REX IncomeMax™ Option Strategy ETF

Investment Objective

The Fund's primary investment objective is to seek current income. The Fund's secondary investment objective is to seek exposure to the share price of select U.S.-listed securities, subject to a limit on potential investment gains.

Fees and Expenses of the Fund

The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund ("Fund Shares"). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.

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

Management Fees	1.25%
Distribution and Service (12b-1) Fees	0.00%
Other Expenses(1)	0.07%
Total Annual Fund Operating Expenses	1.32%

(1) "Other Expenses" are estimates based on the expenses the Fund expects to incur for the current fiscal year.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then hold or redeem all of your Fund 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 Fund Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$135	$420

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 total annual fund operating expenses or in the expense example above, affect the Fund's performance. During the fiscal period October 30, 2025 (commencement of operations) through December 31, 2025, the Fund's portfolio turnover rate was 1,253% of the average value of its portfolio.

Principal Investment Strategies

The Fund is an actively managed exchange-traded fund ("ETF") that seeks current income and exposure to the share price of select U.S.-listed securities, subject to a limit on potential investment gains. The Fund's strategy consists of the following elements: (1) constructing a portfolio of U.S.-listed equity securities (each, an "Underlying Security") (the "Equity Strategy"); and (2) generating income through an options portfolio (the "Options Strategy"), which includes options contracts on the Underlying Securities. The Fund may invest up to 10% of its total assets in cash or U.S. Treasury securities ("U.S. Treasuries"). REX Advisers, LLC (the "Adviser") serves as the Fund's investment adviser.

The Fund will seek to provide weekly income in the form of cash distributions by utilizing the following: (1) dividends received, if any, from direct investments in the Underlying Securities from its Equity Strategy; (2) premium income received from its Options Strategy; and (3) investing in short-term U.S. Treasuries.

Equity Strategy

The Fund will invest in Underlying Securities, which primarily include U.S.-listed common stocks. The Adviser employs a quantitative screening process, whereby the Adviser evaluates various factors, including the implied volatility of the Underlying Security, trading volume and liquidity of both the Underlying Security and options on the Underlying Security. Implied volatility is a measure of the market's expectation of future price movements of an underlying asset over the life of an option. Generally, the Adviser will seek to invest in Underlying Securities with higher implied volatility, which typically correlates to increased options premiums, allowing the Fund to generate income from its Options Strategy (described below). The Adviser also evaluates material forthcoming events relevant to the issuers of the Underlying Securities, such as scheduled earnings announcements, while also reviewing the trading activity and options contracts tied to such securities. Furthermore, as part of its risk management process in order to seek to lower risk and enhance returns, the Adviser will invest in Underlying Securities across various sectors and industries, reducing the impact of sector-specific events.

Under normal circumstances, the Fund will invest in Underlying Securities directly. However, from time to time, the Fund may invest in financial instruments, including options contracts, to provide synthetic exposure to the Underlying Securities. To provide synthetic exposure to the Underlying Securities, the Fund will use options contracts on Underlying Securities to gain exposure to the share price performance of the Underlying Securities. The allocation between direct and synthetic holdings varies based on strategic decisions and market conditions as assessed by the Adviser. However, the Fund will primarily use synthetic covered Options Strategies. When the Adviser determines it to be more cost-effective, the Fund may directly hold Underlying Securities.

To achieve synthetic exposure to an Underlying Security, the Fund may purchase that Underlying Security's call options and, simultaneously, sell that Underlying Security's put options to attempt to replicate the price movements of owning such Underlying Security. The call options purchased by the Fund and the put options sold by the Fund will generally have 1-month to 6-month terms and strike prices that are approximately equal to the then-current share price of the relevant Underlying Security at the time the options contracts are purchased and sold, respectively. The combination of the purchased call options and sold put options provides the Fund with investment exposure equal to approximately 100% of the relevant Underlying Securities for the duration of the applicable options exposure.

The Adviser will typically select between 15-30 Underlying Securities and will implement its Options Strategy on the Underlying Securities. However, when the Adviser deems it appropriate, it may choose as few as five Underlying Securities on which to implement its Options Strategy.

Options Strategy

The Fund seeks to generate income from its Options Strategy by primarily utilizing options contracts on its Underlying Securities. The Fund's Options Strategy is applied consistently, regardless of whether the Underlying Security is held directly or through synthetic exposure.

The financial instruments in which the Fund enters into will primarily be through options contracts, including standardized exchange-traded and FLexible EXchange^® Options ("FLEX Options"). All options in which the Fund invests are exchange-traded and are guaranteed for settlement by the Options Clearing Corporation ("OCC").

In general, an options contract gives the purchaser of the options contract the right to purchase (for a call option) or sell (for a put option) the underlying asset at a specified price (the "strike price"). If exercised, an options contract obligates the seller to deliver shares (for a sold call option) or buy shares (for a sold put option) of the underlying asset at the strike price. The purchaser of the options contract pays the option seller for the rights granted by the option (this is referred to as the "premium"). Options contracts must be exercised or traded to close within a specified time frame or they expire. Standardized exchange-traded options have standard terms, such as the type, reference asset, strike price and expiration date. FLEX Options are a type of exchange-listed options contract with uniquely customizable terms that allow investors to customize key terms like type, strike price and expiration date that are standardized in a typical options contract. An options contract is said to be "European Style" when it can be exercised only at its expiration, whereas an "American Style" options contract can be exercised at any time prior to its expiration. The Fund may utilize both European and American style options contracts.

As part of its Options Strategy, the Fund may generate income in the form of a premium by simultaneously writing (selling) options contracts on a portion of the Equity Strategy portfolio. A premium, in this context, refers to the price the option buyer pays to the option seller (the Fund) for the rights granted by the option. Due to the Fund's Options Strategy, the sale of options to generate income may limit the Fund's ability to participate in increases in value of the Underlying Securities' share price beyond a certain point. For example, if the Underlying Securities' share price appreciates beyond the strike price of one or more of its sold options contracts, the Fund will lose money on those sold positions, and the losses will, in turn, limit the upside return of the Fund's equity exposure. As a result, the Fund's Options Strategy may limit the Fund's participation in gains in the price performance of the Underlying Securities. Nevertheless, the Fund will not sell (write) an option unless, at the same time, it purchases another option with a lower delta on the same Underlying Security. This strategy is intended to limit the potential risk associated with selling options contracts by ensuring that the Fund holds an offsetting position that can help mitigate losses if the market moves unfavorably. "Delta" is a measure of how much an option contract's price is expected to change when the price of the underlying reference asset changes. An option with a lower delta is less sensitive to changes in the price of the underlying reference asset.

The Fund may utilize a call spread strategy whereby the Fund will enter into call spread options contracts on the Underlying Securities from which the Fund will receive a premium. The Fund may write (sell) call spreads rather than standalone call options contracts to seek greater participation in the potential appreciation of the Underlying Securities' share price, while still generating premium income. A call spread is established by selling a call options contract while simultaneously purchasing a call options contract with the same maturity but at a higher strike price. The Fund's upside participation in any potential increase in the price return of the Underlying Securities is capped at the strike price of the call options contract purchased by the Fund. The combined position is designed to allow the Fund to retain premium income while limiting downside exposure to losses above the strike price of the sold call options and capping upside exposure of the Underlying Securities above the strike price of the purchased call options.

The Fund may also utilize a put write strategy whereby the Fund will write (sell) put options contracts on the Underlying Securities from which the Fund will receive a premium. The position is designed to generate income for the Fund through the receipt of premiums; however, the Fund will be exposed to the risk of loss if the price of the Underlying Security falls below the strike price of the sold put options.

The Adviser will implement its Options Strategy in various market conditions. Depending on the market outlook, the Adviser will select one Options Strategy or a combination of Options Strategies that it believes will best provide the Fund with current income while also generally attempting to provide upside appreciation. The Adviser will adjust the portfolio as necessary to appropriately size positions in response to capital inflows and outflows, ensuring that the Fund's holdings remain consistent with its investment strategies.

The Adviser also evaluates the performance of each Underlying Security. When the Adviser expects an Underlying Security's value to appreciate, the Options Strategy is structured to capture additional capital appreciation. Conversely, if the Adviser anticipates a decline in the Underlying Security's value, the Options Strategy is designed to mitigate potential losses. If the Adviser determines that options on a particular Underlying Security are illiquid, excessively costly, or otherwise unsuitable, the Adviser may instead employ an Options Strategy using options on an ETF that serves as an alternative for that Underlying Security. Although these alternative ETFs may not be the Fund's targeted Underlying Securities, each qualifies as an eligible Underlying Security under the Fund's investment strategy. The Fund's Options Strategy that utilizes such alternative ETFs will be fully covered, meaning the Fund will hold shares of the corresponding ETF when it utilizes options contracts.

The Fund may be subject to different outcomes depending on the Options Strategy utilized by the Adviser. The specific Options Strategy utilized by the Adviser may impact the risk-return profile of the Fund, potentially affecting volatility, income generation, gain potential, and capital preservation.

Additionally, the premiums the Fund receives from selling options contracts are directly influenced by market volatility (i.e., higher market volatility typically results in higher premiums). Therefore, the Adviser analyzes market conditions to determine the timing and type of the Options Strategy to employ to achieve the Fund's primary objective of current income. By strategically entering and exiting options positions, the Adviser seeks to enhance the Fund's income potential.

U.S. Treasuries

The Fund may hold cash, cash equivalents and other short-term investments, including U.S. Treasuries (including bills, notes and bonds) and money market funds. These securities provide collateral for the Fund's Options Strategy and contribute to the Fund's income generation.

The Fund is classified as "non-diversified" under the Investment Company Act of 1940, as amended (the "1940 Act").

There is no guarantee that the Fund's investment strategy will be properly implemented, and an investor may lose some or all of its investment.

Principal Risks

As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Each risk summarized below is considered a principal risk of investing in the Fund, regardless of the order in which it appears. The significance of each risk factor below may change over time and you should review each risk factor carefully.

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser makes for the Fund. In managing the Fund's investment portfolio, the portfolio managers will apply investment techniques and risk analyses, including through the use of technology, automated processes, algorithms, or other management systems, that may not operate as intended or produce the desired result. 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.

AUTHORIZED PARTICIPANTS, MARKET MAKERS, AND LIQUIDITY PROVIDERS LIMITATION RISK. The Fund has a limited number of financial institutions that may act as Authorized Participants ("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, Fund 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 TRANSACTIONS RISK. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund's NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund's NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund's performance could be negatively impacted.

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared ("cleared derivatives"). In a transaction involving cleared derivatives, the Fund's counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse ("clearing members") can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard to its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy.

COSTS OF BUYING AND SELLING FUND SHARES RISK. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

COUNTERPARTY RISK. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (cleared derivatives). In a transaction involving cleared derivatives, the Fund's counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (clearing members) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing members' individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing members' bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing members' customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing members' default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy.

Cyber security Risk. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund's digital information systems through "hacking" or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund's third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

DEBT SECURITIES RISK. The Fund will invest in various types of debt securities, which may be used for collateral for the Fund's options contracts and/or swap agreements and may be used to generate additional income. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

DERIVATIVES RISK. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund's investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund's other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the value of the underlying instrument and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund's investments in derivatives are subject to the following risks:

OPTIONS CONTRACTS RISK. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political events, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the options contract and economic events. For the Fund in particular, the values of the options contracts in which it invests are substantially influenced by the values of the underlying instruments. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund will enter into new options contracts, a practice referred to as rolling.

DISTRIBUTION RISK. As part of the Fund's investment objectives, the Fund seeks to provide current income. There is no assurance that the Fund will make a distribution at any given time. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the distributions, if any, may consist of returns of capital, which would decrease the Fund's NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a regular basis. While the Fund will normally pay its income as distributions, the Fund's distributions may exceed the Fund's income and gains for the Fund's taxable year. The Fund may be required to reduce its distributions if it has insufficient income. Additionally, there may be times the Fund needs to sell securities when it would not otherwise do so and could cause the distributions from that sale to constitute return of capital. Distributions in excess of the Fund's current and accumulated earnings and profits will be treated as a return of capital. Return of capital distributions do not represent income or gains generated by the Fund's investment activities and should not be interpreted by shareholders as such. Distributions in excess of the Fund's minimum distribution requirements, but not in excess of the Fund's earnings and profits, will be taxable to Fund shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be currently taxable but will reduce the shareholder's cost basis and will result in a higher capital gain or lower capital loss when those Fund shares on which the distribution was received are sold. Once a Fund shareholder's cost basis is reduced to zero, further distributions (in excess of earnings and profits) will be treated as capital gain, if the Fund shareholder holds shares of the Fund as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because the Fund's distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

DIVIDEND RISK. There is no guarantee that the issuers of the Fund's portfolio securities will declare dividends in the future or that, if declared, they will either remain at current levels or increase over time.

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders' claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund's ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

HIGH PORTFOLIO TURNOVER RISK. The Fund may actively and frequently trade all or a significant portion of the Fund's holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund's expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund's assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security's price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security's expected life on a present value basis, taking into account the debt security's yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

LEVERAGE RISK. The Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund's portfolio securities. Derivative instruments involve a degree of leverage and as a result, a relatively small price movement in derivative instruments may result in immediate and substantial losses to the Fund.

LIQUIDITY RISK. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

market maker Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares due to a limited number of market makers. Decisions by market makers or authorized participants 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 Share price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund 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 Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a discount to NAV and also in greater than normal intraday bid-ask spreads for Fund Shares.

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their NAV, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

MONEY MARKET/SHORT-TERM SECURITIES RISK. To the extent that the Fund invests in money market or short-term securities, the Fund may be subject to certain risks associated with such investments. An investment in a money market fund or short-term securities is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. It is possible for the Fund to lose money by investing in money market funds. A money market fund may not achieve its investment objective. Changes in government regulations may affect the value of an investment in a money market fund.

NEW FUND RISK. The Fund is a recently organized management investment company with limited operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions.

NON-DIVERSIFICATION RISK. The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund's service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund's ability to meet its investment objective. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

PREMIUM/DISCOUNT RISK. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Fund Shares will approximate the Fund's NAV, there may be times when the market price of Fund Shares is more than the NAV intraday (premium) or less than the NAV intraday (discount) due to supply and demand of Fund Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund's portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Fund Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Fund Shares at a time when the market price is at a premium to the NAV of Fund Shares or sells at a time when the market price is at a discount to the NAV of Fund Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

PRICE PARTICIPATION RISK. The Fund employs an investment strategy that includes the sale of call options contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying Securities. This means that if the Underlying Securities experience an increase in value above the strike price of the sold call options, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying Securities. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying Securities, but has full exposure to any decreases in value experienced by the Underlying Securities, the NAV of the Fund may decrease over any given time period. The Fund's NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying Securities. The degree of participation in the Underlying Securities' gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold call options contracts and will vary over time. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying Securities, changes in interest rates, changes in the actual or perceived volatility of the Underlying Securities and the remaining time to the options' expiration, as well as trading conditions in the options market. As the price of the Underlying Securities changes and time moves towards the options contract's expiration date, the value of the options contracts, and therefore the Fund's NAV, will change. However, it is not expected for the Fund's NAV to directly correlate on a day-to-day basis with the returns of the Underlying Securities. The amount of time remaining until the options contract's expiration date affects the impact of the potential options contract income on the Fund's NAV, which may not be in full effect until the expiration date of the Fund's options contracts. Therefore, while changes in the price of the Underlying Securities will result in changes to the Fund's NAV, the Fund generally anticipates that the rate of change in the Fund's NAV will be different than that experienced by the Underlying Securities.

SMALL AND/OR MID CAPITALIZATION COMPANIES RISK. Small and/or mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than large capitalization companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than large capitalization companies.

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company ("RIC") under the Code. To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things: (i) in each taxable year, derive at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its portfolio holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund's assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund's total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships (the "Diversification Tests"); and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify as a RIC if the failure is for reasonable cause, or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

The Fund intends to enter into financial instruments on the Underlying Security. At least quarterly, the Fund will need to meet the Diversification Tests to maintain its RIC status. This may require selling some financial instruments referencing the Underlying Security in order to purchase other assets that meet the Diversification Tests. Such sales and purchases could affect the investment return of the Fund and may require the Fund to make distributions that were not otherwise required.

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund's performance.

TRADING ISSUES RISK. Although Fund Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund's underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. 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. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including "fair valued" assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund's ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Performance

As of the date of this prospectus, the Fund has been in operation for less than one full calendar year and therefore does not report its performance information. Once available, the Fund's performance information will be accessible on the Fund's website at https://www.rexshares.com/ulti and will provide some indication of the risks of investing in the Fund.

Management

Investment Adviser: REX Advisers, LLC (the "Adviser") is the investment adviser to the Fund.

Portfolio Managers: The individuals primarily responsible for the day-to-day management of the Fund are Matthew Pelletier and Matthew Holcomb. Each has served as a portfolio manager since the Fund's inception in 2025.

Purchase and Sale of Fund Shares

The Fund will issue (or redeem) Fund Shares to certain institutional investors (typically market makers or other broker-dealers) only in large blocks of Fund Shares known as "Creation Units." Creation Unit transactions are conducted in exchange for the deposit or delivery of a designated portfolio of in-kind securities and/or cash.

Individual Fund Shares may only be purchased and sold on the Exchange, other national securities exchanges, electronic crossing networks and other alternative trading systems through your broker-dealer at market prices. Because Fund Shares trade at market prices rather than at NAV, Fund Shares may trade at a price greater than NAV (premium) or less than NAV (discount). When buying or selling Fund Shares in the secondary market, you may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Fund Shares (bid) and the lowest price a seller is willing to accept for Fund Shares (ask) (the "bid-ask spread"). Recent information regarding the Fund's NAV, market price, premiums and discounts, and bid-ask spreads is available at https://www.rexshares.com/ulti.

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 will be taxed.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Fund Shares through a broker-dealer or other financial intermediary (such as a bank), the Adviser and the Fund's distributor 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 intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
