As of September 2025, Infineon Technologies has completed 16 acquisitions, with the highest activity occurring in 2023 (three deals) and 2022 (two deals), reflecting a strategic push to bolster its semiconductor portfolio amid growing demand in automotive, industrial, and connectivity sectors.[88] One pivotal acquisition was the purchase of International Rectifier Corporation in January 2015 for approximately $3 billion, which established Infineon as a leader in power management semiconductors by integrating advanced technologies in high-voltage power MOSFETs and integrated power systems. This move expanded Infineon's capabilities in energy-efficient solutions for automotive and industrial applications, enabling broader market penetration in power conversion and control.[15][89] In 2021, Infineon integrated Cypress Semiconductor, acquired for about $10 billion (with an enterprise value of €9 billion) and closed in April 2020, to enhance its microcontroller and analog technology offerings. The deal significantly strengthened Infineon's position in the Internet of Things (IoT) ecosystem, adding expertise in wireless connectivity, non-volatile memory, and capacitive sensing, while expanding its customer base in consumer and automotive segments. The integration added approximately 6,000 employees to Infineon's workforce and substantially boosted its IoT portfolio, contributing to over 30,000 patents in combined intellectual property.[90][91] A key 2023 transaction was the GaN Systems acquisition in October 2023 for $830 million, which reinforced leadership in gallium nitride-based power solutions suitable for efficient RF amplification in 5G telecommunications infrastructure and high-frequency applications. These deals enhanced Infineon's RF portfolio for 5G base stations and improved strategic fit in emerging wireless markets.[92][93] Most recently, in August 2025, Infineon completed the $2.5 billion acquisition of Marvell Technology's Automotive Ethernet business, acquiring intellectual property, team, and customer contracts to advance vehicle networking solutions. This acquisition positions Infineon to capitalize on the shift toward software-defined vehicles, improving high-speed data connectivity for advanced driver-assistance systems (ADAS) and infotainment, while integrating seamlessly with its existing automotive semiconductor strengths.[94][95] Overall, these major acquisitions have strategically expanded Infineon's technological capabilities and market reach, with integration efforts focusing on synergies in R&D and supply chain optimization to drive innovation in power-efficient and connected systems.[91]Key divestitures
Infineon Technologies has undertaken several key divestitures over the years to streamline its operations, reduce exposure to volatile market segments, and concentrate resources on high-growth areas such as automotive, industrial power, and sensor technologies. These moves have allowed the company to enhance operational efficiency and improve profit margins by exiting low-margin or cyclical businesses. In April 2002, Infineon sold its gallium arsenide (GaAs) semiconductor business to TriQuint Semiconductor for an undisclosed amount, as part of early efforts to refocus on core silicon-based technologies amid a challenging market for compound semiconductors. This divestiture involved transferring production facilities and approximately 150 employees, enabling Infineon to prioritize higher-volume applications in communications and power management.[96][97] A significant restructuring occurred in 2006 when Infineon spun off its Memory Products division into Qimonda AG, an independent entity listed on the New York Stock Exchange. The separation transferred DRAM production assets valued at around €1.4 billion in economic terms, allowing Infineon to divest from the highly cyclical memory market, which was prone to price volatility and overcapacity. This strategic shift improved Infineon's overall margins by an estimated 5 percentage points in subsequent years, as it redirected investments toward more stable power semiconductor segments. Qimonda, however, filed for insolvency in 2009 amid the global financial crisis.[98][99] In 2009, Infineon divested its Wireline Communications (WLC) business to an affiliate of Golden Gate Capital for €250 million ($345 million at the time). The sale, which closed in November, included broadband and voice-over-IP assets serving DSL and fiber-optic applications, and resulted in the formation of Lantiq AG. This transaction was motivated by the need to refinance debt and exit a segment facing intense competition from integrated device manufacturers, thereby sharpening Infineon's focus on wireless and power solutions.[100] More recently, in March 2018, Infineon sold the majority of its Radio Frequency (RF) Power Components business to Cree, Inc. (now Wolfspeed) for €345 million ($375 million). The deal encompassed RF power transistors and amplifiers primarily used in mobile base stations and industrial applications, transferring about 160 employees and related intellectual property. By divesting this unit, Infineon reduced its involvement in commoditized RF markets and reinforced its emphasis on power and sensor systems, aligning with a broader strategy to optimize its portfolio for sustainable growth.[101][102] In June 2025, Infineon completed the sale of its 200 mm fabrication facility in Austin, Texas, to SkyWater Technology for approximately $93 million, marking a partial divestiture of legacy manufacturing assets. This move supports Infineon's ongoing optimization of its production footprint, allowing it to retain design and R&D capabilities in Austin while outsourcing mature node production to specialized foundries.[103][104] In September 2025, Infineon agreed to sell its Bangkok and Nonthaburi manufacturing sites in Thailand to Malaysian Pacific Industries Berhad (MPI) for an undisclosed amount. The transaction, expected to close in early 2026, involves transferring the facilities, equipment, and approximately 1,700 employees, enabling Infineon to streamline its global manufacturing network and focus on advanced technologies while maintaining supply chain partnerships with MPI.[105] Such divestitures have occasionally been balanced by targeted acquisitions in complementary areas, further refining the company's strategic positioning.Financial Performance
