Houston, Texas — November 6, 2008 — PROS Holdings, Inc. (NYSE: PRO), a leading provider of pricing and revenue optimization science and software, today announced financial results for the third quarter ended September 30, 2008.

Revenues for the third quarter of 2008 were a record $19.3 million, a 17% increase over the third quarter of 2007.  License and implementation revenues were $13.7 million in the quarter, an increase of 18% from a year ago, and maintenance revenue was $5.6 million, up 17% from the third quarter of 2007.

Bert Winemiller, Chairman and CEO of PROS stated, “We are pleased that we have met the high end of our revenue target and exceeded our earnings per share target in the third quarter of 2008 and believe it was a solid performance given the current challenging economic environment.  These results are validation of PROS proven business model of delivering high-ROI pricing and margin optimization software products to our customers and our high-visibility revenue model. Our third quarter results reaffirm the value of PROS pricing and margin optimization software as a strategic innovation and a risk mitigation initiative when companies face uncertain unpredictable demand and volatile costs.  PROS proven track record, processes, and solutions are the keys to our success and drive our high level of customer satisfaction.”

For the quarter ended September 30, 2008, PROS reported income from operations, in accordance with accounting principles generally accepted in the United States of America (“GAAP”), of $3.4 million compared with $2.9 million for the same period in 2007.  GAAP net income in the quarter was $2.4 million, or $0.09 per diluted share, compared with $3.5 million, or $0.13 per diluted share, in the third quarter of 2007.  Included in our GAAP tax expense for the third quarter of 2007 is a benefit of a $1.1 million reversal of a valuation allowance previously recorded against our deferred tax assets.  In addition to the reversal of valuation allowance, the third quarter of 2007 benefited from the utilization of the Research and Experimentation (“R&E”) tax credit carryforwards and the availability of the R&E tax credits.

The effective GAAP and Non-GAAP tax rate was 35% in the third quarter of 2008 compared to an effective GAAP tax rate of (19%) and Non-GAAP tax rate of 20% in the third quarter of 2007.  In 2007, the Non GAAP tax rate reflects the reversal of the valuation allowance.  The GAAP effective tax rate would have been 20% without the benefit of the reversal of the valuation allowance.

In the third quarter of 2008, Non-GAAP income from operations was $4.4 million compared with $3.3 million for the same period in 2007.   Non-GAAP net income was $3.0 million, or $0.12 per diluted share, compared with Non-GAAP

net income of $3.0 million, or $0.11 per diluted share in the third quarter of 2007.  These Non-GAAP figures in the third quarter of 2008 and 2007 exclude $1.0 million and $0.4 million, respectively, of SFAS 123R stock-based compensation charges.

For the third quarter of 2008, our diluted shares were 26.3 million compared with diluted shares of 26.2 million for the third quarter of 2007.

Charles Murphy, Executive Vice President and CFO stated, “Given the uncertainty of the global economic environment, we are very pleased with our operating results for the quarter.  Continued strong revenues in the quarter, combined with improvements in our gross margins on a year over year basis and lower operating expenses resulted in Non-GAAP operating margins of 23% and earnings per share of $0.12, which was above our guidance.  On October 3, 2008, the research and experimentation tax credit was renewed retroactive to January 1, 2008.  This credit reduces our annual effective tax rate to approximately 29% in 2008 and the cumulative effect on 2008 will be reflected in our fourth quarter GAAP results.  The R&E tax credit has been extended through December 2009.”

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 third quarter and the nine months ended September 30, 2008 and 2007.

Cash and equivalents were $48.1 million at the end of the third quarter of 2008, an increase of $3.7 million from December 31, 2007.  Since the commencement of the Company’s stock repurchase program, the Company has repurchased 286,100 shares for approximately $2.7 million as of September 30, 2008.
