Investment Objective

The Roundhill Cannabis ETF ("Cannabis ETF" or the "Fund") seeks capital growth.

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.

Shareholder Fees (fees paid directly from your investment)			None
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fee			0.39%
Distribution and/or Service (12b-1) Fees			0.00%
Other Expenses			0.00%
Acquired Fund Fees and Expenses			0.02%
Total Annual Fund Operating Expenses(1)			0.41%

(1) Total Annual Fund Operating Expenses do not correlate to the expense ratios in the Fund's Financial Highlights and financial statements because the Financial Highlights and financial statements include only the direct operating expenses incurred by the Fund and exclude Acquired Fund Fees and Expenses, which are the indirect costs of investing in other investment companies.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The 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:

1 Year:			$40			3 Years:			$130			5 Years:			$228			10 Years:			$516

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when 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, 2025, the Fund's portfolio turnover rate was 23% of the average value of its portfolio.

Principal Investment Strategy

The Fund is an actively managed exchange-traded fund ("ETF") that seeks to achieve its investment objective by investing primarily in exchange-listed equity securities and total return swaps intended to provide exposure to the cannabis and hemp ecosystem. The cannabis and hemp ecosystem encompasses businesses involved in the production, distribution and marketing of cannabis and hemp and products derived therefrom. Under normal circumstances, at least 80% of the Fund's net assets (plus any borrowings for investment purposes) will be invested in equity securities, including common stock and depositary receipts, of companies and real

1

estate investment trusts ("REITs") that derive at least 50% of their net revenue from, or invest a majority of their assets in, the cannabis and hemp ecosystem ("Cannabis Companies") and in derivatives that have economic characteristics similar to such securities.

The cannabis and hemp ecosystem spans a wide variety of sectors and industries including the agriculture, biotechnology, pharmaceuticals, real estate, retail, and finance sectors and industries. Cannabis Companies may be categorized within any of these sectors and industries and engage in the cannabis and hemp ecosystem in several ways, including the following:

• Production and/or distribution of cannabis-related and/or hemp-related products, including those for medical (including research and development) and therapeutic uses;

• Business to business providers for the cannabis and hemp ecosystem, including technology, agricultural technology, real estate, financing, and commercial services companies; and/or

• Business to consumer providers for the cannabis industry, including technology and media, consumption devices/mechanisms, and retailing companies.

Generally, the terms "marijuana" and "cannabis" are used interchangeably and refer to products derived from the cannabis plant, including cannabinoids. Cannabinoids are the chemical compounds secreted by cannabis plants. Cannabinoids can also be synthetically produced chemical compounds and used in lawful research and development of prescription drugs or other products utilizing cannabinoids as an active ingredient. Hemp refers to the industrial/commercial use of the cannabis stalk and seed for textiles, foods, papers, body care products, detergents, plastics and building materials. The Fund will not invest directly in or hold ownership in any companies that engage in cannabis-related business unless such business is permitted by national and local laws of the relevant jurisdiction, including U.S. federal and state laws.

The Adviser uses qualitative factors, such as publicly available company filings, publicly available research, and press releases, to identify a universe of Cannabis Companies by determining a company's thematic relevance to the cannabis and hemp ecosystem. Based on its analysis, each Cannabis Company selected for the Fund will be assigned a weight that generally will be on a modified market capitalization basis, to seek to create a portfolio that reflects companies that contribute to the cannabis and hemp ecosystem through a variety of cannabis-related products and services.

The Fund may invest in securities issued by small, medium and large capitalization companies operating in emerging and developed market countries. The Fund may purchase equity securities that trade on U.S. or non-U.S. securities exchanges and American Depositary Receipts ("ADRs") or Global Depositary Receipts ("GDRs"). The Fund may invest in both equity and mortgage REITs. Further, the Fund may utilize derivative instruments that are available or traded on the over-the-counter ("OTC") market or listed and traded on an exchange to obtain expose to Cannabis Companies. The Fund anticipates investing primarily in total return swaps to obtain such exposure. A total return swap is a contract in which one party agrees to make periodic payments to another party based on the change in market value of the assets underlying the contract, which may include a specified security, basket of securities, or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets.

The Fund expects to concentrate at least 25% of its investments in the Pharmaceuticals, Biotechnology & Life Sciences Industry Group as defined by the Global Industry Classification (GICS®) or other similar categorization scheme. This level of exposure may change over time and in response to changes in the cannabis and hemp ecosystem. Additionally, the Fund may invest in (1) U.S. Government securities, such as bills, notes and bonds issued by the U.S. Treasury; (2) money market funds; and/or (3) short-term bond ETFs.

Principal Investment Risks

The principal risks of investing in the Fund are summarized below. 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 asset value ("NAV"), trading price, yield, total return and/or ability to meet its investment objective. The following risks could affect the value of your investment in the Fund:

• United States Regulatory Risks of the Cannabis Industry. The possession and use of marijuana, even for medical purposes, is illegal under federal and certain states' laws, which may negatively impact the value of the Fund's investments. Use of marijuana is regulated by both the federal government and state governments, and state and federal laws regarding marijuana often conflict. Even in those states in which the use of marijuana has been legalized, its possession and use remains a violation of federal law. Federal law criminalizing the use of marijuana pre-empts state laws that legalize its use for medicinal and recreational purposes. Actions by federal agencies, such as increased enforcement of current federal marijuana laws and the prosecution of nonviolent federal drug crimes by the U.S. Department of Justice ("DOJ"), could produce a chilling effect on the industry's growth and discourage banks from expanding their services to Cannabis Companies where such services are currently limited. Any of these outcomes would negatively affect the profitability and value of the Fund's investments and even its ability to pursue its stated

2

investment objective. The conflict between the regulation of marijuana under federal and state law creates volatility and risk for all Cannabis Companies.

Because marijuana is a Schedule I controlled substance under the Controlled Substances Act ("CSA"), meaning that it has a high potential for abuse, has no currently "accepted medical use" in the United States, lacks accepted safety for use under medical supervision, and may not be prescribed, marketed or sold in the United States, few drug products containing cannabis or cannabis extracts have been approved for use by the Food and Drug Administration ("FDA") or obtained registrations for commercial production from the U.S. Drug Enforcement Agency ("DEA"), and there is no guarantee that such products will ever be legally produced or sold in the U.S. Cannabis Companies in the U.S. that engage in research, manufacturing, distributing, importing or exporting, or dispensing controlled substances must be registered (licensed) to perform these activities and have the security, control, recordkeeping, reporting and inventory mechanisms required by the DEA to prevent drug loss and diversion. Failure to obtain the necessary registrations or comply with necessary regulatory requirements may significantly impair the ability of certain companies in which the Fund invests to pursue medical marijuana research or to otherwise cultivate, possess or distribute marijuana. In addition, because cannabis is a Schedule I controlled substance, Section 280E of the Internal Revenue Code of 1986 ("Code") applies by its terms to the purchase and sale of medical-use cannabis products and provides that no deduction or credit is allowed for expenses incurred during a taxable year "in carrying on any trade or business if such trade or business (or the activities which comprise such trade or business) consists of trafficking in controlled substances (within the meaning of Schedules I and II of the CSA) which is prohibited by federal law or the law of any state in which such trade or business is conducted." The disallowance of such tax deductions will likely affect the value of Cannabis Companies.

On December 18, 2025, the President of the United States issued an Executive Order directing relevant federal agencies to advance medical marijuana and cannabidiol research and complete the administrative process to reschedule marijuana from Schedule I to Schedule III under the CSA. Rescheduling to Schedule III would reflect an accepted medical use under federal law and could reduce certain regulatory and tax burdens applicable to cannabis-related businesses. However, the Executive Order does not itself change marijuana's legal status and any rescheduling remains subject to formal rulemaking, potential delay, modification, or legal challenge. There can be no assurance that rescheduling will be completed or that it will result in reduced legal, regulatory, or financial risks for cannabis securities.

• Non-U.S. Regulatory Risks of the Cannabis Industry. Laws and regulations related to the possession, use (medical and recreational), sale, transport and cultivation of marijuana vary throughout the world, and the Fund will only invest in non-U.S. Cannabis Companies if such companies are operating legally in the relevant jurisdiction. Even if a company's operations are permitted under current law, they may not be permitted in the future, in which case such company may not be in a position to carry on its operations in its current locations. Additionally, controlled substance legislation differs between countries and legislation in certain countries may restrict or limit the ability of certain companies in which the Fund invests to sell their products.

• Operational Risks of the Cannabis Industry. Companies involved in the cannabis industry face intense competition, may have limited access to the services of banks, may have substantial burdens on company resources due to litigation, complaints or enforcement actions, and are heavily dependent on receiving necessary permits and authorizations to engage in medical cannabis research or to otherwise cultivate, possess or distribute cannabis. Because the cultivation, possession, and distribution of cannabis is in all circumstances illegal under United States federal law, federally regulated banking institutions may be unwilling to make financial services available to growers and sellers of cannabis.

• United States Regulatory Risks of Hemp. "Hemp," as defined in the Agriculture Improvement Act of 2018 (the "Farm Bill"), refers to cannabis plants with a tetrahydrocannabinol ("THC") concentration of not more than 0.3% on a dry weight basis, as well as derivatives thereof, whereas "marijuana" refers to all other cannabis plants and derivatives thereof. The Farm Bill effectively removes hemp from the list of controlled substances and allows states to regulate its production, commerce and research with approval from the United States Department of Agriculture ("USDA"). Certain portfolio holdings may sell dietary supplements and/or foods containing CBD within the United States. While the Farm Bill removes hemp and hemp-derived products from the controlled substances list under the CSA, it does not legalize CBD in every circumstance. CBD, depending on the source from which it was derived, can still be classified as a Schedule I substance under the CSA's definition of "marihuana." The exception for CBD from the definition of "marihuana" only applies if the CBD is derived from "hemp." U.S. federal law also requires that: (i) the hemp is produced by a licensed producer; and (ii) in a manner consistent with the applicable federal and state regulations. CBD and other cannabinoids produced from marijuana as defined by the CSA remain an illegal Schedule I substance under federal law. In addition, many state laws include all CBD within definitions of marijuana and some states have policies or laws that otherwise prohibit or restrict CBD sales.

The Farm Bill delegates to the FDA responsibility for regulating products containing hemp or derivatives thereof (including CBD) under the Federal Food, Drug, and Cosmetic Act (the "FD&C"). Under the FD&C, if a substance (such as CBD) is an active ingredient in a drug product that has been approved by the FDA, then the substance cannot be sold in dietary supplements or foods without FDA approval, unless the substance was marketed as a dietary supplement or as a conventional food before the drug was approved or before the new drug investigations were authorized. The FDA has publicly taken the position that CBD

3

cannot be sold in dietary supplements or foods because CBD is an active ingredient in an FDA-approved drug. Future federal and/or state laws or regulations could drastically curtail permissible uses of hemp, which could have an adverse effect of the value of the Fund's investments in companies with business interests in hemp and hemp-based products.

The remaining principal risks are presented in alphabetical order. Each risk summarized below is considered a "principal risk" of investing in the Fund, regardless of the order in which it appears.

• Cash Transaction Risk. The Fund expects to effect certain of its creations and redemptions for cash, rather than in-kind securities. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. The use of cash creations and redemptions may also cause the Fund's shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the Fund's NAV. Further, effecting purchases and redemptions primarily in cash may cause the Fund to incur certain costs, such as portfolio transaction costs. These costs can decrease the Fund's NAV if not offset by an authorized participant transaction fee.

• Concentration Risk. The Fund expects to have concentrated ( i.e. , invest more than 25% of its net assets) investment exposure in the Pharmaceuticals, Biotechnology & Life Sciences Industry Group. As a result, the Fund is more vulnerable to adverse market, economic, regulatory, political or other developments affecting those industries, or groups of related industries, than a fund that invests its assets in a more diversified manner.

◦ Pharmaceuticals, Biotechnology & Life Sciences Industry Group Risk . Companies in the Pharmaceuticals, Biotechnology & Life Sciences Industry Group can be significantly affected by, among other things, government approval of products and services, government regulation and reimbursement rates, product liability claims, patent expirations and protection, and intense competition.

• Counterparty Risk. The Fund may use swap agreements to gain exposure to a particular group of securities, index, asset class or other reference asset without actually purchasing those securities or investments, to hedge a position, or for other investment purposes. Through these investments and related arrangements ( e.g., prime brokerage or securities lending arrangements or derivatives transactions), the Fund is exposed to credit risks that the counterparty may be unwilling or unable to make timely payments or otherwise to meet its contractual obligations. If the counterparty becomes bankrupt or defaults on (or otherwise becomes unable or unwilling to perform) its payment or other obligations to the Fund, the Fund may not receive the full amount that it is entitled to receive or may experience delays in recovering the collateral or other assets held by, or on behalf of, the counterparty. If this occurs, the value of your shares in the Fund will decrease.

• 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 (defined below) 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"), the Fund's primary listing exchange, or the issuers of securities in which the Fund invests have the ability to disrupt and negatively affect the Fund's business operations, including the ability to purchase and sell Shares, potentially resulting in financial losses to the Fund and its shareholders.

• Depositary Receipt Risk . Depositary receipts, including ADRs and GDRs, 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. Because the Underlying Shares trade on foreign exchanges that may be closed when the Fund's primary listing exchange is open, the Fund may experience premiums and discounts greater than those of funds without exposure to such Underlying Shares.

• Derivatives Risk. The Fund intends to invest in total return swaps, which are a type of derivative. Derivatives may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other investments, including risks relating to leverage, imperfect correlations with underlying investments or the Fund's other portfolio holdings, high price volatility, lack of availability, counterparty credit, liquidity, valuation and legal restrictions. Their use is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities

4

transactions. The Fund's use of derivatives to obtain short exposure, if any, may result in greater volatility of the Fund's NAV per share. If the Adviser and Sub-Adviser are incorrect about their expectations of market conditions, the use of derivatives could also result in a loss, which in some cases may be unlimited. In addition, the Fund's use of derivatives may cause the Fund to realize higher amounts of short-term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments. Some of the derivatives in which the Fund invests may be traded (and privately negotiated) in the OTC market. OTC derivatives are subject to heightened counterparty credit, liquidity and valuation risks. Certain risks also are specific to the derivatives in which the Fund invests.

◦ Swap Agreements Risk. Swap agreements are contracts among the Fund and a counterparty to exchange the return of the pre-determined underlying investment (such as the rate of return of the underlying index). Swap agreements may be negotiated bilaterally and traded OTC between two parties or, for certain standardized swaps, must be exchange-traded through a futures commission merchant and/or cleared through a clearinghouse that serves as a central counterparty. Risks associated with the use of swap agreements are different from those associated with ordinary portfolio securities transactions, due in part to the fact they could be considered illiquid and many swaps trade on the OTC market. Swaps are particularly subject to counterparty credit, correlation, valuation, liquidity and leveraging risks. While exchange trading and central clearing are intended to reduce counterparty credit risk and increase liquidity, they do not make swap transactions risk-free. Additionally, applicable regulators have adopted rules imposing certain margin requirements, including minimums, on OTC swaps, which may result in the Fund and its counterparties posting higher margin amounts for OTC swaps, which could increase the cost of swap transactions to the Fund and impose added operational complexity.

• Emerging and Developing Markets Risk. The Fund's direct or indirect investments in securities of issuers in emerging and developing market countries are subject to all of the risks of foreign investing generally, and have additional heightened risks due to a lack of established legal, political, business, and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation, or currency devaluation.

• Equity Securities 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 susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. Preferred stocks are subject to the risk that the dividend on the stock may be changed or omitted by the issuer, and that participation in the growth of an issuer may be limited.

• ETF Risks. The Fund is an ETF, and, as a result of its structure, it is exposed to the following risks:

◦ Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. 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 Cboe BZX Exchange, 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.

5

• Fixed Income Risk. Fixed income securities are subject to call, credit, extension, and interest rate risk.

◦ Call Risk . During periods of falling interest rates, an issuer of a callable bond held by the Fund may "call" or repay the security before its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund's income.

◦ Credit Risk . An issuer of a fixed income security, such as a corporate bond, may be unable or unwilling to make interest and principal payments when due. The Fund also is subject to the related risk that the value of a fixed income security may decline because of concerns about the issuer's creditworthiness. Credit risk is heightened to the extent the Fund invests in below investment-grade securities, which also are referred to as high-yield securities or junk bonds.

◦ Extension Risk . During periods of rising interest rates, certain debt obligations will be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in the Fund's income and potentially in the value of the Fund's investments.

◦ Income Risk. The Fund's income may decline if interest rates fall. The risk of decline in income is heightened when fixed income instruments held by the Fund have floating or variable interest rates.

◦ Interest Rate Risk . Interest rate risk is the risk that interest rates rise and fall over time. For example, the value of fixed-income securities generally decrease when interest rates rise, which may cause the Fund's value to decrease. Also, investments in fixed-income securities with longer maturities fluctuate more in response to interest rate changes. Variable and floating rate securities may increase or decrease in value in response to changes in interest rates, although generally to a lesser degree than fixed-income securities.

◦ Prepayment Risk. The risk that changes in interest rates, credit spreads or other factors will result in the call (repayment) of a debt instrument before it is expected. The Fund may have to invest the proceeds in lower yielding securities or that expectations of such early call will negatively impact the market price of the security.

• 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.

• Investment Company Risk. The risks of investing in investment companies, such as ETFs, typically reflect the risks of the types of instruments in which the investment companies invest. By investing in another investment company, the Fund becomes a shareholder of that investment company and bears its proportionate share of the fees and expenses of the other investment company. The Fund may be subject to statutory limits with respect to the amount it can invest in other ETFs, which may adversely affect the Fund's ability to achieve its investment objective. ETFs may be less liquid than other investments, and thus their share values more volatile than the values of the investments they hold. Investments in ETFs are also subject to the "ETF Risks" described above.

• Limited Issuer Risk. Because the Fund may invest in a limited number of issuers, it is subject to the risk that the value of the Fund's portfolio may decline due to a decline in value of the equity securities of particular issuers. The value of an issuer's equity securities may decline for reasons directly related to the issuer, such as management performance and reduced demand for the issuer's goods or services.

• Liquidity and Valuation Risk. It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund's NAV, causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of portfolio investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time.

6

• Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser's and Sub-Adviser's success or failure to implement investment strategies for the Fund. The Sub-Adviser's evaluations and assumptions regarding issuers, securities, and other factors may not successfully achieve the Fund's investment objective given actual market conditions.

• Market Capitalization Risk.

◦ 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.

◦ Mid-Capitalization Investing Risk. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large-capitalization stocks or the stock market as a whole.

◦ 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. In addition, government actions or interventions (including, but not limited, to the threat or imposition of tariffs, trade restrictions, currency restrictions or similar actions) as well as developments related to economic, political (including geopolitical), social, public health, market, extreme weather, natural or man-made disasters, or other conditions or events have in the past and may in the future result in volatility in financial markets and reduced liquidity in equity, credit, and/or debt markets, which could adversely impact the Fund and its investments and their value and performance. 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.

• Money Market Instrument Risk. The Fund may use a variety of money market instruments for cash management purposes, including money market funds, depositary accounts and repurchase agreements. Money market funds may be subject to credit risk with respect to the debt instruments in which they invest. Depository accounts may be subject to credit risk with respect to the financial institution in which the depository account is held. Money market instruments may lose money.

• Real Estate Companies Risk. The Fund invests in real estate companies, including REITs and real estate holdings companies, which will expose investors to the risks of owning real estate directly, as well as to the risks that relate specifically to the way in which such companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments. The U.S. real estate market may experience and has, in the past, experienced a decline in value, with certain regions experiencing significant losses in property values. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund's volatility and losses. Exposure to such real estate may adversely affect Fund performance.

• REITs Risk. REITs are subject to the risks associated with investing in the securities of real property companies. In particular, REITs may be affected by changes in the values of the underlying properties that they own or operate. Residential/diversified REITs and commercial equity REITs may be affected by changes in the value of the underlying property owned by the trusts, while mortgage REITs may be affected by the quality of any credit extended. Further, REITs are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency and, as a result, are particularly reliant on the proper functioning of capital markets. A variety of economic and other factors may adversely affect a lessee's ability to meet its obligations to a REIT. In the event of a default by a lessee, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments. In addition, a REIT could fail to qualify for favorable regulatory treatment.

• 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.

7

◦ Health Care Sector Risk . Health care companies are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines, and an increased emphasis on the delivery of healthcare through outpatient services. Health care companies are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of the companies. Health care companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies, or other market developments. Many new products in the health care field require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.

• Securities Lending Risk . To the extent the Fund engages in securities lending, there are certain risks associated with securities lending, including the risk that the borrower may fail to return the securities on a timely basis or even the loss of rights in the collateral deposited by the borrower, if the borrower should fail financially. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. As a result, the Fund may lose money.

• Tax Risk. In order to qualify for the favorable tax treatment generally available to a regulated investment company ("RIC"), the Fund must satisfy certain diversification and other requirements. In particular, at each quarter end (a) at least 50% of the value of the Fund's total assets must generally be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited, in respect to any one issuer, to an amount not greater than 5% of the value of the Fund's total assets and that does not represent more than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of the Fund's total assets is invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer or the securities (other than the securities of another RIC) of two or more issuers that the Fund controls and which are engaged in the same or similar trades or businesses or related trades or businesses, or the securities of one or more qualified publicly traded partnerships (the "Diversification Requirement"). The Fund anticipates gaining exposure to seven Underlying Issuers. To satisfy the Diversification Requirement, the Fund will gain exposure to the Underlying Issuers by entering into swap agreements and/or forward contracts or by investing in equity securities of an Underlying Issuer. The determination of the value and the identity of the issuer of derivatives, such as swap agreements and forward contracts, is often unclear for purposes of the Diversification Requirement described above. Although the Fund intends to carefully monitor its investments in derivatives to ensure that it is adequately diversified under the Diversification Requirement, there are no assurances that the Internal Revenue Service ("IRS") will agree with the Fund's determination of the issuer and valuation of such derivatives under the Diversification Requirement with respect to such derivatives. The Adviser's and the Sub-Adviser's efforts to satisfy the Fund's Diversification Requirement may compromise their ability to implement the Fund's investment strategy as effectively as they might otherwise have been able to in the absence of such a requirement. If the Fund fails to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level (unless certain relief provisions are available.) The resulting taxes could substantially reduce the Fund's net assets and the amount of income available for distribution to shareholders. In addition, in order to requalify as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions to its shareholders. In addition, the Fund's use of derivatives may cause the Fund to realize higher amounts of short-term capital gains or otherwise affect the Fund's ability to pay out dividends subject to preferential rates or the dividends received deduction, thereby increasing the amount of taxes payable by some shareholders. Please see the section entitled "Federal Income Taxes - Taxation of the Funds" in the SAI for more information.

• U.S. Government Securities Risk. U.S. government securities may or may not be backed by the full faith and credit of the U.S. government. U.S. government securities are subject to the risks associated with fixed-income and debt securities, particularly interest rate risk and credit risk.

Performance

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.

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.

Portfolio Management

Adviser			Roundhill Financial Inc.
Sub-Adviser			Exchange Traded Concepts, LLC (the "Sub-Adviser")
Portfolio Managers			William Hershey and Timothy Maloney, each a portfolio manager for the Adviser, and Andrew Serowik, Todd Alberico, Gabriel Tan and Brian Copper, each a portfolio manager for the Sub-Adviser, have been portfolio managers of the Fund since its inception in April 2022. David Mazza, also a portfolio manager for the Adviser, has been a portfolio manager of the Fund since March 2025.

Purchase and Sale of Shares

The Fund issues and redeems Shares at NAV only in large blocks known as "Creation Units," which only APs (typically, broker-dealers) may purchase or redeem. The Fund generally issues and redeems Creation Units in exchange for a portfolio of securities and/or a designated amount of U.S. cash.

Shares are listed on the Exchange, and individual Shares may only be bought and sold in the secondary market through a broker or dealer at market prices, rather than NAV. Because Shares trade at market prices rather than NAV, Shares may trade at a price greater than NAV (premium) or less than NAV (discount).

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."

Tax Information

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.

Financial Intermediary Compensation

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.
