Coherent Corp
Optical transceiver market leader (~22% share) riding the AI datacenter interconnect buildout. FQ3 FY2026 (reported May 2026) revenue $1.81B (+21% YoY); Datacenter & Communications segment hit $1.36-1.4B (+41% YoY), ~75% of total revenue. NVIDIA took a $2B equity stake in Coherent in March 2026 (split from a $4B commitment shared evenly with Lumentum) tied to multi-year 1.6T/co-packaged-optics purchase and capacity agreements; AI optics demand is reportedly booked out through 2028. Coherent is expanding the world's first volume 6-inch indium phosphide fab (Sherman, TX + Järfälla, Sweden) with fully automated wafer processing, backed by a $50M CHIPS Act grant, targeting 4x InP capacity by end-2027. Stock up ~80%+ YTD in 2026 alongside peers Lumentum (+98%) and Applied Optoelectronics (+233%) before a early-July pullback on CPO-timing jitters.
Scenarios
#1 market share in the fastest-growing datacenter interconnect category; NVIDIA's equity stake plus multi-year purchase commitments de-risk demand visibility through 2028; the automated 6-inch InP fab gives a manufacturing cost and capacity edge that rivals can't quickly replicate, and Coherent is investing in co-packaged optics itself rather than only defending pluggables.
~75% revenue concentration in a single demand cycle (hyperscaler AI capex) leaves little diversification cushion; co-packaged optics — Broadcom and NVIDIA embedding photonics directly onto switch/GPU substrates — threatens to bypass pluggable transceiver vendors inside the rack over the next few years; and a rich valuation (mid-100s P/E) after an 80%+ YTD run leaves little room for any hyperscaler capex slowdown or 800G/1.6T execution miss.
Key Factors to Watch
- ●FQ3 FY2026 revenue $1.81B (+21% YoY); Datacenter & Communications segment $1.36-1.4B (+41% YoY), ~75% of total revenue
- ●NVIDIA $2B equity investment (March 2026) plus multi-year 1.6T/CPO purchase and capacity agreement (split from a $4B commitment shared with Lumentum)
- ●1.6T transceivers ramping fast; first co-packaged-optics platform revenue booked; AI optics demand reportedly booked out through 2028
- ●World's first volume 6-inch InP fab (Sherman, TX + Järfälla, Sweden), fully automated wafer processing; capacity to quadruple by end-2027, backed by $50M CHIPS Act grant
- ●Competes directly with Lumentum (also NVIDIA-backed, $2B) and Applied Optoelectronics; co-packaged optics is the key long-term disruption risk to the pluggable-transceiver business model
