<b>Transamerica Large Growth </b>

<b>Investment Objective:</b>

<b>Example:</b>

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. Only the 1 year dollar amount shown below reflects TAM's agreement to waive fees and/or reimburse fund expenses. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example - Transamerica Large Growth - USD ($)	1 year	3 years	5 years	10 years
Class R	121	378	654	1,443
Class R4	92	298	521	1,162
Class I3	72	224	390	871

<b>Portfolio Turnover:</b>

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 34% of the average value of its portfolio.

<b>Principal Investment Strategies: </b>

The fund normally invests primarily in common stocks of companies that its sub-advisers, Jennison Associates LLC and Wellington Management Company LLP, believe have the potential for above average growth in earnings and dividends. Under normal circumstances, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of large cap companies and other investments with similar economic characteristics. The fund considers large cap 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^® Index¹. As of December 31, 2018, the market capitalization of the smallest company in the Russell 1000^® Index was $472.52 million. The fund emphasizes common and preferred stocks listed on the New York Stock Exchange and other U.S. securities exchanges and, to a lesser extent, equity securities that are listed on foreign securities exchanges and those traded over-the-counter. The fund uses multiple sub-advisers to try to control the volatility often associated with growth funds, but there can be no assurance that this strategy will succeed.

<b>Principal Risks:</b>

Risk is inherent in all investing. Many factors affect the fund's performance. The value of your investment in the fund, as well as the amount of return you receive on your investment, may fluctuate significantly. 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) 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.

Active Trading – The fund may purchase and sell securities without regard to the length of time held. Active trading may have a negative impact on performance by increasing transaction costs and may generate greater amounts of net short-term capital gains, which, for shareholders holding shares in taxable accounts, would generally be subject to tax at ordinary income tax rates upon distribution. During periods of market volatility, active trading may be more pronounced.

Currency – The value of investments in securities denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. Currency conversion costs and currency fluctuations could reduce or eliminate investment gains or add to investment losses. Currency exchange rates can be volatile and may fluctuate significantly over short periods of time, and are affected by factors such as general economic conditions, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation.

Cybersecurity – Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, shareholder data (including private shareholder information), and/or proprietary information, or cause the fund, TAM, a sub-adviser and/or the fund's other service providers (including, but not limited to, fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality. A cybersecurity incident may disrupt the processing of shareholder transactions, impact the fund's ability to calculate its net asset values, and prevent shareholders from redeeming their shares.

Depositary Receipts – Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. 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. Such restrictions may cause equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

Equity Securities – Equity securities represent an ownership interest in an issuer, rank junior in a company’s capital structure and consequently may entail greater risk of loss than debt securities. Equity securities include common and preferred stocks. Stock markets are volatile and the value of equity securities may go up or down sometimes rapidly and unpredictably. Equity securities may have greater price volatility than other asset classes, such as fixed income securities. The value of equity securities fluctuates based on changes in a company’s financial condition and overall market and economic conditions. If the market prices of the equity securities owned by the fund fall, the value of your investment in the fund will decline. If the fund holds equity securities in a company that becomes insolvent, the fund’s interests in the company will rank junior in priority to the interests of debtholders and general creditors of the company.

Foreign Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries in which the fund may invest may have markets that are less liquid, less regulated, less transparent and more volatile than U.S. markets. The value of the fund’s investments may decline 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, political or financial instability or other adverse economic or political developments. Lack of information and weaker accounting standards also may affect the value of these securities.

Growth Stocks – Returns on growth stocks may not move in tandem with returns on other categories of stocks or the market as a whole. Growth stocks typically are particularly sensitive to market movements because their market prices tend to reflect future expectations. When it appears those expectations may not be met, the prices of growth securities typically fall. Growth 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 “value” stocks.

Legal and Regulatory – Legal and regulatory changes could occur that may adversely affect the fund, its investments, and its ability to pursue its investment strategies and/or increase the costs of implementing such strategies. New or revised laws or regulations may be imposed by the U.S. Securities and Exchange Commission, the U.S. Commodity Futures Trading Commission, the Internal Revenue Service, the U.S. Federal Reserve or other governmental regulatory authorities or self-regulatory organizations that could adversely affect the fund. The fund also may be adversely affected by changes in the enforcement or interpretation of existing statutes and rules by governmental regulatory authorities or self-regulatory organizations.

Management – The fund is subject to the risk that the investment manager’s or sub-adviser’s judgments and decisions may be incorrect or otherwise may not produce the desired results, causing the value of your investment to go down. The fund 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. In addition, the fund’s investment strategies or policies may change from time to time. Those changes may not lead to the results intended by the investment manager or sub-adviser and could have an adverse effect on the value or performance of the fund. Any of these things could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives.

Market – The value of the fund's securities may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates or currency rates, lack of liquidity in the markets or adverse investor sentiment. Adverse market conditions may be prolonged and may not have the same impact on all types of securities. The value of securities also may go down due to events or conditions that affect particular sectors, industries or issuers. If the value of the securities owned by the fund fall, the value of your investment will go down. The fund may experience a substantial or complete loss on any individual security.

In the past decade, financial markets throughout the world have experienced increased volatility, depressed valuations, decreased liquidity and heightened uncertainty. Governmental and non-governmental issuers have defaulted on, or been forced to restructure, their debts. These market conditions may continue, worsen or spread. Events that have contributed to these market conditions include, but are not limited to, major cybersecurity events; geopolitical events (including wars and terror attacks); measures to address budget deficits; downgrading of sovereign debt; declines in oil and commodity prices; dramatic changes in currency exchange rates; and public sentiment. The European Union has experienced increasing stress for a variety of reasons, including economic downturns in various member countries. In June 2016, the United Kingdom voted to withdraw from the European Union, and additional members could do the same. The impact of these conditions and events is not yet known.

There has been significant U.S. and non-U.S. government and central bank intervention in and support of financial markets during the past decade. The Federal Reserve has reduced and begun unwinding its market support activities and has begun raising interest rates. Certain foreign governments and central banks are implementing so-called negative interest rates (e.g., charging depositors who keep their cash at a bank) to spur economic growth. Further Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including interest rate increases, unwinding of quantitative easing, or contrary actions by different governments, may not work as intended, could negatively affect financial markets generally, increase market volatility, and reduce the value and liquidity of securities in which the fund invests.

Policy and legislative changes in the United States and in other countries are affecting many aspects of financial regulation, and may in some instances contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time.

Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, terrorism, natural disasters and other circumstances in one country or region could 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 be negatively affected.

Preferred Stock – Preferred stock’s right to dividends and liquidation proceeds is junior to the rights of a company’s debt securities. The value of preferred stock may be subject to factors that affect fixed income and equity securities, including changes in interest rates and in a company’s creditworthiness. The value of preferred stock tends to vary more with fluctuations in the underlying common stock and less with fluctuations in interest rates and tends to exhibit greater volatility. Shareholders of preferred stock may suffer a loss of value if dividends are not paid and have limited voting rights.

Small and Medium Capitalization Companies – The fund will be exposed to additional risks as a result of its investments in the securities of small or medium capitalization companies. Small or medium capitalization companies may be more at risk than large capitalization companies because, among other things, they may have limited product lines, operating history, market or financial resources, or because they may depend on a limited management group. The prices of securities of small and medium capitalization companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large capitalization companies by changes in earnings results and investor expectations or poor economic or market conditions. Securities of small and medium capitalization companies may underperform large capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.

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. They do not represent any rights in the assets of the issuing company, and cease to have value if not exercised prior to the expiration date.

<b>Performance:</b>

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 table shows how the fund’s average annual total returns for different periods compare to the returns of a broad measure of market performance, as well as a secondary index.

The fund acquired the assets and assumed the liabilities of three Transamerica Partners funds, including Transamerica Partners Institutional Large Growth (the “predecessor fund”), on March 10, 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, 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 reorganization, 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 have been lower.

In the “10 Years or Since Inception” column of the table, returns are shown for ten years or since inception of the share class, whichever is less. Index returns are for ten years.

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/individual/products/mutual-funds/performance/ or by calling 1-888-233-4339.

The after-tax returns are calculated using the historic highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns may depend on the investor’s individual tax situation and may differ from those shown. After-tax returns may not be relevant if the investment is made through a tax-exempt or tax-deferred account, such as a 401(k) plan.

[1] Contractual arrangements have been made with the fund’s investment manager, Transamerica Asset Management, Inc. (“TAM”), through March 1, 2020 to waive fees and/or reimburse fund expenses to the extent that total annual fund operating expenses exceed 1.25% for Class R shares, 0.90% for Class R4 shares and 0.75% for Class I3 shares, excluding, as applicable, acquired fund fees and expenses, interest, taxes, brokerage commissions, dividend and interest expenses on securities sold short, extraordinary expenses and other expenses not incurred in the ordinary course of the fund’s business. These arrangements cannot be terminated prior to March 1, 2020 without the Board of Trustees’ consent. TAM is permitted to recapture amounts waived and/or reimbursed to a class during any of the 36 months from the date on which TAM waived fees and/or reimbursed expenses for the class. A class may reimburse TAM only if such reimbursement does not cause, on any particular business day of the fund, the class’s total annual operating expenses (after the reimbursement is taken into account) to exceed the applicable limits described above or any other lower limit then in effect.
