Investment Objective: Seeks to maximize total return.

Fees and Expenses: This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Shareholder Fees (fees paid directly from your investment)

Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	None
Maximum deferred sales charge (load) (as a percentage of purchase price or redemption proceeds, whichever is lower)	None

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

Management fees1	0.77%
Distribution and service (12b-1) fees	None
Other expenses	0.05%
Total annual fund operating expenses	0.82%

Management fees have been restated to reflect a reduction in management fees effective August 1, 2022.

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. 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 I2	$84	$262	$455	$1,014

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 53% of the average value of its portfolio.

Principal Investment Strategies: The fund’s sub-advisers, Systematic Financial Management, L.P. and Thompson, Siegel & Walmsley LLC (the “sub-advisers”), seek to achieve the fund’s objective by investing, under normal circumstances, at least 80% of the fund’s net assets (plus the amount of borrowings, if any, for investment purposes) in small- and mid-cap equity securities (U.S. equity securities, American Depositary Receipts (“ADRs”) and foreign securities trading on U.S. markets).

The fund defines small- and mid-cap equities as companies whose market capitalization falls within the range of securities comprising the Russell 2000® Index1 and the Russell Midcap® Index respectively, or within the range of the Russell 2500® Index, whichever is broader at the time of purchase. Over time, the capitalizations of the companies in the index will change. As they do, the size of the companies in which the fund invests may change. As of December 31, 2021, the market capitalization range of securities comprising the Russell 2000® Index was between $32 million and $13.96 billion, the market capitalization range of securities comprising the Russell Midcap® Index was between $435 million and $73.63 billion, and the market capitalization range of securities comprising the Russell 2500® Index was between $32 million and $35.32 billion.

The fund’s investment manager, Transamerica Asset Management, Inc., determines the allocation of the fund’s assets between the fund’s sub-advisers and rebalances the allocation periodically to normally maintain an approximate allocation of 60% of the fund’s assets to Thompson, Siegel & Walmsley LLC and 40% of the fund’s assets to Systematic Financial Management, L.P. The fund emphasizes investments in common stocks.

Thompson, Siegel & Walmsley LLC is the sub-adviser for the mid cap sleeve. In the mid-cap sleeve, the sub-adviser seeks to invest in companies it believes present a value or potential worth that is not recognized by prevailing market prices or that have experienced some fundamental changes and are intrinsically undervalued by the investment community. The sub-adviser’s mid-cap value process uses a combination of quantitative and qualitative methods and is based on a four-factor valuation screen. Factors one and two of the screen attempt to assess a company’s discount to private

market value relative to other mid-cap stocks. The third factor considers the relative earnings prospects of the company. The fourth factor involves looking at the company’s recent price action.

Systematic Financial Management, L.P. is the sub-adviser for the small-cap sleeve. In the small-cap sleeve, the sub-adviser generally will invest in common stocks of companies with small capitalizations that are attractively valued and possess low price cash flow ratios or, in the case of certain financial stocks, low price/earnings ratios and/or low price/book ratios. The sub-adviser’s security selection process generally favors companies with strong operating cash flow, strong free cash flow, limited financial leverage and strong debt coverage. Trends in balance sheet items including inventories, accounts receivable, and payables are scrutinized as well. The sub-adviser also reviews the company’s products/services, market position, industry condition, financial and accounting policies and quality of management.

The fund’s investment methodology unifies what both sub-advisers deem to be the best attributes of quantitative screening and fundamental research in an integrated and repeatable process designed to outperform the Russell 2500® Value Index over the long term. Under normal market conditions, cash and cash equivalents are generally less than 5% of the portfolio 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.

The fund may invest up to 10% of its total assets in the securities of foreign issuers, including ADRs and foreign securities trading on U.S. markets. The fund may also invest in real estate investment trusts (“REITs”), and may invest up to 5% of its total net assets in exchange traded funds (“ETFs”).

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. 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 general market conditions, overall economic trends or 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 or other factors, political developments, investor sentiment, the global and domestic effects of a pandemic, and other factors that may or may not be related to the issuer of the security or other asset. If the market prices of the fund’s securities and assets fall, the value of your investment will go down.

Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, public health events (such as the spread of infectious disease), wars, terrorism, cybersecurity events, technology and data interruptions, natural disasters, and other 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 pandemic of the novel coronavirus respiratory disease designated COVID-19 has resulted in extreme volatility in the financial markets, a domestic and global economic downturn, severe losses, particularly to some sectors of the economy and individual issuers, and reduced liquidity of many instruments. There also have been significant disruptions to business operations, including business closures; strained healthcare systems; disruptions to supply chains and employee availability; large fluctuations in consumer demand; and widespread uncertainty regarding the duration and long-term effects of the pandemic. The domestic and global economic downturn may be prolonged. The pandemic may result in domestic and foreign political and social instability, damage to diplomatic and international trade relations, and continued volatility and/or decreased liquidity in the securities markets. Developing or emerging market countries may be more impacted by the pandemic.

The U.S. government and the Federal Reserve, as well as certain foreign governments and central banks, have taken extraordinary actions to support local and global economies and the financial markets in response to the COVID-19 pandemic, including by pushing interest rates to very low levels. This and other government intervention into the economy and financial markets to address the pandemic may not work as intended, particularly if the efforts are perceived by investors as being unlikely to achieve the desired results. Government actions to mitigate the economic impact of the pandemic have resulted in large expansion of government deficits and debt, the long-term consequences of which are not known. Rates of inflation have recently risen, which could adversely affect economies and markets.

The COVID-19 pandemic could continue to adversely affect the value and liquidity of the fund’s investments, impair the fund’s ability to satisfy redemption requests, and negatively impact the fund’s performance. In addition, the pandemic, and measures taken to mitigate its effects, could result in disruptions to the services provided to the fund by its service providers.

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.

Small Capitalization Companies – The fund will be exposed to additional risks as a result of its investments in the securities of small capitalization companies. Small capitalization companies may be more at risk than larger capitalization companies because,

among other things, they may have limited product lines, operating history, market or financial resources, or because they may depend on limited management groups. Securities of small capitalization companies are generally more volatile than and may underperform larger capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.

Medium Capitalization Companies – The fund will be exposed to additional risks as a result of its investments in the securities of medium capitalization companies. Investing in medium capitalization companies involves greater risk than is customarily associated with more established companies. The prices of securities of medium capitalization companies generally are more volatile and are more likely to be adversely affected by changes in earnings results and investor expectations or poor economic or market conditions. Securities of medium capitalization companies may underperform larger capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.

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 value of equity securities fluctuates based on real or perceived changes in a company’s financial condition, factors affecting a particular industry or industries, and overall market, economic and political conditions. 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.

Liquidity – The fund may make investments that are illiquid or that become illiquid after purchase. Illiquid investments can be difficult to value, may trade at a discount from comparable, more liquid investments, and may be subject to wide fluctuations in value. If the fund is forced to sell an illiquid investment to meet redemption requests or other cash needs, the fund may be forced to sell at a substantial loss or may not be able to sell at all. Liquidity of particular investments, or even entire asset classes, including U.S. Treasury securities, can deteriorate rapidly, particularly during times of market turmoil, and those investments may be difficult or impossible for the fund to sell. This may prevent the fund from limiting losses.

Valuation – 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 that use matrix or evaluated pricing systems, 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.

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 purchase and sell securities without regard to the length of time held. Active trading may be more pronounced during periods of market volatility , may have a negative impact on performance and may generate greater amounts of short-term capital gains.

Counterparty – The fund could lose money if the counterparties to derivatives, repurchase agreements and other financial contracts entered into for the fund do not fulfill their contractual obligations. In addition, the fund may incur costs and may be hindered or delayed in enforcing its rights against a counterparty.

Currency – The value of a fund’s investments in securities denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk. Currency exchange rates can be volatile and may fluctuate significantly over short periods of time. Currency conversion costs and currency fluctuations could reduce or eliminate investment gains or add to investment losses. A fund may be unable or may choose not to hedge its foreign currency exposure.

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. 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.

Foreign Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risks. Foreign markets can be less liquid, less regulated, less transparent and more volatile than U.S. markets. The value of the fund’s foreign investments may decline, sometimes rapidly or unpredictably, because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable or unsuccessful government actions, reduction of government or central bank support, tariffs and trade disruptions, sanctions, political or financial instability, social unrest or other adverse economic or political developments. Foreign investments may also be subject to different accounting practices and different regulatory, legal, auditing, financial reporting and recordkeeping standards and practices, and may be more difficult to value than investments in U.S. issuers.

Large Shareholder – A significant portion of the fund’s shares may be owned by other funds sponsored by Transamerica. Transactions by these funds 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 income to shareholders if such sales of investments resulted in gains. In addition, sizeable redemptions could cause the fund’s total expenses to increase.

REITs – Investing in real estate investment trusts (“REITs”) involves unique risks. When the fund invests in REITs, it is subject to risks generally associated with investing in real estate. A REIT’s performance depends on the types and locations of the properties it owns, how well it manages those properties and cash flow. REITs may have limited financial resources, may trade less frequently and in limited volume, may engage in dilutive offerings, and may be subject to more abrupt or erratic price movements than the overall securities markets. In addition to its own expenses, the fund will indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests. U.S. REITs are subject to a number of highly technical tax-related rules and requirements; and a U.S. REIT’s failure to qualify for the favorable U.S. federal income tax treatment generally available to U.S. REITs could result in corporate-level taxation, significantly reducing the return on an investment to the fund.

Repurchase Agreements – In a repurchase agreement, the fund purchases securities from a broker-dealer or a bank, called the counterparty, upon the agreement of the counterparty to repurchase the securities from the fund at a later date, and at a specified price. The securities purchased serve as the fund's collateral for the obligation of the counterparty to repurchase the securities. If the counterparty does not repurchase the securities, the fund is entitled to sell the securities, but the fund may not be able to sell them for the price at which they were purchased, thus causing a loss. If the counterparty becomes insolvent, there is some risk that the fund will not have a right to the securities, or the immediate right to sell the securities.

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. In addition, the fund will bear a pro rata portion of the operating expenses of the underlying ETFs in which it invests.

Tax Information: Fund distributions may be taxable as ordinary income, qualified dividend income, or capital gains, except when your investment is in an IRA, 401(k) or other tax-advantaged investment plan. In that case, you may be taxed when you take a distribution from such plan, depending on the type of plan, the circumstances of your distribution and other factors.

Payments to Broker-Dealers and Other Financial Intermediaries: If you purchase the fund through a broker-dealer or other financial intermediary, the fund and/or its affiliates 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 intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
