<div id="readability-page-1">WOODCLIFF LAKE, N.J., March 27, 2026 (GLOBE NEWSWIRE) -- Hudson Technologies, Inc. ( HDSN ) (“Hudson”; “the Company”) 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 – announces that it has signed a licensing agreement with Solstice Advanced Materials ( SOLS ) for the reclamation and resale of R-448A and R-449A refrigerants. These patented HFO refrigerant blends are two of the leading alternative refrigerants used in accordance with the AIM Act when replacing higher GWP HFC refrigerants with lower GWP HFO refrigerants in the supermarket segment. The terms of the licensing agreement allow Hudson Technologies ( HDSN ) to reclaim and resell R-448A and R-449A in the United States and Canada. Ken Gaglione, President and Chief Executive Officer of Hudson Technologies ( HDSN ) commented, “This agreement provides Hudson a meaningful opportunity to grow our presence in the commercial refrigeration space by enabling our reclamation and resale of patented next generation lower GWP refrigerants. Legacy refrigerants such as R-404A and R-507 are becoming progressively constrained under the ongoing national phase-down of HFCs and by state and local regulations mandating the use of reclaimed or lower GWP materials. Two of the most popular lower-GWP choices have been R-448A and R-449A, creating a large new opportunity for aftermarket service gas demand. Our agreement with Solstice builds upon our long-term relationship with Solstice and aligns with our strategic focus to expand our sales and service capabilities with next generation refrigerants.” About Hudson Technologies ( HDSN ) Hudson Technologies, Inc.
