Solrom 2025: Customer concentration and backlog quality
Customer A finished 2025 at 52% of revenue and 63.3% of receivables plus contract assets, while backlog barely moved and the contract structure still leaves it with cancellation, freeze, and penalty rights. For Solrom, the question is no longer whether demand exists, but how broad, firm, and company-controlled that demand really is.
The Point Of This Follow-Up
The main article argued that Solrom's defense core improved, but that 2026 still has to prove broader backlog and better cash conversion. This follow-up isolates the link between those two issues: how much of the growth actually opened up beyond one address, and how much certainty the reported backlog really provides.
The short answer up front: the issue here is not weak demand and not a weak customer. Customer A is described as a large, financially strong defense company in Israel. The problem is that exposure to it deepened exactly where the business is most sensitive. It reached 52.0% of revenue, 63.3% of receivables plus contract assets, and a material share of signed backlog, while total backlog barely grew.
That changes the right way to read 2025. When a company leans this heavily on one strong customer, the question is not whether the orders are real. The question is how broad they are, how firm they really are, and how much one counterparty ends up controlling demand, working capital, and forward visibility at the same time.
52% Of Revenue Is Only The Polite Headline
The major-customer disclosure shows a sharp jump. Customer A rose from NIS 27.648 million, or 35.9% of revenue in 2024, to NIS 51.301 million, or 52.0% of revenue in 2025. At the same time, Customer B fell from 11.2% of revenue to only 3.1%. The disclosed major-customer mix did not broaden. It narrowed.
But even 52% is a somewhat flattering number. The same table shows that 17.5% of 2025 revenue came from Customer C through rental income. So inside the operating business itself, Customer A's weight is higher than the consolidated headline suggests. That is easy to miss if the reader stays only with the total-revenue percentage.
The more important part sits on the balance sheet. By year-end 2025, Customer A already represented 63.3% of total receivables and contract assets, versus only 38% a year earlier. Customer B moved in the other direction, down from 22% to 11.3% on that same measure. In other words, concentration did not stay in the income statement. It moved deeper into the working-capital layer.
| Key measure | 2024 | 2025 | Why it matters |
|---|---|---|---|
| Customer A share of revenue | 35.9% | 52.0% | Dependence rose faster than growth |
| Customer B share of revenue | 11.2% | 3.1% | The second pillar weakened rather than strengthened |
| Customer C share of revenue | 15.1% | 17.5% | Part of the top line comes from rent, not from the defense core |
| Customer A share of receivables + contract assets | 38.0% | 63.3% | Exposure is even larger in the cash-on-the-way layer |
| Signed year-end backlog | NIS 55.892 million | NIS 55.676 million | There is no broad backlog expansion offsetting the concentration |
That is already more than a classic anchor-customer story. When the same customer holds almost two thirds of receivables and contract assets, any delay, freeze, or shift in execution pace would affect not only revenue flow but also the speed at which earnings turn into cash.
Why Backlog Quality Is Weaker Than The Number On The Page
The company states explicitly that a material part of its backlog comes from Customer A. It also states that this customer has a cancellation right that does not include significant compensation, even though management says actual cancellations have historically been negligible. That is a material caveat. It means backlog may be signed, but it is not equivalent to a rigid multi-year contract where revenue is largely locked in.
The issue becomes sharper once the contract structure is read in context. Solrom explains that most of its engagements with Customer A are small-scope, low-ticket projects, usually through tender wins and framework agreements. So the concentration does not show up as one obvious mega-program. It is operationally fragmented across many orders, but economically it still returns to the same customer again and again.
The commercial terms themselves are also not neutral. Customer A may cancel any purchase order at its sole discretion, freeze an order or part of it for up to 90 days, and impose penalties of up to 10% of order value for late delivery. If work has already been delivered, the customer pays the agreed price. If an order is canceled before delivery, the company is entitled only to the reasonable direct costs actually incurred up to the cancellation notice. At the same time, new knowledge created through the work belongs exclusively to Customer A, and the company grants it broad use rights over prior knowledge as well.
That is the key distinction. The risk here is not classic credit exposure to a weak customer. The risk is bargaining power and control in the hands of a strong customer precisely when the company is more dependent on it than before.
The number itself does not rescue the story. Signed backlog stood at NIS 55.892 million at the end of 2024, NIS 55.676 million at the end of 2025, and only NIS 59.134 million near the report date in mid-March 2026. So even after a strong defense-demand year, the company did not show a real step-up in signed backlog. What it showed more clearly was deeper reliance on the same customer.
Why Order Headlines Do Not Automatically Mean Backlog Quality
The report itself explains why readers can get misled. The company details a series of material orders during 2025, but in several cases the headline amount is materially larger than the binding order already received in practice. That does not mean demand is weak. It means the distance between a headline and signed backlog can still be wide.
The company's own examples are fairly sharp. In the March 2025 tender worth NIS 4.9 million, the actual order received stood at NIS 1.7 million. In another March 2025 framework worth NIS 10.1 million, the orders received by period-end totaled NIS 8.1 million. In July 2025, the company reported an NIS 18.1 million framework, but the actual order stood at NIS 4.3 million. In December 2025, it reported a NIS 12.1 million win, and by the report date only NIS 1.4 million had been backed by an order.
That is why Solrom's backlog needs to be read carefully. It is not weak in the sense that there is no work. It is weaker in the sense that part of the demand arrives through frameworks, partial call-offs, and repeated order flow rather than through a large, rigid, broadly spread book of work that reduces dependence.
What Needs To Change From Here
For this reading to improve, management does not need a new narrative. It needs three hard changes in the numbers. First, Customer A's share of receivables and contract assets has to start falling, even if it remains a major customer. Second, new orders have to show up from more than one meaningful customer, so Customer B's fade does not remain the 2025 story. Third, signed backlog has to start growing faster than it is being consumed, rather than merely rolling between frameworks, partial exercises, and timing shifts.
The market is likely to focus on this for a simple reason. As long as receivables and contract assets are more concentrated than revenue, the company is effectively financing part of its growth through working capital tied to the same customer. If 2026 delivers more revenue without a decline in that concentration, the concern will not disappear. It will simply migrate from a demand question to a demand-quality question.
Conclusion
Customer A is both an asset and a bottleneck. It gives Solrom scale, pace, and an anchor customer with financial strength. But in 2025 it also became the concentration layer that determines the quality of revenue, the quality of working capital, and the quality of backlog. That is already much more than a footnote about customer dependence.
The important point is that backlog has not yet validated the expansion story. It stayed almost flat, and a material part of it sits against a customer where the company's own disclosure does not describe especially rigid contractual protection. So the 2026 question is not whether Solrom will keep winning orders. It is whether those orders turn into broader signed backlog, lower concentration, and less dependence on the bargaining power of one customer.
What now has to be measured: not only how many orders get announced, but how many convert into hard backlog, how much working capital remains concentrated at Customer A, and whether a real second customer layer finally starts to broaden the business base.
