Bridgestone Americas CEO retiring

Corner-office roles will be split between division head and GC

Mark Emkes will retire at the end of this month as chairman, president and CEO of Bridgestone Americas Inc. He has held those jobs since 2004 and has been with the tire maker for more than 33 years.

Bridgestone has named Asahiko "Duke" Nishiyama to succeed Emkes as chairman and named Gary Garfield president and CEO. Nishiyama is currently chairman, president and CEO of Bridgestone Americas Tire Operations, the division that oversees Latin American tire operations and the U.S. and Canadian consumer and commercial tire businesses. Garfield has been vice president and general counsel since 2007.

Emkes, 56, did not say what if anything he plans to do next. The company said splitting Emkes' jobs will “further enhance the company’s corporate governance structure and more clearly differentiate ... responsibilities and accountabilities.”

Bridgestone also said that Eduardo Minardi, president of the company's Latin American Tire division, will take over from Nishiyama as head of BATO and also be COO of Nashville-based Bridgestone Americas.
