Earnings per share
Basic net earnings per share is based on the average number of common shares outstanding during the period. Diluted net earnings per share is based on the average number of shares used for the basic net earnings per share calculation, adjusted for the dilutive effect of RSU, performance shares and deferred compensation equity plan.

The following table sets forth the computation of basic and diluted earnings per share for the years ended September 30, 2025, 2024 and 2023:

For the year ended September 30, 2025, 0.3 million outstanding RSU were anti-dilutive and excluded from net earnings per share calculations. Performance based restricted units of 1.0 million were excluded from the diluted weighted average shares outstanding calculation as the performance targets for those shares had not been achieved as of the end of the current period.

For the year ended September 30, 2024, all outstanding RSU were dilutive and included in the diluted net earnings per share calculations. Performance based restricted stock units of 1.2 million were excluded from the diluted weighted average shares outstanding calculation as the performance targets for those shares had not been achieved as of the end of the period.
For the year ended September 30, 2023, all outstanding RSU were dilutive and included in the diluted net earnings per share calculations. Performance based restricted stock units of 1.2 million were excluded from the diluted weighted average shares outstanding calculation as the performance targets for those shares had not been achieved as of the end of the period.

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.
