15. WEIGHTED AVERAGE COMMON SHARES

Basic net income per share is calculated by dividing net income by the weighted average number of common shares outstanding for the period. Diluted earnings per share is computed by dividing net income by the weighted average number of shares assuming dilution. Dilutive common shares outstanding is computed using the Treasury Stock Method and reflects the additional shares that would be outstanding if dilutive stock options were exercised and restricted stock units were settled for common shares during the period.

The weighted average number of common shares used to compute basic and diluted net income per share for the years ended December 31, 2025, 2024 and 2023 were as follows:

Certain unexercised stock option awards are excluded from our computations of diluted earnings per share, as these shares were out-of-the-money and their effect would have been anti-dilutive. There were no anti-dilutive options for each of the years ended December 31, 2025 and 2024. For the year ended December 31, 2023, fewer than 0.1 million anti-dilutive shares were excluded from the calculation of diluted earnings per share.

In addition to the common stock issued upon the exercise of employee stock options and the vesting of restricted stock units to be settled in stock, we issued less than 0.1 million shares for each of the years ended December 31, 2025, 2024 and 2023, pursuant to our employee stock purchase plan.

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.
