    Guidance

AURORA, Ill., Jan. 24, 2013 (GLOBE NEWSWIRE) -- 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 first quarter
of fiscal 2013, which ended December 31, 2012.

Total revenue during the first fiscal quarter was $106.5 million, which
reflects an increase of 4.3 percent compared to the same quarter last year and
a decrease of 3.7 percent compared to the prior quarter. The company achieved
a gross profit margin of 47.0 percent of revenue in the first fiscal quarter
and diluted earnings per share of $0.41, which includes an adverse impact of
approximately $0.07 associated with a tax adjustment related to operations of
the company's facility in Korea since its opening in 2011. The company's
balance sheet reflects a cash balance of $169.6 million and $168.4 million of
debt outstanding as of December 31, 2012.

"I am encouraged with our first fiscal quarter financial results, which
reflect performance solidly in line with our expectations that were shaped by
persisting industry headwinds," said William Noglows, Chairman and CEO of
Cabot Microelectronics. "Though we experienced soft industry conditions,
continued macroeconomic uncertainty and the usual seasonality during the
quarter, we achieved revenue increases in both our core CMP slurry and pad
businesses compared to last year. Furthermore, our robust business model
enables us to successfully run our business over a range of market conditions,
and in the quarter we continued to prudently manage our operating costs and
generate a strong gross margin despite the slight sequential decline in demand
for our CMP consumables products."

Mr. Noglows continued, "In the face of continued macroeconomic uncertainty,
the industry has shown positive trends including the continuing strong
adoption of mobile devices.In order to leverage this growth opportunity and
other positive long-term industry trends, we continue to partner with
semiconductor industry leaders to further develop innovative technology that
is vital to success in our business. Our focus on building our infrastructure
and presence in the Asia Pacific region has significantly advanced these
efforts.With continuing softness in the industry in the near term, we believe
our ability to partner with our customers and leverage our global capabilities
and CMP expertise positions us well for continued success as we further
develop reliable, cost-effective solutions."

Key Financial Information

Total first fiscal quarter revenue of $106.5 million represents a 4.3 percent
increase from the $102.1 million reported in the same quarter last year and a
3.7 percent decrease from $110.6 million last quarter.The company believes
that the decrease in revenue from the prior quarter primarily reflects
continued soft demand within the global semiconductor industry that began to
appear late in the fourth fiscal quarter of 2012.

Gross profit, expressed as a percentage of revenue, was 47.0 percent this
quarter, which is at the midpoint of the company's guidance range of 46 to 48
percent of revenue for the full fiscal year.This is lower than the 48.3
percent reported in the same quarter a year ago and lower than 48.6 percent
last quarter.Compared to the year ago quarter, gross profit percentage
decreased primarily due to certain higher manufacturing costs and a lower
valued product mix, partially offset by higher sales volume.The decrease in
gross profit percentage versus the previous quarter was primarily due to
higher variable manufacturing costs and lower manufacturing yields, partially
offset by lower fixed manufacturing costs and a higher valued product mix.

Operating expenses, which include research, development and technical, selling
and marketing, and general and administrative expenses, were $33.4 million in
the first fiscal quarter, representing a 1.8 percent decrease from $34.0
million in the same quarter a year ago.The decrease was driven primarily by
the absence of professional fees related to the company's leveraged
recapitalization with a special cash dividend that it executed during fiscal
2012.Operating expenses were $0.1 million higher than the $33.3 million
reported in the previous quarter.

Net income for the quarter was $9.7 million, down from $10.4 million reported
in the same quarter last year and down from $11.6 million in the prior
quarter.Compared to the same quarter last year, net income was lower
primarily due to a $1.7 million adverse tax adjustment associated with
operations of the company's facility in Korea since its opening in 2011, and
higher interest expense, partially offset by higher revenue, foreign exchange
gains and lower operating expenses.Compared to the prior quarter, net income
was down mainly due to lower revenue and a lower gross profit margin,
partially offset by foreign exchange gains.

Diluted earnings per share were $0.41 this quarter, down from $0.45 reported
in the first quarter of fiscal 2012 and down from $0.49 reported in the
previous quarter.Earnings per share for the quarter were adversely impacted
by approximately $0.07 due to the referenced tax adjustment.
