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 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 durations 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 Class		Class R6		Retirement Class		Class W
1 year	$	645	$	51	$	57	$	41	$	66	$	0
3 years	$	795	$	160	$	179	$	128	$	208	$	0
5 years	$	958	$	280	$	313	$	224	$	362	$	0
10 years	$	1,429	$	628	$	701	$	505	$	810	$	0

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 fiscal year ended October 31, 2024, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.

Principal investment strategies

Under normal circumstances, the Fund invests at least 80% of its assets in equity securities. For these purposes, “equity securities” include equity securities of any type, including common stocks; preferred securities; warrants to purchase common stocks and preferred securities; convertible debt securities that are either in the money or immediately convertible into common stocks or preferred securities; common and preferred securities issued by master limited partnerships and real estate investment trusts; depositary receipts; and other securities with equity characteristics. In seeking a favorable long-term total return, the Fund will invest in securities which the Fund’s investment adviser, Teachers Advisors, LLC (“Advisors”), believes have the potential for capital appreciation, dividend income, or both. The Fund focuses on large-cap securities that Advisors believes to be attractively valued, show the potential to appreciate faster than the rest of the market and return cash to shareholders in the form of dividends, stock buy-backs or both. Advisors seeks to construct a portfolio whose weighted average market capitalization is similar to the Fund’s benchmark index, the Standard & Poor’s 500^®Index (the “S&P 500 Index”). For purposes of the

Nuveen Core Equity Fund ■Summary Prospectus     3

80% investment policy, the term "assets" means net assets, plus the amount of any borrowings for investment purposes.

Advisors generally looks for companies that it believes are leaders in their respective industries, with sustainable competitive advantages. Advisors also looks for companies that it believes have management teams that are dedicated to creating shareholder value. The Fund may invest up to 20% of its assets in foreign issuers when Advisors believes these issuers offer more attractive investment opportunities. The Fund may also purchase and sell futures, options, swaps and other equity derivatives to carry out the Fund’s investment strategies.

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:

·Market Risk—The risk that market prices of portfolio investments held by the 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, 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. The Fund currently invests a significant portion of its assets in companies in the information technology sector, although this may change over time.

·Issuer Risk (often called Financial 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.

·Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.

·Mid-Cap Risk—The risk that the 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.

·Style Risk—The risk that use of a particular investing style (such as growth or valueinvesting) 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 the Fund’s portfolio investments.

4     Summary Prospectus■Nuveen Core Equity Fund

·Risks of Growth Investing—Due to their relatively high valuations, growth stocks are typically more volatile than value stocks and may experience a larger decline on a forecast of lower earnings, or a negative event or market development, than would a value stock.

·Active Management Risk—The risk that Advisors’ strategy, investment selection or trading execution may cause the Fund to underperform relative to the benchmark index or mutual funds with similar investment objectives and/or strategies and may not produce the desired results or expected returns.

·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. 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 the Fund’s investments. Economic sanctions and other similar governmental actions or developments could, among other things, effectively restrict or eliminate the Fund’s ability to purchase or sell certain foreign securities or groups of foreign securities, and/or thus may make the 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.

·Derivatives Risk—The risks associated with investing in derivatives, including futures, options, swaps, and other equity derivative instruments, and other similar instruments (referred to collectively as “derivatives”) may be different and greater than the risks associated with directly investing in the underlying securities and other instruments, and include leverage risk, market risk, counterparty risk, liquidity risk, operational risk and legal risk. The Fund may use more complex derivatives that might be particularly susceptible to liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested. Derivatives used for hedging or risk management may not operate as

Nuveen Core Equity Fund ■Summary Prospectus     5

intended, may expose the Fund to other risks, and may be insufficient to protect the Fund from the risks they were intended to hedge.

Please see the non-summary portion of the Prospectus for more detailed information about the risks described above.

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 for the last ten years. 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 I, Premier Class, Retirement Class, Class A and Class W 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 the Fund’s benchmark and broad-based securities market index. 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, reimburse and/or compensate the Fund for certain fees, expenses and/or costs. Without these reductions and/or compensation, 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 benchmark and broad-based securities market index listed below is unmanaged, and you cannot invest directly in an index. The returns for the benchmark index reflect no deduction for fees, expenses or taxes.

For current performance information of each share class, including performance to the most recent month-end, please visit www.nuveen.com/performance or call 800-257-8787.

The after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements such as 401(a), 401(k) or 403(b) plans or Individual Retirement Accounts (IRAs). After-tax returns are shown for only one class, and after-tax returns for other classes will vary.
