St. Petersburg, FL — January 30, 2013—The Jabil (NYSE: JBL) Board of Directors has named William E. Peters to the position of President and William D. Muir, Jr. to Chief Operating Officer, effective March 1, 2013. Both current officers of Jabil have been with the company for more than 20 years.

“I am very excited about these leadership changes and proud that we have developed such a strong internal bench of manufacturing executives. Although we are a global manufacturing services provider, we are truly in the ‘people business’. I believe we have the absolute best team. A team that takes exceptional care of our people, while remaining focused on serving our customers and shareholders,” said Mark Mondello, Jabil’s Chief Operating Officer.

Bill Peters, Executive Vice President, since 2010, joined Jabil in 1990 as a buyer and shortly thereafter was named Purchasing Manager.

Beginning in 2004 Peters rounded out his operational experience while serving three years as Regional President for the Americas. In September 2007, Peters was named Senior Vice President, Human Development. “Bill’s well-rounded experience in business, operations and human development make him particularly well-suited to tackle this new role of unlocking Jabil’s differentiators and cultural advantages to drive on-going business efficiencies,” said Mondello. Prior to joining Jabil, Peters was a financial analyst for Electronic Data Systems and holds a B.A. in Economics from Michigan State University.

Bill Muir, Executive Vice President, since April 2010, joined Jabil in 1992 as a Quality Engineer. Over the next nine years Muir served as Operations Manager for four different

plants in the Americas, honing his operational expertise and utilizing his Spanish fluency to rapidly expand Jabil’s Latin American service offering. Muir complimented his operational experience by working with many of our largest customers during his tenure as Vice President of Global Business Units. In 2004, Muir was promoted to Regional President for Asia and was stationed there for three years. “I know Bill will help us take advantage of the many wonderful opportunities that lie ahead of us as we continue to differentiate our capabilities,” noted Mondello. Muir holds a Bachelor’s degree in Industrial Engineering and an MBA, both from the University of Florida.
