EXPLANATORY NOTE

REGISTRATION OF ADDITIONAL SECURITIES

This Registration Statement on Form S-8 (the "Registration Statement") registers 1,208,882 additional shares of common stock of Tenon Medical, Inc., Delaware corporation, (the "Registrant") to be issued pursuant to the Registrant's Tenon Medical, Inc. 2022 Equity Incentive Plan, as amended (the "2022 Plan").

Pursuant to General Instruction E of Form S-8 under the Securities Act of 1933, as amended ("Securities Act"), this Registration Statement consists only of those items required by General Instruction E to Form S-8. Accordingly the Registrant incorporates by reference into this Registration Statement the contents of (1) the registration statement on Form S-8 (File No. 333-268360), filed with the Securities and Exchange Commission (the "SEC") on November 15, 2022, relating to the registration of 29,092 shares of Registrant's common stock, par value $0.001 per share ("Common Stock") authorized for issuance under the 2022 Plan , and (2) the registration statement on Form S-8 (File No. 333-271778), filed with the SEC on May 9, 2023, relating to the registration of additional 5,618 shares of Common Stock authorized for issuance under the 2022 Plan, in each case, except for Items 3 and 8, which are being updated by this Registration Statement.

Since May 9, 2023, the number of shares of Common Stock reserved and available for issuance under the 2022 Plan has been increased as follows: (i) by 13,002 shares pursuant to an automatic increase under the 2022 Plan as of January 1, 2024; (ii) by 137,500 shares as approved by the stockholders holding a majority of the voting power of the Registrant as of July 23, 2024, (iii) by 13,750 shares pursuant to an automatic increase under the 2022 Plan as of January 1, 2025, and (iv) by 1,138,495 shares as approved by the stockholders holding a majority of the voting power of the Registrant as of September 18, 2025 ("September 2025 Amendment").

This Registration Statement provides for the registration of an additional 1,208,882 shares of Common Stock issuable under the 2022 Plan. These 1,208,882 shares represent: (i) 70,387 shares of Common Stock, that are reserved and available for issuance under the 2022 Plan and have not been registered by the Registrant pursuant to previously filed registration statements on Form S-8, and (ii) 1,138,495 shares, reserved and available for issuance under the 2022 Plan pursuant to the September 2025 Amendment.

The Common Stock share amounts stated above are presented on a post-split basis and reflect the 1-for-10 reverse stock split effected by the Registrant on November 2, 2023 and the 1-for-8 reverse stock split effected by the Registrant on September 6, 2024.
