HUDSON TECHNOLOGIES PROVIDES UPDATE ON STATUS OF DEFENSE LOGISTICS AGENCY CONTRACT

WOODCLIFF LAKE, NJ – JANUARY 30, 2026 –Hudson Technologies, Inc. (NASDAQ: HDSN) a leading provider of innovative and sustainable refrigerant products and services to the Heating, Ventilation, Air Conditioning, and Refrigeration industry – and one of the nation’s largest refrigerant reclaimers – today provided an update on the status of its previously announced contract with the United States Defense Logistics Agency (“DLA”) awarded in October 2025 and set to commence in July 2026 (the “2025 DLA Contract”). Hudson has served as prime contractor since 2016 and was awarded this new contract following a standard periodic competitive review and rebidding process.

Hudson Technologies was recently notified that a competitor has filed a bid protest at the U.S. Court of Federal Claims, challenging the DLA’s evaluation of proposals and the contract award to Hudson Technologies. In response, the DLA is reviewing its evaluation to determine whether corrective action is necessary and has rescinded the 2025 DLA Contract award during this process. While the bid protest and corrective action is pending, Hudson will continue providing logistics support under its existing contract which runs through July 2026.

Kenneth Gaglione, President and Chief Executive Officer of Hudson Technologies commented, “Hudson has a proven and successful 10-year working relationship with the DLA. While this development is disappointing, bid protests are a common occurrence in government contracting matters, and we are confident that Hudson is in the best position to ultimately receive this contract. We are intent upon preserving our position as a valued partner to the DLA while this protest is being resolved and look forward to continuing our support of the DLA during this interim period.”
