Bottom line
The sleeper story here is that Corning's celebrated carrier 'recovery' is a mirage: AT&T and Lumen agreements worth $2B+ are pre-orders for 2025-2026 capacity, not current demand, while actual carrier sales metrics mysteriously disappeared from disclosure. The 55% AI-driven Enterprise growth grabs headlines but management's confidence is crumbling, pushing off guidance updates while refusing to discuss customer concentration in what's clearly a hyperscaler-dependent boom. The binding constraint isn't demand but disclosure quality: they're running out of ways to hide that both major growth drivers are built on shaky foundations. Wendell said it best while dodging a sustainability question: 'We'll update with our latest architectural thoughts.' My view changes if they provide Enterprise customer concentration metrics showing less than 50% from top three customers.

The 30-second version

  • Carrier fiber spring may be false dawn: AT&T/Lumen deals totaling $2B+ mask continued inventory burn
  • Enterprise AI growth at 55% YoY looks unsustainable: customer concentration risk ignored
  • Display pricing power narrative crumbling: double-digit increases still can't offset yen weakness
