On March 14, 2025, Neil. D. Brinker, President and Chief Executive Officer of the Company, terminated his Rule 10b5-1 trading plan that had been adopted on December 20, 2024, and was previously scheduled to expire on December 31, 2025. Subsequently, on March 24, 2025, Mr. Brinker adopted a Stock Sale Plan (the “Plan”) intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act. The Plan provides for the sale of 3,400 vested restricted stock units, plus 100% of the shares resulting from the vesting of certain currently unvested restricted stock units during the sales period, net of shares surrendered to the Company or sold to cover withholding taxes. The Plan provides for the sale of shares of Modine common stock subject to a specified formula and other terms and conditions, beginning on July 1, 2025 and ending on March 31, 2026.

During the three months ended March 31, 2025, no other director or officer of the Company adopted or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.
