SUBJECT TO COMPLETION, DATED MAY 30, 2024
PRELIMINARY PROSPECTUS
GRAYSCALE ETHEREUM TRUST (ETH)
Grayscale Ethereum Trust (ETH) (the Trust) is a Delaware statutory trust that issues common units of fractional undivided beneficial interest
(Shares), which represent ownership in the Trust. The Trusts purpose is to hold Ether, which are digital assets that are created and transmitted through the operations of the peer-to-peer Ethereum Network, a decentralized network of computers that operates on cryptographic protocols. The Trusts investment objective is for the value of the Shares (based on Ether per Share) to
reflect the value of Ether held by the Trust, as determined by reference to the Index Price (as defined herein), less the Trusts expenses and other liabilities. While an investment in the Shares is not a direct investment in Ether, the Shares
are designed to provide investors with a cost-effective and convenient way to gain investment exposure to Ether. Grayscale Investments, LLC is the sponsor of the Trust (the Sponsor), CSC Delaware Trust Company is the trustee of the Trust
(the Trustee), The Bank of New York Mellon is the transfer agent of the Trust (in such capacity, the Transfer Agent) and the administrator of the Trust (in such capacity, the Administrator), Coinbase, Inc. is the
prime broker of the Trust (the Prime Broker) and Coinbase Custody Trust Company, LLC is the custodian of the Trust (the Custodian).
The Shares have been approved for listing on NYSE Arca, Inc. (NYSE Arca) under the symbol ETHE. It is expected that the Shares will be
sold to the public at varying prices to be determined by reference to, among other considerations, the price of Ether and the trading price of the Shares on the NYSE Arca at the time of each sale.
The Shares may be purchased from the Trust only in one or more blocks of 10,000 Shares after the Amended Trust Agreement (as defined herein) becomes
effective, or 100 Shares prior to such time (a block of such number of Shares is called a Basket). The Trust issues Baskets of Shares to certain authorized participants (Authorized Participants) on an ongoing basis as
described in Plan of Distribution. In addition, the Trust redeems Shares in Baskets on an ongoing basis from Authorized Participants. The Trust is currently able to accept Cash Orders (as defined herein), pursuant to which an Authorized
Participant will deposit cash into, or accept cash from, the Cash Account in connection with the creation and redemption of Baskets, and a third party (a Liquidity Provider) that is not an agent of, or otherwise acting on behalf of, such
Authorized Participant will obtain or receive Ether in exchange for cash in connection with such order. However, and in common with other spot digital asset exchange-traded products, the Trust is not at this time able to create and redeem shares via
in-kind transactions with Authorized Participants, and there has yet to be definitive regulatory guidance on whether and how registered broker-dealers can hold and deal in Ether in compliance with the federal
securities laws. To the extent further regulatory clarity emerges, the Sponsor expects NYSE Arca to seek the necessary regulatory approval to amend its listing rules to permit the Trust to do so (the
In-Kind Regulatory Approval). Subject to NYSE Arca seeking and obtaining In-Kind Regulatory Approval, in the future the Trust may also create and redeem
Shares via in-kind transactions with Authorized Participants or their designees (any such designee, an AP Designee) in exchange for Ether. There can be no assurance as to when such regulatory
clarity will emerge, or when NYSE Arca will seek or obtain such regulatory approval, if at all. See Description of Creation and Redemption of Shares. Some of the activities of the Authorized Participants will result in their being deemed
participants in a distribution in a manner which would render them statutory underwriters and subject them to the prospectus-delivery and liability provisions under the Securities Act of 1933, as amended (the Securities Act). See
Plan of Distribution. As of May 28, 2024, the number of Ether required to create a Basket of 100 Shares is approximately 0.94552590 Ether and the number of Ether required to create a Basket of 10,000 Shares after giving effect to the
Amended Trust Agreement would have been 94.552590 Ether.
In addition, and in common with other spot Ether exchange-traded products at this time, neither
the Trust, nor the Sponsor, nor the Custodian, nor any other person associated with the Trust will, directly or indirectly, engage in Staking (as defined herein), meaning no action will be taken pursuant to which any portion of the Trusts
Ether becomes subject to Ethereum proof-of- stake validation or is used to earn additional Ether or generate income or other earnings, and there can be no assurance that the Trust, the Sponsor, the Custodian or any other person associated with the
Trust will ever be permitted to engage in such activity in the future.
Investing in the Shares involves significant risks. You should carefully consider
the risk factors described beginning on page 18 in this prospectus, in Part IItem 1A. Risk Factors beginning on page 47 in our Annual Report on Form 10-K
for the fiscal year ended December 31, 2023, in Part IIItem 1.A. Risk Factors beginning on page 22 in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2024, in any applicable prospectus supplement and in the
other documents incorporated or deemed incorporated by reference herein before you invest in the Shares.
Neither the Securities and
Exchange Commission nor any state securities commission has approved or disapproved of the securities offered in this prospectus, or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.
The Shares are neither interests in nor obligations of the Sponsor or the Trustee.
The U.S. dollar value of a Basket of Shares at 4:00 p.m., New York time, on the trade date of a creation or redemption order is equal to the Basket
Amount, which is the number of Ether required to create or redeem a Basket of Shares, multiplied by the Index Price, which is the U.S. dollar value of an Ether derived from the Digital Asset Trading Platforms (as defined herein)
that are reflected in the CoinDesk Ether Price Index (ETX) (the Index), calculated at 4:00 p.m., New York time, on each business day. The Index Price is calculated using non-GAAP methodology and is
not used in the Trusts financial statements.
