Approved Buyback May Inject Up to R$ 16 Billion
On Monday, October 6, 2025, Vale (VALE3) approved an offer to repurchase 100% of its participative debentures from the 6th issuance.
The fixed price was R$ 41.92 per bond, a value that includes a premium of 52,400% over the original nominal value.
These securities were trading in the market for around R$ 36, with approximately 388.6 million units outstanding, according to data from Anbima.
If all holders participate, the operation could reach around R$ 16 billion in total disbursement.
Historical Context and Structure of the Debentures
The participative debentures, issued in 1997 for R$ 0.01, offer variable returns based on revenue from iron ore, copper, and gold.
The remuneration is 1.8% on part of the iron revenue and 2.5% on copper and gold. Calculated in dollars and paid in reais, the current yield hovers around 13% per year.
With the production cap reached in the Southeast in 2025, costs have increased, making the buyback more advantageous for Vale.
Vale’s Strategy: Reduce Costs and Simplify Liabilities
The company interprets the buyback as a strategic measure to reduce financial costs and optimize its capital structure.
The move also eliminates burdensome liabilities, reinforcing Vale’s focus on operational efficiency and financial discipline.
The operation signals to the market that the company seeks to strengthen its credit profile and ensure predictability in future obligations.
Financial institutions such as Citi, Bradesco BBI, BTG Pactual, Itaú BBA, and Santander participate as structuring agents for the buyback.
This joint effort increases the credibility of the process and facilitates the engagement of interested investors.

Timeline and Participation in the Offer
The deadline for participation in the buyback ends at 7:20 PM on October 31, 2025, Brasília time. Meanwhile, Vale informed that the financial settlement of the operation should occur on November 5, 2025.
Additionally, the company ensured that it will comply with all applicable regulations during the process and will maintain full transparency at each stage.
Finally, the participation procedure requires the delivery of eligible bonds and the receipt of payment only after the settlement date.
Risks, Criticisms, and Transparency in the Operation
Some analysts point out that the buyback, although voluntary, may favor Vale, especially in the face of investors who cannot adhere to the proposal within the determined timeframe.
Moreover, since 2021, there have been questions about adequate compensations, as the original deeds did not foresee a mandatory buyback right, which generates debates in the market.
Still, the market assesses the initiative as positive, because it reduces the company’s exposure to high-cost liabilities, strengthening its financial position.
In this way, experts note that Vale seeks to reinforce its corporate governance and, at the same time, align its practices with the best international standards, consolidating its image of transparency and solidity.
