PALO ALTO, Calif., March 29, 2012 – TIBCO Software Inc. (NASDAQ: TIBX) today announced results for its first fiscal quarter, which ended on Sunday, March 4, 2012.

Total revenue for the first quarter of fiscal 2012 was $225.7 million and net income was $20.6 million, or $0.12 per diluted share. This compares to total revenue of $185.3 million and net income of $16.0 million, or $0.09 per diluted share, as reported for the first quarter of fiscal 2011.

On a non-GAAP basis, net income for the first quarter of fiscal 2012 was $34.6 million or $0.20 per diluted share, compared with $27.3 million or $0.16 per diluted share for the first quarter of fiscal 2011. Non-GAAP operating income for the first quarter of fiscal 2012 was $47.6 million, an increase of 17% over non-GAAP operating income of $40.5 million in the first quarter of fiscal 2011.

About Non-GAAP Financial Measures

TIBCO provides non-GAAP measures for operating income, net income and net income per share data as supplemental information regarding TIBCO’s business performance. TIBCO believes that these non-GAAP financial measures are useful to investors because they exclude non-operating charges. TIBCO’s management excludes these non-operating charges when it internally evaluates the performance of TIBCO’s business and makes operating decisions, including internal budgeting, performance measurement and the calculation of bonuses and discretionary compensation, because these measures provide a consistent method of comparison to historical periods. Moreover, management believes these non-GAAP measures reflect the essential revenue generation activities of TIBCO. Accordingly, management excludes stock-based compensation related to employee stock options, amortization of acquired intangible assets, costs related to formal restructuring activities, acquisition-related and other expenses, gains and losses on equity investments, and the income tax effects of the foregoing, as well as adjustments for the impact of changes in the valuation allowance recorded against TIBCO’s deferred tax assets when making operational decisions.

TIBCO believes that providing the non-GAAP measures that management uses to its investors is useful to investors for a number of reasons. The non-GAAP measures provide a consistent basis for investors to understand TIBCO’s financial performance on a trended basis across historical periods. In addition, it allows investors to evaluate TIBCO’s performance using the same methodology and information as that used by TIBCO’s management.

Non-GAAP measures are subject to material limitations as these measures are not in accordance with, or a substitute for, GAAP and thus TIBCO’s definition may be different from similar non-GAAP measures used by other companies and/or analysts. However, TIBCO’s management compensates for these limitations by providing the relevant disclosure of the items excluded in the calculation of non-GAAP operating income, non-GAAP net income and non-GAAP net income per share. In addition, some items such as restructuring charges that are excluded from non-GAAP net income and non-GAAP earnings per share can have a material impact on cash flows and stock compensation charges can have a significant impact on earnings. Management compensates for these limitations by evaluating the non-GAAP measure together with the most directly comparable GAAP measure. TIBCO has historically provided non-GAAP measures to the investment community as a supplement to its GAAP results, to enable investors to evaluate TIBCO’s business performance in the way that management does.

The non-GAAP adjustments, and the basis for excluding them, are outlined below:

Amortization of Intangible Assets

TIBCO has incurred amortization of intangible assets, included in its GAAP financial statements, related to various acquisitions TIBCO has made. Management excludes these items, for the purposes of calculating non-GAAP operating income, non-GAAP net income and non-GAAP net income per share. TIBCO believes that eliminating this expense from its non-GAAP measures is useful to investors, because the amortization of intangible assets can be inconsistent in amount and frequency and is significantly impacted by the timing and magnitude of TIBCO’s acquisition transactions, which also vary substantially in frequency from period to period.

Stock-based Compensation

TIBCO incurs stock-based compensation expense. TIBCO excludes this item for the purposes of calculating non-GAAP operating income, non-GAAP net income and non-GAAP net income per share because it is a non-cash expense that TIBCO believes is not reflective of its business performance. The nature of the stock-based compensation expense also makes it very difficult to estimate prospectively, since the expense will vary with changes in the stock price and market conditions at the time of new grants, varying valuation methodologies, subjective assumptions and different award types, making the comparison of current results with forward-looking guidance potentially difficult for investors to interpret. The tax effects of stock-based compensation expenses may also vary significantly from period to period, without any change in underlying operational performance, thereby obscuring the underlying profitability of operations relative to prior periods. Finally, TIBCO believes that non-GAAP measures of profitability that exclude stock-based compensation are widely used by analysts and investors in the software industry.

Acquisition-related and Other Expenses

TIBCO has incurred acquisition-related and other expenses which consist of costs incurred after the issuance of a definitive term sheet for a particular transaction (whether or not such transaction is ultimately completed, remains in process or is not completed) and include legal, banker, accounting and other advisory fees of third parties and severance costs for employees of the acquired company that are terminated within 90 days of the acquisition date. Management excludes these items, for the purposes of calculating non-GAAP operating income, non-GAAP net income and non-GAAP net income per share. TIBCO believes that eliminating these expenses from its non-GAAP measures is useful to investors, because it generally would not have otherwise incurred such expenses in the periods presented as part of its continuing operations. The acquisition-related and other expenses are not recurring with respect to past transactions, can be inconsistent in amount and frequency from period to period and are significantly impacted by the timing and magnitude of TIBCO’s acquisitions. While these expenses are not recurring with respect to past transactions, TIBCO generally will incur these expenses in connection with any future acquisitions.

Restructuring Activities

TIBCO has incurred restructuring expenses, included in its GAAP presentation of operating expense, primarily due to workforce related charges such as payments for severance and benefits and estimated costs of exiting and terminating facility lease commitments related to a formal restructuring plan. TIBCO excludes these items, for the purposes of calculating non-GAAP operating income, non-GAAP net income and non-GAAP net income per share, when it evaluates the continuing business performance of TIBCO. TIBCO believes that these items are not consistently recurring and do not necessarily reflect expected future operating expense, nor does TIBCO believe that they provide a meaningful evaluation of current versus past business results or the expense levels required to support TIBCO’s operating plan.
