Project finance and commodities offtake analyst

Long-term offtake secures demand for a material share of output.

The agreement commits Kimia to buy 23%–32% of annual production, capped at approximately 704,000 tonnes per year, on a take-or-pay basis. Take-or-pay structures typically reduce volume risk by requiring payment for contracted volumes, supporting bankability for project finance.

Key commercial terms include a ten-year initial term starting at ramp-up, pricing linked to CFR Brazil indexes with defined adjustments, and payment via cash‑against‑documents or standby letter of credit. These mechanisms align cash collection with shipment documentation and provide credit support options.

The contract permits assignment or pledging of receivables, which can facilitate financing once production commences. Actual impact depends on the final fixed percentage within the disclosed range and the project’s progress toward construction and commissioning as referenced in the company’s forward-looking statements.

Payments are to be made on a cash-against-documents basis unless Kimia provides and acceptable standby letter of credit from a top-rated financial institution.

The Agreement provides for customary provisions relating to performance reviews, take-or-pay penalties, product quality standards, force majeure, confidentiality, anti-corruption compliance, and termination rights. Either party may terminate the Agreement in limited circumstances, including insolvency, uncured material breach, frustration of purpose, or extended force majeure. PDB may assign or pledge receivables arising under the Agreement to finance project development.

Brazil Potash Corp. and PBF Participações Ltda. may provide support and guarantee undertakings under separate instruments as contemplated in the Agreement.
