Their commitment and dedication continue to deliver excellent results for our customers, provide increasing opportunities for our employees, and bring crucial services to our communities. Careful discipline and great execution resulted in quarterly EPS that doubled compared to the same quarter last year. In addition to increased revenue and earnings, we also achieved over $400 million of quarterly cash flow.”

Specifically, we achieved a third consecutive same-store backlog increase that exceeded $1 billion, with backlog growing by more than $2 billion this quarter. Backlog is just under $12 billion, and it has roughly doubled since the beginning of the year. In addition, in 2025 both our net income and our cash flow eclipsed $1 billion.”

Mr. Lane concluded, “We continue to experience persistent demand and strong pipelines. Given the strength and excellence of our workforce, we are optimistic about our prospects for 2026.”

— Financial tables follow —

Note: The Company defines adjusted earnings before interest, taxes, depreciation, and amortization (“Adjusted EBITDA”) as net income, provision for income taxes, other expense (income), net, changes in the fair value of contingent earn-out obligations, interest income, net, gain on sale of assets, goodwill impairment, other one-time expenses or gains and depreciation and amortization. Other companies may define Adjusted EBITDA differently. Adjusted EBITDA is presented because it is a financial measure that is frequently requested by third parties. However, Adjusted EBITDA is not considered under generally accepted accounting principles as a primary measure of an entity’s financial results, and accordingly, Adjusted EBITDA should not be considered an alternative to operating income, net income, or cash flows as determined under generally accepted accounting principles and as reported by the Company.

Note: Free cash flow is defined as cash flow from operating activities less customary capital expenditures, plus the proceeds from asset sales. Other companies may define free cash flow differently. Free cash flow is presented because it is a financial measure that is frequently requested by third parties. However, free cash flow is not considered under generally accepted accounting principles as a primary measure of an entity’s financial results, and accordingly, free cash flow should not be considered an alternative to operating income, net income, or cash flows as determined under generally accepted accounting principles and as reported by the Company.
