New York, Jan 20, 2026, 18:56 EST — After-hours
- Lumentum shares climbed roughly 10% during Tuesday’s regular session and stayed close to $356.83 in after-hours trading.
- Skye Chen of Aletheia Capital raised the price target to $500 from $330, citing stronger demand for high-speed data-center lasers.
- Lumentum will report its fiscal Q2 results on Feb. 3, after the market closes.
Lumentum Holdings Inc (LITE) shares jumped roughly 10% on Tuesday, closing at $356.83 and holding steady around that price in after-hours trading.
The shift follows growing interest in firms linked to faster networking within AI data centers, right before Lumentum’s upcoming earnings report. Aletheia Capital’s Skye Chen bumped his price target to $500 from $330, maintaining a buy rating. He highlighted “significantly stronger EML demand” driving the next surge in high-speed links. 1
Lumentum edged higher despite a tough day for stocks overall: the Nasdaq Composite dropped 2.39%, and optical networking rival Ciena declined 0.91%, per a Nasdaq.com market summary.
EML, or electro-absorption modulated laser, is a type of laser used in optical transceivers to transmit data over fiber at extremely high speeds. The term “800G” denotes 800 gigabits per second, marking a new milestone as data centers upgrade to handle increased traffic driven by AI workloads.
Aletheia highlighted a quicker shift to 200-gigabit SerDes (serializer-deserializer data interfaces that transfer bits on and off chips) along with stronger pricing. The firm expects EML prices to climb 15%-20% in the December 2025 quarter and 5%-7% in March 2026. It also noted supply risks related to indium phosphide substrates for laser chips appear manageable. 2
Lumentum plans to report its fiscal second-quarter results on Tuesday, Feb. 3, after the U.S. market closes. The company will hold an earnings call at 5 p.m. ET. 3
That report will also test the company’s guidance. In November, Lumentum projected fiscal second-quarter revenue between $630 million and $670 million, with non-GAAP earnings per share ranging from $1.30 to $1.50. 4
The bar is climbing. With the stock surging and “800G” demand already factored into many models, even a hint that prices are plateauing or supply is tightening could knock the shares hard. A wider slowdown in data-center spending would have a similar impact.
Attention is also on SPIE Photonics West in San Francisco this week. Lumentum revealed it will present laser platforms designed for precision manufacturing and sensing applications at the conference. 5
Lumentum stock faces a key test on Feb. 3, when investors will zero in on its numbers and clear guidance on 800G demand, pricing, and the pace of production ramp-up for the March quarter.
