Lumentum was upgraded to a Zacks Rank #1 (Strong Buy) following an analyst review that highlighted accelerating demand for optical components and robust margin expansion. The upgrade rationale cites a significant improvement in earnings quality, driven by strategic wins in data‐center networking and emerging AI infrastructure, and reflects consensus estimates that full‐year non‐GAAP EPS could exceed $6.50, a rise of more than 60% over the prior fiscal year.

For the quarter ended December 27, 2025, Lumentum reported net revenue of $665.5 million, up 65.5% year‐over‐year, surpassing consensus forecasts. GAAP gross margin expanded by 1,130 basis points to 36.1%, while non‐GAAP operating margin widened by 1,730 basis points to 25.2%. Non‐GAAP net income reached $143.9 million, or $1.67 per diluted share, compared with $30.0 million, or $0.42 per share, in the prior year period.

Component sales generated $443.7 million of revenue, a 68.3% increase over the prior‐year quarter, driven by high‐speed transceivers and laser modules. Systems revenue climbed 60.1% to $221.8 million, led by optical circuit switches (OCS) and co‐packaged optics (CPO) solutions. Management noted backlog for OCS orders has surpassed $400 million, underscoring strong customer commitments in hyperscale data centers.

Lumentum’s third‐quarter outlook calls for net revenue between $780 million and $830 million, corresponding to year‐over‐year growth above 85%, and non‐GAAP operating margin of 30.0% to 31.0%. The company anticipates non‐GAAP diluted EPS of $2.15 to $2.35. Beyond near‐term targets, Lumentum is advancing two substantial long‐term opportunities: scaling OCS production to meet extraordinary demand and fulfilling a multi‐hundred‐million‐dollar CPO order slated for delivery in the first half of calendar 2027.
