4 Eni Report on remuneration policy and remuneration paid 2022 Letter from the Chairwoman of the Remuneration Committee Dear Shareholders, In 2021 Eni operated in a context still strongly affected by the pandemic, which continued to in- fluence our way of living and working, in a still volatile scenario which is now further aggravated by the breaking out of the most serious war on the European continent since the end of WWII. Therefore, our utmost attention continued to be concentrated above all on the protection of our people and the communities in which we work, through the consolidation of actions already implemented in 2020. Our timely reaction to the pandemic allowed Eni to significantly reduce costs and therefore to buffer the effects of the crisis. This translated into a 2021 performance allowing strong cash generation to cover dividends and buy-backs and reduce the debt ratio back to pre-crisis levels while, at the same time, strengthening our energy transition plan. Thanks to the effective mea- sures taken against the crisis, Eni did not have to make any redundancies or resort to subsidies. Like any crisis, the pandemic has therefore played as a further, strong lever in favour of change and acceleration of the actions already defined by our corporate mission and strategy: to ensure clean energy for all with the clear objective of carbon neutrality by 2050. In the context of war, violence and deep instability shaking our continent today, also strongly affecting the energy sector, Eni continues to show its capacity of reaction, resilience and commitment to its mission and strategy. The process that will lead to the achievement of this historic objective, structured in intermedi- ate and final goals, will be based on the pillars of decarbonisation, progressive development of renewable sources and creation of new businesses based on the paradigm of circular economy. Eni’s Remuneration Policy largely contributes to this process through both its incentive system and the weight given to decarbonisation and sustainability metrics, further refined in 2021. Shareholder engagement In carrying out the activities included in its annual program, the Committee was aware of the extraordinary nature of the conditions associated with the crisis triggered by COVID, which were evidently also reflected in the advice expressed by shareholders in 2021. Therefore, the Commit- tee thoroughly examined the rationale for the shareholders’ vote, organising a structured cycle of meetings with institutional investors and the leading proxy advisors. On these occasions, investors illustrated the reasons for their vote on the implementation of re- muneration policies for the year 2020, explaining that the deferral measures of a significant part of the variable remuneration, implemented both in 2020 and 2021, were not deemed sufficient, considering the revision of targets undertaken in light of the pandemic. They therefore hoped for voluntary reduction of wages, or the exercise of discretion in defining the final pay-outs of the incentive systems. The outcome of the meetings confirmed a general appreciation of the aims, overall structure and specific articulations of Eni’s Policy, with regard in particular to the balance between the economic-financial indicators and those aimed at measuring energy transition. The Committee greatly appreciated the feedback received, drawing useful information on the need to maintain an effective dialogue with investors, especially in exceptional circumstances, in order to know their orientations and receive feedback on choices made. In drafting the 2022 Report and more specifically the second section of the document, the aim of further improving the description of the methodology and assessments carried out when verifying the performance was also shared, in compliance with the mandate of the Committee. Methodologies applied, assessments carried out and the proposals presented to the Board will also be thoroughly illustrated during the meetings scheduled for the spring of this year, in an- ticipation of the shareholders’ meeting, which will be called to express a non-binding vote only on the second section of the document, in consideration of the three-year duration of the Policy approved in 2020. Nathalie Tocci Chairwoman of the Remuneration

5 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex The importance of a direct and constructive dialogue with investors is finally pointed out by the explicit inclusion, among the Committee’s tasks, of a specific item on the examination and monitoring of the results of engagement activities carried out in support of Eni remuneration policy, within the terms provided for in the policy approved by the Board, in line with the recommendations of the new Corporate Governance Code. Results in 2021 Building on actions taken in 2020, we achieved excellent results in 2021 and accelerated our energy transition strategy. Strong cash generation provided €7.6 bln of organic free cash flow which supported the acceleration of the growth of green businesses and ensured a remuneration to the shareholders in line with pre-pandemic levels while reducing the debt ratio at 20%, compared with 31% last year. During 2021, we laid solid foundations for a further transformation of our portfolio with the announcement of the listing of Plenitude, which includes renewables, customers and electric mobility, and the IPO of Vår Energi on the Norwegian stock exchange, as well as the creation of a strategic vehicle with BP for the joint development of activities in Angola. In terms of work safety, we recorded the best performance in the last 5 years, based on an indicator that also considers the severity of any accident (SIR), confirming Eni’s commitment to raising awareness and disseminating a culture of safety. In a nutshell, in 2021 we achieved very important results, confirming the effectiveness of the strategy launched at the very beginning of the pandemic. Looking forward: Remuneration policy for the new term The Committee members are aware that the three-year Policy implemented over these years, while proving robust and bal- anced, may require updates to reflect the evolution of strategic guidelines, practices and the reference context, as well as indications coming from the market and investors, with a view to presenting a new proposal at the Shareholders’ Meeting to be held in 2023. An item we expect to maintain relates to the three-year duration of the Policy, which allows its natural alignment with the term of the Board and helps the consolidation of proposed solutions over time, allowing to test their validity over a sufficient period of time, and to foster the expectation of their being stable and resilient even in situations of crisis and uncertainty, as we have had the opportunity to experience over the last two years. The Committee will also assess the features and performance parameters of the long-term incentive plan that must be adopted upon expiry of the current plan, the last award of which will be approved in October, in light of the recent recom- mendations of the Corporate Governance Code, and the evolution of the Company’s strategic priorities, with the aim of continuing to promote the creation of sustainable value in the long-term. Our commitment to consolidate and further strengthen the position of excellence achieved on ESG issues, from workplace safety to the challenge of decarbonisation, up to a growing enhancement of Diversity & Inclusion issues, will remain at the centre of our work. Conclusion Dear Shareholders, the Report that, on behalf of the whole Committee, I am pleased to submit for your endorsement, illus- trates the activities and initiatives carried out in 2021 by the Committee; its second section will be subject to a non-binding vote during the Shareholders’ Meeting of May 11, 2022. Trusting in your renewed support and trust, we remain open and available for discussion, confident of our common com- mitment to building the sustainable success of society Nathalie Tocci Chairwoman of the Remuneration Committee March 9, 2022

6 Eni Report on remuneration policy and remuneration paid 2022 Foreword This Report, as approved on March 17, 2022 by the Board of Directors, acting on the recom- mendation of the Remuneration Committee, in accordance with applicable legal and regulatory requirements1:  reports, in the first section, the Policy adopted by Eni SpA (hereafter “Eni” or the “Company”) for the remuneration of Directors and Managers with strategic responsibilities2, for the whole 2020-2023 term, following its approval by the Shareholders’ Meeting held on May 13, 2020, with over 95% of favourable votes. The Policy has effect over a period of three financial years, from the date of the meeting on May 13, 2020 to the date of the Shareholders’ Meeting to be called to approve the financial statements at December 31, 2022. The first section also describes the general aims pursued, the bodies involved, and the procedures used to adopt and implement the Policy. Therefore, this Report reports the content of the first section of the 2020 Report, with some limited adjustments to describe the Remuneration Committee activities in 2021. Since no changes are expected to the Remuneration Policy for the 2020-2023 term, the first section of the Report is not subject to the vote of the 2022 Shareholders’ Meeting. The gen- eral principles and guidelines outlined in the first section of this Report also apply to the re- muneration policies of companies directly or indirectly controlled by Eni3, with the exception of listed subsidiaries (including jointly controlled ones), directly required to apply the legislation;  illustrates, in the second section, the implementation of the 2021 Policy with information on the assessment of the results, as well as, the remuneration paid and shareholdings held in 2021 by Eni Directors, Statutory Auditors, Chief Executive Officer and General Manager, Chief Operating Officers4, as well as, in aggregate form, other Managers with strategic responsibilities. Finally, this Section explains how the terms of the 2020-2022 Long-Term Monetary Incentive Plan were applied in 2021, in accordance with applicable regulation5.

8 Eni Report on remuneration policy and remuneration paid 2022 Executive Summary The Eni Remuneration Policy is approved by the Board of Directors, following a proposal by the Remuneration Committee, which is entirely made up of non-executive, independent Directors. It is defined in accordance with the corporate governance model adopted by the Company as well as with the recommendations of the Italian Corporate Governance Code. Following the approval by the Shareholders’ Meeting of May 13, 2020, the Remuneration Policy presented in the first section of this Report provides the Remuneration Policy Guidelines for Di- rectors, Statutory Auditors and other Managers with strategic responsibilities for the 2020-2023 financial years, i.e. coinciding with the term of Eni’s corporate bodies. On March 18, 2020, the Board of Directors approved the aforementioned Policy Guidelines, act- ing on a proposal of the Remuneration Committee, following a preliminary analysis of the rel- evant regulatory framework, as regards in particular new requirements resulting from the trans- position of the SRD II Directive, market practices in Italy and abroad as well as remuneration benchmark analysis carried out with the support of international advisors. The 2020-2023 Policy Guidelines were also defined taking into due account the views expressed by the shareholders on the 2019 Policy (which received a favourable vote from 96.78% of the participants), thus retaining the same structure and potential maximum remuneration levels for the Chairwoman and CEO, as well as for non-executive Directors in relation to their participation in Board Committees. Finally, the 2020-2023 Policy Guidelines also contain, in accordance with the provisions of the law transposing the SRD II, specific recommendations on the remuneration of the Chairwoman and other members of the Board of Statutory Auditors for the entire duration of their term, which were determined at the Shareholders’ Meeting on the occasion of their appointment.

10 Eni Report on remuneration policy and remuneration paid 2022 GHG emission intensity in the upstream sector Scope 1 + 2 (equity) on operated and non- operated basis: following the introduction of this parameter within the objectives of Eni’s short and long-term incentive plans, we report the trend of related results for the period 2018-2021. In particular, 2021 performance, as shown in chart 3, posted an increase mainly due to a gen- eral decrease in production and a slight increase in emissions, in particular due to emergency outages in Nigeria and Angola and the resumption of onshore activities in Libya. The effect is partially offset by the increase of production at Zohr (low-emission impact assets). CEO/GM pay ratio: below (Table 1) are 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 with reference to both fixed remuneration and total remuneration11; total Eni pay ratio in 2020 was on average higher than those published by other Peer Group companies (Apache, BP, Chevron, ConocoPhillips, Exxon Mobil, Marathon Oil, Occidental, Shell) with an average value in 2020 of approximately 103, reflecting the accrual by Eni CEO/ GM of the Long-Term Stock Incentive and the reduction or non-payment of the 2020 bonus for some Peers. TABLE 1 – CEO/GM PAY RATIO VS. MEDIAN EMPLOYEE REMUNERATION Employees in Italy 2018 2019 2020 2021 Ratio between fixed remuneration of the CEO/GM and median fixed remuneration of employees 37 37 37 36 Ratio between total remuneration of the CEO/GM and median total remuneration of employees 115 108 97 138 All employees Ratio between fixed remuneration of the CEO/GM and median fixed remuneration of employees 38 37 36 36 Ratio between total remuneration of the CEO/GM and median total remuneration of employees 118 110 97 141 Gender pay ratio: below (Table 2) are the gender pay ratio data for fixed and total remuneration, which show a substantial alignment between the salaries of the female and male populations for the Italian and global population, with differences between the years statistically not significant. In calculating the pay ratio, Eni uses a method that neutralizes the effects deriving from differences in the level of role and seniority according to the United Nations principle of “equal pay for equal work”. However, the alignment is confirmed also when determining the pay ratio without neutralisation in the level of role (“raw”); in particular, raw pay ratio came to 100% for fixed remuneration and 97% for total remuneration in 2021. (11) Total remuneration includes monetary remuneration and benefits.

Minimum wages: Eni has policy remuneration standards well above the legal/contractual mini- mums (Table 3), as well as the 1st decile of the local remuneration market, for all Countries in which it operates12. We annually check our positioning in terms of remuneration, adopting any necessary corrective actions. Table 3 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. (12) The 1st decile represents the level below which ranks 10% of remuneration.

12 Eni Report on remuneration policy and remuneration paid 2022 Link between business model for sustainable development and long-term remuneration Strategy, sustainable development and remuneration Eni’s business model is focused on creating value for its stakeholders through a strong pres- ence 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 giv- ing access to energy resources for all in an efficient and sustainable way. The 2020-2022 Long-Term Equity based Incentive Plan supports such model and the guidelines of the Strategic Plan by providing a specific goal on environmental sustainability and energy transition (with an overall weight of 35%), made up of targets related to decarbonization, energy transition and circular economy.

20 Eni Report on remuneration policy and remuneration paid 2022 Compliance of Policy with provisions of law and By-laws Section I – Remuneration Policy for the 2020-2023 term This Section is not subject to the vote of the 2022 Shareholders’ Meeting since the Remuneration Policy for the 2020-2023 term has already been approved by the Shareholders in their Meeting of May 13, 2020 and no changes are expected. Corporate governance BODIES AND PARTIES INVOLVED The Policy governing the remuneration of members of the Eni Board of Directors, Board of Statu- tory 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 Chairwoman and other mem- bers 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, within the Remuneration Policy described in the first section of this Report, the recommendations and general criteria for remunerating members of the Board of Statutory Auditors and Managers with strategic responsibilities;  defining the Company’s targets and approving the Company’s performance thereby determin- ing the variable remuneration of eligible Directors with delegated powers;  subject to a proposal of the Chairwoman in agreement with the Chief Executive Officer, defin- ing 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. In line with the recommendations of the Italian Corporate Governance Code, the Board of Direc- tors is supported, by a Committee of independent Non-Executive Directors (the Remuneration Committee) which makes proposals and provides advice on remuneration issues (including the approval and revision of the Policy to be submitted to the Shareholders’ Meeting). 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. To this end, the Remuneration Policy is outlined in the first section of the Remuneration Re- port which will be published no later than twenty-one days before the date of the Shareholders’ Meeting at which shareholders are invited to approve the financial statements (Art.123-ter, first paragraph, of Italian Legislative Decree 58/98 - Consolidated Law on Financial Intermediation). The Board of Directors ensures that the remuneration paid and accrued is consistent with the (13) For more information regarding the Eni corporate governance system, please refer to the “Corporate Governance Report” published in the “Corporate Governance” section of the Company website.

21 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex principles and criteria defined in the Policy, in light of the results achieved and other circum- stances relevant to its implementation (Principle XVII of the Corporate 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 Op- erating Officers and, in aggregate, Managers with strategic responsibilities. ENGAGEMENT ON REMUNERATION POLICY At Eni, we develop interaction with our shareholders and institutional investors regarding remu- neration 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 transpos- ing the guidelines contained in the SRD II. In this context, the analysis of the shareholders’ vote carried out by Eni since 2012 plays an important role, since it draws particular attention on the voting trends of minority shareholders and the evolution of their positions over time. In line with the purposes and methods set out in the “Policy for managing dialogue with inves- tors”, approved by the Board of Directors, dialogue with the institutional investors and the lead- ing proxy advisors on remuneration issues is, in particular, ensured with an articulated engage- ment plan implemented on an annual basis in support of the Policy proposals to be submitted for examination to the Shareholders’ Meeting. The Chairwoman of the Committee, applying an established practice in the last years, attends the meetings in order to underscore the importance of direct communication with the market in relation to issues relevant to the Committee. The Committee is kept constantly informed of activities aimed at defining and implementing the annual engagement plan. The outcome of meetings is monitored, and the feedback received is analysed and assessed in order to provide clarification and verify the resolution of any poten- tially critical issues. The Committee provides the Board of Directors with adequate information on developments in the engagement on remuneration issues, also in the framework of periodic information on relevant issues addressed during its meetings, with the support of the competent Investor Rela- tions function. The Committee also reports on its procedures at the annual Shareholders’ Meeting by way of the Committee Chairwoman or other duly designated member. This activity is performed through a number of tools and communication channels, including: the organisation of periodic meetings and conference calls; the Shareholders’ Meeting as a con- cluding assessment of past interactions; and the provision of comprehensive, detailed informa- tion on our website. Full information regarding remuneration of Directors and management is regularly updated and made available under “Remuneration”14 in the “Company/Governance” section of the Company website.

24 Eni Report on remuneration policy and remuneration paid 2022 Governance In the first part of 2021, in implementation of the recommendations of the Corporate Governance Code, the Committee conducted its periodic the adequacy, overall consistency and actual implementation of the Remuneration Policy as implemented in 2020, for Directors and Managers with strategic responsibilities. The Committee then analysed, over several sessions, Eni’s 2021 Remuneration Report prepared pursuant to Art. 123-ter of Italian Legislative Decree 58/98 and Art. 84-quater of Consob Issuers Regulation, for the purpose of subsequent approval by the Board and presentation to the Shareholders Meeting of May 13, 2021, invited to vote only on a non-binding resolution on the second sec- tion, considering that the Policy, in consideration of the three-year duration of the policy approved in 2020. The Committee also examined the proposals for updating its own Rules to take into account the needs of adaptation to the new Code of Corporate Governance and for consistency with the Rules of other Board Committees. In the second part of the year the Committee reviewed the analysis of the results of the 2021 Shareholders’ Meeting, starting in June, as compared with the results of the leading Italian and European corporations and with those of the companies within the relevant Peer Group. The Committee also periodically monitored developments in the legislative framework and market stan- dards concerning the reporting of remuneration-related information, with a specific focus on activities carried out in 2020 and/or planned for 2021 by the leading Italian and international companies in response to the COVID-19 pandemic. Compensation With regard to issues concerning the implementation of remuneration policies, in 2021 the Committee performed the follow- ing activities:  verification of the Company’s 2020 results for the purpose of implementing the Short- and Long-Term Variable Incentive Plans, using a predetermined gap analysis method approved by the Committee in order to neutralise the positive or nega- tive impact of exogenous factors and enable the objective assessment of the performance achieved;  definition of 2021 performance targets relevant to the variable incentive plans;  definition of proposals for the implementation of the Short-Term Incentive Plan with Deferral for the Chief Executive Officer and General Manager;  exam, in collaboration with the Nomination Committee, of gender parity and pay gap issues in Eni;  finalising the implementation proposal (2021 award) of the 2020-2022 Long-Term Share Incentive Plan for the Chief Execu- tive Officer and General Manager and key management personnel, and preparation of related guidelines. Engagement As part of its ongoing monitoring of the positions of institutional investors and leading proxy advisors on remuneration issues, during 2021, the Committee performed the following activities:  monitoring of the implementation of the engagement plan and review of the outcome of the meetings conducted with main institutional investors and proxy advisors also with a view to the Shareholders’ Meeting vote on the second section of the Remuneration report; these meetings were also attended by the Chairwoman of the Committee, underscoring the impor- tance the Committee attributes to shareholder dialogue;  examination of voting recommendations issued by leading proxy advisors and, in response to some remarks, launch of a reaching out effort aimed to a wide community of investors to receive and analyse their feedback and provide further infor- mation and clarifications, where required;  examination of voting projections, which were performed with the support of a leading consulting firm. The Committee also approved the annual plan of engagement with institutional investors and proxy advisors in view of the 2022 Shareholders’ Meeting. The plan confirms the practise of holding two rounds of meetings, in autumn and spring. As part of the implementation of the plan, a first round of meetings with leading proxy advisors and institutional investors already took place in November and December, with a view to exploring their positions and voting policies in 2022 and gather further feedback on the rationale for the 2021 vote. During the meetings, the Committee examined more thoroughly the reasons for the limited support expressed by the Shareholders’ Meeting, reflecting in particular the failure to implement measures such as the voluntary reduction of remuneration, considering the revision of targets undertaken in light of the pandemic, in place of the deferral measures of a significant part of the variable remuneration, implemented for both 2020 and 2021, as more comprehensively explained in the Introduction to Section II of this Report.

25 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex Governance In the first part of 2021, in implementation of the recommendations of the Corporate Governance Code, the Committee conducted its periodic the adequacy, overall consistency and actual implementation of the Remuneration Policy as implemented in 2020, for Directors and Managers with strategic responsibilities. The Committee then analysed, over several sessions, Eni’s 2021 Remuneration Report prepared pursuant to Art. 123-ter of Italian Legislative Decree 58/98 and Art. 84-quater of Consob Issuers Regulation, for the purpose of subsequent approval by the Board and presentation to the Shareholders Meeting of May 13, 2021, invited to vote only on a non-binding resolution on the second sec- tion, considering that the Policy, in consideration of the three-year duration of the policy approved in 2020. The Committee also examined the proposals for updating its own Rules to take into account the needs of adaptation to the new Code of Corporate Governance and for consistency with the Rules of other Board Committees. In the second part of the year the Committee reviewed the analysis of the results of the 2021 Shareholders’ Meeting, starting in June, as compared with the results of the leading Italian and European corporations and with those of the companies within the relevant Peer Group. The Committee also periodically monitored developments in the legislative framework and market stan- dards concerning the reporting of remuneration-related information, with a specific focus on activities carried out in 2020 and/or planned for 2021 by the leading Italian and international companies in response to the COVID-19 pandemic. Compensation With regard to issues concerning the implementation of remuneration policies, in 2021 the Committee performed the follow- ing activities:  verification of the Company’s 2020 results for the purpose of implementing the Short- and Long-Term Variable Incentive Plans, using a predetermined gap analysis method approved by the Committee in order to neutralise the positive or nega- tive impact of exogenous factors and enable the objective assessment of the performance achieved;  definition of 2021 performance targets relevant to the variable incentive plans;  definition of proposals for the implementation of the Short-Term Incentive Plan with Deferral for the Chief Executive Officer and General Manager;  exam, in collaboration with the Nomination Committee, of gender parity and pay gap issues in Eni;  finalising the implementation proposal (2021 award) of the 2020-2022 Long-Term Share Incentive Plan for the Chief Execu- tive Officer and General Manager and key management personnel, and preparation of related guidelines. Engagement As part of its ongoing monitoring of the positions of institutional investors and leading proxy advisors on remuneration issues, during 2021, the Committee performed the following activities:  monitoring of the implementation of the engagement plan and review of the outcome of the meetings conducted with main institutional investors and proxy advisors also with a view to the Shareholders’ Meeting vote on the second section of the Remuneration report; these meetings were also attended by the Chairwoman of the Committee, underscoring the impor- tance the Committee attributes to shareholder dialogue;  examination of voting recommendations issued by leading proxy advisors and, in response to some remarks, launch of a reaching out effort aimed to a wide community of investors to receive and analyse their feedback and provide further infor- mation and clarifications, where required;  examination of voting projections, which were performed with the support of a leading consulting firm. The Committee also approved the annual plan of engagement with institutional investors and proxy advisors in view of the 2022 Shareholders’ Meeting. The plan confirms the practise of holding two rounds of meetings, in autumn and spring. As part of the implementation of the plan, a first round of meetings with leading proxy advisors and institutional investors already took place in November and December, with a view to exploring their positions and voting policies in 2022 and gather further feedback on the rationale for the 2021 vote. During the meetings, the Committee examined more thoroughly the reasons for the limited support expressed by the Shareholders’ Meeting, reflecting in particular the failure to implement measures such as the voluntary reduction of remuneration, considering the revision of targets undertaken in light of the pandemic, in place of the deferral measures of a significant part of the variable remuneration, implemented for both 2020 and 2021, as more comprehensively explained in the Introduction to Section II of this Report. The Committee greatly appreciated the feedback received, drawing very useful information on the need to entertain an effective dialogue with investors, particularly in excep- tional circumstances, to have the opportunity to know their orientations and receive feedback on choices made. In drawing up the 2022 Report, the aim of more thoroughly describing, in the second Section of the Report, the methods used and the final assessment process of business performance as per the mandate of the Committee, was also expressed. During the current year, the Committee will move ahead with the implementation of the 2022 engagement plan, by organizing a second round of meetings, with the goal of ensuring a better understanding of the contents of this Report with a view to preparing the Shareholders’ Meeting scheduled for May 11, which will be called to express a non-binding vote on the second section of this Report describing the implementation of remuneration policies in 2021. 1st QUARTER JANUARY - MARCH 2nd QUARTER APRIL-JUNE 3rd QUARTER JULY-SEPTEMBER 4th QUARTER OCTOBER-DECEMBER Governance Governance Governance Governance  Definition/Evaluation of Remuneration Policy Guidelines.  Preparation of the Remuneration Report.  Presentation of the Remuneration Report to the Shareholders’ General Meeting.  Benchmark analysis of the results of the vote of the Shareholders’ Meeting on the Policy.  Monitoring of the regulatory framework and of the voting policies of leading institutional investors and proxy advisor.

26 Eni Report on remuneration policy and remuneration paid 2022 Policy consistent with recommendations of Corporate Governance Code No increase in the total remuneration levels Strengthening clawback clauses 2020-23: Guidelines main changes towards previous term 2020-2023 REMUNERATION POLICY APPROVAL PROCESS In the exercise of its powers, the Remuneration Committee in charge in the previous term defined the structure and contents of the Remuneration Policy in force, specifically at meetings held on January 20, February 19 and March 2nd, 2020, in accordance with the recommendations of the Corporate Governance Code. In taking its decisions, the Committee reviewed the appropriateness, overall consistency and effective implementation of the 2019 Policy Guidelines. The Committee also considered comparative remuneration studies prepared by independent inter- national consultants (Mercer, Willis Towers Watson and Korn Ferry-Hay Group), in the preliminary analysis for the new Remuneration Policy proposals. The studies basically confirmed the prudent positioning with respect to the benchmark panel. In preparing the Policy, it also considered changes in the regulatory framework, more specifi- cally as related to the transposition of the SRD II into Italian law. Following the engagement with leading institutional investors and proxy advisors, the Committee received a confirmation of the general appreciation of the structure and the remuneration levels already provided for by the previous Remuneration Policy. Consequently, with a view to designing the Policy Guidelines for the new three-year term starting in April 2020, the Committee proposed implementing the following guidance:  structure and structure of Eni’s remuneration policy in line with that previously in force, which provides for two variable incentive plans, a short-term plan with deferral and a long-term, share- based plan for managers with the greatest impact on Company performance. In more detail, the share-based 2020-2022 incentive plan provides for the introduction of absolute targets spe- cifically related to the decarbonisation process and the energy transition, also in response to the significant interest expressed by investors for sustainability and environmental issues. The Plan also provides for the application of pro rata payment mechanisms for the incentives for the CEO in the event of termination related to the expiry of the term of office with no reappointment;  maximum remuneration levels for top managers in line with those in force for the previous term, with no increases in fixed remuneration, which was defined by the Board on the basis of the actual delegated powers and profiles, and the skills/experience of the designated manag- ers, within the limits specified in the Guidelines presented in this Report. Furthermore, the 2020-2023 Policy foresees:  the inclusion in existing risk mitigation clauses of specific “malus” conditions, aimed at ensur- ing ex ante verification of conditions for the payment and/or award of variable incentives;  the provision, in line with the law transposing the SDR II, of specific recommendations on the remuneration of members of the Board of Statutory Auditors, as specifically determined by the shareholders who voted the composition and appointment of this Board on May 13, 2020. The 2020-2023 Eni Remuneration Policy for Directors, Auditors and other Managers with strate- gic responsibilities was approved by the Board of Directors, acting on a proposal of the Remu- neration Committee, at its meeting of March 18, 2020, and then approved by the Shareholders’ Meeting held on May 13, 2020, with 95.28% of voters. The 2020-2023 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 Remunera- tion 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.

27 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex Purpose and general principles of the Remuneration Policy PURPOSE The Eni Remuneration Policy contributes to pursuing the Company’s strategies, with the definition of incentive structures tied to the achievement of financial, business, environmental and social sustainability, energy transition goals, as well as operational and individual development objec- tives, defined with a view to the achievement of Long-Term business performance, taking account of the interests of all stakeholders. Eni’s Remuneration Policy is also consistent with the governance model adopted by the Com- pany and the recommendations of the Italian Corporate Governance Code, in particular provid- ing that the remuneration of Directors, members of the Board of Statutory Auditors, General managers and Managers with strategic responsibilities is functional to the pursuit of the sus- tainable success of the Company and reflects the need to have, retain and motivate people whit the competence and profesionalism deemed for adeguate of the role assigned in the Company (Principle XV of the Corporate Governance Code). Eni’s Remuneration Policy contributes to achieving the Company’s mission, towards:  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, with fair references based on the role and 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. GENERAL PRINCIPLES In pursuing the above, the remuneration of Directors and key executives is defined in line with the following principles and criteria: MARKET REFERENCES 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 relevant national and international comparators, also in terms of industry and company size, that were developed through benchmarking analysis carried out by international remuneration advisors (Recommendation no. 25). STRUCTURE OF EXECUTIVE REMUNERATION 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, taking due account of the risk profile of the business and of the sector of activity (Recommendation no. 27, letter a). Executive roles with the greatest influence on business performance are characterised by vari- able 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, in line with the long-term nature (18) For more information on the Code of Ethics, please refer to the Report on Corporate Governance and Ownership Struc- ture 2021, available on the Company website. (19) Policy approved by the Board of Directors on July 28, 2010. Consistency with the Company’s strategies Consistency with the governance model and recommendations of Corporate Governance Code Support to the mission and to the realization of corporate values ​ and culture Pay setting and salary-review processes anchored to relevant market benchmarks Vesting and/or incentive deferral period of at least three years

28 Eni Report on remuneration policy and remuneration paid 2022 of the business activities performed and with the associated risk profile (Recommendation no. 27, letter d). FIXED REMUNERATION The fixed component is consistent with role and/or responsibilities, as well as adequate in the event of non-payment of the variable component. VARIABLE REMUNERATION The variable component in defined within maximum limits (Recommendation no. 27, letter b) and is aimed at aligning remuneration with performance. INCENTIVE TARGETS AND SUSTAINABILITY OF RESULTS Financial and non-financial targets related to short- and long-term variable remuneration, includ- ing equity-based compensation, are defined in a manner consistent with the four-year Strategic Plan and with the expectations of shareholders and stakeholders, in order to foster a strong results-oriented focus and combine operational and financial soundness with social and envi- ronmental sustainability (Principle XV e Recommendation no. 27, letter c). Targets are defined in advance, measurable and mutually complementary in order to fully capture the priorities that underpin the Company’s overall performance. 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;  the definition of Long-Term Incentive Plans that allow Company performance to be evaluated both in absolute terms, i.e., based on the capacity to generate sustained growth in profitability, and in relative terms compared with a Peer Group, by way of a ranking against Eni’s main interna- tional competitors. SHARE-BASED COMPENSATION PLANS Share-based compensation plans are designed to ensure alignment with shareholders expectations over the medium-to-long-term, by way of: three-year vesting periods, linkage with predetrmined and measurable performance targets, the provision of a withholding period that applies to a proportion of share awards of at least one year (Recommendation no. 28)20. VERIFICATION OF RESULTS Incentive awards linked to variable remuneration are made pursuant to a detailed verification pro- cess that assesses actual performance against assigned targets, net of the effects of exogenous variables such as the commodity price scenario and exchange rate or events which by their nature can alter performance, such as factoring or portfolio extraordinary transactions. The results verifi- cation process is based on a variance analysis method approved by the Remuneration Committee. RISK MITIGATION CLAUSES The adoption, with specific rules approved by the Board of Directors, acting on a proposal of the Remuneration Committee, of mechanisms that, on conditions determined and expressly referred to in the Plan Regulations, provide for:  the restitution of the variable component of remuneration, if already paid and/or granted (clawback);  the withholding/withdrawal of the variable components of remuneration, already vested or granted (malus). (20) The 2020-2022 LTI share-based plan, provides for a three-year vesting period to which is added, for a portion of the shares, an additional holding period of one year, totalling four years. Any adjustment to the Recommendation no. 28 of the new Corporate Governance Code may be evaluated when adopting future plans. Target defined in a line with the Strategic Plan and with the expectations of shareholders and stakeholders Verification of results net of the effect of any exogenous factors Clawback Malus

29 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex These mechanisms shall apply in cases when the incentives (or the rights thereto) have vest- ed based on data that subsequently proved to be manifestly misstated (Recommendation no. 27, letter e), or in cases of wilful alteration of the same data. The same mechanisms shall apply in cases of termination for disciplinary reasons, including se- rious 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 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. NON-MONETARY BENEFITS Non-monetary benefits are determined in line with relevant market comparators, consistent with local regulation, in order to complete and enhance the overall remuneration package, taking ac- count of the roles and/or responsibilities, and allowing for relevant social security and insurance components. SEVERANCE INDEMNITIES AND NON-COMPETE AGREEMENTS To the extent that additional payments may be awarded upon termination of employment and/or term of office for executive roles, and that non-compete agreements may apply for roles at greater risk of “poaching”, these 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 for by the collective bargaining agreements, if applicable. REMUNERATION OF NON-EXECUTIVE DIRECTORS Remuneration of Non-Executive Directors is commensurate with competence, professional qualification and effort required for participation on Board Committees set up in accordance with the By-laws (Recommendation no. 29); appropriate differentiation between the remunera- tion afforded to Committee Chairmen, and that of other Committee Members, considering the different roles respectively held regarding coordination of work and relationships with Corpo- rate 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 THE MEMBERS OF THE BOARD OF STATUTORY AUDITORS Remuneration is commensurate with the role played and competence, professional qualifica- tion and effort required for participation in the meetings of the Board and Board Committees, taking account of relevant market benchmarks at the national level, appropriately differentiat- ing between the remuneration of the Chairman and that of other Auditors, considering the coordination and liaison activities performed by the Chairman with other corporate bodies and functions (Recommendation no. 30). Pension and social security benefits Severance indemnities and non-compete agreements consistent with remuneration received and results achieved No variable remuneration for Non-Executive Directors

30 Eni Report on remuneration policy and remuneration paid 2022 Remuneration Policy Guidelines 2020-2023 The Remuneration Policy Guidelines are those outlined in the 2020 Remuneration Report and approved by the Shareholders’ Meeting on May 13, 2020 for the 2020-2023 period. No changes are expected. Following the renewal of the corporate bodies, as resolved by the Shareholders’ Meeting of May 13, 2020, the Board of Directors of June 4th, and July 29, 2020, resolved, upon proposal of the Remuneration Committee, the remuneration of the Chairwoman of the Board of Directors and of the Chief Executive Officer, in accordance with the Guidelines, also taking into account the delegated powers conferred on the Chairwoman21 as well as the assignment, to the Chief Executive Officer, of the position of General Manager, as more comprehensively described in Section II of this Report. CRITERIA FOR DEFINITION OF THE POLICY This section contains the Remuneration Policy Guidelines for 2020-2023 as defined by the Board of Directors of March 18, 2020 for Directors, Statutory Auditors and Managers with stra- tegic responsibilities and approved by the Shareholders Meeting of May 13, 2020, with 95.28% of voters. As mentioned in the Foreword to this Report, the Remuneration Policy, as approved by the 2020 Shareholders’ meeting, applies for a period of three years coinciding with the duration of the new term; since no changes are expected, it is not subject to a shareholder vote in 2022. In reporting the description of the Remuneration Policy Guidelines for Directors for the 2020- 2023 term already contained in the 2020 AND 2021 Report, it is recalled that these have been defined on the basis of regulatory provisions and the advice of institutional investors and proxy advisors, taking into account the opinion expressed by the 2019 Shareholders’ Meeting (96.78% of voters), as well as the results of benchmarks studies. Therefore, the Guidelines for 2020-2023 were developed by providing a maximum potential remuneration, equal to that established for the 2017-2020 term. Detailed information on the implementation of the Guidelines in this financial year are contained in the first part of the second section of this Report, to which reference is made. CONNECTION WITH CORPORATE STATEGIES Remuneration policies support achievement of the targets set in the Company’s Strategic Plan by promoting, through a balanced use of performance indicators in the short- and long-term incentive systems, the alignment of senior management’s interests with the priority of creating sustainable value for shareholders and other stakeholders over the medium-to-long-term. The pillars of the Company’s strategy include long-term value creation, attention to the environment, safety and people, strict financial discipline, together with a strong commitment to the ongoing decarbonisation process; they guide the management activity, which is assessed:  in a short-term horizon, in relation to a comprehensive and balanced framework of comple- mentary targets, aimed at ensuring the profitability of the Company as a whole and opera- tional efficiency in traditional business sectors, the implementation of the energy transition and decarbonisation path, through the incremental installed capacity relating to renewable (21) On May 14, 2020, the Board of Directors conferred on the Chairwoman the powers for the identification and promotion, in agreement with the Chief Executive Officer, of strategic integrated projects and international agreements. The Board also confirmed her role of guarantee within the internal control system, in particular with the management of the hierarchical relationship of the Head of Internal Audit to the Board. Finally, the Chairwoman will perform her statutory representative functions, in particular, by managing the Company institutional relations in Italy, in collaboration with the Chief Executive Officer.

31 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex sources and the extension of the GHG emission intensity indicator to Scope 1 and Scope 2 equity emissions, human safety as well as financial solidity;  in the medium-to-long-term horizon, with reference to stock performance (TSR) and generat- ed value (NPV of proven reserves), assessed in relative terms with respect to peers, as well as, starting with the new share-based Incentive Plan 2020-2022, in relation to a series of results measured in absolute terms and characterized by a significant focus on the decarbonisation process, the energy transition and circular economy. MARKET BENCHMARKS AND PEER GROUP For the Chief Executive Officer, the positioning of the Company’s remuneration is assessed by comparing the median vale for similar roles within the international Oil & Gas industry, with regard to upstream activities in particular and in line with the Company’s strategy to increase its focus on this segment of the business. The median value of the remuneration of the Chief Executive Officer is also adjusted for differences in capitalisation compared with Eni. The comparator group includes 10 listed companies, which are Eni’s competitors at the inter- national level and possess comparable business characteristics, with regard to operations and geographical areas of interest, while taking account of median corporate dimensions (in terms of capitalization, reserves, output): Apache, BP, Chevron, ConocoPhillips, Equinor, Exx- onMobil, Marathon Oil, Occidental, Shell and Total. In line with this approach these companies also make up the Peer Group used for the relative comparison of Eni’s performance under the new Long-Term Share Incentive Plan. Accordingly, the selection criteria required consideration only of those companies that publish data on the NPV of proven reserves that are comparable with Eni, using the calculation method defined by the SEC. For the Chairwoman and the Non-Executive Directors, the positioning of remuneration is as- sessed by comparing similar roles in the Top Italy 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). For Managers with strategic responsibilities, the positioning of remuneration is assessed by comparing roles of the same level of managerial complexity and responsibility within indus- trial corporations in national and international markets. Comparisons of remuneration have been conducted with the help of the advisory firms Mer- cer, Willis Towers Watson, and Korn Ferry. EMPLOYEES‘ REMUNERATION AND WORKING CONDITIONS Eni places its people at the heart of its business strategy and has always positioned itself as a “caring Company”, constantly committed to caring for its people in line with the United Na- tions 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 worldwide integrated remuneration system to all its people, also consistent with the reference markets in terms of pay progression and linked to company and individual performance, in compliance with local legislation. This system, as for the Chief Ex- ecutive Officer, adopts market references made up, for each role, by the median of the sectors to which they belong, thus guaranteeing the application of fair and competitive remuneration policies 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 minimum wages found on the local market, as highlighted by the indicators represented in the Summary, which show in particular a pay ratio of the Chief Executive Officer vs. employees on average lower than those of the Peer Group.

32 Eni Report on remuneration policy and remuneration paid 2022 Eni also pays particular attention to the safety, well-being and quality of life of its people, as driv- ing 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. Officers covered by the Policy CHAIRWOMAN OF THE BOARD OF DIRECTORS The 2020-2023 Remuneration Policy Guidelines for the Chairwoman call for a total fixed remuneration of €500,000 gross, including annual remuneration for the powers granted and emoluments as approved by the Shareholders’ Meeting. The Guidelines also provides that remuneration for powers may eventually be adjusted by the new Board based on the ac- tual powers granted and professional qualifications, taking account of remuneration bench- marks and compensation approved by shareholders for the office. 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, nor do any agreements exist for indemnities in the case of resignation or early termination of office22. NON-EXECUTIVE DIRECTORS The 2020-2023 Remuneration Policy Guidelines for Non-Executive Directors and/or independent Directors provide for the maintenance of the additional annual remuneration23 provided for in the 2017-2020 term for participating on Board Committees; this can be adjusted following a change in the structure and number of Board committees and related work, taking account of remunera- tion benchmarks and the skills and qualifications required for the office:  for the Control and Risk Committees, 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 Nomination 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 agree- ments exist for indemnities in the case of resignation or early termination of office24. (22) In consideration of the referral to this Report, in the 2021 Report on Corporate Governance and Ownership Structure, 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). (23) This remuneration supplements that to be approved by the shareholders on May 13, 2020 for Directors in the amount of €80,000 gross per year in the 2020-2023 term. (24) Information provided in accordance with Article 123-bis, paragraph 1, letter i), of the Consolidated Law on Financial Intermediation, as specified under note 22 above. Fixed remuneration Remuneration for participating on Board Committees unchanged from previous term

33 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex BOARD OF STATUTORY AUDITORS New rules provide that the Remuneration Policy should also define the criteria for setting the remuneration for the Board of Statutory Auditors (pertaining to the Shareholdersʼ Meeting, pur- suant to Art. 2402 of the Italian Civil Code). Remuneration should take into account the commitment (in terms of number and average dura- tion of meetings), the know-how and qualifications required for the office, besides remuneration benchmarks in leading listed Italian companies. Given that Eni is listed in the New York Stock Exchange, the 2020-2023 Remuneration Policy Guidelines suggest to consider an increase in the total remuneration amount for the 2020-2023 term, taking into account the activities carried out within the Board of Statutory Auditors and ad- ditional tasks to be performed in the capacity as Audit Committee pursuant to SEC regulations. CHIEF EXECUTIVE OFFICER AND GENERAL MANAGER The 2020-2023 Remuneration Policy Guidelines take the maximum remuneration level provided for in the 2017-2020 term as the maximum potential overall remuneration, allowing for adjust- ments reflecting strategic challenges and the mix of skills/experience of the designated person, taking into account remuneration benchmarks. FIXED REMUNERATION Fixed Remuneration (FR) for the 2020-2023 term cannot exceed €1,600,000; this maximum level can be decreased in the event of changes of current offices, powers and employment relation- ships, and also based on the qualifications of the designated person. This remuneration encom- passes any emoluments due for participation in the meetings of the boards of directors of other Eni subsidiaries and/or shareholdings. Should the CEO be given the role of General Manager, with the related management relationship, the CEO will also be entitled to receive an allowance for travel, in Italy and abroad, in line with the applicable provisions under the relevant national collective bargaining agreement for senior managers of industrial companies and with supple- mentary company-level agreements. VARIABLE REMUNERATION: SHORT-TERM INCENTIVES WITH DEFERRAL The guidelines for the new term provide for the maintenance of Short-Term Incentive Plan with deferral, as approved by the shareholders on April 13, 2017 within the scope of the Remunera- tion Policy Guidelines for the 2017-2020 term. Performance conditions The Short-Term Incentive with deferral is tied to achieving the annual targets set by the Board. The 2022 targets approved by the Board on March 17, 2022 for the 2023 short-term variable incentive system with deferral call for maintenance of a structure that is focused on essential milestones in line with the Strategic Plan and balanced in respect of the interests of the vari- ous stakeholders, with particular respect to the issues of energy transition and decarbonisation, through the adoption of performance indicators strictly connected to the corporate strategy and aimed at measuring the achievement of annual objectives with a view to medium-long term sustainability. The value of each indicator is in line with the budgeted figure. The structure and weight of the various targets are shown in the table 7. Maximum fixed remuneration unchanged from the previous term Adjustment of the energy transition and decarbonisation indicators

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 balance the development of the upstream business with the development objectives of renewable energy connected to the strategy of decarbonising operations and products;  the Upstream GHG emission intensity indicator (tCO2 eq./kboe) 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 car- bon footprint associated with its activities, which also involves the gradual reduction of the emission intensity of Scope 1 and Scope 2 upstream emissions, considering for this purpose both the production operated and that not operated (equity);  the indicator Severity Incident Rate (SIR) reflect Eni’s HSE priorities and the central im- portance 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 an 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 indicators ROACE and debt-to-EBITDA measure the Company’s financial discipline and the quality of our financial structure and earnings, which translates into a careful selection of invest- ments, 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. Achievement of the targets is assessed net of any variable, exogenous effects (e.g., Oil & Gas prices or euro/dollar exchange rates) and in application of a predetermined method of gap anal- ysis as 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.

35 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex ing the need to promote business development initiatives, it is also envisaged that a multiplier of 1.1 may be applied to the overall performance score to reflect portfolio development operations not foreseen in the budget, if the Board of Directors, at the time of their approval, recognizes them as transactions of particular relevance for the purposes of implementing the strategic guidelines of the 2020-2023 Plan and the Remuneration Committee considers them relevant for the purposes of annual performance. In any case, the maximum score of the performance scale cannot exceed 150 points. 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 perfor- mance level, which is set to 150% of total fixed remuneration for the Chief Executive Officer, and M is the multiplier related to overall performance, as shown in the chart below. The total incentive is divided in: 1) an Annual incentive (Iyear) equal to 65% of the total incentive, paid in the year following the year in which the performance was attained. Iyear = TI x 65% The levels of the fraction of the incentive payable during the year, depending on the performance levels achieved, are shown in the table below25. TABLE 8 – LEVELS OF ANNUAL PAYABLE INCENTIVE Annual performance <85 85 threshold 100 target 150 max Annual incentive (in % of Fixed Rem.) 0% 83% 98% 146% 2) a Deferred incentive (ID) equal to 35% of the total incentive: ID = TI x 35% subject to further performance conditions during a three-year vesting period, as shown in the chart below payable in the year after the period. (25) 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%) Annual incentive payable in the year 85% 100% 150% 85 70 100 150 Annual Performance Budget CHART 11 – TOTAL INCENTIVE MULTIPLIER Annual Multiplier Deferred incentive subject to further performance conditions during a three-year vesting period

36 Eni Report on remuneration policy and remuneration paid 2022 The deferred portion payable at the end of the period (IDE) is determined as follows: IDE = ID x MD Where MD is the final multiplier given by the average of the annual multipliers recorded over the three-year period in relation to the performance achieved based on the chart of annual Eni tar- gets, as shown in the chart below. The levels of the payable deferred portion, depending on the performance levels achieved throughout the three-year period, are shown in the table below26.

(26) The 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 CHART 13 – DEFERRED INCENTIVE MULTIPLIER 85% 130% 230% 85 70 100 150 Annual Performance Budget Annual Multiplier CHART 12 – DEFERRED INCENTIVE - TIMELINE PERFORMANCE AND VESTING PERIOD YEAR T  Attribution of STI deferred portion YEAR T+1 YEAR T+2 YEAR T+3  Payment of STI deferred portion CHART 14 – LTI SHARE-BASED PLAN TIMELINE PERFORMANCE AND VESTING PERIOD YEAR T  Award of shares YEAR T+1 YEAR T+2 YEAR T+3  Granting of shares

37 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex Performance conditions As to the performance conditions, the relative performance parameters used in the previous Plan, assessed in relative terms to the Peer Group, were integrated with four new absolute pa- rameters assessed over the three year-period, with a view to better balancing the targets in accordance with the stakeholders’ expectations and supporting the implementation of the Stra- tegic Plan. The targets and related weightings are as follows: 1) 25% Market target: linked to the Total Shareholder Return (relative) 2) 20% Industrial target: Net Present Value of proven reserves (relative) 3) 20% Economic-financial target: organic Free Cash Flow (absolute) 4) 35% Environmental sustainability and Energy transition targets, made up as follows: 4.1) 15% Decarbonisation target: CO2eq. Emission Intensity Upstream Scope 1 e Scope 2 equity (absolute); 4.2) 10% Energy Transition target: development of electricity generation from renewables (absolute); 4.3) 10% Circular Economy target: Important projects (absolute). For the two relative parameters, the reference Peer Group is described in the section “Market References and Peer Group” (Apache, BP, Chevron, ConocoPhillips, Equinor, ExxonMobil, Mara- thon Oil, Occidental, Shell and Total). The descriptions of each indicator are given below: 1) The difference between the TSR of 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 ρco,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). This indicator allows to neutralize the potential effects on the TSR of each company of develop- ments in the respective stock market. This results is achieved taking into account the correla- tion between the stock and the market over the same three-year period by using the correlation coefficient. 2) Net Present Value (NPV) of proven reserves vs. the Peer Group, measured in terms of the annual unit value ($/boe), calculating the average annual performance over the three-year period. For the two relative indicators, the Peer Group is the same as described in the “Market References and Peer Group” section (Apache, BP, Chevron, ConocoPhillips, Equinor, Exxon- Mobil, Marathon Oil, Occidental, Shell and Total). 3) Organic Free Cash Flow cumulated in the three-year reference period compared to the equiv- alent 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. The verification of Free Cash Flow targets is conducted net of exogenous variables, using a gap-analysis approach approved by the Remuneration Committee, in order to enhance the effective corporate performance deriving from the management action. 4) Decarbonisation objective: measured as the final value of Upstream Scope 1 and Scope 2 GHG Emission Intensity at the end of the three-year period (tCO2eq./kboe) relating to the production of hydrocarbons in operated and unoperated assets, compared with the same Objectives of LTI share-based Plan

38 Eni Report on remuneration policy and remuneration paid 2022 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. 5) Development of electricity generation from renewable resources, measured in terms of MW of installed capacity 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 attribution and kept unchanged over the performance period. 6) Circular economy objective: measured in terms of progress of three important projects com- pared with the progress expected in the first 3 years of the Strategic Plan approved by the Board of Directors in the year of attribution and kept unchanged over the performance period. Long-Term Share Plan 2020-2022 2022 LTI awarded - targets of absolute objectives According to the provisions of the Information Document of the 2020-2022 Long-Term share Plan, available on the Company’s website, table 10 shows the three-year performance levels of the absolute objectives of the second award of the Plan (award 2022, with performance period 2022- 2024). The mentioned performance targets were approved by the Board of Directors, on the proposal of the Remuneration Committee, at the meeting of March 17, 2022.

Incentive mechanisms and levels The annual award of shares is calculated using the following formula: FR x %ITarget PriceAttr No. Awarded shares = Where FR is total fixed remuneration, ITarget is the incentive percentage at target performance level, which is set to 150% of total fixed remuneration for the Chief Executive Officer, and PriceAttr is the price of the award calculated as the average of the daily official prices (source: Bloomberg) recorded in the four months before the month in which the Board of Directors approves the plan rules and the award to the Chief Executive Officer. Assignable shares at the end of the three-year vesting period are calculated using the following formula: No. Assigned shares = No. Awarded shares x Mf In which the multiplier (Mf) is equal to the weighted average of the multipliers of each parameter.

39 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex For relative parameters (linked to TSR and NPV of proven reserves), each multiplier may be between zero and 180%, with a threshold set at a median level, in accordance with the scale shown below.

40 Eni Report on remuneration policy and remuneration paid 2022 The Plan Rules provide that 50% of the shares assigned at the end of the vesting period shall remain restricted for a period of 1 year from the date of assignment for the Chief Executive Of- ficer and Managers in service. In the event of early termination for the Chief Executive Officer, due to resignation and not justi- fied 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 assignment of Eni shares of each award will be prorated with respect to the period of perma- nence in office, according to the results verified over the same period. NON-MONETARY BENEFITS There is a life insurance policy and an insurance policy against permanent disability due to injury or illness contracted in the workplace or elsewhere. Also provided, as per provisions contained in the national collective bargaining agreement and the supplementary company agreements for Eni senior managers, is enrolment in the supplementary pension plan (FOPDIRE)28 and in the supplementary health plan (FISDE)29, together with a company car for business and personal use. 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, which comprises a short-term incentive deferral and long-term share incentive determined using internationally recognized methodologies for remuneration benchmarks. The pay mix, calculated by considering fixed remuneration as the base, is weighted significantly towards the variable components, with a dominant weighting attributed to the long-term com- ponent, as shown in the figure below.

41 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex PAYMENTS DUE IN THE EVENT OF TERMINATION OF OFFICE OR EMPLOYMENT30 Severance package: For the Chief Executive Officer: indemnity in the event of early termination and/or non-re- newal of the office, set at two years of fixed remuneration for the position. For the General Manager, if appointed: indemnity in the event of the consensual termination of the management relationship, unchanged compared with the previous term (two years of fixed remuneration plus short-term incentive), taking due account of the provisions of the appropriate national collective bargaining agreement providing for a maximum of three years of total actual remuneration, including fixed remuneration, short- and long-term vari- able incentives, benefits31. Non-compete agreement: During the 2020-2023 term, in order to safeguard the Company’s interests, non-compete agreements may be maintained and/or put in place, to be activated at the sole discretion of the Board through the exercise of an option right, with a fixed payment determined in relation to the obligations established under the agreement (duration and scope of the re- strictions on business activities and Countries of operation) up to a maximum, for each year of obligation, equal to fixed remuneration plus a component determined in line with the average annual performance of the STI Plan over the previous term, varying between €500,000 (target) and €1,000,000 (maximum). The payment for the option right shall not exceed €300,000. MANAGERS WITH STRATEGIC RESPONSIBILITIES For Managers with strategic responsibilities, the 2020-2023 Remuneration Policy Guidelines are unchanged on those 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 senior managers. In particular, the Long-Term Share Incentive Plan and Short-Term Variable Incentive Plan with deferral – intended for the Chief Executive Officer – will also apply to Managers with strategic responsibilities. (30) Information provided in accordance with Article 123-bis, paragraph 1, letter i), of the Consolidated Law on Finan- cial Intermediation, as specified under note 22 above. (31) In cases of termination not due to just cause, protections laid down by national collective bargaining agreements provide for up to a maximum of 36 months of total remuneration (fixed remuneration, short- and long-term variable incentives, ben- efits), including the amount due by way of notice indemnity (equal to a minimum of 6 months, up to a maximum of 12 months, depending on seniority). Incentive Plans closely consistent with those provided for the CEO/GM Consistent with European Recommendation Consistent with national bargaining collective agreement

42 Eni Report on remuneration policy and remuneration paid 2022 FIXED REMUNERATION Fixed remuneration is based on roles and responsibilities assigned taking into consideration a graduated and a generally median to below-median positioning versus national and interna- tional executive markets for comparable roles. It may be updated periodically, during the an- nual salary review for all managers. Given current market comparators and trends, the Guidelines provide for a selective approach to salary reviews, while maintaining appropriate levels to ensure competitiveness and motiva- tion. More specifically, proposed actions will include measures to adjust fixed/one-off remu- neration for those in positions that have seen a significant increase in 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 senior managers and supplementary Company agreements. VARIABLE INCENTIVE PLANS Short-Term Variable Incentive Plan with deferral The Short-Term Incentive Plan with deferral, already described for the Chief Executive Officer, will be maintained in 2022. The targets set for Managers with strategic responsibilities are consistent with those assigned to the Chief Executive Officer, on the basis of the same bal- ancing of stakeholder interests, in addition to relevant individual targets, consistent with the responsibilities of the role and the provisions of the Company’s Strategic Plan. 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 2020-2022 Long-Term Performance Share Plan. The Plan is directed at managers who are critical for the business and envisages three annual awards, starting in 2020, with the same performance conditions and character- istics 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 the level of their role and is limited to a maximum of 75% of fixed remuneration, with the maximum award corresponding to 135% of fixed remuneration, calculated with reference to the grant price of the shares. NON-MONETARY BENEFITS In line with national collective bargaining agreement and supplementary Company-level agree- ments for Eni managers, the Policy Guidelines provide for life and disability insurance cover (due to workplace or other injury or illness), as well as enrolment in the supplementary pension plan (FOPDIRE) and health plan (FISDE), together with a company car for business and personal use, and the possible assignment of housing based on operational and mobility requirements. Fixed remuneration based on roles and responsibilities

43 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex PAY MIX In line with market best practice, as well as the valuation methods used for the Chief Executive Officer, the average target pay mix and maximum of the remuneration package for Managers with strategic responsibilities who are eligible for the Short-Term Monetary Plan with deferral and the Long-Term Performance Share Plan features a balance between fixed and variable com- ponents that is weighted towards medium-long term variable incentives. PAYMENTS DUE IN THE EVENT OF CONSENSUAL TERMINATION OF EMPLOYMENT Managers with strategic responsibilities, as well as Eni senior managers, are entitled to sever- ance benefits for employment termination established by law and applicable national collective bargaining agreements together with any termination indemnities agreed on an individual ba- sis, in accordance with the criteria established by Eni for cases of early termination, within the limits of protections envisaged by applicable national collective bargaining agreements32 and consistent with application criteria of the Italian Corporate Governance Code (Recommendation no. 27, letter f). These criteria take into account the position held, statutory retirement age and actual age of the manager at the time employment is terminated and the annual remuneration received. 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 dura- tion 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 account33. (32) In cases of termination not due to just cause, protections laid down by national collective bargaining agreements pro- vide for up to a maximum of 36 months of total remuneration (fixed remuneration, short- and long-term variable incentives, benefits), including the amount due by way of notice indemnity (equal to a minimum of 6 months, up to a maximum of 12 months, depending on seniority).

44 Eni Report on remuneration policy and remuneration paid 2022 This Section is subject to the non-binding vote of the Shareholders’ Meeting of May 11, 2022. Introduction The Committee positively acknowledged the non-binding vote expressed by the shareholders during the Shareholders’ Meeting of May 12, 2021 on the second section of the Report relating to the remuneration paid in the previous year. In the engagement meetings held in relation to the results of the vote, investors illustrated the reasons for their vote on the implementation of remuneration policies for the year 2020, explain- ing that the deferral measures of a significant part of the variable remuneration, implemented both in 2020 and 2021, were not deemed sufficient, considering the revision of targets under- taken in light of the pandemic. They therefore hoped for voluntary reduction of wages, or the exercise of discretion in defining the final pay-outs of the incentive systems. The outcome of the meetings confirmed a general appreciation of the aims, overall structure and specific articulations of Eni’s Policy, with regard in particular to the balance between the economic-financial indicators and those aimed at measuring energy transition. The Committee greatly appreciated the feedback received, drawing useful information on the need to maintain an effective dialogue with investors, especially in exceptional circumstances, in order to verify their orientations and receive feedback on choices made. In drafting the 2022 Report, the aim of further improving the description of the methodology and assessments carried out when verifying the performance was also shared, in compliance with the mandate of the Committee. In accordance with the Consob Issuers Regulation, this Section reports the remuneration on an accrual basis, showing fixed remuneration accrued in 2021 and short and long-term variable in- centives accrued with respect to the final performance in 2021 and payable/assignable in 2022. As regards the 2022 Short-Term Incentive accrued in 2021 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 individual performance at target level. As regards the Long-Term Share Incentive awarded in 2019 with accrual period 2019-2021, since the final results of the parameter NPV of Proven Reserves is available only after the pub- lication 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 2021 result of the parameter NPV of Proven Reserves at target level. The incentives that will actually be paid/assigned in 2022, both relating to the Short-Term Plan and the Long-Term Share Plan, will be disclosed in the 2023 Remuneration Report. Moreover, as required by Consob Regulation, Section II of the Report shows the development of Directors’ remuneration over the past three years as compared to that of Eni’s employees in Italy. Section II – Compensation and other information

45 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex Finally, with reference to the content of pages 46 and 50 of the 2021 Remuneration Report, Sec- tion II of this Report provides additional information on the implementation of the remuneration policies for 2020, concerning the values of incentives actually paid/assigned for which, at the date of approval of the 2021 Report, the data necessary for verifying the performance results were not available. Implementation of the 2021 remuneration policies Implementation of the 2020 remuneration policies for Directors, Chief Operating Officers and Managers with strategic responsibilities, as verified by the Remuneration Committee in con- junction with its periodic assessment as called for the Corporate Governance Code, was in line with the Remuneration Policy approved by the Shareholders’ Meeting on May 13, 2020 for the whole 2020-2023 term, taking account of the provisions of the resolutions of the Board of Directors of June 4, and July 29, 2020, concerning, respectively, remuneration for Non-Execu- tive Directors serving on Board committees and the remuneration of Directors with delegated powers in compliance with the criteria and maximum limits approved by the shareholders. Disclosure on remuneration changes For the Chairwoman and the Non-Executive Directors and Statutory Auditors, there are no changes in remuneration in 2021 compared to the previous year, their remuneration having remained un- changed. For the Chief Executive Officer and General Manager, fixed remuneration for 2021 remained un- changed, while overall 2021 remuneration, including incentives paid on verified performance, showed an increase of 43% over 2020, mainly reflecting the assignment in 2021 of the long-term share-base incentive plan awarded in 2018 (while the 2017 award related to verified performance was not as- signed in 2020). For Chief Operating Officers, the change in remuneration in 2020-2021 was mainly made up of com- ponents referrable to the previous role, since the COO position was established on July 1, 2020. As regards the COO of Energy Evolution, the change also reflects a change in person taking place on January 1, 2021.

46 Eni Report on remuneration policy and remuneration paid 2022 For Eni employees in Italy, the change in total remuneration in 2021-2020 came to an average +0.9%34, against -2.5% in 2019-2020. In 2021, the Company had excellent performance and accelerated its transformation strategy. In par- ticular, Eni reported an EBIT of €9.7 billion and an adjusted net profit of €4.3 billion, the highest since 2012. Strong cash generation made available €7.6 billion of organic free cash flow, which allowed to accelerate the growth of green businesses and ensure a shareholder remuneration in line with pre- pandemic levels, while reducing the debt ratio to 20%, compared to 31% last year. From the point of view of safety, SIR (an indicator weighting injuries also on the basis of their sever- ity) recorded the best performance over the last five years, confirming Eni’s commitment to raising awareness and disseminating the culture of safety. The results achieved in 2021 confirm the effectiveness of the strategy launched since the beginning of the pandemic. VERIFICATION OF 2021 PERFORMANCE FOR THE PURPOSE OF THE ACCRUAL OF INCENTIVES PAYABLE AND/OR ASSIGNABLE IN 2022 This section covers the verification of results for 2021, as approved by the Board of Directors on March 17, 2022 for the purpose of incentives payable/assignable and/or awardable in 2022 to the Chief Executive Officer and General Manager, Chief Operating Officers and other Managers with strategic responsibilities.

47 Letter from the Chairwoman | Foreword | Executive Summary | Section I | Section II | Annex SHORT-TERM INCENTIVE PLAN WITH DEFERRAL (STI PLAN) 2022 Verification of objectives 2021 The verified performance related to objectives assigned in 2021 to the Chief Executive Officer and General Manager was approved by the Board, based on a recommendation by the Remu- neration Committee, on March 17, 2022 and resulted in a performance score of 135 points on the measurement scale used, the target and maximum performance of which are 100 and 150 points, respectively. The table 15 shows the weightings and performance level achieved for each objective. The verification of objectives was conducted using the gap-analysis methodology approved by the Remuneration Committee. The use of gap analysis, applied to the main economic and finan- cial metrics, is part of the effort to monitor performance and provides for the netting out of ex- ogenous factors in order to ensure the comparability of the results with the assigned objectives. Exogenous factors include for example the commodity price scenario and the exchange rate or refer to events that by their nature can alter performance such as factoring and extraordinary portfolio transactions. The following are the main results for each objective:  EBT: improvement of performance over the target particularly in the Global Gas & LNG sector, reflecting portfolio optimization and the renegotiation of contracts that made it possible to ben- efit from the extreme volatility of the gas market, as well as widespread cost reduction actions.  Free cash flow: improving over the target by way of improvements in the economic perfor- mance and as a result of decreases in investments.  Hydrocarbon production: in line with target.  Incremental renewable installed capacity: better than target performance reflecting the sig- nificant acceleration of growth by way of targeted acquisitions that can be quickly integrated into Eni’s portfolio.

DEFERRED SHORT-TERM PLAN (STI PLAN) 2019 Verification of objectives 2019-2021 - deferred portion The 2019 STI Plan calls for the deferral of a 35% portion of the incentive over a three-year vesting period, upon verification of annual performance levels of Eni in the 2019-2021 period. On March 17, 2022, the Board of Directors, acting on the proposal of the Remuneration Commit- tee, approved a 2021 performance score of 135 points resulting in a 2021 partial multiplier of 200%. With reference to the already verified performance levels of 2019 and 2020, the final multi- plier to be applied to the deferred portion awarded in 2019 for payment in 2022, came to 197%, as shown in table 16.

For the 2019 award, with 2019-2021 performance period, on March 17, 2022 the Board of Directors, as verified and recommended by the Remuneration Committee, approved the three-year performance of the TSR indicator, calculated in accordance with the criteria set under the plan, at the sixth place within the Peer Group for a multiplier of 80%. The final multiplier will be determined after verification of the NPV target in 2021 as available after the publication of the financial statements of all the companies in the Peer Group.
