Exhibit 99.1

U.S. COURT OF APPEALS FOR THE FEDERAL CIRCUIT AFFIRMS VICTORY FOR CORMEDIX THERAPEUTICS IN MINOCIN^® PATENT LITIGATION

Parsippany, NJ – June 8, 2026 – CorMedix Therapeutics (Nasdaq: CRMD) today announced that the United States Court of Appeals for the Federal Circuit has affirmed the judgment of the U.S. District Court for the Northern District of Illinois that the patents covering its product MINOCIN^® for Injection are valid and infringed by the product developed by Nexus Pharmaceuticals, Inc.

Following a four-day bench trial in 2023, the district court found in favor of CorMedix’s wholly owned subsidiary Melinta Therapeutics on all patent infringement and validity issues. The Federal Circuit’s decision on Friday upheld the district court’s findings that Nexus’ proposed generic minocycline product infringes the MINOCIN^® patents and rejected Nexus’ invalidity challenge. The Federal Circuit also affirmed the district court’s permanent injunction barring Nexus from marketing its generic product prior to patent expiration. The patents-at-issue are FDA Orange Book listed and protect the company’s innovative reformulation of intravenous minocycline, marketed as MINOCIN^® for Injection. MINOCIN^® is a tetracycline derived antibiotic used primarily in hospital and acute care settings for patients with a variety of serious and drug-resistant infections.

“We are pleased that the Federal Circuit has affirmed the district court’s thorough and well-reasoned decision,” said Joseph Todisco, CorMedix Chairman and CEO. “This ruling validates the strength of the MINOCIN^® intellectual property portfolio and recognizes the innovative work that led to important improvements in intravenous minocycline therapy for patients. The decision reinforces the importance of protecting pharmaceutical innovation and the substantial investments required to develop improved therapies. We will continue to protect and defend CorMedix’s intellectual property.”
