STRATEGIC PLAN 2025-2028

Pieve di Soligo – 13 February 2025

6. Annex

The Ascopiave Group, listed on the STAR segment of the Italian Stock, is a solid, reliable and transparent counterpart for its stakeholders

The plan envisages a growth path that will increase the company's profitability, while maintaining a balanced financial structure and a profitable dividend distribution

Strategic pillars

The Ascopiave Group's strategy is based on four fundamental pillars and aims to achieve a sustainable business profitability, by developing the resources and skills needed to capture trends effectively in the reference markets

Ascopiave's positioning and expertise represent a solid foundation to support growth in its core business (gas distribution)

Innovation management is a crucial activity for Ascopiave and targets both short and medium-long term goals

By anticipating market dynamics, Ascopiave can leverage on its expertise to diversify its business perimeter (electricity generation from renewable sources, «green» gases, other infrastructural industries)

Improving economic and operational efficiency is at the heart of Ascopiave's management policies

Acquisition of gas distribution's assets from A2A Group (1/2)

In December 2024, Ascopiave signed a preliminary purchase agreement to acquire a significant compendium of gas distribution assets from A2A Group

Deal's timeline

The growth of the core business of gas distribution outlined in the plan has its concrete premises in the transaction that will be finalized during 2025 with the A2A Group for the acquisition of 100% of the shares of a corporate vehicle (Newco A2A Assets) that will hold, at closing, a going concern comprising a portfolio of assets in the Lombardy region. The preliminary purchase agreement (signing) was signed in December 2024 and the closing is expected in July 2025. Current

Transaction's purpose

The deal will allow Ascopiave to significantly increase its user base (+56%) and strengthen its territorial presence in Northern Italy, becoming the 2°/ 3°operator at national level² .

Sustainability goals

The «Sustainable Development Goals» identified by Ascopiave through dialogue with its stakeholders represent the elements on which the Group will base its sustainable growth path

The key principles on which the «Guidelines for the Pursuit of Sustainable Success», adopted by the Board of Directors of Ascopiave in 2022 and revised in December 2024, are aligned with the Group's Values reported in the Code of Ethics. This integrated approach allows to embrace effectively the targets included in the Sustainable Development Goals (SDGs) set out in the United Nations' 2030 Agenda.

The sustainability path undertaken by the Ascopiave Group is inspired by the Sustainable Development Goals (SDGs) related on one hand to its business activities (SDGs 6, 7, 8 and 9) and on the other hand to the impact and effects that the Group have on the territories in which it operates (SDGs 10, 11, 12 and 13).

In this context, Ascopiave's strategy incorporates the concept of assuming responsibility that the 2030 Agenda requires to every corporate, not only in terms of what it carries out at the business level, but also as an activator of changes with a view to creating sustainable systems both locally and globally.

• Policy for managing dialogue with all shareholders and other stakeholders: approved by the Board of Directors in December 2021, the document regulates the management of dialogue with shareholders, in line with the Corporate Governance Code and the engagement policies of institutional investors.
• Remuneration policy: in the new three-year incentive plan for 2024-2026, variable incentive mechanisms linked to the Group's sustainability goals have been introduced, tied to the achievement of the CO² reduction target set out in the 2024-2027 Strategic Plan.
• Internal control and risk management system: it includes rules, procedures, and structures to identify, measure, manage, and monitor the main risks, contributing to the company's sustainable success. The Board of Directors approved the Enterprise Risk Management Policy in February 2024 to operationally implement this system. The «Risk Model», evaluated and updated semi-annually, includes, among other things, Legal & Compliance risks and CSR¹and ESG issues.
• Sustainability Committee: established in November 2021, the Sustainability Committee has investigative, propositional, and consultative functions regarding environmental sustainability and energy transition. It proposes the «Guidelines for the Pursuit of Sustainable Success» to the Board of Directors and supports the Control and Risk Committee (CRC) in evaluating periodic reporting. Additionally, it coordinates with the CRC in the development of annual and multi-year sustainability goals, with particular attention to risk management.

3. Context and market trends

Ascopiave Group – Strategic plan 2025-2028 23

According to ISTAT, Italy's GDP has grown by 0.5% in 2024 and is expected to grow by 0.8% in 2025¹

Current situation in Italy²

Market outlook²

In 2024, inflation has stood at 1.0% with a significant decline compared to +5.7% of 2023. In 2025, the Italian government estimates an inflation of 1.8%² .

• ✓ Short-term and long-term interest rates are expected to converge respectively to 2.7% and 4.9% in 2033, while inflation is expected to reach 2.4% in 2033.
• ✓ The unemployment rate is expected to decline continuously, from 7.0% in 2024 to 6.4% in 2029, in a context of moderate economic growth and employment dynamism.

✓ Total expenditures in 2023 increased by 4.4% compared to the previous year. This trend is mainly due to the dynamic of the capital expenditure sustained (+19.2%), both for the public investment component, favoured by the development of expenditure on projects financed by the PNRR, and for the investment contributions,

Outlook on investment and credit²

affected by building bonuses. The result is a ratio of gross fixed capital expenditure to GDP of 3.2% in 2023 and is expected to be 3.4% in 2024. For the following years, the ratio is expected to be 3.5% in 2025, 3.6% in 2026 and 3.4% in 2027.

European and italian decarbonization goals

Both the European Union and Italy have based their growth targets for the next decade on the transition to a sustainable economy model

With the aim of facing the challenges of climate change, the European Union has created the European Green Deal, which is a pact between countries that aims to achieve «carbon neutrality» by 2050. For this purpose, the EU has allocated nearly 660b€ in the 2021-2027 budget, creating numerous support tools to facilitate the energy transition.

With the PNRR's revision, the Government has increased the plan amount from approximately 191 bln€ to around 194 bln€, raising the share allocated to the energy transition from 37.5% to 39% thanks to the development of various initiatives, including those related to «green» gases, energy efficiency, circular economy, and renewable sources.

In the last two years, gas supplies in Europe have been characterized by increasing volatility, which is expected to remain in the future.

The volatility is mainly due to i) the reduction of Russian gas imports into Europe;

(ii) the consequent greater role of liquefied natural gas imports in meeting European demand.

A solution proposed by the European Commission to reduce the European Union's energy dependence on Russian gas supplies is the RePower EU plan, which is part of the EU's initiatives to support the energy transition.

The progressive adoption of green energy carriers (biomethane, green hydrogen, bioliquids) will have to ensure the replacement of fossil fuels with zero-emission alternatives.

The new infrastructural network

The gas network will require technological and infrastructural adjustments to facilitate the introduction and transport of «green» gases to decarbonize the system

Dynamics of the gas distribution sector in Italy

Gas distribution in Italy is a mature and established sector that needs to renew itself to respond to the challenges arising from the energy system's evolution

The gas distribution sector has registered a progressive consolidation of supply.

The scenario of energy system's transformation will require a change in the sector, in terms of:

• ✓ technological and industrial renewal;
• ✓ rethinking the management logic of activities.

The regulation of ATEM tenders (1/2)

The tenders for awarding the ATEM's gas distribution service are regulated by national legislation and regulation, which are subject to consecutive improvements

Over the last 20 years, the natural gas sector has been affected by profound changes, which have also affected the methodologies and targets of tariff regulation, as well as the methods for identifying the operators of natural gas distribution systems.

• ➢ Legislative Decree 164/2000 ("Letta Decree") established the principle that the service must be entrusted with public tender (competition for the market)
• ➢ Several and subsequent interventions have defined the liberalization process in greater detail:
  • ✓ Identification of 177 ATEM (subsequently reduced to 171) for the award of concessions ¹
  • ✓ Definition of the criteria for the evaluation of tenders (DM 226/2011 and ss.mm.ii.): economic offer, investments plan, safety standards and quality of service.

Regulatory framework Implementation status

Following the adoption of the ministerial decrees, tenders' organization encountered numerous implementing obstacles, which delayed the tenders' start.

• ➢ At the end of 2024, the procedures for entrusting 10 areas were completed (Milan 1, Turin 1, Turin 2, Belluno, Valle d'Aosta, Udine 2, Naples 1, La Spezia, Rimini, Catanzaro-Crotone).
• ➢ There are 9 licenses (Milan 1, Turin 1, Turin 2, Belluno, Valle d'Aosta, Udine 2, Naples 1, La Spezia, Rimini)

The regulation of ATEM tenders (2/2)

Some relevant measures have recently been adopted (or are in the process of being adopted) to simplify and accelerate the process of publishing tender notices and to update the criteria for evaluating bids

Simplification of ARERA verifications ➢ During 2024, ARERA approved the «Integrated text of the provisions on the framework tenders for the distribution of natural gas». ➢ The main purpose of this document is to reunite and simplify in a single procedure the two previous separate procedures relating to observations on reimbursement values and observations on tender documents prepared by contracting stations. ➢ In addition, it has introduced simplified provisions to speed up and streamline procedures for verifying VIR-RAB deviations, including in ongoing proceedings; ➢ Similarly, access to the simplified verification system for invitations to tender shall be subject to the adoption of the standard invitation to tender, the standard specification and the standard service contract. ➢ Document published: ✓ Resolution 296/2024/R/gas ➢ Law No. 118 of August 5, 2022 (Article 6, paragraph 1, letter b) provides that if a local authority or a network asset company intends to sell the networks and distribution and metering plants it owns during the tenders for awarding the natural gas distribution service, said networks and plants are valued according to the residual industrial value calculated based on the "Guidelines on criteria and application methods for the evaluation of the reimbursement value of natural gas distribution plants" of 7 April 2014, approved by the decree of the Minister of Economic Development on 22 May 2014. Updating Ministerial Decree 226/2011 (tender criteria) ➢ The MASE¹ , implementing Law No. 118/2022, aims to update DM² 12/11/2011 No. 226, «Regulation for the tender criteria and for the evaluation of bids for the awarding of the natural gas distribution service» and subsequent amendments. To this end, it has initiated a consultation with ARERA, AGCM, and industry associations (the socalled "Cabina di regia"). ➢ The future decree aims to: ✓ mitigate significant issues related to the existence of information asymmetries in the trilateral relationship between outgoing operator, local authorities, and incoming operator; ✓ introduce important elements of coordination between the criteria for valuing interventions and the targets of optimization and rationalization in the use of energy resources; ✓ introduce a significant update of the technological innovation criteria, with an effort to find the right balance between the need to implement a forward-looking vision and the need to remain anchored to parameters of immediate feasibility as well as economic and financial sustainability. Disposal of networks owned by local authorities

Dynamics of gas and energy prices

Pandemic and geo-political crises have accelerated the path of energy transition while introducing a gradient of uncertainty

Gas and electricity prices have been characterized by significant volatility in recent years.

Considering the average annual gas prices at PSV, after the gas price shock of 2022 with an average annual price of 122 €/MWh, in 2023 the gas price has decreased with an average annual price of 42 €/MWh, a value lower also than 2021 average (46 €/MWh). The reduction, compared to the extreme prices of 2022, has continued also in 2024, with an average price of 36 €/MWh.

A similar trend was also observed in electricity prices (PUN): if the maximum average price level was reached in 2022, with an annual average PUN of 303 €/MWh, in 2023 the electricity price has decreased to 127 €/MWh, above the 2021 levels of 125 €/MWh. The reduction, compared to the extreme prices of 2022, has continued also in 2024 with an average price of 108 €/MWh.

Dynamics of the renewable energy sector in Italy (1/4)

European policies have introduced increasingly challenging decarbonization targets and the national energetic policies have followed the EU initiatives' drive

The update of the National Integrated Energy and Climate Plan (PNIEC): based on the European regulatory framework (i.e. the Fitfor-55 and RepowerEU legislative packages), it sets out a series of national targets for 2030 in both energy and climate matters. On the renewable energy front, it sets a target of 39.4% on the total gross final consumption of energy in the country, as differentiated between the different sectors:

• electricity sector: 63.4% is the target of coverage by RES of electricity consumption;
• thermal sector: 35.9% is the RES target for heating and cooling consumption;
• transport sector: 34.2% is the RES target for transport consumption.

Renewable Energy Directive: states that the share of renewable energy in the European Union's gross final energy consumption in 2030 is at least 38.7%¹ .

Dynamics of the renewable energy sector in Italy (2/4)

Renewable energy sector in Italy has shown substantial growth over the past 10 years, with a total installed capacity of ~ 70GW

However, in order to achieve the national decarbonization targets at 2030, it will be necessary to install in Italy about +60GW of new RES capacity not only by stimulating new production, but also by preserving the existing one and, where possible, increasing it by promoting the revamping and repowering of plants which are potentially still competitive.

Dynamics of the renewable energy sector in Italy (3/4)

In 2023 it has been recorded a production from renewable sources of about 117 TWh (increase of approximately +16% vs 2022)

There is therefore a marked change in the production of electrical energy³ : traditional thermal sources have decreased from 84% share in 2005 to 56% in 2023, while RES have increased from about 16% to 44% over the same period.

Strategic pillars Plan projections Shareholder remuneration

Ascopiave's current positioning and expertise in gas distribution provide a solid foundation to support the growth of the managed activities' perimeter in a consolidating sector

Growth strategy – gas distribution

External growth in the core business of gas distribution considered in the financial projections includes only the acquisition of assets from the A2A Group

Growth strategy through M&A – gas

distribution (1/2)

Ascopiave Group – Strategic plan 2025-2028 42

Growth strategy through M&A – gas distribution (2/2)

The acquisition of the gas distribution assets from the A2A Group will allow the Group to strenghten its territorial presence in the Lombardy region

The Group intends to consolidate its position within the sector through the participation in future tenders for service contracts and the establishment of partnerships

The Group has identified several ATEM tenders in which it intends to compete, defining their level of priority and interest.

The tender participation strategy identifies Northern Italy as the geographical focus.

Its implementation depends on the publication's timing and the tender notices.

Available experiences suggest that the timeframes for awarding the service may be quite long, also due to the legal disputes that generally accompany the awarding decisions.

Ascopiave is considering the possibility of establishing partnerships to participate in ATEM tenders or to seize new opportunities in the M&A field

Through partnerships, the Group seeks to increase its competitive chances and diversify financial and operational risks by participating in the results of a broader portfolio of concessions.

Given the complexity of the underlying evaluations also due to their uncertainty and transformative nature - the plan does not provide any estimate of the possible economic and financial impacts of such additional growth options.

Diversification strategy – renewable energies and green hydrogen (1/2)

The Ascopiave Group intends to diversify its activities by growing in the renewable energy and green hydrogen sector, where it is already active and where it is developing some reasonable initiatives

Diversification strategy – renewable energies and green hydrogen (2/2)

The economic and financial projections foresee the completion of ongoing projects for the construction of photovoltaic plants and a green hydrogen production and distribution plant

Ascopiave Group – Strategic plan 2025-2028 46

Ascopiave is developing an integrated project along the entire green hydrogen supply chain, starting from its «production» with the use of electricity from photovoltaic systems

Potential areas and sectors of development

Based on the evolving market environment, regulatory framework and technological advancement, additional areas and sectors of development have been identified

SYNTHETIC GAS and HYDROGEN

Development of pilot projects for the production and injection into the network of synthetic gas produced from emissions captured through carbon capture and storage technologies (CCS).

Implementation of additional projects for the use of hydrogen in distribution networks, as well as investments remunerated or incentivized for this purpose.

OTHER NETWORK SERVICES

Entry into other businesses related to the management of network/infrastructure services:

• electricity distribution,
• water service,
• other services.

This will allow the Group to leverage its expertise and achieve synergies.

The assessment of the investment in these sectors will take into account the potential synergies with the Group current activities, considering the specific operational risk profile and the financial sustainability

Improving operational and economic efficiency is at the core of Ascopiave's management policies, which aims to build on the excellent results achieved in recent years

Corporate policies and practices supporting efficiency

• ➢ Continuous monitoring of process efficiency through operational systems and dedicated organizational resources
• ➢ Incentive-based remuneration for personnel, based on economic and managerial efficiency indicators

Interventions on areas and tools subject to potential improvement

• ➢ Innovative technological solutions/digitalization
• ➢ Streamlining of internal organizational processes
• ➢ Optimized management of existing relationships with external suppliers

Plan

targets

✓ Reduction of general and industrial cost incidence

✓ Maintenance of a lean and flexible cost structure

Innovation

Ascopiave has achieved significant results in managerial efficiency by implementing organizational and technological solutions tailored to this goal and will continue its commitment in this direction

Beginning in 2016, the Group has initiated a reorganization process of distribution activities which has led to:

• renewal and reengineering of systems and procedures;
• rationalization of operational and logistical locations across the territory;
• centralized and integrated management of all major processes;
• adoption of new state-of-the-art information systems for workforce management and distribution business services.

This has enabled optimization in the use of resources, allowing many activities contracted to third parties to be internalized in order to reduce operating costs and increase the possibility of making investments.

Reorganization of activities Post acquisition integration and corporate semplification

• Ascopiave has a solid experience in integrating companies postacquisition, achieving management improvements with costs reductions and increased service quality.

Ascopiave Group – Strategic plan 2025-2028 56

Economic and financial targets

The plan projections have been formulated and defined, taking into account the ongoing and realistically achievable growth and diversification initiatives

Reasonable forecasts

• The projections reflect reasonably achievable goals for the Group.

Growth driven by the regulated gas distribution core business

• The growth in capital invested in the core business of gas distribution is due to the acquisition of assets from the A2A Group (which is expected to be completed in July 2025) and to the execution of a significant capital expenditure plan on the plants currently managed. Capex in the renewable energy and green hydrogen segment relate to the completion of ongoing projects.
• No further development initiatives are reflected in the projections.

Uncertainty about the start of ATEM tenders

Due to the uncertainty about the timing of the launch and awarding of ATEM tenders, no scenario has been developed to quantify the potential effects of their allocation.

Group capex

The plan includes the implementation of a significant amount of capex, which leads to an increase in invested capital in the relevant sectors both organically and through external growth

Capex in gas distribution related to:

• current network's maintenance and development and related measurement infrastructure;
• acquisition of assets from the A2A Group and subsequent development and maintenance of the acquired network;
• efficiency & innovation.

Capex in renewable energy and green hydrogen related to:

• development of new photovoltaic plants;
• development of a project for the production and distribution of green hydrogen.

Capex in new corporate headquarters and other centralized capex.

Divestments in non-fully consolidated subsidiaries (EstEnergy / Hera Comm): Exercise of put options

Insight: capex in gas distribution

Most of the planned investments are focused on gas distribution, following the acquisition of assets from the A2A Group and upgrades to the distribution network within the current perimeter

Network and facilities maintenance:
