Share count change (5y)

Capital returns

The annualized rate of change in diluted shares outstanding over roughly the last five years.

Formula

Share change = (latest diluted shares ÷ shares ~5 years ago)^(1 ÷ years) − 1; negative means the count is shrinking

Why it matters

Your ownership stake is a numerator over a denominator, and this metric is the denominator's trajectory. A share count shrinking 2–3% a year silently adds 2–3% to per-share growth in everything — revenue, earnings, dividends — while a count growing 3% a year means the business must grow that much just for your slice to stand still. It is also the honest net measure of buybacks: repurchases minus all issuance from stock compensation and offerings.

What good looks like

Any sustained negative number is good and earns quality-score credit; −2% to −4% a year reflects a serious, price-disciplined repurchase program. Roughly flat is neutral. Growth above +2% a year triggers our dilution red flag — at that pace shareholders lose over a tenth of their proportional ownership in five years.

Caveats

We adjust historical share counts for stock splits, so the figure reflects real issuance and retirement, not split mechanics. Share issuance for a large, well-priced acquisition can be rational dilution; issuance to fund routine compensation is a recurring cost. Young companies dilute more as a matter of course — the question is whether the rate declines as the business matures.
