• Milder winter weather patterns due to climate change, leading to reduced demand for de-icing salt, which is a significant portion of Compass Minerals' revenue.
• Increasing environmental scrutiny and potential regulations on road salt usage in various jurisdictions due to concerns about waterway contamination and infrastructure corrosion, which could lead to reduced demand for traditional rock salt or increased costs.

Compass Minerals International (CMP) operates in several key markets, primarily focusing on salt, plant nutrition products, and magnesium chloride. The addressable markets for their main products and services are as follows:

• Salt:
  • The global salt market was valued at approximately USD 25.98 billion in 2024 and is projected to grow to USD 36.12 billion by 2032.
  • The North American salt market reached USD 5.78 billion in 2024 and is projected to grow to approximately USD 9.51 billion by 2034.
• Plant Nutrition:
  • The global plant nutrition market size was USD 12.63 billion in 2024 and is projected to reach USD 19.89 billion by 2033.
  • North America accounted for approximately 24% of the global plant nutrition market share in 2024.
  • The broader North America fertilizer market, which includes plant nutrition, is expected to reach US$ 92.23 billion by 2033 from US$ 68.68 billion in 2024.
• Magnesium Chloride:
  • The global magnesium chloride market is projected to grow from USD 737.9 million in 2025 to USD 1,225.1 million by 2035.
  • North America holds the second-largest share of the global magnesium chloride market. In 2019, the North America market volume for magnesium chloride surged to 403.6 Kilo Tonnes. The U.S. region alone is projected to achieve a market value of $132.84 million by 2030.

Compass Minerals International (CMP) is expected to drive future revenue growth over the next 2-3 years through several key initiatives and market dynamics:

1. Growth in the Plant Nutrition Segment: The Plant Nutrition business has demonstrated strong performance, with revenue increasing by 15% year-over-year in Q3 2025 due to improved sales volumes and enhanced production efficiency. This segment also saw a 16% year-over-year revenue increase in Q2 2025, driven by robust sales volumes.
2. Improved Pricing and Volumes in the Salt Business: The company is anticipating favorable conditions in its Salt business, particularly in highway deicing. In Q3 2025, Compass Minerals realized a 1% increase in average highway deicing selling prices and a 5% increase in sales volumes year-over-year. Management has indicated that the North American bid season is progressing well, with improvements in both pricing and commitment sizes compared to the previous year.
3. Operational Efficiency and "Back-to-Basics" Strategy: Compass Minerals is focusing on an optimization-driven "back-to-basics" strategy aimed at enhancing efficiency and profitability. This strategy has already led to declining costs in the salt business, contributing to adjusted EBITDA margin expansion and per-ton growth. Improved operational efficiency can enable more competitive pricing and better market penetration, thereby boosting revenue.
4. Strategic Inventory Management and Working Capital Optimization: While not a direct revenue driver, the company's efforts in managing inventory levels are expected to positively impact its financial flexibility and ultimately support revenue growth. Significant progress was made in Q2 2025 by reducing North American highway deicing inventory values and volumes by 47% and 59%, respectively, year-over-year. This resulted in approximately $145 million in working capital release and a reduction in total debt by over $170 million, freeing up capital for potential reinvestment in growth initiatives. Furthermore, adjusted EBITDA per ton is projected to improve as highway deicing salt produced at normalized levels is sold in future periods, contributing to overall profitability that can fund growth.

Outbound Investments

• Compass Minerals acquired the remaining 55% of Fortress, its fire retardant business, prior to fiscal year 2024.
• In late March 2025, the company announced it was winding down its fire retardant business (Fortress) to focus on its core Salt and Plant Nutrition segments.
• For the nine months ended June 30, 2025, the company sold certain assets and intellectual property related to Fortress for net proceeds of $19.6 million.

Capital Expenditures

• Total capital expenditures for fiscal year 2024 were $114.2 million, which included approximately $20.2 million related to the now-terminated lithium project.
• For fiscal year 2025, capital expenditures are projected to be in the range of $75 million to $85 million. This guidance was subsequently reduced by approximately $45 million in late 2025.
• A primary focus of capital allocation has been on improving cash flow generation and returns on capital in the core Salt and Plant Nutrition businesses, alongside the termination of the lithium development project.
