Didi’s shares closed down by 44% to $1.89 on Friday amid reports that the company’s likely Hong Kong listing faces a delay due to uncertainty over regulatory approval, Bloomberg reported, citing people familiar with the matter. The ride-hailing giant has suspended work with its financial advisers after being told by China’s cyberspace regulator that its recent filings failed to meet the requirements on data security compliance, the report said. In December, Didi announced plans to sell shares in Hong Kong months after Beijing launched an investigation into the company following its US IPO. [Bloomberg]
