Wistron's record August drew the shorts and a $1.47 billion share sale
August revenue rose 166 percent and June-quarter profit grew twice as fast as sales. By October 2, Wistron had sold $1.47 billion of stock at a 5.5 percent discount and landed on a TWSE short-interest watch list.

A record month, and a ticket on the short list
Wistron booked NT$460.10 billion of August revenue, up 166.46 percent year on year, its first month above NT$400 billion, on AI-server shipments 1. Eight months of 2026 came to NT$2.51 trillion, up 98.87 percent 1.
The June quarter compounded the same way: net profit up 128 percent to NT$14.83 billion on revenue up 64 percent to NT$895.44 billion, earnings moving at twice the speed of sales 1. AI-server demand still exceeds supply, the company said in August 2.
The tape noticed anyway. The TWSE short-interest weekly for October 2 carries Wistron among five highlighted names; the direction of the change sits behind a paywall, so the listing is a flag, not a verdict 3.
The bear template sits one tier up
The case for shorting an AI assembler already exists, in Hon Hai's income statement, the template The Inference traced on October 7 through Foxconn's record quarter. Gross margin fell a third straight year: 6.30 in FY2023, 6.25 in FY2024, 6.15 in FY2025; Q1 2026 ticked up to 6.18, and the June quarter printed 6.12 4.
Hon Hai's gross margin has fallen three years running and slipped again in the June quarter
Data
| Gross margin | |
|---|---|
| FY2023 | 6.3% |
| FY2024 | 6.25% |
| FY2025 | 6.15% |
| Q1 2026 | 6.18% |
| Q2 2026 | 6.12% |
Every point of the operating-margin gain came from cost cuts, and net margin still fell. The mechanism is the contract: silicon priced by companies that do not compete on price, terms set by a handful of hyperscalers, the assembler keeping the thin remainder 4. Morgan Stanley's 2025 tally of GB200 and GB300 racks puts Hon Hai at 52 percent, Wistron at 21, Quanta at 19 4. Same contract, half the share. No source states the shorts' reasoning; this is the template.
Wistron's June-quarter profit grew twice as fast as sales; Hon Hai's did not
Data
| Value | |
|---|---|
| Wistron net profit | 128% |
| Wistron revenue | 64% |
| Hon Hai revenue | 40.84% |
| Hon Hai net profit | 35% |
Shareholders carry the onshoring
The expansion is paid from the share register. On September 7 Wistron priced $1.47 billion of depositary receipts at $58.88, a 5.5 percent discount that diluted holders 7.29 percent; the stock fell more than 6 percent the next day, and the proceeds go to raw materials in foreign currencies, not plants 25.
The plants keep coming. US approvals cover $150 million for a circuit-board assembly subsidiary and a planned $146 million Texas renovation 6, atop the $700 million Fort Worth plant whose July opening lifted the stock 9.7 percent 78. Taiwan's MIC projects the US at 40 percent of Taiwanese AI-server capacity by 2030, from 23 percent this year, Taiwan's share falling to 30 from 47 6.
The tell is the margin line
Wistron's own gross margin is not in the public record reached for this piece; the net line is the proxy, and it moved the right way 1. Third-quarter results settle the trade: the bull side needs the margin to keep proving out, the short side needs the Hon Hai pattern to repeat.
The instrument is 3231.TT (US OTC: WICOF), last NT$189.50, 8 percent under its NT$206 high, worth NT$602.6 billion 136. Until the margin moves, the record months are somebody else's volume.
