Basic net income per share is computed using the weighted average number of shares of common stock outstanding for the period, excluding unvested RSUs and stock options. Diluted net income per share is based upon the weighted average shares of common stock outstanding for the period plus dilutive potential shares of common stock, including unvested RSUs and stock options using the treasury stock method.

The following table sets forth the computation of basic and diluted net income per share for the three and six months ended June 30, 2026 and 2025 (in thousands, except for per share data):
