Arcosa, Inc. (NYSE:ACA) shareholders approved the proposed acquisition by CRH plc (NYSE:CRH) on September 4. The merger agreement received 39,595,867 votes in favor, compared with 66,113 against and 16,786 abstentions. Approximately 39.7 million shares, representing 80.8% of shares outstanding as of the record date, were present or represented by proxy.
The vote satisfies a major condition for the all-cash transaction. CRH plc (NYSE:CRH) agreed to pay $150 per share, valuing Arcosa, Inc. (NYSE:ACA) at an enterprise value of approximately $8.5 billion. The companies continue to expect a first-quarter 2027 closing, subject to required regulatory approvals and other customary conditions.
CRH plc (NYSE:CRH) described the valuation as 11.5 times estimated 2026 adjusted EBITDA, a company-defined non-GAAP measure, including $175 million of targeted annual run-rate cost synergies expected by year three. CRH plc (NYSE:CRH) defines adjusted EBITDA as earnings from continuing operations before interest, taxes, depreciation, depletion and amortization, with exclusions for impairments, divestitures and investments, equity-method results, substantial acquisition costs and specified pension items.
The result removes the principal seller-side approval risk. The merger no longer depends on another shareholder meeting, and support was decisive among the shares represented. Financing appears less exposed than regulatory clearance: CRH plc (NYSE:CRH) plans to use available cash and committed debt financing, while completion is not subject to a financing condition.
The strategic rationale is tangible. Arcosa, Inc. (NYSE:ACA) would add 109 quarries and yards, nine asphalt plants, 19 terminals and approximately 35 million tons of 2025 aggregates shipments. CRH plc (NYSE:CRH) expects more than 265 million tons of combined annualized aggregates production. Arcosa, Inc. (NYSE:ACA) also brings engineered structures serving grid modernization, electrification and data-center construction.
