ESK Objective:
REX-Osprey™ ETH + Staking ETF (the “Fund”) seeks investment results of 1x the performance, before fees and expenses, of Ether (“ETH” or the “Reference Asset”) plus staking rewards associated with the Reference Asset.
Investing in ESK is not equivalent to investing directly in Ethereum.
ESK Materials:
Median 30 Day Spread is a calculation of Fund’s median bid-ask spread, expressed as a percentage rounded to the nearest hundredth, computed by: identifying the Fund’s national best bid and national best offer as of the end of each 10 second interval during each trading day of the last 30 calendar days; dividing the difference between each such bid and offer by the midpoint of the national best bid and national best offer; and identifying the median of those values.
FAQ
ESK – The REX-Osprey™ ETH + Staking ETF is the first-ever U.S.-listed ETF offering native staking rewards on Ethereum (ETH). It provides direct price exposure to ETH along with blockchain-based staking income—all delivered through the simplicity of an ETF structure.
ESK participates in the Ethereum network’s proof-of-stake validation process. Staking rewards are paid out to investors in monthly cash distributions, eliminating the need for delegation and restaking. Investors receive distributions of staking rewards without managing any of the infrastructure.
ESK is designed for a range of investors:
- Retail investors seeking crypto exposure through a brokerage account
- Crypto-native investors who want to support the bridge between blockchain innovation and mainstream adoption
- Financial advisors and RIAs looking for spot Ethereum access
- Institutions that require ETF transparency
Yes. Staking rewards are paid in-kind to the fund and increase its NAV, which may result in taxable income to shareholders. Depending on the fund’s earnings and distributions, this income may be treated as ordinary income, capital gains, or return of capital. Investors should consult their tax advisor for guidance.
Yes. ESK is actively managed to optimize validator performance and staking execution. The manager selects and monitors validator partners to maximize uptime and reward efficiency, while maintaining compliance with the Investment Company Act of 1940.
- First U.S. ETF offering native staking rewards on Ethereum
- Uses real on-chain staking, not synthetic yield or derivatives
- Provides digital wallet custody
- Offers daily liquidity, transparent NAV tracking, and ETF-level oversight
ESK Holdings:
The Fund, under normal market conditions, invests at least 80% of its net assets (plus any borrowings for investment purposes) in the Reference Asset and other assets that provide exposure to the Reference Asset. The Fund will invest directly or through the REX-Osprey™ ETH Subsidiary, which is described more fully in the prospectus. Although the Fund seeks returns that correspond to the returns of the Reference Asset, the Fund’s performance will not replicate the performance of the Reference Asset.

Fund holdings are subject to change.
ESK Distribution:
*The Distribution Rate is the annual rate an investor would receive if the most recently declared distribution, from staking rewards, remained the same going forward. The Distribution Rate is calculated by multiplying an ETF’s Distribution per Share by twelve (12), and dividing the resulting amount by the ETF’s most recent NAV. The Distribution Rate represents a single distribution from the ETF and does not represent its total return. Current distributions consist of 100% estimated return of capital (ROC). For full details on the composition of distributions, please refer to the latest 19a-1 notice. **The 30-Day SEC Yield represents net investment income, which excludes option income, earned by such ETF over the 30-Day period, expressed as an annual percentage rate based on such ETF’s share price at the end of the 30-Day period. The REX-Osprey™ ETH + Staking ETF has a gross expense ratio of 0.75%. Distributions are not guaranteed.
The Distribution Rate and 30-Day SEC Yield is not indicative of future distributions, if any, on the ETFs. In particular, future distributions on any ETF may differ significantly from its Distribution Rate or 30-Day SEC Yield. You are not guaranteed a distribution under the ETFs. Distributions for the ETFs (if any) are variable and may vary significantly from month to month and may be zero. Accordingly, the Distribution Rate and 30-Day SEC Yield will change over time, and such change may be significant. The distribution may include a combination of ordinary dividends, capital gain, and return of investor capital, which may decrease a fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment. These distribution rates caused by unusually favorable market conditions may not be sustainable. Such conditions may not continue to exist and there should be no expectation that this performance may be repeated in the future. Additional fund risks can be found below.

ESK Performance:
The performance data quoted represents past performance. Past performance does not guarantee future results. The investment return and principal value of an investment will fluctuate so that an investor’s shares, when sold or redeemed, may be worth more or less than their original cost and current performance may be lower or higher than the performance quoted. Performance current to the most recent month-end can be obtained by calling 1-844-802-4004. Short term performance, in particular, is not a good indication of the fund’s future performance, and an investment should not be made based solely on returns.
Market Price: The current price at which shares are bought and sold. Market returns are based upon the last trade price.
NAV: The dollar value of a single share, based on the value of the underlying assets of the fund minus its liabilities, divided by the number of shares outstanding. Calculated at the end of each business day.
