Corporate finance and capital structure analyst

Suzano secures a large renewed revolving credit line, strengthening financial flexibility but not changing its core profile.

Suzano S.A. approved a new international revolving credit facility of up to US$ 1,800,000,000.00 with an initial five-year term, extendable twice for one year each. The facility will be contracted by wholly owned subsidiary Suzano International Finance B.V. or another subsidiary, backed by a full guarantee from the parent company.

This type of revolving credit facility typically serves as a liquidity backstop, supporting working capital, refinancing needs, or general corporate purposes, although specific uses are not detailed here. The Board also authorized the Vice-Presidency to execute derivative transactions tied to this facility strictly for hedging and without risk leverage, indicating a focus on managing currency or interest-rate exposure rather than speculative activity.

The decision centralizes authority in the Vice-Presidency to finalize documentation, guarantees, and related hedging instruments after the January 29, 2026 Board approval. Future disclosures in company filings may provide more detail on drawdowns, pricing, and how the facility fits into Suzano’s broader debt maturity profile.
