Sterling Infrastructure said it closed on its acquisition of Stone Ridge Contracting, a Pocatello, Idaho-based site development contractor, adding a business expected to produce $180 million to $200 million of full-year 2026 revenue.
Stone Ridge will be folded into Sterling’s E-Infrastructure Solutions segment, expanding that unit’s geographic reach into Idaho, Oregon, North Dakota, Washington and Texas. Sterling said the deal strengthens its footprint in the Pacific Northwest and Texas, two areas it has targeted for expansion.
Stone Ridge’s expected 2026 EBITDA margin is in the mid-teens. Sterling said the purchase price multiple was within its typical range for site development assets. The upfront payment included cash and Sterling stock, and the seller also has an earn-out tied to EBITDA targets through Dec. 31, 2031.
Sterling said it will update full-year 2026 guidance when it reports second-quarter results, reflecting only the partial-year contribution from Stone Ridge. The leadership team at Stone Ridge will remain in place after the transaction. As a result of these announcements, the company's shares have moved -4.0% on the market, and are now trading at a price of $856.21. For more information, read the company's full 8-K submission here.
