6 Trillion Won Nuclear Power Beneficiary Stocks Gain 360 Billion Won in Just One Day

Mirion Technologies (Nasdaq: MIR) closed at $18.60 on the New York Stock Exchange on the 17th, up 5.38%. Trading volume exceeded 3.64 million shares, pushing its market capitalization to about $4.5 billion—approximately KRW 6.4 trillion—adding roughly $260 million (KRW 360 billion) in a single day.

In its first-quarter results reported in April, the company beat expectations with revenue of $257.6 million, a 27.5% increase year-over-year, and adjusted EBITDA of $54.3 million. Despite these strong numbers, the share price had recently fallen to a 52-week low of $16.71. At the recent Citi Global Industrial Technology Conference, Mirion highlighted growth in its nuclear segment, initiatives in artificial intelligence and data-center applications, and set a target of achieving a 30% EBITDA margin by 2028.

Mirion Technologies provides radiation-detection, measurement and monitoring solutions to nuclear power plants, hospitals, defense agencies and research institutions, making it a leading beneficiary of the global nuclear restart trend and the expansion of cancer-treatment services. After going public in 2021 through a SPAC merger with a Goldman Sachs entity, Mirion has strengthened its nuclear offering by acquiring Paragon Energy Solutions and CerTec, adding equipment and regulatory-compliance software to increase its nuclear-related revenue share.
