Houston, Texas – August 24, 2007 – PROS Holdings, Inc. (NYSE: PRO), a leader in pricing and revenue optimization software, was recently featured on the front page of the Houston Chronicle’s Business section. The article highlights the Dollar Thrifty Auto Group and the dramatic ROI achieved by implementing PROS pricing and revenue optimization products.

PROS solves the most complex and processing intensive B2B and B2C pricing problems including customers with 100s of simultaneous users and sub-second electronic transactions. PROS provides unique real-time optimized prices for 100 million individual transactions per day. PROS has Blue-chip customers in each of our five verticals; manufacturing, distribution, services, hotel/cruise, airlines.

Excerpts from the recent article:

For a global rental car company that spends $700 million on vehicles each year, the difference between buying almost the right mix vehicles and exactly the right mix can be tens of millions of dollars. So Dollar Thrifty Automotive Group turned to Houston's PROS Holdings and the company's pricing and revenue optimization software to figure out which cars to put where. And, by crunching data, the software does a better job than the Dollar Thrifty's employees can do based on their experience and intuition.

"With human judgment, maybe we got it about 90 percent right," said Stewart Brown, Dollar Thrifty's vice president of revenue management. "This system gets us closer to 100 percent." That 10-percentage-point swing pencils out to about $70 million. PROS software isn't cheap, but it's worth it, Brown said.

For Dollar Thrifty, PROS software analyzes thousands of transactions worth of data to figure out where to put which cars when.

Where PROS is most impressive — and outshines its competition — said Brown, the Dollar Thrifty vice president, is that its expertise extends to the entire business instead of stopping at plugging numbers into the software and pushing a button.

"They crossed over some issues we hadn't even thought of," Brown said. "It actually should improve our customer service because we'll have more of the cars that people want at the right locations."

…Opportunities are growing in the pricing management software business, said John Hagerty, an analyst at AMR Research, which last year estimated the value of the market for all the companies in this business at $348 million in 2007 and growing to $1.1 billion in 2010. "A lot of people haven't discovered it yet," he said.

PROS was recently listed on the New York Stock Exchange. “PROS is a leader in the emerging high-growth pricing and revenue optimization market. Achieving a listing on the NYSE is the result of the hard work and dedication of our 300+ employees who are smart people doing great things to bring high-value Pricing and Revenue Optimization software solutions to our customers,” states Ron Woestemeyer, PROS Executive Vice President and Co-founder.
