On June 9, Tower Semiconductor fell 5.59% in regular trading, trading at $230.41/share, with trading volume of $126 million.

On the news front, the broader semiconductor sector experienced notable weakness, with peers Marvell Technology down 7.38%, Advanced Micro Devices down 2.48%, Micron Technology down 1.82%, Intel down 1.76%, and NVIDIA down 1.51%, creating broad-based selling pressure that weighed on Tower Semiconductor.

Additionally, the aftermath of earlier market rumors regarding process parameter deviations and subpar batch yields at the company's Fab 9 factory for 1.6T silicon photonics chips continues to suppress sentiment. Although core customer Innolight issued a formal statement classifying the rumor as maliciously fabricated misinformation, and Tower responded that process calibration is standard industry practice with no impact on long-term customer relationships or expansion plans, the residual confidence shock from the incident has not fully dissipated, resonating with sector weakness to intensify the pullback.
