Cao Cao Mobility, a ride-hailing subsidiary of Chinese automaker Geely, is pushing ahead with plans to file its prospectus as early as April for an initial public offering in Hong Kong, according to a Tuesday report by Bloomberg. The Didi challenger has hired investment banks including ABC International Holdings Ltd., Bank of America Corp, and Huatai International for the public share sale, which could happen within the next year and raise several hundred million dollars, sources told Bloomberg. The carmaker on Oct. 31 also said it was looking to spin off its premium electric vehicle brand Zeekr as a public firm. [Bloomberg]
