On July 7, 2022, the Company entered into an Agreement and Plan of Merger (as it may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”) with SD Biosensor, Inc., a corporation with limited liability organized under the laws of the Republic of Korea (“SDB”), Columbus Holding Company, a Delaware corporation (“Parent”), and Madeira Acquisition Corp., an Ohio corporation and a direct wholly owned subsidiary of Parent (“Merger Sub”). Meridian is informed that SJL Partners, LLC (“SJL”) is currently the sole shareholder of Parent, and SDB together with SJL will be the sole shareholders of Parent as of the closing of the Merger. Pursuant to the Merger Agreement, Merger Sub will merge with and into Meridian (the “Merger”), with Meridian surviving the Merger as a direct wholly owned subsidiary of Parent.

At the effective time of the proposed Merger (the “Effective Time”), each share of common stock, no par value per share, of the Company issued and outstanding as of immediately prior to the Effective Time (other than dissenting shares or shares of the Company’s common stock held by the Company as treasury stock or owned by SDB, Merger Sub or any subsidiary of the Company or SDB) will be cancelled and cease to exist and automatically convert into the right to receive cash in an amount equal to $34.00, without interest.

Consummation of the Merger is subject to customary closing conditions, including, without limitation: (i) the absence of certain legal impediments; and (ii) the condition that no Specified Outcome, as such term is defined in the Merger Agreement, related to the DOJ LeadCare legal matter (which is described in the section entitled “Legal Matter Relating to LeadCare Product Line” of Item 3. “Legal Proceedings”) has occurred or is reasonably likely to occur.

On November 21, 2022, the parties received clearance from the Committee on Foreign Investment in the United States with respect to the Merger and the transactions contemplated by the Merger Agreement.

The Merger Agreement contains certain termination rights for the Company and SDB. In addition to the foregoing termination right, and subject to certain limitations: (i) the Company or SDB may terminate the Merger Agreement if the Merger is not consummated by January 6, 2023; and (ii) the Company and SDB may mutually agree to terminate the Merger Agreement.

The Company incurred transaction related costs of approximately $6,800 during the year ended September 30, 2022 related to the Merger, which is recorded in acquisition and transaction related costs in the Consolidated

Statements of Operations.
