ATMI REPORTS THIRD QUARTER 2006 FINANCIAL RESULTS -- PAGE 2 of 7 Doug Neugold, ATMI Chief Executive Officer, said, "We are pleased with our performance this quarter, as we achieved strong revenues during a period when flat panel display market demand temporarily softened and global wafer starts were relatively flat. We see continued strong demand for advanced generation materials, as well as materials that address some short term opportunities for the industry. In particular, we're experiencing great interest in our RegenSi(TM) wafer reclaim/ cleaning material, and our in-situ cleans technology for the implant process. Our ViaForm Extreme(TM) copper material was named a best-known process at another of our key customers, and we are seeing escalating interest for our NOWTrak(R) Radio Frequency Identification-based materials tracking solution from several of the world's leading integrated circuit producers. These are excellent examples of the importance our customers place on working with us to improve their process efficiency." Neugold continued, "We've had a fantastic response to our Asia Technology Development Center in Taiwan, which we officially opened in September during Semicon Taiwan. With Taiwan representing nearly 20% of ATMI's sales, and with more than 55% of our revenues coming from the Asia-Pacific region, the Center puts more materials expertise and support right where our customers have asked us to put it: locally." Dan Sharkey, Chief Financial Officer said, "Revenues were up 18% year-over-year, reflecting the growth tied to our market position at the ramping 90 and 65 nanometer technology nodes. Gross margins were 51% on the strength of product mix momentum, compared with 50.4% a year ago. Operating margin has improved from 14.7% last year to 15.2% this year, even with the added effect of ATMI REPORTS THIRD QUARTER 2006 FINANCIAL RESULTS -- PAGE 3 of 7 over $2 million of equity-based compensation in 2006 pursuant to FAS 123(R). During the quarter, we recognized a non-recurring $1.7 million tax benefit, due to a provision adjustment arising from a change in certain facts and circumstances, which had a $0.04 per diluted share effect. Our balance sheet reflects continued share repurchases during the quarter, consistent with our expanded program, which added an additional $150 million authorization in August to our previous $75 million share repurchase plan. Through the end of the third quarter, we have deployed a total of $80 million on our repurchase programs." Sharkey continued, "Based on our assessment of the overall health of the industry and our market position in key sectors, despite what we believe will be a relatively flat wafer start environment, we are estimating fourth quarter revenues to range between $83 and $87 million, with diluted earnings per share in the $0.28 to $0.32 range."
