What Are Non-GAAP Measures?
A non-GAAP measure is any financial metric that starts from audited GAAP figures and then adds back or removes selected items. Common examples include adjusted net income, adjusted EBITDA, free cash flow, and constant-currency revenue growth. Management teams argue these adjusted views better reflect the ongoing economics of the business by excluding noise such as restructuring charges, impairments, acquisition costs, and stock-based compensation.
These measures appear in earnings releases, earnings calls, investor presentations, and MD&A sections rather than in the audited statements themselves. Because there is no standard rulebook for how to calculate them, two companies can label very different calculations with the same name, which is exactly why the SEC polices their presentation.
How the SEC Regulates Them
Regulation G, adopted in 2003 after the dot-com era's creative accounting, requires that any public disclosure of a non-GAAP measure be accompanied by the most directly comparable GAAP measure and a quantitative reconciliation between the two. Item 10(e) of Regulation S-K adds that in SEC filings the GAAP number cannot be given less prominence than the adjusted one.
The SEC also prohibits certain practices outright, such as excluding normal cash operating expenses from a performance measure or presenting a metric in a way that is misleading. Comment letters challenging aggressive non-GAAP presentation are among the most common forms of SEC feedback to issuers, and companies periodically get forced to rework their earnings release formats.
How Analysts Should Use Them
Adjusted figures are genuinely useful when the addbacks are legitimate one-time events. A company that paid a $200 million litigation settlement probably should be evaluated on earnings excluding it. The problems start when adjustments recur every year: a business that reports restructuring charges eight years running is describing a normal cost of operating, not a special item.
A practical discipline is to track the gap between GAAP net income and the company's headline adjusted metric over a multi-year window. A persistently wide or widening spread suggests earnings quality issues. Buy-side analysts and quality of earnings teams frequently rebuild adjusted EBITDA from scratch, accepting some management addbacks and rejecting others, rather than taking the printed figure at face value.
