What changed since the prior 10-K

New

  • New

    Unlike some digital assets, which have a limit on outstanding supply, there is no limit on ether supply

    Unlike some digital assets with a hard cap, ether has no limit on its supply and will continue to be issued to validators, which could be inflationary and reduce its value.

  • New

    Digital asset treasury companies risk

    Non-crypto companies holding corporate treasuries in digital assets could create procyclical price volatility and downward pressure on ether prices during market downturns.

  • New

    Operational cost may exceed the award for validating transaction, and increased transaction fees may adversely affect the usage of the Ethereum network

    High transaction fees could deter Ethereum network usage, while low validation rewards could cause validators to operate at a loss or cease operations.

  • New

    If regulators or public utilities take actions that restrict or otherwise impact mining activities, such actions could result in decreased security of a digital asset network, including the Ethereum network, which could adversely affect the value of the Shares

    Energy consumption concerns and state-level mining restrictions could reduce the security of proof-of-stake networks like Ethereum and create negative market sentiment.

  • New

    Additionally, miners on proof-of-work networks may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed

    Miners on proof-of-work networks may face power outages or higher electricity prices, which could indirectly impact proof-of-stake network sentiment and share value.

  • New

    Any of these factors could adversely affect the performance of the Trust and the value of the Shares

    Difficulties in share creation and redemption by Authorized Participants or custodians could cause the share price to diverge from the net asset value of ether.

  • New

    The Shares may trade at a price that is at, above or below the Trust’s NAV as a result of the non-current trading hours between NASDAQ and the digital asset market

    Non-current trading hours between NASDAQ and the 24-hour digital asset market could cause share prices to gap down when the exchange reopens after negative ether price moves.
