Lumentum manufactures optical and photonic products through two principal business segments: Optical Communications (OpComms), which supplies components, modules, and subsystems for transmitting video, audio, and data across networks, and Commercial Lasers, which serves industrial and commercial applications.

The company generates revenue through the design, development, and sale of specialized optical and photonic components and systems to telecommunications infrastructure providers, data center operators, and industrial customers globally.

Lumentum's primary customers include major telecommunications equipment manufacturers, cloud service providers, and data center operators across the Americas, Asia-Pacific, Europe, the Middle East, and Africa.

Lumentum Holdings Inc. is a global leader in optical and photonic product manufacturing with a market capitalization of $68.4 billion and approximately 10,562 employees. The company leverages advanced photonic technology to address critical infrastructure demands in telecommunications and industrial markets, positioning itself at the intersection of 5G deployment, data center expansion, and industrial automation. Lumentum's competitive advantage derives from its specialized expertise in optical component design and manufacturing, enabling it to serve as a critical supplier to the world's largest telecommunications and technology infrastructure providers.

Hurlston handed back 6,185 shares to cover taxes when restricted stock vested on August 19, and he still holds 112,794 directly. Notably, the stock's run is so staggering it's showing up in the financials, including Lumentum's convertible notes, which went in the money and prompted management to equitize a chunk of them in the June quarter. That cut debt by $1.1 billion and booked a $7.8 billion non-cash charge, turning a strong quarter into a $7.2 billion GAAP net loss.

Underneath it, revenue reached $1.01 billion, up 109% year over year, with non-GAAP operating margin at 36.6% against 15% a year earlier. Guidance for the September quarter calls for about $1.25 billion and margins of 39.5% to 40.5%, hitting the target model a quarter early, with much more booming demand to go. Hurlston told analysts on the August 11 call that Lumentum is "way behind" on high-powered laser shipments. To help bridge that gap, the company went out for more indium phosphide substrate from AXT
