Touchstone Value Fund Summary

The Fund’s Investment Goal

The Touchstone Value Fund (the “Fund”) seeks to provide investors with long-term capital growth.

The Fund’s 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. You may qualify for sales charge discounts for Class A shares of Touchstone equity funds and Touchstone fixed income funds if you and your family invest, or agree to invest in the future, at least $25,000 or $50,000, respectively, in Touchstone funds. More information about these and other discounts is available from your financial professional, in the section titled “Choosing a Class of Shares” in the Fund’s prospectus and Statement of Additional Information on pages 61 and 70, respectively, and in Appendix A–Intermediary-Specific Sales Charge Waivers and Discounts to the Fund's prospectus. An investor transacting in Class R6 shares, which do not have any front-end sales charge, contingent deferred sales charge, or other asset-based fee for sales or distribution, may be required to pay a commission to a broker for effecting such transactions on an agency basis. Such commissions are not reflected in the table or in the “Example” below.

	Class A	Class C	Class Y	Institutional Class	Class R6
Shareholder Fees (fees paid directly from your investment)

(1)

Touchstone Advisors, Inc. (the “Adviser” or “Touchstone Advisors”) and Touchstone Strategic Trust (the “Trust”) have entered into a contractual expense limitation agreement whereby Touchstone Advisors will waive a portion of its fees

Touchstone Value FundOctober 28, 2026

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 1.08%, 1.75%, 0.83%, 0.68% and 0.63% of average daily net assets for Classes A, C, Y, Institutional Class, and Class R6 shares respectively. This contractual expense limitation is effective through October 29, 2027, 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 the Adviser 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 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.

(2)

Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement will differ from the ratio of net expenses to average net assets that is included in the Fund's Form N-CSR filing for the fiscal year ended June 30, 2026 due to contractual changes in the Fund's expense limitation agreement effective October 29, 2025.

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					Assuming No Redemption
	Class A	Class C	Class Y	Institutional Class	Class R6	Class C
1 Year	$605	$278	$85	$69	$64	$178
3 Years	$830	$744	$274	$241	$243	$744
5 Years	$1,074	$1,337	$478	$428	$436	$1,337
10 Years	$1,771	$2,944	$1,069	$968	$996	$2,944

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 35% of the average value of the Fund’s portfolio.

The Fund’s Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities of large- and mid-cap companies (generally, companies with market capitalizations of approximately $2.5 billion or higher) that the Fund’s sub-adviser, Barrow, Hanley, Mewhinney & Strauss, LLC d/b/a Barrow Hanley Global Investors (“Barrow Hanley”), believes are undervalued. As part of this strategy, the Fund may invest up to 15% of its assets in foreign equity securities. Equity securities include common and preferred stocks and depositary receipts. Barrow Hanley uses traditional methods of stock selection — research and analysis — to identify securities it believes are undervalued and searches for companies that have one or more of the following characteristics: price to earnings

Touchstone Value FundOctober 28, 2026

ratio below the market, price to book ratio below the market, price to free cash flow ratio below the market, or dividend yields above the market. The Fund's 80% policy is a non-fundamental investment policy that can be changed by the Fund upon 60 days' prior written notice to shareholders.

Although the Fund may also focus its investments within certain sectors, Barrow Hanley uses risk management tools to prevent over-exposure to particular market segments. Barrow Hanley is a “bottom-up” value manager, meaning it analyzes the fundamentals of companies one at a time rather than focusing on broader market themes.

Barrow Hanley generally considers selling a security when it reaches fair value estimate, when earnings forecasts do not appear to justify the current price, when there has been or there is an expectation of an adverse change in the company’s fundamentals, or when other investment opportunities appear more attractive.

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.

●

Large-Cap Risk: Large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes, and also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.

●

Mid-Cap Risk: Stocks of mid-sized companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Mid-sized companies may have limited product lines or financial resources, and may be dependent upon a particular niche of the market.

●

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.

Value Investing Risk: Value investing presents the risk that the Fund’s security holdings may never reach their full intrinsic value because the market fails to recognize what the portfolio managers consider the true business value or because the portfolio managers have misjudged those values.

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

Touchstone Value FundOctober 28, 2026

institutions could suffer losses as interest rates rise or economic conditions deteriorate. In addition, the Fund’s service providers are susceptible to operational and information or cybersecurity risks that could result in losses to a Fund and its shareholders.

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. To the extent that the securities held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the U.S. market is open, there are likely to be deviations between the current price of the securities held by the Fund and their last quoted price or the securities’ quote from the closed foreign market. Foreign markets may be less liquid and more volatile than U.S. markets and offer less protection to investors. To the extent a Fund focuses its investments in a single country or only a few countries in a particular geographic region, economic, political, regulatory or other conditions affecting such country or region may have a greater impact on Fund performance relative to a more geographically diversified fund.

●

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.

Sector and Industry Focus Risk: The Fund may invest a high percentage of its assets in specific sectors and/or industries of the market in order to achieve a potentially greater investment return. As a result, the Fund may be more susceptible to economic, political, and regulatory developments in a particular sector or industry of the market, positive or negative, than a fund that does not invest a high percentage of its assets in specific sectors or industries.

Cybersecurity Risk: Cybersecurity breaches are either intentional or unintentional events that allow an 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 cybersecurity 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 the Fund. Such incidents could affect issuers in which a Fund invests, thereby causing the Fund’s investments to lose value. The Fund has established risk management systems reasonably designed to seek to reduce the risks associated with cyber-events. However, there is no guarantee that the Fund will be able to prevent or mitigate the impact of any or all cyber-events.

The Fund’s Performance

The bar chart and performance table below illustrate some indication of the risks and volatility of an investment in the Fund by showing changes in the Fund’s performance from calendar year to calendar year and by showing how the Fund’s average annual total returns for one year, five years, and ten years compare with the Bloomberg US 3000 Index and the Russell 3000® Index. The Bloomberg US 1000 Value Index and Russell 1000® Value Index show how the Fund’s performance compares against the returns of an index with similar investment universes. The bar chart does not reflect any sales charges, which would reduce your return. The performance table reflects any applicable sales charges. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.
