Starbucks has invited Carlyle, EQT, HongShan, and Boyu Capital to submit final bids for a controlling stake in its China business, Reuters reported. Bids are due early October, with a deal possible by month-end. The unit could be valued up to $5 billion as Starbucks loses ground to Luckin and Cotti. Shares rose 0.3% in premarket; YTD stock is down 9.2%.
