Ryanair issued a $194.3 million US Export Import Bank prefunded guaranteed bond at the lowest spread for such a financing to date.
The bond priced at mid-swaps plus 65 basis points for a coupon of 1.741%.
The transaction was "over three times oversubscribed", according to Citi, which along with BNP Paribas acted as bookrunners on the deal.
The use of proceeds will be to finance seven new Boeing 737-800 aircraft scheduled for delivery from September through December.
Portmarnock Leasing is the issuer of the financing.
