(13) Net Income (Loss) Per Share Attributable to Shareholders

For the three months ended and nine months ended September 30, 2024, basic net income (loss) per share is the same as diluted net income (loss) per share as the inclusion of any potential common shares outstanding would have been anti-dilutive. For the three months ended and nine months ended September 30, 2025, diluted net income (loss) per share is computed by applying the two-class method and then by dividing net income attributable to common stockholders by the weighted-average number of diluted common shares outstanding. The dilutive effect of potentially dilutive common shares is reflected in diluted earnings per share by application of the if-converted method for the Company’s outstanding preferred stock, the treasury stock method for the Company’s other potentially dilutive securities, and is ultimately applied by sequencing instruments beginning with those that are more dilutive.The following table sets forth the computation of basic and dilutive net income (loss) per share attributable to common stockholders for the three  and nine months ended September 30, 2025 and 2024 (in thousands, except per share amounts):
