Earnings Per Common Share
The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per common share computations in 2025, 2024 and 2023 (in millions, except per share amounts):
Year Ended December 31,
202520242023
Basic:
Net income attributable to Intercontinental Exchange, Inc.
$3,315 $2,754 $2,368 
Weighted average common shares outstanding

Basic earnings per common share

Diluted:

Effect of dilutive securities - stock options and restricted stock
Diluted weighted average common shares outstanding

Basic earnings per common share is calculated using the weighted average common shares outstanding during the periods.
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. As of December 31, 2025, 2024, and 2023, there were 100,000, 188,000 and 791,000, respectively, outstanding stock options and restricted stock awards excluded from the computation of diluted earnings per common share because had they been included, they would have had an antidilutive effect. As of both December 31, 2025 and 2024, there were 5,000 restricted stock units that were vested but have not been issued included in the computation of diluted earnings per share. Certain figures in the table above may not recalculate due to rounding.

About Earnings Per Share Disclosures

The earnings per share disclosure breaks down the calculation from net income to both basic and diluted EPS, revealing the full impact of a company's capital structure on per-share economics. The reconciliation between basic and diluted share counts exposes how many stock options, RSUs, convertible securities, and warrants are potentially dilutive to existing shareholders.

Key signals: a widening gap between basic and diluted shares indicates growing dilution from equity compensation or convertible instruments. Anti-dilutive securities excluded from the diluted calculation deserve attention — they represent latent dilution that will materialize if the stock price rises. Watch for the effect of share buybacks on per-share metrics: EPS growth driven primarily by repurchases rather than income growth signals weakening fundamentals. Compare year-over-year changes in the diluted share count against equity compensation expense to assess whether management is effectively managing dilution.
