FOR IMMEDIATE RELEASE

THE MOSAIC COMPANY REPORTS FOURTH QUARTER AND

FULL YEAR FISCAL 2013 RESULTS

PLYMOUTH, MN July 16, 2013 – The Mosaic Company (NYSE: MOS) reported fourth quarter fiscal 2013 net earnings of $486 million, compared to $507 million a year ago. Earnings per diluted share were $1.14 in the quarter compared to $1.19 last year. Mosaic’s net sales in the fourth quarter of fiscal 2013 were $2.7 billion, down from $2.8 billion last year. Operating earnings during the quarter were $621 million, down from $671 million a year ago, as record potash and strong phosphate sales volumes were more than offset by lower realized prices.

“Our focus on planning and execution paid off, with Mosaic achieving record potash and strong phosphate shipments during the quarter,” said Jim Prokopanko, President and Chief Executive Officer of Mosaic. “Mosaic delivered outstanding results despite difficult external factors such as the late and compressed North American spring planting season, and additional logistical challenges. The long-term outlook for Mosaic remains compelling, and we are executing well to capture the opportunity.”

Cash flow provided by operating activities in the fourth quarter of fiscal 2013 was $855 million compared to $1.2 billion in the prior year. The year-over-year change was primarily driven by unusually strong cash flow in the prior year period as a result of favorable working capital trends. Capital expenditures totaled $348 million in the quarter. Mosaic’s total cash and cash equivalents were $3.7 billion and long-term debt was $1.0 billion as of May 31, 2013.

Full Year

For the year ended May 31, 2013, net income was $1.9 billion, or $4.42 per diluted share, compared to $4.42 per diluted share in fiscal 2012. Net sales were $10.0 billion, down from $11.1 billion a year ago. Full-year operating earnings were $2.2 billion, down from $2.6 billion a year ago. Lower net sales and operating earnings for the year were primarily driven by lower realized prices for both potash and phosphate, partially offset by higher potash volumes. Full year selling, general and administrative (SG&A) expenses were $427 million compared to $410 million last year. Net cash provided by operating activities was $1.9 billion.

Business Highlights – Fourth Quarter and Full Year Fiscal 2013

Potash

“We are beginning to see the benefits of the expansion projects that we started five years ago,” Prokopanko said. “We continue to forecast calendar 2013 will be a near record year for potash shipments, and that the world will need our new capacity. Our decision to defer the next phase of the expansions is primarily a reflection of the current construction cost environment though we will continue to monitor the global supply and demand outlook for potash. We expect the delay will result in higher returns for these projects.”

Net sales in the Potash segment totaled $1.0 billion for the fourth quarter, flat with last year, as record shipment volumes were offset by lower realized prices. The decline in realized prices was driven by both lower market prices for MOP, as well as a higher mix of international volumes, which are predominantly lower-priced standard grade potash. Gross margin was $489 million, or 47 percent of net sales, compared to $514 million, or 50 percent of net sales, a year ago. Gross margin excluding Canadian Resource Taxes and Royalties, a measure comparable to certain peer reporting, was 56 percent in the fourth quarter, compared to 59 percent a year ago. Operating earnings were $445 million, down four percent compared to $464 million in the prior year. The year-over-year decrease in operating earnings was driven by lower realized prices and higher labor and depreciation expenses as new projects were brought into production, partially offset by higher volumes.

The fourth quarter average MOP selling price, FOB plant, was $368 per tonne, down from $455 a year ago. The Potash segment’s total sales volumes for the fourth quarter were 2.6 million tonnes, compared to 2.0 million tonnes a year ago.

Potash production was 2.5 million tonnes, or 95 percent of operational capacity, up from 1.9 million tonnes, or 85 percent of operational capacity, a year ago. Operational capacity increased from 9.3 to 10.7 million tonnes, year-over-year, primarily due to the reversion of the tolling agreement.

Phosphates

“Our Phosphates business ended the year on a strong note, with robust shipments worldwide,” Prokopanko said. “Despite near-term softness, the phosphate market looks balanced over the medium term, with expected strong demand growth absorbing new supply. Longer term, we continue to project constructive fundamentals, which bodes well for our investment in the Saudi Arabian joint venture.”

Net sales in the Phosphates segment were $1.7 billion for the fourth quarter, down seven percent compared to last year, primarily driven by lower finished product prices. Gross margin was $290 million, or 17 percent of net sales, compared to $322 million, or 18 percent of net sales, for the same period a year ago. The year-over-year change reflects lower finished product prices, partially offset by lower raw material costs, specifically phosphate rock and sulfur. Phosphate rock costs were down from $71 to $64 per tonne, reflecting the benefit from full production at the South Fort Meade rock mine. Operating earnings were $198 million, down 12 percent, compared to $224 million last year.

The fourth quarter average DAP selling price, FOB plant, was $483 per tonne, compared to $494 a year ago. Phosphates segment total sales volumes were 2.9 million tonnes, roughly flat with last year.

Mosaic’s North American finished phosphate production was 2.1 million tonnes, or 85 percent of operational capacity, roughly flat with the same period a year ago.

Other

SG&A expenses were $122 million for the fourth quarter, compared with $117 million last year. Other operating expenses were $26 million for the fourth quarter, down from $46 million a year ago which included a $21 million adjustment to phosphate asset retirement obligations.

Financial Guidance

“With near record crop nutrient affordability, we anticipate continued strong demand for the remainder of calendar 2013, while generally cautious distributor behavior and a strengthening U.S. dollar will impact prices,” Prokopanko said. “We expect the current price weakness to moderate over time, as demand growth absorbs the additional supply of phosphate and potash. Over the longer term, Mosaic is well positioned to capitalize on the ever increasing demand for grain and oilseeds.”

The guidance below reflects the change from fiscal to calendar year end.

Total sales volumes for the Potash segment are expected to range from 1.8 to 2.1 million tonnes for the third calendar quarter of 2013, compared to 1.8 million tonnes last year. Mosaic’s realized MOP price, FOB plant, for the third calendar quarter of 2013 is estimated to range from $330 to $360 per tonne. Mosaic’s gross margin rate in the segment is expected to be in the mid to high 30 percent range during the third calendar quarter.

Total sales volumes for the Phosphates segment are expected to range from 2.9 to 3.3 million tonnes for the third calendar quarter of 2013, compared to 2.9 million tonnes last year. Mosaic’s realized DAP price, FOB plant, for the third calendar quarter of 2013 is estimated to range from $430 to $465 per tonne. Segment gross margin percentage in the third calendar quarter is estimated to be flat with the prior quarter.

The Potash segment operating rate is expected to decline during the second half of calendar 2013 due to planned seasonal maintenance turnarounds and a curtailment of production at Colonsay. The Company may also curtail production at other mines, if required to match production volumes to market demand for these products. The third calendar quarter operating rate is expected to be below 75%. The Company’s operating rate at its North American phosphate operations is expected to be in the mid-80 percent range of operational capacity during third calendar quarter of fiscal 2013, and includes scheduled turnarounds.

Selected Non-GAAP Financial Measures and Reconciliations

The Company has presented above gross margin excluding Canadian resource taxes and royalties (“CRT”) for Potash which is a non-GAAP financial measure. Generally, a non-GAAP financial measure is a supplemental numerical measure of a company’s performance, financial position or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with U.S. generally accepted accounting principles (“GAAP”). Gross margin excluding CRT is not a measure of financial performance under GAAP. Because not all companies use identical calculations, investors should consider that Mosaic’s calculation may not be comparable to other similarly titled measures presented by other companies.

Gross margin excluding CRT provides a measure that the Company believes enhances the reader’s ability to compare the Company’s gross margin with that of other companies which incur CRT expense and classify it in a manner different than the Company in their statement of earnings. Because securities analysts, investors, lenders and others use gross margin excluding CRT, the Company’s management believes that Mosaic’s presentation of gross margin excluding CRT for Potash affords them greater transparency in assessing Mosaic’s financial performance against competitors. Gross margin excluding CRT, should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.
