Spirit Airlines, Inc. (NYSE: SAVE) ("Spirit") today announced that it has commenced an underwritten public offering of $440,000,000 aggregate principal amount of convertible senior notes due 2026 (the "Convertible Notes" and such offering, the "Convertible Notes Offering"). Spirit intends to grant the underwriters of the Convertible Notes Offering a 30-day option to purchase up to $60,000,000 aggregate principal amount of additional Convertible Notes, solely to cover over-allotments, in the Convertible Notes Offering.

Spirit is also separately conducting a registered direct offering of shares of its common stock (the "Common Stock Offering") to certain holders of its outstanding 4.75% Convertible Senior Notes due 2025 (the "2025 Convertible Notes").

Spirit expects to use a portion of the net proceeds from the Convertible Notes Offering to repurchase a portion of its outstanding 4.75% Convertible Senior Notes due 2025 (the "2025 Convertible Notes") for cash pursuant to privately negotiated agreements with a limited number of current holders of such 2025 Convertible Notes, which agreements are conditioned upon the consummation of the Convertible Notes Offering. Spirit expects to use any remaining net proceeds from the Convertible Notes Offering for general corporate purposes. Spirit expects to use the net proceeds from the Common Stock Offering to redeem up to 40% of the original outstanding principal amount, or up to $340 million, of its 8.00% Senior Secured Notes due 2025 at a redemption price equal to 108.0%, plus accrued and unpaid interest on the principal amount being redeemed up to, but excluding, the redemption date.

The closing of neither the Common Stock Offering nor the Convertible Notes Offering is conditioned upon the closing of the other offering.
