The Fund is an actively managed exchange traded fund (“ETF”) that attempts to achieve two times (200%) the daily percentage change in the share price of the Underlying Security by employing derivatives, namely swap agreements and/or listed options contracts. The Fund aims to achieve this daily percentage change for a single day, and not for any other period. A “single day” means the period “from the close of regular trading on one trading day to the close on the next trading day.”

If the Fund encounters limitations in implementing its strategies, whether due to market conditions, derivative availability, counterparty issues, or other factors, the Fund may not achieve investment results, before fees and expenses, that correspond to two times (2x) the daily performance of the Underlying Security, and may return substantially less during such periods. During such periods, the Fund’s actual leverage levels may differ substantially from its intended target, both intraday and at the close of trading, potentially resulting in significantly lower returns.

The Fund may enter into one or more swap agreements with financial institutions for a specified period, which may range from one day to longer than a year. Through each swap agreement, the Fund and the financial institution will agree to exchange the return (or differentials in rates of return) earned or realized on the Underlying Security’s share price. The gross return (meaning the return before deducting any fees or expenses) to be exchanged or “swapped” between the parties is calculated with respect to a “notional amount,” (meaning the face amount of the instrument) e.g., the return on or change in value of a particular dollar amount representing the Underlying Security.

The Fund may also utilize listed options to seek to achieve leveraged 2X exposure to the Underlying Security. The Fund will primarily employ short-dated (a month or less) in-the-money call options (options with strike prices below the current market price of the Underlying Security, offering immediate intrinsic value). Additionally, the Fund may use other option strategies to produce similar exposure to the Underlying Security, like buying calls and selling puts with identical strike prices. These options allow the Fund to adjust its leverage strategy in response to market conditions, liquidity constraints, or other factors that may affect the availability or pricing of swap agreements. The use of listed options provides additional flexibility in pursuing the Fund’s daily investment objective. In situations where swap availability is constrained, the Fund may rely more heavily on options contracts. Additionally, the Fund may use options in response to changing market dynamics. However, the use of option contracts is typically less efficient than swaps and may increase the likelihood that the Fund is unable to achieve its daily 2X objective.

At the end of each day, the Fund’s swaps and options are valued using market valuations and the Fund’s investment adviser rebalances the Fund’s holdings in an attempt to maintain leveraged exposure for the Fund equal to approximately 200% of the Underlying Security’s share price. This daily rebalancing is expected to result in high portfolio turnover.

For examples of a hypothetical investment in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Fund – Principal Investment Strategies.”

Fund performance for periods greater than one single day is primarily (but not solely) a function of the following factors: a) the Underlying Security volatility; b) the Underlying Security’s performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses.

The Fund will hold assets to serve as collateral for its derivatives positions. For those collateral holdings, 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; (3) short term bond ETFs; and/or (4) corporate debt securities, such as commercial paper and other short-term unsecured promissory notes issued by businesses that are rated investment grade or of comparable quality.

The Fund has adopted a policy to have at least 80% exposure to financial instruments with economic characteristics that should perform 2X the daily performance of the Underlying Security’s shares. The Fund is expected to allocate between 40% and 60% of its assets as collateral for swap agreements or as premiums for purchased options contracts.

Due to the Fund’s investment strategy, the Fund’s investment exposure is concentrated (i.e., holds 25% or more of its total assets) in the same industry or group of industries in which Underlying Security concentrates. In turn, the Underlying Security concentrates its investments in a particular industry or group of industries to approximately the same extent that its index is concentrated. As of April 30, 2026, the Underlying Security’s index was concentrated in the metals and mining industry and had significant exposure to the materials sector.

The Fund is classified as “non-diversified” under the 1940 Act.

Because of daily rebalancing and the compounding of each day’s return over time, the return of the Fund for periods longer than a single day will be the result of each day’s returns compounded over the period, which will very likely differ from 200% of the return of the Underlying Security’s shares over the same period. The Fund will lose money if the Underlying Security’s performance is flat over time, and because of daily rebalancing, the Underlying Security’s shares’ volatility and the effects of compounding, the Fund may lose money over time while the Underlying Security’s performance increases over a period longer than a single day. As a consequence, investors should not plan to hold shares of the Fund unmonitored for periods longer than a single trading day.
