The Mosaic Company

Industry Position

Fertilizer is priced at two nodes. Potash clears at the MOP price free on board the mine gate, set by negotiations among a small group of producers and by the timing of annual contracts with India and China. Phosphate clears at DAP free on board Tampa, which moves with sulphur and ammonia costs, Chinese export availability and Brazilian demand. Neither benchmark is traded on a futures exchange in the way copper or oil is, so contract settlement timing matters as much as the underlying balance.

Supply is concentrated on both sides. In potash, Nutrien, Mosaic, K+S, ICL and the Russian and Belarusian producers account for most of global capacity, with Canada and Russia holding the largest reserves. In phosphate, OCP in Morocco controls the largest rock reserves, China's export policy swings the seaborne market, and Mosaic is the largest North American integrated producer with a 72% share of the domestic finished phosphate market.

Demand follows agronomy rather than the industrial cycle. Global nutrient consumption grows with population and with the intensity of farming in Brazil, India and Southeast Asia, and it contracts when crop prices fall far enough to make fertilizer unaffordable at the farm gate. That gives the market a floor over time but very little visibility within a season, which is why producers hold inventory and why contract negotiations can stall for months.

Competitive Advantages

Mosaic's potash position is a genuine cost advantage. Esterhazy K3, the largest underground potash mine in the world at 6.3 Mt of capacity, is highly automated and benefits from the 400,000 tonne Hydrofloat project, and the resulting cash cost of USD 75 per tonne sits in the first quartile. Belle Plaine's solution mining gives flexibility on product grade, including industrial MOP, and Colonsay can be dialled up or down to match demand.

In phosphate, integration from rock to finished granule is the moat. The Central Florida mines produced 9.5 Mt of rock in 2025, 47% of North American output, and that rock feeds four concentrates plants with 4.5 Mt of P2O5 capacity, so Mosaic captures the upgrading margin between raw rock and DAP rather than selling rock to a competitor's plant. Competitors such as CF Industries buy ammonia and sell nitrogen; Mosaic owns the scarce input, which is phosphate rock.

Product mix adds a premium layer. MicroEssentials, K-Mag, Aspire, PowerCoat and the Mosaic Biosciences portfolio sell at prices above commodity DAP and MOP because they bundle nutrient efficiency or micronutrients, and they are harder to substitute than a standard granule. The Brazilian distribution network, built through Mosaic Fertilizantes, gives direct access to farmers in one of the fastest-growing nutrient markets and captures retail margin that a pure producer forgoes.

Reserve life underpins all of it: 1,150 Mt of potash ore at 24.5% K2O over 48 years and 540 Mt of rock at 28.2% P2O5 over 28 years. Few competitors match that combination of grade and remaining life in both nutrients, and it means Mosaic can invest in productivity rather than in replacement tonnes.

Strategic Expansion

Growth is incremental and capital-disciplined. The Hydrofloat project at Esterhazy added 400,000 tonnes of capacity through improved recovery from existing ore, which is the cheapest form of potash growth available, and FY2026 potash guidance of approximately 9.0 million tonnes (range 8.9-9.1 million tonnes) reflects that ramp offsetting the Carlsbad sale.

Phosphate guidance calls for production at or above 7.0 million tonnes in FY2026, with the constraint being ore quality and chemical plant reliability rather than market access. Capital expenditure was guided down to USD 1.20 billion in August 2026 from USD 1.28 billion in FY2025, with the reduction concentrated in growth projects and sustaining spend held at USD 0.85 billion.

Brazil remains the strategic growth market. Mosaic Fertilizantes combines local phosphate mines, chemical complexes and blending capacity with a distribution business that reaches farmers directly, and it gives the company a position in a market where nutrient demand is growing faster than in North America. The 75%-owned Miski Mayo operation in Peru supports both the Brazilian and Asian rock requirements.

Mosaic Biosciences is the smallest but most optional investment. Biological products are sold alongside conventional fertilizer and require little capital, so they raise revenue per acre without adding mining capacity, and they give the sales force a reason to engage growers beyond price.

Risks & Outlook

Price exposure is unhedged by design. A USD 10 per tonne move in MOP changes annual EBITDA by about USD 83 million and a similar move in DAP by USD 60 million, and because the company only hedges natural gas inputs and CAD and BRL currency exposure, the full effect of a fertilizer price decline reaches the income statement. Potash contract settlements with India and China are the single largest swing factor for the year.

Input cost risk is concentrated in phosphate. Sulphur and ammonia are bought at market prices, and when both rise together the margin between rock cost and DAP price compresses regardless of how efficiently the plants run. Florida permitting, water management and hurricane exposure add operating risk that a Saskatchewan potash mine does not carry.

Brazilian and Peruvian operations bring currency and political risk, and the Brazilian distribution business carries receivables from farmers that are sensitive to credit conditions and crop prices. At the corporate level, capital expenditure above net income in FY2025 left limited free cash flow, and a prolonged downturn would test the balance sheet even with liabilities of USD 12.25 billion against assets of USD 24.48 billion.

The next one to two years hinge on potash volumes holding near 9.0 million tonnes and phosphate volumes recovering above 7.0 million tonnes while prices stay above cash cost. If both hold, the first-quartile potash position and the 72% phosphate share should generate enough cash to cover a reduced capital programme and restore the earnings base that the FY2022 peak demonstrated was possible. The profile closes with a VerityRank Score of 78/100.
