Net Loss per Share Attributable to Common Stockholders

13. Net loss per share attributable to common stockholders

As noted above, for periods in which the Company reports a net loss attributable to common stockholders, potentially dilutive securities have been excluded from the computation of diluted net loss per share as their effects would be anti-dilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at period end, from the computation of diluted net loss per share attributable to common stockholders because including them would have had an anti-dilutive effect:


	As of December 31,
	2024		2023		2022
Unvested restricted stock		2,576,855		2,927,152		1,692,819
Outstanding options to purchase common stock		9,605,542		8,276,033		7,548,392
ESPP		73,399		73,415		45,906
Total		12,255,796		11,276,600		9,287,117
