NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD JUNE 24, 2025

TO THE STOCKHOLDERS OF CORMEDIX INC.

The 2025 Annual Meeting of Stockholders of CorMedix Inc. (the “Annual Meeting”) will be held on June 24, 2025, at 9:00 a.m. Eastern Time. The Annual Meeting will be a virtual-only meeting conducted via live webcast, with no physical in-person meeting. You will be able to attend and participate in the Annual Meeting live via the Internet atwww.virtualshareholdermeeting.com/CRMD2025. The Annual Meeting is being held for the following purposes:

1. To elect seven directors to serve until the 2026 Annual Meeting of Stockholders and until their successor is duly elected and qualified or until their earlier resignation, removal, incapacity or death;

2. To approve on a non-binding advisory basis the compensation of our named executive officers for 2024;

3. To ratify the appointment of CBIZ CPAs P.C. as our independent registered public accounting firm for the fiscal year ending December 31, 2025; and

4. To act upon such other matters as may properly come before the meeting or any adjournment, postponement or continuation thereof.

These matters are more fully described in the proxy statement accompanying this notice.

Our Board of Directors has fixed the close of business on April 25, 2025 as the record date for the determination of stockholders entitled to notice of and to vote at the Annual Meeting or at any adjournment, postponement or continuation thereof. A list of stockholders entitled to vote at the Annual Meeting will be available for examination by any stockholder for any purpose relevant to the Annual Meeting for at least ten days prior to June 24, 2025.

This year, the meeting will take place virtually atwww.virtualshareholdermeeting.com/CRMD2025. However, to assure your representation at the meeting, you are urged to vote by proxy by following the instructions contained in the accompanying proxy statement. You may revoke your proxy in the manner described in the proxy statement at any time before it has been voted at the Annual Meeting. Any stockholder attending the Annual Meeting may vote during the meeting even if he or she has returned a proxy. Your vote is important. Whether or not you plan to attend the virtual Annual Meeting, we hope that you will vote as soon as possible.

We are pleased to take advantage of the Securities and Exchange Commission, or SEC, rules that allow us to furnish proxy materials, including this notice, and the proxy statement (including an electronic proxy card for the meeting) for the Annual Meeting via the Internet. Taking advantage of these rules allows us to lower the cost of delivering annual meeting materials to our stockholders and reduce the environmental impact of printing and mailing these materials.
