Key Financial Metrics

The filing text does not provide specific financial data, including revenue, profit, cash flow, margins, debt, or liquidity figures. This document is a current report of a material event rather than a financial statement.

Material Changes and Operational Milestones

  • High-Volume Shipments: Tower Semiconductor and NewPhotonics have begun high-volume shipments of the NPG102 PIC products supporting 800G and 1.6T data rates.
  • Technology Platform: The products utilize Tower's PH18DA silicon photonics (SiPho) platform, featuring heterogeneously integrated InP components for monolithic integration of lasers, SOAs, modulators, and detectors.
  • Future Roadmap: Volume shipment of CPX-MSA compliant NPC505 chipsets for 6.4T applications is planned to begin in the first half of 2027 (1H27).
  • Market Application: The chips support OEM solutions for FRO/LRO/LPO and Extra-Dense Packaged Optics (XPO) pluggable transceivers, as well as Near-Packaged Optics (NPO) socket pluggable applications.

Guidance, Outlook, and Management Commentary

Management emphasizes that the collaboration addresses the urgent demand for high-bandwidth, energy-efficient optical interconnects in AI infrastructure. Doron Tal, SVP and GM of NewPhotonics, stated that the partnership translates laser-integrated photonics into a practical choice with volume availability. Dr. Ed Preisler, VP and GM of Tower Semiconductor's RF Business Unit, highlighted this as a milestone in scaling optical connectivity for next-generation AI. The companies plan to showcase these products at ECOC 2026 in Malaga, Spain.
