Cadence Reports Q3 2011 Financial Results

SAN JOSE, Calif. — October 26, 2011 — Cadence Design Systems, Inc. (NASDAQ: CDNS) today announced results for the third quarter of fiscal year 2011.

Cadence reported third quarter 2011 revenue of $292 million, compared to revenue of $238 million reported for the same period in 2010. On a GAAP basis, Cadence recognized net income of $28 million, or $0.10 per share on a diluted basis in the third quarter of 2011, compared to net income of $127 million, or $0.48 per share on a diluted basis in the same period in 2010. GAAP net income for the third quarter of 2010 included $148 million in income tax benefit related to the settlement of an Internal Revenue Service examination of Cadence’s federal income tax returns for the tax years 2000 through 2002.

Using Cadence’s non-GAAP measure, net income in the third quarter of 2011 was $37 million, or $0.14 per share on a diluted basis, as compared to net income of $11 million, or $0.04 per share on a diluted basis in the same period in 2010.

“Strong design activity in multiple market segments continues to drive demand for our products and solutions,” said Lip-Bu Tan, president and chief executive officer. “In response to customer requirements, we have established our readiness for 20-nanometer design and demonstrated product leadership for the design of SoCs using advanced multi-core processors.”

“Cadence again posted strong results as operating profitability continues to improve,” added Geoff Ribar, senior vice president and chief financial officer. “Given the risks in the world economy we looked at our prospective Q4 business very closely but still see good demand for products and services as reflected in our increased outlook.”

In addition to using GAAP results to evaluate 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, integration and acquisition-related costs including changes in the fair value of contingent consideration related to prior acquisitions, acquisition-related income tax benefits, income tax benefits related to the

1

settlement of IRS examinations, shareholder litigation costs and charges, gains or losses and expenses or credits related to non-qualified deferred compensation plan assets, executive and other employee severance costs, restructuring charges and credits, amortization of discount on convertible notes, losses on extinguishment of debt, equity in losses or income from investments, write-down of investments, and gains or losses on the sale of 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. See “GAAP to non-GAAP Reconciliation” below for further information on the non-GAAP measure.

The following statements are based on current expectations. These statements are forward-looking, and actual results may differ materially.

Business Outlook

For the fourth quarter of 2011, the company expects total revenue in the range of $295 million to $305 million. Fourth quarter GAAP net income per diluted share is expected to be in the range of $0.08 to $0.10. Net income per diluted share using the non-GAAP measure defined below is expected to be in the range of $0.14 to $0.16.

For 2011, the company expects total revenue in the range of $1,135 million to $1,145 million. On a GAAP basis, net income per diluted share for 2011 is expected to be in the range of $0.31 to $0.33. Using the non-GAAP measure defined below, net income per diluted share for 2011 is expected to be in the range of $0.48 to $0.50.

A schedule showing a reconciliation of the business outlook from GAAP net income and diluted net income per share to non-GAAP net income and diluted net income per share is included with this release.

GAAP to non-GAAP Reconciliation

Cadence management evaluates and makes operating decisions using various operating measures. These measures are generally based on the revenues of its product, maintenance and services business operations and certain costs of those operations, such as cost of revenues, research and development, sales and marketing and general and administrative expenses. One such measure is non-GAAP net income, which is a non-GAAP financial measure under Section 101 of Regulation G under the Securities Exchange Act of 1934, as amended, and is GAAP net income excluding, as applicable, amortization of intangible assets, stock-based compensation expense, integration and acquisition-related costs, including changes in the fair value of contingent consideration related to prior acquisitions, acquisition-related income tax benefits, income tax benefits related to the settlement of IRS examinations, shareholder litigation costs and charges, gains or losses and expenses or credits related to non-qualified deferred compensation plan assets, executive and other employee severance costs, restructuring charges and credits, amortization of discount on convertible notes, losses on extinguishment of debt, equity in losses or income from investments, write-down of investments and gains or losses on the sale of investments. Intangible assets consist primarily of purchased or licensed technology, backlog, patents, trademarks, distribution rights, customer contracts and related relationships and non-compete agreements. 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.

Cadence’s management believes it is useful in measuring Cadence’s operations to exclude amortization of intangible assets and integration and acquisition-related costs, including changes in the fair value of contingent consideration related to prior acquisitions, because these costs are primarily fixed at the time of an acquisition and generally cannot be changed by Cadence’s management in the short term. In addition, Cadence’s management believes it is useful to exclude stock-based compensation expense because such exclusion enhances investors’ ability to review Cadence’s business from the same perspective as Cadence’s management, which believes that stock-based compensation expense is based on many subjective inputs at a point in time and many of these inputs are not necessarily directly attributable to the underlying performance of Cadence’s business operations. Cadence’s management also believes it is useful to exclude costs and charges related to shareholder litigation because these costs and charges are not related to Cadence’s core business operations. Cadence’s management also believes that it is useful to exclude restructuring charges and credits. During the fourth quarter of 2010, Cadence commenced a restructuring program and expects to have paid substantially all termination benefits and costs by the fourth quarter of 2011. Cadence’s management believes that in measuring the company’s operations, it is useful to exclude any such restructuring charges and credits because exclusion of such charges and credits permits consistent evaluations of Cadence’s performance before and after such actions are taken. Cadence’s management also believes it is useful to exclude gains or losses and expenses or credits related to the non-qualified deferred compensation plan assets because these gains or losses and expenses or credits are not part of Cadence’s direct costs of operations, but reflect changes in the value of assets held in the non-qualified deferred compensation plan. Cadence’s management also believes it is useful to exclude executive and other employee severance costs as these costs do not occur frequently. Cadence’s management also believes it is useful to exclude the amortization of the discount on convertible notes because this incremental cost recorded as interest expense does not represent a cash obligation of the company and is not part of Cadence’s direct cost of operations. Finally,

5

Cadence’s management believes it is useful to exclude the equity in losses or income from investments, write-down of investments and gains or losses on the sale of investments because these items are not part of Cadence’s direct cost of operations. Rather, these are non-operating items that are included in other income or expense and are part of the company’s investment activities.

During the second quarter of 2011, Cadence’s non-GAAP net income also excluded the effect of an income tax benefit associated with Cadence’s effective settlement of an Internal Revenue Services, or IRS, examination of Cadence’s federal income tax returns for the tax years 2003 through 2005. During the third quarter of 2010, Cadence’s non-GAAP net income also excluded the effect of an income tax benefit associated with Cadence’s effective settlement of an IRS examination of Cadence’s federal income tax returns for the tax years 2000 through 2002. Cadence’s management believes it is useful to exclude the income tax benefits associated with these settlements because exclusion of such tax benefits permits consistent evaluations of Cadence’s performance. Cadence does not expect settlements resulting in income tax provisions or benefits of the magnitude recorded during the third quarter of 2010 to occur frequently.

During the second and fourth quarters of 2010, Cadence’s non-GAAP net income also excluded losses associated with its repurchase of a portion of its 1.375% Convertible Senior Notes Due December 15, 2011 and a portion of its 1.500% Convertible Senior Notes Due December 15, 2013. Cadence’s management believes it is useful to exclude the losses on the extinguishment of debt as the losses are not directly related to Cadence’s core business operations and similar transactions are not expected to occur frequently.

During the second quarter of 2011, Cadence’s non-GAAP net income also excluded the effect of an income tax benefit associated with an acquisition Cadence completed during the second quarter of 2011. During the second quarter of 2010, Cadence’s non-GAAP net income also excluded the effect of an income tax benefit associated with Cadence’s acquisition of Denali Software, Inc. Cadence’s management believes it is useful to exclude the tax benefits associated with these acquisitions because exclusion of such tax benefits permits consistent evaluations of Cadence’s performance. Cadence does not expect an acquisition-related income tax benefit of the magnitude recorded in the second quarter of 2010 to be recorded frequently.

Cadence’s management believes that non-GAAP net income provides useful supplemental information to Cadence’s management and investors regarding the performance of the company’s business operations and facilitates comparisons to the company’s historical operating results. Cadence’s management also uses this information internally for forecasting and budgeting. Non-GAAP financial measures should not be considered as a substitute for or superior to measures of financial performance prepared in accordance with GAAP. Investors and potential investors are encouraged to review the reconciliation of non-GAAP financial measures contained within this press release with their most directly comparable GAAP financial results.

* Includes, as applicable, equity in losses or income from investments, write-down of investments, gains or losses on sale of investments and gains or losses on non-qualified deferred compensation plan assets recorded in Other income (expense), net.

** Shares used in the calculation of GAAP net income per share are expected to be the same as shares used in the calculation of non-GAAP net income per share, except when the company reports a GAAP net loss and non-GAAP net income, or GAAP net income and a non-GAAP net loss.

Investors are encouraged to look at the GAAP results as the best measure of financial performance. For example, amortization of intangibles is important to consider because it may represent an initial expenditure that under GAAP is reported across future fiscal periods. Likewise, stock-based compensation expense is an obligation of the company that should be considered. Restructuring charges can be triggered by acquisitions or product adjustments, as well as overall company performance within a given business environment. All of these metrics are important to financial performance generally.

Although Cadence’s management finds the non-GAAP measures useful in evaluating the performance of Cadence’s business, reliance on these measures is limited because items excluded from such measures often have a material effect on Cadence’s earnings and earnings per share

8

calculated in accordance with GAAP. Therefore, Cadence’s management typically uses the non-GAAP earnings and earnings per share measures, in conjunction with the GAAP earnings and earnings per share measures, to address these limitations.

Cadence expects that its corporate representatives will meet privately during the quarter with investors, the media, investment analysts and others. At these meetings, Cadence may reiterate the business outlook published in this press release. At the same time, Cadence will keep this press release, including the business outlook, publicly available on its website.

Prior to the start of the Quiet Period (described below), the public may continue to rely on the business outlook contained herein as still being Cadence’s current expectations on matters covered unless Cadence publishes a notice stating otherwise.

Beginning December 16, 2011, Cadence will observe a Quiet Period during which the business outlook as provided in this press release and the company’s most recent Annual Report on Form 10-K and Quarterly Report on Form 10-Q no longer constitute the company’s current expectations. During the Quiet Period, the business outlook in these documents should be considered to be historical, speaking as of prior to the Quiet Period only and not subject to any update by the company. During the Quiet Period, Cadence’s representatives will not comment on Cadence’s business outlook, financial results or expectations. The Quiet Period will extend until the day when Cadence’s Fourth Quarter 2011 Earnings Release is published, which is currently scheduled for February 1, 2012.
