Tower Semiconductor's operations span multiple facilities across Israel, the United States, Japan, and Italy, enabling it to serve a global customer base with a wide array of semiconductor solutions.

The company generates revenue through the provision of wafer foundry services, which involve the fabrication of semiconductor wafers for various applications. Tower Semiconductor offers a range of process technologies, including CMOS image sensors, embedded flash, advanced analog, RF SOI, power platforms, and mixed-signal technologies. These technologies are utilized in a variety of end markets, such as wired and wireless high-speed communications, consumer applications, automotive, medical, security, and industrial applications. The company's customer base includes fabless semiconductor companies and integrated device manufacturers (IDMs) that require specialized manufacturing services for their semiconductor designs.

• Fab 2: Located in Migdal Haemek, Israel, Fab 2 supports geometries ranging from 0.35 to 0.13-micron, using advanced CMOS technology, including CMOS image sensors, embedded flash, advanced analog, RF SOI, power platforms, and mixed-signal technologies. The facility has an overall clean room area of approximately 100,000 square feet and is a key production site for Tower Semiconductor's specialty process technologies.

• Fab 3: Situated in Newport Beach, California, Fab 3 supports geometries ranging from 0.80 to 0.13-micron. The facility comprises 320,000 square feet, including 120,000 square feet of overall clean room area. Fab 3 is a critical asset for Tower Semiconductor's operations in the United States, providing manufacturing capabilities for a variety of semiconductor products.

• Uozu E Tonami CD and Arai E Fabs: Acquired in 2014, these facilities in Japan support geometries down to 65 nanometer. The fabs are leased under a long-term capital lease with a term until March 2032. The Uozu and Tonami facilities remain operational, while the Arai factory ceased operations in July 2022. These facilities are integral to Tower Semiconductor's manufacturing capabilities in the Asia-Pacific region.

• Fab 9: Located in San Antonio, Texas, Fab 9 supports process geometries ranging from 0.18 to 0.8 micron for the processing of products using CMOS and analog-based technologies. The facility was acquired from Maxim in 2016 and is a key production site for Tower Semiconductor's operations in the United States.

• Fab 10: Established in Agrate, Italy, Fab 10 is a collaborative arrangement with STMicroelectronics (ST). Tower Semiconductor's wholly-owned subsidiary, TSIT, shares the cleanroom space and facility infrastructure with ST, utilizing one-third of the installed capacity for its foundry customers. The comprehensive qualification process for Fab 10 was completed in the fourth quarter of 2024, marking the commencement of volume production and operations managed by ST.

• Fab 11: In September 2023, Tower Semiconductor entered into an agreement with Intel to access a 300mm capacity corridor at Intel's facility in New Mexico, U.S. The corridor is currently in the initial equipment procurement and installation phase and is not yet qualified for production. This strategic partnership aims to enhance Tower Semiconductor's manufacturing capabilities and expand its production capacity.

Tower Semiconductor holds a strong position within the semiconductor foundry industry, particularly in the specialty segment. The company competes with foundries such as GlobalFoundries, Vanguard Semiconductor, DongBu, X-Fab, and Hua Hong Semiconductor. Additionally, it faces competition from pure-play advanced technology node-driven foundry service providers like Taiwan Semiconductor Manufacturing Corporation (TSMC), United Microelectronics Corporation (UMC), and Semiconductor Manufacturing International Corp. (SMIC). Tower Semiconductor's competitive advantages include its advanced specialty analog/mixed-signal technology, research and development capabilities, breadth of process offerings, production quality, technical support, and design and engineering services. The company's ability to operate without infringing upon the proprietary rights of others and its strategic partnerships with technology companies further strengthen its competitive position.

Tower Semiconductor's customer base includes a diverse range of fabless semiconductor companies and IDMs that require specialized manufacturing services for their semiconductor designs. The company's products and services cater to various end markets, such as wired and wireless high-speed communications, consumer applications, automotive, medical, security, and industrial applications. By providing high-quality manufacturing services and advanced process technologies, Tower Semiconductor continues to serve a global customer base and maintain its position as a leading semiconductor foundry.
