Enzon Pharmaceuticals Announces Extension of Exchange Offer and Material Modifications for Shareholders

Cranford, NJ, March 11, 2026 – Enzon Pharmaceuticals, Inc. (OTC: ENZN), a company specializing in biological products, has released a Form 8-K filing announcing several key developments that are highly relevant to its shareholders and could impact the company’s valuation.

Key Highlights from the 8-K Filing

• Extension of Exchange Offer: Enzon has announced the extension of its exchange offer for holders of its Series C Non-Convertible Redeemable Preferred Stock. The offer, which allows Series C Preferred Stockholders to exchange their shares for Enzon common stock, will now expire at 5:00 p.m. Eastern Time on March 16, 2026, unless further extended. This extension provides shareholders more time to evaluate and participate in the offer.
• Potential Value Impact: The exchange offer is a critical event, as it could impact the company’s capital structure and future dilution of common shares. Investors should closely monitor participation rates and potential shifts in ownership dynamics.
• Material Modifications to Security Holders’ Rights: Enzon’s Board of Directors has approved the Ninth Amendment to its Rights Agreement, further extending the “Final Expiration Date” for shareholder rights to noon, New York City Time, on March 18, 2026. This amendment replaces all prior references to the previous expiration date in the relevant exhibits and agreements.
• Merger Developments: The company is actively engaged in proposed transactions with Viskase Companies, Inc. In connection with this, Enzon has filed a registration statement on Form S-4 with the SEC, which includes documentation for a prospectus, consent solicitation statement, and offer to exchange. The Registration Statement contains financial information about the combined company. This potential merger could significantly reshape Enzon’s business profile, financials, and shareholder value.
• Regulatory Disclosures: The company has emphasized that certain information, including press releases and exhibits related to these events, is not considered “filed” for certain Exchange Act purposes and thus is not automatically incorporated by reference into other filings unless explicitly stated.
• Forward-Looking Statements and Risks: Enzon cautions that forward-looking statements regarding the merger and related transactions are subject to risks, including the possibility that the merger conditions may not be satisfied, the timing of the closing, the ability of Viskase to provide required financial statements, and whether anticipated benefits will be realized. These uncertainties mean the share price may be volatile as the situation develops.

What Should Shareholders Know?

• Exchange Offer Participation: Shareholders holding Series C Preferred Stock should carefully review the terms and consider whether to exchange their shares for common stock before the new deadline.
• Rights Agreement Amendment: The extension of the Rights Agreement’s expiration date is designed to protect shareholder interests and may act as a defensive measure in the context of ongoing strategic transactions, including the proposed merger.
• Merger Status: The potential combination with Viskase may materially impact Enzon’s operations, strategic direction, and market valuation. Shareholders are encouraged to review all materials filed with the SEC, particularly the S-4 Registration Statement, for detailed financial and strategic implications.
• Trading Status: The company currently does not have any securities registered under Section 12(b) and is not listed on a national securities exchange. Investors should be aware of the liquidity risks associated with OTC securities.
