ITAFOS AND RIO TINTO AMEND SULFURIC ACID CONTRACT TO FURTHER SUPPORT AMERICAN FARMING

HOUSTON, TX – May 14, 2026 – Itafos Inc. (TSX-V: IFOS) (OTCQX: ITFS) (the “Company” or “Itafos”) is pleased to announce that today

it has entered into an amendment to its sulfuric acid supply contract (the “Sulfuric Acid Supply Agreement”) with Rio Tinto, continuing its

long-term relationship with its U.S. copper producer Kennecott, a key supplier of a primary raw material required to produce its phosphate

products manufactured at the Company’s Conda, Idaho facility.

Pursuant to the amended Sulfuric Acid Supply Agreement, Itafos will continue to purchase sulfuric acid from the Kennecott mine in Utah.

Under the amended agreement, the reference index price will change from the Vancouver Index to the Tampa Index from May 1, 2026

through December 31, 2029. To promote long- term value for both U.S. farming and mining industries, the parties have agreed to a n

adjusted sulfuric acid price until December 31, 2029 to help address significant price volatility of sulfur over the last four years. Additional

modifications to the Sulfuric Acid Supply Agreement around delivered volumes have b een negotiated to provide greater flexibilit y for

incremental supply (subject to availability). Conda has historically sourced approximately 60% of its sulfuric acid requirements from Rio

Tinto, and it is expected that it will purchase similar volumes under the amended Sulfuric Acid Supply Agreement. After Decemb er 31,

2029, it is expected that Itafos will continue to purchase sulfuric acid from Rio Tinto.

Chief Executive Officer of Itafos, David Delaney commented, “We are pleased to announce this amendment and thank the Rio Tinto team

for further strengthening the relationship. The amended contract will allow us to maintain supply of a vital input to our production process

while decreasing our exposure to volatility in commodity prices . Rio Tinto has been a reliable supplier to the Conda plant for over three

decades, and we are pleased to continue this relationship on terms that are mutually beneficial to both parties.”

“This amended agreement reflects the strength of our long-standing partnership and our shared commitment to reliable supply for the

U.S. agriculture sector,” said Rio Tinto Kennecott Managing Director Nate Foster. “T hrough close collaboration, we are advancin g

solutions that strengthen domestic resili ency for American farmers while supporting the broader farming community to help keep crop

yields strong and supply as consistent as possible.”
