Lumentum reported a blowout quarter with revenue and margins well above expectations, driven by explosive AI-related demand for its lasers and transceivers. The company significantly raised its outlook, hitting its $1.25B revenue target a quarter early and guiding to operating margins above its target model. Management provided encouraging updates on the CPO/NPO transition, noting accelerating demand and new product wins like ELS modules, while highlighting supply chain tightness and strategic moves to secure more substrate. Q4 FY26 revenue was $1.01B (+109% YoY), with non-GAAP EPS of $3.23, both well above guidance.

Management provided encouraging updates on the CPO/NPO transition, noting accelerating demand and new product wins like ELS modules, while highlighting supply chain tightness and strategic moves to secure more substrate. Q4 FY26 revenue was $1.01B (+109% YoY), with non-GAAP EPS of $3.23, both well above guidance.
Q1 FY27 revenue guidance of $1.225-1.275B and operating margin of 39.5-40.5% far exceeded expectations and targets.
Demand for high-power lasers for CPO/NPO and EML lasers is significantly ahead of supply, driving Lumentum to secure additional substrate supply from AXTI.
The transition to 1.6T transceivers is accelerating, with 200G per lane EMLs now 25% of EML revenue, and the first ELS module order for CPO was received.

Demand
High-power laser demand increased significantly
Demand signals are strong across EMLs, high-power lasers, and pump lasers, with high-power lasers particularly oversold due to accelerating demand. OCS and 1.6T transceivers are seeing robust growth, with bookings visibility extending into 2027.

Capex
Investment and capacity
Quarterly CapEx was $167 million for capacity expansion. Management is ramping internal fabs in Japan and expanding Greensboro for indium phosphide, with long-term supply agreements offsetting planned capex. Capacity expansion is on track for early 2028 revenue.
Tone · Confident
Management conveyed strong execution, raised guidance ahead of schedule, and expressed confidence in future growth opportunities including NPO and CPO, despite some supply constraints.

“We have a distinctive ability to deliver at scale to a very tight set of specifications, which enables superior yields in transceiver manufacturing.”
Demand for high-power lasers for CPO/NPO has accelerated significantly, leaving Lumentum 'further behind' supply despite execution being on plan, and has driven them to secure additional substrate supply from AXTI.
“If one vector has really changed since the last time you and I talked, I'd say it's your high-powered lasers. are very much further behind. The demand signal has increased, and we are very much further behind relative to our ability to sup…”
Lumentum's 200 gig per lane CW lasers are now commanding a significant price premium due to their ability to provide superior transceiver yields for customers, closing the margin gap with EMLs.
“we are commanding a significant price premium, as I said in a previous question, against what we view as the market price because of the performance of these lasers.”
Lumentum is shipping its first ELS module orders for CPO, a higher-ASP product but with slightly lower margins than selling individual lasers, indicating a strategy to grow revenue while enabling customers who cannot handle bare laser chips.
“We got our first ELS module order, right? Which from an ASP standpoint is meaningfully higher than the set of lasers that we ship in.”
Demand for high-power lasers for CPO/NPO has accelerated significantly, leaving Lumentum 'further behind' supply despite execution being on plan, and has driven them to secure additional substrate supply from AXTI. — This indicates that the industry's shift to CPO/NPO architectures is happening faster than expected, creating a supply bottleneck on critical laser chips and benefiting the upstream substrate suppliers like AXTI.
“we went out and we found additional substrate help from AXTI. They've been a great partner. Wupen's worked with them for a good number of years.”
Hi, guys. Thanks very much. Congrats on all the success here. I guess I wanted to ask about, you know, indium phosphide substrate supply. I was really intrigued by the deal you guys signed in the quarter with AXT because I think a quarter ago you actually said that you were doing pretty well on indium phosphide substrate. feels like there's a bit of a change here. I guess I'm wondering like what you guys are seeing longer term here in terms of your need for more indium phosphide substrate. And as I extrapolate that, can I look at Greensboro and are you making more progress towards filling the rest of that facility? I'm looking forward. Thanks a lot.
Hey, George. Yeah, look, I would agree. I mean, I think what we tried to hint to in a previous question is The ultra-high powered laser demand has surprised us, and that cuts across a couple of customers. So what we're trying to do, I think really in the last three months, is secure even more substrate supply. We were doing well. We felt like we had given the baseline of demand that we were seeing from ultra-high powered, and then of course the EMLs and CW lasers that go into our scale-out products, we felt Pretty good, right, as you said. But I think we've seen a pretty big surge in demand, as we said. And in order to respond to that, we went out and we found additional substrate help from AXTI. They've been a great partner. Wupen's worked with them for a good number of years. And we think we're going to need their help, just given the surge in demand. So that's what drove that deal. You know, if this vector continues, we're probably going to need to look for more help on substrate. We feel we're good at this moment. We're probably pretty comfortable just given our lead arrangement with a Japanese supplier and now the announced deal with AXTI. But, you know, given the rate of change in the demand vector that we're seeing, that may not be true a quarter or two from now either.
