On June 17, Tower Semiconductor fell 5.02% in regular trading, trading at $272.5/share, with turnover of $241 million. The decline was primarily driven by broad-based weakness across the semiconductor sector, with no company-specific negative catalysts identified.
The semiconductor sector experienced significant selling pressure during the session. Among peers, Intel fell 6.49%, Marvell Technology declined 5.58%, Advanced Micro Devices dropped 5.09%, Micron Technology lost 4.37%, and NVIDIA slipped 1.53%. The systemic sector rotation weighed heavily on Tower Semiconductor despite the company recently announcing a multi-year indium phosphide epiwafer supply agreement with IQE for data center optical connectivity products, which further strengthens its silicon photonics foundry supply chain positioning.
The company maintains a dominant market share of 70%-85% in the independent silicon photonics foundry segment and over 70% in SiGe processes above 300GHz. Earlier rumors regarding 1.6T silicon photonics chip yields at its Fab 9 facility had been formally dismissed by key customer Zhongji Innolight as fabricated misinformation, and that overhang has largely dissipated.
