Mosaic Plunges Pre-Market After Q4 Earnings Miss and JPMorgan Downgrade
The Mosaic Company (NYSE: MOS) is seeing its shares plunge by over 7% in pre-market trading this Thursday, extending losses from yesterday's session. The sharp decline follows the fertilizer giant's disappointing fourth-quarter 2025 earnings report, which missed analyst expectations, and a subsequent downgrade by JPMorgan Chase & Co..
Shares of The Mosaic Company, a key player in the fertilizers and agricultural chemicals industry, are down 7.20% ahead of the market open, significantly underperforming the broader S&P 500. This pre-market sell-off builds on a 5.30% drop experienced on Wednesday, February 25, 2026, when the stock closed at $26.98. The catalyst for this pronounced move is a combination of weaker-than-expected financial results and a bearish analyst call.
Q4 Earnings Fall Short Amidst Headwinds
Mosaic reported a GAAP loss of $1.64 per share for the fourth quarter of 2025, with adjusted earnings coming in at $0.22 per share. This figure dramatically missed the Zacks Consensus Estimate of $0.48 per share, representing an earnings surprise of -53.98%. Revenue for the quarter also fell short, reaching $2.97 billion against an anticipated $3.02 billion.
The company attributed the weak performance primarily to lower phosphate demand in the United States and softer sales volumes. Compounding these demand-side issues are rising input costs, particularly a sharp increase in sulfur prices. Mosaic has already extended temporary curtailments of single super phosphate (SSP) production at its Brazilian facilities due to these elevated sulfur costs. JPMorgan estimates Mosaic's average sulfur costs could rise by approximately $525 million in 2026 year-over-year.
JPMorgan Downgrade Adds Pressure
Further exacerbating the negative sentiment, JPMorgan Chase & Co. downgraded Mosaic's stock rating today from "Neutral" to "Underweight," setting a new price target of $24.00. The firm cited expectations for lower earnings in 2026 as a base case, projecting a decline in EBITDA for Mosaic's Fertilizantes operation due to lower phosphate prices and increased sulfur costs. This downgrade underscores concerns about the company's profitability in the near term as inflationary pressures work their way through the income statement.
Despite management's outlook for operational improvements and growth in 2026, focusing on phosphate and potash production and cost control, the immediate market reaction highlights investor apprehension regarding current market dynamics and the impact of rising input costs on the company's bottom line. The stock's recent performance has been soft, with an 8.4% decline over the past week and a 4.8% decline over the past month, indicating a broader period of pressure.
