Movement Alert｜Tower Semiconductor Rises 5.79% in Regular Trading, Multi-Year InP Epiwafer Supply Agreement with IQE Strengthens Silicon Photonics Supply Chain

On June 15, Tower Semiconductor rose 5.79% in regular trading, trading at 288.75 USD/share, with turnover of approximately $130 million.

On the news front, the company announced a multi-year agreement with IQE for the supply of indium phosphide (InP) epiwafers used in optical connectivity products for data center infrastructure. Indium phosphide features superior electron mobility and optical properties, making it a critical material for manufacturing high-speed fiber-optic communication components. The agreement further solidifies Tower Semiconductor's supply chain positioning in the silicon photonics foundry space by securing stable access to high-quality materials.

Additionally, earlier rumors regarding yield issues with 1.6T silicon photonics chips at the company's Fab 9 facility were formally characterized as maliciously fabricated false information by key customer Zhongji Innolight. Tower also responded that process tuning is standard industry practice and that 800G silicon photonics chip yields have been adjusted to relatively high levels, with market confidence continuing to recover.

Within the Semiconductors sector, the overall sector was broadly stronger. Among individual stocks, Advanced Micro Devices up 8.97%, Micron Technology up 8.25%, Intel up 5.53%, Marvell Technology up 5.03%, NVIDIA up 2.04%.
