Reviewed listing: NASDAQ:LITE · Analysis dated Oct 22, 2026
It has not been confirmed whether the basis of this analysis still holds today. Read it as a dated earlier assessment; it does not establish a current buying opportunity.
How does the company make money?
Lumentum makes optical components and lasers. Among other things, they help transmit data quickly in data centers and communications networks.
What supports the business?
Quarterly revenue rose to 1,006.3 million USD, more than doubling from the prior year. The operating margin also improved significantly.
What could improve?
The expansion of AI data centers could require more optical connections over the longer term. Higher unit volumes and better utilization could increase earnings power.
How is the stock price assessed?
This assessment refers to the analysis and its quoted price shown here. It is not a live quote or a personal recommendation to buy.
850.70 USD are expensive. Even compared with four times the next adjusted quarterly earnings forecast, the ratio is around 51. My cautious ceiling is 504 USD.
What is the main risk?
A decline in demand, customer concentration, or new competitors could quickly compress high margins. Convertible bonds and stock-based compensation make dilution especially important.
What is the overall assessment?
Lumentum's optical technology is benefiting substantially from data center construction. At the high share price, however, the risk of extrapolating exceptional growth and margin levels for too long outweighs the positives.
