FINANCIAL RESULTS

Pricing and Revenue Optimization Leader Reports Record Quarterly Revenue

• Record revenues of $16.4 million, an increase of 32% year-over-year

• Non-GAAP income from operations of $3.3 million, an increase of 53% year-over-year

• Non-GAAP net income of $3.0 million or $0.11 per diluted share

Houston, Texas — October 29, 2007 — 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, 2007.

Revenues for the third quarter of 2007 were a record $16.4 million, a 32% increase over the third quarter of 2006. License and implementation revenues were $11.7 million in the quarter, an increase of 41% from $8.3 million in the prior year period.

Bert Winemiller, Chairman and CEO of PROS stated, “We are pleased that we exceeded our target metrics in our first full quarter as a public company. The third quarter of 2007 marked record revenue, strong operating income, and positive operating cash flow. The momentum we are building in the pricing and revenue optimization market increases my confidence and optimism about our growth prospects for the future.”

Non-GAAP operating income was $3.3 million, up 53% year-over-year, and non-GAAP net income was $3.0 million, or $0.11 per share, compared with $2.0 million, or $0.10 per share in the third quarter of 2006. These non-GAAP figures in 2007 exclude $0.4 million in FAS123R stock-based compensation charges, $0.4 million in one-time deferred financing costs and $1.1 million tax benefit due to the reversal of a valuation allowance previously recorded against our deferred tax assets.

Charles Murphy, Executive Vice President and CFO said, “We are pleased to be able to report continued growth for PROS in the third quarter. Our revenue model provides a high level of predictability to our business and adds to our history of profitability and positive operating cash flow. Strong non-GAAP gross margin reached 72.2% in the third quarter, a record for PROS. Strong revenue, combined with lower than expected selling, general and administrative expenses helped us achieve non-GAAP operating margin of 19.9%, above our forecast for the quarter.”

For the quarter ended September 30, 2007 PROS reported income from operations, in accordance with accounting principles generally accepted in the United States of America (“GAAP”), of $2.9 million compared with $2.1 million for the same period in 2006, a 33% increase. Net income was $3.5 million, compared with $2.1 million in the third quarter of 2006, a 65% increase. Net income per diluted share was $0.13 for the quarter compared to net income per diluted share of $0.10 for the same period in 2006.

The attached table represents 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 nine months ended September 30, 2007 and 2006.

Cash and equivalents were $40.0 million for the third quarter, an increase from $4.2 million at the end of second quarter 2007. The increase was primarily due to net operating cash flow of $5.6 million, a $31.2 million increase in net cash provided by financing activities, which include, the proceeds from our initial public offering offset by the retirement of the $20 million credit facility, and cash used in investing activities of $1.0 million.

Our effective GAAP tax rate was (19%) in the third quarter compared to 20% in the prior year. Included in our tax expense for the third quarter of 2007 is a benefit of $1.1 million due to the reversal of a valuation allowance previously recorded against our deferred tax assets. The reversal is the result of our conclusion that it is more likely than not that the associated deferred tax assets will be realized. Without this reversal our effective tax rate would have been 20%. Our effective tax rate historically has been lower than the statutory rate of 34% largely due to the application of general business tax credits, and we expect to continue to benefit from these credits for the foreseeable future. We expect the effective tax rate to be approximately 27% to 28% in 2008.

Financial Outlook

Based on information as of September 30, 2007, PROS is updating guidance for the fourth quarter and full year as follows:
