Tower Semiconductor Ltd. reported solid full-year 2025 growth. Revenue rose to $1,566,104 thousand from $1,436,122 thousand in 2024, mainly from higher wafer shipments and the 300mm Agrate, Italy facility running for a full year. Gross profit increased to $363,854 thousand, keeping margins broadly stable.
Net profit attributable to the company grew to $220,470 thousand from $207,864 thousand, with basic earnings per share up to $1.97 from $1.87. Financing income, net, improved to $56,738 thousand while other expense, net, declined to $10,527 thousand, partly offset by higher income tax expense of $21,569 thousand.
Operating cash flow was strong at $395,482 thousand, funding heavy investments in property and equipment of $444,425 thousand. Cash and cash equivalents ended at $235,369 thousand, and total shareholders’ equity increased to $2,904,583 thousand, reflecting retained earnings growth and ongoing stock-based compensation activity.
Tower Semiconductor reported a new partnership with Salience Labs to manufacture photonic integrated circuit–based optical circuit switches for next-generation AI data centers. The collaboration uses Tower’s silicon photonics platforms, including PH18DA with integrated lasers and TPS45PH with low-loss nitride waveguides.
The project is moving from development into a pre-production phase, aiming at product readiness and large-scale deployment in AI data-center networks. Optical circuit switching is positioned as an alternative to electronic packet switching, targeting higher bandwidth, lower latency and reduced power. Dell’Oro Group estimates AI back-end data-center switch spending will exceed $100 billion by 2030.
Tower Semiconductor filed a Form 6-K describing an expanded strategic collaboration with Canadian quantum computing company Xanadu to advance photonic quantum hardware. The partners are co-developing advanced silicon photonics for fault-tolerant quantum computers using Tower’s high-volume silicon photonics platform.
The companies have already completed multiple joint design tapeouts and have co-engineered a custom material stack tailored to Xanadu’s architecture. This stack is intended to support scalability and performance as quantum systems grow in complexity, helping move Xanadu’s hardware from concept to prototype and demonstrator systems in a manufacturable environment.
Current work focuses on optimizing critical components, including ultra-low loss silicon nitride and integrated photodiodes, on Tower’s standard product flows. Tower highlights that this collaboration underscores the breadth of its silicon photonics platform for quantum computing, data centers, telecom, automotive and other advanced applications as the industry progresses toward commercial-scale photonic quantum computing systems.
