NVTS vs POWI: How Navitas Semiconductor and Power Integrations Compare (2026)

Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. NVTS and POWI share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined NVTS and POWI exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Navitas Semiconductor is a power-semiconductor company focused on next-generation materials: gallium nitride (GaN) and silicon carbide (SiC). These wide-bandgap materials switch faster and run more efficiently than traditional silicon power chips, enabling smaller, cooler, and more power-dense designs. Navitas makes money selling GaN power ICs and SiC devices into chargers and adapters for phones and laptops, data center power supplies, solar and energy storage inverters, electric vehicles, and consumer appliances. The company integrates control, drive, and protection circuitry onto its GaN chips, which it markets as a system-level advantage over discrete components. Founded in 2013 and headquartered in Torrance, California, Navitas is a smaller, growth-stage player whose story centers on the AI data center power transition, where rising rack power densities are pushing the industry toward GaN and SiC for higher efficiency.

Power Integrations designs and sells high-voltage analog and mixed-signal integrated circuits used in AC-DC and DC-DC power conversion. Its chips regulate and convert electricity inside phone chargers, appliances, LED lighting, industrial equipment, EV and renewable-energy systems, and data-center power supplies. The company is fabless (it outsources manufacturing), which supports gross margins in the low-to-mid 50 percent range, and it has invested heavily in PowiGaN, its in-house gallium-nitride technology that improves efficiency and shrinks power supplies versus older silicon parts.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• NVTS drivers: AI data center power; GaN and SiC adoption curve.
• POWI drivers: GaN (PowiGaN) adoption; Industrial and data-center demand.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Navitas is small, often unprofitable, and competes against far larger and better-capitalized incumbents (Infineon, onsemi, STMicroelectronics, Texas Instruments) that also sell GaN and SiC. For POWI, power Integrations is cyclical and heavily exposed to consumer electronics, so demand swings and customer inventory corrections can hit revenue sharply.

Pick NVTS if you believe its drivers more; POWI if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the NVTS and POWI guides.

NVTS. Navitas trades as a growth and theme stock rather than on current earnings. Valuation is driven by expectations for GaN and SiC adoption and AI data center power design wins, so the multiple on small current revenue can be high. The financial profile is that of an early-stage semiconductor company investing ahead of scale.

POWI. As of July 2026 the stock trades near the mid-$70s, well off its 52-week high above $90 but far above its low near $31. Revenue is growing in the low single digits off a cyclical trough while GAAP earnings remain depressed, which is why the reported price-to-earnings multiple is extremely high. The valuation reflects expectations for a broader semiconductor upcycle and GaN share gains rather than current earnings.

Headline figures (approximate, early 2026): NVTS shows revenue (ttm) ~$80 million, revenue growth volatile, tied to charger and emerging data center demand, operating margin negative (still investing ahead of scale), net income (ttm) net loss; POWI shows revenue (ttm) ~$447M, q1 2026 revenue ~$108M (up ~3% YoY), non-gaap gross margin ~53.5%, non-gaap eps (q1 2026) ~$0.25.

NVTS and POWI are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
