2.     BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with instructions to Form 10-Q and Article 10 of Regulation S-X. TheAccordingly, these financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the condensed consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) that the Company believes areconsidered necessary for athe fair presentation of the periods presented. The condensed consolidated balance sheet at December 31, 20162019 was derived from the audited consolidated financial statements, but does not include all disclosures required by U.S. GAAP.
These interim financial results are not necessarily indicative of results to be expected for the full fiscal year ending December 31, 2020, or any other future period andperiod. Readers should be read these interim unaudited condensed consolidated financial statements in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2016,2019, included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission, or SEC. The Company’s critical accounting policies are detailed in its Annual Report on Form 10-K for the year ended December 31, 2019. The Company’s critical accounting policies have not changed materially from December 31, 2019.
Use of Estimates
The preparation of the accompanying consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses in the consolidated financial statements and the accompanying notes. On an ongoing basis, management evaluates its estimates, including those related to revenue recognition and variable consideration, lease assets and liabilities, clinical trial accruals, fair value of assets and liabilities including short-term and long-term classification, embedded derivatives, income taxes, inventory, and stock-based compensation. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that management believes to be reasonable under the circumstances. Actual results may differ from those estimates.
LiquidityRisks and Financial ConditionUncertainties
To date, a significant portionThe outbreak of the Company’s resourcesnovel Coronavirus (“COVID-19”), which is understood to have been dedicatedbegun in December 2019, continues to grow both within the U.S. and globally. The World Health Organization has declared the outbreak of COVID-19 to be a pandemic, and the U.S. federal government has declared it a national emergency. The Company is subject to risks and uncertainties as a result of the outbreak of COVID-19. Despite disruptions to the researchCompany’s business operations, the COVID-19 pandemic did not significantly impact GOCOVRI prescription refill rates for the three months ended March 31, 2020, and developmentthus far management has observed no disruptions to its inventory on hand or planned manufacturing schedule.

healthcare providers have temporarily closed their offices or are restricting patient visits; patients are postponing visits to healthcare provider facilities; and the sales force has moved to conducting activities virtually with healthcare providers. While management believes this decline in new prescriptions to be temporary, the duration and severity is dependent on future developments, including new information that may emerge concerning the actions taken to contain or prevent further spread, all of which are highly uncertain and cannot be predicted with confidence.
As of the date of issuance of these condensed consolidated financial statements, due to the numerous uncertainties surrounding the COVID-19 pandemic, the Company is unable to predict the extent of the impact that the COVID-19 pandemic may have on the Company’s future business, financial results, liquidity and cash flows.

As of March 31, 2020, the Company had $115.3 million of cash, cash equivalents, and investments, of $130.7 million as of September 30, 2017which management believes will be adequatesufficient to satisfyfund its projected operating requirements, including commercialization of GOCOVRI for the Company’s capital needs throughtreatment of dyskinesia in patients with Parkinson’s disease and operations related to the continued development of ADS-5102 for other indications including MSW, for at least the next twelve12 months from the issuance of this Quarterly Reportquarterly report on Form 10-Q. However, the process of developing and commercializing products requires significant research and development, preclinical testing and clinical trials, manufacturing arrangements, as well as regulatory approvals. These activities, together with the Company’s selling, general and administrative expenses, are expected to result in significant operating losses until the commercialization of the Company’s products or license agreements generate sufficient revenue to offset expenses. While the Company had net income during 2014, 2013, and 2012, it has not generated any commercial revenue from sales of its products. Under its license agreement with Allergan, the Company received the final milestone payment in 2014, and is not entitled to receive any royalties for net sales of Namzaric® until mid-2020 and Namenda XR® until mid-2018. To achieve sustained profitability, the Company, alone or with others, must successfully develop its product candidates, obtain required regulatory approvals, and successfully manufacture and market its products. 
Inventory
Inventory is stated at the lower of cost or estimated net realizable value with cost determined under the first-in first-out method. Inventory consists of raw materials, work-in-process, and GOCOVRI finished goods. Raw materials and work-in-processpossible that may be utilized for both commercial and clinical programs are included in inventory and charged to research and development expense when the product enters the research and development process and can no longer be used for commercial purposes. Costs include active pharmaceutical ingredient (API), third-party contract manufacturing, third-party packaging services, freight, labor costs for personnel involved in the manufacturing process,

and indirect overhead costs. If the Company identifies excess, obsolete or unsalable product, the Company will write down its inventorynot achieve the progress it expects, because revenues from GOCOVRI may be less than anticipated, especially in light of the current COVID-19 pandemic, and the actual costs and timing of drug development, particularly clinical studies, and regulatory approvals are difficult to its net realizable value inpredict, subject to substantial risks and delays, and often vary depending on the period it is identified.
The Company begins capitalizing costs as inventory when the product candidate receives regulatory approval. Prior to regulatory approval, inventory costs related to product candidates are recorded as researchparticular indication and development expense. The Company received FDA approval for GOCOVRI onstrategy.

Revenue Recognition
The Company recognizes revenue when all four of the following criteria have been met: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services have been rendered, (iii) the fee is fixed or determinable, and (iv) collectability is reasonably assured. Revenue under license arrangements is recognized based on the performance requirements of the contract. Determinations of whether persuasive evidence of an arrangement exists and whether delivery has occurred or services have been rendered are based on management’s judgments regarding the fixed nature of the fees charged for deliverables and the collectability of those fees. Should changes in conditions cause management to determine that these criteria are not met for any new or modified transactions, revenue recognized could be adversely affected.
The Company generates revenue from collaboration and license agreements for the development and commercialization of products. Collaboration and license agreements may include non-refundable upfront license fees, partial or complete reimbursement of research and development costs, contingent consideration payments based on the achievement of defined objectives, and royalties on sales of commercialized products. The Company’s performance obligations under the collaboration and license agreements may include the license or transfer of intellectual property rights, obligations to provide research and development services and related materials, and obligations to participate on certain development and/or commercialization committees with the partners.
For revenue agreements with multiple-element arrangements, the Company allocates revenue to each non-contingent element based on the relative-selling-price of each element in an arrangement. When applying the relative-selling-price method, the Company determines the selling price for each deliverable using the following estimation hierarchy: (i) vendor-specific objective evidence of fair value of the deliverable, if it exists, (ii) third-party evidence of selling price, if vendor-specific objective evidence is not available, or (iii) the vendor’s best estimate of selling price, if neither vendor-specific nor third-party evidence is available. Revenue allocated is then recognized when the four basic revenue recognition criteria, mentioned above, are met for each element.
The Company recognizes payments that are contingent upon achievement of a substantive milestone in their entirety in the period in which the milestone is achieved. Milestones are defined as events that can only be achieved based on the Company’s performance and there is substantive uncertainty about whether the event will be achieved at the inception of the arrangement. Events that are contingent only on the passage of time or only on counterparty performance are not considered milestones subject to this guidance. Further, the amounts received must relate solely to prior performance, be reasonable relative to all of the deliverables and payment terms within the agreement and commensurate with the Company’s performance to achieve the milestone after commencement of the agreement.
Amounts related to research and development funding and full-time equivalent employees assigned to the license agreement are recognized as the related services or activities are performed, in accordance with the contract terms. 
Accounts Receivable
The Company’s accounts receivable balance consists of amounts due from Allergan, in accordance with the contract terms of the license agreement, for research and development funding and full-time equivalent employees assigned to the Allergan license agreement, as well as for reimbursement of external costs, recorded as contra-expense, associated with supporting prosecution and litigation of intellectual property rights. 
Clinical Trial Accruals
The Company’s clinical trial accruals are based on estimates of patient enrollment and related costs at clinical investigator sites as well as estimates for the services received and efforts expended pursuant to contracts with multiple

research institutions and contract research organizations (“CROs”) that conduct and manage clinical trials on the Company’s behalf. 
The Company estimates clinical trial expenses based on the services performed pursuant to contracts with research institutions and CROs that conduct and manage clinical trials on its behalf. In accruing service fees, the Company obtains the reported level of patient enrollment at each site and estimates the time period over which services are to be performed and activity expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, the Company will adjust the accrual accordingly. Payments made to third parties under these arrangements in advance of the receipt of the related services are recorded as prepaid expenses until the services are rendered. 
Research and Development
Research and development (“R&D”) expenses include salaries and related compensation, contractor and consultant fees, external clinical trial expenses performed by CROs, licensing fees, acquired intellectual property with no alternative future use, and facility and administrative expense allocations. In addition, the Company funds R&D at research institutions under agreements that are generally cancelable at its option. Research costs typically consist of applied research and preclinical and toxicology work. Pharmaceutical manufacturing development costs consist of pre-approval inventory purchases, product formulation, chemical analysis, and the transfer and scale-up of manufacturing at facilities operated by the Company’s contract manufacturers. Clinical development costs include the costs of Phase 1, Phase 2, and Phase 3 clinical trials. These costs are a significant component of the Company’s research and development expenses. 
The Company accrues costs for clinical trial activities performed by CROs and other third parties based upon the estimated amount of work completed on each study as provided by the CRO. These estimates are reviewed for reasonableness by the Company’s internal clinical personnel, and the Company aims to match the accrual to actual services performed by the organizations as determined by patient enrollment levels and related activities. The Company monitors patient enrollment levels and related activities using available information; however, if the Company underestimates activity levels associated with various studies at a given point in time, the Company could be required to record significant additional R&D expenses in future periods when the actual activity level becomes known. The Company charges all such costs to R&D expenses. Non-refundable advance payments are capitalized and expensed as the related goods are delivered or services are performed.
Long-Term Debt
Long-term debt consists of the Company’s loan agreement with HealthCare Royalty Partners (“HCRP”). The Company accounted for the loan agreement as a debt financing arrangement. Interest expense is accrued using the effective interest rate method over the estimated period the debt will be repaid. Debt issuance costs have been recorded as a debt discount in the Company’s consolidated balance sheets and are being amortized and recorded as interest expense throughout the life of the loan using the effective interest rate method. The Company must make certain assumptions and estimates, including future royalties and net product sales, in determining the expected repayment term and amortization period of the debt discount, as well as the classification between current and long-term portions. The Company periodically assesses these assumptions and estimates, and adjusts the liabilities accordingly.
Embedded Derivatives Related to Debt Instruments
Embedded derivatives that are required to be bifurcated from their host contract are evaluated and valued separately from the debt instrument. Under the Company’s loan agreement with HCRP, upon the occurrence of a default or a change in control, the Company may be required to make mandatory prepayments of the borrowings. The prepayment premium is considered an embedded derivative, as the holder of the loans may exercise the option to require prepayment by the Company. Further, in the event of a regulatory change that results in a material adverse effect on HCRP’s rate of return, the Company shall pay directly to HCRP an amount that compensates HCRP for such reduction. The embedded derivative is presented as a component of other non-current liabilities. The Company will remeasure the embedded derivatives each reporting period and report changes in the estimated fair value as gains or losses in interest and other income, net, in the condensed consolidated statement of operations.

Basic and Diluted Net Loss Per Share
Basic net loss per share is based upon the weighted average number of common shares outstanding during the period. Diluted net loss per share is based upon the weighted average number of common shares outstanding and dilutive common stock equivalents outstanding during the period. Common stock equivalents are options granted under the Company’s stock awards plans and are calculated under the treasury stock method. Common equivalent shares from unexercised stock options and unvested restricted stock units are excluded from the computation when there is a loss as their effect is anti-dilutive, or if the exercise price of such options is greater than the average market price of the stock for the period. The Company incurred net losses for all periods presented and there were no reconciling items for potentially dilutive securities. For the three and nine months ended September 30, 2017, approximately 6,206,000 and 6,002,000, respectively, shares of potentially dilutive securities were excluded from the computation of diluted net loss per share as their effect would have been anti-dilutive. For the three and nine months ended September 30, 2016, approximately 5,523,000 and 5,535,000, respectively, shares of potentially dilutive securities were excluded from the computation of diluted net loss per share as their effect would have been anti-dilutive.
Stock-Based Compensation
The Company accounts for stock-based compensation of stock options granted to employees and directors and for employee stock purchase plan shares by estimating the fair value of stock-based awards using the Black-Scholes option-pricing model. The Company accounts for stock-based compensation of restricted stock units granted to employees based on the closing price of the Company’s common stock on the date of grant. The fair value of stock-based awards is recognized and amortized over the applicable vesting period. All stock options awarded to non-employees are accounted for at the fair value of the consideration received or the fair value of the equity instrument issued, as calculated using the Black-Scholes model. Stock options granted to non-employees are subject to periodic revaluation at each reporting date as the underlying equity instruments vest. 
In order to estimate the value of share-based awards, the Company uses the Black-Scholes model, which requires the use of certain subjective assumptions. The most significant subjective assumptions are management’s estimates of the expected volatility and the expected term of the award. In addition, judgment is also required in estimating the amount of share-based awards that are expected to be forfeited. If actual results differ significantly from any of these estimates, stock-based compensation expense and the Company’s results of operations could be materially impacted.

3.     FAIR VALUE MEASUREMENTS
In accordance with ASC 820-10, Fair Value Measurements and Disclosures, the Company determines the fair value of financial and non-financial assets and liabilities using the fair value hierarchy, which establishes three levels of inputs that may be used to measure fair value, as follows:
Level 1 inputs, which include quoted prices in active markets for identical assets or liabilities;
Level 2 inputs, which include observable inputs other than Level 1 inputs, such as quoted prices for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. For available-for-sale securities, the Company reviews trading activity and pricing as of the measurement date. When sufficient quoted pricing for identical securities is not available, the Company uses market pricing and other observable market inputs for similar securities obtained from various third-party data providers. These inputs either represent quoted prices for similar assets in active markets or have been derived from observable market data; and
Level 3 inputs, which include unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the underlying asset or liability. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies, or similar valuation techniques, as well as significant management judgment or estimation.

Money market funds are highly liquid investments and are actively traded. The pricing information on these investment instruments are readily available and can be independently validated as of the measurement date. This approach results in the classification of these securities as Level 1 of the fair value hierarchy.
Corporate debt, and U.S. Treasury notessecurities, and commercial paper are measured at fair value using Level 2 inputs. The Company reviews trading activity and pricing for these investments as of each measurement date. When sufficient quoted pricing for identical securities is not available, the Company uses market pricing and other observable market inputs for similar securities obtained from various third partythird-party data providers. These inputs represent quoted prices for similar assets in active markets or these inputs have been derived from observable market data. This approach results in the classification of these securities as Level 2 of the fair value hierarchy. In certain cases where there is limited activity or less transparency around inputs to valuation, the related assets or liabilities are classified as Level 3. The Company classified an embedded derivative related to the Company’s Royalty-Backed Loan with HCRP as a Level 3 liability.
The fair value of the embedded derivative as a result of a change in control was calculated using a probability-weighted discounted cash flow model. The model used in valuing this embedded derivative requires the use of significant estimates and assumptions including but not limited to: 1) expected cash flows the Company expects to receive on U.S. net sales of GOCOVRI and on royalties from Allergan on U.S. net sales of Namzaric®;Namzaric; 2) the Company’s risk adjusted discount rates; 3) the probability of receipt of orphan drug exclusivity for GOCOVRI for the treatment of dyskinesia in patients with Parkinson’s disease; and 4)3) the probability of a change in control occurring during the term of the note based on the percentage of similar companies that were acquired over the previous five year period. Changes in the estimated fair value of the bifurcated embedded derivative are reported as gains or losses in interest and other income, net, in the condensed consolidated statement of operations. In the periods presented, the Company evaluated the embedded derivative value as a result of an event of default and the value as a result of increased costs due to a regulatory change areand considered both notto have no material value based on current assessment of probability, but could become material in future periods if a specified event of default or regulatory change became more probable than is currently estimated. See Note 8 “Long-Term Debt,”Debt” for further description.

At March 31, 2020, the embedded derivative related to the Royalty-Backed Loan was the only recurring fair value measurement with Level 3 unobservable inputs. A risk-adjusted discount rate of 21.5% and a probability of a change in control of 3.0% were applied to calculate the value of the embedded derivative. Significant increases (or decreases) in the discount rate, and significant increases (or decreases) in the probability of a change in control would result in a significantly higher (or lower) fair value measurement.
The following table sets forth a summary of the changes in the estimated fair value of the Company’s embedded derivative, which isLevel 3 liabilities measured at fair value as a Level 3 liability on a recurring basis for the three months ended March 31, 2020 and 2019 (in thousands):

4.     INVESTMENTS
The Company’s investments consist of corporate debt, and U.S. Treasury notessecurities, and commercial paper classified as available-for-sale securities.
The Company limits the amount of investment exposure as to institution, maturity, and investment type. To mitigate credit risk, the Company invests in investment grade corporate debt, U.S. Treasury securities, and United States Treasury notes.commercial paper. Such securities are reported at fair value, with unrealized gains and losses excluded from earnings and shown separately as a component of accumulated other comprehensive loss within stockholders’ equity. Realized gains and losses are reclassified from other comprehensive loss to other income (expense) on the condensed consolidated statements of operations when incurred. The Company may pay a premium or receive a discount upon the purchase of available-for-sale securities. Interest earned and gains realized on available-for-sale securities and amortization of discounts received and accretion of premiums paid on the purchase of available-for-sale securities are included in investment income.

In November 2012, the Company granted Forest Laboratories Holdings Limited “Forest”, an indirect wholly-owned subsidiary of Allergan plc (collectively “Allergan”) an exclusive license, with right to sublicense, certain of the Company’s intellectual property rights relating to human therapeutics containing memantine in the United States. In connection with these rights, Allergan markets and sells Namzaric® and Namenda XR® for the treatment of moderate to severe dementia related to Alzheimer’s disease.
Pursuant to the agreement, Allergan made an upfront payment of $65.0 million. The Company earned and received additional cash payments totaling $95.0 million upon achievement by Allergan of certain development and regulatory milestones. Under the agreement, external costs incurred related to the prosecution and litigation of intellectual property rights are reimbursable. For the nine months ended September 30, 2017 and 2016, reimbursed expenses amounting to zero and $2.4 million, respectively,Reimbursable external costs are reflectedrecorded as a reduction to selling, general and administrative, net. For the three months ended March 31, 2020 and 2019, there were 0 reimbursable external costs for prosecution or litigation of intellectual property rights.
In addition, the Company may earn tiered royalty payments based on future net sales of Namzaric® and Namenda XR®

Allergan’s obligation to pay royalties with respect to fixed-dose memantine-donepezil products, including Namzaric,®, continues until the later of (i) 15 years after the commercial launch of the first fixed-dose memantine-donepezil product by Allergan in the United States or (ii) the expiration of the Orange Book listed patents for which Allergan obtained rights from the Company covering such product. Allergan’s obligation to pay royalties with respect to Namenda XR® continues until the expiration of the Orange Book listed patents covering such products. However, Allergan’s obligation to pay royalties for any product, covered by the licensebut is eliminated in any quarter where there is significant competition from generics. Based on Allergan��s and the Company’s current settlement agreements with the Namzaric ANDA filers to date, the Company anticipates it will be entitled to royalties on Allergan’s sales of Namzaric to continue through December 31, 2024, or in the alternative, an option to launch an authorized generic version of Namzaric through December 31, 2025, or earlier in certain circumstances. For further discussion of Namzaric ANDA filers, see Litigation and Other Legal Proceedings in “Note 7 – Commitments and Contingencies”. Beginning in June 2018, the Company was entitled to receive royalties at rates in the low to mid-single digits for sales of Namenda XR in the United States. The Company does not expect to receive royalties on net sales of Namenda XR, due to the entry of generic versions of Namenda XR. Royalties under the license agreement will be recognized when the related sales occur, in accordance with the sales-based royalty exception.

8.     LONG-TERM DEBT
Royalty-Backed Loan Agreement
In May 2017, the Company, through a new wholly-owned subsidiary, Adamas Pharma, LLC, entered into a Royalty-Backed Loan with HCRP, whereby the Company initially borrowed $35.0$35 million, and will borrowfollowed by an additional $65.0$65 million received in the fourth quarter 2017 upon FDA approval and whenFDA’s recognition in the FDA’s Orange Book is updated to recognize the 7-yearof seven-year orphan drug exclusivity, which GOCOVRI earned upon approval on August 24, 2017. Principal and interest will be payable quarterly from the proceeds of a 12.5% royalty on U.S. net sales of GOCOVRI and up to $15.0$15 million of the Company’s annual royalties from Allergan on U.S. net sales of Namzaric® starting in May 2020, pursuant to the Company’s license agreement with Allergan. The royalty rate on net sales of GOCOVRI will drop to 6.25% after the principal amount of the loan has been repaid in full, until the Company has made total payments of 200% of the funded amounts. The Company may elect to voluntarily prepay the loan at any time, or may be required to prepay subject to specified prepayment trigger events as described below, in which case the amount due will be 200% of the funded amounts, less total payments made to date. Royalty rates are subject to increase to 17.5% and 22.5% if total principal and interest payments have not reached minimum specified levels at measurement dates on December 2021 and December 2022, respectively. Under the terms of the loan, HCRP has recourse to Adamas Pharma, LLC, not the Company. The loan agreement matures in December 2026 but as the repayment of the loan amount is contingent upon the sales volumes of GOCOVRI and royalties from Allergan, the repayment term may be shortened depending on the actual sales of GOCOVRI and actual royalties received from Allergan.
The loans bear interest at an annual rate of 11% on the outstanding principal amount and includes an interest-only period until the interest payment date following the ninth full calendar quarter after the earlier of the $65.0$65 million additional loan or October 2018.

received in the fourth quarter 2017. The interest-only period ended during the first quarter of 2020. To the extent that royalties arewere insufficient to pay interest in full during the first nine quarters of the loan, any unpaid portion of the quarterly interest payment will bewas added to the principal amount of the loans. For the three and nine months ended September 30, 2017, accrued interest in the amount of $1.6 million and $2.3 million was added to the principal balance of the loan.
In connection with the Royalty-Backed Loan, in 2017 the Company paid HCRP a lender expense amount of $0.4 million and incurred additional debt issuance costs totaling $0.8 million. The lender expense and additional debt issuance costs have been recorded as a debt discount and are being amortized and recorded as interest expense over the estimated term of the loan using the effective interest method. The Company recorded interest expense, including amortization of the debt discount, related to the Royalty-Backed Loan, of $1.7$3.6 million and $2.4$3.7 million for the three and nine months ended September 30, 2017.March 31, 2020 and March 31, 2019, respectively. Interest expense over the life of the Royalty-Backed Loan includes an annual interest rate of 11% on the outstanding principal, a royalty rate of 6.25% on net sales of GOCOVRI after the principal amount is paid, and amortization of the debt discount. The effective interest rate as of September 30, 2017March 31, 2020 on the amounts borrowed under the Royalty-Backed Loan, including the amortization of the debt discount, was 20.6%13.4%.
The assumptions used in determining the expected repayment term of the loan and amortization period of the debt discount require that wethe Company make estimates that could impact the short and long-term classification of these costs, as well as the period over which these costs will be amortized and the effective interest rate.
The Company may be required to make mandatory prepayments of the borrowings under the Royalty-Backed Loan subject toupon the occurrence of specified prepayment trigger events, including: (1) the occurrence of any event of default or (2) the occurrence of a change in control. Upon the prepayment of all or any of the outstanding principal balance, the Company shall pay, in addition to such prepayment, a prepayment premium. As HCRP, as the holder of the loans, may exercise the option to require prepayment by the Company, the prepayment premium is considered to be an embedded derivative which is required to be bifurcated from its host contract and accounted for as a separate financial instrument. The valuation of the embedded derivative is described further in Note 3.

ITEM 2.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
You should read the following discussion and analysis of our financial condition and results of operations together with ourcondensed consolidatedfinancial statements and related notes included elsewhere in this report. This discussion and other parts of this report contain forward-looking statements that involve risk and uncertainties, such as statements of our plans, objectives, expectations and intentions.intentions, and the expected impact that the COVID-19 pandemic will continue to have on our business. Our actual results could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section of this report entitledtitled “Risk factors.”
Overview
At Adamas wePharmaceuticals, Inc., our purpose is to make everyday life significantly better for people affected by neurological diseases. We are turning this purpose into reality by combining our proven expertise in discovery, development and commercialization with our passion for improving lives. We believe in the power and the promise of medicines derived from a deep understanding of time-dependent biology. All biological processes, including the body’s responses to disease and drug interventions, are governed by complex timing patterns. When the timing of disease and drug responses are out of sync, patient outcomes can be compromised.
Our expertise lies in uncovering and mapping the relationship between disease and drug activity timing patterns. From there, we strive to create medicines with therapeutic profiles that match the pattern of disease to drive a significant and durable clinical effect. As a result, our medicines should be clinically differentiated and provide a meaningful benefit to patients. With one partnered product and a commercial medicine, we are designedfocused on growing a portfolio of therapies to providereduce the burden of neurological diseases on patients, with what they need, when they need it - the right level of drug at the right placecaregivers, and time to enhance efficacy - and then lower levels of drug when they don’t need it. Our goal is to develop medicines that are timed for the benefit of patients.society.
Our understanding of time-dependent biological processes informs our every innovation, targeting advancement in treatment of chronic neurologic disorders. Our portfolio includes:
GOCOVRITM (amantadine) extended release capsules, formerly referred to as ADS-5102, for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications;
ADS-5102Approved Product:
GOCOVRI® (amantadine) extended release capsules, (GOCOVRI) in development foris the treatment of walking impairment in patients with multiple sclerosis;
ADS-4101 (lacosamide) modified release capsules in development for the treatment of partial onset seizures in patients with epilepsy;first and
Namzaric® (memantine hydrochloride extended release and donepezil hydrochloride) capsules and Namenda XR® (memantine hydrochloride) extended release capsules for the treatment of moderate to severe Alzheimer’s disease.
Individual products in Adamas’ portfolio and their proposed indications are protected by an array of intellectual property, including robust and diversified patent claims, and regulatory exclusivities. For example, GOCOVRI is protected by 7-year orphan drug exclusivity, 3-year new product exclusivity, and issued patents and pending patent applications out to at least 2035.
GOCOVRI (formerly referred to as ADS-5102) for the Treatment of Dyskinesia in Patients with Parkinson’s Disease
On August 24, 2017, the U.S. Food and Drug Administration (“FDA”) approved our new drug application (“NDA”) for GOCOVRI (amantadine) extended release capsules only FDA-approved medication indicated for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications (“dyskinesia”). GOCOVRImedications. It is also the first and only FDA-approved medicine for this indication, and GOCOVRI earned 7-years of orphan exclusivity upon its approval. GOCOVRI is a high-dose 274-mg amantadine taken once-daily at bedtime that delivers high levels of amantadine in the morning and throughout the day when dyskinesia occurs. We made GOCOVRI available for physician and patient use in the fourth quarter of 2017, with plans for a full commercial launch via the deployment of our sales team in January 2018.

Parkinson’s disease is a chronic neurodegenerative disorder affecting closeclinically proven to 1 million people in the United States. Levodopa, which replaces lost dopamine, is considered the “gold standard” and the most effective therapy for Parkinson’s disease. Over time, people with Parkinson’s disease require increasingly higher or more frequent doses of levodopa to avoid recurrent periods of OFF time - characterized by slowness of movement, rigidity, impaired walking, tremor, and postural instability - when the underlying symptoms of Parkinson’s disease return. At this stage, Parkinson’s disease is characterized by an over-activated glutamate system, which may contribute to motor complications (dyskinesia and OFF). As Parkinson’s disease progresses, approximately 90 percent of people on levodopa therapy will experience dyskinesia, which is characterized by involuntary movements that are non-rhythmic, purposeless, and unpredictable, impacting peoples’ daily lives. Approximately 150,000 to 200,000 Parkinson’s disease patients in the United States suffer with dyskinesia.
In a robust clinical program consisting of three randomized placebo-controlled studies and a two-year, ongoing, open label safety study, GOCOVRI demonstrated a durable reduction inreduce both dyskinesia and OFF time in peoplethat population. GOCOVRI was approved for marketing by the U.S. Food and Drug Administration, or FDA, on August 24, 2017, with Parkinson’s disease.seven years of orphan exclusivity and additional patent protections out to 2034.On January 2, 2020, we announced we had granted Sandoz Inc. a license for its generic version of GOCOVRI as of March 4, 2030, or earlier in certain circumstances typical for such agreements.
Potential Additional Indication for GOCOVRI (amantadine) Extended Release Capsules (ADS-5102):
ADS-5102 (GOCOVRI) in Developmentdevelopment for the Treatmenttreatment of Walking Impairmentwalking impairment in Patientspatients with Multiple Sclerosis
ADS-5102 is an investigational high-dose, extended release amantadine taken once-daily at bedtime. We completed a Phase 2 proof-of-concept study designed to evaluate ADS-5102 in multiple sclerosis (“MSW”). We announced the topline results from INROADS Phase III trial of ADS-5102 on December 17, 2019.The study met its primary endpoint, showing a potential benefit for patients with walking impairment. A 17% improvement in walking speed versus placebo was observed inWe are conducting market research, further analyzing the timed 24 foot walk. The results for timed-up-and-goINROADS Phase III data, including evaluating the ongoing, open-label extension study, and 2-minute walking test also suggested benefit on other aspects of mobility and walking.
We plan to initiate a Phase 3 clinical program of ADS-5102 for multiple sclerosis patients with walking impairment in the first quarter of 2018, based on the data from the Phase 2 trial and feedback we received from our End-of-Phase 2 meeting with the FDA.
Additional Indications for GOCOVRI
We intend to continue to review the results of preclinical studies, clinical trials, and case reports published in peer reviewed medical journals to evaluate additional potential CNS indications for GOCOVRI, including upstream indications in Parkinson’s disease and other hyperkinetic movement disorders.
ADS-4101 in Development for the Treatment of Partial Onset Seizures in Patients with Epilepsy
ADS-4101 is an investigational high-dose, modified release lacosamide capsule, taken once-daily at bedtime. Lacosamide is an anti-epilepsy active ingredient previously approved by the FDA and currently marketed by UCB SA/NV as VIMPAT® (lacosamide). ADS-4101 was designed to temper the initial rate-of-rise in lacosamide concentrations, potentially improving the adverse event profile and dose limitations due to dizziness following administration of VIMPAT. The slow initial rise may enable a higher once-daily dose at bedtime, which results in a higher daytime concentration that may be more effective for patients than VIMPAT.
We have completed two Phase 1 studies of ADS-4101 in healthy volunteers. The Phase 1a study showed that a single 400 mg dose of ADS-4101 was better tolerated compared to the equivalent dose of VIMPAT immediate release tablets. The data also demonstrated that ADS-4101 exhibited the desired pharmacokinetic properties, namely a reduced rate of initial rise and delayed time to maximum drug concentration (Tmax) appropriate for bedtime dosing. The recently completed and reported results of a multi-dose Phase 1b study demonstrated that a 600 mg dose of ADS-4101, taken once-nightly, provided a 1.5 to 2.5-fold increase in average lacosamide concentrations throughout the day compared to the maximum approved daily dose of 400 mg, taken as 200 mg twice-daily (BID), of VIMPAT immediate release tablets in healthy volunteers, with comparable tolerability.
We expect to meetengaging with the FDA at an End-of-Phase 2 meeting regarding our planned Phase 3 clinicalto determine a potential path forward for the program by the end of the second quarter of 2020.

Impact of the COVID-19 pandemic on our company
The outbreak of the novel Coronavirus (“Allergan”COVID-19”), which is understood to have begun in December 2019, continues to grow both within the U.S. and globally. The World Health Organization has declared the outbreak of COVID-19 to be a pandemic, and the U.S. federal government has declared it a national emergency.
How we are operating in the United States for the treatment of moderate to severe Alzheimer's disease. current COVID-19 shutdown
We are eligiblecommitted to receive royaltiesthe health and safety of our employees and their families and doing our part to slow the community spread of COVID-19. In mid-March, we implemented a number of actions, including a work-from-home policy for all our employees, allowing for flexible work schedules, and restrictions on in-person meetings. We are very proud of our entire team as we transitioned swiftly to working remotely. We are following the guidelines of the Centers for Disease Control and other federal, state and local authorities and will continue to assess when it is appropriate for our team to return to normal work practices.
Impact on our ability to sell GOCOVRI
We continue to see stable GOCOVRI prescription refill rates due to our continued strong patient persistence, adequate supply of GOCOVRI, and patient access to GOCOVRI through distribution from our specialty pharmacy directly to a patient’s home. However, we have seen that new prescription rates have slowed due to several factors, including: many healthcare providers have temporarily closed their offices or are restricting patient visits; patients are postponing visits to healthcare provider facilities; and our sales force has moved to conducting activities virtually with healthcare providers. While we believe this decline in new prescriptions to be temporary, the duration and severity is dependent on future developments, which are highly uncertain and cannot be predicted with confidence.
Impact on our supply chain
Our GOCOVRI supply chain remains robust and thus far we have observed no disruptions to our inventory on hand or our planned manufacturing schedule. We have an adequate supply of Namenda XR®GOCOVRI to address patients’ needs into late 2021 with our recently completed manufacturing campaign. Based on current information, we believe that our partners in our supply chain have been and Namzaric® beginningwill continue to operate during the current COVID-19 outbreak.
Impact on our financial condition and capital resources
The extent of the impact of COVID-19 on our business, financial results, liquidity and cash flows will depend largely on future developments, including new information that may emerge concerning the severity and duration of actions taken to contain or prevent further spread. With already imposed shelter-at-home orders in Juneplace, we have observed widespread closure of 2018clinics, and Maycancellation or rescheduling of patient appointments have been combined with restriction of access to sales representatives in some institutions and a marked increase in telemedicine consultations that may result in further sales reductions. As of March 31, 2020, respectively.we had cash, cash equivalents, and investments of $115.3 million, and $50.0 million of availability to sell common stock under our sales agreement with Cowen and Company, LLC.
Financial operations overview
Summary
Our revenue through September 30, 2017, has been generated primarily from license, milestone, and development revenue pursuant to our license agreement with Allergan. We have not generated any commercial product revenue through September 30, 2017; however, we received approval for GOCOVRI on August 24, 2017. We made GOCOVRI available for physician and patient use in the fourth quarter of 2017, with plans for a full commercial launch via the deployment of our sales team in January 2018. As of September 30, 2017,March 31, 2020, we had an accumulated deficitcash, cash equivalents, and available-for-sale securities of $182.3$115.3 million. Although we reported net income in each of the years ended December 31, 2014, 2013, and 2012, this was primarily due to the recognition of revenue pursuant to our license agreement with Allergan. ThereWe are no further milestone payments to be earned under our license agreement with Allergan. We incurred significant losses in the nine months ended September 30, 2017, and in the years 2016, 2015, and prior to 2012, and expect to continue to incur significant losses as we support the commercialization of GOCOVRI and advance our product candidates into later stages of development and commercialization.
We plan to commercializecommercializing GOCOVRI through our owndeployed sales force targeting neurologists and movement disorder specialists in the United States, and possibly through partnership agreements with pharmaceutical companies outside the United States. Consequently, we expect selling, general and administrative expenses to increase as we approach full product commercializationAs of GOCOVRI in January 2018. In addition, we expect to continue to incur significant research and development expenses as we continue to advance our product candidates through clinical development. Because of the numerous risks and uncertainties associated with drug development and commercialization, we are unable to predict the timing or amount of expenses incurred or when, or if, we will be able to achieve or maintain profitability.
Under our agreement with Allergan, beginning in MayMarch 31, 2020, we are entitled to receive tiered royalties in the low to mid-teens for net saleshad an accumulated deficit of Namzaric® in the United States. $464.5 million.
In addition, we are also entitled to receive tiered royalties in the low to mid-single digits from Allergan for net sales of Namenda XR® in the United States beginning in June 2018; however, we do not expect the Namenda XR® royalties will make a significant financial contribution to our business. Pursuant to the agreement, we received a non-refundable upfront license fee of $65.0 million in 2012, which we recognized on a straight-line basis from November 2012 to February 2013. We also earned and received additional cash payments totaling $95.0 million upon achievement by Allergan of certain development and regulatory milestones, which we recognized in 2013 and 2014.
Prior to our initial public offering of our common stock, or IPO, in April 2014, we had raised an aggregate of approximately $87.2 million through the sale of convertible preferred stock and $1.0 million through the exercise of preferred stock warrants. In 2014, we issued and sold 3,081,371 shares of common stock in our IPO and received net proceeds of approximately $42.6 million, which included partial exercise of the underwriters’ option to purchase additional shares and after deducting underwriting discounts and offering expenses. In connection with the completion of our IPO, all convertible preferred stock converted into common stock. In June 2015, we entered into a Controlled Equity Offering Sales Agreement, pursuant to which we were able to issue and sell shares of common stock having an aggregate offering value of up to $25.0 million, which was terminated in November 2016. During the term of the agreement, we issued 509,741 shares of common stock and raised net proceeds of $9.7 million. In January 2016, we raised $61.8 million from the sale of 2,875,000 shares of common stock in a follow-on public offering. In May 2017,2019, we entered into a sales agreement with Cowen and Company, LLC, pursuant to which we may, from time to time, issue and sell shares of common stock having an aggregate offering value of up theto $50.0 million. As of September 30, 2017, noMarch 31, 2020, we have not sold any shares have been sold under the sales agreement. Also in May 2017, we entered into a royalty-backed loan agreement (“Royalty-Backed Loan”) with HealthCare Royalty Partners (“HCRP”), whereby we borrowed $35.0 million and will borrow an additional $65.0 million upon
Revenue
Product sales consist of sales of GOCOVRI, which was approved by the FDA approval and FDA’s recognition in the Orange Book of the 7-year orphan drug exclusivity that GOCOVRI earned upon approval on August 24, 2017. We began commercial sales of GOCOVRI in the fourth quarter of 2017, forand initiated the treatmentfull commercial launch via the deployment of dyskinesiaour sales team in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications. The FDA has already recognized GOCOVRI’s orphan drug exclusivity by letterJanuary 2018.

Asthe generation of September 30, 2017, we had cash, cash equivalents, and available-for-sale securities of $130.7 million.
Revenue
We have not generated any revenue from commercial product sales to date. Ourfrom GOCOVRI, our revenue to date hashad been generated primarily from payments under our license agreement with Allergan for non-refundable upfront license payments, milestone payments and reimbursements for research and development expenses andfor full-time equivalentsequivalent employees assigned under ourto the license agreement with Allergan, and to a lesser degree reimbursement for research and development expenses from NIH grants and government contracts. We do not expect to recognize anyagreement. There are no further milestone payments to be earned under our license agreement with Allergan, and we expect reimbursements for full-time equivalents assigned to the license agreement to be inconsequential in future periods. Beginning in May 2020, we will beare entitled to receive tiered royalties from Allergan in the low double digits to mid-teens, from Allergan foras a percent of net sales of Namzaric® in the United States,States. Based on 2019 net sales of Namzaric, we expect the tiered royalty to be in the low double digits through the term of the agreement, but is eliminated in any quarter where there is significant competition from generics. Based on Allergan’s and in June 2018our current settlement agreements with the Namzaric ANDA filers to date, we anticipate we will be entitled to receive royalties on Allergan’s sales of Namzaric to continue through December 31, 2024, or in the lowalternative, an option to mid-single digitslaunch an authorized generic version of Namzaric through December 31, 2025, or earlier in certain circumstances. For further discussion of Namzaric ANDA filers, see Litigation and Other Legal Proceedings in “Note 7 – Commitments and Contingencies”.
Cost of product sales
Cost of product sales consists primarily of direct and indirect costs related to the manufacturing of GOCOVRI products sold, including third-party manufacturing costs, packaging services, freight, allocation of overhead costs, and inventory adjustment charges. We began capitalizing inventory manufactured at the FDA approved locations upon FDA approval of GOCOVRI and upon FDA approval of a supplemental NDA for net sales of Namenda XR® ina second manufacturing site with our current third-party manufacturer. We recorded inventory acquired prior to the United States; however, we do not expect the Namenda XR® royalties will make a significant financial contribution to our business. We were also awarded a continuation of an NIH grant for $1.0 million in August 2014 that terminated in July 2016, which we administered, but conducted through subcontractors.regulatory approvals as research and development expense.
Research and development expenses
Research and development expenses represent costs incurred to conduct research, such as the discovery and development of our wholly-owned product candidates and, to a lesser degree, the development of product candidates pursuant to our agreement with Allergan.candidates. We recognize all research and development costs as they are incurred.
Research and development expenses consist of:
fees paid to clinical investigators, clinical trial sites, consultants, and vendors, including contract research organizations, or CROs, in conjunction with implementing, conducting, and monitoring our clinical trials and acquiring and evaluating clinical trial data, including all related fees, such as for investigator grants, patient screening fees, laboratory work, and statistical compilation and analysis;
expenses related to production of clinical supplies, including fees paid to contract manufacturing organizations, or CMOs;
expenses related to establishment and validation of manufacturing capabilities for commercial supply,supply;
expenses related to the buildup of commercial supply to support commercial launch, prior to FDA approval,approval;
expenses related to compliance with regulatory requirements;
other consulting fees paid to third parties; and
employee-related expenses, which include salaries, benefits, and stock-based compensation.

(2)We reduced investments in ADS-4101 in the quarter ended June 30, 2019.
The program-specific expenses summarized in the table above include costs directly attributable to our product candidates. Other research and development expenses include costs for early stage programs and costs not allocated to a specific program. We allocate research and development salaries, benefits, stock-based compensation, and indirect costs to our product candidates on a program-specific basis, and we include these costs in the program-specific expenses. We

begin to track and report program-specific expenses for early stage programs once they have been nominated and selected for further development and clinical-stage work has commenced.
Our investment in research and development activities, including the clinical development of our product candidates, has historically represented a significant portion of our total operating expenses. We anticipate incurring significanthave concluded the two-year Phase 3 open-label study of GOCOVRI and suspended investment in the development of ADS-4101. Our research and development expenses as we continue to support: clinical trialsefforts are focused on completing activities for ADS-5102 (GOCOVRI) in indications beyond dyskinesia in patients with Parkinson’s disease,for MSW, including but not limitedadditional analyses of the data from the INROADS trial and continuing the open-label extension study through the end of 2020. As a result, we expect research and development costs to walking impairment in multiple sclerosis patients and other Parkinson’s disease indications earlier indecrease from 2019 levels for the Parkinson’s disease treatment journey; ADS-4101 for treatment of epilepsy; and potentially additional clinical-stage programs in more indications or forforeseeable future, product candidates. based on this focused strategy.
The process of conducting the necessary clinical research to obtain FDA approval is costly and time consuming. We consider the active management and development of our clinical pipeline to be crucial to our long-term success. The actual probability of success for each product candidate and clinical program may be affected by a variety of factors, including but not limited to, the quality of the product candidate, early clinical data, investment in the program, competition, manufacturing capability, and commercial viability. Furthermore, in the past we have entered into licensing arrangements with other pharmaceutical companies to develop and commercialize our product candidates, and we may enter into additional licensing arrangements or collaborations in the future. In situations in which third parties have control over the clinical development of a product candidate, the estimated completion dates are largely under the control of such third parties and not under our control. We cannot forecast with any degree of certainty which of our product candidates, if any, will be subject to future licensing or collaboration arrangements or how such arrangements would affect our development plans or capital requirements. As a result of the uncertainties discussed above, we are unable to determine the duration and completion costs of our research and development projects or when and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.
Selling, general and administrative expenses, net
Selling, general and administrative expenses, net, consist primarily of personnel and related benefit costs, including stock-based compensation, facilities, professional services, insurance, and public company related expenses, charitable contribution expenses, as well as increasingly the costs associated with establishing commercial capabilities in support ofsupporting the commercialization of GOCOVRI, reduced to a small degree by reimbursement from Allergan for external costs related to supporting prosecution and litigation of intellectual property rights under our license agreement. We anticipate our selling, general and administrative expenses will remain significant and may increase significantly as we continue to establish our commercial capabilities and support our potential commercial-stage programs. We plan to market and sell GOCOVRI through our own sales force with support from a contract sales organization for certain functions, targeting neurologists and movement disorder specialists in the United States.commercialization of GOCOVRI.
Interest and other income, (expense), net
Interest and other income, (expense), net, consists primarily of a changechanges in fair value of the embedded derivative liability related to our royalty-backed loan agreement (“Royalty-Backed Loan”) with HCRP,HealthCare Royalty Partners III, L.P., (“HCRP”), in addition to interest received on our investments.
Interest expense
Interest expense consists of accrued interest pursuant to our Royalty-BasedRoyalty-Backed Loan and amortization of debt issuance costs. Interest expense accrues using the effective interest rate method over the estimated period the debt is expected to be repaid. Interest expense over the life of the Royalty-Backed Loan includes an annual interest rate of 11% on the outstanding principal, a royalty rate of 6.25% on net sales of GOCOVRI after the principal amount is paid, and amortization of the debt discount, until a maximum aggregate repayment amount has been reached.

Critical accounting policies and significant judgments and estimates
Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with United States generally accepted accounting principles, or U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenue generated and expenses incurred during the reporting periods. OurWe base our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. We have discussed the development, selection, and disclosure of these estimates with the Audit Committee of our Board of Directors. Actual results may differ from these estimates under different assumptions or conditions. Refer to “Note 2 - Summary of Significant Accounting Policies”in the accompanying “Notes to Condensed Consolidated Financial Statements (unaudited),” which information is incorporated

Results of operations
Fluctuations in Operating Results
Our results of operations have fluctuated from period to period in the past and, especially in light of the COVID-19 pandemic, are likely to continue to do so in the future. We anticipate that our quarterly and annual results of operations will be impacted for the foreseeable future by several factors, including the impact on our operations as a result of the COVID-19 pandemic, fluctuations in product sales due to variances in the number of paid prescriptions from period to period, conversions from our free drug trial program to paid prescriptions, and fluctuations in our Medicare Part D Coverage Gap liability and the volume of purchases eligible for government mandated discounts and rebates, as well as changes in discount percentages that may be impacted by potential future price increases and other factors. Further, we expect the timing of expenditures related to our commercial activities associated with GOCOVRI to vary from period to period, as well our development of ADS-5102 in additional indications and potential development of additional product candidates. Due to these fluctuations, we believe that the period to period comparisons of our operating results are not necessarily a good indication of our future performance.

Cost of product sales
Cost of product sales increased by $0.2 million to $0.6 million, or 4% of product sales, for the three months ended March 31, 2020, from $0.4 million, or 4% of product sales, for the three months ended March 31, 2019. Cost of product sales for the three months ended March 31, 2020 includes a provision for the write-down of inventory of $0.3 million. We received regulatory approval for GOCOVRI from the FDA in August 2017.

The decrease was offset in part by increased activity related to clinical work associated withthe decision during the second quarter of 2019 to defer additional investment in the development of our product candidate ADS-4101 for the treatment of partial onset seizures in patients with epilepsy. Included in research and development expenses was stock-based compensation expense, which was $0.8 million compared to $0.7$0.1 million for the three months ended September 30, 2017 and 2016, respectively.

The decrease in research and development expenses was mainly attributable to costs associated with the clinical development of GOCOVRI for the treatment of dyskinesia in patients with Parkinson’s disease due to the conclusion of two Phase 3 clinical trials, in addition to costs associated with the ongoing open-label safety study which also decreased from the prior year. The decrease was offset by increased activity related to clinical work associated with ADS-4101 for the treatment of partial onset seizures in patients with epilepsy. Included in research and development expenses was stock-based compensation expense, which was $2.6 million compared to $2.1 million for the nine months ended September 30, 2017 and 2016, respectively.
We began capitalizing inventory manufactured at the FDA approved location upon FDA approval of GOCOVRI in August 2017. Inventory acquired prior to the regulatory approval was recorded as research and development expense. We expect to use inventory expensed to research and development over approximately the next two years, and accordingly we would expect our cost of GOCOVRI product sales to increase as a percentage of net sales of GOCOVRI in future periods.

The increaseMarch 31, 2019, primarily due to decreased legal fees, personnel related costs including mainly stock-based compensation, other professional services, and general corporate expense. Included in selling, general and administrative expenses was primarily due to increased costs associated with establishing commercial capabilities in anticipation of the commercialization of GOCOVRI, including an increase in headcount-related expenses and commercial activities.

The increasedecrease in interest and other income, net, in the three months ended March 31, 2020, was primarily duedriven by lower interest income earned on lower cash and investment balances.
Interest expense
Interest expense was $3.6 million for the three months ended March 31, 2020, compared to $3.7 million for the three months ended March 31, 2019. The decrease in interest expense was mainly related to a change in fair value of the embedded derivative liability related tolower estimated effective interest rate on our Royalty-Backed Loan with HCRP.

Interest expense
The increase in interest expense to $1.7 million and $2.4 million for the three and nine months ended September 30, 2017, compared to zero in the three and nine months ended September 30, 2016, was due to the new Royalty-Backed Loan entered into in May 2017.

WeSince January 1, 2017, we have funded our operations primarily through $160.0 million of payments received pursuant to our license agreement with Allergan, $88.2 million sales of convertible preferred stock and warrants, $114.1 million pursuant to sales of our common stock and $35.0sales of GOCOVRI, as well as we borrowed $100 million pursuant tounder our Royalty-Backed Loan with HCRP.
In April 2014, we completed our IPO and raised net proceeds of $42.6 million, including the underwriters’ partial exercise of their option to purchase additional shares.

We made GOCOVRI available for physician and raised net proceeds of $9.7 million. In January 2016, we completed a follow-on public offering of 2,875,000 shares of common stock, which includes the exercise in full by the underwriters of their option to purchase 375,000 shares of common stock, at an offering price of $23.00 per share. Proceeds from the follow-on public offering were approximately $61.8 million, net of underwriting discounts and offering-related transaction costs. In May 2017, we entered into a Royalty-Backed Loan with HCRP, whereby we initially borrowed $35.0 million and will borrow an additional $65.0 million upon FDA approval and FDA’s recognitionpatient use in the Orange Bookfourth quarter of 2017, with a full commercial launch via the 7-year orphan drug exclusivity thatdeployment of our sales team in January 2018. Prior to the generation of revenue from GOCOVRI, earned upon approval on August 24, 2017, for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications. The FDA has already recognized GOCOVRI’s orphan drug exclusivity by letter to us and on its Orphan Drug Designation and Approvals database listing.
We havewe had not generated any commercial revenue from the sale of products. We incurred losses and generated negative cash flows from operations since inception through the year ended December 31, 2011. Although we recognized a profit and positive cash flow from operations in 2014, 2013, and 2012 as a result of payments received pursuant to our license agreement with Allergan, we received our final milestone payment from Allergan in December 2014. We do not currently receive any royalties from Allergan, nor do we have other license agreements or collaborations from which we might expect milestone or royalty revenue. Consequently, we expect to continue to incur substantial and increasing losses for

We believe our existing cash, cash equivalents, and investments at March 31, 2020 will be sufficient to fund our projected operating requirements, including operations related to the continued development of our product candidates and commercialization of GOCOVRI for the treatment of dyskinesia in patients with Parkinson’s disease and operations related to the continued development of ADS-5102 for other indications including MSW, for at least 12 months from the next 12 months.issuance of this quarterly report on Form 10-Q. However, it is possible that we will not achieve the progress that we expect, because revenues from GOCOVRI may be less than anticipated, especially in light of the current COVID-19 pandemic, and the actual costs and timing of drug development, particularly clinical studies, and regulatory approvals are difficult to predict, subject to substantial risks and delays, and often vary depending on the particular indication and development strategy. The duration and severity of the COVID-19 pandemic is unknown and makes projecting the outcome of future developments highly uncertain and cannot be predicted with confidence. Moreover, the costs associated with commercializing drugs are high and market acceptance is uncertain.
We expect to incur substantial expenses and operating losses for the foreseeable future. We expect to continue significant spending in connection with the development and commercialization of our product candidates, particularly for the commercialization of GOCOVRI for the treatment of dyskinesia in patients with Parkinson’s disease, as well as the development of ADS-5102 for other indications, and also for ADS-4101 for indications in epilepsy, for which Phase 3 clinical trials may be initiated in 2018.potential development of additional product candidates. To continue these activities, we may decide to raise additional funds through a combination of public or private equity offerings, debt financings, royalty financings, collaborations, strategic alliances, licensing arrangements, asset sales, and other marketing and distribution arrangements. Sufficient additional funding may not be available on acceptable terms, or at all.all, especially as a result of the economic downturn occurring and expected to continue as a result of the actions taken to contain the spread of COVID-19. If adequate funds are not available in the future, we may need to delay, reduce the scope of, or put on hold our clinical studies, research and development programs, or commercialization efforts.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The primary objectiveWe are a smaller reporting company as defined by Rule 12b-2 of our investment activities isthe Securities Exchange Act of 1934 and are not required to preserve our capital to fund our operations. We also seek to maximize income from our investments without assuming significant risk. To achieve our objectives, we maintain a portfolio of cash equivalents and investments in a variety of securities of high credit quality. As of September 30, 2017, we had cash, cash equivalents, and investments of $130.7 million, compared to $135.9 million at December 31, 2016, consisting of cash and cash equivalents, as well as short and long-term investment grade available-for-sale securities. A portion of our investments may be subject to interest rate risk and could fall in value if market interest rates increase. However, because our investments are primarily short-term in duration and our holdings in US government bonds and corporate debt securities mature prior to our expected need for liquidity, we believe that our exposure to interest rate risk is not significant and, as a consequence, a one percentage point movement in market interest rates would not have a significant impact onprovide the total value of our portfolio. We actively monitor changes in interest rates.information under this item.
ITEM 4.  CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and the rules and regulations thereunder, is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
As required by Rule 13a-15(b) under the Exchange Act, our management, under the supervision and with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of September 30, 2017.March 31, 2020. Based on such evaluation, our principal executive officer and principal financial officer have concluded that, as of September 30, 2017,March 31, 2020, our disclosure controls and procedures were effective.effective at the reasonable assurance level.
Changes in Internal Control Over Financial Reporting
During the quarter ended September 30, 2017, we implemented processes and internal controls to record inventory as a result of the FDA approval of GOCOVRI. The implementation of these processes resulted in changes to internal controls over financial reporting, which we believe were material. There were no other changes in our internal control over financial reporting during the quarter ended September 30, 2017 identified in connection with the evaluation required by RuleRules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the three months ended March 31, 2020, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 1A. RISK FACTORS
We have identified the following risks and uncertainties that may have a material adverse effect on our business, financial condition, results of operations, and future growth prospects. Our business could be harmed by any of these risks. The risks and uncertainties described below are not the only ones we face. The trading price of our common stock could decline due to any of these risks, and you may lose all or part of your investment. In assessing these risks, you should also refer to the other information contained in this Quarterly Report on Form 10-Q, including our unaudited condensed consolidated financial statements and related notes.
The outbreak of the novel Coronavirus (“COVID-19”) has negatively impacted our business, including the commercialization strategy and sales of GOCOVRI® (amantadine) extended release capsules.
The outbreak of the novel Coronavirus (“COVID-19”), which is understood to have begun in December 2019, continues to grow both within the U.S. and globally. The World Health Organization has declared the outbreak of COVID-19 to be a pandemic, and the U.S. federal government has declared it a national emergency. Efforts to contain the spread of COVID-19 have intensified and the U.S. has implemented severe travel restrictions, enforced social distancing, shelter-in-place orders and delays or cancellations of physician visits. These circumstances have negatively impacted our business and the commercialization strategy of GOCOVRI, including patients postponing visits to healthcare provider facilities, healthcare providers temporarily closing their offices or restricting patient visits, and limiting the ability of our sales force to travel and meet with healthcare providers and resulting in sales and marketing being conducted virtually. In particular, we have observed a decrease in our new prescription rate, which we attribute to the effects of the restrictive actions taken.
We have implemented a work-from-home policy for all our employees, including allowing for flexible work schedules. The effects of our work-from-home policy may negatively impact productivity and disrupt our business.
These disruptions in our operations have negatively impacted, and we expect will continue to negatively impact, our business, operating results and financial condition. The COVID-19 pandemic continues to rapidly evolve. The ultimate cumulative impact of the COVID-19 pandemic on our business operations is highly uncertain, the duration and severity of which will depend on future developments, and cannot be predicted with confidence. We will continue to monitor the situation closely. The COVID-19 pandemic may also exacerbate a number of the risks discussed below.
Risks related to the commercialization of GOCOVRI and the development, regulatory approval, and commercialization of our current and future product candidates® (amantadine) extended release capsules
Our success depends heavily on successful commercializationthe success of GOCOVRI which received approval on August 24, 2017, from the U.S. Food and Drug Administration, or FDA, for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications. To the extent GOCOVRI is not commercially successful, our business, financial condition and results of operations will be materially harmed.
We have invested and continue to invest a significant portion of our efforts and financial resources intoin the development, approval and now commercialization of GOCOVRI for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications, (“dyskinesia”).medications. The success of GOCOVRI will depend on numerous factors, including:
GOCOVRI’s efficacy and safety profile;
our success in commercializing GOCOVRI, including the marketing, sales, and distribution of GOCOVRI, especially in light of the product;COVID-19 pandemic;
the duration of the COVID-19 pandemic and the stay-at-home restrictions;
28

acceptance of GOCOVRI by physicians, hospital administrators, patients, third-party payers, and others in the healthcare community;
coverage and adequate reimbursement of GOCOVRI by third-party payers;
willingness and ability of patients to pay out of pocket for GOCOVRI;
successfully establishing and maintaining commercial manufacturing with third parties;
acceptance of GOCOVRI by the physicians, patients and the healthcare community;
the acceptance of pricing and placement of GOCOVRI on payers’ formulary tiers and the reimbursement rates established for GOCOVRI;
effectively competing with other approved or used medicines and future compounds in development;
continued demonstration of an acceptable safety profile of GOCOVRI following approval;GOCOVRI; and
obtaining, maintaining, enforcing, and defending intellectual property rights and claims.
If we doare not achievesuccessful in addressing these issues, or one or more of these factors in a timely manner or at all,negatively affect us, we could experience significant delays or an inability to successfullyfurther commercialize GOCOVRI, which would materially harm our business.
GOCOVRI may fail to achieve the degree of market acceptance by physicians, patients, healthcare payers, and others in the medical community necessary for commercial success, negatively impacting our business.
GOCOVRI may fail to gain sufficient market acceptance by physicians, hospital administrators, patients, healthcare payers, and others in the healthcare community. The degree of market acceptance of GOCOVRI will depend on a number of factors, including:

the prevalence and severity of any side effects;
efficacy, duration of response, and potential advantages compared to alternative treatments;
the price;
the willingness of physicians to change their current treatment practices;
convenience and ease of administration compared to alternative treatments;
the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;
the effectiveness of marketing, promotion, selling, and distribution support; and
the availability of third-party insurance coverage or reimbursement.
The failure of GOCOVRI to achieve market acceptance would negatively impact our business.
We currently have only limitedcommercial experience andcapabilities with limited sales personnel. If we are unable to obtain or further developcommercial capabilities, includingrecruit and retain qualified personnel and third-party distributors, our business will be substantially harmed.
Competition for biotechnology and pharmaceutical employees, sales marketingpersonnel and market accessother key personnel we will not be successful in commercializing GOCOVRI.
is intense. We have only a limited commercial infrastructureexperienced and have limited experiencemay in the commercialization, sale, marketing, or distribution of pharmaceutical products, like GOCOVRI. To achieve commercial success of GOCOVRI, we must either develop a commercial organization, including sales, marketingfuture experience difficulty attracting and market access personnel or outsource these functionsretaining qualified candidates to third parties.fill open positions and may be required to expend significant financial resources in our employee recruitment and retention efforts. We expect that the primary focus of our commercialization efforts will be in the United States. We intend to commercialize GOCOVRI through our own sales force personnel with support from a contract sales organization (“CSO”) in certain functions. Commercialization of GOCOVRI (and other future product candidates) outside of the United States, to the extent pursued, is likely to require collaboration with one or more third parties.
There are risks involved with both establishing our own commercial capabilities and relying on third parties to perform these services. For example, recruiting and building a marketing organization and/or field sales representatives are expensive and time-consuming, and if GOCOVRI is not commercially successful, our investment would be lost if we cannot retain or reposition our sales and marketing personnel.
If we are unable to effectively build, train and equip our sales force, our ability to successfully commercialize GOCOVRI will be harmed.
GOCOVRI will be a newly marketed drug and, therefore, none of the members of our sales force has ever promoted GOCOVRI prior to its launch. In addition, GOCOVRI is the first and only drug approved by the FDA for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications. As a result, we will be required to expend significant time and resources to train our sales forcemarket, sell, and distribute GOCOVRI to beneurologists and movement disorder specialists in a credible, persuasive, and compliant manner consistent with applicable laws in marketing GOCOVRI to neurologists, movement disorder specialists, and pharmacists. In addition, we must train our sales force to ensure that we deliver a consistent and appropriate message about GOCOVRI to our customers. Iflaws. Our business could be harmed if we are unable to effectivelyrecruit, employ, appropriately train, and retain experienced sales professionals to successfully execute our sales forcecommercialization strategies and equip them with effective materials,tactics, including medical and sales literature to help them inform and educateeducating potential customers about the benefits and risks of GOCOVRI and its proper administration,administration.
Moreover, there is no guarantee that the strategies, tactics and marketing messages, or the distribution and reimbursement capabilities that we have established will be successful. Specifically, for distribution of GOCOVRI, we are heavily dependent on third-party logistics, pharmacy and distribution partners. If they are unable to perform effectively, including due to the impact of the COVID-19 pandemic on their operations, or if they do not provide efficient distribution of the medicine to patients, our efforts to successfully commercialize GOCOVRI could be put in jeopardy, which would negatively impact our ability to generate product revenues.business will suffer.
Failure to successfully obtain coverage and reimbursement for GOCOVRI or if coverage and reimbursement is only available at limited levels in the United States, willor the availability of coverage and reimbursement only at limited levels, would diminish our ability to generate product revenue.
Our ability to commercialize GOCOVRI or any products successfully in the United States will depend in part on the extent to which we obtain and maintain coverage and reimbursement for these products becomes availableGOCOVRI from third-party payers, including government health administration authorities, such as those that administer the Medicare and Medicaid programs, and private health insurers. Patients who are prescribed medicine for the treatment of their conditions generally rely on third-party payers to reimburse all or part of the costs associated with their prescription drugs. Coverage and adequate reimbursement from both governmental healthcare programs, such as Medicare and Medicaid, and

commercial payers isare critical to new product acceptance.GOCOVRI’s commercial success. Coverage and reimbursement decisions may depend upon clinical and economic standards that disfavor newnewer drug products when more established or lower costcheaper therapeutic alternatives are already available or subsequently become available. CoverageFor example, even though other versions of amantadine are not approved for dyskinesia, some payers have asked physicians if patients have had prior experience with such versions or required that physicians actually prescribe such versions prior to providing reimbursement for GOCOVRI.
For some patients, coverage and reimbursement may not be available for products that we commercialize and, if reimbursement is available, we cannot guarantee what the level of reimbursement will be. Coverage and reimbursement may impact the demand for, or the price of, any product for which we obtain marketing approval.
There may be significant delays in obtaining coverage and reimbursement for approved products, and coverage may be more limited than the purposes for which the product is approved by the FDA. Moreover, eligibility for reimbursement does not imply that any product will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, distribution, marketing, and sale. Interim payments for new products, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Payment rates may vary according to the use of the product, the clinical setting in which it is used, and generic competitor availability, and may be based on initial payments for generic competitors or payments allowed for lower cost products that are already reimbursed and may be incorporated into existing payments for other services. Net prices for products may be reduced by mandatory discounts or rebates required by government healthcare programs, e.g., the federal 340B Drug Pricing Program, or private third-party payers and by any future relaxation of laws that currently restrict imports of products from countries where they may be sold at lower prices than in the United States. In the United States, private third-party payers often rely upon Medicare coverage and reimbursement policies and payment limitations in setting their own coverage and reimbursement policies. Our inability to promptly obtain coverage, reimbursement, and profitable payment rates from both government funded and private third-party payers for new products that we develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products, and our overall financial condition.
Also, evenGOCOVRI. Even if we obtain coverage for GOCOVRI, the resulting reimbursement payment rates might not be adequate or may require co-payments or co-insurance payments that patients find unacceptably high. Coverage and reimbursement determinations by third-party payers can impact the demand for GOCOVRI and therefore our revenues. Patients may choose not to use GOCOVRI if coverage is not provided or reimbursement is inadequate to cover a significant portion of its cost. If coverage and reimbursement isare not available or isare available only to limited levels, we may notour business could be ableharmed.

Our inability to successfully commercialize GOCOVRI.obtain and maintain coverage and adequate reimbursement rates from both government-funded and private third-party payers for GOCOVRI could have a material adverse effect on our operating results, and our overall financial condition.
We face substantial competition which may result in others discovering, developing, or commercializing products before or more successfully than we do.the commercialization of GOCOVRI.
The development and commercialization of new pharmaceutical products is highly competitive. Wecompetitive, and we face substantial competition with respect to our current product and product candidates, including GOCOVRI, and will face competition with respect to any future products that we may seek to develop or commercialize from major pharmaceutical companies, specialty pharmaceutical companies, and biotechnology companies worldwide.GOCOVRI. For example, although GOCOVRI is the first and only FDA-approved medicine for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications, maywe face competition from various branded and generic drugs approved for the treatment of Parkinson’s disease though not dyskinesia, such as Azilect (Teva Pharmaceuticals Industries, Ltd.), Requip XL (GlaxoSmithKline plc), Mirapex ER (Boehringer Ingelheim Pharmaceuticals Inc.), Neupro Patch (UCB SA/NV), Sinemet (Merck & Co., Inc.), Parcopa (Jazz Pharmaceuticals, Inc.), Rytary (Impax), Duopa (AbbVie), Xadago (safinamide) (Newron Pharmaceuticals S.p.A.)that physicians either have historically used or may use in attempt to manage dyskinesia. If approved, we will also face competition from investigational drugs in late stage development for the treatment of Parkinson’s disease, and immediate release amantadine. GOCOVRI may also face competition from drugs currently in development for dyskinesia in Parkinson’s disease or for Parkinson’s disease from a number of pharmaceutical companies, such as Merck, Novartis, Osmotica Pharmaceuticals Corp., Avanir Pharmaceuticals, Neurolixis, Amarantus BioScience, Addex Pharma, and Neurim Pharmaceuticals Ltd. Other products in late stage development for Parkinson’s disease includes product candidates from Kyowa Hakko, Acorda, Neuroderm, Bial-Portela CSA, Genervon Biopharmaceuticals, Pharma Two B, and Depomed.companies.
Many of our competitors, including a number of large pharmaceutical companies that compete directly with us, have significantly greater financial resources and expertise in research and development, manufacturing, conducting clinical trials, obtaining regulatory approvals, and commercializing approved products than we do. These third parties will compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical study sites, and patient registration for clinical studies, as well as in acquiring technologies and products complementary to, or necessary for, our programs. Finally,Also, many of our competitors are large pharmaceutical companies that will have a greater ability to reduce prices for their competing drugs in an effort to gain market share and undermine the value proposition that we might otherwise be able to offer to payers.

GOCOVRI will face competition from generic versions of immediate release amantadine and potentially from other extended release versions of amantadine that may be in development. For example, while immediate release amantadine is not approved for use in Parkinson’s disease for the treatment of dyskinesia, some physicians may still prescribe it for such conditions. In addition, a competitor has registered two Phase 3 clinical trials of extended release amantadine for dyskinesia on clinicaltrials.gov.
If we are unable to maintain orphan exclusivity for GOCOVRI for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications, our business would be substantially harmed.
Under the Orphan Drug Act, the FDA may designate a drug product as an orphan drug if it is a drug or biologic intended to treat a rare disease or condition. Generally, if a drug product with an orphan drug designation receives the first marketing approval for the indication for which it has such designation, the drug product is entitled to a period of marketing exclusivity, which may preclude the FDA from approving another marketing application for the same drug product for the same therapeutic indication. The applicable period of exclusivity is up to seven (7) years in the United States. GOCOVRI received orphan designation for the treatment of levodopa-induced dyskinesia in 2015. When it was approved for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications, GOCOVRI earned 7-years of orphan drug exclusivity. The FDA has recognized GOCOVRI’s orphan drug exclusivity by letter to us and on its Orphan Drug Designation and Approvals database listing.
Although we have obtained marketing approval for GOCOVRI for the treatment of dyskinesia, the FDA could still subsequently approve the same drug with the same active moiety for the same condition, if the FDA concludes that the later drug is safer, more effective, or makes a major contribution to patient care. If we are unable to maintain orphan drug exclusivity for GOCOVRI for the treatment of dyskinesia, our business would be substantially harmed.
There is an ongoing open label safety study with GOCOVRI in Parkinson’s disease patients with dyskinesia; therefore, there could be new safety findings regarding GOCOVRI.
There is an ongoing safety study with GOCOVRI. If any new safety concerns emerge from our ongoing clinical study, we may:
have the product removed from the market;
be subject to additional post-marketing testing requirements; or
be subject to restrictions on how the product is distributed, marketed, or used.
Any of these unforeseen events could impair our ability to commercialize GOCOVRI and harm our business and results of operations.
Unforeseen safety issues could emerge with GOCOVRI that could require us to change the prescribing information to add warnings, limit use of the product, and/or result in litigation. Any of these events could have a negative impact on our business.
Discovery of unforeseen safety problems or increased focus on a known problem could impact our ability to commercialize GOCOVRI and could result in restrictions on its permissible uses, including withdrawal of the medicine from the market.
If we or others identify additional undesirable side effects caused by GOCOVRI after approval:
regulatory authorities may require the addition of labeling statements, specific warnings, contraindications, or field alerts to physicians and pharmacies;
regulatory authorities may withdraw their approval of the product and require us to take our approved drugs off the market;
we may be required to change the way the product is administered, conduct additional clinical trials, change the labeling of the product, or implement a Risk Evaluation and Mitigation Strategy, (REMS);or REMS;

we may have limitations on how we promote our drugs;
third-party payers may limit coverage or reimbursement for GOCOVRI;
sales of GOCOVRI may decrease significantly;
we may be subject to litigation or product liability claims; and
our reputation may suffer.
Any of these events could prevent us from achieving or maintaining market acceptance of the affected productGOCOVRI and could substantially increase our commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenue from its sale.
Further, GOCOVRI may also be affected by the safety and tolerability of its parent drug or drugs with similar mechanisms of action. Although amantadine, which is a component of GOCOVRI, has been used in patients for many years, newly observed toxicitiesproblems identified with other approved amantadine products or worsening of known toxicities in preclinical studies or in subjectsamantadine products being studied in clinical studies receiving amantadine, or reconsideration of known toxicities of compounds in the setting of new indications,trials could result in increased regulatory scrutiny of our products and product candidates.
In addition, problems with approved products marketed by third parties that utilize the same therapeutic target and/or that belong to the same therapeutic class as amantadine could adversely affect the commercialization of GOCOVRI. 
If a safety issue emerges post-approval, we may become subject to costly product liability litigation by our customers, their patients or their patients.payers. Product liability claims could divert management’s attention from our core business,
30

be expensive to defend, and result in sizable damage awards against us that may not be covered by insurance. If we cannot successfully defend ourselves against claims that our product candidates or productsGOCOVRI caused injuries, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:
decreased demand for any product candidates or products that we may develop;
the inability to commercialize any products that we may develop;
injury to our reputation and significant negative media attention;
withdrawal of patients from clinical studies or cancellation of studies;
significant costs to defend the related litigation;
substantial monetary awards to patients; and
loss of revenue.
We currently hold $10.0$15.0 million in product liability insurance coverage, which may not be adequate to cover all liabilities that we may incur. Insurance coverage is increasingly expensive. We may not be able to obtain insurance coverage at a reasonable cost or in amounts adequate to satisfy any liability or associated costs that may arise in the future. These events could harm our business and results of operations and cause our stock price to decline. 
If manufacturers obtain approval for generic versions of GOCOVRI, or of products with which we compete, our business may suffer.
Under the U.S. Food, Drug and Cosmetic Act, or FDCA, the FDA can approve an Abbreviated New Drug Application, or ANDA, for a generic version of a branded drug without the ANDA applicant undertaking the clinical testing necessary to obtain approval to market a new drug. Generally, in place of such clinical studies, an ANDA applicant usually needs only to submit data demonstrating that its product has the same active ingredient(s), strength, dosage form, route of administration and that it is bioequivalent to the branded product. We will face riskshave recently settled an ANDA litigation with a generic filer. See Litigation and Other Legal Proceedings in “Note 7 – Commitments and Contingencies” in the developmentaccompanying “Notes to Condensed Consolidated Financial Statements (unaudited)” for more information. However, other filers could submit an ANDA to the FDA requesting permission to manufacture and market another generic version of ADS-5102 (GOCOVRI) for additional indicationsGOCOVRI, which could result in our expending significant time and other product candidates.
There are risks associated with pursuing clinical trialsincurring significant expenses in other indications for ADS-5102 (GOCOVRI), as we may experience numerous unforeseen events during,challenging the submissions.Further, if one or asmore of these filers is successful, the introduction of a resultgeneric version of clinical studies thatGOCOVRI could harm our ability to commercialize or to receive regulatory approval for other indications of ADS-5102, including that:
clinical studies may produce negative or inconclusive results or raise significant safety concerns,business and we may decide, or regulators may require us, to conduct additional clinical studies or abandon product development programs;
even if clinical studies demonstrate statistically significant efficacy and acceptable safety, the FDA or similar authorities outside the United States may not consider the results of our studies to be sufficient for approval;

our clinical sites and clinical investigators may fail to comply with, or inconsistently apply, the trial protocols, regulatory requirements including Good Clinical Practices, contractual obligations, and the rating assessments;
our third-party vendors, including our Contract Research Organizations (“CROs”) may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;
we might have to suspend or terminate clinical studies for various reasons, including a finding that our product candidates have unanticipated serious side effects or other unexpected characteristics or that the patients are being exposed to unacceptable health risks;
regulators or institutional review boards may require that we or our investigators suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements; and
the supply or quality of ADS-5102 or other materials necessary to conduct clinical studies may be insufficient or inadequate.
Although the safety profile of amantadine, the active pharmaceutical ingredient in GOCOVRI, is already characterized in the approved label for amantadine (i.e., Symmetrel®) and in the GOCOVRI clinical trial data in the dyskinesia population, there can be no assurance that our clinical development program for ADS-5102 (GOCOVRI) for multiple sclerosis walking impairment or future studies in other indications, will not reveal additional safety or tolerability issues. In such an event, our ability to commercialize GOCOVRI for dyskinesia and/or expand our business could be compromised.
If we are forced to delay or abandon development of our product candidates, our business, results of operations and financial condition will be materially and adversely harmed.cause our stock price to decline.
The marketing and promotion of GOCOVRI willmust be limited to the approved indication for use and the information and clinical data included in or consistent with the approved prescribing information. If we want to expand the marketing and promotion of GOCOVRI beyond the approved indication or with information not consistent with the approved prescribing information, we will need to obtain additional regulatory approvals, which may not be granted.
With the August 24, 2017 approval of GOCOVRI (formerly ADS-5102) for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications, we will becurrently are permitted to market or promote it, consistent with the information and data in its approved prescribing information, only for the treatment of dyskinesia and not for other uses. We are developing ADS-5102, the formulation in GOCOVRI for at least one additional indication, treatment of walking impairment in patients with multiple sclerosis, and potentially others. In order tosclerosis.To market and promote GOCOVRI for thesethis additional indications,indication, we willmay need to conduct an additional clinical trialstrial to obtain regulatory approval for such use that will likely be time-consuming and expensive, and to obtain regulatory approval for such uses. Additionally, ourexpensive. Our current marketing and promotional efforts will beis limited to the use of information included in or deemed to be consistent with the approved prescribing information for GOCOVRI for the treatment of dyskinesia, including the clinical data and results reflected in the prescribing information. To use information not consistent with the approved prescribing information will require additional regulatory approvals.
If we are found to have improperly promoted unapproved uses of our products,GOCOVRI, or if physicians misuse our products,it, we may be subject to restrictions on the sale or marketing of our products,GOCOVRI and significant fines, penalties, sanctions and sanctions, product liability claims, and our image and reputation within the industry and marketplace could be harmed.
The FDA and other regulatory agencies, including regulatory authorities outside the United States, strictly regulate the marketing and promotional claims that are made about drug products, such as GOCOVRI. In particular, promotion forof a product must be consistent with its labeling approved by the FDA or by regulatory agencies in other countries. For example, in the case of GOCOVRI, for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications, we cannot prevent physicians from prescribing GOCOVRI for indications or uses that are inconsistent with the approved label. If, however, we are found to have promoted such unapproved uses prior to the FDA’s approval for an additional indication, we may, among other consequences, receive untitled or warning letters and become subject to significant liability, which would materially harm our business. Both the U.S. federal government and foreign regulatory authorities have levied significant civil and criminal fines against companies and individuals for alleged improper promotion and have entered into settlement agreements with pharmaceutical companies to limit inappropriate promotional activities. If we become the

target of such an investigation or prosecution based on our marketing and promotional practices, we could face similar
31

sanctions, which would materially harm our business. In addition, management’s attention could be diverted from our business operations, significant legal expenses could be incurred, and our reputation could be damaged.
Physicians’Physicians prescribing of our products for unapproved uses may also subject us to product liability claims, to the extent such uses lead to adverse events, side effects, or injury. Product liability claims could divert management’s attention from our core business, be expensive to defend, and result in sizable damage awards against us that may not be covered by insurance. Furthermore, the use of our products for indications other than those approved by the FDA or regulatory authorities outside the United States may not effectively treat such conditions, which could harm our reputation in the marketplace among physicians and patients. Any of these events could harm our business and results of operations and cause our stock price to decline.
If we fail to comply with our reporting and payment obligations under the Medicaid Drug Rebate Program or other governmental pricing programs in the United States, we could be subject to additional reimbursement requirements, fines, sanctions and exposure under other laws which could have a material adverse effect on our business, results of operations and financial condition.
We will participate in the Medicaid Drug Rebate Program, as administered by the Centers for Medicare and Medicaid Services, or CMS, and other federal and state government pricing programs in the United States, and we may participate in additional government pricing programs in the future. These programs generally require us to pay rebates or otherwise provide discounts to government payers in connection with drugs that are dispensed to beneficiaries/recipients of these programs. In some cases, such as with the Medicaid Drug Rebate Program, the rebates are based on pricing that we report on a monthly and quarterly basis to the government agencies that administer the programs. Pricing requirements and rebate/discount calculations are complex, vary among products and programs, and are often subject to interpretation by governmental or regulatory agencies and the courts. The requirements of these programs, including, by way of example, their respective terms and scope, change frequently. Responding to current and future changes may increase our costs, and the complexity of compliance will be time consuming. Invoicing for rebates is provided in arrears, and there is frequently a time lag of up to several months between the sales to which rebate notices relate and our receipt of those notices, which further complicates our ability to accurately estimate and accrue for rebates related to the Medicaid program as implemented by individual states. Thus, there can be no assurance that we will be able to identify all factors that may cause our discount and rebate payment obligations to vary from period to period, and our actual results may differ significantly from our estimated allowances for discounts and rebates. Changes in estimates and assumptions may have a material adverse effect on our business, results of operations and financial condition.
In addition, the Office of Inspector General of the Department of Health and Human Services and other Congressional enforcement and administrative bodies have recently increased their focus on pricing requirements for products, including, but not limited to the methodologies used by manufacturers to calculate average manufacturer price, or AMP, and best price, or BP, for compliance with reporting requirements under the Medicaid Drug Rebate Program. We are liable for errors associated with our submission of pricing data and for any overcharging of government payers. For example, failure to submit monthly/quarterly AMP and BP data on a timely basis could result in asignificant civil monetary penalty of $10,000 per daypenalties for each day the submission is late beyond the due date. Failure to make necessary disclosures and/or to identify overpayments could result in allegations against us under the Federal False Claims Act and other laws and regulations. Any required refunds to the U.S. government or responding to a government investigation or enforcement action would be expensive and time consuming and could have a material adverse effect on our business, results of operations and financial condition. In addition, in the event that the CMS were to terminate our rebate agreement, no federal payments would be available under Medicaid or Medicare for our covered outpatient drugs.
GOCOVRI is complex to manufacture, and manufacturing disruptions may occur that could cause us to experience disruptions in the supply of GOCOVRI or our product candidates.GOCOVRI.
GOCOVRI is ana high-dose, extended release versionamantadine taken once-daily at bedtime that delivers high levels of amantadine.amantadine in the morning upon waking and throughout the day. The manufacture of extended release versions of drugs is more complex than the manufacture of the immediate release versions of drugs. Notwithstanding the fact that we have validated our process, manufacturing disruptions may occur.occur, including disruptions related to the impact or uncertainties of the duration of the COVID-19 pandemic. Such problems may prevent the production of lots that meet the specifications required for sale of the product and may be difficult and expensive to resolve. Although we have an adequate supply of GOCOVRI to address patient needs into late 2021 and have not observed disruptions in our supply chain to date as a result of COVID-19, there is no guarantee that will we not experience interruption of, or delays in receiving, supply due to staffing shortages, production slowdowns or stoppages and disruptions in delivery systems in the future. If any such issues were to arise with respect to GOCOVRI, or our future product candidates, our business, financial results, or stock price could be adversely affected.

Our success depends on the timely development, approval and successful commercialization of our product candidates. If we are unable to do anymaintain orphan exclusivity for GOCOVRI for the treatment of thesedyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications, our product candidatesbusiness may be substantially harmed.
When GOCOVRI was approved for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications, GOCOVRI earned seven years of orphan drug exclusivity under the Orphan Drug Act. Even so, the FDA could still subsequently approve the same drug with the same active moiety for the same indication if the FDA concludes that the later drug is safer or more effective or

If we are unable to maintain orphan drug exclusivity for GOCOVRI for the treatment of dyskinesia, our business willwould be materiallysubstantially harmed.
We have invested a significant portion of our efforts and financial resources into the
Risks related to ADS-5102 in clinical development and potential commercialization ofany other product candidates
Our ability to benefit from our product candidates, includinginvestment in ADS-5102 for the treatment of walking impairment in patients with multiple sclerosis depends on the timely clinical development, approval and potentially other indications, as well as ADS-4101successful commercialization of ADS-5102 for this indication.
We have invested significant effort and financial resources into the development and potential commercialization of ADS-5102 for the treatment of partial onset seizureswalking impairment in epilepsy.patients with multiple sclerosis. Our ability to generate product revenue from this product in development will depend heavily on the successful development, regulatory approval, and commercialization of our other product candidates.ADS-5102 for this indication. The success of our product candidatesADS-5102 for the treatment of walking impairment in patients with multiple sclerosis will depend on numerous factors, including:
successfully engaging with the FDA and developing a regulatory pathway for ADS-5102 based on data from the INROADS trial;
successfully completing the development program for our product candidates in a timely manner;manner, especially in light of the COVID-19 pandemic;
receiving marketing approval for our product candidates from the FDA in a timely manner;manner, especially in light of the COVID-19 pandemic;
successfully establishing and maintaining commercial manufacturing with third parties;
commercializing our product candidates,products, if approved, including marketing, sales, and distribution of the product independently or in partnership with another company;
acceptance by the medical community and patients of the approved product;
the pricingcoverage and placementadequate reimbursement by third-party payers;
willingness and ability of our product candidates on payers’ formulary tiers and the reimbursement rates establishedpatients to pay out of pocket for the approved products;
effectively competing with other approved or used medicines and future compounds in development;
continued demonstration of an acceptable safety profile of the approved products following approval; and
obtaining, maintaining, enforcing, and defending intellectual property rights and claims.
If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize our product candidates,ADS-5102 for the treatment of walking impairment in patients with multiple sclerosis, which would materiallycause us not to realize on our investment in ADS-5102 for this indication. In addition, if we determine to pursue development of ADS-5102 for additional indications other than for the treatment of walking impairment in patients with multiple sclerosis, we will face many of these factors for those additional indications.
We will face risks in the development of ADS-5102 for additional indications.
There are risks associated with pursuing clinical trials in other indications for ADS-5102, including for the treatment of walking impairment in patients with multiple sclerosis, as we may experience numerous unforeseen events during, or as a result, of clinical studies that could harm our business.ability to commercialize such products or to receive regulatory approval, including that:
clinical studies may produce negative or inconclusive results or raise significant safety concerns, and we may decide, or regulators may require us, to conduct additional clinical studies or abandon product development programs;
even if clinical studies demonstrate statistically significant efficacy and acceptable safety, the FDA or similar authorities outside the United States may not consider the results of our studies to be sufficient for approval;

our clinical sites and clinical investigators may fail to comply with, or inconsistently apply, the trial protocols, regulatory requirements including Good Clinical Practices, contractual obligations, and the rating assessments;
our third-party vendors, including our Contract Research Organizations, or CROs, and contract manufacturing organizations, or CMOs, may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;
we might have to suspend or terminate clinical studies for various reasons, including a finding that our products have unanticipated serious side effects or other unexpected characteristics or that the patients are being exposed to unacceptable health risks;
regulators or institutional review boards may require that we or our investigators suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements;
the supply or quality of ADS-5102 or other materials necessary to conduct clinical studies may be insufficient or inadequate; and
our new product discovery or research program may not be successful or warrant clinical development.
If we are forced to delay or abandon development of our products, our business, results of operations, and financial condition will be materially and adversely harmed.
We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidatesproducts or indications that may be more profitable or for which there is a greater likelihood of success.
Because we have limited financial and managerial resources, we have chosen to focus on research programs and product candidatesproducts for specific indications. As a result, we may forego or delay pursuit of opportunities with otherour product candidatescandidate or other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our investment in current and future research and development programs and product candidates for specific indications may not yield any commercially viable products.products for us or future partners.
If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing, or other royalty arrangements in cases in which it would have been advantageous for us to retain sole development and commercialization rights.
If manufacturers obtainFailure to gain approval for generic versions of or successfully commercialize ADS-5102 in additional indications in the United States could substantially harm our business.
We will face the same or similar challenges in obtaining FDA approval and in commercialization and manufacturing ADS-5102 as GOCOVRI, or of products with which we compete, our business may suffer.
Under the U.S. Food, Drug and Cosmetic Act, or FDCA, the FDA can approve an Abbreviated New Drug Application, or ANDA, for a generic version of a branded drug without the ANDA applicant undertaking the clinical testing necessary to obtain approvalas outlined above, including but not limited to market a new drug. Generally, in place of such clinical studies, an ANDA applicant usually needs only to submit data demonstrating that its product has the same active ingredient(s), strength, dosage form, route of administrationacceptance by physicians and that it is bioequivalent to the branded product.
The FDCA requires that an applicant for approval of a generic form of a branded drug certify either that its generic product does not infringe any of the patents listedpatients, coverage and reimbursement by the owner of the branded drug in the Approved Drug Products with Therapeutic Equivalence Evaluations, also known as the Orange Book, or that those patents are not

enforceable. This process is known as a paragraph IV challenge. Upon receipt of the paragraph IV notice, the owner has 45 days to bring a patent infringement suit in federal district court against the company seeking ANDA approval of a product covered by one of the owner’s patents. The discovery, trial,third party payers, and appeals process in such suits can take several years. If this type of suit is commenced, the FDCA provides a 30-month stay on the FDA’s approval of the competitor’s application. This type of litigation is often time-consuming and costly and may result in generic competition if the patents at issue are not upheld or if the generic competitor is found not to infringe the owner’s patents. Such litigation has been commenced by Forest Laboratories Holdings Limited (“Forest”), an indirect wholly-owned subsidiary of Allergan plc (collectively, “Allergan”) and us to enforce certain patents related to Namenda XR® and Namzaric®. See Litigation in “Note 7 - Commitments and Contingencies” in the accompanying “Notes to Condensed Consolidated Financial Statements (unaudited)” for more information. manufacturing issues.
If the litigation is resolved in favorwe resume development of the ANDA applicantADS-4101, or the challenged patent expires during the 30-month stay period, the stay is lifted and the FDA may thereafter approve the application based on the standards for approval of ANDAs. Once an ANDA is approved by the FDA, the generic manufacturer may market and sell the generic form of the branded drug in competition with the branded medicine.
Risks related to our financial condition and need for additional capital
If we donot have adequate funds to cover all of our development and commercial activities, we may have toraise additional capital orcurtail or cease operations.
We expect to begin to launch GOCOVRI for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications, in 2018, and it will require substantial funds to be successful. In addition, funds are required for the continued operation of our business, as we seek to advancedevelop additional product candidates through the research and clinical development to regulatory approval and commercialization. On May 11, 2017, we entered into a Sales Agreement with Cowen and Company, LLC under whichthat we may offer and sell our common stock having aggregate sales proceeds of up to $50 million from time to time through Cowen and Company, LLC as our sales agent. As of September 30, 2017,develop or acquire, we have not made any sales under this facility. As of September 30, 2017, we had approximately $130.7 million in cash, cash equivalents, and investments. We believe that our available cash, cash equivalents, and investments will be sufficient to fund our anticipated level of operations for at leastface the next 12 months, but there can be no assurance that this will be the case.
We have financed our operations primarily through proceeds from our license agreement with Allergan, public and private equity offerings, and, to a lesser extent, our Royalty-Backed Loan with HCRP, government grants, venture debt, and benefits from tax credits made available under a federal stimulus program supporting drug development. We have devoted substantially all of our efforts to researchsame regulatory and development including clinical studies, of our product candidates, including GOCOVRI forrisks that we face with the treatment of dyskinesia in patients with Parkinson’s disease. We anticipate that our cash requirements will increase substantially as we:
enhance operational, financial, and information management systems and hire more personnel, including personnel to support development of our product candidates and, our commercial operations;
commercialize GOCOVRI, including establishing distribution, marketing, and sales capabilities;
manufacture GOCOVRI for commercial use;
investigate ADS-5102 (GOCOVRI) in preclinical and clinical trials for the treatment of walking impairment in patients with MS, and potentially other indications;multiple sclerosis.
conduct preclinical and clinical trials ofAlthough we have placed the development program for ADS-4101 (lacosamide) modified release capsules for the treatment of partial onset seizures in patients with epilepsy (partial onset seizures);
seek regulatory approvals for ouron hold, if we determine to resume development of ADS-4101, or develop or acquire other potential product candidates that successfully complete clinical studies;
continue the research, development, and manufacture of our current product candidates; and
seek to discover or in-license additional product candidates.
Ifdevelop them, we do not have adequate funds to support these activities, our business opportunities could be hindered. 

If we need additional funds to operate our business andif we cannot raise additional capital when needed, or if additional capital is not available to us on favorable terms, our stockholders may be adversely affected or our business may be harmed.
If we need additional funds to support our business and additional funding is not available under our Royalty-Backed Loan with HCRP, or from new funding sources on favorable terms or at all, we may need to delay or reducewill face the scope of our research and clinical development programs or commercialization efforts. We do not have any committed external source of funds or other support for our development efforts other than under our Royalty-Backed Loan with HCRP, or from new funding sources or under our license agreement with Allergan, which may be terminated by Allergan upon delivery of notice. We expect to finance future cash needs through a combination of public or private equity offerings, debt financings, royalty financings, collaborations, strategic alliances, licensing arrangements, asset sales,same regulatory and other marketing and distribution arrangements. Additional financing may not be available to us whendevelopment risks that we need it or it may not be available on favorable terms. If we raise additional capital through debt financings, royalty financings, collaborations, strategic alliances, or licensing arrangementsface with third parties, we may have to relinquish certain valuable rights to our product candidates, technologies, future revenue streams, or research programs or grant licenses on terms that may not be favorable to us. If we raise additional capital through equity offerings, the ownership interestdevelopment of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, in addition to the repayment of principal and interest on negotiated terms, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the scope of, or suspend one or more of our clinical studies or research and development programs or our commercialization efforts. 
We have outstanding debt backed by two of our principal assets, GOCOVRI and royalties we may receive on Namzaric, and failure by us or our royalty subsidiary to fulfill our obligations under the applicable loan agreements may cause the repayment obligations to accelerate.
In May 2017, we, through a newly formed wholly-owned subsidiary, entered into a royalty-backed note arrangement with HealthCare Royalty Partners III, L.P. (“HCRP”) pursuant to which we initially borrowed $35 million and will borrow an additional $65 million upon FDA approval and FDA’s recognition in the Orange Book of the 7-year orphan drug exclusivity that GOCOVRI earned upon approval on August 24, 2017,ADS-5102 for the treatment of dyskinesiawalking impairment in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications. The FDA has already recognized GOCOVRI’s orphan drug exclusivity by letter to us and on its Orphan Drug Designation and Approvals database listing.multiple sclerosis discussed above.
Interest and principal on the loan will be payable from the proceeds of royalty on U.S. net sales of GOCOVRI and up to $15 million of our annual royalties from Allergan on U.S. net sales of Namzaric® starting in May 2020. The HCRP notes mature in December 2026, if not earlier prepaid.
We secured the loan with rights to GOCOVRI (ADS-5102) and rights to certain payment amounts on Namzaric and the loan documents further provide for assignment into our subsidiary holding these rights to any future intellectual property, licenses, assets and agreements with respect to the manufacture, development, supply, distribution, sale and commercialization of GOCOVRI. The loan documents contain customary events of default permitting HCRP to accelerate and require mandatory prepayment of outstanding principal and interest, including: failure to timely pay principal and interest when due and payable; failure to perform specified covenants with respect to maintenance of the collateral and prohibitions on liens with respect to the collateral; limitations on payments of dividends, additional loans, acquisition or merger transactions not in accordance with the arrangement. Upon the occurrence, an event of default under the loan documents, we could be required to prepay the entire loan and, if we are not able to do so, we may lose control over certain rights and payments to GOCOVRI and royalty payments with respect to Namzaric, either of which would seriously harm our business.
Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations.
Our quarterly and annual operating results may fluctuate significantly in the future which makes it difficult for usseek to predict our future operating results. Any future revenue will depend on the successful commercialization and sales of GOCOVRI and our product candidates, the payment of royalties to us from Allergan under terms of our licensing agreement regarding Namenda XR® and Namzaric®, or the establishment of potential future collaboration and license

agreements, if any, and the achievement of any upfront or milestone payments provided thereunder. Furthermore, our operating results may fluctuate due to a variety of other factors, many of which are outside of our control and may be difficult to predict, including: 
the level of demand for our products, which may vary significantly as they are launched and compete for position in the marketplace;
pricing and reimbursement policies with respect to GOCOVRI and product candidates, if approved, and the competitive response from existing and potential future therapeutic approaches that compete with our product candidates;
the cost of manufacturing ouracquire additional product candidates, which may vary duesubject us to a numberadditional risks and expense.
In the future in seeking to diversify our product candidate portfolio we may seek to identify and acquire or in-license novel product candidates. We may fail to identify and acquire or in-license product candidates, including for reasons discussed in these risk factors, and also:
34

the termsprocess by which we identify and decide to acquire product candidates may not be successful;
the competition to acquire or in-license promising product candidates is fierce and many of our agreementscompetitors are large, multinational pharmaceutical, biotechnology and medical device companies with contract manufacturing organizations, or CMOs;considerably more financial, development and commercialization resources and experience than we have;
the timing, cost, level of investment, and success or failure of research and development activities relating to our preclinical and clinical-stagepotential product candidates which may, change from timeupon further study during or after the acquisition process, fail to time;demonstrate clinical efficacy, be shown to have harmful side effects or other characteristics that indicate that they are unlikely to be products that will receive marketing approval or achieve market acceptance; and
expenditures thatpotential product candidates may not be effective in treating their targeted diseases.
In addition, if we may incur todo acquire and develop additional product candidates and technologies;
the timingthey prove to be unsuccessful, we will have spent significant amounts of resources in acquiring and success or failure of clinical studies for competingpursuing these product candidates, orand not receive any other change in the competitive landscape of our industry, including consolidation among our competitors or partners;
the timing and magnitude of upfront and milestone payments under any potential future collaboration and licensing agreements;
future accounting pronouncements or changes in our accounting policies; and
changing or volatile U.S., European, and global economic environments.
The cumulative effects of these factors could result in large fluctuations and unpredictability in our quarterly and annual operating results. As a result, comparing our operating results on a period-to-period basis may not be meaningful. Investors should not relyreturn on our past results as an indication ofinvestments. Further, time and resources spent searching for, identifying, acquiring, and developing potential product candidates may distract management’s attention from our future performance. This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our operating results fall below the expectations of analysts or investors or below any forecasts we may provide to the market, or if the forecasts we provide to the market are below the expectations of analysts or investors, the price of our common stock could decline substantially. Such a stock price decline could occur even when we have met any previously publicly stated operating results and/or earnings guidance that we may provide.existing business.
Risks related to our reliance on third parties
We rely on third-party contract manufacturing organizations to manufacture, serializesupply, and supplydistribute GOCOVRI and our product candidates.ADS-5102. If one of our suppliers or manufacturersthese organizations fails to perform adequately or fulfill our needs, we may be required to incur significant costs and devote significant efforts to find new suppliers third party vendors and/or manufacturers and qualify them. We may also face delays in the development, commercialization and supply of GOCOVRI or our product candidates.ADS-5102.
We currently have limited experience in, and we do not own facilities for clinical and commercial manufacturing of GOCOVRI or our product candidates,ADS-5102, and we rely upon third-party contract manufacturing organizations to manufacture, serialize and supply drug product for our clinical studies and to meet potential commercial demand. The manufacture of pharmaceutical products in compliance with the FDA’s current Good Manufacturing Practices, or cGMPs, requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. Manufacturers of pharmaceutical products oftenIf our manufacturers were to encounter difficulties in production, including difficulties with production costs and yields, quality control, including stability of the product candidateGOCOVRI or ADS-5102 and quality assurance testing, shortages of qualified personnel, as well as complianceespecially in light of the COVID-19 pandemic, or fail to comply with strictly enforced cGMP requirements, other federal and state regulatory requirements, and foreign regulations. If our manufacturers were to encounter any of these difficulties or otherwise fail to comply with their obligations to us or under applicable regulations, our commercial supply of GOCOVRI or product candidatesADS-5102 in our clinical trials could be jeopardized. We have little control over our manufacturers’ operations or their compliance with applicable regulations and standards. Any delay or interruption in the supply of clinical study materials or commercial product could cause delays in our clinical

programs, harm our ability to gain approval from regulatory authorities, and potentially disrupt patient access to our approved products. These events would substantially harm our business, reputation and stock price.
We also rely on a single specialty pharmacy to distribute and provide access to GOCOVRI for the vast majority of our patients. Accordingly, this specialty pharmacy is the Company’s largest customer representing approximately 98% of the Company’s product revenue. If this specialty pharmacy fails to perform, it could materially harm our business.
All third-party manufacturers of our products product candidates and ingredients thereof must comply with cGMP requirements enforced by the FDA through its facilities inspection program. These requirements include, among other things, quality control, quality assurance, and the maintenance of records and documentation. Manufacturers of our products and product candidates may be unable to comply with these cGMP requirements and with other FDA, state and foreign regulatory requirements. The FDA or similar foreign regulatory agencies may also implement new standards at any time, or change their interpretation and enforcement of existing standards for manufacture, packaging, or testing of products. We have little control over our manufacturers’ compliance with these regulations and standards. A failure to comply with these requirements may result in fines and civil penalties, suspension of production, suspension or delay in product approval, product seizure or recall, or withdrawal of product approval. If the safety of any product supplied is compromised due to our manufacturers’ failure to adhere to applicable laws or for other reasons, we may not be able to obtain regulatory approval for or successfully commercialize our products or product candidates and we may be held liable for any injuries sustained as a result. Any of these factors could cause a delay of clinical studies, regulatory submissions, approvals, commercialization or supply of our products, or product candidates, entail higher costs, impair our reputation, and potentially disrupt patient access or our approved products.
35

We rely on a single source third-party contract manufacturing organization for the manufacture and supply ofour drug substances and drug product for GOCOVRI and our other product candidates.ADS-5102.
WeAlthough we have supply agreements with two drug substance suppliers, only one is currently manufacturing at commercial scales required for GOCOVRI. In addition, we also currently rely on a single source suppliers for our drug substancesproduct manufacturer for GOCOVRI and our other product candidates.ADS-5102. We continue to seek additional long-term supply agreements with suppliers and supplier qualifications. A failure of our single source manufacturer or drug substance supplier or our failure to qualify at least one other manufacturer organization on a timely basis, especially in light of the current COVID-19 pandemic, and validate the manufacturing process employed at that manufacturer or supplier could delay or harm commercialization of GOCOVRI or our product candidates.ADS-5102. Although we believe alternative sources of supply exist, the number of third-party suppliers with the necessary manufacturing and regulatory expertise and facilities is limited, and it could be expensive and take a significant amount of time to arrange and negotiate acceptable long-term contracts and obtain regulatory approvals and qualifications, which would adversely affect our business. New suppliers of any product candidatedrug substance would be required to be qualified under applicable regulatory requirements including demonstration of bioequivalence of the product made at the new supplier, and would need to have sufficient rights under applicable intellectual property laws to the method of manufacturing the product candidate.product. Obtaining the necessary FDA approvals or other qualifications under applicable regulatory requirements and ensuring non-infringement of third-party intellectual property rights could result in a significant interruption of supply and could require the new manufacturer to bear significant additional costs, which may be passed on to us. Qualifying and negotiating long-term contracts with manufacturers and providers of packaging services is a lengthy process. If at any time, one or more of our qualified contract manufacturing organizations were not able to manufacture our drug substance or drug product or provide the requisite services, our business and financial condition would be materially adversely affected.
In our existing or any future potential collaborations or partnerships, we will likely not be able to control all aspects of the development andcommercialization ofour products or product candidates. This lack ofcontrolcould subject us to additional risks that could harm our business.
Collaborations or license agreements involving our current or future products are subject to numerous risks, which may include that:
partners have significant discretion in determining the efforts and resources that they will apply to collaborations;
partners may not pursue development and commercialization of our product candidates or may elect not to continue or renew development or commercialization programs based on clinical study results, changes in their strategic focus due to the acquisition of competitive products, availability of funding, or other external factors, such as a business combination that diverts resources or creates competing priorities;
partners may delay clinical studies, provide insufficient funding for a clinical study program, stop a clinical study, abandon a product candidate, repeat or conduct new clinical studies, or require a new formulation of a product candidate for clinical testing;

partners could independently develop, or develop with third parties, products that compete directly or indirectly with our products or product candidates;
a partner with marketing, manufacturing, and distribution rights to one or more products may not commit sufficient resources to or otherwise not perform satisfactorily in carrying out these activities;
we could grant exclusive rights to our partners that would prevent us from collaborating with others;
Allergan and future partners may not properly maintain or defend our intellectual property rights or may use our intellectual property or proprietary information in a way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential liability;
Allergan and future partners may not aggressively or adequately pursue litigation against ANDA filers or may settle such litigation on unfavorable terms, and as Allergan substantially controls the current ANDA litigation and terms of settlement and has different economic interests than ours, Allergan may grant licenses to generic manufacturers that permit them to make and sell generic versions of Namenda XR® and Namzaric®, which would negatively impact the royalties we receive under our license with Allergan;
disputes may arise between us and a partner that causes the delay or termination of the research, development, or commercialization of our current or future products or that results in costly litigation or arbitration that diverts management attention and resources;
agreements may be terminated, sometimes at-will, without penalty, and, if terminated, may result in a need for additional capital to pursue further development or commercialization of the applicable current or future products;
partners may own or co-own intellectual property covering our products that results from our collaborating with them, and in such cases, we would not have the exclusive right to commercialize such intellectual property; and
a partner’s sales and marketing activities or other operations may not be in compliance with applicable laws resulting in civil or criminal proceedings.
We rely on third parties to conduct our clinical trials, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of these trials.
We do not independently conduct clinical studies of our product candidates.products. Instead, we rely on third parties, such as CROs, clinical data management organizations, medical institutions, and clinical investigators to perform this function. Our reliance on these third parties for clinical development activities reduces our control over these activities, but does not relieve us of our responsibilities. For example, the FDA requires us to comply with standards, commonly referred to as Good Clinical Practice, for conducting, recording, and reporting the results of clinical studies to assure that data and reported results are credible and accurate and that the rights, integrity, and confidentiality of patients in clinical studies are protected, even though we are not in control of these processes. These third parties may also have relationships with other entities, some of which may be our competitors. If these third parties do not successfully carry out their contractual duties, meet expected deadlines, or conduct our clinical studies in accordance with regulatory requirements or our stated protocols, we will not be able to obtain, or may be delayed in obtaining, regulatory approvals for our product candidatesproducts and will not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates.products.
We also rely on other third parties to store and distribute supplies for our clinical studies. Any performance failure on the part of our existing or future distributors could delay clinical development or regulatory approval of our product candidatesproducts or commercialization of our products, producing additional losses and depriving us of potential product revenue.

Risks related to Namenda XR® and Namzaric®
Under our license agreement with Allergan, if Allergan fails to successfully commercialize Namenda XR® and Namzaric® for any reason or if the license agreement with Allergan is terminated, the potential royalties we are eligible to receive under our license agreement with Allergan may not occur or be minimal, and would have a negative impact on our revenue potential and harm our business. 
In November 2012, we entered into a license agreement with Allergan pursuant to which we granted Allergan a right to develop and commercialize Namenda XR® and Namzaric® in the United States. Under that agreement, we expect to receive future royalties from Allergan on the net sales of Namenda XR® and Namzaric®, starting in 2018 and 2020, respectively. If Allergan fails to successfully commercialize Namenda XR® and, more importantly, Namzaric®, on which we are eligible to receive double digits percentage royalties for any reason, we may not receive such future royalties or receive minimal amounts, and our business will be harmed.
Under the license agreement, we are reliant on Allergan to commercialize Namenda XR® and Namzaric® and in that capacity Allergan has the discretion to: 
determine the efforts and resources that they apply towards commercialization;
market, manufacture, and distribute the licensed products or to otherwise not perform satisfactorily in carrying out these activities; and
to terminate the agreement without penalty and, such termination, may result in a need for additional capital to pursue further development or commercialization of the applicable current or future products. 
Under the license agreement, Allergansubstantially controls the intellectual property rights subject to the agreementandthe current ANDA litigation andpotentialsettlement thereof, and has economic interests different from ours. Accordingly,Allergan may manage the litigation and settlements on terms which may have a material and negative impact on our business. 
We and Allergan are currently involved in ANDA litigation to enforce our intellectual property rights against generic manufacturers, who are seeking to bring generic versions of Namenda XR® and Namzaric® to the market. See Litigation in “Note 7 - Commitments and Contingencies” in the accompanying “Notes to Condensed Consolidated Financial Statements (unaudited)”. Under the terms of that license agreement, Allergan has the right to enforce such intellectual property rights and control such litigation. Specifically, Allergan has the discretion to: 
maintain or defend our intellectual property rights or may use our intellectual property or proprietary information in a way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential liability; and
not adequately pursue litigation against ANDA filers or settle such litigation on unfavorable terms, and as Allergan substantially controls the current ANDA litigation and terms of settlement and has different economic interests than ours, Allergan may grant licenses to generic manufacturers that permit them to make and sell generic versions of Namenda XR® and Namzaric®, which would negatively impact the royalties we receive under our license with Allergan.
We have a right to participate in, but not control, such litigations. If Allergan decides not to enforce the intellectual property rights licensed under the agreement or the litigation is resolved in favor of the generic manufacturers or if the FDA approves the ANDA filed by the generic manufacturers, such manufacturers may be able to market and sell the generic form of the branded drug in competition with Namenda XR® and Namzaric®. This could harm our business.
The post-marketing safety risks relating to Namzaric® and Namenda XR® are the same as those facing GOCOVRI.
The post-marketing safety risks relating to Namzaric® and Namenda XR® are the same as those facing GOCOVRI, which are described in the risk factor captioned “Unforeseen safety issues could emerge with GOCOVRI that could require us to change the prescribing information to add warnings, limit use of the product, and/or result in litigation. Any of these events could have a negative impact on our business.” These things could lead us to experience

failure to receive regulatory approval or receive approval with unexpected safety information in the prescribing information that could limit physician and patient acceptance of the product.
Risks related to government regulation
TheChanges in healthcare law and implementing regulations, including government restrictions on pricing and reimbursement, as well as healthcare policy and other healthcare payer cost-containment initiatives and current societal pressures regarding pharmaceutical product pricing, may negatively impact our ability to generate revenues from or could limit or prevent our products’ commercial success.
In the United States, there have been and we expect there will continue to be a number of legislative and regulatory approval process is expensive, time consuming,changes to the healthcare system that could affect our future revenue and uncertainprofitability and may prevent us or our collaboration partners from obtaining approvals for the commercialization of some or allfuture revenue and profitability of our product candidates.potential customers. Federal and state lawmakers regularly propose and, at times, enact legislation that would result in significant changes to the healthcare system, some of which are intended to contain or reduce the costs of medical products and services. For example, in March 2010, the Patient Protection and Affordable Care Act (“PPACA”) was passed, which has substantially changed how healthcare is financed by both governmental and private insurers, and has significantly impacted the U.S. pharmaceutical industry. Details of healthcare regulations,
36

including changes under the PPACA, are discussed in the business heading “Other healthcare regulations” in Part I, Item 1, of our 2019 Annual Report on Form 10-K.
We expect that the PPACA, as currently enacted or as it may be amended in the future, and other healthcare reform measures that may be adopted in the future, could have a material adverse effect on our industry generally and on our ability to maintain or increase sales of our existing products.
The research, development, manufacturing, quality control, labeling, approval, safety, effectiveness, storage, record keeping, reporting, selling, import, export, advertising, promotion, marketing,continuing efforts of the government, insurance companies, managed care organizations, other payers of healthcare services, and distributionpatient and political groups to contain or reduce costs of drughealthcare may, among other things, adversely affect:
our ability to set a price we believe is fair for our products;
the reputation of our company;
our ability to generate revenue and achieve or maintain profitability; and
the availability of capital.
Our ability to commercialize our products are subjectsuccessfully, and to extensive regulation byattract commercialization partners for our products, will depend in significant part on the FDAavailability of adequate financial coverage and other regulatory authoritiesreimbursement from third-party payers, including, in the United States, governmental payers such as the Medicare and by regulatory authorities in other countries, with different regulations from country to country. Neither we nor our collaboration partnersMedicaid programs, managed care organizations and private health insurers. Details of these considerations are permitted to market our product candidatesdiscussed in the United States or other countries until we receive FDA approval of an NDA. On August 24, 2017, GOCOVRI was FDA-approved for the treatment of dyskinesiabusiness heading “Other healthcare regulations” in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications. The FDA will need to approve supplemental NDAs for GOCOVRI before we can market the drug for other indications, such as multiple sclerosis walking impairment.
To receive approval to commercialize anyPart I, Item 1, of our product candidates in the United States, we and our collaboration partners must demonstrate with substantial evidence from adequate and well-controlled clinical studies, and to the satisfaction of the FDA, that such product candidates2019 Annual Report on Form 10-K.
We are safe and effective for their intended uses. Results from preclinical studies and clinical studies can be interpreted in different ways. Even if we and our collaboration partners believe the preclinical or clinical data for our product candidates are promising, such data may not be sufficient to support approval by the FDA. Administering any of our product candidates to humans may produce undesirable side effects, which could interrupt, delay, or cause suspension of clinical studies of our product candidates and result in the denial of approval of our product candidates for any or all targeted indications.
FDA approval of an NDA is not guaranteed, and the approval process is expensive and may take several years. The FDA also has substantial discretion in the approval process. Despite the time and expense we invest, failure can occur at any stage, and we could encounter problems that require us to repeat clinical studies, perform additional preclinical studies and clinical studies, or abandon development and commercialization of a product candidate altogether. The number of preclinical studies and clinical studies that will be required for FDA approval varies depending on, among other factors, the product candidate, the disease or condition that the product candidate is designed to address, and the regulations applicable to any particular product candidate. The FDA can delay, limit, or deny approval of a product candidate for many reasons, including, but not limited to:
disagreement with the design or implementation of our clinical trials;
failure of clinical trials to show the level of statistical significance or clinical meaningfulness needed for approval;
failure to demonstrate that a product candidate is safe or effective;
insufficient data from preclinical and clinical studies to support an application;
a finding by an institutional review board (IRB), Data Safety Monitoring Board (DSMB), Data Monitoring Committee (DMC), or the FDA that the clinical trial exposes subjects or patients to an unacceptable health risk;
disapproval of our or our third-party manufacturer’s processes or facilities; or
changes to FDA’s approval policies or regulations.
If any of our product candidates fails to demonstrate safety and efficacy in clinical studies or does not gain regulatory approval, our business and results of operations will be materially and adversely harmed.

If the FDA concludes that our product candidates do not satisfy the requirements for approval under the Section 505(b)(2) regulatory approval pathway, or if the requirements for approval under Section 505(b)(2) are not as we expect, the approval pathway for our products will likely take significantly longer, cost significantly more, and entail significantly greater complications and risks than anticipated, and in any case may not be successful.Similar obstacles may arise in other countries.
Similar to the approval pathway for GOCOVRI, we are developing our current and future product candidates, with the expectation that they will be eligible for approval through the Section 505(b)(2) regulatory pathway. Section 505(b)(2) of the FDCA allows an NDA to rely in part on the FDA’s prior conclusions regarding the safety and effectiveness of an approved drug product, or reference listed drug (RLD). Use of the Section 505(b)(2) regulatory pathway could reduce the time required for the development programs of our product candidates by, for example, potentially decreasing the amount of preclinical and/or clinical data specific to a product candidate that we would need to generate in order to obtain FDA approval. If the FDA does not allow us to pursue the Section 505(b)(2) regulatory pathway as anticipated, we may need to conduct additional clinical trials, provide additional data and information, and meet additional standards for product approval. If this were to occur, the time and financial resources required to obtain FDA approval for our product candidates, and the complications and risks associated with regulatory approval would likely substantially increase. Moreover, our inability to pursue the Section 505(b)(2) regulatory pathway may result in competitive products reaching the market more quickly than our product candidates, which would adversely impact our competitive position and prospects. Even if we are able to utilize the Section 505(b)(2) regulatory pathway, there is no guarantee that utilizing this pathway will ultimately lead to faster product development or earlier approval for any product candidate that we may attempt to develop and commercialize.
An NDA submitted through the Section 505(b)(2) regulatory pathway for a drug product with an active moiety that has been previously approved in another product (e.g., amantadine) may be entitled to three years of regulatory exclusivity if the NDA contains data from clinical investigations (other than bioavailability or bioequivalence studies) conducted by or for the sponsor and deemed essential to FDA’s approval of the NDA. This regulatory exclusivity precludes, among other things, approval of another 505(b)(2) NDA for a product with the same conditions of approval. Although obtaining such exclusivity for our product candidates could provide a competitive benefit for us, the availability of such exclusivity to competitors, if their products were to be approved before our product candidates, presents a risk. If a competing product were approved in our target indication and granted three years of exclusivity, and if the FDA were to find that our product candidate does not differ with respect to the relevant conditions of approval of the approved competing product, then approval of the 505(b)(2) NDA for our product candidate in the target indication may be delayed for as long as the competitor has exclusivity. 
With a Section 505(b)(2) NDA, we also must certify to the FDA concerning any patents listed for the RLD in the Orange Book. A certification that our product candidate does not infringe the RLD’s Orange Book-listed patents, or that such patents are invalid (known as a paragraph iv certification) would require providing notice of that certification to the patent holder and the sponsor of the RLD NDA, and we could then be challenged in court by the patent owner or the holder of the approved NDA for the RLD. If such a lawsuit were to be filed within a specified timeframe, it would lead to a 30-month period during which FDA would be precluded from approving our NDA.
With the approval of GOCOVRI, we will continue to be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and subject us to penalties if we fail to comply with applicable regulatory requirements.
With the approval of GOCOVRI, theThe manufacturing, marketing, and further development of the approved productGOCOVRI are subject to continual review by the FDA and/or analogous non-U.S. regulatory authorities. Any regulatory approval that we or our collaboration partners receive for our product candidates will be subject to limitations on the indicated uses for which the product may be marketed, and may be subject to requirements for potentially costly post-marketing follow-up studies to monitor the safety and efficacy of the product. In addition, if the FDA and/or analogous non-U.S. regulatory authorities approve any of our product candidates, we are and will be subject to extensive and ongoing regulatory requirements with regard to the labeling, packaging, adverse event reporting, storage, distribution, advertising, promotion, tracking, recordkeeping, and periodic reporting for our products. Further, we and our contract manufacturers of our drug products are required to comply with cGMP regulations, which include requirements related to quality control and quality assurance and maintenance of records and documentation. Regulatory authorities must approve manufacturing facilities before they can be used to manufacture our drug products, and these facilities are subject to continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP

regulations. Certain changes to the manufacturing processes for our product candidates, if approved, would also be subject to pre-approval by regulatory authorities. In addition, if we or a third party discover previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured, a regulatory authority may impose restrictions on that product, its manufacturer, or us, including but not limited to requiring withdrawal of the product from the market or suspension of manufacturing. If we, our product candidatesproducts or the manufacturing facilities for our product candidatesproducts fail to comply with regulatory requirements of the FDA and/or applicable non-U.S. regulatory authorities, we could be subject to administrative or other sanctions, including:
warning letters or untitled letters;
civil or criminal penalties and fines;
injunctions;
suspension, variation, or withdrawal of regulatory approval;
suspension of ongoing clinical studies;
voluntary or mandatory product recalls;
requirements for dissemination of corrective information or modifications to promotional materials;
refusal to approve pending applications for marketing approval of new drugs or supplements to approved applications filed by us;
refusal to permit import or export of our products;
37

restrictions on operations, including costly new manufacturing requirements; or
seizure or detention of our products.
Regulatory requirements and policies may change, and we may need to comply with additional laws and regulations that are enacted. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or in other countries. If we are not able to maintain regulatory compliance, we may not be permitted to market, or continue to market, our future products and our business may suffer.
ChangesIf we fail to comply with healthcare regulations, we could face substantial penalties and our business, operations, and financial condition could be adversely affected.
Healthcare providers, physicians, distributors, and third-party payers play a primary role in the distribution, recommendation, and prescription of any pharmaceutical product for which we obtain marketing approval. Our arrangements with third-party payers and customers expose us to broadly applicable federal and state fraud and abuse and other laws and regulations that may constrain the business or financial arrangements through which we market, sell and distribute GOCOVRI and other products for which we may obtain marketing approval. The laws and regulations that may affect our ability to operate include: the federal healthcare lawprogram Anti-Kickback Statute, the federal civil and criminal false claims laws, including the federal civil False Claims Act and civil monetary penalties laws, the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, including as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their implementing regulations, the federal Physician Payments Sunshine Act, being implemented as the Open Payments Program, and analogous state laws and regulations, such as anti-kickback, and false claims laws, which may be broader in scope and apply to items or services reimbursed by any third-party payer, including government restrictions oncommercial insurers.
If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including significant civil, criminal and/or administrative penalties, damages, fines, disgorgement, possible exclusion from participation in Medicare, Medicaid, and other federal healthcare programs, imprisonment, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, reputational harm, diminished profits and future earnings, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results. Any action against us for violation of these or other laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. Moreover, achieving and sustaining compliance with applicable federal and state privacy, security, and fraud laws may prove costly. In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. Moreover, the requirements governing drug pricing and reimbursement vary widely from country to country.
Health Technology Assessment, or HTA, of medicinal products is becoming an increasingly common part of the pricing and reimbursement procedures, and most European Union member states now have an HTA system. The HTA process in the European Union member states is governed by the national laws of these countries. HTA is the procedure according to which the assessment of the public health impact, therapeutic impact and the economic and societal impact of the use of a given medicinal product in the national healthcare systems of the individual country is conducted. HTA generally focuses on the clinical efficacy and effectiveness, safety, cost, and cost-effectiveness of individual medicinal products as well as their potential implications for the national healthcare policysystem. Those elements of medicinal products are compared with other treatment options available on the market.
The outcome of HTA may influence the pricing and other healthcare payer cost-containment initiativesreimbursement status for specific medicinal products within individual European Union member states. The extent to which pricing and current societal pressures regarding pharmaceuticalreimbursement decisions are influenced by the HTA of a specific medicinal product pricing, may negatively impact our ability to generate revenues from or could limit or prevent our product candidates’ commercial success.vary between the European Union member states.
In 2011, Directive 2011/24/EU was adopted at European Union level. This Directive concerns the United States, there have beenapplication of patients’ rights in cross-border healthcare. The Directive is intended to establish rules for facilitating access to safe and we expect there will continuehigh-quality cross-border healthcare in the European Union. Pursuant to beDirective 2011/24/EU, a numbervoluntary network of legislativenational authorities or bodies responsible for HTA in the individual EU member states was established. The purpose of the network is to facilitate and regulatory changes tosupport the healthcare system that could affect our future revenue and profitabilitycooperation between national authorities or bodies and the future revenue and profitabilityexchange of our potential customers. Federal and state lawmakers regularly propose and, at times, enact legislation that would result in significant changes

information concerning HTAs. This could lead to greater harmonization between European Union member states of the healthcare system, some of which are intended to contain or reduce the costs of medical products and services. For example, in March 2010, the PPACA was passed, which has substantially changed how healthcare is financed by both governmental and private insurers, and has significantly impacted the U.S. pharmaceutical industry. Details of changes under the PPACA are discussedcriteria taken into account in the business heading “Other healthcare regulations”conduct of HTA in Part I, Item 1, of our 2016 Annual Report on Form 10-K.
Legislative and regulatory changes to the PPACA remain possible and appear likely in the 115th United States Congress and under the Trump Administration. We expect that the PPACA, as currently enacted or as it may be amended in the future, and other healthcare reform measures that may be adopted in the future, could have a material adverse effect on our industry generally and on our ability to maintain or increase sales of our existing products. There have also been proposals to impose federal rebates on Medicare Part D drugs, requiring federally-mandated rebates on all drugs dispensed to Medicare Part D enrollees or on only those drugs dispensed to certain groups of lower income beneficiaries.

If any of these proposals are adopted, they could result in our owing additional rebates, which could have a negative impact on revenues from sales of our products.
The continuing efforts of the government, insurance companies, managed care organizations, other payers of healthcare services, and patient and political groups to contain or reduce costs of healthcare may, among other things, adversely affect:
our ability to set a price we believe is fair for our products;
the reputation of our company;
our ability to generate revenue and achieve or maintain profitability; and
the availability of capital.
Our ability to commercialize our products successfully, and to attract commercialization partners for our products, will depend in significant part on the availability of adequate financial coveragepricing and reimbursement from third party payers, including, in the U.S., governmental payers such as the Medicare and Medicaid programs, managed care organizations and private health insurers. Details of these considerations are discussed in the business heading “Other healthcare regulations” in Part I, Item 1, of our 2016 Annual Report on Form 10-K.decisions.
If we fail to comply with our reporting and payment obligations under the Medicaid Drug Rebate program or other governmental pricing programs that we may join if we successfully commercialize any of our product candidates, we could be subject to additional reimbursement requirements, penalties, sanctions and fines, which could have a material adverse effect on our business, financial condition, results of operations and growth prospects.
We intend to participate in and then will have certain price reporting obligations to the Medicaid Drug Rebate program and other governmental pricing programs.
Under the Medicaid Drug Rebate program, a manufacturer is required to pay a rebate to each state Medicaid program for its covered outpatient drugs that are dispensed to Medicaid beneficiaries and paid for by a state Medicaid program as a condition of having federal funds being made available to the states for our drugs under Medicaid and Medicare Part B. Those rebates are based on pricing data reported by the manufacturer on a monthly and quarterly basis to the Centers for Medicare and Medicaid Services, or CMS, the federal agency that administers the Medicaid Drug Rebate program. These data include the average manufacturer price and, in the case of innovator products, the best price for each drug which, in general, represents the lowest price available from the manufacturer to any entity in the United States in any pricing structure, calculated to include all sales and associated rebates, discounts and other price concessions.
The PPACA made significant changes to the Medicaid Drug Rebate program, as discussed under the heading “Other healthcare regulations” in Part I, Item 1, of our 20162019 Annual Report on Form 10-K. On February 1, 2016, CMS issued final regulations to implement the changes to the Medicaid Drug Rebate program under the PPACA. These regulations became effective on April 1, 2016. The issuance of regulations and coverage expansion by various governmental agencies relating to the Medicaid Drug Rebate program may increase our costs and the complexity of compliance and could have a material adverse effect on our results of operations if we participate in the Medicaid Drug Rebate Program if and when we successfully commercialize any of our product candidates.
Federal law requires that any company that participates in the Medicaid Drug Rebate program also participate in the Public Health Service’s 340B drug pricing program in order for federal funds to be available for the manufacturer’s drugs under Medicaid and Medicare Part B. The 340B program requires participating manufacturers to agree to charge no more than the 340B “ceiling price” for the manufacturer’s covered outpatient drugs to a variety of community health clinics and other entities that receive health services grants from the Public Health Service, as well as hospitals that serve a disproportionate share of low-income patients. The PPACA expanded the list of covered entities to include certain free-standing cancer hospitals, critical access hospitals, rural referral centers and sole community hospitals, but exempts “orphan drugs” from the ceiling price requirements for these covered entities. The 340B ceiling price is calculated using a statutory formula based on the average manufacturer price and rebate amount for the covered outpatient drug as calculated under the Medicaid Drug Rebate program. Changes to the definition of average manufacturer price and the Medicaid rebate amount under the Healthcare Reform Act and CMS’s final regulations implementing those changes also

could affect the 340B ceiling price calculations for any of our product candidates that we successfully commercialize and could negatively impact our results of operations.
The PPACA obligates the Secretary of the HHS to update the agreement that manufacturers must sign to participate in the 340B program to obligate a manufacturer to offer the 340B price to covered entities if the manufacturer makes the drug available to any other purchaser at any price and to report to the government the ceiling prices for its drugs. The Health Resources and Services Administration, or HRSA, recently initiated the process of updating the agreement with participating manufacturers. The PPACA also obligates the Secretary of the HHS to create regulations and processes to improve the integrity of the 340B program. In 2015, HRSA issued proposed omnibus guidance that addresses many aspects of the 340B program, and in August 2016, HRSA issued a proposed regulation regarding an administrative dispute resolution process for the 340B program. It is unclear when or whether the guidance or regulation will be released in final form underAfter implementation delays directed by the Trump Administration. On January 5, 2017,Administration, on November 30, 2018, HRSA issued apublished its final regulationrule regarding the calculation of 340B ceiling price and the imposition of civil monetary penalties on manufacturers thatfor knowingly and intentionally overchargeovercharging covered entities.entities, which became effective on January 1, 2019. The March 6, 2017 effective date of this regulation is subject to a temporary delay directed by the Trump Administration, and the regulation could be subject to further delay or other modification by the Trump Administration. Implementation of this final rule and the issuance of any other final regulations and guidance could affect our obligations under the 340B program in ways we cannot anticipate, if and when we successfully commercialize any of our product candidates and if we participate in the 340B program. In addition, legislation may be introduced that, if passed, would further expand the 340B program to additional covered entities or would require participating manufacturers to agree to provide 340B discounted pricing on drugs used in an inpatient setting.

Pricing and rebate calculations vary across products and programs, are complex, and are often subject to interpretation by the reporting manufacturer, governmental or regulatory agencies and the courts. In the case of Medicaid pricing data, if we join the Medicaid Drug Rebate Program and become aware that our reporting for a prior quarter was incorrect, or has changed as a result of recalculation of the pricing data, we will be obligated to resubmit the corrected data for up to three years after those data originally were due. Such restatements and recalculations would increase our costs for complying with the laws and regulations governing the Medicaid Drug Rebate program and could result in an overage or underage in our rebate liability for past quarters. Price recalculations also may affect the ceiling price at which we would be required to offer any of our product candidates that we successfully commercialize under the 340B drug discount program.
We will be liable for errors associated with any submission of pricing data. In addition to retroactive rebates and the potential for 340B program refunds, if we are found to have knowingly submitted any false price information to the government, we may be liable for significant civil monetary penalties in the amount of $178,156 per item of false information. Our failure to submit the required price data on a timely basis could result in asignificant civil monetary penalty of $17,816 per daypenalties for each day the information is late beyond the due date. Such failure also could be grounds for CMS to terminate our Medicaid drug rebate agreement, pursuant to which we will participate in the Medicaid program if we join the program if and when we successfully commercialize any of our product candidates. In the event that CMS terminates our rebate agreement, federal payments may not be available under Medicaid or Medicare Part B for any of our product candidates that we successfully commercialize.
CMS and the OIG have pursued manufacturers that were alleged to have failed to report these data to the government in a timely manner. Governmental agencies may also make changes in program interpretations, requirements or conditions of participation, some of which may have implications for amounts previously estimated or paid. We cannot assure you that our submissions, if we participate in the federal programs if and when we successfully commercialize any of our product candidates, will not be found by CMS to be incomplete or incorrect.
In order to be eligible to have any of our product candidates that we successfully commercialize paid for with federal funds under the Medicaid and Medicare Part B programs and purchased by the Department of Veterans Affairs, (“VA”),or VA, Department of Defense, Public Health Service, and Coast Guard, (the “Bigreferred to collectively as the Big Four agencies”),agencies, and certain federal grantees, we are required to participate in the VA Federal Supply Schedule, (“FSS”)or FSS, pricing program, established under Section 603 of the Veterans Health Care Act of 1992. Under this program, we are obligated to make any of our product candidates that we successfully commercialize that meet the statutory definition of “covered drug” (biologics and single and innovator multiple source drugs) available for procurement on an FSS contract and charge a price to the Big Four agencies that is no higher than the Federal Ceiling Price, (“FCP”),or FCP, which is a price calculated pursuant to a statutory formula. The FCP is derived from a calculated price point called the “non-federal average manufacturer price” (“Non-

FAMP”),price,” or Non-FAMP, which we will be required to calculate and report to the VA on a quarterly and annual basis. Pursuant to applicable law, knowing provision of false information in connection with a Non-FAMP filing can subject a manufacturer to significant penalties of $178,156 for each item of false information. The FSS contract also contains extensive disclosure and certification requirements.
Under Section 703 of the National Defense Authorization Act for FY 2008, we will be required to pay quarterly rebates on utilization of innovator products that are dispensed through the Tricare network pharmacies to Tricare beneficiaries. The rebates are calculated as the difference between the annual Non-FAMP and FCP. If we overcharge the government in connection with the FSS contract or Tricare Retail Pharmacy Rebate Program, whether due to a misstated FCP or otherwise, we are required to refund the difference to the government. Failure to make necessary disclosures and/or to identify contract overcharges can result in allegations against us under the False Claims Act and other laws and regulations. Unexpected refunds to the government, and any response to government investigation or enforcement action, would be expensive and time-consuming, and could have a material adverse effect on our business, financial condition, results of operations, and growth prospects if we successfully commercialize any of our product candidates.
If we fail to comply with healthcare regulations, we could face substantial penalties and our business, operations, and financial condition could be adversely affected.
Healthcare providers, physicians, distributors, and third-party payers play a primary role in the distribution, recommendation, and prescription of any pharmaceutical product for which we obtain marketing approval. Our arrangements with third-party payers and customers expose us to broadly applicable federal and state fraud and abuse and other laws and regulations that may constrain the business or financial arrangements through which we market, sell and distribute any products for which we have obtained or may obtain marketing approval. The laws and regulations that may affect our ability to operate include:
the federal healthcare program Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully offering, paying, soliciting, or receiving any remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, order, lease, arrangement or recommendation of, any good, facility, item, or service for which payment may be made, in whole or in part, under federal healthcare programs, such as the Medicare and Medicaid programs. Liability under the Anti-Kickback Statute may be established without a person or entity having actual knowledge of the statute or specific intent to violate it. In addition, the government may assert that a claim including items or services resulting from a violation of the Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act;
the federal civil False Claims Act, which prohibits individuals or entities from, among other things, knowingly presenting, or causing to be presented, false or fraudulent claims for payment of government funds, or knowingly using false records or statements, to obtain payment from the federal government. In recent years, several pharmaceutical and other health care companies have faced enforcement actions under the False Claims Act for, among other things, allegedly submitting false or misleading pricing information to government healthcare programs, providing free product to customers with the expectation that the customers would bill federal programs, product and patient assistance programs, including reimbursement services, and marketing products for off-label or unapproved uses;
the federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), which prohibits, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payer (e.g., public or private) and knowingly and willfully falsifying, concealing, or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment for, healthcare benefits, items, or services relating to healthcare matters. HIPAA also imposes obligations on certain entities, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information. HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 (HITECH), and their respective implementing regulations, also governs the conduct of certain electronic healthcare transactions and protects the security and privacy of protected health information;

the federal Physician Payment Sunshine Act, being implemented as the Open Payments Program, which requires manufacturers of drugs, devices, biologicals, and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program (with certain exceptions) to report annually to the federal government information related to payments and other transfers of value made to physicians (defined to include doctors, dentists, optometrists, podiatrists, and chiropractors) and teaching hospitals, as well as certain ownership and investment interests held by physicians and their immediate family members; and
analogous state laws and regulations, such as anti-kickback, and false claims laws, which may be broader in scope and apply to items or services reimbursed by any third-party payer, including commercial insurers. Several states also require pharmaceutical companies to report expenses relating to the marketing and promotion of pharmaceutical products in those states and to report gifts and payments to individual health care providers in those states. Some of these states also prohibit certain marketing-relating activities, including the provision of gifts, meals, or other items to certain health care providers. In addition, several states require pharmaceutical companies to implement compliance programs or marketing codes.
If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including civil, criminal and/or administrative penalties, damages, fines, disgorgement, possible exclusion from participation in Medicare, Medicaid, and other federal healthcare programs, reputational harm, diminished profits and future earnings, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results. Any action against us for violation of these or other laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. Moreover, achieving and sustaining compliance with applicable federal and state privacy, security, and fraud laws may prove costly.
In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. Moreover, the requirements governing drug pricing and reimbursement vary widely from country to country. For example, in the European Union the sole legal instrument at the European Union level governing the pricing and reimbursement of medicinal products is Council Directive 89/105/EEC (the Price Transparency Directive). The aim of the Price Transparency Directive is to ensure that pricing and reimbursement mechanisms established in European Union member states are transparent and objective, do not hinder the free movement and trade of medicinal products in the European Union, and do not hinder, prevent or distort competition on the market. The Price Transparency Directive does not, however, provide any guidance concerning the specific criteria on the basis of which pricing and reimbursement decisions are to be made in individual European Union member states. The national authorities of the individual European Union member states are free to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices and/or reimbursement of medicinal products for human use. Some individual European Union member states adopt policies according to which a specific price or level of reimbursement is approved for the medicinal product. Other European Union member states adopt a system of reference pricing, basing the price or reimbursement level in their territory either, on the pricing and reimbursement levels in other countries, or on the pricing and reimbursement levels of medicinal products intended for the same therapeutic indication. Furthermore, some European Union member states impose direct or indirect controls on the profitability of the company placing the medicinal product on the market.
Health Technology Assessment (HTA) of medicinal products is becoming an increasingly common part of the pricing and reimbursement procedures in some European Union member states. These countries include the United Kingdom, France, Germany, and Sweden. The HTA process in the European Union member states is governed by the national laws of these countries. HTA is the procedure according to which the assessment of the public health impact, therapeutic impact and the economic and societal impact of the use of a given medicinal product in the national healthcare systems of the individual country is conducted. HTA generally focuses on the clinical efficacy and effectiveness, safety, cost, and cost-effectiveness of individual medicinal products as well as their potential implications for the national healthcare system. Those elements of medicinal products are compared with other treatment options available on the market.
The outcome of HTA may influence the pricing and reimbursement status for specific medicinal products within individual European Union member states. The extent to which pricing and reimbursement decisions are influenced by the HTA of a specific medicinal product vary between the European Union member states.

In 2011, Directive 2011/24/EU was adopted at European Union level. This Directive concerns the application of patients’ rights in cross-border healthcare. The Directive is intended to establish rules for facilitating access to safe and high-quality cross-border healthcare in the European Union. Pursuant to Directive 2011/24/EU, a voluntary network of national authorities or bodies responsible for HTA in the individual EU member states was established. The purpose of the network is to facilitate and support the exchange of scientific information concerning HTAs. This could lead to harmonization between European Union member states of the criteria taken into account in the conduct of HTA in pricing and reimbursement decisions and negatively impact price in at least some European Union member states.
If we fail to comply with data protection laws and regulations, we could be subject to government enforcement actions (which could include civil or criminal penalties), private litigation, increased compliance costs and/or adverse publicity, which could negatively affect our operating results and business.
We are subject to data protection laws and regulations (i.e., laws and regulations that address privacy and data security). In the U.S.,United States, numerous federal and state laws and regulations, including state data breach notification laws, state health information privacy laws, and federal and state consumer protection laws (e.g., Section 5 of the FTCFederal
40

Trade Commission Act), govern the collection, use, disclosure, and protection of health-related and other personal information. Failure to comply with data protection laws and regulations could result in government enforcement actions and create liability for us, (which could includeincluding civil and/or criminal penalties),penalties, private litigation and/or adverse publicity that could negatively affect our operating results and business. In addition, we may obtain health information from third parties (e.g., healthcare providers who prescribe our products) that are subject to privacy and security requirements under HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act (the “HITECH Act”).HITECH. Although we are not directly subject to HIPAA—other than potentially with respect to providing certain employee benefits—we could be subject to criminal penalties if we knowingly obtain or disclose individually identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA. HIPAA generally requires that healthcare providers and other covered entities obtain written authorizations from patients prior to disclosing protected health information of the patient (unless an exception to the authorization requirement applies). If authorization is required and the patient fails to execute an authorization or the authorization fails to contain all required provisions, then we may not be allowed access to and use of the patient’s information and our research efforts could be delayed. Furthermore, use of protected health information that is provided to us pursuant to a valid patient authorization is subject to the limits set forth in the authorization (e.g., for use in research and in submissions to regulatory authorities for product approvals). In addition, HIPAA does not replace federal, state, international or other laws that may grant individuals even greater privacy protections.
EU member statesOn June 28, 2018, California enacted the California Consumer Privacy Act (CCPA), which took effect on January 1, 2020. The CCPA gives California residents expanded rights to access and other jurisdictions where we operatedelete their personal information, opt out of certain personal information sharing, and receive detailed information about how their personal information is used. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. The CCPA may increase our compliance costs and potential liability. Some observers have adopted data protection lawsnoted that the CCPA could mark the beginning of a trend toward more stringent state privacy legislation in the U.S., which could increase our potential liability and regulations, which impose significant compliance obligations. For example,adversely affect our business.
In the EU, Data Protection Directive imposes strict obligations and restrictions on the ability to collect, analyze and transfer personal data, including health data from clinical trials and adverse event reporting. Switzerland has adopted similar restrictions. Data protection authorities from the different EU member states may interpret the applicable laws differently, and guidance on implementation and compliance practices are often updated or otherwise revised, which adds to the complexity of processing personal data in the EU. Although there are legal mechanisms to allow for the transfer of personal data from the EU to the U.S., the decision of the European Court of Justice in the Schrems case (Case C-362/14 Maximillian Schrems v. Data Protection Commissioner) invalidated the Safe Harbor framework and increased uncertainty around compliance with European Union restrictions on cross-border data transfers. As a result of the decision, it was no longer possible to rely on safe harbor certification as a legal basis for the transfer of personal data from the EU to entities in the U.S. On February 29, 2016, however, the European Commission announced an agreement with the United States Department of Commerce (“DOC”) to replace the invalidated Safe Harbor framework with a new EU-U.S. “Privacy Shield.” On July 12, 2016, the European Commission adopted a decision on the adequacy of the protection provided by the Privacy Shield. The Privacy Shield is intended to address the requirements set out by the European Court of Justice in its ruling by imposing more stringent obligations on companies, providing stronger monitoring and enforcement by the DOC and Federal Trade Commission, and making commitments on the part of public authorities regarding access to information. U.S. companies have been able to certify to the U.S. DOC their compliance with the privacy principles of the Privacy Shield since August 1, 2016. On September 16, 2016, the Irish privacy advocacy group Digital Rights Ireland brought an action for annulment of the European Commission decision on the adequacy of the Privacy Shield before the European Court of Justice (Case T-670/16). Case T-670/16 is still pending. If, however, the European Court of Justice invalidates the Privacy Shield, it will no longer be possible to rely on the Privacy Shield certification to support transfer of personal data from the European Union to entities in the US. Adherence to the Privacy Shield is not, however, mandatory. U.S.-based

companies are permitted to rely either on their adherence to the EU-US Privacy Shield or on the other authorized means and procedures to transfer personal data provided by the EU Data Protection Directive.
In December 2015, a proposal for an EU General Data Protection Regulation intended to replace the current EU Data Protection Directive,(GDPR) took effect on May 25, 2018, introducing sweeping new data protection requirements inthat carry potential fines of up to the EU, as well as substantial fines for breachesgreater of the data protection rules, was agreed between the European Parliament, the Council20 million Euros or 4% of the European Union, and the European Commission.annual global revenue. The EU General Data Protection Regulation entered into force on May 24, 2016 and will apply from May 25, 2018. The EU Data Protection RegulationGDPR will increase our responsibility and potential liability in relation to personal data that we process, and we will also faceexpose us to substantial potential fines for breaches of the data protection rules. We may be required to put in place additional mechanisms ensuring compliance with the new EU data protection rules. Furthermore, there is a growth towards the public disclosure of clinical trial data in the European Union which adds to the complexityevent of processing health data from clinical trials.violations, increase our compliance costs and could restrict our operations in Europe.
If we or our vendors fail to comply with applicable data privacy laws, or if the legal mechanisms we or our vendors rely upon to allow for the transfer of personal data from the EU or Switzerland to the U.S. (or other countries not considered by the European Commission to provide an adequate level of data protection) are not considered adequate, we could be subject to government enforcement actionsThe regulatory approval process is expensive, time consuming, and significant penalties against us,uncertain and our business could be adversely impacted if our ability to transfer personal data outside of the European Union or Switzerland is restricted.
Failure to obtain regulatory approvals in foreign jurisdictions willmay prevent us from obtaining approvals for the commercialization of some or all of our product candidates.
The research, development, manufacturing, quality control, labeling, approval, safety, effectiveness, storage, record keeping, reporting, selling, import, export, advertising, promotion, marketing, our products internationally.
We may decide to seek marketing authorizations to commercialize GOCOVRI, ADS-4101, and other future product candidates outsidedistribution of the United States. To market our future products in the European Union and many other foreign jurisdictions, we must obtain separate regulatory approvals. Specifically, in the EU, medicinal products can only be commercialized after obtaining a Marketing Authorization, or MA.
Before granting an MA, the European Medicines Agency or the competent authorities of the member states of the EU make an assessment of the risk-benefit balance of the product on the basis of a Common Technical Document including, among other information, scientific criteria concerning its quality, safety, and efficacy.
Similar to the U.S., both marketing authorization holders and manufacturers of medicinaldrug products are subject to comprehensive regulatory oversightextensive regulation by the EMAFDA and the competent authorities of the individual EU member states both before and after grant of the manufacturing and Marketing Authorizations. This includes control of compliance with cGMP rules, which govern quality control of the manufacturing process and require documentation policies and procedures. We and our third-party manufacturers are required to ensure that all of our processes, methods, and equipment are compliant with cGMP. Failure by us or by any of our third-party partners, including suppliers, manufacturers, and distributors to comply with EU laws and the related national laws of individual EU member states governing the conduct of clinical trials, manufacturing approval, marketing authorization of medicinal products, both before and after grant of marketing authorization, and marketing of such products following grant of authorization may result in administrative, civil, or criminal penalties. These penalties could include delays in or refusal to authorize the conduct of clinical trials or to grant Marketing Authorization, product withdrawals and recalls, product seizures, suspension, or variation of the marketing authorization, total or partial suspension of production, distribution, manufacturing, or clinical trials, operating restrictions, injunctions, suspension of licenses, fines, and criminal penalties.
We have had limited interactions with foreign regulatory authorities. The approval procedures vary among countries and can involve additional clinical testing, and the time required to obtain approval may differ from and be longer than that required to obtain FDA approval. Clinical studies conducted in one country may not be accepted byother regulatory authorities in other countries. Approval by the FDA does not ensure approvalUnited States, and by regulatory authorities in other countries, and approval by one or more foreign regulatory authorities doeswith different regulations from country to country. We are not ensure approval by regulatory authorities in other foreign countries or by the FDA. However, a failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory process in others. The foreign regulatory approval process may include all of the risks associated with obtaining FDA approval as well as additional, different risks.
There is no assurance that we will be ablepermitted to obtain marketing authorizations in foreign countries on a timely basis, if at all. We may not be able to file for foreign regulatory approvals, and even if we file we may not receive necessary approvals to commercializemarket our products in any market. If we are unable to obtain non-U.S. regulatory

approval to market our product candidates in other countries, we may not be able to achieve the financial results we project and our stock price could decline.
Risks related to the operation of our business
Our future success depends on our ability to retain our chief executive officer and other key executives and to attract, retain, and motivate qualified personnel.
We are highly dependent on our chief executive officer and the other members of our executive and scientific teams. Our executives may terminate their employment with us at any time. The loss of the services of any of these people could impede the achievement of our research, development, and commercialization objectives. We maintain “key person” insurance for our chief executive officer, but not for any other executives or employees. Any insurance proceeds we may receive under this “key person” insurance would not adequately compensate us for the loss of our chief executive officer’s services.
Recruiting and retaining qualified scientific, clinical, manufacturing, and commercial personnel will also be critical to our success. We may not be able to attract and retain these personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategies. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us.
We expect to expand our development and sales and marketing capabilities, and, as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.
As of September 30, 2017, we had 84 full-time equivalent employees. Over the next several years, we expect to experience significant growth in the number of our employees and the scope of our operations, particularly in sales and marketing. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational, informational, and financial systems, expand our facilities, and continue to recruit and train additional qualified personnel. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. The physical expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.
We are an “emerging growth company,” and we cannot be certain whether the reduced reporting requirements applicable to emerging growth companies will make our common stock less attractive to investors.
We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act, or the JOBS Act, which was enacted in April 2012. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We could be an emerging growth company for up to five years, although circumstances could cause us to lose that status earlier. We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of our initial public offering, (b) in which we have total annual gross revenue of at least $1.0 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may suffer or be more volatile.

Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.
Our operations could be subject to earthquakes, power shortages, telecommunications failures, floods, hurricanes, fires, extreme weather conditions, medical epidemics, and other natural or manmade disasters or business interruptions. The occurrence of any of these business disruptions could seriously harm our operations and financial condition and increase our costs and expenses. Our corporate headquarters is located in California and certain clinical sites for our product candidates, operations of our existing and future partners, and suppliers are or will be located near major earthquake faults and fire zones. The ultimate impact on us, our significant partners, suppliers, and our general infrastructure of being located near major earthquake faults and fire zones and being consolidated in certain geographical areas is unknown, but our operations and financial condition could suffer in the event of a major earthquake, fire, or other natural or manmade disaster.
Any future operations or business arrangements with entities outside the United States present risks that could materially adversely affect our business.or other countries until we receive regulatory approvals. In August 2017, GOCOVRI was FDA-approved for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications. The FDA will need to approve supplemental NDAs for GOCOVRI before we can market the drug for other indications, such as multiple sclerosis walking impairment.
If we obtainTo receive approval to commercialize any approved products or utilize CMOs outside of the United States, a variety of risks associated with international operations could materially adversely affect our business. If any product candidates that we may develop are approved for commercialization outside the United States, we will be subject to additional risks related to entering into international business relationships, including:
different regulatory requirements for drug approvals in foreign countries;
reduced protection for intellectual property rights;
unexpected changes in tariffs, trade barriers, and regulatory requirements;
economic weakness, including inflation or political instability in particular foreign economies and markets;
difficulties in assuring compliance with foreign corrupt practices laws;
compliance with tax, employment, immigration, and labor laws for employees living or traveling abroad;
foreign taxes, including withholding of payroll taxes;
foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incident to doing business in another country;
workforce uncertainty in countries where labor unrest is more common than in the United States;
production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and
business interruptions resulting from geopolitical actions, including war and terrorism, or natural disasters, including earthquakes, hurricanes or typhoons, floods, and fires.
Our internal computer systems, or those of our CROs, CMOs, CSO, or other contractors or consultants, may fail or suffer security breaches, which could result in a material disruption of our drug development programs.
Despite the implementation of security measures, our internal computer systems and those of our CROs, CMOs, and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war, and telecommunication and electrical failures. While we are not aware of any such system failure, accident, or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our drug development programs or commercialization efforts. For example, the loss of clinical study data from completed or ongoing clinical studies for any of our product candidates could result in delaysthe United States, we must demonstrate with substantial evidence from adequate and well-controlled clinical studies, and to the satisfaction of the FDA, that such product candidates are safe and effective for their intended uses. Results from preclinical studies and clinical studies can be interpreted in different ways. Even if we believe the preclinical or clinical data for our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. While we back-up our internal computer systems periodically and storeproduct candidates are promising, such data off-site or inmay not be sufficient to support approval by the cloud, we can offer no assurance that such off-site storage of data will allow us to continue our business without interruptions to our operations, which could result in a material disruption of our drug development programs or commercialization efforts. To the extent thatFDA. Administering any disruption or security breach were to result in a loss of or damage to our data or applications, or inappropriate

disclosure of confidential or proprietary information, we could incur liability and the further development of our product candidates to humans may produce undesirable side effects, which could interrupt, delay, or cause suspension of clinical studies of our product candidates and result in the denial of approval of our product candidates for any or all targeted indications.
FDA approval of an NDA is not guaranteed, and the approval process is expensive and may take several years. The FDA also has substantial discretion in the approval process. Despite the time and expense we invest, failure can occur at any stage, and we could encounter problems that require us to repeat clinical studies, perform additional preclinical studies and clinical studies, or abandon development and commercialization of a product candidate altogether. The number of preclinical studies and clinical studies that will be delayed.required for FDA approval varies depending on, among other factors, the product candidate, the disease or condition that the product candidate is designed to address, and the
Risks generally associated

regulations applicable to any particular product candidate. The FDA can delay, limit, or deny approval of a product candidate for many reasons, including, but not limited to:
disagreement with a company-widethe design or implementation of information systems, includingour clinical trials;
failure of clinical trials to show the level of statistical significance or clinical meaningfulness needed for approval;
failure to demonstrate that a product candidate is safe or effective;
insufficient data from preclinical and clinical studies to support an enterprise resource planning (ERP) system, may adversely affectapplication;
a finding by an institutional review board, or IRB, Data Safety Monitoring Board, or DSMB, Data Monitoring Committee, or DMC, or the FDA that the clinical trial exposes subjects or patients to an unacceptable health risk;
disapproval of our or our third-party manufacturer’s processes or facilities; or
changes to FDA’s approval policies or regulations.
If any of our product candidates fails to demonstrate safety and efficacy in clinical studies or does not gain regulatory approval, our business and results of operations orwill be materially and adversely harmed.
If the requirements for approval of ADS-5102 under Section 505(b)(2) are not as we expect, approval will likely take significantly longer, cost significantly more, and entail significantly greater complications and risks than anticipated, and in any case may not be successful. Similar obstacles may arise in other countries.
Similar to the approval pathway for GOCOVRI, we are developing ADS-5102, with the expectation that it will be eligible for approval through the Section 505(b)(2) regulatory pathway. Section 505(b)(2) of the FDCA allows an NDA to rely in part on the FDA’s prior conclusions regarding the safety and effectiveness of our internal controls overan approved drug product, or reference listed drug, or RLD. Use of the Section 505(b)(2) regulatory pathway could potentially decrease the amount of preclinical and/or clinical data that we would need to generate in order to obtain FDA approval. If the FDA does not allow us to pursue the Section 505(b)(2) regulatory pathway as anticipated, we may need to conduct additional clinical trials, provide additional data and information, and meet additional standards for product approval. If this were to occur, the time and financial reporting.
In support of our anticipated growth and future commercial-stage operations, we intendresources required to select and implement a number of company-wide information systems, including adding new functionality to our enterprise resource planning (“ERP”), and other similar systems. Many of these systems are complex and their successful and timely implementation is not assured, requires significant capital expenditures, and can be disruptive to our business operations. We recently implemented a new ERP system in addition to a new human resource information system (“HRIS”). These projects required and may continue to require investment of capital and human resourcesobtain FDA approval, and the attention of many employees whocomplications and risks associated with regulatory approval would otherwise be focused on other aspects oflikely substantially increase. Moreover, our business. Any deficiencies ininability to pursue the design and implementation of the new ERP and HRIS system couldSection 505(b)(2) regulatory pathway may result in potentially much higher costs thancompetitive products reaching the market more quickly, which would adversely impact our competitive position and prospects. Even if we had incurred and could adversely affect our abilityare able to utilize the Section 505(b)(2) regulatory pathway, there is no guarantee that utilizing this pathway will ultimately lead to faster product development or earlier approval for any product that we may attempt to develop and launch solutions, provide services, fulfill contractual obligations, file reports with the SEC in a timely manner, operate our business, or otherwise affect our controls environment. Any of these consequences could have an adverse effect on our results of operations and financial condition.commercialize.
Risks related to intellectual property
Our ability to successfully commercialize our technologyGOCOVRI, ADS-5102, and productsany product candidates may be materially adversely affected if we are unable to obtain and maintain effective intellectual property rights for our technologiesproducts and product candidates.
Our success depends in large part on our ability to obtain and maintain patentexclusivity, patent(s), and other intellectual property protection in the United States and in other countries with respect to GOCOVRI, ADS-5102, our proprietary technologyproduct candidates, and products. In some circumstances, we may not have the right to control the preparation, filing,any in- and prosecution of patent applications, or to maintain or enforce the patents, covering technology or products that we license to third parties or that we may license from third parties. Therefore, we cannot be certain that these patents and applications will be prosecuted and enforced in a manner consistent with the best interests of our business. In addition, if third parties who license patents to us or from us fail to maintain such patents, or lose rights to those patents, the rights we have licensed may be reduced or eliminated.
out-licensed programs. We have sought to protect GOCOVRI, ADS-5102, and our proprietary positionproduct candidate(s) by filing patent applications in the United States and abroad related to our novel discoveries, technologies, and products that are important to our business. This process is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. In addition, we may not pursue or obtain patent protection in all relevant markets. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection. Our pending and future patent applications may not result in patents being issued which protect our technology or products, in whole or in part. In addition, our existing patents and any future patents we obtain may not be sufficiently broad to prevent others from using our discoveries or technologies or from developing competing products and technologies.

The patent position of pharmaceutical and biotechnology companies generally is highly uncertain and involves complex legal and factual questions for which many legal principles remain unresolved. In recent years, patent rights have been the subject of significant litigation. As a result, the issuance, scope, validity, enforceability, and commercial value of our patent rights are highly uncertain. Our pending and future patent applications may not result in patents being issued in the United States or in other jurisdictions which protect our technology or products or which effectively prevent others from commercializing competitive technologies and products. Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may diminish the value of our patents or narrow the scope of our patent protection. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot be certain that we were the first to make the inventions claimed in our patents or pending patent applications, or that we were the first to file for patent protection of such inventions. In addition, the United States Patent and Trademark Office, or USPTO, might require that the term of a patent issuing from a pending patent application be disclaimed and limited to the term of another patent that is commonly owned or names a

common inventor. As a result, the issuance, scope, validity, enforceability, and commercial value of our patent rights is highly uncertain.
Recent or futureThe United States has enacted and implemented wide-ranging patent reform legislation could increaselegislation. The United States Supreme Court has ruled on several patent cases in recent years, either narrowing the uncertainties and costs surroundingscope of patent protection available in certain circumstances or weakening the prosecutionrights of patent owners in certain situations. In addition to increasing uncertainty with regard to our patent applications andability to obtain patents in the enforcement or defensefuture, this combination of our issued patents. In March 2013, underevents has created uncertainty with respect to the Leahy-Smith America Invents Act, or America Invents Act,value of patents, once obtained. Depending on actions by the United States moved from a “firstCongress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to invent”obtain new patents or to a “first-to-file” system. Under a “first-to-file” system, assumingenforce patents that we have licensed or that we might obtain in the other requirements for patentability are met, the first inventor to file a patent application generally will be entitled to a patent on the invention regardless of whether another inventor had made the invention earlier. The America Invents Act includes a number of other significantfuture. Similarly, changes to U.S.in patent law including provisionsand regulations in other countries or jurisdictions or changes in the governmental bodies that affectenforce them or changes in how the wayrelevant governmental authority enforces patent applications are prosecuted, redefine prior art and establish alaws or regulations may weaken our ability to obtain new post-grant review system. The effects of these changes are currently unclear, aspatents or to enforce patents that we have licensed or that we may obtain in the USPTO only recently developed new regulations and procedures in connection with the America Invents Act and many of the substantive changes to patent law, including the “first-to-file” provisions, only became effective in March 2013. In addition, the courts have only recently started to address these provisions such that the law is still developing, and the applicability of the act and new regulations on specific patents discussed herein have not been determined and would need to be reviewed. However, the America Invents Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business and financial condition.future.
From time to time, we may become involved in opposition, interference, derivation, inter partes review, post-grant review, or other proceedings challenging our patent rights or the patent rights of others, and the outcome of any proceedings are highly uncertain. An adverse determination in any such proceeding could reduce the scope of, or invalidate, our patent rights, allow third parties to commercialize our technology or products and compete directly with us or Allergan, without payment to us.
Even if our patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors from competing with us, or otherwise provide us with any competitive advantage. Our competitors may be able to circumvent our owned or licensed patents by developing similar or alternative technologies or products in a non-infringing manner. The issuance of a patent is not conclusive as to its scope, validity, or enforceability, and our owned and licensed patents may be challenged in the courts or patent offices in the United States and abroad. Such challenges may result in the patent claims of our owned or licensed patents being narrowed, invalidated, or held unenforceable, which could limit our ability to stop or prevent us from stopping others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology and products. Given the amount of time required for the development, testing, and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours or otherwise provide us with a competitive advantage.
For our partnered assets, like Namzaric, we may not have the right to control the prosecution of patent applications, or to maintain or enforce the patent, covering our products or product candidates that we license to third parties or that we may license from third parties. Therefore, we cannot be certain that these patents and applications will be prosecuted and enforced in a manner consistent with the best interests of our business. In addition, if third parties who license patents to us or from us fail to maintain such patents, or lose rights to those patents, the rights we have licensed may be reduced or eliminated.
43

We may not be able to protect our intellectual property rights throughout the world.
Filing, prosecuting, and defending patents on all of our products and product candidates throughout the world would be prohibitively expensive. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we have patent protection but where enforcement is not as strong as in the United States. These products may compete with our products and product candidates in jurisdictions where we do not have any issued patents, and our patent claims or other intellectual property rights may not be effective or sufficient to prevent them from so competing. Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to biopharmaceuticals, which could make it difficult for us to stop the infringement of our patents or marketing of competing products against third parties in violation of our proprietary rights generally. The initiation of proceedings by third parties to enforce our patent rights in foreign jurisdictions could result in substantial cost and divert our efforts and attention from other aspects of our business.

Obtaining and maintaining our patent protection depends upon compliance with various procedural, document submission, fee payment, and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.
The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment, and other provisions during the patent prosecution process and following the issuance of a patent. Our failure to comply with such requirements could result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would otherwise have been the case if our patent were in force.
We may become involved in lawsuits or other proceedings to protect or enforce our patents or other intellectual property, which could be expensive, time-consuming, and unsuccessful.if unsuccessful could materially harm our business.
Competitors may infringe or otherwise violate our patents, trademarks, copyrights or other intellectual property.property for GOCOVRI and ADS-5102, our partnered products, any product candidates, and any in- and out-licensed programs. To counter infringement or unauthorized use, we or our licensees may be required to file infringement claims, which can be expensive and time-consuming. For example, we, Forest, Forest Laboratories, Inc., Merz Pharma GmbH & Co. KGaA,on February 16, 2018, Osmotica Pharmaceuticals LLC and MerzVertical Pharmaceuticals GmbHLLC (“Osmotica”) filed patent infringement lawsuits under Forest’s patentsan action against us in U.S. District Court for the state of Delaware, requesting a declaratory judgment that Osmotica’s newly-approved product Osmolex ER™ (amantadine) extended release tablets does not infringe certain of our patents. For further information, see Litigation and patents owned by usOther Legal Proceedings in “Note 7 – Commitments and licensedContingencies” in the accompanying “Notes to Forest, against several manufacturers of generic pharmaceuticals that have filed ANDAs with the FDA seeking approval to manufacture and sell generic versions of Namzaric® and Namenda XR®Condensed Consolidated Financial Statements (unaudited)”.
We anticipate that the prosecution of theany lawsuits willrelated to our partnered products and any lawsuits related to GOCOVRI may require a significant amount of time and attention offrom our chief executive officersenior executives and other senior executives.management. In addition, in a patent infringement proceeding, a court may decide that a patent of ours (or a patent we license) is invalid or unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technologyproduct in question. An adverse result in any of the Forest litigations or any other litigation or proceeding could put one or more of our patents at risk of being invalidated or interpreted narrowly. Such a result could limit our ability to prevent others from using or commercializing similar or identical technology and products, limit our ability to prevent others from launching generic versions of our products and could limit the duration of patent protection for our products, all of which could have a material adverse effect on our business. AAlso, a successful challenge to our patents could reduce or eliminate our right to receive royalties from Forest.Allergan under our license agreement with Allergan. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.
Third parties may initiate legal proceedings alleging that we or our partners are infringing their intellectual property rights, the outcome of which would be uncertain and could have a material adverse effect on the success of our business.
Our commercial success depends upon our ability and the ability of our partners to develop, manufacture, market, and sell our products and product candidates and to use our proprietary discoveries and technologies without
44

infringing, misappropriating, or otherwise violating the proprietary rights or intellectual property of third parties. We or our partners may become party to, or be threatened with, future adversarial proceedings or litigation regarding intellectual property rights with respect to our products and technology, including interference, derivation, re-examination, inter partes review, post-grant review, opposition, or similar proceedings before the USPTO and its foreign counterparts. The costs of these proceedings could be substantial, and the proceedings may result in a loss of such intellectual property rights. Some of our competitors may be able to sustain the costs of complex patent disputes and litigation more effectively than we can, because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any disputes or litigation could adversely affect our ability to raise the funds necessary to continue our operations. Third parties may assert infringement claims against us or our partners based on existing patents or patents that may be granted in the future. Under our license agreement with Allergan we are obliged to indemnify Allergan under certain circumstances and our royalty entitlements may also be reduced. Our indemnification obligation to Allergan, while subject to customary limitations, has no monetary cap, and our right to receive royalties from Allergan may be eliminated in any calendar quarter in which certain third party generic competition exists. If we or our partners are found to infringe a third-party’s intellectual property rights, we could be required to obtain a license from such third-party to continue developing and marketing our products and technology. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We could be forced, including by court order, to cease commercializing the infringing technology or product. In addition, we could be found liable for monetary damages. A finding of infringement could prevent us from commercializing our products and product candidates or force us to cease

some of our business operations, which could materially harm our business. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business.
We may be unable to protect the confidentiality of our trade secrets, thus harming our business and competitive position.
In addition to our patented technology and products, we rely upon trade secrets, including unpatented know-how, technology, and other proprietary information, to develop and maintain our competitive position, which we seek to protect, in part, by confidentiality agreements with our employees, our partners, and consultants. We also have agreements with our employees and selected consultants that obligate them to assign their inventions to us. However, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual property to execute such agreements, we may be unsuccessful in executing such an agreement with each party who in fact conceives or develops intellectual property that we regard as our own. In addition, it is possible that technology relevant to our business will be independently developed by a person that is not a party to such an agreement.
While to our knowledge the confidentiality of our trade secrets has not been compromised, if the employees, consultants or partners that are parties to these agreements breach or violate the terms of these agreements, we may not have adequate remedies for any such breach or violation, and we could lose our trade secrets through such breaches or violations. Further, our trade secrets could be disclosed, misappropriated, or otherwise become known or be independently discovered by our competitors. In addition, intellectual property laws in foreign countries may not protect our intellectual property to the same extent as the laws of the United States. If our trade secrets are disclosed or misappropriated, it would harm our ability to protect our rights and adversely affect our business.
Risks related to Namzaric®
Under our license agreement with Allergan, if Allergan fails to successfully commercialize Namzaric for any reason or if the license agreement with Allergan is terminated, the potential royalties we are eligible to receive under our license agreement with Allergan may not occur or may be minimal, and would have a negative impact on our revenue potential and harm our business. 
In November 2012, we entered into a license agreement with Allergan pursuant to which we granted Allergan a right to develop and commercialize Namzaric in the United States. Under that agreement, we expect to receive future royalties from Allergan on the net sales of Namzaric, starting in May 2020. If for any reason Allergan fails to successfully commercialize Namzaric, on which we are eligible to receive royalties in the low double digits to mid-teens, we may not receive such future royalties or receive minimal amounts, and our business may be harmed. Even if we do receive royalties, based on 2019 net sales of Namzaric, we expect the tiered royalty to be in the low double digits through the term of the agreement.
45

We are the subject of litigation claiming violation of Federal and state false claims acts in connection with the commercialization of Namenda XR and Namzaric by Allergan, whichmay have a material and negative impact on our business.
On April 1, 2019, we were served with a complaint against us 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, as further described in Litigation and Other Legal Proceedings in “Note 7 – Commitments and Contingencies” in the accompanying “Notes to Condensed Consolidated Financial Statements (unaudited)”. The complaint alleges that patents held by Allergan and us 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. The complaint includes a claim for damages of “potentially more than $2.5 billion dollars,” treble damages and statutory penalties. We are in the early stages of this litigation. Defending this litigation may be costly, divert time and attention of our management from the conduct of our business, and if we are unable to prevail in this litigation it may result in substantial damages, each of which could have a material and negative impact on our business.
Risks related to our financial condition and need for additional capital
Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations.
Our quarterly and annual operating results have fluctuated significantly, and we expect may fluctuate significantly in the future, particularly in light of the COVID-19 pandemic and the effect that it is having on patient demand and the economy as a whole, which makes it difficult for us to predict our future operating results. Any future revenue will depend on our ability to market and sell GOCOVRI, ADS-5102 and our product candidate, the payment of royalties to us from Allergan under terms of our licensing agreement regarding Namzaric, or the establishment of potential future collaboration and license agreements, if any, and the achievement of any upfront or milestone payments provided thereunder. Furthermore, our operating results may fluctuate due to a variety of other factors, many of which are outside of our control and may be difficult to predict, including: 
uncertainties related to, and the duration of, the COVID-19 pandemic;
the level of demand for our products, which may vary significantly as they are launched and compete for position in the marketplace;
pricing and reimbursement policies with respect to GOCOVRI, ADS-5102 and our product candidate, if approved, and the competitive response from existing and potential future therapeutic approaches that compete with our products and product candidate;
the cost of manufacturing our products and product candidate, which may vary due to a number of factors, including the terms of our agreements with contract manufacturing organizations, or CMOs;
the timing, cost, level of investment, and success or failure of research and development activities relating to our products and product candidate, which may change from time to time;
expenditures that we may incur to acquire and develop additional product candidates and technologies;
the timing and success or failure of clinical studies for competing product candidates, or any other change in the competitive landscape of our industry, including consolidation among our competitors or partners;
the timing and magnitude of upfront and milestone payments under any potential future collaboration and licensing agreements;
future accounting pronouncements or changes in our accounting policies; and
changing or volatile U.S., European, and global economic environments, especially as a result of the COVID-19 pandemic.
The cumulative effects of these factors could result in large fluctuations and unpredictability in our quarterly and annual operating results. As a result, comparing our operating results on a period-to-period basis may not be
46

meaningful. Investors should not rely on our past results as an indication of our future performance. This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our operating results fall below the expectations of analysts or investors or below any forecasts we may provide to the market, or if the forecasts we provide to the market are below the expectations of analysts or investors, the price of our common stock could decline substantially. Such a stock price decline could occur even when we have met any previously publicly stated operating results and/or earnings guidance that we may provide.
If we donot have adequate funds to cover all of our development and commercial activities, we may have toraise additional capital orcurtail or cease operations.
We began to commercialize GOCOVRI for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications, in January 2018, and it will require substantial funds to continue to commercialize GOCOVRI. In addition, funds are required for the continued operation of our business. We have entered into a Sales Agreement with Cowen and Company, LLC under which we may offer and sell our common stock having aggregate sales proceeds of up to $50 million from time to time through Cowen and Company, LLC as our sales agent. As of March 31, 2020, we have not made any sales under this facility. As of March 31, 2020, we had approximately $115.3 million in cash, cash equivalents, and investments. We believe that our available cash, cash equivalents, and investments will be sufficient to fund our anticipated level of operations for at least the next 12 months, but there can be no assurance that this will be the case, especially in light of the uncertainties related to, and the duration of, the COVID-19 pandemic.
We have financed our operations primarily through proceeds from our license agreement with Allergan, public and private equity offerings, our royalty-backed loan agreement (“Royalty-Backed Loan”) with HealthCare Royalty Partners III, L.P., (“HCRP”), since 2017 with sales of GOCOVRI, and, to a lesser extent, government grants, venture debt, and benefits from tax credits made available under a federal stimulus program supporting drug development. We anticipate that our cash requirements will be substantial as we:
commercialize GOCOVRI, including distribution, marketing, and sales capabilities;
manufacture GOCOVRI for commercial use;
investigate ADS-5102 in preclinical and clinical trials for the treatment of walking impairment in patients with MS, and potentially other indications;
seek regulatory approvals for our products and any product candidates that successfully complete clinical studies;
continue the research, development, and manufacture of our current products and product candidate; and
seek to discover or in-license additional product candidates.
If we do not have adequate funds to support these activities, our business opportunities could be hindered. 
If we need additional funds to operate our business andif we cannot raise additional capital when needed, or if additional capital is not available to us on favorable terms, our stockholders may be adversely affected or our business may be harmed.
If we need additional funds to support our business and additional funding is not available on favorable terms or at all, we may need to delay or reduce the scope of our research and clinical development programs or commercialization efforts. We do not have any committed external source of funds or other support for our development efforts. We expect to finance future cash needs through a combination of public or private equity offerings, debt financings, royalty financings, collaborations, strategic alliances, licensing arrangements, asset sales, and other marketing and distribution arrangements. The trading prices for our common stock, as well as the broader equity and debt markets, have been highly volatile since the advent of the COVID-19 pandemic. Additional financing may not be available to us when we need it or it may not be available on favorable terms. If we raise additional capital through debt financings, royalty financings, collaborations, strategic alliances, or licensing arrangements with third parties, we may have to relinquish certain valuable rights to our products and product candidate, technologies, future revenue streams, or research programs or grant licenses on terms that may not be favorable to us. If we raise additional capital through equity offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, in
47

addition to the repayment of principal and interest on negotiated terms, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the scope of, or suspend one or more of our clinical studies or research and development programs or our commercialization efforts.
We have outstanding debt backed by two of our principal assets, GOCOVRI and royalties we may receive on Namzaric, and failure by us or our royalty subsidiary to fulfill our obligations under the applicable loan agreements may cause the repayment obligations to accelerate.
In May 2017, we, through a newly formed wholly-owned subsidiary, entered into a Royalty-Backed Loan with HCRP, pursuant to which we initially borrowed $35 million and then borrowed an additional $65 million upon FDA approval and FDA’s recognition in the Orange Book of the seven-year orphan drug exclusivity that GOCOVRI earned upon approval in August 2017, for the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications.
Interest and principal on the loan will be payable from the proceeds of royalty on U.S. net sales of GOCOVRI and up to $15 million of our annual royalties from Allergan on U.S. net sales of Namzaric starting in May 2020. The HCRP notes mature in December 2026, if not earlier repaid.
We secured the loan with rights to GOCOVRI (ADS-5102) and rights to certain payment amounts on Namzaric and the loan documents further provide for assignment into our subsidiary holding these rights to any future intellectual property, licenses, assets and agreements with respect to the manufacture, development, supply, distribution, sale and commercialization of GOCOVRI. The loan documents contain customary events of default permitting HCRP to accelerate and require mandatory prepayment of outstanding principal and interest, including: failure to timely pay principal and interest when due and payable; failure to perform specified covenants with respect to maintenance of the collateral and prohibitions on liens with respect to the collateral; limitations on payments of dividends, additional loans, acquisition or merger transactions not in accordance with the arrangement. Upon the occurrence, an event of default under the loan documents, we could be required to prepay the entire loan and, if we are not able to do so, we may lose control over certain rights and payments to GOCOVRI and royalty payments with respect to Namzaric, either of which would seriously harm our business.
We are and in the future may be subject to securities litigation, which may be expensive and could divert management attention.
Our share price is volatile, and in the past companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We have become the target of this type of litigation and in May 2019 a putative class action lawsuit alleging violations of the federal securities laws was filed against us and certain of our current and former directors and officers alleging violations of the securities laws by us and certain of our current and former directors and officers in connection with our January 2018 secondary public offering of common stock. In addition, in December 2019, another putative class action lawsuit was filed against us and certain former officers alleging violations of the Securities Act of 1934. For more information, please see Litigation and Other Legal Proceedings in “Note 7 – Commitments and Contingencies” in the accompanying “Notes to Condensed Consolidated Financial Statements (unaudited)”. Lawsuits such as this one can be expensive to defend and could divert our management’s attention from the conduct of our business, which could have an adverse effect on our business.
Risks related to ownership of our common stock
Our stock price may be volatile, and purchasers of our common stock could incur substantial losses.
Our stock price has fluctuated in the past and may be volatile in the future. The stock market in general and the market for securities of pharmaceutical and biotechnology companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, investors may experience losses on their investments in our stock.
In addition, the clinical development stage of our operations may make it difficult for investors to evaluate the success of our business to date and to assess our future viability. The market price for our common stock may be influenced by many factors, including:
48

uncertainties related to, and the duration of, the COVID-19 pandemic;
our success in commercializing GOCOVRI for the treatment of dyskinesia in patients with Parkinson’s disease;
the availability of reimbursement by third-party payers at acceptable levels, or at all, for GOCOVRI;
the success of competitive products or technologies;
results of clinical studies of our product candidates or those of our competitors;
introductions and announcements of new products and product candidates by us, our commercialization partners, or our competitors, and the timing of these introductions or announcements;
actions taken by regulatory agencies with respect to our or our competitors’ products, product candidates, clinical studies, manufacturing process, or sales and marketing terms;
variations in our financial results or those of companies that are perceived to be comparable to us;
our revenue performance, both in absolute terms and relative to analyst and shareholder expectations;
the success of our efforts to acquire or in-license additional products or product candidates;
developments concerning our collaborations, including but not limited to those with our sources of manufacturing and our commercialization partners;

announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures, or capital commitments;
developments or disputes concerning patents or other proprietary rights, including patents, litigation matters, and our ability to obtain patent protection for our current or future products;
our ability or inability to raise additional capital and the terms on which we raise it;
the recruitment or departure of key personnel;
changes in the structure of healthcare reimbursement systems;
regulatory or legal developments in the United States and other countries, especially changes in laws or regulations applicable to our current or future products;
market conditions in the pharmaceutical and biotechnology sectors;
actual or anticipated changes in revenue forecasts, earnings estimates or changes in stock market analyst recommendations regarding our common stock, other comparable companies or our industry generally;
trading volume of our common stock;
sales of our common stock by us or our stockholders;
general economic, industry, and market conditions; and
the other risks described in this “Risk Factors” section.
These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance. Additionally, following periods of volatility in the market, securities class-action litigation has often been instituted against companies. Such litigation, if instituted against us, could result in substantial costs and diversion of management’s attention and resources, which could materially and adversely affect our business, financial condition, results of operations, and growth prospects.
Sales of a substantial number of shares of our common stock in the public market by our existing stockholders could cause our stock price to fall.
Sales of a substantial number of shares of our common stock in the public market, or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of our common stock.
Concentration of ownership of our common stock among our existing executive officers, directors, and principal stockholders may prevent new investors from influencing significant corporate decisions.
Our executive officers, directors and current beneficial owners of 5% or more of our common stock, in the aggregate, beneficially own a significant percentage of our outstanding common stock. These persons, acting together, will be able to significantly influence all matters requiring stockholder approval, including the election and removal of directors and any merger or other significant corporate transactions. The interests of this group of stockholders may not coincide with the interests of other stockholders.
We will continue to incur increased costs and demands upon management as a result of complying with the laws and regulations affecting public companies, and we could fail to successfully improve our systems, procedures, and controls, which could affect our operating results.
As a public company, we will continue to incur legal, accounting and other expenses associated with reporting requirements and corporate governance requirements, including requirements under the Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, as well as new rules implemented by the SEC and the NASDAQ Stock Market LLC. We expect that we will need to continue to improve existing, and implement new operational, financial, and information management systems, procedures, and controls to manage our business effectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures,

or controls may cause our operations to suffer and we may be unable to conclude that our internal control over financial reporting is effective.
An active trading market for our common stock may not be maintained.
Our stock is currently traded on NASDAQ, but we can provide no assurance that we will be able to maintain an active trading market on NASDAQ or any other exchange in the future or that the daily trading volume will be adequate to allow orderly purchases or sales of our common stock without significantly impacting the price per share. If an active market for our common stock is not maintained, it may be difficult for our stockholders to sell shares without depressing the market price for the shares or at all.
If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about us or our business, our stock price and trading volume could decline.
The trading market for our common stock depends, in part, on the research and reports that securities or industry analysts publish about us or our business. Securities and industry analysts may cease to publish research on our company at any time in their discretion. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading volume to decline. In addition, if one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. If our operating results fail to meet the forecast of analysts, our stock price will likely decline.
Provisions in our corporate charter documents and under Delaware law could make an acquisition of us more difficult and may prevent attempts by our stockholders to replace or remove our current management.
Provisions in our corporate charter and our bylaws may discourage, delay, or prevent a merger, acquisition, or other change in control of us that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In
49

addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. Because our board of directors is responsible for appointing the members of our management team, these provisions could in turn affect any attempt by our stockholders to replace current members of our management team. Among others, these provisions include that:
our board of directors is divided into three classes with staggered three-year terms, which may delay or prevent a change of our management or a change in control;
our board of directors has the right to change the size of our board of directors and to elect directors to fill a vacancy created by the expansion of the board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors;
our stockholders may not act by written consent or call special stockholders’ meetings; as a result, a holder, or holders, controlling a majority of our capital stock would not be able to take certain actions other than at annual stockholders’ meetings or special stockholders’ meetings called by the board of directors or the chairman of the board and chief executive officer;
our certificate of incorporation prohibits cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;
stockholders must provide advance notice and additional disclosures in order to nominate individuals for election to the board of directors or to propose matters that can be acted upon at a stockholders’ meeting, which may discourage or deter a potential acquiroracquirer from conducting a solicitation of proxies to elect the acquiror’sacquirer’s own slate of directors or otherwise attempting to obtain control of our company; and
our board of directors may issue, without stockholder approval, shares of undesignated preferred stock, and the ability to issue undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to acquire us.

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.
Because
Other Risks
Our ability to use net operating losses to offset future taxable income may be subject to limitations.
As of December 31, 2019, we dohad federal and state net operating loss carryforwards of $354.4 million and $325.8 million, respectively. The federal net operating loss carryforwards will begin to expire, if not anticipate paying any cash dividends onutilized, beginning in 2025, and the state net operating loss carryforward begins expiring in 2028. These net operating loss carryforwards could expire unused and be unavailable to offset future income tax liabilities. Under the newly enacted federal income tax law, federal net operating losses incurred in 2018 and in future years may be carried forward indefinitely, but the deductibility of such federal net operating losses is limited. It is still uncertain if and to what extent various states will conform to the newly enacted federal tax law. In addition, under Section 382 of the Internal Revenue Code of 1986, as amended, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income or taxes may be limited. It is possible that we have experienced an ownership change limitation. We may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. If an ownership change occurs and our ability to use our net operating loss carryforwards is materially limited, it would harm our future operating results by effectively increasing our future tax obligations.
50

We are a “smaller reporting company” and we cannot be certain whether the reduced reporting requirements applicable to smaller reporting companies will make our common stock less attractive to investors.
We are a “smaller reporting company” and, as such, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not smaller reporting companies, including reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may suffer or be more volatile.
Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.
Our operations have been affected by the COVID-19 pandemic and could be subject to earthquakes, power shortages, telecommunications failures, floods, hurricanes, fires, extreme weather conditions, other medical epidemics, and other natural or manmade disasters or business interruptions. The duration of the COVID-19 pandemic and the occurrence of any of these other business disruptions could seriously harm our operations and financial condition and increase our costs and expenses. Our corporate headquarters is located in California and certain clinical sites for our product candidates, operations of our existing and future partners, and suppliers are or will be located near major earthquake faults and fire zones. The ultimate impact on us, our significant partners, suppliers, and our general infrastructure of being located near major earthquake faults and fire zones and being consolidated in certain geographical areas is unknown, but our operations and financial condition could suffer in the foreseeableevent of a major earthquake, fire, or other natural or manmade disaster.
Any future capital appreciation, ifoperations or business arrangements with entities outside the United States present risks that could materially adversely affect our business.
If we obtain approval to commercialize any approved products or utilize CMOs outside of the United States, a variety of risks associated with international operations could materially adversely affect our business. If any product or product candidates that we may develop are approved for commercialization outside the United States, we will be our stockholders’ sole sourcesubject to additional risks related to entering into international business relationships, including:
impacts of gain.the COVID-19 pandemic;
We have never declareddifferent regulatory requirements for drug approvals in foreign countries;
reduced protection for intellectual property rights;
unexpected changes in tariffs, trade barriers, and regulatory requirements;
different payer reimbursement regimes, governmental payers or paid cash dividends on ourpatient self-pay systems and price controls;
economic weakness, including inflation or political instability in particular foreign economies and markets;
difficulties in assuring compliance with foreign corrupt practices laws;
compliance with tax, employment, immigration, and labor laws for employees living or traveling abroad;
foreign taxes, including withholding of payroll taxes;
foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incident to doing business in another country;
workforce uncertainty in countries where labor unrest is more common stock. We currently intend to retain allthan in the United States;
compliance with privacy laws;
production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and
business interruptions resulting from geopolitical actions, including war and terrorism, or natural disasters, including earthquakes, hurricanes or typhoons, floods, and fires.
51

Our internal computer systems, or those of our future earnings,CROs, CMOs, or other contractors or consultants, may fail or suffer security breaches, which could result in a material disruption of our business.
Despite the implementation of security measures, our internal computer systems and those of our CROs, CMOs, specialty pharmacy, distributors, and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war, and telecommunication and electrical failures. While we are not aware of any material system failure, accident, or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our drug development programs or commercialization efforts. For example, the loss of clinical study data from completed or ongoing clinical studies for any of our products or product candidates could result in delays in our regulatory approval efforts and significantly increase our costs to financerecover or reproduce the growthdata. While we back-up our internal computer systems periodically and store such data off-site or in the cloud, we can offer no assurance that such off-site storage of data will allow us to continue our business without interruptions to our operations, which could result in a material disruption of our drug development programs or commercialization efforts. To the extent that any disruption or security breach were to result in a loss of or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development of our business. In addition, the termsproducts and product candidates could be delayed.
52

Table of existing or any future debt agreements may preclude us from paying dividends. As a result, capital appreciation, if any, of our common stock will be our stockholders’ sole source of gain for the foreseeable future.Contents
