OneRobotics (Shenzhen) (HKG:6600) said its underwriters partially exercised the overallotment option of its Hong Kong listing, and the stabilization period of its initial public offering ended on Thursday, Jan. 22, according to a same-day filing with the Hong Kong bourse.

Shares of the home robotics systems provider were up over 3% in morning trade Friday.

The firm will issue over 3.13 million H shares at HK$73.80 apiece for additional net proceeds of HK$225.5 million.

The overallotment option was exercised after an equal number of shares were over-allocated in the international portion of the IPO.

Meanwhile, the IPO's underwriters purchased 1.14 million H shares from the open market during the stabilization period and sold 944,000 H shares.

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.
