EXPLANATORY NOTE/DEREGISTRATION OF SECURITIES

Impac Mortgage Holdings, Inc. (the “Registrant”) is filing these post-effective amendments (the “Post-Effective Amendments”) to the following Registration Statements on Form S-3 (the “Prior Registration Statements”), which have been previously filed with the Securities and Exchange Commission (the “SEC”), to deregister:

1. Any and all securities, registered but unsold or otherwise unissued as of the date hereof under Registration No. 333-46667, filed with the SEC on February 20, 1998, as amended on April 24, 1998 and June 30, 1998, respectively, registering up to 2,009,310 shares of Common Stock offered for sale, from time to time, by the selling stockholder identified thereby.

2. Any and all securities, registered but unsold or otherwise unissued as of the date hereof under Registration No. 333-63456, filed with the SEC on June 20, 2001, as amended on July 31, 2001 and August 28, 2001, respectively, registering up to 6,350,932 shares of Common Stock offered for sale, from time to time, by the selling stockholder identified thereby.

3. Any and all securities, registered but unsold or otherwise unissued as of the date hereof under Registration No. 333-52335, filed with the SEC on May 11, 1988, as amended on September 4, 1998, registering up to 1,990,147 shares of Common Stock offered for sale, from time to time, by the Registrant pursuant to the Registrant’s Dividend Reinvestment and Stock Purchase Plan.

4. Any and all securities, registered but unsold or otherwise unissued as of the date hereof under Registration No. 333-34137, filed with the SEC on August 22, 1997 and as amended on September 9, 1997, and amended by Post-Effective Amendments on each of November 14, 1997, March 16, 1998 and April 27, 1998, respectively, registering an indeterminate number of the Registrant’s Common Stock, Preferred Stock, Preferred Stock Warrants, Common Stock Warrants, Debt Securities, and Debt Securities Warrants, with an aggregate purchase price up to $200 million, offered for sale, from time to time, by the Registrant and the selling stockholder(s) identified thereby.

On April 27, 2023, the Company announced that the NYSE American, LLC (“NYSE American”) had delisted its common stock and preferred stock purchase rights as a result of the Company’s failure to comply with the NYSE American’s shareholder equity requirements. Following the delisting, on May 3, 2023 the Company’s Board of Directors determined that it was in the best interests of the Company to suspend its reporting requirements under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), with the SEC. In connection with the Company’s decision, the Company has terminated any and all offerings pursuant to the aforementioned Prior Registration Statements. Accordingly, this filing is made pursuant to an undertaking made by the Company in Part II of each the Prior Registration Statement to remove from registration by means of a post-effective amendment any securities that had been registered for issuance but remain unsold at the termination of each offering. The Company, by filing these Post-Effective Amendments, hereby terminates the effectiveness of the Prior Registration Statements and removes from registration any and all securities registered but unsold or otherwise unissued under the Prior Registration Statements as of the date hereof.
