World’s Biggest Listing Gets Bigger After CATL Exercises Option

Contemporary Amperex Technology Co. Ltd. has raised HK$41 billion ($5.2 billion) for its Hong Kong share sale after arrangers of the deal exercised the so-called greenshoe option to increase the offering, making the world’s biggest listing this year even bigger.

The Chinese electric-vehicle battery giant, commonly known as CATL, is issuing 20.3 million additional shares, representing about 15% of total shares issued for the listing after the upsize option, according to a filing it made to the Hong Kong exchange late Tuesday. That increases the deal size from HK$35.7 billion.
