BATTLE CREEK, MICH. — David Mackay, president, chief executive officer and director of Kellogg Co., has announced his intentions to retire on Jan. 1. John A. Bryant, currently chief operating officer and board member, will succeed Mr. Mackay.

“I have had the distinct privilege of working for this great company over the past 20 years and serving as its c.e.o. for the past four years,” Mr. Mackay said. “This past summer, I became eligible to retire and made a commitment to spend more time with my family. I am pleased to pass the baton to John, whose management capabilities and wealth of experience have prepared him well to drive our business agenda for 2011 and beyond.”

Mr. Bryant has been with the company since 1998 in various roles, including leading the North America and International business units and being chief financial officer.

“John has played a central role in our strategic and operational plans over the past decade,” said Jim Jenness, chairman of the board of directors. “His leadership style embodies the Kellogg spirit and values. The board and I are confident that his depth of knowledge and understanding of our business, our customers and our organization make him the right choice to lead our company.”
