Does Coherent's Valuation Leave Enough Room for Upside?

Coherent COHR offers investors a compelling growth story, but its valuation makes the entry point important. Based on fiscal 2026 results, the stock trades above 40 times EBITDA and above 60 times adjusted earnings, levels that leave little room for operational disappointment.

Those multiples could decline rapidly if Coherent delivers the growth currently anticipated. First-quarter guidance indicates roughly 50% year-over-year revenue growth and a 70% increase in non-GAAP earnings per share. Full-year consensus projections of $9.46 per share in earnings and approximately $2.8 billion in EBITDA would lower the valuation to about 36 times earnings and 25 times EV/EBITDA.

The central question is how long exceptional datacom demand can continue. Coherent’s backlog extends into fiscal 2028, making manufacturing capacity and production ramps the primary near-term constraints. However, supply should eventually catch up with demand, potentially slowing revenue growth and pressuring the premium investors assign to the shares.

Margin expansion may provide some support, though the opportunity appears measured. Fiscal 2026 adjusted gross margin improved 152 basis points to 39.4%, while management continues to target more than 42%. Greater internal production of indium phosphide lasers could help, but rising transceiver sales carry relatively lower margins. With adjusted operating margin already near 20%, revenue growth will likely remain the dominant earnings driver.

COHR’s Peer Landscape

Lumentum Holdings LITE and Fabrinet FN provide useful comparisons within the optical communications ecosystem. Lumentum is exposed to similar AI-driven networking demand, while Fabrinet benefits from increased manufacturing requirements across optical products. Investors comparing Coherent with Lumentum should assess differences in product exposure and profitability. Likewise, Fabrinet offers another perspective on how capacity expansion converts into earnings. Ultimately, Lumentum and Fabrinet reinforce that execution, margins and demand durability matter alongside headline growth.

COHR appears attractive for long-term AI infrastructure believers, but its valuation and volatility favor a disciplined entry price.
