Filed by Synopsys, Inc. Pursuant to Rule 425 under the Securities Act of 1933 and deemed filed pursuant to Rule 14a-12 of the Securities Exchange Act of 1934 Subject Company: Avant! Corporation File No. 333-75638 The following press release was issued by Synopsys, Inc. on May 6, 2002. CONTACT: Steve Shevick Vice President, Investor Relations Synopsys, Inc. 650-584-4880 Synopsys Expects Second Quarter Fiscal Year 2002 Earnings and Revenue Above Estimates MOUNTAIN VIEW, California. May 6, 2002 - Synopsys Inc., (Nasdaq: SNPS), the technology leader for complex integrated circuit design, today announced preliminary revenue and earnings before goodwill (EBG) results for the second quarter of fiscal year 2002, which ended on Saturday, May 4, 2002. Synopsys announced that it expects second quarter fiscal year 2002 EBG to be approximately $0.38 per share, two cents per share above the First Call(R) consensus estimate of $0.36 per share, and that it expects revenue for the quarter to be approximately $185 - $186 million, approximately $1 million above the consensus estimate. EBG represents earnings on a diluted basis excluding amortization of intangible assets and in-process research and development. Orders meaningfully exceeded the Company's expectations for the quarter, increasing approximately 20% over the second quarter of fiscal year 2001 and approximately 85% over the first quarter of fiscal year 2002. Orders for perpetual licenses were approximately 21%-22% of total software orders, within the anticipated range for the quarter. "This was a very good quarter for us, though the market remains difficult and the electronics industry continues to struggle," said Aart de Geus, Chairman and Chief Executive Officer of Synopsys. "Even in uncertain economic times, customers continue to invest in design technologies and buy from their critical technology partners, and our physical synthesis products enjoyed their best quarter ever. We are excited to be heading towards the completion of our merger with Avant!, and the realization of our vision of bringing together the best front end and the best back end design tools in the industry. Based on our results, and the record revenue and earnings announced last week by Avant!, we believe that the combined company will have strong product and financial momentum from day one." In connection with the merger, Synopsys indicated that it expected to recognize as revenue approximately 70-80% of Avant!'s aggregate deferred revenue and backlog, assuming fulfillment by the combined company of the commitments represented by such deferred revenue and backlog. Avant!'s aggregate deferred revenue and backlog will be determined at closing; revenue will be recognized as products and services are delivered and payments become due. Synopsys further noted that its proposed accounting treatment of deferred revenue and backlog had been confirmed by the Securities and Exchange Commission. Detailed financial guidance for the combined company will be provided after the close of the merger; both companies' shareholder meetings are scheduled for June 4, 2002. Synopsys cautioned that these anticipated results are preliminary, based on the best information currently available, and are subject to the closing of its books and customary quarterly accounting procedures.
