Message from the President Commissioner Bambang Permadi Soemantri Brodjonegoro President Commissioner/Independent Commissioner We view positively the Telkom Group's sustainability performance which has consistently experienced development, as evidenced by various awards and achievements in environmental, social and governance aspects. " Message from the President Commissioner Introduction 10 PT TELKOM INDONESIA (PERSERO) TBK About Sustainability Report Message from the President Commissioner Message from the President Director

Esteemed stakeholders, We begin by expressing gratitude to God Almighty for Telkom's ability to sustain its performance and strengthen its foundation for long-term business growth throughout 2024. This year presented various challenges, including macroeconomic conditions, competitive dynamics, technological advancements, and sustainability issues. Recognizing the increasing relevance of sustainability to the telecommunications industry, Telkom has made significant efforts to enhance both operational and financial performance, thereby generating positive impacts and long-term value for all stakeholders. Throughout 2024, we have observed the Board of Directors concrete steps in reinforcing sustainability strategies and initiatives across the Telkom Group. The leadership of the Board of Directors, supported by all subsidiaries, has effectively synchronized sustainability initiatives across the organization. In 2024, Telkom established the Telkom Group Sustainability Strategy and 2030 Targets as a strategic roadmap to integrate sustainability measures across environmental, social, and governance dimensions. Telkom has also demonstrated its commitment to transparency and accountability by engaging an independent external party, TUV Rheinland Indonesia, to conduct external assurance on the 2024 Sustainability Report. This step reinforces the company's dedication to enhancing the quality and credibility of its sustainability disclosures. The Telkom Group's sustainability performance has shown continuous improvement, as evidenced by various achievements in environmental, social, and governance (ESG) aspects. Notably, Telkom has received multiple awards, including Outstanding Leadership in Sustainability (CNBC Indonesia), first place in MSEs and SOE House Development (BCOMSS Ministry of SOEs), Integrated Sustainability Initiatives – Education, Decent Work and Technology (IDX Channel), Gender-Inclusive Workplace (UN Indonesia WEPs), and Best Companies to Work for and Sustainable Workplace (HR Asia). Additionally, Telkom's ESG ratings have improved, with its Sustainalytics rating advancing from 27.1 to 25.6 (Medium Risk), its ESG rating from BPKP increasing from 74.02 (Fair) to 91.23 (Very Good), and earned a B rating from the Carbon Disclosure Project (CDP) for climate change readiness. This achievement continues to encourage Telkom’s spirit and consistency in improving sustainability performance, not only focusing on increasing the number of awards and rating numbers but more importantly, on enhancing the quality of company management that impacts all aspects of sustainability. As part of improving the quality of the company's management, we note that Telkom needs to continue to mitigate global risks and challenges that have the potential to disrupt Telkom Group's business and service operations, including cybersecurity risks, extreme weather, and disasters due to climate change, as well as the quality of human resources in line with the Company's digital transformation. The development of products and equitable distribution of telecommunication services through the use of technology and innovation needs to be carried out by prioritizing aspects of usefulness and responsibility, while still taking into account the investment value and reasonable price so that Telkom can maintain its sustainability in the long term. In facing these challenges, it is essential to be supported by a strong governance foundation so that every strategic and operational step taken not only drives business growth but also contributes to long-term sustainability and value creation for all Telkom Group stakeholders. Strengthening governance entails enforcing discipline, including in the areas of rewards and sanctions, reinforcing integrity and ethics, and fostering a corporate culture that supports governance principles. Finally, on behalf of the Board of Commissioners, I extend my gratitude for the support in implementing sustainability practices in the Telkom Group and hope to strengthen collaboration and synergy to continue the partnership and realize a sustainable future. In addition, as part of our gratitude, we would like to thank the Board of Directors, partners, and all Telkom stakeholders for their contributions in realizing sustainable growth.

Message from the President Director [POJK. D-1] Ririek Adriansyah President Director Telkom's commitment is demonstrated through strategic actions undertaken in 2024, where the company has achieved several key milestones in its sustainability journey. " Message from the President Director [POJK. D-1] Introduction 12 PT TELKOM INDONESIA (PERSERO) TBK About Sustainability Report Message from the President Commissioner Message from the President Director

Esteemed stakeholders, In recent years, the global telecommunications industry has been faced with various sustainability opportunities and challenges, including increasing demand for digital services, artificial intelligence-based innovation opportunities, and increasingly real impacts of climate change. Amid this dynamic, Telkom remains committed to realizing sustainable business growth and creating added value for all stakeholders. An independent external party has been appointed to assure the 2024 Sustainability Report, which has been declared compliant with AA1000AP Accountability Principles, Type 2 Moderate Assurance Level according to AA1000AS v3 standards, and follows the reporting requirements referenced in the 2021 GRI.

Telkom also updated its sustainability targets and strategies that highlight the GoZero% program as a form of our seriousness to make sustainable improvements and respond to the inputs and expectations of key stakeholders. Telkom's sustainability strategy is aligned with the Sustainable Development Goals and includes three main pillars of sustainability. The Save Our Planet pillar reflects Telkom's commitment to reducing the environmental impacts of business operations, particularly in areas that have significant impact, such as emissions and waste management. In 2024, Telkom Group initiated the calculation of emissions for all scopes (scopes 1,2, and 3), where scope 3 covers 9 categories, and has set 2023 as the base year in determining the emission reduction target. Greenhouse gas (GHG) emissions were calculated using the GHG Protocol standard, and verification of scope 1 and 2 GHG emissions were verified by an independent party using the ISO 14064-1:2018 standard. This initiative aims to enhance the confidence and credibility of the GHG emissions as a basis for determining the strategy to achieve Net Zero 2060 and preparation to fulfill IFRS S2 standards. The total GHG emissions of Telkom Group scopes 1, 2, and 3 is 2.417.474 tons of CO2e, with 84% of emissions coming from scope 2. Scope 2 emissions rose by 2.8% due to the expansion of Telkomsel's BTS infrastructure, while scope 1 emissions decreased by 2% as a result of reduced operational vehicle use, and scope 3 emissions decreased by 8.1% owing to capital expenditure efficiency initiatives. In terms of energy management, Telkom Group has incorporated renewable energy sources, including solar PV and microhydro, into its energy mix. The Group also utilizes Electric Vehicles (EVs) for operational purposes and pursues energy efficiency through procurement and upgrades of environmentally friendly equipment. In addition, Telkom Group managed to reduce the total office waste generated by 6,387 tons and divert as much as 176,046 kg or 80% of fiber optic cable waste from disposal. The diverted fiber optic waste can be reused to support customer service. Telkom Group has also advanced biodiversity conservation efforts and enhanced the carrying capacity of ecosystems, including mangrove planting, forest revegetation, and coral reef transplantation. The Empower Our People pillar signifies Telkom Group's dedication to empowering employees, customers, and the community through the creation of an inclusive digital ecosystem as the foundation for capability development and sustainable innovation. Throughout 2024, 22% of managerial positions in Telkom Group are filled by female employees, supported by initiatives at Telkom that promote gender equality in the work environment. For digital skills development, the Digital Talent program has upskilled 20.6% of Telkom's digital talents through Telkom Athon and various other digital trainings. Telkom also prioritizes occupational safety by implementing an occupational health and safety management system (SMK3) aligned with international standards, such as ISO 45001, while ensuring compliance with applicable national regulations. From a customer perspective, Telkom Group is focused on enhancing service quality by prioritizing customer satisfaction. This is evidenced by an increase in the Net Promoter Score (NPS) to 58 points from the previous year, placing the company in the "Excellent" category based on Bain & Company’s evaluation. This improvement is driven by enhanced service quality and more attractive promotional strategies. Telkom Group continues to play an active role in expanding digital access across Indonesia while accelerating infrastructure development 2024 SUSTAINABILITY REPORT 13 2024 Sustainability Reporting Responsibilities Sustainability Overview in 2024 Awards in 2024 About Telkom

Performance Evaluation of the Board of Commissioners and Board of Directors Telkom implements a self-assessment policy for evaluating the performance of the Board of Commissioners. The Nomination and Remuneration Committee (KNR) conducts the assessment based on collegial key performance indicators (KPIs), which are derived from the core responsibilities of the Board of Commissioners. These responsibilities include supervising the Company's management policies and operations executed by the Board of Directors, providing guidance, and ensuring compliance with the Company's Long-Term Plan (RJPP), Annual Work Plan and Budget (RKAP), Corporate Strategic Scenario (CSS), and applicable laws and regulations. The performance evaluation results are subsequently reported to Shareholders at the GMS. Remuneration Policy The remuneration framework for Telkom's Board of Commissioners and Board of Directors is established in accordance with the Regulation of the Minister of State-Owned Enterprises Number PER-3/MBU/03/2023 concerning SOE Organs and Human Resources. This is further reinforced by the Board of Commissioners' Decree Number 03/KEP/DK/2024 regarding remuneration entitlements. Unlike the evaluation of Board of Commissioners, the Board of Directors' performance evaluation is conducted through a self-assessment by each member, measuring both individual and collegial KPI achievements. These results are reviewed annually by a Public Accounting Firm that audits Telkom’s financial statements. The achievement report is presented to the Board of Commissioners and the Ministry of SOEs. The Public Accounting Firm review encompasses the methodology and consistency of KPI assessments for the Board of Directors. In 2024, the review confirmed no inconsistencies. [GRI 2-18] 1.

[GRI 2-20] In 2023, the Ministry of SOEs issued Regulation Number PER-3/ MBU/03/2023 concerning SOE Organs and Human Resources (Permen 3 BUMN). Telkom has confirmed the implementation of this regulation through the GMS resolution for the 2022 financial year. One of the provisions under Permen 3 BUMN pertains to the suspension of partial payments of tantiem for the Board of Directors and Board of Commissioners. Telkom also enforces a clawback policy, which mandates the recovery of incentive-based compensation from current and former Board members if the Company is required to restate financial statements submitted to the United States Securities and Exchange Commission (SEC) under the Exchange Act. This restatement is necessary to correct material errors in previously issued financial statements or to address errors that could result in material misrepresentation if not rectified in the current reporting period. The Ministry of SOEs has incorporated this policy into the tantiem framework, stipulating a three-year suspension of tantiem payments for the Board of Commissioners and Board of Directors.

The methodology for identifying these risks and opportunities is detailed in the 2023 Climate Risk Report. Physical [R] risks: 1. Acute: • [R] Increased intensity and frequency of extreme rainfall that may cause flooding. • [R] Increased intensity and frequency of cyclones that may disrupt company operations. • [R] Increased frequency of forest fires that may disrupt company operations. • [R] Increased heatwave frequency that may disrupt company operations. 2. Chronic: • [R] Rising temperatures, leading to asset damage, infrastructure degradation, and decreased productivity of field workers. • [R] Increased rainfall that may cause flood. • [R] Rising sea levels that may lead to infrastructure damage. • [R] Increased drought that may disrupt company operations. Transition risks [R] and opportunities [O]: 1. Policy and legal: [R/O] An increase in carbon prices driven by increasingly stringent carbon tax regulations to encourage decarbonization. 2. Technology: [O] Use of renewable energy to reduce emissions and optimize operational costs; [O] Technological developments to drive energy efficiency. 3. Market: [R/O] Increased energy and electricity costs from rising supply chain energy tariffs; [R/O] Increasing demand for ecological/climate-friendly products from consumers. 4. Reputation: [R/O] Reputational impact based on company’s success or inability to meet stakeholder expectations of climate action. Climate scenario analysis In 2023, Telkom conducted a climate scenario analysis focusing on extreme rainfall and temperature rise to assess exposure risks to land and building assets. The analysis employed Shared Socioeconomic Pathways (SSP) scenarios SSP1-2.6 and SSP5- 8.5 from the Intergovernmental Panel on Climate Change (IPCC) for physical climate risks and utilized the Network for Greening the Financial System (NGFS) Current Policy and Net Zero scenarios for transition risks. A subsequent analysis in 2024 expanded asset mapping to identify locations in disaster-prone areas, referencing the 2023 Indonesian Disaster Risk Index issued by the National Disaster Management Agency (BNPB). This enhanced analysis supports Telkom prioritization of at-risk areas for adaptation measures. The results of this process are shown in the two images below.

The mapping of these locations serves to assist Telkom in determining priority areas in the planning and implementation of the company's adaptation efforts. The highest number of exposed assets is consistently represented by assets on Java and Sumatra, followed by Sulawesi. Going forward, Telkom will use the results of this analysis as input to strengthen its business resilience. Telkom also assesses transition risks, which includes 1) carbon pricing, 2) renewable energy adoption, 3) increasing energy costs, 4) reputational impact in meeting stakeholder’s expectations. This analysis uses the NGFS Net Zero and Current Policy scenarios and aims to identify the exposure from carbon pricing enforcement, solar panel investment costs, and energy costs. The findings indicate potential exposure to carbon costs of approximately Rp2.7 trillion by 2050 under the NGFS Net Zero scenario. Additionally, solar panel investment costs are projected to decrease from Rp229 billion in 2030 to Rp140 billion in 2050 due to global low-carbon transition efforts. Energy costs, including electricity and fuel, are expected to grow at a compound annual rate of 4.4–4.5% until 2050 under the same scenario. The full assessment results and methodology are available in the 2023 Climate Risk Report. Telkom has established a strategy to enhance business resilience to climate risks, including setting key metrics and targets, with GHG emissions as a main metric which will be continuously monitored. Telkom’s target includes Scope 1 and 2 emissions reduction by 20% by 2030, compared to the 2023 base year, and achieve net zero for Scope 1 and 2 emissions by 2030. In responding to physical risks, Telkom has implemented various mitigation measures, such as upgrading building infrastructure to improve flood resilience by incorporating climate projections into infrastructure installation and new building construction. The company also conducts regular flood risk assessments, particularly for critical assets like Automatic Telephone Centers (STO) and outdoor equipment. In addition, the company ensures optimal cooling systems in buildings to prevent overheating and equipment damage due to high temperatures, while also maintaining field worker productivity through the Finance & Asset Operation Unit. Telkom has established flood disaster response guidelines and a Business Continuity Management system in place since 2010, applicable across all organizational levels. It has also formed a Crisis Management Team responsible for ensuring effective emergency response and ongoing monitoring to prevent secondary incident impacts. Telkom is also certified with ISO 22301:2019 for its Business Continuity Management System (BCMS), ensuring operational continuity and mitigation of business disruption risks. To anticipate flood risks, Telkom has also provided flood mitigation equipment and facilities, such as water pumps, particularly in areas identified as flood prone. These measures have helped minimize the impact of past flooding events in Telkom Group, during which production tools and network equipment were secured and no casualties occurred. In cases where floods cause power outages, the affected telecommunications network remains operational through the activation of backup generators. In addition to implementing disaster management systems, Telkom also considers the results of climate risk assessments when making decisions related to planning, construction, and facility upgrades. Moving forward, Telkom aims to continue taking proactive steps in climate adaptation, including building partnerships with research institutions, government agencies, and other third parties.

Environmental Costs Environmental Performance 2024 SUSTAINABILITY REPORT 63 Resource Management Management Approach Resource management at Telkom is governed by the Regulation of the Board of Directors on sustainability governance. This formal policy serves as a guideline for the governance of both resource management and climate change and energy management. Telkom has set a 2030 target to minimize environmental impact by diverting office and fiber optic cable waste from disposal. Telkom has conducted annual performance monitoring and evaluation through recording and responsible waste management. [GRI 3-3] Waste Management Telkom’s core operations rely on material resources, such as communication support equipment, to ensure the seamless delivery of services to customers. In the process, these activities produce waste that requires responsible management following sustainability principles. Telkom has implemented office waste sorting through trash bin facilities spread throughout Telkom office buildings. In the future, Telkom will continue to strive to enrich its responsible waste management and documentation initiatives. [POJK F.14] E-waste management One of the wastes generated by Telkom Group's operational activities is fiber optic cable waste. Telkom targets a minimum of 70% of fiber optic cable waste to be diverted from final disposal by 2030. Until 2024, it is recorded that the amount of fiber optic cable waste diverted from final disposal by TIF is 176,046 kg or 80% of the total cable waste. This figure is calculated by comparing the amount of cable waste that can and has been reused to the cable waste collected by TIF. The procedure for sorting and recycling fiber optic cable waste carried out by TIF involves cooperation with third parties. Partners involved are including Alfa-spark, Haidong, KSP, Pandawa, Semitech, Tio Putra Sulung, Yifeng, TMS, Mukti Mandiri Lestari, Griyo Asri 45, Airmas Tanjung, Devina Mandiri Sejahtera, Margo Mulyo Logam, and Triado Jayano Abadi. In addition, Telkom Group also separates e-waste from non-electronic waste. This e-waste generally comes from outdated and unused devices. Telkom has also implemented product end-of-life management for IT hardware such as computers, servers, and routers, which are included in Customer Premises Equipment (CPE) through its subsidiaries, namely PINS and Telkomsel. The collected CPE devices are then separated by category based on the treatment required. The categories are ready-to-use refurbished devices, devices as a backup for employee work tools, devices sold to third parties, and devices to be written off. In addition, Telkom's subsidiary, Telkomsel, has also carried out modem waste management. By 2024, a total of 149,433 units of modem devices (including ONT or Optical Network Terminals and STB or Set Top Box) will be repaired or reused. Telkom partners with certified hazardous and electronic waste processors, one of which is PT Triguna Abadi, to support the implementation of the Eduvice program (see Highlight Box). Telkom conducts partner selection to ensure that waste management procedures by partners run in accordance with Local Regulations. In the future, Telkom is committed to ensuring the implementation of responsible waste management practices.
