Use of Non-GAAP Financial Information

This press release includes the following supplemental non-GAAP financial measures: non-GAAP gross profit, non-GAAP operating income, non-GAAP net income and non-GAAP net income per diluted share. The presentation of this supplemental non-GAAP financial information, which is not prepared under any comprehensive set of accounting rules or principles, is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with generally accepted accounting principles. In addition, these measures may be materially different from non-GAAP financial measures used by other companies. Wind River is providing these non-GAAP financial measures because it believes that such measures provide important supplemental information to management and investors about the company’s core operating results, primarily because the non-GAAP measures exclude certain expenses and other amounts that management does not consider to be indicative of the company’s core operating results or business outlook. Wind River management uses these non-GAAP financial measures, in addition to the corresponding GAAP financial measures, in evaluating the company’s operating performance, in planning and forecasting future periods, in making decisions regarding business operations and the allocation of resources, and in comparing the company’s performance against its historical performance. For a description of these non-GAAP financial measures, including the reasons management uses these measures, and reconciliations of these non-GAAP financial measures to the most directly comparable financial measures prepared in accordance with GAAP, please see the following sections of this release entitled “About Non-GAAP Financial Measures” and “Reconciliation of GAAP to Non-GAAP Financial Measures.” All non-GAAP financial measures should be read in conjunction with the comparable information presented in accordance with GAAP. Unless specified otherwise in this release, all references to GAAP and non-GAAP net income (loss) per share are calculated on a fully-diluted basis.

WIND RIVER SYSTEMS, INC.

ABOUT NON-GAAP FINANCIAL MEASURES

In addition to the company’s condensed consolidated financial statements prepared in accordance with generally accepted accounting principles, or GAAP, Wind River is providing in this release certain supplemental non-GAAP measures of financial performance. These non-GAAP financial measures include: non-GAAP gross profit, non-GAAP operating income, non-GAAP net income and non-GAAP net income per diluted share. For a reconciliation of these non-GAAP financial measures to the most directly comparable financial measures prepared in accordance with GAAP, see the following section of this release entitled “Reconciliation of GAAP to Non-GAAP Financial Measures.”

The presentation of supplemental non-GAAP financial information, which is not prepared under any comprehensive set of accounting rules or principles, is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. In addition, these measures may be materially different from non-GAAP financial measures used by other companies.

Wind River is providing these non-GAAP financial measures because it believes that such measures provide important supplemental information to management and investors about the company’s core operating results, primarily because the non-GAAP measures exclude certain expenses and other amounts that management does not consider to be indicative of the company’s core operating results or business outlook. Wind River management uses these non-GAAP financial measures, in addition to the corresponding GAAP financial measures, in evaluating the company’s operating performance, in planning and forecasting future periods, in making decisions regarding business operations and the allocation of resources, and in comparing the company’s performance against its historical performance. Wind River excludes the following items from its non-GAAP financial measures:

Stock-based compensation expense. The company’s non-GAAP financial measures exclude stock-based compensation expense related to the grant of stock options, other related instruments and restricted stock issued in the Interpeak acquisition. While stock-based compensation is a significant expense affecting the company’s results of operations, management excludes stock-based compensation from its budget and operating decision-making processes because it believes that these non-cash expenses do not reflect the company’s ongoing operating results. Since stock-based compensation expense is excluded from non-GAAP financial measures, the company also excludes unamortized stock-based compensation in its computation of non-GAAP dilutive shares, which generally decreases the weighted number of buyback shares under the treasury stock method.

Amortization of purchased and other intangible assets. In accordance with GAAP, Wind River incurs expenses for the amortization of purchased and other intangibles resulting from prior acquisitions. These charges are not factored into management’s evaluation of potential acquisitions, or our performance after completion of acquisitions, because they are not related to our core operating performance. In addition, the frequency and amount of such charges vary significantly based on the size and timing of our acquisitions and the maturities of the businesses being acquired. Excluding this data provides investors with a basis to compare the company against the performance of other companies without this variability.

Other costs. Wind River excludes amounts from non-GAAP financial measures related to restructuring and other charges, employer payroll taxes on stock option exercises, acquisition related costs and impairments on investments. The company excludes such costs because management believes that they are not related to the company’s core operating results and because the frequency and variability in the nature and amount of the charges can vary significantly from period to period.

Income tax related to non-GAAP items. In order to present full non-GAAP results, the company adjusts its provision for income taxes to reflect the tax effects of excluding the non-GAAP items noted above. In addition, the company includes the associated tax benefit related to stock option net operating losses and excludes amounts in its non-GAAP financial measures related to the establishment or reversal of income tax valuation allowances as management believes that such amounts are not indicative of the company’s ongoing business operating results and they are not included in budget or planning processes.

All supplemental non-GAAP financial measures should be read in conjunction with the comparable information presented in accordance with generally accepted accounting principles in the United States.
