PART I

Item 1. Business.

Company Overview and Highlights

We are a biopharmaceutical company focused on developing therapies that restore function and improve the lives of people with neurological disorders. We market Inbrija (levodopa inhalation powder), which is approved in the U.S. for intermittent treatment of OFF episodes, also known as OFF periods, in people with Parkinson’s disease treated with carbidopa/levodopa. Inbrija is for as needed use and utilizes our ARCUS pulmonary delivery system, a technology platform designed to deliver medication through inhalation that we believe has potential to be used in the development of a variety of inhaled medicines. We also market branded Ampyra (dalfampridine) Extended Release Tablets, 10 mg.

Inbrija

Our New Drug Application, or NDA, for Inbrija was approved by the U.S. Food and Drug Administration, or FDA, on December 21, 2018. The approval is for a single dose of 84 mg (administered as two capsules), which may be taken up to five times per day. Inbrija became commercially available in the U.S. on February 28, 2019. Currently, Inbrija is available in the U.S. without the need for a medical exception for approximately 96% of commercial health insurance plan and approximately 25% of Medicare plan lives. Approximately one million people in the U.S. and 1.2 million Europeans are diagnosed with Parkinson’s; it is estimated that approximately 40% of people with Parkinson’s in the U.S. experience OFF periods. Net revenue for Inbrija was $24.2 million for the year ended December 31, 2020. We project peak U.S. annual net revenue of Inbrija to be in the range of $300 to $500 million.

In September 2019, we announced that the European Commission, or EC, approved our Marketing Authorization Application, or MAA, for Inbrija. The approved dose is 66 mg (administered as two capsules) up to five times per day (per European Union, or EU, convention, this reflects emitted dose and is equivalent to the 84 mg labelled dose in the U.S.). Under the MAA, Inbrija is indicated in the EU for the intermittent treatment of episodic motor fluctuations (OFF episodes) in adult patients with Parkinson’s disease treated with a levodopa/dopa-decarboxylase inhibitor. Following the ratification of the Withdrawal Agreement between the United Kingdom and the EU, the UK left the EU on January 31, 2020. Effective January 1, 2021, Acorda was granted a grandfathered Marketing Authorization (MA) by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK which is subject to certain administrative filings that are due by December 31, 2021. We are in discussions with potential partners regarding the distribution of Inbrija outside of the U.S., with potential partners in Europe and Japan.

Ampyra

Ampyra became subject to competition from generic versions of Ampyra starting in late 2018 as a result of an adverse U.S. federal district court ruling that invalidated certain Ampyra Orange Book-listed patents. We have experienced a significant decline in Ampyra sales due to competition from several generic versions of Ampyra. Additional manufacturers may market generic versions of Ampyra, and we expect our Ampyra sales will continue to decline over time. Net revenue for Ampyra was $98.1 million for the year ended December 31, 2020.

On October 30, 2020, we received a $15 million milestone payment from Biogen International GmbH under our license and collaboration with Biogen. Biogen markets Ampyra outside the U.S. as Fampyra. We became entitled to the milestone payment based on Biogen’s ex-U.S. net sales of Fampyra exceeding $100 million over the four consecutive quarters ending with the third quarter of 2020. This payment was recorded as milestone revenue in the third quarter. We retained approximately $14 million of the milestone payment net of our payment obligations to another party.

Convertible Notes

In December 2019, we announced the successful completion of a private exchange of $276 million of our convertible senior notes due in 2021 in exchange for a combination of approximately $207 million aggregate principal amount of newly-issued convertible senior secured notes due 2024 and $55.2 million in cash. The convertible senior secured notes due 2021 have an adjusted conversion price of approximately $21.00 per share. As a result of the exchange, approximately $69 million of convertible senior notes due in 2021, with an adjusted conversion price of approximately $255.35, remain outstanding.

1

Addressing the remaining portion of the convertible notes due 2021 is a top priority in addition to our focus on the Inbrija launch. More information about the terms and conditions of the 2021 and 2024 convertible notes is set forth in Note 9 to our Consolidated Financial Statements included in this report as well as in Financing Arrangements in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of this report.

Sale of Chelsea, Massachusetts Manufacturing Operations

In February 2021, we completed the sale of our Chelsea, Massachusetts manufacturing operations to Catalent Pharma Solutions. Pursuant to the transaction, Catalent paid us $80 million in cash, resulting in net proceeds to us of approximately $74 million after transaction fees and expenses and settlement of customary post-closing adjustments. In connection with the sale of the manufacturing operations, we entered into a long-term, global manufacturing services agreement with a Catalent affiliate for the supply of Inbrija. As part of the transaction, Catalent hired substantially all of our prior employees at the Chelsea facility as well as certain of our other employees at our Waltham, Massachusetts facility. We intend to use the net proceeds received from the transaction for general corporate purposes, subject to compliance with the terms of the 2024 notes, which may include funding capital expenditures and the repayment of indebtedness. Also, we expect to save approximately $10 million in annual operating expenses related to the operation of the manufacturing facility. More information about the Catalent transaction is set forth below under Catalent Transaction. See Note 7 to our Consolidated Financial Statements included in this report for additional information on the assets classified as held for sale as a result of the transaction.

Financial Management

In January 2021, we announced a corporate restructuring to reduce costs and focus our resources on Inbrija, which is our key strategic priority for 2021. As part of the restructuring, we reduced headcount by approximately 16% through a reduction in force (excluding the employees that transferred to Catalent at the closing of the sale of our Chelsea manufacturing operations). All of the reduction in personnel will take place in the first quarter of 2021. As a result, we expect to realize estimated annualized cost savings related to headcount reduction of approximately $6 million beginning in the second quarter of 2021. We estimate that we will incur approximately $3.2 million of pre-tax charges, substantially all of which will be cash expenditures, for severance and other employee separation-related costs in the first quarter of 2021.

In January 2021, we entered into an At The Market (ATM) Offering Agreement with H.C. Wainwright & Co., LLC as sales agent. Pursuant to the ATM agreement, we may offer and sell shares of our common stock having an aggregate value of up to $15.25 million in an at-the-market offering, subject to a 3% sales commission payable to H.C. Wainwright. If we elect to use the ATM agreement, H.C. Wainwright would be obligated to use commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell shares in accordance with our instructions (including as to price, time or size limit or other parameters or conditions that we may impose).

On July 13, 2020, we received a U.S. income tax refund from the Internal Revenue Service of approximately $12.4 million plus interest of $0.3 million, pursuant to the Coronavirus Aid, Relief, and Economic Security Act (CARES Act). Under the CARES Act, among other things, net operating losses arising in a taxable year beginning after December 31, 2017, and before January 1, 2021, can be carried back to the preceding five years to apply against taxable income reported in such years. Pursuant to this provision of the CARES Act, the Company was eligible to carry back 2019 net operating losses to tax years 2017 and 2018, resulting in the refund.

As of December 31, 2020, we had cash, cash equivalents, short-term investments and restricted cash of approximately $102.9 million. Restricted cash includes $31.1 million in escrow related to the 6% semi-annual interest portion of the convertible senior secured notes due 2024, payable in cash or stock. As further described in Note 9 to our Consolidated Financial Statements included in this report as well as in Financing Arrangements in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of this report, if we are permitted under the notes indenture and we elect to pay interest due in stock, the cash equivalent will be released from escrow. In December 2020, we issued 1,484,871 shares to the holders of the 2024 notes in satisfaction of approximately $6.2 million in interest due on December 1, 2020, and a corresponding amount was released from the escrow in late December 2020.

Nasdaq Listing Rules and Reverse Stock Split

On January 19, 2021, we received a letter from The Nasdaq Stock Market, LLC notifying us that we had regained compliance with Listing Rule 5450(a)(1), which requires that listed securities maintain a minimum closing bid price of at

2

least $1.00 per share (the “Minimum Bid Requirement”). We regained compliance with the Minimum Bid Requirement based on the closing bid price of our common stock on the Nasdaq Global Select Market between January 4, 2021 and January 15, 2021. We had previously been notified, on July 23, 2020, of our non-compliance with the Minimum Bid Requirement.

On December 31, 2020, we filed an amendment to our Certificate of Incorporation which effected, as of 4:01 p.m. Eastern Time on December 31, 2020, a 1-for-6 reverse stock split of the shares of our outstanding common stock and proportionate reduction in the number of authorized shares of our common stock from 370,000,000 to 61,666,666. Our Board of Directors approved the reverse stock split as part of plan to regain compliance with the Minimum Bid Requirement. The reverse stock split had previously been authorized by our stockholders at a special meeting convened on July 31, 2020.

Our common stock began trading on a split-adjusted basis on The Nasdaq Global Select Market commencing upon market open on January 4, 2021. The common stock continued to trade under the symbol “ACOR” after the reverse stock split became effective. The reverse stock split applied equally to all outstanding shares of the common stock and did not modify the rights or preferences of the common stock. The reverse stock split also resulted in a corresponding adjustment to outstanding equity awards as well as shares reserved for future issuance under our incentive compensation plans.

All figures in this report relating to shares of our common stock (such as share amounts, per share amounts, and conversion rates and prices), including in the financial statements and accompanying notes to the financial statements, have been retroactively restated to reflect the 1-for-6 reverse stock split of our common stock.

COVID-19 Pandemic

Our business and financial condition have been impacted by, and are subject to risks resulting from, the COVID-19 (novel coronavirus) pandemic. The COVID-19 pandemic has caused significant disruptions in the healthcare industry. The duration of the pandemic is difficult to predict, and it is likely to have ongoing impacts as it continues. The travel restrictions, “shelter in place” orders, quarantine policies, and general concerns about the spread of COVID-19 have disrupted the delivery of healthcare to patients, for example making it more difficult for some patients to visit with their physician and obtain pharmaceutical prescriptions. Also, healthcare office staffing shortages may delay the administrative work, and particularly insurance-related documentation, needed to obtain reimbursement for prescriptions. We believe these factors contributed to volatility in new Inbrija prescriptions during 2020.

The COVID-related policies, restrictions and concerns may disrupt our operations and those of our customers and suppliers. Also, our operations could be interrupted if we or our customers or suppliers lose the services of key employees or consultants who become ill from COVID-19. These types of disruptions could potentially affect any of our critical business functions, and thus harm our business, including for example our manufacturing, sales and marketing operations as well compliance and certain general and administrative functions. The ultimate impact of the COVID-19 pandemic, or any other health epidemic, is highly uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, healthcare systems or the global economy as a whole. As the pandemic continues, it may result in a sustained economic downturn that could affect demand for our products and our ability to access capital on reasonable terms, or at all.

Catalent Transaction

In February 2021, we completed the sale of our Chelsea, Massachusetts manufacturing operations to Catalent Pharma Solutions. Pursuant to the transaction, Catalent paid us $80 million in cash, resulting in net proceeds to us of approximately $74 million after transaction fees and expenses and settlement of customary post-closing adjustments. In connection with the sale of the manufacturing operations, we entered into a long-term, global manufacturing services agreement with a Catalent affiliate for the supply of Inbrija. As part of the transaction, Catalent hired substantially all of our prior employees at the Chelsea facility as well as certain of our other employees at our Waltham, Massachusetts facility. We intend to use the net proceeds received from the transaction for general corporate purposes, subject to compliance with the terms of the 2024 notes, which may include funding capital expenditures and the repayment of indebtedness. Also, we expect to save approximately $10 million in annual operating expenses related to the operation of the manufacturing facility.

3

Asset Purchase Agreement

The Catalent transaction was completed pursuant to an asset purchase agreement that we entered into with Catalent in January 2021. Pursuant to the Catalent asset purchase agreement, upon completion of the sale of the manufacturing operations, Catalent assumed our existing lease to the Chelsea facility, acquired the manufacturing equipment and related manufacturing operations located at our Chelsea manufacturing facility, and acquired certain assets located at our Waltham, Massachusetts facility. Under the asset purchase agreement, both we and Catalent agreed to indemnify the other party for losses arising from certain breaches of the asset purchase agreement and other specified liabilities, subject to certain limitations. In connection with completion of the sale of the manufacturing operations, we and Catalent entered into certain additional ancillary agreements, including the Inbrija supply agreement, a transitional services agreement and certain other customary agreements.

Manufacturing Services Agreement

The Catalent manufacturing services agreement provides that Catalent will manufacture Inbrija (levodopa inhalation powder), to our specifications, and we will purchase Inbrija exclusively from Catalent during the term of the manufacturing services agreement; provided that such exclusivity requirement will not apply to Inbrija intended for sale in China.

The manufacturing services agreement, unless earlier terminated, will continue until December 31, 2030, and will be automatically extended for successive two-year periods unless either we or Catalent provides the other party with at least 18-months’ prior written notice of non-renewal. Either party may terminate the manufacturing services by written notice under certain circumstances, including material breach by the other party (subject to specified cure periods) or the insolvency of the other party. We may also terminate the manufacturing services agreement upon certain specified regulatory events and for convenience upon 180 days’ prior written notice, subject to payment of a specified substantial termination fee.

Under the manufacturing services agreement, we agreed to purchase from Catalent at least $16 million of Product in 2021 (pro-rated for a partial year) and $18 million of Product from 2022 through 2030 (and an additional amount in the last year in the case of such a proration), subject to reduction in certain cases. We will be obligated to provide Catalent with a rolling 24-month forecast of production requirements, a portion of which will be considered a binding, firm order by us. Catalent will be required to reserve sufficient capacity for the manufacture of a specified amount of Inbrija per year, with such capacity reservation to be reviewed on an annual basis.

In addition, the manufacturing services agreement grants to Catalent a non-exclusive, paid-up, royalty-free, non-transferrable, non-assignable, non-sublicensable license to certain of our intellectual property in order to enable the manufacture of Inbrija. Catalent has granted to us a worldwide, perpetual, irrevocable, non-exclusive, paid-up, royalty-free, assignable and sublicensable license to certain of its intellectual property as reasonably necessary to allow us to commercialize Inbrija.

The manufacturing services agreement contains customary representations, warranties and covenants, including with respect to the ownership of any intellectual property created pursuant to the manufacturing services agreement, as well as provisions relating to ordering, payment and shipping terms, regulatory matters, reporting obligations, indemnity, confidentiality and other matters.

Our Strategy

Our long-term strategy is to grow as a fully integrated biopharmaceutical company and to become a leading neurology company dedicated to the identification, development and commercialization of therapies that restore function and improve the lives of people with neurological disorders. For 2021, our strategic priorities include:

4

Our Products and Product Pipeline

* In November 2017, we announced a $40 million Fampyra royalty monetization transaction with HealthCare Royalty Partners, or HCRP. In return for the payment to us, HCRP obtained the right to receive royalties on Fampyra payable to us by Biogen, up to an agreed-upon threshold of royalties. Until this threshold is met, if ever, we will not receive Fampyra royalty revenue although we have retained the right to receive any potential future milestone payments from Biogen.

** In November 2017, we announced a royalty monetization with Lundbeck pursuant to which our Biotie subsidiary received a $13 million payment from Lundbeck in exchange for an amendment to its Selincro license eliminating Lundbeck’s future royalty and milestone obligations on sales of Selincro outside of the U.S. Selincro is not approved for use in the U.S. and is not under development for use in the U.S.

Background on Neurological Conditions

We are a biopharmaceutical company focused on developing therapies that restore function and improve the lives of people with neurological disorders. Where our neurology programs may also show promise for disorders outside of the nervous system, we may elect to pursue these opportunistically as well. We are focused on developing and marketing therapeutics targeted to the conditions described below, although we have deferred investment in our research and development programs pending additional progress with the Inbrija commercial launch in the U.S. We believe there is significant unmet medical need for these conditions, which can severely impact the lives of those who suffer from them.

Parkinson’s Disease

Parkinson’s disease is a progressive neurodegenerative disorder resulting from the gradual loss of certain neurons in the brain. These neurons are responsible for producing dopamine and that loss causes a range of symptoms including impaired movement, muscle stiffness and tremors. Approximately one million Americans and 1.2 million Europeans suffer from Parkinson’s. There is no cure or disease-modifying treatment currently available for Parkinson’s disease. Current treatment strategies are focused on the management and reduction of the major symptoms of the disease and related disabilities. These

5

therapies either aim to supplement dopamine levels in the brain, mimic the effect of dopamine in the brain by stimulating dopamine receptors or prevent the enzymatic breakdown of dopamine. The standard of care for the treatment of Parkinson’s disease symptoms is oral carbidopa/levodopa. Approximately 70% of people with Parkinson’s disease in the U.S. are treated with oral carbidopa/levodopa. Effective control of Parkinson’s disease symptoms is referred to as an ON state.

As Parkinson’s disease progresses, people are likely to experience OFF periods, also known as OFF episodes, which are characterized by the return of Parkinson’s symptoms, which can occur despite underlying baseline therapy. Even optimized regimens of oral carbidopa/levodopa are associated with increasingly wide variability in the timing and amount of absorption into the bloodstream. This results in the unreliable control of symptoms, leading to motor complications including OFF periods. OFF periods can increase in frequency and severity during the course of the disease, and remain one of the most challenging aspects of the disease despite optimized regimens with current therapeutic options and strategies. About half of people with Parkinson’s disease treated with levodopa therapy experience OFF periods within five years of initiating treatment. For the approximately 350,000 people in the U.S. and 420,000 in Europe who experience them, OFF periods are inadequately addressed by available therapies and are considered one of the greatest unmet medical needs facing people with Parkinson’s disease. OFF periods can be very disruptive to the lives of people with Parkinson’s disease, their families and caregivers. In a survey of 3,000 people with Parkinson’s conducted by the Michael J. Fox Foundation, 64% of respondents reporting having at least two hours of OFF time per day.

Multiple Sclerosis

Multiple Sclerosis, or MS, is a chronic, usually progressive disease in which the immune system attacks and degrades the function of nerve fibers in the brain and spinal cord. These nerve fibers consist of long, thin fibers, or axons, surrounded by a myelin sheath, which facilitates the transmission of electrical impulses, much as insulation facilitates conduction in an electrical wire. In MS, the myelin sheath is damaged by the body's own immune system, causing areas of myelin sheath loss, also known as demyelination. This damage, which can occur at multiple sites in the central nervous system, blocks or diminishes conduction of electrical impulses. Patients with MS may suffer impairments in a wide range of neurological functions. These impairments vary from individual to individual and over the course of time, depending on which parts of the brain and spinal cord are affected, and often include difficulty walking. Individuals vary in the severity of the impairments they suffer on a day-to-day basis, with impairments becoming better or worse depending on the activity of the disease on a given day.

Approximately 400,000 people in the U.S. suffer from MS, and each year approximately 10,000 people in the U.S. are newly diagnosed. In a poll of more than 2,000 people with MS, 87% said they experienced some limitation to their walking ability and limited activities that involved walking. Among MS patients diagnosed within the last 5 years, 58% report experiencing mobility issues at least twice a week. In the European Union, over 700,000 people suffer from MS, and an additional 100,000 people in Canada are also diagnosed with this disease.

Inbrija (levodopa inhalation powder)

Inbrija (levodopa inhalation powder) is the first and only inhaled levodopa, or L-dopa, for intermittent treatment of OFF episodes, also known as OFF periods, in people with Parkinson’s disease treated with carbidopa/levodopa regimen. Our New Drug Application, or NDA, for Inbrija was approved by the U.S. Food and Drug Administration, or FDA, on December 21, 2018. The approval is for a single dose of 84 mg (administered as two capsules), which may be taken up to five times per day. Inbrija became commercially available in the U.S. on February 28, 2019. Currently, Inbrija is available in the U.S. without the need for a medical exception for approximately 96% of commercial health insurance plan and approximately 25% of Medicare plan lives. Net revenue for Inbrija was $24.2 million for the year ended December 31, 2020. We project peak U.S. annual net revenue of Inbrija to be in the range of $300 to $500 million.

In September 2019, we announced that the European Commission, or EC, approved our Marketing Authorization Application, or MAA, for Inbrija. The approved dose is 66 mg (administered as two capsules) up to five times per day (per European Union, or EU, convention, this reflects emitted dose and is equivalent to the 84 mg labelled dose in the U.S.). Under the MAA, Inbrija is indicated in the EU for the intermittent treatment of episodic motor fluctuations (OFF episodes) in adult patients with Parkinson’s disease treated with a levodopa/dopa-decarboxylase inhibitor. The MAA approved Inbrija for use in what were then the 27 countries of the EU, as well as Iceland, Norway and Liechtenstein. Following the ratification of the Withdrawal Agreement between the United Kingdom and the EU, the UK left the EU on January 31, 2020. Effective January 1, 2021, Acorda was granted a grandfathered Marketing Authorization (MA) by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK which is subject to certain administrative filings that are due by December

6

31, 2021. We are in discussions with potential partners regarding the distribution of Inbrija outside of the U.S., with potential partners in Europe and Japan.

Inbrija is marketed in the U.S. through our own specialty sales force and commercial infrastructure, which we are supplementing with sales representatives provided by a contract commercial organization. Inbrija is distributed in the U.S. primarily through: Alliance Rx Walgreens Prime, or Walgreens, a specialty pharmacy that delivers the medication to patients by mail; and ASD Specialty Healthcare, Inc. (an AmeriSource Bergen affiliate). During 2020, we transitioned from a network of several specialty pharmacies to Walgreens as the sole specialty pharmacy for U.S. sales of Inbrija, which we believe has potential benefits to patients and our business. Our neuro-specialty sales and marketing team includes our own sales representatives as well as established teams of Medical Science Liaisons, Regional Reimbursement Directors, and Market Access Account Directors who provide information to payers and physicians on our marketed products; and Market Development Managers who work collaboratively with field teams and corporate personnel to assist in the execution of the Company’s strategic initiatives. Our sales representatives (with the contracted representatives) are targeting approximately 5,000 healthcare providers, currently focusing on a priority list of approximately 2,000 physicians who are high volume prescribers of levodopa/carbidopa. Our Inbrija launch activities are focused on physician awareness and market access as well as patient awareness, education and training.

We have established Prescription Support Services for Inbrija, which we sometimes refer to as the Inbrija hub. Prescription Support Services is designed to help patients navigate their insurance coverage and offer reimbursement support services, when appropriate. Services fall into one of these categories: insurance verification, to research patient insurance benefits and confirm insurance coverage; prior authorization support, to identify prior authorization requirements; and appeals support. For patients that may need assistance paying for their medication, Prescription Support Services offers several support options, including: a program that provides no cost medication to patients who meet specific program eligibility requirements; co-pay support, which may help commercially insured (non-government funded) patients lower their out-of-pocket costs; and a bridge program, for federally-insured patients who experience a delay in coverage determination. We have implemented a no-cost sample program, available at physician offices, to enable patients and their physicians to assess the value of Inbrija before the patient incurs out-of-pocket co-pay or co-insurance costs. In addition, we have implemented a free trial program, available through the Inbrija hub, for commercially insured patients who cannot access the free samples because of offices and institutions that have policies that prohibit samples.

Parkinson’s disease is a progressive neurodegenerative disorder resulting from the gradual loss of certain neurons in the brain. These neurons are responsible for producing dopamine and that loss causes a range of symptoms including impaired movement, muscle stiffness and tremors. The standard baseline treatment of Parkinson’s disease is oral carbidopa/levodopa, but oral medication can be associated with wide variability in the timing and amount of absorption and there are significant challenges in creating a regimen that consistently maintains therapeutic effects. As Parkinson’s progresses, people are likely to experience OFF periods, which are characterized by the return of Parkinson’s symptoms that result from low levels of dopamine between doses of oral carbidopa/levodopa. OFF periods are often highly disruptive to people with Parkinson’s. Approximately one million people in the U.S. and 1.2 million Europeans are diagnosed with Parkinson’s; it is estimated that approximately 40% of people with Parkinson’s in the U.S. experience OFF periods.

Inbrija is for as needed use and utilizes our ARCUS platform for inhaled therapeutics. ARCUS is a dry-powder pulmonary drug delivery technology that we believe has potential to be used in the development of a variety of inhaled medicines. The ARCUS platform allows systemic delivery of medication through inhalation, by transforming molecules into a light, porous dry powder. This allows delivery of substantially higher doses of medication than can be delivered via conventional dry powder technologies. We acquired the ARCUS technology platform as part of our 2014 acquisition of Civitas Therapeutics. We have worldwide rights to our ARCUS drug delivery technology, which is protected by extensive know-how and trade secrets and various U.S. and foreign patents, including patents that protect the Inbrija dry powder capsules beyond 2030. We have several patents listed in the Orange Book for Inbrija, including patents expiring between 2022 and 2032, and Inbrija is entitled to three years of new product exclusivity, through December 2021, as posted in the Orange book.

Clinical Studies and Safety Profile

FDA and European Commission approvals of Inbrija were based on a clinical program that included approximately 900 people with Parkinson’s on a carbidopa/levodopa regimen experiencing OFF periods. The Phase 3 pivotal trial for Inbrija – SPAN-PD – was a 12-week, randomized, placebo controlled, double blind study evaluating the effectiveness of Inbrija in patients with mild to moderate Parkinson’s experiencing OFF periods. In January 2019, we announced that The Lancet Neurology published results from the SPAN-PD clinical trial.

7

The SPAN-PD trial met its primary endpoint, with patients showing a statistically significant improvement in motor function at the week 12 visit, as measured by a reduction in Unified Parkinson’s Disease Rating Scale (UPDRS) Part III score for Inbrija 84 mg (n=114) compared to placebo (n=112) at 30 minutes post-dose (-9.83 points and -5.91 points respectively; p=0.009). Onset of action was seen as early as 10 minutes. Maintenance of effect continued to 60 minutes post-dose, which is the longest time point assessed in the trial. UPDRS III is a validated scale, which measures Parkinson’s disease motor impairment.

The most common adverse reactions with Inbrija (at least 5% and greater than placebo) in the pivotal trial were cough (15% vs. 2%), upper respiratory tract infection (6% vs. 3%), nausea (5% vs. 3%) and discolored sputum (5% vs. 0%).

Inbrija was also studied in a Phase 3 long-term, active-controlled, randomized, open-label study (N=398) assessing safety and tolerability over one year. This study showed the average reduction in FEV1 (forced expiratory volume in 1 second) from baseline was the same (-0.1 L) for the Inbrija and observational cohorts. Patients with chronic obstructive pulmonary disease (COPD), asthma, or other chronic respiratory disease within the last five years were excluded from this study.

Inbrija is not to be used by patients who take or have taken a nonselective monoamine oxidase inhibitor such as phenelzine or tranylcypromine within the last two weeks.

Additional Important Safety Information

Before using Inbrija, patients should tell their healthcare provider about all their medical conditions, including:

Patients should tell their healthcare provider if they take:

No more than 1 dose (2 capsules) should be taken for any OFF period. No more than 5 doses (10 capsules) of Inbrija should be taken in a day.

8

Inbrija is for oral inhalation only. Inbrija capsules are not to be swallowed or opened.

Patients are not to drive, operate machinery, or do other activities until they know how Inbrija affects them. Sleepiness and falling asleep suddenly can happen as late as a year after treatment is started.

Inbrija (levodopa inhalation powder) can cause serious side effects including the following. Patients should tell their healthcare provider if they experience them:

The most common side effects of Inbrija include cough, upper respiratory tract infection, nausea, and change in the color of saliva or spit.

It is not known if Inbrija is safe or effective in children.

Ampyra

Ampyra (dalfampridine) is an oral drug approved by the FDA in January 2010 as a treatment to improve walking in adults with multiple sclerosis. This was demonstrated by an increase in walking speed. Ampyra demonstrated efficacy in people with all four major types of multiple sclerosis (relapsing remitting, secondary progressive, progressive relapsing and primary progressive). Ampyra can be used alone or with concurrent medications, including immunomodulatory drugs. The majority of patients in our two Phase 3 clinical trials for Ampyra (63%) were taking immunomodulatory drugs (interferons, glatiramer acetate, or natalizumab). Ampyra is an extended release tablet formulation of dalfampridine (4-aminopyridine, 4-AP), which had previously been referred to as fampridine. Dalfampridine is a potassium channel blocker. In animal studies, dalfampridine has been shown to increase conduction of nerve signals in demyelinated axons through blocking of potassium channels. The mechanism by which dalfampridine exerts its therapeutic effect has not been fully elucidated.

9

Ampyra became subject to competition from generic versions of Ampyra starting in late 2018 as a result of an adverse U.S. federal district court ruling that invalidated certain Ampyra Orange Book-listed patents. We have experienced a significant decline in Ampyra sales due to competition from several generic versions of Ampyra. Additional manufacturers may market generic versions of Ampyra, and we expect our Ampyra sales will continue to decline over time. Net revenue for Ampyra was $98.1 million for the year ended December 31, 2020.

License and Collaboration Agreement with Biogen

Ampyra is marketed as Fampyra outside the U.S. by Biogen International GmbH, or Biogen, under a license and collaboration agreement that we entered into in June 2009. Fampyra has been approved in a number of countries across Europe, Asia and the Americas. Under our agreement with Biogen, we are entitled to receive double-digit tiered royalties on net sales of Fampyra and we are also entitled to receive additional payments based on achievement of certain regulatory and sales milestones. In October 2020, we received a $15 million milestone payment from Biogen based on ex-U.S. net sales exceeding $100 million over the four consecutive quarters ending with the third quarter of 2020. This payment was recorded as milestone revenue in the third quarter. We retained approximately $14 million of the milestone payment net of our payment obligations to another party. In November 2017, we announced a $40 million Fampyra royalty monetization transaction with HealthCare Royalty Partners, or HCRP. In return for the payment to us, HCRP obtained the right to receive these Fampyra royalties up to an agreed-upon threshold. Until this threshold is met, if ever, we will not receive Fampyra royalties although we retained the right to receive any potential future milestone payments, including the milestone payment described above. The HCRP transaction is accounted for as a liability, as described in Note 10 to our Consolidated Financial Statements included in this report.

Ampyra Patent Update

There are no patents listed in the Orange Book for Ampyra. Ampyra became subject to competition from generic versions of Ampyra starting in late 2018 as a result of an adverse U.S. federal district court ruling that invalidated certain Ampyra Orange Book-listed patents.

There are two European patents, EP 1732548 and EP 2377536, with claims directed to use of a sustained release dalfampridine composition (known under the trade name Fampyra in the European Union) to increase walking speed in a patient with multiple sclerosis. Both European patents are set to expire in 2025, absent any additional exclusivity granted based on regulatory review timelines. Nullity actions have been filed in Germany against both of the German national patents derived from EP 1732548 and EP 2377536 by ratiopharm GmbH, a generic manufacturer affiliated with Teva. Fampyra also has 10 years of market exclusivity in the European Union that is set to expire in 2021.

We will vigorously defend our intellectual property rights.

Clinical Studies and Safety Profile

Our New Drug Application, or NDA, for Ampyra was based on data from a comprehensive development program assessing the safety and efficacy of Ampyra, including two Phase 3 trials that involved 540 people with MS. The primary measure of efficacy in our two Phase 3 MS trials was walking speed (in feet per second) as measured by the Timed 25-foot Walk (T25FW), using a responder analysis. A responder was defined as a patient who showed faster walking speed for at least three visits out of a possible four during the double-blind period than the maximum speed achieved in the five non-double-blind, no treatment visits (four before the double-blind period and one after). A significantly greater proportion of patients taking Ampyra 10 mg twice daily were responders compared to patients taking placebo, as measured by the T25FW (Trial 1: 34.8% vs. 8.3%; Trial 2: 42.9% vs. 9.3%). The increased response rate in the Ampyra group was observed across all four major types of MS. During the double-blind treatment period, a significantly greater proportion of patients taking Ampyra 10 mg twice daily had increases in walking speed of at least 10%, 20%, or 30% from baseline, compared to placebo. In both trials, the consistent improvements in walking speed were shown to be associated with improvements on a patient self-assessment of ambulatory disability, the 12 item Multiple Sclerosis Walking Scale (MSWS-12), for both drug and placebo treated patients. However, a drug vs. placebo difference was not established for that outcome measure.

In October 2015, we presented 5-year post-marketing safety data for dalfampridine extended release tablets in MS at the 31^st Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) annual meeting.

10

The data presented continue to be consistent with those reported in double-blind clinical trials, with incidence of reported seizure remaining stable over time.

The FDA’s approval letter included certain post-marketing study requirements and confirmed certain commitments made by us with respect to Ampyra, all of which we have now completed. The post-marketing requirements included additional animal toxicology studies to evaluate certain impurities, in-vitro receptor binding and abuse potential studies in animals, and an evaluation of clinical adverse events related to abuse potential. We completed these studies and timely submitted the results to the FDA. Also, we committed to the FDA that we would conduct a placebo-controlled trial to evaluate a 5 mg twice-daily dosing regimen of Ampyra, as well as a pharmacokinetic evaluation of a 7.5 mg dosage strength in patients with mild or moderate renal impairment. We also committed to report all post-marketing seizure events on an expedited basis to the FDA. We completed the renal impairment study and timely submitted the results to the FDA, but the FDA may require additional studies. In August 2012, we announced results of the 5mg efficacy study. The study failed to confirm efficacy of the 5mg dose. We believe that this study, together with Ampyra registration studies, continue to show that 10mg twice daily is the appropriate, safe, and effective dose. The study results were provided to the FDA, which subsequently confirmed that we have satisfied this post-marketing requirement.

In our two Phase 3 clinical studies of Ampyra in spinal cord injury, which were completed in 2004, the results did not reach statistical significance on their primary endpoints.

ARCUS Product Development

We have been exploring opportunities for other proprietary products in which inhaled delivery of medicine using our ARCUS drug delivery technology can provide a significant therapeutic benefit to patients. We believe there are potential opportunities with central nervous system, or CNS, as well as non-CNS, disorders.

Our ARCUS development has been focused on a program for acute treatment of migraine. Existing oral therapies for migraine can be associated with slow onset of action and gastrointestinal challenges. Patients cite the need for rapid relief from migraine symptoms as their most desired medication attribute. Additionally, individuals with migraine may suffer from nausea and delayed gastric emptying which further impact the consistency and efficacy of the oral route of administration. We have been evaluating therapeutic candidates for their suitability to move forward with this program. Due to our three restructurings since 2017 and associated cost-cutting measures, we have deferred consideration of further investment into potential new ARCUS applications in migraine pending additional progress with the Inbrija commercial launch in the U.S.

Should we decide in the future to make investments in any ARCUS development program, we would be reliant on Catalent Pharma Solutions for the manufacture of product for that program. Our global supply agreement with Catalent does not provide for the terms and conditions under which Catalent would supply any product or product candidate other than Inbrija. We would be unable to advance the development of any ARCUS inhaled therapeutic candidate unless Catalent is willing to manufacture the candidate for us on commercially reasonable terms. Also, due to reductions in force, employee attrition and the 2021 sale of our Chelsea manufacturing operations, we believe we lack certain personnel needed for, and would need to hire replacements before continuing with, this research and development work.

In July 2015, the Bill & Melinda Gates Foundation awarded us a grant to support the development of a formulation and delivery system for a dry powder version of lung surfactant, a treatment for neonatal respiratory distress syndrome, or nRDS. In collaboration with the Massachusetts Institute of Technology, we developed a formulation and delivery device based on our proprietary ARCUS drug delivery technology. nRDS is a condition affecting prematurely born infants in which their lungs are underdeveloped and thus lack a sufficient amount of lung surfactant. It can be fatal, or lead to severe, chronic health issues caused by a lack of oxygen getting to the baby’s brain and other organs. Delivering liquid surfactant to the lungs via intubation is the standard of care. We believe that our formulation and delivery system may present a more practical alternative for use in developing areas of the world, where intubation poses numerous problems. Based on achievement of pre-clinical proof of concept, the foundation expanded the funding to include pre-IND development, including an additional grant of approximately $2.08 million in 2020 to continue this work. This program is not aimed at developing a commercial product, but our work on this program could potentially generate information that is useful for adapting the ARCUS drug delivery technology to commercial pediatric uses. We expect all current grant-funded work to be completed in the first half of 2021. We are evaluating next steps for our continuing involvement in this program as it transitions past the grant-funding stage and in light of the sale of our Chelsea manufacturing operations and other factors.

Other Research and Development Programs

Our other research and development programs include rHIgM22 and cimaglermin alfa. rHIgM22 is a remyelinating antibody that is a potential therapeutic for multiple sclerosis. Data from a Phase 1 safety and tolerability trial showed that a single dose of rHIgM22 was not associated with any safety signals. The study was not powered to show efficacy and exploratory measures showed no difference between the treatment groups. Cimaglermin alfa is a member of the neuregulin growth factor family, and has been shown to promote recovery after neurological injury, as well as enhance heart function in animal models of heart failure. We initiated a Phase 1b clinical trial assessing three doses of cimaglermin alfa in people with heart failure, but discontinued enrollment and then received an FDA clinical hold based on the occurrence of a case of hepatotoxicity (liver injury). The FDA clinical hold was lifted after we presented additional data on the hepatotoxicity, but we have not since restarted any clinical study of cimaglermin alfa. We are considering next steps for these programs, which could include potential partnering or out-licensing, but due to our three restructurings since 2017 and associated cost-cutting measures, we have deferred consideration of any further investment pending additional progress with the Inbrija commercial launch in the U.S.

Sales, Marketing and Market Access

Inbrija (levodopa inhalation powder)

Inbrija is marketed in the U.S. through our own specialty sales force and commercial infrastructure, which we are supplementing with sales representatives provided by a contract commercial organization. Inbrija is distributed in the U.S. primarily through:  Alliance Rx Walgreens Prime, or Walgreens, a specialty pharmacy that delivers the medication to patients by mail; and ASD Specialty Healthcare, Inc. (an AmeriSource Bergen affiliate). During 2020, we transitioned from a network of several specialty pharmacies to Walgreens as the sole specialty pharmacy for U.S. sales of Inbrija, which we believe has potential benefits to patients and our business. Our neuro-specialty sales and marketing team includes our own sales representatives as well as established teams of Medical Science Liaisons, Regional Reimbursement Directors, and Market Access Account Directors who provide information to payers and physicians on our marketed products; and Market Development Managers who work collaboratively with field teams and corporate personnel to assist in the execution of the Company’s strategic initiatives. Our sales representatives (with the contracted representatives) are targeting approximately 5,000 healthcare providers, currently focusing on a priority list of approximately 2,000 physicians who are high volume prescribers of levodopa/carbidopa. Our Inbrija launch activities are focused on physician awareness and market access as well as patient awareness, education and training.

We have established Prescription Support Services for Inbrija, which we sometimes refer to as the Inbrija hub. Prescription Support Services is designed to help patients navigate their insurance coverage and offer reimbursement support services, when appropriate. Services fall into one of these categories: insurance verification, to research patient insurance benefits and confirm insurance coverage; prior authorization support, to identify prior authorization requirements; and appeals support. For patients that may need assistance paying for their medication, Prescription Support Services offers several support options, including: a program that provides no cost medication to patients who meet specific program eligibility requirements; co-pay support, which may help commercially insured (non-government funded) patients lower their out-of-pocket costs; and a bridge program, for federally-insured patients who experience a delay in coverage determination. We have implemented a no-cost sample program, available at physician offices, to enable patients and their physicians to assess the value of Inbrija before the patient incurs out-of-pocket co-pay or co-insurance costs. In addition, we have implemented a free trial program, available through the Inbrija hub, for commercially insured patients who cannot access the free samples because of offices and institutions that have policies that prohibit samples.

Ampyra

Ampyra is marketed in the U.S. through our own specialty sales force and commercial infrastructure, which we are supplementing with sales representatives provided by a contract commercial organization, and is distributed in the U.S. primarily through a network of specialty pharmacies, which deliver the medication to patients by mail. We have contracted with a third party organization with extensive experience in coordinating patient benefits to run Ampyra Patient Support Services, or APSS, a dedicated resource that coordinates the prescription process among healthcare providers, people with multiple sclerosis, and insurance carriers. We have a 60-day free trial program that provides eligible patients with two months of Ampyra at no cost. We are evaluating the level of our continuing investment in certain Ampyra sales and marketing programs, including our free trial program and APSS, due to the introduction of generic competition and corresponding decline in Ampyra sales.

Material and Other Collaborations and License Agreements

Alkermes (ARCUS products)

On December 27, 2010, Civitas, our wholly-owned subsidiary, entered into an Asset Purchase and License Agreement with Alkermes, Inc. pursuant to which Alkermes assigned, sold and transferred to Civitas certain of its rights in certain pulmonary delivery patents and patents applications, certain equipment and instruments relating to pulmonary drug delivery, copies of certain documents and reports relating to pulmonary delivery, certain pulmonary drug delivery inhalers and certain pulmonary drug delivery Investigational New Drug Applications, or INDs, filed with the FDA. Alkermes also granted to Civitas a non-exclusive sublicense to know-how for the purpose of development and commercialization of ARCUS products. Civitas is permitted to license and sublicense the pulmonary patents, patent applications and know-how, subject to certain restrictions, as necessary for our business. Without the prior written consent of Alkermes, Civitas is prohibited from assigning the intellectual property acquired from Alkermes, except to an affiliate or to a person that acquires all or substantially all of its business to which the agreement relates, whether by acquisition, sale, merger or otherwise.

Civitas is required to use commercially reasonable efforts to develop ARCUS products. Civitas is obligated to pay to Alkermes royalties for each licensed product. For licensed products sold by Civitas or an affiliate, Civitas will pay Alkermes a mid-single digit percentage royalty on net sales. For licensed products sold by a collaboration partner, Civitas will pay Alkermes the lower of either (1) a mid-single digit percentage royalty on collaboration partner net sales of licensed products in any given calendar year, or (2) a percentage in the low-to-mid-double digits of all collaboration partner revenue received in such calendar year. Notwithstanding the foregoing, in no event shall the collaboration partner royalty paid be less than a low-single digit percentage of collaboration partner net sales of the licensed product in any given calendar year.

Civitas has the right to terminate the Alkermes agreement at any time upon giving 90 days’ written notice. The Alkermes agreement may also be terminated by either party with respect to certain specified uncured breaches following notice and the expiration of a cure period.

Subject to the termination provisions described above, the Alkermes agreement remains in effect until expiration of Civitas’ royalty obligations to Alkermes. Royalties are payable to Alkermes on a product-by-product and country-by-country basis until the later of (i) the expiration of the patents acquired from Alkermes containing a valid claim covering a product in a particular country and (ii) 12 years and six months after the launch of a product in a country.

Biogen (Fampyra)

In 2009, we entered into a Collaboration Agreement with Biogen, pursuant to which we and Biogen have agreed to collaborate on the development and commercialization of products containing aminopyridines, including Ampyra, initially directed to the treatment of multiple sclerosis, or MS, (licensed products). Under the Collaboration Agreement, Ampyra is marketed by Biogen as Fampyra outside the U.S. Fampyra has been approved in a number of countries across Europe, Asia and the Americas.

The Collaboration Agreement includes a sublicense of our rights under an existing license agreement with Alkermes (formerly Elan). We have also entered into a related Supply Agreement pursuant to which we supply Biogen with its requirements for the licensed products through our existing supply agreement with Alkermes. Biogen Inc., the parent of Biogen, has guaranteed the performance of Biogen's obligations under the Collaboration Agreement and the Supply Agreement.

Under the Collaboration Agreement, Biogen, itself or through its affiliates, has the exclusive right to commercialize licensed products in all countries outside of the U.S., unless rights to a particular country terminate under the terms of the Collaboration Agreement, while we retain the exclusive right to commercialize licensed products in the U.S. Each party has the exclusive right to develop licensed products for its commercialization territory, although the parties may also decide to jointly carry out mutually agreed future development activities under a cost-sharing arrangement. Under the Collaboration Agreement, we participate in overseeing the development and commercialization of Ampyra and other licensed products in markets outside the U.S. in part through our participation in joint committees with Biogen. If Biogen does not participate in the development of licensed products for certain indications or forms of administration, it may lose the right to develop and commercialize the licensed products for such indication or form of administration. Biogen may sublicense its rights to certain unaffiliated distributors. During the term of the Collaboration Agreement and for two years after the Collaboration Agreement terminates, neither party nor its affiliates may, other than pursuant to the Collaboration Agreement, research,

13

develop, manufacture or commercialize any competing product, defined as one that contains aminopyridine or any other compound that acts at least in part through direct interaction with potassium channels to improve neurological function in MS, spinal cord injury or other demyelinating conditions, except that we may exploit the licensed products anywhere in the world following termination of the Collaboration Agreement.

In consideration for the rights granted to Biogen under the Collaboration Agreement, we were entitled to a non-refundable upfront payment of $110.0 million as of June 30, 2009, which was received in July 2009. Also, in August 2011, we received a $25 million milestone payment from Biogen for approval of Fampyra in the EU. Under our separate license and supply agreements with Alkermes, in 2009 we paid Alkermes $7.7 million of the $110 million upfront Biogen payment and in 2011 we paid Alkermes $1.8 million of the $25 million Biogen milestone payment. We are entitled to receive additional payments from Biogen of up to $10 million based on the successful achievement of future regulatory milestones and up to $340 million based on the successful achievement of future sales milestones. On October 30, 2020, we received a $15 million milestone payment from Biogen based on Biogen’s ex-U.S. net sales of Fampyra exceeding $100 million over the four consecutive quarters ending with the third quarter of 2020. This payment was recorded as milestone revenue in the third quarter. We retained approximately $14 million of the milestone payment net of our payment obligations to another party.

Under the Collaboration Agreement, we are also entitled to receive double-digit percentage tiered royalties on net sales of licensed products by Biogen, its affiliates or certain distributors outside of the U.S. Such royalties for products combining a licensed compound with at least one other clinically active therapeutic, prophylactic or diagnostic ingredient are determined based on the contribution of the licensed compound to the overall sales or value of the combination product. Biogen may offset against the royalties payable to us a portion of certain royalties that it may need to pay to third parties. In November 2017, we announced a $40 million Fampyra royalty monetization transaction with HealthCare Royalty Partners, or HCRP. In return for the payment to us, HCRP obtained the right to receive these Fampyra royalties up to an agreed-upon threshold. Until this threshold is met, if ever, we will not receive Fampyra royalties although we have retained the right to receive any potential future milestone payments, described above.

Biogen exclusively purchases all of Biogen's, its affiliates' and its sublicensees' requirements of the licensed products from us. The purchase price paid by Biogen for licensed products under the Collaboration Agreement and Supply Agreement reflects the prices owed to our suppliers under our supply arrangements with Alkermes or other suppliers. In addition, Biogen pays us, in consideration for its purchase and sale of the licensed products, any amounts due to Alkermes for ex-U.S. sales, including royalties owed under the terms of our existing agreements with Alkermes.

The Collaboration Agreement will terminate upon the expiration of Biogen's royalty payment obligations, which occurs, on a licensed product-by-licensed product and country-by-country basis, upon the latest of expiration of the last-to-expire patent covering a licensed product, fifteen years following first commercial sale of such licensed product, the expiration of regulatory exclusivity and the existence of certain levels of sales by competing products. The Collaboration Agreement and the Supply Agreement will automatically terminate upon the termination of our license agreement with Alkermes in its entirety or with respect to all countries outside of the U.S. We cannot terminate our license agreement with Alkermes without Biogen's prior written consent under certain circumstances. Biogen may terminate the Collaboration Agreement in its entirety or on a country-by-country basis at any time upon 180 days' prior written notice, subject to our right to accelerate such termination. The Collaboration Agreement may also be terminated by either party if the other party fails to cure a material breach under the agreement, which termination will be limited to a particular country or region under certain circumstances. However, if Biogen has the right to terminate the Collaboration Agreement due to our material uncured breach, Biogen may instead elect to keep the agreement in effect, but decrease the royalty rates they pay us by a specified percentage. We may also terminate the Collaboration Agreement if Biogen does not commercially launch a licensed product within a specified time period after receiving regulatory approval for such licensed product or otherwise fails to meet certain commercialization obligations. In addition, we may terminate the Collaboration Agreement under certain circumstances if (i) Biogen, its affiliates or its sublicensees challenge certain of our patents or (ii) there is a change in control of Biogen or its parent company or certain dispositions of assets by Biogen, its parent or its affiliated companies, followed by a change in the sales and marketing personnel responsible for the licensed products in Biogen's territory of more than a specified percentage within a certain period of time after such change in control or disposition. The Supply Agreement may be terminated by either party if the other party fails to cure a material breach under the Supply Agreement. In addition, the Supply Agreement will terminate automatically upon termination of the Collaboration Agreement, and the Collaboration Agreement will terminate automatically if the Supply Agreement is terminated for any reason other than for a material breach that we are responsible for. To the extent permitted by law, each party may terminate the Collaboration Agreement and the Supply Agreement if the other party is subject to bankruptcy proceedings.

14

If the Supply Agreement is terminated by Biogen for an uncured material breach, we will waive our right for Alkermes to exclusively supply the licensed products to us solely to permit Biogen to negotiate terms with Alkermes for the supply of licensed products to Biogen. If the Supply Agreement is otherwise terminated, Biogen will not have any future obligations to purchase licensed products from us and we will not have any future obligations to supply Biogen with licensed products. If the Collaboration Agreement is terminated, Biogen will assign to us all regulatory documentation and other information necessary or useful to exploit the licensed products in the terminated countries and will grant us a license under Biogen's and its affiliates' relevant patent rights, know-how and trademarks to exploit the licensed products in the terminated countries. Such assignment and license will be at no cost to us unless the Collaboration Agreement is terminated by Biogen for a material uncured breach that we are responsible for, in which case the parties will negotiate a payment to Biogen to reflect the net value of such assigned and licensed rights.

Neither party may assign the agreements without the prior written consent of the other, except to an affiliate or, in certain cases, to a third party acquirer of the party.

In connection with the entry into the Collaboration Agreement, Biogen and Alkermes entered into a Consent Agreement with us. Under the Consent Agreement, Alkermes consented to our sublicense of rights to Biogen, and the three parties agreed to set up a committee to coordinate activities under our agreements with Alkermes with respect to the development, supply and commercialization of the licensed products for Biogen's territory. The Consent Agreement also amended our agreements with Alkermes by, among other things, permitting us to allow Biogen to grant sublicenses to certain unaffiliated distributors; permitting us to allow Biogen to package the licensed products and to work directly with Alkermes with respect to certain supply-related activities; and, requiring Alkermes to facilitate the qualification of an alternate supplier of the licensed products under certain circumstances.

Alkermes (Ampyra)

We have entered into agreements with Elan Corporation plc, including those described immediately below and elsewhere in this report. In September 2011, Alkermes plc acquired Elan’s Drug Technologies business and Elan transferred our agreements to Alkermes as part of that transaction. Throughout this report, references to “Alkermes” include Alkermes plc and also, as the context may require, Elan Corporation plc as the predecessor to Alkermes plc under our agreements.

In September 2003, we entered into an amended and restated license agreement with Elan that replaced two prior license agreements for Ampyra in oral sustained release dosage form. Under this agreement, Elan granted us exclusive worldwide rights to Ampyra for all indications, including spinal cord injury, or SCI, multiple sclerosis, or MS, and all other indications. We agreed to pay Elan milestone payments of up to $15.0 million, of which we have reached and paid $5.0 million, and royalties based on net sales of products with dalfampridine as the active ingredient. We also agreed to pay Elan 7% of any upfront and milestone payments that we receive from the sublicensing of rights to Ampyra or other aminopyridine products. As a result of our Collaboration Agreement with Biogen, described above, in 2009 we paid Elan $7.7 million of a $110 million upfront payment we received from Biogen, and in 2011 we paid Elan $1.8 million of a $25 million milestone payment we received from Biogen.

Alkermes (now the licensor under this agreement due to its 2011 acquisition of Elan’s Drug Technologies business) is also obligated under this agreement to supply us with our commercial requirements for Ampyra in the U.S., as well as to supply Biogen under the Supply Agreement and Consent Agreement with Fampyra for Biogen’s clinical trials and for Biogen’s commercial requirements.

Alkermes may terminate our license in countries in which we have a license, if we fail to file for regulatory approvals within a commercially reasonable time after completion and receipt of positive data from all preclinical and clinical studies required for the related New Drug Application, or NDA, equivalent. We could also lose our rights under the license agreement if we fail to launch a product in such countries within 180 days of NDA or equivalent approval and receipt of other needed regulatory approvals, or if we fail to fulfill our payment obligations under the license agreement. If Alkermes terminates our license in any applicable country, Alkermes is entitled to license from us our patent rights and know-how relating to the product and to market the product in the applicable country, subject to royalty payments to us.

15

We have the right to terminate the Alkermes license at any time upon 90 days’ written notice. In addition, the Alkermes license may be immediately terminated by either party following an incurable breach of any term or provision by the other party. The Alkermes license may also be terminated by either party following notice and the expiration of a cure period with respect to an uncured breach by either party.

Subject to the termination provisions described above, the Alkermes license terminates on a country-by-country basis on the last to occur of fifteen years from the date of the agreement (2018), the expiration of the last to expire Alkermes patent or the existence of a threshold level of competition in that country.

Other License Agreements

In addition to the material license and collaboration agreements described above, we have entered into numerous other license agreements to support our research and development programs. These other license agreements include the following:

Manufacturing and Supply

Inbrija (levodopa inhalation powder)

Chelsea Manufacturing Facility

All commercial supply of Inbrija is currently manufactured at Catalent’s Chelsea, Massachusetts manufacturing facility, which was transferred to Catalent in February 2021 in connection with our sale to Catalent of our Chelsea manufacturing operations. In connection with the sale, we entered into a long-term, global manufacturing services (supply) agreement with a Catalent affiliate pursuant to which they have agreed to manufacture Inbrija for us at the Chelsea facility. Under the supply agreement, which is further described below under Catalent Manufacturing Services Agreement, Catalent is our exclusive Inbrija supplier other than for sale in China.

Catalent may need expanded manufacturing capacity at the Chelsea facility to meet demand depending on the timing and extent of sales growth. In 2018, prior to the sale of the Chelsea manufacturing operations, we initiated a renovation and expansion of the Chelsea facility that increased the size of the facility from approximately 90,000 to approximately 95,000 square feet. The project added a new manufacturing production line for Inbrija that has greater capacity than the existing manufacturing line, and it has created additional warehousing space for manufactured product. Although the project was substantially completed in late 2019, the expansion does not yet have all of the approvals needed for use of the new production line for commercial manufacture, such as approvals from the FDA, Massachusetts state environmental permits, and approvals from other regulatory authorities. Also, manufacturing scale-up generally is subject to significant risks related to process development and manufacturing yields, which is especially true for the manufacture of a product such as Inbrija which involves a highly specialized spray drying and capsule filling process. Lastly, the expanded Chelsea facility will have to continue to comply with cGMP requirements, as described above in these risk factors, as well as other applicable environmental, safety, and other governmental permitting requirements.

If Catalent is unable to complete the expansion of the facility in a timely manner or there is unexpected demand for commercial quantities of Inbrija, there could be a supply shortage that would harm our commercialization of Inbrija. If we need the expanded capacity but Catalent is delayed in or prevented from completing the expansion and obtaining necessary regulatory approvals, we may need to seek another party to manufacturer additional Inbrija supply for us. As further discussed below, there can be no assurance that we could identify another third party that would be capable and willing to

16

manufacture for us on commercially reasonable terms, if at all, or that they could supply us with product in sufficient quantities on a timely basis to meet our needs. If we cannot obtain increased supply of Inbrija from expanded capacity at the Chelsea facility or engaging another third party manufacturer, we may not be able to meet demand for Inbrija and our ability to commercialize Inbrija could be harmed. Also, even if we do obtain Inbrija from another supplier, we may be unable to offset the costs of alternate supply against our minimum purchase commitments under the Catalent manufacturing services agreement, as further described below.

Furthermore, if Catalent were to lose the use of the facility or equipment, the manufacturing facility and manufacturing equipment would be difficult to replace and could require substantial replacement lead time and substantial additional funds. The facility may be affected by natural disasters, such as floods or fire, or Catalent may lose the use of the facility due to manufacturing issues that arise, such as contamination or regulatory concerns following a regulatory inspection of the facility. Catalent may also unexpectedly experience manufacturing issues as the unintended result of activities occurring at the facility unrelated to Inbrija manufacture. In the event of a loss of the use of all or a portion of the facility or equipment for the reasons stated above or any other reason, Catalent would be unable to manufacture Inbrija until such time as the facility or equipment could be repaired or rebuilt or they are able to address other manufacturing issues at the facility. Any such interruptions in their ability to manufacture Inbrija would harm our business. Even if Catalent does not suffer a loss of the facility or equipment within the facility, manufacturing operations can experience intermittent interruptions due to the need for routine or unexpected maintenance, inspection and repairs of the facility or the equipment, and, depending on their frequency and duration, these intermittent interruptions could also harm our business.

We do not currently have back-up manufacturing capability at another facility and there are only limited third party manufacturers that we believe would be capable of manufacturing Inbrija or other ARCUS inhaled therapeutic products or product candidates. If the need arises to obtain supply from another third party manufacturer, there can be no assurance that we could identify a third party that would be capable and willing to manufacture for us on commercially reasonable terms, if at all, or that they could supply us in sufficient quantities on a timely basis to meet our needs. Engaging a third party manufacturer to supply ARCUS products or product candidates would likely be a lengthy process due to the complexity and substantial regulation of the manufacturing processes involved. Also, engaging a third party would require the sharing of proprietary information, which increases the risk of unauthorized use or disclosure of that information and potential harm to our business for which we may not have an adequate remedy. If we are successful in engaging a third party manufacturer, they may not perform their obligations to us and/or they may be unable or unwilling to establish or increase production capacity commensurate with our needs. Also, third party manufacturers and suppliers are subject to their own operational and financial risks that are outside of our control, including macro-economic conditions that may cause them to suffer liquidity or operational problems and that could interfere with their business operations.

Catalent Manufacturing Services Agreement

We sold our Chelsea manufacturing operations to Catalent Pharma Solutions in February 2021. In connection with the sale, we entered into a long-term, global manufacturing services (supply) agreement with a Catalent affiliate pursuant to which they have agreed to manufacture Inbrija for us at the Chelsea facility. The manufacturing services agreement provides that Catalent will manufacture Inbrija (levodopa inhalation powder), to our specifications, and we will purchase Inbrija exclusively from Catalent during the term of the manufacturing services agreement; provided that such exclusivity requirement will not apply to Inbrija intended for sale in China.

The manufacturing services agreement, unless earlier terminated, will continue until December 31, 2030, and will be automatically extended for successive two-year periods unless either we or Catalent provides the other party with at least 18-months’ prior written notice of non-renewal. Either party may terminate the manufacturing services by written notice under certain circumstances, including material breach by the other party (subject to specified cure periods) or the insolvency of the other party. We may also terminate the manufacturing services agreement upon certain specified regulatory events and for convenience upon 180 days’ prior written notice, subject to payment of a specified substantial termination fee.

Under the manufacturing services agreement, we agreed to purchase from Catalent at least $16 million of Product in 2021 (pro-rated for a partial year) and $18 million of Product from 2022 through 2030 (and an additional amount in the last year in the case of such a proration), subject to reduction in certain cases. We are obligated to provide Catalent with a rolling 24-month forecast of production requirements, a portion of which will be considered a binding, firm order by us. Catalent is required to reserve sufficient capacity for the manufacture of a specified amount of Inbrija per year, with such capacity reservation to be reviewed on an annual basis.

17

In addition, the manufacturing services agreement grants to Catalent a non-exclusive, paid-up, royalty-free, non-transferrable, non-assignable, non-sublicensable license to certain of our intellectual property in order to enable the manufacture of Inbrija. Catalent has granted to us a worldwide, perpetual, irrevocable, non-exclusive, paid-up, royalty-free, assignable and sublicensable license to certain of its intellectual property as reasonably necessary to allow us to commercialize Inbrija.

The manufacturing services agreement contains customary representations, warranties and covenants, including with respect to the ownership of any intellectual property created pursuant to the manufacturing services agreement, as well as provisions relating to ordering, payment and shipping terms, regulatory matters, reporting obligations, indemnity, confidentiality and other matters.

Currently, we are not investing in any research and development programs pending further progress with the Inbrija launch. However, should we decide in the future to make investments in any ARCUS development program, we would be reliant on Catalent for the manufacture of product for that program. The manufacturing services agreement does not provide for the terms and conditions under which Catalent would supply any product or product candidate other than Inbrija. We would be unable to advance the development of any ARCUS inhaled therapeutic candidate unless Catalent is willing to manufacture the candidate for us on commercially reasonable terms.

Supply of Inbrija Components

Catalent, as our Inbrija supplier, is responsible for all Inbrija components other than the inhaler device and levodopa, or L-dopa, the active pharmaceutical ingredient, or API, in Inbrija. We have relied, and we expect to continue relying, on single third-parties to supply the inhaler and levodopa. We do not control how Catalent sources the other Inbrija components. Also, we rely on a single third party to package Inbrija kits after they are manufactured. Any failure or delay by a third party manufacturer, packager or supplier may delay or impair our ability to meet demand for Inbrija and could delay, prevent or impair our commercialization of Inbrija or to complete any future clinical studies that may be needed.

Although in some cases we have contracts for these requirements, we cannot be certain that those contracts will be renewed on commercially reasonable terms, if at all. We do not have contracts with the supplier of the API used in the manufacture of Inbrija, which exposes us to the risk that they could discontinue supply at any time. Manufacturers, packagers or suppliers may choose not to conduct business with us at all, or may choose to discontinue doing business with us, for example if they determine that our particular business requirements would be unprofitable or otherwise not appropriate for their business. We do not control how Catalent sources the other components of Inbrija, and our business could similarly be exposed to risk if and to the extent they rely on single source suppliers or do not have supply contracts.

Our proprietary Inbrija inhalers are manufactured using standard manufacturing processes and are shipped fully assembled to us. We own the molds and design history files for the inhalers. We currently source our proprietary Inbrija inhalers from a single third party plastic molding manufacturer for the Inbrija inhalers. Our reliance on a single third party for the manufacture of inhalers increases the risk that we will not have sufficient quantities of our inhalers or will not be able to obtain such quantities at an acceptable cost or quality, which could harm our commercialization of Inbrija. If the inhaler supplier fails to provide sufficient inhaler supply, we would need enter into alternative arrangements with a different suppler. Transition to a new inhaler supplier would be a lengthy and complex process. Among other things, we would have to revalidate the molding and assembly processes pursuant to FDA requirements and we would have to ensure that inhalers manufactured by the new supplier adhere to other applicable regulatory requirements.

All other raw materials used for Inbrija manufacture are standard in pharmaceutical production.

Ampyra

We are party to a September 2003 agreement with Elan (now Alkermes, following Alkermes’ 2011 acquisition of Elan’s Drug Technologies business) for our clinical and commercial supply of Ampyra. Under that agreement, we are required to purchase at least 75% of our annual commercial requirements of Ampyra from Alkermes unless Alkermes is unable or unwilling to meet our requirements. In addition, the agreement also obligates us to make compensatory payments if we do not purchase 100% of our requirements from Alkermes.

As permitted by our agreement with Alkermes, we have designated Patheon, Inc. as a second manufacturing source of Ampyra. In connection with that designation, we entered into a manufacturing agreement with Patheon, and Alkermes

18

assisted us in transferring manufacturing technology to Patheon. We and Alkermes have agreed that we may purchase up to 25% of our annual requirements from Patheon if we make compensatory payments to Alkermes. In addition, Patheon may supply us with Ampyra if Alkermes is unable or unwilling to meet our requirements.

Under a Consent Agreement among Elan (now Alkermes, following Alkermes’ acquisition of Elan’s Drug Technologies business), Biogen and us, Alkermes consented to our sublicense of our rights under our agreements with Alkermes to Biogen. The three parties agreed to set up a committee to coordinate activities under these agreements with respect to the development, supply and commercialization of the licensed products for Biogen's territory. The Consent Agreement also amended our agreements with Alkermes by, among other things, permitting us to allow Biogen to grant sublicenses to certain unaffiliated distributors, permitting us to allow Biogen to package the licensed products and to work directly with Alkermes with respect to certain supply-related activities, and requiring Alkermes to facilitate the qualification of an alternate supplier of the licensed products under certain circumstances.

We and Alkermes rely on a single third party manufacturer to supply dalfampridine, the active pharmaceutical ingredient, or API, in Ampyra, and also on a single supplier for a critical excipient used in the manufacture of Ampyra. We also rely on a single third party to package Ampyra. If these companies experience any disruption in their operations, our supply of Ampyra could be delayed or interrupted until the problem is solved or we locate another source of supply or another packager, which may not be available. We may not be able to enter into alternative supply or packaging arrangements on terms that are commercially reasonable, if at all. Any new supplier or packager would also be required to qualify under applicable regulatory requirements. Because of these and other factors, we could experience substantial delays before we are able to obtain qualified replacement products or services from any new supplier or packager.

Also, under our supply agreement with Alkermes, we provide Alkermes with monthly written 18-month forecasts and with annual written five-year forecasts for our supply requirements of Ampyra. In each of the three months for Ampyra following the submission of our written 18-month forecast, we are obligated to purchase the quantity specified in the forecast, even if our actual requirements are greater or less. Given the introduction of generic competition to Ampyra in the market, it may be difficult to forecast the level of supply needed to satisfy our requirements in the future.

Intellectual Property

We have patent portfolios relating to: Inbrija (levodopa inhalation powder); Ampyra/aminopyridines; the ARCUS drug delivery technology; cimaglermin alfa/neuregulins; and remyelinating antibodies/antibodies relating to nervous system disorders. These portfolios are composed of both our own and in-licensed patents and patent applications. Our intellectual property also includes copyrights, confidential and trade secret information as well as a portfolio of trademarks.

The intellectual property relating to our programs is owned or licensed either directly by Acorda or indirectly through a subsidiary, including for example our Civitas Therapeutics, Inc. subsidiary. Throughout this report, we may refer to any and all such intellectual property, and the corresponding research and development programs as, “our” or “Acorda’s” programs.

Inbrija (levodopa inhalation powder) and ARCUS Development Programs

The intellectual property portfolio that we acquired with Civitas has over 100 issued U.S. and foreign patents relating to Inbrija and the ARCUS drug delivery technology. This includes over 13 issued U.S. patents relating to Inbrija directed to compositions of the drug product, the inhaler, the capsule for the drug product, methods of delivery of L-dopa, and manufacturing processes. We have several patents listed in the Orange Book for Inbrija, including patents expiring between 2022 and 2032, and Inbrija is entitled to three years of new product exclusivity, through December 21, 2021, as posted in the Orange Book. We have patents in Europe for Inbrija expiring between 2022 and 2033. One of our European patents, EP 3090773B, has been opposed by an unnamed party. Inbrija also has 10 years of market exclusivity in Europe.

Ampyra/aminopyridines

There are no patents listed in the Orange Book for Ampyra. Ampyra became subject to competition from generic versions of Ampyra starting in late 2018 as a result of an adverse U.S. federal district court ruling that invalidated certain Ampyra Orange Book-listed patents.

There are two European patents, EP 1732548 and EP 2377536, with claims directed to use of a sustained release dalfampridine composition (known under the trade name Fampyra in the European Union) to increase walking speed in a

19

patient with multiple sclerosis. Both European patents are set to expire in 2025, absent any additional exclusivity granted based on regulatory review timelines. Nullity actions have been filed in Germany against both of the German national patents derived from EP 173548 and EP 2377536 by ratiopharm GmbH, a generic manufacturer affiliated with Teva. Fampyra also has 10 years of market exclusivity in the European Union that is set to expire in 2021.

We will vigorously defend our intellectual property rights.

Cimaglermin alfa/Neuregulins

Our neuregulin portfolio includes granted and pending U.S. and foreign patent applications directed to the use of neuregulins (e.g., GGF2) to treat peripheral nerve injury, non-acute central nervous system injuries and heart failure. We are also the exclusive licensee under a license agreement with Paion AG (formerly CeNeS Pharmaceuticals, plc), of patent rights related to specific uses of specific neuregulins.

Remyelinating Antibodies/Antibodies Related to Nervous System Disorders

Acorda is the exclusive licensee of a portfolio of patents and patent applications related to a series of remyelinating antibodies and their use discovered by scientists at the Mayo Clinic. This portfolio also includes granted and pending U.S. and foreign patent applications directed to additional antibodies and their use. With regard to remyelinating antibodies, the portfolio includes granted and pending U.S. and foreign patent applications for use in combination with the additional antibodies in treating cerebral ischemia or amyotrophic lateral sclerosis.

Trademarks

In addition to patents, our intellectual property portfolio includes registered trademarks, along with pending trademark applications. We own several registered trademarks in the U.S. and in other countries. These registered trademarks include, in the U.S., the marks “Acorda Therapeutics,” our stylized Acorda Therapeutics logo, “Biotie Therapies,” “Ampyra,” “Inbrija,” and “ARCUS.” We also have trademark registrations for “Fampyra” and “Inbrija” and pending trademark applications therefore, in numerous foreign jurisdictions. In addition, our trademark portfolio includes several trademark registrations and pending trademark applications for potential product names and for disease awareness activities.

Competition

The market for developing and marketing pharmaceutical products is highly competitive. Many biotechnology and pharmaceutical companies, as well as academic laboratories, are engaged in research, development and/or marketing of therapeutics for various neurological conditions, including Parkinson’s disease and multiple sclerosis. Many of our competitors have substantially greater financial, research and development, human and other resources than we do. Furthermore, many of these companies have significantly more experience than we do in preclinical testing, human clinical trials, regulatory approval procedures and sales and marketing.

Inbrija (levodopa inhalation powder)/Parkinson’s Disease

Inbrija competes against other therapies approved for intermittent, or as needed, use that aim to specifically address Parkinson’s disease symptoms. Apokyn, an injectable formulation of apomorphine, is approved for the treatment of OFF periods, also known as OFF episodes. Apokyn was approved for this use in the U.S. in 2004 and in Europe in 1993. Also, Sunovion Pharmaceuticals Inc. has developed a sublingual, or under the tongue, formulation of apomorphine branded as Kynmobi that is competitive with Inbrija. Sunovion received FDA approval for Kynmobi in May 2020 for the acute, intermittent treatment of OFF episodes, and Kymobi became available in the U.S. in September 2020.

The standard of care for the treatment of Parkinson’s disease is oral carbidopa/levodopa, but oral medication can be associated with wide variability in the timing and the amount of absorption and there are significant challenges in creating a regimen that consistently maintains therapeutic effects as Parkinson’s disease progresses. Inbrija may face competition from therapies that can limit the occurrence of OFF periods. Approaches to achieve consistent levodopa plasma concentrations include new formulations of carbidopa/levodopa, such as extended-release and intestinal infusions, and therapies that prolong the effect of levodopa. Amneal Pharmaceuticals, Inc. (formerly Impax Laboratories) markets RYTARY, an extended-release formulation of oral carbidopa/levodopa, and extended release formulations of oral and patch carbidopa/levodopa are being

20

developed by others including Intec Pharma and Mitsubishi Tanabe Pharma Corporation. Also, Abbvie Inc. has developed a continuous administration of a gel-containing levodopa through a tube that is surgically implanted into the intestine. This therapy, known as Duopa, has been approved by the FDA and is approved in the EU.

One or more of our competitors may utilize their expertise in pulmonary delivery of drugs to develop and obtain approval for pulmonary delivery products that may compete with Inbrija and any other of our other ARCUS drug delivery technology product candidates. These competitors may include smaller companies such as Alexza Pharmaceuticals, Inc., MannKind Corporation, Pulmatrix, Inc. and Vectura Group plc and larger companies such as Allergan, Inc., GlaxoSmithKline plc and Novartis AG, among others. If approved, our product candidates may face competition in the target commercial areas for these pulmonary delivery products. Also, we are aware that at least one company, Impel Neuropharma, is developing intranasally delivered levodopa therapies which, if approved, might compete with Inbrija.

Ampyra/MS

Ampyra became subject to competition from generic versions of Ampyra starting in late 2018 as a result of an adverse U.S. federal district court ruling that invalidated certain Ampyra Orange Book-listed patents. We have experienced a significant decline in Ampyra sales due to competition from several generic versions of Ampyra. Additional manufacturers may market generic versions of Ampyra, and we expect our Ampyra sales will continue to decline over time.

Current disease management approaches to MS are classified either as relapse management, disease course management, or symptom management approaches. For relapse management, the majority of neurologists treat sudden and severe relapses with a four-day course of intravenous high-dose corticosteroids. Many of these corticosteroids are available generically. For disease course management, there are a number of FDA-approved MS therapies that seek to modify the immune system. These treatments attempt to reduce the frequency and severity of exacerbations or slow the accumulation of physical disability for people with certain types of MS, though their precise mechanisms of action are not known. These products include Avonex, Tysabri, Plegridy and Tecfidera from Biogen, Betaseron from Bayer AG, Copaxone from Teva Pharmaceutical Industries, Ltd., Rebif from Merck Serono, Gilenya and Extavia from Novartis AG, Aubagio and Lemtrada from Genzyme Corporation (a Sanofi company), Glatopa from Sandoz International GmbH (a Novartis AG company), Zinbryta from Biogen and AbbieVie, Rituxan from F. Hoffman-La Roche AG, and Zeposia from BristolMyersSquibb.

Several biotechnology and pharmaceutical companies, as well as academic laboratories, are involved in research and/or product development for various neurological diseases, including MS. Other companies also have products in clinical development, including products approved for other indications in MS, to address improvement of walking ability in people with MS. This potential product may compete with Ampyra in the future. Furthermore, several companies are engaged in developing products that include novel immune system approaches and cell therapy approaches to remyelination for the treatment of people with MS. These programs are in early stages of development and may compete in the future with Ampyra or some of our product candidates. In addition, in certain circumstances, pharmacists are not prohibited from formulating certain drug compounds to fill prescriptions on an individual patient basis, which is referred to as compounding. We are aware that at present compounded dalfampridine is used by some people with MS and it is possible that some people will want to continue to use compounded formulations even though Ampyra and generic versions of Ampyra are commercially available.

Government Regulation

The FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries impose substantial requirements upon the preclinical testing, clinical development, manufacture, distribution and marketing of pharmaceutical products. These agencies and other federal, state and local entities regulate research and development activities and the testing, manufacture, quality control, safety, effectiveness, labeling, storage, distribution, record keeping, approval, advertising, sale, promotion, import and export of our products and product candidates.

FDA Regulation of Drugs and Drug Product Approval

In the U.S., Ampyra and our product candidates are regulated by the FDA as drugs but, as further discussed below, Inbrija is regulated as a combination product because it has both a drug and a device component. Drugs, biologics, and medical devices are regulated primarily under the Federal Food, Drug, and Cosmetic Act, as amended, the Public Health Service Act, as amended, and the regulations of the FDA. These products are also subject to other federal, state, and local statutes and regulations. Violations of regulatory requirements at any stage of development may result in various adverse

21

consequences, including the FDA's and other health authorities' delay in approving or refusal to approve a product. Violations of regulatory requirements also may result in enforcement actions, including withdrawal of approval, labeling restrictions, seizure of products, fines, injunctions and/or civil or criminal penalties. Similar civil or criminal penalties could be imposed by other government agencies or agencies of the states and localities in which our products are tested, manufactured, sold or distributed.

The process required by the FDA under these laws before our drug and biological product candidates may be marketed in the U.S. generally involves the following:

The research, development and approval process requires substantial time, effort, and financial resources, and we cannot be certain that any approval will be granted on a timely or commercially viable basis, if at all.

Preclinical studies include laboratory evaluation of the product candidate, its chemistry, formulation and stability, as well as animal studies to assess its safety and potential efficacy. The results of the preclinical studies, together with manufacturing information, analytical data and any available clinical data or literature must be submitted to the FDA as part of an IND application. The IND sponsor may initiate clinical trials 30 days after filing the IND application, unless the FDA, within the 30-day time period, raises concerns or questions about the conduct of the proposed clinical trial. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. Further, an independent Institutional Review Board, or IRB, charged with protecting the welfare of human subjects involved in research at each medical center proposing to conduct the clinical trials must review and approve any clinical trial before it commences at that center. The IRB(s) must continue to monitor the trial until its completion. Many studies also employ a data safety monitoring board, or DSMB, with experts who are otherwise independent of the conduct of the study and are given access to the unblinded study data periodically during the study to determine whether the study should be halted. For example, a DSMB might halt a study if an unacceptable safety issue emerges, or if the data showing the effectiveness of the study drug would make it unethical to continue giving patients placebo. Study subjects must provide informed consent before their participation in the research study.

Human clinical trials are typically conducted in three sequential phases, which may overlap:

22

In the case of product candidates for severe or life-threatening diseases, the initial human testing is often conducted in affected patients rather than in healthy volunteers. Since these patients already have the target condition, these clinical trials may provide initial evidence of efficacy traditionally obtained in Phase 2 clinical trials and thus these clinical trials are frequently referred to as Phase 1b clinical trials.

Before proceeding with a Phase 3 trial, sponsors may seek a written agreement from the FDA regarding the design and size of clinical trials intended to form the primary basis of an effectiveness claim. This is known as a Special Protocol Assessment, or SPA. SPAs help establish up front agreement with the FDA about the adequacy of the design of a clinical trial, but the agreement does not guarantee FDA approval even if the SPA is followed. For example, a substantial scientific issue essential to determining the safety or effectiveness of the drug could be identified after the testing has begun. In addition, even if an SPA remains in place and the trial meets its endpoints with statistical significance, the FDA could determine that the overall balance of risks and benefits for the product candidate is not adequate to support approval, or only justifies approval for a narrow set of clinical uses, or approval with restricted distribution or other burdensome post-approval requirements or limitations.

Federal law requires the submission of registry and results information for most clinical trials to a publicly available database at www.clinicaltrials.gov. These requirements generally do not apply to Phase 1 clinical trials.

U.S. law requires that trials conducted to support approval for product marketing be "adequate and well controlled." This entails a number of requirements, including that there is a clear statement of objectives and methods in the protocol, the study design permits a valid comparison with a control (e.g., a placebo, another drug already approved for the studied condition, or a non-concurrent control such as historical data), and that the statistical methods used to analyze the data are adequate to assess the effects of the drug. Studies must also be conducted in compliance with Good Clinical Practice, or GCP, requirements.

We cannot be certain that we will successfully complete Phase 1, Phase 2 or Phase 3 testing of our product candidates within any specific time period, if at all. Furthermore, the FDA, the IRBs or the DSMB may prevent clinical trials from beginning or may place clinical trials on hold or terminate them at any point in this process if, among other reasons, they conclude that study subjects or patients are being exposed to an unacceptable health risk.

In the U.S., for most drugs and biologics, the results of product development, preclinical studies and clinical trials must be submitted to the FDA for review and approval prior to marketing and commercial distribution of the product candidate. If the product candidate is regulated as a drug, an NDA must be submitted and approved before commercial marketing may begin. If the product candidate, such as an antibody, is regulated as a biologic, a BLA must be submitted and approved before commercial marketing may begin. The NDA or BLA must include a substantial amount of data and other information concerning safety and effectiveness (for a drug) and safety, purity and potency (for a biologic) of the compound from laboratory, animal and clinical testing, as well as data and information on manufacturing, product stability, and proposed product labeling.

Each domestic and foreign manufacturing establishment, including any contract manufacturers we may decide to use, must be listed in the NDA or BLA and must be registered with the FDA. The application will not be approved until the FDA conducts a manufacturing inspection, approves the applicable manufacturing process for the drug or biological product, and determines that the facility is in compliance with current Good Manufacturing Practice, or cGMP, requirements. If the manufacturing facilities and processes fail to pass the FDA inspection, we will not receive approval to market these products, or approval will likely be delayed until the manufacturing issues are resolved. The FDA may also inspect clinical trial sites and/or the clinical sponsor for compliance with Good Clinical Practice, or GCP. If the FDA determines that one or more of our clinical trials were not conducted in accordance with GCP, the agency may determine not to consider effectiveness data generated from such clinical trials in support of our applications for marketing approval.

Under the Prescription Drug User Fee Act, as amended, the FDA receives fees for reviewing an NDA or BLA and supplements thereto, as well as annual fees for commercial manufacturing establishments and for approved products. These fees could be significant.

Once an NDA or BLA is submitted for FDA approval, the FDA will accept the NDA or BLA for filing if deemed complete, thereby triggering substantive review of the application. The FDA can refuse to file any NDA or BLA that it deems incomplete or not properly reviewable. The FDA has established performance goals for the review of NDAs and BLAs: six months for priority applications and 10 months for regular applications, with two additional months added to each period for new molecular entities. However, the FDA is not legally required to complete its review within these periods and these

23

performance goals may change over time. Moreover, the outcome of the review, even if favorable, often is not an actual approval but an “action letter” or “complete response letter” that describes additional work that must be done before the application can be approved. This additional work could include substantial additional clinical trials. The FDA's review of an application may involve review and recommendations by an independent FDA advisory committee.

The FDA may deny an NDA or BLA if the applicable regulatory criteria are not satisfied or may require additional preclinical or clinical data. Even if such data are submitted, the FDA may ultimately decide that the NDA or BLA does not satisfy the criteria for approval. If the FDA approves a product, it will limit the approved therapeutic uses for the product as described in the product labeling, may require that contraindications or warning statements be included in the product labeling, may require that additional post-approval studies or clinical trials be conducted as a condition of the approval, may impose restrictions and conditions on product distribution, prescribing or dispensing in the form of a risk evaluation and mitigation strategy, or REMS, or may otherwise limit the scope of any approval. Under a REMS, the FDA may impose significant restrictions on distribution and use of a marketed product, may require the distribution of medication guides to patients and/or healthcare professionals or patient communication plans, and may impose a timetable for submission of assessments of the effectiveness of a REMS. Once issued, the FDA may withdraw product approval if compliance with regulatory standards is not maintained or if problems occur after the product reaches the market.

Satisfaction of the above FDA requirements or similar requirements of state, local and foreign regulatory agencies typically take several years or more and the actual time required may vary substantially, based upon the type, complexity and novelty of the product candidate. Government regulation may delay or prevent marketing of potential products for a considerable period of time or permanently and impose costly procedures upon our activities. Even if a product candidate receives regulatory approval, the approval may be significantly limited to specific indications. Further, even after regulatory approval is obtained, later discovery of previously unknown problems with a product may result in restrictions on the product, labeling changes or even complete withdrawal of the product from the market. Delays in obtaining, or failures to obtain and maintain, regulatory approvals for our products and product candidates would harm our business. Marketing our product candidates abroad will require similar regulatory approvals and is subject to similar risks. In addition, we cannot predict what adverse governmental regulations may arise from future U.S. or foreign governmental action.

Post-Approval Regulation

Any products manufactured or distributed in the U.S. by us pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including requirements relating to record-keeping, labeling, packaging, reporting of adverse experiences and other reporting, advertising and promotion, distribution, cGMPs, and import/export, as well as any other requirements imposed by the applicant’s NDA or BLA. The FDA's rules for advertising and promotion require, among other things, that our promotion be truthful, fairly balanced and adequately substantiated, and that our labeling bears adequate directions for all intended uses of the product. We must also submit appropriate new and supplemental applications and obtain FDA approval for certain changes to the approved product, product labeling or manufacturing process. On its own initiative, the FDA may require changes to the labeling of an approved drug, require post-approval studies or clinical trials, or impose a REMS post-approval if it becomes aware of new safety information that the agency believes impacts the drug’s safety profile. Drug manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMPs, which impose certain procedural and documentation requirements upon us and our third party manufacturers. Foreign drug manufacturers must comply with similar local requirements and may be subject to inspections by the FDA or local regulatory agencies. We cannot be certain that we or our present or future suppliers will be able to comply with cGMPs and other regulatory requirements. The FDA also enforces the requirements of the Prescription Drug Marketing Act, or PDMA, which, among other things, imposes various requirements in connection with the distribution of product samples to physicians.

In addition to inspections related to manufacturing, we are subject to periodic unannounced inspections by the FDA and other regulatory authorities related to the other regulatory requirements that apply to marketed drugs manufactured or distributed by us. The FDA also may conduct periodic inspections regarding our review and reporting of adverse events, or related to compliance with the requirements of the PDMA concerning the handling of drug samples. When the FDA conducts an inspection, the inspectors will identify any deficiencies they believe exist in the form of a notice of inspectional observations on FDA Form 483. The observations may be more or less significant. If we receive a notice of inspectional observations, we likely will be required to respond in writing, and may be required to undertake corrective and preventive actions in order to address the FDA's concerns. Failure to address the FDA’s concerns may result in the issuance of a warning letter or other enforcement or administrative actions.

24

We and our product candidates are also subject to a variety of state laws and regulations in those states or localities where they are or will be marketed, or where we may have operations. For example, we must comply with state laws that require the registration of manufacturers and wholesale distributors of pharmaceutical products in that state, including, in certain states, manufacturers and distributors who ship products into the state even if such manufacturers or distributors have no place of business within the state. Federal law and some states also impose requirements on manufacturers, distributors, and other trading partners that govern the introduction and movement of product through the supply chain, including requirements for the exchange of transaction documentation, development of systems capable of tracking and tracing product as it moves through the distribution chain, and responding to requests from trading partners and government agencies. Any applicable federal, state or local regulations may hinder our ability to market, or increase the cost of marketing, our products in those states or localities.

The FDA's policies may change and additional U.S. or foreign government laws and/or regulations may be enacted which could impose additional burdens or limitations on our ability to obtain approval of our product candidates or market our products after approval. Moreover, increased attention to the containment of healthcare costs in the U.S. and in foreign markets could result in government scrutiny or new regulations that could harm our business. For example, significant price increases in recent years by certain drug manufacturers have received considerable scrutiny from U.S. Congress, in some cases forcing those companies to dramatically reduce those prices. There continues to be political pressure at both the U.S. federal and state levels related to drug pricing and drug transparency that could result in legislative or administrative actions, such as the State of California’s passage of SB 17 in 2017, or at a minimum continued scrutiny. California SB 17, for example, put in place new state reporting and notification requirements for manufacturers related to drug pricing, which became effective January 1, 2018. In May 2018, the former Trump presidential administration issued "American Patients First," a multi-faceted blueprint to lower drug prices and subsequently took administrative steps to implement the blueprint, including through proposing sweeping demonstration projects aimed at putting downward pressure on drug prices. In addition, members of Congress have indicated an interest in legislative measures designed to lower drug costs. The new Biden administration has indicated that lowering prescription drug prices is a priority, but we do not yet know what steps the administration will take or whether such steps will be successful. We cannot predict the likelihood, nature or extent of adverse governmental regulation that might arise from future legislative or administrative action, either in the U.S. or abroad.

Generic Drugs, AB Ratings and Pharmacy Substitution

Generic drugs are approved through an abbreviated regulatory process, which differs in important ways from the process followed for innovative products. For generic versions of drugs subject to an NDA, an abbreviated new drug application, or ANDA, is filed with the FDA. The ANDA must seek approval of a product candidate that has the same active ingredient(s), dosage form, strength, route of administration, and conditions of use (labeling) as a so-called "reference listed drug" that has already been approved pursuant to a full NDA. Only limited exceptions exist to this ANDA sameness requirement, including certain limited variations approved by the FDA through a special suitability petition process. ANDA applicants are not required to submit clinical data to demonstrate safety and efficacy. Instead, the FDA relies on its findings of safety and effectiveness of the reference listed drug to approve the ANDA. As a result, the law requires the ANDA applicant submit only limited clinical data to demonstrate that the product covered by the ANDA is absorbed in the body at a rate and extent consistent with that of the reference listed drug. This is known as bioequivalence. In addition, the ANDA must contain information regarding the manufacturing processes and facilities that will be used to ensure product quality. It also must contain certifications with respect to all patents that are listed for the reference listed drug in the FDA’s publication, “Approved Drug Products with Therapeutic Equivalence Evaluations,” commonly known as the “Orange Book.”

Under the Federal Food, Drug, and Cosmetic Act, drugs that are new chemicals entities, or NCEs, are eligible for a five-year data exclusivity period. During this period, the FDA may not accept for review an ANDA submitted by another company that relies on any of the data submitted by the innovator company. This exclusivity period also applies to “505(b)(2)” applications, which are hybrid applications that rely in-part on pioneer data and in-part on new clinical data submitted to account for differences between the 505(b)(2) product and the reference listed drug. ANDA applicants and 505(b)(2) applicants must certify to all patents listed in the Orange Book for the reference listed drug (i.e., the innovator NDA). An ANDA (or 505(b)(2) application) may be submitted to FDA after four years if it contains a certification of patent invalidity or non-infringement to one of those listed patents. The statute also provides three years of data exclusivity for an NDA (or NDA supplement) that is not an NCE if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed essential to approval. During this period, the FDA will not approve an application filed by a third party for the protected conditions of use that relies on any of the data that was submitted by the innovator company. Neither exclusivity period blocks the approval of full applications (i.e., full NDAs) submitted to the FDA because full NDAs do not rely on a pioneer’s data.

25

Special procedures apply when an ANDA contains one or more certifications stating that a listed patent is invalid or not infringed. This is known as a “Paragraph IV” certification. If the owner of the patent or the NDA for the reference listed drug brings a patent infringement suit within a specified time after receiving notice of the Paragraph IV certification, an automatic stay bars FDA approval of the ANDA for 30 months, which period may be extended under certain circumstances. The length of the automatic stay depends on whether the FDA classifies the reference listed drug as an NCE, as follows:

If the stay is either lifted or expires and the FDA approves the ANDA, the generic manufacturer may decide to begin selling its product even if patent litigation is pending. However, if the generic manufacturer launches before patent litigation is resolved, the launch is at the risk of the generic manufacturer being later held liable for patent infringement damages.

Many states require or permit pharmacists to substitute generic equivalents for brand-name prescriptions unless the physician has prohibited substitution. Managed care organizations often urge physicians to prescribe drugs with generic equivalents, and to authorize substitution, as a means of controlling costs of prescriptions. They also may require lower copayments as an incentive to patients to ask for and accept generics.

While the question of substitutability is one of state law, most states look to the FDA to determine whether a generic is substitutable. The FDA lists therapeutic equivalence ratings in the “Orange Book.” In general, a generic drug that is listed in the Orange Book as therapeutically equivalent to the branded product will be substitutable under state law and, conversely, a generic drug that is not so listed will not be substitutable. Drug products that the FDA considers to be therapeutically equivalent to other drug products receive one of various types of “A” ratings. For example, solid oral dosage form drug products that are considered therapeutically equivalent are generally rated “AB” in the Orange Book, while therapeutically equivalent solutions and powders for aerosolization generally receive an “AB” or an “AN” rating depending on how bioequivalence was demonstrated.

To be considered therapeutically equivalent, a generic drug must first be a pharmaceutical equivalent of the branded drug. This means that the generic has the same active ingredient, dosage form, strength or concentration and route of administration as the branded drug. Tablets and capsules are currently considered different dosage forms that are pharmaceutical alternatives and therefore are not substitutable pharmaceutical equivalents. In addition to being pharmaceutical equivalents, therapeutic equivalents must be bioequivalent to their branded counterparts. Bioequivalence for this purpose is defined in the same manner as for ANDA approvals, and usually requires a showing of comparable rate and extent of absorption in a small human study.

The process described above is not applicable to drugs where the pioneer product was approved pursuant to a BLA, rather than an NDA. A separate process exists for follow-on versions of such products and is discussed in the section entitled “Biosimilars,” below.

Requirements Applicable to Medical Devices in the United States

The FDA regulates, among other things, the development, testing, manufacturing, labeling, safety, effectiveness, storage, record keeping, marketing, import, export, and distribution of medical devices. The level of regulation applied by the FDA generally depends on the class into which the medical device falls: Class I, II, or III. Class I medical devices present the lowest risk, and Class III medical devices present the highest risk. In general, the higher class of device, the greater the degree of regulatory control. All devices, for example, are subject to “General Controls,” which include:

26

Class II medical devices are subject to General Controls, but also Special Controls, including special labeling requirements, mandatory performance standards, additional post market surveillance, and specific FDA guidance. Most Class III medical devices are assessed individually through an extensive Premarket Review application, or PMA. As a result, although they are subject to General Controls, they generally are not subject to Special Controls. Instead, most Class III devices have additional requirements and conditions of use imposed on them through the individualized PMA review and approval process.

Although we do not manufacture or market stand-alone medical devices, Inbrija relies on a device component (the inhaler) to deliver drug product to patients. In general, the FDA regulates that type of product as a “combination product.” The FDA assigns combination products for review by the drug or device center based on a determination of the product’s “primary mode of action.” If the FDA determines that the product achieves its therapeutic effect through drug component, as was the case with Inbrija, it will be assigned to the Center for Drugs (CDER) or the Center for Biologics (CBER) for review and approval. By contrast, if the FDA determines that the device component is the primary mode of action, then the product will be reviewed and approved by the center for devices (CDRH). CDER is the lead review division for Inbrija. We anticipate that to the extent that any of our other pipeline products are regulated as combination products, the FDA likely will find that the primary mode of action is through the drug component, and therefore the product will be reviewed by CDER. In that case, however, CDER/CBER will consult with CDRH on the drug component and we will still have to comply with certain requirements applicable to medical devices.

Most Class I devices are exempt from the FDA premarket review or approval. With some exceptions, Class II devices may be marketed only if the FDA “clears” the medical device through the 510(k) process, which requires a company to show that the device is “substantially equivalent” to certain devices already on the market. Again with some exceptions, Class III devices are approved through a PMA, which generally requires an applicant to submit data from clinical trials that establish the safety and effectiveness of the device. Clinical data are sometimes required for a 510(k) application as well. Manufacturers conducting clinical trials with medical devices are subject to similar requirements as those conducting clinical trials with drugs or biologics. For example, a manufacturer must obtain an investigational device exemption, or IDE, to test a significant risk device in humans, must comply with GCPs, and must obtain IRB approval. Although Inbrija includes a medical device component (the inhaler), Inbrija is a combination product that was approved by CDER via an NDA and these medical device clearance/approval requirements are not applicable to Inbrija.

The FDA has broad post-market regulatory and enforcement powers with respect to medical devices, similar to those for drugs and biologics. For example, medical devices are subject to detailed manufacturing standards under the FDA’s quality systems regulations, or QSRs, and specific rules regarding labeling and promotion. Medical device manufacturers must also register their establishments and list their products with the FDA.

States also impose regulatory requirements on medical device manufacturers and distributors, including registration and record-keeping requirements. Failure to comply with the applicable federal and state medical device requirements could result in, among other things, refusal to approve or clear pending applications, withdrawal of an approval or clearance, warning letters, product recalls, product seizures, total or partial suspension of production, fines, refusals of government contracts, restitution, disgorgement, or other civil or criminal penalties.

Biosimilars

The Affordable Care Act amended the Public Health Service Act to authorize the FDA to approve “biosimilars” (follow-on versions of pioneer products approved pursuant to a BLA) via a separate, abbreviated pathway. Under this abbreviated pathway, the biosimilar applicant must demonstrate that its product is “highly similar” to the “reference product,” and that there are no “clinically meaningful differences” between the biosimilar and the reference product. Unlike ANDAs,

27

biosimilars are not, in general, automatically substitutable for the reference product at the pharmacy. Instead, the FDA must make a separate finding of “interchangeability.” To date, the trend in state law has been to permit or require substitution only of those biosimilars that have also been deemed by the FDA to be interchangeable.

The Affordable Care Act also established a period of 12 years of data exclusivity against biosimilars for reference products in order to preserve incentives for future innovation. Under this framework, data exclusivity protects the data in the BLA-holders’ regulatory application by prohibiting others, for a period of 12 years, from gaining FDA approval based in part on reliance on or reference to the reference product’s data in its approved BLA. In contrast to the provisions for NDAs, the biologics data exclusivity provisions do not change the duration of patents granted on biologic products, or otherwise create an “automatic stay” of FDA approval of a biosimilar. If our product candidates are approved as biologics, they may face significant competition from biosimilars in the future.

Foreign Regulation and Product Approval

Outside the U.S., our ability or the ability of one of our collaborators to market a product candidate is contingent upon receiving a marketing authorization from the appropriate regulatory authorities. The requirements governing the conduct of clinical trials, marketing authorization, pricing and reimbursement can vary widely from country to country. The foreign regulatory approval process involves risks very similar to those associated with FDA approval discussed above.

Within the European Union, or EU, it is possible to obtain marketing authorizations that enable an approved product to be marketed in the entire European Economic Area, or EEA, which is composed of the EU member states plus Iceland, Lichtenstein and Norway. This can be through the “centralized procedure” which is mandatory for certain products, including biotechnology and advanced therapy medicinal products, orphan medicines and new active substances for the treatment of acquired immune deficiency syndrome (AIDS), cancer, neurodegenerative disorder, diabetes, auto-immune diseases and other immune dysfunctions and viral diseases, or through the “mutual recognition” or “decentralized” procedure, which provides for the approval of a product by one or more member states based on an assessment of an application review performed by one or more other member states. The foreign regulatory approval process involves risks very similar to those associated with FDA approval discussed above.

On September 19, 2019, the European Commission granted a marketing authorization to Inbrija, for the intermittent treatment of episodic motor fluctuations (OFF episodes) in adult patients with Parkinson’s disease treated with a levodopa/dopa-decarboxylase inhibitor. This marketing authorization was granted through the centralized procedure and is therefore valid throughout the EEA. The marketing authorization is valid for five years and once renewed is usually valid for an unlimited period thereafter. If a product approved under the centralized procedure is not marketed in at least one EU member state within three years of the grant of the marketing authorization, the marketing authorization lapses under the EU’s sunset rules.

Products such as Inbrija that combine a drug and device co-packaged in a single presentation are regulated under the EU’s medicines rules and approved under a single marketing authorization. As part of the marketing authorization process, the applicant must demonstrate to EU regulators that the device component conforms with the essential legal requirements for medical devices under EU law and, accordingly, bears the CE-mark. Currently, the essential requirements are contained in the EU Medical Device (Directive 98/79/EC), or MDD. As of May 26, 2021, the Medical Device Directive will be repealed and replaced by the new EU Medical Device Regulation (Regulation (EU) 2017/745), or MDR, and the essential requirements for medical devices set out therein will apply from that date, subject to a transitional period. The transitional period applies to medical devices whose certificates of conformity were issued by a notified body under the MDD after May 25, 2017. The transitional period permits devices to be placed on the market under such circumstances until the sooner of (i) the date of expiry of the certificate; or (ii) a long stop date of May 27, 2024.

In the EU, innovator products, approved on the basis of a complete and independent data package are usually entitled to a total of 10 years of regulatory exclusivity from the date of first approval. This means that for a period of eight years, EU authorities may not accept marketing authorization applications that rely on the safety and efficacy data contained in the marketing authorization dossier of the innovator product. At the end of that period, generic applicants may file and authorities may review such applications. The innovator product is protected by a further two years of market exclusivity before any generic product may launch, such that the innovator product benefits from total regulatory exclusivity period of 10 years.

Inbrija received its EU marketing authorization on the basis of a complete and independent data package and therefore benefits from the 10-year regulatory exclusivity period described above (i.e., eight years of data exclusivity plus two additional years of market exclusivity).

28

The fact that a product benefits from regulatory exclusivity does not prevent competitors from obtaining a marketing authorization based on their own independently generated data. EU regulatory authorities have stated that they consider levodopa, which is the active substance contained in Inbrija, to be a “known active substance.” In principle, this means that generic competitors could – during Inbrija’s regulatory exclusivity period -- file and receive a marketing authorization referring, for example, to data from the dossiers of older, established products containing levodopa, supplemented with other data that the competitor generates itself (e.g., demonstrating the safety and efficacy of the inhaled dosage form).

As the marketing authorization holder for Inbrija in the EU, we are required to comply with a number of requirements applicable to the manufacturing, marketing, promotion and sale of the medicinal products. In particular, a marketing authorization holder’s obligations include complying with the EU’s pharmacovigilance or safety reporting rules. All marketing authorizations include a Risk Mitigation Plan, or RMP, describing the risk mitigation measures that a marketing authorization holder must put in place, including post-authorization obligations such as additional safety monitoring or the conduct of post-authorization safety studies. RMPs are intended to be updated throughout the lifetime of a medicine and marketing authorization holders are expected to submit updated RMPs as new information becomes available or at the request of EU regulatory authorities.

Other regulatory requirements relate, for example, to the manufacturing of products and active pharmaceutical ingredients in accordance with good manufacturing practice standards. The European Medicines Agency, or EMA, is responsible for coordinating inspections conducted by member state competent authorities to verify compliance with various aspects of the EU’s medicines rules. In respect of inspecting manufacturing sites, in July 2019 the EU and U.S. implemented a mutual recognition agreement, or MRA, under which EU and U.S. regulators will now rely on each other’s inspections for manufacturing sites for human medicines in their respective territories.

Non-compliance with EU requirements, particularly regarding safety monitoring or pharmacovigilance, can also result in the marketing authorization holder becoming subject to significant financial penalties. Inspections may be routine or triggered by issues arising during the assessment of the dossier or by other information, such as previous inspection experience. Inspections usually are requested during the initial review of a marketing authorization application, but could arise post-authorization. Regulatory authorities in the EU may suspend, revoke or vary a marketing authorization of a medicinal product if they consider that the product is harmful, lacks therapeutic efficacy, its risk-benefit balance is not favorable, its qualitative and quantitative composition is not as declared or for certain other reasons.

A marketing authorization holder may not delegate its ultimate legal responsibility for complying with its legal requirements nor any liability for failing to do so. However, the marketing authorization holder may delegate the performance of certain tasks to third parties, provided this is appropriately documented and managed. It is also possible to transfer a marketing authorization to a third party.

The EU’s medicines rules do not require the launch of a product in a particular member state. However, once a medicinal product is launched in a member state, the marketing authorization holder is under a legal obligation to take steps to ensure it meets demand for the product in that country. The EU’s medicines rules also contain so-called sunset clauses, which provide that a marketing authorization will cease to be valid if the product in question is not placed on the market in at least one jurisdiction in the EEA within three years of the grant of the marketing authorization.

As in the U.S., EU law and the regulatory systems in EU member states tightly regulate the advertising and promotion of medicinal products. Unlike in the U.S., EU law prohibits the advertising of prescription-only medicinal products (such as Inbrija) directly to patients or the general public. Advertising to healthcare professionals is permitted, provided certain conditions are met. Certain activities fall outside the scope of EU medicines advertising rules, such as direct responses to requests for information and the dissemination of factual, informative non-promotional announcements and reference material. All advertising for a medicine must be consistent with the product’s approved Summary of Product Characteristics, or SmPC, factual, accurate, balanced and non-misleading. Advertisements to healthcare professionals must adhere to certain specific requirements. For example, the provision of inducements to healthcare professionals designed to promote the prescription, supply, sale or consumption of medicinal products is not permitted, and some member states have expanded this prohibition to cover inducements to healthcare organizations. The promotion of a medicine pre-approval is prohibited as is the promotion of off-label use and promotion that is inconsistent with the product’s SmPC. While EU law provides a framework for medicines advertising rules, national laws, guidance and regulatory codes (or self-regulatory codes) can lead to differences in approach at the national level.

29

Other Regulations

In the U.S., the research, manufacturing, distribution, sale, and promotion of drug and biological products, as well as medical devices, are potentially subject to regulation and oversight by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare & Medicaid Services (CMS), other divisions of the U.S. Department of Health and Human Services (e.g., the Office of Inspector General), the U.S. Department of Justice and individual U.S. Attorney offices within the Department of Justice, the Drug Enforcement Administration (DEA), and state and local governments. Controlled substances that are scheduled by the DEA are subject to additional regulatory requirements including, among other things, special security and handling requirements, and potential restrictions on distribution, sales, marketing. Sales, marketing, scientific/educational grant programs and other Acorda interactions with healthcare professionals, must comply with the anti-kickback and fraud and abuse provisions of the Social Security Act and the False Claims Act, and may be affected by the privacy provisions of the Health Insurance Portability and Accountability Act, or HIPAA, and similar state laws. Pricing and rebate programs must comply with the Medicaid rebate requirements of the Omnibus Budget Reconciliation Act of 1990, and/or the Veterans Health Care Act of 1992. For products to be covered by Medicaid, drug manufacturers must enter into a rebate agreement with the Secretary of Health and Human Services on behalf of the states and must regularly submit certain pricing information to CMS. Under the VHCA, we are required to offer certain drugs at a reduced price to a number of federal agencies including the Veterans Administration and the Department of Defense, or DOD, the Public Health Service and certain private Public Health Service designated entities in order to participate in other federal health care programs including Medicare and Medicaid. In addition, discounted prices must also be offered for certain DOD purchases for its TRICARE retail pharmacy program via a rebate system. Participation under the VHCA requires submission of pricing data and calculation of discounts and rebates pursuant to complex statutory formulas, as well as the entry into government procurement contracts governed by the Federal Acquisition Regulations.

Several states have enacted legislation requiring pharmaceutical companies to establish marketing compliance programs, file periodic reports with the state, make periodic disclosures on sales, marketing, pricing, and other activities, and/or register their sales representatives, and to prohibit certain other sales and marketing practices. In addition, our activities are potentially subject to federal and state consumer protection and unfair competition laws.

Under the Sunshine Act provisions of the Affordable Care Act (ACA), pharmaceutical manufacturers are subject to federal reporting requirements with regard to payments or other transfers of value made to physicians and teaching hospitals. Reports submitted under these requirements are placed on a public database. Pharmaceutical manufacturers are required to submit reports to CMS annually. Beginning with reports submitted in 2022 (for calendar year 2021), the Sunshine Act will also apply to payments to physician assistants and advance practice nurses. Similarly, the ACA requires pharmaceutical manufacturers to annually report to FDA samples of prescription drugs requested by and distributed to healthcare providers. The law does not state whether these sample disclosures will be made publicly available, and the FDA has not provided any additional guidance as to how the data will be used.

Our research and development and manufacturing activities are subject to numerous environmental, health and safety laws and regulations, including, among other matters, those governing laboratory procedures and the use, generation, manufacture, distribution, storage, handling, treatment, remediation and disposal of hazardous substances; the exposure of persons to hazardous substances; the release of pollutants into the air and bodies of water; and the general health, safety and welfare of employees and members of the public. Our research and development and manufacturing activities and the activities of our third party manufacturers involve the use of hazardous substances, and the risk of injury, contamination or noncompliance with the applicable environmental, health and safety requirements cannot be eliminated. We may incur significant costs to comply with such laws and regulations now or in the future. Although compliance with such laws and regulations has not had a material effect on our capital expenditures, earnings or competitive position, environmental, health and safety laws and regulations have tended to become increasingly stringent and, to the extent legal or regulatory changes occur in the future, they could result in, among other things, increased costs to us.

Reimbursement and Pricing Controls

In many of markets where we or a collaborator markets or may potentially market one of our approved products, the prices of pharmaceutical products are subject to direct price controls, by law, and to drug reimbursement programs with varying price control mechanisms.

In the U.S., there has been an increased focus on drug pricing in recent years. Although there are currently no direct government price controls over private sector purchases in the U.S., federal legislation requires pharmaceutical manufacturers to pay prescribed rebates on certain drugs to certain public healthcare programs, such as Medicaid, in order for the drugs to

30

be eligible for reimbursement under those programs. Various states have adopted further mechanisms under Medicaid and other programs that seek to control drug prices, including by disfavoring certain higher priced drugs and by seeking supplemental rebates from manufacturers. Managed care has also become a potent force in the marketplace that increases downward pressure on the prices of pharmaceutical products. Recent heightened scrutiny of the prices of several drug products have led to numerous other proposals, at both the federal and state level, to address perceived issues related to drug pricing and drug transparency. Several other states have adopted or are considering adopting laws that require pharmaceutical companies to provide notice prior to raising pricing and other information related to price increases. In May 2018, the former Trump presidential administration issued "American Patients First," a multi-faceted blueprint to lower drug prices and subsequently took administrative steps to implement the blueprint, including through proposing sweeping demonstration projects aimed at putting downward pressure on drug prices. On November 20, 2020, CMS issued an interim final rule through the CMS Innovation Center whereby Medicare Part B reimbursement for “certain high-cost prescriptions drugs” would be no more than most-favored-nation price (i.e., the lowest price) after adjustments, for a pharmaceutical product that the drug manufacturer sells in a member country of the Organization for Economic Cooperation and Development that has a comparable per-capita gross domestic product. On December 28, 2020, the United States District Court in Northern California issued a nationwide preliminary injunction against implementation of the interim final rule. In addition, members of the U.S. Congress have indicated an interest in legislative measures designed to lower drug costs. The new Biden administration has indicted that lowering prescription drug prices is a priority, but we do not yet know what steps the administration will take or whether such steps will be successful.

Under the reimbursement methodology set forth in the Medicare Modernization Act, or MMA, physicians are reimbursed for drugs they administer to Medicare beneficiaries based on a product's "average sales price," or ASP. This ASP-based reimbursement methodology has generally led to lower reimbursement levels. The MMA also established the Medicare Part D outpatient prescription drug benefit, which is provided primarily through private entities that attempt to negotiate price concessions from pharmaceutical manufacturers. The ACA, as amended, requires drug manufacturers to provide a 70% discount on prescriptions for branded products filled while the beneficiary is in the Medicare Part D coverage gap, also known as the “donut hole.”

The Deficit Reduction Act of 2005 resulted in changes to the way average manufacturer price, or AMP, and best price are reported to the government and the formula for calculating required Medicaid rebates. The ACA increased the minimum basic Medicaid rebate for branded prescription drugs to 23.1% and requires pharmaceutical manufacturers to pay states rebates on prescription drugs dispensed to Medicaid managed care enrollees. In addition, the ACA increased the additional Medicaid rebate on “line extensions” (such as extended release formulations) of solid oral dosage forms of branded products, revised the definition of AMP by changing the classes of purchasers included in the calculation, and expanded the entities eligible for discounts under a statutory program available to entities identified under Section 340B of the Public Health Service Act.

The ACA imposes a significant annual fee on companies that manufacture or import branded prescription drug products. The fee (which is not deductible for federal income tax purposes) is based on the manufacturer’s market share of sales of branded drugs and biologics (excluding orphan drugs) to, or pursuant to coverage under, specified U.S. government programs. The ACA also contains a number of provisions, including provisions governing the way that healthcare is financed by both governmental and private insurers, enrollment in federal healthcare programs, reimbursement changes, increased funding for comparative effectiveness research for use in the healthcare industry, and enhancements to fraud and abuse requirements and enforcement, that will affect existing government healthcare programs and will result in the development of new programs.

In December 2017, portions of the ACA dealing with the individual mandate insurance requirement were effectively repealed by the Tax Cuts and Jobs Act of 2017, and other aspects of the ACA may be altered or repealed by future legislation. In December 2018, a U.S. federal district court judge in Texas found the ACA’s individual mandate to be unconstitutional and therefore the entire law to be invalid. In December 2019, the U.S. Court of Appeals for the Fifth Circuit affirmed the ruling regarding the individual mandate, but remanded the case to the district court for additional analysis of the question of severability and whether portions of the law remain invalid. The case is currently under consideration by the U.S. Supreme Court and a decision is expected by Summer 2021. Public and private healthcare payers control costs and influence drug pricing through a variety of mechanisms, including through negotiating discounts with the manufacturers and through the use of tiered formularies and other mechanisms that provide preferential access to certain drugs over others within a therapeutic class. Payers also set other criteria to govern the uses of a drug that will be deemed medically appropriate and therefore reimbursed or otherwise covered. In particular, many public and private healthcare payers limit reimbursement and coverage to the uses of a drug that are either approved by the FDA and/or appear in a recognized drug compendium. Drug compendia are publications that summarize the available medical evidence for particular drug products and identify which

31

uses of a drug are supported or not supported by the available evidence, whether or not such uses have been approved by the FDA.

Different pricing and reimbursement schemes exist in other countries. There is extensive regulation of pharmaceutical pricing and reimbursement through health systems that fund a large part of the cost of such products to consumers. The grant of a marketing authorization in many jurisdictions does not necessarily guarantee that a product will be reimbursed in a particular jurisdiction. The approach taken varies by jurisdiction and in most cases a separate reimbursement approval is required. Some jurisdictions operate positive and/or negative list systems under which products may only be marketed once a reimbursement price has been agreed. Other member states allow companies to fix their own prices for medicines, but monitor and control company profits and may limit or restrict reimbursement based on the results of health economic assessments. Others control the price of pharmaceutical products through reference pricing approaches where the reimbursement price is determined by the price in other jurisdictions. The downward pressure on healthcare costs in general, particularly prescription drugs, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products, as exemplified by the National Institute for Health and Care Excellence, or NICE, in the United Kingdom which evaluates the data supporting new medicines and passes reimbursement recommendations to the government. In addition, in some countries cross-border imports from low-priced markets (parallel imports) exert commercial pressure on pricing within a country.

You should carefully consider the risks described below, in addition to the other information contained in this annual report, before making an investment decision. Our business, financial condition or results of operations could be harmed by any of these risks. The risks and uncertainties described below are not the only ones we face. Additional risks not presently known to us or other factors not perceived by us to present significant risks to our business at this time also may impair our business operations.

32

Risk Factors Summary

An investment in our securities is subject to various risks, the most significant of which are summarized below.

33

Risks related to our business

We have a history of operating losses and may not be able to achieve or sustain profitability in the future; we are substantially dependent on our ability to successfully market and sell Inbrija (levodopa inhalation powder).

As of December 31, 2020, we had an accumulated deficit of approximately $766.4 million. We had a net loss of $99.6 million for the year ended December 31, 2020. Since 2010, we have been highly dependent on sales of Ampyra in the U.S. However, Ampyra became subject to competition from generic versions of Ampyra starting in late 2018 as a result of an adverse U.S. federal district court ruling that invalidated certain Ampyra Orange Book-listed patents. We have experienced a significant decline in Ampyra sales due to competition from several generic versions of Ampyra. Additional manufacturers may market generic versions of Ampyra, and we expect our Ampyra sales will continue to decline over time.

Our prospects for achieving and sustaining profitability in the future will depend primarily on how successful we are in increasing Inbrija sales in the U.S. and establishing partnerships to sell Inbrija in the EU and other territories outside the U.S., as well as the extent and timing of continuing Ampyra sales declines due to generic competition. If we are not successful in executing our business plan, we may not achieve or sustain profitability and even if we do so, we may not meet sales expectations. Also, even if we are successful in executing our business plan, our ability to achieve and sustain profitability in the future will also depend on our ability to manage our operating costs, and profitability may fluctuate from period to period due to our level of investments in sales and marketing, research and development, and product and product candidate acquisitions.

We may not have sufficient cash flow from our business to continue to sufficiently fund our operations and pay our substantial debt

We will need to expend substantial resources for commercialization of our marketed products, including costs associated with the commercialization of Inbrija. In addition, our ability to make scheduled payments of the principal of, to pay interest on, or to refinance our indebtedness, including our convertible senior secured notes due 2024 depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to support our operations and service our debt and make necessary capital expenditures. Also, our research and development programs will not generate any revenues for

34

the foreseeable future, if ever, because they are all in early stages, pharmaceutical development is subject to numerous risks including those described elsewhere in these risk factors, and generally we have discontinued funding our research and development pending additional progress with the Inbrija commercial launch in the U.S.

Our ability to meet our future operating requirements, repay our liabilities, and meet our other obligations are dependent upon a number of factors, including our ability to generate cash from product sales, reduce planned expenditures, and obtain additional financing. If we are unable to generate sufficient cash flow from the sale of our products, we will be required to adopt one or more alternatives, subject to the restrictions contained in the indenture governing our convertible senior secured notes due 2024, such as further reducing expenses, selling assets, restructuring debt, or obtaining additional equity capital on terms that may be onerous and which are likely to be highly dilutive. Also, our ability to raise additional capital and repay or restructure our indebtedness will depend on the capital markets and our financial condition at such time, among other factors. In addition, financing may not be available when needed, at all, on terms acceptable to us or in accordance with the restrictions described above. As a result of these factors, we may not be able to engage in any of the alternative activities, or engage in such activities on desirable terms, which could harm our business, financial condition and results of operations, as well as result in a default on our debt obligations. If we are unable to take these actions, we may be forced to significantly alter our business strategy, substantially curtail our current operations, or cease operations altogether.

Our most recent restructuring and associated organizational changes may not adequately reduce our expenses, may lead to additional workforce attrition, and may cause operational disruptions.

In January 2021, we implemented a corporate restructuring to reduce costs and focus our resources on Inbrija (levodopa inhalation powder). As part of this restructuring, we reduced headcount by approximately 16% through a reduction in force (excluding employees that transferred to Catalent Pharma Solutions in connection with the completed sale of our Chelsea, Massachusetts manufacturing operations). Further restructuring activities may be required in the future, depending in particular on the rate of decline in our sales of Ampyra due to generic competition and whether we are able to sufficiently increase sales of Inbrija. Our restructuring may have other unintended consequences as well, including, for example, making it more difficult for us to attract and retain highly skilled personnel in a competitive environment (particularly given that this was our third corporate restructuring since 2017). We may also experience operational disruptions from our reduction in personnel. The loss of key personnel could disrupt our operations, and sales force attrition could harm our ability to market and sell Inbrija and Ampyra. We have recently experienced workforce attrition in various functions across our business, and we may not be able to adjust our operations in response to prevent disruption to our business.

Operating our business and servicing our debt requires a significant amount of cash, and we may need to obtain additional funding in the future if we do not have sufficient cash flow from our business to continue to sufficiently fund our operations and pay our substantial debt.

We will need to expend substantial resources for commercialization of our marketed products, including costs associated with the commercialization of Inbrija. In addition, our ability to make scheduled payments of the principal of, to pay interest on, or to refinance our indebtedness, including our convertible senior secured notes due 2024 depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to support our operations and service our debt and make necessary capital expenditures. Also, our research and development programs will not generate any revenues for the foreseeable future, if ever, because they are all in early stages, pharmaceutical development is subject to numerous risks including those described elsewhere in these risk factors, and generally we have discontinued funding our research and development pending additional progress with the Inbrija commercial launch in the U.S. If we are unable to generate sufficient cash flow from the sale of our products, we may be required to adopt one or more alternatives, subject to the restrictions contained in the indenture governing our convertible senior secured notes due 2024, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous and which are likely to be highly dilutive. Our ability to fund our operations and refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could harm our business, financial condition and results of operations, as well as result in a default on our debt obligations.

35

We may not have the ability to raise the funds necessary to settle conversions of our convertible notes or to repurchase notes upon a fundamental change.

Holders of both our convertible senior secured notes due 2024 and the remaining portion of our convertible senior notes due 2021 have the right to require us to repurchase their notes upon the occurrence of a fundamental change at a repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any. This use of cash may have a material adverse effect on our liquidity. Furthermore, we may not have enough available cash or be able to obtain financing at the time we are required to make cash payments with respect to either series of notes. In addition, our ability to repurchase the notes or to pay cash upon conversion of the notes may be limited by law, regulatory authority or agreements governing our future indebtedness. Our failure to repurchase notes at a time when the repurchase is required by the applicable indenture pursuant to which the notes were issued or to make cash payments to settle conversions or make interest payments (including make-whole interest payments on the 2024 notes) as required by the applicable indenture, would constitute a default under the applicable indenture.

The indenture governing our convertible senior secured notes due 2024 contains restrictions that may make it more difficult to execute our strategy or to effectively compete.

Subject to certain exceptions and qualifications, the indenture governing our convertible senior secured notes due 2024 restricts our ability and the ability of certain of our subsidiaries to, among other things, (i) pay dividends or make other payments or distributions on capital stock, or purchase, redeem, defease or otherwise acquire or retire for value any capital stock, (ii) make certain investments, (iii) incur indebtedness or issue preferred stock, other than certain forms of permitted debt, which includes, among other items, indebtedness incurred to refinance our convertible senior notes, (iv) create liens on assets, (v) sell assets, (vi) enter into certain transactions with affiliates or (vii) merge, consolidate or sell all or substantially all assets. The indenture also requires us to make an offer to repurchase the convertible senior secured notes due 2024 upon the occurrence of certain asset sales. These restrictions may make it difficult to successfully execute our business strategy or effectively compete with companies that are not similarly restricted.

An event of default under the indenture governing our convertible senior secured notes due 2024 could adversely affect our liquidity and our ability to retain title to our assets, including our intellectual property.

The indenture governing our convertible senior secured notes due 2024 provides that a number of events will constitute an event of default, including, among other things, (i) a failure to pay interest for 30 days, (ii) failure to pay the convertible senior secured notes when due at maturity, upon any required repurchase, upon declaration of acceleration or otherwise, (iii) failure to convert the convertible senior secured notes in accordance with the Indenture and the failure continues for five business days, (iv) not issuing certain notices required by the notes indenture within a timely manner, (v) failure to comply with the other covenants or agreements in the notes indenture for 60 days following the receipt of a notice of non-compliance, (vi) a default or other failure by us to make required payments under our other indebtedness or certain subsidiaries having an outstanding principal amount of $30.0 million or more, (vii) failure by us or certain subsidiaries to pay final judgments aggregating in excess of $30.0 million, (viii) certain events of bankruptcy or insolvency and (ix) the commercial launch in the U.S. of a product determined by the FDA to be bioequivalent to Inbrija.

In the case of an event of default arising from certain events of bankruptcy or insolvency with respect to us, all outstanding convertible senior secured notes due 2024 will become due and payable immediately without further action or notice. If any other event of default occurs and is continuing, the trustee or the holders of at least 25% in aggregate principal amount of the then outstanding convertible senior secured notes due 2024 may declare all the notes to be due and payable immediately. Such acceleration of our debt could have a material adverse effect on our liquidity if we are unable to negotiate mutually acceptable terms with the holders of the convertible senior secured notes due 2024 or if alternate funding is not available to us. Furthermore, if we are unable to repay the convertible senior secured notes due 2024 upon an acceleration or otherwise, we would be forced into bankruptcy or liquidation and we would lose title to substantially all of our assets, including our intellectual property.

The commercial success of Inbrija (levodopa inhalation powder) and any other future products are highly dependent on market acceptance among physicians, patients and the medical community, adequate reimbursement by governmental and other third party payers, and other factors.

We face significant challenges in successfully commercializing our approved pharmaceutical products, including Inbrija. Generally, market acceptance of our products depends on the benefits of our products in terms of safety, efficacy,

36

convenience, ease of administration and cost effectiveness and our ability to demonstrate these benefits to physicians, patients and third party payers. Commercial success requires significant investment in sales, marketing and market access efforts, and is dependent on how well we develop and implement strategies for these efforts. Commercial success is also subject to numerous other risks, including those described below, some of which are described in further detail elsewhere in these risk factors:

Also, in the U.S., the federal government provides funding for comparative effectiveness research, which may compare our products with other treatments and may result in published findings that would, in turn, discourage use of our products by physicians and payments for our products by payers. Similar research is funded in other countries, including in some countries in Europe.

The failure of any of our products or product candidates, once approved, to achieve market acceptance would limit our ability to generate revenue and would harm our results of operations and could adversely affect our future prospects. If market acceptance of our products in the U.S., EU, or other countries does not meet expectations, our revenues or royalties from product sales would suffer and this could cause our stock price to decline or could otherwise adversely affect our stock price.

37

We face risks related to health epidemics, such as the current COVID-19 (novel coronavirus) pandemic, that could adversely affect our operations or financial results.

Our business and financial condition have been impacted by, and are subject to the ongoing risks resulting from, the COVID-19 pandemic. The COVID-19 pandemic has caused significant disruptions in the healthcare industry. The duration of the pandemic and its potential economic impact are difficult to predict, and is likely to have continuing impacts. The travel restrictions, “shelter in place” orders, quarantine policies, and general concerns about the spread of COVID-19 have disrupted the delivery of healthcare to patients, for example making it more difficult for some patients to visit with their physician and obtain pharmaceutical prescriptions. Also, healthcare office staffing shortages may delay the administrative work, and particularly insurance-related documentation, needed to obtain reimbursement for prescriptions. We believe these factors contributed to decreases in new Inbrija prescriptions during several periods in 2020. In addition, the COVID-related policies, restrictions and concerns may disrupt our operations and those of our customers and suppliers. Furthermore, our operations could be interrupted if we or our customers or suppliers lose the services of key employees or consultants who become ill from COVID-19. These types of disruptions could potentially affect any of our critical business functions, and thus harm our business, including for example our manufacturing, sales and marketing operations as well compliance and certain general and administrative functions. The ultimate impact of the COVID-19 pandemic, or any other health epidemic, is highly uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, healthcare systems or the global economy as a whole. As the pandemic continues, it may result in a sustained economic downturn that could affect demand for our products and our ability to access capital on reasonable terms, or at all. These factors could have a material adverse effect on our business, operating results and financial condition.

We operate in the highly-regulated pharmaceutical industry.

Pharmaceutical research, development, preclinical and clinical trial activities, as well as the manufacture and marketing of any products that we have developed or in the future may successfully develop, are subject to an extensive regulatory approval process by the FDA and other regulatory agencies and authorities abroad.

Both in the U.S. and foreign jurisdictions, the process of obtaining required regulatory approvals for drugs is lengthy, expensive and uncertain. Any regulatory approvals may be for fewer or narrower indications than we request, may include distribution restrictions, or may be conditioned on burdensome post-approval study or other requirements, including the requirement that we institute and follow a special risk evaluation and mitigation strategy, or REMS, to monitor and manage potential safety issues, all of which may eliminate or reduce the drug's market potential. Additional adverse events that could impact commercial success, or even continued regulatory approval, might emerge with more extensive post-approval patient use. In the U.S., investigational products that rely on device components to deliver drug to patients, such as Inbrija, are regulated as combination products and require that we satisfy FDA that both the drug and device component of the products satisfy FDA requirements. Failure to satisfy the FDA’s requirements for either the drug or device component of such combination products could delay approval of these products or result in these products not receiving FDA approval. In the EU, where Inbrija has received a marketing authorization, both the drug and device components are regulated under the EU’s medicines rules, which, among other things, require the device component to comply with the essential legal requirements for medical devices. Failure to meet these requirements could adversely affect our ability to market Inbrija in the European Economic Area, or EEA.

Any product for which we currently have or may in the future obtain marketing approval is subject to continual post-approval requirements including, among other things, record-keeping and reporting requirements, packaging and labeling requirements, requirements for reporting adverse drug experiences, import/export controls, restrictions on advertising and promotion, current Good Manufacturing Practices (cGMP) requirements as well as, for example in the U.S., any other requirements imposed by the applicant’s NDA or BLA. All of our products and operations are subject to periodic inspections by the FDA and other regulatory authorities. Regulatory approval of a product may be subject to limitations on the indicated uses for which the product may be marketed or to other restrictive conditions of approval that limit our ability to promote, sell or distribute a product. Furthermore, any approval may contain requirements for costly post-marketing testing and surveillance to monitor the safety or efficacy of the product. Post-market evaluation of a product could result in marketing restrictions or withdrawal from the market. In addition, in the EU, if we do not place a product (e.g., Inbrija) on the market within three years of its first marketing authorization, the EU marketing authorization would lapse under the EU’s sunset rules.

We may fail to comply with existing legal or regulatory requirements or be slow to adapt, or be unable to adapt, to new legal or regulatory requirements. We may encounter problems with manufacturing processes for our products, and we may discover previously unknown problems with our products. These circumstances could result in:

38

In addition, we are subject to regulation under other state, federal and foreign laws and regulations, including requirements regarding occupational safety, laboratory practices, environmental protection and hazardous substance control, controlled substances and we may be subject to other local, state, federal and foreign regulations. We cannot predict the impact of those regulations on us, although they could impose significant restrictions on our business and we may have to incur additional expenses to comply with them. We may rely on collaborators within or outside the U.S. for the manufacture, sale and/or marketing of our pharmaceutical products. The failure of these other companies to comply with laws and regulations applicable to them or the activities they perform for us could similarly harm our business.

We have no manufacturing capabilities for our products or product candidates, and we are dependent upon third-parties to supply the materials for, and to manufacture, our products and product candidates.

We do not own or operate, and currently do not plan to own or operate, facilities for production and packaging of our products or product candidates. We rely and expect to continue to rely on third parties for the production and packaging, active pharmaceutical ingredients, or APIs, inactive ingredients, and finished dosage forms of our products and product candidates, and where relevant any medical devices that are part of our products or product candidates. We similarly expect to continue to rely on third parties for the supply of materials for research and development activities, particularly any clinical trials we may conduct in the future. In addition, due to the unique manner in which our products are manufactured, in many cases we rely on single source providers for our commercial and investigational products, or components of those products. This dependence on others may harm our ability to develop and commercialize our products on a timely and competitive basis. Any such failure may result in decreased product sales and lower product revenue, which would harm our business.

As further described below in these risk factors, we sold our Chelsea, Massachusetts manufacturing operations to Catalent Pharma Solutions and now rely on Catalent for the manufacture and supply of Inbrija. As our Inbrija supplier, Catalent is responsible for all Inbrija components other than the inhaler and levodopa, the Inbrija API. We have relied, and we expect to continue relying, on single third-parties to supply the inhaler and levodopa. Also, we rely on a single third party to package Inbrija kits after they are manufactured. Any failure or delay by a third party manufacturer, packager, or supplier may delay or impair our ability to commercialize Inbrija or to complete any future clinical studies that may be needed. Although in some cases we have contracts for these requirements, we cannot be certain that those contracts will be renewed on commercially reasonable terms, if at all. This may be made more complex in certain circumstances if we do not have contracts with suppliers, such as in the case of Inbrija where we currently do not have a contract with the supplier of the API, which exposes us to the risk that they could discontinue supply at any time. Manufacturers, packagers or suppliers may choose not to conduct business with us at all, or may choose to discontinue doing business with us, for example if they determine that our particular business requirements would be unprofitable or otherwise not appropriate for their business. We do not control how Catalent sources the other components of Inbrija, and our business could be similarly exposed to risk if and to the extent they rely on single source suppliers or do not have supply contracts.

39

We currently rely on a single third party molding manufacturer for supply of the Inbrija inhalers. Our reliance on a third party for the manufacture of inhalers increases the risk that we will not have sufficient quantities of our inhalers or will not be able to obtain such quantities at an acceptable cost or quality, which could delay, prevent or impair our commercialization of Inbrija. If the inhaler supplier fails to provide sufficient inhaler supply, we would need enter into alternative arrangements with a different suppler. Transition to a new inhaler supplier would be a lengthy and complex process. Among other things, we would have to revalidate the molding and assembly processes pursuant to FDA requirements and we would have to ensure that inhalers manufactured by the new supplier adhere to other applicable regulatory requirements.

Our reliance on third party manufacturers, packagers, and suppliers subjects us to risks associated with their businesses and operations. For example, even if we have agreements with third parties, they may not perform their obligations to us and/or they may be unable or unwilling to establish or increase production capacity commensurate with our needs. Also, third party manufacturers, packagers, and suppliers are subject to their own operational and financial risks that are outside of our control, and potentially their control also, that may cause them to suffer liquidity or operational problems and that could interfere with their business operations. For example, their operations and/or ability to source raw materials and other supplies may be interrupted by natural disasters, acts of war, terrorism, or disease outbreaks (such as the recent outbreak of COVID-19, or the novel coronavirus). In addition, the manufacture and distribution of our products and product candidates, including product components such as API, and the manufacture of medical devices, are highly regulated, and any failure to comply with regulatory requirements could adversely affect our supply of products or our access to materials needed for product development. The third parties we rely on are subject to regulatory review, and any regulatory compliance problems could significantly delay or disrupt commercialization of our products. U.S. and foreign governments and regulatory authorities continue to propose legislative and other measures relating to the manufacture or distribution of pharmaceutical products, including revisions to current good manufacturing practices, or cGMPs. Third party manufacturers may be unable or unwilling to comply with new legislative or regulatory measures, and/or compliance with new requirements could increase the price we must pay for our products.

The manufacturing facilities used to produce our products, including those of our third party manufacturers, packagers and suppliers, must comply with cGMPs and will likely have to pass a pre-approval FDA inspection and potentially other inspections required by other regulatory authorities. Third party manufacturers, packagers and suppliers are also subject to periodic inspections for cGMP compliance from the FDA and potentially other regulatory authorities. Failure to pass such inspections and otherwise satisfactorily complete the requisite approval regimen with respect to our products or product candidates may result in regulatory actions by the FDA and other regulatory authorities, such as the issuance of FDA Form 483 notices of observations, warning letters, injunctions, facility shut-downs, product seizures, loss of operating licenses, and other civil and criminal penalties. Based on the severity of the regulatory action, our clinical or commercial supplies could be interrupted or limited, which could have a material adverse effect on our business. In some cases, these third party manufacturers may also be subject to GMP inspections by foreign regulatory authorities. Failure to pass such inspections by foreign regulatory authorities could impede our ability to manufacture product needed for clinical trials or impede our ability to secure product approvals.

If any of our third party manufacturers, packagers or suppliers fails to perform their obligations to us or otherwise have an interruption in or discontinue supply to us, we may be forced to seek a different third party manufacturer, packager or supplier. In such event, we may experience significant delays associated with finding an alternative manufacturer, packager or supplier that is both available on commercially acceptable terms and conditions, and also properly qualified in accordance with our specifications and the requisite regulatory requirements, such as those of the FDA and other regulatory authorities. This transition may require time consuming and complex operational, testing, and regulatory approval requirements, and the process could interfere with product sales because of inadequate supply or cause interruptions of, or delays in, research and development programs. We may not be able to establish arrangements with an alternative manufacturer, packager or supplier on reasonable terms, if at all. In some cases, the technical skills required to manufacture our products or product candidates or the API, excipients or other components of such products or product candidates may be unique or proprietary to the original manufacturer or supplier and we may have difficulty, or there may be contractual restrictions prohibiting us from, transferring such skills to a backup or alternative supplier, or we may be unable to transfer such skills at all.

We rely on Alkermes to supply us with our requirements for Ampyra. We and Alkermes also rely on a single third party manufacturer to supply dalfampridine, the active pharmaceutical ingredient, or API, in Ampyra, and also a single supplier for a critical excipient used in the manufacture of Ampyra. We also rely on a single third party to package Ampyra. If these companies experience any disruption in their operations, our supply of Ampyra could be delayed or interrupted until the problem is solved or we locate another source of supply or packager, which may not be available. We may not be able to enter into alternative supply or packaging arrangements on terms that are commercially reasonable, if at all. Any new

40

supplier or packager would also be required to qualify under applicable regulatory requirements. Because of these and other factors, we could experience substantial delays before we are able to obtain qualified replacement products or services from any new supplier or packager.

Also, under our supply agreement with Alkermes, we provide Alkermes with monthly written 18-month forecasts and with annual written five-year forecasts for our supply requirements of Ampyra. In each of the three months for Ampyra following the submission of our written 18-month forecast, we are obligated to purchase the quantity specified in the forecast, even if our actual requirements are greater or less. Given the introduction of generic competition to Ampyra in the market, it may be difficult to forecast the level of supply needed to satisfy our requirements in the future.

We completed the sale of our Chelsea, Massachusetts manufacturing operations in February 2021, and accordingly we rely on Catalent as our sole supplier for the manufacture of Inbrija (levodopa inhalation powder) and the manufacture of any ARCUS product candidates we may seek to further develop.

In connection with the sale of the Chelsea manufacturing operations, we entered into a long-term global supply agreement under which a Catalent affiliate will manufacture Inbrija on an exclusive basis (other than for sale in China). We are reliant on Catalent for all of our Inbrija supply and, subject to the negotiation of an amendment or new supply agreement, supply of other ARCUS inhaled therapeutic product candidates. Although Catalent has significant experience in commercial manufacturing, given applicable regulatory requirements and the complexity of the manufacturing processes for pharmaceuticals, Catalent may be unable or otherwise not successful in passing any required regulatory inspection prior to manufacturing, carrying out its contractual duties, meet expected deadlines or effectively manufacture or release Inbrija in a timely manner in accordance with current good manufacturing practices and other regulatory requirements. If we are unable to obtain adequate supplies of Inbrija under our supply agreement with Catalent, or if the supplies we receive do not meet quality and safety standards, we could face supply shortages, significant additional costs, product liability claims and reputational harm. Any of these factors, alone or in combination, could materially harm our business, financial condition, results of operations and prospects.

Currently, we are not investing in any research and development programs pending further progress with the Inbrija launch. However, should we decide in the future to make investments in any ARCUS development program, we would be reliant on Catalent for the manufacture of product for that program. Also, due to reductions in force, employee attrition and the 2021 sale of our Chelsea manufacturing operations, we believe we lack certain personnel needed for, and would need to hire replacements before continuing with, this research and development work. Our global supply agreement does not provide for the terms and conditions under which Catalent would supply any product or product candidate other than Inbrija, or under which Catalent would provide support for future ARCUS research and development. We would be unable to advance the development of any ARCUS inhaled therapeutic candidate unless Catalent is willing to manufacture the candidate for us and provide any necessary research and development support on commercially reasonable terms.

Establishing our global supply agreement with Catalent required that we share proprietary trade secrets and know-how relating to Inbrija and our ARCUS platform. We have sought to protect that information pursuant to various operational safeguards and confidentiality and other requirements set forth in the global supply agreement. We are reliant on Catalent’s compliance with those provisions, and even if Catalent does comply with those provisions, they may not provide adequate protection or prevent the unauthorized use or disclosure of the information. The unauthorized use or disclosure of our proprietary information could harm its value by enabling others to copy or use our information for their own products, methods or technologies, and we may not have an adequate remedy against Catalent or any other party for the harm caused.

Our global supply agreement with Catalent contains substantial long-term financial commitments.

Under our agreement with Catalent, we are obligated to make minimum purchases from Catalent through the expiration of the agreement on December 31, 2030. The minimum amounts are $16 million in 2021 (prorated), and then $18 million each year thereafter. Currently, these minimum purchase commitments exceed our supply needs for Inbrija, and we cannot be certain whether and when our supply needs will meet or exceed these amounts. Even if we are forced to obtain Inbrija from another supplier because Catalent is unable or unwilling to provide adequate Inbrija supply, we may be unable to offset the costs of alternate supply against our minimum purchase commitments under the Catalent supply agreement. Lastly, if we choose to terminate the Catalent agreement for convenience, we would be obligated to pay a substantial termination fee.

We rely on Catalent’s Chelsea, Massachusetts manufacturing facility for the manufacture of Inbrija (levodopa inhalation powder), and our business could be harmed if Catalent does not maintain required regulatory approvals to manufacture

41

commercial product at that facility, if there is an interruption in operations at the facility, or if the facility does not have manufacturing capacity needed to meet product demand.

All commercial supply of Inbrija is currently manufactured at Catalent’s Chelsea, Massachusetts manufacturing facility. Under our long-term global supply agreement with Catalent, Inbrija will be exclusively manufactured by Catalent at this manufacturing facility (other than for sale in China, which is not covered by the exclusivity provisions of the agreement). Catalent may need expanded manufacturing capacity at the Chelsea facility to meet demand depending on the timing and extent of sales growth. Catalent’s inability to complete any needed expansion of the facility in a timely manner or unexpected demand for commercial quantities of Inbrija could cause a supply shortage that would harm our commercialization of Inbrija in the U.S. and any foreign jurisdictions where we may potentially commercialize Inbrija, such as in the EU where Inbrija has been granted a marketing authorization. If we or a collaborator launches Inbrija in an EU member state or another foreign jurisdiction, such supply shortages could lead to a breach of the legal obligation to ensure continuity of supply.

Furthermore, if Catalent were to lose the use of the facility or equipment, the manufacturing facility and manufacturing equipment would be difficult to replace and could require substantial replacement lead time and substantial additional funds. The facility may be affected by natural disasters, such as floods or fire, or Catalent may lose the use of the facility due to manufacturing issues that arise, such as contamination or regulatory concerns following a regulatory inspection of the facility. Catalent may also unexpectedly experience manufacturing issues as the unintended result of activities occurring at the facility unrelated to Inbrija manufacture. In the event of a loss of the use of all or a portion of the facility or equipment for the reasons stated above or any other reason, Catalent would be unable to manufacture Inbrija until such time as the facility or equipment could be repaired or rebuilt or they are able to address other manufacturing issues at the facility. Any such interruptions in their ability to manufacture Inbrija would harm our business. Even if Catalent does not suffer a loss of the facility or equipment within the facility, manufacturing operations can experience intermittent interruptions due to the need for routine or unexpected maintenance, inspection and repairs of the facility or the equipment, and, depending on their frequency and duration, these intermittent interruptions could also harm our business.

We do not have back-up manufacturing capability for Inbrija or any ARCUS product candidates, and if Catalent fails to timely perform under our global supply agreement our business, financial condition, results of operations and prospects could be harmed.

If we are unable to obtain adequate supplies of Inbrija under our supply agreement with Catalent, or if the supplies we receive do not meet quality and safety standards, we could face supply shortages, significant additional costs, product liability claims and reputational harm. Also, if we decide to make further investments in any ARCUS product development programs, we would be unable to advance those programs unless we could obtain adequate supply of the inhaled therapeutic product candidate from Catalent and on commercially reasonable terms.

We do not currently have back-up manufacturing capability at another facility and there are only limited third party manufacturers that we believe would be capable of manufacturing Inbrija or other ARCUS inhaled therapeutic products or product candidates. If the need arises to obtain supply from another third party manufacturer, there can be no assurance that we could identify a third party that would be capable and willing to manufacture for us on commercially reasonable terms, if at all, or that they could supply us in sufficient quantities on a timely basis to meet our needs.

Engaging a third party manufacturer to supply ARCUS products or product candidates would likely be a lengthy process due to the complexity and substantial regulation of the manufacturing processes involved. Also, engaging a third party would require the sharing of proprietary information, which increases the risk of the unauthorized use or disclosure of that information and potential harm to our business for which we may not have an adequate remedy. If we are successful in engaging a third party manufacturer, they may not perform their obligations to us and/or they may be unable or unwilling to establish or increase production capacity commensurate with our needs. Also, third party manufacturers and suppliers are subject to their own operational and financial risks that are outside of our control, including macro-economic conditions that may cause them to suffer liquidity or operational problems and that could interfere with their business operations.

Catalent may not successfully complete the expansion of the Chelsea, Massachusetts manufacturing facility.

Catalent may need expanded manufacturing capacity at the Chelsea facility to meet Inbrija demand depending on the timing and extent of sales growth. In 2018, prior to our sale of the Chelsea manufacturing operations to Catalent, we initiated a renovation and expansion of the Chelsea facility that increased the size of the facility to approximately 95,000 square feet. The project added a new manufacturing production line for Inbrija and other ARCUS products that has greater capacity than

42

the existing manufacturing line, and has created additional warehousing space for manufactured product. Although the project was substantially completed in late 2019, the expansion does not yet have all of the approvals needed for use of the new production line for commercial manufacture, such as approvals from the FDA, Massachusetts state environmental permits, and approvals from other regulatory authorities. Also, manufacturing scale-up generally is subject to significant risks related to process development and manufacturing yields, which is especially true for the manufacture of a product such as Inbrija which involves a highly specialized spray drying and capsule filling process. Lastly, the expanded Chelsea facility will have to continue to comply with cGMP requirements, as described above in these risk factors, as well as other applicable environmental, safety, and other governmental permitting requirements.

These challenges could delay or prevent Catalent from successfully completing the expansion of the Chelsea manufacturing capacity. If we need the expanded capacity but Catalent is delayed in or prevented from completing the expansion and obtaining necessary regulatory approvals, we may need to seek another party to manufacturer additional Inbrija supply for us. As described above in these risk factors, there can be no assurance that we could identify a third party that would be capable and willing to manufacture for us on commercially reasonable terms, if at all, or that they could supply us with product in sufficient quantities on a timely basis to meet our needs. If we cannot obtain increased supply of Inbrija from expanded capacity at the Chelsea facility or engaging another third party manufacturer, we may not be able to meet demand for Inbrija and this could harm our ability to commercialize Inbrija in the U.S. and any foreign jurisdictions where we may potentially commercialize Inbrija, such as in the EU where Inbrija has received a marketing authorization. If we or a collaborator launches Inbrija in an EU member state or another foreign jurisdiction, such an inability to meet demand could lead to a breach of the legal obligation to ensure continuity of supply.

We may incur significant liability if we fail to comply with stringent FDA marketing and promotion regulations and those in other applicable markets.

Our advertising and promotion activities are subject to stringent rules and requirements both in the U.S. and other jurisdictions, which are enforced and overseen by the FDA and other regulatory authorities in other jurisdictions. These rules and requirements vary from country to country and promotional practices and materials that are acceptable in one country may not be so in another. Importantly, unlike in the U.S., EU law prohibits the advertising of prescription-only medicinal products (such as Inbrija) directly to patients or the general public. Advertising to healthcare professionals is permitted, provided certain conditions are met.

Among other requirements, in the U.S. and EU, our advertising and promotional materials must not be false or misleading in any particular respect, and must be appropriately substantiated and fairly balanced with information on the safety risks and limitations of our products. In the U.S., we must submit all promotional materials to the FDA by the time of their first use. Some other jurisdictions also require government pre-approval of promotional materials. If the FDA or other regulators raise concerns regarding our promotional materials or messages, we may be required to modify or discontinue using them and may be required to provide corrective information. Should we fail to comply with the relevant requirements, in the U.S. or other countries, we may be subject to significant liability, including civil and administrative remedies as well as criminal sanctions.

Each of our products is approved with specific indications and other conditions of use that inform our ability to promote our products. For example, in the U.S., Inbrija (levodopa inhalation powder) is indicated “for the intermittent treatment of OFF episodes in people with Parkinson’s disease treated with carbidopa/levodopa.” The approved Summary of Product Characteristics, or SmPC, in the EU marketing authorization contains a similar indication. The approved labeling in the U.S. and the EU SmPC also contain other limitations on use and warnings and precautions, the most common adverse reactions, and contraindications for risks. If potential purchasers or those influencing purchasing or prescribing decisions, such as physicians and pharmacists, third-party payers or reimbursement authorities, react negatively to Inbrija or other products because of their perception of the limitations or safety risks in the approved product labeling, it may result in lower product acceptance and lower product revenues.

In the U.S., EU and many other jurisdictions, we face significant risks if we promote our drugs “off-label,” i.e., for uses other than those approved by the appropriate regulatory authority in a territory (e.g., the FDA in the U.S.). Physicians may prescribe drug products for uses that are not described in the product’s labeling and that differ from those approved by the FDA. Similar rules apply in many countries outside the U.S. Off-label uses are common across medical specialties. In the U.S., although the FDA does not regulate a physician’s choice of treatments, it traditionally has prohibited companies from promoting their drugs for off-label uses. Several federal court cases, based on First Amendment principles, have called into question the FDA’s ability to enforce against companies solely on the basis of truthful and non-misleading off-label promotion of their drugs. It is unclear, however, how the courts ultimately will resolve this issue or how the FDA’s policies

43

may (or may not) change in light of developing case law. Furthermore, off-label promotion of our products could violate advertising and promotion requirements such as the prohibition against false or misleading advertising and/or labeling, or the requirement that approved labeling bear “adequate directions” for all of the product’s “intended uses.” Similarly, although EU law does not in general restrict the off-label use of a product by healthcare professional, it is unlawful to promote the off-label use of a product or promotion that is inconsistent with the product’s SmPC. Accordingly, we potentially face significant risk of enforcement should we promote Inbrija (levodopa inhalation powder), Ampyra or any other products in the U.S., EU and potentially other countries for any uses that are not consistent with the products’ approved labeling in the relevant territory. The FDA and other regulatory and enforcement authorities actively enforce laws and regulations regulating promotion of approved drugs as well as the promotion of products for which marketing approval has not been obtained. A company that is found to have violated these requirements may be subject to significant liability, including civil and administrative remedies as well as criminal sanctions both in the U.S. and potentially other jurisdictions.

Notwithstanding the above-described regulatory restrictions, the FDA and other applicable regulatory authorities and EU medicines laws allow companies to engage in truthful, non-misleading, and non-promotional scientific exchange concerning their products. We engage in medical education activities and communicate with investigators and potential investigators regarding our clinical trials. Although we believe that all of our communications regarding our marketed and investigational products are in compliance with applicable advertising and promotional regulations, the FDA or another regulatory or enforcement authority may disagree.

Any free samples we distribute to physicians must be carefully monitored and controlled, and, in the U.S., must otherwise comply with the requirements of the Prescription Drug Marketing Act, as amended, and FDA regulations.

The identification of new side effects from Inbrija (levodopa inhalation powder) or any other marketed drug products, or side effects from those products that are more frequent or severe than in the past, could harm our business by leading to a significant decrease in sales or to the withdrawal of marketing approval in the U.S. and/or in other jurisdictions.

Based on our clinical trials, the most common adverse reactions with Inbrija (at least 5% and greater than placebo) include cough, upper respiratory tract infection, nausea and discolored sputum. We constantly monitor Inbrija adverse event reports for signals regarding potential additional adverse events.

If we or others identify previously unknown side effects, if known side effects are more frequent or severe than in the past, or if we or others detect unexpected safety signals for Inbrija or any products perceived to be similar to Inbrija, then in any of these circumstances:

The above occurrences could impair our business by harming or possibly preventing sales of Inbrija, causing sales to fall below projections, and increasing our expenses. The same risks apply to our other marketed products, such as Ampyra.

44

Regulatory approval of our products could be withdrawn and our business could be harmed if we fail to comply with safety and adverse event monitoring, documentation, investigation and reporting requirements.

Under FDA and EU rules and regulations, we are required to monitor the safety of Inbrija and Ampyra, as applicable, and in the case of Ampyra inform healthcare professionals about the risks of drug-associated seizures with Ampyra. We are required to document and investigate reports of adverse events, and to report them to the FDA and EU authorities in accordance with regulatory timelines based on their severity and expectedness. These requirements are applicable to all medicinal products marketed in the relevant territory, including Inbrija (levodopa inhalation powder) and Ampyra. Failure to make timely safety reports and to establish and maintain related records could result in the withdrawal of marketing authorization or other regulatory action, civil actions against us, or criminal or financial penalties, any of which could harm our business. If specialty pharmacies, marketing partners, or collaborators fail timely to report adverse events and product complaints to us, or if we do not meet the requirements for safety reporting, our business may be harmed.

We are subject to periodic unannounced inspections by the FDA and other regulatory authorities related to other regulatory requirements that apply to drugs manufactured or distributed by us.

If we receive a notice of inspectional observations or deficiencies from the FDA or from foreign regulatory authorities, we may be required to undertake corrective and preventive actions in order to address the relevant regulatory authority’s concerns, which could be expensive and time-consuming to complete and could impose additional burdens and expenses. Failure to adequately address any such concerns could expose us to enforcement and a range of potential sanctions.

In addition, our third party suppliers’ drug product manufacturing sites are subject to inspection by the FDA and possibly also foreign regulatory authorities. Some of these sites have been inspected by the FDA and could be inspected by the FDA in the future. If the FDA inspects the process validation efforts and manufacturing process at these sites, the FDA might find what it considers to be deficiencies in the manufacturing process or process validation efforts, which could negatively impact the availability of product supply or, in the case of a potential new product, delay or prevent commercial launch of that product. In some cases, our third party suppliers’ drug manufacturing sites may also be subject to inspection by foreign regulatory authorities. We face similar risks to our business if those third party manufacturers are unable to comply with foreign regulatory requirements. We and our third party suppliers are generally required to maintain compliance with cGMPs and are subject to inspections by the FDA or comparable authorities in other jurisdictions to confirm such compliance. This may be made more complex in certain circumstances if we do not have contracts with suppliers, such as in the case of Inbrija where we currently do not have a contract with the supplier of levodopa, the active pharmaceutical ingredient. In addition, the FDA and other relevant regulatory authorities must approve certain changes to our suppliers or manufacturing methods. If we or our third party suppliers cannot demonstrate ongoing cGMP compliance, we may be required to withdraw or recall product and interrupt commercial supply of our products. Any delay, interruption or other issues that arise in the manufacture, fill-finish, packaging, or storage of our products as a result of a failure of our facilities or the facilities or operations of our third party suppliers, to pass regulatory agency inspection could significantly impair our ability to develop and commercialize our products. Significant noncompliance could also result in the imposition of monetary penalties, shut-down of manufacturing facilities, or other civil or criminal sanctions. Non-compliance could increase our costs, cause us to lose revenue, and damage our reputation.

Even if our suppliers or manufacturing methods are in compliance with applicable requirements, we may encounter problems with the manufacture of our products. To investigate and/or resolve these problems, we may be required to withdraw or recall product and interrupt commercial supply of our products. These events could increase our costs, cause us to lose revenue, and damage our reputation. If we learn of certain reported problems with our products, we are required to submit field alert reports to the FDA and quality defect reports to the relevant EU authorities, such as the EMA, and we are required to investigate the causes of the reported problems. Issues identified in field alerts could lead to product recalls and interruption of supplies, which in turn could harm our business.

Also, the Federal Food, Drug & Cosmetic Act requires that our manufacturers, repackagers, wholesale distributors, and dispensers, take certain actions when product in their possession or control is suspect product, meaning there is reason to believe the product is: counterfeit; diverted; stolen; intentionally adulterated such that the product would result in serious adverse health consequences or death to humans; is the subject of a fraudulent transaction; or appears otherwise unfit for distribution such that the product would be reasonably likely to result in serious adverse health consequences to humans. The suspect product is required to be quarantined while an investigation is promptly conducted to determine whether the product is illegitimate, meaning credible evidence shows that it meets any of the above criteria. If a product is deemed an illegitimate product, additional requirements apply such as notifying the FDA and all immediate trading partners in the supply chain within 24 hours and quarantining the product until it is dispositioned. Similar requirements exist under EU law, particularly

45

pursuant to the Falsified Medicines Directive (Directive 2011/62/EU). The notification, quarantine and/or dispositioning of product during an investigation could impact product availability for commercial distribution and harm our business.

We rely on specialty pharmacies to dispense our products, deliver customer support, and provide us with related services, and our business could be harmed and we could be subject to liabilities if these services are performed inadequately or in a manner that does not comply with applicable laws and regulations.

A specialty pharmacy is a pharmacy that specializes in the dispensing of injectable, infused or certain other medications typically for complex or chronic conditions, including Parkinson’s disease and multiple sclerosis, which often require a high level of patient education and ongoing management. Most of our Inbrija and Ampyra sales are sold through specialty pharmacies, and sales of these products are highly dependent on the performance of these specialty pharmacies.

The use of specialty pharmacies involves risks, including, but not limited to, risks that these specialty pharmacies:

If our specialty pharmacies do not fulfill their contractual obligations to us or fail to adequately dispense our products and deliver customer support, our product sales and business could be harmed or we could be subject to legal or regulatory liabilities or sanctions. Also, for U.S. sales of Inbrija, we have transitioned from a network of several specialty pharmacies to Alliance Rx Walgreens Prime, or Walgreens, as the sole specialty pharmacy. While we believe this change has potential benefits to patients and our business, reliance on a single specialty pharmacy also potentially increases the risks described above because we do not have a backup specialty pharmacy to dispense Inbrija and provide related services if an issue arises with Walgreens. We expect that it would take a significant amount of time if we were required to change from Walgreens to another specialty pharmacy.

Furthermore, arrangements between manufacturers and specialty pharmacies can be subject to government scrutiny and challenge under fraud and abuse laws if not structured properly.

We are dependent on our existing collaborations, and may need additional collaborations, to develop and commercialize products outside of the U.S.

We have not yet developed the capabilities to commercialize products outside of the U.S. Pursuant to our Collaboration Agreement with Biogen, entered into in June 2009, we granted Biogen an exclusive license to develop and commercialize Ampyra and other products containing aminopyridines in territories outside the U.S. We may enter into additional collaborations with third parties to develop and commercialize some of our product candidates in the future. For example, we will need to enter into collaborations to commercialize Inbrija (levodopa inhalation powder) in the EU, as well as other countries outside of the U.S. if it receives marketing approval in any other countries, and similarly we would need to rely on collaborations for developing and commercializing any other potential products outside of the U.S. We cannot provide any assurance that we will be able to identify suitable collaboration partners for Inbrija or other potential products, or that we will be able to enter into collaboration agreements with proposed partners on commercially reasonable terms, if at all. Our inability to identify collaboration partners or enter into collaborations could harm or delay our efforts to develop and commercialize Inbrija or other potential products outside of the U.S.

46

Our dependence on collaborators for development and commercialization of products and product candidates outside the U.S., is and will subject us to a number of risks, including:

While we seek contractual terms and conditions intended to protect our rights and mitigate our risk relating to circumstances listed above, there can be no assurance that these terms will provide us with adequate rights and remedies, and actions required to enforce such rights could be costly and time consuming.

We do not currently receive any royalties from Biogen for sales of Fampyra, and we cannot predict whether and when we will receive additional Fampyra royalties.

Under the terms of our 2017 Fampyra royalty monetization transaction with HealthCare Royalty Partners, we will not receive royalties from the sale of Fampyra until they receive an agreed-upon threshold of royalties. After this threshold is met, if ever, we will continue to receive Fampyra royalty revenue under the terms of our collaboration agreement with Biogen. We cannot predict whether and when that threshold will be met, as this will depend on Biogen’s ability to commercialize Fampyra, although we expect it will take several more years. Biogen’s commercialization of Fampyra will depend on factors such as Biogen’s ability to obtain and maintain regulatory approvals and to obtain adequate third party reimbursement as described further in these risk factors. Also, we do not know if Biogen will obtain approval to market Fampyra in any new jurisdictions in the near future, if ever, which limits the potential for growth in Fampyra sales and accordingly whether and when we may receive additional Fampyra royalties.

Our collaborators will need to obtain and maintain regulatory approval in foreign jurisdictions where they seek to market or are currently marketing our products.

In order to market our products in the EU and other foreign jurisdictions, separate regulatory approvals must be obtained and maintained and numerous and varying regulatory requirements must be complied with. Approval procedures

47

vary among countries and can involve additional clinical and non-clinical testing as well as additional regulatory agency inspections. The time required to obtain approval may differ from that required to obtain FDA approval. We and our collaborator may fail to obtain foreign regulatory approvals on a timely basis, if at all. In addition, individual countries, within the EU or elsewhere, may require additional steps after regulatory approval to gain access to national markets, such as agreements with pricing authorities and other agencies, that may harm the ability of us or our collaborator to market and sell products outside the U.S. Approval by the FDA does not ensure approval by regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other foreign countries or by the FDA. Inability to obtain or maintain necessary regulatory approvals to commercialize Inbrija, Fampyra or other products or product candidates in foreign markets could materially harm our business prospects. In addition, we may face adverse legal and business consequences if Biogen, our collaboration partner for Fampyra, does not comply with regulatory requirements, and if we enter into any collaborations for the marketing of Inbrija, we similarly could face adverse legal and business consequences if we or any Inbrija collaborator does not comply with regulatory requirements.

Drug development programs, particularly those in early stages of development, may never be commercialized.

Future growth of our business will depend, in part, on our ability to select successful product candidates, complete preclinical development of these product candidates and advance them to and through clinical trials. We have research and development programs that are early-stage and either have not advanced to clinical trials or are only in Phase 1 trials. These early-stage product candidates in particular will require significant development, preclinical studies and clinical trials, regulatory clearances and substantial additional investment before they can be commercialized, if at all. Currently, we are not making any new investments in these programs, and we have deferred consideration of further investment pending additional progress with the Inbrija launch.

Even if we do make future investments in our research and development programs, they may not lead to commercially viable products for several reasons, and are subject to the risks and uncertainties associated with drug development described elsewhere in these risk factors. For example, we may fail to identify promising product candidates, our product candidates may fail to be safe and effective in preclinical tests or clinical trials, or we may have inadequate financial or other resources to pursue discovery and development efforts for new product candidates. We have currently suspended work on all research and development programs, other than work funded by third party grants, because of our limited financial resources. Also, as a result of reductions in force in recent years, we have terminated substantially all of our research and development and clinical development workforce, and accordingly we lack personnel necessary to advance our development programs unless and until we can hire qualified replacements.

From time to time, we may establish and announce certain development goals for our product candidates and programs. However, given the complex nature of the drug discovery and development process, it is difficult to predict accurately if and when we will achieve these goals. If we are unsuccessful in advancing research and development programs into clinical testing or in obtaining regulatory approval, our long-term business prospects could be harmed.

Drug products in development must undergo rigorous clinical testing, the results of which are uncertain and could substantially delay or prevent us from bringing them to market.

Before we can obtain regulatory approval for any product candidate, we must undertake extensive clinical testing in humans to demonstrate safety and efficacy to the satisfaction of the FDA, EU regulatory authorities and other regulatory agencies. Clinical trials of new product candidates sufficient to obtain regulatory marketing approval are expensive and take years to complete, and the outcome of such trials is uncertain. Clinical development of any product candidate that we determine to take into clinical trials may be curtailed, redirected, delayed or eliminated at any time for some or all of the following reasons:

48

A delay in or termination of any of a clinical development program that we are conducting could harm our business.

Clinical trials are subject to oversight by institutional review boards (or similar ethics committees), data safety monitoring boards, the FDA and similar regulatory authorities in other countries to ensure compliance with good clinical practice requirements, as well as other requirements for the protection of clinical trial participants. We depend, in part, on third party laboratories and medical institutions to conduct preclinical studies and clinical trials for our products and other third party organizations to perform data collection and analysis, all of which must maintain both good laboratory and good clinical practices required by regulators. If any of those standards are not complied with in a clinical trial, the resulting data from the clinical trial may not be usable or we, an institutional review board, the FDA or a similar regulatory authority in another country may suspend or terminate a trial, which would severely delay our development and possibly end the development of the product candidate.

If we proceed with research and development programs, we will rely on third party contract research organizations, medical centers and others to perform preclinical and non-clinical testing and clinical trials, and research and development programs could be harmed if these third parties do not perform in an acceptable and legally compliant manner.

If we proceed with research and development programs, we will rely on clinical investigators, third party contract research organizations and consultants to perform some or all of the functions associated with preclinical and non-clinical testing and clinical trials. Additionally, we have historically conducted clinical trials in the U.S., Canada, and to a lesser extent other jurisdictions, particularly Europe. Because we have limited experience conducting clinical trials outside the U.S. and Canada, we would place even greater reliance on third party contract research organizations to manage, monitor and carry out clinical trials in these other jurisdictions. The failure of any of these parties to perform in an acceptable and timely manner in the future, including in accordance with any applicable U.S. or foreign regulatory requirements, such as good clinical and laboratory practices, or preclinical testing or clinical trial protocols, could cause a delay or other adverse effect on preclinical or non-clinical testing or clinical trials and ultimately on the timely advancement of research and development programs. Similarly, we would rely on medical centers to conduct clinical trials, and if they fail to comply with applicable regulatory requirements or clinical trial protocols, our research and development programs could be harmed.

If we market products in a manner that violates healthcare fraud and abuse laws, or if we violate false claims laws or fail to comply with our reporting and payment obligations under the Medicaid drug rebate program or other governmental pricing programs, or other applicable legal requirements, we may be subject to civil or criminal penalties or additional reimbursement requirements and sanctions, which could harm our business, financial condition, results of operations and growth prospects.

The distribution, sale and promotion of drug and biological products in the U.S. and in foreign markets are subject to numerous laws and regulations. In the U.S., this includes regulation by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare and Medicaid Services, the Federal Trade Commission, other divisions of the U.S. Department of Health and Human Services, the Federal Trade Commission, the U.S. Department of Justice and individual U.S. Attorney offices within the Department of Justice, and state and local governments. For example, sales, marketing and scientific/educational grant programs must comply with the anti-kickback and fraud and abuse provisions of

49

the Social Security Act, as amended, the False Claims Act, as amended, and are affected by the privacy regulations promulgated pursuant to the Health Insurance Portability and Accountability Act, as amended, and similar state laws. Because of the breadth of these laws and the narrowness of safe harbors under these laws, it is possible that some of our business activities could be subject to challenge under one or more of these laws. All of these activities are also subject to federal and state consumer protection and unfair competition laws and regulations.

The federal healthcare program anti-kickback statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to induce, or in return for, purchasing, leasing, ordering or arranging for the purchase, lease or order of any healthcare item or service reimbursable under Medicare, Medicaid or other federally financed healthcare programs. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers, patients and formulary managers on the other. Industry relationships with specialty pharmacies have also recently been scrutinized under these provisions. There are several statutory exemptions and regulatory safe harbors protecting certain common activities from prosecution, but the exemptions and safe harbors are drawn narrowly, and our practices may not in all cases meet all of the criteria for exemptions or safe harbors. Practices that involve remuneration for performing activities that we believe are legitimate in support of the distribution of our products may be subject to scrutiny, particularly if they do not qualify for an exemption or safe harbor, and they may be found to be improperly intended to induce or facilitate the prescribing, purchasing or recommending of our products even though we believe these practices to be in compliance with applicable laws and regulations.

Federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government or knowingly making, or causing to be made, a false statement to get a false claim paid. By statute, a violation of the federal anti-kickback statute may serve as the basis for a false claim under the false claims act. Numerous pharmaceutical and other healthcare companies have been prosecuted under these laws for a variety of alleged promotional and marketing activities, such as: allegedly providing kickbacks, such as free trips, free goods, sham consulting fees and grants and other monetary benefits to prescribers; reporting to pricing services inflated average wholesale prices that were then used by federal programs to set reimbursement rates; and engaging in off-label promotion that caused claims to be submitted to Medicaid for non-covered, off-label uses. Most states also have statutes or regulations similar to the federal anti-kickback law and false claims laws, which apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payer.

Sanctions under these federal and state laws may include requirements to make payments to government-funded health plans to correct for insufficient rebates paid by us or overpayments made to us, civil monetary penalties, exclusion of our products from reimbursement under government programs, criminal fines and imprisonment. We may also be subject to a corporate integrity agreement, deferred prosecution agreement, or similar arrangement.

Under the federal Sunshine Act, pharmaceutical manufacturers are required to collect information on payments or other transfers of value made to “covered recipients,” which are defined as physicians and teaching hospitals. The collected information has to be disclosed in annual reports that are placed on a public database. Beginning with reports submitted in 2022 (for calendar year 2021) the Sunshine Act will also apply to payments to physician assistants and advance practice nurses. Similarly, the Affordable Care Act requires pharmaceutical manufacturers to annually report samples of prescription drugs requested by and distributed to healthcare providers. The law does not state whether these disclosures regarding samples will be made publicly available, and the FDA has not provided any guidance. If we fail to submit these reports, or if the reports we submit are not accurate, we could be subject to significant penalties.

We participate in the federal Medicaid drug rebate program established by the Omnibus Budget Reconciliation Act of 1990, as well as several state supplemental rebate programs. Under the Medicaid drug rebate program, we pay a rebate to each state Medicaid program for utilization of our products that is reimbursed by those programs. Federal law requires that any company that participates in the Medicaid drug rebate program extend comparable discounts to qualified purchasers under the Public Health Service Act pharmaceutical pricing program, which requires us to sell our products to certain customers at prices lower than we otherwise might be able to charge. The minimum basic Medicaid rebate for branded prescription drugs is 23.1% of average manufacturer price, and pharmaceutical manufacturers must pay states rebates on prescription drugs dispensed to Medicaid managed care enrollees. In addition, manufacturers must pay an additional Medicaid rebate on “line extensions” (such as extended release formulations) of solid oral dosage forms of branded products or products where the average manufacturer price has increased faster than the inflation rate.

For products to be made available to authorized users of the Federal Supply Schedule, additional pricing laws and requirements apply, as do certain obligations imposed by the Federal Acquisition Regulations. Under the Veterans Health Care Act of 1992, as amended (VHCA), we are required to offer certain drugs at a reduced price to a number of federal

50

agencies, including the Veterans Administration, the Department of Defense (DOD), the Public Health Service and certain private Public Health Service designated entities, in order to participate in other federal funding programs including Medicare and Medicaid. Participation under the VHCA requires submission of pricing data and calculation of discounts and rebates pursuant to complex statutory formulas, as well as the entry into government procurement contracts governed by the Federal Acquisition Regulations.

Pharmaceutical companies have been prosecuted under federal and state false claims laws for manipulating information submitted to the Medicaid drug rebate program or for knowingly submitting or using allegedly inaccurate pricing information in connection with federal pricing and discount programs.

Pricing and rebate calculations vary among products and programs. The laws and regulations governing the calculations are complex and are often subject to interpretation by us or our contractors, governmental or regulatory agencies and the courts. Our methodologies for calculating these prices could be challenged under false claims laws or other laws. We or our contractors could make a mistake in calculating reported prices and required discounts, revisions to those prices and discounts, or determining whether a revision is necessary, which could result in retroactive rebates (and interest and penalties, if any). Governmental agencies may also make changes in program interpretations, requirements or conditions of participation, some of which may have implications for amounts previously estimated or paid. If we make these mistakes or if governmental agencies make these changes, we could face, in addition to prosecution under federal and state false claims laws, substantial liability and civil monetary penalties, exclusion of our products from reimbursement under government programs, criminal fines or imprisonment or prosecutors may impose a Corporate Integrity Agreement, Deferred Prosecution Agreement, or similar arrangement.

Under the Affordable Care Act, or ACA, as amended, drug manufacturers are required to provide a 70% discount on prescriptions for branded products filled while the beneficiary is in the Medicare Part D coverage gap, also known as the “donut hole.” In addition, the ACA imposes a significant annual fee on companies that manufacture or import branded prescription drug products. The fee (which is not deductible for federal income tax purposes) is based on the manufacturer’s market share of sales of branded drugs and biologics (excluding orphan drugs) to, or pursuant to coverage under, specified U.S. government programs.

Outside the U.S., the distribution, sale and promotion of our products is subject to a variety of rules and requirements. In the EU, these vary from country to country and we and any collaborator must comply with all applicable rules in each relevant market. In many jurisdictions, these include both general anti-bribery rules, anti-inducement rules under medicines advertising laws and self-regulatory codes of conduct and guidelines. Failure to adhere to such rules and regulations could result in any number of possible sanctions, including fines and criminal prosecutions as well as reputational damage to us and our products.

Legislative or regulatory reform of the healthcare system may affect our ability to sell our products profitably.

In December 2017, portions of the ACA dealing with the individual mandate insurance requirement were effectively repealed by the Tax Cuts and Jobs Act of 2017, and the U.S. Congress may seek to repeal other aspects of the ACA. In December 2018, a federal district court judge in Texas found the ACA’s individual mandate to be unconstitutional and therefore the entire law to be invalid. In December 2019, the U.S. Court of Appeals for the Fifth Circuit affirmed the ruling regarding the individual mandate but remanded the case to the district court for additional analysis of the question of severability and whether portions of the law remain valid. The case is currently under consideration by the U.S. Supreme Court and a decision is expected by the summer of 2021. In May 2018, the former Trump presidential administration issued "American Patients First," a multi-faceted blueprint to lower drug prices and subsequently took administrative steps to implement the blueprint, including through proposing sweeping demonstration projects aimed at putting downward pressure on drug prices. On November 20, 2020, CMS issued an interim final rule through the CMS Innovation Center whereby Medicare Part B reimbursement for “certain high-cost prescriptions drugs” would be no more than most-favored-nation price (i.e., the lowest price) after adjustments, for a pharmaceutical product that the drug manufacturer sells in a member country of the Organization for Economic Cooperation and Development that has a comparable per-capita gross domestic product. On December 28, 2020, the United States District Court in Northern California issued a nationwide preliminary injunction against implementation of the interim final rule. In addition, members of the U.S. Congress have indicated an interest in legislative measures designed to lower drug costs. The outlook for the healthcare sector is unclear, and we are unable to predict the future course of federal or state healthcare legislation and regulations. The new Biden administration has indicted that lowering prescription drug prices is a priority, but we do not yet know what steps the administration will take or whether such steps will be successful.

51

Healthcare systems outside the U.S. are varied and in the EU differ from country to country. In general, in many EU countries there is a growing pressure to lower overall expenditure on medicines and a range of government initiatives are in place or being proposed with this aim. These include measures to lower the prices of medicines, restrictions on reimbursement, and a range of substitution, procurement and prescribing initiatives. The state of healthcare legislation and regulation in the EU is also unclear and difficult to predict.

Changes in the law or regulatory framework that reduce our revenues or increase our costs could also harm our business, financial condition and results of operations and cash flows.

Our existing or potential products may not be commercially viable in the U.S. if we fail to obtain or maintain an adequate level of reimbursement for these products by Medicaid, Medicare or other third party payers.

Our ability to sell our products in the U.S. and be profitable is substantially dependent on third party payers, such as government or government-sponsored health administrative authorities, including Medicaid and Medicare Parts B and D, private health insurers and other such organizations, agreeing to reimburse patients for the cost of our products. Significant uncertainty exists as to the reimbursement status of newly approved drug products, including Inbrija (levodopa inhalation powder). Third party payers are increasingly challenging the pricing of medical products and services and their reimbursement practices may affect the price levels for Inbrija or other potential products we may develop in the future. Our business could be materially harmed if the Medicaid program, Medicare program or other third party payers were to deny reimbursement for our products or provide reimbursement only on unfavorable terms. Our business could also be harmed if the Medicaid program, Medicare program or other reimbursing bodies or payers limit the indications for which our products will be reimbursed to a smaller set of indications than we believe is appropriate or limit the circumstances under which our products will be reimbursed to a smaller set of circumstances than we believe is appropriate.

Third party payers frequently require that drug companies negotiate agreements with them that provide discounts or rebates from list or wholesale prices. We have agreed to provide such discounts and rebates to some third party payers in relation to Inbrija and Ampyra, and we expect that obtaining agreements with other third party payers to provide access to, and reimburse patients for, our products, if possible, will similarly require that we provide such discounts and rebates. We expect increasing pressure to offer larger discounts and discounts to a greater number of third party payers to maintain acceptable reimbursement levels and access for patients at copay levels that are reasonable. There is no guarantee that we would be able to negotiate agreements with third party payers at price levels that are profitable to us, or at all. Many third party payers have implemented utilization management techniques for Inbrija and Ampyra, such as prior authorization and/or quantity limits. Patients who cannot meet the conditions of prior authorizations are often prevented from obtaining the prescribed medication, because they cannot afford to pay for the medication without reimbursement. If we are unsuccessful in maintaining reimbursement for our products at acceptable levels, or if reimbursement for our products by third party payers is subject to overly restrictive utilization management, our business will be harmed. In addition, if our competitors reduce the prices of their products, or otherwise demonstrate that they are better or more cost effective than our products, this may result in a greater level of reimbursement for their products relative to our products, which would reduce our sales and harm our results of operations. Both federal healthcare programs and commercial insurers are increasingly conditioning coverage, formulary placement, and/or reimbursement rates on the ability of a manufacturer to present favorable health economics and outcomes data.

The Medicare Part D outpatient prescription drug benefit is provided primarily through private entities, which attempt to negotiate price concessions from pharmaceutical manufacturers. These negotiations increase pressure to lower prescription drug prices or increase rebate payments to offset price. While the law specifically prohibits the U.S. government from interfering in price negotiations between manufacturers and Medicare drug plan sponsors, some members of Congress support legislation that would permit the U.S. government to use its enormous purchasing power to demand discounts from pharmaceutical companies. In addition, the ACA contains triggers for Congressional consideration of cost containment measures for Medicare in the event Medicare cost increases exceed a certain level. These cost containment measures could include limitations on prescription drug prices. The ACA requires drug manufacturers to provide a 70% discount on prescriptions for branded products filled while the beneficiary is in the Medicare Part D coverage gap, also known as the “donut hole.” Legislative or regulatory revisions to the Medicare Part D outpatient prescription drug benefit, as well as additional healthcare legislation that may be enacted at a future date, could reduce our sales and harm our results of operations.

52

The success of our existing and potential products in the EU substantially depends on achieving adequate government reimbursement.

The commercial success in the EU of products approved there primarily depends on obtaining and maintaining government reimbursement because, in many European countries, patients may not have access to prescription drugs that are not reimbursed by their governments. In addition, participation in pricing and reimbursement procedures and negotiating prices with government authorities can delay commercialization. Even if reimbursement is available, reimbursement policies may negatively impact revenue from sales of our products and therefore our ability or that of our collaborators, such as Biogen or a future collaborator for Inbrija, to sell our products on a profitable basis. Furthermore, cross-border imports from lower-priced markets (parallel imports) into higher-priced markets could harm sales of products by us or our collaborators and exert commercial pressure on pricing within a country.

Governments in a number of international markets have announced or implemented measures aimed at reducing healthcare costs to constrain the overall level of government expenditures. This includes some of the largest markets in the EU, where Biogen has obtained regulatory approval for Fampyra and countries where we may seek to market Inbrija directly or through a collaborator. The measures vary by country and include, among other things, mandatory rebates and discounts, clinical benefit and cost-effectiveness assessments, reimbursement limitations and reference pricing, price reductions and suspensions on pricing increases on pharmaceuticals. These measures may negatively impact net revenue from Biogen’s sales of Fampyra and therefore both the timing of when, if ever, we receive any further royalty revenue from Biogen under the terms of our Fampyra royalty monetization transaction with HealthCare Royalty Partners, and the amount of the royalty we would then receive from Biogen. Furthermore, the adverse financial impact of these measures in any particular country, in addition to related reimbursement or regulatory constraints, could prevent the commercial launch or continued commercialization of Inbrija or Fampyra in that country.

The United Kingdom’s withdrawal from the European Union, generally referred to as “Brexit,” could make it more difficult for us to do business in Europe or have other adverse effects on our business.

As of January 1, 2021, the UK formally left the EU and the UK and EU are now operating separate pharmaceutical regulatory regimes. The UK and EU announced on December 24, 2020 that they had agreed a Trade and Cooperation Agreement (TCA) to govern their future relationship. The TCA remains provisional until formally ratified by the EU, which is expected to occur in early 2021. The TCA sets out the new arrangements for trade of goods, including medicines and medical devices, which aims to ensure goods continue to flow between the EU and the UK and also has implications for product regulation and mutual recognition.

As a result of the UK’s departure from the EU, the UK Medicines and Healthcare products Regulatory Agency (MHRA) has offered the holders of EU marketing authorizations the option of a UK national marketing authorization to reflect the EU approval. Pursuant to that offer, effective January 1, 2021, Acorda was granted a grandfathered marketing authorization which is subject to certain administrative filings due by December 31, 2021. In order to maintain the grandfathered marketing authorization in the UK, we are required to retain the services of a qualified person for pharmacovigilance. Moreover, if we are to market Inbrija in the UK in the future, the movement of finished pharmaceutical products into the UK is treated as an import from a third country post-Brexit. The UK has decided to unilaterally waive batch testing requirements for imports of products from the EU until January 2023. Unless the UK and EU enter into a mutual recognition agreement or otherwise agree to extend this period, we may face additional quality control and batch release requirements for product entering the UK from the EU after this date.

In addition, although the TCA provides some clarity regarding the future relationship between the EU and UK, the impact of Brexit on the fiscal, monetary and regulatory landscape in the UK remains uncertain, it could have a material impact on its economy and the future growth of its various industries, including the pharmaceutical and biotechnology industries. Given the lack of comparable precedent, it remains unclear what financial, trade, regulatory and legal implications the withdrawal of the UK from the EU may have and how such withdrawal would affect us.

53

If our competitors develop and market products that are more effective, safer or more convenient than our approved products, or obtain marketing approval before we obtain approval of future products, our commercial opportunity will be reduced or eliminated.

Competition in the pharmaceutical and biotechnology industries is intense and is expected to increase. Many biotechnology and pharmaceutical companies, as well as academic laboratories, are engaged in research, development, and/or marketing of therapeutics for various neurological conditions, including Parkinson’s disease and multiple sclerosis.

Our competitors may succeed in developing products that are more effective, safer or more convenient than our products or the ones we have under development or that render our approved or proposed products or technologies noncompetitive or obsolete. In addition, our competitors may achieve product commercialization before we do. If any of our competitors develops a product that is more effective, safer or more convenient for patients, or is able to obtain FDA approval for commercialization before we do, we may not be able to achieve market acceptance for our products, which would harm our ability to generate revenues and recover the substantial development costs we have incurred and will continue to incur.

Our products may be subject to competition from lower-priced versions of such products and competing products imported into the U.S. from Canada, Mexico and other countries where there are government price controls or other market dynamics that cause the products to be priced lower.

Inbrija (levodopa inhalation powder)/Parkinson’s Disease. Inbrija competes against other therapies approved for intermittent, or as needed, use that aim to specifically address Parkinson’s disease symptoms. Apokyn, an injectable formulation of apomorphine, is approved for the treatment of OFF periods, also known as OFF episodes. Apokyn was approved for this use in the U.S. in 2004 and in Europe in 1993. Also, Sunovion Pharmaceuticals Inc. has developed a sublingual, or under the tongue, formulation of apomorphine branded as Kynmobi that is competitive with Inbrija. Sunovion received FDA approval for Kynmobi in May 2020 for the acute, intermittent treatment of OFF episodes, and Kynmobi became available in the U.S. in September 2020.

The standard of care for the treatment of Parkinson’s disease is oral carbidopa/levodopa, but oral medication can be associated with wide variability in the timing and the amount of absorption and there are significant challenges in creating a regimen that consistently maintains therapeutic effects as Parkinson’s disease progresses. Inbrija may face competition from therapies that can limit the occurrence of OFF periods. Approaches to achieve consistent levodopa plasma concentrations include new formulations of carbidopa/levodopa, such as extended-release and intestinal infusions, and therapies that prolong the effect of levodopa. Amneal Pharmaceuticals, Inc. (formerly Impax Laboratories) markets RYTARY, an extended-release formulation of oral carbidopa/levodopa, and extended release formulations of oral and patch carbidopa/levodopa are being developed by others including Intec Pharma and Mitsubishi Tanabe Pharma Corporation. Also, Abbvie Inc. has developed a continuous administration of a gel-containing levodopa through a tube that is surgically implanted into the intestine. This therapy, known as Duopa, has been approved by the FDA and is approved in the EU.

One or more of our competitors may utilize their expertise in pulmonary delivery of drugs to develop and obtain approval for pulmonary delivery products that may compete with Inbrija and any other of our other ARCUS drug delivery technology product candidates. These competitors may include smaller companies such as Alexza Pharmaceuticals, Inc., MannKind Corporation, Pulmatrix, Inc. and Vectura Group plc and larger companies such as Allergan, Inc., GlaxoSmithKline plc and Novartis AG, among others. If approved, our product candidates may face competition in the target commercial areas for these pulmonary delivery products. Also, we are aware that at least one company, Impel Neuropharma, is developing intranasally delivered levodopa therapies which, if approved, might compete with Inbrija.

Ampyra/MS. Ampyra became subject to competition from generic versions of Ampyra starting in late 2018 as a result of an adverse U.S. federal district court ruling that invalidated certain Ampyra Orange Book-listed patents. We have experienced a significant decline in Ampyra sales due to competition from several generic versions of Ampyra. Additional manufacturers may market generic versions of Ampyra, and we expect our Ampyra sales will continue to decline over time.

Current disease management approaches to MS are classified either as relapse management, disease course management, or symptom management approaches. For relapse management, the majority of neurologists treat sudden and severe relapses with a four-day course of intravenous high-dose corticosteroids. Many of these corticosteroids are available generically. For disease course management, there are a number of FDA-approved MS therapies that seek to modify the immune system. These treatments attempt to reduce the frequency and severity of exacerbations or slow the accumulation of physical disability for people with certain types of MS, though their precise mechanisms of action are not known. These

54

products include Avonex, Tysabri, Plegridy and Tecfidera from Biogen, Betaseron from Bayer AG, Copaxone from Teva Pharmaceutical Industries, Ltd., Rebif from Merck Serono, Gilenya and Extavia from Novartis AG, Aubagio and Lemtrada from Genzyme Corporation (a Sanofi company), Glatopa from Sandoz International GmbH (a Novartis AG company), Zinbryta from Biogen and AbbieVie, Rituxan from F. Hoffman-La Roche AG, and Zeposia from BristolMyersSquibb.

Several biotechnology and pharmaceutical companies, as well as academic laboratories, are involved in research and/or product development for various neurological diseases, including MS. Other companies also have products in clinical development, including products approved for other indications in MS, to address improvement of walking ability in people with MS. Furthermore, several companies are engaged in developing products that include novel immune system approaches and cell therapy approaches to remyelination for the treatment of people with MS. These programs are in early stages of development and may compete in the future with Ampyra or some of our product candidates. In addition, in certain circumstances, pharmacists are not prohibited from formulating certain drug compounds to fill prescriptions on an individual patient basis, which is referred to as compounding. We are aware that at present compounded dalfampridine is used by some people with MS and it is possible that some people will want to continue to use compounded formulations even though Ampyra and generic versions of Ampyra are commercially available.

State pharmaceutical compliance and reporting requirements may expose us to regulatory and legal action by state governments or other government authorities.

Many states have enacted laws governing the licensure of companies that manufacture and/or distribute prescription drugs, although the scope of these laws varies, particularly where out-of-state distributors are concerned. We have obtained licenses in all of the jurisdictions in which we believe we are required to be licensed. However, there can be no assurance that one or more of these states will not take action under these licensure laws.

Several states have also enacted legislation regarding promotional and other activities conducted by pharmaceutical companies. The specifics of these laws vary, but in general they require companies to establish marketing compliance programs; disclose various sales and marketing expenses and pricing information; refrain from providing certain gifts or other payments to healthcare providers; and/or ensure that their sales representatives in that state are licensed. Some states, including California, Connecticut, Massachusetts, Minnesota, and Vermont, and the District of Columbia have passed laws of varying scope that ban or limit the provision of gifts, meals and certain other payments to healthcare providers and/or impose reporting and disclosure requirements upon pharmaceutical companies pertaining to drug pricing, payments and/or costs associated with pharmaceutical marketing, advertising and other promotional activities. Other states also have laws that regulate, directly or indirectly, various pharmaceutical sales and marketing activities, and new legislation is being considered in many states.

Many of the state requirements continue to evolve, and the manner in which they will be enforced going forward is uncertain. In some cases, the penalties for failure to comply with these requirements are unclear. We are continually updating our compliance infrastructure and standard operating procedures to comply with such laws, but we cannot eliminate the risk created by these uncertainties. Unless we are in full compliance with these laws, we could face enforcement action, fines and other penalties, including government orders to stop selling drugs into a state until properly licensed, and could receive adverse publicity.

Our inability to attract and retain key management and other personnel, or maintain access to expert advisors, may hinder our ability to execute our business plan.

We are highly dependent on the services of Dr. Ron Cohen, our President and Chief Executive Officer, as well as the other principal members of our management and scientific, regulatory, manufacturing and commercial personnel. Our success depends in large part upon our ability to attract and retain highly qualified personnel with the knowledge and experience needed for these and other areas of our business. We do not maintain "key man" life insurance policies on the lives of our officers, directors or employees.

We face intense competition in our hiring efforts with other pharmaceutical and biotechnology companies, as well as universities and nonprofit research organizations, and we may have to pay higher salaries to attract and retain qualified personnel. In addition, recent developments with our business, including the adverse patent decision relating to our Orange Book-listed Ampyra patents, the termination or suspension of research and development programs, reductions in force in connection with corporate restructurings, and the current progress of our Inbrija commercial launch, may impede our ability to attract and retain highly qualified personnel. The loss of one or more of our key employees, the loss of multiple employees

55

in particular functions, and/or our inability to attract replacement or additional qualified personnel, could substantially impair our ability to implement our business plan, particularly our efforts to successfully commercialize Inbrija. We have recently experienced workforce attrition in various functions across our business, which may be attributable to one or more of the factors described above, and we may not be able to adjust our operations in response to prevent disruption to our business. Also, due to the recent attrition, three reductions in force since 2017, and our 2021 sale of our Chelsea manufacturing operations, we believe we lack personnel needed for, and would need to hire replacements before continuing with, research and development and clinical programs. Our inability to attract qualified replacements needed for research and development and clinical programs could substantially impair our ability to advance those programs, if we determine to make further investments in those programs.

We also have scientific, medical, clinical, marketing and other advisors who assist us in our research and development, clinical, and commercial strategies. These advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us. Similarly, they may have arrangements with other companies to assist in the development and commercialization of products that may compete with ours.

We and our third party contract manufacturers must comply with environmental, health and safety laws and regulations, and failure to comply with these laws and regulations could expose us to significant costs or liabilities.

Biopharmaceutical research and development activities are subject to numerous and increasingly stringent environmental, health and safety laws and regulations, including those which govern laboratory procedures and the use, generation, manufacture, distribution, storage, handling, treatment, remediation and disposal of hazardous substances. Also, we operate a manufacturing facility, which is subject to further environmental, health and safety laws and regulations, including those laws and regulations which govern the exposure of persons to hazardous substances, the emission of pollutants into the air, the discharge of pollutants into bodies of water, and the general health, safety and welfare of employees and members of the public. We may incur substantial costs in order to comply with current or future such laws and regulations, which may also impair our research, development and/or manufacturing efforts.

In connection with research and development and manufacturing activities, we cannot completely avoid the risk of contamination or injury, and in such cases of contamination or injury, or in cases of failure to comply with environmental, health and safety laws and regulations, we could be held liable, and in some cases strictly liable, for any resulting damages. Moreover, the existence, investigation and/or remediation of contamination at properties currently or formerly owned, leased or operated by us may result in costs, fines or other penalties. Furthermore, our third party manufacturers are subject to the same or similar environmental, health and safety laws and regulations as those to which we are subject. It is possible that if our third party manufacturers fail to operate in compliance with the applicable environmental, health and safety laws and regulations or properly dispose of wastes associated with our products, we could be held liable for any resulting damages and/or experience a disruption in the manufacture and supply of our product candidates or products. Any such liability may result in substantial civil or criminal fines, penalties or other sanctions, which could exceed our assets and resources, as well as reputational harm.

Risks related to our intellectual property

If we cannot protect, maintain and, if necessary, enforce our intellectual property, our ability to develop and commercialize our products will be severely limited.

Our success will depend in part on our and our licensors' ability to obtain, maintain and enforce patent and trademark protection for the technologies, compounds and products, if any, resulting from our licenses and research and development programs. Without protection for the intellectual property we use or intend to use, other companies could offer substantially identical products for sale without incurring the sizable discovery, research, development and licensing costs that we have incurred. Our ability to recover these expenditures and realize profits upon the sale of products could be diminished.

We have patent portfolios relating to Inbrija (levodopa inhalation powder), our ARCUS drug delivery technology, cimaglermin alfa/neuregulins, and remyelinating antibodies/antibodies relating to nervous system disorders, composed of both our own and in-licensed patents and patent applications. For some of our proprietary technologies, for example our ARCUS drug delivery technology, we rely on a combination of patents, trade secret protection and confidentiality agreements to protect our intellectual property rights. Our intellectual property also includes copyrights and a portfolio of trademarks.

56

The process of obtaining patents and trademarks can be time consuming and expensive with no certainty of success. Even if we spend the necessary time and money, a patent or trademark may not issue, it may not issue in a timely manner, or it may not have sufficient scope or strength to protect the technology it was intended to protect or to provide us with any commercial advantage. We may never be certain that we were the first to develop the technology or that we were the first to file a patent application for the particular technology because patent applications are confidential until they are published, and publications in the scientific or patent literature lag behind actual discoveries. The degree of future protection for our proprietary rights will remain uncertain if our pending patent applications are not allowed or issued for any reason or if we are unable to develop additional proprietary technologies that are patentable. Furthermore, third parties may independently develop similar or alternative technologies, duplicate some or all of our technologies, design around our patented technologies or challenge our issued patents or trademarks or the patents or trademarks of our licensors. For example, Ampyra became subject to competition from generic versions of Ampyra starting in late 2018 as a result of an adverse U.S. federal district court ruling that invalidated certain Ampyra Orange Book-listed patents. We have experienced a significant decline in Ampyra sales due to competition from several generic versions of Ampyra. Additional manufacturers may market generic versions of Ampyra, and we expect our Ampyra sales will continue to decline over time.

Also, the validity of our patents can be challenged by third parties pursuant to procedures introduced by American Invents Act, specifically inter partes review and/or post grant review before the U.S. Patent and Trademark Office. For example, in 2015, a hedge fund (acting with affiliated entities and individuals and proceeding under the name of the Coalition for Affordable Drugs) filed inter partes review (IPR) petitions with the U.S. Patent and Trademark Office, challenging some of our Ampyra Orange Book-listed patents. We successfully defended the patents in these proceedings, but this outcome did not affect the U.S. federal district court decision invalidating Ampyra Orange Book-listed patents as described above. IPR petitions could be filed in the future challenging our other patents for any of our programs.

Patent litigation, IPR proceedings, and other legal proceedings involve complex legal and factual questions. We need to devote significant resources to the existing ANDA and IPR legal proceedings, and we may need to devote significant resources to other legal proceedings that arise in the future. If we are not successful, we could lose some or all of our Orange Book listed patents and our business could be materially harmed. We can provide no assurance concerning the duration or the outcome of any such lawsuits and legal proceedings.

We may initiate actions to protect our intellectual property (including, for example, in connection with the filing of an ANDA as described above) and in any litigation in which our intellectual property or our licensors' intellectual property is asserted, a court may determine that the intellectual property is invalid or unenforceable. Even if the validity or enforceability of that intellectual property is upheld by a court, a court may not prevent alleged infringement on the grounds that such activity is not covered by, for example, the patent claims. In addition, effective intellectual property enforcement may be unavailable or limited in some foreign countries for a variety of legal and public policy reasons. From time to time we may receive notices from third parties alleging infringement of their intellectual property rights. Any litigation, whether to enforce our rights to use our or our licensors' patents or to defend against allegations that we infringe third party rights, would be costly, time consuming, and may distract management from other important tasks.

As is commonplace in the biotechnology and pharmaceutical industry, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. To the extent our employees are involved in areas that are similar to those areas in which they were involved at their former employers, we may be subject to claims that such employees and/or we have inadvertently or otherwise used or disclosed the alleged trade secrets or other proprietary information of the former employers. Litigation may be necessary to defend against such claims, which could result in substantial costs and be a distraction to management and which could have an adverse effect on us, even if we are successful in defending such claims.

We also rely in our business on trade secrets, know-how and other proprietary information. For example, the know-how that forms the basis of our proprietary manufacturing process for the ARCUS technology and Inbrija manufacturing is substantially dependent on trade secret protection. We seek to protect this information, in part, through the use of confidentiality agreements with employees, consultants, collaborators, advisors and others. Nonetheless, those agreements may not provide adequate protection for our trade secrets, know-how or other proprietary information, including our proprietary ARCUS technology, and prevent their unauthorized use or disclosure. To the extent that consultants, collaborators, key employees or other third parties apply technological information independently developed by them or by others to our proposed products, joint ownership may result, which could undermine the value of the intellectual property to us or disputes may arise as to the proprietary rights to such information which may not be resolved in our favor. The risk that other parties may breach confidentiality agreements or that our trade secrets such as our ARCUS technology become known or independently discovered by competitors, could harm us by enabling our competitors, who may have greater experience

57

and financial resources, to copy or use our trade secrets and other proprietary information in the advancement of their products, methods or technologies. Policing unauthorized use of our or our licensors' intellectual property is difficult, expensive and time-consuming, and we may be unable to determine the extent of any unauthorized use. Adequate remedies may not exist in the event of unauthorized use or disclosure.

Our business could be harmed by requirements to publicly disclose our clinical trial data.

There is an increasing trend across multiple jurisdictions, including the United States and the EU, towards requiring greater transparency, particularly in the area of clinical trial results. In many jurisdictions, including the U.S. and the EU, we are required to register most of our clinical trials as well as disclose summaries of the results of those clinical trials. Further requirements for transparency could result in the disclosure of data down to the individual patient level. In the EU, for example, the European Medicines Agency, or EMA, has since 2015 implemented a policy on transparency of clinical trial data submitted to the agency in applications for marketing authorization. These data traditionally were regarded as confidential commercial information not subject to disclosure. According to this policy, the EMA proactively publishes anonymized clinical data submitted by pharmaceutical companies to support their regulatory applications submitted after January 1, 2015 (subject to certain company redactions agreed with the EMA during the application review process). Possible redactions include commercially confidential information, identifiable information about study participants and study staff and patient level data (i.e., line listings including patient data against individual patient codes). The EMA plans to release patient level data in the future, but needs to address some data privacy concerns before doing so. The EMA may release clinical data submitted before this date on request, subject to the company having the opportunity to make similar redactions. The precise implementation of the EMA’s policy remains in flux and subject to legal challenge. This could harm our business in a variety of ways, including for example through disclosure of our trade secret methodologies for clinical development of our products, and/or by potentially enabling competitors to use our clinical data to gain approvals for their own products in the same or other jurisdictions. Regardless of the precise details of the EMA’s policy, the trend across governments is for increased transparency, which could diminish our ability to protect our confidential commercial information.

If third parties successfully claim that we infringe their patents or proprietary rights, our ability to continue to develop and successfully commercialize our product candidates could be delayed or prevented.

Third parties may claim that we or our licensors or suppliers are infringing their patents or are misappropriating their proprietary information. In the event of a successful claim against us or our licensors or suppliers for infringement of the patents or proprietary rights of others relating to any of our marketed products or product candidates, we may be required to:

In addition, from time to time, we may become aware of third parties who have, or claim to have, intellectual property rights covering matters such as methods for doing business, conducting research, diagnosing diseases or prescribing medications that are alleged to be broadly applicable across sectors of the industry, and we may receive assertions that these rights apply to us. The existence of such intellectual property rights could present a risk to our business.

A license required under any patents or proprietary rights held by a third party may not be available to us, or may not be available on acceptable terms. If we or our licensors or suppliers are sued for infringement we could encounter substantial delays in, or be prohibited from developing, manufacturing and commercializing our product candidates and advancing our preclinical or clinical programs. In addition, any such litigation would be costly, time consuming, and might distract management from other important tasks.

58

We are dependent on our license agreements and if we fail to meet our obligations under these license agreements, or our agreements are terminated for any reason, we may lose our rights to our in-licensed patents and technologies.

We are dependent on licenses for intellectual property for products and research and development programs, including in particular Inbrija and our ARCUS based programs. Our failure to meet any of our obligations under these license agreements could result in the loss of our rights to this intellectual property. If we lose our rights under any of these license agreements, we may be unable to commercialize, or continue commercializing, a product that uses licensed intellectual property.

Risks relating to our common stock  

Our stock price may be volatile and you may lose all or a part of your investment.

Our stock price could fluctuate significantly due to a number of factors, including:

Many of these factors are beyond our control, and we believe that period-to-period comparisons of our financial results will not necessarily be indicative of our future performance. If our revenues in any particular period do not meet expectations, we may not be able to adjust our expenditures in that period, which could cause our operating results to suffer. If our operating results in any future period fall below the expectations of securities analysts or investors, our stock price may fall by a significant amount.

In addition, the stock markets in general, and the Nasdaq Global Market and the market for biopharmaceutical companies in particular, have recently and can in the future experience extreme price and volume fluctuations. These fluctuations often have been unrelated or disproportionate to the operating performance of these companies. These broad market and industry factors may adversely affect the market price of our common stock, regardless of our actual operating performance.

59

We cannot predict the effect that our reverse stock split will have on the market price for shares of our common stock.

We completed a one-for-six reverse stock split on December 31, 2020. We cannot predict the long-term effect of the reverse stock split upon the market price for shares of our common stock, and the history of similar reverse stock splits for companies in like circumstances has varied. Although the reverse stock split initially resulted in an increased market price per share of our common stock, the market price per share may not increase in proportion to the reduction of the number of shares of our common stock outstanding before the implementation of the reverse stock split, or remain at current levels due to, among other factors, the performance of our business, economic conditions and other factors, some of which may not be under our control. Accordingly, even with an increased market price per share, the total market capitalization of shares may be lower than the total market capitalization before the reverse stock split.

If the market price of shares of our common declines, the percentage decline may be greater than would have occurred in the absence of the reverse stock split due to decreased liquidity in the market for our common stock. Accordingly, the percentage decline as an absolute number and as a percentage of our overall market capitalization may be greater than would have occurred in the absence of the reverse stock split. This would result in the market capitalization of our common stock following the reverse stock split being lower than the total market capitalization before the reverse stock split.

Future sales of our common stock could cause our stock price to decline, and future issuances of common stock could cause substantial dilution.

If our existing stockholders sell a large number of shares of our common stock, or the public market perceives that existing stockholders might sell shares of common stock, the market price of our common stock could decline significantly. Sales of substantial amounts of shares of our common stock in the public market by our executive officers, directors, 5% or greater stockholders or other stockholders, or the prospect of such sales, could adversely affect the market price of our common stock. As of March 4, 2021, 9,489,873 shares of our common stock were issued and outstanding; options to acquire 1,235,904 shares of our common stock were outstanding, exercisable at an average exercise price of $128.40 per share, issued under our 2006 Employee Incentive Plan or our 2015 Omnibus Incentive Compensation Plan; and restricted stock units issued under our 2015 Omnibus Incentive Compensation Plan entitling the holders to an aggregate of 19,163 shares of our common stock were outstanding. Additional shares of common stock are authorized for issuance pursuant to options and other stock-based awards under our 2015 Omnibus Incentive Compensation Plan and under our 2019 Employee Stock Purchase Plan, and additional stock-based awards could be issued under our 2016 Inducement Plan. To the extent that option holders exercise outstanding options, there may be further dilution and the sales of shares issued upon such exercises could cause our stock price to drop further. In addition, if we elect to settle all or a portion of our conversion or make-whole payment obligations under, and/or interest payments on, our convertible senior secured notes due 2024, our stockholders could experience significant dilution. Lastly, in January 2021, we entered into an At The Market (ATM) Offering Agreement with H.C. Wainwright & Co., LLC as sales agent. Pursuant to the ATM agreement, we may offer and sell shares of our common stock having an aggregate value of up to $15.25 million in an at-the-market offering, which could cause additional dilution.

If our officers, directors and largest stockholders choose to act together, they may be able to control the outcome of stockholder vote.

Our officers, directors and current holders of 5% or more of our outstanding common stock beneficially owned a significant portion of our common stock. As a result, these stockholders, acting together, will be able to significantly influence all matters requiring approval by our stockholders, including the election of directors and the approval or mergers or other business combination transactions. The interests of this group of stockholders may not always coincide with the interests of other stockholders, and they may act in a manner that advances their best interests and not necessarily those of other stockholders.

Certain provisions of Delaware law, our Certificate of Incorporation, and our Bylaws may delay or prevent an acquisition of us that stockholders may consider favorable or may prevent efforts by our stockholders to change our directors or our management, which could decrease the value of your shares.

Our Certificate of Incorporation and Bylaws contain provisions that could make it more difficult for a third party to acquire us, and may have the effect of preventing or hindering any attempt by our stockholders to replace our current directors or officers. These provisions include:

60

As a Delaware corporation, we are also subject to certain anti-takeover provisions of Delaware law. Under Delaware law, a corporation may not engage in a business combination with any holder of 15% or more of its capital stock unless the holders has held the stock for three years or, among other things, the board of directors has approved the transaction. Our board of directors could rely on Delaware law to prevent or delay an acquisition of us, which could have the effect of reducing your ability to receive a premium on your common stock.

Because we do not intend to pay dividends in the foreseeable future, you will benefit from an investment in our common stock only if it appreciates in value.

We have not paid cash dividends on any of our classes of capital stock to date, and we currently intend to retain our future earnings, if any, to fund the development and growth of our business. As a result, we do not expect to pay any cash dividends in the foreseeable future. The success of your investment in our common stock will depend entirely upon any future appreciation. There is no guarantee that our common stock will appreciate in value or even maintain the price at which you purchased your shares.

General Risk Factors

Our ability to use net operating loss carry forwards to reduce future tax payments may be limited if taxable income does not reach sufficient levels or if there is a change in ownership of Acorda.

In general, under the Internal Revenue Code of 1986, as amended (the “Code”), a corporation is subject to limitations on its ability to utilize net operating losses, or NOLs, to offset future taxable income. As of December 31, 2020, we had approximately $162.1 million of U.S. Federal NOLs. Existing NOLs that were incurred prior to 2018 have a 20 year carryforward available (based on when they were incurred) to reduce taxable income in future years. Federal income tax losses generated in tax years ending after January 1, 2018 can generally be carried forward indefinitely, due to 2017 tax reform legislation. However, the ability to use existing NOL carryforwards will be dependent on our ability to generate taxable income and will be subject to an annual limitation of 80% of taxable income. Of our existing NOLs, approximately

61

$121.4 million existed at December 31, 2020 and were incurred by our Biotie subsidiary. Our ability to use these Biotie NOL carryforwards will depend on the ability of that specific subsidiary to generate taxable income, and because we do not expect any taxable income from that subsidiary we currently do not assign any value to these NOLs. The remaining U.S. Federal NOL carryforward as of December 31, 2020 of approximately $40.7 million is for the Acorda Therapeutics, Inc. return filing group, which is carried forward indefinitely and subject to the 80% limitation on taxable income when utilized in future tax years.

Our ability to utilize the NOL's may be further limited if we undergo an ownership change, as defined in section 382 of the Code. This ownership change could be triggered by substantial changes in the ownership of our outstanding stock, which are generally outside of our control. An ownership change would exist if the stockholders, or group of stockholders, who own or have owned, directly or indirectly, 5% or more of the value of our stock, or are otherwise treated as 5% stockholders under section 382 and the regulations promulgated thereunder, increase their aggregate percentage ownership of our stock by more than 50 percentage points over the lowest percentage of our stock owned by these stockholders at any time during the testing period, which is generally the three-year period preceding the potential ownership change. In the event of an ownership change, section 382 imposes an annual limitation on the amount of post-ownership change taxable income a corporation may offset with pre-ownership change NOL's. If an ownership change were to occur, the annual limitation under Section 382 could result in a material amount of our NOLs expiring unused. This could significantly impair any value we assign to our NOL asset and, as a result, could have a negative impact on our financial position and results of operations.

We may have exposure to additional tax liabilities, which could have a material impact on our results of operations and financial position.

We are subject to income taxes, as well as non-income based taxes, in both the U.S. and Puerto Rico, as well as certain European countries where we have subsidiaries and/or subsidiary operations. Significant judgment is required in determining our tax liabilities. Although we believe our estimates are reasonable, the ultimate outcome with respect to the taxes we owe may differ from the amounts recorded in our financial statements. If the Internal Revenue Service, or other taxing authority, disagrees with the positions taken by us, we could have additional tax liability, and this could have a material impact on our results of operations and financial position. In addition, governments may adopt tax reform measures that significantly increase our worldwide tax liabilities, which could materially harm our business, financial condition and results of operations.

We may expand our business through the acquisition of companies or businesses or in-licensing product candidates that could disrupt our business and harm our financial condition.

We may in the future seek to expand our products and capabilities by acquiring one or more companies or businesses or in-licensing one or more product candidates. Acquisitions and in-licenses involve numerous risks, including:

62

We cannot assure you that any acquisition or in-license will result in short-term or long-term benefits to us. We may incorrectly judge the value or worth of an acquired company or business or in-licensed products or product candidates, for example by underestimating the investment required to advance research and development programs, or overestimating approvability by the FDA or the market potential of acquired or in-licensed products or product candidates. Acquired development programs are generally subject to all of the risks inherent in the drug development process, and our knowledge of the risks specifically relevant to acquired programs generally improves over time.

In addition, our future success would depend in part on our ability to manage the rapid growth associated with some of these acquisitions and in-licenses. Any acquisition might distract resources from and otherwise harm sales of Inbrija or other products we currently, or may in the future, market. We cannot assure you that we would be able to make the combination of our business with that of acquired businesses or companies or in-licensed products or product candidates work or be successful. Furthermore, the development or expansion of our business or any acquired business or company or in-licensed product or product candidate may require a substantial capital investment by us. We may not have these necessary funds or they might not be available to us on acceptable terms or at all. We may also seek to raise funds by selling shares of our stock, which could dilute our current stockholders’ ownership interest, or securities convertible into our stock, which could dilute current stockholders’ ownership interest upon conversion. Also, although we may from time to time announce that we have entered into agreements to acquire other companies or assets, we cannot assure you that these acquisitions will be completed in a timely manner or at all. These transactions are subject to an inherent risk that they may not be completed, for example because required closing conditions cannot be met at all or within specified time periods, termination rights may be exercised such as due to a breach by one of the parties, or other contingencies may arise that affect the transaction.

We face an inherent risk of liability in the event that the use or misuse of our products results in personal injury or death.

If the use or misuse of Inbrija (levodopa inhalation powder), Ampyra or any other approved products we may sell in the future harms people, we may be subject to costly and damaging product liability claims brought against us by consumers, healthcare providers, pharmaceutical companies, third party payers or others. The use of our product candidates in clinical trials could also expose us to product liability claims. We currently maintain a product liability insurance policy that includes coverage for our marketed products as well as for our clinical trials. The total insurance limit is $50 million per claim, and the aggregate amount of claims under the policy is also capped at $50 million. We cannot predict all of the possible harms or side effects that may result from the use of our products or the testing of product candidates and, therefore, the amount of insurance coverage we currently have may not be adequate to cover all liabilities or defense costs we might incur. A product liability claim or series of claims brought against us could give rise to a substantial liability that could exceed our resources. Even if claims are not successful, the costs of defending such claims and potential adverse publicity could be harmful to our business.

Additionally, we have entered into various agreements where we indemnify third parties such as manufacturers and investigators for certain product liability claims related to our products. These indemnification obligations may require us to pay significant sums of money for claims that are covered by these indemnification obligations.

We may be the subject of litigation, which, if adversely determined, could harm our business and operating results.

From time to time, we may be subject to a variety of claims and lawsuits. The costs of defending any litigation, whether in cash expenses or in management time, could harm our business and materially and adversely affect our operating results and cash flows, even if we ultimately win the litigation. An unfavorable outcome on any litigation matter could require that we pay substantial damages, or, in connection with any intellectual property infringement claims, could require that we pay ongoing royalty payments or prohibit us from selling certain of our products. In addition, we may decide to settle any litigation, which could cause us to incur significant settlement costs. A settlement or an unfavorable outcome on any litigation matter could have a material and adverse effect on our business, operating results, financial condition and cash flows.

We depend on sophisticated information technology systems to operate our business and a cyber attack or other breach of these systems, or a system error, could have a material adverse effect on our business and results of operations.

We are increasingly dependent upon information technology systems and infrastructure to operate our business. In the ordinary course of our business, we collect, store, process and transmit sensitive data on our networks and systems, including our intellectual property and proprietary or confidential business information (such as research data) and confidential information (and personal information) with respect to our employees, customers, clinical trial patients and our business

63

partners. In the ordinary course of our business, this type of data is also collected, stored, processed and transmitted on the networks and systems of our business partners and vendors from whom we purchase software and/or technology-based services.

The size and complexity of our and any third party information technology systems and infrastructure, and their connection to the Internet, make such systems potentially vulnerable to service interruptions, system errors leading to data loss, data theft and/or cyber attacks. These incidents could result from inadvertent or intentional actions or omissions by our employees and consultants, or those of our business partners and vendors, or from the actions of third parties with malicious or criminal intent. To date, we have not experienced any material impact to our business or operations resulting from any of these occurrences affecting our or third party information technology systems; however, there is a growing risk of harm from these types of incidents because of the rapid evolution of information technology systems, and because cyber attacks are increasing in frequency and in sophistication over time.

Data breaches or unauthorized data access or disclosure of our confidential information could compromise our intellectual property and expose sensitive business information. A data security breach could also lead to public exposure of personal information of our clinical trial patients, employees and others. Any such event that leads to unauthorized access, use or disclosure of personal information, including personal information regarding our patients or employees, could harm our reputation and business, compel us to comply with federal and/or state breach notification laws and foreign law equivalents, subject us to mandatory corrective action, require us to verify the correctness of database contents and otherwise subject us to liability under laws and regulations that protect the privacy and security of personal information, which could disrupt our business, result in increased costs or loss of revenue, and/or result in significant legal and financial exposure. Data breaches or unauthorized data access could cause us to incur significant remediation costs, result in product development delays, disrupt key business operations and divert attention of management and key information technology resources. Data breaches or unauthorized data access could also result in liability to others, if these incidents involve the data of others that we have agreed, or are otherwise legally responsible, to keep confidential and protect.

Data breaches and unauthorized data access can be difficult to detect, and any delay in identifying any such incidents may lead to increased harm of the type described above. While we have implemented security measures to protect our information technology systems and infrastructure, and monitor such systems and infrastructure on an ongoing basis for any current or potential threats, there can be no assurance that these measures will prevent the type of incidents that could have a material adverse effect on our business and results of operations. Also, we rely on the security measures and monitoring activities of our business partners and vendors who may collect, store, process and transmit data on their networks and systems. In the event they experience a service issue or security incident: we may not receive timely notice from them of the issue or incident; they may not take adequate steps to remediate the issue or incident and protect against future occurrences; we may not have any remedy against them for losses and liabilities that we suffer, or if we have a remedy it may be inadequate, even though they are or may be at fault; and we may become subject to legal claims from others whose information has been compromised regardless of whether we are at fault.

Item 1B. Unresolved Staff Comments.

Item 2. Properties.

Ardsley, New York

In June 2011, we entered into a 15-year lease for an aggregate of approximately 138,000 square feet of office and laboratory space in Ardsley, New York. We relocated our headquarters to this facility in July 2012. In 2014, we exercised our option to expand into an additional 25,405 square feet of office space, which we occupied in January 2015. We have options to extend the term of the lease for three additional five-year periods, and we have an option to terminate the lease after 10 years subject to payment of an early termination fee. Our extension and early termination rights are subject to specified terms and conditions, including specified time periods when they must be exercised, and are also subject to limitations including that we not be in default under the lease.

The Ardsley lease provides for monthly payments of rent during the term. These payments consist of base rent, which takes into account the costs of the facility improvements funded by the facility owner prior to our occupancy, and additional rent covering customary items such as charges for utilities, taxes, operating expenses, and other facility fees and charges. Our

64

base rent is currently $4.9 million per year, which reflects an annual 2.5% escalation factor as well as our expansion, described above.

Chelsea, Massachusetts

Through our Civitas subsidiary, we previously leased a manufacturing facility in Chelsea, Massachusetts which we used to manufacture Inbrija. In February 2021, in connection with the sale of our Chelsea manufacturing operations to Catalent Pharma Solutions, Inc., Civitas assigned the lease of this facility to a Catalent affiliate. At the same time, we entered into a long-term, global manufacturing services (supply) agreement with Catalent pursuant to which they have agreed to manufacture Inbrija for us at the Chelsea facility.

Additional Facilities

In October 2016, we entered into a 10-year lease agreement commencing in January 2017 for approximately 26,000 square feet of lab and office space in Waltham, MA. We entered into this lease primarily to relocate certain personnel from our Chelsea, Massachusetts facility to enable the expansion of manufacturing operations in Chelsea. The base rent under the lease is currently $1.1 million per year.

Item 3. Legal Proceedings.

From time to time, we may be involved in litigation or other legal proceedings relating to claims arising out of operations in the normal course of our business, including the DRI matter described below. The outcome of litigation and other legal proceedings is unpredictable, and regardless of outcome, they can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

On November 9, 2020, Drug Royalty III, L.P., and LSRC III S.ar.l. (collectively, “DRI”) filed an arbitration claim against us with the American Arbitration Association under a September 26, 2003 License Agreement that we originally entered into with Rush-Presbyterian St. Luke’s Medical Center (“Rush”). DRI previously purchased license royalty rights under the license agreement from Rush. DRI alleges a dispute over the last-to-expire patent covering sales of the drug Ampyra under the license agreement, and is claiming damages based on unpaid license royalties of $6 million plus interest. We believe we have valid defenses against this claim and intend to defend ourselves vigorously.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

Our common stock is quoted on the Nasdaq Global Select Market under the symbol “ACOR.”

On December 31, 2020, we filed an amendment to our Certificate of Incorporation which effected, as of 4:01 p.m. Eastern Time on December 31, 2020, a 1-for-6 reverse stock split of the shares of our outstanding common stock and proportionate reduction in the number of authorized shares of our common stock from 370,000,000 to 61,666,666. Our common stock began trading on a split-adjusted basis on The Nasdaq Global Select Market commencing upon market open on January 4, 2021. The common stock continued to trade under the symbol “ACOR” after the reverse stock split became effective. The reverse stock split applied equally to all outstanding shares of the common stock and did not modify the rights or preferences of the common stock. As such, all figures in this report relating to shares of our common stock (such as share amounts, per share amounts, and conversion rates and prices), including in the financial statements and accompanying notes to the financial statements, have been retroactively restated to reflect the 1-for-6 reverse stock split of our common stock.

Computershare is the transfer agent and registrar for our common stock. As of March 4, 2021, we had 16 registered holders of record of our common stock.

Dividend Policy

We have never declared or paid cash dividends on our common stock. We do not anticipate paying any cash dividends on our capital stock in the foreseeable future. We currently intend to retain all available funds and any future earnings to fund the development and growth of our business.

Unregistered Sales of Securities

In December 2020, we issued to the holders of our 6.00% Convertible Senior Secured Notes due 2024 an aggregate of 1,484,871 shares of the Company’s common stock, in satisfaction of approximately $6.2 million in interest due under the 2024 convertible notes on December 1, 2020. Pursuant to the indenture under which the 2024 Notes were issued, we may elect to pay interest in cash or shares of our common stock based on the formula set forth in the indenture, subject to conditions specified therein. In connection with the issuance of the shares, an amount corresponding to the $6.2 million of accrued interest was released from escrow and became available to the Company for other purposes. The issuance of the Shares was exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933.

Issuer Purchases of Equity Securities

Acorda has not announced any plans or programs for the repurchase of its Common Stock. The following table provides information about our purchases of shares of Acorda stock during the three-month period ended December 31, 2020.

(1)Share repurchases reported in this column consist of shares of Acorda’s common stock withheld from employees in November 2020 to cover tax liability in connection with the settlement of restricted stock units (1,359 shares) and shares of Acorda’s common stock tendered by employees in December 2020 to cover taxes relating to the vesting of restricted stock awards (659 shares).

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our consolidated financial condition and results of operations should be read in conjunction with our audited consolidated financial statements and related notes included in this Annual Report on Form 10-K.

Background

We are a biopharmaceutical company focused on developing therapies that restore function and improve the lives of people with neurological disorders. We market Inbrija (levodopa inhalation powder), which is approved in the U.S. for intermittent treatment of OFF episodes, also known as OFF periods, in people with Parkinson’s disease treated with carbidopa/levodopa. Inbrija is for as needed use and utilizes our ARCUS pulmonary delivery system, a technology platform designed to deliver medication through inhalation that we believe has potential to be used in the development of a variety of inhaled medicines. We also market branded Ampyra (dalfampridine) Extended Release Tablets, 10 mg.

Inbrija

Our New Drug Application, or NDA, for Inbrija was approved by the U.S. Food and Drug Administration, or FDA, on December 21, 2018. The approval is for a single dose of 84 mg (administered as two capsules), which may be taken up to five times per day. Inbrija became commercially available in the U.S. on February 28, 2019. Currently, Inbrija is available in the U.S. without the need for a medical exception for approximately 96% of commercial health insurance plan and approximately 25% of Medicare plan lives. Approximately one million people in the U.S. and 1.2 million Europeans are diagnosed with Parkinson’s; it is estimated that approximately 40% of people with Parkinson’s in the U.S. experience OFF periods. Net revenue for Inbrija was $24.2 million for the year ended December 31, 2020. We project peak U.S. annual net revenue of Inbrija to be in the range of $300 to $500 million.

In September 2019, we announced that the European Commission, or EC, approved our Marketing Authorization Application, or MAA, for Inbrija. The approved dose is 66 mg (administered as two capsules) up to five times per day (per European Union, or EU, convention, this reflects emitted dose and is equivalent to the 84 mg labelled dose in the U.S.). Under the MAA, Inbrija is indicated in the EU for the intermittent treatment of episodic motor fluctuations (OFF episodes) in adult patients with Parkinson’s disease treated with a levodopa/dopa-decarboxylase inhibitor. Following the ratification of the Withdrawal Agreement between the United Kingdom and the EU, the UK left the EU on January 31, 2020. Effective January 1, 2021, Acorda was granted a grandfathered Marketing Authorization (MA) by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK which is subject to certain administrative filings that are due by December 31, 2021. We are in discussions with potential partners regarding the distribution of Inbrija outside of the U.S., with potential partners in Europe and Japan.

Ampyra

Ampyra became subject to competition from generic versions of Ampyra starting in late 2018 as a result of an adverse U.S. federal district court ruling that invalidated certain Ampyra Orange Book-listed patents. We have experienced a significant decline in Ampyra sales due to competition from several generic versions of Ampyra. Additional manufacturers may market generic versions of Ampyra, and we expect our Ampyra sales will continue to decline over time. Net revenue for Ampyra was $98.1 million for the year ended December 31, 2020.

On October 30, 2020, we received a $15 million milestone payment from Biogen International GmbH under our license and collaboration with Biogen. Biogen markets Ampyra outside the U.S. as Fampyra. We became entitled to the milestone payment based on Biogen’s ex-U.S. net sales of Fampyra exceeding $100 million over the four consecutive quarters ending with the third quarter of 2020. This payment was recorded as milestone revenue in the third quarter. We retained approximately $14 million of the milestone payment net of our payment obligations to another party.

67

Convertible Notes

In December 2019, we announced the successful completion of a private exchange of $276 million of our convertible senior notes due in 2021 in exchange for a combination of approximately $207 million aggregate principal amount of newly-issued convertible senior secured notes due 2024 and $55.2 million in cash. The convertible senior secured notes due 2021 have an adjusted conversion price of approximately $21.00 per share. As a result of the exchange, approximately $69 million of convertible senior notes due in 2021, with an adjusted conversion price of approximately $255.35, remain outstanding. Addressing the remaining portion of the convertible notes due 2021 is a top priority in addition to our focus on the Inbrija launch. More information about the terms and conditions of the 2021 and 2024 convertible notes is set forth in Note 9 to our Consolidated Financial Statements included in this report as well as in Financing Arrangements in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of this report.

Sale of Chelsea, Massachusetts Manufacturing Operations

In February 2021, we completed the sale of our Chelsea, Massachusetts manufacturing operations to Catalent Pharma Solutions. Pursuant to the transaction, Catalent paid us $80 million in cash, resulting in net proceeds to us of approximately $74 million after transaction fees and expenses and settlement of customary post-closing adjustments. In connection with the sale of the manufacturing operations, we entered into a long-term, global manufacturing services agreement with a Catalent affiliate for the supply of Inbrija. As part of the transaction, Catalent hired substantially all of our prior employees at the Chelsea facility as well as certain of our other employees at our Waltham, Massachusetts facility. We intend to use the net proceeds received from the transaction for general corporate purposes, subject to compliance with the terms of the 2024 notes, which may include funding capital expenditures and the repayment of indebtedness. Also, we expect to save approximately $10 million in annual operating expenses related to the operation of the manufacturing facility. More information about the Catalent transaction is set forth in Part I of this report under Catalent Transaction. See Note 7 to our Consolidated Financial Statements included in this report for additional information on the assets classified as held for sale as a result of the transaction.

Financial Management

In January 2021, we announced a corporate restructuring to reduce costs and focus our resources on Inbrija, which is our key strategic priority for 2021. As part of the restructuring, we reduced headcount by approximately 16% through a reduction in force (excluding the employees that transferred to Catalent at the closing of the sale of our Chelsea manufacturing operations). All of the reduction in personnel will take place in the first quarter of 2021. As a result, we expect to realize estimated annualized cost savings related to headcount reduction of approximately $6 million beginning in the second quarter of 2021. We estimate that we will incur approximately $3.2 million of pre-tax charges, substantially all of which will be cash expenditures, for severance and other employee separation-related costs in the first quarter of 2021.

In January 2021, we entered into an At The Market (ATM) Offering Agreement with H.C. Wainwright & Co., LLC as sales agent. Pursuant to the ATM agreement, we may offer and sell shares of our common stock having an aggregate value of up to $15.25 million in an at-the-market offering, subject to a 3% sales commission payable to H.C. Wainwright. If we elect to use the ATM agreement, H.C. Wainwright would be obligated to use commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell shares in accordance with our instructions (including as to price, time or size limit or other parameters or conditions that we may impose).

On July 13, 2020, we received a U.S. income tax refund from the Internal Revenue Service of approximately $12.4 million plus interest of $0.3 million, pursuant to the Coronavirus Aid, Relief, and Economic Security Act (CARES Act). Under the CARES Act, among other things, net operating losses arising in a taxable year beginning after December 31, 2017, and before January 1, 2021, can be carried back to the preceding five years to apply against taxable income reported in such years. Pursuant to this provision of the CARES Act, the Company was eligible to carry back 2019 net operating losses to tax years 2017 and 2018, resulting in the refund.

As of December 31, 2020, we had cash, cash equivalents, short-term investments and restricted cash of approximately $102.9 million. Restricted cash includes $31.1 million in escrow related to the 6% semi-annual interest portion of the convertible senior secured notes due 2024, payable in cash or stock. As further described in Note 9 to our Consolidated Financial Statements included in this report as well as in Financing Arrangements in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of this report, if we are permitted under the notes indenture and we elect to pay interest due in stock, the cash equivalent will be released from escrow. In December 2020, we issued

68

1,484,871 shares to the holders of the 2024 notes in satisfaction of approximately $6.2 million in interest due on December 1, 2020, and a corresponding amount was released from the escrow in late December 2020.

Nasdaq Listing Rules and Reverse Stock Split

On January 19, 2021, we received a letter from The Nasdaq Stock Market, LLC notifying us that we had regained compliance with Listing Rule 5450(a)(1), which requires that listed securities maintain a minimum closing bid price of at least $1.00 per share (the “Minimum Bid Requirement”). We regained compliance with the Minimum Bid Requirement based on the closing bid price of our common stock on the Nasdaq Global Select Market between January 4, 2021 and January 15, 2021. We had previously been notified, on July 23, 2020, of our non-compliance with the Minimum Bid Requirement.

On December 31, 2020, we filed an amendment to our Certificate of Incorporation which effected, as of 4:01 p.m. Eastern Time on December 31, 2020, a 1-for-6 reverse stock split of the shares of our outstanding common stock and proportionate reduction in the number of authorized shares of our common stock from 370,000,000 to 61,666,666. Our Board of Directors approved the reverse stock split as part of plan to regain compliance with the Minimum Bid Requirement. The reverse stock split had previously been authorized by our stockholders at a special meeting convened on July 31, 2020.

Our common stock began trading on a split-adjusted basis on The Nasdaq Global Select Market commencing upon market open on January 4, 2021. The common stock continued to trade under the symbol “ACOR” after the reverse stock split became effective. The reverse stock split applied equally to all outstanding shares of the common stock and did not modify the rights or preferences of the common stock. The reverse stock split also resulted in a corresponding adjustment to outstanding equity awards as well as shares reserved for future issuance under our incentive compensation plans.

All figures in this report relating to shares of our common stock (such as share amounts, per share amounts, and conversion rates and prices), including in the financial statements and accompanying notes to the financial statements, have been retroactively restated to reflect the 1-for-6 reverse stock split of our common stock.

COVID-19 Pandemic

Our business and financial condition have been impacted by, and are subject to risks resulting from, the COVID-19 (novel coronavirus) pandemic. The COVID-19 pandemic has caused significant disruptions in the healthcare industry. The duration of the pandemic is difficult to predict, and it is likely to have ongoing impacts as it continues. The travel restrictions, “shelter in place” orders, quarantine policies, and general concerns about the spread of COVID-19 have disrupted the delivery of healthcare to patients, for example making it more difficult for some patients to visit with their physician and obtain pharmaceutical prescriptions. Also, healthcare office staffing shortages may delay the administrative work, and particularly insurance-related documentation, needed to obtain reimbursement for prescriptions. We believe these factors contributed to volatility in new Inbrija prescriptions during 2020.

The COVID-related policies, restrictions and concerns may disrupt our operations and those of our customers and suppliers. Also, our operations could be interrupted if we or our customers or suppliers lose the services of key employees or consultants who become ill from COVID-19. These types of disruptions could potentially affect any of our critical business functions, and thus harm our business, including for example our manufacturing, sales and marketing operations as well compliance and certain general and administrative functions. The ultimate impact of the COVID-19 pandemic, or any other health epidemic, is highly uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, healthcare systems or the global economy as a whole. As the pandemic continues, it may result in a sustained economic downturn that could affect demand for our products and our ability to access capital on reasonable terms, or at all.

Inbrija (levodopa inhalation powder)/Parkinson’s Disease

Inbrija (levodopa inhalation powder) is the first and only inhaled levodopa, or L-dopa, for intermittent treatment of OFF episodes, also known as OFF periods, in people with Parkinson’s disease treated with carbidopa/levodopa regimen. Our New Drug Application, or NDA, for Inbrija was approved by the U.S. Food and Drug Administration, or FDA, on December 21, 2018. The approval is for a single dose of 84 mg (administered as two capsules), which may be taken up to five times per day. Inbrija became commercially available in the U.S. on February 28, 2019. Currently, Inbrija is available in the U.S. without the need for a medical exception for approximately 96% of commercial health insurance plan and approximately

69

25% of Medicare plan lives. Net revenue for Inbrija was $24.2 million for the year ended December 31, 2020. We project peak U.S. annual net revenue of Inbrija to be in the range of $300 to $500 million.

In September 2019, we announced that the European Commission, or EC, approved our Marketing Authorization Application, or MAA, for Inbrija. The approved dose is 66 mg (administered as two capsules) up to five times per day (per European Union, or EU, convention, this reflects emitted dose and is equivalent to the 84 mg labelled dose in the U.S.). Under the MAA, Inbrija is indicated in the EU for the intermittent treatment of episodic motor fluctuations (OFF episodes) in adult patients with Parkinson’s disease treated with a levodopa/dopa-decarboxylase inhibitor. The MAA approved Inbrija for use in what were then the 27 countries of the EU, as well as Iceland, Norway and Liechtenstein. Following the ratification of the Withdrawal Agreement between the United Kingdom and the EU, the UK left the EU on January 31, 2020. Following the ratification of the Withdrawal Agreement between the United Kingdom and the EU, the UK left the EU on January 31, 2020. Effective January 1, 2021, Acorda was granted a grandfathered Marketing Authorization (MA) by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK which is subject to certain administrative filings that are due by December 31, 2021. We are in discussions with potential partners regarding the distribution of Inbrija outside of the U.S., with potential partners in Europe and Japan.

Inbrija is marketed in the U.S. through our own specialty sales force and commercial infrastructure, which we are supplementing with sales representatives provided by a contract commercial organization. Inbrija is distributed in the U.S. primarily through:  Alliance Rx Walgreens Prime, or Walgreens, a specialty pharmacy that delivers the medication to patients by mail; and ASD Specialty Healthcare, Inc. (an AmeriSource Bergen affiliate). During 2020, we transitioned from a network of several specialty pharmacies to Walgreens as the sole specialty pharmacy for U.S. sales of Inbrija, which we believe has potential benefits to patients and our business. Our neuro-specialty sales and marketing team includes our own sales representatives as well as established teams of Medical Science Liaisons, Regional Reimbursement Directors, and Market Access Account Directors who provide information to payers and physicians on our marketed products; and Market Development Managers who work collaboratively with field teams and corporate personnel to assist in the execution of the Company’s strategic initiatives. Our sales representatives (with the contracted representatives) are targeting approximately 5,000 healthcare providers, currently focusing on a priority list of approximately 2,000 physicians who are high volume prescribers of levodopa/carbidopa. Our Inbrija launch activities are focused on physician awareness and market access as well as patient awareness, education and training.

We have established Prescription Support Services for Inbrija, which we sometimes refer to as the Inbrija hub. Prescription Support Services is designed to help patients navigate their insurance coverage and offer reimbursement support services, when appropriate. Services fall into one of these categories: insurance verification, to research patient insurance benefits and confirm insurance coverage; prior authorization support, to identify prior authorization requirements; and appeals support. For patients that may need assistance paying for their medication, Prescription Support Services offers several support options, including: a program that provides no cost medication to patients who meet specific program eligibility requirements; co-pay support, which may help commercially insured (non-government funded) patients lower their out-of-pocket costs; and a bridge program, for federally-insured patients who experience a delay in coverage determination. We have implemented a no-cost sample program, available at physician offices, to enable patients and their physicians to assess the value of Inbrija before the patient incurs out-of-pocket co-pay or co-insurance costs. In addition, we have implemented a free trial program, available through the Inbrija hub, for commercially insured patients who cannot access the free samples because of offices and institutions that have policies that prohibit samples. Parkinson’s disease is a progressive neurodegenerative disorder resulting from the gradual loss of certain neurons in the brain. These neurons are responsible for producing dopamine and that loss causes a range of symptoms including impaired movement, muscle stiffness and tremors. The standard baseline treatment of Parkinson’s disease is oral carbidopa/levodopa, but oral medication can be associated with wide variability in the timing and amount of absorption and there are significant challenges in creating a regimen that consistently maintains therapeutic effects. As Parkinson’s progresses, people are likely to experience OFF periods, which are characterized by the return of Parkinson’s symptoms that result from low levels of dopamine between doses of oral carbidopa/levodopa. OFF periods are often highly disruptive to people with Parkinson’s. Approximately one million people in the U.S. and 1.2 million Europeans are diagnosed with Parkinson’s; it is estimated that approximately 40% of people with Parkinson’s in the U.S. experience OFF periods.

Inbrija is for as needed use and utilizes our ARCUS platform for inhaled therapeutics. ARCUS is a dry-powder pulmonary drug delivery technology that we believe has potential to be used in the development of a variety of inhaled medicines. The ARCUS platform allows systemic delivery of medication through inhalation, by transforming molecules into a light, porous dry powder. This allows delivery of substantially higher doses of medication than can be delivered via conventional dry powder technologies. We acquired the ARCUS technology platform as part of our 2014 acquisition of Civitas Therapeutics. We have worldwide rights to our ARCUS drug delivery technology, which is protected by extensive

70

know-how and trade secrets and various U.S. and foreign patents, including patents that protect the Inbrija dry powder capsules beyond 2030. We have several patents listed in the Orange Book for Inbrija, including patents expiring between 2022 and 2032, and Inbrija is entitled to three years of new product exclusivity, through December 2021, as posted in the Orange book.

Ampyra

Ampyra was approved by the FDA in January 2010 to improve walking in adults with multiple sclerosis. To our knowledge, Ampyra is the first drug approved for this indication. Efficacy was shown in people with all four major types of MS (relapsing remitting, secondary progressive, progressive relapsing and primary progressive). Ampyra became subject to competition from generic versions of Ampyra starting in late 2018 as a result of an adverse U.S. federal district court ruling that invalidated certain Ampyra Orange Book-listed patents. We have experienced a significant decline in Ampyra sales due to competition from several generic versions of Ampyra. Additional manufacturers may market generic versions of Ampyra, and we expect our Ampyra sales will continue to decline over time. Net revenue for Ampyra was $98.1 million for the year ended December 31, 2020.

License and Collaboration Agreement with Biogen

Ampyra is marketed as Fampyra outside the U.S. by Biogen International GmbH, or Biogen, under a license and collaboration agreement that we entered into in June 2009. Fampyra has been approved in a number of countries across Europe, Asia and the Americas. Under our agreement with Biogen, we are entitled to receive double-digit tiered royalties on net sales of Fampyra and we are also entitled to receive additional payments based on achievement of certain regulatory and sales milestones. In October 2020, we received a $15 million milestone payment from Biogen based on ex-U.S. net sales exceeding $100 million over the four consecutive quarters ending with the third quarter of 2020. This payment was recorded as milestone revenue in the third quarter. We retained approximately $14 million of the milestone payment net of our payment obligations to another party. In November 2017, we announced a $40 million Fampyra royalty monetization transaction with HealthCare Royalty Partners, or HCRP. In return for the payment to us, HCRP obtained the right to receive these Fampyra royalties up to an agreed-upon threshold. Until this threshold is met, if ever, we will not receive Fampyra royalties although we retained the right to receive any potential future milestone payments, including the milestone payment described above. The HCRP transaction is accounted for as a liability, as described in Note 10 to our Consolidated Financial Statements included in this report.

Ampyra Patent Update

There are no patents listed in the Orange Book for Ampyra. Ampyra became subject to competition from generic versions of Ampyra starting in late 2018 as a result of an adverse U.S. federal district court ruling that invalidated certain Ampyra Orange Book-listed patents.

There are two European patents, EP 1732548 and EP 2377536, with claims directed to use of a sustained release dalfampridine composition (known under the trade name Fampyra in the European Union) to increase walking speed in a patient with multiple sclerosis. Both European patents are set to expire in 2025, absent any additional exclusivity granted based on regulatory review timelines. Nullity actions have been filed in Germany against both of the German national patents derived from EP 1732548 and EP 2377536 by ratiopharm GmbH, a generic manufacturer affiliated with Teva. Fampyra also has 10 years of market exclusivity in the European Union that is set to expire in 2021.

We will vigorously defend our intellectual property rights.

ARCUS Product Development

We have been exploring opportunities for other proprietary products in which inhaled delivery of medicine using our ARCUS drug delivery technology can provide a significant therapeutic benefit to patients. We believe there are potential opportunities with central nervous system, or CNS, as well as non-CNS, disorders.

Our ARCUS development has been focused on a program for acute treatment of migraine. Existing oral therapies for migraine can be associated with slow onset of action and gastrointestinal challenges. Patients cite the need for rapid relief from migraine symptoms as their most desired medication attribute. Additionally, individuals with migraine may suffer from

71

nausea and delayed gastric emptying which further impact the consistency and efficacy of the oral route of administration. We have been evaluating therapeutic candidates for their suitability to move forward with this program. Due to our three restructurings since 2017 and associated cost-cutting measures, we have deferred consideration of further investment into potential new ARCUS applications in migraine pending additional progress with the Inbrija commercial launch in the U.S.

Should we decide in the future to make investments in any ARCUS development program, we would be reliant on Catalent for the manufacture of product for that program. Our global supply agreement with Catalent does not provide for the terms and conditions under which Catalent would supply any product or product candidate other than Inbrija. We would be unable to advance the development of any ARCUS inhaled therapeutic candidate unless Catalent is willing to manufacture the candidate for us on commercially reasonable terms. Also, due to reductions in force, employee attrition and the 2021 sale of our Chelsea manufacturing operations, we believe we lack certain personnel needed for, and would need to hire replacements before continuing with, this research and development work.

In July 2015, the Bill & Melinda Gates Foundation awarded us a grant to support the development of a formulation and delivery system for a dry powder version of lung surfactant, a treatment for neonatal respiratory distress syndrome, or nRDS. In collaboration with the Massachusetts Institute of Technology, we developed a formulation and delivery device based on our proprietary ARCUS drug delivery technology. nRDS is a condition affecting prematurely born infants in which their lungs are underdeveloped and thus lack a sufficient amount of lung surfactant. It can be fatal, or lead to severe, chronic health issues caused by a lack of oxygen getting to the baby’s brain and other organs. Delivering liquid surfactant to the lungs via intubation is the standard of care. We believe that our formulation and delivery system may present a more practical alternative for use in developing areas of the world, where intubation poses numerous problems. Based on achievement of pre-clinical proof of concept, the foundation expanded the funding to include pre-IND development, including an additional grant of approximately $2.08 million in 2020 to continue this work. This program is not aimed at developing a commercial product, but our work on this program could potentially generate information that is useful for adapting the ARCUS drug delivery technology to commercial pediatric uses. We expect all current grant-funded work to be completed in the first half of 2021. We are evaluating next steps for our continuing involvement in this program as it transitions past the grant-funding stage and in light of the sale of our Chelsea manufacturing operations and other factors.

Other Research and Development Programs

Our other research and development programs include rHIgM22 and cimaglermin alfa. rHIgM22 is a remyelinating antibody that is a potential therapeutic for multiple sclerosis. Data from a Phase 1 safety and tolerability trial showed that a single dose of rHIgM22 was not associated with any safety signals. The study was not powered to show efficacy and exploratory measures showed no difference between the treatment groups. Cimaglermin alfa is a member of the neuregulin growth factor family, and has been shown to promote recovery after neurological injury, as well as enhance heart function in animal models of heart failure. We initiated a Phase 1b clinical trial assessing three doses of cimaglermin alfa in people with heart failure, but discontinued enrollment and then received an FDA clinical hold based on the occurrence of a case of hepatotoxicity (liver injury). The FDA clinical hold was lifted after we presented additional data on the hepatotoxicity, but we have not since restarted any clinical study of cimaglermin alfa. We are considering next steps for these programs, which could include potential partnering or out-licensing, but due to our three restructurings since 2017 and associated cost-cutting measures, we have deferred consideration of any further investment pending additional progress with the Inbrija commercial launch in the U.S.

Financial Guidance for 2021

We are providing the following guidance with respect to our 2021 financial performance:

The projected range of operating expenses in 2021 specified above was not prepared in accordance with accounting principles generally accepted in the United States (GAAP) because this guidance excludes restructuring costs and share-based compensation charges. Due to the forward looking nature of this information, the amount of compensation charges and benefits needed to reconcile this measure to the most directly comparable GAAP financial measure is dependent on future changes in the market price of our common stock and is not available at this time. Non-GAAP financial measures are not an

72

alternative for financial measures prepared in accordance with GAAP. However, we believe the presentation of this non-GAAP financial measure, when viewed in conjunction with actual GAAP results, provides investors with a more meaningful understanding of our ongoing and projected operating performance because it excludes (i) expenses that pertain to a non-routine restructuring event, and (ii) non-cash charges that are substantially dependent on changes in the market price of our common stock. We believe this non-GAAP financial measure helps indicate underlying trends in our business and is important in comparing current results with prior period results and understanding expected operating performance. Also, our management uses this non-GAAP financial measure to establish budgets and operational goals, and to manage our business and to evaluate its performance.

Results of Operations

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019

Net Revenue

Net Product Revenues

Inbrija

We recognize product sales of Inbrija following receipt of product by companies in our distribution network, which for Inbrija primarily includes specialty pharmacies, which deliver the medication to patients by mail, and ASD Specialty Healthcare, Inc. (an AmeriSource Bergen affiliate). We recognized net revenue from the sale of Inbrija of $24.2 million and $15.3 million for the years ended December 31, 2020 and 2019, respectively. The increase in Inbrija net revenue was due to an increase in net volume of $8.9 million.

Discounts and allowances which are included as an offset in net revenue consist of allowances for customer credits, including estimated chargebacks, rebates, returns and discounts. Discounts and allowances are recorded following shipment of our products to our customers. Adjustments are recorded for estimated chargebacks, rebates, and discounts. Discounts and allowances also consist of discounts provided to Medicare beneficiaries whose prescription drug costs cause them to be subject to the Medicare Part D coverage gap (i.e., the “donut hole”). Payment of coverage gap discounts is required under the Affordable Care Act, the health care reform legislation enacted in 2010. Discounts and allowances may increase as a percentage of sales as we enter into new managed care contracts in the future.

We believe that first and fourth quarter revenue for our products is subject to certain recurring seasonal factors relating to the commencement of a new calendar year. For example, some patients refill their prescriptions earlier ahead of the new year, in the fourth quarter, in anticipation of the year-end reset of health plan deductibles and the Medicare donut hole, or a year-end switch of their insurance plans or pharmacy benefit providers. Also, we believe specialty pharmacies may increase their stock, within contractual limits, to account for the holidays and new year. These factors may seasonally have a positive impact on fourth quarter revenues and a negative impact on first quarter revenues. Also, discounts and allowances typically are highest in the first quarter, and lowest in the fourth quarter, and when this occurs this increases fourth quarter revenues, and decreases first quarter revenues, on a relative basis. In the case of the fourth quarter of 2020, we believe our transition from a network of several specialty pharmacies to Alliance Rx Walgreens Prime, or Walgreens, as the sole specialty pharmacy for U.S. sales of Inbrija was another factor that positively impacted Inbrija net sales on a one-time basis, as Walgreens initiated stocking for newly-transferred patients during the quarter.

Ampyra

We recognize product sales of Ampyra following receipt of product by companies in our distribution network, which for Ampyra primarily includes specialty pharmacies, which deliver the medication to patients by mail. We recognized net revenue from the sale of Ampyra to these customers of $98.9 million and $164.9 million for the years ended December 31, 2020 and 2019, respectively. These amounts are inclusive of Mylan AG revenue of $0.8 million and $1.7 million for the years ended December 31, 2020 and 2019, respectively. The decrease in Ampyra net revenue was composed of a decrease in net volume of $79.5 million partially offset by price increase and discount and allowance adjustments of $14.4 million. Net

73

revenue from sales of Ampyra decreased for the year ended December 31, 2020 compared to the year ended December 31, 2019 due to the entry of generic versions of Ampyra as a result of the invalidation of our Ampyra patents in 2017.

Discounts and allowances which are included as an offset in net revenue consist of allowances for customer credits, including estimated chargebacks, rebates, returns and discounts. Discounts and allowances are recorded following shipment of our products to our customers. Adjustments are recorded for estimated chargebacks, rebates, and discounts. Discounts and allowances also consist of discounts provided to Medicare beneficiaries whose prescription drug costs cause them to be subject to the Medicare Part D coverage gap (i.e., the “donut hole”). Payment of coverage gap discounts is required under the Affordable Care Act, the health care reform legislation enacted in 2010. Discounts and allowances may increase as a percentage of sales as we enter into new managed care contracts in the future.

We believe that first and fourth quarter revenue for our products is subject to certain recurring seasonal factors relating to the commencement of a new calendar year. For example, some patients refill their prescriptions earlier ahead of the new year, in the fourth quarter, in anticipation of the year-end reset of health plan deductibles and the Medicare donut hole, or a year-end switch of their insurance plans or pharmacy benefit providers. Also, we believe specialty pharmacies may increase their stock, within contractual limits, to account for the holidays and new year. These factors may seasonally have a positive impact on fourth quarter revenues and a negative impact on first quarter revenues. Also, discounts and allowances typically are highest in the first quarter, and lowest in the fourth quarter, and when this occurs this increases fourth quarter revenues, and decreases first quarter revenues, on a relative basis.

Other Product Revenues

We recognized net revenue from the sale of other products of $1.7 million for the year ended December 31, 2020 as compared to $0.6 million for the year ended December 31, 2019.

Milestone Revenue

We recognized $15 million and $0 million in milestone revenue for the year ended December 31, 2020 and 2019, respectively. The increase is due to the $15 million milestone payment earned in the three-month period ended September 30, 2020 and received from Biogen in October 2020 based on ex-U.S. Fampyra net sales exceeding $100 million over a period of four consecutive quarters ending with the third quarter of 2020. We will retain approximately $14 million of the milestone payment net of our payment obligations to another party.

Royalty Revenue

We recognized $13.1 million in royalty revenue for the year ended December 31, 2020 as compared to $11.7 million for the year ended December 31, 2019, related to ex-U.S. sales of Fampyra by Biogen.

Cost of Sales

We recorded cost of sales of $33.5 million for the year ended December 31, 2020 as compared to $34.8 million for the year ended December 31, 2019. Cost of sales for the year ended December 31, 2020 consisted primarily of $14.7 million in inventory costs related to recognized revenues, $4.1 million in royalty fees based on net product shipments, idle capacity costs of $6.3 million, $8.2 million in period costs related to expired inventory, freight, stability testing, and packaging and $0.2 million for costs related to sales of the authorized generic version of Ampyra. Production costs related to idle capacity are not included in the cost of inventory but are charged directly to cost of sales in the period incurred.

Cost of sales for the year ended December 31, 2019 consisted primarily of $32.2 million in inventory costs related to recognized revenues, $0.9 million in royalty fees based on net product shipments, idle capacity costs of $0.7 million, $0.5 million in period costs related to freight, stability testing, and packaging and $0.5 million for costs related to sales of the authorized generic version of Ampyra. Cost of sales of $1.8 million for inventory manufactured pre-launch for Inbrija was not recorded for the year ended December 31, 2019, since the inventory manufactured prior to the FDA approval was expensed as research and development expense as incurred and was combined with other research and development expenses in 2018.

74

Amortization of Intangibles

We commenced amortization of the intangible asset upon launch in February 2019 and recorded amortization of $30.8 million for the year ended December 31, 2020 as compared to $25.6 million related to Inbrija for the year ended December 31, 2019.

Research and Development

Research and development expenses for the year ended December 31, 2020 were $23.0 million as compared to $60.1 million for the year ended December 31, 2019, a decrease of $37.1 million, or 62%. The decrease was primarily due to reductions in spending of $26.4 million due to the commercialization of Inbrija, reductions of $11.0 million due to restructuring and decrease in several programs to shift focus on Inbrija launch, partially offset by increases of $0.3 million in research and development expenses related to Biotie.

Selling, General and Administrative

Sales and marketing expenses for the year ended December 31, 2020 were $81.2 million compared to $109.5 million for the year ended December 31, 2019, a decrease of approximately $28.3 million, or 26%. The decrease was attributable primarily to a decrease in marketing related spending of $7.9 million due to launch activities for Inbrija, a decrease in overall salaries and benefits of $11.2 million and a decrease in spending related to marketing for Ampyra of $9.2 million.

General and administrative expenses for the year ended December 31, 2020 were $71.3 million compared to $83.3 million for the year ended December 31, 2019, a decrease of approximately $12.0 million, or 14%. This decrease was primarily due to a decrease in spending related to launch activities of $0.8 million, a decrease of $6.6 million in staff compensation, benefits and medical affairs related expenses, a decrease of $1.0 million in business development costs and human resources costs, and a decrease of $3.0 million in restructuring expenses.

Goodwill and Intangible Asset Impairments

We recognized an intangible asset impairment charge of $4.1 million for the year ended December 31, 2020. During the first quarter of 2020, the Company determined that there were relevant changes to the key assumptions that would negatively affect the value of the IPR&D asset for BTT-1023. Management determined that the results of the clinical trial did not meet the primary or secondary end-points, and the clinical trial was not large enough or expansive enough to be persuasive to generate interest by third-parties for a possible licensing arrangement. Management determined that this assessment was the triggering event that indicated that the asset was fully impaired as there was no potential value with an out-licensing arrangement. Based on the qualitative assessment, management determined that the carrying value of the asset exceeded its estimated fair value and therefore, the asset was fully impaired. Management determined that additional quantitative procedures were not relevant in this circumstance given the overwhelming qualitative evidence that indicated the asset was fully impaired.

We recognized a goodwill impairment charge of $277.6 million for the year ended December 31, 2019. During the third quarter of 2019, we experienced a significant decline in our stock price that reduced the market capitalization below the carrying value of the Company. We performed a quantitative assessment and after completing the assessment during the third quarter of 2019, we concluded that the carrying value of the Company exceeded its estimated fair value and therefore, the goodwill was fully impaired.

Loss on Assets Held for Sale

As a result of the sale of the Chelsea manufacturing operations to Catalent, the Company determined that the criterion to classify the Chelsea manufacturing operations as assets held for sale within the Company’s consolidated balance sheet effective December 31, 2020 were met. Accordingly, the assets were classified as current assets held for sale at December 31, 2020 as the Company, at that time, expected to divest the Chelsea manufacturing operations within the next twelve months. The Company entered into a definitive agreement to sell the Chelsea manufacturing operations on January 12, 2021 and closed the transaction on February 10, 2021. The classification to assets held for sale impacted the net book value of the assets expected to be transferred upon sale. The estimated fair value of the Chelsea manufacturing operations was determined using the purchase price in the purchase agreement along with estimated broker, accounting, legal, and other selling

75

expenses, which resulted in a fair value less costs to sell of approximately $71.8 million. The carrying value of the assets being classified as held for sale was approximately $129.7 million, which includes property and equipment of $129.6 million and prepaid expenses of $0.1 million. As a result, the Company recorded a loss on assets held for sale of $57.9 million against the Chelsea manufacturing operations for the year ended December 31, 2020.

Change in Fair Value of Derivative Liability

A derivative liability was recorded in December 2019 as a result of the issuance of the 6.00% Convertible Senior Secured Notes due 2024. The derivative liability is measured at fair value on a quarterly basis and changes in the fair value are recorded in the consolidated statement of operations. We recorded income of $40.0 million due to the change in the fair value of the derivative liability for the year ended December 31, 2020. The changes in the fair value of the derivative liability were primarily due to changes in the Company’s stock price over the period.

Changes in Fair Value of Acquired Contingent Consideration

As a result of the original spin out of Civitas from Alkermes, part of the consideration to Alkermes was a future royalty to be paid to Alkermes on Inbrija. Acorda acquired this contingent consideration as part of the Civitas acquisition. The fair value of that future royalty is assessed quarterly. We recorded income pertaining to changes in the fair value of our acquired contingent consideration of $30.9 million for the year ended December 31, 2020 compared to $86.9 million for the year ended December 31, 2019, a decrease of $56.0 million or 64%. The changes in the fair-value of the acquired contingent consideration were primarily due to the overall downward revision to the projected revenue and the recalculation of cash flows for the passage of time.

Other Income (Expense), Net

Other expense, net was $29.6 million for the year ended December 31, 2020 compared to other income, net of $37.4 million for the year ended December 31, 2019, a decrease in income of $67.0 million, or 179%. The decrease was due primarily to the gain recorded on debt extinguishment of $55.1 million in 2019, a decrease in interest income of approximately $3.4 million, an increase in interest and amortization of debt discount expense of approximately $8.7 million, partially offset by an increase in other income $0.2 million.

Benefit from Income Taxes

We recorded a $8.1 million benefit from income taxes for the year ended December 31, 2020 as compared to a $1.3 million benefit from income taxes for the year ended December 31, 2019. The effective income tax rates for the year ended December 31, 2020 and 2019 were 7.5% and 0.5%, respectively.

The variances in the effective tax rates for the year ended December 31, 2020 and 2019 were due primarily to the valuation allowance recorded on deferred tax assets for which no tax benefit can be recognized, goodwill impairment for which no tax benefit can be recognized, and the benefit recorded on the net operating loss carryback under the CARES act recorded at 21% to recover taxes paid at the previous statutory rate of 35%.

The Company’s overall effective tax rate in 2020 differed from the U.S. federal statutory rate of 21% primarily due to the benefit recorded on the net operating loss carryback under the CARES act recorded at 21% to recover taxes paid at the previous statutory rate of 35%, the forfeitures of equity of which no tax deduction is recorded and the valuation allowance recorded on deferred tax assets for which no tax benefit can be recognized.

The Company continues to evaluate the realizability of its deferred tax assets on a quarterly basis and will adjust such amounts in light of changing facts and circumstances including, but not limited to, future projections of taxable income, tax legislation, rulings by relevant tax authorities, the progress of ongoing tax audits and the regulatory approval of products currently under development. Any changes to the valuation allowance or deferred tax assets and liabilities in the future would impact the Company's income taxes.

The Company’s state examination by the state of Massachusetts for tax periods 2016 and 2017 was completed during the third quarter of 2020. The Company was assessed an immaterial tax approximately $0.02 million.

76

The Company has ongoing state examinations in New Jersey and Minnesota which cover a range of tax periods, 2015-2018. There have been no proposed adjustments at this stage of these examinations.

Liquidity and Capital Resources

Since our inception, we have financed our operations primarily from: private placements and public offerings of our capital stock; borrowing money through loans and the issuance of debt instruments; payments received under our collaboration and licensing agreements; revenue from sales of Ampyra, Fampyra, and Inbrija, as well as our former products, Zanaflex and Qutenza; royalty monetizations and our revenue interest financing arrangement; and, to a lesser extent, funding from government grants. Also, in February 2021, we obtained additional capital from the sale of our Chelsea manufacturing operations.

At December 31, 2020, we had $71.4 million of cash, cash equivalents and short-term investments, compared to $125.8 million at December 31, 2019. Our December 31, 2020 cash, cash equivalents and short-term investments balance does not include restricted cash, currently held in escrow under the terms of our convertible senior secured notes due 2024, further described below under Financing Arrangements, which may potentially be released from escrow if we pay interest on those notes using shares of our common stock. The December 31, 2020 balance also does not include the net proceeds received from the sale of our Chelsea manufacturing operations. We incurred net losses of $99.6 million and $273.0 million for the years ended December 31, 2020 and 2019, respectively.

Our future capital requirements will depend on a number of factors, including:

Our ability to meet our future operating requirements, repay our liabilities, and meet our other obligations are dependent upon a number of factors, including our ability to generate cash from product sales, reduce planned expenditures, and obtain additional financing. If we are unable to generate sufficient cash flow from the sale of our products, we may be required to adopt one or more alternatives, subject to the restrictions contained in the indenture governing our 2024 Notes, such as further reducing expenses, selling assets, restructuring debt, or obtaining additional equity capital on terms that may be onerous and which are likely to be highly dilutive. Also, our ability to raise additional capital and repay or restructure our indebtedness will depend on the capital markets and our financial condition at such time, among other factors. In addition, financing may not be available when needed, at all, on terms acceptable to us or in accordance with the restrictions described above.

Financing Arrangements

Convertible Senior Secured Notes Due 2024

On December 24, 2019, the Company completed the private exchange of $276.0 million aggregate principal amount of its outstanding 1.75% Convertible Senior Notes due 2021 (the “2021 Notes”) for a combination of newly-issued 6.00% Convertible Senior Secured Notes due 2024 (the “2024 Notes”) and cash. For each $1,000 principal amount of exchanged 2021 Notes, the Company issued $750 principal amount of the 2024 Notes and made a cash payment of $200 (the “Exchange”). In the aggregate, the Company issued approximately $207.0 million aggregate principal amount of the 2024 Notes and paid approximate $55.2 million in cash to participating holders. The Exchange was conducted with a limited number of institutional holders of the 2021 Notes pursuant to Exchange Agreements dated as of December 20, 2019 (each, an “Exchange Agreement”).

The 2024 Notes were issued pursuant to an Indenture, dated as of December 23, 2019, among the Company, its wholly owned subsidiary, Civitas Therapeutics, Inc. (along with any domestic subsidiaries acquired or formed after the date of issuance, the “Guarantors”), and Wilmington Trust, National Association, as trustee and collateral agent (the “2024 Indenture”). The 2024 Notes are senior obligations of the Company and the Guarantors, secured by a first priority security interest in substantially all of the assets of the Company and the Guarantors, subject to certain exceptions described in the Security Agreement, dated as of December 23, 2019, between the grantors party thereto and Wilmington Trust, National Association, as collateral agent (the “Security Agreement”).

The 2024 Notes will mature on December 1, 2024 unless earlier converted in accordance with their terms prior to such date. Interest on the 2024 Notes is payable semi-annually in arrears at a rate of 6.00% per annum on each June 1 and December 1, beginning on June 1, 2020. The Company may elect to pay interest in cash or shares of the Company’s common stock, subject to the satisfaction of certain conditions. If the Company elects to pay interest in shares of common stock, such common stock will have a per share value equal to 95% of the daily volume-weighted average price for the 10 trading days ending on and including the trading day immediately preceding the relevant interest payment date. In December 2020, the Company issued 1,484,871 shares of common stock in satisfaction of the interest payable to holders of the 2024 Notes on December 1, 2020. In connection with this stock-based interest payment approximately $6.2 million of accrued interest was released from restricted case and became available to the Company for other purposes.

The 2024 Notes are convertible at the option of the holder into shares of common stock of the Company at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date. The adjusted conversion rate for the 2024 Notes is 47.6190 shares of the Company’s common stock per $1,000 principal amount of 2024 Notes, representing an adjusted conversion price of approximately $21.00 per share of common stock. The conversion rate was adjusted to reflect the 1-for-6 reverse stock split effected on December 31, 2020 and is subject to additional adjustments in certain circumstances as described in the 2024 Indenture.

The Company may elect to settle conversions of the 2024 Notes in cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock. Holders who convert their 2024 Notes prior to June 1, 2023 (other than in connection with a make-whole fundamental change) will also be entitled to an interest make-whole payment equal to the sum of all regularly scheduled stated interest payments, if any, due on such 2024 Notes on each interest payment date occurring after the conversion date for such conversion and on or before June 1, 2023. In addition, the Company will have the right to cause all 2024 Notes then outstanding to be converted automatically if the volume-weighted average price per share of the Company’s common stock equals or exceeds 130% of the adjusted conversion price for a specified period of time and certain other conditions are satisfied.

Holders of the 2024 Notes will have the right, at their option, to require the Company to purchase their 2024 Notes if a fundamental change (as defined in the 2024 Indenture) occurs, in each case, at a repurchase price equal to 100% of the principal amount of the 2024 Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date. If a make-whole fundamental change occurs, as described in the 2024 Indenture, and a holder elects to convert its 2024 Notes in connection with such make-whole fundamental change, such holder may be entitled to an increase in the adjusted conversion rate as described in the 2024 Indenture.

Subject to a number of exceptions and qualifications, the 2024 Indenture restricts the ability of the Company and certain of its subsidiaries to, among other things, (i) pay dividends or make other payments or distributions on their capital stock, or purchase, redeem, defease or otherwise acquire or retire for value any capital stock, (ii) make certain investments, (iii) incur indebtedness or issue preferred stock, other than certain forms of permitted debt, which includes, among other

78

items, indebtedness incurred to refinance the 2021 Notes, (iv) create liens on their assets, (v) sell their assets, (vi) enter into certain transactions with affiliates or (vii) merge, consolidate or sell of all or substantially all of their assets. The 2024 Indenture also requires the Company to make an offer to repurchase the 2024 Notes upon the occurrence of certain asset sales.

The 2024 Indenture provides that a number of events will constitute an event of default, including, among other things, (i) a failure to pay interest for 30 days, (ii) failure to pay the 2024 Notes when due at maturity, upon any required repurchase, upon declaration of acceleration or otherwise, (iii) failure to convert the 2024 Notes in accordance with the 2024 Indenture and the failure continues for five business days, (iv) not issuing certain notices required by the 2024 Indenture within a timely manner, (v) failure to comply with the other covenants or agreements in the 2024 Indenture for 60 days following the receipt of a notice of non-compliance, (vi) a default or other failure by the Company to make required payments under other indebtedness of the Company or certain subsidiaries having an outstanding principal amount of $30.0 million or more, (vii) failure by the Company or certain subsidiaries to pay final judgments aggregating in excess of $30.0 million, (viii) certain events of bankruptcy or insolvency and (ix) the commercial launch in the United States of a product determined by the U.S. FDA to be bioequivalent to Inbrija. In the case of an event of default arising from certain events of bankruptcy or insolvency with respect to the Company, all outstanding 2024 Notes will become due and payable immediately without further action or notice. If any other event of default occurs and is continuing, the trustee or the holders of at least 25% in aggregate principal amount of the then outstanding 2024 Notes may declare all the notes to be due and payable immediately.

The 2021 Notes received by the Company in the Exchange were cancelled in accordance with their terms. Accordingly, upon completion of the Exchange, $69.0 million of the 2021 Notes remained outstanding.

The Company assessed all terms and features of the 2024 Notes in order to identify any potential embedded features that would require bifurcation. As part of this analysis, the Company assessed the economic characteristics and risks of the 2024 Notes, including the conversion, put and call features. The Company concluded the conversion features required bifurcation as a derivative. The fair value of the conversion features derivative was determined based on the difference between the fair value of the 2024 Notes with the conversion options and the fair value of the 2024 Notes without the conversion options using a binomial model. The Company determined that the fair value of the derivative upon issuance of the 2024 Notes was $59.4 million and recorded this amount as a derivative liability with an offsetting amount as a debt discount as a reduction to the carrying value of the 2024 Notes on the closing date, or December 24, 2019. There are several embedded features within the 2024 Notes which, upon issuance, did not meet the conditions for equity classification. The conversion feature is measured at fair value on a quarterly basis and the changes in the fair value of the conversion feature for the period will be recognized in the consolidated statements of operations. 

The Company received stockholder approval on August 28, 2020 to increase the number of authorized shares of the Company’s common stock from 13,333,333 shares to 61,666,666 shares. As a result of the share approval, the Company determined that multiple embedded conversion options met the conditions for equity classification. The Company performed a valuation of these conversion options as of September 17, 2020, which was the date the Company completed certain securities registration obligations. The resulting fair value of these conversion options was $18.3 million, which was reclassified to equity and presented in the statement of stockholder’s equity as of September 30, 2020, net of the $4.4 million tax impact. The equity component is not re-measured as long as it continues to meet the conditions for equity classification. The Company performed a valuation of the derivative liability related to certain embedded conversion features that are precluded from equity classification. The fair value of these conversion features was calculated to be $1.2 million as of December 31, 2020.

The outstanding 2024 Note balance as of December 31, 2020 consisted of the following:

Convertible Senior Notes Due 2021

In June 2014, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC (the “Underwriter”) relating to the issuance by the Company of $345 million aggregate principal amount of 1.75% Convertible Senior Notes due 2021 (the “2021 Notes”) in an underwritten public offering. The net proceeds from the offering were $337.5 million after deducting the Underwriter’s discount and offering expenses paid by the Company. On December 24, 2019, the Company completed the private exchange of $276.0 million aggregate principal amount of its outstanding 2021 Notes for a combination of newly-issued 6.00% Convertible Senior Secured Notes due 2024 (the “2024 Notes”) and cash. The 2021 Notes received by the Company in the exchange were cancelled in accordance with their terms. Accordingly, upon completion of the exchange, $69.0 million of the 2021 Notes remained outstanding.

The 2021 Notes are governed by the terms of an indenture, dated as of June 23, 2014 (the “Base Indenture”) and the first supplemental indenture, dated as of June 23, 2014 (the “Supplemental Indenture”, and together with the Base Indenture, the “2021 Indenture”), each between the Company and Wilmington Trust, National Association, as trustee (the “Trustee”). The 2021 Notes are convertible into cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election, based on an adjusted conversion rate of 3.9161 shares per $1,000 principal amount of 2021 Notes (representing an adjusted conversion price of approximately $255.35 per share), only in the following circumstances and to the following extent: (1) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of 2021 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; (2) during any calendar quarter commencing after the calendar quarter ending on September 30, 2014 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the adjusted conversion price on each applicable trading day; (3) if the Company calls any or all of the 2021 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; (4) upon the occurrence of specified events described in the 2021 Indenture; and (5) at any time on or after December 15, 2020 through the second scheduled trading day immediately preceding the maturity date. The conversion rate described above was adjusted to reflect the 1-for-6 reverse stock split effected on December 31, 2020 and is subject to additional adjustments in certain circumstances as described in the 2021 Indenture.

The Company may redeem for cash all or part of the 2021 Notes, at the Company’s option, after June 20, 2017 if the last reported sale price of the Company’s common stock has been at least 130% of the adjusted conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending within five trading days prior to the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the 2021 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

The Company pays 1.75% interest per annum on the principal amount of the 2021 Notes, payable semiannually in arrears in cash on June 15 and December 15 of each year. The 2021 Notes will mature on June 15, 2021.

If the Company undergoes a “fundamental change” (as defined in the 2021 Indenture), subject to certain conditions, holders may require the Company to repurchase for cash all or part of their 2021 Notes in principal amounts of $1,000 or an integral multiple thereof. The fundamental change repurchase price will be equal to 100% of the principal amount of the 2021 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. If a make-whole fundamental change occurs, as described in the 2021 Indenture, and a holder elects to convert its 2021 Notes in connection with such make-whole fundamental change, such holder may be entitled to an increase in the adjusted conversion rate as described in the 2021 Indenture.

The 2021 Indenture contains customary terms and covenants and events of default. If an event of default (other than certain events of bankruptcy, insolvency or reorganization involving the Company) occurs and is continuing, the Trustee by notice to the Company, or the holders of at least 25% in principal amount of the outstanding 2021 Notes by notice to the Company and the Trustee, may declare 100% of the principal of and accrued and unpaid interest, if any, on all the 2021 Notes to be due and payable. Upon such a declaration of acceleration, such principal and accrued and unpaid interest, if any, will be due and payable immediately. Upon the occurrence of certain events of bankruptcy, insolvency or reorganization involving the Company, 100% of the principal and accrued and unpaid interest, if any, on all of the 2021 Notes will become due and payable automatically. Notwithstanding the foregoing, the 2021 Indenture provides that, to the extent the Company elects and for up to 270 days, the sole remedy for an event of default relating to certain failures by the Company to comply

80

with certain reporting covenants in the 2021 Indenture consists exclusively of the right to receive additional interest on the 2021 Notes.

The 2021 Notes are senior unsecured obligations and rank equally with all of the Company’s existing and future senior debt and senior to any of the Company’s subordinated debt. The 2021 Notes are structurally subordinated to all existing or future indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries and are effectively subordinated to the Company’s existing or future secured indebtedness to the extent of the value of the collateral. The 2021 Indenture does not limit the amount of debt that the Company or its subsidiaries may incur.

In accounting for the issuance of the 2021 Notes, the Company separated the 2021 Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the 2021 Notes as a whole. The excess of the principal amount of the liability component over its carrying amount, referred to as the debt discount, is amortized to interest expense over the seven-year term of the 2021 Notes using the effective interest method. The equity component is not re-measured as long as it continues to meet the conditions for equity classification.

The outstanding 2021 Note balances as of December 31, 2020 and 2019 consisted of the following:

Non-Convertible Capital Loans

Non-convertible capital loans granted by Business Finland (formerly Tekes), with an adjusted acquisition-date fair value of $20.5 million (€18.2 million) and a carrying value of $26.6 million as of December 31, 2020. The loans are composed of fourteen non-convertible loans. The loans bear interest based on the greater of 3% or the base rate set by Finland’s Ministry of Finance minus one (1) percentage point. The maturity dates for these loans range from eight to ten years from the date of issuance, however, according to certain terms and conditions of the loans, the Company may repay the principal and accrued and unpaid interest of the loans only when the consolidated retained earnings of Biotie is sufficient to fully repay the loans.

Research and Development Loans

Research and Development Loans (“R&D Loans”) were granted by Business Finland with an acquisition-date fair value of $2.9 million (€2.6 million) and a carrying value of $0.7 million as of December 31, 2020. The R&D Loans bear interest based on the greater of 1% or the base rate set by Finland’s Ministry of Finance minus three (3) percentage points. The repayment of these loans began in January 2017. The loan principal will be paid in equal annual installments over a 5 year period, ending January 2021.

Fampyra Royalty Monetization

As of October 1, 2017, the Company completed a royalty purchase agreement with HealthCare Royalty Partners, or HCRP (“Royalty Agreement”). In exchange for the payment of $40 million to the Company, HCRP obtained the right to receive Fampyra royalties payable by Biogen under the Collaboration and Licensing Agreement between the Company and Biogen, up to an agreed upon threshold of royalties. When this threshold is met, if ever, the Fampyra royalty revenue will revert back to the Company and the Company will continue to receive the Fampyra royalty revenue from Biogen until the revenue stream ends.

81

The Company maintained the rights under the license and collaboration agreement with Biogen, therefore, the Royalty Agreement has been accounted for as a liability that will be amortized using the effective interest method over the life of the arrangement, in accordance with the relevant accounting guidance. The Company recorded the receipt of the $40 million payment from HCRP and established a corresponding liability in the amount of $40 million, net of transaction costs of approximately $2.2 million.

The following table shows the activity within the liability account for the years ended December 31, 2020 and 2019:

Cash, Cash Equivalents and Investment Activities

At December 31, 2020, cash and cash equivalents and short-term investments were approximately $71.4 million, as compared to $125.8 million at December 31, 2019. Our cash and cash equivalents consist of highly liquid investments with original maturities of three months or less at date of purchase and consist of investments in a Treasury money market fund. Our short-term investments consist of high-grade corporate debt securities, commercial paper and U.S. government securities with original maturities of twelve months or less at date of purchase. Also, we maintain cash balances with financial institutions in excess of insured limits. We do not anticipate any losses with respect to such cash balances. Our December 31, 2020 cash, cash equivalents and short-term investments balance does not include restricted cash, currently held in escrow under the terms of our convertible senior secured notes due 2024, further described above under Financing Arrangements, which may potentially be released from escrow if we pay interest on those notes using shares of our common stock.

Net Cash Used in Operations

Net cash used in operations was $61.0 million compared to $128.2 million for the years ended December 31, 2020 and 2019, respectively. Cash used in operations for the year ended December 31, 2020 was primarily attributable to the net loss of $99.6 million, a decrease in accounts payable, accrued expenses and other current liabilities of $9.0 million, a change in the contingent consideration obligation of $30.9 million, a change in the derivative liability of $40.0 million, gain on disposal of property and equipment of $0.2 million, royalty revenues of $11.5 million, increase in prepaid expenses and other current assets of $1.2 million, increase in inventory of $3.5 million, and decrease in other non-current liabilities of $0.2 million.

Cash used in operations was partially offset by intangible assets impairment charge of $4.1 million, loss on assets held for sale of $57.9 million, share-based compensation expense of $8.1 million, amortization of net premiums and discounts on investments of $0.6 million, depreciation and amortization expense of $41.3 million, amortization of debt discount and debt issuance costs of $16.4 million, a deferred tax provision of $4.7 million, and a decrease in accounts receivable of $1.9 million.

Net Cash Provided by Investing

Net cash provided by investing activities for the year ended December 31, 2020 was $59.4 million, which was due primarily to proceeds from maturities of investments of $63.8 million. This was partially offset by purchases of property and equipment of $4.4 million.

Net Cash Used in Financing

Net cash used in financing activities for the year ended December 31, 2020 was $1.7 million, which was due primarily to debt issuance costs related to the exchange of the convertible senior notes of $1.1 million and repayment of loans payable of $0.6 million.

82

Contractual Obligations and Commitments

Our long-term contractual obligations include commitments and estimated purchase obligations entered into in the normal course of business. See Note 13 to our Consolidated Financial Statements included in this report for a description of our long-term contractual obligations.

Under certain agreements, we are required to pay royalties for the use of technologies and products in our research and development activities and in the commercialization of products. The amount and timing of any of the foregoing payments are not known due to the uncertainty surrounding the successful research, development and commercialization of the products.

Under certain agreements, we are also required to pay license fees and milestones for the use of technologies and products in our research and development activities and in the commercialization of products. We have committed to make potential future milestone payments to third parties of up to approximately $21.6 million as part of our various agreements, including licensing and development programs. Payments under these agreements generally become due and payable only upon achievement of certain developmental, regulatory or commercial milestones. Because the achievement of these milestones had not occurred as of December 31, 2020, such contingencies have not been recorded in our financial statements. Amounts related to contingent milestone payments are not considered contractual obligations as they are contingent on the successful achievement of certain development, regulatory and commercial milestones. There is uncertainty regarding the various activities and outcomes needed to reach these milestones, and they may not be achieved.

Effects of Inflation

Our most liquid assets are cash, cash equivalents and short-term investments. Because of their liquidity, these assets are not directly affected by inflation. Because we intend to retain and continue to use our equipment, furniture and fixtures and leasehold improvements, we believe that the incremental inflation related to replacement costs of such items will not materially affect our operations. However, the rate of inflation affects our expenses, primarily employee compensation and contract services, which could increase our level of expenses.

Critical Accounting Policies and Estimates

The following discussion of critical accounting policies identifies the accounting policies that require application of management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain and may change in subsequent periods. It is not intended to be a comprehensive list of all of our significant accounting policies, which are more fully described in Note 2 of the notes to the consolidated financial statements included in this document. In many cases, the accounting treatment of a particular transaction is specifically dictated by generally accepted accounting principles, with no need for management’s judgment in their application. There are also areas in which the selection of an available alternative policy would not produce a materially different result.

Revenue Recognition

ASC 606 outlines a five-step process for recognizing revenue from contracts with customers: (i) identify the contract with the customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the separate performance obligations in the contract, and (v) recognize revenue associated with the performance obligations as they are satisfied.

The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. Once a contract is determined to be within the scope of ASC 606, the Company determines the performance obligations that are distinct. The Company recognizes as revenues the amount of the transaction price that is allocated to each respective performance obligation when the performance obligation is satisfied or as it is satisfied. Generally, the Company's performance obligations are transferred to customers at a point in time, typically upon receipt of the product by the customer.

83

ASC 606 requires entities to record a contract asset when a performance obligation has been satisfied or partially satisfied, but the amount of consideration has not yet been received because the receipt of the consideration is conditioned on something other than the passage of time. ASC 606 also requires an entity to present a revenue contract as a contract liability in instances when a customer pays consideration, or an entity has a right to an amount of consideration that is unconditional (e.g. receivable), before the entity transfers a good or service to the customer. We currently do not have any contract assets or contract liabilities.

Product Revenue, Net

Net revenue from product sales is recognized at the transaction price when the customer obtains control of the Company’s products, which occurs at a point in time, upon receipt of the product by the customer. The Company’s products are sold primarily to a network of specialty providers which are contractually obligated to hold no more than an agreed upon number of days of inventory. The Company’s payment terms are between 30 to 35 days.

The Company’s net revenues represent total revenues adjusted for discounts and allowances, including estimated cash discounts, chargebacks, rebates, returns, copay assistance, data fees and wholesaler fees for services. These adjustments represent variable consideration under ASC 606 and are recorded for the Company’s estimate of cash consideration expected to be given by the Company to a customer that is presumed to be a reduction of the transaction price of the Company’s products and, therefore, are characterized as a reduction of revenue. These adjustments are established by management as its best estimate based on available information and will be adjusted to reflect known changes in the factors that impact such allowances. Adjustments for variable consideration are determined based on the contractual terms with customers, historical trends, communications with customers and the levels of inventory remaining in the distribution channel, as well as expectations about the market for the product and anticipated introduction of competitive products.

Discounts and Allowances

Revenue from product sales are recorded at the transaction price, which includes estimates for discounts and allowances for which reserves are established and includes cash discounts, chargebacks, rebates, returns, copay assistance, data fees and wholesaler fees for services. Actual discounts and allowances are recorded following shipment of product and the appropriate reserves are credited. These reserves are classified as reductions of accounts receivable (if the amount is payable to the Customer and right of offset exists) or a current liability (if the amount is payable to a party other than a Customer). These allowances are established by management as its best estimate based on historical experience and data points available and are adjusted to reflect known changes in the factors that impact such reserves. Allowances for customer credits, chargebacks, rebates, data fees and wholesaler fees for services, returns, and discounts are established based on contractual terms with customers and analyses of historical usage of these items. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results in the future vary from the Company’s estimates, the Company will adjust these estimates, which would affect net product revenue and earnings in the period such variances become known. The nature of our allowances and accruals requiring critical estimates, and the specific considerations it uses in estimating their amounts are as follows:

Government Chargebacks and Rebates: We contract for Medicaid and other U.S. federal government programs to allow for our products to remain eligible for reimbursement under these programs. For Medicare, the Company also estimates the number of patients in the prescription drug coverage gap for whom the Company will owe an additional liability under the Medicare Part D program. Based upon our contracts and the most recent experience with respect to sales through each of these channels, we provide an allowance for chargebacks and rebates. We monitor the sales trends and adjust the chargeback and rebate percentages on a regular basis to reflect the most recent chargebacks and rebate experience. The Company’s liability for these rebates consists of invoices received for claims from prior quarters that have not been paid or for which an invoice has not yet been received, estimates of claims for the current quarter, and estimated future claims that will be made for product that has been recognized as revenue, but remains in the distribution channel inventories at the end of each reporting period. Our government chargeback and rebate accruals were $5.9 million and $5.6 million at December 31, 2020 and December 31, 2019, respectively. A 10% change in our government chargebacks and rebate allowances would have had an approximate $1.7 million and $2.2 million effect on our net revenue for the years ended December 31, 2020 and December 31, 2019, respectively.

Managed Care Contract Rebates: We contract with various managed care organizations including health insurance companies and pharmacy benefit managers. These contracts stipulate that rebates and, in some cases, administrative

84

fees, are paid to these organizations provided our product is placed on a specific tier on the organization’s drug formulary. Based upon our contracts and the most recent experience with respect to sales through managed care channels, we provide an allowance for managed care contract rebates. We monitor the sales trends and adjust the allowance on a regular basis to reflect the most recent rebate experience. The Company’s liability for these rebates consists of invoices received for claims from prior quarters that have not been paid or for which an invoice has not yet been received, estimates of claims for the current quarter, and estimated future claims that will be made for product that has been recognized as revenue, but remains in the distribution channel inventories at the end of each reporting period. Our managed care contract rebate accruals were $7.4 million and $8.5 million at December 31, 2020 and December 31, 2019, respectively. A 10% change in our managed care contract rebate allowances would have had an approximate $3.1 million and $3.2 million effect on our net revenue for the years ended December 31, 2020 and December 31, 2019, respectively.

Copay Mitigation Rebates: We offer copay mitigation to commercially insured patients who have coverage for our products (in accordance with applicable law) and are responsible for a cost share. Based upon our contracts and the most recent experience with respect to actual copay assistance provided, we provide an allowance for copay mitigation rebates. We monitor the sales trends and adjust the rebate percentages on a regular basis to reflect the most recent rebate experience. Our copay mitigation rebate accruals were $0.6 million and $0.3 million at December 31, 2020 and December 31, 2019, respectively. A 10% change in our copay mitigation rebate allowances would have had an approximate $0.5 million and $0.7 million effect on our net revenue for the years ended December 31, 2020 and December 31, 2019, respectively.

Cash Discounts: We sell directly to companies in our distribution network, which primarily includes specialty pharmacies and ASD Specialty Healthcare, Inc. (an AmeriSource Bergen affiliate). We generally provide invoice discounts for prompt payment for our products. We estimate our cash discounts based on the terms offered to our customers. Discounts are estimated based on rates that are explicitly stated in the Company’s contracts as it is expected they will take the discount and are recorded as a reduction of revenue at the time of product shipment when product revenue is recognized. We adjust estimates based on actual activity as necessary. Our cash discount allowances were $0.6 million and $0.4 million at December 31, 2020 and December 31, 2019, respectively. A 10% change in our cash discount allowances would have had an approximate $0.2 million and $0.3 million effect on our net revenue for the years ended December 31, 2020 and December 31, 2019, respectively.

Product Returns: We either offer customers no return except for products damaged in shipping or consistent with industry practice, a limited right of return based on the product’s expiration date. The Company estimates the amount of its product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized. The company currently estimates product return liabilities using historical sales information and inventory remaining in the distribution channel.

Based on the data that we receive from our customers, we have been able to make a reasonable estimate for product returns. We do not accept returns of Ampyra except for product damaged in shipping. Historically, it has been rare for us to have product damaged in shipping. We will exchange product from inventory for product damaged in shipping.

Prior to sale of Zanaflex assets in 2017, we accepted returns of Zanaflex products for six months prior to and twelve months after their expiration date. We provided a credit to customers with whom we have a direct relationship or a cash payment to those with whom we do not have a direct relationship. We do not exchange product from inventory for returned product. Our returns reserve for Zanaflex products were $0.2 million and $0.6 million at December 31, 2020 and December 31, 2019, respectively. A 10% change in our returns would have had an approximate $(0.0) million and $(0.1) million effect on our net revenue for the years ended December 31, 2020 and 2019, respectively.

Our specialty distributors for Qutenza have the right to return any unopened Qutenza product during the nine-month period beginning three months prior to the labeled expiration date and ending six months after the labeled expiration date. Once product has been opened or its expiration date does not fall within our return goods policy for Qutenza, it is no longer eligible for return. If product is returned, credit is given to the specialty distributors against amounts owed to us. We do not replace returned product with new product unless it has been damaged in shipping. Our returns accruals for Qutenza were immaterial for the years ended December 31, 2020 and December 31, 2019.

85

Data Fees and Fees for Services Payable to Specialty Pharmacies: We have contracted with certain specialty pharmacies to obtain transactional data related to our products in order to develop a better understanding of our selling channel as well as patient activity and utilization by the Medicaid program and other government agencies and managed care organizations. We pay a variable fee to the specialty pharmacies to provide us the data. We also pay the specialty pharmacies a fee in exchange for providing distribution and inventory management services, including the provision of inventory management data to the Company. We estimate our fee for service accruals and allowances based on sales to each specialty pharmacy and the applicable contracted rate. Our fee for service expenses are accrued at the time of product shipment and are typically settled with the specialty pharmacies within 60 days after the end of each respective quarter. Our data fee and fee for service accruals were $1.4 million and $1.5 million at December 31, 2020 and December 31, 2019, respectively. A 10% change in our data fee and fee for service allowances would have had an approximate $0.6 million and $0.5 million effect on our net revenue for the years ended December 31, 2020 and 2019, respectively.

We have adjusted our allowances in the past based on actual experience, and we will likely be required to make adjustments to these allowances and accruals in the future. The historical adjustments have not been significant to operations. We continually monitor our allowances and accruals and make adjustments when we believe actual experience may differ from its estimates. The allowances included in the table below reflect these adjustments.

The following table provides a summary of activity with respect to the Company’s sales discounts and allowances during 2020 and 2019:

Royalty Revenue

Royalty revenue recorded by the Company relates exclusively to the Company’s License and Collaboration agreement with Biogen which provides for ongoing royalties based on sales of Fampyra outside of the U.S. The Company recognizes revenue for royalties under ASC 606, which provides revenue recognition constraints by requiring the recognition of revenue at the later of the following: 1) sale or usage of the products or 2) satisfaction of the performance obligations. The Company has satisfied its performance obligations and therefore recognizes royalty revenue when the sales to which the royalties relate are completed.

License Revenue

License revenue relates to the License and Collaboration agreement with Biogen which provides for milestone payments for the achievement of certain regulatory and sales milestones during the term of the agreement. Regulatory milestones are contingent upon the approval of Fampyra for new indications outside of the U.S. Sales milestones are

86

contingent upon the achievement of certain net sales targets for Fampyra sales outside of the U.S. The Company recognizes license revenue under ASC 606, which provides constraints for entities to recognize license revenue which is deemed to be variable by requiring the Company to estimate the amount of consideration to which it is entitled in exchange for transferring the promised goods or services to a customer. The Company recognizes an estimate of revenue to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the milestone is achieved. For regulatory milestones, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the Company’s control or the licensee’s control, such as regulatory approvals, are generally not considered probable of being achieved until those approvals are received. For sales-based milestones, the Company recognizes revenue upon the achievement of the specific sale milestones.

Inventory

The Company capitalizes inventory costs associated with the Company's products prior to regulatory approval when, based on management's judgment, future commercialization is considered probable and the future economic benefit is expected to be realized; otherwise, such costs are expensed as research and development.

The cost of Ampyra inventory manufactured by Alkermes is based on specified prices calculated as a percentage of net product sales of the product shipped by Alkermes to Acorda. In the event Alkermes does not manufacture the products, Alkermes is entitled to a compensating payment for the quantities of product provided by the alternative manufacturer. This compensating payment is included in our inventory balances. The Company records a reserve for excess and obsolete inventory based on the historic and forecasted sales pattern and specifically identified obsolete inventory based on the expiration dates of its products. The Company periodically reviews inventory for slow moving or obsolete amounts based on expected sales. The Company reviews projected market share as well as current buying patterns from its customers. The Company analyzes its ability to sell the inventory on hand and committed to customers prior to the expiration period of the respective inventory. As a result, significant judgment is employed in determining the appropriateness of the Company’s ability to sell inventory on hand and commitments based on the sales projections. If annual and expected volumes are less than expected, the Company may be required to make additional allowances for excess or obsolete inventory in the future. For the year ended December 31, 2019, upon review of expected future product sales volumes and the projected expiration of Ampyra inventory, we did not record any write off for potential obsolete and excess inventory.

Cost of Sales

Inbrija

Cost of sales includes the cost of inventory, expense due to inventory reserves when necessary, royalty expense, packaging costs, freight and required inventory stability testing costs. Cost of sales include those costs directly associated with the production of revenues, such as raw material consumed, factory overhead and other direct production costs. In periods of idle plant capacity, costs are charged directly to cost of sales in the period incurred.

Ampyra

Cost of sales includes the cost of inventory, expense due to inventory reserves when necessary, royalty expense, milestone amortization of intangible assets associated with our agreement with Alkermes as well as the capitalization of milestone achievements with the Canadian Spinal Research Organization (“CSRO”) during the three months ended March 31, 2010, packaging costs, freight and required inventory stability testing costs. Our inventory costs, royalty obligations and milestone obligations are set forth in the agreements entered into with Alkermes. These agreements require us to pay Alkermes a percentage of our net selling price for each inventory lot purchased from Alkermes. The cost for each lot is calculated based on an agreed upon estimated net selling price which is based on an actual historical net selling price. At the end of each quarter, we perform a calculation to adjust the inventory value for any lots received in the current quarter to that quarter’s actual net selling price. This payment is recorded as an adjustment to inventory as well as an accrual on our balance sheet and is required to be paid within 45 days of the quarter end. In the event we have sold any inventory purchased from Alkermes during that respective quarter, we would also record an adjustment to the cost of goods sold and an additional accrual on the balance sheet to be paid to Alkermes. The agreement with Alkermes allows us to purchase up to 25% of our annual inventory requirements from an alternative manufacturer but stipulates a compensating payment to be made to

87

Alkermes for any inventory purchased from this alternative manufacturer. This payment is determined at the end of the quarter in which any new lots have been purchased exclusive from Alkermes using the actual net selling price for the respective quarter net of an agreed upon amount as stipulated by the Alkermes agreement. This payment is recorded as an adjustment to inventory as well as an accrual on our balance sheet.

Zanaflex

Cost of sales consists of cost of inventory, expense due to inventory reserves when necessary, royalty expense, packaging costs, freight and required inventory stability testing costs. Our inventory costs, royalty obligations and milestone obligations are set forth in the agreements entered into in connection with our Zanaflex acquisition.

Qutenza

Cost of sales consists of cost of inventory, expense due to inventory reserves when necessary, royalty expense, packaging costs, freight and required inventory stability testing costs.

Research and Development

We consider the active management and development of our research, preclinical and clinical pipeline an important component of the long-term process of introducing new products. We manage our overall research, development and in-licensing efforts in a highly disciplined manner designed to advance only high quality, differentiated agents into clinical development. The duration of each phase of research and preclinical and clinical development and the probabilities of success for approval of drug candidates entering clinical development will be impacted by a variety of factors, including the quality of the molecule, the validity of the target and disease indication, early clinical data, investment in the program, competition and commercial viability. Due to the risks inherent in the clinical trial process and the early stage nature of our pipeline development programs, we are unable to estimate with any certainty completion dates, the proportion of our R&D investments assigned to any one program or to the future cash inflows from these potential programs.

Research and development expense consists primarily of:

For those studies that we administer ourselves, we account for our clinical study costs by estimating the patient cost per visit in each clinical trial and recognizing this cost as visits occur, beginning when the patient enrolls in the trial. This estimated cost includes payments to the trial site and patient‑related costs, including laboratory costs related to the conduct of the trial. Cost per patient varies based on the type of clinical trial, the site of the clinical trial, and the length of the treatment period for each patient. For those studies for which we use a CRO, we account for our clinical study costs according to the terms of the CRO contract. These costs include upfront, milestone and monthly expenses as well as reimbursement for pass through costs. All research and development costs are expensed as incurred except when we are accounting for nonrefundable advance payments for goods or services to be used in future research and development activities. In these cases, these payments are capitalized at the time of payment and expensed ratable over the period the research and development activity is performed. As actual costs become known to us, we adjust our accrual; such changes in estimate may be a material change in our clinical study accrual, which could also materially affect our results of operations.

88

We use our employee and infrastructure resources across several projects, and many of our costs are not attributable to an individually named project, but are broadly applicable research projects. Accordingly, we do not account for internal research and development costs on a project-by-project basis. Unallocated costs are represented as operating expenses in the table below.

The following table shows, for each of the years ended, (i) the total third party expenses for preclinical and clinical development, on a project-by-project basis, (ii) our unallocated research and development operating expenses, and (iii) acquisitions, licenses and milestone payments, on a project-by-project basis:

With respect to previously established clinical study accruals in prior periods and for the year ended December 31, 2020 we did not make any significant adjustments to our clinical study costs.

Sales and Marketing Expenses

Sales and marketing expenses include personnel costs, related benefits and share‑based compensation for our sales, managed markets and marketing personnel, the cost of Ampyra, Zanaflex, and Qutenza sales and marketing initiatives as well as the pre-market marketing costs for future products.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel costs, related benefits and share‑based compensation for personnel serving executive, finance, medical affairs, safety, business development, legal, quality assurance, information technology and human resource functions. Other costs include facility costs not otherwise included in research and development or sales and marketing expense and professional fees for legal and accounting services.

Asset Impairment

In Process Research and Development

The cost of in-process research and development (IPR&D) acquired directly in a transaction other than a business combination is capitalized if the project will be further developed or have an alternative future use; otherwise it is expensed. The estimated fair value of IPR&D projects acquired in a business combination is capitalized. Several methods may be used to determine the estimated fair value of the IPR&D assets acquired in a business combination. The Company utilizes the "income

89

method” which applies a probability weighting that considers the risk of development and commercialization to the estimated future net cash flows that are derived from projected sales revenues and estimated costs. These projections are based on factors such as relevant market size, patent protection, estimated pricing and expected industry trends. The estimated future net cash flows are then discounted to the present value using an appropriate discount rate. These assets are treated as indefinite-lived intangible assets until completion or abandonment of the projects, at which time the assets are amortized over the remaining useful life or impaired, as appropriate. These assets are tested at least annually or when a triggering event occurs that could indicate a potential impairment. Events that could result in an impairment, or trigger an interim impairment assessment, may include actions by regulatory authorities with respect to us or our competitors, the receipt of additional clinical or nonclinical data regarding our drug candidate or a potentially competitive drug candidate, changes in the clinical development program for a drug candidate or new information regarding potential sales for the drug which could have a negative effect on cash flows and which could result in an impairment. If impairment indicators are present or changes in circumstance suggest that an impairment may exist, we perform an impairment analysis by comparing the sum of the estimated discounted future cash flows, or fair value, of each intangible asset to its carrying value on the consolidated balance sheet. We will recognize an impairment loss if the carrying value of the intangible asset exceeds its fair value.

Finite-Lived Intangible Assets

Intangible assets with finite lives are amortized on a straight line basis over the period in which the Company expects to receive economic benefit and are reviewed for impairment when facts and circumstances indicate that the carrying value of the asset may not be recoverable. The determination of the expected life will be dependent upon the use and underlying characteristics of the intangible asset. In the Company’s evaluation of the intangible assets, it considers the term of the underlying asset life and the expected life of the related product line. If impairment indicators are present or changes in circumstance suggest that impairment may exist, the Company performs a recoverability test by comparing the sum of the estimated undiscounted cash flows of each intangible asset to its carrying value on the consolidated balance sheet. If the undiscounted cash flows used in the recoverability test are less than the carrying value, the Company would determine the fair value of the intangible asset and recognize an impairment loss in the statement of operations if the carrying value of the intangible asset exceeds its fair value. Fair value is generally estimated based on either appraised value or other valuation techniques. Events that could result in an impairment, or trigger an interim impairment assessment, may include actions by regulatory authorities with respect to us or our competitors, new or better products entering the market, changes in market share or market pricing, changes in the economic lives of the assets, changes in the legal framework covering patents, rights or licenses, and other market changes which could have a negative effect on cash flows and which could result in an impairment.

Goodwill

Goodwill represents the amount of consideration paid in excess of the fair value of net assets acquired in a business combination accounted for using the acquisition method of accounting. Goodwill is not amortized and is subject to impairment testing on an annual basis or when a triggering event occurs that may indicate the carrying value of the goodwill is impaired. We perform our impairment testing at the reporting level where we have determined that we have a single reporting unit and operating segment. The impairment test for goodwill uses an approach which compares the estimated fair value of the reporting unit including goodwill to its carrying value. If the carrying value of the reporting unit exceeds the estimated fair value of the reporting unit, an impairment loss is recognized in an amount equal to the excess of the carrying value over the estimated fair value. The Company recorded an impairment charge of $277.6 million for the year ended December 31, 2019 in the statement of operations and therefore, the goodwill was fully impaired. See Note 4 to our Consolidated Financial Statements included in this report for a discussion of goodwill.

Derivative Liability

During 2019, a derivative liability was initially recorded as a result of the issuance of the 6.00% Convertible Senior Secured Notes due 2024 (see Note 9 to our Consolidated Financial Statements included in this report). The Company initially determined the fair value of the liability upon issuance. The fair value measurement of the derivative liability is classified as Level 3 under the fair value hierarchy as it has been valued using certain unobservable inputs. These inputs include: (1) share price as of the valuation date, (2) assumed timing of conversion of the Notes, (3) historical volatility of share price and (4) the risk-adjusted discount rate used to present value the probability-weighted cash flows. Significant increases or decreases in any of those inputs in isolation could result in a significantly lower or higher fair value measurement. The fair value of the derivative liability was determined using a binomial model that calculates the fair value of the Notes with the conversion

90

feature as compared to the fair value of the Notes without the conversion feature, with the difference representing the value of the conversion feature, or the derivative liability. The conversion feature will be measured at fair value on a quarterly basis and the change in the fair value of the conversion feature for the period will be recorded in the consolidated statements of operations. 

Changes in Fair Value of Acquired Contingent Consideration

Changes in the fair value of acquired contingent consideration represents changes in the estimated fair value of the Company’s acquired contingent liability. Contingent consideration is recognized at fair value as of the date of acquisition and recorded as a liability on the consolidated balance sheet. The contingent consideration is re-valued on a quarterly basis using a probability weighted discounted cash-flow approach until fulfillment or expiration of the contingency. Changes in the fair value of the contingent consideration are recognized in the statement of operations.

Other Income (Expense)

Interest income consists of income earned on our cash, cash equivalents and short-term investments. Interest expense consists of cash and non-cash interest expense for the convertible senior secured notes due 2024 issued in December 2019, convertible senior notes due 2021 issued in June 2014, our capital and R&D loans and non-cash interest expense pertaining to the Fampyra royalty monetization.

Income Taxes

As part of the process of preparing our financial statements we are required to estimate our income taxes in each of the jurisdictions in which we operate. In accordance with ASC 740, we account for income taxes by the asset and liability method. Under this method, deferred income taxes are recognized for tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each year-end, based on enacted laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

We will continue to evaluate the realizability of our deferred tax assets and liabilities on a quarterly basis, and will adjust such amounts in light of changing facts and circumstances, including but not limited to future projections of taxable income, tax legislation, rulings by relevant tax authorities and the progress of ongoing tax audits, if any. We consider all available evidence, both positive and negative, to determine whether, based on the weight of that evidence, a valuation allowance is required to reduce the deferred tax assets to the amount that is more likely than not to be realized in future periods.

Share-Based Compensation

We account for stock options, restricted stock and restricted stock units granted to employees and non-employees by recognizing the costs resulting from all share-based payment transactions in the financial statements at their fair values. We estimate the fair value of each option on the date of grant using the Black‑Scholes closed-form option‑pricing model based on assumptions for the expected term of the stock options, expected volatility of our common stock, prevailing interest rates, and an estimated forfeiture rate.

We have based our current assumptions on the following:

91

Of these assumptions, the expected term of the option and expected volatility of our common stock are the most difficult to estimate since they are based on the exercise behavior of the employees and expected performance of our common stock. Increases in the term and the volatility of our common stock will generally cause an increase in compensation expense.

Item 9A. Controls and Procedures.

Evaluation of disclosure controls and procedures

As required by Rule 13a-15 under the Securities Exchange Act of 1934 (the “Exchange Act”), we carried out an evaluation of the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of our 2020 fiscal year (the period covered by this report). This evaluation was carried out under the supervision and with the participation of our management, including our Chief Executive Officer, our former Chief, Business Operations and Principal Accounting Officer, and our Vice President, Finance and Controller and interim principal financial and accounting officer. Based on that evaluation, these officers have concluded that, as of December 31, 2020, our disclosure controls and procedures were effective to achieve their stated purpose.

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules, regulations, and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is accumulated and communicated to management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding disclosure.

Change in internal control over financial reporting

In connection with the evaluation required by Exchange Act Rule 13a-15(d), our management, including our Chief Executive Officer,  our former Chief, Business Operations and Principal Accounting Officer, and our Vice President, Finance and Controller and interim principal financial and accounting officer, concluded that there were no changes in our internal control over financial reporting during the quarter ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the effectiveness of controls

Our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met. Because of inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act).

Under the supervision of and with the participation of our Chief Executive Officer,our former Chief, Business Operations and Principal Accounting Officer, and our Vice President, Finance and Controller and interim principal financial and accounting officer, our management conducted an assessment of the effectiveness of our internal control over financial reporting as of the end of 2020 (the period covered by this report) based on the framework and criteria established in Internal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this assessment, our management has concluded that, as of December 31, 2020, our internal control over financial reporting was effective. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions.

Ernst & Young LLP, the independent registered public accounting firm that audits our consolidated financial statements, has issued its attestation report on the Company’s internal control over financial reporting as of December 31, 2020. This attestation report appears below.

93

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Acorda Therapeutics, Inc.

Opinion on Internal Control Over Financial Reporting

We have audited Acorda Therapeutics, Inc. and subsidiaries’ internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Acorda Therapeutics, Inc. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive loss, stockholders' equity and cash flows for each of the two years in the period ended December 31, 2020, and the related notes and our report dated March 16, 2021 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

INDEX TO FINANCIAL STATEMENTS

F-1

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Acorda Therapeutics, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Acorda Therapeutics, Inc. and subsidiaries (the Company) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive loss, stockholders’ equity and cash flows for each of the two years in the period ended December 31, 2020, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) and our report dated March 16, 2021 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
