The Mosaic Company reported a net loss of $258 million for the first quarter of 2026, with diluted earnings per share of negative $0.81 and adjusted EBITDA of $416 million. The Tampa, Florida-based fertilizer producer cited higher unit production costs in its phosphate business as the primary driver of the loss, following a supply disruption to key raw material inputs linked to instability affecting US-Iran relations.
Mosaic's phosphate production operations in the United States and Brazil are under review as a result of the raw material constraints, with partial curtailments to its production schedule beginning in May 2026. The company operates major phosphate mining and processing facilities in Florida, including sites at Riverview, Bartow, and New Wales, as well as the Faustina facility in Louisiana. Management noted that production rates at those facilities were at target in the first quarter before the supply disruption emerged.
Capital expenditures for full-year 2026 have been revised down to $1.25 billion, reflecting a deferral of less time-sensitive spending in response to market conditions. In potash operations, Mosaic said unit costs would improve as the K3 mine shaft at its Esterhazy, Saskatchewan facility ramps up production and eliminates the historical flooding issues that had constrained output from that mine.
Mosaic is one of the largest producers of phosphate and potash crop nutrients in the world, with operations across North America, South America, and international markets. Phosphate and potash are classified as mined minerals with significant commodity market pricing exposure, making Mosaic's results a barometer of broader agricultural input market conditions.
