Korea Zinc, the world’s largest zinc smelter, announced a plan to repurchase shares worth over $2 billion to counter a hostile takeover attempt by South Korean investment firm MBK Partners. The buyback aims to secure an additional 15.5% stake alongside Bain Capital’s purchase of a 2.5% stake. Korea Zinc will repurchase shares 11% higher than MBK's offer. MBK Partners is aiming for a controlling stake of nearly 47%.
