Mosaic's Phosphate Pivot: Cutting Production to Survive a Sulfur Storm
The Mosaic Company’s second-quarter 2026 earnings call was a study in disciplined crisis management. Facing an unprecedented sulfur supply dislocation—the Strait of Hormuz closure and a Kazakhstan blockade—management chose to curtail phosphate production rather than chase unaffordable raw materials. “We further curtailed phosphate production and minimized our purchases of high-cost raw materials,” said CEO Bruce Bodine. “We've locked in a significant portion of our third quarter sulfur supply at reasonable prices that, while historically elevated, are still well below the current spot market.” (component_hash=987891173355069264) That decision, repeated across the portfolio, is the central narrative of this report: a large-cap fertilizer producer actively shrinking supply to preserve cash, while positioning for a sharp rebound in demand.
A Supply Squeeze with Global Consequences
The sulfur shock is not merely a cost problem; it threatens global food security. Bodine was blunt: “We believe global phosphate production will fall well short of last year by up to 30 million tonnes.”
The math is straightforward—without sufficient sulfur, phosphate plants cannot run. Mosaic’s own operating rates reflect the constraint: Louisiana is 100% down, Bartow at 40%, and other Florida plants in the mid-70s. CFO Luciano Pires quantified the cost impact: “In quarter 2, our raw materials costs averaged $522 per long ton for sulfur and $621 per tonne for ammonia… For quarter 3, we settled a sulfur contract at $705 per ton.” (component_hash=7355054310678983477) These are historically elevated levels, yet Mosaic’s realized stripping margin remains “well above historical averages”—a testament to its advantaged Gulf Coast sulfur relationships.Another season of under application will only exacerbate the problem… crop yields will suffer, which could lead to food security challenges around the world in the near term.
Farmers, Yields, and the Coming Recovery
The demand side is equally dire. Jenny Wang, EVP Commercial, outlined a brutal arithmetic: “North America phosphate application was down close to 15% versus the normal year. And this year, we are forecasting this application rate to further cut by around 20%… we're talking about over 30% phosphate down this year in '27.” (component_hash=7317554086845246398) That under-application is already showing up in yields, especially in Brazil, where “despite increased harvest areas, the yield actually came down.” Yield impact is the company’s central thesis for a demand recovery: as crops deplete soil phosphorus, farmers will have no choice but to replenish—especially once crop prices rise. Bodine: “We're seeing early signs of this in Brazil… over the past several weeks, fertilizer shipments to Brazil have been very strong.” (component_hash=987891173355069264) The company is confident that a bounce in ag commodity prices will restore farmer incomes and, with it, fertilizer affordability.
The prior quarter’s call set the stage for this pivot. Management had already flagged the working capital release and curtailments, but the tone then was more cautionary. In May 2026, Bruce said: “We have been saying that $300 million to $500 million release of working capital… we do see release of more working capital in second quarter and throughout the year.” (component_hash=2841859040017889167) Now that release is more obvious—cash flow from operations improved in H1, and Pires expects “sequential improvements in free cash flow in the third and in the fourth quarters.” (component_hash=7355054310678983477) These are not idle promises; the fundamentals confirm the strain. Mosaic’s gross margin has collapsed from 19% in Q2 2025 to 7.9% in Q2 2026, while operating income flipped to a loss of $373 million. Yet the company is deliberately avoiding capital-intensive inventory builds, slashing SG&A 20% YoY, and reallocating capital to Mosaic Biosciences business—a high-margin growth engine that is “on track to double its revenues once again this year.”
Strategy: Manage What You Can, Invest Where It Matters
The longer-term story is not just survival. Mosaic is using the downturn to reshape its portfolio: divesting non-core assets (Carlsbad sale, Araxa process), terming out short-term debt with a $1 billion term loan, and maintaining a full $2.5 billion revolver. Pires emphasized the balance-sheet discipline: “We have not tapped our revolver at all.” (component_hash=7355054310678983477) At the same time, the company is investing in potash capacity (HydroFloat at Esterhazy) and Biosciences, which offers a differentiated growth vector independent of sulfur prices.
The market has barely reacted—the stock is flat over the past 90 days—but the call lays out a clear path: short-term pain, longer-term gain. As Bodine concluded, “Mosaic remains in an advantageous position with access to U.S. sulfur and open shipping channels in the Americas… we're strong and resilient and better markets are ahead.” (component_hash=4512100160452122522) With the global phosphate application deficit already reaching destructive levels, the eventual recovery could be sharp. The question is how long this bridge needs to be.
