TIBCO SOFTWARE REPORTS Q2 GAAP EPS OF $0.06, NON-GAAP EPS OF $0.11

Q2 Non-GAAP Operating Profit Increases 56% Over Prior Year

PALO ALTO, Calif., June 25, 2009 – TIBCO Software Inc. (Nasdaq: TIBX) today announced results for its second fiscal quarter, which ended on May 31, 2009.

Total revenue for the second quarter of fiscal 2009 was $142.7 million, as compared to $150.0 million for the second quarter of fiscal 2008. On a constant currency basis, total revenue for fiscal Q2 grew year over year by approximately 1%. GAAP net income for Q2 was $10.1 million or $0.06 per diluted share, as compared to $3.5 million or $0.02 per diluted share reported for the second quarter of fiscal 2008. Using constant currency, earnings growth for Q2 was not significantly impacted by currency movements.

On a non-GAAP basis, net income for the second quarter of fiscal 2009 was $19.0 million or $0.11 per diluted share, compared with $12.4 million or $0.07 per diluted share for the second quarter of fiscal 2008. Non-GAAP operating income for the second quarter of fiscal 2009 was $27.1 million, resulting in a non-GAAP operating margin of 19%. This compares to non-GAAP operating income of $17.5 million, or a 12% non-GAAP operating margin in the second quarter of fiscal 2008. Non-GAAP results exclude stock-based compensation expense, amortization of acquired intangible assets, and assume a non-GAAP effective tax rate of 32% and 33% for the second quarters of fiscal 2009 and 2008, respectively.

“We are managing our business tightly during the downturn and focused on delivering strong returns, as shown by a 40% annual growth in non-GAAP EPS through the first half of the year,” said Vivek Ranadivé, TIBCO’s chairman and chief executive officer. “At the same time, we continue to innovate by investing in our core product lines and moving aggressively into emerging sectors such as cloud computing, as highlighted by our release this quarter of TIBCO Silver, the industry’s first cloud application delivery platform for the enterprise.”

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, charges for acquired in-process research and development, costs related to formal restructuring activities, 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:

Stock-based Compensation

TIBCO incurs stock-based compensation expense under SFAS 123(R). 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.

Amortization of Acquired 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.
