FOR IMMEDIATE RELEASE
KLA-TENCOR ANNOUNCES LIVE WEBCAST OF
UPCOMING QUARTERLY CALL
UPCOMING QUARTERLY CALL
SAN JOSE, Calif., July 21, 2006—KLA-Tencor Corp. (Nasdaq: KLAC), the world leader in yield
management and process control solutions for semiconductor manufacturing and related
industries, today announced that the company will provide a live webcast of its upcoming
fourth quarter fiscal 2006 conference call, scheduled for Thursday, July 27, 2006, at 2:00
p.m. (PT).
As previously announced, the Company’s Board of Directors has appointed a Special Committee
of independent directors to conduct an internal investigation relating to stock options
granted to the employees of the Company. As disclosed on June 30, the Special Committee
has reached a preliminary conclusion that the actual measurement dates for financial
accounting purposes of certain stock option grants issued in prior years likely differ from
the recorded grant dates of such awards. The Special Committee has not yet determined
whether any resulting compensation charges or tax implications are material or whether the
Company ultimately will restate previously issued financial statements.
As a result of the on-going investigation and the potential for restatement, the Company is
unable to provide detailed GAAP or non-GAAP financials for items other than revenue and
bookings for the quarter or year ended June 30, 2006. In addition, the Company will not
file its annual report on form 10-K until after the completion of the investigation. The
Company does not expect the investigation to be completed until after the date the Form
10-K is required to be filed.
The webcast will be available on KLA-Tencor’s website at http://www.kla-tencor.com, on the
Investors page.
