The Mosaic Company

MOS

FAVORABLE

June 1, 2026

Research Conclusion

At $23.32/share, MOS trades at a 22-32% discount to base-case intrinsic value of $26-35. Constructive long for cycle-aware value investors with 24-36 month patience. K3 Esterhazy potash asset is world-class at trough pricing; Florida phosphate permits irreplaceable; Brazil distribution provides earnings resilience. Probability-weighted expected return +27-32% with positively-skewed upside (bull +114-157%, bear -18-40%, stress -50-70%). Position sizing 2-4% of portfolio; add toward $19-20 on commodity weakness if thesis intact.

Company Overview & Moat Assessment

World's largest integrated potash and phosphate fertilizer producer, headquartered Tampa, FL. Formed 2004 from Cargill crop nutrition + IMC Global merger. Operates Saskatchewan potash mines including world-class K3 Esterhazy solution mine ($55-65/t cash cost), Florida and Louisiana phosphate (only large-scale permitted US supply chain), and 35-facility Brazil distribution network (Mosaic Fertilizantes). Structurally cyclical: potash prices $180-200/t (2020 trough) to $730/t (Q3 2022 peak). Mid-cycle EBITDA ~$2.5-2.7B annually on $11-12B revenue; potash and phosphate each ~40%, Brazil ~20% at normalized prices.

▲ Bull Case

  • Potash recovery to $320-360/t mid-cycle: India 2026 contract settles >$300/t CFR, Belarus sanctions persist, Canpotex discipline tightens, demand recovers. K3 at full ramp captures $235-245/t gross margin × 7.5M tonnes = $1.6-1.8B segment contribution.
  • K3 cost revolution is mispriced: Market applies blended ~$80-100/t mental model when K3 (~80% volume) operates at $55-65/t. Disaggregated analysis lifts FY2027 EBITDA to $2.55-3.0B+, supports EV/EBITDA re-rating from 4.6x to 6.5-7.5x, implying $48-60/share.
  • Phosphate supported by China + Florida advantage: Chinese export restrictions extend through 2027; OCP ramp slower than schedule; Florida logistics advantage sustains DAP at $580-640/t. Phosphate EBITDA returns to $1.0-1.2B annual run-rate by FY2027.

▼ Bear Case

  • Belarus sanction relaxation enables Russian re-entry: EU/US diplomatic settlement allows Belaruskali to re-export 5-8M tonnes at $230-250/t. Potash drops to $240-260/t; MOS potash segment EBITDA halves to $500-600M, consolidated EBITDA to $1.0-1.4B, dividend at risk.
  • OCP structural phosphate compression: Morocco's OCP adds 3-4M tonnes P2O5 capacity ahead of schedule while Chinese restrictions lift. DAP migrates toward OCP's $280-320/t cost floor; MOS phosphate margin compresses from $80-100/t to $30-50/t. Long-run earnings down 30-40%.
  • Input cost stress persists: Persian Gulf disruption keeps sulfur and ammonia elevated through 2026-2027. Q1 2026 case: finished DAP at $668/t produced segment loss due to input costs. Structural risk to phosphate ROIC if sustained.
Primary Debate on Wall Street

Consensus (20 analysts) PT $26.98, Hold rating (~16% upside vs. our $32-36 base case). Consensus prices in permanent earning power reduction vs. 2022 peak (partially correct but may over-discount cycle), phosphate compression from OCP as dominant narrative (timing debate: 5 vs. 10 years), lack of near-term catalysts, and FY2022 peak-cycle buyback credibility damage. Non-consensus debate: Is K3 properly priced as low-cost asset or is market applying blended-cost economics? Is Fertilizantes growth/margin expansion underappreciated? Is structural potash supply deficit (no new large mines outside Russia/Canada/Belarus) underpriced on 5-year view?

Top Catalysts
  • H1 2026 India MOP Contract Settlement (May-July 2026): >$300/t CFR most important near-term catalyst, validates potash floor
  • Q2 2026 Earnings (Jul/Aug 2026): Phosphate EBITDA recovery from Q1 loss, guidance restoration, potash volume confirmation
  • Chinese Phosphate Export Quota Decisions: Each quarter of continued restrictions adds ~$50-100M to annual phosphate EBITDA
  • Sulfur/Ammonia Price Normalization: Persian Gulf stabilization unwinds Q1 2026 input cost spike
  • K3 Segment Cost Disclosure: Management decision to disclose K3-specific economics would crystallize K3 mispricing thesis
  • Brazil Mato Grosso 2026/27 Acreage: Strong soy/corn expansion drives Fertilizantes volume and margin support
Top Risks
  • Belarus/Russia sanction relaxation (15-20% 3-year probability, HIGH impact -$15-20/sh): Enables Belaruskali re-export 5-8M tonnes at $230-250/t, potash collapse
  • OCP structural phosphate expansion (40-50% 5-year probability, MODERATE-HIGH -$5-8/sh): Morocco adds 3-4M tonnes capacity ahead of schedule, DAP floor compression
  • Florida phosphogypsum stack incident (4-6% annual probability, CATASTROPHIC): Multi-year regulatory and operational disruption
  • Corn/soybean price downturn (25-30% probability, MODERATE -$3-6/sh): Brazil distribution provides partial offset, demand historically recovers
  • Sulfur/ammonia input spike (15% probability, MODERATE-HIGH near-term): Q1 2026 case study, typically 3-6 month event
  • Brazilian FX deterioration (50% volatility probability, MODERATE -$1-3/sh): Partial hedging available, natural Brazil demand offset
  • Canpotex regulatory challenge (<5% probability, HIGH if materializes): Long-standing structure with historical tolerance
