Coherent (COHR) Could Be 25% Undervalued Following AI Demand And Earnings Strength

Simply Wall St·10/10/2026 16:40:46
Listen to the news

Coherent (COHR) is back in focus after sharp swings tied to AI infrastructure expectations, strong recent earnings and revenue growth, and fresh worries about rising Treasury yields affecting high-multiple tech stocks.

Against this choppy backdrop, Coherent’s share price has swung between profit taking and renewed enthusiasm around AI spending. It still carries a year to date share price return of 60.87% and a 1 year total shareholder return of 181.39%, signalling momentum that has cooled in recent weeks rather than fully reversed.

Capitalize on the AI optics story driving Coherent by scanning a hand picked set of 92 AI infrastructure stocks aligned with surging data center investment.

Coherent has already delivered huge gains on the AI optics story, yet the recent pullback and rich expectations leave a simple puzzle. Is the real upside still in front of investors, or mostly in the rearview mirror as valuation stretches?

Most Popular Narrative: 25% Undervalued

On the most followed view of Coherent, a fair value of $415.36 sits well above the last close at $312.62, and that gap only makes sense if the AI datacenter story and margin uplift play out as modeled.

The ongoing expansion of AI datacenter infrastructure and high-performance computing is propelling structural growth in demand for advanced optical transceivers (800G, 1.6T, and beyond), optical circuit switches, and related photonics components, which is fueling robust sequential order growth and sustained revenue momentum in Coherent's datacom and communications business.

See why 117 investors see Coherent as 25% undervalued.

Result: Fair Value of $415.36 (UNDERVALUED)

Still, Coherent’s reliance on a handful of large customers, along with the heavy capital needed for new fabs, could quickly pressure the story if demand expectations reset.

Another View: What Coherent’s P/E Is Telling You

Those fair value models paint Coherent as about 25% undervalued, yet the simple P/E picture is tougher. The stock trades on roughly 79.5x earnings versus a fair ratio of 71.9x, the US Electronic industry at 30.3x, and peers at 43.5x. That gap points to real valuation risk if sentiment cools.
