Core Highlights: Hidden Champion of Industrial & Scientific Imaging CIS, Independent Technology Builds Moat

Leading Global Market Position
Gpixel’s core strength lies in its global leading position in the high-barrier niche of industrial and scientific imaging CIS.
According to Frost & Sullivan, based on revenue in 2024, the company ranked third among global industrial imaging CIS providers with a market share of 15.2%, and also third among global scientific imaging CIS providers with a market share of 16.3%.
In the high-end market dominated by a small number of international and regional leaders, the company has established a solid competitive position with independent technologies.
14 Years of Independent Innovation Creates Technical Moat
Since its establishment in 2012, the company has focused on CIS R&D and successfully overcome a number of key technical challenges.
In 2015, it developed the world’s first BSI sCMOS image sensor, and later expanded into industrial imaging, professional imaging, medical imaging and other fields.
As of the Latest Practicable Date, the company has established 11 core proprietary technologies, including global shutter pixels, HDR pixels, high-sensitivity pixels and 3D wafer stacking, and owns 61 registered patents worldwide.
The company has successively developed China’s first full-frame, BSI and stacked CMOS image sensors, breaking the reliance on imported ultra-high-definition imaging solutions.
Comprehensive Product Matrix with Wide Application Scenarios
The company has built nine product series and more than 50 standard products, divided into area scan sensors and line scan sensors by pixel arrangement.
They are widely used in high-end fields such as lithium battery manufacturing inspection, DNA sequencing imaging, confocal microscopy, fluorescence cameras and professional cinema cameras.
In 2025, CMOS image sensor revenue reached RMB 795 million, accounting for 92.8% of total revenue.
Among them, area scan sensors generated revenue of RMB 621 million (72.5%), line scan sensors RMB 133 million (15.5%), and custom sensor solutions RMB 61 million (7.1%).
Fabless Model Focuses on Core Competitiveness
The company adopts a fabless business model, focusing on CIS design, development, testing and sales.
It outsources wafer manufacturing to world-class production partners such as Tower and DB HiTek, while retaining full control over core processes including sensor design, wafer testing and final sensor testing.
The company has also built an independent testing platform and inspection system, and strategically expanded sensor packaging capacity.
At present, its monthly output of high-reliability ceramic packages exceeds 20,000 units, effectively reducing dependence on external suppliers.

Financial Performance: Rapid Growth in Revenue and Profit, Strong Profitability

Gpixel’s financial data shows rapid revenue growth, strong profit expansion, industry-leading gross margins and ample operating cash flow.
Sustained High Revenue Growth
The company’s revenue rose from RMB 605 million in 2023 to RMB 673 million in 2024, representing a year-on-year increase of 11.3%, and further grew to RMB 857 million in 2025, up 27.3% year-on-year, showing strong growth momentum.
Although the industrial and scientific imaging CIS market accounts for only about 2.9% of the global CIS market, the company has continuously expanded its share in the segment with technological advantages.
Industry-Leading Gross Margins and Strong Profitability
The company’s gross margins were 63.5%, 59.0% and 66.9% from 2023 to 2025, among the top levels in the chip design industry.
Net profit grew from RMB 170 million in 2023 to RMB 197 million in 2024, up 16.0% year-on-year, and reached RMB 293 million in 2025, up 48.7% year-on-year.
Profit growth significantly outpaced revenue growth, reflecting continuous release of economies of scale and operating leverage.
Net profit margin increased from 28.1% to 34.2%, with continuously improving profitability.
Ample Operating Cash Flow and Healthy Financial Position
The company’s operating cash flow remained positive and grew steadily, rising from RMB 208 million in 2023 to RMB 225 million in 2024 and further to RMB 466 million in 2025, representing excellent cash flow performance.
Net assets increased from RMB 963 million in 2023 to RMB 1.572 billion in 2025, with a robust asset-liability structure, providing sufficient financial space for subsequent capacity expansion and technological R&D.

Risk Concerns: Customer Concentration, Inventory Management and Supply Chain Dependence

Customer Concentration Risk
Revenue from the company’s top five customers accounted for 45.8%, 33.5% and 40.7% from 2023 to 2025 respectively.
Among them, revenue from Customer Group A (including major shareholder OPU Photo-Electric) accounted for 18.2%, 5.9% and 3.2% respectively, showing a downward trend.
In addition, the revenue share of research institute customers decreased from 27.3% to 5.1%, while that of camera manufacturers and OEM customers rose from 61.7% to 81.6%.
The customer structure has shifted toward commercial customers, but certain concentration risks remain.
Inventory Management Risk
As of December 31, 2025, the company’s inventory reached RMB 353 million, with inventory turnover days as high as 412, representing a relatively high level.
The company’s products are mainly high-end customized CIS with long R&D and production cycles.
As the company moves into the mainstream product market, inventory levels may rise further.
Changes in market demand or technological obsolescence could lead to inventory impairment losses, with inventory provisions reaching RMB 46.3 million in 2025.
Supply Chain Dependence Risk
As a fabless company, the company outsources wafer manufacturing to third-party suppliers.
From 2023 to 2025, purchases from the top five suppliers accounted for 74.7%, 63.7% and 70.5% respectively, with the largest supplier (Supplier Group A) accounting for 51.1%, 39.7% and 50.1% respectively.
The highly concentrated supply chain exposes the company to risks including supply disruption, price fluctuations and counterparty risks.

Conclusion

Overall, as a leading global player in industrial and scientific imaging CIS, Gpixel has successfully attracted a number of renowned cornerstone investors with a total subscription of approximately US$166 million, accounting for about 50.0% of the global offering, further confirming global capital’s high recognition of the company’s development prospects.
However, the company still faces risks including relatively high customer concentration, long inventory turnover days and a highly concentrated supply chain.
After listing, the market will continue to focus on how the company consolidates its advantages in industrial and scientific imaging, effectively expands into the mainstream product market, optimizes inventory management, deepens supply chain cooperation and continuously promotes technological innovation.
