Amidst a profound restructuring of the global semiconductor industry and the sweeping waves of AI and automotive electrification, the independent innovation and global deployment capabilities of Chinese semiconductor companies are being tested like never before. As a leading enterprise in China's analog chip sector, Sg Micro Corp (SHE: 300661), which debuted on the Shenzhen Stock Exchange's ChiNext board in 2017, is now setting its sights on the international capital market. Following two listing applications, the company has successfully passed a listing hearing for the main board of the Hong Kong Stock Exchange, with China International Capital Corporation and Huatai International acting as joint sponsors. What are the highlights of this renewed push into the capital markets?
Examining Growth Resilience Through Revenue Structure
Sg Micro Corp's core business focuses on the design, development, and sale of analog integrated circuits, primarily covering the two major fields of signal chain and power management, supplemented by sensor products. By the end of 2025, the company possessed over 6,800 products spanning 38 categories. This exceptionally broad product portfolio forms its most critical competitive advantage, enabling it to serve multiple end markets including industrial and energy, automotive electronics, networking and computing, and consumer electronics.
Financial performance is a key metric for gauging a company's competitiveness. Sg Micro Corp has demonstrated a steady trajectory of earnings growth over the past three years. Data indicates the company's total revenue grew from RMB 2.616 billion in 2023 to RMB 3.898 billion in 2025, achieving a compound annual growth rate of 22.1%. Notably, after weathering the impact of the global semiconductor industry downturn in 2023, the company's revenue rebounded rapidly by 28.0% in 2024 and maintained 16.5% growth in 2025, showcasing strong recovery resilience in its business.
Looking at the revenue composition, power management integrated circuits constitute the primary revenue source, but signal chain integrated circuits show a more pronounced growth momentum. From 2023 to 2025, the revenue share from power management ICs gradually decreased from 66.8% to 61.1%, while the revenue share from signal chain ICs increased from 33.0% to 37.7% over the same period. This structural shift reflects the company's positive progress in the high-tech-barrier field of signal processing, where products like amplifiers and analog-to-digital converters are gaining greater market acceptance, which helps optimize the overall profit structure.
Performance on the profit side is also commendable. Adjusted net profit significantly increased from RMB 389 million to RMB 693 million during the same period. In terms of profitability, the company's gross profit margin fluctuated within a range of 44.9% to 47.2%, recording 46.2% in 2025, remaining at a relatively high level. This level is quite competitive within the chip design industry, primarily benefiting from the company's continuous launch of new high-performance products and contributions from signal chain ICs.
However, it is noteworthy that the company's R&D investment is substantial, with R&D expenses reaching RMB 1.045 billion in 2025, accounting for a high 26.8% of total revenue. While significant R&D spending is a necessary condition for semiconductor design firms to maintain technological leadership, it also exerts some pressure on short-term net profit margins. Additionally, the company's inventory turnover days increased from 203 days in 2023 to 228 days in 2025, reflecting a strategy of proactively increasing inventory to meet anticipated market demand growth. However, if future demand falls short of expectations, the higher inventory level could pose impairment risks.
From the latest operational dynamics, the company's revenue for the first quarter of 2026 grew 39.1% year-over-year to RMB 1.098 billion, and net profit surged 109.3% year-over-year to RMB 123 million, demonstrating strong growth momentum. However, single-quarter data is insufficient to alter the judgment of the full-year trend.
Striking a Balance Between Opportunity and Dependence
From an industry perspective, the sector in which Sg Micro Corp operates has a promising outlook but a fragmented competitive landscape. According to data, the market size for analog integrated circuits in China is projected to reach RMB 389.4 billion by 2030, with a compound annual growth rate of 12.2%. In this market, Sg Micro Corp has established itself as a leading domestic player, ranking first among Chinese manufacturers in areas such as amplifiers and comparators within the signal chain field, and LDO and AMOLED power supply chips within the power management field.
Nevertheless, the global market is still dominated by international giants like Texas Instruments and Analog Devices, with the top eight manufacturers collectively holding a 37.3% market share. As the largest domestic Chinese manufacturer, Sg Micro Corp holds a 1.8% share. This highlights both the vast potential for import substitution and the gap with leading international firms in terms of brand, product line breadth, and process technology accumulation. The company is working to narrow this gap by expanding into high-end applications such as automotive and server power management, currently having nearly 500 mass-produced automotive-grade chips.
Beyond this, several risk factors warrant market attention. The first is high dependence on the supply chain. As a fabless chip design company, Sg Micro Corp outsources all wafer manufacturing, packaging, and testing. In 2025, the company's top five suppliers accounted for 91.0% of total procurement, with the largest single supplier accounting for nearly 40%. While such concentration is common within the industry, in the semiconductor sector characterized by complex geopolitics and tight capacity, any production disruption or deterioration in the relationship with a major supplier would pose a direct threat to the company's product delivery. In the current environment of structural tightness in global semiconductor capacity, ensuring supply chain autonomy, control, and diversification is a top priority that Sg Micro Corp must address.
Furthermore, the analog chip industry exhibits significant cyclical characteristics and is closely tied to macroeconomic conditions and consumer electronics demand. The industry downturn in 2023 led to a decline in the company's revenue. Although growth resumed thereafter, uncertainties in the pace of global economic recovery, inflation, and regional trade frictions could still suppress end-demand.
Reviewing Sg Micro Corp's prospectus reveals a typical profile of a growing Chinese technology company: it possesses core technology, occupies a favorable market position, and has delivered excellent growth performance in recent years. Particularly in the first quarter of 2026, the company recorded impressive year-over-year increases of 39.1% in revenue and 109.3% in net profit, demonstrating strong operational resilience. The company's pursuit of a Hong Kong listing, aiming to accelerate its globalization strategy by introducing international capital, is undoubtedly a wise and necessary step.
However, Sg Micro Corp's development path is not without challenges; it currently stands at a critical crossroads. It needs to overcome technological barriers in high-end signal chain and automotive electronics to narrow the gap with international giants while pursuing scale expansion. It must embrace globalization while guarding against the potential risks of a highly concentrated supply chain. While investors may pay for its technological prowess and market position, they must also clearly recognize that this is not merely a capital feast, but a prolonged test of technology, management, and strategic resolve.
