Separation of Electrical Distribution Systems	SEPARATION OF ELECTRICAL DISTRIBUTION SYSTEMS On January 22, 2025, the Company announced its intention to pursue a Separation of its Electrical Distribution Systems business. On April 1, 2026, pursuant to the Separation and Distribution Agreement, the Company transferred to Versigent the assets and liabilities that comprised Versigent’s business and completed the Separation by distributing to Aptiv shareholders on a pro rata basis all of the outstanding ordinary shares of Versigent. Versigent began trading on the NYSE under the symbol “VGNT” on April 1, 2026. In connection with the Separation, the Company received an initial cash distribution of approximately $1.9 billion from Versigent. The Company used the proceeds received from the cash distribution to redeem the 4.650% Senior Notes and settle the Tender Offer, as described in Note 8. Debt. Versigent financed this cash distribution through the issuance of the Versigent Debt, as described in Note 8. Debt, which was transferred to Versigent on April 1, 2026, and is no longer reflected in the Company’s consolidated financial statements beginning April 1, 2026. In connection with the Separation, Aptiv and Versigent entered into various agreements to effect the Separation and to provide a framework for their relationship following the Separation, which included a Separation and Distribution Agreement, Transition Services Agreement, Tax Matters Agreement, Employee Matters Agreement, Intellectual Property Cross License Agreement and Supply Agreements. The transition services primarily involve Aptiv providing certain services to Versigent related to information technology for terms of up to 24 months following the Separation. In addition, the Company expects to recognize the payment of approximately $50 million in bank-related success fees in the second quarter of 2026 coinciding with completion of the Separation. During the three months ended March 31, 2026 and 2025, the Company incurred costs of approximately $57 million and $19 million, respectively, related to the Separation. These costs, which are included in selling, general and administrative expense within the consolidated statements of operations, were primarily related to third-party professional fees associated with planning and executing the Separation. The Company expects to continue to incur additional expenses related to the Separation during 2026. Commencing with the second Quarterly Report on Form 10-Q of 2026, the Company will present Versigent as a discontinued operation throughout the consolidated financial statements and the accompanying notes to the consolidated financial statements.
