Earnings Per Share
The numerator for both basic and diluted earnings per share is Net income. The denominator for basic earnings per share is the weighted-average shares outstanding during the period.
A reconciliation of basic weighted-average shares outstanding to diluted weighted-average shares outstanding is as follows:
Year Ended December 31,

Effect of dilutive securities(1)

Diluted weighted-average shares outstanding(2)
132.1 135.2 136.3 
(1)The dilutive effect of outstanding stock options, RSUs, PSUs, and Coworker Stock Purchase Plan units is reflected in the diluted weighted-average shares outstanding using the treasury stock method.
(2)There were fewer than 0.3 million potential common shares excluded from diluted weighted-average shares outstanding for the years ended December 31, 2025, 2024, and 2023, respectively. Inclusion of these common shares in diluted weighted average shares outstanding would have had an anti-dilutive effect.

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.
