Phosphates Segment

Our Phosphates business segment owns and operates mines and production facilities in Florida which produce concentrated phosphate crop nutrients and phosphate-based animal feed ingredients, and processing plants in Louisiana which produce concentrated phosphate crop nutrients. We have a 75%economic interest in the Miski Mayo Phosphate Mine in Peru (“Miski Mayo Mine”), which is included in the results of our Phosphates segment.

The following map shows the locations of each of our phosphate concentrates plants in the U.S. and each of our active, temporarily idled, and planned phosphate mine locations, including beneficiation plants, in Florida. The reserves associated with our Ona, Florida location have been allocated to other active mines based on our future mining plans:

U.S. Phosphate Crop Nutrients and Animal Feed Ingredients

Our U.S. Phosphates operations have capacity to produce approximately 4.5 million tonnes of phosphoric acid (“P 2 O 5”) per year, or about 7% of world annual capacity and about 60% of North American annual capacity. P 2 O 5 is produced by reacting finely ground phosphate rock with sulfuric acid. P 2 O 5 is the key building block for the production of high analysis or concentrated phosphate crop nutrients and animal feed products and is the most comprehensive measure of phosphate capacity and production and a commonly used benchmark in our industry. Our U.S. P 2 O 5 production totaled approximately 2.9 million tonnes during 2024. Our U.S. operations account for approximately 6% of estimated global annual production and 53% of estimated North American annual output of P 2 O 5.

Our phosphate crop nutrient products are marketed worldwide to crop nutrient manufacturers, distributors, retailers and farmers. Our principal phosphate crop nutrient products are:

Diammonium Phosphate (18-46-0): Diammonium Phosphate (“DAP”) is the most widely used high-analysis phosphate crop nutrient worldwide. DAP is produced by first combining phosphoric acid with anhydrous ammonia in a reaction vessel. This initial reaction creates a slurry that is then pumped into a granulation plant where it is reacted with additional ammonia to produce DAP. DAP is a solid granular product that is applied directly or blended with other solid plant nutrient products, such as urea and potash.

Monoammonium Phosphate (11-52-0): Monoammonium Phosphate (“MAP”) is the second most widely used high-analysis phosphate crop nutrient. MAP is also produced by first combining phosphoric acid with anhydrous ammonia in a reaction vessel. The resulting slurry is then pumped into the granulation plant where it is reacted with additional P 2 O 5 to produce MAP. MAP is a solid granular product that is applied directly or blended with other solid plant nutrient products.

MicroEssentials® is a value-added ammoniated phosphate product that is enhanced through a patented process that creates very thin platelets of sulfur and other micronutrients, such as zinc, on the granulated product. The patented process incorporates both the sulfate and elemental forms of sulfur, providing season-long availability to crops.

Production of our animal feed ingredients products is located at our New Wales, Florida facility. We market our feed phosphate primarily under the leading brand names of Biofos® and Nexfos®.

Annual capacity by plant as of December 31, 2024 and production volumes by plant for 2024 are listed below:

(tonnes in millions) · Phosphoric Acid · Processed Phosphate(a)/DAP/MAP/ MicroEssentials®/Feed Phosphate

(a)Our ability to produce processed phosphate has been less than our annual operational capacity stated in the table above, except to the extent we purchase P 2 O 5. Factors affecting actual production are described in note (c) below.

(b)Operational capacity is our estimated long-term capacity based on an average amount of scheduled down time, including maintenance and scheduled turnaround time, and product mix, and no significant modifications to operating conditions, equipment or facilities.

(c)Actual production varies from annual operational capacity shown in the above table due to factors that include, among others, the level of demand for our products, maintenance and turnaround time, accidents, mechanical failure, product mix, and other operating conditions.

The P 2 O 5 produced at Uncle Sam is shipped to Faustina, where it is used to produce DAP, MAP and MicroEssentials®. Our Faustina plant also manufactures ammonia that is mostly consumed in our concentrate plants.

We produced approximately 6.3 million tonnes of concentrated phosphate crop nutrients during 2024 and accounted for approximately 66% of estimated North American annual production.

Phosphate Rock

Phosphate rock is the key mineral used to produce phosphate crop nutrients and feed phosphate. Our Florida phosphate rock mines produced approximately 8.9 million tonnes in 2024 and accounted for approximately 47% of estimated North American annual production. We are the world’s second largest miner of phosphate rock (excluding China) and currently operate four mines in North America with a combined annual capacity of 17.2 million tonnes. Additionally, we own 75% of the Miski Mayo Mine, which has an annual capacity of 4.8 million tonnes. Production of one tonne of DAP requires between 1.6 and 1.7 tonnes of phosphate rock.

All of our wholly-owned phosphate mines and related mining operations in North America are located in central Florida. During 2024, we operated three active mines in Florida: Four Corners, South Fort Meade and Wingate. We plan to explore and develop the DeSoto property and the South Pasture property, which was previously idled, to offset future depletion at our Florida properties. We have a 75% economic interest in the Miski Mayo Mine, which allows us to supplement our other produced rock to meet our overall fertilizer production needs and is the primary source of rock for our Louisiana operations. We have the right to use or sell to third parties 75% of the Miski Mayo Mine’s annual production.

See “Item 2. Properties” for a discussion of our phosphate mining properties, including processing methods, facilities, production and summaries of our mineral resources and reserves, both in the aggregate and for our individual material phosphate mining properties.

Sulfur

We use molten sulfur at our phosphate concentrates plants to produce sulfuric acid, primarily for use in our production of P 2 O 5. We purchased approximately 3.0 million long tons of sulfur during 2024. We purchase the majority of this sulfur from North American oil and natural gas refiners who are required to remove or recover sulfur during the refining process. Production of one tonne of DAP requires approximately 0.40 long tons of sulfur. We procure our sulfur from multiple sources and receive it by truck, rail, barge and vessel, either directly at our phosphate plants or have it sent for gathering to terminals that are located on the U.S. gulf coast. In addition, we use formed sulfur received through Tampa, Florida ports, which are delivered by truck to our New Wales facility and melted through our sulfur melter.

We own and operate sulfur terminals in Riverview and Tampa, Florida, along with Galveston, Texas and Faustina, Louisiana. We also lease terminal space in Beaumont, Texas. We have long-term time charters on two ocean-going tugs/barges and one ocean-going vessel that transports molten sulfur from the Texas terminals to Tampa. We then further transport by truck to our Florida phosphate plants. Our sulfur logistic assets also include a large fleet of leased railcars that supplement our marine sulfur logistic system. Our Louisiana operations are served by truck from nearby refineries.

Although sulfur is readily available from many different suppliers and can be transported to our phosphate facilities by a variety of means, sulfur is an important raw material used in our business that has in the past been, and may in the future, be the subject of volatile pricing and availability. Alternative transportation and terminaling facilities might not have sufficient capacity to fully serve all of our facilities in the event of a disruption to current transportation or terminaling facilities. Changes in the price of sulfur or disruptions to sulfur transportation or terminaling facilities could have a material impact on our business. We have included a discussion of sulfur prices in our Management’s Analysis.

Ammonia

We use ammonia together with P 2 O 5 to produce DAP, MAP and MicroEssentials®. We consumed approximately 1.0 million tonnes of ammonia during 2024. Production of one tonne of DAP requires approximately 0.23 tonnes of ammonia. We purchase approximately one-third of our ammonia from various suppliers in the spot market with the remaining two-thirds either purchased through our ammonia supply agreement (the “CF Ammonia Supply Agreement”) with an affiliate of CF Industries Inc. (“CF”) or produced internally at our Faustina, Louisiana location.

Our Florida ammonia needs are currently supplied under multi-year contracts with both domestic and offshore producers. Ammonia for our Florida plants is terminaled through owned ammonia facilities at the Port of Tampa and Port Sutton, Florida. Ammonia is transported by pipeline from the terminals to our production facilities. We have service agreements with the operators of the pipelines for Bartow, New Wales and Riverview, which provide service through June 30, 2025 with two year auto-renewal provisions unless either party objects.

Under the CF Ammonia Supply Agreement, we purchased 556,232 metric tonnes in 2024. This contract terminated effective January 1, 2025. We now have agreements with various suppliers to ensure we have reliable sources of supply for ammonia to support competitive pricing in various market conditions.

We produce ammonia at Faustina, Louisiana primarily for our own consumption. Our annual capacity is approximately 530,000 tonnes. From time to time, we sell surplus ammonia to unrelated parties and/or may transport surplus ammonia to the Port of Tampa. In certain circumstances, we source ammonia from alternative sources to receive at Faustina.

Although ammonia is readily available from many different suppliers and can be transported to our Phosphates facilities by a variety of means, ammonia is an important raw material used in our business that has in the past been, and may in the future be, the subject of volatile pricing. In addition, alternative transportation and terminaling facilities might not have sufficient capacity to fully serve all of our facilities in the event of a disruption to existing transportation or terminaling facilities. Changes in the price of ammonia or disruptions to ammonia transportation or terminaling could have a material impact on our business. We have included a discussion of ammonia prices in our Management’s Analysis.

Natural Gas for Phosphates

Natural gas is the primary raw material used to manufacture ammonia. At our Faustina facility, ammonia is manufactured on site. The majority of natural gas is purchased through firm delivery contracts based on published index-based prices and is sourced from Texas and Louisiana via pipelines interconnected to the Henry Hub. We use over-the-counter swap and/or option contracts to forward price portions of future natural gas purchases. We typically purchase approximately 12.0 million MM BTU of natural gas per year for use in ammonia production at Faustina.

Our ammonia requirements for our Florida operations are purchased rather than manufactured on site. Therefore, while we typically purchase approximately 3.2 million MM BTU of natural gas per year in Florida, it is only used as a thermal fuel for various phosphate production processes.

Florida Land Holdings

We are a significant landowner in the State of Florida, which has in the past been considered one of the fastest areas of population growth in the U.S. We have land holdings totaling over 368,000 acres. These land holdings give Mosaic access to phosphate rock reserves and exist as fee simple, mining agreements or mineral rights. Some of our land holdings are needed to operate our Phosphates business, while a portion of our land assets, such as certain reclaimed properties, are no longer required for our ongoing operations. As a general matter, more of our reclaimed property becomes available for uses other than for phosphate operations each year. Our real property assets are generally comprised of concentrates plants, port facilities, phosphate mines and other property which we have acquired through our presence in Florida. Our long-term future land use strategy is to optimize the value of our land assets.

Potash Segment

We are one of the leading potash producers in the world. We mine and process potash in Canada and the U.S. and sell potash in North America and internationally. The term “potash” applies generally to the common salts of potassium. Muriate of potash (“MOP”) is the primary source of potassium for the crop nutrient industry. Red MOP has traces of iron oxide. The granular and standard grade red MOP products are well suited for direct fertilizer application and bulk blending. White MOP has a higher percent potassium oxide (“K 2 O”). White MOP, besides being well suited for the agricultural market, is used in many industrial applications. We also produce a double sulfate of potash magnesia product, which we market under our brand name K-Mag®, at our Carlsbad, New Mexico facility.

Our potash products are marketed worldwide to crop nutrient manufacturers, distributors and retailers and are also used in the manufacturing of mixed crop nutrients and, to a lesser extent, in animal feed ingredients. We also sell potash to customers for industrial use. In addition, our potash products are used for de-icing and as a water softener regenerant.

In 2024, we operated three potash mines in Canada, including two shaft mines and one solution mine, as well as one potash shaft mine in the U.S. Esterhazy, the largest potash mine in the world, has completed full ramp up of capacity and production. The K3 mine shaft expansion has been supplying the capacity and production needed since the closure of the K1 and K2 shafts in the second quarter of 2021. Decommissioning of the K1 and K2 shafts at our Esterhazy, Saskatchewan mine was completed in 2022.

Mosaic leases approximately 291,500 acres of mineral rights from the government of Saskatchewan, and approximately 99,700 acres of freehold mineral rights in the Kronau/Regina area, which have not been developed.

We pay Canadian resource taxes consisting of the Potash Production Tax and resource surcharge. The Potash Production Tax is a Saskatchewan provincial tax on potash production and consists of a base payment and a profits tax. We also pay a percentage of the value of resource sales from our Saskatchewan mines. In addition to the Canadian resource taxes, royalties are payable to the mineral owners in respect of potash reserves or production of potash. We have included a further discussion of the Canadian resource taxes and royalties in our Management’s Analysis.

The map below shows the location of each of our potash properties in North America:

Our North American potash annualized operational capacity totals 11.5 million tonnes of product per year and accounts for approximately 14% of world annual capacity and 41% of North American annual operational capacity. Production during 2024 totaled 8.8 million tonnes. We account for approximately 12% of estimated world annual production and 35% of estimated North American annual production.

The following table shows, for each of our potash mines, annual capacity as of December 31, 2024 and finished product output for 2024:

(b)Actual production varies from annual operational capacity shown in the above table due to factors that include, among others, the level of demand for our products, maintenance and turnaround time, the quality of the reserves and the nature of the geologic formations we are mining at any particular time, accidents, mechanical failure, product mix and other operating conditions.

(c)Represents full capacity assuming no turnaround or maintenance time.

(d)The annualized proven peaking capacity shown above is the capacity currently used to determine our share of Canpotex, Limited (“Canpotex”) sales. Canpotex members’ respective shares of Canpotex sales are based upon the members’ respective proven peaking capacities for producing potash. When a Canpotex member expands an existing mine, the new capacity is added to that member’s proven peaking capacity based on either a 90-day production run at the maximum production levels or an engineering audit of the expansion performed by an independent engineering firm in accordance with approved protocols. The annual operational capacity of a mine reported in the table above can exceed the annualized proven peaking capacity until the proving run or engineering audit has been completed. Our current entitlement percentage of Canpotex is 36.2%, however in 2024, our percentage was 34.5% due to lower shipments as a result electrical equipment problems.

(e)Annual operational capacity is our estimated potash production capacity based on the quality of reserves and the nature of the geologic formations expected to be mined, milled and/or processed over the long term, average amount of scheduled down time, including maintenance and scheduled turnaround time, and product mix, and no significant modifications to operating conditions, equipment or facilities. Operational capacities will continue to be updated to the extent new production results impact ore grades assumptions.

(f)Our Colonsay mine operates as a swing mine to meet market demands. We have the ability to reach an annual operating capacity of 2.1 million tonnes over time by increasing our staffing levels and investment in mine development activities.

(g)Following completion of our Esterhazy K3 expansion project, a third-party audit assessed our Esterhazy Facility's nameplate capacity at 7.8 million tonnes. To date, we have been unable to rely upon this audit as a basis for an increase to our Canpotex entitlement percentage. We are evaluating when to take the necessary steps to complete the entitlement adjustment process.

(h)K-Mag® is a specialty product that we produce at our Carlsbad facility.

See Item 2. “Properties” for a discussion of our potash mining properties, including processing methods, facilities, production and summaries of our mineral resources and reserves, both in the aggregate and for our individual material potash mining properties.

Natural Gas

Natural gas is used at our Belle Plaine solution mine as a fuel to produce steam and to dry potash products. The steam is used to generate electricity and provide thermal energy to the evaporation, crystallization and solution mining processes. The Belle Plaine solution mine typically accounts for approximately 80% of our Potash segment’s total natural gas requirements for potash production. At our shaft mines, natural gas is used as a fuel to heat fresh air supplied to the shaft mines and for drying potash products. Combined natural gas usage for both the solution and shaft mines totaled 17.2 million MM BTU during 2024. We purchase our natural gas requirements on firm delivery index price-based physical contracts and on short-term spot-priced physical contracts. Our Canadian operations purchase physical natural gas from companies in Alberta and Saskatchewan using AECO price indices references and transport the gas to our plants via the TransGas pipeline system. The

U.S. potash operation in New Mexico purchases physical gas in the southwest respective regional market using the El Paso San Juan Basin market pricing reference. We use financial derivative contracts to manage the pricing on portions of our natural gas requirements.

Mosaic Fertilizantes Segment

Our Mosaic Fertilizantes segment owns and operates mines, chemical plants, crop nutrient blending and bagging facilities, port terminals and warehouses in Brazil and Paraguay, which produce and sell concentrated phosphate crop nutrients, phosphate-based animal feed ingredients and potash fertilizer. The following map shows the locations of our operations in Brazil and Paraguay:

We are the largest producer and one of the largest distributors of blended crop nutrients for agricultural use in Brazil. We produce and sell phosphate- and potash-based crop nutrients, and animal feed ingredients through our operations. Our operations in Brazil include five phosphate mines, four chemical plants and a potash mine. We own and operate ten blending plants in Brazil and one blending plant and port in Paraguay. We are currently constructing a one million tonne distribution facility in northern Brazil in Palmeirante. In addition, we lease several other warehouses and blending units depending on sales and production levels. We also have a 62% ownership interest in Fospar, S.A. (“Fospar”). Fospar owns and operates an SSP (defined below) granulation plant, which produces approximately 0.5 million tonnes of SSP per year, and a deep-water port and throughput warehouse terminal facility in Paranagua, Brazil. The port facility at Paranagua handles approximately

3.6 million tonnes of imported crop nutrients. In 2024, Mosaic Fertilizantes sold approximately 9.0 million tonnes of crop nutrient products and accounted for approximately 18% of fertilizer shipments in Brazil.

We have the capability to annually produce approximately 4.5 million tonnes of phosphate- and potash-based crop nutrients and animal feed ingredients. Crop nutrient products produced are marketed to crop nutrient manufacturers, distributors, retailers and farmers.

In addition to producing crop nutrients, Mosaic Fertilizantes purchases phosphate, potash and nitrogen products which are either used to produce blended crop nutrients (“Blends”) or for resale. In 2024, Mosaic Fertilizantes purchased 1.2 million tonnes of phosphate-based products, primarily MicroEssentials®, from our Phosphates segment, and 2.2 million tonnes of potash products from our Potash segment and Canpotex.

Phosphate Crop Nutrients and Animal Feed Ingredients

Our Brazilian phosphate operations have capacity to produce approximately 1.1 million tonnes of P 2 O 5 per year, or about 62% of Brazilian annual capacity. Phosphoric acid is produced by reacting ground phosphate rock with sulfuric acid. P 2 O 5 is the key building block for the production of high analysis or concentrated phosphate crop nutrients and animal feed products and is the most comprehensive measure of phosphate capacity and production and a commonly used benchmark in our industry. Our Brazilian phosphoric acid production totaled approximately 1.0 million tonnes in 2024 and accounted for approximately 89% of Brazilian annual output.

Our principal phosphate crop nutrient products are:

Monoammonium Phosphate (11-52-0) (“MAP”): MAP is a crop nutrient composed of two macronutrients, nitrogen and phosphoric acid. This slurry is added inside a rotary drum type granulator with ammonia to complete the neutralization reaction and produce MAP.

Triple superphosphate (“TSP”): TSP is a highly concentrated phosphate crop nutrient. TSP is produced from the phosphate rock reaction with phosphoric acid in a kuhlmann type reactor. The process for the production of TSP in Brazil is run of pile where the product undergoes a curing process of approximately seven days for later granulation.

Single superphosphate (“SSP”): SSP is a crop nutrient with a low concentration of phosphorus that is used in agriculture because of the sulfur content in its formulation. SSP is produced from mixing phosphate rock with sulfuric acid in a kuhlmann or malaxador type reactor. After the reaction, the product goes to the curing process and then feeds the granulation units.

Dicalcium phosphate (“DCP”): Dicalcium phosphate is produced by the reaction of desulphurized phosphoric acid with limestone. At Uberaba, it is produced from the reaction of concentrated phosphoric acid with limestone slurry. At Cajati, the phosphoric acid is diluted with dry limestone. The reaction of the DCP occurs in a kuhlmann or spinden type reactor.

Our primary mines and chemical plants are located in the states of Minas Gerais, São Paulo, and Goias. Production of our animal feed ingredients products is located at our Uberaba, Minas Gerais and Cajati, São Paulo facilities. We market our feed phosphate primarily under the brand name Foscálcio.

Annual capacity and production volume by plant as of December 31, 2024 are listed below:

Total1.11.04.03.1

(a)Our ability to produce processed phosphate has been less than our annual operational capacity as stated in the table above, except to the extent we purchase phosphoric acid. Factors affecting actual production are described in note (c) below.

(b)The annual production capacity was calculated using the hourly capacity, days stopped for annual maintenance and OEE (historical utilization factor and capacity factor).

(c)Actual production varies from annual operational capacity shown in the table above due to factors that include, among others, the level of demand for our products, maintenance and turnaround time, accidents and mechanical failure.

The phosphoric acid produced at Cajati is used to produce DCP. The phosphoric acid produced at Uberaba is used to produce MAP, TSP and DCP.

We produced approximately 2.6 million tonnes of concentrated phosphate crop nutrients during 2024 which accounted for approximately 48% of estimated Brazilian annual production.

Phosphate Rock

Phosphate rock is the key mineral used to produce phosphate crop nutrients and animal feed product. Our phosphate rock production in Brazil totaled approximately 3.9 million tonnes in 2024, which accounted for approximately 74% of estimated Brazilian annual production. We are the largest producer of phosphate rock in Brazil and currently have an annual capacity of approximately 4.6 million tonnes. During 2024, we operated five properties; Araxá, Patrocínio and Tapira in the state of Minas Gerais; Catalão in the state of Goiás; and Cajati in the state of São Paulo.

Production of one tonne of MAP requires 1.6 to 1.7 tonnes of phosphate rock. Production of one tonne of SSP requires between 0.6 to 0.7 tonnes of phosphate rock. Production of one tonne of TSP requires 1.4 tonnes of phosphate rock.

See Item 2. “Properties” for a discussion of our Brazilian mining properties, including processing methods, facilities, production and summaries of our mineral resources and reserves, both in the aggregate and for our individually material Brazilian properties.

We are required to pay royalties to mineral owners and resource taxes to the Brazilian government for phosphate and potash production. The resource taxes, known as Compensação Financeira pela Exploração de Recursos Minerais or CFEM, are regulated by the National Mining Agency. In 2024, we paid royalties and resource taxes of approximately $22.1 million.

Sulfur

We use molten sulfur at our phosphate concentrates plants to produce sulfuric acid, one of the key components used in the production of phosphoric acid. We consumed approximately 1.0 million long tons of sulfur for our own production during 2024. We purchase approximately 14% of the volume under annual supply agreements from oil and natural gas refiners, who are required to remove or recover sulfur during the refining process. The remaining 86% is purchased in the spot market. Sulfur is imported through the Tiplam port and transported by rail to the Uberaba plant and by truck to the Araxá and Cajati locations.

Although sulfur is readily available from many different suppliers and can be transported to our phosphate facilities by a variety of means, sulfur is an important raw material used in our business that has in the past been, and could in the future be, subject to volatile pricing and availability. Alternative transportation and terminaling facilities might not have sufficient capacity to fully serve all of our facilities in the event of a disruption to current transportation or terminaling facilities. Changes in the price of sulfur or disruptions to sulfur transportation or terminaling facilities could have a material impact on our business.

Ammonia

We use ammonia, together with phosphoric acid, to produce MAP, and to a lesser extent for SSP production. We consumed approximately 118,280 tonnes of ammonia during 2024. Production of one tonne of MAP requires approximately 0.137 tonnes of ammonia. We purchase all of our ammonia under a long-term supply agreement with two suppliers. Ammonia is imported through the Tiplam port and transported by truck to Uberaba, Araxá and Catalão.

We own approximately 1% of the Tiplam terminal in Santos, São Paulo. Our ownership percentage, along with a contractual agreement, guarantee us unloading priority for ammonia and also provide us unloading capacity for rock, sulfur and crop nutrients.

Although ammonia is readily available from many different suppliers and can be transported to our phosphates facilities by a variety of means, ammonia is an important raw material used in our business that has in the past been, and in the future could be, subject to volatile pricing. Alternative transportation and terminaling facilities might not have sufficient capacity to fully serve all of our facilities in the event of a disruption to existing transportation or terminaling facilities. Changes in the price of ammonia or disruptions to ammonia transportation or terminaling could have a material impact on our business.

Brazilian Potash

We conduct potash operations through the leased Taquari-Vassouras shaft mine, which is the only potash mine in Brazil, located in Rosário do Catete in the Brazilian state of Sergipe. We also own a related refinery at the site. We produce and sell potash product domestically. MOP is the primary source of potassium for the crop nutrient industry in Brazil. Red MOP has traces of iron oxide. The granular and standard grade red MOP products are well-suited for direct fertilizer application and bulk blending. Our potash product is marketed in Brazil to crop nutrient manufacturers, distributors and retailers and is also used in the manufacturing of crop nutrients.

In 2024, we paid royalties of approximately $6.8 million related to the leasing of potash assets and mining rights for Taquari.

Land Holdings

Mosaic Fertilizantes owns properties and the surface rights of certain rural lands comprising over 34,000 hectares (84,000 acres) in the States of São Paulo, Minas Gerais, Goiás, Paraná, Mato Grosso, Santa Catarina, Bahia and Sergipe, and has the right to mine additional properties which contain phosphate rock or potash reserves. Most of our land holdings are needed to operate our phosphate and potash production and fertilizer distribution businesses. A portion of our land assets may no longer be required for our current operations and may be leased to third parties, for agricultural or other purposes, or may be set aside for mineral or environmental conservation. Our real property assets are generally comprised of concentrates plants, port facilities and phosphate and potash mines, crop nutrient blending and bagging facilities and other properties which we have acquired through our presence in Brazil.

India and China Distribution Businesses

Our China and India distribution businesses market phosphate-, potash- and nitrogen-based crop nutrients and provide other ancillary services to wholesalers, cooperatives, independent retailers, and farmers in the Asia-Pacific regions. These operations provide our Phosphates and Potash segments access to key markets outside of North and South America and serve as a marketing agent for our Phosphates segment. In 2024, the India and China operations purchased 25,233 tonnes of phosphate-based products from our Phosphates segment, and 1,077,567 tonnes of potash products from our Potash segment and Canpotex. They also purchase phosphate, potash and nitrogen products from unrelated third parties, which we either use to produce blended crop nutrients or for resale.

In China, we own two 300,000-tonne per year capacity blending plants. In 2024, we sold approximately 325,000 tonnes of Blends and distributed another 850,000 tonnes of phosphate and potash crop nutrients in China.

In India, we have distribution facilities to import and sell crop nutrients. In 2024, we distributed approximately 201,000 tonnes of potash crop nutrient products in India.
