The Mosaic Company Announces Closure of Plant City Phosphates Manufacturing Facility

PLYMOUTH, Minn.–(BUSINESS WIRE)–The Mosaic Company (NYSE: MOS) today announced that it will close its
idled Plant City phosphates manufacturing facility in Hillsborough
County, Florida.

The small team of Mosaic employees currently responsible for care and
maintenance activities will remain on site to manage closure and
compliance responsibilities over the next several years.

Operational since 1975, Plant City produced approximately 1.3 million
tonnes of finished phosphates in 2017, its last year of operation. The
plant was idled in late 2017 because it was one of the higher cost
phosphates facilities in Mosaic’s Florida Operations and due to global
phosphate market conditions.

Our decision to close the Plant City phosphate facility reaffirms our
commitment to low-cost operation,” said Mosaic President and CEO Joc
O’Rourke. “We will continue to meet global demand for high-quality
phosphate fertilizers with production from our low-cost facilities in
Florida, Louisiana, Brazil and Peru, and through our joint venture in
Saudi Arabia.”

During the second quarter, Mosaic expects to recognize a notable
non-cash charge of up to $390 million for the permanent closure of the
facility, including asset write-offs and an increase of the asset
retirement obligation liability. Annual cash payments to manage the
closure of the facility over the next five years are expected to be
similar to payments incurred while the plant was idle in 2018. Mosaic
will seek to mitigate a portion of closure costs by evaluating
innovative approaches to water management and to repurposing part of the
facility for productive use.
