Earnings Per Share [Text Block] | 6. Basic and Diluted Net Income (Loss) Per Share Basic net income (loss) per share is computed by dividing the income or loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted net income (loss) per share reflects the dilution of common stock equivalents such as options, convertible debt, and warrants to the extent the impact is dilutive. The following table shows the number of potentially dilutive shares excluded from the diluted net income (loss) per share calculation as of September 30, 2025 and 2024:
| As of
| September 30, 2025 | September 30, 2024
Common stock options and warrants |  | 9,139 |  | 7,728
Debt with conversion feature at $30 per share of common stock |  | 1,161 |  | 1,151
