Record-Setting Terms

CXMT priced its IPO at 8.66 yuan per share, raising 57.9 billion yuan ($8.5 billion) from the sale of nearly 6.7 billion shares. If a 15 percent overallotment option is fully exercised, the offering could expand to 66.6 billion yuan ($9.8 billion). The deal gives CXMT an implied valuation of roughly 579 billion yuan ($85.2 billion), making it the largest A-share IPO by a Chinese chip company, surpassing Semiconductor Manufacturing International Corporation's 53.2 billion yuan listing in 2020.bloomberg+3
