MILAN, March 22 (Reuters) - Italy's second-largest gas distributor 2i Rete Gas said on Friday its adjusted core profit rose 9.2% last year, as the group is working for an initial public offering on the Milan bourse.

2i Rete Gas, which is controlled by Italian infrastructure fund F2i, said its adjusted earnings before interest, taxes, depreciation and amortisation (EBITDA) rose to 546 million euros ($591 million) last year.

The group, which competes with Italgas, posted adjusted revenue of 815 million euros in 2023, up 11.7%.

According to sources, the gas distributor is seeking to sell around 600 million euros worth of its shares in what would be one of Italy's biggest IPOs this year.

2i Rete Gas' net debt rose slightly to 3.2 billion euros at the end of December. ($1 = 0.9246 euros) (Reporting by Elisa Anzolin, editing by Gianluca Semeraro and Tomasz Janowski)
