HUDSON TECHNOLOGIES, INC. REPORTS
FIRST QUARTER 2000 RESULTS

PEARL RIVER, New York – Hudson Technologies, Inc. (NASDAQ:HDSN), a leading refrigerant services company specializing in emergency recovery and decontamination services for large comfort and process cooling systems, today announced results for the three month period ended March 31, 2000. 

Revenues for the three months ended March 31, 2000, were $3.1 million compared to $5.0 million for the comparable 1999 period. The reduction in revenues in the first quarter of 2000 was primarily due to an anticipated reduction in refrigerant sales to the automotive aftermarket industry and, to a lesser extent, the loss of revenues from the Company’s former subsidiary Environmental Support Solutions (“ESS”). The Company reported a net loss of $(852,000) for the first quarter of 2000 and, including dividends of $122,000 on preferred stock, the loss per share is $(0.19). This compares to a net loss of $(856,000) or $(0.17) per share for the comparable 1999 period. 

“A key element of our business plan is the development of a more stable and higher margin revenue mix through the replacement of low margin refrigerant sales with our on-site services. Pursuant to that plan, during 1999 we began to invest in a sales and service infrastructure to support our on-site services which now includes facilities servicing eleven markets throughout the United States. We are beginning to see results from the investment in our on-site service capabilities as on-site revenues increased by 64% in the first quarter of 2000 as compared to the first quarter of 1999. We are particularly pleased that our enhanced revenue mix over this period enabled us to increase our gross profit margin to 32% from 24%, despite a 39% decrease in our overall revenues. We believe that the trend toward increased on-site service revenues, reduced low margin refrigerant sales revenues and higher gross profit margins will continue,” said Kevin Zugibe, the Company’s Chairman and Chief Executive Officer.
