STACK GEN03 is a separate proposed wholesale campus near Geneva, not part of the Vaultica GEN02 operating record. The current 12 MW boundary is future potential: Knight Frank reported the committed Geneva pipeline as fully pre-leased but said GEN03 had not broken ground by year-end 2025. Customer utilization, private contract terms and unreported project financing remain outside the verified public record.
