ESK – REX-Osprey™ ETH + Staking ETF offers exposure to spot Ethereum and delivers monthly staking rewards — building on the firm’s suite of crypto-staking ETFs

REX-Osprey™, a strategic collaboration between REX Shares and Osprey Funds, today announced the launch of ESK, the REX-Osprey™ ETH + Staking ETF, the first 1940 Act U.S.-listed ETF to give investors exposure to Ethereum (ETH) plus staking rewards.

ESK is the first US fund to provide investors with cost-effective and convenient exposure to spot Ethereum (ETH) via the 1940 Act ETF structure. It also delivers the benefits of ETH staking, which allows investors to participate in Ethereum’s proof-of-stake network by receiving monthly distributions. The Fund seeks its investment objective by holding a combination of directly staked ETH and other exchange-traded products that themselves hold and stake spot ETH. Importantly, all staking rewards received by the fund are passed directly to investors, with neither REX nor Osprey retaining any portion.

An investment in the Fund is not a direct investment in Ethereum. Investing involves significant risk, including the loss of principal.

“With ESK, we’re giving investors access to Ethereum plus staking rewards in the most broad-based US ETF format,” said Greg King, CEO of REX Financial. “This continues our work of introducing crypto staking through the ETF structure.”

The launch follows the successful debut of SSK, the REX-Osprey™ Solana + Staking ETF, on July 2, 2025. SSK was the first Solana ETF to offer exposure to spot Solana returns in the U.S. and the first Cryptocurrency ETF of any kind in the US to provide distributions related to staking rewards. Since launch, SSK has surpassed $300 million in assets under management and, as of September 1, converted to a Regulated Investment Company (RIC) structure, enhancing tax efficiency for investors while maintaining its distinct spot exposure + staking strategy.

Investing in the Fund involves a high degree of risk. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund.

An investor should carefully consider the Fund’s investment objective, risks, charges, and expenses before investing. The Fund’s prospectus and summary prospectus contain this and other information about the REX Shares. To obtain the Fund’s prospectus and summary prospectus, call 1-844-802-4004. The Fund’s prospectus and summary prospectus should be read carefully before investing.

THE FUND, TRUST AND ADVISER ARE NOT AFFILIATED WITH ETHEREUM OR ANY ENTITY PROVIDING VALIDATION OR STAKING SERVICES.

The Fund’s investment exposure is concentrated in the Ethereum ecosystem. Risks associated with this exposure may adversely affect the Fund’s net asset value (“NAV”) per share, trading price, yield, total return, and/or ability to meet its investment objective.

The value of the Fund, which focuses on underlying securities in the crypto sector, may be more volatile than a more diversified pooled investment or the market as a whole and may perform differently from the value of a more diversified pooled investment or the market as a whole.

Crypto Asset Risk. The Fund holds ETH tokens, a crypto asset that is native to the Ethereum blockchain. Crypto assets are subject to extreme volatility, regulatory uncertainty, market manipulation, security risks, and technological changes. The value of the Fund will fluctuate with the price of ETH, which is influenced by a range of factors including adoption of the Ethereum network, network congestion, smart contract failures, validator misbehavior, and the emergence of competing platforms. Additionally, crypto asset exchanges and counterparties may be less regulated than traditional financial institutions, and are subject to fraud, hacking, and operational disruptions.

Ethereum (“ETH” or the “Reference Asset) Investing Risk. ETH is a relatively new innovation and is subject to unique and substantial risks. The market for ETH is subject to rapid price swings, changes and uncertainty. A significant portion of the demand for ETH may be the result of speculation. Such speculation regarding the potential future appreciation of the price of ETH may artificially inflate or deflate the price of ETH and increase volatility. The further development of the Ethereum Network and the acceptance and use of ETH are subject to a variety of factors that are difficult to evaluate. The slowing, stopping or reversing of the development of the Ethereum Network or the acceptance of ETH may adversely affect the price and liquidity of ETH. ETH is subject to the risk of fraud, theft, manipulation or security failures, operational or other problems that impact ETH trading platforms. Additionally, if a coordinated group of validators were to gain control of more than 50% of staked ether, they would have the ability to execute extensive attacks, manipulate transactions and fraudulently obtain ether. If such a validator or group of validators were to gain control of one-third of staked ether, they could halt payments. A significant portion of ETH is held by a small number of holders sometimes referred to as “whales”. Transactions by these holders may influence the price of ether.

Staking Risk. When the Fund stakes the Reference Asset, the Reference Asset is subject to the risks attendant to staking generally. Staking requires that the Fund lock up the staked Reference Asset for the period of time required by the staking protocol, meaning that the Fund cannot sell or transfer the staked Reference Asset, thereby making it illiquid for the period it is being staked. In addition, during the lock-up period, the Fund is subject to the market price volatility of the Reference Asset, and it may miss opportunities to sell the staked Reference Asset during opportune times. During the unstaking period, the Fund may miss out on earning opportunities because, in some cases, the staked Reference Asset may not earn rewards during the unstaking period or may only earn rewards during part of the unstaking period. Staked Reference Assets are also subject to security breaches, network downtime or attacks, smart contract vulnerabilities, and validator or custodian failure or compromise, which can result in a complete loss of the staked Reference Asset or a loss of any rewards.

Concentration Risk. The Fund’s assets will be concentrated in the sector or sectors or industry or group of industries that are assigned to the Reference Asset, which will subject the Fund to the risk that economic, political or other conditions that have a negative effect on those sectors and/or industries may negatively impact the Fund to a greater extent than if the Fund’s assets were invested in a wider variety of sectors or industries.

Liquidity Risk. The Fund may not be able to sell its crypto assets at the time or price it desires. Crypto asset markets may be less liquid than traditional securities markets and may be subject to significant price fluctuations.

New Fund Risk. The Fund is a newly organized investment company with no operating history. Investors have limited performance history to assess how the Fund will perform.

Non-Diversification Risk. The Fund is non-diversified, which means it may invest a greater percentage of its assets in a smaller number of issuers than a diversified fund. This may increase the volatility of the Fund’s NAV and may lead to greater losses during periods of market declines.

Indirect Investment Risk. Neither the Reference Asset nor the Ethereum Network are affiliated with the Trust, the Fund, or the Adviser, or any affiliates thereof and are not involved with this offering in any way, and have no obligation to consider the Fund in taking any actions that might affect the value of the Fund. None of the Trust, the Fund, the Adviser, or any affiliate are responsible for the performance of the Reference Asset and make no representation as to the performance of the Reference Asset. Investing in the Fund is not equivalent to investing in the Reference Asset.

Regulatory Risk. The Fund’s investments in crypto assets may be subject to varying laws and regulations across jurisdictions, including tax laws and regulations. These laws and regulations may change without warning, and enforcement actions may be taken, which could have an adverse effect on the Fund and its operations.

Custody Risk. The Reference Asset and other assets held by the Fund that operate on distributed ledger/blockchain technology can only be transferred by the person holding both the public and private keys to the digital wallet in which the asset is held. The Fund’s custodians that custody the Fund’s digital assets are on control of the private keys for each of the Fund’s digital wallets. In the event such custodian loses sole control of the private keys (e.g., through a data breach or hack), the Fund’s digital assets held by such custodian could be lost.

Digital Assets Risk. The performance of the Reference Asset, and consequently the Fund’s performance, is subject to the risks of the digital assets industry. The trading prices of many digital assets, including the Reference Asset, have experienced extreme volatility in recent periods and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of the Reference Asset, could have a material adverse effect on the value of the Shares (defined below) and the Shares could lose all or substantially all of their value. The value of the Shares is subject to a number of factors relating to the fundamental investment characteristics of the Reference Asset as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies. Digital assets represent a new and rapidly evolving industry, and the value of the Shares depends on the acceptance of the Reference Asset. Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network’s ability to grow and respond to challenges.

Foreign Securities Risk. To the extent the Fund invests in foreign securities, they may be subject to additional risks not typically associated with investments in domestic securities.

Counterparty Risk. The Fund may rely on staking infrastructure providers, custodians, and crypto exchanges to hold or interact with its ETH. These third parties may become insolvent, fail to safeguard assets, or be subject to regulatory action, leading to potential losses.

Smart Contract Risk. Certain staking activities or custodial processes may rely on smart contracts. These self-executing code structures are susceptible to bugs, hacking, or unintended behavior. Exploits in smart contracts could cause loss of assets or incorrect reward distribution.

Market Risk. The value of the Fund’s investments may decline due to market movements, economic conditions, or other factors affecting the overall crypto asset market or Ethereum Network.

Tax Risk. The Fund intends to qualify and remain qualified as a RIC under the Code. Each Fund will qualify as a RIC if, among other things, it meets the source-of-income and the asset-diversification requirements. Failing to qualify as a RIC for tax purposes could have adverse consequences for the Fund and its shareholders. These issues are described in more detail in the section entitled “ADDITIONAL INFORMATION ABOUT RISK – Tax Risk” below, as well as in the Fund’s SAI.
