Business Combination, Asset Acquisition, Transaction between Entities under Common Control, and Joint Venture Formation [Abstract]
ACQUISITIONS AND DISPOSITIONS	ACQUISITIONS AND DISPOSITIONS Acquisitions In accordance with Accounting Standards Codification (“ASC”) Topic 805, “Business Combinations,” acquisitions are recorded using the acquisition method of accounting. The Company recognizes and measures the acquisition date fair value of the identifiable assets acquired, liabilities assumed and any non-controlling interest using a range of methodologies as indicated by generally accepted valuation practices. Various valuation techniques are used to determine the fair value of intangible assets, with the primary techniques being forms of the income approach, specifically the relief-from-royalty and multi-period excess earnings valuation methods. Under these valuation approaches, the Company is required to make estimates and assumptions from a market participant perspective and may include revenue growth rates, estimated earnings, royalty rates, obsolescence factors, contributory asset charges, customer attrition and discount rates. Due to the insignificant size of the Company’s 2023 and 2022 acquisitions, both individually and in the aggregate, relative to the Company, supplemental pro forma financial information for the current and prior reporting periods is not provided. Hubei Surpass Sun Electric Charging Business On March 1, 2023, the Company completed its acquisition of 100% of the electric vehicle solution, smart grid and smart energy businesses (“SSE”) of Hubei Surpass Sun Electric, pursuant to an Equity Transfer Agreement. The acquisition was expected to complement the Company’s existing European and North American charging footprint by adding a presence in China. The total consideration was ¥288 million ($42 million), including ¥268 million ($39 million) of base purchase price and ¥19 million ($3 million) of estimated earn-out payments. The Company paid ¥217 million ($31 million) of base purchase price during the year ended December 31, 2023 and ¥25 million ($4 million) during the year ended December 31, 2024. During the year ended December 31, 2025, the Company recorded a post-closing adjustment of ¥6 million ($1 million) following the review of final closing payment details. The remaining ¥20 million ($3 million) of base purchase price was recorded in Other current liabilities in the Company’s Condensed Consolidated Balance Sheet as of December 31, 2025. In January 2026, the negotiations of the remaining ¥20 million ($3 million) of base purchase price were completed, and the Company made the final payment. In accordance with ASC Topic 230, the payment made in 2026 was classified as financing activities in the Company’s Condensed Consolidated Statement of Cash Flows, as it occurred more than three months after the acquisition closing date. As described further below, in February 2025, the Company made the decision to exit its charging business within the reportable segment formerly called Battery & Charging Systems, which included SSE. In the first quarter of 2026, as a result of the aforementioned disposition, this reportable segment was renamed Battery Energy Systems. The name change reflects the segment’s revised focus after the divestiture. The change did not impact the composition of the segment or require recasting of prior period segment results. Prior periods continue to be presented as previously reported. Drivetek AG On December 1, 2022, the Company completed its acquisition of 100% of Drivetek AG (“Drivetek”), an engineering and product development company located in Switzerland. This acquisition strengthened the Company’s power electronics capabilities in auxiliary inverters, which has helped to accelerate the growth of the Company’s High Voltage eFan business. The total consideration was ₣37 million ($39 million), including ₣27 million ($29 million) of base purchase price and ₣10 million ($10 million) of estimated earn-out payments. The Company paid ₣27 million ($29 million) of base purchase price at closing. The Company’s obligation to remit up to ₣10 million ($10 million) of earn-out payments, over the three years following closing, is contingent upon achievement of estimated future sales targets associated with newly awarded business and future turnover rate targets. During the year ended December 31, 2025, the Company paid ₣2 million ($2 million) of earn-out-related amounts. During the three months ended March 31, 2026, the Company recorded a post-closing adjustment of ₣2 million ($2 million) reducing the remaining obligation to ₣1 million ($1 million) following the review of final closing payment details. In accordance with ASC Topic 805, the change in estimate was recorded in Other operating (income) expense, net in the Company’s Condensed Consolidated Statements of Operations. The remaining balance was included in Other current liabilities in the Company’s Condensed Consolidated Balance Sheet and is payable before June 30, 2026. Dispositions Exit of Charging Business In February 2025, the Company decided to exit its charging business within the Battery Energy Systems reportable segment. This decision was made following the Company’s continuing evaluation of its product portfolio and future investments. The majority of the charging business related to the SSE business, which was marketed for sale and met the criteria to be reported as held-for-sale as of March 31, 2025. During the three months ended March 31, 2025, the Company recorded a charge of $19 million related to the estimated loss on the sale of the SSE business. The Company’s exit of its charging business did not meet the criteria for presentation as a discontinued operation. During the three months ended March 31, 2025, the Company recorded charges of $26 million related to the exit of its charging business within the Battery Energy Systems reportable segment. These charges include the previously mentioned $19 million estimated loss on the sale of the SSE business, which was recorded in Other operating expense, net, and the write off of $7 million of inventory, which was recorded in Cost of sales in the Condensed Consolidated Statements of Operations. In addition, the Company recorded charges totaling $39 million during the three months ended March 31, 2025, which included impairments of intangible assets, goodwill and fixed assets of $22 million, $13 million and $4 million, respectively. Refer to Note 11, “Goodwill and Other Intangibles,” to the Condensed Consolidated Financial Statements for more information. PHINIA, Inc. On July 3, 2023, BorgWarner completed the spin-off (“Spin-Off”) of its Fuel Systems and Aftermarket segments in a transaction intended to qualify as tax free to the Company’s stockholders for U.S. federal income tax purposes, which was accomplished by the distribution of 100% of the outstanding common stock of PHINIA, Inc. (“PHINIA”) to holders of record of common stock of the Company on a pro-rata basis. In connection with the Spin-Off, the Company entered into several agreements with PHINIA on or prior to the Distribution Date that, among other things, provide a framework for the Company’s relationship with PHINIA after the Spin-Off, including a separation and distribution agreement, an employee matters agreement, a tax matters agreement, an intellectual property cross-license agreement and a transition services agreement through which the Company and PHINIA continued to provide certain services to each other following the Spin-Off. In December 2024, the Company and PHINIA executed an amendment to the original transition services agreement to extend certain engineering services until September 30, 2025. The transition services agreement expired and all related services ended on September 30, 2025. On October 15, 2025, the Company entered into a settlement agreement with PHINIA, and in connection with the settlement agreement, the Company and PHINIA also entered into an amended and restated tax matters agreement that, among other things, limits the Company’s responsibility to certain defined tax obligations.
