### PRINCIPAL SECURITYHOLDERS
The following table and accompanying footnotes set forth information known to the Company regarding the actual beneficial ownership of Common Stock, as of January 15, 2025:

• each person who is, or is expected to be, the beneficial owner of more than 5% of the outstanding shares of the Common Stock of the Company;

• each of the Company’s current directors and executive officers; and

• all directors and officers of the Company, as a group.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days.

The beneficial ownership percentages set forth in the table below are based on 27,134,033 shares of Common Stock issued and outstanding as of January 15, 2025 and does not take into account the issuance of any shares of Common Stock upon the exercise of the PIPE Warrants. In computing the number of shares of Common Stock beneficially owned by a person, we deemed to be outstanding all shares of Common Stock subject to warrants and convertible notes held by the person that are currently exercisable or convertible or may be exercised or converted within 60 days of January 1, 2024. We did not deem such shares outstanding, however, for the purpose of computing the percentage ownership
