The Mosaic Company outlines its 2025 performance as a leading global producer of phosphate and potash fertilizers, serving about 40 countries with three main segments: Phosphate, Potash and Mosaic Fertilizantes in Brazil.
During 2025, Mosaic reshaped its asset portfolio, selling the idled Patos de Minas phosphate unit in Brazil for $111 million and recording a $94 million gain, while selling its interest in the Taquari potash mine for proceeds of up to $27 million and taking an impairment of about $66 million. It agreed to sell the Carlsbad, New Mexico potash mine for approximately $30 million, leading to an impairment of about $185 million.
The company also completed a $900 million bond offering, split between 4.350% notes due 2029 and 4.600% notes due 2030, and reports sizable market shares, including roughly 10% of global phosphate and 12% of global potash production. The filing details raw material dependencies, regulatory and trade risks, labor relations, human capital metrics and extensive global production and distribution capacities.
The Mosaic Company reported full year 2025 net income of $541 million, up from $175 million in 2024, and diluted EPS of $1.70. Adjusted EBITDA rose about 10% to $2.4 billion, driven mainly by stronger Potash pricing and volumes and higher margins in Mosaic Fertilizantes.
Results were marred by a fourth quarter 2025 net loss of $519 million (EPS of $(1.64)), largely from $422 million in pre-tax notable items including a $189 million Carlsbad asset impairment, $110 million of Mosaic Fertilizantes impairments, and various asset retirement and tax charges. Adjusted Q4 EPS was $0.22 and adjusted EBITDA was $505 million.
Cash flow from operations fell to $825 million in 2025 from $1.3 billion, as inventories and rock inputs increased, and free cash flow turned to $(535) million amid high capital expenditures of $1.36 billion. Mosaic plans about $1.5 billion of 2026 capex and targets additional $100 million of value capture versus 2025, while guiding to roughly 9 million tonnes of potash and at or above 7 million tonnes of phosphate production.
