Aberdeen Municipal Income Fund (MFM) Announces 25% Increase in Monthly Distribution and Adoption of Stable Distribution Policy

PHILADELPHIA, June 9, 2026 /PRNewswire/ -- The Board of Trustees of Aberdeen Municipal Income Fund (NYSE: MFM) ("MFM") has adopted a stable distribution policy ("SDP") for the Fund at an annualized rate equal to 6.00% of MFM's net asset value, as discussed in MFM's Proxy dated January 30, 2026.

The implementation of the SDP results in a meaningful enhancement to the shareholder distribution rate, with the Fund's monthly distribution increased from $0.0240 per share to $0.0300 per share, representing a 25% increase over the prior distribution level. This higher payout reflects the Fund's commitment to delivering consistent, competitive cash flow to shareholders.

The new distribution will be paid on June 30, 2026, to shareholders of record as of June 23, 2026 (ex-dividend date June 23, 2026). The increased distribution rate reflects both the Fund's income-generating capability and the Board's focus on maximizing the return of income to shareholders in a stable and predictable manner.

Distributions under the SDP are expected to be derived primarily from current income and may be supplemented by net realized capital gains, if any, and, to the extent necessary, a return of paid-in capital.

Important Information

Shares of closed-end funds are listed for trading on national securities exchanges and are bought and sold in the secondary market. The market price of a fund's shares is determined by supply and demand and may be greater than (a "premium") or less than (a "discount") the fund's net asset value (NAV). A fund's investment return and principal value will fluctuate, and investors may receive more or less than their original investment upon the sale of shares. There is no assurance that a fund will achieve its investment objective. Past performance is not indicative of future results.

The trading price of a closed-end fund's shares may be influenced by various factors, including market conditions, investor sentiment, and other external forces, and is not directly controlled by the fund, its Board of Directors, or its investment adviser. As a result, shares may trade at a premium to or discount from NAV at any given time. A premium to NAV may not be sustained, and a discount to NAV may increase or decrease over time. Investors should consider these risks when purchasing or selling closed-end fund shares.

Shareholders whose fund shares trade at a premium to NAV and who participate in the fund's dividend reinvestment plan should be aware that distributions may be reinvested at prices above NAV, which may adversely affect investment results.

The Fund's policy is expected to provide a steady and sustainable cash distribution to Fund shareholders that may help reduce the Fund's current discount to NAV. There is no assurance that a Fund will achieve these results. Shareholders should not draw any conclusions about the Fund's investment performance from the amount of the distributions or the terms of the Fund's policy.

At the end of each calendar year, a Form 1099-DIV will be sent to shareholders, which will state the amount and composition of the fund's distributions and provide information with respect to their appropriate tax treatment for the prior calendar year. You should not draw any conclusions about any of these Funds' investment performance from the amount of the distributions.

Circular 230 disclosure: To ensure compliance with requirements imposed by the U.S. Treasury, we inform you that any U.S. tax advice contained in this communication (including any attachments) is not intended or written to be used, and cannot be used, for the purpose of (i) avoiding penalties under the Internal Revenue Code or (ii) promoting, marketing or recommending to another party any transaction or matter addressed herein.
