As of June 30, 2026, all of the Service Warrants were outstanding.

Letter Agreement

In May 2025, the Company entered into a letter agreement (the “Letter Agreement”) with an existing institutional investor (the “Equity Investor”) pursuant to which the Equity Investor exercised for cash all outstanding Series B and Series C warrants, which had been previously issued in July 2024 and October 2024, respectively, at a reduced exercise price of $0.65 per share, for net proceeds of $3.9 million in consideration for the Company’s issuance of a new Series D common stock warrant (the “Series D Warrants”) to purchase an aggregate of 13,160,172 shares of Class A common stock, $0.0001 par value per share (the “Class A Common Stock”). Modification accounting was only performed on the warrants that were actually exercised pursuant to the Letter Agreement as it represented a short-term inducement. On the modification date, the Company remeasured the warrants at the reduced exercise price and recognized a $1.3 million inducement charge in the condensed consolidated statements of changes in stockholders' equity.

The Series D Warrants were exercisable immediately following stockholder approval, and will expire five years from the date of stockholder approval and have an exercise price of $0.65 per share. The Series D Warrants include certain rights upon “fundamental transactions,” as described in the Series D Warrant agreement, including the right of the holders thereof to receive from the Company or a successor entity the same type or form of consideration (and in the same proportion) that is being offered and paid to the holders of Class A common stock in such fundamental transaction in the amount of the Black Scholes value of the unexercised portion of the applicable Series D Warrants on the date of the consummation of the fundamental transactions. The Series D Warrant is classified as equity on the Company's condensed consolidated balance sheet. In October 2025, pursuant to the Letter Agreement, the equity investor exercised the Series D Warrants to purchase 6,967,150 shares of Class A Common Stock for cash proceeds of $4.5 million. As of June 30, 2026, there were 6,193,022 Series D Warrants outstanding.

Pursuant to the terms of the Letter Agreement, in the event that the exercise of the Series B and Series C warrants would have otherwise caused a holder to exceed the beneficial ownership limitations set forth in the existing warrant, the Company issued the number of shares that would not cause a holder to exceed such beneficial ownership limitation and agreed to hold such balance of shares of Class A Common Stock in abeyance. Accordingly, an aggregate of 1,161,000 shares of Class A Common Stock from the exercise of the Series B and Series C warrants were held in abeyance (the “Abeyance Shares”) with such Abeyance Shares evidenced through the holder’s existing warrants and which are deemed to be prepaid. The Abeyance Shares were to be held until notice is received by the holder that the balance of the shares of Class A Common Stock may be issued in compliance with such beneficial ownership limitations and may be exercised pursuant to a notice of exercise from the holder. The Abeyance Shares were subsequently released and considered shares of Class A Common Stock in July 2025.

Loan and Security Agreement Warrants

In August 2022, in conjunction with a loan and security agreement, the Company issued warrants to purchase 76,336 shares of the Company's Class A common stock. The warrants are exercisable for a period of five years from the grant date, as may be adjusted for certain anti-dilution adjustments, dividends, stock splits, and reverse stock splits, at an exercise price per share equal to $11.79, which may be net share settled at the option of the holder. The warrants are classified as equity on the Company’s condensed consolidated balance sheet. In September 2025, the Company modified the exercise price of the warrants to $0.50 in consideration for a deferral of a principal repayment due in October 2025. There were no other changes to the terms of the warrant agreement. On the modification date, the Company remeasured the warrants at the reduced exercise price and recognized an additional $15 thousand as interest expense in the condensed consolidated statements of operations. As of June 30, 2026, there were 76,336 warrants outstanding.
