On May 20, Tower Semiconductor rose 5.57% in regular trading, trading at $266.895/share, with trading volume of $92.21 million.

On the news front, the semiconductor sector rallied broadly, with Marvell Technology up 7.87%, Intel up 6.39%, Advanced Micro Devices up 4.36%, and Micron Technology up 3.57%, forming a sector-wide rebound that lifted individual stocks. Tower Semiconductor had previously surged over 40% on May 13-14 after reporting Q1 adjusted EPS of $0.65 (vs. $0.56 expected), revenue of $413.6 million (up 15% YoY), and announcing a $1.3 billion silicon photonics long-term supply contract for AI data centers with $290 million in customer prepayments received. The stock then pulled back approximately 5.5% on each of the two prior trading days as short-term profit-taking pressure built. With selling pressure largely absorbed, buying interest re-emerged amid the broader sector strength.
