Sterling nearly doubled its sales in the three months ended June 30, and kept more of each dollar.
Revenue reached $1.2 billion, up 90.1% from the comparable three months a year earlier. Gross margin widened to 24.8% from 23.3%, while net income more than doubled to $155.8 million. On the surface, this is a simple scale story: more work, better margins, much more profit.
The cash balance is the part that refuses to fit neatly. Cash fell to $464.5 million from $699.4 million, a 33.6% decline, even as diluted earnings per share rose to $5 from $2.31.
Management attributes the operating-income increase mainly to higher volume from large mission-critical projects, with a newly acquired electrical and mechanical business adding another layer.
"The increases in operating income were primarily driven by higher volume from large mission-critical projects, and partly attributable to $25.2 million (inclusive of $2.3 million of intangible amortization) and $37.5 million (inclusive of $4.6 million of intangible amortization) of contributions for the three and six months ended June 30, 2026, respectively, from the electrical and mechanical business acquired late in the third quarter of 2025."

That acquired operation contributed $239.9 million of revenue in the three months, roughly one-fifth of the total. The latest growth therefore combines large-project volume with a full-period contribution from a business Sterling did not own in the comparable period.
The cash movement has a more specific explanation than the income statement does. Sterling’s financing cash outflow included $35.3 million of share repurchases, $11.9 million of taxes withheld on vested equity awards, $7.8 million of earn-out payments, and $7.5 million of term-loan repayments.
"The financing cash outflow during the period was primarily driven by $35.3 million for the repurchase of common stock, $11.9 million for withholding taxes paid on 28 the net share settlement of vested equity awards, $7.8 million of earn-out payments, and $7.5 million of repayments on the Term Loan Facility, partly offset by $14.7 million of capital contributions from noncontrolling interest owners."

So the lower cash balance is not a single operating verdict. It reflects financing uses, while the company also carried a heavier investment load: capital spending rose 122.8% year over year, and free-cash-flow margin declined 0.3 percentage points. Contract assets increased $55.1 million from year-end, primarily from higher unbilled revenue and retainage.
Sterling says contract-capital movements depend on the project mix, seasonality, the timing of awards, customer payments, and billings as work is completed. That makes cash generation partly a calendar-and-contract question, not just a function of the new profit level.
The margin expansion also has history behind it. Sterling’s annual operating margin rose from 2.7% in 2017 to 16.3% in 2025, and reached 18.8% in the latest three months. At the latest close of $612.11, the stock carried a 65.3x trailing P/E, with cash timing still in view in the latest filing.
Sterling’s next quarterly report will need to put another period beside this one: cash, contract assets, capital spending, and the contribution from the acquired electrical and mechanical business. What will Sterling’s next quarterly report disclose about the cash effect of project timing and contract capital?
Sterling’s 2026 10-Q attributes operating-income growth to project volume and the acquired electrical and mechanical business, while linking cash movement to financing outflows and contract-capital changes.
