COIW — Roundhill COIN WeeklyPay ETF

The Fund is actively managed and seeks to achieve its investment objectives by investing in total return swap agreements and common stock that in aggregate return approximately 1.2 times (120%) the calendar week total return of common shares of COIN while making weekly distribution payments to shareholders. The Fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in swaps that utilize COIN as the reference asset and in shares of COIN. For purposes of compliance with this investment policy, derivative contracts will be valued at their notional value.

There is no guarantee that the Fund will successfully provide returns that correspond to approximately 1.2 times (120%) the calendar week total return of common shares of COIN. The implication of an investment strategy that seeks to provide a weekly return that is approximately 1.2 times (120%) the calendar week total return of common shares of COIN is that if COIN experiences an increase in value over a given calendar week, the Fund could be expected to experience a gain approximately 20% larger than the gain experienced by COIN.

Conversely, if COIN experiences a decrease in value over a given calendar week, the Fund could be expected to experience a loss approximately 20% larger than the loss experienced by COIN. On the close of the last business day every calendar week, the Fund’s exposure will be reset to approximately 1.2 times (120%). There set of the leverage factor may result in either a decrease or increase in notional exposure, depending on the performance of COIN over the course of a given week. Therefore, the Fund will provide exposure to the weekly total return of COIN shares.

Accordingly, the Fund is not an appropriate investment for investors seeking exposure to the daily total return of COIN shares. A“calendar week” is measured from the close of trading on the final day of the week that the New York Stock Exchange (“NYSE”)is open for trading on one week to the close of trading on the final day of the subsequent week that the NYSE is open for trading.

For example, if Thursday is the last day of the week that the NYSE is open for trading in a given week, and Friday is the last day of the subsequent week that the NYSE is open for trading, the Fund will provide exposure to the performance of COIN shares from the close of trading on Thursday until the close of trading on the following Friday. In addition to providing 1.2 times (120%) exposure to the total return of COIN shares over a given calendar week, the Fund will make weekly distribution payments to shareholders.

The amount of each week’s distribution is based upon a formula that incorporates a number of dynamic market-based inputs, including the recent total return of COIN shares and the implied volatility of COIN shares. Accordingly, the Fund’sweekly distribution should be expected to change from week to week. The Adviser intends for a significant portion of the Fund’sweekly distributions to be characterized as return of capital, though it can make no assurances this will be the case.

Return of capital represents a return of a portion of a Fund shareholder’s invested capital and is not taxable in the year it is received unless the distribution exceeds a shareholder’s basis in the Fund. However, a return of capital may result in an increase in a later gain ona sale of Fund Shares or a reduction of a loss. The Fund seeks to achieve its investment objectives without regard to overall market movement or the increase or decrease in the value of COIN shares. Accordingly, the Fund will not take defensive positions.

In addition to the swap agreements and shares of COIN, the Fund will also invest significantly in short-term U.S. Treasury securities, short-term U.S. Treasury ETFs, and money market funds that will be used tocollateralize such agreements. As a result of its investment strategies,the Fund will be concentrated in the industry or group of industries to which COIN is assigned (i.e., hold 25% or more of its total assets in investments that provide exposure to the industry or group of industries to which COIN is assigned).

As of March 31, 2026, COIN is assigned to the “financial services” industry group of the financial sector. The Fund is classified as “non-diversified”under the Investment Company Act of 1940 (the “1940 Act”). It is critical that investors understand the following: 1.An investment in the Fund is not an investment in COIN. 2.The Fund’s strategy is subject to all potential losses if COIN shares decrease in value, and may lose all of its value if shares of COIN decrease by 83.33 percent over the course of any calendar week.
