The results of operations of Intercable Automotive are reported within the Engineered Components segment from the date of acquisition.

Any measurement period adjustments were recorded to retained earnings, with a corresponding increase or reduction to net income (loss) attributable to Aptiv. In June 2026, the noncontrolling interest holders exercised their option to sell the remaining 15% of Intercable Automotive at the contractually defined value of approximately $67 million. The transaction closed on June 30, 2026. As a result, Aptiv owned 100% of the equity interest in Intercable Automotive as of June 30, 2026, and no redeemable noncontrolling interest remained.
