[8-K] abrdn National Municipal Income Fund Reports Material Event
Rhea-AI Filing Summary
abrdn National Municipal Income Fund is significantly expanding its ability to invest in riskier municipal bonds. Effective June 1, 2026, the fund’s non-fundamental policy will change from allowing up to 20% of net assets in below-investment-grade municipal obligations to permitting up to 100% of assets in such securities.
The Board expects to raise actual high-yield exposure in stages, initially to about 30% of the portfolio and then to roughly 30%–50% over time, depending on market conditions. This shift raises credit and volatility risk but is intended to broaden diversification and may support greater earnings, distributions, and long-term risk-adjusted returns for shareholders.

Negative

Insights
VFL is increasing its capacity to use high-yield munis, trading more income potential for higher credit risk.
abrdn National Municipal Income Fund is removing its prior cap that limited below-investment-grade municipal holdings to 20% of net assets. The policy will allow up to 100% of assets in high-yield or unrated municipals judged comparable by the manager starting on June 1, 2026.
The Board expects exposure to move to about 30% initially and then to roughly 30%–50% over time, so the portfolio will not immediately become all high-yield. The fund highlights that high-yield municipal bonds are speculative, more volatile, and less liquid, increasing loss and pricing risk.
The Board considered these higher risks against possible benefits like expanded diversification, greater earnings, higher distributions, and improved long-term risk-adjusted returns, and concluded a broader mandate better serves shareholders. Actual impact will depend on how quickly exposure scales within the stated ranges and on market conditions for high-yield municipals.

| Item 8.01. | Other Events |
On April 15, 2026, the Board of Trustees (the “Board”) of abrdn National Municipal Income Fund (the “Fund”) approved a change in the Fund’s non-fundamental investment policy relating to investments in below-investment grade municipal obligations as set forth below. This change will be effective on June 1, 2026.
| Current | New |
| “The Fund may invest up to 20% of its net assets in Municipal Obligations that are rated below investment grade or that are unrated but judged by the Investment Manager to be of comparable quality.” | “The Fund may invest up to 100% of its assets in Municipal Obligations that are rated below investment grade or that are unrated but judged by the Investment Manager to be of comparable quality.” |
All other investment limitations remain unchanged.
Exposure to Below Investment Grade Quality Municipal Obligations
Removing this non-fundamental investment limitation may result in larger credit exposure and greater investment risk from below investment grade quality Municipal Obligations. In particular, the Fund’s anticipated larger allocation (initially 30% and between approximately 30% and 50% over time) to below investment grade quality Municipal Obligations increases the risk from investment in high-yield bonds. The risk for investments in high-yield bonds and other lower-rated securities is as follows: Investments in high-yield bonds (commonly referred to as “junk bonds”) and other lower-rated securities will subject the Fund to substantial risk of loss. Investments in high-yield bonds are speculative and issuers of these securities are generally considered to be less financially secure and less able to repay interest and principal than issuers of investment-grade securities. Prices of high-yield bonds tend to be very volatile. These securities are less liquid than investment-grade debt securities and may be difficult to price or sell, particularly in times of negative sentiment toward high-yield securities.
A copy of the press release relating to the changes described above is attached hereto as Exhibit 99.1.

Exhibit 99.1
abrdn National Municipal Income Fund (VFL) Announces Removal of Non-Fundamental Investment Policy Restricting Investments in High-Yield Municipal Securities
(Philadelphia, April 15, 2026) – abrdn National Municipal Income Fund (NYSE: VFL) announces that the Board of Trustees has approved the removal of a non-fundamental investment policy that restricted VFL from investing more than 20% of its portfolio in high-yield municipal securities. This change is effective June 1, 2026.
In reaching this decision, the Board considered, among other things, that removing this non-fundamental investment policy would likely result in higher credit exposure. The Board weighed the modest increase in credit risk against potential benefits, including expanded diversification, greater earnings, higher distributions, and improved long-term, risk-adjusted returns. The Board concluded that the broader investment mandate would better position VFL to serve shareholders. Additional details can be found on VFL's website at the following link: www.aberdeenvfl.com.
Following the effective date of June 1, 2026, while the VFL may invest in below investment grade securities without limitation, it is expected that VFL will increase its exposure to high-yield securities in stages, moving to approximately 30% of the portfolio initially, and approximately 30% to 50%, depending on market conditions, over time.
Important Information
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.
