Net Loss Per Common Share

6 Months Ended

Jun. 30, 2024

Basic net loss per common share is computed by dividing the net loss attributable to Xencor by the weighted-average number of common shares outstanding during the period without consideration of common stock equivalents. Diluted net loss per common share is computed by dividing the net loss attributable to Xencor by the weighted-average number of common stock equivalents outstanding for the period. Potentially dilutive securities consisting of stock issuable pursuant to outstanding options and restricted stock units (RSUs), and stock issuable pursuant to the 2013 Employee Stock Purchase Plan (ESPP) are not included in the per common share calculation in periods when the inclusion of such shares would have an anti-dilutive effect.

Basic and diluted net loss per common share is computed as follows:
