However, Coherent's story also depends on healthy datacom demand and smooth co packaged optics adoption, and any slip in these areas could quickly weaken this upbeat narrative.

Another View On Coherent Using Earnings Multiples

The narrative fair value model flags Coherent as undervalued, yet the current P/E of 73.1x tells a different story. That is higher than the US Electronic industry at 30.7x and only slightly below the peer average of 74.9x, and it is also above the fair ratio of 71.8x.

This gap suggests limited room for further rerating on earnings alone unless the market moves closer to that fair ratio. It raises a simple question for investors: Is the current price already baking in much of the AI optimism, or is there still enough margin of safety in this story to stay comfortable with that earnings multiple?
