Lumentum and Coherent emerge as key beneficiaries of the AI-driven photonics upgrade cycle, delivering strong quarterly earnings as hyperscalers replace copper with high-speed optical transceivers.
Lumentum reported a strong earnings beat with EPS of $3.23 versus $2.97 consensus and 109.3% YoY revenue growth, positioning it as a direct beneficiary of the optical transceiver upgrade cycle for AI data centers.
Coherent beat earnings with EPS of $1.74 versus $1.43 consensus and generated $805 million in trailing GAAP net income, giving it profitable, vertically integrated exposure to AI optical infrastructure demand.
Lumentum Holdings and Coherent Corp. are capitalizing on the critical transition from copper cabling to high-speed optical transceivers in AI data centers. Both firms recently posted strong earnings beats, driven by the 800G and 1.6T photonics upgrade cycle that addresses bandwidth bottlenecks and heat management in next-generation server clusters.
Copper cabling struggles to transmit high-speed signals beyond one to two meters without significant signal loss and heat generation, creating latency bottlenecks for AI-focused GPUs.
Investors should monitor high valuation multiples, supply chain disruptions, fabrication yield issues, and market volatility, as indicated by Coherent's high beta of 2.10.
