The following constitutes Amendment No. 4 to the Schedule 13D filed by the undersigned (“Amendment No. 4”). This Amendment No. 4 amends the Schedule 13D as specifically set forth herein.

Item 3.

Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated in its entirety to read as follows:

The Shares purchased by the Radoff Foundation were purchased with working capital (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business). The aggregate purchase price of the 430,000 Shares directly owned by the Radoff Foundation is approximately $1,427,845, including brokerage commissions.

4,155,600 of the Shares directly owned by Mr. Radoff were purchased with personal funds (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business). The aggregate purchase price of such Shares purchased by Mr. Radoff is approximately $13,026,662, including brokerage commissions. In his capacity as a director of the Issuer, Mr. Radoff has also been awarded 155,917 restricted stock units (“RSUs”), 19,532 of which have vested as of the date hereof. The remainder of Mr. Radoff’s RSUs vest as described in Item 6 hereof.

Item 4.

Purpose of Transaction.

Item 4 is hereby amended to add the following:

On March 16, 2023, the Issuer and Enzo Clinical Labs, Inc., a New York corporation (together with the Issuer, the “Seller”), entered into an Asset Purchase Agreement (the “Purchase Agreement”) with Laboratory Corporation of America Holdings (“Labcorp”). Pursuant to the Purchase Agreement, the Seller has agreed to sell certain assets and assign certain liabilities of its clinical labs business to Labcorp in exchange for approximately $146,000,000 in cash (subject to certain adjustments), on and subject to the terms and conditions set forth therein (such transaction, the “Transaction”). The closing under the Purchase Agreement is contingent on the Issuer obtaining approval of the Transaction by stockholders of the Issuer holding a majority of the Shares outstanding.

In connection with the Purchase Agreement, on March 16, 2023, Mr. Radoff, among other stockholders of the Issuer, entered into separate voting agreements (each, a “Voting Agreement”) with Labcorp. Under the terms of the Voting Agreement, Mr. Radoff has agreed, among other things, to vote all of the Shares that he beneficially owns: (i) in favor of adoption and approval of the Purchase Agreement and the Transaction; (ii) against any Alternative Transaction (as defined in the Purchase Agreement); and (iii) against any other action that is intended or could reasonably be expected to impede or interfere with or materially delay the Transaction or any other transactions contemplated by the Purchase Agreement. In addition, pursuant to the Voting Agreement, Mr. Radoff granted an irrevocable proxy to Labcorp to vote the Shares beneficially owned by him in accordance with the foregoing.

The Voting Agreement and the irrevocable proxy granted to Labcorp thereunder will automatically terminate upon the occurrence of certain circumstances, including the termination of the Purchase Agreement in accordance with its terms or the closing of the Transaction.

The foregoing description of the Voting Agreement does not purport to be complete and is qualified in its entirety by reference to the form of Voting Agreement, which is attached as Exhibit 99.1 hereto and is incorporated herein by reference.
