The realistic upside is a strong but bounded
rerating. Coherent already has proof of demand, a much better balance-sheet setup after the NVIDIA placement, and clear share-gain vectors in
800G,
1.6T,
OCS, and eventually
CPO. That supports sustained double-digit revenue growth and better margins, but its industrial mix, customer concentration, and hardware cyclicality argue against an open-ended hypergrowth multiple.
