Record backlog near $3B and $4.5B pipeline support sustained growth and cash flow strength.
Sterling Infrastructure, Inc. (STRL - Free Report) continues to deliver a compelling growth narrative, but its strong cash flow generation may still be underappreciated by investors. It exited 2025 on a high note, generating a robust $440 million in operating cash flow, supported by disciplined project selection, margin expansion and strong execution. Notably, this cash generation aligns with STRL’s strategy of prioritizing high-return, mission-critical projects, particularly within its fast-growing E-Infrastructure segment.
A surge in demand for data centers, semiconductor facilities and large-scale manufacturing projects is aiding prospects for the E-Infrastructure segment, resulting in 58.8% year-over-year revenue growth in 2025. During the year, Sterling’s adjusted EBITDA grew year over year by 47%, with margins surpassing 20% for the first time, and adjusted EPS surging 53% to $10.88. This combination of strong profitability and cash conversion underscores the company’s operational efficiency and pricing discipline.
Importantly, the company’s balance sheet remains a key strength. Sterling ended the year with a net cash position, providing ample flexibility to pursue acquisitions, invest in growth and return capital through share repurchases. In 2025 alone, it deployed $74 million toward buybacks, signaling confidence in its long-term outlook. Looking ahead, visibility remains solid, backed by a record backlog of approximately $3 billion and a broader opportunity pipeline nearing $4.5 billion. Strong demand from data centers, semiconductor and manufacturing projects is expected to sustain growth momentum and support continued cash flow strength.
While investors have rewarded Sterling’s growth, the durability and scalability of its cash flow, driven by a favorable mix, execution and secular tailwinds, may not yet be fully priced in, making its story worth a closer look.
Sterling, EMCOR, Primoris Services: Who Wins the Cash Flow Race?
Sterling is benefiting from powerful tailwinds such as data center expansion, grid modernization and U.S. infrastructure spending, alongside renowned names like EMCOR Group, Inc. (EME - Free Report) and Primoris Services Corporation (PRIM - Free Report) .
Sterling stands out for its high-margin, cash-generative model, driven by mission-critical E-Infrastructure projects. Meanwhile, EMCOR differentiates itself through recurring service revenues and scale, particularly in mechanical and facilities services. This drives consistent cash flows, high returns on capital and industry-leading shareholder value creation, reflected in strong long-term total shareholder returns and a net cash balance sheet.
On the other hand, Primoris Services offers large-scale exposure to energy, utilities and renewables, backed by a nearly $11.9 billion backlog and solid operating cash flow generation. However, its margins are lower and more volatile, and execution risks in energy markets can impact near-term cash flow consistency.
Overall, EMCOR leads in stability and shareholder returns, Sterling in profitability and cash efficiency, while Primoris provides scale and long-term backlog visibility with comparatively higher cyclicality.
