Report on payments to governments for the year ended September 30, 2024

This report provides a consolidated overview of the payments to governments made by Compass Minerals International, Inc. (“CMI,” the parent holding company) and its consolidated subsidiaries for the fiscal year ended September 30, 2024. Unless the context requires otherwise, references in this report to the “Company,” “Compass Minerals,” “CMP,” “we,” “us” and “our” refer to CMI and its consolidated subsidiaries collectively.

All payments are reported in U.S. dollars. Payments that were made in currencies other than in U.S. dollars have been converted to U.S. dollars using the exchange rates as of September 30, 2024.

Our business segments

Our business segments are strategic business units that offer different products and services, and each business requires different technology and marketing strategies. We have two business segments:

Salt Segment: This segment produces and markets salt, consisting primarily of sodium chloride and magnesium chloride, for use in road deicing for winter roadway safety and for dust control, food processing, water softeners and other consumer, agricultural and industrial applications. As of September 30, 2024, the Salt Segment had eight production stage mining properties located in the United States, Canada and the United Kingdom and one exploration stage mining property located in Chile.

Plant Nutrition: This segment produces and markets various grades of potash specialty fertilizer (“SOP”). As of September 30, 2024, the Plant Nutrition segment had one production stage mining property in the United States and one exploration stage mining property in Canada.

Our projects

This report discloses the payments made by us to governments for the commercial development of minerals, such as salt, SOP and magnesium chloride, and which involve the exploration, extraction, processing, and export of such minerals, or the acquisition of a license for any such activity.

As of September 30, 2024, we had eight production stage mining properties. Where the type of resource being commercially developed differed within a mining property, we have disclosed payments for the mining property as separate projects segregated by product type.

Cote Blanche Island: extraction of rock salt, through underground mining, in the state of Louisiana, in the United States. We consider this mining property as one project.




Lyons: brine well-based extraction of mechanically-evaporated salt in the state of Kansas, in the United States. We consider this mining property as one project.

Ogden: extraction of SOP, solar salt and magnesium chloride, through pumping of brine from the Great Salt Lake into solar evaporation ponds on the surface, which we identify as well mining for purposes of this Form SD, in the state of Utah, in the United States. The projects for this mining property include:

Ogden – SOP: extraction of SOP, through solar evaporation.
Ogden – Solar Salt: extraction of solar salt, through solar evaporation.
Ogden – Magnesium Chloride: extraction of magnesium chloride, through solar evaporation.

Pursuant to Item 2.01(b)(1) of Form SD, we are delaying disclosing payment information related to exploratory activities conducted at these two mining properties until our Form SD submitted for the fiscal year ending September 30, 2025, which is the fiscal year immediately following the fiscal year in which payments were made.
