Nuveen Small Cap Select Fund

Investment Objective

The investment objective of the Fund is capital appreciation.

Fees and Expenses of the Fund

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Nuveen Mutual Funds. More information about these and other discounts, as well as eligibility requirements for each share class, is available from your financial advisor and in “How You Can Buy and Sell Shares” on page 56 of the Fund’s prospectus and “Purchase and Redemption of Fund Shares” on page S-69 of the Fund’s statement of additional information. In addition, more information about sales charge discounts and waivers for purchases of shares through specific financial intermediaries is set forth in the appendix to the Fund’s prospectus entitled “Variations in Sales Charge Reductions and Waivers Available Through Certain Intermediaries.”

The tables and examples below do not reflect any commissions that shareholders may be required to pay directly to their financial intermediaries when buying or selling Class I shares.

	Class A			Class C			Class R6			Class I
Management Fees		0.85	%		0.85	%		0.85	%		0.85	%

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

2Fee applies to the following types of accounts under $1,000 held directly with the Fund: individual retirement accounts (IRAs), Coverdell Education Savings Accounts and accounts established pursuant to the Uniform Transfers to Minors Act (UTMA) or Uniform Gifts to Minors Act (UGMA).

3The Fund’s investment adviser has agreed to waive fees and/or reimburse expenses through July 31, 2022 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 0.99% 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 that date 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, 2022. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

2

	Class A		Class C		Class R6		Class I
1 Year	$	694	$	202	$	88	$	101
3 Years	$	984	$	664	$	314	$	356
5 Years	$	1,306	$	1,164	$	569	$	643
10 Years	$	2,214	$	2,538	$	1,299	$	1,458

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 common stocks of small-capitalization companies. Small-capitalization companies are defined as companies that have market capitalizations within the market capitalization range of the companies in the Russell 2000^® Index on the last business day of the month in which its most recent reconstitution was completed. Reconstitution of the index currently is completed in June of each year. On June 30, 2020, the range of the index was $41 million to $12.4 billion.

In selecting stocks, 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.

· Strong or improving cash flows, revenue and earnings growth, or other fundamentals.

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

The Fund’s sub-adviser will generally sell a stock if the stock hits its price target, the company’s fundamentals or competitive position significantly deteriorate, or if a better alternative exists in the marketplace.

The Fund may invest up to 15% of its total assets in non-dollar denominated equity securities of non-U.S. issuers. In addition, the Fund may invest up to 25% of its assets, collectively, in non-dollar denominated equity securities of non-U.S. issuers and in dollar-denominated equity securities of non-U.S. issuers that are either listed on a U.S. stock exchange or represented by depositary receipts that may or may not be sponsored by a domestic bank. Up to 15% of the Fund’s total assets may be invested in equity securities of emerging market issuers.

The Fund may utilize options, futures contracts, options on futures contracts, and forward foreign currency exchange contracts (“derivatives”). 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. 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 or a financial

3

intermediary to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers 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. 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 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. For example, these countries may have more unstable governments than developed countries and their economies may be based on only a few industries. 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. Financial and other reporting by companies and government entities also may be less reliable or difficult to obtain in emerging market 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. From time to time, the Fund may invest a significant portion of its assets in companies in one or more related sectors or industries which would make the Fund more vulnerable to adverse developments affecting such sectors or industries.

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 and different legal, regulatory and tax environments. 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 conditions affecting that country or region.

Health Care Sector Risk—The Fund currently invests a significant portion of its assets in the health care sector, although this may change over time. Health care companies may be affected by government regulations and government health care programs, increases or decreases in the cost of medical products and services, changes in patent and intellectual property rights and product liability claims, among other factors.

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 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.

Small-Cap Company Risk—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, 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.

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*

* The performance of the other share classes will differ due to their different expense structures.

During the ten-year period ended December 31, 2020, the Fund’s highest and lowest quarterly returns were 27.55%
and -31.33%, respectively, for the quarters ended December 31, 2020 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.
