Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 

Class:	R4	R	I3
Management fees	0.45%	0.45%	0.45%
Distribution and service (12b-1) fees	0.25%	0.50%	None

Example: This 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 redeem all 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 remain the same. The Example reflects applicable waivers and/or reimbursements for the duration of such arrangement(s). Although your actual costs may be higher or lower, based on these assumptions your costs would be: 

	1 year	3 years	5 years	10 years
Class R4	$77	$244	$426	$952
Class R	$102	$321	$557	$1,235
Class I3	$53	$167	$291	$653

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 portfolio turnover rate for the fund was 123% of the average value of its portfolio.

Principal Investment Strategies: The fund normally invests primarily in issuers listed on U.S. exchanges with a focus on value stocks. Under normal circumstances, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in securities of large-cap value companies and other investments with similar economic characteristics. The fund

considers large-cap value companies to be companies with market capitalizations that, at the time of initial purchase, exceed the market capitalization of the smallest company included in the Russell 1000® Value Index. As of June 30, 2026, the market capitalization of the smallest company in the Russell 1000® Value Index was approximately $2.26 billion.

The fund's sub-adviser, PineBridge Investments LLC (the "sub-adviser"), employs a process that categorizes companies according to where the sub-adviser believes they reside in their respective company life cycles, and then lets the categorization drive how the companies are analyzed for investment attractiveness. Through a quantitative framework, the sub-adviser ranks companies within what are considered fundamentally similar groups of stocks based on six life-cycle stages (three types for growth companies and three for mature companies). After quantitatively categorizing each company in the investment universe into their six main life-cycle categorizations, the sub-adviser's alpha model then quantitatively assesses the attractiveness of each company based on numerous factors that are relevant to each life-cycle category. The model generates a numerical ranking based on this quantitative categorization and factor-based assessment, which indicates the attractiveness of each stock. An optimization process is then used by the sub-adviser to build the fund's portfolio using constraints relative to the fund's primary benchmark. Final stock selection and portfolio positioning are subject to the discretion of the fund's portfolio management team.

The equity securities in which the fund may invest include, but are not limited to, common stocks, depository receipts, preferred stocks and securities convertible into common stocks (such as warrants and rights). The fund may also invest up to 5% of its assets in index exchange-traded funds ("ETFs"). Value stocks as a group may be out of favor and underperform the overall equity market for a long period of time, for example, while the market favors "growth" stocks.

Additionally, the fund may also invest its assets in cash, cash equivalent securities or other short-term debt securities, money market funds and U.S. government securities.

Principal Risks: Risk is inherent in all investing. Many factors and risks affect the fund's performance, including those described below. The value of your investment in the fund, as well as the amount of return you receive on your investment, may fluctuate significantly day to day and over time. You may lose part or all of your investment in the fund or your investment may not perform as well as other similar investments. The following is a summary description of principal risks (in alphabetical order after certain key risks) of investing in the fund. The relative significance of the key risks below may change over time and you should review each risk factor carefully. An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You may lose money if you invest in this fund.

Market - The market prices of the fund's securities or other assets may go up or down, sometimes rapidly or unpredictably, due to factors such as economic events, inflation, changes in interest rates, governmental actions or interventions, actions taken by the

U.S. Federal Reserve or foreign central banks, market disruptions caused by tariffs, trade disputes, labor strikes, supply chain disruptions or other factors, government shutdowns, political developments, civil unrest, acts of terrorism, armed conflicts, economic sanctions, countermeasures in response to sanctions, cybersecurity events, technological developments (such as artificial intelligence and machine learning), investor sentiment, the global and domestic effects of widespread or local health, weather or climate events, and other factors that may or may not be related to the issuer of the security or other asset. The market price of a security may also fall due to specific conditions that affect a particular sector of the securities market, a particular industry or a particular issuer or group of issuers. To the extent that securities of certain issuers behave or are perceived to behave similarly to each other, the market prices of those securities (or the market as a whole) may fall in response to a decline in the price of a particular security or group of securities. If the market prices of the fund's securities and assets fall, the value of your investment in the fund could go down.

Economies and financial markets throughout the world are increasingly interconnected. Events or circumstances in one or more countries or regions could be highly disruptive to, and have profound impacts on, global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the fund's investments may go down.

The long-term consequences to the U.S. economy of the continued expansion of U.S. government debt and deficits are not known. Also, raising the ceiling on U.S. government debt and periodic legislation to fund the government have become increasingly politicized. Any failure to do either could lead to a default on U.S. government obligations, with unpredictable consequences for the fund's investments, and generally for economies and markets in the U.S. and elsewhere.

Value Investing - The prices of securities the sub-adviser believes are undervalued may not appreciate as anticipated or may go down. The value approach to investing involves the risk that stocks may remain undervalued, undervaluation may become more severe, or perceived undervaluation may actually represent intrinsic value. Value stocks as a group may be out of favor and underperform the overall equity market for a long period of time, for example, while the market favors "growth" stocks.

Model and Data - If quantitative models, algorithms or calculations (whether proprietary and developed by the sub-adviser or supplied by third parties) ("Models") or information or data supplied by third parties ("Data") prove to be incorrect or incomplete, any decisions made, in whole or part, in reliance thereon expose the fund to additional risks. Models can be predictive in nature. The use of predictive Models has inherent risks. The success of relying on or otherwise using Models depends on a number of factors, including the validity, accuracy and completeness of the Model's development, implementation and maintenance, the Model's assumptions, factors, algorithms and methodologies, and the accuracy and reliability of the supplied historical or other Data. Models rely on, among other things, correct and complete Data inputs. If incorrect Data is entered into even a well-founded Model, the resulting information will be incorrect. However, even if Data is input correctly, Model prices may differ substantially from market

prices, especially for securities with complex characteristics. Investments selected with the use of Models may perform differently than expected as a result of the design of the Model, inputs into the Model or other factors. There also can be no assurance that the use of Models will result in effective investment decisions for the fund.

Equity Securities - Equity securities generally have greater risk of loss than debt securities. Stock markets are volatile and the value of equity securities may go up or down, sometimes rapidly and unpredictably. The market price of an equity security may fluctuate based on overall market conditions, such as real or perceived adverse economic or political conditions or trends, tariffs and trade disruptions, wars, social unrest, inflation, substantial economic downturn or recession, changes in interest rates, or adverse investor sentiment. The market price of an equity security also may fluctuate based on real or perceived factors affecting a particular industry or industries or the company itself. If the market prices of the equity securities owned by the fund fall, the value of your investment in the fund will decline. The fund may lose its entire investment in the equity securities of an issuer. A change in financial condition or other event affecting a single issuer may adversely impact securities markets as a whole.

Large Capitalization Companies - The fund's investments in larger, more established companies may underperform other segments of the market because they may be less responsive to competitive challenges and opportunities and unable to attain high growth rates during periods of economic expansion.

Management - The value of your investment may go down if the investment manager's or sub-adviser's judgments and decisions are incorrect or otherwise do not produce the desired results, or if the investment strategy does not work as intended. You may also suffer losses if there are imperfections, errors or limitations in the quantitative, analytic or other tools, resources, information and data used, investment techniques applied, or the analyses employed or relied on, by the investment manager or sub-adviser, if such tools, resources, information or data are used incorrectly or otherwise do not work as intended, or if the investment manager's or sub-adviser's investment style is out of favor or otherwise fails to produce the desired results. Any of these things could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives.

Active Trading - The fund may engage in active trading of its portfolio. Active trading will increase transaction costs and could detract from performance. Active trading may be more pronounced during periods of market volatility and may generate greater amounts of short-term capital gains.

Convertible Securities - Convertible securities are subject to risks associated with both fixed-income and equity securities. For example, if market interest rates rise, the value of a convertible security typically falls. In addition, a convertible security is subject to the risk that the issuer will not be able to pay interest or dividends when due, and the market value of the security may change based on the issuer's actual or perceived creditworthiness. Since the convertible security derives a portion of its value from the underlying common stock, the security is also subject to the same types of market and issuer-specific risks that apply to the underlying common stock. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality.

Cybersecurity - Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to fund assets, fund or shareholder data (including private shareholder information), or proprietary information, cause the fund or its service providers (including, but not limited to, the fund's investment manager, any sub-adviser(s), transfer agent, distributor, custodian, fund accounting agent and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares, receiving distributions or receiving timely information regarding the fund or their investment in the fund. Cybersecurity incidents may render records of fund assets and transactions, shareholder ownership of fund shares, and other data integral to the functioning of the fund inaccessible, inaccurate or incomplete. The use of artificial intelligence and machine learning could exacerbate these risks. Cybersecurity incidents may result in financial losses to the fund and its shareholders, and substantial costs may be incurred in order to prevent or mitigate any future cybersecurity incidents.

Depositary Receipts - Depositary receipts are generally subject to the same risks as are the foreign securities that they evidence or into which they may be converted, and they may be less liquid than the underlying shares in their primary trading market. In addition, depositary receipts expose the fund to risk associated with the non-uniform terms that apply to depositary receipt programs, credit exposure to the depositary bank and to the sponsors and other parties with whom the depositary bank establishes the programs. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert equity shares into depositary receipts and vice versa.

Large Shareholder - A significant portion of the fund's shares may be owned by one or more investment vehicles or institutional investors. Transactions by these large shareholders may be disruptive to the management of the fund. For example, the fund may experience large redemptions and could be required to sell securities at a time when it may not otherwise desire to do so. Such transactions may increase the fund's brokerage and/or other transaction costs. These transactions may also accelerate the realization of taxable capital gains to shareholders. In addition, sizeable redemptions could cause the fund's total expenses to increase.

Money Market Funds - An investment in a money market fund is not a bank account, and is not insured or guaranteed by the Federal Deposit Insurance Corporation ("FDIC") or any other government agency. A money market fund's sponsor is not required to reimburse the fund for losses or to provide financial support to the fund. Although many money market funds seek to maintain a stable net asset value of $1.00 per share, it is possible to lose money by investing in such money market funds. Certain other money market funds float their net asset value.

Preferred Stock - Preferred stocks may pay fixed or adjustable rates of return. Preferred stocks are subject to issuer-specific and market risks applicable generally to equity securities, but also risks associated with fixed-income securities, such as interest rate risk. A company's preferred stocks generally pay dividends only after the company makes required payments to creditors, including holders of its bonds and other debt. As a result, the market prices

of preferred stocks are typically more sensitive to changes in the issuer's creditworthiness than are the prices of debt securities. The market value of preferred stocks generally decreases when interest rates rise.

Sector Focus - To the extent the fund invests more heavily in a particular market sector, the value of the fund's shares will be especially sensitive to developments that significantly affect that sector and there is increased risk that the fund will lose significant value if conditions adversely affect that sector. Individual sectors may be more volatile, and may perform differently, from the broader market.

Underlying Exchange-Traded Funds - To the extent the fund invests its assets in underlying ETFs, its ability to achieve its investment objective will depend in part on the performance of the underlying ETFs in which it invests. Investing in underlying ETFs subjects the fund to the risks of investing in the underlying securities or assets held by those ETFs. Each of the underlying ETFs in which the fund may invest has its own investment risks, and those risks can affect the value of the underlying ETFs' shares and therefore the value of the fund's investments. There can be no assurance that the investment objective of any underlying ETF will be achieved. To the extent that the fund invests more of its assets in one underlying ETF than in another, the fund will have greater exposure to the risks of that underlying ETF. In addition, the fund will bear a pro rata portion of the operating expenses of the underlying ETFs in which it invests.

U.S. Government Securities - U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities backed by the Treasury or the full faith and credit of the U.S. government are guaranteed only as to the timely payment of interest and principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates and the financial condition or credit rating of the U.S. government. Notwithstanding that these securities are backed by the full faith and credit of the U.S. government, circumstances could arise that would prevent the payment of interest or principal. Securities issued by U.S. government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government are not funded by congressional appropriations and the securities issued by them are neither issued nor guaranteed by the U.S. government.

Valuation - Certain investments may be more difficult to value than other types of investments. The sales price the fund could receive for any particular portfolio investment may differ from the fund's valuation of the investment, particularly for securities that trade in thin or volatile markets, that are priced based upon valuations provided by third party pricing services, or that are valued using a fair value methodology. These differences may increase significantly and affect fund investments more broadly during periods of market volatility. Investors who purchase or redeem fund shares on days when the fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the fund had not fair-valued securities or had used a different valuation methodology. The fund's ability to value its investments may also be impacted by technological issues and/or errors by pricing services or other third party service providers. Fair value pricing involves subjective judgment, which may prove to be incorrect.

Warrants and Rights - Warrants and rights may be considered more speculative than certain other types of investments because they do not entitle a holder to the dividends or voting rights for the securities that may be purchased, and they do not represent any rights in the assets of the issuing company. If the price of the stock to which the warrant or right relates does not rise above the exercise price or the warrant or right otherwise is not exercised before the expiration date, it generally expires without any value and the fund will lose any amount it paid for the warrant or right.

Performance: The bar chart and the table below provide some indication of the risks of investing in the fund. The bar chart shows how the fund's performance has varied from year to year. The first index in the table shows how the fund's average annual total returns for different periods compare to the returns of a broad measure of market performance. One or more secondary indices that the manager believes more closely reflect the market sectors and/or types of investments in which the fund invests also are used to measure the fund's performance.

The fund acquired the assets and assumed the liabilities of three Transamerica Partners funds, including Transamerica Partners Institutional Large Value (the "predecessor fund"), on May 5, 2017, and the predecessor fund was the accounting and performance survivor of the reorganizations. This means that the predecessor fund's financial and performance history became the financial and performance history of the fund. In the reorganization of the predecessor fund, former shareholders of the predecessor fund received Class R4 shares of the fund. The performance of Class R4 shares includes the performance of the predecessor fund prior to the reorganizations, and has not been restated to reflect the annual operating expenses of Class R4 shares.

Absent any applicable fee waivers and/or expense limitations, performance would be lower.

As with all mutual funds, past performance (before and after taxes) is not a prediction of future results. Updated performance information is available on our website at www.transamerica.com/investments-fund-center or by calling 1-888-233-4339.

Prior to September 1, 2018, the fund had a different sub-adviser, a different investment objective and used different investment strategies. The performance set forth prior to that date is attributable to the previous sub-adviser.
