Mosaic and CF Industries both sell essential crop nutrients, but their current economics are moving in different directions. Mosaic is exposed mainly to phosphate and potash. CF produces nitrogen, where energy costs, global capacity and regional supply disruptions set a different profit cycle.
Mosaic's second-quarter update showed 1.4 million tonnes of phosphate sales and 2.0 million tonnes of potash sales. Management reduced phosphate production, cut costs and lowered capital spending as high sulfur costs pressured the business. Sulfur is a key phosphate input, so a higher selling price does not automatically produce a wider margin.
CF's second-quarter results were stronger. The company reported $1.34 billion of first-half net earnings and $2.18 billion of adjusted EBITDA. Management said elevated natural gas prices could pressure marginal European nitrogen production and support the global clearing price. CF still faced maintenance costs and lower ammonia volumes, but the market structure was more favorable.
Why the cheaper stock can be riskier
The source comparison placed Mosaic at roughly 0.5 times trailing sales and CF at 2.3 times. That gap looks large, yet sales multiples ignore the cost of producing those sales. The same source calculated a 2.7% trailing operating margin for Mosaic versus 39% for CF, with materially higher debt relative to Mosaic's market value.
Those figures are not perfectly comparable across product mixes, but they explain why investors should not treat low price-to-sales as automatic value. Mosaic needs phosphate volumes, sulfur costs and cash generation to improve. CF must preserve nitrogen pricing while controlling gas and maintenance costs.
Two different watch lists
For Mosaic, the next report should show whether phosphate sales reach the upper end of guidance and whether negotiated sulfur costs stay below volatile spot prices. Potash stability would provide a counterweight.
For CF, investors should track realized nitrogen prices, production availability and capital returns. CF currently has the cleaner operating momentum, while Mosaic offers more recovery upside if phosphate economics normalize. The choice is less about fertilizer demand than which part of the fertilizer chain captures the margin.
