STRL earnings analysis

What we found in STRL's 10-Q: the parts that mattered, the offsets in the same document, and what the company said about what comes next.

Our reading of the filing · Free to read, no account needed

Sterling delivered an exceptional Q2, with revenue up 90% to $1.168 billion, GAAP diluted EPS of $5.00, and operating margin expanding to 18.8%. E-Infrastructure was the central driver, with revenue up 192%, while backlog grew to $4.33 billion and combined backlog reached $5.62 billion. Offsetting factors are shrinking Transportation volume, continued residential weakness in Building Solutions, acquisition/integration exposure, and a $68.1 million first-half Contract Capital cash use.

What stood out

The parts that mattered.

Pulled out of the filing itself, with the figures the company reported.

Revenue and EPS accelerated sharply
Q2 revenue reached $1.168 billion, up $553.7 million (90%) from $614.5 million in Q2 2025 and approximately 41% from $825.7 million in Q1 2026. GAAP diluted EPS was $5.00, versus $2.31 a year ago and $3.09 in Q1 2026.
Margins expanded despite acquisition costs
Gross margin expanded 150 basis points year over year to 24.8% from 23.3%, while operating margin rose 180 basis points to 18.8% from 17.0%. The operating margin also improved from 16.7% in Q1 2026.
E-Infrastructure drove growth
E-Infrastructure revenue increased 192% to $905.0 million, driven by large mission-critical projects. The late-Q3 2025 electrical and mechanical acquisition supplied $239.9 million of quarterly revenue and $25.2 million of operating-income contribution, including $2.3 million of intangible amortization.
Backlog rose 44% with strong awards
Backlog increased to $4.33 billion at June 30 from $3.01 billion at December 31, 2025; combined backlog including unsigned awards reached $5.62 billion versus $3.31 billion. Six-month backlog and combined-backlog book-to-burn ratios were 1.7x and 2.3x, respectively.
Cash conversion remained strong
Six-month operating cash flow nearly doubled to $328.0 million from $170.3 million. After $69.6 million of capital-equipment purchases, calculated free cash flow was $258.4 million, equivalent to 21.6% of six-month revenue.
Net cash strengthened and debt was repaid
Cash and cash equivalents rose $73.7 million in the first half to $464.5 million. The company paid off all $285 million of term-loan principal and interest outstanding on July 2, 2026.
What to watch

And the other side of it.

The offsets in the same document — the things a summary that only listed the good news would have left out.

No material risk-factor updates
Item 1A states there were no material changes from risk factors in the 2025 Form 10-K. Existing risks remain relevant, including project-cost escalation, funding, labor, customer-concentration, acquisition, and joint-venture exposures.
Transportation volume contracted
Transportation revenue fell $40.1 million, or 20%, year over year to $156.7 million. Although operating margin improved to 18.0% from 13.2%, the volume decline reflects lower heavy-highway and other revenue.
Residential downturn pressures Building
Building Solutions revenue declined $0.8 million to $106.5 million and operating income declined $1.4 million to $8.5 million; its operating margin compressed to 8.0% from 9.2%. Management anticipates residential demand will remain muted in the near term because of affordability pressure.
Receivables increased working-capital needs
Accounts receivable consumed $242.4 million of cash during the first six months, and net Contract Capital was a $68.1 million use of cash. This working-capital requirement was substantially above the $24.6 million use in the prior-year period.
Acquisition integration and control scope risk
Stone Ridge required $140.0 million of cash consideration and carries an earn-out opportunity of up to $15.0 million. In addition, CEC and Stone Ridge represented 32.5% of total assets and 20.4% of quarterly revenue excluded from management's June 30 controls assessment under the newly-acquired-business SEC accommodation.

What they said about what is next.

The 10-Q does not provide quantitative revenue or EPS guidance. Management discusses favorable long-term E-Infrastructure opportunities and expects muted near-term Building Solutions demand; quantitative outlook was deferred to the August 3 earnings release/call.
