Meaning and calculation
Is per-share profitability expanding at a rate that matches or exceeds top-line business growth? Tracking growth in diluted earnings per share shows whether earnings expansion translates into tangible per-share progress.
EPS growth (%) = (current comparable EPS ÷ prior comparable EPS − 1) × 100; use only with a meaningful positive prior denominator

A hypothetical worked example
Hypothetical: Increasing diluted EPS from USD 1.60 in the prior year to USD 2.00 in the current year yields year-over-year EPS growth of 25%, calculated as 0.40 divided by 1.60.
What can make this comparison misleading?
Aggressive share repurchases can inflate per-share earnings growth even when underlying net income remains stagnant or operational cash generation declines.
If the prior EPS is zero, percentage growth is undefined. A negative prior EPS can make the usual percentage misleading; report the change in dollars and explain the loss-to-profit transition instead. Repurchases can increase EPS even if total earnings do not rise.
What to record beside the number
