New York, Feb 1, 2026, 20:18 EST — Market closed
- Tower Semiconductor shares closed Friday at $134.73, trading in a range from $132.80 to $140.46 during the session.
- Chip ETFs plunged heading into the weekend, setting the stage for a tough test when markets open Monday.
- All eyes now shift to Tower’s earnings and outlook set for February 11, the next major event on the calendar.
Tower Semiconductor’s U.S.-listed shares closed Friday just off, dipping 0.1% to $134.73. The stock swung widely during the session but ultimately settled near the day’s low.
This is important going into Monday, as the broader chip sector took a risk-off turn late last week. Tower usually moves with the sector mood, even without new company news. With the next fundamental update near, positioning could change fast.
On Friday, Tower’s stock dipped alongside broader semiconductor indexes, with the iShares Semiconductor ETF (SOXX) sliding roughly 4% and the VanEck Semiconductor ETF (SMH) falling about 3%.
For Tower, the key issue now is whether Friday’s drop was simply the sector trimming exposure ahead of a packed earnings schedule, or the beginning of a deeper slide for smaller foundry stocks.
The company will release its fourth-quarter and full-year 2025 results on Feb. 11. A conference call to go over the figures and first-quarter 2026 guidance is scheduled for that morning, according to a regulatory filing.
“Guidance” refers to management’s forecast for the upcoming quarter. For traders, it often carries more weight than past results, particularly in the semiconductor sector where orders can shift rapidly.
Tower is a contract chipmaker, or foundry, that manufactures chips designed by its clients instead of marketing its own branded processors. Its production facilities are located in the United States, Israel, and Japan, according to its Reuters company profile.
Tower’s filings highlight strong demand across end-markets like industrial, automotive, and infrastructure. They also emphasize process technologies, including silicon photonics and silicon-germanium (SiGe), among others.
One major risk is the sector could slump further on Monday, pulling down high-multiple chip stocks no matter how solid their individual outlooks. Another worry: Tower’s Feb. 11 forecast might fall short, potentially weighing on its shares even if the earnings report is strong.
Tower’s earnings release and call on Feb. 11 is the next big catalyst. Investors want to hear first-quarter guidance, shifts in demand, and how management plans to handle capacity and investments.
