3. Supplemental Information

Concentrations of Credit Risk

Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash, trade accounts receivable and our digital asset holdings.

Although we limit our exposure to credit loss by depositing our cash with established financial institutions that management believes have good credit ratings and represent minimal risk of loss of principal, our deposits, at times, may exceed Federal Deposit Insurance Corporation ("FDIC") insured limits. Cash and cash equivalents consist of demand deposits and highly liquid investments, such as money market funds, with original maturities of three months or less. As of March 31, 2026, the Company exceeded FDIC insurance limits in its insured bank accounts by approximately $2.7 million and held approximately $94.9 million in non-FDIC insured cash equivalent accounts. Included in cash equivalents are money market investments with original maturity dates when purchased of less than ninety days and are carried at fair value. Unrealized gains are included in interest income in the condensed consolidated statements of operations. As of December 31, 2025, we exceeded FDIC insurance limits by approximately $0.3 million in our insured bank accounts and held approximately $100.0 million non-FDIC insured cash equivalent accounts. The Company had no restricted cash as of March 31, 2026 and December 31, 2025.

There is currently no clearing house for our digital assets, including our bitcoin holdings, nor is there a central or major depository for the custody of our digital assets. There is a risk that some or all of our digital asset holdings could be lost or stolen. There can be no assurance that the exchanges or custodians will maintain adequate insurance or that such coverage will cover losses with respect to our digital asset holdings. Further, transactions denominated in digital assets are irrevocable. Stolen or incorrectly transferred digital assets may be irretrievable. As a result, any incorrectly executed transactions could adversely affect our financial condition.

Additional Disclosures

Refer to Note 7, "Commitments and Contingencies" in our Annual Report on Form 10-K filed with the SEC on March 27, 2026 for further discussion on our litigation settlement.

Loss per Common Share

Basic loss per common share is computed by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted loss per common share is computed by giving effect to all potential shares of common stock, including those related to our stock equity plans, to the extent dilutive. For all periods presented, these shares were excluded from the calculation of diluted loss per share of common stock because their inclusion would have been anti-dilutive. As a result, diluted loss per common share is the same as basic loss per common share for all periods presented.
