Item 1.01. Entry into a Material Definitive Agreement.

On August 12, 2025, CorMedix Inc. (the “Company”) completed its previously announced offering of $150,000,000 aggregate principal amount of its convertible senior notes due 2030 (the “Notes”) in a private placement, exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). Further information about the Notes (including the terms thereof) is contained in the Company’s Current Report on Form 8-K, dated August 7, 2025, which is incorporated herein by reference. In connection with the closing, the Company entered into an indenture, dated August 12, 2025, with U.S. Bank Trust Company, National Association, as trustee (the “Indenture”), governing the Notes. The initial conversion rate for the Notes was set at the time of closing and is equal to 74.2515 shares of Common Stock per $1,000 principal amount of Notes. The foregoing summary and description of the Indenture and the Notes does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Indenture and the Form of Note, which are filed as Exhibit 4.1 and Exhibit 4.2 hereto, respectively, and are incorporated by reference herein.

Item 3.02. Unregistered Sale of Securities.

The information contained above under Item 1.01, to the extent required by Item 3.02 of Form 8-K, is hereby incorporated by reference herein. The offer and sale of the Notes was made in reliance on the exemption afforded by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”) and corresponding provisions of state securities or “blue sky” laws. The Notes, and the shares of the Company’s common stock (“Common Stock”) issuable upon conversion of the Notes, have not been registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent registration with the Securities and Exchange Commission or an applicable exemption from the registration requirements. The issuance and sale of the Notes did not involve a public offering and was made without general solicitation or general advertising. Neither this Current Report on Form 8-K nor any exhibit attached hereto is an offer to sell or the solicitation of an offer to buy shares of Common Stock, the Notes or other securities of the Company.
