Delta Electronics
Taiwanese maker of power supplies, converters and data-center power gear for AI, EVs and industry.
The call
Delta rides the AI power-demand wave with real Nvidia integration and rising margins, but its stock's rich valuation leaves it exposed to any slowdown in hyperscaler spending.
Delta Electronics makes the large power systems that run AI data centers, and it has been doing this for 55 years with its own factories and government certifications that take years to get. It is hard to replace because of those certifications and because it has direct partnerships with Nvidia on new technology, but there are still four other companies doing similar work so Delta is not the only choice. The big risk is simple: if tech companies like Amazon, Google, and Microsoft slow down their spending on new data centers, Delta's sales will drop, and the stock price could fall fast since investors are currently paying a premium price based on the expectation that this spending boom will keep going.
Why
01
AI pressure: None apparent. AI data-center buildouts feed Delta's infrastructure segment rather than threaten it, driving 48% YoY sales growth there. Could AI do the core job? Unlikely.
02
Bigger players: Vertiv Holdings. Vertiv, Schneider Electric, Eaton and ABB already ship competing data-center power gear, splitting a market where five vendors hold ~41-43% combined. Could a giant copy it? Probably.
03
What protects it. Direct Nvidia design-in on 800V HVDC racks, plus certifications, plant capacity and customer relationships built over decades.
What would change this call
Nvidia names a primary 800V HVDC supplier other than Delta before Q1 2027 mass production. Would show Delta losing its direct Nvidia integration edge to a rival.
Huawei Digital Power announces a scale deal with a non-Asian hyperscaler (e.g. Microsoft, Amazon). Would show Huawei breaking into markets Delta currently serves.
Delta's infrastructure segment growth turns negative for two consecutive quarters. Would show hyperscaler capex pullback hitting Delta harder than peers.

Questions people ask
- Is Delta Electronics profitable in 2026?
- Yes. Delta Electronics reported Q1 2026 net profit of NT$20.6 billion, up 101% year over year, on sales of NT$159.4 billion, following FY2025 net profit of NT$60.1 billion, up 70.6% year over year, per its analyst meeting filings.
- Who are Delta Electronics' biggest competitors?
- Delta competes with Schneider Electric, Vertiv, Eaton, and ABB in data-center power; these five vendors collectively hold about 41 to 43% of the global data-center power market as of January 2026, per MarketsandMarkets and Mordor Intelligence research.
- Could AI replace Delta Electronics?
- No. Delta manufactures physical power supplies, thermal systems, and automation hardware, functions untouched by generative AI substitution. Instead AI data-center buildouts are a direct revenue driver, with Delta's infrastructure segment sales up 48% year over year to NT$51.3 billion in Q1 2026.
- Is Delta Electronics involved in any lawsuits?
- Yes. Vicor Corporation filed a patent-infringement suit against Delta Electronics and Delta Americas in January 2026, now stayed pending a related ITC proceeding, according to court dockets filed in the Eastern District of Texas dated February 24, 2026.
- Is Delta Electronics stock overvalued?
- It trades at a forward P/E of roughly 42 to 66 times as of July 20, 2026, per Morningstar, after its market cap roughly doubled from about US$79 billion at end-2025 to about US$150 billion by July 2026, leaving it exposed to any AI capex slowdown.
- Does Delta Electronics supply Nvidia?
- Yes, Delta is a named partner for Nvidia's 800V HVDC data-center architecture; Jensen Huang visited Delta's Computex booth on June 4, 2026, and endorsed 800V as the next-generation AI data-center power standard, though he did not confirm Delta as sole supplier.
