EXHIBIT 99.1 PRESS RELEASE FOR IMMEDIATE RELEASE CONTACT: William S. Johnson Vice President and Chief Financial Officer Cabot Microelectronics Corporation (630) 375-5591 CABOT MICROELECTRONICS REPORTS RESULTS FOR THIRD FISCAL QUARTER 2004 AND ANNOUNCES SHARE REPURCHASE PROGRAM AURORA, IL, July 22, 2004 - Cabot Microelectronics Corporation (Nasdaq: CCMP), the leading supplier of chemical mechanical planarization (CMP) polishing slurries to the semiconductor industry, today reported financial results for its third fiscal quarter, which ended June 30, 2004. The company also announced that its Board of Directors has authorized a share repurchase program for up to $25 million of the company's outstanding common stock. Total revenue for the third fiscal quarter of 2004 was $76.9 million, up 4.6% from $73.5 million in the prior quarter and up 19.7% from $64.3 million in the third quarter a year ago. Slurries used for copper, tungsten, and oxide polishing applications all experienced sequential revenue increases this quarter. Average selling price also rose sequentially by 2.0%, due to a higher valued product mix than in the prior quarter, partially offset by selected price reductions. Gross profit for the quarter was $39.0 million, up by 7.9% from the prior quarter's $36.1 million, and up 18.5% from $32.9 million in the year ago quarter. As a percentage of revenue, gross profit increased to 50.7% this quarter from 49.2% last quarter, primarily due to the benefits of higher manufacturing capacity utilization and a more favorable product mix versus the previous quarter, partially offset by selected price reductions. Gross profit in the same quarter of last year represented 51.2% of revenue. Operating expenses of $21.1 million, consisting of research and development, selling and marketing, and general and administrative expenses, decreased by $0.2 million sequentially, and were $2.8 million higher than the same quarter last year. Net income for the quarter was $12.2 million, up by 26.0% from $9.7 million last quarter, and up 25.4% from $9.8 million in the same quarter last year. Diluted earnings per share were $0.49 this quarter, compared to $0.39 in the previous quarter and $0.40 in the year ago quarter. In addition, with respect to the $25 million share repurchase program, share repurchases will be funded from the company's cash balance, which as of June 30, 2004 was $155.9 million, and are primarily intended to diminish dilution -MORE- CABOT MICROELECTRONICS REPORTS RESULTS FOR THIRD FISCAL QUARTER 2004............................................PAGE 2 of 5 from stock option and employee stock purchase plans. Share repurchases under the program may be made at management's discretion from time to time, depending on market conditions, in open market transactions. The program, which is effective immediately, may be suspended or terminated at the company's discretion. At present, the company has approximately 24.8 million shares of common stock outstanding and an aggregate market capitalization of approximately $680 million. "We are proud of our strong financial performance this quarter, including our achievement of a record level of quarterly revenue," stated William P. Noglows, Chairman and CEO. "Our company has recently realized progress on a number of important initiatives that we believe will contribute toward our long term success. First, in support of our strategy to enlarge and strengthen our already substantial presence in the Asia Pacific region, we purchased additional land adjoining our existing facilities in Japan to expand our current infrastructure there. Second, as part of our strategy of continued technology leadership, we entered into a strategic alliance with NanoProducts Corporation, a technology leader in the field of nanoscale particles, and also obtained a minority equity position in the company, which we believe will allow us to leverage innovative next generation abrasives for our CMP slurries and other fine finish polishing applications. Finally, we believe the implementation of our share repurchase program represents a prudent use of a portion of our growing cash balance. We are excited about the progress we have made, as demonstrated by these important initiatives, and we believe we are well positioned for continued leadership in this competitive arena."
