Explanation of Responses:

( 1 )On July 9, 2025, the reporting person exercised options to purchase 750,000 shares of the issuer's common stock at an exercise price of $1.90 per share. The reporting person paid the exercise price on a cashless basis, resulting in the issuer withholding 241,116 of the option shares to pay the exercise price and issuing to the reporting person the remaining shares. ( 2 )Represents shares of common stock acquired upon exercise of 750,000 stock options with an exercise price of $1.90 per share. The number of shares issued was calculated by multiplying the number of options exercised by the preceding day's closing stock price of $5.91 to determine the total stock value, then subtracting the aggregate exercise price, and dividing the result by the same closing price. ( 3 )Includes shares of restricted common stock subject to forfeiture if certain vesting conditions are not met. ( 4 )The stock options vested as follows: 300,000 options vested on January 1, 2022, and the remaining options vested based upon certain performance milestones involving the issuer's stock price. ( 5 )Not applicable.
