Petróleo Brasileiro S.A. - Petrobras (PETR4.SA) Stock Analysis & Winston Score
Petrobras is Brazil's national oil and gas company, owned mostly by the Brazilian government. It finds oil underground, pulls it out of the ocean, refines it into fuels like gasoline and diesel, and sells those fuels to businesses and consumers across Brazil. The company is one of the world's leading deepwater oil producers, operating massive offshore fields in the pre-salt layer beneath the Atlantic Ocean. Petrobras earns money by selling crude oil, refined fuels, and natural gas, mostly within Brazil but also to international buyers. It is enormous, generating over $100 billion in annual revenue, and its control of Brazil's largest refineries and pipelines gives it a strong domestic advantage that is hard for competitors to replicate. The biggest risk the company faces is political interference — because the Brazilian government controls it, decisions about pricing, dividends, and investment can shift based on politics rather than pure business logic.
