Before you invest, you may want to review the Fund’s prospectus and statement of additional information (“SAI”), which contain more information about the Fund and its risks. The current prospectus and SAI dated May 16, 2022, are incorporated by reference into this Summary Prospectus. You can find the Fund’s prospectus, reports to shareholders, and other information about the Fund online at www.stfm.com. You can also get this information at no cost by calling 1-866-590-9112 or by sending an e-mail request to ETF@usbank.com.

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 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:

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 the 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.

The Fund is an actively-managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective by allocating its investments among a combination of (i) U.S. equity securities or ETFs that, in the aggregate, seek to replicate the Nasdaq-100® Index (the “Index Allocation”), (ii) directly in, or in ETFs that hold, long-duration U.S. Treasury securities (the “Fixed Income Allocation”), and (iii) short-term U.S. Treasury bills, money market funds, and cash and/or cash equivalents (the “Cash Equivalents”). The Fund also may opportunistically employ an options spread strategy, as discussed in more detail below.

analysis factors, but is primarily quantitative in nature. The quantitative factors underlying the TUG model include, but are not limited to, asset class (i.e., equity and fixed income) and market volatility, as well as rates of change in both asset class price action (i.e., the price movement of securities in a particular asset class over time) and market volatility. The TUG Model is based on signals that are derived from a proprietary algorithm that tracks market price action across equities, fixed income, and commodities, to include rates of change in correlation and volatility. In response to shifts in price action, market volatility, and correlation of the two primary asset classes based on the TUG Model, the Adviser will adjust the Fund’s portfolio allocations between the Index Allocation and the Fixed Income Allocation and thereby seek to proactively adapt to current market conditions.

The TUG Model provides the opportunity to take advantage of both equity bull and bear markets through the use of strategic long equity positions in addition to long Treasury and money market positions. In seeking to capitalize upon the noncorrelation between equities and fixed income securities, the TUG Model will assess which asset class provides the best opportunity for growth in light of prevailing market conditions. For example, when the equity markets become indecisive, the TUG Model seeks to both protect and benefit the Fund from the periodic reversals in equities by allocating assets to bond and/or Cash Equivalents positions.

The TUG Model monitors several moving averages of various lengths to measure underlying trends within the Nasdaq-100® Index. Multiple buy and sell signals are incorporated into the TUG Model to take advantage of evolving market conditions. As a result, the TUG Model generates unique signals in both bullish and bearish markets, as the market tends to behave differently depending on the trend. A partial allocation (long or short) to Treasury bonds may be made when the equity signal is not at full strength.

The Adviser also may opportunistically invest in options to seek to enhance the Fund’s return. The Fund’s options spread strategy typically consists of two components: (i) selling call options on the Nasdaq-100® Index on up to 100% of the value of the equity securities held by the Fund to generate premium from such options, while (ii) simultaneously reinvesting a portion of such premium to buy call options on the same reference asset(s).

Short Call Options. A written (sold) call option gives the seller the obligation to sell shares of the reference asset at a specified price (“strike price”) until a specified date (“expiration date”). The writer (seller) of the call option receives an amount (premium) for writing (selling) the option. In the event the reference asset appreciates above the strike price and the holder exercises the call option, the Fund will have to pay the difference between the value of the reference asset and the strike price or deliver the reference asset (which loss is offset by the premium initially received), and in the event the reference asset declines in value, the call option may end up worthless and the Fund retains the premium. The call options written by the Fund will be collateralized by the Fund’s equity holdings at the time the Fund sells the options.

Long Call Options. When the Fund purchases a call option, the Fund pays an amount (premium) to acquire the right to buy shares of a reference asset at a strike price until the expiration date. In the event the reference asset appreciates in value above the strike price and the Fund exercises its call option, the Fund will be entitled to receive the difference between the value of the reference asset and the strike price (which gain is offset by the premium originally paid by the Fund), and in the event the reference asset closes below the strike price as of the expiration date, the call option may end up worthless and the Fund’s loss is limited to the amount of premium it paid.

The options purchased or sold by the Fund will typically have an expiration date approximately one month from the time of purchase or sale. The Fund expects the total value of the call options and the total value of the call options to each be up to 100% of the Fund’s net assets. The Fund will use a portion of the premium received from writing call options to purchase call options. Call options written by the Fund will typically have a strike price that is at, near, or higher than the current price of the reference asset, and call options purchased by the Fund will typically have a strike price that is higher (in some cases, significantly higher) than the current price of the reference asset. The call options used by the Fund will be traded on a national securities exchange and be settled in cash.

The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with those of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value (“NAV”), trading price, yield, total return and/or ability to meet its objective. The following risks could affect the value of your investment in the Fund:

•Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets or proprietary information, or cause the Fund, the Adviser, and/or other service providers (including custodians and financial intermediaries) to suffer data breaches or data corruption. Additionally, cybersecurity failures or breaches of the electronic systems of the Fund, the Adviser, or the Fund’s other service providers, market makers, Authorized Participants (“APs”) or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund's business operations, potentially resulting in financial losses to the Fund and its shareholders.

•Derivatives Securities Risk. The Fund invests in options that derive their performance from the performance of the Nasdaq-100 Index. Derivatives, such as the options in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, or are not correlated with the performance of their underlying asset or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives.

◦Options Risk. Selling (writing) and buying options are speculative activities and entail greater than ordinary investment risks. The Fund’s use of put options can lead to losses because of adverse movements in the price or value of the underlying asset, which may be magnified by certain features of the options. When selling a put option, the Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the underlying asset is below the strike price by an amount equal to or greater than the premium. Purchasing of put options involves the payment of premiums, which may adversely affect the Fund’s performance. Purchasing a put option gives the purchaser of the option the right to sell a specified quantity of an underlying asset at a fixed exercise price over a defined period of time. Purchased put options may expire worthless resulting in the Fund’s loss of the premium it paid for the option.

The value of an option may be adversely affected if the market for the option becomes less liquid or smaller, and will be affected by changes in the value or yield of the option’s underlying asset, an increase in interest rates, a change in the actual or perceived volatility of the stock market or the underlying asset and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the underlying asset. The Fund’s use of options may reduce the Fund’s ability to profit from increases in the value of the underlying asset. If the price of the underlying asset of an option is above the strike price of a written put option, the value of the option, and consequently of the Fund, may decline significantly more than if the Fund invested directly in the underlying asset instead of using options. While the Fund will segregate liquid assets at least equal in value to the maximum potential loss for the Fund, the Fund could still lose a significant amount or nearly all of its value if the price of an underlying asset changes significantly enough.

◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as 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., short positions and 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.

◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and 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 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.

•Fixed Income Risk. Current market conditions and the actions of governmental authorities and regulators in response to COVID-19 and its far-reaching effects present heightened risks to the fixed income market generally. Such risks could be further heightened if such market conditions become more volatile or the governmental and regulatory actions are unexpectedly or suddenly reversed or are ineffective in achieving their desired outcomes. In addition, the current environment is exposing fixed-income and debt markets to significant volatility and reduced liquidity for Fund investments.

◦Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund to decline. The Fund may be subject to a greater risk of rising interest rates due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives.

•Implied Volatility Risk. When the Fund sells an option, it gains the amount of the premium it receives, but also incurs a liability representing the value of the option it has sold until the option is either exercised and finishes “in the money,” meaning it has value and can be sold, or the option expires worthless, or the expiration of the option is “rolled,” or extended forward. The value of the options in which the Fund invests is based partly on the volatility used by market participants to price such options (i.e., implied volatility). Accordingly, increases in the implied volatility of such options will cause the value of such options to increase (even if the prices of the options’ underlying stocks do not change), which will result in a corresponding increase in the liabilities of the Fund under such options and thus decrease the Fund’s NAV.

◦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.

•Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. These factors include events impacting the entire market or specific market segments, such as political, market and economic developments, as well as events that impact specific issuers. The Fund’s NAV and market price, like security and commodity prices generally, may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time. U.S. and international markets have experienced significant periods of volatility in recent years due to a number of these factors, including the impact of the COVID-19 pandemic and related public health issues, growth concerns in the U.S. and overseas, uncertainties regarding interest rates, trade tensions and the threat of tariffs imposed by the U.S. and other countries. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, acts of terrorism, spread of infectious diseases or other public health issues, recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. These developments as well as other events could result in further market volatility and negatively affect financial asset prices, the liquidity of certain securities and the normal operations of securities exchanges and other markets. It is unknown how long circumstances related to the pandemic will persist, whether they will reoccur in the future, whether efforts to support the economy and financial markets will be

•Models and Data Risk. When models and data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data.

•New Fund Risk. The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision. Additionally, the Adviser has not previously managed a registered fund, which may increase the risks of investing in the Fund.

•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 lesser number of issuers than if it was a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a lesser number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

•Other Investment Company Risk. The risks of investment in other investment companies, including ETFs, typically reflect the risks of the types of instruments in which the investment companies invest. By investing in another investment company, the Fund becomes a shareholder of that investment company and bears its proportionate share of the fees and expenses of the other investment company. Investments in ETFs are also subject to the “ETF Risks” described above.

•Portfolio Turnover Risk. Because the Fund may “turn over” some or all of its portfolio frequently, the Fund may incur high levels of transaction costs from commissions or mark-ups in the bid/offer spread. Higher portfolio turnover (e.g., in excess of 100% per year) may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders.

•Tax Risk. The writing of options by the Fund may significantly reduce or eliminate its ability to make distributions eligible to be treated as qualified dividend income. Options entered into by the Fund may also be subject to the federal tax rules applicable to straddles under the Internal Revenue Code of 1986, as amended (the “Code”). If positions held by the Fund were treated as “straddles” for federal income tax purposes, or the Fund’s risk of loss with respect to a position was otherwise diminished as set forth in Treasury regulations, dividends on stocks that are a part of such positions would not constitute qualified dividend income subject to such favorable income tax treatment in the hands of non-corporate shareholders or eligible for the dividends received deduction for corporate shareholders. In addition, generally, straddles are subject to certain rules that may affect the amount, character and timing of the Fund’s recognition of gains and losses with respect to straddle positions. For more information, please see “ADDITIONAL INFORMATION ABOUT THE FUND – Principal Risks – Tax Risk” below and the section entitled “Federal Income Taxes” in the SAI.

•U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other fixed income securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. Treasury obligations to decline.

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. The difference in the bid and ask prices is referred to as the “bid-ask spread.”

The Fund’s distributions are generally taxable 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. Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.

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.
