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.

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 2nd/ 3rd operator at national level(*) .

(*) The ranking takes into account the Italgas/2iReteGas acquisition; (**) 2024 actual data.

The transaction will be financed through the divestment of the minority interest in EstEnergy and, for the remaining part, through bank financing

(*) Enterprise Value at Closing = Price base (430 m€) + price adjustment estimated by Ascopiave (30 m€); (**) Centralized RAB is included (A2A assets: 22 m€; Total: 62 m€); (***) 2024 actual data.

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

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.

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

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

Based on the evolving of the market environment, the regulatory framework and the 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:

• 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

• ✓ Reduction of general and industrial cost incidence
• ✓ Maintenance of a lean and flexible cost structure

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 post-acquisition, achieving management improvements with costs reductions and increased service quality.
• Since January 2025, the Group's company structure has been rationalized with the unification of the companies operating in distribution in two legal entities, each with a defined territorial presence, in order to further streamline processes and achieve consequential organizational and management synergies.

A2A Assets' integration

• The integration of A2A assets will further improve the Group's economic efficiency standards, thanks also to the complementarity of the new acquisitions with the current Ascopiave Group's organization.
• Ascopiave and A2A are collaborating in the pre-closing phase to guarantee the best starting conditions for the activities of the Newco receiving the assets, with the aim of working from the beginning with the systems and organizational modalities adopted by the Ascopiave Group and of enhancing the skills and professionalism of Newco's human resources.

Ascopiave Group – 11th ITALIAN CEO CONFERENCE – 18 46 th June 2025

Ascopiave plans to increase its operational and economic efficiency through the digitalization of networks and metering infrastructure

SMART METERS INSTALLATION NETWORK DIGITALIZATION

• The Ascopiave Group was among the first companies to experiment with the installation of mass market smart meters.
• The installation activity of smart meters is almost entirely internalized, in compliance with the targets set by the Authority and with the aim of planning these interventions in the most appropriate way.
• Identifying the right mix between Radio Frequency and P2P(*) meters, and the economies of scale generated by covering large areas of territory, allows for significant optimization of operating costs.

• The Group aims to install sensors capable of detecting, recording, transmitting, and executing commands, creating a digital twin of the physical infrastructure in order to:
  • ➢ optimize network monitoring in terms of pressure and odorization;
  • ➢ acquire real-time data and simulate plant conditions;
  • ➢ adapt the network for the injection of biomethane and, in the future, other «green» gases.

Ascopiave plans to increase its operating and economic efficiency through the digitalization of processes

• The Ascopiave Group has developed a remote site management system that allows for the monitoring, verification, and validation of site activities assigned to external companies. This application enables the client and the executing company to interact in real-time, optimizing the control and validation activities of works.
• The system facilitates the verification phase of the works by using image recognition techniques supported by AI.
• The Group plans to develop a new remote command and control platform to manage IoT devices that enable the digitalization of gas networks.
• This digitalization will allow for complete remote management of the main processes and facilities of the network, improving efficiency, flexibility, and facilitating the management of renewable gases and the reduction of emissions.
• The Group is creating a predictive maintenance system, based on Machine Learning and AI algorithms, which, using the data of the innovative Picarro technology, is able to identify critical network segments based on the analysis of fugitive emissions and detected leakages.
• The goal is to anticipate extraordinary maintenance on the most critical network segments, thereby optimizing investment management, improving overall safety, and reducing methane gas emissions.

Staff training: target of 29 hours/year of training per employee by enriching the e-learning training offer available to Group employees, and by further implementing a dedicated training platform.

Average age: the Group intends to maintain the current average age of about 47 years, ensuring uniformity in the distribution of the different employee age groups.

Welfare: further expansion of the services available on the platform, ranging from education and training, social security and health benefits, to the purchase of other goods, while maintaining the current scope of 100% employee involvement.

Employee safety: the Group considers the workers' protection to be of primary importance, setting itself the goal of maintaining high levels of safety, promoting the integration of safety in all company activities and focusing on continuous staff training. Therefore, by 2025, the Group is committed to certifying all companies with operating personnel to the Occupational Health and Safety Management System (ISO45001) (by the end of 2024, 97% of Group personnel will already be certified).

Sustainable vehicles: corporate fleet renewal according to the highest sector standards. By 2028, the electric/hybrid car fleet target is 22.5% (13.5% in 2024).

Waste: the Group is committed to maintaining the already achieved standards of sending more than 99% of special waste for recovery.

Renewable power: photovoltaic power installed at the company's headquarters that will save more than 1.3 ktons, in terms of tons of CO² avoided from 2024 to 2028.

Renewal of gas distribution assets: replacement of aging networks to reduce fugitive emissions of natural gas. Network digitalization and renovation in order to facilitate the introduction of renewable gases (biomethane, hydrogen-methane blending, etc.).

Renewal of domestic meter fleet: selection of meters capable of receiving the new gas mixtures and made of recyclable material. Gradual replacement of meters with GPRS communication technology in favor of NB-IOT will allow a number of spent batteries for disposal.

Reduction of CO² and CH⁴ emissions: through the implementation of energy efficiency measures for the preheating cycle in REMI cabins and the adoption of innovative methods to search for CH4 leakage in the networks.

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

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

Ascopiave Group – 11th ITALIAN CEO CONFERENCE – 18 57 th June 2025

• Gas distribution is currently a local monopolistic activity managed under concessions granted by municipalities.
• Italian gas distribution sector was liberalized in 2000 according to the European Union Rules
• The law established a mechanism of competition for the market: concession must be awarded only through public tenders.
• The distributor is responsible for the operation, the development and the maintenance of the distribution network (operational expenses and investments), according to the concessional agreement signed between the operator and the municipality
• The Italian Regulatory Authority for Energy, Networks and Environment (ARERA)
  • ✓ sets the tariffs to be applied to cover the cost of capital and for the operations of the service
  • ✓ provides rules regarding the minimum standard service levels.
• The distributor gives access to any requiring gas sales company that has the right to use the network to supply gas to its customers (third party access).

Gas distribution: sector key figures

Gas distribution key figures (*)	2023
No. of operators in Italy	186
Municipalities served	7,359
Volumes of gas distributed (bln/scm)	25.6
No. of users served (mln)	21.9
Length of the gas distribution network (km)	271,211
Regulatory asset base (RAB) (bln€) (**)	19

Currently gas distribution sector is strongly concentrated:

• about 55% of RAB (**) is held by Italgas and F2i, the only operators with a national rank (***)
• about 30% of RAB (**) is held by 15 medium size operators (RAB > 100 m€), with a regional relevance
• about 15% of RAB (**) is held by small size operators

(*) ARERA data; (**) Ascopiave estimate; (***) On 1st April 2025, Italgas closed the acquisition of the share capital of 2i Rete Gas.

• In order to improve the economic efficiency of the sector, since 2007 the legislation has established that the tenders must be called to assign concessions for the management of the service in wide geographical areas, grouping neighbouring municipalities (ATEM).
• The national government constituted 177 ATEM nationwide.
• Municipalities belonging to a single ATEM must appoint a local entity to act as contracting authority for the ATEM.
• The law established the deadline by which each ATEM contracting authority must call the tenders.
• In 2011 the national government issued some decrees establishing the general contents of the call for tenders, that must be fulfilled on the base of the local needs for investments to be defined by the local contracting authority. The standardization was aimed at encouraging competition and assuring transparency and effectiveness in the tender process.

The current rules governing the incoming tender processes will probably cause a further restructuring of the distribution sector.

A significant reduction in the number of operators is expected, as the participation in the public tenders requires from the potential competitors strong financial capability and important organizational and technical expertise.

Tenders process is currently slowed down by procedural difficulties. All the contracting stations failed in publishing the call for tenders respecting the deadlines provided by the law.

Standards to evaluate economic and technical offers

• A - Economic offer (maximum score: 28)
• Discount on gas distribution tariffs
• Discount on prices for specific services provided by the distributor to end users
• Fee to be paid to municipalities awarding the concession (cap on the fee level: 10% of the capital cost components of VRT (Total Revenues Constraint) = 10% x ( CI x rd + AMM ))
• Obligation to extend the distribution network (meters of pipes per end user that imply the obligation to connect new potential end-users)
• Investments to improve energy efficiency
• B - Offer concerning safety and service quality (maximum score: 27)
• Network inspections in order to prevent gas leaks (percentage of gas network annually checked)
• Performance of the emergency service and of the gas odorization service
• Improving the level of other quality standards set by the Authority

C - Offer concerning the development and the maintenance of the network (maximum score: 45)

• Appropriateness of the network operation analysis
• Investment plan for the extension and the increase of the capacity of the distribution network; the evaluation concerns: the tangible benefits expected by the investment proposed, the accuracy of the technical projects as well as the quantities of new pipes to be made
• Investment plan for the maintenance
• Technological innovation

In the event that the public tender should not be awarded to Ascopiave, the winner must pay to the Group, as the current owner of the networks, a compensation:

• (a) the compensation must be calculated in accordance with the terms of the agreement implementing the concession or direct award (as the case may be), provided that the agreement was signed before 11th February 2012
• (b) or, if this is not provided for, the compensation must be calculated in accordance with the Guidelines set by the Ministry of Economic Development (Decree 22nd May 2014)
• (c) contributions paid by private users in the past for the construction of part of the network must be deducted (valuation of these are in accordance with the tariff regulation) (*)
• (d) the Energy National Authority (i.e. ARERA) must verify whether the compensation has been evaluated in accordance with the law
• (e) the organizer of the tender bid must take into account the observations issued by the ARERA.

(*) In the evaluation of RAB contributions paid by private users are currently deducted.

Tariff regulation for the incoming ATEM concessions

Difference between Compensation and RAB

At the starting date of the new concession:

• if the winner of the public tender is the current incumbent operator, the new RAB is equal to the previous one;
• if the winner of the public tender is a newcomer, the new RAB is equal to the compensation paid by the newcomer to the outgoing operator.

Compensation at the end date of the ATEM concession

The compensation is calculated as the sum of (a) the value of the stock of capital existing at the start date of the concession, that is equal to the initial compensation properly updated to take into account the depreciation occurred during the concessional period, and (b) the value of the investments made during the concessional period.

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

- 19.6 bln€ > total expenditure

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 660 bln€ 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.

European

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.

(*) Compared to 1990 levels; (**) Compared to estimated 2030 energy consumption (based on the 2020 reference scenario); (***) Compared to Fit for 55 data.

In the energy transition process, gas represents a key source that will ensure the shift from a fossil fuel-based energy model to a low-emission one

(*) Biomethane and hydrogen; (**) Scenarios developed in 2024 by leading national operators in the gas transportation and electricity transmission sectors.

Ascopiave Group – 11th ITALIAN CEO CONFERENCE – 18 67 th June 2025

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.
