In a move designed to expand its microcontroller segment, German chipmaker Infineon Technologies is to acquire the automotive ethernet business of US chip designer Marvell Technology in a deal valued at $2.5bn.
Infineon will use existing liquidity and will incur additional debt in order to fund the acquisition – an investment that will strengthen its already strong US footprint – in an all-cash transaction. Infineon has secured acquisition financing from banks.
Once the transaction is complete, Marvell’s automotive ethernet business will become a part of Infineon's automotive division and is expected to generate revenue between $225m and $250m in 2025, with a gross margin of nearly 60 percent.
“The acquisition is a great strategic fit for Infineon as the global number one provider of semiconductor solutions to the automotive industry,” said Jochen Hanebeck, chief executive of Infineon. “We will leverage this highly complementary ethernet technology by combining it with our existing, broad product portfolio to provide our customers with even more comprehensive, leading solutions for software-defined vehicles.”
A global semiconductor leader in power systems and internet of things, Infineon drives decarbonisation and digitalisation with its products and solutions. The company has around 58,000 employees worldwide.
“Marvell has transformed itself into a leading data infrastructure solutions provider, with the data centre end market driving 75 percent of consolidated revenue in the fourth quarter of 2025,” said Matt Murphy, chairman and chief executive of Marvell. “We are immensely proud of the progress we have made in organically growing our automotive ethernet business. We believe this transaction delivers the strongest financial return for Marvell shareholders, given its compelling valuation.”
A key enabling technology for low-latency, high-bandwidth communication, ethernet is crucial for software-defined vehicles, as well as having significant potential in adjacent fields of physical artificial intelligence such as humanoid robots.
The transaction has been approved by Marvell’s board of directors and is expected to close by the end of 2025, subject to customary closing conditions and regulatory approvals.
Mr Murphy concluded: “With Infineon’s optimised platform for automotive applications, we are confident the Automotive Ethernet business is well positioned for continued growth and success.”
