CRH Buys Arcosa for US$8.5bn in Its Biggest-Ever Deal

Cement Roadstone Holdings has agreed the biggest acquisition in its history. The Irish-American building materials group is buying Dallas-based Arcosa for US$8.5bn in an all-cash deal, paying US$150 a share to tighten its hold on the North American aggregates market.

Barely 18 months into the top job, CEO Jim Mintern treats the purchase as a statement of intent.

The deal, he says, "advances our strategy to build an aggregates-led, connected portfolio", the model CRH has staked its future on.

Why Arcosa is worth US$8.5bn

CRH has had hundreds of bolt-on deals under former chief Albert Manifold but none has stretched that acquisition machine like this one.

The prize is a serious slab of American aggregates, with Arcosa's Construction Products arm running 109 quarries and yards, nine asphalt plants and shipping around 35 million tons last year.

Fold that into CRH and the combined group produces more than 265 million tons of aggregates a year, the biggest producer on the continent. 

At US$8.5bn, the deal values Arcosa at 11.5 times its forecast core earnings and hands shareholders a 25% premium, though CRH expects to recoup US$175m of that through annual cost savings by year three.

"This strategic acquisition reinforces our position as the number one infrastructure player in North America and advances our strategy to build an aggregates-led, connected portfolio," says Jim.

CRH's defining bet

Jim took the top job at the start of 2025, inheriting a strategy of relentless dealmaking and a fresh US stock listing built to put CRH closer to American investors and American contracts.

Arcosa is the boldest acquisition in CRH's history and the clearest signal the group means to keep rolling up a fragmented market rather than sit back and harvest what it already owns.

The sale is "a powerful validation of the work we've done in recent years to grow in attractive markets, simplify our portfolio, reduce cyclicality and build a more resilient business", says Acrosa President and CEO Antonio Carrillo.

He expects CRH's scale to serve Arcosa's staff and customers once the deal closes, which CRH pencils in for the first quarter of 2027, subject to shareholder and regulatory approval.

A fresh wave of sector dealmaking

Across building materials and chemicals, the biggest players are using acquisitions to strip out cost and ride the US construction cycle, with American manufacturer Olin's pursuit of Huntsman the latest parallel.

For CRH, the US$8.5bn deal still needs Arcosa's shareholders and the regulators to agree. 

If it lands as planned in early 2027, Jim will have turned his predecessor's playbook into the largest bet CRH has ever made.
