Primoris Services Corp Segments Disclosure

Note 12—Reportable Segments

​

Our Chief Operating Decision Maker (“CODM”), who is our President and Chief Executive Officer, regularly reviews operating and financial performance based on our operating segments. We have aggregated our operating segments into two reportable segments in consideration of the aggregation criteria set forth in ASC 280. Our current reportable segments include the Utilities segment and the Energy segment.

​

Each of our reportable segments is composed of similar business units that specialize in services unique to the segment. Driving the end-user focused segments are differences in the economic characteristics of each segment, the nature of the services provided by each segment, the production processes of each segment, the type or class of customer using the segment’s services, the methods used by the segment to provide the services, and the regulatory environment of each segment’s customers.

​

The classification of certain operating expenses and SG&A expenses for segment reporting purposes can at times require judgment on the part of management. Our segments may perform services across industries or perform joint services for customers in multiple industries. To determine reportable segment profitability, certain allocations, including allocations of shared and indirect costs, as well as general and administrative costs are made. Certain of our fixed assets are used on an interchangeable basis across both reportable segments.

​

The following is a brief description of the reportable segments:

​

The Utilities segment operates throughout the United States and specializes in a range of services, including the installation and maintenance of new and existing natural gas and electric utility distribution and transmission systems, and communications systems.

​

The Energy segment operates throughout the United States and Canada and specializes in a range of services that include engineering, procurement, construction, and maintenance services for entities in the energy, renewable energy and energy storage, renewable fuels, and petroleum and petrochemical industries, as well as state departments of transportation.

​

Corporate and non-allocated costs include corporate facility and property costs; corporate salaries, benefits, incentive compensation and non-cash stock-based compensation; and acquisition and integration costs.

​

Segment Operating Income

​

Operating income is calculated as revenue less cost of revenue and SG&A costs. Cost of revenue includes certain direct and indirect costs such as labor and materials, equipment, depreciation, and subcontractor costs. SG&A includes compensation and benefits for executive, management level and administrative employees, marketing and communications, professional fees, rent for facilities and utilities, amortization, and other general costs required to run our business.

Depreciation and amortization are included within Cost of revenue and SG&A in the Consolidated Statements of Income. A substantial majority of depreciation is reported in Cost of revenue and all amortization is included within SG&A. Depreciation and amortization expense by segment for the years ended December 31, 2025, 2024, and 2023 was as follows (in millions):
