BEIJING — China's securities regulator has approved four companies' initial public offerings (IPOs) on the science and technology innovation board.

Bingo Software Co Ltd, Focuslight Technologies Inc, Primarius Technologies Co, Ltd and Beijing Chunlizhengda Medical Instruments Co Ltd will be listed on the Shanghai Stock Exchange's sci-tech innovation board, commonly known as the STAR market, according to the China Securities Regulatory Commission.

The companies and their underwriters will confirm the dates of the IPO and publish prospectuses following discussions with the stock exchange.

The STAR market, inaugurated in June 2019 and designed to support companies in the high-tech and strategic emerging sectors, has eased its listing criteria but adopted higher requirements for information disclosure.
