Summary Prospectus by Investment Company (Form 497K)

Before you invest, you may want to review the Fund's Prospectus, which contains more information about the Fund and its risks. You can find the Fund's Statutory Prospectus and Statement of Additional Information and other information about the Fund online at https://mast-etfs.com/. You may also obtain this information by calling collect at 1-833-829-0010 or by sending an e-mail request to [email protected]. The Fund's Prospectus and Statement of Additional Information, both dated August 18, 2026, as each may be amended or supplemented, are incorporated by reference into this Summary Prospectus.

Investment Objective

The Mast HedgeIndex Managed Futures Strategy ETF (the "Fund") seeks to achieve positive absolute returns that have a low correlation to the returns of broad stock and bond markets.

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) The Fund invests in a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands. "Other Expenses" include expenses of both the Fund and the wholly-owned subsidiary. "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. During the fiscal year ended October 31, 2025, the portfolio turnover rate of the Predecessor Fund (defined below) was 0% of the average value of its portfolio.

Principal Investment Strategies

The Fund is an actively managed exchange-traded fund ("ETF") that seeks diverse exposure to macro trading opportunities such as significant price trends, both up and down, across asset classes, geographies and time horizons. The Fund may take long and/or short positions in asset classes, and Manteio Scalable Technologies LLC ("Mast Investments" or the "Advisor"), the Fund's investment advisor, dynamically adjusts its exposure to individual asset classes utilizing trend-following and macro trading approaches. The 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 in frequent and active trading.

The Fund seeks to achieve its investment objective by investing directly and/or indirectly through its wholly-owned subsidiary organized under the laws of the Cayman Islands (the "Subsidiary") in securities and derivative instruments including, but not limited to, equity index futures and options, swaps on equity index futures, equity swaps, interest rate futures and options, fixed income futures and options, swaps on fixed income futures, commodity and commodity index-linked futures and options, swaps on commodity and commodity index-linked futures, currency futures and options, swaps on currency futures, currency forwards and equity-, fixed income-, and commodity-notes. When used in this Prospectus, the term "Fund" includes the Subsidiary and the term "invest" includes investments the Fund makes directly and through the Subsidiary. 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.

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. The Fund's return is expected to be derived principally from changes in the value of securities and its portfolio is expected to consist principally of securities. 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 will enter into short positions, and it may use futures and swaps or sell a security short to do so. For example, the Fund may enter into a futures contract pursuant to which it agrees to sell an asset (that it does not currently own) at a specified price at a specified point in the future. This gives the Fund a short position with respect to the asset. At times, the Fund may have significant short positions.

The Fund intends to make investments through the Subsidiary and may invest up to 25% of its total assets in the Subsidiary. The Fund will invest in the Subsidiary primarily to gain exposure to the commodities markets and crypto assets within the limitations of the U.S. federal tax laws, rules and regulations that apply to regulated investment companies. Generally, the Subsidiary will invest in long and short commodity-linked futures and swaps, but it may also invest in other types of futures, swaps and options, as well as certain money market instruments, including U.S. government securities, money market fund shares, repurchase agreements and other high-quality, short-term fixed income instruments. The primary purpose of the money market instruments held by the Subsidiary will be to serve as collateral for the Subsidiary's derivative positions; however, these instruments may also earn income for the Subsidiary. In addition, the Subsidiary may also invest in exchange-traded products that are listed and traded on U.S. exchanges and primarily hold crypto assets (i.e., bitcoin, ether, or other cryptocurrencies) ("Crypto Asset ETPs") and futures contracts linked to crypto assets ("Crypto Asset Futures"). Crypto assets (also referred to as "cryptocurrencies", "virtual currencies", and "digital currencies") are digital assets that are designed to act as a medium of exchange. Crypto assets are not issued by a government, bank, or central organization, and they exist via online, peer-to-peer computer networks that host public transaction ledgers where transfers are recorded on a blockchain. The Fund, through the Subsidiary, may have exposure to crypto assets equal to up to 10% of the Fund's net assets. The Subsidiary is managed by the Advisor and has the same objective as the Fund.

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. The principal risks described below reflect the aggregate operations of the Fund and its Subsidiary.

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.

Commodity Exposure Risk. The Fund's and the Subsidiary's investments in commodity-linked derivative instruments may subject the Fund to greater volatility than investments in traditional securities, particularly if the investments involve leverage. The value of commodity-linked derivatives instruments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or sectors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. Use of leveraged commodity-linked derivatives creates an opportunity for increased return but, at the same time, creates the possibility for greater loss (including the likelihood of greater volatility of the Fund's NAV), and there can be no assurance that the Fund's use of leverage will be successful.

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.

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.

Crypto Asset Risk. Crypto assets, such as bitcoin and ether, are digital assets that are designed to act as a medium of exchange. Despite being referred to as "currencies," crypto assets are not widely accepted as a medium of exchange, and there is no guarantee that they will ever be accepted as such. The value of the Fund's indirect

investments in crypto assets, through Crypto Asset ETPs and Crypto Asset Futures, is subject to fluctuations in the value of the underlying crypto assets. The value of a crypto asset is determined by the supply of and demand for the crypto asset in the global market, which consists of transactions on electronic exchanges. Pricing on exchanges and other venues can be volatile and can adversely affect the value of the Fund's exposure to the crypto asset. Currently, there is relatively limited use of crypto assets in the retail and commercial marketplace in comparison to the relatively large use of crypto assets by speculators, thus contributing to price volatility that could adversely affect the Fund's investments. Crypto asset transactions are irrevocable, and stolen or incorrectly transferred crypto assets may be irretrievable. As a result, any incorrectly executed transactions could adversely affect the value of the Fund's investments in Crypto Asset ETPs and Crypto Asset Futures.

Crypto assets generally operate without central authority (such as a bank) and are not backed by any government; therefore crypto assets are not subject to the same degree of regulation as are registered U.S. securities. The reporting, accounting and auditing standards for crypto assets may differ from the standards for registered U.S. securities. Due to the unregulated nature and lack of transparency surrounding the operations of crypto asset platforms, which may experience fraud, manipulation, security failures or operational problems, as well as the wider crypto asset market, the value of a crypto asset and, consequently, the value of the Fund's investments in Crypto Asset ETPs and Crypto Asset Futures may be adversely affected.

The Fund will indirectly bear its proportionate share of management fees and other expenses that are charged by Crypto Asset ETPs in addition to its own direct expenses and will pay brokerage commissions in connection with the purchase and sale of shares of Crypto Asset ETPs. Like other exchange-traded products, the shares of Crypto Asset ETPs may be bought and sold in the secondary market and may trade at a premium or discount to their net asset value. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity in the secondary market, in which case such premiums or discounts may be significant and the bid-ask spread could widen. Although the shares are listed for trading on an exchange, it cannot be assumed that an active trading market for the shares will be maintained. The lack of an active trading market for the shares may result in limited market liquidity and losses when selling the shares.

In addition, Crypto Asset ETPs have a limited number of financial institutions that may act as authorized participants ("APs") and there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent that (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 such functions, shares may trade at a material discount to NAV, the bid-ask spread could widen, and shares could face trading halts and/or delisting.

Crypto Asset ETPs are not registered investment companies under the 1940 Act or commodity pools under the Commodity Exchange Act ("CEA"), and therefore investors in Crypto Asset ETPs do not have the regulatory protections associated with ownership of shares in an investment company registered under the 1940 Act or the protections afforded by the CEA. Moreover, as sponsors of Crypto Asset ETPs have a limited track record in operating investment vehicles that specifically deal with crypto assets, their experience may be inadequate or unsuitable to manage them.

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.

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 American Depositary Receipts ("ADRs") and Global Depositary Receipts ("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.

Equity Risk. The Fund may 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.

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. Debt securities rated below investment grade (often called "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.

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.

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.

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.

Repurchase Agreement Risk. Repurchase agreements typically involve the acquisition by the Fund of fixed-income securities from a selling financial institution such as a bank or broker-dealer. The Fund may incur a loss if the other party to a repurchase agreement is unwilling or unable to fulfill its contractual obligations to repurchase the underlying security.

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.

Subsidiary Risk. By investing in the Subsidiary, the Fund will be indirectly exposed to the risks associated with the Subsidiary's investments. The Subsidiary is not registered under the 1940 Act and, unless otherwise noted, is not itself subject to all of the investor protections of the 1940 Act. Changes in the laws of the United States, the

U.S. states or the Cayman Islands, under which the Fund and Subsidiary are organized and operated, as applicable, could prevent the Fund or the Subsidiary from operating as described in this Prospectus and could negatively affect the Fund and its shareholders.

Portfolio Turnover Risk. Active and frequent trading of the Fund's portfolio securities may lead to higher transaction costs and may result in a greater number of taxable transactions than would otherwise be the case, which could negatively affect the Fund's performance. A high rate of portfolio turnover is 100% or more.

Tax Risk. To qualify for the tax treatment available to regulated investment companies under the Code, the Fund must derive at least 90% of its gross income for each taxable year from sources treated as "qualifying income." Income derived from direct investments in commodities or certain crypto assets is not "qualifying income." In addition, the Internal Revenue Service (the "IRS") has issued a revenue ruling concluding that income and gains from certain commodity-linked derivatives does not constitute "qualifying income." Investment through the Subsidiary is expected to allow the Fund to gain exposure to the commodity markets and crypto assets within the limitations of the federal tax law requirements applicable to regulated investment companies. The tax treatment of the Fund's investment in commodity interests or in the Subsidiary could nevertheless be adversely affected by future legislation or Treasury regulations.

Investment through the Subsidiary may affect the timing and character of income and gain recognized by the Fund, and of distributions to shareholders. For example, the tax treatment of any gains/losses from trading in 1256 futures contracts, such as exchange-traded commodity futures contracts, are generally taxed 60% as long-term capital gains/losses and 40% short term capital gains/losses. However, because the Subsidiary is a "controlled foreign corporation" for U.S. federal income tax purposes, any income or gain recognized in respect of its investments in 1256 futures contracts will be passed through to the Fund as ordinary income, and distributions attributable to such income and gains will generally be taxable to shareholders as ordinary income.

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.

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

The Fund will commence operations and acquire the assets and liabilities of the Mast Managed Futures Strategy Fund, which operated as a mutual fund (the "Predecessor Fund"), a series of Investment Managers Series Trust III, through the reorganization of the Predecessor Fund into the Fund, which is expected to occur after the close of business on August 31, 2026 (the "Reorganization"). The Fund will be the surviving legal entity of the Reorganization and will adopt the accounting and performance history of the Predecessor Fund. The Predecessor Fund will be the accounting survivor of the Reorganization. Performance results shown in the bar chart and the performance table below for the periods prior to the Reorganization reflect the investment strategy and performance of the Predecessor Fund. However, the principal investment strategies of the Fund and the Predecessor Fund are substantially similar.

The bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Predecessor Fund's performance from year-to-year and by showing how the Predecessor Fund's average annual total returns based on net asset value compared to those of the Index and other market indices. The Fund's updated performance information is accessible on the Fund's website at https://mast-etfs.com/.

Calendar-Year Total Return (before taxes) of Predecessor Fund

* After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Portfolio Managers

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.
