ITEM 1. REPORTS TO STOCKHOLDERS.

     IMPORTANT DISTRIBUTION NOTICE

for Shareholders of the Nuveen Dynamic Municipal Opportunity Fund (NDMO) Semiannual Shareholder Report for the period ending April 30, 2022

The Nuveen Dynamic Municipal Opportunity Fund (NDMO) seeks to offer attractive cash flow to its shareholders, by converting the expected long-term total return potential of the Fund’s portfolio of investments into regular monthly distributions. Following is a discussion of the Managed Distribution Policy the Fund uses to achieve this.

The Fund pays monthly common share distributions that seek to convert the Fund’s expected long-term total return potential into regular cash flow. As a result, the Fund’s regular common share distributions (presented $0.0765 per share) may be derived from a variety of sources, including:

• net investment income consisting of regular interest and dividends,

• realized capital gains or,

• possibly, returns of capital representing in certain cases unrealized capital appreciation.

Such distributions are sometimes referred to as “managed distributions.” The Fund seeks to establish a distribution rate that roughly corresponds to the Adviser’s projections of the total return that could reasonably be expected to be generated by the Fund over an extended period of time. The Adviser may consider many factors when making such projections, including, but not limited to, long-term historical returns for the asset classes in which the Fund invests. As portfolio and market conditions change, the distribution amount and distribution rate on the Common Shares under the Fund’s Managed Distribution Policy could change.

When it pays a distribution, the Fund provides holders of its Common Shares a notice of the estimated sources of the Fund’s distributions (i.e., what percentage of the distributions is estimated to constitute ordinary income, short-term capital gains, long-term capital gains, and/or a non-taxable return of capital) on a year-to-date basis. It does this by posting the notice on its website (www.nuveen.com/cef), and by sending it in written form.

You should not draw any conclusions about the Fund’s investment performance from the amount of this distribution or from the terms of the Fund’s Managed Distribution Policy. The Fund’s actual financial performance will likely vary from month-to-month and from year-to-year, and there may be extended periods when the distribution rate will exceed the Fund’s actual total returns. The Managed Distribution Policy provides that the Board may amend or terminate the Policy at any time without prior notice to Fund shareholders. There are presently no reasonably foreseeable circumstances that might cause the Fund to terminate its Managed Distribution Policy.

Chair’s Letter

to Shareholders

Dear Shareholders,

Markets have had a turbulent start to 2022. Global economic activity has been deteriorating from post-pandemic peaks, and crisis-era monetary and fiscal support programs are being phased out. Inflation has surged partially due to supply chain bottlenecks and exacerbated by Russia’s war in Ukraine and recent lockdowns across China to contain a large-scale COVID-19 outbreak.

We are now almost four months into the Eastern European conflict and are witnessing the scale of the humanitarian crisis and the economic impact caused by this event. Market uncertainty has remained elevated, as the situations in Russia/Ukraine and China have increased inflation and recession risks. The U.S. Federal Reserve (Fed) and other central banks now face an even more difficult task of slowing inflation without pulling the economy into recession. As anticipated, the Fed began the rate hiking cycle in March 2022, raising its short-term rate by 0.25% from near zero for the first time since the pandemic was declared two years ago, then made increasingly more aggressive moves of 0.50% in May and 0.75% in June 2022. Additional rate hikes of these larger magnitudes are expected this year, as inflation has lingered at a 40-year high and consumer sentiment indicators are slumping. Forecasting was made difficult given the wide range of potential outcomes with regard to the Russia-Ukraine war, the resilience of China’s economy, the reopening of supply chains, the impact of inflation on economic growth, and the Fed’s response to inflation. Accordingly, markets are struggling with pricing these risks.

In the meantime, while markets will likely continue fluctuating with the daily headlines, we encourage investors to keep a long-term perspective. To learn more about how well your portfolio is aligned to your time horizon, risk tolerance and investment goals, consider reviewing it with your financial professional.

On behalf of the other members of the Nuveen Fund Board, I look forward to continuing to earn your trust in the months and years ahead.

Terence J. Toth

Chair of the Board

Fund Leverage

IMPACT OF THE FUNDS’ LEVERAGE STRATEGIES ON PERFORMANCE

One important factor impacting the returns of the Funds’ common shares relative to their comparative benchmarks was the Funds’ use of leverage through their issuance of preferred shares, reverse repurchase agreements, borrowings and/or investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. The Funds use leverage because our research has shown that, over time, leveraging provides opportunities for additional income. The opportunity arises when short-term rates that a Fund pays on its leveraging instruments are lower than the interest a Fund earns on its portfolio of long-term bonds that it has bought with the proceeds of that leverage. This has been particularly true in the recent market environment where short-term rates have been low by historical standards.

However, use of leverage can expose Fund common shares to additional price volatility. When a Fund uses leverage, the Fund’s common shares will experience a greater increase in their net asset value if the municipal bonds acquired through the use of leverage increase in value, but will also experience a correspondingly larger decline in their net asset value if the bonds acquired through leverage decline in value. All this will make the shares’ total return performance more variable over time.

In addition, common share income in levered funds will typically decrease in comparison to unlevered funds when short-term interest rates increase and increase when short-term interest rates decrease. In recent quarters, fund leverage expenses have generally tracked the overall movement of short-term tax-exempt interest rates. While fund leverage expenses are somewhat higher than their recent lows, leverage nevertheless continues to provide the opportunity for incremental common share income, particularly over longer-term periods.

The use of leverage had a negative impact on the total return performance of the Funds over the reporting period.

As of April 30, 2022, the Funds’ percentages of leverage are as shown in the accompanying table.
