Alkermes plc

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Alkermes plc (the “Company”) is a global biopharmaceutical company that seeks to develop innovative medicines in the field of neuroscience. The Company has a portfolio of proprietary commercial products for the treatment of alcohol dependence, opioid dependence, schizophrenia and bipolar I disorder and a pipeline of clinical and preclinical candidates in development for neurological disorders. Headquartered in Dublin, Ireland, the Company has a research and development center in Waltham, Massachusetts; a research and manufacturing facility in Athlone, Ireland; and a manufacturing facility in Wilmington, Ohio.

On November 15, 2023, the Company completed the separation of its oncology business into Mural Oncology plc (“Mural”), a new, independent, publicly-traded company (the “Separation”). The Separation was effected by means of a distribution of all of the outstanding ordinary shares of Mural to the Company’s shareholders (the “Distribution”), in which each of the Company’s shareholders received one ordinary share, nominal value $0.01 per share, of Mural for everyten ordinary shares, par value $0.01 per share, of the Company (the “Distribution Ratio”) held by such shareholder as of the close of business on November 6, 2023, the record date for the Distribution (the “Record Date”). The historical results of the oncology business have been reflected as discontinued operations in the Company’s consolidated financial statements through November 15, 2023 (the “Separation Date”). For additional information related to the Separation, see Note 3, Discontinued Operations in these “Notes to Consolidated Financial Statements” in this Annual Report.

On December 14, 2023 the Company announced that it entered into a definitive agreement to sell its development and manufacturing facility located in Athlone, Ireland (the “Athlone Facility”) to Novo Nordisk (“Novo”) and plans to enter into subcontracting arrangements to continue certain development and manufacturing activities currently performed at the Athlone Facility for a period of time after the closing of the transaction, which arrangements may continue through the end of 2025. Such transaction is expected to close in mid-2024, subject to certain closing conditions. At December 31, 2023, the Company had classified the assets described under the related asset purchase agreement as “Assets held for sale” within the accompanying consolidated balance sheet.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of Alkermes plc and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated. Columns and rows within tables may not sum due to rounding.

Reclassification

The Company has presented its former oncology business as discontinued operations in its consolidated financial statements for all periods presented. See Note 3, Discontinued Operations in these “Notes to Consolidated Financial Statements” in this Annual Report for additional information. Additionally, as a result of the planned sale of the Athlone Facility, the Company has classified the assets described under the related asset purchase agreement as held for sale. The Company’s historical financial statements and footnotes have been recast accordingly.

The Company determined that the separation of its oncology business in November 2023 met the criteria for classification of the oncology business as discontinued operations in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 205, Discontinued Operations. Accordingly, the accompanying consolidated financial statements have been updated to present the assets and liabilities associated with the oncology business as discontinued operations as of December 31, 2022 on the consolidated balance sheets, and the results of the oncology business as discontinued operations through the Separation Date for the years ended December 31, 2023, 2022 and 2021 in the consolidated statements of operations and comprehensive income (loss).

Assets Held for Sale

In connection with the planned sale of the Athlone Facility, the Company reviewed FASB ASC 805, Business Combinationsand, based on the definitions therein, has determined that the Athlone Facility constitutes a business. Accordingly, the assets associated with the planned sale of the Athlone Facility have been classified as “Assets held for sale” within the accompanying consolidated balance sheets as of December 31, 2023 and 2022.

Use of Estimates

The preparation of the Company’s consolidated financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”) requires that Company management make estimates, judgments and assumptions that may affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, judgments and methodologies, including but not limited to, those related to revenue from contracts with its customers and related allowances, impairment and amortization of intangibles and long-lived assets, share-based compensation, income taxes including the valuation allowance for deferred tax assets, valuation of investments and litigation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions.

Cash and Cash Equivalents

The Company values its cash and cash equivalents at cost plus accrued interest, which the Company believes approximates their market value. The Company considers as cash equivalents only those investments that are highly liquid, readily convertible into cash and so near their maturity (generally three months from the date of purchase) that they present insignificant risk of change in value because of interest rate changes.

Investments

The Company has investments in various types of securities, consisting primarily of United States (“U.S.”) government and agency obligations, corporate debt securities and debt securities issued by non-U.S. agencies and backed by non-U.S. governments. The Company generally holds its interest-bearing investments with major financial institutions and in accordance with documented investment policies. The Company limits the amount of credit exposure to any one financial institution or corporate issuer. At December 31, 2023, substantially all these investments were classified as available-for-sale and were recorded at fair value.

Unrealized gains and losses are included in accumulated other comprehensive loss in equity, net of related tax, unless: (i) the security has experienced a credit loss; (ii) the Company has determined that it has the intent to sell the security; or (iii) the Company has determined that it is more likely than not that it will have to sell the security before its expected recovery. Periodic reviews are conducted to identify and evaluate each investment that has an unrealized loss in accordance with the meaning of other-than-temporary impairment. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis.

For available-for-sale debt securities with unrealized losses, the Company performs an analysis to assess whether it intends to sell, or whether it would more likely than not be required to sell, the security before the expected recovery of the amortized cost basis. Where the Company intends to sell a security, or may be required to do so, the security’s decline in fair value is deemed to be other-than-temporary and the full amount of the unrealized loss is reflected in earnings as an impairment loss.

Regardless of the Company’s intent to sell a security, the Company performs additional analysis on all securities with unrealized losses to evaluate losses associated with the creditworthiness of the security. Credit losses are identified where the Company does not expect to receive cash flows sufficient to recover the amortized cost basis of a security.

The Company’s held-to-maturity investments are restricted investments held as collateral under letters of credit related to certain of the Company’s agreements and are included in “Investments—long-term,” in the accompanying consolidated balance sheets.

Fair Value of Financial Instruments

The Company’s financial assets and liabilities are recorded at fair value and are classified as Level 1, 2 or 3 within the fair value hierarchy, as described in the accounting standards for fair value measurement. At December 31, 2023, the Company’s financial assets consisted of cash equivalents and investments and are classified within the fair value hierarchy as follows:

•

Level 1–these valuations are based on a market approach using quoted prices in active markets for identical assets. Valuations of these products do not require a significant degree of judgment. Assets utilizing Level 1 inputs at December 31, 2023 included U.S. treasury securities, marketable securities classified as cash equivalents and a fixed term deposit account; and

•

Level 2–these valuations are based on quoted prices for identical or similar assets in active markets or other market observable inputs such as interest rates, yield curves, foreign currency spot rates and option pricing valuation models. Assets utilizing Level 2 inputs at December 31, 2023 included U.S. government agency debt securities, debt securities issued by non-U.S. agencies and backed by non-U.S. governments and investments in corporate debt securities that are trading in the credit markets.

The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents, accounts receivable, other current assets, accounts payable and accrued expenses approximate fair value due to their short-term nature.

Inventory

Inventory is stated at the lower of cost and net realizable value. Cost is determined using the first-in, first-out method. Included in inventory are raw materials used in production of preclinical and clinical products, which have alternative future use and are charged to R&D expense when consumed. The cost elements included within inventory include three primary categories for commercial products: cost of raw materials; direct labor; and overhead. Overhead is based on the normal capacity of the Company’s production facilities and does not include costs from abnormally low production or idle capacity, which are expensed directly to the consolidated statement of operations and comprehensive income (loss).

The Company capitalizes inventory costs associated with its products prior to regulatory approval when, based on management’s judgment, future commercialization of the product is considered probable and future economic benefit from such product is expected to be realized. The Company assesses the regulatory approval process and where the particular product stands in relation to that approval process, including any known safety, efficacy or quality concerns, potential labeling restrictions and other potential impediments to approval. The Company also considers the shelf life of the product in relation to the expected timeline for approval and considers issues that may prevent or delay commercialization, including issues that may arise in relation to the manufacturing of the product. The Company expenses previously capitalized costs related to pre-approval inventory upon a change in such judgment, due to, among other potential factors, a denial or significant delay of approval by relevant regulatory agencies or other issues that may make the pre-approval inventory batches less likely or unlikely to be commercialized and to result in future economic benefit.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost, subject to review for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Expenditures for repairs and maintenance are charged to expense as incurred and major renewals and improvements are capitalized. Depreciation is calculated using the straight-line method over the following estimated useful lives of the assets:

Goodwill and Intangible Assets

Goodwill represents the excess cost of the Company’s investment in the net assets of acquired companies over the fair value of the underlying identifiable net assets at the date of acquisition. The Company’s goodwill consists solely of goodwill created as a result of the Company’s acquisition of Elan Drug Technologies (“EDT”) from Elan Corporation, plc (such acquisition, the “Business Combination”) in September 2011 and has been assigned to one reporting unit. A reporting unit is an operating segment or one level below an operating segment or a component to which goodwill is assigned when initially recorded.

Goodwill is not amortized but is reviewed for impairment on an annual basis, as of October 31, and whenever events or changes in circumstances indicate that the carrying value of the goodwill might not be recoverable. The Company has the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. If the Company elects this option and believes, as a result of the qualitative assessment, that it is more-likely-than-not that the fair value of its reporting unit is less than its carrying amount, the quantitative impairment test is required; otherwise, no further testing is required. Alternatively, the Company may elect to not first assess qualitative factors and immediately perform the quantitative impairment test. In the quantitative impairment test, the Company compares the fair value of its reporting unit to its carrying value. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then the Company would record an impairment loss equal to the difference.

When some, but not all, of a reporting unit is to be disposed of, the accounting for that reporting unit’s goodwill will depend on whether the disposal group constitutes a business. If the disposal group constitutes a business, the Company attributes a portion of the reporting unit’s goodwill to the disposal group based on the relative fair values of: (i) the disposal group; and (ii) the portion of the reporting unit that will be retained.

The Company’s finite-lived intangible assets, consisting of core developed technology and collaboration agreements acquired as part of the Business Combination, were recorded at fair value at the time of their acquisition and are stated within the Company’s consolidated balance sheets net of accumulated amortization. The finite-lived intangible assets are amortized over their estimated useful lives using the economic use method, which reflects the pattern that the economic benefits of the intangible assets are consumed as revenue is generated from the underlying patent or contract. The useful lives of the Company’s intangible assets are primarily based on the legal or contractual life of the underlying patent or contract, which does not include additional years for the potential extension or renewal of the contract or patent.

Impairment of Long-Lived Assets

The Company reviews long-lived assets to be held and used for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset; a significant change in the extent or manner in which an asset is used; a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset; an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset; a current-period operating or cash flow loss combined with a history of operating or cash-flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset; or a current expectation that, more likely than not, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the assets, the assets are written-down to their estimated fair values. Long-lived assets to be disposed of are carried at fair value less costs to sell them.

Revenue from Contracts with Customers

The Company recognizes revenue in accordance with FASB ASC 606, Revenue from Contracts with Customers (“Topic 606”). When entering into arrangements with customers, the Company identifies whether its performance obligations under the arrangement represent a distinct good or service or a series of distinct goods or services. If a contract contains more than one performance obligation, the Company allocates the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. The fair value of performance obligations under the arrangement may be derived using an estimate of selling price if the Company does not sell the goods or services separately.

The Company recognizes revenue when or as it satisfies a performance obligation by transferring an asset or providing a service to a customer. Management judgment is required in determining the consideration to be earned under an arrangement and the period over which the Company is expected to complete its performance obligations under an arrangement. Steering committee services that are not inconsequential or perfunctory and that are determined to be performance obligations are combined with other research services or performance obligations required under an arrangement, if any, in determining the level of effort required in an arrangement and the period over which the Company expects to complete its aggregate performance obligations.

The Company’s product sales, net consist of sales in the U.S. of VIVITROL®, ARISTADA®and ARISTADA INITIO® and LYBALVI®, primarily to wholesalers, specialty distributors and pharmacies. Product sales, net are recognized when the customer obtains control of the product, which is when the product has been received by the customer.

Revenues from product sales are recorded net of reserves established for applicable discounts and allowances that are offered within contracts with the Company’s customers, healthcare providers or payers. The Company’s process for estimating reserves established for these variable consideration components does not differ materially from historical practices. The transaction price, which includes variable consideration reflecting the impact of discounts and allowances, may be subject to constraint and is included in the net sales price only to the extent that it is probable that a significant reversal of the amount of the cumulative revenues recognized will not occur in a future period. Actual amounts may ultimately differ from the Company’s estimates. If actual results vary, the Company adjusts these estimates, which could have an effect on earnings in the period of adjustment. The following are the Company’s significant categories of sales discounts and allowances:

•

Medicaid Rebates—the Company records accruals for rebates to U.S. states under the Medicaid Drug Rebate Program as a reduction of sales when the product is shipped into the distribution channel using the expected value method. The Company rebates individual U.S. states for all eligible units purchased under the Medicaid program based on a rebate per unit calculation, which is based on the Company’s average manufacturer prices. The Company estimates expected unit sales to individuals covered by Medicaid and rebates per unit under the Medicaid program and adjusts its rebate accrual based on actual unit sales and rebates per unit and changes in trends in Medicaid utilization. To date, actual Medicaid rebates have not differed materially from the Company’s estimates;

•

Chargebacks—discounts that occur when contracted indirect customers purchase directly from wholesalers and specialty distributors. Contracted customers generally purchase a product at its contracted price. The wholesaler or specialty distributor, in turn, then generally charges back to the Company the difference between the wholesale acquisition cost and the contracted price paid to the wholesaler or specialty distributor by the customer. The allowance for chargebacks is made using the expected value method and is based on actual and expected utilization of these programs. Chargebacks could exceed historical experience and the Company’s estimates of future participation in these programs. To date, actual chargebacks have not differed materially from the Company’s estimates;

•

Product Discounts—cash consideration, including sales incentives, given by the Company under agreements with a number of wholesaler, distributor, pharmacy, and treatment provider customers that provide them with a discount on the purchase price of products. The reserve is made using the expected value method and to date, actual product discounts have not differed materially from the Company’s estimates;

•

Product Returns—the Company records an estimate for product returns at the time its customers take control of their product. The Company estimates this liability using the expected returns of product sold based on historical return levels and specifically identified anticipated returns due to known business conditions and product expiry dates. Return amounts are recorded as a reduction of sales. Once product is returned, it is destroyed. To date, actual product returns have not differed materially from the Company’s estimates; and

•

Medicare Part D—the Company records accruals for Medicare Part D liabilities under the Medicare Coverage Gap Discount Program (“CGDP”) as a reduction of sales. Under the CGDP, patients reaching the annual coverage gap threshold are eligible for reimbursement coverage for out-of-pocket costs for covered prescription drugs. Under an agreement with the Centers for Medicare and Medicaid Services, manufacturers are responsible to reimburse prescription plan sponsors for the portion of out-of-pocket expenses not covered under their Medicare plans. To date, actual Medicare Part D rebates have not differed materially from the Company’s estimates.

Collaborative Arrangements

The Company has entered into collaborative arrangements with pharmaceutical companies including, among others, Janssen Pharmaceuticals, Inc. (“Janssen, Inc.”), Janssen Pharmaceutica International, a division of Cilag International AG (“Janssen International”), and Janssen Pharmaceutica N.V. (together with Janssen, Inc., Janssen International and their affiliates, “Janssen”) related to INVEGA SUSTENNA®/XEPLION®, INVEGA TRINZA®/TREVICTA®, INVEGA HAFYERA®/BYANNLI® (the “long-acting INVEGA products”) and RISPERDAL CONSTA®, and Biogen Swiss Manufacturing GmbH (together with its affiliates, “Biogen”) related to VUMERITY®. Substantially all of the products developed under these arrangements are currently being marketed as approved products for which the Company receives payments for manufacturing services and/or royalties on net product sales.

Manufacturing Revenue

The Company recognizes manufacturing revenues from the sale of products it manufactures for resale by its licensees. Substantially all of the manufacturing revenues are recognized at a point in time when control of the product passes to the licensee. The sales price for certain of the Company’s manufacturing revenues is based on the end-market sales price earned by its licensees. As end-market sales generally occur after the Company has recorded manufacturing revenue, the Company estimates the sales price for such products based on information supplied to it by the Company’s licensees, its historical transaction experience and other third-party data. Differences between actual manufacturing revenues and estimated manufacturing revenues are reconciled and adjusted for in the period in which they become known, which is generally within the same quarter. The differences between the Company’s actual and estimated manufacturing revenues have not been material to date.

Royalty Revenue

The Company recognizes royalty revenues related to the sale by its licensees of products that incorporate the Company’s technologies. All of the Company’s royalties qualify for the sales-and-usage exemption under Topic 606 as (i) such royalties are based strictly on the sales-and-usage by the licensee; and (ii) a license of IP is the sole or predominant item to which such royalties relate. Based on this exemption, these royalties are earned in the period that the products are sold by the Company’s licensee and the Company has a present right to payment.

Certain of the Company’s royalty revenues are recognized by the Company based on information supplied to the Company by its licensees and require estimates to be made. Differences between actual royalty revenues and estimated royalty revenues are reconciled and adjusted for in the period in which they become known, which is generally within the same quarter. The differences between the Company’s actual and estimated royalty revenues have not been material to date.

License Revenue

The Company recognizes revenue from the grant of distinct, right-to-use licenses of IP when control of the license is transferred to the licensee, which is the point in time that the licensee is able to direct the use of, and obtain substantially all of the benefits from the license.

Receivables, net

Receivables, net, include amounts billed and amounts unbilled but currently unconditionally due from customers. The amounts due are stated at their net estimated realizable value. The Company’s unbilled receivable balance was $103.1 million and $72.0 million at December 31, 2023 and 2022, respectively, and related primarily to royalty revenue. The Company maintains an allowance for doubtful accounts to provide for the estimated amounts of receivables that will not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience, the age of outstanding receivables and collateral to the extent applicable. The Company’s allowance for doubtful accounts was approximately $0.2 million at each of December 31, 2023 and 2022.

Contract Assets

Contract assets include unbilled amounts that will result in a sale under certain of the Company’s manufacturing contracts. The amounts included in the contract assets table below are classified as “Current assets” in the accompanying consolidated balance sheets, as they relate to manufacturing processes that are completed inten days toeight weeks.

Contract assets consisted of the following:

Contract Liabilities

Contract liabilities consist of contractual obligations related to deferred revenue. At December 31, 2023 and 2022, $2.7 million and $6.8 million of the contract liabilities, respectively, were classified as “Contract liabilities–short-term” in the accompanying consolidated balance sheets and $2.1 million and $3.9 million of the contract liabilities, respectively, were classified as “Other long-term liabilities” in the accompanying consolidated balance sheets.

Contract liabilities consisted of the following:

Foreign Currency

The Company’s functional and reporting currency is the U.S. dollar. Transactions in foreign currencies are recorded at the exchange rate prevailing on the date of the transaction. The resulting monetary assets and liabilities are translated into U.S. dollars at exchange rates prevailing on the subsequent balance sheet date. Gains and losses as a result of translation adjustments are recorded within “Other (expense) income, net” in the accompanying consolidated statements of operations and comprehensive income (loss). During the years ended December 31, 2023, 2022 and 2021, the Company recorded a loss of $0.5 million, a gain of $0.7 million and a loss of $0.3 million, respectively, on foreign currency translation.

Concentrations

Financial instruments that potentially subject the Company to concentrations of credit risk are receivables and marketable securities. Billings to large pharmaceutical companies and pharmaceutical wholesalers account for the majority of the Company’s receivables, and collateral is generally not required from these customers. To mitigate credit risk, the Company monitors the financial performance and credit-worthiness of its customers. The following represents revenue and receivables from the Company’s customers exceeding 10% of the total in each category as of, and for the years ended, December 31, 2023, 2022 and 2021:

The Company holds its interest-bearing investments with major financial institutions and, in accordance with documented investment policies, the Company limits the amount of credit exposure to any one financial institution or corporate issuer. The Company’s investment objectives are, first, to ensure liquidity and conservation of capital and, second, to obtain investment income.

Geographic Information

Company revenues by geographic location for the years ended December 31, 2023, 2022 and 2021, as determined by the location of the customer, are as follows:

The location of the Company’s assets are as follows:

(1)

Prior period amounts have been retrospectively adjusted to reflect assets related to discontinued operations related to the Separation and assets held for sale related to the planned sale of the Athlone Facility.

Research and Development Expenses

For each of its R&D programs, the Company incurs both external and internal expenses. External R&D expenses include fees related to clinical and preclinical activities performed by contract research organizations, consulting fees and costs related to laboratory services, purchases of drug product materials and third-party manufacturing development costs. Internal R&D expenses include employee-related expenses, occupancy costs, depreciation and general overhead. The Company tracks external R&D expenses for each of its development programs, however, internal R&D expenses are not tracked by individual program as they benefit multiple development programs or the Company’s products or technologies in general.

Selling, General and Administrative Expenses

Selling, general and administrative (“SG&A”) expenses are primarily comprised of employee-related expenses associated with selling and marketing, finance, human resources, legal, information technology and other administrative personnel, outside marketing, advertising, financial and legal expenses and other general and administrative costs.

Advertising costs are expensed as incurred. During the years ended December 31, 2023, 2022 and 2021, advertising costs totaled $127.6 million, $41.4 million and $38.9 million, respectively.

Share-Based Compensation

The Company’s share-based compensation programs permit grants of awards in the form of stock options and restricted stock unit awards (“RSUs”), which vest with the passage of time and/or based on the achievement of certain performance criteria. The Company issues new shares upon the exercise of stock options or the vesting of RSUs. Under the terms of the Company’s stock option and incentive plans (the “Plans”), the Company’s employees may, at the discretion of the plan administrator, become eligible in certain circumstances set forth in the Plans for accelerated vesting of certain awards granted to them under the Plans. In such circumstances, if there are no effective future service requirements for such employees, the remaining fair value of any such accelerated awards would be expensed as of the date of acceleration.

Time-Based Stock Options

Except as otherwise provided in the applicable Plan or award certificate, stock option grants to employees expireten years from the date of grant and generally vest infour equal annual installments, commencing on the first anniversary of the date of grant, provided the employee remains continuously employed with the Company during the applicable vesting period. Except as otherwise provided in the applicable Plan: (i) annual stock option grants to non-employee directors expireten years from the grant date and generally vest over aone-year period, provided that the director continues to serve on the Company’s board of directors through the vesting date; and (ii) stock option grants to new non-employee directors expireten years from the grant date and generally vest over athree-year period, provided that the director continues to serve on the Company’s board of directors through the vesting date. The estimated fair value of options is recognized over the requisite service period, which is generally the vesting period. Share-based compensation expense is based on awards ultimately expected to vest. Forfeitures are estimated based on historical experience at the time of grant and revised in subsequent periods if actual forfeitures differ from those estimates.

The fair value of stock option grants is based on estimates as of the date of grant using a Black-Scholes option valuation model. The Company uses historical data as the basis for estimating stock option terms and forfeitures. Separate groups of employees that have similar historical stock option exercise and forfeiture behavior are considered separately for valuation purposes. The ranges of expected terms disclosed below reflect different expected behavior among certain groups of employees. Expected stock volatility factors are based on a weighted average of implied volatilities from traded options of the Company’s ordinary shares and historical share price volatility of the Company’s ordinary shares, which is determined based on a review of the weighted average of historical weekly price changes of the Company’s ordinary shares. The risk-free interest rate for periods commensurate with the expected term of the stock option is based on the U.S. treasury yield curve in effect at the time of grant. The dividend yield on the Company’s ordinary shares is estimated to be zero as the Company has not paid dividends and does not expect to pay dividends in the near future. The exercise price of options granted is equal to the closing price of the Company’s ordinary shares traded on the Nasdaq Global Select Market on the date of grant.

The fair value of each stock option granted was estimated on the grant date with the following weighted-average assumptions:

Time-Based Restricted Stock Unit Awards

Except as otherwise provided in the applicable Plan or award certificate, time-based RSUs awarded to employees generally vest infour equal annual installments, commencing on the first anniversary of the date of grant, provided the employee remains continuously employed with the Company during the applicable vesting period. Shares subject to these RSUs are delivered to the employee upon vesting, subject to payment of applicable withholding taxes. The fair value of time-based RSUs is equal to the closing price of the Company’s ordinary shares traded on the Nasdaq Global Select Market on the date of grant. Compensation expense, including the effect of forfeitures, is recognized over the applicable service period.

Performance-Based Restricted Stock Unit Awards

Performance-based RSUs awarded to employees vest upon the achievement of certain performance criteria, typically during or at the end of a specified performance period. The estimated fair value of these RSUs are generally based on the closing price of the Company’s ordinary shares traded on the Nasdaq Global Select Market on the date of grant, unless the RSU is also subject to a market condition. In that case, the fair value of the RSU is based on a Monte Carlo simulation model. Compensation expense for performance-based RSUs is recognized from the date the Company determines the performance criteria probable of being achieved to the date the award, or relevant portion of the award, is expected to vest. Cumulative adjustments are recorded on a quarterly basis to reflect subsequent changes to the estimated outcome of the performance criteria until the date that the final outcome of the performance criteria is determined.

Conversion and modification of equity awards outstanding at Separation date

In connection with the Separation, and in accordance with the provisions of the Alkermes Stock Option and Incentive Plans (as defined in Note 15, Share-based Compensation) and the terms of that certain employee matters agreement, dated as of November 13, 2023, as amended, by and between the Company and Mural (the “Employee Matters Agreement”), outstanding stock options, RSUs and performance-based RSUs were adjusted (an equitable adjustment) in order to preserve the intrinsic value of such awards immediately before and immediately after the Separation Date. Based upon the terms and the methodology set forth in the Employee Matters Agreement, one conversion ratio was calculated for awards held by current and former employees of the Company (the “Alkermes Conversion Ratio”), a second conversion ratio was calculated for stock options held by employees who transferred to Mural in connection with the Separation and a third conversion ratio was calculated for RSUs held by employees who transferred to Mural in connection with the Separation (the “Mural Conversion Ratios”).

Following the application of the Alkermes Conversion Ratio to applicable awards that were outstanding immediately before the Separation Date, the Company compared the fair value of such awards to the fair value of the awards that were outstanding immediately after the Separation Date, as adjusted, to determine whether the Company would recognize an incremental fair value adjustment related to the awards. Following this calculation, it was determined that no incremental fair value resulted from the application of the Alkermes Conversion Ratio.

Following the application of the applicable Mural Conversion Ratios to applicable awards that were outstanding immediately before the Separation Date, Mural compared the fair value of such awards to the fair value of the awards that were outstanding immediately after the Separation Date, as adjusted, to determine whether an incremental fair value adjustment was required. Following this calculation, it was determined that the fair value of the post-conversion awards held by employees who transferred to Mural increased immediately following the Separation, resulting in an incremental fair value charge as of the Separation Date. In accordance with FASB ASC 718, Compensation—Stock Compensation, the Company recognized a charge within share-based compensation expense of $1.6 million, which represented the incremental fair value related to stock option awards that had vested prior to the Separation Date.

Income Taxes

The Company recognizes income taxes under the asset and liability method. Deferred income taxes are recognized for differences between the financial reporting and tax bases of assets and liabilities at enacted statutory tax rates in effect for the years in which the differences are expected to reverse. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. In evaluating the Company’s ability to recover its deferred tax assets, the Company considers all available positive and negative evidence including its past operating results, the existence of cumulative income in the most recent fiscal years, changes in the business in which the Company operates and its forecast of future taxable income. In determining future taxable income, the Company is responsible for assumptions utilized including the amount of Irish and non-Irish pre-tax operating income, the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates that the Company is using to manage the underlying business.

The Company accounts for uncertain tax positions using a more-likely-than-not threshold for recognizing and resolving uncertain tax positions. The evaluation of uncertain tax positions is based on factors including, but not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. The Company evaluates its tax position on a quarterly basis. The Company also accrues for potential interest and penalties related to unrecognized tax benefits in income tax expense.

Comprehensive Income (Loss)

Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) includes changes in equity that are excluded from net income (loss), such as unrealized holding gains and losses on available-for-sale investments.

Earnings (Loss) Per Share

Basic earnings (loss) per ordinary share from continuing operations is calculated based upon net income (loss) from continuing operations available to holders of ordinary shares divided by the weighted average number of ordinary shares outstanding. Basic loss per ordinary share from discontinued operations is calculated based upon net loss from discontinued operations available to holders of ordinary shares, divided by the weighted average number of ordinary shares outstanding. For the calculation of diluted earnings (loss) per ordinary share from continuing operations and discontinuing operations, the Company utilizes the treasury stock method and adjusts the weighted average number of ordinary shares outstanding for the potential dilutive effect of outstanding ordinary share equivalents such as stock options and RSUs.

The Company is currently evaluating the impact this ASU will have on its consolidated financial statements and related disclosures.

3. DISCONTINUED OPERATIONS

Mural Oncology Separation

On November 15, 2023, the Company completed the Separation. In connection with the Separation, the Company entered into a separation agreement with Mural, dated as of November 13, 2023, that, among other things, sets forth the Company’s agreements with Mural regarding the principal actions taken or to be taken in connection with the Separation, including the Distribution. The separation agreement identified those assets to be transferred to, liabilities to be assumed by and contracts to be assigned to Mural, including the operating lease for the office and laboratory space at 852 Winter Street in Waltham, Massachusetts, as part of the Separation, and it provided for when and how such transfers, assumptions and assignments were to occur. The purpose of the separation agreement was to provide Mural and the Company with those assets necessary to operate their respective businesses and to retain or assume the respective liabilities related to those assets.

Under the terms of the separation agreement, the Company granted Mural a perpetual, worldwide, non-exclusive, royalty-free, fully paid-up license (or, as the case may be, sublicense) to IP controlled by the Company as of the date of the Distribution to allow Mural to use such IP for the oncology business, and Mural granted the Company a perpetual, worldwide, non-exclusive, royalty-free, fully paid-up license (or, as the case may be, sublicense) to IP transferred to Mural as part of the Separation for the Company’s use outside of the oncology business.

Each of Mural and the Company agreed to releases with respect to pre-Distribution claims, and cross-indemnities with respect to post-Distribution claims, that are principally designed to place financial responsibility for the obligations and liabilities allocated to Mural under the separation agreement with Mural, and financial responsibility for the obligations and liabilities allocated to the Company under the separation agreement with the Company. The Company and Mural are also each subject to mutual six-month employee non-solicitation and non-hire restrictions, subject to certain customary exceptions, and certain confidentiality restrictions and information sharing obligations.

The transfer of assets and liabilities to Mural was effected through a contribution in accordance with the separation agreement, as summarized below:

The Company determined that the Separation and related Distribution qualified as tax-free for U.S. federal income tax purposes, which required significant judgment by management. In making such determinations, the Company applied U.S. federal tax law to relevant facts and circumstances and obtained: (i) a favorable private letter ruling from the IRS; (ii) a tax opinion; and (iii) other external tax advice related to the concluded tax treatment. If the Separation and Distribution were to ultimately fail to qualify for tax-free treatment for U.S. federal income tax purposes, the Company and/or its shareholders could be subject to significant liabilities, which could have material adverse impacts on the Company’s business, financial condition, results of operations and cash flows in future reporting periods. Furthermore, other than taxes recorded on the transfer of intellectual property, the Company determined that the Separation and related Distribution qualified as tax-free for Irish tax purposes, which required significant judgment by management. In making such determinations, the Company applied Irish tax law to relevant facts and circumstances and obtained: (i) a tax opinion; and (ii) other external tax advice related to the concluded tax treatment. If the Separation and Distribution were to ultimately fail to qualify for tax-free treatment for Irish tax purposes, the Company and/or its shareholders could be subject to significant liabilities, which could have material adverse impacts on the Company’s business, financial condition, results of operations and cash flows in future reporting periods.

In connection with the Separation, the Company also entered into a tax matters agreement with Mural, dated as of November 13, 2023. The tax matters agreement governs the Company’s and Mural’s respective rights, responsibilities and obligations with respect to taxes (including taxes arising in the ordinary course of business and taxes, if any, incurred as a result of any failure of the Distribution, together with certain related transactions, to qualify as tax-free for U.S. federal income tax purposes), tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings, and assistance and cooperation in respect of tax matters.

In connection with the Separation, the Company also entered into the Employee Matters Agreement. The Employee Matters Agreement, as amended, governs the Company’s, Mural’s and their respective subsidiaries’ and affiliates’ rights, responsibilities and obligations after the Separation with respect to, employment, benefits and compensation matters relating to employees and former employees (and their respective dependents and beneficiaries) who are or were associated with the Company, including those who became employees of Mural in connection with the Separation; the allocation of assets and liabilities generally relating to employees, employment or service-related matters and employee benefit plans; other human resources, employment and employee benefits matters; and the treatment of equity-based awards granted by the Company prior to the Separation.

The Company entered intotwo transition services agreements with Mural. On November 13, 2023, Alkermes, Inc., a wholly-owned subsidiary of the Company (“Alkermes US”), and Mural Oncology, Inc., a wholly-owned subsidiary of Mural (“Mural US”), entered into one transition services agreement, pursuant to which the Company and its subsidiaries will provide, on an interim, transitional basis, various services to Mural and its subsidiaries, and a second transition services agreement, pursuant to which Mural and its subsidiaries will provide certain services to the Company and its subsidiaries, in each case for a term oftwo years, unless earlier terminated in accordance with the terms of the applicable agreement. As of December 31, 2023, the Company had an immaterial amount of accounts receivable and accounts payable due from and to Mural related to such transition services agreements.

The results of the oncology business and transaction costs related to the Separation have been reflected as “Loss from discontinued operations, net of taxes” in the accompanying consolidated statement of operations and comprehensive income (loss) through the Separation Date. Prior periods have been recast to reflect this presentation. The transaction costs related to the Separation were $36.0 million during 2023 and $1.4 million during 2022, and primarily relate to professional fees for separation activities within the finance, tax, legal and information technology functions. As of December 31, 2022, the assets and liabilities associated with the oncology business are classified as “Assets held for discontinued operations” and “Liabilities related to discontinued operations” in the accompanying consolidated balance sheet.

The following table summarizes expenses of the discontinued operations for the years ended December 31, 2023, 2022 and 2021:

There wereno assets and $4.5 million of liabilities related to the Separation as of December 31, 2023. All assets were transferred to Mural as of the Separation Date. The $4.5 million of liabilities classified as “Liabilities related to discontinued operations” in the accompanying consolidated balance sheet relates to bonus amounts accrued for employees that transferred to Mural during 2023 through the Separation Date that will be paid by the Company, in accordance with the terms of the Employee Matters Agreement. The following table summarizes the assets and liabilities related to Mural that have been classified as assets and liabilities from discontinued operations in our accompanying consolidated balance sheet as of December 31, 2022:

The following table summarizes the significant non-cash items and capital expenditures of the discontinued operations that are included in the consolidated statements of cash flows for the years ended December 31, 2023, 2022 and 2021:

4. REVENUE FROM CONTRACTS WITH CUSTOMERS

During the years ended December 31, 2023, 2022 and 2021, the Company recorded product sales, net, as follows:

During the years ended December 31, 2023, 2022 and 2021, the Company recorded manufacturing and royalty revenues from its collaboration arrangements as follows:

(1)

“long-acting INVEGA products”: INVEGA SUSTENNA/XEPLION (paliperidone palmitate), INVEGA TRINZA/TREVICTA (paliperidone palmitate) and INVEGA HAFYERA/BYANNLI (paliperidone palmitate).

In November 2021, the Company received notice of partial termination of an exclusive license agreement with Janssen. Under this license agreement, the Company provided Janssen with rights to, and know-how, training and technical assistance in respect of, the Company’s small particle pharmaceutical compound technology, known as NanoCrystal technology, which was used to develop the long-acting INVEGA products. When the partial termination became effective in February 2022, Janssen ceased paying royalties related to sales of INVEGA SUSTENNA, INVEGA TRINZA and INVEGA HAFYERA. Accordingly, the Company ceased recognizing royalty revenue related to sales of these products in February 2022. In April 2022, the Company commenced binding arbitration proceedings related to, among other things, Janssen’s partial termination of this license agreement and Janssen’s royalty and other obligations under the agreement. In May 2023, the arbitral tribunal (the “Tribunal”) in the arbitration proceedings issued a final award (the “Final Award”) which concluded the arbitration proceedings. The Final Award provided, among other things, that the Company was due back royalties of $195.4 million, inclusive of $8.1 million in late-payment interest related to 2022 U.S. net sales of the long-acting INVEGA products, which amount the Company received from Janssen in the second quarter of 2023, and is entitled to 2023 and future royalty revenues from Janssen related to net sales of INVEGA SUSTENNA through August 20, 2024, INVEGA TRINZA through the second quarter of 2030 (but no later than May 2030 when the license agreement expires) and INVEGA HAFYERA through May 2030 (when the license agreement expires).

Following issuance of the Final Award, the Company recognized royalty revenues related to the back royalties noted above and resumed recognizing royalty revenue related to ongoing U.S. sales of the long-acting INVEGA products. During 2023, the Company recorded $486.1 million in royalty revenue from sales of the long-acting INVEGA products, including $195.4 million related to back royalties and associated interest related to net sales of the long-acting INVEGA in the U.S. in 2022 and resumed recognizing royalty revenue related to worldwide net sales of the long-acting INVEGA products of approximately $290.7 million, as compared to royalty revenue of $115.7 million during 2022.

In October 2022 and November 2022, an arbitration panel found that the Company must return to Acorda Therapeutics, Inc. (“Acorda”) $16.5 million (inclusive of prejudgment interest and administrative fees) and $1.8 million(inclusive of prejudgment interest), respectively, previously paid by Acorda under a license agreement between the Company and Acorda. These amounts represented a portion of the royalty revenue paid to the Company by Acorda since July 2020 related to AMPYRA. The Company paid

Acordathe aggregate $18.3 million in the fourth quarter of 2022. In addition, during the three months ended June 30, 2022, the Company had recorded $3.2 million of royalty revenue related to AMPYRA as the Company believed that it had met the necessary revenue recognition criteria under Topic 606. However, as a result of the arbitration ruling, the Company reversed the $3.2 million as the panel found that the Company was no longer entitled to be paid those royalties. During the three months ended September 30, 2022, the Company recorded both the $18.3 million in repayments and the $3.2 million reversal as reversals of royalty revenue within “Manufacturing and royalty revenue” in the accompanying consolidated statements of operations and comprehensive income (loss). The amounts related to such arbitration ruling were included as part of “Other” within the manufacturing and royalty revenue table above for the year ended December 31, 2022. As a result of the arbitration ruling, the Company has no contractual obligation to manufacture and supply AMPYRA or contractual right to receive future manufacturing or royalty revenue related to AMPYRA. Refer to Note 19, Commitments and Contingent Liabilities within the “Notes to Consolidated Financial Statements” in this Annual Report for information regarding additional legal proceedings related to the arbitration with Acorda.

5. INVESTMENTS

Investments consist of the following:

At December 31, 2023, the Company reviewed its investment portfolio to assess whether the unrealized losses on its available-for-sale investments were temporary. Investments with unrealized losses consisted primarily of corporate debt securities and debt securities issued and backed by U.S. agencies and the U.S. government. At December 31, 2023,97 of the Company’s 231 investment securities were in an unrealized loss position and had an aggregate estimated fair value of $135.0 million. Approximately 36% and

61% of the Company’s investment securities at December 31, 2023 were in corporate debt securities, with a minimum rating of A2 (Moody’s)/A (Standard and Poor’s), and debt securities issued by the U.S. government or its agencies, respectively. The primary reason for the unrealized losses in the Company’s investment portfolio is that its investments are fixed-rate securities acquired in a rising interest rate environment. In making the determination whether the decline in fair value of these securities was temporary, the Company evaluated whether it intended to sell the security and whether it was more likely than not that the Company would be required to sell the security before recovering its amortized cost basis. The Company has the intent and ability to hold these investments until recovery, which may be at maturity.

Realized gains and losses on the sales and maturities of investments, which were identified using the specific identification method, were as follows:

The Company’s available-for-sale and held-to-maturity securities at December 31, 2023 had contractual maturities in the following periods:

6. FAIR VALUE

The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis and indicates the fair value hierarchy and the valuation techniques the Company utilized to determine such fair value:

The Company transfers its financial assets and liabilities, measured at fair value on a recurring basis, between the fair value hierarchies at the end of each reporting period.

There wereno transfers of any securities between levels during the year ended December 31, 2023. At December 31, 2023, the Company hadno investments with fair values that were determined using Level 3 inputs.

The Company’s investments in U.S. government and agency debt securities, non-U.S. government agency debt securities and corporate debt securities classified as Level 2 within the fair value hierarchy were initially valued at the transaction price and subsequently valued, at the end of each reporting period, utilizing market-observable data. The market-observable data included reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events. The Company validated the prices developed using the market-observable data by obtaining market values from other pricing sources, analyzing pricing data in certain instances and confirming that the relevant markets are active.

In April 2015, the Company sold its Gainesville, GA manufacturing facility, the related manufacturing and royalty revenue associated with certain products manufactured at the facility, and the rights to IV/IM and parenteral forms of Meloxicam to Recro Pharma, Inc. (“Recro”) and Recro Gainesville LLC (such transaction the “Gainesville Transaction”). The Gainesville Transaction included in the purchase price contingent consideration tied to low double digit royalties on net sales of the IV/IM and parenteral forms of Meloxicam and any other product with the same active ingredient as Meloxicam IV/IM that is discovered or identified using certain of the Company’s IP to which Recro was provided a right of use, through license or transfer, pursuant to the Gainesville Transaction (such products, the “Meloxicam Products”), and milestone payments upon the achievement of certain regulatory and sales milestones related to the Meloxicam Products.

In November 2019, Recro Pharma, Inc. (“Recro”) spun out its acute care segment to Baudax Bio, Inc. (“Baudax”), a publicly-traded pharmaceutical company. As part of this transaction, Recro’s obligations to pay certain contingent consideration from the Gainesville Transaction were assigned and/or transferred to Baudax.

In Baudax’s Quarterly Report on Form 10-Q for the period ended September 30, 2022, Baudax continued to include disclosures regarding its ability to continue as a going concern, which first appeared in its Annual Report on Form 10-K for the period ended December 31, 2021. In March 2022, Baudax reduced its workforce by approximately 80%, which was designed to reduce its operational expenses and conserve its cash resources. In light of Baudax’s disclosures and the fact that, as of September 30, 2022, Baudax had only paid $1.2 million of the $6.4 million that was due to the Company in March 2022, the Company determined, during the three months ended September 30, 2022, that it was unlikely to collect any further proceeds under this arrangement and reduced the fair value of the contingent consideration to zero within “Change in the fair value of contingent consideration”. In addition, during the three months ended September 30, 2022, the Company determined that certain construction in progress related to the manufacture of ANJESO® had no future value. See Note 8, Property, Plant and Equipment, within the “Notes to Consolidated Financial Statements” in this Annual Report for details related to such construction in progress.

In December 2022, Baudax announced that it would discontinue the sale of ANJESO and the U.S. Food and Drug Administration (“FDA”) acknowledged the discontinuation of sale of ANJESO via listing in the Orange Book.

The estimated fair value of the Company’s long-term debt under the 2026 Term Loans (as defined in Note 12, Long-Term Debt within these “Notes to Consolidated Financial Statements” in this Annual Report), which was based on quoted market price indications (Level 2 in the fair value hierarchy) and which may not be representative of actual values that could have been, or will be, realized in the future, was $291.0 million and $278.9 million at December 31, 2023 and 2022, respectively.

7. INVENTORY

Inventory consists of the following:

(1)

In connection with the sale of the Athlone Facility, certain of the Company’s property, plant and equipment has been classified as “Assets held for sale” in the accompanying consolidated balance sheets at December 31, 2023 and 2022. In addition, certain prior period amounts have been retrospectively adjusted to reflect the effects of the Separation and classified as “Assets held for discontinued operations” in the accompanying consolidated balance sheet at December 31, 2022.

Depreciation expense was $25.7 million, $26.3 million and $23.3 millionfor the years ended December 31, 2023, 2022 and 2021, respectively. Also, during the years ended December 31, 2023, 2022 and 2021, the Company wrote off furniture, fixtures and equipment that had an approximate carrying value of $1.7 million,$0.5 million and $0.1 million, respectively, at the time of disposition.

Amounts included as construction in progress in the consolidated balance sheets primarily include capital expenditures at the Company’s manufacturing facility in Wilmington, Ohio. The Company continues to evaluate its manufacturing capacity based on expectations of demand for its products and will continue to record such amounts within construction in progress until such time as the underlying assets are placed into service. The Company expects that approximately $30.6 million of construction in progress will be placed into service during 2024. The Company continues to periodically evaluate whether facts and circumstances indicate that the carrying value of its long-lived assets to be held and used may not be recoverable.

In September 2022, the Company determined that $8.7 million of its construction in progress that related to the manufacture of ANJESO had no future value. The Company had previously received $6.4 million from Baudax related to such equipment which it had recorded as contract liabilities within “Other long-term liabilities” in the accompanying consolidated balance sheets and the net amount of $2.3 million was written off through “other (expense) income, net” in the accompanying consolidated statements of operations and comprehensive income (loss) during the year ended December 31, 2022.

In December 2023, the Company determined that $2.9 million of its construction in progress at its Wilmington, Ohio manufacturing facility had no future value and was written off through “cost of goods manufactured and sold” in the accompanying consolidated statements of operations and comprehensive income (loss) during the year ended December 31, 2023.

(1)

In connection with the sale of the Athlone Facility, certain of the Company’s property, plant and equipment has been classified as “Assets held for sale” in the accompanying consolidated balance sheets at December 31, 2023 and 2022. In addition, certain prior period amounts have been retrospectively adjusted to reflect the effects of the Separation and classified as “Assets held for discontinued operations” in the accompanying consolidated balance sheet at December 31, 2022.

The Company’s finite-lived intangible assets consist of collaborative agreements and the NanoCrystal and oral controlled release technologies acquired as part of the EDT acquisition. The Company recorded $35.7 million, $36.4 million and $38.1 million of amortization expense related to its finite-lived intangible assets during the years ended December 31, 2023, 2022 and 2021, respectively. The Company’s intangible assets included within its consolidated balance sheets at December 31, 2023 are expected to be fully amortized in the year ending December 31, 2024.

The Company performed its annual goodwill impairment test as of October 31, 2023. The Company performed a quantitative impairment test and based on the weight of all available evidence, determined that the fair value of the reporting unit exceeded its carrying value. As part of the assessment performed as of October 31, 2023, it was determined that a portion of the Company’s goodwill should be allocated to Mural, as a portion of the IP that transferred to Mural was owned by the reporting unit to which the Company’s goodwill was assigned. In connection with the completion of the Separation, the Company recorded a reduction in goodwill of $7.8 million in the accompanying consolidated balance sheet.

In addition, in connection with the planned sale of the Athlone Facility, the Company reviewed FASB ASC 805, Business Combinations and determined that the Athlone Facility constitutes a business and, accordingly, $2.0 million of the Company’s goodwill was allocated to the Athlone Facility and is classified as “Assets held for sale” within the consolidated balance sheets as of December 31, 2023 and 2022.

10. LEASES

All of the Company’s leases are accounted for as operating leases. The Company leases approximately 231,000 square feet of office and laboratory space located at 900 Winter Street in Waltham, Massachusetts (the “900 Winter Street Lease”). The initial term of the lease commenced on January 20, 2020, expires in 2035 and includes an option toextendthe term for an additionalten-year period.

On November 13, 2023, in connection with the Separation, Alkermes US and Mural US entered into an assignment and assumption of lease agreement (the “Assignment”), pursuant to which Alkermes US assigned to Mural US an operating lease for approximately 180,000 square feet of corporate office space, administrative areas and laboratories located at 852 Winter Street in Waltham, Massachusetts (the “852 Winter Street Lease”). Under the terms of the Assignment, Mural US assumed all of Alkermes US’ obligations under the 852 Winter Street Lease. In accordance with FASB ASC 842, Leases, as the Company can no longer access or direct the use of the asset following the Assignment, the 852 Winter Street Lease no longer meets the definition of a lease for the Company. On November 15, 2023, the effective date of the Assignment, the Company reduced its right-of-use asset and lease liability by $14.5 million and $15.4 million, respectively in the accompanying consolidated balance sheet.

In December 2022, the Company exercised an early payment option included within the terms of the 900 Winter Street Lease. The election of such early payment option resulted in a remeasurement of the remaining lease liability and right-of-use asset as of the remeasurement date of December 1, 2022 of $12.8 million. Subsequently, the Company made the early lease payment of $15.3 million in December 2022. As of December 31, 2022, the remeasurement and subsequent payment resulted in an increase in the right-of-use asset of $12.8 million and a net decrease in the lease liability of $2.5 million.

At December 31, 2023 and 2022, the operating leases held by the Company had a weighted average incremental borrowing rate of 4.4% and 5.5%, respectively, and a weighted average remaining lease term of 8.7 years and 9.6 years, respectively. During the years ended December 31, 2023, 2022 and 2021, cash paid for amounts included for the measurement of lease liabilities was $10.3 million, $27.0 million and $11.8 million, respectively. The Company recorded operating lease expense of $10.2 million, $10.7 million and $11.3 million for the years ended December 31, 2023, 2022 and 2021, respectively.

13. EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per ordinary share from continuing operations is calculated based upon net income (loss) from continuing operations available to holders of ordinary shares divided by the weighted average number of ordinary shares outstanding. Basic loss per ordinary share from discontinued operations, is calculated based upon net loss from discontinued operations available to holders of ordinary shares, divided by the weighted average number of ordinary shares outstanding. For the calculation of diluted earnings (loss) per ordinary share from continuing operations and discontinuing operations, the Company utilizes the treasury stock method and adjusts the weighted average number of ordinary shares outstanding for the potential dilutive effect of outstanding ordinary share equivalents such as stock options and RSUs.

(1)

The following potential ordinary share equivalents were not included in the net loss per share calculation because the effect would have been anti-dilutive:

The timing and amount of any share repurchases under the 2024 Repurchase Program will be based on a variety of factors, including but not limited to ongoing assessments of the Company’s capital needs, alternative investment opportunities, the market price of the Company’s ordinary shares and general market conditions. The 2024 Repurchase Program has no set expiration date and may be suspended or discontinued at any time. The 2024 Repurchase Program terminates, and supersedes in its entirety, the Company’s prior share repurchase program authorized by its board of directors in September 2011 (the “Prior Repurchase Program”) under which the Company has purchased a total of 8,866,342 ordinary shares at a cost of $114.0 million. During the years ended December 31, 2023, 2022 and 2021 the Company didnot purchase any ordinary shares under the Prior Repurchase Program.

15. SHARE-BASED COMPENSATION

Share-Based Compensation Expense

The following table presents share-based compensation expense from continuing and discontinued operations included in the Company’s consolidated statements of operations and comprehensive income (loss):

During the years ended December 31, 2023, 2022 and 2021, $3.2 million, $3.3 million and $2.3 million, respectively, of share-based compensation expense was capitalized and recorded as “Inventory” in the accompanying consolidated balance sheets.

Share-Based Compensation Plans

The Company hasone share-based compensation plan pursuant to which awards are currently being made: the 2018 Stock Option and Incentive Plan, as amended (the “2018 Plan”). The Company hastwo share-based compensation plans pursuant to which outstanding awards have been made, but from which no further awards can or will be made: the Alkermes plc Amended and Restated 2008 Stock Option and Incentive Plan, as amended, (the “2008 Plan”) and the Alkermes plc 2011 Stock Option and Incentive Plan, as amended (the “2011 Plan,” and together with the 2018 Plan and the 2008 Plan, the “the Alkermes Stock Option and Incentive Plans”). Effective May 20, 2020, the 2018 Plan was amended such that any shares underlying any outstanding awards granted under the 2011 Plan or the 2008 Plan that are forfeited, canceled, repurchased or otherwise terminated (other than by exercise) from and after such date will become available for issuance pursuant to the 2018 Plan, notwithstanding anything to the contrary in the terms of the 2011 Plan or the 2008 Plan.

The 2018 Plan allows for the issuance of non-qualified and incentive stock options, restricted stock, restricted stock unit awards, cash-based awards and performance shares to employees, officers and directors of, and consultants to, the Company in such amounts and with such terms and conditions as may be determined by the compensation committee of the Company’s board of directors, subject to the provisions of the 2018 Plan, as applicable.

On June 29, 2023, the Company’s shareholders approved an amended version of the Alkermes plc 2018 Stock Option and Incentive Plan that served to, among other things, increase the number of ordinary shares authorized for issuance thereunder by 6.5 million. At December 31, 2023, there were 15.1 million ordinary shares available for issuance in the aggregate under the 2018 Plan. The 2018 Plan provides that awards other than stock options will be counted against the total number of shares available under the plan in a 1.8-to-1 ratio.

In connection with the Separation and in accordance with the provisions of the Alkermes Stock Option and Incentive Plans, the Company adjusted outstanding equity awards as described in Note 2, Significant Accounting Policies within these “Notes to consolidated financial statements” in this Annual Report, and specifically the section entitled “Conversion and Modification of Equity Awards Outstanding at Separation Date”. The incremental number of ordinary shares underlying each award that was outstanding immediately prior to the Separation is included as “Conversion Reissuance” in each of the associated tables below.

Stock Options

A summary of stock option activity is presented in the following table:

The weighted average grant date fair value of stock options granted during the years ended December 31, 2023, 2022 and 2021 was $13.74, $12.62 and $10.09, respectively. The aggregate intrinsic value of stock options exercised during the years ended December 31, 2023, 2022 and 2021 was $6.0 million, $11.6 million and $8.3 million, respectively.

At December 31, 2023, there were 6.9 million stock options expected to vest, with a weighted average exercise price of $24.46 per share, a weighted average contractual remaining life of 8.0 years and an aggregate intrinsic value of $24.6 million. At December 31, 2023, the aggregate intrinsic value of stock options exercisable was $29.4 million with a weighted average remaining contractual term of 4.5 years. The number of stock options expected to vest was determined by applying the pre-vesting forfeiture rate to the total number of outstanding options. The intrinsic value of a stock option is the amount by which the market value of the underlying shares exceeds the exercise price of the stock option.

At December 31, 2023, there was $33.0 million of unrecognized share-based compensation expense related to unvested stock options, which is expected to be recognized over a weighted average period of 1.9 years.

Time-Based Restricted Stock Unit Awards

A summary of time-based RSU activity is presented in the following table:

The weighted average grant date fair values of time-vesting RSUs granted during the years ended December 31, 2023, 2022 and 2021 were $27.65, $25.27 and $20.83, respectively. The total fair value of time-vesting RSUs that vested during the years ended December 31, 2023, 2022 and 2021, was $63.0 million, $54.3 million and $56.3 million, respectively.

At December 31, 2023, there was $55.4 million of total unrecognized share-based compensation expense related to unvested time-vesting RSUs, which will be recognized over a weighted average remaining contractual term of 1.9 years.

Performance-Based Restricted Stock Unit Awards

In February 2023, 2022 and 2021, the compensation committee of the Company’s board of directors approved awards of performance-based RSUs to employees of the Company at the Senior Vice President level and above, in each case subject to vesting based on the achievement of certain financial, commercial and/or R&D performance criteria to be assessed over a performance period ofthree years from the date of the grant, and subject, at the end of such three-year performance period, to upward or downward adjustment based on a market condition tied to relative share price performance over the three-year performance period.

A summary of performance-based RSU activity is presented in the following table:

The weighted average grant date fair values of performance-based RSUs granted during the years ended December 31, 2023, 2022 and 2021 were $29.91, $30.73 and $23.09, respectively. The total fair value of performance-based RSUs that vested during the years ended December 31, 2023, 2022 and 2021 were $5.9 million, none and $4.2 million, respectively. At December 31, 2023, there was $2.5 million of unrecognized share-based compensation expense related to performance-based RSUs granted in February 2022 and 2023, which would be recognized in accordance with the terms of the awards when the Company deems it probable that the performance criteria will be met.

The Company has additional unrecognized share-based compensation expense related to performance-based RSUs that were granted in February 2021. As of December 31, 2023, the financial performance criteria for these awards were deemed not probable of being achieved. On February 8, 2024, the compensation committee of the Company’s board of directors determined that the Company partially achieved the financial performance criteria. This was considered a modification in accordance with FASB ASC 718, Compensation—Stock Compensation and resulted in a modification charge of approximately $6.8 million. On February 8, 2024, the compensation committee of the Company’s board of directors also determined that the Company achieved the pipeline performance criteria for these awards, resulting in a $2.6 million incremental share-based compensation expense, as it was deemed such pipeline performance criteria had been met. The share-based compensation expense related to these achievements will be recognized in 2024.

16. COLLABORATIVE ARRANGEMENTS

The Company has entered into several collaborative arrangements to develop and commercialize products and, in connection with such arrangements, to access technologies, financial, marketing, manufacturing and other resources. Refer to the “Patents and Proprietary Rights” section in “Item 1— Business” of this Annual Report for information with respect to IP protection for these products. The collaboration revenue the Company has earned in the years ended December 31, 2023, 2022 and 2021 is summarized in Note 4, Revenue from Contracts with Customers within the notes to the consolidated financial statements in this Annual Report.

The Company’s significant collaborative arrangements are described below:

Janssen

Under an exclusive license agreement with Janssen, the Company provided Janssen with rights to, and know-how, training and technical assistance in respect of, the Company’s small particle pharmaceutical compound technology, known as NanoCrystal technology, which was used to develop the long-acting INVEGA products, and the Company received milestone payments from Janssen upon the achievement of certain development goals from Janssen; there are no further milestones to be earned under this agreement. The agreement also provides for tiered royalty payments, which consist of a patent royalty and a know-how royalty, both of which are determined on a country-by-country basis. The patent royalty, which equals 1.5% of net sales, is payable in each country until the expiration of the last of the patents claiming the product in such country. The know-how royalty is a tiered royalty of 3.5%,5.5% and 7.5% on aggregate worldwide net sales of below $250 million, between $250 million and $500 million, and greater than $500 million, respectively. The know-how royalty rate resets to 3.5% at the beginning of each calendar year and is payable until 15 years from first commercial sale of a product in each individual country, subject to expiry of the agreement. These royalty payments may be reduced in any country based on patent litigation or on competing products achieving certain minimum sales thresholds. The license agreement, unless earlier terminated, terminates upon the expiration of the last of the patents subject to the agreement. After expiration, Janssen retains a non-exclusive, royalty-free license to develop, manufacture and commercialize the products, subject to certain surviving obligations. Janssen may terminate the license agreement in whole or in part upon three months’ notice to the Company. The Company and Janssen have the right to terminate the agreement upon a material breach of the other party, which is not cured within a certain time period, or upon the other party’s bankruptcy or insolvency.

In November 2021, the Company received notice from Janssen of partial termination of the license agreement, following which Janssen ceased paying the Company royalties related to U.S. sales of INVEGA SUSTENNA, INVEGA TRINZA and INVEGA HAFYERA. In April 2022, the Company commenced binding arbitration proceedings related to, among other things, Janssen’s partial termination of this license agreement and Janssen’s royalty and other obligations under the agreement. In May 2023, the Tribunal in the arbitration proceedings issued a Final Award that served to reinstate the Janssen royalties and required payment by Janssen of back royalties and interest for amounts owed but not yet paid since the effective date of the partial termination. The Final Award also provided, among other things, that the Company was entitled to royalty revenues from Janssen related to net sales of INVEGA SUSTENNA through August 20, 2024, INVEGA TRINZA through the second quarter of 2030 (but no later than May 2030 when the license agreement expires) and INVEGA HAFYERA through May 2030 (when the license agreement expires).

Under a product development agreement, the Company collaborated with Janssen on the development of RISPERDAL CONSTA. Under the development agreement, Janssen provided funding to the Company for the development of RISPERDAL CONSTA and Janssen is responsible for securing all necessary regulatory approvals for the product.

Undertwo license agreements, the Company granted Janssen and an affiliate of Janssen exclusive worldwide licenses to use and sell RISPERDAL CONSTA. Under its license agreements with Janssen, the Company receives royalty payments equal to 2.5% of Janssen’s end-market net sales of RISPERDAL CONSTA in each country where the license is in effect based on the quarter when the product is sold by Janssen. This royalty may be reduced in any country based on lack of patent coverage and significant competition from generic versions of the product. Janssen can terminate the license agreements upon 30 days’ prior written notice to the Company. Either party may terminate the license agreements by written notice following a breach which continues for 90 days after the delivery of written notice thereof or upon the other party’s insolvency. The licenses granted to Janssen expire on a country-by-country basis upon the later of: (i) the expiration of the last patent claiming the product in such country; or (ii)15 years after the date of the first commercial sale of the product in such country, provided that in no event will the license granted to Janssen expire later than the twentieth anniversary of the first commercial sale of the product in each such country, with the exception of Canada, France, Germany, Italy, Japan, Spain and the United Kingdom, in each case where the fifteen-year minimum shall pertain regardless. After expiration, Janssen retains a non-exclusive, royalty-free license to manufacture, use and sell RISPERDAL CONSTA.

The Company exclusively manufactures RISPERDAL CONSTA at its Wilmington, Ohio facility for commercial sale. Under its manufacturing and supply agreement with Janssen, the Company records manufacturing revenues when product is fully manufactured and approved for shipment by both Janssen and the Company. Revenue is based on a percentage of Janssen’s net unit sales price for RISPERDAL CONSTA for the applicable calendar year. This percentage is determined based on Janssen’s unit demand for such calendar year and varies based on the volume of units shipped, with a minimum manufacturing fee of 7.5%. Either party may terminate the manufacturing and supply agreement upon a material breach by the other party, which is not resolved within 60 days after receipt of a written notice specifying the material breach or upon written notice in the event of the other party’s insolvency or bankruptcy. Janssen may terminate the agreement uponsix months’ written notice to the Company. In the event that Janssen terminates the manufacturing and supply agreement without terminating the license agreements, the royalty rate payable to the Company on Janssen’s net sales of RISPERDAL CONSTA would increase from 2.5% to 5.0%.

Biogen

Under a license and collaboration agreement with Biogen, the Company granted Biogen a worldwide, exclusive, sublicensable license to develop, manufacture and commercialize VUMERITY and other products covered by patents licensed to Biogen under the agreement.

Under this license and collaboration agreement, the Company received an upfront cash payment and milestone payments related to the achievement of certain milestones, including FDA approval of the NDA for VUMERITY and amendment of the license and collaboration agreement. The Company is also eligible to receive additional payments upon achievement of certain milestones, including milestones relating to the first two products, other than VUMERITY, covered by patents licensed to Biogen under the license and collaboration agreement.

In addition, the Company receives a 15% royalty on worldwide net sales of VUMERITY, subject to increases for VUMERITY manufactured and/or packaged by Biogen or its designees, and subject to, under certain circumstances, minimum annual payments for the first five years following FDA approval of VUMERITY. The Company is also entitled to receive royalties on net sales of products other than VUMERITY covered by patents licensed to Biogen under the license and collaboration agreement, at tiered royalty rates calculated as percentages of net sales ranging from high-single digits to sub-teen double digits. All royalties are payable on a product-by-product and country-by-country basis until the later of (i) the last-to-expire patent right covering the applicable product in the applicable country and (ii) a specified period of time from the first commercial sale of the applicable product in the applicable country. Royalties for all products and the minimum annual payments for VUMERITY are subject to customary reductions, as set forth in the license and collaboration agreement.

Under the license and collaboration agreement, Biogen appointed the Company as the toll manufacturer of clinical and commercial supplies of VUMERITY, subject to Biogen’s right to manufacture or have manufactured commercial supplies as a back-up manufacturer and subject to good faith agreement by the parties on the terms of such manufacturing arrangements. In October 2019, the Company entered into a commercial supply agreement with Biogen for the commercial supply of VUMERITY, an amendment to such commercial supply agreement and an amendment to the license and collaboration agreement with Biogen, pursuant to which Biogen has elected to conduct a technology transfer and, following an agreed transition period, assume responsibility for the manufacture (itself or through a designee) of clinical supplies of VUMERITY and up to 100% of commercial supplies of VUMERITY in exchange for an increase in the royalty rate to be paid by Biogen to the Company on net sales of that portion of product that is manufactured by Biogen or its designee.

Unless earlier terminated, the license and collaboration agreement will remain in effect until the expiry of all royalty obligations. Biogen has the right to terminate the license and collaboration agreement at will, on a product-by-product basis or in its entirety upon 180 days’ prior notice to the Company. Either party has the right to terminate the license and collaboration agreement following any governmental prohibition of the transactions effected by the agreement, or in connection with an insolvency event involving the other party. Upon termination of the license and collaboration agreement by either party, then, at the Company’s request, the VUMERITY program will revert to the Company.

17. INCOME TAXES

The Company’s (benefit) provision for income taxes from continuing operations consists of the following:

(1)

The income tax benefit in 2023 was primarily due to the partial release of the valuation allowance maintained against certain Irish deferred tax assets, partially offset by taxes on income earned in the U.S. and Ireland. The income tax provisions in 2022 and 2021 were primarily due to U.S. federal and state taxes on income earned in the U.S. and the tax impact of employee equity activity.

In December 2023, the IRS issued Notice 2024-12 that provided clarity on the application of Section 174. On this basis, the Company adjusted its estimate of expenses that should be capitalized and amortized, resulting in lower taxable income and an elimination of the foreign derived intangible income (“FDII”) deduction for the year ended December 31, 2023.

The income tax benefit associated with the Company’s oncology business, and the tax impact of the Separation, are discussed in further detail in Note 3, Discontinued Operations, in these “Notes to Consolidated Financial Statements” in this Annual Report. The tax benefits included within discontinued operations were $1.4 million, $11.1 million, and $2.5 million for the years ended December 31, 2023, 2022, and 2021, respectively.

No provision for income tax has been provided on undistributed earnings of the Company’s foreign subsidiaries because such earnings are indefinitely reinvested in the foreign operations. Cumulative unremitted earnings of U.S. subsidiaries totaled approximately $797.0 million at December 31, 2023. In the event of a repatriation of those earnings in the form of dividends or otherwise, the Company may be liable for income taxes, subject to adjustment, if any, for foreign tax credits and foreign withholding taxes payable to foreign tax authorities. The Company estimates that approximately $70.8 million of income taxes would be payable on the repatriation of the unremitted earnings to Ireland.

The distribution of the Company’s income (loss) before the (benefit) provision for income taxes by geographical area consists of the following:

(1)

The components of the Company’s net deferred tax assets consist of the following:

(1)

The activity in the valuation allowance associated with deferred taxes consists of the following:

(1)

Inclusive of continuing and discontinued operations for all periods other than the balance at December 31, 2023.

(2)

(Additions) reductions represent continuing and discontinued operations. The reduction during the year ended December 31, 2023 primarily relates to the partial release of the valuation allowance maintained against certain Irish net deferred tax assets. The (additions) reductions in 2022 and 2021 relate primarily to Irish net operating losses (“NOLs”).

The Company regularly assesses the need for a valuation allowance against its deferred tax assets. In making such assessment, the Company considers both positive and negative evidence related to the likelihood of realization of the deferred tax assets to determine, based on the weight of available evidence, whether it is more-likely-than-not that some or all of the deferred tax assets will not be realized. During the year ended December 31, 2023, the Company: (i) achieved a favorable outcome in its arbitration with Janssen (as described in Note 4, Revenue from Contracts with Customers in these “Notes to Consolidated Financial Statements” in this Annual Report); (ii) successfully completed the Separation; and (iii) recorded significant pre-tax income due to multiple factors, including the growth of its proprietary revenues and items (i) and (ii) above. As a result, the Company’s main operating subsidiary in Ireland recorded cumulative income during the year ended December 31, 2023 and the three-year period ended December 31, 2023. On this basis and other positive factors (such as anticipated future earnings) and negative factors (such as the potential decrease in certain manufacturing and royalty revenues), the Company has concluded that it is more-likely-than-not that certain Irish deferred tax assets will be realized. Of the $271.5 million valuation allowance maintained as of December 31, 2022, the Company released $143.9 million during the year ended December 31, 2023. At December 31, 2023, the Company maintained a valuation allowance of $27.3 million against certain U.S. state deferred tax assets and $102.0 million against certain Irish deferred tax assets, as the Company has determined that it is more-likely-than-not that these deferred tax assets will not be realized and some may be abandoned.

If the Company incurs losses in the U.S. or in Ireland in the future, the evaluation of the recoverability of the deferred tax assets could change and a valuation allowance against such deferred tax assets may be required in part or in whole. The Company will continue to monitor the need for a valuation allowance against its deferred tax assets on a quarterly basis.

As of December 31, 2023, the Company had $1.3 billion of Irish NOL carryforwards, $14.6 million of U.S. federal NOL carryforwards, $43.2 million of state NOL carryforwards, $9.7 million of federal R&D credits and $31.0 million of state tax credits which will either expire on various dates through 2043 or can be carried forward indefinitely. These loss and credit carryforwards are available to reduce certain future Irish and foreign taxable income and tax. These loss and credit carryforwards are subject to review and possible adjustment by the appropriate taxing authorities. These loss and credit carryforwards, which may be utilized in a future period, may be subject to limitations based upon changes in the ownership of the Company’s ordinary shares. Included within these loss and credit carryforwards are $14.6 million of U.S. federal NOL carryforwards and $6.3 million of state NOL carryforwards, acquired as part of the acquisition of Rodin Therapeutics, Inc. (“Rodin”), each of which are subject to a $0.5 million annual limitation.

A reconciliation of the Company’s statutory tax rate to its effective tax rate is as follows:

(1)

(2)

Represents income or losses of U.S. subsidiaries, subject to tax at a rate other than the Irish statutory rate.

(3)

Intercompany amounts include cross-territory eliminations, the pre-tax effect of which has been eliminated in arriving at the Company's consolidated income (loss) before taxes from continuing operations. In 2023, this included a tax benefit of $15.7 million related to the intercompany transfer of inventory that was owned by the Company at December 31, 2023.

(4)

Represents income or losses of Irish companies subject to tax at a rate other than the Irish statutory rate.

(5)

Represents the tax effect of the research and development expense recorded in connection with the acquisition of Rodin.

(6)

Other permanent items include, but are not limited to, non-deductible meals and entertainment expenses and non-deductible compensation of senior officers of the Company.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

The unrecognized tax benefits at December 31, 2023, if recognized, would affect the Company’s effective tax rate. The Company does not anticipate that the amount of existing unrecognized tax benefits will materially increase or decrease within the next 12 months. The Company has elected to include interest and penalties related to uncertain tax positions as a component of its provision for taxes. For the years ended December 31, 2023, 2022 and 2021, the Company’s accrued interest and penalties related to uncertain tax positions were not material.

The Company’s major taxing jurisdictions include Ireland and the U.S. (federal and state). These jurisdictions have varying statutes of limitations. In the U.S., the 2020 through 2023 fiscal years remain subject to examination by the respective tax authorities, however, some states have longer statutes of limitations and additional fiscal years remain subject to examination. In Ireland, the 2019 through 2023 fiscal years remain subject to examination by the Irish tax authorities. Additionally, because of the Company’s Irish and U.S. loss carryforwards and credit carryforwards, certain tax returns from fiscal years 2002 onward may also be examined. These years generally remain open forthree tofour years after the loss carryforwards and credit carryforwards have been utilized.

The years ended December 31, 2018 and 2017 for Alkermes Finance S.à.r.l, a former indirect subsidiary of Alkermes plc that was liquidated during the year ended December 31, 2020, are currently under examination by the Tax Authorities in Luxembourg (the “LTA”). In February 2023, the Company submitted an appeal to the LTA against the notice of assessment received in 2022 for the year ended December 31, 2017. In the third quarter of 2023, the Company received confirmation that the LTA changed its position and agreed to the originally filed tax return, resulting in the closure of the examination of the year ended December 31, 2017. In connection with the closure, the Company received a refund of approximately €2.2 million from the LTA. As of December 31, 2023, the Company hadnot received a notice of assessment from the LTA in relation to the year ended December 31, 2018.

18. RESTRUCTURING

In July 2023, in conjunction with the Company’s ongoing review of operations and the Separation, the Company implemented a restructuring plan, which included the elimination of approximately 60 positions across the Company (the “Restructuring”). The Company recorded a charge of $6.0 million during the third quarter of 2023 as a result of the Restructuring, which consisted of one-time termination benefits for employee severance, benefits and related costs, all of which are expected to result in cash expenditures, and all of which are expected to be paid within 12 months of the Restructuring. The Company recognized $4.5 million and $1.5 million of this expense in R&D expense and SG&A expense, respectively, in the accompanying consolidated statements of comprehensive income (loss).

Activity related to the Restructuring during the year ended December 31, 2023 was as follows:

19. COMMITMENTS AND CONTINGENT LIABILITIES

Litigation

From time to time, the Company may be subject to legal proceedings and claims in the ordinary course of business. On a quarterly basis, the Company reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim, asserted or unasserted, or legal proceeding is considered probable and the amount can be reasonably estimated, the Company would accrue a liability for the estimated loss. Because of uncertainties related to claims and litigation, accruals are based on the Company’s best estimates, utilizing all available information. On a periodic basis, as additional information becomes available, or based on specific events such as the outcome of litigation or settlement of claims, the Company may reassess the potential liability related to these matters and may revise these estimates, which could result in material adverse adjustments to the Company’s operating results. At December 31, 2023, there wereno potential material losses from claims, asserted or unasserted, or legal proceedings that the Company determined were probable of occurring.

INVEGA SUSTENNA ANDA Litigation

Janssen Pharmaceutica and Janssen Pharmaceuticals, Inc. initiated patent infringement lawsuits in the U.S. District Court for the District of New Jersey (the “NJ District Court”) in January 2018 against Teva Pharmaceuticals USA, Inc. (“Teva”) and Teva Pharmaceuticals Industries, Ltd. (“Teva PI”) (such lawsuit, the “Teva Lawsuit”), in August 2019 against Mylan Laboratories Limited (“Mylan Labs”) and other Mylan entities (the “Mylan Lawsuit”), in December 2019 against Pharmascience, Inc. (“Pharmascience”), Mallinckrodt plc, and SpecGX LLC (the “Pharmascience Lawsuit”), and in February 2022 against Accord Healthcare, Inc., Accord Healthcare, Ltd. and Intas Pharmaceuticals, Ltd (“Accord” and such lawsuit, the “Accord Lawsuit”), and in the U.S. District Court for the District of Delaware (the “DE District Court”) in December 2021 against Tolmar Holding, Inc., Tolmar Pharmaceuticals, Inc., Tolmar Therapeutics, Inc., and Tolmar, Inc. (“Tolmar” and such lawsuit, the “Tolmar Lawsuit”), following the respective filings by each of Teva, Mylan Labs, Pharmascience, Accord and Tolmar of an Abbreviated New Drug Application (“ANDA”) seeking approval from the FDA to market a generic version of INVEGA SUSTENNA before the expiration of U.S. Patent No. 9,439,906. In October 2021, the NJ District Court entered a judgment in favor of the Janssen entities in the Teva Lawsuit. In December 2021, the NJ District Court entered a judgment in favor of the Janssen entities in the Mylan Lawsuit, based on the parties’ prior stipulation to be bound by the judgment in the Teva Lawsuit. The Teva entities and Mylan Labs each filed notices of appeal of their respective judgments with the U.S. Court of Appeals for the Federal Circuit, which were consolidated in January 2022 (the “Teva Appeal”). A trial was held in the Tolmar Lawsuit in October 2023. The Pharmascience Lawsuit and the Accord Lawsuit were administratively terminated in July 2022, pending the outcome of the Teva Appeal. The Company is not a party to any of these proceedings.

INVEGA TRINZA ANDA Litigation

In September 2020, Janssen Pharmaceutica, Janssen Pharmaceuticals, Inc., and Janssen Research & Development, LLC initiated a patent infringement lawsuit in the NJ District Court against Mylan Labs, Mylan, and Mylan Institutional LLC following the filing by Mylan Labs of an ANDA seeking approval from the FDA to market a generic version of INVEGA TRINZA before the expiration of U.S. Patent No. 10,143,693 (the “’693 Patent”). Requested judicial remedies include recovery of litigation costs and injunctive relief. In May 2023, the NJ District Court issued an opinion in favor of the Janssen entities on the issues of infringement and validity of the ’693 Patent and the Mylan entities filed a notice of appeal of the decision. The Company is not a party to this proceeding.

VUMERITY ANDA Litigation

In July 2023, Biogen Inc., Biogen Swiss Manufacturing GmbH and Alkermes Pharma Ireland Limited filed a patent infringement lawsuit in the DE District Court against Zydus Worldwide DMCC, Zydus Pharmaceuticals (USA) Inc. and Zydus Lifesciences Limited (collectively, “Zydus”) following the filing by Zydus of an ANDA seeking approval from the FDA to engage in the commercial manufacture, use or sale of a generic version of VUMERITY (diroximel fumarate) delayed-release capsules for oral use, 231 mg, before expiration of the Company’s U.S. Patent Nos. 8,669,281; 9,090,558; and 10,080,733. The filing of the lawsuit triggered a stay of FDA approval of the ANDA for up to 30 months in accordance with the U.S. Drug Price Competition and Patent Term Restoration Act of 1984 (the “Hatch-Waxman Act”). In October 2023, Zydus filed an answer to the complaint.

Government Matters

The Company has received a subpoena and civil investigative demands from U.S. state and federal governmental authorities for documents related to VIVITROL. The Company is cooperating with the investigations.

Product Liability and Other Legal Proceedings

The Company is involved in litigation and other legal proceedings incidental to its normal business activities, including product liability cases alleging that the FDA-approved VIVITROL labeling was inadequate and caused the users of the product to suffer from opioid overdose and death. The Company intends to vigorously defend itself in these matters.

In addition, in January 2023, Acorda filed a petition with the U.S. District Court for the Southern District of New York (the “NY Southern District Court”) asking the court to confirm in part and modify in part the final arbitral award rendered by an arbitration panel in October 2022 and, as part of the requested modification, seeking an additional approximately $66.0 million in damages. In August 2023, the NY Southern District Court confirmed the final arbitral award and declined to modify the final award to increase the damages awarded thereunder. In September 2023, Acorda filed a notice of appeal of the NY Southern District Court decision to the U.S. Court of Appeals for the Federal Circuit (the “Federal Circuit”), and the Company filed a motion to transfer the appeal to the U.S. Court of Appeals for the Second Circuit. On October 10, 2023, Acorda filed an opposition to such motion. On January 18, 2024, the Federal Circuit denied without prejudice the Company’s motion to transfer the appeal and instructed the parties to brief the jurisdictional question as part of the merits appeal.

While the outcome of any of these proceedings cannot be accurately predicted, the Company does not believe the ultimate resolution of any of these existing proceedings would have a material adverse effect on the Company’s business or financial condition.
