- Revolver maturity extended to five years; prior $328 million term loans retired.
- Key covenants eased—no minimum interest-coverage test and fewer limits on dividends or share repurchases.
- Pricing set at Term SOFR + 1.125%–1.625% (or Base Rate + 0.125%–0.625%), scaled to leverage and credit rating.
