Shenzhen Kangtai Biological Products Co., Ltd. (300601.SZ): How It Works

• Primary revenue sources: commercial sales of vaccines (hepatitis B, pneumococcal, COVID‑19, influenza, HPV candidates), government/public immunization program contracts, and technology/licensing deals.
• Geographic reach: direct sales and distribution covering all 31 provinces in mainland China through provincial distributors and regional sales teams.
• R&D and pipeline: internal R&D for next‑generation and combination vaccines, plus contract manufacturing for partners.
• Quality and compliance: multiple GMP facilities, ISO and national regulatory certifications supporting sustained procurement and export eligibility.

• Product sales - core vaccines sold to hospitals, CDCs and immunization clinics; tenders for public immunization programs form a steady base.
• Commercial contracts - bulk supply agreements and seasonal campaigns (e.g., influenza) bolster episodic revenue.
• Partnerships & licensing - strategic alliances (notably with international firms) for co‑development, production and distribution of proprietary vaccines.
• Export & OEM - selected international shipments and contract manufacturing for third parties add incremental margin.

• Vaccine product mix: routine vaccines (hepatitis B and others) provide stable baseline sales; pneumococcal and COVID‑19 products contributed elevated revenue during and after pandemic peaks.
• Shift toward higher‑value products: introduction and scaling of conjugate and recombinant vaccines improved ASPs (average selling prices) and margins.
• Public procurement & tenders: a material share of annual volume is supplied via provincial CDC tenders, supporting predictable demand.

• AstraZeneca agreement: collaboration for COVID‑19 vaccine manufacturing and distribution broadened capacity utilization and market reach.
• International collaborations: tech transfers and co‑development deals enable entry into select overseas markets and OEM revenue.
• Provincial network: centralized manufacturing with decentralized sales-regional distributors and CDC channels in 31 provinces-drive penetration and scale.

• Scale manufacturing: multiple GMP lines enable lower unit costs as volumes scale.
• Vertical integration: in‑house antigen production, filling & packaging reduce third‑party costs and protect margins.
• Pipeline commercialization: steady R&D spend (~5% of revenue) converts into new product approvals and lifecycle extensions, replenishing growth drivers.
