(formerly known as Landec Corporation) (the "Issuer"). Except as specifically amended hereby, the disclosures set forth in the Schedule 13D, as previously amended, remain unchanged.

Purpose of transaction

Item 4 is hereby amended to add the following: On September 27, 2026, the Wynnefield Reporting Persons entered into a Voting and Support Agreement (the "Support Agreement") with Lifecore, Inc., a Delaware corporation ("Parent"), and the Issuer in connection with the Agreement and Plan of Merger, dated as of September 27, 2026, among Parent, Hazel Merger Sub, Inc., a Delaware corporation and direct wholly owned subsidiary of Parent ("Merger Sub"), and the Issuer (the "Merger Agreement"). The Merger Agreement provides, among other things and subject to its terms and conditions, for the merger of Merger Sub with and into the Issuer, with the Issuer surviving the merger. Pursuant to the Support Agreement, and subject to its terms and conditions, the Wynnefield Reporting Persons agreed to vote their Covered Shares (as defined in the Support Agreement) in favor of the adoption and approval of the Merger Agreement, the merger and the other transactions contemplated by the Merger Agreement, and in favor of certain proposals to adjourn or postpone a meeting of the Issuer's stockholders if necessary to establish a quorum or obtain the required stockholder vote. The Wynnefield Reporting Persons also agreed to vote their Covered Shares against certain competing acquisition proposals and other matters that would reasonably be expected to impede, interfere with or materially and adversely affect the consummation of the merger, and to cause their Covered Shares to be present for purposes of establishing a quorum. The Support Agreement also contains restrictions on transfers of Covered Shares, subject to specified permitted transfers generally conditioned upon the transferee agreeing to be bound by the Support Agreement. Covered Shares include certain after-acquired shares, including shares of Common Stock acquired upon conversion of Series A Preferred Stock. The Wynnefield Reporting Persons also waived appraisal rights with respect to their Covered Shares and agreed to certain customary limitations on actions challenging or delaying the transactions, in each case subject to the terms and exceptions set forth in the Support Agreement. The Support Agreement generally terminates upon the earliest to occur of the time the required stockholder vote is obtained, the effective time of the merger, the termination of the Merger Agreement or a change in the recommendation of the Issuer's board of directors effected in accordance with the Merger Agreement; provided that, if termination occurs because the required stockholder vote is obtained, the voting obligations in Section 3 survive until the earlier events specified in the Support Agreement. In addition, each Wynnefield Reporting Person may terminate the Support Agreement as to itself following certain adverse changes to the contingent value rights or other consideration payable to it. Certain provisions survive termination. Each Wynnefield Reporting Person entered into the Support Agreement solely in its capacity as a stockholder, and the Support Agreement does not limit actions taken in a director, officer or employee capacity in accordance with the fiduciary-duty provisions set forth therein. In addition, on June 30, 2026, Wynnefield Partners Small Cap Value, L.P. I, Wynnefield Partners Small Cap Value, L.P. and Wynnefield Small Cap Value Offshore Fund, Ltd. delivered to the Issuer notices of redemption with respect to all of the shares of Series A Preferred Stock held by them. Pursuant to the Certificate of Designations governing the Series A Preferred Stock, the applicable redemption amounts are payable on December 28, 2026. The foregoing description of the Support Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Support Agreement, a copy of which is filed as Exhibit 99.1 to this Amendment No. 11 and incorporated herein by reference.
