Nissan: Do The New Customer Contracts Really Reduce The Concentration Risk
The new contracts with customers B, C and D improve Nissan's visibility into 2026 to 2028, but they do not really diversify the risk. The largest customer still accounts for 20.63% of sales without a comparable disclosed contract horizon, and the top five customers still made up 65.1% of 2025 revenue.
What This Follow-Up Is Isolating
The main article argued that Nissan entered 2026 with more stable operating results, but not with a truly clean thesis. This follow-up isolates only one question: do the contract extensions announced in late 2025 and early 2026 really reduce concentration risk, or do they simply extend the life of the same dependence on a very small customer base.
The short answer is that the contracts improve visibility, but they do not clean up concentration. In 2025 the top five customers still represented 65.1% of revenue, the top ten represented 83.3%, and the largest customer alone was 20.63% of sales. Customers B, C and D now come with more detailed contract disclosure, but the single biggest customer still does not have a similarly disclosed horizon. So what has improved here is mainly near-term expiry risk for part of the customer base, not the structural dependence itself.
The key number: the three customers with new or expanded contract disclosure, B, C and D, represented 36.88% of 2025 revenue together. That is meaningful. But at the same time the largest customer still represented another 20.63% of revenue without equivalent disclosure, and the company itself says replacing a lost major customer could take 4 to 6 quarters. That is not disappearing concentration. It is concentration with a longer runway.
What Actually Improved
The constructive part here is real. The customer-concentration discussion no longer rests only on long-standing relationships. It now also rests on contracts with clearer time horizons:
| Customer | Share of 2025 revenue | What was disclosed | What it does improve |
|---|---|---|---|
| Customer A | 20.63% | Relationship longer than 22 years, some unique products, and supply agreements on some projects | Strong commercial depth, but no detailed 2026 to 2028 horizon was disclosed |
| Customer B | 18.85% | Two agreements signed on December 29, 2025: one extension through December 31, 2026 for about $24 million in 2026, and another agreement for 2026 to 2027 for about $12 million per year with an option into 2028 | A clearer contract anchor, especially for 2026 |
| Customer C | 10.97% | January 27, 2026 extension through December 31, 2028, with automatic one-year renewal absent breach, and expected supply of about $25 million, $23 million and $27 million in 2026, 2027 and 2028 | The most detailed visibility in the group |
| Customer D | 7.06% | June 30, 2025 expanded and extended agreement for 3 years, with an automatic two-year extension mechanism and expected annual supply of about $18.5 million | Longer duration and a broader commercial frame |
That leads to the first important conclusion. The new contracts do not eliminate concentration, but they do change the shape of the risk. Instead of a major-customer base where a larger share of visibility rests only on relationship history, a larger part of the revenue base now sits inside explicit commercial frameworks with end dates, options, and automatic renewal clauses.
The second conclusion matters just as much. The disclosed dollar figures are not a hard backlog at fixed pricing. Customer B's expected revenue is presented on the basis of current raw-material prices, Customer C's expected supply is presented on the basis of raw-material prices at the signing date, and Customer D's annual figure is also presented on that signing-date raw-material basis. In other words, the agreements improve volume visibility and time horizon, but not a fixed-revenue guarantee detached from input costs.
Why This Still Does Not Clean Up Concentration Risk
The core problem is that better contracts are not the same thing as better diversification. The top five customers rose to 65.1% of revenue in 2025 from 63.2% in 2024, and the top ten rose to 83.3% from 81.2%. So even after the company strengthened parts of its contract framework, the actual revenue base did not become more diversified. It remained extremely narrow.
The sharpest point sits with Customer A. This is the group's largest customer, generating NIS 134.5 million of revenue in 2025 and accounting for 20.63% of sales. The company describes it as one of the world's two largest wipes manufacturers, and as a relationship that has lasted more than 22 years. That is good news, and for good reason. But from a concentration perspective it is also the exact issue: the biggest customer is still the single largest exposure, yet it does not come with the same contract disclosure now given to customers B, C and D. So the recent extensions reduce risk elsewhere in the list, but they do not solve the main concentration point.
There is also a deeper structural layer. The company explains that its relationships with multinational brands are usually conducted either through multi-year supply agreements that define quantity ranges, prices, and price-adjustment mechanisms, or through continued purchases based on volume forecasts and actual orders. That phrasing matters because it means that even in a long-contract world, part of the economics still depends on forecasts, order flow, and the ability to pass through cost changes. The risk therefore shifts from whether a customer exists to how much of the contract framework is truly firm and how much still lives on commercial execution.
Customer tenure also has to be read correctly. In 2025 about 87.8% of revenue came from customers with relationships longer than 5 years. That is a strong sign of stability and switching friction. But tenure is not diversification. It only says the company knows how to retain customers over time. It does not mean the economic damage from losing one of them becomes smaller. In fact, the company itself says replacing a lost major customer could take 4 to 6 quarters, and it also warns that its low customer dispersion increases exposure to the credit risk of each such customer.
Put differently, the new contracts improve certainty inside concentration, not concentration itself.
What To Measure From Here
The next test is not whether the company can announce another isolated extension. The real test is whether the revenue mix starts to look less dependent on a very small customer group, or whether Nissan simply keeps renewing contracts with the same core base.
The three most important checkpoints are these:
- whether the largest customer eventually gets more explicit contract disclosure as well, or remains the main exposure without a visible annual horizon.
- whether Customer B actually progresses through 2026 under both new agreements, and what happens around the 2028 option and 2027 volume base.
- whether the disclosed dollar values for customers B, C and D translate into stable revenue and gross margin in practice, or whether raw-material and freight dynamics eat away at the apparent certainty.
There is also a clear near-term market reading. The market will probably give Nissan some credit for the simple fact that it signed and extended contracts with several of its major customers, especially with Customer C extended through end-2028 and Customer B now framed more clearly into 2026 to 2028. But if the top-five share stays in the mid-60s in the next filings, that credit is likely to remain partial. The reason is simple: the market can distinguish between better visibility and lower dependence. Those are not the same thing.
Bottom Line
Nissan's new customer contracts are not cosmetic. They give the company better commercial visibility into 2026 to 2028, and they provide clearer contractual support across part of the major-customer base. But they do not clean up concentration risk, because the revenue base is still extremely narrow and the single biggest exposure still sits in one customer that accounts for 20.63% of sales without comparable contract disclosure.
So the more precise conclusion is this: Nissan bought time, not diversification. That matters. But it still does not change the fact that the business depends on a very small group of large customers, and that the economic hit from losing one of them would remain material even after all the extensions already signed.
