The Mosaic Company continues to reinforce its standing as one of the biggest companies in Tampa Bay, posting strong third-quarter 2025 results while advancing long-term investments across fertilizer, biosciences and clean energy initiatives.
Headquartered in Tampa, Mosaic is one of the region’s most prominent publicly traded companies and a key player in global agriculture markets.
The company reported net income of $411 million in the third quarter, with adjusted EBITDA of $806 million, reflecting improved operating performance across its phosphate, potash and Brazil-based businesses.
Net sales totaled $3.5 billion for the quarter, up from $2.8 billion a year earlier, as higher prices and improving production volumes offset market and operational pressures.
A Tampa-based company with global reach
Mosaic’s Tampa headquarters anchors a business with operations spanning North America, South America and key global export markets.
While often associated locally with its Plant City operations and phosphate production footprint, Mosaic’s reach extends well beyond Florida.
The company produces and markets phosphate and potash fertilizers used by growers worldwide and has increasingly expanded into biological and specialty products through Mosaic Biosciences.

Those efforts are aimed at improving nutrient efficiency and crop performance while reducing environmental impact.
Mosaic Biosciences product sales more than doubled during the first nine months of 2025, and the company expects full-year sales to reach approximately $70 million.
The segment is projected to contribute positively to earnings in the fourth quarter.
Phosphate recovery drives momentum
One of the most closely watched developments for Mosaic in recent years has been the recovery of its phosphate operations.
Third-quarter phosphate production volumes reached 1.7 million tonnes, marking the third consecutive quarter of improvement.
Production climbed to approximately 1.8 million tonnes for the three-month period ending in October, following the resolution of operational issues at facilities in Bartow and Riverview.

Phosphate operating earnings improved to $102 million, up from $8 million a year earlier. Mosaic said it is now focused on sustaining higher operating rates and lowering conversion costs as production stabilizes.
The company expects phosphate sales volumes of 1.7-1.9 million tonnes in the fourth quarter, with pricing supported by tight global supply and reduced exports from China.
Potash and Brazil operations strengthen earnings mix
Mosaic’s potash business continues to benefit from strong global demand and higher prices.
Potash operating earnings totaled $229 million in the third quarter, more than double the prior year, while adjusted EBITDA reached $329 million. Production efficiencies helped lower cash costs even as higher-cost mines remained in operation.
In Brazil, Mosaic Fertilizantes delivered one of the strongest performances across the company.

Operating earnings rose 71% year over year to $96 million, while adjusted EBITDA increased 190% to $241 million.
Although fertilizer shipments in Brazil were tempered by tighter credit conditions, Mosaic said it recovered $27 million in previously written-off bad debt during the quarter and recorded no material new bad-debt expense.
Capital discipline and asset strategy
Mosaic continues to actively manage its asset base as part of a broader capital discipline strategy.
After the quarter closed, the company completed the sale of the Patos de Minas mine for $111 million and the Taquari potash mine for $27 million.

The transactions generated immediate cash proceeds and reduced future capital and environmental obligations.
Mosaic is also evaluating strategic alternatives for its Carlsbad, New Mexico potash mine and studying potential niobium opportunities tied to its Brazil phosphate operations.
Shareholder returns remain intact
As earnings rebounded, Mosaic maintained its dividend policy.
The company paid a $0.22-per-share dividend in the third quarter, and in December its board approved another quarterly dividend at the same level.

The dividend will be paid March 19, 2026, to shareholders of record as of March 9, 2026.
Mosaic said future dividends remain subject to board approval, but improving cash flow and operating performance continue to support shareholder returns.
A fixture among Tampa Bay’s largest companies
As one of the largest public companies headquartered in Tampa, Mosaic plays an outsized role in the region’s economy, employment base and global business profile.
From fertilizer and biosciences to emerging energy and sustainability initiatives, the company’s scale and diversification place it firmly among the biggest companies in Tampa Bay and among the most closely watched public companies in Florida.
With production stabilizing, markets tightening and capital investments sharpening, Mosaic enters 2026 positioned to remain a cornerstone of Tampa’s corporate landscape.
