Oil Price Volatility Risk: Fluctuations in global oil and gas prices directly impact PBR's revenues, profitability, and investment capacity, making financial planning challenging.

Political and Regulatory Interference Risk: As a state-controlled entity, PBR is highly susceptible to government intervention, including pricing policies, fuel subsidies, and strategic decisions that may not align with commercial interests.

Environmental and Climate Change Compliance Risk: Increasing global pressure for decarbonization, stringent environmental regulations, and the transition to cleaner energy sources pose significant long-term risks to PBR's traditional business model and require substantial investment in compliance and adaptation.
