DANBURY, Conn., July 23, 2008 (PRIME NEWSWIRE) -- ATMI, Inc. (Nasdaq:ATMI) today announced revenues of $89.5 million for the second quarter of 2008, a 3% decline compared with $92.4 million in the second quarter of 2007. Earnings per diluted share were $0.30, a 15% increase compared with $0.26 per diluted share in the second quarter of 2007.

ATMI announced on July 14th that second quarter revenue would be below expectations due to shipment delays for some SDS(r) products, reduced sales into the memory sector, and slower-than-anticipated new product adoption.

Operating income increased 15% to $13.4 million, compared with $11.6 million a year ago, while operating margin for the second quarter increased to 14.9%, compared with 12.6% for the second quarter a year earlier.

For the six months ended June 30, 2008 revenues increased 4% to $182.3 million, compared with $174.6 million in the first half of 2007. Earnings per diluted share were $0.62 in the first six months of 2008, a 41% increase compared with $0.44 per diluted share in the first half of 2007.

Operating income increased 49% to $28.5 million in the first half of 2008, compared with $19.1 million a year ago, while operating margin for the first half increased to 15.7%, compared with 11.0% in the first half of 2007. This improvement was expected given some of the operating difficulties experienced in the first half of last year.

Doug Neugold, ATMI Chief Executive Officer, said, "We understand what caused our shortfall in revenue in the second quarter, and are responding accordingly. While the broad adoption of the new AutoClean(tm) and RegenSi(tm) products is taking longer than expected, we remain confident about their ultimate prospects for success."

Tim Carlson, Chief Financial Officer, said, "Despite our disappointing revenue performance in the quarter, we improved our profitability. Gross margin improved to 51.7% in the second quarter from 48.9% a year ago, because of favorable product mix, manufacturing efficiencies, and supply chain cost-saving initiatives. Going forward, we will benefit from reduced litigation spending now that the matters with Praxair have been settled. However, given the current economic environment, we remain cautious about the outlook for the rest of the year."
