On June 27, 2026, Martin Marietta agreed to acquire all equity interests in Lhoist North America from LNA Holding for $13.5 billion, consisting of $7 billion in cash and 10,953,543 newly issued Martin Marietta shares valued at $6.5 billion.

Briefs marked “Written later” were written in November 2026 for filings that were by then more than three weeks old, so months before mid-October 2026 hold a selection: every material 8-K of the past year for the 100 largest companies we cover and the last 15 important 8-Ks of every other one. Briefs the number check holds back are not shown or counted. Also: the last 45 days, briefs by company, A–Z and the live SEC filings wire.
