Hudson Technologies, Inc. (HDSN) Closes $5.5 Million Registered Direct Offering

PEARL RIVER, N.Y.–(BUSINESS WIRE)–Hudson Technologies, Inc. (NASDAQ: HDSN) announced the closing of its previously announced registered direct offering for gross proceeds of approximately $5.5 million.

Kevin J. Zugibe, Chairman and Chief Executive Officer of Hudson Technologies, stated, “We expect to look back at 2010 as a turning point in our growth. Near-term, hot temperatures across the U.S. have increased demand for refrigerants, particularly when compared to last year’s record cool summer. Medium-term, the federally mandated phase out of R-22 refrigerants, which commenced in 2010, will create a supply gap that will need to be filled with reclaimed gas. Long-term, we anticipate continued phase outs of next generation refrigerants and ongoing growth in our refrigerants business. The augmentation of our balance sheet with the proceeds of this offering further strengthens our ability to pursue emerging opportunities in our industry.”

The company sold an aggregate of 2,737,500 shares of its common stock and warrants to purchase an aggregate of 1,368,750 shares of common stock in the offering. The warrants are exercisable at an exercise price of $2.60 per share beginning January 7, 2011 and expire January 7, 2016. Each unit, consisting of one share of common stock and a warrant to purchase 0.50 of a share of common stock, was sold for a purchase price of $2.00.

Canaccord Genuity Inc. acted as the sole placement agent for the offering.

A shelf registration statement relating to these securities (File No. 333-151973) previously was filed and declared effective by the Securities and Exchange Commission.
