Basic net income per share is computed by dividing net income by the weighted-average number of shares of the Company’s Class A Common Stock (“Class A Common Stock”) outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted-average number of shares of Class A Common Stock outstanding during the period, including potentially dilutive shares of Class A Common Stock equivalents outstanding during the period. The dilutive effect of potential shares of Class A Common Stock is determined using the treasury stock method. The following table sets forth the computation of basic and diluted net income per common share under the treasury stock method for the thirteen- and thirty-nine-week periods ended May 30, 2026 and May 31, 2025:

Potentially dilutive securities	—		208		—		170

Potentially dilutive securities attributable to outstanding share-based awards are excluded from the calculation of diluted net income per share when the combined exercise price and average unamortized fair value are greater than the average market price of Class A Common Stock, and, therefore, their inclusion would be anti-dilutive.
