Warrants and Rights Note Disclosure [Abstract] |
Warrants | ## (10) Warrants Public Warrants Each whole Public Warrant entitles the holder to purchase one share of the Company's common stock at a price of $115.00 per share, subject to adjustment as discussed herein. Once the warrants become exercisable, the Company may call the warrants for redemption: • in whole and not in part; • at a price of $0.01 per warrant; • upon not less than 30 days’ prior written notice of redemption (the “30-day redemption period”) to each warrant holder; and if, and only if, the reported last sale price of the common stock equals or exceeds $180.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to the warrant holders. If the Company calls the warrants for redemption as described above, management will have the option to require any holder that wishes to exercise its warrant to do so on a “cashless basis.” If management takes advantage of this option, all holders of warrants would pay the exercise price by surrendering their warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the excess of the “fair market value” (defined below) over the exercise price of the warrants by (y) the fair market value. The “fair market value” shall mean the average reported last sale price of the common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. Each warrant will expire on the fifth anniversary of the Business Combination, which occurred on October 22, 2021. As a result, all outstanding warrants will expire on October 22, 2026, unless earlier exercised or redeemed in accordance with their terms. Once expired, the warrants will have no further value and will no longer be exercisable. Private Placement Warrants The Private Placement Warrants and the common stock issuable upon the exercise of the Private Placement Warrants were not transferable, assignable or saleable until after the completion of the Company's merger transaction in 2021. Additionally, the Private Placement Warrants are exercisable on a cashless basis and will be non-redeemable as long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. Each warrant will expire on the fifth anniversary of the Business Combination, which occurred on October 22, 2021. As a result, all outstanding warrants will expire on October 22, 2026, unless earlier exercised or redeemed in accordance with their terms. Once expired, the warrants will have no further value and will no longer be exercisable. PIPE Warrants and PIPE Placement Agent Warrants In December 2022, the Company entered into a securities purchase agreement with certain institutional and accredited investors for the sale by the Company of 736,337 shares of common stock and the PIPE Warrants to purchase up to 736,337 shares of common stock, in a private placement offering. The combined purchase price of each share and accompanying PIPE Warrant was $10.80 (the “December 2022 Private Placement”). Three directors of the Company participated in the December 2022 Private Placement, each paying a $1.25 premium per share and accompanying PIPE Warrant. The PIPE Warrants, including those purchased by the participating directors of the Company, are exercisable at an exercise price equal to $10.80 per share, and are exercisable for five years from the date of issuance. The Company received gross proceeds of approximately $8.0 million before deducting transaction related fees and expenses. The Company paid Brookline Capital Markets, the placement agent, a cash fee equal to seven percent of the gross proceeds received by the Company in the December 2022 Private Placement. The Company also issued Brookline Capital Markets the PIPE Placement Agent Warrants to purchase up to an aggregate of 21,091 shares of common stock, equal to 7% of the number of shares purchased by investors introduced to the Company by Brookline Capital Markets. The PIPE Placement Agent Warrants have an exercise price equal to $13.50 per share and are exercisable six months from the date of issuance and expire five years from the date of issuance. 2023 Ladenburg Agreement Warrants On March 21, 2023, the Company entered into a settlement agreement with Ladenburg Thalmann & Co. Inc. (“Ladenburg”), effective March 23, 2023 (the “2023 Ladenburg Agreement”, regarding the action brought by Ladenburg, the “Ladenburg Action”). In connection with the 2023 Ladenburg Agreement, on March 24, 2023, the Company (i) issued the Ladenburg Warrants to purchase up to 30,000 shares of common stock, exercisable for three years from the date of issuance at $5.424 per share; and (ii) furnished to Ladenburg a one-time cash payment of $500 thousand. Pursuant to the terms and subject to the conditions set forth in the 2023 Ladenburg Agreement, the Company will (i) no later than June 30, 2023, pay $1.5 million to Ladenburg in cash or shares of common stock, at the Company’s option; and (ii) no later than December 31, 2023, pay $1.1 million to Ladenburg in cash or shares of common stock, at the Company’s option. Following the completion of the Company’s obligations under the 2023 Ladenburg Agreement, Ladenburg has agreed to dismiss the Ladenburg Action with prejudice and extinguish any and all obligations of the Company in connection therewith. On June 30, 2023, in accord with the terms of the agreement, the Company issued 191,689 shares of common stock to satisfy a portion of its obligations under the 2023 Ladenburg Agreement. Following the completion of the 2023 Private Placement, the Company settled the remaining $1.1 million due to Ladenburg in cash. September 2023 Purchase Agreement Warrants As of March 31, 2026, the Company had outstanding 107,115 Preferred Tranche C Warrants to purchase shares of Series A-3 Preferred Stock having an aggregate exercise price of approximately $107.1 million. The Preferred Tranche C Warrants were classified as derivative liabilities because they are redeemable for cash upon occurrence of a Fundamental Transaction, (as defined in the Forms for such warrants), which may be outside the control of the Company. For more information see Note 8, Stockholders’ Equity. Preferred PIPE Placement Agent Warrant On November 21, 2023, the Company issued to Chardan Capital Markets LLC, the placement agent for the September 2023 Offering, a warrant to purchase 850,119 shares (as adjusted following the Reverse Stock Split) of the Company’s common stock (“the Preferred PIPE Placement Agent Warrants”). The Preferred PIPE Placement Agent Warrants have an exercise price equal to $6.30 per share (subject to adjustment for stock dividends and splits) and are exercisable in whole or in part, at any time or times on or after the issuance date and on or before October 2, 2028. The Preferred PIPE Placement Agent Warrant was classified in equity in additional paid-in capital. Preferred PIPE Series B Warrants On July 21, 2025, the Company issued the Release Date Warrants and Enrollment Date Warrants to various investors as part of the Series B Offering. The Release Date Warrants and Enrollment Date Warrants provide for the purchase of up to 500,000 and 1,000,000 shares of Series B Preferred Stock, respectively. The Release Date Warrants and Enrollment Date warrants have an exercise price of $218.75 and $175.00 per share, respectively. The Release Date Warrants have an expiration of the earlier of five years from the issuance date or the Phase II Release Date. The Enrollment Warrants have an expiration date of the earlier of five years from the issuance date or the Phase II Enrollment Date. The Release Date Warrants and Enrollment Date Warrants were initially classified as liabilities because the underlying preferred shares were redeemable, requiring the Company to settle the instruments in cash under certain conditions; however, upon receiving the requisite approval on September 26, 2025, the preferred stock was no longer redeemable, and the Release Date Warrants and Enrollment Date Warrants were reclassified from liabilities to stockholders’ equity. There were 17,000 Enrollment Warrants exercised during the three months ended March 31, 2026. Pre-Funded Warrants In March 2026, the Company issued pre‑funded warrants to purchase up to2,753,246shares of common stock at a public offering price of $3.8499per warrant, which represents the public offering price of $3.85per share of common stock less the $0.0001exercise price per share. The pre-funded warrants are indexed to the Company’s common stock and meet all other conditions for equity classification. The pre-funded warrants were classified as equity and accounted for as a component of additional-paid-in capital at the time of issuance. The following table summarizes warrant activity for the three months ended March 31, 2026 and 2025:

(1) On January 1, 2025, 42,846 Preferred Tranche B Warrants expired, unexercised. The Company recognized a gain of $3 thousand in other income in our condensed consolidated statement of operations, representing the fair value of the warrants at expiration. The valuation as of December 31, 2024, was based on a risk-free interest rate of 3.93%, an expected remaining term of 0.23 periods, implied volatility of 75%, and an underlying stock price of $309.37. Presentation and Valuation of the Warrants Liability Classified Warrants Public Warrants and Private Placement Warrants The Public Warrants and Private Placement Warrants are accounted for as liabilities in accordance with ASC 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity and were presented within warrant liabilities on the condensed consolidated balance sheets as of March 31, 2026 and December 31, 2025. The initial fair value of the warrant liabilities was measured at fair value at the Closing Date, and changes in the fair value of the warrant liabilities were presented within changes in fair value of warrant liabilities in the condensed consolidated statements of operations and comprehensive loss for three months ended March 31, 2026 and 2025. On the Closing Date, the Company established the fair value of the Private Placement Warrants utilizing both the Black-Scholes Merton formula and a Monte Carlo Simulation (the “MCS”) analysis. Specifically, the Company considered an MCS to derive the implied volatility in the publicly-listed price of the Public Warrants. The Company then considered this implied volatility in selecting the volatility for the application of a Black-Scholes Merton model for the Private Placement Warrants. The Company determined the fair value of the Public Warrants by reference to the quoted market price. The Public Warrants were classified as a Level 1 fair value measurement, due to the use of the quoted market price, and the Private Placement Warrants held privately by assignees of Big Cypress Holdings LLC, were classified as a Level 3 fair value measurement, due to the use of unobservable inputs. See Note 11, Fair Value Measurements, for changes in fair value of the Private Placement Warrants. The key inputs into the valuations as of March 31, 2026 and December 31, 2025, were as follows:
|  | March 31, 2026 |  |  | December 31, 2025 |
Risk-free interest rate |  |  | 3.75 | % |  |  | 3.83 | %
Expected term remaining (periods) |  |  | 0.56 |  |  |  | 0.81 |
Implied volatility |  |  | 231.7 | % |  |  | 200.4 | %
Closing common stock price on the measurement date |  | $ | 3.83 |  |  | $ | 3.74 |
Series A Preferred Warrants Should the Company enter into or be party to a fundamental transaction, the Company will be required to purchase all outstanding Warrants from the holders by paying cash in an amount equal to the Black Scholes Value of the unexercised portion of each Series A Preferred Warrant. As a result, the Series A Preferred Warrants are accounted for as derivative liabilities in accordance with ASC 480 and ASC 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity and were presented within warrant liabilities on the condensed consolidated balance sheets as of March 31, 2026 and December 31, 2025. The initial fair value of the warrant liabilities was measured at fair value at the Closing Date, and changes in the fair value of the warrant liabilities were presented within changes in fair value of warrant liabilities in the condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2026 and 2025. The Company established the fair value of the Preferred Warrants utilizing the Black-Scholes Merton formula. All tranches of the Preferred Warrants were classified as Level 3 fair value measurements, due to the use of unobservable inputs. See Note 11, Fair Value Measurements, for changes in fair value of the Preferred Warrants. ## The key inputs utilized in determining the fair value of each Preferred Tranche C Warrant as of March 31, 2026 and December 31, 2025, were as follows:
|  | March 31, 2026 |  |  | December 31, 2025 |
Risk-free interest rate (1) |  |  | 3.80 | % |  |  | 3.54 | %
Expected term remaining (periods) (1) |  |  | 2.66 |  |  |  | 2.91 |
Implied volatility |  |  | 102.5 | % |  |  | 105.0 | %
Underlying Stock Price (Preferred Series A) |  | $ | 312.29 |  |  | $ | 304.95 |
(1) Reflects a probability-weighted input derived from multiple Black-Scholes calculations. These calculations incorporate the Company’s estimated probability of dissolution, should SABS’ intellectual property fail to yield positive results in forthcoming clinical trials, potentially leading to dissolution before 2028. The probability was 47.5% as of March 31, 2026 and December 31, 2025.
