Pursuant to Rule 416(a) under the Securities Act of 1933, as amended (the “Securities Act”), this Registration Statement shall also cover any additional shares of the registrant’s common stock, $0.0001 par value per share (“Common Stock”) which become issuable under the Registrant’s 2021 Stock Option and Incentive Plan (the “2021 Plan”) by reason of any stock dividend, stock split, recapitalization or any other similar transaction effected without the receipt of consideration which results in an increase in the number of our outstanding shares of Common Stock.

Estimated solely for the purpose of calculating the registration fee pursuant to Rules 457(c) and 457(h) of the Securities Act of 1933, as amended.

Consists of 2,044,338 additional shares issuable under the 2021 Plan, which represents an automatic annual increase to the number of shares available for issuance under the 2021 Plan effective as of January 1, 2025.
