Topic: Demand breadth, indium phosphide capacity ramp, and supply-demand gap
Key points:
Record bookings in fiscal Q1, with orders extending over a year out; demand broad-based across Datacenter and Communications.
Communications segment saw 5 sequential quarters of growth, with 11% sequential and 55% YoY growth in Q1; expects sequential growth this quarter and through fiscal year.
6-inch indium phosphide production started in September quarter at Sherman, Texas; initial yields higher than mature 3-inch lines; now ramping at second facility in Jarfalla, Sweden, targeting 2x capacity in ~12 months.
Datacenter Q1 grew 4% sequentially, constrained by indium phosphide laser supply; unmet backlog rolled into Q2; internal and external supply growing sequentially from Q1 to Q2 and expected to grow again into Q3.
Mgmt stance: Bullish — record bookings, accelerating 1.6T adoption, and strong customer forecasts through calendar 2028 support continued capacity expansion.
Q2 — Simon Leopold
Topic: Optical circuit switches (OCS) market position and indium phosphide product clarification
Key points:
OCS based on nonmechanical liquid crystal technology; shipped systems to 7 customers; revenue and backlog grew last quarter, expected to grow again this quarter.
Meaningful OCS revenue contribution expected in calendar 2026, weighted toward second half.
Ramping production of 3 indium phosphide products (EML lasers, CW lasers, photodiodes) across 2 sites (Sherman, Texas and Jarfalla, Sweden).
Mgmt stance: Bullish — technology differentiation recognized by customers; TAM larger than originally thought; OCS revenue ramp on track.
Q3 — George Notter
Topic: Manufacturing footprint consolidation and capacity expansion
Key points:
Since beginning of fiscal 2025, sold or exited 23 sites; significant opportunity for further consolidation.
Expanding transceiver module capacity at existing Ipoh, Malaysia facility; new Penang facility already in production; adding module capacity at Vietnam site.
Industrial segment also undergoing consolidation, with some facility investments for expansion.
Mgmt stance: Neutral-to-bullish — active footprint optimization (consolidation and expansion) to support demand and improve return on invested capital.
Q4 — Blayne Curtis
Topic: Datacenter guidance and indium phosphide capacity constraints
Key points:
Primary constraint in prior quarter was indium phosphide capacity, specifically EMLs; significant improvement from Q1 to Q2 in both external and internal supply.
Still somewhat constrained in current quarter; supply expected to improve sequentially through next calendar year.
All EMLs and CW lasers are for internal consumption; qualification for parallel lines is straightforward once a facility is qualified.
Mgmt stance: Neutral — constraints easing but not fully resolved; capacity ramp progressing as planned.
Q5 — Thomas O'Malley
Topic: Segment growth drivers and 6-inch indium phosphide margin impact
Q2 guidance: Datacenter +10% sequential; Communications up single digits sequentially; Industrial stable to slightly up.
6-inch indium phosphide cost less than half of 3-inch; first full quarter of production in Q2; margin impact minimal in Q2, more meaningful through calendar 2026.
Other margin tailwinds: 1.6T products, capacity ramp, and Industrial segment gross margin improvement; company targeting 42% gross margin.
Mgmt stance: Bullish — 6-inch cost advantage and product mix expected to drive gross margin expansion over time.
