Resilient Supply Chain

Developing a resilient supply chain and safeguarding business continuity are paramount to the Company's sustainable supplychain strategy. We have implemented a sophisticated risk analysis model and assessment mechanism to conduct comprehensiveevaluations of various supplier categories. This approach focuses on risk identication, potential loss quantication, and specicmitigation strategies. By proactively refining our supply chain safeguards, we effectively mitigate potential risks throughout thesupply network. In 2024, the Company maintained uninterrupted raw material supplies, avoiding any production disruptions due tomaterial shortages.

Our supply chain risk assessments are grounded in thecriticality of materials to production processes and theprobability of supply interruptions. We develop tailoredsafeguarding strategies that consider the severity of impacton production activities, the likelihood of supply delays, andthe detectability of such disruptions. High- and medium-riskmaterials are subject to intensied monitoring to ensure timelyavailability for commercial production projects.

To hedge against price volatility and ensure superior after-sales service, we engage in annual agreements with suppliersbased on long-term collaboration principles or establishstrategic alliances. This approach prioritizes the procurementof scarce materials and minimizes distribution risks.

We have established multi-channel communicationplatforms with suppliers, including email, telephone, videoconferencing, and in-person meetings. A Delivery WarningNotication protocol has been implemented, initiating supplierengagement at least one month prior to contractual deliverydates to assess readiness. We provide formal monthly writtenfeedback to suppliers on delivery performance, facilitatingcontinuous improvement in on-time delivery. Proactivecommunication with suppliers addresses potential issuesidentified during monitoring, such as supply shortfalls. Wepromptly arrange meetings with suppliers experiencingconstraints to collaboratively develop solutions, ensuringoptimal inventory management and supply stability.

Enhancing Supply Chain Contingency Plans

Maintaining Stable Partnerships

Timely Communication and Information Sharing

To counteract upstream supply disruption risks stemming fromclimatic, geographical, or regulatory factors and to ensureproduction continuity, we adhere to principles of "compliance,stability, timeliness, cost-effectiveness, and strategicimportance." Our management policy mandates at least twosuppliers for each material. We have diversied our key rawmaterial supplier base across different regions, securinga minimum of two domestic and international suppliers forcritical materials, while also identifying backup suppliers. Wehave established preventive measures to mitigate supplydelays and over-dependence on single, high-cost suppliers,thus further reducing production vulnerabilities in the supplychain.

We have implemented inventory management systems forproduction-critical materials, including raw materials andkey consumables, featuring safety stock alert mechanisms.These systems enable real-time monitoring and dynamicmanagement of material inventory data. Our risk mitigationstrategies encompass early demand forecasting and strategicstockpiling, with particular emphasis on enhancing earlywarning controls and increasing inventory levels for criticalmaterials.

We conduct comprehensive assessments of import materialsupply risks, considering historical delivery performanceand inventory levels. We actively explore opportunities fordomestic substitutes and local sourcing, particularly for criticalmaterials, evaluating technical specifications, commercialviability, production capacity, and accessibility to enhanceour supply chain resilience. During the reporting period, YuxiZerun, Walvax Biotechnology' subsidiary, achieved 100%domestic substitution for single-use sterile storage bags,with ongoing initiatives to localize the sourcing of lters andconsumables.

In an e?ort to foster a fair and equitable marketing environment and extend the benets of high-quality vaccine products to a widerpopulation, Walvax Biotechnology has developed the Walvax Biotechnology Co., Ltd. Fair Pricing Policy. In alignment with the WorldHealth Organization's guidelines on fair pricing, the Company adopts a value-based and transparent pricing strategy that balancesproduct quality with a?ordability. Sustainable pricing models are explored across various markets, with pricing policies extended todownstream distributors to ensure consistent implementation and improved product accessibility. Our comprehensive pricing modeltakes into account global market demands, considering factors such as vaccine research and production costs, market supply anddemand dynamics, and pricing of comparable vaccine products. We employ a tiered pricing strategy, o?ering more favorable ratesto economically disadvantaged countries and populations, thereby extending the benefits of vaccine innovation to underservedregions. Detailed information on our fair pricing principles can be found in the Walvax Biotechnology Co., Ltd. Fair Pricing Policy andthe Walvax Biotechnology Co., Ltd. 2023 Sustainability & ESG and Social Responsibility Report.

Increasing Product A?ordability

In the domestic market, the Company complies with relevant legal regulations, ensuring fair and reasonable pricing for its high-quality vaccines, with consistent pricing nationwide. Prices are publicly available and transparent across all regions, accessible viaprovincial-level platforms. We strive to balance scale and e?ciency, o?ering vaccine products at competitive prices. For successfulbid products, we strictly adhere to regulations by promptly publishing information on the central government procurement website.As of the end of the reporting period, two of our marketed vaccine products are included in the national immunization program,with procurement prices regulated and guided by the state, provided free of charge to residents. In 2024, the procurement volumefor these two immunization program vaccines exceeded 7.5 million doses. Moreover, we actively address the needs of specicpopulations by participating in various local welfare procurement projects and o?ering substantial corporate concessions. Currently,both our bivalent HPV vaccine and 23-valent pneumococcal vaccine have secured bids in multiple government procurementprojects. Furthermore, we monitor end-of-supply chain prices to prevent price gouging and welcome public scrutiny.Our self-developed bivalent HPV vaccine was initially priced at RMB 329 per dose at launch. Compared to the imported bivalentHPV vaccine already on the market, this can result in savings of approximately RMB 812 for a complete 3-dose regimen. In 2024,the price of this vaccine in some regions was reduced by about 40.43% from our initial recommended price, potentially savingapproximately RMB 399 for a complete 3-dose regimen. This allows more people to access equally safe and e?ective high-qualityvaccines at a lower cost.

In overseas markets, the Company adheres to local pricing regulations and tax policies and has established the WalvaxBiotechnology Co., Ltd. Overseas Sales Pricing Management Measures. We have developed accessible pricing strategies tailoredto the needs and economic development levels of di?erent countries or regions. Our approach considers factors such as nationalor regional economic development, local vaccine production and supply, public healthcare investment, individual healthcarecosts, vaccine procurement budgets and policies, and the overall benets of vaccines to populations and healthcare systems. Weimplement di?erentiated pricing models and tiered strategies. While ensuring necessary prot margins, product quality, and stablesupply, we o?er more favorable vaccine prices to economically disadvantaged countries and populations. For instance, we providevaccines at lower prices to low-income African countries such as Mauritania and Burkina Faso compared to other internationalmarkets.The Company recognizes the vital role that centralized procurement plays in reducing costs, improving vaccination coverage, andadvancing public health. To this end, we actively promote the inclusion of our vaccine products in local immunization programs.

In 2024, Yuxi Walvax continued to enhance its investment in wastewater treatment facilities, implementing advancedMBR (Membrane Bioreactor) technology for further processing of aerobic tank effluent. This initiative not only ensuredcompliance with discharge standards, further reduced concentrations of pollutants such as ammonia nitrogen, signicantlyimproving the overall e?ectiveness of wastewater treatment. A comprehensive upgrade of the existing wastewater treatmentsystem was undertaken, including the addition of aerobic tank media and a full automation overhaul. These improvementsboosted wastewater treatment capacity while simultaneously enhancing the industrial park's aesthetic appeal. The minimalodors generated by the wastewater treatment plant are naturally absorbed by surrounding vegetation, further mitigatingenvironmental impact.

The Company's wastewater is primarily generated from domestic sewage, discharges from the circulating cooling system, ande?uents from research and production activities. It strictly complies with relevant laws and regulations, including the Law of thePeople's Republic of China on Water Pollution Prevention and Control, Discharge Standard of Industrial Water Pollutants, andDischarge Standards of Water Pollutants for Pharmaceutical Industry Bio-pharmaceutical Category. The Company has alsoimplemented a series of internal guidelines, such as the Walvax Biotechnology Waste Liquid Disposal Standard ManagementProcedure, which regulate wastewater treatment procedures, monitoring protocols, and operational requirements.

Our drainage system separates rainwater from sewage, and clean water from wastewater. All biologically activewastewater undergoes high-temperature inactivation (121°C for over 30 minutes) before being mixed with otherproduction wastewater and domestic sewage. This ensures that all wastewater is collected through sealed pipelinesand fully treated in septic tanks and wastewater treatment facilities, meeting the Discharge Standards of WaterPollutants for Pharmaceutical Industry Bio-pharmaceutical Category (GB21907-2008) before discharge into themunicipal sewage network.We have implemented an online monitoring system for real-time wastewater discharge surveillance. The Companyoperates 3 discharge outlets: 1 main wastewater outlet and 2 rainwater outlets. Data from the main wastewateroutlet is linked to national, provincial, and municipal environmental protection departments, enabling joint monitoringof wastewater ow, pH value, chemical oxygen demand, ammonia nitrogen, and other discharge parameters.
