You may be required to pay commissions and/or other forms of compensation to a broker for transactions in Institutional 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)

	Investor Shares	Institutional Shares
Management Fees	0.60%	0.60%
Distribution and/or Service (12b-1) Fees	0.25%	None
Other Expenses	0.47%	0.32%
Shareholder Servicing Fees	0.15%	None
Other Operating Expenses	0.32%	0.32%

ARGA Investment Management, LP (the "Adviser") has contractually agreed to waive fees and reimburse expenses to the extent necessary to keep Total Annual Fund Operating Expenses excluding any class-specific expenses (including Distribution and/or Service (12b-1) Fees and Shareholder Servicing Fees), brokerage commissions, acquired fund fees and expenses, dividend and interest securities sold short, and certain other expenses ("Gross Expenses") from exceeding 0.75% of the average daily net assets of each of the Fund's share classes until April 30, 2026 (the "contractual expense limit"). In addition, the Adviser may receive from the Fund all or a portion of its prior fee waivers or expense reimbursements made during the rolling three-year period preceding the date of the recoupment if at any point Gross Expenses are below the contractual expense limit (i) at the time of the fee waiver 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 III (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 April 30, 2026.

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
Investor Shares	$117	$402	$707	$1,575
Institutional Shares	$77	$276	$493	$1,116

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 the most recent fiscal year, the Fund's portfolio turnover rate was 38% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests primarily in equity securities of companies located in any part of the world and in other instruments, such as shares of exchange-traded funds ("ETFs"), that have economic characteristics similar to such securities.

The Fund mainly invests in common stocks, but may also invest in depositary receipts (including American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs") and Global Depositary Receipts ("GDRs")), preferred stocks, participation notes ("P-Notes"), private placements, ETFs and real estate investment trusts ("REITs"). Depositary receipts are certificates typically issued by a bank or trust company that represent ownership interests in securities of non-U.S. companies. Typically, the Fund invests in securities of companies with a market capitalization of at least

2

$1 billion. The Fund may invest in securities denominated in any currency.

Under normal market conditions, the Fund will invest in at least three countries, including the United States, and at least 40% of its assets will be invested in non-U.S. companies, in both developed and emerging market countries. The Fund considers a company to be a non-U.S. company if any of the following apply: (1) the company's principal securities trading market is in a non-U.S. country; (2) while traded in any market, alone or on a consolidated basis, the company derives 50% or more of its business, revenues or profits from non-U.S. countries; (3) the company has 50% or more of its assets, employees or operations located in non-U.S. countries; or (4) the company is organized under the laws of, or has a principal office in, a non-U.S. country. The Adviser has discretion to determine which countries are "emerging market countries," although those classified by Morgan Stanley Capital International ("MSCI") as emerging market countries typically will be included, together with other countries deemed by the Adviser to be at a similar stage of economic development as such countries. From time to time, the Fund may focus its investments in a particular country, geographic region or sector. The Fund may invest in A-Shares of companies based in the People's Republic of China ("China") that trade on the Shanghai Stock Exchange and the Shenzhen Stock Exchange through the Shanghai - Hong Kong and Shenzhen - Hong Kong Stock Connect programs ("Stock Connect"). Stock Connect is a mutual stock market access program designed to, among other things, enable foreign investments in China.

In seeking to achieve the Fund's investment objective, the Adviser utilizes a "value style" of investing. The Adviser believes that investors overreact to short-term developments in companies, leading to opportunities to generate gains as the companies recover. The Adviser's valuation-focused process uses a dividend discount model to select stocks that trade at a discount to intrinsic value based on a company's long-term earnings power and dividend-paying capability.

In selecting securities to buy for the Fund, the Adviser combines quantitative screens with fundamental research. The Adviser first filters the Fund's universe of investable companies to companies with market capitalization of generally at least $1 billion. The Adviser's quantitative screens then rank this filtered group of companies on key value metrics, including price-to-consensus forecast earnings, price-to-book value, dividend yield and normalized earnings yields

3

(adjusted for return on invested capital). The Adviser then generally prioritizes the top 20% of the ranked companies for research. This enables the Adviser to focus its analysis on a "buy universe" of companies that appear statistically undervalued. Fundamental research is then used to develop fundamental forecasts to estimate long-term earnings power and dividend paying capability of the companies, such as revenue growth rates and operating margins. The research also considers various economic and company-specific scenarios that may affect these fundamental forecasts. These forecasts are then inputted in the Adviser's dividend discount model, which estimates the present value of future forecast dividend payments by discounting them at an appropriate interest rate. In other words, the Adviser's dividend discount model estimates what these forecasted dividend payments are worth in today's dollars. The Adviser then selects securities from the buy universe that the Adviser perceives as trading at a discount to intrinsic value as estimated by the dividend discount model. Generally, the more attractive the Adviser views the valuation upside, after taking into consideration potential risks, the larger the position size.

Further, the Adviser considers sustainability as encompassing broad environmental and other economic factors that may impact companies' long-term earnings and valuations. Sustainability risks and opportunities are evaluated in the Adviser's investment process similar to other fundamental factors. Where material and quantifiable, considerations such as sustainability impacts on costs, earnings, market share and competitive position, may affect the Adviser's assessment of company valuations.

The Adviser will generally sell a security when it moves into the bottom half of the buy universe on valuation and has a relatively low expected return to intrinsic value. Additionally, the Adviser may sell a security if its fundamentals deteriorate or if the Adviser identifies another security that the Adviser believes has a relatively more attractive discount to intrinsic value.

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.

Equity Risk - The risk that stock prices will fall over short or extended periods of time, sometimes rapidly and unpredictably. The

4

value of equity securities will fluctuate in response to factors affecting a particular company, as well as broader market and economic conditions. Broad movements in financial markets may adversely affect the price of the Fund's investments, regardless of how well the companies in which the Fund invests perform. Moreover, in the event of a company's bankruptcy, claims of certain creditors, including bondholders, will have priority over claims of common stock holders such as the Fund.

Market Risk - The prices of and the income generated by the Fund's securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations. 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. Market risk may affect a single issuer, an industry, a sector or the equity or bond market as a whole.

Active Management Risk - The Fund is subject to the risk that the Adviser's judgments about the attractiveness, value, or potential appreciation of the Fund's investments may prove to be incorrect. If the investments selected and strategies employed by the Fund fail to produce the intended results, the Fund could underperform in comparison to other funds with similar objectives and investment strategies.

Value Style Risk - The Adviser's value investment style may increase the risks of investing in the Fund. If the Adviser's assessment of market conditions, or a company's value or prospects for exceeding earnings expectations is inaccurate, the Fund could suffer losses or produce poor performance relative to other funds. In addition, "value stocks" can continue to be undervalued by the market for long periods of time.

Large Capitalization Company Risk - 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

5

capitalization companies and may not respond as quickly to market changes and opportunities.

Small and Medium Capitalization Companies Risk - The risk that small and medium capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small and medium capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small capitalization and medium capitalization stocks may be more volatile than those of larger companies. Small capitalization and medium capitalization stocks may be traded over-the-counter or listed on an exchange.

Foreign Investment/Emerging Markets Risk - The risk that non-U.S. securities may be subject to additional risks due to, among other things, political, social and economic developments abroad, currency movements, and different legal, regulatory and tax environments. These additional risks may be heightened with respect to emerging market countries because political turmoil and rapid changes in economic conditions are more likely to occur in these countries. 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.

Geographic Focus Risk - To the extent that it focuses its investments in a particular country or geographic region, the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers and countries within that country or geographic region. As a result, the Fund may be subject to greater price volatility and risk of loss than a fund holding more geographically diverse investments.

Sector and Industry Focus Risk - Because the Fund may, from time to time, be more heavily invested in particular sectors or industries, the value of its shares may be especially sensitive to factors and economic risks that specifically affect those sectors or industries. As a result, the Fund's share price may at times fluctuate more widely than the value of shares of a mutual fund that invests in a broader range of sectors or industries.

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

6

to the U.S. dollar, resulting in the dollar value of an investment in the Fund being adversely affected. Currency exchange rates may fluctuate in response to, among other things, changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities, or by the imposition of currency controls or other political developments in the United States or abroad.

Stock Connect Investing Risk - Trading through Stock Connect is subject to a number of restrictions that may affect the Fund's investments and returns, including a daily quota that limits the maximum net purchases under Stock Connect each day. In addition, investments made through Stock Connect are subject to relatively untested trading, clearance and settlement procedures. Moreover, A-Shares purchased through Stock Connect generally may only be sold or otherwise transferred through Stock Connect. The Fund's investments in A-Shares purchased through Stock Connect are generally subject to Chinese securities regulations and listing rules. While overseas investors currently are exempt from paying capital gains or value added taxes on income and gains from investments in A-Shares purchased through Stock Connect, these tax rules could be changed, which could result in unexpected tax liabilities for the Fund. Stock Connect operates only on days when both the China and Hong Kong markets are open for trading and when banks in both markets are open on the corresponding settlement days. Therefore, the Fund may be subject to the risk of price fluctuations of A-Shares when Stock Connect is not trading.

Liquidity Risk - 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. Liquidity risk may be heightened in the emerging market countries in which the Fund invests, as a result of their markets being less developed.

Depositary Receipts Risk - Depositary receipts, such as ADRs, GDRs and EDRs, are certificates evidencing ownership of shares of a foreign issuer that are issued by depositary banks and generally trade on an established market. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments.

7

Sustainability Risk - The Fund may purchase and hold securities that present sustainability risks. The evaluation of sustainability factors is often subjective and the Adviser may not identify or evaluate every relevant sustainability factor with respect to every investment. As a result, the sustainability evaluation performed by the Adviser may differ from the evaluations made by other investment advisers and may not reflect the beliefs or values of any particular investor. While the adviser may engage with companies on sustainability factors and related concerns as deemed appropriate, such engagement may not always yield positive outcomes and the adviser makes no representation that any change or improvement in a company's sustainability or related issues is or was a direct result of adviser's engagement. In addition, the evaluation of sustainability risks and opportunities and implementation of applicable sustainability-related investment restrictions (i.e., screens) rely on the availability of timely, complete and accurate sustainability data being reported by issuers and/or third-party research providers, and sustainability-related data is often based on estimates or assumptions. The Adviser's ability to evaluate and assess sustainability risks and opportunities and the successful implementation of applicable sustainability-related investment restrictions may be limited or compromised to the extent relevant data is unavailable or inaccurate. The Adviser evaluates sustainability factors that lead to potential risks or opportunities, in the same way as other financial factors. As a result, the integration of any such factor, including sustainability may lead the Fund to perform differently compared to accounts that do not integrate sustainability factors.

ETFs Risk - ETFs are pooled investment vehicles, such as registered investment companies and grantor trusts, whose shares are listed and traded on U.S. and non-U.S. stock exchanges or otherwise traded in the over-the-counter market. To the extent that the Fund invests in ETFs, the Fund will be subject to substantially the same risks as those associated with the direct ownership of the securities in which the ETF invests, and the value of the Fund's investment will fluctuate in response to the performance of the ETF's holdings. ETFs typically incur fees that are separate from those of the Fund. Accordingly, the Fund's investments in ETFs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the ETFs' operating expenses, in addition to paying Fund expenses.

Participation Notes Risk - The return on a P-Note is linked to the performance of the issuers of the underlying securities. The

8

performance of P-Notes will not replicate exactly the performance of the issuers that they seek to replicate due to transaction costs and other expenses. P-Notes are subject to counterparty risk since the notes constitute general unsecured contractual obligations of the financial institutions issuing the notes, and the Fund is relying on the creditworthiness of such institutions and has no rights under the notes against the issuers of the underlying securities. In addition, P-Notes are subject to liquidity risk, which is described elsewhere in this section.

Rights and Warrants Risk - Investments in rights or warrants involve the risk of loss of the purchase value of a right or warrant if the right to subscribe to additional shares is not exercised prior to the right's or warrant's expiration. Also, the purchase of rights and/or warrants involves the risk that the effective price paid for the right and/or warrant added to the subscription price of the underlying security may exceed the market price of the underlying security in instances such as those where there is no movement in the price of the underlying security.

Private Placements Risk - Investment in privately placed securities may be less liquid than in publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Fund or less than what may be considered the fair value of such securities. Furthermore, companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that might be applicable if their securities were publicly traded.

Preferred Stock Risk - Preferred stocks in which the Fund may invest 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.

REITs Risk - REITs are pooled investment vehicles that own, and usually operate, income-producing real estate. REITs are susceptible to the risks associated with direct ownership of real estate, such as the following: declines in property values; increases in property taxes, operating expenses, interest rates or competition; overbuilding; zoning changes; and losses from casualty or condemnation. REITs typically incur fees that are separate from those of the Fund.

9

Accordingly, the Fund's investments in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs' operating expenses, in addition to paying Fund expenses. REIT operating expenses are not reflected in the fee table and example in this prospectus.

Master Limited Partnerships (MLPs) Risk - MLPs are limited partnerships in which the ownership units are publicly traded. MLPs often own several properties or businesses (or own interests) that are related to oil and gas industries or other natural resources, but they also may finance other projects. To the extent that an MLP's interests are all in a particular industry, the MLP will be negatively impacted by economic events adversely impacting that industry. Additional risks of investing in a MLP also include those involved in investing in a partnership as opposed to a corporation, such as limited control of management, limited voting rights and tax risks. MLPs may be subject to state taxation in certain jurisdictions, which will have the effect of reducing the amount of income paid by the MLP to its investors.

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.

Valuation Risk - The sales price the Fund could receive for any particular portfolio investment may differ from the valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the security was not fair-valued or if it was valued using a different valuation methodology.

Performance Information

The bar chart and the performance table below illustrate the risks of an investment in the Fund by showing the Fund's Institutional Class Shares' performance from year to year and by showing how the Fund's average annual total returns for 1 year and since inception periods compare with those of a broad measure of market

10

performance and a more narrowly based index with characteristics relevant to the Fund's 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.

Current performance information is available on the Fund's website at https://www.argainvest.com or by calling toll-free to 866-234-ARGA (866-234-2742).

BEST QUARTER	WORST QUARTER
