Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Significant accounting policies followed in the preparation of these financial statements are as follows: Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity date at the date of purchase of three months or less to be cash equivalents. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported in the consolidated balance sheets that sum to the total of the same such amounts shown in the consolidated statements of cash flows (in thousands): Twelve Months Ended Twelve Months Ended Beginning of period End of period Beginning of period End of period Cash and cash equivalents $ 188,657 $ 319,589 $ 114,846 $ 188,657 Restricted cash 5,770 8,770 5,770 5,770 Total cash, cash equivalents and restricted $ 194,427 $ 328,359 $ 120,616 $ 194,427 Investment Securities Currently, all of the Company’s investment securities are debt securities. The Company has classified all of its investment securities as available-for-sale as the sale of such securities may be required prior to maturity to implement management strategies, and accordingly, carries these investments at fair value. Unrealized gains and losses, if any, are reported as a separate component of stockholders’ equity. The cost of investment securities classified as available-for-sale is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion are included in interest income. Realized gains and losses, if any, are also included in interest income. The cost of securities sold is based on the specific identification method. Fair Value of Financial Instruments The carrying values of the Company’s financial instruments, consisting of cash and cash equivalents, trade receivables, interest and other receivables, restricted cash, and accounts payable and accrued liabilities, approximate fair value due to the relative short-term nature of these instruments. As disclosed in Note 4, the Company classifies its cash equivalents and available-for-sale investment securities within the fair value hierarchy as defined by authoritative guidance: Level 1 Inputs — Quoted prices for identical instruments in active markets. Level 2 Inputs — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable. Level 3 Inputs — Valuation derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Accounts Receivable Accounts receivable are recorded net of customer allowances for distribution fees, prompt payment discounts, chargebacks, and credit losses. Allowances for distribution fees, prompt payment discounts and chargebacks are based on contractual terms. The Company estimated the current expected credit losses of its accounts receivable by assessing the risk of loss and available relevant information about the collectability, including historical credit losses, existing contractual payment terms, actual payment patterns of its customers, individual customer circumstances, and reasonable and supportable forecast of economic conditions expected to exist throughout the contractual life of the receivable. Based on its assessment, as of December 31, 2024 and 2023, the Company has determined that an allowance for credit loss was not required. Inventory Inventory is stated at the lower of cost or net realizable value under the first-in, first-out method (FIFO). The Company uses a combination of standard and actual costing methodologies to determine the cost basis for its inventories which approximates actual costs. Inventory consists of raw material, work in process, and finished goods, including third-party manufacturing costs, freight, and indirect overhead costs. The Company capitalizes inventory costs associated with its products upon regulatory approval when, based on management’s judgment, future commercialization is considered probable and the future economic benefit is expected to be realized; otherwise, such costs are expensed. Prior to FDA approval of NUPLAZID in April 2016 and DAYBUE and March 2023, all costs related to the manufacturing of NUPLAZID and DAYBUE were charged to research and development expense in the period incurred. The Company periodically reviews inventory and reduces the carrying value of items to net realizable value for potentially excess, dated or obsolete inventory based on an analysis of forecasted demand compared to quantities on hand and any firm purchase orders, as well as product shelf life. During the years ended December 31, 2024, 2023 and 2022, the Company recorded charges of $ 0.5 million, $ 0.9 million and $ 0.6 million, respectively, to reduce certain finished goods and work in process inventory to its net realizable value. Property and Equipment Property and equipment are recorded at cost and depreciated over their estimated useful lives using the straight-line method. Leasehold improvements are amortized over the shorter of their estimated useful lives or the term of the lease by use of the straight-line method. Construction-in-process reflects amounts incurred for property, equipment or improvements that have not been placed in service. Maintenance and repair costs are expensed as incurred. When assets are retired or sold, the assets and accumulated depreciation are removed from the respective accounts and any gain or loss is recognized. Estimated useful lives by major asset category are as follows: Useful Lives Machinery and equipment 5 to 7 years Computers and software 3 years Furniture and fixtures 10 years Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Through December 31, 2024, no suc h impairment losses have been recorded by the Company. License Fees and Royalties The Company expenses amounts paid to acquire licenses associated with products under development when the ultimate recoverability of the amounts paid is uncertain and the technology has no alternative future use when acquired. Acquisitions of technology licenses are charged to expense or capitalized based upon management’s assessment regarding the ultimate recoverability of the amounts paid and the potential for alternative future use. The Company has determined that technological feasibility for its product candidates is reached when the requisite regulatory approvals are obtained to make the product available for sale. Pursuant to the license agreement with Neuren, the Company has capitalized a t otal of $ 138.8 million as intangible assets following the FDA approval and sale of DAYBUE and sale of PRV, as disclosed in Note 9. The intangible assets are amortized on a straight-line basis over the estimated useful life of the licensed patents through early 2036. The Company recorded total amortization expense related to these intangible assets of $ 15.0 million and $ 4.1 million for the years ended December 31, 2024 and 2023, respectively. As of December 31, 2024, estimated future amortization expense related to the Company’s intangible assets was $ 10.9 million for each subsequent year. Royalties incurred in connection with the Company’s license agreement with Neuren, as disclosed in Note 9, are expensed to cost of product sales as revenue from product sales is recognized . Intangible Assets Finite-lived intangible assets are recorded at cost, net of accumulated amortization, and, if applicable, impairment charges. Amortization of finite-lived intangible assets is recorded over the assets’ estimated useful lives on a straight-line basis or based on the pattern in which economic benefits are consumed, if reliably determinable. We review our finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If such intangible assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of intangible the assets exceeds the estimated fair value of the intangible assets. No impairment loss was recorded on intangible assets during the years ended December 31, 2024 or 2023 . Acquisitions The Company accounts for acquisitions of an asset or group of similar identifiable assets that do not meet the definition of a business as asset acquisition using the cost accumulation method, whereby the cost of the acquisition, including certain transaction costs, is allocated to the assets acquired on the basis of their relative fair values. No goodwill is recognized in an asset acquisition. Intangible assets acquired in an asset acquisition for use in research and development activities which have no alternative future use are expensed as in-process research and development on the acquisition date. Intangible assets acquired for use in research and development activities which have an alternative future use are capitalized as in-process research and development. Future costs to develop these assets are recorded to research and development expense as they are incurred. Contingent milestone payments associated with asset acquisitions are recognized when probable and estimable. These amounts are expensed to research and development if there is no alternative future use associated with the asset, or capitalized as an intangible asset if alternative future use of the asset exists. Advertising Expense Advertising costs are expensed when services are performed or goods are delivered. The Company incurred $ 21.1 million, $ 9.4 million and $ 5.5 mil lion in advertising costs during the years ended December 31, 2024, 2023 and 2022 , respectively and $ 1.3 million of advertising costs were capitalized as prepaid expenses at December 31, 2024. No advertising costs were capitalized as prepaid expenses at December 31, 2023 or 2022. Revenue Recognition The Company operates in one business segment. Results of its operations are reported on a consolidated basis for purposes of s egment reporting, consistent with internal management reporting. Revenues consist of net product sales to customers, all of which are sales in the U.S. Revenues by product are as follows (in thousands): Years Ended December 31, 2024 2023 2022 NUPLAZID $ 609,385 $ 549,248 $ 517,235 DAYBUE 348,412 177,189 — Product sales, net $ 957,797 $ 726,437 $ 517,235 Product Sales, Net The Company accounts for contracts with its customers in accordance with Revenue from Contracts with Customers (Topic 606) . The Company recognizes revenue when its customer obtains control of promised goods or services which is generally upon delivery. Revenues reflect the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of Topic 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of Topic 606, the Company assesses the goods or services promised within each contract, determines those that are performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Payment terms differ by customer, but typically range from 31 to 35 days from the date of shipment. Revenue for the Company’s product sales has not been adjusted for the effects of a financing component as the Company expects, at contract inception, that the period between when the Company transfers control of the product and when the Company receives payment will be one year or less. The Company’s product sales, net consist of U.S. sales of NUPLAZID and DAYBUE. NUPLAZID was approved by the FDA in April 2016 and the Company commenced shipments of NUPLAZID to SPs and SDs in late May 2016. SPs dispense product to a patient based on the fulfillment of a prescription and SDs sell product to government facilities, long-term care pharmacies, or in-patient hospital pharmacies. DAYBUE was approved by the FDA in March 2023 and the Company commenced shipments of DAYBUE to a single wholesale distributor in April 2023. Product shipping and handling costs are included in cost of product sales. The Company recognizes revenue from product sales at the net sales price (the “transaction price”) which includes estimates of variable consideration for which reserves for sales discounts and allowance are established and reflects each of these as either a reduction to the related account receivable or as an accrued liability, depending on how the amount payable is settled. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which the Company is entitled based on the terms of the contract. The amount of variable consideration that is included in the transaction price may be constrained, and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results in the future vary from estimates, the Company may need to adjust its estimates, which would affect net revenue in the period of adjustment. The following are the Company’s significant categories of sales discounts and allowances: Distribution Fees : Distribution fees include distribution service fees paid to the SPs, SDs and wholesale distributor based on a contractually fixed percentage of the wholesale acquisition cost (WAC), fees for data, and prompt payment discounts. Distribution fees are recorded as an offset to revenue based on contractual terms at the time revenue from the sale is recognized. Rebates : Allowances for rebates include mandated discounts under the Medicaid Drug Rebate Program and the Medicare Part D prescription drug benefit. Rebates are amounts owed after the final dispensing of the product to a benefit plan participant and are based upon contractual agreements with, or statutory requirements pertaining to, Medicaid and Medicare benefit providers. The allowance for rebates is based on statutory discount rates, estimated payor mix, and expected utilization. The Company’s estimates for expected utilization of rebates are based on historical data received from the SPs, SDs and single wholesale distributor since product launch. Rebates are generally invoiced and paid in arrears so that the accrual balance consists of an estimate of the amount expected to be incurred for the current quarter’s activity, plus an accrual balance for prior quarters’ unpaid rebates still estimated to be incurred. Allowances for rebates also include amounts due under the Inflation Reduction act of 2022 for Medicare Part D unit sales with applicable period AMP increases that outpace inflation over the benchmark period. The applicable period will be twelve months on October 1 of each year, with the initial applicable period beginning on October 1, 2022. The benchmark period AMP price is January 1, 2021 through September 30, 2021 for NUPLAZID and January 1, 2024 through December 31, 2024 for DAYBUE. The Company’s estimates are based Medicare Part D sales as a percentage of gross sales and the rate AMP for the current period will be in excess the benchmark period. Chargebacks : Chargebacks are discounts and fees that relate to contracts with government and other entities purchasing from the SDs at a discounted price. The SDs charge back to the Company the difference between the price initially paid by the SDs and the discounted price paid to the SDs by these entities. The Company also incurs group purchasing organization fees for transactions through certain purchasing organizations. The Company estimates sales with these entities and accrues for anticipated chargebacks and organization fees, based on the applicable contractual terms. Co-Payment Assistance : The Company offers co-payment assistance to commercially insured patients meeting certain eligibility requirements. Co-payment assistance is accrued for based on actual program participation and estimates of program redemption using data provided by third-party administrators. Product Returns : Consistent with industry practice, the Company offers the SPs and SDs limited product return rights for damages, shipment errors, and expiring product; provided that the return is within a specified period around the product expiration date as set forth in the applicable individual distribution agreement. The Company does not allow product returns for product that has been dispensed to a patient. As the Company receives inventory reports from the SPs and SDs and has the ability to control the amount of product that is sold to the SPs and SDs, it is able to make a reasonable estimate of future potential product returns based on this on-hand channel inventory data and sell-through data obtained from the SPs and SDs. In arriving at its estimate for product returns, the Company also considers historical product returns, the underlying product demand, and industry data specific to the specialty pharmaceutical distribution industry. Research and Development Expenses Research and development expenses are charged to operations as incurred. Research and development expenses include costs associated with services provided by contract organizations for preclinical development, pre-commercialization manufacturing expenses, and clinical trials, salaries and related personnel expenses including stock-based compensation expense, and facilities and equipment expenses. The upfront consideration and transaction costs associated with acquired in-process research and development are also included in the research and development expenses. The Company accrues for costs incurred as the services are being provided by monitoring the status of the trial or services provided and the invoices received from its external service providers. When the Company makes payments in advance of services being provided, it records those amounts as prepaid expenses on its consolidated balance sheets and expense them as the services are rendered. In the case of clinical trials, a portion of the estimated cost normally relates to the projected cost to treat a patient in the trials, and this cost is recognized based on the number of patients enrolled in the trial. Other indirect costs are generally recognized on a straight-line basis over the estimated period of the study. As actual costs become known, the Company adjusts its accruals accordingly. Concentration Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, principally consist of cash, cash equivalents, investment securities, accounts receivable, and restricted cash. The Company invests its excess cash primarily in money market funds, U.S. treasury notes, and high quality, marketable debt instruments of corporations and government sponsored enterprises in accordance with the Company’s investment policy. The Company’s investment policy defines allowable investments and establishes guidelines relating to credit quality, diversification, and maturities of its investments to preserve principal and maintain liquidity. All investment securities have a credit rating of at least Aa3/AA- or better, or P-1/A-1 or better, as determined by Moody’s Investors Service or Standard & Poor’s. Further, the Company specifies credit quality standards for its customers that are designed to limit the Company’s credit exposure to any single party. The Company does not currently have any of its own manufacturing facilities, and therefore it depends on an outsourced manufacturing strategy for the production of NUPLAZID and DAYBUE for commercial use and for the production of its product candidates for clinical trials. For the production of NUPLAZID, the Company has contracts in place with two third-party manufacturers of commercial drug product and one third-party manufacturer of drug substance that is approved for the production of NUPLAZID API. For the production of DAYBUE, the Company has contracts in place with two third-party manufacturers of commercial drug product and two third-party manufacturers of drug substance that is approved for the production of DAYBUE API. Although there are potential sources of supply other than the Company’s existing suppliers, any new supplier would be required to qualify under applicable regulatory requirements. The Company has entered into agreements for the distribution of NUPLAZID with a limited number of SPs and SDs, and all of the Company’s product sales of NUPLAZID are to these customers. The Company has also entered into agreements for the distribution of DAYBUE with a single wholesale distributor, and all of the Company’s product sales of DAYBUE and accounts receivable balance at December 31, 2024 are related to this customer. The following table summarizes customers that represent 10% or greater of our consolidated total gross revenues: Years Ended December 31, 2024 2023 2022 Customer A 34 % 23 % * Customer B 14 % 17 % 25 % Customer C 13 % 15 % 17 % Customer D 12 % 14 % 21 % Customer E 10 % 10 % 11 % __________________________________________ * Represents less than 10 % and/or not a customer in the applicable year The following table summarizes customers with amounts due that represent 10% or greater of our consolidated accounts receivable balance: As of December 31, 2024 2023 Customer A 42 % 33 % Customer B 13 % 14 % Customer C 14 % 12 % Customer D 12 % 14 % Customer E * 10 % __________________________________________ * Represents less than 10 % and/or not a customer in the applicable year Stock-Based Compensation We measure stock-based compensation expense for equity-classified awards, principally related to stock options, restricted stock units (RSUs), PSUs and stock purchase rights under our employee stock purchase plan (ESPP) based on the estimated fair value of the award on the date of grant. The fair value of each employee stock option and each employee stock purchase right granted is estimated on the grant date under the fair value method using the Black-Scholes valuation model. The estimated fair value of each stock option and purchase right is then expensed on a straight-line basis over the requisite service period, which is generally the vesting period. The following weighted-average assumptions were used during these periods: Years Ended December 31, 2024 2023 2022 Stock Options: Expected volatility 62 % 66 % 68 % Risk-free interest rate 4.1 % 3.9 % 2.9 % Expected dividend yield 0 % 0 % 0 % Expected life of options in years 5.5 5.4 5.4 Years Ended December 31, 2024 2023 2022 Employee Stock Purchase Plan: Expected volatility 46 %- 63 % 40 %- 67 % 62 %- 82 % Risk-free interest rate 4.3 %- 5.3 % 4.0 %- 5.3 % 1.5 %- 4.6 % Expected dividend yield 0 % 0 % 0 % Expected life in years 0.5 - 2.0 0.5 - 2.0 0.5 - 2.0 Expected Volatility. The Company considers its historical volatility and implied volatility when determining the expected volatility. Risk-Free Interest Rate. The Company determines its risk-free interest rate assumption based on the U.S. Treasury yield for obligations with contractual terms similar to the expected term of the stock option or purchase right being valued. Expected Dividend Yield. The Company has never paid any dividends and currently has no plans to do so. Expected Life. In determining the expected life for stock options, the Company considers, among other factors, its historical exercise experience to date as well as the mean time remaining to full vesting of all outstanding options and the mean time remaining to the end of the contractual term of all outstanding options. The estimated life for the Company’s employee stock purchase rights is based upon the terms of each offering period. Forfeitures. The Company recognizes forfeitures as they occur. The fair value of RSUs is estimated based on the closing market price of the Company’s common stock on the date of grant. RSUs generally vest over a four-year period. Certain RSUs also have an accelerated vesting clause based on specified market condition target and continued employment through a minimum vesting period. The fair value of RSUs expected to vest are recognized and amortized on a straight-line basis over the requisite service period, which is generally the vesting period. For those RSUs requiring satisfaction of both market and service conditions, the requisite service period is the longest of the explicit, implicit and derived service periods. Through 2023, the Company granted PSUs that vest upon the achievement of certain pre-defined company-specific performance-based criteria. Expense related to these PSUs is recognized ratably over the expected performance period once the pre-defined performance-based criteria for vesting becomes probable and can vest up to 200 percent of the target number of shares granted. The fair value of these PSUs is estimated based on the closing market price of the Company’s common stock on the date of grant. Beginning in 2024, the structure of the PSU design was revised with a rTSR approach such that awards are earned for the Company’s rTSR performance over three-year measurement periods relative to a peer group of companies and the actual numbers of PSUs that will vest at the end of the performance period may be anywhere from zero to 150 percent of the target number of shares granted. The fair value of these PSUs is estimated using a Monte Carlo model because the performance target is based on a market condition. Expense related to these PSUs is recognized ratably over the three-year measurement period. In connection with the departure of the former CEO, in September 2024 the Company incurred approximately $ 10.7 million in stock-based compensation expense as a result of accelerated equity award vesting and stock modifications under the former CEO’s severance plan. The table below summarizes the total stock-based compensation expense included in the Company’s consolidated statements of operations for the periods presented (in thousands): Years Ended December 31, 2024 2023 2022 Cost of product sales $ 1,319 $ 1,007 $ 1,106 Research and development 14,100 17,408 22,580 Sales, general and administrative 51,630 48,006 44,515 $ 67,049 $ 66,421 $ 68,201 Segment The Company uses “the management approach” in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company’s Chief Operating Decision Maker (CODM) for making operating decisions and assessing performance as the source for determining the Company’s reportable segments. The Company determines and presents operating segments based on the information that is internally provided to the CEO who is considered the Company’s CODM, in accordance with ASC 280, Segment Reporting . The Company has determined that it operates as a single business segment, which is the development and commercialization of innovative medicines . Refer to Note 11 – Segment Reporting for further information related to the segment. Income Taxes Current income tax expense or benefit represents the amount of income taxes expected to be payable or refundable for the current year. A deferred income tax asset or liability is computed for the expected future impact of differences between the financial reporting and income tax bases of assets and liabilities and for the expected future tax benefit to be derived from tax credits and loss carryforwards. Deferred income tax expense or benefit represents the net change during the year in the deferred income tax asset or liability. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company recognizes the impact of a tax position in the financial statements only if that position is more likely than not to be sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected in income tax expense. Earning (Net Loss) Per Share Basic earnings (net loss) per share is calculated by dividing the net income (loss) by the weighted average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of common shares and common stock equivalents outstanding for the period determined using the treasury stock method. For purposes of diluted earnings (net loss) per share calculation, equity awards and employee stock purchase plan rights are considered to be common stock equivalents. Years Ended December 31, 2024 2023 2022 Net income (loss) - basic and diluted $ 226,451 $ ( 61,286 ) $ ( 215,975 ) Weighted average shares outstanding: Basic 165,717 163,819 161,683 Effect of potentially dilutive common shares from: Equity awards 576 — — Employee stock purchase plan rights 69 — — Diluted 166,362 163,819 161,683 Earnings (net loss) per share: Basic $ 1.37 $ ( 0.37 ) $ ( 1.34 ) Diluted $ 1.36 $ ( 0.37 ) $ ( 1.34 ) Potentially dilutive shares excluded from per share amounts as their effect 18,233 21,264 21,185 Recently Issued Accounting Standards In November 2023, the FASB issued Accounting Standards Update No. 2023-07, Segment Reporting - Improvements to Reportable Segment Disclosures .
