Note 3. Earnings (Loss) Per Share

Basic earnings (loss) earnings (loss) per share is based on the weighted-average effect of all common shares issued and outstanding and is calculated by dividing net income (loss) attributable to common stockholders by the weighted-average shares outstanding during the period. Diluted earnings (loss) per share is calculated by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares used in the basic earnings (loss) per share calculation plus the number of common shares that would be issued assuming exercise or conversion of all potentially dilutive common shares outstanding.

Greystone's Series 2003 preferred stock, which is convertible into 1,933,333 shares of common stock, was not included in the computation of diluted earnings per share for the nine months and three months ended February 28, 2025 as the effect would have been antidilutive. As of May 31, 2025, all preferred stock had been retired and was therefore not included in the computation for the nine months and three months ended February 28, 2026. Warrants exercisable into common stock totaling $500,000 were also not included in the computation of diluted loss per share for the nine months and three months ended February 28, 2026, respectively, as the effect would have been antidilutive.

The following tables set forth the computation of basic and diluted (loss) earnings per share.
