(NASDAQ: HDSN) (“Hudson”; or “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 – today announced all members of its board and certain members of senior management have increased their positions in Hudson Technologies common stock with open market stock purchase transactions.  “Hudson’s long-term potential is being realized through disciplined investment in our core business, allowing us to capitalize on the regulatory-driven scarcity of HFCs expected under the AIM act, and strengthen our leadership position in the refrigerants market.

We are committed to increased transparency and disciplined execution, and these share purchases reflect the Board’s and management’s confidence in the strength of our business, the opportunities ahead of us, and our strategy to drive sustainable growth and shareholder value,” commented Ken Gaglione, President and Chief Executive Officer of Hudson Technologies. Lead Independent Director Rich Parrillo, commenting on Hudson’s renewed direction, stated, “Hudson is entering an exciting period of growth with strong leadership, a clear strategy, and a renewed focus on driving shareholder value.
