Press Release

MOSAIC TO CONTINUE TO SUPPLY POTASH TO POTASHCORP

UNTIL TRIAL BEGINS

PLYMOUTH, Minn., June 30, 2011 – The Mosaic Company (NYSE: MOS) today announced that the Saskatchewan Court of Queen’s Bench has ordered Mosaic to continue to supply potash from its mine at Esterhazy, Saskatchewan, to Potash Corporation of Saskatchewan Inc. (“PCS”) until trial begins, currently scheduled for January 2012. The court’s ruling did not address the merits of any claims in the pending lawsuit between PCS and Mosaic.

Mosaic has provided PCS with potash from Esterhazy, at cost, for approximately 40 years under a tolling agreement. Mosaic notified PCS that, as of May 2011, Mosaic had satisfied its obligation to provide potash to PCS under the agreement. PCS disputes Mosaic’s determination as to when Mosaic’s obligation to provide potash to PCS from the Esterhazy mine expires.

Mosaic believes that PCS’s claims in the lawsuit are without merit and intends to defend vigorously against them.
