Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Strategic Enhanced Yield Fund. You may qualify for sales charge discounts if you and your family invest or agree to invest in the future, at least $200,000 in Cavanal Hill Funds. More information about these and other discounts is available from your financial professional and in the section "Initial Sales Charge (Bond and Equity Funds, Class A Shares Only)" on page 46 of the prospectus and "Contingent Deferred Sales Charges (CDSC-Class A and C Only)" on page 47 in the prospectus and in the section "Additional Purchase and Redemption Information" on page 34 of the Statement of Additional Information. An investor transacting in Institutional 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 or other financial intermediary for effecting such transactions on an agency basis. Such commissions are not reflected in the tables or the example below. Shares of the Fund are available in other share classes that have different fees and expenses.

* Class A Shares are available with no front-end sales charge on investments of $200,000 or more. There is, however, a contingent deferred sales charge (CDSC) of 1.00% on any Class A Shares upon which a dealer concession was paid that are sold within one year of purchase.

† The Adviser has contractually agreed to waive fees payable to it or reimburse certain expenses so that expenses (other than extraordinary expenses and any Acquired Fund Fees and Expenses) for each Class do not exceed 0.76%, plus class-specific fees, until December 31, 2026. Affiliates of the Adviser have contractually agreed to waive all Shareholder Servicing Fees to which they are entitled. The affiliate waivers result in a reduction of the Shareholder Servicing Fee paid by all purchasers of a Class to the extent shown in the table. Contractual waivers are in place for the period through December 31, 2026, and may only be terminated or modified with the approval of the Fund's Board of Trustees.

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 of your 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:

Portfolio Turnover

The Strategic Enhanced Yield 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 Fund's portfolio turnover rate was 112% of the average value of its portfolio.

Principal Investment Strategy

The Fund seeks to achieve its investment objective by investing in a diversified portfolio of fixed income instruments of varying maturities. In an effort to actively enhance total return and minimize risk, the Fund will engage in opportunistic trading among various sectors based on the perceived market anomalies and inefficiencies detected by the Fund's portfolio managers, which may be found in illiquid or thinly traded securities and those that may not accurately reflect relevant market information. Total return is defined as a percentage change, over a specified time period, in a mutual fund's net asset value, with the ending net asset value adjusted to account for the reinvestment of all distributions of dividends and capital gains.

Under normal circumstances, the Fund invests at least 80% of its net assets in fixed income instruments, both domestic and foreign. This investment policy will not be changed by the Fund without at least 60 days' prior notice to shareholders. The principal "Fixed income instruments" that the Fund invests in are securities issued or guaranteed by the U.S. Government and its agencies and instrumentalities, U.S. corporate bonds, global corporate bonds and sovereign bonds denominated in U.S. and non-U.S. dollars, mortgage-backed securities, asset-backed securities, municipal securities, and privately-issued securities that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act of 1933 (the "1933 Act"). Privately issued securities are those securities that are exempt from registration under the 1933 Act and that may be resold only in accordance with Rule 144A, which allows for the private resale of securities to qualified institutional buyers, and Regulation S, which allows for the private sale of securities outside the U.S. The mortgage-backed securities in which the Fund invests are fixed rate mortgage-backed securities backed by Fannie Mae, Freddie Mac, and Ginnie Mae.

The Fund may also invest in securities listed, traded or dealt in foreign countries, including emerging markets countries. Such securities may be denominated in foreign currencies and include sovereign, supra-national and quasi-sovereign bonds and debt instruments. There is no limit on the foreign issuers in which the Fund can invest, provided that the Fund will not invest in any foreign issuer or country in which investment is prohibited by law. The Fund will consider an issuer to be doing a substantial amount of business outside the U.S. if it derives more than 50% of its assets, revenue or income outside of the U.S. The Fund may also invest in preferred stock. The Fund may invest in U.S. Treasury futures for hedging purposes. U.S. Treasury futures with economic characteristics similar to fixed income instruments will be included as investments that satisfy the Fund's 80% policy discussed above.

"Investment-grade" securities are securities that are rated by at least one major rating agency in one of its top four rating categories, meaning those securities that have a rating of Baa3 by Moody's, BBB- by S&P or BBB- by Fitch Ratings Ltd., or, if unrated, that are determined by the Adviser to be of similar quality, at the time of purchase. The Fund will seek to enhance yield by investing up to a combined 60% of its assets in fixed income securities rated below investment grade (also known as "high yield securities" or "junk bonds"), emerging market debt securities, including both sovereign and corporate issuers, and securities denominated in foreign currencies.

The Adviser expects that the Fund's average duration will range between 20% shorter and 20% longer than that of the Bloomberg US Aggregate Index. For example, on October 31, 2025, the duration was 5.9 years, meaning the Fund's average duration would range between 4.75 years (20% shorter than the Bloomberg US Aggregate Index) and 7.12 years (20% longer than the Bloomberg US Aggregate Index). Duration provides a measure of a fund's sensitivity to changes in interest-rates. In general, the longer a fund's duration, the more its price will fluctuate when interest rates change. A fund with a duration of

10 years is twice as sensitive to interest rate changes as a fund with a five-year duration. A fund with a five-year duration would generally be expected to lose 5% from its net asset value if interest rates rose by one percentage point or gain 5% if interest rates fell by one percentage point.

In selecting fixed income instruments for the Fund, the Adviser actively monitors potential investment opportunities throughout the world and bases its purchase and sale decisions on a fundamental analysis of global economic trends and underlying global economic fundamentals.

Principal Investment Risks

Loss of money is a risk of investing in the Fund. In addition, the principal risks of investing in the Fund, which could adversely affect the Fund's net asset value, yield or total return are:

• Credit Risk - Credit risk is the possibility that the issuer of a debt instrument or a counterparty to an agreement fails to fulfil its obligations, reducing the Fund's return. This includes failure by a bond issuer to repay interest and principal.

• Market Risk - The value of the Fund's assets will fluctuate as the markets in which the Fund invests fluctuate. The value of the Fund's investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events, such as inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund's investments may be negatively affected by the occurrence of global events such as war, military conflict, acts of terrorism, social unrest, environmental disasters, natural disasters or events, recessions, supply chain disruptions, political instability, and infectious disease epidemics or pandemics.

• Liquidity Risk - Certain securities may be difficult or impossible to sell at the time and the price that would normally prevail in the market. The portfolio manager may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments. If a Fund is required to sell securities quickly or at a particular time (including sales to meet redemption requests) the Fund could realize a loss.

• Interest Rate Risk - The value of the Fund's interest-bearing investments may decline due to an increase in interest rates. In general, the longer a security's maturity, the greater the interest rate risk. For a portfolio with a duration of 3 years, each 1% rise in interest rates would reduce the value of the portfolio by an estimated 3%. The Fund's yield may decrease due to a decline in interest rates. Very low or negative interest rates may magnify interest rate risk. Recent and any future declines in interest rate levels could cause the Fund's earnings to fall below the Fund's expense ratio, resulting in a negative yield and a decline in the Fund's share price. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, may result in heightened market volatility and may detract from Fund performance to the extent the Fund is exposed to such interest rates.

• Foreign Investment Risk - The risk associated with higher transaction costs, delayed settlements, currency controls or adverse economic and political developments. This also includes the risk that fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect an investment. Exchange rate volatility may affect the ability of an issuer to repay U.S. dollar denominated debt, thereby increasing credit risk. Foreign securities may also be affected by incomplete or inaccurate financial information on companies. There is a risk of loss attributable to social upheavals, unfavorable governmental or political actions, seizure of foreign deposits, changes in tax or trade statutes, and governmental collapse and war. These risks are more significant in emerging markets.

• Valuation Risk - The risk associated with the assessment of appropriate pricing in a changing market where trading information may not be readily available.

• Non-U.S. Denominated Currency Risk - Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity's debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.

• Emerging Market Risk - Risks associated with investing in emerging market securities include potentially restrictive political and economic structures and abrupt changes to those structures, changes in price visibility and liquidity in markets and securities, fluctuations in currency exchange rates, volatility in interest rates, and sudden changes in tax policy.

• Prepayment/Call Risk - There is a chance that the repayment of an asset-backed or mortgage-backed obligation will occur sooner than expected. Call risk is the possibility that, during periods of falling interest rates, a bond issuer will "call" - or repay - its bond before the bond's maturity date.

• High Yield Securities Risk - Fixed income securities rated below investment grade and unrated securities of similar credit quality (commonly referred to as "junk bonds" or high yield securities) are regarded as being predominantly speculative as to the issuer's ability to make payments of principal and interest. Investments in such securities involves substantial risk. Issuers of high yield securities may be highly leveraged and may not have available to them more traditional methods of financing. Therefore, the risks associated with acquiring the securities of such issuers generally are greater than is the case with investment grade securities. The value of high yield securities tends to be very volatile due to such factors as specific corporate developments, interest rate sensitivity, less secondary market activity, and negative perceptions of high yield securities and the junk bond markets generally, particularly in times of market stress.

• Mortgage-Backed Securities Risk - The value of the Fund's mortgage-backed securities can fall if the owners of the underlying mortgages pay off their mortgages sooner than expected, which could happen when interest rates fall, or later than expected, which could happen when interest rates rise. If the underlying mortgages are paid off sooner than expected, the Fund may have to reinvest this money in mortgage-backed or other securities that have lower yields.

• Asset-Backed Securities Risk - Payment of interest and repayment of principal may be impacted by the cash flows generated by the assets backing asset-backed securities. The value of the Fund's asset-backed securities may also be affected by changes in interest rates, the availability of information concerning the interests in and structure of the pools of purchase contracts, financing leases or sales agreements that are represented by these securities, the creditworthiness of the servicing agent for the pool, the originator of the loans or receivables, or the entities that provide any supporting letters of credit, surety bonds, or other credit enhancements.

• Derivative Risk - The risk of investing in derivative instruments, including liquidity, interest rate, market, credit and management risks, mispricing or improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested.

• Leverage Risk - The risk associated with securities or practices that multiply small index or market movements into large changes in value. Leverage is often associated with investments in derivatives, but also may be embedded directly in the characteristics of other securities. Leverage risk is hedged when a derivative (a security whose value is based on another security or index) is used as a hedge against an opposite position that a Fund also holds, any loss generated by the derivative should be substantially offset by gains on the hedged investment, and vice versa. Hedges are sometimes subject to imperfect matching between the derivative and underlying security, and there can be no assurance that a Fund's hedging transactions will be effective.

• Private/Restricted Securities Risk - The Fund can invest in private placements and restricted securities. Such investments involve a high degree of business and financial risk and can result in substantial or complete losses. Competition among private funds can be intense and there is no assurance that the marketing efforts of any particular portfolio company will be successful or that its business will succeed. Additionally, privately held companies are not subject to Securities and Exchange Commission reporting requirements, are not required to maintain their accounting records in accordance with generally accepted accounting principles, and are not required to maintain effective internal controls over financial reporting. As a result, timely or accurate information may at times not be readily available about the business, financial condition and results of operations of the privately held companies in which the Fund invests.

• Redemption Risk - The risk that heavy redemptions could cause the Fund to liquidate its assets at inopportune times or at a loss or depressed value, particularly during periods of declining or illiquid markets, and that could affect the fund's ability to maintain a $1.00 share price. Redemption risk is greater to the extent that the fund has investors with large shareholdings, short investment horizons or unpredictable cash flow needs. The redemption by one or more large shareholders of their holdings in the fund could cause the remaining shareholders in the fund to lose money.

• Floating Rate Notes Risk - Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed notes of the same maturity.

• Hedging Risk - Hedging may not be effective based on timing, the underlying instrument hedged, or duration of the hedge.

• Management Risk - There is no guarantee that the investment techniques and risk analyses used by the Fund's portfolio managers will produce the desired results.

• Regulatory Risk - The risk that a change in laws or regulations will materially affect a security, business, sector or market. A change in laws or regulations made by the government or a regulatory body can increase the costs of operating a business, reduce the attractiveness of investment and/or change the competitive landscape. Regulatory risk also includes the risk associated with federal and state laws which may restrict the remedies that a lender has when a borrower defaults on loans. These laws include restrictions on foreclosures, redemption rights after foreclosure, federal and state bankruptcy and debtor relief laws, restrictions on "due on sale" clauses, and state usury laws.

To the extent that the Fund makes investments with additional risks, those risks could increase volatility or reduce performance. The Fund may trade securities actively, which could increase its transaction costs (thus lowering performance) and may increase the amount of taxes that you pay. For more information about these risks, please refer to the section titled "Investment Practices and Risks" in the Fund's prospectus. An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
