Coherent Investment Narrative Recap

To own Coherent, you really have to believe that AI data center and high speed optics demand will remain strong enough to justify its heavy manufacturing build out and recent valuation. The latest quarter’s return to solid profitability, together with above consensus revenue guidance, reinforces that AI driven optics is still the key near term catalyst, while the biggest risk remains whether those capital intensive capacity additions ultimately earn attractive returns or leave the company more exposed if demand normalizes.

The most relevant recent development is Coherent’s first quarter Fiscal 2027 revenue guidance of US$2.2 billion to US$2.4 billion, which directly ties into the AI optics thesis by pointing to continued strength in data center and communications demand. That outlook, supported by expanded 6 inch indium phosphide capacity, now sits alongside earlier concerns about competition, capital intensity and customer concentration, and may prompt some investors to reassess how they weigh those risks against the AI driven growth story.

Yet despite this strong print and upbeat outlook, investors should still be aware of how dependent Coherent’s thesis is on continued AI data center spending...

Coherent's narrative projects $15.3 billion revenue and $2.7 billion earnings by 2029. This requires 32.3% yearly revenue growth and an earnings increase of about $2.3 billion from $400.6 million today.

Uncover how Coherent's forecasts yield a $394.62 fair value, a 21% upside to its current price.

Exploring Other Perspectives

Before this report, the most optimistic analysts were assuming Coherent could reach about US$15.9 billion in revenue and US$2.9 billion in earnings by 2029, which is a far more aggressive AI optics driven scenario than the baseline consensus and makes execution risks around the 6 inch indium phosphide ramp even more important to think through in light of these new results.
