Effective for the quarter and year ended December 31, 2021, the Company implemented operational changes in how its Chief Operating Decision Maker (“CODM”) manages its businesses, including resource allocation and operating decisions. As a result of these changes, the Company now has three reporting segments, representing the individual businesses that are run separately under the new structure: Rail, Technologies, and Services; Precast Concrete Products; and Steel Products and Measurement. The Company has revised the information for all periods presented in this Quarterly Report on Form 10-Q to reflect these reclassifications.</span></div>
