In 2006, Warburg Pincus invested US$10 million. In 2007, Merrill Lynch, Deutsche Bank, and Warburg Pincus further invested a combined total of US$95 million. In 2008, Actis Capital led a US$65 million investment in 7 Days Inn, in which Warburg Pincus again participated. Despite losses amounting to ¥209.9 million (US$30.8 million) in 2008 and ¥9.3 million (US$1.4 million) in the first three quarters of 2009, it listed on the New York Stock Exchange in September 2009, issuing 10.1 million American Depositary Shares (representing 20.6% of the company) at US$11/share, raising a total of $111.1 million. CEO Zhang retained a 13.4% stake. 7 Days Inns' failure to turn a profit up to that point meant they were unable to make an offering of A shares in China.
In 2010, forty disgruntled workers held a protest outside 7 Days Inn's office in Shenzhen. The workers in question were employed by a subcontractor performing renovations on 7 Days Inn branches in the city, and alleged non-payment of wages.
