President’s Letter

Dear Stockholder,

I am pleased to present this semi-annual report for Neuberger Municipal Fund Inc. (the Fund) for the six months ended April 30, 2026 (the reporting period). The report includes a portfolio commentary, a listing of the Fund’s investments and its unaudited financial statements for the reporting period.

The Fund’s investment objective is to provide a high level of current income exempt from federal income tax. The Fund may invest in securities the interest on which is subject to the federal alternative minimum tax. We maintain a conservative investment philosophy and disciplined investment process in an effort to provide you with tax-exempt current income over the long term with less volatility and risk.

Thank you for your confidence in the Fund. We will continue to do our best to retain your trust in the years to come.

Sincerely,

Joseph V. Amato
President and CEO
Neuberger Municipal Fund Inc.

Neuberger Municipal Fund Inc. Portfolio Commentary (Unaudited)

Neuberger Municipal Fund Inc. generated a 1.55% total return on a net asset value (NAV) basis for the six months ended April 30, 2026 (the reporting period), versus a 0.72% return for its benchmark, the Bloomberg 10-Year Municipal Bond Index (the Index). (Fund performance on a market price basis is provided in the table immediately following this commentary.) The use of leverage (typically a performance enhancer in up markets and a detractor during market retreats) contributed positively to the Fund’s performance during the reporting period.

The investment-grade municipal (muni) bond market generated a positive return and modestly outperformed the taxable investment-grade bond market during the reporting period. All told, the Bloomberg Municipal Bond Index returned 1.29% for the reporting period, whereas the overall taxable bond market, as measured by the Bloomberg U.S. Aggregate Bond Index, returned 0.54%. The fixed income market was impacted by a number of factors, including resilient economic growth, "sticky" inflation, questions over future Federal Reserve (Fed) monetary policy, the impact from the Trump administration’s tariffs, and several geopolitical issues, including the war in Iran.

In terms of the Fund’s results, yield curve exposure produced mixed results. Having an overall longer duration than the Index was negative for relative results during a rising rate environment. On the upside, having a more barbelled structure was a positive factor relative to the Index, which was focused at 10 years. Credit allocation was also additive for returns, as credits rated BBB outperformed credits rated AAA in the investment grade space, and below investment grade credits generally outperformed higher rated securities. The Fund experienced negative contributions from select project financings within the nursing home, charter school and higher education sectors, as well as an overweight to a tobacco related financing. There were no significant changes to the Fund’s portfolio during the reporting period.

Looking ahead, we are optimistic about the muni market’s prospects. We have a constructive view on the economy and believe stimulus from the "One Big Beautiful Bill Act" and deregulation should create tailwinds. However, federal policies including potential Medicaid cuts could affect certain parts of the market. Active credit decisions and "what you don’t own" may end up driving return outcomes. We are expecting another record year of supply. As bond pickers, we love having more bonds to choose from and recognize that when supply is heavy, sometimes deals fall through the cracks. While we do not anticipate a market move of the magnitude of the "Liberation Day" selloff, there should be no shortage of events that could cause market shifts, albeit smaller ones. Changes at the Fed, midterm elections and geopolitics could all cause pockets of volatility and, in turn, present opportunities. In our view, it should be a market environment where active management will matter.

Sincerely,

James L. Iselin and S. Blake Miller
Portfolio Co-Managers

Listed closed-end funds, unlike open-end funds, are not continually offered. Generally, there is an initial public offering and, once issued, shares of common stock of closed-end funds are sold in the secondary market on a stock exchange.

The performance data quoted represent past performance and do not indicate future results. Current performance may be lower or higher than the performance data quoted. For current performance data, please visit www.neuberger.com/cef-performance.

The results shown in the table reflect the reinvestment of income dividends and other distributions, if any. The results do not reflect the effect of taxes a stockholder would pay on Fund distributions or on the sale of shares of the Fund's common stock.

The investment return and market price will fluctuate and shares of the Fund’s common stock may trade at prices above or below NAV. Shares of the Fund’s common stock, when sold, may be worth more or less than their original cost.

Returns would have been lower if Neuberger Berman Investment Advisers LLC ("NBIA") had not waived a portion of its investment management fees during certain of the periods shown. The waived fees are from prior years that are no longer disclosed in the Financial Highlights.

Endnotes (Unaudited)

1	A portion of the Fund’s income may be a tax preference item for purposes of the federal alternative minimum tax for certain stockholders.
2	Returns based on the NAV of the Fund.
3	Returns based on the market price of shares of the Fund’s common stock on the NYSE American.
4	The Bloomberg 10-Year Municipal Bond Index is the 10-year (8-12 years to maturity) component of the Bloomberg Municipal Bond Index. The Bloomberg Municipal Bond Index measures the investment grade, U.S. dollar-denominated, long-term, tax-exempt bond market and has four main sectors: state and local general obligation bonds, revenue bonds, insured bonds and prerefunded bonds. Please note that the index does not take into account any fees and expenses or any tax consequences of investing in the individual securities that it tracks and that individuals cannot invest directly in any index. Data about the performance of this index are prepared or obtained by NBIA and include reinvestment of all income dividends and other distributions, if any. The Fund may invest in securities not included in the above described index and generally does not invest in all securities included in the index.
