Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share Basic earnings (loss) per common share is computed by dividing net earnings (loss) available to the common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings (loss) per common share is computed by dividing the diluted earnings (loss) available to the common shareholders by the weighted-average number of shares of common stock and potentially dilutive shares of common stock outstanding during the period. The dilutive effect of equity awards is calculated based on the average stock price for each fiscal period, using the treasury stock method. The shares of Coherent Common Stock issuable upon conversion of the Series B Convertible Preferred Stock are calculated under the If-Converted method. For the years ended June 30, 2025, June 30, 2024 and June 30, 2023, as the Company was in a net loss position, there were no dilutive shares. For the years ended June 30, 2025, June 30, 2024 and June 30, 2023, diluted earnings (loss) per share excluded the potentially dilutive effect of the performance and restricted shares, as well as the shares of Coherent Common Stock issuable upon conversion of the Series B Convertible Preferred Stock as their effects were anti-dilutive. The following is a reconciliation of the numerators and denominators of the basic and diluted earnings (loss) per share computations for the periods presented ($000, except per share):
