Subsequent Events	Note 17. Subsequent Events January 2026 Securities Purchase Agreement On January 5, 2026, the Company entered into a Securities Purchase Agreement for a private placement of securities. The private placement closed on January 6, 2026, resulting in aggregate gross proceeds of approximately $5.0 million, before deducting placement agent commissions and offering expenses. Pursuant to the agreement, the Company issued (i) pre-funded warrants to purchase an aggregate of 925,926 shares of Class A common stock at an exercise price of $0.00001 per share (exercisable immediately and with no expiration date until fully exercised), and (ii) Class A common warrants to purchase an aggregate of 925,926 shares of Class A common stock at an exercise price of $5.40 per share (exercisable following stockholder approval and expiring five years from the stockholder approval date). The securities were sold without registration under the Securities Act of 1933, as amended, in reliance on Section 4(a)(2) and Rule 506(b) thereunder. The Company also issued placement agent warrants to AGP to purchase 46,296 shares of Class A common stock at an exercise price of $5.94 per share, exercisable beginning 180 days after the commencement of sales in the offering. The warrants include beneficial ownership limitations (4.99% of outstanding Class A common stock or voting power) and are subject to standard adjustments for stock splits, dividends, and similar events.
