Segment Reporting SEC Comment Letters: 2026 Guide

Segment Reporting SEC Comment Letters: What the Staff Is Really Looking For

Segment reporting under ASC 280 is one of the SEC Division of Corporation Finance's most persistent comment letter targets. If your company is filing its first ASU 2023-07-compliant annual report, or defending a single-segment conclusion, the staff is almost certainly looking at your disclosures right now.

This guide is for CFOs, controllers, and external reporting teams who want to understand exactly how the staff constructs its segment comments, what documents it requests, and how companies have responded, successfully and otherwise. For background on the comment letter process itself, see The SEC Comment Letter Process: A 2026 Practitioner Walkthrough.

Key takeaway: The SEC staff does not just read your segment footnote. It reads your MD&A, your earnings call transcripts, your press releases, and your Form 8-Ks, then cross-checks all of them against what you disclosed. Contradictions drive comments.

Why Segment Reporting Is a Perennial SEC Comment Letter Target

Segment reporting consistently ranks among the top five areas of SEC staff scrutiny, appearing in PwC's annual analysis of SEC comment letter trends year after year. The staff's focus is not academic. Segment structure determines what financial information investors receive, and the staff treats inadequate or manipulated segment conclusions as a material disclosure failure.

Two structural features make ASC 280 a reliable comment letter generator. First, the standard is management-driven: companies identify segments based on how the chief operating decision maker (CODM) actually reviews the business, which means the staff must evaluate internal management reporting to assess compliance. Second, the aggregation criteria under ASC 280-10-50-11 require both economic similarity and qualitative similarity across five dimensions, and companies routinely over-rely on qualitative arguments without demonstrating similar long-term financial performance.

The volume of segment comments increased further after FASB issued ASU 2023-07 on November 27, 2023. Calendar-year companies were required to include ASU 2023-07 disclosures in their FY2024 annual reports (filed in early 2025), with interim disclosures required beginning Q1 2025. The staff is now actively reviewing those first-year filings.

The Five Most Common Segment Comment Letter Triggers

1. CODM Identification and the Information Actually Reviewed

The staff's first question is almost always: who is the CODM, and what do they actually see?

ASC 280-10-50-1 defines an operating segment as a component that (a) engages in business activities generating revenues and expenses, (b) has operating results regularly reviewed by the CODM to make resource allocation decisions and assess performance, and (c) has discrete financial information available. The staff applies all three criteria rigorously.

When the CODM narrative in a 10-K is vague, the staff asks companies to identify the CODM's title and position, describe the information the CODM regularly reviews, and provide a courtesy copy of the actual CODM reporting package. That last request is the one that changes outcomes. If the package shows the CODM reviewing discrete financial data by product line, geography, or brand at a more granular level than what is disclosed externally, the staff will challenge the segment conclusion.

Under ASU 2023-07, companies must now disclose the CODM's title and position and explain how the CODM uses each reported measure of segment profit or loss. The staff has already flagged companies that provided boilerplate explanations without substantive content, including ACV Auctions and Huntsman Corp., which agreed to add the required disclosure in future filings.

2. Operating Segment Identification and the Single-Segment Trap

Claiming a single reportable segment is one of the most frequently challenged conclusions in SEC comment letters.

The staff's investigative approach follows a consistent pattern:

1. Ask the company to explain its segment identification methodology, citing ASC 280-10-50-1.
2. Request a courtesy copy of the CODM's actual reporting package.
3. Cross-check the package against MD&A, earnings call transcripts, investor presentations, and press releases.

The Hain Celestial Group navigated this successfully in 2012. The staff challenged its single-segment conclusion by requesting a schedule of operating segments, an explanation of whether brands constitute segments, and details on what financial information the CODM receives. Hain Celestial defended its position by demonstrating that discrete financial information was available and reviewed only at the consolidated level, not at the brand level: "We have concluded that since this information is provided and reviewed only on a consolidated basis, we have only one operating segment."

The key is consistency. If your CODM package shows brand-level P&Ls, a single-segment conclusion is very difficult to defend.

In 2025, GXO Logistics and SFL Corporation both received comments challenging their single-segment determinations and provided analysis that satisfied the staff. The pattern is durable: expect the staff to ask.

3. The Aggregation Criteria Are Not a Materiality Test

This is the most misunderstood aspect of ASC 280, and the Brunswick case proves it.

The aggregation criteria under ASC 280-10-50-11 require that operating segments have similar economic characteristics AND be similar in all five qualitative areas: nature of products/services, nature of production processes, type/class of customer, distribution methods, and regulatory environment. These criteria are separate from the 10% quantitative thresholds that determine reportability.

Brunswick Corporation learned this distinction the hard way. After acquiring Navico, Brunswick treated it as a separate operating segment, then concluded it could be aggregated into the Parts and Accessories (P&A) reportable segment on the grounds that Navico represented only 2% of combined revenue of all operating segments in 2021 and 7% in 2022, and 1% of combined segment operating earnings in both years, all below ASC 280's 10% quantitative thresholds.

The SEC staff rejected this rationale. The 10% thresholds determine whether a segment must be separately reported; they are not a safe harbour for aggregation. Aggregation requires meeting the economic similarity and qualitative criteria in ASC 280-10-50-11, regardless of size. Brunswick ultimately changed its segment structure effective January 1, 2023, recasting prior periods, and acknowledged in its response letter: "We also considered our correspondence with the Staff in finalizing our 2023 segment conclusions."

The practical implication: if you are aggregating operating segments that do not meet the economic similarity criteria, size alone will not protect you.

4. Earnings Calls and MD&A as Evidence Against You

The staff reads your earnings call transcripts. This is documented, not theoretical.

In the Urban Outfitters comment letter exchange, the staff noted that the company discussed merchandise markdowns and margin pressure at particular brands on earnings calls and in MD&A, creating a contradiction with its single retail reportable segment disclosure. Urban Outfitters identified six operating segments (Urban Outfitters, Anthropologie, Free People, BHLDN, Terrain, and Wholesale) and aggregated five into one retail segment. BHLDN and Terrain each individually accounted for less than 1% of revenue, gross profit, income, and assets.

The staff's comment cited the brand-level performance discussion in MD&A and on earnings calls as evidence that the CODM was reviewing the business at a more granular level than disclosed. Urban Outfitters responded by providing its CODM package and demonstrating that the brands met the aggregation criteria, ultimately satisfying the staff.

The risk is clear: if your investor relations team discusses segment-level performance in more detail than your footnote discloses, the staff will notice. IR scripts, earnings call talking points, and investor day presentations should be reviewed against your formal segment disclosures before they go public.

PwC's SEC comment letter trends analysis confirms the staff will cross-check public communications for consistency with reported segments and will question inconsistencies. This is now standard practice, not an exception.

5. Inadequate Quantitative and Qualitative Disclosures

The staff also comments on what is missing, not just what is wrong.

Common gaps the staff flags include:

• Segment asset disclosures that are incomplete or inconsistent with how assets are allocated internally.
• Revenue disaggregation that does not align with how management discusses revenue externally.
• Reconciliations of segment profit or loss to consolidated income before taxes that are missing or incorrectly structured. AMC Networks and Guess Inc. both received this comment in 2025 and agreed to provide the required reconciliation in future filings.
• Entity-wide disclosures under ASC 280-10-50-41 through 50-42 (revenues from external customers by country, long-lived assets by country) that are insufficiently granular for companies with significant international operations.

ASU 2023-07: What the Staff Is Commenting on in 2026 Filings

ASU 2023-07 created new disclosure obligations that the staff is actively enforcing in 2025 and 2026 comment letters.

All public entities, including those with a single reportable segment, must now disclose:

1. Significant segment expenses that are regularly provided to the CODM and included in the reported measure of segment profit or loss.
2. An "other segment items" amount (a plug: segment revenue minus significant segment expenses minus segment profit/loss).
3. The title and position of the CODM.
4. An explanation of how the CODM uses each reported measure of segment profit or loss.

Single-segment companies cannot avoid these requirements by arguing they are managed on a consolidated basis. The obligations apply regardless of segment count.

PwC's December 2025 analysis of SEC comment letter trends confirms the staff is scrutinising first-year ASU 2023-07 filings for: whether significant segment expenses are disclosed at an appropriate level of granularity, whether the CODM title and position are correctly identified, and whether the explanation of how the CODM uses segment profit/loss measures is substantive rather than boilerplate.

"Significant segment expenses" is a judgment call. The standard does not define a bright-line threshold. The staff expects companies to identify expense categories that are material to the segment's reported measure of profit or loss and regularly provided to the CODM, then disclose them at a level of granularity that is genuinely informative.

The Non-GAAP Trap: Adjusted Segment Metrics and Regulation G

This is the compliance risk that most companies are not aware of, and the staff is actively enforcing it.

Many companies disclose adjusted EBITDA or similar non-GAAP metrics at the segment level. Under ASU 2023-07, if a company discloses an additional measure of segment profit or loss beyond what ASC 280 already requires, that measure must comply with Regulation G and Item 10(e) of Regulation S-K.

As KPMG's Department of Professional Practice summarised from SEC staff remarks: "The SEC staff's view is that ASU 2023-07 does not require or expressly permit disclosure of specific additional segment performance measures. These additional measures must comply with Regulation G and Item 10(e) of Regulation S-K in that they cannot be misleading measures and the required non-GAAP disclosures must be provided."

For single-segment entities, the staff's position is even more specific: the required performance measure would be consolidated net income, not an adjusted or non-GAAP measure. If your company has historically disclosed only adjusted EBITDA at the segment or consolidated level, this is a direct compliance gap.

The auditor responsibility split adds another layer of complexity:

This means your auditors will review whether an additional segment measure is presented in conformity with ASC 280. They will not opine on whether it complies with Regulation G. That gap sits entirely with management and legal counsel.

On significant segment expenses specifically, the staff has stated: "Although ASC 280 does not require a significant segment expense to be calculated in accordance with US GAAP, the SEC staff expects robust and transparent disclosure of non-GAAP significant segment expenses, including a clear labelling of the expense."

If your company uses non-GAAP cost metrics internally (adjusted cost of revenue, cash operating expenses), and those metrics flow into your significant segment expense disclosures, they must be clearly labelled as non-GAAP.

Building a Defensible CODM Narrative Before the Staff Asks

The best time to document your CODM analysis is before you file, not after you receive a comment letter.

A defensible CODM narrative requires consistency across every document that touches segment structure:

• 10-K business description (Item 1): How you describe the business should align with your segment structure. If you describe five distinct business lines in Item 1, a single-segment conclusion requires careful explanation.
• MD&A (Item 7): Period-over-period performance discussion should not be more granular than your segment footnote. If you quantify revenue and margin by product category in MD&A, the staff will ask why those categories are not operating segments.
• Segment footnote: The CODM's title and position, the information regularly reviewed, and the explanation of how the CODM uses segment profit/loss measures must all be substantive.
• Earnings call scripts and investor presentations: Review these against your segment footnote before publication. Brand-level or geography-level performance commentary that is more granular than your formal disclosures creates comment letter risk.
• CODM reporting package: This is the document the staff will request if it challenges your segment conclusion. It should be consistent with your external disclosures. If it shows more granular financial data than your footnote, you need either a clear explanation of why that data does not constitute discrete financial information for a separate operating segment, or a revised segment structure.

For companies that have recently acquired a business and are integrating it, the risk is heightened. Brunswick's experience with Navico illustrates that the staff monitors management reporting changes disclosed in earnings calls and press releases and will question whether segment disclosures have been updated accordingly. When a management reporting structure changes, ASC 280 requires prior-period segment information to be recast unless it is impracticable.

How to Respond to a Segment Comment Letter

Segment comment letters are iterative. Plan for multiple rounds.

The staff's escalation path typically follows three steps:

1. Ask the company to explain its segment identification methodology.
2. Request a courtesy copy of the CODM's actual reporting package.
3. Challenge aggregation conclusions with reference to specific economic similarity criteria under ASC 280-10-50-11.

Companies that cannot produce a coherent, consistent CODM package face the highest risk of a segment recast. Companies that provide a package inconsistent with their external disclosures face an even harder conversation.

Practical response guidance:

• Respond completely the first time. Incomplete responses invite follow-up comments. If the staff asks for your CODM package, provide it with a clear cover memo explaining how it supports your segment conclusions.
• Request a call with the staff when the issue is genuinely complex. The Hain Celestial exchange included an invitation from the staff to discuss the matter by phone. Taking that offer can resolve factual misunderstandings faster than written correspondence.
• Do not over-commit in your response letter. If you agree to enhance future disclosures, be specific about what you will add. Vague commitments generate follow-up comments.
• Expect six months or more for complex segment threads. The iterative nature of these exchanges means open comment letters on segments can run for multiple rounds over an extended period.

FAQ

Where can I find SEC comment letters on segment reporting? Search EDGAR's full-text search at efts.sec.gov using the filing type CORRESP or UPLOAD and terms like "operating segment" or "CODM." Filter by date range and SIC code to find peer examples. See How Do You Search SEC Comment Letters by Form Type? for a detailed walkthrough.

Does ASU 2023-07 apply to single-segment companies? Yes. All public entities must provide the new disclosures, including the CODM's title and position, significant segment expenses, other segment items, and an explanation of how the CODM uses the reported performance measure. Single-segment companies cannot opt out.

If we disclose adjusted EBITDA by segment, does it need a non-GAAP reconciliation? Yes. The SEC staff's position is that any additional segment performance measure disclosed beyond what ASC 280 requires must comply with Regulation G and Item 10(e) of Regulation S-K, including required reconciliations and non-misleading labelling.

Can we aggregate operating segments that are below the 10% quantitative thresholds? Not automatically. The 10% thresholds determine reportability, not aggregation eligibility. Aggregation requires meeting the economic similarity and qualitative criteria in ASC 280-10-50-11. Brunswick's Navico segment was below the 10% thresholds and the staff still rejected the aggregation.

What triggers a segment comment letter? Common triggers include: a single-segment conclusion where MD&A or earnings calls discuss performance at a more granular level; aggregation of segments with dissimilar economic characteristics; missing or incomplete significant segment expense disclosures under ASU 2023-07; and reconciliation gaps between segment profit/loss and consolidated income before taxes.
