**DEREGISTRATION OF UNSOLD SECURITIES**

This Post-Effective Amendment No. 1 (this "Post-Effective Amendment") relates to the Registration Statement on Form S-1, as amended (No. 333-293451), originally filed with the U.S. Securities and Exchange Commission ("SEC") on February 13, 2026 and declared effective by the SEC on February 17, 2026 (the "Registration Statement"),which registered an aggregate of $45,000,000 of securities of Profusa, Inc. (the "Registrant").

In accordance with an undertaking made by the Registrant in the Registration Statement to remove from registration, by means of a post-effective amendment, any of the securities registered under the Registration Statement (the "Securities") that have not been sold at the termination of the offering, the Registrant hereby amends the Registration Statement by filing with the SEC this Post-Effective Amendment in order to deregister all of the Securities registered under the Registration Statement, all of which were unsold. The Securities are being removed from registration because the Securities are no longer being offered or sold pursuant to the Registration Statement. As a result of this deregistration and upon the effectiveness of this Post-Effective Amendment, no Securities will remain registered pursuant to the Registration Statement.

Pursuant to the requirements of the Securities Act of 1933, the registrant has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Berkeley, State of California, on March 2, 2026.
