Risk Factors
- CVD orders on Moroccan/Russian phosphate imports under DOC review; reversal could restore unfair competition harming U.S. phosphate business
- 25% U.S. tariff on Canadian potash imposed March 2025; temporary USMCA exemption exists but reintroduction risk remains material
- Sulfur supply dependent on North American oil refinery operating rates; reduced refinery output directly cuts phosphate production inputs
- ~64% of net sales from outside U.S.; Brazilian real and Canadian dollar volatility create structural currency mismatch on USD-denominated liabilities
- State-owned competitors (Morocco, Russia, Belarus, China) subsidized via lower-cost gas, mining rights, and tax incentives, creating structural cost disadvantage
Business Overview
- World's leading phosphate/potash producer; three segments (Phosphate, Potash, Mosaic Fertilizantes) serving ~40 countries

- 13,249 total employees; pay equity audit revealed only 0.5% outliers requiring compensation adjustments in 2026 cycle
Management Discussion & Analysis
- Revenue $12.05B, up $929.6M (+8%) YoY; prior year $11.1B fell 19% from $13.7B in 2023
- Gross margin 15.8% vs 13.6% prior year; operating margin improved as operating earnings rose to $821.5M from $621.5M
- Best segment: Potash, operating earnings $638M vs $605M, gross margin 32.7% vs 26.9%; worst: Phosphate, operating earnings $135M vs $225M, gross margin 9.6% vs 13.1%
