21Shares Ethereum ETF

You should carefully consider the risk factors discussed below as well as the risk factors discussed in “Risk Factors” in our Annual Report, which could materially affect our business, financial condition or future results. Other than as described herein, there have been no material changes in our risk factors from those disclosed in our Annual Report.

The risks described below, in our Annual Report and subsequent Quarterly Reports, are not the only risks facing the Trust. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Effective October 8, 2025, the Trust allows for staking. Certain of the Trust’s risk factors, as set forth below, have been updated to reflect this change.

In September 2022, the Ethereum network moved from a proof-of-work to a proof-of-stake mechanism called Serenity, or Ethereum 2.0. Unlike proof-of-work, in which miners expend computational resources to compete to validate transactions and are rewarded coins in proportion to the amount of computational resources expended, in proof-of-stake, validators risk or “stake” coins to compete to be randomly selected to validate transactions and are rewarded coins in proportion to the total amount of coins staked. Any malicious activity, such as disagreeing with the eventual consensus or otherwise violating protocol rules, results in the forfeiture or “slashing” of a portion of the staked coins. To the extent the Sponsor determines to stake a portion of the Trust’s ether, the Sponsor plans to engage one or more third party staking services providers (each a “Staking Services Provider”) to conduct such staking activities (“Staking Activities”).Should any of the Trust’s Staking Services Providers engage in malicious activity or perform poorly, then such Staking Services Providers may be blacklisted which could negatively impact the Trust’s abilities to engage in Staking Activities and/or otherwise result in the Trust earning reduced staking rewards. Proof-of-stake is viewed as more energy efficient and scalable than proof-of-work. There is no guarantee that the Ethereum community will embrace Ethereum 2.0, and the new protocol may never fully scale.

Staking introduces a risk of loss of ether. None of the Trust’s assets, including potentially staked assets, are subject to the protections enjoyed by depositors or customers of institutions with FDIC or Securities Investor Protection Corporation membership. The Ethereum network imposes three types of sanctions for validator misbehavior or inactivity, which would result in a portion of staked ether being destroyed or “burned”: penalties, slashing and inactivity leaks.

There can be no guarantee that penalties, slashing or inactivity leaks and resulting losses will not occur as a result of the Staking Activities, if they are undertaken. Furthermore, a staking provider’s liability to the Trust is limited, and a staking provider may lack the assets or insurance in order to support the recovery of any losses incurred. There can be no guarantee that the Trust would recover any of its staked assets, or the value thereof, if it is subject to sanctions imposed by the Ethereum network.

The Sponsor may, from time to time, stake a portion of the Trust’s ether on behalf of the Trust through one or more Staking Services Providers. Under current Ethereum network protocols, staked ether tokens are permitted to be un-staked by the holder of such ether tokens. However, as part of the “activating” and “exiting” processes of staking, staked ether tokens will be inaccessible for a variable period of time determined by a range of factors, including network congestion, resulting in certain liquidity risks that the Sponsor plans to manage.

“Activation” is the funding of a validator to be included in the active set, thereby allowing the validator to participate in the Ethereum network’s proof-of-stake consensus protocol. “Exit” is the request to exit from the active set and no longer participate in the Ethereum network’s proof-of-stake consensus protocol. As part of these “activating” and “exiting” processes of staking on the Ethereum network, any staked ether will be inaccessible for a period of time. The duration of activating and exiting periods are dependent on a range of factors, including network conditions. However, depending on demand, un-staking can take between hours, days or weeks to complete. This can result in certain liquidity risk to the Trust, which the Sponsor will seek to manage through a range of risk management methods.

Even in the event the Trust is then permitted to operate an ongoing redemption program due to the time involved in “exiting” the staking process there is a risk that the Trust could become unable to timely meet excessive redemption requests in amounts that are greater than the portion of the Trust’s ether that remains un-staked, leading to temporary delays in settlement and, in extreme scenarios, the temporary unavailability of the Trust’s redemption program. Moreover, any staked ether which must be un-staked in order to fulfill a redemption (to the extent such redemption cannot be fulfilled utilizing the portion of the Trust’s ether that has not been staked) will be un-staked only after the redemption request is approved by the Trust, the Sponsor executes an un-stake or withdrawal transaction, and such transaction is processed by the Ethereum network. The Staking Services Provider will not be able to change the addresses on the Ethereum network to which staked ether is to be withdrawn or to which ether rewards shall be sent.

The amount of staking rewards that the Trust’s staking activity will generate will be dependent on the performance of the Staking Services Providers, including the adequacy and reliability of the hardware and software utilized by the Staking Services Providers. If the Staking Services Providers experience service outages or otherwise are unable to optimally execute the staking of the Trust’s ether, the Trust’s staking rewards may be adversely affected.

The Trust will not stake its ether until it has determined that the Sponsor in its sole discretion determines that the Trust may do so without undue legal or regulatory risk, such as, without limitation, the risk of jeopardizing the Trust’s ability to qualify as a grantor trust for tax purposes, which could harm the value of the Shares.

The Trust’s investment objective is to seek to track the performance of ether, as measured by the performance of the Index adjusted for the Trust’s expenses and other liabilities, and to reflect rewards from staking a portion of the Trust’s ether, to the extent the Sponsor in its sole discretion determines that the Trust may do so without undue legal or regulatory risk, such as, without limitation, the risk of jeopardizing the Trust’s ability to qualify as a grantor trust for tax purposes. If the Sponsor determines the Trust is not able to so carry out staking activities, the Trust may cease some or all of its staking activities. Staking on the Ethereum network involves delegating ether to validators and carries risks discussed further below. Staked ether may be subject to community-determined penalties for validator misbehavior, or slashing. If the Staking Provider causes the Trust’s staked ether to be subject to such slashing losses, the Trust could suffer losses of the staked ether. Additionally, the staking process includes protocol-defined warm-up, activation and withdrawal periods, during which staked ether is temporarily locked and inaccessible. These phases affect when ether begins earning rewards, participates in consensus and becomes available for transfer or redelegation.

The Staking Provider will stake the Trust’s ether as the node operator and will operate a validator node to stake the Trust’s ether. The Staking Provider will perform its staking services in collaboration with the Custodians, as the ether will be staked directly from the Trust’s ether accounts with the Custodians. The Trust will maintain control of the ether while it is staked because it will remain in the Trust’s account with the Custodians (i.e., it will be kept in a separate account for which the Trust is the beneficial and record owner and will not be commingled with other parties’ accounts with the Custodians). Staking will be a passive activity for the Trust, as it will not operate its own staking program. The Trust’s role will be limited to evaluating and contracting with one or more Staking Providers and instructing the Staking Provider on when to stake and/or unstake the Trust’s ether.

The rewards owed or paid to the Custodians as compensation for the Staking Services Providers reduce the amount of ether rewards that are generated from the Trust’s Staking Program that are available as the assets of the Trust. Each Staking Services Provider that generates staking rewards will be entitled to compensation determined as a portion of the staking rewards, which is generally expected to be determined by a fixed percentage of the overall rewards amount (the “Staking Provider Consideration”). The portion of the consideration paid to the Sponsor for arranging for the staking of the Trust’s ether (the “Sponsor’s Staking Portion”) will be comprised of an aggregate of 25% of the gross proceeds generated from staking (“Staking Consideration”). Of the Sponsor’s Staking Portion, the Sponsor will pay the Staking Services Provider for their services under the Staking Services Agreement and the Trust’s Custodians in connection with staking activities. The Trust will receive and retain the remainder of the gross Staking Consideration. The staking rewards earned by the Trust will accrue to the Trust’s account with the Custodians and will generally be staked in the same way as the Trust’s already staked ether. Block rewards and transaction fees are not considered staking rewards and will not accrete to the Trust.

The Trust may be negatively impacted by Staking Activities.

The Ethereum network uses a proof-of-stake consensus mechanism to secure and operate the network, meaning that the voting power of a validator in the network is determined by the amount of stake delegated to them by ether token holders. In proof-of-stake, validators risk or “stake” coins to compete to be randomly selected to validate transactions and are rewarded coins in proportion to the total amount of coins staked. The more stake delegated to a validator, the more voting power they have, the higher the likelihood is that the validator will be selected to propose and validate blocks and the higher the associated reward will be. This, in turn, leads to higher ether earnings for the ether tokenholders who chose to stake with the validator in question.

If an ether tokenholder chooses to engage in staking, they must either choose a specific validator to stake with or have sufficient ether to be selected as a validator by the Ethereum network themselves. The choice of validator can potentially impact the amount of staking rewards the tokenholder receives. The factors determining this amount include, but are not limited to:

If any Staking Services Provider experiences operational or other difficulties, terminates their services, fails to comply with regulations, raises their prices or disputes key intellectual property rights sold or licensed to, the Trust, the Trust could suffer losses. The Trust may also suffer the consequences of such Staking Services Provider’s mistakes. For example, if the Trust’s Custodians or Staking Services Provider selected to act as validators fail to behave as expected, default, fail to perform, suffer cybersecurity attacks, experience security issues or encounter other problems, the assets of the Trust may be irretrievably lost. The failure or capacity restraints of vendors and services, a cybersecurity breach involving any service providers or the termination or change in terms or price or commission rate of a vendor, third-party software license or service agreement on which the Trust relies, could disrupt the Trust’s Staking Activities or cause losses. Replacing any Staking Services Provider or addressing other issues with vendors and service providers could entail significant delay, expense and disruption for the Trust. As a result, if these vendors and service providers experience difficulties, are subject to cybersecurity breaches, terminate their services, dispute the terms of intellectual property agreements or raise their prices, and the Sponsor is unable to replace them with other vendors and service providers, particularly on a timely basis, the Trust’s Staking Activities could be interrupted or disrupted, and the Trust could suffer a loss.

The Ethereum network dictates requirements for participation in the network’s protocols and may reduce rewards if the relevant activities are not performed correctly. Malicious or poorly performing validators may also be “blacklisted”, meaning that ether tokenholders may decide to no longer delegate stake to such actors thereby resulting in such actors not being selected to validate and they would therefore be unable to receive staking rewards therefrom. Should any of the Trust’s Staking Services Providers engage in malicious activity or perform poorly, then such Staking Services Providers may be blacklisted which could negatively impact the Trust’s abilities to engage in Staking Activities and/or otherwise result in the Trust earning reduced staking rewards.

Staking requires that the Trust lock up the staked ether and become subject to an unbonding period to unstake the staked ether, meaning that the Trust cannot transfer the staked ether during the time that the ether is staked and during which it is being unbonded. The unbonding period may be longer than anticipated based on network activity. Note that the duration of the bonding period may depend on a range of factors including network load.

Due to the time involved in “exiting” the staking process, there is a risk that the Trust could become unable to timely meet excessive redemption requests in amounts that are greater than the portion of the Trust’s ether that remains un-staked, leading to temporary delays in settlement and, in extreme scenarios, the temporary unavailability of the Trust’s redemption program. Moreover, any staked ether which must be un-staked in order to fulfill a redemption (to the extent such redemption cannot be fulfilled utilizing the portion of the Trust’s ether that has not been staked, or through another mechanism to manage liquidity in connection with redemption orders) will be un-staked only after the redemption request is approved by the Trust, the Sponsor executes an un-stake or withdrawal transaction through the Custodians, and such transaction is processed by the Ethereum network. The Staking Provider will not be able to transfer unstaked ether or Staking Provider Consideration to another address on the Ethereum network.

In addition, depending on the anticipated length of the unbonding period, the staked ether may be classified as illiquid under the Trust’s liquidity risk management program. In addition, if ether is determined to be a security under the 1933 Act, it could be subject to significant constraints in terms of any transfer or disposal of such ether. In such event, the Trust may consider ether to be an “illiquid security”, which it defines as a security that the Trust reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the security.

Rewards for staked ether may be accrued even before the staked ether is unbonded. Once accrued, such ether rewards are considered part of the Trust’s assets, even if unbonding has not occurred. The Sponsor and the Trust will manage liquidity in accordance with the Trust’s liquidity risk policies and procedures and will monitor staking and bonding/unbonding activity closely on a daily basis. For more information on the Trust’s liquidity risk policies and procedures, see “Staking of the Trust’s Assets—Liquidity Risk Policies and Procedures.”

There is no guarantee that the Trust will receive any rewards with respect to staked ether. Past rewards are not indicative of future returns. The staking rewards that the Trust may receive from staking ether, if any, may be affected by, among other factors:

The Trust relies on the resources of the Staking Provider to facilitate the Sponsor’s staking activities. The Staking Provider will provide the hardware, software and services necessary to stake the ether from a validator node. The hardware and software utilized by the Staking Provider may prove to be inadequate to maximize the Trust’s staking revenue. The Trust is dependent on the hardware, software and services of the Staking Provider to effectively execute the staking activities. The Sponsor will have no ability to supervise or direct the conduct of the Staking Provider.

In addition, the Staking Provider Consideration will be paid from the proceeds of the staking program received by the Trust. The payment of the Staking Provider Consideration will reduce the portion of the staking rewards generated by the staking activities that are actually retained by the Trust. Accordingly, the staking rewards actually retained by the Trust will likely be less than what the Trust would retain if the Sponsor were to administer its own staking activities without the assistance of third-party service providers.

The Trust may vary the amount of ether to be staked and the rewards received may accordingly change from time to time.

The Trust’s staking model aims to maximize the portion of the Trust’s ether available for staking while controlling for liquidity and redemption risks. The model determines an optimal target range for the portion of assets staked, which is set by the Sponsor and which is based on factors including lock-up periods, historical and stressed redemption activity, Trust size, projected staking yields, staking provider reliability, secondary market liquidity, and broader market conditions (the “Utilization Rate”) by balancing expected yield against potential costs. While the Trust may stake a maximum of 100% of its ether holdings, the amount of ether that remains unstaked is determined based on the Trust’s Utilization Rate analysis, and accordingly may vary from time to time. Based on Utilization Rate analysis applied to historical data, the Trust generally intends to stake between 40% and 70% of the ether it holds, although the amount of ether that is staked may be lesser or greater from time to time. The precise percentage to be staked will be based on the estimated liquidity needs of the Trust, as determined by the Sponsor. Accordingly, changes in the percentage of ether holdings that are staked could impact the value of Shares held by investors.

Validation on the Ethereum network requires ether to be transferred into smart contracts on the underlying blockchain networks not under the Trust’s or anyone else’s control. If the Ethereum network source code or protocol fail to behave as expected, suffer cybersecurity attacks or hacks, experience security issues, or encounter other problems, such assets may be irretrievably lost. In addition, the Ethereum networks dictate requirements for participation in validation activity, and may impose penalties, or “slashing,” if the relevant activities are not performed correctly, such as if the staker acts maliciously on the network, “double signs” any transactions, or experience extended downtimes. Such penalties include the reduction of staking rewards for malicious actors and poorly performing validators and the “blacklisting” of such actors which may result in ether tokenholders no longer delegating their stakes to such actors thereby resulting in such actors not being selected to validate in the future. Should any of the Trust’s Staking Services Providers engage in malicious activity or perform poorly, then such Staking Services Providers may be blacklisted which could negatively impact the Trust’s abilities to engage in Staking Activities and/or otherwise result in the Trust earning reduced staking rewards. If validators’ staked ether are slashed by the Ethereum network, their assets may be confiscated, withdrawn, or burnt by the network, resulting in losses to them. Furthermore, the Ethereum network requires the payment of base fees and the practice of paying tips is common, and such fees can become significant as the amount and complexity of the transaction grows, depending on the degree of network congestion and the price of ether. Any cybersecurity attacks, security issues, hacks, penalties, slashing events, or other problems could damage validators’ willingness to participate in validation, discourage existing and future validators from serving as such, and adversely impact the Ethereum network’s adoption or the price of ether. Any disruption of validation on the Ethereum network could interfere with network operations and cause the Ethereum network to be less attractive to users and application developers than competing blockchain networks, which could cause the price of ether to decrease.

The portion of the consideration paid to the Sponsor for arranging for the staking of the Trust’s ether (the “Sponsor’s Staking Portion”) will be comprised of an aggregate of 25% of the gross proceeds generated from staking (“Staking Consideration”). Of the Sponsor’s Staking Portion, the Sponsor will pay the Staking Services Provider for their services under the Staking Services Agreement and the Trust’s Custodians in connection with staking activities. The Trust will receive and retain the remainder of the gross Staking Consideration. This arrangement creates a financial incentive for the Sponsor to maximize the amount of ether staked by the Trust, as higher levels of staked ether would generally result in greater staking rewards to the Sponsor. However, the Sponsor’s interest in maximizing staking rewards may conflict with the Trust’s need to maintain sufficient liquid ether to meet redemption requests and other operational requirements. If the Sponsor directs the Trust to stake excessive amounts of ether relative to the Trust’s liquidity needs, the Trust could become unable to timely meet redemption requests in amounts that are greater than the portion of the Trust’s ether that remains unstaked, leading to temporary delays in settlement and, in extreme scenarios, the temporary unavailability of the Trust’s redemption program.

While the Trust’s staking policies are designed to balance expected yield against potential risks and is based on various factors including historical redemption patterns and liquidity analysis, the Sponsor has sole discretion in determining the amount of ether to stake. Shareholders have no ability to influence or override the Sponsor’s determinations regarding staking levels. The Sponsor’s financial interest in staking rewards may cause it to prioritize staking income over maintaining adequate liquidity reserves, particularly during periods when staking yields are attractive relative to the costs and risks of maintaining liquid ether reserves.

Tax Risk

It is expected that each Shareholder will include in the computation of their taxable income their proportionate share of the taxable income and expenses of the Trust, including gains and losses realized in connection with the use of ether to pay Trust expenses or facilitate redemption transactions, as well as any amounts received in connection with staking, as applicable. The Trust does not anticipate making distributions to Shareholders, so any tax liability that a Shareholder incurs as a result of holding Shares will need to be satisfied from some other source of funds. If a Shareholder sells Shares in order to raise funds to satisfy such a tax liability, the sale itself may generate additional taxable gain or loss.

Ether staking may result in adverse tax consequences for Shareholders.

To the extent the Sponsor determines to stake a portion of the Trust’s ether, the staking of the Trust’s ether is expected to result in the Trust’s receipt of amounts received in connection with staking in the form of additional ether. Any such rewards are expected to be treated as ordinary income for U.S. federal income tax purposes. Thus, the Trust’s receipt of rewards derived from ether staking activities could result in beneficial owners of Shares incurring tax liability without an associated distribution from the Trust. Additionally, the Trust’s receipt of amounts received in connection with staking could have implications for investors sensitive to unrelated business taxable income, U.S. withholding taxes or taxable income effectively connected with a U.S. trade or business. The U.S. federal income tax treatment of staking may change from that described in the Trust’s prospectus filed with the SEC on October 8, 2025, possibly with retroactive effect.

As a grantor trust, the Trust can undertake only certain types of activities. For example, generally, the Trust cannot vary its investment portfolio to take advantage of market fluctuations. The Trust may receive income from investment activities that do not require such decision-making. The federal income tax treatment of staking for grantor trust purposes is uncertain pending additional IRS guidance. If the Trust were viewed as undertaking the types of activities that would not be allowable for U.S. federal income tax purposes, then the Trust could lose its income tax status as a grantor trust, and the Trust could be reclassified as a partnership. If the Trust were reclassified as a partnership, a more complex reporting regime would apply, and Shareholders would receive a Form K-1. If the Trust were reclassified as a partnership but did not satisfy a safe harbor or exception to the publicly traded partnership rules, it could be reclassified as a corporation, which would subject the Trust to corporate level tax, and the Shareholder’s return on investment would likely be affected.
