Lumentum

Lumentum just crossed one billion dollars in quarterly revenue for the first time, landing at 1.01 billion dollars, up 109% from a year ago. Both halves of the business are ripping at once, with components up 103% and systems up 123% year over year. Full year revenue climbed 83% to 3.01 billion dollars.

Making more money is one thing, keeping more of it is another. Gross margin reached 50.4% this quarter, up from 37.8% a year ago, and operating margin more than doubled to 36.6%. Management guided next quarter to 1.225 to 1.275 billion dollars in revenue with operating margins near 40%, hitting their long term target more than a quarter early.

The headline number looks terrifying. Lumentum reported a 7.2 billion dollar loss for the quarter, driven by a one time, non cash 7.8 billion dollar charge from converting debt into stock. No cash left the building, but that conversion creates new shares, and every existing shareholder now owns a smaller slice of the company.

The company is valued around 64 billion dollars, which is more than 20 times its entire annual revenue of 3.01 billion dollars. That leaves almost no room for a stumble. Management also warns that shifting product mix can swing profits quickly, since margins vary widely across their lineup, and tariffs plus rare earth export limits add more uncertainty.
