He's Matthew J. Hart, currently president and COO, and he'll replace longtime CEO Stephen Bollenbach early next year. Bollenbach's departure was announced earlier this year. Hart, who joined Bev Hills-based Hilton in 1996 as chief financial officer, will be only the fourth CEO in the company's 90-year history, following Conrad N. Hilton, Barron Hilton and Bollenbach. The long-term growth outlook is quite strong (there's been takeover speculation from time to time), even though first-quarter earnings fell 9 percent and full-year earnings guidance was lowered. Hilton blames it on the cost of renovating some of its properties.
