Investment Objective

The CIBC Atlas Mid Cap Equity Fund (the “Fund”) seeks 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.

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

	Institutional Class Shares	Investor Class Shares
Management Fees	0.75%	0.75%
Distribution (12b-1) Fees	None	0.25%
Other Expenses	0.08%	0.23%
Shareholder Servicing Fees	None	0.15%
Other Operating Expenses	0.08%	0.08%
Total Annual Fund Operating Expenses1	0.83%	1.23%

¹ 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 1.00% of the Fund’s average daily net assets until February 28, 2024. 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, 2024.

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:

2

	1 Year	3 Years	5 Years	10 Years
Institutional Class Shares	$85	$265	$460	$1,025
Investor Class Shares	$125	$390	$676	$1,489

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 20% 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 equity securities of mid-capitalization companies. This investment policy may be changed by the Fund upon 60 days’ prior written notice to shareholders. For purposes of this policy, a mid-capitalization company is a company with a market capitalization of between $4 billion and $40 billion at the time of initial purchase. While the Fund expects to invest primarily in common stock, it may also invest in other equity securities, including preferred stock, convertible securities and American Depositary Receipts (“ADRs”). The Fund may invest up to 25% of its net assets in foreign securities, including ADRs.

In selecting securities for the Fund, the Adviser utilizes a bottom-up, fundamental selection process that focuses on identifying companies across various sectors that can deliver consistently strong earnings growth, free cash flow growth and above average return on equity. The Adviser looks for a proven history of growth 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.

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 capitalization exceeds the upper range of capitalizations of companies in the Fund’s benchmark index, 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.

Mid-Capitalization Company Risk – The mid-capitalization companies the Fund invests in may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, investments in these medium-sized companies may pose additional risks, including liquidity risk, because these companies may have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, the mid-capitalization stocks may be more volatile than those of larger companies. These securities may be traded over-the-counter or listed on an exchange.

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.

Investment Style Risk – The Fund pursues a “growth style” of investing, meaning that the Fund invests in equity securities of companies that the Adviser believes will increase their earnings at a certain rate that is generally higher than the rate expected for non-growth companies. If a growth company does not meet these expectations, the price of its stock may decline significantly, even if it has increased earnings. Many growth companies do not pay dividends. Companies that do not pay dividends often have greater stock price declines during market downturns. Over time, a growth investing style may go in and out of favor, and when out

4

of favor, may cause the Fund to underperform other equity funds that use differing investing styles.

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.

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.

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.

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

5

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.

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 and 5 years and since inception compare with those of a broad measure of market performance. 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 the 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.
