Before you invest, you may want to review the Fund’s prospectus and statement of additional information (“SAI”), which contain more information about the Fund and its risks. The current prospectus and SAI dated April 30, 2024, are incorporated by reference into this Summary Prospectus. You can find the Fund’s prospectus, reports to shareholders, and other information about the Fund online at https://www.roundhillinvestments.com/etf/BETZ. You can also get this information at no cost by calling 1-800-617-0004 or by sending an e-mail request to ETF@usbank.com.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. For the fiscal year ended December 31, 2023, the Fund’s portfolio turnover rate was 64% of the average value of its portfolio.

The Index was developed by Morningstar, Inc. (the “Index Provider”) and is designed to provide pure exposure to sports and online betting themes. In order to achieve such exposure, the Index is comprised of common stock (or corresponding American Depositary Receipts (“ADRs”) or Global Depositary Receipts (“GDRs”)) of domestic and foreign sports and online betting (a/

Stocks included in the Index must (i) receive a score 1 or higher from the Index Provider on either a Sports Betting or iGaming theme, (ii) have a free-float market capitalization of at least $100 million (USD), and (iii) have a minimum three-month average daily traded value of $250,000 (USD). The Index Provider will assign a score of 1 or higher to a company that the Index Provider has determined (a) is a producer of related goods or services or a supplier of those producers, and (b) is highly likely to enjoy a material net profit increase from its exposure to such Sports Betting or iGaming theme over the next five years. The Index Provider estimates the percent revenue a company will derive from its exposure to each theme at a point in time five years forward, which translates to the following scores: 0 = less than 10% revenue; 1 = 10% - 25% of revenue for a producer or supplier; 2 = 25% - 50% of revenue for a producer or supplier; 3 = greater than 50% of revenue for a supplier; 4 = greater than 50% revenue for a producer. Scores are reviewed by the Index Provider’s steering committee for quality control and to ensure consistency.

Index components are weighted in proportion to both their combined theme score and their free-float market capitalization, subject to capping constraints. Companies with higher combined theme scores are allocated a greater weight in the Index. Index components are capped to ensure that no Index component has a weight greater than 10% and the sum of components with weights greater than or equal to 5% cannot exceed 40%.

The Fund will generally invest all, or substantially all, of its assets in the component securities of the Index, but also may invest in investments that provide comparable exposure, including but not limited to depositary receipts representing Index components and investments in other exchange-traded funds (“ETFs”). Under normal circumstances, at least 80% of the Fund’s net assets (plus borrowings for investment purposes) will be invested in securities issued by Sports Betting and iGaming Companies.

The Fund will generally use a “replication” strategy to achieve its investment objective, meaning the Fund generally will invest in all of the component securities of the Index in approximately the same proportions as in the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Index as a whole, when Exchange Traded Concepts, LLC (the “Sub-Adviser”), the Fund’s sub-adviser, believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index component becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).

The Fund also may invest in securities or other investments not included in the Index, but which the Sub-Adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).

To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. As of March 31, 2024, the Index was concentrated in the Casinos and Gaming Sub-Industry, a separate industry within the Consumer Discretionary Sector.

The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with the risks of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net

•Associated Risks of iGaming and Sports Betting Companies. The iGaming and sports betting industry is characterized by an increasingly high degree of competition among a large number of participants including from participants performing illegal activities or unregulated companies. Expansion of iGaming and sports betting in other jurisdictions (both regulated and unregulated) could increase competition with traditional betting companies, which could have an adverse impact on their financial condition, operations and cash flows. In a broader sense, iGaming and sports betting companies face competition from all manner of leisure and entertainment activities, including shopping, athletic events, television and movies, concerts and travel. In addition, established jurisdictions could award additional licenses or permit the expansion or relocation of existing sports betting companies. These companies also may be subject to increasing regulatory constraints, particularly with respect to cybersecurity and privacy. In addition to the costs of complying with such constraints, the unintended disclosure of confidential information, whether because of an error or a cybersecurity event, could adversely affect the reputation, profitability and value of these companies.

◦Casinos & Gaming Industry. The Casinos & Gaming Industry includes owners and operators of casinos and gaming facilities, and companies providing lottery and betting services. The Casinos & Gaming Industry is highly competitive and companies operating in the Casinos & Gaming Industry rely heavily on consumer spending and the availability of disposable income for success. In addition, the Casinos & Gaming Industry may be negatively affected by changes in economic conditions, consumer tastes and discretionary income levels, technological developments, limited financial resources, competition from competing entertainment options, and competition for key personnel. Casinos are closely tied to the travel and tourism industry and are particularly sensitive to economic shutdowns and mitigation strategies, such as the COVID-19 pandemic. In addition, Casinos & Gaming Industry companies are highly regulated, and state and federal legislative or regulatory changes and licensing issues (as well as the laws of other countries) can significantly impact their ability to operate in certain jurisdictions. The Casinos & Gaming Industry is a sub-industry of the Hotels, Restaurants & Leisure Industry within the Consumer Discretionary Sector.

•Currency Exchange Rate Risk. The Fund may invest in investments denominated in non-U.S. currencies or in securities that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

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

•Depositary Receipt Risk. Depositary receipts, including ADRs, involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary receipts listed on U.S. exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares.

•Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, sectors or companies in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

liquidity providers in the marketplace. Shares may trade at a material discount to NAV and possibly face delisting if either: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

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

◦Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums or discounts greater than those of ETFs that invest in and hold only securities and other investments that are listed and trade in the U.S.

◦Trading Risk. Although Shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than the Shares.

•Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. These include risks of adverse changes in foreign economic, political, regulatory and other conditions, or changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges). The securities of some foreign companies may be less liquid and, at times, more volatile than securities of comparable U.S. companies. There may be less information publicly available about a non-U.S. issuer than a U.S. issuer. Non-U.S. issuers may be subject to different accounting, auditing, financial reporting and investor protection standards than U.S. issuers. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. With respect to certain countries, there is the possibility of government intervention and expropriation or nationalization of assets. Because legal systems differ, there also is the possibility that it will be difficult to obtain or enforce legal judgments in certain countries. Since foreign exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. Conversely, Shares may trade on days when foreign exchanges are closed. Each of these factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

•Illiquidity Risk. Illiquidity risk exists when particular investments are difficult to purchase or sell, possibly preventing the Fund from selling these illiquid investments at an advantageous price or at the time desired. A lack of liquidity may also cause the value of investments to decline. Illiquid investments may also be difficult to value.

•Index Provider Risk. There is no assurance that the Index Provider, or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. The Adviser relies upon the Index Provider and its agents to compile, determine, construct, reconstitute, rebalance, compose, calculate (or arrange for an agent to calculate), and disseminate the Index accurately. Any losses or costs associated with errors made by the Index Provider or its agents generally will be borne by the Fund and its shareholders.

◦Large-Capitalization Investing Risk. The securities of large-capitalization companies may be relatively mature compared to smaller companies and, therefore, subject to slower growth during times of economic expansion. Large-capitalization companies also may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

◦Small-Capitalization Investing Risk. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.

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

•Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a lesser number of issuers than if it was a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a lesser number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

•Passive Investment Risk. The Fund is not actively managed and its Sub-Adviser would not sell an investment designed to provide exposure to the Index or a constituent holding of the Index due to current or projected underperformance of a security industry or sector unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a rebalancing of the Index as addressed in the Index methodology.

•Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. The Fund may invest a significant portion of its assets in the following sectors and, therefore, the performance of the Fund could be negatively impacted by events affecting each of these sectors.

◦Consumer Discretionary Sector Risk. Consumer discretionary companies are companies that provide non-essential goods and services, such as retailers, media companies and consumer services. These companies manufacture products and provide discretionary services directly to the consumer, and the success of these companies tied closely to the performance of the overall domestic and international economy, interest rates, competition and consumer confidence.

•Tracking Error Risk. As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.

The performance information presented below provides some indication of the risks of investing in the Fund by showing the extent to which the Fund’s performance can change from year to year and over time. The bar chart below shows the Fund’s performance for calendar years ended December 31. The table illustrates how the Fund’s average annual returns for the 1 year and since inception periods compare with those of the Index and the Solactive GBS Global Markets All Cap USD Index TR, which reflects a broad measure of market performance. The Fund’s past performance, before and after taxes, does not necessarily indicate how it will perform in the future. The Fund’s investment objective and principal investment strategies changed on October 2, 2023 to track the current Index. Prior to October 2, 2023, the Fund sought to track the total return performance, before fees and expenses, of the Roundhill Sports Betting & iGaming Index. Therefore, the performance and average annual total returns shown for periods prior to October 2, 2023 may have differed had the Fund’s current investment objective and principal investment strategies been in effect during those periods. Updated performance information is available on the Fund’s website at www.roundhillinvestments.com/etf/BETZ.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates during the period covered by the table above and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Shares through tax-deferred arrangements such as an individual retirement account (“IRA”) or other tax-advantaged accounts. In certain cases, the figure representing “Return After Taxes on Distributions and Sale of Shares” may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor.

An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (the “bid” price) and the lowest price a seller is willing to accept for Shares (the “ask” price) when buying or selling Shares in the secondary market. The difference in the bid and ask prices is referred to as the “bid-ask spread.”

The Fund’s distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is held in an IRA or other tax-advantaged account. Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the Adviser or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange-traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.
