Investment Objective

The Mast HedgeIndex Adaptive Equities 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"). Investors may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example set forth below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

​(1) "Other Expenses" are estimated for the current fiscal year. Actual expenses may differ from estimates.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then 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 at current levels. This example does not include the brokerage commissions that investors may pay to buy and sell Shares.

Although your actual costs may be higher or lower, your costs, based on these assumptions would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or "turns over" its portfolio). A higher portfolio turnover will cause the Fund to incur additional 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, may affect the Fund's performance.

Principal Investment Strategies

The Fund is an actively managed exchange-traded fund ("ETF") that seeks to achieve its investment objective by utilizing an adaptive macro-strategy to allocate across global equity markets. The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities. Equity securities include common stock, preferred stock, warrants and rights, investment company securities, real estate investment trusts ("REITs"), American Depository Receipts ("ADRs"), European Depository Receipts ("EDRs"), Global Depository Receipts ("GDRs") and equity-related derivatives, such as futures, forwards, exchange-traded and over-the-counter put and call options (both covered and uncovered) and swaps, that provide exposure to such investments. The Fund may invest up to 20% of its assets in a broad range of instruments, including bonds, currencies, futures, forwards, exchange-traded and over-the-counter put and call options (both covered and uncovered) and swaps. There are no geographic limits on the Fund's holdings, and the Fund may have exposure to U.S. and non-U.S. securities and currencies.

Manteio Scalable Technologies LLC ("Mast Investments" or the "Advisor"), the Fund's investment advisor, incorporates research-driven, quantitative models proprietary to its corporate affiliate, HedgeIndex LLC ("HedgeIndex"), into its investment selection process for the Fund. HedgeIndex has been a provider of alternative indexes, models, and data since 1999. The Advisor has entered into a licensing agreement with HedgeIndex and intends to use its quantitative models as a component in the Advisor's management of the Fund. The Advisor makes all determinations as to how the models should be applied to the Fund's investment strategies, and how to allocate the Fund's assets among its investments. The Advisor retains full discretion with respect to all investment management decisions made for the Fund. The Advisor's use of such models may vary based on market factors and economic trends as determined by the Advisor.

The Fund may engage extensively in short sales of securities. When the Fund sells a security short, it borrows the security from a third party and sells the security at the then current market price. The Fund is then obligated to buy the security on a later date so that it can return the security to the lender. The Fund utilizes a dynamic long-short equity strategy, investing up to approximately 135% of its net assets in long positions and up to approximately 60% of its net assets in short positions, resulting in net market exposure to global equity markets that, over time, averages approximately 100%, while potentially aggressively concentrating views on individual stocks. The Advisor seeks to exploit "macro" market inefficiencies such as repeated cycles of asset prices overshooting and mean reverting which may not be justifiable given the concurrent changes in economic fundamentals, while simultaneously adapting to and harnessing the particularities of the contemporaneous macro regime, namely the interactions between (i) the standard inventory cycle; (ii) secular trends relating to the constant transformation of technology, demographics, and geopolitical trends; and (iii) monetary regimes and disruptive shocks. The Fund's use of leverage and short-selling is expected to vary through time.

The Fund may invest in bonds issued or guaranteed by domestic and international corporations or governments. The Fund may invest in bonds of any maturity, duration, and credit quality (both investment grade and below investment grade (commonly referred to as "high yield securities" or "junk bonds")). High yield securities (commonly referred to as "junk" bonds or below investment-grade securities) are instruments that are rated BB+ or lower by S&P Global Ratings or Fitch Inc. or Ba1 or lower by Moody's or equivalent ratings by another registered nationally recognized statistical rating organization ("NRSRO"), or, if unrated by an NRSRO, of comparable quality in the opinion of the Advisor. The Fund may invest globally (including in emerging markets. In addition, the Fund may have exposure to issuers of any size and credit quality.

The Fund also invests a significant portion of its assets in investment grade money market instruments, which may include, but are not limited to, U.S. government securities, U.S. government agency securities, short-term fixed income securities, repurchase agreements, money market mutual fund shares, and cash and cash equivalents. The Fund's money

market instrument holdings may serve as collateral for the Fund's derivative positions and may also earn income for the fund. In addition, the Fund may lend its portfolio securities to broker-dealers and other institutions as a means of earning additional income.

The Fund's use of futures, forwards, swaps and certain other financial instruments will have the economic effect of financial leverage. Financial leverage magnifies the exposure to the swings in prices of an asset class underlying a financial instrument and results in increased volatility, which means that the Fund has the potential for greater gains and losses, than if the Fund did not use financial instruments with leverage. A decline in the Fund's assets due to losses magnified by the financial instruments providing leveraged exposure may require the Fund to liquidate portfolio positions when it may not be advantageous to do so in order to satisfy its obligations, to meet redemption requests or to meet the applicable requirements of the 1940 Act, and the rules thereunder.

The Fund is "non-diversified," meaning that a relatively high percentage of its assets may be invested in a limited number of issuers of securities.

The Advisor has engaged Tidal Investments LLC ("Tidal" or the "Sub-Advisor") to serve as investment sub-advisor to the Fund. The Sub-Advisor is responsible for implementing the Fund's investment program by, among other things, trading portfolio securities and performing related services, rebalancing the Fund's portfolio in accordance with investment strategy provided by the Advisor.

Principal Risks

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund's investment objective will be achieved.

Equity Risk. The Fund will obtain exposure to equity securities. The value of equity securities may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. Changes in exchange rates and interest rates, and the imposition of sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and/or other governments may adversely affect the values of the Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs and GDRs. Unsponsored ADRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends. Emerging markets tend to be more volatile than the markets of more mature economies and generally have less diverse and less mature economic structures and less stable political systems than those of developed countries.

Currency Risk. The values of investments in securities denominated in foreign currencies increase or decrease as the rates of exchange between those currencies and the U.S. dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile and are affected by factors such as general economic conditions, the actions of the United States and foreign governments or central banks, the imposition of currency controls, and speculation.

Short Sales Risk. In connection with a short sale of a security or other instrument, the Fund is subject to the risk that instead of declining, the price of the security or other instrument sold short will rise. If the price of the security or other instrument sold short increases between the date of the short sale and the date on which the Fund replaces the security or other instrument borrowed to make the short sale, the Fund will experience a loss,

which is theoretically unlimited since there is a theoretically unlimited potential for the market price of a security or other instrument sold short to increase. Shorting options or futures may have an imperfect correlation to the assets held by the Fund and may not adequately protect against losses in or may result in greater losses for the Fund's portfolio.

Derivatives Risk. Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. Major types of derivatives include futures, options, swaps and forward contracts. Using derivatives exposes the Fund to additional or heightened risks, including leverage risk, liquidity risk, valuation risk, market risk, counterparty risk, and credit risk. Derivatives transactions can be highly illiquid and difficult to unwind or value, they can increase Fund volatility, and changes in the value of a derivative held by the Fund may not correlate with the value of the underlying instrument or the Fund's other investments. Many of the risks applicable to trading the instruments underlying derivatives are also applicable to derivatives trading. However, derivatives are subject to additional risks such as operational risk, including settlement issues, and legal risk, including that underlying documentation is incomplete or ambiguous. For derivatives that are required to be cleared by a regulated clearinghouse, other risks may arise from the Fund's relationship with a brokerage firm through which it submits derivatives trades for clearing, including in some cases from other clearing customers of the brokerage firm.

Futures Risk. The Fund's use of futures contracts expose the Fund to leverage and tracking risks because a small investment in futures contracts may produce large losses and futures contracts may not be perfect substitutes for securities. The value of a futures contract tends to increase and decrease in correlation with the value of the underlying instrument. Risks of futures contracts may arise from an imperfect correlation between movements in the price of the futures and the price of the underlying instrument. The Fund's use of futures contracts exposes the Fund to leverage risk because of the small margin requirements relative to the value of the futures contract. A relatively small market movement will have a proportionately larger impact on the funds that the Fund has deposited or will have to deposit with a broker to maintain its futures position. Leverage can lead to large losses as well as gains. While futures contracts are generally liquid instruments, under certain market conditions they may become illiquid. Futures exchanges may impose daily or intraday price change limits and/or limit the volume of trading. Additionally, government regulation may further reduce liquidity through similar trading restrictions. As a result, the Fund may be unable to close out its futures contracts at a time that is advantageous. The price of futures can be highly volatile; using them could lower total return, and the potential loss from futures could exceed the Fund's initial investment in such contracts.

Swaps Risk. A swap is a two-party contract that generally obligates the parties to exchange payments based upon a specified reference security, index or index component. Swaps can involve greater risks than direct investment in securities or other similar instruments, because swaps may be leveraged and are subject to counterparty risk (e.g., the risk that the other party to the transaction defaults on its obligations), credit risk and valuation risk (i.e., swaps may be difficult to value). Swaps may also be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Options Risk. Purchasing and writing put and call options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities. If the Fund is not able to sell an option held in its portfolio, it would have to exercise the option to realize any profit and would incur transaction costs upon the purchase or sale of the underlying securities. Ownership of options involves the payment of premiums, which may adversely affect the Fund's performance. To the extent that the Fund invests in over-the-counter options, the Fund may be exposed to counterparty risk.

Forwards Risk. Forwards are not exchange-traded and therefore no clearinghouse or exchange stands ready to meet the obligations of the contracts. Thus, the Fund faces the risk that its counterparties may not perform their obligations. Forward contracts are not regulated by the Commodity Futures Trading Commission (the "CFTC") and therefore, the Fund will not receive any benefit of CFTC regulation when trading forward.

Speculative Exposure Risk. Gains or losses from speculative positions in a derivative may be much greater than the derivative's original cost. For example, potential losses from swaps and speculative short sales are unlimited.

Leveraging Risk. Certain Fund transactions, such as entering into futures contracts, options and short sales, may give rise to a form of leverage. Leverage can magnify the effects of changes in the value of the Fund's investments and make the Fund more volatile. Leverage creates a risk of loss of value on a larger pool of assets than the Fund would otherwise have had, potentially resulting in the loss of all assets. The Fund may also have to sell assets at inopportune times to satisfy its obligations in connection with such transactions.

Liquidity Risk. The Fund may not be able to sell some or all of the investments that it holds due to a lack of demand in the marketplace or other factors such as market turmoil, or if the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs it may only be able to sell those investments at a loss. Illiquid assets may also be difficult to value.

Preferred Stock Risk. Preferred stock represents an equity interest in a company that generally entitles the holder to receive, in preference to the holders of other stocks such as common stock, dividends and a fixed share of the proceeds resulting from a liquidation of the company. The market value of preferred stock is subject to company-specific and market risks applicable generally to equity securities and is also sensitive to changes in the company's creditworthiness, the ability of the company to make payments on the preferred stock, and changes in interest rates, typically declining in value if interest rates rise.

Convertible Securities Risk. Convertible securities are subject to market and interest rate risk and credit risk. When the market price of the equity security underlying a convertible security decreases the convertible security tends to trade on the basis of its yield and other fixed income characteristics, and is more susceptible to credit and interest rate risks. When the market price of such equity security rises, the convertible security tends to trade on the basis of its equity conversion features and be more exposed to market risk. Convertible securities are typically issued by smaller capitalized companies with stock prices that may be more volatile than those of other companies.

Real Estate Investment Trust (REIT) Risk. The Fund's investment in REITs will subject the Fund to risks similar to those associated with direct ownership of real estate, including losses from casualty or condemnation, and changes in local and general economic conditions, supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses.

Fixed Income Securities Risk. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to changes in an issuer's credit rating or market perceptions about the creditworthiness of an issuer. Generally, fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, and longer-term and lower rated securities are more volatile than shorter-term and higher rated securities.

Credit Risk. If an issuer or guarantor of a debt security held by the Fund or a counterparty to a financial contract with the Fund defaults or is downgraded or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of the Fund's portfolio will typically decline.

Interest Rate Risk. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, with longer-term securities being more sensitive than shorter-term securities. For example, the price of a security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Generally, the longer the maturity and duration of a bond or fixed rate loan, the more sensitive it is to this risk. Falling interest rates also create the potential for a decline in the Fund's income. Changes in governmental policy, rising inflation rates, and general economic developments, among other factors, could cause interest rates to increase and could have a substantial and immediate effect on the values of the Fund's investments. In addition, a potential rise in interest rates may result in periods of volatility and increased redemptions that might require the Fund to liquidate portfolio securities at disadvantageous prices and times.

High Yield ("Junk") Bond Risk. High yield bonds are debt securities rated below investment grade (often called "junk bonds"). Junk bonds are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment-grade securities. Companies issuing high yield bonds are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings.

Lack of Correlation Risk; Hedging Risk. There can be no assurance that the Fund's hedges will be effective. Any decrease in negative correlation or increase in positive correlation between the positions the Advisor anticipated would be offsetting (such as short and long positions in securities or currencies held by the Fund) could result in significant losses for the Fund.

Lending Portfolio Securities Risk. The Fund may lend its portfolio securities to broker-dealers and banks, provided that it may not lend securities if, as a result, the aggregate value of all securities loaned would exceed 33 1/3% of its total assets. The collateral, including the investment of any cash collateral, is subject to market depreciation. In the event of bankruptcy or other default of the borrower, the Fund could experience delays in both liquidating the loan collateral and recovering the loaned securities and losses. The collateral (including any investment of cash collateral) is not subject to the percentage limitations on the Fund's investments described elsewhere in this prospectus.

Counterparty Risk. The Fund will be exposed to the credit of the counterparties to over-the-counter ("OTC") derivative contracts and repurchase agreements and their ability to satisfy the terms of the agreements, which exposes the Fund to the risk that the counterparties may default on their obligations to perform under the agreements. In the event of a bankruptcy or insolvency of a counterparty, the fund could experience delays in liquidating the positions and significant losses, including declines in the value of its investment during the period in which the Fund seeks to enforce its rights, inability to realize any gains on its investment during such period, loss of collateral and fees and expenses incurred in enforcing its rights.

Non-Diversification Risk. The Fund is classified as "non-diversified," which means the Fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. Investment in securities of a limited number of issuers exposes the Fund to greater market risk and potential losses than if its assets were diversified among the securities of a greater number of issuers.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic, political, or geopolitical conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as tariffs, labor shortages or increased production costs and competitive conditions within an industry. In addition, local, regional or global events such as war, acts of terrorism, international conflicts, trade disputes, supply chain disruptions, cybersecurity events, technological advances (such as artificial intelligence ("AI") and machine learning), the spread of infectious illness or other public health issues, natural disasters or climate events, or other events could have a significant impact on a security or instrument. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market.

ETF Structure Risks. The Fund is an ETF, and, as a result of an ETF's structure, it is exposed to the following risks:

• Authorized Participant Concentration Risk. Only an authorized participant ("AP") may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that act as APs on an agency basis (i.e., on behalf of other market participants). To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to process creation or redemption orders, Shares may trade at a discount to the Fund's NAV and possibly face delisting.

• Cash Transaction Risk. To the extent the Fund sells portfolio securities to meet some or all of a redemption request with cash, the Fund may incur taxable gains or losses that it might not have incurred had it made redemptions entirely in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

• 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 difference between the price at which an investor is willing to buy Shares (the "bid" price) and the price at which an investor is willing to sell Shares (the "ask" price). This difference in bid and ask prices is often referred to as the "spread" or "bid-ask spread." The bid-ask spread varies over time for Shares based on trading volume and market liquidity, and 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. 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.

• Fluctuation of NAV Risk. 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). Differences in market price and NAV may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares will be closely related to, but not identical to, the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. These differences can be especially pronounced during times of market volatility or stress. During these periods, the demand for Shares may decrease considerably and cause the market price of Shares to deviate significantly from the Fund's NAV. When all or a portion of an ETF's underlying securities trade in a market that is closed when the market in which the ETF's shares are listed and trading is open, there may be changes from the last quote from the closed market and the value of such security during the ETF's domestic trading day, which could lead to differences between the market price of the ETF's shares and their underlying NAV.

• Market Maker Risk. If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's NAV and the price at which the Shares are trading on the Exchange, which could result in a decrease in value of the Shares. In addition, decisions by market makers or APs to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Shares trading at a discount to NAV and also in greater than normal intra-day bid-ask spreads for Shares.

• Shares are Not Individually Redeemable. Shares are only redeemable by the Fund at NAV if they are tendered in large blocks of shares called "Creation Units." Only APs may engage in such creation and redemption transactions directly with the Fund. Individual Shares may be sold on a stock exchange at their current market prices, which may be less, more, or equal to their NAV.

• Trading Issues Risk. Although the Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for such Shares will develop or be maintained. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange "circuit breaker" rules. Market makers

are under no obligation to make a market in the Shares, and APs are not obligated to submit purchase or redemption orders for Creation Units. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. Initially, due to the small asset size of the Fund, it may have difficulty maintaining its listings on the Exchange.

Active Management Risk. The Fund is actively-managed and its performance reflects investment decisions that the Advisor makes for the Fund. Such judgments about the Fund's investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Operational Risk. The Fund is exposed to operational risks arising from a number of 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 and the Advisor seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Valuation Risk. The sales price the Fund could receive for any particular portfolio investment may differ from the Fund's valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued by the Advisor using a fair value methodology. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the Advisor had not fair-valued the security or had used a different valuation methodology.

New Fund Risk. As of the date of this prospectus, the Fund has no operating history and currently has fewer assets than larger funds.

Government-Sponsored Entities Risk. The Fund's investment in U.S. government obligations may include securities issued or guaranteed as to principal and interest by the U.S. government, or its agencies or instrumentalities. There can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) when it is not obligated to do so.

Foreign Sovereign Risk. Foreign governments rely on taxes and other revenue sources to pay interest and principal on their debt obligations. The payment of principal and interest on these obligations may be adversely affected by a variety of factors, including economic results within the foreign country, changes in interest and exchange rates, changes in debt ratings, changing political sentiments, legislation, policy changes, a limited tax base or limited revenue sources, natural disasters, or other economic or credit problems. It is possible that a foreign sovereign may default on its debt obligations.

Recent Market Events. Periods of market volatility may occur in response to market events, public health emergencies, natural disasters or climate events, and other economic, political, and global macro factors. U.S. and international markets have recently experienced, and may continue to experience, periods of significant volatility due to various factors, including uncertainty regarding inflation and central banks' interest rate changes, the possibility of a national or global recession, trade tensions and tariffs, and political and geopolitical events. In addition, wars or threats of war and aggression, such as Russia's invasion of Ukraine and conflicts among nations and militant groups in the Middle East, have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally, each of which may negatively impact the Fund's investments. Damage to energy infrastructure from conflicts in the Middle East, reduced shipping through the Strait of Hormuz, and other energy supply constraints could also have long-term adverse impacts on the U.S. and world economies. Additionally, since the change in the U.S. presidential administration in 2025, the administration has pursued an aggressive foreign policy agenda,

including through suggestions that the United States should control certain sovereign foreign territories, attempts to restructure federal government agencies with international influence, and the imposition of tariffs and trade barriers on certain foreign countries, including China and long-time U.S. allies. These and other similar events could be prolonged and could adversely affect the value and liquidity of the Fund's investments and negatively impact the Fund's performance.

Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data (including private shareholder information), or proprietary information, or cause the Fund, the Advisor, Sub-Advisor and/or other service providers (including custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality. In an extreme case, a shareholder's ability to exchange or redeem Shares may be affected. The use of AI and machine learning could exacerbate these risks. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of those securities could decline if the issuers experience cybersecurity incidents.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Performance

As of the date of this prospectus, the Fund has not yet commenced operations and therefore does not have a performance history. Once available, the Fund's performance information will be accessible on the Fund's website at https://mast-etfs.com/ and will provide some indication of the risks of investing in the Fund.

Management

Investment Advisor

Manteio Scalable Technologies LLC is the Fund's investment advisor.

Sub-Advisor

Tidal Investments LLC

Portfolio Managers

The Fund's portfolio management team is comprised of Yung-Shin Kung, Portfolio Manager of the Advisor, Brett Johnson, Portfolio Manager of the Sub-Advisor, and Christopher P. Mullen, Portfolio Manager of the Sub-Advisor. Messrs. Kung, Johnson and Mullen have been primarily responsible for the day-to-day management of the Fund's portfolio since the Fund's inception in August, 2026.

Purchase and Sale of Shares

The Fund issues and redeems Shares on a continuous basis, at NAV, only in Creation Units" Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may only be purchased and sold on the secondary market through a broker-dealer. Since Shares trade on securities exchanges in the secondary market at their market price rather than their NAV, the Shares may trade at a price greater than (premium) or less than (discount) the Fund's net asset value. An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares in the secondary market (the "bid-ask spread"). Recent information, including the Fund's NAV, market price, premiums and discounts, and bid-ask spreads, is available online at https://mast-etfs.com/.

Tax Information

The Fund's distributions will generally be taxable as ordinary income or capital gains. A sale of Shares may result in capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank), the Advisor and Distribution Services, LLC, the Fund's distributor, may pay the intermediary for the sale of Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
