HashKey (HKG:3887) said its underwriters partially exercised the overallotment option of its Hong Kong listing, and the stabilization period of its initial public offering ended on Sunday, Jan. 11, according to a Monday filing with the Hong Kong bourse.

The licensed digital asset platform provider will issue 892,400 shares at HK$6.68 apiece for additional net proceeds of HK$5.8 million.

The overallotment option was exercised after around 36.1 million shares were over-allocated in the international portion of the IPO.

A further 35.2 million shares were purchased from the open market during the stabilization period to meet the overallocation.

The number of shares held by the public after the exercise of the overallotment option complied with Hong Kong's listing requirements, the firm said.
