Key Points from the Report

1. Structure and Operations

• The ARK 21Shares Bitcoin ETF provides direct exposure to bitcoin, with shares reflecting the price of the underlying asset.
• The ETF creates and redeems shares in large blocks called “Baskets” (5,000 shares or more), only available to authorized participants (registered broker-dealers).
• The Bank of New York Mellon serves as both Transfer Agent and Cash Custodian, while Foreside Global Services acts as Marketing Agent. The ETF’s bitcoin is held by qualified custodians.
• The Trust operates as a grantor trust and is not registered as a commodity pool or investment adviser.

2. Financial Highlights

• Aggregate market value of public float: \$5,034,361,000 as of June 30, 2025.
• Shares outstanding: 107,550,000 as of February 26, 2026.
• All required reports (10-K, 10-Q, 8-K) are made available on the sponsor’s website after filing with the SEC.

3. Regulatory and Reporting Status

• The ETF is not a “well-known seasoned issuer” and is not required to file as an emerging growth company.
• It is not a shell company and has complied with all reporting requirements for the past year.
• Internal controls have been attested to by an independent auditor, and no correction of prior financial statement errors was reported.

4. Major Risks and Shareholder Considerations

Bitcoin-Specific Risks

• The value of ARKB shares is directly tied to bitcoin’s price, which remains highly volatile and subject to dramatic swings.
• Bitcoin and blockchain technology are relatively new innovations with a limited operating history, making valuations difficult and unpredictable.
• Operational risks include security breaches, theft, fraud, and loss of private keys—potentially resulting in irretrievable loss of assets.
• Technological risks such as forks, protocol changes, and advances in quantum computing could impact bitcoin’s value.
• Market manipulation, wash trading, and front-running are noted as ongoing concerns in digital asset markets, with the SEC specifically highlighting these risks.

ETF-Specific and Structural Risks

• Share values may diverge from Net Asset Value (NAV), especially if the arbitrage mechanism is not functioning efficiently or if authorized participants cannot hedge exposures.
• The ETF is concentrated solely in bitcoin, exposing investors to single-asset risk and potential illiquidity during market stress.
• Asset dilution: The amount of bitcoin backing each share will decline over time due to fees and expenses.
• Possible absence of active authorized participants could impact share liquidity and investor exit options.
• Shareholders have limited rights compared to holders of mutual funds or traditional ETFs—no claim on forked assets, limited voting rights, and are not protected by the 1940 Act or CEA.

Regulatory and Taxation Risks

• Future regulatory actions by U.S. or foreign governments could adversely impact ARKB’s operations and the price of bitcoin.
• If the ETF, sponsor, or authorized participants are deemed to be operating as “money service businesses,” they may face additional regulatory and compliance costs.
• Shareholders may incur tax liabilities without receiving a corresponding distribution, particularly in the case of sales of bitcoin for fees or expenses or as a result of blockchain forks.
• Tax treatment of bitcoin remains unsettled at state and local levels, and hard forks may result in unexpected tax consequences.

Industry-Wide and Systemic Risks

• Events such as the failure or hacking of major digital asset platforms (e.g., FTX, Celsius, Voyager) have previously led to significant volatility and loss of confidence in crypto markets.
• Stablecoins, which provide liquidity to digital asset markets, are themselves reliant on the traditional banking system—any disruption could impact bitcoin’s liquidity and price.
• Concentration of service providers (custodians, prime brokers) across the industry could magnify operational risks if one key provider experiences a disruption or loss of confidence.

5. Forward-Looking Statements and Cautionary Notes

• The report contains numerous forward-looking statements regarding market developments, regulatory changes, and the future performance of bitcoin and the ETF. Actual outcomes may vary materially due to numerous risks and uncertainties.
• The sponsor, sub-adviser, and trust do not undertake to update forward-looking statements except as required by law.

Potential Price Sensitive Information

• Volatility in bitcoin prices, regulatory changes, operational failures, or loss of key personnel could have a significant impact on the share price of ARKB.
• Any major incident affecting digital asset market infrastructure (e.g., hacking, regulatory crackdown, failure of service providers) could trigger sharp declines or trading halts in ARKB shares.
• The ETF’s structure and regulatory classification mean it does not enjoy certain investor protections, which could elevate perceived risk and affect market demand for shares.
• Investors should be aware that the amount of bitcoin backing each share declines over time due to operational costs and fees, which could impact long-term value.

Conclusion

The ARK 21Shares Bitcoin ETF’s annual report highlights both the opportunities and substantial risks associated with investing in a product tied directly to bitcoin. While the ETF has grown to a multi-billion dollar public float and is fully compliant with reporting requirements, investors must be mindful of the unique risks inherent in digital asset markets. Significant volatility, regulatory uncertainty, operational risks, and the absence of certain statutory protections all have the potential to materially impact the value of ARKB shares. Shareholders and prospective investors are encouraged to carefully review the detailed risk disclosures in the annual report and to remain vigilant to ongoing developments in the digital asset space.
