Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of the Organization and Business	NOTE 1 — NATURE OF THE ORGANIZATION AND BUSINESS Unless the context requires otherwise, references to “Carmell,” or the “Company” prior to the closing of the Business Combination (as defined below), are intended to refer to Carmell Therapeutics Corporation, a Delaware corporation, (“Legacy Carmell”), and, after the closing of the Business Combination, are intended to refer to Carmell Corporation, a Delaware corporation, and its consolidated subsidiaries. Carmell Corporation is a bio-aesthetics company developing cosmetic skincare and haircare products that utilize the human platelet secretome to topically deliver proteins and growth factors to support skin and hair health. The Company’s product pipeline also includes innovative bone and wound healing products that are under development. Carmell’s operations are based in Pittsburgh, Pennsylvania. The Company operates as a single segment, and all of its operations are located in the United States. Carmell’s common stock, par value $ 0.0001 per share (the “Common Stock”), and Redeemable Warrants, each whole warrant exercisable for one share of Common Stock at an exercise price of $ 11.50 (the “Public Warrants”), trade on The Nasdaq Capital Market under the ticker symbols “CTCX” and “CTCXW”, respectively. Business Combination On July 14, 2023 (the “Closing Date”), the Company consummated a business combination (the “Business Combination”) pursuant to the terms of the Business Combination Agreement, dated as of January 4, 2023 (the “Business Combination Agreement”), by and among Alpha Healthcare Acquisition Corp. III, a Delaware corporation and the predecessor of Carmell (“Alpha”), Candy Merger Sub, Inc., a Delaware corporation (“Merger Sub”) and Legacy Carmell, pursuant to which Merger Sub merged with and into Legacy Carmell, with Legacy Carmell as the surviving company of the Business Combination. After giving effect to the Business Combination, Legacy Carmell became a wholly owned subsidiary of the Company. Pursuant to the Business Combination Agreement, on the Closing Date, Alpha changed its name to “Carmell Therapeutics Corporation” and Legacy Carmell changed its name to “Carmell Regen Med Corporation.” On August 1, 2023, the Company filed an amendment to its Third Amended and Restated Certificate of Incorporation with the Delaware Secretary of State to change its name to “Carmell Corporation.” Pursuant to the Business Combination Agreement, at the effective time of the Business Combination (the “Effective Time”), (i) each outstanding share of common stock of Legacy Carmell (the “Legacy Carmell common stock”) was converted into the right to receive a number of shares of Common Stock equal to the applicable Exchange Ratio (as defined below); (ii) each outstanding share of preferred stock of Legacy Carmell was converted into the right to receive the aggregate number of shares of Common Stock that would be issued upon conversion of the underlying Legacy Carmell common stock, multiplied by the applicable Exchange Ratio; (iii) each outstanding option and warrant to purchase Legacy Carmell common stock was converted into an option or warrant, as applicable, to purchase a number of shares of Common Stock equal to the number of shares of Legacy Carmell common stock subject to such option or warrant multiplied by the applicable Exchange Ratio; and (iv) each outstanding share of Alpha Class A common stock, par value $ 0.0001 per share (“Class A Common Stock”), and each share of Alpha Class B common stock, par value $ 0.0001 per share (“Class B Common Stock”), was converted into one share of Common Stock. As of the Closing Date, the Exchange Ratio with respect to Legacy Carmell common stock was 0.06154 and the Exchange Ratio with respect to each outstanding derivative equity security of Legacy Carmell was between 0.06684 and 0.10070 . On July 11, 2023, the record date for the special meeting of Alpha’s stockholders to approve the Business Combination (the “Special Meeting”), there were (i) 15,444,103 shares of Class A Common Stock issued and outstanding and (ii) 3,861,026 shares of Class B Common Stock issued and outstanding and held by AHAC Sponsor III LLC, Alpha’s sponsor (the “Sponsor”). In addition, on the closing date of Alpha’s initial public offering (the “IPO”), Alpha had issued 455,000 warrants to purchase Class A Common Stock to the Sponsor in a private placement. Prior to the Special Meeting, holders of 12,586,223 shares of Alpha Class A Common Stock included in the units issued in Alpha’s IPO (excluding 1,705,959 shares of the Class A Common Stock purchased by Meteora (as defined below) directly from the redeeming stockholders under the Forward Purchase Agreement (as defined below)) exercised their right to redeem such shares for cash at a price of approximately $ 10.28 per share (net of the withholding for federal and franchise tax liabilities), for an aggregate redemption price of approximately $ 29,374,372 . The redemption price was paid out of Alpha’s trust account, which, after taking into account the redemptions but before any transaction expense, had a balance of $ 29,376,282 at the Closing Date. The Business Combination was accounted for as a reverse recapitalization in accordance with accounting principles generally accepted in the United States (“GAAP”), and under this method of accounting, Alpha was treated as the acquired company for financial reporting purposes, and Legacy Carmell was treated as the accounting acquirer. Operations prior to the Business Combination are those of Legacy Carmell. Unless otherwise noted, the Company has retroactively adjusted all common and preferred share and related share price information to give effect to the Exchange Ratio established in the Business Combination Agreement. Forward Purchase Agreement On July 9, 2023, Alpha and each of Meteora Special Opportunity Fund I, LP (“MSOF”), Meteora Capital Partners, LP (“MCP”) and Meteora Select Trading Opportunities Master, LP (“MSTO”) (with MCP, MSOF, and MSTO collectively as the “Sellers” or “Meteora”) entered into a forward purchase agreement (the “Forward Purchase Agreement”) providing for an over-the-counter equity forward transaction relating to, prior to the Effective Time, the Class A Common Stock and, after the Effective Time, the Common Stock. Pursuant to the terms of the Forward Purchase Agreement, at the closing of the Business Combination, the Sellers purchased directly from the stockholders of Alpha 1,705,959 shares of Class A Common Stock (the “Recycled Shares”) at a price of $ 10.28 per share (the “Initial Price”), which is the price equal to the redemption price at which holders of Class A Common Stock were permitted to redeem their shares in connection with the Business Combination pursuant to Section 9.2(a) of Alpha’s Second Amended and Restated Certificate of Incorporation, as amended (the “Second Amended Charter”). In accordance with the terms of the Forward Purchase Agreement, at the Closing Date, the Company paid to the Sellers an aggregate cash amount of $ 17,535,632 , which was equal to the product of (a) the Recycled Shares and (b) the Initial Price. The settlement date will be the earliest to occur of (a) the first anniversary of the Closing Date and (b) after the occurrence of (i) a Delisting Event (as defined in the Forward Purchase Agreement) or (ii) a Registration Failure (as defined in the Forward Purchase Agreement), upon the date specified by Meteora in a written notice delivered to the Company at Meteora’s discretion (which settlement date shall not be earlier than the date of such notice). Any Recycled Shares not sold in accordance with the early termination provisions described below will incur a $ 0.50 per share termination fee payable by the Company to Meteora at settlement. From time to time and on any date following the Business Combination (any such date, an “OET Date”) and subject to the terms and conditions below, Meteora may, in its absolute discretion, and so long as the daily volume-weighted average price (“VWAP Price”) of the Recycled Shares is equal to or exceeds the Reset Price (as defined in the Forward Purchase Agreement), terminate the transaction in whole or in part by providing written notice (an “OET Notice”) in accordance with the terms of the Forward Purchase Agreement. The effect of an OET Notice given shall be to reduce the number of shares by the number of Terminated Shares (as defined in the Forward Purchase Agreement) specified in such OET Notice with effect as of the related OET Date. As of each OET Date, the Company shall be entitled to an amount from Meteora, and Meteora shall pay to the Company an amount equal to the product of (a) the number of Terminated Shares multiplied by (b) the Initial Price in respect of such OET Date. The Reset Price is initially $ 11.50 and subject to a $ 11.50 floor (the “Reset Price Floor”). The Reset Price will be adjusted on the first scheduled trading day of every week commencing with the first week following the seventh day after the closing of the Business Combination to be the lowest of (a) the then-current Reset Price, and (b) the prior week VWAP Price of the shares of Common Stock; provided that the Reset Price shall be no lower than the Reset Price Floor. On July 9, 2023, in connection with the Forward Purchase Agreement, the Sellers entered into a Non-Redemption Agreement with the Company, pursuant to which the Sellers agreed not to exercise redemption rights under the Second Amended Charter with respect to an aggregate of 100,000 shares of Common Stock. Axolotl Biologix Acquisition On August 9, 2023 (the “Merger Closing Date”), the Company completed the acquisition of Axolotl Biologix, Inc. (“AxoBio”) pursuant to an Agreement and Plan of Merger, dated July 26, 2023 (as amended, the “Merger Agreement”), by and among the Company, AxoBio, Aztec Merger Sub, Inc., a wholly owned subsidiary of the Company (“Merger Sub I”), and Axolotl Biologix LLC, a wholly owned subsidiary of the Company (“Merger Sub II”). Upon the closing of the transactions contemplated by the Merger Agreement (the “Merger Closing”), (a) Merger Sub I merged with and into AxoBio, after which the separate corporate existence of Merger Sub I ceased, and AxoBio continued as the surviving corporation, and (b) AxoBio merged with and into Merger Sub II, after which AxoBio ceased to exist, and Merger Sub II survived as a wholly owned subsidiary of the Company (collectively, the “AxoBio Acquisition”). At the effective time of the AxoBio Acquisition (the “Merger Effective Time”), each share of AxoBio’s common stock, par value $ 0.001 per share (“AxoBio Common Stock”), (other than Dissenting Shares (as defined in the Merger Agreement) and shares held as treasury stock) issued and outstanding as of immediately prior to the Merger Effective Time was canceled and converted into the right to receive a pro rata share of: • $ 8,000,000 in cash (the “Closing Cash Consideration”), payable upon delivery of AxoBio’s audited financial statements; • 3,845,337 shares of Common Stock and 4,243 shares of a newly designated series of Series A Convertible Voting Preferred Stock (the “Series A Preferred Stock”) issued upon the Merger Closing Date (the “Closing Share Consideration”); and • up to $ 9,000,000 in cash and up to $ 66,000,000 in shares of Common Stock that, in each case, were subject to the achievement of certain revenue targets and research and development milestones (the “Earnout”). Axolotl Biologix Disposition On March 20, 2024, the Company entered into a Membership Interest Purchase Agreement (the “Purchase Agreement”) with the former stockholders of AxoBio, including Burns Ventures, LLC, a Texas limited liability company (“BVLLC”), H. Rodney Burns, an individual resident of Texas (“Burns”), AXO XP, LLC, an Arizona limited liability company (“AXPLLC”), and Protein Genomics, LLC, a Delaware corporation (“PGEN” and together with BVLLC, Burns, and AXPLLC, collectively, the “Buyers” and each, a “Buyer”), providing for, upon the terms and subject to the conditions set forth therein, the sale by the Company of all outstanding limited liability company interests of AxoBio (the “AxoBio Disposition”) to the Buyers for aggregate consideration as described below. The AxoBio Disposition closed on March 26, 2024 . The consideration for the AxoBio Disposition consisted of (i) the Closing Share Consideration, initially issued as consideration to the Buyers under the Merger Agreement, (ii) cancellation of the notes payable to the Buyers in an aggregate principal amount of $ 8,000,000 issued as the Closing Cash Consideration in the AxoBio Acquisition and (iii) termination of the Company’s obligations with respect to the Earnout. Risks and Uncertainties Disruption of global financial markets and a recession or market correction, including the ongoing military conflicts between Russia and Ukraine and the related sanctions imposed against Russia, as well as the conflict between Israel and Hamas, the ongoing effects of the COVID-19 pandemic, and other global macroeconomic factors such as inflation and rising interest rates, could reduce the Company’s ability to access capital, which could in the future negatively affect the Company’s liquidity and could materially affect the Company’s business and the value of its common stock.

Summary of Significant Accounting Policies	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These financial statements should be read in conjunction with the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. The accompanying unaudited condensed consolidated financial statements include all adjustments that are of a normal recurring nature and necessary for the fair presentation of the results for the interim periods presented. Results for interim periods are not necessarily indicative of results to be expected for the full year. Emerging Growth Company Status The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (the “Securities Act”), as modified by the Jumpstart our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates in these financial statements include those related to the forward purchase asset, earnout liabilities, derivative liabilities, long-term assets and goodwill impairment, the provision or benefit for income taxes and the corresponding valuation allowance on deferred tax assets, and contingent liabilities. If the underlying estimates and assumptions upon which the financial statements are based change in the future, actual amounts may differ from those included in the accompanying financial statements. Business Combinations The Company allocates the fair value of the purchase consideration of its acquisitions to the tangible assets, liabilities, and intangible assets acquired based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Acquisition-related expenses are expensed as incurred and included in general and administrative expenses. The allocation of the purchase price requires management to make significant estimates in determining the fair values of assets acquired and liabilities assumed, especially with respect to intangible assets. These estimates are based on information obtained from management of the acquired companies and historical experience. These estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable, and if different estimates were used, the purchase price for the acquisition could be allocated to the acquired assets and liabilities differently from the allocation that the Company has made. Discontinued Operations On March 26, 2024, the Company completed the AxoBio Disposition as described in Note 1 above. In accordance with Financial Accounting Standards Board Accounting Standards Codification (“ASC”) 205, Presentation of Financial Statements, Discontinued Operations, Other Presentation Matters (“ASC 205”) , the assets and liabilities of AxoBio are classified as available for sale on the accompanying unaudited condensed consolidated balance sheets, and the results of its operations are reported as discontinued operations in the accompanying unaudited condensed consolidated statements of operations. Segment Reporting ASC Topic No. 280, Segment Reporting (“ASC 280”), establishes standards for the way that public business enterprises report information about operating segments in their annual consolidated financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. ASC 280 also establishes standards for related disclosures about products and services, geographic areas and major customers. The Company’s business segments are based on the organizational structure used by the chief operating decision maker to make operating and investment decisions and assess performance. Our chief executive officer, who is our chief operating decision maker, views the Company’s operations and manages its business in one operating segment, which is the business of developing and commercializing aesthetic and regenerative care products. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents are held by financial institutions and are federally insured up to certain limits. At times, the Company’s cash and cash equivalents balance exceeds the federally insured limits, which potentially subject the Company to concentrations of credit risk. For the three months ended March 31, 2024 and 2023, the Company has experienced no losses related to its cash and cash equivalents that exceed federally insured deposit limits. As of March 31, 2024, the Company had cash in excess of federally insured limits of $ 392,161 . As of March 31, 2024 and December 31, 2023, the Company had cash equivalents of $ 15,107 and $ 30,000 , respectively. Cash equivalents as of December 31, 2023 are classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheets. Accounts Receivables, Net Accounts receivable are recorded at the original invoice amount. Receivables are considered past due based on the contractual payment terms. The Company reserves a percentage of its trade receivable balance based on collection history and current economic trends that it expects will impact the level of credit losses over the life of the Company’s receivables. These reserves are re-evaluated on a regular basis and adjusted as needed. Once a receivable is deemed to be uncollectible, such balance is charged against the reserve. The Company had no reserve related to the potential likelihood of not collecting its receivables as of March 31, 2024 and December 31, 2023. All of the Company’ s trade receivables were related to AxoBio at December 31, 2023 and classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheets. Inventories The Company’s inventory consists of finished goods and is stated at the lower of cost or net realizable value. Cost is calculated by applying the first-in-first-out method. The Company regularly reviews inventory quantities on hand and writes down to its net realizable value any inventory that it believes to be impaired. Management considers forecast demand in relation to the inventory on hand, competitiveness of product offerings, market conditions and product life cycles when determining excess and obsolescence and net realizable value adjustments. All of the Company’ s inventory was related to AxoBio at December 31, 2023 and is classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheets. The Company had no reserve for obsolescence as of December 31, 2023. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Maintenance and repair charges are expensed as incurred. Fixed assets are depreciated using the straight-line method using the following estimated useful lives: • Equipment – 5 - 7 years • Leasehold improvements – The lesser of 10 years or the remaining life of the lease • Furniture and fixtures – 7 years Goodwill and Intangible Assets Goodwill is not amortized but tested for impairment on an annual basis in the fourth quarter and more frequently if events or changes in circumstances indicate that the asset may be impaired. The Company’s impairment tests are based on a single reporting unit structure. The carrying value and ultimate realization of these assets is dependent upon estimates of future earnings and benefits that the Company expects to generate from their use. If the expectations of future results and cash flows are significantly diminished, intangible assets and goodwill may be impaired, and the resulting charge to operations may be material. First, the Company assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. If, after assessing qualitative factors, the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. If deemed necessary, a two-step test is used to identify the potential impairment and to measure the amount of goodwill impairment, if any. The first step is to compare the fair value of the reporting unit with its carrying amount, including goodwill. An impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. However, the impairment loss recognized should not exceed the total amount of goodwill allocated to that single reporting unit. All of the Company’s goodwill was related to the AxoBio Acquisition and totaled $ 19,188,278 as of December 31, 2023, which is classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheets. Finite-lived intangible assets are carried at cost and amortized based on an economic benefit period, which is seven to twenty years. The Company evaluates finite-lived intangible assets for impairment by assessing the recoverability of these assets whenever adverse events or changes in circumstances or business climate indicate that expected undiscounted future cash flows related to such intangible assets may not be sufficient to support the net book value of such assets. An impairment charge is recognized in the period of identification to the extent the carrying amount of an asset exceeds the fair value of such asset. Costs billed to the Company as reimbursement for third parties’ patent submissions are considered to be license fees and are expensed as incurred. Intangible assets related to AxoBio are classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheets. Finite-lived intangible assets are amortized using the straight-line method using the following useful lives: • Customer contracts – 20 years • Trade name – 7 years • Intellectual property – 7 years • Patents – 16 years Significant judgments required in assessing the impairment of goodwill and intangible assets include the assumption the Company only has a single reporting unit, identifying whether events or changes in circumstances require an impairment assessment, estimating future cash flows, determining appropriate discount and growth rates and other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value as to whether an impairment exists and, if so, the amount of that impairment. The Company has not recognized any goodwill or intangible asset impairment charges in the three months ended March 31, 2024 and 2023. Series A Voting Convertible Preferred Stock In connection with the AxoBio Acquisition, the Company issued 4,243 shares of Series A Preferred Stock to former AxoBio stockholders. Based on the limited exception under ASC 480-10-S99-3A(3)(f) for equity instruments that are subject to a deemed liquidation provision if all of the holders of equally and more subordinated equity instruments of the entity would always be entitled to also receive the same form of consideration (for example, cash or shares) upon the occurrence of the event that gives rise to the redemption (that is, all subordinate classes would also be entitled to redeem), the Company determined that the Series A Preferred Stock should be classified as permanent equity. Earnout Liability In connection with the AxoBio Acquisition, the former stockholders of AxoBio were entitled to receive the Earnout, consisting of up to $ 9,000,000 in cash and up to $ 66,000,000 in shares of Common Stock, subject to the achievement of certain revenue targets and research and development milestones. In accordance with ASC 805, Business Combinations (“ASC 805”), the Earnout was included in the purchase price for AxoBio at the Merger Closing Date and subsequently remeasured at each reporting date with changes in fair value recorded as a component of other (expense) income in the accompanying unaudited condensed consolidated statements of operations. As of December 31, 2023, the Company determined that the performance-based targets would not be met and that the Earnout would not be payable. Revenue Recognition The Company accounts for revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, revenues are recognized when control of the promised goods or services is transferred to the customer in an amount that reflects the consideration the Company expects to be entitled to in exchange for transferring those goods or services. Revenue is recognized based on the following five-step model: • Identification of the contract with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when, or as, the Company satisfies a performance obligation. Selling and Marketing Expenses Selling and marketing expenses relate to AxoBio and consist primarily of advertising expenses, commissions and freight expenses, and the distribution and marketing expenses described previously in the revenue recognition policies. Sales and marketing expenses were $ 100,000 for the three months ended March 31, 2024. These expenses are reported as a component of discontinued operations in the accompanying unaudited condensed consolidated statements of operations. Research and Development Expenses Research and development expenses are expensed as incurred and consist principally of internal and external costs, which include the cost of patent licenses, contract research services, laboratory supplies and development and manufacture of preclinical compounds and consumables for clinical trials and preclinical testing. Income Taxes Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of March 31, 2024 and December 31, 2023. The Company is currently not aware of any issues under review that could result in significant payments, accruals, or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities for all tax years subsequent to 2018 . Net Loss Per Share Under ASC 260, Earnings per Share , the Company is required to apply the two-class method to compute earnings per share (“EPS”). Under the two-class method both basic and diluted EPS are calculated for each class of common stock and participating security, considering both dividends declared (or accumulated) and participation rights in undistributed earnings. The two-class method results in an allocation of all undistributed earnings as if all those earnings were distributed. Considering that the Company has generated losses in each reporting period since its inception, the Company also considered the guidance related to the allocation of the undistributed losses under the two-class method. The contractual rights and obligations of the shares of Legacy Preferred Stock (as defined in Note 12 below) and the Company’s warrants were evaluated to determine if they have an obligation to share in the losses of the Company. As there is no obligation for the holders of Legacy Preferred Stock or the holders of the Company's warrants to fund the losses of the Company, nor is the contractual principal or redemption amount of the shares of Legacy Preferred Stock or the warrants reduced as a result of losses incurred by the Company, under the two-class method, the undistributed losses are allocated entirely to the Common Stock. Earnings per share information has been retrospectively adjusted to reflect the Business Combination ratio applied to Legacy Carmell’s historical number of shares outstanding. Shares of Alpha are considered issued for EPS purposes as of the date of the Business Combination. The Company computes basic loss per share by dividing the loss attributable to holders of Common Stock for the period by the weighted average number of shares of Common Stock outstanding during the period. The Company’s warrants, options, Legacy Preferred Stock, and convertible notes could, potentially, be exercised or converted into Common Stock and then share in the earnings of the Company. However, these convertible instruments, warrants, and options were excluded when calculating diluted loss per share because such inclusion would be anti-dilutive for the periods presented. As a result, diluted loss per share is the same as basic loss per share for the periods presented. Potentially dilutive securities, which are not included in diluted weighted average shares outstanding for the three months ended March 31, 2024 and 2023, consist of the following (in common stock equivalents): For the Three Months 2024 2023 Stock Options 1,373,511 2,299,933 Common Stock Warrants 4,617,741 94,554 Promissory Notes (if settled in shares) 184,961 — Legacy Series A Preferred Stock (if converted) — 1,228,900 Legacy Series B Preferred Stock (if converted) — 2,080,239 Legacy Series C-1 Preferred Stock (if converted) — 313,298 Legacy Series C-2 Preferred Stock (if converted) — 4,527,149 Legacy Preferred Stock Warrants — 231,291 Convertible Notes (if converted) — 1,968,320 Total 6,176,213 12,743,684 Stock-Based Compensation The Company applies the provisions of ASC 718, Compensation-Stock Compensation (“ASC 718”), which requires the measurement and recognition of compensation expense for all stock-based awards made to employees, including employee stock options, in the unaudited condensed consolidated statements of operations. For stock options issued to employees and members of the Company’s Board of Directors (the “Board”) for their services, the Company estimates each option’s grant-date fair value using the Black-Scholes option pricing model. The use of the Black-Scholes option pricing model requires management to make assumptions with respect to the expected term of the option, the expected volatility of the Common Stock consistent with the expected life of the option, risk-free interest rates, and expected dividend yields of the Common Stock. For awards subject to service-based vesting conditions, including those with a graded vesting schedule, the Company recognizes stock-based compensation expense equal to the grant date fair value of stock options on a straight-line basis over the requisite service period, generally the vesting term. Forfeitures are recorded as incurred instead of estimated at the time of grant and revised. Under Accounting Standards Update (“ASU”) 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Non-Employee Share-Based Payment Accounting , the Company accounts for stock options issued to non-employees for their services in accordance with ASC 718. The Company uses valuation methods and assumptions to value the stock options that are in line with the process for valuing employee stock options noted above. Leases The Company accounts for its leases pursuant to ASC 842, Leases , as amended. The Company’s leases consist of leaseholds on office space. The Company determines if an arrangement contains a lease at inception as defined by ASC 842. To meet the definition of a lease under ASC 842, the contractual arrangement must convey to the Company the right to control the use of an identifiable asset for a period of time in exchange for consideration. Right of Use (“ROU”) assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. Concentrations One customer accounted for 100 % of AxoBio’s revenues in 2023 and 100 % of its accounts receivable at December 31, 2023. AxoBio’s human amnion allograft product made up 100 % of revenue for the year ended December 31, 2023, which was all purchased from a single vendor, Pinnacle Transplant Technologies, LLC. Fair Value Measurements and Fair Value of Financial Instruments The Company categorizes its assets and liabilities that are valued at fair value on a recurring basis into a three-level fair value hierarchy in accordance with GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy below gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The carrying value of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, deferred consideration payable and related party loans payable approximate fair value because of the short-term maturity of such instruments. • Level 1 - Inputs are unadjusted quoted prices in active markets for identical assets or liabilities available at the measurement date. • Level 2 - Inputs are unadjusted quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data. • Level 3 - Inputs are unobservable inputs that reflect the reporting entity’s assumptions on the assumptions the market participants would use to price the asset or liability based on the best available information. Other financial assets and liabilities as of March 31, 2024 and December 31, 2023 are categorized based on a hierarchy of inputs as follows: March 31, 2024 December 31, 2023 Fair Value Carrying Estimated Carrying Estimated Input Value Fair Value Value Fair Value Hierarchy Forward purchase agreement $ 3,543,614 $ 3,543,614 $ 5,700,451 $ 5,700,451 Level 3 SBA Loan — — 1,505,070 1,498,000 Level 2 Changes in the fair value of Level 3 financial assets and liabilities for the three months ended March 31, 2024 are as follows: Forward Purchase Agreement: Balance, beginning of year $ 5,700,451 Change in fair value ( 2,156,837 ) Balance, end of period $ 3,543,614 The Forward Purchase Agreement was accounted for at fair value as a financial instrument in the scope of ASC 480, Distinguishing Liabilities from Equity , and resulted in an asset at the Closing Date. The fair value of the Company’s position under the Forward Purchase Agreement was calculated using the Call/Put Option Pricing Model. T he assumptions incorporated into the valuation model as of December 31, 2023 included the share price of $ 3.81 , the termination fee of $ 0.50 per share, the debt rate of 12.95 % and the term of 0.54 years. As of March 31, 2024, the assumptions incorporated into the valuation model included the share price of $ 2.56 , the termination fee of $ 0.50 per share, a debt rate of 13.07 % and a term of 0.29 years.

Business Combinations [Abstract]
Business Combination	NOTE 3 — BUSINESS COMBINATION AxoBio Acquisition The AxoBio Acquisition is reflected in the unaudited condensed consolidated financial statements under the acquisition method of accounting in accordance with ASC 805, with the Company treated as the accounting and legal acquirer in the AxoBio Acquisition. It was determined that AxoBio is a variable interest entity, as AxoBio’s total equity at risk is not sufficient to permit AxoBio to finance its activities without additional subordinated financial support, with the Company being the primary beneficiary. In accordance with ASC 805, the Company recorded AxoBio’s assets and liabilities at fair value. For purposes of estimating the fair value, where applicable, of the assets acquired and liabilities assumed as reflected in the unaudited condensed consolidated financial information, the Company has applied the guidance in ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), which establishes a framework for measuring fair value in acquisitions. In accordance with ASC 820, fair value is an exit price and 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.” Under ASC 805, acquisition-related transaction costs are not included as components of consideration transferred but are accounted for as expenses in the period in which the costs are incurred. The fair value of the purchase consideration transferred in the AxoBio Acquisition was as follows: Common Stock - 3,845,337 shares $ 11,270,683 Series A Convertible Voting Preferred Stock - 4,243 shares 10,382,107 Earnout 13,482,292 Deferred Consideration 8,000,000 Total estimated value of consideration transferred $ 43,135,082 The fair value of the Series A Preferred Stock was estimated at $ 2,447 per share, using the put option model, based on the market value of the Common Stock at the Merger Closing Date, conversion rate, projected conversion term, and estimated discount for lack of marketability. Deferred consideration is related to the Closing Cash Consideration of $ 8,000,000 , that was payable upon delivery of the AxoBio 2022 audited financial statements. The 2022 audited financial statements were delivered in October 2023, and as such, the cash consideration was payable at December 31, 2023. In connection with the AxoBio Acquisition, the former stockholders of AxoBio were entitled to receive payment of the Earnout consisting of up to $ 9,000,000 in cash and up to $ 66,000,000 in shares of Common Stock, subject to the achievement of certain revenue targets and research and development milestones. In accordance with ASC 815-40, as the Earnout was not indexed to the Common Stock, it was accounted for as a liability at the Merger Closing Date and is subsequently remeasured at each reporting date with changes in fair value recorded as a component of in discontinued operations in the accompanying unaudited condensed consolidated statements of operations. The fair value of the Earnout was estimated as of the Merger Closing Date using (1) the probabilities of success and estimated dates of milestone achievements in relation to the research and development milestones, and (2) probability-adjusted revenue scenarios in relation to the revenue targets. The total purchase consideration transferred in the AxoBio Acquisition has been allocated to the net assets acquired and liabilities assumed based on their fair values at the acquisition date. The transaction costs related to this acquisition of approximately $ 1,300,000 were expensed and included in the transaction-related expenses on the accompanying unaudited condensed consolidated statements of operations. The allocation of the purchase price was as follows: Total estimated value of consideration transferred $ 43,135,082 Cash and cash equivalents 662,997 Accounts receivable 18,296,000 Prepaid expenses 170,604 Inventories 10,600,000 Property and equipment 81,846 Intangible assets 23,260,000 Total assets 53,071,447 Accounts payable 12,767,909 Accrued interest 146,829 Other accrued expenses 1,390,278 Loan payable 1,498,000 Related party loans 5,610,000 Deferred tax liabilities 7,711,627 Net assets to be acquired 23,946,804 Goodwill $ 19,188,278 The Company estimated the fair value of the acquired inventories based on the selling price less costs to sell and recorded the fair value step-up of approximately $ 8,200,000 at the Merger Closing Date. The fair value step-up is amortized over the expected realization term of one year from the Merger Closing Date. The acquired loan payable of AxoBio was adjusted down to its fair value by $ 502,000 due to the more favorable than the market interest rate. This fair value step down is amortized over the term of loan payable as a credit to the interest expense. The intangible assets include trade names, customer contracts and intellectual property. The intangible assets were valued using a discounted cash flow model. The estimated fair value of the customer contracts as of the acquisition date was determined based on the projected future profits from the contracts, discounted to present value, and the likelihood of contract renewals at the end of each contract term. The estimated fair value of the intellectual property as of the acquisition date was determined based on the estimated license royalty rates, the present value of future cash flows from the intellectual property, and the expected useful life of 7 years. The estimated fair value of the trade name was determined based on the estimated royalty rates for the use of the trade name, the projected revenues attributable to the trade name discounted to present value and the expected useful life of 7 years. The goodwill and other intangible assets associated with the AxoBio Acquisition are not deductible for U.S. tax purposes. The Company determined that the AxoBio Acquisition was deemed significant to the Company in accordance with Rule 3-05 of Regulation S-X. As required by ASC 805, Business Combinations , the following unaudited pro forma statements of operations for the three months ended March 31, 2023 give effect to the AxoBio Acquisition as if it had been completed on January 1, 2022. The unaudited pro forma financial information below is presented for illustrative purposes only and is not necessarily indicative of what the operating results actually would have been during the periods presented had the AxoBio Acquisition been completed during the periods presented. In addition, the unaudited pro forma financial information does not purport to project future operating results. The pro forma statements of operations do not fully reflect: (i) any anticipated synergies (or costs to achieve synergies) or (ii) the impact of non-recurring items directly related to the AxoBio Acquisition. For the three months ended March 31, 2023 Revenue included in discontinued operations in the consolidated statements of operations $ — Add: AxoBio revenue not reflected in the consolidated statements of operations 9,398,658 Unaudited pro forma revenue $ 9,398,658 $ — Net loss from consolidated statements of operations $ ( 1,828,715 ) Add: AxoBio net income not reflected in the consolidated statements of operations, less pro forma adjustments described below (1) ( 2,636,041 ) Unaudited pro forma net loss $ ( 4,464,756 ) (1) An adjustment to reflect amortization of $ 598,459 for the three months ended March 31, 2023 that would have been charged assuming the fair value adjustments to intangible assets had been applied on January 1, 2023. The adjustment also reflects additional costs of goods sold of $ 2,037,582 for the three months ended March 31, 2023 that would have been charged assuming the fair value step up to inventories had been applied on January 1, 2023.

Substantial Doubt About Going Concern [Abstract]
Going Concern and Managements Liquidity Plans	NOTE 4 — GOING CONCERN AND MANAGEMENT’S LIQUIDITY PLANS The Company’s liquidity needs historically have been satisfied through debt and equity financing. As of March 31, 2024, the Company had cash of $ 892,161 and an accumulated deficit of $ 61,774,360 . In addition, the Company had a net loss from continuing operations of $ 3,553,162 and negative cash flows from operations of $ 1,075,778 for the three months ended March 31, 2024. Due to its current liabilities and other potential liabilities, the cash available to the Company may not be sufficient to allow the Company to operate for at least 12 months from the date these financial statements are available for issuance. The Company may need to raise additional capital through equity or debt issuances. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations and reducing payroll expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. These financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern. In April 2024, the Company sold 1,331,452 shares of its Common Stock for gross proceeds of $ 3,001,235 (see Note 15 - Subsequent Events). In addition, the Company has refocused its efforts on aesthetic products that have near-term commercial potential, reprioritized its research and development, and ceased clinical studies of product candidates that will take more than a year to commercialize. The Company is also exploring out-licensing of certain research and development programs to generate non-dilutive liquidity.

Goodwill represents the excess of the purchase price of the acquired business over the fair value of the underlying net tangible and intangible assets. The Company may record goodwill adjustments pursuant to changes in the preliminary valuations acquired during the measurement period, which is up to one year from the date of acquisition. For the year ended December 31, 2023, the Company recognized $ 19,188,278 in goodwill from the AxoBio Acquisition, which is classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheets. The Company capitalizes legal costs directly associated with the submission of Company patent applications. Gross patent costs of $ 70,746 as of March 31, 2024 are amortized on a straight-line basis over the patent term. Intangible assets acquired in connection with the AxoBio Acquisition were initially recorded at their estimated fair value as of the acquisition date (see Note 3 - Business Combination).

Debt Disclosure [Abstract]
Debt	NOTE 8 —DEBT U.S. Small Business Administration (SBA) Loan As of the Merger Closing Date, AxoBio had an outstanding loan with the SBA with total principal and accrued interest outstanding of $ 2,000,000 and $ 113,476 , respectively (the “SBA Loan”). Interest under the SBA Loan accrues at a simple interest rate of 3.75 % annually on funds outstanding as of the anniversary date of the initial borrowing. A monthly payment in the amount of $ 9,953 began in December 2023 and continues for a total of 30 years. As of December 31, 2023, there was outstanding principal and accrued interest of $ 2,000,000 and $ 134,961 , respectively. As of December 31, 2023, there was unamortized debt discount of $ 494,930 . In connection with the AxoBio Acquisition, the SBA Loan was adjusted to fair value, which, excluding accrued interest, was determined to be $ 1,498,000 . The difference in the outstanding principal and fair value of $ 502,000 was recorded as debt discount and is accreted over the remaining term of the loan using the effective interest method. For the three months ended March 31, 2024, the Company incurred interest expense and amortization of debt discount of $ 17,571 and $ 4,242 , respectively. The SBA Loan and related accrued interest are classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheets, and the related interest expense and amortization of debt discount are classified as a component of discontinued operations in the accompanying unaudited condensed consolidated statements of operations. Related Party Loans As of the Merger Closing Date, AxoBio had several promissory notes outstanding to Burns Ventures, LLC (the “Burns Notes” ) with total principal outstanding of $ 5,610,000 . The owner of Burns Ventures LLC was a former stockholder of AxoBio. Interest on the Burns Notes is payable quarterly at a fixed interest rate of 7.00 %. The Burns Notes require no monthly payments and are due in full at maturity date on December 31, 2024 . As of December 31, 2023, the Burns Notes had outstanding principal and accrued interest of $ 5,610,000 and $ 98,982 , respectively, and interest expense totaled $ 89,448 for the three months ended March 31, 2024. The Burns Notes and related accrued interest are classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheet, and the related interest expense is classified as a component of discontinued operations in the accompanying unaudited condensed consolidated statements of operations. 2023 Promissory Notes During the year ended December 31, 2023, the Company received proceeds of $ 848,500 from 26 zero coupon Promissory Notes (the “Promissory Notes”). Four of the Promissory Notes were from related parties and represented $ 100,000 of the borrowings. The Promissory Notes have a maturity date of one year from the date of issuance. The principal of the Promissory Notes is due in full at maturity. All Promissory Notes had a proportionate number of warrants issued in connection with the issuance of the Promissory Notes. There were 16,489 Common Stock warrants issued in connection with the Promissory Notes with a fair value of $ 55,062 . The warrants vested immediately and have a term of 5 years and exercise prices ranging from $ 11.50 to $ 14.30 . The fair value of the warrants was recorded as debt discount and is amortized over the term of the loans using the effective interest method. As of March 31, 2024, there was outstanding principal and unamortized debt discount of $ 473,500 and $ 6,081 , respectively. Debt discount amortization during the three months ended March 31, 2024 and 2023 was $ 13,468 and $ 703 , respectively. Pursuant to the terms of the Promissory Notes, the Board elected to repay all maturities of the Promissory Notes in shares of Common Stock. During the three months ended March 31, 2024, the Company issued 115,820 shares of Common Stock related to the maturity of Promissory Notes with a principal value of $ 375,000 . Insurance Premium Financing The Company has entered into agreements with third parties, whereby it financed a total of $ 1,043,018 of premiums on certain of its insurance policies (the “Premium Financing Programs”). The Premium Financing Programs accrue interest between 8.99 % and 9.99 % and have a total monthly payments of $ 119,833 , with the last payment due in March 2025. The remaining principal outstanding on these loans was $ 263,921 as of March 31, 2024 and interest expense totaled $ 11,566 for the three months ended March 31, 2024. January 2022 Convertible Notes On January 19, 2022, the Company issued two senior secured convertible notes (the “Convertible Notes”) of $ 1,111,111 each to two investors (the “Holders”), due on January 19, 2023. The Convertible Notes bore interest at 10 % ( 18 % upon default). The Company was required to make monthly interest payments for the interest incurred and required monthly principal payments of $ 158,730 beginning on July 19, 2022 . The Convertible Notes were collateralized by all assets (including current and future intellectual property) of Legacy Carmell. The Convertible Notes were issued with a 10 % discount and were subject to an 8 % commission due to the underwriter. These fees were recorded as debt discount. In addition, each of the Holders received warrants to subscribe for and purchase up to 155,412 shares of Common Stock (the “Convertible Note Warrants”). Each Convertible Note Warrant is exercisable at a price of $ 0.16 per warrant share, vested immediately, and has a term of five years . The fair value of the Convertible Note Warrants at the time of issuance was $ 409,483 , which was recorded as debt discount. The Convertible Notes are convertible at the option of the Holders into shares of Common Stock at a fixed conversion price equal to the lesser of $ 3.57 per share and a 25 % discount to the price of the Common Stock in a Qualified Offering (as adjusted, the “Conversion Price”). In the event units consisting of Common Stock and warrants are issued in a Qualified Offering, the Convertible Notes are convertible into Common Stock and warrants. If, at any time while the Convertible Notes are outstanding, the Company sells or grants any option to purchase or sells or grants any right to reprice, or otherwise disposes of or issues (or announces any sale, grant or any option to purchase or other disposition), any Common Stock or Common Stock equivalents entitling any person to acquire shares of Common Stock at an effective price per share that is lower than the then Conversion Price (such lower price, the “Base Conversion Price”), then the Conversion Price shall be reduced to equal the Base Conversion Price. Such adjustments are to be made whenever such Common Stock or Common Stock equivalents are issued. Multiple events have triggered the down-round feature of the base conversion price. As of December 31, 2022, the Base Conversion Price was $ 1.79 . The conversion feature within the Convertible Notes met the requirements to be treated as a derivative. Accordingly, the Company estimated the fair value of the Convertible Notes derivative using the Monte Carlo Method as of the date of issuance. The fair value of the derivative was determined to be $ 1,110,459 at the time of issuance and was recorded as a liability with an offsetting amount recorded as a debt discount. The derivative is revalued at the end of each reporting period, and any change in fair value is recorded as a gain or loss in the unaudited condensed consolidated statements of operations. Proceeds from the sales of the Convertible Notes with Convertible Note Warrants were allocated to the two elements based on the relative fair value of the Convertible Notes without the warrants and the warrants themselves at the time of issuance. The total amount allocated to the Convertible Note Warrants was $ 409,483 and accounted for as paid-in capital. The discount amount was calculated by determining the aggregate fair value of the warrants using the Black-Scholes option pricing model. On July 19, 2022, Carmell defaulted on the Convertible Notes. Under the terms of the Convertible Notes, upon an event of default, there would be a 25 % increase to the outstanding principal, in addition to the interest rate increasing from 10 % to 18 %. Upon the event of default, the unamortized debt discount of $ 958,899 was accelerated and expensed, and t he 25 % increase in outstanding principal of $ 555,556 was recorded as interest expense. An Agreement Subsequent to the Notice of Acceleration On November 2, 2022, Carmell received a letter (“Notice of Acceleration”) from one of the Holders, notifying it of an Event of Default under the Convertible Notes. Carmell and Alpha entered into an agreement with such Holder, Puritan Partners LLC (“Puritan”), in connection with the Notice of Acceleration on December 19, 2022. Pursuant to this agreement, Alpha and Carmell each represented and warranted to Puritan that (i) it intended to enter into the Business Combination, (ii) there would be no conditions to closing relating to Alpha or its affiliates delivering a certain amount of cash to the Company at closing of the Business Combination (the “Closing”), (iii) the only conditions to the closing of the Business Combination were as set forth in Sections 6.1 through Section 6.3 of the Business Combination Agreement, (iv) upon entering into such Business Combination Agreement, such parties would have a commitment letter from a third party to provide capital in an amount sufficient to the surviving company of the Business Combination to, among other things, repay all amounts due and owing at such time to Puritan at the closing, (v) the equity valuation ascribed to Carmell in the Business Combination Agreement was $ 150,000,000 , and (vi) such Business Combination Agreement shall not place any restrictions on Puritan’s ability to transfer any of its securities, including, without limitation, the shares underlying its Convertible Note Warrants. Carmell agreed it would not pay any other debtholder on account of interest or principal during the forbearance period. Based on the representations and warranties, and agreements above and in consideration of Carmell’s agreement to pay Puritan at the closing of the Business Combination (i) the outstanding principal amount, plus accrued interest, late fees and all other amounts then owed as specified in the Convertible Notes and (ii) 25,000 freely tradeable shares of Common Stock (not subject to lock-up or any other restrictions on transfer) at a price of $ 10.00 per share (i.e., the price per share of Common Stock to the equity holders of Carmell in the Business Combination), Puritan withdrew and rescinded the Notice of Acceleration, and such Notice of Acceleration was deemed null and void and had no further force or effect. Puritan further agreed that, based on the representations and warranties, and agreements contained in such agreement, it shall not issue any further notices of acceleration or default notices under the Convertible Notes, seek repayment of any amounts due under the Convertible Notes, or seek to exercise any other remedies contained in the Convertible Notes and other related agreements in regard to non-payment of the Convertible Notes from the date of the Notice of Acceleration until June 30, 2023. On the closing of the Business Combination, the Company repaid $ 2,649,874 to the Holders, which represented the original principal amount of the Convertible Notes plus accrued interest at a rate of 25 %, which the Company believes is the maximum rate permissible under New York State usury laws. In addition, the Company issued Puritan 25,000 freely tradeable shares of Common Stock. Following the closing of the Business Combination, both Holders have provided notice to the Company demanding additional payment of principal and interest on the Convertible Notes in an approximate amount of $ 600,000 per each Holder at the closing of the Business Combination with additional interest thereon. In the case of Puritan, following the Business Combination, Puritan alleged that the Business Combination constituted a “Fundamental Transaction” under the terms of the Convertible Note Warrants, resulting in a purported right for Puritan to require the Company to repurchase such Convertible Note Warrants at a purchase price equal to the Black-Scholes Value of the unexercised portion of such Convertible Note Warrants as of the closing of the Business Combination. Puritan calculated the cash amount of such repurchase to be $ 1,914,123 . The Company believes that this calculation is inaccurate. The other Holder demanded to be provided its share of the Convertible Note Warrants. Puritan has also asserted damages in connection with the timing of the issuance to it of 25,000 freely tradeable shares of Common Stock. The Company believes that it provided freely tradeable shares to Puritan at the same time as other Legacy Carmell stockholders. Puritan’s total claims, inclusive of the amounts paid at the Closing Date, exceed $ 4,050,000 in connection with a loan for which the Company received $ 1,000,000 . Management of the Company believes that its obligations under the Convertible Notes and Convertible Note Warrants have been satisfied and that no additional payments are due to the Holders, and the Company has conveyed its position to the Holders. There can be no assurance that these or similar matters will not result in expensive arbitration, litigation or other dispute resolution, which may not be resolved in our favor and may adversely impact our financial condition (see Note 10 - Commitments and Contingencies).

Commitments and Contingencies	NOTE 10 — COMMITMENTS AND CONTINGENCIES Exclusive License Agreement On January 30, 2008, the Company and Carnegie Mellon University (“CMU”) entered into a License Agreement, as amended by that certain Amendment No. 1 to License Agreement, dated as of July 19, 2011, as further amended by that certain Amendment No. 2 to License Agreement, dated as of February 8, 2016, as further amended by that certain Amendment No. 3 to License Agreement, dated as of February 27, 2020 and as further amended by that certain Amendment No. 4 to License Agreement, dated November 23, 2021 (collectively, the “Amended License Agreement”). The Amended License Agreement provides the Company an exclusive, worldwide right to use certain technology of CMU relating to biocompatible plasma-based plastics to make, have made, use, and otherwise dispose of licensed products and to create derivatives for the field of use. The Company is required to use its best efforts to effect the introduction of the licensed technology into the commercial market as soon as possible and meet certain milestones as stipulated within the Amended License Agreement. CMU retains the right to use any derivative technology developed by the Company due to its use of this technology and retains the intellectual property rights to the licensed technology, including patents, copyrights, and trademarks. The Amended License Agreement is effective until January 30, 2028, or until the expiration of the last-to-expire patent relating to this technology, whichever comes later, unless otherwise terminated under another provision within the Amended License Agreement. Failure to perform in accordance with the agreed-upon milestones is grounds for CMU to terminate the Amended License Agreement prior to the expiration date. As a partial royalty for the license rights, the Company issued 66,913 shares of Common Stock to CMU. In addition, in 2008, the Company issued a warrant which was exercised in full in 2011 for 98,938 shares of Common Stock. Prior to a qualified initial public offering or a qualified sale, CMU has the right to subscribe for additional equity securities to maintain its then percentage of ownership in the Company. The Business Combination did not qualify as a qualified initial public offering or qualified sale under the Amended License Agreement. Royalties payable by the Company to CMU are 2.07 % of net sales, as defined in the Amended License Agreement. The Company is also required to pay CMU 25 % of any sublicense fees received, due, and payable upon receipt of the sublicense fees by the Company. All payments due to CMU are due within sixty ( 60 ) days after the end of each fiscal quarter. All overdue payments bear interest at a rate equal to the Prime Rate (as defined in the Amended License Agreement) in effect at the date such amounts are due plus 4 %. No royalties were accrued or paid during the three months ended March 31, 2024 and 2023. The Company is obligated to reimburse CMU for all patent expenses and fees incurred to date by CMU for the licensed technology at the earlier of (1) three years from the effective date of the Amended License Agreement; (2) the closing date of a change in control event; and (3) for international patents, from the start of expenses for patenting outside of the United States of America. There were no reimbursed expenses and no owed related to reimbursable expenses for the three months ended March 31, 2024 and 2023. Convertible Notes As detailed in Note 8 - Debt, both Holders have provided notice to the Company demanding additional payment of principal and interest on the Convertible Notes in an approximate amount of $ 600,000 per each Holder at the closing of the Business Combination with additional interest thereon. In the case of Puritan, following the Business Combination, Puritan alleged that the Business Combination constituted a “Fundamental Transaction” under the terms of the Convertible Note Warrants, resulting in a purported right for Puritan to require the Company to repurchase such Convertible Note Warrants at a purchase price equal to the Black-Scholes Value of the unexercised portion of such Convertible Note Warrants as of the closing of the Business Combination. Puritan calculated the cash amount of such repurchase to be $ 1,914,123 . The Company believes that this calculation is inaccurate. The other Holder demanded to be provided its share of the Convertible Note Warrants. Puritan has also asserted damages in connection with the timing of the issuance to it of 25,000 freely tradeable shares of Common Stock. The Company believes that it provided freely tradeable shares to Puritan at the same time as other Legacy Carmell stockholders. Puritan’s total claims, inclusive of the amounts paid at Closing Date, exceed $ 4,050,000 in connection with a loan for which the Company received $ 1,000,000 . Management of the Company believes that its obligations under the Convertible Notes and Convertible Note Warrants have been satisfied and that no additional payments are due to the Holders, and the Company has conveyed its position to the Holders. As described in further detail below, Puritan has filed a complaint against the Company related to these allegations. There can be no assurance that these or similar matters will not result in further arbitration, litigation or other dispute resolution, which may not be resolved in our favor and may adversely impact our financial condition. Puritan Litigation On November 8, 2023 , Puritan filed a complaint captioned Puritan Partners LLC v. Carmell Regen Med Corporation et al., No. 655566/2023 (New York Supreme Court, New York County) naming the Company as a defendant. In the complaint, Puritan asserts that the Company breached its obligations under the Convertible Notes and the Convertible Note Warrants. Puritan also asserts the Company did not timely comply with its obligations to provide Puritan with 25,000 freely tradeable shares of Common Stock. Puritan asserts claims for declaratory judgment, breach of contract, conversion, foreclosure of its security interest, replevin, unjust enrichment, and indemnification, and seeks remedies, including damages totaling $ 2,725,000 through November 1, 2023, additional fees and interest thereafter, costs and attorney’s fees, an order of foreclosure on its security interest, and other declaratory relief. The Company has moved to dismiss the complaint and intends to defend itself vigorously against this litigation. There can be no assurance that this matter will be resolved in the Company’s favor, and an adverse outcome could have a material adverse effect on the Company’s financial condition.

Equity [Abstract]
Stockholders' Equity (Deficit)	NOTE 12 — STOCKHOLDERS’ EQUITY (DEFICIT) Common Stock As of March 31, 2024 and December 31, 2023, the Company’s Third Amended and Restated Certificate of Incorporation, as amended at the Closing Date, authorized the Company to issue 250,000,000 shares of Common Stock. In conjunction with the AxoBio Disposition on March 26, 2024, 3,845,337 shares of Common Stock were returned to the Company and retired. As of March 31, 2024, there were 19,361,068 shares of Common Stock outstanding. Series A Voting Convertible Preferred Stock In connection with the AxoBio Acquisition, the Company issued 4,243 shares of Series A Preferred Stock to former stockholders of AxoBio. In conjunction with the AxoBio Disposition on March 26, 2024, such shares were returned to the Company and were retired. Convertible Preferred Stock Immediately prior to the Business Combination, Legacy Carmell had outstanding Series A convertible preferred stock (“Legacy Series A Preferred Stock”), Series B convertible preferred stock (“Legacy Series B Preferred Stock”), Series C-1 convertible preferred stock (“Legacy Series C-1 Preferred Stock”) and Series C-2 convertible preferred stock (“Legacy Series C-2 Preferred Stock”), which are collectively referred to herein as “Legacy Preferred Stock.” Legacy Series A Preferred Stock, Legacy Series C-1 Preferred Stock, and Legacy Series C-2 Preferred Stock accrued cumulative dividends at a per annum rate of 7 % calculated on the original issue price (the “Original Issue Price”), respectively. Such dividends accrued on each share of Legacy Preferred Stock commencing on the date of issuance. The Company accrued dividends of $ 75,084 , $ 18,716 , and $ 217,368 for Legacy Series A Preferred Stock, Legacy Series C-1 Preferred Stock, and Legacy Series C-2 Preferred Stock, respectively, for the three months ended March 31, 2023. In connection with the Business Combination, all previously issued and outstanding shares of Legacy Preferred Stock were converted into an equivalent number of shares of Common Stock on a one-for-one basis, then multiplied by the Exchange Ratio pursuant to the Business Combination Agreement. 2023 Long-Term Incentive Plan In July 2023, the stockholders of the Company approved the 2023 Long-Term Incentive Plan (the “2023 Plan”), which replaced the Amended and Restated 2009 Stock Incentive Plan of Legacy Carmell (the “2009 Plan”). No new awards are being made under the 2009 Plan. Under the 2023 Plan, the Board may grant awards of stock options, stock appreciation rights, restricted stock, restricted stock units or other stock-based awards to employees and other recipients as determined by the Board. The exercise price per share for an option granted to employees owning stock representing more than 10 % of the Company at the time of the grant cannot be less than 110 % of the fair market value. Incentive and non-qualified stock options granted to all persons shall be granted at a price no less than 100% of the fair market value and any price determined by the Board. Options expire no more than ten years after the date of the grant. Incentive stock options to employees owning more than 10% of the Company expire no more than five years after the date of grant. The vesting of stock options is determined by the Board. Generally, the options vest over a four-year period at a rate of 25 % one year following the date of grant, with the remaining shares vesting equally on a monthly basis over the subsequent thirty-six months. The maximum number of shares that may be issued under the 2023 Plan is the sum of: (i) 1,046,408 , (ii) an annual increase on January 1, 2024 and each anniversary of such date prior to the termination of the 2023 Plan, equal to the lesser of (a) 4% of the outstanding shares of our Common Stock determined on a fully diluted basis as of the immediately preceding year-end and (b) such smaller number of shares as determined by the Board or the compensation committee of the Board, and (iii) the shares of Common Stock subject to 2009 Plan awards, to the extent those shares are added into the 2023 Plan by operation of the recycling provisions described below. The maximum number of shares of Common Stock that may be issued under the 2023 Plan through incentive stock options is 1,046,408 , provided that this limit will automatically increase on January 1 of each year, for a period of not more than ten years, commencing on January 1, 2024 and ending on (and including) January 1, 2032, by an amount equal to the lesser of 1,500,000 shares or the number of shares added to the share pool as of such January 1, as described in clause (ii) of the preceding sentence. The following shares will be added (or added back) to the shares available for issuance under the 2023 Plan: • Shares subject to 2009 Plan or 2023 Plan awards that expire, terminate or are canceled or forfeited for any reason after the effectiveness of the 2023 Plan; • Shares that after the effectiveness of the 2023 Plan are withheld to satisfy the exercise price of an option issued under the 2009 Plan or 2023 Plan; • Shares that after the effectiveness of the 2023 Plan are withheld to satisfy tax withholding obligations related to any award under the 2009 Plan or 2023 Plan; and • Shares that after the effectiveness of the 2023 Plan are subject to a stock appreciation right that are not delivered on exercise or settlement. However, the total number of shares underlying 2009 Plan awards that may be recycled into the 2023 Plan pursuant to the above-described rules will not exceed the number of shares underlying 2009 Plan awards as of the effective date of the 2023 Plan (as adjusted to reflect the Business Combination). Shares of Common Stock issued through the assumption or substitution of awards in connection with a future acquisition of another entity will not reduce the shares available for issuance under the 2023 Plan. Warrant and Option Valuation The Company computes the fair value of warrants and options granted using the Black-Scholes option pricing model. The expected term used for warrants and options issued to non-employees is the contractual life, and the expected term used for options issued to employees and directors is the estimated period that options granted are expected to be outstanding. The Company utilizes the “simplified” method to develop an estimate of the expected term of “plain vanilla” grants for stock options. The Company utilizes an expected volatility figure based on a review of the historical volatilities over a period equivalent to the expected life of the instrument valued by similarly positioned public companies within its industry. The risk-free interest rate was determined from the implied yields from U.S. Treasury zero-coupon bonds with a remaining term consistent with the expected term of the instrument being valued. The Company’s stock price was derived from a 409A valuation prior to the Business Combination and market price for all options and warrants granted thereafter. Warrants Outstanding A summary of the Common Stock warrant activity during the three months ended March 31, 2024 is as follows: Weighted Average Weighted Remaining Average Contractual Aggregate Number of Exercise Life in Intrinsic Warrants Price Years Value Outstanding and exercisable, December 31, 2023 4,638,454 $ 10.20 4.62 $ 1,382,919 Issued — — Exercised — — Expired ( 20,713 ) 6.87 Outstanding and exercisable, March 31, 2024 4,617,741 $ 10.16 4.27 $ 777,855 Option Activity and Summary A summary of the option activity during the three months ended March 31, 2024 is as follows: Number of Weighted Weighted Aggregate Outstanding, December 31, 2023 1,689,765 $ 2.72 9.00 $ 1,850,397 Granted 70,000 3.57 Expired/Cancelled ( 386,254 ) 2.90 Outstanding, March 31, 2024 1,373,511 $ 2.71 8.44 $ 193,527 Vested/Exercisable, March 31, 2024 332,737 $ 2.16 5.75 $ 149,501 The weighted average fair value of the options granted during the three months ended March 31, 2024 was based on a Black Scholes option pricing model using the following assumptions: Expected volatility 70.0 % Expected term of option 6.0 - 7.0 Range of risk-free interest rate 3.8 % - 4.3 % Dividend yield 0 % The Company recorded stock-based compensation expense for options of $ 211,469 and $ 180,509 for the three months ended March 31, 2024 and 2023, respectively.

Income Taxes	NOTE 13 – INCOME TAXES The Company did no t record any income tax provision or benefit for the three months ended March 31, 2024 and 2023. The Company provides for a valuation allowance when it is more likely than not that it will not realize a portion of its deferred tax assets. The Company has established a valuation allowance against the net deferred tax asset due to the uncertainty that enough taxable income will be generated in those taxing jurisdictions to utilize the assets. Therefore, we have not reflected any benefit of such deferred tax assets in the accompanying financial statements.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These financial statements should be read in conjunction with the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. The accompanying unaudited condensed consolidated financial statements include all adjustments that are of a normal recurring nature and necessary for the fair presentation of the results for the interim periods presented. Results for interim periods are not necessarily indicative of results to be expected for the full year.
Emerging Growth Company Status	Emerging Growth Company Status The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (the “Securities Act”), as modified by the Jumpstart our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates in these financial statements include those related to the forward purchase asset, earnout liabilities, derivative liabilities, long-term assets and goodwill impairment, the provision or benefit for income taxes and the corresponding valuation allowance on deferred tax assets, and contingent liabilities. If the underlying estimates and assumptions upon which the financial statements are based change in the future, actual amounts may differ from those included in the accompanying financial statements.
Business combinations	Business Combinations The Company allocates the fair value of the purchase consideration of its acquisitions to the tangible assets, liabilities, and intangible assets acquired based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Acquisition-related expenses are expensed as incurred and included in general and administrative expenses. The allocation of the purchase price requires management to make significant estimates in determining the fair values of assets acquired and liabilities assumed, especially with respect to intangible assets. These estimates are based on information obtained from management of the acquired companies and historical experience. These estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable, and if different estimates were used, the purchase price for the acquisition could be allocated to the acquired assets and liabilities differently from the allocation that the Company has made.
Discontinued Operations	Discontinued Operations On March 26, 2024, the Company completed the AxoBio Disposition as described in Note 1 above. In accordance with Financial Accounting Standards Board Accounting Standards Codification (“ASC”) 205, Presentation of Financial Statements, Discontinued Operations, Other Presentation Matters (“ASC 205”) , the assets and liabilities of AxoBio are classified as available for sale on the accompanying unaudited condensed consolidated balance sheets, and the results of its operations are reported as discontinued operations in the accompanying unaudited condensed consolidated statements of operations.
Segment Reporting	Segment Reporting ASC Topic No. 280, Segment Reporting (“ASC 280”), establishes standards for the way that public business enterprises report information about operating segments in their annual consolidated financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. ASC 280 also establishes standards for related disclosures about products and services, geographic areas and major customers. The Company’s business segments are based on the organizational structure used by the chief operating decision maker to make operating and investment decisions and assess performance. Our chief executive officer, who is our chief operating decision maker, views the Company’s operations and manages its business in one operating segment, which is the business of developing and commercializing aesthetic and regenerative care products.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents are held by financial institutions and are federally insured up to certain limits. At times, the Company’s cash and cash equivalents balance exceeds the federally insured limits, which potentially subject the Company to concentrations of credit risk. For the three months ended March 31, 2024 and 2023, the Company has experienced no losses related to its cash and cash equivalents that exceed federally insured deposit limits. As of March 31, 2024, the Company had cash in excess of federally insured limits of $ 392,161 . As of March 31, 2024 and December 31, 2023, the Company had cash equivalents of $ 15,107 and $ 30,000 , respectively. Cash equivalents as of December 31, 2023 are classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheets.
Accounts Receivables, net	Accounts Receivables, Net Accounts receivable are recorded at the original invoice amount. Receivables are considered past due based on the contractual payment terms. The Company reserves a percentage of its trade receivable balance based on collection history and current economic trends that it expects will impact the level of credit losses over the life of the Company’s receivables. These reserves are re-evaluated on a regular basis and adjusted as needed. Once a receivable is deemed to be uncollectible, such balance is charged against the reserve. The Company had no reserve related to the potential likelihood of not collecting its receivables as of March 31, 2024 and December 31, 2023. All of the Company’ s trade receivables were related to AxoBio at December 31, 2023 and classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheets.
Inventories	Inventories The Company’s inventory consists of finished goods and is stated at the lower of cost or net realizable value. Cost is calculated by applying the first-in-first-out method. The Company regularly reviews inventory quantities on hand and writes down to its net realizable value any inventory that it believes to be impaired. Management considers forecast demand in relation to the inventory on hand, competitiveness of product offerings, market conditions and product life cycles when determining excess and obsolescence and net realizable value adjustments. All of the Company’ s inventory was related to AxoBio at December 31, 2023 and is classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheets. The Company had no reserve for obsolescence as of December 31, 2023.
Property and Equipment	Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Maintenance and repair charges are expensed as incurred. Fixed assets are depreciated using the straight-line method using the following estimated useful lives: • Equipment – 5 - 7 years • Leasehold improvements – The lesser of 10 years or the remaining life of the lease Furniture and fixtures – 7 years
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is not amortized but tested for impairment on an annual basis in the fourth quarter and more frequently if events or changes in circumstances indicate that the asset may be impaired. The Company’s impairment tests are based on a single reporting unit structure. The carrying value and ultimate realization of these assets is dependent upon estimates of future earnings and benefits that the Company expects to generate from their use. If the expectations of future results and cash flows are significantly diminished, intangible assets and goodwill may be impaired, and the resulting charge to operations may be material. First, the Company assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. If, after assessing qualitative factors, the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. If deemed necessary, a two-step test is used to identify the potential impairment and to measure the amount of goodwill impairment, if any. The first step is to compare the fair value of the reporting unit with its carrying amount, including goodwill. An impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. However, the impairment loss recognized should not exceed the total amount of goodwill allocated to that single reporting unit. All of the Company’s goodwill was related to the AxoBio Acquisition and totaled $ 19,188,278 as of December 31, 2023, which is classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheets. Finite-lived intangible assets are carried at cost and amortized based on an economic benefit period, which is seven to twenty years. The Company evaluates finite-lived intangible assets for impairment by assessing the recoverability of these assets whenever adverse events or changes in circumstances or business climate indicate that expected undiscounted future cash flows related to such intangible assets may not be sufficient to support the net book value of such assets. An impairment charge is recognized in the period of identification to the extent the carrying amount of an asset exceeds the fair value of such asset. Costs billed to the Company as reimbursement for third parties’ patent submissions are considered to be license fees and are expensed as incurred. Intangible assets related to AxoBio are classified as a component of assets available for sale in the accompanying unaudited condensed consolidated balance sheets. Finite-lived intangible assets are amortized using the straight-line method using the following useful lives: • Customer contracts – 20 years • Trade name – 7 years • Intellectual property – 7 years • Patents – 16 years Significant judgments required in assessing the impairment of goodwill and intangible assets include the assumption the Company only has a single reporting unit, identifying whether events or changes in circumstances require an impairment assessment, estimating future cash flows, determining appropriate discount and growth rates and other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value as to whether an impairment exists and, if so, the amount of that impairment. The Company has not recognized any goodwill or intangible asset impairment charges in the three months ended March 31, 2024 and 2023.
Series A Voting Convertible Preferred Stock	Series A Voting Convertible Preferred Stock In connection with the AxoBio Acquisition, the Company issued 4,243 shares of Series A Preferred Stock to former AxoBio stockholders. Based on the limited exception under ASC 480-10-S99-3A(3)(f) for equity instruments that are subject to a deemed liquidation provision if all of the holders of equally and more subordinated equity instruments of the entity would always be entitled to also receive the same form of consideration (for example, cash or shares) upon the occurrence of the event that gives rise to the redemption (that is, all subordinate classes would also be entitled to redeem), the Company determined that the Series A Preferred Stock should be classified as permanent equity.
Earnout Liability	Earnout Liability In connection with the AxoBio Acquisition, the former stockholders of AxoBio were entitled to receive the Earnout, consisting of up to $ 9,000,000 in cash and up to $ 66,000,000 in shares of Common Stock, subject to the achievement of certain revenue targets and research and development milestones. In accordance with ASC 805, Business Combinations (“ASC 805”), the Earnout was included in the purchase price for AxoBio at the Merger Closing Date and subsequently remeasured at each reporting date with changes in fair value recorded as a component of other (expense) income in the accompanying unaudited condensed consolidated statements of operations. As of December 31, 2023, the Company determined that the performance-based targets would not be met and that the Earnout would not be payable.
Revenue Recognition	Revenue Recognition The Company accounts for revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, revenues are recognized when control of the promised goods or services is transferred to the customer in an amount that reflects the consideration the Company expects to be entitled to in exchange for transferring those goods or services. Revenue is recognized based on the following five-step model: • Identification of the contract with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when, or as, the Company satisfies a performance obligation.
Selling and Marketing Expenses	Selling and Marketing Expenses Selling and marketing expenses relate to AxoBio and consist primarily of advertising expenses, commissions and freight expenses, and the distribution and marketing expenses described previously in the revenue recognition policies. Sales and marketing expenses were $ 100,000 for the three months ended March 31, 2024. These expenses are reported as a component of discontinued operations in the accompanying unaudited condensed consolidated statements of operations.
Research and Development Expenses	Research and Development Expenses Research and development expenses are expensed as incurred and consist principally of internal and external costs, which include the cost of patent licenses, contract research services, laboratory supplies and development and manufacture of preclinical compounds and consumables for clinical trials and preclinical testing.
Income Taxes	Income Taxes Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of March 31, 2024 and December 31, 2023. The Company is currently not aware of any issues under review that could result in significant payments, accruals, or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities for all tax years subsequent to 2018 .
Net Loss Per Share	Net Loss Per Share Under ASC 260, Earnings per Share , the Company is required to apply the two-class method to compute earnings per share (“EPS”). Under the two-class method both basic and diluted EPS are calculated for each class of common stock and participating security, considering both dividends declared (or accumulated) and participation rights in undistributed earnings. The two-class method results in an allocation of all undistributed earnings as if all those earnings were distributed. Considering that the Company has generated losses in each reporting period since its inception, the Company also considered the guidance related to the allocation of the undistributed losses under the two-class method. The contractual rights and obligations of the shares of Legacy Preferred Stock (as defined in Note 12 below) and the Company’s warrants were evaluated to determine if they have an obligation to share in the losses of the Company. As there is no obligation for the holders of Legacy Preferred Stock or the holders of the Company's warrants to fund the losses of the Company, nor is the contractual principal or redemption amount of the shares of Legacy Preferred Stock or the warrants reduced as a result of losses incurred by the Company, under the two-class method, the undistributed losses are allocated entirely to the Common Stock. Earnings per share information has been retrospectively adjusted to reflect the Business Combination ratio applied to Legacy Carmell’s historical number of shares outstanding. Shares of Alpha are considered issued for EPS purposes as of the date of the Business Combination. The Company computes basic loss per share by dividing the loss attributable to holders of Common Stock for the period by the weighted average number of shares of Common Stock outstanding during the period. The Company’s warrants, options, Legacy Preferred Stock, and convertible notes could, potentially, be exercised or converted into Common Stock and then share in the earnings of the Company. However, these convertible instruments, warrants, and options were excluded when calculating diluted loss per share because such inclusion would be anti-dilutive for the periods presented. As a result, diluted loss per share is the same as basic loss per share for the periods presented. Potentially dilutive securities, which are not included in diluted weighted average shares outstanding for the three months ended March 31, 2024 and 2023, consist of the following (in common stock equivalents): For the Three Months 2024 2023 Stock Options 1,373,511 2,299,933 Common Stock Warrants 4,617,741 94,554 Promissory Notes (if settled in shares) 184,961 — Legacy Series A Preferred Stock (if converted) — 1,228,900 Legacy Series B Preferred Stock (if converted) — 2,080,239 Legacy Series C-1 Preferred Stock (if converted) — 313,298 Legacy Series C-2 Preferred Stock (if converted) — 4,527,149 Legacy Preferred Stock Warrants — 231,291 Convertible Notes (if converted) — 1,968,320 Total 6,176,213 12,743,684
Stock-Based Compensation	Stock-Based Compensation The Company applies the provisions of ASC 718, Compensation-Stock Compensation (“ASC 718”), which requires the measurement and recognition of compensation expense for all stock-based awards made to employees, including employee stock options, in the unaudited condensed consolidated statements of operations. For stock options issued to employees and members of the Company’s Board of Directors (the “Board”) for their services, the Company estimates each option’s grant-date fair value using the Black-Scholes option pricing model. The use of the Black-Scholes option pricing model requires management to make assumptions with respect to the expected term of the option, the expected volatility of the Common Stock consistent with the expected life of the option, risk-free interest rates, and expected dividend yields of the Common Stock. For awards subject to service-based vesting conditions, including those with a graded vesting schedule, the Company recognizes stock-based compensation expense equal to the grant date fair value of stock options on a straight-line basis over the requisite service period, generally the vesting term. Forfeitures are recorded as incurred instead of estimated at the time of grant and revised. Under Accounting Standards Update (“ASU”) 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Non-Employee Share-Based Payment Accounting , the Company accounts for stock options issued to non-employees for their services in accordance with ASC 718. The Company uses valuation methods and assumptions to value the stock options that are in line with the process for valuing employee stock options noted above.
Leases	Leases The Company accounts for its leases pursuant to ASC 842, Leases , as amended. The Company’s leases consist of leaseholds on office space. The Company determines if an arrangement contains a lease at inception as defined by ASC 842. To meet the definition of a lease under ASC 842, the contractual arrangement must convey to the Company the right to control the use of an identifiable asset for a period of time in exchange for consideration. Right of Use (“ROU”) assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term.
Concentrations	Concentrations One customer accounted for 100 % of AxoBio’s revenues in 2023 and 100 % of its accounts receivable at December 31, 2023. AxoBio’s human amnion allograft product made up 100 % of revenue for the year ended December 31, 2023, which was all purchased from a single vendor, Pinnacle Transplant Technologies, LLC.
Fair Value Measurements and Fair Value of Financial Instruments	Fair Value Measurements and Fair Value of Financial Instruments The Company categorizes its assets and liabilities that are valued at fair value on a recurring basis into a three-level fair value hierarchy in accordance with GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy below gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The carrying value of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, deferred consideration payable and related party loans payable approximate fair value because of the short-term maturity of such instruments. • Level 1 - Inputs are unadjusted quoted prices in active markets for identical assets or liabilities available at the measurement date. • Level 2 - Inputs are unadjusted quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data. • Level 3 - Inputs are unobservable inputs that reflect the reporting entity’s assumptions on the assumptions the market participants would use to price the asset or liability based on the best available information. Other financial assets and liabilities as of March 31, 2024 and December 31, 2023 are categorized based on a hierarchy of inputs as follows: March 31, 2024 December 31, 2023 Fair Value Carrying Estimated Carrying Estimated Input Value Fair Value Value Fair Value Hierarchy Forward purchase agreement $ 3,543,614 $ 3,543,614 $ 5,700,451 $ 5,700,451 Level 3 SBA Loan — — 1,505,070 1,498,000 Level 2 Changes in the fair value of Level 3 financial assets and liabilities for the three months ended March 31, 2024 are as follows: Forward Purchase Agreement: Balance, beginning of year $ 5,700,451 Change in fair value ( 2,156,837 ) Balance, end of period $ 3,543,614 The Forward Purchase Agreement was accounted for at fair value as a financial instrument in the scope of ASC 480, Distinguishing Liabilities from Equity , and resulted in an asset at the Closing Date. The fair value of the Company’s position under the Forward Purchase Agreement was calculated using the Call/Put Option Pricing Model. T he assumptions incorporated into the valuation model as of December 31, 2023 included the share price of $ 3.81 , the termination fee of $ 0.50 per share, the debt rate of 12.95 % and the term of 0.54 years. As of March 31, 2024, the assumptions incorporated into the valuation model included the share price of $ 2.56 , the termination fee of $ 0.50 per share, a debt rate of 13.07 % and a term of 0.29 years.
