CRH Just Closed an $8.5 Billion Deal — and Arcosa Stock Vanished From the Market

CRH has completed its $8.5 billion acquisition of Arcosa — and Arcosa stock is gone from the market. The building-materials giant closed the deal on Friday, October 23, 2026, paid Arcosa shareholders $150.00 a share in cash, and immediately triggered Arcosa's delisting and its removal from the S&P SmallCap 600. It is one of the biggest U.S. infrastructure deals to close this earnings season.

What happened, in one answer

CRH (NYSE: CRH) announced on October 23, 2026 that it had completed its acquisition of Arcosa, Inc., a leading U.S. provider of aggregates and critical infrastructure products, for a total enterprise value of approximately $8.5 billion. The agreement was first announced on June 22, 2026, Arcosa shareholders approved it at a special meeting on September 4, and trading in Arcosa shares was halted before the open on October 23 as the merger closed.

The key facts

Deal value: approximately $8.5 billion enterprise value
What Arcosa holders got: $150.00 per share in cash; their shares were cancelled at closing
Index change: Howard Hughes Holdings (HHH) will replace Arcosa in the S&P SmallCap 600, effective before the open on Wednesday, October 28, 2026
CRH's close on the day: $84.89, down $1.54 (-1.78%), with a market value of roughly $56.9 billion
Next catalyst: CRH will give updated full-year 2026 guidance reflecting the deal with its third-quarter results on October 29

Why this deal is blowing up

First, the size. At $8.5 billion, this is not a bolt-on — it reshapes CRH's U.S. footprint in one move. CRH called the deal "highly complementary" to its aggregates-led, connected portfolio strategy, saying it reinforces the company's position as the leader in U.S. and global aggregates and increases its exposure to demand from major road, water, energy and data projects across the country.

Second, the assets. Arcosa brings high-quality aggregates operations plus attractive positions in the growing U.S. energy transmission market — the poles, structures and related products that carry new power lines. That is exactly the spending stream tied to grid upgrades and data-center power demand, which is why traders and infrastructure investors spent the day talking about the close rather than the original announcement.

Third, the market plumbing happened instantly. Arcosa asked the exchanges to suspend trading and delist its shares, said it would file to deregister its stock, repaid about $450.1 million outstanding under its old credit agreement, and saw its board and officers replaced at closing, according to its closing filings. S&P Dow Jones Indices moved the same day to fill the SmallCap 600 vacancy with Howard Hughes Holdings — so index funds holding Arcosa now have a dated, mechanical trade to make before October 28.

What CRH's CEO said

"Arcosa is an excellent strategic fit for CRH and fully aligns with our growth ambitions," CRH CEO Jim Mintern said in the completion release. "With high-quality aggregates assets and attractive positions in the growing U.S. energy transmission market, the acquisition strengthens our connected portfolio and reinforces our position as the #1 infrastructure player in North America."

CRH describes itself as the leading provider of building materials critical to modernizing infrastructure, with a team of about 83,000 people across 4,000 locations, and it is a member of the S&P 500 Index.

Why CRH stock fell on a closing day

CRH shares slipped 1.78% to $84.89 on October 23, even as the company closed its biggest recent deal. That kind of move is common on large acquisitions: the price Arcosa holders receive is fixed, so there is no closing-day surprise left to trade on the target, while the buyer takes on the integration work and the financing. Closing filings summarized in market coverage indicate the merger consideration was funded with proceeds from a $3.25 billion bridge facility and a $2.5 billion term loan facility, together with cash on hand — leverage investors will now weigh against the earnings Arcosa adds.

What's next

The story now has two hard dates. On October 28, Howard Hughes Holdings joins the S&P SmallCap 600 in Arcosa's place. On October 29, CRH reports third-quarter results and — crucially — updated full-year 2026 guidance that reflects Arcosa. That guidance is the first official number investors will get for what the combined company earns, what the deal does to leverage, and how quickly management expects the aggregates and energy-transmission assets to contribute. Until then, the $8.5 billion price tag is known; the payoff is what October 29 has to prove.
