Agriculture and Animal Husbandry
Furthermore in the lifecycle management of agri-animal husbandry products the Company fully considers the natural properties and safety risks of raw materials from the product
design stage. For natural hazards such as heavy metals and mycotoxins that may arise from objective factors like geographical environment climate harvesting and storage of raw
materials like grains and crops the R&D team mitigates or dilutes potential risks at the source through scientific raw material combinations and nutritional adjustments in product
formula design. This effectively reduces resource waste and environmental burdens caused by non-compliant raw materials. At the same time by prioritizing the procurement of raw
materials that meet local environmental standards and establishing a raw material risk database and dynamic assessment mechanism the Company systematically analyzes the
characteristic indicators historical testing data and environmental conditions of various raw materials. This approach reduces the potential negative social impacts on farmers'
livelihoods producers' interests and public health that could be caused by raw material contamination or quality defects shifting safety controls upstream to the formula design
stage. This design-driven risk management strategy not only ensures the achievement of a 100% pass rate for finished products but also consistently supports a 100% pass rate for
feed products in various supervisory spot checks.New Product Introduction Incoming Material Management In-Process Management Outgoing Inspection Customer Management

Strategy
Tongwei deeply integrates climate resilience into the development of its dual core businesses of “green energy + green agriculture”. Anchored by the goal of “strive to achieve carbonneutrality at the operating level before 2030” the Company has formulated and is implementing a phased climate action strategy. The Company enhances its short- medium- and
long-term climate change response capabilities from three dimensions: strategic development asset allocation and financial resources. It fully embeds climate considerations into
production operations and supply chain management using its professional capabilities to support value chain partners in jointly addressing climate challenges and promoting
steady improvement in climate governance performance.Tongwei pays close attention to the impact of climate change on the Company's financial fundamentals proactively coordinates the allocation of climate-related resources and cost
inputs and actively explores the application of green finance tools to prevent potential risks from climate change and seize opportunities related to the low-carbon transition.Currently the Company has begun collecting current and prospective climate-related financial indicators and is conducting scenario analysis for physical and transition risks to
identify and assess the qualitative current and expected financial impacts of physical risks transition risks and transition opportunities. The assessment indicates that the current
and expected financial impacts of physical and transition risks are generally manageable while the impacts of transition opportunities are more significant. This requires further
efforts to identify transition opportunities and coordinate resources to deeply integrate the Company's low-carbon transition with its high-quality development.Environmental Social and Preface Sustainable Development Management Winning Progress Winning Economy Winning Environment Winning People Appendix

Physical Risks
Tongwei uses climate scenario analysis to systematically and quantitatively assess the potential impacts of key climate risks and opportunities on its business operations and financial
performance under different scenarios thereby enhancing climate resilience and supporting relevant strategic and risk management decisions. In with reference to the Fifth and
Sixth Assessment Reports of the Intergovernmental Panel on Climate Change (IPCC) the Company selected Representative Concentration Pathways (RCP) and conducted a physical
risk scenario analysis on its domestic assets with substantial impacts. The Company uses data on the frequency and intensity of 12 types of climate disasters as a basis combined with
the sensitivity of its business models asset types and geographical features to various disasters to derive scores for each climate risk. These scores are then used to calculate the risk
exposure of various physical asset values and the operating revenue risk exposure under different risk levels which serve as core financial indicators for assessing climate-related
financial impacts. Based on internal research and scenario analysis results it was determined that the Company may be exposed to higher risks from extreme heat temperatures
warming trend and wet trend; however the overall physical risks are manageable.Asset Exposure to Physical Risks under RCP4.5 and RCP8.5 Scenarios

Deep Decarbonization of Own Operations
To advance the climate goals of the Paris Agreement and the national strategy for “carbon peaking and carbon neutrality” Tongwei conducts organizational-level carbon accounting in
strict accordance with the ISO 14064 international standard and national industry-specific GHG emissions standards using the operational control approach as the accounting
standard. The Company also encourages its subsidiaries to conduct carbon verification which builds a solid data foundation for dynamically updating its carbon reduction targets and
scientifically formulating carbon management plans.Integrating policy requirements electricity market prices and its own operational realities and referencing shadow carbon pricing theory the Company is exploring the establishment
of an internal carbon pricing mechanism covering Scopes 1 2 and 3. It plans to apply this mechanism to all business and functional departments at the headquarters and to serve as
an internal carbon pricing reference for all subsidiaries and production bases with the aim of conducting cost-benefit analyses driving energy efficiency improvements promoting
low-carbon investments encouraging the inclusion of climate considerations in decision-making and Risk assessment identifying and seizing low-carbon opportunities and thereby
optimizing the Company's future strategic formulation and financial planning.Additionally the Company continuously conducts internal low-carbon transition training and actively participates in carbon footprint-related training organized by government
departments and third-party institutions to systematically enhance the team's ability to identify and quantify climate risks.Tongwei Holds Its Carbon Inventory Kick-Off Meeting and Product Carbon Footprint Training
In December Tongwei held its “Greenhouse Gas Inventory Kick-off Meeting and the Third Carbon Management Special Training on Product Carbon Footprint”. The British
Standards Institution (BSI) was invited to conduct the training based on the “ISO 14067:2018 Product Carbon Footprint” standard. Through a combination of theoretical
explanations case studies and practical exercises the event provided a systematic interpretation of the core knowledge standard requirements and practical methods for
product carbon footprint accounting. The instructor emphasized key skills such as carbon data traceability and quantitative management and control while also reviewing common
issues from ISO 14064 verifications to solidify theoretical knowledge of GHG emissions and help address pain points and difficulties in practical work. A total of over 170 employees
actively participated in the training with 70 trainees successfully passing the examination and receiving qualification certificates from BSI laying a solid foundation of capabilities
for deepening product low-carbon management and aligning with international standards.The GHG Inventory Kick-Off Meeting and the Third Carbon Management Special Training on Product Carbon FootprintEnvironmental Social and Preface Sustainable Development Management Winning Progress Winning Economy Winning Environment Winning People Appendix

Commencement of China's First Market-Based Wind-Solar-Storage Integrated Project for Green Power Silicon Production with Wind-Solar
Coupling
On February 22 construction began on the Inner Mongolia Tongwei Green Base Material's 350000 kW wind-solar-storage integrated project. This is China's first
market-based wind-solar-storage integrated project for green power silicon production with wind-solar coupling featuring a joint-stock collaboration between a Fortune 500
private enterprise and a central state-owned enterprise full self-generation and self-consumption via the grid and a renewable energy share exceeding 50%. The project is
scheduled to connect to the grid in May 2026 with an estimated annual power generation of 930 million kWh which will reduce annual operational carbon emissions by over
600000 tons contributing to optimizing the regional energy supply structure and achieving China's carbon peaking and neutrality goals.
Furthermore the project adopts a “grass-solar complementarity” model integrating photovoltaic power generation with grassland ecological restoration and modern pasture
construction to achieve a win-win for both economic and ecological benefits. By planting grass and raising livestock under the solar panels it promotes the recovery of the
grassland ecosystem while increasing the income of local farmers and herders providing an innovative path for regional sustainable development.Inner Mongolia Tongwei Green Base Material's 350000 kW Wind-solar-storage Integrated Project

Water Risk Assessment
In Tongwei used the latest version of the World Resources Institute (WRI) Water Risk Assessment Tool to conduct a water risk assessment for 90 of its main subsidiaries
identifying water stress and potential risks. Based on the assessment results the Company formulates differentiated water risk management strategies tailored to the total water
consumption and water use structure of each subsidiary. It implements specific measures such as controlling water withdrawal and consumption to enhance water use efficiency and
strengthen the Company's overall sustainable water management capabilities.The assessment results show a differentiated distribution of water-related risks across Tongwei's subsidiaries: some subsidiaries have risks at a controllable level while others face
higher pressure. Based on this the Company needs to formulate targeted management measures for high-risk subsidiaries while maintaining continuous monitoring of low-risk ones
to ensure the achievement of water management and corporate sustainability goals.Water Stress Risk Level Proportion

Distribution of Water Stress Risk for Subsidiaries
Based on the conclusions of the above water risk assessment the Company conducted a further forward-looking water resource risk scenario analysis to quantitatively predict the
physical regulatory and reputation risks in the regions where its main operating bases are located for the years 2030 and 2050. By compiling and presenting the number of operating
sites under different risk levels we clearly reveal the distribution patterns and evolutionary trends of various water resource risks across multiple scenarios providing a reference for
medium- and long-term water resources management and strategic planning.
1 Project Physical risks primarily refer to factors such as water scarcity floods changes in water quality and degradation of ecosystem services which may adversely affect operational stability cost control and
supply chain continuity.
2 Regulatory risks mainly include categories such as environmental institutional and governance management tools and water sanitation and hygiene (WASH) infrastructure.
3Reputation risks primarily refer to factors related to water such as cultural values biodiversity importance media attention and potential conflicts; these risks can have a substantial impact on key indicators like
brand value and market share and are categorized into environmental socioeconomic and other reputational factors.Environmental Social and Preface Sustainable Development Management Winning Progress Winning Economy Winning Environment Winning People Appendix

Evaluate: Identifying Nature-related Dependencies and Impacts
Based on its own production operations and the characteristics of its upstream and downstream value chain Tongwei uses the ENCORE (Explore Natural Capital Opportunities Risks
and Exposures)2 tool to assess the degree of dependency and impact on nature of its photovoltaics and agriculture & animal husbandry segments. The Company creates a materiality
heat map3 to analyze the mutual influence between these factors and its business. The assessment results show that the dependency and impact materiality of the Company’s value
chain on nature are mostly at low to medium levels. For the PV sector potential significant natural dependencies and impacts are mainly related to soil and water functions climate
change and pollutant emissions. For the agriculture and animal husbandry sectors potential significant natural dependencies and impacts are primarily related to soil and water
functions and biological control.
1 Integrated Biodiversity Assessment Tool (IBAT): Developed by the IBAT Alliance (whose members include BirdLife International Conservation International the International Union for Conservation of Nature and
the UN Environment Programme World Conservation Monitoring Centre) this tool integrates three major global authoritative biodiversity databases (the World Database on Protected Areas (WDPA) the World
Database of Key Biodiversity Areas (WDKBA) and the IUCN Red List of Threatened Species) to assess the proximity of project sites to important protected areas for endangered species. https://www.ibat-alli-

2 Encore (Explore Natural Capital Opportunities Risks and Exposures): Jointly developed by the UN Environment Programme World Conservation Monitoring Centre (UNEP-WCMC) and the Natural Capital Finance
Alliance (NCFA) this is a core tool recommended by the Taskforce on Nature-related Financial Disclosures (TNFD). The tool integrates various global nature-related risk information and systematically organizes the
dependencies of different production activities on ecosystem services and their impacts on nature helping businesses identify assess and visualize nature-related risks.
3 The significance of dependency or impact factors corresponding to own operations the upstream value chain and the downstream value chain is divided into five levels: “ Very High (VH) ” “High (H) ” “Medium (M) ”
“Low (L) ” and “Very Low (VL)”; the darker the color the greater the dependency or impact of that value chain segment on the natural ecosystem. A “-” indicates that the dependency or impact factor was not included

Exploring the Application of Low-Carbon Steel to Enhance Product Ecological Benefits
Tongwei has taken the lead in incorporating zinc-aluminum-magnesium coated high-strength steel frames into its module procurement driving deep decarbonization in the supply
chain through material innovation to protect surrounding communities and the ecological environment. This low-carbon steel solution reduces carbon emissions by over 80% per
ton compared to traditional aluminum and improves the material's mechanical properties by 120% to 150% making it suitable for high wind pressure and heavy snow load projects
such as large-scale bases in desert and coastal areas with typhoon resistance. By adopting this low-carbon high-performance steel solution the Company not only achieves
decarbonization of its module products but also sets a replicable green procurement paradigm leading the photovoltaic supply chain to surpass the EU's carbon-related policies
and demonstrating the ecological benefits of renewable energy being “green from the cradle”.Metrics and Targets
Tongwei actively responds to the action targets of the Kunming-Montreal Global Biodiversity Framework and in combination with its business characteristics and ecological risk
assessments has formulated a biodiversity improvement plan for the next five years (–2030) with reference to the TNFD framework establishing phased goals and fully
