Non-GAAP Financial Measures: SEC Rules, Risks, and Red Flags

Non-GAAP financial measures are company-created performance figures that adjust standard GAAP accounting results by adding or removing specific items management considers unrepresentative. More than 85% of large public companies now report at least one, and the SEC flags non-GAAP issues in roughly 30% of all comment letters it sends to filers. Used carefully, these adjusted numbers can clarify how a business actually operates. Used uncritically, they let management present a flattering picture that the audited financial statements don’t support.

What Qualifies as a Non-GAAP Measure

Federal securities regulations define a non-GAAP financial measure as any numerical measure of historical or future financial performance, financial position, or cash flows that either excludes amounts included in the closest comparable GAAP figure, or includes amounts the GAAP figure leaves out.¹ In plain terms, it’s management saying: here’s what our results look like if you ignore certain items we think distort the picture.

Not every alternative number counts. Measures built entirely from GAAP figures or standard operating statistics fall outside the definition. Revenue per unit, same-store sales growth, and subscriber counts are operating metrics, not non-GAAP measures, because they don’t reclassify anything from the income statement or balance sheet. Figures that GAAP itself requires, or that another government regulator mandates, also don’t count.¹ The distinction matters because the SEC’s disclosure rules only apply to measures that meet the regulatory definition.

The Metrics You’ll See Most Often

EBITDA — earnings before interest, taxes, depreciation, and amortization — is the most widely used non-GAAP figure. It strips out financing costs, tax effects, and non-cash depreciation, leaving a number that roughly approximates cash generated by operations. Investors use it to compare profitability across companies with different capital structures and tax situations. The metric is so entrenched that the SEC built a specific carve-out for it, allowing EBITDA to exclude cash-settled charges that other liquidity measures cannot.²

Adjusted net income starts with reported GAAP net income and removes items management considers non-recurring: legal settlements, restructuring costs, asset write-downs, acquisition expenses. The stated goal is a normalized earnings figure reflecting ongoing profitability. The practical problem is that companies have wide discretion in deciding what qualifies as non-recurring.

Free cash flow begins with cash from operating activities on the GAAP cash flow statement and subtracts capital expenditures. The result shows how much cash the business generates after maintaining its physical assets. Because free cash flow is classified as a liquidity measure rather than a performance measure, the SEC prohibits companies from presenting it on a per-share basis in any filing with the Commission.³

Why Companies Report Adjusted Numbers

Management teams argue that GAAP results sometimes carry so much accounting noise they obscure how the business is really performing. A company that closes a factory and takes a $200 million write-down will report a terrible GAAP quarter even if its core product lines grew strongly. Presenting adjusted figures alongside GAAP, leadership says, separates one-time events from underlying trends.

There’s a legitimate version of this argument. GAAP requires recording stock-based compensation as an expense, depreciation on assets that may remain productive for decades, and amortization of intangible assets from acquisitions that happened years ago. None of those entries represents cash leaving the business today, and together they can make a cash-generative company look marginally profitable on paper.

The skeptical reading is equally valid. Those same adjustments let management present the rosiest possible view of results. When every quarter contains “one-time” charges and adjusted earnings always exceed GAAP earnings, the adjustments stop being supplemental context and start being the company’s preferred version of reality. The regulatory framework exists to keep that tension in check.

The SEC Rules That Apply

Two overlapping sets of rules govern non-GAAP disclosures. Regulation G covers any public disclosure of a non-GAAP measure, including earnings calls, press releases, investor presentations, and interviews. Item 10(e) of Regulation S-K layers stricter requirements on top for formal SEC filings like 10-K annual reports and 10-Q quarterly statements.

Regulation G Baseline Requirements

Whenever a company publicly releases material information containing a non-GAAP measure, two core requirements apply. First, the company must present the closest comparable GAAP measure alongside the non-GAAP figure. Second, it must provide a quantitative reconciliation showing exactly how it got from the GAAP number to the adjusted number.⁴ That reconciliation is the single most useful tool you have for evaluating a non-GAAP metric, because it forces the company to itemize every adjustment.

Regulation G also contains a broad anti-fraud provision: a company cannot release a non-GAAP measure that, together with its accompanying information, contains a material misstatement or omits something necessary to make the presentation not misleading.⁴ Most SEC enforcement actions in this area originate here.

Item 10(e) for Formal Filings

Inside formal SEC filings, more rules apply. The company must present the comparable GAAP measure with equal or greater prominence, so the GAAP number cannot be buried in a footnote while the non-GAAP figure gets the headline.² Management must also disclose why it believes the non-GAAP measure provides useful information to investors and describe any additional internal purposes for which it uses the measure.

Item 10(e) imposes outright prohibitions as well. Companies cannot place non-GAAP figures on the face of the financial statements or in their notes. They cannot use titles or descriptions that are the same as, or confusingly similar to, GAAP terminology. And they cannot label something as “non-recurring” and strip it out if the same type of charge is reasonably likely to appear again within two years or already showed up in the prior two years.² That last rule trips up many filers. Restructuring charges, for example, keep showing up at firms that keep calling them non-recurring.

Performance vs. Liquidity

The SEC treats non-GAAP performance measures and non-GAAP liquidity measures differently. A performance measure like adjusted earnings per share reconciles to GAAP earnings per share. A liquidity measure like free cash flow reconciles to GAAP cash from operations.³ Liquidity measures carry an additional restriction: companies cannot exclude charges that required or will require cash settlement, except for EBIT and EBITDA, which get the specific carve-out mentioned earlier.² And liquidity measures cannot be presented on a per-share basis, because the SEC has long worried that per-share cash flow figures get confused with earnings per share.

Adjustments the SEC Treats as Misleading

Beyond the explicit prohibitions, SEC staff has identified categories of adjustments that violate the anti-fraud provision because the results are inherently misleading. The agency has stated that some measures are so misleading no amount of accompanying disclosure will fix them.³ The most common violations:

Excluding normal, recurring operating expenses. Stripping out a routine cost of doing business inflates profitability. The SEC treats any operating expense that occurs repeatedly, even at irregular intervals, as recurring.
Asymmetric adjustments. Removing non-recurring charges from earnings while keeping non-recurring gains from the same period. If a company backs out a legal settlement loss, it must also back out a legal settlement gain.
Changing GAAP recognition principles. Accelerating revenue that GAAP spreads over time, or switching from accrual to cash accounting inside a non-GAAP measure. These adjustments don’t supplement GAAP, they rewrite it. The SEC calls them “individually tailored accounting principles” and treats them as presumptively misleading.
Misleading labels. Calling a non-GAAP metric “net revenue” or “gross profit” when it’s calculated differently from the GAAP line item of the same name. Labels like “pro forma” are also restricted unless the calculation follows Article 11 of Regulation S-X.
Inconsistent presentation. Adjusting out a charge in the current quarter without adjusting for similar charges in prior-period comparisons, creating an illusion of improvement.

These Numbers Are Not Audited

Many investors miss this entirely. The external auditor’s opinion on a company’s financial statements does not cover non-GAAP figures. Because the regulations prohibit non-GAAP measures from appearing in the financial statements or their notes, these figures fall outside the audit’s scope. No independent accountant has verified that management’s adjustments are reasonable, complete, or consistently applied.

Auditors have a limited obligation to read “other information” in documents that contain audited financial statements and consider whether it’s materially inconsistent with the audited numbers. That’s a consistency check, not a verification. If a reconciliation starts from the correct GAAP figure, the auditor’s obligation is largely satisfied even when the adjustments themselves are aggressive. When you rely on a company’s non-GAAP figures, you’re trusting management’s judgment with no independent validation.

Red Flags Worth Watching For

The fundamental problem is that no two companies calculate non-GAAP metrics the same way. Two competitors can both report “Adjusted EBITDA” where one excludes stock-based compensation and the other doesn’t, one strips out acquisition costs and the other keeps them, and neither defines “non-recurring” the same way. Comparing those figures side by side tells you almost nothing about relative profitability.

Stock-based compensation is the single most controversial exclusion. Newly public companies almost universally remove it from adjusted earnings, and roughly half of all public companies continue the practice years after going public. The case for exclusion is that stock compensation involves complex valuation models and doesn’t represent cash leaving the company today. The case against is simpler: if the company didn’t pay employees with stock, it would have to pay them in cash. It’s a real, recurring cost. When a tech company’s non-GAAP earnings look healthy but its GAAP earnings are a fraction of that number, stock compensation is almost always the largest adjustment driving the gap.

Research on public company filings has consistently found that positive non-GAAP adjustments, the ones that push reported earnings above GAAP, far outnumber negative adjustments. Companies overwhelmingly use these figures to look better, not to provide a balanced alternative view. When adjusted earnings exceed GAAP earnings every single quarter for years, the adjustments are closer to marketing material than context.

Several specific patterns deserve concern:

A growing gap between GAAP and non-GAAP earnings. If adjustments get larger every year, the company may be routinely excluding costs that are part of its normal operations.
Vague reconciliation items. The reconciliation schedule should identify each adjustment specifically. Entries like “other adjustments” that lump together large dollar amounts deserve skepticism.
Recurring “non-recurring” charges. If restructuring costs appear in the adjustments quarter after quarter, they aren’t non-recurring. The SEC explicitly prohibits removing charges reasonably likely to recur within two years.²
Non-GAAP figures displayed more prominently than GAAP. If a press release headlines adjusted EPS and you have to scroll to find GAAP EPS, the company is signaling which number it wants you to focus on.
One-direction adjustments. Backing out losses but keeping gains produces a skewed picture. Legitimate non-GAAP reporting applies adjustments symmetrically.

How to Use Non-GAAP Measures Without Being Misled

None of this means you should ignore adjusted figures entirely. Used carefully, they provide information GAAP alone doesn’t capture. The reconciliation schedule is your starting point. Read every line. Each adjustment reflects a management decision about what counts as real earnings, and you should evaluate each one on its own. A fair test: would you accept that exclusion if the company were asking you for a loan?

Compare definitions across companies in the same industry before drawing conclusions about relative profitability or valuation. Many sell-side analysts build their own uniform adjusted metrics precisely because company-reported figures aren’t comparable. If you’re comparing two firms’ adjusted EBITDA, check whether they exclude the same items.

Track the trend in adjustments over time. A company that reported $50 million in non-GAAP adjustments three years ago and now reports $500 million is either growing much more complex or getting more aggressive with its definitions. Either way, the GAAP results deserve more weight than the adjusted figures. The companies whose non-GAAP disclosures earn the most trust are the ones whose adjusted and GAAP results tell roughly the same story.
