NOTE 24. REPORTABLE SEGMENTS
Reportable segments under GAAP are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the Chief Operating Decision Maker (CODM), or decision-making group, in deciding how to allocate resources and in assessing performance. Our CODM is the Chief Executive Officer.
Our reportable segments consist of Engine, Components, Distribution, Power Systems and Accelera. This reporting structure is organized according to the products and markets each segment serves. The Engine segment produces engines (15 liters and smaller) and associated parts for sale to customers in on-highway and various off-highway markets. Our engines are used in trucks of all sizes, buses and recreational vehicles, as well as in various industrial applications, including construction, agriculture, power generation systems and other off-highway applications. The Components segment sells axles, drivelines, brakes and suspension systems for commercial diesel and natural gas applications, aftertreatment systems, turbochargers, fuel systems, valvetrain technologies, automated transmissions and electronics. The Distribution segment includes wholly-owned and partially-owned distributorships engaged in wholesaling engines, generator sets and service parts, as well as performing service and repair activities on our products, maintaining relationships with various OEMs throughout the world and providing selected sales and aftermarket support for our Accelera business. The Power Systems segment is an integrated power provider, which designs, manufactures and sells standby and prime power generators, engines (16 liters and larger) for standby and prime power generator sets and industrial applications (including mining, oil and gas, marine, rail and defense), alternators and other power components. The Accelera segment designs, manufactures, sells and supports electrified power systems with innovative components and subsystems, including battery and electric powertrain technologies. The Accelera segment is currently in the early stages of commercializing these technologies with efforts primarily focused on the development of electrified power systems and related components and subsystems. We continue to serve all our markets as they adopt electrification, meeting the needs of our OEM partners and end customers.
Our CODM uses segment EBITDA as the basis to evaluate the performance of each of our reportable segments. EBITDA provides our CODM with a full picture of the profitability of a segment to drive decisions and resource allocation. EBITDA is used as the key profitability measure when we set our annual operating plan, is the metric with which our CODM assesses results and is a key component of our annual variable compensation plans. Segment amounts exclude certain expenses not specifically identifiable to segments.
The accounting policies of our reportable segments are the same as those applied in our Consolidated Financial Statements. We prepared the financial results of our reportable segments on a basis that is consistent with the manner in which we internally disaggregate financial information to assist in making internal operating decisions. We allocate certain common costs and expenses, primarily corporate functions, among segments differently than we would for stand-alone financial information prepared in accordance with GAAP. These include certain costs and expenses of shared services, such as IT, human resources, legal, finance and supply chain management. We do not allocate gains or losses of corporate-owned life insurance and the gain and certain costs related to the divestiture of Atmus. EBITDA may not be consistent with measures used by other companies.

About Segments Disclosures

Segment disclosures break a company into its reportable operating units, revealing revenue, profit, and asset allocation that consolidated financial statements obscure. Under ASC 280, segments must match how the chief operating decision maker views the business, providing a window into internal management structure and resource allocation priorities.

Key signals: compare segment margins to identify which units drive profitability and which destroy value. Watch for changes in the number of reportable segments — segment aggregation or disaggregation often coincides with strategic shifts or attempts to obscure declining performance. Intersegment elimination patterns reveal internal pricing practices. The reconciliation between segment totals and consolidated figures exposes corporate overhead allocation and unallocated items. Geographic revenue concentration highlights regulatory and currency exposure. Compare segment-level capital expenditure against segment revenue to assess where management is investing for future growth versus harvesting existing assets.
