Segment Information
Legence reports its results under two reportable segments: 1) Engineering & Consulting, and 2) Installation & Maintenance. Segments are presented according to the nature of the business activities, and reflect the Company’s consideration of financial information provided to the chief executive officer, who is the Chief Operating Decision Maker ("CODM"). The CODM primarily uses gross profit to assess performance and allocate resources, including decisions such as the annual budget review and approval, allocation of resources to hire additional key personnel, entering new markets and development of new technologies, evaluating executive performance, and determining performance-related bonus plans in each segment.
Engineering & Consulting: The Engineering & Consulting segment designs HVAC and other MEP systems for buildings, develops strategies to reduce energy usage and make buildings more sustainable and provides program and project management services for customers’ installation and retrofit projects. Within this segment, there are two primary service offerings – Engineering & Design and Program & Project Management.
Installation & Maintenance: The Installation & Maintenance segment fabricates and installs HVAC systems, process piping and other MEP systems in new and existing industrial, commercial and institutional buildings and provides ongoing preventative and corrective maintenance services for those systems. Within this segment, there are two primary service offerings – Installation & Fabrication and Maintenance & Service.
All intercompany transactions are eliminated in the Company's Consolidated Statements of Operations.

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.
