The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per common share computations for the nine and three months ended September 30, 2026 and 2025 (in millions, except per share amounts):


	Nine Months Ended September 30,				Three Months Ended September 30,
	2026		2025		2026		2025
Basic:
Net income attributable to Intercontinental Exchange, Inc.	$	3,311	$	2,464	$	940	$	816
Weighted average common shares outstanding	564		573		561		572
Basic earnings per common share	$	5.87	$	4.30	$	1.68	$	1.43
Diluted:
Weighted average common shares outstanding	564		573		561		572
Effect of dilutive securities - stock options and RSUs	2		3		2		2
Diluted weighted average common shares outstanding	566		576		563		574
Diluted earnings per common share	$	5.85	$	4.28	$	1.67	$	1.42

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

Using the treasury stock method, common equivalent shares from stock options and service condition RSUs are included in the computation of diluted earnings per common share unless their inclusion would be antidilutive. Performance condition RSUs and market condition RSUs are treated as contingently issuable shares and are included in diluted earnings per common share only if the applicable performance or market condition would be satisfied if the reporting date were the end of the contingency period and the result would be dilutive.

As of September 30, 2026, an immaterial amount of stock options and RSUs were excluded from the diluted earnings per share calculation as their inclusion would have been antidilutive. As of September 30, 2025, there were 0.1 million antidilutive stock options or RSUs outstanding.
