SUMMARY OVERVIEW OF MINING OPERATIONS

Information concerning our mining properties in this Form 10-K has been prepared in accordance with the requirements of subpart 1300 of Regulation S-K. When evaluating materiality for purposes of the disclosure, the Company considered several quantitative metrics including production, sales and capital expenditure data, as well as synergistic and other qualitative information that the Company believes investors would find important to their investing decisions.

The rest of Item 2

As used in this Form 10-K, the terms “mineral resource,” “measured mineral resource,” “indicated mineral resource,” “inferred mineral resource,” “mineral reserve,” “proven mineral reserve” and “probable mineral reserve” are defined and used in accordance with subpart 1300 of Regulation S-K. Under subpart 1300 of Regulation S-K, mineral resources may not be classified as “mineral reserves” unless the determination has been made by a qualified person (“QP”) that the mineral resources can be the basis of an economically viable project. You are specifically cautioned not to assume that any part or all of the mineral deposits (including any mineral resources) in these categories will ever be converted into mineral reserves, as defined by the SEC. See Item 1A, “Risk Factors.”

You are cautioned that, except for that portion of mineral resources classified as mineral reserves, mineral resources do not have demonstrated economic value. Inferred mineral resources are estimates based on limited geological evidence and sampling and have a too high of a degree of uncertainty as to their existence to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Estimates of inferred mineral resources may not be converted to a mineral reserve. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. A significant amount of exploration must be completed in order to determine whether an inferred mineral resource may be upgraded to a higher category. Therefore, you are cautioned not to assume that all or any part of an inferred mineral resource exists, that it can be the basis of an economically viable project, or that it will ever be upgraded to a higher category. Likewise, you are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted to mineral reserves. See Item 1A, “Risk Factors.”

The Company has determined that the following properties are individually material mining properties for purposes of subpart 1300 of Regulation S-K: the Ogden facility, the Cote Blanche mine and the Goderich mine. There have been no material changes in the mineral reserves or mineral resources from the last technical report summaries filed for each of the other properties, so the Company is not filing a new technical report summary for any of these properties in connection with this Form 10-K.

31 · 2025 FORM 10-K

The following map shows the locations of our mining properties, as of September 30, 2025:

32 · 2025 FORM 10-K

As of September 30, 2025, we had ten mining properties, as summarized in the table below:

Location · Segment · Use · Stage

Cote Blanche Island, Louisiana · Salt · Rock salt mine · Production

Lyons, Kansas · Salt · Evaporated salt facility · Production

Ogden, Utah · Salt, Plant Nutrition · SOP, solar salt and magnesium chloride facility · Production

Amherst, Nova Scotia · Salt · Evaporated salt facility · Production

Unity, Saskatchewan · Salt · Evaporated salt facility · Production

Wynyard, Saskatchewan · Plant Nutrition · SOP facility · Exploration

Winsford, Cheshire · Salt · Rock salt mine · Production

Atacama Desert · Salt · N/A · Exploration

We are the sole operator of each of our mining properties and we own all of the ownership interests in our mining operations. With respect to most of our mineral properties, we own the land and surface rights and have entered into lease agreements with respect to the mineral rights. Our mineral leases have varying terms. Some will expire after a set term of years, while others continue indefinitely. Many of these leases provide for a royalty payment to the lessor based on a specific amount per ton of minerals extracted or as a percentage of revenue. In addition, we own a number of properties and are party to non-mining leases that permit us to perform activities that are ancillary to our mining operations, such as surface use leases for storage at depots and warehouse leases. We believe that all of our leases were entered into at market terms.

We hold numerous environmental and mineral extraction permits, water rights and other permits, licenses and approvals from governmental authorities authorizing operations at each of our facilities. With respect to each facility at which we produce salt, brine or SOP, permits, licenses and approvals are obtained as needed in the normal course of business based on our mine plans and federal, state, provincial and local regulatory provisions regarding mine permitting and licensing. Based on our historical permitting experience, we expect to be able to continue to obtain necessary mining permits and approvals to support historical rates of production.

The three processing methods we use to produce salt and SOP at our production-stage properties are as follows:

Production methods and facilities

Underground salt mining

Underground salt mining produces rock salt using both drill-and-blast and continuous mining techniques in deep deposits. Compass Minerals is the largest rock salt producer in North America and the U.K. It operates underground salt mines at Goderich, Ontario, the largest salt mine in the world with an annual capacity of 9 million tons; Cote Blanche, Louisiana, with annual capacity of 3.4 million tons; and Winsford, Cheshire, United Kingdom, with annual capacity of 1.5 million tons.

Mechanical evaporation

Mechanical evaporation uses high-efficiency vacuum processes to produce high-purity, fine- and coarse-grained salt products for commercial, agricultural, and industrial applications. Compass Minerals is a leading producer of mechanically evaporated salt in North America. It operates mechanical evaporation salt facilities in Lyons, Kansas (annual capacity 450,000 tons), Unity, Saskatchewan (160,000 tons); Goderich, Ontario (130,000 tons); and Amherst, Nova Scotia (130,000 tons). Compass Minerals also operates an SOP evaporation facility at Wynyard, Saskatchewan, with annual capacity of 40,000 tons.

Solar evaporation

Solar evaporation is the oldest and most energy-efficient method of mineral production. At the Great Salt Lake near Ogden, Utah, Compass Minerals draws naturally occurring brine out of the lake into shallow ponds and allows solar evaporation to produce salt, sulfate of potash (SOP) and magnesium chloride. Its SOP plant at the Great Salt Lake is the largest in North America and one of only three SOP brine solar evaporation operations in the world. Annual capacity is 350,000 tons of SOP, 1.5 million tons of salt, and 750,000 tons of magnesium chloride. In 2022 Compass Minerals announced the intention to develop the capacity to extract over 11 kMT LCE (Lithium Carbonate Equivalent) yearly at the Great Salt Lake site. The project has since been put on pause due to regulatory changes.

Business segments

Compass Minerals operates two business segments, Salt and Plant Nutrition.

Read the full text

Compass Minerals’ Salt Segment mines, produces, processes and distributes sodium chloride and magnesium chloride in North America and the U.K. The segment’s largest business is highway deicing, which primarily sells bulk rock salt to states, provinces, counties, municipalities and road maintenance contractors for ice control on public roadways. The highway deicing product line also includes flake and liquid magnesium chloride used for deicing and dust control; treated rock salt treated for deicing in very low temperatures; and rock salt for the chlor-alkali industry.

The salt segment also includes consumer and industrial product lines, which includes pure sodium chloride and blended products containing magnesium chloride, calcium chloride and potassium chloride for applications such as consumer and professional deicing, water conditioning, culinary salt, animal nutrition, swimming pool minerals, and industrial applications.

Compass Minerals’ Plant Nutrition Segment produces sulfate of potash fertilizer.

Compass Minerals’ domestic sales of SOP are concentrated in the Western and Southeastern U.S. and exports to Latin America, Japan, Australia, and New Zealand.

In 2021, Compass Minerals divested the last segment of their plant micronutrient assets in an agreement with Koch Agronomic Services.

Risk factors and legal proceedings

The risks Compass Minerals names in Item 1A of its 10-K filed Dec 12, 2025: 37 risks under these headings, as written.17

  • We are subject to a number of risks that could have a material adverse effect on our business, financial condition, results of operations and the value of our securities. You should carefully consider the following risks and all of the information set forth in this Form 10-K. The risks described below are not the only ones facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our business, financial condition or results of operations.
  • Risks Related to our Restatement and Internal Controls
  • Management identified material weaknesses in the Company’s internal control over financial reporting that resulted in errors in financial statements. If the Company fails to remediate the material weaknesses or experiences additional material weaknesses in the future, it may be unable to accurately and timely report financial results or comply with the requirements of being a public company, which could cause the price of the Company’s common stock to decline and harm its business.
  • Operational Risks
  • Our mining and industrial operations can involve high-risk activities.
  • Geological conditions could lead to a mine shutdown, increased costs, production delays and product quality issues, which could adversely affect results of our operations.
  • The results of our operations are dependent on and vary due to weather conditions and lake level fluctuations. Additionally, adverse weather conditions or significant changes in weather patterns could adversely affect us.
  • Our operations are conducted primarily through a limited number of key production and distribution facilities, and we are also dependent on critical equipment.
  • Our business is capital intensive, and the inability to fund necessary capital expenditures or successfully complete our capital projects could have an adverse effect on our growth and profitability.
  • We face numerous uncertainties in estimating our economically recoverable reserves and resources, and inaccuracies in our estimates could result in lower than expected revenues, higher than expected costs and decreased profitability.
  • Strikes, other forms of work stoppage or slowdown and other union activities could disrupt our business and negatively impact our financial results.
  • Our production processes rely on the consumption of natural gas, electricity, diesel, and certain other raw materials. A significant interruption in the supply or an increase in the price of any of these could adversely affect our business.
The other 27 risks
  • Competition, Sales and Pricing Risks
  • The demand for our products is seasonal.
  • Variables impacting effective inventory management may adversely impact our performance.
  • Anticipated changes in potash prices and customer application rates can have a significant effect on the demand and price for our plant nutrition products.
  • Our products face strong competition and if we fail to successfully attract and retain customers and invest in capital improvements, productivity, quality improvements and product development, sales of our products could be adversely affected.
  • Inflation could result in higher costs and decreased profitability.
  • Increasing costs or a lack of availability of transportation services could have an adverse effect on our ability to deliver products at competitive prices.
  • Risks associated with our international operations and sales and changes in economic and political environments could adversely affect our business and earnings.
  • Conditions in the sectors where we sell products and supply and demand imbalances for competing products can impact the price and demand for our products.
  • Financial Risks
  • Our indebtedness and any inability to pay our indebtedness could adversely affect our business and financial condition.
  • The agreements governing our indebtedness impose restrictions that may limit our ability to operate our business or require accelerated debt payments.
  • We are subject to tax liabilities which could adversely impact our profitability, cash flow and liquidity.
  • If our customers are unable to access credit, they may not be able to purchase our products. In addition, we extend trade credit to customers and the results of our operations may be adversely affected if customers default on these obligations.
  • We are subject to financial assurance requirements and failure to satisfy these requirements could materially affect our business, results of our operations and our financial condition.
  • We ceased paying cash dividends in fiscal 2024; any future cash dividends will be at the discretion of our board of directors and other factors.
  • Legal, Regulatory and Compliance Risks
  • Our operations depend on our rights and governmental authorizations to mine and operate our properties.
  • Unanticipated litigation or investigations, or negative developments in pending litigation or investigations or with respect to other contingencies, could adversely affect us.
  • We are subject to EHS laws and regulations which could become more stringent and adversely affect our business.
  • We could incur significant environmental liabilities with respect to our current, future or former facilities, adjacent or nearby third-party facilities or off-site disposal locations.
  • Compliance with import and export requirements, the FCPA and other applicable anti-corruption laws may increase the cost of doing business.
  • We are subject to costs and risk associated with a complex regulatory, compliance and legal environment, and we may be adversely affected by changes in laws, industry standards and regulatory requirements.
  • We may face significant product liability claims and product recalls, which could harm our business and reputation.
  • Our intellectual property may be misappropriated or subject to claims of infringement.
  • Strategic and Other Business Risks
  • We may not successfully implement our strategies.
  • Our business is dependent upon personnel, including highly skilled personnel. A labor shortage or the loss of key personnel may have a material adverse effect on our performance.
  • If our computer systems, information technology or operations technology are disrupted or compromised, our ability to conduct our business will be adversely impacted.
  • Climate change and related laws and regulations could adversely affect us.
  • We may not be able to expand our business through acquisitions and investments, and acquisitions and investments may not perform as expected. We may not successfully integrate acquired businesses and anticipated benefits may not be realized.

Legal proceedings

We are involved in the legal proceedings described in Part II, Item 8, Note 8. Income Taxes and Part II, Item 8, Note 11. Commitments and Contingencies of our Consolidated Financial Statements and, from time to time, various routine legal proceedings and claims arising from the ordinary course of our business. These primarily involve tax assessments, disputes with former employees and contract labor, commercial claims, product liability claims, personal injury claims and workers’ compensation claims. Management cannot predict the outcome of legal proceedings and claims with certainty. Nevertheless, management believes that the outcome of legal proceedings and claims, which are pending or known to be threatened, even if determined adversely, will not, either individually or in the aggregate, have a material adverse effect on our results of operations, cash flows or financial condition, except as otherwise described in Part II, Item 8, Note 8. Income Taxes, Part II, Item 8, Note 11. Commitments and Contingencies of our Consolidated Financial Statements, and Item 8, Note 18. Subsequent Event.
