Kingsbarn Tactical Bond ETF

Investment Objective

Kingsbarn Tactical Bond ETF (the “Fund”) seeks to maximize total return.

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. Investors purchasing shares on a national securities exchange, national securities association, or over-the-counter trading system where shares may trade from time to time (each, a “secondary market”) may be subject to customary brokerage commissions charged by their broker that 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⁾ Kingsbarn Capital Management, LLC (the “Adviser”) has contractually agreed to waive its management fee to an annual rate of 0.95% of the average daily net assets of the Fund until March 31, 2026 and the Adviser may not terminate this arrangement prior to that date.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then 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 effect of the Adviser’s agreement to waive a portion of its management fee is reflected in the example shown below for the first year. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year ended November 30, 2024, the Fund’s portfolio turnover rate was 0.00% of the average value of the portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing in a combination of exchange-traded funds (“ETFs”) focusing on fixed-income investments (“Underlying Bond Funds”) and futures contracts on 10-year U.S. Treasury notes (“10-Year Treasury Futures”). The Adviser will attempt to construct a diversified fixed income portfolio that will generally track the credit and duration risk of the Bloomberg Aggregate Bond Index. The Fund’s portfolio is selected by identifying Underlying Bond Funds focused on a range of fixed-income instruments that provide exposure to various credit qualities and issuers to enable the Fund to navigate a variety of market conditions. The Fund may hold one or more Underlying Bond Funds. The Advisor may tactically shift investment fixed income allocations in contrast to the Fund’s underlying Benchmark Index depending on the Adviser’s assessment of market conditions and the suitability of investment opportunities. Under normal circumstances, the Fund invests at least 80% of its net assets in bonds and other fixed-income securities through its investments in the Underlying Bond Funds.

The Adviser tactically manages the duration exposure of the Fund’s bond portfolio to generate excess returns. The management of the portfolio’s duration exposure is driven by a directional, short-term interest rate forecast by the Adviser which then drives the Adviser’s decisions to purchase or sell the 10-Year Treasury Futures for the Fund’s portfolio. As the Adviser’s interest rate outlook changes, the portfolio’s average duration is adjusted through the use of efficient and liquid 10-Year Treasury Futures to coincide with the Adviser’s directional interest rate forecast. When the Adviser expects interest rates to fall, the average duration of the portfolio will be lengthened in order to get the maximum benefit from that expected interest rate change. On the other hand, if the Adviser’s expects interest rates to rise, the portfolio’s average duration will be shortened to minimize the negative effect on the Underlying Bond Fund values. The forecasting process is systematic and utilizes multiple market based, economic and technical factors.

The Fund may invest in Underlying Bond Funds that that provide exposure to U.S. and international fixed-income securities, including emerging markets securities, of any maturity or duration. The Underlying Bond Funds may hold fixed-income securities of any credit quality, including below investment grade or “junk” bonds. The Fund may also invest in Underlying Bond Funds that, without limitation, purchase fixed-income securities in any sector and issued by companies, municipalities or government bodies of any size. The fixed-income securities in which the Underlying Bond Funds invest include corporate debt obligations, obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, municipal debt obligations, bank obligations, mortgage-related securities (including those that are issued on a when-issued or delayed delivery basis) and asset-backed securities, commercial paper, repurchase agreements, obligations of other domestic and foreign issuers, securities of domestic or foreign issuers denominated in U.S. dollars or in currencies other than the U.S. dollar, and obligations of supranational organizations. The Underlying Bond Funds may be index funds which means they seek to track the investment results of a particular index (a “target index”).

The Underlying Bond Funds may also purchase derivative instruments or engage in transactions in derivative transactions, including swaps, futures contracts and options on futures contracts. The Underlying Bond Funds will generally use the forgoing instruments to hedge against interest rate and/or credit risks. The Underlying Bond Funds may use forward foreign currency exchange contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. The Underlying Bond Funds may also lend their portfolio securities to generate additional income.

The Adviser may add new Underlying Bond Funds or replace or eliminate existing Underlying Bond Funds without notice or shareholder approval. The Fund may hold cash or invest in short-term paper and other short-term investments (instead of allocating investments to an Underlying Bond Fund) as deemed appropriate by the Adviser.

The Fund intends to operate as a “diversified” fund under both the rules and regulations of the 1940 Act and Sub-Chapter M of the Internal Revenue Code.

Principal Risks

As with all funds, a shareholder is subject to the risk that his or her investment could lose money. The principal risks affecting shareholders’ investments in the Fund are set forth below. An investment in the Fund is not a bank deposit and is

not insured or guaranteed by the FDIC or any government agency. The principal risks described herein pertain to direct risks of making an investment in the Fund and/or risks of the Underlying Bond Funds.

Market Risk. The market value of securities owned by the Fund may decline, at times sharply and unpredictably.

Active Management Risk. The Fund is subject to management risk as an actively-managed investment portfolio. The Adviser’s investment decisions about individual securities impact the Fund’s ability to achieve its investment objective. The Adviser’s judgments about the attractiveness and potential appreciation of particular investments in which the Fund invests may prove to be incorrect and there is no guarantee that the Adviser’s investment strategy will produce the desired results.

Other Investment Company Securities Risk. When the Fund invests in Underlying Bond Funds, it is subject to the risks associated with those investment companies, (such as the risk that the fund will be concentrated in a particular issuer, market, industry or sector, and therefore will be especially susceptible to loss due to adverse occurrences affecting that issuer, market, industry or sector). The Fund may be affected by losses of the Underlying Bond Funds and the level of risk arising from the investment practices of the Underlying Bond Funds (such as the use of derivative transactions by the Underlying Bond Funds). The ability of the Fund to meet its investment objective is affected by the ability of the Underlying Bond Funds to meet their investment objectives. The Fund has no control over the investments and related risks taken by the Underlying Bond Funds in which it invests. Underlying Bond Funds incur operating expenses that are separate from those of the Fund. As a result, the Fund’s shareholders will indirectly bear a proportionate share of the operating expenses of the Underlying Bond Funds, in addition to Fund expenses.

Fixed-Income Securities Risk. While fixed-income securities normally fluctuate less in price than stocks, there have been extended periods of increases in interest rates that have caused significant declines in fixed income securities prices. The values of fixed-income securities may be affected by changes in the credit rating or financial condition of their issuers. Generally, the lower the credit rating of a security, the higher the degree of risk as to the payment of interest and return of principal.

Credit Risk. The issuer of a fixed-income security may not be able to make interest and principal payments when due. Generally, the lower the credit rating of a security, the greater the risk that the issuer will default on its obligation.

Change in Rating Risk. If a rating agency gives a debt security a lower rating, the value of the debt security will decline because investors will demand a higher rate of return.

Interest Rate Risk. The value of the Fund may fluctuate based upon changes in interest rates and market conditions. As interest rates increase, the value of the Fund’s income-producing investments may go down. For example, bonds tend to decrease in value when interest rates rise. Debt obligations with longer maturities typically offer higher yields, but are subject to greater price movements as a result of interest rate changes than debt obligations with shorter maturities.

Duration Risk. Prices of fixed-income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities.

Prepayment Risk. Underlying Bond Funds in which the Fund invests may invest in mortgage- and asset-backed securities, which are subject to fluctuations in yield due to prepayment rates that may be faster or slower than expected.

Income Risk. The Fund’s income could decline due to falling market interest rates. In a falling interest rate environment, the Fund or an Underlying Bond Fund may invest its assets in lower-yielding securities. Because interest rates vary, it is impossible to predict the income or yield of the Fund or any Underlying Bond Fund for any particular period. In a falling interest rate environment, there may be lower-yielding securities.

High Yield (“Junk”) Bond Risk. 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. Junk bonds are generally less liquid than higher-quality securities. Many of these securities are not registered for sale under the federal securities laws and/or do not trade frequently. When they do trade, their prices may be significantly higher or lower than expected. At times, it may be difficult to sell these securities promptly at an acceptable price, which may limit the Underlying Bond Fund’s ability to sell securities in response to specific economic events or to meet redemption requests. As a result, certain high-yield debt instruments may pose greater illiquidity and valuation risks.

Derivatives Risk. The Fund will use derivative instruments such as futures contracts and the Underlying Bond Funds may use derivative instruments such as swaps, foreign currency exchange forward contracts, futures contracts and options on futures contracts. The value of derivatives may rise or fall more rapidly than other investments. For some derivatives, it is possible to lose more than the amount invested in the derivative. Other risks of investments in derivatives include imperfect correlation between the value of these instruments and the underlying assets; risks of default by the other party to the derivative transactions; risks that the transactions may result in losses that offset gains in portfolio positions; and risks that the derivative transactions may not be liquid. If the Fund or Underlying Bond Fund is not successful in employing such instruments in managing its portfolio, its performance will be worse than if it did not invest in such instruments. In utilizing certain derivatives, a fund’s losses are potentially unlimited. Derivative instruments may also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Underlying Bond Fund and the Fund.

Risk of Investing in Futures. The Fund will and the Underlying Bond Funds may invest in futures contracts. Futures contracts can be highly volatile and using futures can increase the volatility of a fund’s net asset value (“NAV”) and/or lower total return. Additionally, a relatively small movement in the price or value of a futures transaction may result in substantial losses to the fund, and the potential loss from futures can exceed the fund’s initial investment in such contracts. Futures contracts involve the risk of mispricing or improper valuation and the risk that changes in the value of a futures contract may not correlate perfectly with the underlying indicator. A liquid secondary market may not always exist for the futures contract positions held by the Fund or an Underlying Bond Fund at any time. While futures contracts are generally liquid instruments, under certain market conditions they may become illiquid. As a result, the Fund or an Underlying Bond Fund, may not be able to close out a position in a futures contract 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 can exceed the initial investment of the Fund or Underlying Bond Fund in such contracts. The use of derivatives by the Fund and Underlying Bond Funds may magnify losses for the Fund and the Underlying Bond Funds.

Swap Agreements Risk. An Underlying Bond Fund may use swap agreements. Swap agreements are contracts among a fund and a counterparty to exchange the return of the pre-determined underlying investment (such as the rate of return of a specified index). Swap agreements may be negotiated bilaterally and traded OTC between two parties or, in some instances, must be transacted

through a futures commission merchant and cleared through a clearinghouse that serves as a central counterparty. Risks associated with the use of swap agreements are different from those associated with ordinary portfolio securities transactions, due in part to the fact they could be considered illiquid and many swaps trade on the OTC market. Swaps are particularly subject to counterparty credit, correlation, valuation, liquidity and leveraging risks.

Leverage Risk. The Fund does not seek leveraged returns but, as a result of the use of certain derivatives by the Fund or the Underlying Bond Funds, investment leverage may be created. This means that the derivative position may provide the Fund or Underlying Bond Fund with investment exposure greater than the value of the investment of the Fund or the Underlying Bond Fund in the derivative. As a result, these derivatives may magnify losses to the Fund or Underlying Bond Fund, and even a small market movement may result in significant losses.

Liquidity Risk. The Fund is subject to liquidity risk primarily due to its investments in derivatives and the Underlying Bond Funds’ investments in junk bonds and swaps. Investments in illiquid assets involve the risk that the Fund or Underlying Bond Fund may be unable to sell such assets or sell them at a reasonable price.

Mortgage-Related Securities Risk. The Underlying Bond Funds may buy interests in pools of residential or commercial mortgages in the form of “pass-through” mortgage securities. The prices and yields of mortgage-related securities are determined, in part, by assumptions about the rate of payments of the underlying mortgages and are subject to the risks of unanticipated prepayment and extension risks. Mortgage-related securities are also subject to interest rate risk, and the market for mortgage-backed securities may be volatile at times and may be less liquid than the markets for other types of securities.

When-Issued and Delayed Delivery Transactions. Mortgage-related securities may be issued on a when-issued or delayed delivery basis, where payment and delivery take place at a future date. Because the market price of the security may fluctuate during the time before payment and delivery, the Underlying Bond Fund assumes the risk that the value of the security at delivery may be more or less than the purchase price.

Asset-Backed Securities Risk. The Underlying Bond Funds may buy interests in asset-backed securities which are fractional interests in pools of loans, receivables or other assets. They are issued by trusts or other special purpose vehicles and are collateralized by the loans, receivables or other assets that make up the pool. The trust or other issuer passes the income from the

underlying asset pool to the investor. Neither the Underlying Bond Fund nor its investment adviser selects the loans, receivables or other assets that are included in the pools or the collateral backing those pools. Asset-backed securities are subject to interest rate risk and credit risk. These securities are subject to the risk of default by the issuer as well as by the borrowers of the underlying loans in the pool. Certain asset-backed securities are subject to prepayment and extension risks.

Foreign Securities Risk. To the extent the Fund invests in in Underlying Bond Funds that invest in foreign securities, it may be subject to additional risks not typically associated with investments in domestic securities. These risks may include, among others, currency risk, country risks (political, diplomatic, regional conflicts, terrorism, war, social and economic instability, currency devaluations and policies that have the effect of limiting or restricting foreign investment or the movement of assets), different trading practices, less government supervision, less publicly available information, limited trading markets and greater volatility.

Risk of Investing in Emerging Markets. Investments in emerging market issuers may be subject to a greater risk of loss than investments in issuers located or operating in more developed markets. Emerging markets may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed markets. Companies in many emerging markets are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries, and as a result, information about the securities in which the Underlying Bond Funds invest may be less reliable or complete.

Currency Risk and Currency Hedging Risk. An Underlying Bond Fund may attempt to offset, or hedge, its foreign currency exposure by entering into currency hedging transactions, primarily through the use of foreign currency exchange forward contracts (a type of derivative). However, it generally is not possible for a fund to perfectly hedge its foreign currency exposure. In addition, the Underlying Bond Fund will incur expenses to hedge its foreign currency exposure. By entering into currency hedging transactions, the Underlying Bond Fund may eliminate any chance to benefit from favorable fluctuations in relevant currency exchange rates. An Underlying Bond Fund’s use of foreign currency exchange forward contracts also subjects the Fund to counterparty risk, which is the chance that the counterparty to a currency forward contract with the Underlying Bond Fund will be unable or unwilling to meet its financial obligations.

Sovereign and Quasi-Sovereign Obligations Risk. An Underlying Bond Fund may invest in securities issued by or guaranteed by non-U.S. sovereign governments and by entities affiliated with or backed by non-U.S. sovereign governments,

which may be unable or unwilling to repay principal or interest when due. In times of economic uncertainty, the prices of these securities may be more volatile than those of corporate debt obligations or of other government debt obligations.

Municipal Securities Risk. An Underlying Bond Fund may invest in municipal securities. Municipal securities can be significantly affected by political or economic changes, including changes made in the law after issuance of the securities, as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders, including in connection with an issuer insolvency. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the inability to collect revenues from such projects or assets. Certain municipal securities are issued by entities with limited taxing authority such as school districts, or dependent on revenue from a particular sector or industry, such as the utilities sector, infrastructure sector, or transportation industry.

ETF Structure Risk. The Fund and the Underlying Bond Funds are structured as ETFs and as a result are each subject to special risks. These risks may be magnified because they apply to the Fund and each Underlying Bond Fund the Fund holds. Such risks include:

•Trading Issues Risk. Trading in ETF shares on an exchange may be halted due to market conditions or for reasons that, in the view of the exchange, make trading in the ETF’s shares inadvisable, such as extraordinary market volatility. There can be no assurance that an ETF’s shares will continue to meet the listing requirements of its exchange or will trade with any volume. There is no guarantee that an active secondary market will develop for shares of an ETF. In stressed market conditions, the liquidity of shares of an ETF may begin to mirror the liquidity of the ETF’s underlying portfolio holdings, which can be significantly less liquid than shares of the ETF. This adverse effect on liquidity for the ETF’s shares in turn could lead to differences between the market price of the ETF’s shares and the underlying value of those shares.

•Market Price Variance Risk. The market prices of shares of an ETF will fluctuate in response to changes in the ETF’s NAV, and supply and demand for ETF shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that ETF shares may trade at a discount to NAV. The market price of an ETF’s shares may

deviate from the value of the ETF’s underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the shares of the ETF bought or sold.

• National Closed Market Trading Risk. To the extent that the underlying securities and/or other assets held by an ETF trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the ETF’s shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the ETF’s quote from the closed foreign market). These deviations could result in premiums or discounts to an ETF’s NAV that may be greater than those experienced by other ETFs.

• Authorized Participants (“APs”), Market Makers, and Liquidity Providers Risk. ETFs have 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 of an ETF 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.

• Costs of Buying or Selling Shares of an ETF. Due to the costs of buying or selling shares of an ETF, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of an ETF may significantly reduce investment results and an investment in shares of an ETF may not be advisable for investors who anticipate regularly making small investments.

Index-Related Risk. There is no guarantee that the Underlying Bond Fund’s investment results will have a high degree of correlation to those of its target index or that the Underlying Bond Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Underlying Bond Fund’s ability to adjust its exposure to the required levels in order to track the target index.

Securities Lending Risk. To the extent the Fund invests in Underlying Bond Funds that engage in securities lending, securities lending creates risk that the borrower may fail to return the securities in a timely manner or at all. As a result, the Underlying Bond Fund may lose money and there may be a delay in recovering the loaned securities. The Underlying Bond Fund could also lose money if it does not recover the securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences.

Investment Risk. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, as with any investment, you may lose some or all of your investment by investing in the Fund.

Performance History

Investment Adviser and Sub-Adviser

Kingsbarn Capital Management, LLC (the “Adviser”) is the investment adviser to the Fund.

Vident Asset Management (the “Sub-Adviser”) is the sub-adviser to the Fund.

Portfolio Manager

Steven Todd Ruoff, Managing Director of the Adviser, has served as the Fund’s portfolio manager since its inception in 2021.

Purchase and Sale of Fund Shares

The Fund will issue (or redeem) shares to certain institutional investors (typically market makers or other broker-dealers) only in large blocks of at least 10,000 shares known as “Creation Units.” Creation Unit transactions are typically conducted in exchange for the deposit or delivery of in-kind securities and/or cash. Individual shares may only be purchased and sold on a national securities exchange through a broker-dealer. You can purchase and sell individual shares of the Fund throughout the trading day like any publicly traded security. The Fund’s shares are listed on the NYSE Arca (the “Exchange”). The price of the

Fund’s shares is based on market price, and because ETF shares trade at market prices rather than NAV, Fund shares may trade at a price greater than NAV (premium) or less than NAV (discount). Except when aggregated in Creation Units, the Fund’s shares are not redeemable securities.

Tax Information

The Fund’s distributions will be taxed as ordinary income or capital gain, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account in which case withdrawals from such arrangements generally will be taxed.

Payments to Broker-Dealers and Other Financial Intermediaries

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