Lumentum Stock Surges 570% in 12 Months, Outpacing Nvidia and Micron

Lumentum has quietly become a major winner of the AI infrastructure boom. Its shares climbed roughly 570% over the past year, leaving Nvidia, Dell, and even Micron behind.

On October 6, the stock added 3.82%, closing at $1,133.40, just under its 52-week high of $1,137.20.

Even for a market fixated on AI, the rally stands out. Over the same 12 months, Micron gained about 457% and Dell rose roughly 308%. Nvidia gained around 28%.

That means Lumentum delivered more than 21 times Nvidia’s return. Its market capitalisation now stands at roughly $101.7 billion.

Causes Behind Lumentum’s Stock Surge

Lumentum manufactures lasers and optical components used in data centers, telecom networks, and AI infrastructure.

As companies build larger AI systems, they need faster connections between servers and data centers, which has driven more investment into optical networking suppliers.

The financial results reflect this. Fiscal fourth-quarter revenue reached $1.01 billion, up 109.3% year over year. Earnings of $3.23 per share also beat expectations.

Citigroup has pointed to demand for optical circuit switches as another major growth driver.

$COHR and $LITE are both up over 10% after a report said U.S. could restrict Chinese optical transceivers starting at 3.2T without touching today’s 800G and 1.6T buildout.
