 offering is based on 14,525,960 shares outstanding as of June 28, 2025, which excludes:

| • | 5,500 shares of common stock issued upon the exercise of an outstanding stock option on August 26, 2025, of which 2,183 shares were acquired by the Company in this cashless exercise transaction; |

| • | 1,083,300 shares of common stock issuable upon the exercise of outstanding stock options as of June 28, 2025, with a weighted-average exercise price of $2.45 per share; |

| • | 421,400 shares of common stock reserved for future issuance under our 2020 Plan; |

To the extent any options are exercised or restricted stock units vest, new options, restricted stock awards or restricted stock units are issued under our equity incentive plans, or we otherwise issue additional shares of common stock in the future, there will be further dilution to new investors.

In addition, we may choose to raise additional capital due to market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or debt securities, the issuance of these securities could result in further dilution to our stockholders.
