Read MoreHide Full Article

Key Takeaways

  • Sterling beat Q1 estimates with an adjusted EPS of $3.59 and revenues of $825.7M.
  • STRL's E-Infrastructure (72% of sales) surged to $597.7M, boosted by CEC and mission-critical work.
  • STRL logged a $3.80B signed backlog and raised 2026 revenue, EBITDA and adjusted EPS guidance.

Sterling Infrastructure, Inc. (STRL - Free Report) delivered a strong first quarter of 2026, with adjusted earnings and revenues topping the Zacks Consensus Estimate and rising sharply year over year.

Results were powered by outsized growth in E-Infrastructure Solutions, supported by contributions from the CEC acquisition and solid execution on large, time-sensitive mission-critical work. Additionally, the Transportation Solutions segment benefited from strong performance in the Rocky Mountain market and a strategic shift toward higher-margin projects.

Despite record overall performance, the Building Solutions segment remained a headwind. Revenues increased modestly, but adjusted operating income declined sharply year over year due to tough prior-year comparisons and ongoing affordability pressures that continue to weigh on prospective homebuyers.

Q1 Segmental Discussion of Sterling

E-Infrastructure Solutions

E-Infrastructure Solutions was the clear catalyst, with segment revenues (which consist of 72% of total revenues) jumping to $597.7 million from $218.3 million in the year-ago quarter. Management attributed the performance to strong execution on large mission-critical projects and the added scale from the recently acquired CEC business.

Profitability in the segment also improved meaningfully. Adjusted operating income climbed to $140.3 million from $50.6 million, reflecting the margin profile of mission-critical work and improved mix.

Building Solutions

Building Solutions remained the softer spot. Revenues edged up to $95.1 million from $92 million, but operating income declined to $8.3 million from $14.2 million, as affordability constraints continued to weigh on end markets and pressured segment margins.
