Item 4.01 Changes in Registrant’s Certifying Accountant

Based on information provided by Marcum LLP (“Marcum”), the independent registered public accounting firm of CorMedix Inc. (the “Company”), CBIZ CPAs P.C. (“CBIZ CPAs”) acquired the attest business of Marcum, effective November 1, 2024. Marcum continued to serve as the Company’s independent registered public accounting firm through April 17, 2025. On April 17, 2025, Marcum resigned as the Company’s independent registered public accounting firm, and CBIZ CPAs was engaged to serve as the independent registered public accounting firm of the Company for the year ending December 31, 2025, effective immediately. The engagement of CBIZ CPAs was approved by the Audit Committee of the Company’s Board of Directors. The services previously provided by Marcum will now be provided by CBIZ CPAs.

During the years ended December 31, 2024 and 2023, and through April 17, 2025, the Company did not consult with CBIZ CPAs regarding (i) 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, or (ii) any matter that was either the subject of a disagreement (as described in Item 304(a)(1)(iv) of Regulation S-K) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).

The reports of Marcum regarding the Company’s consolidated financial statements for the fiscal years ended December 31, 2024 and 2023, did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the years ended December 31, 2024 and 2023, and through April 17, 2025, the date of Marcum’s resignation, there were (a) no disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K) between the Company and Marcum on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of Marcum, would have caused Marcum to make reference to such disagreement in its reports and (b) no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K).

The Company provided Marcum with a copy of this Current Report on Form 8-K prior to its filing with the U.S. Securities and Exchange Commission (the “SEC”) and requested that Marcum furnish the Company with a letter addressed to the SEC, pursuant to Item 304(a)(3) of Regulation S-K, 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, dated April 22, 2025, is filed as Exhibit 16.1 to this Current Report on Form 8-K and incorporated herein by reference.
