oaring demand from AI data centers has benefited suppliers of optical connections across the globe. Among them is RoboTechnik Intelligent Technology, which supplies assembly and testing equipment for optical systems to companies such as U.S. semiconductor giant Broadcom. While its Shenzhen-listed shares have surged 340% the past year, the company filed for a Hong Kong dual listing on Wednesday.

RoboTechnik did not disclose details of its planned dual listing in the filing. The Suzhou-based company joins a growing list of mainland Chinese companies tapping capital in Hong Kong, drawn by deeper liquidity, broader investor base and a more transparent market pricing mechanism.

RoboTechnik is founded by Dai Jun, who serves as the company’s chairman and CEO. The 52-year-old owns a roughly 17% stake. Forbes estimates Dai is worth $2.4 billion based on Friday’s closing price of 589.98 yuan.

A trained engineer, Dai started RoboTechnik in 2011 to develop manufacturing equipment for photovoltaic cells, which convert sunlight into electricity on solar panels. He took the company public on the Shenzhen stock exchange’s tech-focused ChiNext board in a 431 million yuan ($63.6 million) IPO in 2019.
