What Are Non-GAAP Measures?

Non-GAAP measures are financial metrics that adjust standard GAAP (Generally Accepted Accounting Principles) figures to exclude or modify certain items. Common examples include adjusted EBITDA, adjusted net income, and free cash flow.

Companies use these measures to provide what they believe is a clearer view of underlying performance. For example, management may exclude one-time charges, stock-based compensation, restructuring costs, or other items they consider non-recurring or not reflective of core operations.

The SEC does not prohibit non-GAAP measures. In fact, it allows them, but with strict conditions around transparency, consistency, and presentation.

Why the SEC Focuses So Heavily on Non-GAAP

Non-GAAP measures are one of the most common sources of SEC comment letters because they directly impact how investors interpret a company's performance. Unlike GAAP metrics, which are standardized and governed by accounting rules, non-GAAP measures involve management judgment.

That judgment introduces risk. The SEC's concern is not that companies use non-GAAP metrics, it is that those metrics could be:

  • Misleading or overly optimistic
  • Inconsistently calculated across periods
  • Presented more prominently than GAAP results
  • Insufficiently explained or reconciled

Because of this, non-GAAP disclosures are often a focal point in SEC reviews, especially in Form 10-K, 10-Q, earnings releases, and investor presentations.

The Most Common SEC Comment Letter Issues on Non-GAAP

While comment letters vary by company, several recurring issues appear consistently across SEC reviews. These patterns are where most companies run into trouble.

1. Prominence Issues

One of the most frequent SEC comments relates to "prominence." Companies are not allowed to present non-GAAP measures more prominently than the most directly comparable GAAP measures.

Common problems include:

  • Highlighting adjusted EBITDA in headlines without equal GAAP visibility
  • Placing non-GAAP metrics before GAAP metrics in tables or narratives
  • Using larger font, bolding, or emphasis for non-GAAP figures

The SEC's position is clear: GAAP comes first. Non-GAAP is supplemental, not primary.

2. Inadequate Reconciliations

Companies are required to reconcile non-GAAP measures to the most directly comparable GAAP measure. This reconciliation must be clear, quantitative, and easy to follow.

SEC comments often arise when:

  • The reconciliation is missing or incomplete
  • Adjustments are grouped in a way that obscures detail
  • The bridge between GAAP and non-GAAP is difficult to understand

If an investor cannot clearly trace how a company moved from GAAP to non-GAAP, the SEC will likely ask questions.

3. Misleading or Aggressive Adjustments

Another major area of scrutiny is the nature of the adjustments themselves. The SEC often challenges whether certain exclusions are appropriate.

Examples include:

  • Labeling recurring expenses as "non-recurring"
  • Excluding normal operating costs
  • Removing expenses without a clear rationale
  • Using adjustments that appear tailored to improve results

This is where non-GAAP becomes subjective. The SEC's concern is that adjustments should not create a misleading picture of performance.

4. Inconsistent Definitions Over Time

Consistency is critical. Companies are expected to calculate non-GAAP measures in a consistent manner from period to period.

Comment letters often arise when:

  • The definition of a metric changes without explanation
  • New adjustments are introduced selectively
  • Prior periods are not recast for comparability

When definitions shift, it becomes harder for investors to track performance trends, which is exactly what the SEC is trying to prevent.

5. Lack of Clear Explanation

Even when calculations are technically correct, companies can still receive comments if they fail to explain why a non-GAAP measure is useful.

The SEC expects companies to clearly articulate:

  • Why management uses the measure
  • How it helps investors understand performance
  • What limitations the measure has

Without that context, non-GAAP metrics can appear arbitrary or promotional rather than informative.

Why This Keeps Happening

Non-GAAP issues persist not because companies are unaware of the rules, but because of the incentives involved.

Non-GAAP measures allow management to shape the narrative around performance. They can smooth volatility, isolate certain trends, and highlight what management considers the "core" business. But that flexibility also creates tension between storytelling and standardization.

The SEC's role is to ensure that this flexibility does not cross into distortion.

What Comment Letters Reveal About Non-GAAP Usage

Looking across comment letters, a few broader insights emerge:

  • The SEC is less concerned with whether non-GAAP is used and more concerned with how it is used
  • Disclosure clarity is just as important as technical correctness
  • Recurring issues suggest that many companies still push the boundaries of acceptable presentation
  • Patterns often emerge across industries, especially during periods of market stress or shifting accounting standards

In other words, comment letters are not just about fixing isolated issues, they reflect ongoing pressure to keep non-GAAP disclosures aligned with investor expectations.

Why This Matters for Investors and Operators

For investors, non-GAAP comment letters can highlight where a company's performance narrative may be under scrutiny. If the SEC is asking questions about adjustments, definitions, or presentation, it may signal that the company's disclosures require closer examination.

For operators and finance teams, these letters provide a practical roadmap of what to avoid. They show exactly how the SEC evaluates real-world disclosures, not just what the rules say in theory.

A Subtle but Important Insight

One of the more interesting dynamics in non-GAAP comment letters is that they often focus less on hard violations and more on judgment calls.

This suggests that the SEC is not only enforcing rules, but also shaping norms. Over time, repeated comments on similar issues effectively define what "acceptable" non-GAAP disclosure looks like in practice.

That makes trend analysis especially valuable. When the same types of comments appear across multiple companies, it often signals a broader shift in expectations.

Final Thought

Non-GAAP measures are not going away. They are deeply embedded in how companies communicate performance. But they will likely remain one of the most commented-on areas by the SEC.

The reason is structural: non-GAAP sits in the gray area between standardized reporting and management interpretation. That gray area is where both value and risk exist.

For anyone studying SEC comment letters, non-GAAP disclosures are one of the clearest places to observe how regulatory scrutiny, financial storytelling, and investor communication intersect in real time.
