Above the GPU, Below the Rack — The 72 Hours That Confirmed Pass-Through With PMIC Scarcity Through 2027, a Third GPU Repricing, and Wiwynn/Quanta Printing Records Anyway

Last week's TW notes were mostly upstream stories: Samsung and SK Hynix HBM-choked, orders rerouted to Winbond, Nanya, Team Group; foundry and module layers rerated. The three trading days of August 7-8 confirmed the other layers of that same story — GPU card retail prices, PMIC lead times, thermal solutions, server rails, and system OEM EPS — had already completed the pass-through. This wasn't a spot-price mirage; it was structural pricing power printing in every layer above the wafer and below the finished rack.

1) Card vendors just raised prices for a third time this year

The first domino landed August 9 at the retail layer. ASUS and Gigabyte confirmed shipment ASPs on their GPU lineups are being lifted 20%+ — the third GPU price cycle of 2026, following pass-through from NVIDIA and other silicon vendors who raised bundle prices 20-30%. The word "third" in the headline is the signal. Card vendors rarely raise retail three times in a single year without triggering demand destruction; the fact that channel absorption is holding through wave three is the strongest confirmation to date that end-demand elasticity is real, and that channel inventory is thin enough to swallow it.

2) PMIC scarcity is back at pandemic intensity — and runs through 2027

The second domino was Giantec (8081) Chairman Wu Jin-chuan's statement on August 7: PMIC supply shortage has returned to 2020-21 pandemic intensity, with wafer scarcity now expected to persist through 2027. This matters on two axes. First, the upstream constraint is no longer just HBM/DRAM — analog and power-management IC are now joining the queue. Second, for system OEMs downstream, that scarcity is not a risk; it is the justification for pass-through pricing and a three-year lock-in of pricing power. It's the mirror image of Realtek (2379), where FactSet just trimmed 2026 EPS to NT$32.09 (-1.2%) — analog scarcity benefits are not uniform, and only concentrate in categories that can actually digest the pass-through.

3) System OEM prints — records posted *with* rising input costs, not against them

The third and most decisive domino came from system OEMs. Wiwynn (6669) reported H1 2026 after-tax net profit of NT$29.1B (~$908M), EPS NT$156.38 — the highest H1 print in company history. The same board resolution approved $942M in H2 capex. Managements that fear input costs do not double down on capex. This combination — record EPS plus record capex — is the conviction signal.

Quanta (2382) posted July revenue of NT$366.3B (+131% YoY, -4.9% MoM), the second-highest monthly figure in company history. Its August 13 earnings call will hinge on whether AI-server margin fully reflects the pass-through. Chuan-Ho (2059) posted a Q2 gross margin of 87.4% and operating margin of 82.1% — a server rack rail is physical hardware, yet the margin profile now looks like enterprise software IP. Management called it "Taiwan's purest AI+IP name." Aeolus (7711, ASRock's server subsidiary) posted a Q2 record EPS of NT$9.76 (net profit +234% YoY).

4) Every layer between the GPU and the rack lifted together

The distinctive pattern is that every sub-layer between the card and the finished server posted records simultaneously. Auras (3653), Taiwan's leading vapor-chamber thermal maker, hit July revenue of NT$3.21B (+91% YoY, +21% MoM), stock up 27% in five sessions. Songchuan (7788), a relay supplier into VFDs, server PSUs and UPS systems, surged 24% intraday on 80% YoY AI-power-infra revenue growth. Aipu (6531)'s silicon capacitor line rallied 43% in a week to a monthly revenue high of NT$1.104B (+145% YoY). Chih Sheng (2467), a TSMC CoWoS/SoIC supply-chain equipment maker for advanced packaging, hit an all-time high monthly revenue of NT$1.17B. In other words: card retail → PMIC → thermal → power components → rack rails → server integration — every layer captured expanding margin off the same upstream memory cost trigger, rather than absorbing it.

5) TAIEX is selling; earnings are buying

On August 7, TAIEX closed down 0.38% at 44,225.91, slipping below its quarterly moving average on the Iran-Hormuz oil shock. The next day, index futures reclaimed 45,000. With Foxconn (2317) earnings and TSMC (2330) revenue prints due August 10-14, the market's single question this week is whether the foundry-and-assembly middle layer confirms the same pass-through pattern that upstream and downstream have already printed.

Position

Bull: 6669 Wiwynn / 2382 Quanta / 2317 Foxconn — pass-through is hardening into a three-year pricing-power lock-in. Wiwynn's $942M H2 capex commitment is a management-level conviction signal, not a hedge.

Watch: 2308 Delta / 3711 ASE / 8046 Nan Ya PCB — the next layers to be re-rated. Delta's microgrid pivot at its 55th anniversary summit added a fresh angle on the data-center power layer.

Caution: 2379 Realtek / 4961 Fitipower — nominal PMIC/analog beneficiaries, but FactSet trimmed Realtek's 2026 EPS to NT$32.09, and Fitipower explicitly warned of "demand reversal risk" at its investor day. The pass-through trade is concentrated in AI-server-adjacent lanes, not analog broadly.
