Insights

Fixed-income and ESG-focused analyst

Suzano structures a R$2.5B rural notes deal earmarked for forestry projects.

Suzano plans to issue CPR-Fs totaling R$2,500,000,000.00, split between two series using a bookbuilding process with professional investors under Brazilian CVM rules. This diversifies its funding through rural product notes, a structure linked to agribusiness and forestry activities.

The company states that net proceeds will finance homogeneous forest formation and exploitation and conservation of native forests, tying the funding directly to core operations with an environmental dimension. Actual issuance volume per series will depend on investor demand identified in the bookbuilding.

Completion of the offering is explicitly conditioned on market conditions and regulatory and contractual compliance, so the timing and final allocation between series remain open. Further company and CVM website postings are expected to detail execution progress as the CPR-Fs Offering advances.
