Item 4.01

Changes in Registrant’s Certifying Accountant.

On May 21, 2024, KMJ Corbin & Company LLP (“KMJ”) resigned as Mosaic ImmunoEngineering, Inc. (the “Company” or “Mosaic”) independent registered public accounting firm because KMJ’s partners and professional staff joined Crowe LLP. The Company’s Audit Committee approved the resignation on the same day.

The reports of KMJ on the Company’s consolidated financial statements for the two most recently completed fiscal years ended December 31, 2023 and 2022 did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles, except that KMJ’s audit report on the Company’s consolidated financial statements as of and for the fiscal years ended December 31, 2023 and 2022 included an explanatory paragraph indicating that there was substantial doubt about the Company’s ability to continue as a going concern.

During the Company’s two most recently completed fiscal years ended December 31, 2023 and 2022 and the subsequent interim period through the date of resignation, there were no disagreements between the Company and KMJ on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of KMJ, would have caused KMJ to make reference to the subject matter of the disagreements in connection with its audit reports on the Company’s consolidated financial statements. During the Company’s two most recently completed fiscal years ended December 31, 2023 and 2022 and the subsequent interim period through the date of resignation, there were no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K).

The Company provided KMJ with a copy of this report on Form 8-K in accordance with Item 304(a) of Regulation S-K prior to its filing with the Securities and Exchange Commission and requested that KMJ furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the above statements and, if it does not agree, the respects in which it does not agree. A copy of the letter from KMJ is filed as Exhibit 16.1 hereto.

New Certifying Accountant

The Company engaged Rose, Snyder & Jacobs LLP as its new independent registered public accounting firm on May 22, 2024. During the Company’s two most recently completed fiscal years ended December 31, 2023 and 2022 and the subsequent interim period through the date of engagement of Rose, Snyder & Jacobs LLP, neither the Company nor anyone on behalf of the Company consulted with Rose, Snyder & Jacobs LLP regarding (a) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements as to which the Company received a written report or oral advice that was an important factor in reaching a decision on any accounting, auditing or financial reporting issue; or (b) any matter that was the subject of a disagreement or a reportable event as defined in Items 304(a)(1)(iv) and (v), respectively, of Regulation S-K.
