Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On January 24, 2013, the Board appointed: William E. Peters, currently the Company’s Executive Vice President, Human Development, Human Resources, to become the Company’s President and William D. Muir, Jr., currently the Company’s Executive Vice President, Chief Executive Officer, Manufacturing Services, to become the Company’s Chief Operating Officer. Both appointments will be effective March 1, 2013.

Mr. Peters (age 49), Executive Vice President, Human Development, Human Resources since April 2010, joined Jabil in 1990 as a buyer and shortly thereafter was named Purchasing Manager. In 1993 Mr. Peters was named Operations Manager for Jabil’s Michigan facility and was promoted to Vice President, Operations in January 1999. Mr. Peters was named Senior Vice President, Operations in October 2000. He was promoted to Senior Vice President, Regional President — Americas in September 2004. In September 2007, Mr. Peters was named Senior Vice President, Human Development. Prior to joining Jabil, Mr. Peters was a financial analyst for Electronic Data Systems. He holds a B.A. in Economics from Michigan State University.

Mr. Muir (age 44), Executive Vice President, Chief Executive Officer, Manufacturing Services Group since April 2010, joined Jabil in 1992 as a Quality Engineer. Mr. Muir has served in management positions including Senior Director of Operations for Florida, Michigan, Guadalajara, and Chihuahua. Mr. Muir was promoted to Vice President, Operations-Americas in February 2001, was named Vice President, Global Business Units in November 2002 and Senior Vice President, Regional President — Asia in September 2004. Mr. Muir recently served as Executive Vice President, Chief Executive Officer, EMS Division from September 2007 to April 2010. He holds a Bachelor’s degree in Industrial Engineering and an MBA, both from the University of Florida.

Also on January 24, 2013, the Board’s Compensation Committee determined the fiscal year 2013 cash compensation for Mr. Peters and Mr. Muir, as well as additional long-term grants for Mr. Peters. Mr. Muir will receive an annual base salary of $620,000. He will also be eligible for an additional annual cash incentive for fiscal year 2013 with a target amount of 20% of his salary. The actual amount will be determined by the Compensation Committee, after the end of fiscal year 2013, based on: (1) various levels of the Company’s “core operating income” and “core operating profit margin” and (2) “core return on invested capital.” These salary and annual cash incentive changes are effective September 1, 2012.

Mr. Peters will receive an annual base salary of $620,000. He will also be eligible for an additional annual cash incentive for fiscal year 2013 with a target amount of 30% of his salary. The actual amount will be determined by the Compensation Committee, after the end of fiscal year 2013, based on: (1) various levels of the Company’s “core operating income” and “core operating profit margin” and (2) the Company’s “core return on invested capital.” These salary and annual cash incentive changes are effective September 1, 2012. In addition, Mr. Peters received an additional 10,010 time-based restricted stock units that will vest at the rate of 30% on October 16, 2013, 30% on October 16, 2014, and 40% on October 16, 2015. Mr. Peters also received an additional 20,020 performance-based restricted stock units that will vest, if at all, based on the Company’s cumulative, “adjusted core earnings per share” during the performance period beginning September 1, 2012 and ending on August 31, 2017 (the measurement, and potential vesting, dates will be August 31, 2015, August 31, 2016 and August 31, 2017). Finally, Mr. Peters received an additional $220,620 long-term cash-based award that will vest, if at all, based on the Company’s cumulative, “adjusted core earnings per share” during the performance period beginning September 1, 2012 and ending on August 31, 2015.

A result of these January 24, 2013 decisions of the Board’s Compensation Committee, when combined with its decisions earlier in fiscal year 2013, is that Mr. Peters and Mr. Muir will have the same fiscal year 2013 compensation (although because the grant dates for the equity awards differ, the value of these awards will also likely differ): (1) $620,000 annual base salary; (2) annual cash incentives with a target amount of 120% of salary (the actual amount to be determined as described in the above paragraph); (3) $783, 960 long-term cash-based awards (the actual amount to be determined as described in the above paragraph); (4) 71,140 performance-based restricted stock units (the actual amount to be determined as described in the above paragraph); and (5) 35,570 time-based restricted stock units (scheduled to vest as described in the above paragraph).

For purposes of this Current Report on Form 8-K, the applicable defined terms have the meanings specified below:
