Halliburton Co. President Jeff Miller will add CEO to his title effective June 1, succeeding Dave Lesar, who is continuing as executive chairman. Miller, who already serves on the board, joined Halliburton in 1997 and formerly was COO. He holds a bachelor of science in agriculture and business from McNeese State University in Louisiana and a master’s degree from Texas A&M University. Lesar, who has been chairman and CEO since 2000, plans as executive chairman to focus on the company's strategic direction and be actively engaged with shareholders and customers. Lesar, who joined Halliburton in 1993, entered into an executive employment agreement that provides that he will continue as executive chairman until mandatory retirement on Dec. 31, 2018; it also contains a four-year noncompete agreement. "I have known and worked with Jeff for almost 30 years and have great confidence that he is the best choice to be the next Halliburton CEO," Lesar said.
