Houston, Texas — February 12, 2009 — PROS Holdings, Inc. (NYSE: PRO), a leading provider of pricing and revenue optimization science and software, today announced financial results for the fourth quarter and year ended December 31, 2008.

Revenues for the fourth quarter of 2008 were a record $19.8 million, an 11% increase over the fourth quarter of 2007, in line with the company’s guided range.  License and implementation revenues were $14.0 million in the quarter, an increase of 12% from a year ago, and maintenance revenue was $5.7 million, up 10% from the fourth quarter of 2007.  For the year ended December 31, 2008, revenue was $75.6 million, with 71% from license and implementation revenue and 29% from maintenance revenue.

Bert Winemiller, Chairman and CEO of PROS stated, “We are pleased with our financial performance in the fourth quarter of 2008. For the full year we are reporting results in line with or above expectations, with the strongest revenue, cash flow, and profit in our history. We believe this was a solid performance given the challenging economic environment in 2008. These results are validation of PROS’ proven business model of delivering high-ROI pricing and margin optimization software products to our customers and our revenue visibility based on our percentage of completion revenue recognition. Companies implement PROS pricing and margin optimization software as a strategic innovation and a risk mitigation initiative, particularly as these companies face unpredictable demand and volatile costs. PROS’ proven track record, proven processes, and proven solutions are the keys to our long-term success and drive our high level of customer satisfaction.”

For the quarter ended December 31, 2008 and 2007, PROS reported income from operations, in accordance with generally accepted accounting principles (“GAAP”), of $3.8 million for each of the periods.  GAAP net income in the quarter was $3.6 million, or $0.14 per diluted share, above expectations, compared with $3.5 million, or $0.13 per diluted share, in the fourth quarter of 2007.

For the quarter ended December 31, 2008, Non-GAAP income from operations was $4.9 million compared with $4.4 million for the same period in 2007.   Non-GAAP net income was $4.6 million, or $0.17 per diluted share, above expectations, compared with Non-GAAP net income of $4.0 million, or $0.15 per diluted share, in the fourth quarter of 2007.  These Non-GAAP results in the fourth quarter of 2008 and 2007 exclude $1.1 million and $0.7 million, respectively, of SFAS 123R stock-based compensation charges.

For the year ended December 31, 2008, income from operations, in accordance with GAAP was $13.9 million compared with $11.0 million for the year ended December 31, 2007.  GAAP net income for the year was $10.8 million, or $0.40 per diluted share, compared with $10.5 million, or $0.45 per diluted share, in 2007.   Cash flow from operations was $13.8 million for the year ended December 31, 2008, an increase of 38% from cash flow from operation of $10.0 million for the year ended December 31, 2007.

For the year ended December 31, 2008, Non-GAAP income from operations was $18.0 million compared with $12.6 million for the year ended December 31, 2007.  Non-GAAP net income for the year was $13.6 million, or $0.51 per diluted share, compared with $11.0 million, or $0.46 per diluted share, in 2007.  These Non-GAAP results for the year ended December 31, 2008 and 2007 exclude $4.0 million and $1.6 million, respectively, of SFAS 123R stock-based compensation charges.

On October 3, 2008, Congress passed the extension of the Research & Experimentation (“R&E”) tax credit.  The R&E tax credit is retroactive to January 1, 2008 and extends the credit until December 31, 2009.  As a result of the retroactive reinstatement of the R&E credit; we recorded the full benefit of the R&E credit in the fourth quarter of 2008 resulting in a fourth quarter effective tax rate of 9.0%.

The effective GAAP and Non-GAAP tax rate was approximately 9.0% and 28.5% for the three months and year ended December 31, 2008, respectively, compared to a GAAP and Non-GAAP tax rate of 19.7%  for the three months ended December 31, 2007 and GAAP and Non-GAAP effective tax rate 10.6% and 20.3%, respectively, for the year ended December 31, 2007.

Charles Murphy, Executive Vice President and CFO stated, “Given the continuing uncertainty of the global economic environment, we are very pleased with our operating results for the quarter and the year.  Our fourth quarter 2008 Non- GAAP operating income was $4.9 million and earnings per share was $0.17.   We are particularly pleased with our full year Non-GAAP operating margins of 23.8%.  The strength of our balance sheet positions us well going into 2009 with $52.0 million in cash, $41.7 million in working capital and no debt.  2008 was our 10th consecutive year of profitability and positive cash flow generation.”

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 fourth quarter and year ended December 31, 2008 and 2007.

Cash and cash equivalents were $52.0 million at the end of the December 31, 2008, an increase of $7.6 million from December 31, 2007.

For the three months ended December 31, 2008, the Company repurchased 284,445 shares for approximately $2.3 million.  Since the commencement of the Company’s stock repurchase program, the Company has repurchased 570,545 shares for approximately $5.0 million as of December 31, 2008.  At December 31, 2008, approximately $10.0 million remained available for the purchase of stock under this plan.

Financial Outlook

Based on information as of today, PROS is providing the following outlook for the first quarter of 2009:

First Quarter of Fiscal Year 2009:

·The Company expects total revenue in the range of $17.5 million to $18.0 million.

·The Company is projecting GAAP income from operations of $1.7 million to $2.3 million and GAAP diluted earnings per share of $0.05 to $0.07.

·The Company is projecting Non-GAAP income from operations of $2.8 million to $3.4 million and Non-GAAP diluted earnings per share of $0.08 to $0.10.  Non-GAAP income from operations for the first quarter excludes estimated SFAS 123(R) stock-based compensation charges of approximately $1.1

1

million.  Earnings per share are based on an estimated weighted average of 26.5 million diluted shares outstanding.

PROS remains positive about the Company’s long-term opportunities and believes 2008 was a good year.  However, as the Company enters 2009 with the global economy in recession, forecasting for the longer-term is considerably more challenging.  As such, PROS will not be providing full-year guidance at this time.
