Lumentum Holdings Inc. announced fiscal fourth-quarter 2026 results exceeding Wall Street expectations, with net revenue reaching $1.01 billion. This represents a significant 109% year-over-year increase, driven primarily by demand from cloud and AI applications.
The company's strong performance was also reflected in its full-year revenue of $3.01 billion. Lumentum designs photonic technologies crucial for AI data centers and telecom networks, recently securing a $2 billion investment from NVIDIA.
For the upcoming first quarter of fiscal 2027, Lumentum has provided guidance forecasting revenue between $1.225 billion and $1.275 billion. This outlook suggests continued momentum in the AI and high-speed data transmission sectors.
Despite reporting an unadjusted net loss of $7.2 billion due to a one-time charge from convertible notes conversion, adjusted measures showed strong profitability. The company ended the quarter with $2.7 billion in cash and investments.
