Mosaic Company (The) (MOS) Stock Price & How to Invest

The Mosaic Company is a leading global producer and marketer of concentrated phosphate and potash, the two primary crop nutrients it mines, processes, and distributes to farmers and dealers worldwide. Its business runs across three reporting segments: Phosphates (finished phosphate fertilizers plus premium products like MicroEssentials), Potash (potassium fertilizer from mines in Saskatchewan, New Mexico, and elsewhere), and Mosaic Fertilizantes, a large Brazil-based production and distribution arm that now drives roughly a third of the company's business. Mosaic sells into agriculture, where nutrient demand is tied to planted acreage, crop prices, and farmer economics.

As a commodity producer, Mosaic's profitability is highly cyclical: revenue and margins expand when potash and phosphate prices are high and compress when nutrient prices fall or raw-material costs (sulfur, ammonia, natural gas) spike. In early 2026 the company posted strong phosphate volumes but a net loss, as surging sulfur and ammonia costs crushed phosphate margins and prompted temporary production curtailments. The investment picture is therefore about global fertilizer supply and demand, the spread between nutrient prices and input costs, and management's ability to run its potash and Brazil operations efficiently through the cycle.

Mosaic is a cyclical commodity producer, so its earnings can swing dramatically with potash and phosphate prices and are exposed to sharp input-cost inflation in sulfur, ammonia, and natural gas. In early 2026 rising input costs pushed the company to a quarterly net loss and forced temporary curtailments at U.S. phosphate plants and idled some Brazilian SSP output, and it withdrew full-year phosphate production guidance. Global competition is intense, with OCP Group in phosphates and Belarusian and Russian producers in potash affecting prices and supply. Weather, weak farm economics, trade policy, currency moves (especially the Brazilian real), and regulatory or environmental costs at mining and processing sites add further volatility.

We give no verdict on Mosaic Company (The). Both cases are real, which is why the question is contested at all, so here is the strongest version of each.

The case for buying. Global crop-nutrient demand. Mosaic's core driver is worldwide demand for phosphate and potash, which is linked to planted acreage, crop prices, and farmer affordability. The most optimistic published target, $35.00, assumes this works close to its best case.

The case against. Mosaic is a cyclical commodity producer, so its earnings can swing dramatically with potash and phosphate prices and are exposed to sharp input-cost inflation in sulfur, ammonia, and natural gas. The most pessimistic target, $19.00, is roughly what MOS is worth if this bites instead.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Mosaic Company (The)'s investor relations page or your broker.

• Revenue (TTM): ~$12.4 billion
• Market cap: ~$6.8 billion
• Q1 2026 net result: ~$258 million net loss
• Diluted EPS (TTM): ~$0.14
• Dividend (annualized): ~$0.88 per share (~4% yield)
• Analyst 12-month target (avg): ~$27

Mosaic's trailing revenue of roughly $12.4 billion contrasts with thin trailing profitability, reflecting the input-cost squeeze that produced a first-quarter 2026 net loss. The very high trailing price-to-earnings ratio is a function of depressed earnings rather than a growth premium, which is typical for a commodity producer near a cyclical low. Figures are approximate and move with nutrient prices and quarterly results.

These are the investment theses MOS naturally fits into. Each links to a full theme guide listing every other stock that belongs and the ETFs commonly used as a passive proxy.

Other names that sit close to MOS: same theme, named as a direct competitor, or held beside it in the same funds. Each entry says which. Worth a look if you are thinking about diversification within a thesis rather than concentration on one ticker.

There are three common ways to get MOS exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic portfolio, so MOS sits alongside other stocks that express the same thesis.

Walnut takes the portfolio route. Describe a thesis where MOS fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.
