The Short Version
Companies often report 'adjusted' or 'non-GAAP' earnings alongside official GAAP figures, excluding items management considers one-time or non-representative (like restructuring charges or stock-based compensation). These can offer useful insight into core, ongoing performance — but they're also unaudited and chosen by the company itself, so they can be used to present a rosier picture than GAAP numbers would show.
Explain It Like I'm 10
Imagine you tell your parents you got '95% on a test,' but that's after you excluded the 3 questions you got wrong because you say 'those weren't fair questions.' Your OFFICIAL grade (GAAP) might really be 80%, but your 'adjusted' story (non-GAAP) sounds a lot better. Sometimes excluding certain one-time weird stuff really is fair and useful — but you should always ask exactly WHAT got left out and why, before trusting the rosier number.
Step-by-Step Example
- 1 GAAP (official) Net Income: $50,000,000.
- 2 Company excludes a $20,000,000 'one-time restructuring charge' and a $10,000,000 'stock-based compensation' expense.
- 3 Non-GAAP (adjusted) Net Income: $50,000,000 + $20,000,000 + $10,000,000 = $80,000,000 — a much rosier number.
- 4 Question to ask: was that restructuring charge really 'one-time,' or did the company also have one last year, and the year before?
- 5 Stock-based compensation is a real cost to existing shareholders (through dilution), even though it doesn't use actual cash — treating it as if it doesn't matter can be misleading.
Quick Recap
- ✓ Always check what's being excluded and whether those 'one-time' items keep recurring every single quarter.
- ✓ Stock-based compensation is a frequent adjustment — it's a real cost to shareholders (via dilution) even though it isn't a cash expense.
- ✓ When GAAP and non-GAAP earnings diverge significantly and persistently, treat it as a signal to dig deeper, not a footnote to ignore.
