"We take care of our people every day and share the value with those who create it"

Susanna Dorigoni

Dear Shareholders,

As Chairman of the Remuneration and Appointments Committee (hereinafter Committee), I am pleased to present to you the A2A Report on the remuneration policy for 2025 and on the remuneration paid in 2024 which this year includes an Executive Summary aimed at making A2A's commitment to remuneration for its People increasingly usable and transparent.

2024 was a year characterised by exceptional business performance, which allowed the Group to achieve extremely satisfactory results, with an increase of 15% in Group Gross Operating Margin compared to last year and 23% in Group Operating Profit. The positive business performance in the first year of the 2024-2035 Strategic Plan makes us confident of the path started and the long-term success of A2A, supported by a competitive ecological transition strategy based on the pillars of the circular economy and the energy transition.

The Group also received significant recognition from the market, with share price appreciation reflecting investors' confidence in the Strategic Plan and long-term growth prospects. Shareholder value creation will be further strengthened by the sustainable increase in the dividend per share, fuelled by the Group's structural growth path.

The past year has also been an important step from the point of view of the Group's progress on ESG issues, which retain a key role in the development of A2A. The company adheres to all the major ESG indices at a global level, confirming also in 2024 its constant path of consolidation within the ratings drawn up by MSCI, Standard Ethics, ICI - ESG Identity Corporate Index, CDP and Standard&Poor's. As proof of the Group's commitment to developing best practices in the ESG sphere, A2A has obtained the following awards: Best ESG Rating Award - Milano Finanza; Special Generation Z Award - Oscar di Bilancio 2024; Sustainability Yearbook Member - Standard&Poor's; Leading Companies - EUPD Research Energy; Research & Innovation Award - Top Utility.

2024 results confirm once again the effectiveness of a balanced, well-diversified business model that is attentive to the correct balance between quality of the offer, operational efficiency, innovation and social responsibility.

In this context, A2A maintained the utmost attention to its People, continuing on the path of enhancing the equity and attraction/retention dimension in the Reward sphere. The work of the Committee was able to focus on the continuous improvement of our Remuneration Policy, thanks also to the fundamental ongoing and open dialogue between the Company and its shareholders.

In particular, the Committee's efforts and commitment have led to some significant results, of which I would like to share with you the main areas and aspects:

• • Widespread Share Ownership Plan. We have drawn up a Widespread Share Ownership Plan involving all employees, which will be submitted for your approval at the Shareholders' Meeting on 29 April 2025. The plan called A2A Life Sharing, reaffirms the sense of sharing value with those who create it of our Life Company and represents a fundamental element of our long-term strategy, fully aligned with ESG (Environmental, Social, Governance) objectives, with a particular focus on S (Social) and G (Governance). It is a key project for the Group's long-term success, which confirms A2A's willingness to share corporate successes with its employees, strengthening the sense of belonging and encouraging everyone's contribution to the achievement of strategic objectives.
• • Equal pay and equal opportunities. Our commitment to gender equity has produced tangible results, also thanks to the in-depth analyses conducted in recent years on the "Equal Pay Gap" and the "Adjusted Pay Gap". The path has continued in the name of increasingly transparent remuneration policies inspired by the principles of equity and inclusion, ensuring competitive conditions for employees. We will continue to monitor and improve our practices to maintain this standard of absolute excellence, also taking into account the objective of the Strategic Plan to maintain an Adjusted Pay Gap of less than 1% by 2035 and which positions A2A as a "lead practice" compared to companies in the sector and on the European scene. Maximum attention has been paid to the gender equality certification process, which in 2024 was extended to 13 Group companies in which over 84% of our people work.
• • Reputation and Employer Branding. In 2024, the Company achieved extraordinary results also from the point of view of employer branding, with the achievement of the Top Employers certification, which reinforces our reputation for excellence. This result is the result of a constant investment in the wellbeing of employees and in the enhancement of talents, which is also ensured by the

Remuneration Policy adopted by A2A. Other DE&I-related awards include the Best Company Award - Index Parks, recognition by the UNHCR and the "Welcome. Working for refugee integration". We are also proud to have received the 'The Best First Time Responder Award' at the Workforce Transparency Awards, sponsored by the Thomson Reuters Foundation, in which our corporate practices aimed at fair and transparent human resources management were praised.

• Welfare: In 2024, the Company strengthened its welfare plans for the benefit of its people with the "A2A Life Caring" project, a plan to support the parenthood of our employees that includes investments of 120 million euros by 2035. A broad, comprehensive and crosscutting programme that testifies to the Group's concrete commitment to supporting the birth rate in a historical phase characterised by the country's continuous demographic decline. The plan takes into account all dimensions of parenting and develops along three lines: 'Time', 'Economic Support' and 'Culture'. The agreement provides for an additional month of 100% paid maternity leave for all mothers and a month of 100% paid leave for all new fathers.

The Group will also contribute to the expenses incurred by employees for services related to their children's education - such as books, school fees, nursery schools, babysitters - differentiated by age group and up to the age of eighteen.

• • MBO Bonus Pool Executives. In 2024, we studied expanding the scope of the bonus pool beneficiaries to include the management population, with the aim of ensuring greater internal equity and more widespread recognition of the value of individual and collective contribution. The new model will go live in 2025 and will ensure better cascading of Business Plan targets with all the Group's People.
• • Link between ESG and incentive systems. In order to further consolidate the link between the Remuneration Policy and ESG issues, which represents one of the strategic pillars for achieving the long-term objectives set out in the 2024-2035 Business Plan, we considered it a priority to ensure that at least 25% of the short-term variable incentive for First Lines is anchored to quantitative and measurable

ESG KPIs (10% for the remaining management personnel). Furthermore, with the inclusion of objectives relating to Strategic Projects in the ESG field in the General Manager's profile, the overall weight of the related KPIs is equal to 50%. This reflects our business model that places environmental, social and governance sustainability at the centre through everyone's commitment to integrating responsible practices into business performance.

I find it important to stress once more the Committee's willingness to listen, gather and promptly assess the input provided by investors, through periodic engagement cycles with institutional investors and proxy advisors, as well as with the post-meeting examination of the voting results. In this regard, based on the feedback received and with the aim of consolidating alignment with market best practices, the Committee is considering further actions on the Remuneration Policy in the future. In particular, from an evolutionary perspective, reflections will focus on the

opportunity to introduce a long-term incentive mechanism based on financial instruments, with the aim of increasing the alignment of interests between Shareholders and Management, and to further strengthen the long-term orientation through Share Ownership Guidelines. For 2025, moreover, the Committee intends to continue its commitment by further deepening the welfare offer dedicated to its Staff, with the aim of fostering an increasingly welfare-oriented approach.

Thanking Vice-Chair Giovanni Comboni and Board Member Elisabetta Pistis, as well as the Board of Statutory Auditors, who have generously lent the Committee their constant availability, professionalism, passion and experience, I trust in your support for the proposals identified and I thank you, also on behalf of the Board of Directors, for the endorsement you will express of the Remuneration Policy, further renewed following the engagement meetings held with Company stakeholders.

Chair of the Remuneration and Appointments Committee Susanna Dorigoni

Executive Summary

Principles of the A2A Policy

A2A's mission is to lead the ecological transition by encouraging virtuous circles between territory, companies, people and institutions with the aim of generating a positive impact on the lives of people, cities and the Planet. We take care of our customers and our people every day and are committed to spreading a new culture that steers individual behaviour towards a sense of community.

The Remuneration Policy of the A2A Group (hereinafter also the "Group") is adopted by the Board of Directors, following an investigation and on the proposal of the Remuneration and Appointments Committee, and is defined in line with the business strategy, with the governance model implemented and with the guidelines provided by the Corporate Governance Code of Listed Companies.

Aims of the A2A Remuneration Policy

• Promoting the pursuit of corporate targets, sustainable success and the improvement of results in the medium to long term;
• Pursuing value creation for all Group stakeholders (shareholders, employees, suppliers, customers, local communities);
• Incentivising responsibilities, actions and behaviour towards predetermined, measurable goals consistent with the Group's Strategic Plan and Sustainability Plan;
• Attracting, retaining and motivating people with high professional qualities, fostering their commitment;
• Strengthening the sense of belonging and "teamwork" by company Management;
• Stimulating actions and behaviour in line with the Group's values, in compliance with the principles of inclusion and diversity, equal opportunities, meritocracy, fairness, as set out in the A2A Code of Ethics.

2025 Remuneration Policy - Additions

The 2025 Remuneration Policy is defined in constant alignment with legal and regulatory provisions, also taking into account the results of the shareholders' meeting vote, the indications of shareholders and proxy advisors, as well as market best practices, with a view to continuous improvement.

A number of changes have therefore been made to this Report, with a view to an ever-better representation of information and greater clarity for all stakeholders. Below is a summary of the main new elements:

Remuneration Review of the CEO/GM MBO incentive card Policy

The 2025 Policy introduces some innovations related to the CEO/GM incentive card, with the aim of increasing a greater focus on the strategic projects most relevant to the long-term success of A2A and in order to strengthen the alignment and coherence of the operating mechanism among the recipients of the MBO system. In particular, the changes introduced are as follows:

• inclusion of the economic-financial KPI FFO/Net Debt¹ in the CEO's sheet. The EBITDA parameter is maintained in the data sheet as a GM;
• in conjunction with the introduction of the MBO Executives Bonus Pool, the incentive strategy of the DG card was also updated. The bonus fluctuations are extended, providing for a minimum threshold equal to 60% of the bonus target and a cap equal to 140% of the bonus target. In order to assess this Policy update, the Remuneration and Appointments Committee reviewed the market practices of the FTSE MIB listed companies, which revealed substantial consistency with them;
• revision of the project indicators within the GM's incentive sheet. The Committee considered it reasonable to also consider project KPIs for 2025 related to the Circular Economy and Energy Transition strategic drivers, considered most relevant to the sustainable success of the organisation. These objectives are part of the ESG framework, therefore, the overall weight of ESG objectives in the DG sheet is 50%.

Pay transparency and Gender Pay Gap

The A2A Group ensures a working environment that guarantees equal opportunities, inclusion and absence of discrimination: as of 2024, an analysis of the salary differences between people in comparable roles, not justified by objective elements and not attributable to the correct application of the Remuneration Policy, has been carried out throughout the Group, including the companies AEB and Acinque, with the collaboration of Mercer as an independent expert. The results demonstrate success in applying wage mitigations and applying gender-neutral remuneration policies. The broadening of the scope of the analysis - introduced by A2A as from 2023 - and the inclusion of the KPI relating to the Gender Pay Gap within the Group's 2024-35 Strategic Plan confirm the ambition to consolidate the excellent results achieved, further strengthening the Group's commitment to the issues of pay transparency and pay equity.

1.FFO/Net Debt: FFO/Net Debt ratio as defined by S&P. Funds from operations (FFO) determined as: (+) EBITDA (-) Provision for credit devaluation (-) Cash taxes (-) Gross financial expenses per cash. Net Debt determined as: (+) Gross financial debt (+) Debt from IFRS16 (-) Cash and cash equivalents (+) Hybrid nominal value, 50% (+) Decommissioning and Landfill Funds (+) Severance indemnity fund and employee benefits (+) Financial guarantees on unconsolidated debt

MBO in executive Bonus Pool

Policy 2025 introduces a new MBO Bonus Pool system for Executives with Strategic Responsibility (Key Executives), aligning it with the model already applied to Non-Executives. This innovation was introduced with the aim of:

(i) Align individual objectives with those of the company;

(ii) Enhance individual excellence;

(iii) Ensure consistency with the MBO Bonus Pool system of the non-management population;

(iv) Create a structured and reserved space dedicated to the development of skills.

The Bonus Pool, defined as the sum of the MBO targets assigned, may vary based on a Correction Factor K (hereinafter referred to as Factor K) linked to EBITDA and Group CAPEX, with an incremental/decremental effect or access gate if it is below a minimum level.

The Key Executives incentive card includes economic-financial objectives (with a weight between 40-50%) different from those considered in Factor K, ESG objectives (with a minimum weight of 25%) and individual objectives (with a weight between 25-35%). The results of the card determine the inclusion in 6 performance bands, with redistribution of the Bonus Pool and cap on the payout. The MBO process includes a phase called Mid-Year Review that allows you to adjust the objectives exceptionally and in certain cases such as: exogenous events, organizational changes, strategic, or priority changes. In the event that this review impacts the objectives of the Key Executives, an authorization step in the Nomination and Remuneration Committee (CRN) is necessary. During the MBO reporting process, after the Manager's evaluation, there is a phase called "Band Distribution Analysis" in which the DG/ AD, for the First Lines, can change the resulting band by a positive or negative level, in order to take into account the level of challenge, personal effort and evaluation of skills. In this case, an authorisation step in CRN is required for Key Executives. In the event that the skills assessment is only equal to the minimum level, the payout is expected to be halved.

Introduction of the Widespread Share Ownership Plan

The Company intends to launch, in line with national and international best Practices, a threeyear widespread shareholding plan (2025-2027) in order to encourage the involvement of our People in the achievement of corporate objectives, affirming, in particular, the value of shareholding as an effective tool to promote commitment, affiliation and alignment between the interests of shareholders, management and the generality of employees.

Our Widespread Share Ownership Plan includes two fundamental moments within each cycle: the first provides for the recognition of shares without any additional cost for employees and the second gives them the possibility to purchase by receiving matching shares according to a defined proportionality and according to criteria that are more favorable towards the qualification of Workers/Employees/Managers compared to that of Managers (including Strategic Managers). This Plan will be accompanied by a financial education program and an information/training campaign to encourage more informed participation in the initiative.

Link between Remuneration Policy and strategy/business model

The A2A strategy is aimed at creating value for all stakeholders and aims to make a significant contribution to the necessary cultural and infrastructural change for the country and communities, thanks to a diversified business model that encompasses the entire energy, environment and water value chain.

Our presence through key services for people's daily lives drives our growing commitment to make our results measurable. We constantly focus and align with ESG criteria, in a logic of integration of economic, social and environmental aspects in corporate decisionmaking processes, strategy definition, governance and the definition of our business model.

As a Life Company we continue our commitment to the ecological transition, placing it at the centre of our strategy and services, through major investments in

renewable energy, upgrading and digitisation of infrastructure, limiting the use of landfills, using green hydrogen in the energy mix and reducing water loss.

The Remuneration Policy supports the achievement of the guidelines defined in the Company's 2024-2035 Strategic Plan by promoting, through an appropriate balancing of performance parameters of the short to long-term incentive systems, the alignment of Management interests to the priority target of creating sustainable value for shareholders in a medium-long term perspective. In support of the Strategic Plan guidelines, the short-term CEO/GM incentive plan includes project KPIs for 2025 linked to the Circular Economy and Energy Transition pillars and related strategic drivers, which fit into the ESG framework, bringing the overall weight of the related ESG targets in the DG scorecard to 50%. In addition, the Long-Term Incentive Plan includes a specific composite target on ESG issues (overall weight 30%), articulated on specific targets related to decarbonisation processes, energy transition and the circular economy.

Alignment with market practices

The preparation of the Guidelines on remuneration and the evaluation of the policies implemented are carried out - as previously indicated - with the support of Mercer, an external advisor specialized and leader in the sector, using salary benchmarks.

The analyses conducted are aimed at defining a remuneration offer capable of ensuring the Group's competitiveness on the market, within the framework of a remuneration policy that can support the ability to attract the best talent and retention of key resources for the company's success. In particular,

remuneration levels are defined on the basis of benchmark analyses that are updated periodically to ensure consistency of remuneration packages.

For Executives with Strategic Responsibilities, specific peer groups are identified, confirmed each year in line with the leading companies included in the Mercer databases on the basis of criteria and methods of comparison with the market reviewed in line with the evolution of the Group, management and operational complexity and the organisational model adopted. In particular, companies deemed significant and comparable with A2A in terms of type of sector and business, size and competitiveness in the labour market are considered.

The peers considered in the analyses carried out for the CEO/GM and Executives with Strategic Responsibilities are as follows:

Pay for performance

With a view to increasing transparency towards stakeholders, the following tables illustrate the performance of the company's results and their correlation with the remuneration of the CEO and General Manager, with details of both fixed and short-term variable remuneration.

Comparison of remuneration paid to the CEO and General Manager and company performance, period 2020 - 2024

	2020	2021	2022	2023	2024
A2A Group revenues (in M€)	6,848	11,549	23,156	14,758	12,857
EBITDA of the A2A Group (in M€)	1,200	1,428	1,498	1,971	2,328
Operating profit of the A2A Group (in M€)	554	660	682	1,017	1,317

Note 1: The 2022 figures are "restated" to reflect the IFRS 5 reclassification of the water cycle.

Note 2: The values indicated for the year 2020 refer to the annual remuneration package of Renato Mazzoncini, in office as of May 13, 2020: for this year, for the fixed compensation, the value resolved by the Shareholders' Meeting and the Board of Directors was considered; for the variable compensation, the value re-proportioned on the full year was considered and not the actual pro-rata paid. For 2023 and 2024 variable remuneration, the annual pro-rated value of the assigned LTI was not taken into account as it will only be paid at the end of the three-year period if results are achieved; for CEO/GM, the value of the MBO 2024 was considered.

The tables and the graph show stable remuneration for the Chief Executive Officer and General Manager in the period 2020-2024, to be compared with a significant growth trend in company results in terms of EBITDA and operating income, particularly marked in 2022, 2023 and 2024.

Working conditions of employees

A2A makes the protection of the working conditions of its employees one of the cornerstones of its policies. To this end, it is recalled that the Group, which operates mainly in Italy, applies the main national contracts for the sector as well as numerous second level agreements.

In particular, respect for the working conditions of employees is embodied in various measures which the Group has been committed to for some time, such as:

• alignment of everyone in the Group to the corporate targets;
• strong focus on female representation both in positions of responsibility and overall

representation included in the targets of Group managers;

• analysis and corrective action to ensure gender equity in pay;
• strengthening welfare instruments and strong focus on parenting needs;
• strict control of injuries, included in the targets of the Group managers;
• improving the quality of life in the workplace and raising awareness of sustainability "good practices" (e.g. separate waste collection with smart bins, water dispensers to contain plastic use, printer reduction, extension of LEED and WELL certifications, etc.);
• raising awareness of health issues, through communication on the importance of prevention and training on healthy lifestyles, as well as tools for monitoring general health status.

Top Employer 2025

We are proud to have received the Top Employer 2025 certification, joining an exclusive club of around 2,400 certified companies worldwide and only 150 in Italy. This is an important international recognition, which rewards excellence in human resources management strategies and practices.

The audit assessed 6 People dimensions divided into 20 sections for a total of over 250 areas of investigation, including corporate strategy, change management, work environment, talent acquisition and development, employee well-being and listening. A2A meets international standards in all areas, with particular success in the categories of diversity, equity, inclusion and sustainability.

"Top Employers" represents a further step forward in the path of growth and continuous improvement: it is the first stage of a three-year journey that offers the Group a significant opportunity for analysis and further development with the aim of constantly growing as a Life Company, consolidating A2A's commitment to valorising people and creating an inclusive and sustainable work environment.

A2A places its people at the centre of its corporate strategy, constantly striving to create a fair, inclusive, healthy and sustainable working environment. The Company adopts best practices to ensure adequate wage growth, reduce pay inequalities, taking into account individual merit, and promote fair employment opportunities. Some important actions carried out by the company fit into this context:

• review of the formalized variable incentive system (MBO), in the context of a Bonus Pool, with extension to the population of employees with Executive qualifications, already implemented in 2024 and extension to all Managers starting from 2025;

• disclosure of the relationship between the remuneration of the Chief Executive Officer and General Manager and the average remuneration of employees;
• in-depth analysis of the Gender Pay Gap from a Gender Pay Equity perspective;
• introduction of the 2025-2027 Widespread Share Ownership Plan.

MBO in Bonus Pool

To support the implementation of the new business plan 2024-35 and in the context of the Group's People Strategy, a review of the Performance Management and MBO processes was implemented in 2023 with the aim of:

• Engaging A2A people towards targets and results of value to the organisation by developing skills and behaviours functional to the business strategy
• Making performance processes scalable and adaptable to A2A different economic-financial and positioning conditions with sustainable incentive costs consistent with business targets and results
• Increase the attractiveness of the Company for high-value resources by creating a participative and inclusive context, but, at the same time, capable of recognising the value of individual and team performance

The highlights of the MBO model are:

• Sustainability of the economic bonus thanks to a very close link to the Company's result (EBITDA)
• Progressive extension of the MBO to the management population and part of the whitecollar population (consistent with the Professional Model)
• Strengthening the responsibility and dialogue between Division Head and Co-worker who become the central actors in the targets-defining process
• Greater focus on targets that may be addressed directly by the activities of MBO grantees
• Addition of a mid-year review, which allows the review of priorities in increasingly changing contexts
• Band Distribution Analysis Phase, which allows you to modify, in line with the Guidelines, the resulting band by one level in positive or negative, in order to take into account the level of challenge, personal effort and assessment of skills

Pay Ratio 2020-2024

Below are the pay ratios between the remuneration of the CEO and General Manager and the average remuneration of employees, calculated with reference to both fixed remuneration and total remuneration. A2A's remuneration multiple, equal to 20.69 in 2024, is slightly down on the previous year (21.33) as a consequence of an increase in the average remuneration amount of employees and the stability of the salary components of the Chief Executive Officer and General Manager.

	2020	2021	2022	2023	2024
Ratio between the fixed remuneration of the CEO/GM and the average fixed remuneration of employees	19.15	19.16	18.86	18.41	17.90
Ratio between the total remuneration of the CEO/GM and the average total remuneration of employees	22.68	22.67	22.54	21.33	20.69

Note: The values indicated for the year 2020 refer to the annual remuneration package of Renato Mazzoncini, in office as of May 13, 2020: for this year, for the fixed compensation, the value resolved by the Shareholders' Meeting and the Board of Directors was considered; for the variable compensation, the value re-proportioned on the full year was considered and not the actual pro-rata paid. For 2023 and 2024 variable remuneration, the annual pro-rated value of the assigned LTI was not taken into account as it will only be paid at the end of the three-year period if results are achieved; for CEO/GM, the value of the MBO 2024 was considered.

Executive Summary

Introduction - Preamble and Regulatory Framework

Section One - 2025 Remuneration Policy

In-depth analysis of the Gender Pay Gap 2024

A2A strongly believes in the importance of gender pay equality at all levels and therefore provides – for all employees – remuneration offers consistent with market standards and internal practices, in order to ensure an adequate level of both external competitiveness and internal fairness.

For years, A2A has been monitoring, with an increasing level of detail, all indicators relating to gender balance, both in terms of pay ("gender pay gap") and professional development, paying particular attention to the career development of women (e.g. in the context of internal management appointments).

In the specific area of the gender pay gap, although in a context of a non-significant gender pay gap by qualification, further analyses were carried out in 2024, conducted by an independent third party with the Mercer's "Equal Pay Gap" methodology, which not only considers the pay gap between men and women on the Group's total population (Raw Pay Gap Analysis), but goes on to determine an "Adjusted Pay Gap" KPI through a statistical regression method (Pay Equity Analysis) that calculates the pay difference between women and men based on those legitimate differentiation factors (e.g., performance, tenure position, city, etc.) and intercepting the bias aspects, i.e. those illegitimate factors to the detriment of pay equity, always taking into account the significance of the analysed samples/clusters.

The analyses conducted covered 14,000 employees of the A2A Group and were extended to the AEB and ACinque Groups for the first time in 2024. This analysis confirmed a very positive Adjusted Pay Gap at Group level (<1%), which positions A2A as a "lead practice" compared to companies in the sector.

Continuing the path towards closing the pay gap to zero, as stated in the Strategic Plan's objective, the evidence of this work has allowed A2A not only to align itself to the regulatory requirements concerning pay transparency with greater awareness, but also to set up a customised action plan on the individual targets identified, so as to decline mitigation measures with the highest level of detail, defining a budget and an annual pay review cycle dedicated to women with remuneration below the average for men in comparable roles (in the absence of legitimate differentiating factors).

2025-2027 Widespread Share Ownership Plan

The Plan that the Company intends to launch, in line with national and international best practices, is aimed at stimulating the participation and active involvement of employees in the achievement of the corporate objectives envisaged in the

Company's Business Plan, affirming, in particular, the value of shareholding as an effective tool to promote commitment, affiliation and alignment between the interests of shareholders, management and the entire employee population, with a view to enhancing and motivating its resources.

The Plan is aimed at employees with permanent employment contracts and apprenticeships of A2A and its subsidiaries that are part of the A2A full consolidation perimeter, as reflected in the Half-Year Financial Report.

Adhesion: A2A will establish an adhesion period (the "Adhesion Period"), during which the Beneficiaries will be able to evaluate the Plan regulations and decide to join them. Membership of the Plan is voluntary.

Initial allocation: the Plan envisages three annual allocation cycles of A2A ordinary shares (2025/2026/2027).

Purchased Shares and Matching Shares: at the same time as the assignment of Initial Shares, A2A will recognize to all Beneficiaries the opportunity to invest further in A2A shares at each annual assignment cycle ("Purchased Shares"). For each batch of Purchased Shares, the Company will also grant the Beneficiaries the right to receive additional Shares, in compliance with the proportions established based on the qualification held by each employee ("Matching Shares").

In particular, for personnel with a blue-collar qualification, a matching share will be recognised for each share purchased. For staff with middle management and white-collar qualifications, 1 matching action is provided for every 3 actions purchased. For Executives there is 1 matching share for every 5 shares purchased. This mechanism is therefore more rewarding for bluecollar staff than for staff with higher qualifications, also to support the loss of purchasing power caused by the strong inflationary dynamics.

The allocation of the Shares is not subject to the achievement of performance conditions by the Beneficiaries and/or A2A.

Lock-up: Initial Shares and Matching Shares will be subject to a lock-up period of 3 years. In line with mapped market practice, the Purchased Shares will instead be subject to a 1-year lock-up period.

Introduction - Preamble and Regulatory Framework

Section One - 2025 Remuneration Policy

The point of view of shareholders and investors

On April 24, 2024, the Shareholders' Meeting voted in favour of Section One of the 2024 Remuneration Report (binding vote).

The figure below illustrates the results of the advisory vote of the Shareholders' Meeting of 2019 (May 13, 2019), 2020 (May 13, 2020), 2021 (April 29, 2021), 2022 (April 28, 2022), 2023 (April 28, 2023) and 2024 (April 24, 2024).

On April 24, 2024, the Shareholders' Meeting also voted in favour of Section Two of the 2024 Remuneration Report (non-binding vote).

The figure below illustrates the results of the advisory vote of the Shareholders' Meeting of 2021 (April 29, 2021), April 28, 2022, April 28, 2023 and April 24, 2024 on Section Two of the Remuneration Report.

A2A ascribes a fundamental importance to the evaluations expressed by each stakeholder and promotes opportunities for discussion with its shareholders, potential investors, analysts and other financial market subjects, in order to ensure due disclosure, acquire opinions and proposals, as well as generally maintain an adequate channel of communication with these subjects.

The discussion with the market contributed to the increase in shareholder support for the Report on Remuneration Policy and Remuneration Paid at the Shareholders' Meeting of April 24, 2024, which received high approval rates on both Section One (98.9% of votes in favour) and Section Two (99.5%).

In this context, A2A analysed the voting results expressed by the shareholders on the Report and the voting indications expressed by the main proxy advisers, intensifying engagement meetings over the last five years to get an in-depth idea of the opinions of the latter and the feedback received from investors and shareholders, as well as to further investigate some specific issues through an open dialogue.

Evaluation of a long-term system shared-based and stock ownership guidelines

The Company, taking into account the recommendations expressed by market representatives during the engagement meetings and with a view to continuous alignment with best market practices, reserves the right to evaluate the introduction of a long-term variable incentive system (LTI Plan) based on shares (in whole or in part) during 2025. Such a system could be aimed at strengthening the link between management remuneration and long-term sustainable value creation, while ensuring even greater alignment with shareholder interests. As part of this assessment, the Company will also examine the possibility of expanding the number of beneficiaries of the LTI Plan, involving additional key figures in the organisation, in order to foster a performance culture oriented towards the medium-long term. In addition, the Company will consider the introduction of Stock Ownership Guidelines for the recipients of the Plan.

The eventual adoption of the LTI Plan and related measures will be subject to in-depth analysis and will be submitted to the appropriate bodies for deliberation, in accordance with current legislation and corporate governance best practices.

A. Preparation, approval and implementation of the Remuneration Policy: procedures, bodies and entities involved

The 2025 Remuneration Policy, defined on the basis of market best practices and in compliance with the principles of fairness, competitiveness, meritocracy, sustainability and transparency, has the aims illustrated in the Executive Summary.

The remuneration structure is, therefore, based on different components and takes the form of the definition of a remuneration package where fixed and variable parts of remuneration are balanced within a broad concept of performance, with targets aimed at generating profit and financial-economic sustainability, together with positive impacts on all stakeholders (shareholders, employees, suppliers, customers, local communities).

A2A's variable remuneration model also aims to enhance and incentivise cohesion and collaboration between people and organizational structures through transversal Key Performance Indicators and by means of a transparent and shared allocation process, also encouraging – with specific targets – inclusion and equal opportunities.

The Policy is reviewed and updated on an annual basis.

Executive Summary

Introduction - Preamble and Regulatory Framework

Section

One - 2025 Remuneration Policy

Focus on Policy for the Emergency Replacement of the General Manager

In 2021, the Board of Directors had entrusted the Remuneration and Appointments Committee with the task of assisting it in preparing, updating and implementing the plan for the succession of Executive Directors – by which is meant the figure of the General Manager – in cases of sudden need and to ensure the long-term sustainability and implementation of the approved multi-year Strategic Plans.

The Remuneration and Appointments Committee has therefore defined – through a specific policy approved in May 2022 by the Board of Directors – the procedure to be followed for the management of the emergency succession of the General Manager for any eventuality of his/ her early termination with respect to the ordinary term of office, namely:

• Resignation;
• Dismissal;
• Death;
• Inability to perform office duties for more than 3 months.

Following policy approval, the Remuneration and Appointments Committee also reviewed and approved the criteria for the selection of candidates (internal managers) constituting the talent pool to be drawn from in case of need.

Specifically, the Committee annually analyses the assessments of several candidates based on the following indicators:

• Evaluation on critical competences for the role and on soft skills;
• 360° feedback indicator;

identifying a limited number of Top Executives in the aforementioned talent pool on which to prepare and implement training initiatives and services that complement the candidates' experiences and profiles, thus making them better prepared in the event that such a procedure needs to be invoked.

People and Transformation, Administration, Finance and Control, Strategy and Growth, Communication, Sustainability and Regional Affairs

Activities pertaining to the Remuneration Policy of the Board of Directors and Key Executives also involve:

• People and Transformation Department for technical-specialist assistance on remuneration issues and for the elaboration of support analyses such as, by way of example but not limited to, monitoring of internal remuneration and market trends; studies and benchmarks of market practices and trends; analysis of remuneration levels in terms of internal equity, with particular attention to gender equality issues, as well as competitiveness with respect to markets selected as reference;
• the Administration, Finance and Control Department for the identification and exploitation of quantitative economic-financial parameters underlying the variable incentive systems and the expost assessment of their level of achievement.
• The Strategy and Growth Department, for the identification and enhancement of objectives related to the Strategic Plan.
• The Communication, Sustainability and Regional Affairs Department, for the definition and enhancement of ESG parameters in close coordination with the ESG Committee and Relations with the Territories.

Board of Statutory Auditors

The Board of Statutory Auditors, with regard to remuneration, attends the meetings of the Remuneration and Appointments Committee and expresses the opinions required by current regulations, verifying consistency with the Remuneration Policy adopted by the Company.

B. Detailed Structure of the Remuneration Policy

The structure of the Policy for the year 2025, described in detail below, reflects the remuneration determinations made by the Shareholders' Meeting in 2023, when the current management and supervisory bodies were appointed, and by the Board of Directors in the three-year period 2023- 2025.

What is set forth in this document, therefore, illustrates the Policy approved by the Board of Directors in office at the date of publication and will be implemented during the 2025 financial year by the new Board of Directors and the competent Delegated Bodies, in compliance with what will be decided by the Shareholders at the Shareholders' Meeting.

B1. Remuneration of the Members of the Board of Directors, excluding the Chair and CEO

The remuneration of the individual Board Directors, not vested with special offices, powers or functions, and of the Vice-Chair consists of:

• the fixed gross annual remuneration, approved by the Shareholders' Meeting upon appointment, received as Member of the Board of Directors and equal to 80,000 euro/year;
• the fixed gross annual remuneration, approved by the Board of Directors, for participation in the Board Committees, is as indicated in the table below. Said remuneration is commensurate with the commitment required and there are therefore different amounts for the Control and Risk Committee, in terms of greater commitment required, and the Chair, in view of the role assigned for work coordination and liaison with the corporate bodies and corporate functions.

Chair of the Board of Directors		330,000 € (including compensation as Director)

For the Directors who are members of professional bodies, the 4% contribution, as required by law, is paid entirely by the Company.

• fixed remuneration for the specific office of Chair for 250,000 euro gross/year, in addition to the amount indicated above.

For the Chair no attendance tokens are provided for individual meetings of the Board Committees; moreover, repayment is provided for any remuneration received for participation, as Director, in the Boards of Directors of investees.

The remuneration of the Chair is completed by the provision of non-monetary benefits provided to the managerial staff of the Group (details provided in paragraph c7).

In addition, considering the academic role held by the Chair of the Board of Directors of A2A prior to taking on his current position, the contributions for pension and social security purposes paid by the University where he is enrolled, shall ultimately be borne by the Company, in accordance with the law.

The remuneration of the Chair described above was approved in 2023 by the Board of Directors considering:

• the remuneration practices of companies with similar characteristics to A2A;
• the executive nature and the strategic importance of the Chair;
• the responsibilities, delegations and powers attributed.

Executive Summary

Introduction - Preamble and Regulatory Framework

Section One - 2025 Remuneration Policy

Sustainability is an integral part of A2A's business strategy and consists of:

• project indicators linked to the Circular Economy, Energy Transition and Corporate strategic drivers deemed most relevant to the organisation's sustainable success;
• accidents reduction: demonstrating the absolute priority of HSE issues and, in particular, the protection of people's safety; risk minimisation and prevention are fundamental aspects of A2A's operations, which is committed to ensuring continuous improvement in workplace safety, transferring this priority also to the assessment of management performance;
• improvement of DE&I (Diversity Equity & Inclusion): indicators: demonstrating the Group's attention to diversity, equity and inclusion issues and, in particular, to gender balance in the corporate population.

Once the Access Gate has been passed, it is required to achieve a minimum of the targets below which the remuneration shall not be paid; upon exceeding said minimum achievement, the remuneration may vary linearly:

• CEO: between 18% and 27% of the fixed component (equal to 200,000 euro) depending on the level of achievement of objectives;
• General Manager: between 24% and 56% of the fixed component (equal to 500,000 euro) depending on the level of achievement of objectives.

The higher percentages indicated above (27% and 56%) represent a maximum amount above which, even in the presence of overperformance of the Company and the CEO-General Manager, no further increase of the amount due shall be provided.

Long-term variable compensation

The long-term variable remuneration, approved by the Board of Directors on 16 March 2023 and 19 October 2023 and by the Shareholders' Meeting on 29 November 2023, also addressed to Key Executives, provides for:

• a 3-year target measurement period (2023-2025) with disbursement, based on the achievement of targets, after the approval of the financial statements as at December 31, 2025 by the Shareholders' Meeting;
• a Gate that requires A2A's rating to be maintained as "Investment Grade" by at least one of the rating agencies and cancels the fee payable if this indicator is not maintained2;
• the targets indicated in the table below.

LTI data sheet 2023-2025
	KPIs	Weight	Minimum	Target	Maximum

Executive Summary

Introduction - Preamble and Regulatory Framework

Section One - 2025 Remuneration Policy

In addition to the Gate, certain targets must be achieved below which the remuneration shall not be paid; upon exceeding said minimum requirement, the remuneration may vary, based on level, between 25% and 46% of the total wage of the General Manager and of the Chief Executive Office:

LTI – CEO and General Manager

Moreover, for the Chief Executive Officer, repayment is provided for any remuneration received for participation, as Director, in the Boards of Directors of investees.

B4. Remuneration of Key Executives

A2A's existing Macro-Organisation provides for a number of 9 positions attributable to Key Executives. Key Executives shall refer to those individuals who, by virtue of the position held in A2A's organisational structure, have, from time to time, the power and responsibility, directly and indirectly, of planning, directing and controlling the activities of the Company and the Group, by undertaking the role of Head in the following corporate functions:

• Head of the Business Unit Circular Economy;
• Head of the Market Business Unit;
• Head of the Generation Business Unit and Trading;
• Head of People and Transformation;
• Head of Digital&Innovation;
• Head of Administration, Finance and Control Department;
• Head of Strategy and Growth;
• Head of Legal Affairs and Compliance;
• Head of Communication, Sustainability and Regional Affairs.

As of the date of this Report, therefore, the definition of "Executives with strategic responsibilities" also includes the nine managers responsible for the functions mentioned above.

For the sake of completeness, it should be noted that, compared to the previous year, the Head of the Smart Infrastructures Business Unit is currently not among the Executives with Strategic Responsibilities. With reference to this function, A2A is in fact in the process of assessing the relevance and strategic weight of the function itself, also taking into account the recent organisational changes that took place in February 2025.

The 2025 remuneration package for Key Executives is composed as follows:

	2025 Remuneration package for strategic executives
Fixed component	• Determined based on the role and responsibilities assigned considering the average salary levels applied to roles of comparable complexity, by national companies comparable in size
	• Determined based on professional specialization and technical, and managerial skills required and held
Short-term variable (MBO)	34% of the annual gross fixed amount at target (average value)
Long-term variable (LTI)	28% of the annual fixed gross target amount (average value), upon reaching 100% of the long term targets (2023-2025), assigned in 2023 by the Board of Directors

Note: the information on the weight of variable components compared to the fixed amount does not include the remuneration package of the Head of the Smart Infrastructures Business Unit, as the evaluation of the strategic nature of the position is ongoing.

With regard to the short-term component, the 2025 Remuneration Policy envisages aligning the MBO system for Executives with the incentive schemes for Non-Executives, introducing the Bonus Pool MBO mechanism, with the aim of meeting the goals described above.

Operation of the MBO Executive Bonus Pool System*

The Target Bonus Pool is determined by the sum of the MBO Targets of the eligible staff within the Pool. Three pools are planned: 1) Top Management (including Key Executives); 2) A2A Group Executives; 3) Unbundling Company Executives.

This value may increase or decrease based on a Correction Factor, calculated on the performance of two economic-financial targets, subject to annual review: Group EBITDA and CAPEX3. The Factor has an incremental or decremental effect on the Bonus Pool, depending on the results achieved. If the Correction Factor is lower than the minimum level, it will also act as an access gate to the system. It is also expected that the Correction Factor may be subject to annual review.

The associated incentive scheme provides:

• Central economic-financial objectives: for Key Executives the associated weight is between 40% and 50%;
• ESG objectives: for Key Executives, the associated weight is at least 25 per cent, leaving the possibility for Key Executives to supplement with additional ESG objectives/ projects with ESG value;
• Individual targets: for Key Executives the associated weight is between 35% and 25%

Sustainability is in fact confirmed as an integral part of A2A's business strategy, and according to the role played by the Strategic Manager, the ESG targets are broken down as follows:

• Environmental:

• Continuation of work on the Climate Transition Plan (CTP). In particular, drafting and publishing a Group CTP to systematise BU information and provide specific decarbonisation actions and targets for the Group, to be integrated with the Strategic Plan;

• Implementation in the Business / Staff Units of the action plan identified in the CTP on the year 2025 (e.g. Carbon Capture Utilisation and Storage technologies on CCGT, Smart GridGas, etc).

• For the Unbundling companies, the economic-financial indicators will refer to the overall perimeter of the Unbundling companies. * For some specific managerial roles, defined and shared with the Remuneration and Appointments Committee, for Compliance / Corporate Governance reasons, the MBO Bonus Pool instrument will not apply, and the traditional MBO will be maintained.

Executive Summary

Introduction - Preamble and Regulatory Framework

Section One - 2025 Remuneration Policy

• • Social:
  • KPIs linked to Accidents are maintained to demonstrate the absolute priority of HSE issues and, in particular, the protection of people's safety, since risk minimisation and prevention are fundamental elements of A2A's operations, which is committed to guaranteeing continuous improvement of safety in the workplace, transferring this priority also to the assessment of management performance;
  • DE&I indicators in terms of increase in the % of women in positions of responsibility, presence of women on Boards in line with the Gulf/Moscow Law, increase in the % of women hired. These KPIs are maintained over time to demonstrate the Group's attention to diversity, equity and inclusion issues and, in particular, to gender balance in the corporate population.

• Governance:

• Training compliance KPIs: demonstrating the focus on compliance and the internal control system, KPIs were introduced linked to the completion of compliance training courses identified as a priority for the Group.
• Adjustment and integration of internal processes (e.g. ERM) related to ESG CSRD reporting. The economic and financial targets will be different from Group Ebitda and Capex in order not to duplicate the effect already acted by the Correction Factor.

Based on the overall achievement percentage, an performance band will be determined to which a maximum payout percentage will correspond. The new MBO system goes beyond the logic of individual achievement percentages, adopting a pool approach: the payout will thus be determined by redistributing the Bonus Pool Target according to performance bands. The achievement percentage corresponding to the bands and the related payout caps may be updated annually.

If the evaluation of the resource's skills, as part of the Performance Management process, is equal to the minimum level, the payout will be reduced by 50%.

During the reporting period, a Mid-Year Review phase is planned, in which it will be possible to reopen the target sheet in the face of extraordinary events such as:

• • events outside the Group, of an exceptional nature and totally unrelated to the scope/ influence of the MBO assignee (e.g. pandemic, war, energy crisis, competitor bankruptcy, regulatory changes, etc.);
• • strategic or priority changes;
• • organisational changes.

Any change in the objectives assigned to the Key Executives will require an authorization step in the Remuneration and Appointments Committee.

Within the reporting process, there is also a phase of analysis of the distribution of the performance bands within which the Chief Executive Officer can modify the performance band (one level more or less). Any changes in the Key Executives band must be validated by the Remuneration and Appointments Committee with subsequent information to the Board of Directors.

B5. Board of Statutory Auditors

The Remuneration Policy provides for a fixed remuneration, approved by the Shareholders' Meeting, commensurate with the responsibilities, complexity and onerousness of the assignment.

On April 28, 2023, the Shareholders' Meeting determined, for the period of office of the Board of Statutory Auditors, the following gross annual remuneration:

• 130,000 euro for the Chair of the Board of Statutory Auditors;
• 80,000 euro for Statutory Auditors.

For the Statutory Auditors who are members of professional bodies, the 4% contribution, as required by law, is paid entirely by the Company.

Executive Summary

Introduction - Preamble and Regulatory Framework

Section One - 2025 Remuneration Policy

B5. Non-monetary benefits

With the aim of ensuring that the overall remuneration offered is as competitive as possible and in line with the best practices adopted at national level, the total remuneration of Directors, the General Manager and Key Executives is supplemented by non-monetary benefits.

The Directors, excluding the Chair and Chief Executive Officer, and the members of the Board of Statutory Auditors (including the Chair) shall receive as non-monetary benefits:

• insurance policy for occupational and nonoccupational injuries;
• insurance for civil liability (Directors, Auditors and Executives).

The Chair, Chief Executive Officer, General Manager and Key Executives will receive nonmonetary benefits such as:

• insurance policies (occupational and nonoccupational injury; permanent disability due to illness and life);
• supplementary health coverage;
• insurance for civil liability (Directors, Auditors and Executives);
• car for mixed use with a full electric engine, card for recharging on the road and contribution on wall-box and home recharge;
• meal vouchers / canteen

In addition to the above non-monetary benefits, a house allowance in line with the market standards of companies comparable with the Company is attributable for specific needs.

For the General Manager and the Strategic Managers, the same welfare treatments adopted for all Group Managers (e.g. company conventions, A2A Life Caring, etc.) are also made available / usable.

B6. Indemnities in the event of termination of office or termination of employment

For the Chief Executive Officer-General Manager, considering that the subordinate employment relationship of the General Manager and the position of Chief Executive Officer are, by the nature of the activity involved in the job with respect to that of the office, connected, complementary and inseparable, an agreement is in place for the termination of both the administrative and managerial relationship, which provides the payment of an amount equal to the sum of the indemnity in lieu of notice and the maximum additional indemnity provided for by the National Collective Labour Agreement, in relation to the case of termination of the employment relationship4.

This remuneration is due if the relationship is terminated by the Company for reasons other than just cause or by the Chief Executive Officer-General Manager for resignation for just cause due to events that have caused actual and concrete demotion, or due to organisational changes within the Company that have caused a reduction in duties (including the revocation or non-renewal of the office of Chief Executive Officer in the absence of just cause).

As far as the Chair of the Board of Directors, the Directors and the Key Executives are concerned, there are no specific agreements that regulate ex ante the economic aspects relating to the termination of office or termination of employment.

The termination of the employment relationship with Key Executives normally occurs (i) by resignations submitted by Key Executives, (ii) following an agreement reached by mutual consent between the Company and the Key Executives or (iii) by unilateral initiative of A2A.

^4. This amount will be calculated, with regard to the fixed part, on the basis of the Fixed Remuneration actually received at the time of termination of the employment relationship; with regard to the variable part, on the basis of the average remuneration actually received or accrued in the last three years as Variable Remuneration. Should the termination take place before the end of the third year, as better remuneration, reference shall be made to the better remuneration comprised between 60% of the amount of the Variable Remuneration - as determined above - and the Variable Remuneration actually received in the previous year (if the relationship has lasted less than two years) or the average Variable Remuneration actually received in the previous two years.

In case of termination as a result of resignations submitted by Key Executives, as well as in case of early termination of employment by A2A's one-sided decision, the respective severance indemnity shall apply as provided by law and by the National Collective Labour Agreement (CCNL) for Executives of companies members of the Confservizi associations; therefore, the overall individual severance indemnity, excluding the indemnity paid in lieu of notice, may reach a maximum of 24 months' pay calculated on the basis of the criteria of article 2121 of the Italian Civil Code.

Furthermore, beginning in 2022, the Company may apply non-competition and non-solicitation agreements ("PNC") to be implemented in favour of certain executives, including the General Manager with the following, alternative logics:

• disbursement, during the employment relationship, of an amount up to 100% of a global annual salary (excluding any LTI component where applicable) in a single payment; or
• disbursement of an option (approximately 20% of the GAS for each year) that gives A2A the right to enter into a non-competition and nonsolicitation agreement on terms and conditions already provided for (amount up to 100% of total remuneration); or
• disbursement, upon termination of employment, of an amount up to 100% of total pay with quarterly payment;

for a commitment not to carry out activities in competition with the Group during the 12 months following termination of the employment relationship, with a limitation to the Italian territory.

As of the date of this Report, 9 non-competition and non-solicitation agreements in the form of options are in place in favour of the Key Executives.

If the Key Executive signed a Non-compete Agreement, in the event of resignations submitted by the Key Executive and unless otherwise provided in the Non-compete Agreement, the Company shall exercise the aforementioned option within the terms provided for, and then, if necessary, forego said option by the expiry of the Non-compete Agreement, in the event of the subsequent stipulation of

agreements aimed at regulating, in a specific and overall manner, the termination of the Key Executive.

In the event of resignations submitted by the Key Executive, if A2A and the Key Executive should sign a private deed in order to regulate the conditions of exit, this private deed in order to govern the clauses usually envisaged in these types of agreements and in particular, (i) non-solicitation obligations, (ii ) waiver by Key Executive, following the agreement reached having an innovative and transactional nature, of any and all claims against the Company and the Group, in respect of waivers of liability for the role and offices held, (iii) waiver of the option (Non-compete Agreement), (iv) the Key Executive has been granted any contributions, including monetary contributions (of amounts ordinarily applied in previous employment terminations following resignations) to take account of the waivers, any expenses actually incurred by Key Executive, as well as any charges related to the advance notice, provided that the overall value of the whole is less than the narrow threshold envisaged by the A2A Procedures for Transactions with Related Parties, and (v) at the request of the Key Executive, commitments to transfer the company car to the person indicated by the Key Executive and the transfer of company devices at book value.

The application of the above, in the event of termination in the year 2025, would result in:

• for the Chief Executive Officer-General Manager, the payment of an amount equal to 14 months total and inclusive of the notice period of remuneration calculated according to the contractual rules;
• for Key Executives, the payment of an amount depending on individual seniority calculated according to the criteria of Article 2121 of the Civil Code (minimum 10 and maximum 36).

B7. Deferral of cash components and claw-back and malus clauses

With regard to the variable component of remuneration, claw-back clauses are provided for, within the time limits established by the laws in force and regardless of the termination of the employment relationship, which allow the Company to take steps to return all or part of the variable components of remuneration (or not to pay them, also withholding, in the context of malus clauses, the components subject to deferment).

Executive Summary

Introduction - Preamble and Regulatory Framework

Section One - 2025 Remuneration Policy

These controls are put in place if it is ascertained that the sums allocated have been determined on the basis of targets whose achievement is attributable to wilful or grossly negligent conduct or, in any case, carried out in violation of the reference standards (corporate, legal, contractual) or have been achieved on the basis of data that subsequently turned out to be manifestly incorrect.

A2A also reserves the right not to proceed with any disbursement in respect of individuals who have carried out conduct in breach of company regulations (with particular regard to the Code of Ethics, the Organization Model pursuant to Legislative Decree 231/01 and the Anti-Corruption Model), contractual or legal, or of malicious or seriously negligent conduct committed to the detriment of the Company.

The application of these ex post mechanisms is in any case without prejudice to any other action or remedy permitted by law to protect the interests of the Company.

Therefore, from 2021, the A2A Policy envisages ex-post correction mechanisms in the form of claw-back clauses, which allow the Company to ask for the restitution - or rather not to make payments in the context of malus clauses - of all or part and within three years from bonus payout, of the variable components of remuneration paid to individuals who, with wilful misconduct or gross negligence, have altered the data used to achieve the targets or have behaved in breach of corporate, contractual or legal regulations.

Malus and claw-back clauses are applicable to both the short-term and long-term variable component.

To date, there are no mechanisms for deferment in the payment of the fixed or variable component. Considering the size of the long-term variable remuneration, as well as the structure envisaged for the latter (closed plan with a three-year vesting period and payment only after the approval of the financial statements for the year 2025), the Company did not deem it necessary to include a deferral mechanism.

Exceptions to the Remuneration Policy

Exceptionally and in a non-recurring manner, pursuant to paragraph 3-bis of article 123 ter of the TUF updated in 2019 and by article 84-quater of the Issuers Regulation updated in 2020, the Board of Directors of A2A, subject to compliance with the procedural conditions under which the waiver may be applied and limited to the individual elements of the Policy set out below, on the proposal of the Remuneration and Appointments Committee, subject to the prior favourable opinion of the Related Parties Committee and having consulted the Board of Statutory Auditors, may waive the contents of the Policy illustrated in this Report. The sole purpose of this provision is to guarantee the pursuit of the long-term interests and sustainability of the Group as a whole, to ensure the Company's ability to compete in the market.

Exceptional circumstances taken into account may include the following:

• extraordinary transactions (e.g. restructuring, reorganisation or reconversion) and changes to the Group's organisational, management and administrative structure that were not foreseeable and consequently not planned in the definition of the 2024-2035 Strategic Plan;
• exogenous shocks (including those of a regulatory/normative nature) of an unforeseeable and extraordinary magnitude, such as to impact on the economic-financial results and value creation in the long term with economic effects - on the Group's net profit in excess of 10%;
• repeals or substantial scheduled date changes of the 2024-2035 Strategic Plan;
• the need to recruit due to unforeseen events - managers from the labour market using instruments to compensate for other variable remuneration already accrued by the manager at his or her previous workplace, but which cannot be achieved or recovered.

In the presence of such exceptional circumstances, the Company therefore reserves the right to temporarily derogate from the Policy most recently approved by the Shareholders' Meeting on the following elements:

• variable incentive programs;
• one-off monetary bonuses and allocation of certain benefit allowances, exclusively within a logic of attraction/retention of key employees.

These exceptions, aimed at protecting the exclusive interest of the Company, may act on the above-mentioned elements of the remuneration policy either for the better or for the worse, in the presence of the abovementioned exceptional circumstances. If the clause is applied, the Remuneration and Appointments Committee, in accordance with the procedure envisaged for transactions with related parties and with the possible support of the People and Transformation

Department and the Administration, Finance and Control Department, will assess any impact on the Policy in order to submit, subject to the favourable opinion of the Related Parties Committee and having consulted the Board of Statutory Auditors, for approval by the Board of Directors any proposal to amend and waive the Policy, provided that it is consistent with the philosophy and principles of the same expressly referred to herein. Approval of such a waiver by the Board requires abstention from the BoD debate and related resolutions by any interested parties.

All detailed information on the possible application of waivers to this Remuneration Policy will be reported in the Second Section of the Report on Remuneration Policy and Remuneration Paid for the year following the application of the waiver.

• gross fixed remuneration, approved by the Shareholders' Meeting, received as Board member and equal to 80,000 euro/year, prorated for the period of office in 2023;
• a fixed gross amount, approved by the Board of Directors, for participation in the Board Committees, according to the scheme above, pro-rata for the term of office.

In addition to the previous amounts, in accordance with the resolution of the Board of Directors, the Chair was granted remuneration of 250,000 euro/year for the specific office assigned.

Considering the academic role held by the Chairman of the Board of Directors of A2A prior to undertaking his current position, pension and social security contributions paid by the university where he is enrolled, pursuant to the law, ultimately remain the responsibility of the Company.

Moreover, in line with what is indicated in the 2024 Remuneration Report, the Vice-Chair of the Board of Directors Giovanni Comboni was paid, in addition to the remuneration received as Director, a gross annual remuneration of 60,000 euro5 for his responsibility for "Internal Audits".

In accordance with the Articles of Association of A2A, members of the Board of Directors were paid an amount equal to the reimbursement of expenses actually incurred by virtue of their office.

For the Directors who are members of professional bodies, the 4% contribution, as required by law, was paid entirely by the Company.

The annexed table (1a) also indicates, for Directors, including the Chair, the value of nonmonetary benefits recognized.

A3 Members of the Board of Statutory Auditors

Members of the Board of Statutory Auditors were paid the following remuneration, approved by the Shareholders' Meeting of April 28, 2023.

In particular, the following were paid:

• to the Chair, a fixed gross remuneration of 130,000 euro/year;

For Statutory Auditors who are members of professional bodies, the 4% contribution, as required by law, was paid entirely by the Company.

A4 Chief Executive Officer

In 2024, the following amounts were paid to the Chief Executive Officer:

• a fixed gross remuneration, approved by the Shareholders' Meeting, received as Board Member and equal to 80,000 euro/year;
• fixed gross remuneration, approved by the Board of Directors for the specific office assigned, amounting to 120,000 euro/year.

As stated in the 2024 Remuneration Report, variable annual remuneration included:

• for the entire population assigned variable incentives, including the Chief Executive Officer, an "access gate", based on EBITDA of the Company in 2024 and Capex at 12/31/2024, that reduced by 30% or annulled the remuneration payable in the event of the Group's economic and financial performance being lower than the minimum level envisaged for the reference year;

^5. The amount paid in 2024 is a total of €53,808 as indicated in Table 1/a "Compensation to the Board of Directors" as the compensation was increased from €40,000 to €60,000 on 24 April 2024.

• for the Chief Executive Officer, two targets:
  • Industrial Cash Flow, set as target on the budget value for the reference year and with +/-5% fluctuation;
  • Net Debt/Ebitda, set, as target, at 2.6x with a range of 2.7x (corresponding to the minimum achievement of the target) and 2.5x (corresponding to the maximum achievement of the target)6.

Following the introduction of the LTI, the target variable remuneration of the CEO was reduced from 66,667 euro to 45,000 euro.

For the Chief Executive Officer, as described in the 2024 Remuneration Report, in addition to the "access gate", it was also necessary to achieve a minimum level of the targets below which the remuneration could not be paid; upon exceeding said level, the remuneration could vary linearly

between 18% and 27% of the total fixed emolument (200,000 euro) depending on the extent to which targets are achieved. The 27% of the overall emolument (54,000 euro) represents a maximum amount ("Cap") above which, even in the presence of over-performance of the Company and the CEO, no further increase of the amount due shall be provided.

At the beginning of 2025, the Board of Directors, with the support of the Remuneration and Appointments Committee, verified and certified the level of achievement of the aforementioned targets by calculating the resulting overall % achievement (equal to 120.0%), against which variable remuneration was paid to the Chief Executive Officer equal to 54,000 euro, as illustrated in the following table showing the performance targets achieved compared to those expected:

Indicator description	Weight	Performance scale				Achievement
		Minimum	Target Maximum		Actual	Achievement %	Pay-Out

Net Debt / Ebitda (2024 budget)	50%	2.7	2.6	2.5	2.2	120%	27,000

A5 General Manager

As stated in the 2024 Remuneration Report, variable annual remuneration included:

• for the entire population assigned variable incentives, including the General Manager, an "access gate", based on EBITDA of the Company in 2024 and Capex at 12/31/2024, which reduced by 30% or annulled the remuneration payable if the Group's economic-financial performance is not in line with the budget of the year of reference;

• for the General Manager, the following goals:

• Ebitda (weight 20%), set as target on the budget value for the reference year and with +/-7.5% fluctuation;
• Capex (weight 20%), set as maximum (120%) on the budget value, as minimum on 85% of the budget value and as target (100%) on the linear interpolation between minimum and maximum⁷ ;
