About Hoshine Silicon Company Profile Hoshine Silicon Industry Co., Ltd. was invested and established by Ningbo Hoshine Group in 2005 and successfully listed on the main board of the Shanghai Stock Exchange in 2017. It is a company with the most complete sil-icon-based whole industrial chain in the world, the pioneer of the integrated green circular economy model of silicon-based new materials, and the leader of the holistic solution for green energy resources. The Company has set up digital intelligent manufacturing bases in Xinjiang, Zhejiang, Inner Mongolia, Sichuan and other places, and has high-tech re-search and development centers in Shanghai and Hainan. Its businesses mainly cover multiple fields such as energy, silicon metal, silicone, carbon, new materials, third-generation semiconductor silicon carbide (SIC), the whole photovoltaic (PV) industrial chain, and energy storage. Among them, the pro-duction capacities of silicon metal and silicone have ranked first in the world for many consecutive years. The scientific research strength of emerging businesses such as SIC ranks firmly in the first echelon of the industry. The re-lated products are widely used in various fields such as aerospace and military industry, electronic communication, medical and health care, and automobile manufacturing, and its partners are all over the world. Hoshine Silicon focuses on technological innovation, digital and intelligent manufacturing, green development, talent development, process transfor-mation, and organizational upgrading. By leveraging the scale and synergy of a whole silicon-based industrial chain, the Company continues to expand the industrial footprint and enhance technological capabilities. These efforts support the development of the global silicon-based new materials and green
channels platforms Targeted communication Proactive Hoshine Silicon integrates sustainability deeply into corporate strategies. The Company has established a clear and transparent ESG governance framework, while advancing ESG innovation and practical initiatives. These efforts continue to improve the systemization, scientific rigor, and effectiveness of ESG management. Together with stakeholders, we aim to promote a bal- anced and mutually reinforcing relationship between responsible operations and business performance.
In 2025, Hoshine Silicon conducted a double materiality assessment in accordance with the Shanghai Stock Exchange guidelines, including the Guidelines No. 14 of Shanghai Stock Ex- change for Self-Regulation of Listed Companies – Sustainability Report (Trial) and Guidance No. 4 of Shanghai Stock Exchange for Self-Regulation of Listed Companies – Sustainability Re- port Preparation. The Company prioritizes topics with high-impact materiality and discloses topics with financial materiality based on the four-pillar framework. Context analysis of business activities and relationships Reporting Consolidate assessment results into a double Compliant Management Hoshine Silicon adheres to a risk management philosophy of “prudent operations with integrated prevention and control”, with the Board of Directors serving as the core leadership body. The Company has established a three-line defense framework, supported by institutionalized management, regular risk identification and assessment, and audit oversight, to enhance the systematic and effective management of risks and safeguard stable operations.Compliant operations The Company has built a comprehensive compliance management framework that spans strategy, execution, and oversight. This system ensures that all business activities comply with ap- plicable laws, regulations, industry standards, and internal policies, providing a strong foundation for sustainable development.

All production sites are located away from biosphere reserves and op- erate under strict environmental controls, with no material impact on surrounding ecosystems or communities. Meanwhile, we shoulder our responsibilities in ecological conservation by promoting restoration through vegetation planting and the closure of idle landfill areas. We also conduct regular environmental monitoring across plant sites and surrounding areas to ensure ecological safety. Climate Action Hoshine Silicon actively responds to national goals of carbon peaking and carbon neutrality. Guided by the task We regularly update our management regulations, including force on climate-related financial disclosures (TCFD) framework, we integrate climate-related considerations into the Administrative Measures of Carbon Emissions and Energy operations and risk management, leveraging the whole value chain and circular development foundation to opti- Consumption Verification, to guide full-process carbon emis- mize carbon management and advance the low-carbon transition, contributing to high-quality green development sions control and strengthen resilience to extreme weather across the industry. risks. We implement a supervision and reporting mechanism that combines routine internal monitoring with third-party verification, alongside regular reporting and dedicated review Governance meetings, to ensure effective execution and timely progress of climate-related initiatives. In the face of climate change, we have established a three-tier governance structure, covering decision-making, organizational, and execution levels. By defining clear roles, responsibilities, and coordination mechanisms, we en- Strategy hance the scientific rigor of decision-making and the efficiency of execution, ensuring the orderly implementation of climate-related actions and continuous improvement in governance.
