On July 1, Tower Semiconductor fell 5.11% in pre-market trading, trading at $246.6/share, with turnover of $6.7184 million. The decline was primarily driven by a broad-based selloff across the semiconductor sector.

On the news front, the semiconductor sector faced systemic selling pressure, with major peers declining significantly: Micron Technology down 5.79%, Marvell Technology down 4.67%, Advanced Micro Devices down 3.28%, Intel down 3.09%, and NVIDIA down 2.08%. The sector-wide risk-off sentiment weighed heavily on Tower Semiconductor despite no company-specific negative catalysts. The company had previously announced cumulative shipments exceeding 5 million coherent photonic ICs in partnership with Marvell Technology, and signed a multi-year indium phosphide epitaxial wafer supply agreement with IQE to strengthen its silicon photonics foundry supply chain positioning. Fundamentals remain intact, with the current adjustment largely attributed to sector rotation and systematic pullback pressures.
