Earnings per share
The Company calculates earnings per share in accordance with FASB guidance on earnings per share. Basic and diluted earnings per common share give effect to the change in the number of Company common shares outstanding. The calculation of basic earnings per common share is determined by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the respective periods. The potentially dilutive shares, consisting of outstanding options on common shares, RSUs, common shares to be issued under the ESPP and PUs, have been included in the computation of diluted net earnings per share and the number of weighted average shares outstanding, except where the result would be anti-dilutive.
The number of shares subject to stock awards outstanding but not included in the computation of diluted earnings per common share because their effect was anti-dilutive was 2,289,623, 2,341,015 and 1,119,283 for the years ended December 31, 2023, 2024 and 2025, respectively.

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.
