The Mosaic Company (MOS) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Mosaic published the results on November 3, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Mosaic reports EPS two ways: GAAP, under the accounting rules every US filer follows, and adjusted, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• Segment net sales include intersegment sales. Corporate, Eliminations and Other removes them and also carries Mosaic's China and India distribution businesses, so the four rows sum to consolidated net sales.
• Mosaic committed in March 2026 to divest the Araxá mining and chemical complex in Brazil and idle related mining at Patrocínio; its 10-Q puts the added expense for the first nine months of 2026 at about $496 million.

How Mosaic splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• Mosaic's Phosphate revenue was $1.3 billion in Q3 2026, flat on $1.3 billion in Q3 2025, 42% of total revenue.
• Mosaic's Mosaic Fertilizantes revenue was $1.3 billion in Q3 2026, down 21% from $1.6 billion in Q3 2025, 40% of total revenue.
• Mosaic's Potash revenue was $643 million in Q3 2026, down 7% from $695 million in Q3 2025, 21% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

In its Q3 2026 release, Mosaic said:

“As a result, full-year potash production is now expected to be 8.6 million tonnes in 2026.”

“Fourth quarter 2026 sales volumes are expected to be in the range of 2.3 to 2.6 million tonnes, with realized mine gate MOP prices in the range of $255 to $275 per tonne.”

“DAP prices at the plant are expected to average $820 to $840 per tonne.”

“Fourth-quarter stripping margins and adjusted EBITDA are expected to decline further as higher-cost raw materials purchased and consumed during the third quarter flow through cost of goods sold, reflecting the two- to three-month inventory cycle.”

• Q3 2026 (this page), reported Nov 3, 2026

Mosaic reported Q3 2026 net sales of $3,100.6 million, against $3,452.1 million a year earlier. Before intersegment eliminations, Phosphate brought in $1,294.9 million, Mosaic Fertilizantes in Brazil $1,254.0 million and Potash $643.4 million. (Mosaic Form 10-Q, Q3 2026, Nov 4, 2026)

Mosaic mines phosphate rock in Florida, Brazil and Peru and processes it at facilities in Florida, Louisiana and Brazil, and it mines potash in Saskatchewan and New Mexico. It describes itself as the second largest integrated phosphate producer in the world and the leading fertilizer production and distribution company in Brazil. (Mosaic Form 10-K, 2025, Feb 27, 2026)

Mosaic said results primarily reflected lower sales volumes across all segments and higher raw material costs in Phosphate and Mosaic Fertilizantes, partly offset by higher phosphate prices. Phosphate volumes fell to 1.4 million tonnes from 1.6 million because Mosaic curtailed production for lack of affordable sulfur, while its DAP selling price rose to $838 a tonne from $714. Sulfur averaged $715 per long ton in the quarter. (Mosaic Q3 2026 release, Nov 3, 2026)

Mosaic Fertilizantes volumes dropped to 1.9 million tonnes from 2.8 million, which Mosaic put down mainly to curtailed domestic production and limited customer credit availability. Potash sold 2.1 million tonnes, against 2.3 million, at an MOP price of $276 a tonne; abnormal geological conditions at Esterhazy lowered ore grades. (Mosaic Q3 2026 release, Nov 3, 2026)

By customer location, Brazil accounted for $1,190.4 million of Mosaic's Q3 2026 net sales, the United States $902.3 million and Canada $401.1 million. Sales to Canpotex were $351.1 million. (Mosaic Form 10-Q, Q3 2026, Nov 4, 2026)

Mosaic posted a diluted loss of $0.23 a share in Q3 2026, against earnings of $1.29 a year earlier. Excluding notable items, its adjusted loss was $0.19 a share. Pre-tax notable items of $53 million included environmental reserve adjustments, facility closure expenses and restructuring costs, partly offset by a gain on Mosaic's investment in Ma'aden and currency gains. (Mosaic Q3 2026 release, Nov 3, 2026)

The Phosphate segment lost $194 million at the operating line, including $84 million of notable items, and its gross margin was negative $105 a tonne. Idle, turnaround and unabsorbed fixed costs were $77 million in Phosphate and $70 million in Mosaic Fertilizantes. Potash stayed profitable, with operating earnings of $189 million. (Mosaic Q3 2026 release, Nov 3, 2026)

Mosaic's 10-Q records an unrealized mark-to-market gain of about $38.0 million on its Ma'aden shares and a foreign currency transaction gain of $38.3 million in the quarter. The effective tax rate was 36.7% on a pre-tax loss, and diluted shares were 317.9 million against 319.4 million. (Mosaic Form 10-Q, Q3 2026, Nov 4, 2026; Mosaic Q3 2026 release, Nov 3, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Mosaic gives a numeric outlook in its release. For the fourth quarter of 2026 it expects Potash sales of 2.3 to 2.6 million tonnes at mine gate MOP prices of $255 to $275 a tonne, and Phosphate sales of 1.3 to 1.6 million tonnes with DAP at $820 to $840 a tonne. It now expects full-year potash production of 8.6 million tonnes. (Mosaic Q3 2026 release, Nov 3, 2026)

Mosaic expects fourth-quarter Phosphate stripping margins and adjusted EBITDA to decline further as costly third-quarter raw materials flow through cost of goods sold, with the benefit of its $615 per long ton fourth-quarter sulfur contract arriving mainly in the first quarter of 2027. It expects Mosaic Fertilizantes adjusted EBITDA to fall below third-quarter levels and is targeting 2027 capital spending below $1 billion. (Mosaic Q3 2026 release, Nov 3, 2026)

A consensus figure is the average of the models published by the analysts who cover Mosaic, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Mosaic's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning MOS is on is MOS a buy or a sell?, what analysts expect next is on the MOS forecast, and what the company does is on the The Mosaic Company (MOS) stock page.

Every number on this page can be traced to a document Mosaic published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
