Sustainability Report 2023 02 board statement efficient machinery in our processes to further improve our environmental performance. We commenced our Task Force on Climate-related Financial Disclosures (TCFD) journey in 2022 and established an internal qualitative climate risk and impact assessment. Through the journey, we identified key climaterelated risks, such as extreme heat, flooding and increases in carbon pricing which may financially impact the business. We are currently working towards the development of more comprehensive climate disclosures, in line with the Accounting and Corporate Regulatory Authority (ACRA) and Singapore Exchange Regulation (SGX Regco) requirements of reporting climate-related disclosures (CRD) from financial year 2025 for listed issuers. We are further building on our effort in preparation towards including the International Sustainability Standards Board (ISSB)-issued IFRS Sustainability Disclosure Standards. SUPPORTING THE HEALTH AND SAFETY, WELL-BEING OF OUR PEOPLE AND VALUE CHAIN We place a high importance on managing the health and safety of our employees due to the nature of our operations. We emphasise strongly to our people to practise precautionary measures through close monitoring of the mine sites and engage them through the implementation of Standard Operating Procedures, regular briefings, and health and safety trainings. We aim to continue to strive for zero fatalities, occupational illnesses, and work-related incidents. In 2023, we had also kept up with continuing to provide support to the communities around us. We had performed assessments on the needs of the local communities near our mine sites and had supported community projects that had made an impact on the livelihood of these local communities. In total, our community investments had amounted to approximately USD 400,000. practices, including corruption, bribery, fraud and other unethical activities within our operations. We monitor and manage legal, ethical and risk issues within our operations, following the guidance set out by our Code of Ethics and Conduct and Supplier Code of Conduct. Our Whistleblowing Policy and grievance mechanism have established a safe environment for affected stakeholders, including employees or external parties, to voice their concerns about any unethical or unlawful business conduct or dealings, without fear of reprisal, discrimination, or adverse consequences. MANAGING OUR ENVIRONMENTAL FOOTPRINT Recognising the potential negative environmental impacts and risks that could arise from our operations, Geo Energy strives to minimise the impacts and risks by maintaining stringent environmental standards and practices in line with global standards. Our practices are aligned with ISO 14001:2015 standards for Environmental Management Systems (EMS) and we have established an Environmental and Social Management System (ESMS) across all our assets, in accordance with international benchmarks such as the Equator Principles III and IFC Performance Standards (PS), as part of our mitigation and remediation efforts over our operations’ impact on the environment. We are also continuing to refine our greenhouse gas (GHG) inventory in line with best practices such as the GHG Protocol by measuring additional Scope 3 categories in relation to the indirect emissions from our fuel and energy consumption and waste generation. With the recent acquisition of the TRA mine and expansion in our Scope 3 calculations, our total emissions have risen by 15% year-on-year to over 166,000 tCO2e. Despite this result, we remain committed in managing the impacts of our carbon emissions and are exploring use cases of renewable energy, alternative fuels, and energy- [GRI 2-22] Dear Shareholders, We are pleased to present Geo Energy’s 2023 Sustainability Report. Amidst the changing demand on our coal products due to international geo-political events and market shifts, as well as the global energy transition trends, maintaining stewardship over corporate governance of our Group and over the impact of our operations on the environment, economy and the people around us remains to be cornerstones in building a sustainable business. Therefore, we have maintained consistent effort and strategies in ensuring that the environmental, social and governance aspects of our operations and related impacts are being looked after. Our sustainability strategy and management, including identifying, reviewing, and approving the materiality assessment and sustainability reporting, continues to be overseen by the Board and the Chief Executive Officer. The Group's sustainability strategy management team reviews the material environmental, social and governance (ESG) factors to ensure that they remain relevant and aligned with our business direction and growth and continues to be reflective of our stakeholders’ expectations. ENSURING STRONG GOVERNANCE AND RESPONSIBLE BUSINESS ETHICS AND INTEGRITY We believe in upholding strong corporate governance, ethics, and integrity, and conducting our operations in a responsible manner. We continuously evaluate our internal policies and business practices to ensure compliance with laws and regulations, while managing the environmental, social and economic impacts of our operations. We maintain strict compliance with our policies and have zero tolerance for policy breaches and unethical

We will strive towards our strategic objectives and build sustainable business Geo Energy 03 On data security and technology front, we remain cognisant of the associated negative impacts of data security breaches and technological issues on our operations and value chain. We have put in place various preventive and detective measures to reduce and promptly address the risks of digital system disruptions that may impact our operations. In 2023, we did not have any cyber-attack incident, and we will continue to maintain the robustness of our measures to keep our track record. MOVING FORWARD We strive to continue to incorporate environmental, social and governance considerations across our operations to foster sustainable development. The coal produced by the Group, including from the recently acquired PT Triaryani coal mine in South Sumatra, has low ash and low sulphur characteristics. This is in line with the Group's sustainability strategy of achieving a balance between providing a more affordable source of energy with lesser impact to the environment. Furthermore, these coal characteristics allow the Group to command a premium in sales price, enabling the Group to capture the favourable demand outlook. The Group's sustainability strategy and management continues to be overseen by the Board to ensure that environmental, social and governance measures implemented remain relevant and aligned with our business direction and growth, and continues to be reflective of our stakeholders’ expectations. Yours sincerely, Dato’ Charles Antonny Melati Executive Chairman and CEO

Overall, these internationally recognised sustainability reporting standards and frameworks were utilised as they offer comprehensive sustainability disclosure. The GRI Standards are widely recognised as a foundational framework for sustainability reporting while TCFD recommendations act as guidelines in disclosing climate-related financial information useful to investors, lenders, and insurance underwriters. We target to follow industry best practices in monitoring our sustainability performance by transparently and clearly reporting against these reporting practices. ASSURANCE [GRI 2-5] We engaged a third-party consultant to conduct a periodic evaluation of Geo Energy's policies, internal controls, and risk management concerning our sustainability reporting process. Although we have not requested external assurance during this reporting cycle, we will conduct external assurance in the upcoming years. FEEDBACK [GRI 2-3] We appreciate any questions, comments or suggestions to help us improve and progress further on our sustainability reporting journey. Please contact us at investor_ relations@geocoal.com. trading high-quality coal with low sulphur and low ash content from its Triaryani (TRA) coal mining asset located in South Sumatra. The data of GEE and TRA was included in this report from the date of acquisition. The procurement of the TRA mine signifies a significant expansion in our operational scope, which inherently results in elevated emissions in comparison to 2022. The increase in emissions observed can be attributed directly to our operational growth and does not necessarily indicate that our mines’ environmental performance is declining. Acknowledging our biodiversity and environmental obligations, we will endeavour to manage the environmental impact of our operational practice. REPORTING FRAMEWORK This sustainability report has been prepared with reference to the Global Reporting Initiative (GRI) Standards 2021 and GRI 12: Coal sector standards. Further details can be found in the GRI content index on pages 57-66. Given that Geo Energy is a listed entity on the Mainboard of Singapore Stock Exchange (SGX), we comply with the SGX Listing Rule 711 (A) and (B), as well as SGX’s enhanced disclosures on climaterelated information. We have enhanced our understanding of climate risks and opportunities by adopting the Task Force on Climate related Financial Disclosure (TCFD) since 2021, by Geo Energy Resources Limited, and from our mining contractors, PT Bukit Makmur Mandiri Utama (BUMA), PT Lancarjaya Mandiri Abadi (LMA), and PT Putera Kontrindo Abadi (PKA), are included in this report. Singapore and Indonesia are the countries of operation captured within this report.

Geo Energy 11 approach to sustainability [GRI 2-9 to 2-15, 2-1, 2-17 to 2-21, 2-24, 3-1 to 3-3] At Geo Energy, we acknowledge the importance of managing the emissions of our operations while staying committed to running our business with corporate social responsibility concepts to protect our people, environment, and the local communities in which we operate. SUSTAINABILITY FRAMEWORK [GRI 3-1, 3-2] Materiality assessment In 2022, we undertook a benchmarking exercise against our industry peers and stakeholder engagement exercise with our internal stakeholders to understand both positive and negative impacts of our business operations. This process enabled us to identify and validate our materiality topics, and therefore allowing us to assess and prioritise our material topics based on the significance of impacts Geo Energy’s business operations bring to the people, environment, and economy. Our shortlisted material topics are then reviewed and approved by the Board. Geo Energy’s materiality assessment is disclosed with reference to GRI 2021 standards and in line with SGX 27 Core ESG metrics. This year, we reviewed our existing material topics and performed a refresh of material topics, structuring into three key pillars under our sustainability framework. Our key pillars help us to further enhance and prioritise our sustainability strategies and initiatives on the impacts of Geo Energy’s business operations on the people, environment, and economy around us. Whilst our material topics have not changed since our material assessment conducted in 2022, from our review, we have come up with a refreshed list of prioritised material topics as shown below. Our sustainability initiatives and performance are strongly aligned with the three pillars of our sustainability framework above. We will continue to drive performance under each pillar and monitor using key performance indicators and targets which will be further detailed in this report. Managing our environmental footprint • Biodiversity • Energy and climate change • Water and effluents • Waste management Ensuring strong governance and responsible business ethics and integrity • Corporate governance • Risk assessment and management Supporting the health and safety, well-being of our people and value chain • Digitalisation and technology • Supply chain management • Health and safety • Community and well-being • Human capital management • Customer relationship management

Sustainability Report 2023 12 SUSTAINABILITY GOVERNANCE [GRI 2-9, 2-10, 2-11, 2-14, 2-15, 2-17, 2-18, 2-19, 2-20, 2-21, 2-24] We stay committed in maintaining good corporate governance practices through disciplined risk management and strong compliance to policies and regulations. Our sustainability framework is embedded within our management, governed by the Enterprise Risk Management (ERM) Working Group, where the ERM Working Group identifies sustainability risks and opportunities across operations. This enables the Group to create and deliver tailored solutions, as well as to generate value. The Board (including the Board of Directors) represents the highest governance body in Geo Energy and recognises the importance of managing the Group’s impacts on the people, environment, and economy around us. The Board is assisted by the Chief Executive Officer (CEO), who oversees the management of the Group’s sustainability strategies, key ESG related matters including climate-related issues and their related impacts, the review of the materiality assessment and the relative importance of the material topics to ensure that they remain relevant to our business context, as well as the management of stakeholders’ expectations. Where there have been any major changes and any areas of concern to be considered during the materiality assessment, the refreshed list of material topics will be reviewed and approved. Our CEO, together with respective Heads of Departments and the Mining Operation Team, are responsible for managing sustainability related matters across day-to-day operations and areas of concern. The Board is responsible for overseeing the corporate governance of the Group. The principal functions of the Board are: • overseeing the Group’s long-term strategic objectives and direction, taking into consideration sustainability issues; • overseeing the management of the Group’s business affairs, financial controls, performance and resource allocation; • assisting the establishment of prudent and effective controls to assess and manage risks, safeguard shareholders’ interests and the Group’s assets; and • setting Geo Energy’s values and standards (including ethical standards) and ensuring that obligations to shareholders and other stakeholders are understood and met. The Board (includes Board of Directors) Respective Heads of Department and Mining Operation Team Enterprise Risk Management (ERM) Working Group CEO

Geo Energy 13 The Board comprises of three committees who are in charge of the execution of its responsibilities and decision-making. The Committees and their respective responsibilities include the following: • Audit and Risk Committee (ARC): Holds responsibility in reviewing the top risks, including climate-related risks identified by the ERM Working Group. The ARC also reviews and approves the adequacy and effectiveness of Geo Energy’s risk management and internal controls on key risks, including climate risks. • Nominating Committee (NC): Works together with the Board in the process for the selection, appointment and reappointment of directors. The NC reviews and selects candidates with relevant expertise, experience, and who display an awareness on the key climate issues impacting the coal industry and Geo Energy’s operations. • Remuneration Committee (RC): Reviews and recommends the Board and key management personnel’s remuneration framework to ensure that rewards are linked to corporate and individual performance. The Board is represented by six1 directors2, four of whom are independent directors. The composition of the Board is listed below: • Mr Charles Antonny Melati (Executive Chairman and CEO) • Mr Dhamma Surya (Executive Director) • Mr Lu King Seng3 (Lead Independent Director) • Mr Ali Hery (Independent Director), appointed on 1 June 2023 • Mr David Yan Kin Pung (Independent Director), appointed on 15 November 2023 • Mr Lee Chee Tak (Independent Director), appointed on 15 November 2023 ERM Working Group The ERM Working Group, consisting of the CEO, CFO and various heads of department, identifies sustainability and climate-related risks and opportunities across operations, enabling the Group to create and deliver tailored solutions to meet its objectives. An annual risk workshop was conducted by the Company’s ERM consultant, PricewaterhouseCoopers Risk Services (PwC) to facilitate management’s identification of strategic, financial, operational, information technology and regulatory/compliance risks that are likely to pose a barrier to the achievement of the Company’s strategic business objectives. The results of the risk workshop provided management with a more systematic approach to understand the major risks and that sufficient rigour has been applied to manage and mitigate these risks, including climate risks. The Risk Owners are responsible to monitor and manage these risks. The top risks and the full list of risks identified will be presented to the Audit and Risk Committee (ARC) and Board for review and approval. Nomination process for Board of Directors [GRI 2-10] Our Nominating Committee (NC) works closely with the Board during the process for the selection, appointment and reappointment of Directors. Executive recruitment services, recommendations and contacts are utilised to identify qualified and experienced candidates. The NC reviews the résumé of candidates, considers their skills, knowledge and experience, interviews shortlisted candidates, and recommends the most suitable individuals to the Board for approval. Given also the importance we place on sustainability, candidates must also display an awareness of key ESG issues impacting the coal industry and Geo Energy’s operations. Board appointments are made through a Board resolution. The composition of the Board is reviewed on an annual basis by the NC to ensure that the Board has the appropriate mix of expertise, experience, balance, diversity and knowledge of the Group and collectively possesses the necessary core competencies for effective functioning and informed decision-making. The Board as a group comprises members with core competencies in accounting and finance, business and management experience, industry knowledge, strategic planning and customerbased experience and knowledge. 1 This excludes our former independent directors Mr Soh Chun Bin (retired on 28 April 2023), Mr Ong Beng Chye (retired on 14 November 2023) and Mr Jim Rogers (retired on 14 November 2023). 2 In 2023, 67% (4 out of 6) of our directors are independent, where 100% are male and 0% are female. 3 Mr Lu King Seng is retiring as Directors on 26 April 2024.

Sustainability Report 2023 14 The Board is evaluated annually to ensure that they continue to be relevant and well-equipped to oversee the Group’s sustainability strategy and development. The Board, particularly first-time directors, will undergo training in the roles and responsibilities of a director of an entity listed on the SGX-ST as prescribed by the SGX-ST within one year from the date of his or her appointment to the Board. Such training includes ESG Essentials. The Board is also encouraged to undergo continuous professional development by attending relevant seminars or training related to the Group’s business operations and sustainability strategy and development, as recommended and funded by the Company. For the re-appointment of Directors, pursuant to the Constitution of Geo Energy, each Director is required to retire at least once every three years. Newly appointed Directors are required to retire at the next annual general meeting of the Company following their appointments. The retiring Directors are eligible to offer themselves for re-election. Shareholders play a role in determining whether the Director can be re-elected following their retirement from the Board. Shareholders’ opinions on this matter are solicited at the annual general meetings. The independence of an appropriate candidate from the Board is determined at the recruitment stage. The NC conducts a detailed background check on each candidate to identify any potential conflicts of interest with Geo Energy. The independence of each Director is also reviewed annually by the NC. The Directors of the Board are required to disclose to the Board their relationships with the Company, its related corporations, its substantial shareholders, or its officers, which may affect their independence. For independent Directors, their tenure for serving on the Board is limited to 9 years. Each independent Director is required to complete a checklist annually to confirm his independence. CONFLICT OF INTEREST [GRI 2-11, 2-15] Geo Energy’s personnel, including the Board, are required to disclose any direct or indirect interest in any of the Company’s suppliers, customers or competitors which could conflict with the Company’s best interests. For Directors deemed to be independent, their independence is reviewed annually by the Nominating Committee. Each independent Director is required to complete a checklist annually to confirm his/her independence based on the guidelines as set out in the Code. The Board has delegated the Audit and Risk Committee (ARC) to review any potential conflicts of interest that may arise, according to Geo Energy’s Conflict of Interest policy. Any Director who faces a conflict of interest or a possible conflict of interest, in relation to a matter, must promptly declare his interest

Geo Energy 15 with details of the conflict and to recuse himself/ herself from discussions and decisions on the matter. Any potential conflict of interests will be disclosed in Geo Energy’s annual report. EVALUATION OF THE PERFORMANCE OF HIGHEST GOVERNANCE BODY [GRI 2-18] A formal assessment process is in place to assess the effectiveness of the Board, the Board Committees, and each Director annually. Each director completes a self-assessment and self-evaluation form which contains objective performance criteria and factors such as the composition and effectiveness of the Board and the Board Committees, quality of information and decision making, Boardroom activities, Board’s relationship with the Management, performance, calibre and personality, as well as a Director’s skills, knowledge, experience and contributions (including the management of the organisation’s impacts on the economy, environment and people). Assessment results are analysed with key areas for improvement and followup actions are highlighted and discussed at the Board meeting. REMUNERATION POLICIES [GRI 2-19, 2-20] The Remuneration Committee considers all aspects of remuneration, including but not limited to director fees, salaries, allowances, bonuses, options, sharebased incentives and awards, benefits-in-kind and termination terms to ensure that they are fair. Geo Energy has a structured process in determining remuneration package, which considers remuneration competitiveness in the industry, the Group’s performance, and individual performance of the Directors and key management personnel. For more details on level and mix of remuneration, please refer to our Annual Report 2023 on page 27. ANNUAL TOTAL COMPENSATION RATIO [GRI 2-21] Geo Energy's annual total compensation ratio stands at 498.6 (2022: 255.94). This figure is high due to a larger proportion of employees from the mine site who receive lower annual remuneration. The percentage decrease in the annual total compensation ratio is 11.4 as the median total compensation showed a decrease, mainly attributed to fluctuations in exchange rates between the Indonesian Rupiah (IDR) and the US Dollar (USD). STAKEHOLDER ENGAGEMENT [GRI 2-29, 3-3] Geo Energy recognises the importance of stakeholder engagement in the sustainable development and strategic management of our business. It enables us to manage our stakeholder expectations, manage risks and opportunities associated with sustainability issues, as well as build trust and support during our sustainable journey. We engage with our stakeholders regularly via formal and informal channels. Our Stakeholder Engagement Plan (SEP) was established to facilitate Geo Energy’s sustainability planning and strategic development, including relevant engagement activities to gain insights and identify key issues with our key stakeholders. Our stakeholder engagement process encompasses one-way and two-way communication methods, such as websites, presentations, and interviews.

For evaluation of an existing vendor, the Group will perform a yearly review and assessment on the competitive pricing, after sales service, satisfactory service, internal financial and trade sanctions, response time to queries and delivery schedule to determine whether such vendor will be continued as an approved vendor or to cease the transaction with such vendor. The above two sets of criteria apply to the bidding process.
