Brazil Potash Provides Update on Autazes Project Regarding Brazilian Court Filing

Brazil Potash Corp. (“Brazil Potash” or the “Company”) (NYSE-American: GRO), a mineral exploration and development company advancing the Autazes potash project in Amazonas State, Brazil (the “Autazes Project” or the “Project”), is providing the following update regarding a recent procedural filing in the Brazilian courts relating to the Project.

Overview of the Filing The Company has become aware, through publicly available court records, that the Brazilian Federal Public Defender’s Office (Defensoria Pública da União or “DPU”), acting on behalf of certain indigenous organizations opposed to the Project, has filed a Suspensão de Tutela Provisória (an application to suspend provisional relief) directly with the President of the Brazilian Supreme Federal Court (Supremo Tribunal Federal or “STF”). The Company has not yet been formally served with the filing.

The application is not a new lawsuit and does not introduce any new allegations or new underlying facts. It is a procedural request within the scope of an existing Public Civil Action that was originally filed by the Brazilian Federal Public Prosecutor’s Office in December 2016 and has been the subject of extensive litigation over the past several years. The application seeks to overturn recent decisions of the Federal Regional Court of the First Region (“TRF-1”) that were issued in favor of the Company and the Indigenous Mura Council (Conselho Indígena Mura or “CIM”), and to suspend installation activities related to the Project.

Favorable Judicial Record The issues raised in the DPU’s application have been extensively litigated before the Brazilian federal courts and the TRF-1 has previously issued multiple favorable decisions recognizing, among other things, (i) the legitimacy of the CIM as the representative organization of the Mura indigenous communities in the municipality of Autazes, (ii) the conformity of the indigenous consultation process with the requirements of United Nations International Labour Organization Convention No. 169 based on a consultation protocol developed by the Mura communities under judicial supervision, and (iii) the validity of the free, prior and informed indigenous consultation, authorizing the continuation of the environmental licensing process for the Autazes Project. The consultation was conducted over a period of more than six years, involved over 35 indigenous villages, and culminated in an assembly in which approximately 90% of the participating communities voted in favor of the Project’s continuation.

On July 9, 2026, the Office of the Prosecutor General of Brazil (Procuradoria-Geral da República or “PGR”), the highest authority of the Federal Publico Prosecution Office before the STF, issued a formal opinion (parecer) in connection with the DPU’s filing, recommending that the application not be heard on the merits. The PGR concluded that the DPU lacks standing to file the application and that the procedural vehicle is unsuitable for reexamination of facts and evidence — a position consistent with the Company’s assessment of the filing.

Company Response The filing does not change the legal status of the Autazes Project or any of the Company’s existing environmental licenses, which remain in full force and effect. Brazil Potash, together with its external Brazilian counsel, is evaluating the filing and preparing its response. The Company intends to vigorously defend its position and continues to believe that its legal position is well supported by the existing judicial record, the multiple favorable decisions previously issued by the TRF-1, and the PGR’s recommendation that the application not be heard. The Company considers this filing to repr...
