CABOT MICROELECTRONICS CORPORATION REPORTS

STRONG RESULTS FOR THIRD QUARTER OF FISCAL 2013

Revenue of $110.0 Million, Up Approximately 10 Percent Sequentially

Gross Profit Margin of 49.7 Percent of Revenue, Up 150 Basis Points Sequentially

Earnings Per Share of 65 Cents, Up From 40 Cents in Prior Period

AURORA, IL, July 30, 2013 – Cabot Microelectronics Corporation (Nasdaq:  CCMP), the world's leading supplier of chemical mechanical planarization (CMP) polishing slurries and a growing CMP pad supplier to the semiconductor industry, today reported financial results for its third quarter of fiscal 2013, which ended June 30, 2013.

Total revenue during the third fiscal quarter was $110.0 million.  This reflects an increase of 9.6 percent from the prior quarter, on solid demand for the company's products, as semiconductor industry demand strengthened following relatively soft conditions during the first half of the fiscal year, as well as growth in demand for the company's QED products.  The company achieved gross profit margin of 49.7 percent of revenue, which represents increases of 200 and 150 basis points year-over-year and sequentially, respectively.  Diluted earnings per share were $0.65, compared to $0.40 in the prior quarter.  The company's balance sheet reflects a cash balance of $201.6 million, $13.3 million higher than in the prior quarter, and $166.3 million of debt outstanding as of June 30, 2013.

"We are pleased with our strong financial performance this quarter, which we believe reflects the continued successful execution of our strategic business initiatives, coupled with strengthening of overall semiconductor industry demand that we had anticipated to occur during the quarter", said William Noglows, Chairman and CEO of Cabot Microelectronics.  "Our revenue grew by almost 10 percent sequentially, and notably, revenue from our Pads business grew by 14 percent compared to the prior period.  Additionally, we achieved strong profitability as our gross margin of 49.7 percent of revenue and diluted earnings per share of 65 cents were each at the highest quarterly levels since the December quarter of 2010.  Heading into what is typically a seasonally strong fourth fiscal quarter, I am confident that we are well-positioned to continue to develop and deliver innovative, high-quality solutions to our customers and continue to provide value for our shareholders."

Total third fiscal quarter revenue of $110.0 million represents a 4.9 percent decrease from the record revenue of $115.7 million achieved in the same quarter last year, and a 9.6 percent increase from $100.4 million reported last quarter.  Compared to the same quarter last year, revenue from the company's aluminum CMP slurry products increased, while revenue from all other major business areas decreased.  Compared to the prior quarter, revenue from all of the company's business areas increased except for revenue from slurries for data storage applications.  Year to date revenue of $316.9 million is essentially even with the prior year's.

Gross profit, expressed as a percentage of revenue, was 49.7 percent this quarter.  This is higher than both the 47.7 percent of revenue reported in the same quarter a year ago, and 48.2 percent last quarter.  Compared to the year ago quarter, gross profit percentage increased primarily due to lower manufacturing costs and benefits associated with a weaker Japanese yen versus the U.S. dollar, partially offset by lower sales volume.  The increase in gross profit percentage versus the previous quarter was primarily due to lower fixed manufacturing and logistics costs, and the favorable impact of the weaker Japanese yen.  Year to date, gross profit represented 48.3 percent of revenue, which is above the company's full fiscal year guidance range of 46 to 48 percent of revenue, which remains unchanged.

Operating expenses, which include research, development and technical, selling and marketing, and general and administrative expenses, were $32.4 million in the third fiscal quarter, or $1.2 million less than the $33.6 million reported in the same quarter a year ago, primarily due to lower depreciation expense, clean room materials expense and staffing related expenses.  Operating expenses were $2.0 million lower than the $34.4 million reported in the previous quarter, primarily due to lower staffing related costs.  Year to date, total operating expenses were $100.2 million.  The company's full year guidance for operating expenses remains unchanged at $132 million to $136 million.

Net income for the quarter was $15.5 million, or 17.0 percent higher than the $13.2 million reported in the same quarter last year, and 64.5 percent higher than the $9.4 million in the previous quarter.  Compared to the same quarter last year, net income was higher primarily due to a higher gross profit margin, a favorable impact of the weaker Japanese yen reflected in other income, lower operating expenses, and a lower effective tax rate, partially offset by lower revenue.  The effective tax rate in the third fiscal quarter decreased primarily due to the company's recent election to permanently reinvest the earnings of its Japan subsidiaries.  Compared to the prior quarter, net income was up $6.1 million mainly due to the company's higher level of sales, higher gross profit margin, lower operating expenses and a lower effective tax rate.  Year to date, net income of $34.6 million was up 18.6 percent compared to the prior year.

Diluted earnings per share were $0.65 this quarter, which includes a $0.05 benefit associated with the company's permanent reinvestment election in Japan, up from $0.55 reported in the third quarter of fiscal 2012 and up from $0.40 reported in the previous quarter.  Year to date, diluted earnings per share of $1.46 were up 17.7 percent compared to last year.
