Summit Materials (ISIN US86614U1007) was acquired by Quikrete for an enterprise value of USD 11.5 billion in February 2025, according to Global Cement. The transaction changed the investment case from a listed construction-materials stock to a privately held operating business.

Quikrete paid USD 52.50 per share

According to Multiples, Quikrete agreed to pay USD 52.50 in cash for each Summit Materials share. The stated enterprise value was USD 11.5 billion, including debt, and the offer represented a 29 percent premium to Summit's unaffected share price and a 36 percent premium to its unaffected 90-day volume-weighted average price.

The transaction closed on February 10, 2025, and Summit became a privately held subsidiary of Quikrete, according to Multiples. Its New York Stock Exchange listing ended with the closing, so the former SUM security does not represent an ongoing public-market quotation.

What the deal means for Summit Materials stock

The key figure for former shareholders was the USD 52.50 cash consideration rather than a continuing share-price target. The 29 percent premium to the unaffected price and the 36 percent premium to the 90-day volume-weighted average price quantified the value transfer at signing.

Summit Materials had built a vertically integrated materials platform before the transaction. Multiples describes reported annual operating volumes of 17.5 million tons of aggregates, 1.0 million tons of cement, 1.2 million cubic yards of ready-mixed concrete and 3.9 million tons of asphalt paving mix. Those figures explain why Quikrete pursued vertical integration across construction materials and infrastructure markets.

Private ownership defines the current status

Summit Materials continues as an operating business serving residential, commercial and public-infrastructure customers across the United States and British Columbia, Canada. For former public-market investors, the relevant documented outcome is the USD 52.50 cash transaction completed on February 10, 2025, rather than a live SUM quotation.
