(Yicai Global) Sep. 3 -- China's Meituan Dianping has named five cornerstone investors for the online services platform's upcoming listing in Hong Kong with tech giant Tencent Holdings included in the list.

Other investors include Oppenheimer, Lansdowne, Darsana and Chengtong Fund Management, Yicai Global learned from sources close to the Beijing-based firm.  

Meituan is yet to reveal financing targets though sources value the firm at USD50 billion to USD55 billion post-floatation with at least USD4 billion raised, making it the third biggest IPO in the special administrative region this year.

Tencent is Meituan's largest stakeholder with a 20 percent share and is expected to subscribe to some USD400 million-worth of shares. The company made a strategic investment in Dianping worth some USD4 billion last October.

Fellow cornerstone investor Oppenheimer is a global investment firm that has previously subscribed to shares in major firms from China and abroad such as Tencent, Alibaba, JD.Com, Netflix, Facebook, TripAdvisor and iQIYI. Renowned UK investment fund Lansdowne shot to fame in 2012 when investing in local online supermarket Ocado.

Darsana is an investment fund that has held positions in several tech companies including Baidu, Facebook, Netflix and Booking for a long time. Set up by China's state-owned assets regulator, Chengtong Fund Management counts China Merchants Group, Sinopec, the China Petroleum and Chemical Corporation and China Mobile Communications Group among its shareholders.

Upon listing, Meituan will become the second beneficiary of new rules allowing Hong Kong listings for firms with weighted voting rights, which grant more power to certain shareholders like founders and high-ranking executives. Smartphone giant Xiaomi was the first to take advantage, raising USD4.7 billion in June.
