Note 11 –Segment Information

The Company’s reportable segments are those that are based on the Company’s method of internal reporting and management of the business. The Company provides a full spectrum of construction services across most of the United States throughtwo reportable, operating segments:

T&D: Contracting services for the construction and maintenance of overhead and underground electrical, gas, communication infrastructure and transportation-related lighting, as well as the manufacture and distribution of overhead and underground transmission line construction equipment and tools.

The Company’s Chief Operating Decision Maker (“CODM”) is the Company’s chief executive officer (“CEO”). The Company’s CEO evaluates each reportable segment’s performance, allocates resources and makes decisions based on segment operating income, which is the segment measure of profitability. The CODM uses segment operating income to analyze the results of each reportable segment individually and by comparing the results of the segments with each other. This comparison between segments helps drive decision-making regarding resource allocation and compensation of employees. Segment operating income is also considered when creating the annual budget plan, as well as the forecasting process, including the allocation of capital for uses such as capital expenditures.

All intercompany balances and transactions between the businesses comprising the Company have been eliminated in the unaudited condensed consolidated financial statements.
