U.S. Fire and Safety Stocks Surge… Market Cap Increases by 1.6 Trillion Won in One Day

On March 23, API Group Corporation (APG) closed on the New York Stock Exchange at $41.87, up 6.0%. Its market capitalization swelled to about $18 billion (roughly ₩24 trillion), rising by some $1.1 billion (about ₩1.6 trillion) in a single day. Trading volume reached approximately 3.22 million shares, reflecting strong investor demand and fueling the stock’s advance.

Recently, the company announced the acquisition of CertaSite, a fire and life safety services provider in the U.S. Midwest, targeting completion in the first quarter of 2026 as part of its expansion strategy. Earlier in 2025, API Group delivered consecutive quarterly record results and raised its full-year guidance, underscoring both operational strength and the impact of its acquisitions.

API Group is an industrial services firm focused on North America and Europe, offering fire protection systems, life safety, security, and specialized infrastructure maintenance services. In 2022, it completed the roughly $3.1 billion (≈₩4 trillion) acquisition of Chubb Fire & Security, elevating it to one of the world’s largest life safety service platforms, and has since expanded its market share through further acquisitions.
