Guangdong Huayan Robotics Co has confidentially filed for a Hong Kong initial public offering that could raise more than $200 million, according to people familiar with the matter.

The Shenzhen-based company may go public in the coming months, the people said, asking not to be identified because the information is not public. Deliberations are ongoing, and the size and timing of the deal may change.

Huayan Robotics did not respond to a request for comment.

The company, previously known as Han’s Robot, specializes in making products known as collaborative robots, or cobots, that can be programmed to carry out tasks ranging from tightening screws to welding and the polishing of surfaces.

Confidential filings in Hong Kong have typically been reserved for firms listed on another exchange, but they have become more common after the city began allowing companies in the technology and biotechnology space to also confidentially submit applications.
