You’ve probably seen the headlines. As of mid-January 2026, the Mosaic Company stock price has been on a bit of a wild ride, recently hovering around the $26 to $28 range. Just this morning, January 16, it was sitting at $26.43, down significantly from its 52-week high of $38.23.
It’s easy to look at a chart and see a downward slope, but if you're only looking at the price action, you're missing the real story.
Investing in a company like Mosaic isn't like buying a tech stock where growth is the only metric. This is a commodity play. Basically, it’s a bet on the world’s ability to feed itself. When the price of potash or phosphate swings, Mosaic's valuation follows suit. Honestly, the fertilizer market is one of the most misunderstood sectors on Wall Street because it’s so heavily tied to things no CEO can control—like the weather in the Midwest or Chinese export quotas.
The Recent Slump and Why It Happened
Why the recent dip?
A preliminary market update released earlier today, January 16, 2026, revealed that North American phosphate shipments for the fourth quarter of 2025 were down by about 20% compared to the previous year. That’s a massive hit. The company blamed a "slump in fertilizer demand" that went well beyond the usual seasonal slowdown.
Part of the problem was just bad luck with the weather. An early winter in late 2025 basically slammed the door shut on the "application window"—the brief period when farmers can actually put fertilizer into the soil. If they can't get it in the ground, they don't buy it. Simple as that.
Then you have the Brazil factor.

Mosaic Fertilizantes, the company’s Brazilian unit, is usually a powerhouse. But lately, credit constraints for Brazilian farmers and a surge of cheap phosphate imports from China have squeezed margins. It’s a classic case of supply-side pressure meeting a cash-strapped customer base.
Potash vs. Phosphate: A Tale of Two Nutrients
To understand the Mosaic Company stock price, you have to separate its two main products. They don't always behave the same way.
- Phosphate: This is where the struggle is real right now. While China has restricted exports to protect its domestic supply, which usually keeps prices high, the "affordability index" for farmers has tanked. Phosphates are currently expensive relative to the prices farmers are getting for their crops.
- Potash: This side of the business is actually doing okay. Management recently pointed out that potash remains "extremely affordable" for growers. Potash sales volumes for Q4 2025 came in at roughly 2.2 million tonnes, which is a solid showing given the circumstances.
Interestingly, Mosaic recently moved to streamline its potash operations. They just sold off their Carlsbad, New Mexico potash mine for $30 million to International Minerals Carlsbad, LLC. The goal? To focus almost exclusively on their high-margin Saskatchewan production. It’s a "less is more" strategy that some analysts, including those at Morgan Stanley, have actually praised.
The 2026 Outlook: Is the Worst Over?
Despite a rough end to 2025, the mood for the rest of 2026 is surprisingly constructive.
"Mosaic generated strong earnings despite operational and market challenges... we are focused on driving further improvements," says CEO Bruce Bodine.
There’s a real argument that Mosaic is currently undervalued. If you look at the Price-to-Earnings (P/E) ratio, Mosaic is trading around 6.5x to 6.8x. Compare that to the broader chemical industry average, which is often in the double digits, and you start to see why value hunters are sniffing around.

A Discounted Cash Flow (DCF) analysis as of January 2026 suggests an intrinsic value of about $28.84 per share. With the stock trading closer to $26, it’s sitting at roughly a 12% discount.
But wait. There’s more than just math here.
Global fertilizer consumption hit record levels in 2024 and 2025, and the International Fertilizer Association (IFA) thinks that trend will continue through 2029. Farmers can only skip a season of fertilizing for so long before their soil starts to fail them. They have to replenish those nutrients. This "must-buy" nature of the product creates a floor for the company eventually.
Real-World Risks to Watch
You can't talk about the Mosaic Company stock price without acknowledging the "wildcards."
- Geopolitics: Russia and Belarus are massive potash producers. If sanctions on them ease, the market could get flooded, driving prices down. If the conflict escalates, the opposite happens.
- China's Export Policy: China is the world's largest phosphate exporter. They've announced export restrictions that will last through at least the first half of 2026. This is a huge tailwind for Mosaic because it removes a major competitor from the global stage.
- The U.S. Farm Bill: Changes in government subsidies or the $12 billion agricultural aid package could suddenly give U.S. farmers the cash they need to go on a buying spree.
What Investors Are Actually Doing
Right now, the market is divided.
On one hand, you have the "dividend hunters." Mosaic just declared a quarterly dividend of $0.22 per share, payable on March 19, 2026. It’s a consistent payout that appeals to people who want to get paid while they wait for the cycle to turn.

On the other hand, you have the momentum traders who are scared off by the 20% drop in North American shipments. They see the Mosaic Company stock price trading below its 200-day moving average (which is currently around $30.87) and they see a "falling knife."
Basically, it comes down to your timeframe. If you’re looking at next week, it’s anyone's guess. If you’re looking at the next two years, the fundamental need for food hasn't changed.
Practical Next Steps for Your Portfolio
If you're watching Mosaic, don't just stare at the daily ticker.
First, keep a close eye on the February 24, 2024 earnings release. That’s when we’ll get the full audited details on the Q4 slump. If the management's guidance for the spring planting season is even slightly better than expected, the stock could see a sharp "relief rally."
Second, watch the Phosphate Affordability Index. When this index moves back into positive territory, it’s a signal that farmers will stop "mining their soil" and start buying commercial fertilizer again.
Finally, check the "spread" between Mosaic and its peers like CF Industries or Nutrien. Lately, Mosaic has been underperforming the sector, which suggests the issues are company-specific (like the Brazil credit problems) rather than a total collapse of the agriculture industry. This often creates a "catch-up" opportunity for the laggard.
The current Mosaic Company stock price reflects a lot of pessimism, but in the commodity world, that's often when the best entries happen. Just remember that in this sector, patience isn't just a virtue—it's a requirement.
Actionable Insight: Monitor the USDA's reports on "Planting Intentions" for the 2026 season. If corn acreage is projected to rise, Mosaic’s demand will likely follow. Also, track the price of Muriate of Potash (MOP) in the Brazil spot market; it’s often a leading indicator for Mosaic's quarterly performance before the official numbers are released.
