Decision leaves in place favorable rulings previously issued by Brazil’s federal Court of Appeals
Court-supervised consultation process with the Mura people resulted in more than 90% support for the Autazes Project, owned by Brazil Potash

MANAUS, Brazil, Aug. 21, 2026 (GLOBE NEWSWIRE) -- Brazil Potash Corp. ("Brazil Potash" or the "Company") (NYSE:GRO), a mineral exploration and development company with a critical mineral potash agriculture project, the Autazes Potash Project (the "Autazes Project"), today announced that, further to the Company’s press release dated July 16, 2026, Brazil’s Supreme Federal Court (Supremo Tribunal Federal or "STF"), the country’s highest court, has rejected a petition that sought, among other relief, to halt construction permits and other development activities at the Autazes Project.

The petition, filed by Brazil's Federal Public Defender's Office (Defensoria Pública da União, or "DPU"), sought to suspend the effects of favorable decisions previously issued by Brazil’s Federal Court of Appeals. On August 18, 2026, the President of the STF, Justice Edson Fachin, reject the petition in full.

In his decision, Justice Fachin found that the requirements for this exceptional type of proceeding had not been met, including because there was no demonstrated serious harm to public order or the economy. The decision also noted that such proceedings cannot be used as a substitute for the appropriate appellate process.

With this decision, the Court of Appeal’s favorable rulings remain in effect, and the petition does not affect the current status of the Autazes Project’s licensing or ongoing development activities. The Company remains committed to the responsible and transparent development of the Autazes Project, in compliance with applicable environmental, social and legal requirements, and views today's decision as a positive step in the continued advancement of the Project.

About Brazil Potash

Brazil Potash (NYSE-American: GRO) (www.brazilpotash.com), through its subsidiary Potássio do Brasil, is developing the Autazes Project to supply potash 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 approximately 97% of its potash fertilizer in 2025, 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.
