WINNEBAGO INDUSTRIES INC

During the three months ended August 30, 2025, no director or officer of the Company adopted, modified orterminated 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.

On October 20, 2025, the Human Resources Committee of the Board of Directors approved the Winnebago Motorhome Profitability Improvement Bonus Plan for key members of the Company’s Winnebago Motorhome leadership team, including Casey J. Tubman, Group President – Newmar and Winnebago Motorized. The plan is designed to promote the growth and profitability of the Company’s Winnebago Motorhome business. The plan provides an opportunity for the participant to earn some or all of a certain bonus amount ($0.9 million in the case of Mr. Tubman), with one-third of the amount earned upon achievement of each of three operating margin improvement goals for the Company’s Winnebago Motorhome business, each to be achieved over a trailing twelve-month period, by the end of Fiscal 2028. Amounts earned under the plan will be paid one-half in cash and one-half in restricted stock units that vest after one year. The restricted stock units will have terms consistent with the Company’s customary form of restricted stock unit award, provided that the restricted stock units will also vest in the event the participant’s employment is involuntarily terminated without cause.
