Tower plans an aggregate $920 million in capital expenditures, mainly to expand silicon photonics and silicon germanium capacity and other next‑generation capabilities, while acknowledging uncertainty around tool installation timing and future demand. A strategic restructuring in Japan will transfer full ownership of 300mm Fab 7 to Tower and 200mm Fab 5 to Nuvoton’s Japanese unit, with mutual long‑term supply agreements and a targeted closing of April 1, 2027, subject to customary conditions and approvals.
The report highlights exposure to regional conflicts affecting Israeli operations, customer concentration, cyclical demand—especially for AI‑related wafers—equipment and materials supply risks, and approximately $161 million of consolidated debt as of December 31, 2025. Tower states it does not expect to pay dividends in the foreseeable future, prioritizing growth investments and potential capacity expansion over cash distributions.
Tower Semiconductor and Axiro Semiconductor have introduced high-power, high-efficiency Silicon Germanium (SiGe) radar beamforming integrated circuits that are fabricated in Tower’s U.S. facilities. The chips target secure, domestically sourced U.S. defense radar and satcom systems and are described as ramping to volume production.
The new Ku- and X-band BFICs are designed to improve key metrics such as gain, linearity, output power, efficiency and fast switching, supporting demanding modern radar requirements for U.S. defense primes and radar manufacturers. Tower highlights its established aerospace and defense presence and its SiGe technology as a foundation for scalable, mission-critical defense solutions.

A replay of the teleconference will be available for 90 days, allowing broad access to the discussion of results and outlook.
Tower Semiconductor plans a major expansion of its 300mm manufacturing capacity in Japan as part of a strategic restructuring of its TPSCo joint venture with Nuvoton. Tower will take full ownership of the 300mm Fab 7 through a wholly owned Japanese subsidiary, while Nuvoton’s subsidiary will own the 200mm Fab 5.
The companies will sign mutual long-term supply agreements so existing Tower customers at Fab 5 and Nuvoton customers at Fab 7 continue to receive uninterrupted supply. Subject to customary conditions and regulatory approvals, the transaction is targeted to close on April 1, 2027.
Tower targets combined capacity at its existing 300mm facility in Uozu and an intended adjacent expansion to reach four times current 300mm capacity. The expansion, supported by an option to buy the Fab 7 building and land and contingent METI-backed subsidy for adjacent land, is intended to scale its optical and photonics platforms while keeping the fab cash-from-operations positive during the build-out.
