Shareholders' Nomination Board

The purpose and task of the Shareholders' Nomination Board is to prepare and present the General Meeting of Shareholders with the proposals on the remuneration of the Board of Directors, and the number of its members and on the composition of the Board of Directors. In addition, the Shareholders' Nomination Board identifies possible successor candidates to the Board members.

In accordance with the Charter of the Shareholders' Nomination Board of Fortum, the Nomination Board consists of three members. The members are appointed by the Company's three largest shareholders, who are each entitled to appoint one member. The three largest shareholders are determined on the basis of the holdings in the shareholder register maintained by Euroclear Finland Oy as of the first working day of June of each year. The members of the Shareholders' Nomination Board are appointed annually, and their term of office expires at the time of the election of the next Shareholders' Nomination Board. The Chair of the Company's Board of Directors acts as an expert to the Shareholders' Nomination Board without the right to vote. In the event that a shareholder does not wish to exercise its right to appoint a representative, it shall pass the right to the next largest shareholder. The Shareholders' Nomination Board forwards its proposals for the AGM to the Board of Directors. The Chair of the Board of Directors shall convene the Shareholders' Nomination Board to its first meeting, which shall elect its Chair by majority vote from amongst its members. The Nomination Board shall convene at the notice of its Chair. The Nomination Board may also engage the services of an external consultant in its search for suitable candidates for the Board of Directors or for evaluation of the remuneration of the Board of Directors.

Diversity Principles for the Board of Directors

In preparing its proposals concerning the nomination of board members, the Shareholders' Nomination Board prepares and applies diversity principles to the Board of Directors in line with the Finnish Corporate Governance Code 2025. The diversity principles include, among others, that the board composition shall include expertise from the geographical areas where Fortum conducts its business, the underlying profession of the board members shall include such competences that support the implementation of Fortum's strategy and that enable the board members to challenge management decisions and to exercise an overseeing role. In addition, the board composition shall include both genders. The diversity principles and their implementation are reviewed by the Shareholders' Nomination Board annually.

The Shareholders' Nomination Board applied the diversity principles in preparing the proposal concerning the nomination of the board members for the AGM 2025 and for the upcoming AGM 2026.

The goal of the Shareholders' Nomination Board is to find candidates for potential board members meeting the requirements set by the international nature of the Company's business emphasising experience gained in a CEO level management position in international business, and strong expertise in sustainability, energy industry, and digitalisation, in particular. The Shareholders' Nomination Board has deemed that both the current board composition and the board member candidates proposed to be elected by the AGM 2026 possess all the competences defined in the diversity principles in a well-balanced manner.

Internal control and risk management at Fortum

Internal control and risk management at Fortum cover the strategic, operational, financial and hazard risks. They are designed to provide reasonable assurance on the quality and regulatory compliance of financial and sustainability reporting, and to ensure that Fortum complies with the applicable laws and regulations. Fortum's internal control framework is based on the framework introduced by the Committee of Sponsoring Organisations of the Treadway Commission (COSO). Fortum's risk management framework follows the principles of both the ISO 31 000 and the

COSO ERM risk management standards.

Fortum's values set the foundation for risk management and internal control. Fortum has a decentralised organisational model, and a substantial degree of authority and









responsibility over risk management and internal control has been delegated to the business units. Fortum applies the "Three Lines of Defence" model, as illustrated in the graphic below.

Group Accounting is responsible for the overall control framework and internal controls methodology, and it also coordinates and develops the monitoring process, as well as performing validation actions. Internal controls are reviewed each year to ensure that any changes in the risks, processes, systems, and organisational responsibilities are reflected in the design of the controls. Group Accounting supports the business units in the assessment and development.

Fortum has also defined five core governance processes to enable efficient governance in areas that have the most significant influence on the successful execution of Fortum's strategy. The core governance processes are strategy and

capital allocation, investment management, performance management, risk management, and talent management.

Fortum's internal control system also covers controls over sustainability reporting. See further information in Sustainability Statement in Fortum's Operating and Financial Review included in Fortum Financials 2025.

Risk management principles and the Group Risk Policy



Fortum's Board of Directors approves the Group Risk Policy that defines the objective and the key principles and responsibilities for risk management in Fortum Group. The Group Risk Policy also includes a description of the main features of the risk management process applicable to all processes in Fortum. A more detailed description of risk management can be found in Operating and Financial Review included in Fortum Financials 2025.

Internal controls over financial reporting

Controls over financial reporting aim to ensure that financial reporting is relevant and faithfully represents the events during the reporting period, and that the financial reporting is compliant with applicable laws and regulations.

The standards, processes and structures of internal control are set through Group policies, Group instructions and the Fortum internal control framework. The guidelines and reporting instructions for finance processes include the Fortum Accounting manual and technical reporting instructions, as well as the Investment manual and reporting instructions. Finance Network meetings are held regularly to notify about upcoming changes in the IFRS standards, new





accounting policies, changes in sustainability reporting, and other reporting requirements.









Controls over financial reporting consist of general control requirements defined based on risk assessment and include controls regarding instructions, approval rules, validation and reconciliation, analysis, management reviews, and compliance checks. Each finance function defines their specific controls based on these general requirements. Controls and the Performance management core governance process cover, e.g., the analysis of the business performance, including e.g. volumes, revenue, costs, working capital, and asset valuations. The stream lead of the finance process ensures the consistency, and develops the general control requirements. The general IT controls support the financial reporting controls in areas such as access control, back-up and restore management.









Maturity assessment of the key controls is performed annually as a self-assessment, signed off by the respective VPs of the business units and verified with a validation process conducted by the stream lead of the finance process and Group Accounting being responsible for the overall internal controls framework. The results and identified improvement actions are reported to the Fortum Leadership Team and to the Audit and Risk Committee on an annual basis. Internal control design and operating effectiveness are also assessed as part of the audits carried out by Internal Audit.

Auditing

Internal audit

The purpose of the Internal Audit function is to provide independent and objective assurance, designed to improve Fortum Group's operations. Internal audit provides a disciplined and systematic approach in examining and evaluating the appropriateness and effectiveness of the Group's management and corporate governance processes, the internal control system, risk management, and operational processes. The operating principles of internal audit are defined in the Internal Audit Charter, approved by the Audit and Risk Committee of the Board of Directors.

Internal audit assignments are conducted in accordance with a risk and assurance based annual plan approved by the Audit and Risk Committee of Board of Directors and focusing on the key risks and core processes in Fortum operations.

The internal audit reports functionally to the Audit and Risk Committee, and administratively to the Fortum Chief Financial Officer. It reports on the results of the conducted audits, related findings and recommendations to the responsible business unit, area and function management for corrective actions. A summary of the audit results and the status of the management's implementation of the agreed corrective actions to address the findings identified in the audits are regularly reported to the Audit and Risk Committee and the Fortum Leadership Team. All audit reports are also provided to the external auditor.

The Internal Audit function cooperates regularly with the Group's other assurance functions, such as Risk, Internal Control, Compliance and Ethics, Safety and Security.

External audit and sustainability reporting assurance

The Group and the parent company have one external auditor and a sustainability reporting assurance provider. The external auditor and the sustainability reporting assurance provider are both elected by the AGM. The term of office of

the auditor and the sustainability reporting assurance provider is one financial year.

Fortum AGM 2025 resolved to re-elect audit firm Deloitte Oy as the Company's external auditor and sustainability reporting assurance provider for the financial year 2025, with Jukka Vattulainen, APA, ASA, as the principal auditor and the principal authorised sustainability auditor.

In addition, AGM 2025 resolved to elect KPMG Oy Ab as the Company's external auditor and sustainability reporting assurance provider for the financial year 2026, with Kirsi Jantunen, APA, ASA, as the principal auditor and principal authorised sustainability auditor.

AGM 2025 further resolved that the fees of the auditors and of the sustainability reporting assurance providers elected for the financial years 2025 and 2026 would be paid pursuant to the invoices approved by the Company. The fee paid to the auditor and the sustainability reporting assurance provider for services rendered and invoiced in 2025 totalled approximately EUR 2.2 million. In addition, the audit firm was paid a total of approximately EUR 0.0 million in fees for non-audit and advisory services rendered and invoiced.

Compliance at Fortum

Code of Conduct

Fortum's Code of Conduct is based on the shared corporate values which form the ethical basis for all work at Fortum. As a responsible corporate citizen, Fortum strives for the highest ethical conduct and integrity. In addition to Fortum employees, the Code of Conduct applies to members of the Board of Directors and anyone representing Fortum. In addition, companies affiliated to Fortum are expected to respect these principles.

Fortum's Code of Conduct builds on several international agreements and initiatives. It sets the rules that Fortum follows and in accordance with which Fortum does business. It also defines the principles for how Fortum treats colleagues

and interacts with customers, vendors, partners, communities and governments. Renewed in 2024, the Code of Conduct reflects Fortum's strategy, the strengthening of the cultural priorities and Fortum's journey to drive decarbonisation in industries.

In addition, Fortum has a separate Supplier Code of Conduct in place, and the Company expects its business partners to act responsibly and to comply with the requirements set forth therein. Fortum assesses the performance of its business partners with supplier qualification and supplier audits.

Compliance programme

Fortum applies a group-wide compliance programme which covers the key areas of regulatory compliance, privacy and business ethics.

The Group Compliance function constantly seeks to improve the compliance programme, to mitigate risks, and to ensure a comprehensive compliance coverage in all Fortum's business areas and regions.

The key actions and focus areas in 2025 were related to regulatory compliance, further development of Fortum's third-party risk management processes, enhancing the use of digital compliance tools and increasing management reporting with focus on privacy risks. Targeted trainings were organised to further strengthen Fortum's ethics and compliance culture and awareness. To understand how well the programme and actions work in practice, Compliance and Ethics also launched a compliance questionnaire in 2025.

Director Legal, Compliance and Ethics as Group Compliance Officer and Chief Privacy Officer leads the Compliance team. Compliance is a part of the Legal function in Fortum, but it also has a parallel independent reporting line directly to the Audit and Risk Committee. In addition, Director Legal, Compliance and Ethics reports regularly on compliance matters to the Board of Directors, FLT and the FLT Risk Committee.

Fortum has a zero-tolerance policy for corruption and bribery. Fortum has anti-corruption procedures in place, including

prevention, oversight, reporting and enforcement based on the requirements prescribed in international legislation. The key policies addressing corruption and bribery include Fortum's Code of Conduct, Supplier Code of Conduct, Business Ethics Instructions, Sustainability Policy and SpeakUp Policy. The Group Compliance function is responsible for the investigation of cases of bribery and corruption, responding to allegations, and providing training.

Fortum encourages reporting of all potential non-compliance cases through designated reporting channels. In addition to reporting any suspected misconduct to employees' own supervisors, other management members, People function or to Group Compliance, Fortum employees and other stakeholders can also confidentially report any suspicions of misconduct by using the "SpeakUp" channel in their own language on Fortum's internal and external websites. The "SpeakUp" process at Fortum also ensures compliance with the EU Whistleblowing Directive.

Insider administration

As a publicly listed company, Fortum complies with the EU Market Abuse Regulation (MAR), the EU Regulation on

wholesale Energy Market Integrity and Transparency (REMIT) and related regulation. In addition, Fortum complies with the Guidelines for Insiders of Listed Companies issued by Nasdaq Helsinki, and has internal insider rules in place. The internal insider rules are available to all Fortum employees, and they are updated on a regular basis. Internal training sessions are arranged on the insider rules for the persons concerned. The coordination and control of the insider affairs are among the responsibilities of the EVP Legal, General Counsel.

The persons discharging managerial responsibilities at Fortum and the persons closely associated with them are under a duty to disclose their transactions made with Fortum's financial instruments and emission allowances in accordance with MAR to the Finnish Financial Supervisory Authority and to the Company. The transactions have to be notified to the Finnish Financial Supervisory Authority within three business days from the conduct of the transaction in question. Fortum

publishes these transactions through stock exchange releases. Fortum has defined the members of the Board of Directors of the Company and the Fortum Leadership Team members as the persons discharging managerial responsibilities referred to in MAR.

Furthermore, the persons discharging managerial responsibilities at Fortum and the persons closely associated with them may not trade in Fortum's financial instruments on their own account or for the account of a third party, directly or indirectly, for a closed period of 30 days prior to the publication of any interim reports and financial statements (the so-called Closed Window). Under the restriction, it is also not allowed to disclose the financial information, or to advise anyone in trading with Fortum's financial instruments. In accordance with the recommendation of Nasdaq Helsinki, the trading restriction has been extended to apply to certain other separately designated members of Fortum personnel who participate in the preparation, drawing-up and disclosure of Fortum's interim reports and financial statements, or who in connection with their specific duties, have regular access to sensitive unpublished financial information relating to Fortum. All of these persons have been personally informed about the trading restriction and the related obligations, and training sessions are organised for the persons concerned.

Event-based insider lists are established at Fortum on a case-by-case basis separately for specific projects, and they

are administered strictly in accordance with MAR. Any event-based insiders are under the trading restriction described above until the termination of the project and/or disclosure of the inside information.

Any suspected violations against Fortum's internal insider rules or the securities and commodity trading regulations, such as MAR and REMIT, should be reported, depending on the suspected breach, either directly to the EVP Legal, General Counsel or the Group Compliance Officer, or alternatively, by using the "SpeakUp" channel described above.

Related party transactions

Related party transactions are regulated by the Finnish Companies Act, the Finnish Securities Markets Act, and the Corporate Governance Code 2025, as well as the IAS 24 Related Party Disclosures. Fortum has a specific framework in place for the identification, assessment, approval, monitoring and reporting of the Company's related party transactions.

In accordance with the Finnish Companies Act, the Board of Directors is responsible for the monitoring and assessment of related party transactions. The Audit and Risk Committee of the Board of Directors assists the Board in its task by preparing the matters. As part of its duties, the Audit and Risk Committee monitors the related party transactions concluded by Fortum in accordance with the Company's established reporting practices.

Fortum discloses information regarding related party transactions on an annual basis as part of the notes to the Company's Consolidated Financial Statements. In addition, as required by law, Fortum discloses the details of any related party transactions that are material to the shareholders by issuing a stock exchange release.
