Bottom line
The sleeper story is that Corning just locked up the AI infrastructure market with $18B+ in Meta-style agreements, essentially recreating their display monopoly in optical. The market sees the Springboard upgrade to $11B as huge, but it's actually conservative given they haven't included most of these deals or any scale-up revenue. The binding constraint isn't demand, it's their willingness to share risk: 'We look to customers to derisk any investments.' Watch for solar to stay dilutive way longer than guided. My view changes if enterprise growth reaccelerates above 30% in Q1 proving capacity additions are working.

The 30-second version

  • The sleeper: Meta deal structure reveals Corning is becoming an infrastructure monopoly, not just a supplier
  • The obvious: Springboard upgrade to $11B looks massive but it's actually conservative
  • The red flag: Solar ramp is eating $0.03-0.05 EPS quarterly with no clear end date
