Mosaic reported a sharp earnings swing as soaring sulfuric acid costs eroded margins. The fertilizer‑mining group said the war in the Middle East and fresh Chinese export curbs drove raw‑material prices to record highs, prompting it to pull its phosphate production outlook and trim capital spending for the year and reassess its operating plan through 2025.

The company warned that sulfuric acid, a key input for phosphate fertilizers and a staple for heavy industry, is tightening across its supply chain. With demand from food, metal, paper and semiconductor sectors climbing, Mosaic has already begun scaling back output at its Louisiana and Bartow plants while reviewing further cuts in Brazil by year‑end.

Mosaic said it is closely monitoring raw‑material markets and has taken “initial steps” to partially curtail production, signalling that higher input costs could force a broader reassessment of its growth strategy. Investors will watch how these adjustments affect the firm's cash flow, given that fertilizer margins have already been squeezed by volatile commodity pricing this.

By pulling its phosphate guidance and limiting capex, Mosaic aims to preserve liquidity amid an environment where sulfuric acid shortages could linger. The move underscores the vulnerability of fertilizer producers to geopolitical shocks and trade policy shifts, reinforcing the need for diversified sourcing strategies to sustain profitability over the next quarter as costs remain elevated.
