Shares of Lumentum Holdings (NASDAQ:LITE | LITE Price Prediction) surged 14% to $932 on Wednesday afternoon after a blowout fiscal Q4 report the prior evening. The move dragged the entire optical networking complex higher, with Nokia (NYSE:NOK), Celestica (NYSE:CLS), Applied Optoelectronics (NASDAQ:AAOI), and Ciena (NYSE:CIEN) all rallying in sympathy.
Lumentum’s Blowout Earnings Report Resets Expectations
Lumentum reported adjusted EPS of $3.23 versus a $2.99 estimate on revenue of $1.01 billion, up 109.3% year over year from $480.7 million. Non-GAAP gross margin expanded 1,260 basis points to 50.4%, and management guided Q1 FY27 revenue to $1.225 billion to $1.275 billion with EPS of $4.05 to $4.35, hitting its target operating model more than a quarter ahead of schedule. Details are in the company’s 8-K filing.
CEO Michael Hurlston framed the quarter as a structural inflection, saying “Lumentum is positioned at the heart of a secular industry shift. As AI compute workloads increase in both speed and bandwidth, data center architects are turning to optical links as a primary means of connectivity.” Components revenue jumped 102.7% and Systems climbed 122.6%, both fueled by hyperscaler transceiver and 1.6T module demand. Reports of an FCC plan to restrict new Chinese optical transceivers added a tailwind for Western suppliers.
The Halo Effect Sweeps Peers Higher
Nokia climbed 9% to $10, extending momentum from its July 23 earnings beat where AI and cloud orders reached about 2.8 billion euros. Analyst target hikes from BofA and SEB in the prior session added fuel, and its NVIDIA-partnered AI-RAN platform ties it directly to the day’s optics narrative. The Infinera acquisition has already deepened Nokia’s optical networking exposure.
Celestica advanced 9% to $339 with no company-specific catalyst, a pure read-through on AI hardware demand. Its Connectivity & Cloud Solutions segment already grew 84% year over year to $3.81 billion last quarter, and management raised FY26 revenue guidance to $20.5 billion.
Applied Optoelectronics added 3% to $138, a more muted move after a monster run. AAOI is up 296.1% year to date, with its datacenter segment more than doubling last quarter and 800G volumes ramping fast.
The Whole Optical Group Re-Rates
Ciena was the biggest halo mover, jumping 11% to $432. The day reflects the market re-underwriting AI-driven optical demand across the group, not just one company’s beat. Ciena’s cloud provider revenue reached 46% of total last quarter, up 70% year over year, and CEO Gary Smith has said his strategy is “tightly aligned to the structural, multi-year opportunities created by AI-driven demand.”
The Big Picture
The rally amplifies stretched valuations. Lumentum trades at a forward P/E near 47 after climbing 153% year to date and 679% over the past year. Each name in this cohort is now leveraged to hyperscaler AI capex plans, transceiver supply capacity, and geopolitical trade policy. Nokia specifically faces order-to-revenue conversion questions and cash-flow scrutiny that a strong stock move masks.
Still, optics continues to have significant tailwinds as copper hits its physical limits and more optics is required to continue networking large clusters of AI accelerators. Investors are paying up significantly for optics stocks, but they’ll likely see revenue growth that outpaces the broader AI infrastructure space for years to come.
