INTEGRATED ANNUAL REPORT 2025

Our Value Creatıon

Our integrated business model combines a multi-technology power generation portfolio, energy trading and digital energy capabilities. Together, these capabilities enable us to create value not only through electricity generation, but also by improving system flexibility, optimizing market opportunities and supporting Türkiye’s energy transition. They operate across an integrated value chain spanning upstream inputs and strategic dependencies, operational activities, and downstream markets and stakeholders, creating financial, system, social and environmental value.

Our value chain includes the key resources, partnerships and relationships that support our business, from securing energy resources, technology, financing and grid access to generating electricity, managing commercial activities and delivering digital energy solutions. It also provides the framework through which we assess the current and potential impacts of sustainability-related risks and opportunities on our business model and identify where these impacts are most significant.

HOW VALUE FLOWS THROUGH OUR BUSINESS

Our upstream activities depend on reliable access to energy resources, fuel, grid infrastructure, technology, financing and strategic partnerships. Together, these inputs support operational continuity and future growth. Our portfolio depends on natural gas, domestic lignite resources at the Tufanbeyli Energy Base, and the availability of water, wind and solar resources. These factors influence both operational performance and exposure to climate-related risks. Technology providers, EPC contractors and long-term service partners play an important role in project delivery and asset performance. Grid connection capacity and supplier management also support reliable system integration.

Our operations are centered on the integrated management of a multi-technology generation portfolio, trading and commercial optimization activities, digital and data-driven capabilities, and innovation initiatives supporting the energy transition. Key sustainability-related risks and opportunities relate to asset performance, generation reliability and renewable capacity growth. They also include emissions intensity, energy price volatility, physical climate risks, regulatory developments and digital resilience. Operational performance depends on a skilled and engaged workforce. We strengthen asset reliability through health and safety, technical capability development and effective contractor management across our generation, trading and digital operations. Our operations are guided by our Net Zero 2040 commitment. The Climate Transition Plan outlines how we will reduce emissions intensity, expand renewable capacity and transform our thermal assets over time.

Trading and commercial optimization activities are one of the primary mechanisms through which our generation portfolio creates value under changing market conditions. Our trading activities include domestic and international energy markets, price risk management, renewable energy certificates, carbon markets and cross-border trading. Together, these activities support cash flow, profitability and market resilience.

Digital and data-driven transformation supports all stages of our value chain. The Senkron Remote Operations Center connects advanced analytics, AI, digital twin technologies and remote monitoring across our operations. Together with OT/SCADA integration and cybersecurity capabilities, these tools improve operational efficiency, strengthen asset reliability and support better decision-making.

Our downstream activities represent the stage where generated electricity, commercial products and digital energy services reach markets, customers and system stakeholders.

Our downstream activities serve wholesale energy buyers, industrial customers, PPA counterparties and international trading partners. We also provide renewable energy certificates and other solutions that support our customers’ decarbonization goals. System-level outputs include security of supply, balancing and ancillary services, and renewable integration. Together, these channels create financial, system and sustainability value.

HOW WE GOVERN AND MANAGE VALUE CREATION

The activities across our value chain are guided by our governance framework, strategic priorities, risk and opportunity management processes, and standards of business conduct. Together, these mechanisms help ensure that value creation remains aligned with our long-term objectives while supporting operational resilience, financial discipline and responsible growth.

We assess sustainability-related risks and opportunities across our business model, portfolio and operations. Our assessments consider both current and potential impacts over the short, medium and long term, including their effects on investments and financial performance. Assessments are informed by our double materiality analysis and consider potential effects on revenues, operating costs, cash flows, asset values and capital allocation decisions.

Risk and opportunity considerations are integrated into strategy development, portfolio management, investment planning, trading activities, operations, financial planning and sustainability governance processes. This enables us to identify emerging challenges and opportunities across the value chain while strengthening our ability to respond to evolving market, regulatory, technological and environmental conditions.

The governance of our value chain is supported by our commitment to ethical business conduct, regulatory compliance and responsible decision-making. These principles shape stakeholder relationships, support operational integrity and reinforce consistent business practices across the organization. Our approach is further shaped by our six Strategic Priorities: We Ensure System Reliability, We Allocate Capital with Discipline, We Optimize Value

Across Markets, We Run the Business on Data, We Empower Human Potential and We Drive the Energy Transition Responsibly. Together, these priorities connect strategy, investment decisions, risk management and sustainability objectives, providing the foundation for long-term value creation. Each priority is most concentrated at a particular stage of the value chain: System Reliability in operations; Capital Discipline across upstream investment and operations; Value Optimization in trading and downstream markets; Run the Business on Data as a cross-cutting capability; Human Potential across the workforce and supply chain; and Responsible Energy Transition spanning the entire value chain.

Looking ahead, our value chain is expected to evolve significantly toward our 2030 and 2040 milestones. Renewable generation capacity is targeted to increase substantially, supported by the commissioning of the YEKA-2 and YEKA-2024 wind projects, hybrid renewable-plus-storage configurations and the technological transformation of thermal assets. Trading capabilities are set to expand across European markets, digital infrastructure to deepen through AI-driven analytics, and upstream dependencies to shift toward renewable technology supply chains and critical mineral sourcing.

Stakeholder engagement is a core element of our governance and decision-making and long-term value creation approach. Through structured dialogue with stakeholders across our value chain and the broader ecosystem in which we operate, we not only seek to understand expectations, impacts, risks and opportunities, but also translate stakeholder insights into concrete business, investment and sustainability decisions. In this respect, stakeholder engagement serves as an important feedback mechanism that helps us strengthen resilience, improve project design, manage environmental and social risks, and ensure that our activities remain responsive to local needs, regulatory expectations and societal priorities.

Stakeholder engagement supports our ability to maintain strong relationships, strengthen resilience and respond effectively to changing markets, regulatory, environmental and societal conditions. The perspectives gathered through engagement activities contribute to the identification and assessment of sustainability-related matters and provide an important input to our Double Materiality Assessment.

In 2025, stakeholder engagement continued to generate tangible outcomes across our operations and investment planning. Feedback received through site surveys, consultations with local communities, engagement with public authorities, beneficiary feedback and dialogue with other stakeholder groups helped us better understand local sensitivities, expectations and potential impacts. These inputs were reflected in project design reviews, environmental and social management measures, cultural heritage risk management, social contribution planning and selected investment decisions.

Examples of stakeholder engagement outcomes in 2025 included:

  • What we learned:Community consultations and site-level engagements helped us better understand local expectations, land use patterns, community sensitivities and cultural heritage values, including potential tangible and intangible cultural heritage assets in project areas.
  • What we revised:Community-level dialogues contributed to the refinement of project design, including design changes to investment project layouts to prevent and minimize potential impacts on local communities, land use and surrounding assets.
  • What we improved:Feedback from local stakeholders and beneficiaries supported the design of social contribution and local value creation initiatives. The outcomes and long-term impacts of these initiatives will be monitored during the 2026–2030 period.
  • What we decided:Stakeholder engagement, site surveys, technical assessments and official dialogue with relevant authorities informed key project-level decisions, including Enerjisa Üretim’s decision not to proceed with the Arturna-II WPP Project under the YEKA-2 WPP tender in Muğla to avoid potential cultural heritage-related impacts.
  • How we strengthened risk management:The findings gathered through engagement and assessment processes were communicated internally and integrated into construction planning, design reviews and environmental and social management processes to ensure that identified sensitive areas are considered before implementation.
Image

These examples demonstrate that stakeholder engagement is not treated solely as a communication or consultation activity. It is an input to how we assess risks, revise designs, improve implementation, shape social contribution programs and, where necessary, make preventive decisions to avoid potential impacts before they occur.

Our approach is informed by internationally recognized frameworks, including the International Financial Institution (IFI) standards, GRI Standards (GRI 2-29), the European Sustainability Reporting Standards (ESRS SBM-2) and the IFRS Sustainability Disclosure Standards.

Stakeholder-Informed Decision-Making: Cancellation of Arturna-II WPP

As part of the YEKA-2 Wind Power Plant portfolio in Muğla, Enerjisa Üretim conducted comprehensive environmental and social assessment studies for the planned wind power projects and their associated facilities, including electricity transmission lines. These studies were supported by independent consultants and included baseline surveys, field observations, technical reviews, and stakeholder engagement with local residents and relevant public authorities.

During the assessment process, several unregistered but potentially sensitive areas were identified as potential cultural heritage risk zones. Arturna-II WPP stood out as the project with the most critical potential sensitivity. In response, Enerjisa Üretim expanded the assessment through additional site visits, design reviews, and LiDAR-assisted drone surveys carried out with in-house equipment and personnel.

Stakeholder engagement was central to this decision-making process. Consultations with residents helped capture site-specific knowledge and community perceptions regarding cultural heritage sensitivities, land use and local values. Dialogue with relevant state authorities supported the evaluation of potential risks and ensured that the authorities were formally notified of the identified potential cultural heritage risk areas (some would be dating back to Hellenistic era). These engagements strengthened the quality of the assessment by combining technical evidence with local knowledge and regulatory perspective.

The output of the assessment also showed the relationship between potential sensitive areas and planned project components. The findings were reviewed together with stakeholder feedback, authority engagement outcomes and alternative design options as part of the project decision-making process.

Example of a potential cultural heritage sensitivity identified in the Arturna-II WPP project area, assessed together with authority engagement and technical reviews as part of the project cancellation decision.

Following these reviews, Enerjisa Üretim decided to cancel the Arturna-II WPP Project in order to avoid potential cultural heritage-related impacts. Rather than treating stakeholder engagement as a procedural step, this decision demonstrates how early dialogue, official authority engagement and technical assessment can jointly shape material investment decisions and prevent potential impacts before they occur.

A similar preventive approach was applied within the Arturna WPP Project, where one potential sensitive area identified during the assessment process was found to overlap with the planned Turbine T1 location. After reviewing alternative siting options, Enerjisa Üretim decided to cancel the T1 location to avoid potential impacts.

All cultural heritage-related findings and risk considerations were communicated internally, and construction planning has been aligned with identified sensitive areas to ensure the protection of potential cultural assets. The Arturna-II case demonstrates Enerjisa Üretim’s commitment to responsible project development, the value of local cultural heritage, and transparent stakeholder-informed risk management approach.

OUR STAKEHOLDER UNIVERSE

HOW STAKEHOLDER INPUT SHAPES DECISIONS

Stakeholder priorities are captured through surveys, workshops, focus groups, consultations, engagement meetings, grievance channels and satisfaction assessments. These inputs help us understand stakeholder expectations and identify themes that are relevant to both stakeholders and the business, including renewable capacity growth, emissions intensity reduction, energy security, system reliability, water and biodiversity management, occupational health and safety, responsible transition, supply chain resilience, digital and operational resilience, customer decarbonization needs and local community impacts. Stakeholder perspectives are also considered alongside external ESG assessments, sustainability indices, sector developments and reporting standards, providing additional context for evaluating sustainability-related impacts, risks and opportunities.

Stakeholder input is integrated into our risk and opportunity analysis and enterprise risk management processes and informs decision-making across the business. Investor and lender expectations related to decarbonization, transition planning, sustainable finance and disclosure quality contribute to the ongoing development of our renewable growth strategy, emissions intensity reduction efforts and broader portfolio transformation activities. Community priorities relating to employment, environmental stewardship, biodiversity, land use and local development are considered in project design, environmental and social management processes and just transition initiatives, particularly in transition-sensitive regions. Supplier and contractor engagement contributes to the continuous development of procurement standards, ESG risk management approaches, occupational health and safety practices, technology deployment and supply chain resilience planning. Together, these insights help validate priorities, strengthen implementation approaches and support informed decision-making across the business.

In 2025, stakeholder and beneficiary engagement provided valuable perspectives that supported the continued development and refinement of a number of strategic and social initiatives. Community engagement around the Tufanbeyli Energy Base contributed to the shaping of our just transition approach, while an independent social impact assessment covering five thematic areas across eastern and western operational regions provided additional insights that informed program design, capacity-building components and the development of a long-term social contribution roadmap aligned with our 2040 ambitions. Investor dialogue on decarbonization and transition-related expectations helped inform the ongoing evolution of the Climate Transition Plan, while employee feedback gathered through satisfaction surveys and town halls contributed to enhancements in talent development and wellbeing programs.

Together, these engagement processes helped validate priorities, strengthen implementation approaches and ensure that initiatives remained responsive to stakeholder expectations and local needs.

Sustainability-related impacts, risks and opportunities identified through stakeholder engagement are integrated into relevant governance, risk management and decision-making processes according to their nature and significance. This supports a continuous feedback loop in which stakeholder dialogue informs assessment and prioritization; assessment informs governance and strategy; strategy guides implementation; and outcomes are communicated back to stakeholders through ongoing engagement and reporting processes.

FROM STAKEHOLDER ENGAGEMENT TO DOUBLE MATERIALITY

Stakeholder engagement forms a key input into our Double Materiality Assessment. Through ongoing dialogue and structured engagement activities, stakeholder perspectives help identify and assess sustainability-related impacts, risks and opportunities across our own operations, upstream and downstream value chain, and the wider energy system in which we operate.

These insights are considered alongside internal assessments, sector developments, regulatory trends, peer benchmarks, reporting standards and business priorities to support the identification and prioritization of material topics. This process helps ensure that our Double Materiality Assessment reflects both impact materiality, how our activities affect people and the environment, and financial materiality, how sustainability-related matters affect our business, strategy and financial performance.

The outcomes of the assessment inform our governance, strategy, risk management, target-setting, investment planning and reporting processes, helping ensure that sustainability-related impacts, risks and opportunities are integrated into our long-term value creation approach and communicated transparently to stakeholders.

For a detailed description of the Double Materiality Assessment materiality assessment methodology, including the stakeholder groups consulted, assessment criteria applied and material topics identified, please refer to the Double Materiality Assessment section of this report.

UNDERSTANDING WHAT MATTERS MOST

At Enerjisa Üretim, we determine our sustainability priorities through a double materiality assessment in accordance with the European Sustainability Reporting Standards (ESRS). This assessment considers sustainability matters from two complementary perspectives. Impact materiality (inside-out) evaluates our actual and potential impacts on people and the environment. Financial materiality (outside-in) assesses how sustainability-related risks and opportunities may affect our business, strategy and long-term value creation. In 2025, we updated our Double Materiality Assessment (DMA) to reassess our current and potential sustainability-related impacts, risks and opportunities (IROs) across our value chain and operating environment. The assessment provides a structured basis for identifying the sustainability matters that are most relevant to our business and stakeholders, while supporting strategic decision-making, risk management and sustainability reporting processes.

Detailed methodology, ESRS taxonomic mapping and the consolidated register of underlying impacts, risks and opportunities are provided in the ESRS-Aligned Risk, Opportunity and Impact Assessment Annex.

OUR METHODOLOGY

The assessment combines impact materiality (inside-out) and financial materiality (outside-in) through a consistent ESRS-aligned methodology. Sustainability matters are classified as material where they exceed the defined threshold under either dimension or both. The 2025 assessment also introduced separate gross and net scores to distinguish inherent impacts from residual impacts after mitigation measures. The methodology was implemented through four steps outlined below:

Step 1 — Building the Sustainability Universe
As the first step, we developed a comprehensive universe of potential sustainability topics by reviewing global trends, regulatory developments, sector dynamics, stakeholder expectations and international reporting frameworks. In this process, we considered: ESRS Double Materiality Implementation Guidance IFRS S1 and IFRS S2 Sustainability Disclosure Standards SASB Standards relevant to the electricity generation sector World Economic Forum Global Risks Report TCFD (Task Force on Climate-related Financial Disclosures) TNFD (Taskforce on Nature-related Financial Disclosures), including the LEAP approach Science Based Targets Network (SBTN) guidance

The assessment also incorporated the outcomes of previous materiality assessments, stakeholder feedback collected throughout the year, community engagement activities, investor and lender expectations, sector developments and emerging sustainability trends. The 2025 update also considered changes since the previous assessment cycle, including regulatory developments, evolving stakeholder expectations, sector transition dynamics and updates in business priorities.

Step 2 — Identification of Impacts, Risks and Opportunities
The identified sustainability matters were subsequently mapped against relevant ESRS topical standards and disclosure requirements to ensure alignment with European sustainability reporting expectations.

The assessment was conducted at the level of impacts, risks and opportunities, rather than solely at topic level. Identified sustainability matters were broken down into specific actual and potential impacts, risks and opportunities, which were individually assessed and scored. The materiality conclusion at topic level was then determined based on the aggregation of the underlying IRO assessment results.

Step 3 — Stakeholder Engagement
Stakeholder engagement formed a key input to our assessment process. Perspectives were gathered from a broad range of internal and external stakeholders, including affected stakeholders and users of integrated reporting. These included employees, senior management, shareholders, subsidiaries, financial institutions, customers, suppliers, local communities and academic representatives.

Stakeholder feedback was collected through surveys and ongoing engagement mechanisms and subsequently integrated into the assessment using a predefined scoring methodology. These perspectives were complemented by internal assessments, regulatory developments, sector trends and business priorities. Building on these inputs, we assessed sustainability-related impacts, risks and opportunities across our full value chain, covering upstream activities, our own operations and downstream activities.

Step 4 — Assessment and Scoring
A cross-functional assessment workshop involving approximately 65 participants from 35 departments was conducted to evaluate identified environmental, social and governance-related impacts, risks and opportunities. Subject matter experts reviewed, challenged and refined the assessment outcomes to ensure completeness, consistency and alignment across business functions. Assessment outcomes were subsequently calibrated and reviewed through expert discussions and senior management validation.

Impact materiality was assessed in line with ESRS methodology. Actual and potential positive and negative impacts were evaluated based on their scale, scope and irreversibility, while likelihood was additionally considered for potential impacts. Financial materiality was assessed by evaluating the current and potential effects of sustainability-related risks and opportunities on our revenues, profitability, cash flows, access to finance, cost of capital, assets and liabilities, and business continuity. Risks and opportunities were assessed based on their magnitude and likelihood, taking into account existing mitigation measures and management practices.

For both impact and financial materiality, predefined scoring scales and decision thresholds were applied to support consistency across the assessment. Topics were classified as material where one or more underlying IROs exceeded the defined impact and/or financial materiality threshold. Borderline cases were subject to additional expert review, calibration and management validation to ensure completeness, consistency and methodological robustness.

The assessment considered short-term (0–5 years), medium-term (5–10 years) and long-term (10–30 years) time horizons to evaluate how sustainability-related matters may influence both our impacts and financial performance over time. These time horizons reflect the characteristics of the energy generation sector, including asset life cycles, investment planning horizons, regulatory developments and long-term transition dynamics.*

*The time horizons applied here reflect the framework in place when the Double Materiality Assessment was conducted. Other corporate risk and opportunity disclosures, including sustainability and climate-related matters, may apply refined horizon definitions. The Double Materiality Assessment will be reviewed against these horizons in future assessment cycles.

ASSESSMENT OUTCOMES

The assessment identified sustainability-related impacts, risks and opportunities across our value chain and operating environment. These were evaluated across short-, medium- and long-term time horizons and mapped across upstream activities, own operations and downstream impacts.

Following the assessment, calibration and management validation process, 13 topics exceeded the established materiality threshold and were therefore classified as material for Enerjisa Üretim. These topic-level conclusions were derived from the underlying assessment of material impacts, risks and opportunities.

These topics represent the sustainability matters that have the most significant actual or potential impacts on people and the environment or are expected to influence Enerjisa Üretim’s financial performance, enterprise value creation and long-term resilience.

The assessment results demonstrate that environmental stewardship, workforce wellbeing, responsible governance, operational resilience and energy transition-related topics represent the most significant sustainability considerations for Enerjisa Üretim from both impact and financial materiality perspectives.

Together, these findings form the basis of our sustainability strategy, target-setting process, risk management approach and reporting priorities.

To ensure alignment with EU sustainability reporting requirements, material topics have been mapped against the relevant ESRS topical standards (E1–E5, S1–S4 and G1). Detailed information on identified impacts, risks and opportunities, including their ESRS alignment, value chain position and time horizon, is provided in the ESRS-Aligned Risk, Opportunity and Impact Assessment section of the Annexes.

The Double Materiality Assessment will be reviewed periodically to reflect evolving regulatory requirements, stakeholder expectations, market developments and strategic priorities.
