Lam Research Files Financial Statements with the SEC

FREMONT, Calif.--(Business Wire)--
Lam Research Corporation (NASDAQ:LRCX) today announced that the
Company has filed its fiscal year 2007 Form 10-K, September 2007 Form
10-Q and December 2007 Form 10-Q, with the Securities and Exchange
Commission (SEC). The Company believes it is now current with its SEC
filings and is awaiting confirmation from NASDAQ that it has complied
with all applicable listing standards.

As previously announced, the independent committee appointed by
Lam's Board of Directors determined that the actual measurement dates
for financial accounting purposes of certain stock option grants
differed from the recorded grant dates of these awards. As a result
the Company has recorded adjustments to previously issued financial
statements totaling $65.8 million for compensation expenses, net of
taxes, in fiscal years 1997 through 2006, with a $3.0 million impact
on the three most recent fiscal years. In addition, Lam Research
expects to incur a cash expense currently estimated at $50.0 - $55.0
million which will be recorded in the March 2008 quarter, as a result
of the Board's decision authorizing the Company to assume
responsibility for the 409A tax liabilities of employees.

Lam Research anticipates the Company will resume communication of
full quarter financial results in its next quarterly conference call
on April 23, 2008.

Statements made in this press release which are not statements of
historical fact are forward-looking statements and are subject to the
safe harbor provisions created by the Private Securities Litigation
Reform Act of 1995. Such forward-looking statements relate, but are
not limited to, the resumed communication of full financial results in
April of 2008, and compliance with the applicable listing standards of
NASDAQ. Important factors that could cause actual results to differ
materially from those in the forward-looking statements include,
without limitation, the discovery of new facts relating to the
Company's stock option grants, receipt of approvals from third parties
such as our independent registered accounting firm, of those financial
results, and the determination by NASDAQ that the Company is in
compliance with the applicable listing standards. These
forward-looking statements are based on current expectations and are
subject to uncertainties and changes in condition, significance, value
and effect as well as other risks detailed in documents filed with the
Securities and Exchange Commission, including specifically the report
on Form 10-K for the year ended June 24, 2007, and Form 10-Q for the
quarter ended December 23, 2007, which could cause actual results to
vary from expectations. The Company undertakes no obligation to update
the information or statements made in this press release.
