Compass Minerals is a mining and minerals company with two businesses: salt and sulfate of potash (SOP) fertilizer. Salt dominates, at roughly 82% of revenue, and is used primarily for highway deicing — states, municipalities, and road contractors buy bulk salt to keep roads safe in winter. Salt is also sold for water conditioning, food processing, and industrial uses. Compass operates major rock salt mines in Goderich, Ontario (the world's largest underground rock salt mine) and Winsford, UK, plus solar evaporation facilities in Ogden, Utah. An extensive depot network along the Great Lakes and major river systems supports delivery. Salt pricing is set largely through annual competitive government bid processes. The remaining ~18% of revenue comes from Plant Nutrition, which produces SOP — a specialty potassium fertilizer sold under the Protassium+ brand — at its Ogden, Utah facility, the largest SOP operation in the Western Hemisphere. SOP targets high-value, chloride-sensitive crops like fruits and nuts. Compass's near-term strategy is operational: restoring salt production to normalized levels after deliberate curtailment in FY24–FY25 (to improve fixed-cost absorption), and executing a multi-year restoration of its SOP solar evaporation ponds to lower production costs. Capital allocation is focused on debt reduction, with no dividend planned.
