**(b) Name of Issuer:**
WK Kellogg Co

**(c) Address of Issuer's Principal Executive Offices:**
One Kellogg Square, P.O. Box 3599, Battle Creek, MI, 49016

**Item 4. Purpose of Transaction**

The Reporting Persons acquired the Common Stock for investment purposes. Gordon previously reported his beneficial ownership of the Common Stock on Schedule 13G.

          On July 10, 2025, the Issuer entered into an Agreement and Plan of Merger (the "Merger Agreement") with Ferrero International S.A., a Luxembourg public limited company ("Acquiror"), and Frosty Merger Sub, Inc., a Delaware corporation and a wholly owned indirect subsidiary of Acquiror ("Merger Sub"), pursuant to which, among other things, upon the terms and subject to the conditions thereof, at the effective time Merger Sub will merge with and into the Issuer, with the Issuer surviving as a wholly owned indirect subsidiary of Acquiror (the "Merger").

          In connection with the Merger Agreement, on July 10, 2025, the Gund Trusts entered into a voting agreement (the "Voting Agreement") with the Acquiror pursuant to which, among other things, each Gund Trust (i) agreed to vote all of its Common Stock (A) in favor of the proposed Merger and (B) against any alternative acquisition proposal, (ii) agreed not to solicit any proxies in connection with any proposal to approve the Merger Agreement, the Merger or any alternative acquisition proposal, (iii) granted an irrevocable proxy to the Acquiror to vote or cause to be voted all of its Common Stock until the termination of the Voting Agreement in the event the Gund Trusts fail to vote their Common Stock in accordance with the Voting Agreement, and (iv) agreed not to sell or transfer its Common Stock except to certain permitted transferees.

          The Voting Agreement will terminate upon the earliest to occur of (i) the termination of the Merger Agreement, (ii) any amendment to the Merger Agreement that adversely affects the consideration payable to stockholders of the Issuer, imposes material restrictions or additional material conditions on consummation of the Merger or extends the latest date on which the Merger Agreement can be consummated before the Merger Agreement terminates, (iii) the mutual written consent of Acquiror and the Gund Trusts or (v) the receipt of majority stockholder approval of the Merger Agreement and Merger.
