Rob Walton relinquished the position of chairman of the board of directors of Wal-Mart Stores, Inc., to his son-in-law, Greg Penner, at the company annual meeting on June 5.
The move to elevate Penner to the new role didn’t come as huge shock since the stage had been set for the move at Walmart’s annual meeting last year when Walton, 70, announced Penner had been named the board’s vice chairman. Walton has served as chairman of the board since 1992 the same year that his father and company founder Sam Walton died. He will continue to serve on the board.
