Lam Research Corporation Announces Earnings for the Quarter Ended March 30, 2008

FREMONT, Calif., April 23, 2008 - Lam Research Corporation (NASDAQ: LRCX) highlights for the March 2008 quarter were:

Lam Research Corporation today announced earnings for the quarter ended March 30, 2008. Revenue for the period was $613.8 million, gross margin was $287.2 million and net income was $103.5 million, or $0.82 per diluted share, compared to revenue of $610.3 million, gross margin of $307.7 million and net income of $115.1 million, or $0.91 per diluted share for the December 2007 quarter.

The earnings of the SEZ Group, after the March 11, 2008 acquisition date, have been consolidated into the March 2008 quarter results. The Company has decided to adopt an acceptance-based revenue recognition model for the SEZ Group, now known as the Spin Clean Division, which has the effect of deferring almost all of the post-acquisition March quarter Spin Clean Division revenues and the related cost of sales to a future period. Accordingly, Spin Clean Division revenues were limited to $1.7 million, and after operating expenses and an in-process research and development write-off related to the acquisition, the resulting U.S. Generally Accepted Accounting Principles ("U.S. GAAP") loss was $5.6 million after taxes.

The Company's ongoing results for the March 2008 quarter exclude certain costs related to the recent acquisition of the SEZ Group, including the foreign currency gains associated with the acquisition and the one-time charge for in-process research and development expense. In addition, the Company's ongoing results for the March 2008 and December 2007 quarters exclude the costs associated with its voluntary internal stock option review. Management uses the presentation of ongoing gross margin, ongoing operating income, ongoing net income, and ongoing diluted earnings per share to evaluate the Company's operating and financial results. The Company believes the presentation of ongoing results is useful to investors for analyzing ongoing business trends and comparing performance to prior periods, and enhances the investor's ability to view the Company's results from management's perspective. A table presenting a reconciliation of ongoing results to results under U.S. GAAP is included at the end of this press release and on the Company's web site.

Ongoing net income was $109.8 million, or $0.87 per diluted share in the March 2008 quarter compared to ongoing net income of $118.9 million, or $0.94 per diluted share, for the December 2007 quarter. Ongoing gross margin for the March 2008 quarter slightly exceeded the Company's expectations and was $293.6 million or 47.8% compared to ongoing gross margin of $307.7 million, or 50.4%, for the December 2007 quarter. The majority of the sequential decline was due to unfavorable customer and product mix. Ongoing operating expenses of $148.9 million for the March 2008 quarter were higher than the December 2007 quarter of $140.0 million, primarily due to the inclusion of the Spin Clean Division operating expenses and to a lesser extent higher employee compensation costs at the Company.

The geographic distribution of shipments and revenue during the March 2008 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 the March 2008 quarter, including approximately $0.2 billion attributed to the Spin Clean Division. Deferred revenue and deferred profit balances were $270.1 million and $162.1 million, respectively. At the end of the March 2008 period, the anticipated future revenue value of orders shipped to Japanese customers that is not recorded as deferred revenue was approximately $43 million.

"Lam's March quarter performance met or slightly exceeded our expectations for shipments, revenues, gross margins and operating income. The headwind of the current economic environment creates challenges for us and many other semiconductor equipment manufacturers in the upcoming quarters, but we believe that our intense focus on creating yield enabling solutions in etch and clean coupled with our investment in long-term new market opportunities, has Lam Research well positioned to resume a strong growth trajectory when our customers recommence increased wafer fabrication equipment spending," said Steve Newberry, Lam Research's president and chief executive officer.

"Our acquisition of the SEZ Group is a significant milestone on our path to become a multi-market, $4+ billion dollar revenue company targeted for calendar year 2010. I am encouraged by the enthusiasm of the Clean Group employees in their initial collaboration efforts, particularly at the customer interface, where we now offer the broadest set of single-wafer wet clean solutions. Our partnership in R&D, where the sharing of process and hardware knowledge offers exciting opportunities, is already extremely active. Taken together, these elements reinforce our belief in the strategic merit of the acquisition. I want to convey appreciation to all employees for their continued hard work in facilitating the next leg of growth for Lam Research," Newberry concluded.
