Exhibit 99.1

HUDSON TECHNOLOGIES ANNOUNCES OPEN MARKET SHARE

PURCHASES BY THE BOARD AND SENIOR MANAGEMENT

Woodcliff Lake, NJ – May 18, 2026–

Hudson Technologies, Inc. (NASDAQ: HDSN) (“Hudson”; or “the Company”) a leading provider of innovative 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. At the same time, we intend to expand

our services platform to reduce seasonality and diversify our earnings profile reducing the impact of short-term refrigerant price volatility.

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. The entire board has tremendous confidence in Ken Gaglione and

our management team to execute our business plan. These purchases, by every board member, reflect the Board’s commitment to align

closely with shareholders as we continue positioning Hudson for growth.”
