Jinghe Ji Cheng is a high-tech enterprise specializing in the design, testing and packaging of integrated circuits, which was listed in science and technology innovation board on May 5, 2023. The initial public offerings of Beijing and Ji Cheng adopted the green shoe mechanism, granting CICC the option of over-allotment of no more than 65,438+05% of the initial issued shares, that is, 75,230,000 shares.

The green shoe mechanism means that the sponsor (lead underwriter) obtains a certain number of over-allotment options during the initial public offering of shares, and can buy the issuer's shares from the secondary market at the issue price for a period of time after the issuance, so as to stabilize the stock price and increase market liquidity. Therefore, Jinghe Integration fully exercised the green shoe mechanism during the exercise of the over-allotment option.
