Nuveen Municipal Value Fund, Inc. filed a Current Report on Form 8-K with the U.S. Securities and Exchange Commission on October 8, 2026, announcing a change to its investment policies. The filing indicates that the Fund’s Board of Trustees has adopted a new policy requiring the investment of at least 80% of the Fund's assets in municipal bonds. Specifically, these bonds must be selected to enhance portfolio value by delivering income to the Fund.

The policy is set to become effective as of October 30, 2026. The filing details the procedural requirements for changing this specific policy. Under the Investment Company Act of 1940, the policy to invest at least 80% of assets in income-generating municipal bonds cannot be changed without 60 days of prior written notice to shareholders. Additionally, the policy to invest at least 80% of assets in tax-exempt municipal securities requires approval from a majority of outstanding common stock and preferred shares voting together as a single class, as well as approval from a majority of outstanding preferred shares voting separately.

The filing also notes that the Board of Trustees retains the authority to change the policies described in the report without requiring a shareholder vote.
