ChangXin Technology said the overallotment option tied to its initial public offering and STAR Market listing has been fully exercised, resulting in an additional issuance of 1.003 billion shares. The move increased the company’s total share capital to 67.884 billion shares. During the overallotment exercise period, the stock traded above its issue price of RMB 8.66 per share. As a result, CICC, acting as the authorized joint lead underwriter, did not use the proceeds from the overallotment to buy shares in the secondary market through competitive trading.
