ABRDN NATIONAL MUNICIPAL INCOME FUND (VFL) ANNOUNCES PROPOSED REORGANIZATION AND SPECIAL SHAREHOLDER MEETING

• Appoint the US Subsidiary of Aberdeen Investments, abrdn Inc., to serve as the investment adviser to the Surviving Fund;
• Appoint the incumbent VFL trustees plus one additional independent trustee to serve as the Surviving Fund's board of trustees; and
• Approve the issuance of shares in connection with the reorganization.

Upon closing, it is intended that the Surviving Fund's name will change from "MFS Municipal Income Trust" to "Aberdeen Municipal Income Fund."

The goal of this reorganization is to create a larger, more efficient fund with greater economic scale and increased trading volume, which may help reduce the discount to net asset value over time. For VFL shareholders, the transaction offers the opportunity to continue their investment in a significantly larger fund with the potential for a higher annual distribution rate, targeted at 6% of the Surviving Fund's net asset value.

The proposal is subject to certain conditions, including shareholder approval. VFL's common and preferred shareholders of record as of December 11, 2025 will be asked to vote on the proposal at a special meeting, tentatively scheduled for March 11, 2026. If approved and all other conditions are met, the reorganization is expected to close in the second quarter of 2026.

Detailed information will be provided in a proxy statement/prospectus to be sent to VFL's shareholders. A registration statement containing a proxy statement/prospectus has yet to be filed with the U.S. Securities and Exchange Commission (the "SEC"). After the registration statement is filed with the SEC, it may be amended or withdrawn. A proxy statement/prospectus will not be distributed to shareholders of VFL unless and until a registration statement containing the proxy statement/prospectus is declared effective by the SEC.

The information in this press release is for informational purposes only and shall not constitute an offer to sell or the solicitation of an offer to sell or the solicitation of an offer to buy any securities or the solicitation of any vote or approval in any jurisdiction pursuant to or in connection with the proposed transaction or otherwise, nor shall there be any sale, issuance or transfer of securities in any jurisdiction in contravention of applicable law.

In connection with the proposed combination, the Surviving Fund plans to file with the SEC a combined prospectus/proxy statement.

The prospectus/proxy statement, when available, will be available for free at the SEC's website www.sec.gov.

Closed-end funds are traded on the secondary market through one of the stock exchanges. A Fund's investment return and principal value will fluctuate so that an investor's shares may be worth more or less than the original cost. Shares of closed-end funds may trade above (a premium) or below (a discount) the net asset value (NAV) of the fund's portfolio. There is no assurance that a Fund will achieve its investment objective. Past performance does not guarantee future results.

The value at which a closed-end fund stock trades on a stock exchange is a function of external market factors that are not under the control of the Fund's Board or Investment Advisor. Closed-end Fund shares may therefore trade at a premium or a discount to net asset value at any given time. Shareholders should be aware that a fund trading at a premium to net asset value may not be sustainable, and a fund's discount to net asset value can widen as well as narrow. Shareholders of a fund trading at a premium who participate in that fund's dividend reinvestment plan should note the reinvestment of distributions may occur at a premium to net asset value.
