SUMMARY INFORMATION

Defiance AI Hyperscale Leaders ETF - FUND SUMMARY

Investment Objective

The Defiance AI Hyperscale Leaders ETF seeks long term capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that 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⁽¹⁾ (expenses that you pay each year as a percentage of the value of your investment)
Management Fee	[ ]-
Distribution and Service (12b-1) Fees	None
Other Expenses⁽²⁾	0.00%
Total Annual Fund Operating Expenses	[ ]-

⁽¹⁾

Under the Fund’s investment advisory agreement, in exchange for a single unitary management fee from the Fund, the Fund’s adviser has agreed to pay all expenses incurred by the Fund, except for its advisory fee, 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, distribution fees and expenses paid by the Fund under any distribution plan adopted pursuant to Rule 12b-1 under the Investment Company Act of 1940 (the “1940 Act”), and litigation expenses, and other non-routine or extraordinary expenses.

⁽²⁾	Estimated for the current year.

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 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. The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$[ ]	$[ ]

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 total annual fund operating expenses or in the expense example above, affect the Fund’s performance. Because the Fund is newly organized, portfolio turnover information is not yet available.

Principal Investment Strategies

Overview

The Fund is an actively managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective by directly or indirectly investing in U.S.-listed equity securities of companies that the Adviser believes are leaders in enabling, developing, or benefiting from artificial intelligence (“AI”) by demonstrating strong scalability, positive revenue growth and profitability.

The Adviser seeks to identify companies that, in the Adviser’s view, are well positioned to benefit from the increasing adoption and deployment of AI technologies including companies that own and operate global AI compute infrastructure, including cloud platforms, emerging AI-native cloud providers, data center expansion, AI model deployment infrastructure, development of AI models, development of the AI ecosystem, semiconductors, AI-related software platforms, or technologies that support AI-driven applications.

Under normal market conditions, the Fund will invest at least 80% of its net assets (plus borrowings for investment purposes) in a combination of equity securities issued by AI Hyperscale Leaders (defined below) or derivatives instruments that provide exposure to those securities. For purposes of compliance with this investment policy, derivative instruments will be valued at their notional value.

The Fund defines “AI Hyperscale Leaders,” as companies that meet the following criteria:

AI Business Activity. Companies that meet one or more of the following:

Derive at least 50% of their revenues from AI compute infrastructure, cloud platforms, emerging AI-native cloud providers, data center expansion, AI model deployment infrastructure, development of AI models, development of the AI ecosystem, semiconductors, AI-related software platforms, or technologies that support AI-driven applications;

Allocate at least 50% of their assets or capital expenditures to AI compute infrastructure, cloud platforms, emerging AI-native cloud providers, data center expansion, AI model deployment infrastructure, development of AI models, development of the AI ecosystem, semiconductors, AI-related software platforms, or technologies that support AI-driven applications; or

Incur at least 50% of their research and development expenditures related to AI compute infrastructure, cloud platforms, emerging AI-native cloud providers, data center expansion, AI model deployment infrastructure, development of AI models, development of the AI ecosystem, semiconductors, AI-related software platforms, or technologies that support AI-driven applications.

Scalability. Companies with a positive ratio of revenue growth rate to operating expense growth rate. This means that the company’s revenue must be growing at a faster rate than its operating expenses, generally indicating efficiency in scaling operations.

Revenue Growth: Companies with year-over-year positive annual revenue growth rate based on data from the most recently reported fiscal year end.

Profitability: Companies must have a positive gross profit margin (the percentage of revenue remaining after deducting the cost of goods sold) based on data from the most recently reported fiscal quarter.

Direct/Synthetic Investments: The Fund will invest in the equity securities of AI Hyperscale Leaders, including common stocks, business trust shares, American Depositary Receipts (“ADRs”), and other equity interests, either directly or indirectly (synthetically). When investing indirectly the Fund will invest in derivative instruments, including options, swaps and futures contracts to gain economic exposure to the equity securities of AI Hyperscale Leaders when the portfolio managers believe doing so is in the best interest of the Fund based on relevant market factors.

When making buys and sell decisions for the Fund, the Adviser also will also consider additional measures of profitability, financial discipline, and growth metrics to construct a portfolio of companies it believes are well-positioned for continued expansion and competitive advantage in AI-driven markets.

The Fund will typically invest in a portfolio of approximately 10 to 50 companies. The Adviser will determine the portfolio weight of each company, in its discretion, after considering factors, including market capitalization, liquidity, and the Adviser’s assessment of each company’s growth potential, AI exposure, and risk profile.

Fund Attributes

The Fund is classified as “non-diversified,” which means it may invest a greater percentage of its assets in a smaller number of issuers than a diversified fund.

The Fund will be concentrated in companies in the artificial intelligence (AI) industry and in industries that develop, deploy or operate AI-related technologies and services.

Principal Investment Risks

The principal risks of investing in the Fund are summarized below. 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 (“NAV”) per share, trading price, yield, total return, and/or ability to meet its objective. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Funds—Principal Risks of Investing in the Funds.”

An investment in the Fund entails risk. The Fund may not achieve its investment objective and there is a risk that you could lose all of your money invested in the Fund. The Fund is not a complete investment program. It is important that investors closely review all of the risks listed below and understand them before making an investment in the Fund.

Equity Market Risk. 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 specific issuers. 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, such as those held by the Fund, 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.

Concentration Risk. The Fund’s investment exposure will be concentrated in (or substantially exposed to) the same industry or group of industries to the extent the Index is so concentrated. In such event, the value of Shares may rise and fall more than the value of shares that invest in securities of companies in a broader range of industries.

Artificial Intelligence (AI) Investing Risks. The Fund invests indirectly in companies that derive a substantial portion of their revenues or operating activities from AI-related technologies and services and, as a result, is subject to risks associated with companies in the AI industry and in industries that develop, deploy, or operate AI-related technologies and services, which may cause the Fund’s investments to be more volatile than those of more diversified funds. Companies engaged in AI and big data typically face intense competition and potentially rapid product obsolescence. These companies are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. There can be no assurance these companies will be able to successfully protect their intellectual property to prevent the misappropriation of their technology, or that competitors will not develop technology that is substantially similar or superior to such companies’ technology. AI and big data companies are potential targets for cyberattacks, which can have a materially adverse impact on the performance of these companies. In addition, AI technology could face increasing regulatory scrutiny in the future, which may limit the development of this technology and impede the growth of companies that develop and/or utilize this technology. Similarly, the collection of data from consumers and other sources could face increased scrutiny as regulators consider how the data is collected, stored, safeguarded and used. AI and big data companies may face regulatory fines and penalties, including potential forced break-ups, that could hinder the ability of the companies to operate on an ongoing basis. The customers and/or suppliers of AI and big data companies may be concentrated in a particular country, region or industry. Any adverse event affecting one of these countries, regions or industries could have a negative impact on AI and big data companies. Country, government, and/or region-specific regulations or restrictions could have an impact on AI and big data companies. The markets and use cases for products with AI capabilities have been rapidly evolving, are difficult to predict, and may impact demand for products, sales cycles, ability to forecast results from sales of these products, and the preferences of customers and potential customers. The significant investments Target Portfolio companies have made to develop products and software to address what it believes will be increasing demand for AI capabilities may be insufficient, and the company may face significant hurdles, including whether demand will materialize, whether third-party software providers will develop functionality that allows their software to utilize the AI capabilities of Target Portfolio companies’ products, and whether such companies will be successful in developing, pricing, and packaging products that can compete with offerings by competitors. Additionally, use of AI technology in general may subject us to reputational, financial, legal, or regulatory risks.

Semiconductor Companies Risks. Competitive pressures may have a significant effect on the financial condition of semiconductor companies and, as product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Reduced demand for end-user products, under-utilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor sector. Semiconductor companies typically face high capital costs and may be heavily dependent on intellectual property rights. The semiconductor sector is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. The stock prices of companies in the semiconductor sector have been and likely will continue to be extremely volatile.

Software Companies Risk. The software companies can be significantly affected by intense competition, aggressive pricing, technological innovations, and product obsolescence. Companies in the software industry are subject to significant competitive pressures, such as aggressive pricing, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in this industry, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many software companies have limited operating histories. Prices of these companies’ securities historically have been more volatile than other securities, especially over the short term.

Technology Companies Risk. Market or economic factors impacting technology companies and companies that rely heavily on technological advances could have a major effect on the value of the Fund’s investments. The value of stocks of 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. 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.

Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities (see Foreign Securities Risk below) and certain additional risks. Depositary receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares.

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

ETF Risks

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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.

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, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the 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. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. 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. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Foreign Securities Risk. [The Fund will not invest directly in foreign securities but may gain exposure to foreign issuers indirectly through exchange-listed ADRs (see Depositary Receipt Risk above)]. Investments in securities or other instruments of non-U.S. issuers, even when made through ADRs, involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Exposure to issuers in emerging markets can have more risk than investing in developed foreign markets. Governments of developing and emerging market countries may be more unstable as compared to more developed countries. 

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.

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the underlying asset and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

Futures Contracts. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for the Fund to make daily cash payments to maintain its required margin, particularly at times when the Fund may have insufficient cash; and (vi) unfavorable execution prices from rapid selling.

Swap Agreements. Swap agreements involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund. Additionally, certain unexpected market events or significant adverse market movements could result in the Fund not holding enough assets to be able to meet its obligations under the agreement. Such occurrences may negatively impact the Fund’s ability to implement its principal investment strategies and could result in losses to the Fund.

New Fund Risk. The Fund is a recently organized management investment company with no operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund, Adviser, and Sub-Advisers seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

U.S. Government and U.S. Agency Obligations Risk. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

Performance

Performance information for the Fund is not included because the Fund has not completed a full calendar year of operations as of the date of this Prospectus. When such information is included, this section will provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance history from year to year and showing how the Fund’s average annual total returns compare with those of the Index and a broad measure of market performance. Although past performance of the Fund is no guarantee of how it will perform in the future, historical performance may give you some indication of the risks of investing in the Fund. Updated performance information will be available on the Fund’s website at [www.defianceetfs.com].

Management

Investment Adviser: Tidal Investments LLC (the “Adviser”) serves as investment adviser to the Fund.

Portfolio Managers:

The following individuals are jointly and primarily responsible for the day-to-day management of the Fund.

Qiao Duan, CFA, Portfolio Manager for the Adviser, has been a portfolio manager of the Fund since its inception in 2025.

Stephen Foy, Portfolio Manager for the Adviser, has been a portfolio manager of the Fund since its inception in 2025.

CFA^®is a registered trademark owned by the CFA Institute.]

Purchase and Sale of Shares

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

Shares are listed on a national securities exchange, such as 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).

An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (the “bid” price) and the lowest price a seller is willing to accept for Shares (the “ask” price) when buying or selling Shares in the secondary market. This difference in bid and ask prices is often referred to as the “bid-ask spread.”

When available, information regarding the Fund’s NAV, market price, how often Shares traded on the Exchange at a premium or discount, and bid-ask spreads can be found 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 an 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

Investment Objective

The Defiance AI Hyperscale Leaders ETF seeks long term capital appreciation.

An investment objective is fundamental if it cannot be changed without the consent of the holders of a majority of the outstanding Shares. The Fund’s investment objective has not been adopted as a fundamental investment policy and therefore may be changed without the consent of the Fund’s shareholders upon approval by the Board of Trustees (the “Board”) of Tidal Trust IV (the “Trust”) and at least 60 days’ written notice to shareholders.

Additional Information About the Fund’s Principal Investment Strategies

The following information is in addition to, and should be read along with, the description of the Fund’s principal investment strategies in the section titled Fund Summary-Principal Investment Strategies above.

80% Policy

The Fund’s “80%” policy is non-fundamental and can be changed without shareholder approval. However, Fund shareholders would be given at least 60 days’ notice prior to any such change.

Manager of Managers Structure

Although the Fund is not currently sub-advised, the Fund and the Adviser have received exemptive relief from the SEC permitting the Adviser (subject to certain conditions and the approval of the Board) to change or select new sub-advisers without obtaining shareholder approval. The relief 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. The Adviser has the ultimate responsibility, subject to oversight by the Board, to oversee a sub-adviser and recommend their hiring, termination and replacement. The exemptive relief applies to sub-advisers that are either wholly owned by the Adviser or its parent company, as well as to unaffiliated sub-advisers, including those whose affiliation arises solely from their sub-advisory relationship.

Principal Risks of Investing in the Fund

There can be no assurance that the Fund will achieve its investment objective. The following information is in addition to, and should be read along with, the description of the Fund’s principal investment risks in the section titled “Fund Summary— Principal Investment Risks” above. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.

[Artificial Intelligence (AI) Investing Risks. The Fund invests indirectly in companies that derive a substantial portion of their revenues or operating activities from AI-related technologies and services and, as a result, is subject to risks associated with companies in the AI industry and in industries that develop, deploy, or operate AI-related technologies and services, which may cause the Fund’s investments to be more volatile than those of more diversified funds. Companies engaged in AI and big data typically face intense competition and potentially rapid product obsolescence. These companies are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. There can be no assurance these companies will be able to successfully protect their intellectual property to prevent the misappropriation of their technology, or that competitors will not develop technology that is substantially similar or superior to such companies’ technology. AI and big data companies are potential targets for cyberattacks, which can have a materially adverse impact on the performance of these companies. In addition, AI technology could face increasing regulatory scrutiny in the future, which may limit the development of this technology and impede the growth of companies that develop and/or utilize this technology. Similarly, the collection of data from consumers and other sources could face increased scrutiny as regulators consider how the data is collected, stored, safeguarded and used. AI and big data companies may face regulatory fines and penalties, including potential forced break-ups, that could hinder the ability of the companies to operate on an ongoing basis. The customers and/or suppliers of AI and big data companies may be concentrated in a particular country, region or industry. Any adverse event affecting one of these countries, regions or industries could have a negative impact on AI and big data companies. Country, government, and/or region-specific regulations or restrictions could have an impact on AI and big data companies. The markets and use cases for products with AI capabilities have been rapidly evolving, are difficult to predict, and may impact demand for products, sales cycles, ability to forecast results from sales of these products, and the preferences of customers and potential customers. The significant investments Target Portfolio companies have made to develop products and software to address what it believes will be increasing demand for AI capabilities may be insufficient, and the company may face significant hurdles, including whether demand will materialize, whether third-party software providers will develop functionality that allows their software to utilize the AI capabilities of Target Portfolio companies’ products, and whether such companies will be successful in developing, pricing, and packaging products that can compete with offerings by competitors. Additionally, use of AI technology in general may subject us to reputational, financial, legal, or regulatory risks.

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in the underlying reference asset(s). Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

Futures Contracts. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for the Fund to make daily cash payments to maintain its required margin, particularly at times when the Fund may have insufficient cash; and (vi) unfavorable execution prices from rapid selling.

Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” If the market for these contracts is in “contango,” meaning that the prices of futures contracts in the nearer months are lower than the price of contracts in the distant months, the sale of the near-term month contract would be at a lower price than the longer-term contract, resulting in a cost to “roll” the futures contract. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract. Because the margin requirement for futures contracts is less than the value of the assets underlying the futures contract, futures trading involves a degree of leverage. As a result, a relatively small price movement in a futures contract may result in immediate and substantial loss, as well as gain, to the Fund.

Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests is substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the under-lying instrument. There may at times be an imperfect correlation between the movement in the values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund intends to continuously maintain indirect exposure to the underlying instrument through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses.

Swap Agreements. Swap agreements involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund. Additionally, certain unexpected market events or significant adverse market movements could result in the Fund not holding enough assets to be able to meet its obligations under the agreement. Such occurrences may negatively impact the Fund’s ability to implement its principal investment strategies and could result in losses to the Fund. The risk of loss to the Fund for swap transactions that are entered into on a net basis depends on which party is obligated to pay the net amount to the other party. If the counterparty is obligated to pay the net amount to the Fund, the risk of loss to the Fund is loss of the entire amount that the Fund is entitled to receive. If the Fund is obligated to pay the net amount, the Fund’s risk of loss is generally limited to that net amount. If the swap agreement involves the exchange of the entire principal value of a security, the entire principal value of that security is subject to the risk that the other party to the swap will default on its contractual delivery obligations. In addition, the Fund’s risk of loss also includes any margin at risk in the event of default by the counterparty (in an uncleared swap) or the central counterparty or FCM (in a cleared swap), plus any transaction costs.

Economic and Market Risk. The Fund is subject to the risk that the securities markets will move down, sometimes rapidly and unpredictably, based on overall economic conditions and other factors, which may negatively affect the Fund’s performance. Factors that affect markets in general, including geopolitical, regulatory, market and economic developments and other developments that impact specific economic sectors, industries, companies and segments of the market, could adversely impact the Fund’s investments and lead to a decline in the value of your investment in the Fund. Geopolitical and other events, including tensions, war, and open conflict between nations, such as between Russia and Ukraine, in the Middle East and in eastern Asia, could affect the economies of many countries including the United States. Trade disputes, pandemics, public health crises, natural disasters, cybersecurity incidents, and related events have led, and in the future may continue to lead, to instability in world economies and markets generally and reduced liquidity in equity, credit and fixed income markets, which may disrupt economies and markets and adversely affect the value of your investment. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets. In addition, policy changes by the U.S. government, the U.S. Federal Reserve and/or foreign governments, and political and economic changes within the U.S. and abroad, such as inflation, changes in interest rates, recessions, changes in the U.S. presidential administration and Congress, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, the threat of a federal government shutdown, threats not to increase the federal government’s debt limit which could result in a default on the government’s obligations, and the shutdown of certain financial institutions, may cause increased volatility in financial markets, affect investor and consumer confidence and adversely impact the broader financial markets and economy, perhaps suddenly and to a significant degree. Slowing global economic growth, the rise in protectionist trade policies, inflationary pressures, changes to some major international trade agreements, the imposition of tariffs, risks associated with trade agreements between countries and regions, including the U.S. and other foreign nations, political or economic dysfunction within some countries or regions, including the U.S., and dramatic changes in consumer sentiment and commodity and currency prices could affect the economies and markets of many nations, including the U.S., in ways that cannot necessarily be foreseen at the present time and may create significant market volatility. In 2022 the Federal Reserve and certain foreign central banks began to increase interest rates to address rising inflation. The Federal Reserve and certain foreign central banks subsequently started to lower interest rates in September 2024, though economic or other factors, such as inflation, could lead to the Federal Reserve stopping or reversing these changes. It is difficult to accurately predict the pace at which interest rates might change, the timing, frequency or magnitude of any such changes in interest rates, or when such changes might stop or again reverse course. Unexpected changes in interest rates could lead to significant market volatility or reduce liquidity in certain sectors of the market. Market disruptions have caused, and may continue to cause, broad changes in market value, negative public perceptions concerning these developments, and adverse investor sentiment or publicity. Changes in value may be temporary or may last for extended periods. Regulators in the U.S. have adopted a number of changes to regulations affecting markets and issuers, some of which apply to the Fund. Due to the broad scope of the regulations being adopted, certain of these changes, which may be revised or rescinded, could limit the Fund’s ability to pursue its investment strategies or make certain investments, may make it more costly for it to operate, or adversely impact performance.

ETF Risks

Costs of Buying or Selling Shares. Buying or selling Shares involves certain costs, including brokerage commissions, other charges imposed by brokers, and bid-ask spreads. The bid-ask spread represents the difference between the price at which an investor is willing to buy Shares and the price at which an investor is willing to sell Shares. The spread varies over time based on the Shares’ trading volume and market liquidity. 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. Due to the costs of buying or selling Shares, frequent trading of Shares may reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

Foreign Securities Risk. The Fund will not invest directly in foreign securities but may gain exposure to foreign issuers indirectly through exchange-listed ADRs (see Depositary Receipt Risk above). Investments in securities or other instruments of non-U.S. issuers, even when made through ADRs, involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Exposure to issuers in emerging markets can have more risk than investing in developed foreign markets. Governments of developing and emerging market countries may be more unstable as compared to more developed countries. 

Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses that may not produce the desired result. There can be no guarantee that the Fund will meet its investment objective.

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.

PORTFOLIO HOLDINGS INFORMATION

The Fund’s SAI provides additional information about each Portfolio Manager’s compensation structure, other accounts that each Portfolio Manager manages, and each Portfolio Manager’s ownership of Shares.

Fund Sponsor

The Adviser has entered into a fund sponsorship agreement with Defiance ETFs, LLC (“Defiance”) pursuant to which Defiance is a sponsor to the Fund. Under this arrangement, Defiance has agreed to provide financial support (as described below) to the Fund. Every month, unitary management fees for the Fund are calculated and paid to the Adviser, and the Adviser retains a portion of the unitary management fees from the Fund.

In return for its financial support for the Fund, the Adviser has agreed to pay Defiance a portion of any remaining profits generated by unitary management fee the Fund. If the amount of the unitary management fees for the Fund exceeds the Fund’s operating expenses and the Adviser-retained amount, that excess amount is considered “remaining profit.” In that case, the Adviser will pay a portion of the remaining profits to Defiance.

If the amount of the unitary management fee for the Fund is less than the Fund’s operating expenses and the Adviser-retained amount, Defiance is obligated to reimburse the Adviser for a portion of the shortfall.

HOW TO BUY AND SELL SHARES

The Fund issues and redeems Shares only in Creation Units at the NAV per share next determined after receipt of an order from an AP. 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.

In order to purchase Creation Units of a Fund, an AP must generally deposit a designated portfolio of equity securities (the “Deposit Securities”) and/or a designated amount of U.S. cash. Purchases and redemptions of Creation Units primarily with cash, rather than through in-kind delivery of portfolio securities, may cause the Funds to incur certain costs. These costs could include brokerage costs or taxable gains or losses that it might not have incurred if it had made redemption in-kind. These costs could be imposed on a Fund, and thus decrease the Fund’s NAV, to the extent that the costs are not offset by a transaction fee payable by an AP.

Most investors buy and sell Shares in secondary market transactions through brokers. Individual 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 the 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 regular business. The NAV for the Fund 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. If such information is not available for a security or other asset held by the Fund or is determined to be unreliable, the security or other asset will be valued at fair value estimates under guidelines established by the Adviser (as described below).

Debt securities are valued by using an evaluated mean of the bid and asked prices provided by independent pricing agents. The independent pricing agents may employ methodologies that utilize actual market transactions (if the security is actively traded), broker dealer supplied valuations, or other methodologies designed to identify the market value for such securities. In arriving at valuations, such methodologies generally consider factors such as security prices, yields, maturities, call features, ratings and developments relating to specific securities.

Additionally, the Fund values swap agreements based on the nature of the underlying reference asset or index. The Fund may use the closing price of the underlying reference asset, as provided by independent pricing services, or evaluated prices generated by pricing vendors’ models. The Fund values exchange-traded options at the composite mean price, calculated as the average of the highest bid and lowest ask prices across the exchanges on which the option is principally traded. Futures contracts are priced by an approved independent pricing service. Futures contracts are valued at the settlement price on the exchange on which they are principally traded.

Generally, trading in non-U.S. securities and money market instruments is substantially completed each day at various times prior to the close of regular trading hours of the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

Fair Value Pricing

The Board has designated the Adviser as the “valuation designee” for the Fund under Rule 2a-5 of the 1940 Act, subject to its oversight. The Adviser has adopted procedures and methodologies, which have been approved by the Board, to fair value Fund investments whose market prices are not readily available or are deemed to be unreliable. For example, such circumstances may arise when: (i) an investment has been delisted or has had its trading halted or suspended; (ii) an investment’s primary pricing source is unable or unwilling to provide a price; (iii) an investment’s primary trading market is closed during regular market hours; or (iv) an investment’s value is materially affected by events occurring after the close of the investment’s primary trading market. Generally, when fair valuing an investment, 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 investment, general and/or specific market conditions, and the specific facts giving rise to the need to fair value the investment. Fair value determinations are made in good faith and in accordance with the fair value methodologies included in the Adviser adopted valuation procedures. The Adviser will fair value Fund investments whose market prices are not “readily available” or are deemed to be unreliable. Due to the subjective and variable nature of fair value pricing, there can be no assurance that the Adviser will be able to obtain the fair value assigned to the investment upon the sale of such investment.

Investments by Other Registered Investment Companies in the Fund

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. 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 of rules under the 1940 Act, including that such investment companies enter into an agreement with the Fund.

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.

DIVIDENDS, DISTRIBUTIONS, AND TAXES

Dividends and Distributions

The Fund intends to pay out dividends and interest income, if any, annually, and distribute any net realized capital gains to its shareholders at least annually. The Fund will declare and pay income and capital gain distributions, if any, 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 some 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.

The Fund intends to qualify each year for treatment as a regulated investment company (a “RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”). If it 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 plan, 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 (institutional investors only).

The following general discussion of certain U.S. federal income tax consequences is based on provisions of the Code and the regulations issued thereunder as in effect on the date of this Prospectus. New legislation, as well as administrative changes or court decisions, may significantly change the conclusions expressed herein, and may have a retroactive effect with respect to the transactions contemplated herein.

Taxes on Distributions

For federal income tax purposes, distributions of net investment income are generally taxable to shareholders as ordinary income or qualified dividend income. Taxes on distributions of net 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 their 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 to shareholders. Distributions of short-term capital gain will generally be taxable to shareholders 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 certain 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 receives 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.

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

In addition to the federal income tax, certain individuals, trusts, and estates may be subject to a Net Investment Income (“NII”) tax of 3.8%. The NII tax is imposed on the lesser of: (i) a taxpayer’s investment income, net of deductions properly allocable to such income; or (ii) the amount by which such taxpayer’s modified adjusted gross income exceeds certain thresholds ($250,000 for married individuals filing jointly, $200,000 for unmarried individuals and $125,000 for married individuals filing separately). The Fund’s distributions are includable in a shareholder’s investment income for purposes of this NII tax. In addition, any capital gain realized by a shareholder upon a sale or redemption of Fund shares is includable in such shareholder’s investment income for purposes of this NII tax.

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 to you 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 to you 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. 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.

Under the Foreign Account Tax Compliance Act (“FATCA”), the Funds may be required to withhold a generally nonrefundable 30% tax on distributions of net investment income paid to (A) certain “foreign financial institutions” unless such foreign financial institution agrees to verify, monitor, and report to the Internal Revenue Service (“IRS”) the identity of certain of its account-holders, among other items (or unless such entity is otherwise deemed compliant under the terms of an intergovernmental agreement between the United States and the foreign financial institution’s country of residence), and (B) certain “non-financial foreign entities” unless such entity certifies to the Fund that it does not have any substantial U.S. owners or provides the name, address, and taxpayer identification number of each substantial U.S. owner, among other items. This FATCA withholding tax could also affect the Fund’s return on its investments in foreign securities or affect a shareholder’s return if the shareholder holds its Fund shares through a foreign intermediary. You are urged to consult your tax adviser regarding the application of this FATCA withholding tax to your investment in the Fund and the potential certification, compliance, due diligence, reporting, and withholding obligations to which you may become subject in order to avoid this withholding tax.

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 of the taxable distributions and sale or redemption 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 they are not subject to such withholding.

Taxes When Shares are Sold on the Exchange

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 are acquired, including through reinvestment of dividends, within a 61-day period beginning 30 days before and ending 30 days after the sale of substantially identical Shares.

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 their holdings) or on the basis that there has been no significant change in economic position. 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 Shares comprising the Creation Units have been held for more than one year and as a short-term capital gain or loss if such Shares have been held for one year or less.

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.

Foreign Investments by the Fund

Interest and other income received by the Fund with respect to foreign securities may give rise to withholding and other taxes imposed by foreign countries. Tax treaties or conventions between certain countries and the United States may reduce or eliminate such taxes. If, as of the close of a taxable year, more than 50% of the value of the Fund’s assets consists of certain foreign stock or securities, the Fund will be eligible to elect to pass through to investors the amount of certain qualifying foreign income and similar taxes paid by the Fund during that taxable year. This means that investors would be considered to have received as additional income their respective shares of such foreign taxes, but may be entitled to either a corresponding tax deduction in calculating taxable income, or, subject to certain limitations, a credit in calculating federal income tax. If the Fund does not so elect, the Fund will be entitled to claim a deduction for certain foreign taxes incurred by the Fund. The Fund (or its administrative agent) 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.

Taxes on Purchases and Redemptions of Creation Units

Important Tax Considerations When Purchasing Fund Shares

If you are investing through a taxable account, you should carefully consider the timing of your investment relative to a Fund’s distribution schedule. Purchasing Fund shares shortly before a distribution may increase your tax liability, a situation commonly referred to as “buying a dividend.”

When a Fund makes a distribution, its share price typically drops by an amount roughly equal to the distribution. As a hypothetical example, if you invest $5,000 to purchase 250 shares at $20 per share on December 15, and the Fund pays a $1 per share distribution on December 16, the share price would adjust to $19 (ignoring market fluctuations). Although your total investment value remains $5,000 (250 shares × $19 in share value plus 250 shares × $1 distribution), you would owe taxes on the $250 distribution, even if you reinvest the distribution rather than receiving it in cash.

Distributions are taxable to shareholders even if they are paid from income or gains realized by a Fund before you invested, and even if they were reflected in the purchase price of the shares. Consequently, you may incur taxes on income or gains that accrued before your investment, without corresponding benefit.

Unless you are investing through a tax-advantaged account, such as an IRA or an employer-sponsored retirement plan, you may wish to avoid purchasing Fund shares shortly before a distribution. You can minimize the potential tax impact by reviewing the relevant Fund’s distribution schedule prior to investing. When available, information about a Fund’s distribution schedule can be found on the Funds’ website at [www.defianceetfs.com].

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 foreign, 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

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

The Board has adopted a Distribution (Rule 12b-1) 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 to pay distribution fees for the sale and distribution of its Shares.

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 Fund assets on an ongoing basis, 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

When available, 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 of the Fund can be found 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 the 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.

The Agreement and Declaration of Trust (“Declaration of Trust”) provides a detailed process for the bringing of derivative or direct actions by shareholders in order to permit legitimate inquiries and claims while avoiding the time, expense, distraction, and other harm that can be caused to the Fund or its shareholders as a result of spurious shareholder demands and derivative actions. Prior to bringing a derivative action, a demand by three unrelated shareholders must first be made on the Fund’s Trustees. The Declaration of Trust details various information, certifications, undertakings and acknowledgments that must be included in the demand. Following receipt of the demand, the trustees have a period of 90 days, which may be extended by an additional 60 days, to consider the demand. If a majority of the Trustees who are considered independent for the purposes of considering the demand determine that maintaining the suit would not be in the best interests of the Fund, the Trustees are required to reject the demand and the complaining shareholders may not proceed with the derivative action unless the shareholders are able to sustain the burden of proof to a court that the decision of the Trustees not to pursue the requested action was not a good faith exercise of their business judgment on behalf of the Fund. The Declaration of Trust further provides that shareholders owning Shares representing no less than a majority of the Fund’s outstanding shares must join in bringing the derivative action. If a demand is rejected, the complaining shareholders will be responsible for the costs and expenses (including attorneys’ fees) incurred by the Fund in connection with the consideration of the demand, if a court determines that the demand was made without reasonable cause or for an improper purpose. If a derivative action is brought in violation of the Declaration of Trust, the shareholders bringing the action may be responsible for the Fund’s costs, including attorneys’ fees, if a court determines that the action was brought without reasonable cause or for an improper purpose. The Declaration of Trust provides that no shareholder may bring a direct action claiming injury as a shareholder of the Trust, or any Fund, where the matters alleged (if true) would give rise to a claim by the Trust or by the Trust on behalf of the Fund, unless the shareholder has suffered an injury distinct from that suffered by the shareholders of the Trust, or the Fund, generally. Under the Declaration of Trust, a shareholder bringing a direct claim must be a shareholder of the Fund with respect to which the direct action is brought at the time of the injury complained of or have acquired the shares afterwards by operation of law from a person who was a shareholder at that time. The Declaration of Trust further provides that the Fund shall be responsible for payment of attorneys’ fees and legal expenses incurred by a complaining shareholder only if required by law, and any attorneys’ fees that the Fund is obligated to pay shall be calculated using reasonable hourly rates. These provisions do not apply to claims brought under the federal securities laws.

The Declaration of Trust also requires that actions by shareholders against the Fund be brought exclusively in a federal or state court located within the State of Delaware. This provision will not apply to claims brought under the federal securities laws. Limiting shareholders’ ability to bring actions only in courts located in Delaware may cause shareholders economic hardship to litigate the action in those courts, including paying for travel expenses of witnesses and counsel, requiring retaining local counsel, and may limit shareholders’ ability to bring a claim in a judicial forum that shareholders find favorable for disputes, which may discourage such actions.
