Profusa, Inc. (the "Registrant") will be unable to file its Annual Report on Form 10-K (the "Form 10-K") for the fiscal year ended December 31, 2025, by March 31, 2026.

(2) Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s).

☐ Yes ☒ No

Report on Form 8-K, filed July 18, 2025, was not timely.

(3) Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?

☒ Yes ☐ No

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

The Registrant anticipates significant changes in its results of operations for the fiscal year ended December 31, 2025, as compared to the fiscal year ended December 31, 2024, primarily as a result of the Registrant's business combination that closed on July 11, 2025 (the "Business Combination"), and the related transactions. During the fiscal years ended December 31, 2025 and 2024, the Registrant recognized Net losses of $(31.9) million and $(9.2) million, respectively.

The increase in operating loss from fiscal year 2024 to fiscal year 2025 was a result of an increase in general and administrative expenses of $21.9 million primarily related to transaction costs associated with the Business Combination, an increase to R&D expenses of $1.2 million primarily related to the testing and development of the Lumee Oxygen product, and a decrease in other expenses of $0.5 million relating to an increase in gain on fair value adjustments of $1.7 million, and a reduction in interest expense of $1.9 million, offset by $2.6 million increase in financing costs, and $0.5 million increase in loss on the value of digital assets.

The change in operations resulted in a change to net loss per share, basic and diluted, from fiscal year 2024 to fiscal year 2025 of $(357.14) and $(95.37), respectively, which takes into account the 1-for-75 reverse stock split of the Registrant's common stock on February 9, 2026.

These figures reflect management's current estimates and are subject to change. Final results will be reflected in the Form 10-K to be filed.
