Material Changes vs. Prior Period
- Revenue Growth: Net sales increased 8% to $12.1 billion, driven by higher average selling prices across all segments, partially offset by lower sales volumes in the Phosphate segment.
- Profitability Surge: Net earnings attributable to Mosaic increased 209% to $540.7 million. This was significantly aided by a $271.7 million foreign currency transaction gain (vs. a $685.8 million loss in 2024) and a $317.0 million unrealized mark-to-market gain on Ma'aden equity investment.
- Impairments and Asset Sales: The company recorded a $99.9 million goodwill impairment (primarily in Mosaic Fertilizantes) and a $157.3 million loss on assets sold and to be sold. Notable transactions included:
- Carlsbad Mine (NM): Agreed to sell for ~$30 million; recorded a $185.0 million impairment loss as assets are held for sale.
- Taquari Mine (Brazil): Sold for up to $27 million; recorded a $66 million impairment loss.
- Patos de Minas (Brazil): Sold for $111 million; recorded a $94 million gain.
- Segment Performance:
- Phosphate: Operating earnings declined to $135 million (from $225 million) due to higher sulfur/ammonia costs and lower volumes, despite higher selling prices.
- Potash: Operating earnings increased to $638 million (from $605 million) driven by higher prices and volumes, offset by the Carlsbad impairment.
- Mosaic Fertilizantes: Operating earnings increased to $277 million (from $238 million) due to higher selling prices, though Q4 margins were pressured by sulfur costs and credit constraints in Brazil.
Guidance, Outlook, and Risks
- Capital Allocation: The company expects capital expenditures of approximately $1.5 billion in 2026. It maintains a target liquidity buffer of up to $3.0 billion.
- Debt Financing: In November 2025, Mosaic completed a $900 million public bond offering ($500 million due 2029 at 4.350% and $400 million due 2030 at 4.600%).
- Key Risks:
- Raw Material Costs: Volatility in sulfur and ammonia prices significantly impacts margins, particularly in the Phosphate and Brazil segments.
- Regulatory & Environmental: Significant exposure to environmental regulations, including Asset Retirement Obligations (AROs) totaling $2.6 billion. Ongoing legal proceedings regarding countervailing duties on phosphate fertilizers from Morocco and Russia.
- Geopolitical & Trade: Risks related to U.S. tariffs on Canadian potash and retaliatory tariffs, as well as political instability in Brazil and Peru.
- Weather & Climate: Operations are susceptible to hurricanes (Florida/Louisiana) and drought conditions affecting river transport and crop demand.
Investor Verification Checklist
- Asset Sales Closure: Verify the closing of the Carlsbad, New Mexico potash mine sale in H1 2026 and the final proceeds received.
- Raw Material Hedging: Review the effectiveness of hedging strategies for sulfur and ammonia given the significant cost increases in 2025.
- Goodwill Impairment: Monitor the Mosaic Fertilizantes reporting unit for further impairment risks given the $96.3 million charge in 2025.
- Environmental Liabilities: Track the status of the New Wales Phase II stack repairs and the associated $65.1 million reserve.
- Foreign Currency Exposure: Assess the sustainability of the $271.7 million foreign currency gain, which was a major driver of 2025 net income.
- Trade Policy: Monitor developments regarding U.S. tariffs on Canadian potash and countervailing duty orders on Moroccan/Russian phosphate.
