Understand How Coherent and Lumentum Bypass an AI Bottleneck With Optics
AI-summarised brief · reviewed before publication
Optical suppliers Coherent and Lumentum reported strong fourth-quarter earnings, driven by the AI industry’s shift from copper to optical connectivity. Coherent posted $2.045 billion in revenue, a 33.7% year-over-year increase, with its Datacenter & Communications segment growing 59%. The company beat non-GAAP EPS estimates by 7.60%. Lumentum reported $1.006 billion in revenue, surging 109.3% annually, while achieving a 50.4% non-GAAP gross margin. Both companies exceeded expectations as AI clusters require higher data transfer speeds. Coherent leverages vertical integration, owning the full module stack, while Lumentum focuses on high-margin laser components. Coherent guided Q1 FY27 revenue to $2.20 billion–$2.40 billion. Lumentum projected $1.225 billion–$1.275 billion with operating margins of 39.5%–40.5%. Investors are monitoring whether Coherent’s scale and Lumentum’s margin expansion will sustain as optical interconnects become critical infrastructure for next-generation AI datacenters.
💡 Why It Matters
- · The divergence in business models reveals two distinct paths to capturing value in the optical interconnect market.
- · Coherent bets on volume through vertical integration, while Lumentum prioritizes high-margin component specialization.
- · This split determines which strategy yields superior returns as AI infrastructure scales.
