We put a new customer-focused organization in place and introduced several potentially game-changing products, including AutoClean(TM) and RegenSi(TM), which have established encouraging traction as we exit 2007." "Looking forward to 2008 and beyond, there are some industry challenges that we think create significant opportunities for ATMI. The increasing technological complexity of advanced chips is driving development costs to unprecedented levels. The strategic investments we made in 2007 in high throughput research and development capabilities are helping us to transform the development process, for both materials and the processes in which they are used. To fully capitalize on this opportunity, we are aggressively expanding our capability through investment in additional toolsets from Intermolecular, Inc. as well as the formation of a broader alliance focused on multiple key customers." Neugold continued, "Leveraging ATMI's industry-leading advanced materials portfolio, supply chain, and customer relationships with Intermolecular's highly efficient and effective technology platform should enable the leading integrated circuit producers to materially improve their return on development investments through lower direct costs and significantly reduced capital investments. The benefits for ATMI should include compressed product development cycles, significant expansion of our product portfolio and increased revenues, as well as longer term efficiency in our own research and development spending." ATMI REPORTS FOURTH QUARTER AND FULL-YEAR 2007 FINANCIAL RESULTS -- PAGE 3 OF 7 Tim Carlson, Chief Financial Officer said, "We finished 2007 with strong financial performance and believe the two recent strategic initiatives we've begun present great opportunities for further growth. The acquisition of LevTech expands our process efficiency expertise in single-use manufacturing reactors and consumables used in the bio-pharmaceutical market and should enable us to significantly accelerate our growth in this market." "Our high throughput research and development investment includes establishing development platforms close to our key customers in multiple global locations. This expanded investment will drive an additional $6 million of research and development expense in 2008, which will begin ramping in the second quarter. While the combined LevTech and high throughput research and development investments will reduce our 2008 earnings by approximately $0.15 per diluted share, we expect to see the positive financial effect from these investments beginning in 2009." Summarizing the outlook for 2008, Carlson concluded, "Given the anticipated market growth, the prospects for new product introductions, and the initial effect from our strategic investments, we expect our revenues to be in the $400 to $420 million range, and earnings per diluted share in the $1.32 to $1.48 range."
