Read MoreHide Full Article

Key Takeaways

  • Sterling shares fell 34.8% in three months despite Q2 revenue rising 90% and adjusted EPS climbing 116%.
  • Mission-critical demand drove E-Infrastructure revenue up 192%, with 92% of backlog tied to such projects.
  • More than $7B of potential work visibility and net cash position support Sterling's expansion plans.

Sterling Infrastructure, Inc. (STRL - Free Report) shares have plummeted 34.8% over the past three months, sharply underperforming the Zacks Engineering - R and D Services industry’s 8.3% decline and the Zacks Construction sector’s 4.9% decrease. The S&P 500 gained 5.3% over the same period. STRL is also trading below both its 50-day and 200-day moving averages, pointing to weak near-term market sentiment.

However, Sterling’s recent operating performance tells a different story. Second-quarter revenues increased 90% year over year, while adjusted earnings per share (EPS) rose 116% to a record $5.80. Adjusted EBITDA advanced 104%, with adjusted EBITDA margin reaching 22%. The company also ended the quarter with $4.3 billion of signed backlog and $5.6 billion of combined backlog. Including more than $1.4 billion of high-probability future-phase opportunities, Sterling has visibility into more than $7 billion of potential work.

Mission-Critical Demand: A Major Tailwind for STRL Stock

Sterling’s growing exposure to mission-critical infrastructure remains the strongest part of its investment case. E-Infrastructure revenues surged 192% in the second quarter, supported by data centers, semiconductor facilities and other large projects. Mission-critical projects accounted for 92% of E-Infrastructure backlog, highlighting the company’s increasing focus on markets backed by strong capital spending.

Management indicated that data-center projects are becoming larger, longer in duration and spread across more markets. Existing projects are also expanding beyond their original scopes, with some of this potential work not yet reflected in backlog. CEC has broadened Sterling’s electrical capabilities, while Stone Ridge adds capacity and expands its geographic reach.

Sterling expects E-Infrastructure revenues to grow more than 100% in 2026, including acquisitions. Legacy site-development revenues are expected to grow at rates approaching 70% or higher, while adjusted operating margins are projected in the mid-20% range. These trends provide a solid foundation for continued growth into 2027.

STRL’s Backlog & Financial Strength Expand Growth Visibility

Sterling’s backlog provides strong visibility despite the recent stock weakness. Signed backlog increased 116% year over year and 50% organically. The company’s presentation shows that backlog, unsigned awards and future-phase work together create visibility into more than $7 billion of opportunities.

Sterling also has the financial resources to support expansion. The company ended June with $464 million in cash against roughly $284 million of debt, resulting in a net cash position. Sterling subsequently expanded its revolving credit facility to $1.5 billion and extended its maturity to July 2031.

The additional liquidity gives Sterling room to invest in equipment, add workforce capacity and pursue acquisitions. Management is increasing fleet investments and expanding prefabrication capabilities to improve productivity. It has also indicated that additional acquisitions could become important as data-center customers require more capacity.

Estimate trends provide another positive signal. Over the past 30 days, the Zacks Consensus Estimate for 2026 EPS has increased to $20.06 from $19.89, implying 84.4% year-over-year growth. The revenue estimate suggests 65.2% growth in 2026. For 2027, the consensus estimate calls for EPS and revenue growth of 28.7% and 19.5%, respectively.

What Could Keep Pressure on STRL Shares?

Not all parts of Sterling are growing at the same pace. Transportation Solutions revenues declined 20% in the second quarter as resources were shifted toward higher-margin E-Infrastructure projects. Building Solutions revenues slipped 1%, while adjusted operating income declined 11% amid relatively flat homebuilder activity. Management expects housing affordability pressures to keep market conditions challenging through 2026.

Backlog can also be uneven from quarter to quarter. Management has cautioned that strong revenue conversion and the timing of new project awards could lead to a sequential backlog decline even when underlying demand remains healthy. Weather could slow activity on major semiconductor work during the fourth quarter.

Execution is another factor to watch. Sterling is rapidly adding people, equipment and acquired businesses to meet demand. Maintaining project execution and margins while expanding into new markets will be important.

Valuation is not yet an outright bargain either. STRL trades at 20.9X forward 12-month earnings, below its industry’s 25.51X but above its five-year median of 17.62X. Thus, the sell-off has made the valuation more reasonable, but the stock is still not cheap compared with its own historical norm.

How Sterling Compares With Quanta, MasTec and Granite

Quanta Services (PWR - Free Report) , MasTec (MTZ - Free Report) and Granite Construction (GVA - Free Report) provide useful comparisons. Quanta shares have slipped only 1.8% over the past three months compared with Sterling’s 34.8% decline, but Quanta trades at a much higher 35.19X forward P/E. MasTec stock lost 26.7%, also holding up better than Sterling, while MasTec’s 21.05X multiple is almost identical to Sterling’s 20.9X. Granite stock has dipped 12.3% and trades at 14.2X, making Granite the cheapest of the four.

Quanta offers stronger share-price momentum but demands a sizable valuation premium. MasTec combines broad infrastructure exposure with a valuation close to Sterling’s, while Granite offers a lower valuation but less direct exposure to the mission-critical data-center theme. Sterling’s sharper decline has improved its relative appeal, though Quanta, MasTec and Granite have all shown better recent stock-price resilience.

Is Sterling’s 35% Sell-Off Overdone?

Sterling’s fundamental performance suggests that the scale of the stock decline may be greater than the deterioration in its business outlook. Strong mission-critical demand, expanding backlog, healthy cash generation, rising earnings estimates and growing data-center and semiconductor exposure support the long-term case.

Wall Street sentiment remains positive as well. Sterling has an ABR of 1.22, with eight of nine brokerage recommendations at Strong Buy. The average price target of $829.13 implies 65.1% upside from the latest closing price.

Still, weak technical momentum, an above-historical valuation, housing-market pressure and the execution demands of Sterling’s rapid expansion argue against chasing the stock solely because it has fallen sharply. The current Zacks Rank #3 (Hold) appropriately reflects this balance. Existing investors may consider staying patient, while prospective buyers may want to see greater share-price stability or a more compelling valuation before taking a more aggressive position.
