**Item 1. Security and Issuer**

**(a) Title of Class of Securities:**
Common Stock, par value $0.01 per share

**(b) Name of Issuer:**
ENZO BIOCHEM INC

**(c) Address of Issuer's Principal Executive Offices:**
60 EXECUTIVE BLVD, FARMINGDALE, NY, 11735

**Item 4. Purpose of Transaction**

Item 4 is hereby amended to add the following:

On June 23, 2025, the Issuer entered into an Agreement and Plan of Merger (the "Merger Agreement") with Bethpage Parent, Inc., a Delaware corporation ("Parent"), and Bethpage Merger Sub, Inc., a New York corporation and a wholly owned subsidiary of Parent ("Merger Sub"). On August 20, 2025, pursuant to the terms of the Merger Agreement, Merger Sub merged with and into the Issuer (the "Merger") effective as of the effective time of the Merger (the "Effective Time"), with the Issuer continuing as the surviving corporation of the Merger and a wholly owned subsidiary of Parent. At the Effective Time, each Share that was issued and outstanding immediately prior to the Effective Time, subject to certain customary exceptions specified in the Merger Agreement, was automatically converted into the right to receive $0.70 in cash, without interest (the "Merger Consideration")and subject to applicable withholding taxes.

In addition, pursuant to the Merger Agreement, at the Effective Time, (i) each Issuer restricted stock unit ("RSU") that was outstanding as of immediately prior to the Effective Time and was either (A) held by a member of the Issuer's board of directors (whether vested or unvested) or (B) vested in accordance with its terms but not yet settled as of the Effective Time (each, a "Vested RSU") was automatically cancelled and converted into the right to receive an amount in cash, without interest, equal to the product obtained by multiplying (A) the total number of Shares underlying such RSU, by (B) the Merger Consideration, subject to applicable withholding taxes, (ii) each RSU that was outstanding as of immediately prior to the Effective Time and not a Vested RSU was automatically canceled without any consideration payable therefor and (iii) each option to purchase Shares that was outstanding as of immediately prior to the Effective Time was automatically canceled without any consideration payable therefor.

Accordingly, as a result of the Merger, the Reporting Persons no longer beneficially own any securities of the Issuer.

**Item 5. Interest in Securities of the Issuer**

**(a)**
Item 5(a) is hereby amended and restated to read as follows:

Effective August 20, 2025, as a result of the Merger, each Share owned by the Reporting Persons was converted into the Merger Consideration, and each RSU owned by the Reporting Persons was canceled and converted into the right to receive an amount in cash obtained by multiplying (i) the total number of Shares underlying such RSU, by (ii) the Merger Consideration, subject to any withholding of taxes. Accordingly, the Reporting Persons no longer beneficially own any securities of the Issuer.

**(b)**
Item 5(b) is hereby amended and restated to read as follows:

Effective August 20, 2025, as a result of the Merger, each Share owned by the Reporting Persons was converted into the Merger Consideration, and each RSU owned by the Reporting Persons was canceled and converted into the right to receive an amount in cash obtained by multiplying (i) the total number of Shares underlying such RSU, by (ii) the Merger Consideration, subject to any withholding of taxes. Accordingly, the Reporting Persons no longer beneficially own any securities of the Issuer.

**(c)**
Item 5(c) is hereby amended and restated to read as follows:

Except as otherwise set forth in Item 4, there have been no transactions in the securities of the Issuer by the Reporting Persons since the filing of Amendment No. 5 to the Schedule 13D.
