Mitsui Kinzoku shares surged to a record 30,000 yen on strong fiscal 2025 guidance, with 10% gains driving it to become a top performer on the Nikkei 225. The Japanese non-ferrous metals specialist raised its annual operating income forecast to 117.0 billion yen ($760 million), up from 78 billion yen, citing robust demand for its copper foil used in AI server production. Copper prices skyrocketed and a weaker yen boosted overseas margins, while expanded production capacity and favorable inventory trends further fueled optimism.

For nine months to December, net sales rose 3.1% to 542.2 billion yen, though net profit dipped 5.9% due to a one-off loss from selling its Mitsui Kinzoku ACT unit. Investors are betting on sustained demand for critical metals in AI infrastructure, positioning Mitsui Kinzoku as a key beneficiary of the tech-driven metals boom.
