• Fourth quarter total revenue of $16.9 million.

• Full year revenues of $68.8 million

• GAAP income from operations of $1.6 million, and net income of $1.2 million or $0.04 per diluted share for the fourth quarter.

• Non-GAAP income from operations of $3.0 million, and net income of $2.3 million or $0.09 per diluted share for the fourth quarter, above our guided range.

• Cash and cash equivalents of $62.4 million, no debt and $11.3 million of positive cash flow from operations for the year ended December 31, 2009.

Houston, Texas — February 11, 2010 — PROS Holdings, Inc. (NYSE: PRO), a leading provider of pricing and margin optimization science and software, today announced financial results for the fourth quarter ended December 31, 2009.

Total revenue for the fourth quarter of 2009 was $16.9 million, near the high end of the company’s guided range. License and implementation revenue was $10.3 million and maintenance and support revenue was $6.6 million. For the year ended December 31, 2009, revenue was $68.8 million, with 64% from license and implementation revenue and 36% from maintenance revenue.

Bert Winemiller, Chairman and CEO, stated, “We are pleased with our financial performance in the fourth quarter of 2009. We remain focused on our strategic goals of delivering significant value to our customers early in the implementation with a high return on investment and low total cost of ownership, while also scaling to meet the needs of the large long-term market opportunity. We are growing our pricing partner and influencer ecosystem as we expand our work with industry analysts, strategic consultants, technology providers and system integrators. We believe the market for pricing and margin optimization software is in the innovator early adopter stage. We also believe there are thousands of companies that would greatly benefit from our software with a current market penetration in the low single digits. While the macro economy continues to be challenging and forecasting for the longer-term remains difficult, we believe interest in PROS’ science-based pricing and margin optimization software continues to increase as sales-related activity levels continue to be very good and third party coverage of the power of pricing continues to reach a broader audience.”

For the quarter ended December 31, 2009, PROS reported income from operations, in accordance with generally accepted accounting principles (“GAAP”), of $1.6 million compared with $3.8 million in the fourth quarter of 2008. GAAP net income in the quarter was $1.2 million, or $0.04 per diluted share, compared with $3.6 million, or $0.14 per diluted share, in the fourth quarter of 2008.

For the quarter ended December 31, 2009, non-GAAP income from operations was $3.0 million compared with $4.9 million for the same period in 2008. Non-GAAP net income was $2.3 million, or $0.09 per diluted share, above the Company’s guided range, compared with non-GAAP net income of $4.6 million, or $0.17 per diluted share, in the fourth quarter of 2008. These non-GAAP results in the fourth quarter of 2009 and 2008 exclude $1.5 million and $1.1 million, respectively, of stock-based compensation charges.

For the year ended December 31, 2009, income from operations, in accordance with GAAP was $7.4 million compared with $13.9 million for the year ended December 31, 2008. GAAP net income for the year was $5.5 million, or $0.21 per diluted share, compared with $10.8 million, or $0.40 per diluted share, in 2008. Cash flow from operations was $11.3 million for the year ended December 31, 2009.

For the year ended December 31, 2009, non-GAAP income from operations was $12.8 million compared with $18.0 million for the year ended December 31, 2008. Non-GAAP net income for the year was $9.5 million, or $0.36 per diluted share, compared with $13.6 million, or $0.51 per diluted share, in 2008. These non-GAAP results for the year ended December 31, 2009 and 2008 exclude $5.5 million and $4.0 million, respectively, of stock-based compensation charges.

The effective tax rate was approximately 24% for the three months ended December 31, 2009 compared to an effective tax rate of approximately 9.0% for the three months ended December 31, 2008. The change in the tax rates was due to the timing of the reinstatement of the Research and Experimentation (“R&E”) tax credit which was not signed into law until October 2008. As a result, PROS recorded the full benefit of the R&E tax credit for 2008 in the fourth quarter of 2008. For the year ended December 31, 2009 and 2008, the effective tax rate was approximately 27% and 28%, respectively.

Charles Murphy, Executive Vice President and CFO, stated, “We are pleased to have recorded sequential revenue growth in the fourth quarter. Even in this challenging economy we were able to maintain a good level of profitability with non-GAAP operating margin of 18% for the quarter and 19% for the full year. Our strong balance sheet, with over $62 million in cash and no debt, and history of profitability and positive cash flow positions us favorably as customers consider vendor viability when making purchasing decisions. Our business trends are showing signs of stabilizing, but we believe it is too early to discern a significant upswing in our business environment.”

The attached table provides a reconciliation of GAAP to non-GAAP income from operations and net income as well as net income per share available to common stockholders for the year ended December 31, 2009 and 2008.

Financial Outlook

Based on information as of today, PROS is providing the following outlook for the first quarter of 2010:

First Quarter of Fiscal Year 2010:

• The Company expects total revenue in the range of $16.9 million to $17.3 million.

• The Company is projecting GAAP income from operations of $0.3 million to $0.7 million and GAAP diluted earnings per share of $0.01 to $0.02. Earnings per share are based on an estimated weighted average of 27.0 million diluted shares outstanding.

• The Company is projecting non-GAAP income from operations of $1.8 million to $2.2 million and non-GAAP diluted earnings per share of $0.05 to $0.06. Non-GAAP income from operations for the first quarter excludes estimated stock based compensation charges of approximately $1.5 million.

The projections provided above are based on an estimated tax rate of 30%. This rate assumes that Congress will reinstate on a retroactive basis the Research & Experimentation (“R&E”) tax credit. Congress has reinstated on a retroactive basis the R&E tax credit several times since its enactment in 1981, and PROS believes Congress will do so in 2010. However, until the credit is reinstated, PROS overall tax rate will be 37% to 38%. The impact of the R&E tax credit not being reinstated translates to a $0.01 diluted earnings per share impact for the first quarter of 2010 on a non-GAAP basis.

Backlog

Our backlog is derived from agreements that we believe to be firm to provide software products and related implementation and maintenance services in the future. Our backlog varies significantly period to period depending on a number of factors including the timing of our sales and the nature of the agreements we enter into with our customers. We typically do not recognize any revenue upon the signing of an agreement. Therefore, we do not seek to accelerate our sales processes around any reporting period.

Our backlog is also significantly based on estimates and judgments that we make regarding total contract values, requisite man-days to complete engagements and the value and number of man-days worked or expected to be worked in any particular period. For example, we could have agreements that include refund, delay or termination for convenience provisions, and we exercise judgment over the extent to which, if any, to include these agreements in our backlog. However, based on our history of successfully implementing our software products, we generally include the full estimated value of these agreements in backlog.

We make significant estimates and judgments regarding maintenance renewals and changes to existing maintenance agreements. Backlog includes committed maintenance amounts and amounts payable to us under maintenance agreements that we reasonably expect to renew. For example, we include annualized monthly maintenance revenue reduced by our historical average maintenance non-renewal rate in backlog.

We compute our backlog as of a specific date, and we update our backlog to reflect changes in our estimates and judgments or subsequent additions, delays, terminations or reductions in our agreements. We also have agreements denominated in foreign currencies, and variation in currency exchange rates can influence our calculation of backlog. We compute backlog using then-existing currency exchange rates and update backlog to reflect changes in these rates.

For these and other reasons, we do not believe that backlog is a meaningful indicator of future revenue to be recognized in any particular period, and there can be no assurance that our backlog at any point in time will translate into revenue in any subsequent period.

We had backlog of $84.3 million as of December 31, 2009 as compared to backlog of $83.6 million as of December 31, 2008. The portion of our backlog as of December 31, 2009 not reasonably expected to be recognized as revenue within the next twelve months is estimated to be $33 million.

Non-GAAP Financial Measures

PROS has provided in this release certain financial information that has not been prepared in accordance with GAAP. This information includes non-GAAP income from operations, net income and diluted earnings per share. PROS uses these non-GAAP financial measures internally in analyzing its financial results and believes they are useful to investors, as a supplement to GAAP measures, in evaluating PROS’ ongoing operational performance. PROS believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results. As noted, the non-GAAP financial measures discussed above are equity-based compensation charges for the quarter and year ended December 31, 2009 of $1.5 million and $5.5 million, respectively, pursuant to GAAP stock-based compensation.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measure as detailed above. A reconciliation of GAAP to the non-GAAP financial measures has been provided in the tables included as part of this press release. PROS use of non-GAAP financial measures may not be consistent with the presentations by similar companies in PROS industry.
