Letter to Shareholders (unaudited)

Dear Shareholder,
We present the Annual Report, which covers the activities of abrdn National Municipal Income Fund (the “Fund”), for the fiscal year ended September 30, 2025. The Fund’s investment objective is to seek to provide current income exempt from regular federal income tax, consistent with the preservation of capital.
Total Investment Return1
For the fiscal year ended September 30, 2025, the total return to shareholders of the Fund based on the net asset value (“NAV”) and market price of the Fund, respectively, compared to the Fund’s benchmark, is as follows:

NAV2,3 | -2.69%
Market Price2 | -2.56%
Bloomberg Municipal Bond Index4 | 1.39%

For more information about Fund performance, please visit the Fund on the web at www.aberdeenvfl.com. Here, you can view quarterly commentary on the Fund's performance, monthly fact sheets, distribution and performance information, and other Fund literature.
NAV, Market Price and Premium(+)/Discount(-)
The below table represents a comparison between the current fiscal year end and the prior fiscal year end of the Fund's market price to NAV and associated Premium(+) and Discount(-).

| NAV | Closing Market Price | Premium(+)/ Discount(-)
9/30/2025 | $11.31 | $10.26 | -9.28%
9/30/2024 | $12.33 | $11.17 | -9.41%

During the fiscal year ended September 30, 2025, the Fund’s NAV was within a range of $10.34 to $12.41 and the Fund’s market price traded within a range of $9.33 to $11.33. During the fiscal year ended September 30, 2025, the Fund’s shares traded within a range of a premium(+)/discount(-) of -7.64% to -14.68%.
Aberdeen Name Change
On March 4, 2025, abrdn plc, the parent company of the Fund's adviser, announced that it would change its name, and from that date, will use 'Aberdeen' as the principal trading identity for its Investments business. On March 12, 2025, abrdn plc completed the steps to legally change its name to Aberdeen Group plc. Aberdeen has retained 'abrdn' as an operational abbreviation across its subsidiary legal entities (including the Fund's adviser, fund names and descriptors).
Distribution Policy
Distributions to common shareholders for the fiscal year ended September 30, 2025 totaled $0.60 per share. Based on the market price of $10.26 on September 30, 2025, the annualized distribution was 5.85%. Based on the NAV of $11.31 on September 30, 2025, the annualized distribution rate was 5.31%. Since all distributions are paid after deducting applicable withholding taxes, the effective distribution rate may be higher for those investors who are able to claim a tax credit.
On October 9, 2025 and November 11, 2025 the Fund announced that it will pay on October 31, 2025 and November 28, 2025, respectively a distribution of $0.0500 per share to all shareholders of record as of October 24, 2025 and November 21, 2025, respectively.
The Fund's policy is to provide common shareholders with a stable monthly distribution out of current income. This policy is subject to an annual review as well as regular review at the Board of Trustees' (the "Board") quarterly meetings, unless market conditions require an earlier evaluation.

Open Market Repurchase Program
On September 11, 2024, the Fund publicly announced that the Board of Trustees had approved an open market share repurchase program (the “Program”). Under the terms of the Program, the Fund is permitted to repurchase up to 10% of its outstanding shares of common stock in the open market during any 12 month period as of September 30 of the prior year. The Program allows the Fund to purchase, in the open market, its outstanding common shares, with the amount and timing of any repurchase determined at the discretion of the Fund's investment adviser. Such purchases may be made opportunistically at certain discounts to NAV per share in the reasonable judgment of management based on historical discount levels and current market conditions. On a quarterly basis, the Fund's Board will receive information on any transactions made pursuant to this Program during the prior quarter. If shares are repurchased, the Fund reports repurchase activity on the Fund's website on a monthly basis. For the fiscal year ended September 30, 2025, the Fund did not repurchase any shares through the Program.
Unclaimed Share Accounts
Please be advised that abandoned or unclaimed property laws for certain states require financial organizations to transfer (escheat) unclaimed property (including Fund shares) to the state. Each state has its own definition of unclaimed property, and Fund shares could be considered “unclaimed property” due to account inactivity (e.g., no owner-generated activity for a certain period), returned mail (e.g., when mail sent to a shareholder is returned to the Fund's transfer agent as undeliverable), or a combination of both. If your Fund shares are categorized as unclaimed, your financial advisor or the Fund's transfer agent will follow the applicable state’s statutory requirements to contact you, but if unsuccessful, laws may require that the shares be escheated to the appropriate state. If this happens, you will have to contact the state to recover your property, which may involve time and expense. For more information on unclaimed property and how to maintain an active account, please contact your financial adviser or the Fund's transfer agent.
Portfolio Holdings Disclosure
The Fund's complete schedule of portfolio holdings for the second and fourth quarters of each fiscal year are included in the Fund's semi-annual and annual reports to shareholders. The Fund files its complete schedule of portfolio holdings with the Securities and Exchange Commission (the “SEC”) for the first and third quarters of each fiscal year as an exhibit to its reports on Form N-PORT. These reports are available on the SEC’s website at www.sec.gov. The Fund makes the information available to shareholders upon request and without charge by calling Investor Relations toll-free at 1-800-522-5465.
Proxy Voting
A description of the policies and procedures that the Fund uses to determine how to vote proxies relating to portfolio securities and information regarding how the Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available by August 31 of the relevant year: (1) upon request without charge by calling Investor Relations toll-free at 1-800-522-5465; and (2) on the SEC’s website at www.sec.gov.

Performance Review
For the fiscal year ended September 30, 2025, the abrdn National Municipal Income Fund (VFL) returned -2.69%1 on a net asset value2 basis. This compared to a return of 1.39% for our performance target, the Bloomberg Municipal Bond Index3. On a market-price basis for the same period, the shares returned -2.56%. The Fund's unlevered NAV return was -1.24% for the 12-month reporting period ended September 30, 2025, demonstrating that the leverage detracted an incremental 1.45% to fund performance over that timeframe.
Market Review
The municipal bond market, as measured by the Bloomberg Municipal Bond Index, ended the 12-month period modestly higher than VFL at 1.39%. The U.S. Federal Reserve’s (Fed’s) pause on cutting interest rates cycle combined with elevated issuance and uncertainty around tax legislation led to underperformance with respect to both the long duration and high yield corners of the municipal bond market.
Early in the review period, the Fed lowered the target range for the federal funds rate in both November (by 50 basis points) and December 2024 (by another 25 basis points) but noted its intention to take a data-dependent approach. Meanwhile, President Donald Trump’s election victory and his plans for pro-growth policies helped investor sentiment. However, as the period progressed, concerns grew over the economic impact of the administration’s policies, such as higher tariffs and tighter immigration controls. Markets were volatile in April 2025 following the “Liberation Day” tariff announcements before rebounding later in the month after most of these tariffs were paused. During this period rates in the municipal market moved up 15-20 basis points daily and primary deals were postponed due to the volatility and outflows putting a strain on liquidity. In May, the U.S. and China agreed to implement substantial reciprocal tariff reductions for 90 days4, which supported bond markets. Investors’ focus then shifted to the violence in the Middle
East although a U.S.-brokered ceasefire between Israel and Iran reduced tensions in the region.
Later in the period, the mid-August extension of the U.S.-China tariff truce was a key positive event. The U.S. also reached new trading agreements with the European Union and Japan, reducing tariffs on most of their products to 15%4. However, optimism was tempered by President Trump’s announcement of 100%4 tariffs on branded and patented pharmaceutical imports (although companies building manufacturing facilities in the U.S. were exempted) and higher duties on goods from Canada, India, and Brazil, alongside expanded steel and aluminium tariffs. Meanwhile, the Fed lowered the federal funds rate by 25 basis points to 4.00–4.25%5, describing it as a “risk management” cut that supported bond markets. The interest rate cut along with a slowing pace of primary supply towards the end of the period provided a more constructive environment for market performance, particularly long duration investors. The review period ended with a partial U.S. government shutdown after Congress failed to agree a funding deal. The resulting loss of output and income is expected to weigh on short-term growth, while delays to key data releases could weigh on investor confidence.
Meanwhile, U.S. GDP grew by 3.8%6 on an annualised basis in the second quarter of 2025, which was above estimates, demonstrating a bounce back from previously subdued growth in the first quarter of 2025. The yield7 spread8 between two- and 10-year Treasuries increased as steepening of the curve9 took shape, beginning the review period at a 12 basis points spread and ending at 53 basis points spread10.
Portfolio Review
The Fund maintained its focus on income-generating opportunities amid market volatility driven by Fed policy and macroeconomic uncertainty. While the Fund’s emphasis on income and longer duration resulted in some underperformance in total returns for the

year, we believe looser financial conditions ahead will benefit our strategy. In addition, the high yield sector lagged during the period, but with stable fundamentals and low distressed rates, we remain positive on both lower investment grade and high yield bonds moving forward.
In late 2024, we found income-generating opportunities in lower investment grade and non-investment grade11 issuers in credits with strong fundamentals that stand to benefit from macroeconomic tailwinds12. This resulted in a lower exposure to school districts, states, and territories, and airport sectors in favor of higher exposure to the housing, industrial, and healthcare sectors.
This trend continued into 2025, where we found historic opportunities for relative value in high-quality AA and non-investment grade issuers. During periods of volatility13 throughout the year, we found attractive relative value opportunities in high-quality14 issuers. Portfolio adjustments resulted in further reduced exposure to education in favor of continued higher exposure to sectors that have demonstrated income-generating opportunities, such as housing, airports, and healthcare sectors. Overall, the portfolio’s credit quality profile remained balanced, with incremental adjustments reflecting our ongoing emphasis on income as well as resilient sectors and issuers positioned to benefit from the current environment.
During the period, our allocation to long duration structures detracted from relative performance as the Fed’s accommodative cycle took an extended pause during the period. Hospital, lease-backed, and tobacco bonds underperformed at the sector level and became detractors. Despite this period of underperformance, we remain optimistic that current macroeconomic conditions – particularly the possibility of lower interest rates – should ultimately enhance these issuers' relative value in the market. Conversely, toll and turnpike, health, and industrial revenue bonds contributed
positively. Our expectation is that in addition, leverage15 costs remained elevated, albeit less so than the previous year with the Securities Industry and Financial Markets Association rate averaging 3.04% during the period, down from 3.46% the previous year16.
At the issuer level, notable detractors from relative performance included Golden State Tobacco and Metropolitan Pier and Exposition Authority, these bonds lagged in performance due to their low coupon and long duration structures, however we remain constructive on these structures in an environment of easing financial conditions and expect these to contribute to total return going forward. In contrast, New Hope Cultural Education Authority and Puerto Rico’s GDB Debt Recovery Authority were among the positive contributors.
The monthly distribution reflects the Fund's current policy of providing shareholders with a relatively stable cash flow per share. This policy did not have a material effect on the Fund's investment strategy over the reporting period. During the 12-month period ended September 30, 2025, the distributions were comprised of ordinary income, return of capital and tax exempt distributions.
Outlook
As we move into the fourth quarter, we maintain a cautiously optimistic outlook for the municipal bond market. The current environment continues to support a constructive approach to duration17, which remains a core element of the Fund’s strategy. With the long end of the municipal curve18 offering attractive yields, we are comfortable maintaining, and where appropriate, modestly extending duration to capture yield for shareholders.
Fundamentals remain supportive: tax collections are up year over year and the overall credit picture in municipals is stable. Technicals are also favorable, with fund flows totalling US$31.6 billion year to date19

Typically, ratings are expressed as letter grades that range, for example, from AAA to D to communicate the agency’s opinion of relative level of credit risk. Ratings from AA to CCC may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories.

and issuance up 12%20 compared to the same period last year. We anticipate this relatively elevated pace of issuance to persist, with projections for US$525–575 billion for the year21.Against this backdrop, the portfolio continues to emphasize credit fundamentals while selectively adding to lower credit quality names as opportunities arise to lock in attractive yields. We continue to find value in select issuers and sectors that may outperform in a slowing economic environment. A disciplined approach to credit selection, combined with a constructive duration profile, should help support the Fund’s yield objectives and provide insulation against volatility as market conditions evolve.

| 1 Year | 3 Years | 5 Years | 10 Years
Net Asset Value (NAV) | -2.69% | 5.65% | 0.18% | 2.31%
Market Price | -2.56% | 3.20% | 1.25% | 2.70%

Performance of a $10,000 Investment (as of September 30, 2025)
This graph shows the change in value of a hypothetical investment of $10,000 in the Fund for the periods indicated. For comparison, the same investment is shown in the indicated index.
abrdn Inc. (the "Investment Manager") assumed responsibility for the management of the Fund as investment manager at the close of business on July 7, 2023. Performance prior to this date reflects the performance of an unaffiliated investment manager.
The performance above reflects fee waivers and/or expense reimbursements made by the Fund’s current investment manager. Absent such waivers and/or reimbursements, the Fund’s returns would be lower. Additionally, Aberdeen entered into an agreement with the Fund to limit investor relations services fees. This agreement aligns with the term of the management agreement and may not be terminated prior to the end of the current term of the advisory agreement. See Note 3 in the Notes to Financial Statements.
Returns represent past performance. Total investment return at NAV is based on changes in the NAV of Fund shares and assumes reinvestment of dividends and distributions, if any, at market prices pursuant to the dividend reinvestment program sponsored by the Fund’s transfer agent. All return data at NAV includes fees charged to the Fund, which are listed in the Fund’s Statement of Operations under “Expenses.” Total investment return at market value is based on changes in the market price at which the Fund’s shares traded on the NYSE American during the period and assumes reinvestment of dividends and distributions, if any, at market prices pursuant to the dividend reinvestment program sponsored by the Fund’s transfer agent. The Fund’s total investment return is based on the reported NAV on the financial reporting period ended September 30, 2025. Because the Fund’s shares trade in the stock market based on investor demand, the Fund may trade at a price higher or lower than its NAV. Therefore, returns are calculated based on both market price and NAV. Past performance is no guarantee of future results. The performance information provided does not reflect the deduction of taxes that a shareholder would pay on distributions received from the Fund or the sale of Fund shares. The current performance of the Fund may be lower or higher than the figures shown. The Fund’s yield, return, market price and NAV will fluctuate. Performance information current to the most recent month-end is available at www.aberdeenvfl.com or by calling 800-522-5465.
The gross operating expense ratio excluding fee waivers based on the fiscal year ended September 30, 2025 was 3.99%. The net operating expense ratio net of fee waivers based on the fiscal year ended September 30, 2025 was 3.87%.The net operating expenses net of fee waivers and excluding dividend expense based on the fiscal year ended September 30, 2025 was 1.07%.

(h) | In March 2012, the Fund issued a series of 300 variable rate preferred shares, with a liquidation preference of $100,000 per share (Series 2017 Shares). The Series 2017 Shares were redeemed on February 2, 2016 and replaced with Series 2021 Shares, which were the same amount and value as the Fund’s Series 2017 Shares. On April 25, 2019, the Fund redeemed the Series 2021 Shares, and replaced them with Series 2049 Muni-MultiMode Preferred Shares (Series 2049), which have the same amount and value as the Series 2021 Shares. When the Fund acquired Delaware Investments Colorado Municipal Income Fund, Inc. and Delaware Investments Minnesota Municipal Income Fund II, Inc. on February 11, 2022, it also acquired the Series 2049 preferred shares used as leverage by those funds, which are reflected in the value of preferred shares outstanding in the table above. 36,000,000 were redeemed to fund the tender offer on December 16, 2022. Net asset coverage per share of preferred shares is calculated by dividing net assets as of each fiscal period end plus the amount of any borrowings for investment purposes outstanding as of each fiscal period end by the number of preferred shares outstanding as of such date.

Notes to Financial Statements
September 30, 2025

1. Organization
abrdn National Municipal Income Fund (the “Fund”) is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as a closed-end management investment company. The Fund is diversified for purposes of the 1940 Act. The Fund’s investment objective is to seek to provide current income exempt from regular federal income tax, consistent with the preservation of capital.
2. Summary of Significant Accounting Policies
The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 946 Financial Services-Investment Companies. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The policies conform to generally accepted accounting principles in the United States of America ("U.S. GAAP"). The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income and expenses for the period. Actual results could differ from those estimates. The accounting records of the Fund are maintained in U.S. Dollars and the U.S. Dollar is used as both the functional and reporting currency.
a. Security Valuation:
The Fund values its securities at fair value, consistent with regulatory requirements. "Fair value" is defined in the Fund's Valuation and Liquidity Procedures as the price that could be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants without a compulsion to transact at the measurement date, also referred to as market value. Pursuant to Rule 2a-5 under the 1940 Act, the Board of Trustees (the "Board") designated abrdn Inc. (the "Manager" or "Aberdeen"), the Fund's Investment Manager, as the valuation designee ("Valuation Designee") for the Fund to perform the fair value determinations relating to Fund investments for which market quotations are not readily available or deemed unreliable.
In accordance with the authoritative guidance on fair value measurements and disclosures under U.S. GAAP, the Fund discloses the fair value of its investments using a three-level hierarchy that classifies the inputs to valuation techniques used to measure the fair value. The hierarchy assigns Level 1, the highest level, measurements to valuations based upon unadjusted quoted prices in active markets for identical assets, Level 2 measurements to valuations based upon other significant observable inputs, including adjusted quoted prices in active markets for similar assets, and Level 3, the lowest level, measurements to valuations based upon unobservable inputs that are
significant to the valuation. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk, for example, the risk inherent in a particular valuation technique used to measure fair value including a pricing model and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability, which are based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. A financial instrument’s level within the fair value hierarchy is based upon the lowest level of any input that is significant to the fair value measurement.
Open-end mutual funds are valued at the respective net asset value (“NAV”) as reported by such company. The prospectuses for the registered open-end management investment companies in which the Fund invests explain the circumstances under which those companies will use fair value pricing and the effects of using fair value pricing. Closed-end funds and exchange-traded funds ("ETFs") are valued at the market price of the security at the Valuation Time (defined below). A security using any of these pricing methodologies is generally determined to be a Level 1 investment.
Long-term debt and other fixed-income securities are valued at the last quoted or evaluated bid price on the valuation date provided by an independent pricing service provider. If there are no current day bids, the security is valued at the previously applied bid. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size and the strategies employed by the Valuation Designee generally trade in round lot sizes. In certain circumstances, some trades may occur in smaller “odd lot” sizes which may be effected at lower, or higher, prices than institutional round lot trades. Short-term debt securities (such as commercial paper and U.S. treasury bills) having a remaining maturity of 60 days or less are valued at the last quoted or evaluated bid price on the valuation date provided by an independent pricing service, or on the basis of amortized cost, if it represents the best approximation of fair value. Debt and other fixed-income securities are generally determined to be Level 2 investments.
Short-term investments are comprised of cash and cash equivalents invested in short-term investment funds which are redeemable daily. Generally, these investment types are categorized as Level 1 investments.
In the event that a security’s market quotations are not readily available or are deemed unreliable (for reasons other than because the foreign exchange on which it trades closes before the Valuation Time), the security is valued at fair value as determined by the Valuation

abrdn National Municipal Income Fund | 19

Notes to Financial Statements (continued)
September 30, 2025

Designee, taking into account the relevant factors and surrounding circumstances using valuation policies and procedures approved by the Board. A security that has been fair valued by the Valuation Designee may be classified as Level 2 or Level 3 depending on the nature of the inputs.
The three-level hierarchy of inputs is summarized below:
Level 1 - quoted prices (unadjusted) in active markets for identical investments;
Level 2 - other significant observable inputs (including valuation factors, quoted prices for similar securities, interest rates, prepayment speeds, and credit risk, etc.); or
Level 3 - significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).
A summary of standard inputs is listed below:

Security Type | Standard Inputs
Debt and other fixed-income securities | Reported trade data, broker-dealer price quotations, benchmark yields, issuer spreads on comparable securities, credit quality, yield, and maturity.

The following is a summary of the inputs used as of September 30, 2025 in valuing the Fund's investments and other financial instruments at fair value. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. Please refer to the Portfolio of Investments for a detailed breakout of the security types:

Investments, at Value | Level 1 – Quoted Prices | Level 2 – Other Significant Observable Inputs | Level 3 – Significant Unobservable Inputs | Total
Assets |  |
Investments in Securities |  |  |
Municipal Bonds | $– | $235,143,943 | $– | $235,143,943
Total Investments | $– | $235,143,943 | $– | $235,143,943
Total Investment Assets | $– | $235,143,943 | $– | $235,143,943

Amounts listed as “–” are $0 or round to $0.
b. Restricted Securities:
Restricted securities are privately-placed securities whose resale is restricted under U.S. securities laws. The Fund may invest in restricted securities, including unregistered securities eligible for resale without registration pursuant to Rule 144A and privately-placed securities of U.S. and non-U.S. issuers offered outside the U.S. without registration pursuant to Regulation S under the Securities Act of 1933, as amended (the "1933 Act"). Rule 144A securities may be freely traded among certain qualified institutional investors, such as the Fund, but resale of such securities in the U.S. is permitted only in limited circumstances.
c. Security Transactions, Investment Income and Expenses:
Security transactions are recorded on the trade date. Realized and unrealized gains/(losses) from security and foreign currency transactions are calculated on the identified cost basis.
Dividend Income and corporate actions are recorded generally on the ex-dividend date, except for certain dividends and corporate actions which may be recorded after the ex-dividend date, as soon as the Fund acquires information regarding such dividends or corporate actions. Interest income and expenses are recorded on an accrual basis.
Discounts and premiums on securities purchased are accreted or amortized on an effective yield basis over the estimated lives of the respective securities.
d. Distributions:
The Fund intends to make regular monthly distributions of net investment income to holders of common shares. The Fund expects to pay its common shareholders annually all or substantially all of its investment company taxable income. In addition, at least annually, the Fund intends to distribute all or substantially all of its net capital gains, if any.
Distributions from net realized gains for book purposes may include short-term capital gains which are ordinary income for tax purposes. Distributions to common shareholders are recorded on the ex-dividend date.
Dividends and distributions to shareholders are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These “book-tax” differences are considered either temporary or permanent in nature. To the extent these differences are

20 | abrdn National Municipal Income Fund

Notes to Financial Statements (continued)
September 30, 2025

permanent in nature, such amounts are reclassified within the capital accounts based on their federal income tax treatment. Temporary differences do not require reclassification. To the extent distributions exceed current and accumulated earnings and profits for federal income tax purposes they are reported to shareholders as return of capital.
e. Federal Income Taxes:
The Fund intends to continue to qualify as a “regulated investment company” ("RIC") by complying with the provisions available to certain investment companies, as defined in Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"), and to make distributions of net investment income and net realized capital gains sufficient to relieve the Fund from all federal income taxes. Therefore, no federal income tax provision is required.
The Fund recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. Management of the Fund has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Since tax authorities can examine previously filed tax returns, the Fund's U.S. federal and state tax returns for each of the most recent four fiscal years up to the most recent fiscal year ended September 30, 2025 are subject to such review.
3. Agreements and Transactions with Affiliates
a. Investment Manager:
Aberdeen serves as the Fund’s Investment Manager pursuant to an investment management agreement (the “Management Agreement”) with the Fund. The Investment Manager is a wholly-owned indirect subsidiary of Aberdeen Group plc. In rendering management services, the Investment Manager may use the resources of investment advisor subsidiaries of Aberdeen Group plc. These affiliates have entered into procedures pursuant to which investment professionals from affiliates may render portfolio management and research services as associated persons of the Investment Manager.
As compensation for its services to the Fund, the Investment Manager receives an annual investment management fee at an annual rate of 0.40% of the average daily "Managed Assets" of the Fund during the month. "Managed Assets" are the total assets of the Fund (including any assets attributable to money borrowed for investment purposes, including proceeds from (and assets subject to) reverse repurchase agreements, any credit facility and any issuance of preferred shares or notes) minus the sum of the Fund's accrued liabilities (other than Fund liabilities incurred for the purpose of leverage). For the fiscal year ended September 30, 2025, the Fund paid the Investment Manager $954,241.
The Investment Manager entered into a written contract (the “Expense Limitation Agreement”) with the Fund that is effective through June 30, 2026. The Expense Limitation Agreement limits the total ordinary operating expenses of the Fund (excluding any leverage costs, taxes, interest, brokerage commissions, dividend expenses and any non-routine expenses) from exceeding 1.07% of the average daily net assets of the Fund on an annualized basis. The total amount of the waiver for the fiscal year ended September 30, 2025 pursuant to the Expense Limitation Agreement was $167,122.
The Investment Manager may request and receive reimbursement from the Fund of the management fees waived and other expenses reimbursed pursuant to the Expense Limitation Agreement as of a date not more than three years after the date when the Investment Manager limited the fees or reimbursed the expenses; provided that the following requirements are met: the reimbursements do not cause the Fund to exceed the lesser of the applicable expense limitation in the contract at the time the fees were limited or expenses are paid or the applicable expense limitation in effect at the time the expenses are being recouped by the Investment Manager, and the payment of such reimbursement is approved by the Board on a quarterly basis (the “Reimbursement Requirements”).
As of September 30, 2025, to the extent the Reimbursement Requirements are met, the cumulative potential reimbursements to the Investment Manager from the Fund, based on expenses reimbursed by the Investment Manager, including adjustments described above, would be:

Amount Fiscal Period 2023(Expires 09/30/26) |  | $325,793
Amount Fiscal Year 2024 (Expires 09/30/27) |  | $181,437
Amount Fiscal Year 2025 (Expires 09/30/28) |  | $167,122
Total* |  | $674,352

* | Amounts reported are due to expire throughout the respective 3-year expiration period presented above.

b. Fund Administrator:
Aberdeen is the Fund’s Administrator. Pursuant to the Administration Agreement, Aberdeen receives a fee paid by the Fund, at an annual fee rate of 0.08% of the Fund’s average daily net assets. State Street Bank and Trust Company serves as the Fund's Sub-Administrator. For the fiscal year ended September 30, 2025 pursuant to the Administration Agreement, Aberdeen earned $190,848 from the Fund for administration services.
c. Investor Relations:
Under the terms of the Investor Relations Services Agreement, Aberdeen provides and/or engages third parties to provide investor relations services to the Fund and certain other funds advised by the Investment Manager or its affiliates as part of an Investor Relations Program. Under the Investor Relations Services Agreement, the Fund

abrdn National Municipal Income Fund | 21

Notes to Financial Statements (continued)
September 30, 2025

owes a portion of the fees related to the Investor Relations Program (the “Fund’s Portion”). However, Investor Relations Services fees are limited by Aberdeen so that the Fund will only pay up to an annual rate of 0.05% of the Fund’s average weekly net assets. Any difference between the capped rate of 0.05% of the Fund’s average weekly net assets and the Fund’s Portion is paid for by Aberdeen.
Pursuant to the terms of the Investor Relations Services Agreement, Aberdeen (or third parties engaged by Aberdeen), among other things, provides objective and timely information to shareholders based on publicly-available information; provides information efficiently through the use of technology while offering shareholders immediate access to knowledgeable investor relations representatives; develops and maintains effective communications with investment professionals from a wide variety of firms; creates and maintains investor relations communication materials such as fund manager interviews, films and webcasts, publishes white papers, magazine articles and other relevant materials discussing the Fund’s investment results, portfolio positioning and outlook; develops and maintains effective communications with large institutional shareholders; responds to specific shareholder questions; and reports activities and results to the Board and management detailing insight into general shareholder sentiment.
During the fiscal year ended September 30, 2025, the Fund incurred investor relations fees of approximately $52,748. For the fiscal year ended September 30, 2025, Aberdeen did not contribute to the investor relations fees for the Fund because the Fund's contribution was below 0.05% of the Fund's average weekly net assets on an annual basis.
d. Purchase/Sale Transactions Between Affiliates
The Fund is permitted to buy or sell securities with funds that have a common investment manager (or investment advisers which are affiliates) under specific procedures which have been approved by the Board. The procedures are designed to satisfy the requirements of Rule 17a-7 of the 1940 Act (“Rule 17a-7”). During the fiscal year ended September 30, 2025, the Fund did not engage in any purchases of securities pursuant to Rule 17a-7.
4. Investment Transactions
Purchases and sales of investment securities (excluding short-term securities) for the fiscal year ended September 30, 2025, were $136,806,055 and $139,397,562, respectively.
5. Capital
The Fund is authorized to issue an unlimited number of common shares of beneficial interest at par value $0.001 per common share. As of September 30, 2025, there were 12,278,003 shares of common stock issued and outstanding. Shares issuable under the Fund’s
dividend reinvestment plan are purchased by the Fund’s transfer agent, Computershare, Inc., in the open market. During the fiscal year ended September 30, 2025, the Fund did not issue any shares under its dividend reinvestment plan.
6. Open Market Repurchase Program
On September 11, 2024, the Fund publicly announced that the Board of Trustees had approved an open market share repurchase program(the “Program”). Under the terms of the Program, the Fund is permitted to repurchase up to 10% of its outstanding shares of common stock in the open market during any 12 month period as of September 30 of the prior year. The Program allows the Fund to purchase, in the open market, its outstanding common shares, with the amount and timing of any repurchase determined at the discretion of the Fund's investment adviser. Such purchases may be made opportunistically at certain discounts to NAV per share in the reasonable judgment of management based on historical discount levels and current market conditions. On a quarterly basis, the Fund's Board will receive information on any transactions made pursuant to this Program during the prior quarter. If shares are repurchased, the Fund reports repurchase activity on the Fund's website on a monthly basis. For the fiscal year ended September 30, 2025, the Fund did not repurchase any shares through the Program.
7. Muni-MultiMode Preferred Shares
On April 25, 2019, the Fund priced private offerings to a qualified institutional buyer, as defined pursuant to Rule 144A under the 1933 Act, of approximately $30 million of Muni-MultiMode Preferred Shares, Series 2049 ("MMP"), with a $100,000 liquidation value per share. The Fund used the net proceeds from each offering to redeem its outstanding Variable Rate MuniFund Term Preferred Shares, Series 2021 ("VMTP"). The Fund issued MMP shares in the same amount and value as its previously outstanding VMTP shares. On February 11, 2022, the Fund acquired the assets of Delaware Investments Colorado Municipal Income Fund, Inc. (“VCF”) and Delaware Investments Minnesota Municipal Income Fund II, Inc. (“VMM”), which included Series 2049 MMP preferred shares issued by each of VCF and VMM used as leverage (the “Reorganization”). The Reorganization caused the Fund’s total preferred shares outstanding to equal $135 million, with VCF’s Series 2049 MMP preferred shares becoming Series 2 and VMM’s Series 2049 MMP preferred shares becoming Series 3 of the MMP shares issued by the Fund. The Fund’s original tranche of Series 2049 MMP preferred shares is Series 1. The terms of the Series 2 and Series 3 MMP shares are substantially similar to those of the Series 1. In connection with the 2022 tender offer the Fund accordingly reduced its outstanding MMP Preferred Shares by redeeming 360 Preferred Shares at the $100,000 liquidation preference per share, plus an additional amount representing the final accumulated dividend amounts owed to be paid to preferred shareholders. The redemption

22 | abrdn National Municipal Income Fund

Notes to Financial Statements (continued)
September 30, 2025

occurred on December 20, 2022. After this the total preferred shares outstanding was $99,000,000.
The MMP shares are a floating rate form of preferred stock with a mandatory term redemption. The mandatory term redemption date for these offerings is April 1, 2049. MMP shares have the option at either the request of the purchaser or issuer to be converted to a variable rate demand preferred (“VRDP”) structure. The converted VRDP shares could then be offered for sale to certain institutional investors. The VRDP could continue to remain outstanding for the remainder of the MMP shares’ 30-year term. MMP dividends are set weekly at a spread to the Securities Industry and Financial Markets Association Municipal Swap Index. MMP shares represent the preferred stock of the Fund and are senior, with priority in all respects, to the Fund’s common shares as to payments of dividends. MMP shares are redeemable at par. The Fund may be obligated to redeem certain of the MMP shares if the Fund fails to maintain certain asset coverage and leverage ratio requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation value per share plus any accumulated but unpaid dividends. Dividends on MMP shares are set weekly, and are based on a short-term index rate plus an additional spread that is subject to adjustment in certain circumstances, including a change in the credit rating assigned to the MMP shares by Fitch Ratings (“Fitch”).
The weighted average dividend rate for all of the Fund’s MMP shares for the fiscal year ended September 30, 2025 is 2.78%. The average balance for the fiscal year ended September 30, 2025 was $99,000,000.
The Fund uses leverage because its managers believe that, over time, leveraging may provide opportunities for additional income and total return for common shareholders. However, the use of leverage also can expose common shareholders to additional volatility. For example, as the prices of securities held by the Fund decline, the negative impact of these valuation changes on common share NAV and common shareholder total return is magnified by the use of leverage; accordingly, the use of structural leverage may hurt the Fund’s overall performance. Leverage may also cause the Fund to incur certain costs. In the event that the Fund is unable to meet certain criteria (including, but not limited to, maintaining certain ratings with Fitch, funding dividend payments, or funding redemptions), the Fund will pay additional fees with respect to the leverage.
For financial reporting purposes, the MMP shares are considered debt of the issuer; therefore, the liquidation value which approximates fair value of the MMP shares is recorded as a liability in the "Statement of assets and liabilities". Dividends accrued and paid on the MMP shares are included as a component of dividend expense on preferred shares in the "Statement of operations". The MMP shares are treated as equity
for legal and tax purposes. Dividends paid to holders of the MMP shares are generally classified as tax-exempt income for tax-reporting purposes.
8. Portfolio Investment Risks
a. Credit and Market Risk:
A debt instrument’s price depends, in part, on the credit quality of the issuer, borrower, counterparty, or underlying collateral and can decline in response to changes in the actual or perceived financial condition of the issuer, borrower, counterparty, or underlying collateral, or changes in specific or general market, economic, industry, political, regulatory, geopolitical, or other conditions. Funds that invest in high yield and emerging market instruments are subject to certain additional credit and market risks. The yields of high yield and emerging market debt obligations reflect, among other things, perceived credit risk. The Fund's investments in securities rated below investment grade typically involve risks not associated with higher rated securities including, among others, greater risk of not receiving timely and/or ultimate payment of interest and principal, greater market price volatility, and less liquid secondary market trading.
b. Geographic Focus Risk:
The Fund's performance could be more volatile than that of a more geographically diversified fund and could be significantly impacted as a result of the Fund investing a large percentage of its assets in issuers located in a single state, small number of states, or a particular geographic region. Also, the Fund's performance may be more closely tied to the market, economic, or regulatory conditions in those states, regions, or municipalities.
c. High-Yield Bonds and Other Lower-Rated Securities Risk:
The Fund’s 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.
d. Interest Rate Risk:
The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments. Generally, the Fund’s fixed income securities will decrease in value if interest rates rise and vice versa, and the volatility of lower-rated securities is even greater than that of higher-rated

abrdn National Municipal Income Fund | 23

Notes to Financial Statements (continued)
September 30, 2025

securities. Also, longer-term securities are generally more volatile, so the average maturity or duration of these securities affects risk. The Fund may be subject to a greater interest rate risk due to a changing interest rate environment and the effect of potential government monetary and fiscal policy initiatives and resulting market reaction to those initiatives.
Changes in interest rates or a lack of market participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, making it more difficult for the Fund to sell its holdings.
e. Issuer Risk:
The value of a security may decline for reasons directly related to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods or services. In an increasingly interconnected financial market, the adverse changes in the financial conditions of one issuer may negatively affect other issuers.
f. Municipal Securities Risk
The Fund is subjected to municipal securities risk. Municipal bonds can be significantly affected by political and economic changes, including inflation, as well as uncertainties in the municipal market related to taxation, legislative changes, or the rights of municipal security holders. Municipal bonds have varying levels of sensitivity to changes in interest rates. Interest rate risk is generally lower for shorter-term municipal bonds and higher for long term municipal bonds.
Municipal Bond Tax Risk. A municipal bond that is issued as tax-exempt may later be declared to be taxable. In addition, if the federal income tax rate is reduced, the value of the tax exemption may be less valuable, causing the value of a municipal bond to decline.
Municipal Market Volatility and Illiquidity Risk. The municipal bond market can be volatile, particularly for lower-rated and unrated securities. Liquidity can be reduced unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds without the sale significantly changing the market value of the bond. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices.
Municipal Sector Risk. From time to time the Fund may invest a substantial amount of its assets in municipal securities whose interest is paid solely from revenues of similar projects. If the Fund concentrates its investments in this manner, it assumes the economic risks relating to such projects and any adverse changes to such projects may have a significant negative impact on the Fund’s investment performance.
g. Sector Risk
To the extent that the Fund has a significant portion of its assets invested in securities of companies conducting business in a broadly related group of industries within an economic sector, the Fund may be more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.
h. Tobacco Related Bonds Risk
The Fund is subject to Tobacco Related Bonds Risk. In 1998, the largest U.S. tobacco manufacturers reached an out of court agreement, the Master Settlement Agreement (“MSA”), to settle claims against them by 46 states and six other U.S. jurisdictions. The tobacco manufacturers agreed to make annual payments to the government entities in exchange for the release of all litigation claims. A number of the states have sold bonds that are backed by those future payments. The Fund may invest in two types of those bonds: (i) bonds that make payments only from a state’s interest in the MSA and (ii) bonds that make payments from both the MSA revenue and from an “appropriation pledge” by the state. An “appropriation pledge” requires the state to pass a specific periodic appropriation to make the payments and is generally not an unconditional guarantee of payment by a state.
The MSA settlement payments are based on factors, including, but not limited to, annual domestic cigarette shipments, cigarette consumption, inflation and the financial capability of participating tobacco companies. Payments could be reduced if consumption decreases, if market share is lost to non-MSA manufacturers, or if there is a negative outcome in litigation regarding the MSA.
The MSA and tobacco manufacturers have been and continue to be subject to various legal claims, including, among others, claims that the MSA violates federal antitrust law. In addition, the United States Department of Justice has alleged in a civil lawsuit that the major tobacco companies defrauded and misled the American public about the health risks associated with smoking cigarettes. An adverse outcome to this lawsuit or to any other litigation matters or regulatory actions relating to the MSA or affecting tobacco manufacturers could adversely affect the payment streams associated with the MSA or cause delays or reductions in bond payments by tobacco manufacturers.
9. Contingencies
In the normal course of business, the Fund may provide general indemnifications pursuant to certain contracts and organizational documents. The Fund's maximum exposure under these arrangements is dependent on future claims that may be made against the Fund, and therefore, cannot be estimated; however, the Fund expects the risk of loss from such claims to be remote.

10. Tax Information
The U.S. federal income tax basis of the Fund's investments (including derivatives, if applicable) and the net unrealized depreciation as of September 30, 2025, were as follows:

Tax Cost of Securities | Unrealized Appreciation | Unrealized Depreciation | Net Unrealized Appreciation/ (Depreciation)
$235,786,441 | $6,448,087 | $(7,090,585) | $(642,498)

The tax character of distributions paid during the fiscal years ended September 30, 2025 and September 30, 2024 was as follows:

| September 30, 2025 | September 30, 2024
Distributions paid from: |  |
Ordinary Income | $107,373 | $-
Tax Exempt Distributions | 7,051,136 | 5,954,833
Return of Capital | 208,293 | -
Total tax character of distributions | $7,366,802 | $5,954,833

Amounts listed as “–” are $0 or round to $0.
As of September 30, 2025, the components of accumulated earnings on a tax basis were as follows:

Undistributed Ordinary Income | $-
Undistributed Long-Term Capital Gains | -
Total undistributed earnings | $-
Accumulated Capital and Other Losses | $-
Capital loss carryforward | $(40,075,487)*
Other currency gains | -
Other Temporary Differences | (426,521)
Unrealized Appreciation/(Depreciation) | (642,498)**
Total accumulated earnings/(losses) – net | $(41,144,506)

Amounts listed as “–” are $0 or round to $0.

* | On September 30, 2025, the Fund had a net capital loss carryforward of $(40,075,487) which will be available to offset like amounts of any future taxable gains. This capital loss carryforward is subject to yearly loss limitations and cannot be used in its entirety at one time. The Fund is permitted to carry forward capital losses for an unlimited period, and capital losses that are carried forward will retain their character as either short-term or long-term capital losses. The breakdown of capital loss carryforwards are as follows:

Amounts | Expires
$20,328,198 | Unlimited (Short—Term)
19,747,289 | Unlimited (Long—Term)

** The difference between book-basis and tax-basis unrealized appreciation/(depreciation) is attributable to book and tax amortization methods for premiums and discounts on fixed income securities and the tax deferral of wash sales.
11. Segment Reporting
In this reporting period, the Fund adopted FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) - Improvements to
Reportable Segment Disclosures ("ASU 2023-07"). Adoption of the new standard impacted disclosures only and did not affect the Fund’s financial position nor the results of its operations. Operating segments are components of a public entity that engage in business activities from which it may recognize revenues and incur expenses, have discrete financial information available, and have their operating results regularly reviewed by the public entity’s chief operating

abrdn National Municipal Income Fund | 25

September 30, 2025

decision maker (“CODM”) when assessing segment performance and making decisions about segment resources. The Chief Financial Officer of the Fund acts as the Fund’s CODM. The CODM monitors the operating results of the Fund as a whole, and the Fund’s asset allocation is managed in accordance with its Prospectus. The Fund operates as a single operating and reporting segment pursuant to its investment objective and principal investment strategy. The Fund’s portfolio composition, total returns, expense ratios and changes in net assets used by the CODM to assess segment performance and make resource allocations are consistent with the information presented within the Fund's financial statements. Segment assets are reflected on the Fund’s Statement of Assets and Liabilities as “Total Assets” and significant segment expenses are listed on the Statement of Operations.
12. Recent Accounting Pronouncements
In December 2023, the FASB issued Accounting Standards Update 2023-09 (“ASU 2023-09”), Income Taxes (Topic 740) Improvements to Income Tax Disclosures, which amends quantitative and qualitative
income tax disclosure requirements in order to increase disclosure consistency, bifurcate income tax information by jurisdiction and remove information that is no longer beneficial. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, and early adoption is permitted. Fund Management is evaluating the impacts of these changes on the Fund’s financial statements.
13. Subsequent Events
Management has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. Based on this evaluation, no disclosures and/or adjustments were required to the financial statements as of September 30, 2025, other than as noted below.
On October 9, 2025 and November 11, 2025 the Fund announced that it will pay on October 31, 2025 and November 28, 2025, respectively a distribution of $0.0500 per share to all shareholders of record as of October 24, 2025 and November 21, 2025, respectively.

The financial highlights for each of the years in the three-year period ended March 31, 2023 were audited by other independent registered public accountants whose report, dated June 9, 2023, expressed an unqualified opinion on those financial highlights.
Basis for Opinion
These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of September 30, 2025, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures.

Summary of Board Considerations in Approving the Investment Management Agreement
At a regularly scheduled meeting (the “Meeting”) of the Board of Trustees (the “Board”) of abrdn National Municipal Income Fund (the “Fund”) held on June 10, 2025, the Board, including those Trustees (the “Independent Trustees”) who are not “interested persons” (as that term is defined in the Investment Company Act of 1940 (the “1940 Act”)) of the Fund, approved the continuation of the investment management agreement (the “Management Agreement”) between abrdn Inc. (the “Investment Manager”) and the Fund. In connection with their consideration of whether to approve the continuation of the Management Agreement, the Board members received and reviewed a variety of information provided by the Investment Manager relating to the Fund, the Management Agreement and the Investment Manager. The information provided to the Board members included (but was not limited to): comparative performance, fee and expense information (as well as information on the limitations of such comparable data) of a peer group of funds based on the Fund’s Morningstar Category (the “Peer Funds”), as selected by Institutional Shareholder Services Inc. (“ISS”), an independent third-party provider of investment company data and other performance information. The Peer Funds presented for fee and expense data comparison consisted of certain of the funds in the Morningstar Category and other industry peers, as determined independently by ISS, and the Peer Funds presented for the performance data comparison consisted of the Fund’s Morningstar category, as determined by ISS. The Board also received information regarding relevant benchmark indices and information regarding the nature, extent and quality of services provided by the Investment Manager under the Management Agreement.
The materials provided to the Board generally included, among other items: (i) information on the investment performance of the Fund, the performance of the Peer Funds, comparable funds, if any, and the Fund’s performance benchmark; (ii) reports prepared by the Investment Manager in response to requests submitted by the Independent Trustees’ independent legal counsel on behalf of such Trustees; (iii) information on the Fund’s management fee and other expenses, including information comparing the Fund’s expenses to the Peer Funds, comparable funds, if any, and information about applicable fee “breakpoints” in the Fund’s fee structure and expense limitations, if any; (iv) information regarding the Investment Manager’ revenues and costs of providing services to the funds and any compensation paid to affiliates of the Investment Manager; and (v) a memorandum from the Independent Trustees’ independent legal counsel on the responsibilities of the Board in considering the approval of the investment advisory arrangement under the 1940 Act and Massachusetts law.
The Independent Trustees met with representatives of the Investment Manager and separately in executive session with independent legal counsel on June 10, 2025 to discuss the continuation of the Management Agreement. The Independent Trustees also met with representatives of the Investment Manager and separately in executive session with independent legal counsel on May 29, 2025 to discuss the materials provided to the Board by the Investment Manager in response to a request for information sent to them by the Independent Trustees’ independent legal counsel.
In evaluating whether to renew the Management Agreement for the Fund, the Board considered numerous factors, including: (i) the nature, extent and quality of services provided to the Fund by the Investment Manager under the Management Agreement; (ii) the costs of services provided to the Fund and the profits realized by the Investment Manager (and its affiliates) from its relationship with the Fund; (iii) the Fund’s total expense ratio as well as the management fee paid by the Fund pursuant to the Management Agreement relative to the total expense ratios of and the management fees charged to the Peer Funds and comparable accounts, if any; (iv) the investment performance of the Fund relative to that of its benchmark index as well as the performance of the Peer Funds and comparable funds, if any; (v) any additional benefits (such as soft dollars, if any) received by the Investment Manager or its affiliates; (vi) the extent to which economies of scale are being realized by shareholders and will be realized as the Fund’s assets increase; (vii) the Investment Manager’s compliance program; and (viii) any other considerations deemed relevant by the Board. The Independent Trustees also discussed the Management Agreement in an executive session with independent legal counsel at which no representatives of the Investment Manager were present. No single factor reviewed by the Board was identified as the principal factor in determining whether to renew the Management Agreement, and individual Trustees may have given different weight to various factors.

Supplemental Information (Unaudited) (continued)

The discussion immediately below outlines in greater detail certain of the materials and information presented to the Board by the Investment Manager in connection with the Board’s consideration and approval of the continuation of the Management Agreement, and the conclusions made by the Board at the Meeting when determining to renew the Management Agreement.
The Nature, Extent and Quality of Services Provided to the Fund Under the Management Agreement
The Trustees considered the nature, extent and quality of services provided by the Investment Manager to the Fund. They reviewed information about the resources dedicated to the Fund by the Investment Manager and its affiliates. Among other things, the Board reviewed and discussed the background and experience of the Investment Manager’s senior management personnel who serviced the Fund and the qualifications, background and responsibilities of the portfolio managers primarily responsible for providing day-to-day portfolio management services for the Fund. The Trustees also considered the financial condition of the Investment Manager and the Investment Manager’s ability to provide quality service to the Fund. Management representatives reported to the Board and responded to questions on, among other things, the Investment Manager’s business plans and any current or proposed organizational changes. The Trustees also took into account the Investment Manager’s experience as an asset manager and considered information regarding the Investment Manager’s compliance with applicable laws and Securities and Exchange Commission (“SEC”) and other regulatory agency inquiries or audits of the Fund, the Investment Manager and/or its affiliates. The Board considered reports from the Investment Manager on its risk management processes. The Board noted that it received information on a regular basis from the Fund’s Chief Compliance Officer regarding the Investment Manager’s compliance policies and procedures and information concerning the Investment Manager’s brokerage policies and practices. The Trustees also noted that the Investment Manager had provided information and periodic reporting, including updates on the management of the Fund and the quality of its performance and had discussed these matters with the Trustees at meetings held regularly throughout the preceding year.
Based on the totality of the information considered, the Board concluded that the nature, extent and quality of the Investment Manager’s services provided to the Fund were of high quality, and that the Investment Manager has provided and could reasonably be expected to continue to provide these services on an ongoing basis based on its experience, operations and resources.
The Costs of Services Provided and Profits Realized by the Investment Manager and its Affiliates from their Relationships with the Fund
The Board reviewed information compiled by ISS that compared the Fund’s effective annual management fee rate with the fees paid by its Peer Funds. The Board reviewed with management the effective annual management fee paid by the Fund to the Investment Manager for investment management services. The Board noted that the Investment Manager and its affiliates did not have any SEC-registered closed-end funds that were directly comparable to the Fund. Although there were no other substantially similar abrdn-advised investment vehicles against which to compare the Fund’s management fees, the Investment Manager provided information for other abrdn-advised products with similar investment strategies to those of the Fund where available. The Board considered the Fund’s management fee structure. The Trustees also considered information from management about the fees charged by the Investment Manager to other clients investing primarily in an asset class similar to that of the Fund. The Board considered the fee comparisons in light of the differences in resources and costs required to manage the different types of accounts. In evaluating the Fund’s management fee, the Board took into account the regulatory regimes, fund structure, level of services, complexity and quality of the investment management of the Fund.
In addition to the foregoing, the Board considered the Fund’s fees and expenses relative to the fees and expenses of the Peer Funds, as well as information on the limitations of such comparable data given differences between the Fund and the Peer Funds presented. The Board noted that, like the Fund, the Peer Funds did not have breakpoints in the advisory fee. This information showed that the Fund’s net management fee was below the median of the Peer Funds but that the Fund’s total net expenses, exclusive of investment-related expenses, were above the median of the Peer Funds. The Board also reviewed the profitability of the investment advisory relationship with the Fund to the Investment Manager. The Board concluded that the Fund’s fees and expenses, as well as the Investment Manager’s profitability, were reasonable in light of the nature, extent and quality of services provided.
Investment Performance of the Fund
The Board received and reviewed with the Fund’s management, among other performance data, information that compared the Fund’s return over various time periods to those of comparable investment companies and discussed this information and other related performance data with management. The Board received and considered information comparing the Fund’s performance to the performance of the Fund’s Peer Funds, including information on the limitations of such comparable data given differences between the Fund and the Peer Funds presented.
In addition, the Board received and reviewed information regarding the Fund’s total return on a gross and net basis and relative to the Fund’s benchmark. The Trustees considered management’s discussion of the factors contributing to differences in performance between the Fund, its Peer Funds, other abrdn strategies, as applicable, and the Fund’s benchmark, including (but not limited to) differences in the investment strategies, restrictions and risks of the Peer Funds and distinguishing features of the Fund relative to the benchmark and other abrdn strategies. Additionally, the Board considered information about the Fund’s discount/premium ranking relative to its Peer Funds and the Manager’s discussion of the Fund’s performance. The Trustees noted that the Fund underperformed its benchmark and the average of the Peer Funds for the 1-, 3-, 5- and 10-year

periods ended March 31, 2025. The Board considered the Investment Manager’s discussion of Fund performance, efforts to improve performance, and the Investment Manager’s plans for the Fund, among other factors, in determining to continue the Management Agreement. The Board also considered the differences between the Fund and the Peer Funds presented, as well as distinctions between the Fund’s strategy and the benchmark.
Direct and Indirect Benefits
The Board then considered whether or the extent to which the Investment Manager derives any direct, ancillary or indirect benefits, such as reputational benefits, that could accrue to the Investment Manager from the Fund’s operations as a result of the Investment Manager’s relationship with the Fund. The Board recognized the services provided to the Fund by affiliates of the Investment Manager and the related compensation paid by the Fund for those services. Based on the totality of the information considered, the Board concluded that any benefits accruing to the Investment Manager by virtue of its relationship with the Fund appeared to be reasonable.
Economies of Scale
The Board next considered management’s discussion of the Fund’s management fee structure and determined that the management fee structure was reasonable. The Board based its determination on various factors, including how the Fund’s management fee compared relative to the Peer Funds. The Board also considered that the Fund had an expense limitation agreement in place until July 10, 2025, pursuant to which the Investment Manager agreed to waive a portion of its advisory fee and/or reimburse certain expenses as a means of limiting the Fund’s total annual operating expenses, and that Management proposed to extend the Expense Limitation Agreement until June 30, 2026. The Board concluded that the economies of scale shared with the Fund were reasonable.
* * *
Based on the Board’s deliberations and its evaluation of the information described above and other factors and information the Trustees deemed relevant in the exercise of their individual reasonable business judgment, the Board, including the Independent Trustees, with the assistance of fund counsel and independent legal counsel to the Independent Trustees, unanimously concluded that the the fees charged pursuant to the Management Agreement were fair and reasonable and approved the continuation of the Management Agreement.

RECENT CHANGES
The following information is a summary of certain changes during the fiscal period ended September 30, 2025. This information may not reflect all of the changes that have occurred since you purchased the Fund.
During the applicable period, there have been: (i) no material changes to the Fund's investment objectives and policies that constitute its principal portfolio emphasis that have not been approved by shareholders, except that the Fund may now enter into swap transactions, including credit default, total return, index and interest rate swap agreements, as well as options thereon; (ii) no material changes to the Fund's principal risks, (iii) no changes to the persons primarily responsible for day-to-day management of the Fund; and (iv) no changes to the Fund's charter or by-laws that would delay or prevent a change of control that have not been approved by shareholders.
Investment Objectives and Policies
The Fund's investment objective is to seek to provide current income exempt from regular federal income tax, consistent with the preservation of capital. The Fund's investment objective is non-fundamental and may be changed on 60 days' notice to shareholders.
The Fund seeks to achieve its investment objective by investing under normal circumstances, substantially all (at least 80%) of its net assets in “Municipal Obligations.” “Municipal Obligations” are debt obligations issued by or on behalf of a state or territory or its agencies, instrumentalities, municipalities and political subdivisions, the interest payable on which is, in the opinion of bond counsel, excludable from gross income for purposes of federal income taxation (except, in certain instances, the alternative minimum tax, depending upon the shareholder’s tax status). The Fund's policy to invest 80% of its net assets in Municipal Obligations is fundamental and may not be changed without approval of the holders of a majority of the outstanding shares of common stock and Preferred Shares voting together as a single class, and of the holders of a majority of the outstanding Preferred Shares voting as a separate class. The Fund may invest without limitation in securities that generate interest that is subject to federal alternative minimum tax. The Fund may invest without limitation in uninsured, “investment grade” Municipal Obligations. “Investment grade” means that, at the time of investment, a Municipal Obligation has a credit rating of at least Baa by Moody’s Investor Service, Inc (“Moody’s”) or BBB by Standard & Poor’s Financial Services LLC (“S&P”), or is unrated but judged by the Investment Manager, to be of comparable quality. 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. In the event that a
security receives different ratings from different nationally recognized statistical rating organizations ("NRSROs"), the Adviser will treat the security as being rated in the highest rating category received from an NRSRO.
The Investment Manager analyzes economic and market conditions, seeking to identify the securities or market sectors that the Investment Manager thinks are the best investments for the Fund. The Fund generally invests in debt obligations issued by state and local governments and their political subdivisions, agencies, authorities, and instrumentalities that are exempt from federal income tax. The Fund may also invest in debt obligations issued by or for the District of Columbia, and its political subdivisions, agencies, authorities, and instrumentalities or territories and possessions of the United States that are exempt from federal income tax.
The Fund will generally invest in securities for income rather than seeking capital appreciation through active trading. However, the Fund may sell securities for a variety of reasons, such as to reinvest the proceeds in higher yielding securities, to eliminate investments not consistent with the preservation of capital, to fund tender offers, or to address a weakening credit situation.
The Fund invests its assets in securities with maturities of various lengths, depending on market conditions, but will have a dollar-weighted average effective maturity of between between 15 and 30 years. The Investment Manager will adjust the average maturity of the bonds in the Fund’s portfolio to attempt to provide a current tax-exempt income, consistent with preservation of capital. The Fund may focus its investments in certain types of bonds or in a certain segment of the municipal bond market when the supply of bonds in other sectors do not suit its investment needs. The Investment Manager may also consider the most material potential ESG (Environmental, Social and Governance) risks and opportunities impacting issuers, where relevant. As ESG information is just one investment consideration, ESG considerations generally are not solely determinative in any investment decision made by the Investment Manager.
The Fund may invest without limitation in general obligation bonds in the top four quality grades or bonds that are unrated, but which the Investment Manager determines to be of equal quality. The Fund may invest without limitation in revenue bonds in the top four quality grades or bonds that are unrated, but which the Investment Manager determines to be of equal quality.
The Fund may invest without limitation in insured Municipal Obligations. In addition, insurance is available on uninsured bonds and the Fund may purchase such insurance directly. The Investment Manager will generally do so only if it believes that purchasing and insuring a Municipal Obligation provides an investment opportunity

at least comparable to owning other available insured Municipal Obligations.
Private activity or private placement bonds are municipal bond issues whose proceeds are used to finance certain nongovernment activities, including some types of industrial revenue bonds such as privately owned sports and convention facilities. The Tax Reform Act of 1986 subjects interest income from these bonds to the federal alternative minimum tax and makes the tax-exempt status of certain bonds dependent on the issuer’s compliance with specific requirements after the bonds are issued. As described above, the Fund may invest without limitation in securities that generate interest that is subject to federal alternative minimum tax. This means that a portion of the Fund’s distributions could be subject to the federal alternative minimum tax that applies to certain taxpayers. The Fund may invest without limit in advance refunded bonds.
The Fund may invest without limitation in high-quality, short-term tax-free instruments.
The Fund may invest in privately placed securities, including those that are eligible for resale only among certain institutional buyers without registration, commonly known as “Rule 144A Securities.” Restricted securities that are determined to be illiquid may not exceed the Fund’s 15% limit on investments in illiquid securities.
The Fund may invest without limitation in municipal lease obligations, primarily through certificates of participation rated in the top four quality grades by S&P or another nationally recognized statistical rating agency. As with the Fund’s other investments, the Investment Manager expects that investments in municipal lease obligations will be exempt from regular federal income taxes. The Fund will rely on the opinion of the bond issuer’s counsel for a determination of the bond’s tax-exempt status.
The Fund may invest in zero coupon bonds.
Credit quality restrictions for the Fund apply only at the time of purchase. The Fund may continue to hold a security whose quality rating has been lowered or, in the case of an unrated bond, after the Manager has changed its assessment of its credit quality.
The Fund may buy or sell securities on a when-issued or delayed-delivery basis; that is, paying for securities before delivery or taking delivery at a later date. The Fund will designate cash or securities in amounts sufficient to cover its obligations, and will value the designated assets daily.
Where the Investment Manager feels there is a limited supply of appropriate investments, the Fund may invest more than 25% of its total assets in Municipal Obligations relating to similar types of projects or with other similar economic, business, or political charac- teristics (such as bonds of housing finance agencies or healthcare
facilities). The Fund will not, however, invest more than 25% of its total assets in bonds issued for companies in the same industry.
The Fund currently uses leverage as part of its investment strategy through the issuance of preferred shares, and may use leverage to the maximum extent permitted by the 1940 Act. The Fund uses leverage because its Investment Manager believes that, over time, leveraging may provide opportunities for additional income and total return for common shareholders. There is no assurance that the Fund’s leveraging strategy will be successful. Leverage involves special risks. See “Risk Factors – Leverage Risk”.
Although it has no present intention to do so, the Fund reserves the right to borrow money from banks or other financial institutions, or issue debt securities, in the future if it believes that market conditions would be conducive to the successful implementation of a leveraging strategy through borrowing money or issuing debt securities. Any such leveraging will not be fully achieved until the proceeds resulting from the use of leverage have been invested in accordance with the Fund’s investment objective and policies.
In addition to leverage for investment purposes, the Fund may also borrow money from banks as a temporary measure for extraordinary or emergency purposes, including the payment of distributions and the settlement of securities transactions which otherwise might require untimely dispositions of Fund investments.
The Fund may enter into swap transactions, including credit default, total return, index and interest rate swap agreements, as well as options thereon, and may purchase or sell interest rate caps, floors and collars. A swap is a derivative in the form of an agreement to exchange the return (or differentials in the rates of return) earned or realized on particular predetermined investments or instruments. The payment obligations are calculated by reference to an agreed upon notional amount or amounts. The Fund will usually enter into swaps for which obligations are calculated on a net basis, i.e., on each payment date under the swap the two payment streams are netted out in a cash settlement, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. The Fund may enter into over-the-counter derivatives transactions (swaps, caps, floors and puts).
The risk of investing in swaps or other derivatives instruments include leverage, liquidity, interest rate, market, counterparty (including credit), operational, legal and management risks, and valuation complexity. Changes in the value of a derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and the Fund could lose more than the initial amount invested. Changes in the value of a derivative may also create margin delivery or settlement payment obligations for the Fund. The Fund’s use of derivatives or other similar investments may result in losses to the Fund, a reduction in the Fund’s returns and/or

abrdn National Municipal Income Fund | 33

Additional Information Regarding the Fund (Unaudited) (continued)

increased volatility. Swaps generally do not involve the delivery of securities, other underlying assets or principal. Accordingly, the risk of loss with respect to swaps is limited to the net amount of payments that the Fund is contractually obligated to make. However, because some swap agreements have a leverage component, adverse changes in the value or level of the underlying asset, reference rate, or index can result in a loss substantially greater than the amount invested in the swap itself. If the other party to a swap defaults, the Fund's risk of loss generally consists of the net amount of payments that the Fund is contractually entitled to receive.
The Fund may write (sell) and purchase put and call swap options. A swap option, or swaption, is a contract that gives a counterparty the right (but not the obligation) to enter into a new swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, at some designated future time on specified terms. The Fund may engage in swaptions for hedging purposes, to manage and mitigate credit and interest rate risks and to gain exposure to credit obligations. The use of swaptions involves risks, including, among others, (i) changes in the market value of securities held by the Fund, and of swaptions relating to those securities may not be proportionate, (ii) there may not be a liquid market to sell a swaption, which could result in difficulty closing a position, (iii) swaptions can magnify the extent of losses incurred due to changes in the market value of the securities to which they relate and (iv) counterparty risk.
It is possible that government regulation of various types of derivative instruments, including swap agreements, may limit or prevent the Fund from using such instruments as part of its investment strategy, which could negatively impact the Fund.
In response to unfavorable market conditions, the Fund may invest in taxable instruments for temporary defensive purposes. These could include obligations of the US government, its agencies and instrumentalities, commercial paper, cash, certificates of deposit of domestic banks, repurchase agreements, reverse repurchase agreements, other cash equivalents, and other debt instruments. These investments may not be consistent with the Fund’s investment objective. To the extent that the Fund holds such investments, it may be unable to achieve its investment objective.
Risk Factors
Investing in any closed-end fund involves the risk that you may lose part or all of the money you invest. Over time, the value of your investment in the Fund will increase and decrease according to changes in the value of the securities in the Fund’s portfolio. An investment in the Fund may not be appropriate for all investors. The Fund’s principal risks include:
Investment and Market Risk
An investment in the Fund's Shares is subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in Shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other market investments, may move up or down, sometimes rapidly and unpredictably, and these fluctuations are likely to have a greater impact on the value of the Shares during periods in which the Fund utilizes a leveraged capital structure. If the global economy deteriorates, the ability of issuers of the corporate fixed-income securities and other securities in which the Fund invests to service their obligations could be materially and adversely affected. The value of the securities in which the Fund invests will affect the value of the Shares. Your Shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.
Management Risk
The Fund's ability to achieve its investment objective is directly related to the Investment Manager’s investment strategies for the Fund. The value of your investment in the Fund's common shares may vary with the effectiveness of the research and analysis conducted by the Investment Manager and its ability to identify and take advantage of attractive investment opportunities. If the investment strategies of the Investment Manager do not produce the expected results, the value of your investment could be diminished or even lost entirely, and the Fund could underperform the market or other funds with similar investment objectives. Additionally, there can be no assurance that all of the personnel of the Investment Manager will continue to be associated with the Investment Manager for any length of time. The loss of the services of one or more key employees of the Investment Manager could have an adverse impact on the Fund's ability to realize its investment objective.
Debt Securities Risk
The principal risks involved with investments in debt securities include interest rate risk, credit risk and pre-payment risk. Interest rate risk refers to the likely decline in the value as interest rates rise. Generally, longer-term securities are more susceptible to changes in value as a result of interest-rate changes than are shorter-term securities. Credit risk refers to the risk that an issuer of a security may default with respect to the payment of principal and interest. Credit risk associated with a particular issuer may be affected by the actual or perceived financial condition or the credit rating of the issuer, the issuer’s performance and profitability, perceptions of the issuer in the market place, and government regulations impacting the industry in which the issuer operates. Pre-payment risk refers to the risk that debt obligations are prepaid ahead of schedule. In this event, the proceeds from the prepaid securities would likely be reinvested by the Fund in

34 | abrdn National Municipal Income Fund

Additional Information Regarding the Fund (Unaudited) (continued)

securities bearing a lower interest rate. Pre-payment rates usually increase when interest rates are falling. Lower-rated securities are more likely to react to developments affecting these risks than are more highly rated securities. The lower a security is rated, the more it is considered to be a speculative or risky investment.
Municipal Securities Risk
Municipal securities are subject to various risks, including the inability of the issuer to repay the obligation, the relative lack of information about certain issuers of municipal securities, and the possibility of future legislative changes which could affect the market for and value of municipal securities. Additional risks include:
Municipal Bond Tax Risk - Investments in municipal securities rely on the opinion of the issuer’s bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable, and the Fund’s dividends with respect to that bond might be subject to federal income tax. Changes in tax laws or adverse determinations by the Internal Revenue Service may make the income from some municipal obligations taxable. From time to time, the U.S. Government and the U.S. Congress consider changes in federal tax law that could limit or eliminate the federal tax exemption for municipal bond income, which would in effect reduce the income received by shareholders from the Fund by increasing taxes on that income. In such event, the net asset value of the Fund investing in municipal bonds could also decline as yields on municipal bonds, which are typically lower than those on taxable bonds, would be expected to increase to approximately the yield of comparable taxable bonds.
Municipal Market Volatility and Illiquidity Risk - The municipal bond market can be susceptible to unusual volatility, particularly for lower-rated and unrated securities. Liquidity can be reduced unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices without the sale significantly changing the market value of the bonds. If the Fund needed to sell large blocks of bonds to raise cash, those sales could further reduce the bonds’ prices.
Municipal Sector Risk - While the Fund may not invest more than 25% of its total assets in the securities of any industry, certain types of municipal securities (such as general obligation, general appropriation, special assessment and special tax bonds) are not considered a part of any “industry” for purposes of this industry concentration policy. Therefore, the Fund may invest more than 25% of its total assets in these types of municipal securities. These types of municipal securities may finance, or pay interest from the revenues of,
projects that tend to be impacted in the same way by economic, business or political developments which would increase credit risk. For example, legislation on the financing of a project or a declining economic need for the project would likely affect all similar projects.
General Obligation Bonds Risks - The full faith, credit and taxing power of the municipality that issues a general obligation bond secures payment of interest and repayment of principal. Timely payments depend on the issuer’s credit quality, ability to raise tax revenues and ability to maintain an adequate tax base.
Revenue Bonds Risks - Payments of interest and principal on revenue bonds are made only from the revenues generated by a particular facility, class of facilities or the proceeds of a special tax or other revenue source. These payments depend on the money earned by the particular facility or class of facilities, or the amount of revenues derived from another source.
Private Activity Bonds Risks - Municipalities and other public authorities issue private activity bonds to finance development of industrial facilities for use by a private enterprise. The private enterprise pays the principal and interest on the bond, and the issuer does not pledge its full faith, credit and taxing power for repayment. If the private enterprise defaults on its payments, the Fund may not receive any income or get its principal back from the investment.
Moral Obligation Bonds Risks - Moral obligation bonds are generally issued by special purpose public authorities of a state or municipality. If the issuer is unable to meet its obligations, repayment of these bonds becomes a moral commitment, but not a legal obligation, of the state or municipality. Municipal Notes Risks – Municipal notes are shorter term municipal debt obligations. They may provide interim financing in anticipation of, and are secured by, tax collection, bond sales or revenue receipts. If there is a shortfall in the anticipated proceeds, municipal notes may not be fully repaid and the Fund may lose money.
Municipal Lease Obligations Risks - In a municipal lease obligation, the issuer agrees to make payments when due on the lease obligation. The issuer will generally appropriate municipal funds for that purpose, but is not obligated to do so. Although the issuer does not pledge its unlimited taxing power for payment of the lease obligation, the lease obligation is secured by the leased property. However, if the issuer does not fulfill its payment obligation it may be difficult to sell the property and the proceeds of a sale may not cover the Fund’s loss.
State-Specific Risk - The Fund may from time to time invest a substantial amount of its total assets in municipal securities of issuers in one or more states and, therefore, is subject to the risk that the economies of the states in which it invests, and the revenues supporting the municipal securities, may decline. Investing a substantial amount of its total assets in one or more states means

abrdn National Municipal Income Fund | 35

Additional Information Regarding the Fund (Unaudited) (continued)

that the Fund is more susceptible to the economic, market, political, regulatory or other occurrences that affect that State's issuers to pay interest or repay principal. To the extent a state’s government revenues rely heavily on certain earners, revenues are likely to be more volatile and to be adversely affected if the number of such earners (or their recognized income within a particular period of time) decreases. Provisions of state constitutions and statutes that limit the taxing and spending authority of governmental entities may impair the ability of state issuers to pay principal and/or interest on their obligations. Political and economic developments, constitutional amendments, legislative measures, executive orders, administrative regulations, litigation and voter initiatives as well as environmental events, natural disasters, pandemics, epidemics or social unrest affecting a specific state could have an adverse effect on the debt obligations of such state’s issuers. The particular states in which the Fund may focus its investments may change over time and the Fund may alter its focus at inopportune times. As of September 30, 2025, the Fund held 10% or more of its assets in each of the following States or territories: New York (more than 20% of the Fund’s assets), California, Florida, Illinois, Texas and Wisconsin.

• | New York State-Specific Risk - Certain issuers of New York municipal bonds have experienced serious financial difficulties in the past and reoccurrence of these difficulties may impair the ability of certain New York issuers to pay principal or interest on their obligations, particularly given large budget deficits that have been identified and may continue. While New York’s economy is broad, it does have major concentrations in certain industries, such as financial services. Adverse conditions in one or more of these industries could impair the ability of issuers of New York municipal securities to pay principal or interest on their obligations. The financial health of New York City affects that of the state, and when New York City experiences financial difficulty it may have an adverse affect on New York municipal bonds held by such Fund. The growth rate of New York has at times been somewhat slower than the nation overall.

• | California State-Specific Risk - Certain issuers of California municipal bonds have experienced serious financial difficulties in the past and reoccurrence of these difficulties may impair the ability of certain California issuers to pay principal or interest on their obligations. While California’s economy is broad, it does have major concentrations in advanced technology, aerospace and defense-related manufacturing, trade, entertainment, real estate and financial services. Adverse conditions in one or more of these industries could impair the ability of issuers of California municipal securities to pay principal or interest on their obligations.

• | Florida State-Specific Risk - Florida's economy is largely composed of services, trade, construction, agriculture, manufacturing and tourism. The exposure to these industries, particularly tourism, leaves Florida vulnerable to an economic slowdown associated with business cycles. Adverse conditions in one or more of these industries could impair the ability of issuers of Florida municipal

| securities to pay principal or interest on their obligations. When compared with other states, Florida has a proportionately greater retirement age population, and property income (dividends, interest and rent) and transfer payments (including social security and pension benefits) are a relatively more important source of income.

• | Illinois State-Specific Risk - Certain issuers of Illinois municipal bonds have experienced serious financial difficulties in the past and reoccurrence of these difficulties may impair the ability of certain Illinois issuers to pay principal or interest on their obligations. Illinois’ economy has major concentrations in certain industries and may be sensitive to economic problems affecting those industries. In addition, Illinois' government revenues tend to rely heavily on certain earners and therefore, are likely to be more volatile and to be adversely affected if the number of such earners (or their recognized income within a particular period of time) decreases.

• | Texas State-Specific Risk - Texas’ economy relies to a significant extent on certain key industries, such as the oil and gas industry (including drilling, production and refining), chemicals production, technology and telecommunications equipment manufacturing and international trade. Adverse conditions in one or more of these industries could impair the ability of issuers of Texas municipal securities to pay principal or interest on their obligations.

• | Wisconsin State-Specific Risk - Wisconsin's economy is largely composed of the manufacturing and agriculture industries. Adverse conditions in one or more of these industries could impair the ability of issuers of Wisconsin municipal securities to pay principal or interest on their obligations.

Market Events Risk
The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to changes in general market conditions, overall economic trends or events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes, armed conflicts or other factors, political events within the U.S. and abroad, such as changes in the U.S. presidential administration and Congress, investor sentiment and other factors that may or may not be related to the issuer of the security or other asset. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, imposition of sanctions and other measures, trading and tariff arrangements, actual or threatened war or armed conflicts, terrorism, social unrest, natural or environmental disasters and other circumstances in one country or region could have profound impacts on global economies or markets. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the Fund's investments may be negatively affected. In addition, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) or similar issues could reduce consumer demand or economic output, result in

36 | abrdn National Municipal Income Fund

Additional Information Regarding the Fund (Unaudited) (continued)

market closures, travel restrictions or quarantines, and generally have a significant impact on the world economy, which in turn could adversely affect the Fund's investments. The impact of the recent U.S. elections on such policies remains uncertain and policies supported by the new administration (or the reversal of policies supported by the previous administration) could impact U.S. interest rates or inflation or otherwise impact the Fund.
Interest Rate Risk
The Fund’s fixed income investments are subject to interest rate risk, which generally causes the value of a fixed income portfolio to decrease when interest rates rise resulting in a decrease in the Fund’s net assets. For example, if interest rates increase by 1%, assuming a current portfolio duration of 7 years, and all other factors being equal, the value of the Fund’s investments would be expected to decrease by 7%.
Interest rate fluctuations tend to have a greater impact on fixed income-securities with a greater time to maturity and/or lower coupon. The fund with a longer average portfolio duration will be more sensitive to changes in interest rates than the fund with a shorter average portfolio duration. In periods of market volatility, the market values of fixed income securities may be more sensitive to changes in interest rates. The Fund may be subject to increased interest rate risk. Such risk is heightened in market environments where interest rates are changing, notably when rates are rising.
High Yield Bonds and Other Lower-rated Securities Risk
The Fund’s 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.
Sector Risk
To the extent that the Fund has a significant portion of its assets invested in securities of companies conducting business in a broadly related group of industries within an economic sector, the Fund may be more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.
Geographic Focus Risk
The Fund’s performance could be more volatile than that of a more geographically diversified fund and could be significantly impacted as a result of the Fund investing a large percentage of its assets in issuers
located in a single country, a small number of countries, or a particular geographic region. Also, the Fund’s performance may be more closely tied to the market, currency, economic, political, or regulatory conditions in those countries or that region.
Leverage Risk
Leverage creates the following types of risks for shareholders, among other types: i) the likelihood of greater volatility of NAV and market price of common shares because changes in value of the Fund's portfolio (including changes in the value of any interest rate swap, if applicable) are borne entirely by the common shareholders; ii) the possibility either that share income will fall if the interest rate on any borrowings or the dividend rate on any preferred shares issued rises, or that share income and distributions will fluctuate because the interest rate on any borrowings or the dividend rate on any preferred shares issued varies; iii) if the Fund leverages through issuing preferred shares or borrowings, the Fund may not be permitted to declare dividends or other distributions with respect to its common shares or purchase its capital stock, unless at the time thereof the Fund meets certain asset coverage requirements.
With respect to asset coverage for preferred shares, under the 1940 Act, the Fund is not permitted to issue preferred shares unless immediately after such issuance the value of the Fund's total net assets (as defined below) is at least 200% of the liquidation value of the outstanding preferred shares and the newly issued preferred shares plus the aggregate amount of any senior securities of the Fund representing indebtedness (i.e., such liquidation value plus the aggregate amount of senior securities representing indebtedness may not exceed 50% of the Fund's total net assets). In addition, the Fund is not permitted to declare any cash dividend or other distribution on its Common Shares unless, at the time of such declaration, the value of the Fund's total net assets (determined after deducting the amount of such dividend or other distribution) satisfies the above-referenced 200% coverage requirement.
The 1940 Act generally prohibits the Fund from engaging in most forms of leverage representing indebtedness other than preferred shares unless immediately after such incurrence the Fund's total assets less all liabilities and indebtedness not represented by senior securities (for these purposes, "total net assets") is at least 300% of the aggregate senior securities representing indebtedness (i.e., the use of leverage through senior securities representing indebtedness may not exceed 33 1/3% of the Fund's total net assets (including the proceeds from leverage)). Additionally, under the 1940 Act, the Fund generally may not declare any dividend or other distribution upon any class of its capital shares, or purchase any such capital shares, unless at the time of such declaration or purchase, this asset coverage test is satisfied.

abrdn National Municipal Income Fund | 37

Additional Information Regarding the Fund (Unaudited) (continued)

Leverage involves certain additional risks, including the risk that the cost of leverage may exceed the return earned by the Fund on the proceeds of such leverage. The use of leverage will increase the volatility of changes in the Fund's NAV, market price and distributions. In the event of a general market decline in the value of assets in which the Fund invests, the effect of that decline will be magnified in the Fund because of the additional assets purchased with the proceeds of the leverage.
In addition, funds borrowed pursuant a credit facility may constitute a substantial lien and burden by reason of their prior claim against the income of the Fund and against the net assets of the Fund in liquidation. In the event of an event of default under a loan facility, lenders may have the right to cause a liquidation of the collateral (i.e., sell portfolio securities and other assets of the Fund) and, if any such default is not cured, the lenders may be able to control the liquidation as well. A leverage facility agreement may include covenants that impose on the Fund asset coverage requirements, Fund composition requirements and limits on certain investments, such as illiquid investments or derivatives, which are more stringent than those imposed on the Fund by the 1940 Act. However, because the Fund's use of leverage is expected to be relatively modest and flexible in approach, the Investment Manager currently does not believe that these restrictions would significantly impact its management of the Fund.
The Investment Manager in its best judgment nevertheless may determine to maintain the Fund's leveraged position if it deems such action to be appropriate in the circumstances. During periods in which the Fund is using leverage, the fees paid to the Investment Manager for investment advisory services will be higher than if the Fund did not use leverage because the fees paid will be calculated on the basis of the Fund's total assets, including proceeds from borrowings, which may create an incentive to leverage the Fund.
Alternative Minimum Tax Risk
To the extent the Fund invests in bonds whose income is subject to the alternative minimum tax, that portion of the Fund’s distributions would be taxable for shareholders who are subject to this tax.
Inflation Risk
Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. To the extent that inflation occurs, it will reduce the real value of dividends paid by the Fund and the Fund’s Common Shares. Most emerging market countries, in particular, have experienced substantial, and in some periods extremely high and volatile, rates of inflation. Inflation and rapid fluctuations in inflation rates have had and may continue to have very negative effects on the economies and securities markets globally. In an attempt to control
inflation, wage and price controls have been imposed at times in certain countries.
Cybersecurity Risk
Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data (including private shareholder information), or proprietary information, or cause each Fund, the Investment Manager and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or lose operational functionality. In addition, work-from-home arrangements by the Fund, the Investment Manager or their service providers could increase all of the above risks, create additional data and information accessibility concerns, and make the Fund, the Investment Manager or their service providers susceptible to operational disruptions, any of which could adversely impact their operations. Furthermore, the Fund may be an appealing target for cybersecurity threats such as hackers and malware.
Market Discount Risk
Shares of closed-end investment companies frequently trade at a discount from NAV. Continued development of alternative vehicles for investing in essential asset companies may contribute to reducing or eliminating any premium or may result in the Fund's common shares trading at a discount. The risk that the Fund's common shares may trade at a discount is separate from the risk of a decline in the Fund's NAV as a result of investment activities.
Whether shareholders will realize a gain or loss for federal income tax purposes upon the sale of their common shares depends upon whether the market value of the common shares at the time of sale is above or below the shareholder's basis in such common shares, taking into account transaction costs, and it is not directly dependent upon the Fund's NAV. Because the market price of the Fund's common shares will be determined by factors such as the relative demand for and supply of the shares in the market, general market conditions and other factors beyond the Fund's control, the Fund cannot predict whether its common shares will trade at, below or above the NAV, or at, below or above the public offering price for the Fund's common shares.
Distribution Rate Risk
It is the Fund's current policy to pay distributions on a monthly basis. If the Fund's investments do not generate sufficient income, the Fund may be required to liquidate a portion of its portfolio to fund these distributions, and therefore a portion or all of such distributions may represent a reduction of the shareholders' principal investment. Such liquidation might be at a time when independent investment judgment would not dictate such action, increasing the Fund's overall

38 | abrdn National Municipal Income Fund

Additional Information Regarding the Fund (Unaudited) (continued)

portfolio turnover (and related transaction costs) and making it more difficult for the Fund to achieve its investment objective.
Valuation Risk
The price the Fund could receive upon the sale of any particular portfolio investment may differ from the Fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair valuation methodology or a price provided by an independent pricing service. As a result, the price received upon the sale of an investment may be less than the value ascribed by the Fund, and the Fund could realize a greater than expected loss or lesser than expected gain upon the sale of the investment.
Pricing services that value fixed-income securities generally utilize a range of market-based and security-specific inputs and assumptions, as well as considerations about general market conditions, to establish a price. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size and the strategies employed by the Investment Manager generally trade in round lot sizes. In certain circumstances, fixed income securities may be held or transactions may be conducted in smaller, odd lot sizes. Odd lots may trade at lower or, occasionally, higher prices than institutional round lots. The Fund’s ability to value its investments may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.
Derivatives Risk (including Swaps):
The risk of investing in swaps (or other derivatives instruments) include leverage, liquidity, interest rate, market, counterparty (including credit), operational, legal and management risks, and valuation complexity. Changes in the value of a derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and the Fund could lose more than the initial amount invested. Changes in the value of a derivative may also create margin delivery or settlement payment obligations for the Fund. The Fund’s use of derivatives or other similar investments may result in losses to the Fund, a reduction in the Fund’s returns and/or increased volatility. Swaps generally do not involve the delivery of securities, other underlying assets or principal. Accordingly, the risk of loss with respect to swaps is limited to the net amount of payments that the Fund is contractually obligated to make. However, because some swap agreements have a leverage component, adverse changes in the value or level of the underlying asset, reference rate, or index can result in a loss substantially greater than the amount invested in the swap itself. If the other party to a swap defaults, the Fund's risk of loss generally consists of the net amount of payments that the Fund is contractually entitled to receive.
The Fund may write (sell) and purchase put and call swap options. A swap option, or swaption, is a contract that gives a counterparty the right (but not the obligation) to enter into a new swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, at some designated future time on specified terms. The Fund may engage in swaptions for hedging purposes, to manage and mitigate credit and interest rate risks and to gain exposure to credit obligations. The use of swaptions involves risks, including, among others, (i) changes in the market value of securities held by the Fund, and of swaptions relating to those securities may not be proportionate, (ii) there may not be a liquid market to sell a swaption, which could result in difficulty closing a position, (iii) swaptions can magnify the extent of losses incurred due to changes in the market value of the securities to which they relate and (iv) counterparty risk.
It is possible that government regulation of various types of derivative instruments, including swap agreements, may limit or prevent the Fund from using such instruments as part of its investment strategy, which could negatively impact the Fund.
Potential Conflicts of Interest Risk
The portfolio managers’ management of “other accounts” may give rise to potential conflicts of interest in connection with their management of the Fund’s investments, on the one hand, and the investments of the other accounts, on the other. The other accounts may have the same investment objective as the Fund. Therefore, a potential conflict of interest may arise as a result of the identical investment objectives, whereby the portfolio manager could favor one account over another. However, the Investment Manager believes that these risks are mitigated by the fact that: (i) accounts with like investment strategies managed by a particular portfolio manager are generally managed in a similar fashion, subject to exceptions to account for particular investment restrictions or policies applicable only to certain accounts, differences in cash flows and account sizes, and similar factors; and (ii) portfolio manager personal trading is monitored to avoid potential conflicts. In addition, the Investment Manager has adopted trade allocation procedures that require equitable allocation of trade orders for a particular security among participating accounts.
In some cases, another account managed by the same portfolio manager may compensate the Investment Manager based on the performance of the portfolio held by that account. The existence of such a performance-based fee may create additional conflicts of interest for the portfolio manager in the allocation of management time, resources and investment opportunities.
Another potential conflict could include instances in which securities considered as investments for the Fund also may be appropriate for other investment accounts managed by the Investment Manager or its affiliates. Whenever decisions are made to buy or sell securities by

abrdn National Municipal Income Fund | 39

Additional Information Regarding the Fund (Unaudited) (continued)

the Fund and one or more of the other accounts simultaneously, the Investment Manager may aggregate the purchases and sales of the securities and will allocate the securities transactions in a manner that it believes to be equitable under the circumstances. As a result of the allocations, there may be instances where the Fund will not participate in a transaction that is allocated among other accounts. While these aggregation and allocation policies could have a detrimental effect on the price or amount of the securities available to the Fund from time to time, it is the opinion of the Investment Manager that the benefits from the policies outweigh any disadvantage that may arise from exposure to simultaneous transactions. The Trust has adopted policies that are designed to eliminate or minimize conflicts of interest, although there is no guarantee that procedures adopted under such policies will detect each and every situation in which a conflict arises.
From time to time, the Investment Manager may seed proprietary accounts for the purpose of evaluating a new investment strategy that eventually may be available to clients through one or more product structures. Such accounts also may serve the purpose of establishing a performance record for the strategy. The management by the Investment Manager of accounts with proprietary interests and nonproprietary client accounts may create an incentive to favor the proprietary accounts in the allocation of investment opportunities, and the timing and aggregation of investments. The Investment Manager's proprietary seed accounts may include long-short strategies, and certain client strategies may permit short sales. A conflict of interest arises if a security is sold short at the same time as a long position, and continuous short selling in a security may adversely affect the stock price of the same security held long in client accounts. The Investment Manager has adopted various policies to mitigate these conflicts.
In addition, the 1940 Act limits the Fund’s ability to enter into certain transactions with certain affiliates of the Investment Manager. As a result of these restrictions, the Fund may be prohibited from buying or selling any security directly from or to any portfolio company of the fund managed by the Investment Manager or one of its affiliates. Nonetheless, the Fund may under certain circumstances purchase any such portfolio company’s loans or securities in the secondary market, which could create a conflict for the Investment Manager between the interests of the Fund and the portfolio company, in that the ability of the Investment Manager to recommend actions in the best interest of the Fund might be impaired. The 1940 Act also prohibits certain “joint” transactions with certain of the Fund’s affiliates (which could include other funds managed by the Investment Manager), which could be deemed to include certain types of investments, or restructuring of investments, in the same portfolio company (whether at the same or different times). These
limitations may limit the scope of investment opportunities that would otherwise be available to the Fund.
Conflicts of interest may arise where the Fund and other funds or accounts managed or administered by the Investment Manager simultaneously hold securities representing different parts of the capital structure of a stressed or distressed issuer. In such circumstances, decisions made with respect to the securities held by one fund or account may cause (or have the potential to cause) harm to the different class of securities of the issuer held by other fund or account (including the Fund). For example, if such an issuer goes into bankruptcy or reorganization, becomes insolvent or otherwise experiences financial distress or is unable to meet its payment obligations or comply with covenants relating to credit obligations held by the Fund or by the other funds or accounts managed by the Investment Manager, such other funds or accounts may have an interest that conflicts with the interests of the Fund. If additional financing for such an issuer is necessary as a result of financial or other difficulties, it may not be in the best interests of the Fund to provide such additional financing, but if the other funds or accounts were to lose their respective investments as a result of such difficulties, the Investment Manager may have a conflict in recommending actions in the best interests of the Fund. In such situations, the Investment Manager will seek to act in the best interests of each of the funds and accounts (including the Fund) and will seek to resolve such conflicts in accordance with its compliance policies and procedures.
The Investment Manager or their respective members, officers, directors, employees, principals or affiliates may come into possession of material, non-public information. The possession of such information may limit the ability of the Fund to buy or sell a security or otherwise to participate in an investment opportunity. Situations may occur where the Fund could be disadvantaged because of the investment activities conducted by the Investment Manager for other clients, and the Investment Manager will not employ information barriers with regard to its operations on behalf of its registered and private funds, or other accounts. In certain circumstances, employees of the Investment Manager may serve as board members or in other capacities for portfolio or potential portfolio companies, which could restrict the Fund’s ability to trade in the securities of such companies.
Fundamental Investment Restrictions
The following are the fundamental investment limitations of the Fund. Investment limitations identified as fundamental may be changed only with the approval of the holders of a majority of the Fund's outstanding voting securities (which for this purpose and under the 1940 Act, means the lesser of (1) 67% of the voting shares present in person or by proxy at a meeting at which more than 50% of

40 | abrdn National Municipal Income Fund

Additional Information Regarding the Fund (Unaudited) (continued)

the outstanding voting shares are present in person or by proxy, or (2) more than 50% of the outstanding voting shares).
The Fund may not:

1. | make investments that will result in the concentration (as that term may be defined in the 1940 Act, any rule or order thereunder, or SEC staff interpretation thereof) of its investments in the securities of issuers primarily engaged in the same industry, provided that this restriction does not limit the Fund from investing in obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities, or in tax-exempt securities or certificates of deposit;

2. | borrow money or issue senior securities, except as the 1940 Act, any rule or order thereunder, or SEC staff interpretation thereof, may permit;

3. | underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933, as amended;

4. | purchase or sell real estate unless acquired as a result of ownership of securities or other instruments and provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein;

5. | purchase or sell physical commodities, unless acquired as a result of ownership of securities or other instruments and provided that this restriction does not prevent the Fund from engaging in transactions involving futures contracts and options thereon or investing in securities that are secured by physical commodities; and

6. | make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, loaning its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Effects of Leverage
The following table is furnished in response to requirements of the SEC. It is designed to, among other things, illustrate the effects of leverage through the use of senior securities, as that term is defined under Section 18 of the 1940 Act, on Common Share total return, assuming investment portfolio total returns (consisting of income and changes in the value of investments held in a Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. The table below reflects the Fund’s continued use of senior securities, Preferred Shares, the revolving
credit facility and reverse repurchase agreements, as applicable, as of September 30, 2025 as a percentage of total managed assets (including assets attributable to such leverage), the estimated annual effective Preferred Share dividend rate and interest expense rate payable by the Fund on such instruments (based on market conditions as of September 30, 2025), and the annual return that the Fund’s portfolio must experience (net of expenses) in order to cover such costs. The information below does not reflect the Fund’s use of certain other forms of economic leverage achieved through the use of other instruments or transactions not considered to be senior securities under the 1940 Act, such as covered reverse repurchase agreements, covered credit default swaps or other derivative instruments, if any.
The assumed investment portfolio returns in the table below are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. Your actual returns may be greater or less than those appearing below. In addition, actual borrowing expenses associated with borrowings used by the Fund may vary frequently and may be significantly higher or lower than the rate used for the example below.

Assumed annual returns on the Fund's portfolio (net of expenses) | (10%) | (5%) | 0% | 5% | 10%
Corresponding return of shareholder | (19.9%) | (11.4%) | (2.8%) | 5.8% | 14.3%

Based on estimated indebtedness of $99,000,000 (representing approximately 41.6% of the Fund's Managed Assets as of September 30, 2025), and a weighted average annual interest rate of 3.94% (interest rate on the preferred shares as of September 30, 2025), the Fund's investment portfolio at fair value would have to produce an annual return of approximately 1.64% to cover annual interest payments on the estimated debt.
Share total return is composed of two elements—the distributions paid by the Fund to holders of Shares (the amount of which is largely determined by the net investment income of the Fund after paying dividend payments on any preferred shares issued by the Fund and expenses on any forms of leverage outstanding) and gains or losses on the value of the securities and other instruments the Fund owns. As required by SEC rules, the table assumes that a Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0%, a Fund must assume that the income it receives on its investments is entirely offset by losses in the value of

abrdn National Municipal Income Fund | 41

Additional Information Regarding the Fund (Unaudited) (concluded)

those investments. This table reflects hypothetical performance of a Fund's portfolio and not the actual performance of the Fund's Shares, the value of which is determined by market forces and other factors.
Should the Fund elect to add additional leverage to its portfolio, any benefits of such additional leverage cannot be fully achieved until the proceeds resulting from the use of such leverage have been received
by the Fund and invested in accordance with the Fund's investment objective and policies. As noted above, the Fund's willingness to use additional leverage, and the extent to which leverage is used at any time, will depend on many factors, including, among other things, the Investment Manager's assessment of the yield curve environment, interest rate trends, market conditions and other factors.

42 | abrdn National Municipal Income Fund

Dividend Reinvestment and Optional Cash Purchase Plan (Unaudited)

The Fund intends to distribute to shareholders substantially all of its net investment income and to distribute any net realized capital gains at least annually. Net investment income for this purpose is income other than net realized long-term and short-term capital gains net of expenses. Pursuant to the Dividend Reinvestment and Optional Cash Purchase Plan (the “Plan”), shareholders whose shares of common stock are registered in their own names will be deemed to have elected to have all distributions automatically reinvested by Computershare Trust Company N.A. (the “Plan Agent”) in the Fund shares pursuant to the Plan, unless such shareholders elect to receive distributions in cash. Shareholders who elect to receive distributions in cash will receive such distributions paid by check in U.S. Dollars mailed directly to the shareholder by the Plan Agent, as dividend paying agent. In the case of shareholders such as banks, brokers or nominees that hold shares for others who are beneficial owners, the Plan Agent will administer the Plan on the basis of the number of shares certified from time to time by the shareholders as representing the total amount registered in such shareholders’ names and held for the account of beneficial owners that have not elected to receive distributions in cash. Investors that own shares registered in the name of a bank, broker or other nominee should consult with such nominee as to participation in the Plan through such nominee and may be required to have their shares registered in their own names in order to participate in the Plan. Please note that the Fund does not issue certificates so all shares will be registered in book entry form. The Plan Agent serves as agent for the shareholders in administering the Plan. If the Trustees of the Fund declare an income dividend or a capital gains distribution payable either in the Fund’s common stock or in cash, nonparticipants in the Plan will receive cash and participants in the Plan will receive common stock, to be issued by the Fund or purchased by the Plan Agent in the open market, as provided below. If the market price per share (plus expected per share fees) on the valuation date equals or exceeds NAV per share on that date, the Fund will issue new shares to participants at NAV; provided, however, that if the NAV is less than 95% of the market price on the valuation date, then such shares will be issued at 95% of the market price. The valuation date will be the payable date for such distribution or dividend or, if that date is not a trading day on the NYSE American, the immediately preceding trading date. If NAV exceeds the market price of Fund shares at such time, or if the Fund should declare an income dividend or capital gains distribution payable only in cash, the Plan Agent will, as agent for the participants, buy Fund shares in the open market, on the NYSE American or elsewhere, for the participants’ accounts on, or shortly after, the payment date. If, before the Plan Agent has completed its purchases, the market price exceeds the NAV of the Fund's share, the average per share purchase price paid by the Plan Agent may exceed the NAV of the Fund’s shares, resulting in the acquisition of fewer shares than if the distribution had been paid in shares issued by the Fund on the dividend payment date. Because of
the foregoing difficulty with respect to open-market purchases, the Plan provides that if the Plan Agent is unable to invest the full dividend amount in open-market purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Agent will cease making open-market purchases and will receive the uninvested portion of the dividend amount in newly issued shares at the close of business on the last purchase date.
Participants have the option of making additional cash payments of a minimum of $50 per investment (by check, one-time online bank debit or recurring automatic monthly ACH debit) to the Plan Agent for investment in the Fund’s common stock, with an annual maximum contribution of $250,000. The Plan Agent will wait up to three business days after receipt of a check or electronic funds transfer to ensure it receives good funds. Following confirmation of receipt of good funds, the Plan Agent will use all such funds received from participants to purchase Fund shares in the open market on the 25th day of each month or the next trading day if the 25th is not a trading day.
If the participant sets up recurring automatic monthly ACH debits, funds will be withdrawn from his or her U.S. bank account on the 20th of each month or the next business day if the 20th is not a banking business day and invested on the next investment date. The Plan Agent maintains all shareholder accounts in the Plan and furnishes written confirmations of all transactions in an account, including information needed by shareholders for personal and tax records. Shares in the account of each Plan participant will be held by the Plan Agent in the name of the participant, and each shareholder’s proxy will include those shares purchased pursuant to the Plan. There will be no brokerage charges with respect to common shares issued directly by the Fund. However, each participant will pay a per share fee of $0.02 incurred with respect to the Plan Agent’s open market purchases in connection with the reinvestment of dividends, capital gains distributions and voluntary cash payments made by the participant. Per share fees include any applicable brokerage commissions the Plan Agent is required to pay.
Participants also have the option of selling their shares through the Plan. The Plan supports two types of sales orders. Batch order sales are submitted on each market day and will be grouped with other sale requests to be sold. The price will be the average sale price obtained by Computershare’s broker, net of fees, for each batch order and will be sold generally within 2 business days of the request during regular open market hours. Please note that all written sales requests are always processed by Batch Order. ($10 and $0.12 per share). Market Order sales will sell at the next available trade. The shares are sold real time when they hit the market, however an available trade must be presented to complete this transaction. Market Order sales may only

Dividend Reinvestment and Optional Cash Purchase Plan (Unaudited) (concluded)

be requested by phone at 1-800-647-0584 or using Investor Center through www.computershare.com/buyaberdeen. ($25 and $0.12 per share).
The receipt of dividends and distributions under the Plan will not relieve participants of any income tax that may be payable on such dividends or distributions. The Fund or the Plan Agent may terminate the Plan as applied to any voluntary cash payments made and any dividend or distribution paid subsequent to notice of the termination sent to members of the Plan at least 30 days prior to the record date for such dividend or distribution. The Plan also may be amended by
the Fund or the Plan Agent, but (except when necessary or appropriate to comply with applicable law or the rules or policies of the Securities and Exchange Commission or any other regulatory authority) only by mailing a written notice at least 30 days prior to the effective date to the participants in the Plan. All correspondence concerning the Plan should be directed to the Plan Agent by phone at 1-800-647-0584, using Investor Center through www.computershare.com/buyaberdeen or in writing to Computershare Trust Company N.A., P.O.

Item 4. Principal Accountant Fees and Services.

(a) – (d) Below is a table reflecting the fee information requested in Items 4(a) through (d):

Fiscal Year Ended |  | (a) Audit Fees1 |  |  | (b) Audit-Related Fees2 |  |  | (c) Tax Fees3 |  |  | (d) All Other Fees4 |

1 “Audit Fees” are the aggregate fees billed for professional services for the audit of the Fund’s annual financial statements and services provided in connection with statutory and regulatory filings or engagements.

2 “Audit Related Fees” are the aggregate fees billed for assurance and related services reasonably related to the performance of the audit or review of financial statements that are not reported under “Audit Fees”. These fees include offerings related to the Fund’s common shares.

3 “Tax Fees” are the aggregate fees billed for professional services for tax advice, tax compliance, and tax planning. These fees include: federal and state income tax returns, review of excise tax distribution calculations and federal excise tax return.

4 “All Other Fees” are the aggregate fees billed for products and services other than “Audit Fees”, “Audit-Related Fees” and “Tax Fees”.

5 Pre-approval exception under Rule 2-01 of Regulation S-X. The pre-approval exception for services provided directly to the Fund waives the pre-approval requirement for services other than audit, review or attest services if: (A) the aggregate amount of all such services provided constitutes no more than 5% of the total amount of revenues paid by the Fund to its accountant during the fiscal year in which the services are provided; (B) the Fund did not recognize the services as non-audit services at the time of the engagement; and (C) the services are promptly brought to the Audit Committee’s attention, and the Committee (or its delegate) approves the services before the audit is completed.

(e)(1) | The Registrant’s Audit Committee (the “Committee”) has adopted a Charter that provides that the Committee shall annually select, retain or terminate, and recommend to the Independent Trustees for their ratification, the selection, retention or termination, the Registrant’s independent auditor and, in connection therewith, to evaluate the terms of the engagement (including compensation of the independent auditor) and the qualifications and independence of the independent auditor, including whether the independent auditor provides any consulting, auditing or tax services to the Registrant’s investment adviser (the “Adviser”) or any sub-adviser, and to receive the independent auditor’s specific representations as to their independence, delineating all relationships between the independent auditor and the Registrant, consistent with the PCAOB Rule 3526 or any other applicable auditing standard. PCAOB Rule 3526 requires that, at least annually, the auditor: (1) disclose to the Committee in writing all relationships between the auditor and its related entities and the Registrant and its related entities that in the auditor’s professional judgment may reasonably be thought to bear on independence; (2) confirm in the letter that, in its professional judgment, it is independent of the Registrant within the meaning of the Securities Acts administered by the SEC; and (3) discuss the auditor’s independence with the audit committee. The Committee is responsible for actively engaging in a dialogue with the independent auditor with respect to any disclosed relationships or services that may impact the objectivity and independence of the independent auditor and for taking, or recommending that the full Board take, appropriate action to oversee the independence of the independent auditor. The Committee Charter also provides that the Committee shall review in advance, and consider approval of, any and all proposals by Management or the Adviser that the Registrant, the Adviser or their affiliated persons, employ the independent auditor to render “permissible non-audit services” to the Registrant and to consider whether such services are consistent with the independent auditor’s independence. The Committee may delegate to one or more of its members (“Delegates”) authority to pre-approve permissible non-audit services to be provided to the Registrant. Any pre-approval determination of a Delegate shall be presented to the full Committee at its next meeting. The Committee shall communicate any pre-approval made by it or a Delegate to the Adviser, who will ensure that the appropriate disclosure is made in the Registrant’s periodic reports required by Section 30 of the Investment Company Act of 1940, as amended, and other documents as required under the federal securities laws.

(e)(2) | None of the services described in each of paragraphs (b) through (d) of this Item involved a waiver of the pre-approval requirement by the Audit Committee pursuant to Rule 2-01 (c)(7)(i)(C) of Regulation S-X.

(f) | Not applicable.

(g) | Non-Audit Fees

The following table shows the amount of fees that KPMG LLP billed during the Fund’s last two fiscal years for non-audit services to the Registrant, and to the Adviser, and any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund (“Affiliated Fund Service Provider”):

POTENTIAL CONFLICTS OF INTEREST

The Adviser and its affiliates (collectively referred to herein as “Aberdeen”) serve as investment advisers for multiple clients, including the Registrant and other investment companies registered under the 1940 Act and private funds (such clients are also referred to below as “accounts”). The portfolio managers’ management of “other accounts” may give rise to potential conflicts of interest in connection with their management of the Registrant’s investments, on the one hand, and the investments of the other accounts, on the other. The other accounts may have the same investment objective as the Registrant. Therefore, a potential conflict of interest may arise as a result of the identical investment objectives, whereby the portfolio manager could favor one account over another. However, the Adviser believes that these risks are mitigated by the fact that: (i) accounts with like investment strategies managed by a particular portfolio manager are generally managed in a similar fashion, subject to exceptions to account for particular investment restrictions or policies applicable only to certain accounts, differences in cash flows and account sizes, and similar factors; and (ii) portfolio manager personal trading is monitored to avoid potential conflicts. In addition, the Adviser has adopted trade allocation procedures that require equitable allocation of trade orders for a particular security among participating accounts.

In some cases, another account managed by the same portfolio manager may compensate Aberdeen based on the performance-based fees with qualified clients. The existence of such a performance-based fee may create additional conflicts of interest for the portfolio manager in the allocation of management time, resources and investment opportunities.

Another potential conflict could include instances in which securities considered as investments for the Registrant also may be appropriate for other investment accounts managed by the Adviser or its affiliates. Whenever decisions are made to buy or sell securities for the Registrant and one or more of the other accounts simultaneously, the Adviser may aggregate the purchases and sales of the securities and will allocate the securities transactions in a manner that it believes to be equitable under the circumstances. As a result of the allocations, there may be instances where the Registrant will not participate in a transaction that is allocated among other accounts. While these aggregation and allocation policies could have a detrimental effect on the price or amount of the securities available to the Registrant from time to time, it is the opinion of the Adviser that the benefits from the policies outweigh any disadvantage that may arise from exposure to simultaneous transactions. The Registrant has adopted policies that are designed to eliminate or minimize conflicts of interest, although there is no guarantee that procedures adopted under such policies will detect each and every situation in which a conflict arises.

With respect to non-discretionary model delivery accounts (including UMA accounts) and discretionary SMA accounts, abrdn Inc. will utilize a third party service provider to deliver model portfolio recommendations and model changes to the Sponsors. abrdn Inc. seeks to treat clients fairly and equitably over time, by delivering model changes to our service provider and investment instructions for our other discretionary accounts to our trading desk, simultaneously or approximately at the same time. The service provider will then deliver the model changes to each Sponsor on a when-traded, randomized full rotation schedule. All Sponsors will be included in the rotation schedule, including SMA and UMA.

UMA Sponsors will be responsible for determining how and whether to implement the model portfolio or model changes and implementation of any client specific investment restrictions. The Sponsors are solely responsible for determining the suitability of the model portfolio for each model delivery client, executing trades and seeking best execution for such clients.

As it relates to SMA accounts, abrdn Inc. will be responsible for managing the account on the basis of each client’s financial situation and objectives, the day to day investment decisions, best execution, accepting or rejecting client specific investment restrictions and performance. The SMA Sponsors will collect suitability information and will provide a summary questionnaire for our review and approval or rejection. For dual contract SMAs, abrdn Inc. will collect a suitability assessment from the client, along with the Sponsor suitability assessment. Our third party service provider will monitor client specific investment restrictions on a day to day basis. For SMA accounts, model trades will be traded by the Sponsor or may be executed through a “step-out transaction,”- or traded away- from the client’s Sponsor if doing so is consistent with Aberdeen’s obligation to obtain best execution. When placing trades through Sponsor Firms (instead of stepping them out), we will generally aggregate orders where it is possible and in the client’s best interests. In the event we are not comfortable that a Sponsor can obtain best execution for a specific security and trading away is infeasible, we may exclude the security from the model.

Trading costs are not covered by the Wrap Program fee and may result in additional costs to the client. In some instances, step-out trades are executed without any additional commission, mark-up, or mark-down, but in many instances, the executing broker-dealer may impose a commission or a mark-up or mark-down on the trade. Typically, the executing broker will embed the added costs into the price of the trade execution, making it difficult to determine and disclose the exact added cost to clients. In this instance, these additional trading costs will be reflected in the price received for the security, not as a separate commission, on trade confirmations or on account statements. In determining best execution for SMA accounts, abrdn Inc. takes into consideration that the client will not pay additional trading costs or commission if executing with the Sponsor.

While UMA accounts are invested in the same strategies as and may perform similarly to SMA accounts, there are expected to be performance differences between them. There will be performance dispersions between UMAs and other types of accounts because Aberdeen does not have discretion over trading and there may be client specific restrictions for SMA accounts.

Aberdeen may have already commenced trading for its discretionary client accounts before the model delivery accounts have executed Aberdeen’s recommendations. In this event, trades placed by the model delivery clients may be subject to price movements, particularly with large orders or where securities are thinly traded, that may result in model delivery clients receiving less favorable prices than our discretionary clients. Aberdeen has no discretion over transactions executed by model delivery clients and is unable to control the market impact of those transactions.

Timing delays or other operational factors associated with the implementation of trades may result in non-discretionary and model delivery clients receiving materially different prices relative to other client accounts. In addition, the constitution and weights of stocks within model portfolios may not always be exactly aligned with similar discretionary accounts. This may create performance dispersions within accounts with the same or similar investment mandate.

DESCRIPTION OF COMPENSATION STRUCTURE

Aberdeen’s remuneration policies are designed to support its business strategy as a leading international asset manager. The objective is to attract, retain and reward talented individuals for the delivery of sustained, superior returns for Aberdeen’s clients and shareholders. Aberdeen operates in a highly competitive international employment market, and aims to maintain its strong track record of success in developing and retaining talent.

Aberdeen’s policy is to recognize corporate and individual achievements each year through an appropriate annual bonus scheme. The bonus is a single, fully discretionary variable pay award. The aggregate value of awards in any year is dependent on the group’s overall performance and profitability. Consideration is also given to the levels of bonuses paid in the market. Individual awards, which are payable to all members of staff, are determined by a rigorous assessment of achievement against defined objectives.

The variable pay award is composed of a mixture of cash and a deferred award, the portion of which varies based on the size of the award. Deferred awards are by default Aberdeen Group plc shares, with an option to put up to 50% of the deferred award into funds managed by Aberdeen. Overall compensation packages are designed to be competitive relative to the investment management industry.

Base Salary

Aberdeen’s policy is to pay a fair salary commensurate with the individual’s role, responsibilities and experience, and having regard to the market rates being offered for similar roles in the asset management sector and other comparable companies. Any increase is generally to reflect inflation and is applied in a manner consistent with other Aberdeen employees; any other increases must be justified by reference to promotion or changes in responsibilities.

Annual Bonus

The Remuneration Committee determines the key performance indicators that will be applied in considering the overall size of the bonus pool. In line with practices amongst other asset management companies, individual bonuses are not subject to an absolute cap. However, the aggregate size of the bonus pool is dependent on the group’s overall performance and profitability. Consideration is also given to the levels of bonuses paid in the market. Individual awards are determined by a rigorous assessment of achievement against defined objectives, and are reviewed and approved by the Remuneration Committee.

Aberdeen has a deferral policy which is intended to assist in the retention of talent and to create additional alignment of executives’ interests with Aberdeen’s sustained performance and, in respect of the deferral into funds managed by Aberdeen, to align the interest of portfolio managers with our clients.

Staff performance is reviewed formally at least once a year. The review process evaluates the various aspects that the individual has contributed to Aberdeen, and specifically, in the case of portfolio managers, to the relevant investment team. Discretionary bonuses are based on client service, asset growth and the performance of the respective portfolio manager. Overall participation in team meetings, generation of original research ideas and contribution to presenting the team externally are also evaluated.

In the calculation of a portfolio management team’s bonus, Aberdeen takes into consideration investment matters (which include the performance of funds, adherence to the company investment process, and quality of company meetings) as well as more subjective issues such as team participation and effectiveness at client presentations through key performance indicator scorecards. To the extent performance is factored in, such performance is not judged against any specific benchmark and is evaluated over the period of a year - January to December. The pre- or after-tax performance of an individual account is not considered in the determination of a portfolio manager’s discretionary bonus; rather the review process evaluates the overall performance of the team for all of the accounts the team manages.

Portfolio manager performance on investment matters is judged over all of the accounts the portfolio manager contributes to and is documented in the appraisal process. A combination of the team’s and individual’s performance is considered and evaluated.

Although performance is not a substantial portion of a portfolio manager’s compensation, Aberdeen also recognizes that fund performance can often be driven by factors outside one’s control, such as (irrational) markets, and as such pays attention to the effort by portfolio managers to ensure integrity of our core process by sticking to disciplines and processes set, regardless of momentum and ‘hot’ themes. Short-terming is thus discouraged and trading-oriented managers will thus find it difficult to thrive in the Aberdeen environment. Additionally, if any of the aforementioned undue risks were to be taken by a portfolio manager, such trend would be identified via Aberdeen’s dynamic compliance monitoring system.

In rendering investment management services, the Adviser may use the resources of additional investment adviser subsidiaries of Aberdeen Group plc. These affiliates have entered into a memorandum of understanding (“MOU”) pursuant to which investment professionals from each affiliate may render portfolio management, research or trading services to Aberdeen clients. Each investment professional who renders portfolio management, research or trading services under a MOU or personnel sharing arrangement (“Participating Affiliate”) must comply with the provisions of the Advisers Act, the 1940 Act, the Securities Act of 1933, the Exchange Act, and the Employee Retirement Income Security Act of 1974, and the laws of states or countries in which the Adviser does business or has clients. No remuneration is paid by the Fund with respect to the MOU/personnel sharing arrangements.

| (1) | On September 11, 2024, the Fund publicly announced that the Board of Trustees had approved an open market share repurchase program (the “Program”). Under the terms of the Program, the Fund is permitted to repurchase up to 10% of its outstanding shares of common stock in the open market during any 12 month period as of September 30 of the prior year. The Program allows the Fund to purchase, in the open market, its outstanding common shares, with the amount and timing of any repurchase determined at the discretion of the Fund's investment adviser. Such purchases may be made opportunistically at certain discounts to NAV per share in the reasonable judgment of management based on historical discount levels and current market conditions.
