Earnings (Loss) per Share [Abstract]

Note 3. Earnings (loss) per Share (EPS)

Basic earnings (loss) per share are based upon the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share are based upon the weighted average number of common shares outstanding during the period, assuming the issuance of common shares for all potentially dilutive common shares outstanding.

The following table sets forth the computation of basic and diluted earnings (loss) per share:

Of the options outstanding of 1,534,827 and 1,594,166 for the three and six-month periods ended July 5, 2026 and June 29, 2025, respectively, options to purchase 409,025 shares and 1,387,282 shares of common stock for the three and six-month periods ending July 5, 2026 and June 29, 2025, respectively, were not included in the computation of diluted earnings (loss) per share because they were anti-dilutive, as the exercise prices of the options were greater than the average market price of the common shares. Due to our net loss for the three-month period ended July 5, 2026 and the six-month periods ended July 5, 2026 and June 29, 2025, all options to purchase shares were anti-dilutive and were excluded for these periods.
