Paying employees in stock is a lot of BS when the company has good cash flows. This is meant for companies that have little cash flows (start ups). They almost lost the last vote on compensation at the annual meeting. Next year they will surely lose the right to pay themselves like they are.
As mad as I am about that, the company is not a sell. With time, they will move more into the travel space and be able to make money from the "big data" in the same way Google does from their data and search. That is why Google is working with them. I have no idea what Google is doing with their purchase of ITA but they bought it because they know travel is a big market to get into. I would guess that they see Concur as a good partner to do something in the travel space if they can prove out this open booking. There looks to be a path to scaling this up and I would not bet against it.
