NTS was created from a Statement of Commitment signed with the Brazilian National Petroleum, Natural Gas and Biofuels Agency (“ANP”), in which Petrobras has committed to restructure the Transportadora Associada de Gás (TAG) and its wholly-owned subsidiaries, in order to create a natural gas carrier in southeastern Brazil (NTS) and another in the North-Northeast (NTN).

On April 4, 2017, Petrobras concluded the sale of 90% of its shares in NTS to Nova Infraestrutura Fundo de Investimentos em Participações Multiestratégia (“FIP”), managed by Brookfield Brasil Asset Management Investimentos Ltda., a company affiliated to Brookfield Asset Management. On the same date, the FIP conducted the sale of part of its shares in NTS to Itaúsa S.A.

On April 30, 2021, Nova Infraestrutura Gasodutos Participações SA (NISA), a company whole owned by the current controlling shareholders of the Company, FIP and Itaúsa, concluded the purchase of the entire remaining Petrobras stake in NTS, corresponding to 10% of the shares.
