Five Chinese mainland technology and advanced manufacturing companies have simultaneously launched initial public offerings on Hong Kong stock exchange on Tuesday, seeking to raise up to HK$44.1 billion ($5.6 billion) in one of the market's biggest single-day fundraising pushes this year.

The companies — Luxshare Precision Industry Co Ltd, Chaozhou Three-Circle Group Co Ltd, Nexchip Semiconductor Corp, Guangdong Dtech Technology Co Ltd, and robotics maker ROKAE — span industries including consumer electronics, advanced ceramic materials, semiconductor manufacturing, printed circuit board tooling and industrial robotics.

Luxshare Precision, a key supplier to Apple, accounts for more than half of the planned fundraising, targeting up to HK$24.27 billion through the sale of 383.5 million shares.

The company is expected to price the offering on July 8 and begin trading on July 10. It is seeking to establish a dual A+H listing as it expands its international financing channels.
