ENZON PHARMACEUTICALS, INC. 8-K

What Happened

• Enzon Pharmaceuticals, Inc. (ENZN) announced on December 23, 2025 that it entered into a Sixth Amendment to its Section 382 Rights Agreement with Continental Stock Transfer & Trust Company as rights agent.
• The Sixth Amendment changes only the Final Expiration Date for the rights issued under the Rights Agreement, moving it from the close of business on December 31, 2025 to the close of business on January 31, 2026. Management stated the extension is in the best interests of the company and its stockholders.

Key Details

• Amendment filed: Sixth Amendment dated December 23, 2025.
• New Final Expiration Date: January 31, 2026 (previously December 31, 2025).
• Original Rights Agreement dated August 14, 2020; rights agent is Continental Stock Transfer & Trust Company.
• Aside from the Final Expiration Date adjustment, the Rights Agreement remains unmodified.

Why It Matters

• For investors, this filing means the company has extended the period during which the Section 382 rights remain in effect. Management says the extension serves the company's and stockholders' interests.
• The amendment does not change other terms of the Rights Agreement, so existing rights and protections under that agreement continue unchanged until the new expiration date.
