Evaluation of Disclosure and Control Procedures

The Company’s management, with the participation of the Chief Executive Officer and Chief Financial Officer, after evaluating the effectiveness of the Company’s “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this report, have concluded that our disclosure controls and procedures are effective at the reasonable assurance level and are designed to ensure that the information we are required to disclose is recorded, processed, summarized and reported within the necessary time periods. Our disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in reports that we file or submit pursuant to the Securities Exchange Act of 1934, as amended, is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

As required by Rule 13a-15(c) promulgated under the Exchange Act, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our internal control over financial reporting as of December 31, 2025. Management’s assessment was based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013 Framework) (the COSO Framework). Based on management’s assessment, management has concluded that our internal control over financial reporting was effective as of December 31, 2025.

This Form 10-K does not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by our independent registered public accounting firm pursuant to the rules of the SEC that permit us to provide only management’s report in this Form 10-K.

Changes in Internal Control over Financial Reporting

In 2025, we began the implementation of our ETH Treasury Management Strategy (“ETH Strategy”), as further described in notes to the accompanying consolidated financial statements, included in Item 8 of this annual report. Accordingly, and as previously disclosed in our quarterly reports on Form 10-Q, we have implemented new and additional internal controls surrounding the acquisition, safeguarding, custody, accounting, and reporting of our digital assets. These changes included implementation and enhancement of policies, processes, people, technology and operations related to our ETH Strategy, were completed in the fourth quarter of 2025, and were evaluated in our assessment of internal control over financial reporting above. Other than the changes related to the ETH Strategy described herein, there were no changes in the Company’s internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) during the quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Inherent Limitations on the Effectiveness of Controls

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, in designing and evaluating the disclosure controls and procedures, management recognizes that any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only provide reasonable, not absolute assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business but cannot assure you that such improvements will be sufficient to provide us with effective internal control over financial reporting.
