Infineon Technologies 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.
The purchase price amounted to US$2.5 billion. Infineon finances the acquisition through a combination of existing liquid funds and additional debt capital. The company has secured the acquisition financing from banks.
With the acquisition, Infineon strengthens its system expertise for software-defined vehicles and further expands its leading position in the field of microcontrollers for automotive applications.
Jochen Hanebeck, CEO of Infineon, said that with an “even more comprehensive” portfolio, they are driving the transformation to software-defined vehicles.
“In addition, the acquisition creates new opportunities in the field of physical AI, such as humanoid robots,” said Hanebeck. “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.
“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.,” said Matt Murphy, chairman and CEO of Marvell.
Ethernet connectivity solutions are vital to software-defined vehicles as they are the backbone of communication for E/E-architectures.
Infineon aims to further expand the newly acquired Ethernet business, by driving innovation and quickly converting it into customer value. The entire Ethernet competence will be bundled in a newly created “Ethernet Solutions” business line within Infineon’s Automotive division.
