Supernus Pharmaceuticals, Inc.
Notes to Condensed Consolidated Financial Statements (unaudited)
1.    Business Organization
Supernus Pharmaceuticals, Inc. (the Company) is a biopharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases. The Company's diverse neuroscience portfolio includes approved treatments for epilepsy, migraine, attention-deficit hyperactivity disorder (ADHD), hypomobility in Parkinson’s Disease (PD), cervical dystonia, chronic sialorrhea, dyskinesia in PD patients receiving levodopa-based therapy, and drug-induced extrapyramidal reactions in adult patients. The Company is developing a broad range of novel CNS product candidates including new potential treatments for hypomobility in PD, epilepsy, depression, and other CNS disorders.
Commercial Products
Trokendi XR® (topiramate) is the first once-daily extended-release topiramate product indicated for the treatment of epilepsy in patients 6 years of age and older in the United States (U.S.) market. It is also indicated for the prophylaxis of migraine headache in adults and adolescents 12 years and older.
Oxtellar XR® (oxcarbazepine) is indicated as therapy for the treatment of partial onset seizures in patients 6 years of age and older. It is also the first once-daily extended-release oxcarbazepine product indicated for the treatment of epilepsy in the U.S.
Qelbree® (viloxazine extended-release capsules) is a novel non-stimulant product indicated for the treatment of ADHD in adults and pediatric patients 6 years and older. On April 2, 2021, the U.S. Food and Drug Administration (FDA) approved Qelbree for the treatment of ADHD in pediatric patients 6 to 17 years of age. In May 2021, the Company launched Qelbree for pediatric patients in the U.S. On April 29, 2022, the FDA approved Qelbree for treatment of ADHD in adult patients. The Company is expecting to launch Qelbree for adult patients by the end of May 2022.
APOKYN® (apomorphine hydrochloride injection) is a product indicated for the acute, intermittent treatment of hypomobility, "off" episodes ("end-of-dose wearing off" and unpredictable "on/off" episodes) in patients with advanced PD.
MYOBLOC® (rimabotulinumtoxinB injection) is a product indicated for the treatment of cervical dystonia and chronic sialorrhea in adults. It is the only botulinum toxin type B available on the market.
XADAGO® (safinamide) is a once-daily product indicated as adjunctive treatment to levodopa/carbidopa in patients with PD experiencing "off" episodes.
GOCOVRI® (amantadine) extended-release capsules is the first and only FDA approved medicine indicated for the treatment of dyskinesia in patients with PD receiving levodopa-based therapy, with or without concomitant dopaminergic medications, and as an adjunctive treatment to levodopa/carbidopa with PD experiencing "off" episodes.

Adamas Acquisition and Reorganization
On October 10, 2021, the Company entered into an Agreement and Plan of Merger by and among the Company, Adamas Pharmaceuticals, Inc. (Adamas) and Supernus Reef, Inc., a Delaware corporation and a wholly owned subsidiary of the Company (Purchaser) (Adamas Agreement). On November 24, 2021, the Purchaser was merged with and into Adamas (Merger), with Adamas continuing as the surviving corporation in the Merger as a wholly owned subsidiary of the Company (Adamas Acquisition). Adamas holds and markets two established commercial products in its portfolio, GOCOVRI and Osmolex ER, and has royalty rights to Namzaric®. Allergan plc markets and sells Namzaric in the U.S.

In the first quarter of 2022 and subsequent to the Adamas Acquisition, the Company completed a reorganization of the Adamas legal entities in an effort to obtain operational, legal and other benefits that also resulted in certain state tax efficiencies. The legal entities reorganization had no effect on the condensed consolidated financial statements other than certain state tax efficiencies. (See Note 12, Income Taxes.)
COVID-19 Impact
The Company is closely monitoring the impact of the COVID-19 pandemic on all aspects of its business operations and has assessed the impact of the COVID-19 pandemic on its condensed consolidated financial statements as of March 31, 2022.
Since the situation surrounding the COVID-19 pandemic remains fluid and the duration uncertain, the long-term nature and extent of the impacts of the pandemic on the Company's business operations and financial position cannot be reasonably estimated at this time.
2.    Summary of Significant Accounting Policies
Basis of Presentation
The Company’s unaudited condensed consolidated financial statements have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (SEC) for interim financial information. As permitted under Generally Accepted Accounting Principles in the United States (U.S. GAAP), certain notes and other information have been omitted from the interim unaudited condensed consolidated financial statements presented in this Quarterly Report on Form 10-Q. Therefore, these condensed consolidated financial statements should be read in conjunction with the Company’s most recent Annual Report on Form 10-K, for the year ended December 31, 2021, filed with the SEC.
In management’s opinion, the condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows. The results of operations for any interim period are not necessarily indicative of the Company’s future quarterly or annual results.
The Company, which is primarily located in the U.S., operates in one operating segment.
Consolidation
The Company's condensed consolidated financial statements include the accounts of Supernus Pharmaceuticals, Inc. and its wholly owned subsidiaries. These are collectively referred to herein as "Supernus" or "the Company." All significant intercompany transactions and balances have been eliminated in consolidation.
The consolidated financial statements reflect the consolidation of entities in which the Company has a controlling financial interest. In determining whether there is a controlling financial interest, the Company considers if it has a majority of the voting interests of the entity, or if the entity is a variable interest entity (VIE) and if the Company is the primary beneficiary. In determining the primary beneficiary of a VIE, the Company evaluates whether it has both: the power to direct the activities of the VIE that most significantly impact the VIE's economic performance; and the obligation to absorb losses of, or the right to receive benefits from the VIE that could potentially be significant to that VIE. The Company's judgment with respect to its level of influence or control of an entity involves the consideration of various factors, including the form of an ownership interest; representation in the entity's governance; the size of the investment; estimates of future cash flows; the ability to participate in policymaking decisions; and the rights of the other investors to participate in the decision making process, including the right to liquidate the entity, if applicable. If the Company is not the primary beneficiary of the VIE, and an ownership interest is maintained in the entity, the interest is accounted for under the equity or cost methods of accounting, as appropriate.
The Company continuously assesses whether it is the primary beneficiary of a VIE as changes to existing relationships or future transactions may affect its conclusions.

Table of Contents

Use of Estimates
The Company bases its estimates on: historical experience; forecasts; information received from its service providers; information from other sources, including public and proprietary sources; and other assumptions that the Company believes are reasonable under the circumstances. Actual results could differ materially from the Company’s estimates. The Company periodically evaluates the methodologies employed in making its estimates.
The extent to which the COVID-19 pandemic may directly or indirectly impact our business, financial condition and results of operations is highly uncertain and subject to change. As a result, certain of our estimates and assumptions, including the provision for sales deductions, the valuation of the assets acquired and liabilities assumed in the Adamas Acquisition, and the fair values of our financial instruments, require increased judgment and carry a higher degree of variability and volatility that could result in material changes to our estimates in future periods.
Advertising Expense
Advertising expense includes the cost of promotional materials and activities, such as printed materials and digital marketing, marketing programs and speaker programs. The cost of the Company's advertising efforts are expensed as incurred.
The Company incurred approximately $23.9 million and $15.3 million in advertising expense for the three months ended March 31, 2022 and 2021, respectively. These expenses are recorded as a component of Selling, general and administrative expenses in the condensed consolidated statements of earnings.
Recently Issued Accounting Pronouncements
Accounting Pronouncements Adopted
Accounting Standards Update (ASU) 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity - The new standard, issued in August 2020, simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible debt instruments with cash conversion and beneficial conversion features. ASU 2020-06 eliminates requirements to separately account for liability and equity components of such convertible debt instruments and eliminates the ability to use the treasury stock method for calculating diluted earnings per share for convertible instruments whose principal amount may be settled in whole or in part with equity. Instead, ASU 2020-06 requires (i) the entire amount of the security to be presented as a liability on the balance sheet and (ii) application of the “if-converted” method for calculating diluted earnings per share. This new standard also removes certain settlement conditions required for equity contracts to qualify for the derivative scope exception.
The Company adopted the new guidance as of January 1, 2022 using the modified retrospective method of transition which allows for a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As a result, the cumulative effect of the accounting change increased the carrying amount of the convertible notes, net by $20.6 million, increased retained earnings by $40.6 million, reduced additional paid-in capital by $56.2 million, and decreased deferred tax liabilities by $5.0 million as of January 1, 2022. In addition, the Company had an increase of 6.8 million in dilutive shares included in diluted weighted average shares of common stock outstanding for the purposes of calculating diluted earnings per share under the if-converted method.
ASU 2021-10, Government Assistance (Topic 832) - The new standard, issued in November 2021, requires the disclosure of information about transactions with a government that are accounted for by applying a grant or contribution model by analogy. This could include various forms of government assistance, but excludes transactions in the scope of specific US GAAP, such as tax incentives accounted for under Accounting Standards Codification (ASC) 740, Income Taxes. For transactions in the scope of the new standard, information about the nature of the transaction, including significant terms and conditions, as well as the amounts and specific financial statement line items affected by the transaction are required to be disclosed. This guidance is effective for fiscal years beginning after December 15, 2021 on a prospective basis. The adoption of the new standard as of January 1, 2022 did not have a material impact to the financial statements.
New Accounting Pronouncements Not Yet Adopted
ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers - The new standard, issued in October 2021, amended guidance on accounting for contract assets and contract liabilities from contracts with customers in a business combination. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with ASC 606, Revenue from Contracts with Customers, as if the acquiree had

initially applied recognition and measurement in their financial statements. This guidance is effective for fiscal years beginning after December 15, 2022 on a prospective basis. Early adoption is permitted.
3. Acquisition
Adamas Acquisition
On November 24, 2021 (the Closing Date), the Company completed its purchase of all of the outstanding equity of Adamas Pharmaceuticals, Inc., a publicly-held pharmaceutical company (Adamas), pursuant to the Adamas Agreement dated October 10, 2021. On the Closing Date, Adamas owned two marketed products: GOCOVRI (amantadine) extended-release capsules, the first and only U.S. FDA approved medicine indicated for the treatment of both "off" episodes and dyskinesia in patients with PD receiving levodopa-based therapy and as an adjunctive treatment to levodopa/carbidopa in patients with PD experiencing "off" episodes; and OSMOLEX ER (amantadine) extended-release tablets, approved for the treatment of PD and drug-induced extrapyramidal reactions in adult patients. Adamas also owns the right to receive royalties from Allergan plc for sales of Namzaric (memantine hydrochloride extended-release and donepezil hydrochloride) in the U.S.
The Company paid the Adamas shareholders $400.8 million and transferred two non-tradable contingent value rights (CVRs). Each CVR represents the contractual right to receive a contingent payment of $0.50 per share in cash, less any applicable withholding taxes and without interest, upon the achievement of the applicable milestone (each such amount, a Milestone Payment) in accordance with the terms of a Contingent Value Rights Agreement entered into between the Company and American Stock Transfer & Trust Company, LLC, as rights agent, (CVR Agreement). One Milestone Payment is payable (subject to certain terms and conditions) upon the first occurrence of the achievement of aggregate worldwide net sales of GOCOVRI in excess of $150 million during any consecutive 12-month period ending on or before December 31, 2024 (Milestone 2024). Another Milestone Payment is payable (subject to certain terms and conditions) upon the first occurrence of the achievement of aggregate worldwide net sales of GOCOVRI in excess of $225 million during any consecutive 12-month period ending on or before December 31, 2025 (Milestone 2025 and, together with Milestone 2024, the Milestones). Each Milestone may only be achieved once.
In connection with the two CVRs, the Company recorded contingent consideration liabilities of $10.3 million as of the date of the acquisition, to reflect the estimated fair value of the contingent consideration. The estimated fair value of the liabilities were determined using Monte Carlo simulations. The fair value measurement of the contingent consideration liabilities were determined based on significant unobservable inputs and thus represents a Level 3 fair value measurement. The key assumptions considered include the estimated amount and timing of projected cash flows, volatility, estimated discount rates and risk-free interest rate. In each reporting period after the acquisition, the Company will revalue the contingent consideration liabilities and will record increases or decreases in the fair value of the liabilities in its consolidated statements of earnings. Changes in fair value will result from changes in actual and projected milestone achievement, as well as changes to forecasts. The inputs and assumptions may not be observable in the market, but they reflect the assumptions the Company believes would be made by a market participant. The possible outcomes for the contingent consideration range from $0 to $50.9 million on an undiscounted basis.
The acquisition was accounted for as a business combination under the acquisition method of accounting, in accordance with ASC 805, Business Combinations. The excess of the purchase price over the fair value of the net assets acquired was recorded as goodwill. The estimated fair values of the assets acquired and liabilities assumed, including goodwill, have been included in the Company's consolidated financial statements since the acquisition Closing Date.
The Company's accounting for the Adamas Acquisition is preliminary and fair value estimates for the assets acquired and liabilities assumed and the Company's estimates and assumptions are subject to change as the Company obtains additional information for its estimates during the measurement period. During the measurement period, if the Company obtains new information regarding facts and circumstances that existed as of the Closing Date that, if known, would have resulted in revised estimated values of those assets or liabilities, the Company will accordingly revise its estimates of fair values and purchase price allocation. The effect of measurement period adjustments on the estimated fair value elements will be reflected as if the adjustments had been made as of the Closing Date. The impact of all changes that do not qualify as measurement period adjustments will be included in current period earnings.
The Company expects to finalize its purchase price allocation within one year of the Closing Date. In addition, the Company continues to analyze and assess relevant information necessary to determine, recognize and record at fair value the assets acquired and liabilities assumed in the following areas: intangible assets, lease assets and liabilities, tax assets and liabilities, and certain existing or potential reserves, including those for legal or contract-related matters. The activities the Company is currently undertaking include, but are not limited to, the following: review of acquired contracts and other contract-related and legal matters; review and evaluation of the accounting policies, tax positions, and other tax-related matters. Further,
11

Table of Contents

the Company continues to obtain input from third party valuation firms with respect to the fair value of the acquired tangible and intangible assets, and other information necessary to record and measure the assets acquired and liabilities assumed. Accordingly, the preliminary recognition and measurement of assets acquired and liabilities assumed as of the Closing Date are subject to change.
The following table presents the Company's preliminary estimates of the fair value of assets acquired and liabilities assumed as of the Closing Date and subsequent measurement period adjustments recorded (dollars in thousands):

(2) Refinement of the estimate of fair value of the right of use asset associated with the acquired Adamas headquarters lease. Refer to Note 13, Leases.
(3) Represents tax impact of the changes in the initial estimate of the fair value of the right of use asset and changes made to update certain state tax attributes which existed at the opening balance sheet date.
Acquired Inventory
The estimated fair value of the inventory was determined using the comparative sales method, which estimated the expected sales price of the product, reduced by all costs expected to be incurred to complete or dispose of the inventory, as well as a profit on the sale.
Acquired Intangible Assets
The acquired intangible assets include the acquired developed technology and product rights to GOCOVRI and OSMOLEX ER, as well as the right to receive royalties from Allergan plc for sales of Namzaric. The Company determined the estimated fair values for the acquired intangible assets as of the Closing Date using the income approach. This is a valuation technique that provides an estimate of fair value of the assets, based on the market participant's expectations of the cash flows that the assets are forecasted to generate. The cash flows were discounted at a rate commensurate with the level of risk associated with

its projected cash flows. The Company believes the assumptions are representative of those a market participant would use in estimating fair value.
The fair value measurements of the acquired intangible assets were determined based on significant unobservable inputs and thus represent Level 3 fair value measurement. Some of the more significant inputs and assumptions used in the intangible assets valuation includes: the estimated future cash flows from product sales, the timing and projection of costs and expenses, discount rates and tax rates.
Acquired intangible assets consist of developed technology and product rights and are amortized over their estimated useful lives on a straight-line basis. The following table summarizes the preliminary purchase price allocation, and the average remaining useful lives for identifiable intangible assets (dollars in thousands):
Estimated Fair ValueEstimated Useful Life as of Closing Date (in years)
Acquired developed technology and product rights$450,100 
3.1 - 8.1
Goodwill
Goodwill was calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from the other assets acquired that could not be individually identified and separately recognized. Goodwill is primarily attributable to the anticipated cost synergies, additional growth platforms, and an expanded revenue base with the addition of the assets from the Adamas Acquisition. The goodwill is not expected to be deductible for tax purposes.
Acquired Deferred Income Tax Liabilities, net
The deferred income tax liabilities, net relates to the difference between the financial statement carrying amount and the tax basis of acquired intangible assets and inventory, partially offset by acquired net operating loss carryforwards and other temporary differences. The acquired federal and state net operating loss carryforwards is reduced by a valuation allowance for amounts that are not expected to be realizable in the future.
Revenue and Net Earnings of Adamas
The operations of Adamas and its subsidiaries have been included in the Company's consolidated statements of earnings for the period subsequent to the Closing Date.
Pro Forma Information
The following table presents the unaudited pro forma combined financial information for each of the periods presented, as if the Adamas Acquisition had occurred on January 1, 2020 (dollars in thousands):

The unaudited pro forma combined financial information is based on historical financial information and the Company's preliminary allocation of purchase price; therefore, it is subject to subsequent adjustment upon finalization of the purchase price allocation. In order to reflect the occurrence of the acquisition on January 1, 2020, the unaudited pro forma combined financial information reflects the recognition of additional amortization expense on intangible assets and estimated additional cost of products sold related to the inventory step-up adjustment; the estimated reduction in the Company's interest income generated from marketable securities that were liquidated to fund the purchase price of the Adamas Acquisition, and the estimated tax impact of the pro forma adjustments.
The unaudited pro forma combined financial information should not necessarily be considered indicative of the results that would have occurred if the acquisition had been consummated on the assumed completion date, nor are they indicative of future results.

Investment in Navitor
Development Agreement
In April 2020, the Company entered into a development agreement (the Development Agreement) with Navitor Pharmaceuticals, Inc. (Navitor Inc.). The Company can terminate the Development Agreement upon 30 days' notice. Under the terms of the Development Agreement, the Company and Navitor Inc. will jointly conduct a Phase II clinical program for NV-5138 (SPN-820) for treatment-resistant depression. The Company will bear all of the Phase I and Phase II development costs incurred by either party, up to a maximum of $50 million. In addition, the Company will incur certain other research and development support costs. There are certain additional payment amounts which could be incurred by the Company. These costs are contingent upon Navitor Inc. achieving defined development milestones. The Company has an option to acquire or license NV-5138 (SPN-820), for which additional payments would be required.
Equity investment
In addition to entering into the Development Agreement in April 2020, the Company acquired Series D Preferred Shares of Navitor Inc. for $15 million, representing an approximately 13% ownership position in Navitor Inc.
In March 2021, Navitor Inc. underwent a legal restructuring. In the restructuring, Navitor Inc. became a wholly owned subsidiary of a newly formed limited liability company, Navitor Pharmaceuticals LLC (Navitor LLC), and the outstanding shares of stock in Navitor Inc. were exchanged for units of membership in Navitor LLC having equivalent rights and preferences (Navitor Restructuring). As part of the Navitor Restructuring, the Series D Preferred Shares previously held by the Company were exchanged for Series D Preferred Shares in Navitor LLC. In addition, certain assets that did not relate to NV-5138 (SPN-820) were transferred from Navitor Inc. to a newly formed entity that became a separate, wholly owned subsidiary of Navitor LLC.
The Company had determined that Navitor LLC is a VIE. The Company does not consolidate this VIE because the Company lacks the power to direct the activities that most significantly impact Navitor’s economic performance.
Prior to the Navitor Restructuring, the investment was accounted for under the practical expedient allowed for equity securities without readily determinable fair value, which is cost minus impairment plus any changes in observable price changes from an orderly transaction of similar investments in Navitor Inc. Following the legal restructuring and exchange of the preferred shares for member equity units of Navitor LLC, the investment was accounted for under the equity method of accounting due to the Company's ability to exert significant influence over but not control the financial and operating decisions of Navitor LLC. As a result of the change from a cost method investment to an equity method investment, the Company was required to measure its investment initially in accordance with the guidance in ASC 805. The majority of the assets and liabilities recorded in Navitor LLC's financial statements represent working capital items and cash that are being used for research and development purposes and are significantly lower than the Company's investment in Navitor LLC, which created a significant basis difference for the Company's investment in the underlying net assets. The Company determined that substantially all of the fair value of the investment was attributable to a single in-process research and development (IPR&D) asset. As a result, Navitor LLC was not considered a business as defined in ASC 805. In the first quarter of 2021, the $15 million investment, which was previously recorded in Other assets in the condensed consolidated balance sheets, was expensed and recorded in Research and development expense in the condensed consolidated statements of earnings.
The Company records its share of the results of Navitor LLC, a private company, on a quarter lag as the financial information of Navitor LLC is not available on a sufficiently timely basis for the Company to apply the equity method of accounting. In December 2021, Navitor LLC sold one of its subsidiaries and distributed cash to its members in accordance with each member's share of the proceeds from the sale. The Company received $12.9 million in December 2021 from Navitor LLC in connection with this sale. As the Company's policy is to record its share of the results in its equity method investment on a quarter lag as previously indicated, the Company recorded the cash amount received in Other current liabilities in the consolidated balance sheets as of December 31, 2021. In the first quarter of 2022, the Company determined its estimated share of Navitor LLC's year-end 2021 earnings and recorded a gain of $12.9 million in Interest and other income, net in the condensed consolidated statement of earnings.
The maximum exposure to losses related to Navitor LLC is a maximum of approximately $50 million in expense for Phase I and Phase II development of NV-5138 (SPN-820), and the cost of other development and formulation activities provided by the Company.

6.    Fair Value of Financial Measurements
The fair value of an asset or liability represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between unrelated market participants.
The Company reports the fair value of assets and liabilities using a three level measurement hierarchy that prioritizes the inputs used to measure fair value. Fair value hierarchy consists of the following three levels:
Level 1—Valuations based on unadjusted quoted prices in active markets that are accessible at measurement date for identical assets.
Level 2—Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and model-based valuations in which all significant inputs are observable in the market, either directly or indirectly (e.g., interest rates; yield curves).
Level 3—Valuations using significant inputs that are unobservable in the market and inputs that reflect the Company’s own assumptions. These are based on the best information available, including the Company’s own data.
The fair value of the restricted marketable securities which are classified as Level 2 financial assets is recorded in Other assets on the condensed consolidated balance sheets. There were no Level 3 financial assets as of March 31, 2022 or December 31, 2021. There have been no transfers of assets or liabilities into or out of Level 3 of the fair value hierarchy.

The fair value has been estimated based on actual trading information, and quoted prices, both provided by bond traders. As discussed in Note 2, the Company adopted ASU 2020-06 on January 1, 2022 using the modified retrospective method of transition resulting in an increase in the carrying amount of the debt by $20.6 million as of the adoption date. Refer to Note 2, Summary of Significant Accounting Policies, for further discussion of the accounting standard adoption.
7. Contingent Consideration
The Company's contingent consideration liabilities are related to the USWM Acquisition and the Adamas Acquisition.
On June 9, 2020 (the USWM Closing Date), the Company completed its acquisition of all the outstanding equity of USWM Enterprises, LLC (USWM Enterprises) (USWM Acquisition). The USWM Acquisition included potential additional contingent consideration payments of up to $230 million, comprising of $130 million for the achievement of certain SPN-830 regulatory and commercial milestones (regulatory and developmental contingent consideration payments) and up to $100 million related to the future sales performance of the acquired USWM products (sales-based contingent consideration payments). The regulatory and developmental contingent consideration payments include a $25 million milestone due upon the FDA acceptance of the SPN-830 NDA for review. The remaining $105 million are due upon the FDA's regulatory approval and commercial launch of SPN-830. Based on timing of the PDUFA date of SPN-830 NDA, one of the regulatory and developmental milestones which has a time-based mechanism for full or partial achievement will not be achieved. Of the $100 million sales-based contingent consideration, a $35 million milestone due upon achievement of certain U.S. net product sales of APOKYN in 2021 was not achieved. The remaining $65 million relates to the achievement of certain net product sales of the acquired USWM products in 2022 and 2023.

Table of Contents


As mentioned in Note 1, the Company received a notice from the FDA in February 2022 of its acceptance for review of the NDA for SPN-830. As such, the Company made a $25 million regulatory and developmental contingent consideration payment in the first quarter of 2022. This milestone payment is reflected in the condensed consolidated statements of cash flows as a $22.9 million under cash flows from financing activities related to the acquisition date fair value of the contingent consideration liability and a $2.1 million under cash flows from operating activities related to excess of the acquisition date fair value.
As discussed in Note 3, Acquisition, the Adamas Acquisition included payment of two non-tradable contingent value rights (CVRs) each of which represents the contractual right to receive a contingent payment upon the achievement of the applicable aggregate worldwide net product sales of GOCOVRI.
The Company's contingent consideration liabilities are measured at fair value on a recurring basis; i.e., the Monte Carlo simulation for the sales-based milestones, and the income approach for the other milestones. The Company classifies its contingent consideration liabilities as Level 3 fair value measurements based on the significant unobservable inputs used to estimate fair value. These reflect the inputs and assumptions the Company believes would be made by market participants. Changes in any of those inputs together or in isolation may result in significantly lower or higher fair value measurement.
During the measurement period, changes in the fair value of contingent consideration related to the Adamas Acquisition are recorded against goodwill if such changes are related to facts and circumstances that existed at the acquisition date. In each reporting period after the acquisition, the Company remeasures the fair value of contingent consideration liabilities and records in its consolidated statements of earnings the increases or decreases in the fair value of the liabilities. The Company recorded a net expense of $0.7 million due to the change in fair value of the contingent consideration liabilities in the first quarter of 2022. The change in fair value is reported on the condensed consolidated statement of earnings in Contingent consideration expense.
The change in the fair value of contingent consideration was primarily driven by the increase in estimated fair value of regulatory and developmental USWM milestones due to the accretion to the payout amount related to the milestone achieved in the first quarter of 2022. The increase is partially offset by a decrease in the estimated fair value of sales-based Adamas milestones due to changes in market data. The key assumptions considered in estimating the fair value of regulatory and developmental milestones include the estimated probability and timing of milestone achievement, such as the probability and timing of obtaining regulatory approval. The key assumptions considered in estimating the fair value of the Adamas sales-based milestones include the estimated amount and timing of projected cash flows, volatility, estimated discount rates and risk-free interest rate. Refer to Note 3, Acquisition, for further discussion of significant inputs and assumptions used in the valuation of the contingent consideration for the Adamas Acquisition.

Patent defense costs are deferred legal fees incurred in conjunction with defending patents for Oxtellar XR and Trokendi XR. U.S. patents covering Oxtellar XR and Trokendi XR will expire no earlier than 2027. In regards to Trokendi XR, the Company entered into settlement agreements that allow third parties to enter the market by January 1, 2023, or earlier under certain circumstances.
Amortization expense for intangible assets was approximately $20.6 million and $6.0 million, for the three month periods ended March 31, 2022 and 2021, respectively. The increase in expense is primarily due to amortization of the acquired developed technology and product rights from the Adamas Acquisition.
Anticipated annual amortization expense for intangible assets is estimated at $79.8 million in 2023 and 2024, $75.0 million in 2025 and 2026, and $73.2 million in 2027.
9.    Convertible Senior Notes Due 2023
The 0.625% Convertible Senior Notes Due 2023 (2023 Notes), which were issued in March 2018, bear interest at an annual rate of 0.625%, payable semi-annually in arrears on April 1 and October 1 of each year. The 2023 Notes will mature on April 1, 2023, unless earlier converted or repurchased by the Company. The Company may not redeem the 2023 Notes at its option before maturity. The total principal amount of 2023 Notes is $402.5 million.
The 2023 Notes were issued pursuant to an Indenture between the Company and Wilmington Trust, National Association, as trustee. The Indenture includes customary terms and covenants, including certain events of default upon which the 2023 Notes may be due and payable immediately. The Indenture does not contain any financial or operating covenants, or any restrictions on the payment of dividends, the issuance of other indebtedness, or the issuance or repurchase of securities by the Company.
Noteholders may convert their 2023 Notes at their option only in the following circumstances: (1) during any calendar quarter, if the last reported sale price per share of the Company's common stock for at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including the last trading day of the immediately preceding
19

Table of Contents

calendar quarter, exceeds 130% of the conversion price, or a price of approximately $77.13 per share on such trading day; (2) during the five consecutive business days immediately after any 10 consecutive trading day period (such 10 consecutive trading day period, the "measurement period") in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Company's common stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Company's common stock, as specified in the Indenture; and (4) at any time from and including October 1, 2022, until the close of business on the second scheduled trading day immediately before the maturity date.
At its election, the Company will settle conversions by paying or delivering, as applicable, cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock, based on the applicable conversion rate. The initial conversion rate is 16.8545 shares per $1,000 principal amount of the 2023 Notes, which represents an initial conversion price of approximately $59.33 per share, and is subject to adjustment as specified in the Indenture. In the event of conversion, if converted in cash, the holders would forgo all future interest payments, any unpaid accrued interest, and the possibility of further stock price appreciation.
If a “make-whole fundamental change,” as defined in the Indenture occurs, then the Company will in certain circumstances increase the conversion rate for a specified period of time. If a “fundamental change,” as defined in the Indenture occurs, then noteholders may require the Company to repurchase their 2023 Notes at a cash repurchase price equal to the principal amount of the 2023 Notes to be repurchased, plus accrued and unpaid interest, if any.
Contemporaneous with the issuance of the 2023 Notes, the Company also entered into separate privately negotiated convertible note hedge transactions (collectively, the Convertible Note Hedge Transactions) with each of the call spread counterparties. The Company issued 402,500 convertible note hedge options. In the event that shares or cash are deliverable to holders of the 2023 Notes upon conversion at limits defined in the Indenture, counterparties to the convertible note hedges will be required to deliver up to approximately 6.8 million shares of the Company’s common stock, or to pay cash to the Company in a similar amount as the value that the Company delivers to the holders of the 2023 Notes, based on a conversion price of $59.33 per share.
Concurrently with entering into the Convertible Note Hedge Transactions, the Company also entered into separate privately negotiated warrant transactions (collectively, the Warrant Transactions) with each of the call spread counterparties. The Company issued a total of 6,783,939 warrants. The warrants entitle the holder to one share per warrant. The strike price of the Warrant Transactions will initially be $80.91 per share of the Company’s common stock, and is subject to adjustment.
The Convertible Note Hedge Transactions are expected to reduce the potential dilution of the Company’s common stock upon conversion of the 2023 Notes, and/or offset any potential cash payments the Company is required to make in excess of the principal amount of converted 2023 Notes, as the case may be.
The Warrant Transactions were intended to partially offset the cost to the Company of the purchased Convertible Note Hedge Transactions; however, the Warrant Transactions could have a dilutive effect with respect to the Company’s common stock, to the extent that the market price per share of the Company’s common stock, as measured under the terms of the Warrant Transactions, exceeds the strike price of the warrants.

11.    Earnings per Share
The Company adopted ASU 2020-06 on January 1, 2022 using the modified retrospective method of transition. ASU 2020-06 requires the application of the if-converted method for calculating diluted earnings per share, whereas the Company previously calculated diluted earnings per share under the treasury stock method. Basic earnings per share (EPS) is calculated using the weighted average number of common shares outstanding. Diluted EPS is calculated using the weighted average number of common shares outstanding, including the dilutive effect of the Company’s stock option grants, SARs, RSUs, employee stock purchase plan (ESPP) awards, and the 2023 Notes, as determined per the if-converted method for the three months ended March 31, 2022 in connection with the adoption of ASU 2020-06 and the treasury stock method for the three months ended March 31, 2021.
Effect of Convertible Notes and Related Convertible Note Hedges and Warrants
In connection with the issuance of the 2023 Notes, the Company entered into Convertible Note Hedge and Warrant Transactions as described further in Note 9, Convertible Senior Notes Due 2023. The expected collective impact of the Convertible Note Hedge and Warrant Transactions is to reduce the potential dilution that would occur if the price of the Company's common stock was between the conversion price of $59.33 per share and the strike price of the warrants of $80.91 per share.
Diluted EPS related to the 2023 Notes in the current year is calculated using the if-converted method. The number of dilutive shares is based on the initial conversion rate associated with the 2023 Notes. The Convertible Note Hedge and Warrant Transactions are excluded in the calculation of diluted EPS because inclusion would be anti-dilutive. Specifically, the denominator of the diluted EPS calculation excludes the additional shares related to the warrants because the average price of the Company's common stock was less than the strike price of the warrants of $80.91 per share. Prior to actual conversion, the Convertible Note Hedge Transactions are not considered in calculating diluted earnings per share, as their impact would be anti-dilutive.

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

As mentioned in Note 1, as a result of the adoption of ASU 06-2020 on January 1, 2022 the Company calculated diluted earnings per share using the if-converted method. The 6.8 million in dilutive shares associated with the conversion of the 2023 Notes are included in diluted weighted average shares of common stock outstanding for the purposes of calculating diluted earnings per share for the three months ended March 31, 2022. For the three months ended March 31, 2021, the Company calculated diluted earnings per share using the treasury stock method wherein the shares associated with the conversion of the 2023 Notes were excluded as the Company assumed the 2023 Notes would be settled entirely or partly in cash.

Income tax benefit was $10.9 million for the three months ended March 31, 2022 and income tax expense was $5.2 million for the three months ended March 31, 2021. The change for the three months ended March 31, 2022 was primarily from tax benefits associated with the Adamas legal entities reorganization in the first quarter of 2022. The reorganization resulted in favorable impact on certain state apportionment factors. The change in the effective income tax rate for the three months ended March 31, 2022 as compared to the same period in the prior year was mainly due to changes in the effective state tax rates as a result of the Adamas legal entities reorganization.
13.    Leases
Operating Leases
The Company has operating leases for its headquarters lease, certain other office space, and its fleet vehicles. With respect to the fleet vehicle leases, given the volume of individual leases involved in the overall arrangement, the Company applies a portfolio approach to effectively account for the operating lease assets and liabilities. The Company also elected to combine the lease and non-lease components for the fleet vehicle and headquarters leases.
The Company's headquarters lease commenced on February 1, 2019 (the Commencement Date) and will continue until April 30, 2034, unless earlier terminated in accordance with the terms of the lease. The lease includes options to extend the lease for up to 10 years.

Table of Contents

As part of the Adamas Acquisition, the Company acquired a lease for office space. Adamas' operating lease for the office space term will continue until April 30, 2025. The lease contains an option to extend the term for one additional five-year period.
During a measurement period, changes in fair value due to measurement period adjustments are recorded against goodwill. The Company recorded in the first quarter of 2022 a measurement period adjustment associated with the valuation of the acquired Adamas lease which decreased the fair value estimate of the operating lease right of use asset by $1.6 million. Refer to Note 3, Acquisition.
Contract Manufacturing Lease
The Company has a contract manufacturing agreement with Merz Pharma GmbH & Co. KGaA (Merz), for the manufacture and supply of rimabotulinumtoxinB finished products (Merz Agreement). The Merz Agreement will expire in July 2027 unless the Company and Merz mutually agree to extend the terms. The Merz Agreement may not be terminated for convenience.
Under the terms of the agreement, the Company is required to purchase a minimum quantity of MYOBLOC finished products on an annual basis. This minimum purchase requirement represents the in-substance fixed contract consideration associated with the dedicated manufacturing facility which the Company accounts for as an embedded lease.
The Company made an accounting policy election, by class of underlying asset, to not combine lease and non-lease components for the manufacturing facility. A portion of the in-substance fixed contract consideration was allocated to the lease component based on the stand-alone selling price. Accordingly, the Company classifies and accounts for the embedded lease as an operating lease.
Operating lease assets and lease liabilities as reported on the condensed consolidated balance sheets are as follows (dollars in thousands):

As discussed in Note 2, Summary of Significant Accounting Policies, the Company adopted ASU 2020-06 on January 1, 2022. As a result, interest expense for the three months ended March 31, 2022 significantly decreased compared to the three months ended March 31, 2021 due to the Company no longer recording interest expense on the previously recorded discount for the embedded conversion feature on the 2023 Notes. For the three months ended March 31, 2022, interest expense includes noncash interest expense related to amortization of deferred financing costs of $0.5 million. For the three months ended March 31, 2021, interest expense includes noncash interest expense related to amortization of deferred financing costs and amortization of the debt discount on the 2023 Notes of $4.3 million.
16.    Commitments and Contingencies
Product Licenses
The Company has obtained exclusive licenses from third parties for proprietary rights to support the product candidates in the Company's CNS portfolio. Under these license agreements, the Company may be required to pay certain amounts upon the achievement of defined milestones. If these products are ultimately commercialized, the Company is also obligated to pay royalties to third parties, computed as a percentage of net product sales, for each respective product under a license agreement.
Through the USWM Acquisition, the Company acquired licensing agreements with other pharmaceutical companies for APOKYN, XADAGO, and MYOBLOC. The Company is obligated to pay royalties to third parties, computed as a percentage of net product sales, for each of the products under the respective license agreements. The royalty expense incurred for these acquired products is recognized as Cost of goods sold in the condensed consolidated statements of earnings.

Royalty Agreement
In the third quarter of 2014, the Company received $30 million pursuant to a Royalty Interest Acquisition Agreement related to the purchase by HC Royalty of certain of the Company's rights under the Company's agreement with United Therapeutics related to the commercialization of Orenitram (treprostinil) Extended-Release Tablets. Full ownership of the royalty rights will revert to the Company if and when a certain cumulative payment threshold is reached (see Note 2, Note 4, and Note 14).
USWM Enterprise Commitments Assumed
As part of the USWM Acquisition, the Company assumed the remaining commitments of USWM Enterprises and its subsidiaries, which are discussed below.
The Company assumed the annual minimum purchase requirement of MYOBLOC, amounting to an estimated €3.9 million annually, under the contract manufacturing agreement with Merz for manufacture and supply. Refer to Note 13, Leases for further discussion related to the Merz Agreement in connection with the MYOBLOC annual minimum purchase requirement.
In addition, USWM Enterprises had an existing license and distribution agreement for XADAGO. This included an annual minimum promotional spend to support the marketing of XADAGO for the first five years of the agreement and will end in 2022. As of March 31, 2022, there is no remaining contractual commitment.
In March 2019, MDD US Operations, LLC (formerly US WorldMeds, LLC) and its subsidiary, Solstice Neurosciences, LLC (US) (collectively, the MDD Subsidiaries) entered into a Corporate Integrity Agreement (CIA) with the Office of Inspector General of the U.S. Department of Health and Human Services. Under the CIA, the MDD Subsidiaries agreed to and paid $17.5 million to resolve U.S. Department of Justice allegations that it violated the False Claims Act and committed to the establishment and ongoing maintenance of an effective compliance program. The fine was paid by the MDD Subsidiaries prior to closing of the USWM Acquisition. As part of the USWM Acquisition, the Company assumed the obligations of the CIA and could become liable for payment of certain stipulated monetary penalties in the event of any CIA violations. In addition, the Company will continue to incur significant costs through March 2024 to maintain a broad array of processes, policies and procedures necessary to comply with the CIA.
Data Breach-related Contingency
On November 24, 2021, the Company announced that we were the target of a ransomware attack. The attack had no significant impact on our business and did not cause any long-term disruption to our operations. Based on its internal investigation, the Company believes the criminal ransomware groups ("criminal groups") copied certain data from our systems, encrypted certain data on the Company's systems, and then deployed malware designed to impede access to our systems. Thereafter the criminal groups contacted the Company and threatened to publish certain data copied from the Company's systems. Upon detection of the ransomware attack, the Company notified government authorities, engaged third-party cybersecurity experts through our outside counsel, and commenced its recovery process. The Company maintains redundant off-site data backups, which were verified to have not been compromised by the ransomware attack and were utilized to restore the data encrypted by the criminal groups. In the fourth quarter of 2021, the Company had successfully recovered the impacted files and took additional steps designed to further protect its networks and files.
Furthermore, while the Company has not been the subject of any legal proceedings involving the attack, the likelihood that the Company could be the subject of claims from persons alleging they suffered damages from the incident, or actions by governmental authorities is possible, but the amount of such fines, penalties or costs, if any, cannot be estimated at this time. The Company continues to monitor the situation.

Claims and Litigation
From time to time, the Company may be involved in various claims, litigation and legal proceedings. These matters may involve patent litigation, product liability and other product-related litigation, commercial and other matters, and government investigations, among others. On a quarterly basis, the Company reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim, asserted or unasserted, or legal proceeding is considered probable and the amount can be reasonably estimated, the Company will accrue a liability for the estimated loss. Because of uncertainties related to claims, legal proceedings and litigation, accruals will be based on the Company's best estimates based on available information. The Company does not believe that any of these matters will have a material adverse effect on our financial position. The Company may reassess the potential liability related to these matters and may revise these estimates. The process of resolving matters through litigation or other means is inherently uncertain and it is possible that an unfavorable resolution of these matters will adversely affect the Company, its results of operations, financial condition and cash flows.
NAMENDA XR/Namzaric Qui Tam Litigation
On April 1, 2019, Adamas was served with a complaint filed in the United States District Court for the Northern District of California (the District Court) (Case No. 3:18-cv-03018-JCS) against it and several Allergan entities alleging violations of federal and state false claims acts (FCA) in connection with the commercialization of NAMENDA XR and Namzaric by Allergan. The lawsuit is a qui tam complaint brought by an individual, asserting rights of the federal government and various state governments. The lawsuit was originally filed in May 2018 under seal, and Adamas became aware of the lawsuit when it was served. The complaint alleges that patents held by Allergan and Adamas covering NAMENDA XR and Namzaric were procured through fraud on the United States Patent and Trademark Office and that these patents were asserted against potential generic manufacturers of NAMENDA XR and Namzaric to prevent the generic manufacturers from entering the market, thereby wrongfully excluding generic competition resulting in artificially high price being charged to government payors. Adamas' patents in question were licensed exclusively to Forest Laboratories Holdings Limited. The complaint includes a claim for damages of "potentially more than $2.5 billion dollars," treble damages and statutory penalties. To date the federal and state governments have declined to intervene in this action. This case is currently stayed pending Adamas's and Allergan's interlocutory appeal of the District Court's December 11, 2020 order denying Adamas's and Allergan's motion to dismiss the complaint. The appeal is pending in the United States Court of Appeals for the Ninth Circuit (Case No. 21-80005). Argument was held on January 10, 2022 and no decision has been reached as of the date of this filing. The Company intends to defend itself vigorously. However, the Company can offer no assurances that it will be successful in a litigation.
17.    Subsequent Events
On April 29, 2022, the Company announced that the FDA approved an expanded indication for Qelbree (viloxazine extended-release capsules) for the treatment of attention deficit hyperactivity disorder (ADHD) in adult patients aged 18 and older. The FDA has now approved Qelbree for the treatment of ADHD in children (starting at age 6), adolescents and adults.

Overview
We are a biopharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases. Our diverse neuroscience portfolio includes approved treatments for epilepsy, migraine, attention-deficit hyperactivity disorder (ADHD), hypomobility in Parkinson’s Disease (PD), cervical dystonia, chronic sialorrhea, dyskinesia in PD patients receiving levodopa-based therapy, and drug-induced extrapyramidal reactions in adult patients. The Company is developing a broad range of novel CNS product candidates including new potential treatments for hypomobility in PD, epilepsy, depression, and other CNS disorders.
We have a portfolio of commercial products and product candidates.
Commercial Products
Trokendi XR® (topiramate) is the first once-daily extended-release topiramate product indicated for the treatment of epilepsy in patients 6 years of age and older in the United States (U.S.) market. It is also indicated for the prophylaxis of migraine headache in adults and adolescents 12 years and older.
Oxtellar XR® (oxcarbazepine) is indicated as therapy for the treatment of partial onset seizures in patients 6 years of age and older. It is also the first once-daily extended-release oxcarbazepine product indicated for the treatment of epilepsy in the U.S.
Qelbree® (viloxazine extended-release capsules) is a novel non-stimulant product indicated for the treatment of ADHD in adults and pediatric patients 6 years and older. On April 2, 2021, the U.S. Food and Drug Administration (FDA) approved Qelbree for the treatment of ADHD in pediatric patients 6 to 17 years of age. In May 2021, the Company launched Qelbree for pediatric patients in the U.S. On April 29, 2022, the FDA approved Qelbree for treatment of ADHD in adult patients. The Company is expecting to launch Qelbree for adult patients by the end of May 2022.

(1) PDUFA target action date in October 2022.
SPN-830 (apomorphine infusion device)
SPN-830 is a late-stage drug/device combination product candidate for the treatment of continuous treatment of motor fluctuations ("off" episodes) in PD patients patients that are not adequately controlled with oral levodopa and one or more adjunct PD medications. If approved, it would be the only continuous infusion of apomorphine available in the U.S. and an important step for PD patients that would have otherwise been candidates for potentially invasive surgical procedures, such as deep brain stimulation. Continuous infusion may also limit some of the side effects of a subcutaneous injection of apomorphine.
In December 2021, we resubmitted the NDA to the FDA. In February 2022, we received a notice from the FDA that the resubmission of the NDA for SPN-830 is considered as a Standard Review, thereby was assigned a timeline for review of 10 months by the FDA. The PDUFA target action date is October 7, 2022. The Company is preparing for the commercial launch of SPN-830 in the first quarter of 2023 assuming timely approval by the FDA.
SPN-820 (NV-5138)
SPN-820 is a first-in-class, orally active small molecule that directly activates brain mTORC1 (mechanistic target of rapamycin complex 1), a gatekeeper of cellular metabolism and renewal. SPN-820 binds to and modulates sestrin, which senses amino acid availability in the brain, a potent natural activator of mTORC1.
SPN-817 (huperzine A)
SPN-817 represents a novel mechanism of action (MOA) for an anticonvulsant. SPN-817 is a novel synthetic form of
huperzine A, whose MOA includes potent acetylcholinesterase inhibition, with pharmacological activities in CNS conditions such as epilepsy. The development will initially focus on the drug's anticonvulsant activity, which has been shown in preclinical models to be effective for the treatment of partial seizures and Dravet Syndrome. SPN-817 is in clinical development and has received Orphan Drug designation for both Dravet Syndrome and Lennox-Gastaut Syndrome from the FDA.
Adamas Reorganization
In the first quarter of 2022 and subsequent to the Adamas Acquisition, the Company completed a reorganization of the Adamas legal entities in an effort to obtain operational, legal and other benefits that also resulted in certain state tax efficiencies. The legal entities reorganization had no effect on the condensed consolidated financial statements other than certain state tax efficiencies. (See Note 12, Income Taxes.)
COVID-19 Impact
While the impact of the ongoing COVID-19 pandemic did not have a material adverse effect on our financial position or results of operations for the three months ended March 31, 2022, we continue to closely monitor the events and circumstances surrounding the COVID-19 pandemic and its impact on all aspects of our business operations. Since the situation surrounding the COVID-19 pandemic remains fluid and the duration uncertain, the long-term nature and extent of the impacts of the pandemic on

Results of Operations
Comparison of the Three Months Ended March 31, 2022 and 2021
Revenues
Revenues consist primarily of net product sales of our commercial products in the U.S., supplemented by royalty revenues from our collaborative licensing arrangements. The following table provides information regarding our revenues during the three months ended March 31, 2022 (dollars in thousands):

___________________________________________
(1) Includes net product sales of MYOBLOC, XADAGO and OSMOLEX ER.
The $19.1 million and 15% increase in net product sales for the three months ended March 31, 2022, as compared to the same period in 2021, was primarily due to the inclusion of $22.6 million in net product sales of GOCOVRI, subsequent to the completion of the Adamas Acquisition in November 2021, as well as $8.3 million net product sales from Qelbree, which was launched in May 2021. Partially offsetting this increase was a $9.0 million decrease in net product sales of Trokendi XR and a $3.3 million decrease in net product sales of APOKYN.
Trokendi XR net product sales decreased by 13% to $62.8 million for the three months ended March 31, 2022 as compared to the same period in 2021. This decrease was attributable primarily to the decline in unit demand offset by the price increase taken in January 2022. APOKYN net product sales decreased by 15% to $18.4 million for the three months ended March 31, 2022 as compared to the same period in 2021. This decrease was primarily attributable to the decline in unit demand due to competitive headwinds.
Sales Deductions and Related Accruals
We record accrued product returns and accrued product rebates as current liabilities in Accrued product returns and rebates, on our condensed consolidated balance sheets. We record sales discounts as a reduction against Accounts receivable on the condensed consolidated balance sheets. Both amounts are generally affected by changes in gross product sales, changes in the provision for net product sales deductions, and the timing of payments/credits.

Balance at March 31, 2022$104,948 $35,233 $11,443 $151,624 
The increase in accrued product rebates liabilities was primarily attributable to greater utilization of our patient co-payment programs, as well as higher per patient payments under both government and commercial managed care programs. The increase in accrued product returns liabilities was primarily due to the timing of related return activity. The decrease to accounts receivable for sales discounts is primarily due to the timing of payments.
Royalty Revenues
Royalty revenues include a royalty from net product sales of Mydayis, a product of Takeda Pharmaceuticals Company Ltd., Namzaric royalties, and noncash royalty revenue pursuant to our agreement with Healthcare Royalty Partners III, L.P. (HC Royalty). HC Royalty receives royalty payments from United Therapeutics Corporation (United Therapeutics) based on net product sales of United Therapeutics’ product Orenitram.
Royalty revenues were $5.0 million and $2.6 million for the three months ended March 31, 2022 and 2021, respectively. The increase was primarily due to the Namzaric royalties for the three months ended March 31, 2022. Namzaric royalty rights were acquired in connection with the Adamas Acquisition.
Cost of Goods Sold
Cost of goods sold was $17.9 million and $15.0 million for the three months ended March 31, 2022 and 2021, respectively. The $2.9 million increase was primarily attributable to inclusion of cost of goods sold of the acquired commercial products from the Adamas Acquisition and of Qelbree, which launched in May 2021.
Research and Development Expenses
R&D expenses were $20.8 million and $34.3 million for the three months ended March 31, 2022 and 2021, respectively. The $13.5 million decrease was primarily due to the write-down of the $15.0 million investment in Navitor LLC which was attributable to a single in-process research and development (IPR&D) asset and recorded in R&D expense in the first quarter of 2021.
Selling, General and Administrative Expenses
The following table provides information regarding our selling, general and administrative (SG&A) expenses during the periods indicated (dollars in thousands):

 Total $90,459 $61,457 $29,002 47%
34

Table of Contents

Selling, general and administrative expenses increased by 47% to $90.5 million for the three months ended March 31, 2022. The $29.0 million increase was primarily attributable to increased marketing expenses and professional consulting spend related to the commercial products, including the acquired commercial products from the Adamas Acquisition, and increased Qelbree costs to support current period net product sales as well launch preparation activities for the launch of Qelbree for adults. Qelbree for pediatric patients was launched in May 2021. General and administrative expenses increased due to higher professional and consulting costs to support IT and finance operations for ransomware, financial reporting and Adamas integration in 2022.
Amortization of Intangible Assets
Amortization of intangible assets was $20.6 million and $6.0 million for the three months ended March 31, 2022 and 2021, respectively. The $14.6 million increase was due to amortization of the definite-lived intangible assets acquired in the Adamas Acquisition.
Contingent Consideration Expense
Contingent consideration expense of $0.7 million and $1.0 million for the three months ended March 31, 2022 and 2021, was primarily due to changes in the estimated fair value of contingent consideration due to the passage of time, an increase in the probability of milestone achievement of certain regulatory and developmental USWM milestones, partially offset by the decrease in the estimated fair value of sales-based Adamas milestones due to volatility in the market data movements.
Other Income (Expense)
Other income (expense) was income of $12.8 million and an expense of $2.3 million for the three months ended March 31, 2022 and 2021, respectively. The $15.0 million increase in other income was primarily due to $12.9 million in connection with the gain associated with the Navitor investment and a decrease in interest expense of $4.2 million primarily related to the Company's adoption of ASU 2020-06 on January 1, 2022. As a result of the adoption, the Company no longer records interest expense on the previously recorded discount for the embedded conversion feature on the 2023 Notes.
Income Tax (Benefit) Expense
Income tax (benefit) expense was a benefit of $10.9 million and an expense of $5.2 million for the three months ended March 31, 2022 and 2021, respectively. The decrease was mainly due to the Adamas reorganization in the first quarter of 2022. The effective income tax rate was (74.0)% and 47.9% for the three months ended March 31, 2022 and 2021, respectively. The effective income tax rate decrease was due to changes in the effective state tax rates as a result of the Adamas reorganization in the first quarter of 2022.
Liquidity and Capital Resources
We have financed our operations primarily with cash generated from product sales, supplemented by revenues from royalty and licensing arrangements, as well as proceeds from the sale of equity and debt securities. Continued cash generation is highly dependent on the success of our commercial products, as well as the success of our product candidates if approved by the FDA. While we expect continued profitability in future years, we anticipate there may be significant variability from year to year in the level of our profits particularly due to the commercial launch of Qelbree in May 2021; future commercial launches of Qelbree for the treatment of ADHD in adults (approved by the FDA in April 2022) and SPN-830 (apomorphine infusion device), if approved by the FDA; continued market and payor pressures for our commercial products; and the likely unfavorable impact of the upcoming loss of patent exclusivity for Trokendi XR in January 2023, or sooner under certain conditions.
The Company believes its balances of cash, cash equivalents and unrestricted marketable securities, which totaled $437.5 million as of March 31, 2022, along with cash generated from ongoing operations and continued access to debt markets, will be sufficient to satisfy its cash requirements over the next 12 months and beyond.
We may, from time to time, consider raising additional capital through: new collaborative arrangements; strategic alliances; additional equity and/or debt financings; or financing from other sources, especially in conjunction with opportunistic business development initiatives. We will continue to actively manage our capital structure and to consider all financing opportunities that could strengthen our long-term financial profile. Any such capital raises may or may not be similar to transactions in which we have engaged in the past. There can be no assurance that any such financing opportunities will be available on acceptable terms, if at all.

Total cash and cash equivalents, marketable securities and long-term marketable securities decreased by $21.3 million in the first three months of 2022 primarily due to the $25 million contingent consideration payment related to FDA acceptance of the SPN-830 NDA for review.
As of March 31, 2022 and December 31, 2021, the outstanding principal on our 0.625% Convertible Senior Notes Due 2023 (2023 Notes) was $402.5 million. No 2023 Notes have been converted as of March 31, 2022. There were no changes to the separate convertible note hedge transactions (collectively, the Convertible Note Hedge Transactions) and separate warrant transactions (the Warrant Transactions). Refer to Part I, Item 1, Unaudited Condensed Financial Statements, Note 9, Convertible Senior Notes Due 2023, in the Notes to the Condensed Consolidated Financial Statements, for further discussion of the 2023 Notes and our other indebtedness.
Summary of Cash Flows

Three Months ended March 31,Change
20222021Amount
 Net cash provided by (used in):
 Operating activities $4,302 $36,200 $(31,898)

 Financing activities (22,034)2,247 (24,281)
 Net change in cash and cash equivalents $(87,719)$(32,998)$(54,721)
Operating Activities
Net cash provided by operating activities was $4.3 million and $36.2 million for the three months ended March 31, 2022, and 2021, respectively. The decrease in cash flows provided by operating activities is primarily due to changes in working capital which reflects the timing impacts of: cash collections on receivables and settlement of payables.
Investing Activities
Net cash used in investing activities was $70.0 million and $71.4 million for the three months ended March 31, 2022 and 2021, respectively. Net cash used in investing activities primarily reflect cash flows from purchase, sale and maturities of marketable securities.
Financing Activities
Net cash used by financing activities were $22.0 million for the three months ended March 31, 2022 compared to $2.2 million provided during the same period in 2021, primarily due to the payment of a contingent consideration milestone associated with the USWM Acquisition and lower proceeds from option exercises.
Material Cash Requirements
Refer to “Part II, Item 7 — Management’s Discussion and Analysis of Liquidity and Capital Resources”, of our Annual Report on Form 10-K for the year ended December 31, 2021, and Note 16, Commitments and Contingencies, in the Notes to the Condensed Consolidated Financial Statements in Part I, Item 1, Unaudited Condensed Financial Statements, of this Quarterly Report on Form 10-Q for the discussion of our contractual obligations.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk
The primary objective of our investment activities is to preserve our capital to fund operations and to facilitate business development activities. We also seek to maximize income from our investments without assuming significant interest rate risk, liquidity risk, or risk of default by investing in investment grade securities with maturities of four years or less. Our exposure to market risk is confined to investments in cash and cash equivalents, marketable securities, and long-term marketable securities. As of March 31, 2022, we had unrestricted cash, cash equivalents, marketable securities, and long-term marketable securities of
$437.5 million.
In connection with the 2023 Notes, we have separately entered into Convertible Note Hedge Transactions and Warrant Transactions to reduce the potential dilution of the Company’s common stock upon conversion of the 2023 Notes, and to partially offset the cost to purchase the Convertible Note Hedge Transactions, respectively.
Our cash and cash equivalents consist primarily of cash held at banks and investments in highly liquid financial instruments with an original maturity of three months or less. Our marketable securities, which are reported at fair value, consist of money market funds; corporate and municipal debt securities; and other fixed income securities. We place all investments with governmental, industrial, or financial institutions whose debt is rated as investment grade. These securities have maturities of one to four years. Because of the relatively short period that we hold our investments and because we generally hold these securities to maturity, we do not believe that an increase in interest rates would have any significant impact on the realizable value of our investments. We do not have any currency or other derivative financial instruments other than outstanding warrants to purchase common stock and the convertible note hedges.
We may contract with clinical research organizations (CROs) and investigational sites globally. Currently, we have three ongoing trials, two of which are being conducted globally, and one which is being conducted outside the U.S. We do not hedge our foreign currency exchange rate risk. Transactions denominated in currencies other than the U.S. dollar are recorded based on exchange rates at the time such transactions arise. As of March 31, 2022 and December 31, 2021, substantially all of our liabilities were denominated in the U.S. dollar.
Inflation generally affects us by increasing our cost of labor and the cost of services provided by our vendors. We do not believe that inflation has had a material effect on our business, financial condition or results of operations. Nonetheless, if our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm our business, financial condition and results of operations.
Item 4.    Controls and Procedures
Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures required by Rule 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in the reports we file or submit under the Exchange Act has been appropriately recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission's rules and forms and that such information is accumulated and communicated to our management, including our CEO and CFO, to allow timely decisions regarding required disclosure. We conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2022, the end of the period covered by this report. Based on that evaluation, under the supervision and with the participation of our management, including our CEO and CFO, we concluded that our disclosure controls and procedures were not effective as of March 31, 2022 due to the continued material weaknesses in our internal control over financial reporting as described below and in our Annual Report on Form 10-K as of December 31, 2021, which was filed on April 13, 2022.
In light of the identified material weaknesses, we performed additional analyses and other procedures to ensure that the condensed consolidated financial statements included in this quarterly report on Form 10-Q present fairly, in all material respects, the Company's financial position, results of operations and cash flows for the periods disclosed in conformity with U.S. generally accepted accounting principles (U.S. GAAP).

Table of Contents

As discussed in Note 3 in the Notes to the Condensed Consolidated Financial Statements in Part I, Item 1, of this report, the Company completed its acquisition of Adamas Pharmaceuticals, Inc. (Adamas), a publicly traded biopharmaceutical company (Adamas Acquisition) on November 24, 2021. We are in the process of integrating Adamas with our controls over financial reporting. As such, the scope of our assessment of the effectiveness of our disclosure control and procedures as of March 31, 2022 did not include the internal control over financial reporting of Adamas, as permitted by the guidance of the Office of the Chief Accountant of the SEC (not to extend more than one year beyond the date of acquisition or for more than one annual reporting period).
Previously Reported Material Weaknesses in Internal Control over Financial Reporting
As previously disclosed in Item 9A, Controls and Procedures, on Form 10-K filed April 13, 2022, as of and for the year ended December 31, 2021, we identified deficiencies resulting in the material weaknesses further described below. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis.
On November 24, 2021, the Company disclosed that it was the target of a ransomware attack. The 2021 ransomware attack resulted in the unauthorized encryption of certain data used by the Company’s legacy enterprise resource planning (“ERP”) system. In addition, the Company also announced on the same date that it had completed the closing of the Adamas acquisition. As a result of these events, the Company’s financial and IT operations changed and the circumstances necessitated further re-consideration of the Company’s control environment, risk assessment, information and communication, control monitoring, and control activities. Specifically, commencing with the fourth quarter of 2021 and continuing into 2022, management was unable to adjust its controls, nor retain sufficient resources to reflect the needs arising from:
(a) the result of the ransomware incident, its effects and significant impact on the following:
i) the Company’s ability to access and reinstate its financial ERP system for an extended period to a new normal state of operation;
ii) the resource needs to rebuild its financial information from backups as a result of the ransomware incident;
iii) additional workload associated with process workflows that were previously automated but are currently manually performed as a result of the ransomware attack.
(b) the Adamas acquisition and the related preliminary purchase price accounting; and
(c) operating the financial reporting environment of Adamas.
These responsibilities were assigned to the finance organization in addition to their historical job responsibilities.
Due to the factors noted above, the Company did not have sufficient resources and as a result, the Company did not adequately perform the following:
(a) assess, redesign and timely evaluate performance of controls over financial reporting risks as a result of existing circumstances;
(b) train, monitor, and supervise newly hired contractors and employees; and
(c) generate real time information across the organization to allow the finance department to perform timely controls.
In the aggregate, these deficiencies create a reasonable possibility that material misstatements in substantially all financial reporting processes and financial statement accounts in our consolidated financial statements will not be prevented or detected on a timely basis and, therefore, we concluded that the deficiencies represent material weaknesses in our internal control over financial reporting.
Remediation Plan
Management is actively remediating the identified material weaknesses, and is committed to remediating the material weaknesses in a timely manner. Our remediation process is ongoing and includes the following steps, but is not limited to, the following:
(a) accelerated implementation of a new ERP system to reduce resource constraints and to automate certain processes that are currently being performed manually as a result of the ransomware attack;
(b) re-evaluation of all controls, including redesigning controls and control procedures, performing risk assessment procedures, as well as adding new controls as necessary;
(c) continue to actively recruit personnel or hire consultants that have requisite knowledge, experience, and expertise over financial reporting and internal control over financial reporting. We will continue to evaluate our current and future staffing needs to add personnel and/or create new roles to address our needs; and
38

Table of Contents

(d) training/re-training, monitoring, and enhancing communication of control objectives to hired employees and contractors on internal control over financial reporting.

While the audit committee of our board of directors and senior management are closely monitoring the remediation efforts, until the remediation efforts discussed in this section, including any additional remediation efforts that our senior management identifies as necessary, are complete, tested and determined effective, we will not be able to conclude that the material weaknesses have been remediated. In addition, we will continue to incur incremental costs associated with this remediation, primarily due to the hiring and training of additional personnel, and the improvements in our IT infrastructure. The material weaknesses will not be considered remediated until the above system, controls and personnel are in place for a period of time, the applicable controls operate for a sufficient period of time and management concludes based on its testing and evaluation that these controls are properly designed and operating effectively.
Changes in Internal Control over Financial Reporting
Our management, including our CEO and CFO, evaluated changes in our internal control over financial reporting that occurred during the quarter ended March 31, 2022.
We began the process to integrate the financial reporting systems and processes of the business acquired through the Adamas Acquisition into ours in 2021. As the phased implementation of the integration continues in 2022, we are experiencing certain changes to our processes and procedures, which, in turn, result in changes to our internal control over financial reporting. While management has extended its oversight and monitoring processes that support our internal control over financial reporting, we continue to integrate the operations of Adamas, which may result in additions and changes in our internal controls over financial reporting.
Except for: 1) the above noted and previously reported material weaknesses and the remediation activities that have already begun, including the implementation of a new ERP system which is currently in process, and 2) the ongoing integration of Adamas, there were no other changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rule 13a-15 that occurred during the quarter ended March 31, 2022 that have materially affected or are reasonably likely to materially affect, our internal control over financial reporting.
PART II — OTHER INFORMATION
Item 1.    Legal Proceedings
From time to time and in the ordinary course of business, Supernus Pharmaceuticals, Inc. ("Company") and any of its subsidiaries may be subject to various claims, charges and litigation. Parent and any of its subsidiaries may be required to file infringement claims against third parties for the infringement of our patents.
Oxtellar XR®
Supernus Pharmaceuticals, Inc. v. Apotex Inc., et al., C.A. No. 20-cv-7870 (FLW)(TJB) (D.N.J.)
The Company received a Paragraph IV Notice Letter from generic drug makers Apotex Inc. and Apotex Corp. (collectively, “Apotex”) dated May 13, 2020 directed to nine of its Oxtellar XR® Orange Book patents. Supernus’s U.S. Patent Nos. 7,722,898; 7,910,131; 8,617,600; 8,821,930; 9,119,791; 9,351,975; 9,370,525; 9,855,278; and 10,220,042 generally cover once-a-day oxcarbazepine formulations and methods of treating seizures using those formulations. The FDA Orange Book lists all nine of the Company’s Oxtellar XR® patents as expiring on April 13, 2027. On June 26, 2020, the Company filed a lawsuit against Apotex alleging infringement of the Company’s nine patents. The Complaint—filed in the U.S. District Court for the District of New Jersey—alleges, inter alia, that Apotex infringed the Company’s Oxtellar XR® patents by submitting to the FDA an Abbreviated New Drug Application (“ANDA”) seeking to market a generic version of Oxtellar XR® prior to the expiration of the Company’s patents. Filing its June 26, 2020 Complaint within 45 days of receiving Apotex’s Paragraph IV certification notice entitles Supernus to an automatic stay preventing the FDA from approving Apotex’s ANDA for 30 months from the date of the Company’s receipt of the Paragraph IV Notice Letter. On September 4, 2020, Apotex answered the Complaint and denied the substantive allegations of the Complaint, asserting affirmative defenses that include non-infringement and invalidity. Apotex also asserted Counterclaims seeking declaratory judgments of non-infringement for the nine Oxtellar XR® Orange Book patents. On October 30, 2020, the Company filed its Reply, denying the substantive allegations of Apotex’s Counterclaims. On January 27, 2022, the Court issued an Order staying all litigation proceedings and administratively terminated the action until the stay is lifted. As of the date of this submission, this case remains administratively terminated.

Supernus Pharmaceuticals, Inc. v. Apotex Inc., et al., C.A. No. 3:22-cv-00322-FLW-TJB (FLW)(TJB) (D.N.J.)
The Company received a Paragraph IV Notice Letter from generic drug makers Apotex Inc. and Apotex Corp. (collectively, “Apotex”) dated December 10, 2021 directed to one of its Oxtellar XR® Orange Book patents. Supernus’s U.S. Patent No. 11,166,960 generally covers once-a-day oxcarbazepine formulations and methods of treating seizures using those formulations. The FDA Orange Book lists U.S. Patent No. 11,166,960 as expiring on April 13, 2027. On January 24, 2022, the Company filed a lawsuit against Apotex alleging infringement of U.S. Patent No. 11,166,960. The Complaint—filed in the U.S. District Court for the District of New Jersey—alleges, inter alia, that Apotex infringed the Company’s Oxtellar XR® patents by submitting to the FDA an Abbreviated New Drug Application (“ANDA”) seeking to market a generic version of Oxtellar XR® prior to the expiration of U.S. Patent No. 11,166,960. On January 27, 2022, in related Civil Action No. 20-cv-7870 (FLW)(TJB) (D.N.J.), the Court issued an Order staying all litigation proceedings and administratively terminated that related action until the stay is lifted.

XADAGO®
On June 10, 2021, Newron Pharmaceuticals S.p.A. (“Newron”), Zambon S.p.A. (“Zambon”) and Supernus Pharmaceuticals, Inc. (the “Company”), through its subsidiary MDD US Operations, LLC (collectively, “Plaintiffs”), initiated litigation against generic drug makers Aurobindo Pharma Limited, Aurobindo Pharma USA Inc., MSN Laboratories Private Limited (“MSN”), Optimus Pharma Pvt Ltd, Prinston Pharmaceutical, Inc., RK Pharma, Inc. and Zenara Pharma Private Limited (collectively, “Defendants”) for infringement of three FDA Orange Book patents covering XADAGO®, the Company’s once-daily product indicated as adjunctive treatment to levodopa/carbidopa in patients with Parkinson’s Disease experiencing “off” episodes. U.S. Patent Nos. 8,076,515, 8,278,485 and 8,283,380 (collectively, the “XADAGO Patents”) cover the pharmaceutical formulation of and methods of treatment with safinamide. The XADAGO Patents expire between June 2027 and March 2031. The Company has a license agreement with Zambon, Newron’s partner, related to the XADAGO Patents, and as a new chemical entity, XADAGO was under the 5-year FDA exclusivity period that expired on March 21, 2022. The Complaint – filed in the U.S. District Court for the District of Delaware – alleges that the Defendants infringed the XADAGO Patents by submitting to the U.S. Food and Drug Administration (FDA) Abbreviated New Drug Applications (ANDAs) seeking to market a generic version of XADAGO prior to the expiration of the patents. Filing the Complaint within 45 days of receiving each of the Defendants’ Paragraph IV notice letters entitles the Plaintiffs to an automatic stay preventing the FDA from approving the Defendants’ ANDAs for 30 months from the date of the Plaintiffs’ receipt of the Paragraph IV Notice Letters.

schedule. A trial has been set for January 8, 2024. On March 22, 2022, defendant Optimus Pharma Pvt Ltd was dismissed from the case without prejudice. Fact discovery is ongoing with the remaining defendants.
Adamas Litigation
In November 2012, Adamas Pharmaceuticals, Inc. (Adamas) granted Forest Laboratories Holdings Limited, an indirect wholly-owned subsidiary of Allergan plc (Forest), an exclusive license to certain of Adamas's intellectual property rights relating to human therapeutics containing memantine in the United States. Under the terms of that license agreement, Forest has the right to enforce such intellectual property rights which are related to its right to market and sell Namzaric and NAMENDA XR for the treatment of moderate to severe dementia related to Alzheimer's disease. Adamas has a right to participate in, but not control, such enforcement actions by Forest.
Since 2018 multiple generic companies have launched generic versions of NAMENDA XR. A number of companies have submitted ANDAs including one or more certifications to the FDA, pursuant to 21 U.S.C. § 355(j)(2)(A)(vii)(iv), requesting approval to manufacture and market generic versions of Namzaric, on which Adamas became entitled to receive royalties from Forest beginning in May 2020.
Adamas and Forest have settled with all such Namzaric ANDA filers, including all first filers on all the available dosage forms of Namzaric. Subject to those agreements, the earliest date on which any of these agreements grant a license to market a Namzaric ANDA filer's generic version of Namzaric is January 1, 2025 (or earlier in certain circumstances). Alternatively, the Namzaric ANDA filers with the earliest date have the option to launch an authorized generic version of Namzaric beginning on January 1, 2026 instead of launching their own generic version of Namzaric on January 1, 2025. Adamas and Forest intend to continue to enforce the patents associated with Namzaric.
On April 1, 2019, Adamas was served with a complaint filed in the United States District Court for the Northern District of California (Case No. 3:18-cv-03018-JCS) against it and several Forest and Allergan entities alleging violations of federal and state false claims acts (FCA) in connection with the commercialization of NAMENDA XR and Namzaric by Allergan. The lawsuit is a qui tam complaint brought by a named individual, Zachary Silbersher, asserting rights of the Federal government and various state governments. The lawsuit was originally filed in May 2018 under seal, and Adamas became aware of the lawsuit when it was served. The complaint alleges that patents held by Allergan and Adamas covering NAMENDA XR and Namzaric were procured through fraud on the United States Patent and Trademark Office and that these patents were asserted against potential generic manufacturers of NAMENDA XR and Namzaric to prevent the generic manufacturers from entering the market, thereby wrongfully excluding generic competition resulting in artificially high prices being charged to government payors. Adamas's patents in question were licensed exclusively to Forest. The complaint includes a claim for damages of “potentially more than $2.5 billion dollars,” treble damages and statutory penalties. To date the federal and state governments have declined to intervene in this action. This case is currently stayed pending Adamas's and Allergan's interlocutory appeal of the District Court's December 11, 2020 order denying Adamas's and Allergan's motions to dismiss the complaint. The appeal is pending in the United States Court of Appeals for the Ninth Circuit (Case No. 21-80005). Argument was held on January 10, 2022 and no decision has been reached as of the date of this filing.
On December 10, 2019, a putative class action lawsuit alleging violations of the federal securities laws was filed by Ali Zaidi against Adamas and certain of Adamas's former directors and officers in federal court in the Northern District of California (Case No. 4:19-cv-08051). This lawsuit alleges violations of the Securities Exchange Act of 1934 by Adamas and certain of Adamas's former directors and officers. On October 8, 2021, the presiding judge dismissed the litigation, and granted Plaintiffs leave to amend their complaint. On November 5, 2021, Plaintiffs filed their second amended class action complaint. On December 10, 2021, Adamas filed a motion to dismiss the Second Amended Complaint. Plaintiffs opposed the motion to dismiss. The motion to dismiss remains pending.
On March 16, 2020, a shareholder derivative lawsuit was filed by Patrick Van Camp in federal court in the Northern District of California (Case No. 4:20-cv-01815) naming Adamas and certain of Adamas's former directors and officers as defendants. This lawsuit alleges certain of Adamas's former directors and officers breached fiduciary duties and violated the Securities Exchange Act of 1934. Adamas is named as a nominal defendant only. On April 6, 2020, another, virtually identical, shareholder derivative lawsuit was filed by James Druzbik in federal court in the Northern District of California (Case No. 4:20-cv-02320) naming Adamas and certain of Adamas's former directors and officers as defendants. This lawsuit contains the same allegations, claims, and defendants as the first derivative action. Adamas is named as a nominal defendant only. In both actions, Plaintiffs seek unspecified monetary damages and other relief. These actions have been consolidated and are stayed pending resolution of the Zaidi class action.
Adamas believes it has strong factual and legal defenses to all actions and intends to defend itself vigorously.
