Italgas: Europe's Gas Distribution Empire — 188 Years of Infrastructure Dominance

I. Introduction: A Company Older Than Its Country

Picture Turin in the autumn of 1837: the Kingdom of Sardinia is fragmenting into duchies and papal states, Garibaldi is still a merchant marine officer, and the concept of a unified Italy remains a dreamer's fantasy. Yet here, on a cobblestone street outside Porta Nuova, workers are laying the foundations for something revolutionary—the first gas pipes that would light Turin's streets and, eventually, an entire nation's homes.

"In August 1837, French engineer Hippolyte Gautier obtained approval for the charter of a Gas Lighting Company for the City of Turin." Italgas was founded in 1837 and is historically known for introducing gas into Italian homes, contributing to the country's economic and social development.

How does a company founded before Italy even existed as a nation become Europe's largest gas distributor and a digital transformation leader? This is the question at the heart of the Italgas story—a narrative that spans 188 years of technological disruption, state intervention, privatization, and reinvention.

Today, with the acquisition of 2i Rete Gas complete, Italgas Group has become "the first operator in gas distribution in Europe with more than 6,500 employees, 12.9 million customers served in Italy and Greece, 154,000 kilometers of grids and more than 13 billion cubic meters of gas distributed every year."

The themes that emerge from Italgas's journey read like a masterclass in infrastructure durability: the power of regulated monopolies, digital transformation in legacy industries, M&A as a consolidation engine, and the strategic pivot from obsolescence risk to energy transition opportunity. We will explore each inflection point that transformed a Piedmontese gas lighting company into Europe's dominant gas distribution champion.

II. Origins: Before Italy Was Italy (1837-1862)

The story begins with Hippolyte Gautier, a French engineer with vision and the Lyon banking connections to fund it. The company was formed as a joint-stock enterprise with an initial planned capital of 840,000 Piedmontese lire, of which 722,000 were subscribed by investors from Lyon. This Franco-Piedmontese partnership established a pattern that would repeat throughout the company's history: foreign capital and technical expertise combined with local commercial acumen.

Within two years, the company was already supplying 1,600 streetlights, replacing the old oil lamps that had dimly illuminated Turin's nights. The production workshop was built outside Porta Nuova, with coal imported from Newcastle—a testament to the global nature of even this earliest industrial endeavor.

The company faced immediate competition. In Turin, the company faced competition from other gas producers, particularly the Gas-Light Consumers' Cooperative, founded by several industries that used both forms of energy to power their machinery. Consequently, the Gas Lighting Company for the City of Turin sought new markets beyond the Piedmontese capital and secured concessions to manage gas distribution services in Palermo, Bergamo, and Cremona.

This early expansion strategy proved prescient. In 1862, following this initial expansion, the company was renamed the Italian Gas Company (Società Italiana per il Gas), highlighting its new national scope. The rebranding coincided with Italian unification—the company had literally grown alongside the nation it would serve.

The Lighting Company acquired a share in 1851 on the Turin Stock Exchange. A public listing in the Piedmontese capital established Italgas as one of Italy's earliest publicly traded industrial enterprises—a status it would maintain (with interruptions) into the present day.

The significance of these early years cannot be overstated. Italgas wasn't simply providing a service; it was creating infrastructure that would shape urban development patterns for generations. Gas pipes determined where people could live, work, and conduct business after dark. The concession-based model established in these foundational years—securing exclusive rights to serve defined geographic territories—would remain the bedrock of the company's competitive moat for nearly two centuries.

III. Electricity Disruption & Survival (1880s-1950s)

By the 1880s, Italgas confronted an existential threat that would seem familiar to any business strategist today: technological disruption. The 1880s marked the rise of electric energy, which would soon dominate lighting applications. Gas companies were therefore forced to explore new directions.

Rather than fight the inevitable, Italgas's leadership made a strategic pivot that would define the company's second century. The industry began focusing on heating, cooking, and refrigeration—applications where gas's advantages over electricity remained compelling. This shift from illumination to thermal applications transformed gas from a lighting fuel into a household utility.

In 1900, Italgas was listed on the Milan Stock Exchange. The national listing reflected the company's expansion beyond its Piedmontese roots and positioned it to access capital markets during Italy's industrial boom.

The 1920s brought aggressive expansion under President Rinaldo Panzarasa. During the 1920s, under the presidency of Panzarasa, the company pursued expansion by acquiring demunicipalized gas services and investing in related sectors such as chemical processing. The diversification into chemical processing—leveraging byproducts from coal gasification—represented early vertical integration thinking.

But the global economic catastrophe of 1929 brought this expansion to a grinding halt. In 1930, Alfredo Frassati was appointed president of the company. His main task was to restore the company, which had been suffering the effects of the 1929 Great Depression. Starting in 1934, Frassati initiated a strict restructuring process, divesting from activities not directly related to gas production and distribution.

Frassati's restructuring established a pattern of disciplined focus that would be repeated multiple times in the company's history: when faced with crisis, return to core competencies. Strip away the diversifications, concentrate resources on the fundamental business, and emerge leaner.

During the Second World War, gas service in Turin and throughout central and northern Italy faced severe restrictions due to the shortage of raw materials. Italgas facilities sustained significant damage from bombings and acts of war.

Yet even amid wartime devastation, the seeds of the next transformation were being planted. During this period, the company began its first experiments with natural gas, and in 1950, the first urban gas distribution network was built in Lodi.

This quiet experiment in Lodi—a mid-sized Lombardian city—marked the beginning of natural gas distribution in Italy. The shift from manufactured "town gas" (produced by coal distillation) to piped natural gas represented another fundamental technological transition, one that would position Italgas at the center of Italy's postwar energy infrastructure.

IV. The ENI Era: State Control & Methanization (1967-2003)

Post-war Italian industrial policy featured state-directed development of strategic sectors, and energy sat at the apex of national priorities. In 1967, control of Italgas was acquired by ENI, the then Italian National Hydrocarbons Authority (Ente Nazionale Idrocarburi).

For Italgas, absorption into the ENI empire brought access to enormous capital resources and alignment with national energy policy. The tradeoff was loss of independence—the company became a tool of state industrial planning rather than an autonomous commercial enterprise.

Starting in the 1970s, Italgas played an important role in the natural gas conversion (methanization) of the country. In the 1980s, it established Italgas Sud, a new entity tasked with carrying out the major project of bringing natural gas infrastructure to Southern Italy (Mezzogiorno).

The methanization of Italy represented one of Europe's largest infrastructure projects of the postwar era. Converting an entire nation from manufactured gas to natural gas required replacing millions of appliances, retrofitting pipes, and building entirely new distribution networks in regions that had never had gas service at all. Italgas became the execution arm of this national transformation.

In this period, the most significant event was the 1982 acquisition of the Compagnia Napoletana di Illuminazione e Scaldamento col Gas (abbreviated as Napoletanagas S.p.A.), which had been distributing gas in Naples since 1862. This acquisition brought another historic operator—one as old as Italgas itself—under the company's umbrella, cementing its position in Southern Italy.

The company also experimented with diversification. Between the late 1980s and early 1990s, Italgas expanded into the drinking water and urban solid waste management sectors before refocusing on natural gas. At the same time, international expansion continued through subsidiaries operating in Argentina, Brazil, Greece, Portugal, Spain, and Hungary, employing over 10,000 people.

This international footprint represented ENI's ambitions to create a global gas distribution player. Yet the diversification would prove short-lived—the pattern of returning to core business during restructuring would reassert itself.

In November 2002, as part of a broader restructuring of its activities, Eni launched a takeover bid for all outstanding shares of Italgas. The following year, after more than 150 years, Italgas was delisted from the Milan Stock Exchange.

The delisting removed Italgas from public view. It became one operating unit within ENI's vast portfolio—valuable, but not independently strategic. Subsequently, Eni consolidated its regulated gas operations under Snam, creating a new Group encompassing the various segments of the gas supply chain: transportation through Snam Rete Gas, storage via Stogit, regasification through GNL Italia, and distribution with Italgas.

This restructuring established the framework for what would come next. By separating distribution (Italgas) from transportation (Snam Rete Gas), storage (Stogit), and regasification (GNL Italia), ENI created organizationally distinct units that could be strategically repositioned as European regulatory requirements evolved.

V. INFLECTION POINT #1: The Snam Years & Regulatory Restructuring (2003-2016)

The early 2000s brought European Union regulatory pressure for unbundling—separating the various links in the gas value chain to promote competition. On February 12, 2009, Snam Rete Gas S.p.A. acquired 100% of Italgas S.p.A. from Eni S.p.A. for 3.07 billion euros, and 100% of Stoccaggi Gas Italia S.p.A. for 1.65 billion euros. Payment was made through a capital increase of 3.5 billion euros and a 1.3-billion-euro loan. The transaction closed in July 2009, creating a group with a gas transportation network of 31,500 kilometers, a gas distribution network of 58,000 kilometers, and a storage capacity of 14 billion cubic meters.

Within Snam, Italgas operated as the distribution specialist. But the combination created strategic tensions. Distribution is a local, concession-based business with different characteristics than long-haul transmission. "In a constantly evolving market, local gas distribution activities now have different characteristics and needs than those of gas transportation, storage and LNG. The demerger of Italgas from Snam will significantly enhance the role of both companies in their respective businesses."

Meanwhile, the Italian regulatory environment was evolving. The ATEM concept was introduced: ministerial decree 226/2011 divided the Italian territory into 175 ATEMs ("minimum concession area") for the next tenders and defined an ATEM tender calendar.

The ATEM system created a consolidation imperative. Italy's gas distribution sector remained highly fragmented, with more than 200 companies working across 7,000 concession areas serving more than 20 million customers. The new tender framework would bundle these micro-concessions into larger territorial units, favoring scaled operators with capital for investment and operational expertise.

For a strategic thinker, the implication was clear: whoever controlled the largest, most efficient gas distribution platform would be best positioned to win ATEM tenders and consolidate the fragmented Italian market. But achieving that scale would require independence from Snam—the ability to pursue an aggressive M&A strategy unconstrained by parent company capital allocation priorities.

VI. INFLECTION POINT #2: The 2016 Spin-Off & IPO — Renaissance

In March 2016, Italian gas-transportation company SNAM announced it was eyeing a spin-off of its Italgas domestic distribution unit. In a statement the company said it had launched a feasibility study on a "possible industrial and corporate re-organization designed to separate Italgas from SNAM."

The strategic logic was compelling for both entities. The spin-off would enable Snam to focus on its growth potential in the European market, while Italgas would become a major player in the consolidation of the distribution sector in Italy consecutive to new market rules in the distribution sector.

Snam had European ambitions. It would become one of the main shareholders of the Trans Adriatic Pipeline (TAP). The capital freed by separating Italgas could fuel that expansion.

The Board of Snam S.p.A. completed the spin-off of 86.5% stake in Italgas SpA for €2.8 billion on November 7, 2016. Pursuant to the transaction, Snam retained a 13.5% stake in Italgas SpA and existing shareholders of Snam S.p.A. received one share for every five shares held in Snam.

The spin-off coincided with the return to stock exchange of Italgas, which readopted the historic ticker "IG" left thirteen years ago, at the time of delisting wanted by Eni.

The timing proved challenging. The spin-off was not timed well just a day before the US election; the current uncertainties within Italian regulation changes further deterred potential investors. Italy was also approaching its constitutional referendum—the defeat of which would ultimately topple Prime Minister Renzi's government.

The stock would reach its lowest end-of-day price of €1.75 on December 5, 2016—just weeks after the IPO. By November 2025, that same share would trade above €8.20—its highest end of day price.

For value-oriented special situation investors, the 2016 dislocation represented opportunity. An essential infrastructure asset with regulated returns, trading at depressed multiples due to political uncertainty unrelated to the underlying business quality. The thesis: once political noise cleared, the market would recognize Italgas's asset value and growth potential.

Since the company's return to the stock market on 7 November 2016 through 31 December 2024, the total shareholder return reached 102.7%. That figure—doubling an investment over eight years while collecting substantial dividends along the way—vindicated the special situation thesis.

Into this newly independent company stepped Paolo Gallo. Paolo Gallo is Chief Executive Officer and General Manager at Italgas since 4 August 2016. He received his degree in Aeronautical Engineering from the Polytechnic University of Turin. He subsequently earned an MBA from Turin University.

Gallo's background was energy operations—not gas distribution specifically. From 2014 to 2016 he was the Chief Executive Officer of Grandi Stazioni S.p.A, of which he oversaw the privatization. Previously (from 2011 to 2014) he worked at Acea S.p.A., firstly as Chief Operating Officer and then as Chief Executive Officer. From 2002 to 2011 he was in the Edison Group, initially as Head of Strategy and Innovation, then as Chief Operating Officer and Chief Executive Officer of Edipower.

His experience at Acea—a major Italian multi-utility—and his track record overseeing the Grandi Stazioni privatization positioned him well for leading a newly independent, publicly traded infrastructure company through transformation.

VII. INFLECTION POINT #3: The Digital Transformation Strategy (2017-Present)

When Italgas presented its first strategic plan as an independent company in 2017, Gallo unveiled a vision that seemed almost incongruous for a nearly 180-year-old gas distribution company: digital transformation at the core of strategy.

"Digital transformation is at the heart of our strategy, the main enabler of the growth path that will allow us also to support the energy transition to achieve the EU 2030 and 2050 targets. Four years ago, we started our digitalization process with a visionary choice, the adoption of the public cloud."

The first step—migrating all applications to the cloud—seems unremarkable by today's standards but was genuinely pioneering for a European regulated utility in 2017. Most comparable companies were still debating whether cloud infrastructure was appropriate for critical operational systems.

In 2017, Italgas embarked on a digital transformation journey, resulting in the creation of Bludigit, a dedicated digital transformation arm. This new venture was created to enhance digital transformation within the energy and utilities sector, conceived to not only strengthen the digital evolution of Italgas but also to extend leading-edge solutions to industry peers. At the heart of Bludigit's offerings lies a suite of proprietary solutions, backed by a robust ecosystem of technological partners, and powered by the Digital Factory, their technological and innovative hub.

Since the inauguration of the Digital Factory in 2018, Italgas has developed highly innovative proprietary solutions.

The creation of Bludigit as a separate subsidiary represented sophisticated strategic thinking. Rather than embedding technology capabilities solely within Italgas Reti (the operating company), Gallo created a standalone technology business that could serve external customers—effectively monetizing digital investments beyond internal efficiency gains.

The new organization, headed by Marco Barra Caracciolo, formerly CIO of Italgas, can rely on the skills of around 100 people and will allow both to increase the Group's internal efficiency, making the digital transformation even more central, and to offer the market the new proprietary technological solutions. Bludigit S.p.A., born in July 2021, controls assets worth around 100 million euros and more than 100 contracts for a total value of over 300 million euros.

The crown jewel of Italgas's digitalization effort is DANA—Digital Advanced Network Automation. In 2021, the Group launched its centralised command and control system (DANA - Digital Advanced Network Automation): by leveraging the already implemented digitalisation of assets, DANA enables 24/7 automatic remote monitoring and control of the network.

Leveraging already implemented asset digitization, DANA enables 24/7 automatic remote network monitoring and control, and is able to record and analyze data (e.g., gas pressure and volume measurements, odorization level, signals, and alarms). The information collected is processed with algorithms to anticipate and anticipate potential network malfunctions. DANA is now also able to manage biomethane connections to our network.

Consider what this means operationally: a gas distribution network spanning tens of thousands of kilometers, serving millions of customers, monitored and controlled in real-time from a centralized command center. The ability to detect anomalies, predict failures, and dispatch maintenance proactively transforms the economics of network management.

In December 2023, Italgas unveiled Nimbus—described as the world's most advanced hydrogen-ready smart meter. Nimbus, with its unique features, is one of the enablers of the distribution in the low-pressure network and to the end user of green gases and hydrogen blends. The new meter was entirely designed and developed by Italgas Reti and Bludigit. The new meter has undergone more than 300 laboratory tests to align with all international certification standards. Nimbus is capable not only of measuring natural gas consumption, but anticipating energy transition scenarios in which distribution networks will also carry green gases and hydrogen, it can handle methane and hydrogen blends of up to 23 percent, placing it at the top end of the market.

Italgas has reported completion of the rollout of the first 20,000 units of its new next generation hydrogen ready gas smart meter. The company tested the technology in the field during 2024, prior to a widescale rollout across Italy starting in 2025. "With the installation of the first 20,000 Nimbus units, the energy transition towards green gas is further accelerated."

The large-scale installation of Nimbus, which will replace the phasing-out GPRS technology meters, is set to begin in 2025 and will also involve the new assets of 2i Rete Gas, reaching 6 million Nimbus by 2030.

The strategic purpose of this smart meter investment extends beyond operational efficiency. By installing hydrogen-compatible meters across its network, Italgas positions itself for whatever energy transition scenarios unfold. If hydrogen blending becomes widespread, Italgas's infrastructure will be ready. If biomethane takes off, the same metering technology can measure and manage those flows. The optionality is valuable regardless of which specific green gas pathway materializes.

The essential prerequisite to promote the development of renewable gases is the digital transformation of networks, enabling the creation of a smart, digital, and flexible network ready to accommodate and manage diverse gases such as biomethane, hydrogen, and synthetic methane. Guided by this vision, in Italgas we began the digital transformation of assets, processes and people already in 2017 and we continue to invest following a program that will soon lead us to become the first gas utility in the world with a fully digitized network.

VIII. INFLECTION POINT #4: Greek Expansion — DEPA Infrastructure (2022)

Italgas completed the acquisition of 100% of Depa Infrastructure S.A., Greece's leading gas distribution operator.

The Greek privatization agency and Hellenic Petroleum had agreed to sell DEPA Infrastructure for 733 million euros. DEPA Infrastructure holds stakes in Greece's three main gas distribution operators, which manage 7,500 km of gas network.

Greece represented a compelling strategic opportunity. The country was privatizing state assets as part of ongoing fiscal consolidation commitments. Its gas infrastructure was underdeveloped compared to Western Europe, creating substantial growth runway. And Greek government policy targeted coal and lignite phase-out, creating demand for natural gas as a transition fuel.

"We will put our experience and our technological know-how at the disposal of the country to build an infrastructure of excellence and with it contribute to achieving the coal and lignite phase-out targets set by the government, in line with those of the EU," Italgas CEO Paolo Gallo said.

Italgas aims to increase the number of gas users in Greece from approximately 600,000 at present to one million by 2028.

In February 2024, Italgas unveiled a new identity for its Greek operations. Italgas officially introduced the new identity of Greek companies, which are now named "Enaon", the holding company, and "Enaon Eda", the operating company. The establishment of Enaon and Enaon EDA represents a further step forward in the reorganization process undertaken by Italgas, marked by the merger of the previous three DSOs into one, which occurred in 2023.

The name Enaon draws inspiration from the Greek word Aenaos, which translates into "perennial" and "renewable" and which, associated with the world of energy, aims to represent a lasting offer, capable of satisfying current needs and the well-being of future generations.

Italgas has envisaged a total investment of €1 billion in Greece as part of the Group's 2024-2030 Strategic Plan. This program will be executed by its subsidiary Enaon, focusing on four main pillars to support Greece's ongoing ecological transition: Methanization of areas not yet connected to the gas distribution network and contributing to the phase-out of more polluting fuels like lignite and coal.

The digital transformation also includes replacing current traditional meters with Nimbus, the "H2 ready" smart meter, which guarantees the best performance in terms of remote management and remote reading, capable of managing mixtures of natural and renewable gas. The installation will begin as early as 2025 and will involve approximately 570,000 meters.

The Greek acquisition demonstrated Italgas's playbook: acquire underinvested infrastructure, apply the digital transformation expertise developed in Italy, and create value through operational excellence and network expansion. Enaon essentially became a case study in technology transfer—taking innovations developed for the Italian market and deploying them in a greenfield (or at least, under-digitized) environment.

IX. INFLECTION POINT #5: The 2i Rete Gas Mega-Deal (2024-2025)

If the Greek acquisition demonstrated Italgas's international ambitions, the 2i Rete Gas transaction represented the culmination of the company's Italian consolidation strategy.

With the Italgas-2i Rete Gas merger potentially reshaping the market by combining 55% of Italy's gas distribution, Ascopiave's targeted acquisitions could position it as a formidable regional player.

On October 5, 2024, Italgas announced a 5.3 billion euro deal, including debt, to buy 2i Rete Gas.

The consideration (equity value) of the transaction at closing – for 99.94% of the equity – was 2.0719 billion euros, based on the locked-box mechanism. 2i Rete Gas' net financial debt (excluding ex IFRS 16 impacts) as at 31 December 2024 was equal to 3.2 billion euros.

CEO Gallo framed the acquisition in historic terms: "The acquisition of 2i Rete Gas is history being fulfilled before our eyes."

But regulatory approval was not automatic. The transaction, involving the two largest natural gas distributors in Italy, was likely to harm competition. The transaction may well have led to competitive concerns with respect to future area-based tenders for the identification of gas distribution concession holders in 65 Italian minimum territorial areas (so-called ATEMs). Following a complex investigation, which saw the participation of numerous market players and industry associations, the Authority authorised the transaction subject to compliance with divestiture and behavioural measures.

The antitrust body called on Italgas to implement several remedies, including the sale of part of its gas distribution business in Italy corresponding to 600,000 customers from a total of 12.3 million clients the combined entity with 2i Rete Gas would have reached in its home country. The group will have to complete the disposal by the end of October 2025.

On April 1, 2025, Italgas closed the acquisition of 99.94% of the share capital of 2i Rete Gas from the sellers F2i and Finavias.

The integration moved remarkably quickly. The merger by incorporation of 2i Rete Gas into Italgas Reti, effective from 1 July 2025 and completed in just 90 days, enabled the integration of processes, the alignment of IT systems and the territorial reorganisation, generating the first synergies and efficiency gains from integration.

The Plan foresees cost synergies, operational efficiencies, and incremental revenues from digitalization investments amounting to approximately €280 million by 2030.

The 90-day integration timeline is extraordinary for a deal of this scale. It reflects years of preparation—Italgas had studied 2i Rete Gas extensively and planned the integration playbook long before closing. The digital infrastructure built through the DANA platform and Bludigit meant that IT system consolidation could proceed rapidly, unlike traditional utility integrations where legacy system incompatibilities create years of complexity.

Paolo Gallo emphasized: "We have created the European champion, the largest in size and the most advanced in terms of technology."

X. Current Strategic Vision & The Energy Transition

€15.6 billion of investment providing the country the European champion capable of building the gas industry of the future. These include the acquisition of 2i Rete Gas and the widespread application of AI – across gas, water, energy efficiency and information technology – which is expected to drive double-digit net income growth throughout the Plan period.

The 2024-2030 Strategic Plan represents the most ambitious investment program in the company's history. Italgas expects a cumulative RAB (Regulated Asset Base) for gas and water infrastructure in Italy and Greece to reach €18.2 billion by the end of 2030 (excluding ATEM tenders), nearly doubling compared to 2023. By 2030, Italgas also anticipates achieving revenues of €3.6 billion, with EBITDA and profit growing at an average annual growth rate (CAGR) of approximately 13%.

The energy transition thesis is central to this strategy. Through the REPowerEU plan, the EU has charted a course to achieve key objectives: diversifying energy sources, enhancing energy security, decarbonizing consumption, and boosting the economic competitiveness of businesses, with a focus on renewable gases (biomethane and hydrogen) and energy efficiency. By 2030, biomethane and hydrogen are expected to replace approximately 50% of Russia's share of natural gas imports in the EU—around 70 bcm of the 155 bcm imported in 2021.

This creates enormous infrastructure demand—and Italgas has positioned its network to capture it. Technological upgrades have enabled Italgas's networks to accommodate the distribution of alternative gases, including biomethane, synthetic methane, and hydrogen.

On sustainability, Italgas has established credibility with international bodies. For the fourth year in a row, Italgas has received the prestigious Gold Standard recognition in the An Eye on Methane 2024 report from the International Methane Emissions Observatory (IMEO). The report acknowledges Italgas's leadership role within the sector, driven by a proactive approach to emission reduction, not only within the company itself but also by encouraging best practices and offering mentorship to other industry operators. The An Eye on Methane 2024 report is based on data collected during the fourth year of the OGMP 2.0 program, the framework introduced by UNEP in 2020 for methane emissions reporting and monitoring.

Italy's Italgas carried out a comprehensive 2024 measurement campaign using advanced, vehicle-based leak detection technology across its entire gas distribution network. With higher frequency and broader coverage, the company has reduced methane leaks by over 40 percent since joining OGMP 2.0 in 2020.

The latest financial results demonstrate the strategy's execution. In 2024 Italgas confirmed its excellence in managing its businesses, recording 32 consecutive quarters of growth and accelerating the digital transformation of its infrastructure to support the energy transition.

The main economic and financial results from 2024 show continuous growth: adjusted EBITDA increased by 14.1%, rising to 1,350.9 million euros and Group adjusted net profit exceeded 500 million euros, up 15.2% compared to 2023.

With the 2i Rete Gas integration, 2025 results are showing even more dramatic improvement. In the first nine months of 2025, the Italgas Group recorded total revenues and other income adjusted of 1,800.5 million euros, up 37.5%, and adjusted EBITDA increased by 35.6% compared to the same period of the previous year, reaching 1,368.9 million euros. The Adjusted EBIT, amounting to 879.6 million euros, increased by 45.2% compared to the same period of 2024.

XI. Playbook: Business & Investing Lessons

↑ Back to Top

The Power of Regulated Monopolies

Italgas's durability across 188 years stems fundamentally from its concession-based business model. Gas distribution is a natural monopoly—duplicating pipes to serve the same customers makes no economic sense. Concessions grant exclusive rights within defined territories, creating predictable revenue streams protected from direct competition.

The ATEM tender system introduced "competition for the market" rather than "competition in the market"—operators compete periodically to win concessions, but once awarded, operate as local monopolies for 12-year periods. This framework rewards scale (larger operators have advantages in tender competitions), digital capability (can propose better services and pricing), and capital efficiency (RAB-based returns favor efficient investment).

↑ Back to Top

Digital Transformation in Legacy Infrastructure

Italgas demonstrates that "legacy" and "innovative" are not mutually exclusive. The company's digital journey—from cloud migration to DANA to Nimbus—transformed a centenarian utility into a technology leader.

Key success factors included: CEO commitment (Gallo made digital transformation the centerpiece of strategy), dedicated resources (Bludigit as a separate entity with its own P&L), willingness to develop proprietary solutions (rather than relying solely on vendors), and framing digitalization as an enabler of energy transition (not merely cost reduction).

The strategic lesson: technology leadership in "boring" industries can create substantial competitive advantages precisely because incumbents typically underinvest in innovation.

↑ Back to Top

M&A as Growth Engine

From early acquisitions like Napoletanagas (1982) through DEPA Infrastructure (2022) and 2i Rete Gas (2025), Italgas has used M&A systematically to build scale. The playbook involves: targeting underinvested assets, applying operational and digital expertise to extract value, achieving synergies through integration, and using enhanced scale to win future ATEM tenders.

The 2i Rete Gas deal exemplifies disciplined M&A execution: clear strategic rationale (European leadership), detailed integration planning (90-day merger completion), synergy realization roadmap (€280M by 2030), and regulatory navigation (accepted remedies to secure approval).

↑ Back to Top

Energy Transition Positioning

Perhaps most critically, Italgas transformed potential obsolescence risk (electrification rendering gas infrastructure stranded) into growth opportunity (hydrogen and biomethane distribution). This repositioning required:

• Reframing the narrative: from "natural gas distributor" to "energy transition enabler"
• Making infrastructure investments that create optionality (hydrogen-ready meters, digital networks capable of handling diverse gas blends)
• Building sustainability credentials (UNEP Gold Standard recognition)
• Advocating for policy frameworks that recognize gas infrastructure's transition role

Hamilton Helmer's 7 Powers Analysis

Examining Italgas through Hamilton Helmer's competitive strategy framework:

Scale Economies: Achieved through M&A—the combined Italgas/2i Rete Gas entity serves 12.9 million customers across 154,000 km of network, enabling cost efficiencies unavailable to smaller operators.

Network Effects: Limited in traditional sense, but digital infrastructure (DANA platform, smart meter network) creates data network effects—more connected points generate more operational intelligence.

Switching Costs: Extremely high. Replacing a gas distribution operator requires government intervention through the ATEM tender process. Customers have zero direct ability to switch.

Counter-Positioning: The digital transformation strategy represented counter-positioning versus traditional utilities—Italgas invested heavily in technology while competitors remained focused on conventional operations.

Cornered Resource: Concession portfolios represent a form of cornered resource—the right to serve specific territories cannot be replicated without winning tenders.

Process Power: The integration playbook (digital transformation methodology, integration processes that completed 2i Rete Gas merger in 90 days) represents embedded organizational capabilities.

Branding: Limited direct consumer branding (customers typically don't choose their gas distributor), but significant B2G (business-to-government) reputation for reliable investment and service quality.

↑ Back to Top

Porter's Five Forces

Supplier Power: Moderate. Italgas doesn't purchase the gas it distributes—that relationship is between customers and suppliers. For equipment and services, the company's scale provides bargaining power.

Buyer Power: Low. Municipalities grant concessions through ATEM tenders, but once awarded, customers have no alternative supplier. Pricing is regulated, limiting buyer influence.

Threat of Substitutes: This is the critical long-term risk. Electrification of heating and cooking could reduce gas demand. Italgas's response—positioning for hydrogen and biomethane—aims to ensure infrastructure remains relevant regardless of primary energy source.

Threat of New Entrants: Low for existing concessions (legal monopolies). For ATEM tender competitions, entry requires substantial capital and operational capabilities, favoring established players.

Competitive Rivalry: Concentrated post-2i Rete Gas acquisition. Among the possible buyers of divested activities are Ascopiave, Acea and Hera, two important Italian multiutilities. These represent the remaining meaningful competitors for future tenders.

Bull Case

• Hydrogen optionality: If hydrogen distribution scales significantly, Italgas's network and smart meters are ready. The company could capture substantial value from a transition that many still view as speculative.

• Italian consolidation runway: Despite the 2i Rete Gas acquisition, fragmentation remains. More than 200 companies still operate across the Italian market. ATEM tenders will continue driving consolidation, and Italgas is best positioned to win.

• Greek growth: Enaon's plan to expand Greek customers from 600,000 to 1 million+ represents visible, contracted growth through network expansion into underserved areas.

• Regulatory favorability: European energy security concerns (post-Ukraine invasion) have elevated gas infrastructure's strategic importance. Policy frameworks increasingly recognize gas as a transition fuel, supporting investment cases.

• Digital monetization: Bludigit's technology solutions are being deployed to external customers (Azerigas partnership, potential other international deals), creating a software/services revenue stream beyond distribution tariffs.

Bear Case

• Demand decline: Aggressive electrification policies could reduce gas volumes faster than hydrogen/biomethane can replace them. Distribution tariffs are partially volume-based—declining throughput pressures economics.

• Regulatory risk: ARERA sets allowed returns. Any downward revision in WACC (weighted average cost of capital) for regulated activities directly impacts profitability. The current regulatory period was extended through 2027, but future frameworks remain uncertain.

• Integration execution: The 2i Rete Gas integration is progressing well, but realizing €280M in synergies requires sustained execution over five years. Large integrations have historically disappointed.

• Capital intensity: €15.6B in planned investments requires substantial funding. While Italgas completed a €1.02B rights issue, leverage has increased materially post-acquisition. Rising interest rates could pressure returns on new investments.

• Antitrust constraints: Remedies required for the 2i Rete Gas approval limit future consolidation options. Winning additional ATEM tenders may face regulatory scrutiny given Italgas's dominant position.

Key KPIs to Monitor

1. RAB Growth: The Regulated Asset Base determines allowed returns under the tariff framework. Tracking RAB growth—organic (investment) plus inorganic (M&A)—provides visibility into future earnings power. Management targets €18.2B by 2030.

2. Digital Penetration: The percentage of network digitally monitored through DANA and percentage of smart meters installed (particularly Nimbus hydrogen-ready meters). These metrics indicate progress on the digital transformation thesis and hydrogen readiness optionality.

3. Concession Win Rate: Success in ATEM tender competitions validates the competitive positioning thesis. Tracking wins (and losses) in upcoming tenders reveals whether scale and digital advantages translate to market share gains.

XII. Conclusion: From Gas Lamps to Hydrogen Networks

In August 1837, Hippolyte Gautier couldn't have imagined that the gas lighting company he was chartering would still exist 188 years later—much less that it would operate smart meters capable of measuring hydrogen blends, employ artificial intelligence for network monitoring, and serve customers across multiple countries.

Yet Italgas's longevity makes a certain strategic sense. Infrastructure businesses that adapt to technological change rather than being displaced by it can compound value across extraordinary timeframes. Gas lighting gave way to electric lighting, but gas found new applications in heating and cooking. Manufactured town gas gave way to natural gas. And now, natural gas infrastructure is being positioned to carry hydrogen and biomethane—the energy carriers of a decarbonized future.

The key to this survival has been neither stubborn resistance to change nor chaotic reinvention, but rather thoughtful adaptation that leverages accumulated infrastructure assets while investing in capabilities for the next transition. The pipes laid by Gautier's workers in 1830s Turin are long gone, but the concession-based business model they established continues. The ENI-era methanization networks remain in service, now monitored by AI systems that would have seemed like science fiction to the engineers who designed them.

Paolo Gallo, the aeronautical engineer from Turin who took the helm in 2016, deserves substantial credit for the company's recent transformation. His vision of digital transformation as the "main enabler" of growth positioned Italgas as a technology leader rather than a legacy utility. The 2i Rete Gas acquisition—"history being fulfilled"—created European leadership. The Greek expansion demonstrated replicability beyond Italy's borders.

Whether this strategic positioning will prove prescient depends substantially on factors beyond Italgas's control: the pace of energy transition, regulatory frameworks for hydrogen distribution, and consumer and industrial acceptance of renewable gases. But by investing in hydrogen-ready infrastructure while those questions remain unresolved, Italgas has purchased valuable optionality.

For investors, Italgas represents a distinctive combination: the defensive characteristics of regulated infrastructure (predictable cash flows, limited competition, essential service) combined with energy transition growth optionality. The company that lit Turin's streets before Italy existed now aims to distribute the zero-carbon gases that will heat Italian homes long after fossil fuels have faded from the energy mix.

That continuity—across nearly two centuries, through technological disruptions, wars, nationalization, privatization, and now energy transition—represents the ultimate validation of infrastructure as a durable competitive advantage. The pipes change. The gases change. The technology changes. But the fundamental service—delivering energy to households and businesses through local networks—endures.
