#### Example
This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example

2&nbsp;&nbsp;&nbsp;&nbsp; **Summary Prospectus** ■ Nuveen Lifestyle Income Fund

------

assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses, before fee waivers and/or expense reimbursements, remain the same. The example assumes that the Fund's fee waiver and/or expense reimbursement arrangements will each remain in place for the duration noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
|  | **Class A** | **Class I** | **Premier <br>Class** | **Class R6** | **Retirement <br>Class** |
| 1 year | $646 | $55 | $60 | $45 | $70 |
| 3 years | $853 | $229 | $260 | $200 | $277 |
| 5 years | $1076 | $419 | $477 | $368 | $500 |
| 10 years | $1717 | $966 | $1101 | $857 | $1143 |

---

#### Portfolio turnover
The Fund pays transaction costs, such as commissions, as applicable, 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 fiscal year ended May 31, 2025, the Fund's portfolio turnover rate was 16% of the average value of its portfolio.

#### Principal investment strategies
The Fund is a "fund of funds" that invests in Class R6 or Class I shares of other Nuveen mutual funds and in other investment pools or investment products, including other funds or exchange-traded funds ("ETFs") advised by the Fund's investment adviser, Teachers Advisors, LLC ("Advisors"), or its affiliates (collectively, the "Underlying Funds"). The Fund is designed for investors seeking current income with some capital appreciation through a relatively stable asset allocation strategy targeting an income-oriented and conservative risk-return profile. Advisors generally seeks to meet the Fund's investment objective by investing: (1) approximately 20% of the Fund's assets in equity Underlying Funds and (2) approximately 80% of the Fund's assets in fixed-income Underlying Funds. The Fund may deviate from these target allocations by up to ten percentage points depending upon current market conditions and outlook.

The Underlying Funds' allocation targets generally represent targets for investments in equity and fixed-income asset classes. Within the equity and fixed-income asset classes, Advisors allocates the Fund's investments to particular market sectors (which may include U.S. equity, international equity, fixed-income and short-term fixed-income) represented by various Underlying Funds. To maintain an appropriate allocation among the Underlying Funds, the portfolio managers monitor the domestic and foreign equity markets, as well as

Nuveen Lifestyle Income Fund ■ **Summary Prospectus** &nbsp;&nbsp;&nbsp;&nbsp;3

------

overall financial and economic conditions. The Fund may sometimes be more heavily weighted toward equities or fixed-income than the target allocations, if the portfolio managers believe market conditions warrant. For example, the Fund may increase its holdings in fixed-income Underlying Funds in periods when the portfolio managers believe the equity markets will decline. The market sector allocations and Underlying Fund allocations may also be changed over time by the portfolio managers, including the addition and removal of market sectors and Underlying Funds in which the Fund invests in light of the Fund's desired level of risk and potential return at a particular time as evaluated by the portfolio managers based on a mix of qualitative and quantitative factors. The portfolio managers may also opportunistically purchase other Funds or other investment pools or investment products, based on the portfolio managers' evaluation of the market sectors and/or Underlying Funds, without prior notice to shareholders. If 10% or more of the Fund's assets are expected to be invested in any Underlying Fund, market sector or asset class not listed in the chart below, shareholders will receive prior notice of such change.

As a result of its investments in the Underlying Funds, the Fund's returns will reflect investments in a mix of domestic and foreign equities of companies of various sizes and market capitalizations and a variety of domestic and foreign fixed-income instruments of private and governmental issuers of varying maturities and credit qualities.

As part of the Fund's ability to invest in other investment pools or investment products noted above, the Fund may invest in ETFs and exchange-traded notes ("ETNs") to gain exposure to various market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund may use ETFs and ETNs for cash management, hedging or defensive purposes. ETFs and ETNs will be subject to the risks associated with the types of securities or sectors that they track, while ETNs, which are structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, including credit risk.

The Fund's asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector as of June 30, 2025, are listed in the chart below. These allocations may change over time. Underlying Fund allocations in particular may change from year to year. **However, as of the date of this Prospectus, Advisors expects that the allocations among the market sectors and Underlying Funds set forth below will be adjusted over time as Advisors implements: (i) the addition of Nuveen Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity and International Equity market sectors, respectively, and corresponding reductions to other Underlying Funds in those market sectors; and (ii) strategic reallocations among certain Underlying Funds.**

#### Principal investment risks
You could lose money over short or long periods by investing in this Fund. An investment in the Fund, due to the nature of the Fund's portfolio holdings, typically is subject to the following principal investment risks:

&nbsp;&nbsp;&nbsp;&nbsp;· **Asset Allocation Risk**—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.

&nbsp;&nbsp;&nbsp;&nbsp;· **Underlying Funds Risks**—The Fund is exposed to the risks of the Underlying Funds in which it invests in direct proportion to the amount of assets the Fund allocates to each Underlying Fund. Because the Fund targets its investments in a higher percentage of fixed-income Underlying Funds, Fixed-Income Underlying Funds Risks are expected to predominate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· **Fixed-Income Underlying Funds Risks**—The risks of investing in fixed-income Underlying Funds include risks specific to their investment strategies, as well as risks related to the fixed-income markets in general, such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· interest rate risk—The risk that changes in interest rates can adversely affect the value or liquidity of, and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests in longer duration fixed-income investments and during periods when prevailing interest rates are changing. There is a risk that interest rates across the financial system may change, possibly significantly and/or rapidly. In general, changing interest rates,

Nuveen Lifestyle Income Fund ■ **Summary Prospectus** &nbsp;&nbsp;&nbsp;&nbsp;5

------

including rates that fall below zero, or a lack of market participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the values of longer duration fixed-income securities usually change more than the values of shorter duration fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will be less volatile but may provide lower returns than fixed-income securities with longer durations or maturities. Other factors that may affect the value of debt securities include, but are not limited to, economic, political, public health, and other crises and responses by governments and companies to such crises;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· prepayment risk—The risk that, during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· extension risk—The risk that, during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing a Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· issuer risk—The risk that an issuer's earnings prospects, credit rating and overall financial position will deteriorate, causing a decline in the value of the issuer's financial instruments over short or extended periods of time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· credit risk—The risk that the issuer of fixed-income investments may not be able or willing, or may be perceived (whether by market participants, rating agencies, pricing services or otherwise) as not able or willing, to meet interest or principal payments when the payments become due. Actual or perceived changes in economic, social, public health, financial or political conditions in general or that affect a particular type of investment, issuer, guarantor or counterparty can reduce the ability of the party to meet its obligations, which can affect the credit quality, liquidity and/or value of an investment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· credit spread risk—The risk that credit spreads (i.e., the difference in yield between securities that is due to differences in each security's respective credit quality) may increase when market participants believe that bonds generally have a greater risk of default, which could result in a decline in the market values of a Fund's debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· income volatility risk—The risk that the level of current income from a portfolio of fixed-income investments may decline in certain interest rate environments;

6&nbsp;&nbsp;&nbsp;&nbsp; **Summary Prospectus** ■ Nuveen Lifestyle Income Fund

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· market volatility, liquidity and valuation risk (types of market risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for a Fund to properly value its investments and that a Fund may not be able to purchase or sell an investment at an attractive price, if at all;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· fixed-income foreign investment risk—Investment in fixed-income securities or financial instruments of foreign issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments as well as armed conflicts. These developments may impact the ability of a foreign debt issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund's ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. Foreign investments may also have lower overall liquidity and be more difficult to value than investments in U.S. issuers. To the extent a 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. Changes in the value of foreign currencies may make the return on an investment increase or decrease, unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other restrictions by the United States and other governments may also negatively impact a Fund's investments. Economic sanctions and other similar governmental actions or developments could, among other things, effectively restrict or eliminate a Fund's ability to purchase or sell certain foreign securities or groups of foreign securities, and/or thus may make a Fund's investments in such securities less liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures that may be imposed could vary broadly in scope, and their impact is impossible to predict; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· call risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in a Fund's income.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· **Equity Underlying Funds Risks**—The risks of investing in equity Underlying Funds include risks specific to their investment strategies, as well as risks related to the equity markets in general, such as:

Nuveen Lifestyle Income Fund ■ **Summary Prospectus** &nbsp;&nbsp;&nbsp;&nbsp;7

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· market risk—The risk that market prices of portfolio investments held by a Fund may fluctuate rapidly or unpredictably due to a variety of factors, including responses to government actions or interventions, or changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole. Such conditions may add significantly to the risk of volatility in the net asset value ("NAV") of the Fund's shares and adversely affect the Fund and its investments. From time to time, a 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· issuer risk—The risk that an issuer's earnings prospects, credit rating and overall financial position will deteriorate, causing a decline in the value of the issuer's financial instruments over short or extended periods of time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· foreign investment risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments as well as armed conflicts and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent a 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. Changes in the value of foreign currencies may make the return on an investment increase or decrease, unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other restrictions by the United States or other governments may also negatively impact a Fund's investments. Economic sanctions and other similar governmental actions or developments could, among other things, effectively restrict or eliminate a Fund's ability to purchase or sell certain foreign securities or groups of foreign securities, and/or thus may make a Fund's investments in such securities less liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other

------

measures that may be imposed could vary broadly in scope, and their impact is impossible to predict;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· small- and mid-cap risk—The risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies often have lower overall liquidity than securities of larger companies as a result of there being a smaller market for their securities, which can have an adverse effect on the pricing of these securities and on the ability to sell these securities when a Fund's investment adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, more established companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· style risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of a Fund's portfolio investments; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· dividend-paying security risk—The risk that investments in dividend-paying securities could cause a Fund to underperform similar funds that invest without consideration of an issuer's track record of paying dividends.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· **Underlying ETF Risk**—In addition to the same principal risks as an investment in a mutual fund with the same investment objectives, strategies and policies as the ETF, investments in an Underlying Fund that is an ETF are subject to additional risks, including: (i) the market price of the ETF's shares may trade at a premium or a discount to their NAV; (ii) an active trading market for an ETF's shares may not develop or be maintained; and (iii) there is no assurance that the requirements of the exchange necessary to maintain the listing of an ETF will continue to be met or remain unchanged.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· **Emerging Markets Underlying Funds Risk**—The risk of foreign investment often increases in countries with emerging markets or those 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 a Fund's ability to evaluate potential portfolio companies. As a result, there could be less information available about issuers in emerging market countries, which could negatively affect Advisors' ability to evaluate local companies or their

potential impact on a Fund's performance. Because the financial markets of emerging market countries may be very small, share 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 and may be more vulnerable to market manipulation. In addition, foreign investors such as a Fund are subject to a variety of special restrictions in many emerging market countries. Moreover, legal remedies for investors in emerging markets may be more limited, and U.S. authorities may have less ability to enforce certain regulatory or legal obligations or otherwise bring actions against bad actors in emerging market countries.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· **Illiquid Investments Underlying Funds Risk**—The risk that illiquid investments may be difficult to sell for the value at which they are carried, if at all, or at any price within the desired time frame.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· **Currency Underlying Funds Risk**—The risk that foreign (non-U.S.) currencies may decline in value relative to the U.S. dollar and adversely affect the value of a Fund's investments in foreign currencies, securities denominated in foreign currencies or derivative instruments that provide exposure to foreign currencies. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates and the imposition of currency controls or other political, economic and tax developments in the U.S. or abroad.

&nbsp;&nbsp;&nbsp;&nbsp;· **Active Management Risk**—The risk that the strategy, investment selection or trading execution of Advisors or another investment adviser or sub-adviser of an Underlying Fund could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives and/or strategies and may not produce the desired results or expected returns.

&nbsp;&nbsp;&nbsp;&nbsp;· **Fund of Funds Risk**—The ability of the Fund to achieve its investment objective will depend in part upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.

*There can be no assurances that the Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the Prospectus for more detailed information about the risks described above, including the risks of the Underlying Funds.*

#### Past performance
The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. The bar chart shows the annual total returns of Class R6 of the Fund, before taxes, in each full calendar year since inception of Class R6. Because the expenses vary

across share classes, the performance of Class R6 may vary from the other share classes. Below the bar chart are the best and worst returns of Class R6 for a calendar quarter during the full calendar-year periods covered by the bar chart. The performance table following the bar chart shows the Fund's average annual total returns for Class R6, Class A, Class I, Premier and Retirement classes over the applicable one-year, five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund's target allocations. After-tax performance is shown only for Class R6 shares, and after-tax returns for the other classes of shares will vary from the after-tax returns presented for Class R6 shares.

The returns shown below reflect previous agreements by Advisors to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.
