FREMONT, Calif., July 24, 2007 ?Lam Research Corporation (NASDAQ: LRCX) today announced selected financial results for the quarter ended June 24, 2007.

Revenue for the period was $678.5 million compared to revenue of $650.3 million for the March 2007 quarter. Shipments for the June 2007 quarter were approximately $694 million compared to March 2007 quarter shipments of approximately $620 million.

The geographic distribution of shipments and revenue during the June 2007 quarter is shown in the following table:

Cash and cash equivalents, short-term investments and restricted cash and investments balances were $1.0 billion at the end of June. The Company repurchased approximately $768 million of its common stock during the quarter resulting in the completion of the Company's currently available repurchase authorizations. During the June 2007 quarter, capital expenditures were approximately $14 million and proceeds from the issuance of common stock related to employee equity-based plans were $19 million. Total shares outstanding as of June 24, 2007 were 123,535,328. At the end of the period, deferred revenue was $295.5 million and the anticipated future revenue value of orders shipped to Japanese customers that are not recorded as deferred revenue was approximately $51.1 million.

"Our strong shipment and revenue performance for the June quarter is indicative of continued operational and financial execution at Lam Research," said Steve Newberry, Lam Research's president and chief executive officer. "While the near term environment is expected to be characterized by a slowing of the rate of capacity expansion in memory, we believe the long-term semiconductor unit demand outlook remains favorable and that Lam is in excellent position to execute on its strategic objectives of maintaining and building on its existing leadership positions in its core etch business; expanding its served available market through entry into markets adjacent to etch, and delivering strong cash flows," Newberry concluded.
