On May 29, Tower Semiconductor fell 5.12% in regular trading, trading at $259.73/share, with trading volume of $140 million.

On the news front, market rumors regarding process parameter deviations at the company's Fab 9 facility during 1.6T silicon photonics chip tape-out have continued to ferment, with some batches reportedly showing below-expectation yields that could affect Q2 delivery schedules. The unresolved speculation has persistently weighed on market sentiment over recent sessions.

Additionally, profit-taking pressure remains elevated. The stock had previously surged to a 52-week high of $302.86, driven by a $1.3 billion silicon photonics supply contract and multiple analyst upgrades — including Wedbush raising its target from $140 to $300 and CITIC Securities assigning a $316 target. The stock has now retreated over 13% from that peak, with accumulated gains continuing to unwind. Notably, the broader semiconductor sector showed mixed-to-positive performance today, with Micron Technology up 5.01% and Broadcom up 3.28%, suggesting Tower's decline is primarily driven by company-specific factors rather than sector-wide weakness.
