R. Brad Martin has been appointed nonexecutive chairman of Chesapeake Energy Corp. Martin is chairman of RBM Ventures and retired CEO of Saks Inc. He was appointed to Chesapeake's board in June 2012. He also serves on the board of FedEx Corp. and First Horizon National Corp. He holds a degree from the University of Memphis and a master's degree from Vanderbilt University. He succeeds Archie W. Dunham, who came aboard in 2012 and is to remain a director and chairman emeritus (see Daily GPI, June 22, 2012). "Chesapeake will benefit from Brad's unique insight and extensive business experience as he serves in his new role as chairman of the board," said Dunham, 76, who came out of retirement after leading ConocoPhillips and predecessor companies for 40 years. "Chesapeake has a bright future, given its exceptional portfolio, operations, and management team," Dunham said. "With all the meaningful changes we have made at Chesapeake over the past three years, significant opportunities lie ahead." Martin said he felt "privileged to succeed Archie in this role and look forward to working closely" with CEODoug Lawler and the board.
