Kevin J. Zugibe, Chairman and Chief Executive Officer of Hudson Technologies commented, "Our third quarter results demonstrate that we continue to grow our business and expand our customer base. We achieved record revenues in the third quarter, significantly surpassing our revenues for the third quarter in 2010. Furthermore, our nine months revenues surpass our record 2010 full year revenues. Despite an industry-wide decline in the price of R-22 refrigerant ("R-22") which impacted our margins, we achieved strong revenue growth due to increases in the total volumes of product sold and in services performed in the third quarter. While our pricing expectations for R-22 did not materialize, the expansion of our business and customer base should serve us well when market conditions stabilize.

"Our revenue growth during the quarter was also achieved without a material increase in reclamation. Despite the EPA's efforts, through the phase down and ultimate phase out of R-22, to reduce the supply of virgin R-22, there is clearly an oversupply, which we believe is a primary cause for the reduced pricing in the industry. Consequently, we have yet to see the price increases in R-22 that were anticipated during the phase down period, and as a result, the industry has experienced an approximate 20% decline in the volumes of R-22 reclaimed when compared to 2008 levels. The EPA is currently evaluating the existing phase down schedule for the production and import of R-22 and has solicited stakeholder comments on whether it should revise the phase down levels for the 2012, 2013 and 2014 years. Without exception, every stakeholder that has publicly commented on the current R-22 phase down levels has indicated that it is their belief that the levels for R-22 production and importation are too high and should be reduced. It is our expectation that the EPA will issue new regulations to establish R-22 production and import levels for the 2012 year in the near future. While we cannot control the market dynamics around refrigerant pricing, we remain focused on expanding our customer base and enhancing our relationships with the goal of continuing to deliver sustainable revenue growth despite pricing volatility.

"The establishment of our joint venture, Hudson Technologies Europe S.r.l., for the development of reclamation, remediation and energy optimization services throughout most of Europe, the Middle East and North Africa continues to progress. We believe that this joint venture positions us well to capitalize on servicing and efficiency opportunities created by the regulatory environment and high energy prices in Europe and in emerging markets where the use of refrigeration and cooling systems is increasing.

"As the market landscape for our industry continues to evolve, we recognize the importance of ensuring that our broad product and service offerings provide the right solution in the right place at the right time. As we focus our efforts to execute on this strategy, we believe we can drive sustainable revenue and earnings growth."
