Navitas Semiconductor stock was flying ahead of the opening bell Tuesday after the company said it was making progress on new power chips to support artificial-intelligence infrastructure designed by Nvidia.
"As Nvidia drives transformation in AI infrastructure, we're proud to support this shift with advanced GaN and SiC power solutions that enable the efficiency, scalability, and reliability required by next-generation data centers," said CEO Chris Allexandre in a statement late Monday.
Navitas stock surged 25% to $12.50 in premarket trading Tuesday. Shares rose 21% Monday, bringing gains so far this year to 179%.
If gains hold, it would bring the stock to a 61% rise over four consecutive days of gains, according to Dow Jones Market Data.
Navitas designs and develops semiconductors using both gallium nitride (GaN) and silicon carbide (SiC) technologies, used in power conversion and charging.
The company said its new devices will enable the 800-volt power Nvidia has said will power its next-generation AI systems. These directly power IT racks, thereby eliminating the need for additional converters, Navitas said.
According to the company the 800 volts direct architecture improves efficiency and scalability, as well as reduces copper usage.
"As the industry moves rapidly toward megawatt-scale AI computing platforms, the need for more efficient, scalable, and reliable power delivery becomes absolutely critical," said Allexandre. "The transition from legacy 54 V architectures to 800 VDC is not just evolutionary, it's transformational."
Earlier this year, Navitas said it was partnering with Nvidia on power infrastructure, sending shares up triple digits.
