Mosaic (MOS) said Friday that Q4 North American fertilizer demand declined "well beyond normal seasonal softness."

The company said its Q4 phosphate and potash sales volumes totaled 1.3 million and 2.2 million metric tons, respectively.

The Q4 market for phosphates was down 20% compared to a year earlier because of lower relative affordability as compared with potash, which was also negatively affected, the company said.

The company said it adjusted its Q4 phosphate production plan and product mix, and redirected sales to markets with stronger demand.

But the company added that the industry expects possible record levels of global phosphate and potash shipments in 2026.

Shares of the company were down 6.5% in recent premarket activity.
