APTIV SUPPLEMENTAL HISTORICAL FINANCIAL RESULTS

APTIV SUPPLEMENTAL HISTORICAL FINANCIAL RESULTS

Overview Basis of Presentation The historical amounts within this presentation are presented on a pro forma Aptiv continuing operations basis, which gives effect to the spin-off of Delphi Technologies PLC ( Delphi Technologies ) and reflects Delphi Technologies historical financial results as discontinued operations for all periods presented. Amounts within this presentation were derived from the Company s unaudited consolidated pro forma financial information filed on Form 8-K with the Securities and Exchange Commission ( SEC ) on December 7, 2017, and should be read together with that filing, as well as with Aptiv s Form 10-K for the year ended December 31, 2016 and Form 10-Q for the period ended September 30, 2017. Use of Non-GAAP Financial Information This presentation contains information about Aptiv s financial results which are not presented in accordance with GAAP. Specifically, Pro Forma Adjusted Operating Income, Pro Forma Adjusted Operating Income Margin, Pro Forma Adjusted Net Income and Pro Forma Adjusted Net Income per Share are non-gaap financial measures. Pro Forma Adjusted Operating Income represents net income before interest expense, other income (expense), net, income tax expense, equity income (loss), net of tax, income (loss) from discontinued operations, net of tax, restructuring, other acquisition and portfolio project costs, asset impairments and gains (losses) on business divestitures, and presented within this presentation on a pro forma basis to give effect to the spin-off of Delphi Technologies. Pro Forma Adjusted Operating Income margin is defined as Pro Forma Adjusted Operating Income as a percentage of Net sales. Pro Forma Adjusted Net Income from continuing operations represents net income attributable to Aptiv before restructuring and other special items, including the tax impact thereon, within this presentation on a pro forma basis to give effect to the spin-off of Delphi Technologies. Pro Forma Adjusted Net Income Per Share attributable to Aptiv represents Adjusted Net Income divided by the weighted average number of diluted shares outstanding for the period. Management believes that these non-gaap measures are useful to investors in assessing the Company s historical performance on a basis that excludes the results of operations of Delphi Technologies, and better explain the Company's results of operations in a manner that allows for a more complete understanding of the underlying trends in the Company's business. Such non-gaap financial measures are reconciled to the most directly comparable GAAP financial measures within this presentation. Non-GAAP measures should not be considered in isolation or as a substitute for our reported results prepared in accordance with GAAP and, as calculated, may not be comparable to other similarly titled measures of other companies. 2
