What were the primary reasons for Mosaic's Q1 net loss of $258 million, compared to a $238 million profit in the prior-year period?

The primary reasons for Mosaic's Q1 net loss were: (1) $442 million in charges related to the idling of its Araxá and Patos de Minas phosphate mines in Brazil; (2) $323 million in pre-tax special items; and (3) sharply rising input costs for ammonia and sulfur—key raw materials for phosphate and phosphoric acid production—driven by geopolitical tensions in the Middle East, increased shipping costs due to vessel rerouting, and natural gas price volatility affecting ammonia manufacturing costs.

How did Mosaic's potassium fertilizer business perform in Q1, and what does this indicate about global potash market conditions?

Mosaic's potassium fertilizer (potash) business delivered a 12.7% increase in operating profit in Q1, and the company stated that the global potash market 'remains balanced'—indicating stable supply-demand dynamics, resilient pricing, and continued operational strength in this segment despite significant headwinds in its phosphate operations.
