Reported by: Thitirin Thepsiri and Natthawut Foithong Reviewed by: Saroj Ruangsakulraj2 Greenhouse Gas Inventory Report (ISO 14064-1) Introduction The global financial crisis is causing massive economic upheaval, but with the world's governments working together, recovery is now in sight. Yet the threat posed by global warming still requires a major breakthrough in international negotiations and a change in modern lifestyles to slow the rate of warming and avert an ecological catastrophe. With our corporate mission of "To provide innovative, clean and efficient energy solutions for a better tomorrow", DET strive to do our utmost to help slow global warming and reduce our environmental impact and also believe in fulfilling Delta's CSR goals through sound corporate governance, balancing stakeholder interests and social participation. Responding to climate change is not only a corporation's social responsibility. How to respond to the threat it poses; and take advantage of the opportunities it offers; is something that businesses must look at seriously in their corporate strategies. Carbon emissions reporting becoming an important topic, there is an increasing move towards greenhouse emissions reporting and disclosure. DET is looking towards best practice in the area of sustainability reporting. Sometimes the information is included in Annual Reports or in annual Sustainability and Corporate Responsibility reports. The format and composition of the information varies widely. Greenhouse Gas report illustrates for a typical company the strategy, targets, performance, and benchmarking of how the company is working to reduce its impact on and adapt to climate change. Clearly, in order to produce reliable information for such reporting, and to monitor emissions performance and management actions to achieve reductions during the year, companies will need to consider carefully processes, systems, controls and internal reporting requirements.3 Greenhouse Gas Inventory Report (ISO 14064-1) Contents 1.

Delta Electronics (Thailand) Public Company Limited including other sites in Southeast Asia and Oceania (hereafter DET) had approximately 21,765 workers during the 2025 year.6 Greenhouse Gas Inventory Report (ISO 14064-1) 2. GHG Management 2.1 Guideline of the report This emissions inventory report has been prepared and written in accordance with the principles set out by the International Standards Organization (ISO) for the quantification and reporting of Greenhouse Gas Emissions and Removals (ISO14064-1). 2.2 Report Principle and Criteria This report is prepared primarily in accordance with the requirements of ISO 14064-1:2018. 2.3 Reporting Period and Responsibility / Validity Period 2.3.1 Reporting Scope and Validity The scope of this report covers all greenhouse gas emissions generated within the organizational and operational boundaries of DET during the year 2025. This report remains applicable until the issuance of the next annual greenhouse gas inventory report. The reporting period is from 2025/01/01 to 2025/12/31. For clarity, the companies included in this report are detailed in Table 2.3.1 below. Table 2.3.1 List of Covered Companies No. Company Name 1 Delta Electronics (Thailand) PCL. 2 Delta Green Industrial (Thailand) Co., Ltd. 3 Eltek Power Co., Ltd. 4 Delta Electronics (Australia) Pty., Ltd. 5 March Networks (Australia) Pty., Ltd. 6 Delta Electronics (Vietnam) Co., Ltd. 7 Delta Electronics Solutions (Malaysia) Sdn. Bhd., 8 Universal Instruments Corporation 9 ELTEK POWER INCORPORATED 10 Delta Electronics Int’l (Singapore) Pte., Ltd. 11 PT Delta Electronics Indonesia 2.3.2 Inventory Preparation Timeline This report is prepared annually. The greenhouse gas inventory process for the previous year is initiated in January of each year, together with the preparation of the report contents. The report summarizes the Company’s greenhouse gas emissions for the preceding reporting year and remains applicable until the completion and issuance of the subsequent annual report.7 Greenhouse Gas Inventory Report (ISO 14064-1) 2.3.3 Internal Verification and Publication The inventory scope of this report is limited to the total greenhouse gas emissions within the Company’s operational boundaries. In the event of changes to the Company’s organizational structure or operational boundaries, the report will be revised accordingly and reissued to reflect the updated conditions. Upon completion, this report undergoes an annual internal verification process. Any identified deficiencies are corrected prior to finalization. After internal approval, the report is officially issued and published on the Company’s website. This report becomes effective upon issuance and remains valid until it is revised or withdrawn. 2.4 Purpose of Report Preparation - To clearly disclose information related to the Company’s greenhouse gas inventory activities, thereby ensuring transparency. - To respond to international environmental trends and customer demands, the Company implements its environmental policy by conducting greenhouse gas inventories and internal verifications. This demonstrates the Company's performance in greenhouse gas management and enhances corporate image. - To properly document the Company’s greenhouse gas emissions inventory, in order to facilitate future verification and validation requirements, as well as to serve as supporting evidence for potential participation in domestic or international emissions trading schemes. 2.5 Base Year Setting 2.5.1 Explanation of Base Year Selection Due to the differences in emission sources among sites of categories 3 to 6, as well as the varying implementation times at each site, the base year for each site is set as the year of its initial inventory: 2.5.2 Base Year Set the base year for SBTi: 2°C SBT target Base-year Greenhouse Gas Inventory is annually thereafter, DET shall report the inventory of the preceding calendar year. DET has chosen the set base year for this report in 2014, which spans from January 1st , 2014 to December 31st , 2014, in the following manner: - GHG Scope 1 (tCO2e) : 823.56 - GHG Scope 2 (tCO2e) – Location based : 37,662.19 - Total GHG Scope1 and 2 (tCO2e) – Location based : 38,485.75
