(“CMI”), through its subsidiaries (collectively, “CMP,” “Compass Minerals” or the “Company”), is a leading global provider of essential minerals focused on safely delivering where and when it matters to help solve nature’s challenges for customers and communities. The Company’s salt products help keep roadways safe during winter weather and are used in numerous other consumer, industrial, chemical and agricultural applications. Its plant nutrition business is the leading North American producer of sulfate of potash (“SOP”), which is used in the production of specialty fertilizers for high-value crops and turf and helps improve the quality and yield of crops, while supporting sustainable agriculture.

Our next-generation fire retardants help to slow, stop and prevent wildfires through the use of high-performing and environmentally-friendly products. Additionally, the Company has been pursuing the development of a sustainable lithium salt resource to support the North American battery market, although subsequent to September 30, 2023, this project has been suspended indefinitely beyond certain already committed items associated with the early stages of construction of our commercial scale demonstration unit. The Company’s production sites are located in the United States (“U.S.”), Canada and the United Kingdom (“U.K.”).
