Cabot Microelectronics to Report Higher Third Fiscal Quarter Operating Expenses Due to Litigation Costs; Revenue and Gross Margin Remain Strong

Aurora, Illinois, UNITED STATES

AURORA, Ill., July 13, 2010 (GLOBE NEWSWIRE) -- Cabot Microelectronics Corporation (Nasdaq:CCMP), the world's leading supplier of chemical mechanical planarization (CMP) polishing slurries and growing CMP pad supplier to the semiconductor industry, today announced that its operating expenses increased significantly in the third fiscal quarter, ended June 30, 2010, due to higher litigation costs. In addition, the company expects to report strong revenue and gross margin for the quarter.

The company expects to report operating expenses, which include research, development and technical, selling and marketing, and general and administrative expenses, of approximately $34.5 million in the third fiscal quarter, or $2.4 million higher than the $32.1 million reported in the previous quarter. The increase from the prior period was primarily driven by higher expenses related to the company's ongoing patent enforcement litigation with DuPont Air Products NanoMaterials, LLC during the third fiscal quarter. Following completion of the jury trial on July 8, in which the company's patents at issue were upheld, the company expects litigation costs to decrease significantly. Given the increase in operating expenses in the third fiscal quarter, the company now expects to exceed its previous guidance range for full year operating expenses of $120 million to $125 million for fiscal 2010.

The company expects to report revenue of approximately $101.7 million for the third fiscal quarter, which represents its third consecutive quarter of record revenue, approximately 3 percent higher than in the prior quarter on continued strong demand for the company's products. In addition, the company expects to report a gross profit margin of approximately 49 percent of revenue in the third fiscal quarter.

As previously announced, Cabot Microelectronics will release full financial results for its third fiscal quarter on July 22, 2010.
