Earnings per Share
Cintas uses the two-class method to calculate basic and diluted earnings per share as a result of outstanding participating securities in the form of restricted stock awards. See Note 12 entitled Stock-Based Compensation for additional information on restricted stock awards. The following tables set forth the computation of basic and diluted earnings per share using the two-class method for amounts attributable to Cintas' common shares for the fiscal years ended May 31:

For the fiscal years ended May 31, 2025, 2024 and 2023, options granted to purchase 1.0 million, 1.6 million and 4.0 million shares of Cintas common stock, respectively, were excluded from the computation of diluted earnings per share. The exercise prices of these options were greater than the average market price of the common shares (anti-dilutive).

Cintas announced on July 27, 2021, that the Board authorized $1.5 billion share buyback program, which was completed during the fourth quarter of fiscal 2024. On July 26, 2022 and July 23, 2024, Cintas announced that the Board authorized new share buyback programs, each for $1.0 billion. Neither of the outstanding share buyback programs have an expiration date.

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.
