2. Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding. Diluted net income per share is computed by dividing net income by the weighted-average number of shares of common stock and dilutive potential common stock equivalents then outstanding. Dilutive potential common stock equivalents include the assumed exercise, vesting and issuance of employee stock awards using the treasury stock method, as well as common stock issuable upon assumed conversion of our convertible senior notes due 2025 (the “2025 Notes”) and our convertible senior notes due 2028 (the “2028 Notes”) using the if-converted method. If in a net loss position, diluted net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding for the period, without consideration for dilutive potential common stock equivalents.

The following table shows the computation of basic and diluted net income (loss) per share for the three and six months ended June 30, 2025 and 2024:
