Cadence Announces Accounting Review and Postpones Release of Third Quarter 2008 Financial Results and Webcast

Reaffirms Third Quarter 2008 Guidance

SAN JOSE, Calif. -- Oct 22, 2008 -- Cadence Design Systems, Inc. (NASDAQ: CDNS) today announced that it is reviewing, in conjunction with the company’s independent accountants and legal advisors, the recognition of revenue related to customer contracts signed during the first quarter of 2008.

Cadence initiated the review after preliminarily determining during its regular review of its third quarter results that approximately $24 million of revenue relating to these contracts was recognized during the first quarter of 2008, but should have been recognized ratably over the duration of the contracts commencing in the second quarter of 2008. Cadence expects to restate its financial statements for the first quarter of 2008 and the first half of 2008 to correct the revenue recognition with respect to these contracts.

Cadence will release its third quarter 2008 financial results and conduct a Webcast as soon as practicable.

Reaffirmation of Expected Third Quarter Results

Cadence reaffirms the expected third quarter 2008 results provided in its press release of October 15, 2008. For the third quarter of 2008, the company expects results to be in line with the business outlook previously announced on July 23, 2008. Total revenue is estimated to be in the range of $235 to $245 million. Third quarter GAAP net loss per share is estimated to be in the range of $(0.27) to $(0.25). Net loss per share using the non-GAAP measure defined below is estimated to be in the range of $(0.11) to $(0.09). These results are preliminary and subject to the company's management completing its quarterly close. In addition to using GAAP results in evaluating Cadence’s business, management believes it is useful to measure results using a non-GAAP measure of net income, which excludes, as applicable, amortization of intangible assets, stock-based compensation expense, in-process research and development charges, certain termination and legal costs, integration and acquisition-related costs, gains or losses and expenses or credits related to non-qualified deferred compensation plan assets, executive severance payments, restructuring charges and credits, losses on extinguishment of debt and equity in losses (income) from investments. Non-GAAP net income is adjusted by the amount of additional taxes or tax benefit that the company would accrue if it used non-GAAP results instead of GAAP results to calculate the company’s tax liability. Investors and potential investors are encouraged to review the reconciliation of non-GAAP financial results with their most direct comparable GAAP financial results, including the reconciliation of non-GAAP financial results with GAAP financial results for the quarter ended June 28, 2008 set forth in our press release of July 23, 2008, which can be found in the investor relations portion of our website at www.cadence.com/cadence/investor_relations.
