China Micro Semicon(Shenzhen) Limited, the domestic leader in MCU unit shipments, is advancing its strategy to establish dual capital market platforms. According to a filing with the Hong Kong Stock Exchange on March 30, the company submitted an application for a main board listing, with China Securities (International) Corporate Finance Limited acting as the sole sponsor. The proceeds from the offering are intended to bolster research and development efforts and support global expansion. The company aims to solidify its advantages in the consumer electronics and smart home appliance markets while further expanding into higher value-added sectors such as industrial control and automotive electronics.
As a leading provider of smart control solutions in China, the company was among the earliest domestic enterprises to achieve independent R&D and design of MCUs. Its core business focuses on integrated circuit chip design and delivery, with MCUs as the central product. The product portfolio has expanded to include system-on-chip (SoC) and application-specific integrated circuit (ASIC) categories, enabling the provision of comprehensive one-stop solutions encompassing chips and underlying algorithms required for smart control. Historically, performance has been primarily driven by sales of MCU, SoC, and ASIC solutions and related products.
Specifically, MCU solutions contributed 75.4% of revenue in 2025. These products, covering 8-bit and 32-bit series, are widely used in applications such as home appliances, smart meters, and basic automotive modules due to their low power consumption, high reliability, and cost-effectiveness. SoC products, which are highly integrated with multi-functional modules supporting multi-core parallel processing and complex computations, saw their revenue share increase to 21.5% in 2025. Fully customized ASICs, focused on specific functional requirements, accounted for 2.8% of revenue in the same year.
In terms of market positioning, the company has developed a dual-core competitive edge spanning broad consumer applications and high-end sectors. In the broad consumer domain, its MCU chips hold a leading position in consumer electronics and smart home appliances. By revenue in 2024, it ranked first in the Chinese MCU chip market for smart home appliances and second in the consumer electronics MCU chip market. Concurrently, the company has successfully overcome barriers to high-end MCU applications, entering the high-growth fields of industrial control and automotive electronics. Data shows that in 2024, its MCU products held the top position in China by shipment volume with a 12.6% market share, ranking third by revenue.
Operationally, the company employs a hybrid "fabless plus own production line" model, balancing large-scale delivery needs with requirements for flexible iteration. It focuses on core aspects like chip design, platform development, and market innovation, maintaining long-term partnerships with leading global wafer foundries and packaging and testing service providers to ensure efficient mass production and delivery. Additionally, it operates its own packaging and testing production line in Suining. In 2025, this line achieved packaging capacity of 120 million units and testing capacity of 1.2 billion units, with utilization rates of 74.9% and 65.9% respectively. It primarily handles rapid packaging and testing for new products, customized packaging, and final product testing.
Financially, the company demonstrated a turnaround to profitability and maintained a robust financial structure. Revenue grew steadily from 714 million yuan in 2023 to 1.122 billion yuan in 2025. The gross profit margin improved consistently from 9.7% to 32.9%, a enhancement directly linked to the increasing proportion of high-end businesses like SoC, industrial control, and automotive electronics. The growing penetration of these high-value-added products effectively boosted overall profitability.
Regarding profit performance, the company showed significant recovery amid industry cyclical fluctuations. It recorded a loss of 21.949 million yuan in 2023, impacted by an industry downturn and inventory adjustments. However, with recovering downstream demand, optimized product mix, and effective cost control, it returned to profit in 2024, achieving a net profit of 137 million yuan. Profit further increased to 284 million yuan in 2025. Cash flow and asset structure remained stable. Net cash flow from operating activities reached 300 million yuan in 2025, providing reliable funding support for ongoing R&D investment, capacity optimization, and market expansion. As of the end of 2025, total assets stood at 3.679 billion yuan, with net assets of 3.177 billion yuan, and the asset-liability ratio remained at a relatively low level.
R&D capability and customer resource advantages are core drivers of the company's performance growth. By the end of 2025, it employed 241 R&D personnel, accounting for 52.5% of the total workforce, forming a complete technical team covering chip design, analog circuits, and embedded algorithms. R&D expenditure remained stable between 120 million and 130 million yuan annually from 2023 to 2025, with a cumulative investment exceeding 370 million yuan over three years. The company has accumulated 17 core technologies and holds 72 patents, 228 integrated circuit layout designs, and 28 copyrights. In 2024, it obtained ISO 26262 automotive functional safety ASIL D process certification, reaching industry-advanced levels for automotive-grade chip capability and further opening up opportunities in high-end markets.
On the customer front, by the end of 2025, the company served over 1,000 customers, including leading enterprises and well-known brands in consumer electronics, smart home appliances, industrial control, and automotive electronics. Customer retention rates were 63.5%, 73.2%, and 82.8% for 2023, 2024, and 2025 respectively, indicating steadily increasing customer loyalty.
Favorable industry trends and the deepening of domestic substitution provide additional growth momentum. As the penetration rate of smart control chips increases in sectors like home appliances, industrial, and automotive, demand for MCUs and SoCs in the domestic market continues to expand, offering broader opportunities for local manufacturers with established technology and customer bases. This serves as significant external support for the company's performance recovery and structural upgrade.
The global semiconductor industry continues to grow, with the Chinese market exhibiting leading growth rates. MCUs, as core components for smart control, are in sustained high demand. The Chinese MCU market size reached 56.8 billion yuan in 2024 and is projected to increase to 96.9 billion yuan by 2029, representing a compound annual growth rate of 11.3%. Emerging fields like automotive electronics, edge AI, and robotics are key growth drivers. The SoC market also holds substantial potential, with the Chinese market size expected to reach 637 billion yuan by 2029, a CAGR of 13.3%, providing ample space for the synergistic development of multiple product lines.
According to the listing plan, the funds raised in Hong Kong will be primarily used for four areas: enhancing R&D capabilities, strategic investments and acquisitions, establishing a Hong Kong global operation and R&D center, and supplementing working capital. R&D investments will focus on high-computing-power automotive-grade MCUs, industrial control motor driver chips, and specialized AI and robotics chips to further strengthen technological barriers. The establishment of the Hong Kong global operation and R&D center aims to integrate international resources, accelerate overseas market expansion and high-end talent acquisition, advance global layout, and enhance international brand influence.
While the company faces common risks such as semiconductor industry cyclicality, its strategy of multi-foundry partnerships, diversified application scenarios, and relatively sound financial condition provide a degree of risk mitigation. The establishment of the dual capital market platform is expected to further diversify financing channels. Leveraging the international nature of the Hong Kong market could facilitate access to long-term capital and industrial cooperation resources.
Amid the broader trend of domestic substitution in China's semiconductor industry, the company, backed by its existing market share, technological储备, customer resources, and financial foundation, possesses a solid base for further expansion in high-end sectors like industrial control and automotive electronics. As capital support materializes, R&D investments and global布局 are likely to intensify, potentially leading to continuous optimization of the business structure. Future performance remains subject to ongoing market observation.
