Spirit Airlines announced that it would enter into discussions with JetBlue in respect to JetBlue’s unsolicited proposal to buy the low-cost carrier. In a statement, the airline said that its board of directors had determined that the JetBlue offer to acquire Spirit in an all-cash transaction for $33 a share could reasonably likely be seen to lead to a “superior proposal” as defined in Spirit’s merger agreement with Frontier Group Holdings, parent company of Frontier Airlines. Spirit, said the statement, remains bound by the terms of the merger agreement with Frontier, and Spirit's board has not determined that JetBlue's proposal in fact constitutes a “superior proposal” as defined in the merger agreement with Frontier. In addition, Spirit noted that there can be no assurance that the discussions with JetBlue will result in a transaction. Spirit shareholders, said the statement, do not need to take any action at this time, and Spirit's board has made no change to its recommendation that its shareholders adopt the merger agreement with Frontier.
