Infineon successfully completes acquisition of Marvell’s automotive ethernet business
Infineon has completed the acquisition of Marvell Technology’s Automotive Ethernet business. The transaction agreement was announced in April 2025 and has received all necessary regulatory approvals.
“This transaction significantly reinforces our number one position in automotive semiconductors and strengthens our strategy of profitable growth” said Jochen Hanebeck, CEO of Infineon. “With an even more comprehensive portfolio, we are driving the transformation to software-defined vehicles together with our customers and partners. In addition, the acquisition creates new opportunities in the field of physical AI, such as humanoid robots. We are excited to welcome several hundred highly skilled and motivated employees to the Infineon team and look forward to elevating the use of Ethernet technology to new scales.”
Ethernet is a key enabling technology for low-latency, high-bandwidth communication. It quickly and reliably transfers large amounts of data between components such as microcontrollers, processors and sensors. This makes it crucial for software-defined vehicles and, additionally, it has significant potential in adjacent fields of use such as humanoid robots. The transaction will allow Infineon to provide its customers with even more comprehensive solutions, combining the strengths of Marvell’s Automotive Ethernet portfolio with Infineon’s existing microcontroller and system expertise.
“We’re incredibly proud of what our team has achieved in building a world-class Automotive Ethernet business,” said Matt Murphy, Chairman and CEO of Marvell. “Through relentless innovation and deep partnerships across the automotive industry, they’ve established a leadership position in this critical technology area. Infineon is the right company to take this business to the next level – with the scale, portfolio breadth, and customer reach to unlock its full potential. We’re confident this move will create exciting opportunities for continued growth, and we look forward to seeing the team thrive as part of Infineon.”
Ethernet connectivity solutions are vital to software-defined vehicles as they are the backbone of communication for E/E-architectures. Marvell’s Brightlane Automotive Ethernet portfolio, comprising PHY transceivers, switches, and bridges, delivers high-performance networking capabilities, supporting data rates from 100 Mbps to 10 Gbps, and provides the necessary security and safety features for both current and future in-vehicle networks.
