VictoryShares USAA Core Short-Term Bond ETF

Investment Objective

The VictoryShares USAA Core Short-Term Bond ETF (the "Fund") seeks high current income consistent with preservation of principal.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

¹"Other Expenses" reflect estimated expenses that the Fund expects to bear in the current fiscal year.

²Victory Capital Management Inc., the Fund's investment adviser, ("Adviser") has contractually agreed to waive its management fee and/or reimburse expenses through at least June 30, 2021 so that the total annual fund operating expenses after fee waiver and expense reimbursement (excluding certain items such as interest, taxes and brokerage commissions) do not exceed 0.35%. The Adviser is permitted to recoup advisory fees waived and expenses reimbursed by it or by the Fund's predecessor adviser for up to three years after the fiscal year in which the waiver or reimbursement took place, subject to the lesser of any operating expense limits in effect at the time of (a) the original waiver or expense reimbursement; or (b) the recoupment, after giving effect to the recoupment amount. This agreement may only be terminated by the Fund's Board of Trustees.

Fees and Expenses of the Fund (continued)

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, regardless whether or not you redeem your Shares at the end of such 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 upon these assumptions your costs would be:

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 will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. From commencement of operations, October 24, 2017, through the fiscal period ended August 31, 2018, the portfolio turnover rate of the Fund (when it was the Predecessor Fund, as defined below) was 22% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its assets in debt securities and in derivatives and other instruments that have economic characteristics similar to such securities. The Fund primarily invests in securities that have a dollar-weighted average portfolio maturity of three years or less. The debt securities in which the Fund may invest include a mix of government obligations (including U.S., state, and local governments, their agencies and instrumentalities); mortgage- and asset-backed securities (including collateralized debt obligations and collateralized mortgage obligations); corporate debt securities; and other securities believed to have debt-like characteristics. The Fund will invest primarily in investment-grade securities, but may invest up to 20% of its net assets in below-investment-grade securities, which sometimes are referred to as high-yield securities or "junk" bonds.

The Fund may not invest more than 20% of fixed-income securities (by weight of all fixed-income securities in the portfolio) in non-agency, non-government sponsored entities (GSEs), or privately issued mortgage- or asset-backed securities.

The Fund may use futures, including U.S. Treasury futures, to manage duration, increase or decrease its exposure to changing security prices or other factors that affect security values, enhance income, hedge against certain risks, or keep cash on hand to meet shareholder redemptions or other needs while maintaining exposure to a market.

Principal Risks of Investing in the Fund

Any investment involves risk, and there is no assurance that the Fund's objective will be achieved. The Fund is actively managed and the investment techniques and risk analyses used by the Fund's manager(s) may not produce the desired results. As you consider an investment in the Fund, you also should take into account your tolerance for the daily fluctuations of the financial markets and whether you can afford to leave your money in the Fund for long periods of time to ride out down periods. As with other mutual funds, losing money is a risk of investing in the Fund.

The Fund's investments are subject to the following principal risks:

n  Market Risk — Any investment involves risk, and there is no assurance that the Fund's investment objective will be achieved. Losing money is a risk of investing in the Fund. The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments, and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets, or general investor sentiment. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

VictoryShares USAA Core Short-Term Bond ETF (continued)

n  Debt Securities or Bond Risk — The Fund is subject to the risk that the market value of the bonds in the Fund's portfolio will fluctuate because of changes in interest rates, changes in the supply of and demand for debt securities, and other market factors. Bond prices generally are linked to the prevailing market interest rates. In general, when interest rates rise, bond prices fall; conversely, when interest rates fall, bond prices rise. The price volatility of a bond also depends on its duration. Generally, the longer the duration of a bond, the greater is its sensitivity to interest rates. To compensate investors for this higher interest rate risk, bonds with longer durations generally offer higher yields than bonds with shorter durations. Should the U.S. Federal Reserve raise interest rates, the Fund may be subject to risks associated with rising interest rates. The fixed-income securities in the Fund's portfolio also are subject to credit risk, which is the possibility that an issuer of a fixed-income security cannot make timely interest and principal payments on its securities or that negative market perceptions of the issuer's ability to make such payments will cause the price of that security to decline. The Fund accepts some credit risk as a recognized means to enhance an investor's return.

n  Asset-Backed and Mortgage-Backed Securities Risk — Mortgage- and asset-backed securities ("MBS" or "ABS," respectively) differ from conventional debt securities because principal is paid back over the life of the security rather than at maturity. MBS and ABS are subject to prepayment or call risk, which is the risk that a borrower's payments may be received earlier than expected due to changes in prepayment rates on underlying loans. As a result, the Fund may reinvest these early payments at lower interest rates, thereby reducing the Fund's income. These securities also are subject to extension risk, which is the risk that the life of the ABS or MBS may be extended due to higher interest rates and lower prepayments. As a result, the value of the securities will decrease. MBS also are subject to the risk of high default rates on the mortgages within the mortgage pool.The liquidity of non-agency or privately issued ABS or MBS securities, in particular those that are rated as non-investment grade, may change dramatically over time.

n  High-Yield Bond Risk — Fixed-income securities rated below investment grade, also known as "junk" or high-yield bonds, generally entail greater credit and liquidity risk than investment-grade securities. Their prices also may be more volatile, especially during economic downturns and financial setbacks or liquidity events. The Fund's value could be hurt by price declines due to actual or perceived changes in an issuer's ability to make such payments. These securities are considered by the major rating agencies to be predominantly speculative with respect to the issuer's continuing ability to pay principal and interest, and they carry a greater risk that the issuer of such securities will default on the timely payment of principal and interest. Issuers of securities that are in default or have defaulted may fail to resume principal or interest payments, in which case the Fund may lose its entire investment. The creditworthiness of issuers of these securities may be more complex to analyze than that of issuers of investment-grade debt securities, and the overreliance on credit ratings may present additional risks.

n  U.S. Government Sponsored Enterprises ("GSEs") Risk — While mortgage-backed securities, the value of which may be impacted by factors affecting the housing market, and other securities issued by certain GSEs, such as the Government National Mortgage Association ("Ginnie Mae"), are supported by the full faith and credit of the U.S. government, securities issued by other GSEs are supported only by the right of the GSE (including the Federal Home Loan Mortgage Corporation ("Freddie Mac") and the Federal National Mortgage Association ("Fannie Mae")) to borrow from the U.S. Treasury, the discretionary authority of the U.S. government to purchase the GSEs' obligations, or by the credit of the issuing agency, instrumentality, or corporation, and are neither issued nor guaranteed by the U.S. Treasury. If the GSE were to default on its obligations, the Fund might not be able to recover its investment.

n  Exchange-Traded Fund ("ETF") Structure Risk — The Fund is structured as an ETF and as a result is subject to special risks, including:

n  Not Individually Redeemable — The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

VictoryShares USAA Core Short-Term Bond ETF (continued)

n  Trading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

n  Market Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly, particularly in times of market stress. This means that Shares may trade at a premium or discount to NAV.

n  Authorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

n  Intraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV"). The IIV is not a "real-time" update of the NAV per Share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

n  Tax-Efficiency Risk — Redemptions of Shares may be effected for cash, rather than in kind, which means that the Fund may need to sell portfolio securities in order to complete an in-cash redemption, and may recognize net gains on these sales. As a result, investments in the Shares may be less tax-efficient than investments in ETFs that redeem solely or principally in kind.

n  Seed Investor or Large Shareholder Risk — Certain large shareholders, including other funds advised by the Adviser, may from time to time own a substantial amount of the Fund's Shares. In addition, seed investors, such as the Adviser, an affiliate of the Adviser, an Authorized Participant, a lead market maker, or other entity, may contribute all or a majority of the assets in the Fund to facilitate commencement of the Fund or to facilitate the Fund's achieving a specified size or scale. There is a risk that such large shareholders or seed investors may redeem their investments in the Fund, which could have a significant negative impact on the Fund's NAV, market price and brokerage costs.

n  Foreign Securities Risk — Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information, and less economic, political, and social stability in the countries in which the Fund invests. The imposition of exchange controls, sanctions, confiscations, trade restrictions (including tariffs), and other government restrictions by the United States or other governments; or problems in share registration, settlement, or custody also may result in losses. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time.

n  Derivatives Risk — Derivatives, including futures contracts, may involve risks different from, or greater than, those associated with more traditional investments. In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage, and liquidity risks. Derivatives may create leverage and expose the Fund to additional levels of risk, including greater losses from investments and increased volatility, than would otherwise have been the case had the Fund not engaged in the activities that created the leverage. As a result of investing in derivatives, the Fund could lose more than the amount it invests. Derivatives may be highly illiquid, and the Fund may not be able to close out or sell a derivative position at a particular

VictoryShares USAA Core Short-Term Bond ETF (continued)

time or at an anticipated price. Derivatives also may be subject to counterparty risk, which includes the risk that the Fund may sustain a loss as a result of the insolvency or bankruptcy of, or other non-compliance by, the other party to the transaction.

n  Liquidity Risk — The Fund is subject to liquidity risk, which is the risk that the Fund's investment may be difficult to purchase or sell and that an investment may not be sold or disposed of at an advantageous price or time.

n  Regulatory Risk — The Fund is subject to regulatory risk, which is the risk that legislative, regulatory, or tax policies or developments may have an adverse impact on the value of the Fund's investments and the Fund's NAV.

n  Management Risk — The Fund is actively managed. The Adviser's judgments about a particular security, markets, or investment strategy may prove to be incorrect and may cause the Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Performance

The bar chart and table that follow are intended to help you understand some of the risks of investing in the Fund. The bar chart shows you how the Fund's calendar year performance has varied over the past 10 years (or the life of the Fund if shorter). The table compares the Fund's average annual total returns over the same period to a broad measure of market performance. We assume reinvestment of dividends and distributions.

Performance information for the Fund prior to June 30, 2019 reflects the historical performance of the USAA Core Short-Term Bond ETF, a series of USAA ETF Trust (the predecessor to the Fund managed by USAA Asset Management Company) (the "Predecessor Fund"). The Fund's performance has not been restated to reflect any differences in expenses paid by the Predecessor Fund and those paid by the Fund.

Updated performance information is available on the Fund's website at VictorySharesLiterature.com.

Calendar Year Returns

Highest Quarter  0.89% (quarter ended December 31, 2018)

Lowest Quarter  -0.53% (quarter ended March 31, 2018)

¹ Inception date is October 24, 2017.

After-tax returns use the historical highest individual federal marginal income tax rates and do not reflect the effect of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. After-tax returns shown are not relevant if you own your Fund Shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Investment Adviser

Victory Capital Management Inc. ("Adviser") serves as the Fund's investment adviser. The portfolio managers primarily responsible for day-to-day management of the Fund are members of the Adviser's USAA Investments investment franchise.

Portfolio Managers

VictoryShares USAA Core Short-Term Bond ETF (continued)

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only in large blocks of 50,000 Shares (each block of Shares is called a "Creation Unit"). Creation Units are issued and redeemed for cash and/or in-kind for securities by Authorized Participants ("APs") that have entered into agreements with the Fund's distributor. Individual Shares may only be purchased and sold through brokers in secondary market transactions on the NYSE Arca, Inc. (the "Exchange"). Except when aggregated in Creation Units, Shares are not redeemable securities of the Fund.

Shares of the Fund will be listed for trading on the Exchange and will trade at market prices rather than NAV. Shares of the Fund may trade at a price that is greater than (a premium), at, or less than (a discount) NAV.

Tax Information

The Fund's distributions generally will be taxable as ordinary income, qualified dividend income or capital gains. A sale of Shares may result in capital gain or loss.

Payment to Broker-Dealers and Other Financial Intermediaries

If you purchase Shares 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 Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its assets in debt securities and in derivatives and other instruments that have economic characteristics similar to such securities. The Fund primarily invests in securities that have a dollar-weighted average portfolio maturity of three to ten years. The debt securities in which the Fund may invest include a mix of government obligations (including U.S., state, and local governments, their agencies and instrumentalities); mortgage- and asset-backed securities (including collateralized debt obligations and collateralized mortgage obligations); corporate debt securities; and other securities believed to have debt-like characteristics. The Fund will invest at least 35% of its net assets in government obligations under normal circumstances. The Fund will invest primarily in investment-grade securities, but may invest up to 25% of its net assets in below-investment-grade securities, which sometimes are referred to as high-yield securities or "junk" bonds.

The Fund may not invest more than 20% of fixed-income securities (by weight of all fixed-income securities in the portfolio) in non-agency, non-government sponsored entities (GSEs), or privately issued mortgage- or asset-backed securities.

The Fund may use futures, including U.S. Treasury futures, to manage duration, increase or decrease its exposure to changing security prices or other factors that affect security values, enhance income, hedge against certain risks, or keep cash on hand to meet shareholder redemptions or other needs while maintaining exposure to a market.

n  Regulatory Risk — The Fund is subject to regulatory risk, which is the risk that legislative, regulatory, or tax policies or developments may have an adverse impact on the value of the Fund's investments and the Fund's NAV.

n  Management Risk — The Fund is actively managed. The Adviser's judgments about a particular security, markets, or investment strategy may prove to be incorrect and may cause the Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Performance

The bar chart and table that follow are intended to help you understand some of the risks of investing in the Fund. The bar chart shows you how the Fund's calendar year performance has varied over the past 10 years (or the life of the Fund if shorter). The table compares the Fund's average annual total returns over the same period to a broad measure of market performance. We assume reinvestment of dividends and distributions.

Performance information for the Fund prior to June 30, 2019 reflects the historical performance of the USAA Core Intermediate-Term Bond ETF, a series of USAA ETF Trust (the predecessor to the Fund managed by USAA Asset Management Company) (the "Predecessor Fund"). The Fund's performance has not been restated to reflect any differences in expenses paid by the Predecessor Fund and those paid by the Fund.

Updated performance information is available on the Fund's website at VictorySharesLiterature.com.

Portfolio Managers

VictoryShares USAA Core Intermediate-Term Bond ETF (continued)

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only in large blocks of 50,000 Shares (each block of Shares is called a "Creation Unit"). Creation Units are issued and redeemed for cash and/or in-kind for securities by Authorized Participants ("APs") that have entered into agreements with the Fund's distributor. Individual Shares may only be purchased and sold through brokers in secondary market transactions on the NYSE Arca, Inc. (the "Exchange"). Except when aggregated in Creation Units, Shares are not redeemable securities of the Fund.

Shares of the Fund will be listed for trading on the Exchange and will trade at market prices rather than NAV. Shares of the Fund may trade at a price that is greater than (a premium), at, or less than (a discount) NAV.

Tax Information

The Fund's distributions generally will be taxable as ordinary income, qualified dividend income or capital gains. A sale of Shares may result in capital gain or loss.

Payment to Broker-Dealers and Other Financial Intermediaries

If you purchase Shares 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 Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

Additional Fund Information

USAA Core Short-Term Bond ETF ("Short-Term Bond Fund") and USAA Core Intermediate-Term Bond ETF ("Intermediate-Term Bond Fund") are each organized as an exchange-traded fund ("ETF"), each having distinct investment management objectives, strategies, risks, and policies. Together, these funds are sometimes referred to in this Prospectus as the "VictoryShares ETFs," "Victory Funds", or, more simply, the "Funds."

The following section describes additional information about the principal investment strategies that the Funds will use under normal market conditions to pursue their investment objectives, as well as any secondary strategies the Funds may use, and the related risks. This Prospectus does not attempt to describe all of the various investment techniques and types of investments that the Adviser may use in managing the Funds. The SAI includes more information about the Funds, their investments, and the related risks.

Under adverse, unstable or abnormal market conditions, a Fund may be unable to pursue or achieve its investment objective and, for temporary purposes, may invest some or all of its assets in a variety of instruments or assets, including high-quality fixed-income securities, cash and cash equivalents. For cash management purposes, each Fund may hold all or a portion of its assets in cash, short-term money market instruments or shares of other investment companies. These positions may reduce the benefit from any upswing in the market, cause a Fund to fail to meet its investment objective and increase a Fund's expenses.

Each Fund's investment objective and policy to invest at least 80% of its assets in debt securities and in derivatives and other instruments that have economic characteristics similar to such securities is non-fundamental and may be changed by the Board of Trustees upon at least 60 days' written notice to shareholders. For purposes of a Fund's 80% investment policy, "assets" means the Fund's net assets plus the amount of any borrowings for investment purposes, exclusive of collateral held from securities lending. Any derivatives counted towards the Fund's 80% policy will be valued at market value.

Investments

Information about each Fund's principal investment strategies is provided in the relevant summary section for each Fund. Below is additional information, describing in greater detail the principal investment strategies, including the practices and methodologies that the Adviser utilizes in pursuing a Fund's investment objective and principal investment strategies, as well as each Fund's principal investment risks.

The Adviser searches for securities that represent value at the time of purchase given current market conditions. Value is a combination of yield, credit quality, structure (maturity, coupon, redemption features), and liquidity. The Adviser recognizes value by simultaneously analyzing the interaction of these factors among the securities available in the market.

The Adviser will sell a security to minimize credit risk, to meet liquidity needs of the Fund, or if an attractive replacement is available.

The Funds will invest primarily in investment-grade securities, which include (a) securities issued or guaranteed by the U.S. government, its agencies and instrumentalities, (b) securities rated or subject to a guarantee that is rated within the investment-grade categories listed by at least one of the Nationally Recognized Statistical Rating Organizations ("NRSROs"), or (c) unrated securities determined by the Adviser to be of comparable quality, each at the time of purchase. Below are the current investment-grade ratings for four NRSROs:

The Short-Term Bond Fund may invest up to 20% of its net assets in below-investment-grade securities, sometimes referred to as high-yield securities or "junk" bonds, which includes distressed debt (rated CCC or higher) and defaulted securities (rated D or higher). The Intermediate-Term Bond Fund may invest up to 25% of its net assets in below-investment-grade securities and may hold bonds that become distressed or default if the Adviser believes the bonds are undervalued and could have a positive return going forward.

Each Fund may invest up to 20% of its net assets in foreign debt securities, including non-U.S. dollar-denominated securities and securities of companies in emerging market countries (i.e., those that are in the early stages of their industrial cycles). Each Fund also may invest in securities not considered foreign securities that carry foreign credit exposure.

Each Fund may invest in fixed-income securities that include mortgage- and asset-backed securities ("MBS" or "ABS"). Generally, MBS or ABS represent a pool of mortgages or other expected asset-based stream of payments, such as credit card receivables or automobile loans, which are packaged together and sold to investors. The investors then are entitled to the payments of interest and principal. Types of MBS in which the Fund may invest include, but are not limited to, collateralized mortgage obligations ("CMO"), commercial mortgage-backed securities ("CMBS"), stripped mortgage-backed securities ("SMBSs"), interest-only CMBS and mortgage dollar rolls. The Funds' investments in ABS may include asset-backed commercial paper and pass-through certificates, including equipment trust certificates ("ETC") secured by specific equipment, such as airplanes and railroad cars.

Investments (continued)

Each Fund may not invest more than 20% of its net assets in fixed-income securities (by weight of all fixed-income securities in the portfolio) of non-agency, non-government sponsored entities ("GSEs"), or privately issued MBS or ABS.

Each Fund also may invest in commodity-linked notes with principal and/or coupon payments linked to the value of particular commodities or commodity futures contracts, or a subset of commodities and commodity futures contracts.

Each Fund may use futures, including U.S. Treasury futures, to manage duration, increase or decrease its exposure to changing security prices or other factors that affect security values, to enhance income, to hedge against certain risks, or to keep cash on hand to meet shareholder redemptions or other needs while maintaining exposure to a market.

Each Fund may seek to earn additional income by lending its portfolio securities to brokers, dealers, and other financial institutions provided a number of conditions are satisfied, including that the loan be fully collateralized. Each Fund may invest securities-lending collateral in one or more unaffiliated money market funds or securities that are consistent with the Funds' investment objectives.

The Adviser may use several types of investments and investment techniques in pursuing the Funds' overall investment objective. The following describes the types of securities the Adviser may purchase or the investment techniques the Adviser may employ but which the Adviser does not consider to be a part of a Fund's principal investment strategies. Additional types of securities and strategies that the Funds may utilize are included in the Funds' Statement of Additional Information ("SAI").

Securities Lending

To enhance the return on its portfolio, the Fund may lend portfolio securities to brokers, dealers and financial institutions to realize additional income under guidelines adopted by the Board. Each loan will be secured continuously by collateral in the form of cash, high quality money market instruments or securities issued by the U.S. government or its agencies or instrumentalities.

Money Market Instruments and Repurchase Agreements

Each Fund may invest in money market instruments and repurchase agreements. A repurchase agreement represents a transaction in which a security is purchased with a simultaneous commitment to sell it back to the seller at an agreed-upon price on an agreed-upon date, the resale price of which reflects the purchase price plus an agreed-upon market rate of interest.

Risk Factors

The following describes the principal risks that you may assume as an investor in a Fund. These risks could adversely affect the net asset value, total return and the value of a Fund and your investment. The risk descriptions below provide a more detailed explanation of the principal investment risks that correspond to the risks described in each Fund's Fund Summary section of its Prospectus.

There is no assurance that a Fund will achieve its investment objective. Each Fund's Share price will fluctuate with changes in the market value of its portfolio investments. When you sell your Fund Shares, they may be worth less than what you paid for them and, accordingly, you can lose money investing in the Funds. No Fund, by itself, is intended to be a complete investment program.

n  Asset-Backed and Mortgage-Backed Securities Risk — Asset-backed securities represent interests in pools of mortgages, loans, receivables, or other assets. Mortgage-backed securities are a type of asset-backed security that represent direct or indirect participations in, or are collateralized by and payable from, mortgage loans secured by real property. Payment of interest and repayment of principal may be largely dependent upon the cash flows generated by the assets backing the securities and, in certain cases, may be supported by letters of credit, surety bonds, or other credit enhancements.

Asset-backed securities differ from conventional debt securities because principal is paid back over the life of the security rather than at maturity. A Fund may receive unscheduled prepayments of principal before the security's maturity date due to voluntary prepayments, refinancings, or foreclosures on the underlying mortgage loans. To a Fund, this means a loss of anticipated interest and a portion of its principal investment represented by any premium the Fund may have paid. In a period of rising interest rates, if a Fund holds mortgage-backed securities, it may exhibit additional volatility since individual mortgage holders are less likely to exercise prepayment options. This places additional downward pressure on the value of these securities and potentially causes the Fund to lose money. This is known as extension risk. In addition, adjustable and fixed rate mortgage-backed securities are subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of a Fund because the Fund may have to reinvest that money at the lower prevailing interest rates.

A Fund's investments in other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities, as well as additional risks associated with the nature of the assets and the servicing of those assets. Asset-backed securities may have more credit risk due to the creditworthiness of the collateral compared to mortgage assets. In the event of a default, a Fund may suffer a loss if it cannot sell collateral quickly and receive the amount it is owed. Asset-backed securities also may be subject to increased volatility and may become illiquid and more difficult to value even when there is no default or threat of default, due to market conditions impacting asset-backed securities more generally.

Asset-backed security values also may be affected by other factors including the availability of information concerning the pool and its structure, the creditworthiness of the servicing agent for the pool, the originator of the loans or receivables, or the entities providing the credit enhancement.

If a Fund purchases asset-backed, or mortgage-backed securities that are "subordinated" to other interests in the same pool of assets, the Fund as a holder of those securities could receive payments only after the pool's obligations to other investors have been satisfied. For example, an unexpectedly high rate of defaults on the mortgages held by a mortgage pool may limit substantially the pool's ability to make payments of principal or interest to a Fund as a holder of such subordinated securities, reducing the values of those securities or in some cases rendering them worthless. Certain mortgage-backed securities may include

Risk Factors (continued)

securities backed by pools of mortgage loans made to "subprime" borrowers or borrowers with blemished credit histories; the risk of defaults generally is higher in the case of mortgage pools that include such subprime mortgages. Moreover, instability in the markets for mortgage-backed and asset-backed securities, as well as the perceived financial strength of the issuer and specific restrictions on resale of the securities, may affect the liquidity of such securities, which means that it may be difficult (or impossible) to sell such securities at an advantageous time and price. As a result, the value of such securities may decrease and a Fund may have to hold these securities longer than it would like, forgo other investment opportunities, or incur greater losses on the sale of such securities than under more stable market conditions. Furthermore, instability and illiquidity in the market for lower-rated mortgage-backed and asset-backed securities may affect the overall market for such securities, thereby impacting the liquidity and value of higher-rated securities. This lack of liquidity may affect a Fund's NAV and total return adversely during the time the Fund holds these securities.

n  Debt Securities or Bond Risk — A Fund is subject to the risk that the market value of the bonds in the Fund's portfolio will fluctuate because of changes in interest rates, changes in the supply of and demand for debt securities, and other market factors. Bond prices generally are linked to the prevailing market interest rates. In general, when interest rates rise, bond prices fall; conversely, when interest rates fall, bond prices rise. For example, a bond with a duration of three years will decrease in value by approximately 3% if interest rates increase by 1%. The price volatility of a bond also depends on its duration. Generally, the longer the duration of a bond, the greater is its sensitivity to interest rates. To compensate investors for this higher interest rate risk, bonds with longer durations generally offer higher yields than bonds with shorter durations.

n  If interest rates increase, the yield of a Fund may increase and the market value of a Fund's securities may decline, adversely affecting the Fund's NAV and total return.

n  If interest rates decrease, the yield of a Fund may decrease and the market value of a Fund's securities may increase, which may increase a Fund's NAV and total return.

Although governmental financial regulators, including the U.S. Federal Reserve (the "Fed"), have taken steps to maintain historically low interest rates, there is no guarantee the Fed will maintain low interest rates in the future. Should the Fed increase interest rates, this may have unpredictable effects on markets and a Fund's investments.

The Fed's policy changes and related market speculation as to the timing of interest rate increases may expose fixed-income markets to heightened volatility and may reduce liquidity for certain Fund investments, causing the value of a Fund's investments and share price to decline. For example, market developments and other factors, including a general rise in interest rates, have the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Such a move, coupled with a reduction in the ability or willingness of dealers and other institutional investors to buy or hold fixed-income securities, may result in decreased liquidity and increased volatility in the fixed-income markets. Heavy redemptions of fixed-income mutual funds and decreased liquidity of fixed-income securities could hurt a Fund's performance.

The fixed-income securities in the Fund's portfolio also are subject to credit risk, which is the possibility that an issuer of a fixed-income security will fail to make timely interest and principal payments on its securities or that negative market perceptions of the issuer's ability to make such payments will cause the price of that security to decline. All fixed-income securities ranging from the highest quality to the very speculative have some degree of credit risk. Each Fund accepts some credit risk as a recognized means to enhance investors' return. To the extent a Fund invests in government securities, credit risk will be limited.

Risk Factors (continued)

When evaluating potential investments for a Fund, our analysts independently assess credit risk and its potential impact on the Fund's portfolio. In addition, the credit rating agencies may provide estimates of the credit quality of the securities. The ratings may not take into account every risk that interest or principal will be repaid on a timely basis. Lower credit ratings typically correspond to higher credit risk, and higher credit ratings typically correspond to lower perceived risk. Credit ratings do not provide assurance against default or other loss of money. The Adviser attempts to minimize a Fund's overall credit risk by primarily investing in fixed-income securities considered at least investment grade at the time of purchase and diversifying a Fund's investments across many securities with slightly different risk characteristics, economic sectors, and geographic regions. If a random credit event should occur, such as a default, a Fund generally would suffer a smaller loss than if the Fund were concentrated in relatively large holdings with highly correlated risks.

n  Derivatives Risk — Derivatives, such as futures contracts, are subject to the risk that small price movements can result in substantial gains or losses. Derivatives also entail exposure to counterparty risk, the risk of mispricing or improper valuation and the risk that changes in value of the derivative may not correlate perfectly with the relevant securities, assets or indices. The Fund "covers" its exposure to certain derivative contracts by segregating or designating liquid assets on its records sufficient to satisfy current payment obligations, which may expose the Fund to the market through both the underlying assets subject to the contract and the assets used as cover. The use of derivatives could expose a Fund to the effects of leverage causing the Fund to lose more money than it invested. There is no guarantee that derivatives activities will be employed or that they will work, and their use could lower returns or even result in losses to the Fund. Derivatives also may be harder to value, less tax-efficient, and subject to changing government regulation that could impact the Fund's ability to use certain derivatives or their cost.

n  Exchange-Traded Fund ("ETF") Structure Risk — Each Fund is structured as an ETF and as a result is subject to special risks, including:

n  Not Individually Redeemable — Shares are not individually redeemable and may be redeemed by a Fund at NAV only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

n  Trading Issues — Although the Shares are listed on the Exchange, there can be no assurance that an active, liquid or otherwise orderly trading market for Shares will be established or maintained by market makers or Authorized Participants, particularly in times of stressed market conditions. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for a Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

n  Market Price Variance Risk — Individual Shares of a Fund that are listed for trading on the Exchange can be bought and sold in the secondary market at market prices. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares. There may be times when the market price and the NAV vary significantly and you may pay more than NAV when buying Shares on the secondary market (a premium), and you

Risk Factors (continued)

may receive less than NAV when you sell those Shares (a discount). The market price of Shares, like the price of any exchange-traded security, includes a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. In times of severe market disruption, the bid-ask spread often increases significantly. This means that Shares may trade at a discount to NAV and the discount is likely to be greatest when the price of Shares is falling fastest, which may be the time that you most want to sell your Shares. A Fund's investment results are measured based upon the daily NAV of a Fund over a period of time. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by those creating and redeeming directly with a Fund.

n  International Closed Market Trading Risk — A Fund's underlying securities may trade on foreign exchanges that are closed when the Exchange is open; consequently, events may transpire while such foreign exchanges are closed but the Exchange is open that may change the value of such underlying securities relative to their last quoted prices on such foreign exchanges. Because a Fund generally relies on the last quoted prices for such securities when calculating its NAV, such events may cause Shares to trade at a premium or discount to NAV.

n  Authorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for a Fund. In addition, there is no obligation for market makers to make a market in a Fund's shares or for Authorized Participants to submit purchase or redemption orders for Creation Units. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

n  Intraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of a Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of a Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. For securities traded outside of the U.S., the IIV calculations are based on local market prices and may not reflect events that occur subsequent to the local market's close which could affect premiums and discounts between the IIV and the market price of a Fund's Shares. In addition, the IIV is based on the published Deposit Securities and not on a Fund's actual holdings. A Fund, the Adviser and their affiliates are not involved in, or responsible for, any aspect of the calculation or dissemination of the IIV and make no warranty as to the accuracy of these calculations.

n  Tax-Efficiency Risk — Redemptions of shares may be effected for cash, rather than in kind, which means that the Fund may need to sell portfolio securities in order to complete an in-cash redemption, and may recognize net gains on these sales. As a result, investments in the shares may be less tax-efficient than investments in ETFs that redeem solely or principally in kind.

n  Foreign Investing Risk — Foreign investing risk is the possibility that the value of a Fund's investments in foreign securities will decrease because of currency exchange-rate fluctuations; foreign market illiquidity; emerging-market risk; increased price volatility; uncertain political conditions; exchange control regulations; foreign ownership limits; different accounting, reporting, and disclosure requirements; less publicly available information about foreign issuers; difficulties in obtaining legal judgments; and foreign withholding taxes, among other challenges on non-U.S. investments. Foreign investing may result in a Fund experiencing more rapid and extreme changes in value than a fund that

Risk Factors (continued)

invests exclusively in securities of U.S. companies. Foreign investments may be more difficult to value than U.S. securities. Risks that require additional consideration are:

n  Currency Risk — Investments in foreign currencies and in securities that trade in, or receive revenues in, or in derivatives that provide exposure to, foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar. Any such decline may erode or reverse any potential gains from an investment in securities denominated in foreign currency or may widen existing loss. Currency rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates; intervention (or the failure to intervene) by governments, central banks or supranational entities; the imposition of currency controls; or other political developments in the United States or abroad.

n  Depositary Receipts Risk — Foreign securities may trade in the form of depositary receipts, which include ADRs and GDRs (collectively "Depositary Receipts"). To the extent the Fund acquires Depositary Receipts through banks that do not have a contractual relationship with the foreign issuer of the security underlying the Depositary Receipts to issue and service such unsponsored Depositary Receipts, the Fund may not become aware of and be able to respond to corporate actions such as stock splits or rights offerings involving the foreign issuer in a timely manner. In addition, the lack of information may result in inefficiencies in the valuation of such instruments. Investment in Depositary Receipts does not eliminate all the risks inherent in investing in securities of non-U.S. issuers. The market value of Depositary Receipts is dependent upon the market value of the underlying securities and fluctuations in the relative value of the currencies in which the Depositary Receipts and the underlying securities are quoted.

n  Emerging-Markets Risk — Investments in countries that are in the early stages of their industrial development involve exposure to economic structures that generally are less economically diverse and mature than those in the United States, and to political systems that may be less stable. Investments in emerging markets may be subject to the risk of abrupt and severe price declines and their financial markets often lack liquidity. In addition, emerging-market countries may be more likely than developed countries to experience rapid and significant adverse developments in their political or economic structures. Emerging-market economies also may be overly reliant on particular industries, and more vulnerable to shifts in international trade, trade barriers, and other protectionist or retaliatory measures. Governments in many emerging-market countries participate to a significant degree in their economies and securities markets. Some emerging-market countries restrict foreign investments, impose high withholding or other taxes on foreign investments, impose restrictive exchange control regulations, or may nationalize or expropriate the assets of private companies. Emerging-market countries also may be subject to high inflation and rapid currency devaluations and currency-hedging techniques may be unavailable in certain emerging-market countries.

n  Political Risk — Political risk includes a greater potential for coups d'état, revolts, and expropriation by governmental organizations.

n  European Economic Risk — In June 2016, the United Kingdom ("UK") approved a referendum to leave the European Union ("EU"), commonly referred to as "Brexit." The impact of Brexit is so far uncertain. The effect on the UK's economy will likely depend on the nature of trade relations with the EU following its exit. On March 29, 2017, Prime Minister Theresa May provided formal notification of the UK's intention to withdraw from the EU pursuant to Article 50 of the Treaty of Lisbon. While the UK is scheduled to leave the EU, no date is certain at this time. The UK's decision to leave the EU may cause increased volatility and have a significant adverse impact for some time on world financial markets, other international trade agreements, and the UK and European economies, as well as the broader global economy.

Risk Factors (continued)

n  High-Yield Bond Risk — Fixed-income securities rated below investment grade, also known as "junk" or high-yield bonds, generally entail greater credit and liquidity risk than investment-grade securities. Their prices also may be more volatile, especially during economic downturns and financial setbacks or liquidity events. The Fund's value could be hurt by price declines due to actual or perceived changes in an issuer's ability to make such payments. These securities are considered by the major rating agencies to be predominantly speculative with respect to the issuer's continuing ability to pay principal and interest and carry a greater risk that the issuer of such securities will default in the timely payment of principal and interest. Issuers of securities that are in default or have defaulted may fail to resume principal or interest payments, in which case the Fund may lose its entire investment. The creditworthiness of issuers of these securities may be more complex to analyze than that of issuers of investment-grade debt securities, and the overreliance on credit ratings may present additional risks.

n  Liquidity Risk — Certain securities held by a Fund may be difficult (or impossible) to buy or sell at the time and at the price the Fund would like due to a variety of factors, including general market conditions, the perceived financial strength of the issuer, specific restrictions on resale of the securities, infrequent trading, or lack of market participants. Liquidity is a general investment risk that potentially could impact any security, but funds that invest in privately placed securities, certain small-company securities, high-yield bonds, certain mortgage-backed or asset-backed securities, foreign or emerging market securities, derivatives, or other structured investments, which all have experienced periods of illiquidity, generally are subject to greater liquidity risk than funds that do not invest in these types of securities. The Fund also may experience reduced liquidity if it has unusually high redemption requests. Reduced liquidity means that the Fund may have difficulty meeting redemptions requests, be unable to achieve its desired level of exposure to a certain market or sector, need to dispose of certain securities, or forgo investment opportunities. It also could adversely impact the valuation of certain securities. In addition, reduced liquidity could impact the Fund's performance negatively.

n  Management Risk — Each Fund is subject to management risk, which is the possibility that the investment techniques and risk analyses used in managing a Fund's portfolio will not produce the desired results.

n  Market Risk — Any investment involves risk, and there is no assurance that the Fund's investment objective will be achieved. Losing money is a risk of investing in the Fund. The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments, and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets, or general investor sentiment. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value. In addition, markets and market participants are increasingly reliant upon both publicly available and proprietary information data systems. Data imprecision, software or other technology malfunctions, programming inaccuracies, unauthorized use or access, and similar circumstances may impair the performance of these systems and may have an adverse impact upon a single issuer, a group of issuers, or the market at large. In certain cases, an exchange or market may close or issue trading halts on either specific securities or even the entire market, which may result in a Fund being, among other things, unable to buy or sell certain securities or financial instruments or accurately price its investments.

Market turmoil may be reflected in perceptions of economic uncertainty, price volatility in the equity and debt markets, and fluctuating trading liquidity. In response, governments may adopt a variety of fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs, and lower interest rates. An unexpected or quick reversal of these policies could increase volatility in the equity and debt

Risk Factors (continued)

markets. Market conditions and economic risks could have a significant effect on domestic and international economies and could add significantly to the risks of increased volatility for a Fund. Equity securities tend to be more volatile than debt securities.

n  Regulatory Risk — Each Fund is subject to regulatory risk, which is the risk that legislative, regulatory, or tax policies or developments may have an adverse impact on the value of the Fund's investments and the Fund's NAV.

n  Seed Investor or Large Shareholder Risk — Certain large shareholders, including other funds advised by the Adviser, may from time to time own a substantial amount of the Fund's shares. In addition, seed investors, such as the Adviser, an affiliate of the Adviser, an Authorized Participant, a lead market maker, or other entity, may contribute all or a majority of the assets in the Fund to facilitate commencement of the Fund or to facilitate the Fund's achieving a specified size or scale. To the extent a seed investor in the Fund is an entity subject to domestic and/or international banking regulations, changes in those regulations (e.g., capital requirements) or in the seed investor's financial status may cause or require the seed investor to redeem its investment in the Fund when it otherwise would not choose to redeem that investment. There is a risk that such large shareholders or seed investors may redeem their investments in the Fund, which could have a significant negative impact on the Fund's NAV, market price, and brokerage costs.

n  U.S. Government Sponsored Enterprises ("GSEs") Risk — While mortgage-backed securities, the value of which may be impacted by factors affecting the housing market, and other securities issued by certain GSEs, such as Government National Mortgage Association ("Ginnie Mae"), are supported by the full faith and credit of the U.S. government, securities issued by other GSEs are supported only by the right of the GSE (including Federal Home Loan Mortgage Corporation ("Freddie Mac") and Federal National Mortgage Association ("Fannie Mae")) to borrow from the U.S. Treasury, the discretionary authority of the U.S. government to purchase the GSEs' obligations, or by the credit of the issuing agency, instrumentality, or corporation, and are neither issued nor guaranteed by the U.S. Treasury. If the GSE were to default on its obligations, a Fund might not be able to recover its investment. It is possible that actions by the U.S. Treasury or others could adversely impact the value of a Fund's investments in securities issued by Fannie Mae and Freddie Mac.

The Adviser may use several types of investments in furtherance of the Fund's overall investment objective. The following risks are those that the Adviser does not consider to be principal risks of the Fund. Additional risks are included in the Fund's SAI.

n  Securities Lending Risk — The risk in lending portfolio securities, as with other extensions of credit, consists of the possibility of loss to a Fund due to (i) the inability of the borrower to return the securities, (ii) a delay in receiving additional collateral to adequately cover any fluctuations in the value of securities on loan, (iii) a delay in recovery of the securities, or (iv) the loss of rights in the collateral should the borrower fail financially. In addition, each Fund is responsible for any loss that might result from its investment of the borrower's collateral. In determining whether to lend securities, the Adviser or the Funds' securities lending agent will consider relevant facts and circumstances, including the creditworthiness of the borrower.

n  Repurchase Agreement Risk — Repurchase agreements carry several risks. Although transactions must be fully collateralized at all times, they generally create leverage and involve some counterparty risk to a Fund, in that a defaulting counterparty could delay or prevent a Fund's recovery of collateral. For example, if the other party to a repurchase agreement defaults on its obligation under the agreement, a Fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security and the market value of the security declines, a Fund may suffer a loss to the extent that the proceeds from the sale of the underlying securities and other collateral held by a Fund are less than the repurchase price.

Management of the Funds

Share Price

Share Price (continued)

How to Buy and Sell Shares

Shares of each Fund will be listed for trading on the Exchange under the ticker symbols listed on the cover of this Prospectus. Share prices are reported in dollars and cents per Share. Shares can be bought and sold on the secondary market throughout the trading day like other publicly traded shares, and shares typically trade in blocks of less than a Creation Unit. There is no minimum investment required. Shares may only be purchased and sold on the secondary market when the Exchange is open for trading. The Exchange is open for trading Monday through Friday and is closed on weekends and the following holidays, as observed: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

When buying or selling Shares through a broker, you will incur customary brokerage commissions and charges. The commission is often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell smaller amounts of Shares. You may also pay some or all of the spread between the bid and the offered price in the secondary market on each leg of a round trip (purchase and sale) transaction. The spread varies over time for shares of the Fund based on the Fund's trading volume and market liquidity, and is generally lower if a Fund's Shares have more trading volume and market liquidity and higher if a Fund's Shares have little trading volume and market liquidity.

Only an Authorized Participant ("AP") may engage in creation or redemption transactions directly with the Fund. The Funds' APs are institutions and large investors, such as market makers or other large broker-dealers, which have entered into a Participation Agreement with the Funds' Distributor to undertake the responsibility of obtaining or selling the underlying assets needed to purchase or redeem, respectively, Creation Units of the Funds. APs may acquire Shares directly from a Fund, and APs may tender their Shares for redemption directly to a Fund, at NAV per share only in large blocks, or Creation Units, of 50,000 shares. Purchases and redemptions directly with a Fund must follow the Funds' procedures, which are described in the SAI.

The Funds may liquidate and terminate at any time without shareholder approval.

Share Trading Prices

The trading prices of a Fund's Shares in the secondary market generally differ from the Fund's daily NAV and are affected by market forces such as the supply of and demand for ETF shares and shares of underlying securities held by the Fund, economic conditions and other factors. Information regarding the intraday indicative value ("IIV") of a Fund will be disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund's shares are primarily listed or by market data vendors or other information providers. The IIV is based on the current market value of the securities and/or cash included in a Fund's published basket of securities. However, the IIV should not be viewed as a "real-time" update of the NAV per share of a Fund because the approximate value may not be calculated in the same manner as the NAV, which is computed once a day, generally at the end of the business day. The IIV does not necessarily reflect the precise composition of the current portfolio of securities and instruments held by a Fund at a particular point in time or the best possible valuation of the current portfolio. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV may not reflect estimated accrued interest, dividends and other income, or Fund expenses. The IIV generally is determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities and instruments included in a Fund's IIV basket. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Funds are not involved in, or responsible for, the calculation or dissemination of the approximate value of the Shares and the Funds do not make any warranty as to the accuracy of these values.

How to Buy and Sell Shares (continued)

Book Entry

Shares are held in book entry form, which means that no stock certificates are issued. The Depository Trust Company ("DTC") or its nominee is the record owner of all outstanding Shares of the Funds and is recognized as the owner of all Shares for all purposes.

Investors owning shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for all shares. Participants in DTC include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book entry or "street name" form.

Frequent Purchases and Redemptions of Fund Shares

Each Fund's Shares can only be purchased and redeemed directly from a Fund by APs in Creation Units. Direct trading by APs is critical to ensuring that a Fund's Shares trade at or close to NAV. The cash to be contributed to (or received from) the Fund in connection with a Creation Unit generally is negligible compared to the total amount of the trade. The Funds with exposure to non-U.S. securities employ fair valuation pricing to minimize arbitrage opportunities that attempt to exploit the differences between a security's market quotation and its fair value. In addition, the Funds impose transaction fees on purchases and redemptions of Shares to cover the custodial and other costs incurred by the Funds in effecting trades. These fees increase if an investor substitutes cash in part or in whole for securities, reflecting the fact that a Fund's trading costs increase in those circumstances.

The vast majority of trading in a Fund's Shares occurs on the secondary market. Because the secondary market trades do not directly involve the Funds, it is unlikely those trades would cause the harmful effects of market timing, including dilution, disruption of portfolio management, increases in a Fund's trading costs and the realization of capital gains.

Given this structure, the Board has determined that it is not necessary to monitor for frequent in-kind purchases and redemptions of Shares or market timing activity by the APs or on the Shares' secondary market.

Other Payments to Financial Intermediaries

If you purchase Fund shares through an investment professional, a broker dealer, or other financial intermediary, the Fund may pay for sub-transfer agent, recordkeeping and/or similar administrative services. In addition, Victory Capital (and its affiliates) may make substantial payments out of its own resources, including the profits from the advisory fees Victory Capital receives from the Funds, to affiliated and unaffiliated dealers or other investment professionals and service providers for distribution, administrative and/or shareholder servicing activities. Victory Capital also may reimburse the Distributor (or the Distributor's affiliates) for making these payments. Some of these distribution-related payments may be made to dealers or other investment professionals for marketing, promotional or related expenses; these payments are often referred to as "revenue sharing." In some circumstances, these types of payments may create an incentive for a dealer or investment professional or its representatives to recommend or offer shares of the Funds to its customers. You should ask your dealer or investment professional for more details about any such payments it receives.

Distribution and Service Plan

The Funds have adopted a distribution and service plan ("Plan") pursuant to Rule 12b-1 under the 1940 Act. Under the Plan, the Funds are authorized to pay distribution fees to the distributor and other firms that provide distribution and shareholder services ("Service Providers"). If a Service Provider provides these services, the Funds may pay fees at an annual rate not to exceed 0.25% of average daily net assets, pursuant to Rule 12b-1 under the 1940 Act.

No distribution or service fees are currently paid by the Funds and there are no current plans to impose these fees. In the event Rule 12b-1 fees were charged, over time they would increase the cost of an investment in the Funds.

Distributions and Taxes

Unlike interests in conventional mutual funds, which typically are bought and sold from and to a fund only at closing NAVs, each Fund's Shares are traded throughout the day in the secondary market on a national securities exchange on an intra-day basis and are created and redeemed in-kind and/or for cash in Creation Units at each day's next calculated NAV. In-kind arrangements are designed to protect ongoing shareholders from the adverse effects on a Fund's portfolio that could arise from frequent cash redemption transactions. In a conventional mutual fund, redemptions can have an adverse tax impact on taxable shareholders if the mutual fund needs to sell portfolio securities to obtain cash to meet net fund redemptions. These sales may generate taxable gains for the ongoing shareholders of the mutual fund, whereas the Shares' in-kind redemption mechanism generally will not lead to a tax event for the Fund or its ongoing shareholders.

Ordinarily, dividends from net investment income, if any, are declared and paid monthly by each Fund. Each Fund distributes its net realized capital gains, if any, to shareholders annually.

Distributions in cash may be reinvested automatically in additional whole shares only if the broker through whom you purchased shares makes such option available.

As with any investment, you should consider how your investment in shares will be taxed. The tax information in this Prospectus is provided as general information. You should consult your own tax professional about the tax consequences of an investment in shares.

Unless your investment in shares is made through a tax-exempt entity or tax-deferred retirement account, such as an individual retirement account, you need to be aware of the possible tax consequences when:

n  A Fund makes distributions,

n  You sell your shares listed on the Exchange, and

n  You purchase or redeem Creation Units.

Taxes on Distributions

As stated above, each Fund ordinarily declares and pays dividends from net investment income, if any, monthly. The Funds may also pay a special distribution at the end of a calendar year to comply with federal tax requirements. Distributions from a Fund's net investment income, including net short-term capital gains, if any, are taxable to you as ordinary income, except that a Fund's dividends attributable to its "qualified dividend income" (i.e., dividends received on stock of most domestic and certain foreign corporations with respect to which a Fund satisfies certain holding period and other restrictions), if any, generally are taxable to non-corporate shareholders at preferential rates. A part of a Fund's dividends also may be eligible for the dividends-received deduction allowed to corporations, subject to similar restrictions.

In general, your distributions are subject to federal income tax when they are paid, whether you take them in cash or reinvest them in a Fund (if that option is available). Distributions reinvested in additional shares of a Fund through the means of a dividend reinvestment service, if available, will be taxable to shareholders acquiring the additional shares to the same extent as if such distributions had been received in cash. Distributions of net long-term capital gains, if any, in excess of net short-term capital losses are taxable as long-term capital gains (at the 20% maximum rate referred to above for non-corporate shareholders), regardless of how long you have held the shares.

Distributions in excess of a Fund's current and accumulated earnings and profits are treated as a tax-free return of capital to the extent of your basis in the shares and as capital gain thereafter. A distribution will reduce a Fund's NAV per Share and may be taxable to you

Distributions and Taxes (continued)

as ordinary income or capital gain (as described above) even though, from an investment standpoint, the distribution may constitute a return of capital.

By law, the Funds are required to withhold 24% of your distributions and redemption proceeds if you have not provided the Funds with a correct Social Security number or other taxpayer identification number and in certain other situations.

Taxes on Exchange-Listed Share Sales

Any capital gain or loss realized upon a sale of shares is generally treated as long-term capital gain or loss if the shares have been held for more than one year and as short-term capital gain or loss if the shares have been held for one year or less. The ability to deduct capital losses from sales of shares may be limited.

Taxes on Purchase and Redemption of Creation Units

An AP who exchanges securities for Creation Units generally will recognize a gain or a loss equal to the difference between the market value of the Creation Units at the time of the exchange and the sum of the exchanger's aggregate basis in the securities surrendered plus any Cash Component it pays. An AP who exchanges Creation Units for securities will generally recognize a gain or loss equal to the difference between the exchanger's basis in the Creation Units and the sum of the aggregate market value of the securities received plus any cash equal to the difference between the NAV of the shares being redeemed and the value of the securities. The Internal Revenue Service ("Service"), however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing "wash sales" or for other reasons. Persons exchanging securities should consult their own tax advisor with respect to whether wash sale rules apply and when a loss might be deductible.

Any capital gain or loss realized upon redemption of Creation Units is generally treated as long-term capital gain or loss if the shares have been held for more than one year and as short-term capital gain or loss if the shares have been held for one year or less.

If you purchase or redeem Creation Units, you will be sent a confirmation statement showing how many shares you purchased or sold and at what price. See "Taxes" in the SAI for a description of the requirement regarding basis determination methods applicable to Share redemptions and the Fund's obligation to report basis information to the Service.

The foregoing discussion summarizes some of the possible consequences under current federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. Consult your personal tax advisor about the potential tax consequences of an investment in the shares under all applicable tax laws.

Other Information

Investments by Investment Companies

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies, including Shares of the Funds. Registered investment companies are permitted to invest in the Funds beyond the limits set forth in Section 12(d)(1) subject to certain terms and conditions set forth in an SEC exemptive order issued to the Adviser, including that such investment companies enter into an agreement with the Trust on behalf of the Funds.

Continuous Offering

The method by which Creation Units of Shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Units of Shares are issued and sold by the Funds on an ongoing basis, a "distribution," as such term is used in the Securities Act of 1933, as amended (the "Securities Act"), may occur at any point. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent Shares and sells the Shares directly to customers or if it chooses to couple the creation of a supply of new Shares with an active selling effort involving solicitation of secondary market demand for Shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a characterization as an underwriter.

Broker-dealer firms should also note that dealers who are not "underwriters" but are effecting transactions in Shares, whether or not participating in the distribution of Shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. As a result, broker-dealer firms should note that dealers who are not "underwriters" but are participating in a distribution (as contrasted with engaging in ordinary secondary market transactions) and thus dealing with the Shares that are part of an overallotment within the meaning of Section 4(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the Securities Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the Securities Act is only available with respect to transactions on a national exchange.

Dealers effecting transactions in the Funds' Shares, whether or not participating in this distribution, are generally required to deliver a Prospectus. This is in addition to any obligation of dealers to deliver a Prospectus when acting as underwriters.

VictoryShares USAA MSCI USA Value Momentum ETF

Investment Objective

The VictoryShares USAA MSCI USA Value Momentum ETF (the "Fund") seeks to provide investment results that closely correspond, before fees and expenses, to the performance of the MSCI USA Select Value Momentum Blend Index (the "Index").

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

¹"Other Expenses" reflect estimated expenses that the Fund expects to bear in the current fiscal year.

²Victory Capital Management Inc., the Fund's investment adviser, ("Adviser") has contractually agreed to waive its management fee and/or reimburse expenses through at least June 30, 2021 so that the total annual fund operating expenses after fee waiver and expense reimbursement (excluding certain items such as interest, taxes and brokerage commissions) do not exceed 0.20%. The Adviser is permitted to recoup advisory fees waived and expenses reimbursed by it or by the Fund's predecessor adviser for up to three years after the fiscal year in which the waiver or reimbursement took place, subject to the lesser of any operating expense limits in effect at the time of (a) the original waiver or expense reimbursement; or (b) the recoupment, after giving effect to the recoupment amount. This agreement may only be terminated by the Fund's Board of Trustees.

VictoryShares USAA MSCI USA Value Momentum ETF (continued)

Fees and Expenses of the Fund (continued)

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, regardless whether or not you redeem your Shares at the end of such periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

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 will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. From commencement of operations, October 24, 2017, through the fiscal period ended August 31, 2018, the portfolio turnover rate of the Fund (when it was the Predecessor Fund, as defined below) was 84% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund seeks to achieve its investment objective by investing at least 80% of its assets in securities in the Index. MSCI, Inc. (the "Index Provider") constructs the Index in accordance with a rules-based methodology.

The Index is designed to deliver exposure to equity securities of large- and mid-capitalization U.S. issuers within the MSCI USA Index (the "Parent Index") that have higher exposure to value and momentum factors, while also maintaining moderate Index turnover and lower realized volatility than traditional capitalization-weighted indexes. The value factor indicates how attractively a stock is priced relative to its fundamentals, such as book value and free cash flow. A value score is derived from a company's valuation ratios, e.g. forward price to earnings, share price to book value, and enterprise value to operating cash flow. The momentum factor indicates whether changes in a company's share price are trending up or down. A momentum score is calculated using a security's price trends over the last six months and twelve months (except the previous month), adjusted for volatility. A security is only evaluated within a single sector.

The Index Provider ranks each stock of the Parent Index based on its value and momentum scores, relative to their sector classification, and creates a composite score for each stock by equally weighting the stock's value and momentum score. The Index Provider then selects the top 25% of the ranked stocks of the Parent Index based on their composite scores for inclusion in the Index. The constituents are weighted such that securities with lower realized volatility are given higher Index weights. The Index rebalances quarterly. As of December 31, 2018, the market capitalization of the issuers in the Index ranged from $3.0 billion to $778.9 billion. The range may change from time to time.

The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index. The Fund also may invest up to 20% of its assets in instruments other than the securities in the Index, which the Adviser believes will help the Fund track the Index. Such instruments may include derivatives, including index futures, which the Fund may use for cash management (attempting to remain fully invested while maintaining liquidity) or to gain exposure to an investment in a manner other than investing in the asset directly.

The Fund will concentrate its investments (i.e., hold more than 25% of its assets) in a particular industry or group of industries to the extent that its Index is concentrated. The degree to which certain sectors, industries, or asset classes are represented in the Index may change over time.

VictoryShares USAA MSCI USA Value Momentum ETF (continued)

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

n  Market Risk — Any investment involves risk, and there is no assurance that the Fund's investment objective will be achieved. Losing money is a risk of investing in the Fund. The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments, and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets, or general investor sentiment. Individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

n  Index Risk — The Fund attempts to track the performance of a specific index. The Fund will be negatively affected by general declines in the securities and asset classes represented in the Index. In addition, because the Fund is not "actively" managed, unless a specific security is removed from the Index, the Fund generally would not sell a security because the security's issuer was in financial trouble. The Fund also does not attempt to take defensive positions under any market conditions, including declining markets. Therefore, the Fund's performance could be lower than funds that may actively shift their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline or a decline in the value of one or more issuers.

n  Tracking Error Risk — Tracking error is the divergence of the Fund's performance from that of the Index. The performance of the Fund may diverge from that of its Index for a number of reasons, such as the use of representative sampling (if applicable), transaction costs, the Fund's holding of cash, differences in accrual of dividends, changes to the Index, tax considerations, rebalancing, or new or existing regulatory requirements. Unlike the Fund, the returns of the Index are not reduced by investment and other operating expenses, including the trading costs associated with implementing changes to its portfolio of investments. Tracking error risk may be heightened during times of market volatility or other unusual market conditions. To the extent that the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities' closing prices (i.e., the value of the Index is not based on fair value prices), the Fund's ability to track the Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities to realize losses, which will result in a deviation from the Index.

n  Momentum Risk — Momentum investing entails investing more in securities that exhibit persistence in relative performance evidenced by better recent price performance compared to other securities. These securities may be more volatile than a broad cross-section of securities, and momentum may be an indicator that a security's price is peaking. Momentum can turn quickly and cause significant variation from other types of investments. The Fund may experience significant losses if momentum stops, turns or otherwise behaves differently than predicted.

n  Value Risk — Value investing entails investing in securities that are inexpensive relative to other securities based on ratios such as price to earnings or price to book. There may be periods when value investing is out of favor, and during which the investment performance of a fund using a value strategy may suffer. In addition, value stocks are subject to the risk that their intrinsic value may never be realized in the market.

n  Mid-Capitalization Company Risk — Investments in mid-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

n  Large-Capitalization Company Risk — Investments in large-capitalization companies may go in and out of favor based on market and economic conditions and may underperform other market segments. Some large-capitalization companies may be unable to respond quickly to new competitive challenges and attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion. As such, returns on investments in stocks of large-capitalization companies could trail the returns on investments in stocks of small- and mid-capitalization companies.

VictoryShares USAA MSCI USA Value Momentum ETF (continued)

n  Seed Investor or Large Shareholder Risk — Certain large shareholders, including other funds advised by the Adviser, may from time to time own a substantial amount of the Fund's Shares. In addition, seed investors, such as the Adviser, an affiliate of the Adviser, an Authorized Participant, a lead market maker, or other entity, may contribute all or a majority of the assets in the Fund to facilitate commencement of the Fund or to facilitate the Fund's achieving a specified size or scale. There is a risk that such large shareholders or seed investors may redeem their investments in the Fund, which could have a significant negative impact on the Fund's NAV, market price and brokerage costs.

n  Concentration Risk — In following its methodology, the Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Index concentrates in the securities of issuers in a particular industry or sector, the Fund also can be expected to concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund may face more risks than if it were diversified broadly over numerous industries or sectors. If the Index is not concentrated in a particular industry or sector, the Fund will not concentrate in a particular industry or sector.

n  Exchange-Traded Fund ("ETF") Structure Risk — The Fund is structured as an ETF and as a result is subject to special risks, including:

n  Not Individually Redeemable — The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

n  Trading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

n  Market Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly, particularly in times of market stress. This means that Shares may trade at a premium or discount to NAV.

n  Authorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

n  Intraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV"). The IIV is not a "real-time" update of the NAV per Share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

n  Liquidity Risk — The Fund is subject to liquidity risk, which is the risk that the Fund's investment may be difficult to purchase or sell and that an investment may not be sold or disposed of at an advantageous price or time.

VictoryShares USAA MSCI USA Value Momentum ETF (continued)

n  Valuation Risk — The sale price the Fund could receive for a security may differ from the Fund's valuation of the security and may differ from the value used by the Index, particularly for securities that trade in low volume or volatile markets or that are valued using a fair value methodology. The Fund relies on various sources to calculate its NAV. The information may be provided by third parties that are believed to be reliable, but the information may not be accurate due to errors by such pricing sources, technological issues, or otherwise.

n  Derivatives Risk — Derivatives, including futures contracts, may involve risks different from, or greater than, those associated with more traditional investments. In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage, and liquidity risks. Derivatives may create leverage and expose the Fund to additional levels of risk, including greater losses from investments and increased volatility, than would otherwise have been the case had the Fund not engaged in the activities that created the leverage. As a result of investing in derivatives, the Fund could lose more than the amount it invests. Derivatives may be highly illiquid, and the Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. Derivatives also may be subject to counterparty risk, which includes the risk that the Fund may sustain a loss as a result of the insolvency or bankruptcy of, or other non-compliance by, the other party to the transaction.

n  Calculation Methodology Risk — The Index relies on various sources of information to assess the criteria of issuers included in the Index, including information that may be based on assumptions and estimates. Neither the Fund, the Index Provider, nor the Adviser can offer assurances that the Index's calculation methodology or sources of information will provide an accurate assessment of included issuers or correct valuation of securities, nor can they guarantee the availability or timeliness of the production of an Index.

n  Passive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Performance

The bar chart and table that follow are intended to help you understand some of the risks of investing in the Fund. The bar chart shows you how the Fund's calendar year performance has varied over the past 10 years (or the life of the Fund if shorter). The table compares the Fund's average annual total returns over the same period to a broad measure of market performance. We assume reinvestment of dividends and distributions.

Performance information for the Fund prior to June 30, 2019 reflects the historical performance of the USAA MSCI USA Value Momentum Blend Index ETF, a series of USAA ETF Trust (the predecessor to the Fund managed by USAA Asset Management Company) (the "Predecessor Fund"). The Fund's performance has not been restated to reflect any differences in expenses paid by the Predecessor Fund and those paid by the Fund.

Updated performance information is available on the Fund's website at VictorySharesLiterature.com.

Calendar Year Returns

Highest Quarter  4.50% (quarter ended September 30, 2018)

Lowest Quarter  -15.37% (quarter ended December 31, 2018)

¹ Inception date is October 24, 2017.

After-tax returns use the historical highest individual federal marginal income tax rates and do not reflect the effect of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. After-tax returns shown are not relevant if you own your Fund Shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Investment Adviser

Victory Capital Management Inc. ("Adviser") serves as the Fund's investment adviser. The portfolio managers primarily responsible for day-to-day management of the Fund are members of the Adviser's Victory Solutions platform, which oversees the Adviser's rules-based investment strategies.

VictoryShares USAA MSCI USA Value Momentum ETF (continued)

Portfolio Managers

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only in large blocks of 50,000 Shares (each block of Shares is called a "Creation Unit"). Creation Units are issued and redeemed for cash and/or in-kind for securities by Authorized Participants ("APs") that have entered into agreements with the Fund's distributor. Individual Shares may only be purchased and sold through brokers in secondary market transactions on the NYSE Arca, Inc. (the "Exchange"). Except when aggregated in Creation Units, Shares are not redeemable securities of the Fund.

Shares of the Fund will be listed for trading on the Exchange and will trade at market prices rather than NAV. Shares of the Fund may trade at a price that is greater than (a premium), at, or less than (a discount) NAV.

Tax Information

The Fund's distributions generally will be taxable as ordinary income, qualified dividend income or capital gains. A sale of Shares may result in capital gain or loss.

Payment to Broker-Dealers and Other Financial Intermediaries

If you purchase Shares 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 Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

VictoryShares USAA MSCI USA Small Cap Value Momentum ETF

Investment Objective

The VictoryShares USAA MSCI USA Small Cap Value Momentum ETF (the "Fund") seeks to provide investment results that closely correspond, before fees and expenses, to the performance of the MSCI USA Small Cap Select Value Momentum Blend Index (the "Index").

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

¹"Other Expenses" reflect estimated expenses that the Fund expects to bear in the current fiscal year.

²Victory Capital Management Inc., the Fund's investment adviser, ("Adviser") has contractually agreed to waive its management fee and/or reimburse expenses through at least June 30, 2021 so that the total annual fund operating expenses after fee waiver and expense reimbursement (excluding certain items such as interest, taxes and brokerage commissions) do not exceed 0.25%. The Adviser is permitted to recoup advisory fees waived and expenses reimbursed by it or by the Fund's predecessor adviser for up to three years after the fiscal year in which the waiver or reimbursement took place, subject to the lesser of any operating expense limits in effect at the time of (a) the original waiver or expense reimbursement; or (b) the recoupment, after giving effect to the recoupment amount. This agreement may only be terminated by the Fund's Board of Trustees.

VictoryShares USAA MSCI USA Small Cap Value Momentum ETF (continued)

Fees and Expenses of the Fund (continued)

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, regardless whether or not you redeem your Shares at the end of such 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 upon these assumptions your costs would be:

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 will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. From commencement of operations, October 24, 2017, through the fiscal period ended August 31, 2018, the portfolio turnover rate of the Fund (when it was the Predecessor Fund, as defined below) was 81% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund seeks to achieve its investment objective by investing at least 80% of its assets in securities in the Index. MSCI, Inc. (the "Index Provider") constructs the Index in accordance with a rules-based methodology. The Index is comprised solely of securities issued by U.S. small capitalization companies.

The Index is designed to deliver exposure to equity securities of small-capitalization U.S. issuers within the MSCI USA Small Cap Index (the "Parent Index") that have higher exposure to value and momentum factors while also maintaining moderate Index turnover and lower realized volatility than traditional capitalization weighted indexes. The value factor indicates how attractively a stock is priced relative to its fundamentals, such as book value and free cash flow. A value score is derived from a company's valuation ratios, e.g. forward price to earnings, share price to book value, and enterprise value to operating cash flow. The momentum factor indicates whether changes in a company's share price are trending up or down. A momentum score is calculated using a security's price trends over the last six months and twelve months (except the previous month), adjusted for volatility. A security is only evaluated within a single industry or sector. A liquidity filter is applied to screen out securities with low liquidity. Securities generally are filtered by selecting the top 90% by count of securities in the Parent Index, based on the highest 12-month annualized traded value.

The Index Provider ranks each stock of the Parent Index based on its value and momentum scores, relative to their sector classification, and creates a composite score for each stock by equally weighting the stock's value and momentum score. The Index Provider then selects the top 25% of the ranked stocks of the Parent Index based on their composite scores for inclusion in the Index. The constituents are weighted such that securities with lower realized volatility are given higher Index weights. The Index rebalances quarterly. As of December 31, 2018, the market capitalization of the issuers in the Index ranged from $137.0 million to $9.0 billion. The range may change from time to time.

The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index. The Fund also may invest up to 20% of its assets in instruments other than the securities in the Index, which the Adviser believes will help the Fund track the Index. Such instruments may include derivatives, including index futures, which the Fund may use for cash management (attempting to remain fully invested while maintaining liquidity) or to gain exposure to an investment in a manner other than investing in the asset directly.

The Fund will concentrate its investments (i.e., hold more than 25% of its assets) in a particular industry or group of industries to the extent that its Index is concentrated. The degree to which certain sectors, industries, or asset classes are represented in the Index may change over time.

VictoryShares USAA MSCI USA Small Cap Value Momentum ETF (continued)

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

n  Market Risk — Any investment involves risk, and there is no assurance that the Fund's investment objective will be achieved. Losing money is a risk of investing in the Fund. The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments, and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets, or general investor sentiment. Individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

n  Index Risk — The Fund attempts to track the performance of a specific index. The Fund will be negatively affected by general declines in the securities and asset classes represented in the Index. In addition, because the Fund is not "actively" managed, unless a specific security is removed from the Index, the Fund generally would not sell a security because the security's issuer was in financial trouble. The Fund also does not attempt to take defensive positions under any market conditions, including declining markets. Therefore, the Fund's performance could be lower than funds that may actively shift their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline or a decline in the value of one or more issuers.

n  Tracking Error Risk — Tracking error is the divergence of the Fund's performance from that of the Index. The performance of the Fund may diverge from that of its Index for a number of reasons, such as the use of representative sampling (if applicable), transaction costs, the Fund's holding of cash, differences in accrual of dividends, changes to the Index, tax considerations, rebalancing, or new or existing regulatory requirements. Unlike the Fund, the returns of the Index are not reduced by investment and other operating expenses, including the trading costs associated with implementing changes to its portfolio of investments. Tracking error risk may be heightened during times of market volatility or other unusual market conditions. To the extent that the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities' closing prices (i.e., the value of the Index is not based on fair value prices), the Fund's ability to track the Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities to realize losses, which will result in a deviation from the Index.

n  Momentum Risk — Momentum investing entails investing more in securities that exhibit persistence in relative performance evidenced by better recent price performance compared to other securities. These securities may be more volatile than a broad cross-section of securities, and momentum may be an indicator that a security's price is peaking. Momentum can turn quickly and cause significant variation from other types of investments. The Fund may experience significant losses if momentum stops, turns or otherwise behaves differently than predicted.

n  Value Risk — Value investing entails investing in securities that are inexpensive relative to other securities based on ratios such as price to earnings or price to book. There may be periods when value investing is out of favor, and during which the investment performance of a fund using a value strategy may suffer. In addition, value stocks are subject to the risk that their intrinsic value may never be realized in the market.

n  Small-Capitalization Company Risk — Investments in small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, making it difficult for a Fund to buy and sell them at the time and price desired, and these issuers often face greater business risks. Small-capitalization companies typically are less financially stable than larger, more established companies, and may depend on a small number of key personnel, making them vulnerable to loss of personnel. These companies also generally have less diverse product lines than larger capitalization companies and are more susceptible to adverse developments related to their products.

VictoryShares USAA MSCI USA Small Cap Value Momentum ETF (continued)

n  Seed Investor or Large Shareholder Risk — Certain large shareholders, including other funds advised by the Adviser, may from time to time own a substantial amount of the Fund's Shares. In addition, seed investors, such as the Adviser, an affiliate of the Adviser, an Authorized Participant, a lead market maker, or other entity, may contribute all or a majority of the assets in the Fund to facilitate commencement of the Fund or to facilitate the Fund's achieving a specified size or scale. There is a risk that such large shareholders or seed investors may redeem their investments in the Fund, which could have a significant negative impact on the Fund's NAV, market price and brokerage costs.

n  Concentration Risk — In following its methodology, the Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Index concentrates in the securities of issuers in a particular industry or sector, the Fund also can be expected to concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund may face more risks than if it were diversified broadly over numerous industries or sectors. If the Index is not concentrated in a particular industry or sector, the Fund will not concentrate in a particular industry or sector.

n  Exchange-Traded Fund ("ETF") Structure Risk — The Fund is structured as an ETF and as a result is subject to special risks, including:

n  Not Individually Redeemable — The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

n  Trading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

n  Market Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly, particularly in times of market stress. This means that Shares may trade at a premium or discount to NAV.

n  Authorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

n  Intraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV"). The IIV is not a "real-time" update of the NAV per Share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

n  Liquidity Risk — The Fund is subject to liquidity risk, which is the risk that the Fund's investment may be difficult to purchase or sell and that an investment may not be sold or disposed of at an advantageous price or time.

VictoryShares USAA MSCI USA Small Cap Value Momentum ETF (continued)

n  Valuation Risk — The sale price the Fund could receive for a security may differ from the Fund's valuation of the security and may differ from the value used by the Index, particularly for securities that trade in low volume or volatile markets or that are valued using a fair value methodology. The Fund relies on various sources to calculate its NAV. The information may be provided by third parties that are believed to be reliable, but the information may not be accurate due to errors by such pricing sources, technological issues, or otherwise.

n  Derivatives Risk — Derivatives, including futures contracts, may involve risks different from, or greater than, those associated with more traditional investments. In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage, and liquidity risks. Derivatives may create leverage and expose the Fund to additional levels of risk, including greater losses from investments and increased volatility, than would otherwise have been the case had the Fund not engaged in the activities that created the leverage. As a result of investing in derivatives, the Fund could lose more than the amount it invests. Derivatives may be highly illiquid, and the Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. Derivatives also may be subject to counterparty risk, which includes the risk that the Fund may sustain a loss as a result of the insolvency or bankruptcy of, or other non-compliance by, the other party to the transaction.

n  Calculation Methodology Risk — The Index relies on various sources of information to assess the criteria of issuers included in the Index, including information that may be based on assumptions and estimates. Neither the Fund, the Index Provider, nor the Adviser can offer assurances that the Index's calculation methodology or sources of information will provide an accurate assessment of included issuers or correct valuation of securities, nor can they guarantee the availability or timeliness of the production of an Index.

n  Passive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

Investment Objective

The VictoryShares USAA MSCI International Value Momentum ETF (the "Fund") seeks to provide investment results that closely correspond, before fees and expenses, to the performance of the MSCI World ex USA Select Value Momentum Blend Index (the "Index").

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

¹"Other Expenses" reflect estimated expenses that the Fund expects to bear in the current fiscal year.

²Victory Capital Management Inc., the Fund's investment adviser, ("Adviser") has contractually agreed to waive its management fee and/or reimburse expenses through at least June 30, 2021 so that the total annual fund operating expenses after fee waiver and expense reimbursement (excluding certain items such as interest, taxes and brokerage commissions) do not exceed 0.35%. The Adviser is permitted to recoup advisory fees waived and expenses reimbursed by it or by the Fund's predecessor adviser for up to three years after the fiscal year in which the waiver or reimbursement took place, subject to the lesser of any operating expense limits in effect at the time of (a) the original waiver or expense reimbursement; or (b) the recoupment, after giving effect to the recoupment amount. This agreement may only be terminated by the Fund's Board of Trustees.

Fees and Expenses of the Fund (continued)

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, regardless whether or not you redeem your Shares at the end of such periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

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 will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. From commencement of operations, October 24, 2017, through the fiscal period ended August 31, 2018, the portfolio turnover rate of the Fund (when it was the Predecessor Fund, as defined below) was 65% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund seeks to achieve its investment objective by investing at least 80% of its assets in securities in the Index, depositary receipts on securities in the Index, and securities underlying depositary receipts in the Index. MSCI, Inc. (the "Index Provider") constructs the Index in accordance with a rules-based methodology.

The Index is designed to deliver exposure to equity market performance in non-U.S. developed markets and provide higher exposure to value and momentum factors within the MSCI World ex USA Index (the "Parent Index") while also maintaining moderate Index turnover and lower realized volatility than traditional capitalization weighted indexes. The value factor indicates how attractively a stock is priced relative to its fundamentals, such as book value and free cash flow. A value score is derived from a company's valuation ratios, e.g. forward price to earnings, share price to book value, and enterprise value to operating cash flow. The momentum factor indicates whether changes in a company's share price are trending up or down. A momentum score is calculated using a security's price trends over the last six months and twelve months (except the previous month), adjusted for volatility. A security is only evaluated within a single industry or sector.

The Index Provider ranks each component of the Parent Index based on its value and momentum scores, relative to their sector classification, and creates a composite score for each stock by equally weighting the stock's value and momentum score. The Index Provider then selects the top 25% of the ranked stocks of the Parent Index based on their composite scores for inclusion in the Index. The constituents are weighted such that securities with lower realized volatility are given higher Index weights. The Index rebalances quarterly. In order to limit over weighting, the Index has a defined a threshold of 5% relative to the Parent Index in geographic regions, as defined by the Index Provider. As of December 31, 2018, the Index provided exposure to the following countries: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, and the United Kingdom.

The Index is comprised of equity securities, including American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs").

The Fund seeks to track the returns of the Index before fees and expenses by employing, under normal circumstances, a "sampling" process to invest in a representative sample of stocks included in the Index. The Fund's portfolio managers select these stocks using a statistical optimization process designed to produce investment characteristics that closely approximate those of the Index.

VictoryShares USAA MSCI International Value Momentum ETF (continued)

The Fund also may invest up to 20% of its assets in instruments other than the securities in the Index, which the Adviser believes will help the Fund track the Index. Such instruments may include derivatives, including index futures, which the Fund may use for cash management (attempting to remain fully invested while maintaining liquidity) or to gain exposure to an investment in a manner other than investing in the asset directly.

The Fund will concentrate its investments (i.e., hold more than 25% of its assets) in a particular industry or group of industries to the extent that its Index is concentrated. The degree to which certain sectors, industries, or asset classes are represented in the Index may change over time.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

n  Market Risk — Any investment involves risk, and there is no assurance that the Fund's investment objective will be achieved. Losing money is a risk of investing in the Fund. The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments, and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets, or general investor sentiment. Individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

n    Index Risk — The Fund attempts to track the performance of a specific index. The Fund will be negatively affected by general declines in the securities and asset classes represented in the Index. In addition, because the Fund is not "actively" managed, unless a specific security is removed from the Index, the Fund generally would not sell a security because the security's issuer was in financial trouble. The Fund also does not attempt to take defensive positions under any market conditions, including declining markets. Therefore, the Fund's performance could be lower than funds that may actively shift their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline or a decline in the value of one or more issuers.

n  Tracking Error Risk — Tracking error is the divergence of the Fund's performance from that of the Index. The performance of the Fund may diverge from that of its Index for a number of reasons, such as the use of representative sampling (if applicable), transaction costs, the Fund's holding of cash, differences in accrual of dividends, changes to the Index, tax considerations, rebalancing, or new or existing regulatory requirements. Unlike the Fund, the returns of the Index are not reduced by investment and other operating expenses, including the trading costs associated with implementing changes to its portfolio of investments. Tracking error risk may be heightened during times of market volatility or other unusual market conditions. To the extent that the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities' closing prices (i.e., the value of the Index is not based on fair value prices), the Fund's ability to track the Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities to realize losses, which will result in a deviation from the Index.

n  Sampling Risk — The Fund's use of a representative sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer or a small number of issuers of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

n  Momentum Risk — Momentum investing entails investing more in securities that exhibit persistence in relative performance evidenced by better recent price performance compared to other securities. These securities may be more volatile than a broad cross-section of securities, and momentum may be an indicator that a security's price is peaking. Momentum can turn quickly and cause significant variation from other types of investments. The Fund may experience significant losses if momentum stops, turns or otherwise behaves differently than predicted.

n  Value Risk — Value investing entails investing in securities that are inexpensive relative to other securities based on ratios such as price to earnings or price to book. There may be periods when value

VictoryShares USAA MSCI International Value Momentum ETF (continued)

investing is out of favor, and during which the investment performance of a fund using a value strategy may suffer. In addition, value stocks are subject to the risk that their intrinsic value may never be realized in the market.

n  Foreign Securities Risk — Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information, and less economic, political, and social stability in the countries in which the Fund invests. The imposition of exchange controls, sanctions, confiscations, trade restrictions (including tariffs), and other government restrictions by the United States or other governments; or problems in share registration, settlement, or custody also may result in losses. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time.

n  Geographic Risk — To the extent the Index focuses its investments in issuers located in a particular country or region, the Fund is subject to greater risks of volatile economic cycles and/or conditions and developments that may be particular to that country or region. For example, the Fund may be subject to greater risk of adverse securities markets, exchange rates, social, political, regulatory, economic, business, environmental or other developments, or natural disasters.

n  Currency Risk — Investments in foreign currencies and in securities that trade in, or receive revenues in, or in derivatives that provide exposure to foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar. Any such decline may erode or reverse any potential gains from an investment in securities denominated in foreign currency or may widen existing loss. Currency rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates; intervention (or the failure to intervene) by governments, central banks or supranational entities; the imposition of currency controls; or other political developments in the United States or abroad.

n  Depositary Receipts Risk — Foreign securities may trade in the form of depositary receipts, which include ADRs and GDRs (collectively "Depositary Receipts"). To the extent the Fund acquires Depositary Receipts through banks which do not have a contractual relationship with the foreign issuer of the security underlying the Depositary Receipts to issue and service such unsponsored Depositary Receipts, the Fund may not be aware of and be able to respond to corporate actions such as stock splits or rights offerings involving the foreign issuer in a timely manner. In addition, the lack of information may result in inefficiencies in the valuation of such instruments. Investment in Depositary Receipts does not eliminate all the risks inherent in investing in securities of non-U.S. issuers. The market value of Depositary Receipts depends on the market value of the underlying securities and fluctuations in the relative value of the currencies in which the Depositary Receipts and the underlying securities are quoted.

n  Investments in Depositary Receipts may be less liquid and more volatile than the underlying securities in their primary trading market.

n  If a Depositary Receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the Depositary Receipt and the underlying security.

n  Holders of Depositary Receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action.

n  The prices of Depositary Receipts may differ from the prices of securities upon which they are based.

n  To the extent the Fund invests in Depositary Receipts based on securities included in the Index, such differences in prices may increase index tracking risk.

n  Mid-Capitalization and Small-Capitalization Company Risk — Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

n  Large-Capitalization Company Risk — Investments in large-capitalization companies may go in and out of favor based on market and economic conditions and may underperform other market segments.

VictoryShares USAA MSCI International Value Momentum ETF (continued)

Some large-capitalization companies may be unable to respond quickly to new competitive challenges and attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion. As such, returns on investments in stocks of large-capitalization companies could trail the returns on investments in stocks of small- and mid-capitalization companies.

n  Seed Investor or Large Shareholder Risk — Certain large shareholders, including other funds advised by the Adviser, may from time to time own a substantial amount of the Fund's Shares. In addition, seed investors, such as the Adviser, an affiliate of the Adviser, an Authorized Participant, a lead market maker, or other entity, may contribute all or a majority of the assets in the Fund to facilitate commencement of the Fund or to facilitate the Fund's achieving a specified size or scale. There is a risk that such large shareholders or seed investors may redeem their investments in the Fund, which could have a significant negative impact on the Fund's NAV, market price and brokerage costs.

n  Concentration Risk — In following its methodology, the Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Index concentrates in the securities of issuers in a particular industry or sector, the Fund also can be expected to concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund may face more risks than if it were diversified broadly over numerous industries or sectors. If the Index is not concentrated in a particular industry or sector, the Fund will not concentrate in a particular industry or sector.

n  Exchange-Traded Fund ("ETF") Structure Risk — The Fund is structured as an ETF and as a result is subject to special risks, including:

n    Not Individually Redeemable — The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

n  Trading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

n  Market Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly, particularly in times of market stress. This means that Shares may trade at a premium or discount to NAV.

n  Authorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

n  Intraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV"). The IIV is not a "real-time" update of the NAV per Share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

n  Liquidity Risk — The Fund is subject to liquidity risk, which is the risk that the Fund's investment may be difficult to purchase or sell and that an investment may not be sold or disposed of at an advantageous price or time.

VictoryShares USAA MSCI International Value Momentum ETF (continued)

n  Valuation Risk — The sale price the Fund could receive for a security may differ from the Fund's valuation of the security and may differ from the value used by the Index, particularly for securities that trade in low volume or volatile markets or that are valued using a fair value methodology. The Fund relies on various sources to calculate its NAV. The information may be provided by third parties that are believed to be reliable, but the information may not be accurate due to errors by such pricing sources, technological issues, or otherwise.

n  Derivatives Risk — Derivatives, including futures contracts, may involve risks different from, or greater than, those associated with more traditional investments. In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage, and liquidity risks. Derivatives may create leverage and expose the Fund to additional levels of risk, including greater losses from investments and increased volatility, than would otherwise have been the case had the Fund not engaged in the activities that created the leverage. As a result of investing in derivatives, the Fund could lose more than the amount it invests. Derivatives may be highly illiquid, and the Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. Derivatives also may be subject to counterparty risk, which includes the risk that the Fund may sustain a loss as a result of the insolvency or bankruptcy of, or other non-compliance by, the other party to the transaction.

n  Calculation Methodology Risk — The Index relies on various sources of information to assess the criteria of issuers included in the Index, including information that may be based on assumptions and estimates. Neither the Fund, the Index Provider, nor the Adviser can offer assurances that the Index's calculation methodology or sources of information will provide an accurate assessment of included issuers or correct valuation of securities, nor can they guarantee the availability or timeliness of the production of an Index.

n  Passive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Performance

The bar chart and table that follow are intended to help you understand some of the risks of investing in the Fund. The bar chart shows you how the Fund's calendar year performance has varied over the past 10 years (or the life of the Fund if shorter). The table compares the Fund's average annual total returns over the same period to a broad measure of market performance. We assume reinvestment of dividends and distributions.

Performance information for the Fund prior to June 30, 2019 reflects the historical performance of the USAA MSCI International Value Momentum Blend Index ETF, a series of USAA ETF Trust (the predecessor to the Fund managed by USAA Asset Management Company) (the "Predecessor Fund"). The Fund's performance has not been restated to reflect any differences in expenses paid by the Predecessor Fund and those paid by the Fund.

Updated performance information is available on the Fund's website at VictorySharesLiterature.com.

Calendar Year Returns

Highest Quarter  1.08% (quarter ended September 30, 2018)

Lowest Quarter  -14.05% (quarter ended December 31, 2018)

¹ Inception date is October 24, 2017.

After-tax returns use the historical highest individual federal marginal income tax rates and do not reflect the effect of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. After-tax returns shown are not relevant if you own your Fund Shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Investment Adviser

Victory Capital Management Inc. ("Adviser") serves as the Fund's investment adviser. The portfolio managers primarily responsible for day-to-day management of the Fund are members of the Adviser's Victory Solutions platform, which oversees the Adviser's rules-based investment strategies.

Portfolio Managers

VictoryShares USAA MSCI International Value Momentum ETF (continued)

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only in large blocks of 50,000 Shares (each block of Shares is called a "Creation Unit"). Creation Units are issued and redeemed for cash and/or in-kind for securities by Authorized Participants ("APs") that have entered into agreements with the Fund's distributor. Individual Shares may only be purchased and sold through brokers in secondary market transactions on the NYSE Arca, Inc. (the "Exchange"). Except when aggregated in Creation Units, Shares are not redeemable securities of the Fund.

Shares of the Fund will be listed for trading on the Exchange and will trade at market prices rather than NAV. Shares of the Fund may trade at a price that is greater than (a premium), at, or less than (a discount) NAV.

Tax Information

The Fund's distributions generally will be taxable as ordinary income, qualified dividend income or capital gains. A sale of Shares may result in capital gain or loss.

Payment to Broker-Dealers and Other Financial Intermediaries

If you purchase Shares 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 Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

Investment Objective

The VictoryShares USAA MSCI Emerging Markets Value Momentum ETF (the "Fund") seeks to provide investment results that closely correspond, before fees and expenses, to the performance of the MSCI Emerging Markets Select Value Momentum Blend Index (the "Index").

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

¹"Other Expenses" reflect estimated expenses that the Fund expects to bear in the current fiscal year.

²Victory Capital Management Inc., the Fund's investment adviser, ("Adviser") has contractually agreed to waive its management fee and/or reimburse expenses through at least June 30, 2021 so that the total annual fund operating expenses after fee waiver and expense reimbursement (excluding certain items such as interest, taxes and brokerage commissions) do not exceed 0.45%. The Adviser is permitted to recoup advisory fees waived and expenses reimbursed by it or by the Fund's predecessor adviser for up to three years after the fiscal year in which the waiver or reimbursement took place, subject to the lesser of any operating expense limits in effect at the time of (a) the original waiver or expense reimbursement; or (b) the recoupment, after giving effect to the recoupment amount. This agreement may only be terminated by the Fund's Board of Trustees.

VictoryShares USAA MSCI Emerging Markets Value Momentum ETF (continued)

Fees and Expenses of the Fund (continued)

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, regardless whether or not you redeem your Shares at the end of such periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

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 will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. From commencement of operations, October 24, 2017, through the fiscal period ended August 31, 2018, the portfolio turnover rate of the Fund (when it was the Predecessor Fund, as defined below) was 58% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund seeks to achieve its investment objective by investing at least 80% of its assets in securities in the Index, depositary receipts on securities in the Index, and securities underlying depositary receipts in the Index. MSCI, Inc. (the "Index Provider") constructs the Index in accordance with a rules-based methodology. The Index is comprised solely of securities issued by companies associated with emerging market countries as described more fully below.

The Index is designed to deliver exposure to equity market performance in the global emerging markets and provide higher exposure to value and momentum factors within the MSCI Emerging Markets Index (the "Parent Index") while also maintaining moderate Index turnover and lower realized volatility than traditional capitalization weighted indexes. A liquidity filter is applied to screen out securities with low liquidity. Securities generally are filtered by selecting the top 90% by count of securities in the Parent Index, based on the highest 12-month annualized traded value. The Index Provider determines whether an issuer is located in a particular country by reference to the Index methodology.

The value factor indicates how attractively a stock is priced relative to its fundamentals, such as book value and free cash flow. A value score is derived from a company's valuation ratios, e.g. forward price to earnings, share price to book value, and enterprise value to operating cash flow. The momentum factor indicates whether changes in a company's share price are trending up or down. A momentum score is calculated using a security's price trends over the last six months and twelve months (except the previous month), adjusted for volatility. A security is only evaluated within a single industry or sector.

The Index Provider ranks each stock of the Parent Index based on its value and momentum scores, relative to their sector classification, and creates a composite score for each stock by equally weighting the stock's value and momentum score. The Index Provider then selects the top 25% of the ranked stocks of the Parent Index based on their composite scores for inclusion in the Index. The constituents are weighted such that securities with lower realized volatility are given higher Index weights. In order to limit over weighting, the Index has a defined a threshold of 5% relative to the Parent Index in geographic regions, as defined by the Index Provider.

The Index is comprised of equity securities, including American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs").

As of December 31, 2018, the emerging market countries include: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Korea, Malaysia, Mexico, Poland, Qatar, Russia, South Africa, Taiwan, Thailand, and Turkey.

VictoryShares USAA MSCI Emerging Markets Value Momentum ETF (continued)

The Fund seeks to track the returns of the Index before fees and expenses by employing, under normal circumstances, a "sampling" process to invest in a representative sample of stocks included in the Index. The Fund's portfolio managers select these stocks using a statistical optimization process designed to produce investment characteristics that closely approximate those of the Index.

The Fund also may invest up to 20% of its assets in instruments other than the securities in the Index, which the Adviser believes will help the Fund track the Index. Such instruments may include derivatives, including index futures, which the Fund may use for cash management (attempting to remain fully invested while maintaining liquidity) or to gain exposure to an investment in a manner other than investing in the asset directly.

The Fund will concentrate its investments (i.e., hold more than 25% of its assets) in a particular industry or group of industries to the extent that its Index is concentrated. The degree to which certain sectors, industries, or asset classes are represented in the Index may change over time. The Index will rebalance quarterly.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

n  Market Risk — Any investment involves risk, and there is no assurance that the Fund's investment objective will be achieved. Losing money is a risk of investing in the Fund. The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments, and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets, or general investor sentiment. Individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

n  Index Risk — The Fund attempts to track the performance of a specific index. The Fund will be negatively affected by general declines in the securities and asset classes represented in the Index. In addition, because the Fund is not "actively" managed, unless a specific security is removed from the Index, the Fund generally would not sell a security because the security's issuer was in financial trouble. The Fund also does not attempt to take defensive positions under any market conditions, including declining markets. Therefore, the Fund's performance could be lower than funds that may actively shift their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline or a decline in the value of one or more issuers.

n  Tracking Error Risk — Tracking error is the divergence of the Fund's performance from that of the Index. The performance of the Fund may diverge from that of its Index for a number of reasons, such as the use of representative sampling (if applicable), transaction costs, the Fund's holding of cash, differences in accrual of dividends, changes to the Index, tax considerations, rebalancing, or new or existing regulatory requirements. Unlike the Fund, the returns of the Index are not reduced by investment and other operating expenses, including the trading costs associated with implementing changes to its portfolio of investments. Tracking error risk may be heightened during times of market volatility or other unusual market conditions. To the extent that the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities' closing prices (i.e., the value of the Index is not based on fair value prices), the Fund's ability to track the Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities to realize losses, which will result in a deviation from the Index.

n  Sampling Risk — The Fund's use of a representative sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer or a small number of issuers of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

n  Momentum Risk — Momentum investing entails investing more in securities that exhibit persistence in relative performance evidenced by better recent price performance compared to other securities. These securities may be more volatile than a broad cross-section of securities, and momentum may be

VictoryShares USAA MSCI Emerging Markets Value Momentum ETF (continued)

an indicator that a security's price is peaking. Momentum can turn quickly and cause significant variation from other types of investments. The Fund may experience significant losses if momentum stops, turns or otherwise behaves differently than predicted.

n  Value Risk — Value investing entails investing in securities that are inexpensive relative to other securities based on ratios such as price to earnings or price to book. There may be periods when value investing is out of favor, and during which the investment performance of a fund using a value strategy may suffer. In addition, value stocks are subject to the risk that their intrinsic value may never be realized in the market.

n  Foreign Securities and Emerging Countries Risk — Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information, and less economic, political, and social stability in the countries in which the Fund invests. The imposition of exchange controls, sanctions, confiscations, trade restrictions (including tariffs), and other government restrictions by the United States or other governments; or problems in share registration, settlement, or custody also may result in losses. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. These risks may be more pronounced in connection with the Fund's investments in securities of issuers located in emerging countries. The securities markets of most emerging countries are less liquid, developed, and efficient; are subject to greater price volatility; have smaller market capitalizations; have more or less government regulation; and may not be subject to as extensive and frequent accounting, financial and other reporting requirements as the securities markets of more developed countries. Further, investment in securities of issuers located in certain emerging countries involves the risk of loss resulting from problems in share registration, settlement, or custody and substantial economic, political, and social disruptions. These risks are not normally associated with investments in more developed countries.

n  Geographic Risk — To the extent the Index focuses its investments in issuers located in a particular country or region, the Fund is subject to greater risks of volatile economic cycles and/or conditions and developments that may be particular to that country or region. For example, the Fund may be subject to greater risk of adverse securities markets, exchange rates, social, political, regulatory, economic, business, environmental or other developments, or natural disasters.

n  Currency Risk — Investments in foreign currencies and in securities that trade in, or receive revenues in, or in derivatives that provide exposure to foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar. Any such decline may erode or reverse any potential gains from an investment in securities denominated in foreign currency or may widen existing loss. Currency rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates; intervention (or the failure to intervene) by governments, central banks or supranational entities; the imposition of currency controls; or other political developments in the United States or abroad.

n  Depositary Receipts Risk — Foreign securities may trade in the form of depositary receipts, which include ADRs and GDRs (collectively "Depositary Receipts"). To the extent the Fund acquires Depositary Receipts through banks which do not have a contractual relationship with the foreign issuer of the security underlying the Depositary Receipts to issue and service such unsponsored Depositary Receipts, the Fund may not be aware of and be able to respond to corporate actions such as stock splits or rights offerings involving the foreign issuer in a timely manner. In addition, the lack of information may result in inefficiencies in the valuation of such instruments. Investment in Depositary Receipts does not eliminate all the risks inherent in investing in securities of non-U.S. issuers. The market value of Depositary Receipts depends on the market value of the underlying securities and fluctuations in the relative value of the currencies in which the Depositary Receipts and the underlying securities are quoted.

n  Investments in Depositary Receipts may be less liquid and more volatile than the underlying securities in their primary trading market.

VictoryShares USAA MSCI Emerging Markets Value Momentum ETF (continued)

n    If a Depositary Receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the Depositary Receipt and the underlying security.

n  Holders of Depositary Receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action.

n  The prices of Depositary Receipts may differ from the prices of securities upon which they are based.

n  To the extent the Fund invests in Depositary Receipts based on securities included in the Index, such differences in prices may increase index tracking risk.

n  Mid-Capitalization and Small-Capitalization Company Risk — Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

n  Seed Investor or Large Shareholder Risk — Certain large shareholders, including other funds advised by the Adviser, may from time to time own a substantial amount of the Fund's Shares. In addition, seed investors, such as the Adviser, an affiliate of the Adviser, an Authorized Participant, a lead market maker, or other entity, may contribute all or a majority of the assets in the Fund to facilitate commencement of the Fund or to facilitate the Fund's achieving a specified size or scale. There is a risk that such large shareholders or seed investors may redeem their investments in the Fund, which could have a significant negative impact on the Fund's NAV, market price and brokerage costs.

n  Concentration Risk — In following its methodology, the Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Index concentrates in the securities of issuers in a particular industry or sector, the Fund also can be expected to concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund may face more risks than if it were diversified broadly over numerous industries or sectors. If the Index is not concentrated in a particular industry or sector, the Fund will not concentrate in a particular industry or sector.

n  Exchange-Traded Fund ("ETF") Structure Risk — The Fund is structured as an ETF and as a result is subject to special risks, including:

n  Not Individually Redeemable — The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

n  Trading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

n  Market Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly, particularly in times of market stress. This means that Shares may trade at a premium or discount to NAV.

n  Authorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

n  Intraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the

VictoryShares USAA MSCI Emerging Markets Value Momentum ETF (continued)

"intraday indicative value" or "IIV"). The IIV is not a "real-time" update of the NAV per Share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

n  Liquidity Risk — The Fund is subject to liquidity risk, which is the risk that the Fund's investment may be difficult to purchase or sell and that an investment may not be sold or disposed of at an advantageous price or time.

n  Valuation Risk — The sale price the Fund could receive for a security may differ from the Fund's valuation of the security and may differ from the value used by the Index, particularly for securities that trade in low volume or volatile markets or that are valued using a fair value methodology. The Fund relies on various sources to calculate its NAV. The information may be provided by third parties that are believed to be reliable, but the information may not be accurate due to errors by such pricing sources, technological issues, or otherwise.

n  Derivatives Risk — Derivatives, including futures contracts, may involve risks different from, or greater than, those associated with more traditional investments. In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage, and liquidity risks. Derivatives may create leverage and expose the Fund to additional levels of risk, including greater losses from investments and increased volatility, than would otherwise have been the case had the Fund not engaged in the activities that created the leverage. As a result of investing in derivatives, the Fund could lose more than the amount it invests. Derivatives may be highly illiquid, and the Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. Derivatives also may be subject to counterparty risk, which includes the risk that the Fund may sustain a loss as a result of the insolvency or bankruptcy of, or other non-compliance by, the other party to the transaction.

n  Calculation Methodology Risk — The Index relies on various sources of information to assess the criteria of issuers included in the Index, including information that may be based on assumptions and estimates. Neither the Fund, the Index Provider, nor the Adviser can offer assurancesthat the Index's calculation methodology or sources of information will provide an accurate assessment of included issuers or correct valuation of securities, nor can they guarantee the availability or timeliness of the production of an Index.

n  Passive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Performance

The bar chart and table that follow are intended to help you understand some of the risks of investing in the Fund. The bar chart shows you how the Fund's calendar year performance has varied over the past 10 years (or the life of the Fund if shorter). The table compares the Fund's average annual total returns over the same period to a broad measure of market performance. We assume reinvestment of dividends and distributions.

Performance information for the Fund prior to June 30, 2019 reflects the historical performance of the USAA MSCI Emerging Markets Value Momentum Blend Index ETF, a series of USAA ETF Trust (the predecessor to the Fund managed by USAA Asset Management Company) (the "Predecessor Fund"). The Fund's performance has not been restated to reflect any differences in expenses paid by the Predecessor Fund and those paid by the Fund.

Updated performance information is available on the Fund's website at VictorySharesLiterature.com.

Calendar Year Returns

Highest Quarter  1.36% (quarter ended March 31, 2018)

Lowest Quarter  -7.74% (quarter ended December 31, 2018)

¹ Inception date is October 24, 2017.

After-tax returns use the historical highest individual federal marginal income tax rates and do not reflect the effect of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. After-tax returns shown are not relevant if you own your Fund Shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Investment Adviser

Victory Capital Management Inc. ("Adviser") serves as the Fund's investment adviser. The portfolio managers primarily responsible for day-to-day management of the Fund are members of the Adviser's Victory Solutions platform, which oversees the Adviser's rules-based investment strategies.

Portfolio Managers

VictoryShares USAA MSCI Emerging Markets Value Momentum ETF (continued)

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only in large blocks of 50,000 Shares (each block of Shares is called a "Creation Unit"). Creation Units are issued and redeemed for cash and/or in-kind for securities by Authorized Participants ("APs") that have entered into agreements with the Fund's distributor. Individual Shares may only be purchased and sold through brokers in secondary market transactions on the NYSE Arca, Inc. (the "Exchange"). Except when aggregated in Creation Units, Shares are not redeemable securities of the Fund.

Shares of the Fund will be listed for trading on the Exchange and will trade at market prices rather than NAV. Shares of the Fund may trade at a price that is greater than (a premium), at, or less than (a discount) NAV.

Tax Information

The Fund's distributions generally will be taxable as ordinary income, qualified dividend income or capital gains. A sale of Shares may result in capital gain or loss.

Payment to Broker-Dealers and Other Financial Intermediaries

If you purchase Shares 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 Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

Additional Fund Information

Investments

The VictoryShares USAA MSCI USA Value Momentum ETF ("US Fund"), VictoryShares USAA MSCI USA Small Cap Value Momentum ETF ("US Small Cap Fund"), VictoryShares USAA MSCI International Value Momentum ETF ("International Fund") and VictoryShares USAA MSCI Emerging Markets Value Momentum ETF ("Emerging Markets Fund") are each organized as an exchange-traded fund ("ETF"), each having distinct investment management objectives, strategies, risks, and policies. Together, these funds are sometimes referred to in this Prospectus as the "VictoryShares ETFs," "Victory Funds", or, more simply, the "Funds."

The International Fund and Emerging Markets Fund are collectively referred to in this Prospectus as the "International Funds."

The following describes additional information about the principal investment strategies that the Funds will use under normal market conditions to pursue their investment objectives, as well as any secondary strategies the Funds may use, and the related risks. This Prospectus does not attempt to describe all of the various investment techniques and types of investments that the Adviser may use in managing the Funds. The SAI includes more information about the Funds, their investments, and the related risks.

Information about each Fund's principal investment strategies is provided in the relevant summary section for each Fund. Below is additional information, describing in greater detail the principal investment strategies, including the practices and methodologies that the Adviser utilizes in pursuing a Fund's investment objective and principal investment strategies, as well as each Fund's principal investment risks.

In managing the Funds, the Adviser uses a "passive" or indexing approach to try to achieve the Fund's investment objective. Under normal market conditions, each Fund pursues its investment objective by seeking to track the price and yield performance, before fees and expenses, of a particular index maintained by the Index Provider (each an "Index"). The Funds do not try to outperform their indexes.

The Adviser expects that, over time, the correlation between a Fund's performance and that of the Index, before fees and expenses, will be 95% or better. A number of factors may affect the Fund's ability to achieve a high degree of correlation with its Index, and there can be no guarantee that a Fund will achieve a high degree of correlation. The Adviser monitors each Fund on an ongoing basis, and makes adjustments to its portfolio, as necessary, to minimize tracking error and to maintain liquidity.

For cash management purposes, each Fund is permitted to hold all or a portion of its assets in cash, index futures, short-term money market instruments or shares of other investment companies, including money market funds. To the extent that it does so, the Fund may not benefit from any upswing in the market and may fail to meet its investment objective.

Each Fund's investment objective and policy to invest at least 80% of its assets in the securities of its respective Index are non-fundamental and may be changed by the Board of Trustees upon at least 60 days' written notice to shareholders. For purposes of a Fund's 80% investment policy, "assets" means the Fund's net assets plus the amount of any borrowings for investment purposes, exclusive of collateral held from securities lending. Any derivatives counted towards the Fund's 80% policy will be valued at market value.

The Index Provider for the Indexes underlying the International Funds determines whether an issuer is located in a particular country by reference to the Index methodology. In general, the Index Provider determines the country classification of a company by the company's country of incorporation and the primary listing of its securities. If these countries are different, the Index Provider performs additional analysis to determine the company's

Additional Fund Information (continued)

country classification. The Index Provider considers a set of criteria, including: (1) the security's secondary listings if any; (2) the geographic distribution of the company's shareholder base; (3) the location of its headquarters; (4) the geographic distribution of its operations (in terms of assets and revenues); (5) the company's history, and (6) the country in which investors consider the company to be most appropriately classified.

The Adviser may use several types of investments and investment techniques in pursuing the Funds' overall investment objective. The following describes the types of securities the Adviser may purchase or the investment techniques the Adviser may employ but which the Adviser does not consider to be a part of a Fund's principal investment strategies. Additional types of securities and strategies that the Funds may utilize are included in the Funds' Statement of Additional Information ("SAI").

Securities Lending

To enhance the return on its portfolio, the Fund may lend portfolio securities to brokers, dealers and financial institutions to realize additional income under guidelines adopted by the Board. Each loan will be secured continuously by collateral in the form of cash, high quality money market instruments or securities issued by the U.S. government or its agencies or instrumentalities.

Investment Companies

A Fund may invest in securities of other investment companies, including ETFs, if those companies invest in securities consistent with the Fund's investment objective and policies. ETFs are investment companies, the shares of which are bought and sold on a securities exchange.

Risk Factors

The following describes the principal risks that you may assume as an investor in a Fund. These risks could adversely affect the net asset value, total return and the value of a Fund and your investment. The risk descriptions below provide a more detailed explanation of the principal investment risks that correspond to the risks described in each Fund's Fund Summary section of its Prospectus.

There is no assurance that a Fund will achieve its investment objective. Each Fund's Share price will fluctuate with changes in the market value of its portfolio investments. When you sell your Fund Shares, they may be worth less than what you paid for them and, accordingly, you can lose money investing in the Funds. No Fund, by itself, is intended to be a complete investment program.

n  Calculation Methodology Risk — An Index relies on various sources of information to assess the criteria of issuers included in the Index, including information that may be based on assumptions and estimates. Neither a Fund, the Index Provider, nor the Adviser can offer assurances that an Index's calculation methodology or sources of information will provide an accurate assessment of included issuers or correct valuation of securities, nor can they guarantee the availability or timeliness of the production of an Index. An Index has a limited performance history.

n  Concentration Risk — In following its methodology, an Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that an Index concentrates in the securities of issuers in a particular industry or sector, a Fund also can be expected to concentrate its investments to approximately

Risk Factors (continued)

the same extent. By concentrating its investments in an industry or sector, a Fund may face more risks than if it were diversified broadly over numerous industries or sectors. If an Index is not concentrated in a particular industry or sector, a Fund will not concentrate in a particular industry or sector.

n  Derivatives Risk — Derivatives, such as futures contracts, are subject to the risk that small price movements can result in substantial gains or losses. Derivatives also entail exposure to counterparty risk, the risk of mispricing or improper valuation and the risk that changes in value of the derivative may not correlate perfectly with the relevant securities, assets or indices. The Fund "covers" its exposure to certain derivative contracts by segregating or designating liquid assets on its records sufficient to satisfy current payment obligations, which may expose the Fund to the market through both the underlying assets subject to the contract and the assets used as cover. The use of derivatives could expose a Fund to the effects of leverage causing the Fund to lose more money than it invested. There is no guarantee that derivatives activities will be employed or that they will work, and their use could lower returns or even result in losses to the Fund. Derivatives also may be harder to value, less tax-efficient, and subject to changing government regulation that could impact the Fund's ability to use certain derivatives or their cost.

n  Emerging-Markets Risk — Investments in countries that are in the early stages of their industrial development involve exposure to economic structures that generally are less economically diverse and mature than those in the United States, and to political systems that may be less stable. Investments in emerging markets may be subject to the risk of abrupt and severe price declines and their financial markets often lack liquidity. In addition, emerging-market countries may be more likely than developed countries to experience rapid and significant adverse developments in their political or economic structures. Emerging-market economies also may be overly reliant on particular industries, and more vulnerable to shifts in international trade, trade barriers, and other protectionist or retaliatory measures. Governments in many emerging-market countries participate to a significant degree in their economies and securities markets. Some emerging-market countries restrict foreign investments, impose high withholding or other taxes on foreign investments, impose restrictive exchange control regulations, or may nationalize or expropriate the assets of private companies. Emerging-market countries also may be subject to high inflation and rapid currency devaluations and currency-hedging techniques may be unavailable in certain emerging-market countries.

n  Exchange-Traded Fund ("ETF") Structure Risk — Each Fund is structured as an ETF and as a result is subject to special risks, including:

n  Not Individually Redeemable — Shares are not individually redeemable and may be redeemed by a Fund at NAV only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

n  Trading Issues — Although the Shares are listed on the Exchange, there can be no assurance that an active, liquid or otherwise orderly trading market for Shares will be established or maintained by market makers or Authorized Participants, particularly in times of stressed market conditions. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions,

Risk Factors (continued)

the market for Shares may become less liquid in response to deteriorating liquidity in the markets for a Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

n  Market Price Variance Risk — Individual Shares of a Fund that are listed for trading on the Exchange can be bought and sold in the secondary market at market prices. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares. There may be times when the market price and the NAV vary significantly, and you may pay more than NAV when buying Shares on the secondary market (a premium), and you may receive less than NAV when you sell those Shares (a discount). The market price of Shares, like the price of any exchange-traded security, includes a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. In times of severe market disruption, the bid-ask spread often increases significantly. This means that Shares may trade at a discount to NAV and the discount is likely to be greatest when the price of Shares is falling fastest, which may be the time that you most want to sell your Shares. A Fund's investment results are measured based upon the daily NAV of a Fund over a period of time. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by those creating and redeeming directly with a Fund.

n  International Closed Market Trading Risk — A Fund's underlying securities may trade on foreign exchanges that are closed when the Exchange is open; consequently, events may transpire while such foreign exchanges are closed but the Exchange is open that may change the value of such underlying securities relative to their last quoted prices on such foreign exchanges. Because a Fund generally relies on the last quoted prices for such securities when calculating its NAV, such events may cause Shares to trade at a premium or discount to NAV.

n  Authorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for a Fund. In addition, there is no obligation for market makers to make a market in a Fund's shares or for Authorized Participants to submit purchase or redemption orders for Creation Units. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

n  Intraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of a Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of a Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. For securities traded outside of the U.S., the IIV calculations are based on local market prices and may not reflect events that occur subsequent to the local market's close which could affect premiums and discounts between the IIV and the market price of a Fund's Shares. In addition, the IIV is based on the published Deposit Securities and not on a Fund's actual holdings. A Fund, the Adviser and their affiliates are not involved in, or responsible for, any aspect of the calculation or dissemination of the IIV and make no warranty as to the accuracy of these calculations.

n  Foreign Investing Risk — Foreign investing risk is the possibility that the value of a Fund's investments in foreign securities will decrease because of currency exchange-rate fluctuations; foreign market illiquidity; emerging-market risk; increased price volatility; uncertain political

Risk Factors (continued)

conditions; exchange control regulations; foreign ownership limits; different accounting, reporting, and disclosure requirements; less publicly available information about foreign issuers; difficulties in obtaining legal judgments; and foreign withholding taxes, among other challenges on non-U.S. investments. Foreign investing may result in a Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies. Foreign investments may be more difficult to value than U.S. securities. Risks that require additional consideration are:

n  Currency Risk — Investments in foreign currencies and in securities that trade in, or receive revenues in, or in derivatives that provide exposure to, foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar. Any such decline may erode or reverse any potential gains from an investment in securities denominated in foreign currency or may widen existing loss. Currency rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates; intervention (or the failure to intervene) by governments, central banks or supranational entities; the imposition of currency controls; or other political developments in the United States or abroad.

n  Depositary Receipts Risk — Foreign securities may trade in the form of depositary receipts, which include ADRs and GDRs (collectively "Depositary Receipts"). To the extent the Fund acquires Depositary Receipts through banks that do not have a contractual relationship with the foreign issuer of the security underlying the Depositary Receipts to issue and service such unsponsored Depositary Receipts, the Fund may not become aware of and be able to respond to corporate actions such as stock splits or rights offerings involving the foreign issuer in a timely manner. In addition, the lack of information may result in inefficiencies in the valuation of such instruments. Investment in Depositary Receipts does not eliminate all the risks inherent in investing in securities of non-U.S. issuers. The market value of Depositary Receipts is dependent upon the market value of the underlying securities and fluctuations in the relative value of the currencies in which the Depositary Receipts and the underlying securities are quoted.

n  Political Risk — Political risk includes a greater potential for coups d'état, revolts, and expropriation by governmental organizations.

n  European Economic Risk — In June 2016, the United Kingdom ("UK") approved a referendum to leave the European Union ("EU"), commonly referred to as "Brexit." The impact of Brexit is so far uncertain. The effect on the UK's economy will likely depend on the nature of trade relations with the EU following its exit. On March 29, 2017, Prime Minister Theresa May provided formal notification of the UK's intention to withdraw from the EU pursuant to Article 50 of the Treaty of Lisbon. While the UK is scheduled to leave the EU, no date is certain at this time. The UK's decision to leave the EU may cause increased volatility and have a significant adverse impact for some time on world financial markets, other international trade agreements, and the UK and European economies, as well as the broader global economy.

n  Index Risk — Each Fund attempts to track the performance of a specific index. An index is an unmanaged group of securities whose overall performance is used as a standard to measure investment performance of a particular market. Each Fund will be negatively affected by general declines in the securities and asset classes represented in the Index. In addition, because the Fund is not "actively" managed, unless a specific security is removed from the Index, the Fund generally would not sell a security because the security's issuer was in financial trouble. Each Fund also does not attempt to take defensive positions under any market conditions, including declining markets. Therefore, the Fund's performance could be

Risk Factors (continued)

lower than funds that may actively shift their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline or a decline in the value of one or more issuers. Additionally, each Fund typically will not match the performance of its index because the performance of its Index does not factor in the costs of buying, selling, and holding stocks or other operating expenses and costs of the Fund.

n  Large-Capitalization Company Risk — Investments in large-capitalization companies may go in and out of favor based on market and economic conditions and may underperform other market segments. Some large-capitalization companies may be unable to respond quickly to new competitive challenges and attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion. As such, returns on investments in stocks of large-capitalization companies could trail the returns on investments in stocks of small- and mid-capitalization companies.

n  Liquidity Risk — Certain securities held by a Fund may be difficult (or impossible) to buy or sell at the time and at the price the Fund would like due to a variety of factors, including general market conditions, the perceived financial strength of the issuer, specific restrictions on resale of the securities, infrequent trading, or lack of market participants. Liquidity is a general investment risk that potentially could impact any security, but funds that invest in foreign or emerging market securities, derivatives, or other structured investments, which all have experienced periods of illiquidity, generally are subject to greater liquidity risk than funds that do not invest in these types of securities. The Fund also may experience reduced liquidity if it has unusually high redemption requests. Reduced liquidity means that the Fund may have difficulty meeting redemptions requests, be unable to achieve its desired level of exposure to a certain market or sector, need to dispose of certain securities, or forgo investment opportunities. It also could adversely impact the valuation of certain securities. In addition, reduced liquidity could impact the Fund's performance negatively.

n  Mid-Capitalization Company Risk — Investments in mid-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

n  Momentum Risk — Momentum investing entails investing more in securities that exhibit persistence in relative performance evidenced by better recent price performance compared to other securities. These securities may be more volatile than a broad cross-section of securities, and momentum may be an indicator that a security's price is peaking. Momentum can turn quickly and cause significant variation from other types of investments. The Fund may experience significant losses if momentum stops, turns or otherwise behaves differently than predicted.

n  Rebalancing Risk — In purchasing and selling securities to rebalance its portfolio, a Fund will pay more in brokerage commissions than it would without a rebalancing policy. As a result of the need to rebalance, the Fund also has less flexibility in the timing of purchases and sales of securities than it would otherwise, and the rebalancing may result in high portfolio turnover. While we will attempt to minimize any adverse impact to a Fund or its shareholders, the Fund may have a higher proportion of capital gains and a lower return than a fund that does not have a rebalancing policy.

n  Regulatory Risk — Each Fund is subject to regulatory risk, which is the risk that legislative, regulatory, or tax policies or developments may have an adverse impact on the value of the Fund's investments and the Fund's NAV.

Risk Factors (continued)

n  Sampling Risk — The Fund's use of a representative sampling strategy could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer or a small number of issuers of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

n  Seed Investor or Large Shareholder Risk — Certain large shareholders, including other funds advised by the Adviser, may from time to time own a substantial amount of the Fund's shares. In addition, seed investors, such as the Adviser, an affiliate of the Adviser, an Authorized Participant, a lead market maker, or other entity, may contribute all or a majority of the assets in the Fund to facilitate commencement of the Fund or to facilitate the Fund's achieving a specified size or scale. To the extent a seed investor in the Fund is an entity subject to domestic and/or international banking regulations, changes in those regulations (e.g., capital requirements) or in the seed investor's financial status may cause or require the seed investor to redeem its investment in the Fund when it otherwise would not choose to redeem that investment. There is a risk that such large shareholders or seed investors may redeem their investments in the Fund, which could have a significant negative impact on the Fund's NAV, market price, and brokerage costs.

n  Small-Capitalization Company Risk — Investments in small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, making it difficult for a Fund to buy and sell them at the time and price desired, and these issuers often face greater business risks. Small-capitalization companies typically are less financially stable than larger, more established companies, and may depend on a small number of key personnel, making them vulnerable to loss of personnel. These companies also generally have less diverse product lines than larger capitalization companies and are more susceptible to adverse developments related to their products.

n  Stock Market Risk — Because the Funds invest in common stocks and preferred securities, it is subject to stock market risk. A company's stock price in general may decline over short or even extended periods of time, regardless of the success or failure of a company's operations. Stock markets tend to run in cycles, with periods when stock prices generally go up, and periods when stock prices generally go down. However, stock markets also can move up and down rapidly or unpredictably, based on overall economic conditions and other factors. Changes in the financial condition of a single issuer can impact a market as a whole.

Market turmoil may be reflected in perceptions of economic uncertainty, price volatility in the equity and debt markets, and fluctuating trading liquidity. In response, governments may adopt a variety of fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs, and lower interest rates. An unexpected or quick reversal of these policies could increase volatility in the equity and debt markets. Market conditions and economic risks could have a significant effect on domestic and international economies, and could add significantly to the risks of increased volatility for a Fund. Equity securities tend to be more volatile than debt securities.

n  Computer Systems Risk — In addition, markets and market participants increasingly rely upon both publicly available and proprietary information data systems. Data imprecision, software or other technology malfunctions, programming inaccuracies, unauthorized use or access, and similar circumstances may impair the performance of these systems and may have an adverse impact upon a single issuer, a group of issuers, or the market at large. In certain cases, an exchange or market may close or issue trading halts on either specific securities or even the entire market, which may result in a Fund being, among other things, unable to buy or sell certain securities or financial instruments or accurately price its investments.

Risk Factors (continued)

n  Tracking Error Risk — Tracking error is the divergence of a Fund's performance from that of the Index. The performance of a Fund may diverge from that of its Index for a number of reasons, such as the use of representative sampling (if applicable), transaction costs, a Fund's holding of cash, differences in accrual of dividends, changes to the Index, tax considerations, rebalancing, or new or existing regulatory requirements. Unlike a Fund, the returns of the Index are not reduced by investment and other operating expenses, including the trading costs associated with implementing changes to its portfolio of investments. Tracking error risk may be heightened during times of market volatility or other unusual market conditions. To the extent that a Fund calculates its NAV based on fair value prices and the value of the Index is based on securities' closing prices (i.e., the value of the Index is not based on fair value prices), a Fund's ability to track the Index may be adversely affected. For tax efficiency purposes, a Fund may sell certain securities to realize losses, which will result in a deviation from the Index.

n  Valuation Risk — The sale price the Fund could receive for a security may differ from the Fund's valuation of the security and may differ from the value used by the Index, particularly for securities that trade in low volume or volatile markets or that are valued using a fair value methodology. The Fund relies on various sources to calculate its NAV. The information may be provided by third parties that are believed to be reliable, but the information may not be accurate due to errors by such pricing sources, technological issues, or otherwise.

n  Value Risk — Value investing entails investing in securities that are inexpensive relative to other securities based on ratios such as price to earnings or price to book. There may be periods when value investing is out of favor, and during which the investment performance of a fund using a value strategy may suffer. In addition, value stocks are subject to the risk that their intrinsic value may never be realized in the market.

The Adviser may use several types of investments in furtherance of the Fund's overall investment objective. The following risks are those that the Adviser does not consider to be principal risks of the Fund. Additional risks are included in the Fund's SAI.

n  Securities Lending Risk — The risk in lending portfolio securities, as with other extensions of credit, consists of the possibility of loss to a Fund due to (i) the inability of the borrower to return the securities, (ii) a delay in receiving additional collateral to adequately cover any fluctuations in the value of securities on loan, (iii) a delay in recovery of the securities, or (iv) the loss of rights in the collateral should the borrower fail financially. In addition, each Fund is responsible for any loss that might result from its investment of the borrower's collateral. In determining whether to lend securities, the Adviser or the Funds' securities lending agent will consider relevant facts and circumstances, including the creditworthiness of the borrower.

n  Investment Company Risk — A Fund's ability to achieve its investment objective may be directly related to the ability of the underlying any funds (including ETFs) held by the Fund to meet their investment objectives. In addition, shareholders of the Fund will indirectly bear the fees and expenses of the underlying investment companies. Underlying investment vehicles are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. Lack of liquidity in an ETF could result in an ETF being more volatile than the underlying portfolio of securities.

Management of the Funds

How to Buy and Sell Shares

Shares of each Fund will be listed for trading on the Exchange under the ticker symbols listed on the cover of this Prospectus. Share prices are reported in dollars and cents per Share. Shares can be bought and sold on the secondary market throughout the trading day like other publicly traded shares, and shares typically trade in blocks of less than a Creation Unit. There is no minimum investment required. Shares may only be purchased and sold on the secondary market when the Exchange is open for trading. The Exchange is open for trading Monday through Friday and is closed on weekends and the following holidays, as observed: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

When buying or selling Shares through a broker, you will incur customary brokerage commissions and charges. The commission is often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell smaller amounts of Shares. You may also pay some or all of the spread between the bid and the offered price in the secondary market on each leg of a round trip (purchase and sale) transaction. The spread varies over time for shares of the Fund based on the Fund's trading volume and market liquidity, and is generally lower if a Fund's Shares have more trading volume and market liquidity and higher if a Fund's Shares have little trading volume and market liquidity.

Only an Authorized Participant ("AP") may engage in creation or redemption transactions directly with the Fund. The Funds' APs are institutions and large investors, such as market makers or other large broker-dealers, which have entered into a Participation Agreement with the Funds' Distributor to undertake the responsibility of obtaining or selling the underlying assets needed to purchase or redeem, respectively, Creation Units of the Funds. APs may acquire Shares directly from a Fund, and APs may tender their Shares for redemption directly to a Fund, at NAV per share only in large blocks, or Creation Units, of 50,000 shares. Purchases and redemptions directly with a Fund must follow the Funds' procedures, which are described in the SAI.

The Funds may liquidate and terminate at any time without shareholder approval.

Share Trading Prices

The trading prices of a Fund's Shares in the secondary market generally differ from the Fund's daily NAV and are affected by market forces such as the supply of and demand for ETF shares and shares of underlying securities held by the Fund, economic conditions and other factors. Information regarding the intraday indicative value ("IIV") of a Fund will be disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund's shares are primarily listed or by market data vendors or other information providers. The IIV is based on the current market value of the securities and/or cash included in a Fund's published basket of securities. However, the IIV should not be viewed as a "real-time" update of the NAV per share of a Fund because the approximate value may not be calculated in the same manner as the NAV, which is computed once a day, generally at the end of the business day. The IIV does not necessarily reflect the precise composition of the current portfolio of securities and instruments held by a Fund at a particular point in time or the best possible valuation of the current portfolio. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV may not reflect estimated accrued interest, dividends and other income, or Fund expenses. The IIV generally is determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities and instruments included in a Fund's IIV basket. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Funds are not involved in, or responsible for, the calculation or dissemination of

How to Buy and Sell Shares (continued)

the approximate value of the Shares and the Funds do not make any warranty as to the accuracy of these values.

Book Entry

Shares are held in book entry form, which means that no stock certificates are issued. The Depository Trust Company ("DTC") or its nominee is the record owner of all outstanding Shares of the Funds and is recognized as the owner of all Shares for all purposes.

Investors owning shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for all shares. Participants in DTC include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book entry or "street name" form.

Frequent Purchases and Redemptions of Fund Shares

Each Fund's Shares can only be purchased and redeemed directly from a Fund by APs in Creation Units. Direct trading by APs is critical to ensuring that a Fund's Shares trade at or close to NAV. The cash to be contributed to (or received from) the Fund in connection with a Creation Unit generally is negligible compared to the total amount of the trade. The Funds with exposure to non-U.S. securities employ fair valuation pricing to minimize arbitrage opportunities that attempt to exploit the differences between a security's market quotation and its fair value. In addition, the Funds impose transaction fees on purchases and redemptions of Shares to cover the custodial and other costs incurred by the Funds in effecting trades. These fees increase if an investor substitutes cash in part or in whole for securities, reflecting the fact that a Fund's trading costs increase in those circumstances.

The vast majority of trading in a Fund's Shares occurs on the secondary market. Because the secondary market trades do not directly involve the Funds, it is unlikely those trades would cause the harmful effects of market timing, including dilution, disruption of portfolio management, increases in a Fund's trading costs and the realization of capital gains.

Given this structure, the Board has determined that it is not necessary to monitor for frequent in-kind purchases and redemptions of Shares or market timing activity by the APs or on the Shares' secondary market.

Other Payments to Financial Intermediaries

If you purchase Fund shares through an investment professional, a broker dealer, or other financial intermediary, the Fund may pay for sub-transfer agent, recordkeeping and/or similar administrative services. In addition, Victory Capital (and its affiliates) may make substantial payments out of its own resources, including the profits from the advisory fees Victory Capital receives from the Funds, to affiliated and unaffiliated dealers or other investment professionals and service providers for distribution, administrative and/or shareholder servicing activities. Victory Capital also may reimburse the Distributor (or the Distributor's affiliates) for making these payments. Some of these distribution-related payments may be made to dealers or other investment professionals for marketing, promotional or related expenses; these payments are often referred to as "revenue sharing." In some circumstances, these types of payments may create an incentive for a dealer or investment professional or its representatives to recommend or offer shares of the Funds to its customers. You should ask your dealer or investment professional for more details about any such payments it receives.

Distribution and Service Plan

The Funds have adopted a distribution and service plan ("Plan") pursuant to Rule 12b-1 under the 1940 Act. Under the Plan, the Funds are authorized to pay distribution fees to the distributor and other firms that provide distribution and shareholder services ("Service Providers"). If a Service Provider provides these services, the Funds may pay fees at an annual rate not to exceed 0.25% of average daily net assets, pursuant to Rule 12b-1 under the1940 Act.

No distribution or service fees are currently paid by the Funds and there are no current plans to impose these fees. In the event Rule 12b-1 fees were charged, over time they would increase the cost of an investment in the Funds.

Distributions and Taxes

Unlike interests in conventional mutual funds, which typically are bought and sold from and to a fund only at closing NAVs, each Fund's Shares are traded throughout the day in the secondary market on a national securities exchange on an intra-day basis and are created and redeemed in-kind and/or for cash in Creation Units at each day's next calculated NAV. In-kind arrangements are designed to protect ongoing shareholders from the adverse effects on a Fund's portfolio that could arise from frequent cash redemption transactions. In a conventional mutual fund, redemptions can have an adverse tax impact on taxable shareholders if the mutual fund needs to sell portfolio securities to obtain cash to meet net fund redemptions. These sales may generate taxable gains for the ongoing shareholders of the mutual fund, whereas the Shares' in-kind redemption mechanism generally will not lead to a tax event for the Fund or its ongoing shareholders.

Ordinarily, dividends from net investment income, if any, are declared and paid quarterly for the US Fund and US Small Cap Fund and semi-annually for the International Funds. Each Fund distributes its net realized capital gains, if any, to shareholders annually.

Distributions in cash may be reinvested automatically in additional whole shares only if the broker through whom you purchased shares makes such option available.

As with any investment, you should consider how your investment in shares will be taxed. The tax information in this Prospectus is provided as general information. You should consult your own tax professional about the tax consequences of an investment in shares.

Unless your investment in shares is made through a tax-exempt entity or tax-deferred retirement account, such as an individual retirement account, you need to be aware of the possible tax consequences when:

n  A Fund makes distributions,

n  You sell your shares listed on the Exchange, and

n  You purchase or redeem Creation Units.

Taxes on Distributions

As stated above, each Fund ordinarily declares and pays dividends from net investment income, if any, quarterly or semi-annually. The Funds may also pay a special distribution at the end of a calendar year to comply with federal tax requirements. Distributions from a Fund's net investment income, including net short-term capital gains, if any, are taxable to you as ordinary income, except that a Fund's dividends attributable to its "qualified dividend income" (i.e., dividends received on stock of most domestic and certain foreign corporations with respect to which a Fund satisfies certain holding period and other restrictions), if any, generally are taxable to non-corporate shareholders at preferential rates. A part of a Fund's dividends also may be eligible for the dividends-received deduction allowed to corporations, subject to similar restrictions.

In general, your distributions are subject to federal income tax when they are paid, whether you take them in cash or reinvest them in a Fund (if that option is available). Distributions reinvested in additional shares of a Fund through the means of a dividend reinvestment service, if available, will be taxable to shareholders acquiring the additional shares to the same extent as if such distributions had been received in cash. Distributions of net long-term capital gains, if any, in excess of net short-term capital losses are taxable as long-term capital gains (at the 20% maximum rate referred to above for non-corporate shareholders), regardless of how long you have held the shares.

Distributions in excess of a Fund's current and accumulated earnings and profits are treated as a tax-free return of capital to the extent of your basis in the shares and as capital gain thereafter. A distribution will reduce a Fund's NAV per Share and may be taxable to you

Distributions and Taxes (continued)

as ordinary income or capital gain (as described above) even though, from an investment standpoint, the distribution may constitute a return of capital.

By law, the Funds are required to withhold 24% of your distributions and redemption proceeds if you have not provided the Funds with a correct Social Security number or other taxpayer identification number and in certain other situations.

Taxes on Exchange-Listed Share Sales

Any capital gain or loss realized upon a sale of shares is generally treated as long-term capital gain or loss if the shares have been held for more than one year and as short-term capital gain or loss if the shares have been held for one year or less. The ability to deduct capital losses from sales of shares may be limited.

Taxes on Purchase and Redemption of Creation Units

An AP who exchanges securities for Creation Units generally will recognize a gain or a loss equal to the difference between the market value of the Creation Units at the time of the exchange and the sum of the exchanger's aggregate basis in the securities surrendered plus any Cash Component it pays. An AP who exchanges Creation Units for securities will generally recognize a gain or loss equal to the difference between the exchanger's basis in the Creation Units and the sum of the aggregate market value of the securities received plus any cash equal to the difference between the NAV of the shares being redeemed and the value of the securities. The Internal Revenue Service ("Service"), however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing "wash sales" or for other reasons. Persons exchanging securities should consult their own tax advisor with respect to whether wash sale rules apply and when a loss might be deductible.

Any capital gain or loss realized upon redemption of Creation Units is generally treated as long-term capital gain or loss if the shares have been held for more than one year and as short-term capital gain or loss if the shares have been held for one year or less.

If you purchase or redeem Creation Units, you will be sent a confirmation statement showing how many shares you purchased or sold and at what price. See "Taxes" in the SAI for a description of the requirement regarding basis determination methods applicable to Share redemptions and the Fund's obligation to report basis information to the Service.

The foregoing discussion summarizes some of the possible consequences under current federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. Consult your personal tax advisor about the potential tax consequences of an investment in the shares under all applicable tax laws.

Other Information

Investments by Investment Companies

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies, including Shares of the Funds. Registered investment companies are permitted to invest in the Funds beyond the limits set forth in Section 12(d)(1) subject to certain terms and conditions set forth in an SEC exemptive order issued to the Adviser, including that such investment companies enter into an agreement with the Trust on behalf of the Funds.

Continuous Offering

The method by which Creation Units of Shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Units of Shares are issued and sold by the Funds on an ongoing basis, a "distribution," as such term is used in the Securities Act of 1933, as amended (the "Securities Act"), may occur at any point. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent Shares and sells the Shares directly to customers or if it chooses to couple the creation of a supply of new Shares with an active selling effort involving solicitation of secondary market demand for Shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a characterization as an underwriter.

Broker-dealer firms should also note that dealers who are not "underwriters" but are effecting transactions in Shares, whether or not participating in the distribution of Shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. As a result, broker-dealer firms should note that dealers who are not "underwriters" but are participating in a distribution (as contrasted with engaging in ordinary secondary market transactions) and thus dealing with the Shares that are part of an overallotment within the meaning of Section 4(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the Securities Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the Securities Act is only available with respect to transactions on a national exchange.

Dealers effecting transactions in the Funds' Shares, whether or not participating in this distribution, are generally required to deliver a Prospectus. This is in addition to any obligation of dealers to deliver a Prospectus when acting as underwriters.
