Coherent reports quarterly earnings beat on AI datacenter and communications demand; stock up 51.99% over 90 days but valued near analyst fair-value estimates.

Coherent reported quarterly results that topped analyst expectations on revenue and margins, with management citing strong AI datacenter and communications demand and higher capital spending.

The stock has gained 18.24% over the past 30 days and 51.99% over 90 days, reflecting AI datacenter demand and NVIDIA's stake shifting expectations around growth and risk.

The most followed valuation narrative puts fair value at $371, slightly below the last close at $380.18, framing the stock as 2% overvalued and pricing in a premium for its AI and optics opportunity. A DCF analysis suggests the stock trades above an estimated future cash flow value of $296.66, though on a P/S ratio of 11.3x versus a fair ratio of 12.8x the stock appears more reasonable.

The narrative depends on rapid revenue expansion, higher margins, and a rich future earnings multiple, but faces risks from rising competition and large capital projects such as indium phosphide capacity that could squeeze margins and delay the earnings ramp.
