Earnings Per Share [Text Block] | Note 9 — Basic and Diluted Net Loss per Common Share For the three months ended March 31, 2026 and 2025, basic and diluted net income (loss) per share is computed using the weighted average number of shares of common stock outstanding during the period and includes common stock equivalents (using the treasury stock and “if converted” method) from stock options, RSUs, ESPP and warrants. For the three months ended March 31, 2025, 4,130,700, in common stock equivalents are excluded from the calculation of diluted net loss per share because the effect was anti-dilutive. During the three months ended March 31, 2026 and 2025, included in the basic and diluted net loss per share calculation were RSUs awarded to directors that had vested, but the issuance and delivery of the shares are deferred until the director retires from service as a director. The following table shows the computation of basic and diluted net loss per common share:
