22 companies filed for Hong Kong Stock Exchange listings in one week: AI semiconductor supply chain dominates the headlines, with star companies like Avita among them.

Mars Finance reported on July 5th that, according to disclosures by the Hong Kong Stock Exchange (HKEX), from June 29th to July 4th, a total of 22 companies submitted IPO prospectuses to the HKEX, including Shengwei Times, Liante Technology, Shengjing Network, Yangtuo Holdings Inc., Longxun Semiconductor, Haote Energy Saving, Tongao Testing, Daotong Technology, Keli Limited, Avita, Wubo Technology, Jiaxuan Intelligent, Oulin Biotechnology, Yuanhai International, Silicon-based Flow, Huaneng Design Institute, Senyi Intelligent, Joint Stock Company National Company Kazakhstan Temir Zholy, Liding Semiconductor, Jingze Biotechnology, Hongxinyu, and Jingwang Electronics. Among the 22 companies that submitted their prospectuses, 5 A-share listed companies simultaneously applied to the HKEX, triggering a new wave of "A+H" dual listings. Among them, Jingwang Electronics leads with a market capitalization of 70.949 billion yuan. This leading PCB manufacturer's revenue exceeded 10 billion yuan each year from 2023 to 2025, with a compound annual growth rate of 46% in profits over three years. The company has significant related-party transactions with Luxshare Precision, and the demand for PCBs driven by AI computing power is its core growth logic. Liante Technology is a leading optical module manufacturer from Wuhan and one of the few global suppliers with vertical integration capabilities for 800G/1.6T optical modules, with a latest market capitalization of 38.764 billion yuan. Daotong Technology, Orin Biotech, and Longxun Semiconductor are from the automotive intelligent diagnostics, human vaccines, and high-speed video chips sub-sectors, respectively, and are all star companies on the Science and Technology Innovation Board, with latest market capitalizations of 17.418 billion yuan, 17.319 billion yuan, and 11.562 billion yuan, respectively. All three companies appeared as "spin-off subsidiaries." Wubo Technology is a smart logistics supply chain service provider for ferrous bulk commodities under Yankuang Energy. Based on 2025 Gross Transaction Value (GTV), it is the largest smart logistics platform in China's steel and metallurgical industry. Tongao Testing, spun off from the Hong Kong-listed Anton Oilfield Services, ranks second among professional testing institutions in China's oil and gas industry's integrated TIC solutions market and is a leading independent oil and gas testing TIC service provider. Liding Semiconductor, backed by global PCB leader Zhen Ding-KY, mainly produces high-end IC substrates such as FCBGA and FCCSP. Based on 2025 revenue, it ranks third among IC substrate manufacturers in mainland China. Of the 22 companies, AI and semiconductor-related companies account for nearly half. From upstream chip design (Longxun Semiconductor), memory (Hongxinyu), and IC substrates (Liding Semiconductor), to midstream optical modules (Liantech) and PCBs (Jingwang Electronics), and then to AI infrastructure (Silicon-based Flow), the entire AI industry chain is represented. Among them, Silicon-based Flow has applied for listing under the Hong Kong Stock Exchange's Chapter 18C Special Technology Companies Rules. Established only 34 months ago, its valuation has increased more than 33 times in three years, reaching a latest valuation of 7.74 billion yuan. Alibaba, Huawei, Meituan, and Innovation Works are all shareholders. This time, it aims to become the first "AI Token Factory" listed in Hong Kong. Hongxinyu's revenue exceeded US$1 billion and net profit exceeded US$500 million in the first four months of 2026, representing a more than 30-fold increase in net profit. Based on 2025 revenue, it will be the fifth largest independent memory manufacturer globally and the second largest in mainland China. Multiple high-profile targets from various sectors are simultaneously emerging. In the new energy sector, Avita is a rare Hong Kong IPO target in the domestic high-end new energy vehicle field. The company is jointly established by Changan Automobile, CATL, and Huawei. It achieved operating revenue of 5.645 billion yuan, 15.2 billion yuan, and 25.6 billion yuan in 2023, 2024, and 2025 respectively, achieving a leapfrog growth in revenue over three years; however, its losses are also increasing, accumulating to approximately 11.2 billion yuan over three years. In the AI healthcare field, Senyi Intelligent, as China's largest provider of intelligent hospital healthcare solutions, has served over 800 hospitals. Its shareholders include Tencent, Sequoia Capital, and IDG. Meanwhile, Kazakhstan Railways, controlled by Kazakhstan's sovereign wealth fund, is a state-owned transportation and logistics giant operating a vital land transport corridor connecting Central Asia with China and Europe. Its IPO in Hong Kong, as a key infrastructure company in a Belt and Road Initiative country, has attracted widespread market attention. (Science and Technology Treasure News)
