The vote closed Friday. Arcosa stockholders approved CRH plc’s acquisition of the company at a special meeting on September 4, clearing the last shareholder hurdle on a deal signed in June.
CRH is buying 100% of Arcosa in cash at $150 per share, which put the transaction at roughly $8.5 billion under the June 22 merger agreement. Closing is now expected in the first quarter of 2027, subject to customary conditions including the regulatory approvals. Certified vote results go on a Form 8-K; what was reported Friday is preliminary.
What CRH is buying
Arcosa is a Dallas company that supplies aggregates, construction materials and engineered structures, which is a broader mix than a pure quarry business. CRH already runs one of the largest aggregates positions in North America, and this adds materially to it, along with the infrastructure-products side.
Aggregates consolidation has a specific logic that doesn’t apply to most building-products M&A: rock is heavy, hauling it is the dominant cost, and a quarry’s economics are set almost entirely by how far it sits from the pour. You can’t build a competing pit next to an incumbent, because permitting one takes a decade if it happens at all. So buying reserves near growth corridors is the only practical way to grow, and the reserves themselves appreciate as the surrounding land gets entitled for everything except quarrying.
Why the timing is not an accident
Public infrastructure spending is the most durable demand in the U.S. construction market right now, and it consumes aggregates at a rate that vertical construction doesn’t come close to. A highway program buys rock for decades. An office tower buys it once.
The $8.5 billion figure comes from CRH’s own June announcement rather than Friday’s vote release, and the Q1 2027 close is a company projection contingent on antitrust review. In a market this concentrated, that review is not a formality, and regulators have taken an interest in aggregates overlap before.
For contractors the question is narrower and more immediate: whether a consolidated supplier in your haul radius changes what you pay. Bidders on long-duration public work like the multi-year transmission and civil programs now in the market are the ones with the most exposure to that answer.
