BEIJING — China's securities regulator has given the nod to the registration-based initial public offering (IPO) of four companies on the science and technology innovation board.

Balance Medical Co Ltd, a Beijing-based medical product manufacturer; Jiangsu Eazytec Co Ltd, a cloud-computing service provider; Jiangsu Bioperfectus Technologies Co Ltd, a biotech firm and Jiangsu Beiren Robot System Co Ltd, a smart manufacturing solution provider, 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.

It did not specify the total amount of funds to be raised.

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

The STAR market, inaugurated in June and designed to focus on companies in the high-tech and strategic emerging sectors, eases the listing criteria but adopts higher requirements for information disclosure.
