CERTIFIED

Ascopiave is a leading operator in the Italian natural gas distribution sector.

The Group is also active in producing renewable energy and holds minority stakes in companies operating in the utilities, telecommunications and integrated water services sectors.

The current corporate business structure is the result of a strategic repositioning process that began in 2019, which saw the Group gradually exit the gas and energy sales sector and strengthen its position in the core gas distribution business, as well as diversifying into the renewable energy sector.

The process was recently completed (namely in the period June-October 2025) with the definitive sale to the Hera Group of the minority shareholdings Ascopiave held in Estenergy and Hera Comm.

Such transactions made it possible to finance a further growth initiative in the distribution sector, namely the acquisition from the A2A Group of a set of concessions in Lombardy and from Sime Partecipazioni of a set of concessions in Lombardy, Emilia Romagna and Piedmont.

Therefore, the Group is now the second largest operator in the sector in Italy, consolidating its leadership position in Veneto and Lombardy.

The tender participation strategy identifies Northern Italy as the geographical focus

img-2.jpeg

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

img-3.jpeg

Available experience suggests that the timeframe for service award can be quite lengthy, also due to legal disputes that typically accompany the awarding decisions

Ascopiave is evaluating the possibility of establishing partnerships for participation in ATEM tenders or to seize new M&A opportunities

> Through partnership operations, the Group seeks to increase its competitive chances and diversify financial and operational risks through participation in the results of a broader portfolio of concessions

Given the complexity of the underlying assessments - including their uncertainty and transformative nature - the plan provides a preliminary estimate of the possible economic and financial impacts of this further growth option, highlighting them distinctly and specifically

CERTIFIED

  • 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 relevant legislation established a mechanism of competition for the market: concessions should 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 concession 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).

Public tenders for the assigning of concessions

emarket
adv storage
CERTIFIED

In order to improve the economic efficiency of the sector, since 2007 the legislation has established that the tenders have to be issued to assign concessions for the management of the service in wide geographical areas, grouping neighbouring municipalities (ATEM).

The national government created 177 ATEM nationwide (afterwards consolidated to 172).

Municipalities belonging to a single ATEM should appoint a local entity to act as contracting authority for the ATEM.

The law established the deadline by which each ATEM contracting authority should issue the call for tenders.

In 2011 the national government issued some decrees establishing the general contents of the call for tenders, that should 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 such public tenders requires strong financial capability and important organizational and technical expertise to the potential competitors .

Tender processes are currently slowed down by procedural difficulties. All the contracting stations failed to publish the call for tenders in compliance with the deadlines originally provided by the law.

With the 2023 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.

New demand scenarios for 2040

Tenshorise distribution and commercial use strictly prohibited

CERTIFIED

The scenarios outlined in 2030 and 2040 decline at national level the decarbonization targets set at European level

img-6.jpeg

PNIEC Policy 2030

Energy efficiency, renewable electricity and the development of biomethane and green hydrogen are the levers on which the scenario relies to achieve the target of reducing emissions by $55\%$ by 2030 compared to 1990 levels. In this scenario, the need to resort to carbon capture and storage technologies emerges.

PNIEC Slow 2030 - 2040

The slowdown in the implementation of decarbonization measures reflected in the scenario delays the introduction of hydrogen and biomethane and anticipates lower efficiency, thus maintaining higher levels of fossil natural gas compared to the Policy scenario.

DE-IT 2040

This scenario constitutes a possible pathway to achieve Carbon Neutrality by 2050 and relies on greater penetration of electric carrier in all sectors, maximizing the use of solar and wind generation. The use of hydrogen in final consumption is limited to the so-called "hard-to-abate" sectors (e.g., heavy transport, industrial processes that require gas as a raw material or reducing agent).

GA-IT 2040

This scenario constitutes a possible pathway to achieve Carbon Neutrality by 2050 and relies on greater penetration of hydrogen in all sectors, a different use of technologies and energy carriers in the mobility sectors (electricity, hydrogen, e-liquids, and biofuels), and increased use of carbon capture and storage, both in hard-to-abate sectors and in thermoelectric power generation.

In order to achieve the challenging emission reduction targets, all scenarios involve the use of carbon dioxide capture and storage technologies (CCS), with a contribution of 4 Mt/year to 2030 (in the PNIEC Policy scenario), and of 34 Mt/year and 40 Mt/year to 2040 respectively in the DE-IT and GA-IT scenarios.

The new infrastructure network

Tsimborse distribution and commercial use strictly prohibited

CERTIFIED

The gas network will require technological and infrastructural upgrades to facilitate the injection and transport of «green» gases, with a view to decarbonising the system

Production and injection of «green» gases

☑ Starting from the significant production of biogas, a considerable increase in the production and injection of biomethane1 into the network is expected
☑ Biomethane represents the most feasible carbon-neutral option as it is an already available renewable energy source
☑ Integration with the electrical system will enable the production and injection of both hydrogen and synthetic gases into existing networks, leading to a reduction in emissions

img-13.jpeg

Withdrawal and final uses

☑ Existing gas infrastructure can transport and store «green» gases and will be essential for supplying increasing quantities of gas to end users
☑ he end uses will be diverse: from industry to residential, from transport to the tertiary sector
