Four companies are set to raise a combined HK$14.4 billion ($1.8 billion) in Hong Kong listings beginning trading on September 29. The largest offering comes from Robo Technik Intelligent Technology Co., seeking up to $660 million after its Shenzhen-listed shares surged 168% this year. The maker of automation equipment for solar-panel and silicon-photonics chip factories also has an upsize option of up to 15% of the base offering via Bloomberg Terminal.

Other participants in the market spree complete the batch of new listings, though specific details for the remaining issuers were not specified in the report. The activity highlights continued investor interest in Hong Kong's market despite global economic headwinds.
