Transamerica Concentrated Growth

Summary Prospectus March 1, 2016

Class I2 Ticker Symbol: None

Thank you for being a valued Transamerica shareholder. This Summary Prospectus will provide you with updated information about your investment in the fund.

Before you invest, you may want to review the fund’s prospectus, which contains more information about the fund and its risks. You can find the fund’s prospectus and other information about the fund, including the fund’s statement of additional information and most recent reports to shareholders, online at www.transamerica.com. You can also get this information at no cost by calling 866-414-6349 or by sending an e-mail request to orders@mysummaryprospectus.com, or from your financial professional. The fund’s prospectus and statement of additional information, both dated March 1, 2016, as supplemented from time to time, and the independent registered public accounting firm’s report and financial statements in the fund’s annual report to shareholders, dated October 31, 2015, are incorporated by reference into this summary prospectus.

Investment Objective: Seeks to achieve long-term growth of capital.

Fees and Expenses: This table describes the fees and expenses that you may pay if you buy and hold shares of the fund.

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	0.68%
Distribution and service (12b-1) fees	None
Other expenses1	0.05%
Total annual fund operating expenses	0.73%

1 Management fees have been restated to reflect the combination of investment advisory and administrative services fees under one agreement providing for a single management fee. As a result, “Other expenses” do not include administrative services fees. Prior to March 1, 2016, the fund paid investment advisory fees of 0.65% and administrative services fees of 0.03%.

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
$75	$233	$406	$906

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 34% of the average value of its portfolio.

Principal Investment Strategies: Under normal circumstances, the fund’s sub-adviser, Torray LLC (the “sub-adviser”), will invest at least 80% of the fund’s net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of large capitalization companies with proven records of increasing earnings on a consistent and sustainable basis. The fund considers large capitalization companies to be those companies with market capitalizations of $5 billion or more at the time of purchase. Sustainable growth is a product of businesses generally characterized by durable competitive advantages, high returns on and efficient use of capital, low financial and operating volatility, high levels of recurring revenue and low exposure to cyclical trends. Companies are reviewed on a fundamental basis in the context of long-term secular themes.

The fund employs a concentrated approach, investing in 25 to 30 stocks, with a long-term orientation and a quality focus. Correlation of securities and underlying businesses is considered in an effort to minimize risk within the fund. Initial positions range from 2% to 3% of assets and may be increased over time to between 5% and 7%. Individual positions will not exceed 7%. Sector weights are independent of benchmarks, ranging from 0% to 35%, and cash is not employed in a tactical or strategic manner.

Risk control is an integral part of the sub-adviser’s process. In the context of security selection, the focus is on quality, which is defined as businesses demonstrating consistent financial and operating metrics through a full business cycle, high returns on capital, appropriate leverage and reasonable valuation. Risk control is also a primary part of portfolio construction. In order to achieve effective diversification, correlation among existing and prospective holdings is measured through multiple periods, assigning preference to issues exhibiting low correlation to the portfolio and among sectors. Excess (positive or negative) relative performance also initiates a review of a security by the sub-adviser.

Positions are reduced or sold if they exhibit excess valuation, reach sector or position limits, show increased business volatility, are replaced by higher conviction ideas or fail to fulfill the original investment thesis.

Principal Risks: 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. You may lose money if you invest in this fund.

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. The price 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.

Focused Investing – To the extent the fund invests in a limited number of countries, regions, sectors or industries, or in a limited number of issuers, the fund will be more susceptible to negative events affecting those countries, regions, sectors, industries or issuers, and the value of its shares may be more volatile than if it invested more widely. Local events, such as political upheaval, financial troubles, or natural disasters may disrupt a country’s or region’s securities markets. Geographic risk is especially high in emerging markets.

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 may be particularly susceptible to larger price swings or to adverse developments. 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. Certain changes have already been proposed and additional changes are expected. 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.

Manager – The fund is subject to the risk that the sub-adviser’s judgments and investment decisions, as well as the methods, tools, resources, information and data, and the analyses employed or relied on by the sub-adviser to make those judgments and decisions may be incorrect or otherwise may not produce the desired results. This could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives.

Market – The market prices 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. Market prices of securities also may go down due to events or conditions that affect particular sectors, industries or issuers. When market prices 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 several years, financial markets, such as those in the United States, Europe, Asia and elsewhere, have experienced increased volatility, depressed valuations, decreased liquidity and heightened uncertainty. Governmental and non-governmental issuers defaulted on, or were forced to restructure, their debts. These market conditions may continue, worsen or spread.

The U.S. government and the Federal Reserve, as well as certain foreign governments and central banks have taken steps to support financial markets, including keeping interest rates at historically low levels. This and other government intervention may not work as intended, particularly if the efforts are perceived by investors as being unlikely to achieve the desired results. The Federal Reserve recently has reduced its market support activities. Further reduction or withdrawal of Federal Reserve or other U.S. or non-U.S. governmental or central bank support, including interest rate increases, 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 becoming increasingly interconnected. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, the value and liquidity of the fund's investments may be negatively affected.

Portfolio Management – The value of your investment may decrease if the sub-adviser's judgment about the quality, relative yield, value or market trends affecting a particular security or issuer, industry, sector, region or market segment, or about the economy or interest rates is incorrect, or if there are imperfections, errors or limitations in the tools and data used by the sub-adviser or manager. 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 sub-adviser and could have an adverse effect on the value or performance of the fund.

Performance: The bar chart and the table below provide some indication of the risks of investing in the fund. The bar chart shows the fund’s performance for the past calendar 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. The bar chart does not reflect the impact of sales charges, which, if reflected, would lower the returns. The table includes deduction of applicable sales charges. Absent any limitation of the fund’s expenses, total returns would be lower. Index returns are since inception of the predecessor fund.

Purchase and Sale of Fund Shares: Class I2 shares of the fund are currently primarily offered for investment by certain funds of funds (also referred to as “strategic asset allocation funds”). Class I2 shares of the fund are also made available to other investors, including institutional investors such as foreign insurers, domestic insurance companies and their separate accounts, and unaffiliated funds, high net worth individuals, and eligible retirement plans

whose recordkeepers or financial service firm intermediaries have entered into agreements with Transamerica Funds or its agents. Investors who received Class I2 shares in connection with the reorganization of a Transamerica Premier Fund into a Transamerica Fund may continue to invest in Class I2 shares of that Transamerica Fund, but may not open new accounts. You buy and redeem shares at the fund’s next-determined net asset value (“NAV”) after receipt of your request in good order.

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.
