Shares of Tower Semiconductor jumped 14% to reach $261.14 during Tuesday’s session following the announcement of a substantial Japanese manufacturing expansion supported by a $1 billion subsidy from the Japanese government.

The chipmaker’s stock had already advanced 3% in the prior trading session and has accumulated a 95% gain year-to-date through Monday’s closing bell. Early pre-market activity showed the stock up nearly 19% before moderating.
The comprehensive investment package totals $3 billion, with Japan’s government providing $1 billion through grant programs. The buildout will expand Tower’s 300mm capabilities in Silicon Photonics, Silicon Germanium, and advanced packaging technologies within Japanese borders.
Tower’s Japanese operations run through TPSCo, which encompasses former Panasonic Semiconductor production sites where the company maintains a controlling stake. The expansion facilities are situated in Toyama and Niigata Prefectures.
The rollout encompasses two distinct phases. Phase one focuses on repurposing the Arai location — previously designated as Fab 6 — to handle 300mm Silicon Photonics and advanced packaging operations, while simultaneously ramping production volumes at the Uozu-based Fab 7. The company projects full operational capability for this initial phase by the fourth quarter of 2027.
Revised Financial Projections
Concurrent with the expansion announcement, Tower increased its long-term financial guidance. The semiconductor manufacturer now projects $3.6 billion in revenue and $1.2 billion in net income for 2028. These figures represent a substantial increase from the company’s earlier projections of $2.8 billion in revenue and $750 million in net income — marking significant upward revisions across both metrics.
The second development phase entails constructing a brand-new 300mm production complex adjacent to Fab 7. This additional facility will enhance Silicon Photonics and Silicon Germanium manufacturing capabilities and is anticipated to begin generating earnings contributions in 2029. Implementation of phase two depends on finalizing and executing relevant agreements.
Silicon Photonics and Silicon Germanium semiconductors serve critical roles in optical and wireless networking technologies, markets experiencing accelerated growth driven by data center expansion and artificial intelligence infrastructure deployment.
Tower characterized the expansion as a response to “rapidly growing long-term customer demand” and an initiative to “substantially increase its manufacturing capacity.”
Executive Perspective
Chief Executive Officer Russell Ellwanger expressed that the organization was “honored and appreciative” of Japan’s decision to partner with Tower for advancing what he described as “strategically important technologies.”
Tower further emphasized that the initiative aims to reinforce Japan’s semiconductor industrial base and enhance supply chain security — messaging that resonates with international governmental efforts to boost domestic chip manufacturing capabilities.
The company stated the investment “creates long-term value for both Tower and Japan by establishing advanced domestic manufacturing capabilities.”
Tower’s updated 2028 targets of $3.6 billion in revenue and $1.2 billion in net income are contingent upon successful completion of the expansion’s first phase.
