Statement Regarding Use of Non-GAAP Financial Measures

This Proxy Statement includes the following non-GAAP financial measure, which should be viewed in addition to, and not a substitute for or superior to, financial measures calculated in accordance with GAAP.

•Adjusted EBITDA. We calculate Adjusted EBITDA as net loss or income, adjusted to exclude provision for or benefit from income taxes, interest expense, depreciation and amortization expense, stock-based compensation expense, net gains or losses on our crypto assets held for investment, losses, net of recoveries, directly related to the data theft incident announced on the Current Report on Form 8-K we filed with the SEC on May 15, 2025 (the “Data Theft Incident”), including voluntary customer reimbursements, direct legal costs, and reward payments, if any, in connection with the threat actor’s arrest and conviction, and other income or expense, net, which represents net gains or losses on investments and other financial instruments, and other non-operating income and expense activity.

We believe that Adjusted EBITDA may be helpful to investors because it provides consistency and comparability with past financial performance. However, Adjusted EBITDA is presented for supplemental informational purposes only, has limitations as an analytical tool, and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. There are a number of limitations related to Adjusted EBITDA rather than net income, which is the nearest GAAP equivalent of Adjusted EBITDA.

In addition, other companies, including companies in our industry, may calculate Adjusted EBITDA differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our disclosure of Adjusted EBITDA as a tool for comparison. A reconciliation is provided below for Adjusted EBITDA to net income, the most directly comparable financial measure stated, in accordance with GAAP. Investors are encouraged to review the related GAAP financial measure and the reconciliation of Adjusted EBITDA to net income, and not to rely on any single financial measure to evaluate our business. For more information on Adjusted EBITDA for the year ended December 31, 2025, please see our Annual Report.
