New York, February 10, 2026, 17:43 EST — After-hours
Lumentum Holdings Inc shares fell 2.8% to $561.13 in after-hours trading on Tuesday after swinging sharply in the regular session. The stock traded as high as $579 and as low as $531, with about 4.8 million shares changing hands.
The move matters because Lumentum has become a high-beta proxy for AI-linked data-center buildouts, where small shifts in order timing can hit expectations fast. With the stock still digesting a big run, investors are looking for fresh color on demand, supply and pricing.
It also lands ahead of a stretch of conference appearances where management Q&A can do more work than a press release. Traders tend to treat those events as real-time checkups on whether the growth story is intact — or getting ahead of itself.
Lumentum on Tuesday announced management is scheduled to take meetings at Susquehanna’s 15th Annual Technology Conference on Feb. 26 and to present at Morgan Stanley’s Technology, Media & Telecom Conference on March 2, including a webcast and an 11:30 a.m. Pacific presentation slot. 1
The company last week reported fiscal second-quarter revenue of $665.5 million and adjusted earnings of $1.67 per share, and forecast fiscal third-quarter revenue of $780 million to $830 million with adjusted EPS of $2.15 to $2.35. Chief Executive Michael Hurlston said revenue hit the high end of guidance, while pointing to optical circuit switches (equipment that routes data with light inside networks) and co-packaged optics (moving optics closer to chips to cut power) as key drivers. 2
On the earnings call, Hurlston told analysts the company was “recognized as a foundational engine of the AI revolution,” language that has helped frame the stock’s steep re-rating in recent sessions. 3
Elsewhere in the optical and AI plumbing trade on Tuesday, Coherent fell 5.9%, while Broadcom slipped 1.0% and Marvell Technology edged down 0.4%.
But the setup cuts both ways. When expectations lean heavily on rapid ramps, any hint of slower customer spending, tighter supply, or a margin giveback can drag the shares hard, even if the longer story stays in place.
For the next session, investors will watch whether the stock can stabilize after the pullback, and whether trading stays tied to the broader AI-infrastructure tape rather than company-specific headlines.
The next clear catalyst is management’s conference circuit, starting with the Susquehanna meetings on Feb. 26 and the Morgan Stanley webcast on March 2 at 11:30 a.m. Pacific time. 4
