Our interpretation
Production is stronger evidence than a roadmap. Generation-specific output, yields and customer allocation determine whether capacity remains constrained.
What to monitor

- Capital spending versus cash generation
What would weaken the case?
- Qualified supply catches up with demand
- Pricing or inventory indicates easing constraints
Economic exposure
Revenue tied to this specific constraint, pricing power and current valuation have not been quantified in this profile. These need a separate financial review.
