The new infrastructure grid – Green gases

Significant growth in demand for green gas is expected in the coming years in order to accelerate decarbonization, increase energy independence, and foster integration with the electricity grid

Biomethane

• ✓ Renewable source (produced from biomass of agricultural origin) that already in the medium term can provide a sustainable alternative to natural gas
• ✓ Sustainable: carbon neutral source that can also significantly reduce emissions from the agricultural sector by promoting waste reuse and circular economy

Hydrogen

• ✓ Carrier that can be produced emissionfree from RES by electrolysis
• ✓ Viable alternative to natural gas in the long term, especially for decarbonization of hard-to-abate and heavy transport sectors
• ✓ Promotes integration between electricity and gas sectors

Potential benefits of green gases

Programmable electricity generation

Possibility of storage and transport with existing gas networks

Multiple end uses (e.g. transport, industrial uses, electricity generation)

Application in light of the integration with the electricity network (e.g. power-to-gas-to-power)

Significant contribution to the reduction of emissions

Focus: hydrogen incentives

PNRR makes approximately €3.65 billion available for projects suitable for hydrogen development

The new infrastructure grid

The gas network will require technological and infrastructural adjustments to facilitate the introduction and transport of "green" gases in order to decarbonise the system

Dynamics of the gas distribution sector in Italy

Gas distribution in Italy is now a mature and consolidated sector, with the need to renew itself to meet the challenges arising from the evolution of the energy system

The gas distribution sector recorded a gradual consolidation, favored by:

• ✓ Rules for awarding concessions for ATEM¹
• ✓ Economies of scale deriving from centralised management

No. of gas distribution operators in Italy²

The energy system transformation scenario will require a renewal of the sector, in terms of:

• ✓ Technological and industrial renewal
• ✓ Rethinking of the business management methods

Examples of necessary renovations

Upgrade of distribution networks

✓ To safely allow the distribution of gas with increasing percentages of hydrogen

Reduction of CO² and CH4 emissions

✓ Through operational efficiency measures aimed at greater sustainability of the activities

Regulation of the gas distribution industry

Current sector regulation ensures stability and risk containment while the regulatory evolutions expected by ARERA are geared toward total cost efficiency and encouraging innovation and solutions aimed at decarbonization

Current	Regulatory	Regulatory
regulation	evolution	innovation
➢ The current legislative and regulatory framework is characterised by stability and transparency and guarantees: ✓ Stability of economic results and cash flows Recovery of the value of the investments ✓ made at the end of the concession ✓ Recognition of operating costs based on predefined productivity recovery rates ✓ Rate of return on capital updated periodically on the basis of market parameter evolution ➢ The current regulation therefore ensures a limited operational risk for gas distribution activities	➢ ARERA proposes a gradual introduction of a tariff regulation for Expense and Service Objectives (ROSS), oriented to the total efficiency of the service (from 2026): ✓ Integrated recognition of operational costs and efficient capital costs ✓ Standard capitalization coefficients ✓ Revision of the incentive mechanism ✓ Selectivity of recognizable investments, to be justified with cost-benefit analyses The paradigm shift will support the ➢ rationalisation of the sector: Opportunity for efficient companies to ✓ improve their profitability ✓ Risk of under-remuneration of capital for inefficient companies Alignment of tariff regulations for ✓ infrastructure services	➢ DCO 250/2021/R/gas – Pilot projects of innovative solutions ✓ Optimized network management ▪ Bi-directionality, accumulation, loss reduction ✓ Innovative uses of networks ▪ Biomethane, hydrogen, "green" gas injection ▪ Renewable gases in industrial processes ▪ Electrolysers and methanation Power to gas, power to hydrogen, CO capture ▪ 2 ✓ Technological / management innovation ▪ Network digitization ▪ Energy recovery in decompression and re compression ▪ Energy efficiency in preheating ✓ Convergence between the gas and electricity sectors ✓ Reduction of methane emissions into the atmosphere Resolution 404/2022/R/gas - Regulations for the application of ➢ the premium tariff mechanism to support the innovation of infrastructure in the natural gas sector in the areas of intervention identified by DCO 250/2021/R/gas mentioned above

Dynamics of gas and energy prices

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

Russian gas supply replacement, progressive technology substitution for electric generation and electrification of consumption are the main substantive elements underlying an energy price outlook characterized by significant levels of volatility along the transition path. The last period has witnessed a substantial decrease in prices related to the completion of storage and concomitant low demand levels related to decreased industrial production and off-normal temperatures.

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

European energy policies have introduced increasingly challenging decarbonization targets, and national energy policies have followed the impetus from EU initiatives.

The Plan for Ecological Transition (PTE) has among its goals to 2050

• ✓ Setting greenhouse gas emissions to zero
• ✓ Revolutionize mobility to its full sustainability
• ✓ Minimize pollution and contamination of air, water and soil
• ✓ Setting the path toward a zero-waste circular economy and healthy, sustainable agriculture

The main goal of the RePower EU Plan is to reduce European countries' dependence on Russian fossil fuels by leveraging: diversification of energy sources, acceleration of energy transition, and stringent energysaving targets

"Plan for Ecological Transition" ; Notes: ¹Arithmetic mean of prices defined for each geographic market area; ²Budget Law 2023

Renewables in Italy show a trend of substantial growth over the past 10 years with a total installed capacity of ~60 GW.

However, to achieve national decarbonization targets to 2030 will require at least 60-65 GW of new RES capacity to be installed in Italy requiring substantial investments (€ 40-50 bn to 2030) and integrated planning at temporal and geographic levels.

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

In 2021, there is 115.8 TWh of generation from renewable sources. Since 2020, there has been an 11% growth in wind generation and 2% growth in photovoltaic generation, compared with a decrease in hydroelectric (-2.43%).

Thus, there is a marked change in the coverage of electricity demand: traditional thermal sources reduced from 74% in 2005 to 51% in 2021, while RES increased from about 14% to 36%, with a greater focus on wind and photovoltaics since 2011.

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

Italy's renewable mix is characterized by a general growth trend, emphasized by measures implemented at the EU level to address the Russian-Ukrainian crisis. By 2040, 65% of the projected installed renewable capacity will consist of photovoltaic

4. Strategic plan 2022-26

Strategic pillars Plan projections

Shareholder remuneration

The plan projections have been elaborated and defined taking into consideration both the main risk elements typical of the reference sectors, and the characteristics of Ascopiave

Main rationals

Uncertainty about the start of ATEM tenders

• The uncertainty about the timing of tenders and subsequent award of concessions suggested the development of a scenario analysis based on various hypotheses¹ :
  • o Scenario A: increase in the perimeter of activities managed in gas distribution sector only through M&A and organic growth as by the end of the plan period no ATEM tender is able to complete its award process;
  • o Scenario B: in addition to the growth expected in Scenario A, 4 ATEM tenders are assumed to be initiated and awarded in 2026 and, as a result, a significant increase in networks and users managed.

Pursuit of rational goals in terms of efficiency and investments

• The projections reflect the goals reasonably achievable by the Group
• Operating and investment costs incorporate:
  • o Inflation dynamics (+)
  • o Economic-management efficiency targets (-)

Implementation of M&A initiatives and diversification into other activities

▪ Achieving reasonable growth targets through M&A and investment initiatives in the renewable energy sector and diversified businesses

The plan requires the undertaking of a significant amount of investment, directed both at the maintenance and development of the existing network and the expansion of activities on new synergistic businesses

Note: ¹Net of any disinvestments.

Investments in gas distribution

Most of the planned investments are in gas distribution, with significant interventions on current perimeter and possible additional gains in case of ATEM tender award

Investments in renewable energy

The Group aims to expand the portfolio of RES generation power plants both through M&A transactions and the development of new greenfield plants

Net cumulative greenfield investments¹ Net investment and maintenance @ 2026 ¹ cumulated @ 2026

Gross operating margin evolution

The implementation of the considered initiatives will lead, over the plan horizon, to a progressive and stable growth in the value generated in terms of EBITDA

Note: ¹Preliminary.

Key prospective data - Gas distribution

Growth prospects, both by internal and external lines, will result in further consolidation of the Group in the gas distribution sector

Key prospective data - Renewable energy

The growth strategy will also enable the Ascopiave Group to significantly increase its share in the renewable energy sector

Ascopiave Group – Strategic Plan 2022-2026 62 Note: ¹Preliminary. ²The amount 371 GWh as of 2026 does not include the estimated expected output of 65 GWh from a 36 MW wind power plant built by 2026 and that will enter in production in 2027

Key prospective data - Environmental sustainability

Through a strategy of energy efficiency and integration of renewable energy sources, the Ascopiave Group will be able to generate a positive climate impact by reducing CO² emissions

-2.3 kton CO²

-103 kton CO² p.a.

Through continuous efficiency gains in its consumption (-3% p.a.), Ascopiave Group will be able to save approx. 2.3 kton CO² emissions over the strategic plan period (scope 1 and 2)

The investment plan, of approximately 870 mln€ under the more conservative scenario, is equally allocated to the current perimeter and the expansion of the company's activities. Around €500 mln of the plan will be financed through resources from the exercise of put options in EstEnergy and HeraComm stakes
