Delta Electronics
Vertically integrated design + manufacturing of power-conversion and thermal hardware sold B2B to hyperscalers, server ODMs, industrial, telecom, and EV OEM customers; high-mix component + system integrator, increasingly moving up-stack into rack-level power and cooling systems.
Earnings, margins, COGS & capex
FY2025 was a record year: revenue crossed NT$550B for the first time (NT$554.9B, +32%), net income NT$60.1B (+71% from NT$35.2B in FY2024), EPS NT$23.14, with gross margin expanding from ~29.5% (2023) to 34.3%. Momentum accelerated into Q1 2026 - revenue NT$159.4B (+36% YoY), net profit NT$20.55B (+101% YoY), EPS NT$7.91, and record 37% gross / 17.8% operating margins. The re-rating is driven by AI data-center power supplies (~25% of 2025 revenue) and liquid cooling (~9%), both running at full capacity.

rising
COGS structure
Cost of goods dominated by semiconductors (power ICs, GaN/SiC devices, MCUs), magnetics/copper/passives, and thermal materials; margin expansion reflects mix shift toward high-value AI power/cooling and pricing power on scarce high-density PSUs rather than input deflation.
Capex
Not precisely disclosed here; capacity expansion across Taiwan, Thailand, India and the US to meet AI-power and liquid-cooling demand, plus 800V HVDC production ramp for Nvidia shipments beginning Q3 2026.

- Liquid cooling / thermal management systems (CDUs, cold plates) for high-density AI racks
- 800V HVDC power architecture co-developed with Nvidia for ~1.1 MW racks, small-volume shipments starting Q3 2026
- Hyperscaler capex up >60% YoY across the four major cloud CSPs
- EV powertrain and charging infrastructure; industrial automation; renewable/energy-storage infrastructure
Bull & bear
Delta is the picks-and-shovels power/thermal winner of the AI data-center build-out, with record and still-rising margins, a Nvidia-blessed 800V HVDC roadmap, and optionality to expand from server power into facility-level systems.
- AI power (~25%) and liquid cooling (~9%) of revenue are the fastest-growing, highest-margin lines and are supply-constrained, not demand-constrained
- Record 37% gross / 17.8% operating margins with Q2 guided +20-30% QoQ show the mix shift is still early
- 800V HVDC shipments to Nvidia begin Q3 2026 - a new product cycle that could expand both TAM and margins and push Delta into Vertiv's turf
- Hyperscaler capex +60% YoY and a ~30% power/cooling TAM CAGR give a multi-year demand runway
- Net-cash balance sheet, decades of power-electronics IP, and global manufacturing footprint are hard to replicate
The stock discounts near-perfect execution at ~74-83x earnings; any AI-capex air-pocket, margin normalization, or competitive/PSU-supply catch-up would de-rate it sharply.
- Valuation leaves little margin of safety - a P/E in the mid-70s to low-80s versus historical ~20-30x for the name
- Management itself signals limited further gross-margin upside from record levels
- Revenue increasingly hostage to a few hyperscalers and Nvidia's roadmap timing (e.g., an 800V delay)
- Vertiv, Eaton, Schneider and Lite-On are investing hard; commoditization of high-density PSUs would erode pricing
- Strong TWD and Taiwan-concentration add FX and geopolitical tail risk to reported earnings
What it is worth
Peer-multiple / growth-adjusted P/E context, not a formal DCF; market cap ~$162B USD (NT$5.18T) on TWSE:2308.
An AI-capex air-pocket or 800V slip plus competitive/PSU margin normalization triggers a de-rating from the mid-70s/low-80s toward the 30-40x range, a large drawdown even on still-healthy fundamentals given how much is priced in.
Revenue grows ~20-30% into FY2026 on AI power/cooling, margins hold near record but plateau; the stock consolidates its re-rating as earnings grow into the ~74-83x multiple rather than expanding it further.
Sustained AI-capex growth + 800V HVDC ramp keeps revenue compounding 25-35% with elevated margins, and the market holds a premium multiple -> continued upside from ~$162B; bullish sell-side targets imply meaningful further re-rating.
Trades at ~74-83x trailing earnings (P/E TTM ~74 per stockanalysis.com; ~83x normalized per some sources) and ~0.56% dividend yield - a large premium to its historical ~20-30x range, reflecting the AI-power re-rating. Justification rests on record/rising margins, +36% revenue growth, and the 800V HVDC/liquid-cooling TAM; the multiple prices in sustained hypergrowth with little downside cushion. Context only, not a buy/sell call.
SWOT
Strengths
- Multi-decade leadership in power conversion with best-in-class efficiency (92%+ on 800V HVDC), a hard-won engineering moat
- Deep design-in relationship with Nvidia and the major server ODMs; positioned as the rack/server power ('white space') incumbent
- Vertical integration and scale manufacturing across Taiwan/Thailand/India enabling supply during acute AI-power shortages
- Diversified base (automation, EV, infrastructure) cushions any single end-market cycle
Weaknesses
- Valuation-rich: P/E ~74-83x prices in sustained hypergrowth, leaving little room for disappointment
- Customer concentration risk as AI revenue skews toward a handful of hyperscalers and Nvidia's roadmap
- Record margins may be near a ceiling - management flags limited further upside
- Legacy segments (consumer power, some industrial automation) grow slowly and dilute the AI narrative
Opportunities
- 800V HVDC transition (Nvidia/Google early adopters) opens a large new TAM and a path into facility-level power (Vertiv's 'grey space')
- Power + cooling TAM projected ~30% CAGR to ~$172.9B by 2030
- Expansion up the stack into full data-center power+thermal systems, energy storage, and microgrid
- EV powertrain and charging as a second secular growth leg
Threats
- Aggressive competition from Vertiv, Eaton, Schneider in end-to-end data-center systems and from Lite-On in server PSUs
- AI-capex cyclicality - a hyperscaler spending pause would compress the highest-margin revenue
- Geopolitical/Taiwan-concentration risk and FX (strong TWD) pressure on reported results
- Commoditization risk if PSU/thermal supply catches up with demand, eroding pricing power
Moats, dependencies & bottlenecks
Moats
Decades of R&D; 92%+ efficiency on 800V HVDC is a genuine technical lead that customers design around.
Co-development on 800V HVDC and rack power locks Delta into reference designs; re-qualifying a new power vendor is slow.
Ability to actually ship at volume during shortages is itself a moat; multi-country footprint diversifies supply.
Cross-selling and cycle diversification, but legacy segments grow slowly.
Dependencies
Customer/roadmap + co-development partner 800V HVDC and AI-rack power tied to Nvidia's architecture cadence; timing slips or share loss would hurt.
AI power/cooling revenue rides ~60% YoY CSP capex growth; a spending pause hits the highest-margin lines.
GaN/SiC device availability (Infineon, Navitas, onsemi, TI) gates high-efficiency PSU output.
Channel/integration Delta's PSUs and CDUs reach hyperscalers largely through ODM system integration.
Advantages
- First-mover, Nvidia-partnered position on 800V HVDC
- Highest-efficiency power conversion in the server 'white space'
- Ability to ship at scale amid acute AI-power shortages
- Net-cash balance sheet funding capacity expansion without dilution
Weaknesses
- Extreme valuation sensitivity to AI-capex sentiment
- Margins near a self-flagged ceiling
- Concentration in a few hyperscaler/Nvidia relationships
- Slow-growth legacy segments dilute blended growth
Bottlenecks
- GaN/SiC power-semiconductor and high-current magnetics supply for premium PSUs
- Manufacturing/test capacity for liquid-cooling CDUs and 800V HVDC systems during ramp
- Skilled power-electronics engineering talent for the HVDC transition
- Qualification lead-times for new power architectures at hyperscaler customers
