SUMMARY PROSPECTUS

January 25, 2021

Before you invest, you may want to review the Fund’s Prospectus, which contains more information about the Fund and its risks. The Fund’s Prospectus and Statement of Additional Information, both dated January 25, 2021, are incorporated by reference into this Summary Prospectus. You can obtain these documents and other information about the Fund online at www.mainmgtetfs.com. You can also obtain these documents at no cost by calling 1-866-383-9778 or by sending an email request to OrderMainMgtETFs@UltimusFundSolutions.com. Shares of the Fund are listed and traded on Cboe BZX Exchange, Inc. (the “Exchange”).

Investment Objective: 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 and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.65%
Distribution and Service (12b-1) Fees	0.00%
Other Expenses(1)	0.67%
Acquired Fund Fees and Expenses(2)	0.66%
Total Annual Fund Operating Expenses	1.98%
Fee Waiver and Reimbursement(2)(3)	(0.33)%
Total Annual Fund Operating Expenses After Fee Waiver	1.65%

(1) Estimated for the current fiscal year.

(2) Acquired Fund Fees and Expenses are the indirect costs of investing in other investment companies. The operating expenses in this fee table will not correlate to the expense ratio in the Fund’s financial highlights because the financial statements include only the direct operating expenses incurred by the Fund.

(3) The Fund’s adviser, Main Management ETF Advisors, LLC (the “Adviser”), has contractually agreed to reduce its fees and/or absorb expenses of the Fund, until at least July 31, 2031, to insure that total annual fund operating expenses after fee waiver and/or reimbursement (exclusive of any front-end or contingent deferred loads, taxes, brokerage fees and commissions, borrowing costs (such as interest and dividend expense on securities sold short), acquired fund fees and expenses, fees and expenses associated with investments in other collective investment vehicles or derivative instruments (including for example option and swap fees and expenses), or extraordinary expenses such as litigation (which may include indemnification of Fund officers and Trustees, contractual indemnification of Fund service providers (other than the Adviser))) will not exceed 0.99% of the Fund’s average daily net assets. These fee waivers and expense reimbursements are subject to possible recoupment from the Fund in future years (within the three years from the time the fees were waived or reimbursed), if, after such recoupment is taken into account, the expense ratio does not exceed the lesser of the foregoing expense limits or those in place at the time of recapture. This agreement may be terminated only by the ‘Board of Trustees on 60 days’ written notice to the Adviser.

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:

1 Year	3 Years	5 Years	10 Years
$168	$529	$897	$1,955

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 theme-based equity exchange traded funds (“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 we have seen in the past from other 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 will 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 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 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.

2 

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 downsized 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 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 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,” 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.

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 the special risks, including:

• Not Individually Redeemable: Shares are not individually redeemable to retail investors and may be redeemed by the ETF only to Authorized Participants at NAV in large blocks known as “Creation Units.” An Authorized Participant may incur brokerage costs purchasing enough Shares to constitute a Creation Unit.
• Trading Issues: An active trading market for the 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. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.
• 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.

• In times of market stress, market makers may step away from their role market making in the Shares of ETFs and in executing trades, which can lead to differences between the market value of Shares and an ETF’s NAV.
• To the extent Authorized Participants exit the business or are unable to process creations or redemptions and no other Authorized Participant can step in to do so, there may be a significantly reduced trading market in the Shares, which can lead to differences between the market value of Shares and an ETF’s NAV.
• 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.
• When all or a portion of an ETFs underlying securities trade in a market that is closed when the market for the Shares is open, there may be changes from the last quote of the closed market and the quote from an ETF’s domestic trading day, which could lead to differences between the market value of the Shares and an ETF’s NAV.
• In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of an ETF’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and an ETF’s NAV.

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.

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.

Management Risk: The portfolio manager’s 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, pandemics, epidemics, terrorism, 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. The current novel coronavirus (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, has 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.

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.

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: 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, 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: The Fund will issue and redeem Shares at NAV only in large blocks of 10,000 Shares (each block of Shares is called a “Creation Unit”) to Authorized Participants who have entered into agreements with the Fund’s distributor. Creation Units are issued and redeemed for cash and/or in-kind for securities. Individual Shares of the Fund may only be purchased and sold in secondary market transactions through a broker dealer. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Shares of the Fund are listed for trading on the Exchange and trade at market prices rather than NAV. Shares of the Fund 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.
