Roundhill S&P Dividend Monarchs ETF

Investment Objective

The Fund seeks to track the total return performance, before fees and expenses, of the S&P Dividend Monarchs Index (the “Index”).

Fees and Expenses of the Fund

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

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

Management Fees⁽¹⁾	0.__%
Distribution and Service (12b-1) Fees	0.00%
Other Expenses⁽²⁾	0.00%
Total Annual Fund Operating Expenses	0.__%

(1)

The investment advisory agreement between the Trust and Roundhill Financial Inc. (“Roundhill”) provides that Roundhill will pay all operating expenses of the Fund, except Roundhill’s management fees, interest charges on any borrowings, dividends and other expenses on securities sold short, taxes, brokerage commissions and other expenses incurred in placing orders for the purchase and sale of securities and other investment instruments, acquired fund fees and expenses, accrued deferred tax liability, extraordinary expenses, and distribution fees and expenses paid by the Trust under any distribution plan.

(2)

“Other Expenses” are estimates based on the expenses the Fund expects to incur for the current fiscal year.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell all of your Fund Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Year 1	Year 3
$_______	$_______

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the example, affect the Fund’s performance. Because the Fund has not yet commenced operations, portfolio turnover information is unavailable at this time.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its total assets in the common stock and real estate investment trusts (“REITs”) comprising the Index. The Fund, using a full replication approach, attempts to provide, before fees and expenses, the total return performance of the Index. The Index is owned and was developed by S&P Dow Jones Indices, LLC a division of S&P Global (“SPDJI” or the “Index Provider”). The Index Provider reserves the right to make exceptions when applying the methodology if the need arises. In addition, the Index Provider may revise Index policy covering rules for selecting companies, treatment of dividends, share counts or other matters. Roundhill Financial Inc. serves as the Fund’s investment adviser (“Roundhill” or the “Adviser”) and Exchange Traded Concepts, LLC serves as the Fund’s investment sub-adviser (“ETC” or the “Sub-Adviser”).

The Index measures the performance of companies that have followed a policy of consistently increasing dividends every year for at least 50 years. Only securities issued by companies that have increased their total dividend per share amount every year for at least 50 consecutive years are eligible for inclusion in the Index. The Index’s selection universe is composed of all the securities comprising the S&P High Yield Dividend Aristocrats Index. The S&P High Yield Dividend Aristocrats Index measures the performance of companies within the S&P Composite 1500 that have followed a managed-dividends policy of consistently increasing dividends for at least 20 consecutive years.

In selecting securities, the Index first screens out all components of the S&P High Yield Dividend Aristocrats Index that do not meet certain market capitalization, liquidity or dividend growth thresholds. To be eligible for inclusion in the Index, a security must have a market capitalization of at least $2 billion (although current constituents may remain in the Index so long as they maintain a market capitalization of at least $1.5 billion). Additionally, a security must have an average daily value traded greater than or equal to $5 million for the three months prior to the rebalancing reference date (although current constituents may remain in the Index so long as they maintain an average daily value traded greater than or equal to $4.5 million for the three months prior to the rebalancing reference date). Lastly, a security must have increased its total dividend per share amount every year for at least 50 consecutive years.

The Index will select all eligible securities for inclusion, with a minimum constituent count of 25. If fewer than 25 securities are eligible, the Index relaxes the dividend growth eligibility factor as described in the section entitled “Additional Information About the Fund’s Principal Investment Strategy.” Constituents selected for inclusion in the Index are weighted based upon their indicated annual dividend yield, subject to a single constituent weight cap of 5% of the total Index weight. If the Index is ever composed of less than 25 securities, the single constituent weight cap rises to 10% of the total Index weight. Additionally, Index constituents with weights equal to or greater than 5% will not exceed 50% of the total Index weight. In the event this condition is breached, the Index will re-balance pursuant to the mechanism described in the section entitled “Additional Information About the Fund’s Principal Investment Strategy.”

The Index is reconstituted annually and rebalanced quarterly and the Fund will make corresponding changes to its portfolio shortly after the Index changes are made public. The Fund will be concentrated (i.e. hold 25% or more of its total assets) in an industry or a group of industries to the extent that the Index is so concentrated. As of __________, 2023, the Index was concentrated in companies comprising the ________ sector, although this may change from time to time.

The Fund is classified as “non-diversified” under the Investment Company Act of 1940 (the “1940 Act”).

Principal Risks

As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Market Risk. Market risk is the risk that a particular security, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. For example, the coronavirus disease 2019 (COVID-19) global pandemic and the ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. While vaccines have been developed, there is no guarantee that vaccines will be effective against future variants of the disease. As this global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. These events also adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value and the bid/ask spread on Fund Shares may widen.

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

DIVIDEND-PAYING STOCKS RISK. Investing in dividend-paying stocks involves the risk that such stocks may fall out of favor with investors and underperform the broader market. Companies that issue dividend-paying stocks are not required to pay or continue paying dividends on such stocks. It is possible that issuers of the stocks held by the Fund will not declare dividends in the future or will reduce or eliminate the payment of dividends (including reducing or eliminating anticipated accelerations or increases in the payment of dividends) in the future.

Asset Class Risk. Securities and other assets in the Index or in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

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, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. The Index Provider and its agents do not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and do not guarantee that the Index will be calculated in accordance with its stated methodology. The mandate of the Adviser and Sub-Adviser as described in this prospectus is to manage the Fund consistently with the Index provided by the Index Provider. The Adviser and Sub-Adviser rely upon the Index Provider and its agents to accurately compile, maintain, construct, reconstitute, rebalance, compose, calculate and disseminate the Index accurately. Therefore, losses or costs associated with any Index Provider or agent errors generally will be borne by the Fund and its shareholders. To correct any such error, the Index Provider or its agents may carry out an unscheduled rebalance of the Index or other modification of Index constituents or weightings. When the Fund in turn rebalances its portfolio, any transaction costs and market exposure arising from such portfolio rebalancing will be borne by the Fund and its shareholders. Unscheduled rebalances also expose the Fund to additional tracking error risk. Errors in respect of the quality, accuracy and completeness of the data used to compile the Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the Index is less commonly used as a benchmark by funds or advisors. For example, during a period where the Index contains incorrect constituents, the Fund tracking the Index would have market exposure to such constituents and would be underexposed to the Index’s other constituents. Such errors may negatively impact the Fund and its shareholders. The Index Provider and its agents rely on various sources of information to assess the criteria of issuers included in the Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Adviser can offer assurances that the Index’s calculation methodology or sources of information will provide an accurate assessment of included issuers. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Index to vary from its normal or expected composition. The postponement of a scheduled rebalance in a time of market volatility could mean that constituents that would otherwise be removed at rebalance due to changes in market capitalizations, issuer credit ratings, or other reasons may remain, causing the performance and constituents of the Index to vary from those expected under normal conditions. Apart from scheduled rebalances, the Index Provider or its agents may carry out additional ad hoc rebalances to the Index due to unusual market conditions or in order, for example, to correct an error in the selection of Index constituents.

Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline.

ISSUER RISK. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

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

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

New Fund Risk. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Non-Diversification Risk. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

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

Passive Investment Risk. The Fund is not actively managed. The Fund invests in securities included in or representative of the Index regardless of investment merit. The Fund generally will not attempt to take defensive positions in declining markets. Additionally, the Fund’s return may not match the return of the Index for a number of reasons. The Fund incurs operating expenses not applicable to the Index, and may incur costs in buying and selling securities, especially when rebalancing the Fund’s portfolio holdings to reflect changes in the composition of the Index. The Fund’s portfolio holdings may not exactly replicate the securities included in the Index or the ratios between the securities included in the Index. Additionally, although the Fund follows a defined Index rebalance schedule, the Index Provider could determine to suspend or delay a rebalance to a market event, during which time the Fund’s index tracking error may be heightened and could negatively impact investors. Lastly, a stock included in the Index may not exhibit the factor trait or provide specific factor exposure for which it was selected, and consequently, the Fund’s holdings may not exhibit returns consistent with that factor trait.

REIT RISK. REITs typically own and operate income-producing real estate, such as residential or commercial buildings, or real-estate related assets, including mortgages. As a result, investments in REITs are subject to the risks associated with investing in real estate, which may include, but are not limited to: fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local operating expenses; and other economic, political or regulatory occurrences affecting companies in the real estate sector. REITs are also subject to the risk that the real estate market may experience an economic downturn generally, which may have a material effect on the real estate in which the REITs invest and their underlying portfolio securities. REITs may have also a relatively small market capitalization which may result in their shares experiencing less market liquidity and greater price volatility than larger companies.

Structural ETF Risks. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has 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, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

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

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

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

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences, transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest received by the Fund or distributions paid to the Fund’s shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Performance

As of the date of this prospectus, the Fund has not yet commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at https://www.roundhillinvestments.com and will provide some indication of the risks of investing in the Fund.

Management

Investment Adviser: Roundhill Financial Inc.

Investment Sub-Adviser: Exchange Traded Concepts, LLC

Portfolio Managers: The individuals primarily responsible for the day-to-day management of the Fund are Andrew Serowik, Todd Albrecio and Gabriel Tan. Each has served as a portfolio manager since its inception in _________ 2023.

Purchase and Sale of Fund Shares

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

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

Tax Information

The Fund’s distributions are expected to be taxed as ordinary income, qualified dividend income and/or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or individual retirement account. Any withdrawals made from such tax-advantaged arrangement may be taxable to you.

Payments to Broker-Dealers and Other Financial Intermediaries

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

Additional Information About the Fund’s Principal Investment Strategies

Overview

The Fund is a series of Roundhill ETF Trust and is regulated as an “investment company” under the 1940 Act. The Fund operates as an index fund and is not actively managed by the Adviser. As such, the Fund’s investment objective is to track the total return performance, before fees and expenses, of the S&P Dividend Monarchs Index. Each of the policies described herein, including the investment objective of the Fund, constitutes a non-fundamental policy that may be changed by the Board of Trustees of the Trust (the “Board”) without shareholder approval. Certain fundamental policies of the Fund are set forth in the Fund’s Statement of Additional Information (the “SAI”). There can be no assurance that the Fund’s objective will be achieved.

The Fund will generally invest in all the constituents comprising the Index in proportion to their weightings in the Index; however, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index or utilize various combinations of other available investment techniques in seeking to replicate generally the performance of the Index as a whole. This is known as “representative sampling.” Should the Fund utilize a representative sampling strategy, it will invest in a sample of securities that collectively has an investment profile similar to that of the Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (including, but not limited to, return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of the Index. There also may be instances in which the Adviser or Sub-Adviser in seeking to track the Index may choose to (i) overweight a security in the Index, (ii) purchase securities not contained in the Index that the Adviser or Sub-Adviser believes are appropriate to substitute for certain securities in the Index, or (iii) utilize various combinations of other available investment techniques. The Fund may sell securities that are represented in the Index in anticipation of their removal from the Index or purchase securities not represented in the Index in anticipation of their addition to the Index.

The Fund’s investments are subject to certain requirements imposed by law and regulation, as well as the Fund’s investment strategy. These requirements are generally applied at the time the Fund invests its assets. If, subsequent to an investment by the Fund, this requirement is no longer met, the Fund’s future investments will be made in a manner that will bring the Fund into compliance with this requirement.

To the extent that the Index concentrates (i.e., holds 25% or more of its total assets) in the securities of a particular industry or group of industries, the Fund will concentrate its investment to approximately the same extent as the Index.

Additional Information Regarding the Fund’s Principal Investment Strategy

Under normal market conditions, the Fund invests at least 80% of its total assets in the securities comprising the Index. The Fund, using an indexing investment approach, attempts to replicate, before fees and expenses, the performance of the Index. The Index is owned and was developed by SPDJI. The Index Provider reserves the right to make exceptions when applying the methodology if the need arises. In addition, the Index Provider may revise Index policy covering rules for selecting companies, treatment of dividends, share counts or other matters. Roundhill Financial Inc. serves as the Fund’s investment adviser and Exchange Traded Concepts, LLC serves as the Fund’s investment sub-adviser.

In selecting securities, the Index first screens out all components of the S&P High Yield Dividend Aristocrats Index that do not meet certain market capitalization, liquidity or dividend growth thresholds. To be eligible for inclusion in the Index, a security must have a market capitalization of at least $2 billion (although current constituents may remain in the Index so long as they maintain a market capitalization of at least $1.5 billion. Additionally, a security must have an average daily value traded greater than or equal to $5 million for the three months prior to the rebalancing reference date (although current constituents may remain in the Index so long as they maintain an average daily value traded greater than or equal to $4.5 million for the three months prior to the rebalancing reference date). Lastly, a security must have increased its total dividend per share amount every year for at least 50 consecutive years.

The Index will select all eligible securities for inclusion, with a minimum constituent count of 25. If fewer than 25 securities are eligible, the Index relaxes the dividend growth eligibility factor and securities are selected according to the following process: (i) select, in decreasing order of dividend growth history, securities from the selection universe that satisfy the market capitalization and liquidity eligibility factors until the Index contains 25 constituents; (ii) select securities with the same length of dividend growth history in decreasing order of their indicated annual dividend yield.

Constituents selected for inclusion in the Index are weighted based upon their indicated annual dividend yield, subject to a single constituent weight cap of 5% of the total Index weight. If the Index is ever composed of less than 25 securities, the single constituent weight cap rises to 10% of the total Index weight. Additionally, Index constituents with weights equal to or greater than 5% will not exceed 50% of the total Index weight. In the event this condition is breached, the Index will undergo a re-balance pursuant to the following mechanism: securities are ranked in descending order by indicated annual dividend yield. Then cap the security with the lowest indicated annual dividend yield that is greater than 4.5%, at 4.5%, with the excess weight being proportionally redistributed to all companies with weights below 4.5%. Repeat this step iteratively until this condition is satisfied.

Non-Principal Strategies

Borrowing Money. The Fund may borrow money from a bank as permitted by the 1940 Act or the rules thereunder, or by the U.S. Securities and Exchange Commission (“SEC”) or other regulatory agency with authority over the Fund. The 1940 Act presently allows a fund to borrow from any bank (including pledging, mortgaging or hypothecating assets) in an amount up to 33 1/3% of its total assets (not including temporary borrowings not in excess of 5% of its total assets).

Securities Lending. The Fund may lend its portfolio securities. A securities lending program allows the Fund to receive a portion of the income generated by lending its securities and investing the respective collateral. In connection with such loans, the Fund receives liquid collateral equal to at least 102% (105% for non-U.S. securities) of the value of the portfolio securities being lent. This collateral is marked to market on each trading day.

Additional Risks of Investing in the Fund

Risk is inherent in all investing. Investing in the Fund involves risk, including the risk that you may lose all or part of your investment. There can be no assurance that the Fund will meet its stated objective. Before you invest, you should consider the following supplemental disclosure pertaining to the Principal Risks set forth above as well as additional Non-Principal Risks set forth below in this prospectus.

Principal Risks

Structural ETF Risks. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

Non-Principal Risks

Securities Lending Risk. 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.

Management of the Fund

The Fund is a series of Roundhill ETF Trust, an investment company registered under the 1940 Act. The Fund is treated as a separate fund with its own investment objectives and policies.

Management Fee

Pursuant to an investment advisory agreement between Roundhill and the Trust, on behalf of the Fund (the “Investment Management Agreement”), the Fund has agreed to pay an annual unitary management fee to Roundhill in an amount equal to 0.__% of its average daily net assets. This unitary management fee is designed to pay the Fund’s expenses and to compensate Roundhill for the services it provides to the Fund. Out of the unitary management fee, Roundhill pays substantially all expenses of the Fund, including the cost of transfer agency, custody, fund administration, legal, audit and other service and license fees. However, Roundhill is not responsible for distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, acquired fund fees and expenses, taxes, interest, and extraordinary expenses.

Pursuant to an investment sub-advisory agreement between Roundhill, ETC and the Trust, on behalf of the Fund (the “Investment Sub-Advisory Agreement”), Roundhill has agreed to pay an annual sub-advisory fee to ETC in an amount based on the Fund’s average daily net assets. Roundhill is responsible for paying the entirety of ETC’s sub-advisory fee. The Fund does not directly pay ETC.

A discussion regarding the basis for the Board’s approval of the Investment Management Agreement and Investment Sub-Advisory Agreement on behalf of the Fund will be available in the Fund’s next Annual Report to shareholders for the fiscal period ended _____________, 2023.

How to Buy and Sell Shares

Fund Shares are listed for secondary trading on the Exchange and individual Fund Shares may only be purchased and sold in the secondary market through a broker-dealer. The Exchange and secondary markets are closed on weekends and also are generally closed on the following holidays: New Year’s Day, Dr. Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day (observed), Juneteenth, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Exchange may close early on the business day before certain holidays and on the day after Thanksgiving Day. Exchange holiday schedules are subject to change without notice. If you buy or sell Fund Shares in the secondary market, you will pay the secondary market price for Fund Shares. In addition, you may incur customary brokerage commissions and charges and may pay some or all of the spread between the bid and the offered price in the secondary market on each leg of a round trip (purchase and sale) transaction.

The trading prices of Fund Shares will fluctuate continuously throughout trading hours based on market supply and demand rather than the relevant Fund’s net asset value, which is calculated at the end of each business day. Fund Shares will trade on the Exchange at prices that may be above (i.e., at a premium) or below (i.e., at a discount), to varying degrees, the daily net asset value of Fund Shares. The trading prices of Fund Shares may deviate significantly from the Fund’s net asset value during periods of market volatility. Given, however, that Fund Shares can be issued and redeemed daily in Creation Units, the Adviser believes that large discounts and premiums to net asset value should not be sustained over long periods.

Book Entry

Fund Shares are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of, and holds legal title to, all outstanding Fund Shares. Investors owning Fund Shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for Fund Shares.

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

Dividends, Distributions and Taxes

Ordinarily, dividends from net investment income, if any, are declared and paid at least annually by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders annually.

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

Taxes

This section summarizes some of the main U.S. federal income tax consequences of owning shares of the Fund. This section is current as of the date of this prospectus. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a corporation, a non-U.S. person, a broker-dealer, or other investor with special circumstances. In addition, this section does not describe your state, local or non-U.S. tax consequences.

This federal income tax summary is based in part on the advice of counsel to the Fund. The Internal Revenue Service could disagree with any conclusions set forth in this section. In addition, counsel to the Fund may not have been asked to review, and may not have reached a conclusion with respect to, the federal income tax treatment of the assets to be included in the Fund. The following disclosure may not be sufficient for you to use for the purpose of avoiding penalties under federal tax law.

As with any investment, you should seek advice based on your individual circumstances from your own tax advisor.

Fund Status. The Fund intends to qualify as a “regulated investment company” under the federal tax laws. If the Fund qualifies as a regulated investment company and distributes its income as required by the tax law, the Fund generally will not pay federal income taxes.

Distributions. The Fund’s distributions are generally taxable. After the end of each year, you will receive a tax statement that separates the distributions of the Fund into two categories, ordinary income distributions and capital gain dividends. Ordinary income distributions are generally taxed at your ordinary tax rate, however, as further discussed below, certain ordinary income distributions received from the Fund may be taxed at the capital gains tax rates. Generally, you will treat all capital gain dividends as long-term capital gains regardless of how long you have owned your shares.

To determine your actual tax liability for your capital gain dividends, you must calculate your total net capital gain or loss for the tax year after considering all of your other taxable transactions, as described below. In addition, the Fund may make distributions that represent a return of capital for tax purposes and thus will generally not be taxable to you; however, such distributions may reduce your tax basis in your Fund Shares, which could result in you having to pay higher taxes in the future when Fund Shares are sold, even if you sell the Fund Shares at a loss from your original investment. A “return of capital” is a return, in whole or in part, of the funds that you previously invested in the Fund. A return of capital distribution should not be considered part of the Fund’s dividend yield or total return of an investment in Fund Shares. The tax status of your distributions from the Fund is not affected by whether you reinvest your distributions in additional Fund Shares or receive them in cash. The income from the Fund that you must take into account for federal income tax purposes is not reduced by amounts used to pay a deferred sales fee, if any. The tax laws may require you to treat distributions made to you in January as if you had received them on December 31 of the previous year.

Income from the Fund may also be subject to a 3.8% “Medicare tax.” This tax generally applies to your net investment income if your adjusted gross income exceeds certain threshold amounts, which are $250,000 in the case of married couples filing joint returns and $200,000 in the case of single individuals. Interest that is excluded from gross income and exempt-interest dividends from the Fund are generally not included in your net investment income for purposes of this tax.

Dividends Received Deduction. A corporation that owns Fund Shares generally will not be entitled to the dividends received deduction with respect to many dividends received from the Fund because the dividends received deduction is generally not available for distributions from regulated investment companies. However, certain ordinary income dividends on Fund Shares that are attributable to qualifying dividends received by the Fund from certain corporations may be reported by the Fund as being eligible for the dividends received deduction.

Capital Gains and Losses and Certain Ordinary Income Dividends. If you are an individual, the maximum marginal stated federal tax rate for net capital gain is generally 20% (15% or 0% for taxpayers with taxable income below certain thresholds). Some capital gains, including some portion of your capital gain dividends may be taxed at a higher maximum stated tax rate. Capital gains may also be subject to the Medicare tax described above.

Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your shares to determine your holding period. However, if you receive a capital gain dividend from the Fund and sell your share at a loss after holding it for six months or less, the loss will be recharacterized as long-term capital loss to the extent of the capital gain dividend received. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Internal Revenue Code of 1986, as amended, treats certain capital gains as ordinary income in special situations.

An election may be available to you to defer recognition of the gain attributable to a capital gain dividend if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Ordinary income dividends received by an individual shareholder from regulated investment companies such as the Fund are generally taxed at the same rates that apply to net capital gain (as discussed above), provided certain holding period requirements are satisfied and provided the dividends are attributable to qualifying dividends received by the Fund itself. The Fund provides notice to its shareholders of the amount of any distribution which may be taken into account as a dividend which is eligible for the capital gains tax rates.

Sale of Fund Shares. If you sell or redeem your Fund Shares, you will generally recognize a taxable gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in your Fund Shares from the amount you receive in the transaction. Your tax basis in your Fund Shares is generally equal to the cost of your Fund Shares, generally including sales charges. In some cases, however, you may have to adjust your tax basis after you purchase your Fund Shares. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Taxes on Purchase and Redemption of Creation Units. If you exchange securities for Creation Units, you will generally recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and your aggregate basis in the securities surrendered and the cash component paid. If you exchange Creation Units for securities, you will generally recognize a gain or loss equal to the difference between your basis in the Creation Units and the aggregate market value of the securities received and the cash redemption amount. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units or Creation Units for securities cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position.

Treatment of Expenses. Expenses incurred and deducted by the Fund will generally not be treated as income taxable to you.

Non-U.S. Tax Credit. Because the Fund may invest in non-U.S. securities, the tax statement that you receive may include an item showing non-U.S. taxes the Fund paid to other countries. In this case, dividends taxed to you will include your share of the taxes the Fund paid to other countries. You may be able to deduct or receive a tax credit for your share of these taxes.

Non-U.S. Investors. If you are a non-U.S. investor (i.e., an investor other than a U.S. citizen or resident or a U.S. corporation, partnership, estate or trust), you should be aware that, generally, subject to applicable tax treaties, distributions from the Fund are characterized as dividends for federal income tax purposes (other than dividends which the Fund properly reports as capital gain dividends) are subject to U.S. federal income taxes, including withholding taxes, subject to certain exceptions described below. However, distributions received by a non-U.S. investor from the Fund that are properly reported by the Fund as capital gain dividends may not be subject to U.S. federal income taxes, including withholding taxes, provided that the Fund makes certain elections and certain other conditions are met. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as short-term capital gain income dividend attributable to certain net short term capital gain received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. investors, provided that the Fund makes certain elections and certain other conditions are met. For tax years after December 31, 2022, amounts paid to or recognized by a non-U.S. affiliate that are excluded from tax under the portfolio interest, capital gain dividends, short-term capital gains or tax-exempt interest dividend exceptions or applicable treaties, may be taken into consideration in determining whether a corporation is an “applicable corporation” subject to a 15% minimum tax on adjusted financial statement income.

Distributions may be subject to a U.S. withholding tax of 30% in the case of distributions to (i) certain non-U.S. financial institutions that have not entered into an agreement with the U.S. Treasury to collect and disclose certain information and are not resident in a jurisdiction that has entered into such an agreement with the U.S. Treasury and (ii) certain other non-U.S. entities that do not provide certain certifications and information about the entity’s U.S. owners. This withholding tax is also currently scheduled to apply to the gross proceeds from the disposition of securities that produce U.S. source interest or dividends. However, proposed regulations may eliminate the requirement to withhold on payments of gross proceeds from dispositions.

It is the responsibility of the entity through which you hold your Fund Shares to determine the applicable withholding.

Investments in Certain Non-U.S. Corporations. If the Fund holds an equity interest in any “passive foreign investment companies” (“PFICs”), which are generally certain non-U.S. corporations that receive at least 75% of their annual gross income from passive sources (such as interest, dividends, certain rents and royalties or capital gains) or that hold at least 50% of their assets in investments producing such passive income, the Fund could be subject to U.S. federal income tax and additional interest charges on gains and certain distributions with respect to those equity interests, even if all the income or gain is timely distributed to its shareholders. The Fund will not be able to pass through to its shareholders any credit or deduction for such taxes. The Fund may be able to make an election that could ameliorate these adverse tax consequences. In this case, the Fund would recognize as ordinary income any increase in the value of such PFIC shares, and as ordinary loss any decrease in such value to the extent it did not exceed prior increases included in income. Under this election, the Fund might be required to recognize in a year income in excess of its distributions from PFICs and its proceeds from dispositions of PFIC stock during that year, and such income would nevertheless be subject to the distribution requirement and would be taken into account for purposes of the 4% excise tax. Dividends paid by PFICs are not treated as qualified dividend income.

The foregoing discussion summarizes some of the possible consequences under current federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You also may be subject to state and local taxes on Fund distributions and sales of Fund Shares.

Distributor

Foreside Fund Services, LLC serves as the distributor of Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in Fund Shares.

Net Asset Value

The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the close of regular trading hours of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding Fund Shares, generally rounded to the nearest cent.

The Board has adopted valuation policies and procedures pursuant to which it has designated the Adviser to determine the fair value of the Fund’s investments, subject to the Board’s oversight, when market prices for those investments are not “readily available,” including when they are determined by the Adviser to be unreliable. Such circumstances may arise when: (i) a security has been de-listed or its trading halted or suspended; (ii) a security’s primary pricing source is unable or unwilling to provide a price; (iii) a security’s primary trading market is closed during regular market hours; or (iv) a security’s value has been materially affected by events occurring after the close of the security’s primary trading market and before a Fund calculates its NAV. Generally, when determining the fair value of a Fund investment, the Adviser will take into account all reasonably available information that may be relevant to a particular valuation including, but not limited to, fundamental analytical data regarding the issuer, information relating to the issuer’s business, recent trades or offers of the security, general and/or specific market conditions and the specific facts giving rise to the need to fair value the security. Fair value determinations are made in good faith and in accordance with the fair value methodologies established by the Adviser. Due to the subjective and variable nature of determining the fair value of a security or other investment, there can be no assurance that the Adviser’s determined fair value will match or closely correlate to any market quotation that subsequently becomes available or the price quoted or published by other sources. In addition, the Fund may not be able to obtain the fair value assigned to an investment if the Fund were to sell such investment at or near the time its fair value is determined.

Fund Service Providers

U.S. Bancorp Fund Services, LLC is the administrator and transfer agent for the Trust. U.S. Bank National Association serves as the custodian for the Trust.

Chapman and Cutler LLP, 320 South Canal Street, Chicago, Illinois 60606, serves as legal counsel to the Trust.

Cohen & Company, 342 North Water Street, Suite 830, Milwaukee, Wisconsin 53202, serves as the Fund’s independent registered public accounting firm and is responsible for auditing the annual financial statements of the Fund.

Premium/Discount Information

Information showing the number of days the market price of the Fund Shares was greater (at a premium) and less (at a discount) than the Fund’s NAV for the most recently completed calendar year, and the most recently completed calendar quarters since that year (or the life of the Fund, if shorter), is available at www._________________.com.

Investments by Other Investment Companies

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies, including Fund Shares. The SEC has adopted Rule 12d1-4 under the 1940 Act The Fund is required to comply with the conditions of Rule 12d1-4, which allows, subject to certain conditions, the Fund to invest in other registered investment companies and other registered investment companies to invest in the Fund beyond the limits contained in Section 12(d)(1) of the 1940 Act.
