Item 1.01. Entry into a Material Definitive Agreement.

On June 30, 2026, Frontier Airlines, Inc. (“Frontier”), a wholly owned subsidiary of Frontier Group Holdings, Inc. (the “Company”), entered into an agreement with Avolon Leasing Ireland 3 Limited (“Avolon”), an existing lessor, to sell 11 A321neo aircraft at the time of delivery from the Company's existing purchase commitment. The 11 aircraft include 3 deliveries expected in the fourth quarter of 2026 and 8 deliveries anticipated in the first half of 2027 based on the current delivery dates as of the filing date of this Current Report on Form 8-K. As previously disclosed on May 5, 2026 as a non-binding agreement in principle, this transaction is part of the Company's fleet-rightsizing initiative to increase the productivity of the airline. The aircraft are being sold at current market rates factoring in transition-related costs, including estimated remarketing costs, and each aircraft will be sold at the time of delivery to the Company. Accordingly, the Company now expects to take delivery of 22 aircraft this year, including 8 A320neo aircraft and 14 A321neo aircraft, with 3 of the A321neo aircraft expected to be sold in the fourth quarter as part of this transaction, and to exit 2026 with a fleet of 171 aircraft.

The preceding description is qualified in its entirety by reference to the full text of the agreement, a copy of which the Company intends to file as an exhibit to its Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2026.
