Insights

Capital markets and credit analyst

Refinancing extends maturities and may lower interest on 2028 debt.

Danaos issued $500 million in senior notes at 6.875%, maturing in 2032, with cash interest due each March 1 and September 1 starting March 1, 2026. The filing lists specific uses: full redemption of the $262.8 million 8.500% notes due 2028, and full repayment of the $130 million BNP/Crédit Agricole and $55.25 million Alpha Bank secured facilities on December 1, 2025, plus transaction costs and general purposes.

This sequence consolidates debt under a longer-dated unsecured instrument and schedules a 2028 notes redemption “on or about” March 1, 2026. The coupon on the new notes is below the redeemed notes’ coupon, which may reduce interest expense on that tranche after redemption. Near term, activity will depend on executing the listed repayments and redemption steps as dated.
