ENZ Merger Closed — Shareholders Cashed Out at $0.70 Per Share

Rhea-AI Filing Summary

Enzo Biochem, Inc. (ENZ) entered into and completed a merger in which Bethpage Merger Sub merged into Enzo, and Enzo became a wholly owned subsidiary of Bethpage Parent.

At the effective time on August 20, 2025, each outstanding share was converted into the right to receive $0.70 in cash per share (subject to withholding). Vested restricted stock units held by directors or vested-but-unsettled RSUs were converted into a cash payment equal to the number of underlying shares multiplied by $0.70. Unvested RSUs and all outstanding options were canceled without consideration. As a result, the reporting persons state they no longer beneficially own any Enzo securities and ceased to own more than 5% of the class.

Positive

• Merger completed making Enzo a wholly owned subsidiary of Bethpage Parent
• $0.70 per share in cash provided to holders of outstanding shares
• Vested RSUs received cash equal to underlying shares multiplied by the merger consideration

Negative

• Unvested RSUs were canceled without consideration
• All outstanding options were canceled without any consideration
• Reporting persons ceased to own more than 5% of the class, eliminating their public ownership stake

Insights

M&A Specialist

TL;DR: The merger closed for cash consideration of $0.70 per share; equity awards were largely cashed out or cancelled.

The filing confirms a cash-out transaction where each public share converted into $0.70 and vested RSUs received equivalent cash; unvested RSUs and options were cancelled without payout. This structure is typical for a take-private cash merger that eliminates public float and converts equity awards at closing. Material implication: public shareholders received immediate cash consideration while outstanding derivative awards were extinguished per agreement terms.

Corporate Governance Expert

TL;DR: Reporting persons no longer hold ENZ securities post-merger; governance rights and public shareholder oversight end.

The amendment restates Items 4 and 5 to reflect the merger mechanics and the conversion/cancellation of equity awards. It explicitly notes that reporting persons ceased to beneficially own more than 5% as of August 20, 2025. From a governance perspective, the company transitioned to private ownership and board and incentive structures were resolved through cash settlements for vested awards and cancellation of unvested awards and options.
