Analysis
Lumentum reported fiscal fourth-quarter net revenue of $1,006.3, up 24.5% sequentially and 109.3% year over year. Growth was broad across reported product types: Components revenue was $649.4 and Systems revenue was $356.9, with Systems posting the faster sequential and year-over-year percentage increases. For fiscal year 2026, total net revenue was $3,014.0, compared with $1,645.0 in fiscal year 2025.
Profitability improved materially on both reported bases. Fourth-quarter GAAP gross margin was 47.4 % and GAAP operating margin (loss) was 27.8 %, compared with 44.2 % and 21.6 % in the prior quarter. Non-GAAP gross margin reached 50.4 % and non-GAAP operating margin reached 36.6 %, each above the prior-quarter and prior-year levels printed in the release. The annual results similarly show expansion in GAAP and non-GAAP gross and operating margins.
The GAAP bottom line was distorted by the equitization of certain convertible notes. Lumentum reported a GAAP net loss of $7.2 billion, or $84.65 per diluted share, in the fourth quarter, driven by a stated one-time, non-cash loss on debt extinguishment of $7.8 billion. In contrast, fourth-quarter non-GAAP net income was $326.3 million, or $3.23 per diluted share, versus $225.7 million, or $2.37 per diluted share, in the third quarter. The same debt-extinguishment item also drove the fiscal-year GAAP net loss of $6.9 billion.
Cash, cash equivalents, and short-term investments were $2.7 billion at quarter end. This was a decrease of $433.9 million from the end of the third quarter, while the Company also described it as an increase of $1.9 billion from the end of fiscal year 2025. The release did not report operating cash flow, free cash flow, debt balances, share repurchases, or dividends in the provided text.
The outlook calls for first-quarter fiscal 2027 net revenue of $1.225 billion to $1.275 billion, non-GAAP operating margin of 39.5% - 40.5%, and non-GAAP diluted net income per share of $4.05 to $4.35. Management attributed the trajectory to AI-driven optical connectivity demand and highlighted OCS solutions, cloud modules and 1.6T adoption, ultra-high-power CPO lasers, ELS modules, and NPO engagements. The release also identifies product-mix variability, average selling price pressure, costs, capacity, supplier execution, customer demand changes, and debt-related obligations as relevant risks.
Management, verbatim
Lumentum is positioned at the heart of a secular industry shift. As AI compute workloads increase in both speed and bandwidth, data center architects are turning to optical links as a primary means of connectivity.
Michael Hurlston, President and CEO
Looking ahead, our trajectory continues to accelerate as AI demand drives our Q1 revenue guidance midpoint to $1.25 billion, reaching our target model more than a quarter ahead of schedule.
