Lumentum stock: Q2 outlook points to another sharp growth step

Lumentum reported a sharp acceleration in its fiscal first quarter on November 2, as demand for optical infrastructure lifted revenue and management raised expectations for the following quarter. The company announcement carried by FT.com said the results covered the three months ended September 26, 2026.

Lumentum stock traded at 516.70 euros on Lang & Schwarz at 1:37 p.m. CET on Tuesday, November 10. The quote provides the current market context, while the company's earnings outlook remains the central driver for investors assessing the shares.

Revenue growth broadens

Fiscal first-quarter revenue reached USD 1.2626 billion, up 25.5 percent from the previous quarter and 136.5 percent from the year-earlier period. Components revenue rose 98.9 percent year over year to USD 754.2 million, while systems revenue increased 228.8 percent to USD 508.4 million.

Management identified pump lasers and optical circuit switches as the leading contributors. It also pointed to continued strength in cloud modules, where gross margin improved. GAAP gross margin was 51.0 percent, compared with 34.0 percent a year earlier, and GAAP operating margin reached 28.5 percent versus 1.3 percent.

GAAP net income was USD 360.3 million, or USD 3.54 per diluted share, compared with USD 4.2 million, or USD 0.05 per diluted share, in the year-earlier quarter. The company also reported non-GAAP net income of USD 461.1 million, or USD 4.57 per diluted share. The adjusted figures exclude items including stock-based compensation, amortization of acquired intangibles and other specified charges, so investors should distinguish them from the GAAP result.

Second-quarter expectations rise

Lumentum expects fiscal second-quarter revenue between USD 1.575 billion and USD 1.625 billion. The outlook calls for a non-GAAP operating margin of 45.0 percent to 46.0 percent and non-GAAP diluted earnings per share of USD 5.90 to USD 6.20.

Chief Executive Michael Hurlston said the company anticipates sequential revenue growth of approximately USD 350 million and expects operating margin to exceed 45 percent. Lumentum said optical switching could become a multibillion-dollar annual revenue stream as demand visibility expands.

The company also reported a second major NPO/CPO win backed by purchase commitments exceeding USD 5 billion. That commitment supports the longer-term investment case for optical connectivity, although delivery timing, customer spending and manufacturing capacity remain important execution factors.

What investors should watch

The quarter shows that growth is no longer concentrated in a single product category: components and systems both expanded, with optical switching supplying particularly strong momentum. The outlook nevertheless depends on Lumentum increasing production and meeting customer requirements as AI and cloud infrastructure demand accelerates.
