Legal Proceedings: The company is involved in various claims and legal actions in the ordinary course of business, including product liability claims, employee claims, workers’ compensation claims, and class action lawsuits. While liability insurance is maintained, coverage may not be adequate or available in the future. The company believes the outcome of current proceedings will not have a material adverse effect on its financial condition, results of operations, or cash flows.

Tax Strategy & Considerations

Tax Profile:

• Effective Tax Rate: The effective income tax rate was 21.1% for fiscal year 2025, compared to 22.6% for fiscal year 2024.
• Geographic Tax Planning: The company's domestic and international tax liabilities are influenced by the geographic distribution of earnings. As of September 30, 2025, approximately $30 million of undistributed foreign subsidiary earnings are intended for indefinite reinvestment, with no income tax provision made for these amounts.
• Tax Reform Impact: The One Big Beautiful Bill Act (H.R. 1), signed into law on July 4, 2025, contains tax reform provisions, with the majority impacting the company starting in fiscal year 2027. The impact on fiscal year 2025 operating results was not material. Many jurisdictions where the company operates (e.g., Canada, U.K., Germany) have adopted the OECD Pillar Two Rules, with varying effective dates between fiscal 2025 and fiscal 2026.

Insurance & Risk Transfer

Risk Management Framework:
