SUMMARY INFORMATION

DEFIANCE LONG PURE QUANTUM ETF – FUND SUMMARY

Investment Objective

The Defiance Long Pure Quantum ETF (the “Fund”) 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	1.29	%
Distribution and Service (12b-1) Fees	None
Other Expenses⁽²⁾	0.00	%
Total Annual Fund Operating Expenses	1.29	%

⁽¹⁾	The Fund’s investment adviser, Tidal Investments LLC (the “Adviser”), a Tidal Financial Group company, will pay all expenses incurred by the Fund (except for advisory fees ) excluding interest charges on any borrowings made for investment purposes, 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, as amended (the “1940 Act”), and litigation expenses and other non-routine or extraordinary expenses.

⁽²⁾	Based on estimated amounts for the current fiscal year.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then 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
$131	$409

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 actively managed exchange-traded fund (“ETF”) that seeks long term capital appreciation by investing, directly or indirectly, in a portfolio of equity securities of “Pure Quantum Companies” defined as companies with at least 50% of their (i) annual revenue derived from, or (ii) operating activity engaged in, the development of quantum computing or machine learning. This includes, but is not limited to, companies engaged in:

●

The development of quantum hardware and software solutions;

●

Advancing communication systems leveraging quantum principles;

●

Innovating technologies enabling quantum and traditional computational interactions;

●

Producing enabling components, such as quantum sensors or advanced quantum materials; or

●

The development of machine learning technology (i.e., technology that seeks to enable computer systems to learn from data and improve their performance on specific tasks without explicit programming).

The term “quantum computing” refers to a type of computing that uses the principles of physics involving subatomic particles to process information faster and in more flexible ways than traditional computers. In traditional computing, a bit is limited to storing only a zero or a one, while a subatomic particle can store and process an infinite number of values at the same time, allowing it to solve large and complex problems much faster. By taking advantage of quantum properties like superposition (the ability of a quantum system to exist in multiple states at once) and entanglement (a connection between particles where the state of one instantly influences the state of another, even at a distance), quantum computers may lead to progress in a wide range of fields, including data security, scientific research, advanced manufacturing, and next-generation (“NextGen”) technologies (i.e., significantly improved or radically different versions of existing technologies, or new innovations that surpass capabilities of existing technologies).

Portfolio Selection

The Adviser employs a thematic and qualitative approach to identify and select a focused portfolio of generally between [5 and 10] companies aligned with the Fund’s quantum computing investment theme. The selection process emphasizes companies that demonstrate meaningful participation in the quantum computing technologies. Subject to the Fund’s 80% policy, if the Adviser determines there are insufficient Pure Quantum Companies, the Fund may invest in “secondary technology companies,” which are companies that develop, support, or are involved in the application of quantum computing. The companies in which the Fund invests are primarily U.S. large-capitalization companies that are listed on U.S. exchanges, including American Depositary Receipts (“ADRs”) of foreign companies.

The Adviser evaluates companies using a combination of thematic criteria, including:

●

Core Quantum Activities: Companies must identify quantum computing as a primary operational focus, demonstrated through stated objectives, product development efforts, or industry collaborations.

●

Industry Leadership: Emphasis is placed on companies recognized for innovation, ownership of significant patents, or participation in prominent quantum computing research and development initiatives.

●

Emerging Potential: Priority is given to companies achieving substantial advancements or demonstrating momentum in quantum computing applications, reflecting their potential for a growing impact within the industry.

●

Secondary Technology Companies: If there are insufficient pure quantum computing companies that meet the criteria, additional technology firms involved in the development, support, or application of quantum computing may be included as secondary selections.

Based on a proprietary evaluation framework, the Adviser constructs the Fund’s portfolio with generally between [5 and 10 holdings]. The number of Fund portfolio holdings may be influenced by the availability of eligible pure quantum companies and the suitability of secondary selections. The Fund’s portfolio will generally be equally-weighted across its holdings. The portfolio will be rebalanced as additional holdings are added or existing positions exited. The Adviser may make adjustments to portfolio weightings to account for liquidity constraints or market conditions, or to mitigate exposure to securities exhibiting extreme volatility, high correlations, or other company-specific characteristics that could disproportionately impact the Fund’s performance.

To maintain alignment with advancements in quantum computing technologies, shifts in company focus, and emerging opportunities, the Adviser will, at least quarterly, either reconfirm the constitution of portfolio holdings or establish a newly-constituted portfolio of different Pure Quantum Company and any “secondary technology company” securities (as described above).

The Adviser may, at its discretion, make adjustments to the portfolio at any time, to add or remove securities based on developments deemed material by the Adviser, including companies making significant breakthroughs, announcing material developments, or benefiting from advancements in the quantum sector.

Direct/Synthetic Investments

The Fund will invest in equity securities either directly or indirectly (synthetically) using options and swaps (as described below). The Fund will generally invest indirectly to satisfy applicable tax requirements for regulated investment companies.

The Fund may utilize listed options to achieve synthetic exposure to the Fund’s portfolio securities. The Fund primarily employs short-dated (a month or less) in-the-money call options (options with strike prices below the current market price of the underlying securities, offering immediate intrinsic value). These options allow the Fund to synthetically replicate the performance of underlying securities without direct ownership. The Fund may also utilize other option strategies to achieve similar synthetic exposure, including purchasing call options and selling put options with identical strike prices. These derivatives strategies enable the Fund to respond flexibly to market conditions, liquidity constraints, or other factors that may affect the availability or pricing of swap agreements. For additional details about the Fund’s use of options, please refer to the section of the Prospectus entitled “Additional Information About the Fund.”

In addition to options, the Fund may enter into swap agreements with financial institutions. These swap agreements are designed to synthetically replicate the performance of the securities in the Fund’s portfolio. The agreements will have specified durations, which will typically coincide with the Fund’s scheduled reconstitutions, but may range from one day to more than a year. Through each swap agreement, the Fund and the financial institution will agree to exchange the return (or differentials in rates of return) based on the performance of a particular security’s share price. The gross return (meaning the return before deducting any fees or expenses) to be exchanged or “swapped” between the parties is calculated with respect to a “notional amount”—a predetermined dollar value representing the underlying security that the Fund seeks to replicate synthetically. For additional details about the Fund’s use of swaps, please refer to the section of the Prospectus entitled “Additional Information About the Fund.”

Collateral

In addition, the Fund will hold cash and/or short-term U.S. Treasury securities or other short-term liquid instruments as collateral for the Fund’s derivatives transactions.

Fund Attributes

The Fund is classified as “non-diversified” under the 1940 Act. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus borrowings for investment purposes, in the securities of Pure Quantum Companies or derivative 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 will be concentrated in the quantum computing industry or group of industries.

There is no guarantee that the Fund’s investment strategy will be properly implemented, and an investor may lose some or all of its investment.

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 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.”

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.

Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.

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.

Quantum Computing Industry Risk. The quantum computing industry may be significantly affected by intense competition, aggressive pricing dynamics, rapid technological advancements, and the risk of product obsolescence. Companies in this industry face substantial competitive pressures, including competition for market share, the entry of new participants, and short innovation cycles driven by accelerated technological developments. These factors may result in limited earnings potential, declining profit margins, or both. Companies in the quantum computing sector are also exposed to the risk that their technologies, products, or services may fail to gain acceptance by consumers or businesses or may become rapidly outdated due to evolving advancements. The success of many quantum computing companies depends heavily on patent protection and intellectual property rights, making the cost of obtaining (or failing to obtain) patent approvals, litigating patent disputes, and the potential loss of patent protection critical factors affecting profitability. The expiration or invalidation of key patents can intensify pricing pressures and materially reduce profitability. Additionally, many companies in this sector have limited operating histories, adding to the uncertainty of their financial stability and long-term viability. Securities of quantum computing companies have historically demonstrated higher volatility compared to broader markets, particularly over shorter time frames, reflecting the speculative nature of the industry and the risks inherent in pioneering emerging technologies.

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, leverage, imperfect correlations 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 imperfect correlation between the share price of the Target Portfolio 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.

The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy.

In addition, the Fund’s investments in derivatives are subject to the following risks:

Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.

If the Fund’s portfolio has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its investment objective, even if the Fund’s portfolio later reverses all or a portion of its movement.

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. The value of the options contracts in which the Fund invests is substantially influenced by the value of the securities underlying the options contracts. 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 as the underlying instrument. There may at times be an imperfect correlation between the movement in 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 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. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Fund’s portfolio moves against its options positions, potentially resulting in a complete loss of the premiums paid.

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.

Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. The use of options contracts introduces distinct risks, including heightened volatility. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

Concentration Risk. The Fund’s investments will be concentrated in the quantum computing industry or group of industries. As a result, 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.

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.

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s Share price and total return to be reduced and fluctuate more than other types of investments.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective.

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.

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

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.

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 “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

Liquidity Risk. In certain circumstances, such as the disruption of the orderly markets for the financial instruments in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the financial instruments in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, health crises, natural disasters, excessive volatility, new legislation, or regulatory changes inside or outside of the U.S. These situations may have an impact on the liquidity of the Fund’s own 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.

Liquidity Risk. Some securities held by the Fund may be difficult to sell or be illiquid, particularly during times of market turmoil. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses or realizing gains. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

Market Capitalization Risk.

●

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

●

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

Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions, if any, may decline.

Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. The Fund’s sub-adviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that the Fund will meet its investment objective.

Money Market Instrument Risk. The Fund may use a variety of money market instruments for cash management purposes, including money market funds, depositary accounts and repurchase agreements. Repurchase agreements are contracts in which a seller of securities agrees to buy the securities back at a specified time and price. Repurchase agreements may be subject to market and credit risk related to the collateral securing the repurchase agreement. Money market instruments may lose money.

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 Fund’s investment advisor 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. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. 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.

Tax Risk. In order to qualify for the favorable tax treatment generally available to regulated investment companies, the Fund must satisfy certain diversification and other requirements. In particular, the Fund generally may not acquire a security if, as a result of the acquisition, more than 50% of the value of the Fund’s assets would be invested in (a) issuers in which the Fund has, in each case, invested more than 5% of the Fund’s assets and (b) issuers more than 10% of whose outstanding voting securities are owned by the Fund. The application of these requirements to certain investments (including swaps) that may be entered into by the Fund is unclear. In addition, the application of these requirements to the Fund’s investment objective is not clear. If the Fund were to fail to qualify as a regulated investment company, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income.

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 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.

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

Christopher P. Mullen, Portfolio Manager for the Adviser, has been a portfolio manager of the Fund since its inception in 2025

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 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 investment objective of the Fund is to seek 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 the Fund’s investment objective 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 at least 60 days’ written notice to shareholders.

Shares of the Fund upon commencement of operations will be listed and traded on the Exchange, where the market prices for the Shares may be different from the intra-day value of the Shares disseminated by the Exchange and from their NAV. Unlike conventional mutual funds, Shares are not individually redeemable directly with the applicable Fund. Rather, the Fund issues and redeems Shares on a continuous basis at NAV only in large blocks of Shares called “Creation Units.” Creation Units of the Fund is issued and redeemed for cash. As a result, retail investors generally will not be able to purchase or redeem Shares directly from, or with, the Fund. Most retail investors will purchase or sell Shares in the secondary market through a broker.

There is no guarantee that the Fund’s investment strategy will be properly implemented, and an investor may lose some or all of their investment.

Principal Investment Strategies

The Fund has adopted a policy of investing, under normal circumstances, at least 80% of its net assets, plus borrowings for investment purposes, in the securities of Pure Quantum Companies or derivative instruments that provide exposure to those securities. 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. For purposes of compliance with this investment policy, derivative instruments will be valued at their notional value.

The Fund seeks to achieve its investment objective by investing, directly or indirectly, in a portfolio of equity securities of primarily Pure Quantum Companies (as defined above). The Fund will invest in equity securities either directly or indirectly (synthetically) using options and swaps. The Fund will generally invest indirectly to satisfy applicable tax requirements for regulated investment companies. Additional information regarding the options and swaps used to achieve indirect synthetic exposure to equity securities is set out below, supplementing the description of how the Fund achieves indirect synthetic exposure to equity securities, via options and swaps, in the Summary section of this Prospectus.

Additional Information About Options

Options Terminology

The Fund’s options contracts derivative instruments whose value are based on the share prices of one or more underlying securities (which are referred to as “Underlying Assets” for purposes of this discussion). These contracts give a Fund the right or obligation to buy or sell shares of the Underlying Assets on or before the expiration date at the specified strike price, depending on whether it is a call option or a put option, and whether the Fund is the buyer or seller of the contract.

●

In general, an option contract gives the purchaser of the option contract the right to purchase (for a call option) or sell (for a put option) the underlying asset (like shares of the Underlying Assets) at a specified price (the “strike price”).

●

If exercised, an option contract obligates the seller to deliver shares (for a sold or “short” call) or buy shares (for a sold or “short” put) of the underlying asset at a specified price (the “strike price”).

●

Options contracts must be exercised or traded to close within a specified time frame, or they can be left to expire.

●

A traditional covered options strategy is an investment strategy where an investor (the Fund) sells a call option on an underlying asset it owns.

●

A synthetic covered options strategy is similar to a traditional covered options strategy in that the investor sells a call option that is based on the share price of the underlying asset. However, in a synthetic covered options strategy, the investor (the Fund) does not own the underlying asset, but rather seeks to synthetically replicate 100% of the price movements of the underlying asset through the use of various investment instruments.

Options Strategies

1. Selling Calls

Strategy Overview: Selling calls involves writing call options on a security. This strategy profits if the security’s share price remains below the strike price.

Market Movement Scenarios:

Security Increases in Value: If the security’s share price rises above the strike price, the Fund will lose the difference between the security’s share price and strike price, offset by the premium received.

Security Remains the Same: If the security’s share price remains the same, the call option will expire worthless, and the Fund keeps the premium received as profit.

Security Decreases in Value: If the security’s share price decreases, the call option will expire worthless, and the Fund keeps the premium received as profit.

2. Selling Credit Spreads

Strategy Overview: Selling credit spreads involves writing a call option at one strike price and buying another call option at a higher strike price or writing a put option at one strike price and buying another put option at a lower strike price. This strategy limits the potential loss compared to selling an option outright by capping it at the difference between the strike prices minus the net premium received.

Market Movement Scenarios (Call Example):

Security Increases in Value: If the security’s share price rises above the higher strike price, the Fund’s loss is capped at the difference between the strike prices minus the net premium received. Between strikes the Fund loses the difference between the security’s share price and the lower strike.

Security Remains the Same: If the security’s share price remains the same, both options will expire worthless, and the Fund keeps the net premium received as profit.

Security Decreases in Value: If the security’s share price decreases, both options will expire worthless, and the Fund keeps the net premium received as profit.

Market Movement Scenarios (Put Example):

Security increases in Value: If the security’s share price increases, both options will expire worthless, and the Fund keeps the net premium received as profit.

Security Remains the Same: If the security’s share price remains the same, both options will expire worthless, and the Fund keeps the net premium received as profit.

Security decreases in Value: If the security’s share price decreases below the higher strike price, the Fund’s loss is capped at the difference between the strike prices minus the net premium received. Between strikes the Fund loses the difference between the security’s share price and the lower strike.

3. Selling Diagonal Call Spreads

Strategy Overview: Selling diagonal call spreads involves selling a call option with a nearer expiration date and buying a call option with a later expiration date at a different strike price. This strategy aims to benefit from the time decay (see below) of the nearer-term option. Time decay is the reduction in an option’s value as the time to its expiration date approaches. An option’s decay accelerates as its expiration date gets closer because there is less time for an investor to earn a profit from that option.

Market Movement Scenarios (at the max maturity date of the options):

Security Remains the Same: If the security’s share price remains the same, both options will expire worthless, and the Fund keeps the net premium received as profit.

Security Decreases in Value: If the security’s share price decreases, both options will expire worthless, and the Fund keeps the net premium received as profit.

4. Cash-Secured Put Selling

Strategy Overview: Cash-secured put selling involves selling put options while holding enough cash to buy the security at the strike price if assigned.

Market Movement Scenarios:

Security Increases in Value: If the security’s share price rises, the put option will expire worthless, and the Fund keeps the premium received.

Security Remains the Same: If the security’s share price remains the same, the put option will expire worthless, and the Fund keeps the premium received.

Security Decreases in Value: If the security’s share price decreases, the Fund may be assigned the security at the strike price, but the Fund effectively buys it at a lower net price due to the premium received.

5. Selling Calendar Call Spreads

Strategy Overview: Selling calendar call spreads involves selling a short-term option and buying a longer-term option at the same strike price. This strategy benefits when the underlying remains near the strike price but loses if the price moves significantly away (up or down).

Market Movement Scenarios (between the two maturity dates):

Security Increases in Value: If the security’s share price rises above the strike, the short-term option will be exercised at a loss, but the long-term option increases in value, limiting some losses.

Security Remains the Same (below the strike): If the security’s share price remains the same, the short-term option expires worthless, and the Fund profits from the time decay differential.

Security Decreases in Value: If the security’s share price decreases, the short-term option expires worthless, and the Fund profits from the time decay differential.

6. Selling Collars

Strategy Overview: Selling collars involves selling a call option and buying a put option to protect against significant price movements. The premium received from selling the call offsets the cost of buying the put, while limiting potential losses.

Market Movement Scenarios:

Security Increases in Value: If the security’s share price rises above the call strike price, the Fund loses the difference between the security’s share price and strike price.

Security Remains the Same: If the security’s share price remains the same, both options expire worthless, and the Fund keeps the premium received from the call option but offset by the premium paid on the put option.

Security Decreases in Value: If the security’s share price falls below the put strike price, the Fund gains the difference between the security’s share price and strike price.

Supplemental Options Strategy (Debit Spreads)

In concert with one or more the foregoing options strategies, the Fund may buy call or put spreads, known as debit spreads to which may be used strategically with the other options strategies to offset margin requirements. A Fund may “leg into” debit spreads by entering the spread in stages, starting with an initial position and later adding the second leg. For example, the Adviser may use debit spreads instead of covering a worthless call. In this case, a Fund would enter a call spread with a lower strike call, thereby increasing the Fund’s potential for gains while maintaining the cost efficiency of the position.

Exchange Traded (Listed) Options

The Fund purchases and sells varied combinations of call and put options contracts that are exchange-traded, and which are primarily exchange-traded FLEX options. FLEX options are customized options contracts that trade on an exchange but provide investors with the ability to customize key contract terms like strike price, style and expiration date while achieving price discovery in competitive, transparent auctions markets and avoiding the counterparty exposure of “over-the-counter” (“OTC”) options positions. Like traditional exchange-traded options, FLEX Options are guaranteed for settlement by the OCC, a market clearinghouse that guarantees performance by counterparties to certain derivatives contracts. The FLEX options in the Fund invests are all European style options (options that are exercisable only on the expiration date). As of the date of this Prospectus, FLEX options are listed on the Chicago Board Options Exchange. The Fund will use the market value of its derivatives holdings for the purpose of determining compliance with the 1940 Act and the rules promulgated thereunder. Since the options held by the Fund are exchange-traded, these will be valued on a mark-to-market basis. In the event market prices are not available, the Fund will use fair value pricing pursuant to the fair value procedures adopted by the Trust’s Board of Trustees.

Options Premiums – Income/Return of Capital

Although the Fund’s use of options is primarily intended to synthetically replicate gains or losses of an underlying security or securities, without holding such securities directly, the Fund will also generate premium income when selling options. Receipt of an option premium does not always represent income. Depending on whether the transaction as a whole results in a gain or loss, such amounts may be treated for accounting or tax purposes as income or as a return of capital (“ROC”). ROC represents a return of a shareholder’s own invested capital and does not reflect traditional income such as dividends or interest. A portion (sometimes a significant portion) of a Fund’s cash distributions may be classified as ROC, which generally refers to the portion of a distribution that represents a return of the original investment (principal) rather than income or profit. Accordingly, such distributions do not necessarily reflect traditional income or yield, and receipt of an option premium could ultimately result in a net loss on the transaction if offset by subsequent closing transactions, exercise or settlement.

Additional Information About Swaps

The Fund will enter into swap agreements with major financial institutions for a specified period ranging from one day to more than one year whereby the Fund and the global financial institution will agree to exchange the return earned or realized on one or more underlying equity securities. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount,” e.g., the return on or change in value of a particular dollar amount representing an underlying security. The Adviser periodically adjusts the Fund’s exposure to underlying securities consistent with the Fund’s investment objective. The impact of market movements affecting underlying securities determines whether the derivatives portfolio needs to be repositioned. If the market value of the underlying security or securities subject to a swap rises, the value of the Fund’s net assets should rise, meaning its exposure will typically need to be increased. Conversely, if the market value of the underlying security or securities subject to a swap falls, the value of the Fund’s net assets should fall, meaning its exposure will typically need to be reduced.

The time and manner in which the Fund rebalances its derivatives portfolio may vary at the sole discretion of the Adviser, depending upon market conditions and other circumstances. The Fund reviews its notional exposure under each of its swap agreements, which reflects the extent of the Fund’s total investment exposure under the swap, to seek to ensure that the Fund’s exposure is in-line with its stated investment objective. For each security underlying a swap, the gross returns to be exchanged are calculated with respect to the notional amount and the underlying security market value returns to which the swap is linked. Swaps are typically closed out on a net basis. Thus, while the notional amount reflects the Fund’s total investment exposure under the swap, the net amount is the Fund’s current obligations (or rights) under the swap. That is the amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. As a result, the Fund may be more or less exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective. To the extent that the Fund needs to “roll” its swap positions (i.e., enter into new swap positions with a later expiration date as the current positions approach expiration), it could be subjected to increased costs, which could negatively impact the Fund’s performance.

Collateral Investments

The Fund will hold assets to serve as collateral for the Fund’s derivatives transactions. For those collateral holdings, the Fund may invest in (1) U.S. Government securities, such as bills, notes and bonds issued by the U.S. Treasury; (2) money market funds; (3) short term bond exchange-traded fund (ETFs); and/or (4) corporate debt securities, such as commercial paper and other short-term unsecured promissory notes issued by businesses that are rated investment grade or of comparable quality.

Investments by Registered Investment Companies

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. However, registered investment companies are permitted to invest in other investment companies beyond the limits set forth in Section 12(d)(1) in rules under the 1940 Act, subject to certain conditions. The Fund may rely on Rule 12d1-4 of the 1940 Act, which provides an exemption from Section 12(d)(1) that allows the Fund to invest beyond the limits set forth in Section 12(d)(1) if the Fund satisfies certain conditions specified in Rule 12d1-4, including, among other conditions, that the Fund and its advisory group will not control (individually or in the aggregate) an acquired fund (e.g., hold more than 25% of the outstanding voting securities of an acquired fund that is a registered open-end management investment company).

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

There can be no assurance that the Fund will achieve their respective investment objectives. 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. The Fund’s 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.

In addition, the Fund’s investments in derivatives are subject to the following risks:

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. The value of the options contracts in which the Fund invests is substantially influenced by the value of the securities underlying the options contracts. 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 as the underlying instrument. There may at times be an imperfect correlation between the movement in 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 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. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Fund’s portfolio moves against its options positions, potentially resulting in a complete loss of the premiums paid.

MANAGEMENT

Investment Adviser

Tidal Investments LLC (the “Adviser”), located at 234 West Florida Street, Suite 203, Milwaukee, Wisconsin 53204, is an SEC registered investment adviser and a Delaware limited liability company. Tidal was founded in March 2012 and is dedicated to understanding, researching and managing assets within the expanding ETF universe. As of [ ], Tidal had assets under management of approximately $[ ] billion and served as the investment adviser or sub-adviser for [ ] registered funds.

Tidal serves as investment adviser to the Fund and has overall responsibility for the general management and administration of the Fund pursuant to an investment advisory agreement with the Trust, on behalf of the Fund (the “Advisory Agreement”). The Adviser is responsible for trading portfolio securities and financial instruments for the Fund, including selecting broker-dealers to execute purchase and sale transactions. The Adviser also arranges for transfer agency, custody, fund administration, and all other related services necessary for the Fund to operate. For the services provided to the Fund, the Fund pays the Adviser a unitary management fee of [ ]%, which is calculated daily and paid monthly, at an annual rate based on the Fund’s average daily net assets.

Under the Advisory Agreement, in exchange for a single unitary management fee from the Fund, the Adviser has agreed to pay all expenses incurred by the Fund except for interest charges on any borrowings made for investment purposes, dividends and other expenses on securities sold short, taxes, brokerage commissions and other expenses incurred in placing orders for the purchase and sale of securities and other investment instruments, acquired fund fees and expenses, accrued deferred tax liability, extraordinary expenses, distribution fees and expenses paid by the Fund under any distribution plan adopted pursuant to Rule 12b-1 under the 1940 Act, and the unitary management fee payable to the Adviser (collectively, the “Excluded Expenses”).

A discussion regarding the basis for the Board’s approval of the Fund’s Advisory Agreement will be available in the Fund’s [Annual/Semi-Annual] Certified Shareholder report to shareholders on Form N-CSR for the period ended [ ].

Portfolio Managers

The following individuals (each, a “Portfolio Manager”) have served as portfolio managers of the Fund since inception and are jointly and primarily responsible for the day-to-day management of the Fund.

Stephen Foy, Portfolio Manager for the Adviser

Mr. Foy joined Tidal in 2024 and is Senior Vice President of Trading and Co-Head of Tidal’s ETF Trading and Portfolio Management team. He previously oversaw Invesco ETF Services from 2021 to 2024, including middle and back-office operations as well as portfolio implementation for all equity and alternative ETFs. Mr. Foy holds an MBA from Johns Hopkins University and spent five years in ETF Portfolio Management at ProShares from 2016 to 2021. He brings a robust portfolio management background across a wide array of strategies and asset classes. Throughout his career, he has led global teams through hundreds of product launches, organizational changes, and technological and operational transformations.

Christopher P. Mullen, Portfolio Manager for the Adviser

Christopher P. Mullen serves as Portfolio Manager at the Adviser, having joined the firm in January 2024. From September 2019 to December 2023, he was a Portfolio Manager at Vest Financial LLC, where he managed exchange-traded funds, mutual funds and retirement fund portfolios. Mr. Mullen previously served as a Senior Portfolio Analyst at ProShares Advisors LLC from September 2016 until September 2019.

Mr. Mullen received a Master of Business Administration from the University of Maryland. He also holds a dual bachelor’s degree in global politics and history from Marquette University.

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 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 its 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. 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 does not impose any 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 the Fund’s 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 held by the Fund or is determined to be unreliable, the security will be valued at fair value estimates under guidelines established by the Adviser (as described below).

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.

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’s valuation procedures. The Adviser will fair value Fund investments whose market prices are not “readily available” or are deemed to be unreliable. 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.

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. 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 SAI. 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

The Fund intends to pay out dividends and interest income, if any, monthly, and distribute any net realized capital gains to its shareholders at least annually. For federal income tax purposes, distributions of net investment income are generally taxable 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. Distributions of short-term capital gain will generally be taxable as ordinary income. Dividends and distributions are generally taxable to you whether you receive them in cash or reinvest them in additional Shares.

Distributions reported by the Fund as “qualified dividend income” are generally taxed to non-corporate shareholders at rates applicable to long-term capital gains, provided 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. Given the investment strategies of the Fund, it is unlikely that any dividends paid by the Fund will be qualified dividends or be eligible for the corporate dividends paid deduction.

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 shares of the Fund 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 even if they are paid from income or gains earned by the Fund before your investment (and thus were included in the Shares’ NAV when you purchased your Shares).

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

If you are neither a resident nor a citizen of the United States or if you are a foreign entity, distributions (other than Capital Gain Dividends) paid to you by the Fund will generally be subject to a U.S. withholding tax at the rate of 30%, unless a lower treaty rate applies. 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 taxable 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 of the Fund are acquired, including through reinvestment of dividends, within a 61-day period beginning 30 days before and ending 30 days after the 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 they might not have recognized if they 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, 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 assets of the respective Fund 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 of the Fund 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 any 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.
