Amendment to Certificate of Incorporation
On November 20, 2023, the Company filed an amendment to its Amended and Restated Certificate of Incorporation as amended, to effect a reverse stock split at a ratio of 1-for-40 (the "Reverse Stock Split"). Pursuant to the Reverse Stock Split, every 40 shares of the Company’s Class A common stock was combined into one issued and outstanding share of Class A Common Stock and every 40 shares of the Company’s Class B common stock was combined into one issued and outstanding share of Class B Common Stock. The Reverse Stock Split did not reduce the number of authorized shares of Class A and Class B common stock, which remained at 200,000,000 and 100,000,000 respectively and did not change the par value of the common stock, which remained at $0.01 per share. The Reverse Stock Split did not have any effect on the number of authorized shares of the Company’s preferred stock, par value of $0.01 per share, which would remain at 50,000,000 shares. Currently no shares of preferred stock are outstanding.
Common Stock and Pre-funded Warrants
In August 2025, the Company entered into a securities purchase agreement with certain Private Placement Investors, pursuant to which we agreed to issue and sell 5,243,732 Units to the Private Placement Investors in a private placement. Each unit is comprised of one share of Class A common stock for an aggregate of 682,018 shares, at a purchase price of $15.265 per share and Pre-Funded Warrants to purchase an aggregate of 4,561,714 shares of the Company’s Class A common stock at a price of $15.255 per Pre-Funded Warrant. Additionally, each unit has an accompanying Common Warrant to purchase an aggregate of 5,243,732 shares of the Company’s Class A common stock. We received aggregate gross proceeds from the Private Placement of approximately $80 million, before deducting offering costs payable by us. The Pre-Funded Warrants were immediately exercisable, have an exercise price of $0.01 and may be exercised at any time after the date of issuance. The Common Warrants are exercisable for (x) $22.71, if exercised for a Share, or (y) $22.70 if exercised for a Pre-Funded Warrant, after the original issuance through the termination date. The Common Warrants will expire upon the earlier to occur of (i) the fifth anniversary of the issuance of the Warrants and (ii) 90 days following the announcement of positive top-line data from the Company’s ongoing CATT1 clinical trial.
In February 2024, the Company entered into a Securities Purchase Agreement with certain Private Placement Investors, pursuant to which we agreed to issue and sell to the Private Placement Investors in a private placement (i) an aggregate of 464,377 shares of our Class A common stock, at a purchase price of $11.81 per share and (ii) issued pre-funded warrants to purchase an aggregate of 3,853,997 shares of the Company’s Class A common stock at a price of $11.80 per pre-funded warrant. The pre-funded warrants were immediately exercisable, have an exercise price of $0.01 and may be exercised at any time after the date of issuance. A holder of pre-funded warrants may not exercise the warrant if the holder, together with its affiliates, would beneficially own more than 9.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to such exercise. A holder of the pre-funded warrants may increase or decrease this percentage not in excess of 19.99% by providing at least 61 days’ prior notice to the Company.
On March 5, 2024, the Company entered into a letter agreement with the Private Placement Investors pursuant to which the Private Placement Investors agreed to exchange an aggregate of 116,493 Private Placement Shares for an aggregate of 116,590 Private Placement Pre-Funded Warrants.
Equity-Based Stock Warrants
The following table summarizes the equity-based stock warrant activity for the year ended December 31, 2025:

*Amount includes 8,470,624 Pre-Funded Warrants and 5,243,732 Common Warrants.
The Pre-Funded and Common Warrants were classified as a component of permanent equity in the Company’s Consolidated Balance Sheet as they are freestanding financial instruments that are immediately exercisable, do not embody an obligation for the Company to repurchase its own shares and permit the holders to receive a fixed number of shares of common stock upon exercise. All of the shares underlying the Pre-Funded Warrants have been included in the weighted-average number of shares of common stock used to calculate net loss per share attributable to common stockholders because the shares may be issued for little or no consideration, are fully vested and are exercisable after the original issuance date of the Pre-Funded Warrants.
G42 Investments Transaction
On May 31, 2022, the Company and G42 Investments entered in to the G42 Purchase Agreement (see Note 3), pursuant to which the Company agreed to sell to G42 Investments 259,657 shares of the Company's Class A common stock, for an aggregate purchase price of $25.0 million, consisting of (i) $12.5 million in cash at the closing of the transaction and (ii) $12.5 million in the form of a promissory note of G42 Investments to be paid at the one-year anniversary of the execution of the G42 Purchase Agreement (the "G42 Promissory Note"). On February 28, 2023, the Company and G42 Investments amended the G42 Purchase Agreement and modified the G42 Promissory Note to accelerate the payment due under the note. Pursuant to the amendment, on February 28, 2023, the Company received $12.0 million, which reflected the original amount due under the G42 Promissory Note less a 3.75% discount, in full satisfaction of the note, resulting in a loss of $0.3 million and was recognized as a component of other (expense) income net, in the Company’s Consolidated Statements of Operations.
ATM Offering
On February 28, 2024, we entered into a sales agreement (the “TD Cowen Sales Agreement”) with Cowen and Company, LLC (“TD Cowen”), pursuant to which we may offer and sell, from time to time, through or to TD Cowen, as sales agent or principal, shares of our Class A common stock, having an aggregate offering price of up to $50.0 million (the “TD Cowen ATM Offering”). Pursuant to General Instruction I.B.6 of Form S-3, at no time will we sell securities registered on the registration statement relating to the TD Cowen ATM Offering with an aggregate amount exceeding one-third of our public float during any 12-calendar month period, so long as our public float remains below $75.0 million. Under the terms of the TD Cowen Sales Agreement, we will pay TD Cowen a commission of 3.0% of the aggregate proceeds from the sale of shares and reimburse certain legal fees or other disbursements.
During the year ended December 31, 2025, the Company did not sell any shares of Class A common stock under the TD Cowen ATM Offering.
During the year ended December 31, 2024, the Company sold 179,400 shares of Class A common stock under the TD Cowen ATM Offering for net proceeds of $2.5 million.
Letter Agreement Warrants
The Company previously entered into the Letter Agreements with MacAndrews. Under the terms of the Letter Agreements, the Company had the right to sell to MacAndrews shares of its Class A common stock at a specified price per share, and MacAndrews had the right (exercisable up to three times) to require the Company to sell to it shares of Class A common stock at the same price. In addition, in connection with and as a commitment fee for the entrance into certain of these Letter Agreements, the Company also issued MacAndrews warrants (the “Letter Agreement Warrants”) to purchase additional shares of the Company’s Class A common stock. The Letter Agreement Warrants were recorded as warrant
liability, related party within the Company’s Consolidated Balance Sheets based on their fair value. The issuance of the Letter Agreement Warrants was considered to be a cost of equity recorded as a reduction to additional paid-in capital. During the years ended December 31, 2025, 2024 and 2023 the change in fair value in related party warrants was immaterial.
