1The contingent deferred sales charge on Class C shares applies only to redemptions within 12 months of purchase.

2Management Fees have been restated to reflect current contractual fees.

3The Fund's investment adviser has agreed to waive fees and/or reimburse expenses through July 31, 2026 so that the total annual operating expenses of the Fund (excluding 12b-1 distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities and extraordinary expenses) do not exceed 1.00% of the average daily net assets of any class of Fund shares. However, because Class R6 shares are not subject to sub-transfer agent and similar fees, the total annual operating expenses for the Class R6 shares will be less than the expense limitation. This expense limitation may be terminated or modified prior to July 31, 2026 only with the approval of the Board of Directors of the Fund.

Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year, that the Fund's operating expenses remain the same and that the fee waivers currently in place are not renewed beyond July 31, 2026. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

			Class A		Class C		Class R6		Class I
1 Year				$	692		$	200		$	92		$	99
3 Years				$	947		$	625		$	294		$	316
5 Years				$	1,231		$	1,087		$	524		$	562
10 Years				$	2,038		$	2,365		$	1,185		$	1,266

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 90% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in equity securities issued by U.S. and non-U.S. infrastructure-related companies. Infrastructure-related companies include companies involved in the ownership, development, construction, renovation, financing or operation of infrastructure assets, or that provide the services and raw materials necessary for the construction and maintenance of infrastructure assets. Infrastructure assets are the physical structures and networks upon which the operation, growth and development of a community depends, which include water, sewer, and energy utilities; transportation and communication networks; health care facilities, government accommodations, and other public service facilities; and shipping, timber, steel, alternative energy, and other resources and services necessary for the construction and maintenance of these physical structures and networks.

Equity securities in which the Fund invests include common and preferred securities, publicly-traded units of master limited partnerships ("MLPs"), and real estate investment trusts ("REITs"). The Fund may also invest in exchange-traded funds ("ETFs") and other investment companies ("investment companies"). The Fund may invest in companies of any size, including small- and mid-capitalization companies.

In selecting securities, the Fund's sub-adviser invests in companies that it believes meet one or more of the following criteria:

·Attractively valued relative to other companies in the same industry or market.

2

·Strong fundamentals, including consistent cash flows or growth and a sound balance sheet.

·Strong management teams.

·Long-term contracts to provide infrastructure-based services.

·An identifiable catalyst that could increase the value of the company's securities over the next one or two years.

The Fund's sub-adviser generally will sell a security if any of the following has occurred:

·The security has hit its price target and the company is no longer attractively valued relative to other companies.

·The company's fundamentals have significantly deteriorated.

·There has been a significant change in the company's management team.

·A catalyst that could decrease the value of the security has been identified, or a previously existing positive catalyst has disappeared.

·A better alternative exists in the marketplace.

The Fund's investments include infrastructure-related securities of non-U.S. issuers. Under normal market conditions, the Fund will invest at least 40% of its net assets in securities of non-U.S. issuers and, in any case, will invest at least 30% of its net assets in such issuers.

The Fund diversifies its investments among a number of different countries throughout the world. Up to 25% of the Fund's total assets may be invested in equity securities of emerging market issuers.

The Fund may utilize derivatives, including options, futures contracts, options on futures contracts, and forward foreign currency exchange contracts. The Fund may use these derivatives to manage market or business risk, enhance the Fund's return, or hedge against adverse movements in currency exchange rates.

Principal Risks

The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund listed below are presented alphabetically to facilitate your ability to find particular risks and compare them with the risks of other funds. The significance of any specific risk to an investment in the Fund will vary over time depending on the composition of the Fund's portfolio, market conditions and other factors. Each risk summarized below is considered a "principal risk" of investing in the Fund, regardless of the order in which it appears.

Active Management Risk-The Fund's sub-adviser actively manages the Fund's investments. Consequently, the Fund is subject to the risk that the investment techniques and risk analyses employed by the Fund's sub-adviser may not produce the desired results. This could cause the Fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Currency Risk-Changes in currency exchange rates will affect the value of non-U.S. securities, the value of dividends and interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund's portfolio.

Cybersecurity Risk-Cybersecurity risk is the risk of an unauthorized breach and access to Fund assets, customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, its investment adviser or sub-adviser, custodian, transfer agent, distributor or other service provider, a financial intermediary or the issuers of securities held by the Fund to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund, its service providers or the issuers of securities held by the Fund may adversely impact the Fund or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund's investments to lose value.

Derivatives Risk-The use of derivatives involves additional risks and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivative instruments can be used to acquire or to transfer the risk and returns of a security or other asset without buying or selling the security or asset, and the risks associated with investing in such derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments, including leverage risk, market risk, counterparty risk, liquidity risk, operational risk and legal risk. These instruments may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives can result in losses that greatly exceed the original investment. Derivatives can be highly volatile, illiquid and difficult to value. An over-the-counter derivative transaction between the Fund and a counterparty that is not cleared through a central counterparty also involves the risk that a loss may be sustained as a result of the failure of

3

the counterparty to the contract to make required payments. The payment obligation for a cleared derivative transaction is guaranteed by a central counterparty, which exposes the Fund to the creditworthiness of the central counterparty.

Emerging Markets Risk-The risk of foreign investment often increases in countries with emerging markets or that are otherwise economically tied to emerging market countries. For example, these countries may have more unstable governments than developed countries and their economies may be based on only a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, which would affect the Fund's ability to evaluate potential portfolio companies. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund's sub-adviser to evaluate local companies or their potential impact on the Fund's performance. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries.

Equity Security Risk-Equity securities in the Fund's portfolio may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular country, company, industry, or sector of the market.

ETF Risk-An ETF is subject to the risks of the underlying securities that it holds. In addition, for index-based ETFs, the performance of an ETF may diverge from the performance of such index (commonly known as tracking error). ETFs are subject to fees and expenses (like management fees and operating expenses) that do not apply to an index, and the Fund will indirectly bear its proportionate share of any such fees and expenses paid by the ETFs in which it invests. Moreover, ETF shares may trade at a premium or discount to their net asset value. As ETFs trade on an exchange, they are subject to the risks of any exchange-traded instrument, including: (i) an active trading market for its shares may not develop or be maintained, (ii) market makers or authorized participants may decide to reduce their role or step away from these activities in times of market stress, (iii) trading of its shares may be halted by the exchange, and (iv) its shares may be delisted from the exchange.

Foreign Investment Risk-Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad, as well as armed conflicts and different legal, regulatory and tax environments. Foreign investments may also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent the Fund invests a significant portion of its assets in the securities of companies in a single country or region, it may be more susceptible to adverse economic, market, political or regulatory events or conditions affecting that country or region. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information, less stringent investor protections and less stringent accounting, corporate governance, financial reporting and disclosure standards.

Frequent Trading Risk-The Fund's portfolio turnover rate may exceed 100%. Frequent trading of portfolio securities may produce capital gains, which are taxable to shareholders when distributed. Frequent trading may also increase the amount of commissions or mark-ups to broker-dealers that the Fund pays when it buys and sells securities, which may detract from the Fund's performance.

Infrastructure Sector Risk-Because the Fund invests significantly in infrastructure-related securities, the Fund has greater exposure to adverse economic, regulatory, political, legal and other changes affecting the issuers of such securities. Additionally, infrastructure-related entities may be subject to regulation by various governmental authorities and affected by government regulation of rates charged to consumers, service interruptions, environmental matters or the imposition of special tariffs and changes in tax law. Infrastructure companies may be focused in the energy, industrials and utilities sectors. At times, the performance of securities in these infrastructure sectors may lag the performance of other sectors or the broader market as a whole. A downturn in these sectors could have an adverse impact on the Fund.

Market Risk-The market value of the Fund's investments may go up or down, sometimes rapidly or unpredictably and for short or extended periods of time, due to the particular circumstances of individual issuers or due to general conditions impacting issuers more broadly. Global economies and financial markets have become highly interconnected, and thus economic, market or political conditions or events in one country or region might adversely impact the value of the Fund's investments whether or not the Fund invests in such country or region. Events such as war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may have a severe

4

negative impact on the global economy, could cause financial markets to experience extreme volatility and losses, and could result in the disruption of trading and the reduction of liquidity in many instruments. Additionally, as inflation increases, the value of the Fund's assets can decline.

Master Limited Partnership Risk-An investment in an MLP exposes the Fund to the legal and tax risks associated with investing in partnerships. MLPs may have limited financial resources, their securities may be relatively illiquid, and they may be subject to more erratic price movements because of the underlying assets they hold.

Other Investment Companies Risk-When the Fund invests in other investment companies, including ETFs, you bear both your proportionate share of Fund expenses and, indirectly, the expenses of the other investment companies. Furthermore, the Fund is exposed to the risks to which the other investment companies may be subject.

Preferred Security Risk-Preferred securities generally are subordinated to bonds and other debt instruments in a company's capital structure and therefore will be subject to greater credit risk than those debt instruments. In addition, preferred securities are subject to other risks, such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having floating interest rates or dividends, which may result in a decline in value in a falling interest rate environment, having fixed interest rates or dividends, which may result in a decline in value in a rising interest rate environment, having limited liquidity, changing or unfavorable tax treatments and possibly being issued by companies in heavily regulated industries.

Real Estate Investment Risk-The Fund's investments in the real estate market have many of the same risks as direct ownership of real estate. These risks include, among others: declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds or other limits to accessing the credit or capital markets; defaults by borrowers or tenants, particularly during an economic downturn; and changes in interest rates. The real estate sector is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Real estate values have been subject to substantial fluctuations and declines on a local, regional and national basis in the past and may continue to be in the future.

REITs Risk- In addition to the risks associated with investing in securities of real estate companies and real estate related companies, REITs are subject to certain additional risks. REITs may be affected by changes in real estate values, rents, property taxes and interest rates. Further, REITs are dependent upon specialized management skills and cash flows, and may have their investments in relatively few properties, or in a small geographic area or a single property type. Failure of a company to qualify as a REIT under federal tax law, or changes to federal tax law or regulations governing REITs, may have adverse consequences to the Fund. In addition, REITs have their own expenses, and the Fund will bear a proportionate share of those expenses. Many REITs utilize leverage (and some may be highly leveraged), which increases investment risk and could potentially magnify the Fund's losses.

Small- and Mid-Cap Company Risk-Even larger REITs may be small- to medium-sized companies in relation to the equity markets as a whole. Securities of small-cap companies involve substantial risk. Prices of small-cap securities may be subject to more abrupt or erratic movements, and to wider fluctuations and lower liquidity, than security prices of larger, more established companies or broader market averages in general. It may be difficult to sell small-cap securities at the desired time and price. While mid-cap securities may be slightly less volatile than small-cap securities, they still involve similar risks.

Fund Performance

The following bar chart and table provide some indication of the potential risks of investing in the Fund. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/performance or by calling (800) 257-8787.

The bar chart below shows the variability of the Fund's performance from year to year for Class A shares. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.

Class A Annual Total Return*

*Class A year-to-date total return as of March 31, 2024 was 0.82%. The performance of the other share classes will differ due to their different expense structures.

During the ten-year period ended December 31, 2023, the Fund's highest and lowest quarterly returns were 14.66%
and -22.81%, respectively, for the quarters ended March 31, 2019 and March 31, 2020.

The table below shows the variability of the Fund's average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.

Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers had not been in place, returns would have been reduced.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank or financial advisor), the Fund, its distributor or its investment adviser may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary and your salesperson to recommend the Fund over another investment. Ask your financial advisor or visit your financial intermediary's website for more information.
