Tower Semiconductor Surges After Q1 Beat and $1.3 Billion Silicon Photonics Deals

Upfront payments from silicon photonics customers give the foundry rare visibility into 2027 revenue.

Overview

  • Tower Semiconductor, which reported results Wednesday, posted first‑quarter revenue of about $414 million and adjusted earnings of $0.65 per share, both above forecasts.
  • The company disclosed $1.3 billion in 2027 silicon photonics supply deals, chips that use light to move data for AI data centers, with $290 million in prepayments to lock in capacity.
  • Customers also committed to larger 2028 orders with additional prepayments due by January 2027.
  • Shares jumped about 17% in U.S. trading to multi‑year highs after the earnings beat and contract announcements.
  • An unresolved March lawsuit from GlobalFoundries over 11 patents remains a risk as Tower scales photonics production for AI and optical networking.
