Mosaic rises 17.4% after third-quarter loss prompts analyst scrutiny

What happened

Mosaic (MOS) rose 17.4% on November 4, 2026, because of its third-quarter results, which included a per-share loss and triggered analyst questions on the outlook. The company reported a loss of $0.19 per share against a Zacks consensus loss of $0.03 in its November 3 press release. The Nov. 4 earnings call featured commentary and analyst questions about cost pressures, sales volumes and the outlook. Media and analysts noted the results missed expectations, citing higher raw material costs and shrinking margins, according to Zacks Investment Research and Seeking Alpha.

How big was the move

The stock closed at $21.62 after opening 3.1% above the previous close and traded at 2.1 times its 20-day average volume. The session's move was 5.2 times a typical daily move for the stock and was 14.2 percentage points better than the Basic Materials sector median, which rose 3.2% on the day. The S&P 500 rose 1.6% on the day; over the last five sessions the stock rose 17.9% as the S&P 500 fell 0.7%. These figures indicate the reaction was concentrated in Mosaic rather than driven by a broad market swing.

The technical picture

Technically the stock showed short-term strength but weak longer-term trends. The stock was 16.1% above its 20-day moving average but 0.8% below its 50-day moving average and 9.1% below its 200-day moving average. The 50-day average is below the 200-day average, a sign of a weak longer-term trend. The Relative Strength Index (14 days) stood at 62, in the neutral range between 30 and 70. The stock remained 33.0% below its 52-week high. Over one month the stock rose 3.2%, but it fell 7.8% over three months and fell 20.7% over one year, leaving it 32.9 percentage points behind the S&P 500 over the past year. Short-term volatility was elevated: 53% annualized over 60 days, higher than 85% of its own readings over five years.

Fundamentals and valuation

For the four quarters through September 30, 2026, Mosaic reported revenue of $11.53 billion, a decline of 3.1% from a year earlier, and diluted earnings per share of $-1.33, which fell 134.5% from a year earlier. Gross margin narrowed to 7.8% from 15.6% a year earlier, and operating margin dropped to 2.3% from 8.6% a year earlier. Free-cash-flow margin was 7.0% and return on invested capital was 0.2%, underscoring weak profitability. The balance sheet showed net debt of 4.2 times EBITDA and share count over one year decreased by 0.5%.

Valuation metrics reflected a stretched price relative to near-term earnings expectations. The stock traded at 61.0 times expected price to forward earnings, while free-cash-flow yield was 13.8%. PromtFinance scores were weak across most measures. Value scored 43 (Weak) and Stability scored 34 (Weak). Growth scored 3 (Very weak), Quality 11 (Very weak), Momentum 28 (Very weak) and Revisions 3 (Very weak). Those scores, together with compressed margins and elevated leverage, suggest investors are pricing in a recovery that has not shown up in recent results.

Earnings and analyst expectations

Mosaic’s last report on November 3, 2026, showed earnings per share of $-0.19 against $-0.01 expected, 1656.0% below estimates. The company had zero consecutive quarters beating estimates and an average surprise over the last four reports of 100.0% below estimates. Typical two-day reaction after recent reports was a fall of 0.6%, so the market’s sizable one-day rally on November 4 represented an atypical, positive reassessment. Analysts' consensus price target was $24.90, 15.2% above the closing price. Forty-nine analysts covered the stock and 29% rated the stock Buy or Strong Buy, with the consensus rating at Hold.

The Nov. 4 earnings call focused on cost pressures and sales volumes, issues central to whether Mosaic can restore margins. With net debt of 4.2 times EBITDA and operating margins well below year-earlier levels, market expectations will hinge on evidence of margin improvement or meaningful debt reduction.
