Mentor Graphics Announces First Quarter Results

WILSONVILLE, Ore. April 27, 2005 - Mentor Graphics Corporation (Nasdaq: MENT) today announced first quarter revenues of $164.3 million, approximately flat with the year ago quarter. GAAP earnings per share were a loss of $.06, while pro forma earnings per share were $.01, consistent with the company's pre-announcement of April 4, 2005.

"Weakness in the business was driven primarily by softness in demand from semiconductor companies, while demand from system businesses was better. As a result, Mentor systems products like FPGA synthesis, embedded software and selected PCB products performed well," said Walden C. Rhines, CEO and chairman of Mentor Graphics. "On the other hand, Calibre product line bookings were particularly weak in the quarter. We expect strength in this product line in the second half of the year based upon the number of current customer engagements."

The Scalable Verification product line was also down, driven largely by a tough compare with the year ago quarter when the company's largest ever ModelSim order occurred.

"As the drive to time-based licensing continues, our business is increasingly driven into the fourth quarter," said Gregory K. Hinckley, president of Mentor Graphics. "While we are not satisfied with our first quarter performance, our second half continues to look solid."

Revenue by region was 45% North America, 25% Europe, 20% Japan and 10% Pacific Rim. By product line, revenue was 30% scalable verification, 25% integrated system design, 25% design to silicon, and 20% new and emerging products.

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.
