Investment Objective

The Defiance Trillion Dollar Club Index ETF (the "Fund") seeks to track the performance, before fees and expenses, of the BITA Trillion Dollar Club 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.

Annual Fund Operating Expenses(1) (expenses that you pay each year as a percentage of the value of your investment)
Management Fee	0.49%
Distribution and/or Service (12b-1) Fees	0.00%
Other Expenses(2)	0.00%
Total Annual Fund Operating Expenses	0.49%

(1)	The Fund's investment adviser, Tidal Investments LLC (the "Adviser"), a Tidal Financial Group company, will pay, or require a sub-adviser to pay, all of the Fund's expenses, except for the following: advisory and sub-advisory fees, 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 Act (the "1940 Act"), 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
$50	$157

Portfolio Turnover

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

Principal Investment Strategies

The Fund is an exchange-traded fund ("ETF") that uses a "passive management" (or indexing) approach to track the performance, before fees and expenses, of the Index. The Index tracks the performance of (i) U.S. exchange-listed companies, and (ii) crypto assets (through Crypto ETFs (defined below)), subject to the Index rules described below), each with market capitalizations of $1 trillion or greater ("Trillion Dollar Assets"). Trillion Dollar Assets may include American Depositary Receipts ("ADRs") of foreign companies that are traded on a U.S. exchange. The Index is owned, calculated, administered, and disseminated by BITA GmbH ("Index Provider"). "Crypto assets" refers to digital or virtual assets that are issued or transferred using distributed ledger or blockchain technology (e.g., bitcoin).

The Index

I.

Eligible Universe

The Index's eligible universe includes:

(i)

U.S. exchange-listed companies, including ADRs of foreign companies.

(ii)

U.S. ETFs registered under the 1940 Act that offer exposure to a single crypto asset ("Crypto ETFs"). Crypto ETFs generally gain exposure to crypto assets through derivatives, such as futures contracts, that are valued based on the price of the applicable crypto assets.

The Fund does not invest directly in any crypto assets. Investors seeking direct exposure to one or more crypto assets should consider an investment other than the Fund.

II.

Constituent Selection

Companies and Crypto ETFs in the Index's eligible universe are screened based on market capitalization. Companies with market capitalizations of $1 trillion or greater are included in the Index. If a crypto asset has a market capitalization of $1 trillion or greater, and one or more Crypto ETFs offer exposure to it, the largest such Crypto ETF, based on total assets, is included in the Index. If no Crypto ETF offers exposure to the crypto asset, that crypto asset will be excluded from the Index. As of the date of this Prospectus, the only crypto asset meeting the eligibility criteria is bitcoin. Please see the prospectus section titled "Additional Information About the Fund," for more information about bitcoin.

During periods where there are fewer than five Trillion Dollar Assets, the five largest investments in the eligible universe will be included in the Index. Accordingly, there could be periods when the Index includes holdings that are not Trillion Dollar Assets. As of June 30, 2025, there were ten Trillion Dollar Assets.

III.

Weighting

When there are five or more Trillion Dollar Assets, each investment selected for inclusion in the Index receives equal weight. When there are less than five Trillion Dollar Assets, the Trillion Dollar Assets will receive larger weightings than other portfolio holdings to ensure the Fund complies with its policy of investing at least 80% of its net assets in Trillion Dollar Assets, as discussed in greater detail below.

To the extent the Index is concentrated in a particular sector or industry, the Fund is expected to be concentrated in that same sector or industry. As of the date of this Prospectus, issuers in the information technology sector and semiconductor industry represented significant portions of the Index.

IV.

Rebalancing

Components of the Index are reconstituted and rebalanced on a monthly basis to maintain appropriate holdings and weightings in accordance with the Index's methodology.

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) swap contracts that provide indirect exposure to the component securities that make up the Index. The Fund's use of 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 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 swaps may be extensive during such periods.

Under normal circumstances, the Fund will invest at least 80% of its net assets, plus borrowings for investment purposes, in Trillion Dollar Assets and/or financial instruments (such as swaps) that provide indirect exposure to Trillion Dollar Assets.

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

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

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 collateralize the Fund's investments in derivative instruments (i.e., 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 per share ("NAV"), trading price, yield, total return and/or ability to meet its investment objective. For more information about the risks of investing in the Fund, see the section in the Fund's Prospectus titled "Additional Information About the Fund - Principal Risks of Investing in the Fund."

Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund's portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests.

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

○

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

○

Semiconductor Industry Risk. Semiconductor companies may face intense competition, both domestically and internationally, and such competition may have an adverse effect on their profit margins. Semiconductor companies may have limited product lines, markets, financial resources or personnel. Semiconductor companies' supply chain and operations are dependent on the availability of materials that meet exacting standards and the use of third parties to provide components and services. Semiconductor companies may rely on a limited number of suppliers, or upon suppliers in a single location, for certain materials, equipment or tools. Finding and qualifying alternate or additional suppliers can be a lengthy process that can cause production delays or impose unforeseen costs, and such alternatives may not be available at all. Production can be disrupted by the unavailability of resources, such as water, silicon, electricity, gases and other materials. Suppliers may also increase prices or encounter cybersecurity or other issues that can disrupt production or increase production costs.

The products of semiconductor companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Capital equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductor industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights would adversely affect the profitability of these companies.

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 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. When the Fund uses derivatives, there may be imperfect correlation between the value of the underlying security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.

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

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. If the Adviser is unable to enter into swap agreements that provide exposure to the underlying securities, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund's return.

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.

Bitcoin Investment Risks. The Fund's indirect investment in bitcoin through investment in ETFs exposes it to the unique risks of this emerging innovation. Bitcoin's price is highly volatile, and its market is influenced by the changing bitcoin network, fluctuating acceptance levels, and unpredictable usage trends. Not being a legal tender and operating outside central authority systems like banks, bitcoin faces potential government restrictions. For instance, some countries may limit or ban bitcoin transactions, negatively impacting its market value.

The risks associated with bitcoin include the possibility of fraud, theft, market manipulation, and security breaches in trading platforms. A small group of large bitcoin holders, known as "whales," can significantly influence bitcoin's price and may have the ability to manipulate the price. The largely unregulated nature of bitcoin and its trading venues heightens risks of fraudulent activities and market manipulation, which could affect bitcoin's price. For example, if a group of miners gains control over a majority of the bitcoin network, they could manipulate transactions to their advantage. Historical instances have seen bitcoin trading venues shut down due to fraud or security breaches, often leaving investors without recourse and facing significant losses.

Updates to bitcoin's software, proposed by developers, can lead to the creation of new crypto assets, or "forks," if not broadly adopted. This can impact bitcoin's demand and the Fund's performance. The extreme volatility of bitcoin's market price can result in shareholder losses. Furthermore, the operation of bitcoin trading platforms may be disrupted or cease altogether due to various issues, further affecting bitcoin's price and the Fund's investments.

The value of bitcoin has historically been subject to significant speculation, making trading and investing in bitcoin reliant on market sentiment rather than traditional fundamental analysis.

Bitcoin's price can be influenced by events unrelated to its security or utility, including instability in other speculative areas of the crypto/blockchain space, potentially leading to substantial declines in its value.

Risks associated with crypto asset trading platforms include fragmentation, regulatory non-compliance, and the possibility of enforcement actions by regulatory authorities, which could impact the valuation of bitcoin-linked derivatives held by the Fund.

The security of the Bitcoin Blockchain may be compromised if a single miner or group controls more than 50% of the network's hashing power, where hashing power refers to the computational capacity used to validate and secure transactions on the blockchain.

Proposed changes to the bitcoin protocol may not be universally adopted, leading to the creation of competing blockchains (forks) with different assets and participants, exemplified by past forks like Bitcoin Cash and Bitcoin SV.

The Bitcoin Blockchain protocol may contain vulnerabilities that attackers could exploit to disrupt its operation, potentially compromising the security and reliability of the network.

Emerging alternative public blockchains, particularly those emphasizing privacy through technologies like zero-knowledge cryptography, pose risks and challenges to the dominance of the Bitcoin Blockchain as a payment system.

Common impediments to adopting the Bitcoin Blockchain as a payment network include slow transaction processing, variability in transaction fees, and the volatility of bitcoin's price, which may deter widespread adoption by businesses and consumers.

The development and use of "Layer II solutions" are critical for the scalability and functionality of the Bitcoin Blockchain, but they also introduce risks such as off-chain transaction execution, which could affect transparency and security. Layer II solutions are off-chain protocols that improve scalability and reduce transaction costs by processing transactions outside the main blockchain network.

Adoption and use of other blockchains supporting advanced applications like smart contracts present challenges to the dominance of the Bitcoin Blockchain, potentially impacting its long-term relevance and utility in the evolving landscape of blockchain technology.

●

Crypto Assets Risk: Crypto assets like bitcoin, designed as mediums of exchange, are still an emerging asset class and are not presently widely used as such. They operate independently of any central authority or government backing and are subject to regulatory changes and extreme price volatility. The trading platforms for crypto assets are relatively new, largely unregulated or possibly operating out of compliance with regulations, and thus more vulnerable to fraud and failures compared to traditional, regulated exchanges. Shutdowns of these platforms due to fraud, technical glitches, or security issues can significantly affect crypto asset prices and market volatility.

●

Crypto Asset Markets Risk: The crypto asset market, particularly bitcoin, has experienced considerable volatility, leading to market disruptions and erosion of confidence among market participants. This instability and the resultant negative publicity could adversely affect the Fund's reputation and trading prices. Ongoing market turbulence could significantly impact the value of the Fund's share. Inclusion of crypto assets in the Index may result in higher volatility for the Fund than if crypto assets were not included in the Index. In addition, there may be periods when crypto assets comprise a significant portion of the Fund, which may may lead to increased risk.

●

Blockchain Technology Risk: Blockchain technology, which underpins bitcoin and other crypto assets, is relatively new, and many of its applications are untested. The adoption of blockchain and the development of competing platforms or technologies could affect its usage. Investments in companies or vehicles that utilize blockchain technology are subject to market volatility and may experience lower trading volumes compared to more established industries. Additionally, regulatory changes, internet disruptions, cybersecurity incidents, and intellectual property disputes could further affect the adoption and functionality of blockchain technology.

Crypto ETF Risk. The Fund will incur higher and duplicative expenses because it invests in Crypto ETFs (e.g., bitcoin ETFs). There is also the risk that the Fund may suffer losses due to the investment practices of the Crypto ETFs. The Fund will be subject to substantially the same risks as those associated with the direct ownership of securities and investments held by Crypto ETFs. Additionally, Crypto ETFs are also subject to the "ETF Risks" described herein.

Bitcoin ETF Risks: Investing in an ETF that provides exposure to bitcoin carries significant risks. These risks include high market volatility, which can be influenced by technological advancements, regulatory changes, and broader economic factors. When trading derivatives, liquidity risks and counterparty risks are substantial. Managing futures contracts can be complex and may affect the performance of the ETF. 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. Additionally, an ETF providing exposure to bitcoin, and consequently the Fund, is dependent on blockchain technology, which brings technological and cybersecurity risks, along with custodial challenges for securely storing crypto assets. The constantly evolving regulatory and legal landscape presents continuous compliance and valuation difficulties. Risks related to market concentration and network issues in the crypto asset sector further add complexity. Moreover, operational intricacies in managing crypto assets and potential market volatility can lead to losses for an ETF providing exposure to bitcoin.

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.

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of actual shares and swap contracts of a single issuer does not exceed 25% of the Fund's value at the close of any quarter. If the value of actual shares and swap contracts on shares of a single issuer were to exceed 25% of the Fund's total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

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. Investors buying or selling Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers, as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. In addition, secondary market investors will also incur the cost of the bid-ask spread. The bid-ask spread varies over time for Shares based on trading volume and market liquidity, and is generally lower if Shares have more trading volume and market liquidity and higher if Shares have little trading volume and market liquidity. Further, a relatively small investor base in the Fund, asset swings in the Fund and/or increased market volatility may cause increased bid-ask spreads. Due to the costs of buying or selling Shares, including bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

○

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund's NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, 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 for trading 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. The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund's portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund's investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics.

Market Capitalization Risk

○

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.

Money Market Instrument Risk. The Fund may use a variety of money market instruments for cash management purposes, including money market funds and depositary accounts. The Fund will incur expenses when investment in money market instruments, which will reduce performance. 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 Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Passive Investment Risk. The Fund is not actively managed and does not attempt to outperform 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, Calculation Agent, 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, Calculation Agent or other applicable party for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

U.S. Government Obligations Risk. The Fund may invest in securities issued by the U.S. government. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, 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 Although U.S. Treasuries are backed by the U.S. government, those government policies may change both in terms of the payment of interest and in the payment of principal. Furthermore, while holding a Treasury until maturity can guarantee principal, selling a treasury prior to maturity or buying a treasury subsequent to issue date may put principal at risk.

Performance

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

Management

Investment Adviser: Tidal Investments LLC, a Tidal Financial Group company, serves as investment adviser to the Fund.

Portfolio Managers:

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

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

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

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

Purchase and Sale of Shares

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

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

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

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

Tax Information

Fund distributions are generally taxable to shareholders as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is in an individual retirement account ("IRA") or other tax-advantaged account.

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.
