Tower Semiconductor (TSEM) Stock Analysis & Winston Score

Tower Semiconductor is an Israeli company that makes custom chips for other businesses. It specializes in a type of manufacturing called "analog" and "mixed-signal" semiconductors, which are chips that handle real-world signals like light, sound, and radio waves. Its customers include companies in the medical devices, automotive, aerospace, and consumer electronics industries that need specialized chips but don't want to build their own factories. Tower makes money by charging customers to manufacture chips in its fabrication plants, called "fabs," located in Israel, the United States, and Japan. This is called a "foundry" business model — Tower builds what others design. It operates as a mid-sized specialty foundry, competing less directly with giants like TSMC by focusing on niche processes rather than cutting-edge logic chips. The main growth driver is rising demand for analog chips in electric vehicles and medical imaging, while the main risk is customer concentration and the capital-intensive nature of running semiconductor fabs.
