Insights

Credit and capital structure analyst

Suzano secures long-dated, IPCA-linked funding in local markets.

Suzano has raised substantial local-currency funding with the settlement of R$2.5B in CPR-Fs and R$179M in simple debentures. Both instruments are long term, with final maturities between 2036 and 2041, which can help match funding tenor to asset lives.

The CPR-Fs and debentures carry fixed real interest rates of 7.0464%, 6.8338%, and 6.1759% per year, plus IPCA inflation adjustment. This structure ties cash flows to Brazilian inflation, which is common for domestic corporate debt and may reduce real value uncertainty in local terms.

The debentures qualify for the incentive under Law 12,431 because the underlying project is in a priority sector under Decree 11,964. That can broaden the investor base. Overall, this is a notable capital markets transaction but its net effect on leverage and cash flows will depend on how proceeds interact with Suzano’s broader balance-sheet strategy.
