Frontier Group Holdings, Inc.

Our sustainability pillars are a key part of our business. First, by focusing on responsible business practices and financial investments that reduce our environmental footprint, we have maintained our status as America’s Greenest Airline when measured by available seat miles (“ASMs”) per fuel gallon consumed during the year ended December 31, 2025 as compared to all other major U.S. carriers. We believe we are leading the way in sustainability in the airline industry and serving the needs of a growing community of eco-conscious air travelers. Second, we believe that air travel should be accessible to all and we aim to place people—both our customers and team members—first. Not only do we believe we have a highly engaged and satisfied workforce, we also partner with mentoring and professional development organizations to foster opportunities for those pursuing aviation careers from all backgrounds. Third, we take pride in supporting our communities through various philanthropic and volunteer initiatives. Finally, we aim for the well-being of our customers and team members in everything we do, and we believe we are an industry leader in safe practices.

Recognizing its importance, the Board and its committees provide sustainability guidance and oversight to management. The Nominating and Corporate Governance Committee is responsible for the review of our sustainability strategy and practices and periodically reports on these matters to the Board. The Audit Committee is responsible for the oversight of any related risks having a possible effect on the integrity of financial reporting which are also reported to the Board, as necessary. The Compensation Committee is responsible for human capital management oversight and periodic reviews over workplace environment and culture. The Safety and Security Committee is responsible for oversight, including compliance and evaluation, of programs related to our safety performance and physical security. Moreover, any pertinent feedback that management receives from stockholders as part of our regularly scheduled stockholder engagement practices is reported to the Board for its consideration.
