DEFIANCE RETAIL KINGS ETF SUMMARY

Investment Objective

The Defiance Retail Kings ETF (the "Fund" or the "Retail Kings ETF") seeks long-term capital appreciation.

Fees and Expenses of the Fund

The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund ("Shares"). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.


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

Management Fees			0.79%
Distribution and/or Service (12b-1) Fees			0.00%
Other Expenses*			0.00%
Total Annual Fund Operating Expenses			0.79%

*Estimated for the current fiscal year.

Expense 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 and then continue to hold or redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:


1 Year			3 Years
$81			$252

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when 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. Because the Fund is newly organized, portfolio turnover information is not yet available.

Principal Investment Strategies

The Fund is an actively managed exchange-traded fund ("ETF") that seeks to achieve its investment objective by investing in equity securities, including American depositary receipts ("ADRs"), of "Retail Kings." The Fund defines Retail Kings as U.S.-listed companies identified by the retail investor sentiment Model (defined below) that achieve high scores according to the Momentum Scoring System (defined below) based on bullish momentum factors. The Fund's investment adviser, Defiance ETFs, LLC (the "Adviser"), believes that retail investors' online activity and digital sentiment serve as leading indicators of bullish stock momentum. The Fund invests primarily in common stocks of U.S.-listed companies.

Although the Fund may invest in companies that are classified as "retailers" if they meet certain investment criteria described below, the Fund does not invest primarily in retailers as part of its principal investment strategy.

To select investments for the Fund's portfolio, the Adviser first utilizes an exclusive, proprietary, retail investor sentiment model (the "Model") developed by Futurum Equities, the Fund's sponsor (the "Sponsor"). The Model seeks to identify the equity securities of companies emerging as favorites or trending leaders in online retail investor communities, platforms and forums focused on investing in the stock market. These stocks and their issuers exhibit elevated retail investor sentiment as measured by digital sentiment analysis as well as online engagement trends and social activity. In addition, the Model evaluates retail investors' perception of such stocks, the brand quality of companies, and insider participation with respect to trading activity. The Model further evaluates companies for: 1) future vendor relevance, 2) fundamental resilience, and 3) competitive moat and intellectual property advantage, as defined below. The Model identifies the top 100 companies (the "Eligible Universe") from a starting universe of all U.S.-listed companies with a minimum market capitalization of $200 million (i.e., the Model can select large-, mid-, and small-capitalization companies).

•Future Vendor Relevance- The Model evaluates companies for their potential to serve as critical vendors within long-term secular growth themes. The Model seeks to identify businesses positioned to benefit from emerging technological and structural trends.

•Fundamental Resilience-The Model screens companies for financial durability, including revenue growth, margin profile, and balance sheet strength, with a focus on their ability to compound value across varying market cycles.

•Competitive Moat and Intellectual Property Advantage- The Model selects companies with a demonstrated competitive moat, including proprietary intellectual property, differentiated platform dynamics, or ecosystem advantages that suggest potential for sustained market leadership. Within the Model, "competitive moat" means the defensibility and persistence of retail investor interest in a company, as compared to interest in other companies, making such company more likely to sustain prominence as a retail investor favorite over time.

The Sponsor is not affiliated with ETF Series Solutions, the Adviser, or the Fund's sub-adviser.

The Adviser next applies a momentum overlay to rank companies in the Eligible Universe using the Adviser's proprietary momentum scoring system (the "Momentum Scoring System"). The Momentum Scoring System assigns each security in the Eligible Universe a composite score derived from multiple quantitative factors, including:

•Price Trend Persistence: Measures sustained upward price movement across multiple timeframes (e.g., 3-, 6-, and 12-month trailing returns).

•Relative Strength Ranking: Compares each security's performance against the broader universe and relevant sector benchmarks.

•Volatility-Adjusted Returns: Incorporates Sharpe-like measures to prioritize securities with strong risk-adjusted momentum.

•Breadth and Confirmation Metrics: Evaluates participation across trading volume, moving averages, and breakout thresholds to confirm trend durability.

The Adviser selects the top 30-50 Eligible Universe securities, as ranked by the Momentum Scoring System, for inclusion in the Fund's portfolio at each rebalance. This systematic process is designed to capture leadership within innovation-driven sectors, such as, currently, the financials, industrials, and information technology sectors, providing increased exposure to companies that demonstrate accelerating price performance and improving investor sentiment.

The Adviser rebalances the Fund's portfolio at least quarterly and may sell a security for the Fund when, in its opinion, one or more of the following occurs, among other reasons: 1) the Model identifies a more attractive security, 2) there are significant changes to a security's fundamental factors, and 3) the risk profile of a particular security has changed. The Fund may engage in frequent and active trading as a result of its strategy. The Fund may also engage in securities lending as part of the Fund's principal investment strategy. The Fund is non-diversified.

Under normal market conditions, the Fund will invest at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of Retail Kings companies.

The Fund's portfolio holdings will generally be equally weighted upon the Adviser's rebalance of the Fund's portfolio. At its inception, the Fund may have significant exposure to the information technology sector as well as the aerospace & defense industry and the semiconductor & semiconductor equipment industry; however, this may change from time to time.

Principal Investment Risks

The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a "principal risk" of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund's net asset value per share ("NAV"), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund's Prospectus titled "Additional Information About the Fund".

•ADR Risk. ADRs involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. ADRs listed on U.S. exchanges are issued by banks or trust companies, and ADRs entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares.

•Aerospace and Defense Companies Industry Risk.Government aerospace and defense regulation and spending policies can significantly affect the aerospace and defense industry because many companies involved in the aerospace and defense industry rely to a large extent on U.S. (and other) government demand for their products and services. There are significant inherent risks in contracting with the U.S. government that could have a material adverse effect on the business, financial condition and results of operations of industry participants.

•Equity Market Risk. The equity securities held in the Fund's portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia's invasion of Ukraine, acts of terrorism, spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19

virus), recessions, rising inflation, trade wars and tariffs, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund's portfolio securities or other instruments and could result in disruptions in the trading markets.

•ETF Risks. The Fund is an ETF, and, as a result of an ETF's structure, it is exposed to the following risks:

◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants ("APs"). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares.Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

◦Trading. Although Shares are listed for trading on The Nasdaq Stock Market LLC (the "Exchange") and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund's underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

•Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser's success or failure to implement investment strategies for the Fund.

•Market Capitalization Risk

◦Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

◦Mid-Capitalization Investing.The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.

◦Small-Capitalization Investing.The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller capitalization companies than for larger, more established companies.

•Models and Data Risk. When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. The models used to construct the Fund's portfolio are predictive in nature. The use of predictive models has inherent risks. For example, such models may incorrectly forecast future behavior, leading to potential losses. In addition, in unforeseen or certain low-probability scenarios (often involving a market disruption of some kind), such models may produce unexpected results, which can result in losses for the Fund. Furthermore, because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data.

sign that the securities' prices have peaked. Momentum can change quickly and result in significant variation in performance from other types of investments. The Fund may experience significant losses if momentum stops, turns or otherwise behaves differently than predicted.

•New Fund Risk. The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision.

•Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund's volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund's performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code").

•Portfolio Turnover Risk. The Fund may trade all or a significant portion of the securities in its portfolio in connection with proprietary retail sentiment score shifts. A high portfolio turnover rate increases transaction costs, which may increase the Fund's expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

•Retail Investor Sentiment Risk. Investments in the equity securities of issuers that exhibit elevated retail investor sentiment may underperform or be more volatile than investments in the broader equity market and/or equities that do not garner retail investor interest. Positive sentiment across digital platforms, communities, or forums with respect to a stock or issuer may not result in, or correlate with, positive stock performance. The Model's assessment of retail investor sentiment relies on relatively new and untested social media analytics. Further, online retail investors may exhibit positive sentiment toward equity securities that are disfavored by the broader market, including institutional Wall Street investment firms. Contributors to online investment forums may not have the educational background, qualifications, or industry experience of more established Wall Street investors. Further, any investments selected by the Model that emerge from these digital communities are subject to bias and self-interest since these online communities and investment forums have no fiduciary duty to the public, including the Fund and its shareholders. In particular, social media posts evaluated by the Model may be published in an attempt to manipulate the market or alter public perception of a company stock. There is no guarantee that the Model will be successful in screening out biased or manipulative social media posts when evaluating retail investor sentiment online.

•Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.

◦Financials Sector Risk. This sector, which includes banks, insurance companies, and financial service firms, can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and fallout from the housing and sub-prime mortgage crisis. Banks, in particular, are subject to volatile interest rates, severe price competition, and extensive government oversight and regulation, which may limit certain economic activities available to banks, impact their fees and overall profitability, and establish capital maintenance requirements. In addition, banks may have concentrated portfolios of loans or investments that make them vulnerable to economic conditions that affect that industry. Insurance companies are subject to similar risks as banks, including adverse economic conditions, changes in interest rates, increased competition and government regulation, but insurance companies are more at risk from changes in tax law, government imposed premium rate caps, and catastrophic events, such as earthquakes, floods, hurricanes and terrorist acts. This sector has experienced significant losses in the recent past, and the impact of higher interest rates, more stringent capital requirements, and of recent or future regulation on any individual financial company, or on the sector as a whole, cannot be predicted. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in the financial sector and have caused significant losses.

◦Industrials Sector Risk. The industrials sector can be significantly affected by, among other things, worldwide economic growth, supply and demand for specific products and services, rapid technological developments, international political and economic developments, environmental issues, tariffs and trade barriers, and tax and governmental regulatory policies. As the demand for, or prices of, industrials increase, the value of the Fund's investments generally would be expected to also increase. Conversely, declines in the demand for, or prices of, industrials generally would be expected to contribute to declines in the value of such securities. Such declines may occur quickly and without warning and may negatively impact the value of the Fund and your investment.

smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

•Securities Lending Risk.There are certain risks associated with securities lending, including the risk that the borrower may fail to return the securities on a timely basis or even the loss of rights in the collateral deposited by the borrower, if the borrower should fail financially. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. As a result, the Fund may lose money.

•Semiconductors and Semiconductor Equipment Industry Risk.Competitive pressures, intense competition, aggressive pricing, technological developments, changing demand, research and development costs, availability and price of components and product obsolescence can significantly affect companies operating in the semiconductors and Semiconductor Equipment industry. Reduced demand for end-user products, under-utilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductors and Semiconductor Equipment industry. Semiconductor companies typically face high capital costs and may be heavily dependent on intellectual property rights. The semiconductors and Semiconductor Equipment industry is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. The stock prices of companies in the semiconductors and Semiconductor Equipment industry have been and likely will continue to be extremely volatile.

Performance

Performance information for the Fund is not included because the Fund had not yet commenced operations as of the date of this Prospectus. In the future, performance information for the Fund will be presented in this section. Updated performance information will be available on the Fund's website at www.defianceetfs.com.

Portfolio Management


Adviser			Defiance ETFs, LLC
Sub-Adviser			Penserra Capital Management LLC ("Penserra" or the "Sub-Adviser")
Portfolio Managers			Sylvia Jablonski, Chief Executive Officer and Chief Investment Officer of the Adviser, is primarily responsible for the day-to-day management of the Fund since its inception in December, 2025.
			Ms. Jablonski provides her recommendations to Dustin Lewellyn, CFA, Managing Director, Ernesto Tong, CFA, Managing Director, and Christine Johanson, CFA, Director and Senior Portfolio Manager of the Sub-Adviser. Messrs. Lewellyn and Tong and Ms. Johanson have been jointly and primarily responsible for the trade management of the Fund since its inception in December, 2025.

Purchase and Sale of Shares

Shares are listed on the Exchange, and individual Shares may only be bought and sold in the secondary market through brokers at market prices, rather than NAV. Because Shares trade at market prices rather than NAV, Shares may trade at a price greater than NAV (premium) or less than NAV (discount).

The Fund issues and redeems Shares at NAV only in large blocks known as "Creation Units," which only APs (typically, broker-dealers) may purchase or redeem. The Fund generally issues and redeems Creation Units in exchange for a portfolio of securities and/or a designated amount of U.S. cash.

Investors may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares in the secondary market (the "bid-ask spread"). Recent information about the Fund, including its NAV, market price, premiums and discounts, and bid-ask spreads is available on the Fund's website at www.defianceetfs.com.

Tax Information

Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is in an individual retirement account ("IRA") or other tax-advantaged account. Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an "Intermediary"), the Adviser or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary's website for more information.

ADDITIONAL INFORMATION ABOUT THE FUND

Additional Information about the Fund's Investment Objective

The Fund's investment objective has been adopted as a non-fundamental investment policy and may be changed without shareholder approval upon written notice to shareholders.

Temporary Defensive Positions. From time to time, the Fund may take temporary defensive positions that are inconsistent with its principal investment strategies in attempting to respond to adverse market, economic, political, or other conditions. In such instances, the Fund may hold up to 100% of its assets in cash; short-term U.S. government securities and government agency securities; investment grade money market instruments; money market mutual funds; investment grade fixed-income securities; repurchase agreements; commercial paper; cash equivalents; and ETFs that principally invest in the foregoing instruments. As a result of engaging in these temporary measures, the Fund may not achieve its investment objective.

Additional Information about the Fund's Principal Investment Risks

This section provides additional information regarding the principal risks described in the Fund Summary. As in the Fund Summary, the principal risks below are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk described below is considered a "principal risk" of investing in the Fund, regardless of the order in which it appears. Each of the factors below could have a negative impact on the Fund's performance and trading prices.

•ADR Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying securities of the ADRs in the Fund's portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund's portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares.

•Equity Market Risk. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors including: expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; local, regional or global events such as acts of terrorism or war, including Russia's invasion of Ukraine; and global or regional political, economic, public health, and banking crises. If you held common stock, or common stock equivalents, of any given issuer, you would generally be exposed to greater risk than if you held preferred stocks and debt obligations of the issuer because common stockholders, or holders of equivalent interests, generally have inferior rights to receive payments from issuers in comparison with the rights of preferred stockholders, bondholders, and other creditors of such issuers.

•ETF Risks. The Fund is an ETF, and, as a result of an ETF's structure, it is exposed to the following risks:

◦APs, Market Makers, and Liquidity Providers Concentration Risk.The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares.Investors buying or selling Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers, as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. In addition, secondary market investors will also incur the cost of the difference between the price at which an investor is willing to buy Shares (the "bid" price) and the price at which an investor is willing to sell Shares (the "ask" price). This difference in bid and ask prices is often referred to as the "spread" or "bid-ask spread." The bid-ask spread varies over time for Shares based on trading volume and market liquidity, and the spread is generally lower if Shares have more trading volume and market liquidity and higher if Shares have little trading volume and market liquidity. Further, a relatively small investor base in the Fund, asset swings in the Fund, and/or increased market volatility may cause increased bid-ask spreads.

Due to the costs of buying or selling Shares, including bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

◦Shares May Trade at Prices Other Than NAV.As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund's NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility or periods of steep market declines. The market price of Fund shares during the trading day, like the price of any exchange-traded security, includes a "bid-ask" spread charged by the exchange specialist, market makers or other participants that trade the Fund shares. In times of severe market disruption, the bid-ask spread can increase significantly. At those times, Fund shares are most likely to be traded at a discount to NAV, and the discount is likely to be greatest when the price of Fund shares is falling fastest, which may be the time that you most want to sell your Fund shares. The Adviser believes that, under normal market conditions, large market price discounts or premiums to NAV will not be sustained because of arbitrage opportunities.

◦Trading. Although Shares are listed for trading on the Exchange and may be listed or traded on U.S. and non-U.S. stock exchanges other than the Exchange, there can be no assurance that an active trading market for such Shares will develop or be maintained. Trading in Shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to Exchange "circuit breaker" rules, which temporarily halt trading on the Exchange when a decline in the S&P 500®Index during a single day reaches certain thresholds (e.g., 7%, 13%, and 20%). Additional rules applicable to the Exchange may halt trading in Shares when extraordinary volatility causes sudden, significant swings in the market price of Shares. There can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund's underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

•Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser's success or failure to implement investment strategies for the Fund.

•Market Capitalization Risk.

◦Large-Capitalization Investing Risk. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

◦Mid-Capitalization Investing Risk. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies, but they may also be subject to slower growth than small-capitalization companies during times of economic expansion. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole. Mid-capitalization companies may be particularly sensitive to changes in interest rates, government regulation, borrowing costs, and earnings.

◦Small-Capitalization Investing Risk. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.

•Models and Data Risk. When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. For example, by relying on Models and Data, the Adviser may be induced to buy certain investments at prices that are too high, to sell certain other investments at prices that are too low, or to miss favorable opportunities altogether. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful.

The models used by the Adviser to select the Fund's portfolio are predictive in nature. The use of predictive models has inherent risks. For example, such models may incorrectly forecast future behavior, leading to potential losses on a cash flow and/or a mark-to-market basis. In addition, in unforeseen or certain low-probability scenarios (often involving a market disruption of some kind), such models may produce unexpected results, which can result in losses for the Fund. Furthermore, because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data.

All models rely on correct market data inputs. If incorrect market data is entered into even a well-founded model, the resulting information will be incorrect. However, even if market data is input correctly, "model prices" will often differ substantially from market prices, especially for instruments with complex characteristics, such as derivative instruments.

•Momentum Style Investing Risk. Investing in or having exposure to securities with positive momentum entails investing in securities that have had above-average returns recently. This style of investing is subject to the risk that (1) these securities may be more volatile than a broad cross-section of securities and (2) the returns on securities that have previously exhibited price momentum may be less than the returns on other styles of investing or the overall stock market. High momentum may also be a sign that the securities' prices have peaked. Momentum can change quickly and result in significant variation in performance from other types of investments. The Fund may experience significant losses if momentum stops, turns or otherwise behaves differently than predicted.

•Non-Diversification Risk.The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund's volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund's performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a RIC under Subchapter M of the Code.

•Sector Risk. The Fund's investing approach may result in an emphasis on certain sectors or sub-sectors of the market at any given time. To the extent the Fund invests more heavily in one sector or sub-sector of the market, it thereby presents a more concentrated risk and its performance will be especially sensitive to developments that significantly affect those sectors or sub-sectors. In addition, the value of Shares may change at different rates compared to the value of shares of a fund with investments in a more diversified mix of sectors and industries. An individual sector or sub-sector of the market may have above-average performance during particular periods, but it may also move up and down more than the broader market. The several industries that constitute a sector may all react in the same way to economic, political or regulatory events. The Fund's performance could also be affected if the sectors or sub-sectors do not perform as expected. Alternatively, the lack of exposure to one or more sectors or sub-sectors may adversely affect performance.

◦Financials Sector Risk.Companies in the financial sector of an economy, including banks, insurance companies, and financial service firms, are often subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted.

Certain risks may impact the value of investments in the financial sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets.

Banks, in particular, are subject to volatile interest rates, severe price competition, and extensive government oversight and regulation, which may limit certain economic activities available to banks, impact their fees and overall profitability, and

establish capital maintenance requirements. In addition, banks may have concentrated portfolios of loans or investments that make them vulnerable to economic conditions that affect that industry. Insurance companies are subject to similar risks as banks, including adverse economic conditions, changes in interest rates, increased competition and government regulation, but insurance companies are more at risk from changes in tax law and government imposed premium rate caps. Different segments of the insurance industry can be significantly affected by mortality and morbidity rates, environmental clean-up costs and catastrophic events such as earthquakes, floods, hurricanes and terrorist acts.

The financial sector is also a target for cyber attacks and may experience technology malfunctions and disruptions. In recent years, cyber attacks and technology failures have become increasingly frequent and have caused significant losses.

◦Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund's investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.

•Securities Lending Risk. There are certain risks associated with securities lending, including the risk that the borrower may fail to return the securities on a timely basis or even the loss of rights in the collateral deposited by the borrower, if the borrower should fail financially. As a result, the Fund may lose money. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

PORTFOLIO HOLDINGS INFORMATION

MANAGEMENT

Investment Adviser

Defiance ETFs, LLC serves as the investment adviser and has overall responsibility for the general management and administration of the Fund. The Adviser is located at 78 SW 7th Street, 5th Floor, Miami, Florida 33130, and is an SEC-registered investment adviser. The Adviser was founded in 2018 and arranges for sub-advisory, transfer agency, custody, fund administration, and all other related services necessary for the Fund to operate. The Adviser provides investment advisory services to ETFs, including the Fund.

The Adviser provides oversight of the Sub-Adviser, monitors the Sub-Adviser's buying and selling of securities for the Fund, and reviews the Sub-Adviser's performance.

For the services it provides to the Fund, the Fund pays the Adviser a unified management fee of 0.79%, which is calculated daily and paid monthly, at an annual rate based on the Fund's average daily net assets.

Under the Investment Advisory Agreement (the "Advisory Agreement"), the Adviser has agreed to pay all expenses of the Fund, except for interest charges on any borrowings, dividends and other expenses on securities sold short, taxes, brokerage commissions and other expenses incurred in placing orders for the purchase and sale of securities and other investment instruments, acquired fund fees and expenses, accrued deferred tax liability, extraordinary expenses, distribution fees and expenses paid by the Fund under any distribution plan adopted pursuant to Rule 12b-1 under the 1940 Act, and the unified management fee payable to the Adviser. The Adviser, in turn, compensates the Sub-Adviser from the management fee it receives.

A discussion regarding the basis for the Board of Trustees' approval of the Fund's Advisory Agreement will be available in the Fund's Core Financial Statements that will be filed as part of the Fund's first Form N-CSR.

Sub-Adviser

The Adviser has retained Penserra Capital Management LLC to serve as sub-adviser for the Fund. Penserra is responsible for the day-to-day trade management of the Fund. Penserra is a registered investment adviser and New York limited liability company whose principal office is located at 4 Orinda Way, Suite 100-A, Orinda, California 94563. Penserra provides investment management services to investment companies and other investment advisers. Penserra is responsible for trading portfolio securities for the Fund, including selecting broker-dealers to execute purchase and sale transactions, subject to the supervision of the Adviser and the Board.

For its services, the Sub-Adviser is paid a fee by the Adviser, which fee is calculated daily and paid monthly, at an annual rate of 0.0375% based on the average daily net assets for the Fund, subject to a minimum annual fee of $15,000.

A discussion regarding the basis for the Board of Trustees' approval of the Fund's Sub-Advisory Agreement will be available in the Fund's Core Financial Statements that will be filed as part of the Fund's first Form N-CSR.

Manager of Managers Structure

The Fund and the Adviser have received an exemptive order from the SEC permitting the Adviser (subject to certain conditions and the Board's approval) to select or change sub-advisers without obtaining shareholder approval. The order also permits the Adviser to materially amend the terms of agreements with a sub-adviser (including an increase in the fee paid by the Adviser to the sub-adviser (and not paid by the Fund)) or to continue the employment of a sub-adviser after an event that would otherwise cause the automatic termination of services with Board approval, but without shareholder approval. Shareholders will be notified of any sub-adviser changes.

Portfolio Manager

The portfolio managers are jointly and primarily responsible for various functions related to portfolio management, including, but not limited to, making recommendations (or implementing) with respect to the following: investing cash inflows, implementing investment strategy, researching and reviewing investment strategy, and overseeing members of the portfolio management team with more limited responsibilities.

The Fund's SAI provides additional information about the Portfolio Managers' compensation structure, other accounts managed by the Portfolio Managers, and the Portfolio Managers' ownership of shares in the Fund.

Fund Sponsor

Futurum Equities, the Fund's sponsor (the "Sponsor") has entered into an ETF development agreement with the Adviser. Under the ETF development agreement, the Sponsor has agreed to assist with the development of the Fund and provide strategic support and guidance to the Adviser. As part of the arrangement between the Sponsor and the Adviser, the parties are jointly responsible for certain listing, legal and regulatory costs and expenses in connection with the creation, launch and on-going operation of the Fund. The Sponsor has agreed to cover a set percentage of these start-up and operational costs and, to the extent the Adviser's revenue from the Fund's management fee exceeds these costs, the Sponsor is entitled to receive a share of that revenue equal to the percentage of costs covered by the Sponsor. The Sponsor is not affiliated with ETF Series Solutions, the Adviser, the Sub-Adviser, the Fund's administrator, custodian, transfer agent or the Distributor (defined below), or any of their respective affiliates.

HOW TO BUY AND SELL SHARES

The Fund issues and redeems Shares at NAV only in Creation Units. Only APs may acquire Shares directly from the Fund, and only APs may tender their Shares for redemption directly to the Fund, at NAV. APs must be a member or participant of a clearing agency registered with the SEC and must execute a Participant Agreement that has been agreed to by the Distributor (defined below), and that has been accepted by the Fund's transfer agent, with respect to purchases and redemptions of Creation Units. Once created, Shares trade in the secondary market in quantities less than a Creation Unit.

Most investors buy and sell Shares in secondary market transactions through brokers. Shares are listed for trading on the secondary market on the Exchange and can be bought and sold throughout the trading day like other publicly traded securities.

When buying or selling Shares through a broker, you will incur customary brokerage commissions and charges, and you may pay some or all of the spread between the bid and the offer price in the secondary market on each leg of a round trip (purchase and sale) transaction. In addition, because secondary market transactions occur at market prices, you may pay more than NAV when you buy Shares and receive less than NAV when you sell those Shares.

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.

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. DTC's participants 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" through your brokerage account.

Frequent Purchases and Redemptions of Shares

The Fund imposes no restrictions on the frequency of purchases and redemptions of Shares. In determining not to approve a written, established policy, the Board evaluated the risks of market timing activities by Fund shareholders. Purchases and redemptions by APs, who are the only parties that may purchase or redeem Shares directly with the Fund, are an essential part of the ETF process and help keep Share trading prices in line with NAV. As such, the Fund accommodates frequent purchases and redemptions by APs. However, the Board has also determined that frequent purchases and redemptions for cash may increase tracking error and portfolio transaction costs and may lead to the realization of capital gains. To minimize these potential consequences of frequent purchases and redemptions, the Fund employs fair value pricing and may impose transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by the Fund in effecting trades. In addition, the Fund and the Adviser reserve the right to reject any purchase order at any time.

Determination of Net Asset Value

The Fund's NAV is calculated as of the scheduled close of regular trading on the New York Stock Exchange ("NYSE"), generally 4:00 p.m. Eastern time, each day the NYSE is open for business. The NAV is calculated by dividing the Fund's net assets by its Shares outstanding.

In calculating its NAV, the Fund generally values its assets on the basis of market quotations, last sale prices, or estimates of value furnished by a pricing service or brokers who make markets in such instruments. In particular, the Fund generally values equity securities traded on any recognized U.S. or non-U.S. exchange at the last sale price or official closing price on the exchange or system on which they are principally traded. If such information is not available for a security held by the Fund or is determined to be unreliable, the security will be valued by the Adviser at fair value pursuant to procedures established by the Adviser and approved by the Board (as described below).

Fair Value Pricing

The Adviser has been designated by the Board as the valuation designee for the Fund pursuant to Rule 2a-5 under the 1940 Act. In its capacity as valuation designee, the Adviser has adopted procedures and methodologies to fair value Fund securities whose market prices are not "readily available" or are deemed to be unreliable. For example, such circumstances may arise when: (i) a security has been de-listed or has had its trading halted or suspended; (ii) a security's primary pricing source is unable or unwilling to provide a price; (iii) a security's primary trading market is closed during regular market hours; or (iv) a security's value is materially affected by events occurring after the close of the security's primary trading market. The Board has appointed the Adviser as the Fund's valuation designee to perform all fair valuations of the Fund's portfolio investments, subject to the Board's oversight. Accordingly, the Adviser has established procedures for its fair valuation of the Fund's portfolio investments. Generally, when fair valuing a security held by the Fund, the Adviser will take into account all reasonably available information that may be relevant to a particular valuation including, but not limited to, fundamental analytical data regarding the issuer, information relating to the issuer's business, recent trades or offers of the security, general and/or specific market conditions and the specific facts giving rise to the need to fair value the security. Fair value determinations are made in good faith and in accordance with the fair value methodologies established by the Adviser. Due to the subjective and variable nature of determining the fair value of a security or other investment, there can be no assurance that the Adviser's fair value will match or closely correlate to any market quotation that subsequently becomes available or the price quoted or published by other sources. In addition, the Fund may not be able to obtain the fair value assigned to the security upon the sale of such security.

Delivery of Shareholder Documents - Householding

Householding is an option available to certain investors of the Fund. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Householding for the Fund is available through certain broker-dealers. If you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, please contact your broker-dealer. If you are currently enrolled in householding and wish to change your householding status, please contact your broker-dealer.

Investments by Registered Investment Companies

Section 12(d)(1) of the 1940 Act restricts investments by registered investment companies in the securities of other investment companies, including Shares. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in section 12(d)(1) subject to certain terms and conditions set forth in Rule 12d1-4 under the 1940 Act, including that such investment companies enter into an agreement with the Fund.

DIVIDENDS, DISTRIBUTIONS, AND TAXES

Dividends and Distributions

The Fund intends to pay out dividends, if any, and distribute any net realized capital gains to its shareholders at least annually. The Fund will declare and pay capital gain distributions in cash. Distributions in cash may be reinvested automatically in additional whole Shares only if the broker through whom you purchased Shares makes such option available. Your broker is responsible for distributing the income and capital gain distributions to you.

Taxes

The following discussion is a summary of certain important U.S. federal income tax considerations generally applicable to investments in the Fund. Your investment in the Fund may have other tax implications. Please consult your tax advisor about the tax consequences of an investment in Shares, including the possible application of foreign, state, and local tax laws. This summary does not apply to Shares held in an IRA or other tax-qualified plans, which are generally not subject to current tax. Transactions relating to Shares held in such accounts may, however, be taxable at some time in the future. This summary is based on current tax laws, which may change.

The Fund intends to elect and qualify each year for treatment as a RIC under the Code. If the Fund meets certain minimum distribution requirements, a RIC is not subject to tax at the fund level on income and gains from investments that are timely distributed to shareholders. However, the Fund's failure to qualify as a RIC or to meet minimum distribution requirements would result (if certain relief provisions were not available) in fund-level taxation and, consequently, a reduction in income available for distribution to shareholders.

Unless your investment in Shares is made through a tax-exempt entity or tax-advantaged account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions, when you sell your Shares listed on the Exchange, and when you purchase or redeem Creation Units (APs only).

Taxes on Distributions

The Fund intends to distribute, at least annually, substantially all of its net investment income and net capital gains. For federal income tax purposes, distributions of investment income are generally taxable as ordinary income or qualified dividend income. Taxes on distributions of capital gains (if any) are determined by how long the Fund owned the investments that generated them, rather than

how long a shareholder has owned his or her Shares. Sales of assets held by the Fund for more than one year generally result in long-term capital gains and losses, and sales of assets held by the Fund for one year or less generally result in short-term capital gains and losses. Distributions of the Fund's net capital gain (the excess of net long-term capital gains over net short-term capital losses) that are reported by the Fund as capital gain dividends ("Capital Gain Dividends") will be taxable as long-term capital gains, which for non-corporate shareholders are subject to tax at reduced rates of up to 20% (lower rates apply to individuals in lower tax brackets). Distributions of short-term capital gain will generally be taxable as ordinary income. Dividends and distributions are generally taxable to you whether you receive them in cash or reinvest them in additional Shares.

Distributions reported by the Fund as "qualified dividend income" are generally taxed to non-corporate shareholders at rates applicable to long-term capital gains, provided holding period and other requirements are met. "Qualified dividend income" generally is income derived from dividends paid by U.S. corporations or certain foreign corporations that are either incorporated in a U.S. possession or eligible for tax benefits under certain U.S. income tax treaties. In addition, dividends that the Fund received in respect of stock of certain foreign corporations may be qualified dividend income if that stock is readily tradable on an established U.S. securities market. Corporate shareholders may be entitled to a dividends received deduction for the portion of dividends they receive from the Fund that are attributable to dividends received by the Fund from U.S. corporations, subject to certain limitations. The Fund's investment strategy may limit the amount of distributions eligible for treatment as qualified dividend income in the hands of non-corporate shareholders or eligible for the dividends received deduction for corporate shareholders.

Shortly after the close of each calendar year, you will be informed of the amount and character of any distributions received from the Fund.

In general, your distributions are subject to federal income tax for the year in which they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year. Distributions are generally taxable even if they are paid from income or gains earned by the Fund before your investment (and thus were included in the Shares' NAV when you purchased your Shares).

You may wish to avoid investing in the Fund shortly before a dividend or other distribution, because such a distribution will generally be taxable even though it may economically represent a return of a portion of your investment.

If you are neither a resident nor a citizen of the United States or if you are a foreign entity, distributions (other than Capital Gain Dividends) paid to you by the Fund will generally be subject to a U.S. withholding tax at the rate of 30%, unless a lower treaty rate applies. Gains from the sale or other disposition of Shares by non-U.S. shareholders generally are not subject to U.S. taxation, unless you are a nonresident alien individual who is physically present in the U.S. for 183 days or more per year. The Fund may, under certain circumstances, report all or a portion of a dividend as an "interest-related dividend" or a "short-term capital gain dividend," which would generally be exempt from this 30% U.S. withholding tax, provided certain other requirements are met. Different tax consequences may result if you are a foreign shareholder engaged in a trade or business within the United States or if a tax treaty applies.

The Fund (or a financial intermediary, such as a broker, through which a shareholder owns Shares) generally is required to withhold and remit to the U.S. Treasury a percentage (currently 24%) of the taxable distributions and sale proceeds paid to any shareholder who fails to properly furnish a correct taxpayer identification number, who has underreported dividend or interest income, or who fails to certify that the shareholder is not subject to such withholding.

Taxes When Shares are Sold on the Exchange

Provided that a shareholder holds Shares as capital assets, any capital gain or loss realized upon a sale of Shares generally is treated as a long-term capital gain or loss if Shares have been held for more than one year and as a short-term capital gain or loss if Shares have been held for one year or less. However, any capital loss on a sale of Shares held for six months or less is treated as long-term capital loss to the extent of Capital Gain Dividends paid with respect to such Shares. Any loss realized on a sale will be disallowed to the extent Shares of the Fund are acquired, including through reinvestment of dividends, within a 61-day period beginning 30 days before and ending 30 days after the disposition of Shares. The ability to deduct capital losses may be limited.

The cost basis of Shares of the Fund acquired by purchase will generally be based on the amount paid for the Shares and then may be subsequently adjusted for other applicable transactions as required by the Code. The difference between the selling price and the cost basis of Shares generally determines the amount of the capital gain or loss realized on the sale or exchange of Shares. Contact the broker through whom you purchased your Shares to obtain information with respect to the available cost basis reporting methods and elections for your account.

Taxes on Purchases and Redemptions of Creation Units

An AP having the U.S. dollar as its functional currency for U.S. federal income tax purposes who exchanges securities for Creation Units generally recognizes a gain or a loss. The gain or loss will be equal to the difference between the value of the Creation Units at the time of the exchange and the exchanging AP's aggregate basis in the securities delivered, plus the amount of any cash paid for the Creation Units. An AP who exchanges Creation Units for securities will generally recognize a gain or loss equal to the difference between the exchanging AP's basis in the Creation Units and the aggregate U.S. dollar market value of the securities received, plus

any cash received for such Creation Units. The IRS may assert, however, that a loss that is realized upon an exchange of securities for Creation Units may not be currently deducted under the rules governing "wash sales" (for an AP who does not mark-to-market its holdings), or on the basis that there has been no significant change in economic position. APs exchanging securities should consult their own tax advisor with respect to whether the wash sales rule applies and when a loss might be deductible.

The Fund may include a payment of cash in addition to, or in place of, the delivery of a basket of securities upon the redemption of Creation Units. The Fund may sell portfolio securities to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize investment income and/or capital gains or losses that it might not have recognized if it had completely satisfied the redemption in-kind. As a result, the Fund may be less tax efficient if it includes such a cash payment in the proceeds paid upon the redemption of Creation Units.

Net Investment Income Tax

U.S. individuals with income exceeding specified thresholds are subject to a 3.8% tax on all or a portion of their "net investment income," which includes interest, dividends, and certain capital gains (generally including capital gains distributions and capital gains realized on the sale of Shares). This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts.

Foreign Securities

To the extent that the Fund invests in foreign securities, it may be subject to foreign withholding taxes with respect to dividends or interest the Fund receives from sources in foreign countries. If more than 50% of the total assets of the Fund consist of foreign securities at the end of the Fund's taxable year, the Fund will be eligible to elect to treat some of those taxes as a distribution to shareholders, which would allow shareholders to offset some of their U.S. federal income tax. The Fund (or a financial intermediary, such as a broker) will notify you if it makes such an election and provide you with the information necessary to reflect foreign taxes paid on your income tax return.

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. You also may be subject to state and local tax on Fund distributions and sales of Shares. Consult your personal tax advisor about the potential tax consequences of an investment in Shares under all applicable tax laws. For more information, please see the section entitled "Federal Income Taxes" in the SAI.

DISTRIBUTION

The Distributor, Foreside Fund Services, LLC, a wholly-owned subsidiary of Foreside Financial Group, LLC (d/b/a ACA Group), is a broker-dealer registered with the SEC. The Distributor distributes Creation Units for the Fund on an agency basis and does not maintain a secondary market in Shares. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor's principal address is 190 Middle Street, Suite 301, Portland, Maine 04101.

The Board has adopted a Distribution and Service Plan (the "Plan") pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Plan, the Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year for certain distribution-related activities and shareholder services.

No Rule 12b-1 fees are currently paid by the Fund, and there are no plans to impose these fees. However, in the event Rule 12b-1 fees are charged in the future, because the fees are paid out of the Fund's assets, over time these fees will increase the cost of your investment and may cost you more than certain other types of sales charges.

PREMIUM/DISCOUNT INFORMATION

Information regarding how often Shares traded on the Exchange at a price above (i.e., at a premium) or below (i.e., at a discount) the NAV per Share is available, free of charge, on the Fund's website at www.defianceetfs.com.

ADDITIONAL NOTICES

Shares are not sponsored, endorsed, or promoted by the Exchange. The Exchange is not responsible for, nor has it participated in the determination of the timing, prices, or quantities of Shares to be issued, nor in the determination or calculation of the equation by which Shares are redeemable. The Exchange has no obligation or liability to owners of Shares in connection with the administration, marketing, or trading of Shares.

Without limiting any of the foregoing, in no event shall the Exchange have any liability for any lost profits or indirect, punitive, special, or consequential damages even if notified of the possibility thereof.

The Adviser and the Fund make no representation or warranty, express or implied, to the owners of Shares or any member of the public regarding the advisability of investing in securities generally or in the Fund particularly.
