3. Context and market trends

The Macroeconomic Context

There is a deceleration in GDP growth in 2023, which is adjusted downwards to 0.8% from the 1.0% reported in the Economic and Financial Document ('DEF').

GDP deceleration causes are the
erosion of household purchasing power
due to high inflation, the uncertainty
caused by the war in Ukraine, the
stagnation of the European economy
and the contraction of world trade.

Outlook on investment and credit

• ✓ Investment expenditure in 2023 is lower than in the period 2021-2022, mainly due to tighter financing conditions and higher interest rates. These phenomena result from repeated interest rate increases by the ECB. The trend scenario sees investment expenditure increasing by 2.8% in 2024, with a lower growth trend in 2025 and 2026 (2.3% and 1.9% respectively).
• ✓ The trend in public investment is affected by the grants and loans of the National Recovery and Resilience Plan, as well as the reclassification of tax credits related to the superbonus. The result is a ratio of government gross fixed capital formation to GDP of 2.9% in 2023, 3.2% in 2024, 3.4% in 2025, and 3.2% in 2026.

The European and Italian decarbonisation goals

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

Ascopiave Group – Strategic Plan 2024-2027 23 Note: ¹Compared to 1990 levels; ²Compared to projected energy consumption in 2030 (based on 2020 reference scenario); ³Compared with data from Fit for 55.

Role of the gas sector in the energy transition

In the energy transition pathway, gas represents a key source that will have to ensure the transition from a fossil fuel-based energy model to one with low emissions

Expected gas consumption in Italy¹

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
• ✓ 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

New demand scenarios for 2040

To achieve decarbonization levels by 2040, greater reliance on carbon capture and storage (CCS) is necessary.

The Italian Long-Term Strategy on Greenhouse Gas Emission Reductions foresees a contribution from CCS of 40 Mt/year

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

The regulation of ATEM tenders (1/2)

Tenders for the allocation of gas distribution services for ATEM are regulated by national-level legislation and regulation, subject to subsequent refinements. The market opening process is characterized by significant delays.

Genesis of the legislation Over the past twenty years, the natural gas sector has undergone profound changes, which have also affected the methodologies and objectives of tariff regulation, as well as the methods for identifying the operators of natural gas distribution facilities. ➢ Legislative Decree 164/2000 (known as the "Decreto Letta") established the principle that the service must be entrusted through a public tender (competition for the market). ➢ A series of subsequent interventions have further defined the liberalization process: ✓ Identification of 177 ATEM (later reduced to 171) for the allocation of concessions¹ ; ✓ Definition of criteria for evaluating bids (Ministerial Decree 226/2011 and subsequent amendments): economic offer, investment plan, safety standards, and service quality. Current status In the aftermath of the issuance of ministerial decrees, the organization of tenders encountered numerous implementation obstacles, which delayed the start of the tenders. ➢ By the end of 2023, the tender procedures for 8 areas had concluded (Milano 1, Torino 1, Torino 2, Belluno, Valle d'Aosta, Udine 2, Napoli 1, La Spezia). However, only 4 concessions had actually been initiated (Torino 2, Milano 1, Napoli 1, Valle d'Aosta). ➢ Tenders in progress: 7 ➢ Tenders suspended or cancelled: 24 ➢ Calls sent to ARERA: 12 (4 of which are awaiting publication)

Ascopiave Group – Strategic Plan 2024-2027 31 Notes: ¹Each ATEM is subject to a single tender, and within each area, the networks are managed by a single operator who will be transferred ownership of the facilities upon payment to the outgoing operators of their reimbursement value.

The regulation of ATEM tenders (2/2)

Recently, some significant measures have been adopted (or are currently being adopted) to simplify and expedite the process of publishing tender notices and to update the criteria for evaluating bids.

Disposal of networks owned by local authorities

➢ The Law of August 5, 2022, No. 118 (Article 6, paragraph 1, letter b) provides that if a local authority or a network asset company, during the tendering process for the natural gas distribution service, intends to sell its ownership of the networks and distribution and metering facilities, said networks and facilities shall be evaluated according to the residual industrial value calculated based on the "Guidelines on criteria and methods for assessing the reimbursement value of natural gas distribution facilities" of April 7, 2014, approved by the Minister of Economic Development on May 22, 2014.

Updating Ministerial Decree 226/2011 (tender criteria)

• ➢ The MASE¹ , in implementing Law No. 118/2022, aims to update Ministerial Decree No. 226 of November 12, 2011, "Regulation for the tender criteria and evaluation of bids for the allocation of the natural gas distribution service" and subsequent amendments. To this end, it has initiated a consultation with ARERA, AGCM, and sector trade associations (the so-called "Cabina di regia").
• ➢ The future decree aims to:
• ✓ Mitigate significant issues related to the existence of informational asymmetries in the trilateral relationship between outgoing operators, local authorities, and incoming operators;
• ✓ Introduce important coordination elements between the criteria for valuing interventions and the objectives of optimizing and rationalizing the use of energy resources;
• ✓ Introduce a significant update of the criteria for technological innovation, aiming to strike the right balance between the need to implement a forwardlooking vision and the necessity to remain anchored to parameters of immediate feasibility as well as economic and financial sustainability..

Simplification of ARERA verifications

• ➢ ARERA intends to consolidate into a single procedure the two separate procedures currently provided for its two competencies regarding gas tenders, namely those related to observations on reimbursement values and those related to observations on tender documents prepared by contracting authorities. Additionally, ARERA aims to introduce provisions aimed at accelerating and streamlining procedures for verifying discrepancies between VIR (values of reimbursement) and RAB (regulated asset base) even for ongoing procedures.
• ➢ Relevant measures published by ARERA:
• ✓ Resolution 35/2024/R/gas
• ✓ DCO 36/2024/R/gas

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, the availability of LNG to compensate for the decrease in flows 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

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

Renewables in Italy show a trend of substantial growth over the past 10 years with a total installed capacity of ~70 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 establishing sound market conditions, investing in essential infrastructure and implementing effective regulatory and policy frameworks.

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

In 2022, renewable energy sources recorded a production of approximately 100 TWh (down by approximately 14% compared to 2021)

Therefore, there has been a significant change in electricity production³ : traditional thermal sources have decreased from 84% share in 2005 to 64% in 2022, while renewable energy sources have increased from approximately 16% to 36% over the same period.

Ascopiave Group – Strategic Plan 2024-2027 36 Note: ¹Elaboration of latest available TERNA data. ²Considering exclusively production from natural sources (excluding pumped storage); ³Gross production.

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

Worker safety: the Group considers the protection of workers 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 (ISO 45001) (by the end of 2023, 96% of Group personnel will already be certified).

Sustainable vehicles: corporate fleet renewal according to the highest industry standards. By 2027, the electric/hybrid car fleet target is 23.5% (9.5% at 2023).

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

Renewable power: photovoltaic power installed at the company's headquarters that will save, in terms of tons of CO² avoided from 2023 to 2027, more than 1.3 ktons.

Gas distribution asset renewal: replacement of ageing networks to reduce fugitive emissions of natural gas. Digitisation and renovation of the network 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 reduction in quantity of spent batteries for disposal.

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

4. Strategic plan 2024-2027

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 2027 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

Ascopiave Group – Strategic Plan 2024-2027 60 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 investments Net investment ¹ @ 2027 ¹ cumulated @ 2027

m€ 99 122 221 122m€ in M&A investments in renewable energies for the acquisition of wind (35 MW) and photovoltaic (40 MW) plants with a remaining useful life of 25 years, and an expected annual output of 119 GWh when fully operational

Investimenti greenfield M&A Greenfield investments

Development of greenfield photovoltaic plants: plants already authorised or at an advanced authorisation stage with a nominal capacity of 37.9 MW and annual production when fully operational of 46 GWh. Planned commissioning in 2025 and 2026.

Development of greenfield wind farms: plants with a nominal capacity of 36 MW for which the authorisation process is expected to start in 2024. Given the length of the authorisation procedures, a start of production is assumed after the plan horizon.

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

in case of ATEM tender award (Scenario B)

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 2024-2027 65 Note: ¹The amount 387 GWh as of 2027 does not include the estimated expected output of 65 GWh from a 36 MW wind power plant built by 2027 and that will enter in production in 2028.

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

-1.7 kton CO²

-136 kton CO² p.a.

Through continuous efficiency gains in its consumption (-2% p.a.), Ascopiave Group will be able to save approx. 1.7 kton CO² emissions over the strategic plan period (scope 1 and 2)

Ascopiave Group's consolidation in the sector of green energy generation will contribute to an average annual emission reduction of about 136 kton of CO² . A further contribution in terms of CO² savings is expected from initiatives related to Green Hydrogen and Biomethane.

Energy recovery from the decompression of network gas, using an innovative cogeneration turboexpansion process, shows that the amount of CO² emitted into the atmosphere will be reduced by approx. 533 tons compared to conventional decompression systems.

Ascopiave Group – Strategic Plan 2024-2027 66 Note: ¹Estimate of emissions in 2027 does not consider the impacts of increased gas consumption resulting from the construction of cogeneration turbo-expansion plants.

In both the scenarios examined, the economic results to 2027 are expected to show a growing trend

Dividend distributed by Ascopiave and historical dividend yield 2017-22 and prospective dividend yield 2023-27

Ascopiave Group – Strategic Plan 2024-2027 72 Notes: ¹Historic average dividend and dividend yield calculated by considering only the ordinary dividend; ²Dividend approved and distributed during 2028 with reference to fiscal year 2027; ³Dividend yield calculated as the ratio between distributed dividend and the share price at the end of the year

Ascopiave Group is a well-established entity with a balanced portfolio of assets, characterized by a low risk profile, and a track record of growth

The strategy that will guide Group's actions in the coming years is based on the growth of core businesses, diversification into new synergistic activities, economic efficiency and innovation

The investment plan, of approximately 620 mln€ under the more conservative scenario, is equally allocated to the current perimeter and the expansion of the company's activities. Around 290 mln€ of the plan will be financed through resources from the exercise of put options in EstEnergy and HeraComm stakes

Expected results foreshadow sustainable growth that will create value for shareholders and stakeholders

The plan provides for the distribution of a remunerative dividend during the period to benefit the Group's shareholders
