## Summary
- Charter (~21% of CSG revenue) extends contract through Dec 31, 2027, effective Jan 1, 2022.
- Charter migrated ~300k and ~800k accounts to CSG's ACP in Q2 and Q3 2021; remaining in 12-18 months.
- Modified pricing with minimum commitment; true-up payable if not met by Dec 2027.

- Amendment not expected to materially impact 2021 results; long-term revenue depends on conversion timing.
