Oct 5

3 min read

Summary | Lumentum becomes a core engine of AI infrastructure, with revenue at a record high for the second straight quarter

Lumentum delivered a strong FY26 Q2, with revenue reaching $665.5M, a record for the second consecutive quarter. Management is extremely bullish: the $750M quarterly revenue target originally set for mid-FY26 is now expected to be comfortably exceeded as soon as next quarter (Q3). The company's three growth engines — Cloud Transceivers, OCS (optical circuit switches) and CPO (co-packaged optics) — all show strong momentum. OCS demand in particular has surged, with backlog now above $400M. Meanwhile, 200G/lane EML chip capacity is sold out, with unfilled demand as high as 30%, showing that Lumentum has transformed from a traditional telecom vendor into a core supplier for AI data centers.

2. Financials (Non-GAAP)

Revenue: $665.5M (YoY +65%).
Gross margin: 42.5% (QoQ +310 bps, YoY +1,020 bps). Driven by higher capacity utilization and a better 200G product mix.
Operating margin: 25.2% (QoQ +650 bps, YoY +1,730 bps).
EPS: $1.67 (beat expectations).
Opex: $114.9M (higher R&D and G&A spending to support the AI opportunity).
Cash: $1.16B (up $33M QoQ).
CapEx: $84M (focused on cloud and AI capacity expansion).
Segment performance:
- Components: $443.7M (YoY +68%).
- Systems (systems/modules): $221.8M (YoY +60%).

3. Outlook (FY26 Q3)

Revenue guidance: $780M - $830M (midpoint $805M, YoY +85%).
Operating margin: 30% - 31%.
EPS guidance: $2.15 - $2.35.
Growth mix: About 2/3 of the revenue increase is expected from Components (cloud applications) and 1/3 from Systems (1.6T transceivers and OCS ramp).

4. Product Updates

Components (Laser Chips):
- EML capacity: Running fully loaded. The 40% capacity expansion at the Sagamihara fab is more than halfway complete.
- Technology progress: 200G chips account for only 5% of unit shipments but already contribute 10% of data center chip revenue, a significant ASP advantage.
- Supply chain: Capacity at the Caswell (UK) and Takao (Japan) fabs is expected to come online in 2H 2026.
Systems (Transceivers & OCS):
- 1.6T progress: Demand for 1.6T transceivers is ahead of expectations, and Lumentum is among the market leaders on ramp timing.
- OCS: Backlog has reached $400M+, most of it shipping in the first half of FY2027 (2H calendar 2026).
CPO / AI-related:
- New orders: Won several hundred million dollars of ultra-high-power (UHP) laser orders, expected to ship in 1H 2027.
- ELS (external light source): Shifting from supplying bare chips to ELS modules, lifting ASP by 2-2.5x.

5. Looking Ahead

Optical scale-up trend: As copper hits its physical limits, CPO is expected to enter the scale-up (in-rack interconnect) market by late 2027 — an entirely new expansion opportunity.
Capacity footprint: The Nava plant in Thailand is running at full speed, and the company has brought in senior executives from Jabil to strengthen Contract Manufacturing (CM) partnerships and relieve back-end assembly and test pressure.
Commercial strategy: All EML capacity is covered by customer LTAs (long-term agreements) through the end of 2027. The LTAs lock in volume and also serve as the baseline for price negotiations.

6. Q&A Highlights

Key question: How big is the capacity gap?
- Management: Despite a 20% capacity increase, supply still falls about 30% short of customer demand. It is a "good problem to have"; the company is squeezing out more output through line optimization and yield improvement.
Key question: Which technology path for 1.6T (EML vs SiPh)?
- Management: Early 1.6T will be mostly EML (especially WDM architectures), but over the long term Silicon Photonics should gain share in parallel-fiber applications. Lumentum plays in both, and even as SiPh grows, absolute EML demand will keep rising.
Key question: Pricing negotiations and margin outlook?
- Management: Price increases have already gone through on some products. As the 200G mix rises from 5% to 25% by year-end, ASP and gross margin will continue to benefit.

7. Risks and Watch Items

Capacity bottleneck: Fab capacity is fully pre-allocated; any delay in expansion would cap the revenue ceiling.
Customer concentration: Although OCS has expanded to 3 customers, cloud transceiver revenue still depends heavily on a few hyperscalers.
Weak industrial market: The industrial laser segment remains in a cyclical downturn and will not contribute growth in the near term.

8. Bottom Line

One-line positioning: The company is in an explosive growth phase as it transforms from a traditional telecom supplier into a core component vendor for AI infrastructure.
Core moat: Industry-leading high-power laser (InP platform) technology and subsea-grade reliability leave it with almost no competitors of comparable scale in CPO external light sources and OCS.
Investment takeaway: With dual "systems + components" engines, and as the 1.6T transition and OCS orders convert, revenue and margins should step up together over the next 6-8 quarters.
