MOSAIC CO

We are exposed to the impact of fluctuations in the relative value of currencies, fluctuations in interest rates, fluctuations in the purchase prices of natural gas, nitrogen, ammonia and sulfur consumed in operations, and changes in freight costs, as well as changes in the market value of our financial instruments. We periodically enter into derivatives in order to mitigate our interest rate risks, foreign currency risks and the effects of changing commodity prices and freight prices, but not for speculative purposes. Unrealized mark-to-market gains and losses on derivatives are recorded in Corporate, Eliminations and Other. Once realized, they are recorded in the related business segment.

Foreign Currency Exchange Rates

Due to the global nature of our operations, we are exposed to currency exchange rate changes, which may cause fluctuations in our earnings and cash flows. Our primary foreign currency exposures are the Canadian dollar and Brazilian real. To reduce economic risk and volatility on expected cash flows that are denominated in the Canadian dollar and Brazilian real, we use financial instruments that may include forward contracts, zero-cost collars and/or futures.

The functional currency of several of our Canadian entities is the Canadian dollar. For those entities, sales are primarily denominated in U.S. dollars, but the costs are paid principally in Canadian dollars. In July 2025, we discontinued hedging Canadian dollar transactions. As of December 31, 2025, we continue to have open hedges remaining from the previous hedging program when we hedged cash flows on a declining basis, over 12 months. A stronger Canadian dollar generally reduces these entities’ operating earnings. A weaker Canadian dollar has the opposite effect. Depending on the underlying exposure, such derivatives can create additional earnings volatility because we do not apply hedge accounting. Gains or losses on these derivative contracts, both for open contracts at quarter-end (unrealized) and settled contracts (realized), are recorded in either cost of goods sold or foreign currency transaction gain (loss).

The functional currency of our Brazilian subsidiaries is the Brazilian real. We finance our Brazilian inventory purchases with U.S. dollar-denominated liabilities. We hedge the net Brazilian real exposure of our inventory production activities for up to four months, covering the operational cycle of the business. A strengthening of the Brazilian real relative to the U.S. dollar

F- 20 has the impact of reducing these liabilities on a functional-currency basis. When this occurs, the related foreign currency transaction gain is recorded as non-operating income. A weakening of the Brazilian real generally has the opposite effect.

As discussed above, we have Canadian dollar, Brazilian real and other foreign currency exchange contracts. As of December 31, 2025 and 2024, the fair value of our major foreign currency exchange contracts was an asset of $1.0 million and a liability of $82.6 million, respectively. We recorded an unrealized gain of $83.4 million in cost of goods sold and recorded an unrealized loss of $4.2 million in foreign currency transaction gain (loss) in the Consolidated Statements of Earnings for 2025.

Commodities

We use forward purchase contracts, swaps and occasionally three-way collars to reduce the risk related to significant price changes in our inputs and product prices.

All gains and losses on commodities contracts are recorded in cost of goods sold in the Consolidated Statements of Earnings.

As of December 31, 2025 and 2024, the fair value of our major commodities contracts was ($0.4) million and ($1.8) million, respectively. We recorded an unrealized gain of $1.3 million in cost of goods sold in the Consolidated Statements of Earnings for 2025.

Our primary commodities exposure relates to price changes in natural gas.

Interest Rates

From time to time, we enter into interest rate swap agreements to hedge our exposure to changes in future interest rates related to anticipated debt issuances. At December 31, 2025 and 2024, we had no interest rate swap agreements in effect.

Summary

Overall, there have been no material changes in our primary market risk exposures since the prior year. In 2026, we do not expect any material changes in our primary risk exposures.
