GAAP vs Adjusted EPS: Why Two Earnings Numbers?
Published Sep 20, 2026
Companies often report earnings per share twice, once under accounting rules (GAAP) and once adjusted by management; here is why they differ and which to trust.
Earnings per share (EPS) is a company's profit divided by its number of shares. Many companies publish it twice: a GAAP figure and an adjusted (or "non-GAAP") figure. They are often different.
What GAAP means
GAAP stands for Generally Accepted Accounting Principles, the standard rules US companies must follow in their financial statements. GAAP EPS is calculated the same way across companies and is audited each year.
What "adjusted" means
Adjusted EPS starts from GAAP and removes items management considers not part of the normal, ongoing business. Common adjustments:
- Stock-based compensation: shares given to employees as pay. A real cost to shareholders, since it dilutes them, but often excluded.
- Amortization of acquired intangibles: the gradual write-off of the value paid for another company's brands, technology, or customer lists.
- Restructuring charges: severance and other costs of reorganizing.
- One-time gains or losses: selling a business, settling a lawsuit, or writing down an asset.
There is no rulebook for adjusted figures. Each company chooses what to exclude, so the same label means different things at different companies.
Why the gap matters
A small gap usually means the business is simple. A large gap, or a gap that grows every year, deserves attention. If a company excludes "one-time" restructuring costs in five years out of five, they are arguably part of the cost of doing business.
How to check
The SEC requires companies that publish a non-GAAP number to show the closest GAAP number next to it and reconcile the two. Look for a table titled "Reconciliation of GAAP to non-GAAP" in the earnings release. Each line is one adjustment; you can decide which ones you accept.
Beating and missing
When headlines say a company "beat" or "missed" earnings, they usually compare adjusted EPS with analysts' expectations, because analysts forecast on that basis. A beat on adjusted EPS can coexist with a GAAP decline. See reading earnings guidance and beats and misses.
