Description of Organization Business Operations and Basis of Presentation [Line Items]
Organization and Description of Business Operations	1. Organization and Description of Business Operations Clarus Therapeutics Holdings, Inc. (together with its consolidated subsidiary, the “Company” or “Clarus”) formerly known as Blue Water Acquisition Corp. (“Blue Water”), was incorporated in Delaware on May 22, 2020. Blue Water was a Special Purpose Acquisition Company (“SPAC”) formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. The registration statement for the Company’s Initial Public Offering (“IPO”) was declared effective on December 15, 2020. On December 17, 2020, the Company consummated its IPO of 5,750,000 units (each unit representing a share of common stock and a warrant to purchase a share of common stock (“IPO warrants”)), including 750,000 additional Units to cover over-allotments, at $10.00 per unit, generating gross proceeds of $57.5 million, and incurring offering costs of approximately $3.7 million, of which approximately $2.0 million was for deferred underwriting commissions. Simultaneously with the closing of the IPO, the Company consummated the private placement (“Private Placement”) of 3,445,000 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant to Blue Water Sponsor LLC (the “Sponsor”), generating proceeds of approximately $3.4 million. Upon the closing of the IPO and the Private Placement, approximately $58.7 million ($10.20 per Unit) of the net proceeds of the IPO and certain of the proceeds of the Private Placement was held in a trust account (“Trust Account”) located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and were invested only in U.S. “government securities” within the meaning of Section 2(a)(16) of the U.S. Investment Company Act of 1940, as amended (the “Investment Company Act”) having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 In December 2021, the Company issued and sold 3,024,194 units in a private placement at a purchase price of $4.96 per unit, resulting in net proceeds of $13.8 million, after deducting offering expenses. Each unit consisted of one share of common stock (or one pre-funded Merger On September 9, 2021 (the “Closing Date”), the Company, and Blue Water Merger Sub Corp., a Delaware corporation and wholly-owned subsidiary of the Company (“Merger Sub”), consummated the previously announced merger, pursuant to the Agreement and Plan of Merger, dated as of April 27, 2021 (the “Merger Agreement”), with Clarus Therapeutics, Inc., a Delaware corporation (“Legacy Clarus”), pursuant to which, subject to the terms and conditions set forth in the Merger Agreement, Merger Sub merged with and into Legacy Clarus, with Legacy Clarus surviving as a wholly-owned subsidiary of the Company, and with Legacy Clarus’s equity holders’ and convertible debt holders equity interests converted into the right to receive shares of the Company’s common stock or else be canceled, retired and terminated without consideration, as provided in the Merger Agreement (the “Merger”). Upon the consummation of the business combination, Blue Water changed its name to “Clarus Therapeutics Holdings, Inc.” In connection with the Merger, Legacy Clarus’s convertible noteholders and senior secured noteholders provided $25.0 million in additional capital to Legacy Clarus following the announcement of the execution of the Merger Agreement. All such proceeds plus accrued interest converted to shares of the Company’s common stock at a price of $10.00 per share, resulting in 2,549,939 shares issued on the Closing Date. The additional capital of $25.0 million was received by Legacy Clarus prior to the Closing Date. Together with Blue Water’s cash resources and additional capital, the Company received net proceeds from the Merger (not including the $25.0 million of additional capital) of approximately $17.0 million. At the effective time of the Merger (the “Effective Time”), shares of Legacy Clarus’s Series D redeemable convertible preferred stock (“Series D Preferred Stock”) issued and outstanding and all principal and accrued interest under Legacy Clarus’s convertible notes immediately prior to the Effective Time converted into 13,431,410 shares of the Company’s common stock at a price of $10.20 per share. Additionally, $10.0 million of debt related to Legacy Clarus’ senior secured notes, including certain royalty rights was exchanged for an aggregate of 1,500,000 shares of the Company’s common stock. Further, under a share allocation agreement entered into by Blue Water and Legacy Clarus on September 1, 2021, as part of the Merger, an additional 405,000 shares of the Company’s common stock were allocated to the senior secured noteholders (as further described in Note 3, which included 270,000 shares reallocated to the senior secured note holders from Legacy Clarus’s equity holders and 135,000 shares from the Blue Water founder that were transferred from the Sponsor pursuant to the share allocation agreement. All unexpired, outstanding Series D Warrants of Legacy Clarus remained outstanding and became exercisable for shares of the Company’s common stock, subject to adjustment in accordance with the Merger exchange ratio. All other series of Legacy Clarus preferred stock, common stock and stock options were cancelled and extinguished upon completion of the Merger. In addition, Legacy Clarus’s existing equity incentive plans were terminated. For additional information on the business combination, please refer to Note 3, Business Combination Description of Business Following the Merger The Company operates as a pharmaceutical company post-merger focused on the commercialization of JATENZO ® The Company is subject to risks and uncertainties associated with any pharmaceutical company that is transitioning from the development to commercial stage. Since inception, Legacy Clarus incurred substantial operating losses due to substantial product development and commercialization expenditures. In addition, the Company operates in an environment of rapid technological change and is largely dependent on the services of its employees and consultants. The Company anticipates incurring additional losses until such time, if ever, that it can generate significant sales of JATENZO, is cash flow positive from operations, or enters into cash flow positive business development transactions. The Company’s U.S. patent portfolio on JATENZO currently includes five issued patents and has recently received two notices of allowance from the United States Patent and Trademark Office (USPTO) for claims that cover its oral testosterone replacement product, JATENZO. The issued U.S. patents contain claims to both pharmaceutical compositions and methods of treatment using the Company’s proprietary pharmaceutical composition and all are listed in the FDA Orange Book: Approved Drug Products with Therapeutic Equivalence Evaluations. In addition, the Company has several patent applications pending in the United States and other countries that, if issued, will cover pharmaceutical compositions, methods of treatment and other features of JATENZO, and have the potential to extend patent coverage beyond 2030. Liquidity and Going Concern The Company has evaluated whether there are certain conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. Since its inception, Legacy Clarus has devoted substantially all its efforts to business planning, clinical development, commercial planning and raising capital. Legacy Clarus, and since the Merger, the Company has incurred significant losses from operations since inception and has an accumulated deficit of $321.6 million as of December 31, 2021. Further, as of December 31, 2021, the Company had a working capital deficit of $14.4 million. In addition to the consummation of the Merger and the related investment, the Company plans to seek additional funding through the expansion of its commercial efforts to grow JATENZO and its operating cash flow, business development efforts to out-license Debt If the Company is unable to obtain funding or generate operating cash flow, the Company will be forced to delay, reduce, or eliminate some or all of its product portfolio expansion or commercialization efforts, which could adversely affect its business prospects, or the Company may be unable to continue operations. Although management continues to pursue these plans, there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all. The terms of any financing may adversely affect the holdings or the rights of the Company’s stockholders. Based o 2. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Accordingly, the consolidated financial statements have been prepared on a basis that assumes the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business. Impact of the COVID-19 The business disruptions associated with the ongoing COVID-19 COVID-19 Debt the ongoing COVID-19 The Company is closely monitoring the evolving impact of the pandemic on all aspects of its business. The Company has implemented a number of measures designed to protect the health and safety of its employees, support its customers and promote business continuity. The Company is also actively reviewing and implementing cost-saving measures, including discontinuing or delaying all non-essential COVID-19

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The consolidated financial statements include the accounts and operations of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions are eliminated upon consolidation. As a result of the Merger, the shares and corresponding capital amounts and loss per share related to Legacy Clarus’s outstanding convertible preferred stock and common stock prior to the Merger have been retroactively restated to reflect the actual shares for which the Series D preferred stock converted into because of the conversion terms in the Merger Agreement. For additional information on the Business Combination, please refer to Note 3, Business Combination Reclassification Certain prior period amounts may have been reclassified to conform to the current year presentation. Such reclassifications did not affect reported net income. Segment Information The Company’s chief operating decision maker manages its operations as a single operating segment for the purposes of assessing performance and making operating decisions. All of the Company’s long-lived assets are held in the United States. Use of Estimates Preparation of the 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 the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period covered by the financial statements and accompanying notes. The most significant estimates relate to determination of sales discounts and allowances, fair value of the Company’s common stock and common stock warrants, stock-based compensation, notes, royalty obligation and the valuation of embedded derivatives. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, and records adjustments when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ from those estimates. Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The three levels of inputs that may be used to measure fair value are defined below: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Inputs other than Level 1 inputs that are either directly or indirectly observable, such as quoted market prices, interest rates and yield curves. Level 3: Unobservable inputs for the asset or liability (i.e., supported by little or no market activity). Level 3 inputs include management’s own assumptions about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Cash and Cash Equivalents Cash and cash equivalents represent cash and highly liquid investments with an original contractual maturity at the date of purchase of three months or less. As of December 31, 2021 and 2020, cash and cash equivalents included government-backed money market funds. Concentrations of Risk Substantially all of the Company’s cash and money market funds are held with a single financial institution. Due to its size, the Company believes this financial institution represents minimal credit risk. Deposits in this institution may exceed the amount of insurance provided on such deposits by the Federal Deposit Insurance Corporation for U.S. institutions. The Company has not experienced any losses on its deposits of cash and cash equivalents. Management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. The Company’s accounts receivable balance and revenue recognized is compromised solely from transactions with the Company’s single third-party logistics provider, or 3PL. The Company monitors economic conditions to identify facts or circumstances that may indicate that any of its accounts receivable are at risk of collection. The Company depends on two third-party suppliers for its supply of T-undecanoate Accounts Receivable, Net Accounts receivables are stated at net realizable value. On a periodic basis, management evaluates its accounts receivable and determines whether to provide an allowance or if any accounts should be written off based on a past history of write-offs, collections and current credit conditions. A receivable is considered past due if the Company has not received payments based on agreed-upon terms. The Company generally does not require any security or collateral to support its receivables. The Company performs ongoing evaluations of its customers. The Company has recorded an allowance against its receivables of $0.5 million and $0.2 million as of December 31, 2021, and 2020, respectively. Inventory Inventory is stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out Property and Equipment, net Property and equipment are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets, as follows: Asset Class Estimated Useful Life Computer and office equipment 3 years Furniture and fixtures 7 years Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in loss from operations. Repair and maintenance costs are charged to expense as incurred. Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset group may not be recoverable. There were no charges as a result of impairment losses for the years ended December 31, 2021 or 2020. Deferred Financing Costs The Company capitalizes certain legal, professional accounting and other third-party fees that are directly associated with in-process in-process Derivative warrant liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are liabilities, derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815 Derivatives and Hedging re-assessed The Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period. The fair value of the Private Placement warrants has been estimated using a modified Monte Carlo simulation model at inception and subsequently at each measurement date using the Black-Scholes model. The liabilities are subject to re-measurement The fair value of IPO warrants were initially measured at fair value using a Monte Carlo simulation model and have subsequently been measured based on the listed market price of such warrant. Revenue Recognition In accordance with ASC 606, Revenue from Contracts with Customers Net Product Sales The Company began selling JATENZO in February 2020, in the United States through a 3PL which takes title and control of the goods. The 3PL distributes the product to wholesale distributors (collectively the “Distributors”), with whom the Company has entered into formal agreements for delivery to retail pharmacies. The Company has also entered into arrangements with payors that provide government mandated and/or privately negotiated rebates, chargebacks and discounts for the purchase of the Company’s products. The Company recognizes revenue on sales of JATENZO when the customer obtains control of the product, which occurs at a point in time, typically upon delivery. Product revenues are recorded at the product’s wholesale acquisition costs, net of applicable reserves for variable consideration that are offered within contracts between the Company and its customers, wholesale distributors, payors, and other indirect customers relating to the sale of JATENZO. Components of variable consideration include government and commercial contract rebates, product returns, chargebacks, commercial co-payment The amount of variable consideration which is included in the transaction price may be constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognition under contracts will not occur in a future period. The Company’s analyses contemplate the application of the constraint in accordance with ASC 606. Actual amounts of consideration ultimately received may differ from its estimates. If actual results in the future vary from its estimates, the Company will adjust these estimates, which would affect net product revenue and earnings in the period such variances become known. The below table includes a rollforward of the deferred revenue contract liability balance for the year ended December 31, 2021. Deferred Balance at December 31, 2020 $ 1,172 Amounts deferred 14,370 Revenue recognized (13,957 ) Balance at December 31, 2021 $ 1,585 Cost of Product Sales Cost of product sales include manufacturing and distribution costs, the cost of drug substance, royalties due to third parties on net product sales, freight, shipping, handling, storage costs, salaries of employees involved with production, and a reserve for short-dated, obsolete inventory. The Company began capitalizing inventory upon FDA approval of JANTENZO ® Research and Development Expenses Research and development expenses include salaries and benefits, clinical trials costs, contract services and manufacturing development costs. Research and development expenses are charged to operations as they are incurred. The Company follows the provisions of the Research and Development Topic of the Codification which requires the Company to defer and capitalize nonrefundable advance payments made for goods or services to be used in research and development activities until the goods have been delivered or the related services have been performed. If the goods are no longer expected to be delivered or the services are no longer expected to be performed, the Company would be required to expense the related capitalized advance payments. The Company had no capitalized nonrefundable advance payments and no refundable advance payments as of December 31, 2021 or 2020. The Company is required to estimate its accrued expenses. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on its behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of the Company’s service providers invoice monthly in arrears for services performed or when contractual milestones are met. The Company make estimates of its accrued expenses as of each balance sheet date in its financial statements based on facts and circumstances known at that time. Examples of estimated accrued research and development expenses include fees paid to vendors in connection with preclinical development activities and vendors related to development, manufacturing and distribution of product candidate materials. The Company bases its expenses related to clinical studies on its estimates of the services received and efforts expended pursuant to contracts with multiple vendors that conduct and manage preclinical studies on its behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. In accruing service fees, the Company estimates the time period over which services will be performed and the level of effort to be expended in each period and adjust accordingly. Leases The Company leases office space and recognizes related rent expense on a straight-line basis over the term of the lease. Stock-Based Compensation The Company accounts for all stock-based compensation awards granted as stock-based compensation expense at fair value. The Company’s stock-based payments include stock options and grants of common stock, restricted for vesting conditions. The measurement date for awards is the date of grant, and stock-based compensation costs are recognized as expense over the requisite service period, which is generally the vesting period, on a straight-line basis. Stock-based compensation expense is classified in the accompanying statements of operations based on the function to which the related services are provided. The Company recognizes stock-based compensation expense for the portion of awards that have vested. Forfeitures are recorded as they occur. The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. Patents and Trademarks All patent-related costs incurred in connection with filing and prosecuting patent applications are expensed as incurred due to the uncertainty of the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses in the statement of operations. Basic and Diluted Net Income ( ) Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted-average number of common shares outstanding during the period and, if dilutive, the weighted-average number of potential shares of common stock. Net income (loss) per share attributable to common stockholders is calculated using the two-class as-converted When considering the impact of the convertible equity instruments, diluted net income (loss) per share is computed using the more dilutive of (a) the two-class if-converted Net Loss per Share Comprehensive Loss The Company’s comprehensive loss was the same as its reported net loss for all periods presented. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes deferred tax assets to the extent that it believes that these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step more-likely-than-not The Company recognizes interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying statement of operations. As of December 31, 2021 and 2020, no accrued interest or penalties are included on the related tax liability line in the balance sheet. Emerging Growth Company Status The Company is an “emerging growth company” (“EGC”), as defined in the Jumpstart Our Business Startups Act (“JOBS Act”) and may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not EGCs. The Company may take advantage of these exemptions until it is no longer an EGC under Section 107 of the JOBS Act, which provides that an EGC can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. The Company expects to elect to avail itself of the extended transition period and, therefore, while the Company is an EGC it will not be subject to new or revised accounting standards the same time that they become applicable to other public companies that are not EGCs, unless it chooses to early adopt a new or revised accounting standard.

Business Combination	3. Business Combination On September 9, 2021, the business combination between Blue Water Merger Sub and Legacy Clarus, was consummated, pursuant to the Merger Agreement dated April 27, 2021 (the “Business Combination”). Upon the closing of the Business Combination, Merger Sub merged with and into Legacy Clarus, with Legacy Clarus as the surviving company in the Merger and becoming a wholly-owned subsidiary of the Company. Upon the closing of the Business Combination, Blue Water changed its name to “Clarus Therapeutics Holdings, Inc.” The Business Combination is accounted for as a reverse recapitalization in accordance with U.S. generally accepted accounting principles (“GAAP”). Under this method of accounting, Blue Water is treated as the acquired company and Legacy Clarus is treated as the acquirer for financial statement reporting and accounting purposes. As a result, the historical operations of Legacy Clarus are deemed to be those of the Company. Therefore, the financial statements included in this report reflect (i) the historical operating results of Legacy Clarus prior to the Business Combination; (ii) the combined results of the Blue Water and Legacy Clarus following the Business Combination on September 9, 2021; (iii) the assets and liabilities of Legacy Clarus at their historical cost; and (iv) the Company’s equity structure for all periods presented. The recapitalization of the number of shares of common stock attributable to the Business Combination is reflected retroactively to the earliest period presented and will be utilized for calculating earnings per share in all prior periods presented. No step-up The aggregate consideration issued or reserved for issuance to Legacy Clarus securityholders upon the closing of the Merger was 17,886,348 shares of Company common stock. The 17,886,348 shares includes an aggregate of 1,905,000 shares of common stock (which included the 405,000 shares of the Company’s common stock that were allocated to the senior secured noteholders pursuant to the share allocation agreement, as described in Note 8, of which 270,000 shares reallocated to the senior secured note holders from Legacy Clarus’s equity holders and 135,000 shares from the Blue Water founder that were transferred from the Sponsor), which were issued to the holders of Legacy Clarus’ senior secured notes in connection with the Merger Agreement and were in exchange for $18.6 million of aggregate principal amount of the senior secured notes and certain outstanding royalty rights.

As of December 31, 2021 and 2020, the Company’s cash equivalents consisted of money market funds, classified as Level 1 financial assets, as these assets are valued using quoted market prices in active markets without any valuation adjustment. There were no transfers or reclassifications between Level 1, Level 2 and Level 3 financial assets during the years ended December 31, 2021 and 2020. As of December 31, 2021 and 2020, the Company had Level 3 financial liabilities that were measured at fair value on a recurring basis. The Company’s Warrant Liabilities and Derivative Liability (defined below) are carried at fair value, determined using Level 3 inputs in the fair value hierarchy. As of December 31, 2021 the Warrant Liabilities were valued at $1.6 million, and as of December 31, 2020, the Warrant Liability and Derivative Liability were valued at zero. The carrying amounts reported in the accompanying balance sheets for cash, accounts receivable, accounts payable and accrued expenses approximate their fair value based on the short-term nature of these instruments. The carrying value of long-term and short-term debt, taking into consideration debt discounts and related derivative instruments, is estimated to approximate fair value. Warrant Liabilities In conjunction with a previous loan agreement of Legacy Clarus that was fully paid in 2017, certain lenders were granted warrants (or the “Series D Warrants”), to purchase a total of 183,438 shares of Series D Preferred Stock at an exercise price of $4.50 per share. The expiration date of the warrants is the earlier of July 14, 2021 for 122,292 shares and April 9, 2023 for 61,146 shares, or three years from the effective date of a registration statement for an initial public offering of Legacy Clarus’s stock. At December 31, 2020 the Warrant Liability was valued at zero. During the year ended December 31, 2020, the Company recorded a gain of $0.6 million associated with the change in the fair value of the warrant liability. The Series D Warrants outstanding immediately prior to the Effective Time to purchase 61,146 shares of the Series D Preferred Stock were converted into warrants to purchase 9,246 shares of the Company’s common stock at an exercise price of $29.74 per share and the expiration date remains April 9, 2023. At the Effective Time and immediately following the completion of the Business Combination, 9,195,000 warrants, including 5,750,000 IPO Warrants and 3,445,000 Private Placement warrants, previously issued by Blue Water, were assumed by the Company. Upon consummation of the Merger, the Company concluded that the IPO Warrants are equity classified and the Private Placement Warrants are liability classified in accordance with ASC 815. The Private Placement Warrants are a freestanding financial instrument that requires the Company to transfer equity instruments upon exercise by the warrant holder at a strike price equal to $11.50 per share (the “Private Placement Warrant Liability”). The valuation of the Private Placement Warrant Liability was determined with the assistance of an independent valuation firm that used a modified Monte Carlo simulation model at inception and subsequently at each measurement date using the Black-Scholes model. The fair value was determined using Level 3 inputs. The Private Placement Warrants to purchase common stock are remeasured at each reporting and settlement date. Changes in fair value for each reporting period are recognized in other income (expense) in the statements of operations. A change in the assumptions related to the valuation of the Warrant Liability could have a significant impact on the value of the obligation. The following table sets forth a summary of the assumptions used to estimate the fair value of the Private Placement Warrant Liability at December 31, 2021: Fair value of underlying instrument $ 2.43 Risk-free interest rate 1.22 % Expected term (in years) 4.7 Expected volatility 65.0 % Expected dividend yield — % The following table sets forth a summary of changes in the fair value of the Company’s warrant liability for the year ended December 31, 2021 (in thousands): Beginning warrant liability balance $ — Private placement warrant liability assumed 14,075 Change in fair value of warrant liability (12,508 ) Balance at December 31, 2021 $ 1,567 Derivative Liability From 2016 through 2020, Legacy Clarus entered into convertible notes purchase agreements with related parties for a total aggregate borrowing amount of $81.3 million (see Note 8, Debt non-qualified non-qualified

The Company recorded a gain of approximately $0.3 million during the period ending December 31, 2021 as a result of the extinguishment, representing the difference between the carrying value of the debt exchanged and the value of the shares converted based on the conversion price. The senior secured notes bear interest at 12.5% and specify semiannual payments on March 1 and September 1 and have a maturity date of March 1, 2025.

The value assigned to royalty rights was recorded as a debt discount to the Notes and was amortized to interest expense over the life of the notes. For the years ended December 31, 2021 and 2020 the Company recorded $2.2 million and $2.1 million, respectively, of interest expense associated with the royalty rights. The royalty obligation had a fair value of $7.9 million at issuance in March of 2020. Pursuant to the Merger Agreement and conversion terms, no royalty obligation exists as of December 31, 2021.

Stock-Based Compensation	10. Stock-Based Compensation Clarus Therapeutics Holdings, Inc. 2021 Stock Option and Equity Incentive Plan On August 27, 2021 the Company’s stockholders approved the Clarus Therapeutics Holdings, Inc. 2021 Stock Option and Equity Incentive Plan (the “2021 Plan”). The 2021 Plan provides for the Company to make equity and equity-based incentive awards to officers, employees, directors and consultants. Pursuant to the 2021 Plan, an initial 3,475,000 shares of the Company’s common stock were reserved for issuance (the “Initial Limit”). The 2021 Plan provides that the shares reserved and available for issuance under the 2021 Plan will automatically increase each January 1, beginning on January 1, 2022, by 4% of the outstanding number of shares of common stock on the immediately preceding December 31, or such lesser amount as determined by the plan administrator (the “Annual Increase”). As of December 31, 2021, there were 1,083,550 options and 433,420 restricted stock units granted under the 2021 Plan. There are 1,958,030 shares remaining available for grant under the 2021 Plan at December 31, 2021. Clarus Therapeutics Holdings, Inc. Employee Stock Purchase Plan On August 12, 2021 the Company’s stockholders approved the Clarus Therapeutics Holdings, Inc. Employee Stock Purchase Plan (the “ESPP”). An aggregate of 347,500 shares were reserved and available for issuance under the 2021 ESPP. The 2021 ESPP provides that the number of shares reserved and available for issuance under the plan will automatically increase each January 1, beginning on January 1, 2022, by the lesser of 347,500 shares of the Company’s common stock, 1.0% of the outstanding number of shares of the Company’s common stock on the immediately preceding December 31, or such lesser amount as determined by the ESPP administrator. As of December 31, 2021 the Company had not issued any shares under the ESPP. Stock Options Stock options typically vest over three years and have a maximum term of 10 years. The Company typically grants stock options to employees and non-employees The Company utilized the Black-Scholes option-pricing model to estimate the fair value of stock options awarded to employees. The Black-Scholes option-pricing model requires several key assumptions. The key assumptions used to apply this pricing model were as follows: Year Ended 2021 Risk free interest rate 1.34 % Expected term (in years) 5.95 Expected dividend yield 0 % Expected volatility of underlying common stock 79.76 % The following table summarizes the stock option activity under the 2021 Plan: Stock Options Weighted Average Exercise Price Weighted Average Remaining Contractual (in Years) Intrinsic Value (in thousands) Outstanding January 1, 2021 — $ — — $ — Granted 1,083,550 4.78 9.95 Exercised — Canceled — Outstanding December 31, 2021 1,083,550 $ 4.78 9.95 $ — Options vested or expected to vest as of December 31, 2021 — $ — — $ — Stock options unvested as of December 31, 2021 1,083,550 $ 4.78 9.95 $ — The aggregate intrinsic value of options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common stock for those stock options that had exercise prices lower than the fair value of the common stock as of the end of the reporting period. The weighted average grant-date fair value of stock options granted in 2021 was $3.26 per share. The total fair value of stock options vested during the year ended December 31, 2021 was zero. Restricted Common Stock The Company has granted restricted common stock with service based vesting conditions. Unvested shares of restricted common stock may not be sold or transferred by the holder, except for transfers for estate planning purposes in which the transferee agrees to remain bound by all restrictions set forth in the original common stock purchase agreement. They are legally issued and outstanding but only accounted for as outstanding when vested. These restrictions lapse over the three Number of Shares Weighted Average Grant Date Fair Value Unvested restricted stock as of January 1, 2021 — $ — Granted 433,420 $ 4.78 Unvested restricted stock as of December 31, 2021 433,420 $ 4.78 The aggregate fair value of restricted stock awards that vested during the year ended December 31, 2021 was zero. Legacy Clarus Stock Option and Incentive Plan Legacy Clarus previously maintained various stock option and incentive plans and awarded options under such plans. Upon completion of the Business Combination, all such plans were terminated, and all options issued and outstanding, whether vested or unvested, were cancelled and extinguished. As a result, the Company recognized approximately $0.2 million of previously unrecognized stock-based compensation expense related to unvested stock options under the plans during the period ended December 31, 2021. Stock-Based Compensation Expense Stock-based compensation expense, including expense associated with the Legacy Clarus incentive plans up until the date of the business combination ($559 in 2021 and $825 in 2020), is as follows (in thousands): Years Ended December 31, 2021 2020 Selling and marketing $ 43 $ 183 Research and development 60 189 General and administrative 565 453 Total stock-based compensation expense $ 668 $ 825 As of December 31, 2021, there was $5.5 million of unrecognized stock-based compensation expense related to unvested stock options and restricted common stock, which is estimated to be recognized over a period of 3.70 years.

Income Taxes	11. Income Taxes No provision for federal or state income taxes was recorded during the years ended December 31, 2021 and 2020, as the Company incurred operating losses and maintains a full valuation allowance against its net deferred tax assets. The reported amount of income tax benefit for the years ended December 31, 2021 and 2020 differs from the amount that would result from applying the domestic federal statutory rates to pretax losses primarily because of changes in the valuation allowance, state taxes, and the generation of research and development credits. A reconciliation of the Company’s statutory income tax rate to the Company’s effective income tax rate is as follows (in thousands): Year Ended December 31, 2021 2020 Income at U.S. statutory rate $ (8,530 ) 21.00 % $ 912 21.00 % State taxes, net of federal benefit (2,578 ) 6.35 % (1,583 ) -36.45 % Change in fair value (2,627 ) 6.47 % (14,047 ) -323.39 % Interest Expense 1,077 -2.65 % 1,410 32.46 % Stock compensation 70 -0.17 % 127 2.93 % Transaction costs (664 ) 1.64 % — 0.00 % Permanent differences and other 1 0.00 % 6 0.13 % Valuation allowance 13,251 -32.62 % 13,175 303.32 % — 0.00 % — 0.00 % The net deferred income tax asset balance related to the following: Years Ended December 31, 2021 2020 Deferred tax assets Stock compensation $ 10 $ 64 Accruals and other 6,507 4,151 Debt discount 597 483 Royalty liability — 2,272 Net operating loss carryforwards 62,606 51,981 Tax credits 6,731 6,774 Total deferred tax assets 76,451 65,662 Less: valuation allowance (76,451 ) (65,662 ) Deferred tax assets, net $ — $ — At December 31, 2021, the Company had approximately $231.7 million and $202.7 million of federal and state net operating loss (“ NOL Future realization of the tax benefits of existing temporary differences and net operating loss carryforwards ultimately depends on the existence of sufficient taxable income within the carryforward period. As of December 31, 2021 and 2020, the Company performed an evaluation to determine whether a valuation allowance was needed. The Company considered all available evidence, both positive and negative, which included the results of operations for the current and preceding years. The Company determined that it was not possible to reasonably quantify future taxable income and determined that it is more likely than not that all of the deferred tax assets will not be realized. Accordingly, the Company maintained a full valuation allowance as of December 31, 2021 and 2020. The Company’s valuation allowance for the year ended December 31, 2021 and 2020 is as follows: Years Ended December 31, 2021 2020 Valuation allowance at beginning of year $ 65,662 $ 52,487 Increases recorded due to income tax provisions 13,251 13,175 Decreases recorded to equity (2,462 ) — Valuation allowance at end of year $ 76,451 $ 65,662 Under Internal Revenue Code Section 382, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change pre-change The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations for both federal taxes and the many states in which we operate or do business in. ASC 740 states that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits. The Company records uncertain tax positions as liabilities in accordance with ASC 740 and adjust these liabilities when its judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from the Company’s current estimate of the unrecognized tax benefit liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information is available. As of December 31, 2020 and 2021 the Company has not recorded any uncertain tax positions in its financial statements. The Company recognizes interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying consolidated statement of operations. As of December 31, 2021 and 2020, no accrued interest or penalties are included on the related tax liability line in the consolidated balance sheet. The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Company is subject to examination by federal and state jurisdictions, where applicable. The earliest tax years that remain subject to examination by jurisdiction is 2018 for both federal and state. However, to the extent the Company utilizes net operating losses from years prior to 2018, the statute remains open to the extent of the net operating losses or other credits are utilized. The resolution of tax matters is not expected to have a material effect on the Company’s financial statements.

On April 2, 2019, an action for patent infringement was filed against Legacy Clarus by Lipocine in the U.S. District Court for the District of Delaware. The lawsuit (Civil Action No. 19-cv-622, pre-judgment Legacy Clarus asserted defenses of noninfringement and invalidity under 35 U.S.C. §§ 103 and 112, and asserted counterclaims of inequitable conduct, patent misuse and exceptional case. Legacy Clarus’s motion for summary judgment of invalidity under Section 112 was argued on January 15, 2021, and was granted on May 25, 2021, the decision finding all asserted claims invalid for failure to satisfy the written description requirement. On June 15, 2021, Legacy Clarus requested the Court to schedule a bench trial on Legacy Clarus’s counterclaims of inequitable conduct, patent misuse, and exceptional case at the earliest practicable date, pursuant to the Court’s invitation to make such a request. In July 2021, Legacy Clarus and Lipocine entered into a settlement agreement that settled all claims between the parties, including a pending interference matter (No. 106,128) and the pending Legacy Clarus counterclaims against Lipocine, and provided for a payment by Lipocine to Legacy Clarus of a $4.0 million settlement fee payable as follows: $2.5 million upfront, $1.0 million within 12 months, and the remainder within two years. The Company is recognizing the payments in income as they are received. The Company received payment of $2.5 million of the $4.0 million in July 2021, which is recorded within the litigation settlement line in other income and expense on the statement of operations.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The consolidated financial statements include the accounts and operations of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions are eliminated upon consolidation. As a result of the Merger, the shares and corresponding capital amounts and loss per share related to Legacy Clarus’s outstanding convertible preferred stock and common stock prior to the Merger have been retroactively restated to reflect the actual shares for which the Series D preferred stock converted into because of the conversion terms in the Merger Agreement. For additional information on the Business Combination, please refer to Note 3, Business Combination
Reclassification	Reclassification Certain prior period amounts may have been reclassified to conform to the current year presentation. Such reclassifications did not affect reported net income.
Segment Information	Segment Information The Company’s chief operating decision maker manages its operations as a single operating segment for the purposes of assessing performance and making operating decisions. All of the Company’s long-lived assets are held in the United States.
Use of Estimates	Use of Estimates Preparation of the 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 the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period covered by the financial statements and accompanying notes. The most significant estimates relate to determination of sales discounts and allowances, fair value of the Company’s common stock and common stock warrants, stock-based compensation, notes, royalty obligation and the valuation of embedded derivatives. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, and records adjustments when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ from those estimates.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The three levels of inputs that may be used to measure fair value are defined below: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Inputs other than Level 1 inputs that are either directly or indirectly observable, such as quoted market prices, interest rates and yield curves. Level 3: Unobservable inputs for the asset or liability (i.e., supported by little or no market activity). Level 3 inputs include management’s own assumptions about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents represent cash and highly liquid investments with an original contractual maturity at the date of purchase of three months or less. As of December 31, 2021 and 2020, cash and cash equivalents included government-backed money market funds.
Concentration of Credit Risk	Concentrations of Risk Substantially all of the Company’s cash and money market funds are held with a single financial institution. Due to its size, the Company believes this financial institution represents minimal credit risk. Deposits in this institution may exceed the amount of insurance provided on such deposits by the Federal Deposit Insurance Corporation for U.S. institutions. The Company has not experienced any losses on its deposits of cash and cash equivalents. Management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. The Company’s accounts receivable balance and revenue recognized is compromised solely from transactions with the Company’s single third-party logistics provider, or 3PL. The Company monitors economic conditions to identify facts or circumstances that may indicate that any of its accounts receivable are at risk of collection. The Company depends on two third-party suppliers for its supply of T-undecanoate
Accounts Receivable, Net	Accounts Receivable, Net Accounts receivables are stated at net realizable value. On a periodic basis, management evaluates its accounts receivable and determines whether to provide an allowance or if any accounts should be written off based on a past history of write-offs, collections and current credit conditions. A receivable is considered past due if the Company has not received payments based on agreed-upon terms. The Company generally does not require any security or collateral to support its receivables. The Company performs ongoing evaluations of its customers. The Company has recorded an allowance against its receivables of $0.5 million and $0.2 million as of December 31, 2021, and 2020, respectively.
Inventory	Inventory Inventory is stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out
Property and Equipment, net	Property and Equipment, net Property and equipment are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets, as follows: Asset Class Estimated Useful Life Computer and office equipment 3 years Furniture and fixtures 7 years Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in loss from operations. Repair and maintenance costs are charged to expense as incurred.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset group may not be recoverable. There were no charges as a result of impairment losses for the years ended December 31, 2021 or 2020.
Deferred Financing Costs	Deferred Financing Costs The Company capitalizes certain legal, professional accounting and other third-party fees that are directly associated with in-process in-process
Derivative warrant liabilities	Derivative warrant liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are liabilities, derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815 Derivatives and Hedging re-assessed The Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period. The fair value of the Private Placement warrants has been estimated using a modified Monte Carlo simulation model at inception and subsequently at each measurement date using the Black-Scholes model.

Revenue Recognition	Revenue Recognition In accordance with ASC 606, Revenue from Contracts with Customers Net Product Sales The Company began selling JATENZO in February 2020, in the United States through a 3PL which takes title and control of the goods. The 3PL distributes the product to wholesale distributors (collectively the “Distributors”), with whom the Company has entered into formal agreements for delivery to retail pharmacies. The Company has also entered into arrangements with payors that provide government mandated and/or privately negotiated rebates, chargebacks and discounts for the purchase of the Company’s products. The Company recognizes revenue on sales of JATENZO when the customer obtains control of the product, which occurs at a point in time, typically upon delivery. Product revenues are recorded at the product’s wholesale acquisition costs, net of applicable reserves for variable consideration that are offered within contracts between the Company and its customers, wholesale distributors, payors, and other indirect customers relating to the sale of JATENZO. Components of variable consideration include government and commercial contract rebates, product returns, chargebacks, commercial co-payment The amount of variable consideration which is included in the transaction price may be constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognition under contracts will not occur in a future period. The Company’s analyses contemplate the application of the constraint in accordance with ASC 606. Actual amounts of consideration ultimately received may differ from its estimates. If actual results in the future vary from its estimates, the Company will adjust these estimates, which would affect net product revenue and earnings in the period such variances become known. The below table includes a rollforward of the deferred revenue contract liability balance for the year ended December 31, 2021. Deferred Balance at December 31, 2020 $ 1,172 Amounts deferred 14,370 Revenue recognized (13,957 ) Balance at December 31, 2021 $ 1,585
Cost of Product Sales	Cost of Product Sales Cost of product sales include manufacturing and distribution costs, the cost of drug substance, royalties due to third parties on net product sales, freight, shipping, handling, storage costs, salaries of employees involved with production, and a reserve for short-dated, obsolete inventory. The Company began capitalizing inventory upon FDA approval of JANTENZO ®
Research and Development Expenses	Research and Development Expenses Research and development expenses include salaries and benefits, clinical trials costs, contract services and manufacturing development costs. Research and development expenses are charged to operations as they are incurred. The Company follows the provisions of the Research and Development Topic of the Codification which requires the Company to defer and capitalize nonrefundable advance payments made for goods or services to be used in research and development activities until the goods have been delivered or the related services have been performed. If the goods are no longer expected to be delivered or the services are no longer expected to be performed, the Company would be required to expense the related capitalized advance payments. The Company had no capitalized nonrefundable advance payments and no refundable advance payments as of December 31, 2021 or 2020. The Company is required to estimate its accrued expenses. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on its behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of the Company’s service providers invoice monthly in arrears for services performed or when contractual milestones are met. The Company make estimates of its accrued expenses as of each balance sheet date in its financial statements based on facts and circumstances known at that time. Examples of estimated accrued research and development expenses include fees paid to vendors in connection with preclinical development activities and vendors related to development, manufacturing and distribution of product candidate materials. The Company bases its expenses related to clinical studies on its estimates of the services received and efforts expended pursuant to contracts with multiple vendors that conduct and manage preclinical studies on its behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. In accruing service fees, the Company estimates the time period over which services will be performed and the level of effort to be expended in each period and adjust accordingly.
Leases	Leases The Company leases office space and recognizes related rent expense on a straight-line basis over the term of the lease.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for all stock-based compensation awards granted as stock-based compensation expense at fair value. The Company’s stock-based payments include stock options and grants of common stock, restricted for vesting conditions. The measurement date for awards is the date of grant, and stock-based compensation costs are recognized as expense over the requisite service period, which is generally the vesting period, on a straight-line basis. Stock-based compensation expense is classified in the accompanying statements of operations based on the function to which the related services are provided. The Company recognizes stock-based compensation expense for the portion of awards that have vested. Forfeitures are recorded as they occur. The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model.
Patents and Trademarks	Patents and Trademarks All patent-related costs incurred in connection with filing and prosecuting patent applications are expensed as incurred due to the uncertainty of the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses in the statement of operations.
Basic and Diluted Net Income (Loss) per Share	Basic and Diluted Net Income ( ) Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted-average number of common shares outstanding during the period and, if dilutive, the weighted-average number of potential shares of common stock. Net income (loss) per share attributable to common stockholders is calculated using the two-class as-converted When considering the impact of the convertible equity instruments, diluted net income (loss) per share is computed using the more dilutive of (a) the two-class if-converted Net Loss per Share
Comprehensive Loss	Comprehensive Loss The Company’s comprehensive loss was the same as its reported net loss for all periods presented.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes deferred tax assets to the extent that it believes that these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step more-likely-than-not The Company recognizes interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying statement of operations. As of December 31, 2021 and 2020, no accrued interest or penalties are included on the related tax liability line in the balance sheet.
Emerging Growth Company Status	Emerging Growth Company Status The Company is an “emerging growth company” (“EGC”), as defined in the Jumpstart Our Business Startups Act (“JOBS Act”) and may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not EGCs. The Company may take advantage of these exemptions until it is no longer an EGC under Section 107 of the JOBS Act, which provides that an EGC can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. The Company expects to elect to avail itself of the extended transition period and, therefore, while the Company is an EGC it will not be subject to new or revised accounting standards the same time that they become applicable to other public companies that are not EGCs, unless it chooses to early adopt a new or revised accounting standard.

(2) The effect of the convertible notes on the numerator for the year ended December 31, 2020 relates to the impact that the convertible notes had on net income during the period and are removed from net income when calculating net income (loss) attributable to common stockholders diluted using the if-converted method. The effect of the convertible notes on the shares in the denominator for the year ended December 31, 2020 was calculated based on the carrying value of the convertible notes balance at December 31, 2020, converted at the series D price of $4.50 per share and further retroactively adjusted for the effect of the Business Combination and are added back to the denominator when calculating diluted EPS using the if-converted method. These are excluded from the computation of diluted net loss per share attributable to common stockholders as of December 31, 2021 because including them would have had an anti-dilutive effect. The effect of accretion of preferred stock is $0 in 2021 because of the effect of the reversal of previous accretion forgone by the preferred shareholders upon completion of the Business Combination provided no benefit to the holders of the cancelled Legacy Clarus common stock.

Net loss per common share attributable to common stockholders, diluted		$ (5.72)	$ (8.20)
[1]	The effect of accretion of preferred stock is $0 in 2021 because of the effect of the reversal of previous accretion forgone by the preferred shareholders upon completion of the Business Combination provided no benefit to the holders of the canceled Legacy Clarus common stock.
[2]	The gain on extinguishment of convertible notes relates to the difference between the carrying value of the convertible notes upon conversion to shares and the fair value of the shares exchanged which requires adjustment to the numerator when calculating basic EPS.
[3]	The effect of the convertible notes on the numerator for the year ended December 31, 2020 relates to the impact that the convertible notes had on net income during the period and are removed from net income when calculating net income (loss) attributable to common stockholders diluted using the if-converted method. The effect of the convertible notes on the shares in the denominator for the year ended December 31, 2020 was calculated based on the carrying value of the convertible notes balance at December 31, 2020, converted at the series D price of $4.50 per share and further retroactively adjusted for the effect of the Business Combination and are added back to the denominator when calculating diluted EPS using the if-converted method. These are excluded from the computation of diluted net loss per share attributable to common stockholders as of December 31, 2021 because including them would have had an anti-dilutive effect.
