President Lula signs Profert into law, which combined with the previously announced SUFRAMA tax benefit has the potential to unlock meaningful construction cost savings and preferential government financing
Support builds on Brazil government's designation of potash being a critical-mineral and Autazes as a Project of National Importance
Brazilian courts have recently issued rulings favorable to the Autazes Project

MANAUS, Brazil, Sept. 10, 2026 (GLOBE NEWSWIRE) -- Brazil Potash Corp. ("Brazil Potash" or the "Company") (NYSE:GRO), a mineral exploration and development company advancing the Autazes Potash Project (the "Autazes Project" or "Project") in Amazonas State, Brazil, today announced a series of legal, legislative and engineering milestones achieved over recent months.

"We've been advancing the Autazes Project commercially, technically, and legally, and the developments of recent months have only added wind in our sails," said Matt Simpson, Chief Executive Officer of Brazil Potash. "Favorable rulings from Brazil's courts, the signing of Profert into law, and the award of our Front End Engineering Design packages all reinforce our steady momentum toward construction."

Recent 2026 Key Milestones:

Legislative & Financial Incentives

President Luiz Inácio Lula da Silva signed Profert (Pro-fertilizer legislation) into law without any vetoes, preserving its fiscal provisions exactly as approved by Congress. Combined with the Company's previously announced SUFRAMA benefit, Profert has the potential to unlock:

Meaningful potential construction cost reduction through production tax credits
BNDES-administered construction financing created to advance Brazil's critical minerals and fertilizer independence
A new domestic-content floor for fertilizer sold in Brazil, creating a built-in demand base for anticipated Autazes Project production, starting at 2% in 2027 and rising to 10% by 2037

The government has continued to signal support for the sector: on August 26, 2026, Vice President Geraldo Alckmin announced R$4 billion in additional BNDES-administered financing and working-capital support for Brazil's fertilizer industry as part of a broader R$18.5 billion package.¹

Legal & Regulatory

August 11, 2026: Brazil's Court of Appeal (TRF-1) blocked an appeal of legal challenges to the Autazes Project, preserving prior rulings that uphold the Project's environmental licenses and Indigenous consultation process
August 21, 2026: Brazil's Supreme Federal Court rejected a separate petition seeking to halt construction activities at the Autazes Project, leaving those favorable rulings, and the Project's current permits, fully in place

Engineering & Construction Readiness

Brazil Potash also advanced several fronts of construction readiness over the summer:

Initiated full-project FEED engineering coverage, awarding the mine shaft and underground development scope to WSP UK Ltd. and Redpath Deilmann, joining Wood and Promon Engenharia on surface facilities, with completion targeted for early Q2 2027, a key prerequisite for construction debt financing
Commenced on-site training programs, building workforce momentum ahead of anticipated construction
Advanced geotechnical drilling arrangements critical to finalize the shaft sinking design
Received BOOT proposals covering all envisaged construction power
Hosted additional investor site visits and continued third-party construction debt diligence

"Each milestone removes a layer of risk from the Project," added Simpson. "We look forward to sharing updates as we continue advancing the Autazes Project."

About Brazil Potash

Brazil Potash (NYSE: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, with among the highest amounts of fresh water and arable land and an ideal climate for year-round crop growth, yet the country imported approximately 96% of the potash it consumed in 2025 despite hosting what is anticipated to be one of the world's largest undeveloped potash basins. 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.
