    Coherent Investment Narrative Recap

    To own Coherent, you need to believe its role as an enabler of AI datacenters, advanced optics and power electronics can support profitable growth despite cyclicality and capital intensity. The new 300mm silicon carbide platform clearly reinforces the AI and electrification catalyst, but it does not remove key risks around heavy manufacturing investment, demand volatility in silicon carbide and exposure to aggressive pricing in optical components.

    The 300mm SiC milestone sits alongside Coherent’s earlier collaboration with NVIDIA on silicon photonics networking for AI datacenter connectivity, underscoring how the company is positioning itself inside the AI infrastructure stack at both the compute and power levels. Together, these moves concentrate the short term catalyst around AI and cloud spending, while heightening the importance of managing capital spend and customer concentration as this exposure grows.

    Yet investors should also weigh how heavy manufacturing commitments could amplify any future downturn in silicon carbide demand...
