North America's Largest Cement Spin-Off Surges Over 2 Trillion Won in Just One Day

North American building materials firm Amrize AG (NYSE: AMRZ) jumped 5.07% to close at $58.41 on the New York Stock Exchange. Trading volume topped 1.93 million shares, well above its average, and its market capitalization climbed to roughly $32.2 billion (about KRW 45 trillion). In a single day, its market cap grew by approximately $1.7 billion (around KRW 2 trillion).

On Wall Street, 12 brokerages maintain a “Buy” consensus on Amrize, with an average 12-month price target of $60.33, suggesting single-digit upside from current levels. The next earnings report is slated for February 17, drawing market attention to the company’s first full-year guidance since its complete spin-off from Holcim.

Amrize was carved out of Swiss cement giant Holcim’s North American division and listed in June 2025. It has since become the largest cement supplier in North America and a leading producer of aggregates and commercial roofing materials. Its 2024 revenue is estimated at around $11.7 billion (about KRW 12.5 trillion), making it a bellwether for infrastructure, housing, and data center investment in the U.S. and Canada.
