Fund Investment Objective

The Cambiar Opportunity Fund (the “Fund”) seeks total return and capital preservation.

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 be required to pay commissions and/or other forms of compensation to a broker for transactions in Institutional Class Shares and Investor Class Shares, which are not reflected in the table or the example below.

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	0.60%	0.60%
Other Expenses	0.19%	0.40%
Shareholder Service Fees1	None	0.21%
Other Operating Expenses	0.19%	0.19%
Total Annual Fund Operating Expenses	0.79%	1.00%
Less Fee Reductions and/or Expense Reimbursements2	(0.14)%	(0.14)%
Total Annual Fund Operating Expenses After Fee Reductions and/or Expense Reimbursements	0.65%	0.86%

¹ The Fund’s Investor Class Shares are subject to a maximum annual shareholder servicing fee of 0.25% of the average daily net assets of the Fund’s Investor Class Shares.

² Cambiar Investors, LLC (“Cambiar,” or, the “Adviser”) has contractually agreed to reduce fees and reimburse expenses in order to keep net operating expenses (excluding any class-specific expenses (including shareholder servicing fees), interest, taxes, brokerage commissions and other costs and expenses relating to the securities that are purchased and sold by the Fund, acquired fund fees and expenses, other expenditures which are capitalized in accordance with generally accepted accounting principles, and other non-routine expenses (collectively, “excluded expenses”)) from exceeding 0.65% of the average daily net assets of each of the Fund’s share classes until March 1, 2025. 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 the fees waived or reduced or other payments remitted by the Adviser during the rolling three-year period preceding the date of the reimbursement 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 waiver or expense payment; and (ii) at the time of the reimbursement. 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 March 1, 2025. This Agreement automatically terminates upon the termination of the investment advisory agreement.

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 (including one year of capped expenses in each period) 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
Institutional Class Shares	$66	$238	$425	$965
Investor Class Shares	$88	$304	$539	$1,212

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 its most recent fiscal year, the Fund’s portfolio turnover rate was 51% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests primarily in a diversified portfolio of common stocks of companies with a market capitalization in excess of $10 billion at time of purchase.

In selecting investments for the Fund, the Adviser uses a fundamental, relative value investment approach to build a diversified portfolio of companies. Companies entering the portfolio generally need to satisfy Cambiar’s criteria on four levels: quality, valuation, value creation/catalyst, and risk-reward criteria:

Quality – Cambiar’s analysts seek companies that are best-of-breed operators within their industries. Eligible businesses for the portfolio are evaluated based on the following characteristics:

● Management – Management teams should have a track record of success that has benefitted not just public shareholders such as the Fund, but a wide range of stakeholders, e.g., employees, customers, suppliers.

● Consistent margins – Companies with above average and consistent margins suggest a relatively high value-add product or service and defensible market position.

● Return on invested capital (“ROIC”) – Demonstrates a pattern of value creation and capital discipline.

● Low leverage – Companies with strong balance sheets do not need to depend on the vagaries of the debt and/or equity markets to sustain their businesses.

● Free cash flow (“FCF”) – We view FCF to be a better measure of economic value creation versus alternative metrics such as earnings before interest, taxes, depreciation, and amortization (“EBITDA”) or earnings per share (“EPS”) because Cambiar believes that FCF is less subject to manipulation.

Valuation – Cambiar evaluates broadly accepted and recognized financial measures in gauging valuation. An underlying premise of the Cambiar philosophy is that certain industries tend to follow certain valuation ranges; the market does not randomly value stocks. Our preference is to invest in companies that are trading at a reasonable valuation relative to their historical trading range. The Cambiar team will use a variety of metrics in gauging valuation; examples include Price/Earnings, Price/Book Value and FCF Yield.

Value Creation/Catalyst – Cambiar’s research process also seeks to identify some form of fundamental positive development(s) that we believe the market is overlooking/underappreciating. Such catalysts may come in varying forms – examples include new product introductions, managerial changes, divestiture of an underperforming division, or simply better financial performance. Valuation, in and of itself, is not a catalyst – there must be some identifiable event that we believe will cause investors to positively reassess the business.

Risk-Reward Criteria – The final criteria is the investment team’s assessment of the issuer’s upside potential: companies entering the portfolio should possess an attractive total return potential that includes both price appreciation and dividends (if applicable) over a forward 1- to 2-year timeframe. While Cambiar may not achieve this return target over the desired timeframe – or at all – the return requirement is intended to channel research efforts toward those situations that appear to offer the most compelling risk/return tradeoffs.

The Adviser constructs the Fund’s portfolio on a security-by-security basis, with the goal of building a portfolio that strikes a balance between the Adviser’s conviction in an investment and portfolio diversification. The Adviser seeks to manage the Fund’s risk through its research process as well as limits on individual position sizes and allocations to an economic sector.

The Adviser will consider liquidating or reducing its investment in a company if: (a) the investment thesis is realized and the stock reaches its price target, (b) the stock price increases disproportionately relative to actual company developments, (c) position size, country or sector limits are reached, or (d) there is a negative change in fundamentals, or the investment thesis fails to develop as expected. The Adviser will not sell a stock simply because of a decline in price, and may add to the position if the investment thesis remains intact.

Principal Risks of Investing in the Fund

As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. A Fund share is not a bank deposit and is not insured or guaranteed by the FDIC or any other government agency. You should consider your investment goals, time horizon, and risk tolerance before investing in the Fund. The principal risk factors affecting shareholders’ investments in the Fund are set forth below.

Since it purchases equity securities, the Fund is subject to the risk that stock prices may 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 significantly 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, and hence, the Fund, may suffer a decline in response. Portfolio securities may be traded over-the-counter or listed on an exchange.

The large capitalization companies in which the Fund may invest may lag the performance of smaller capitalization companies because large capitalization companies may experience slower rates of growth than smaller capitalization companies and may not respond as quickly to market changes and opportunities.

A number of factors can affect financial markets generally, which in turn, can impact the value of the Fund’s investments. Economic considerations such as GDP growth, interest rates, inflation, monetary and fiscal policy, barriers to capital formation and reinvestment, market instability, and budgetary deficits are key considerations in how overall markets perform. Political factors, including elections and political instability and unrest, foreign or domestic, can affect the extent to which investors choose to participate in financial markets. 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 unforeseeable 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.

The Fund is an actively managed mutual fund that pursues a “value” style of investing. Value investing focuses on companies whose stock appears undervalued in light of factors such as the company’s earnings, book value, revenues or cash flow. If the Adviser’s assessment of market conditions, or a company’s value or prospects for meeting or exceeding earnings expectations is inaccurate, the Fund may not achieve its intended results and could suffer losses or produce poor performance relative to other funds or market benchmarks. In addition, “value stocks” can continue to be undervalued by the market for long periods of time, and may never achieve the Adviser’s expected valuation.

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 Investor Class Shares’ performance from year to year for the past 10 years and by showing how the Fund’s average annual total returns for 1, 5 and 10 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.

Updated performance information is available at www.cambiar.com or by calling 1-866-777-8227.

During the periods shown in the chart, the Fund’s Investor Class Shares’ highest return for a quarter was 19.25% (quarter ended 6/30/2020) and the lowest return for a quarter was (21.60)% (quarter ended 3/31/2020).

Average Annual Total Returns for Periods Ended December 31, 2023

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold

their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). After-tax returns are shown for only the Investor Class Shares. After-tax returns for Institutional Class Shares will vary.

Institutional Class Shares of the Fund commenced operations on November 3, 2005. As a result, the performance information provided for Institutional Class Shares incorporates the returns of Investor Class Shares of the Fund for periods before November 3, 2005. Institutional Class Shares would have substantially similar performance as Investor Class Shares because the shares are invested in the same portfolio of securities and the annual returns would generally differ only to the extent that total expenses of Institutional Class Shares are lower.

	1 Year	5 Years	10 Years	Since Inception (6/30/98)
Investor Class Shares
Fund Returns Before Taxes	16.84%	15.01%	9.60%	8.97%
Fund Returns After Taxes on Distributions	14.37%	13.04%	7.50%	7.62%
Fund Returns After Taxes on Distributions and Sale of Fund Shares	11.51%	11.71%	7.24%	7.25%

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 and its related companies may pay the intermediary for the sale of Fund shares and related services.
