Sterling Infrastructure’s Q1 2026: Acquisition-Driven Ramp Pushes Revenue and Backlog to Fresh Highs

Overview: A Revenue and Backlog Acceleration Fueled by CEC

STERLING INFRASTRUCTURE, Inc. (Nasdaq: STRL) kicked off 2026 with a first quarter that looks like a deliberate plan to turn a pile of contracts into cash, not a fluke. Revenue rose to $825.7 million, up 92% year over year, driven in large part by the recently acquired CEC business contributing $156.1 million to quarterly revenue. Net income reached $96.0 million, or $3.09 per diluted share, with adjusted net income of $111.3 million and adjusted earnings per diluted share of $3.59. EBITDA of $155.2 million on GAAP basis grew 115%, while adjusted EBITDA came in at $166.6 million (both metrics labeled with the customary one‑off tweaks).

In total, the results push Sterling’s backlog to $3.80 billion as of March 31, 2026, with combined backlog—counting CEC’s contribution—reaching $5.15 billion. That latter figure represents a 131% increase from the prior year, and if you back out CEC’s contribution, backlog still climbs 46% year over year. The acquisition’s imprint is clearly visible in both revenue mix and forward visibility.

Key Metrics at a Glance

• Revenue: $825.7 million, up 92% year over year; CEC contributed $156.1 million.

From a forward-looking perspective, Sterling raised its full-year 2026 guidance, signaling management’s confidence in sustaining the pace of revenue growth and backlog expansion into the balance of the year. In the language of earnings reports, this is the classic “raised revenue forecast” moment, albeit with the caveat that a sizable portion of the gains sits on the back of an acquired business unit.

Where It Matters: Margins, Backlog Quality, and Cash Use

The margin story here is twofold. First, the GAAP numbers show a robust top-line expansion that translates into meaningful profit, even as acquisitive growth injects integration costs and mix changes. Second, the elevation in adjusted metrics—net income, EPS, and EBITDA—signals that Sterling’s management is curating a value-added path through the CEC acquisition, not simply chalking up revenue by fiat. The adjusted figures, in particular, suggest a focus on operating leverage and synergy realization as the quarter progresses.

Backlog as a metric remains the lifeblood of a contracting and infrastructure-focused business. Sterling’s backlog of $3.80 billion, rising to a combined $5.15 billion, implies strong revenue visibility for the next several quarters. The data point that CEC contributed $1.88 billion to combined backlog, with backlog excluding CEC up 46%, underscores how acquisitions can dramatically reshape forward outlook—while elevating execution risk. The question for investors is whether the company can translate this sizable backlog into consistent near-term revenue and margin expansion as integration proceeds.

Capital Allocation: Buybacks on the Margin, Not the Backswing

On the capital side, Sterling deployed cash to opportunistic share repurchases, buying back $12.3 million worth of stock at an average price of $305.14 per share. In a world where project delays and supply chain hiccups can erase visibility, returning capital to shareholders while sustaining a growth program via acquisitions can be a delicate balance. Here, management appears to be signaling confidence in both the platform’s growth trajectory and the durability of current earnings power.

Outlook: A 2026 Narrative That Hinges on Execution

The headline—“Sterling Reports Record First Quarter Results and Raises Full Year 2026 Guidance”—hints at a company intent on extending a positive trajectory. The press materials emphasize record performance in the context of an expanding backlog and higher revenue from the CEC acquisition. For investors, the relevant questions are whether the raised guidance translates into sustained operating leverage and cash generation, and whether the momentum is broad across Sterling’s market segments and regions or concentrated in specific contracts.

In sector terms, the story resembles a common thread: acquisitions altering the growth calculus, backlog becoming the new currency of visibility, and management signaling that the pace can be maintained. Analysts will compare the reported EPS against the EPS consensus and weigh the revenue forecast against external macro assumptions about infrastructure spend, project timelines, and material costs. The real test will be whether Sterling can convert higher backlog into steady revenue growth and margin expansion in the second and third quarters, without letting integration drag on the cost base.

Outlook for Peers and the Sector

Sterling’s Q1 performance is a data point in a broader infrastructure- and construction-services environment that has shifted toward acquisitions-as-growth, higher backlog accumulation, and improved cash conversion. Peers with similar exposure to industrials and civil infrastructure may view Sterling’s results as a signal to lean into tuck-in acquisitions that accelerate scale and backlog, provided they can maintain integration velocity and cost discipline. The EPS trajectory—through GAAP and non-GAAP lenses—will be a key comparator across the sector, and the revenue forecast will be watched closely for signs of backlog realization versus new project wins in a potentially uneven macro backdrop.

Final take: A Deliberate Push Rather Than a Flash in the Pan

Sterling’s Q1 2026 narrative blends a robust revenue beat with a substantial backlog expansion, anchored by the CEC acquisition. The numbers suggest a company transitioning from integration-mode to execution-mode, and the raised guidance hints at management’s confidence in sustaining this path. While the sustainability of margins and the cadence of new wins will shape the stock’s near-term trajectory, the fundamentals—EPS (GAAP and adjusted), earnings power, and cash flow—paint a picture of a platform that could potentially deliver earnings surprise to the upside if the recovery in project demand and execution efficiency hold.

Bottom line for investors: STRL’s first-quarter results are more than a pulse on quarterly earnings; they’re a signal about the durability of a growth strategy built on acquisitions, combined with a focus on cash generation and shareholder-friendly capital allocation. The market will now test these signals against the EPS consensus and revenue forecast as more quarters roll in, and the sector—traditionally sensitive to project delays and commodity cycles—will be watching closely how Sterling translates backlog into actual revenue and steady margin gains.
