Insights

Cross-border corporate governance analyst

Braskem details a sizable, arms-length steam supply deal with related-party Petrobras.

Braskem is entering a multi‑year steam supply contract with Petrobras/FAFEN, estimated at R$ 161.5 million from February 1, 2026 through December 13, 2030. Volumes are set at 240 tons per day, with some flexibility via advance revision of the flow rate.

Governance-wise, Petrobras is a shareholder with significant influence, so the disclosure emphasizes that Petrobras and its managers did not take part in Braskem’s internal decisions or negotiations. Management also asserts pricing is aligned with market conditions and that the contract reflects products with positive margins for Braskem.

The contract includes automatic termination for breaches, including anti‑corruption and confidentiality provisions, and if Petrobras resells steam without authorization. Future filings may show how this long‑term utility arrangement contributes to Braskem’s operating margins and capacity utilization over the contract period.
