Shares of Navitas Semiconductor Corporation (NVTS) dropped 7.33% to close at $9.99 on Monday before rebounding 6.21% to $10.61 in after-hours trading. The late recovery came alongside developments surrounding the power semiconductor specialist's newest AI data center technology, developed in partnership with NVIDIA: a 24 kW power delivery board designed to improve efficiency across next-generation computing infrastructure. The move marked a swift turnaround from a session in which the stock finished just below the $10 mark.

Navitas Deepens NVIDIA Collaboration With New Power Board

Navitas Semiconductor announced its latest 800 V-to-12 V power delivery board, designed for NVIDIA's MGX ecosystem. The technology leverages the company's GaNFast components to support advanced power systems across high-performance AI data centers, and it expands Navitas' existing portfolio of power solutions built for demanding computing applications. The GaNFast line is based on gallium nitride, the material at the core of Navitas' push to move beyond conventional silicon.

The new board delivers 24 kW of output while targeting 97% efficiency under full operating loads. It also achieves power density exceeding 2,000 watts per cubic inch, allowing the system to provide substantial power within a compact design suited to modern computing infrastructure and increasingly demanding AI hardware. Efficiency figures of this kind carry operational weight for data centers: power lost during conversion still has to be drawn from the grid and ends up as heat that the facility must manage.

Navitas developed the board around NVIDIA's latest 400 mm by 60 mm form factor. This configuration enables manufacturers to position power components closer to processors, which reduces transmission losses. The design additionally supports higher computing demands without requiring larger power delivery systems.

Single-Stage Architecture Targets Data Center Energy Losses

The technology converts 800 VDC directly into 12 VDC through a single-stage power architecture. This approach removes an intermediate conversion stage commonly found in existing power delivery systems. As a result, operators can reduce energy losses, hardware requirements, and overall system complexity.

At the heart of the board are 16 NV6034 GaNFast transistors within the primary power conversion architecture. The components are arranged in a stacked half-bridge configuration and use Navitas' latest dual-cooled semiconductor packaging. Together, these features support efficient power delivery and improve thermal management during demanding computing operations.

The announcement builds on an earlier collaboration in which Navitas introduced a 20 kW power board that converts 800 VDC into 6 VDC. The latest development extends that prior work with NVIDIA and introduces another option for system designers. Both solutions support the industry's ongoing transition toward higher-voltage power infrastructure for AI computing, where fewer conversion steps between a facility's supply and its processors translate into less energy lost along the way.

Navitas Advances Its AI Infrastructure Strategy

The launch supports Navitas' broader transformation strategy, which centers on advanced power semiconductor technologies. Through this initiative, the company aims to replace traditional silicon components with gallium nitride and silicon carbide alternatives — materials that support higher efficiency and greater power density across demanding electrical applications.

Navitas President and CEO Chris Allexandre identified efficient power delivery as an important requirement for expanding AI infrastructure. He also emphasized the company's work with NVIDIA to simplify power conversion between electrical systems and GPUs. The new technology addresses the growing energy requirements of increasingly powerful computing platforms.

Navitas plans to display the new board at the NVIDIA AI Factory MGX Wall during OCP Global Summit 2026, a major industry gathering for open computing hardware. The presentation will highlight the company's latest power delivery capabilities within NVIDIA's expanding computing ecosystem, and it gives system designers a scheduled opportunity to evaluate the technology within the MGX framework the board was built for.

The after-hours rebound followed a difficult regular trading session as the company continued to advance its AI infrastructure strategy.
