Letter from the Chairman of the Remuneration Committeen Dear Shareholders, For Eni, 2023 was a year of excellent results achieved in an uncertain and volatile environment, in which the company successfully continued on its path of industrial transformation, in line with its adopted strategy, focused in particular on the energy transition and decarbonisation. At the same time, Eni continued to pay the utmost attention to its People, including through the establishment of an extraordinary plan to support employees, which provided for a series of salary measures (an extraordinary one-off payment, fuel bonus, discount on gas and electricity utilities), in consideration of the loss of purchasing power caused by high inflation. In this context, I am also pleased to announce the introduction – in the Eni Remuneration Policy – of a Employee Stock Ownership Plan aimed at all employees, which will be implemented in the period from 2024-2026. This Plan made it necessary to update the Policy for 2024, which is then submitted for approval to the Shareholders' Meeting of 15 May 2024, together with the related Information Document. The purpose of the Employee Stock Ownership Plan is to strengthen Eni people's sense of belonging to the company and promote their participation in the company's objectives and growth in value, in line with shareholders’ interests. Remuneration Policy for 2024 First of all, the new Remuneration Committee played its role, both proactive and advisory, in the application of the 2023-2026 Remuneration Policy, drafted at the end of the previous Board term, in line with the recommendations of the Corporate Governance Code, to which the company adheres. The decision to launch the Employee Stock Ownership Plan entailed the need to amend the Policy, in relation to the participation in the Plan of the Chief Executive Officer and General Manager and of Managers with Strategic Responsibilities (limited to the symbolic grant of one share). Against this backdrop, the Committee, having appreciated the high approval level for the 2023-2026 Policy, which exceeded 90%, decided to continue along the line outlined by the previous Board and Shareholders' Meeting and not propose any further changes of substance. Therefore, the Policy for 2024 keeps the structure and remuneration levels of directors and management unchanged, with the only substantial change being the Employee Stock Ownership Plan. Additionally, the Clawback Regulation was updated, using the terms requested in the recent SEC/NYSE regulation, for cases of “accounting restatement”. Shareholder engagement Also for the new mandate, the Committee intends to ensure clear, correct, timely and complete communication with Proxy Advisors and Institutional Investors, with the utmost openness to dialogue and in compliance with the principle of equal information and applicable regulations for the handling and disclosure of documents and information concerning the Company Massimo Belcredi Chairman of the Remuneration Committee

In performing its functions, the Remuneration Committee, immediately after its inauguration, scheduled two rounds of meetings in which I participated directly. The purpose of these meetings was not only to present the new composition of the Committee, but also to engage in dialogue with the market on issues within the Committee's remit, under the terms set out in the Policy for Managing Dialogue with Investors. The Committee intends to continue this dialogue in order to answer questions from investors and receive input on possible future developments in the Policy. Results in 2023 The implementation of remuneration policies in 2023 reflects Eni's excellent financial and operational performance, as well as the implementation of its energy transition and decarbonisation strategy. In particular, the remuneration of the Chief Executive Officer and General Manager is strongly correlated to trends in the company’s results and the value created for shareholders. This evidence shows that Eni's Remuneration Policy contributes to the achievement of strategic objectives and aligns with the interests of shareholders and stakeholders, through an incentive system characterised, both in the short and long term, by balanced metrics – financial and nonfinancial – that also give significant weight to environmental and energy transition objectives. Conclusion It is a pleasant duty for me to thank the other members of the Committee, Cristina Sgubin and Raphael Vermeir, for their constant availability and the contribution they have always made, thanks to their great wealth of professionalism and experience. Dear Shareholders, I leave you to read the Report on the 2024 Remuneration Policy and on Remuneration Paid 2023. I trust in your continued support for the Eni Remuneration Policy, also with respect to the introduction of the Employee Stock Ownership Plan for all employees. March 4, 2024 Massimo Belcredi Chairman of the Remuneration Committee

Introduction The introduction of a Employee Stock Ownership Plan for all employees made it necessary to update the Remuneration Policy for 2024, which will therefore be submitted to the 2024 Shareholders’ Meeting for a vote. This Report on the Remuneration Policy 2024 and on Remuneration Paid 2023 (hereafter, the “Report” or the “Remuneration Report”) was approved by the Board of Directors on April 4, 2024, based on a proposal from the Remuneration Committee, in compliance with current legal and regulatory requirements1 , with an annual duration in relation to potential developments in the regulatory, organisational and business scenarios. The Report includes: • in the first section, a description of the Remuneration Policy for 2024, adopted by Eni SpA (hereafter, “Eni” or the “Company”) for the Directors, Statutory Auditors, Chief Operating Officers and Other Managers with Strategic Responsibilities2 , subordinate to approval by the Shareholders’ Meeting on May 15, 2024 (binding vote), called to approve the annual financial statements at December 31, 2023. The first section also includes a description of the Employee Stock Ownership Plan for all employees, including the Chief Executive Officer/General Manager and Managers with Strategic Responsibilities. Finally, the section describes the corporate bodies involved and the procedures used for the adoption, implementation and possible revision of the Policy and the purposes and general principles that also apply to the remuneration policies of the companies directly and indirectly controlled by Eni3 , with the exclusion of the listed subsidiaries (also jointly controlled), directly required to apply the legislation.

Executive Summary The purpose of the Executive Summary is to provide to the market an overview of the trend in the market results (TSR) and the main indicators of environmental sustainability and human capital (accidents, GHG emissions, pay ratio and minimum wages) and an analysis of pay for performance. The Summary also briefly presents the Remuneration Policy for 2024, the connection with the Eni strategy and the results of the shareholders’ vote on the Remuneration Policy and on its implementation in the previous years. CONTENTS SUMMARY INDICATORS FOR 2023 2024 REMUNERATION POLICY AND CONNECTION WITH THE COMPANY'S BUSINESS MODEL AND STRATEGY RESULTS OF THE SHAREHOLDERS’ VOTE

SUMMARY INDICATORS FOR 2023 (9) The Peer Group consists of: BP, Equinor, OMV, Repsol, Shell and TotalEnergies. (10) Benchmark indices are: Cac 40, FTSE 100, AEX and OBX. TSR: In the 2015-2023 period, Eni delivered a Total Shareholder Return (TSR) of +66.6%, compared to +64.8% for the Peer Group9 , while the FTSE MIB produced a TSR of +98.6%, compared to an average of +56.2% for the peer companies’ respective benchmark stock market indices10. SIR: In 2023, the Severity Incident Rate (SIR) saw a clear improvement with respect to the previous year, thanks to a drop in the most serious injuries. Eni’s Total Recordable Injury Rate (TRIR) also improved on the previous year, still the “best in class” among its Oil & Gas peers (the second in the ranking, TotalEnergies, reported a TRIR of 0.67 in 2022 vs. Eni’s 0.41). Total Shareholder Return Severity Incident Rate CHART 1 – TOTAL SHAREHOLDER RETURN (ENI VS. PEER GROUP AND BENCHMARK STOCK MARKET INDICES) (a) Total recordable injuries/hours worked x 1,000,000. (b) Total recordable injuries weighted for severity/hours worked x 1,000,000. (c) In 2023, this indicator also measures management’s commitment to developing a safety culture, through training, digital tools and innovative projects, verifying the relative implementation and internalisation of the behaviours requested (9) The Peer Group consists of: BP, Equinor, OMV, Repsol, Shell and TotalEnergies. (10) Benchmark indices are: Cac 40, FTSE 100, AEX and OBX.

Net GHG emissions of upstream operated and non-operated equity (Scope 1+2): Net Scope 1+2 Equity Upstream emissions amounted to 8.9 MtCO2 eq. in 2023, down by around 10% with respect to the final figure for 2022 (9.9 MTCO2 eq.). The result benefited from actions to optimise operating management and improve efficiency. The chart also shows the trend for the GHG Scope 1 and 2 emission intensity equity parameter. Total target remuneration of the Eni Chief Executive Officer in 2023 is classified in 10th place with respect to the CEOs of the companies in its Peer Group. The comparison between the trend of TSR and total CEO/GM remuneration in the 2015-2023 period shows a good correlation. CHART 3 – NET GHG EMISSIONS UPSTREAM SCOPE 1 AND 2 EQUITY AND GHG EMISSION INTENSITY SCOPE 1 AND SCOPE 2 UPSTREAM EQUITY (a) Policy target indicated in the Remuneration Reports of the companies, converted to euro at the exchange rate at December 30 Eni Total Remuneration Positioning vs. Peer Group GHG emissions

CHART 5 – PAY FOR PERFORMANCE ANALYSIS (ENI TSR VS. TOTAL REMUNERATION FOR CEO/GM 2015-2023) CEO/GM pay ratio vs. median employee remuneration: below reports the pay ratios between the remuneration of the Chief Executive Officer and General Manager and the median remuneration of employees in Italy and globally, calculated in reference to both the fixed remuneration and the total remuneration11. The total remuneration ratio is increased with respect to 2022, mainly reflecting the change in the Long-Term Stock Incentive granted in 2023, in relation to the increase in the Eni share price at the time of the grant with respect to that when awarded (€15.27 vs. €8.21).CEO/GM pay ratio vs. median employee remuneration TABLE 1 – CEO/GM PAY RATIO VS. MEDIAN EMPLOYEE REMUNERATION Gender pay ratio: the gender pay ratio data for fixed and total remuneration, at the general level and by professional category, (“raw” pay ratio) are shown below. They show a substantial alignment between the salaries of the female and male populations for the Italian and global population, with differences in some categories mainly attributable to a lower presence of women. With respect to the 2022 figures, the data are mainly unchanged with a variation in the Blue collar Italy category due to the entry of female workers from sectors utilising collective bargaining agreements with lower salary references than the reference contract for Eni. Gender pay ratio (11) Total remuneration includes the variable monetary remuneration components and measured benefits.

TABLE 2 – RAW GENDER PAY RATIO(a) (a) The gender pay ratio is calculated as the ratio between the average remuneration of women and the average remuneration of men. Considering the same role level in each professional category, according to the United Nations principle “equal pay for equal work” (Table 3), the alignment between the remuneration of women and men is clearer, with statistically negligible and substantially stable differences over the years. TABLE 3 – GENDER PAY RATIO WITH EQUAL ROLES AND SENIORITY(a) (a) The gender pay ratio is calculated as the ratio between the average remuneration of women and the average remuneration of men.

Minimum Wage: For each country in which it operates, Eni’s policy remuneration standards are well above the legal/contractual minimums, as well as in the 1st decile12 of the local remuneration market. We annually check our positioning in terms of remuneration, adopting any necessary corrective actions. The table shows a comparison between the 1st decile of Eni, the 1st decile of the market and the legal minimum for the main Countries where Eni is present, both expressed as percentages.Minimum wages TABLE 4 – MINIMUM WAGES (a) Ratio refers to fixed and variable remuneration of blue collars or white collars for countries where Eni has no blue collars (market data from Korn Ferry). (b) Minimum salaries as defined by law in the various countries or, if not applicable, in national collective bargaining agreements.(12) The 1st decile represents market practices below which 10% of remuneration is placed.

2024 REMUNERATION POLICY AND CONNECTION WITH THE BUSINESS MODEL AND STRATEGY Eni’s business model is focused on creating value for its stakeholders through a strong presence along the whole energy value chain: from exploration, development and extraction of oil and natural gas, to the generation of electricity from cogeneration and renewable sources, to traditional and bio refining and chemistry, up to the development of circular economy processes and marketing to end markets as well as retail and business customers. Eni aims at contributing, directly or indirectly, to achieve the Sustainable Development Goals (SDGs) of the UN 2030 Agenda, supporting a just energy transition, responding through concrete and economically sustainable solutions to the challenge of combating climate change and giving access to energy resources for all in an efficient and sustainable way. ENVIRONMENTAL SUSTAINABILITY AND ENERGY TRANSITION GOALS (WEIGHT 35%) LTI PLAN 2023-2025 (*) As of December 31, 2023 or in 2023, unless stated otherwise. (**) People involved in local projects could have benefitted from more than one initiative in different areas of opportunity

The Remuneration Policy supports the achievement of the goals set in the Company’s Strategic Plan by promoting, through a balanced use of performance measures in the short and long-term incentive systems, the alignment of senior management’s interests with the priority of creating sustainable value for shareholders over the medium to long-term. The 2023-2025 Long-Term Equity-based Incentive Plan supports the Strategic Plan guidelines by providing a specific environmental sustainability and energy transition goal (with an overall weight of 35%), made up of targets related to decarbonisation, energy transition and circular economy. TABLE 6 – OUR GOVERNANCE PRACTICES WHAT WE DO • Variable incentive plans linked to measurable and predetermined, financial and non-financial, targets, consistent with the Strategic Plan • Pay mix of executive roles characterized by significant long-term components • Performance assessed both in absolute terms and in comparison with industry peers • Long-term incentive vesting periods of no less than 3 years, and lock-up clauses for equity instruments • Malus and clawback clauses in the event of error, bad faith or serious, intentional violations of laws, regulations or of the Code of Ethics and Company rules • Structured engagement plan to respond to the expectations and feedback of our shareholders WHAT WE DON’T DO • No remuneration higher than national and international market benchmarks • No forms of variable remuneration for non-executive Directors • No extraordinary incentives for the CEO/GM • No severance package that exceeds the limits set for by labour agreements and applicable law • No benefits of excessive value, limited to healthcare and pension benefits TABLE 5 – ALIGNMENT WITH THE STRATEGIC PLAN

TABLE 7 – 2024 REMUNERATION POLICY SUMMARY The 2024 Eni Remuneration Policy for Directors, Auditors, Chief Operating Officers and Other Managers with Strategic Responsibilities was approved by the Board of Directors on April 4, 2024 and, keeping remuneration levels unchanged with respect to the previous Policy, has one substantial innovation which is the introduction of a Employee Stock Ownership Plan (ESOP) for all employees.

The 2024 Remuneration Policy for Directors, Auditors, Chief Operating Officers and Other Managers with Strategic Responsibilities was approved by the Board of Directors on April 4, 2024 and, keeping remuneration levels unchanged with respect to the previous policy, has one substantial innovation which is the introduction of a Employee Stock Ownership Plan for all Eni employees, with the aim of strengthening their sense of belonging to the company and participation in the growth of corporate value, in line with the interests of shareholders, as well as to support their purchase power. For the Chief Executive Officer, the Chief Operating Officers, Managers with Strategic Responsibilities and Executives involved in the LTI equity-based Plan, grant has a purely symbolic value, as better described in the dedicated section. Additionally, the Clawback Regulation was updated, using the terms requested in the recent SEC/NYSE regulation, for cases of “accounting restatement”. CORPORATE GOVERNANCE Bodies and parties involved Compliance of Policy with provisions of law and By-laws Bodies and parties involved The Remuneration Policy of members of the Eni Board of Directors, Board of Statutory Auditors, as well as Chief Operating Officers and Managers with Strategic Responsibilities, is defined in accordance with the provisions of law and the By-laws, according to which: • the Shareholders’ Meeting determines the remuneration of the Chairman and other members of the Board of Directors, as well as the remuneration of the members of the Board of Statutory Auditors, at the time they are appointed and for the entire duration of their term (Art. 2389 (1) of the Italian Civil Code and Art. 26 of Eni By-Laws, Art. 2402 of the Italian Civil Code); • the Board of Directors determines the remuneration of the Directors with delegated powers and of those who participate in Board Committees, after examining the opinion of the Board of Statutory Auditors (Art. 2389 (3) of the Italian Civil Code). In line with Eni’s corporate governance system13, the Board is responsible for: • approving the Remuneration Policy described in the first section for members of the Board of Statutory Auditors and Managers with Strategic Responsibilities; • defining the Company’s targets and approving the Company’s performance thereby determining the variable remuneration of eligible Directors with delegated powers; • subject to a proposal of the Chairman in agreement with the Chief Executive Officer, defining the remuneration structure of the Group Head of Internal Audit in accordance with the remuneration policies of the Company, on receipt of a favourable opinion from the Control and Risk Committee and having examined the opinion of the Board of Statutory Auditors. (13) For more nformation regarding the Eni corporate governance system, please refer to the “Corporate Governance and Shareholdings Structure Report” published in the “Corporate Governance” section of the Company website.

In line with the recommendations of the Italian Governance Code, the Board of Directors is supported,by a Committee of independent Non-Executive Directors (the Remuneration Committee) which makes proposals and provides advice on all remuneration issues. The Remuneration Policy is approved by the Board, acting on a proposal of the Remuneration Committee, and is examined by the Shareholders’ Meeting, which is called to express a binding vote on the matter with the frequency required by the duration of the Policy, and in any case at least every three years or in the event of changes. The Board of Directors ensures that the remuneration paid and accrued is consistent with the principles and criteria defined in the Policy, in light of the results achieved and other circumstances relevant to its implementation (Principle XVII of the Governance Code). The Shareholders’ Meeting is required to express an advisory vote on the second section of the Report, devoted to remuneration paid during the year to Directors, Statutory Auditors, Chief Operating Officers and, in aggregate, Managers with Strategic Responsibilities.

Engagement on Remuneration Policy At Eni, we develop interaction with our shareholders and institutional investors regarding remuneration policies, since we are aware of the importance of involving shareholders in the process of defining and monitoring the actual implementation of the Remuneration Policy for Directors and Managers with Strategic Responsibilities, also as recognised by lawmakers when transposing the guidelines contained in the SRD II. Eni offers it shareholders and investors a number of tools and channels for communication: periodic meetings and conference calls and the publication of detailed and complete information on its website (“Remuneration” section14 on the “Governance” page). In particular, an annual Engagement Plan is established, with the main institutional investors and proxy advisors, to help with proposals of Policies to submit for approval at the Shareholders’ Meetings, in line with the Policy for Managing Dialogue with Investors, approved by the Board of Directors. In the context of the Engagement Plan, two cycles of meetings are envisaged, in the autumn and spring, with the participation of the Chairman of the Remuneration Committee, highlighting the importance of direct communication with the market on the issues the Committee is responsible for, within the terms of the Policy for Managing Dialogue with Investors. The Committee examines and monitors the results of engagement activities, in line with the Policy for Managing Dialogue with Investors, ensuring the Board of Directors is adequately informed on developments with reference to dialogue on remuneration issues. Eni Remuneration Committee Composition, appointments and tasks The Eni Remuneration Committee was first established by the Board of Directors in 1996.

POLICY ESTABLISHMENT AND IMPLEMENTATIONIn the first half of 2023, in implementation of the recommendations of the Governance Code, the Committee conducted its periodic review of the adequacy, overall consistency and actual implementation of the Remuneration Policy in 2022, also to identify guideline proposals for the Policy for 2023-2026. In particular, it verified the remuneration benchmarks for Directors with Delegated Powers, for Non-Executive Directors for participation on Board Committees, for members of the Board of Statutory Auditors and Other Managers with Strategic Responsibilities. The Committee also examined, during multiple meetings, proposals regarding the new Long-Term Equity-Based Incentive Plan for 2023-2025 and the Report on the 2023-2026 Remuneration Policy and Remuneration Paid 2022. These proposals were approved by the Board on March 16, 2023 and submitted to the Shareholders’ Meeting for a vote on May 10, 2023. During the same period, the Committee verified the annual results for 2022 for the purposes of implementing the Short-Term Incentive Plan for the Chief Executive Officer and General Manager and defined the 2023 performance targets for the Variable Incentive Plans. Following the renewal of the company bodies, “induction” activities were carried out to inform the new Directors about the cycle of activity for the Remuneration Committee, as well as the principles, structure and remuneration levels established in the Eni Remuneration Policy. Additionally, in line with the approved Policy, the Committee was called on to formalise proposals on the remuneration of Directors with Delegated Powers for the new 2023-2026 term, and to define fees for non-Executive Directors for participation on Board Committees, which were submitted to and approved by the Board of Directors on June 1st. In the second half of 2023, the Committee prepared the proposal for the 2023 implementation of the LTI Equity-Based Plan 2023-2025 for the Chief Executive Officer and General Manager and for critical management personnel for business, preparing the relative Regulations. The Committee also updated the “Clawback Implementation Criteria” regulation, as called for in the Eni Remuneration Policy, to bring it into line with the terms requested in the recent SEC/NYSE regulations. The Committee also examined and approved the update to the note on methodology with reference to neutralising external variables when verifying results, in relation to the consolidation of the new business model. Finally, the Committee began preliminary activities to prepare the Employee Stock Ownership Plan for all employees, to be implemented starting in 2024. ENGAGEMENT In the first half of 2023, the Committee Chairman, as part of the second engagement round, had numerous meetings with the main institutional investors (representing over 13% of share capital) and proxy advisors, to maintain continuous dialogue with reference to the Remuneration Policy and implementation of the same. The Committee examined the voting recommendations issued by the leading proxy advisors and the voting projections prepared with the support of leading consulting firms. Following the renewal of the company bodies, “induction” activities were carried out for the new Directors with reference to the engagement process and activities with the main proxy advisors and institutional investors. During the second half of 2023, the Committee analysed the voting results, comparing them with those of national and European peers, as well as defining the annual engagement plan in view of the upcoming 2024 Shareholders’ Meeting. The first round of meetings, held in July, October and November, included top investors representing around 12% of Eni share capital, as well as the main proxy advisors, in order to introduce the new Remuneration Committee, obtain feedback on the rationales behind the 2023 votes and receive advance notice about voting policies for 2024 if relevantPOLICY ESTABLISHMENT AND IMPLEMENTATION POLICY ESTABLISHMENT AND IMPLEMENTATION • Periodic assessment of the Policy adopted in the previous year using remuneration comparative studies. • Policy establishment and preparation of the Remuneration Report. • Verification and implementation of the existing STI Plan. • Definition of the targets related to the Variable Incentive Plans. • Verification of the existing LTI Plan. • Implementation of the existing LTI Plan. • Monitoring of the regulatory framework and governance and reporting practices in relation to remuneration.

2024 Remuneration Policy approval process (18) For more information on the Code of Ethics, please refer to the Corporate Governance and Shareholdings Structure Report 2023, available on the Corporate Governance website. (19) Policy approved by the Board of Directors on July 28, 2010. In the exercise of its powers, the Remuneration Committee defined the structure and contents of the Remuneration Policy, for the purpose of preparing this Report, specifically at the meetings held on January 22, February 19 and March 4, 2024, in accordance with the recommendations of the Governance Code. In taking its decisions, the Committee reviewed the appropriateness, overall consistency and effective implementation of the 2023 Policy. For the purpose of preparing the Policy, the results of the monitoring of the legislative framework and governance practices on executive remuneration were assessed, with particular regard to developments in the guidelines of institutional investors and feedback received during the engagement meetings held. Lastly, the Committee considered comparative remuneration studies prepared by major international consultants (Willis Towers Watson and Korn Ferry). The 2024 Eni Remuneration Policy for Directors, Auditors and other Managers with Strategic Responsibilities was approved by the Board of Directors, acting on a proposal of the Remuneration Committee, at its meeting of April 4, 2024, at the same time as the approval of this Report. The 2024 Policy does not allow for exceptions in the implementation phase. Any future revision needs will therefore be submitted by the Board, acting on a proposal of the Remuneration Committee, for approval by the Shareholders’ Meeting. The implementation of remuneration policies approved by the shareholders is carried out by corporate bodies delegated to do so, with the support of the competent corporate functions. PURPOSE AND GENERAL PRINCIPLES OF THE REMUNERATION POLICY Purpose The Eni Remuneration Policy contributes to achieving the Company’s strategies, with incentive structures tied to financial, business, environmental and/or social sustainability and energy transition goals, taking a long-term view, taking into account the interests of all stakeholders. Eni’s Remuneration Policy is also consistent with the governance model adopted by the Company and the recommendations of the Corporate Governance Code, in particular providing that the remuneration of Directors, Chief Operating Officers and Managers with Strategic Responsibilities is functional to the pursuit of the sustainable success of the Company and reflects the need to have, retain and motivate people with the skills and professionalism deemed suitable for the role assigned (Principle XV of the Governance Code). Remuneration of members of the Board of Statutory Auditors, illustrated below, was determined, pursuant to Article 2402, Civil Code, by the Eni Shareholders’ Meeting on 10 May 2023. Eni’s Remuneration Policy also contributes to achieving the Company’s mission, by: • promoting actions and behaviours reflecting the Company’s values and culture, consistent with the principles of plurality, equal opportunity, enhancement of individuals’ knowledge and skills, fairness, integrity and non-discrimination, as described in the Code of Ethics18 and Eni Policy “Our people”19, in line with the objectives of the United Nations and according to the principle of “equal pay for equal work”; • recognising roles and responsibilities, results, and the quality of professional contribution, utilising fair and competitive market references able to support a decent standard of living, higher than the legal or contractual minimums in force, as well as the minimum wages of local markets. Policy consistent with recommendations of the Governance Code No exception envisaged Connection with the Company’s strategies Consistency with recommendations of the

General principles In pursuing the above, the remuneration of Directors and key executives is defined in line with the following principles and criteria: Remuneration of managerial roles, CEO/GM and MSRs Total remuneration packages aim for consistency with standard market values applicable for positions or roles of similar level of responsibility and complexity, based on panels of national and international companies comparable to Eni, developed through benchmarking analysis carried out by international remuneration advisors (Recommendation no. 25). The remuneration package is appropriately balanced between a fixed and a variable component, in relation to the strategic objectives and the risk management policy of the Company Recommendation no. 27, letter a). Executive roles with the greatest influence on business performance are characterised by variable remuneration containing a significant percentage of incentive components, particularly long-term awards (Recommendation no. 27, letter a), while the vesting period and/or incentive deferral period are defined over a period of at least three years (Recommendation no. 27, letter d). Remuneration Structure Fixed component and non-monetary benefits congruent with respect to the delegated powers and/ or responsibilities assigned, as well as the experience and skills of the individual in question and market benchmarks with reference to the panel of comparable companies. More specifically, benefits privilege components intended to provide social security and healthcare insurance. The variable component is defined within maximum limits (Recommendation no. 27, letter b) and is intended to anchor remuneration to the strategy and results effectively achieved over the short and long-term, as well as to the interests of stakeholders. Additional payments that be awarded upon termination of employment and/or term of office for executive roles, as well as non-compete agreements that may apply to roles at greater risk of “poaching”, are defined in terms of either a maximum amount or number of years of remuneration, in line with the remuneration received and the performance achieved (Recommendation no. 27, letter f), and in compliance with the protections set out in collective bargaining agreements (CCNL) for executives. Variable incentive systems Short and long-term variable remuneration, linked to pre-established and measurable financial and non-financial targets, consistent with the Strategic Plan and the expectations of shareholders and other stakeholders, intended to combine operational, economic and financial solidity with social and environmental sustainability (Principle XV and Recommendation no. 27, letter c). These targets are defined so as to ensure: • annual performance assessment, on the basis of a balanced scorecard that values the overall business and individual performance, defined in relation to targets specific to each area of responsibility, and for those in charge of internal audit responsibilities, in line with their specific assigned role; • measurement of long-term results both in absolute terms, with reference to the sustainable capacity to generate profit, and in relative terms with respect to the Peer Group, with reference to the capacity to create value with respect to main competitors. Long-term equity-based incentive plans intended to strengthen alignment with shareholder expectations and featuring: three-year vesting periods, pre-established and measurable targets, portion of shares granted locked up for a 2 year period (Recommendation no. 28). Variable remuneration paid pursuant to a detailed verification process that assesses actual performance against the originally assigned targets, if necessary adjusted to neutralise the effects Consistency with market benchmark Verification of results Adjusted balance between fixed and variable remuneration Fixed Remuneration and Benefits Variable remuneration Severance indemnities and non-compete agreements Financial and non-financial targets Equity-based remuneration plans

of exogenous variables such as the commodity price scenario and exchange rate, as well as events which by their nature are not attributable to management performance, based on the adjustment analysis methodology approved by the Remuneration Committee. In the case that incentives (or the right to the same) have been achieved based on data which is later found to be clearly erroneous (Recommendation no. 27, letter e), or in cases of wilful alteration of the same, a specific malus/clawback Regulation applies, approved by the Board of Directors based on a proposal from the Remuneration Committee, which allows for: non-payment and/or assignment of incentives for which the right to receive has already been vested or is currently in the process of vesting (malus), or the return of all or part of the incentives paid and/or granted (clawback). The Policy provides that the activation of recoupment claims (or withdrawal of incentives awarded but not yet paid) must take place, once appropriate verification has been completed, within three years of payment (or award) in cases of error, and within five years in cases of deliberate intent to defraud. The Regulation can also be applied in cases of termination for disciplinary reasons, including serious and intentional violations of law and/or regulations, the Code of Ethics or Company rules, without prejudice to any action allowed under law for the protection of the Company’s interests. The Regulation has been updated, using the terms requested in the recent SEC/NYSE regulation, for cases of “accounting restatement”. Remuneration of the Chairman and Non-Executive Directors Remuneration of Non-Executive Directors is commensurate with competence, professional qualification and effort required for the tasks assigned and participation on Board Committees set up in accordance with the By-laws (Recommendation no. 29), taking account of relevant market benchmarks, also considering comparable overseas experience; appropriate differentiation between the remuneration afforded to Committee Chairmen, and that of other Committee Members, considering the different roles respectively held regarding coordination of work and relationships with Corporate bodies and managerial teams; Non-Executive Directors are not beneficiaries of variable incentive plans, including equity-based ones, unless decided otherwise by the Shareholders’ Meeting. Remuneration of Members of the Board of Statutory Auditors Fees for members of the Board of Statutory Auditors were determined by the Shareholders’ Meeting on May 10, 2023, based on a proposal prepared by the shareholder of reference, which was based on the fees applied by publicly owned issuers with high capitalisation. In consideration of the role played by the Chairman in coordinating the work and in cooperating with corporate bodies and company departments, a moderate increase was envisaged with respect to the remuneration of the other members. 2024 REMUNERATION POLICY Connection with the Company’s strategies Through its short and long-term incentive systems, the Remuneration Policy supports the realization of the Company’s Strategic Plan, through the definition of targets able to promote the creation of sustainable value for shareholders and other stakeholders in the medium/long-term. In particular, management’s actions are assessed: • in a short-term horizon, in relation to a comprehensive and balanced framework of complementary targets, aimed at ensuring the profitability of the Company as a whole and operational efficiency, the implementation of the energy transition and decarbonisation path, through the incremental installed capacity relating to renewable sources and the reduction of net Upstream GHG emissions Scope 1 and Scope 2 equity, human safety as well as financial strength; Clawback and malus clauses Short-term goals

Long-term goals• in a medium/long-term horizon, with reference to equity-based performance (TSR) directly connected to shareholder interests, and in relation to a series of targeted results in absolute terms and characterised by the centrality of the economic/financial performance (organic Free Cash Flow), integrated by a significant focus on the strategic topics of decarbonisation, energy transition and circular economy. Market benchmarks and remuneration Peer Group For the Chief Executive Officer, the remuneration is assessed against the median value of the remuneration of CEOs of a remuneration Peer Group formed of 18 European companies operating in Eni’s benchmark sectors, taking account of the energy transition process and business transformation strategies. In particular, the companies of the remuneration Peer Group were selected from the energy, utilities and other industrial sectors, comparable with Eni in relation to the business portfolio and/or the organisational size and business complexity. For the Chairman and the Non-Executive Directors, the positioning of remuneration is assessed by comparing similar roles in the Top Italy Peer Group, which is composed of the main companies listed on the FTSE MIB (Assicurazioni Generali, Atlantia, Enel, Intesa Sanpaolo, Leonardo, Mediaset, Mediobanca, Poste Italiane, Prysmian, Snam, Terna, TIM, Unicredit). Long-term goals TABLE 10 – NEW CEO REMUNERATION PEER GROUP Company Country Business activities Energy Utility Chemical Mining Other 1 Shell UK/NL √ 2 TotalEnergies France √ 3 BP UK √ 4 Repsol Spain √ 5 Equinor Norway √ 6 OMV Group Austria √ 7 RWE Germany √ 8 Iberdrola Spain √ 9 E.ON Germany √ 10 ENGIE France √ 11 Enel Italy √ 12 BASF Germany √ 13 Bayer Germany √ 14 Rio Tinto UK √ 15 Anglo American UK √ 16 Volkswagen Germany √ 17 Vodafone UK √ 18 Siemens German

For Managers with Strategic Responsibilities, the positioning of remuneration is assessed by comparing roles of the same level of managerial complexity and responsibility within industrial corporations in national and international markets. Comparisons of remuneration have been conducted with the help of the advisory firms Willis Towers Watson, and Korn Ferry. Employee remuneration and working conditions Eni places its people at the heart of its business strategy and is constantly committed to promoting working conditions in line with the United Nations objectives of wage improvement, reduction of income inequality, promotion of decent job opportunities, gender, generational, ethnic equality etc. according to the “equal pay for equal work” principle. In particular, Eni applies a global integrated remuneration system to all its people, consistent with the reference markets and linked to company and individual performance, in compliance with local legislation. This system adopts remuneration references made up by the market median, guaranteeing fair and competitive remuneration with respect to the role and professional skills and always able to support a decent standard of living, higher than the mere subsistence levels and/or the legal or contractual minimums in force, as well as the market minimum wages, as highlighted by the indicators represented in the Summary. Eni also pays particular attention to the safety, well-being and quality of life of its people, as driving factors for the healthy growth of the Company. This is reflected in Eni’s ongoing commitment in the field of Welfare and in a wide offer of benefits and services in different areas: from health protection to social security coverage, from work and private life balance to training. Employee Stock Ownership Plan 2024-2026 Implementation of a Employee Stock Ownership Plan (ESOP) is planned to begin in 2024, intended for all Eni employees with the aim of strengthening their sense of belonging to the company and participation in the growth of corporate value, in the interests of shareholders, as well as to support their purchase power. The Plan calls for three annual grants in the period 2024-2026 and, in particular, for the two-year period 2024-2025 two free grants of Eni shares for an individual monetary value of €2,000, while for 2026 a "co- investment” which provides, upon the purchase of Eni shares by the employee, the grant of free shares by the company, according to a matching share mechanism of 50% up to a maximum of 1,000 euros. The shares will be subject to lock-up restrictions (three years for shares granted free of charge, annual for any shares purchased by employees). For the Chief Executive Officer and General Manager, Chief Operating Officers and Managers with Strategic Responsibilities and Executives participating in the LTI Equity-Based Plan, the grant is limited to 1 symbolic share. The Plan, approved by the Board of Directors on April 4, 2024, will be submitted for approval to the Shareholders’ Meeting called for May 15, 2024. For more details about the Plan, including the cost and amount of share capital, please see the Information Document prepared in line with Article 114-bis of Italian Legislative Decree 58 of February 24, 1998 and Article 84-bis of the Regulation adopted by Consob with resolution 11971 of May 14, 1999, as subsequently modified and supplemented (Issuers Regulation), published on the Company’s website in the “Governance/Remuneration” section and made available to the public in line with current law.

OFFICERS COVERED BY THE POLICY Chairman of the Board of Directors (20) In consideration of the referral to this Report, in the 2023 Corporate Governance and Shareholdings Structure Report, which is available in the Corporate Governance section of the Company’s website, this information is being published in accordance with Article 123-bis, paragraph 1, letter i), of the Consolidated Law on Financial Intermediation (agreements between companies and directors, members of the control body or supervisory council which envisage indemnities in the event of resignation or dismissal without just cause, or if their employment contract should terminate as the result of a takeover bid). (21) Information provided in accordance with Article 123-bis, paragraph 1, letter i), of the Consolidated Law on Financial Intermediation, as specified under the note above. The 2024 Remuneration Policy for the Chairman establishes, in consideration of the qualifications of the designated person and the findings for remuneration benchmarks, total fixed remuneration of €500,000 gross, unchanged with respect to the previous term, including the remuneration for the role determined by the Shareholders’ Meeting of May 10, 2023 (€90,000 gross) and compensation for the delegated powers (€410,000 gross), approved by the Board of Directors on June 1, 2023. There is also a health and insurance coverage against permanent disability due to injury or illness contracted in the workplace or elsewhere. No specific severance payments are provided for the Chairman, nor do any agreements exist for indemnities in the case of resignation or early termination of office20. Non-executive Directors The 2024 Remuneration Policy for non-executive and/or independent Directors establishes, taking into account the findings for remuneration benchmarks, as well as the skills and experience required to carry out the positions, the following annual remuneration for participation on Board Committees, as approved by the Board of Directors on June 1, 2023 and unchanged with respect to the previous term: • for the Control and Risk Committee, remuneration of €70,000 for the Chairman and €50,000 for other members; • for the Remuneration Committee, remuneration of €50,000 for the Chairman and €35,000 for other members; • for the Sustainability and Scenarios Committee, remuneration of €50,000 for the Chairman and €35,000 for other members; • for the Appointments Committee, remuneration of €40,000 for the Chairman and €30,000 for other members.

No specific severance payments are provided for Non-Executive Directors, nor do any agreements exist for indemnities in the case of resignation or early termination of office21. Board of Statutory Auditors Regulations (Article 123-ter, Consolidated Law on Finance) establish that the first section of the Report must illustrate, clearly and understandably, the company’s remuneration policy for Directors, Chief Operating Officers and Managers with Strategic Responsibilities as well as, without prejudice to that established in Article 2402 of the Civil Code, the members of the control body. Article 2402, Civil Code establishes that annual remuneration of Statutory Auditors, if not established in the By-Laws, shall be determined by the Shareholders’ Meeting at the time of appointment, effective for the entire duration of their term. On this subject, the Corporate Governance Code recommends that the remuneration be appropriate to the responsibilities, skills and commitment (no. meetings and average duration) required by the relevance of the position and the size and sector features of the company. Therefore, the relevance of the tasks carried out is considered, as well as applicable market references, taking into account the size and complexity of the Company.

In the Report on the Remuneration Policy, approved on March 16, 2023, the Board of Directors proposed, taking into account Eni’s listing on the New York Stock Exchange, the evaluation of an increase in the remuneration for the 2023-2026 term, in relation to the increased professional commitments of the Board of Statutory Auditors, also in terms of activities carried out as the Audit Committee for the purposes of SEC compliance. Nonetheless, on May 10, 2023, the Shareholders’ Meeting, based on a proposal from the reference shareholder, approved remuneration of €85,000 for the Chairman and of €75,000 for other members of the Board of Statutory Auditors. Chief Executive Officer and General Manager Fixed remuneration Total Fixed Remuneration (FR) is equal to €1,600,000, of which €600,000 for the position of Chief Executive Officer, which includes the remuneration of €80,000 gross annually for the position of Director approved by the Shareholders’ Meeting on May 10, 2023 and €1,000,000 for the position of General Manager. This remuneration, approved by the Board of Directors on June 1, 2023, has been kept unchanged with respect to the previous term, keeping into account the continuity of the positions and relative delegated powers. This remuneration encompasses any emoluments due for participation in the meetings of the boards of directors of other Eni subsidiaries and/or shareholdings. In relation to the continued nature of the executive employment relationship, the position of CEO is also entitled to an allowance for travel, in line with the provisions of the relevant national collective bargaining agreement (CCNL) for executives of industrial companies and supplementary companylevel agreements. Variable remuneration: short-term incentives with deferral The Policy for 2024 term provides for the maintenance of a Short-Term Incentive Plan with deferral (STI Plan) with the same characteristics as the Plan envisaged in the 2020-2023 Remuneration Policy and unchanged with respect to the 2023-2026 policy approved the previous year. PERFORMANCE CONDITIONS The STI Plan provides for a structure of annual targets distributed across four clusters of equal weighting, consistent with the guidelines defined in the Strategic Plan and balanced against the interests of the various stakeholders. In the Policy clusters, the Remuneration Committee proposes annually to the Board, the adoption of performance targets and parameters consistent with developments in company strategy from the perspective of medium/long-term sustainability. The value of each target is in line with the budgeted figure. The 2024 annual targets approved by the BoD on March 13, 2024 at the proposal of the Remuneration Committee, in the context of the defined policy clusters, are shown in Table 11. TABLE 11 - 2024 TARGETS FOR THE SHORT-TERM INCENTIVE PLAN WITH DEFERRAL 2025 ECONOMIC AND FINANCIAL RESULTS (25%) OPERATING RESULTS (25%) ENVIRONMENTAL SUSTAINABILITY AND HUMAN CAPITAL (25%) EFFICIENCY AND FINANCIAL STRENGTH (25%) INDICATORS • Earning Before Tax • Organic Free Cash Flow INDICATORS • Hydrocarbon production • Incremental installed renewable capacity INDICATORS • GHG net emissions upstream Scope 1 and 2 equity • Severity Incident Rate INDICATORS • ROACE • Net Debt/EBITDA LEVERS • Traditional business value growth • Growth in new sectors LEVERS • Fast track approach to project execution • Organic and inorganic development of renewable energies LEVERS • Decarbonisation • HSE and sustainability LEVERS • Financial discipline in investment projects • Efficiency of operating costs and G&A • Optimisation of working capital

In particular: • the organic Earning Before Taxes (EBT) and Free Cash Flow (FCF) indicators are measures of Eni’s capacity to ensure the profitability of its businesses and ensure investments and shareholder remuneration are sustainable over time, even in particularly challenging situations. In this regard, Eni aims to accelerate the transformation strategy on one hand by increasing the resilience of traditional businesses and their ability to generate cash, and on the other by developing the energy transition businesses that are based on the integration of technologies, new business models and close collaboration with our stakeholders; • the indicators of hydrocarbon production and incremental installed capacity of Renewables make it possible to join upstream business growth with renewable energy development targets connected to the decarbonisation strategy for operations and products; • the Upstream GHG net emissions Scope 1 and 2 equity indicator (tCO2 eq.) reflects Eni’s commitment to reducing GHG emissions, in line with the medium/long-term objectives that will lead the Company to decarbonise all products and processes by 2050. Eni aims to eliminate the carbon footprint associated with its activities, which also involves the gradual reduction of Scope 1 and Scope 2 Upstream emissions; • the Severity Incident Rate (SIR) indicator reflect Eni’s HSE priorities and the central importance of our commitment to individual safety. The prevention and risk minimization are cornerstones of Eni’s operations in our commitment to achieving constant improvements in safety for all workers and to expressing this commitment in the process of assessing the performance of senior management. In particular, use of the SIR focuses Eni’s commitment on reducing serious injuries given that it calculates the frequency of injuries over the number of hours worked, but weighted for the actual severity of the incident. • the ROACE and debt-to-EBITDA indicators measure the Company’s financial discipline and the quality of our financial structure and earnings, which translates into a careful selection of investments, into efficiency and cost control, and into a rapid return on investment. All of these efforts enable us to reinforce our resiliency even during economic downturns. Verification of objectives is done net of the effects of external variables (e.g. oil and gas prices, the Euro/dollar exchange rate), as well as events which by their nature cannot be attributed to management performance, based on the gap analysis method approved by the Remuneration Committee. INCENTIVE MECHANISMS AND LEVELS In line with the general Remuneration Policy principles, the STI Plan with deferral features the same characteristics as in the previous term, described below. Each target is predetermined and measured based on a performance scale of 70-150 points (target = 100) in relation to the weight assigned to each (a score below 70 points implies a performance multiplier of zero). For purposes of the total incentive award, the minimum overall performance is 85 points. In consideration of the need to promote initiatives for developing the business and to further align the remuneration of the CEO/GM with shareholder interests, the option of applying a coefficient of 1.1 to the total score of the annual performance record is also confirmed for operations of particular strategic importance not foreseen in the budget and/or extraordinarily positive annual economic/financial results (with a maximum score for the performance record of no more than 150 points). Also provided for, in a similar manner, is the option of applying a coefficient reducing the final score of 0.9 for adverse scenarios such as to determine extraordinarily negative annual economic/financial results (the performance record score may not be less than 85 points). These circumstances and any application and the corrective coefficient will be assessed by the Remuneration Committee, applying the criteria determined above and submitted for approval to the Board of Directors at the time Eni’s annual performance is verified. Economic and financial targets Operating objectives Environmental sustainability and human capital objectives Efficiency and financial strength objectives Verification of results Incentive mechanisms and levels unchanged

The Total Incentive (TI) is calculated using the following formula: IT = FR X ITarget X M Where FR is total fixed remuneration and “ITarget” is the incentive percentage at target performance level, set to 150% of total fixed remuneration for the Chief Executive Officer, and M is the multiplier related to the performance achieved, as shown in the chart below. The total incentive is divided in: 1) an Annual portion (IA) equal to 65% of the total incentive, paid in the year following the year in which the performance was attained. The values of the Annual portion, depending on the performance achieved, are shown in the table below22; 2) a Deferred portion (ID) equal to 35% of the total incentive subject to additional performance conditions in a three-year period, and payable in the year after said period, as shown in the chart below. (22) The incentive values as a % of fixed remuneration shown in the table were calculated as follows: • Threshold: 83% = 65% x (150% x 85%) • Target: 98% = 65% x (150% x 100%) • Max: 146% = 65% x (150% x 150%) 85% 100% 150% 70 85 100 150 Annual performance Annual multiplier CHART 8 – TOTAL INCENTIVE MULTIPLIER TABLE 12 – LEVELS OF ANNUAL PAYABLE INCENTIVE Annual performance <85 85 threshold 100 target 150 max Annual incentive (in % of Fixed Rem.) 0% 83% 98% 146% PERFORMANCE AND VESTING PERIOD CHART 9 – DEFERRED INCENTIVE - TIMELINE YEAR T  Attribution of STI deferred portion YEAR T+1 YEAR T+2 YEAR T+3  Payment of STI deferred portion Annual incentive payable in the year Deferred incentive subject to further performance conditions during a three-year vesting period

The deferred portion payable (IDE) is determined as follows: I DE = ID X MD Where MD is the final multiplier given by the average of the annual multipliers determined on the basis of the performance achieved by Eni in each year of the three-year period, as shown in the chart below. The values of the payable deferred incentive, depending on the performance achieved in the threeyear period, are shown in the table below23. (23) The deferred incentive values as a % of fixed remuneration shown in the table were calculated as follows: • Threshold: 38% = 35% x (150% x 85%) x 85 • Target: 68% = 35% x (150% x 100%) x 130 • Max: 181% = 35% x (150% x 150%) x 230 Variable remuneration: long-term equity-based incentive The 2023-2025 Equity-based LTI Plan, approved by the Board of Directors on March 16, 2023 and by the Shareholders’ Meeting of May 10, 2023, provides for three annual awards starting from 2023, each with a three-year performance period, in accordance with the chart below, unchanged with respect to the 2023-2026 policy approved the previous year.

PERFORMANCE CONDITIONS The Plan’s performance targets have been further adjusted to developments in Eni’s strategies and to the target of alignment with stakeholder interests. In particular, these objectives are structured as follows: 1) 25% Market Target: linked to Total Shareholder Return (relative); 2) 40% Economic and financial target: Organic Free Cash Flow (absolute); 3) 35% Environmental Sustainability and Energy Transition objective (absolute), structured as follows: 3.1) 10% Decarbonisation objective; 3.2) 15% Energy Transition target, structured according to two indicators both with a weight of 7.5%; 3.3) 10% Circular economy Target. The detailed descriptions of each indicator are given below: 1) Market Target: the difference between the TSR of the Eni share and the TSR of the FTSE MIB index of Borsa Italiana, adjusted by the Eni correlation index, compared with the equivalent adjusted TSR measures for each company of the Peer Group, as shown in the following formula: ΔTSR = TSRCO - (TSRIDX X рCO,IDX) Where: TSRco: TSR of Eni or of one of the companies of the Peer Group; TSRIDX: TSR of the reference stock market index of the company to which the TSRco applies; ρco,IDX: Correlation coefficient between the performance of the shares and the performance of the reference market (FTSE MIB, S&P 500, FTSE 100, CAC 40, AEX, OBX, ATX and IBEX-35). This indicator makes it possible to neutralise the effects of developments in the respective stock markets on the TSRs of each Company, taking into account the correlation index between the stock and the market over the three-year period. The benchmark Peer Group is made up of 6 European companies in the Energy sector characterised by an integrated portfolio and similar energy transition and decarbonisation paths as Eni: Shell, BP, TotalEnergies, Equinor, Repsol, OMV. 2) Economic and financial target: value of the organic Free Cash Flow cumulated in the threeyear reference period compared to the equivalent cumulated value provided for in the first 3 years of the Strategic Plan approved by the Board of Directors in the year of award and kept unchanged during the performance period. 3) Decarbonisation objective: value verified at the end of the three-year period of Upstream net GHG emissions Scope 1 and Scope 2 equity (tCO2eq.), compared with the same value expected in the 3rd year of the Strategic Plan approved by the Board of Directors in the year of attribution and kept unchanged over the performance period. 4) Energy Transition objective: installed capacity of electricity generation from renewable sources (MW) and biojet fuel production capacity (kton) measured at the end of the three-year performance period, compared with the same value expected in the 3rd year of the Strategic Plan approved by the Board of Directors in the year of award and kept unchanged over the performance period. 5) Circular Economy objective: proportion of vertical integration of the agribusiness for biofuel processing compared to the value expected in the 3rd year of the Strategic Plan approved by the Board of Directors in the year of award and kept unchanged over the performance period. Verification of absolute parameters is done net of the effects of external variables (e.g. oil and gas prices, the Euro/dollar exchange rate), as well as events which by their nature cannot be attributed to management performance, based on the gap analysis method approved by the Remuneration Committee.

2023-2025 Long-Term Equity-Based Incentive Plan 2024 Award According to the provisions of the Information Document of the 2023-2025 Long-Term share Plan, available on the Company’s website, table 14 shows the three-year performance levels of the absolute objectives of the first award of the Plan (award 2024, with performance period 2024-2026). The mentioned performance targets were approved by the Board of Directors, on the proposal of the Remuneration Committee, at the meeting of March 13, 2024. INCENTIVE MECHANISMS AND LEVELS The annual award of shares is calculated using the following formula: No. of shares awarded = FR X %ITarget /PAttr Where FR is total fixed remuneration, ITarget is the incentive percentage at target performance level (150% of the fixed remuneration for the Chief Executive Officer) and PAttr is the price of the award calculated as the average of the daily official prices (source: Bloomberg) recorded in the 4 months before the month in which the Board of Directors approves the award to the Chief Executive Officer and the Plan rules. The grant of shares at the end of the three-year vesting period is determined using the following formula: No. granted shares = no. awarded shares x Mf In which the final multiplier Mf is equal to the weighted average of the multipliers of each indicator. For the relative indicator linked to the TSR, the multiplier may be between zero and 180%, with a threshold set at a median level, in accordance with the scale shown below.

For absolute targets (Economic and Financial, Decarbonisation, Energy Transition and Circular Economy objectives), the result will be measured based on a partial multiplier between zero and 180% determined as a function of performance, as in the following chart: The table below shows the thresholds, targets and maximum monetary value of shares (as a percentage of fixed remuneration) grantable to the Chief Executive Officer at the end of the vesting period, net of any effects due to changes in the share price24. The 2023-2025 Plan Rules envisage for the Chief Executive Officer and Executives in service, that 50% of the shares awarded at the end of the vesting period are to remain restricted for 2 years from the granting date. For the CEO/GM, this would be equivalent, in the event of shares granted annually equal to the value of the LTI awarded, to a shareholding objective (achievable within 2 years) equal to 1.5 times the fixed remuneration. In the event of early termination for the Chief Executive Officer, due to resignation and not justified by a substantial reduction in powers or of termination for just cause, all rights to the award and payment of incentives shall lapse. In the event of termination related to expiry of the term of the Board of Directors without renewal, the grant of Eni shares of each award will be prorated with respect to the period of permanence in office, according to the results verified over the same period. (24) The incentive values as a % of fixed remuneration shown in the table were calculated as follows: • Threshold: 60% = 150% x 40% • Target: 183.75% = 150% x 122.5% • Max: 270% = 150% x 180% CHART 12 – PERFORMANCE SCALE - MULTIPLIER FOR ABSOLUTE PARAMETERS 200% 180% 160% 140% 120% 100% 80% 60% 40% 20% 0% 180% 130% 80% Performance Target Minimum Performance Maximum Performance TABLE 16 – VALUE LEVELS OF GRANTED SHARES Average 3-year weighted performance <40 40 threshold 122.5 target 180 max Value of shares (in % of Fixed Rem.) 0% 60% 183.75% 270% Shareholding Policy Pro-rata mechanism in case of consensual termination of the CEO

Malus/Clawback (25) Information also provided in accordance with Article 123-bis, paragraph 1, letter i), of the Consolidated Law on Finance. All variable incentives in favour of the Chief Executive Officer are subject to the malus/clawback clauses envisaged in Eni’s Remuneration Policy, described in the General Principles chapter. Non-monetary benefits The following benefits are envisaged for the Chief Executive Officer in line with the Eni policies established for all Executives: (i) insurance coverage for death and permanent disability, for occupational injury and disease and elsewhere; (ii) supplementary pension and healthcare plan; (iii) company car. Pay mix The remuneration package for the Chief Executive Officer includes a fixed component, a short-term variable component, and a long-term variable component (deferred portion of the short-term incentive and equity-based long-term incentive) determined using internationally recognised methodologies for remuneration benchmarks. The pay mix is weighted significantly towards the variable components, with a dominant weighting attributed to the long-term component, as shown in the figure below. Employee Stock Ownership Plan 2024-2026 Based on that established in the Information Document for the Employee Stock Ownership Plan 2024-2026, available on the Company’s website, the Chief Executive Officer and General Manager participate in the Plan, albeit with a purely symbolic annual grant of 1 Eni share. Payments due in the event of termination of office or employment25 SEVERANCE PACKAGE For the position of Chief Executive Officer: an indemnity in the event of early termination or nonrenewal of the office, as well as resignation justified by a reduction of delegated powers, set at two years of fixed remuneration for the position, as already provided for in the 2020-2023 term, in line with Recommendation 2009/385/EC. For the position of General Manager: indemnity in the event of the consensual termination of the management relationship, set at two years of fixed remuneration plus short-term incentive, below the maximum protections of the appropriate national collective bargaining agreement providing for up to CHART 13 – PAY MIX CEO 30% 40% 28% 53% 30% 19% Target Maximum Pay mix with a dominant weighting attributed to the variable long-term component

three years of total actual remuneration, including fixed remuneration, short- and long-term variable incentives, and benefits26. Also with reference to Recommendation no. 27, letter f) of the Governance Code, these indemnities cannot be paid in the event of termination and/or dismissal with just cause or resignation of the interested party not justified by a substantial reduction in powers, as well as in the circumstances set out in Art. 2122 of the Italian Civil Code. NON-COMPETE AGREEMENT In relation to the continued employment relationship, the non-compete agreement already activated after the Board of Directors exercised its option right on March 14, 2019, will be maintained. The obligations under the Agreement establish a period of efficacy of 18 months with non-competition constraints for the Oil & Gas sector applying to 19 countries, supplemented with respect to companies operating in the circular economy sector. The remuneration for the Agreement, defined in relation to the obligations, envisages a fixed component of €1,800,000, plus a variable component, to be determined as a function of the average results for the STI Plan in the previous three years, between €500,000 (target performance) and €1,000,000 (maximum performance). (26) In cases of termination not due to just cause, CCNL protections call for up to a maximum of 36 months of total remuneration (fixed remuneration, variable short and long-term incentives, benefits), including that due by way of notice indemnity, consistent with national regulations (article 2121, Civil Code). Managers with Strategic Responsibilities For General Managers and other Managers with Strategic Responsibilities, the 2024 Remuneration Policy is unchanged on that for the previous term, maintaining remuneration plans that are strictly in line with those of the Chief Executive Officer, to better guide and align managerial action with the objectives set out in the Company’s Strategic Plan, and with the provisions and protections laid down by national collective bargaining agreement for executives. In particular, the Short-Term Variable Incentive Plan with deferral and Equity-based Long-Term Incentive Plan - intended for the Chief Executive Officer apply. Fixed remuneration Fixed remuneration is determined based on the role and responsibilities assigned considering a prudent positioning with respect to the median benchmarks of national and international executive markets for roles of a similar level of responsibility and managerial complexity. Remuneration may be updated, during the annual salary review involving for all managers, according to selective criteria that envisage increases to the fixed/one-off remuneration for those in positions that have seen a significant increase responsibility or scope, and to address retention risk and reward excellent performance. In addition, in their capacity as Eni officers, Managers with Strategic Responsibilities are entitled to receive allowances due for travel in Italy and abroad, in line with applicable provisions of the Italian national collective bargaining agreement for executives and supplementary Company agreements. Variable Incentive Plans SHORT-TERM VARIABLE INCENTIVE PLAN WITH DEFERRAL Managers with Strategic Responsibilities participate in the Short-Term Incentive Plan with deferral, already described for the Chief Executive Officer. The related individual targets are consistent with those assigned to the Chief Executive Officer in the context of the same policy clusters, consistent with the responsibilities of the role and the provisions of the Company’s Strategic Plan. Incentive Plans closely consistent with those provided for the CEO/GM Fixed remuneration based on roles and responsibilities

For Managers with Strategic Responsibilities, the target incentive levels for the Short-Term Variable Incentive Plan differ depending on the role’s level of responsibilities and complexity up to 100% of fixed remuneration, with a maximum incentive level payable for the annual and deferred portions of 98% and 121% of fixed remuneration, respectively. LONG-TERM VARIABLE INCENTIVE PLAN Managers with Strategic Responsibilities participate in the 2023-2025 Long-Term Incentive Plan. The Plan is directed at managers who are critical for the business and envisages three annual awards, starting in 2023, with the same performance conditions and characteristics as those described above for the Chief Executive Officer. For Managers with Strategic Responsibilities, the value of the shares to be awarded each year differs depending on the level of their role and is limited to a maximum of 75% of fixed remuneration, with the maximum grant corresponding to 135% of fixed remuneration, calculated with reference to the price at which the shares were awarded. RISK MITIGATION CLAUSES For General Managers and other Managers with Strategic Responsibilities, the same malus/ clawback and share lock-up clauses envisaged for the Chief Executive Officer and the General Manager apply. Non-monetary benefits The following benefits are envisaged for Managers with Strategic Responsibilities, as defined in national collective bargaining agreements and supplemental company agreements for all Eni executives: (i) life insurance and insurance against permanent disability due to workplace or other injury or illness; (ii) supplementary pension plan (FOPDIRE fund) and supplementary health plan (FISDE fund); (iii) company car for business and personal use and possible housing for operational and mobility requirements. Pay mix The remuneration package for Managers with Strategic Responsibilities, as for the Chief Executive Officer, includes a fixed component, a short-term variable component, and a longterm variable component (deferred portion of the short-term incentive and equity-based longterm incentive) determined using internationally recognised methodologies for remuneration benchmarks. As shown by the chart, the pay mix maintains a significant focus on the variable components, with prevalence of the long-term component, in line with the practice of the benchmark markets.

Employee Stock Ownership Plan 2024-2026 (27) Total actual remuneration includes fixed remuneration, short and long-term variable incentives and benefits. Based on that established in the Information Document for the Employee Stock Ownership Plan 2024- 2026, available on the Company’s website, Managers with Strategic Responsibilities participate in the Plan, albeit with a purely symbolic annual grant of 1 Eni share. Payments due in the event of consensual termination of employment Managers with Strategic Responsibilities, like all Eni executives, are entitled to severance benefits for employment termination established by law and in the CCNL for industrial Managers together with any termination indemnities agreed on an individual basis, in accordance with the criteria established by Eni for cases of retirement incentives, taking into account the position held and performance, within the limits of protections envisaged by the same collective bargaining agreement and consistent with application criteria of the Italian Corporate Governance Code (Recommendation no. 27, letter f). These protections envisage, in cases of termination without just cause, up to a maximum of three years of total actual remuneration, calculated in line with the provisions of Art. 2121 of the Civil Code27 and of the CCNL for industrial executives (Art. 19). For cases of termination that present high competitive and litigation risks relating to the nature of the position, agreements may contain additional non-compete clauses, with duration up to one year and payments defined in relation to remuneration level, scope, duration and effectiveness of the agreement. The consensual termination of the employment relationship entails, for the beneficiaries of Long-Term Incentive Plans, the pro-rata payment of the incentives in proportion to the vesting period that has elapsed, taking into account. Consistent with national regulations and the CCNL for industrial

Section II Compensation and other information This Section will be subject to a non-binding vote during the Shareholders’ Meeting of May 15, 2024, according to the provisions of the applicable legislation. INTRODUCTION In accordance with the Consob Issuers Regulation, Section II reports the remuneration for 2023 on an accrual basis, showing fixed remuneration accrued in 2023 and short and long-term variable incentives accrued with respect to the final performance in 2023 and payable/grantable in 2024. As regards the 2024 Short-Term Incentive accrued in 2023 for Chief Operating Officers and other Managers with Strategic Responsibilities, since individual performance results are unavailable at the date of approval of this Report, the Report shows the value of incentives envisaged by the Policy at the level of individual target performance. As regards the Long-Term Equity Incentive awarded in 2021 with accrual period 2021-2023, since the final results of the parameter NPV of Proven Reserves of hydrocarbons are available only after the publication of the financial statements of the companies making up the Peer Group, the Report shows the value of incentives based on an estimate of the final multiplier calculated on the basis of the results already recorded and an estimate of the 2023 result of the stated parameter NPV of Proven Reserves at target level. The incentives that will actually be paid/granted in 2024, both relating to the Short-Term Plan and the Equity-Based Long-Term Incentive Plan, will be disclosed in the Remuneration Report to be published in 2025. Finally, Section II of this Report provides additional information on the implementation of the remuneration policies for 2022, concerning the values of incentives actually paid/granted in 2023 and for which, at the date of approval of the 2023 Report, the data necessary for verifying the performance results were not available. Disclosure on remuneration changes For the Chairman and the Non-Executive Directors and Statutory Auditors, there were no changes in remuneration in 2023 compared to 2022, their remuneration having remained unchanged. For the Chief Executive Officer and General Manager, fixed remuneration for 2023 remained unchanged, while overall 2023 remuneration, including incentives paid on verified performance, showed a change of 32% over 2022, mainly reflecting the change in the Equity-Based Long-Term Incentive Plan granted in 2023 compared to the previous year, in relation to the increase in the Eni share price at the grant with respect to the time of awarding (€15.27 vs. €8.21).

This figure is 5.2% if newly acquired companies are not considered. The change is in part due to initiatives implemented by the company to protect the purchasing power of employees against the high inflation seen during the period. The change in 2022-2021 was +4.1%, and in 2021-2020 was +0.9%. In 2023 Eni achieved excellent economic and financial results, supported by industrial management in which asset integrity played a key role, guaranteeing the sustainability of production targets, as did financial discipline. Pro forma adjusted operating profit (including the Eni portion of the contribution from our affiliates) was around €18 billion; adjusted net profit was €8.3 billion. Cash flow generation was robust with €16.5 billion in operating cash flow before the change in working capital, which net of organic capex of €9.2 billion shows an organic FCF of €7.3 billion, much higher than the still excellent cash return seen by the shareholders during the year of €4.8 billion, in the form of €3 billion in dividends and the execution of a buy-back plan with an outlay of €1.8 billion. These results allowed the Group to achieve a solid asset structure, with 20% leverage. IMPLEMENTATION OF THE 2023 REMUNERATION POLICIES The implementation of the Remuneration Policy covering 2023 for Directors, Chief Operating Officers and other Managers with Strategic Responsibilities was verified by the Remuneration Committee during the periodic assessment provided for in the Corporate Governance Code and was found to be compliant with the Remuneration Policy approved by the Shareholders’ Meeting on May 10, 2023, kept unchanged with respect to the previous term, based on decisions taken by the Board of Directors on June 1, 2023. Verification of 2023 performance for the purpose of the accrual of incentives payable and/or grantable in 2024 This section covers the verification of results for 2023, as approved by the Board of Directors on March 13, 2024 for the purpose of incentives payable/grantable and/or awardable in 2024 to the Chief Executive Officer and General Manager, Chief Operating Officers and other Managers with Strategic Responsibilities.

Deferred Short-Term Plan (STI Plan) 2024 VERIFICATION OF OBJECTIVES 2023 Verification of the objectives assigned to the Chief Executive Officer and General Manager for 2023 was approved by the Board, following verification and a proposal from the Remuneration Committee, at its meeting on March 13, 2024, with a performance score of 140 points calculated. The table below shows the weightings and performance achieved for each objective. Verification of objectives was conducted using the gap-analysis methodology approved by the Remuneration Committee, which calls for neutralisation of external factors such as the commodity price situation and exchange rates, as well as events that by their nature are not attributable to management performance, so as to ensure results can be accurately compared with the targets assigned. The following are the main results for each objective: • EBT: the result was better than the target, in particular with reference to the record result for GGP due to optimisation of the natural gas and LNG portfolio and renegotiations of contracts, UPS cost efficiency, as well as improved performance for GTR&M and Plenitude; • Free Cash Flow: an improvement compared to the target as a consequence of excellent economic results, as well as widespread optimisation; • Hydrocarbon Production: higher than the target thanks to higher contributions coming from Libya, Algeria, Indonesia and Venezuela; • Incremental Installed Renewable Capacity: an improvement on the target, achieved through developing the project pipeline and selective portfolio operations; • Severity Incident Rate (SIR): an improvement with respect to the target, confirming Eni’s commitment to utilising new tools intended to disseminate a culture of safety at all company levels, affecting worker behaviour and more closely monitoring the in the field activities of our partners; • Net emissions upstream Scope 1 and 2 equity: the result benefited from actions to optimise operating management and make it more efficient; • ROACE: this performance was achieved by improving economic results; • Debt/EBITDA: this result is the consequence of better economic and financial results.
