Earnings Per Share [Abstract]
Earnings (Loss) Per Share	NOTE 4 EARNINGS (LOSS) PER SHARE Basic income (loss) per share is computed by dividing our net income (loss) by the weighted average number of shares of our Common Stock outstanding during the period. For diluted earnings per share, the dilutive impact of stock options and warrants is determined by applying the “treasury stock” method. The dilutive impact of the 2029 Convertible Notes and the 2033 Senior Notes (each as defined in Note 7) has been considered using the “if converted” method. For periods in which their effect would have been antidilutive, no effect is given in the dilutive computation to Common Stock issuable under outstanding options or warrants or the potentially dilutive shares issuable pursuant to the 2029 Convertible Notes and 2033 Senior Notes. A total of 110,081,119 and 126,349,239 potential shares of Common Stock were excluded from the calculation of diluted net loss per share for the three months ended June 30, 2026 and 2025, respectively, because their inclusion would have been antidilutive. A total of 109,739,192 and 216,845,048 potential shares of Common Stock were excluded from the calculation of diluted net loss per share for the six months ended June 30, 2026 and 2025, respectively, because their inclusion would have been antidilutive. During the three and six months ended June 30, 2026, no options were exercised, and 847,655 restricted stock units vested, resulting in the issuance of 546,074 shares of Common Stock. During the three months ended June 30, 2025, 1,250 options were exercised, and 553,822 restricted stock units vested, resulting in the issuance of 384,606 shares of Common Stock. During the six months ended June 30, 2025, 57,500 options were exercised, and 553,822 restricted stock units vested, resulting in the issuance of 440,856 shares of Common Stock.

NOTE 4 EARNINGS (LOSS) PER SHARE

Basic income (loss) per share is computed by dividing our net income (loss) by the weighted average number of shares of our Common Stock outstanding during the period. For diluted earnings per share, the dilutive impact of stock options and warrants is determined by applying the “treasury stock” method. The dilutive impact of the 2029 Convertible Notes and the 2033 Senior Notes (each as defined in Note 7) has been considered using the “if converted” method. For periods in which their effect would have been antidilutive, no effect is given in the dilutive computation to Common Stock issuable under outstanding options or warrants or the potentially dilutive shares issuable pursuant to the 2029 Convertible Notes and 2033 Senior Notes.

A total of 110,081,119 and 126,349,239 potential shares of Common Stock were excluded from the calculation of diluted net loss per share for the three months ended June 30, 2026 and 2025, respectively, because their inclusion would have been antidilutive. A total of 109,739,192 and 216,845,048 potential shares of Common Stock were excluded from the calculation of diluted net loss per share for the six months ended June 30, 2026 and 2025, respectively, because their inclusion would have been antidilutive.

During the three and six months ended June 30, 2026, no options were exercised, and 847,655 restricted stock units vested, resulting in the issuance of 546,074 shares of Common Stock.

During the three months ended June 30, 2025, 1,250 options were exercised, and 553,822 restricted stock units vested, resulting in the issuance of 384,606 shares of Common Stock.

During the six months ended June 30, 2025, 57,500 options were exercised, and 553,822 restricted stock units vested, resulting in the issuance of 440,856 shares of Common Stock.
