Italgas S.p.A.
Italgas owns and runs the gas pipes that carry natural gas into homes and businesses, and it also manages water services, earning a regulated fee for letting everyone use its network.
Italgas is the company that owns the pipes in the ground. When you turn on a gas stove or a boiler in Italy, the fuel usually travels through a network that Italgas built, maintains, and operates. The company doesn't sell you the gas itself — it earns a regulated fee for letting gas flow through its pipes, the way a toll road makes money from the cars that drive on it, not from the cargo inside.
That regulated setup is the heart of the business. A government authority sets how much Italgas can charge and what return it's allowed to earn on the money it invests in pipes and meters. That makes revenue predictable and steady, but it also means growth depends on expanding the network, upgrading it, and squeezing more efficiency out of it. The company has been replacing old metal pipes with modern plastic ones and rolling out smart meters that let it read usage remotely and spot leaks. Beyond gas, Italgas has moved into water services, running aqueducts and wastewater systems for towns and cities, which works on much the same regulated logic. The biggest shift came in 2025, when Italgas completed its takeover of 2i Rete Gas, a rival Italian gas distribution network, in a deal worth billions of euros. That purchase made Italgas the dominant gas distributor in Italy and significantly enlarged its customer base. The company also operates in Greece and a handful of other markets, giving it some exposure beyond its home country. Its main competitors in the gas and water network business are other regulated infrastructure operators, such as Enel through its grids arm and Snam, which owns much of Italy's gas transmission network — the big pipes that feed the smaller local networks Italgas runs.
Because the business is mostly regulated and capital-hungry, Italgas spends heavily on building and maintaining infrastructure, funded by a mix of debt and cash flow. It pays a steady dividend to shareholders and has used acquisitions like 2i Rete Gas to grow its asset base, which in turn grows the regulated return it's allowed to earn. The trade-off is that its fortunes are tied to regulators and to the pace of the energy transition: as Europe pushes toward electrification and renewable heating, the long-term role of gas networks is an open question, which is part of why moving into water makes strategic sense.
