Brazil Potash Reduces Upfront Capex with 28-Year Construction & Backup Power Contract

• A 20 MW modular diesel power plant is expected to supply electricity for the construction of two mine shafts, the processing plant, and the port/terminal until the grid connection line (SIN) is completed; it will then serve as a backup power system for 23 years once mining operations begin
• The agreement removes approximately $33 million of upfront power costs from the Autazes Project's construction budget and is expected to deliver approximately $10 million in net savings over the life of the contract
• Combined with the Company's offtake agreements covering approximately 91% of planned production and the recent enactment of Brazil's Profert program to support domestic fertilizer production, this agreement represents another step in advancing the Project's development and financing strategy
  

MANAUS, Brazil, Sept. 14, 2026 (GLOBE NEWSWIRE) -- Brazil Potash Corp. (“Brazil Potash” or the “Company”) (NYSE-American: GRO), a critical mineral exploration and development company advancing the Autazes Potash Project (the "Autazes Project" or "Project") in Amazonas State, Brazil, today announced that its wholly-owned Brazilian subsidiary, Potássio do Brasil Ltda., has signed a definitive agreement with Gera Center Amazônia Serviços e Locações De Máquinas e Equipamentos Ltda. (“Gera Center”), a Brazilian power generation company, for the implementation, operation and maintenance of a modular power plant for the Autazes Project. The agreement follows the non-binding memorandum of understanding announced in May 2026 and provides for a 28-year term: five years supplying power during construction, followed by 23 years as backup power once the mine is operating.

“Power is one of the most critical pieces of infrastructure for building and operating a mine in the Amazon, and this agreement represents an important step in securing the reliable power infrastructure required for the Autazes Project. By partnering with Gera Center under a Build-Own-Operate structure, we preserve construction capital for the mine while taking steps to ensure the Autazes Project has the reliable power it needs, both to build and for the life of the operation. This agreement is also part of our broader strategy to work with specialized infrastructure partners to reduce upfront capital requirements as we advance the Project toward construction," said Sergio Leite, President of Potassio do Brasil.

Why it matters for the Project

The Autazes site does not yet have access to Brazil's power grid. Under this agreement, Gera Center will supply and install diesel generators to power construction of the Project until the grid connection is completed, and that same equipment will later serve as backup power for the mine once a planned transmission line connects the site to the national grid (SIN).

Key terms

• Structure: A Build-Own-Operate (“BOO”) agreement. Gera Center funds, builds, owns and operates the plant for 28 years. The system will initially support Project construction and will subsequently operate in reserve mode as backup power.
• Equipment: 45 modular containerized diesel generators, reaching a peak capacity of 20 megawatts. Initial capacity will be 10 megawatts, increasing to 20 megawatts over the first year, with initial mobilization to be completed within 120 days following issuance of the Order to Proceed.
• Continuous Operation: Construction power (~5 years): During the continuous operation period, the agreement establishes contractual availability levels of at least 98% each month and 98.5% each year.
• Reserve Operation: Backup power (~23 years): Following the continuous operation period, the power generation system will transition to reserve operation to provide backup power for the Project.
• Cost impact: the agreement removes approximately $33 million of power-related spending from the Project's upfront construction budget (with a portion of Gera Center's cost recovery still occurring during the 5-year construction period) and is expected to deliver approximately $10 million in net savings over the life of the contract compared to earlier Project cost estimates.
  

This is one of several agreements Brazil Potash is pursuing to shift the cost of building infrastructure over to outside partners who fund, own and operate the equipment instead of the Company. The goal is to reduce how much Brazil Potash needs to raise and spend before the mine starts producing potash, thereby increasing equity investor returns, while still securing the reliable power the Project needs both to build and to run the mine long-term.

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, 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.
