Done! I've built the FY2025 revenue bridge for InterStationary and written the commentary note. Here's what the analysis shows:

**Key findings:**
- Revenue remained essentially flat at $11.2M (down just $5K or 0.04%)
- The portfolio experienced significant churn: 4 customer losses totaling $1.3M, plus 11 declines totaling $443K
- This was offset by 23 upselling opportunities ($1.2M) and 6 new customers ($463K), with notable wins from Harbor Freight Partners ($148K), Ember Analytics ($136K), and Alder Logistics ($126K)
- The biggest losses were Fenwick Legal ($686K), Birchway Foods ($503K), and Driftwood Media ($113K decline)
