Touchstone Advisors, Inc. (the “Adviser” or “Touchstone Advisors”) and Touchstone Funds Group Trust (the “Trust”) have entered into a contractual expense limitation agreement whereby Touchstone Advisors will waive a portion of its fees or reimburse certain Fund expenses (excluding dividend and interest expenses relating to short sales; interest; taxes; brokerage commissions and other transaction costs; portfolio transaction and investment related expenses, including expenses associated with the Fund's liquidity providers; other expenditures which are capitalized in accordance with U.S. generally accepted accounting principles; the cost of “Acquired Fund Fees and Expenses”, if any; and other extraordinary expenses not incurred in the ordinary course of business) in order to limit annual Fund operating expenses to 0.69% and 0.59% of average daily net assets for Class Y and Institutional Class shares, respectively. This contractual expense limitation is effective through January 29, 2024, but can be terminated by a vote of the Board of Trustees of the Trust (the “Board”) if it deems the termination to be beneficial to the Fund’s shareholders. The terms of the contractual expense limitation agreement provide that Touchstone Advisors is entitled to recoup, subject to approval by the Board, such amounts waived or reimbursed for a period of up to three years from the date on which Touchstone Advisors reduced its compensation or assumed expenses for the Fund. The Fund will make repayments to the Adviser only if such repayment does not cause the annual Fund operating expenses (after the

Touchstone Anti-Benchmark® International Core Equity FundJanuary 27, 2023

repayment is taken into account) to exceed both (1) the expense cap in place when such amounts were waived or reimbursed and (2) the Fund’s current expense limitation.

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, except as indicated, redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same and that all fee waivers or expense limits for the Fund will expire after one year. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	Assuming Redemption at End of Period
	Class Y	Institutional Class
1 Year	$70	$60
3 Years	$1,012	$389
5 Years	$1,963	$741
10 Years	$4,384	$1,733

Portfolio Turnover. The Fund pays transaction costs, such as brokerage 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 total annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 84% of the average value of its portfolio.

The Fund’s Principal Investment Strategies

The Fund invests, under normal market conditions, at least 80% of its assets in equity securities of non-U.S. issuers. The Fund’s 80% policy is a non-fundamental investment policy that can be changed by the Fund upon 60 days’ prior notice to shareholders. The Fund pursues its objective by seeking to track the total return, before Fund fees and expenses, of the TOBAM Anti–Benchmark® International Core Equity Index (the “Index”). The Index is a proprietary rules–based index created by the Fund’s sub–adviser, TOBAM S.A.S. (“TOBAM”), which is designed to create a more diversified portfolio of equity securities of non-U.S. issuers relative to traditional market capitalization weighted benchmarks. The Fund intends to fully replicate the Index to achieve its investment objective, meaning the Fund will generally invest in all of the component securities of the Index in the same approximate proportions as the Index.

The equity securities that comprise the Index primarily include common and preferred stock of non-U.S. companies that trade on foreign exchanges. TOBAM may replace the common or preferred stock of a foreign issuer with a depositary receipt when it deems the depositary receipt to be more liquid than the corresponding stock. In determining whether a company is foreign, TOBAM primarily looks to both the country of incorporation and the main listing country. If both of these countries are non-U.S., the company is considered non-U.S. for purposes of inclusion in the Index. The Index is comprised of securities of issuers located in developed markets. TOBAM considers the following countries to be developed markets for these purposes: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Luxembourg, Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, and the United Kingdom.

The Index is based on TOBAM’s proprietary quantitative model, which selects and weights companies to maximize diversification. TOBAM quantitatively selects securities, subject to certain constraints, that maximize the portfolio’s patented Diversification Ratio®, a proprietary mathematical metric based on the volatility of each Index constituent and its correlation to the other Index constituents. Such constraints include a minimum and

Touchstone Anti-Benchmark® International Core Equity FundJanuary 27, 2023

maximum weight for any given stock, as well as geographic and country constraints. TOBAM’s Anti-Benchmark® strategy seeks to avoid the concentration risk that exists in traditional market capitalization-weighted indices through its quantitative approach to diversification.

The Index typically is reconstituted (i.e., Index constituents are added or deleted and weights are reset) monthly. The Fund is rebalanced following the same schedule as the Index. The Fund may engage in frequent and active trading as part of its principal investment strategies.

The Fund’s Principal Risks

The Fund’s share price will fluctuate. You could lose money on your investment in the Fund and the Fund could also return less than other investments. Investments in the Fund are not bank guaranteed, are not deposits, and are not insured by the Federal Deposit Insurance Corporation or any other federal government agency. As with any mutual fund, there is no guarantee that the Fund will achieve its investment goal. You can find more information about the Fund’s investments and risks under the “Principal Investment Strategies and Risks” section of the Fund’s prospectus. The Fund is subject to the principal risks summarized below.

Equity Securities Risk: The Fund is subject to the risk that stock prices will fall over short or extended periods of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments, or as a result of irregular and/or unexpected trading activity among retail investors. The prices of securities issued by these companies may decline in response to such developments, which could result in a decline in the value of the Fund’s shares.

•

Preferred Stock Risk: In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds take precedence over the claims of those who own preferred and common stock. If interest rates rise, the fixed dividend on preferred stocks may be less attractive, causing the price of preferred stocks to decline.

Foreign Securities Risk: Investing in foreign securities poses additional risks since political and economic events unique in a country or region will affect those markets and their issuers, while such events may not necessarily affect the U.S. economy or issuers located in the United States. In addition, investments in foreign securities are generally denominated in foreign currency. As a result, changes in the value of those currencies compared to the U.S. dollar may affect (positively or negatively) the value of the Fund’s investments. There are also risks associated with foreign accounting standards, government regulation, market information, and clearance and settlement procedures. Foreign markets may be less liquid and more volatile than U.S. markets and offer less protection to investors.

•

Depositary Receipts Risk: Foreign receipts, which include American Depositary Receipts, Global Depositary Receipts, and European Depositary Receipts, are securities that evidence ownership interests in a security or a pool of securities issued by a foreign issuer. The risks of depositary receipts include many risks associated with investing directly in foreign securities.

Management Risk: In managing the Fund’s portfolio, the Adviser engages one or more sub-advisers to make investment decisions for a portion of or the entire portfolio. There is a risk that the Adviser may be unable to identify and retain sub-advisers who achieve superior investment returns relative to other similar sub-advisers.

Economic and Market Events Risk: Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times, and for varying periods of time, result in unusually high market volatility, which could negatively impact the Fund’s performance and cause the Fund to experience illiquidity, shareholder redemptions, or other potentially adverse effects. Reduced liquidity in credit and fixed-income markets could negatively affect issuers worldwide. Financial institutions could suffer losses as interest rates rise or economic conditions deteriorate. In addition, the Funds' service providers are susceptible to operational and information or cyber security risks that could result in losses to a Fund and its shareholders. Cyber security breaches are either intentional or unintentional events that allow an

Touchstone Anti-Benchmark® International Core Equity FundJanuary 27, 2023

unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause a Fund or Fund service provider to suffer data corruption or lose operational functionality. A cyber security breach could result in the loss or theft of customer data or funds, loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or costs associated with system repairs, any of which could have a substantial impact on a Fund. Such incidents could affect issuers in which a Fund invests, thereby causing the Fund’s investments to lose value.

Passive Investment Risk: As the Fund is intended to track the Index, its portfolio managers do not attempt to take defensive positions under any market conditions, including during declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index.

Quantitative Strategy Risk: TOBAM uses proprietary statistical analyses and models to construct the Index, which the Fund seeks to track. A securities portfolio selected using TOBAM’s proprietary models can perform differently than the market as a whole as a result of the correlation factors used in the analysis to construct the models, the weight placed on each factor, and changes in the factors’ historical trends. As a result, the Fund may be more or less exposed to a risk factor than its individual holdings. Quantitative models are subject to technical issues including programming and data inaccuracies, are based on assumptions, and rely on data that is subject to limitations (e.g., inaccuracies, staleness), any of which could adversely affect their effectiveness or predictive value.

Tracking Error Risk: As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index.

Portfolio Turnover Risk: Frequent and active trading may result in greater expenses to the Fund, which may lower the Fund’s performance and may result in the realization of substantial capital gains, including net short-term capital gains. As a result, high portfolio turnover may reduce the Fund’s returns.

The Return After Taxes on Distributions and Sale of Fund Shares may be greater than other returns for the same period due to a tax benefit of realizing a capital loss on the sale of Fund shares.
