Summary Prospectus \| March 1, 2026

CIBC ATLAS INCOME OPPORTUNITIES FUND

(Institutional Class Shares: AWIIX)<br> (Investor Class Shares: AWIVX)

You can find the Fund's prospectus and other information about the Fund online at https://private-wealth.us.cibc.com/cibc-atlas-funds. You can also get this information at no cost by calling 1-855-328-3863, by sending an e-mail request to CIBCAtlasFunds@seic.com, or by asking any financial intermediary that offers shares of the Fund.

**Investment Objective** 

The CIBC Atlas Income Opportunities Fund (the "Fund") seeks current income and long-term capital appreciation.

**Fund Fees and Expenses** 

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. **You may pay other fees, such as brokerage commissions and other fees, including to financial intermediaries, which are not reflected in the table and Example below.**

***Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)***

---

| | | |
|:---|:---|:---|
|  | **Institutional <br> Class Shares** | **Investor <br> Class Shares** |
| &nbsp;&nbsp;Management Fees | 0.60% | 0.60% |
| &nbsp;&nbsp;Distribution (12b-1) Fees |  | 0.25% |
| &nbsp;&nbsp;Other Expenses | 0.08% | 0.23% |
| &nbsp;&nbsp;&nbsp;&nbsp;Shareholder Servicing Fees |  | 0.15% |
| &nbsp;&nbsp;&nbsp;&nbsp;Other Operating Expenses | 0.08% | 0.08% |
| &nbsp;&nbsp;Acquired Fund Fees and Expenses<sup>1</sup> | 0.01% | 0.01% |
| &nbsp;&nbsp;Total Annual Fund Operating Expenses<sup>2,3</sup> | 0.69% | 1.09% |

---

<sup>1</sup> <sup></sup>AFFE are indirect fees and expenses that the Fund incurs from investing in shares of other funds, including money market funds and exchange-traded funds.

<sup>2</sup> CIBC Private Wealth Advisors, Inc. (the "Adviser") has contractually agreed to reduce fees and reimburse expenses to the extent necessary to keep Total Annual Fund Operating Expenses (excluding 12b-1 Fees, Shareholder Servicing Fees, interest, taxes, brokerage commissions, Acquired Fund Fees and Expenses, other expenditures which are capitalized in accordance with generally accepted accounting principles, and extraordinary expenses (collectively, "excluded expenses")) from exceeding 0.85% of the Fund's average daily net assets until February 28, 2027. In addition, the Adviser may receive from the Fund the difference between the Total Annual Fund Operating Expenses (not including excluded expenses) and the expense cap to recoup all or a portion of its prior fee reductions or expense reimbursements made during the rolling three-year period preceding the date of the recoupment if at any point Total Annual Fund Operating Expenses (not including excluded expenses) are below the expense cap (i) at the time of the fee reduction and/or expense reimbursement and (ii) at the time of the recoupment. This Agreement may be terminated: (i) by the Board of Trustees (the "Board") of The Advisors' Inner Circle Fund (the "Trust"), for any reason at any time, or (ii) by the Adviser, upon ninety (90) days' prior written notice to the Trust, effective as of the close of business on February 28, 2027. 

<sup>3</sup> The Total Annual Fund Operating Expenses in this fee table do not correlate to the expense ratios in the Fund's Financial Highlights because the Financial Highlights include only the direct operating expenses incurred by the Fund, and exclude Acquired Fund Fees and Expenses. 

***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** |
| &nbsp;&nbsp;Institutional Class Shares | $70 | $221 | $384 | $859 |
| &nbsp;&nbsp;Investor Class Shares | $111 | $347 | $601 | $1329 |

---

***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 total annual Fund operating expenses or in the example, affect the Fund's performance. During its most recent fiscal year, the Fund's portfolio turnover rate was 24% of the average value of its portfolio.

**Principal Investment Strategies** 

Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in income producing securities. This investment policy may be changed by the Fund upon 60 days' prior written notice to shareholders. The Fund invests in a combination of common stock, preferred stock, convertible securities, fixed income securities (including corporate bonds, mortgage-backed and asset-backed securities, U.S. government securities, and money market instruments), and other investment companies (including exchange-traded funds ("ETFs") and closed-end investment companies ("closed-end funds")). The Fund may invest up to 25% of its net assets in foreign securities, including American Depositary Receipts ("ADRs"). The Fund focuses on companies with market capitalizations within the range of the Russell 1000<sup>®</sup> Index during the prior year, but may invest in companies not included in the Index. As of December 31, 2025, the market capitalization range for the Russell 1000<sup>®</sup> Index was approximately $1.3 billion to $4.5 trillion. The Fund may invest without limit in securities of any credit quality, including securities that are rated below investment grade ("high yield" or "junk"

bonds) and those in default. The Fund may also invest up to 25% of its assets in the sale (writing) of covered call or put options on common stocks to generate additional income and reduce volatility.

In selecting securities for the Fund, the Adviser utilizes a bottom-up, fundamental selection process that focuses on identifying companies across various sectors that are attractively valued and can deliver consistently strong free cash flow growth and above average return on equity. The Adviser looks for a proven history of solid business execution in the companies in which the Fund invests, because the Adviser believes that it is indicative of the value of the company's underlying franchise or market position, and companies with such a history typically have a proprietary product or business approach that allows them to be leaders within their respective industries. Based on an assessment of relative and absolute attractiveness, an investment may be made in a company's common stock, preferred stock, and/or debt.

The Fund intends to buy and hold securities of companies for the long-term, and seeks to limit portfolio turnover. The Fund may sell a security, however, when a company's fundamental business prospects or ability to generate cash deteriorates, its management becomes less stable or it becomes overvalued, or when more attractive alternatives exist.

**Principal Risks** 

As with all mutual funds, there is no guarantee that the Fund will achieve its investment objective. You could lose money by investing in the Fund. **A Fund share is not a bank deposit and it is not insured or guaranteed by the FDIC or any government agency.** The principal risk factors affecting shareholders' investments in the Fund are set forth below.

**Equity Risk** – Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund's equity securities may fluctuate drastically from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund's performance and cause

losses on your investment in the Fund. These factors contribute to price volatility, which is the principal risk of investing in the Fund.

**High Yield Bond Risk** – High yield, or "junk," bonds are highly speculative securities that are usually issued by smaller, less creditworthy and/or highly leveraged (indebted) companies. Compared with investment-grade bonds, high yield bonds are considered to carry a greater degree of risk and are considered to be less likely to make payments of interest and principal. In particular, lower-quality high yield bonds (rated CCC, CC, C, or unrated securities judged to be of comparable quality) are subject to a greater degree of credit risk than higher-quality high yield bonds and may be near default. High yield bonds rated D are in default. Market developments and the financial and business conditions of the corporation issuing these securities generally influence their price and liquidity more than changes in interest rates, when compared to investment-grade debt securities.

**Convertible Securities Risk** – The value of a convertible security is influenced by changes in interest rates (with investment value declining as interest rates increase and increasing as interest rates decline) and the credit standing of the issuer. The price of a convertible security will also normally vary in some proportion to changes in the price of the underlying common stock because of the conversion or exercise feature.

**Risks of Investing in Other Investment Companies** – To the extent the Fund invests in other investment companies, such as ETFs and closed-end funds, the Fund will be subject to substantially the same risks as those associated with the direct ownership of the securities held by such other investment companies. As a shareholder of another investment company, the Fund relies on that investment company to achieve its investment objective. If the investment company fails to achieve its objective, the value of the Fund's investment could decline, which could adversely affect the Fund's performance. By investing in another investment company, Fund shareholders indirectly bear the Fund's proportionate share of the fees and expenses of the other investment company, in addition to the fees and expenses that Fund shareholders directly bear in connection with the Fund's own operations.

Because closed-end funds and ETFs are listed on national stock exchanges and are traded like stocks listed on an exchange, their shares potentially may trade at a discount or premium to their net asset value. Investments in closed-end funds and ETFs are also subject to brokerage and other trading costs, which could result in greater expenses to the Fund. In addition, because the value of closed-end funds and ETF shares depends on the demand in the market, the Adviser may not be able to liquidate the Fund's holdings at the most optimal time, which could adversely affect Fund performance.

**Derivatives Risk** – The Fund's use of put and call options is subject to market risk, leverage risk, correlation risk, liquidity risk, credit risk and valuation risk. Credit risk is described above. Leverage risk and liquidity risk are described below. Market risk is the risk that the market value of an investment may move up and down, sometimes rapidly and unpredictably. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Valuation risk is the risk that the derivative may be difficult to value. Each of these risks could cause the Fund to lose more than the principal amount invested in a derivative instrument.

**Preferred Stock Risk** – Preferred stocks are sensitive to interest rate changes, and are also subject to equity risk, which is the risk that stock prices will fall over short or extended periods of time. The rights of preferred stocks on the distribution of a company's assets in the event of a liquidation are generally subordinate to the rights associated with a company's debt securities.

**Leverage Risk** – The use of leverage can amplify the effects of market volatility on the Fund's share price and may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations.

**Credit Risk** – The risk that the issuer of a security or the counterparty to a contract will default or otherwise become unable to honor a financial obligation.

**Corporate Fixed Income Securities Risk** – The prices of the Fund's corporate fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness and business prospects of individual issuers.

**Fixed Income Market Risk** – The prices of the Fund's fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments and their agencies. In the case of foreign securities, price fluctuations will reflect international economic and political events, as well as changes in currency valuations relative to the U.S. dollar.

**Interest Rate Risk** – The risk that the value of fixed income securities will fall due to rising interest rates.

**Liquidity Risk** – The risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on Fund management or performance.

**Asset-Backed Securities Risk** – Payment of principal and interest on asset-backed securities is dependent largely on the cash flows generated by the assets backing the securities, and asset-backed securities may not have the benefit of any security interest in the related assets.

**Mortgage-Backed Securities Risk** – Mortgage-backed securities are affected by, among other things, interest rate changes and the possibility of prepayment of the underlying mortgage loans. Mortgage-backed securities are also subject to the risk that underlying borrowers will be unable to meet their obligations.

**U.S. Government Securities Risk** – The Fund's investment in U.S. government obligations may include securities issued or guaranteed as to principal and interest by the U.S. government, or its agencies or instrumentalities. Payment of principal and interest on U.S. government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. There can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so. In addition, U.S. government securities are not guaranteed against price movements due to changing interest rates.

**Foreign Company Risk** – Investing in foreign companies, including direct investments and through ADRs, which are traded on U.S. exchanges and represent an ownership in a foreign security, poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign companies generally are denominated in a foreign currency. Changes in the value of a currency compared to the U.S. dollar may affect (positively or negatively) the value of the Fund's investments. These currency movements may occur separately from, and in response to, events that do not otherwise affect the value of the security in the issuer's home country. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the "SEC") and foreign companies are generally not subject to the regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publicly available information about foreign securities than is available about domestic securities. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which would reduce income received from the securities comprising the portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. While ADRs provide an alternative to directly

purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs continue to be subject to many of the risks associated with investing directly in foreign securities.

**Foreign Currency Risk** – As a result of the Fund's investments in securities or other investments denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case, the dollar value of an investment in the Fund would be adversely affected.

**Performance Information** 

The bar chart and the performance table below illustrate the risks and volatility of an investment in the Fund by showing changes in the Fund's Institutional Class Shares' performance from year to year and by showing how the Fund's Institutional Class Shares' average annual total returns for 1, 5 and 10 years and since inception compare with those of a broad measure of market performance and more narrowly based indices with characteristics relevant to the Fund's investment strategies. Of course, the Fund's past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

As of the date of this Prospectus, Investor Class Shares of the Fund have not commenced operations and therefore have no performance information to report. Investor Class Shares of the Fund would have substantially similar performance as Institutional Class Shares because the shares are invested in the same portfolio of securities and the returns would generally differ only to the extent that expenses of Investor Class Shares are higher than the expenses of Institutional Class Shares, in which case the returns for Investor Class Shares would be lower than those of Institutional Class Shares.
