• Value-added services: assembly, surface treatments, and logistics form incremental revenue and strengthen customer lock-in.

• The 2.45 billion CNY sales figure for the first nine months of 2025 signals robust demand across electronics, medical, and automotive segments despite a reported net loss of 114.78 million CNY in the period.
• Causes of near-term loss can include higher material costs, ramp-up costs for new product lines, capacity expansion, FX effects on export sales, or one-off charges tied to investment in automation or quality systems.
• Persistent relationships with several Fortune 500 firms underpin recurring revenue potential and support volume-driven margin recovery as efficiency measures and pricing adjustments take effect.

Kunshan Kersen Science & Technology Co.,Ltd. (603626.SS): How It Makes Money

• Primary revenue sources: precision metal parts manufacturing (stamped parts, CNC machined parts, metal housings), assembly services, and tooling/fixture sales.
• Customer mix: a blend of global OEMs including several Fortune 500 companies and medium-sized manufacturers across multiple end markets.
• Geographic revenue exposure: domestic China sales plus exports to the United States, Philippines, Japan, Italy and India.

• Economies of scale from high-volume stamping and machining lines that lower unit costs for large OEM contracts.
• Export orientation - diversified end markets reduce reliance on any single region and allow margin arbitrage across currencies.
• Quality systems and international certifications that enable premium OEM contracts and recurring orders.
• Vertical integration of tooling, machining and assembly to capture higher value content per product.
• Regional manufacturing footprint expansion (Vietnam subsidiary) to improve lead times, labor cost structure and access to Southeast Asian customers.

• Kersen is recognized as a leading manufacturer of precision metallic components with a global customer base; this reputation supports stable OEM contract wins and repeat revenue.
• The company's export reach (notably to the U.S., Japan and European markets) positions it to capture demand from multinational OEMs, supporting revenue diversification.
• Its Vietnam subsidiary (established 2023) is expected to improve competitiveness in Southeast Asia and serve as a platform for incremental sales growth.
• Although Kersen recorded a net loss in H1 2025, strategic initiatives-capacity adjustments, margin-focused contract bidding, and continued quality certification-aim to restore profitability and revenue growth.
