UPS’s Davis Nears Typical CEO Tenure as Kuehn Seen Next - Bloomberg Since founder Jim Casey left United Parcel Service Inc. (UPS) after more than five decades in charge, the company’s chief executive officers have served for an average of 5 1/2 years. Scott Davis reaches that milestone in June. That means a leadership change is probably approaching at the world’s largest package-delivery operator, according to Kevin Sterling of BB&T Capital Markets and other analysts. A new CEO almost certainly will come from within, as have all the previous chiefs, Sterling said. Transitions since Casey’s 1962 exit have earned UPS a reputation for stability in a situation yet to be faced by FedEx Corp. (FDX), which Fred Smith has led since starting the carrier in 1971. UPS promoted Davis, 61, from chief financial officer and current CFO Kurt Kuehn is the likeliest to succeed him, said Sterling and David Campbell of Thompson Davis & Co.
