Martin Marietta has its approvals.

The Raleigh building materials company told the Securities and Exchange Commission on Wednesday afternoon that it has received all necessary regulatory approvals to buy Lhoist North America, and that it now expects to complete the purchase in the third quarter of 2026, subject to customary closing conditions. The agreement itself is six weeks old. Martin Marietta and LNA Holding SRL, a Belgian limited liability company, signed a Securities Sale Agreement on 27 June under which Martin Marietta acquires all of the outstanding equity in Lhoist North America for $13.5bn in cash and Martin Marietta shares.

The filing is one paragraph of news attached to a page of boilerplate, and what it leaves out is as clear as what it says.

What the document does not name

It does not name a regulator. Not one, in either the Item 8.01 text or the press release furnished with it. There is no agency, no statute, no docket, no date on which the final clearance landed, and no mention of whether any condition or divestiture was attached to any of the approvals. The company reports the result and stops.

That reticence is normal in an 8-K and it is worth stating plainly rather than filling in. A reader who wants to know whether the transaction was cleared with remedies cannot learn it here.

What Lhoist North America is

The business Martin Marietta is buying produces, distributes, markets and sells lime, dolomitic lime, limestone and dolomitic stone-based industrial minerals and products, and aggregates in North America. That description is the 8-K's own.

Martin Marietta already runs a Specialties business in high-purity magnesia and dolomitic lime, across a network the company puts at 29 states, Canada and the Bahamas. On completion, it says, it expects to become the nation's leading producer of lime and limestone solutions. That claim belongs to the company. No regulator named in the filing has made it, because no regulator is named in the filing.

The two dates that matter

27 June, when the agreement was signed and the price was set. 5 August, when the approvals were reported complete.

Between them sit the antitrust and sectoral reviews that a $13.5bn combination in industrial minerals attracts, and the document treats that entire period as a single sentence. The transaction is not closed. Martin Marietta expects the third quarter, which has eight weeks left in it.

The consideration is cash and stock together, and the filing does not break it into parts.

The document: Martin Marietta Materials Form 8-K, Item 8.01, and Exhibit 99.1 press release, filed 5 August 2026.
