Sg Micro Corp (300661.SZ) has submitted a listing application to the main board of the Hong Kong Stock Exchange, with China International Capital Corporation Hong Kong Securities Limited and Huatai Financial Holdings (Hong Kong) Limited acting as joint sponsors. This marks the company's second attempt to list in Hong Kong.
According to the prospectus, Sg Micro Corp is a comprehensive analog integrated circuit (IC) company that develops and sells high-performance analog ICs and sensors. These components perform functions such as sensing, amplification, conversion, and driving, serving as fundamental building blocks for all electronic systems. Data from Frost & Sullivan indicates that based on 2025 revenue, the company ranked first among domestic firms in China's analog IC market and eighth globally, capturing a 1.8% market share.
To date, the company offers over 6,800 analog IC and sensor products across 38 categories. Its products are not only core components in end markets like industrial, networking, and consumer electronics but are also increasingly applied in electric vehicles, data centers, robotics, renewable energy, and next-generation consumer devices.
Specifically, Sg Micro provides a broad and differentiated portfolio of general-purpose and application-optimized analog products, spanning two main domains: signal chain and power management, which form the dual pillars of its product matrix. Signal chain ICs help electronic devices interpret the physical world. The company's signal chain products capture, condition, and amplify signals from the physical world, converting them into high-precision digital signals while maintaining signal integrity from data acquisition to final output, which is crucial for applications requiring precise measurement, low noise, and minimal error.
Power management ICs control how energy is delivered within electronic devices. They determine the power allocated to different components, convert electricity to required voltage levels, and safely distribute power throughout the system while protecting against issues like power surges or abnormal current flow.
The company's customers primarily include distributors and direct sales clients. During 2023, 2024, and 2025, revenue from the top five customers accounted for 37.3%, 35.6%, and 33.1% of total revenue, respectively. Supplier concentration is relatively high, with key suppliers being wafer foundries and packaging and testing service providers. Purchases from the top five suppliers represented 92.4%, 92.3%, and 91.0% of total procurement amounts in 2023, 2024, and 2025, respectively.
Financial data shows revenue of approximately RMB 2.616 billion, RMB 3.347 billion, and RMB 3.898 billion for 2023, 2024, and 2025. Net profit for the same periods was approximately RMB 270 million, RMB 491 million, and RMB 534 million. Gross profit margins were 44.9%, 47.2%, and 46.2%, respectively.

From 2025 to 2029, the CAGR is projected to be 9.2%, reaching a market size of RMB 7.7 trillion by 2030. Integrated circuits constitute the largest segment, accounting for 88.1% of the total market.
Driven by rapid development in industrial and energy, automotive, networking and computing, and consumer electronics sectors, the global analog IC market grew from RMB 478.1 billion in 2021 to RMB 617.9 billion in 2025. Looking ahead, the proliferation of AI applications, advanced driver-assistance systems, and new energy vehicles is expected to drive growth, with the global analog IC market projected to reach RMB 927 billion by 2030.
As one of the largest consumers of analog ICs globally, China's market size increased significantly from RMB 158 billion in 2021 to RMB 218.4 billion in 2025, and is forecasted to reach RMB 389.4 billion by 2030. The signal chain IC segment is expected to maintain rapid growth due to industrial automation, new energy vehicles, and embodied intelligence, with its market size rising from RMB 57.1 billion in 2021 to RMB 79.3 billion in 2025, and projected to reach RMB 133 billion by 2030. China's power management IC market grew from RMB 99.9 billion in 2021 to RMB 139 billion in 2025, and is anticipated to strengthen further, reaching RMB 256.4 billion by 2030, driven by demand from AI infrastructure, new energy vehicle power systems, and smart devices.
Downstream, China's analog IC market shows varied growth trends across major application areas. The automotive sector is expected to be the fastest-growing segment, while networking and computing remain the largest downstream market. Industrial and energy applications continue to expand, with consumer electronics providing a solid demand base.
Both the global and Chinese analog IC markets maintain relatively stable and fragmented competitive landscapes. In 2025, the top eight companies collectively held a 37.3% share of China's analog IC market, with Sg Micro ranking first among Chinese firms and eighth globally. In the global analog IC market, the company ranked within the top fifteen.
The company's board will consist of seven directors, including two executive directors, two non-executive directors, and three independent non-executive directors. Directors serve three-year terms and are eligible for re-election.
