Investment Objective

The Defiance AI Magnificent 10 ETF (the “Fund”) seeks to track the performance, before fees and expenses, of the BITA AI Magnificent 10 Select Index (the “Index”).

Fees and Expenses of the Fund 

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

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then hold or redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in total annual fund operating expenses or in the Example, affect the Fund’s performance. Because the Fund has not commenced operations as of the date of this Prospectus, portfolio turnover information is not yet available.

Principal Investment Strategies

The Fund is an exchange-traded fund (“ETF”) that uses a “passive management” (or indexing) approach to track the performance, before fees and expenses, of the Index. The Index tracks the performance of 10 publicly-listed equity securities, operating across the most critical business vertical of the artificial intelligence (“AI”) value chain (“AI Magnificent 10 Companies”). The Index is owned, calculated, administered, and disseminated by BITA GmbH (“Index Provider”). 

The Index

The Index is rules-based. The Index tracks the performance of 10 publicly-listed equity securities operating across the most critical business verticals of the AI value chain. The equity securities included in the Index may include common stock, including from foreign companies, and depositary receipts. These business verticals are:

Construction of the Index begins with the eligible universe of securities. Please see the prospectus section titled “Additional Information About the Fund,” for the list of securities comprising the eligible universe, as of the date of this Prospectus. In addition, initial public offerings from companies with more than 50% exposure to any of the business verticals noted above are also eligible for inclusion.

All securities in the eligible universe are then ranked by free float market capitalization in descending order. The top 10 securities are selected for possible inclusion in the Index. In the case of a tie at the same ranking position, the security with the highest 3-month average daily traded value is ranked higher.

If a company has more than one share class that qualifies on a stand-alone basis for the Index, only the highest ranked share class, as ranked by its 3-month average daily traded value, will be considered for composition.

Final constituents are equally weighted.

The Index is reconstituted and rebalanced quarterly in January, April, July, and October at the close of business on the 2^nd Friday of the rebalancing month after market close, with such rebalancing based on constituent data as of the close of business 10 business days prior to such month.

The Fund’s Investment Strategy

The Fund will invest all, or substantially all, of its assets in (i) the component securities that make up the Index, and/or (ii) options and swap contracts that provide indirect exposure to the component securities that make up the Index. The Fund’s use of options and swaps will be largely driven by its intention to qualify for treatment as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”), which limits the Fund’s ability to invest in a small number of issuers. The use of options and swaps is intended to allow the Fund to maintain its RIC qualification during periods where there are a small number of Index constituents and the use of options and swaps may be extensive during such periods. The Fund’s portfolio will be reconstituted and rebalanced in accordance with the Index’s reconstitution and rebalancing schedule.

Under normal circumstances, at least 80% of the Fund’s net assets, plus borrowings for investment purposes, will be invested in AI Magnificent 10 Companies and/or financial instruments (such as options and swaps) that provide indirect exposure to AI Magnificent 10 Companies.

The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it generally will invest in all of the Index components. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Index as a whole, when the Adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index). The Fund will concentrate its investments (invest more than 25% of its assets) in the securities of a particular industry or group of related industries to the same extent as the Index. As of July 24, 2026, the Index is concentrated in the Semiconductors and Semiconductor Equipment group of industries.

The Fund is classified as “non-diversified” under the 1940 Act.

The Fund may invest in securities or other investments not included in the Index, but which the Adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).

The Fund will invest in collateral, including U.S. government securities (such as bills, notes and bonds issued by the U.S. Treasury) and money market funds. The collateral investments are designed to provide liquidity, serve as margin, or otherwise collateralized the Fund’s investments in derivative instruments (i.e., options and swaps).

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. In addition, the Fund presents risks not traditionally associated with other ETFs. 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.

Artificial Intelligence Risk. Issuers engaged in artificial intelligence typically have high research and capital expenditures and, as a result, their profitability can vary widely, if they are profitable at all. The space in which they are engaged is highly competitive and issuers’ products and services may become obsolete very quickly. These companies are heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. The issuers are also subject to legal, regulatory and political changes that may have a large impact on their profitability. A failure in an issuer’s product or even questions about the safety of the product could be devastating to the issuer, especially if it is the marquee product of the issuer. It can be difficult to accurately capture what qualifies as an artificial intelligence company.

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.

Concentration Risk. To the extent that the Fund concentrates in an industry, it will be subject to the risk that economic, political, or other conditions that have a negative effect on that industry will negatively impact the Fund to a greater extent than if its assets were invested in a wider variety of industries.

Sector and Industry Risks. The Fund is expected to be subject to the following sector and industry risks:

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect daily 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. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.

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

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 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 options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund’s options contracts are exercised or expire it may enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses.

Swap Agreements. 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.

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.

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 Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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.

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.

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.

IPO Risk. The Fund may purchase securities of companies that are offered in an IPO. The risk exists that the market value of IPO shares will fluctuate considerably due to factors such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs, because such investments would have a magnified impact on the Fund.

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

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

Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund 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.

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

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

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

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

Unrelated Business Risk. Many of the companies in which the Fund will invest have other business lines unrelated to one of the thematic categories. These other lines of business could adversely affect those firms’ operating results and, in turn, hurt the Fund’s performance. The operating results of companies with other business lines may fluctuate independently of the fluctuations in the relevant thematic category businesses. In addition, a particular company’s ability to engage in new business activities may expose it to additional risks for which it has less experience than its existing business lines. Despite a company’s possible success in activities linked to its use or one or more thematic categories, there can be no assurance that its other lines of business will not adversely affect the company’s business, financial condition, or market value. In addition, a particular company’s unrelated business may impact the Fund’s investment returns and it may be difficult to isolate thematic category-related returns from other return sources.

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 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 2026.

Christopher P. Mullen, Portfolio Manager for the Adviser, has been a portfolio manager of the Fund since its inception in 2026.

Purchase and Sale of Shares

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

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

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

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

Tax Information

Fund distributions are generally taxable 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.
