Earnings Per Share [Text Block] | (11) Net Loss per Share Basic loss per share is computed on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed on the basis of the weighted average number of shares of common stock plus the effect of potentially dilutive common shares outstanding during the period using the treasury stock method and the if-converted method. Potentially dilutive common shares include outstanding stock options and share-based awards. The following table reconciles the numerators and denominators used in the computations of both basic and diluted net loss per share

All unvested restricted stock awards for the years ended June 30, 2025 and 2024 are not included in diluted net loss per share, as the impact to net loss per share is anti-dilutive. Options to purchase 213,113 shares of common stock at exercise prices ranging from $5.50 to $175.50 per share outstanding for the year ended June 30, 2025 and options to purchase 156,628 shares of common stock at exercise prices ranging from $7.47 to $175.50 per share outstanding for the year ended June 30, 2024 were not included in diluted net loss per share, as the impact to net loss per share is anti-dilutive.
