SNAM SpA engages in the construction and management of gas infrastructures, through its subsidiaries. It operates through the following business segments: Natural Gas Transportation, Liquefied Natural Gas Regasification, Natural Gas Storage, and Natural Gas Distribution.

The Natural Gas Distribution segment operates on a concession scheme which distributes gas through local transportation networks from delivery points at the metering and reduction stations to the gas distribution network redelivery points at the end users.
