Coherent, Inc.
Analysis
Across four calls one change stands out: Coherent is no longer a collection of photonics businesses but a capacity-limited supplier to AI data centres. Demand is booked into 2028; what decides revenue now is how fast its own factories turn out lasers. How much of the 2028 order book is firm purchase orders?
- Demand is no longer the constraint; production is.
Management reported record bookings in three straight quarters and orders reaching into calendar 2028; the limit, it said, is laser output rather than customer appetite. Growth is now an execution number. Is indium phosphide still the binding constraint this quarter?
- The 6-inch indium phosphide ramp does two jobs at once.
Output doubling landed early and yields beat the mature older lines. A 6-inch wafer yields four times the chips at half the cost, so the same ramp lifts how much it ships and what each shipment earns.
- Capacity spending has outrun the cash the business makes.
Capital spending hit $563 million in one quarter against $69 million of cash from operations, and free cash flow was negative by over $1 billion in FY2026. If orders land slower, it is left holding stock and plants built for demand. How much of the FY2026 capital spending went into indium phosphide?
- Capacity ramp sets growthThe bull case is that demand exceeds what Coherent can build, so revenue growth depends mainly on how fast indium phosphide capacity comes online.
- New optical platformsOptical circuit switching and co-packaged optics add new sales layers on top of transceivers, widening the company's share of optical content in AI networks.
- Margins and balance sheetCheaper six-inch wafer production plus a much smaller debt load should let earnings grow faster than sales, which is the core of the profitability case.
- AI customer concentrationThe bear case is that a handful of AI data center buyers drive most of the growth, so any pause in their network spending would hit revenue quickly.
- Cash tied up in capacityCapital spending has outrun cash generation, so the payback on new factories depends on demand holding up long enough to fill the added capacity.
- Pricing fixed in contractsLong-term supply agreements fix prices for years, which limits how much Coherent can earn if shortages persist or if its own costs move against it.
