Earnings per share
Basic earnings per share of Class A common stock is computed by dividing net income or loss attributable to Planet Fitness, Inc. by the weighted-average number of shares of Class A common stock outstanding. Diluted earnings per share of Class A common stock is computed by dividing net income attributable to Planet Fitness, Inc. by the weighted-average number of shares of Class A common stock outstanding adjusted to give effect to potentially dilutive securities.
Shares of the Company’s Class B common stock do not share in the earnings or losses attributable to Planet Fitness, Inc. and are therefore not participating securities. As such, separate presentation of basic and diluted earnings per share of Class B common stock under the two-class method has not been presented. Shares of the Company’s Class B common stock are, however, considered potentially dilutive shares of Class A common stock because shares of Class B common stock, together with the related Holdings Units, are exchangeable into shares of Class A common stock on a one-for-one basis.

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.
