Sterling Infrastructure, Inc.

Sterling Infrastructure is raising its 2026 capital expenditures to $130-$140 million, up sharply from $77.3 million in 2025, to expand capacity and productivity across its high-growth E-Infrastructure business. The spending targets an upsized equipment fleet, electrical prefabrication facilities including the ramp-up at CEC Facilities Group, and employee recruiting and training to ease capacity constraints in its electrical business. The investment follows E-Infrastructure revenues that surged 192% year over year in the second quarter of 2026, with signed backlog, unsigned electrical awards and future-phase site-development opportunities exceeding $6 billion. Mission-critical projects including data centers, semiconductor facilities and large manufacturing projects made up more than 92% of E-Infrastructure signed backlog, and Sterling expects E-Infrastructure revenues to grow more than 100% in 2026 with adjusted operating margins in the mid-20% range. The company's consolidated revenue outlook stands at $4-$4.15 billion, and its 2026 and 2027 earnings estimates have risen over the past 60 days to $20.02 and $25.79 per share, implying year-over-year growth of 84% and 28.8%.

Sterling Infrastructure's expanding semiconductor work could become a significant catalyst for its E-Infrastructure Solutions business as it moves beyond data center construction. Management said work on a large Northeast semiconductor project is running ahead of schedule, with significant revenues expected in the third quarter of 2026, and noted an initial scope award for an electric vehicle plant in Atlanta, with several additional opportunities possibly awarded in 2026 or early 2027. The push comes as E-Infrastructure revenues jumped 192% year over year in the second quarter of 2026, with mission-critical projects including data centers, large manufacturing facilities and semiconductor projects accounting for more than 92% of signed backlog. Sterling now expects E-Infrastructure revenues to grow more than 100% in 2026, including contributions from CEC and Stone Ridge, while its legacy site development business is expected to grow roughly 70% or more. Earnings estimates for 2026 and 2027 have risen over the past 60 days to $20.06 and $25.81 per share, implying year-over-year growth of 84.4% and 28.7%, and the stock has surged 66.9% year to date while trading at a forward 12-month price-to-earnings ratio of 21.2.

Sterling Infrastructure, Inc. is facing a capacity constraint in its fast-growing E-Infrastructure business, as electrical demand has filled its CEC electrical operation's available capacity in about 90 days, far faster than the roughly one year originally expected. In the second quarter of 2026, CEC revenues increased 140% year over year, while E-Infrastructure revenues surged 192%. CEO Joe Cutillo said CEC could grow even faster with an additional 1,000 to 2,000 electricians, and the company is investing in recruiting, training, and prefabrication facilities. To bridge the gap, Sterling plans to pursue small-to-mid-sized acquisitions to expand capabilities, geographic reach, and capacity, backed by a $181 million net cash position and a revolving credit facility expanded to $1.5 billion through July 2031. The opportunity is substantial, with E-Infrastructure backlog, unsigned electrical awards, and future-phase opportunities exceeding $6 billion, of which mission-critical work represents over 92% of signed backlog. Competitors EMCOR Group and Quanta Services are also expanding through acquisitions and workforce investments, with EMCOR highlighting five electrical businesses generating about $625 million in trailing-12-month revenues and $105 million in EBITDA, and Quanta adding more than 15,000 employees over the past year while investing roughly $250 million annually in training.

Sterling Infrastructure's shares have fallen 15.8% since its second-quarter earnings report, underperforming the S&P 500, despite strong results and raised guidance. The company reported adjusted earnings of $5.80 per share, beating the consensus estimate of $5.20, and revenues of $1.17 billion, up 90.1% year over year and surpassing expectations. Growth was driven by its E-Infrastructure Solutions segment, which accounted for 78% of total revenues and saw revenues jump to $905 million from $310.4 million. Sterling raised its full-year 2026 revenue guidance to $4-$4.15 billion from $3.70-$3.80 billion and adjusted earnings guidance to $19.70-$20.30 per share from $18.40-$19.05.

Sterling Infrastructure's Building Solutions segment is expected to face a tougher 2026 as elevated mortgage rates and affordability pressures weigh on residential construction, with second-quarter revenues down 1% year over year and adjusted operating margin at 9.9%. Management projects modest revenue declines and high-single-digit to low-double-digit margins for the segment, but the company is pivoting toward its higher-margin E-Infrastructure segment, where demand remains strong across data centers and semiconductor facilities. Sterling ended the second quarter with $4.3 billion in backlog, up 116% year over year, and combined backlog of $5.6 billion, providing visibility despite housing softness. The company's E-Infrastructure revenues are expected to grow more than 100% in 2026, positioning it well against peers like EMCOR and KBR. STRL shares have climbed 13.7% in the past six months, and earnings estimates for 2026 and 2027 have risen to $20.06 and $25.81 per share, implying growth of 84.4% and 28.7%, respectively.

He described both companies as tied to key bottlenecks in the massive data center build-out, benefiting from capital expenditures on cables, lines, connectors, and hardware.

Small-cap stocks posted a blistering performance in the first half of this year, with the Russell 2000 Index surging 22% through June, its strongest first-half performance since 1991. The index beat the NASDAQ by 9%, its biggest first-half outperformance since 2001, according to the Wall Street Journal. Small caps benefited from a resilient economy, rising earnings, supportive trade policies, infrastructure spending, and reshoring initiatives, while enthusiasm around AI beneficiaries within the small-cap universe also helped lift the indexes. The top-performing companies came from the AI, semiconductor, space, nuclear energy, quantum computing, and biotech sectors. After the Russell indexes rebalanced at the end of June, all 25 of the best-performing Russell 2000 constituents, each having gained at least 250% over the past year, moved into the Russell 1000, according to Bespoke. Looking ahead, potential Federal Reserve interest rate hikes due to elevated inflation could pose headwinds for smaller companies, which often carry heavier debt burdens with floating interest rates and have less access to the bond market. Since its inception in May 2000, the iShares Core S&P Small-Cap 600 ETF has returned more than 1,170%, compared with about 812% for the iShares Russell 2000 ETF, a performance gap largely stemming from the S&P SmallCap 600's built-in profitability requirement, though the Russell 2000 has outperformed over the past year as many companies tied to quantum computing, nuclear energy, and AI are not yet profitable and are excluded from the S&P SmallCap 600.

Sterling Infrastructure's Transportation Solutions segment reported a 10% revenue increase and a 26% rise in adjusted operating income in the first quarter of 2026, driven by strong execution and a favorable mix of higher-margin projects. The segment's backlog reached $1.04 billion, up 20% year over year, providing healthy revenue visibility. Sterling expects low to mid-single-digit revenue growth for the full year, though growth is likely to moderate after an unusually strong first quarter that benefited from favorable weather and earlier-than-expected project starts. The company is reducing exposure to lower-margin highway work in Texas while redeploying equipment and resources to higher-return projects, improving asset utilization and capital efficiency. Transportation Solutions continues to serve as a reliable cash-generating business, supporting investment across Sterling's other growth initiatives.

Share prices across the group have risen 12.6% on average since the latest earnings results.

Sterling Infrastructure is seeing a growing opportunity in Texas as demand for large-scale infrastructure projects accelerates across the state. In the first quarter of 2026, the company pointed to exceptionally strong conditions in Texas, with robust award activity supporting business momentum. Texas contributed meaningfully to recent project wins secured by Sterling's electrical services business CEC, which helped drive a $1.2 billion increase in CEC's combined backlog since year-end 2025. The company indicated that project sizes in Texas are growing rapidly, with some developments expected to span several years. Shares of Sterling have gained 191.4% year to date, and the stock currently carries a Zacks Rank #1, or Strong Buy.

Sterling Infrastructure emerges as the stronger investment over MasTec based on growth metrics, earnings momentum, and technical indicators. Sterling reported a record $3.8 billion signed backlog and $5.15 billion combined backlog in the first quarter of 2026, representing year-over-year growth of 78% and 131% respectively, while its pipeline of high-probability future phase opportunities exceeds $1.3 billion.

MasTec posted a record $20.3 billion backlog and raised its full-year EBITDA guidance to approximately $1.5 billion, but faces project timing risks and regulatory uncertainty. Sterling holds a Zacks Rank #1 (Strong Buy) compared to MasTec's Zacks Rank #3 (Hold).

Zacks Investment Research identified three AI-driven stocks for the second half of 2026 that have already posted triple-digit returns year to date and still carry double-digit upside potential. Sterling Infrastructure, a Zacks Rank #1 Strong Buy, is a major provider of high-density AI-powered data centers and has expected revenue and earnings growth of 59.2% and 77.4% for the current year, with a short-term average price target implying a 9.7% increase from its last closing price of $861.88. Semtech, a Zacks Rank #2 Buy, is benefiting from AI-led data center networking demand and has expected revenue and earnings growth of 29.1% and 55.6% for the current year ending January 2027, with a short-term average price target representing a 29.5% increase from its last closing price of $158.23.

Sterling Infrastructure could be 8.4% undervalued following strong recent earnings and rapid revenue growth, with the most followed analyst narrative pointing to a fair value of $941.17 compared to its last close of $861.88. The consensus price target of $941.17 is based on expectations that by 2029 revenues will reach $4.5 billion, earnings will hit $1.1 billion, and the stock will trade at a PE ratio of 34.9 times, assuming an 8.8% discount rate. However, a Simply Wall St discounted cash flow model estimates a much lower fair value of $469.91, suggesting the stock is overvalued instead. The stock has surged 17.46% over the past 30 days and 114.61% over 90 days, reflecting rapid repricing as its E-Infrastructure business model gains attention. Key risks include a potential slowdown in mega data center and semiconductor projects or underperformance from new acquisitions.

Sterling Infrastructure is recasting its business around E-Infrastructure, focusing on hyperscale data centers and semiconductor facilities. The company reported strong recent quarterly results and holds a sizable project backlog, supported by the integration of CEC Facilities Group. Management expects multi-year revenue and profitability growth tied to this E-Infrastructure focus. The shift moves Sterling from a niche construction player to a key contractor in digital and advanced manufacturing buildouts, with shares at $861.88 and very large gains over one and five years. Concentration in a few fast-growing verticals and large projects raises dependency on a limited group of customers, while peers like Quanta Services and KBR also compete for the same AI and semiconductor spending.

Sterling Infrastructure has received a Zacks Rank #1 (Strong Buy) following significant upward revisions to its earnings estimates. The consensus estimate for the current quarter has risen 15.4% over the last 30 days to $5.39 per share, representing a 100.4% increase from the year-ago period. For the current fiscal year, the estimate has increased 2.9% to $19.31, and for the next fiscal year, it has risen 5.5% to $27.43. The company also posted a 41.05% revenue surprise in its most recent quarter, with sales of $825.67 million, and has beaten consensus EPS estimates in each of the trailing four quarters.

Sterling Infrastructure shares have jumped 181% over the past six months to $849.51 per share, driven by strong quarterly results. The company’s revenue grew at a 14.8% compounded annual rate over five years, outpacing the average industrial firm. Its free cash flow margin averaged 15.6% over the same period, ranking among the best in the sector. Return on invested capital has also risen significantly, signaling expanding competitive advantages. The stock now trades at 44.7 times forward earnings.
