Spirit Airlines, Inc. (NYSE: SAVE)(“Spirit”) ”) today announced that it has commenced an underwritten public offering of 12,000,000 shares of its common stock (the “Common Stock Offering”) and an underwritten public offering of $150,000,000 aggregate principal amount of convertible senior notes due 2025 (the “Convertible Notes” and such offering, the “Convertible Notes Offering”).

Spirit intends to grant the underwriters a 30-day option to purchase up to 1,800,000 additional shares of common stock in the Common Stock Offering and a 30-day option to purchase up to $22,500,000 aggregate principal amount of additional Convertible Notes, solely to cover over-allotments, in the Convertible Notes Offering.
