Tower Semiconductor Ltd. Q3 2026 Earnings Recap

Tower’s results and outlook were positive, but the stock’s 2.1% decline was roughly flat by the stated threshold. Revenue grew 33% year over year, and management guided to continued growth into 2027; the call did not identify a specific source of disappointment.

Key Takeaways

• Q3 revenue was $526 million, up 33% from $396 million a year earlier; net profit was $120 million, with a 23% net margin versus 14% a year ago.
• Q4 revenue guidance is $600 million at the midpoint, which management said would bring full-year 2026 revenue to $2 billion, compared with $1.57 billion in 2025.
• Silicon photonics generated approximately $240 million of Q3 revenue. Tower expects year-end capacity to be roughly double the level supporting those shipments, with higher capacity expected to drive a revenue ramp in Q1 and Q2 2027.
• Including its planned 300-mm expansion, Tower targets a 3x increase in silicon photonics start capacity versus the level supporting Q3 shipments. Management said customer commitments extend through 2029 and the expansions are planned to be self-funded.
• Near-package optics prototypes are underway with more than 10 top customers. Tower also announced a substantial capacity agreement with Semtech for its SiGe business.
