SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized. TOWER SEMICONDUCTOR LTD. Date: November 12, 2025 By: /s/ Nati Somekh Name: Nati Somekh Title: Corporate Secretary Tower Semiconductor Announces New CPO Foundry Technology Available on Tower's Leading Sipho and EIC Optical Platforms Leveraging years of stacked BSI sensor production, Tower's wafer-scale 3D-IC technology unlocks integration of SiPho and EIC processes for emerging applications such as Co-Packaged Optics, including full support by Cadence design tools to the stacked platform technology Migdal Haemek, Israel – November 12, 2025 – Tower Semiconductor (NASDAQ/TASE: TSEM), a leading foundry of high-value analog semiconductor solutions, today announced the expansion of its existing, mature 300mm wafer bonding technology, originally developed and in mass production for stacked BSI image sensors, to enable heterogeneous 3D-IC integration across its industry-leading Silicon Photonics (SiPho) and SiGe BiCMOS processes, including full support by Cadence design tools for the stacked platform technology. The new offering, represents a major step forward in extending wafer-scale 3D integration, requiring simultaneous use of multiple-PDKs, to new domains beyond image sensing, addressing the growing market demand for compact, high-performance systems for data center applications. Building on years of high-volume stacked sensor production on 200mm and 300mm wafers, Tower's wafer bonding technology enables stacking wafers (for example, SiPho (PIC - Photonic IC) and SiGe (EIC - Electronic IC)) to create fully integrated 3D-ICs at the wafer scale. This capability integrates application-specific functions from different process technologies into a single high-density chip, delivering greater functionality and performance in a smaller form factor. This wafer-scale 3D
