SUMMARY INFORMATION

Defiance KSM TipRanks Analyst ETF - FUND SUMMARY

Investment Objective

The Defiance KSM TipRanks Analyst ETF (the “Fund”) seeks to track the performance, before fees and expenses, of the TipRanks US Momentum Analysts iNDEX (the “Index”).

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.

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 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:

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 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 exchange-traded fund (“ETF”) that uses a passive management (or indexing) approach to track the performance, before fees and expenses, of the Index. The Index tracks, subject to the Index rules described below, the performance of 50 U.S. exchange-listed companies evidencing high positive price momentum. Price momentum refers to the financial concept that an asset’s recent price performance (up or down) is likely to continue. The Index is calculated, administered, and disseminated by VettaFi (“Index Provider”) and owned by TipRanks Ltd. (“Index Owner”).

The Index

The Index’s eligible universe includes U.S. exchange-listed companies, including American Depositary Receipts (“ADRs”) of foreign companies (“U.S. Listed Companies”).

Constituents are market cap-weighted with the following constraints:

To the extent the Index is concentrated in a particular sector or industry, the Fund is expected to be concentrated in that same sector or industry. As of December 31, 2025, issuers in the information technology sector represented a significant portion of the Index.

Components of the Index are reconstituted and rebalanced on a quarterly basis.

The Fund’s Investment Strategy

The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it generally will invest directly or indirectly in all of the Index components. However, the Fund may use a “representative sampling” strategy, meaning it may invest directly or indirectly in a sample of the securities in the Index whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Index as a whole, when the Adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).

The Fund is classified as “non-diversified” under the 1940 Act. As of December 31, 2025, the Index contained 51 constituents.

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 per share (“NAV”), trading price, yield, total return and/or ability to meet its investment 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 Fund - Principal Risks of Investing 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.

Sector and Industry Risk. To the extent the Fund invests more heavily in particular sectors or industries of the economy, its performance will be especially sensitive to developments that significantly affect those sectors and industries. The Fund may invest a significant portion of its assets in the following sectors and industries and, therefore, the performance of the Fund could be negatively impacted by events affecting each of these sectors and industries.

Foreign Securities Risk. Investments in securities or other instruments of non-U.S. issuers 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. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices.

ADRs Risk. ADRs involve risks similar to those associated with investments in foreign securities and give rise to certain additional risks. ADRs 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 ADRs as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the ADRs may not provide a return that corresponds precisely with that of the Underlying Shares. Investment in ADRs may be less liquid than the Underlying Shares in their primary trading market.

ETF Risks

Economic and Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. 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.

Market Capitalization Risk

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 and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Momentum Risk. A momentum style of investing may emphasize investing in securities that have had better recent performance compared to other securities. Securities exhibiting marked recent outperformance may be more volatile than securities across the broader market, and momentum may be an indicator that a security’s price is peaking. Momentum can turn quickly and cause significant variation from other types of investments. To the extent it has exposure to momentum strategies, the Fund may experience significant losses if momentum stops, reverses or otherwise behaves differently than predicted.

Passive Investment Risk. The Fund is not actively managed and does not attempt to outperform the Index or take defensive positions in declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to the Index.

Third Party Data Risk. The composition of the Index, and consequently the Fund’s portfolio, is heavily dependent on information and data calculated and published by an independent third party calculation agent (“Third Party Data”). When Third Party Data proves to be incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities from the Index that would have been excluded or included had the Third Party Data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can also be expected to reflect the errors.

Tracking Error Risk. As with all index funds, the performance of the Fund and the Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in Index components at all times or may hold securities not included in the Index.

Underlying Index Risk. Neither the Fund’s investment adviser nor the Index Provider or Index Owner is able to guarantee the continuous availability or timeliness of the production of the Index. The calculation and dissemination of the Index values may be delayed if the information technology or other facilities of the Index Provider, Index Owner, data providers and/or relevant stock exchange malfunction for any reason. A significant delay may cause trading in shares of the Fund to be suspended. Errors in Index data, computation and/or the construction in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider, Index Owner, or other applicable party for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

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 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, a Tidal Financial Group company, 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 2026.

Andy Hicks, Portfolio Manager for the Adviser, has been a portfolio manager of the Fund since its inception in 2026.

Purchase and Sale of Shares

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 (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 to shareholders 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

Investment Objective

The Fund seeks to track the performance, before fees and expenses, of the Index.

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 II (the “Trust”) and 60 days’ written notice to shareholders.

Principal Investment Strategies

TipRanks US Momentum Analysts iNDEX

The Index is calculated, administered, and disseminated by VettaFi and owned by TipRanks Ltd. The Adviser was not involved in the creation of the Index, does not have any ownership in the Index and does not receive any fees associated with the use of the Index.

Rebalancing Schedule

The Index is reconstituted and rebalanced on a quarterly basis as of the close of business of the third Friday in March, June, September, and December.

Manager of Managers Structure

While the Fund does not currently have a sub-adviser, 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 unaffiliated sub-advisers without obtaining shareholder approval. The relief also permits the Adviser to materially amend the terms of agreements with an unaffiliated sub-adviser (including an increase in the fee paid by the Adviser to the unaffiliated sub-adviser (and not paid by the Fund)) or to continue the employment of an unaffiliated 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 unaffiliated 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

The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with those of 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 NAV per share, trading price, yield, total return and/or ability to meet its investment objective. The following risks could affect the value of your performance in the Fund:

ADRs Risk. ADRs involve risks similar to those associated with investments in foreign securities and give rise to certain additional risks. ADRs 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 ADRs as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the ADRs may not provide a return that corresponds precisely with that of the Underlying Shares. Investment in ADRs may be less liquid than the Underlying Shares in their primary trading market.

Economic and Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. 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.

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. Equity securities 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.

ETF Risks

Foreign Securities Risk. Investments in securities or other instruments of non-U.S. issuers 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.

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.

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.

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.

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 and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Passive Investment Risk. The Fund is not actively managed and does not attempt to outperform its Index or take defensive positions in declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index. The returns from the types of securities in which the Fund invests may underperform returns from other securities markets or different asset classes. This may cause the Fund to underperform other investment vehicles that invest in different asset classes. Different types of securities (for example, fixed-income securities) tend to go through cycles of doing better – or worse – than the general securities markets. In the past, these periods have lasted for as long as several years.

Sector and Industry Risk. To the extent the Fund invests more heavily in particular sectors or industries of the economy, its performance will be especially sensitive to developments that significantly affect those sectors and industries. The Fund may invest a significant portion of its assets in the following sectors and industries and, therefore, the performance of the Fund could be negatively impacted by events affecting each of these sectors and industries.

The calculation and dissemination of the Index values may be delayed if the information technology or other facilities of the Index Provider, Index Owner, data providers and/or relevant stock exchange malfunction for any reason.

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 the unitary management fee. If the amount of the unitary management fees 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 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 the 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 Fund 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 the 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. 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 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).

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. 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 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 an SEC exemptive rule 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 RIC under the IRC. 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 Fund 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.

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 the 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 the 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 the 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 Fund’s distribution schedule prior to investing. When available, information about the Fund’s distribution schedule can be found on the Fund’s 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 Fund’s distributor, 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, 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 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 Third Amended and Restated 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.
