Lumentum stock faces a stronger growth outlook after a sharp fiscal first-quarter revenue increase. Management expects another major step in Q2.

Growth broadens across Lumentum's portfolio

Fiscal first-quarter revenue rose sharply year over year, led by pump lasers and optical circuit switches.
Management expects another strong revenue step in fiscal second quarter and forecasts non-GAAP operating margins above 45 percent.
A second major NPO/CPO win and purchase commitments exceeding $5 billion strengthen visibility, although execution remains central.

Lumentum reported a sharp expansion in its fiscal first quarter on November 2, with growth across its businesses and a further increase expected in the following quarter. In its investor release, the company said pump lasers and optical circuit switches were the leading contributors.

Lumentum stock traded at 559.75 euros on Lang & Schwarz at 14:04 CET on Thursday, November 12, 2026, 7.69 percent below the Xetra close of Wednesday, November 11. The comparison uses the previous Xetra session because the German market was still open during the quote.

Revenue growth accelerates

Net revenue reached $1.2626 billion in the three months ended September 26, 2026. That was 25.5 percent above the fourth fiscal quarter and 136.5 percent above the year-earlier quarter. Components generated $754.2 million, while Systems contributed $508.4 million; both businesses grew from the prior-year period.

GAAP gross margin increased to 51.0 percent from 34.0 percent a year earlier, and GAAP operating margin rose to 28.5 percent from 1.3 percent. GAAP net income was $360.3 million, or $3.54 per diluted share, compared with $4.2 million, or $0.05 per diluted share, in the year-earlier quarter.

The sequential GAAP comparison requires context. The fourth quarter included a $7.7566 billion loss on debt extinguishment, which contributed to a reported net loss of $7.1617 billion. On a non-GAAP basis, net income increased to $461.1 million from $86.4 million a year earlier and from $326.3 million in the prior quarter.

Management raises the growth bar

Chief Executive Michael Hurlston said Lumentum secured its second major NPO/CPO win during the quarter, backed by purchase commitments exceeding $5 billion. He also said demand visibility for optical circuit switches had expanded significantly and could position optical switching as a multi-billion-dollar annual revenue stream.

For fiscal Q2 2027, management forecasts revenue of $1.575 billion to $1.625 billion. The guidance implies a further sequential increase and includes a non-GAAP operating margin of 45.0 percent to 46.0 percent and non-GAAP diluted earnings per share of $5.90 to $6.20. Hurlston said the company expects roughly $350 million of sequential revenue growth and an operating margin above 45 percent.

The outlook puts execution and capacity expansion at the center of the investment case. Lumentum's release also cited stronger cloud modules performance and improving gross margins in that business. At the same time, the company's own risk factors include customer demand changes, order delays or cancellations, manufacturing capacity and product-mix effects on profitability.
