EXECUTIVE SUMMARY / 研报摘要
CoWin Biotech is one of the few Chinese biotechnology companies with a fully integrated molecular diagnostics value chain, spanning core raw enzymes, nucleic acid preservation reagents, extraction/purification reagents, molecular diagnostic kits and downstream gene sequencing/synthesis services. In FY2025, the company reported revenue of RMB 193.5 million, up 53.7% year-over-year, driven primarily by explosive growth in gene sequencing and gene synthesis service revenue, which surged 474% to RMB 78.5 million. However, the company remained loss-making at the net level, with a net loss of RMB 107.4 million, though this represented a 31.7% reduction from the prior year's loss. The gross margin compressed to 45.4% from 55.9% as the revenue mix shifted toward lower-margin service businesses. R&D spending declined 22% to RMB 77.4 million, reflecting a strategic pivot toward commercialization and cost optimization. With 105 authorized patents, 83 domestic medical device registrations and 73 overseas registrations, the company maintains a solid IP portfolio. We view CoWin Biotech as a fundamentally sound but currently undervalued platform company at a critical commercial inflection point, with key catalysts being H. pylori diagnostic product adoption and scale economies in the nano-porous sequencing service business. The primary risks are prolonged cash burn, slower-than-expected new product commercialization, and margin dilution from the service mix shift.
1. Company Overview
CoWin Biotech (Jiangsu CoWin Biotech Co., Ltd.) was founded in 2010 and listed on the STAR Market of the Shanghai Stock Exchange in October 2022 under the ticker 688426.SH.

10. Investment Conclusion & Enterprise Quality
Enterprise Quality Assessment: CoWin Biotech presents a mixed picture of enterprise quality. On the positive side, the company possesses genuine technological depth, a complete value chain integration model, a solid IP portfolio, and exposure to structurally growing end markets. The rapid growth of the service business demonstrates the company's ability to identify and capture new revenue opportunities. The significant reduction in net losses (31.7% improvement YoY) and operating cash flow deficit (from RMB -113.3 million to RMB -59.0 million) indicates progress toward financial sustainability.
However, several quality concerns warrant attention. The company remains deeply loss-making with a net margin of negative 55.5%, and the path to profitability remains uncertain. Gross margin compressed significantly from 55.9% to 45.4% due to the revenue mix shift toward lower-margin services, raising questions about the quality of growth. The service business, while growing rapidly, operates at only 12.2% gross margin, well below industry benchmarks for diagnostic services, and management itself acknowledges that 'scale economies have not yet materialized'. R&D spending declined 22% YoY, which could impair long-term competitiveness if sustained.
Valuation Perspective: At a market capitalization of approximately RMB 2.25 billion and FY2025 revenue of RMB 193.5 million, the company trades at a price-to-sales ratio of approximately 11.6x, which appears stretched relative to its current growth trajectory and profitability profile. The market is clearly pricing in significant future growth, particularly in the service business and H. pylori diagnostics, which may or may not materialize.
- Successful commercialization of H. pylori molecular diagnostic products in 2026, with potential adoption in hospitals, physical examination centers, enterprises, and insurance channels
