Wiwynn's Sales Doubled but Cash Went Out. What Does the Price Assume?

ANALYSIS · MEMBERS CONTINUE · 5 min free / 14 min full · Data as at 21 Oct 2026

Wiwynn builds the servers and racks that big cloud companies fill their data centres with. Its September revenue was 99.99% higher than a year earlier, and third-quarter revenue set a record. Yet in the first half of 2026 its operations used NT$61.6 billion more cash than they brought in, and since the shares went ex-rights on 2 September they have fallen 28%. On 21 October they closed at NT$1,880. What does the price already assume about the step where the cash is stuck?

In short

• The question: what is Wiwynn's price assuming about its working capital, the gap between paying for parts and being paid for finished racks?
• The answer: Scenario B. At NT$1,880 the market value is about NT$1.05 trillion (ours). That is about 11.7 times one year of third-quarter sales at the first half's profit margin (ours). The price assumes the sales pace and the margin both hold. It does not assume the cash comes back quickly
• Why: inventory reached NT$207.4 billion at 30 June, up from NT$136.3 billion six months earlier. Memory bought on behalf of customers added NT$130.9 billion of other receivables that did not exist at the end of 2025
• The stuck step: the builder's balance sheet. Wiwynn pays for chips, memory and parts before three customers, who make up 99.18% of its receivables, pay for racks. It borrowed and sold bonds to bridge the gap: a US$2 billion convertible in April, a US$1.52 billion bank loan signed on 14 October, and up to NT$15 billion of domestic convertibles still to come

The numbers that matter

Why does Wiwynn sit at the working-capital step?

A cloud company that wants a new AI hall buys three things: the chips, the building and power, and someone to turn the chips into working racks. Wiwynn is the third. It designs and assembles servers and whole racks for a handful of very large buyers. Our hyperscalers layer shows where those buyers sit, and our piece on who makes custom AI chips shows what goes inside the racks.

The business is concentrated. At 30 June three customers made up 99.18% of what Wiwynn was owed by customers. Only one is named in public: in September, Amazon and Wiwynn announced an expansion of Wiwynn's plant in Socorro, Texas, which builds server racks for Amazon. Wiwynn put its investment there at more than US$1.6 billion.

A rack builder makes a thin margin on a very large bill. It has to buy processors, memory, boards and cooling parts first, assemble and test them, ship, and then wait to be paid. When sales double, the parts bill doubles before the cash comes in. That gap is working capital, and in 2026 it became Wiwynn's stuck step.

The first half shows it. Pre-tax profit was NT$36.9 billion. Operating cash was minus NT$61.6 billion. Inventory rose by NT$69.9 billion. A new line, other receivables, rose by NT$130.2 billion, which the accounts describe as mainly materials bought on behalf of third parties. From April, memory for some customers was bought under a procurement agency model: Wiwynn buys the memory, the customer repays it, and the amount stays out of revenue. It lifts the reported margin; it does not lift the cash.

This is not a demand problem. Sales are at records, and our Taiwan Pulse on TSMC's packaging shows the chips upstream are still selling out. The question is who carries the bill between the parts and the payment.

What does NT$1,880 already assume?

A rack builder's price is a bet on three things: how fast sales grow, what margin survives, and whether profit ever becomes cash. Three answers compete:

1. The step tightens. Sales hold at the third quarter's pace, but margins thin as racks carry more pass-through parts and interest bills rise
2. The step holds. Sales hold at the third quarter's pace and the first half's margin holds
3. The step eases. Customers carry more of the parts bill, and profit grows from there

A tip sheet would pick one. Analysis asks which one the price already needs.

Our read, in one line: the price already assumes Scenario B. At NT$1,880 the market pays about NT$1.05 trillion, about 11.7 times a year of third-quarter sales at the first half's net margin (ours). That is not a demanding growth bet. The doubt is about cash: the price assumes Wiwynn can keep funding its customers' parts bill without its margin or its share count giving way. The scenarios and the arithmetic are below.
