Nature of Operations	Note 1 — Nature of Operations The Company operates in two reportable segments: Manufacturing and Leasing & Fleet Management. The segments support the Company's integrated business model. The Manufacturing segment, which currently operates from facilities in the U.S., Mexico, Poland and Romania, produces double-stack intermodal railcars, tank cars, freight railcars, and automotive railcar products. The Manufacturing segment also performs wheel and axle servicing, railcar maintenance services and produces a variety of component parts for the rail industry. The Leasing & Fleet Management segment owns approximately 17,000 railcars as of August 31, 2025 and provides management services for railroads, shippers, carriers, institutional investors and other leasing and transportation companies in North America. Through unconsolidated affiliates the Company produces rail and industrial components and has an ownership stake in a railcar manufacturer in Brazil. Effective September 1, 2024, the Company combined the former Maintenance Services and Manufacturing segments into a single reportable segment, Manufacturing. The combined Manufacturing reportable segment reflects a comprehensive production operation that allows the Company to streamline production processes and resources to better serve customers. Separately, the Company renamed the former Leasing & Management Services segment to Leasing & Fleet Management.
