Notes
Coherent (formed via II-VI's 2022 acquisition of legacy Coherent Inc.) is a leading supplier of 800G/1.6T optical transceivers for AI datacenter networking, a key growth driver alongside NVIDIA's GPU buildout. Also supplies EUV pellicles and laser components into semi capex. Faces intense competition in transceivers from Lumentum and Chinese rivals like InnoLight, with margin pressure from vertical integration by hyperscalers.
Coherent (COHR) filed an 8-K covering Q4 FY2026 results (fiscal year ends June 30) alongside a Regulation FD disclosure that likely includes management commentary and updated outlook. Full filing body not analyzed; description inferred from form + item codes. PMs should watch for datacom transceiver revenue trends, AI-driven 800G/1.6T demand signals, and any guidance revision on margins or the compound-semiconductor segment.
