Is Power Integrations profitable in 2025?

Yes. Power Integrations reported FY2025 net revenue of $443.5M, up 6% year over year, with non-GAAP EPS growing 8% and operating cash flow of $112M, up $30M YoY, ending a multi-year downturn, per its February 6, 2026 earnings call.

Did Power Integrations have layoffs recently?

Yes. On February 1-2, 2026 the board approved a reduction in force cutting roughly 7% of the global workforce (about 60 positions), with $3.5-4.0M in severance charges expected mostly in Q1 2026, framed as cost discipline amid revenue softness.

Who is Power Integrations' biggest competitor in AI data center power?

Infineon Technologies is the key rival. Infineon acquired GaN Systems in October 2023 to move GaN production in-house, and it also sits alongside Power Integrations as a named partner on NVIDIA's 800VDC Kyber data-center power architecture disclosed January 14, 2026.

Could AI replace Power Integrations?

No. Power Integrations sells physical high-voltage power semiconductor chips and IP (PowiGaN, FluxLink) to OEMs for chargers, appliances, industrial and automotive gear. It is a hardware business AI cannot substitute; AI data-center buildout is instead a demand driver, evidenced by its NVIDIA 800VDC collaboration through 2026.

Is Power Integrations a safe company to join right now?

Mixed signals: the company cut about 7% of its global workforce (~60 roles) in February 2026 amid consumer-market softness, but FY2025 revenue still grew 6% to $443.5M, industrial revenue grew 15%, and a new CEO, Jennifer Lloyd, took over in 2025.

Who owns Power Integrations stock?

Power Integrations (NASDAQ: POWI) is publicly traded with no controlling parent. As of February 13, 2026, Vanguard held about 12.2% and BlackRock about 11.5% of shares outstanding, per WSJ company data.

The call

Power Integrations is profitable and growing again, with its data-center upside tied to an unsettled three-way split of NVIDIA sockets against Infineon and Navitas.

Power Integrations designs and sells specialized semiconductor chips that manage power in chargers, appliances, factories, and cars. The company's own patented chip designs and long-standing relationships with manufacturers make it hard to replace in its current business, but it is not impossible: Infineon, a much larger German competitor, is building its own competing chips in-house and has already secured spots alongside Power Integrations on NVIDIA's next-generation data-center chip platform launching around 2027. The real question is whether Power Integrations will win enough of those data-center design wins to grow faster, or whether Infineon and other rivals will squeeze it out and limit the company's upside.

Why

AI pressure: None apparent. AI data centers are a new demand source via NVIDIA's 800VDC design, not a threat that eats Power Integrations' business. Could AI do the core job? Unlikely.

Bigger players: Infineon Technologies. Infineon is vertically integrating GaN production and sits alongside Power Integrations on NVIDIA's 800VDC partner list. Could a giant copy it? Probably.

What protects it. Patented PowiGaN and FluxLink isolation tech plus long-standing design-in relationships across chargers, appliances, and industrial gear.

What would change this call

NVIDIA 800VDC Kyber design-win allocation announced among Power Integrations, Infineon, and Navitas by 2027. Shows whether Power Integrations secures meaningful share of the new data-center architecture or is sidelined.
Power Integrations gross margin in Q2 2026 (due Aug 5, 2026) falls below the guided 54-55% range. Would indicate pricing pressure or share loss in core AC-DC design-in business.
Infineon or Navitas announces a shipping integrated GaN switcher IC targeting Power Integrations' existing charger or appliance sockets. Would show the core moat eroding to a competitor product, not just the data-center growth story.

Key numbers

FY2025 revenue $443.5M, up 6% YoY (2025-12-31)
Q1 2026 revenue $108.3M, up 2.6% YoY (2026-03-31)
Q2 2026 guidance $115-120M, margin 54-55% (2026-05-31)

Named risks

Power Integrations could lose 800VDC Kyber socket share to Infineon or Navitas as full deployment nears 2027. Severity: high
Industry-wide shift to vertically integrated GaN IDM manufacturing (Infineon in-house, ROHM licensing TSMC tech) pressures fabless suppliers like POWI. Severity: medium
Execution risk of February 2026 restructuring and 7% workforce cut under new CEO Jennifer Lloyd. Severity: medium
Consumer end-market softness could offset industrial and data-center growth in coming quarters. Severity: medium
