Contemporary Amperex Technology Co. Ltd. $300750.SZ, the world’s leading electric vehicle (EV) battery manufacturer, is preparing for a landmark equity offering in Hong Kong. Aiming to raise approximately $5 billion, the Shenzhen-listed Chinese conglomerate is in the final stages of planning a secondary listing that could mark the territory's largest equity sale in nearly four years. According to sources familiar with the matter, CATL is offering shares at a modest discount of under 10% relative to its domestic valuation—an unusually tight margin for a deal of this scale.
