# ADTRAN amends credit facility, adds $100M subline for German unit, relaxes cash covenant

## Summary
- Created a $100M subline under existing $400M revolver for German subsidiary Adtran Networks SE.
- German borrower can draw up to $75M initially; prepayment below threshold triggers permanent commitment reduction.
- Waived prior requirement for German entities to guarantee entire credit; now guarantee only the subline.
- Reduced minimum unrestricted cash covenant from $75M to $70M during Springing Covenant or Covenant Relief Periods.
- Total revolving commitments unchanged at $400M; US borrower retains $300M availability plus $50M term loan.
