Coherent (COHR) is back in focus after high profile product showcases at OFC 2026 and an expanded multiyear partnership with Nvidia, including a sizeable investment and a long term AI photonics supply commitment.

The recent Nvidia partnership and OFC 2026 showcases come after a powerful run, with a 30.52% year to date share price return and a very large 1 year total shareholder return. This hints that investors see rising potential in Coherent’s AI photonics role despite a 7.96% one day pullback.

With Coherent at US$253.63 after a strong multi year share price move, rapid revenue and net income growth, and Nvidia’s US$2b tie up, you have to ask: is there still upside on the table, or is the AI photonics story already fully priced in?

Most Popular Narrative: 3.2% Overvalued

According to Vestra, the most followed narrative pegs Coherent’s fair value at $245.70, slightly below the latest $253.63 close, framing the stock as fully priced.

The fair value for Coherent Corp. (COHR) is calculated using my fair value method by applying a 32.5x Forward P/E multiple to the 2027 projected EPS of $7.56, reflecting its superior growth profile relative to traditional hardware peers. This results in a fair value of $245.70 in local currency (USD).

Curious what earnings power has to look like to support that 32.5x multiple, the revenue mix shift toward AI optics, and the margin profile this narrative leans on.

Result: Fair Value of $245.70 (OVERVALUED)

However, this hinges on flawless execution. Delays in Indium Phosphide expansion or weaker than expected 1.6T transceiver uptake could quickly challenge that fully priced narrative.
