Trillion Trophy Asia has completed their protracted takeover of Sky Bet Championship club Birmingham.
The buyout comes 16 months after the group were given a two-year exclusivity period to purchase the club.
Shares in Blues' parent company Birmingham International Holdings Limited resumed trading on the Hong Kong Stock Exchange on Monday.
TTA, who are controlled by Hong Kong businessman Paul Suen, now hold approximately 50.64 per cent of BIHL's shares.
Birmingham confirmed: "The club's parent company, Birmingham International Holdings Limited (BIHL), has resumed trading on the Hong Kong Stock Exchange and is now in the expert hands of Trillion Trophy Asia Limited (TTA).
"It means that, as a club, we have new owners - and we welcome all at TTA into the Blues family and we look forward to exciting times ahead at St. Andrew's under their guidance and with their backing."
TTA's buyout ends Carson Yeung's seven-year ownership of the club which saw them win the League Cup in 2011 but also relegated from the Premier League the same year.
Yeung was jailed in 2014 having been found guilty of money laundering.
TTA had been offering financial backing to Blues for some time and little is likely to change at the St Andrew's club with the group remaining as owners for at least two years.
Birmingham are sixth in the Championship and host Rotherham on Tuesday.
