Sterling stock tumbled 5.6% during yesterday’s trading hours and moved further down 2% in the after-hours.

Sterling’s Growth Momentum With Stone Ridge Deal

Stone Ridge is a Pocatello, ID-based heavy civil, concrete and construction management services provider that strengthens STRL’s hold on high-growth markets of Idaho, Oregon, North Dakota, Washington and Texas. The services of Stone Ridge stretch across booming sectors, including data centers, mining and industrial infrastructure.

Notably, in 2026, Stone Ridge is expected to generate revenues between $180 million and $200 million, with EBITDA margins projected to be in the mid-teens. Sterling will be reporting its updated 2026 guidance in the second-quarter 2026 financial reports, highlighting the partial-year contributions from the Stone Ridge acquisition.

The purchase price includes a combination of cash and Sterling common stock, with Stone Ridge having an earn-out opportunity, contingent upon meeting certain EBITDA targets on or before Dec. 31, 2031.

STRL’s Buyout Efforts Bode Well

Sterling’s acquisition strategy is evolving beyond simple scale expansion and is increasingly becoming a competitive differentiator. The acquisition of CEC has significantly strengthened Sterling’s presence in high-growth, mission-critical markets such as AI-driven data centers, semiconductor fabrication facilities and advanced manufacturing projects. In the first quarter of 2026 alone, CEC contributed $156 million in revenues and nearly $1.9 billion to the combined backlog, accelerating Sterling’s growth trajectory and enhancing earnings visibility.

More importantly, the deal enables STRL to offer integrated site-development and electrical-services solutions, creating cross-selling opportunities and positioning the company as a one-stop partner for complex infrastructure projects. This integrated model is already generating results, with the company executing data center campuses that combine both capabilities.

Moreover, Sterling’s strong balance sheet provides ample flexibility to pursue further strategic acquisitions while continuing to invest in organic growth initiatives. It ended the first quarter of 2026 with $511.9 million in cash and cash equivalents, generated a robust operating cash flow of $165.6 million and maintained a manageable debt profile. This financial strength enables Sterling to fund acquisitions without overleveraging the balance sheet, while also supporting capital expenditures, share repurchases and future expansion opportunities.
