Message from The year marks the ninth year since the United Nations introduced its 17 Sustainable Development Goals and serves as a critical milestone leading up to the expiration of the Paris Agreement signed in 2015. In this year of fluctuating international dynamics and
the Chairman turbulent industry cycles we find ourselves facing an external environment laden with uncertainties. In response to these challenges we
enunciate our "Together to Win" sustainability strategy leveraging our operational resilience . Our sustainability management framework
comprises nine key dimensions built upon three pillars: "Strategy Stewardship Solution". This framework enables us to effectively
respond to sustainability risks while seizing emerging opportunities. Internally we are integrating ESG principles into our daily opera-“ tions. We have announced 13 commitments toward sustainable development and established 20 specific sustainability goals while joining Enhancing Corporate Resilience 10 international sustainable initiatives. As a result we have witnessed continuous improvements in various ESG ratings year by year.through Sustainable Development
Building a New Era of Green and In Tongwei solidified its foundation for development through exceptional governance leading the industry with steady progress.Low-Carbon Economy
Guided by our operation policy of "Focus Execution and Efficiency" we have adopted the compliance guidelines of "Adhere to the Rules
Know and Abide by Rules Protect through Compliance". This approach has established a dynamic and robust corporate governance
ecosystem. We are continuously enhancing our three-tier risk prevention system while deepening our long-term integrity and compliance“ mechanisms to promote agile upgrades in our governance framework. With specialized compliance management modules and multi-chan-nel investor communication strategies in place Tongwei has maintained the highest rating (Class A) for information disclosure from theShanghai Stock Exchange for four consecutive years. We have also cultivated six entities that have achieved ISO 37301 international
certification. Through these efforts we are consistently raising industry standards in governance capacity building while establishing a
modern corporate governance model unique to Tongwei.In Tongwei anchored its vision on carbon neutrality by creating a green paradigm for industrial growth.We remain steadfast in our commitment to sustainable development while driving multidimensional improvements in environmental
performance. Our strategic carbon reduction initiatives have yielded significant results: organizational carbon emissions decreased by 16%
year-on-year and the number of carbon footprint and Environmental Product Declaration (EPD1) certifications increased by 26 items. The
implementation of our environmental management system has resulted in a systematic reduction of over 20% in emissions from wastewa-
ter exhaust gas and solid waste pollutants. Additionally renewable energy consumption has surpassed 23.965 million megawatt-hours
(MWh) positioning the proportion of clean energy utilization at an industry-leading level. Faced with the pressing challenge of global
climate resilience construction Tongwei is accelerating its commitment to low-carbon development. Grounded in our climate ambitions
for 2030 and informed by scenario-based climate analyses as benchmarks we have proposed a comprehensive value-chain carbon
neutrality plan that establishes a model closed-loop system integrating zero-carbon manufacturing with green products and climate
governance—providing an exemplary Chinese solution for global enterprises addressing climate change.

In Tongwei forged deep connections with both employees and society fostering a widespread humanistic influence.Tongwei has consistently maintained a harmonious interaction with its employees and society placing significant emphasis on safeguarding employees' rights and interests. We
have deeply embedded the United Nations Women's Empowerment Principles (WEPs) to foster an equitable and inclusive workplace environment. By integrating international
standards such as ISO 37301 and EcoVadis Tongwei has established a more comprehensive and rigorous labor compliance management mechanism. Our commitment to building
a high-standard sustainable supply chain is steadfast. Leveraging the strengths of our integrated PV industry chain we have obtained EPD1 certifications and carbon footprint
certifications and enhanced our traceability management capabilities. These efforts enable us to provide society with green low-carbon and responsible products across their“entire lifecycle. Notably Tongwei has achieved a milestone as the first enterprise to successfully pass the TüV Rheinland traceability audit in one attempt receiving all A-grade or above evaluation results. Looking externally Tongwei warmly embraces the voices and suggestions from all sectors of society adhering to the principle of "Build Together GovernTogether and Share Together". We actively engage in social initiatives such as charitable donations rural revitalization and science popularization demonstrating our dedication
to spreading positive societal impact through concrete actions.In Tongwei reaffirmed its commitment to sustainable development while further connecting with international platforms.This marked a significant y“ear for our company as we made our fifth appearance at the United Nations Climate Change Conference (COP 29) showcasing our practical achieve-ments and sharing the story of climate actions from China and Tongwei with the global community. During China's annual National People's Congress (NPC) and Chinese People'sPolitical Consultative Conference (CPPCC) Sessions Chairman Liu Hanyuan of Tongwei Group Board of Directors submitted important proposals focused on establishing a power
grid emission factor database and enhancing the green power trading mechanism. He expressed his hope that by calculating regional power grid carbon emission factors which
can effectively support Chinese products in accessing global markets. Currently we have successfully achieved the large-scale "going global" of our battery and component
products continuously advancing high-quality products into the international market. This effort significantly contributes to the achievement of national and global carbon peaking
and neutrality goals. As we celebrate the 20th anniversary of the ESG concept Tongwei stands out as the only PV main material manufacturing enterprise recognized as one of the
"20 Best Cases in 20 Years" by UNGC. This accolade underscores our commitment to sustainable practices on an international level.The deadline for achieving the Sustainable Development Goals (SDGs) by 2030 is rapidly approaching. The United Nations' assessment report indicates that global progress
toward the 17 SDGs is lagging with only 16% of the targets currently on track to be met by 2030. Additionally the 1.5°C temperature control target outlined in the Paris Agreement
faces substantial challenges. The path toward global sustainable development remains long and challenging. As we reflect on a year marked by fluctuations Tongwei will steadfast-
ly uphold our commitment to sustainable development principles. We will continue to deepen technological innovation enhance corporate governance and expand our presence
in international markets. With a reliable image we will take on greater social responsibilities and collaborate closely with all our partners to create a brighter future together!｜Environmental Social Sustainable Together to Consolidate Together to Advance Together to Leverage Together to Protect the Together to Strengthen Development Stewardship: Stable and R&D: Cutting-Edge Intelligent Solutions: Environment: Green and Collaboration: Diverse and

2.Commitment System
Tongwei adheres to the principle of "Striving for Excellence and Contributing to Society". We actively support and respond to the United Nations Sustainable Development Goals (SDGs)
while placing equal emphasis on business value and social responsibility. Our commitment is to conduct business with high ethical standards. Moreover we actively advocate for collabo-
ration with suppliers and partners to jointly advance sustainable development. We embody our sustainable development mission through the principles of "build together" "govern
together" and "share together" for a sustainable and better life.To standardize our corporate sustainability pathway and demonstrate our commitment to sustainability Tongwei has identified several key areas in which we have established a sustain-
ability commitment system. As of the end of Tongwei has publicly released 13 sustainability commitments and policies:

3. Metrics and Targets System
The successful implementation of the sustainable development strategy requires not only the guidance of our mission and the support of policies and commitments but also a
clear system of goals to serve as a roadmap. Under the three main dimensions of environment society and governance we have proposed 20 goals across short- medium-
and long-term horizons to form the sustainable development goal system of Tongwei.Short-term Medium-term Long-term

To ensure the effectiveness and relevance of this goal system Tongwei conducts regular reviews. In response to changes in domestic and international policies regulatory require-
ments and industry developments we continuously evaluate track adjust and update our sustainable development goals to ensure alignment with both our strategic direction and
the external environment. Additionally we integrate long-term sustainable development goals into both internal policies and external documentation to institutionalize goal manage-
ment. In with the collective efforts of all members of Tongwei we successfully achieved 4 sustainable development goals.Environmental Water conservation goal for : 4.5259 million tons Completed

To standardize sustainable information disclosure and target management at Tongwei Co. Ltd. and its business entities the ESG Management Committee has taken the lead in estab-
lishing an ESG indicator system and compiling the Manual for Using Tongwei Co. Ltd.'s Environmental Social and Governance (ESG) Indicator System. This manual references multiple
domestic and international disclosure frameworks establishes more than 300 sustainable development indicators and is updated annually to align with evolving policies and industry
trends thereby ensuring robust effectiveness in advancing sustainable development goals.｜Environmental Social Sustainable Together to Consolidate Together to Advance Together to Leverage Together to Protect the Together to Strengthen Development Stewardship: Stable and R&D: Cutting-Edge Intelligent Solutions: Environment: Green and Collaboration: Diverse and

4.Governance System
The sustainable development governance system serves as a critical support for stewardship enabling the Company to swiftly adapt to changes in external trends accurately grasp
the latest developments in sustainability and ensure timely responses to stakeholder needs. The Company adheres to the principles of "dynamic identification rapid response and
resilient development" as its operational guidelines and constructs a sustainable development governance system centered around its governance structure.Tongwei has established and refined a three-tier sustainable development governance framework comprising "decision-making management execution". The
Board of Directors along with its subordinate Strategic Sustainable Development Committee serves as the highest decision-making body. The ESG Management Committee and
ESG Management Working Group are tasked with coordinated management. Additionally the Company integrates operation management functional departments and business
segments into the sustainable development governance framework. This includes identifying risks and opportunities associated with specific sustainability issues as part of their
routine operations. This approach fosters a governance mechanism that facilitates vertical collaboration from top to bottom and from bottom to top while establishing a compre-
hensive risk and impact management layout that spans the entire organization. By promoting cross-sectoral and cross-functional collaboration horizontally we ensure that the
principles of sustainable development are effectively implemented across all levels and business areas thereby laying a solid foundation for stable operations and resilient growth.Decision- Board of Directors Strategic & Sustainable Development Committee Core Operation Management

Tongwei adheres to the principle of "dynamic identification rapid response and resilient development" by implementing a rolling management mechanism for sustainable develop-
ment. This approach allows for the dynamic identification and control of risks and opportunities throughout production and operational processes. The Company regularly
convenes meetings across various departments and business segments focused on analyzing sustainability challenges and improvements. Periodic reports are made to the Board

Drawing on industry characteristics value chain positioning and actual development conditions Tongwei has established a systematic mechanism for identifying and assessing
materiality issues. This mechanism precisely addresses the concerns of stakeholders and provides a scientific basis for the Company's risk and opportunity management.In the Company further advanced the organic integration of financial management and sustainable disclosure and carried out financial materiality assessment for the first time.By organizing middle and senior management personnel from functional departments such as finance investment procurement and supervision and audit and employing a combi-
nation of quantitative assessment and qualitative analysis methods key issues that may affect the Company's financial situation were identified. This measure not only ensures that
sustainable issue management does not harm financial performance but also promotes the integration of sustainable considerations into the management decision-making system.Evaluators 6 financial materiality issues

Responsible Mineral Procurement
We have formulated and issued the Tongwei Co. Ltd. Conflict Minerals Commitment and Policy to safeguard labor and human rights healthcare and the environment in mineral-producing
regions aiming to strengthen controversial sourcing practices of conflict minerals. Tongwei pledges strict compliance with the UN Global Compact OECD's Due Diligence Guidance for
Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas the Responsible Minerals Initiative (RMI) and further international regulations. We prioritize responsible
sourcing of minerals like tantalum tin tungsten and gold (3TG) for our products ensuring all mineral inputs are acquired both legally and ethically.The Company has established a conflict minerals management mechanism. Every supplier must sign the Supplier Conflict Minerals Commitment and Declaration of Tongwei Co. Ltd. before
admission and conflict-minerals criteria are embedded in the Supplier ESG Audit Form to conduct supplier due diligence. Moreover first-tier suppliers are required to guarantee their
non-involvement in transactions of conflict materials while also imparting the principles of responsible mineral procurement to their respective suppliers in higher tiers to reinforce
compliance throughout the entire supply chain.Meanwhile Tongwei has implemented an oversight and reporting channel administered by its supervision department. The department's contact information is publicly available on the
corporate website in the Supplier Compliance Commitment and in the Supplier Guidelines. Suppliers and stakeholders are encouraged to monitor our responsible mineral sourcing
management and reinforce its transparency.In we mandated that all suppliers potentially exposed to conflict minerals sign the Tongwei Supplier Conflict Minerals Declaration and Commitment achieving a 100% signing rate.Follow-up due diligence confirmed that none of our suppliers procure conflict minerals achieving a 100% conflict-free supplier ratio. Tongwei will require primary conflict metal material
suppliers to conduct self-assessments in line with RMI guidelines and cross-verify results using the Conflict Minerals Reporting Template (CMRT) or other tools.Sustainable Together to Consolidate Together to Advance Together to Leverage Together to Protect the Together to Strengthen ｜Environmental Social Preface Development Stewardship: Stable and R&D: Cutting-Edge Intelligent Solutions: Environment: Green and Collaboration: Diverse and and Governance Report Appendix 102Management Robust Operation Technology Innovation Responsible Procurement Low-Carbon Development Inclusive Partnership

10. Reasons for not including other categories in Scope 3 in the calculation: 1. Regarding the carbon emissions from product use silicon products need further processing before they can be used as end products. The
use phase of solar cells and PV module products varies depending on specific working conditions and usage methods making it difficult to accurately quantify. 2. For the carbon emissions in the category at the end of
the product life cycle because there is currently no average data on the end of the product life cycle in the industry it is difficult to accurately quantify. 3. Regarding other categories such as downstream leased assets

Emissions for Enterprises in the Cement Industry (CETS-AG-02.01-V01-).
14. The main reasons for the change in Scope 1 greenhouse gas emissions in : To be consistent with the 2023 accounting methodology fugitive emissions continue to be calculated using the charging method. The newly built
factories put into operation in led to an increase in Scope 1 greenhouse gas emissions due to a relatively large purchase volume of refrigerants.
15. The market-based Scope 2 greenhouse gas emissions are calculated in accordance with The Notice by the National Development and Reform Commission the Ministry of Finance and the National Energy Administration of Effectively

ed under the policy scenario representing the company’s internal accounting results .
16. The location-based Scope 2 greenhouse gas emissions are calculated based on the 2022 national average carbon dioxide emission factor of electricity as published in The Notice by the Ministry of Ecology and Environment and the
National Bureau of Statistics on the Release of the 2022 Carbon Dioxide Emission Factor of Electricity ().
17. The main reason for the change in Scope 2 greenhouse gas emissions in : The commissioning of newly built factories led to an increase in electricity consumption.
18. The location-based Scope 2 greenhouse gas emissions (regional grid) are calculated based on the 2022 regional average carbon dioxide emission factor of electricity as published in The Notice by the Ministry of Ecology and

Completed in November with full environmental protection compliance Yongxiang's Phase I High-Purity Polysilicon Project features an advanced wastewater classification and
recycling system incorporating industry best practices. The project features a comprehensive wastewater treatment infrastructure including one filtered wastewater treatment system for
cleaning and rinsing purposes one 400 m3/h recycled water treatment system (soft water station) and one centralized wastewater treatment plant equipped with two integrated wastewa-
ter treatment lines (total capacity 240 m3/h comprising one 120 m3/h low-chlorine wastewater treatment station and one 120 m3/h chlorine-containing wastewater treatment station) and
one 50 m3/h high-salinity wastewater treatment unit. This integrated system has significantly improved wastewater treatment efficiency while maximizing water resource recycling.Case Groundwater pollution prevention and control at Tongwei Solar Technology's Nantong Production Base
In Tonwei Solar Technology implemented a rigorous groundwater protection program at its Nantong production base adopting a dual prevention strategy to minimize potential
impacts on groundwater and soil.For source control Tongwei Solar Technology implemented anti-seepage treatments for all water supply and drainage pipelines in the project completely preventing wastewater infiltra-
tion and eliminating any "leakage spillage dripping or seepage" of sewage thereby ensuring the normal operation of the wastewater treatment system. Notably the project applied a
visual management approach by routing wastewater transfer pipelines above ground where possible enabling immediate leak detection and prompt remediation to avoid potential
groundwater contamination from buried pipe failures.For end control Tongwei Solar Technology has adopted zoned anti-seepage measures and pollutant collection strategies in areas within the facility that are prone to contamination.Anti-seepage treatment has been implemented in locations such as chemical storage areas and production workshops to prevent contaminants from seeping underground and to collect
and treat any pollutants accumulating on the surface in a centralized manner thereby avoiding contamination of groundwater.Tongwei’s Emission Reduction Performance of Wastewater and Pollutants

Pollution Caused by Solid Wastes and the Standard for Pollution Control on Hazardous Waste Storage (GB 18597-2023) and formulate comprehensive management systems such as
the Solid Waste Management System and the Hazardous Waste Disposal Management System. For non-hazardous waste we conduct systematic classification collection and storage.Hazardous waste is collected and stored separately in dedicated storage facilities before being regularly transported to licensed treatment providers. We actively explore recycling
solutions for high-value non-hazardous waste to maximize resource recovery. These integrated approaches significantly reduce the environmental impact on surrounding
communities while promoting our circular economy development.In Tongwei Solar (Hefei) was awarded the "Zero-Waste Factory" title by Hefei authorities in recognition of our outstanding performance in waste management and resource
