PEARL RIVER, N.Y. – May 9, 2007 – Hudson Technologies, Inc. (NASDAQ: HDSN), a leading refrigerant services company specializing in proprietary on-site decontamination services for large comfort and process cooling systems, today announced results for the first quarter ended March 31, 2007.  

Revenues for the first quarter of 2007 were $8,117,000, an increase of $1,211,000 or 18% from the $6,906,000 reported during the comparable 2006 period. Net income for the first quarter was $283,000, an increase of $36,000 from the $247,000 net income reported during the first quarter 2006.  

Comments by Kevin J. Zugibe, chairman and chief executive officer, Hudson Technologies: 

“Hudson continues to improve with each passing quarter and year. We are pleased to report an 18% increase in revenues and a 15% increase in net income as compared to the first quarter of 2006. Our improved results were driven by strong refrigerant sales, which increased by more than $1.4 million over last year. Although total revenues from our RefrigerantSide® Services did decrease due to the size of the projects performed, the actual number of projects performed remained high, confirming that the demand and need for our services remains strong. Overall, our first quarter results demonstrate that we continue to grow and improve our financial standing.  

“With the milestones we have achieved and new services we continue to offer, we believe that Hudson is poised for future growth. Earlier this year we introduced Fluid Chemistry™, a simplified predictive and preventative maintenance service offering that gives an immediate look at the current condition of the refrigerant and oil in a system and can identify the existence of problems in advance of a more in-depth system analysis. With the information obtained from our Fluid Chemistry™ report, our customers can then make an informed decision as to whether or not to move forward with a more thorough examination in order to develop a detailed performance optimization plan and/or to remediate existing problems. We believe that Fluid Chemistry™ should appeal to a broader base of service contractors and system operators, and may result in greater sales of the more comprehensive analysis and remediation services offered by our ChillSmart™ service. 

“We continue to work with the U.S. Department of Energy and will perform more steam energy assessments this year. Additionally, we believe that the establishment of our second telesales office, that was announced last November, and which expanded our sales and marketing network into a several regions in the country, will provide real benefits to the Company through the coming summer months.”
