CRH PLC received regulatory approval to acquire Ash Grove Cement Co. for $3.5 billion after agreeing to sell facilities in three states to satisfy Federal Trade Commission concerns.

The buyer, an Ireland-based construction company, agreed to divest a cement facility in Montana, sand and gravel plants in Nebraska, and limestone quarries and hot mix asphalt plants in Kansas.

CRH said no further regulatory approvals are outstanding.

The deal, which was announced in September 2017, is expected to close this month.
