Supplemental Information Regarding Non-GAAP Financial Measures: Jabil provides supplemental, non-GAAP financial measures in this release to facilitate evaluation of Jabil’s core operating performance. These non-GAAP measures exclude certain amounts that are included in the most directly comparable U.S. GAAP measures, do not have standard meanings and may vary from the non-GAAP financial measures used by other companies. Management believes these “core” financial measures are useful measures that facilitate evaluation of the past and future performance of Jabil’s ongoing operations on a comparable basis.
