Maider Medical Industry Equipment Co., Ltd., CHISON Medical Technologies Co., Ltd., Luoyang Jalon Micro-nano New Materials Co., Ltd. and Primeton Information Technologies, Inc. will be listed on the Shanghai Stock Exchange's sci-tech innovation board, commonly known as the STAR market, the China Securities Regulatory Commission said in a statement.

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.
