The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per common share computations for the three months ended March 31, 2025 and 2024 (in millions, except per share amounts):


	Three Months Ended March 31,
	2025		2024
Basic:
Net income attributable to Intercontinental Exchange, Inc.	$	797	$	767
Weighted average common shares outstanding	574		573
Basic earnings per common share	$	1.39	$	1.34
Diluted:
Weighted average common shares outstanding	574		573
Effect of dilutive securities - stock options and restricted stock	3		2
Diluted weighted average common shares outstanding	577		575
Diluted earnings per common share	$	1.38	$	1.33

Basic earnings per common share is calculated using the weighted average common shares outstanding during the period.

Common equivalent shares from stock options and restricted stock awards, calculated using the treasury stock method, are included in the diluted per share calculations unless the effect of their inclusion would be antidilutive. There were no antidilutive stock options outstanding during the three months ended March 31, 2025, and during the three months ended March 31, 2024, there were 0.4 million outstanding stock options excluded from the computation of diluted earnings per common share because to do so would have had an antidilutive effect.
