                 Mentor Graphics Updates 2005 Outlook

    WILSONVILLE, Ore.--(BUSINESS WIRE)--April 27, 2005--Mentor
Graphics Corporation (Nasdaq:MENT) today updated 2005 guidance. While
weakness experienced in the first quarter is expected to continue
through the second quarter of 2005, the company anticipates the second
half of 2005 will remain at previously guided revenues and earnings,
based on a healthy number of contract renewals due in the fourth
quarter.
    For the second quarter, revenues are expected to be approximately
$155 million with pro forma earnings per share ranging between a loss
of $.10 and break-even, with a GAAP loss of between $.14 and $.04 per
share. In the third quarter, revenues are expected to be approximately
$180 million and pro forma earnings per share of approximately $.10,
with GAAP earnings per share of about $.06. For the fourth quarter,
revenues should be approximately $226 million with pro forma earnings
per share of about $.54 and GAAP earnings per share of about $.49.
    For the full year 2005, we expect revenues of about $725 million,
a 2% growth from 2004. Pro forma earnings are anticipated to range
between $.55 and $.65. GAAP earnings per share are expected to range
between $.36 and $.46.

    In the calculation of pro forma earnings, gross margin and
operating expenses, Mentor Graphics excludes amortization of acquired
intangibles and write-offs of in-process R&D from acquisitions.
Included in pro forma earnings was a $1million gain related to the
sale of a building classified in other income, net. Also, excluded are
non-operating and non-recurring items classified as special charges
such as restructure expenses and asset impairments, as well as income
tax expense in excess of a normalized 17% effective tax rate. These
excluded items are generally infrequent, less predictable and are
often non-cash in nature. Mentor Graphics believes that excluding
these items provides investors with a representation of its core
performance, and a pro forma base line for assessing the future
earnings potential of Mentor Graphics.
    These pro forma measures should be assessed in conjunction with
GAAP earnings measures for a more complete understanding of the
Company's results. Since pro forma measures exclude certain items,
differences in earnings from GAAP can be significant; Mentor Graphics
management evaluates its performance under both measures for a
complete understanding of its results. Investors are encouraged to
review both measures for their evaluations and consider the GAAP
earnings measures as the most complete measure of Mentor Graphics'
overall performance.
