NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
1.                                    The Company and Basis of Presentation
Insmed is a global biopharmaceutical company on a mission to transform the lives of patients with serious and rare diseases. The Company's first commercial product, ARIKAYCE, is approved in the United States (US) as ARIKAYCE® (amikacin liposome inhalation suspension), in Europe as ARIKAYCE Liposomal 590 mg Nebuliser Dispersion and in Japan as ARIKAYCE inhalation 590mg (amikacin sulfate inhalation drug product). ARIKAYCE received accelerated approval in the US in September 2018 for the treatment of Mycobacterium avium complex (MAC) lung disease as part of a combination antibacterial drug regimen for adult patients with limited or no alternative treatment options in a refractory setting. In October 2020, the European Commission (EC) approved ARIKAYCE for the treatment of nontuberculous mycobacterial (NTM) lung infections caused by MAC in adults with limited treatment options who do not have cystic fibrosis (CF). In March 2021, Japan's Ministry of Health, Labour and Welfare (MHLW) approved ARIKAYCE for the treatment of patients with NTM lung disease caused by MAC who did not sufficiently respond to prior treatment with a multidrug regimen. NTM lung disease caused by MAC (which the Company refers to as MAC lung disease) is a rare and often chronic infection that can cause irreversible lung damage and can be fatal. The Company's clinical-stage pipeline includes brensocatib and treprostinil palmitil inhalation powder (TPIP). Brensocatib is a small molecule, oral, reversible inhibitor of dipeptidyl peptidase 1 (DPP1), which the Company is developing for the treatment of patients with bronchiectasis, CF and other neutrophil-mediated diseases, including chronic rhinosinusitis without nasal polyps (CRSsNP) and hidradenitis suppurativa (HS). TPIP is an inhaled formulation of the treprostinil prodrug treprostinil palmitil which may offer a differentiated product profile for pulmonary hypertension associated with interstitial lung disease (PH-ILD) and pulmonary arterial hypertension (PAH).
The Company was incorporated in the Commonwealth of Virginia on November 29, 1999 and its principal executive offices are located in Bridgewater, New Jersey. The Company has legal entities in the US, France, Germany, Ireland, Italy, the Netherlands, Switzerland, the United Kingdom (UK), and Japan.
The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain information and disclosures required by accounting principles generally accepted in the US for complete consolidated financial statements are not included herein. The unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2021.
     The results of operations of any interim period are not necessarily indicative of the results of operations for the full year. The unaudited interim consolidated financial information presented herein reflects all normal adjustments that are, in the opinion of management, necessary for a fair statement of the financial position, results of operations and cash flows for the periods presented. All intercompany transactions and balances have been eliminated in consolidation.
     The Company had $416.1 million in cash and cash equivalents and marketable securities totaling $148.6 million as of June 30, 2022 and reported a net loss of $190.3 million for the six months ended June 30, 2022. Historically, the Company has funded its operations through public offerings of equity securities and debt financings. The Company expects to continue to incur consolidated operating losses, including losses in its US and certain international entities, while funding research and development (R&D) activities for ARIKAYCE, brensocatib, TPIP and its other pipeline programs, and continuing and commencing pre-commercial, commercialization and regulatory activities for ARIKAYCE, and funding other general and administrative activities.
The Company expects its future cash requirements to be substantial, and the Company may need to raise additional capital to fund operations, including the Phase 3 ASPEN study, the continued commercialization of ARIKAYCE, the ARISE and ENCORE clinical trials related to ARIKAYCE, launch readiness activities for the potential launch of brensocatib, if approved, other clinical trials for brensocatib, TPIP, and its future product candidates, and to develop, acquire, in-license or co-promote other products or product candidates, including those that address orphan or rare diseases. The source, timing and availability of any future financing or other transaction will depend principally upon continued progress in the Company’s commercial, regulatory and development activities. Any equity or debt financing will also be contingent upon equity and debt market conditions and interest rates at the time. If the Company is unable to obtain sufficient additional funds when required, the Company may be forced to delay, restrict or eliminate all or a portion of its development programs or commercialization efforts. The Company believes it currently has sufficient funds to meet its financial needs for at least the next 12 months.
Risks and Uncertainties - There are many uncertainties regarding the novel coronavirus (COVID-19) pandemic, and the Company is closely monitoring the impact of the pandemic on all aspects of its business, including how the pandemic will impact its patients, employees, suppliers, vendors, business partners and distribution channels. While the pandemic did not materially affect the Company's financial results and business operations for the six months ended June 30, 2022, the Company is unable to predict the impact that COVID-19 will have on its financial position and operating results in future periods due to
8

Table of Contents
numerous uncertainties. The Company will continue to assess the evolving impact of the COVID-19 pandemic and will make adjustments to its operations as necessary.
2.                                      Summary of Significant Accounting Policies
The following are the required interim disclosure updates to the Company's significant accounting policies described in Note 2 of the notes to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2021:
     Fair Value Measurements - The Company categorizes its financial assets and liabilities measured and reported at fair value in the financial statements on a recurring basis based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are directly related to the amount of subjectivity associated with the inputs used to determine the fair value of financial assets and liabilities, are as follows:
Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.
Level 2 — Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the assets or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.
Level 3 — Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.
Each major category of financial assets and liabilities measured at fair value on a recurring basis is categorized based upon the lowest level of significant input to the valuations. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Financial instruments in Level 1 generally include US treasuries and mutual funds listed in active markets. The Company's cash and cash equivalents permit daily redemption and the fair values of these investments are based upon the quoted prices in active markets provided by the holding financial institutions.
The following table shows assets and liabilities that are measured at fair value on a recurring basis and their carrying value (in millions):

Deferred consideration$14.9 $— $14.9 $— 
Contingent consideration liabilities$75.7 $— $— $75.7 
The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each quarter. During the six months ended June 30, 2022, the Company purchased $99.7 million of additional marketable securities consisting of US Treasury Notes. There were no other transfers in or out of Level 1, Level 2 or Level 3 during the six months ended June 30, 2022.
As of June 30, 2022, the Company held $138.8 million and $9.8 million of current and non-current available-for-sale securities, respectively, net of an unrealized loss of $1.3 million recorded in accumulated other comprehensive income. Marketable securities maturing in one year or less are classified as current assets and marketable securities maturing in more
9

Table of Contents
than one year are classified as non-current assets. As of December 31, 2021, the Company held no securities that were in an unrealized gain or loss position.

The Company reviews the status of each security quarterly to determine whether an other-than-temporary impairment has occurred. In making its determination, the Company considers a number of factors, including: (1) the significance of the decline; (2) whether the security was rated below investment grade; (3) how long the security has been in an unrealized loss position; and (4) the Company's ability and intent to retain the investment for a sufficient period of time for it to recover. The Company has determined that there were no other-than-temporary impairments during the quarter ended June 30, 2022.
Deferred Consideration
The deferred consideration arose from the acquisitions of Motus Biosciences, Inc. (Motus) and AlgaeneX, Inc. (AlgaeneX) (the Business Acquisition) in August 2021 (Note 13). The Company is obligated to issue to Motus equityholders an aggregate of 184,433 shares of the Company’s common stock on each of the first, second and third anniversaries of the closing date, subject to certain reductions. A valuation of the deferred consideration is performed quarterly with gains and losses included within change in fair value of deferred and contingent consideration liabilities in the consolidated statements of comprehensive loss. As the deferred consideration is settled in shares, there is no discount rate applied in the fair value calculation.
The deferred consideration has been classified as a Level 2 recurring liability as its valuation utilizes an input, the Insmed share price on the valuation date, which is a directly observable input at the measurement date and for the duration of the liabilities' anticipated lives. Deferred consideration expected to be settled within twelve months or less is classified as a current liability and are included in accrued liabilities. As of June 30, 2022, the fair value of deferred consideration included in accrued liabilities was $3.5 million. Deferred consideration expected to be settled in more than twelve months is classified as a non-current liability and is included in other long-term liabilities. As of June 30, 2022, the fair value of deferred consideration included in other long-term liabilities was $7.3 million.
The following observable input was used in the valuation of the deferred consideration as of June 30, 2022:
Fair Value as of June 30, 2022 (in millions)
Observable InputInput Value
Deferred consideration$10.8
Insmed share price as of June 30, 2022
$19.72
Contingent Consideration
The contingent consideration liabilities arose from the Business Acquisition in August 2021 (Note 13). The contingent consideration liabilities consist of developmental and regulatory milestones, a priority review voucher milestone and net sales milestones. Upon the achievement of certain development and regulatory milestone events, the Company is obligated to issue to Motus equityholders up to 5,348,572 shares in the aggregate and AlgaeneX equityholders up to 368,867 shares in the aggregate. The fair value of the development and regulatory milestones are estimated utilizing a probability-adjusted approach. At June 30, 2022, the weighted average probability of success was 42%. The development and regulatory milestones will be settled in shares of the Company's common stock. As such, there is no discount rate applied in the fair value calculation.
If the Company were to receive a priority review voucher, the Company is obligated to pay to the Motus equityholders a portion of the value of the priority review voucher, subject to certain reductions. The potential payout will be either 50% of the after tax net proceeds received by the Company from a sale of the priority review voucher or 50% of the average of the sales prices for the last three publicly disclosed priority review voucher sales, less certain adjustments. The fair value of the priority review voucher milestone is estimated utilizing a probability-adjusted discounted cash flow approach. This obligation will be settled in cash.
The contingent consideration liabilities for net sales milestones were valued using an option pricing model with Monte Carlo simulation. As of June 30, 2022, the fair value of these net sales milestones were deemed immaterial to the overall fair value of the contingent consideration.
The contingent consideration liabilities have been classified as a Level 3 recurring liability as its valuation requires substantial judgment and estimation of factors that are not currently observable in the market. If different assumptions were used for the inputs to the valuation approach, the estimated fair value could be significantly different than the fair value the Company determined. Contingent consideration liabilities expected to be settled in more than twelve months are classified as a non-current liability. A valuation of the contingent consideration liabilities is performed quarterly with gains and losses included within change in fair value of contingent consideration liabilities in the consolidated statements of comprehensive loss.

Convertible Notes
The estimated fair value of the liability component of the Company's 0.75% convertible senior notes due 2028 (the 2028 Convertible Notes) (categorized as a Level 2 liability for fair value measurement purposes) as of June 30, 2022 was $496.0 million, determined using current market factors and the ability of the Company to obtain debt on comparable terms to the 2028 Convertible Notes. The $561.6 million carrying value of the 2028 Convertible Notes as of June 30, 2022 excludes the $13.4 million of the unamortized portion of the debt issuance costs.
The estimated fair value of the liability component of the Company's 1.75% convertible senior notes due 2025 (the 2025 Convertible Notes) (categorized as a Level 2 liability for fair value measurement purposes) as of June 30, 2022 was $208.3 million, determined using current market factors and the ability of the Company to obtain debt on comparable terms to the 2025 Convertible Notes. The $222.4 million carrying value of the 2025 Convertible Notes as of June 30, 2022 excludes the $2.6 million of the unamortized portion of the debt issuance costs.
Net Loss Per Share - Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted average number of common shares and other dilutive securities outstanding during the period. Potentially dilutive securities from stock options, restricted stock, restricted stock units (RSUs), performance stock units (PSUs) and convertible debt securities would be anti-dilutive as the Company incurred a net loss. Potentially dilutive common shares resulting from the assumed exercise of outstanding stock options and from the assumed conversion of the Company's convertible notes are determined based on the treasury stock method.

Concentration of Credit Risk—Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company places its cash equivalents with high credit-quality financial institutions and may invest its short-term investments in US treasury securities, mutual funds and government agency bonds. The Company has established guidelines relative to credit ratings and maturities that seek to maintain safety and liquidity.
The Company is exposed to risks associated with extending credit to customers related to the sale of products. The Company does not require collateral to secure amounts due from its customers. The Company uses an expected loss methodology to calculate allowances for trade receivables. The Company's measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The Company does not currently have a material allowance for collectible trade receivables. The following table presents the percentage of gross product revenue represented by the Company's three largest customers as of the six months ended June 30, 2022 and 2021.

operating results. A change in the relationship with the suppliers or manufacturers, or an adverse change in their business, could materially impact future operating results.
Revenue Recognition - In accordance with Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers, the Company recognizes revenue when a customer obtains control of promised goods or services, in an amount that reflects the consideration the Company expects to receive in exchange for the goods or services provided. To determine revenue recognition for arrangements within the scope of ASC 606, the Company performs the following five steps: (1) identify the contracts with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when or as the entity satisfies a performance obligation. At contract inception, the Company assesses the goods or services promised within each contract to determine which are performance obligations and to assess whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when or as the performance obligation is satisfied. For all contracts that fall into the scope of ASC 606, the Company has identified one performance obligation: the sale of ARIKAYCE to its customers. The Company has not incurred or capitalized any incremental costs associated with obtaining contracts with customers.
Product revenues, net consist of net sales of ARIKAYCE. The Company's customers in the US include specialty pharmacies and specialty distributors. In December 2020, the Company began recognizing product revenue from commercial sales of ARIKAYCE in Europe. In July 2021, the Company began recognizing product revenue from commercial sales of ARIKAYCE in Japan. Globally, product revenues are recognized once the Company performs and satisfies all five steps of the revenue recognition criteria mentioned above.
The following table presents a summary of the Company's product revenues, net, by geographic location for the three and six months ended June 30, 2022 and 2021 (in thousands):

Revenue is recorded at net selling price (transaction price), which includes estimates of variable consideration for which reserves are established for (a) customer credits, such as invoice discounts for prompt pay, (b) estimated government rebates, such as Medicaid and Medicare Part D reimbursements, and estimated managed care rebates, (c) estimated chargebacks, and (d) estimated costs of co-payment assistance. These reserves are based on the amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable (prompt pay discounts and chargebacks), prepaid expenses (co-payment assistance), or as a current liability (rebates). Where appropriate, these estimates take into consideration a range of possible outcomes which are probability-weighted for relevant factors such as the Company's historical experience, current contractual and statutory requirements, and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company's best estimates of the amount of consideration to which it is entitled based on the terms of the applicable contract. The amount of variable consideration included in the transaction price may be constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from the Company's estimates. If actual results in the future vary from estimates, the Company adjusts these estimates, which would affect net product revenue and earnings in the period such variances become known.
Customer credits: The Company's customers are offered various forms of consideration, including prompt payment discounts. The payment terms for sales to specialty pharmacies for prompt payment discounts are based on contractual rates agreed with the respective specialty pharmacies. The Company anticipates that its customers will earn these discounts and, therefore, deducts the full amount of these discounts from total gross product revenues at the time such revenues are recognized.
Rebates: The Company contracts with government agencies and managed care organizations, or collectively, third-party payors, so that ARIKAYCE will be eligible for purchase by, or partial or full reimbursement from, such third-party payors. The Company estimates the rebates it will provide to third-party payors and deducts these estimated amounts from total gross product revenues at the time the revenues are recognized. These reserves are recorded in the same period in which the revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability. The current liability is included in accrued liabilities on the consolidated balance sheets. The Company estimates the rebates that it will provide to third-party payors based upon (i) the Company's contracts with these third-party payors, (ii) the government
13

Table of Contents
mandated discounts applicable to government-funded programs, (iii) a range of possible outcomes that are probability-weighted for the estimated payor mix, and (iv) information obtained from the Company's specialty pharmacies.
Chargebacks: Chargebacks are discounts that occur when certain contracted customers, currently public health service institutions and federal government entities purchasing via the Federal Supply Schedule, purchase directly from the Company's specialty distributor. Contracted customers generally purchase the product at a discounted price and the specialty distributor, in turn, charges back to the Company the difference between the price the specialty distributor initially paid and the discounted price paid by the contracted customers. The Company estimates chargebacks provided to the specialty distributor and deducts these estimated amounts from gross product revenues, and from accounts receivable, at the time revenues are recognized.
Co-payment assistance: Patients who have commercial insurance and meet certain eligibility requirements may receive co-payment assistance. Based upon the terms of the program and information regarding programs provided for similar specialty pharmaceutical products, the Company estimates the average co-pay mitigation amounts and the percentage of patients that it expects to participate in the program in order to establish accruals for co-payment assistance. These reserves are recorded in the same period in which the related revenue is recognized, resulting in a reduction of product revenue. The Company adjusts its accruals for co-pay assistance based on actual redemption activity and estimates of future redemptions related to sales in the current period.
If any, or all, of the Company's actual experience varies from its estimates, the Company may need to adjust prior period accruals, affecting revenue in the period of adjustment.
The Company also recognizes revenue related to various early access programs (EAPs) in Europe, predominantly in France. EAPs are intended to make products available on a named patient basis before they are commercially available in accordance with local regulations.
Inventory and Cost of Product Revenues (excluding amortization of intangible assets) - Inventory is stated at the lower of cost and net realizable value. The Company began capitalizing inventory costs following US Food and Drug Administration (FDA) approval of ARIKAYCE in September 2018. Inventory is sold on a first-in, first-out (FIFO) basis. The Company periodically reviews inventory for expiry and obsolescence and, if necessary, writes down accordingly. If quality specifications are not met during the manufacturing process, such inventory is written off to cost of product revenues (excluding amortization of intangible assets) in the period identified.
Cost of product revenues (excluding amortization of intangible assets) consist primarily of direct and indirect costs related to the manufacturing of ARIKAYCE sold, including third-party manufacturing costs, packaging services, freight, and allocation of overhead costs, in addition to royalty expenses and revenue-based milestone payments. Cost is determined using a standard cost method, which approximates actual cost, and assumes a FIFO flow of goods.
Prior to FDA approval of ARIKAYCE, the Company expensed all inventory-related costs in the period incurred. Inventory used for clinical development purposes is expensed to R&D expense when consumed.
Business combinations and asset acquisitions - The Company evaluates acquisitions of assets and other similar transactions to assess whether or not the transaction should be accounted for as a business combination or asset acquisition by first applying a screen to determine if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If the screen is met, the transaction is accounted for as an asset acquisition. If the screen is not met, further determination is required as to whether or not the Company has acquired inputs and processes that have the ability to create outputs, which would meet the requirements of a business. If determined to be a business combination, the Company accounts for the transaction under the acquisition method of accounting as indicated in ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which requires the acquiring entity in a business combination to recognize the fair value of all assets acquired, liabilities assumed, and any non-controlling interest in the acquiree and establishes the acquisition date as the fair value measurement point. Accordingly, the Company recognizes assets acquired and liabilities assumed in business combinations, including contingent assets and liabilities, and non-controlling interest in the acquiree based on the fair value estimates as of the date of acquisition. In accordance with ASC 805, Business Combinations, the Company recognizes and measures goodwill as of the acquisition date, as the excess of the fair value of the consideration paid over the fair value of the identified net assets acquired.
The consideration for the Company’s business acquisitions may include future payments that are contingent upon the occurrence of a particular event or events. The obligations for such contingent consideration payments are recorded at fair value on the acquisition date. The contingent consideration obligations are then evaluated each reporting period. Changes in the fair value of contingent consideration, other than changes due to payments, are recognized as a gain or loss and recorded within change in the fair value of deferred and contingent consideration liabilities in the consolidated statements of comprehensive loss.
If determined to be an asset acquisition, the Company accounts for the transaction under ASC 805-50, which requires the acquiring entity in an asset acquisition to recognize assets acquired and liabilities assumed based on the cost to the acquiring
14

Table of Contents
entity on a relative fair value basis, which includes transaction costs in addition to consideration given. No gain or loss is recognized as of the date of acquisition unless the fair value of non-cash assets given as consideration differs from the assets’ carrying amounts on the acquiring entity’s books. Consideration transferred that is non-cash will be measured based on either the cost (which shall be measured based on the fair value of the consideration given) or the fair value of the assets acquired and liabilities assumed, whichever is more reliably measurable. Goodwill is not recognized in an asset acquisition and any excess consideration transferred over the fair value of the net assets acquired is allocated to the identifiable assets based on relative fair values.
Contingent consideration payments in asset acquisitions are recognized when the contingency is resolved and the consideration is paid or becomes payable (unless the contingent consideration meets the definition of a derivative, in which case the amount becomes part of the basis in the asset acquired). Upon recognition of the contingent consideration payment, the amount is included in the cost of the acquired asset or group of assets.
Indefinite-lived intangible assets - Indefinite-lived intangible assets consist of In Process Research & Development (IPR&D). IPR&D acquired directly in a transaction other than a business combination is capitalized if the projects will be further developed or have an alternative future use; otherwise they are expensed. The fair values of IPR&D project assets acquired in business combinations are capitalized. The Company generally utilizes the Multi-Period Excess Earning Method to determine the estimated fair value of the IPR&D assets acquired in a business combination. The projections used in this valuation approach are based on many factors, such as relevant market size, patent protection, and expected pricing and 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 written off, as appropriate. Intangible assets with indefinite lives, including IPR&D, are tested for impairment if impairment indicators arise and, at a minimum, annually. However, an entity is permitted to first assess qualitative factors to determine if a quantitative impairment test is necessary. Further testing is only required if the entity determines, based on the qualitative assessment, that it is more likely than not that an indefinite-lived intangible asset’s fair value is less than its carrying amount. The indefinite-lived intangible asset impairment test consists of a one-step analysis that compares the fair value of the intangible asset with its carrying amount. If the carrying amount of an intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. The Company considers many factors in evaluating whether the value of its intangible assets with indefinite lives may not be recoverable, including, but not limited to, expected growth rates, the cost of equity and debt capital, general economic conditions, the Company’s outlook and market performance of the Company’s industry and recent and forecasted financial performance. The Company performs a qualitative test for its indefinite-lived intangible assets annually as of October 1.
Finite-lived Intangible Assets - Finite-lived intangible assets are measured at their respective fair values on the date they were recorded and, with respect to the acquired ARIKAYCE R&D intangible asset, at the date of subsequent adjustments of fair value. The fair values assigned to the Company's intangible assets are based on reasonable estimates and assumptions given available facts and circumstances.
Impairment Assessment - The Company reviews the recoverability of its finite-lived intangible assets and long-lived assets for indicators of impairments. Events or circumstances that may require an impairment assessment include negative clinical trial results, a significant decrease in the market price of the asset, or a significant adverse change in legal factors or the manner in which the asset is used. If such indicators are present, the Company assesses the recoverability of affected assets by determining if the carrying value of such assets is less than the sum of the undiscounted future cash flows of the assets. If such assets are found to not be recoverable, the Company measures the amount of the impairment by comparing to the carrying value of the assets to the fair value of the assets. The Company determined that no indicators of impairment of finite-lived intangible assets or long-lived assets existed at June 30, 2022.
Goodwill - Goodwill represents the amount of consideration paid in excess of the fair value of net assets acquired as a result of the Company’s business acquisitions accounted for using the acquisition method of accounting. Goodwill is not amortized and is subject to impairment testing at a reporting unit level on an annual basis or when a triggering event occurs that may indicate the carrying value of the goodwill is impaired. The Company reassesses its reporting units as part of its annual segment review. An entity is permitted to first assess qualitative factors to determine if a quantitative impairment test is necessary. Further testing is only required if the entity determines, based on the qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. The Company will perform its next annual impairment testing for goodwill on October 1, 2022.
Leases - A lease is a contract, or part of a contract, that conveys the right to control the use of explicitly or implicitly identified property, plant or equipment in exchange for consideration. Control of an asset is conveyed to the Company if the Company obtains the right to obtain substantially all of the economic benefits of the asset or the right to direct the use of the asset. The Company recognizes right-of-use (ROU) assets and lease liabilities at the lease commencement date based on the present value of future, fixed lease payments over the term of the arrangement. ROU assets are amortized on a straight-line basis over the term of the lease or are amortized based on consumption, if this approach is more representative of the pattern in

which benefit is expected to be derived from the underlying asset. Lease liabilities accrete to yield and are reduced at the time when the lease payment is payable to the vendor. Variable lease payments are recognized at the time when the event giving rise to the payment occurs and are recognized in the consolidated statements of comprehensive loss in the same line item as expenses arising from fixed lease payments.
Leases are measured at present value using the rate implicit in the lease or, if the implicit rate is not determinable, the lessee's implicit borrowing rate. As the implicit rate is not typically available, the Company uses its implicit borrowing rate based on the information available at the lease commencement date to determine the present value of future lease payments. The implicit borrowing rate approximates the rate the Company would pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments.

Recently Adopted Accounting Pronouncements - In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also promote consistent application of and simplify US generally accepted accounting principles (GAAP) for other areas of Topic 740 by clarifying and amending the existing guidance. For public business entities, the guidance was effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2020. The Company adopted this guidance January 1, 2021. The adoption of the guidance did not have a material impact on the Company's consolidated financial statements and accompanying notes.
In August 2020, the FASB issued 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, to reduce the complexity associated with applying GAAP to certain financial instruments with characteristics of liabilities and equity. For convertible instruments, the number of accounting models for convertible debt instruments is reduced, which results in fewer embedded conversion features being separately recognized from the host contract as compared with current GAAP. Only convertible instruments that meet the definition of a derivative or are issued with substantial premiums will continue to be subject to the separation models. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost and a share of convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost, as long as no other features require bifurcation and recognition as derivatives. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021. The Company transitioned using the modified retrospective method. The impact of adopting ASU 2020-06 on January 1, 2022 resulted in an opening balance sheet adjustment increasing debt by $221.9 million, increasing issuance costs classified to debt by $6.1 million, decreasing the deferred tax liability by $1.4 million, and causing an increase to retained earnings of $50.2 million, with an offsetting reduction to additional paid-in-capital of $264.6 million, net of tax.
3.            Inventory
As of June 30, 2022 and December 31, 2021, the Company's inventory balance consists of the following (in thousands):

7.                                    Leases
The Company's lease portfolio consists primarily of office and laboratory space, manufacturing facilities, research equipment and fleet vehicles. All of the Company's leases are classified as operating leases, except for the Company's leases of its corporate headquarters and a research facility in San Diego, which are classified as finance leases. The terms of the Company's lease agreements that have commenced range from less than one year to ten years, ten months. In its assessment of the term of each such lease, the Company has not included any options to extend or terminate the lease due to the absence of economic incentives in its lease agreements. Leases that qualify for treatment as a short-term lease are expensed as incurred. These short-term leases are not material to the Company's financial position. Furthermore, the Company does not separate lease and non-lease components for all classes of underlying assets. The Company's leases do not contain residual value guarantees and it does not sublease any of its leased assets.
The Company outsources its manufacturing operations to CMOs. Upon review of the agreements with its CMOs, the Company determined that these contracts contain embedded leases for dedicated manufacturing facilities. The Company obtains substantially all of the economic benefits from the use of the manufacturing facilities, the Company has the right to direct how and for what purpose the facility is used throughout the period of use, and the supplier does not have the right to change the operating instructions of the facility. The operating lease right-of-use assets and corresponding lease liabilities associated with the manufacturing facilities is the sum of the minimum guarantees over the life of the production contracts.
The Company also records variable consideration for variable lease payments in excess of fixed fees or minimum guarantees. Variable consideration related to the Company's leasing arrangements was $1.5 million and $0.2 million for the three months ended June 30, 2022 and 2021, respectively, and $1.6 million and $0.3 million for the six months ended June 30, 2022 and 2021, respectively. Variable costs related to CMO manufacturing agreements are direct costs related to the manufacturing of ARIKAYCE and are capitalized within inventory in the Company's consolidated balance sheet, while the variable costs related to other leasing arrangements, not related to the manufacturing of ARIKAYCE, have been classified within operating expenses in the Company's consolidated statements of comprehensive loss.

Holders may convert their 2025 Convertible Notes prior to October 15, 2024 or their 2028 Convertible Notes prior to March 1, 2028, only under the following circumstances, subject to the conditions set forth in the applicable indenture: (i) during the five business day period immediately after any five consecutive trading day period (the measurement period) in which the trading price per $1,000 principal amount of the applicable series of convertible notes, as determined following a request by a holder of such convertible notes, for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the common stock and the conversion rate on such trading day, (ii) the Company elects to distribute to all or substantially all holders of the common stock (a) any rights, options or warrants (other than in connection with a stockholder rights plan for so long as the rights issued under such plan have not detached from the associated shares of common stock) entitling them, for a period of not more than 45 days from the declaration date for such distribution, to subscribe for or purchase shares of common stock at a price per share that is less than the average of the last reported sale prices of the common stock for the 10 consecutive trading day period ending on, and including, the trading day immediately preceding the declaration date for such distribution, or (b) the Company's assets, debt securities or rights to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the board of directors, exceeding 10% of the last reported sale price of the common stock on the trading day immediately preceding the declaration date for such distribution, (iii) if a transaction or event that constitutes a fundamental change or a make-whole fundamental change occurs, or if the Company is a party to (a) a consolidation, merger, combination, statutory or binding share exchange or similar transaction, pursuant to which the common stock would be converted into, or exchanged for, cash, securities or other property or assets, or (b) any sale, conveyance, lease or other transfer or similar transaction in one transaction or a series of transactions of all or substantially all of the consolidated assets of the Company and its subsidiaries, taken as a whole, all or any portion of the applicable series of convertible notes may be surrendered by a holder for conversion at any time from or after the date that is 30 scheduled trading days prior to the anticipated effective date of the transaction, (iv) if during any calendar quarter commencing after the calendar quarter ending on March 31, 2018 or June 30, 2021 for the 2025 Convertible Notes and the 2028 Convertible Notes, respectively (and only during such calendar quarter), the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the

immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day, or (v) if the Company sends a notice of redemption, a holder may surrender all or any portion of its convertible notes to which the notice of redemption relates for conversion at any time on or after the date the applicable notice of redemption was sent until the close of business on (a) the second business day immediately preceding the related redemption date or (b) if the Company fails to pay the redemption price on the redemption date as specified in such notice of redemption, such later date on which the redemption price is paid. To date, there have not been any holder-initiated redemption requests of either series of convertible notes.

10.                                Stock-Based Compensation
The Company's current equity compensation plan, the Insmed Incorporated 2019 Incentive Plan (as amended, the 2019 Incentive Plan), was approved by shareholders at the Company's Annual Meeting of Shareholders in May 2019. The 2019 Incentive Plan is administered by the Compensation Committee of the Board of Directors of the Company. Under the terms of the 2019 Incentive Plan, the Company is authorized to grant a variety of incentive awards based on its common stock, including stock options (both incentive stock options and non-qualified stock options), RSUs, performance options/shares and other stock awards to eligible employees and non-employee directors. On May 16, 2019, upon the approval of the 2019 Incentive Plan by shareholders, 3,500,000 shares were authorized for issuance thereunder, plus any shares subject to then-outstanding awards under the Company's 2017 Incentive Plan, the 2015 Incentive Plan and the 2013 Incentive Plan that subsequently were canceled, terminated unearned, expired, were forfeited, lapsed for any reason or were settled in cash without the delivery of shares. On May 12, 2020, at the Company's 2020 Annual Meeting of Shareholders, the Company's shareholders approved an amendment of the 2019 Incentive Plan providing for the issuance of an additional 4,500,000 shares under the plan. On May 12, 2021, at the Company's 2021 Annual Meeting of Shareholders, the Company's shareholders approved the second amendment to the 2019 Incentive Plan providing for the issuance of an additional 2,750,000 shares under the plan. On May 11, 2022, at the Company's 2022 Annual Meeting of Shareholders, the Company's shareholders approved the third amendment to the 2019 Incentive Plan, providing for the issuance of an additional 3,000,000 shares under the plan. As of June 30, 2022, 2,145,104 shares remain available for future issuance under the 2019 Incentive Plan. The 2019 Incentive Plan will terminate on May 16, 2029 unless it is extended or terminated earlier pursuant to its terms. In addition, from time to time, the Company makes inducement grants of stock options to new hires, which awards are made pursuant to the Nasdaq's inducement grant exception to the shareholder approval requirement for grants of equity compensation. During the six months ended June 30, 2022, the Company granted inducement stock options covering 471,790 shares of the Company's common stock to new employees.
On May 15, 2018, the 2018 Employee Stock Purchase Plan (2018 ESPP) was approved by shareholders at the Company's 2018 Annual Meeting of Shareholders. The Company has reserved the following for issuance under the 2018 ESPP: (i) 1,000,000 shares of common stock, plus (ii) commencing on January 1, 2019 and ending on December 31, 2023, an additional number of shares to be added on the first day of each calendar year equal to the lesser of (A) 1,200,000 shares of common stock, (B) 2% of the number of outstanding shares of common stock on such date and (C) an amount determined by the administrator.
Stock Options — As of June 30, 2022, there was $122.5 million of unrecognized compensation expense related to unvested stock options.
From time to time, the Company has granted performance-conditioned options to certain of its employees. Vesting of these options is subject to the Company achieving certain performance criteria established at the date of grant and the grantees

fulfilling a service condition (continued employment). As of June 30, 2022, the Company had performance-conditioned options totaling 114,780 shares outstanding which had not yet met the recognition criteria.
Restricted Stock Units — As of June 30, 2022, there was $32.5 million of unrecognized compensation expense related to unvested RSU awards.
Performance Stock UnitsIn January 2022, the Company issued 271,612 PSUs. For these PSUs, there are two performance conditions, a service condition, and a market condition. The performance conditions are the issuance of a press release announcing certain top-line results from a clinical trial and the acceptance of a new drug application (NDA) by the FDA for brensocatib. The service condition is continuous employment with the Company through the later of the third anniversary of the grant date of the PSU award and the date an NDA for brensocatib is accepted by the FDA. The potential payout of the awards ranges from 0% to 250% of the target, dependent on a market condition that is based on the Company's total shareholder return compared to a defined peer group. Due to the multiple vesting conditions, uncertain timing and variable payout of these PSUs, a Monte Carlo simulation was performed to determine the fair value of the awards. Compensation cost will be recognized on the date the performance conditions become probable, with an initial recording of the cumulative expense that would have been recognized if the PSU expense had been recognized on a straight-line basis since the date of grant. The remaining unamortized fair value of the awards will then be expensed prospectively on a straight-line basis over the remaining service period. Since the market condition is reflected in the grant-date fair value and is not a condition for the award to vest, it does not impact the requisite service period. The volatility, risk-free interest rate and weighted-average grant date fair value of the PSUs granted are 65.4%, 1.03% and $39.12, respectively. Any forfeitures that occur after compensation cost recognition commences will result in the cumulative reversal of expense in the period in which the forfeiture occurs. As of June 30, 2022, there was $10.5 million of unrecognized compensation expense related to unvested PSU awards, which assumes a payout of 100% of the target.
The following table summarizes the aggregate stock-based compensation expense recorded in the consolidated statements of comprehensive loss related to stock options and RSUs during the three and six months ended June 30, 2022 and 2021, respectively (in millions): 
 Three Months Ended June 30,Six Months Ended June 30,
 2022202120222021
Research and development$6.7 $4.4 $12.3 $8.1 
Selling, general and administrative7.6 7.4 14.8 14.2 
Total$14.3 $11.8 $27.1 $22.3 
There was no stock-based compensation expense recorded in the consolidated statements of comprehensive loss related to PSUs during the three and six months ended June 30, 2022, as the performance conditions associated with the PSU awards were not probable as of June 30, 2022.
11.                                 Income Taxes
The Company recorded a provision for income taxes of $0.5 million and $0.6 million for the three months ended June 30, 2022 and 2021, respectively, and $0.9 million and $0.9 million for the six months ended June 30, 2022 and 2021, respectively. The provisions are primarily a result of certain of the Company's international subsidiaries, which had taxable income during the periods. Additionally, the Company is impacted by certain state taxes which effectively impose income tax on modified gross revenues. In jurisdictions where the Company has net losses, there was a full valuation allowance recorded against the Company's deferred tax assets and therefore no tax benefit was recorded.
The Company is subject to US federal and state income taxes and the statute of limitations for tax audit is open for the Company's federal tax returns for the years ended 2018 and later, and is generally open for certain states for the years 2017 and later. The Company has incurred net operating losses since inception, except for the year ended December 31, 2009. Such loss carryforwards would be subject to audit in any tax year in which those losses are utilized, notwithstanding the year of origin. As of June 30, 2022 and December 31, 2021, the Company had recorded reserves for unrecognized income tax benefits against certain deferred tax assets in the US. However, given the Company’s valuation allowance position, these reserves do not have an impact on the balance sheet as of June 30, 2022 and December 31, 2021 or the consolidated statements of comprehensive loss for the three and six months ended June 30, 2022 and 2021. The Company has not recorded any accrued interest or penalties related to uncertain tax positions. The Company does not anticipate any material changes in the amount of unrecognized tax positions over the next 12 months.
12.                               Commitments and Contingencies
Rent expense charged to operations was $1.9 million and $1.1 million for the three months ended June 30, 2022 and 2021, respectively, and $3.9 million and $2.3 million for the six months ended June 30, 2022 and 2021, respectively.

Legal Proceedings
From time to time, the Company is a party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. While the outcomes of these matters are uncertain, management does not expect that the ultimate costs to resolve these matters will have a material adverse effect on the Company's consolidated financial position, results of operations or cash flows.
13.     Business Acquisition
On August 4, 2021, the Company acquired all of the equity interests of Motus and AlgaeneX, each a privately held, preclinical stage company. In connection with the closing of the Company’s acquisition of Motus, the Company issued an aggregate of 2,889,367 shares of the Company’s common stock, following certain closing-related reductions, to Motus’s former stockholders and option holders and certain individuals who are entitled to receive a portion of the acquisition consideration (collectively, Motus equityholders), subject to certain adjustments. The Company is obligated to issue to Motus equityholders an aggregate of 184,433 shares of the Company’s common stock on each of the first, second and third anniversaries of the closing date and up to 5,348,572 shares in the aggregate upon the achievement of certain development and regulatory milestone events, and to pay to the Motus equityholders an aggregate of $35 million upon the achievement of certain net sales-based milestones and a portion of the value of a priority review voucher (to the extent issued to the Company), in each case, subject to certain reductions.
At the closing of the Company’s acquisition of AlgaeneX, the Company paid $1.5 million in cash to AlgaeneX’s former stockholders and certain individuals who are entitled to receive a portion of the acquisition consideration (collectively, the AlgaeneX equityholders). The Company is obligated to issue to AlgaeneX’s equityholders an aggregate of 368,867 shares of the Company’s common stock upon the achievement of a development milestone event and pay to AlgaeneX equityholders a mid-single digits licensing fee on certain future payments received by the Company in licensing transactions for AlgaeneX’s manufacturing technology, in each case, subject to certain reductions.
The shares of the Company’s common stock issued to the Motus equityholders and the AlgaeneX equityholders were issued, and the shares issuable in the future will be issued, pursuant to Section 4(a)(2) of the Securities Act of 1933, and the numbers of such issued and issuable shares was calculated based on a per share value of $27.11, which is the weighted average price per share of the Company's common stock preceding the closing of the Business Acquisition for the 45 consecutive trading day period beginning on May 24, 2021. The Company will not receive any proceeds from the issuance of common stock to the Motus equityholders or the AlgaeneX equityholders.
The Company evaluated the Business Acquisition under ASC 805 and ASU 2017-01. The Company concluded that substantially all of the fair value of the gross assets acquired is not concentrated in a single identifiable asset or a group of similar identifiable assets. The transaction does not pass the screen test and thus management performed a full assessment to determine if the acquired entities met the definition of a business. For the full assessment, management considered whether it has acquired (a) inputs, (b) substantive processes, and (c) outputs. Under ASC 805, to be considered a business, a set of activities and assets is required to have only the first two of the three elements, which together are or will be used in the future to create outputs. Management determined that the acquired entities met the definition of a business since the Company acquired inputs and substantive processes capable of producing outputs.
Therefore, the transaction has been accounted for under the acquisition method of accounting. Under the acquisition method, the total purchase price of the acquisition is allocated to the net tangible and identifiable intangible assets acquired and liabilities assumed based on the fair values as of the date of the acquisition. The fair value of the consideration totaled approximately $165.5 million. The results of Motus's and AlgaeneX's operations have been included in the Company's consolidated statements of comprehensive loss beginning on the acquisition date.
The fair value of IPR&D was capitalized as of the acquisition date and accounted for as indefinite-lived intangible assets until completion or disposition of the assets or abandonment of the associated research and development efforts. Upon successful completion of the development efforts, the useful lives of the IPR&D assets will be determined based on the anticipated period of regulatory exclusivity and will be amortized within operating expenses. Until that time, the IPR&D assets will be subject to impairment testing and will not be amortized. The goodwill recorded related to the acquisition is the excess of the fair value of the consideration transferred by the acquirer over the fair value of the net identifiable assets acquired and liabilities assumed at the date of acquisition. The goodwill recorded is not deductible for tax purposes.

OVERVIEW
     We are a global biopharmaceutical company on a mission to transform the lives of patients with serious and rare diseases. Our first commercial product, ARIKAYCE, is approved in the US as ARIKAYCE® (amikacin liposome inhalation suspension), in Europe as ARIKAYCE Liposomal 590 mg Nebuliser Dispersion and in Japan as ARIKAYCE inhalation 590mg (amikacin sulfate inhalation drug product). ARIKAYCE received accelerated approval in the US in September 2018 for the treatment of MAC lung disease as part of a combination antibacterial drug regimen for adult patients with limited or no alternative treatment options in a refractory setting. In October 2020, the EC approved ARIKAYCE for the treatment of NTM lung infections caused by MAC in adults with limited treatment options who do not have CF. In March 2021, Japan's MHLW approved ARIKAYCE for the treatment of patients with NTM lung disease caused by MAC who did not sufficiently respond to

prior treatment with a multidrug regimen. NTM lung disease caused by MAC (which we refer to as MAC lung disease) is a rare and often chronic infection that can cause irreversible lung damage and can be fatal.
Our clinical-stage pipeline includes brensocatib and TPIP. Brensocatib is a small molecule, oral, reversible inhibitor of DPP1, which we are developing for the treatment of patients with bronchiectasis, CF and other neutrophil-mediated diseases, including CRSsNP and HS. TPIP is an inhaled formulation of the treprostinil prodrug treprostinil palmitil which may offer a differentiated product profile for PH-ILD and PAH.
The table below summarizes the current status and anticipated milestones for ARIKAYCE and our product candidates brensocatib and TPIP.
Principal Product/Product Candidate Status Next Expected Milestones
ARIKAYCE for MAC lung disease 
• We continue to focus on the commercialization of ARIKAYCE. We commenced commercial shipments of ARIKAYCE in the US in October 2018, in Europe in November 2020, and in Japan in July 2021.

• In December 2020, we commenced the post-marketing confirmatory frontline clinical trial program for ARIKAYCE in patients with MAC lung disease, consisting of the ARISE trial and the ENCORE trial. We are currently enrolling patients for these trials and are running these global studies in parallel.
 
• We will continue to advance the post-marketing confirmatory, frontline clinical trial program for ARIKAYCE. In ARISE, we anticipate completing enrollment by the end of 2022 and sharing data during 2023. In ENCORE, we anticipate completing enrollment by the end of 2023.
Brensocatib (oral reversible inhibitor of DPP1) for bronchiectasis and other neutrophil-mediated diseases

 
• In June 2020, we announced full results from our global, randomized, double-blind placebo-controlled Phase 2 WILLOW study, which were published online in the New England Journal of Medicine in September 2020.

• In December 2020, we commenced a Phase 3 trial (the ASPEN trial) through which we will seek to confirm the positive results seen in the WILLOW study. We are currently enrolling patients globally for this trial.
 
• We will continue to advance the ASPEN trial and anticipate completing enrollment in the first quarter of 2023.

• We are advancing a clinical development program for brensocatib in CF. The Phase 2 pharmacokinetics/pharmacodynamics multiple-dose study is underway, and we anticipate having results from the CF transmembrane conductance regulator (CFTR) arm of the study by the end of 2022.

• We plan to explore the potential of brensocatib in additional neutrophil-mediated diseases, including CRSsNP and HS.
TPIP (dry-powder inhalation formulation of a treprostinil prodrug) for PH-ILD and PAH

 
• In February 2021, we announced topline results from the Phase 1 study of TPIP in healthy volunteers. Data from the study supports continued development into Phase 2 with once-daily dosing.

• We are advancing the development of TPIP in both PH-ILD and PAH.

• We currently have two parallel Phase 2 studies ongoing, both with a 16-week treatment period: a study in patients with PH-ILD to assess safety and tolerability; and a study in PAH patients to evaluate the effect of TPIP on pulmonary vascular resistance (PVR) and six-minute walk distance.
 
• We will continue to advance our Phase 2 development work in both PH-ILD and PAH.


Our earlier-stage pipeline includes preclinical compounds that we are evaluating in multiple rare diseases with unmet medical need. To complement our internal research and development, we actively evaluate in-licensing and acquisition opportunities for a broad range of rare diseases.

Our Strategy
Our strategy focuses on the needs of patients with rare diseases. We secured approval for ARIKAYCE in the US as ARIKAYCE® (amikacin liposome inhalation suspension), in Europe as ARIKAYCE Liposomal 590 mg Nebuliser Dispersion and in Japan as ARIKAYCE inhalation 590mg (amikacin sulfate inhalation drug product). We are not aware of any other approved inhaled therapies specifically indicated to treat MAC lung disease in North America, Europe or Japan. We believe that ARIKAYCE has the potential to prove beneficial in other patients with MAC. Our product candidates are brensocatib, our Phase 3 product candidate which we are developing for patients with bronchiectasis, CF and other neutrophil-mediated diseases, and TPIP, our product candidate that may offer a differentiated product profile for patients with PH-ILD and PAH. We are also advancing earlier-stage programs in other rare disorders.
Our current priorities are as follows:
Continue our efforts to ensure the successful commercialization and expansion of ARIKAYCE globally;
Advance our Phase 3 ASPEN trial for brensocatib in patients with bronchiectasis;
Develop and validate a PRO tool for NTM lung disease to be used in, among other trials, the ENCORE trial required for the full US approval of ARIKAYCE by the FDA in patients with MAC lung disease;
Ensure our product supply chain will support the global commercialization and potential future lifecycle management programs of ARIKAYCE;
Maintain or obtain determinations of coverage and reimbursement in the US, Europe and Japan for ARIKAYCE from governmental and other third-party payors;
Support further research and lifecycle management strategies for ARIKAYCE, including the potential use of ARIKAYCE as part of a frontline, multi-drug regimen;
Advance the brensocatib program in CF and other neutrophil mediated diseases, such as CRSsNP and HS;
Advance the Phase 2 TPIP development programs;
Generate preclinical findings from our earlier-stage programs and advance translational medicine; and
Expand our pipeline through corporate development.
 ARIKAYCE for Patients with MAC Lung Disease
ARIKAYCE is our first approved product. ARIKAYCE received accelerated approval in the US in September 2018 for the treatment of refractory MAC lung disease as part of a combination antibacterial drug regimen for adult patients with limited or no alternative treatment options. In October 2020, ARIKAYCE received approval in Europe for the treatment of NTM lung infections caused by MAC in adults with limited treatment options who do not have CF. In March 2021, ARIKAYCE received approval in Japan for the treatment of patients with NTM lung disease caused by MAC who did not sufficiently respond to prior treatment with a multidrug regimen. MAC lung disease is a rare and often chronic infection that can cause irreversible lung damage and can be fatal. Amikacin solution for parenteral administration is an established drug that has activity against a variety of NTM; however, its use is limited by the need to administer it intravenously and by toxicity to hearing, balance, and kidney function. Unlike amikacin solution for intravenous administration, our proprietary Pulmovance™ technology uses charge-neutral liposomes to deliver amikacin directly to the lungs where liposomal amikacin is taken up by the lung macrophages where the MAC infection resides. This technology also prolongs the release of amikacin in the lungs, while minimizing systemic exposure, thereby offering the potential for decreased systemic toxicities. ARIKAYCE's ability to deliver high levels of amikacin directly to the lung and sites of MAC infection via the use of our Pulmovance technology distinguishes it from intravenous amikacin. ARIKAYCE is administered once-daily using Lamira, an inhalation device developed and manufactured by PARI. Lamira is a portable nebulizer that enables aerosolization of liquid medications via a vibrating, perforated membrane, and was designed specifically for ARIKAYCE delivery.
The FDA has designated ARIKAYCE as an orphan drug and a Qualified Infectious Disease Product (QIDP) for NTM lung disease. Orphan designated drugs are eligible for seven years of exclusivity for the orphan indication. QIDP designation provides an additional five years of exclusivity for the designated indication. The FDA granted a total of 12 years of exclusivity in the indication for which ARIKAYCE was approved.
ARIKAYCE also has been included in the international treatment guidelines for NTM lung disease. The evidence-based guidelines, issued by the American Thoracic Society (ATS), European Respiratory Society (ERS), European Society of Clinical Microbiology and Infectious Diseases (ESCMID), and Infectious Diseases Society of America (IDSA), now strongly recommend the use of ARIKAYCE for MAC lung disease as part of a combination antibacterial drug regimen for adult patients with limited or no alternative treatment options who have failed to convert to a negative sputum culture after at least six months of treatment.

In October 2020, the FDA approved an sNDA for ARIKAYCE, adding important efficacy data regarding the durability and sustainability of culture conversion to the ARIKAYCE label. The data, which are from the Phase 3 CONVERT study of ARIKAYCE, demonstrate that the addition of ARIKAYCE to guideline-based therapy (GBT) was associated with sustained culture conversion through the end of treatment as well as durable culture conversion three months post-treatment compared with GBT alone.
Accelerated Approval
In March 2018, we submitted an NDA for ARIKAYCE to the FDA to request accelerated approval. Accelerated approval allows drugs that (i) are being developed to treat a serious or life-threatening disease or condition and (ii) provide a meaningful therapeutic benefit over existing treatments to be approved substantially based on an intermediate endpoint or a surrogate endpoint that is reasonably likely to predict clinical benefit, rather than a clinical endpoint such as survival or irreversible morbidity. In September 2018, the FDA granted accelerated approval for ARIKAYCE under the Limited Population Pathway for Antibacterial and Antifungal Drugs (LPAD) for the treatment of refractory MAC lung disease as part of a combination antibacterial drug regimen for adult patients with limited or no alternative treatment options via the accelerated approval pathway. LPAD, which was enacted as part of the 21st Century Cures Act, serves to advance the development of new antibacterial drugs to treat serious or life-threatening infections in limited populations of patients with unmet needs. As required for drugs approved under the LPAD pathway, labeling for ARIKAYCE includes certain statements to convey that the drug has been shown to be safe and effective only for use in a limited population.
As a condition of accelerated approval, we must conduct a post-marketing confirmatory clinical trial. In December 2020, we commenced the post-marketing confirmatory frontline clinical trial program for ARIKAYCE in patients with MAC lung disease. The frontline clinical trial program consists of the ARISE trial, an interventional study designed to validate cross-sectional and longitudinal characteristics of a PRO tool in MAC lung disease, and the ENCORE trial, designed to establish the clinical benefits and evaluate the safety of ARIKAYCE in patients with newly diagnosed MAC lung disease using the PRO tool validated in the ARISE trial. We are running these global studies in parallel and approximately 200 sites are expected to be initiated for these clinical trials. The frontline clinical program is intended to fulfill the FDA’s post-marketing requirement to allow for full approval of ARIKAYCE by the FDA, and verification and description of clinical benefit in the ENCORE trial will be necessary for full approval of ARIKAYCE.
Regulatory Pathway Outside of the US
In October 2020, the EC granted marketing authorization for ARIKAYCE for the treatment of NTM lung infections caused by MAC in adults with limited treatment options who do not have CF. We have launched ARIKAYCE in Germany, the Netherlands, Wales, and Scotland, and plan to launch in other European Union (EU) countries and the UK, subject to local reimbursement processes. Effective September 1, 2022, patient supply of ARIKAYCE in Germany will be enabled by import from other EU countries. We have worked with the German National Association of Statutory Health Insurance Funds (GKV-SV) towards an agreement on the price of ARIKAYCE that would allow us effectively to serve the needs of patients in Germany; however, to date, we have been unable to reach an agreement. Ensuring an uninterrupted supply of medicine for patients in Germany is our top priority, and we are working to ensure that physicians and pharmacists have the information they need to obtain ARIKAYCE for their patients through the importation pathway. Discussions remain ongoing with the GKV-SV with the goal of reaching an agreement and re-initiating direct access to ARIKAYCE.
In March 2021, Japan's MHLW approved ARIKAYCE for the treatment of patients with NTM lung disease caused by MAC who did not sufficiently respond to prior treatment with a multidrug regimen. In July 2021, we launched ARIKAYCE in Japan.
Further Research and Lifecycle Management
We are currently exploring and supporting research and lifecycle management programs for ARIKAYCE beyond treatment of refractory MAC lung disease as part of a combination antibacterial regimen for adult patients who have limited or no treatment options. As noted above, we will continue to advance the post-marketing confirmatory, frontline clinical trial program for ARIKAYCE, through the ARISE and ENCORE trials, which are intended to fulfill the FDA's post-marketing requirement to allow for the full approval of ARIKAYCE in the US. We believe these studies will support the use of ARIKAYCE as a frontline treatment for patients with MAC lung disease.

Table of Contents
The ARISE trial is a randomized, double-blind, placebo-controlled Phase 3b study in adult patients with newly diagnosed MAC lung disease that aims to generate evidence demonstrating the domain specification, reliability, validity, and responsiveness of PRO-based scores, including a respiratory symptom score. Patients will be randomized 1:1 to receive ARIKAYCE plus background regimen or placebo plus background regimen once daily for six months. Patients will then discontinue all study treatments and remain in the trial for one month for the continued assessment of PRO endpoints. The study is currently enrolling patients and is expected to enroll approximately 100 patients. We anticipate completing enrollment by the end of 2022. We anticipate sharing data on the reliability and reproducibility of the respiratory score used in the PRO in the first half of 2023 and we anticipate sharing responsivity, culture conversion, and safety and tolerability data in the second half of 2023.
The ENCORE trial is a randomized, double-blind, placebo-controlled Phase 3b study to evaluate the efficacy and safety of an ARIKAYCE-based regimen in patients with newly diagnosed MAC lung disease. Patients will be randomized 1:1 to receive ARIKAYCE plus background regimen or placebo plus background regimen once daily for 12 months. Patients will then discontinue all study treatments and remain in the trial for three months for the assessment of durability of culture conversion. The primary endpoint is change from baseline to Month 13 in respiratory symptom score. The key secondary endpoint is the proportion of subjects achieving durable culture conversion at Month 15. The study is currently enrolling patients and is expected to enroll approximately 250 patients. We anticipate completing enrollment by the end of 2023.
We initiated the frontline clinical trial program of ARIKAYCE in December 2020 and are running the ARISE and ENCORE trials in parallel in approximately 200 sites.
Subsequent lifecycle management studies could also potentially enable us to reach more patients. These initiatives include investigator-initiated studies, which are clinical studies initiated and sponsored by physicians or research institutions with funding from us and may also include new clinical studies sponsored by us.
Product Pipeline
Brensocatib
Brensocatib is a small molecule, oral, reversible inhibitor of DPP1, which we licensed from AstraZeneca in October 2016. DPP1 is an enzyme responsible for activating neutrophil serine proteases (NSPs) in neutrophils when they are formed in the bone marrow. Neutrophils are the most common type of white blood cell and play an essential role in pathogen destruction and inflammatory mediation. Neutrophils contain the NSPs (including neutrophil elastase, proteinase 3, and cathepsin G) that have been implicated in a variety of inflammatory diseases. In chronic inflammatory lung diseases, neutrophils accumulate in the airways and result in excessive active NSPs that cause lung destruction and inflammation. Brensocatib may decrease the damaging effects of inflammatory diseases such as bronchiectasis by inhibiting DPP1 and its activation of NSPs.
Based on the positive results of the WILLOW study discussed below, in December 2020 we commenced our Phase 3 trial, ASPEN, which will investigate brensocatib in bronchiectasis. ASPEN is a global, randomized, double-blind, placebo-controlled Phase 3 study to assess the efficacy, safety, and tolerability of brensocatib in patients with bronchiectasis. Patients with bronchiectasis due to CF may not be enrolled in the study. Patients will be randomized to receive brensocatib 10 mg, brensocatib 25 mg, or placebo once daily for 52 weeks. The primary endpoint is the rate of pulmonary exacerbations over the 52-week treatment period. Secondary endpoints include time to first pulmonary exacerbation, percentage of subjects who remain pulmonary exacerbation-free, change from baseline in post-bronchodilator FEV1, rate of severe pulmonary exacerbations, change from baseline in the Bronchiectasis (QOL-B) Respiratory Symptoms Domain Score, and incidence and severity of treatment-emergent adverse events (AEs). This study is currently enrolling patients and is expected to enroll approximately 1,620 patients (540 in each arm) at approximately 460 sites in 40 countries. We anticipate completing enrollment in the first quarter of 2023.
In March 2020, AstraZeneca exercised its first option pursuant to our October 2016 license agreement under which AstraZeneca can advance clinical development of brensocatib in the indications of chronic obstructive pulmonary disease (COPD) or asthma. Under the terms of the agreement, upon exercise of this option, AstraZeneca is solely responsible for all aspects of the development of brensocatib up to and including Phase 2b clinical trials in COPD or asthma. The agreement also includes a second and final option which, if exercised, would permit AstraZeneca to further develop brensocatib beyond Phase 2b clinical trials upon reaching agreement on commercial terms satisfactory to each party for the further development and commercialization of brensocatib in COPD or asthma. We retain full development and commercialization rights for brensocatib in all other indications and geographies.
In June 2020, the FDA granted breakthrough therapy designation for brensocatib for the treatment of adult patients with non-cystic fibrosis bronchiectasis (NCFBE) for reducing exacerbations. The FDA's breakthrough therapy designation is designed to expedite the development and review of therapies that are intended to treat serious or life-threatening diseases and for which preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy. The benefits of breakthrough therapy designation include more frequent communication and meetings with FDA,

eligibility for rolling and priority review, intensive guidance on an efficient drug development program, and organizational commitment from the FDA involving senior managers. In November 2020, brensocatib was granted access to the PRIME scheme from the European Medicines Agency (EMA) for patients with NCFBE.
In October 2021, the EMA’s Paediatric Committee approved the brensocatib Pediatric Investigational Plan for the treatment of patients with NCFBE. Subsequently, the ASPEN trial will now include 40 adolescent patients between ages 12 to 17, which will fulfill the pediatric study requirements to support marketing applications in this patient population in the US, Europe and Japan.
The WILLOW Study
The WILLOW study was a randomized, double-blind, placebo-controlled, parallel-group, multi-center, multi-national, Phase 2 study to assess the efficacy, safety and tolerability, and pharmacokinetics of brensocatib administered once daily for 24 weeks in patients with NCFBE. The WILLOW study was conducted at 116 sites and enrolled 256 adult patients diagnosed with NCFBE who had at least two documented pulmonary exacerbations in the 12 months prior to screening. Patients were randomized 1:1:1 to receive either 10 mg or 25 mg of brensocatib or matching placebo. The primary efficacy endpoint was the time to first pulmonary exacerbation over the 24-week treatment period in the brensocatib arms compared to the placebo arm.
WILLOW Efficacy Data
We announced topline data for the WILLOW study in February 2020 and full data for the WILLOW study in June 2020. In September 2020, final results from the WILLOW study were published online in the New England Journal of Medicine. The data demonstrate that the WILLOW study met its primary endpoint of time to first pulmonary exacerbation over the 24-week treatment period for both the 10 mg and 25 mg dosage groups of brensocatib compared to placebo (p=0.027, p=0.044, respectively). The risk of exacerbation at any time during the trial was reduced by 42% for the 10 mg group versus placebo (HR 0.58, p=0.029) and by 38% for the 25 mg group versus placebo (HR 0.62, p=0.046). In addition, treatment with brensocatib 10 mg resulted in a significant reduction in the rate of pulmonary exacerbations, a key secondary endpoint, versus placebo. Specifically, patients treated with brensocatib experienced a 36% reduction in the 10 mg arm (p=0.041) and a 25% reduction in the 25 mg arm (p=0.167) versus placebo. Change in concentration of active NE in sputum versus placebo from baseline to the end of the treatment period was also statistically significant (p=0.034 for 10 mg, p=0.021 for 25 mg).
WILLOW Safety and Tolerability Data
Brensocatib was generally well-tolerated in the study. Rates of AEs leading to discontinuation in patients treated with placebo, brensocatib 10 mg, and brensocatib 25 mg were 10.6%, 7.4%, and 6.7%, respectively. The most common AEs in patients treated with brensocatib were cough, headache, sputum increase, dyspnea, fatigue, and upper respiratory tract infection. Rates of adverse events of special interest (AESIs) in patients treated with placebo, brensocatib 10 mg, and brensocatib 25 mg, respectively, were as follows: rates of skin events (including hyperkeratosis) were 11.8%, 14.8%, and 23.6%; rates of dental events were 3.5%, 16.0%, and 10.1%; and rates of infections that were considered AESIs were 17.6%, 13.6%, and 16.9%.
Further Research and Development
In August 2019, we received notice from the FDA that we were awarded a development grant of $1.8 million for specific work to be performed on a PRO tool. The grant funding is for the development of a novel PRO tool for use in clinical trials to measure symptoms in patients with NCFBE with and without NTM lung infection.
We are currently advancing a clinical development program for brensocatib in CF. The CF Therapeutics Development Network (CFTDN) has sanctioned our study protocol for brensocatib in CF. The CFTDN is an organization composed of specialists in CF clinical research and is the largest CF clinical trials network globally. Feedback from the CFTDN does not have any bearing on FDA regulatory approval. The Phase 2, multiple-dose, pharmacokinetics/pharmacodynamics study, which includes both patients who are on background CFTR modulator drugs and patients who are not on CFTR modulator drugs, is underway. We have completed enrollment in the CFTR modulator group and are on track to have results from this arm of the study by the end of 2022. We also plan to explore the potential of brensocatib in additional neutrophil-mediated diseases, including CRSsNP and HS.
Market Opportunity for brensocatib in bronchiectasis
Bronchiectasis is a severe, chronic pulmonary disorder in which the bronchi become permanently dilated due to a cycle of infection, inflammation, and lung tissue damage. The condition is marked by frequent pulmonary exacerbations requiring antibiotic therapy and/or hospitalizations. Symptoms include chronic cough, excessive sputum production, shortness of breath, and repeated respiratory infections, which can worsen the underlying condition. Based on information from external sources, including market research funded by us and third parties, and internal analyses and calculations, we estimate the potential addressable market at launch in the US, the European 5 (comprised of France, Germany, Italy, Spain and the UK) and Japan will be as follows (approximately):

Treprostinil Palmitil Inhalation Powder
TPIP is an investigational inhaled formulation of a treprostinil prodrug that has the potential to address certain of the current limitations of existing prostanoid therapies. We believe that TPIP prolongs duration of effect and may provide patients with greater consistency in pulmonary arterial pressure reduction over time. Current inhaled prostanoid therapies must be dosed four to nine times per day. Reducing dose frequency has the potential to ease patient burden and improve compliance. Additionally, we believe that TPIP may be associated with fewer side effects, including severity and/or frequency of cough, headache, throat irritation, nausea, flushing and dizziness that are associated with high initial drug levels and local upper airway exposure when using current inhaled prostanoid therapies. We believe TPIP may offer a differentiated product profile for PH-ILD and PAH.
In February 2021, we announced topline results from the Phase 1 study of TPIP in healthy volunteers. The objective of this first-in-human single ascending dose and multiple ascending dose study was to assess the pharmacokinetics and tolerability profile of TPIP. Data from the study demonstrated that TPIP was generally well tolerated, with a pharmacokinetic profile that supports continued development with once-daily dosing. The most common AEs across all cohorts in the study were cough, dizziness, headache, and nausea. Most AEs were mild in severity and consistent in nature with those typically seen with other inhaled prostanoid therapies. There were few moderate AEs and no severe or serious AEs. Subjects in the multiple dose panel that incorporated an up-titration approach beginning at 112.5 µg once-daily and progressing to 225 µg once-daily reported fewer AEs compared to the panel dosed with 225 µg once-daily from the first dose.
Overall pharmacokinetic results demonstrated that treprostinil exposure (AUC and Cmax) was dose-proportional, with low to moderate inter-subject variability. Treprostinil was detected in the plasma at 24 hours at all doses and throughout the 48-hour sampling period for the two highest doses. Compared with currently available inhaled treprostinil therapy, TPIP showed substantially lower Cmax and longer half-life. Data from this study were presented in an oral session at the European Society of Cardiology Congress in August 2021.
We are advancing the development of TPIP with two studies in patients with PAH. The first is an open-label, proof-of-mechanism study to understand the impact of a single dose of TPIP on PVR over a 24-hour period. The second will aim to investigate the effect of TPIP on PVR and six-minute walk distance over a 16-week treatment period using an up-titration, once-daily dosing schedule. One patient has completed the 24-hour period study at a dose of 112.5 micrograms. This patient also went on to complete the 16-week extension period study and was titrated to a dose of 320 micrograms once daily, which was found to be safe and tolerable. We did not observe any safety concerns with TPIP, and the data suggested a trend towards improvement in various cardiac measures during the study period. Beyond PAH, we continue to explore potential development pathways for TPIP in patients with other rare pulmonary disorders, including PH-ILD. We initiated a Phase 2 study in patients with PH-ILD using an up-titration, once-daily dosing schedule in early 2022.
Translational Medicine
Our translational medicine efforts are comprised of the Company’s preclinical programs, advanced through our internal research and development and augmented through business development activities. In March 2021, we acquired a proprietary protein deimmunization platform, called Deimmunized by Design, focused on the reengineering of therapeutic proteins to evade immune recognition and reaction. In August 2021, we acquired Motus and AlgaeneX, preclinical stage companies engaged in the research, development and manufacturing of gene therapies for rare genetic disorders. We believe that animal studies may demonstrate the viability of these potential medicines to address serious unmet medical needs in various therapeutic areas.
Corporate Development
We plan to continue to develop, acquire, in-license or co-promote other products, product candidates and technologies, including those that address serious and rare diseases that currently have significant unmet needs. We are focused broadly on serious and rare disease therapeutics and prioritizing those areas that best align with our core competencies.

KEY COMPONENTS OF OUR RESULTS OF OPERATIONS
Product Revenues, Net
Product revenues, net, consist of net sales of ARIKAYCE. In October 2018, we began shipping ARIKAYCE to our customers in the US, which include specialty pharmacies and specialty distributors. In December 2020 and February 2021, we began commercial sales of ARIKAYCE in Germany and the Netherlands, respectively. In July 2021, we began recognizing product revenue from commercial sales of ARIKAYCE in Japan. We recognize revenue for product received by our customers net of allowances for customer credits, including prompt pay discounts, service fees, estimated rebates, including government rebates, such as Medicaid rebates and Medicare Part D coverage gap reimbursements in the US, and chargebacks.
Cost of Product Revenues (Excluding Amortization of Intangible Assets)
Cost of product revenues (excluding amortization of intangible assets) consist primarily of direct and indirect costs related to the manufacturing of ARIKAYCE sold, including third-party manufacturing costs, packaging services, freight, and allocation of overhead costs, in addition to royalty expenses and revenue-based milestones. We began capitalizing inventory upon FDA approval of ARIKAYCE. All costs related to inventory for ARIKAYCE prior to FDA approval were expensed as incurred and therefore not included in cost of product revenues.
Research and Development (R&D) Expenses
R&D expenses consist primarily of salaries, benefits and other related costs, including stock-based compensation, for personnel serving in our research and development functions, including medical affairs and program management. R&D expenses also includes other internal operating expenses, the cost of manufacturing product candidates, including the medical devices for drug delivery, for clinical study, the cost of conducting clinical studies, and the cost of conducting preclinical and research activities. In addition, R&D expenses include payments to third parties for the license rights to products in development (prior to marketing approval), such as brensocatib. Our R&D expenses related to manufacturing our product candidates and medical devices for clinical study are primarily related to activities at CMOs that manufacture brensocatib and TPIP. Our R&D expenses related to clinical trials are primarily related to activities at contract research organizations (CROs) that conduct and manage clinical trials on our behalf. These contracts with CROs set forth the scope of work to be completed at a fixed fee or amount per patient enrolled. Payments under these contracts with CROs primarily depend on performance criteria such as the successful enrollment of patients or the completion of clinical trial milestones as well as time-based fees. Expenses are accrued based on contracted amounts applied to the level of patient enrollment and to activity according to the clinical trial protocol. Deposits for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts are then recognized as an expense as the related goods are delivered or the services are performed.
Selling, General and Administrative (SG&A) Expenses
SG&A expenses consist primarily of salaries, benefits and other related costs, including stock-based compensation, for our non-employee directors and personnel serving in our executive, finance and accounting, legal and compliance, commercial and pre-commercial, corporate development, field sales, information technology and human resource functions. SG&A expenses also include professional fees for legal services, consulting services, including commercial activities, insurance, board of director fees, tax and accounting services and certain milestones related to ARIKAYCE.
Amortization of Intangible Assets
Upon commercialization of ARIKAYCE, our intangible assets began to be amortized over their estimated useful lives. The fair values assigned to our intangible assets are based on estimates and assumptions we believe are reasonable based on available facts and circumstances. Unanticipated events or circumstances may occur that require us to review the assets for impairment.
Change in Fair Value of Deferred and Contingent Consideration Liabilities
In connection with the Business Acquisition in August 2021, we recorded deferred and contingent consideration liabilities related to potential future milestone payments. Adjustments to the fair value are due to changes in: the probability of achieving milestones; our stock price; or certain other estimated assumptions. The change in fair value of deferred and contingent consideration liabilities is calculated quarterly with gains and losses recorded in the consolidated statements of comprehensive loss.
Investment Income and Interest Expense
Investment income consists of interest and dividend income earned on our cash and cash equivalents and marketable securities. Interest expense consists primarily of the accretion of debt discount, contractual interest costs and the amortization of debt issuance costs related to our debt. Debt discount was accreted prior to the adoption of ASU 2020-06, and debt issuance costs are amortized, to interest expense using the effective interest rate method over the term of the debt. Our balance sheet

reflects debt, net of the debt discount, debt issuance costs paid to the lender, and other third-party costs. Unamortized debt issuance costs associated with extinguished debt are expensed in the period of the extinguishment.
RESULTS OF OPERATIONS
COVID-19 Update
Our employees (other than our laboratory personnel) have been provided a flexible approach to where and how they work in order to more easily manage business and personal responsibilities. We have enhanced our internal communications and touch points to ensure connectivity to our workforce. For when employees do work from the office, all of our facilities have been appropriately evaluated and sanitized on a daily basis in line with state and CDC guidelines. We will continue to manage this situation with a focus on the safety of our employees, ARIKAYCE physicians, caregivers and patients.
Though we continue to see use of ARIKAYCE, including new patient adds and continued prescription renewals, there remains a general uncertainty regarding the impact of COVID-19 on all aspects of our business, including how it will impact our patients, physicians, employees, suppliers, vendors, business partners and distribution channels. While the pandemic did not materially affect our financial results and business operations through the six months ended June 30, 2022, we are unable to predict the impact that COVID-19 will have on our financial position and operating results in future periods due to these and other numerous uncertainties. We will continue to assess the evolving impact of the COVID-19 pandemic and will make adjustments to our operations as necessary.
Comparison of the Three Months Ended June 30, 2022 and 2021
Overview - Operating Results
Our operating results for the three months ended June 30, 2022, included the following:
Product revenues, net, increased $19.9 million as compared to the same period in the prior year as a result of the growth in ARIKAYCE sales;

The $2.8 million increase resulted primarily from a $2.6 million increase in other internal expenses due to resuming certain internal commercial meetings and increased travel expenses. We expect SG&A expenses to continue to increase due, in part, to commercial readiness activities for brensocatib.
Amortization of Intangible Assets
Amortization of intangible assets for both the three months ended June 30, 2022 and 2021 was $1.3 million. Amortization of intangible assets is comprised of amortization of acquired ARIKAYCE R&D and amortization of the milestones paid to PARI for the FDA and EC approvals of ARIKAYCE.
Change in Fair Value of Deferred and Contingent Consideration Liabilities
The change in fair value of deferred and contingent consideration liabilities for the three months ended June 30, 2022 was $(12.6) million. The change is related to the fair value of the potential future consideration to be paid to former equityholders of the acquired businesses. Adjustments to the fair value are due to changes in: the probability of achieving milestones; our stock price; or certain other estimated assumptions.
Interest Expense
Interest expense decreased to $3.4 million for the three months ended June 30, 2022 as compared to $10.3 million in the same period in 2021 due to the cessation of accreting debt discount in accordance with the adoption of ASU 2020-06.

LIQUIDITY AND CAPITAL RESOURCES
 Overview
     There is considerable time and cost associated with developing potential pharmaceutical products to the point of regulatory approval and commercialization. We commenced commercial shipments of ARIKAYCE in October 2018. We expect to continue to incur consolidated operating losses, including losses at our US and certain international entities, as we plan to fund R&D for ARIKAYCE, brensocatib, TPIP and our other pipeline programs, continue pre-commercial, commercialization and regulatory activities for ARIKAYCE, and other general and administrative activities.

Table of Contents
In May 2021, we completed an underwritten public offering of $575.0 million aggregate principal amount of the 2028 Convertible Notes, including the exercise in full of the underwriters' option to purchase additional 2028 Convertible Notes. Our net proceeds from the offering, after deducting underwriting discounts and offering expenses of $15.7 million, were $559.3 million. A portion of the net proceeds from the 2028 Convertible Notes was used to repurchase $225.0 million of our outstanding 2025 Convertible Notes. We recorded a loss on early extinguishment of debt of $17.7 million, primarily related to the premium paid on extinguishment of a portion of the 2025 Convertible Notes.
In May 2021, we also completed an underwritten public offering of 11,500,000 shares of our common stock, including 1,500,000 shares issued pursuant to the exercise in full of the underwriters' option to purchase additional shares from us, at a public offering price of $25.00 per share. Our net proceeds from the sale of the shares, after deducting the underwriting discounts and offering expenses of $17.5 million, were $270.1 million.
In the first quarter of 2021, we entered into a sales agreement with SVB Securities to sell shares of our common stock, with aggregate gross sales proceeds of up to $250.0 million, from time to time, through an ATM program, under which SVB Securities acts as sales agent. As of June 30, 2022, we had not sold or issued any shares under the ATM program.
We may need to raise additional capital to fund our operations, including the Phase 3 ASPEN study, the continued commercialization of ARIKAYCE, the ARISE and ENCORE clinical trials related to ARIKAYCE, launch readiness activities for the potential launch of brensocatib, if approved, other clinical trials for brensocatib, TPIP, and our future product candidates, and to develop, acquire, in-license or co-promote other products or product candidates, including those that address orphan or rare diseases. While we believe we currently have sufficient funds to meet our financial needs for at least the next 12 months, we expect to opportunistically raise additional capital and may do so through equity or debt financing(s), strategic transactions or otherwise. Our cash requirements for the next 12 months will be impacted by a number of factors, the most significant of which we expect to be the ASPEN trial, expenses related to our commercialization efforts and our ARISE and ENCORE clinical trials for ARIKAYCE, and other development activities for brensocatib, and to a lesser extent, expenditures related to the clinical development of TPIP and other product candidates.
Cash Flows
As of June 30, 2022, we had cash and cash equivalents of $416.1 million, as compared with $716.8 million as of December 31, 2021. In addition, as of June 30, 2022, we had marketable securities of $148.6 million. The $300.7 million decrease in cash and cash equivalents was primarily due to the purchase of marketable securities and cash used in operating activities. Our working capital was $560.9 million as of June 30, 2022, as compared with $701.9 million as of December 31, 2021.
Net cash used in operating activities was $207.5 million and $203.7 million for the six months ended June 30, 2022 and 2021, respectively. The net cash used in operating activities during the six months ended June 30, 2022 and 2021 was primarily for the commercial, clinical and manufacturing activities related to ARIKAYCE, as well as other SG&A expenses and clinical trial expenses related to brensocatib and TPIP. The increase in cash used in operating activities for the six months ended June 30, 2022 compared to the corresponding period in 2021 was primarily due to the increase in net loss, excluding the adjustments to reconcile net loss to net cash used in operating activities, partially offset by the decrease in working capital, driven primarily by deposits paid in 2021 to our CROs for our initiated clinical trials and the $12.5 million milestone payment to AstraZeneca in 2021 related to the first dosing in our Phase 3 ASPEN trial.
Net cash used in investing activities was $104.3 million and $4.7 million for the six months ended June 30, 2022 and 2021, respectively. The increase in 2022 is due to purchases of marketable securities.
Net cash provided by financing activities was $12.8 million and $604.3 million for the six months ended June 30, 2022 and 2021, respectively. The decrease in 2022 is due to net cash proceeds from the issuance and extinguishment of debt during the six months ended June 30, 2021.
Contractual Obligations
There were no material changes outside of the ordinary course of business in our contractual obligations during the six months ended June 30, 2022 from those disclosed in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Contractual Obligations” in our Annual Report on Form 10-K for the year ended December 31, 2021.
Off-Balance Sheet Arrangements
We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future material effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. We do not have any interest in special purpose entities, structured finance entities or other variable interest entities.
CRITICAL ACCOUNTING ESTIMATES

Table of Contents
There have been no material changes to our critical accounting policies and estimates as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2021. For the required interim disclosure updates related to our accounting policies and estimates, see Note 2 to our consolidated financial statements — Summary of Significant Accounting Policies in this Quarterly Report on Form 10-Q.
ITEM 3.                                                QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
As of June 30, 2022, our cash and cash equivalents were in cash accounts and money market funds. Our investments in money market funds are not insured by the federal government. As of June 30, 2022, our marketable securities were invested in US treasury notes with an original maturity of greater than 90 days.
As of June 30, 2022, we had $800.0 million of convertible notes outstanding. Our 2025 Convertible Notes and our 2028 Convertible Notes bear interest at a coupon rate of 1.75% and 0.75%, respectively. If a 10% change in interest rates had occurred on June 30, 2022, it would not have had a material effect on the fair value of our debt as of that date, nor would it have had a material effect on our future earnings or cash flows.
The majority of our business is conducted in US dollars. However, we do conduct certain transactions in other currencies, including Euros, British Pounds, and Japanese Yen. Historically, fluctuations in foreign currency exchange rates have not materially affected our results of operations and during the six months ended June 30, 2022 and 2021, our results of operations were not materially affected by fluctuations in foreign currency exchange rates.
ITEM 4.                                                CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2022. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934, as amended (the Exchange Act), means controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit with the SEC is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and to ensure that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Based on that evaluation as of June 30, 2022, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level.
Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) during the six months ended June 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
PART II. OTHER INFORMATION
ITEM 1.                                                LEGAL PROCEEDINGS
