Sustainability Report 2022 PT Telkom Indonesia (Persero) Tbk 17 MESSAGE OF THE PRESIDENT DIRECTOR 02 18 Message of the President Director

PT Telkom Indonesia (Persero) Tbk 18 Sustainability Report 2022 Chapter 02 MESSAGE OF THE PRESIDENT DIRECTOR MESSAGE OF THE PRESIDENT DIRECTOR [2-14] Telkom implements sustainability practice policies in line with its digital transformation activities to support the society’s economic growth, including the digital economy. ” “ Esteemed Stakeholder, TelkomGroup continuously supports the realization of Sustainable Development Goals (SDGs), and we recognize the importance of managing an ethical business as we create a better future. With regards to improving our sustainability performance, our support is implemented through our consideration for planet, people, partnership, prosperity, & peace (5P) within all our business activities. We also continue to manage environmental, social, and governance (ESG) risks, in particularly the minimization of negative impacts as we increase value as a positive impact. Moreover, the management of the ESG aspects is accompanied by efforts to improve various telecommunication technology innovations that have become part of the current day-to-day life. We manage ESG aspects in accordance with our scope of business as a digital telco company. To support of these activities, we have also done an ESG risk mapping and mitigation and developed sustainability pillars. POLICIES TO RESPOND TO CHALLENGES Telkom implements sustainability practice policies that are in line with its digital transformation activities supporting society’s economic growth, including the digital economy. The increasing need for digital technology through telecommunication innovations has to be balanced through the management of social and environmental impacts. We are therefore committed to implementing a sustainability strategy based on three main pillars: the Right Environmental Approach; the Right People; and the Right Governance. With regard to the Right Environmental Approach pillar, we conduct business in an environmentally responsible manner by working to reduce the negative environmental impact of our operations. The Right People pillar is our commitment to create a positive impact for all, including employees, customers, communities and other stakeholders. Meanwhile, the Right Governance pillar demonstrates our commitment to apply sustainability governance, legal and regulatory compliance, and ethical business practices; to respect customer privacy and human rights; and to manage risk management systems related to data security systems and economic aspects. The three Pillars are intended to encourage a more balanced ESG performance. SUSTAINABILITY PERFORMANCE ACHIEVEMENTS Throughout 2022, TelkomGroup carried out initiatives that support sustainability practices and that manage the challenges of a digital telco company. Relating to environmental aspects, Telkom undertook initiatives to reduce energy use and reduce greenhouse gases (GHG) emissions. We have identified that the management of data centers is the biggest energy consumer in the Company’s operations. At Telkomsigma, our Subsidiary, we have reduced energy consumption of data centers by adjusting the temperature and humidity of the cooling devices. In 2022, Telkom expanded Telkomsigma’s data center segment to PT Telkom Data Ekosistem (NeutraDC) with the aim of developing a data center ecosystem. The development of the data centers is balanced with decarbonization initiatives through the Green Data Center program. As such, we use energy-efficient, cutting-edge technologies in our operational activities to reduce GHG emissions. Additionally, our Base Transceiver Stations (BTS) utilize solar cells and fuel cells, both clean and environmentally-friendly energy sources.

PT Telkom Indonesia (Persero) Tbk Sustainability Report 2022 19 Ririek Adriansyah President Director Throughout 2022, TelkomGroup carried out initiatives that support sustainability practices and that manage the challenges of a digital telco company.

PT Telkom Indonesia (Persero) Tbk 20 Sustainability Report 2022 Chapter 02 MESSAGE OF THE PRESIDENT DIRECTOR We have been consistent in managing our e-waste and collaborate with other parties so that these can be reused. We have reduced solid waste by using SIM card raw materials, and we have replaced physical vouchers with electronic ones. Moreover, we have continued with our waste management campaign, both internally and externally through the Electronic Device Donation for Education (Eduvice) assistance program. Telkom invites its employees to manage their e-waste by disposing their old devices in the electronics boxes that we’ve made available. We work with partners to recycle electronic waste into value-added items to be utilized and distributed to the community. Relating to social aspects, we continued to develop training and education programs to create human resources that can adapt to digital technology. Additionally, we also enforced fair and ethical employment by upholding human rights, gender equality, diversity, and inclusiveness. By the end of 2022, the composition of female employees reached 34% of total employees. There were 596 new hires, of which 52.2% were female new hires. Meanwhile, we recorded an employee engagement index of 89.79%, illustrating the level of comfort that most of our employees have in working for the Company. Through the HR competency development program, we recorded 53.27 hours of training per employee per year. The social aspects that we manage also include the implementation of Occupational Safety and Health Management System (SMK3). The implementation of SMK3 not only encompasses employees, but vendors and stakeholders in our work areas. To increase awareness regarding the importance of OHS to employees and work partners within TelkomGroup, we promote OHS aspects at various instances. To prevent accidents, some of the mandatory implementations range from Safe Work Readiness Check List and Safety Talk to direct field supervision through HSE Patrol and Management Visits. Additionally, we also ensure that our vendors comply with our safety standards and certifications. What is more, the management of social aspects related to consumers includes managing data security and privacy, as well as consumer experience and satisfaction. TelkomGroup pays close attention to the handling of technological disruptions that reduce service quality and convenience so that we can provide the best experience to our customers. Telkom always prioritizes consumer convenience by ensuring data security systems and customer privacy. Data security protection is carried out throughout the information lifecycle: from personnel, processes, applications and services, database systems, operating systems, networks to hardware. Telkom supports the Government’s policy to purchase products and use domestic services by prioritizing local supplies to satisfy the procurement of goods and services. This policy is one of our contributions in support of Indonesia’s economic growth. Within TelkomGroup’s supply chain, we have conducted GSE-related assessments of partners/suppliers. In 2022, 99% of our partners/suppliers are local, and TelkomGroup’s Domestic Content Level (TKDN) achievement is around 37.02% of CAPEX expenditure and 75.02% of OPEX expenditure. As part of the community, TelkomGroup oversees community development programs that are aligned with SDG support. TelkomGroup is a significant contributor to the connectivity and expansion of digital-based telecommunication infrastructures to nearly all regions of Indonesia, including Frontier, Outermost and Least-Developed (3T) areas. In line with the development of the digital economy, we have synergized with stakeholders to develop several strategic programs. To support the growth of the digital ecosystem in Indonesia, Telkom has launched Leap, an umbrella brand for digital products developed by TelkomGroup. We anticipate that digital products and innovations under Leap will help many sectors and industries while enabling collaborations with various agencies to increase digital inclusion.

PT Telkom Indonesia (Persero) Tbk Sustainability Report 2022 21 TARGET ACHIEVEMENT STRATEGY To ensure the achievement of our performance targets, the Company carries out strategies that strengthen sustainable governance. We have developed a monitoring and evaluation process for the management of the ESG aspects into our business strategies. This includes the application of sustainability governance with the integration of GCG implementations and business ethics. In carrying out our strategies in support of our sustainability performance, we pay close attention to challenges and opportunities, so as to develop future strategies that are more pertinent. We realize that digital telecommunication offers great opportunities and business prospects that can drive the advancement of the digital economy. In addition to providing convenience and connectivity, digital telecommunications can be used to expand the value chain of a business. Consequently, TelkomGroup will need to prepare a more comprehensive ESG-based risk management system with a view to minimize risks and create new opportunities.

It is hoped that this collaboration will be able to create 200,000 SOE digital talents up to 2024. WORK TIME AND LEAVE RIGHTS [401-3] We clearly regulate work, rest and leave arrangements as stated in CBA and Company regulation. The employee’s working hours policy does not exceed the maximum amount regulated by law. Therefore, we ensure that there is no forced labor practice within the TelkomGroup. Since COVID-19 pandemic, TelkomGroup has implemented flexible work time setting (FWA) which is divided into Work from Home (WFH), Work from Office (WFO), and Hybrid (WFO-WFH). In telecommunications industry, the work settings are very suitable to be applied in our environment. The calculation of working hours from the application of FWA is a maximum of eight hours per day. To monitor and ensure that employees remain productive even outside the office, Telkom has developed an information system “HC Super Apps” related to monitoring the work performance of both WFO and WFH employees. The application is also used for attendance and recording of daily activities that can be monitored by the direct supervisor. Meanwhile, employee leave rights are regulated in PKB with the provisions of each employee entitled to 12 days of annual leave. Beside annual leave, Telkom also provides other leave rights such as: 1. Hajj leave for 45 days. 2.

The policy was developed with a 3P + 1L principled strategy namely; Pay for Person (according to the required competencies), Pay for Position (according to the level of responsibility and accountability), Pay for Performance (according to performance in achieving targets), and Pay for Location (according to the city of work location). This principle proves the Company’s commitment to maintaining internal equality which does not differentiate remuneration for male and female employees, both at the lowest level up to the senior management level. The remuneration policy is prepared by referring to the applicable regulation and their amendment. Telkom and its Subsidiaries comply with the provision of Provincial Minimum Wage (UMP) regulation by setting the lowest employee salary above UMP.

PT Telkom Indonesia (Persero) Tbk Sustainability Report 2022 57 EMPLOYEE PERFORMANCE MEASUREMENT [404-3] Employee performance measurement is carried out using two methodologies, namely Performance Appraisal measurement and Competency & Behavior Appraisal measurement. Since 2022, there has been a full implementation of system changes for measuring employee performance, namely using KPI-OKR hybrid system and Competency & Behavior Appraisal (CBA) system. Performance Appraisal is carried out in a KPI-OKR hybrid manner by using a combination of Joint KPI based on Unit Performance Scores as a representation of shared/ collective performance and OKR Score based on values from OKR Committed as a representation of individual/ specific performance. Meanwhile, Competency & Behavior Appraisal (CBA) is carried out using a multi-rater and supervisor’s assessment. The result of Performance Appraisal is the P (Performance) value and CBA produces a K value (Competence) and a B value (Behavior). Employee performance goes through a review process that is carried out every year. Starting in 2022, employee performance is measured based on the success of completing activities to support the achievement of integrated targets both as units and sub units. This mechanism is carried out through the development of an Objective Key Result (OKR) based performance appraisal system. In addition to assessing the ability of employees to complete tasks, Telkom also conducts Competency & Behavioral Analysis assessment using a multirater or 360 degree scheme. In 2022, all employees (100%) have received performance appraisals.

PT Telkom Indonesia (Persero) Tbk Sustainability Report 2022 Chapter 04 SUSTAINABILITY PERFORMANCE 66 SYSTEMIC RISK MANAGEMENT [201-2] [TC-TL-550A.1, TC-TL-550A.2] To minimize systemic risk, TelkomGroup continues to monitor technological and district disruption. The disruption that we face is one of them is caused by natural condition, such as damage in sea cable infrastructure due to volcanic eruption and earthquake in the sea. We also monitor disruption in fiber optic backbone system originating from sailing activity, road excavation work and vandalism, such as copper cable theft, ODC, BTS, and others. Other causes of disruption come from migration of new infrastructure/system, process of integration between different system does not run well, as well as the management of asset protection system that are less effective. Throughout 2022, we faced 3,927 disruptions to fiber optic network and 19 disruptions of wet plant on submarine cable communication system (SKKL). The following table presents data on fiber optic backbone and SKKL disruption for the past three years.

Sustainability Report 2022 PT Telkom Indonesia (Persero) Tbk 67 INCLUSIVE TELECOMMUNICATIONS ACCESS [203-1] In order to realize inclusive telecommunication, Telkom continues to focus on building infrastructure in all regions, especially 3T area to be able to provide inclusive digital solution for all levels of society. With the spirit of transformation, Telkom is also committed to not only presenting various digital services, but also increasing digital literacy among public so that they can create a comprehensive digital ecosystem. The use of digital technology is believed to accelerate economic recovery. Telkom’s real step in building digital connectivity to remote corners of the archipelago, is realized by having a fiber optic network infrastructure reaching 171,654 km or the equivalent of 4 times circumference of the earth. This connectivity is supported by 2 satellites with a total capacity of 109 transponders that can reach remote villages. With comprehensive network connectivity, people in the regions have the same opportunities in running a business and getting qualified facilities to support their lives. In addition, Telkom also supports the realization of digital inclusion continuously by building telecommunication infrastructure, both in remote areas of Indonesia and internationally. Through Telin, we joined Southeast Asia-Middle East-Western Europe 6 (SEA-ME-WE 6) international maritime cable communications system consortium. The SEA-ME-WE 6 consortium consists of various major operators from various countries in the world, including Bangladesh Submarine Cable Company, Bharti Airtel Ltd. (India), Dhiraagu (Maldives), Djibouti Telecom, Mobily (Saudi Arabia), Orange (France), Singtel (Singapore), Sri Lanka Telecom, Telecom Egypt, Telekom Malaysia, Telin (Indonesia), and Trans World Associates (Pakistan). INTERNET POSITIVE AND PARENTAL CONTROL PROGRAM Currently, people use the internet more for communication, such as electronic mail (e-mail) and social networking because it is more effective and efficient. However, the ease of internal access and increased digital media still have risks that need to be managed, such as digital addiction, non-educational, and unhealthy content. The influence of negative content can interfere with the mental health of its users. Telkom cares about the impact of internet usage for consumers. Therefore, we continue to campaign for a healthier internet presence. One of TelkomGroup’s efforts to promote a healthier internet is by blocking content on the internet related to gambling, pornography, racism, fraud, copyright infringement, normalization of violence, and content that does not reflect the noble moral values of the Indonesian nation. Apart from that, we also provide parental control features on IndiHomeTV to limit viewing or content for families.

PT Telkom Indonesia (Persero) Tbk Sustainability Report 2022 Chapter 04 SUSTAINABILITY PERFORMANCE 70 In implementing data governance system, Telkom implements several data security mechanisms, including: 1. Obligation of approval from the Director of relevant unit that carries out business activities that require data transactions. 2. Data control by appointing a Data Owner for each unit. 3. Cryptography, so that only certain PIC have the right to access data and it is confidential. 4. Masking to disguise all personal data. In addition, we have carried out awareness-raising programs, as well as conducted an internal audit process for data management system in both Subsidiaries and Telkom. Audit for Specific Data Processing (PDP) will only be implemented in mid 2022. CUSTOMER DATA MANAGEMENT FOR SECONDARY PURPOSES [TC-TL-220A.2, TC-TL-220A.4] Practice of managing personal data for secondary purposes usually occurs when the data is to be displayed to third parties. In this practice, customer are given option by electronic system operator to give approval whether or not personal data can be used and/or displayed to third parties. An example of using data for secondary purposes is when law enforcement official have the right to submit request for using customer data to resolve a case, especially fraud case. Management of this practice at Telkom refers to Regulation of the Director of Compliance & Risk Management No. 603.01/r.00/HK000/COP-D0020000/2011 dated July 6, 2011 regarding Implementation Guidelines for Providing Records and Data Usage of Telecommunication Facilities to Law Enforcement Official. Throughout 2022, law enforcement officials was submit 25 requests related to tracking of IP address usage, call data record, and customer data. Telkom provides assistance in providing data with the aim of helping resolve case and all request have been fulfilled. IMPROVING CYBER SECURITY [TC-TL-230A.2] Along with the increasing development of technology, the types and cyber threats are also increasingly diverse. Therefore, we need to strengthen our security system to mitigate cyber threat. As part of preventive measure, TelkomGroup has identified several causes that may raise information security risks, including: 1. Lack of accuracy and stakeholder concern of information security aspect. 2. There are certain motivation such as cybercriminal who seek financial gain, competitor who damage the opponent’s reputation, and hacker who seek publicity. 3. Weakness in the supply chain (various vendors and technology used allow for security gap that give rise to security threat). 4. Increasing and widespread use of innovative technology, such as cloud, make hacker and cyber adversary challenged to exploit the weakness of the technology and their ecosystem. 5. Security gap in information security system, both physical and non-physical. We recognize that cyber threat and attack can impact a Company’s revenue and reputation. Therefore, TelkomGroup continues to mitigate and manage cyber threat/attack on network, application, and data so as not to cause significant negative impact. Some of the controls that we have implemented to mitigate these threat include: 1. Increase stakeholder awareness of the company’s information security aspect. 2. Improve preventive action in the form of periodic vulnerability assessment and penetration test. 3. Perform daily security check on IT infrastructure. 4. Prepare recommendation based on information security management. 5. Carry out intensive coordination with parties related to handling cyber security (such as National Cyber Crypto Agency). Telkom’s efforts to improve cyber security are by developing a Cyber Security Operation Center which has a function as a center for monitoring, detecting, and executing responses to information security incident. The main activities of Cyber Security Operation Center are security monitoring, incident response management, vulnerability assessment, penetration testing, log management & analysis, and security awareness. This center operates 24x7 to help Telkom anticipate and respond more quickly and effectively in providing information related to cyber security. In addition, TelkomGroup’s efforts to deal with cyber security threats are by increasing awareness and procedures for maintaining data privacy. The awareness activities that we carry out include awareness campaigns on cyber security through the Company’s mass communication media. One of them is via e-mail, messages via WhatsApp, Telkom’s internal portal, as well as TelkomGroup’s internal collaboration application Diarium.

The management policy is implemented in reference to the Resolution of Director of Finance Number PR 301.08/r.05/HK240/COP-K0700000/2022 dated May 25, 2022 regarding Guidelines for Procurement Implementation. Each partner is required to sign an integrity pact containing a statement not to engage in corrupt practices, price collusion, conflict of interest, fraud, and anti-bribery in every procurement process that carried out. TELKOMGROUP SUPPLY CHAIN New Supplier 1. Infrastructure Facilities 2. Transport 3. Access 4. Switching & Routing 5. Information Technology New Supplier 6. Professional Services 7. Lease 8.

Online registration stage through Supply Management and Logistic Enhancement (SMILE) application. 2. Selection stage includes an assessment according to business classification and other criteria to produce a short-list. 3. Determining eligible bidder stage, namely potential partner who are entitled to be involved in the procurement process. Prospective partner are directed to register through SMILE application, then all potential partner will be checked for the completeness of company document in general. Furthermore, committee will conduct a selection that includes an assessment aspect of Quality, Cost, Delivery and Service (QCDS). This policy is in accordance with Company Regulation No.PR.301.03/r.00/HK.240/COP-D0050000/2012 dated June 29, 2012 regarding Supplier Management. Supplier evaluation includes aspect of Quality, Cost, Delivery and Service (QCDS). In addition, TelkomGroup also assesses ESG aspect of potential partner. We pay attention to the policies and compliance of prospective partner with respect to fulfilling integrity and socio-environmental aspects such as implementing a code of ethics, respecting human rights, implementing OSH, and managing the environment.

Sustainability Report 2022 PT Telkom Indonesia (Persero) Tbk 75 The result of selection will produce a short-list up to the determination of the winner/executor of the procurement. The next stage is an assessment of the partner’s performance in carrying out the procurement of related good and/or service up to the handover/ acceptance of work. When already working together, Telkom conducts supplier performance assessment to ensure that there is a good, sustainable cooperative relationship, and of course provides optimal benefit for both parties. Assessment includes mandatory and option aspects. This performance assessment is a form of our mitigation effort against existing risk and to ensure there is no fraud in the supply chain. The result of assessment will determine the risk level of the partner. If there is a high risk, monitoring and re-evaluation will be carried out on the partner concerned. In 2022, there were no blacklist action against partners who have poor performance based on evaluation results. We also noted that none of the partners had their employment terminated because they were deemed unable to carry out the work. On the other hand, from the implementation of the assessment of ESG aspects in TelkomGroup supply chain, we note that there were no partners who are currently involved in legal sanctions related to socio-environmental non-compliance. LOCAL PARTY ENGAGEMENT [204-1] Engagement of local party including local supplier can contribute to supporting economic growth in Indonesia. Telkom seeks to prioritize local supplier to meet the procurement of good and service, and use domestically produced component. Local partner/supplier, namely supplier who are domiciled in Indonesia, can support TelkomGroup operation in various regions of the archipelago and help reduce environmental impact, namely a lower carbon footprint when compared to supplier from abroad. Telkom is involved in cooperation with 99% or 893 local (Indonesian) partners out of 898 total partners, as well as 1% foreign partners as of the end of 2022. The engagement of local parties has increased by 1.02% when compared to last year, namely from 884 in 2021 become 893 work partners in 2022. DOMESTIC COMPONENT LEVEL (TKDN) As a SOE, Telkom supports TKDN to increase. However, the use of domestic product in every procurement process carried out by TelkomGroup still considers quality aspect and economic financial aspect of good and/or service procured. Throughout 2022, TelkomGroup’s TKDN achievements are recorded at around 37.02% of CAPEX expenses and 75.02% of OPEX expenses.
