(Unaudited)

Of the options outstanding of 1,596,748 and 1,671,687 for the three-month periods ended March 30, 2025 and March 31, 2024, respectively, options to purchase 1,596,748 shares and 900,163 shares of common stock for the three-month periods ending March 30, 2025 and March 31, 2024, 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.
