Quarterly Performance Breakdown

Lumentum posted non-GAAP earnings of $1.67 per share for the second quarter of fiscal 2026, surpassing the Zacks Consensus Estimate by nearly 19%. Revenue also exceeded expectations, growing 24.7% sequentially and 65.5% year-over-year to $665.5 million. The Components segment was the primary growth driver, contributing 66.7% of total revenue and climbing 68.3% to $443.7 million. The Systems segment accounted for 33.3% of revenue, rising 60.1% to $221.8 million.

The company benefited from robust demand in the cloud sector, with record shipments of electro-absorption modulated laser (EML) chips and a favorable shift toward higher-priced 200G-lane products. Systems revenue also saw a boost, supported by strong transceiver shipments and an earlier-than-expected contribution from optical circuit switches (OCS).

Segment Insights and Product Trends

Components: Lumentum set a new record for EML chip shipments, particularly in 100G lanes, while 200G devices, though only 5% of volume, made up 10% of data center laser chip revenue. Narrow linewidth laser assemblies achieved their eighth consecutive quarter of growth, pump lasers saw revenue more than double, and coherent/line subsystems also expanded.

Systems: Growth was fueled by cloud transceivers as production ramped up in Thailand. Management anticipates further revenue layering from larger transceiver suppliers in the next quarter. OCS exceeded $10 million in quarterly revenue for the first time, ahead of schedule, indicating strong execution and early customer adoption. Industrial laser shipments remained steady but soft due to cyclical factors.

Operating Metrics for Q2

Non-GAAP gross margin improved to 42.5%, up from 32.3% a year earlier, driven by better manufacturing efficiency, higher yields, and strategic pricing. Selling, general, and administrative expenses dropped to 6.8% of revenue (down 220 basis points), while R&D expenses fell to 10.5% of revenue (down 500 basis points). Total non-GAAP operating expenses were $114.9 million, reflecting ongoing investment in cloud and AI R&D alongside disciplined cost management. The non-GAAP operating margin jumped to 25.2% from 7.9% last year.

Balance Sheet and Capital Allocation

As of December 27, 2025, Lumentum held $1.16 billion in cash and equivalents, a $33 million increase from the prior quarter. The company refinanced part of its debt, issuing new 2032 convertible notes and partially buying back 2026 notes, while also executing a capped call purchase. Management is working with customers to support capacity investments and is accelerating contract manufacturing to relieve supply constraints and optimize production for higher-value products. Capital expenditures reached $84 million, primarily aimed at expanding manufacturing for cloud and AI clients.

Management's Near-Term Outlook

For the third quarter of fiscal 2026 (ending March 2026), Lumentum expects revenue between $780 million and $830 million (midpoint: $805 million), representing over 85% growth year-over-year. About two-thirds of the sequential revenue increase is projected to come from Components, with the remainder from Systems. The company anticipates an operating margin of 30%-31% and EPS in the range of $2.15 to $2.35.
