Nio moved a step closer to a secondary listing in Singapore on Thursday, saying that it has received the permit to list its class A ordinary shares on the city’s main board by way of introduction. A listing document will be issued by the end of this month, the company added, a move it hopes will boost its business in the region, according to a Reuters report published on Feb. 28. The potential listing comes after the electric vehicle maker was added to a list of Chinese firms at risk of delisting from US stock exchanges by the US securities regulator on Thursday.
