______________________________
(1)    The dilutive effect of all potentially dilutive common shares is calculated using the treasury stock method. Certain potentially dilutive common shares issuable are not included in the computation of diluted net income per share because to do so would be anti-dilutive. For the three and nine months ended September 30, 2025, 532,000 and 265,000 shares were excluded from diluted shares outstanding. For the three and nine months ended September 30, 2024, 196,000 and 102,000 shares, respectively, were excluded from diluted shares outstanding.
