**Item 1. Description of Registrant's Securities to be Registered.** 

The class of securities to be registered hereby is the Class A common stock, par value $0.01 per share (the "Class A Common Stock"), of HMH Holding Inc., a Delaware corporation (the "Registrant"). A description of the Class A Common Stock is set forth under "Description of capital stock" in the prospectus included in the Registrant's Registration Statement on Form S-1 (Registration No. 333-281497) under the Securities Act of 1933, as amended, initially filed with the Securities and Exchange Commission on August 12, 2024, as amended (the "Registration Statement on Form S-1"). Such information will also appear in the Registrant's final prospectus that forms a part of the Registration Statement on Form S-1. Such prospectus, in the form in which it is so filed with the Securities and Exchange Commission pursuant to Rule 424(b) under the Securities Act of 1933, as amended, shall be deemed to be incorporated herein by reference.

**Item 2. Exhibits.** 

Pursuant to the Instructions as to Exhibits with respect to Form 8-A, no exhibits are required to be filed as part of this registration statement because no other securities of the Registrant are registered on The Nasdaq Stock Market LLC and the securities registered hereby are not being registered pursuant to Section 12(g) of the Securities Exchange Act of 1934, as amended.

------
