Nature of Operations and Basis of Presentation

1. Nature of Operations and Basis of Presentation

Organization and Principal Activities

Scilex Holding Company (“Scilex” and together with its wholly owned subsidiaries, the “Company”) is the successor entity to Vickers Vantage Corp. I (“Vickers”). Vickers was formed on February 21, 2020 as a Cayman Islands exempted company for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities. Scilex was originally formed in 2019 and is a majority-owned subsidiary of Sorrento Therapeutics, Inc. (“Sorrento”). Scilex has two wholly owned subsidiaries, Scilex Pharmaceuticals Inc. (“Scilex Pharma”) and Semnur Pharmaceuticals, Inc. (“Semnur”). The Company is a commercial biopharmaceutical company focused on acquiring, developing and commercializing non-opioid management products for the treatment of acute and chronic pain. The Company launched its first commercial product in October 2018, ZTlido (lidocaine topical system) 1.8% (“ZTlido”), a prescription lidocaine topical system that is designed with novel technology to address the limitations of current prescription lidocaine therapies by providing significantly improved adhesion and continuous pain relief throughout the 12-hour administration period. The Company in-licensed the exclusive right to commercialize GLOPERBA (colchicine USP) oral solution, an FDA-approved prophylactic treatment for painful gout flares in adults, in the U.S. (see Note 2). The Company is planning to commercialize GLOPERBA in 2023. The Company is currently developing three product candidates, SP-102 (10 mg, dexamethasone sodium phosphate viscous gel), a Phase 3, novel, viscous gel formulation of a widely used corticosteroid for epidural injections to treat lumbosacral radicular pain, or sciatica (“SP-102” or “SEMDEXA”), SP-103 (lidocaine topical system) 5.4% (“SP-103”), for the treatment of acute low back pain, and SP-104 (4.5 mg, low-dose naltrexone hydrochloride delayed-release capsules) (“SP-104”), a novel formulation for the treatment of fibromyalgia. Since inception, the Company has devoted substantially all of its efforts to the development of SP-102, SP-103, SP-104, and the commercialization of ZTlido.

The Business Combination

On March 17, 2022, Scilex entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Vickers and Vantage Merger Sub, Inc., a wholly-owned subsidiary of Vickers (“Vickers Merger Sub”). Pursuant to the terms of the Merger Agreement, Vickers Merger Sub merged with and into Scilex, Inc. (f/k/a Scilex Holding Company and now a wholly owned subsidiary of Scilex) (“Legacy Scilex"), with Legacy Scilex surviving the merger and becoming a wholly-owned subsidiary of Vickers (collectively, the “Business Combination”).

On November 10, 2022, Vickers consummated the Business Combination pursuant to the terms of the Merger Agreement. Vickers acquired all of the outstanding equity interests of Legacy Scilex. As a result of the Business Combination, Scilex received net proceeds of approximately $3.4 million. Additionally, all existing related party indebtedness between Legacy Scilex and Sorrento totaling $290.6 million was converted into equity interests in Vickers in connection with the consummation of the Business Combination and pursuant to the terms of the Debt Exchange Agreement (see Note 12). The Company, as the successor entity of Vickers, will operate as “Scilex Holding Company” and was listed on the Nasdaq Capital Market under the new ticker symbol “SCLX” on November 11, 2022.

At the closing of the Business Combination, 197,566,338 and 25,151,428 shares of Legacy Scilex Common Stock (“Legacy Scilex Common Stock”) and Legacy Scilex stock options, respectively, were converted to 133,060,534

shares of Common Stock (“Common Stock”) as part of the consideration using the 0.673498:1 ratio of the Company Common Stock to Legacy Scilex Common Stock (the “Common Stock Exchange Ratio”) and 16,939,436 shares of Common Stock were reserved for Legacy Scilex optionholders. Pursuant to the terms of the Debt Exchange Agreement (see Note 12), $290.6 million was converted to 29,057,097 shares of Preferred Stock (“Preferred Stock”) and 2,905,710 shares of Common Stock. In addition, pursuant to the terms of the debt agreement entered between the Vickers Venture Fund VI Pte Ltd, Vickers Venture Fund VI (Plan) Pte Ltd (“Sponsors”) and Vickers (“Vickers Debt Agreement”), the aggregate amount of loans that the Sponsors funded Vickers to finance the transaction costs (“Working Capital Loans”) at the closing of the Business Combination of $5,330,557 was converted to 533,057 shares of Common Stock.

The Business Combination was accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Vickers was treated as the “acquired” company for accounting purposes and the Business Combination was treated as the equivalent of the Company issuing stock for the net assets of Vickers, accompanied by a recapitalization. Upon the closing of the Business Combination, the net assets of Vickers were recorded at historical cost, with no goodwill or other intangible assets recorded.

The Company’s legal, accounting and other fees directly attributable to the Business Combination were initially capitalized within prepaid expenses and other current assets on the consolidated balance sheets, of which $9.1 million has been offset against the equity proceeds in the Business Combination and $0.4 million was attributed to the liability-classified Private Warrants and, as such, were expensed upon the closing of the Business Combination.

Basis of Presentation

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include all adjustments necessary for the fair presentation of the Company’s financial position for the periods presented.

The accompanying consolidated financial statements include the accounts of the Company as well as its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of these 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 and disclosure of contingent assets and liabilities at the date of these consolidated financial statements and the reported amounts of expenses during the reporting period. Management believes that these estimates are reasonable; however, actual results may differ from these estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. The Company minimizes its credit risk associated with cash and cash equivalents by periodically evaluating the credit quality of its primary financial institution. Although the balance at times may exceed federally-insured limits, the Company has not experienced any losses on such accounts.

Fair Value of Financial Instruments

The Company follows accounting guidance on fair value measurements for financial instruments measured on a recurring basis, as well as for certain assets and liabilities that are initially recorded at their estimated fair values. Fair value is defined as the exit price, or the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses the following three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs to value its financial instruments:

•

Level 1: Observable inputs such as unadjusted quoted prices in active markets for identical instruments.

•

Level 2: Quoted prices for similar instruments that are directly or indirectly observable in the marketplace.

•

Level 3: Significant unobservable inputs which are supported by little or no market activity and that are financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation.

Financial instruments measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires it to make judgments and consider factors specific to the asset or liability. The use of different assumptions and/or estimation methodologies may have a material effect on estimated fair values. Accordingly, the fair value estimates disclosed or initial amounts recorded may not be indicative of the amount that the Company or holders of the instruments could realize in a current market exchange.

As of December 31, 2022 and 2021, the carrying amount of cash equivalents approximates their fair value based upon quoted market prices. Certain of the Company’s financial instruments are not measured at fair value on a recurring basis, but are recorded at amounts that approximate their fair value due to their liquid or short-term nature, such as cash, prepaid expenses, accounts receivable, and accounts payable.

Accounts Receivable, Net

Accounts receivable are presented net of allowances for expected credit losses and prompt payment discounts. Accounts receivable consists of trade receivables from product sales to customers, which are generally unsecured. Estimated credit losses related to trade accounts receivable are recorded as general and administrative expenses and as an allowance for expected credit losses within accounts receivable, net. The Company reviews reserves and makes adjustments based on historical experience and known collectability issues and disputes. When internal collection efforts on accounts have been exhausted, the accounts are written off by reducing the allowance for expected credit losses.

Inventory

The Company determines inventory cost on a first-in, first-out basis. The Company reduces the carrying value of inventories to a lower of cost or net realizable value for those items that are potentially excess, obsolete or slow- moving. The Company reserves for excess and obsolete inventory based upon historical experience, sales trends, and specific categories of inventory and expiration dates for on-hand inventory. Inventory costs resulting from these adjustments are recognized as cost of sales in the period in which they are incurred. When future commercialization is considered probable and the future economic benefit is expected to be realized, based on management’s judgment, the Company capitalizes pre-launch inventory costs prior to regulatory approval. As of December 31, 2022 and 2021, the Company’s inventory was primarily comprised of finished goods.

Property and Equipment, Net

Property and equipment are carried at cost less accumulated depreciation. Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives of the assets, which are generally five to seven years. Leasehold improvements are amortized over the lesser of their estimated useful lives or the term of the respective lease on a straight-line basis. The cost of repairs and maintenance is expensed as incurred.

Acquisitions

The Company accounts for business combinations using the acquisition method of accounting, which requires that assets acquired, including in-process research and development (“IPR&D”) projects and liabilities assumed be recorded at their fair values as of the acquisition date on the Company`s consolidated balance sheets. Any excess of purchase price over the fair value of net assets acquired is recorded as goodwill. The determination of estimated fair value requires the Company to make significant estimates and assumptions. As a result, the Company may record adjustments to the fair values of assets acquired and liabilities assumed within the measurement period (up to one year from the acquisition date) with the corresponding offset to goodwill. Transaction costs associated with business combinations are expensed as they are incurred.

When the Company determines net assets acquired do not meet the definition of a business combination under the acquisition method of accounting, the transaction is accounted for as an acquisition of assets and, therefore, no goodwill is recorded and contingent consideration such as payments upon achievement of various developmental, regulatory and commercial milestones generally is not recognized at the acquisition date. In an asset acquisition, up-front payments allocated to IPR&D projects at the acquisition date and subsequent milestone payments are charged to expense in the Company`s consolidated statements of operations unless there is an alternative future use.

The Company has acquired and may continue to acquire the rights to develop and commercialize new product candidates. Intangible assets acquired in a business combination that are used for IPR&D activities are considered indefinite-lived until the completion or abandonment of the associated research and development efforts. Upon commercialization of the relevant research and development project, the Company amortizes the acquired IPR&D over its estimated useful life. Capitalized IPR&D is reviewed annually for impairment or more frequently as changes in circumstance or the occurrence of events suggest that the remaining value may not be recoverable.

Goodwill and Other Long-Lived Assets

Goodwill, which has an indefinite life, represents the excess cost over fair value of net assets acquired. Goodwill is reviewed for impairment at least annually during the fourth quarter, or more frequently if events occur indicating the potential for impairment. The Company has one reporting unit. During its goodwill impairment review, the Company may assess qualitative factors to determine whether it is more likely than not that the fair value of its reporting unit is less than its carrying amount, including goodwill. The qualitative factors include, but are not limited to, macroeconomic conditions, industry and market considerations, and the overall financial performance of the Company. If, after assessing the totality of these qualitative factors, the Company determines that it is not more likely than not that the fair value of its reporting unit is less than its carrying amount, then no additional assessment is deemed necessary. Otherwise, the Company performs a quantitative goodwill impairment test. The Company may also elect to bypass the qualitative assessment in a period and elect to proceed to perform the quantitative goodwill impairment test.

The Company evaluates its long-lived and intangible assets with definite lives, such as property and equipment, patent rights, and acquired technology, for impairment by considering competition by products prescribed for the same indication, the likelihood and estimated future entry of non-generic and generic competition with the same or similar indication and other related factors. The factors that drive the estimate of useful life are often uncertain and are reviewed on a periodic basis or when events occur that warrant review. Recoverability is measured by comparison of the assets’ book value to future net undiscounted cash flows that the assets are expected to generate to determine if a write-down to the recoverable amount is appropriate. If such assets are written down, an impairment will be recognized as the amount by which the book value of the asset group exceeds the recoverable amount.

Contingent Consideration

The fair value of contingent consideration liabilities assumed in business combinations is recorded as part of the purchase price consideration of the acquisition, and is determined using a discounted cash flow model or Monte Carlo simulation model. The significant inputs of such models are not observable in the market, such as certain financial metric growth rates, volatility rates, projections associated with applicable milestones, discount rates and the related probabilities and payment structure in the contingent consideration arrangement. Fair value adjustments to contingent consideration liabilities are recorded through operating expenses in the consolidated statement of operations. Other than contingent consideration that is accounted for in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480, Distinguishing Liabilities from Equity, and Topic 815, Derivatives and Hedging, contingent consideration arrangements assumed in an asset acquisition will be measured and accrued when such contingency is resolved.

Public Warrants and Private Placement Warrants

Upon completion of the Business Combination, the Company assumed public and private placement warrants (“Public Warrants” and “Private Warrants”) that were issued by Vickers in connection with its initial public offering (declared effective by the Securities and Exchange Commission (“SEC”) on January 11, 2021) whereby holders of the public and private placement warrants are entitled to acquire ordinary shares of Vickers.

Subsequent to the Business Combination, the Public Warrants were accounted for as equity per FASB ASC Subtopic No. 815-40, Contracts on an Entity’s Own Equity. Warrants classified as equity are recorded at their issuance cost and are not subject to remeasurement at each subsequent balance sheet date.

Subsequent to the Business Combination, the Private Warrants were accounted for as liabilities per ASC Subtopic 815-40. The Private Warrants are not considered indexed to the Company’s stock per ASC Subtopic 815-40 as the fair value calculation applicable upon a cashless exercise of a Private Warrant changes based upon the holder of the instrument, which is not an input to a valuation model for a fixed-for-fixed option contract. Therefore, Private Warrants are recognized as derivative liabilities at their estimated fair value on November 10, 2022, the date of the closing of the Business Combination, and are revalued at each subsequent balance sheet date, with fair value changes recognized in the statement of operations. The Company estimates the value of these warrants using a Black-Scholes option pricing formula.

Debt

The Company may enter financing arrangements, the terms of which involve significant assumptions and estimates. This involves estimating future net product sales, determining interest expense, determining the amortization period of the debt discount, as well as determining the classification between current and long-term portions.

Derivative Liabilities

Derivative liabilities are recorded on the Company’s consolidated balance sheets at their fair value on the date of issuance and are revalued on each balance sheet date until such instruments are exercised or expire, with changes in the fair value between reporting periods recorded as other income or expense.

Research and Development Costs

The Company expenses the cost of research and development as incurred. Research and development expenses are comprised of costs incurred in performing research and development activities, including clinical trial costs, manufacturing costs for both clinical and preclinical materials as well as other contracted services, license fees and other external costs. Nonrefundable advance payments for goods and services that will be used in future research and development activities are expensed when the activity is performed or when the goods have been received, rather than when payment is made, in accordance with FASB ASC Topic 730, Research and Development.

Income Taxes

The provisions of the FASB ASC Topic 740, Income Taxes, addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under ASC Subtopic 740-10, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The Company has determined that it has uncertain tax positions.

The Company accounts for income taxes using the asset and liability method to compute the differences between the tax basis of assets and liabilities and the related financial amounts, using currently enacted tax rates.

The Company has deferred tax assets, which are subject to periodic recoverability assessments. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that more likely than not will be realized. As of December 31, 2022 and 2021, the Company maintained a full valuation allowance against its deferred tax assets.

Leases

The Company determines if an arrangement is a lease at inception. Operating lease right-of-use (“ROU”) assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, it uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and is reduced by lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term in selling, general and administrative expenses.

Revenue Recognition

The Company’s revenue is generated from product sales within the United States. The Company does not incur significant direct costs to obtain contracts with its customers.

Revenue from product sales is fully comprised of sales of ZTlido. The Company’s performance obligation with respect to sales of ZTlido is satisfied at a point in time, when control is transferred upon delivery of product to the customer. The Company considers control to have transferred upon delivery because the customer has legal title to the product,

physical possession of the product has been transferred to the customer, the customer has significant risks and rewards of ownership of the product, and the Company has a present right to payment at that time. Invoicing typically occurs upon shipment and the length of time between invoicing and when payment is due is not significant. The aggregate dollar value of unfulfilled orders as of December 31, 2022 and 2021 were not material.

Revenues from product sales are recorded net of reserves established for commercial and government rebates, fees and chargebacks, wholesaler and distributor fees, sales returns and prompt payment discounts. Such variable consideration is estimated in the period of the sale and is estimated using a most likely amount approach based primarily upon provisions included in the Company’s customer contract, customary industry practices and current government regulations.

Rebates and Chargebacks

Rebates are discounts which the Company pays under either government or private health care programs. Government rebate programs include state Medicaid drug rebate programs, the Medicare coverage gap discount programs and the Tricare programs. Commercial rebate and fee programs relate to contractual agreements with commercial healthcare providers, under which the Company pays rebates and fees for access to and position on that provider’s patient drug formulary. Rebates and chargebacks paid under government programs are generally mandated under law, whereas private rebates and fees are generally contractually negotiated by the Company with commercial healthcare providers. Both types of rebates vary over time. The Company records a reduction to gross product sales at the time the customer takes title to the product based on estimates of expected rebate claims. The Company monitors the sales trends and adjusts for these rebates on a regular basis to reflect the most recent rebate experience and contractual obligations. Reserves for rebates and chargebacks are now separately presented as accrued rebates and fees under current liabilities within the Company’s consolidated balance sheet.

Prompt Payment Discounts

The Company provides its customers with prompt payment discounts which may result in adjustments to the price that is invoiced for the product transferred, in the case that payments are made within a defined period. The prompt payment discount reserve is based on actual gross sales and contractual discount rates. Reserves for prompt payment discounts are included in accounts receivable, net on the consolidated balance sheets.

Service Fees

The Company compensates its customer and others in the distribution chain for wholesaler and distribution services. The Company has determined such services received to date are not distinct from the Company’s sale of products to the customer and, therefore, these payments have been recorded as a reduction of revenue.

Product Returns

The Company is obligated to accept the return of products sold that are expiring within six months, damaged or do not meet certain specifications. The Company may authorize the return of products sold in accordance with the term of its sales contracts, and estimates allowances for such amounts at the time of sale. The Company estimates the amount of its product sales that may be returned by its customer and record this estimate as a reduction of revenue in the period the related product revenue is recognized.

Co-Payment Assistance

Patients who have commercial insurance or pay cash and meet certain eligibility requirements may receive co- payment assistance. The Company accrues for co-payment assistance based on actual program participation and estimates of program redemption using data provided by third-party administrators.

Customer Concentration Risk

Prior to April 2, 2022, sales to the Company's sole distributor represented 100% of net revenue. On April 2, 2022, the Company announced the expansion of its direct distribution network to national and regional wholesalers and pharmacies. The distributor continued to provide traditional third-party logistics functions for the Company. The Company had four customers during the year ended December 31, 2022, which individually generated 10% or more of the Company’s total revenue. These customers accounted for 83% of the Company’s revenue for the year ended December 31, 2022, individually ranging between 19% to 24%. As of December 31, 2022, these customers represented 90% of the Company’s outstanding accounts receivable, individually ranging between 24% to 36%. Additionally, during the fiscal years ended December 31, 2022 and 2021, the Company purchased inventory from its sole supplier, Itochu. This exposes the Company to concentration of customer and supplier risk. The Company monitors the financial condition of its customers, limits its credit exposure by setting credit limits, and has not experienced any credit losses for the years ended December 31, 2022, 2021, and 2020.

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with FASB ASC Topic 718, Compensation – Stock Compensation which establishes accounting for equity instruments exchanged for employee and consulting services. Under such provisions, stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense, under the straight-line method, over the employee’s requisite service period (generally the vesting period of the equity grant) or non-employee’s vesting period. The Company accounts for forfeitures as incurred.

For purposes of determining the inputs used in the calculation of stock-based compensation, the Company determines the expected life assumption for options issued using the simplified method, which is an average of the contractual term of the option and its ordinary vesting period since the Company does not have historic exercise behavior. Then the Company determines an estimate of option volatility based on an assessment of historical volatilities of comparable companies whose share prices are publicly available. The Company uses these estimates as variables in the Black-Scholes option pricing model. Depending upon the number of stock options granted, any fluctuations in these calculations could have a material effect on the results presented in our consolidated statement of operations.

Segments

Operating segments are identified as components of an entity where separate discrete financial information is available for evaluation by the chief operating decision maker in making decisions on how to allocate resources and assessing performance. The Company has determined that its chief operating decision maker is its Chief Executive Officer, as he is responsible for making decisions regarding the allocation of resources and assessing performance as well as for strategic operational decisions. The Company is engaged primarily in the development of non-opioid products focused on pain management based on its platform technologies and all sales are based in the United States. Accordingly, the Company has determined that it operates its business as a single reportable segment.

Net Loss per Share

Under the two-class method, basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share attributable to common stockholders adjusts basic earnings per share for the potentially dilutive impact of stock options and warrants.

As the Company has reported losses for all periods presented, all potentially dilutive securities are antidilutive and accordingly, basic net loss per share equals diluted net loss per share.

Recent Accounting Pronouncements

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an acquirer in a business combination to recognize and measure contract assets and contract liabilities in accordance with ASC Topic 606. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022 and early adoption is permitted. The Company is evaluating the impact the standard will have on its consolidated financial statements.

Liquidity and Going Concern

2. Liquidity and Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. Management has assessed the Company’s ability to continue as a going concern for at least one year after the date the financial statements are issued.

On March 18, 2019, Scilex acquired Semnur and the acquisition was accounted for as an asset acquisition (see Note 3). The Company anticipates the cash needed for the development of Semnur’s primary product candidate in development, SP-102, as well in the development of SP-103, will be in excess of the Company’s cash available within one year after the date these consolidated financial statements are issued. Semnur has no historical revenue and the Company will be responsible for funding all development and commercialization efforts and capital funding needs possibly through private or public equity or debt financings, strategic collaborations or other arrangements.

On May 12, 2022, the Company entered into a Bill of Sale (see Note 3), with Sorrento to acquire rights, title and interest in the SP-104 Assets (see Note 3). SP-104 has not been approved for commercialization and, as such, no revenues have been generated to date by the asset. The Company will be responsible for funding all development and commercialization efforts.

On June 14, 2022, the Company entered into a license and commercialization agreement with Romeg (see Note 3). The transaction was accounted for as an asset acquisition since substantially all the value of the gross assets was concentrated in the single asset, acquired licenses. The Company anticipates incurring costs related to the commercial launch and marketing of GLOPERBA.

On September 12, 2022, Scilex and Scilex Pharma entered into a Debt Exchange Agreement (see Note 12) with Sorrento, pursuant to which all related party indebtedness that remained outstanding as of immediately prior to the closing of the Business Combination was converted into equity interests in the Company.

In September 2022, the Company exercised the Early Paydown Provision (see Note 7) to fully extinguish the Scilex Pharma Notes (see Note 7). In August 2022 and September 2022, the Company made principal payments towards the outstanding Scilex Pharma Notes totaling $41.4 million. Pursuant to Amendment No. 4 (see Note 7), a principal balance of $28.0 million was forgiven by the Scilex Pharma Note Purchasers (see Note 7) upon the Company’s exercise of the Early Paydown Provision. The Company funded the principal payments with cash-on hand and $34.0 million received from Sorrento on September 28, 2022 (see Note 7).

As of December 31, 2022, the Company’s negative working capital was $15.2 million, including cash and cash equivalents of approximately $2.2 million. During the year ended December 31, 2022, the Company had operating losses of $50.6 million and cash flows used for operations of $21.3 million. The Company had an accumulated deficit of approximately $375.9 million as of December 31, 2022.

The Company has plans to obtain additional resources to fund its currently planned operations and expenditures for at least twelve months from the issuance of these consolidated financial statements through a combination of equity offerings, debt financings, collaborations, government contracts or other strategic transactions. The Company entered into a Standby Equity Purchase Agreement with YA II PN, Ltd. (“Yorkville”) on November 17, 2022 (as amended and restated on February 8, 2023), and a Standby Equity Purchase Agreement with B. Riley Principal Capital II, LLC (“B. Riley”) on January 8, 2023 whereby the Company has the right, but not the obligation, to sell to Yorkville and B. Riley up to $500.0 million each of shares of its Common Stock at its request any time during the 36 months following the date on which the registration statement related to each such purchase agreement has been declared effected by the SEC, subject to certain conditions (see Note 8 and Note 14). The Company’s plans are also dependent upon the success of future sales of ZTlido, which is still in the early stages of commercialization, and are dependent upon, among other things, the success of the Company’s marketing of ZTlido. Should the Company’s sales of ZTlido not materialize at the expected rate contemplated in the Company’s business plan, due to the COVID-19 pandemic or other factors, the Company believes that there are a number of ongoing and potential actions that would maintain its projected cash and projected financial position including but not limited to, additional reductions in general and administrative costs, sales and marketing costs, suspension or winding down of clinical development programs for SP-102, SP-103, and SP-104, and other discretionary costs. Although the Company believes such plans, if executed, should provide the Company with financing to meet its needs, successful completion of such plans is dependent on factors outside the Company’s control. As such, management cannot conclude that such plans will be effectively implemented within one year after the date that these consolidated financial statements are issued. As a result, management has concluded that the aforementioned conditions, among other things, raise substantial doubt about the Company’s ability to continue as a going concern for one year after the date the financial statements are issued.

As of December 31, 2020, approximately 14.7% of the outstanding capital stock of the Company was held by Itochu. On January 13, 2021, 34,889,868 shares of Legacy Scilex representing all outstanding capital stock of Legacy Scilex held by Itochu were acquired by non-related minority shareholders. Thus, Itochu is not a shareholder subsequent to January 13, 2021. During the years ended December 31, 2022, 2021, and 2020 the Company purchased approximately $6.7 million, $5.7 million, and $1.0 million respectively, of inventory from Itochu, a previous minority shareholder of the Company and a Developer in the aforementioned Product Development Agreement. These costs are recorded within cost of revenues and selling, general and administrative expenses in the Company’s statement of operations.

Semnur is party to an Assignment Agreement, dated August 6, 2013 (the “Assignment Agreement”), with Shah Investor LP (“Shah Investor”). Mahendra Shah, Ph.D., who has served on the Company’s board of directors since March 2019, is the managing partner of Shah Investor. Pursuant to the Assignment Agreement, Shah Investor assigned certain intellectual property to Semnur and Semnur agreed to pay Shah Investor a contingent quarterly royalty in the low-single digits based on quarterly net sales of any pharmaceutical formulations for local delivery of steroids by

injection developed using such intellectual property, which would include SP-102. Through December 31, 2022, the Company has made no royalty payments pursuant to the Assignment Agreement.

On January 1, 2017, a Transition Services Agreement (“TSA”) was executed between Scilex Pharma and Sorrento. Pursuant to the TSA, Sorrento agreed, at the Company’s request, to provide directly or indirectly certain administrative, financial, legal, tax, insurance, facility, information technology and other services. In addition to the services provided under the TSA, Sorrento retains insurance coverage on behalf of the Company. During the years ended December 31, 2022, 2021, and 2020 the total cost of services and insurance, including an agreed-upon markup, provided to the Company and recognized in general and administrative expenses was $3.8 million, $4.0 million, and $2.3 million, respectively.

On March 18, 2019, the Company entered into a note payable with Sorrento with an initial principal amount of $16.5 million for the acquisition of Semnur. The note is interest bearing at the lesser of (a) 10% simple interest per annum, and (b) the maximum interest rate permitted under law. Interest is due and payable annually. The note payable is payable upon demand and may be prepaid in whole or in part at any time without penalty or premium. During the years ended December 31, 2022, 2021, and 2020 Sorrento made advances to the Company in the amount of $27.5 million, $6.6 million, and $13.7 million respectively, under the note payable. All outstanding related party indebtedness immediately prior to the closing of the Business Combination was converted to equity pursuant to the Debt Exchange Agreement (defined below) and therefore the last day the debt outstanding was November 10, 2022 (see Note 12). The outstanding principal balance of the note on November 10, 2022 and December 31, 2021 was $47.1 million and $19.6 million, respectively, which was recorded under the current related party note payable in the Company’s consolidated balance sheets. As of November 10, 2022 and December 31, 2021, the Company had ending balances resulting from the accrued interest on the note payable of $7.2 million and $3.9 million, respectively, which was recorded under related party payable in the Company’s consolidated balance sheets. The proceeds from the note payable were used to finance the operations of the Company.

On October 5, 2018, Scilex Pharma issued to Sorrento a promissory note in the amount of approximately $21.7 million for certain amounts previously advanced to Scilex Pharma by Sorrento (the “Intercompany Note”). Scilex Pharma may borrow up to an aggregate of $25.0 million of principal amount under the note payable. The promissory note is interest bearing at the lesser of (a) 10% simple interest per annum, and (b) the maximum interest rate permitted under law. All outstanding principal amounts and accrued interest was due upon maturity on August 31, 2026. On October 22, 2018, Sorrento purchased from the Legacy Scilex 24,117,608 shares of the Legacy Scilex Common Stock in exchange for the repayment of $21.7 million of indebtedness under this promissory note. During the years ended December 31, 2022, 2021, and 2020, Sorrento made advances to Scilex Pharma in the amount of $0, $8.1 million, and $10.3 million respectively, under the promissory note. As of November 10, 2022 and December 31, 2021, the Company had ending balances resulting from the accrued interest on the note payable of $5.1 million and $3.1 million, respectively, which was recorded under related party payable in the Company’s consolidated balance sheets. As of November 10, 2022 and December 31, 2021, Scilex Pharma’s outstanding principal balance under the promissory note was $23.5 million, which was recorded under the non-current related party note payable in the Company’s consolidated balance sheets.

The Company received $35.0 million in February 2022 to fund the payment of Scilex Pharma Notes as described in Note 7. The $35.0 million received in February 2022 was due no earlier than February 2030 and was recorded under the non-current related party note payable in the Company’s consolidated balance sheets as of November 10, 2022.

Additional funding received from Sorrento was due on demand and recorded under the related party payable in the Company’s consolidated balance sheets. As of November 10, 2022, related party payables due to Sorrento included

$61.7 million to cover working capital requirements, $100.0 million for repurchases of Scilex Pharma Notes, and $18.2 million for litigation fees (see Note 7). As of December 31, 2021, related party payables due to Sorrento consisted of $35.7 million to cover working capital requirements, $51.0 million for repurchases of Scilex Pharma Notes, and $6.0 million to pay litigation fees. As of December 31, 2022, the Company had a $1.8 million related party receivable from Sorrento related to certain invoices paid on behalf of Sorrento, which was fully reserved (see Note 14).

On May 12, 2022, the Company entered into the Bill of Sale, with Sorrento (see Note 3). Pursuant to the Bill of Sale, the Company assumed all of Sorrento’s rights, liabilities and obligations under Aardvark Asset Purchase Agreement. The Company issued the 2022 Promissory Note to Sorrento as consideration transferred. The 2022 Promissory Note matures seven years from the date of issuance and bears interest at the rate equal to the lesser of (a) 2.66% simple interest per annum and (b) the maximum interest rate permitted under law. As of November 10, 2022, the outstanding balance, net of discount, under the 2022 Promissory Note was $4.2 million, which was recorded under the non-current related party note payable in the Company’s consolidated balance sheets.

Debt Exchange Agreement

On September 12, 2022, the Company and Scilex Pharma entered into a Contribution and Satisfaction of Indebtedness Agreement (the “Debt Exchange Agreement”) with Sorrento, pursuant to which (i) Sorrento shall contribute to the Company all amounts (including accrued interest thereon, if any) for certain loans and other amounts provided by Sorrento to the Company that remain outstanding as of immediately prior to the closing of the Business Combination (the “Aggregate Outstanding Amount” or “Outstanding Indebtedness”), including with respect to the Scilex Pharma Notes, an intercompany promissory note issued by Scilex Pharma to Sorrento in the amount of approximately $27.5 million for certain amounts previously advanced to Scilex Pharma by Sorrento, and the other notes payable to Sorrento described above (see Note 7), in exchange for the issuance by the Company to Sorrento of Preferred Stock of the Company, (ii) the Company shall contribute to Scilex Pharma the portion of such Outstanding Indebtedness that is owed by Scilex Pharma to Sorrento as a contribution of capital for no consideration, and (iii) upon the occurrence of the events described in clauses (i) and (ii), the Aggregate Outstanding Amount and the Outstanding Indebtedness shall be satisfied in full.

Pursuant to the terms of the Debt Exchange Agreement effective as of immediately prior to, and contingent upon, the closing of the Business Combination, Sorrento elected to contribute the Outstanding Indebtedness to the Company in exchange for the issuance by the Company to Sorrento of that number of shares of preferred stock, par value $0.0001 per share, of the Company (subject to adjustment for recapitalizations, stock splits, stock dividends and similar transactions) (the “Exchange Shares” and such transaction, the “Debt Contribution”) that is equal to (i) the Aggregate Outstanding Amount plus the amount equal to 10% of the Aggregate Outstanding Amount divided by (ii) $11.00 (rounded up to the nearest whole share); provided, that in no event would the Aggregate Outstanding Amount exceed $ 310,000,000.

On November 10, 2022, all existing related party indebtedness between Scilex, Scilex Pharma, and Sorrento totaling $290.6 million was converted into equity interests in the Company in connection with the consummation of the Business Combination and pursuant to the terms of the Debt Exchange Agreement. This amount was converted to 29,057,097 shares of Scilex Preferred Stock and 2,905,710 shares of the Company's Common Stock.

Commitments and Contingencies

10. Commitments and Contingencies

Product Development Agreement

In February 2013, Scilex Pharma became a party to a product development agreement (as amended, the “Product Development Agreement”) with two parties (the “Developers”), one of which is ITOCHU CHEMICAL FRONTIER Corporation (“Itochu”), pursuant to which the Developers will manufacture and supply lidocaine tape products, including ZTlido and SP-103 (the “Products”), for Scilex Pharma. The Developers initially developed, and have intellectual property rights relating to, the Products. Pursuant to the Product Development Agreement, Scilex Pharma acquired an exclusive right to develop and commercialize the Products worldwide except for Japan. The Developers are responsible for sourcing and supplying lidocaine for development and commercialization purposes.

Pursuant to the Product Development Agreement, Scilex Pharma is required to make aggregate royalty payments between 25% and 35% to the Developers based on net profits. During the year ended December 31, 2022, Scilex Pharma made royalty payments in the amount of $2.3 million. As of December 31, 2022, Scilex Pharma had ending balances of accrued royalty payables of $2.2 million. Net profits are defined as net sales, less cost of goods and marketing expenses. Net sales are defined as total gross sales of any Product, less all applicable deductions, to the extent accrued, paid or allowed in the ordinary course of business with respect to the sale of such Product, and to the extent that they are in accordance with U.S. GAAP. If Scilex Pharma were to sublicense the licensed technologies,

the Developers will receive the same proportion of any sublicensing fees received therefrom. The Product Development Agreement will continue in full force and effect until October 2, 2028, the date that is ten years from the date of the first commercial sale of ZTlido. The Product Development Agreement will renew automatically for subsequent successive one-year renewal periods unless Scilex Pharma or the Developers terminate it upon 6-month written notice.

On February 16, 2017, Scilex Pharma entered into a Commercial Supply Agreement (as amended, the “Supply Agreement”) with the two Developers to provide commercial supply of ZTlido and SP-103 to Scilex Pharma. The Supply Agreement contains standard terms regarding term, termination, payment, product quality and supply. In addition, the agreement provides additional terms regarding the calculation and amount of marketing expenses that may be deducted from net sales for purposes of determining the amount of net profit under the Product Development Agreement.

Exclusive Distribution Agreement

In August 2015, Scilex Pharma entered into an Exclusive Distribution Agreement (the “Distribution Agreement”) to appoint an exclusive third-party logistics distribution provider (the “Distributor”) and as an authorized distributor of record of ZTlido in the United States, its territories, possessions and commonwealths for an agreed schedule of fees, subject to a 3% annual adjustment. The Distribution Agreement has an initial term of three years following the first shipment of FDA-approved Product to a commercial customer and shall automatically renew for additional terms of one year each, unless written notice of termination is given by either party at least 30 days prior to the end of the initial term or any renewal term. In the event of Product recalls, Scilex Pharma is solely responsible for all Product recalls, except in the event where the recalls arise from the Distributor’s negligence or willful misconduct. Pursuant to the Distribution Agreement, Scilex Pharma will be responsible for delivery of Product to and from the Distributor’s facility, including all costs, expenses and risk of loss associated with such delivery. From late 2018 to early 2022, ZTlido was sold, and title was transferred, to the Distributor for distribution and sale to wholesalers for a fee of between 1% to 2% which was recorded as a gross-to-net sales adjustment. As the Company continues to expand the commercialization of ZTlido, it has expanded its direct distribution network to national and regional distributors and pharmacies since the beginning of April 2022. The Company currently holds all necessary wholesaler licenses and commenced selling directly to the main distributor customers as well as pharmacies in April 2022.

Sales Operations Services

In January 2016, Scilex Pharma entered into a project agreement with a vendor to provide sales operations services and detailing services, which was subsequently superseded by a new project agreement entered into in September 2018 (the “Project Agreement”). In connection with the detailing services, the Project Agreement provides that the vendor will provide Scilex Pharma with full-time sales representatives who shall detail the Product by making calls pursuant to a call plan on targets. These sales representatives are to be managed by field talent managers and a national project director, each of whom will also be provided by the vendor. In connection with the sales operation services, the vendor will provide certain services required for the initial implementation and ongoing operation of the sales force.

On July 1, 2020, Scilex Pharma and the vendor entered into a work order in which the parties agreed to convert substantially all of the sales representatives allocated under the Project Agreement to become employees of Scilex Pharma. The vendor continued to provide sales operations services, fleet management services and sample accountability services. The work order was in effect until June 30, 2022 and was extended for one year upon the mutual agreement of both parties. Either party may terminate the work order with 90 days’ notice. Scilex Pharma paid

an implementation fee of $59.0 thousand and will pay fixed monthly fees of $63.7 thousand to $65.8 thousand for ongoing services.

The Company recognized an expense of $0.9 million, $1.9 million, and $10.5 million within selling, general and administrative expenses for services performed for the years ended December 31, 2022, 2021, and 2020, respectively, including implementation fees, fixed monthly fees and pass-through costs.

Litigation

In the normal course of business, the Company may be named as a defendant in one or more lawsuits. Other than the following three lawsuits, the Company is not a party to any outstanding material litigation and management is not aware of any legal proceedings that, individually or in the aggregate, are deemed to be material to the Company’s financial condition or results of operations.

From time to time the Company may become involved in various legal proceedings, including those that may arise in the ordinary course of business.

Sanofi-Aventis U.S. LLC and Hisamitsu America, Inc. Litigation

On February 23, 2021, the Company filed an action in the U.S. District Court for the Northern District of California against Sanofi-Aventis U.S. LLC and Hisamitsu America, Inc., two manufacturers of OTC lidocaine patch products, alleging, among other things, false and deceptive advertising and unfair competition under the Lanham Act and California state laws by those companies regarding their respective OTC patch products (the “Sanofi-Aventis & Hisamitsu Litigation”). This lawsuit seeks, among other relief, damages and an injunction enjoining the defendants from continuing to make false or misleading statements of fact about their respective OTC lidocaine patch products. The defendants have filed motions to dismiss, which have narrowed slightly the Company's claims, but which motions the court has largely rejected. Discovery is proceeding. The case is currently scheduled for trial to begin on July 24, 2023. The Company cannot make any predictions about the outcome in this matter or the timing thereof.

Former Employee Litigation

On March 12, 2021, the Company filed an action in the Delaware Court of Chancery against Anthony Mack, former President of Scilex Pharma, and Virpax Pharmaceuticals, Inc. (“Virpax”), a company now headed by Mr. Mack, alleging, among other things, breach by Mr. Mack of his non-compete agreement with the Company, breach of fiduciary duty, and tortious interference by Virpax with that non-compete agreement (the “Former Employee Litigation”). This lawsuit seeks, among other relief, damages and an injunction enjoining Mr. Mack from further violating his non-compete agreement and enjoining Virpax from tortiously interfering with Mr. Mack’s non-compete agreement. The case was tried from September 12, 2022 to September 14, 2022. Post-trial briefing and closing arguments have been concluded and the case is under submission to the Court. The Company cannot make any predictions about the outcome in this matter or the timing thereof.

ZTlido Patent Litigation

On June 22, 2022, the Company filed a complaint against Aveva Drug Delivery Systems, Inc., Apotex Corp., and Apotex, Inc. (together, “Apotex”) in the U.S. District Court for the Southern District of Florida (the “ZTlido Patent Litigation”) alleging infringement of certain Orange Book listed patents covering ZTlido (the “ZTlido Patents”). The ZTlido Patent Litigation was initiated following the submission by Apotex, in accordance with the procedures set out

in the Hatch-Waxman Act, of an ANDA. Apotex’s ANDA seeks approval to market a generic version of ZTlido prior to the expiration of the ZTlido Patents and alleges that the ZTlido Patents are invalid, unenforceable, and/or not infringed. The Company is seeking, among other relief, an order that the effective date of any FDA approval of Apotex’s ANDA be no earlier than the expiration of the asserted patents listed in the Orange Book, the latest of which expires on May 10, 2031, and such further and other relief as the court may deem appropriate. Apotex is subject to a 30-month stay preventing it from selling a generic version of ZTlido during that time. The stay should expire no earlier than November 11, 2024. Trial in the ZTlido Patent Litigation has not yet been scheduled. The Company cannot make any predictions about the final outcome of this matter or the timing thereof.

Operating Leases

The Company leases administrative and research and development facilities under various non-cancelable lease agreements. Facility leases generally provide for periodic rent increases and may include options to extend. As of December 31, 2022, the Company’s leases have remaining lease terms of approximately 1.6 to 1.9 years. The term of the Company’s leases does not include extension options that were not reasonably certain to be exercised from its lease terms, ranging from 3 to 5 years. Many of the Company’s leases are subject to variable lease payments. Variable lease payments are recognized in the period in which the obligation for those payments are incurred, are not included in the measurement of the right-of-use assets or lease liabilities and are immaterial. Additionally, the Company subleases certain properties to third parties. Sublease income is recognized on a straight-line basis and is immaterial.

As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company calculates the associated lease liability and corresponding right-of-use asset upon lease commencement using a discount rate based on a credit-adjusted secured borrowing rate commensurate with the term of the lease. As of December 31, 2022, the Company has no finance leases.

The Company has evaluated the available evidence supporting the realization of its gross deferred tax assets, including the amount and timing of future taxable income, and has determined that it is more likely than not that the deferred tax assets will not be realized. Due to such uncertainties surrounding the realization of the deferred tax assets, the Company maintains a valuation allowance of $67.5 million against its deferred tax assets as of December 31, 2022. Realization of the deferred tax assets will be primarily dependent upon the Company's ability to generate sufficient taxable income prior to the expiration of its net operating losses.

As of December 31, 2022, the Company had $205.6 million and $106.9 million of federal and state net operating loss carryforwards, respectively. The net operating loss carryforwards begin to expire in 2035 and 2034 for federal and

state, respectively. The Company also had federal research and development income tax credits of $2.0 million which will begin to expire in 2035.

Internal Revenue Code Section 382 rules apply to limit a corporation's ability to utilize existing net operating loss and tax credit carryforwards once the corporation experiences an ownership change as defined in Section 382. For the years ended December 31, 2022 and 2021, there was no impact of such limitations on the Company’s income tax provision.

The Company is subject to taxation in U.S. federal and state tax jurisdictions. All of the Company’s tax years will remain open for three years for examination by the federal and state tax authorities from the date of utilizations of net operating loss. There are no active tax compliance audits as of December 31, 2022.

A reconciliation of the beginning and ending amount of unrecognized tax expense (benefits) is as follows for the years ended December 31, 2022, 2021, and 2020 (in thousands):


	2022		2021		2020
Beginning balance	$	408	$	406	$	385
Increase related to prior year tax positions		—		2		—
Decrease related to prior year tax positions		—		—		(4	)
Increase related to current year tax positions		—		—		25
Ending balance	$	408	$	408	$	406

At December 31, 2022, 2021, and 2020, $0.4 million, $0.4 million and $0.4 million, respectively, of the Company’s total unrecognized tax benefits, if recognized, would impact the effective tax rate, however given the full valuation allowance in the jurisdiction in which the unrecognized tax benefits relate to, the impact on the effective tax rate would be nil.

The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. No interest or penalties have been recognized as of and for the periods ended December 31, 2022, 2021, and 2020.

The Company believes that no material amount of the liabilities for uncertain tax positions are expected to reverse within 12 months of December 31, 2022.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Stockholders' Equity Note [Abstract]

SHAREHOLDERS’ EQUITY

8. Stockholders’ Equity

The consolidated statement of stockholders’ equity has been retroactively adjusted for all periods to reflect the Business Combination and reverse recapitalization described in Note 1. The balances as of December 31, 2022 and 2021 from the consolidated financial statements of the Company as of that date, share activity (Preferred Stock, Common Stock, and additional paid-in-capital) and per share amounts were retroactively adjusted, where applicable, using the Common Stock Exchange Ratio.

Common Stock

Upon the closing of the Business Combination, pursuant to the terms of the Amended and Restated Certificate of Incorporation, the Company authorized 740,000,000 shares of Common Stock with a par value of $0.0001. As of December 31, 2022 and December 31, 2021, there were 141,348,856 shares issued and 132,858,484 of Common Stock outstanding, respectively.

In connection with the closing of the Business Combination, all previously issued and outstanding shares of Legacy Scilex Common Stock and Legacy Scilex stock options were converted into shares of Common Stock pursuant to the Common Stock Exchange Ratio. The Company has retroactively adjusted shares issued and outstanding prior to November 10, 2022 to give effect to the Common Stock Exchange Ratio to determine the number of shares of Common Stock into which they were converted.

Voting

The holders of the Common Stock are entitled to one vote for each share of the Common Stock held at all meetings of stockholders.

Dividends

Common stockholders are entitled to receive dividends whenever funds are legally available and when declared by the Company's board of directors. No dividends have been declared as of December 31, 2022.The Stockholder Agreement, dated as of September 12, 2022, between Vickers and Sorrento (the “Stockholder Agreement”), provides that the Company will be prohibited from taking certain actions without the consent of Sorrento. Such actions include, among other things, the payment of dividends on shares of the Common Stock.

Liquidation Rights

Subject to the rights of the holders of Preferred Stock, in the event of our liquidation, dissolution or winding-up, holders of Common Stock are entitled to share equally in the assets available for distribution after payment of all creditors.

Preferred Stock

Upon the closing of the Business Combination, $290.6 million of all existing related party indebtedness between Scilex, Scilex Pharma, and Sorrento were cancelled in exchange for the issuance of preferred shares of Scilex (“Series A Preferred Shares” or “Series A Preferred Stock”). In connection with the closing of the Business Combination, all issued Scilex Series A Preferred Shares were cancelled and converted into the right to receive 1) one share of

domesticated parent preferred shares (“New Scilex Preferred Stock” or “Preferred Stock”) par value of $0.0001 per share, and 2) one-tenth of one domesticated parent common stock (“New Scilex Common Stock” or “Common Stock” and such transaction including cancellation of all the existing related party indebtedness in exchange for Preferred Stock and Common Stock, the “Conversion” or “Contribution”).

Prior to the Conversion, Legacy Scilex filed a Second Amended Certificate of Incorporation (defined below) to increase the authorized number of shares to 45,000,000 shares and a Certificate of Designation (“Certificate of Designation”) to designate the rights, preferences, and privileges of Scilex Series A Preferred Shares. In connection with the closing of the Business Combination, the Company filed the Certificate of Designation and issued 29,057,097 shares of the Series A Preferred Stock to Sorrento. As of December 31, 2022, there were 29,057,097 shares of Preferred Stock outstanding. There were no Preferred Stock outstanding at December 31, 2021.

The Company’s Board of Directors have authority to issue such shares of Preferred Stock in one or more series, to establish, from time to time the number of shares to be included in each such series, and to fix the dividend, voting, and other rights, preferences, and privileges of the shares. Other than the Series A Preferred Stock issued to Sorrento in connection with the closing of the Business Combination, there are no other Preferred Stock outstanding and the Company has no current plans to issue any other shares of preferred stock.

Voting

The holders of shares of Preferred Stock will be entitled to vote, together with the holders of shares of Common Stock and not separately as a class, on all matters upon which holders of shares of Common Stock have the right to vote. The holders of shares of Preferred Stock will be entitled to one vote for each share of Common Stock that such share of Preferred Stock would otherwise be convertible into pursuant to a deemed conversion on the record date for the determination of the stockholders entitled to vote.

Pursuant to the Stockholder Agreement, holders of Series A Preferred Stock have the right to designate each director to be nominated, elected or appointed to the Board of Directors of the Company. The Series A Preferred Stock also has certain protective provisions, such as requiring a written consent of the holders of Series A Preferred Stock to change or amend their rights, powers, privileges, limitations and restrictions.

Dividends

Holders of the Preferred Stock are not entitled to dividends unless the Company pays dividends to holders of the Common Stock and shall be entitled to receive, when, as and if declared by our Board, such dividends (whether in cash or other property) as are paid to holders of the Common Stock to the same extent as if such holders of Series A Preferred Stock had been deemed to convert their shares of Preferred Stock into Common Stock and had held such shares of Common Stock on the record date for such dividends and distributions. Such payments will be made concurrently with the dividend or distribution to the holders of the Common Stock.

Liquidation Rights

Subject to the rights of the holders of parity shares (if any), in the event of our liquidation, dissolution or winding-up, holders of Preferred Stock rank senior to the Common Stock and are entitled to share equally in the assets available for distribution after payment of all creditors.

Assumed Public Warrants and Private Warrants

The warrants will expire five years after the completion of the Business Combination or earlier upon redemption or liquidation.

Each warrant entitles the holder to purchase one share of Common Stock for $11.50 per share.

If the reported last sale price of the Common Stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to the warrant holders, the Company may redeem all the Public Warrants at a price of $0.01 per warrant upon not less than 30 days’ prior written notice.

The Company will not be required to net cash settle the warrants. As of December 31, 2022, there are 6,899,988 Public Warrants outstanding.

average price of the Common Stock for any trading day (“VWAP”) during the two consecutive trading days commencing on the date of delivery of a written purchase notice to Yorkville (each, a “Yorkville Advance Notice”).

As consideration for Yorkville's commitment to purchase shares of Common Stock at the Company’s direction upon the terms and subject to the conditions set forth in the Yorkville Purchase Agreement, upon execution of the Yorkville Purchase Agreement, the Company issued 250,000 shares of Common Stock to Yorkville and paid $10.0 thousand in structuring fees.

Acquisitions

3. Acquisitions

SP-104 Acquisition

On May 12, 2022, the Company entered into a bill of sale and assignment and assumption agreement (the “Bill of Sale”), with Sorrento. Pursuant to the Bill of Sale, Sorrento sold, conveyed, assigned and transferred to the Company all of its rights, title and interest in and to Sorrento’s Delayed Burst Release Low Dose Naltrexone (“DBR-LDN”) asset and intellectual property rights, for the treatment of chronic pain, fibromyalgia and chronic post-COVID syndrome (collectively, the “SP-104 Assets”). These assets had previously been acquired by Sorrento from Aardvark

Therapeutics, Inc. (“Aardvark”) in April 2021 pursuant to an asset purchase agreement (the “Aardvark Asset Purchase Agreement”). Pursuant to the Bill of Sale, the Company assumed all of Sorrento’s rights, liabilities and obligations under the Aardvark Asset Purchase Agreement (the “SP-104 Acquisition”).

As consideration for the SP-104 Acquisition, the Company issued a promissory note in the aggregate principal amount of $5.0 million to Sorrento (the “2022 Promissory Note”). Upon issuance of the note, the Company recorded a related party note payable of $4.1 million, net of discount, with an offset to additional paid in capital, given the common control relationship between Sorrento and the Company. The 2022 Promissory Note matures seven years from the date of issuance and bears interest at the rate equal to the lesser of (a) 2.66% simple interest per annum and (b) the maximum interest rate permitted under law. The 2022 Promissory Note is payable in cash, shares of the Company’s common stock or any combination thereof, at the Company’s sole discretion, and may be prepaid in whole or in part at any time without penalty. On November 10, 2022, the 2022 Promissory Note was converted to equity, pursuant to the terms of the Debt Exchange Agreement (See Note 12).

As the successor to the Aardvark Asset Purchase Agreement, the Company is obligated to pay Aardvark (i) $3,000,000, upon initial approval by the FDA of a new drug application for the SP-104 Assets (which amount may be paid in shares of the Company’s common stock or cash, in the Company’s sole discretion) (the “Development Milestone Payment”) and (ii) $20,000,000, in cash, upon achievement of certain net sales by the Company of a commercial product that uses the SP-104 Assets (the “Sales Milestone Payment”). The Company will also pay Aardvark certain royalties in the single digits based on percentages of annual net sales by the Company of a commercial product that uses the SP-104 Assets.

The transaction was accounted for as an asset acquisition as substantially all the value of the gross assets was concentrated in a single asset, SP-104 Assets. The Sales Milestone Payment and sale volume-based future royalties were determined to meet a scope exception for derivative under ASC Topic 815, Derivatives and Hedging, and will not be recognized until the contingencies are realized in accordance with the Company’s accounting policy for contingent consideration in an asset acquisition. The Development Milestone Payment represents a liability within the scope of ASC Topic 480, Distinguishing Liabilities from Equity, which will be measured at fair value each reporting period. As of December 31, 2022, the contingent consideration of $0.2 million associated with Development Milestones Payment was recognized under other long-term liabilities.

GLOPERBA License Agreement

On June 14, 2022, the Company entered into a license agreement (the “Romeg License Agreement”) with RxOmeg Therapeutics, LLC (a/k/a Romeg Therapeutics, Inc.) (“Romeg”). Pursuant to the Romeg License Agreement, among other things, Romeg granted the Company (1) a transferable license, with the right to sublicense, under the patents and know-how specified therein (with such license to know-how being exclusive for the limited purposes specified therein) to (i) commercialize the pharmaceutical product comprising liquid formulations of colchicine for the prophylactic treatment of gout in adult humans (the “Initial Licensed Product” or “GLOPERBA”) in the United States of America (including its territories) (the “Territory”), (ii) develop other products comprising the Initial Licensed Product as an active pharmaceutical ingredient (the “Licensed Products”) and commercialize any such products and (iii) manufacture Licensed Products anywhere in the world, solely for commercialization in the Territory; and (2) an exclusive, transferable license, with right to sublicense, to use the trademark GLOPERBA and logos, designs, translations, and modifications thereof in connection with the commercialization of the Initial Licensed Product solely in the Territory. The Initial Licensed Product, GLOPERBA, was approved and made available in the United States in 2020.

As consideration for the license under the Romeg License Agreement, the Company paid Romeg an up-front license fee of $2.0 million, and has agreed to pay Romeg (a) upon the Company’s achievement of certain net sales milestones, certain milestone payments in the aggregate amount of up to $13.0 million, (b) certain royalties in the mid-single digit to low-double digit percentages based on annual net sales of the Licensed Product by the Company during the applicable royalty term under the Romeg License Agreement, and (c) minimum quarterly royalty payments totaling $7.1 million commencing on the first year anniversary of the effective date of the Romeg License Agreement and ending on the later of (i) expiration of the last to expire of the licensed patents covering the Licensed Products in the Territory or (ii) the tenth anniversary of the effective date of the Romeg License Agreement.

The transaction was accounted for as an asset acquisition since substantially all the value of the gross assets was concentrated in a single asset, which is the Initial Licensed Product. In connection with the Romeg License Agreement, the Company recorded an intangible asset for acquired licenses of $5.7 million, which is comprised of the upfront license fee of $2.0 million and a deferred consideration of $3.7 million that is the present value of the future minimum royalty payments and immaterial transaction costs. The contingent sales milestones and sale volume-based future royalties were determined to meet a scope exception for derivative under ASC Topic 815, and will not be recognized until the contingencies are realized. No contingent consideration was recognized as a liability or included in the fair value of the assets as of December 31, 2022. The Company determined the useful life of the intangible asset to be 15 years, which approximates the life of the licensed patents covering the Initial Licensed Product.

Total liabilities measured at fair value	$	35,700	$	—	$	—	$	35,700

Cash and cash equivalents

The Company’s financial assets carried at fair value are comprised of cash and cash equivalents. Cash and cash equivalents consist of money market accounts and bank deposits which are highly liquid and readily tradable. These assets are valued using inputs observable in active markets for identical securities.

Derivative liabilities

The Company recorded a gain of $8.3 million, loss of $0.3 million, and gain of $0.8 million on derivative liabilities for the years ended December 31, 2022, 2021, and 2020, respectively, which was attributed to compound derivative liabilities associated with the Scilex Pharma Notes (see Note 7) and Private Warrants. The fair value of the derivative liability associated with the Scilex Pharma Notes decreased by $30.4 million immediately after entry into Amendment No. 4 (see Note 7) associated with the Scilex Pharma Notes on June 2, 2022. The fair value of the derivative liability associated with the Scilex Pharma Notes was estimated using the discounted cash flow method combined with a Monte Carlo simulation model including consideration of the terms of Amendment No. 4. Significant Level 3 assumptions used in the measurement included a 6.1% risk adjusted net sales forecast and an effective debt yield of 21.5%. The Scilex Pharma Notes were fully extinguished in September 2022 (see Note 7) and, as such, there were no remaining loan derivative liabilities associated with the Scilex Pharma Notes as of December 31, 2022. At the closing of the Business Combination, the Company assumed a derivative warrant liability of $2.5 million related to Private Warrants (See Note 8). The fair value of derivative warrant liability related to Private Warrants was $1.2 million as of December 31, 2022.

The following table includes a summary of the derivative liabilities measured at fair value using significant unobservable inputs (Level 3) during the year ended December 31, 2022:


	Fair value
Ending Balance at December 31, 2019	$	33,400
Loan derivative liability		2,800
Re-measurement of fair value		(800	)
Ending Balance at December 31, 2020	$	35,400
Re-measurement of fair value		300
Balance at December 31, 2021	$	35,700
Private Warrant liability acquired as part of the Business Combination		2,545
Forfeiture of Private Warrants		1,696
Change in fair value measurement		(38,710	)
Balance at December 31, 2022	$	1,231

Warrant Liability Measurement

The derivative warrant liability was valued using the Black-Scholes option pricing model, which is considered to be Level 3 fair value measurement. The primary unobservable input utilized in determining the fair value of the warrant is the expected volatility of the Common Stock. The expected volatility assumption is based on historical volatilities of comparable companies whose share prices are publicly available as well as the implied volatility of the Public Warrants. A summary of the inputs used in valuing the derivative warrant liabilities is as follows:


	December 31, 2022			November 10, 2022
	Fair value			Fair Value
Equity Value	$	3.99		$	9.01
Exercise Price	$	11.50		$	11.50
Term (in years)		4.86			5.00
Volatility		35.0	%		10.0	%
Risk-free rate		3.94	%		3.91	%
Dividend yield		0.00	%		0.00	%
Call option value	$	0.30		$	0.62

Contingent Consideration

The Development Milestone Payment represents a liability under the scope of ASC Topic 480, Distinguishing Liabilities from Equity, as it pertains to a potential contractual obligation to settle a fixed value in a variable number of shares of Common Stock. Upon the achievement of FDA approval for a new drug application for SP-104, the Company will transfer $3.0 million in cash or shares of Common Stock, at the discretion of the Company. The fair value of the contingent consideration liability associated with Development Milestone Payment was estimated using a probability-weighted discounted cash flow method. Significant Level 3 assumptions included the likelihood of receiving FDA approval for SP-104, expected timing for receipt of FDA approval for SP-104, and a discount rate of 10.0%. As of December 31, 2022, the fair value of contingent consideration related to the Development Milestone Payment was $0.2 million.

There were no transfers between fair value measurement levels during the years ended December 31, 2022, 2021, and 2020.

Goodwill and Intangible Assets

6. Goodwill and Intangible Assets

As of December 31, 2022 and December 31, 2021, the Company had recorded goodwill of $13.5 million. The Company performed a qualitative test for goodwill impairment during the fourth quarter of 2022. Based upon the results of the qualitative testing, the Company concluded that it is more-likely-than-not that the fair value of the Company’s goodwill was in excess of the carrying value and therefore performing the first step of the two-step

impairment test was unnecessary. The conclusion has not changed as of December 31, 2022 and no goodwill impairment was recognized for the years ended December 31, 2022 and 2021.

The Company’s intangible assets, excluding goodwill, are composed of patent rights, acquired technology, acquired licenses, and assembled workforce. Amortization of the intangible assets that have finite useful lives is generally recorded on a straight-line basis over their useful lives. A summary of the Company’s identifiable intangible assets as of December 31, 2022 and December 31, 2021 is as follows (in thousands):


	December 31, 2022

Assembled workforce		500		275		225
Total intangible assets	$	55,070	$	16,268	$	38,802

On June 14, 2022, the Company entered into Romeg License Agreement to acquire an exclusive license to use GLOPERBA from Romeg (see Note 3). The Company determined the acquisition of licenses to be an asset acquisition. The fair value of consideration transferred of $5.7 million was assigned to acquired licenses with an amortization period of approximately 15 years.

As of December 31, 2022, the weighted average remaining life for identifiable intangible assets was 10.4 years. Aggregate amortization expense was $3.9 million, $3.7 million, and $3.7 million for the years ended December 31, 2022, 2021, and 2020, respectively. Patent rights and acquired technology are amortized over a 15-year period. Assembled workforce is amortized over a 5-year period.

2018 Purchase Agreements and Indenture

On September 7, 2018, Scilex Pharma and Sorrento entered into Purchase Agreements (the “2018 Purchase Agreements”) with certain investors (collectively, the “Scilex Pharma Note Purchasers”). Pursuant to the 2018 Purchase Agreements, on September 7, 2018, Scilex Pharma, among other things, issued and sold to the Scilex Pharma Note Purchasers senior secured notes due 2026 in an aggregate principal amount of $224.0 million (the “Scilex Pharma Notes”) for an aggregate purchase price of $140.0 million (the “Offering”). The Scilex Pharma Notes were governed by an indenture (as amended, the “Indenture”) with Scilex Pharma, as issuer, U.S. Bank National Association, a national banking association, as trustee (the “Trustee”) and collateral agent (the “Collateral Agent”), and Sorrento, as guarantor. Pursuant to the Indenture, Sorrento agreed to irrevocably and unconditionally guarantee, on a senior unsecured basis, the punctual performance and payment when due of all obligations of Scilex Pharma under the Indenture (the “Guarantee”).

The principal amount of the Scilex Pharma Notes increased by $28.0 million on February 15, 2022 as a result of actual cumulative net sales of ZTlido from the issue date of the Scilex Pharma Notes through December 31, 2021 not equal or exceeding $481.0 million. As a result, the Company recorded the increase of $28.0 million in principal and non-operating expense at December 31, 2021.

Effective February 14, 2022, Scilex Pharma issued to Sorrento a draw notice under the Letter of Credit as required under the terms of the Indenture because actual cumulative net sales of ZTlido from the issue date of the Scilex Pharma Notes through December 31, 2021 were less than a specified sales threshold for such period. As a result of the draw notice being issued, Sorrento paid to Scilex Pharma $35.0 million in a single lump-sum amount as a subordinated loan and Scilex Pharma became subject to a minimum cash requirement of $10.0 million. In February 2022, Scilex Pharma repurchased Scilex Pharma Notes from the holders thereof on a pro rata basis in an aggregate amount equal to $20.0 million.

On June 2, 2022, Sorrento and Scilex Pharma entered into a Consent Under and Amendment No. 4 to Indenture (the “Amendment No. 4”) with U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association) and the Scilex Note Purchasers. Pursuant to Amendment No. 4, (1) on June 3, 2022, Scilex Pharma repurchased approximately $41.4 million of the aggregate principal amount of the outstanding Scilex Pharma Notes at 100% of the principal amount thereof, (2) the Scilex Note Purchasers agreed that Scilex Pharma can repurchase the remaining principal amount of the Scilex Pharma Notes at any time on or before September 30, 2022 for $41.4 million (subject to reduction for any quarterly royalty payments) and upon such repurchase the Scilex Note Purchasers will forgive and discharge $28.0 million of the aggregate principal amount of the Scilex Pharma Notes (the “Early Paydown Provision”), (3) the minimum cash requirement under the Indenture was reduced to $5.0 million in aggregate unrestricted cash equivalents at the end of each calendar month, and (4) the maximum aggregate principal amount on the promissory note issued by Scilex Pharma to Sorrento on October 5, 2018 was increased from up to $25.0 million to up to $50.0 million. The Company funded the repurchase with cash-on-hand and $15.0 million received from Sorrento on June 2, 2022. The Company concluded that the Amendment No. 4 was a troubled debt restructuring for accounting purposes. The future undiscounted cash flows of the Scilex Pharma Notes were higher than the carrying value of the Scilex Pharma Notes at the time of the entry into the Amendment No. 4, and accordingly, no gain was recognized in the quarter ended June 30, 2022. Due to a decrease of $30.4 million in the fair value of the Scilex Notes Derivative caused by the Amendment No. 4, the carrying value of the Scilex Notes was increased by $30.4 million.

In September 2022, the Company exercised the Early Paydown Provision to fully extinguish the Scilex Pharma Notes. In August and September 2022, the Company made principal payments towards the outstanding Scilex Pharma Notes totaling $1.7 million and $39.7 million, respectively. Pursuant to Amendment No. 4, $28.0 million of principal amount on the Scilex Pharma Notes was forgiven by the Scilex Pharma Note Purchasers and the Scilex Pharma Notes were fully extinguished in September 2022. The Company funded the repurchase with cash-on-hand and $34.0 million received from Sorrento on September 28, 2022. The Company recorded a gain on debt extinguishment of $28.6 million as a result of the extinguishment.

Borrowings of the Scilex Notes consisted of the following (in thousands):


	December 31, 2021
Principal	$	133,997
Unamortized debt discount		(30,597	)
Unamortized debt issuance costs		(2,228	)
Carrying value		101,172
Current portion		(29,135	)
Long term portion		72,037
Estimated fair value	$	115,400

The Company made principal payments of $106.0 million, $45.9 million, and $69.8 million during the years ended December 31, 2022, 2021, and 2020, respectively. The amount of debt discount and debt issuance costs included in interest expense for the years ended December 31, 2022, 2021, and 2020 was approximately $3.1 million, $7.9 million and $10.7 million, respectively. The Company recorded a gain on debt extinguishment of $28.6 million, a loss on debt extinguishment of $12.5 million, and no gain/loss on debt extinguishment in connection with its repayments of principal made during the years ended December 31, 2022, 2021, and 2020, respectively.

Related Party Notes Payable

On October 5, 2018, Scilex Pharma issued to Sorrento a promissory note (see Note 12). On March 18, 2019, the Company entered into a note payable with Sorrento (see Note 12). On February 14, 2022, Sorrento paid to Scilex Pharma $35.0 million in a single lump-sum amount as a subordinated loan (see Note 12). On May 12, 2022, the Company issued Sorrento a promissory note of $5.0 million in exchange for the SP-104 Assets (see Note 3). On November 10, 2022, all existing related party indebtedness between Scilex, Scilex Pharma, and Sorrento was converted into equity interests in the Company in connection with the consummation of the Business Combination and pursuant to the terms of the Debt Exchange Agreement (see Note 12).

2020 Revolving Credit Facility

On December 14, 2020, Scilex Pharma entered into the Credit and Security Agreement (the “Credit Agreement”) with CNH Finance Fund I, L.P. (“CNH”) which provides Scilex Pharma with the ability to incur indebtedness under an accounts receivable revolving loan facility in an aggregate amount of $10.0 million and the incurrence of liens and the pledge of collateral to CNH in connection with the revolving loan facility. Under the terms of the Credit Agreement, interest will accrue daily on the principal amount outstanding at a rate per annum equal to the Wall Street Journal Prime Rate plus 1.75%. All indebtedness incurred and outstanding will be due and payable in full on January 1, 2024; unless the Credit Agreement is earlier terminated. As of December 31, 2021, the outstanding balance was $8.8 million. On February 16, 2022, the Company notified CNH that it was terminating the Credit Agreement, effective March 18, 2022. Upon termination, all principal balances and interest accrued were settled.

Stock Incentive and Employee Benefit Plans

12 Months Ended

Dec. 31, 2022

Share-Based Payment Arrangement [Abstract]

Stock Incentive and Employee Benefit Plans

9. Stock Incentive and Employee Benefit Plans

The consolidated statements of stockholders’ equity / (deficit) have been retroactively adjusted for all periods to reflect the Business Combination and reverse recapitalization described in Note 1. The balances as of December 31, 2022, 2021, 2020 from the consolidated financial statements of the Company as of that date, share activity (stock options) and per share amounts were retroactively adjusted, where applicable, using the Common Stock Exchange Ratio.

2017 Equity Incentive Plan

In June 2017, Scilex Pharma adopted the Scilex Pharmaceuticals Inc. 2017 Equity Incentive Plan (the “Scilex Pharma 2017 Plan”). The Scilex Pharma 2017 Plan reserved 24.0 million shares of Scilex Pharma common stock. Stock options granted under the Scilex Pharma 2017 Plan typically vest 1/4th of the shares on the first anniversary of the vesting commencement date and 1/48th of the remaining options vest each month thereafter. The Scilex Pharma 2017 Plan was amended and restated on July 5, 2018.

In connection with the corporate reorganization in March 2019, the Scilex Pharma 2017 Plan was terminated, and each option to purchase Scilex Pharma’s common stock outstanding and unexercised immediately prior to reorganization was cancelled and substituted for that number of options to acquire Legacy Scilex Common Stock.

Scilex Holding Company 2019 Stock Option Plan

The Board of Directors of the Company adopted the Scilex Holding Company 2019 Stock Option Plan (the “2019 Stock Option Plan” or “Prior Plan”) on May 28, 2019. The 2019 Stock Option Plan was approved by the Company’s stockholders on June 7, 2019. As of December 31, 2019, 30.0 million shares of Scilex Common Stock of the Company were reserved for issuance pursuant to the 2019 Stock Option Plan. Stock options granted under the 2019 Stock Option Plan typically vest with respect to 1/4th of the shares on the first anniversary of the vesting commencement date and 1/48th of the remaining shares on each monthly anniversary thereafter.

Upon the consummation of the Business Combination, the 2019 Stock Option Plan was terminated and no further awards were granted under the 2019 Stock Option Plan thereafter. However, the 2019 Stock Option Plan will continue to govern outstanding awards granted under the terms of the Equity Incentive Plan (defined below).

Scilex Holding Company 2022 Equity Incentive Plan

The Board of Directors of the Company adopted the Scilex Holding Company 2022 Equity Incentive Plan (the “Equity Incentive Plan”) on October 17, 2022. The 2022 Equity Incentive Plan was approved by the stockholders and became effective on November 9, 2022.

The total number of common shares for which incentive stock options (“ISOs”) may be granted under the Equity Incentive Plan is not to exceed 14,622,712 shares plus a number of shares of Common Stock equal to the number of shares subject to outstanding stock awards granted under the Prior Plan (“Returning Shares”), if any, as such shares become available from time to time, which the amount will be increased commencing on January 1, 2023 and ending on (and including) January 1, 2032, in an amount equal to the lesser of (i) 4% of the total number of shares of Common Stock outstanding on December 31 of the preceding year, (ii) 7,311,356 shares of Common Stock, and (iii) such number of shares of the Common Stock determined by the Board or the compensation committee of the Board prior to January 1 of a given year.

As of December 31, 2022, there were no options to purchase shares of Common Stock outstanding under the Equity Incentive Plan and options to purchase 16,939,436 shares of the Common Stock were outstanding under previous plans.

Total stock-based compensation recorded within operating expenses was $5.3 million, $5.8 million, and $5.4 million for the years ended December 31, 2022, 2021, and 2020, respectively.

The total unrecognized compensation costs related to unvested employee and non-employee stock option grants as of December 31, 2022 was $2.7 million and the weighted average period over which these grants are expected to vest is 1.4 years.

Scilex Holding Company 2022 Employee Stock Purchase Plan

On October 17, 2022, the Board adopted the Scilex Holding Company 2022 Employee Stock Purchase Plan (the “ESPP”). The ESPP was approved by the stockholders and became effective on November 9, 2022. The purpose of the ESPP is to secure and retain the services of new employees, to retain the services of existing employees, and to provide incentives for such individuals to exert maximum efforts toward the success of the Company.

The ESPP includes two components. One component is designed to allow eligible U.S. employees to purchase the Common Stock in a manner that may qualify for favorable tax treatment under Section 423 of the Internal Revenue Code of 1986 (“Code”) (the “423 Component”) and accordingly, it will be construed in a manner that is consistent with the requirements of Section 423 of the Code. The other component will permit the grant of purchase rights that do not qualify for such favorable tax treatment (the “Non-423 Component”) in order to allow deviations necessary to permit participation by eligible employees who are foreign nationals or employed outside of the U.S. while complying with applicable foreign laws, and except as otherwise provided in the ESPP or determined by the Board, it will operate and be administered in the same manner as the 423 Component.

The Board administers the ESPP and will have the authority to determine how and when purchase rights are granted and the provisions of each offering. Initially, the total number of shares of the Common Stock that may be issued under the ESPP will not exceed 1,462,271 shares of the Common Stock. The number of shares of the Common Stock that will be reserved for issuance will automatically increase on January 1 of each year for a period of up to ten years, commencing on January 1, 2023 and ending on (and including) January 1, 2032, in an amount equal to the lesser of

(i) 1% of the total number of shares of the Common Stock outstanding on December 31 of the immediately preceding calendar year; (ii) 1,827,839 shares of the Common Stock; and (iii) such number of shares of the Common Stock determined by the Board or the compensation committee of the Board prior to January 1 of a given year, provided however, that the Board may act prior to January 1 of a given calendar year to provide that there will be no increase for such calendar year or the increase for such year will be a lesser number of shares than the amount set forth in clauses (i) to (iii) above. As of December 31, 2022, there were no shares outstanding under the ESPP.

Option Valuation

The Company calculates the fair value of stock-based compensation awards granted to employees and nonemployees using the Black-Scholes option-pricing method. The Black-Scholes option-pricing method requires the use of subjective assumptions, including stock price volatility, the expected life of stock options, risk free interest rate and the fair value per share of the underlying common stock on the date of grant. The assumptions used in the Black-Scholes option-pricing method related to options issued to employees and nonemployees for the year ended 2020 is set forth below:


	Year Ended December 31,
	2020
Weighted –average grant date fair value	$	1.23
Expected dividend yield	0.00		%
Expected stock-price volatility	90.00		%
Risk-free interest rate	0.53		%
Term of options		5.6
Fair value per share of common stock on date of grant	$	1.72
Exercise price	$	1.72

Expected dividend yield. The Company bases the expected dividend yield assumption on the fact that the Company has never paid cash dividends and has no present intention to pay cash dividends on the Company’s common stock.

Expected stock-price volatility. The expected stock-price volatility assumption is based on volatilities of a peer group of similar companies whose share prices are publicly available. The peer group was developed based on companies in the transdermal patch industry. In selecting the peer group, management considered publicly-traded transdermal patch companies with existing clinical stage branded and generic transdermal patches. Management further considered the development stage of the peer group companies.

Risk-free interest rate. The Company bases the risk-free interest rate assumption on the U.S. Treasury’s rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued.

Expected term of options. The expected term of options represents the period of time when options are expected to be outstanding. Because the Company does not have historic exercise behavior, the Company determines the expected term assumption for options issued to directors and employees using the simplified method, which is an average of the contractual term of the option and its ordinary vesting period.

The following represents a summary of the options outstanding at December 31, 2022, 2021, and 2020 and changes during the years then ended (in thousands, other than weighted-average exercise price):


	Options			Weighted average exercise price		Aggregate Intrinsic Value

Employee Benefit Plan

The Company maintains a defined contribution 401(k) plan available to eligible employees, which is administered by Sorrento. Employee contributions are voluntary and are determined on an individual basis, limited to the maximum amount allowable under federal tax regulations. The Company made matching contributions to the 401(k) plan totaling $0.3 million for each of the years ended December 31, 2022, 2021, and 2020, respectively.

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

13. Loss Per Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, Earnings Per Share. The Company has two classes of shares, which are referred to as Common Stock and Preferred Stock.

Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. Net loss per share has been retrospectively adjusted for all periods presented prior to the Business Combination. The retroactive adjustment is based on the same number of weighted average shares outstanding in each historical period.

For the years ended December 31, 2022, 2021, and 2020, basic loss per share is computed using the two-class method. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating securities according to dividends or dividend equivalents and participation rights in undistributed earnings. Preferred Stock is not contractually required to share in net losses of the Company.

The following table sets forth the reconciliation of basic and diluted loss per share for the years ended December 31, 2022, 2021, and 2020 (in thousands except per share data):


	Year Ended December 31,
	2022			2021			2020
Net loss attributable to Scilex	$	(23,364	)	$	(88,424	)	$	(47,519	)
Net loss attributable to participating securities	$	—		$	—		$	—
Net loss attributable to common stockholders	$	(23,364	)	$	(88,424	)	$	(47,519	)
Weighted average common shares outstanding		134,226			132,858			132,891
Effect of Dilutive Securities		—			—			—
Denominator for Diluted Loss per Share - Adjusted for Dilutive Securities		134,226			132,858			132,891
Basic and Diluted Loss Per Share	$	(0.17	)	$	(0.67	)	$	(0.36	)

The following potentially dilutive outstanding securities were excluded from the computation of diluted net loss per share because their effect would have been anti-dilutive for the periods presented:


	Year Ended December 31,
	2022		2021		2020
Stock options		16,939,093		18,967,724		20,746,432

Subsequent Events [Abstract]

SUBSEQUENT EVENTS

14. Subsequent Events

The Company has evaluated subsequent events for recognition and disclosure purposes in the audited consolidated financial statements as of December 31, 2022. Except as described below, or as otherwise indicated in the footnotes, the Company has concluded that no events or transactions have occurred that require disclosure.

B. Riley Standby Equity Purchase Agreement

On January 8, 2023, the Company entered into a Standby Equity Purchase Agreement (the "B. Riley Purchase Agreement") with B. Riley, whereby the Company shall have the right, but not the obligation, to sell to B. Riley up to $500.0 million of its shares of the Company’s Common Stock at the Company's request any time during the 36 months following the execution of the B. Riley Purchase Agreement, subject to certain conditions. The Company expects to use the net proceeds received from this for working capital and general corporate purposes.

As consideration for B. Riley’s commitment to purchase shares of Common Stock at the Company’s direction upon the terms and subject to the conditions set forth in the B. Riley Purchase Agreement, the Company issued 250,000 shares of Common Stock to B. Riley in connection with the execution of the B. Riley Purchase Agreement on January 12, 2023.

Scilex Holding Company 2023 Inducement Plan

On January 17, 2023, the Compensation Committee of the Board of Directors (the “Compensation Committee”) of the Company adopted the Scilex Holding Company 2023 Inducement Plan (the “Plan”). The Plan will serve to advance the interests of the Company by providing a material inducement for the best available individuals to join the Company as employees by affording such individuals an opportunity to acquire a proprietary interest in the Company. The Plan provides for the grant of equity-based awards in the form of non-statutory stock options, stock appreciation rights, restricted stock, restricted stock units, and other awards (as set forth under the Plan) solely to prospective employees of the Company or an affiliate of the Company provided that certain criteria are met. The initial maximum number of shares available for grant under the Plan is 1,400,000 shares of the Company’s Common Stock (subject to adjustment for recapitalizations, stock splits, reorganizations and similar transactions).

Amendment to the Yorkville Purchase Agreement

On February 8, 2023, the Company entered into an Amended and Restated Standby Equity Purchase Agreement with Yorkville (the “A&R Yorkville Purchase Agreement”), amending, restating and superseding the Yorkville Purchase Agreement dated November 17, 2022.

Pursuant to the A&R Yorkville Purchase Agreement, the shares of Common Stock, if any, that the Company elects to sell to Yorkville pursuant to a Yorkville Advance will be purchased at a price equal to 98% of the lowest daily volume weighted average price of the Common Stock for any trading day on the date of delivery of a written purchase notice to Yorkville.

Subsequent to December 31, 2022, the Company sold an aggregate of 85,000 shares of Common Stock pursuant to the A&R Yorkville Purchase Agreement for aggregate net proceeds to the Company of approximately $0.6 million.

Elyxyb License

On February 12, 2023, the Company acquired from BioDelivery Sciences International, Inc. (“BSDI”) and Collegium Pharmaceutical, Inc. (“Collegium”, and together with BDSI, the “Collegium Sellers”) the rights to certain patents,

trademarks, regulatory approvals, data, contracts, and other rights related to ELYXYB (celecoxib oral solution) (the “Product”) and its commercialization in the United States and Canada (the “Territory”).

As consideration for the acquisition, the Company assumed various rights and obligations under that certain asset purchase agreement, dated August 3, 2021 (the “DRL APA”), between BDSI and Dr. Reddy’s Laboratories Limited, a company incorporated under the laws of India (“DRL”), including a license from DRL including an irrevocable, royalty-free, exclusive license to know-how and patents of DRL related to the Product and necessary or used to exploit the Product in the Territory. Additionally, under the Purchase Agreement, the Seller granted the Company an irrevocable, royalty-free, exclusive license to know-how related to the Product and necessary or used to exploit the Product in the Territory. No cash consideration was or will be payable to Collegium Sellers for such acquisition; however, the obligations under the DRL APA that were assumed by the Company include obligations to pay royalties for sales of the Product in the Territory for all indications and additional amounts if certain milestones are achieved.

Sorrento Chapter 11 filing

On February 13, 2023, Sorrento, together with its wholly-owned direct subsidiary, Scintilla Pharmaceuticals, Inc., commenced voluntary proceedings under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Southern District of Texas. While the Company is majority-owned by Sorrento, the Company is not a debtor in Sorrento’s voluntary Chapter 11 filing and management does not expect this will impact the Company and will continue to operate its business as usual. As of December 31, 2022, the Company had a $1.8 million receivable from Sorrento, which was fully reserved.

Nature of Operations and Basis of Presentation (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include all adjustments necessary for the fair presentation of the Company’s financial position for the periods presented. The accompanying consolidated financial statements include the accounts of the Company as well as its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of these 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 and disclosure of contingent assets and liabilities at the date of these consolidated financial statements and the reported amounts of expenses during the reporting period. Management believes that these estimates are reasonable; however, actual results may differ from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. The Company minimizes its credit risk associated with cash and cash equivalents by periodically evaluating the credit quality of its primary financial institution. Although the balance at times may exceed federally-insured limits, the Company has not experienced any losses on such accounts.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company follows accounting guidance on fair value measurements for financial instruments measured on a recurring basis, as well as for certain assets and liabilities that are initially recorded at their estimated fair values. Fair value is defined as the exit price, or the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses the following three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs to value its financial instruments: • Level 1: Observable inputs such as unadjusted quoted prices in active markets for identical instruments. • Level 2: Quoted prices for similar instruments that are directly or indirectly observable in the marketplace. • Level 3: Significant unobservable inputs which are supported by little or no market activity and that are financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation. Financial instruments measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires it to make judgments and consider factors specific to the asset or liability. The use of different assumptions and/or estimation methodologies may have a material effect on estimated fair values. Accordingly, the fair value estimates disclosed or initial amounts recorded may not be indicative of the amount that the Company or holders of the instruments could realize in a current market exchange. As of December 31, 2022 and 2021, the carrying amount of cash equivalents approximates their fair value based upon quoted market prices. Certain of the Company’s financial instruments are not measured at fair value on a recurring basis, but are recorded at amounts that approximate their fair value due to their liquid or short-term nature, such as cash, prepaid expenses, accounts receivable, and accounts payable.
Accounts Receivable, Net	Accounts Receivable, Net Accounts receivable are presented net of allowances for expected credit losses and prompt payment discounts. Accounts receivable consists of trade receivables from product sales to customers, which are generally unsecured. Estimated credit losses related to trade accounts receivable are recorded as general and administrative expenses and as an allowance for expected credit losses within accounts receivable, net. The Company reviews reserves and makes adjustments based on historical experience and known collectability issues and disputes. When internal collection efforts on accounts have been exhausted, the accounts are written off by reducing the allowance for expected credit losses.
Inventory	Inventory The Company determines inventory cost on a first-in, first-out basis. The Company reduces the carrying value of inventories to a lower of cost or net realizable value for those items that are potentially excess, obsolete or slow- moving. The Company reserves for excess and obsolete inventory based upon historical experience, sales trends, and specific categories of inventory and expiration dates for on-hand inventory. Inventory costs resulting from these adjustments are recognized as cost of sales in the period in which they are incurred. When future commercialization is considered probable and the future economic benefit is expected to be realized, based on management’s judgment, the Company capitalizes pre-launch inventory costs prior to regulatory approval. As of December 31, 2022 and 2021, the Company’s inventory was primarily comprised of finished goods.
Property and Equipment	Property and Equipment, Net Property and equipment are carried at cost less accumulated depreciation. Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives of the assets, which are generally five to seven years. Leasehold improvements are amortized over the lesser of their estimated useful lives or the term of the respective lease on a straight-line basis. The cost of repairs and maintenance is expensed as incurred.
Acquisitions	Acquisitions The Company accounts for business combinations using the acquisition method of accounting, which requires that assets acquired, including in-process research and development (“IPR&D”) projects and liabilities assumed be recorded at their fair values as of the acquisition date on the Company`s consolidated balance sheets. Any excess of purchase price over the fair value of net assets acquired is recorded as goodwill. The determination of estimated fair value requires the Company to make significant estimates and assumptions. As a result, the Company may record adjustments to the fair values of assets acquired and liabilities assumed within the measurement period (up to one year from the acquisition date) with the corresponding offset to goodwill. Transaction costs associated with business combinations are expensed as they are incurred. When the Company determines net assets acquired do not meet the definition of a business combination under the acquisition method of accounting, the transaction is accounted for as an acquisition of assets and, therefore, no goodwill is recorded and contingent consideration such as payments upon achievement of various developmental, regulatory and commercial milestones generally is not recognized at the acquisition date. In an asset acquisition, up-front payments allocated to IPR&D projects at the acquisition date and subsequent milestone payments are charged to expense in the Company`s consolidated statements of operations unless there is an alternative future use. The Company has acquired and may continue to acquire the rights to develop and commercialize new product candidates. Intangible assets acquired in a business combination that are used for IPR&D activities are considered indefinite-lived until the completion or abandonment of the associated research and development efforts. Upon commercialization of the relevant research and development project, the Company amortizes the acquired IPR&D over its estimated useful life. Capitalized IPR&D is reviewed annually for impairment or more frequently as changes in circumstance or the occurrence of events suggest that the remaining value may not be recoverable.
Contingent Consideration	Contingent Consideration The fair value of contingent consideration liabilities assumed in business combinations is recorded as part of the purchase price consideration of the acquisition, and is determined using a discounted cash flow model or Monte Carlo simulation model. The significant inputs of such models are not observable in the market, such as certain financial metric growth rates, volatility rates, projections associated with applicable milestones, discount rates and the related probabilities and payment structure in the contingent consideration arrangement. Fair value adjustments to contingent consideration liabilities are recorded through operating expenses in the consolidated statement of operations. Other than contingent consideration that is accounted for in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480, Distinguishing Liabilities from Equity, and Topic 815, Derivatives and Hedging, contingent consideration arrangements assumed in an asset acquisition will be measured and accrued when such contingency is resolved.
Goodwill and Other Long-Lived Assets	Goodwill and Other Long-Lived Assets Goodwill, which has an indefinite life, represents the excess cost over fair value of net assets acquired. Goodwill is reviewed for impairment at least annually during the fourth quarter, or more frequently if events occur indicating the potential for impairment. The Company has one reporting unit. During its goodwill impairment review, the Company may assess qualitative factors to determine whether it is more likely than not that the fair value of its reporting unit is less than its carrying amount, including goodwill. The qualitative factors include, but are not limited to, macroeconomic conditions, industry and market considerations, and the overall financial performance of the Company. If, after assessing the totality of these qualitative factors, the Company determines that it is not more likely than not that the fair value of its reporting unit is less than its carrying amount, then no additional assessment is deemed necessary. Otherwise, the Company performs a quantitative goodwill impairment test. The Company may also elect to bypass the qualitative assessment in a period and elect to proceed to perform the quantitative goodwill impairment test. The Company evaluates its long-lived and intangible assets with definite lives, such as property and equipment, patent rights, and acquired technology, for impairment by considering competition by products prescribed for the same indication, the likelihood and estimated future entry of non-generic and generic competition with the same or similar indication and other related factors. The factors that drive the estimate of useful life are often uncertain and are reviewed on a periodic basis or when events occur that warrant review. Recoverability is measured by comparison of the assets’ book value to future net undiscounted cash flows that the assets are expected to generate to determine if a write-down to the recoverable amount is appropriate. If such assets are written down, an impairment will be recognized as the amount by which the book value of the asset group exceeds the recoverable amount.
Public Warrants and Private Placement Warrants	Public Warrants and Private Placement Warrants Upon completion of the Business Combination, the Company assumed public and private placement warrants (“Public Warrants” and “Private Warrants”) that were issued by Vickers in connection with its initial public offering (declared effective by the Securities and Exchange Commission (“SEC”) on January 11, 2021) whereby holders of the public and private placement warrants are entitled to acquire ordinary shares of Vickers. Subsequent to the Business Combination, the Public Warrants were accounted for as equity per FASB ASC Subtopic No. 815-40, Contracts on an Entity’s Own Equity. Warrants classified as equity are recorded at their issuance cost and are not subject to remeasurement at each subsequent balance sheet date. Subsequent to the Business Combination, the Private Warrants were accounted for as liabilities per ASC Subtopic 815-40. The Private Warrants are not considered indexed to the Company’s stock per ASC Subtopic 815-40 as the fair value calculation applicable upon a cashless exercise of a Private Warrant changes based upon the holder of the instrument, which is not an input to a valuation model for a fixed-for-fixed option contract. Therefore, Private Warrants are recognized as derivative liabilities at their estimated fair value on November 10, 2022, the date of the closing of the Business Combination, and are revalued at each subsequent balance sheet date, with fair value changes recognized in the statement of operations. The Company estimates the value of these warrants using a Black-Scholes option pricing formula.
Debt	Debt The Company may enter financing arrangements, the terms of which involve significant assumptions and estimates. This involves estimating future net product sales, determining interest expense, determining the amortization period of the debt discount, as well as determining the classification between current and long-term portions.
Derivative Liabilities	Derivative Liabilities Derivative liabilities are recorded on the Company’s consolidated balance sheets at their fair value on the date of issuance and are revalued on each balance sheet date until such instruments are exercised or expire, with changes in the fair value between reporting periods recorded as other income or expense.
Research and Development Costs	Research and Development Costs The Company expenses the cost of research and development as incurred. Research and development expenses are comprised of costs incurred in performing research and development activities, including clinical trial costs, manufacturing costs for both clinical and preclinical materials as well as other contracted services, license fees and other external costs. Nonrefundable advance payments for goods and services that will be used in future research and development activities are expensed when the activity is performed or when the goods have been received, rather than when payment is made, in accordance with FASB ASC Topic 730, Research and Development.
Income Taxes	Income Taxes The provisions of the FASB ASC Topic 740, Income Taxes, addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under ASC Subtopic 740-10, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The Company has determined that it has uncertain tax positions. The Company accounts for income taxes using the asset and liability method to compute the differences between the tax basis of assets and liabilities and the related financial amounts, using currently enacted tax rates. The Company has deferred tax assets, which are subject to periodic recoverability assessments. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that more likely than not will be realized. As of December 31, 2022 and 2021, the Company maintained a full valuation allowance against its deferred tax assets.
Leases	Leases The Company determines if an arrangement is a lease at inception. Operating lease right-of-use (“ROU”) assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, it uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and is reduced by lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term in selling, general and administrative expenses.
Revenue Recognition	Revenue Recognition The Company’s revenue is generated from product sales within the United States. The Company does not incur significant direct costs to obtain contracts with its customers. Revenue from product sales is fully comprised of sales of ZTlido. The Company’s performance obligation with respect to sales of ZTlido is satisfied at a point in time, when control is transferred upon delivery of product to the customer. The Company considers control to have transferred upon delivery because the customer has legal title to the product, physical possession of the product has been transferred to the customer, the customer has significant risks and rewards of ownership of the product, and the Company has a present right to payment at that time. Invoicing typically occurs upon shipment and the length of time between invoicing and when payment is due is not significant. The aggregate dollar value of unfulfilled orders as of December 31, 2022 and 2021 were not material. Revenues from product sales are recorded net of reserves established for commercial and government rebates, fees and chargebacks, wholesaler and distributor fees, sales returns and prompt payment discounts. Such variable consideration is estimated in the period of the sale and is estimated using a most likely amount approach based primarily upon provisions included in the Company’s customer contract, customary industry practices and current government regulations. Rebates and Chargebacks Rebates are discounts which the Company pays under either government or private health care programs. Government rebate programs include state Medicaid drug rebate programs, the Medicare coverage gap discount programs and the Tricare programs. Commercial rebate and fee programs relate to contractual agreements with commercial healthcare providers, under which the Company pays rebates and fees for access to and position on that provider’s patient drug formulary. Rebates and chargebacks paid under government programs are generally mandated under law, whereas private rebates and fees are generally contractually negotiated by the Company with commercial healthcare providers. Both types of rebates vary over time. The Company records a reduction to gross product sales at the time the customer takes title to the product based on estimates of expected rebate claims. The Company monitors the sales trends and adjusts for these rebates on a regular basis to reflect the most recent rebate experience and contractual obligations. Reserves for rebates and chargebacks are now separately presented as accrued rebates and fees under current liabilities within the Company’s consolidated balance sheet. Prompt Payment Discounts The Company provides its customers with prompt payment discounts which may result in adjustments to the price that is invoiced for the product transferred, in the case that payments are made within a defined period. The prompt payment discount reserve is based on actual gross sales and contractual discount rates. Reserves for prompt payment discounts are included in accounts receivable, net on the consolidated balance sheets. Service Fees The Company compensates its customer and others in the distribution chain for wholesaler and distribution services. The Company has determined such services received to date are not distinct from the Company’s sale of products to the customer and, therefore, these payments have been recorded as a reduction of revenue. Product Returns The Company is obligated to accept the return of products sold that are expiring within six months, damaged or do not meet certain specifications. The Company may authorize the return of products sold in accordance with the term of its sales contracts, and estimates allowances for such amounts at the time of sale. The Company estimates the amount of its product sales that may be returned by its customer and record this estimate as a reduction of revenue in the period the related product revenue is recognized. Co-Payment Assistance Patients who have commercial insurance or pay cash and meet certain eligibility requirements may receive co- payment assistance. The Company accrues for co-payment assistance based on actual program participation and estimates of program redemption using data provided by third-party administrators.
Concentration of Credit Risk	Customer Concentration Risk Prior to April 2, 2022, sales to the Company's sole distributor represented 100% of net revenue. On April 2, 2022, the Company announced the expansion of its direct distribution network to national and regional wholesalers and pharmacies. The distributor continued to provide traditional third-party logistics functions for the Company. The Company had four customers during the year ended December 31, 2022, which individually generated 10% or more of the Company’s total revenue. These customers accounted for 83% of the Company’s revenue for the year ended December 31, 2022, individually ranging between 19% to 24%. As of December 31, 2022, these customers represented 90% of the Company’s outstanding accounts receivable, individually ranging between 24% to 36%. Additionally, during the fiscal years ended December 31, 2022 and 2021, the Company purchased inventory from its sole supplier, Itochu. This exposes the Company to concentration of customer and supplier risk. The Company monitors the financial condition of its customers, limits its credit exposure by setting credit limits, and has not experienced any credit losses for the years ended December 31, 2022, 2021, and 2020.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation in accordance with FASB ASC Topic 718, Compensation – Stock Compensation which establishes accounting for equity instruments exchanged for employee and consulting services. Under such provisions, stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense, under the straight-line method, over the employee’s requisite service period (generally the vesting period of the equity grant) or non-employee’s vesting period. The Company accounts for forfeitures as incurred. For purposes of determining the inputs used in the calculation of stock-based compensation, the Company determines the expected life assumption for options issued using the simplified method, which is an average of the contractual term of the option and its ordinary vesting period since the Company does not have historic exercise behavior. Then the Company determines an estimate of option volatility based on an assessment of historical volatilities of comparable companies whose share prices are publicly available. The Company uses these estimates as variables in the Black-Scholes option pricing model. Depending upon the number of stock options granted, any fluctuations in these calculations could have a material effect on the results presented in our consolidated statement of operations.
Segments	Segments Operating segments are identified as components of an entity where separate discrete financial information is available for evaluation by the chief operating decision maker in making decisions on how to allocate resources and assessing performance. The Company has determined that its chief operating decision maker is its Chief Executive Officer, as he is responsible for making decisions regarding the allocation of resources and assessing performance as well as for strategic operational decisions. The Company is engaged primarily in the development of non-opioid products focused on pain management based on its platform technologies and all sales are based in the United States. Accordingly, the Company has determined that it operates its business as a single reportable segment.
Net Loss per Share	Net Loss per Share Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. Net loss per share has been retrospectively adjusted for all periods presented prior to the Business Combination. Under the two-class method, basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share attributable to common stockholders adjusts basic earnings per share for the potentially dilutive impact of stock options and warrants. As the Company has reported losses for all periods presented, all potentially dilutive securities are antidilutive and accordingly, basic net loss per share equals diluted net loss per share.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an acquirer in a business combination to recognize and measure contract assets and contract liabilities in accordance with ASC Topic 606. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022 and early adoption is permitted. The Company is evaluating the impact the standard will have on its consolidated financial statements.

- Definition

Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.
