Lumentum’s# laser supply crunch is getting worse.
In April, CEO Michael Hurlston told Bloomberg that products were essentially sold out through 2027, despite capacity expansion in Japan and a new U.S. wafer fab acquisition.
Six months later, the outlook is even tighter:
• Some products are shipping 30% below demand.
• Shortages could extend into 2028.
• 2029 capacity is already nearly sold out.
• Another product category could face a 70% supply shortfall next year.
The real bottleneck isn’t demand. It’s laser wafer fab capacity.
In just six months, the sold-out horizon has shifted from 2027 to 2029.
AI infrastructure is expanding faster than the optical supply chain can keep up.
