Principal Investment Risks

Performance information for the Fund is not included because the Fund had not commenced operations prior to the date of this Prospectus. Performance information will be available once the Fund has at least one calendar year of performance. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future and does not guarantee future results. Updated performance information will be available on the Fund’s website at www.sgiam.com.

Loss of money is a risk of investing in the Fund.

•

Affiliated Fund Risk. Affiliated fund risk is the risk that the Adviser may select investments in other investment companies, including ETFs, for the Fund based on its own financial interests rather than the Fund’s interests. The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

•

Common Stock Risk. Investments in common stocks are subject to market, economic and business risks that will cause their price to fluctuate over time. Therefore, an investment in the Fund may be more suitable for long-term investors who can bear the risk of these fluctuations.

•

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

•

Convertible Securities Risk. Securities that can be converted into common stock, such as certain securities and preferred stock, are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to the risks associated with equity securities.

•

Counterparty Risk. Some of the derivatives entered into by the Fund are not traded on an exchange but instead will be privately negotiated in the over-the-counter market. This means that these instruments are traded between counterparties based on contractual relationships. Relying on a counterparty exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. A counterparty defaulting on its payment obligations to the Fund will cause the value of an investment in the Fund to decrease.

•

Currency Risk. Investment in foreign securities also involves currency risk associated with securities that trade or are denominated in currencies other than the U.S. dollar and which may be affected by fluctuations in currency exchange rates. An increase in the strength of the U.S. dollar relative to a foreign currency may cause the U.S. dollar value of an investment in that country to decline. Foreign currencies also are subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government controls.

•

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

•

Derivatives Risk. The Fund's investments in derivative instruments including options, forward currency exchange contracts, swaps and futures, which may be leveraged, may result in losses. Investments in derivative instruments may result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions.

•

Dividend-Paying Securities Risk. A company issuing dividend-paying securities may fail and have to decrease or eliminate its dividend. In such an event, the Fund may not only lose the dividend payout but the stock price of the company may fall.

•

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: “Authorized Participants, Market Makers and Liquidity Providers Concentration Risk,” “Cash Transactions Risk,” “Secondary Market Trading Risk,” and “Shares May Trade at Prices Other Than NAV Risk.”

o

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as authorized participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Shares. Further, the Fund is utilizing a novel and unique structure, which may affect the number of entities willing to act as APs, market makers and/or liquidity providers.

o

Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash rather than on an in-kind basis. Because of this, the Fund may incur costs such as brokerage costs or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.

o

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the The Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Fund inadvisable. These may include: (a) the extent to which trading is not occurring in the securities and/or the financial instruments composing the Fund’s Portfolio; or (b) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

o

Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. There is a risk that market prices for Fund Shares will vary significantly from the Fund’s NAV.

•

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund's holdings may change on days when shareholders are not able to purchase or redeem the Fund's shares.

•

High Portfolio Turnover Risk. The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions and cause higher levels of current tax liability to shareholders of the Fund. A portfolio turnover rate of 100% is considered to be high. For the last fiscal year, the annual portfolio turnover rate of the Fund was lower than 100%, but the Fund's portfolio turnover rate is expected to vary from year to year. The Adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

•

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund's performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

•

Large-Cap Companies Risk. The stocks of large capitalization companies as a group could fall out of favor with the market, causing the Fund to underperform investments that focus solely on small- or medium- capitalization stocks.

•

Large Shareholder Risk. Certain large shareholders, including APs, may from time to time own a substantial amount of the Fund’s shares. There is no requirement that these shareholders maintain their investment in the Fund. There is a risk that such large shareholders or that the Fund’s shareholders generally may redeem all or a substantial portion of their investments in the Fund in a short period of time, which could have a significant negative impact on the Fund’s NAV, liquidity, and brokerage costs. Large redemptions could also result in tax consequences to shareholders and impact the Fund’s ability to implement its investment strategy.

•

Leverage Risk. Leverage amplifies changes in the Fund’s NAV and may make the Fund more volatile. Derivatives may create leverage and can result in losses to the Fund that exceed the amount originally invested and may accelerate the rate of losses. There can be no assurance that the Fund’s use of any leverage will be successful. The Fund’s investment exposure can exceed its net assets, sometimes by a significant amount.

•

Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil.

•

Low Volatility Risk. Although subject to the risks of common stocks, low volatility stocks are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility stocks may not produce investment exposure that has lower variability to changes in such stocks' price levels. Investing in low volatility stocks may limit the Fund's gains in rising markets.

•

Management Risk. The Fund is subject to the risk of poor investment selection. In other words, the individual investments of the Fund may not perform as well as expected, and/or the Fund's portfolio management practices may not work to achieve their desired result.

•

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Although the Fund will invest in stocks the Adviser believes will produce less volatility, there is no guarantee that the stocks will perform as expected.

•

Mid-Cap Companies Risk. The stocks of mid-sized companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies.

•

New Fund Risk. The Fund is a newly organized, management investment company with a limited operating history. In addition, there can be no assurance that the Fund will grow to, or maintain, an economically viable size, in which case the Board of Directors (the “Board”) of The RBB Fund, Inc. (the “Company”) may determine to liquidate the Fund.

•

Options Risk. An option is a type of derivative instrument that gives the holder the right (but not the obligation) to buy (a “call”) or sell (a “put”) an asset in the near future at an agreed upon price prior to the expiration date of the option. The Fund may “cover” a call option by owning the security underlying the option or through other means. The price and value of options can be highly volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including its anticipated volatility, which are affected by national and international fiscal and monetary policies, the time remaining until the expiration of the option contract and economic events, and their use can result in loss if the Adviser is incorrect in its expectation of price fluctuations. The value of the option contracts in which the Fund invests are substantially influenced by the value of the Index, and the Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless.

•

Other Investment Company Risk. To the extent the Fund invests in other investment companies, including money market funds and ETFs, its performance will be affected by the performance of those other investment companies. Investments in other investment companies are subject to the risks of the other investment companies’ investments, as well as to the other investment companies’ expenses. An ETF may trade in the secondary market at a price below the value of its underlying portfolio and may not be liquid. An actively managed ETF’s performance will reflect its adviser’s ability to make investment decisions that are suited to achieving the ETF’s investment objectives. A passively managed ETF may not replicate the performance of the index it intends to track.

•

Price Participation Risk. The Fund employs an investment strategy that includes the sale of out-of-the-money put option contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Index over the call period (typically, one day, but may range up to one week). This means that if the Index experiences an increase in value above the strike price of the sold put options during a call period, the Fund will likely not experience that increase to the same extent and may significantly underperform the Index over the call period. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Index over each call period, but has full exposure to any decreases in value experienced by the Index over the call period, the NAV of the Fund may decrease over any given time period.

•

Referenced Index Risk. The Fund invests in options contracts that are based on the value of the Index (or in ETFs that track the Index’s performance). This subjects the Fund to certain of the same risks as if it owned shares of companies that comprised the Index or an ETF that tracks the Index, even though it does not.

•

Warrants Risk. The purchase of warrants involves the risk that the Fund could lose the purchase value of a warrant if the right to subscribe to additional shares is not executed prior to the warrant's expiration. Also, the purchase of warrants involves the risk that the effective price paid for the warrant added to the subscription price of the related security may exceed the value of the subscribed security's market price such as when there is no movement in the level of the underlying security.

This means that if the Index experiences an increase in value above the strike price of the sold put options during a call period, the Fund will likely not experience that increase to the same extent and may significantly underperform the Index over the call period. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Index over each call period, but has full exposure to any decreases in value experienced by the Index over the call period, the NAV of the Fund may decrease over any given time period.

•

Referenced Index Risk. The Fund invests in options contracts that are based on the value of the Index (or in ETFs that track the Index’s performance). This subjects the Fund to certain of the same risks as if it owned shares of companies that comprised the Index or an ETF that tracks the Index, even though it does not.

•

Bank Obligations Risk. The Fund may invest in deposits and other obligations of U.S. and non-U.S. banks and financial institutions. Investments in obligations of non-U.S. banks and financial institutions may involve risks that are different from investments in obligations of U.S. banks. These risks include future unfavorable political and economic developments, seizure or nationalization of foreign deposits, currency controls, interest limitations or other governmental restrictions that might affect the payment of principal or interest on the securities held by the Fund. All investments in deposits and other obligations are subject to credit risk, which is the risk that the Fund may lose its investments in these instruments if, for example, the issuing financial institution collapses and is unable to meet its obligations. This risk is more acute for investments in deposits and other obligations that are not insured by a government or private entity.

•

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

•

Fixed Income Risk. Fixed income securities, such as U.S. Treasuries, or derivatives based on fixed income securities, are subject to credit risk and interest rate risk. Credit risk, as described more fully herein, refers to the possibility that the issuer of a debt security will be unable to make interest payments or repay principal when it becomes due. Interest rate risk refers to fluctuations in the value of a debt security resulting from changes in the general level of interest rates. Prices of fixed income securities tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect fixed income security prices and, accordingly, the Fund’s returns and share price. In addition, the Fund may be subject to “call” risk, which is the risk that during a period of falling interest rates the issuer may redeem a security by repaying it early (which may reduce the Fund’s income if the proceeds are reinvested at lower interest rates), and “extension” risk, which occurs during a rising interest rate environment because certain obligations will be paid off by an issuer more slowly than anticipated (causing the value of those securities held by the Fund to fall).

Repurchase Agreement Risk. When the Fund enters into a repurchase agreement, the Fund is exposed to the risk that the other party (i.e., the counterparty) will not fulfill its contractual obligation. In a repurchase agreement, there exists the risk that, when the Fund buys a security from a counterparty that agrees to repurchase the security at an agreed upon price (usually higher) and time, the counterparty will not repurchase the security. These risks are magnified to the extent that a repurchase agreement is secured by collateral other than cash or U.S. government securities.

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.
