Jabil Posts First Quarter Results

St. Petersburg, FL – December 15, 2016. Today Jabil Circuit, Inc. (NYSE: JBL), reported preliminary, unaudited financial results for its first quarter of fiscal year 2017, including first quarter net revenue of $5.1 billion.

For the first quarter of fiscal year 2017, U.S. GAAP (as defined below) operating income was $165.6 million and U.S. GAAP net diluted earnings per share was $0.47. Core operating income ((Non-U.S. GAAP) as defined below) was $209.5 million and core diluted earnings per share ((Non-U.S. GAAP) as defined below) was $0.69.

“I’m really pleased with our strong first quarter results,” said CEO Mark Mondello. “In particular, we saw strength in our healthcare, packaging and consumer lifestyles businesses within our DMS segment, combined with yet another solid quarter of execution from our EMS segment, allowing us to deliver excellent results,” he added.

Fiscal Year 2017 Second Quarter Guidance:

“Looking ahead, we’ll remain focused on our multi-year financial objectives and longer-term enterprise goals, while following through on our commitment to return capital to shareholders, as previously communicated under our two-year capital allocation framework,” added Mondello.

(U.S. GAAP net diluted earnings per share for the second quarter of fiscal year 2017 are currently estimated to include $0.05 per share for amortization of intangibles, $0.08 per share for stock-based compensation expense and related charges and $0.26 to $0.40 per share for restructuring and related charges.)

(Definitions used: “U.S. GAAP” means U.S. generally accepted accounting principles. Jabil defines core operating income as U.S. GAAP operating income before amortization of intangibles, stock-based compensation expense and related charges, restructuring and related charges, distressed customer charges, acquisition costs and certain purchase accounting adjustments, loss on disposal of subsidiaries, settlement of receivables and related charges, impairment of notes receivable and related charges and goodwill impairment charges. Jabil defines core earnings as U.S. GAAP net income before amortization of intangibles, stock-based compensation expense and related charges, restructuring and related charges, distressed customer charges, acquisition costs and certain purchase accounting adjustments, loss on disposal of subsidiaries, settlement of receivables and related charges, impairment of notes receivable and related charges, goodwill impairment charges, income (loss) from discontinued operations, gain (loss) on sale of discontinued operations and certain other expenses, net of tax and certain deferred tax valuation allowance charges. Jabil defines core diluted earnings per share as core earnings divided by the weighted average number of outstanding diluted shares as determined under U.S. GAAP. Jabil calculates its quarterly core return on invested capital by annualizing its after-tax core operating income for its most recently ended quarter and dividing that by a two quarter average of its net invested capital

base. Jabil calculates its annual core return on invested capital by taking its after-tax core operating income for its most recently ended fiscal year and dividing that by a two year average of its net invested capital base. Jabil reports core operating income, core earnings, core diluted and basic earnings per share and core return on invested capital to provide investors an additional method for assessing operating income, earnings, diluted earnings per share and return on invested capital from what it believes are its core manufacturing operations. See the accompanying reconciliation of Jabil’s core operating income to its U.S. GAAP operating income, its calculation of core earnings and core diluted earnings per share to its U.S. GAAP net income and U.S. GAAP earnings per share, its calculation of core return on invested capital and additional information in the supplemental information.)

FORWARD LOOKING STATEMENTS: This news release contains forward-looking statements, including those regarding our anticipated financial results for our first quarter of fiscal year 2017; and our positioning for future financial performance in our second quarter of fiscal year 2017 (including, net revenue, segment net revenue, U.S. GAAP operating income, U.S. GAAP net diluted earnings per share, core operating income, and core diluted earnings per share results and the components thereof, in each case for our second quarter of fiscal year 2017); and statements that relate the Company’s capital allocation framework, including our share repurchase program thereunder, the amount of shares to be repurchased and the timing of such repurchase). The statements in this presentation are based on current expectations, forecasts and assumptions involving risks and uncertainties that could cause actual outcomes and results to differ materially from our current expectations. Such factors include, but are not limited to: our determination as we finalize our financial results for our first quarter of fiscal year 2017 that our financial results and conditions differ from our current preliminary unaudited numbers set forth herein; unexpected, adverse seasonal impacts on demand; performance in the markets in which we operate; changes in macroeconomic conditions; the occurrence of, success and expected financial results from, product ramps; our ability to maintain and improve costs, quality and delivery for our customers; whether our restructuring activities and the realignment of our capacity will adversely affect our cost structure, ability to service customers and labor relations; changes in technology; competition; anticipated growth for us and our industry that may not occur; managing rapid growth; managing rapid declines in customer demand and other related customer challenges that may occur; our ability to successfully consummate acquisitions and divestitures; managing the integration of businesses we acquire; risks associated with international sales and operations; retaining key personnel; and our dependence on a limited number of large customers. Additional factors that could cause such differences can be found in our Annual Report on Form 10-K for the fiscal year ended August 31, 2016, subsequent Reports on Form 8-K and our other securities filings. We assume no obligation to update these forward-looking statements.

Supplemental Information: The financial results disclosed in this release include certain measures calculated and presented in accordance with U.S. GAAP. In addition to the U.S. GAAP financial measures, Jabil provides supplemental, non-U.S. GAAP financial measures to facilitate evaluation of Jabil’s core operating performance. The non-U.S. GAAP financial measures disclosed in this release exclude certain amounts that are included in the most directly comparable U.S. GAAP measures. The non-U.S. GAAP or core financial measures disclosed in this release do not have standard meanings and may vary from the non-U.S. GAAP financial measures used by other companies. Management believes core financial measures (which exclude the effects of the amortization of intangibles, stock-based compensation expense and related charges, restructuring and related charges, distressed customer charges, acquisition costs and certain purchase accounting adjustments, loss on disposal of subsidiaries, settlement of receivables and related charges, impairment of notes receivable and related charges, goodwill impairment charges, income (loss) from discontinued operations, gain (loss) on sale of discontinued operations and certain other expenses, net of tax and certain deferred tax valuation allowance charges) are a useful measure that facilitates evaluating the past and future performance of Jabil’s ongoing operations on a comparable basis. The Company determines the tax effect of the items excluded from core earnings and core basic and diluted earnings per share based upon evaluation of the statutory tax treatment and the applicable tax rate of the jurisdiction in which the pre-tax items were incurred, and for which realization of the resulting tax benefit, if any, is expected. In certain jurisdictions where the Company does not expect to realize a tax benefit (due to a history of operating losses or other factors resulting in a valuation allowance related to deferred tax assets), a 0% tax rate is applied.

Jabil reports core operating income, core return on invested capital, core earnings and core diluted and basic earnings per share to provide investors an additional method for assessing operating income, return on invested capital, earnings and earnings per share from what it believes are its core manufacturing operations. Among other uses, management uses non-U.S. GAAP financial measures to make operating decisions, assess business performance and as a factor in determining certain employee performance when determining incentive compensation. Included in this release are Condensed Consolidated Statements of Operations as well as a reconciliation of the disclosed core financial measures to the most directly comparable U.S. GAAP financial measures.

CALCULATION OF RETURN ON INVESTED CAPITAL

AND CORE RETURN ON INVESTED CAPITAL

The Company calculates: (1) its “Return on Invested Capital” by annualizing its “after-tax U.S. GAAP operating income” for its most recently-ended quarter and dividing that by the average of its “net invested capital asset base” and (2) its “Core Return on Invested Capital” by annualizing its “after-tax non-U.S. GAAP core operating income” for its most recently-ended quarter and dividing that by the “average net invested capital asset base.”

The Company calculates: (1) its “after-tax U.S. GAAP operating income” by subtracting a certain tax effect (the calculation of which is explained below) from its U.S. GAAP operating income and (2) its “after-tax non-U.S. GAAP core operating income” as its non-U.S. GAAP core operating income less a certain tax effect (the calculation of which is explained below). See elsewhere in this earnings release for a reconciliation of the Company’s non-U.S. GAAP core operating income to its U.S. GAAP operating income.

The Company calculates its “average net invested capital asset base” as the sum of the averages (the calculations of which are explained below) of its stockholders’ equity, current and non-current portions of its notes payable, long-term debt and capital lease obligations less the average (the calculation of which is explained below) of its cash and cash equivalents.

The following table reconciles (1) “Return on Invested Capital,” as calculated using “after-tax U.S. GAAP operating income” to (2) “Core Return on Invested Capital,” as calculated using “after-tax non-U.S. GAAP core operating income”:
