Explanation of Responses:

1. On October 23, 2025, the Reporting Person was granted a Strategic Advisory Warrant to purchase 520,833 shares of Class A common stock at $0.01 per share. Following the Issuer's 1-for-8 reverse stock split effective April 6, 2026, the Warrant was adjusted to cover 65,104 shares at $0.08 per share.

2. On June 1, 2026, the Reporting Person exercised 30,000 Warrant Shares on a cashless basis under Section 2(c) of the Warrant. Using the May 29, 2026 VWAP of $3.3854, the formula yielded 29,291.0734 net shares. The Issuer elected to round up to the next whole share, resulting in the issuance of 29,292 net shares.

3. Due to an administrative error, the Issuer initially delivered all 30,000 shares without deducting shares for the $0.08 exercise price. Before this Form 4 was filed, the Reporting Person returned 708 excess shares to the Issuer, and the Issuer cancelled them. Table I reports the gross acquisition of 30,000 shares and the disposition of 708 shares to reflect the corrected cashless exercise. No open-market sale occurred and the Reporting Person received no cash proceeds.

4. No consideration was paid or received for the derivative security. Because the reported transaction was an exercise of the Warrant, the exercise price of $0.08 per share is reported in Column 2, and Column 8 is left blank pursuant to Form 4 Instruction 4(c)(iii).
