Chengdu Kanghua Biological Products Co., Ltd. (300841.SZ): How It Works

• Core capabilities: in-house R&D, GMP-certified production lines, quality control labs, regulatory affairs and clinical development teams.
• Product pipeline focus: licensed rabies vaccines, recombinant norovirus vaccines, and platform expansion into multivalent and recombinant subunit vaccines.
• Distribution channels: direct sales to hospitals and clinics, public health tenders, distributors for export markets, and licensing partners.

• Product sales - primary revenue from marketed vaccines (human diploid cell rabies vaccine and other on-market products).
• Licensing & technology transfer - milestone and royalty income from domestic and overseas licensing deals (including the recombinant hexavalent norovirus vaccine licensing agreement for export markets).
• Government contracts and tenders - supply agreements for provincial and national immunization programs leveraging Kanghua's GMP-certified manufacturing.
• Commercialization of R&D outputs - revenue realization from newly approved vaccines and lifecycle management of existing products.
• Strategic investments & partnerships - capital injections and joint-development funding, including the proposed acquisition/support by Shanghai Healthcare M&A Fund to scale production and market access.

• Marketed vaccine sales: steady, recurring income from domestic immunization and private-market purchases; seasonal and tender-driven variations affect quarter-to-quarter revenue.
• Licensing deals: significant one-time and ongoing royalty streams - the overseas licensing of the recombinant hexavalent norovirus vaccine is a key near-term revenue catalyst.
• Public procurement: winning provincial and national tenders provides volume stability and supports utilization of high-capacity GMP lines.
• R&D commercialization: approvals for new indications or new vaccine formulations convert accumulated R&D spend into product revenues and margin expansion.
• Strategic funding & M&A support: external capital (e.g., from Shanghai Healthcare M&A Fund) underpins capacity expansion, market entry costs and co-development agreements that accelerate revenue scale-up.

• Domestic tender wins: supply contracts to provincial CDCs and public hospitals for rabies vaccine procurement.
• Overseas licensing: partner manufacturing or distribution agreements where Kanghua receives upfront payments, milestones and royalties for the recombinant hexavalent norovirus vaccine.
• Direct export: select markets purchased directly via distributors leveraging Kanghua's regulatory dossiers and quality certifications.
• Co-development/joint ventures: sharing development costs and future revenue with strategic healthcare investors to de-risk late-stage programs.

• Capacity expansion of GMP-certified lines to increase dose output and enable larger public contracts.
• Regulatory dossier strengthening for international approvals to broaden export footprints and licensing attractiveness.
• Targeted business development to secure licensing partners in Asia, Africa and Latin America for recombinant vaccine platforms.
• Capital and strategic support from investors such as the proposed Shanghai Healthcare M&A Fund transaction to accelerate commercialization and market penetration.

Chengdu Kanghua Biological Products Co., Ltd. (300841.SZ): How It Makes Money
