- Navitas finished Wednesday 19.3% higher at $30.84, but then slipped in after-hours trading.
- The company put out a new statement linking its 800 VDC power board to NVIDIA’s MGX AI infrastructure ecosystem. That triggered the move.
- Nasdaq opens for regular trading at 9:30 a.m. EDT. June 4 doesn’t appear as a U.S. equity-market holiday for 2026.
Navitas Semiconductor traded higher on Wednesday, gaining 19% to close at $30.84 after news of its involvement with NVIDIA’s AI-infrastructure. But sellers showed up after hours, with Public.com indicating the stock at $28.60, off 7.25% from the close. Another choppy session looks likely on Thursday.
Navitas Semiconductor, based in Torrance, California, said Wednesday it’s showing its 800 V-to-6 V direct-current power board at NVIDIA’s AI Factory MGX Ecosystem Showcase during COMPUTEX 2026 in Taipei. For investors, the main question is whether AI data centers’ rising power needs will let Navitas turn its spot in the supply chain into real revenue.
NVIDIA says 800 VDC, or 800-volt direct current, is a power system designed to reduce energy loss and cut down on cabling in data centers, letting operators fit more compute into the same space. Put simply, 800 VDC moves power to AI server racks with fewer conversion steps that waste electricity.
“Power delivery has become one of the most critical challenges,” Navitas CEO Chris Allexandre said in a statement. Navitas is targeting megawatt-scale AI server racks with its gallium nitride and silicon carbide power chip tech, which is designed to switch electricity at high voltages. Navitas Semiconductor
Nasdaq’s regular hours are 9:30 a.m. to 4 p.m. Eastern. According to the exchange’s 2026 holiday schedule, Juneteenth on June 19 is the next June holiday closure, not June 4.
Navitas is still posting modest sales, even as the stock jumped. First-quarter revenue came in at $8.6 million, up 18% from the previous quarter but well below $14.0 million last year. The company also booked a GAAP operating loss of $27.8 million.
Navitas CFO Tonya Stevens said the company had “strong momentum and growth” in key high-power markets. Navitas is guiding for second-quarter net revenue around $10.0 million, give or take $0.5 million. The guidance is important — the NVIDIA tie-in has to turn into orders, not just interest at the booth. Navitas Semiconductor
Crowded field for power suppliers. NVIDIA includes Navitas, Infineon Technologies, Texas Instruments, and Vertiv in its 800 VDC partner ecosystem. Infineon, after joining NVIDIA’s MGX AI Factory ecosystem last week, said its power-management tech handles conversion from 800 VDC to the lower voltages servers use.
“As a member of NVIDIA’s ecosystem, Infineon is working with NVIDIA to redefine power delivery systems,” said Adam White, president of Infineon’s power and sensor division, in the company’s release. That spells risk for Navitas, which faces rivals also targeting the AI power budget. Infineon
The issue for Navitas is valuation and evidence. Barron’s said the stock jumped about 370% in the last year and is at 137 times estimated next-12-month sales, but analysts still see losses ahead. StockAnalysis lists the average analyst rating at “Hold,” with a 12-month price target much lower than where shares trade now. Barron’s
Tech stocks got hit again as the Nasdaq Composite dropped 0.9% Wednesday. The S&P 500 slipped 0.7%, breaking a nine-day run. Higher oil prices and geopolitical worries weighed on U.S. stocks.
Thursday could see tight, quick trading. Investors are watching to see if buyers hold the line on the post-NVIDIA move at the open or if the stock gives up more ground as traders weigh technical signals against recent sales numbers. After hours moves are often volatile, but more than 112 million shares traded in the latest session. Navitas has shifted from a small-cap name to one of the more watched AI power stocks on Nasdaq.
