The Mosaic Company

Forward Looking Statements & Non-GAAP Financial Measures

This release contains forward-looking statements within the meaning of the Private

Securities Litigation Reform Act of 1995. Such statements include, but are not limited to,

statements about proposed or pending future transactions or strategic plans and other

statements about future financial and operating results. Such statements are based upon

the current beliefs and expectations of The Mosaic Company’s management and are

subject to significant risks and uncertainties. These risks and uncertainties include, but are

not limited to: the economic impact and operating impacts of the coronavirus (Covid-19)

pandemic, the potential drop in oil demand/production and its impact on the availability

and price of sulfur, political and economic instability in Brazil or changes in government

policy in Brazil, such as higher costs associated with the new mining rules or the

implementation of new freight tables; the predictability and volatility of, and customer

expectations about, agriculture, fertilizer, raw material, energy and transportation markets

that are subject to competitive and other pressures and economic and credit market

conditions; the level of inventories in the distribution channels for crop nutrients; the effect

of future product innovations or development of new technologies on demand for our

products; changes in foreign currency and exchange rates; international trade risks and

other risks associated with Mosaic’s international operations and those of joint ventures in

which Mosaic participates, including the performance of the Wa’ad Al Shamal Phosphate

Company (also known as MWSPC), the timely development and commencement of

operations of production facilities in the Kingdom of Saudi Arabia, and the future success

of current plans for MWSPC and any future changes in those plans; difficulties with

realization of the benefits of our long term natural gas based pricing ammonia supply

agreement with CF Industries, Inc., including the risk that the cost savings initially

anticipated from the agreement may not be fully realized over its term or that the price of

natural gas or ammonia during the term are at levels at which the pricing is

disadvantageous to Mosaic; customer defaults; the effects of Mosaic’s decisions to exit

business operations or locations; changes in government policy; changes in environmental

and other governmental regulation, including expansion of the types and extent of water

resources regulated under federal law, carbon taxes or other greenhouse gas regulation,

implementation of numeric water quality standards for the discharge of nutrients into

Florida waterways or efforts to reduce the flow of excess nutrients into the Mississippi

River basin, the Gulf of Mexico or elsewhere; further developments in judicial or

administrative proceedings, or complaints that Mosaic’s operations are adversely

impacting nearby farms, business operations or properties; difficulties or delays in

receiving, increased costs of or challenges to necessary governmental permits or

approvals or increased financial assurance requirements; resolution of global tax audit

activity; the effectiveness of Mosaic’s processes for managing its strategic priorities;

adverse weather conditions affecting operations in Central Florida, the Mississippi River

basin, the Gulf Coast of the United States, Canada or Brazil, and including potential

hurricanes, excess heat, cold, snow, rainfall or drought; actual costs of various items

differing from management’s current estimates, including, among others, asset retirement,

environmental remediation, reclamation or other environmental regulation, Canadian

resources taxes and royalties, or the costs of the MWSPC; reduction of Mosaic’s available

cash and liquidity, and increased leverage, due to its use of cash and/or available debt

capacity to fund financial assurance requirements and strategic investments; brine inflows

at Mosaic’s Esterhazy, Saskatchewan, potash mine or other potash shaft mines; other

accidents and disruptions involving Mosaic’s operations, including potential mine fires,

floods, explosions, seismic events, sinkholes or releases of hazardous or volatile

chemicals; and risks associated with cyber security, including reputational loss; as well as

other risks and uncertainties reported from time to time in The Mosaic Company’s reports

filed with the Securities and Exchange Commission. Actual results may differ from those

set forth in the forward-looking statements.

This presentation includes the discussion of forward looking EBITDA which is a non-GAAP

financial measure. We are not providing quantitative reconciliation of forward looking

EBITDA because we are unable to predict with reasonable certainty our notable items

without unreasonable effort. Historically, our notable items have included, but are not

limited to, foreign currency transaction gain or loss, unrealized gain or loss on derivatives,

acquisition-related fees, discrete tax items, contingencies and certain other gains or

losses. These items are uncertain, depend on various factors, and could have a material

impact on U.S. GAAP reported results for the guidance period.

Why Soil Health?

Soil health

• Growing food demand necessitates growing productivity on each acre of farmed land

• Changing expectations of society, weather cycles and advanced technologies are driving

new solutions in nutrient use efficiency

• Mosaic’s performance product portfolio and logistics platform enable value creation

for all participants via improved yields, ESG benefits and profitability growth

Growth in the soil health sector and the application of advances in biological science creates

a unique opportunity for Mosaic to build upon a leadership position in balanced crop nutrition.
