COVID-19 Impact

While the impact of the ongoing COVID-19 pandemic did not have a material adverse effect on the Company's financial position or results of operations for the three and nine months ended September 30, 2021. The Company continues to closely monitor the events and circumstances surrounding the COVID-19 pandemic and its impact on all aspects of our business operations. Since the situation surrounding the COVID-19 pandemic remains fluid and the duration uncertain, the long-term nature and extent of the impacts of the pandemic on the Company's business operations and financial position cannot be reasonably estimated at this time.

2. Summary of Significant Accounting Policies

Basis of Presentation

The Company’s unaudited condensed consolidated financial statements have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (SEC) for interim financial information. As permitted under Generally Accepted Accounting Principles in the United States (U.S. GAAP), certain notes and other information have been omitted from the interim unaudited condensed consolidated financial statements presented in this Quarterly Report on Form 10-Q. Therefore, these condensed consolidated financial statements should be read in conjunction with the Company’s most recent Annual Report on Form 10-K, for the year ended December 31, 2020, filed with the SEC.

In management’s opinion, the condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows. The results of operations for any interim period are not necessarily indicative of the Company’s future quarterly or annual results.

The Company, which is primarily located in the U.S., operates in one operating segment.

Reclassifications

Certain prior year amounts presented as separate noncash line items in the condensed consolidated statements of cash flows have been reclassified to conform to the current year condensed financial statement presentation. These reclassifications had no effect on operating cash flows or on our other condensed consolidated financial statements for the three and nine months ended September 30, 2021 and 2020.

Consolidation

The Company’s condensed consolidated financial statements include those of the Company's wholly-owned subsidiaries and variable interest entities (VIE) where the Company is the primary beneficiary, if any. All significant intercompany transactions and balances have been eliminated in consolidation.

The Company continuously assesses whether it is the primary beneficiary of a VIE, as changes to existing relationships or future transactions may affect its conclusions.

Table of Content s

Use of Estimates

The Company bases its estimates on: historical experience; forecasts; information received from its service providers; information from other sources, including public and proprietary sources; and other assumptions that the Company believes are reasonable under the circumstances. Actual results could differ materially from the Company’s estimates. The Company periodically evaluates the methodologies employed in making its estimates.

The extent to which the COVID-19 pandemic may directly or indirectly impact our business, financial condition and results of operations is highly uncertain and subject to change. As a result, certain of our estimates and assumptions, including the provision for sales deductions, the creditworthiness of customers entering into revenue arrangements, and the fair values of our financial instruments, require increased judgment and carry a higher degree of variability and volatility that could result in material changes to our estimates in future periods.

Advertising Expense

Advertising expense includes the cost of promotional materials and activities, such as printed materials and digital marketing, marketing programs and speaker programs. The cost of the Company's advertising efforts are expensed as incurred.

The Company incurred approximately $22.6 million and $59.7 million in advertising expense for the three and nine months ended September 30, 2021, respectively, and approximately $15.4 million and $37.9 million for the three and nine months ended September 30, 2020, respectively. These expenses are recorded as a component of Selling, general and administrative expenses in the condensed consolidated statements of earnings.

Recently Issued Accounting Pronouncements

Accounting Pronouncements Adopted

ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes - The new standard, issued in December 2019, simplifies the accounting for income taxes. The Company adopted the guidance on January 1, 2021, on a prospective basis. The adoption of the new standard did not have a material impact to the financial statements.

ASU 2020-01, Investments — Equity Securities (Topic 321), Investments — Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815), Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 - The new standard, issued in January 2020, clarifies the interaction of the equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain contracts and purchased options accounted for under Topic 815. The amendment clarifies that an entity can elect to adopt the measurement alternative, which is if an entity identifies observable price changes in orderly transactions for the identical or a similar investment of the same issuer, it should measure the equity security at fair value as of the date that the observable transaction occurred before applying or upon discontinuing the equity method. The adoption of the new standard as of January 1, 2021 did not have a material impact to the financial statements.

New Accounting Pronouncements Not Yet Adopted

ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity - The new standard, issued in August 2020, simplifies the accounting and disclosures for convertible instruments and contracts. This guidance will be effective on January 1, 2022 on a prospective basis. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.

3. USWM Acquisition

On June 9, 2020 (the Closing Date), the Company completed its acquisition of all of the outstanding equity of USWM Enterprises LLC (USWM Enterprises), a privately-held biopharmaceutical company, pursuant to a Sale and Purchase Agreement with US WorldMeds Partners, LLC (Seller), dated April 28, 2020 (the Agreement). Under the terms of the Agreement, the Company acquired the right to further develop and commercialize APOKYN, XADAGO, and the Apomorphine Infusion Pump (SPN-830; the In Process Research and Development (IPR&D) asset) in the U.S. and MYOBLOC worldwide (the Products) for an upfront cash payment of $297.2 million, subject to working capital adjustments, and the potential for additional contingent consideration payments of up to $230 million. In the second quarter of 2021 and within one year from the Closing Date, the Company finalized its accounting for the business combination, including the purchase price allocation.

Table of Content s

The potential $230 million in contingent consideration payments includes up to $130 million for the achievement of certain SPN-830 regulatory and commercial activities (regulatory and developmental contingent consideration payments) and up to $100 million related to future sales performance of the Products (sales-based contingent consideration payments). The regulatory and developmental contingent consideration payments include a $25 million milestone due upon the FDA's acceptance of the SPN-830 New Drug Application (NDA) for review. The remaining $105 million of the $130 million regulatory and developmental contingent consideration includes payments upon the FDA's regulatory approval and subsequent commercial launch by the Company of SPN-830, if approved. One of the regulatory milestones has a time-based mechanism for full or partial achievement. The $100 million sales-based contingent consideration payments include a $35 million milestone due upon achievement of certain U.S. net product sales of APOKYN during 2021. The remaining $65 million of the $100 million sales-based contingent consideration payments relate to the achievement of certain net product sales of the Products in 2022 and 2023. Refer to “Contingent Consideration” section below for further discussion.

Purchase Price Consideration

The following table summarizes the purchase price consideration (unaudited):


	Amount
Cash consideration	$	306,485
Fair value of contingent consideration	74,800
Total purchase consideration	$	381,285

Cash consideration to Seller - net of cash acquired	$	299,491

Contingent Consideration

In addition to the cash paid to the Seller, contingent payments of up to $230 million are also due to the Seller upon the achievement of certain milestones related to the development of SPN-830 and sale of the Products. The possible outcomes for the contingent consideration range from $0, if no milestone is achieved, to $230 million on an undiscounted basis if all milestones are achieved.

The Company initially recorded a contingent consideration liability of $115.7 million as of the Closing Date to reflect the estimated fair value of the contingent consideration based on information available at that time. The estimated fair value of the contingent consideration was determined using a Monte Carlo simulation for the sales-based contingent consideration payments and an income approach for the regulatory and developmental contingent consideration payments. The key assumptions considered in estimating the fair value include the estimated probability and timing of milestone achievement, such as the probability and timing of obtaining regulatory approval, discount rate, the estimated revenue volatility and the estimated amount and timing of projected revenues from the Products. Subsequent to the Closing Date, the Company adjusted the contingent consideration fair value based on new information related to the facts and circumstances that existed as of the acquisition date related to the timing of meeting the conditions of the milestone payments that are contingent upon regulatory approval and commercial launch of the acquired IPR&D asset as well as the estimated timing of projected revenues from the Products. As a result, the Company recorded in the fourth quarter of 2020, a measurement period adjustment of $40.9 million, which decreased the estimated fair value of the contingent consideration liability as of the Closing Date to $74.8 million. Refer to contingent consideration discussion in Note 6, Fair Value of Financial Instruments and Contingent Consideration.

Acquired Inventory

The fair value of the inventory was determined using the comparative sales method, which estimated the expected sales price of the product, reduced by all costs expected to be incurred to complete or to dispose of the inventory, as well as a profit on the sale.

Acquired Intangible Assets

The acquired intangible assets include the acquired IPR&D asset and the acquired developed technology and product rights. The Company determined the fair value of the acquired intangible assets as of the Closing Date using the income approach. The fair value measurements of the acquired intangible assets were determined based on significant unobservable inputs and therefore, represent a Level 3 fair value measurement. Some of the more significant inputs and assumptions used in the intangible assets valuation include: the timing and probability of success of clinical and regulatory approvals for the IPR&D asset, the estimated future cash flows from Product sales, the timing and projection of costs and expenses, discount rates and tax rates.

The following table summarizes the purchase price allocation, and the average remaining useful lives for identifiable intangible assets (unaudited, dollars in thousands):


	Fair Value		Estimated Useful Lives as of Closing Date (in years)
Acquired IPR&D	$	124,000	n/a
Acquired developed technology and product rights	231,000		10.5 - 12.5
Total intangible assets	$	355,000

Table of Content s

Acquired intangible assets, excluding the acquired IPR&D asset, are amortized over their estimated useful lives on a straight-line basis. The IPR&D asset is considered indefinite-lived, until the successful completion or abandonment of the associated research and development efforts.

Goodwill

Goodwill was calculated as the excess of the consideration paid consequent to completing the acquisition, compared to the net assets recognized. Goodwill represents the future economic benefits from the other acquired assets, and which could not be individually identified and separately valued. Goodwill is primarily attributable to the additional acquired growth platforms and an expanded revenue base. Goodwill is not deductible for tax purposes.

Investment in Navitor

Development Agreement

In April 2020, the Company entered into the Development Agreement with Navitor Inc. The Company can terminate the Development Agreement upon 30 days’ notice. Under the terms of the Development Agreement, the Company and Navitor Inc. will jointly conduct a Phase II clinical program for NV-5138 (SPN-820) for TRD. The Company will bear all of the Phase I and Phase II development costs incurred by either party, up to a maximum of $50 million. In addition, the Company will incur certain other research and development support costs. There are certain additional payment amounts which could be incurred by the Company. These costs are contingent upon Navitor Inc. achieving defined development milestones. The Company has an option to acquire or license NV-5138 (SPN-820), for which additional payments would be required. In the second quarter of 2020, the Company paid Navitor Inc. a one time, nonrefundable, and non-creditable fee of $10 million for this option to acquire or license NV-5138 (SPN-820) which was expensed and recorded in Research and development expense in the condensed consolidated statements of earnings.

Equity investment

In addition to entering into the Development Agreement in April 2020, the Company acquired Series D Preferred Shares of Navitor Inc. for $15 million, representing an approximately 13% ownership position in Navitor Inc.

In March 2021, Navitor Inc. underwent a legal restructuring. In the restructuring, Navitor Inc. became a wholly owned subsidiary of a newly formed limited liability company, Navitor LLC, and the outstanding shares of stock in Navitor Inc. were exchanged for units of membership interest in Navitor LLC having equivalent rights and preferences (Navitor Restructuring). As part of the Navitor Restructuring, the Series D Preferred Shares previously held by the Company were exchanged for Series D Preferred Units in Navitor LLC. In addition, certain assets that did not relate to NV-5138 (SPN-820) were transferred from Navitor Inc. to a newly formed entity that became a separate, wholly owned subsidiary of Navitor LLC.

Table of Content s

The Company had determined that Navitor LLC is a VIE. The Company does not consolidate this VIE because the Company lacks the power to direct the activities that most significantly impact the investee’s economic performance.

Prior to the Navitor Restructuring, the investment was accounted for under the practical expedient allowed for equity securities without readily determinable fair value, which is cost minus impairment plus any changes in observable price changes from an orderly transaction of similar investments in Navitor Inc. Following the legal restructuring and exchange of the preferred shares for member equity units of Navitor LLC, the investment was accounted for under the equity method of accounting due to the Company’s ability to exert significant influence under the new Navitor LLC legal structure, but not control the financial and operating decisions of Navitor LLC. The majority of the assets and liabilities recorded in Navitor LLC’s financial statements represent working capital items and cash that are being used for research and development purposes and are significantly lower than the Company’s investment in Navitor LLC. This created a significant basis difference for the Company’s investment in the underlying net assets, requiring the Company to account for the investee as if it were a consolidated subsidiary in a manner consistent with the provisions of ASC 805, Business Combinations, to apply the acquisition method of accounting. The Company has determined that substantially all of the fair value of the investment is attributable to a single IPR&D asset. As a result, the investee is not considered a business as defined in ASC 805. In the first quarter of 2021, the $15 million investment, which was previously recorded in Other assets in the condensed consolidated balance sheets, was expensed and recorded in Research and development expense in the condensed consolidated statements of earnings.

The maximum exposure to losses related to the investee is a maximum of approximately $50 million in expense for Phase I and Phase II development of NV-5138 (SPN-820), and the cost of other development and formulation activities provided by the Company.

The Company has provided no financing to the investee other than amounts required under the Development Agreement.

6. Fair Value of Financial Instruments and Contingent Consideration

The fair value of an asset or liability represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between unrelated market participants.

The Company reports the fair value of assets and liabilities using a three level measurement hierarchy that prioritizes the inputs used to measure fair value. The fair value hierarchy consists of the following three levels:

•Level 1—Valuations based on unadjusted quoted prices in active markets that are accessible at measurement date for identical assets.

•Level 2—Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and model-based valuations in which all significant inputs are observable in the market, either directly or indirectly (e.g., interest rates; yield curves).

•Level 3—Valuations using significant inputs that are unobservable in the market and inputs that reflect the Company’s own assumptions. These are based on the best information available, including the Company’s own data.

The fair value of the restricted marketable securities which are classified as Level 2 financial assets are recorded in Other assets on the condensed consolidated balance sheets. There were no Level 3 financial assets as of September 30, 2021 or December 31, 2020. There have been no transfers of assets or liabilities into or out of Level 3 of the fair value hierarchy.

Other Financial Instruments

The carrying amounts of other financial instruments, including accounts receivable, accounts payable, and accrued expenses, approximate fair value due to their short-term maturities.

The Company records its convertible debt at carrying value. The fair value of the outstanding convertible debt is based on actual trading information as well as quoted prices, both provided by bond traders. Refer to Note 8, Convertible Senior Notes Due 2023.

The Company also had an investment in Navitor LLC, a privately held company, which it classified as Level 3 as it does not have a readily determinable fair value. In the first quarter of 2021, the $15 million investment in Navitor LLC was expensed. Refer to Note 5, Investments.

Contingent Consideration

The contingent consideration liabilities are measured at fair value on a recurring basis. The changes in fair value are reported on the condensed consolidated statement of earnings in Contingent Consideration expense (gain). In the fourth quarter of 2020, the Company recorded a measurement period adjustment of $40.9 million. Refer to Note 3, USWM Acquisition. The Company recorded $0.1 million loss and $7.7 million gain due to the change in fair value of the contingent consideration liabilities for the three and nine months ended September 30, 2021, respectively. The change in fair value of $7.7 million for the nine months ended September 30, 2021 is primarily due to the write-down of the sales based contingent consideration liabilities offset by an increase in the estimated fair value of regulatory and developmental milestones due to the passage of time. The Company assessed that these sales-based milestones will not be achieved based on the revised net sales projections. The probability of achieving these milestones were significantly lower compared to prior estimates. The Company updated its projected net sales of the Products based on recent historical sales trend experience.

The following table provides a reconciliation of the beginning and ending balances related to the contingent consideration for the USWM Acquisition and composition of the contingent consideration liabilities (dollars in thousands):

The increase in goodwill represents measurement period adjustments recorded in 2021 related to the finalization of the business combination accounting of the USWM Acquisition. Refer to Note 3, USWM Acquisition.

Table of Content s

Patent defense costs are deferred legal fees incurred in conjunction with defending patents for Oxtellar XR and Trokendi XR. U.S. patents covering Oxtellar XR and Trokendi XR will expire no earlier than 2027. In regard to Trokendi XR, the Company entered into settlement agreements that allow third parties to enter the market by January 1, 2023, or earlier under certain circumstances.

Amortization expense for intangible assets was approximately $6.0 million and $18.0 million for the three and nine months ended September 30, 2021, respectively, and approximately $6.1 million and $9.8 million for the three and nine months ended September 30, 2020, respectively. The increase in expense is due to amortization of the acquired developed technology and product rights from the USWM Acquisition.

8. Convertible Senior Notes Due 2023

The 0.625% Convertible Senior Notes Due 2023 (2023 Notes), which were issued in March 2018, bear interest at an annual rate of 0.625%, payable semi-annually in arrears on April 1 and October 1 of each year. The 2023 Notes will mature on April 1, 2023, unless earlier converted or repurchased by the Company. The Company may not redeem the 2023 Notes at its option before maturity. The total principal amount of 2023 Notes is $402.5 million.

The 2023 Notes were issued pursuant to an Indenture between the Company and Wilmington Trust, National Association, as trustee. The Indenture includes customary terms and covenants, including certain events of default upon which the 2023 Notes may be due and payable immediately. The Indenture does not contain any financial or operating covenants, or any restrictions on the payment of dividends, the issuance of other indebtedness, or the issuance or repurchase of securities by the Company.

Noteholders may convert their 2023 Notes at their option only in the following circumstances: (1) during any calendar quarter, if the last reported sale price per share of the Company's common stock for at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including the last trading day of the immediately preceding calendar quarter, exceeds 130% of the conversion price, or a price of approximately $77.13 per share on such trading day; (2) during the five consecutive business days immediately after any 10 consecutive trading day period (such 10 consecutive trading day period, the "measurement period") in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Company's common stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Company's common stock, as specified in the Indenture; and (4) at any time from and including October 1, 2022, until the close of business on the second scheduled trading day immediately before the maturity date.

At its election, the Company will settle conversions by paying or delivering, as applicable, cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock, based on the applicable conversion rate. The initial conversion rate is 16.8545 shares per $1,000 principal amount of the 2023 Notes, which represents an initial conversion price of approximately $59.33 per share, and is subject to adjustment as specified in the Indenture. In the event of conversion, if converted in cash, the holders would forgo all future interest payments, any unpaid accrued interest, and the possibility of further stock price appreciation.

If a “make-whole fundamental change,” as defined in the Indenture occurs, then the Company will in certain circumstances increase the conversion rate for a specified period of time. If a “fundamental change,” as defined in the Indenture occurs, then noteholders may require the Company to repurchase their 2023 Notes at a cash repurchase price equal to the principal amount of the 2023 Notes to be repurchased, plus accrued and unpaid interest, if any.

Contemporaneous with the issuance of the 2023 Notes, the Company also entered into separate privately negotiated convertible note hedge transactions (collectively, the Convertible Note Hedge Transactions) with each of the call spread counterparties. The Company issued 402,500 convertible note hedge options. In the event that shares or cash are deliverable to holders of the 2023 Notes upon conversion at limits defined in the Indenture, counterparties to the convertible note hedges will be required to deliver up to approximately 6.8 million shares of the Company’s common stock, or to pay cash to the Company in a similar amount as the value that the Company delivers to the holders of the 2023 Notes, based on a conversion price of $59.33 per share.

Concurrently with entering into the Convertible Note Hedge Transactions, the Company also entered into separate privately negotiated warrant transactions (collectively, the Warrant Transactions) with each of the call spread counterparties. The Company issued a total of 6,783,939 warrants. The warrants entitle the holder to one share per warrant. The strike price of the Warrant Transactions will initially be $80.9063 per share of the Company’s common stock, and is subject to adjustment.

Table of Content s

The Convertible Note Hedge Transactions are expected to reduce the potential dilution of the Company’s common stock upon conversion of the 2023 Notes, and/or offset any potential cash payments the Company is required to make in excess of the principal amount of converted 2023 Notes, as the case may be.

The Warrant Transactions were intended to partially offset the cost to the Company of the purchased Convertible Note Hedge Transactions; however, the Warrant Transactions could have a dilutive effect with respect to the Company’s common stock, to the extent that the market price per share of the Company’s common stock, as measured under the terms of the Warrant Transactions, exceeds the strike price of the warrants.

10. Earnings per Share

Basic earnings per share (EPS) is calculated using the weighted-average number of common shares outstanding. Diluted EPS is calculated using the weighted-average number of common shares outstanding, including the dilutive effect of the Company’s stock option grants, SARs, RSUs, employee stock purchase plan (ESPP) awards, and the 2023 Notes, as determined per the treasury stock method.

Effect of Convertible Notes and Related Convertible Note Hedges and Warrants

In connection with the issuance of the 2023 Notes, the Company entered into Convertible Note Hedge and Warrant Transactions as described further in Note 8, Convertible Senior Notes Due 2023. The expected collective impact of the Convertible Note Hedge and Warrant Transactions is to reduce the potential dilution that would occur if the price of the Company's common stock was between the conversion price of $59.33 per share and the strike price of the warrants of $80.9063 per share.

The 2023 Notes and related Convertible Note Hedge and Warrant Transactions are excluded in the calculation of diluted EPS because inclusion would be anti-dilutive.

In addition to the above described effect of the 2023 Notes and the related Convertible Note Hedge and Warrant Transactions, the Company also excluded the common stock equivalents of the following outstanding stock-based awards in the calculation of diluted EPS, because their inclusion would be anti-dilutive:

Effective tax rate	25.5		%	24.1		%	28.3		%	25.4		%

Income tax expense for the three and nine months ended September 30, 2021, as compared to the same periods in the prior year, decreased primarily due to lower income before taxes in 2021. The effective income tax rate increased for the three months ended September 30, 2021, as compared to the same period in the prior year, primarily due to greater research and development credit benefit recognized during the three months ended September 30, 2020. The effective income tax rate increased for the nine months ended September 30, 2021, as compared to the same period in the prior year, mainly due to changes in the effective state tax rates as a result of the transfer of workforce between legal entities in the first quarter of 2021.

12. Leases

Headquarters and Fleet Vehicles

The Company has operating leases for its headquarters lease and its fleet vehicles. With respect to the fleet vehicle leases, given the volume of individual leases involved in the overall arrangement, the Company applies a portfolio approach to effectively account for the operating lease assets and liabilities. The Company also elected to combine the lease and non-lease components for the fleet vehicle and headquarters leases.

The Company's headquarters lease commenced on February 1, 2019 and will continue until April 30, 2034, unless earlier terminated in accordance with the terms of the lease. The lease includes options to extend the lease for up to 10 years.

On August 23, 2021, the Company entered into an addendum to the original headquarters lease agreement to lease additional office space, referred to as the Expansion Premises. The Expansion Premises is separate from the lease space in the original lease agreement. The term of the lease with respect to the Expansion Premises commenced on September 1, 2021 and coincides with the lease term per the original lease agreement.

Contract Manufacturing Lease

Contemporaneous with the USWM Acquisition, USWM Enterprises adopted ASC 842, Leases. USWM Enterprises had an existing contract manufacturing agreement with Merz Pharma GmbH & Co. KGaA (Merz), for the manufacture and supply of rimabotulinumtoxinB finished products (Merz Agreement). Pursuant to the Merz Agreement, Merz agreed to provide a dedicated manufacturing facility that included a stand-alone building, dedicated clean room suites, dedicated manufacturing and purification equipment, and filling and packaging production lines (collectively, the manufacturing facility) to manufacture finished products. The Merz Agreement will expire in July 2027, unless the Company and Merz mutually agree to extend the terms. The Merz Agreement may not be terminated for convenience.

Under the terms of the agreement, the Company is required to purchase a minimum quantity of finished products on an annual basis. This minimum purchase requirement represents the in-substance fixed contract consideration associated with the dedicated manufacturing facility which the Company accounts for as an embedded lease.

At the Closing Date of the USWM Acquisition, the Company preliminarily classified the embedded lease as a finance lease and preliminarily elected not to separate the lease and non-lease components. In the second quarter of 2021, the Company finalized its accounting of the USWM Acquisition. During the measurement period, the Company determined the fair market value of rent for the lease components and fair market value of the manufacturing facility associated with the Merz embedded lease. As a result, the Company made an accounting policy election, by class of underlying asset, to not combine lease and non-lease components for the manufacturing facility. A portion of the in-substance fixed contract consideration was allocated to the lease component based on the stand-alone selling price. Accordingly, the Company has finalized and updated the classification of the embedded lease from a finance lease to an operating lease. Refer to Note 3, USWM Acquisition, for further discussion.

15. Commitments and Contingencies

Product Licenses

The Company has obtained exclusive licenses from third parties for proprietary rights to support certain products and product candidates. Under these license agreements, the Company may be required to pay certain amounts upon the achievement of defined milestones. If these products are ultimately commercialized, the Company is also obligated to pay royalties to third parties, computed as a percentage of net product sales, for each respective product under a license agreement.

Through the USWM Acquisition, the Company acquired licensing agreements with other pharmaceutical companies for APOKYN, XADAGO and MYOBLOC. The Company is obligated to pay royalties to third parties, computed as a percentage of net product sales, for each of the products under the respective license agreements. Royalty expense incurred is recognized as Cost of goods sold in the condensed consolidated statements of earnings.

Royalty Agreement

In the third quarter of 2014, the Company received $30 million pursuant to a Royalty Interest Acquisition Agreement related to the purchase, by HealthCare Royalty Partners III, L.P. (HC Royalty), of certain of the Company’s rights under the Company’s agreement with United Therapeutics Corporation. These rights are related to the commercialization of Orenitram

Table of Content s

(treprostinil) Extended-Release Tablets. Per the terms of the agreement, full ownership of the royalty rights will revert to the Company if and when a certain cumulative payment threshold is reached. Consequent to this agreement, the Company recorded a nonrecourse liability related to this transaction and amortizes this liability as noncash royalty revenue. Refer to Note 4, Disaggregated Revenues, and Note 13, Composition of Other Balance Sheet Items.

USWM Enterprise Commitments Assumed

As part of the USWM Acquisition, the Company assumed the remaining commitments of USWM Enterprises and its subsidiaries, which are discussed below.

Under the Merz Agreement, the annual minimum purchase quantity requirements of MYOBLOC amounted to approximately €3.0 million annually. In October 2021, the Company entered into an amendment to the Merz Agreement. Refer to Note 12, Leases, for further discussion on the contract manufacturing lease and Note 16, Subsequent Events, for further discussion on the contract amendment.

In addition, USWM Enterprises had an existing license and distribution agreement for XADAGO. This included an annual minimum promotional spend to support the marketing of XADAGO for the first five years of the agreement. As of September 30, 2021, the remaining contractual commitment for XADAGO is $1.1 million for the period from July 2021 to June 2022. Refer to Note 3, USWM Acquisition, for further discussion on the USWM Acquisition.

In March 2019, which is prior to the USWM Acquisition Closing Date, MDD US Operations, LLC (formerly US WorldMeds, LLC) and its subsidiary, Solstice Neurosciences, LLC (US) (collectively, the MDD Subsidiaries) entered into a Corporate Integrity Agreement (CIA) with the Office of Inspector General of the U.S. Department of Health and Human Services. Under the CIA, the MDD Subsidiaries agreed to and paid $17.5 million to resolve U.S. Department of Justice allegations that it violated the False Claims Act and committed to the establishment and ongoing maintenance of an effective compliance program. The fine was paid by the MDD Subsidiaries prior to closing of the USWM Acquisition. As part of the USWM Acquisition, the Company assumed the remaining obligations of the CIA and could become liable for payment of certain stipulated monetary penalties in the event of any CIA violations. In addition, the Company will continue to incur significant costs through March 2024 to maintain a broad array of processes, policies and procedures necessary to comply with the CIA.

Claims and Litigation

From time to time, the Company may be involved in various claims, litigation and legal proceedings. These matters may involve patent litigation, product liability and other product-related litigation, commercial and other matters, and government investigations, among others. On a quarterly basis, the Company reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim, asserted or unasserted, or legal proceeding is considered probable and the amount can be reasonably estimated, the Company will accrue a liability for the estimated loss. Because of uncertainties related to claims, legal proceedings and litigation, accruals will be based on the Company's best estimates based on available information. We do not believe that any of these matters will have a material adverse effect on our financial position. The Company may reassess the potential liability related to these matters and may revise these estimates, which could result in material adverse adjustments to the Company's operating results.

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, the Company has agreed to cause Purchaser to commence a tender offer to purchase all of the outstanding shares of common stock of Adamas, par value $0.001 per share (the “Shares” and each, a “Share”), at an offer price of (i) $8.10 per Share, in cash, less any applicable withholding taxes and without interest (the “Cash Amount” an aggregate of approximately $400 million), plus (ii) two contingent value rights per Share (each, a “CVR” an aggregate of approximately $50 million), which represents the right to receive $0.50 per CVR, which CVRs will be governed by the terms of a contingent value rights agreement to be entered into between the Company and a rights agent mutually agreeable to the Company and Adamas (the “CVR Agreement”), in cash, less any applicable withholding taxes and without interest (the Cash Amount plus two CVRs, collectively, or any higher amount per Share paid pursuant to the Offer, the “Offer Price”). Following the consummation of the Offer and subject to the terms and conditions of the Merger Agreement, Purchaser will be merged with and into Adamas pursuant to Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”), with Adamas continuing as the surviving corporation in the Merger and a wholly owned subsidiary of the Company.

At or prior to the time at which Purchaser accepts the Shares tendered in the Offer for purchase, the Company and a rights agent mutually agreeable to the Company and Adamas shall enter into a CVR Agreement to allow for the payment of the milestones pursuant to each CVR. Subject to the terms of the CVR Agreement, one CVR issued in respect of a Share shall become payable upon the first occurrence of achievement of aggregate worldwide net sales of a specified product in excess of $150 million during any consecutive 12-month period ending on or before December 31, 2024.

COVID-19 Impact

While the impact of the ongoing COVID-19 pandemic did not have a material adverse effect on our financial position or results of operations for the three and nine months ended September 30, 2021, we continue to closely monitor the events and circumstances surrounding the COVID-19 pandemic and its impact on all aspects of our business operations. Since the situation surrounding the COVID-19 pandemic remains fluid and the duration uncertain, the long-term nature and extent of the impacts of the pandemic on our business operations and financial position cannot be reasonably estimated at this time. See “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for additional information on risk factors that could impact our business and our results.

Critical Accounting Policies and the Use of Estimates

Our condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP), requiring us to make estimates, judgments, and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and other related disclosures. Some judgments can be subjective and complex, and therefore, actual results could differ materially from those estimates under different assumptions or conditions. We believe the judgments, estimates, and assumptions associated with the following critical accounting policies have the greatest potential impact on our condensed consolidated financial statements:

•Revenue recognition;

•Business combination accounting and valuation of acquired assets, including goodwill and intangible assets; and

•Income taxes.

There were no changes to the disclosures with respect to the above listed critical accounting policies in our Annual Report on Form 10-K for the year ended December 31, 2020. A summary of our significant accounting policies appears in the notes to our audited consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2020.

(1) In April 2021, we notified the European Medicines Agency that we will cease the marketing of rimabotulinumtoxinB in European countries where it has been marketed as NeuroBloc.

The $6.6 million and 4% decrease in net product sales for the three months ended September 30, 2021, as compared to the same period in 2020, was primarily due to a $9.9 million and $2.0 million decrease in net product sales of APOKYN and Trokendi XR, respectively. Offsetting these decreases were increases primarily from net product sales of Oxtellar XR and Qelbree, which was launched in second quarter of 2021.

The $43.9 million and 12% increase in net product sales for the nine months ended September 30, 2021, as compared to the same period in 2020, was primarily due to a $44.7 million increase in net product sales of the acquired commercial products, $6.1 million increase in net product sales of Oxtellar XR and net product sales from the recently launched Qelbree. Partially offsetting this increase was $9.6 million decrease in net product sales of Trokendi XR for the nine months ended September 30, 2021, as compared to the same period in 2020.

Trokendi XR net product sales decreased by 2% to $80.9 million for the three months ended September 30, 2021 as compared to the same period in 2020. Trokendi XR net product sales decreased by 4% to $231.5 million for the nine months ended September 30, 2021 as compared to the same period in 2020. This decrease was attributable to a decline in unit demand partially offset by the favorable impact of the price increase taken in January 2021 and favorable improvements in sales deductions.

Oxtellar XR net product sales increased by 5% to $29.7 million for the three months ended September 30, 2021 as compared to the same period in 2020. Oxtellar XR net product sales increased by 8% to $82.1 million for the nine months ended September 30, 2021 as compared to the same period in 2020. This increase was primarily attributable to the favorable impact of both unit demand and a price increase in January 2021.

Net product sales of the acquired commercial products decreased to $32.5 million from $40.9 million for the three months ended September 30, 2021 as compared to the same period in 2020. The decrease was primarily due to a decrease in net product sales of APOKYN. APOKYN net product sales decreased by 29% to $24.6 million for the three months ended September 30, 2021 as compared to the same period in 2020. This decrease was due partially to higher level of channel inventory as well as increased market competition. Net product sales of the acquired commercial products increased to $96.2 million from $51.5 million for the nine months ended September 30, 2021. The increase for the nine month period was due primarily to the timing of the USWM Acquisition, which was completed on June 9, 2020.

Sales Deductions and Related Accruals

We record accrued product rebates and accrued product returns as current liabilities in Accrued product returns and rebates, on our condensed consolidated balance sheets. We record sales discounts as a reduction against Accounts receivable on the condensed consolidated balance sheets. Both amounts are generally affected by changes in gross product sales, changes in the provision for net product sales deductions, and the timing of payments/credits.

The following table provides a summary of activity with respect to sales deductions and related accruals during the periods indicated (dollars in thousands):


	Accrued Product Returns and Rebates
	Product Rebates		Product Returns		Reduction to Accounts Receivable for Sales Discounts		Total

Balance at September 30, 2020	$	110,543	$	26,430	$	11,098	$	148,071

Accrued Product Returns and Rebates Balances

The accrued product rebates balance decreased from $110.5 million as of September 30, 2020 to $98.6 million as of September 30, 2021 due to the timing of payments which more than offsets the increase in the provision.

The accrued product returns balance increased from $26.4 million as of September 30, 2020 to $33.4 million as of September 30, 2021 due to timing of related return activity offset by a decrease in the provision for product returns.

Provisions for Returns and Rebates

The provision for product rebates increased to $276.7 million for the nine months ended September 30, 2021 compared to $258.0 million for the same period in prior year. This increase was primarily attributable to greater utilization of our patient co-payment programs, as well as higher per patient payments under both Medicaid and commercial managed care programs.

The provision for product returns of $8.4 million for the nine months ended September 30, 2021 was lower compared to $17.7 million for the nine months ended September 30, 2020. This decrease was primarily due to the unfavorable actual returns experienced in the first quarter of 2020 for discontinued Trokendi XR commercial blister pack configurations, for which all production and distribution ceased in 2017.

Royalty Revenues

Royalty revenues were $2.9 million and $3.0 million for the three months ended September 30, 2021 and 2020, respectively. Royalty revenues were $8.2 million for both the nine months ended September 30, 2021 and 2020, respectively.

Royalty revenues include a royalty from net product sales of Mydayis, a product of Takeda Pharmaceuticals Company Ltd., and noncash royalty revenue pursuant to our agreement with Healthcare Royalty Partners III, L.P. (HC Royalty). HC Royalty receives royalty payments from United Therapeutics Corporation (United Therapeutics) based on net product sales of United Therapeutics’ product Orenitram.

Cost of Goods Sold

Cost of goods sold was $18.1 million and $21.4 million for the three months ended September 30, 2021 and 2020, respectively. Cost of goods sold was $58.1 million and $33.9 million for the nine months ended September 30, 2021 and 2020, respectively. Royalty payments associated with the acquired commercial products, APOKYN and XADAGO, made up the majority of the cost of goods sold.

The decline in cost of goods sold for the three months period was primarily due to lower royalties as a result of decreased APOKYN net product sales, partially offset by additional costs of $1.3 million for rejected MYOBLOC inventory lots in connection with the minimum purchase commitments. The increase in cost of goods sold for the nine months period was primarily due to higher cost recorded in 2021 for the acquired commercial products which is attributable to the timing of the USWM Acquisition that was completed on June 9, 2020, costs of $7.0 million for rejected MYOBLOC inventory lots, partially offset by lower royalties in the current year. Refer to Part I, Item 1, Unaudited Condensed Financial Statements, Note 15, Commitments and Contingencies in the Notes to the Condensed Consolidated Financial Statements for discussion regarding annual minimum purchase quantity requirements of MYOBLOC.

Also included in cost of goods sold for the three and nine months ended September 30, 2021 are de minimis costs for Qelbree inventory sold. We manufacture Qelbree inventory for commercial sale and for use in our samples program. Manufacturing costs related to Qelbree inventory build-up incurred before FDA approval and prior to first quarter of 2020, when the Company began capitalizing pre-launch inventory, were expensed to research and development expense. The manufactured Qelbree inventory prior to FDA approval consisted of $8.6 million raw materials inventory, which was expensed as research and development expense in 2019. Therefore, cost of goods sold for Qelbree for the three and nine months ended September 30, 2021 does not include raw material cost that was previously expensed. We expect our cost of goods sold to increase in the future as this inventory is sold, which will have a negative impact on our operating earnings.

The time period over which reduced-cost Qelbree inventory is consumed will depend on a number of factors, including the amount of future Qelbree sales, the ultimate use of this inventory in either commercial sales, clinical development or other research activities, and the ability to utilize inventory prior to its expiration date. At this time, we expect to sell as commercial inventory or consume as samples substantially all of the reduced-cost inventory by the first half of 2022.

______________________________

(1) Direct costs, which include personnel costs and related benefits, are recorded on a project-by-project basis. Many of our R&D costs are not attributable to any individual project because we share resources across several development projects. Indirect costs that support a number of our R&D activities are recorded in the aggregate, including stock-based compensation.

R&D expenses were $19.7 million and $16.8 million for the three months ended September 30, 2021 and 2020, respectively. The $2.8 million increase was primarily due to higher regulatory activities related to the acquired products from the USWM Acquisition and Qelbree, increase in costs associated with MYOBLOC post-marketing commitment studies (SPN-860), offset by reduced spending on SPN-812 (Qelbree) Phase III programs. Qelbree for treatment of ADHD in pediatric patients was launched in May 2021 and the NDA for Qelbree for adults was submitted in the first half of 2021.

R&D expenses were $69.4 million and $58.0 million for the nine months ended September 30, 2021 and 2020, respectively. The $11.4 million increase was primarily due to the $15 million write-down of the investment in Navitor LLC; increased spending on SPN-820, which has advanced to a Phase II clinical program, and on MYOBLOC post-marketing commitment studies; and higher regulatory activities related to the acquired products. These increases are partially offset by reduced spending on SPN-812 (Qelbree) Phase III programs and the $10 million option fee paid in 2020. Refer to Part I, Item 1, Unaudited Condensed Consolidated Financial Statements, Note 5, Investments, in the Notes to the Condensed Consolidated Financial Statements, for further discussion of the write-down of the investment in Navitor LLC in 2021 and the option fee payment in 2020.

Selling and Marketing

Selling and marketing expenses were $50.7 million and $38.1 million for the three months ended September 30, 2021 and 2020, respectively. Selling and marketing expenses were $137.5 million and $95.0 million for the nine months ended September 30, 2021 and 2020, respectively. The increases in both periods were primarily attributable to increased marketing expenses and professional consulting spend for the launch of Qelbree and the acquired commercial products from the USWM Acquisition. In addition, employee-related expenses also increased due to higher headcount to support the launch of Qelbree.

In addition, the reduced-cost Qelbree samples were included in selling and marketing expenses for the three and nine months ended September 30, 2021. At full cost, these Qelbree samples would have resulted in $0.8 million and $4.0 million higher SG&A for the three months ended and nine months ended September 30, 2021, respectively. At this time, we expect to sell as commercial inventory or consume as samples the reduced-cost Qelbree inventory by the first half of 2022.

General and Administrative

General and administrative expenses were $21.3 million and $16.3 million for the three months ended September 30, 2021 and 2020, respectively. General and administrative expenses were $65.5 million and $49.2 million for the nine months ended September 30, 2021 and 2020, respectively. The increases in both periods were primarily attributable to increased professional consulting spend and increased headcount to support the integration of the MDD operations.

Amortization of Intangible Assets

Amortization of intangible assets was $6.0 million and $6.1 million for the three months ended September 30, 2021 and 2020, respectively. Amortization of intangible assets was $18.0 million and $9.8 million for the nine months ended September 30, 2021 and 2020, respectively. The increase for nine month period was primarily due to timing of the USWM acquisition, which was completed on June 9, 2020.

Contingent Consideration Expense (Gain)

The change in the fair value of the contingent consideration liabilities associated with the USWM Acquisition was an expense of $0.1 million for the three months ended September 30, 2021 and a gain of $7.7 million for the nine months ended September 30, 2021. The contingent consideration gain was primarily due to the reduction of the sales based contingent consideration liabilities recorded in the second quarter of 2021 offset by an increase in the estimated fair value of regulatory and developmental milestones due to passage of time. The Company assessed that these sales-based milestones will not be achieved based on the revised net sales projections.

Other expense was $3.6 million and $3.4 million for the three months ended September 30, 2021 and 2020, respectively. Other expense increased to $8.8 million for the nine months ended September 30, 2021 from $1.7 million for the same period in 2020 primarily due to lower interest income on marketable securities holdings in 2021 and gains generated from sales of our marketable securities in 2020. Specifically, in the second quarter of 2020, we sold securities at a gain of $3.6 million to finance the up-front cash payment of approximately $300 million for the USWM Acquisition.

Income Tax Expense

Income tax expense was $7.4 million and $12.7 million for the three months ended September 30, 2021 and 2020, respectively. Income tax expense was $20.1 million and $32.8 million for the nine months ended September 30, 2021 and 2020 respectively. The decreases in both periods were mainly due to lower earnings before taxes in 2021.

The effective income tax rate was 25.5% and 24.1% for the three months ended September 30, 2021 and 2020, respectively. The effective income tax rate was lower in 2020 primarily due to a greater research and development credit benefit recognized in 2020. The effective income tax rate was 28.3% and 25.4% for the nine months ended September 30, 2021 and 2020, respectively. The effective income tax rate increase was mainly due to changes in the effective state tax rates as a result of the transfer of workforce between legal entities in the first quarter of 2021.

Liquidity and Capital Resources

We have financed our operations primarily with cash generated from product sales, supplemented by cash generated by revenue from royalty and licensing arrangements, as well as proceeds from the sale of equity and debt securities. Continued cash generation is highly dependent on the continued commercial success of our commercial products as well as the potential commercial success of our product candidates, if approved by the FDA.

While we expect continued profitability in future years, we anticipate there may be significant variability from year to year in the level of our profits particularly due to the commercial launch of Qelbree in May 2021, future commercial launch of Qelbree for treatment of ADHD in adults and SPN-830 (Apomorphine Infusion Pump), if both are approved by the FDA, continued market and payor pressures for our commercial products and the likely unfavorable impact of the upcoming loss of exclusivity for Trokendi XR in January 2023, or sooner under certain conditions.

We believe our existing cash and cash equivalents, marketable securities, and cash received from product sales will be sufficient to finance ongoing operations, develop and launch our new products, and fund label expansions for existing products. To continue to grow our business over the long-term, we plan to commit substantial resources to: product development and clinical trials of product candidates; business development, including acquisition and product in-licensing; and supportive functions such as compliance, finance, management of our intellectual property portfolio, information technology systems, and personnel. In each case, spending would be commensurate with the growth and needs of the business.

We may, from time to time, consider raising additional capital through: new collaborative arrangements; strategic alliances; additional equity and/or debt financings; or financing from other sources, especially in conjunction with opportunistic business development initiatives. We will continue to actively manage our capital structure and to consider all financing

opportunities that could strengthen our long-term financial profile. Any such capital raises may or may not be similar to transactions in which we have engaged in the past. There can be no assurance that any such financing opportunities will be available on acceptable terms, if at all.

Financial Condition

Cash and cash equivalents, marketable securities, and long term marketable securities as of the periods presented below, are as follows (dollars in thousands):

Total cash and cash equivalents, marketable securities and long term marketable securities increased by $76.4 million in the first nine months of 2021, primarily due to cash generated from ongoing operations.

As of September 30, 2021 and December 31, 2020, the outstanding principal on our 0.625% Convertible Senior Notes Due 2023 (2023 Notes) was $402.5 million. No 2023 Notes have been converted as of September 30, 2021. There were no changes to the separate convertible note hedge transactions (collectively, the Convertible Note Hedge Transactions) and separate warrant transactions (the Warrant Transactions). Refer to Part I, Item 1, Unaudited Condensed Financial Statements, Note 8, Convertible Senior Notes Due 2023, in the Notes to the Condensed Consolidated Financial Statements, for further discussion of the 2023 Notes and our other indebtedness.

Summary of Cash Flows

The following table summarizes the major sources and uses of cash for the periods set forth below (dollars in thousands):


	Nine Months ended September 30,				Change
	2021		2020		Amount
Net cash provided by (used in):
Operating activities	$	78,364	$	106,466	$	(28,102)
Investing activities	(158,043)		(84,044)		(73,999)
Financing activities	6,320		490		5,830
Net change in cash and cash equivalents	$	(73,359)	$	22,912	$	(96,271)

Operating Activities

Net cash provided by operating activities was $78.4 million and $106.5 million for the nine months ended September 30, 2021, and 2020, respectively. The decrease in cash flows provided by operating activities is primarily due to a decrease in earnings, as well as changes in working capital, which reflects the timing impacts of the following:

•cash collections on receivables and settlement of payables;

•increase in inventory primarily related to Qelbree, which was launched in the second quarter of 2021;

•increases in accrued product returns and rebates primarily due to timing of Medicaid and commercial managed care rebate payments; increased provision for rebates due to growth in prescription unit volume, higher Medicaid and managed care rebates and expenditures for patient co-pay programs; and unfavorable actual returns experience in 2020 for discontinued blister pack Trokendi XR configurations.

Investing Activities

Net cash used in investing activities was $158.0 million for the nine months ended September 30, 2021, as compared to $84.0 million net cash used in investing activities for the same period in 2020. The change in 2021 was primarily due to an increase in net purchases of marketable securities in 2021 resulting from investment of excess cash in marketable securities as compared to the same period in the prior year. The change in 2020 was primarily due to lower purchases of marketable securities from investment of excess cash in marketable securities, offset by proceeds from sale of marketable securities of $319.4 million, and offset by outlays for the USWM Acquisition of $297.2 million and the investment in Navitor of $15.0 million.

Financing Activities

Net cash provided by financing activities for the nine months ended September 30, 2021 increased by $5.8 million, as compared to the same period in 2020, primarily due to higher proceeds from issuance of common stock.

Contractual Obligations and Commitments

Refer to the “Contractual Obligations and Commitments” section in “Part II, Item 7 — Management’s Discussion and Analysis of Liquidity and Capital Resources”, of our Annual Report on Form 10-K for the year ended December 31, 2020, and Note 15, Commitments and Contingencies, in the Notes to the Condensed Consolidated Financial Statements in Part I, Item 1, Unaudited Condensed Financial Statements, of this Quarterly Report on Form 10-Q for the discussion of our contractual obligations.

Off-Balance Sheet Arrangements

Other than the unconsolidated variable interest entities discussed in Part I, Item 1, Unaudited Condensed Financial Statements, of this Quarterly Report on Form 10-Q, we do not currently have, nor have we ever had, any relationships with unconsolidated entities or financial partnerships, such entities often referred to as structured finance or special purpose entities. These would have been established for the purpose of facilitating off-balance sheet arrangements or for other contractually narrow or limited purposes.

In addition, we do not engage in trading activities involving non-exchange traded contracts.

Recently Issued Accounting Pronouncements

For a discussion of new accounting pronouncements, see Note 2 in the Notes to the Condensed Consolidated Financial Statements in Part I, Item 1, Unaudited Condensed Financial Statements, of this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The primary objective of our investment activities is to preserve our capital to fund operations and to facilitate business development activities. We also seek to maximize income from our investments without assuming significant interest rate risk, liquidity risk, or risk of default by investing in investment grade securities with maturities of four years or less. Our exposure to market risk is confined to investments in cash, cash equivalents, marketable securities, and long term marketable securities. As of September 30, 2021, we had unrestricted cash, cash equivalents, marketable securities, and long term marketable securities of
$849.3 million.

In connection with the 2023 Notes, we have separately entered into Convertible Note Hedge Transactions and Warrant Transactions to reduce the potential dilution of the Company’s common stock upon conversion of the 2023 Notes, and to partially offset the cost to purchase the Convertible Note Hedge Transactions, respectively.

Our cash and cash equivalents consist primarily of cash held at banks and investments in highly liquid financial instruments with an original maturity of three months or less. Our marketable securities as of September 30, 2021, which are reported at fair value, consist of investment grade corporate debt securities. We place all investments with governmental, industrial, or financial institutions whose debt is rated as investment grade. We generally hold these securities to maturities of one to four years. Because of the relatively short period that we hold our investments and because we generally hold these securities to maturity, we do not believe that a change in interest rates would have any significant impact on the realizable value of our investments. We do not have any currency or other derivative financial instruments other than outstanding warrants to purchase common stock and the convertible note hedges.

We may contract with clinical research organizations (CROs), investigational sites and contract manufacturing organizations (CMOs) globally. Currently, we have an ongoing trial for SPN-817 outside the U.S. We have CMOs outside of the

Table of Content s

U.S. who manufacture and supply certain of our clinical and commercial products and raw materials. We do not hedge our foreign currency exchange rate risk. Transactions denominated in currencies other than the U.S. dollar are recorded based on exchange rates at the time such transactions arise. As of September 30, 2021 and December 31, 2020, substantially all of our liabilities were denominated in the U.S. dollar. We do not believe that changes in foreign currency exchange rates over the nine months ended September 30, 2021 and 2020 had a significant impact on our consolidated results of operations.

Inflation generally affects us by increasing our cost of labor, cost of purchased goods, and the cost of services provided by our vendors. We do not believe that inflation and changing prices over the nine months ended September 30, 2021 and 2020 had a significant impact on our consolidated results of operations. However, in the future, inflation may have an effect on our consolidated results of operations.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures over financial reporting, as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed in the reports we file or submit under the Exchange Act has been appropriately recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Moreover, such information is accumulated and communicated to our management, including our CEO and CFO, to allow timely decisions regarding required disclosure.

We conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures over financial reporting as of September 30, 2021, the end of the period covered by this report. Based on that evaluation, under the supervision and with the participation of our management, including our CEO and CFO, we concluded that our disclosure controls and procedures were effective as of September 30, 2021.

Changes in Internal Control over Financial Reporting

On June 9, 2020, the Company completed the USWM Acquisition. As of June 30, 2021, the integration of the internal controls relating to the business acquired through the USWM Acquisition into our business has been completed. The business combination accounting for the USWM Acquisition was completed during the second quarter of 2021, and the acquired business will be included in our evaluation of the effectiveness of our internal control over financial reporting for fiscal year 2021.

In July 2021, the Company announced, effective August 13, 2021, the resignation of the former CFO. The current CFO was appointed by the Board of Directors effective August 23, 2021.

During the three months ended September 30, 2021, no changes occurred in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
