Mosaic Updates Calendar Third Quarter 2013 Guidance

             Mosaic Updates Calendar Third Quarter 2013 Guidance

PR Newswire

PLYMOUTH, Minn., Sept. 16, 2013

PLYMOUTH, Minn., Sept. 16, 2013 /PRNewswire/ -- In advance of upcoming
investor conferences, The Mosaic Company (NYSE: MOS) announced today an update
of the near-term price, volume and gross margin guidance, as well as the
Company's effective tax rate guidance for the seven month transition period.

Since the Company announced its calendar third quarter guidance on July 16,
2013, domestic and international crop nutrient markets have softened in part
as a result of the distributors' cautiousness caused by the Belarusian
PotashCompany (BPC) break-up.

"The long-term positive outlook for crop nutrient demand has not changed; high
commodity prices are driving record farm returns and making our products more
affordable than ever before. These strong fundamentals are expected to drive
near record global phosphate and potash shipments in calendar 2013," said Jim
Prokopanko, President and Chief Executive Officer. "In the short term,
however, dealers are cautious and are deferring purchases. As a result, we
have lowered our price and volume guidance for both the Potash and Phosphates
segments for the third calendar quarter of 2013."

In Potash, the revised quarterly guidance range of 1.45 to 1.65 million tonnes
reflects lower near-term demand. The Company's realized price expectations are
now in the range of $330 to $340 per tonne, net of transportation and other
distribution costs. The Potash gross margin rate is now expected to be in the
low to mid 30 percent range.

In Phosphates, distributors' cautious sentiment with respect to potash is
spilling over as buyers are in a wait-and-see mode. The Company has lowered
third calendar quarter 2013 volume guidance to 2.6 to 2.8 million tonnes.
Also, third quarter realized prices are now expected to be in the range of
$430 to $440 per tonne, net of transportation and other distribution costs.
The Phosphates gross margin percentage rate is expected to be in the
mid-teens.

Additionally, the Company now expects its effective tax rate for the seven
month transition period to be in the low 20 percent range.

All other guidance is unchanged.

Jim Prokopanko will discuss the updated guidance and the Company's cost
position in more detail when he presents at the Credit Suisse 26th Annual
Chemical and Ag Science Conference at 9:00 a.m. Eastern Daylight Time on
Tuesday, September 17, 2013. The presentation will also be webcast on the
Company's website at www.mosaicco.com/investors.
