FUND SUMMARY – Main Sector Rotation ETF 

Investment Objective: Main Sector Rotation ETF (“the Fund”) seeks to outperform the S&P 500 in rising markets while limiting losses during periods of decline.

Fees and Expenses of the Fund: This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Shares”). 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.

Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual 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. Although your actual costs may be higher or lower, based upon 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 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 fiscal year ended October 31, 2022, the Fund’s portfolio turnover rate was 48% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES: The Fund utilizes a “fund of funds” structure to invest in sector-based equity exchange traded funds (“ETFs”). The Fund seeks to achieve its objective through dynamic sector rotation. The Fund’s adviser, Main Management ETF Advisors, LLC (the “Adviser”), focuses its research primarily on sector selection by carefully reviewing the sectors, industries, and sub-industries in the Fund’s portfolio. The Adviser chooses sectors it believes are undervalued and poised to respond favorably to financial market catalysts. The Fund sells a security when it achieves its target price and is, in the opinion of the Adviser, no longer undervalued. The Fund may overweight or underweight a sector or sectors relative to the Fund’s benchmark based on valuation. The Fund may invest in securities of any market capitalization or country and denominated in any currency.

The Fund is an actively managed ETF and does not seek to replicate the performance of a specified index. In selecting investments for the Fund’s portfolio, the Adviser adheres to the investment process described below.

Assessing Market Conditions. The Adviser determines the Fund’s target sector allocations by analyzing market sectors and their underlying industries and sub-industries. The Adviser uses the Global Industry Classification Standard (“GICS”) in its sector analysis. GICS sectors include: energy, materials, industrials, consumer discretionary, consumer staples, healthcare, financials, information technology, communication services, utilities, and real estate. The Adviser analyzes economic growth forecasts, inflation trends, and other macroeconomic and capital market fundamentals over a 6-18 month time horizon. The Adviser identifies opportunities for near-term growth in value that are facilitated by events or changes within sectors that its research has identified as “undervalued.”

Identifying the Appropriate ETFs. The Adviser then seeks to identify the most appropriate U.S. Sector ETFs to implement its strategic asset allocation and sector views by evaluating various factors in the respective ETFs including their respective underlying indexes and portfolio holdings, sector exposure and weightings, liquidity profiles, and tracking error.

Option Strategy. The Fund may from time to time incorporate a covered call option writing strategy. Covered call option writing is an investment strategy of writing (selling) call options against securities owned by the Fund to generate additional returns from the option premium. The Fund may also seek returns by writing (selling) secured put options. A “put option” is an option contract that gives the owner the right to sell the underlying security at a specified price (the strike price) until its expiration at a fixed date in the future. The Fund seeks to achieve risk-adjusted returns through targeted allocations by analyzing interest and currency rates, inflation trends, economic growth forecasts, and other global and capital market fundamentals. The Fund’s option strategy may also have the benefit of reducing the volatility of the Fund’s portfolio in comparison to that of broad equity market indexes.

The Fund pursues its options strategy by writing (selling) covered call or index-based options on an amount from 0% to 100% of the value of the ETF shares in the Fund’s portfolio. The Fund seeks to earn income and gains both from dividends paid on the ETFs owned by the Fund and cash premiums received from writing or “selling”:

The Fund may not sell “naked” put or call options, i.e., equity options representing more shares of an ETF than the Fund has cash on hand and available to purchase or index options greater than the value of the underlying security. Stock index options are put options and call options on various stock indices. The primary difference between stock options and index options occurs when index options are exercised. In the case of stock options, the underlying security, common stock, is delivered. However, upon the exercise of an index option, settlement does not occur by delivery of the securities comprising the index. The option holder exercising the index option receives an amount of cash if the closing level of the stock index upon which the option is based is greater than, in the case of a call, or less than, in the case of a put, the exercise price of the option. This amount of cash is equal to the difference between the closing price of the stock index and the exercise price of the option expressed in dollars times a specified multiple. A stock index fluctuates with changes in the market value of the stocks included in the index. A call option on a security is a contract that gives the holder of the option, in return for a premium, the right, but not the obligation, to buy from the writer of the option the security underlying the option at a specified exercise or “strike” price by or before the contract’s expiration. A put option on a security is a contract that gives the holder of the option, in return for a premium, the right to sell to the writer of the option the security underlying the option at a specified exercise or “strike” price. The writer of an option on a security has the obligation upon exercise of the option to purchase the underlying security at the exercise price.

Principal Investment Risks: As with all funds, there is a risk that you could lose money through your investment in the Fund. Many factors affect the Fund’s net asset value and price of shares and performance.

The following describes the risks of investing in the Fund. As with any ETF, there is no guarantee that the Fund will achieve its goal.

Allocation Risk. If the Fund’s strategy for allocating assets among different sectors and sub sectors does not work as intended, the Fund may not achieve its objective or may underperform other funds with the same or similar investment strategy.

Authorized Participant Risk. Only an Authorized Participant that has entered into a contractual arrangement with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. The Fund’s distributor has entered into contracts with only a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem large blocks of Shares known as “Creation Units,” Shares may be more likely to trade at a premium or discount to net asset value (“NAV”) and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs that invest in non-U.S. securities or other securities or instruments that have lower trading volumes.

Covered Call Risk. The writer of a covered call option forgoes any profit from increases in the market value of the underlying security covering the call option above the sum of the premium and the strike price of the call but retains the risk of loss if the underlying security declines in value. The Fund has no control over the exercise of the option by the option holder and may lose the benefit from any capital appreciation on the underlying security.

Currency Risk. Investments in foreign currencies are subject to political and economic risks, civil conflicts and war and greater volatility. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, imposition of currency controls and economic or political developments in the U.S. or abroad.

Derivatives Risk. The Fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Exchange-Traded Fund Risk. The ETFs in which the Fund invests will not be able to replicate exactly the performance of the indices they track because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. This may result in a loss. Certain securities comprising the indices tracked by the ETFs may, from time to time, temporarily be unavailable, which may further impede the ETFs’ ability to track their applicable indices. ETFs in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the ETFs will be higher than the cost of investing directly in the ETFs underlying investments and may be higher than other mutual funds that invest directly in stocks and bonds. ETFs may also trade at a discount or premium to their net asset value.

ETF Structure Risk. The Fund is structured as an ETF and as a result is subject to special risks, including:

o    The market price for Shares may deviate from the Fund’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Shares than the Fund’s NAV, which is reflected in the bid and ask price for Shares or in the closing price.

Equity Risk. Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The equity securities held by the Fund may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors affecting securities markets generally, the equity securities of a particular sector, or a particular company.

Fluctuation of Net Asset Value Risk. The NAV of Shares generally fluctuates with changes in the market value of the Fund’s holdings. The market prices of Shares generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for the shares on the Exchange. The Adviser cannot predict whether Shares will trade below, at or above their NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for the shares will be closely related to, but not identical to, the same forces influencing the prices of the Fund’s holdings trading individually or in the aggregate at any point in time. In addition, unlike conventional ETFs, the Fund is not an index fund. The Fund is actively managed and does not seek to replicate the performance of a specified index. Index based ETFs have generally traded at prices which closely correspond to NAV per share. Actively managed ETFs have a limited trading history and, therefore, there can be no assurance as to whether and/or the extent to which Shares will trade at premiums or discounts to NAV.

Foreign Securities Risk. Foreign companies are generally not subject to the same regulatory requirements of U.S. companies thereby resulting in less publicly available information about these companies. In addition, foreign accounting, auditing and financial reporting standards generally differ from those applicable to U.S. companies.

Index Call Option Risk. Because the exercise of index options is settled in cash, sellers of index call options, such as the Fund, cannot provide in advance for their potential settlement obligations by acquiring and holding the underlying securities. The Fund bears a risk that the value of the securities held by the Fund will vary from the value of the index and relative to the written index call option positions. Accordingly, the Fund may incur losses on the index call options that it has sold that exceed gains on other securities in its portfolio. The value of index options written by the Fund, which are priced daily, are affected by changes in the value of and dividend rates of the underlying common stocks in the index, changes in the actual or perceived volatility of the stock market and the remaining time to the options’ expiration. The value of the index options also may be adversely affected if the market for the index options becomes less liquid or smaller.

Large Capitalization Securities Risk. The value of investments in larger companies may not rise as much as smaller companies, or larger companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.

Management Risk. The portfolio managers’ judgments about the attractiveness, value and potential appreciation of particular stocks or other securities in which the Fund invests may prove to be incorrect and there is no guarantee that the portfolio managers’ judgment will produce the desired results.

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate-change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets.

Sector Risk. The Fund may have significant exposure to a limited number of issuers conducting business in the same sector or group of sectors. Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single sector or a group of sectors, and the securities of companies in that sector or group of sectors could react similarly to these or other developments. If the Fund invests more heavily in a particular sector, the value Shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, Share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of sectors. Additionally, some sectors could be subject to greater government regulation than other sectors. Therefore, changes in regulatory policies for those sectors may have a material effect on the value of securities issued by companies in those sectors.

Small and Medium Capitalization Securities Risk. The earnings and prospects of small and medium sized companies are more volatile than larger companies and may experience higher failure rates than larger companies. Small and medium sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures and may have limited markets, product lines, or financial resources and lack management experience.

Performance: The bar chart and performance table below show the variability of the Fund’s returns, which is some indication of the risks of investing in the Fund. The bar chart shows performance of the Fund’s shares for each calendar year since the Fund’s inception. The performance table compares the performance of the Fund over time to the performance of a broad-based securities market index.

The S&P 500 Total Return Index (the “Index”) is an unmanaged free-float capitalization-weighted index which measures the performance of 500 large-cap common stocks actively traded in the United States. Index returns assume reinvestment of dividends. Investors may not invest in the Index directly; unlike the Fund’s returns, the Index does not reflect any fees or expenses.

Investment Adviser: Main Management ETF Advisors, LLC

Portfolio Managers: Kim D. Arthur, Chief Executive Officer of the Adviser, James W. Concidine, Chief Risk Officer of the Adviser, and J. Richard Fredericks, Managing Director of the Adviser, have served the Fund as portfolio managers since it commenced operations in 2017. Alex Varner, Director of Research of the Adviser, has served the Fund as a portfolio manager since December 2021.

Purchase and Sale of Fund Shares: Individual Shares of the Fund may be purchased and sold in secondary market transactions through a broker dealer or at market price. Shares are listed for trading on the Exchange and trade at market prices rather than NAV. Shares may trade at a price that is greater than, at, or less than NAV. An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares on the secondary market (the “bid-ask spread”). Information on the Fund’s net asset value, market price, premiums and discounts and bid-ask spreads is available at www.mainmgtetfs.com.

Shares are listed for trading on the Exchange and trade at market prices rather than NAV. Shares may trade at a price that is greater than, at, or less than NAV.

Tax Information: Dividends and capital gain distributions you receive from the Fund, whether you reinvest your distributions in additional Fund shares or receive them in cash, are taxable to you at either ordinary income or capital gains tax rates unless you are investing through a tax-deferred plan such as an IRA or 401(k) plan. However, these dividend and capital gain distributions may be taxable upon their eventual withdrawal from tax-deferred plans.

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

FUND SUMMARY – Main Thematic Innovation ETF 

Investment Objective: Main Thematic Innovation ETF (“the Fund”) seeks to outperform the MSCI ACWI Index® in rising markets while limiting losses during periods of decline.

Fees and Expenses of the Fund: This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund (“Shares”). 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.

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. Although your actual costs may be higher or lower, based upon 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 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 fiscal year ended October 31, 2022, the Fund’s portfolio turnover rate was 43% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES: The Fund utilizes a “fund of funds” structure to invest in theme-based equity exchange traded funds (“ETFs”). The Fund seeks to achieve its objective through dynamic thematic rotation. The Fund’s adviser, Main Management ETF Advisors, LLC (the “Adviser”), focuses its research primarily on identifying emerging, disruptive, and innovative themes that have a large market demand or “addressable market.” The Adviser rotates among themes with large addressable markets which may range from nascent technologies to those on the cusp of widespread adoption and buys securities of ETFs investing in those themes.

As seen from past disruptive technologies, the market often does not initially price a theme appropriately, or even for several years, as the market’s response to the theme is often underestimated. Disruptors must continually reinvest in their future and expand their reach as they grow and these moves are hard for markets to accurately price, resulting in the potential for appreciation.

The portfolio managers set price targets for each position and revisit a position when the price target is met, revising upwards when deemed appropriate or selling when the investment committee concludes the theme has either run its course or is no longer likely to provide further exposure to growth, disruption, or innovation. Looking for themes with large market demand may mean price targets are revised upwards multiple times. The holding period is long-term as it may take years or even decades for themes to realize their full potential.

The Adviser rebalances the Fund’s portfolio when the investment committee deems appropriate. Given the longer-term nature of thematic development, an automatic monthly or quarterly rebalancing policy could be counterproductive to the Fund’s objective of seeking maximum return. From time to time, the Fund may use a covered call or covered put option strategy in an attempt to dampen volatility and generate additional returns.

The Fund is an actively managed ETF and does not seek to replicate the performance of a specified index. In selecting investments for the Fund’s portfolio, the Adviser adheres to the investment process described below.

Assessing Market Conditions. The Adviser determines the Fund’s target allocations by analyzing developing and ongoing technological and behavioral themes and their underlying addressable markets. The Adviser identifies themes consisting of securities in the aggregate that are poised for significant growth, disruption, or innovation. To identify such themes, the Adviser analyzes economic growth forecasts, changes in the factors driving growth, behavioral patterns among consumers, as well as other macroeconomic fundamentals. Themes may include: genomics, fintech, e-commerce, robotics, artificial intelligence, cyber security, clean energy, cloud computing, autonomous tech, gaming & e-sports, and pet care. The Adviser identifies themes that have large addressable markets and may be still early in their life cycle. In addition, the Adviser considers fundamental factors such as Price to Growth, Price to Earnings, Price to Book, and Price to Sales. The growth rate and size of the addressable market are the primary metrics of consideration.

Identifying the Appropriate ETFs. The Adviser then seeks to identify 5-15 theme-based ETFs to implement its strategic asset allocation and thematic views by evaluating various factors in the respective ETFs including their respective underlying indexes and portfolio holdings, sector exposure and weightings, liquidity profiles, and tracking error. At any given time, the Fund may have a significant percentage of its assets invested in one or more sectors than other sectors.

Option Strategy. The Fund may from time to time incorporate a covered call option writing strategy. Covered call option writing is an investment strategy of writing (selling) call options against securities owned by the Fund to generate additional returns from the option premium. The Fund may also seek returns by writing (selling) secured put options. The Fund may seek to hedge downside risk by purchasing protective puts. A “put option” is an option contract that gives the owner the right to sell the underlying security at a specified price (the strike price) until its expiration at a fixed date in the future. The Fund seeks to achieve risk-adjusted returns through targeted allocations by analyzing interest and currency rates, inflation trends, economic growth forecasts, and other global and capital market fundamentals. The Fund’s option strategy may also have the benefit of reducing the volatility of the Fund’s portfolio in comparison to that of broad equity market indexes.

Principal Investment Risks: As with all funds, there is a risk that you could lose money through your investment in the Fund. Many factors affect the Fund’s net asset value and price of shares and performance.

The following describes the risks of investing in the Fund. As with any ETF, there is no guarantee that the Fund will achieve its goal.

Allocation Risk. If the Fund’s strategy for allocating assets among different sectors and sub sectors does not work as intended, the Fund may not achieve its objective or may underperform other funds with the same or similar investment strategy.

Authorized Participant Risk. Only an Authorized Participant that has entered into a contractual arrangement with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. The Fund’s distributor has entered into contracts with only a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem large blocks of Shares known as “Creation Units,” Shares may be more likely to trade at a premium or discount to net asset value (“NAV”) and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs that invest in non-U.S. securities or other securities or instruments that have lower trading volumes.

Covered Call Risk. The writer of a covered call option forgoes any profit from increases in the market value of the underlying security covering the call option above the sum of the premium and the strike price of the call but retains the risk of loss if the underlying security declines in value. The Fund has no control over the exercise of the option by the option holder and may lose the benefit from any capital appreciation on the underlying security.

Currency Risk. Investments in foreign currencies are subject to political and economic risks, civil conflicts and war and greater volatility. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, imposition of currency controls and economic or political developments in the U.S. or abroad.

Derivatives Risk. The Fund’s use of options involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and
(iii) the risk that changes in the value of an option may not correlate perfectly with the underlying asset, rate or index. Derivative prices may be highly volatile at times and may fluctuate substantially during a short period of time.

o    Options Risk. There are risks associated with the sale and purchase of call and put options. As a seller (writer) of a put option, the Fund will tend to lose money if the value of the reference index or security falls below the strike price. As the seller (writer) of a call option, the Fund may experience lower returns if the value of the reference index or security rises above the strike price.

o    Put Option Risk. Options may be subject to volatile swings in price influenced by changes in the value of the underlying instrument. Although the Fund collects premiums on the options it writes, the Fund’s risk of loss if its options expire in-the-money (i.e., the Fund, as the seller of puts, owes the buyer of the puts) may outweigh the gains to the Fund from the receipt of such option premiums. The potential return to the Fund is limited to the amount of option premiums it receives; however, the Fund can potentially lose up to the entire strike price of each option it sells. The puts sold by the Fund may not perfectly correlate with the returns of their underlying stocks.

Exchange-Traded Fund Risk. The ETFs in which the Fund invests will not be able to replicate exactly the performance of the indices they track because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. This may result in a loss. Certain securities comprising the indices tracked by the ETFs may, from time to time, temporarily be unavailable, which may further impede the ETFs’ ability to track their applicable indices. ETFs in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the ETFs will be higher than the cost of investing directly in the ETFs underlying investments and may be higher than other mutual funds that invest directly in stocks and bonds. ETFs may also trade at a discount or premium to their net asset value.

ETF Structure Risk. The Fund is structured as an ETF and as a result is subject to special risks, including:

• Not Individually Redeemable. Shares are not individually redeemable to retail investors and may be redeemed by the Fund only to Authorized Participants at NAV in Creation Units. An Authorized Participant may incur brokerage costs purchasing enough Shares to constitute a Creation Unit.
• Trading Issues. An active trading market for Shares may not be developed or maintained. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility.
• Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for 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 Shares may trade at a discount to NAV.
  • The market price for Shares may deviate from the Fund’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Shares than the Fund’s NAV, which is reflected in the bid and ask price for Shares or in the closing price.

Equity Risk. Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The equity securities held by the Fund may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors affecting securities markets generally, the equity securities of a particular sector, or a particular company.

Fluctuation of Net Asset Value Risk. The NAV of Shares generally fluctuates with changes in the market value of the Fund’s holdings. The market prices of Shares generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for the shares on the Exchange. The Adviser cannot predict whether Shares will trade below, at or above their NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for the shares will be closely related to, but not identical to, the same forces influencing the prices of the Fund’s holdings trading individually or in the aggregate at any point in time. In addition, unlike conventional ETFs, the Fund is not an index fund. The Fund is actively managed and does not seek to replicate the performance of a specified index. Index based ETFs have generally traded at prices which closely correspond to NAV per share. Actively managed ETFs have a limited trading history and, therefore, there can be no assurance as to whether and/or the extent to which Shares will trade at premiums or discounts to NAV.

Index Call Option Risk. Because the exercise of index options is settled in cash, sellers of index call options, such as the Fund, cannot provide in advance for their potential settlement obligations by acquiring and holding the underlying securities. The Fund bears a risk that the value of the securities held by the Fund will vary from the value of the index and relative to the written index call option positions. Accordingly, the Fund may incur losses on the index call options that it has sold that exceed gains on other securities in its portfolio. The value of index options written by the Fund, which are priced daily, are affected by changes in the value of and dividend rates of the underlying common stocks in the index, changes in the actual or perceived volatility of the stock market and the remaining time to the options’ expiration. The value of the index options also may be adversely affected if the market for the index options becomes less liquid or smaller.

Management Risk. The portfolio managers’ judgments about the attractiveness, value and potential appreciation of particular stocks or other securities in which the Fund invests may prove to be incorrect and there is no guarantee that the portfolio managers’ judgment will produce the desired results.

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate-change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets.

Sector Risk. The Fund may have significant exposure to a limited number of issuers conducting business in the same sector or group of sectors. Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single sector or a group of sectors, and the securities of companies in that sector or group of sectors could react similarly to these or other developments. If the Fund invests more heavily in a particular sector, the value Shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, Share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of sectors. Additionally, some sectors could be subject to greater government regulation than other sectors. Therefore, changes in regulatory policies for those sectors may have a material effect on the value of securities issued by companies in those sectors.

Small and Medium Capitalization Securities Risk. The earnings and prospects of small and medium sized companies are more volatile than larger companies and may experience higher failure rates than larger companies. Small and medium sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures and may have limited markets, product lines, or financial resources and lack management experience.

Index returns assume reinvestment of dividends. Investors may not invest in the Index directly; unlike the Fund’s returns, the Index does not reflect any fees or expenses.

Investment Adviser: Main Management ETF Advisors, LLC (the “Adviser”)

Portfolio Managers: Kim D. Arthur, Chief Executive Officer of the Adviser, James W. Concidine, Chief Risk Officer of the Adviser, J. Richard Fredericks, Managing Director of the Adviser, and Alex Varner, Direct of Research of the Adviser, are primarily responsible for the day-to-day management of the Fund and have served the Fund as its portfolio managers since it commenced operations in 2021. Each portfolio manager is involved in rebalancing the Fund’s portfolio.

Purchase and Sale of Fund Shares: Individual Shares of the Fund may be purchased and sold in secondary market transactions through a broker dealer or at market price. Shares are listed for trading on the Exchange and trade at market prices rather than NAV. Shares may trade at a price that is greater than, at, or less than NAV. An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares on the secondary market (the “bid-ask spread”). Information on the Fund’s net asset value, market price, premiums and discounts and bid-ask spreads is available at www.mainmgtetfs.com.

Shares are listed for trading on the Exchange and trade at market prices rather than NAV. Shares may trade at a price that is greater than, at, or less than NAV.

Tax Information: Dividends and capital gain distributions you receive from the Fund, whether you reinvest your distributions in additional Fund shares or receive them in cash, are taxable to you at either ordinary income or capital gains tax rates unless you are investing through a tax-deferred plan such as an IRA or 401(k) plan. However, these dividend and capital gain distributions may be taxable upon their eventual withdrawal from tax-deferred plans.

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

FUND SUMMARY – Main International ETF 

Investment Objective: The Fund seeks to outperform the MSCI All Country World ex-USA Index® (the “Index”) over a full market cycle while maintaining below-benchmark risk.

Fees and Expenses of the Fund: This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Shares”). 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.

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 reflects the fee waiver and expense reimbursements for the duration of the waiver/reimbursement period only.

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. Although your actual costs may be higher or lower, based upon 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 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. The Fund has only recently commenced operations.

PRINCIPAL INVESTMENT STRATEGIES:

The Fund utilizes a “fund of funds” structure to invest in exchange traded funds (“ETFs”) that primarily provide exposure to non-U.S. equity securities of companies of any capitalization representing sectors and geographic regions that appear undervalued in comparison to their historical average price. The Adviser focuses its research on global macro-economic factors (relevant to the economy in general), micro-economic factors (relevant to individual companies) and fundamental factors (financial information that impacts the price or perceived value of a stock) to assess whether a sector or geographic region is expected to undergo a transformative change that could lead to near-term price appreciation of companies within that sector or region. Under normal circumstances, the Fund invests at least 50% of its total assets in funds that invest at least 50% of their respective total assets in securities of non-U.S. issuers organized or having their principal place of business outside the U.S.

The portfolio managers set price targets for each position and revisit a position when the price target is met, revising upwards when deemed appropriate or selling when the portfolio managers conclude the position no longer provides exposure to undervalued companies on the brink of a transformative change.

The Adviser rebalances the Fund’s portfolio when the portfolio managers deem appropriate. Given the longer-term nature of the Fund, an automatic monthly or quarterly rebalancing policy could be counterproductive to the Fund’s objective of seeking maximum return. From time to time, the Fund may use a covered call or covered put option strategy in an attempt to dampen volatility and generate additional returns.

The Fund is an actively managed ETF and does not seek to replicate the performance of a specified index. In selecting investments for the Fund’s portfolio, the Adviser adheres to the following investment process:

Assessing Market Conditions: The Adviser determines the Fund’s target allocations by identifying sectors (and their underlying industries and sub-industries) countries and regions it believes are poised for significant economic growth. To identify such sectors, countries and regions, the Adviser analyzes economic growth forecasts, changes in the factors driving growth, behavioral patterns among consumers, as well as other macroeconomic fundamentals over a 6- to 18-month horizon. The Adviser uses the Global Industry Classification Standard (“GICS”) in its sector analysis and may invest in country-specific sector funds. GICS sectors include: energy, materials, industrials, consumer discretionary, consumer staples, healthcare, financials, information technology, communication services, utilities and real estate.

Identifying the Appropriate ETFs: The Adviser then seeks to identify 5-20 index or actively managed ETFs to implement its strategic asset allocation by evaluating various factors in the respective ETFs including the respective underlying indexes they seek to track and portfolio holdings, sector exposure and weightings, liquidity profiles, and tracking error. At any given time, the Fund may have a significant percentage of its assets invested in one or more sectors or in one or more countries or geographic regions.

Option Strategy: The Fund pursues its objective by employing an option strategy of writing (selling) covered call or index based options on an amount from 0% to 100% of the value of the ETF shares in the Fund’s portfolio. The Fund seeks to earn income and gains both from dividends paid on the ETFs owned by the Fund and cash premiums received from writing or “selling”:

The Fund may not sell “naked” put or call options, i.e., equity options representing more shares of an ETF than the Fund has cash on hand and available to purchase or index options greater than the value of the underlying security.

Stock index options are put options and call options on various stock indices. The primary difference between stock options and index options occurs when index options are exercised. In the case of stock options, the underlying security, common stock, is delivered. However, upon the exercise of an index option, settlement does not occur by delivery of the securities comprising the index.

The option holder exercising the index option receives an amount of cash if the closing level of the stock index upon which the option is based is greater than, in the case of a call, or less than, in the case of a put, the exercise price of the option. This amount of cash is equal to the difference between the closing price of the stock index and the exercise price of the option expressed in dollars time a specified multiple.

A stock index fluctuates with changes in the market value of the stocks included in the index. A call option on a security is a contract that gives the holder of the option, in return for a premium, the right, but not the obligation, to buy from the writer of the option the security underlying the option at a specified exercise or “strike” price by or before the contract’s expiration. A put option on a security is a contract that gives the holder of the option, in return for a premium, the right to sell to the writer of the option the security underlying the option at a specified exercise or “strike” price. The writer of an option on a security has the obligation upon exercise of the option to purchase the underlying security at the exercise price. The Adviser’s option strategy typically targets one-month to three-month options. Options of any exercise price or maturity may be utilized.

Principal Investment Risks: As with all funds, there is the risk that you could lose money through your investment in the Fund. Many factors affect the Fund’s net asset value and price of shares and performance.

The following describes the risks the Fund bears directly or indirectly through investments in underlying ETFs. As with any ETF, there is no guarantee that the Fund will achieve its goal.

Allocation Risk: If the Fund’s strategy for allocating assets among different sectors and countries does not work as intended, the Fund may not achieve its objective or may underperform other funds with the same or similar investment strategy.

Authorized Participant Risk: Only an Authorized Participant that has entered into a contractual arrangement with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. The Fund’s distributor has entered into contracts with only a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem large blocks of shares known as “Creation Units,” Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs that invest in non-U.S. securities or other securities or instruments that have lower trading volumes.

Covered Call Risk: The writer of a covered call option forgoes any profit from increases in the market value of the underlying security covering the call option above the sum of the premium and the strike price of the call but retains the risk of loss if the underlying security declines in value. The Fund has no control over the exercise of the option by the option holder and may lose the benefit from any capital appreciation on the underlying security.

Currency Risk: Investments in foreign currencies are subject to political and economic risks, civil conflicts and war and greater volatility. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, imposition of currency controls and economic or political developments in the U.S. or abroad.

Derivatives Risk: The Fund’s use of options involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of an option may not correlate perfectly with the underlying asset, rate or index. Derivative prices may be highly volatile at times and may fluctuate substantially during a short period of time.

Emerging Markets Risk: Investing in emerging market nations involves not only the risks described below with respect to investing in foreign securities, but also other risks, including exposure to economic structures that are generally less diverse and mature, limited availability and reliability of information material to an investment decision, and exposure to political systems that can be expected to have less stability than those of developed countries. The typically small size of the markets of securities of issuers located in emerging markets and the possibility of a low or nonexistent volume of trading in those securities may also result in a lack of liquidity and in price volatility of those securities.

Exchange-Traded Fund Risk: The ETFs in which the Fund invests will not be able to replicate exactly the performance of the indices they track because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. This may result in a loss. Certain securities comprising the indices tracked by the ETFs may, from time to time, temporarily be unavailable, which may further impede the ETFs’ ability to track their applicable indices. ETFs in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the ETFs will be higher than the cost of investing directly in the ETFs underlying investments and may be higher than other mutual funds that invest directly in stocks and bonds. ETFs may also trade at a discount or premium to their net asset value.

ETF Structure Risk: The Fund is structured as an ETF and as a result is subject to the special risks, including:

o    The market price for the Shares may deviate from an ETF’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Shares than an ETF’s NAV, which is reflected in the bid and ask price for Shares or in the closing price.

Equity Risk: Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The equity securities held by the Fund may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors affecting securities markets generally, the equity securities of a particular sector, or a particular company.

Fluctuation of Net Asset Value Risk: The NAV of the Shares will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of the Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for the shares on the Exchange. The Adviser cannot predict whether the Shares will trade below, at or above their NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for the shares will be closely related to, but not identical to, the same forces influencing the prices of the Fund’s holdings trading individually or in the aggregate at any point in time. In addition, unlike conventional ETFs, the Fund is not an index fund. The Fund is actively managed and does not seek to replicate the performance of a specified index. Index based ETFs have generally traded at prices which closely correspond to NAV per share. Actively managed ETFs have a limited trading history and, therefore, there can be no assurance as to whether and/or the extent to which the Shares will trade at premiums or discounts to NAV.

Foreign Securities Risk. Foreign companies are generally not subject to the same regulatory requirements of U.S. companies thereby resulting in less publicly available information about these companies. In addition, foreign accounting, auditing and financial reporting standards generally differ from those applicable to U.S. companies.

Index Call Option Risk: Because the exercise of index options is settled in cash, sellers of index call options, such as the Fund, cannot provide in advance for their potential settlement obligations by acquiring and holding the underlying securities. The Fund bears a risk that the value of the securities held by the Fund will vary from the value of the index and relative to the written index call option positions. Accordingly, the Fund may incur losses on the index call options that it has sold that exceed gains on other securities in its portfolio. The value of index options written by the Fund, which will be priced daily, will be affected by changes in the value of and dividend rates of the underlying common stocks in the index, changes in the actual or perceived volatility of the stock market and the remaining time to the options’ expiration. The value of the index options also may be adversely affected if the market for the index options becomes less liquid or smaller.

Large Capitalization Company 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.

Limited History of Operations Risk: The Fund is a new exchange traded fund and has a limited history of operations for investors to evaluate.

Management Risk: The portfolio managers’ judgments about the attractiveness, value and potential appreciation of particular stocks or other securities in which the Fund invests may prove to be incorrect and there is no guarantee that the portfolio manager’s judgment will produce the desired results.

Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation
(or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate-change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets.

Sector Risk: The Fund may have significant exposure to a limited number of issuers conducting business in the same sector or group of sectors. Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single sector or a group of sectors, and the securities of companies in that sector or group of sectors could react similarly to these or other developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of sectors. Additionally, some sectors could be subject to greater government regulation than other sectors. Therefore, changes in regulatory policies for those sectors may have a material effect on the value of securities issued by companies in those sectors.

Performance: Because the Fund has only recently commenced investment operations, no performance information is presented for the Fund at this time. In the future, performance information will be presented in this section of this prospectus. Also, shareholder reports containing financial and performance information will be mailed to shareholders semi-annually. Updated performance information will be available at no cost by visiting www.mainmgtetfs.com or by calling 1-866-ETF-XPRT 1(866) 383-9778.

Investment Adviser: Main Management ETF Advisors, LLC (the “Adviser”)

Portfolio Managers: Kim D. Arthur, Chief Executive Officer of the Adviser, James W. Concidine, Chief Risk Officer of the Adviser, J. Richard Fredericks, Managing Director of the Adviser, and Alex Varner, Director of Research of the Adviser, are primarily responsible for the day-to-day management of the Fund and have served the Fund as its portfolio managers since it commenced operations in 2022. Each portfolio manager is involved in rebalancing the Fund’s portfolio.

Purchase and Sale of Fund Shares: Individual Shares may be purchased and sold in secondary market transactions through a broker dealer or at market price. Shares are listed for trading on the Exchange and trade at market prices rather than NAV. Shares may trade at a price that is greater than, at, or less than NAV. An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the second market (the “bid-ask spread”). Because the Fund has only recently commenced investment operations, no information on the Fund’s net asset value, market price, premiums and discounts and bid-asks spreads is presented at this time. In the future, this information will be presented in this section of the Prospectus and on the Fund’s website at www.mainmgtetfs.com.

Tax Information: Dividends and capital gain distributions you receive from the Fund, whether you reinvest your distributions in additional Fund shares or receive them in cash, are taxable to you at either ordinary income or capital gains tax rates unless you are investing through a tax-deferred plan such as an IRA or 401(k) plan. However, these dividend and capital gain distributions may be taxable upon their eventual withdrawal from tax-deferred plans.

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

ADDITIONAL INFORMATION ABOUT PRINCIPAL INVESTMENT STRATEGIES AND RELATED RISKS 

INVESTMENT OBJECTIVE: The investment objective of each of Main Sector Rotation ETF (“Sector Rotation”), Main Thematic Innovation ETF (“Thematic Innovation”), and Main International ETF (“International”)(each a “Fund” and collectively, the “Funds”) is listed below:

Each Fund’s investment objective may be changed without shareholder approval upon 60 days’ written notice to shareholders. Each Fund’s investment policies may be changed by the Trust’s Board of Trustees without shareholder approval unless otherwise noted in this prospectus or the Statement of Additional Information.

PRINCIPAL INVESTMENT STRATEGIES:

Sector Rotation

The Fund utilizes a “fund of funds” structure to invest in sector-based exchange traded funds (“ETFs”). The Fund seeks to achieve its objective through dynamic sector rotation. The Fund’s adviser, Main Management ETF Advisors, LLC
(the “Adviser”) focuses its research primarily on sector selection by carefully reviewing the sectors, industries, and sub-industries in the Fund’s portfolio.

The Adviser chooses sectors it believes are undervalued and poised to respond favorably to financial market catalysts. The Adviser believes this approach can produce a high potential for share price growth. The Fund’s strategy uses systematic, fundamental analysis to evaluate and rank sectors and uncover potential catalysts. The Fund will sell a security when it achieves its target price and is, in the opinion of the Adviser, no longer undervalued. The Fund may overweight or underweight a sector or sectors relative to the Fund’s benchmark based on valuation. The Fund may invest in securities of any market capitalization or country and denominated in any currency.

The Fund is an actively managed ETF and does not seek to replicate the performance of a specified index. In selecting investments for the Fund’s portfolio, the Adviser adheres to the following investment process.

The Adviser believes that, over time, sector selection is more important than individual security selection in limiting the variability inherent in equity security investing. The Adviser seeks to gain an understanding of the economic landscape and to identify catalysts which may allow for near term sector appreciation by analyzing interest and currency rates, inflation trends, economic growth forecasts and other capital market fundamentals of the market sectors, sub-sectors, and industries.

Assessing Market Conditions. The Adviser determines the Fund’s target allocations by analyzing market sectors and their underlying industries and sub-industries. The Adviser uses the Global Industry Classification Standard (“GICS”) in its sector analysis. GICS sectors include: energy, materials, industrials, consumer discretionary, consumer staples, healthcare, financials, information technology, communication services, utilities, and real estate. The Adviser analyzes economic growth forecasts, inflation trends, and other macroeconomic and capital market fundamentals. The Adviser identifies opportunities for near-term growth in value that are facilitated by events or changes within sectors that its research has identified as “undervalued” within the U.S. equity market.

Identifying the Appropriate ETFs. The Fund invests in equity ETFs. The Adviser seeks to identify the most appropriate U.S. Sector ETFs to implement its strategic asset allocation and sector views by evaluating such factors as the respective ETF’s:

Thematic Innovation

The Fund utilizes a “fund of funds” structure to invest in theme-based equity ETFs. The Fund seeks to achieve its objective through dynamic thematic rotation. The Adviser focuses its research primarily on identifying emerging, disruptive, and innovative themes that have a large market demand or “addressable market.” The Adviser rotates among themes with large addressable markets which may range from nascent technologies to those on the cusp of widespread adoption and buys securities of ETFs investing in those themes.

As seen from past disruptive technologies, the market often does not initially price a theme appropriately, or even for several years, as the market’s response to the theme is often underestimated. Disruptors must continually reinvest in their future and expand their reach as they grow and these moves are hard for markets to accurately price, resulting in the potential for appreciation.

The portfolio managers set price targets for each position and revisits a position when the price target is met, revising upwards when deemed appropriate or selling when the investment committee concludes the theme has either run its course or is no longer likely to provide further exposure to growth, disruption, or innovation. The investment committee is composed of three of the four portfolio managers. Looking for themes with large market demand may mean price targets are revised upwards multiple times. The holding period is long-term as it may take years or even decades for themes to realize their full potential.

The Adviser believes that, over time, thematic selection is more important than individual security selection in limiting the variability inherent in equity security investing. The Adviser seeks to gain an understanding of the economic landscape and to identify catalysts which may allow for near term sector appreciation by analyzing interest and currency rates, inflation trends, economic growth forecasts and other capital market fundamentals of the market sectors and their industries and sub-industries.

The Adviser rebalances the Fund’s portfolio when the investment committee deems appropriate. Given the longer-term nature of thematic development, an automatic monthly or quarterly rebalancing policy could be counterproductive to the Fund’s objective of seeking maximum return. From time to time, the Fund may use a covered call or covered put option strategy in an attempt to dampen volatility and generate additional returns.

The Fund is an actively managed ETF and does not seek to replicate the performance of a specified index. In selecting investments for the Fund’s portfolio, the Adviser adheres to the investment process described below. The Fund may seek investment exposure to bitcoin by investing in the Grayscale Bitcoin Trust. Under normal circumstances, no more than 10% of the Fund’s assets may be invested in Grayscale Bitcoin Trust. The Fund will not make additional investments in the Grayscale Bitcoin Trust if, as a result of the investment, the amount of shares of the Grayscale Bitcoin Trust would be more than 5% of the Fund’s assets at the time of the investment.

Assessing Market Conditions. The Adviser determines the Fund’s target allocations by analyzing developing and ongoing technological and behavioral themes and their underlying addressable markets. The Adviser identifies themes consisting of securities in the aggregate that are poised for significant growth, disruption, or innovation. To identify such themes, the Adviser analyzes economic growth forecasts, changes in the factors driving growth, behavioral patterns among consumers, as well as other macroeconomic fundamentals. Themes may include: genomics, fintech, e-commerce, robotics, artificial intelligence, cyber security, clean energy, cloud computing, autonomous tech, gaming & e-sports, and pet care. The Adviser identifies themes that have large addressable markets and may be still early in their life cycle. In addition, the advisor considers fundamental factors such as Price to Growth, Price to Earnings, Price to Book, and Price to Sales. The growth rate and size of the addressable market are the primary metrics of consideration.

Identifying the Appropriate ETFs: The Fund invests in equity ETFs. The Adviser seeks to identify 5-15 theme-based ETFs to implement its strategic asset allocation and sector views by evaluating such factors as the respective ETF’s:

At any given time, the Fund may have a significantly higher percentage of its assets invested in one or more sectors in comparison to other sectors.

International

The Fund utilizes a “fund of funds” structure to invest in exchange traded funds (“ETFs”) that primarily provide exposure to non-U.S. equity securities of companies of any capitalization representing sectors and geographic regions that appear undervalued in comparison to their historical average price. The Adviser focuses its research on global macro-economic factors relevant to the economy in general such as economic outputs, unemployment and inflation; micro-economic factors relevant to individual companies such as the availability of employees, distribution channels and consumer base; and fundamental factors such as average price to growth ratio, price to earnings ratio, price to book ratio (i.e., the ratio of current market value compared to balance sheet value), price to sales ratio, supply and demand dynamics, cash flows and debt ratios of companies within a particular sector or geographic region. The Adviser analyzes such data to assess whether a sector, country or geographic region is expected to undergo a transformative change that could lead to near-term price appreciation of companies within that sector or region. Under normal circumstances, the Fund invests at least 50% of its total assets in funds that invest at least 50% of their respective total assets in securities of non-U.S. issuers organized or having their principal place of business outside the U.S.

The portfolio managers set price targets for each position and revisit a position when the price target is met, revising upwards when deemed appropriate or selling when the portfolio managers conclude the position no longer provides exposure to undervalued companies on the brink of a transformative change. The holding period is long-term as it may take years or even decades for certain companies to realize their full potential.

The Adviser rebalances the Fund’s portfolio when the portfolio managers deem appropriate. Given the longer-term nature of the Fund, an automatic monthly or quarterly rebalancing policy could be counterproductive to the Fund’s objective of seeking maximum return. From time to time, the Fund may use a covered call or covered put option strategy in an attempt to dampen volatility and generate additional returns.

The Fund is an actively managed ETF and does not seek to replicate the performance of a specified index. In selecting investments for the Fund’s portfolio, the Adviser adheres to the following investment process:

Assessing Market Conditions: The Adviser determines the Fund’s target allocations by identifying sectors (and their underlying industries and sub-industries) countries and regions it believes are poised for significant economic growth. To identify such sectors, countries and regions, the Adviser analyzes economic growth forecasts, changes in the factors driving growth, behavioral patterns among consumers, as well as other macroeconomic fundamentals over a 6 to 18-month horizon. The Adviser uses the Global Industry Classification Standard (“GICS”) in its sector analysis and may invest in country-specific sector funds. GICS sectors include: energy, materials, industrials, consumer discretionary, consumer staples, healthcare, financials, information technology, communication services, utilities and real estate.

Identifying the Appropriate ETFs: The Fund invests in equity ETFs. The Adviser seeks to identify 5-20 index or actively managed ETFs to implement its strategic asset allocation and sector views by evaluating such factors as the respective ETF’s:

At any given time, the Fund may have a significant percentage of its assets invested in one or more sectors than other sectors.

The Funds

Option Strategy. Each Fund may from time to time incorporate a covered call option writing strategy. Covered call option writing is an investment strategy of writing (selling) call options against securities owned by the Fund to generate additional returns from the option premium. Each Fund may also seek returns by writing (selling) secured put options. A “put option” is an option contract that gives the owner the right to sell the underlying security at a specified price (the strike price) until its expiration at a fixed date in the future. Each Fund seeks to achieve risk-adjusted returns through targeted allocations by analyzing interest and currency rates, inflation trends, economic growth forecasts, and other global and capital market fundamentals. Each Fund’s option strategy may also have the benefit of reducing the volatility of the Fund’s portfolio in comparison to that of broad equity market indexes.

Each Fund pursues its options strategy by writing (selling) covered call or index-based options on an amount from 0% to 100% of the value of the ETF shares in the Fund’s portfolio. Each Fund seeks to earn income and gains both from dividends paid on the ETFs owned by the Fund and cash premiums received from writing or “selling”:

Each Fund may not sell “naked” put or call options, i.e., equity options representing more shares of an ETF than the Fund has cash on hand and available to purchase or index options greater than the value of the underlying security. Stock index options are put options and call options on various stock indices. The primary difference between stock options and index options occurs when index options are exercised. In the case of stock options, the underlying security, common stock, is delivered. However, upon the exercise of an index option, settlement does not occur by delivery of the securities comprising the index. The option holder exercising the index option receives an amount of cash if the closing level of the stock index upon which the option is based is greater than, in the case of a call, or less than, in the case of a put, the exercise price of the option. This amount of cash is equal to the difference between the closing price of the stock index and the exercise price of the option expressed in dollars times a specified multiple. A stock index fluctuates with changes in the market value of the stocks included in the index. A call option on a security is a contract that gives the holder of the option, in return for a premium, the right, but not the obligation, to buy from the writer of the option the security underlying the option at a specified exercise or “strike” price by or before the contract’s expiration. A put option on a security is a contract that gives the holder of the option, in return for a premium, the right to sell to the writer of the option the security underlying the option at a specified exercise or “strike” price. The writer of an option on a security has the obligation upon exercise of the option to purchase the underlying security at the exercise price.

TEMPORARY INVESTMENTS: To respond to adverse market, economic, political or other conditions, each Fund may invest 100% of its total assets, without limitation, in high-quality short-term debt securities and money market instruments. These short-term debt securities and money market instruments include: shares of money market mutual funds, commercial paper, certificates of deposit, bankers’ acceptances, U.S. government securities and repurchase agreements. While a Fund is in a defensive position, the Fund may not achieve its investment objective. Furthermore, to the extent that a Fund invests in money market mutual funds for cash positions, there will be some duplication of expenses because the Fund pays its pro-rata portion of such money market funds’ advisory fees and operational fees. Each Fund may also invest a substantial portion of its assets in such instruments at any time to maintain liquidity or pending selection of investments in accordance with its policies.

PRINCIPAL INVESTMENT RISKS 

The following describes the risks each Fund bears directly or indirectly through investments in underlying ETFs. As with any ETF, there is no guarantee that a Fund will achieve its goal.

Allocation Risk. The risk that if the Fund’s strategy for allocating assets among different assets classes does not work as intended, the Fund may not achieve its objective or may underperform other funds with the same or similar investment strategy.

Authorized Participant Risk. Only an Authorized Participant that has entered into a contractual arrangement with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. The Fund’s distributor has entered into contracts only with a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs that invest in non-U.S. securities or other securities or instruments that have lower trading volumes.

Covered Call Risk. The writer of a covered call option forgoes any profit from increases in the market value of the underlying security covering the call option above the sum of the premium and the strike price of the call but retains the risk of loss if the underlying security declines in value. The Fund will have no control over the exercise of the option by the option holder and may lose the benefit from any capital appreciation on the underlying security. A number of factors may influence the option holder’s decision to exercise the option, including the value of the underlying security, price volatility, dividend yield and interest rates. To the extent that these factors increase the value of the call option, the option holder is more likely to exercise the option, which may negatively affect the Fund.

Currency Risk. Investments in foreign currencies are subject to political and economic risks, civil conflicts and war and greater volatility. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, imposition of currency controls and economic or political developments in the U.S. or abroad. Changes in foreign economies and political climates are more likely to affect the Fund than a mutual fund that invests exclusively in dollar denominated securities of U.S. issuers.

Derivatives Risk. The Fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or

index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities including:

Emerging Markets Risk: (International only) Investing in emerging market nations involves not only the risks described below with respect to investing in foreign securities, but also other risks, including exposure to economic structures that are generally less diverse and mature, limited availability and reliability of information material to an investment decision, and exposure to political systems that can be expected to have less stability than those of developed countries. The typically small size of the markets of securities of issuers located in emerging markets and the possibility of a low or nonexistent volume of trading in those securities may also result in a lack of liquidity and in price volatility of those securities.

Exchange-Traded Fund Risk. ETFs are investment companies, which may be managed or unmanaged, that generally seek to track the performance of a specific index. The value of ETFs can be expected to increase and decrease in value in proportion to increases and decreases in the indices that they are designed to track. The volatility of different index tracking stocks can be expected to vary in proportion to the volatility of the particular index they track. The ETFs in which the Fund invests may not be able to replicate exactly the performance of the indices they track because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. This may result in a loss. ETFs are traded similarly to stocks of individual companies. Although an ETF is designed to provide investment performance corresponding to its index, it may not be able to exactly replicate the performance of its index because of its operating expenses and other factors. ETFs may also trade at a discount or premium to their net asset value. In addition, ETFs have certain inherent risks generally associated with investments in a portfolio of securities, in which the ETF is invested, including the risk that the general level of stock prices may decline, thereby adversely affecting the value of each unit of the ETF. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained. The Fund’s investments in certain commodities-linked ETFs may be limited by tax considerations, including the Fund’s intention to qualify annually as a regulated investment company under the Internal Revenue Code of 1986, as amended. ETFs in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in an ETF and may be higher than other mutual funds that invest directly in stocks and bonds.

ETF Structure Risk. The Fund is structured as an ETF and as a result is subject to the special risks, including:

Equity Risk. Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The equity securities held by the Fund may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors affecting securities markets generally, the equity securities of a particular sector, or a particular company.

Fluctuation of Net Asset Value Risk. The NAV of Shares generally fluctuates with changes in the market value of the Fund’s holdings. The market prices of the Shares generally fluctuates in accordance with changes in NAV as well as the relative supply of and demand for the shares on the Exchange. The Adviser cannot predict whether Shares will trade below, at or above their NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for the shares will be closely related to, but not identical to, the same forces influencing the prices of the Fund’s holdings trading individually or in the aggregate at any point in time. In addition, unlike conventional ETFs, the Fund is not an index fund. The Fund is actively managed and does not seek to replicate the performance of a specified index. Index based ETFs have generally traded at prices which closely correspond to NAV per share. Actively managed ETFs have a limited trading history and, therefore, there can be no assurance as to whether and/or the extent to which Shares will trade at premiums or discounts to NAV.

Foreign Securities Risk (Sector Rotation and International only). The Fund could be subject to greater risks because the Fund’s performance may depend on issues other than the performance of a particular company or U.S. market sector. Changes in foreign economies and political climates are more likely to affect the Fund than a mutual fund that invests exclusively in U.S. companies. The value of foreign securities is also affected by the value of the local currency relative to the U.S. dollar. There may also be less government supervision of foreign markets, resulting in non-uniform accounting practices and less publicly available information. The values of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax), changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. In addition, foreign brokerage commissions, custody fees and other costs of investing in foreign securities are

generally higher than in the United States. Investments in foreign issues could be affected by other factors not present in the United States, including expropriation, armed conflict, confiscatory taxation, and potential difficulties in enforcing contractual obligations. As a result, the Fund may be exposed to greater risk and will be more dependent on the Adviser’s ability to assess such risk than if the Fund invested solely in more developed countries.

Index Call Option Risk. Because the exercise of index options is settled in cash, sellers of index call options, such as the Fund, cannot provide in advance for their potential settlement obligations by acquiring and holding the underlying securities. The Fund bears a risk that the value of the securities held by the Fund will vary from the value of the index and relative to the written index call option positions. Accordingly, the Fund may incur losses on the index call options that it has sold that exceed gains on other securities in its portfolio. The value of index options written by the Fund, which are priced daily, are affected by changes in the value of and dividend rates of the underlying common stocks in the index, changes in the actual or perceived volatility of the stock market and the remaining time to the options’ expiration. The value of the index options also may be adversely affected if the market for the index options becomes less liquid or smaller.

As the writer of an index call option, the Fund foregoes, during the option’s life, the opportunity to profit from increases in the market value of the index underlying the call option above the sum of the premium and the strike price of the option, but will retain the risk of loss should the market value of the index underlying the call option decline. The purchaser of the index call option has the right to any appreciation in the value of the underlying index over the exercise price upon the exercise of the call option or the expiration date.

Large Capitalization Securities Risk (Sector Rotation and International only). The value of investments in larger companies may not rise as much as smaller companies, or larger companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.

Limited History of Operations Risk (International only): The Fund is a new exchange traded fund and has a limited history of operations for investors to evaluate.

Management Risk. The Adviser’s reliance on its strategy and its judgments about the value and potential appreciation securities in which the Fund invests may prove to be incorrect, including the Adviser’s tactical allocation of the Fund’s portfolio among its investments. The ability of the Fund to meet its investment objective is directly related to the Adviser’s proprietary investment process. The Adviser’s assessment of the relative value of securities, their 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.

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate-change and climate-related events, pandemics, epidemics, terrorism, international conflicts regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund’s portfolio. The COVID-19 global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, as well as the forced or voluntary closure of, or operational changes to, many retail and other businesses, had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. Therefore, the Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates can have the same impact on all types of securities and instruments. In times of severe market disruptions you could lose your entire investment.

Sector Risk. The Fund will be subject to the risk that economic, political or other conditions that have a negative effect on these sectors may adversely affect the Fund to a greater extent than if the Fund’s assets were invested in a wider variety of sectors or industries. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of sectors. Additionally, some sectors could be subject to greater government regulation than other sectors. Therefore, changes in regulatory policies for those sectors may have a material effect on the value of securities issued by companies in those sectors. To the extent that the Fund’s investments are significantly exposed to a particular sector, the Fund will be susceptible to loss due to adverse occurrences affecting that sector.

Small and Medium Capitalization Securities Risk (Sector and Thematic Innovation only). The stocks of small and medium capitalization companies involve substantial risk. These companies may have limited product lines, markets or financial resources, and they may be dependent on a limited management group. Securities of these companies may be subject to more abrupt or erratic market movements than those of larger, more established companies or the market averages in general.

PORTFOLIO HOLDINGS DISCLOSURE: A description of the Funds’ policies regarding the release of portfolio holdings information is available in the Funds’ Statement of Additional Information (“SAI”) and on the Adviser’s website, www.mainmgtetfs.com.

OPERATIONAL AND CYBERSECURITY RISK: Fund operations, including business, financial, accounting, data processing systems or other operating systems and facilities may be disrupted, disabled or damaged as a result of a number of factors, including events that are wholly or partially beyond our control. For example, there could be electrical or telecommunications outages; degradation or loss of internet or web services; natural disasters, such as earthquakes, tornados and hurricanes; climate-change and climate-related events; disease pandemics; or events arising from local or larger scale political or social events, as well as terrorist acts.

The Funds are also subject to the risk of potential cyber incidents, which may include, but are not limited to, the harming of or unauthorized access to digital systems (for example, through “hacking” or infection by computer viruses or other malicious software code), denial-of-service attacks on websites, and the inadvertent or intentional release of confidential or proprietary information. Cyber incidents may, among other things, harm Fund operations, result in financial losses to a Fund and its shareholders, cause the release of confidential or highly restricted information, and result in regulatory penalties, reputational damage, and/or increased compliance, reimbursement or other compensation costs. Fund operations that may be disrupted or halted due to a cyber incident include trading, the processing of shareholder transactions, and the calculation of a Fund’s NAV.

Issues affecting operating systems and facilities through cyber incidents, any of the scenarios described above, or other factors, may harm the Funds by affecting the Adviser, or other service providers, or issuers of securities in which a Fund invests. Although the Funds have business continuity plans and other safeguards in place, including what the Funds believe to be robust information security procedures and controls, there is no guarantee that these measures will prevent cyber incidents or prevent or ameliorate the effects of significant and widespread disruption to our physical infrastructure or operating systems. Furthermore, the Funds cannot directly control the security or other measures taken by unaffiliated service providers or the issuers of securities in which the Funds invest. Such risks at issuers of securities in which the Funds invest could result in material adverse consequences for such issuers and may cause a Fund’s investment in such securities to lose value.

SECURITIES LENDING: To generate additional income, each Fund may lend its portfolio securities to qualified banks, broker-dealers and other financial institutions (referred to as “borrowers”), provided that: (i) the loan is continuously secured by collateral in cash, cash equivalents, bank letters of credit or U.S. government securities equal to at least 100% of the value of the loaned securities, and such collateral is valued, or “marked to market,” daily (borrowers are required to furnish additional collateral to the Fund as necessary to fully cover its obligations); (ii) the loan may be recalled at any time by the Fund and the loaned securities returned; (iii) the Fund will receive any interest, dividends or other distributions paid on the loaned securities; and (iv) the aggregate value of the loaned securities will not exceed 33 1/3% of the Fund’s total assets. A Fund generally retains part or all of the interest received on investment of the cash collateral or receives a fee from the borrower. While this practice will not impact a Fund’s principal investment strategy, it does subject the Fund to the securities lending risk described in this Prospectus.

Loans of securities involve a risk that the borrower may fail to return the securities or may fail to maintain the proper amount of collateral, which may result in a loss of money by a Fund or a delay in recovering the loaned securities. In addition, in the event of bankruptcy of the borrower, a Fund could experience delays in recovering the loaned securities or only recover cash or a security of equivalent value. Therefore, each Fund only enters into portfolio loans after a review of all pertinent factors by the Adviser under the oversight of the Board of Trustees, including the creditworthiness of the borrower and then only if the consideration to be received from such loans would justify the risk. Creditworthiness will be monitored on an ongoing basis by the Adviser. An attempt may be made to recall a loan in time to vote proxies if fund management has knowledge of a material vote with respect to the loaned securities and the matter involved would have a material effect on a Fund’s investment in the security. The costs of securities lending are not reflected in each Fund’s “Annual Fund Operating Expenses” table or “Example” above.

Securities Lending Risk. Each Fund may lend its portfolio securities to financial institutions under guidelines adopted by the Board, including a requirement that the Fund receive cash collateral from the borrower equal to no less than 100% of the market value of the securities loaned. Each Fund may invest this cash collateral in high quality short-term debt obligations, government obligations, bank guarantees or money market mutual funds. Securities lending involves two primary risks: “investment risk” and “borrower default risk.” Investment risk is the risk that a Fund will lose money from the investment of the cash collateral. Borrower default risk is the risk that a Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

MANAGEMENT 

Investment Adviser:

Main Management ETF Advisers, LLC, located at 601 California Street, Suite 200, San Francisco, California 94108, serves as the Funds’ investment adviser (the “Adviser”0. The Adviser is registered with the SEC as an investment adviser under the Investment Advisers Act of 1940, as amended. The Adviser is a Delaware limited liability corporation formed in 2017. The Adviser manages ETFs and, as of October, 30, 2022, has approximately $1.01 billion in assets under management.

Subject to the supervision of the Board of Trustees, the Adviser is responsible for managing each Fund’s investments, placing trade orders and providing related administrative services and facilities under an advisory agreement between the Funds and the Adviser (the “Investment Advisory Agreement”).

The management fee set forth in the Investment Advisory Agreement for Sector Rotation is 0.50% of its average net assets; the management fee for Thematic Innovation is 0.65% of its average net assets; and the management for International is 0.55% annually, each to be paid on a monthly basis. In addition to investment advisory fees, each Fund pays other expenses including costs incurred in connection with the maintenance of securities law registration, printing and mailing prospectuses and statements of additional information to shareholders, certain financial accounting services, taxes or governmental fees, custodial, transfer and shareholder servicing agent costs, expenses of outside counsel and independent accountants, preparation of shareholder reports and expenses of trustee and shareholder meetings. A discussion regarding the basis for the Board’s most recent renewal of the Investment Advisory Agreement with respect to Sector Rotation and Thematic Innovation is available in Funds’ annual report to shareholders dated October 31, 2022. A discussion regarding the basis of the Board’s approval of the Investment Advisory Agreement with respect to International will be available in Funds’ next semi-annual report to shareholders.

The Adviser has contractually agreed to reduce its fees and/or absorb expenses of Sector Rotation and Thematic Innovation, until at least February 28, 2031; and contractually agreed to reduce its fees and/or absorb expenses of International until at least February 28, 2024, to ensure that total annual fund operating expenses after fee waiver and/or reimbursement excluding (i) any front-end or contingent deferred loads; (ii) brokerage fees and commissions; (iii) acquired fund fees and expenses; (iv) fees and expenses associated with investments in other collective investment vehicles or derivative instruments (including for example option and swap fees and expenses); (v) borrowing costs (such as interest and dividend expense on securities sold short); (vi) taxes; and (vii) extraordinary expenses, such as litigation expenses (which may include indemnification of Fund officers and Trustees, contractual indemnification of Fund service providers (other than the Adviser)) will not exceed 0.65% of the average daily net assets for Sector Rotation, 0.99% of the average daily net assets for Thematic Innovation, and 0.64% of the average daily net assets for International; subject to possible recoupment from the relevant Fund in future years on a rolling three-year basis (within the three years after the fees have been waived or reimbursed) if such recoupment can be achieved within the lesser of the expense limitations or those in place at the time of waiver and the expense limitation in place at the time of recapture. The expense limit arrangement may not be terminated during this time period without prior approval of the Board of Trustees on 60 days’ written notice to the Adviser. Fee waiver and reimbursement arrangements can decrease a Fund’s expenses and boost its performance.

HOW SHARES ARE PRICED 

Shares of each Fund are bought and sold at a price in two different ways depending upon the type of investor.

All investors including retail investors and Authorized Participants may buy and sell Shares in secondary market transactions through brokers at market prices and the Shares will trade at market prices.

Only Authorized Participants may buy and redeem Shares from a Fund directly and those transactions are effected at the Fund’s NAV.

The NAV of each Fund is determined at the close of regular trading (normally 4:00 p.m. Eastern Time) on each day the Exchange is open for business. NAV is computed by determining, the aggregate market value of all assets of a Fund, less its liabilities, divided by the total number of Shares outstanding ((assets-liabilities)/number of Shares = NAV). The Exchange is closed on weekends and New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day and Christmas Day (“Exchange Close”). The NAV takes into account, the expenses and fees of a Fund, including management, administration, and distribution fees, which are accrued daily. The determination of NAV for a Fund for a particular day is applicable to all applications for the purchase of Shares, as well as all requests for the redemption of shares, received by the Fund (or an authorized broker or agent, or its authorized designee) before the close of trading on the Exchange on that day.

Generally, each Fund’s portfolio securities, including securities issued by ETFs, are valued each day at the last quoted sales price on each security’s primary exchange. Securities traded or dealt in upon one or more securities exchanges (whether domestic or foreign) for which market quotations are readily available and not subject to restrictions against resale shall be valued at the last quoted sales price on the primary exchange or, in the absence of a sale on the primary exchange, at the mean between the current bid and ask prices on such exchange. Securities primarily traded in the National Association of Securities Dealers’ Automated Quotation System (“NASDAQ”) National Market System for which market quotations are readily available shall be valued using the NASDAQ Official Closing Price. Securities that are not traded or dealt in any securities exchange (whether domestic or foreign) and for which over-the-counter market quotations are readily available generally shall be valued at the last sale price or, in the absence of a sale, at the mean between the current bid and ask price on such over-the-counter market. Debt securities not traded on an exchange may be valued at prices supplied by a pricing agent(s) based on broker or dealer supplied valuations or matrix pricing, a method of valuing securities by reference to the value of other securities with similar characteristics, such as rating, interest rate and maturity.

If market quotations are not readily available, securities are valued at their fair market value as determined using the
“fair value” procedures approved by the Board. Fair value pricing involves subjective judgement and it is possible that the fair value determined for a security may be materially different than the value that could be realized upon the sale of that security. The fair value prices can differ from market prices when they become available or when a price becomes available. The Board of Trustees has designated the Adviser as its Valuation Designee for the execution of these procedures. The Valuation Designee may also enlist third party consultants such as an audit firm or financial officer of a security issuer on an as-needed basis to assist in determining a security-specific fair value. The Board of Trustees reviews the execution of this process and the resultant fair value prices at least quarterly to assure the process produces reliable results.

Each Fund may use independent pricing services to assist in calculating the value of its portfolio securities.
In addition, market prices for foreign securities are not determined at the same time of day as the NAV for the Funds. Because each Fund may invest in underlying ETFs which hold portfolio securities primarily listed on foreign exchanges, and these exchanges may trade on weekends or other days when the underlying ETFs do not price their shares, the value of some of the Fund’s portfolio securities may change on days when you may not be able to buy or sell Fund shares.

HOW TO BUY AND SELL SHARES 

Shares of Sector Rotation are listed for trading on the Exchange under the symbol SECT; shares of Thematic Innovation are listed for trading on the Exchange under the symbol TMAT; and shares of International are listed for trading on the Exchange under the symbol INTL. Share prices are reported in dollars and cents per Share. Shares can be bought and sold on the secondary market throughout the trading day like other publicly traded shares and Shares typically trade in blocks of less than a Creation Unit. There is no minimum investment required. Shares may only be purchased and sold on the secondary market when the Exchange is open for trading. The Exchange is open for trading Monday through Friday and is closed on weekends and the following holidays, as observed: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Share prices are reported in dollars and cents per Share. There is no minimum investment required. When buying or selling Shares through a broker, you will incur customary brokerage commissions and charges, and you may pay some or all of the spread between the bid and the offered price in the secondary market on each leg of a round trip (purchase and sale) transaction.

A creation transaction, which is subject to acceptance by the Distributor and the relevant Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities, assets or other positions (a “creation basket”), and an amount of cash (including any cash representing the value of substituted securities, assets or other positions), if any, which together approximate the holdings of the Fund in exchange for a specified number of Creation Units. Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities, assets or other positions (a “redemption basket”) held by the Fund and an amount of cash (including any portion of such securities for which cash may be substituted). A Fund may substitute cash for any Fund Security and Creation Units may be redeemed for a substantial portion of cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund. Creation and redemption baskets may differ and the Fund will accept “custom baskets.” Authorized Participants may create or redeem Creation Units for their own accounts or for customers, including, without limitation, affiliates of the Fund.

The prices at which creations and redemptions occur are based on the next calculation of NAV after a creation or redemption order is received in an acceptable form under the authorized participant agreement.

In the event of a system failure or other interruption, including disruptions at market makers or Authorized Participants, orders to purchase or redeem Creation Units either may not be executed according to a Fund’s instructions or may not be executed at all, or the Fund may not be able to place or change orders.

To the extent a Fund engages in in-kind transactions, the Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined in Rule 144A under the 1933 Act, will not be able to receive restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant that has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Funds’ SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of ta Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(a)(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Each Fund may liquidate and terminate at any time without shareholder approval.

Premium/Discount Information

Investors other than Authorized Participants will buy and sell Shares in secondary market transactions through brokers at market prices and the Shares will trade at market prices. The market price of Shares may be greater than, equal to, or less than NAV. Market forces of supply and demand, economic conditions and other factors may affect the trading prices of Shares.

Book Entry

Shares are held in book entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding Shares and is recognized as the owner of all Shares for all purposes.

Investors owning Shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for all Shares. Participants in DTC include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of Shares, you are not entitled to receive physical delivery of stock certificates or to have Shares registered in your name, and you are not considered a registered owner of Shares. Therefore, to exercise any right as an owner of Shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book entry or “street name” form.

FREQUENT PURCHASES AND REDEMPTIONS OF FUND SHARES 

The Board of Trustees has not adopted a policy of monitoring for other frequent trading activity because Shares are listed for trading on a national securities exchange.

DISTRIBUTION AND SERVICE PLAN 

The Funds have adopted a distribution and service plan (“Plan”) pursuant to Rule 12b-1 under the 1940 Act. Under the Plan, each Fund is authorized to pay distribution fees to the distributor and other firms that provide distribution and shareholder services (“Service Providers”). If a Service Provider provides these services, each Fund may pay fees at an annual rate not to exceed 0.25% of its average daily net assets, pursuant to Rule 12b-1 under the 1940 Act.

No distribution or service fees are currently paid by the Funds and will not be paid by the Funds unless authorized by the Board. There are no current plans to impose these fees. In the event Rule 12b-1 fees were charged, over time they would increase the cost of an investment in the Funds.

DIVIDENDS, OTHER DISTRIBUTIONS AND TAXES 

Shares are traded throughout the day in the secondary market on a national securities exchange on an intra-day basis and are created and redeemed in-kind and/or for cash in Creation Units at each day’s next calculated NAV. In-kind arrangements are designed to protect ongoing shareholders from the adverse effects on a Fund’s portfolio that could arise from frequent cash redemption transactions. In a conventional mutual fund, redemptions can have an adverse tax impact on taxable shareholders if the mutual fund needs to sell portfolio securities to obtain cash to meet net fund redemptions. These sales may generate taxable gains for the ongoing shareholders of the mutual fund, whereas the Shares’ in-kind redemption mechanism generally will not lead to a tax event for a Fund or its ongoing shareholders.

Ordinarily, dividends from net investment income, if any, are declared and paid quarterly by Sector Rotation, semi-annually by Thematic Innovation and semi-annually by International. Each Fund distributes its net realized capital gains, if any, to shareholders annually. Each Fund may also pay a special distribution at the end of a calendar year to comply with federal tax requirements.

No dividend reinvestment service is provided by the Funds. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Funds for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole Shares purchased in the secondary market.

Distributions in cash may be reinvested automatically in additional whole Shares only if the broker through whom you purchased Shares makes such option available.

Taxes 

As with any investment, you should consider how your investment in Shares will be taxed. The tax information in this prospectus is provided as general information. You should consult your own tax professional about the tax consequences of an investment in Shares.

Unless your investment in Shares is made through a tax-exempt entity or tax-deferred retirement account, such as an individual retirement account, you need to be aware of the possible tax consequences when:

• A Fund makes distributions,
• You sell your Shares listed on the Exchange, and
• You purchase or redeem Creation Units.

Taxes on Distributions 

Distributions from each Fund’s net investment income, including net short-term capital gains, if any, are taxable to you as ordinary income, except that the Fund’s dividends attributable to its “qualified dividend income” (i.e., dividends received on stock of most domestic and certain foreign corporations with respect to which the Fund satisfies certain holding period and other restrictions), if any, generally are subject to federal income tax for non-corporate shareholders who satisfy those restrictions with respect to their Shares at the rate for net capital gain. A part of a Fund’s dividends also may be eligible for the dividends-received deduction allowed to corporations -- the eligible portion may not exceed the aggregate dividends the Fund receives from domestic corporations subject to federal income tax (excluding REITs) and excludes dividends from foreign corporations -- subject to similar restrictions. However, dividends a corporate shareholder deducts pursuant to that deduction are subject indirectly to the federal alternative minimum tax.

In general, your distributions are subject to federal income tax when they are paid, whether you take them in cash or reinvest them in a Fund (if that option is available). Distributions reinvested in additional Shares through the means of a dividend reinvestment service, if available, will be taxable to shareholders acquiring the additional Shares to the same extent as if such distributions had been received in cash. Distributions of net long-term capital gains, if any, in excess of net short-term capital losses are taxable as long-term capital gains, regardless of how long you have held Shares.

Distributions in excess of a Fund’s current and accumulated earnings and profits are treated as a tax-free return of capital to the extent of your basis in Shares and as capital gain thereafter. A distribution will reduce the Fund’s NAV per Share and may be taxable to you as ordinary income or capital gain (as described above) even though, from an investment standpoint, the distribution may constitute a return of capital.

If you are a resident or a citizen of the U.S., by law, backup withholding at a 24% rate will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes on Exchange-Listed Share Sales 

Any capital gain or loss realized upon a sale of Shares is generally treated as long-term capital gain or loss if the Shares have been held for more than one year and as short-term capital gain or loss if the Shares have been held for one year or less. The ability to deduct capital losses from sales of Shares may be limited.

Taxes on Purchase and Redemption of Creation Units 

An Authorized Participant who exchanges securities for Creation Units generally will recognize a gain or a loss equal to the difference between the market value of the Creation Units at the time of the exchange and the sum of the exchanger’s aggregate basis in the securities surrendered plus the deposit of any specified cash payment (the “Cash Component”) it pays. An Authorized Participant who exchanges Creation Units for securities will generally recognize a gain or loss equal to the difference between the exchanger’s basis in the Creation Units and the sum of the aggregate market value of the securities received plus any cash equal to the difference between the NAV of the Shares being redeemed and the value of the securities. The Internal Revenue Service (“IRS”), however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing “wash sales” or for other reasons. Persons exchanging securities should consult their own tax advisor with respect to whether wash sale rules apply and when a loss might be deductible.

Any capital gain or loss realized upon redemption of Creation Units is generally treated as long-term capital gain or loss if the Shares have been held for more than one year and as short-term capital gain or loss if the Shares have been held for one year or less.

If an Authorized Participant purchases or redeems Creation Units, the Authorized Participant will be sent a confirmation statement showing how many Shares it purchased or sold and at what price. See “Tax Status” in the SAI for a description of the newly effective requirement regarding basis determination methods applicable to Share redemptions and the Funds’ obligation to report basis information to the IRS.

The foregoing discussion summarizes some of the possible consequences under current federal tax law of an investment in a Fund. It is not a substitute for personal tax advice. Consult your personal tax advisor about the potential tax consequences of an investment in the Shares under all applicable tax laws. See “Tax Status” in the SAI for more information.

Other Information

Continuous Offering

The method by which Creation Units of Shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Units of Shares are issued and sold by a Fund on an ongoing basis, a “distribution,” as such term is used in the Securities Act of 1933, as amended (the “Securities Act”), may occur at any point. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent Shares and sells Shares directly to customers or if it chooses to couple the creation of a supply of new Shares with an active selling effort involving solicitation of secondary market demand for Shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a characterization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are affecting transactions in Shares, whether or not participating in the distribution of Shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. As a result, broker-dealer firms should note that dealers who are not “underwriters” but are participating in a distribution (as contrasted with engaging in ordinary secondary market transactions) and thus dealing with the Shares that are part of an overallotment within the meaning of Section 4(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the Securities Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the Securities Act is only available with respect to transactions on a national exchange.

Dealers effecting transactions in Shares, whether or not participating in this distribution, are generally required to deliver a prospectus. This is in addition to any obligation of dealers to deliver a prospectus when acting as underwriters.
