Item 1.01 Entry into a Material Definitive Agreement. On October 22, 2026, Winnebago Industries, Inc. (the “Company”) entered into a cooperation agreement (the “Cooperation Agreement”) by and between the Company and Vision One Fund, LP, Vision One Management Partners, LP, Vision One Fund Partners, LP, Vision One Management Partners Holdings, LP, Vision One Management Partners GP, LLC, Vision One Onshore Fund, LP and Vision One Offshore Fund, LP (collectively with their affiliates, “Vision One”). Pursuant to the Cooperation Agreement, the Company has agreed to (i) take all necessary actions to nominate Jay L. Johnson (the “New Director”) for election to the Board of Directors of the Company (the “Board”) as an independent Class III director at the Company’s 2026 annual meeting of shareholders (the “2026 Annual Meeting”) for a term expiring at the Company’s 2029 annual meeting of shareholders (the “2029 Annual Meeting”); (ii) include the New Director in the Board’s slate of director nominees for election at the 2026 Annual Meeting, recommend his election to the Company’s shareholders and solicit proxies in favor of his election; and (iii) following his election to the Board, take all necessary actions to appoint the New Director to the Board’s Audit and Finance Committee and maintain his membership on such committee until the termination of the Cooperation Agreement, subject to certain conditions. From the conclusion of the 2026 Annual Meeting until the termination of the Cooperation Agreement, the size of the Board will not exceed ten (10) directors. In addition, pursuant to the Cooperation Agreement, the Board has agreed to take all necessary actions to rename the Audit Committee to the “Audit and Finance Committee” and amend the committee’s charter to provide for additional clarity regarding the committee’s oversight of the Company’s capital structure, investments, uses of cash and capital allocation. Until the termination of the Cooperation Agreement, and as long as Vision One continues to beneficially own at least the lesser of (i) 0.9% of the then-outstanding shares of the Company’s common stock and (ii) 250,000 shares of the Company’s common stock, in the event that the New Director is unable or unwilling to stand for election at the 2026 Annual Meeting or to serve as a director for any reason or ceases to serve as a director of the Company, Vision One will be entitled to propose potential replacement directors mutually agreeable to the Company and Vision One, subject to certain qualifications and other conditions, until Vision One and the Company mutually agree on a replacement director. Pursuant to the Cooperation Agreement, the Company has agreed to submit for shareholder approval at the 2026 Annual Meeting amendments to its Articles of Incorporation and conforming amendments to its Amended and Restated Bylaws to phase out the classified Board over a three-year period. The Board will recommend that shareholders vote in favor of, and the Company will solicit proxies and use reasonable best efforts to obtain approval of, such amendments, including by using reasonable best efforts to have all directors and officers of the Company vote in favor of such proposals and by engaging a nationally recognized proxy solicitor. Subject to shareholder approval and effectiveness of such amendments, directors elected at the Company’s 2027 annual meeting of shareholders and at each subsequent annual meeting of shareholders will be elected for one-year terms as their respective terms expire, with all directors standing for annual election beginning at the 2029 Annual Meeting. Pursuant to the Cooperation Agreement, Vision One has irrevocably withdrawn its notice of shareholder proposals and director nominations, dated September 15, 2026, and has agreed to cease all solicitation activities in respect of the 2026 Annual Meeting. The Cooperation Agreement also contains customary voting commitments, standstill, non-disparagement and other provisions. The Cooperation Agreement will terminate on the earlier of (i) the date that is thirty (30) calendar days prior to the deadline under the Company’s Amended and Restated Bylaws for the submission of shareholder nominations of director candidates for election to the Board at the Company’s 2027 annual meeting of shareholders and (ii) the date that is one hundred twenty (120) calendar days prior to the one-year anniversary of the 2026 Annual Meeting, unless earlier terminated in accordance with its terms. The foregoing description of the Cooperation Agreement is qualified in its entirety by reference to the full text of the Cooperation Agreement, a copy of which is attached hereto as Exhibit 10.1 and incorporated herein by reference.
