        <footnote id="F1">Each restricted stock unit represents a contingent right to receive one share of RCAT common stock.</footnote>
        <footnote id="F2">The restricted stock units will vest in two equal annual installments: 50% on December 2, 2026, and 50% on December 2, 2027. Vesting of the restricted stock units is subject to the continuing employment by the Reporting Person with Red Cat Holdings, Inc.</footnote>

    <remarks>This Form 4 is being filed outside the required filing period due solely to an administrative delay in the reporting persons receipt of EDGAR filing credentials from the SEC which was due to a high volume of submissions at the time. The reporting person undertook the steps necessary to obtain such credentials promptly following the reportable transaction but did not receive them in time to make a timely filing. This Form 4 has been submitted promptly upon receipt of the required EDGAR filing credentials.</remarks>
