Mosaic reported a third-quarter 2026 net loss of $72 million, or $0.23 per diluted share, compared with net income of $411 million, or $1.29 per share, a year earlier. Net sales fell to $3.1 billion from $3.5 billion, and adjusted EBITDA dropped to $324 million from $806 million, mainly on lower sales volumes and higher raw material costs in phosphate and Mosaic Fertilizantes. For shareholders, the results show a much weaker quarter, with the company citing expected improvement in fourth-quarter free cash flow.

The company withdrew its 2026 phosphate production guidance as it reviews raw material constraints, and it cut 2026 capital expenditure guidance to $1.25 billion, which matters to shareholders because the earnings decline and guidance changes reduce visibility on the year.

Pre-tax book impact of $350 to $400 million expected in Q1 2026, with $275 to $300 million for asset impairment and write-offs
