You will be charged a $2.50 service charge and pay brokerage charges if you direct Computershare Inc. and Computershare Trust Company, N.A., as agent for the common shareholders, to sell your Common Shares held in a dividend reinvestment account. Stated as percentages of average net assets attributable to Common Shares for the fiscal year ended October 31, 2023. Interest and Other Related Expenses reflect actual expenses and fees for leverage incurred by a Fund for the fiscal year ended October 31, 2023. The types of leverage used by each Fund during the fiscal year ended October 31, 2023 are described in the Fund Leverage and the Notes to Financial Statements (Note 4 – Portfolio Securities, Note 5 – Derivative Investments, Note 6 – Fund Shares, Note 10 – Borrowings Arrangements and Reverse Repurchase Agreements) sections of this annual report. Actual Interest and Other Related Expenses incurred in the future may be higher or lower. If short-term market interest rates rise in the future, and if a Fund continues to maintain leverage, the cost of which is tied to short-term interest rates, a Fund’s interest expenses on its short-term borrowings can be expected to rise in tandem. A Fund’s use of leverage will increase the amount of management fees paid to the Fund’s adviser and sub-advisor(s). Other Expenses are based on estimated amounts for the current fiscal year. Expenses attributable to the Fund’s investments, if any, in other investment companies are currently estimated not to exceed 0.01%. Not applicable – the Fund does not incur a sales charge for offerings pursuant to an underwritten transaction as noted in Shareholder Transaction Expenses table above. Aggregate Amount Outstanding: Aggregate amount outstanding represents the liquidation preference as of the end of the relevant fiscal year and does not include any preferred shares noticed for redemption as noted on the Statement of Assets and Liabilities, where applicable. Asset Coverage Per $100,000: Asset coverage per $100,000 is calculated by subtracting the Fund’s liabilities and indebtedness not represented by senior securities from the Fund’s total assets, dividing the result by the aggregate amount of the Fund’s senior securities representing indebtedness then outstanding (if applicable), plus the aggregate of the involuntary liquidation preference of the outstanding preferred shares, if applicable, and multiplying the result by 100,000. 0001090116 2022-11-01 2023-10-31 0001090116 2023-10-31 0001090116 2022-10-31 0001090116 2021-10-31 0001090116

Chair’s Letter
to Shareholders
 
LOGO   
Dear Shareholders,
 
Financial markets spent the past year focused on the direction of inflation and whether policy makers would be able to deliver a soft landing in their economies. After more than a year and a half of interest rate increases by the U.S. Federal Reserve (Fed) and other central banks, financial conditions have tightened and inflation rates have cooled considerably. The Fed increased the target fed funds rate from near zero in March 2022 to a range of 5.25% to 5.50% as of November 2023, with pauses in June 2023, September 2023 and November 2023. But current inflation rates remain above central banks’ targets, and the trajectory from here is difficult to predict given that monetary policy acts on the economy with long and variable lags.
 
Surprisingly, economies were relatively resilient for much of 2023. By
year-end,
the “most predicted recession” had yet to materialize in the U.S., while U.K. and European economic growth was just beginning to show signs of stagnation or decline. U.S. gross domestic product rose 5.2% in the third quarter of 2023, 2.1% in the second quarter of 2023 and 2.0% in the first quarter of 2023, after growing 2.1% in 2022 overall compared to 2021. Much of the growth was driven by a relatively strong jobs market, which kept consumer sentiment and spending elevated despite long-term interest rates nearing multi-year highs, a series of U.S. regional bank failures and shocks from flaring geopolitical tensions.
 
  
While central banks are likely nearing the end of this interest rate hiking cycle, there are still upside risks to inflation and downside risks to the economy. Some labor market and consumer indicators are softening. Government funding and deficits remain a concern, especially as the U.S. election year gets underway. The markets will continue to try to anticipate monetary policy shifts as the Fed evaluates incoming data and adjusts its rate setting activity on a
meeting-by-meeting
basis. Geopolitical risks – from relations with China, to wars in Europe and the Middle East – also expand the range of outcomes from economies and markets around the world. All these uncertainties, and others, will remain sources of short-term market volatility. In this environment, Nuveen remains committed to filtering the market noise for investable opportunities that ultimately serve long-term investment objectives. Maintaining a long-term perspective is also important for investors, and we encourage you to review your time horizon, risk tolerance and investment goals with your financial professional.
 
On behalf of the other members of the Nuveen Fund Board, we look forward to continuing to earn your trust in the months and years ahead.

Important Notices
Fund Mergers Update for Nuveen Municipal Credit Income Fund (NZF)
Effective prior to the opening of business on April 17, 2023, Nuveen Ohio Quality Municipal Income Fund (NUO) and Nuveen Georgia Quality Municipal Income Fund (NKG) were each merged into NZF (“each a Merger”). Refer to the Notes to Financial Statements within this report for further details on the Merger.
Portfolio Manager Updates
Effective April 10, 2023, Daniel Close, CFA, and Stephen Candido, CFA, were added as portfolio managers of NMZ, NMCO and NDMO. Effective May 31, 2023, John Miller no longer serves as a portfolio manager of NMZ, NMCO and NDMO. Effective October 13, 2023, Steven Hlavin was added as a portfolio manager of NVG. Effective October 13, 2023, Kristen DeJong, CFA, was added as a portfolio manager of NZF. There were no other changes to the portfolio management of the Funds during the reporting period.
Updated Distribution Policy for NDMO
On November 29, 2023, the Funds’ Board of Trustees (the “Board”) updated the Fund’s distribution policy. Effective for distributions payable on December 29, 2023, the Fund’s distribution policy, which may be changed by the Board, is to make regular monthly cash distributions to holders of its common shares (stated in terms of a fixed cents per common share dividend distribution rate which may be set from time to time). The Fund intends to distribute all or substantially all of its net investment income through its regular monthly distribution and to distribute realized capital gains at least annually. In addition, in any monthly period, to maintain its declared per common share distribution amount, the Fund may distribute more or less than its net investment income during the period. In the event the Fund distributes more than its net investment income during any yearly period, such distributions may also include realized gains and/or a return of capital. To the extent that a distribution includes a return of capital the NAV per share may erode. If the Fund’s distribution includes anything other than net investment income, the Fund will provide a notice to shareholders of its best estimate of the distribution sources at that the time of the distribution. These estimates may not match the final tax characterization (for the full year’s distributions) contained in shareholders’
1099-DIV
forms after the end of the year.

What factors affected the U.S. economy and market conditions during the twelve-month annual reporting period ended October 31, 2023?
The U.S. economy performed better than expected despite persistent inflationary pressure and rising interest rates during the twelve-month period ended October 31, 2023. Gross domestic product accelerated sharply in third quarter of 2023 to an annualized rate of 5.2%, according to the U.S. Bureau of Economic Analysis second estimate, up from 2.1% in the second quarter of 2023. By comparison, GDP grew 2.1% in 2022 overall. Early in the reporting period, inflation had risen sharply because of supply chain disruptions and high food and energy prices, the Russia-Ukraine war and China’s
zero-COVID
restrictions (lifted in December 2022). Since then, price pressures have eased given normalization in supply chains, falling energy prices and aggressive measures by the U.S. Federal Reserve (Fed) and other global central banks to tighten financial conditions and slow demand in their economies. Nevertheless, during the reporting period inflation levels remained much higher than central banks’ target levels.
The Fed raised its target fed funds rate six times during the reporting period, bringing it to a range of 5.25% to 5.50% as of July 2023 and voting to hold it at that level at its next two meetings held near the end of the reporting period. For much of the reporting period, the Fed’s activity led to significant volatility in bond and stock markets, given the uncertainty of how rising interest rates would affect the economy. One of the most highly visible impacts occurred in the U.S. regional banking sector in March 2023, when Silicon Valley Bank, Signature Bank, First Republic Bank and Silvergate Bank failed. In the same month, Swiss bank UBS agreed to buy Credit Suisse, which was considered vulnerable in the current environment. The Fed’s monetary tightening policy also contributed to an increase in the U.S. dollar’s value relative to major world currencies, which acts as a headwind to the profits of international companies and U.S. domestic companies with overseas earnings.
During the reporting period, elevated inflation and higher borrowing costs weighed on some segments of the economy, including the real estate market. Consumer spending, however, has remained more resilient than expected, in part because of a still-strong labor market, another key gauge of the economy’s health. As of October 2023, the unemployment rate was 3.9%, rising from its
pre-pandemic
low, with monthly job growth continuing to moderate. The strong labor market and wage gains helped the U.S. economy during the reporting period, even as the Fed sought to soften job growth to help curb inflation pressures.
During the reporting period, investors also continued to monitor government funding and deficits. The U.S. government avoided a default scenario after approving an increase to the debt ceiling limit in June 2023. At the same time, the potential for a government shutdown loomed but was ultimately avoided with funding resolutions passed in September 2023 and, subsequent to the close

of the reporting period, November 2023. Notably, in August 2023, ratings agency Fitch downgraded U.S. debt from AAA to AA+ based on concerns about the U.S.’s growing fiscal debt and reduced confidence in fiscal management.
The broad municipal bond market was impacted by interest rate volatility and economic uncertainty during the reporting period. Municipal yields rose across the maturity spectrum, but the move was uneven. The greatest increase in yields was at the shorter end of the curve as markets priced in a more aggressive pace of monetary tightening to combat persistently high inflation. Although municipal bonds continued to exhibit relatively strong credit fundamentals, there were periods of spread widening during the reporting period as the market
sell-off
continued.
Nuveen
AMT-Free
Municipal Credit Income Fund (NVG)
What key strategies were used to manage the Fund during the twelve-month reporting period ended October 31, 2023?
NVG’s investment objectives are to provide current income exempt from regular federal income tax and federal alternative minimum tax applicable to individuals, and to enhance portfolio value relative to the municipal bond market. The Fund invests in
tax-exempt
municipal bonds that the portfolio management teams believe are underrated or undervalued or that represent municipal market sectors that are undervalued and uses leverage. Leverage is discussed in more detail in the Fund Leverage section of this report.
During the reporting period, the Fund’s trading activity remained focused on pursuing its investment objectives. The rising yield environment during this reporting period was favorable for the Fund to reset embedded yields higher in its portfolio, primarily by executing on
tax-loss
swap opportunities. This strategy involves selling depreciated bonds with lower embedded yields to reinvest in similarly structured, higher income-producing bonds to support the Fund’s income earnings and capture tax efficiencies.
As of October 31, 2023, the Fund continued to use inverse floating rate securities. The Fund employs inverse floating rate securities, which are the residual interest in a tender option bond (TOB) trust, and are sometimes referred to as “inverse floaters,” for a variety of reasons, including duration management and income and total return enhancement.
How did the Fund perform during the twelve-month reporting period ended October 31, 2023?
For the twelve-month reporting period ended October 31, 2023, NVG underperformed the NVG Blended Benchmark. For purposes of this Performance Commentary, references to relative performance are in comparison to the NVG Blended Benchmark, which consists of 1) 60% S&P Municipal Bond Investment Grade Index and 2) 40% S&P Municipal Bond High Yield Index.
The primary detractor from NVG’s relative performance was the Fund’s use of leverage through its issuance of preferred shares and investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. Leverage is discussed in more detail in the Fund Leverage section of this report.
Partially offsetting NVG’s underperformance were its underweight to shorter maturity bonds and corresponding overweight to longer maturity bonds. Additionally, the Fund’s credit quality positioning was also advantageous, as credit spreads narrowed occasionally throughout the period. The Fund continued to emphasize bonds rated
mid-investment
grade and lower, which contributed positively to relative performance.
Nuveen Municipal Credit Income Fund (NZF)
What key strategies were used to manage the Fund during the twelve-month reporting period ended October 31, 2023?
NZF’s investment objectives are to provide current income exempt from regular federal income tax and to enhance portfolio value relative to the municipal bond market. The Fund invests in
tax-exempt
municipal bonds that the portfolio management teams believe are underrated or undervalued or that represent municipal market sectors that are undervalued and uses leverage. Leverage is discussed in more detail in the Fund Leverage section of this report.
During the reporting period, the Fund’s trading activity remained focused on pursuing its investment objectives. The rising yield environment during this reporting period was favorable for the Fund to reset embedded yields higher in its portfolio, primarily by executing on
tax-loss
swap opportunities. This strategy involves selling depreciated bonds with lower embedded yields to reinvest in similarly structured, higher income-producing bonds to support the Fund’s income earnings and capture tax efficiencies.

Additionally, NZF continued its rotation into lower rated credit by selling AAA and AA rated bonds, which were purchased when rates were lower as temporary placeholders because of their liquidity profiles. The portfolio management team reinvested the proceeds in A, BBB and below investment grade rated bonds. As a result of this rotation strategy, the Fund’s exposures to the health care and transportation sectors increased while exposures to dedicated tax,
pre-refunded,
and water and sewer bonds decreased.
As of October 31, 2023, the Fund continued to use inverse floating rate securities. The Fund employs inverse floating rate securities, which are the residual interest in a tender option bond (TOB) trust, and are sometimes referred to as “inverse floaters,” for a variety of reasons, including duration management and income and total return enhancement.
How did the Fund perform during the twelve-month reporting period ended October 31, 2023?
For the twelve-month reporting period ended October 31, 2023, NZF underperformed the NZF Blended Benchmark. For purposes of this Performance Commentary, references to relative performance are in comparison to the NZF Blended Benchmark, which consists of 1) 60% S&P Municipal Bond Investment Grade Index and 2) 40% S&P Municipal Bond High Yield Index.
The primary detractor from NZF’s relative performance was the Fund’s use of leverage through its issuance of preferred shares and investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. Leverage is discussed in more detail in the Fund Leverage section of this report.
Partially offsetting NZF’s underperformance were its underweight to shorter-maturity bonds and corresponding overweight to longer maturity bonds. NZF also benefited from its overweight to the transportation sector, particularly “other transportation” bonds, which was one of the better-performing sectors during the period. The Fund’s credit quality positioning was also advantageous, as credit spreads narrowed occasionally throughout the period. Overweight allocations to mid investment grade and lower added to relative performance as these categories outperformed the highest investment grade categories.
Nuveen Municipal High Income Opportunity Fund (NMZ)
What key strategies were used to manage the Fund during the twelve-month reporting period ended October 31, 2023?
NMZ’s primary investment objective is to provide high current income exempt from regular federal income tax. Its secondary investment objective is to seek attractive total return consistent with its primary objective. NMZ invests in an actively managed portfolio of
tax-exempt
municipal securities and uses leverage. Leverage is discussed in more detail in the Fund Leverage section of this report.
During the reporting period, the Fund’s trading activity remained focused on pursuing its investment objectives. The rising yield environment during this reporting period was favorable for the Fund to reset embedded yields higher in its portfolio, primarily by executing on
tax-loss
swap opportunities. This strategy involves selling depreciated bonds with lower embedded yields to reinvest in similarly structured, higher income-producing bonds to support the Fund’s income earnings and capture tax efficiencies. The portfolio management team also reduced the Fund’s equity positions in American Airlines and Talen Energy (both of which were acquired in restructurings) when it was favorable to do so during the reporting period.
As of October 31, 2023, the Fund continued to use inverse floating rate securities. The Fund employs inverse floating rate securities, which are the residual interest in a tender option bond (TOB) trust, and are sometimes referred to as “inverse floaters,” for a variety of reasons, including duration management and income and total return enhancement.
How did the Fund perform during the twelve-month reporting period ended October 31, 2023?
For the twelve-month reporting period ended October 31, 2023, NMZ underperformed the S&P Municipal Yield Index. For purposes of this Performance Commentary, references to relative performance are in comparison to the S&P Municipal Yield Index.
The primary detractor from NMZ’s relative performance was the Fund’s use of leverage through its issuance of preferred shares and investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. However, the Fund’s use of leverage was accretive to overall common share income. Leverage is discussed in more detail in the Fund Leverage section of this report.

Portfolio Managers’ Comments
(continued)
 
Leading individual detractors included the Fund’s exposures to Puerto Rico Electric Power Authority (PREPA) bonds and certain project finance bonds, which faced a variety of project-specific challenges during the period. PREPA underperformed given the issuer’s ongoing restructuring. The Fund continued to hold PREPA based on the portfolio management team’s outlook.
Partial offsets to NMZ’s relative underperformance included its, credit quality positioning. Credit spreads narrowed occasionally throughout the period and the Fund benefited from an overweight to
non-rated
bonds and a corresponding underweight to the highest grade (AAA and AA rated) bonds.
Nuveen Municipal Credit Opportunities Fund (NMCO)
What key strategies were used to manage the Fund during the twelve-month reporting period ended October 31, 2023?
NMCO’s primary investment objective is to provide a high level of current income exempt from regular U.S. federal income tax and secondarily, total return. NMCO invests primarily in high yielding, low to medium-quality municipal securities, and uses leverage. Leverage is discussed in more detail in the Fund Leverage section of this report.
During the reporting period, the Fund’s trading activity remained focused on pursuing its investment objectives. The rising yield environment during this reporting period was favorable for the Fund to reset embedded yields higher in its portfolio, primarily by executing on
tax-loss
swap opportunities. This strategy involves selling depreciated bonds with lower embedded yields to reinvest in similarly structured, higher income-producing bonds to support the Fund’s income earnings and capture tax efficiencies. Additionally, NMCO was active in reducing leverage levels during the reporting period. Please see the Notes to Financial Statements for additional details.
As of October 31, 2023, the Fund continued to use inverse floating rate securities. The Fund employs inverse floating rate securities, which are the residual interest in a tender option bond (TOB) trust, and are sometimes referred to as “inverse floaters,” for a variety of reasons, including duration management and income and total return enhancement.
How did the Fund perform during the twelve-month reporting period ended October 31, 2023?
For the twelve-month reporting period ended October 31, 2023, NMCO significantly underperformed the S&P Municipal Yield Index. For purposes of this Performance Commentary, references to relative performance are in comparison to the S&P Municipal Yield Index.
The primary driver of NMCO’s underperformance was the Fund’s use of leverage, which detracted significantly. The Fund uses leverage through its issuance of preferred shares and investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. Leverage is discussed in more detail in the Fund Leverage section of this report.
Further, the Fund’s exposure to Puerto Rico Electric Power Authority (PREPA) bonds detracted. PREPA underperformed given the ongoing restructuring, along with certain underperforming project finance bonds that faced project-specific challenges during the period. The Fund continued to hold PREPA based on the portfolio management team’s outlook.
Partially offsetting the Fund’s underperformance was its credit quality positioning, as credit spreads narrowed occasionally throughout the period. The Fund benefited from its overweights to below investment grade and
non-rated
bonds. Additional contributors included overweights to sectors such as transportation and dedicated tax, which were some of the
top-performing
sectors.
Nuveen Dynamic Municipal Opportunities Fund (NDMO)
What key strategies were used to manage the Fund during the twelve-month reporting period ended October 31, 2023?
NDMO’s investment objective is to provide total return through income exempt from regular federal income taxes and capital appreciation. NDMO invests primarily in municipal securities, the income on which is exempt from regular U.S. federal income tax and uses leverage. Leverage is discussed in more detail in the Fund Leverage section of this report.
During the reporting period, the Fund’s trading activity remained focused on pursuing its investment objectives. The rising yield environment during this reporting period was favorable for the Fund to reset embedded yields higher in its portfolio, primarily by

executing on
tax-loss
swap opportunities. This strategy involves selling depreciated bonds with lower embedded yields to reinvest in similarly structured, higher income-producing bonds to support the Fund’s income earnings and capture tax efficiencies.
Additionally, during the reporting period NDMO was active in reducing leverage levels. Please see the Notes to Financial Statements for additional details. NDMO also actively sought to reduce its overall duration profile by selling positions in longer-duration bonds and by collapsing certain tender option bond (TOB) structures that were no longer cost-efficient because of rising borrowing costs.
As of October 31, 2023, the Fund continued to use inverse floating rate securities. The Fund employs inverse floating rate securities, which are the residual interest in a tender option bond (TOB) trust, and are sometimes referred to as “inverse floaters,” for a variety of reasons, including duration management and income and total return enhancement.
How did the Fund perform during the twelve-month reporting period ended October 31, 2023?
For the twelve-month reporting period ended October 31, 2023, NDMO underperformed the S&P Municipal Bond Index. For purposes of this Performance Commentary, references to relative performance are in comparison to the S&P Municipal Bond Index.
The primary detractor from NDMO’s relative performance was the Fund’s use of leverage through its issuance of preferred shares and investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. Leverage is discussed in more detail in the Fund Leverage section of this report.
Further, the Fund’s exposure to Puerto Rico Electric Power Authority (PREPA) bonds detracted. PREPA underperformed given the ongoing restructuring, along with certain underperforming project finance bonds that faced project-specific challenges during the period. The Fund continued to hold PREPA based on the portfolio management team’s outlook.
Partially offsetting the Fund’s underperformance were its overweights to the tobacco, transportation and dedicated tax sectors, which performed well, and an underweight to housing, which underperformed. In addition, NDMO was aided by strong performance from positions in Brightline, Puerto Rico sales tax revenue bonds known as COFINAs, Big River Steel and American Dream, and an opportunistic investment in short-term Treasury bills. The Fund continued to maintain exposures to the credits listed above but closed out its position in Treasury bills prior to the end of the reporting period.
The Fund managed the duration of its portfolio by shorting interest rate futures contracts. The interest rate futures contracts had a negligible impact on relative performance during the reporting period.

Fund Leverage
IMPACT OF THE FUNDS’ LEVERAGE STRATEGY 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 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 the Fund earns on its portfolio of long-term bonds that it has bought with the proceeds of that leverage.
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 securities acquired through the use of leverage increase in value, but will also experience a correspondingly larger decline in their net asset value if the securities 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 interest rates. While fund leverage expenses are higher than their prior year lows, leverage nevertheless continues to provide the opportunity for incremental common share income, particularly over longer-term periods.
NVG, NZF, NMZ and NDMO’s use of leverage detracted from relative performance over this reporting period while NMCO’s use of leverage significantly detracted. However, NMZ’s use of leverage was accretive to overall common share income.
As of October 31, 2023, the Funds’ percentages of leverage are as shown in the accompanying table.

Effective Leverage is a Fund’s effective economic leverage, and includes both regulatory leverage and the leverage effects of certain derivative and other investments in a Fund’s portfolio that increase the Fund’s investment exposure. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any regulatory leverage. Regulatory leverage consists of preferred shares issued or borrowings of a Fund. Both of these are part of a Fund’s capital structure. A Fund, however, may from time to time borrow on a typically transient basis in connection with its
day-to-day
operations, primarily in connection with the need to settle portfolio trades. Such incidental borrowings are excluded from the calculation of a Fund’s effective leverage ratio. Regulatory leverage is subject to asset coverage limits set forth in the Investment Company Act of 1940.

Market Yield is based on the Fund’s current annualized monthly dividend divided by the Fund’s current market price as of the end of the reporting period. Taxable-Equivalent Yield represents the yield that must be earned on a fully taxable investment in order to equal the yield of the Fund on an
after-tax
basis. It is based on a federal income tax rate of 40.8%. Your actual federal income tax rate may differ from the assumed rate. The Taxable-Equivalent Yield also takes into account the percentage of the Fund’s income generated and paid by the Fund (based on payments made during the previous calendar year) that was not exempt from federal income tax. Separately, if the comparison were instead to investments that generate qualified dividend income, which is taxable at a rate lower than an individual’s ordinary graduated tax rate, the fund’s Taxable-Equivalent Yield would be lower.
NVG, NZF, NMZ and NMCO seek to pay regular monthly dividends out of their net investment income at a rate that reflects their past and projected net income performance. To permit each Fund to maintain a more stable monthly dividend, the Fund may pay dividends at a rate that may be more or less than the amount of net income actually earned by the Fund during the period. Distributions to common shareholders are determined on a tax basis, which may differ from amounts recorded in the accounting records. In instances where the monthly dividend exceeds the earned net investment income, the Fund would report a negative undistributed net ordinary income. Refer to Notes to Financial Statements for additional information regarding the amounts of undistributed net ordinary income and undistributed net long-term capital gains and the character of the actual distributions paid by the Fund during the period.
All monthly dividends paid by NVG and NZF during the current reporting period were paid from net investment income. If a portion of the Fund’s monthly distributions is sourced or comprised of elements other than net investment income, including capital gains and/or a return of capital, shareholders will be notified of those sources. During the current fiscal period, NMZ’s and NMCO’s distributions were slightly greater than each Fund’s interest income, net of Fund expenses. As a result a portion of NMZ’s and NMCO’s distributions were deemed to be a return of capital. For financial reporting purposes, the per share amounts of each Fund’s distributions for the reporting period are presented in this report’s Financial Highlights. For income tax purposes, distribution information for each Fund as of its most recent tax year end is presented within the Notes to Financial Statements of this report.
Updated Distribution Policy for NVG, NZF, NMZ and NMCO
On October 23, 2023, the Funds’ Board of Trustees (the “Board”) updated each Fund’s distribution policy. Effective for distributions payable on December 1, 2023, each Fund’s distribution policy, which may be changed by the Board, is to make regular monthly cash distributions to holders of its common shares (stated in terms of a fixed cents per common share dividend distribution rate which may be set from time to time). The Fund intends to distribute all or substantially all of its net investment income through its regular monthly distribution and to distribute realized capital gains at least annually. In addition, in any monthly period, to maintain its declared per common share distribution amount, the Fund may distribute more or less than its net investment income during the period. In the event the Fund distributes more than its net investment income during any yearly period, such distributions may also include realized gains and/or a return of capital. To the extent that a distribution includes a return of capital the NAV per share may erode. If the Fund’s distribution includes anything other than net investment income, the Fund will provide a notice to shareholders of its best estimate of the distribution sources at that the time of the distribution. These estimates may not match the final tax characterization (for the full year’s distributions) contained in shareholders’
1099-DIV
forms after the end of the year.

Common Share Information  
(continued)
 
COMMON SHARE DISTRIBUTION INFORMATION FOR NDMO
NDMO makes regular cash distributions to shareholders of a stated dollar amount per share. Subject to approval and oversight by the Board of Trustees, the Fund seeks to maintain a stable distribution level designed to deliver the long-term return potential of the Fund’s investment strategy through regular distributions (a “Managed Distribution Program”). The practice of maintaining a stable distribution level had no material effect on the Fund’s investment strategy during the most recent fiscal period and is not expected to have such an effect in future periods, however, distributions in excess of Fund returns will cause its NAV per share to erode. For additional information, refer to the distribution information section below and in the Notes to Financial Statements herein.
This notice provides shareholders with information regarding fund distributions, as required by current securities laws. 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 following table provides estimates of the Fund’s distribution sources, reflecting
year-to-date
cumulative experience through the
month-end
prior to the latest distribution. The Fund attributes these estimates equally to each regular distribution throughout the year. Consequently, the estimated information as of the specified
month-end
shown below is for the current distribution, and also represents an updated estimate for all prior months in the year. It is estimated that the Fund has distributed more than its income and net realized capital gains; therefore, a portion of the distributions may be (and is shown below as being estimated to be) a return of capital. A return of capital may occur, for example, when some or all of the money that you invested in the Fund is paid back to you. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.”
The amounts and sources of distributions reported in this notice are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon the Fund’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Fund will send a Form
1099-DIV
for the calendar year that will tell you how to report these distributions for federal income tax purposes. More details about the Fund’s distributions and the basis for these estimates are available on www.nuveen.com/cef.

Report of Independent Registered
Public Accounting Firm
To the Board of Trustees and Shareholders of Nuveen
AMT-Free
Municipal Credit Income Fund, Nuveen Municipal Credit Income Fund, Nuveen Municipal High Income Opportunity Fund, Nuveen Municipal Credit Opportunities Fund, and Nuveen Dynamic Municipal Opportunities Fund
Opinion on the Financial Statements
We have audited the accompanying statements of assets and liabilities of the Funds Listed in Appendix A (the Funds), including the portfolios of investments, as of October 31, 2023, the related statements of operations, cash flows and changes in net assets for the Funds and periods listed in Appendix A, and the related notes (collectively, the financial statements) and the financial highlights for the Funds and periods listed in Appendix A. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Funds as of October 31, 2023, the results of their operations, cash flows and the changes in their net assets for the periods listed in Appendix A, and the financial highlights for the Funds and periods listed in Appendix A, in conformity with U.S. generally accepted accounting principles.
Basis for Opinion
These financial statements and financial highlights are the responsibility of the Funds’ 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 Funds 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 October 31, 2023, by correspondence with custodians and brokers; when replies were not received from brokers, we performed other auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

Various funds and accounts managed by Nuveen, including the Fund, collectively are a substantial minority holder of ENGH’s outstanding shares of common stock, and possess certain other rights with respect to the corporate governance of ENGH. Due to these facts, under the federal securities laws, the securities of ENGH held by Nuveen funds and accounts, including the Fund, cannot be sold except under limited conditions (which are not currently satisfied). The Fund is therefore unable to sell such shares in ordinary secondary market transactions at this time. On March 6, 2023 Vistra Corp. (“Vistra”) announced that it has executed a definitive agreement with Energy Harbor Corp., pursuant to which Energy Harbor will merge with and into a newly-formed subsidiary of Vistra. In connection with the transaction, Nuveen funds and accounts expect to receive a combination of cash and shares in a newly formed entity. Nuveen expects these shares to be issued in a private transaction and may have reduced secondary market liquidity. The transaction is subject to certain regulatory approvals and there can be no assurance that the transaction will close.

Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.
(c)
Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities, which ensure the timely payment of principal and interest.
(d)
Investment, or portion of investment, has been pledged to collateralize the net payment obligations for investments in inverse floating rate transactions.
(e)
Defaulted security. A security whose issuer has failed to fully pay principal and/or interest when due, or is under the protection of bankruptcy.
(f)
For fair value measurement disclosure purposes, investment classified as Level 3.
(g)
Step-up
coupon bond, a bond with a coupon that increases (“steps up”), usually at regular intervals, while the bond is outstanding. The rate shown is the coupon as of the end of the reporting period.
(h)

(i)
Energy Harbor Corp (ENGH) common stock received as part of the bankruptcy settlements during February 2020 for Beaver County Industrial Development Authority, Pennsylvania, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generation Project, Series 2006B, 3.500%, 12/01/35, Ohio Air Quality Development Authority, Ohio, Pollution Control Revenue Bonds, FirstEnergy Nuclear Generation Project, Refunding Series 2008C, 3.950%, 11/01/32, Ohio Water Development Authority, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generating Corporation Project, Series 2008C, 3.950%, 11/01/32. Various funds and accounts managed by Nuveen, including the Fund, collectively are a substantial minority holder of ENGH’s outstanding shares of common stock, and possess certain other rights with respect to the corporate governance of ENGH. Due to these facts, under the federal securities laws, the securities of ENGH held by Nuveen funds and accounts, including the Fund, cannot be sold except under limited conditions (which are not currently satisfied). The Fund is therefore unable to sell such shares in ordinary secondary market transactions at this time. On March 6, 2023 Vistra Corp. (“Vistra”) announced that it has executed a definitive agreement with Energy Harbor Corp., pursuant to which Energy Harbor will merge with and into a newly-formed subsidiary of Vistra. In connection with the transaction, Nuveen funds and accounts expect to receive a combination of cash and shares in a newly formed entity. Nuveen expects these shares to be issued in a private transaction and may have reduced secondary market liquidity. The transaction is subject to certain regulatory approvals and there can be no assurance that the transaction will close.

Various funds and accounts managed by Nuveen, including the Fund, collectively are a substantial minority holder of ENGH’s outstanding shares of common stock, and possess certain other rights with respect to the corporate governance of ENGH. Due to these facts, under the federal securities laws, the securities of ENGH held by Nuveen funds and accounts, including the Fund, cannot be sold except under limited conditions (which are not currently satisfied). The Fund is therefore unable to sell such shares in ordinary secondary market transactions at this time. On March 6, 2023 Vistra Corp. (“Vistra”) announced that it has executed a definitive agreement with Energy Harbor Corp., pursuant to which Energy Harbor will merge with and into a newly-formed subsidiary of Vistra. In connection with the transaction, Nuveen funds and accounts expect to receive a combination of cash and shares in a newly formed entity. Nuveen expects these shares to be issued in a private transaction and may have reduced secondary market liquidity. The transaction is subject to certain regulatory approvals and there can be no assurance that the transaction will close.
(j)
Non-income
producing; issuer has not declared an
ex-dividend
date within the past twelve months.
(k)
Senior loans generally pay interest at rates which are periodically adjusted by reference to a base short-term, floating lending rate (Reference Rate) plus an assigned fixed rate (Spread). These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate (“LIBOR”), or (ii) the prime rate offered by one or more major United States banks. Senior loans may be considered restricted in that the Fund ordinarily is contractually obligated to receive approval from the agent bank and/or borrower prior to the disposition of a senior loan. The rate shown is the coupon as of the end of the reporting period.
(l)
Senior loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for a borrower to prepay, prepayments of senior loans may occur. As a result, the actual remaining maturity of senior loans held may be substantially less than the stated maturities shown.
