                MOSAIC REPORTS FISCAL 2006 FOURTH QUARTER RESULTS

HIGHLIGHTS

     o   The fourth quarter net loss for the period ended May 31, 2006, was
         $180.9 million, or $0.48 per diluted share ("per share"). This
         compares to reported net earnings of $94.1 million or $0.22 per share
         for last year's fourth quarter. Included in the results are:

         o    A charge of $287.6 million pre-tax and $285.6 million after tax,
              or $0.75 per share, from the previously announced restructuring
              of the Phosphates business.

         o    A tax benefit of $81.0 million, or $0.21 per share, related to
              the reduction in Canadian deferred tax liabilities as a result of
              statutory changes in future tax rates in the Province of
              Saskatchewan during the fourth quarter.

         o    Pre-tax foreign currency transaction losses of $34.1 million, or
              $0.05 per share, during the fourth quarter compared with a gain
              of $8.0 million in the prior year period.

     o   Net sales declined 8%, mainly due to lower volumes for phosphates and
         potash. Mosaic's gross margin declined to 12.5% of net sales compared
         to 16.9% a year ago. Margins declined as a result of lower production
         levels and lower high-margin potash sales during the quarter.

     o   The Phosphates business had an operating loss of $268.8 million in the
         fourth quarter, including the restructuring charge, compared with
         operating earnings of $68.8 million for the same period a year ago.

     o   The Potash business had operating earnings of $83.8 million in the
         fourth quarter compared with $118.9 million a year ago as net sales
         declined 23% due to lower volumes.

     o   The Phosphates business is expected to show improved results in fiscal
         2007 due to the completion of the previously announced restructuring
         activities. The Potash business is also expected to improve during the
         second half of calendar 2006 with Canpotex shipments resuming to
         China.

         PLYMOUTH, MN, August 1, 2006 - The Mosaic Company (NYSE: MOS) announced
today a net loss of $180.9 million, or $0.48 per diluted share, for the quarter
ended May 31, 2006. Mosaic's fiscal 2006 net loss was $121.4 million, or $0.35
per share, compared to fiscal 2005 net earnings of $165.6 million or $0.46 per
share.

         Net sales in the fourth quarter were $1.33 billion, a decline of 8%
compared with the same period a year ago. The decline in net sales was mainly
the result of lower sales volumes for the Potash and Phosphates business
segments.



         "Fiscal 2006 was a transition year for Mosaic and we look forward with
confidence to 2007 and beyond. We took aggressive strategic action to
restructure our Phosphates business at the end of the fiscal year to make us
more cost competitive in the global marketplace," said Fritz Corrigan, President
and Chief Executive Officer of Mosaic. "In the Potash business, while markets
have been weak, we expect volumes to improve during the second half of calendar
2006 now that a supply contract has been entered into between Canpotex and
Sinofert in China."

         Mosaic's gross margin for the fourth quarter was $166.2 million
compared with $245.6 million for the same period a year ago. This included
unrealized mark-to-market gains on derivative contracts of $11.2 million
compared with a loss of $4.3 million a year ago. The gross margin as a percent
of sales was 12.5% for the fourth quarter compared with 16.9% a year ago.
Although selling prices were higher for most products, they were more than
offset by an unfavorable sales mix due to lower Potash sales volumes and the
effect of reduced potash and phosphates production levels. In addition,
operating costs were higher resulting from increases in energy-based raw
materials and other input prices.

         Selling, general, and administrative (SG&A) expenses of $54.6 million
were incurred in the fourth quarter, compared to $65.8 million for the same
period a year ago. This decline was mainly because of a one-time $14 million
Brazilian value-added tax (VAT) credit. SG&A costs were adversely affected by
first year Sarbanes-Oxley Section 404 compliance activities.

         Non-cash foreign currency transaction losses totaled $34.1 million for
the fourth quarter compared with a gain of $8.0 million for the same period a
year ago. This was mainly the result of the effect of a strong Canadian dollar
on large U.S. dollar-denominated intercompany receivables held by Mosaic's
Canadian affiliates.

         For the fourth quarter, Mosaic's tax benefit was $61.2 million on a
pre-tax loss of $261.5 million. Mosaic continues to have a high effective
underlying tax rate as a result of losses in the United States and Brazil, and
because its Canadian-based businesses are taxed at relatively higher rates than
the other businesses of the company. Included in the fourth quarter was an $81.0
million tax benefit from the reduction in Canadian deferred tax liabilities as a
result of the statutory reduction in future tax rates in the Province of
Saskatchewan.

         Mosaic ended the quarter with $173.3 million in cash and cash
equivalents. Mosaic's total debt at the end of May 2006 was $2.6 billion,
resulting in a debt-to-capital ratio of 42.6%.

POTASH
         The Potash business segment's total sales volume was 1.7 million tonnes
during the fourth quarter which was 31% lower than last year's fourth quarter
volumes. This was due to a slow North American market as well as a weak export
market, especially in China and India. The average potash selling price
increased to $141 per tonne, up $6 per tonne from the same period a year ago.

         Potash net sales were $328.3 million for the fourth quarter, down 23%
compared with a year ago. The Potash business segment's gross margins declined
to $100.1 million in the fourth quarter or 30.5% of sales, compared with $125.7
million a year ago or 29.7% of sales. This included an unrealized non-cash gain
of $15.2 million resulting from mark-to-market adjustments on derivative
contracts for the fourth quarter compared with a loss of $0.8 million a year
ago. Operating earnings were $83.8 million during the fourth quarter compared to
$118.9 million for the same period last year.

                                                                               2


PHOSPHATES
         The Phosphates business segment's fertilizer and feed shipments were
2.8 million tonnes for the fourth quarter, down 0.6 million tonnes compared with
year ago levels. The average fourth quarter diammonium phosphate (DAP) price
increased by 14% compared with last year to $248 per tonne.

         Phosphates net sales were $805.8 million for the fourth quarter, 1%
lower than the fourth quarter last year. Phosphates' fourth quarter gross margin
was $39.9 million or 5.0% of net sales, compared with $96.5 million or 11.9% of
net sales for the same period a year ago. Operating losses were $268.8 million,
including the Phosphates restructuring charge of $287.6 million, compared with
operating earnings of $68.8 million for the same period a year ago.

         The cost of producing DAP increased 10% in the fourth quarter compared
with the prior year period mainly because of higher energy-based ammonia and
sulfur prices. Operating costs were also higher on a per tonne basis as Mosaic
operated its mining and production facilities at lower rates during this period.

OFFSHORE
         Mosaic's Offshore business segment's net sales were $236.8 million for
the fourth quarter, an increase of 8% compared with last year. Offshore's fourth
quarter operating earnings were $10.5 million compared to a loss of $5.8 million
for the comparable period last year. The increase in fourth quarter operating
earnings was the result of a Brazilian VAT credit. Offshore results continued to
be negatively affected by poor farm economics in Brazil.

NITROGEN
         Mosaic's Nitrogen business segment's fourth quarter operating earnings
were $4.7 million compared to $3.5 million for the fourth quarter a year ago.

EQUITY EARNINGS
         Total equity earnings in non-consolidated subsidiaries were $19.4
million for the quarter, an increase of $8.1 million compared with last year's
results for the same period. Mosaic's equity earnings from its investment in
Saskferco were $10.7 million for the fourth quarter compared with $6.8 million a
year ago. Mosaic's equity earnings from Fosfertil were $3.3 million for the
fourth quarter compared to $4.7 million last year.

FISCAL 2006
         Net sales increased 21% to $5.3 billion for fiscal 2006 mainly as a
result of the business combination that formed Mosaic in October 2004 along with
higher prices for phosphates and potash products. Gross margin also increased
$111.9 million to $637.4 million, which was 12% of net sales. Higher prices were
offset by increased costs of production. Operating earnings were $105.8 million
in fiscal 2006, including the $287.6 million Phosphates restructuring charge,
compared with $318.5 million in fiscal 2005. There was a foreign currency
transaction loss of $100.6 million in fiscal 2006, or $0.15 per share, compared
with a gain of $13.9 million a year ago, primarily as a result of a strong
Canadian dollar and large U.S. dollar-denominated inter-company receivables held
by Mosaic's Canadian affiliates. The equity in net earnings of non-consolidated
companies was $48.4 million, a decline of $7.5 million compared with the prior
year due to weaker results from Fosfertil. Dividends from non-consolidated
companies totaled $26.7 million in fiscal 2006.

                                                                               3


         As of the end of fiscal 2006, Mosaic had surpassed its synergy benefits
goal from the business combination between IMC Global and Cargill's Crop
Nutrition businesses of $145 million calculated on an annual run-rate basis.
Synergy benefits include cost reduction and cost avoidance initiatives,
production volume enhancement efforts, opportunity savings, capital spending
avoidance and other classifications. In fiscal 2006, the benefits of the
synergies have been significantly offset by higher costs for energy and other
production inputs, wages and benefits, water treatment, raw material inputs,
general inflation and one-time costs to achieve them.

OBSERVATIONS AND OUTLOOK
         "We are encouraged by more attractive industry fundamentals in our
Phosphates and Potash businesses as well as the expected benefits of our
Phosphates restructuring, which should result in lower costs of production and
higher margins in fiscal 2007," Corrigan said. "We expect Potash volumes to
recover during the second half of calendar 2006 now that contracts have been
signed between Canpotex and Sinofert, a key Chinese customer. We believe that
inventory levels throughout the potash distribution pipeline, including China
and India, have been sharply reduced."

         For Phosphates, fiscal 2007 sales volumes are expected to range from
9.5 to 9.9 million tonnes, including 0.9 millions tonnes of feed phosphates.
Phosphates margins are expected to benefit from cost declines due to
expectations of lower raw material prices. Potash sales volumes for fiscal 2007
are anticipated to be between 7.7 and 8.1 million tonnes taking into account
resumed shipments by Canpotex to China in August 2006.

         In July, Mosaic's single super phosphate (SSP) plant in Quebracho,
Argentina began production and is expected to produce up to 240,000 tonnes of
granular SSP annually.

         Mosaic anticipates capital spending ranging between $250 million and
$290 million during fiscal 2007 compared with $389.5 million in fiscal 2006.
This reduced level of capital spending is primarily a result of the Phosphates
restructuring.

         Mosaic expects to record a tax benefit of $45 to $50 million in the
first quarter of fiscal 2007 as a result of a reduction in future Canadian
Federal tax rates, which leads to a reduction in deferred tax liabilities. This
is similar in nature to the benefit recorded in the fourth quarter from a
reduction in the Saskatchewan Provincial tax rate. As they are implemented,
these tax rate changes will result in a lower effective tax rate for Mosaic.

* Interest expense is exclusive of amortization of debt financing fees and

The Company has presented above EBITDA and Adjusted EBITDA. EBITDA and Adjusted
EBITDA are non-GAAP financial measures. 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 generally accepted accounting principles
("GAAP"). EBITDA and Adjusted EBITDA are not measures of financial performance
under U.S. GAAP. Because not all companies use identical calculations, our
calculation of EBITDA may not be comparable to other similarly titled measures
presented by other companies. Moreover, EBITDA as presented in this press
release is different than similarly titled measures used for purposes of
financial covenants in our senior secured bank credit facility and other
covenants relating to our indebtedness, all of which require different
adjustments, both positive and negative, that were the result of negotiations
with the lenders. In addition, Adjusted EBITDA, which we present above, excludes
restructuring and other charges related to the restructuring of our Phosphates
business. The Restructuring and other charges are not items that are generally
excluded from EBITDA. In evaluating these measures, investors should consider
that our methodology in calculating such measures may differ from that used by
other companies.

                                                                               8


EBITDA, or various adjusted measures of EBITDA, is frequently used by securities
analysts, investors, lenders and others to evaluate companies' performance,
including, among other things, cash flows and profitability before the effect of
financing and similar decisions. Because securities analysts, investors, lenders
and others use EBITDA, Mosaic's management believes that our presentation of
EBITDA affords them greater transparency in assessing our financial performance.
We believe that Adjusted EBITDA is useful to investors because, when presented
with EBITDA, it highlights the extent to which EBITDA in fiscal 2006 and our
fourth fiscal quarter was affected by our decision to restructure our Phosphates
business. EBITDA and Adjusted EBITDA should not be considered as a substitute
for, nor superior to, measures of financial performance prepared in accordance
with GAAP.
