Note 9—Net Income per Common and Common Equivalent Share
The following table shows the amounts used in computing net income per share and the weighted average number of shares of basic and of potentially dilutive common shares outstanding (shares in 000’s):
202520242023
Net income
$8,099 $7,367 $6,292 
Weighted average basic shares
443,985 443,914 443,854 
RSUs818 845 598 
Weighted average diluted shares
444,803 444,759 444,452 
Basic earnings per share is calculated by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is calculated based on the dilutive effect of RSUs using the treasury stock method.

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.
