As reported on CNBC, looks like UPS will buy TNT Express after all. My guess is this is all about taking on DHL in Europe however I do not know for sure. I have never been a big fan of logistics companies purchasing others unless there is underlying technology you need.
My guess is UPS does not need any technology TNT has. It is dangerous to buy just for a "customer list". Acquisitions are generally not a "10X idea". They usually occur when management is out of ideas.
