Brazil Potash (NYSE American: GRO) outlines status of Autazes court challenge

Rhea-AI Filing Summary

Brazil Potash Corp. reported a procedural development in long‑running Brazilian litigation over the Autazes potash project. Brazil’s Federal Public Defender’s Office (DPU), acting for indigenous organizations opposed to the project, filed a “Suspensão de Tutela Provisória” with the President of the Supreme Federal Court, seeking to overturn recent Federal Regional Court (TRF‑1) decisions favorable to Brazil Potash and the Indigenous Mura Council and to suspend installation activities. The company states this is not a new lawsuit and introduces no new facts, but remains within an existing Public Civil Action begun in 2016.

Brazil’s Prosecutor General (PGR) issued a formal opinion on July 9, 2026 recommending the application not be heard, concluding the DPU lacks standing and that the procedure is unsuitable for reexamining facts and evidence. Brazil Potash says the filing does not change the legal status of the Autazes Project or its environmental licenses, which remain in full force and effect, and it is preparing a response while relying on its prior favorable court decisions and the PGR opinion.

Suspensão de Tutela Provisória regulatory

"has filed a Suspensão de Tutela Provisória (an application to suspend provisional relief)"

Suspension of provisional relief is a court decision that temporarily halts a previously granted interim measure—such as an injunction, asset freeze, or temporary enforcement order—so that the measure’s effects are paused while the legal process continues. For investors, this matters because it can immediately change a company’s operational or financial exposure, like unfreezing funds or allowing halted activities to resume, altering near-term legal risk and business continuity.

Public Civil Action regulatory

"within the scope of an existing Public Civil Action that was originally filed"

A public civil action is a lawsuit filed to protect collective or public interests—such as consumer rights, the environment, or public health—often brought by a government agency, public prosecutor, or an authorized citizen group. Think of it like a neighborhood or city suing a company on behalf of many people rather than one individual; outcomes can include fines, cleanup orders, or injunctions that can affect a company’s costs, operations, and reputation, so they are material to investors.

environmental licensing process regulatory

"authorizing the continuation of the environmental licensing process for the Autazes Project"

free, prior and informed indigenous consultation regulatory

"the validity of the free, prior and informed indigenous consultation, authorizing the continuation"

A legal and ethical process requiring that Indigenous peoples are consulted without coercion, before decisions are made, and with full, accessible information about projects or policies that may affect their lands, rights, or livelihoods. Like asking a neighborhood for input and sharing all the facts before building a road, it matters to investors because it can affect project timelines, regulatory approvals, legal risks and the social acceptance that influences whether a project can proceed.

greenhouse gas emissions technical

"mitigating approximately 1.4 million tons per year of GHG emissions"

Greenhouse gas emissions are the gases a company releases into the air—like carbon dioxide or methane—that trap heat in the atmosphere and contribute to global warming. For investors, these emissions matter because they can lead to higher regulatory costs, fines, shifting consumer preferences, and physical risks (like supply-chain disruptions), or create opportunities in low-carbon products; think of emissions as a company’s climate footprint that can affect future profits and value.

Brazil Potash Provides Update on Autazes Project Regarding Brazilian Court Filing

MANAUS, Brazil, July 16, 2026 (GLOBE NEWSWIRE) — 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 represent another procedural development within existing litigation, rather than a new legal proceeding or a new substantive challenge to the Project. Brazil Potash will provide further updates as warranted.

About Brazil Potash

Brazil Potash (NYSE-American: GRO) (www.brazilpotash.com) is developing the Autazes Project to supply sustainable fertilizers to one of the world’s largest agricultural exporters. Brazil is critical for global food security as the country has amongst the highest amounts of fresh water, arable land, and an ideal climate for year-round crop growth, but it is vulnerable as it imported over 95% of its potash fertilizer in 2021, despite having what is anticipated to be one of the world’s largest undeveloped potash basins in its own backyard. The potash produced will be transported primarily using low-cost river barges on an inland river system in

partnership with Amaggi (www.amaggi.com.br), one of Brazil’s largest farmers and logistical operators of agricultural products. With an initial planned annual potash production of up to 2.4 million tons per year, Brazil Potash’s management believes it could potentially supply approximately 20% of the current potash demand in Brazil. Management anticipates 100% of Brazil Potash’s production will be sold domestically to reduce Brazil’s reliance on potash imports while concurrently mitigating approximately 1.4 million tons per year of GHG emissions.
