Chang Guang Chenxin, a leading Chinese developer of high-end image sensors with 14 years of expertise based in Changchun, has recently received approval from the Hong Kong Stock Exchange for its main board listing. Joint sponsors are CITIC Securities and Guotai Haitong, further strengthening the presence of domestic high-end CMOS manufacturers in the capital market.
Founded in 2012 by Dr. Wang Xinyang, an overseas talent introduced by the "Hundred Talents Program" of Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, the company built its technology foundation on the institute’s R&D strength. Instead of competing in the crowded consumer-grade market, it focuses on high-precision sectors including industrial imaging and scientific imaging.
The company’s technology ranks among the world’s top tier, with breakthroughs in 11 core proprietary technologies such as global shutter pixels, HDR pixels, and 3D wafer stacking. In 2015, it launched the world’s first BSI sCMOS image sensor, filling a critical domestic technology gap.
Based on 2024 revenue, Chang Guang Chenxin ranks third globally in the industrial imaging CMOS market with a 15.2% share, and also third in the global scientific imaging CMOS market with a 16.3% share, achieving major domestic breakthroughs in high-end segments.
The company has delivered steady and strong growth. From 2023 to 2025, revenue reached 605 million yuan, 673 million yuan, and 857 million yuan respectively. Net profit rose to 293 million yuan in 2025, with a gross margin of 66.9% and an adjusted net profit margin of 43.1%, showing exceptional profitability.
After previously pursuing a Sci-Tech Innovation Board listing, the company shifted to Hong Kong. Proceeds from the IPO will be used for R&D center construction, packaging and testing capacity expansion, and overseas market expansion. Before listing, it received investment from Hillhouse, SDIC Venture, SMIC Juyuan and other institutions, with a post-investment valuation of 10 billion yuan in 2022.
Dr. Wang Xinyang and his wife Zhang Yanxia hold a combined 49.53% stake, while Top Optronics and Lingyun Guanggu hold 25.56% and 10.22% respectively, supporting strong R&D and industrial advantages.
ICgoodFind：Chang Guang Chenxin’s Hong Kong listing highlights its leadership in high-end CMOS for industrial and scientific imaging, driving breakthroughs in domestic high-end image sensor chips.
