Can Indium Phosphide Capacity Expansion Drive Growth for LITE's Stock?
Read MoreHide Full Article
Key Takeaways
Lumentum is boosting indium phosphide wafer output 40% as AI data-center demand exceeds supply by 25-30%.
Lumentum benefits from owned indium phosphide fabs and long-term hyperscaler supply deals through 2027.
The Zacks Consensus Estimate pegs LITE's fiscal 2026 revenues at $2.91B, up 76.89% year-over-year growth.
Lumentum Holdings (LITE - Free Report) is expanding its indium phosphide wafer fabrication capacity at an accelerated pace. The company is positioning itself to capture growing demand from hyperscalers investing in AI infrastructure. Indium phosphide is the foundational substrate for high-speed laser chips used in optical transceivers, optical circuit switches and co-packaged optics. These components are non-negotiable in modern AI data centres. Global manufacturing capacity for this material is structurally limited, and Lumentum is one of the few players capable of producing at the precision and volume that hyperscalers require.
Demand is outpacing supply. Lumentum is currently under-shipping customer demand by roughly 25% to 30%. LITE is targeting a 40% increase in wafer output across its Sagamihara, Caswell and Takao fabrication facilities. More than half of that was delivered within the fiscal second quarter alone, ahead of schedule. All existing capacity is committed under long-term agreements through calendar 2027, stabilizing pricing and locking in allocation for its most strategic customers. Volumes above contracted levels are being negotiated at a premium, giving the company a pricing lever that operates independently of volume growth.
This expansion is gaining traction as customer demand continues to intensify. LITE reported revenues of $665.5 million in the fiscal second quarter, representing 65.5% year over year growth. The Zacks Consensus Estimate for LITE's fiscal 2026 revenues is pegged at $2.91 billion, up 76.89% year over year. With demand continuing to outpace supply, Lumentum's indium phosphide capacity expansion could prove central to its next phase of growth.
LITE Enjoys a Competitive Edge
Lumentum stands out among peers Coherent Corp (COHR - Free Report) and Fabrinet (FN - Free Report) in the AI-driven optical components space. While Coherent competes in indium phosphide laser markets, its broader telecom and industrial exposure limits the focused operating leverage Lumentum is generating from its concentrated AI infrastructure positioning. Fabrinet's contract manufacturing model leaves it exposed to indium phosphide supply constraints that Lumentum's owned fabrication network avoids entirely. Neither Coherent nor Fabrinet has demonstrated comparable depth in long-term hyperscaler supply commitments for indium phosphide-based components. This positions Lumentum as the higher-conviction AI photonics play among the three.
Lumentum shares have surged 312.2% in the past six months compared with the Zacks Communication - Components industry’s appreciation of 97.6% and the Zacks Computer and Technology sector’s return of 3.3%.
