Note 17. Segments
We are a global provider of high-technology products to virtually every major on-highway vehicle manufacturer in the world. Our technologies include drive systems (axles, driveshafts and transmissions); electrodynamic technologies (motors, inverters, software and control systems, battery-management systems, and fuel cell plates); sealing solutions (gaskets, seals, cam covers, and oil pan modules); thermal-management technologies (transmission and engine oil cooling, battery and electronics cooling, charge air cooling, and thermal-acoustical protective shielding); and digital solutions (active and passive system controls and descriptive and predictive analytics). Effective January 1, 2025, Dana’s chief operating decision maker (CODM) realigned Dana’s operating segments, reflecting Dana’s commitment to streamlining the business, enhancing our go-to market approach, and serving our customers more efficiently. Our former Power Technologies operating segment has been split, integrating the OEM-facing business into our Light Vehicle Systems operating segment and integrating the aftermarket business into our Commercial Vehicle Systems operating segment. In addition, in June 2025 we entered into a definitive agreement to sell our Off-Highway business to Allison Transmission Holdings, Inc. See Note 2 for additional information. Certain operations that fell outside of the sale perimeter, including certain Dana TM4 operations and our European hydraulics business, have been integrated into our Commercial Vehicle Systems and Light Vehicle Systems operating segments, respectively. We now serve our global light vehicle and medium/heavy vehicle markets through two operating segments – Light Vehicle Systems (Light Vehicle) and Commercial Vehicle Systems (Commercial Vehicle). These operating segments have global responsibility and accountability for business commercial activities and financial performance. Amounts presented for prior periods have been recast to align with Dana’s current two operating segments. Dana’s Chief Executive Officer is its CODM.
Dana evaluates the performance of its operating segments based on external sales and segment EBITDA. Segment EBITDA is a primary driver of cash flows from operations and a measure of our ability to maintain and continue to invest in our operations and provide shareholder returns. Our segments are charged for corporate and other shared administrative costs. Certain corporate and other administrative costs that were historically charged to our Off-Highway business, that are not permitted to be reflected as part of discontinued operations, have been recast and are included within the "corporate expense and other items, net" line of the reconciliation of segment EBITDA to earnings (loss) from continuing operations before income taxes. Segment EBITDA may not be comparable to similarly titled measures reported by other companies.
