Sterling Infrastructure, Inc. STRL skyrocketed to a new 52-week high mark on Tuesday following its first quarter 2026 financial results on May 4, 2026. STRL stock reached a new 52-week high of $807.30 and pulled back to $806.00 at the end of the trading session. During the trading hours of May 5, STRL stock surged 52.2%, reflecting a powerful combination of earnings outperformance, sharply improved forward outlook and exceptional visibility into long-term growth.
In the first quarter of 2026, Sterling’s adjusted earnings per share (EPS) and revenues significantly topped the Zacks Consensus Estimate by 56.8% and 41.1% and grew year over year by a whopping 120% and 92%, respectively. The exceptional quarterly performance stemmed from the booming demand for data centers, semiconductor facilities and other mission-critical projects.

As of March 31, 2026, STRL’s backlog rose 78% year over year to $3.8 billion, while the combined backlog surged 131% to $5.15 billion. Including unsigned awards and future-phase opportunities, total visible work reached around $6.5 billion, giving investors unusually high confidence in sustained revenue growth. Mission-critical projects now account for more than 90% of the backlog, positioning Sterling directly in the path of long-term secular trends like AI-driven data center expansion. Notably, investors reacted positively to execution strength and strategic momentum, including rapid integration of the CEC acquisition, early realization of cross-selling benefits, and increasing project size and complexity, which are driving further margin expansion. CEC contributed $592 million to the total backlog as of the first quarter of 2026.
Given the robust market trends, Sterling raised its full-year 2026 guidance materially, now expecting about 51% revenue growth and 72% adjusted EPS growth at the midpoint, signaling that the strong first-quarter 2026 performance is part of a broader upward trajectory rather than a one-off.
Sterling vs. EMCOR vs. Comfort Systems: Data Center Race Heats Up
Sterling, alongside big names like EMCOR Group, Inc. EME and Comfort Systems USA FIX, is a key beneficiary of the AI-driven data center supercycle, but they operate at different points in the value chain, shaping their growth profiles.
EMCOR offers the most diversified model, combining strong data center exposure with broader end markets. Its large backlog and expanding presence in hyperscale projects provide stability and consistent growth, though at a more moderate pace compared with Sterling. Conversely, Comfort Systems operates later in the project lifecycle, focusing on mechanical, electrical and cooling systems, areas that are critical as facilities near completion. Its growing exposure to data center investments in modular construction enhances efficiency and scalability, supporting steady earnings growth through 2027-2028.
Overall, Sterling stands out for higher growth potential, Comfort Systems for execution strength in late-cycle demand, and EMCOR for balanced, resilient long-term expansion.
