Third Quarter Loss Followed by a Rebound After Results

Mosaic reported its third quarter 2026 figures on November 3, 2026, after the market closed. Net sales came in at USD 3.1 billion against about USD 3.08 billion expected, but an operating loss of USD 97 million and a net loss of USD 72 million, or USD 0.23 per diluted share, weighed on the quarter. Adjusted EBITDA reached USD 324 million, while the adjusted loss of USD 0.19 per share fell USD 0.20 short of consensus. Published coverage reported that Mosaic (NYSE:MOS) rose 9.83% in after-hours trading on November 4, 2026, to USD 20.23 from an USD 18.42 close. Potash volumes were 2.1 million tonnes.

Trough Guidance, Sulfur Contracts and Cost Targets Drive the Rebound Case

No catalyst beyond the results was identified, and the reaction shows that a stock can rise on a quarter that missed expectations. Management said the fourth quarter should mark the EBITDA low, most visibly in phosphate. Sulfur for the fourth quarter was contracted at USD 615 per long ton, while realized sulfur cost is expected at USD 800 to USD 850 per tonne and ammonia at USD 590 to USD 610. Conversion costs fell about USD 11 per tonne sequentially, and 2026 selling and administrative costs are guided to USD 510 million to USD 530 million, below USD 500 million in 2027.

Valuation, Price Range and Phosphate Risks After a Weekly Surge

Mosaic has a Market Value of about USD 6.42 billion, inside the USD 2 billion to USD 10 billion Mid cap band. The USD 22.15 price sits about 31% below the 52-week high and 30% above the low, calculated from the published range. A Dividend Yield of 4.78% was cited, analyst targets span USD 17 to USD 35, and one Fair Value estimate of USD 21.24 sits just below the current price. Key risks include phosphate losses, sulfur and ammonia input costs, volatile crop prices and a fourth quarter trough that could still produce weak results. A gain of this size can reverse quickly.

Where Things Stand

Mosaic (NYSE:MOS) rose because investors focused on management's trough language, lower 2026 capital spending and the refinancing of long-term maturities through 2028, not on a profit beat. The 21.01% weekly gain lifted the USD 22.15 price, which still sits below the USD 32.25 52-week high and is down 4.83% over three months. Fourth quarter phosphate margins, the USD 615 per long ton sulfur contract and the 2027 cost targets are the checkpoints to watch. A move like this may not last, and this is not advice.
