Rosenblatt Upgrades Lumentum Holdings to Buy Amid Data Center and AI Demand Surge

Rosenblatt Securities has upgraded Lumentum Holdings Inc. (LITE) to a Buy rating, reflecting growing confidence in the company’s positioning within the expanding data center and artificial intelligence hardware ecosystem. The firm notes that Lumentum’s advanced photonic integrated circuits and high-bandwidth transceivers are critical enablers for next-generation AI servers and cloud infrastructure, particularly as data traffic scales with generative AI workloads. The analyst firm projects Lumentum’s revenue to grow by 18% year-over-year in fiscal 2026, driven by increased orders from major cloud providers and telecom operators. This growth is underpinned by Lumentum’s market share in 800G and 1.6T optical transceivers, which are now standard in large-scale AI deployments. Rosenblatt also points to a 22% improvement in gross margins expected in the second half of 2026, resulting from supply chain optimization and higher utilization of its manufacturing facilities in Asia. The upgrade follows Lumentum’s recent announcement of a new 1.6T transceiver module for AI clusters, which is set to ship in volume during Q3 2026. The company reported $418 million in revenue for its fiscal Q1 2026, a 14% increase from the prior-year quarter, with adjusted earnings per share of $1.12—above the consensus estimate. These results reinforce the firm’s view that Lumentum is well-positioned to capture outsized growth in the optical connectivity market. Market participants are closely watching LITE’s performance as AI infrastructure investment continues to surge. The stock has seen a 12% rise in the past 30 days, reflecting sentiment around the company’s technical differentiation and contract wins. Analysts suggest the company’s ability to scale production and maintain innovation leadership will be key to sustaining momentum.
