Concur this week had no comment on a Bloomberg report that the company has discussed a possible sale to Oracle or SAP.

"We do not comment on rumors or speculation," according to a Concur spokesperson. Bloomberg reported that Concur has enlisted an investment bank to pursue the idea, and that Oracle already declined the opportunity. Concur continues to report solid revenue growth but took losses for each of its past three fiscal years. Enterprise software maker SAP, meanwhile, recently announced plans for new integration between its Cloud for Travel system and Amadeus. Its expense system, which competes with Concur's, serves such big customers as BASF, ConocoPhillips, Interpublic, Merck, Nestle, Novartis, PricewaterhouseCoopers, Publicis, Royal Dutch Shell, Sanofi, United Technologies Corp., Walt Disney and World Bank Group, according to BTN's 2013 Corporate Travel 100 report.
