Earnings Per Share [Abstract] |
Net Loss Per Share | 3. Net Loss Per Share Basic net loss per share is based on the weighted average number of common shares outstanding during each year. Diluted net loss per share is computed using the treasury stock method by dividing net loss by the weighted average number of shares of common stock outstanding. The following table presents the net loss per share calculations:
|  | Year Ended May 31, |
|  | 2026 |  |  | 2025 |  |  | 2024 |
Numerator for basic and diluted net loss per share — Net Loss |  | $ | (7.9 | ) |  | $ | (1,092.0 | ) |  | $ | (9.4 | )
Denominator for basic net loss per share — Weighted average shares |  |  | 217.5 |  |  |  | 216.9 |  |  |  | 216.5 |
Effect of dilutive stock options and restricted stock units |  |  | — |  |  |  | — |  |  |  | — |
Denominator for diluted net loss per share |  |  | 217.5 |  |  |  | 216.9 |  |  |  | 216.5 |
Net loss attributable per share |  |  |  |  |  |  |  |  |
Basic |  | $ | (0.04 | ) |  | $ | (5.03 | ) |  | $ | (0.04 | )
Diluted |  | $ | (0.04 | ) |  | $ | (5.03 | ) |  | $ | (0.04 | )
Certain outstanding options and restricted stock units ("RSUs") were excluded from the computation of diluted earnings per share because the effect would have been anti-dilutive. These potential dilutive common shares, which may be dilutive to future diluted earnings per share, are as follows:
|  | Year Ended May 31, |
|  | 2026 |  |  | 2025 |  |  | 2024 |
Anti-dilutive options and RSUs excluded from EPS Computation (1) |  |  | 1.0 |  |  |  | 0.1 |  |  |  | 0.3 |
(1) Due to the net loss in fiscal years 2026, 2025 and 2024, the dilutive stock options and RSUs were anti-dilutive.
