The Foz do Amazonas Basin, a
oil province spanning Brazil’s equatorial margin, has long been a holy grail for Petrobras. With reserves potentially rivaling Exxon’s Guyana fields, the region’s deepwater resources could redefine Brazil’s energy future—and Petrobras’ stock. But for years, the project’s progress has been stifled by regulatory hurdles and environmental opposition. Now, a confluence of events—the approval of Petrobras’ fauna emergency plan, the mobilization of its ODN-II drillship, and the looming Pre-Operational Assessment (APO)—positions the company to finally unlock this prize. For investors, the question is clear: Is the regulatory finish line in sight, and can the payoff justify buying now?
In April 2025, Brazil’s environmental agency Ibama granted preliminary approval to Petrobras’ fauna emergency plan, a critical step toward final environmental licensing. This plan aims to mitigate risks to the region’s biodiversity in case of an oil spill, addressing concerns raised by Ibama’s technical teams and independent studies. While simulations of spill trajectories and wildlife rescue protocols are still pending, this approval breaks a years-long impasse.
The APO—a mandatory test of Petrobras’ spill response capabilities—is now the final hurdle. To execute it, the company must secure Ibama’s green light by May 15, 2025, to deploy the ODN-II drillship from Guanabara Bay to the Foz do Amazonas Basin. This vessel, retrofitted to prevent invasive species contamination, is the linchpin of the assessment. A delayed approval or rejection here could stall the project indefinitely, but a green light would clear the path for drilling in Block FZA-M-059—a reserve Petrobras estimates holds 1.2 billion barrels of recoverable oil.
Petrobras’ stock has lagged peers amid regulatory uncertainty, but a positive APO outcome could catalyze a rerating.
The APO’s timeline is a binary event with outsized implications. Success here would:
1. Validate Petrobras’ environmental commitments, silencing critics who argue spills could devastate mangrove ecosystems and Indigenous lands.
2. Unlock $78 billion in exploration investments pledged under Petrobras’ 2023–2027 strategic plan, redirecting capital toward high-margin Equatorial Margin reserves.
3. Preempt competition, as rivals like Shell and Brava Energia eye the same basin. Petrobras’ first-mover advantage could secure its position as Brazil’s deepwater king.
Analysts estimate that full production from Foz do Amazonas—expected to begin by 2027—could add 150,000 barrels per day to Petrobras’ output, boosting its EBITDA by 10–15%. This is a game-changer for a company currently trading at 5.2x EV/EBITDA, a discount to peers like Exxon (8.5x) and Chevron (10.1x).
Opposition remains fierce. Indigenous groups like the Uaçá Karipuna and environmental NGOs continue to challenge the project’s social and ecological risks. Meanwhile, Ibama’s technical teams have twice rejected the project since 2023, citing inadequate safeguards. However, political momentum is shifting: Brazil’s Lula administration, while pro-environment, has prioritized oil revenue to fund its social programs.
Petrobras’ RRR has lagged due to exploration delays, but Foz do Amazonas success could reverse this trend.
Petrobras’ shares are a paradox. Despite holding one of the world’s largest untapped oil basins, the stock trades at a discount that ignores its growth potential. Key metrics:
- Undiscovered resource upside: The Equatorial Margin could add 10 billion barrels, per Petrobras’ estimates.
- Cost efficiency: Deepwater drilling in the region leverages Brazil’s pre-salt expertise, with break-even costs ~$40/barrel.
- Dividend resilience: Even with modest production growth, Petrobras’ $30 billion annual capex allows for ~5% dividend yield, a rare combination in energy.
A positive APO outcome could narrow Petrobras’ valuation gap with peers, potentially lifting the stock by 20–30%. Even a partial rerating would make this a standout play in an oil sector hungry for growth.
The May 15 deadline is a make-or-break moment. With the ODN-II mobilization request pending, investors have a narrow window to position ahead of the news. Even a delayed approval could see the stock stabilize as the APO process unfolds.
For bulls, the math is compelling: Petrobras’ downside is limited by its $80 billion cash flow from existing operations, while upside is asymmetric if Foz do Amazonas clears regulatory hurdles. This is a buy the dip opportunity—a chance to own a potential turnaround story at a fraction of its true value.
In a market starved for energy growth stories, Petrobras’ Amazonas breakthrough is no longer a “what if.” It’s a “when.” Investors who bet on the APO’s success now could reap the rewards of a long-awaited Petrobras renaissance.

Final Call: Buy PETR4 before May 15. The regulatory finish line is in sight—and the payoff could be historic.
