At a glance. A strong first half on test demand from AI servers, new energy and EVs — H1 revenue +24%, Q1 EPS NT$1.3. What is shipping is validation kit for today's AI-server power and liquid cooling. What is not shipping is the 800V-adjacent kit: HVDC-related instruments, solid-state transformers, and higher-power PSU modules are in customer evaluation. Management's own condition is that 2027 can stay double-digit if those land.
What changed this half
Orders and mix both improved. H1 revenue was up about 24% year on year; H1 bookings were up 10–15% on 2025, which is the base management is using for the second half. Power supplies, already half of sales, grew 31%; environmental test grew about 30–35%.
Three new products were launched into the high-end catalogue: the ATS-12000 automated test system for AC/DC and server PSUs, the SPS-A switching DC source, and the GDS-2000HD digital storage oscilloscope.
The 2027 growth kicker was named, and conditional. Higher-power PSU modules, solid-state transformers, and HVDC-related test equipment are in evaluation or development with customers. If those programmes are designed in, 2027 operations "have a chance" of double-digit growth. That is a pipeline, not a print.
The numbers
The complete P&L print on this call was Q1; H1 was given as growth rates, not an absolute revenue figure.
| Q1 2026 | Value | Change |
|---|---|---|
| Revenue | NT$820m (~US$26.0m) | +28% YoY |
| Gross margin | 56% | +3pp YoY (from 53%) |
| Net income | — | +90%+ YoY |
| EPS | NT$1.3 (~US$0.04) | — |
| Book value / share | NT$19.37 | Q1-end |
H1 2026: revenue +24% year on year. Regional growth: China +39% (about 20–25% of sales), Japan and Europe/US nearly +20%, Taiwan about +50%. An FX gain of NT$7–8m (~US$0.2m) versus a NT$40m+ loss in H1 2025 helped the comparison.
Gross margin by line in H1: power supplies about 55%; measurement instruments 55–57%; environmental test 40–45%, diluted because some hosts are bought in from a Japanese partner. Solution packages are described as slightly richer than box-instrument sales, with longer cycles.
NVIDIA 800V read-through
GW Instek is a test name, not a rack or PSU shipper. The honest split on this call is between what is already leaving the dock and what is still in a customer's lab.
Shipping today. AI servers, motherboard test, in-vehicle IVI, plus air- and liquid-cooling validation. The instruments named were ASR-6000, PHU, PEL-5000C electronic loads, and DAQ. That is the current high-power / liquid-cooled AI-server generation. Management would not give an AI revenue share — sales go through distributors, and it does not have a clean end-application split.
In evaluation. Higher-power PSU modules, solid-state transformers, and HVDC-related test equipment. Those are the items that actually sit next to NVIDIA's diagram: SST / MV conversion on the way to 800 VDC, and the instruments that have to qualify it. There is no customer, no SOP date, and no revenue. The 2027 double-digit line is conditional on those programmes landing.
Do not upgrade "HVDC test gear in evaluation" into an 800 V product. The company is not on NVIDIA's list, and this half's growth is conventional AI-server and cooling validation, plus China/Taiwan restocking of power products.
Segments that moved
H1 2026 product share as disclosed (does not sum to 100%; the residual was not given):
| Line | H1 2026 share | Notes |
|---|---|---|
| Power products | 50% | +31% YoY; ~55% GM |
| Measurement products | 19% | ~55–57% GM |
| Environmental testing | 18% | +30–35% YoY; ~40–45% GM |
Measurement instruments remain 80–90% of the group over a full cycle; environmental test and video security are the rest. The strategic pitch is a shift from selling boxes to selling integrated application solutions, using Prodigit's high-power electronic-load technology and the ASR-6000 / PHU families. AI data centers, new energy and EVs are the three named demand pools. India and Southeast Asia are the named new geographies.
Guidance
- No numbered financial forecast — company policy.
- H1 bookings +10–15% versus 2025; management is optimistic on the second half and will try to keep it no worse than the first half.
- 2027: double-digit growth is possible if the high-power PSU-module, SST and HVDC test programmes are designed in. That is a condition, not a target.
- AI-server customers have long qualification cycles and high reliability bars; management's answer is to keep spending on those accounts rather than to time a SOP.
Management Q&A
Q: H1 2026 production, qualification and shipments for AI and new-energy auto products, and the contribution in 2027?
A: Applications already shipping include AI servers, motherboard test and automotive IVI, which have driven large purchases of the ASR-6000, PHU series, PEL-5000C electronic loads and DAQ units, with wins in air- and liquid-cooling validation as well. Higher-power PSU modules, solid-state transformers and HVDC-related test gear are in customer evaluation or development; if those land, 2027 has a chance of remaining double-digit.
Q: Which regions and product lines drove H1 2026 growth?
A: China had the strongest growth at 39% and is about 20–25% of revenue; Europe/US and Japan also grew at a double-digit rate, with Japan about 10–15% of sales; Taiwan was up nearly 50%. On product lines, power supplies — the largest mix — kept growing, and environmental-test equipment grew 30–35%.
Q: Outlook for the second half of 2026?
A: The company does not give an external financial forecast. First-half orders were up 10–15% versus the same period of 2025, so the second half is still described as optimistic, and the aim is for the second half not to lag the first.
Q: Gross margin by product line in the first half?
A: Power supplies are about 55%. Measurement instruments are about 55–57%. Environmental-test equipment is about 40–45% because some hosts are purchased from a Japanese partner.
Q: Impact of sharp first-half FX moves on gains and losses?
A: Self-checked H1 2026 shows an FX gain of about NT$7–8m. In the same period of 2025, when the New Taiwan dollar rose, there was an FX loss of more than NT$40m.
Q: Progress of the lawsuit with Chroma?
A: The case is in Taiwan's Intellectual Property Court, at the evidence-and-pleadings stage, with outside counsel. Further results will be announced when there are any.
Q: How much does gross margin rise when moving from box sales into solutions?
A: On past experience, solutions carry a slightly higher gross margin than stand-alone instruments. The sales cycle is longer because of custom work, but pricing is better for that reason; the increment depends on the individual deal.
Q: Roughly what share of revenue is AI servers and new energy?
A: Most sales go through distributors, so collecting end-customer application data is difficult. Management said it has no clear revenue-mix figure to give.
