10. INCOME (LOSS) PER SHARE OF COMMON STOCK

Basic net income (loss) per share attributable to common stockholders, amounts are computed by dividing the net income (loss) plus preferred stock dividends and deemed dividends on preferred stock by the weighted average number of shares outstanding during the year.

Diluted net income (loss) per share attributable to common stockholders amounts are computed by dividing the net income (loss) plus preferred stock dividends, deemed dividends on preferred stock, after-tax interest on convertible debt and convertible dividends by the weighted average number of shares outstanding during the year, plus convertible preferred stock, convertible debt, convertible preferred dividends, warrants and stock options convertible into common stock shares.

During a period of net loss, basic and diluted earnings per share are the same as the assumed exercise of warrants and the conversion of convertible debt and preferred stock are anti-dilutive. For the six months ended June 30, 2026 and 2025, all stock options, convertible preferred stock, convertible debt, convertible deferred compensation and warrants were anti-dilutive and were therefore excluded from the computation of diluted loss per share. At June 30, 2026 and 2025, these instruments were convertible into 45,157,140 and 55,565,088 common shares, respectively.
