Welcome to our dedicated page for Enzo Biochem SEC filings (Ticker: ENZ), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
The Enzo Biochem, Inc. (ENZ / ENZB) SEC filings record provides detailed insight into the company’s evolution as a life sciences tools provider and its eventual transition to private ownership. As an SEC registrant, Enzo filed periodic reports and numerous current reports on Form 8-K that document financial performance, strategic shifts, listing status changes, and corporate transactions.
For investors and researchers, Form 8-K filings are central to understanding key events. In 2024 and 2025, Enzo used 8-Ks to report matters such as NYSE notices of non-compliance, the decision to voluntarily delist from the NYSE and move trading to OTCQX, and the later disclosure that its common stock began trading on OTCQX under the symbol ENZB. A June 24, 2025 Form 8-K describes the Agreement and Plan of Merger with Bethpage Parent, Inc. and Bethpage Merger Sub, Inc., including the proposed cash consideration per share and conditions to closing.
An August 19, 2025 Form 8-K records the shareholder vote at a special meeting where the merger proposal was approved. A subsequent August 20, 2025 Form 8-K reports the completion of the merger, stating that Bethpage Merger Sub, Inc. merged with and into Enzo Biochem, Inc., with Enzo surviving as a wholly owned subsidiary of Bethpage Parent, Inc. That filing explains that each share of common stock was converted into the right to receive cash consideration and that the shares ceased trading on OTCQX and other over-the-counter markets.
On the same date, Enzo filed Form 15 (Form 15-12G), certifying the termination of registration of its common stock under Section 12(g) of the Exchange Act and the suspension of its reporting obligations under Sections 13 and 15(d). The Form 15 identifies the common stock, par value $0.01 per share, as the class of securities covered and notes reliance on Rule 12g-4(a)(1) and Rule 12h-3(b)(1)(i). Together, these filings mark Enzo’s transition from a publicly traded, SEC-reporting issuer to a wholly owned private subsidiary.
