Risk factors and legal proceedings

The risks Ark 21Shares Bitcoin ETF names in Item 1A of its 10-K filed Mar 2, 2026: 76 risks under these headings, as written.3

  • Risks Associated with Bitcoin and the Bitcoin Network
  • Bitcoin is a relatively new technological innovation with a limited operating history.
  • Bitcoin generally.
  • Limits on bitcoin supply.
  • The trading prices of many digital assets, including bitcoin, 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 bitcoin, could have a material adverse effect on the value of the Shares and the Shares could lose all or substantially all of their value.
  • Spot markets on which bitcoin trades are relatively new and largely unregulated.
  • The use of cash creations and redemptions, as opposed to in-kind creations and redemptions, may adversely affect the arbitrage transactions by Authorized Participants intended to keep the price of the Shares closely linked to the price of bitcoin and, as a result, the price of the Shares may fall or otherwise diverge from NAV.
  • Authorized Participants may act in the same or similar capacity for other competing products.
  • Spot markets may be exposed to security breaches.
  • Spot markets may be exposed to fraud and market manipulation.
  • Spot markets may be exposed to wash trading.
  • Spot markets may be exposed to front-running.
The other 65 risks
  • The market value of bitcoin is subject to momentum pricing.
  • A decline in the adoption of bitcoin or the Bitcoin network could negatively impact the Trust.
  • The failure or poor performance of, or perceptions of risk or negative publicity around one or more of the protocols based on the Bitcoin network or that make use of bitcoin may adversely affect demand for bitcoin, the price of bitcoin, or the price of the Shares.
  • Irrevocable nature of blockchain-recorded transactions.
  • The loss or destruction of a private key required to access bitcoin may be irreversible.
  • Loss of a critical banking relationship for, or the failure of a bank used by, the Trust or the Prime Broker could adversely impact the Trust’s ability to create or redeem Baskets, or could cause losses to the Trust.
  • If any of the Custodial Services Agreements or the Prime Broker Agreement are terminated or the Bitcoin Custodians or the Prime Broker fail to provide services as required, the Trustee may need to find and appoint a replacement custodian or prime broker, which could pose a challenge to the safekeeping of the Trust’s bitcoin, and the Trust’s ability to continue to operate may be adversely affected.
  • The Bitcoin Custodians and the Prime Broker may act in the same or similar capacity for other competing products.
  • The Prime Broker routes orders through Connected Trading Venues in connection with trading services under the Prime Broker Agreement. The loss or failure of any such Connected Trading Venues may adversely affect the Prime Broker’s business and cause losses for the Trust.
  • A disruption of the Internet may affect Bitcoin operations, which may adversely affect the bitcoin industry and an investment in the Trust.
  • Potential changes to the Bitcoin network’s protocols and software could, if accepted and authorized by the Bitcoin network community, adversely affect an investment in the Trust.
  • The open-source structure of the Bitcoin network protocol means that the core developers and other contributors are generally not directly compensated for their contributions in maintaining and developing the Bitcoin network protocol. A failure to properly monitor and upgrade the Bitcoin network protocol could damage the Bitcoin network and an investment in the Trust.
  • Decentralized governance of the Bitcoin network could have a negative impact on the performance of the Trust.
  • Anonymity and illicit financing risk.
  • The actual or perceived use of bitcoin and other digital assets in illicit transactions may adversely affect the bitcoin industry and an investment in the Trust.
  • The inability to recognize the economic benefit of a “fork” or an “airdrop” could adversely impact an investment in the Trust.
  • Network Forks.
  • Bitcoin is subject to cybersecurity risks, which could adversely affect an investment in the Trust or the ability of the Trust to operate.
  • If miners expend less processing power on the Bitcoin network, it could increase the likelihood of a malicious actor obtaining control.
  • Cancer nodes.
  • Double-spending risks.
  • Flaws in source code.
  • Mathematical or technological advances could undermine the Bitcoin network’s consensus mechanism.
  • The Bitcoin network faces scaling challenges and efforts to increase the volume of transactions may not be successful.
  • New competing digital assets may pose a challenge to bitcoin’s current market position, resulting in a reduction in demand for bitcoin, which could have a negative impact on the price of bitcoin and may have a negative impact on the performance of the Trust.
  • Competition from central bank digital currencies (“CBDCs”) could adversely affect the value of bitcoin and other digital assets.
  • Prices of bitcoin may be affected due to stablecoins, the activities of stablecoin issuers and their regulatory treatment.
  • Operational cost may exceed the award for solving blocks or transaction fees, and increased transaction fees may adversely affect the usage of the Bitcoin network.
  • Electricity usage.
  • Miners could act in collusion to raise transaction fees, which may adversely affect the usage of the Bitcoin network.
  • As technology advances, miners may be unable to acquire the digital asset mining hardware necessary to develop and launch their operations. A decline in the bitcoin mining population could adversely affect the Bitcoin network and an investment in the Trust.
  • If profit margins of bitcoin mining operations are not high, miners may elect to immediately sell bitcoin earned by mining, resulting in a reduction in the price of bitcoin that could adversely affect an investment in the Trust.
  • Large-scale sales or distributions.
  • Congestion or delay in the Bitcoin network may delay purchases or sales of bitcoin by the Trust.
  • Risks Associated with Investing in the Trust
  • Investment related risks.
  • Deviations between the Trust’s NAV and NAV per Share versus the Trust’s Principal Market NAV and Principal Market NAV per Share may occur.
  • If the process of creation and redemption of Baskets encounters any unanticipated difficulties, the possibility for arbitrage transactions by Authorized Participants intended to keep the price of the Shares closely linked to the price of bitcoin may not exist and, as a result, the price of the Shares may fall or otherwise diverge from NAV.
  • Owning Shares is different from directly owning bitcoin.
  • Index tracking risk.
  • Liquidity risk.
  • Counterparty risk.
  • The value of the Shares may be influenced by a variety of factors unrelated to the value of bitcoin.
  • The Administrator is solely responsible for determining the value of the Trust’s bitcoin, the Trust’s NAV and the Trust’s Principal Market NAV. The value of the Shares may experience an adverse effect in the event of any errors, discontinuance or changes in such valuation calculations.
  • Bitcoin Counterparties’ buying and selling activity associated with the creation and redemption of Baskets may adversely affect an investment in the Shares.
  • The inability of Bitcoin Counterparties to hedge their bitcoin exposure may adversely affect the liquidity of Shares and the value of an investment in the Shares.
  • Arbitrage transactions intended to keep the price of Shares closely linked to the price of bitcoin may be problematic if the process for the creation and redemption of Baskets encounters difficulties, which may adversely affect an investment in the Shares.
  • Security threats and cyber-attacks could result in the halting of Trust operations and a loss of Trust assets or damage to the reputation of the Trust, each of which could result in a reduction in the price of the Shares.
  • The Bitcoin Custodians could become insolvent.
  • The Trust is subject to risks due to its concentration of investments in a single asset.
  • A lack of active trading markets for the Shares may result in losses on Shareholders’ investments at the time of disposition of Shares.
  • Several factors may affect the Trust’s ability to achieve its investment objective on a consistent basis.
  • The amount of bitcoin represented by the Shares will decline over time.
  • The development and commercialization of the Trust is subject to competitive pressures.
  • A loss of confidence in or breach of a Bitcoin Custodian may adversely affect the Trust and the value of an investment in the Shares.
  • The Sponsor may need to find and appoint a replacement custodian or prime broker quickly, which could pose a challenge to the safekeeping of the Trust’s bitcoin.
  • Lack of recourse.
  • The value of the Shares will be adversely affected if the Trust is required to indemnify the Sponsor, the Sub-Adviser, the Trustee, the Administrator, the Transfer Agent, the Bitcoin Custodians, or the Prime Broker.
  • Intellectual property rights claims may adversely affect the Trust and the value of the Shares.
  • Amendment of Trust Agreement without shareholder consent.
  • Potential conflicts of interest may arise among the Sponsor or its affiliates and the Trust. The Sponsor and its affiliates have no fiduciary duties to the Trust and its shareholders other than as provided in the Trust Agreement, which may permit them to favor their own interests to the detriment of the Trust and its shareholders.
  • Unforeseeable risks.
  • Risks Associated with the Index and Index Pricing
  • The Index has a limited history.
  • Right to change index.
  • Risks related to pricing.
  • Regulatory Risk
  • Bitcoin’s status as being offered or sold as a “security” under U.S. federal securities laws remains unsettled.
