The Star has undergone a significant leadership change since the lifeline investment by Bally’s Corp and Investment Holdings last year, with Bally’s now holding 38 percent of The Star’s issued capital and Investment Holdings owning 23 percent.
In early March, however, the group still flagged its ability to continue as a going concern, after booking a AU$109.7 million ($77.44 million) fiscal half year loss for the period ending December 31st, 2025.
The Australian gaming operator recently flew out top executives from potential investor WhiteHawk Capital to visit its casinos, as it attempts to secure a refinancing package before the end of this month.
The group is also aiming to drastically cut costs by closing its corporate office, cutting jobs and shifting responsibilities.
In its recently released results, Bally’s Corp highlighted its ‘proven track record of revitalizing underperforming businesses’, noting it would ‘lend its expertise to Star and contribute to its successful turnaround’.
