During the third quarter, we increased our global footprint with the addition of new customers and deepened our partnerships with existing customers. For the second year in a row one of our customers named PROS vendor of the year, reflecting our commitment to form partnerships with customers that produce exceptional results. At a time when the power of pricing is receiving increased attention, we believe PROS has never been stronger, and we are confident that our success in 2011 will drive continued momentum heading into 2012.”

For the quarter ended September 30, 2011, income from operations in accordance with GAAP, was $2.6 million, which exceeded the high end of the guidance for the quarter, compared with a loss from operations of $3.8 million in the third quarter of 2010.
