The long-term value of Brazil's state-controlled oil giant, Petrobras, is increasingly tied to the politically and environmentally sensitive Foz do Amazonas exploration area, with one bank estimating the development is worth $15.9 billion. A recent report from Scotiabank analysts Jorge Gabrich and Pedro Nascimento concluded that successful development of the region's northwest portion alone has a Net Present Value (NPV) of $15.9 billion, a value that could add approximately 14% to Petrobras's current valuation, or R$ 6.65 per share. The report emphasizes that for Petrobras, decisions about the Foz do Amazonas are strategically more critical than election results, as the area is vital for maintaining the company's production levels in the next decade.
