Fortior Technology (SHA:688279, HKG:1304) said its overallotment option was fully exercised, resulting in the issuance of 2.8 million H-shares at HK$120.5 each, raising about HK$326.3 million in additional net proceeds, according to a Thursday Hong Kong bourse filing.

The shares represent 15% of the initial offer size before the option exercise and will be used to cover over-allocations in the international tranche.

Trading of the new shares is set to begin on July 29.

Fortior plans to use the proceeds on a pro-rata basis in line with its IPO prospectus.
