Risks

• Ongoing risks to global supply chains, potentially increasing the cost of goods, straining procurement cycles, and impacting customer demand due to tariffs and trade measures.
• Potential for new, substantial tariff increases on imports to the U.S. from Mexico, China, and the European Union (EU) could have a significant adverse effect on the company and its supply chain.
• Exposure to market risk from fluctuating prices of purchased commodity raw materials, including steel, filter media, and petrochemical-based products.
• Challenges in global operations, changes in international trade policy, and impacts of global economic, industrial, and political conditions on product demand.
• Impacts from unexpected events, effects of unavailable raw materials, significant demand fluctuations, or material cost changes.
• Inability to attract and retain qualified personnel, meet customer demand, or maintain competitive advantages.
• Threats from disruptive technologies and effects of highly competitive markets with pricing pressure.
• Exposure to customer concentration in certain cyclical industries.
• Vulnerabilities associated with information technology systems and security.
• Inability to protect and enforce intellectual property rights.
• Costs associated with governmental laws and regulations.
• Impacts of foreign currency fluctuations and effects of changes in capital and credit markets.

Future Outlook

The company expects annual costs related to recently implemented or increased tariffs to be approximately $25 million, down from $35 million previously, and anticipates these costs will be largely offset by pricing increases. Management believes the liquidity available from expected cash generated by operating activities, existing cash, and available credit facilities will be sufficient to meet cash requirements for the next 12 months and beyond, including working capital, debt service, capital expenditures, dividends, share repurchases, and potential acquisitions. The company continues to evaluate the impact of the One Big Beautiful Bill Act (OBBBA) tax provisions, which have staggered effective dates between fiscal years 2025 and 2027, and is evaluating the impact of new FASB ASUs on future disclosures.

Management Comments

• The Company is closely monitoring the evolving trade landscape, as well as its ability to mitigate the impact of tariffs and its analysis of the potential impact.
• The Company will continue to utilize its global manufacturing footprint and supply chain to mitigate the cost impact of tariffs.
• The Company believes the liquidity available from the combination of expected cash generated by operating activities, existing cash and available credit under existing credit facilities will be sufficient to meet its cash requirements for the next 12 months and beyond.
• To determine the level of dividend and share repurchases, the Company considers recent and projected performance across key financial metrics, including earnings, cash flow from operations and total debt.

Industry Context

Donaldson operates in a diverse global filtration market, serving industries from construction and mining to medical devices and microelectronics.
