MKS Instruments to Update Revenue Outlook for Second Quarter 2011 during Today's Investor and Analyst Meeting

ANDOVER, Mass., June 15, 2011 /PRNewswire via COMTEX/ -- MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, will update its revenue outlook for the second quarter of 2011 in today's investor and analyst meeting.

In celebration of the 50th anniversary of the founding of the company, CEO and President Leo Berlinghieri will ring The NASDAQ Opening Bell this morning at 9:30 a.m. ET. Immediately following, the senior management team will host an investor and analyst meeting at The NASDAQ MarketSite in Times Square. A live and archived webcast, as well as presentation slides from the event, will be available on the company's website, http://www.mksinst.com/.

Commenting on the event, Leo Berlinghieri stated, "We are hosting an investor and analyst meeting at the NASDAQ in New York that coincides with our 50th anniversary celebration. As this investor event takes place late in the quarter, we have a clearer view of the near-term business outlook and are in a position to update our expectations for second quarter revenues.

"As is well understood among our investors and analysts, following our April 21st conference call discussing first quarter 2011 financial results, several of our semiconductor OEM customers commented on shifts in the timing of shipments and orders among their customer base. Not surprisingly, these shifts have been reflected in our customers' ordering patterns and we currently expect June quarter revenues to be around the lower end of our prior guidance of $220 to $240 million. The impact of our semiconductor customers' ordering plans has been relatively modest and, as I commented last week, I am pleased to be celebrating our 50th anniversary after a record-setting 2010 and within what is shaping up to be an even stronger 2011."
