At a glance. A small, unusually profitable component maker whose AI exposure is already commercial: AI, data center and server is 32% of revenue, and its answer to the 800V transition — high-voltage 277 V and 305 V AC PPTC parts — is shipping to named US accounts including Amazon and Super Micro.
What changed this half
The new headquarters came online. A three-year, roughly NT$800m build in the Xinzhuang industrial park, about 2,430 ping, with heavy automation and smart dashboards. Some process capacity rose 100–200%.
Cost inflation was absorbed, not passed on late. Copper rose about 10%, polymer (PP) 12%, and labour 5%. With a 52% gross margin there was room to reprice, and management said it successfully transferred the increase to customers.
Some demand was pulled forward. Chinese customers ordered ahead of expected passive-component price increases, flattering first-half revenue.
The numbers
| H1 2026 | Value |
|---|---|
| Revenue | NT$321m (~US$10.2m) |
| Gross margin | 52% (Q2 alone 53.7%) |
| Net income | NT$85m (~US$2.7m) |
| EPS | NT$2.28 (~US$0.07) |
Full-year 2026 guidance: revenue about NT$670m, gross margin held above 50%.
A weaker New Taiwan dollar against both the US dollar and renminbi helped the margin.
NVIDIA 800V read-through
Management's framing was direct: data-center rack power architecture has moved from 480 V AC to 800 V HVDC.
Polytronics' response is not an 800 V DC fuse — it did not claim that — but protection at the AC front end feeding the new architecture: 277 V and 305 V AC high-voltage PPTC parts, developed ahead of peers, plus a position in SiC power semiconductors for the new power stage. Named customers include Amazon and Super Micro.
This is a component-level position that is already commercial, which places it ahead of the rack-level names whose 800V products are still scheduled. NVIDIA's architecture is explicit that protection changes at 800 V — fuses on both the high and low side of the DC/DC, with reinforced isolation — so the protection layer has to qualify before the rack ships.
Segments that moved
The four verticals are almost evenly split, which is unusual and reduces cyclicality:
| Vertical | H1 2026 share |
|---|---|
| EV and autonomous driving | 32% |
| AI, data center, server | 32% |
| Automation and robotics | 31% |
| Energy conversion and storage | 4% |
EV runs on vehicle electrification, 48 V mild-hybrid systems and battery management. Polytronics began 48 V high-temperature work 15 years ago, which is how it reached Tesla, Ford, Hyundai and Kia.
Automation is a decade-plus position at ASML, Applied Materials and Bosch, where stability and reliability matter more than price.
The product line has widened from foundational PPTC overcurrent protection — roughly 7% global share, third worldwide — into overvoltage protection (TVS, ESD, MLV, MOV), hybrid parts combining both, and power MOSFETs including PPTC-integrated hybrids.
Guidance
- Full-year revenue about NT$670m with gross margin above 50%.
- Continued focus on the four niche high-growth verticals rather than volume markets.
Management Q&A
Q: Did product prices move in the first half of 2026 because of materials?
A: Management said raw-material costs have risen — metals (mainly copper) by about 10%, polymer materials by 12%, and labour by 5%. Because gross margin is above 50%, a 1% selling-price increase covers about 2% of cost inflation, and price adjustments with Americas and Asia customers have been under way since the start of 2026 and have been accepted. A favourable exchange rate also offset some of the cost pressure.
Q: How is the second-half mix of end applications expected to change?
A: The three main applications — EVs and autonomous driving, AI and data centers, and automation and robotics — are expected to stay at roughly 30% of sales each in the second half. Over the longer term, AI and data centers, especially high-voltage and high-temperature parts, are the main growth engine. Management said the real demand explosion for passives will come from edge computing, such as an AIPC-led replacement cycle.
Q: What is the competitive advantage of high-current products?
A: The core advantage is high power, not merely high current: the strategy is to raise withstand voltage rather than enlarge the part. PPTC voltage capability has been lifted from a conventional 60 V DC to 305 V AC, a five-fold increase in power handling without a larger package, which management calls the company's know-how. That edge is backed by 98 granted patents, with more applications still in process.
