Basic and diluted net income (loss) per share for the three and six months ended June 30, 2025 and 2024 were calculated as follows (in thousands, except per share amounts):

Weighted average shares of common stock outstanding: diluted	219,886		206,425		217,574		206,244

The Company’s potentially dilutive securities include outstanding stock options, unvested restricted stock units and shares issuable under the employee stock purchase plan for the three and six months ended June 30, 2025 and 2024.

For the three and six months ended June 30, 2025, the dilutive effect of outstanding stock options, restricted stock unit awards, and shares issuable under the employee stock purchase plan was calculated using the treasury method, whereby all such awards are assumed to be exercised at the beginning of the period. The hypothetical proceeds from such exercises, including the average unrecognized stock compensation expense for outstanding stock options, restricted stock units and shares issuable under the employee stock purchase plan, were assumed to be used to purchase outstanding common stock at the average price during the period. The net share impact of dilutive securities was added to the weighted average basic common shares outstanding to calculate weighted average diluted shares outstanding.

For the three and six months ended June 30, 2024, during which the Company recorded a net loss, all potentially dilutive securities have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share, and thus they are considered “anti-dilutive.” For this period, the weighted average number of shares of common stock outstanding used to calculate both basic and diluted net loss per share of common stock is the same.

The following table summarizes potential shares of common stock that were excluded from the computation of diluted net income (loss) per share attributable to common stockholders as they were anti-dilutive:
