3.04 The 2025 gross margin discussion says the margin 'remained constant' and does not mention that inventory write-downs halved
Company F · a US-listed networking equipment company · SEC-style question
In brief
The management's discussion and analysis (MD&A) says cost of revenue rose in line with revenue and gross margin 'remained constant at [n]%'. Note 1 shows inventory write-downs charged to cost of product revenue fell from [amount] in 2024 to [amount] in 2025, a fall of [amount]. The prior-year Form 10-K also reported a [amount] credit to cost of product revenue in 2024 from releasing supplier liabilities, which this Form 10-K's note does not mention; net of that credit the 2024 charge was [amount] and the fall is [amount] (1.44% of pre-tax income), and product margin before these charges fell about [n] percentage points (about 3 points on the gross write-downs). On either basis the flat margin is the net of offsetting movements that the discussion neither names nor quantifies. The company had told the Securities and Exchange Commission (SEC) staff in 2024 that, where it describes two or more factors behind a material change, including offsetting factors, it would quantify each material factor where possible, and it did so for 2024.

What the filing shows, and what the rule requires
| What the filing shows | What the rule requires |
|---|---|
2025 discussion: cost of revenue up [amount] 'driven by a corresponding increase in product and service revenues'; gross margin 'remained constant at [n]%'. No mention of inventory write-downs, which fell by [amount] ([n] to [n]); product margin 60.69% against 60.93%, but 62.42% against 65.47% before write-downs; net of the [amount] 2024 supplier-liability credit reported in the prior-year Form 10-K, the fall is [amount] ([n] to [n]) and product margin before charges 62.42% against 64.21%. | A discussion that names and quantifies the material movements within cost of product revenue: the change in excess and obsolete inventory and supplier-liability charges, and the factors that lowered the underlying product margin (customer mix and pricing, memory and other component costs, tariffs), as the fiscal 2024 discussion did with its [amount] figure. |
The rule
Regulation S-K Item 303(b) (full fiscal years: material changes, including offsetting changes within a line item)
Where the financial statements reflect material changes from period-to-period in one or more line items, including where material changes within a line item offset one another, describe the underlying reasons for these material changes in quantitative and qualitative terms.

Why it applies here. The [amount] fall in write-downs (3.19% of pre-tax income; [amount], or 1.44%, net of the [amount] 2024 credit the fiscal 2024 Form 10-K reported) is not mentioned. The company's own net measure for 2025 is not published, so only management can confirm the size of the net movement.
Why it matters
- Investors see a stable [n]% margin and cannot tell that it depended on lower inventory charges while the underlying product margin fell.
- The staff raised this point on the fiscal 2023 Form 10-K; if the net movement was material, a repeat comment citing the 2024 commitment is the realistic outcome.
How often the SEC staff raises this. In 1,100 SEC staff comment letters on fiscal 2023 and 2024 Forms 10-K, released January 2025 to October 2026, MD&A results of operations drew 239 of the 1,774 numbered comments (13.5%): the third most frequent topic.
The SEC staff has raised this with other companies
The staff asked Autoliv to quantify each factor behind a gross profit change, and came back to Ziff Davis when a later quarterly report did not quantify offsetting factors as its response had proposed.
Exposure
None until management answers; if the net movement was material, a repeat staff comment citing the 2024 undertaking and a revised presentation in future filings
Our workings
the 2025 discussion explains the [amount] increase in cost of revenue only as following revenue and states that gross margin remained constant at [n]%. The table on p.54 gives product revenue of [amounts] and cost of product revenue of [amounts]. Note 1 gives inventory write-downs of [amounts] for 2025, 2024 and 2023, a supplier-liability charge of [amount] for 2023, and says those charges were not material in 2025 and 2024. The same MD&A quantifies the 2024 movement as a [amount] reduction in net excess/obsolete inventory and supplier liability charges. In its [date] reply to SEC staff comments on the fiscal 2023 Form 10-K, the company undertook that where it describes two or more factors behind a material change, including offsetting factors, it would quantify each material factor where possible.
product margin was 60.69% in 2025 and 60.93% in 2024; adding back write-downs gives 62.42% and 65.47%, a fall of 3.05 points; the write-down movement of [amount] is 3.19% of pre-tax income. The company's 2024 'net' figure of [amount] cannot be built from the Note 1 gross charges (they give [amount], or [amount] after the [amount] 2024 credit reported in the prior-year Form 10-K), so the company's net measure includes amounts, presumably releases, that Note 1 does not show.
on the gross Note 1 figures, a material reduction in write-downs offset a material decline in the underlying product margin, which Item 303(b) requires to be described in quantitative and qualitative terms. Because the company's own net measure for 2025 is not published, the size of the net movement can only be confirmed by management; the point is therefore put as a question. Prior-year Form 10-K: Note 1 (p.82) says that in 2024 the company 'recorded a credit of [amount] within cost of product revenue related to such liabilities', while this Form 10-K describes 2024 supplier-liability charges only as not material. Net of that credit the movement is [amount], 1.44% of pre-tax income, and the underlying product-margin decline about [n] points: the question stands on either basis, at a smaller size than the gross figures suggest.
| Measure ($ million) | 2025 | 2024 | Change |
|---|---|---|---|
| Product gross profit | [n] - [n] = [n] | [n] - [n] = [n] | |
| Product gross margin | [n] / [n] = 60.69% | [n] / [n] = 60.93% | [n] - [n] = -[n] points |
| Inventory write-downs (Note 1) | [n] | [n] | [n] - [n] = -[n] |
| Net of the 2024 supplier-liability credit of [n] (prior-year Form 10-K) | [n] | [n] - [n] = [n] | [n] - [n] = -[n] |
| Product margin before charges (gross / net) | ([n] + [n]) / [n] = 62.42% | gross 65.47%; net ([n] + [n]) / [n] = 64.21% | -3.05 points gross; [n] - [n] = -[n] points net |
| Movement against pre-tax income | [n] / [n] = 3.19% gross; [n] / [n] = 1.44% net | ||
| 2024 'net' reduction: company figure vs Note 1 charges | 2023 charges [n] + [n] = [n]; [n] - [n] = [n] | company states [n] | [n] - [n] = [n] not traceable |
Management’s best defense, and our reply
Management would say the gross margin did not change, so there was no material change to explain, and that its net excess and obsolete measure, which includes releases on sale of previously reserved inventory, may have moved far less than the gross write-downs in Note 1. It would add that its 2024 undertaking applied only 'where possible' and to factors it chose to describe, and that the factors affecting margin are listed on p.54-55. However, Item 303(b) expressly covers material changes within a line item that offset one another, and cost of product revenue contains a [amount] fall in write-downs ([amount] net of the 2024 supplier-liability credit) against a larger rise in underlying cost. Only management can say whether the net movement on its own basis was material; that is why the point is a question rather than a finding.
The fix
- Add to the 2025 discussion, for example: 'Gross margin was [n]% in both years. Product margin was 60.7% compared to [n]%: lower net excess/obsolete inventory and supplier liability charges of $[x] million were offset by [customer mix and pricing, memory and component costs, tariffs] of approximately $[y] million.'

Question for the company
What were the net excess and obsolete inventory and supplier-liability charges, on the basis used for the [amount] figure, for 2025 and 2024, and what was their effect on product gross margin? If the net movement was material, which factors offset it so that gross margin was unchanged, and why was neither quantified in the 2025 discussion?

- Result
- 'write-down' hits risk factors (p.17, [n]), the overview on p.53 (possible write-downs after failed customer trials), the critical estimates on p.62 and Note 1 on p.75-76; none discusses the 2025 movement. 'excess/obsolete' hits p.18 (risk factors), p.55 (the list of factors that can affect margin, without amounts) and p.57 (the 2024 discussion). '[n]' hits only Note 1. 'product margin' hits only p.57 (2024 compared to 2023). '[n]' has no hits.
