Surmodics, Inc. (Nasdaq: SRDX) (“Surmodics” or the “Company”), a leading provider of medical device and in vitro diagnostic technologies to the health care industry, today announced that it expects to close its previously announced acquisition (the “Merger”) of the Company by an affiliate of GTCR LLC (“GTCR”) promptly. In a joint status report filed with the United States District Court for the Northern District of Illinois (the “District Court”), the Federal Trade Commission (“FTC”) and certain state regulators (“Plaintiffs”) stated that they do not intend to appeal the November 10, 2025 ruling by the District Court denying the Plaintiffs’ motion for a preliminary injunction to prevent the closing of the Merger.

“With incremental clarity from the FTC, we are pleased to be able to move forward with closing the acquisition by GTCR,” said Gary Maharaj, President and CEO of Surmodics, Inc. “Our team is now working to do so expeditiously, for the benefit of all of our stakeholders.”

Consummation of the Merger remains subject to a Temporary Restraining Order (“TRO”) under which the parties to the Merger may not consummate the Merger prior to 5:00 p.m. Central Time on Monday, November 17, 2025. The Plaintiffs, Surmodics, and GTCR have jointly moved the District Court to terminate this TRO. Consummation also remains subject to the satisfaction or waiver of closing conditions set forth in the agreement related to the Merger (the “merger agreement”), including (1) the absence of any injunction or other legal restraint or prohibition that would prevent or prohibit the consummation of the Merger, (2) the absence of a “Company Material Adverse Effect” (as defined in the merger agreement) with respect to the Company and (3) other customary closing conditions.
