LEARN · FUNDAMENTALS

Diluted shares outstanding

Diluted shares include the potential conversion of dilutive securities (options, convertibles, etc.) under the treasury-stock or if-converted methods used in GAAP EPS.

Why it matters

P/E and per-share metrics change if you mix basic vs diluted. One-off share issuances also break naive TTM math.

How RomeWay uses it

Desk P/E prefers diluted EPS from companyfacts. We do not invent a share count to force market-cap when the tag is missing.

FAQ

Basic vs diluted?
Basic uses weighted-average common shares; diluted assumes dilutive securities convert when the GAAP test says they do.
