#### Investment Objective
To seek current income with liquidity and stability of principal.

#### 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 U.S. Treasury Fund. **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.

**Shareholder Fees** (fees paid directly from your investment): None.

† Affiliates of the Adviser have contractually agreed to waive all Shareholder Servicing Fees to which they are entitled paid by Select Shares and 0.17% paid by Institutional Shares. 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:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **1 Year** | **3 Years** | **5 Years** | **10 Years** |
|  Administrative Shares | $68 | $215 | $375 | $839 |
|  Institutional Shares | $27 | $119 | $220 | $516 |
|  Select Shares | $17 | $111 | $212 | $510 |

#### Principal Investment Strategy
To pursue its objective, under normal circumstances, the Fund invests at least 99.5% of its total assets in cash, U.S. Government Securities, or repurchase agreements collateralized by U.S. Government Securities and other U.S. Treasury investment companies. The Fund also invests at least 80% of its net assets in U.S. Treasury Obligations or repurchase agreements collateralized by U.S. Treasury Obligations. These policies will not be changed without at least 60 days prior notice to shareholders. As a money market fund, the dollar-weighted average portfolio maturity of the Fund will not exceed 60 days and the dollar-weighted average portfolio life cannot exceed 120 days.

#### Principal Investment Risks
You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund's sponsor has no legal obligation to provide financial support to the Funds, beyond what is disclosed in the footnote under the "Annual Fund Operating Expenses" table, and you should not expect that the sponsor will provide additional financial support to the Fund at any time. 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:

• **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.

• **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.

• **Investment in Other Investment Companies Risk** — Investments in other investment companies are subject to market and selection risk. In addition, if the Fund acquires shares of investments companies, shareholders bear both their proportionate share of expenses in the Fund (including management fees and other expenses) and, indirectly, the expenses of the investment companies.

• **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.

• **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.

#### Performance Information
The bar chart and the performance table below illustrate some of the risks and return volatility of an investment in the Fund by showing changes in the Fund's performance from year to year and by showing the Fund's average annual returns for 1, 5 and 10 years. The Fund's past performance does not necessarily indicate how the Fund will perform in the future. Updated performance information may be obtained on the Fund's website www.cavanalhillfunds.com or by calling 1-800-762-7085.

This bar chart shows changes in the Fund's performance from year to year<sup>1</sup>. The returns for Institutional and Select Shares will differ from the returns for Administrative Shares (which are shown in the bar chart) because of differences in the expenses of each Class.

#### Annual Total Returns for Administrative Shares and predecessor (Periods Ended 12/31)

<sup>1</sup>The performance information shown above is based on a calendar year. The Fund's total return from 1/1/25 to 9/30/25 was 2.78%.

This table shows the Fund's average annual total returns for periods ended December 31, 2024. The Select Shares commenced operations on December 26, 2017. The performance shown for periods prior to commencement of operations of the Select Shares is that of the Institutional Shares. The shares would have substantially similar performance because shares are invested in the same portfolio of securities. The performance shown is lower than actual returns would have been because the predecessor class had a higher expense ratio.

#### Average Annual Total Returns for Administrative, Institutional and Select Shares and predecessors. <br>(Periods Ended 12/31/2024)

#### Payments to Broker-Dealers and Other Financial Intermediaries
If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund or its service providers may pay the intermediary for the sale of Fund shares and related services.

Ask your salesperson or visit your financial intermediary's website for more information. In addition, if you purchase shares that do not have any front-end sales charge, contingent deferred sales charge, or other asset-based fee for sales or distribution from a broker or other financial intermediary on an acting agency basis, you may be required to pay a commission in an amount charged and separately disclosed to you by such party.
