Citi's positive analyst rating for GREEN TEA GROUP is based on the observation that both new and existing stores have similar operating profit margins, indicating that the expansion of new stores is not negatively impacting profitability. The company is expected to achieve significant profit and sales growth by 2026, with a recovery in China's leisure dining industry supporting this outlook. Citi has raised its profit forecasts for the company, reflecting better-than-expected performance, and has increased the target price while maintaining a 'Buy/High Risk' rating.
