GAAP EPS explained (and why it differs from adjusted EPS)

GAAP EPS is earnings per share calculated under US Generally Accepted Accounting Principles, as reported in SEC filings. Adjusted (non-GAAP) EPS excludes items management deems one-off.

GAAP vs adjusted (non-GAAP) EPS

GAAP EPS is standardized and auditable. Adjusted EPS varies company-to-company because management chooses what to exclude (stock comp, restructuring, amortization, etc.), so it is not comparable across firms.

Basic vs diluted

Basic EPS divides net income by the weighted-average shares outstanding. Diluted EPS also counts options, warrants and convertibles that could become shares — usually the more conservative, widely-cited figure.

Why your data provider may disagree with the filing

Yahoo Finance and Google Finance often show adjusted or later-restated numbers. Aegwah shows as-filed GAAP EPS with a link to the exact filing, so you can always reconcile.
