EXHIBIT 99.1 ------------ ATMI REPORTS THIRD QUARTER FINANCIAL RESULTS DANBURY, CT -- OCTOBER 24, 2007 -- ATMI, Inc. (NASDAQ: ATMI) today announced revenues increased 11% to $91.1 million in the third quarter of 2007, compared with $82.1 million in the third quarter of 2006. Net income was $11.3 million, compared with $11.4 million a year ago, while earnings per diluted share were $0.32, compared with $0.31 per diluted share in the third quarter of 2006. Earnings in the third quarter of 2006 included a $1.7 million, or $0.04 per diluted share, tax benefit. For the nine months ended September 30, 2007, revenues were $265.7 million, up 10% from $241.5 million in the comparable 2006 period. Net income decreased 7% to $26.9 million compared with $28.8 million in the first nine months of 2006, and earnings per diluted share decreased to $0.76 from $0.77, which included the $0.04 per diluted share tax benefit in 2006. Doug Neugold, ATMI Chief Executive Officer, said, "Third quarter revenues reflect strength in memory, logic, and foundry semiconductor production, as well as improving materials packaging sales for flat panel applications, which have begun to rebound after a couple quarters of relatively flat results. Beyond improved wafer starts and flat panel strength, we are very encouraged by customer interest in our new, value-based process efficiency solutions." Neugold continued, "In particular, RegenSi and AutoClean are gaining customer acceptance, and we continue to expect significant revenue contribution from these and other non-node-specific products, in 2008." -- MORE -- ATMI Reports Third Quarter 2007 Financial Results - Page 2 of 6 Tim Carlson, Chief Financial Officer said, "The third quarter results show evidence of ATMI beginning to see leverage from its growth, as operating expenses declined sequentially from last quarter. Operating margin improved to 17% in the third quarter of 2007 compared to 15% in the third quarter of last year, and 13% in the second quarter of this year." Carlson continued, "Based on current market demand, momentum in our new product ramps, and customer penetration, we estimate revenues for the fourth quarter in the range of $91 million to $96 million, with earnings per diluted share between $0.31 and $0.36." Share repurchases were $22.7 million in the third quarter and $45.6 million in the first nine months of 2007.
