Wiwynn pays close attention to the risks, challenges, and transition opportunities brought about by global climate change and changes in the natural environment, and continues to incorporate related topics into corporate strategies and operational decision-making.
Since 2019, we have been disclosing climate-related information in accordance with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD). By strengthening energy management, increasing the proportion of renewable energy use, and promoting greenhouse gas reduction measures, we actively reduce carbon emissions across our operations and value chain. At the same time, we have gradually deepened the management of natural capital and biodiversity topics. In 2025, we published the "Nature and Biodiversity and No Deforestation Policy" and, for the first time, followed the Taskforce on Nature-related Financial Disclosures (TNFD) recommended methodology to systematically evaluate the dependencies and impacts of operational activities on the natural environment, as well as the correlation between operating sites and ecologically sensitive areas, thereby identifying and disclosing climate- and nature-related risks and opportunities in a more comprehensive manner.

Connection between climate and natural strategy and remuneration system
Besides the senior management, the Company has established the "Operating Procedures for Energy-Saving and Carbon Reduction Reward" for general employees. The procedures include a reward mechanism for proposals on greenhouse gas reduction and energy efficiency enhancement. Through this institutionalized reward mechanism, the Company encourages employees to proactively propose solutions for energy-saving and carbon reduction and energy efficiency improvement, implementing low-carbon actions in daily operations and further reinforcing a company-wide culture of sustainability.
Climate and nature strategy
To address the challenges that climate change and changes in the natural environment may pose to corporate operations, Wiwynn Corporation's Sustainable Development Office collaborates annually with each operating unit to identify and evaluate climate and nature-related risks and opportunities.
The evaluation process refers to the TCFD and TNFD frameworks, international guidelines, topics concerned by internal and external stakeholders, and climate and nature-related topics focused on or disclosed by industry peers and benchmark enterprises. It involves collecting and inventorying relevant information to identify potential risks and opportunities related to the Company's operations.

Processes for identifying and assessing climate risks and opportunities
Wiwynn Corporation identifies and evaluates risks and opportunities in accordance with the Task Force on Climate-related Financial Disclosures (TCFD) recommendations. The identified risks cover transitional risks and physical risks, including existing regulations, emerging regulations, technology, market, reputation, litigation, and acute and chronic climate disasters. Climate opportunities, on the other hand, encompass dimensions such as resource efficiency, energy sources, and products and markets.
On the regulatory side, in addition to incorporating the "Climate Change Response Act," the "Renewable Energy Development Act," and the Low-Carbon City Self-Government Ordinances of various counties and cities, international climate initiatives and the climate policies of the regions where each operating site is located are also considered.
After completing the issue identification, Wiwynn Corporation conducts a risk and opportunity evaluation through a materiality matrix. This evaluation distinguishes between short term (1–3 years), medium term (3–5 years), and long term (more than 5 years) based on the timing and likelihood of impact, and comprehensively assesses both financial and non-financial impact levels.Collection

Processes for identifying and assessing natural risks and opportunities
In managing nature-related risks and opportunities, Wiwynn Corporation refers to the Nature-Related Financial Disclosures (TNFD) framework and implements the LEAP methodology (Locate, Evaluate, Assess, Prepare) to systematically inventory the dependencies and impacts of global operating sites and value chain activities on the natural environment.
By integrating international guidelines for the identification of natural capital risks and opportunities, public databases, and local environmental information, identify material nature-related risks and opportunities, and develop corresponding management strategies, action plans, and follow-up mechanisms to enhance the Company's resilience and decision-making foundation on natural issues.Locate
Through international organizations and local databases in Taiwan, examine whether Wiwynn's global operating sites and the locations of key suppliers are covered by ecologically sensitive hotspots and their level of water risk, as a basis for evaluating nature-related risks and opportunities and developing actions.
➜Evaluate
Conducting dependency and impact factor assessments to analyze the degree of dependence of operating sites on local ecosystem services, and examining the potential impacts that operating and supply chain activities may have on the surrounding ecosystems.
➜Assess
Conducting evaluations of nature-related risks and opportunities, quantifying the impact level of ecologically sensitive hotspots on operating sites, and analyzing the potential operational risks and strategic opportunities they may present.
➜Prepare
Based on the evaluation and assessment results, developing nature-related risk management strategies and action guidelines, and establishing mechanisms for disclosure and follow-up.





Carbon pricing
The Company refers to the carbon taxes, carbon fees, and related carbon pricing systems of the countries/regions where each operating site is located and gradually introduces an internal carbon pricing (ICP) mechanism as a key basis for cross-site carbon reduction management and investment decisions. The Company requires each operating site to evaluate the cost-effectiveness of equipment replacement, process improvement, and energy efficiency enhancement plans based on their operational characteristics and emission structures. This includes internalizing carbon costs into the investment evaluation process to systematically identify high-impact carbon reduction opportunities and enhance the carbon reduction effects of capital expenditures and operational improvements.
Through an internal carbon pricing mechanism, the Company can compare the economics and carbon emission reduction impact of different carbon reduction initiatives at each site using consistent principles. It prioritizes the implementation of improvement measures with clear carbon reduction results and feasibility, and combines energy-saving and carbon reduction projects, renewable energy adoption, and low-carbon technology applications to accelerate carbon reduction actions at global sites. In the future, the Company will continue to review the design and application scope of ICP in accordance with external systems and market trends, strengthening investment evaluation and implementation management at each site, committed to lowering greenhouse gas emissions and enhancing operational resilience.
In 2025, purchased renewable electricity was the primary source of energy use (accounting for 76.57%), followed by purchased non-renewable electricity (accounting for 18.07%). In addition to actively adopting green electricity and purchasing renewable energy certificates, Wiwynn Corporation has also installed rooftop solar panels on newly constructed facilities for on-site self-consumption. At the same time, green building designs and energy-saving measures have been implemented, and a natural gas power generation system has been introduced to gradually build a diversified energy supply framework to disperse energy supply risks and strengthen operational continuity. Wiwynn will continue to optimize its energy mix, promoting low-carbon operations and advancing toward the long-term net-zero goal through enhancing energy efficiency and expanding the use of renewable energy.

Air pollution prevention
In our manufacturing process, only isopropyl alcohol (IPA) is used for cleaning purposes, with no other gas emissions, and the emission levels do not reach statutory regulatory limits. In 2025, VOCs emissions in the Taiwan region totaled 2.65 metric tons.
In addition, based on the Montreal Protocol, ozone-depleting substances (ODS) are classified as hazardous substances and strictly prohibited in materials delivered by the supply chain, and an annual inventory is conducted for Wiwynn's manufacturing site in Taiwan. The Company will continue to conduct reporting and monitoring in accordance with the Air Pollution Control Act to comply with legal and environmental regulations.
