Entegris Reports Strong Third Quarter Results

Quarterly Sales of $178 million Marks Sixth Consecutive Quarter of
Growth;

Non-GAAP EPS of $0.18; Cash from Operations Exceeds $45 Million;

Adjusted Operating Margin Reaches 18 Percent

BILLERICA, Mass., Oct. 26, 2010 (GLOBE NEWSWIRE) -- Entegris, Inc. (Nasdaq:ENTG)
today reported its financial results for the Company's third quarter ended
October 2, 2010.

The Company recorded third-quarter sales of $178.2 million, an increase of 61
percent over the prior year, and 6 percent sequentially. Net income was $22.4
million, or $0.17 per diluted share. These results included amortization of
intangible assets of $2.8 million.

Non-GAAP earnings per share of $0.18 in the third quarter of 2010 compared to a
loss per share of $0.02 in the third quarter a year ago and earnings per diluted
share of $0.16 in the second quarter of 2010. A reconciliation table of GAAP to
non-GAAP earnings (loss) per share is contained in this press release.

For the first nine months of fiscal 2010, sales were $506.3 million, up 101
percent from the first nine months of 2009. Non-GAAP earnings per diluted share
for the first nine months of 2010 were $0.48 versus a loss per share of $0.43
for the same period a year ago.

Gideon Argov, president and chief executive officer, said: "Our third-quarter
results marked another quarter of growth and strong operating performance, as we
continue to execute our growth strategies and build shareholder value. Sales to
our core semiconductor market were strong, as our liquid filtration and gas
filtration businesses achieved record-level quarters. Across our portfolio of
technologies, we are capitalizing on an increasing number of opportunities with
our advanced filtration and microenvironment solutions to help fab customers
implement advanced sub-32 nanometer processes.

"Our adjusted operating margin was 18.0 percent, consistent with our target
operating model. This translated into another quarter of strong cash flow,
resulting in $45 million in cash from operations and $39 million of adjusted
EBITDA in the third quarter. Our net cash position is now approaching $100
million, well ahead of expectations. Thus far in the fourth quarter, demand from
our customers is stable, despite the uncertain outlook for global economic
recovery. Regardless of how this current industry cycle unfolds, we believe we
have the opportunity to outpace our markets," Argov said.

For the fiscal fourth quarter ending December 31, 2010, the Company expects
sales to range from approximately $173 million to $183 million. Based on the
Company's target model, non-GAAP net earnings per diluted share are expected to
range from $0.17 to $0.19.

Non-GAAP Information

The Company's consolidated financial statements are prepared in conformity with
accounting principles generally accepted in the United States (GAAP). Adjusted
EBITDA and Adjusted Operating Income together with related measures thereof, and
non-GAAP EPS, are considered "Non-GAAP financial measures" under the rules and
regulations of the SEC. These financial measures are provided as a complement to
financial measures provided in accordance with GAAP. We provide non-GAAP
financial measures in order to better assess and reflect operating performance.
Management believes the non-GAAP measures help indicate our baseline performance
before certain gains, losses or other charges that may not be indicative of our
business or future outlook. We believe these non-GAAP measures will aid
investors' overall understanding of our results by providing a higher degree of
transparency for certain expenses and providing a level of disclosure that will
help investors understand how we plan and measure our business. The presentation
of non-GAAP measures is not meant to be considered in isolation, as a substitute
for, or superior to, financial measures or information provided in accordance
with GAAP. The calculations of Adjusted EBITDA margin, Adjusted Operating
Income, and non-GAAP EPS are included elsewhere in this release.
