ESR has secured investment from the CITIC Securities One-Belt-One-Road (CSOBOR) Fund ahead of its initial public offering.

The US$12bn (鈧10.3bn) manager backed by private equity firm Warburg Pincus, said CSOBOR鈥檚 investment will be used to fuel its rapid platform expansion in China and across the Asia-Pacific region.

No financial details were disclosed.

CSOBOR is a private equity investment fund of CLSA, Asia鈥檚 capital markets and investment group and a subsidiary of Chinese investment bank CITIC Securities.

Rui Zhao, a managing director at CSOBOR Fund, said: 鈥淐LSA investment and resources will assist the company to expand its business into Southeast Asia and identify fund-level investors in China.鈥

CSOBOR鈥檚 investment comes after ESR secured pre-IPO investment of US$306m from a subsidiary of the leading Chinese e-commerce player, JD.com, last month.

Also, early last year, a group of Chinese investors made up of GF Investments, Huarong International, Huarong Rongde, SPDB International, China Everbright, Everbright Securities and CMBC International backed ESR with U$300m ahead of the listing.

The timeline of the initial public offering is currently unknown.

Jeffrey Shen and Stuart Gibson, Co-CEOs of ESR, said: 鈥淭he investment from CLSA鈥檚 CSOBOR Fund into ESR is a tremendous endorsement of our capabilities and success.

鈥淭he funding will help ESR strengthen its market-leading position and accelerate the growth of its pan-Asia platform, creating greater, sustained value for both our investors and customers.鈥

ESR was formed in 2016 as a result of a merger between e-Shang and Redwood in January last year.
