3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include all adjustments necessary for the fair presentation of the Company’s financial position for the periods presented. All intercompany accounts and transactions have been eliminated.

Significant Risks and Uncertainties

The Company’s operations are subject to a number of factors that can affect its operating results and financial condition. Such factors include, but are not limited to, the results of clinical testing and trial activities of the Company’s product candidates; the Company’s ability to obtain regulatory approval to market its products; competition from products manufactured and sold or being developed by other companies; the price of, and demand for, the Company’s products, if approved; the Company’s ability to negotiate favorable licensing or other manufacturing and marketing agreements for its product candidates; and the Company’s ability to raise capital.

The Company currently has one commercially approved product, WAKIX, and there can be no assurance that the Company’s research and development efforts will result in successfully commercialized products in addition to WAKIX. Developing and commercializing a product requires significant time and capital and is subject to regulatory review and approval as well as competition from other biotechnology and pharmaceutical companies. The Company operates in an environment of rapid change and is dependent upon the continued services of its employees and consultants and obtaining and protecting intellectual property.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in the consolidated financial statements, including the notes thereto, and elsewhere in this report. Actual results may differ significantly from estimates, which include rebates due pursuant to commercial and government contracts, accrued research and development expenses, stock-based compensation expense and income taxes.

Operating Segments

The Company holds all its tangible assets, conducts its operations, and generates its revenues in the U.S. Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Makers in deciding how to allocate resources to an individual segment and in assessing performance. The Company has determined it operates in a single operating segment and has one reportable segment.

Fair Value of Financial Instruments

The Company’s consolidated financial statements include cash, cash equivalents, accounts payable, and accrued liabilities, all of which are short term in nature and, accordingly, approximate fair value. Additionally, prior to the IPO, the Company’s consolidated financial statements included a warrant liability that was carried at fair value and was re-measured at each balance sheet date until it would be exercised or expired. In connection with the IPO, the Warrants were re-evaluated under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity, and reclassified to equity. See Note 16 for a further discussion of the warrants.

It is the Company’s policy to measure non-financial assets and liabilities at fair value on a nonrecurring basis. These non-financial assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (such as evidence of impairment), which, if material, are disclosed in the accompanying footnotes.

The Company measures certain assets and liabilities at fair value based on the fair value hierarchy that prioritizes inputs to valuation techniques used to measure fair value into three levels based on the source of inputs as follows:

Level 1—Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2—Valuations based on observable inputs and quoted prices in active markets for similar assets and liabilities.

Level 3—Valuations based on unobservable inputs and models that are supported by little or no market activity.

Money market funds are classified as Level 1 fair value instruments. Investments in available-for-sale debt securities are classified as Level 2 and carried at fair value, which we estimate utilizing a third-party pricing service. The pricing service utilizes industry standard valuation models whereby all significant inputs, including benchmark yields, reported trades, broker/dealer quotes, issuer spreads, bids, offers, or other market-related data, are observable. We validate valuations obtained from third-party services by obtaining market values from other pricing sources. The Company did not classify any assets or liabilities as Level 3 as of December 31, 2022 or December 31, 2021.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents and restricted cash consist of cash and, if applicable, highly liquid investments with an original maturity of three months or less when purchased, including investments in Money Market Funds and debt securities that approximate fair value. The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the balance sheet that equal the amount reflected in the statements of cash flows.

	As of
	December 31,		December 31,
	2022		2021
Cash and cash equivalents	$	243,784	$	234,309
Restricted cash		750		750
Total cash, cash equivalents, and restricted cash shown in the statements of cash flows	$	244,534	$	235,059

Restricted cash includes amounts required to be held as a security deposit in the form of letters of credit for the Company’s credit card program and the fleet program.

Investments

The Company’s investments consist of debt securities that are classified as available-for-sale. Short-term and long-term investments are carried at fair value and unrealized gains and losses are recorded as a component of accumulated comprehensive income in stockholders’ equity. The amortization of premiums and accretion of discounts adjust the carrying value of investments and are recorded in interest expense, net, on the unaudited condensed consolidated statements of operations and comprehensive income. Interest income and realized gains and losses, if any, are also recorded in interest expense, net, on the unaudited condensed consolidated statement of operations and comprehensive income. Realized gains and losses that result from the sale of investments are determined on a specific identification basis.

At each reporting period, the Company reviews any unrealized losses position to determine if the decline in the fair value of the underlying investments is a result of credit losses or other factors. If the assessment indicates that a credit loss exists, any impairment is recognized as an allowance for credit losses in our consolidated statement of operations.

Concentrations of Risk

Substantially all of the Company’s cash and money market funds are held in two financial institutions. Due to their size, the Company believes these financial institutions represent minimal credit risk. Deposits may exceed the amount of insurance provided on such deposits by the Federal Deposit Insurance Corporation for U.S. institutions. The Company has not experienced any losses on its deposits of cash and cash equivalents. The Company believes that it is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.

The Company is also subject to credit risk from its trade receivables related to its product sales. The Company extends credit to specialty pharmaceutical distribution companies within the United States. Customer creditworthiness is monitored and collateral is not required. Historically, the Company has not experienced credit losses on its accounts receivable. The Company monitors its exposure within accounts receivable and would record a reserve against uncollectible accounts receivable if necessary. As of December 31, 2022, three customers accounted for 100% of gross accounts receivable, Caremark LLC (“CVS Caremark”), which accounted for 41% of gross accounts receivable; Accredo Health Group, Inc. (“Accredo”), which accounted for 35% of gross accounts receivable; and PANTHERx Specialty Pharmacy LLC (“Pantherx”), which accounted for 24% of gross accounts receivable. As of December 31, 2021, three customers accounted for 100% of gross accounts receivable; Accredo, which accounted for 40% of gross accounts receivable, Pantherx, which accounted for 31% of gross accounts receivable and CVS Caremark, which accounted for 29% of gross accounts receivable.

For the year ended December 31, 2022, three customers accounted for 100% of gross product revenues; CVS Caremark accounted for 42% of gross product revenues; Pantherx accounted for 29% of gross product revenues; and Accredo accounted for 29% of gross product revenues. For the year ended December 31, 2021, three customers accounted for 100% of gross product revenues; CVS Caremark accounted for 36% of gross product revenues; Pantherx accounted for 35% of gross product revenues; and Accredo accounted for 29% of gross product revenues. For the year ended December 31, 2020, three customers accounted for 100% of gross product revenues; CVS Caremark accounted for 40% of gross product revenues; Pantherx accounted for 33% of gross products revenues; and Accredo accounted for 27% of gross product revenues.

The Company depends on a single source supplier for each of its product and active pharmaceutical ingredient.

Inventory

Inventory is valued at the lower of cost or net realizable value. Cost is determined using the specific identification method for all inventory. Our policy is to write down inventory that has become obsolete, that has a cost basis in excess of its expected net realizable value and/or that we have quantities in excess of expected future demand. The estimate of excess quantities is subjective and primarily dependent on our estimates of future demand. If our estimate of future demand changes, we consider the impact on the reserve for excess inventory and adjust the reserve as required. Inventory reserves are recorded as a component of cost of product sales in our consolidated statement of operations.

We may capitalize inventory costs associated with products prior to regulatory approval when future commercialization is probable. otherwise, such costs are expensed as research and development. The determination to capitalize inventory costs is based on various factors, including status and expectations of the regulatory approval process, any known safety or efficacy concerns, potential labeling restrictions, and any other impediments to obtaining regulatory approval.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally between three and ten years. Leasehold improvements are depreciated using the straight-line method over the shorter of the estimated useful life of the asset or the term of the lease. The Company’s leasehold improvements primarily relate to its corporate headquarters in Plymouth Meeting, PA, and are generally being depreciated through the end of the lease term in May 2024. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the balance sheet and any resulting gain or loss is reflected in the consolidated statement of operations and comprehensive income (loss) in the period realized.

Intangible Assets

Intangible assets with finite useful lives consist primarily of purchased developed technology and are amortized on a straight-line basis over their estimated useful lives. The estimated useful lives associated with finite-lived intangible assets are consistent with the estimated lives of the associated products and may be modified when circumstances warrant. Such assets are reviewed for impairment when events or circumstances indicate that the carrying value of an asset may not be recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of an asset and its eventual disposition are less than its carrying amount. The amount of any impairment is measured as the difference between the carrying amount and the fair value of the impaired asset.

Revenue Recognition

We account for contracts with our customers in accordance with ASC 606, Revenue from Contracts with Customers (ASC 606), or ASC 606. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the entity 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 entity satisfies a performance obligation. We only apply the five-step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services it transfers to the customer. The amount of variable consideration which 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 under contracts will not occur in a future period. Our analyses contemplate the application of the constraint in accordance with ASC 606. Actual amounts of consideration ultimately received may differ from our estimates. If actual results in the future vary from our estimates, we will adjust these estimates, which would affect net product revenue and earnings in the period such variances become known.

We have determined that the delivery of our product to our customer constitutes a single performance obligation as there are no other promises to deliver goods or services in contracts with our customers. Shipping and handling activities are considered to be fulfilment activities and are not considered to be a separate performance obligation. The payment terms with our customers do not exceed one year and therefore, no amount of consideration has been allocated as a financing component. Taxes collected related to product sales are remitted to governmental authorities and are excluded from revenue.

Product Sales, Net

We recognize revenue on sales of WAKIX when the customer obtains control of the product, which occurs at a point in time, typically upon delivery. Product revenues are recorded at the product’s list price, net of applicable reserves for variable consideration that are offered within contracts between us and our customers, payors, and other indirect customers relating to the sale of WAKIX. Components of variable consideration include government (as detailed below) and commercial contracts, commercial co-payment assistance program transactions, and distribution service fees. These deductions are based on the amounts earned, or to be claimed on the related sales, and are classified as a current liability or reduction of receivables.

Government Contracts

We have entered into contracts (i) to participate in the Medicaid Drug Rebate Program and the Medicare Part D program, and (ii) to sell to the U.S. Department of Veterans Affairs, 340b entities and other government agencies, or government payors, so that WAKIX will be eligible for purchase by, in partial or full reimbursement from, such government payors. We record reserves for rebates due pursuant to these contracts as a reduction of revenue in the same period in which the revenue is recognized. The liability for government rebates is included in accrued expenses in our consolidated balance sheet.

We estimate rebates due pursuant to government contracts based upon our historical payment and payor mix trends, information obtained from third parties estimating current payor mix, the government-mandated discounts applicable to government-funded programs, as well as information obtained from our customers. The liability for these government rebates consists of estimates of claims for WAKIX dispensed in the current period, plus an estimate for product which has shipped and has been recognized as revenue but remains in the distribution channel at the end of a reporting period.

Cost of Product Sold

Cost of product sold includes manufacturing and distribution costs, the cost of drug substance, FDA program fees, royalties due to third parties on net product sales, freight, shipping, handling, storage costs, and salaries of employees involved with production.

Research and Development Expenses

Research and development costs are expensed as incurred. Liabilities due to third parties in connection with research and development collaborations prior to regulatory approval are expensed as incurred.

Upfront payments and pre-FDA approval milestone payments made for licensing of technology are expensed as research and development in the period in which they are incurred. Advance payments for goods and services to be received in the future for use in research and development activities are recorded as prepaid expenses. The prepaid amounts are expensed as the related goods are delivered or the services are performed.

Advertising Expenses

We expensed the costs of advertising, including promotional expenses, as incurred. Advertising expenses were   $22,428, $19,558 and $13,301 for the years ended December 31, 2022, 2021 and 2020, respectively.

Stock-Based Compensation

The Company recognizes compensation expense relating to stock-based payment transactions in operating results using a fair value measurement method, in accordance with FASB ASC 718, Compensation-Stock Compensation. ASC 718 requires all stock-based payments to employees to be recognized in operating results as compensation expense based on fair value over the requisite service period of the awards. The vesting periods have a time-based provision consisting of three to five years and expire no more than 10 years after the date of grant. Upon a change of control, certain unvested awards will immediately vest. The Company determines the fair value of stock-based awards on their grant date using the Black-Scholes option-pricing model, which uses both historical and current market data to estimate fair value. The method incorporates various assumptions, such as the risk-free interest rate, expected volatility, expected dividend yield, and expected life of the options. The Company also had nonemployee stock awards subject to a performance condition that are recognized based on probable outcome of achieving future events.

Basic and Diluted Net Income (Loss) per Share

Basic net income (loss) per share is determined using the weighted average number of shares of common stock outstanding during each period. Diluted net income per share includes the effect, if any, from the potential exercise or conversion of securities, such as convertible preferred stock and stock options, which would result in the issuance of incremental shares of common stock. The computation of diluted net loss per shares does not include the conversion of securities that would have an anti-dilutive effect. The basic and diluted computations of net loss per share for the Company are the same because the effects of the Company’s convertible securities would be anti-dilutive (see Note 17 for further detail).

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Deferred tax assets may be reduced by a valuation allowance if, based on all available evidence, it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Management judgment is required in determining the period in which a reversal of a valuation allowance should occur. The Company is required to consider all available evidence, both positive and negative, such as historical levels of income and future forecasts of taxable income among other items, in determining whether a full or partial release of its valuation allowance is required. During the year ended December 31, 2022, in part because in the current year we achieved three years of cumulative pretax income, which is a positive indication of the Company’s ability to generate sufficient future taxable income, the Company determined that there was sufficient positive evidence to conclude that it is more likely than not that additional deferred taxes are realizable and, therefore, released the valuation allowance accordingly. Our accounting for deferred tax consequences represents the

best estimate of those future events. The Company presents deferred income taxes on the Consolidated Balance Sheet on a jurisdictional basis as either a net noncurrent asset or liability.

The Company recognizes the effect of income tax positions only if those positions are more likely than not sustainable, based solely on its technical merits and consideration of the relevant taxing authority’s widely understood administrative practices and precedents. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which a change in judgment occurs. At December 31, 2022 and 2021, the Company did not have any unrecognized uncertain tax positions. The Company’s policy is to include any interest and penalties as a component of income tax expense.

Recently Issued Accounting Pronouncements

ASU 2020-04, Reference Rate Reform (Topic 848). In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848), which provides guidance related to reference rate reform. The pronouncement provides temporary optional expedients and exceptions to the current guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates. The guidance was effective upon issuance and could initially be applied to applicable contract modifications through December 31, 2022, which was extended to December 31, 2024 upon the FASB issuing ASU No. 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. The Company is currently evaluating the impact of the transition from LIBOR to alternative reference rates but does not expect a significant impact to its consolidated financial statements.
