JABIL REPORTS SECOND QUARTER RESULTS

St. Petersburg, FL – March 25, 2008...Jabil Circuit, Inc. (NYSE: JBL), today reported its preliminary, unaudited financial results for its second quarter of fiscal year 2008, ended February 29, 2008. “We are pleased with the results from our second quarter, where our employees pulled together in a challenging operating environment. Thanks to their efforts, we were able to meet our expectations for the quarter and generate $134 million in cash from operations,” said President and CEO Timothy L. Main.

(Definitions used: “GAAP” means generally accepted accounting principles in the United States of America. Jabil defines core operating income as GAAP operating income before amortization of intangibles, stock-based compensation expense and related charges, acquisition-related charges and restructuring and impairment charges. Jabil defines core operating margin as core operating income divided by net revenue. Jabil defines core earnings as GAAP net income before amortization of intangibles, stock-based compensation expense and related charges, acquisition-related charges, restructuring and impairment charges and certain other income/loss, net of tax. Jabil defines core earnings per share as core earnings divided by the weighted average number of outstanding shares determined under GAAP. Jabil reports core operating income, core earnings and core earnings per share to provide investors with an alternative method for assessing operating income, earnings and earnings per share from what it believes are its core manufacturing operations. See the accompanying reconciliation of Jabil’s core operating income to its GAAP operating income and Jabil’s core earnings and core earnings per share to its GAAP net income and GAAP earnings per share and additional information in the supplemental information.)

Second Quarter 2008

Business Update

“We expect revenue in the second half of fiscal 2008 to be consistent with the first half of the year, resulting in a year of modest growth but below our previous expectations. It appears the slowdown in end markets will reduce our growth rate and impede margin expansion for the next quarter or two. However, we continue to win new business and will stay focused on margin expansion, free cash flow and returns on capital,” said Main.

The company expects third fiscal quarter of 2008 net revenue in a range of $3.05 billion to $3.15 billion, with an estimated core operating margin range of 2.3 to 2.6 percent. Jabil said its core earnings per share for its third quarter of fiscal 2008 are anticipated to be in a range of $0.18 to $0.22 per diluted share. GAAP earnings per share are estimated to be $0.09 to $0.13 per diluted share. (Expected GAAP earnings per share for the third quarter of fiscal 2008 are currently estimated to include $0.03 per share for amortization of intangibles and $0.06 per share for stock-based compensation and related charges.)

Jabil said it expects fiscal year 2008 net revenue to range from $12.6 billion to $12.8 billion, with full year core operating income estimated to range from 2.8 percent to 3.1 percent or $355 million to $395 million. The company said its core earnings per share are estimated to be $1.00 to $1.16 per diluted share. GAAP earnings per share are estimated to be $0.46 to $0.62 per diluted share.
