Mobix Labs, Inc. (NASDAQ:MOBX) is one of the fastest-growing semiconductor stocks to buy. On November 19, 2025, the company said it took a strategic minority stake in TalkingHeads Wireless (THW), expanding into high-growth AI infrastructure and deepening a partnership that began in November 2024.

The deal’s rationale is straight from management: AI-era wireless networks need much higher efficiency, and THW’s AI-driven power management, paired with Mobix’s RF engineering, targets significant energy savings at the base-station level. THW is already in advanced prototyping, and the companies frame the combination as an on-ramp to next-gen communications systems where real-time analytics dynamically allocate power and cut waste. Terms weren’t disclosed, but Mobix positions the investment as not just a one-off but a fast entry into the AI infrastructure ecosystem, and an extension of work the two began in 2024 on AI-enabled, energy-efficient base-station tech.

Management also points to market pull: the release pitches AI-driven efficiency in wireless and next-gen communications as a rapidly growing opportunity, with Mobix’s role to commercialize alongside THW rather than reinvent the wheel in-house. The company’s investor site and third-party reprints echo the same thrust and timing, reinforcing the AI infrastructure strategy narrative.

Mobix Labs, Inc. (NASDAQ:MOBX) is a fabless semiconductor and connectivity company focused on high-performance RF, optical, and mixed-signal solutions for communications, defense, and emerging AI infrastructure markets.
