What stood out

The parts that mattered.

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

Strong cash generation
Net cash provided by operating activities was $388,828,000 and free cash flow was $242,229,000 (capex purchases of $147,473,000) in the quarter.
Backlog supports near-term revenue
Backlog as of March 31, 2026 was $12,454,726,000, up 80.8% year-over-year from $6,888,818,000 (and +4.3% sequentially from $11,944,601,000 at December 31, 2025).
Segment strength — electrical notably robust

Net income was $370,378,000 in Q1 2026 versus $169,289,000 in Q1 2025 (increase of $201,089,000).
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.

Rising labor/SG&A pressure
SG&A increased to $268,996,000 (up $74,122,000, +38.0% YoY) and management attributes $54,000,000 of the same-store SG&A increase to higher compensation costs.
Contingent earn-out volatility
Expense from changes in the fair value of contingent earn-out obligations was $10,370,000 in Q1 2026 (versus $3,758,000 in Q1 2025), an increase of $6,612,000.
Higher effective tax rate this quarter
Provision for income taxes was $111,768,000 in Q1 2026 (effective tax rate 23.2%), up from $38,723,000 (18.6% effective rate) in Q1 2025.
Supply-chain and cost pressure persists
Management states it anticipates continued cost pressures and intermittent supply delays; to mitigate it is ordering earlier and collaborating with customers (no numeric relief signaled).
Backlog convertibility caution
While backlog is $12,454,726,000, management discloses backlog predictive value is limited to the near term and may not fully convert to revenue beyond six to 12 months.
No material risk-factor changes disclosed
The filing refers investors to Item 1A in the 2025 Form 10-K and does not identify new or materially changed risk factors in this 10-Q.
