Explanation of Responses:

( 1 )On April 1, 2026 (the "Distribution Date"), Aptiv PLC ("Aptiv") completed a distribution of all of the ordinary shares, par value $0.01 per share, of the Issuer ("Issuer Ordinary Shares") to holders of ordinary shares of Aptiv ("Aptiv Ordinary Shares") on a pro rata basis (the "Distribution"). ( 2 )Under the Employee Matters Agreement, dated March 30, 2026, between Aptiv and Issuer, and the Aptiv Long-Term Incentive Plan (the "LTIP"), each restricted stock unit award with respect to Aptiv Ordinary Shares granted by Aptiv under the LTIP prior to the Distribution Date (each, an "Aptiv RSU Award") was equitably adjusted and converted into a restricted stock unit award with respect to Issuer Ordinary Shares (each, an "Issuer RSU Award"), based on (I) the number of Aptiv Ordinary Shares underlying the Aptiv RSU Award immediately prior to the Distribution and (II) a fraction, the numerator of which is (A) the closing price of an Aptiv Ordinary Share on the New York Stock Exchange ("NYSE") on the trading day immediately after the Distribution Date, and (B) the denominator of which is the two-day volume-weighted average price of an Issuer Ordinary Share on the NYSE during the first and second trading days immediately after the Distribution (the "Award Conversion"). ( 3 )Represents Issuer RSU Awards upon the conversion of certain Aptiv RSU Awards held by the Reporting Person as of immediately prior to the Distribution pursuant to the Award Conversion. The Issuer RSU Awards are subject to the terms of the Versigent PLC 2026 Long-Term Incentive Plan and are generally subject to substantially the same terms, vesting conditions and other restrictions as applicable to the related Aptiv RSU Award as of immediately prior to the Distribution. ( 4 )This amount includes Issuer Ordinary Shares received by the Reporting Person in connection with the Distribution.
