The Mosaic Company is a leading producer and marketer of concentrated phosphate and potash crop nutrients, and a single-source supplier of phosphate- and potash-based crop nutrients and animal feed ingredients. It describes itself as the second largest integrated phosphate producer in the world, one of the largest producers and marketers of phosphate-based animal feed ingredients in North America and Brazil, and the leading fertilizer production and distribution company in Brazil. It is typically one of the top four global potash producers. The company accounts for roughly 10% of estimated global annual phosphate production and about 12% of global annual potash production. Mosaic is a Delaware corporation incorporated in March 2004 and was formed through the October 2004 combination of IMC Global Inc. and the fertilizer businesses of Cargill, Incorporated.
Mosaic reports three segments. The Phosphate segment sells phosphate-based crop nutrients and animal feed ingredients in North America and internationally, and accounts for about 72% of estimated North American production of concentrated phosphate crop nutrients. The Potash segment sells potash mainly as fertilizer, but also for industrial applications and, to a lesser degree, as animal feed ingredients, and accounts for about 34% of estimated North American potash production. The Mosaic Fertilizantes segment produces and sells phosphate- and potash-based crop nutrients and animal feed ingredients in Brazil. It has five phosphate rock mines and four chemical plants in Brazil, along with sales offices, blending and bagging facilities, port terminals and warehouses in Brazil and Paraguay. It also serves as a distribution outlet for the other two segments and accounts for about 73% of estimated Brazilian concentrated phosphate production. Corporate, Eliminations and Other includes intersegment eliminations, derivative and equity-security mark-to-market items (including the investment in Saudi Arabian Mining Company, Ma'aden), debt expenses, the China and India distribution businesses, and Mosaic Biosciences.
The company serves customers in approximately 40 countries, and its operations serve the four largest nutrient-consuming countries: China, India, the U.S. and Brazil. Its sales are made throughout North America and internationally.
Mosaic mines phosphate rock in Florida, Brazil and Peru and processes it into finished phosphate products in Florida, Louisiana and Brazil. It mines potash in Saskatchewan and New Mexico, and has other production, blending or distribution operations in Brazil, China, India and Paraguay. Its four material mining properties are Belle Plaine, Esterhazy, Florida and Tapira. Natural gas is among the raw materials used in production. The company operates through wholly- and majority-owned subsidiaries as well as businesses in which it holds minority or non-controlling interests. During 2025 it sold its idled Patos de Minas phosphate mining unit and its interest in the Taquari potash mine in Brazil, agreed to sell its Carlsbad, New Mexico potash mine, and completed a $900 million senior notes offering. Mosaic trades on the New York Stock Exchange under the symbol "MOS" and is headquartered in Tampa, Florida.
