**NOTICE OF ANNUAL MEETING OF STOCKHOLDERS**

**To be Held on May 14, 2026**

To Our Stockholders:

The 2026 annual meeting of stockholders (the "Annual Meeting") of Frontier Group Holdings, Inc., a Delaware corporation (the "Company"), will be held virtually on May 14, 2026, at 9:30 a.m. Mountain Daylight Time. You will be able to attend the Annual Meeting online and submit your questions during the Annual Meeting by visiting www.virtualshareholdermeeting.com/ULCC2026 and entering the 16-digit control number included on the Notice of Internet Availability of Proxy Materials (the "Internet Notice") or any proxy card that you received, or on the materials provided by your bank or broker. You will also be able to submit questions in advance of the Annual Meeting by visiting www.proxyvote.com. The Annual Meeting will be held for the following purposes:

(1)To elect Andrew S. Broderick, Bernard L. Han, Anthony D. Salcido, and Alejandro D. Wolff, as Class II directors to serve until the 2029 annual meeting of stockholders, and until their respective successors are duly elected and qualified;

(2)To ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026; and

(3)To approve, on an advisory (non-binding) basis, the compensation of our named executive officers.

The stockholders will also act on any other business that may properly come before the Annual Meeting or any postponement, continuation, or adjournment thereof.

While all of the Company's stockholders are invited to attend the virtual Annual Meeting, only holders of record of our outstanding shares of common stock at the close of business on March 27, 2026 are entitled to notice of and to vote at the Annual Meeting, or any continuation, postponement, or adjournment of the Annual Meeting. A complete list of these stockholders will be available for examination by any stockholder during the ten days prior to the Annual Meeting for a purpose germane to the Annual Meeting by sending an email to IR@flyfrontier.com, stating the purpose of the request, and providing proof of ownership of the Company's common stock. The Annual Meeting may be continued or adjourned from time to time without notice other than by announcement at the Annual Meeting.

**Important Information for Holders of Common Stock**

It is important that your shares be represented regardless of the number of shares you may hold as of the record date. Whether or not you plan to attend the virtual Annual Meeting, we urge you to vote your shares via the toll-free telephone number or over the Internet, as described in the enclosed materials. If you received a copy of the proxy card by mail, you may sign, date, and mail the proxy card in the enclosed return envelope, which is addressed for your convenience and needs no postage if mailed in the United States. Promptly voting your shares will ensure the presence of a quorum at the Annual Meeting and will save us the expense of further solicitation. Submitting your proxy now will not prevent you from voting your shares at the Annual Meeting if you desire to do so, as your proxy is revocable at your option. The Company asks your cooperation in promptly submitting your proxy.

**YOUR VOTE IS IMPORTANT**

If you would like to attend the virtual Annual Meeting, please refer to the logistical information in the section titled "Questions and Answers About the 2026 Annual Meeting of Stockholders."

By Order of the Board of Directors,

**QUESTIONS AND ANSWERS ABOUT THE 2026 ANNUAL MEETING OF STOCKHOLDERS**

**WHO IS ENTITLED TO VOTE AT THE ANNUAL MEETING?**

The Record Date for the Annual Meeting is March 27, 2026. You are entitled to vote at the Annual Meeting only if you are a stockholder of record at the close of business on that date, or if you hold a valid proxy for the Annual Meeting. Each share of our common stock entitles its holder to one vote per share on all matters presented to our stockholders. Stockholders are not permitted to cumulate votes with respect to the election of directors. At the close of business on March 27, 2026, there were 229,732,124 shares of our common stock issued and outstanding and entitled to vote at the Annual Meeting.

Notwithstanding the foregoing, to comply with restrictions imposed by federal law on foreign ownership and control of U.S. airlines, our amended and restated certificate of incorporation and amended and restated bylaws (the "Bylaws") restrict ownership, voting, and control of shares of our capital stock by non-U.S. citizens. The restrictions imposed by U.S. federal law and U.S. Department of Transportation (the "DOT") policy require, among other things, that no more than 25% of our issued and outstanding voting stock be owned or controlled, directly or indirectly, by persons or entities who are not U.S. citizens, as defined in 49 U.S.C. § 40102(a)(15) (the "Voting Limitation"). In order to comply with these restrictions, we maintain a "Foreign Stock Record" to track the registration of shares of our voting stock held by non-U.S. citizens. Shares of our voting stock held by non-U.S. citizens may not be voted at the Annual Meeting unless such shares are registered on the Foreign Stock Record. If at any time we determine that the number of shares of our voting stock purportedly registered on the Foreign Stock Record exceeds the Voting Limitation, our Bylaws provide for the suspension of the voting rights of such shares in reverse chronological order, based upon the date of registration in the Foreign Stock Record, to the extent required to ensure that we are in compliance with the Voting Limitation.

**WHY HAVE I RECEIVED A "NOTICE OF INTERNET AVAILABILITY OF PROXY MATERIALS"?**

As permitted by the rules of the U.S. Securities and Exchange Commission (the "SEC"), we are making this proxy statement and our 2025 Annual Report available to certain of our stockholders electronically via the Internet. On or about April 2, 2026, we mailed to these stockholders an Internet Notice containing instructions on how to access this proxy statement and our 2025 Annual Report and vote online. If you received an Internet Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them. Instead, the Internet Notice instructs you on how to access and review all of the important information contained in the proxy statement and 2025 Annual Report. The Internet Notice also instructs you on how you may submit your proxy over the Internet. If you received an Internet Notice by mail and would like to receive a printed copy of our proxy materials, then you should follow the instructions for requesting such materials contained on the Internet Notice.

**WHAT IS THE DIFFERENCE BETWEEN BEING A "RECORD HOLDER" AND HOLDING SHARES IN "STREET NAME"?**

A record holder holds shares in his or her name. Shares held in "street name" means shares that are held in the name of a bank or broker on a person's behalf.

**AM I ENTITLED TO VOTE IF MY SHARES ARE HELD IN "STREET NAME"?**

Yes. If your shares are held by a bank or a brokerage firm, you are considered the "beneficial owner" of those shares held in "street name." If your shares are held in street name, these proxy materials are being provided to you by your bank or brokerage firm, along with a voting instruction card if you received printed copies of our proxy materials. As the beneficial owner, you have the right to direct your bank or brokerage firm how to vote your shares, and the bank or brokerage firm is required to vote your shares in accordance with your instructions. If your shares are held in "street name," you should contact your broker or other nominee to obtain your 16-digit control number or otherwise vote through the broker or other nominee.

**HOW MANY SHARES MUST BE PRESENT TO HOLD THE ANNUAL MEETING?**

A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting, in person, by remote communication, if applicable, or by proxy, of the holders of a majority of the voting power of all issued and outstanding shares of our capital stock entitled to vote at the Annual Meeting constitutes a quorum for the transaction of business.

**WHO CAN ATTEND AND VOTE AT THE ANNUAL MEETING?**

The Annual Meeting will be held entirely online. Stockholders may participate in the Annual Meeting by visiting the following website: www.virtualshareholdermeeting.com/ULCC2026.

**QUESTIONS AND ANSWERS ABOUT THE 2026 ANNUAL MEETING OF STOCKHOLDERS (continued)**

To participate and vote at the Annual Meeting, you will need the 16-digit control number included on your Internet Notice or your proxy card or on the instructions that accompanied your proxy materials. If your shares are held in "street name," you should contact your broker or other nominee to obtain your 16-digit control number or otherwise vote through the broker or other nominee. You will need to obtain your own Internet access if you choose to attend the Annual Meeting online and/or vote over the Internet. If you lose your 16-digit control number, you may join the Annual Meeting as a "Guest" but you will not be able to vote or ask questions. The Annual Meeting webcast will begin promptly at 9:30 a.m. Mountain Daylight Time. We encourage you to access the Annual Meeting webcast prior to the start time. Online check-in will begin shortly before the meeting time, and you should allow ample time for check-in procedures.

**WHY HOLD A VIRTUAL MEETING?**

A virtual meeting enables increased stockholder attendance and participation because stockholders can participate from any location around the world. You will be able to attend the Annual Meeting online and submit your questions by visiting www.virtualshareholdermeeting.com/ULCC2026. You also will be able to vote your shares electronically at the Annual Meeting by following the instructions below.

**WHAT IF DURING THE CHECK-IN TIME OR DURING THE ANNUAL MEETING I HAVE TECHNICAL DIFFICULTIES OR TROUBLE ACCESSING THE VIRTUAL MEETING WEBSITE?**

We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting website, and the information for assistance will be located on the Annual Meeting login page. You will need to obtain your own Internet access.

**WILL THERE BE A QUESTION AND ANSWER SESSION DURING THE ANNUAL MEETING?**

As part of the Annual Meeting, we will hold a live Q&A session, during which we intend to answer appropriate questions submitted via the virtual meeting platform by stockholders during the Annual Meeting that are pertinent to us and the meeting matters. We will endeavor to answer as many questions submitted by stockholders as time permits. Only stockholders who have accessed the Annual Meeting as a stockholder (rather than a "Guest") by following the procedures outlined above in "Who can attend and vote at the Annual Meeting?" will be permitted to submit questions during the Annual Meeting. Each stockholder is limited to no more than two questions. Questions should be succinct and only cover a single topic. We will not address questions that are, among other things:

• irrelevant to our business or to the business of the Annual Meeting;

• related to material non-public information of the Company, including the status or results of our business since our last earnings release;

• related to any pending, threatened, or ongoing litigation;

• related to personal grievances;

• derogatory references to individuals or that are otherwise in bad taste;

• substantially repetitious of questions already submitted by another stockholder;

• in excess of the two-question limit;

• in furtherance of the stockholder's personal or business interests; or

• out of order or not otherwise suitable for the conduct of the Annual Meeting as determined by the Chairperson or Secretary in their reasonable judgment.

Additional information regarding the Q&A session will be available in the "Rules of Conduct" available on the Annual Meeting website for stockholders that have accessed the Annual Meeting as a stockholder (rather than a "Guest") by following the procedures outlined above in "Who can attend and vote at the Annual Meeting?".

**QUESTIONS AND ANSWERS ABOUT THE 2026 ANNUAL MEETING OF STOCKHOLDERS (continued)**

**WHAT IF A QUORUM IS NOT PRESENT AT THE ANNUAL MEETING?**

If a quorum is not present at the scheduled time of the Annual Meeting, the Chair of the Annual Meeting may adjourn the Annual Meeting until a quorum is present or represented.

**WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE INTERNET NOTICE OR MORE THAN ONE SET OF PROXY MATERIALS?**

It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Internet Notice or set of proxy materials, please submit your proxy by phone, via the Internet or, if you received printed copies of the proxy materials, by signing, dating, and returning the enclosed proxy card in the enclosed envelope.

**HOW CAN I OBTAIN A PAPER COPY OF THE 2025 ANNUAL REPORT?**

We will furnish, without charge, a copy of our 2025 Annual Report, including consolidated financial statements, but not including exhibits, to each of our stockholders of record on March 27, 2026, and to each beneficial stockholder on that date upon written request made to Howard Diamond, Executive Vice President, Legal and Corporate Affairs, Frontier Group Holdings, Inc., 4545 Airport Way, Denver, CO 80239. A reasonable fee will be charged for copies of requested exhibits.

**HOW DO I VOTE?**

We recommend that stockholders vote prior to the Annual Meeting by proxy even if they plan to attend the Annual Meeting and vote during the Annual Meeting. If you are a stockholder of record, there are three ways to vote by proxy:

• **by Internet:** You can vote over the Internet at www.proxyvote.com by following the instructions on the Internet Notice or proxy card.

• **by Telephone:** You can vote by telephone by calling 1-800-690-6903 and following the instructions on the proxy card.

• **by Mail:** You can vote by mail by signing, dating, and mailing the proxy card, which you may have received by mail.

Internet and telephone voting facilities for stockholders of record will be available 24 hours a day and will close at 11:59 p.m. Eastern Daylight Time on May 13, 2026.

If your shares are held in street name through a bank or broker, you will receive instructions on how to vote from the bank or broker. You must follow their instructions in order for your shares to be voted. Internet and telephone voting also may be offered to stockholders owning shares through certain banks and brokers. If your shares are not registered in your own name and you would like to vote your shares at the Annual Meeting, you should contact your bank or broker to obtain your 16-digit control number or otherwise vote through your bank or broker.

**CAN I CHANGE MY VOTE AFTER I SUBMIT MY PROXY?**

Yes.

If you are a registered stockholder, you may revoke your proxy and change your vote:

• by submitting a duly executed proxy bearing a later date;

• by granting a subsequent proxy through the Internet or telephone;

• by giving written notice of revocation to the Corporate Secretary of Frontier Group Holdings, Inc. prior to the Annual Meeting; or

• by voting during the Annual Meeting.

Your most recent proxy card or Internet or telephone proxy is the one that is counted. Your attendance at the Annual Meeting by itself will not revoke your proxy unless you give written notice of revocation to the Corporate Secretary before your proxy is voted or you vote during the Annual Meeting.

If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker, or you may vote during the Annual Meeting by obtaining your 16-digit control number from your bank or broker or otherwise voting through your bank or broker.

**QUESTIONS AND ANSWERS ABOUT THE 2026 ANNUAL MEETING OF STOCKHOLDERS (continued)**

**WHO WILL COUNT THE VOTES?**

A representative of Broadridge Financial Solutions, Inc., our inspector of election, will tabulate and certify the votes.

**WHAT IF I DO NOT SPECIFY HOW MY SHARES ARE TO BE VOTED?**

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board. The Board's recommendations are indicated within the description of each proposal in this proxy statement.

**WILL ANY OTHER BUSINESS BE CONDUCTED AT THE ANNUAL MEETING?**

We know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, however, the proxy holders named on the Company's proxy card will vote your shares in accordance with their best judgment.

**HOW MANY VOTES ARE REQUIRED FOR THE APPROVAL OF THE PROPOSALS TO BE VOTED UPON AND HOW WILL ABSTENTIONS AND BROKER NON-VOTES BE TREATED?**

|:---|:---|:---|
| **Proposal** | **Voting Standard** | **Effect of Votes Withheld/Abstentions and Broker Non-Votes** |
| Proposal No. 1: To elect Andrew S. Broderick, Bernard L. Han, Anthony D. Salcido, and Alejandro D. Wolff as Class II directors to serve until the 2029 annual meeting of stockholders, and until their respective successors are duly elected and qualified | Plurality of votes cast | Votes withheld and broker non-votes will have no effect. |
| Proposal No. 2: To ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026 | Majority of votes present and entitled to vote | Abstentions will be counted as a vote against this proposal. We do not expect any broker non-votes on this proposal. |
| Proposal No. 3: To approve, on an advisory (non-binding) basis, the compensation of our named executive officers | Majority of votes present and entitled to vote | Abstentions will be counted as a vote against this proposal. Broker non-votes will have no effect. |

---

**WHAT IS AN ABSTENTION AND HOW WILL VOTES WITHHELD AND ABSTENTIONS BE TREATED?**

A "vote withheld," in the case of the proposal regarding the election of directors, or an "abstention," in the case of the other proposals to be considered at the Annual Meeting, represents a stockholder's affirmative choice to decline to vote on a proposal. Votes withheld and abstentions are counted as present and entitled to vote for purposes of determining a quorum. Votes withheld will have no effect on the election of directors, and abstentions will be counted as a vote against the other proposals to be considered at the Annual Meeting.

**WHAT ARE BROKER NON-VOTES AND DO THEY COUNT FOR DETERMINING A QUORUM?**

Generally, broker non-votes occur when shares held by a broker in "street name" for a beneficial owner are not voted with respect to a particular proposal because the broker (1) has not received voting instructions from the beneficial owner and (2) lacks discretionary voting power to vote those shares. A broker is entitled to vote shares held for a beneficial owner on routine matters, such as the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm, without instructions from the beneficial owner of those shares. On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on non-routine matters, such as the election of directors and the approval of the compensation of our named executive officers. Broker non-votes count for purposes of determining whether a quorum is present.

**WHERE CAN I FIND THE VOTING RESULTS OF THE ANNUAL MEETING?**

We plan to announce preliminary voting results at the Annual Meeting, and we will report the final results in a Current Report on Form 8-K, which we intend to file with the SEC shortly after the Annual Meeting.

Our Board has nominated Andrew S. Broderick, Bernard L. Han, Anthony D. Salcido, and Alejandro D. Wolff as Class II director nominees for election at the Annual Meeting to hold office until the annual meeting of stockholders to be held in 2029, and until their respective successors are duly elected and qualified.

Our Board unanimously recommends that you vote ***"FOR"*** the election of each of Messrs. Broderick, Han, Salcido, and Wolff.

**Our Board of Directors**

Our business and affairs are managed under the direction of our Board. The number of directors is fixed by our Board, subject to the terms of our Charter and amended and restated bylaws ("Bylaws"). Our Board currently consists of twelve directors. In accordance with our Charter, our Board is divided into three classes with staggered three-year terms. At each annual meeting of stockholders, a class of directors is elected for a three-year term to succeed the directors of the same class whose terms are then expiring. The term of the Class II directors elected at the Annual Meeting will begin at the Annual Meeting and end at our 2029 annual meeting of stockholders, or, if later, when such director's successor has been duly elected and qualified.

The following table provides certain information regarding each of our directors as of April 2, 2026.

We believe variety in the skills, experiences and backgrounds of our directors is important in enabling our Board to best represent the interests of our customers, employees and management. The following matrix provides self-reported information about some of the skills, qualifications, and experiences of each director on our Board. The matrix is not intended to be an exhaustive list of each of our directors' skills, qualifications, or contributions to the Board. In addition, the absence of a particular skill or experience with respect to any of our directors does not mean that the director is unable to contribute to the decision-making process in that area.

**CORPORATE GOVERNANCE**

**Director Independence**

Our Board has undertaken reviews of the independence of each director. The reviews are performed on an annual basis in accordance with our corporate governance policies. Based on information provided by each director concerning his or her background, employment, and affiliations, our Board has determined that Josh T. Connor, Robert J. Genise, Bernard L. Han, Ofelia Kumpf, Nancy L. Lipson, Patricia Salas Pineda, Anthony D. Salcido, and Alejandro D. Wolff each qualify as an independent director in accordance with the rules and regulations of The Nasdaq Stock Market LLC (the "Nasdaq Rules"). Under the Nasdaq Rules, the definition of independence includes a series of objective tests, such as that the director is not, and has not been for at least three years, one of our employees and that neither the director nor any of his or her family members has engaged in various types of business dealings with us. Our Board has made a determination as to each independent director that no relationships exist that, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Mr. Dempsey is not considered independent by virtue of his position as our Chief Executive Officer, and Messrs. W. Franke, Broderick and B. Franke are not presently considered independent by virtue of their affiliation with Indigo Partners, to which we pay a quarterly fee for management services. In making these determinations, our Board reviewed and discussed information provided by the directors and us with regard to each director's relationships as they may relate to us and our management, including the beneficial ownership of our capital stock by each director, and the transactions involving them described in the section titled "Certain Relationships and Related Party Transactions."

**Leadership Structure**

We have historically separated the roles of Chief Executive Officer and Chair of the Board in recognition of the differences between the two roles. The Chief Executive Officer is responsible for setting our strategic direction and our day-to-day leadership and performance, while the Chair of the Board provides guidance to the Chief Executive Officer, sets the agenda for Board meetings, and presides over meetings of the full Board. Our Corporate Governance Guidelines provide that whenever the Chair of the Board is a member of management or does not otherwise qualify as an independent director, the independent directors may appoint a lead independent director. Mr. Genise currently serves as our lead independent director. As lead independent director, Mr. Genise calls meetings of the independent directors and establishes the agenda for such meetings, coordinates the activities of, and discussions with, the other independent directors, briefs the Chief Executive Officer on issues arising from executive sessions of the independent directors, and collaborates with the Chair of the Board to establish the agenda for regular meetings of the full Board. Our Board currently believes that our existing leadership structure is effective and will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate.

**Classified Board of Directors**

In accordance with our amended and restated certificate of incorporation, our Board is divided into three classes with staggered three-year terms. At each annual general meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. Our directors are divided among the three classes as follows:

• the Class I directors are William A. Franke, Josh T. Connor, Nancy L. Lipson and Patricia Salas Pineda, and their terms will expire at the annual meeting of stockholders to be held in 2028;

• the Class II directors are Andrew S. Broderick, Bernard L. Han, Anthony D. Salcido and Alejandro D. Wolff, and their terms expire at this Annual Meeting; and

• the Class III directors are James G. Dempsey, Brian H. Franke, Robert J. Genise and Ofelia Kumpf, and their terms will expire at the annual meeting of stockholders to be held in 2027.

We expect that any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. The division of our Board into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control.

**CORPORATE GOVERNANCE (continued)**

**Role of the Board of Directors in Risk Oversight Process**

Risk assessment and oversight are an integral part of our governance and management processes. Our Board encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management and the Audit Committee review these risks with the Board at regular board meetings as part of management presentations that focus on particular business functions, operations, or strategies, and present the steps taken by management to mitigate or eliminate such risks.

Our Board administers this oversight function directly, as well as through various standing committees of our Board that address risks inherent in their respective areas of oversight. While our Board is responsible for monitoring and assessing strategic risk exposure, our Audit Committee is responsible for overseeing our significant financial and operational risk exposures and the actions our management has taken to limit, monitor, and control these exposures, including with respect to cybersecurity, and procedures regarding disaster recovery and critical business continuity. The Audit Committee also approves or disapproves any related party transactions. Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance guidelines. Our Compensation Committee oversees risks related to our executive compensation, equity incentive plans, and other compensatory arrangements. Our Safety and Security Committee oversees risks related to our physical safety and security programs, policies and procedures.

**Meetings of the Board of Directors and Attendance**

Members of our Board are expected to regularly prepare for and attend meetings of the Board and committees on which they sit. A director who is unable to attend a meeting of the Board or a committee of the Board is expected to notify our Chief Executive Officer or the Chair of the appropriate committee in advance of such meeting, and, whenever possible, participate in such meeting via teleconference in the case of an in-person meeting. Our Board met nine times during the fiscal year ended December 31, 2025. During 2025, each director attended at least 75% of the aggregate of the total number of Board meetings and meetings of each committee on which he or she then served, with nine directors in attendance at the 2025 annual meeting of stockholders. Members of our Board are encouraged to attend annual meetings of stockholders; however, we do not maintain a formal policy regarding director attendance at annual meetings.

**Executive Sessions**

The independent members of the Board meet in regularly scheduled executive sessions.

**Committees of the Board of Directors**

Our Board has established an Audit Committee, a Compensation Committee, a Finance Committee, a Nominating and Corporate Governance Committee, and a Safety and Security Committee.

**SUSTAINABILITY, COMMUNITY ENGAGEMENT AND EMPLOYEE BENEFITS**

**Our Commitment**

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.

**Environmental Stewardship**

**Initiatives to reduce aircraft weight, save fuel and benefit the environment**

Our fleet is currently made up exclusively of the Airbus series of single-aisle aircraft, including the A320ceo, A320neo, A321ceo and A321neo aircraft (the "A320 family"). As of December 31, 2025, the average aircraft age of our fleet was approximately five years and 85% of our planes were A320neo family aircraft, which are expected to reduce fuel consumption by 20% and emit lower CO2 emissions compared to the prior generation of A320ceo family aircraft, as well as a 50% reduction in noise. Our fleet continues to be the most fuel-efficient of all major U.S. carriers when measured by ASMs per fuel gallon consumed, generating 106 ASMs per gallon during the year ended December 31, 2025.

We have undertaken multiple initiatives in recent years to reduce the weight of our aircraft, minimize the use of paper in-flight, and increase the use of environmentally friendly products. Flying lighter aircraft saves fuel and reduces CO2 emissions, which not only helps minimize our environmental footprint, but also helps reduce costs, ultimately benefiting consumers in the form of lower fares. A key driver of reduced weight on our aircraft stems from our policies around baggage and in-flight catering. By charging for carry-on and checked bags, consumers are incentivized to pack less. By charging for all food items and beverages, including soft drinks, passengers are encouraged to be more discerning in their consumption, which results in fewer catering supplies and also reduces aircraft weight. We are also focused on reducing the weight of our aircraft seating through adoption of the latest generation of lightweight seats. Current aircraft deliveries are equipped with Recaro seats providing a weight reduction of 6 pounds per seat versus the previous generation. In addition, we have selected Geven seats for future deliveries, which will be approximately 2 pounds lighter than the Recaro seats, further reducing aircraft weight and fuel burn.

Furthermore, as part of our efforts to decarbonize air transportation, we, along with a consortium of other airlines, executed an agreement with CycloKinetics, Inc. in May 2023, with a potential right to purchase domestic Sustainable Aviation Fuel ("SAF") from CycloKinetics, Inc. once it achieves commercial production.

In addition, our headquarters are located in a LEED-certified building, which was designed to achieve energy savings, water efficiency, and lower CO2 emissions.

**ENVIRONMENTAL, SOCIAL, AND GOVERNANCE MATTERS (continued)**

**Other 'green' measures implemented onboard our aircraft:**

• enhanced route planning software, which contributes to fuel efficiency by allowing us to focus on direct, non-stop flights and carry only fuel necessary for the flight;

• removal of in-flight entertainment devices since the vast majority of Americans travel with a personal mobile device containing their preferred entertainment choices, thereby further reducing aircraft weight;

• launch of a mobile app that gives customers access to everything they need electronically, minimizing paper itineraries, receipts, and boarding passes;

• introduction of biodegradable cups and elimination of plastic stirrers;

• creation of paperless cockpits by giving our pilots mobile work pads that contain all the necessary data and information to do their jobs;

• introduction of electronic Flight Attendant Manuals, enabling our flight attendants to use their mobile FlyTab devices for required information and eliminating paper manuals onboard;

• elimination of onboard magazines, resulting in a significant weight reduction per flight while saving thousands of pounds of paper on an annual basis;

• single engine taxi for takeoff and landing when appropriate, among other operating efficiencies, which reduces fuel consumption; and

• more efficient aircraft brakes, which contribute to fuel savings.

**Highlighting endangered species**

Throughout Frontier's history, our airplane tails have featured animals, from Flo the Flamingo and Powder the Polar Bear to Peachy the Fox and Otto the Owl, among hundreds of others. These animals provide our planes with a distinctive and fun appearance that delights children and adults alike. Flight crews on each aircraft hand out trading cards to children onboard that tell the unique story of the animal on the plane's tail. Since 2019, we have highlighted endangered species on our tails, starting with Wellington the Black-Footed Ferret. New tails now feature North American endangered species, serving to highlight the importance of these unique animals whose populations are at risk of extinction. While working to reduce our carbon footprint, we also hope to educate the public and bring awareness to the incredible animals that call the oceans, forests, and plains home.

**Community Engagement**

**Social responsibility**

The Frontier business model is based on the principle that flying should be affordable for everyone. Not only does our pricing structure support that mission, but Frontier's family focus, including our unique *Kids Fly Free* program (with *Discount Den* membership), makes air travel more accessible for families.

When it comes to charitable initiatives, giving back is in our DNA. We support an array of charitable organizations through volunteerism, in-kind donations, and fundraising, with causes ranging from food banks, children, domestic abuse and violence, homelessness, the environment, animals, and terminal illness. For employees experiencing hardship, our HOPE League is available to support and is funded through employee donations.

**ENVIRONMENTAL, SOCIAL, AND GOVERNANCE MATTERS (continued)**

**Health, Safety, and Well-being**

**Compensation and Benefits**

We design our compensation and benefits with the goal of supporting the financial, mental, and physical well-being of our employees and their families. We evaluate our benefit programs each year in terms of value of benefit offerings and out-of-pocket costs so that they are competitive with the benefit offerings of other companies with whom we compete for talent. We continuously evaluate our benefit offerings through these market studies as well as annual employee surveys. In 2026, we began using Cigna Healthcare as our medical insurance provider. Through Cigna Healthcare, we offer the Wellness Done Right program which incentivizes participating employees to invest in their health by providing discounts on medical insurance premiums for completing certain preventative care activities. Through Cigna Healthcare, we also offer our employees Active and Fit, which provides access to gyms nationwide as well as digital fitness programs, and Cigna Lifestyle Management Program, a lifestyle and weight management program, and employees can also access Maven, an educational and financial resource for navigating the different paths to parenthood.

**Safety and Security**

We prioritize the safety and security of our passengers and employees. Some of the safety and security measures we have taken include: aircraft security and surveillance, positive bag matching procedures, enhanced passenger and baggage screening and search procedures, and securing of cockpit doors. We strive to comply with or exceed health and safety regulation standards in each applicable jurisdiction. In pursuing these goals, we maintain an active aviation safety program and all of our personnel are expected to participate in the program and take an active role in the identification, reduction and elimination of hazards.

Our ongoing focus on safety relies on training our employees on relevant standards and providing them with the tools and equipment they require so they can perform their job functions in a safe and efficient manner. Safety in the workplace targets several areas of our operation including: flight operations, maintenance, in-flight, dispatch, and station operations.

**PROPOSAL NO. 2: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

Our Board has approved, based on the recommendation of our Audit Committee, the appointment of Ernst & Young LLP ("EY") as our independent registered public accounting firm for the fiscal year ending December 31, 2026. Our Board has directed that this appointment be submitted to our stockholders for ratification. Although ratification of our appointment of EY is not required, we value the opinions of our stockholders and believe that stockholder ratification of the appointment is a good corporate governance practice.

EY has served as our independent registered public accounting firm since 2013. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit related services. A representative of EY is expected to attend our Annual Meeting, will have the opportunity to make a statement if desired, and will be available to respond to appropriate questions from stockholders.

In the event that the appointment of EY is not ratified by the stockholders, the Audit Committee and Board will consider this fact when they appoint the independent registered public accounting firm for the fiscal year ending December 31, 2027. Even if the appointment of EY is ratified, the Audit Committee and our Board retain the discretion to appoint a different independent auditor at any time if they determine that such a change is in the interest of the Company.

**Recommendation of the Board of Directors**

Our Board unanimously recommends that you vote ***"FOR"*** the ratification of the appointment of EY as our independent registered public accounting firm for the fiscal year ending December 31, 2026.

**Principal Accountant Fees and Services**

<sup>(4)</sup> Consists of fees for permitted products and services other than those that meet the criteria above. Such fees are related to an online subscription for audit technology and a research tool for fiscal years 2025 and 2024.

**Pre-Approval Policies and Procedures**

The Audit Committee charter provides that the Audit Committee shall pre-approve all audit and non-audit services provided by the Company's independent registered public accounting firm, unless the engagement is entered into pursuant to appropriate pre-approval policies established by the Audit Committee or if the service falls within available exceptions under the rules and regulations of the SEC.

The Audit Committee approved all audit and non-audit services provided by EY for fiscal years 2025 and 2024, including the estimated costs of those services. Actual amounts billed, to the extent in excess of the estimated amounts, were periodically reviewed and approved by the Audit Committee. The Audit Committee periodically considers whether the non-audit services rendered by EY are compatible with maintaining EY's independence.

**REPORT OF THE AUDIT COMMITTEE**

*The information contained in this Report of the Audit Committee shall not be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (the "Securities Act"), or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing (except to the extent that we specifically incorporate this information by reference) and shall not otherwise be deemed "soliciting material" or "filed" with the SEC, or to the liabilities of Section 18 of the Exchange Act (except to the extent that we specifically incorporate this information by reference).*

The Audit Committee has reviewed the audited consolidated financial statements of the Company for the fiscal year ended December 31, 2025 and has discussed these financial statements with management and the Company's independent registered public accounting firm. The Audit Committee has also received from, and discussed with, the Company's independent registered public accounting firm the matters that they are required to provide to the Audit Committee, including the matters required to be discussed by the Public Company Accounting Oversight Board ("PCAOB") and the SEC.

The Company's independent registered public accounting firm also provided the Audit Committee with a formal written statement required by PCAOB Rule 3526 (Communications with Audit Committees Concerning Independence) describing all relationships between the independent registered public accounting firm and the Company, including the disclosures required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence. In addition, the Audit Committee discussed with the independent registered public accounting firm its independence from the Company.

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit Committee recommended to the Board that the audited consolidated financial statements be included in the Company's 2025 Annual Report.

**PROPOSAL NO. 3: APPROVAL, ON AN ADVISORY (NON-BINDING) BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS**

**Background**

As required by Section 14A(a)(1) of the Exchange Act and related rules of the SEC, the below resolution provides our stockholders an opportunity to vote to approve, on an advisory (non-binding) basis, the compensation of our named executive officers as disclosed in this proxy statement pursuant to the SEC's compensation disclosure rules. This proposal, commonly known as a "Say-on-Pay" proposal and vote, is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies, and practices described in this proxy statement.

We encourage our stockholders to review the "Compensation Discussion and Analysis" and "Executive Compensation Tables" sections of this proxy statement for additional detail regarding the compensation of our named executive officers.

As an advisory approval, this proposal is not binding upon us, our Board, or our Compensation Committee, which is responsible for the design and administration of our executive compensation program. However, the Board and the Compensation Committee value the opinions of our stockholders expressed through your vote on this proposal and continually consider stockholder feedback and the results of Say-on-Pay Votes when making future compensation decisions. Accordingly, we ask our stockholders to vote ***"FOR"*** the following resolution at the Annual Meeting:

"RESOLVED, that the stockholders of Frontier Group Holdings, Inc. approve, on an advisory (non-binding) basis, the 2025 compensation of Frontier Group Holdings, Inc.'s named executive officers as disclosed in the "Compensation Discussion and Analysis" section, the accompanying compensation tables, and the related narrative discussion set forth in Frontier Group Holdings, Inc.'s Proxy Statement for the 2026 Annual Meeting of Stockholders."

Unless the Board or the Compensation Committee modifies the determination on the frequency of future "Say-on-Pay" advisory votes, the next "Say-on-Pay" advisory vote will be held at our 2027 annual meeting of stockholders.

**Recommendation of the Board of Directors**

Our Board unanimously recommends that you vote ***"FOR"*** the resolution to approve, on an advisory (non-binding) basis, the compensation of our named executive officers, as disclosed in the "Compensation Discussion and Analysis" section, the accompanying compensation tables, and the related narrative discussion set forth in this proxy statement.

**DIRECTOR COMPENSATION**

**Compensation Arrangements for our Non-Employee Directors**

All non-employee directors are compensated as follows:

• annual fee of $100,000 payable in cash;

• annual restricted stock units ("RSUs") that have a grant date fair value of $140,000 (increased to $160,000 beginning in 2026), to vest on the earlier of the first anniversary of the date of grant or immediately prior to the next annual meeting of stockholders (subject to continued service);

• additional annual fee to the Chair of the Audit Committee of $25,000 payable in cash;

• additional annual fee to the Chairs for our Compensation Committee, Finance Committee, Nominating and Corporate Governance Committee, and Safety and Security Committee of $20,000 in cash each; and

• travel benefits as discussed below.

Each person who is initially elected to the Board as a non-employee director is granted, on the date of such initial election, a pro-rated grant of RSUs based on the number of days remaining until the first anniversary of the annual meeting of our stockholders that immediately preceded such non-employee director's initial election.

Beginning for 2026 grants, directors have the opportunity to defer the issuance of the shares underlying RSUs until the earliest of a fixed date properly elected by the director, the director's separation from service or a change in control. Any such deferral election is subject to such rules, conditions and procedures approved by the Board.

As is common in the airline industry, we provide flight benefits to the members of the Board under the Universal Air Travel Plan, Inc. ("UATP") card, whereby each individual non-employee director receives a yearly dollar value that they may use for personal travel on Frontier's flights for themselves and certain qualifying friends and family.

For fiscal year 2025, each non-employee director received a travel bank under the UATP equal to $5,500 (except for Mr. W. Franke, who received a travel bank under the UATP equal to $13,750 as the Chair of the Board). Each one-way flight they take is valued based on the average approximate cost to Frontier of a one-way flight. Each non-employee director is also eligible to receive flight benefits following service on the Board, for a period of time equal to the number of years of service for non-employee directors who have served for less than five years, and for life for non-employee directors who have served at least five years, in each case at the same amount of benefits provided during service as a non-employee director. In addition, we reimburse non-employee directors for their reasonable expenses incurred in attending meetings.

**2025 Non-Employee Director Compensation**

The table below provides information regarding compensation we paid to our non-employee directors in 2025. Messrs. James G. Dempsey, our Chief Executive Officer and President, and Barry L. Biffle, our former Chief Executive Officer, are not included in the table because they are employees and receive no compensation for services as a member of the

<sup>(1)</sup> Amounts shown represent the grant date fair value of RSUs granted during fiscal year 2025 as calculated in accordance with ASC Topic 718. See Note 9 to the financial statements included in our 2025 Annual Report for the assumptions used in calculating this amount. On May 15, 2025, each then continuing non-employee director received an annual grant of 34,230 RSUs that, in each case, will vest in full on May 14, 2026, subject to continued service through the vesting date. No other equity awards were made to our non-employee directors during 2025. As of December 31, 2025, each non-employee director held 34,230 RSUs and no other equity awards.

<sup>(2)</sup> Consistent with SEC rules, we have not disclosed perquisites and other personal benefits where the aggregate incremental cost of such compensation was less than $10,000.

<sup>(3)</sup> Mr. MacDonald retired from the Board at the 2025 Annual Meeting on May 15, 2025.

**Director Stock Ownership Guidelines**

Pursuant to our director stock ownership guidelines, each current non-employee director and any newly appointed non-employee director is required to, by the later of April 1, 2026 or, for newly elected directors, the date five years from the date of his or her election to the Board, own shares of our common stock having an aggregate value at least equal to $350,000. For purposes of this calculation, shares of our common stock held directly or indirectly by the non-employee director are included (including shares held by the employer of such director in the case of the directors affiliated with Indigo Partners), including RSUs (vested or unvested) and deferred stock units, if any, while any outstanding and unvested or vested but unexercised stock option awards are excluded.

As of April 1, 2026, each of Messrs. Connor, B. Franke, W. Franke, Broderick, Genise, Han, and Wolff and Mses. Kumpf and Pineda exceeded the director stock ownership guidelines. Ms. Lipson has until July 2029 to meet the director stock ownership guidelines. Mr. Salcido has until February 2031 to meet the director stock ownership guidelines. We will continue to periodically review best practices and re-evaluate our position with respect to stock ownership guidelines.

**EXECUTIVE COMPENSATION**

**Compensation Discussion and Analysis**

The following discussion and analysis of compensation arrangements of our named executive officers ("NEOs") should be read together with the compensation tables and related disclosures set forth below. This discussion contains forward-looking statements that are based on our current plans, considerations, expectations, and determinations regarding future compensation programs.

Our employees, including our NEOs, are employed with Frontier Airlines, Inc. and all compensation matters in respect to our NEOs are determined by our Compensation Committee. All references to "we," "us" or "our" in this Executive Compensation section will refer to Frontier Airlines, Inc. and to our Board and our Compensation Committee for actions taken in respect of equity awards and cash compensation.

Our Compensation Committee, which is appointed by our Board, is responsible for establishing, implementing, and monitoring our compensation philosophy and objectives. We seek to ensure that the total compensation paid to our executive officers is reasonable and competitive. Compensation of our executives is structured around the achievement of near-term corporate targets, long-term business objectives, and individual performance.

**Our NEOs for 2025 were as follows:**

---

| |
|:---|
| Barry L. Biffle, former Chief Executive Officer<sup>(1)</sup> |
| James G. Dempsey, Chief Executive Officer and President<sup>(1)</sup> |
| Howard M. Diamond, Executive Vice President, Legal and Corporate Affairs |
| Mark C. Mitchell, Senior Vice President and Chief Financial Officer |
| Alexandre Clerc, Senior Vice President, Customers |
| Robert A. Schroeter, Senior Vice President, Chief Commercial Officer |

---

<sup>(1)</sup> Effective December 15, 2025, Mr. Biffle was no longer Chief Executive Officer of the Company and Mr. Dempsey was appointed as the interim Chief Executive Officer for the remainder of the year. Mr. Biffle continued to serve as a director and was employed by the Company in an advisory capacity until December 31, 2025. Effective January 7, 2026, Mr. Dempsey was appointed as the Chief Executive Officer.

**Compensation Philosophy and Objectives**

We strive to find the best talent, resources, and infrastructure to better serve our customers. Our goal is to attract and retain the most highly qualified executives to manage and oversee each of our business functions. We seek out individuals who we believe will be able to contribute to our business and our vision of future success, our culture, and values, and who will promote the long-term interests and growth of our company.

In determining the form and amount of compensation payable to the NEOs, we are guided by the following objectives and principles:

• ***Compensation programs should be straightforward, clear, and evolve with our business.*** As part of our development as a business, we aim to ensure our compensation programs are straightforward and clear in order to provide transparency to our stakeholders. Our executive compensation program should give strong, clear incentives to our executives and adapt and evolve to reflect our growth and development to ensure we remain competitive in the marketplace.

• ***Compensation should relate directly to performance, and variable compensation should constitute a significant portion of total compensation.*** We believe that our compensation programs foster an environment of innovation that rewards outstanding performance. Accordingly, a significant portion of total compensation should be based on variable compensation that is tied to and varies with our financial, operational, and strategic performance, as well as individual performance. Executives with greater roles and the ability to directly impact our company's goals and long-term results should bear a greater proportion of the risk if these goals and results are not achieved.

• ***Compensation levels should be designed to attract, motivate, and retain exceptional executives in the markets in which we operate.*** The market for talented management is highly competitive in our industry. We aim to provide an executive compensation program that attracts, motivates, and retains high-performing talent and rewards executives for

**EXECUTIVE COMPENSATION (continued)**

our achieving and maintaining a competitive position in our industry. Total compensation should increase with position and responsibility.

• ***Long-term equity-based compensation should align executives' interests with our stockholders' interests.*** Long-term incentive awards, including equity-based compensation, incentivize executives to manage the Company from a perspective that is beneficial to our stockholders, promoting our long-term growth. Equity-based compensation should be utilized to foster an ownership mentality among our executives and to align the interests of our executives with our stockholders.

**Determination of Compensation**

Our Compensation Committee meets periodically to review and consider recommendations from the Chief Executive Officer with respect to each NEO's base salary, annual bonus compensation, and long-term equity awards, other than with respect to themself. At the same time, our Compensation Committee reviews and determines adjustments, if necessary, to the Chief Executive Officer's compensation, including their base salary, annual bonus compensation, and long-term equity awards. Our Compensation Committee annually evaluates our company-wide performance against the approved performance targets for the prior fiscal year. Our Compensation Committee also meets periodically to discuss compensation-related matters as they arise during the year. For fiscal year 2025, our Compensation Committee determined each individual component of compensation for our NEOs. The Chief Executive Officer evaluates each other NEO's individual performance and contributions at the end of each fiscal year and reports their recommendations regarding each element of the other NEOs' compensation to our Compensation Committee. The Chief Executive Officer does not participate in any discussion with our Compensation Committee regarding decisions on their own compensation and they recuse themselves from meetings when their compensation is discussed.

Our Compensation Committee has also engaged Willis Towers Watson, a compensation consultant, to advise us on compensation philosophy, the selection of a group of peer companies to use for compensation benchmarking purposes, and cash and equity compensation levels for our directors, executives, and other employees based on current market practices. Willis Towers Watson reports directly to our Compensation Committee and does not provide any non-compensation related services to us. Our Compensation Committee has evaluated Willis Towers Watson's independence pursuant to the Nasdaq Rules and the relevant SEC rules and has determined that no conflict of interest has arisen as a result of the work performed by Willis Towers Watson. In addition, our Compensation Committee evaluated the independence of its other outside advisors, including outside legal counsel, considering the same independence factors and concluded their work for the Compensation Committee does not raise any conflicts of interest.

We generally rely on a flexible compensation program that allows us to adapt components and levels of compensation to motivate and reward individual executives to achieve certain Company-wide and individual goals. Subjective factors considered in compensation determinations include an executive's experience and capabilities, contributions to the executive's business unit or department, contributions to our overall company performance, and whether the total compensation structure is sufficient to ensure the retention of the executive after taking into account the compensation potential that may be available elsewhere.

During fiscal year 2025, our Compensation Committee reviewed the primary aspects of our compensation programs for our NEOs, including base salaries, performance-based bonuses, and equity grants. As part of this process, our Compensation Committee consulted compensation surveys and gained a general understanding of current compensation practices through its compensation consultant, Willis Towers Watson.

The surveys provided by Willis Towers Watson reported data on the total compensation, position, and responsibilities of executives employed by similarly situated companies in our industry and other companies based on revenue. Willis Towers Watson led our Compensation Committee through a detailed review of recent executive compensation trends, including as to the form and amount of cash compensation and equity grants. For fiscal year 2025, Willis Towers Watson recommended, and our Compensation Committee approved, the following peer group (the "Compensation Peer Group"), consisting of competitor airlines, for compensation market comparison purposes:

• Alaska Air Group, Inc.

• Hawaiian Holdings, Inc.

• JetBlue Airways Corporation

• Spirit Airlines, Inc.

**<u>[**TABLE OF CONTENTS**](#iad309b32fdcf41888b3af099c69c3438_13)</u>**

**EXECUTIVE COMPENSATION (continued)**

• Allegiant Travel Company

• SkyWest, Inc.

The selection of companies for the Compensation Peer Group focused on small- to medium-sized passenger carriers as an appropriate population for assessing the amounts and percentile rankings of compensation elements for NEOs, including base salaries, short-term incentives (bonuses), and long-term equity-based incentives. Our Compensation Committee determined that our competition for executive talent came significantly from these carriers. Willis Towers Watson primarily used the Compensation Peer Group to assess the competitiveness of our Chief Executive Officer's compensation, as this position would normally be recruited from other passenger airlines.

Consistent with its prior year methodology, in early 2025, in assessing the compensation of our NEOs, Willis Towers Watson used a blended approach consisting of both peer airline proxy and survey data and broader survey data, adjusted for revenue size when possible, as these positions could also be recruited from companies in other industries. Willis Towers Watson weighted the general industry companies at 25% and the airline peer companies at 75% when evaluating our executive compensation and recommending adjustments. For its 2025 analysis, the survey data was pulled from the following three executive pay surveys and projected to spring 2025:

• Seabury's 2019 Airline Industry Compensation Survey;

• Mercer's U.S. SIRS 2019 Airline and Transportation Compensation Survey; and

• Willis Towers Watson's 2024 General Industry Executive Compensation Survey.

When possible, the data from the general industry executive survey was cut in scope to focus on companies with revenues approximating the median revenue of our Compensation Peer Group of approximately $4.5 billion.

Our Compensation Committee has historically approved an overall guideline of total direct compensation for our senior management generally around the market median. Our executive compensation philosophy contemplates that our Compensation Committee would annually select a mix of base salary, annual target incentive compensation, and long-term target incentive compensation intended to deliver total target direct compensation for our executive officers, in the aggregate, at approximately the market 50th percentile. However, our Compensation Committee reserved discretion to deviate from the above guidelines as necessary to account for changing industry characteristics, our particular business model, individual performance, and other factors. Willis Towers Watson's 2025 analysis indicated that, in the aggregate, our NEOs' 2025 total target compensation (base salary plus target bonus opportunity and long-term incentives) was generally aligned with the desired pay positioning, approximating the 50th percentile of the market.

**Components of Compensation for Fiscal Year 2025**

Our performance-driven compensation program for our NEOs consists of the following main components:

• base salary;

• performance-based cash incentives;

• discretionary bonuses;

• equity-based incentives;

• benefits;

• perquisites; and

• termination-based and change-in-control benefits.

We will continue to build our executive compensation program around each of these elements because each individual component is useful in furthering our compensation philosophy and we believe that, collectively, they are effective in achieving our overall objectives.

**Base Salary**

We provide our NEOs with a base salary to compensate them for their service to our company during each fiscal year. The base salary payable to each NEO is intended to provide a fixed component of compensation that adequately reflects the

**EXECUTIVE COMPENSATION (continued)**

executive's qualifications, experience, role, and responsibilities. Base salary amounts are established based on consideration of, among other factors, the scope of the NEO's position, responsibilities and years of service, and our Compensation Committee's general knowledge of the competitive market, based on, among other things, experience with other similarly situated companies and our industry and market data provided by Willis Towers Watson.

Our NEOs' 2025 base salaries are set forth in the table below.

---

| | | |
|:---|:---|:---|
| **Name** | **Annual Base Salary effective as of Year-End** | **Annual Base Salary effective as of Year-End** |
| **Name** | **2025** | **2024** |
| Barry L. Biffle<sup>(1)</sup>  | $747000 | $725000 |
| James G. Dempsey<sup>(1)</sup>  | $657000 | $638000 |
| Howard M. Diamond | $500000 | $485000 |
| Mark C. Mitchell | $488000 | $474000 |
| Alexandre Clerc | $412000 | $400000 |
| Robert A. Schroeter | $427000 | $415000 |

---

<sup>(1)</sup> Effective December 15, 2025, Mr. Biffle was no longer Chief Executive Officer of the Company and Mr. Dempsey was appointed as the interim Chief Executive Officer for the remainder of the year. Mr. Biffle continued to serve as a director and was employed by the Company in an advisory capacity until December 31, 2025. Effective January 7, 2026, Mr. Dempsey was appointed as the Chief Executive Officer. In connection with his appointment as Chief Executive Officer, our Compensation Committee increased Mr. Dempsey's annual base salary to $747,000 effective January 7, 2026.

**Performance-Based Cash Incentives**

As a cornerstone of our compensation policy, we aim to create a direct correlation between the executive's role and responsibilities and the ability to earn variable pay. We provide cash bonuses to reward and incentivize superior individual and business performance, resulting in a performance-based organizational culture. Our performance-based cash incentive plans are designed to reward our executives for innovation and motivate them to achieve both corporate targets and individual goals, thereby tying the executives' goals and interests with our stockholders.

Each of our NEOs was eligible for performance-based cash incentives under our fiscal year 2025 Management Bonus Plan (the "Management Bonus Plan"). The Management Bonus Plan is reviewed and approved annually by our Compensation Committee. The determination of the amount of bonuses paid to our NEOs generally reflects a number of considerations, including our costs and revenues among other corporate targets and, when relevant, individual targets. The formula used to calculate a participating executive's performance-based bonus amount is the sum of the amount calculated for each performance goal, which is found by multiplying the overall target bonus opportunity times the weighting for such performance goal times the achievement level for such performance goal.

Our Compensation Committee expresses each executive's target bonus opportunity as a percentage of base salary earned for the year. Our Compensation Committee did not follow a formula but rather used the factors as general background information prior to determining the target bonus opportunity rates for our NEOs. Our Compensation Committee set these rates based on each NEO's experience in their role with us and the level of responsibility held by each NEO, which our Compensation Committee believes directly correlates to their ability to influence corporate results. For fiscal year 2025, based on market data provided by Willis Towers Watson, our Compensation Committee utilized target bonus opportunities as a percentage of base salary of 125% for Mr. Biffle, 100% for Mr. Dempsey, 75% for Mr. Diamond, and 70% for Messrs. Mitchell, Clerc and Schroeter. Actual bonus payout ranges from 0% to 200% of the target bonus depending on achievement of the performance metrics defined below. In connection with his appointment as Chief Executive Officer, our Compensation Committee increased Mr. Dempsey's fiscal year 2026 target bonus opportunity to 125%.

When determining the bonus amounts for our NEOs under the Management Bonus Plan, our Compensation Committee sets certain performance goals, using a mixture of corporate targets and individual performance. Corporate goals and performance targets and individual performance are reviewed and approved by our Compensation Committee prior to any allocation of the bonus. For fiscal year 2025, our Compensation Committee determined the overall funding of the Management Bonus Plan was based on the achievement of corporate goals, with individual bonuses weighted 75% based on corporate performance and 25% based on individual performance.

In early fiscal year 2025, our Compensation Committee established corporate performance targets for each NEO. Our Compensation Committee does not establish any specific individual performance targets; instead our Compensation

**<u>[**TABLE OF CONTENTS**](#iad309b32fdcf41888b3af099c69c3438_13)</u>**

**EXECUTIVE COMPENSATION (continued)**

Committee reviews at the end of each fiscal year each NEO's individual performance overall and determines bonus payments based on its review of each NEO's overall contributions to us during the fiscal year.

The corporate performance targets established by our Compensation Committee in early 2025 were as follows:

---

| | |
|:---|:---|
| **Performance Metric** | **Weighting** |
| 2025 Year-end Net Cash<sup>(1)</sup> | 35% |
| Full-Year Adjusted CASM (Industry Rank)<sup>(2)</sup> | 35% |
| Operational Objectives<sup>(3)</sup> | 30% |

---

<sup>(1)</sup> Calculated as unrestricted cash and cash equivalents less debt, excluding lease obligations.

<sup>(2)</sup> Adjusted cost per available seat mile ("CASM") is a non-GAAP measure and represents all operating expenses, excluding special items, divided by ASMs. There were no adjustments or special items in 2025 and therefore our adjusted CASM as of December 31, 2025 was equal to CASM, which is a GAAP measure. We believe it is a useful metric to properly compare our cost management and performance to other peers, as derivations of adjusted CASM are well-recognized performance measurements in the airline industry that are frequently used by our management, as well as by investors, securities analysts and other interested parties in comparing the operating performance of companies in the airline industry. Additionally, the Company believes this metric is useful because it removes certain items that may not be indicative of base operating performance or future results. Adjusted CASM is not determined in accordance with GAAP, may not be comparable across all carriers and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.

<sup>(3)</sup> Refers to the following four operation objectives: (1) Aircraft Availability at Start of Day, (2) Controllable Turn Performance, (3) Head Start On-Time Percentage and (4) DOT Mishandled Bag Rate (Industry Rank)

For each of these performance goals under the Management Bonus Plan, our Compensation Committee sets a threshold, target, stretch, and maximum achievement level. A component of performance must be achieved at no less than 50% before it is taken into account in calculating an executive's bonus amount and achievement cannot exceed 200% of the target for any component. The threshold goals correspond to an achievement level of 50%, the target goals correspond to an achievement level of 100%, the stretch goals correspond to an achievement level of 150%, and the maximum goals are satisfied with an achievement level of 200%. The threshold, target, stretch, and maximum achievement levels for fiscal year 2025 are included in the table below. In early 2026, our Compensation Committee reviewed our fiscal year 2025 company-wide performance with respect to determining bonuses to executive officers, as well as individual performance achievements. Based on the percent achieved for each individual corporate performance goal, as set forth in the table below, our Compensation Committee determined the total corporate performance percent achieved to be 130%. Our Compensation Committee also determined the achievement of the individual performance goals at 100% for Messrs. Biffle, Clerc, and Schroeter, 120% for Messrs. Diamond and Clerc, and 110% for Messrs. Dempsey and Mitchell.,

For fiscal year 2026, our Compensation Committee has approved the fiscal year 2026 Management Bonus Plan for all executives. The 2026 Management Bonus Plan for our executives is similar to the 2025 Management Bonus Plan.

**Equity-based Incentives**

Our Compensation Committee fosters an environment of executive ownership that encourages and incentivizes long-term investment and engagement by our NEOs through the use of equity-based awards. Our aim is to promote long-term, sustainable growth, and align executive performance and behaviors to create a culture conducive to stockholder investment.

In order to attract and retain the best available management and other personnel with the training, experience, and ability to make substantial contributions to the success of our business and to motivate and provide additional incentives to our employees, non-employee directors, and consultants, we adopted the 2021 Plan, which became effective immediately prior to the consummation of our initial public offering. The 2021 Plan replaced our 2014 Equity Incentive Plan (the "2014 Plan") and no further grants will be made under the 2014 Plan. The 2014 Plan terminated in connection with the adoption of the 2021 Plan, except with regard to grants then outstanding under the 2014 Plan.

When determining the size of the grants for NEOs, our Board takes into account the size of past equity grants, the NEO's position (level) in our company, compensation, the NEO's value for our company based on their experience, innovation, expertise, and leadership capabilities and the recommendation of our Compensation Committee. The philosophy behind the equity grants is to provide the NEO with a strong incentive to build long-term value in our company.

For fiscal year 2025, we introduced performance-based restricted stock unit ("PSUs") grants to our NEOs in addition to the annual time-based restricted stock units ("RSUs"). The RSUs vest as to one-third of the total number of RSUs on each anniversary of the grant date, ending in 2028, subject to continued service, with certain contractual exclusions, through each vesting date.

Each PSU award is granted at a target number, which represents the right to receive one share of common stock that may be issued to the participant provided certain performance and service conditions are met during each performance period.

**<u>[**TABLE OF CONTENTS**](#iad309b32fdcf41888b3af099c69c3438_13)</u>**

**EXECUTIVE COMPENSATION (continued)**

The annual PSU award granted is subject to a three-year performance period beginning January 1, 2025 and ending December 31, 2027 and vests on the third anniversary of the grant date, subject to continued service. For fiscal year 2025 only, our Compensation Committee approved one-time bridge PSU grants in order to maintain the NEOs' annual vesting opportunities for 2026 and 2027. These one-time PSU grants are subject to one- and two-year performance periods beginning January 1, 2025 and ending December 31, 2025 and December 31, 2026, respectively, and vest on the first and second anniversaries of the grant date, respectively, in order to maintain the NEOs' annual vesting opportunities for 2026 and 2027. The service condition for all PSUs granted requires continued service, with certain contractual exclusions, through the end of each vesting period. In addition to the service condition, each PSU was granted with either a non-market or market condition. The non-market and market conditions require achievement of certain adjusted pre-tax margin and total shareholder return targets, respectively, over each performance period. The number of shares of common stock awarded will be determined based on the achievement factor for the performance period ranging from 0% to 200% of the target shares. The achievement factor will be determined by summing the product of each condition's weight multiplied by the relative achievement factor.

The table below set forth the grants of RSUs and PSUs made to our NEOs on February 6, 2025.

|:---|:---|:---|:---|:---|:---|:---|:---|
| **Performance and Market Conditions** | **Weight**<sup>(4)</sup> | **Relative Achievement Factor** | **Relative Achievement Factor** | **Relative Achievement Factor** | **Relative Achievement Factor** | **Relative Achievement Factor** | **Relative Achievement Factor** |
| **Performance and Market Conditions** | **Weight**<sup>(4)</sup> | **0** | **0.5** | **0.75** | **1.0** | **1.5** | **2.0** |

<sup>(1)</sup> Adjusted pre-tax margin is a non-GAAP measure and represents pre-tax income (loss), adjusted for special items, divided by revenues. The sum of these non-GAAP adjustments is referred to as the "pre-tax impact." We believe it is a useful indicator to compare the profitability of our business against industry peers of different sizes and derivations of pre-tax income (loss) are well-recognized performance measurements in the airline industry that are frequently used by our management, as well as by investors. Adjusted pre-tax margin is not determined in accordance with GAAP, may not be comparable across all carriers, and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP. See Appendix A for the reconciliation of adjusted pre-tax margin to the comparable GAAP measure.

<sup>(2)</sup> Total shareholder return represents the change in the price of a share over the performance period (positive or negative). It is calculated based on the average market value (based on the average closing price during the twenty consecutive trading days) ending on the first day of the performance period as the beginning stock price, and the average market value (based on the average closing price during the twenty consecutive trading days)

ending on the last day of the performance period as the ending stock price, and assuming dividends (if any) are reinvested based on the price of a share in accordance with the "total" return methodology. If the Company's total stockholder return for the performance period is negative, the achievement factor will be capped at 1.0.

<sup>(3)</sup> The industry includes the following carriers: American Airlines, Delta Air Lines, United Airlines, Southwest Airlines, Alaska Airlines, JetBlue Airways Corporation, Allegiant Air and Frontier Airlines.

<sup>(4)</sup> 50% of the target grant value was granted as non-market PSUs tied to our adjusted pre-tax margin ranking based on the closing price on the grant date and 50% of the target grant value was granted as market PSUs tied to our total shareholder return ranking based on a Monte Carlo simulation model as of the grant date. Given the different valuation methodologies, approximately 59% of the number of PSUs are tied to our adjusted pre-tax margin ranking and 41% of the PSUs are tied to our total shareholder return ranking.

For fiscal year 2026, in connection with his appointment as Chief Executive Officer, Mr. Dempsey's fiscal 2026 long-term equity incentive awards will have an aggregate grant date fair value equal to $3,500,000 and will be granted in the ordinary course. The award vehicles, mix and vesting terms and conditions will be consistent with the terms and conditions of the equity awards to be granted to our other executive officers. In addition, the Compensation Committee approved a

**EXECUTIVE COMPENSATION (continued)**

promotion PSU grant to Mr. Dempsey, with a target grant date fair value of $1,750,000, which will cliff vest on the fourth anniversary of the grant date, subject to his continuing service to the Company through the vesting date. The number of shares that will be earned, if any, is determined by a performance multiplier by dividing the average closing price of the Company's shares of common stock as of the end of the four-year performance period (with a maximum capped at $30 per share) by the average closing price of the Company's shares of common stock as of the beginning of the performance period. In addition, there would be no payout at the end of the performance period if the average share price is below 50% of the average share price as of the beginning of the performance period.

For the one-time bridge PSU grant with a one-year performance period with a scheduled vest date of February 6, 2026, we assessed performance as of December 2025. The Company ranked 7 out of 8 and 6 out of 8 for the one-year adjusted pre-tax margin and one-year total shareholder return PSUs, respectively. As a result, a 0% and 50% achievement factor was applied to the adjusted pre-tax margin and total shareholder return bridge grants with a one-year performance period, respectively, which resulted in a corresponding 100% and 50% forfeiture of the adjusted pre-tax margin and total shareholder return one-year performance bridge PSU grants, respectively. In addition, in January 2026, 50% of Mr. Biffle's two-year PSU awards were forfeited, 66% of his three-year PSU awards were forfeited, and all of his remaining RSUs which were scheduled to service-vest after February 2026 were forfeited.

Equity forms an integral part of the overall compensation for each executive officer and will be considered each year as part of the annual performance review process and incentive payout calculation. In the future, we may consider awarding additional forms of equity incentives, such as grants of restricted stock and performance-based awards, and may also determine to seek additional input from compensation consultants. We expect that the equity awards we make to our executive officers will be driven by our sustained performance and growth, our executive officers' ability to impact our results that influence stockholder value, their organization level and their potential to take on roles of increasing responsibility.

**Benefits**

We provide the following benefits to all our employees, including our NEOs:

• medical, dental and vision insurance;

• life, accidental death and dismemberment, and business travel and accident insurance;

• employee assistance program;

• health and dependent care flexible spending accounts;

• short and long-term disability; and

• 401(k) plan, which includes an employer matching contribution of 50% of the applicable employee's first 6% of plan contributions.

Our Compensation Committee, in its discretion, may revise, amend or add to any executive officer's benefits if it deems necessary. Consistent with our overall compensation philosophy, we intend to continue to maintain our current benefits plans for executives as well as other employees.

**Perquisites and Other Compensation**

We determine perquisites on a case-by-case basis and will provide a perquisite to a NEO when we believe it is necessary to attract or retain the executive officer. Any perquisites we supply are reasonable and consistent with market trends. We believe that providing these benefits is a relatively inexpensive way to enhance the competitiveness of the executive's compensation package. As is common in the airline industry, we provide a UATP to our executive officers, whereby each individual receives a yearly dollar value that they may use for personal travel on our flights for themselves and certain qualifying friends and family. Each one-way flight they take is valued based on the average approximate cost of a one-way flight for us. For fiscal year 2025, Mr. Biffle received a travel bank under the UATP equal to $20,000, and Messrs. Dempsey, Diamond, Mitchell, Clerc, and Schroeter each received a travel bank under the UATP equal to $8,250. Each officer is also eligible to receive flight benefits following the end of their employment relationship with us, for a period of time equal to the number of years of employment for executive officers who have been employed by us for at least five

**EXECUTIVE COMPENSATION (continued)**

years and less than ten years, and for life for executive officers who have been employed by us for at least ten years, in each case at the same amount provided during employment as an executive officer.

**Termination-Based Compensation**

We believe that terminations of employment are causes of great concern and uncertainty for our senior executives. We aim to alleviate these concerns and allow executives to remain focused on their duties and responsibilities to us by providing protections to our executives in the termination context. As such, each of our NEOs is eligible for severance benefits under his employment agreement.

Each of our NEOs is eligible for severance benefits, both in connection with and outside of a change in control, under his respective employment agreement with us. Our Compensation Committee and/or our Board approves of termination benefits to our NEOs based on its general knowledge of severance practices in our industry and as the result of arms' length negotiations at the time our executives enter into employment with us or at the time they are requested to take on additional responsibilities. The level of benefits varies from executive to executive based on the level of responsibility of the executive and accommodations made through arms' length negotiations. Severance payments are typically comprised of a cash payment in lieu of salary or bonus, continuation of flight benefits under the UATP for a limited period of time, and coverage of health benefits for a limited period of time. Executive officers whose employment is terminated by us are required to sign a general release of all claims to receive any severance benefits.

On December 15, 2025, our Board announced the departure of Mr. Biffle as the Company's Chief Executive Officer. Mr. Biffle continued to serve as a director and was employed in an advisory capacity until December 31, 2025. Mr. Biffle's separation qualified as a termination without "cause" entitling him to certain severance benefits in 2026 consistent with the terms of his employment agreement. For more detailed descriptions of Mr. Biffle's separation agreement, please see "Executive Compensation Tables—Employment and Separation Agreements with NEOs" and "Executive Compensation Tables—Potential Payment upon Termination or Change in Control" below.

**Clawback Policy**

We have adopted a Policy for Recovery of Erroneously Awarded Compensation that applies to our executive officers in compliance with SEC rules and Nasdaq listing standards. The policy is administrated by our Compensation Committee and applies in the event we are required to prepare an accounting restatement of our financial statements due to our material noncompliance with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. Under the policy, the Company is required to recover the amount of certain erroneously awarded incentive compensation received by any executive officer on or after October 2, 2023 (the effective date of the policy) in the event of an accounting restatement.

**Tax and Accounting Considerations**

While our Board and our Compensation Committee generally consider the financial accounting and tax implications of their executive compensation decisions, neither element has been a material consideration in the compensation awarded to our NEOs historically.

Section 409A of the Internal Revenue Code, which governs the form and timing of payment of deferred compensation, imposes sanctions, including a 20% penalty and an interest penalty, on the recipient of deferred compensation that does not comply with Section 409A. Our Compensation Committee will take into account the implications of Section 409A in determining the form and timing of compensation awarded to our executives and will strive to structure any non-qualified deferred compensation plans or arrangements to be exempt from or to comply with the requirements of Section 409A.

Section 280G of the Internal Revenue Code disallows a company's tax deduction for payments received by certain individuals in connection with a change in control to the extent that the payments exceed an amount approximately three times their average annual compensation and Section 4999 of the Internal Revenue Code imposes a 20% excise tax on those payments. Our Compensation Committee will take into account the implications of Section 280G in determining potential payments to be made to our executives in connection with a change in control. Nevertheless, to the extent that certain payments upon a change in control are classified as excess parachute payments, such payments may not be deductible pursuant to Section 280G.

<sup>(1)</sup> Reflects a weighted amount based on the portion of the year for which different base salaries applied.

<sup>(2)</sup> Amounts shown represent the grant date fair value of RSUs and PSUs granted by us, as calculated in accordance with ASC Topic 718. See Note 9 of the financial statements included in our 2025 Annual Report for the assumptions used in calculating these amounts. The grant date fair value of adjusted pre-tax margin PSUs was measured based on the probable outcome of the performance vesting conditions as of the grant date, which was at the target performance level. The grant date value of the adjusted pre-tax margin PSUs assuming that the highest level of performance conditions will be achieved would have been, $2,999,999, $1,799,993 and $889,997 for Messrs. Biffle, Dempsey, and Diamond, respectively, and $700,012, for Messrs. Mitchell, Clerc and Schroeter. The grant date fair value of total shareholder return PSUs was measured based on the application of a Monte Carlo simulation model to determine the probable outcomes of the market-based performance conditions. The vesting conditions related to the total shareholder return PSUs are considered market conditions and not performance conditions pursuant to ASC Topic 718. Based on the Monte Carlo simulation model, grant date fair values of the market condition component of PSUs were 142%-147% of our average stock price on the grant date.

Please see the description of the 2025 Management Bonus Plan in "Compensation Discussion and Analysis —Performance-Based Cash Incentives" above.

Consistent with SEC rules, we have not disclosed perquisites and other personal benefits where the aggregate amount of such compensation was less than $10,000. Please see the descriptions of the perquisites in "Compensation Discussion and Analysis—Perquisites" above.

<sup>(1)</sup> Amounts in the "Estimated Future Payouts Under Non-Equity Incentive Plan Awards" column relate to amounts payable under our 2025 Management Bonus Plan. The threshold column assumes the achievement of the corporate and individual goals at the threshold level. The threshold bonus amount can be calculated by multiplying the target bonus of each NEO times the threshold achievement percentage of 50%. The target column assumes the target achievement for both corporate and individual goals. The target bonus amount can be calculated by multiplying the weighted base salary of each NEO for 2025 times the target bonus percentage established by our Compensation Committee and times the target achievement percentage of 100%. The maximum column assumes the maximum achievement for both corporate and individual goals. The maximum bonus amount can be calculated by multiplying the target bonus of each NEO times the maximum achievement percentage of 200%.

**EXECUTIVE COMPENSATION TABLES (continued)**

See "Summary Compensation Table" presented above for target bonus amounts and actual amounts paid to our NEOs in early 2026 for performance in fiscal year 2025 under our Management Bonus Plan.

<sup>(2)</sup> Under the performance share unit award agreement, no payment is made until a minimum performance level is met, and performance at or above such level will result in a payment ranging from zero shares to the maximum amount, subject to the approval of the Compensation Committee.

<sup>(3)</sup> Amounts in the "All Other Stock Awards: Number of Shares if Stock or Units" column represent the number of RSUs that were granted to each NEO. The RSUs vest as to one-third of the total number of RSUs on each of February 6, 2026, February 6, 2027 and February 6, 2028, subject to the executive continuing to provide services to us through such date, with certain contractual exclusions.

<sup>(4)</sup> Amounts shown in the "Grant Date Fair Value of Stock and Option Awards" column represent the grant date fair value of RSUs and PSUs granted, as calculated in accordance with ASC Topic 718. See Note 9 of the financial statements included in our 2025 Annual Report for the assumptions used in calculating these amounts. The grant date fair value of adjusted pre-tax margin PSUs was measured based on the probable outcome of the performance vesting conditions as of the grant date, which was at the target performance level. The grant date fair value of relative TSR PSUs was measured based on the application of a Monte Carlo simulation model to determine the probable outcomes of the market-based performance conditions.

<sup>(5)</sup> Effective December 15, 2025, Mr. Biffle was no longer Chief Executive Officer of the Company and Mr. Dempsey was appointed as the interim Chief Executive Officer for the remainder of the year. Mr. Biffle continued to serve as a director and was employed by the Company in an advisory capacity until December 31, 2025. Effective January 7, 2026, Mr. Dempsey was appointed as the Chief Executive Officer. As such, in 2026, 50% of Mr. Biffle's two-year PSU awards were forfeited, 66% of his three-year PSU awards were forfeited, and all remaining RSUs which were scheduled to service-vest after February 2026 were forfeited.

<sup>(6)</sup> Amounts represent the target number of the one-time bridge PSU awards granted that are subject to a one-year performance period beginning January 1, 2025 and ending December 31, 2025 and vest on the first anniversary of the grant date, subject to continued service. Each unit represents the right to receive one share of common stock that may be issued to the participant provided performance and service conditions are met. The number of shares of common stock awarded will be determined based on the achievement factor of the performance metric, ranging from 0% to 200% of the target shares. See "Compensation Discussion and Analysis—Equity-based Incentives" above for further detail on targets and achievement factors achieved.

<sup>(7)</sup> Amounts represent the target number of the one-time bridge PSU awards granted that are subject to a two-year performance period beginning January 1, 2025 and ending December 31, 2026 and vest on the second anniversary of the grant date, subject to continued service. Each unit represents the right to receive one share of common stock that may be issued to the participant provided performance and service conditions are met. The number of shares of common stock awarded will be determined based on the achievement factor of the performance metric, ranging from 0% to 200% of the target shares. See "Compensation Discussion and Analysis—Equity-based Incentives" above for further detail on targets and achievement factors.

<sup>(8)</sup> Amounts represent the target number of the annual PSU awards granted that are subject to a three-year performance period beginning January 1, 2025 and ending December 31, 2027 and vest on the third anniversary of the grant date, subject to continued service. Each unit represents the right to receive one share of common stock that may be issued to the participant provided performance and service conditions are met. The number of shares of common stock awarded will be determined based on the achievement factor of the performance metric, ranging from 0% to 200% of the target shares. See "Compensation Discussion and Analysis—Equity-based Incentives" above for further detail on targets and achievement factors.

and for 12 months thereafter (or 24 months in the event of a termination of Mr. Biffle's employment without Cause or his Constructive Termination). The employment agreement also provided for the grant of an option to purchase shares of our common stock, as detailed in the table "Outstanding Equity Awards at Fiscal Year End" above and provides him with severance in the event of a termination of Mr. Biffle's employment without Cause or his Constructive Termination, both within and apart from a Change in Control (as defined below).

Mr. Biffle must execute, and not revoke, a general release of all claims against us and our affiliates to receive of the severance payments described above, and any payments are subject to him continuing to abide by the confidentiality, non-competition, and non-solicitation provisions of his employment agreement.

For purposes of Mr. Biffle's employment agreement, "Cause" means (i) Mr. Biffle's gross negligence or willful misconduct in the performance of the duties and services required of him pursuant to the new employment agreement or any other written agreement between Mr. Biffle and us; (ii) his conviction of, or plea of guilty or nolo contendere to, a felony or crime involving moral turpitude (or any similar crime in any jurisdiction outside the United States); (iii) his willful refusal to perform the duties and responsibilities required of him under the new employment agreement or as lawfully directed by our Board which remains uncorrected for 30 days following written notice; (iv) his material breach of any material provision of the employment agreement, any confidential information or restrictive covenant agreement with us, or corporate code or policy which remains uncorrected for 30 days following written notice; (v) any act of fraud, embezzlement, material misappropriation, or dishonesty committed by him against us; or (vi) any acts, omissions or statements by him which we determine to be materially detrimental or damaging to our reputation, operations, prospects or business relations; provided that an act or failure to act shall be considered "willful" only if done or omitted to be done without a good faith reasonable belief that such act or failure to act was in our best interests.

"Change in Control" means (i) the acquisition by any person or group of affiliated or associated persons of more than 50% of the outstanding capital stock of us or Frontier or voting securities representing more than 50% of the total voting power of outstanding securities of us or Frontier (other than such an acquisition by a person or group that holds more than 50% of the outstanding capital stock of us or Frontier or voting securities representing more than 50% of the total voting power of outstanding securities of us or Frontier, in each case, as of either March 15, 2016 or immediately prior to such acquisition); (ii) the consummation of a sale of all or substantially all of our assets to a third-party; (iii) the consummation of any merger involving us or Frontier in which, immediately after giving effect to such merger, less than a majority of the total voting power of outstanding stock of the surviving or resulting entity is then beneficially owned in the aggregate by the stockholders of us or Frontier, as applicable, immediately prior to such merger; provided, however, in no event will a transaction constitute a "Change in Control" if: (w) its sole purpose is to change the form of our ownership or the state of our incorporation; (x) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held our securities immediately before such transaction; (y) it is effected primarily for the purpose of financing us with cash; or (z) it constitutes, or includes sales of shares in connection with, the initial public offering of our common stock or the common stock of any of our affiliates.

**EXECUTIVE COMPENSATION TABLES (continued)**

Notwithstanding the foregoing, a resignation shall not constitute a Constructive Termination unless the condition giving rise to such resignation continues uncured by us more than 30 days following Mr. Biffle's written notice of such condition provided within 60 days of the first occurrence of such condition and such resignation is effective within 30 days following the end of such notice period.

On December 15, 2025, the Board announced the departure of Mr. Biffle as our Chief Executive Officer. Mr. Biffle continued to serve as a director and was employed in an advisory capacity until December 31, 2025. Mr. Biffle's separation qualified as a termination without "cause" entitling him to certain severance benefits in 2026 consistent with the terms of his employment agreement, which are described above. Under his separation agreement, dated January 1, 2026, Mr. Biffle became entitled to receive, subject to a release requirement and continued compliance with his restrictive covenants, including non-competition and non-solicitation restrictive covenants for twelve months following his separation date, severance equal to one times his annual base salary plus target bonus and an amount intended to cover coverage pursuant to COBRA for a twelve-month period. In addition, consistent with the terms of the PSU agreements, the PSUs granted to Mr. Biffle will remain outstanding and a pro-rated number of such PSUs, based on the portion of the performance period Mr. Biffle had remained in service, will vest upon the completion of the performance period based on the actual achievement of the goals. We also agreed to permit the tranche of Mr. Biffle's RSUs that were scheduled to vest in February 2026 to continue to vest given that he had remained in service during a substantial part of the vesting period.

**James G. Dempsey.** In March 2014, we entered into an employment agreement with Mr. Dempsey as our Chief Financial Officer, which is terminable by us at any time and by Mr. Dempsey upon 30 days' notice, which was amended and restated in April 2017 and amended further in October 2023 and January 7, 2026 in connection with Mr. Dempsey's promotion to President and Chief Executive Officer, respectively. The initial term of his employment agreement was through March 12, 2018, and the term renews for successive one-year periods unless either party gives the other notice of non-extension at least 120 days before the expiration of the applicable term. Mr. Dempsey's employment agreement entitles him to a base salary and a target bonus opportunity as part of our Management Bonus Plan and provides that he will be eligible to participate in all employee benefit plans made available to executive officers (including the flight benefits under the UATP discussed above) and also contains certain confidential information covenants. In addition, Mr. Dempsey must abide by non-competition and non-solicitation restrictive covenants during the term of his employment and for 12 months thereafter. Mr. Dempsey's employment agreement provides him with severance in the event of a termination of his employment without Cause (as defined below) or his Constructive Termination (as defined below), both within and apart from a Change in Control (as defined below). In the event of the termination of his employment by us without Cause, Mr. Dempsey is entitled to (a) a lump sum payment equal to one times the sum of his base salary plus his target annual performance bonus, (b) the payment of continued health, dental, and vision insurance premiums for him and any covered dependents for 12 months, and (c) a pro-rated annual performance bonus with respect to the year in which the termination occurs based on actual performance and payable at the same time as other continuing executive officers, and (d) continued flight benefits under the UATP for one year. In the event of a termination of Mr. Dempsey's employment by us without Cause or his Constructive Termination, in each case, within 12 months following a Change in Control, Mr. Dempsey is entitled to (a) lump sum payment equal to two times the sum of his base salary plus his target annual performance bonus, (b) the payment of continued health, dental, and vision insurance premiums for him and any covered dependents for 24 months, (c) continued flight benefits under the UATP for two years, (d) 100% accelerated vesting of all of his outstanding equity awards, and (e) a pro-rated annual performance bonus with respect to the year in which the termination occurs based on actual performance and payable at the same time as other continuing executive officers. Under the employment agreement, Mr. Dempsey must execute, and not revoke, a general release of all claims against us and our affiliates to receive of the severance payments described above, and any payments are subject to Mr. Dempsey continuing to abide by the confidentiality, non-competition and non-solicitation provisions of his employment agreement.

For purposes of Mr. Dempsey's employment agreement, "Cause" and "Constructive Termination" have the same meanings as were included in Mr. Biffle's employment agreement. In the event we give Mr. Dempsey a notice of non-extension of his employment agreement and he serves as our President and Chief Executive Officer until the end of the term, Mr. Dempsey's employment will have been deemed terminated by us without Cause.

"Change in Control" means (i) the acquisition by any person or group of affiliated or associated persons of more than 40% of the outstanding capital stock of us or Frontier or voting securities representing more than 40% of the total voting power of outstanding securities of us or Frontier (other than such an acquisition by a person or group that holds more than forty percent (40%) of the outstanding capital stock of us or Frontier or voting securities representing more than forty percent (40%) of the total voting power of outstanding securities of us or Frontier, in each case, as of either the effective date of the

agreement or immediately prior to such acquisition); (ii) the consummation of a sale of all or substantially all of the assets of the Company to a third-party; or (iii) the consummation of any merger involving us or Frontier in which, immediately

Exchange Act of 1934, as amended) in the aggregate by the stockholders of us or Frontier, as applicable, immediately prior to such merger. A transaction will not constitute a "Change in Control" if: (w) its sole purpose is to change the form of ownership of Frontier or its state of incorporation; (x) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held Frontier's securities immediately before such transaction; or (y) it is effected primarily for the purpose of financing Frontier with cash.

**Howard M. Diamond and Mark C. Mitchell.**

In October 2023 and February 2024, respectively, we entered into new offer letter agreements with Messrs. Diamond and Mitchell in connection with their promotions to Senior Vice President and Chief Financial Officer and Executive Vice President, Legal and Corporate Affairs, respectively. Under their offer letter agreements, each executive's employment is terminable by us or by the executive at any time. Each offer letter agreement entitles the executive to a base salary and a target bonus opportunity as part of our Management Bonus Plan and provides that the executive will be eligible to participate in all employee benefit plans made available to executive officers (including the flight benefits under the UATP discussed above) and also contains certain confidential information covenants. In addition, under their offer letter agreements, each executive must abide by non-competition and non-solicitation restrictive covenants during the term of his employment and for 12 months thereafter (or 24 months in the event the executive is terminated without Cause or his duties are substantially diminished and he resigns within 12 months following a Change in Control).

The offer letter agreements provide that, in the event of the termination of the executive's employment by us without Cause, he is entitled to (a) a lump sum payment of one times the sum of his base salary and target bonus and (b) continued flight benefits under the UATP for one year. In the event of the termination of his employment by us without Cause or his resignation for Good Reason, in each case, within 12 months following a Change in Control, the executive is entitled to (a) a lump sum payment of two times the sum of his base salary and target bonus, (b) continued flight benefits under the UATP for two years and (c) each outstanding equity award he holds will fully accelerate as to 100% of the shares. The severance payments and benefits described above are subject to continued compliance with the restrictive covenants, as set forth in the offer letter agreement, and each executive must execute, and not revoke, a general release of all claims against us and our affiliates.

For the purposes of the new offer letter agreements with Messrs. Diamond and Mitchell, "Cause" and "Change in Control" have the meanings set forth under the Company's 2021 Incentive Award Plan, or in the case of a Change in Control, if specified in the applicable award agreement, such agreement.

"Good Reason" means (a) a material diminution in base salary that is not proportionately applicable to other similarly situated employees; (b) a material diminution in job responsibilities or duties inconsistent in any material respect with duties or responsibilities in effect immediately prior to such change, provided, that any change made solely as the result of us or Frontier becoming a subsidiary or business unit of a larger company in a change in control shall not provide for Good Reason; or (c) the failure by any successor entity or corporation following a change in control to assume the obligations under the offer letter agreement. The executive will not be deemed to have Good Reason unless the condition giving rise to such resignation continues uncured by us more than 30 days following his written notice of such condition provided to us within 60 days of the first occurrence of such condition and such resignation is effective within 30 days following the end of such notice period.

**Alexandre Clerc.** We entered into an offer letter agreement with Mr. Clerc effective as of January 8, 2024 as our Senior Vice President, Customers. Under the agreement, Mr. Clerc's employment is terminable by us or Mr. Clerc at any time. Mr. Clerc's offer letter agreement also entitles Mr. Clerc to a base salary and a target bonus opportunity as part of our Management Bonus Plan and provides that Mr. Clerc will be eligible to participate in all employee benefit plans made available to executive officers (including the flight benefits under the UATP discussed above) and also contains certain confidential information covenants. In addition, under the offer letter agreement, Mr. Clerc must abide by non-competition and non-solicitation restrictive covenants during the term of his employment and for 12 months thereafter (or 24 months in the event he is terminated without Cause or his duties are substantially diminished and he resigns within 12 months following a Change in Control.

**EXECUTIVE COMPENSATION TABLES (continued)**

Mr. Clerc's offer letter agreement provides that the vesting of his initial grant of RSUs will fully accelerate upon the consummation of a Change in Control and that in the event of the termination of his employment by us without Cause, Mr. Clerc is entitled to (a) a lump sum payment of one times the sum of his base salary and target bonus (or two times such sum if such termination occurs or his duties are substantially diminished and he resigns, in each case, within 12 months following a Change in Control) and (b) continued flight benefits under the UATP for one year (or two years if such termination occurs or his duties are substantially diminished and he resigns, in each case, within 12 months following a Change in Control). Mr. Clerc must execute, and not revoke, a general release of all claims against us and our affiliates to receive the severance payments described above.

For the purposes of the employment agreement with Mr. Clerc, "Cause" and "Change in Control" have the meanings set forth under the Company's equity plan.

**Robert A. Schroeter.** We entered into an offer letter agreement with Mr. Schroeter effective as of March 25, 2024 as our Senior Vice President, Chief Commercial Officer. Under the agreement, Mr. Schroeter's employment is terminable by us or Mr. Schroeter at any time. Mr. Schroeter's offer letter agreement also entitles Mr. Schroeter to a base salary and a target bonus opportunity as part of our Management Bonus Plan and provides that Mr. Schroeter will be eligible to participate in all employee benefit plans made available to executive officers (including the flight benefits under the UATP discussed above) and also contains certain confidential information covenants.

Mr. Schroeter must execute, and not revoke, a general release of all claims against us and our affiliates to receive the severance payments described above.

For the purposes of the employment agreement with Mr. Schroeter, "Cause" and "Change in Control" have the meanings set forth under the Company's equity plan.

**Change in Control Acceleration under Equity Plan and Equity Award Agreements**

Under the 2021 Plan, in the event of a Change in Control (as defined therein), unless the administrator elects to (i) terminate an award in exchange for cash, rights, or property, or (ii) cause an award to become fully exercisable and no longer subject to any forfeiture restrictions prior to the consummation of a Change in Control, (A) such award (other than any portion subject to performance-based vesting) shall continue in effect or be assumed or an equivalent award substituted by the successor corporation and (B) the portion of such award subject to performance-based vesting shall be subject to the terms and conditions of the applicable award agreement and, in the absence of applicable terms and conditions, the administrator's discretion. In the event that the successor refuses to assume or substitute for an award (other than any portion subject to performance-based vesting), such award shall become fully vested and, if applicable, exercisable immediately prior to the consummation of such transaction.

Under the PSU agreements, if a Change in Control (as defined therein) occurs, then a number of PSUs equal to the greater of (i) such number of PSUs as would vest based on the actual achievement factor (as determined by the administrator as of the Change in Control), and (ii) such number of PSUs as would vest based on the achievement factor of 1.0 (such greater number, the "Deemed Performance Vested Units") will be deemed to performance vest upon the Change in Control. If the PSUs are not assumed or substituted by the surviving corporation in connection with the Change in Control, then the Deemed Performance Vested Units will fully vest upon the Change in Control. If the Deemed Performance Vested Units are assumed or substituted by the surviving corporation, they will continue to vest based on the original service vesting schedule based on the participant's continued service and the vesting of the Deemed Performance Vested Units will only accelerate if the participant experiences a termination without Cause or for Good Reason within twelve months following the Change in Control. Such vesting acceleration is subject to the participant delivering a general release of all claims and participant's compliance with restrictive covenants.

**EXECUTIVE COMPENSATION TABLES (continued)**

In the event of a termination without Cause or for Good Reason or due to death or Disability (in each case, as defined in the PSU agreements), the PSUs will remain outstanding and a pro-rated portion of the PSUs based on the portion of the performance period that the participant remained in service will vest upon the completion of the performance period based on the actual achievement factor as determined by the administrator. Such vesting acceleration is subject to the participant delivering a general release of all claims and participant's compliance with restrictive covenants.

**Change in Control Policy**

On February 3, 2022, the Compensation Committee approved a policy providing for the following: if the employment of any executive officer is terminated without "cause" or the executive officer resigns for "good reason" in connection with a qualifying change in control, then in exchange for a release of claims, the executive officer's outstanding equity awards will fully vest (the "Change in Control Policy"). For purposes of the Change in Control Policy, a "qualifying change in control" includes transactions whereby any person (or group of persons) directly or indirectly acquires beneficial ownership of our securities representing 40% or more of the total combined voting power of our securities outstanding immediately after such transaction. The Change in Control Policy also provides that under each executive officer's existing employment agreement or offer letter, for purposes of severance benefits thereunder due upon a termination of employment without cause or resignation for good reason in connection with a change in control, the definition of "change in control" will be deemed to include a transaction whereby any person (or group of persons) directly or indirectly acquires beneficial ownership of our securities representing 40% or more of the total combined voting power of our securities outstanding immediately after such transaction.

**Potential Payments upon Termination or Change in Control**

The information below describes and quantifies certain compensation and benefits that would have become payable (in certain cases subject to conditions such compliance with restrictive covenants and an effective release of claims) to each of our NEOs if our NEO's employment had terminated on December 31, 2025 (and that a Change in Control occurred on December 31, 2025, as applicable) as a result of each of the termination scenarios described below, taking into account the NEO's compensation as of that date, and reflects the acceleration benefits under the Change in Control Policy, which was adopted in February 2022. The information below does not generally reflect compensation and benefits available to all

<sup>(1)</sup> Effective December 15, 2025, Mr. Biffle was no longer Chief Executive Officer of the Company and Mr. Dempsey was appointed as the interim Chief Executive Officer for the remainder of the year. Mr. Biffle remained on the Board of Directors and employed by the Company in an advisory capacity until December 31, 2025. Effective January 7, 2026, Mr. Dempsey was appointed as the Chief Executive Officer. Mr. Biffle was paid the severance payments following the effectiveness of his release of claims in 2026. Mr. Biffle received $4,275,976 which consisted of $1,680,750, which represented one times his annual base salary plus target bonus, his 2025 bonus of $1,210,251 based on his actual performance, entitlement to continued or accelerated vesting of certain equity awards valued at $1,320,634, as discussed in footnote 8 below, and $64,341 that was intended to cover coverage pursuant to COBRA for a twelve-month period.

<sup>(2)</sup> Represents a lump sum cash payment of 12 months of base salary.

<sup>(3)</sup> Represents a lump sum cash payment of one times the NEO's target annual performance bonus amount.

<sup>(4)</sup> Represents continued coverage under COBRA for 12 months for each NEO based on the incremental cost of our contribution as of December 31, 2025 to provide this coverage. Messrs. Diamond, Mitchell, Clerc and Schroeter are not eligible for continued Company-paid coverage under COBRA.

**EXECUTIVE COMPENSATION TABLES (continued)**

<sup>(7)</sup> Represents a lump sum cash payment of two times a NEO's target annual performance bonus amount. In addition, for Mr. Dempsey, represents a pro-rated annual performance bonus for the year in which the termination occurs (based on actual performance and payable at the same time as other continuing executives) in the event of a termination without Cause or for Good Reason. For Mr. Dempsey, we included the full bonus amount paid for fiscal year 2025 under the Management Bonus Plan since the assumed termination date would be December 31, 2025.

<sup>(8)</sup> Represents the aggregate value of the pro-rated portion (based on the portion of the performance period that the participant remained in service) of Mr. Biffle's, Mr. Dempsey's, Mr. Diamond's, Mr. Mitchell's, Mr. Clerc's and Mr. Schroeter's PSUs that would be eligible to vest based on the actual achievement of the goals as of the end of the performance period in the event of a termination without Cause or for Good Reason or due to death or Disability during the performance period. The values of the PSUs shown in the table above are based on the target attainment level for the non-market PSUs based on the closing trading price of our common stock of $4.71 as of December 31, 2025 and Monte-Carlo simulation for the market PSUs, as of December 31, 2025. In the case of Mr. Biffle, the amount in the table above also captures the value of the vesting of the tranche of Mr. Biffle's RSUs that were scheduled to vest in February 2026 (based on the closing trading price of our common stock as of such date of vesting) which the Company permitted that he continue to vest into given that he had remained in service during a substantial part of the vesting period.

<sup>(9)</sup> Represents the aggregate value of Mr. Dempsey's, Mr. Diamond's, Mr. Mitchell's, Mr. Clerc's and Mr. Schroeter's PSUs and RSUs that would have vested on an accelerated basis immediately prior to a qualifying termination following the consummation of a Change in Control. The values of the RSUs shown in the table above are based on the closing trading price of our common stock of $4.71 as of December 31, 2025. The values of the PSUs shown in the table above are based on the target attainment level for the non-market PSUs based on the closing trading price of our common stock of $4.71 as of December 31, 2025 and Monte-Carlo simulation for the market PSUs as of December 31, 2025. As disclosed above, under the 2021 Plan, the awards granted under that plan will fully accelerate on a Change in Control if not assumed or substituted. Additionally, the agreements for PSUs and RSUs granted under the 2021 Plan subsequent to October 2023 provide for full acceleration on a termination without Cause (or in the case of the PSUs, a termination without Cause or for Good Reason) within 12 months following a Change in Control.

<sup>(10)</sup> Represents continued coverage under COBRA for 24 months for each NEO based on the incremental cost of our contribution as of December 31, 2025 to provide this coverage. Messrs. Diamond, Mitchell, Clerc and Schroeter are not eligible for continued Company-paid coverage under COBRA.

<sup>(11)</sup> Represents the value of continued UATP flight benefits for two years following the NEOs' termination of employment, within 12 months following a Change in Control, which must be used in the two years following termination, based on the values each NEO was eligible to receive under the UATP for fiscal 2025.

**EXECUTIVE COMPENSATION TABLES (continued)**

**CEO Pay Ratio**

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing information about the relationship of the annual total compensation of our employees and the annual total compensation of our Chief Executive Officer.

For the year ended December 31, 2025, the annual total compensation of our Chief Executive Officer, as set forth in the Summary Compensation Table, was $6,465,509 and the annual total compensation of the employee identified at median of all our employees, other than our Chief Executive Officer, was $54,000. The ratio of the annual total compensation of our Chief Executive Officer to the annual total compensation of the median employee was 120:1 (the "pay ratio").

This pay ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. As permitted by the regulation, the median employee used for 2025 is the same employee identified for 2024 because we determined that there have been no changes in our employee population or employee compensation arrangements during 2025 that would significantly impact our pay ratio disclosure.

We determined the annual total compensation of the median employee using W-2 reportable wages as of December 14, 2025, the last day that Mr. Biffle served as our Chief Executive Officer during 2025. The annual total compensation of the median employee and the annual total compensation of the Chief Executive Officer were calculated in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K.

The SEC's rules for identifying the median compensated employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own pay ratios.

<sup>(3)</sup> Fair value or change in fair value, as applicable, of equity awards in the "Compensation Actually Paid" columns was determined by reference to (i) for RSU awards, the closing price per share on the applicable year-end date(s) or, in the case of vesting dates, the closing price per share on the applicable date(s); (ii) for stock options, a Black-Scholes value as of the applicable year-end or vesting date(s), determined based on the same methodology as used to determine grant date fair value but using the closing stock price on the applicable revaluation date as the current market price and with an expected life equal to the original ratio of expected life relative to the ten-year contractual life multiplied times the remaining life as of the applicable revaluation date, and in all cases based on volatility and risk free rates determined as of the revaluation date based on the expected life period and based on an expected dividend rate of 0%; and (iii) for PSU awards, were valued dependent upon the type of award: non-market and market. The fair value of the awards subject to non-market metrics were valued using the probability of attainment of the goals and the share price of the Company's stock and for market awards were valued using the Monte Carlo simulation model, in such case, determined as of the applicable year-end or vesting date(s). A Monte Carlo simulation model uses stock price volatility and other variables to estimate the probability of satisfying the performance conditions and the resulting fair value of the award.

<sup>(4)</sup> For the relevant fiscal year, represents the cumulative TSR (the "Peer Group TSR") of the NYSE ARCA Airline Index (XAL) (the "Peer Group").

<sup>(5)</sup> The "measurement period" for each of these values is the period beginning at the "measurement point," which is the date of our IPO on April 1, 2021, through the end of the most recent fiscal year.

<sup>(6)</sup> Adjusted Pre-Tax Margin is a non-GAAP measure and represents pre-tax income (loss), adjusted for special items, divided by revenues. The sum of these non-GAAP adjustments is referred to as the "pre-tax impact." There were no adjustments to pre-tax income (loss) in 2025 and therefore our adjusted pre-tax income (loss) is equal to pre-tax income (loss) which is a GAAP measure. See Appendix A for a reconciliation of adjusted pre-tax income (loss) to the corresponding GAAP measure as well as the calculation of Adjusted Pre-Tax Margin for each year presented. While we use numerous financial and non-financial performance measures to evaluate performance under our compensation programs, Adjusted Pre-Tax Margin is the financial performance measure that, in our assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used to link CAP to our NEOs to our performance. We believe it is a useful indicator to compare the profitability of our business against industry peers of different sizes and derivations of pre-tax income (loss) are well-recognized performance measurements in the airline industry that are frequently used by our management, as well as by investors. Adjusted Pre-Tax Margin is not determined in accordance with GAAP, may not be comparable across all carriers, and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.

The Compensation Committee concluded that our compensation policies and practices do not create risks that are reasonably likely to have a material adverse effect on us.

**SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT**

The following table sets forth information with respect to the beneficial ownership of our common stock as of March 20, 2026, for:

• each person known by us to beneficially own more than 5% of our common stock;

• each of our directors and director nominees;

• each of our NEOs; and

• all of our executive officers, directors, and director nominees as a group.

The number of shares beneficially owned by each stockholder as described herein are determined under rules issued by the SEC. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of common stock subject to options, warrants, or other rights held by such person that are currently exercisable or will become exercisable within 60 days of March 20, 2026 are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person. The applicable percentage ownership is based on 229,663,349 shares of our common stock outstanding as of March 20, 2026.

Unless otherwise indicated, the address of all listed stockholders is c/o Frontier Group Holdings, Inc., 4545 Airport Way, Denver, CO 80239. The information provided in the table is based on our records, information filed with the SEC, and information provided to us, except where otherwise noted.

**Delinquent Section 16(a) Reports**

Section 16(a) of the Exchange Act requires our officers and directors, and persons who own more than ten percent of any registered class of our equity securities ("10% stockholders"), to file reports of ownership and changes in ownership with the SEC. Such officers, directors, and 10% stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) reports they file.

Based solely on our review of copies of the reports filed with the SEC and the written representations of our officers and directors, we believe that all Section 16(a) reporting requirements for fiscal year 2025 were complied with on a timely basis by each person who at any time during the 2025 fiscal year was an officer, director or 10% stockholder except for the following: Mr. Clerc filed a late Form 4 on September 12, 2025 to report the sale of common stock on September 9, 2025.

**CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS**

The following includes a summary of transactions since January 1, 2025 and any currently proposed transactions to which we were or are expected to be a participant in which (i) the amount involved exceeded or will exceed $120,000 and (ii) any of our directors, executive officers, or holders of more than 5% of our capital stock, or any affiliate or member of the immediate family of the foregoing persons, had or will have a direct or indirect material interest, other than compensation and other arrangements that are described under the sections titled "Compensation Discussion and Analysis" and "Executive Compensation Tables."

**Management Services**

In December 2013, we entered into a Professional Services Agreement with Indigo Partners, pursuant to which Indigo Partners agreed to provide our Board and our management with financial and management consulting services, including with respect to business strategy, budgeting of future corporate investments, acquisition and divestiture strategies, and debt and equity financing consulting services. In exchange for these services, we are assessed a fixed quarterly fee of $375,000 by Indigo Partners and reimburse Indigo Partners for out-of-pocket expenses incurred in connection with the rendering of services pursuant to the Professional Services Agreement. Additionally, we pay the annual fees of each member of our Board that is affiliated with Indigo Partners. We incurred an aggregate of approximately $2 million in expenses for the year ended December 31, 2025 relating to the quarterly fees, which are included as other operating expenses within our consolidated statements of operation.

In addition, we have agreed to indemnify Indigo Partners and its affiliates for losses arising from or relating to the services provided pursuant to the Professional Services Agreement. Our engagement of Indigo Partners pursuant to the Professional Services Agreement will continue until the date that Indigo Partners and its affiliates own less than 10% of the 197.6 million shares of our common stock acquired by an affiliate of Indigo Partners in December 2013.

**Registration Rights Agreement**

In April 2021, in connection with the IPO, we entered into a Registration Rights Agreement with Indigo Frontier. Following the Share Distribution, recipients of shares from Indigo Frontier may request that we initiate up to eight registrations of its shares on Form S-1 or any similar or successor long-form registration and, if available, an unlimited number of registrations of its shares on Form S-3 or any successor or similar short-form registration. Also, at any time that we propose to register any of our securities under the Securities Act, the parties to the Registration Rights Agreement will be entitled to certain "piggyback" registration rights allowing such parties to include their shares in such registration, subject to certain marketing and other limitations. In addition, we will pay all registration expenses, including the legal fees of one counsel for all holders under the Registration Rights Agreement. The Registration Rights Agreement also contains customary indemnification and contribution provisions.

**Director and Officer Indemnification and Insurance**

Our amended and restated certificate of incorporation and Bylaws provide indemnification and advancement of expenses for our directors and officers to the fullest extent permitted by the Delaware General Corporation Law, subject to certain limited exceptions. In connection with our initial public offering, we entered into separate indemnification agreements with each of our directors and executive officers. We have also purchased directors' and officers' liability insurance for each of our directors and executive officers.

**Codeshare Arrangement**

In January 2018, we entered into a codeshare agreement with Controladora Vuela Compañía de Aviación, S.A.B. de C.V. (an airline based in Mexico doing business as "Volaris"). As of December 31, 2025, two of our directors, Andrew S. Broderick and Brian H. Franke, are members of the board of directors of Volaris, with Brian H. Franke serving as chair since April 2020. In addition, one of our directors, William A. Franke, is an honorary director for Volaris. In August 2018, we and Volaris began operating scheduled codeshare flights. Each party bears its own costs and expenses of performance under the codeshare agreement. The codeshare agreement is subject to automatic renewals and may be terminated by either party at any time upon the satisfaction of certain conditions.

**CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS (continued)**

**Our Policy Regarding Related Party Transactions**

Our Board has adopted a written related party transaction policy setting forth the policies and procedures for the review and approval or ratification of related party transactions. This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act, any transaction, arrangement, or relationship, or any series of similar transactions, arrangements, or relationships in which we were or are to be a participant, where the amount involved exceeds $120,000 in any one fiscal year and a related party had or will have a direct or indirect material interest. Our Audit Committee must review the relevant facts and circumstances of each related party transaction, including if the transaction is on terms comparable to those that could be obtained in arm's length dealings with an unrelated third-party and the extent of the related person's interest in the transaction, take into account the conflicts of interest and corporate opportunity provisions of our Code of Conduct, and either approve or disapprove the related party transaction. If advance Audit Committee approval of a related party transaction requiring the Audit Committee's approval is not feasible, then the transaction may be preliminarily entered into by management upon prior approval of the transaction by the Chair of the Audit Committee subject to ratification of the transaction by the Audit Committee at the Audit Committee's next regularly scheduled meeting; provided, that if ratification is not forthcoming, management will make all reasonable efforts to cancel or annul the transaction. No director may participate in approval of a related person transaction for which he or she is a related person.

**ADDITIONAL INFORMATION**

**Stockholder Proposals**

Stockholders who intend to have a proposal considered for inclusion in our proxy materials for presentation at our 2027 annual meeting of stockholders pursuant to Rule 14a-8 under the Exchange Act must submit the proposal to us at our principal executive offices, 4545 Airport Way, Denver, CO 80239. Any proposal submitted pursuant to Rule 14a-8 must be received by us no later than December 3, 2026. We suggest that proponents submit their Rule 14a-8 proposals by certified mail, return receipt requested, addressed to our Executive Vice President, Legal and Corporate Affairs. In connection with our 2027 annual meeting of stockholders, we intend to file a proxy statement and a WHITE proxy card with the SEC in connection with our solicitation of proxies for that meeting.

In addition, our Bylaws establish an advance notice procedure with regard to director nominations and other proposals by stockholders that are not intended to be included in our proxy materials, but that a stockholder instead wishes to present directly at an annual meeting. To be properly brought before the 2027 annual meeting of stockholders, a notice of the nomination or the matter the stockholder wishes to present at the meeting must be in writing and delivered to or mailed and received by our Executive Vice President, Legal and Corporate Affairs at our principal executive offices not later than the end of the day on February 13, 2027 and not before the opening of business on January 14, 2027. However, if the 2027 annual meeting of stockholders is more than 30 days before or 60 days after the first anniversary of the 2026 Annual Meeting, notice must be so delivered or received not later than the close of business on the 90th day prior to such annual meeting, or, if later, the 10th day following the date on which public disclosure of the date of such annual meeting was first made. Our Bylaws also specify requirements relating to the content of the notice that stockholders must provide in order for a director nomination or other proposal to be properly presented at the 2027 annual meeting of stockholders.

Any notice of director nomination must include the additional information required by Rule 14a-19(b) under the Exchange Act and otherwise comply with our Bylaws.

**Householding of Annual Meeting Materials**

The SEC's rules permit us to deliver a single set of proxy materials to one address shared by two or more of our stockholders. This delivery method is referred to as "householding" and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the proxy materials, as requested, to any stockholder at the shared address to which a single copy of those documents was delivered. If you prefer to receive separate copies of the proxy materials, contact Broadridge Financial Solutions, Inc. at 1-866-540-7095 or in writing at Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717.

If you are currently a stockholder sharing an address with another stockholder and wish to receive only one copy of future proxy materials for your household, please contact Broadridge at the above phone number or address.

**Solicitation of Proxies**

The accompanying proxy is solicited by and on behalf of our Board, whose notice of meeting is attached to this proxy statement, and the entire cost of such solicitation will be borne by us.

In addition to the use of the mail, proxies may be solicited by personal interview, telephone, and email by directors, officers, and other employees of Frontier Group Holdings, Inc. who will not be specially compensated for these services. We will also request that brokers, nominees, custodians, and other fiduciaries forward soliciting materials to the beneficial owners of shares held of record by such brokers, nominees, custodians, and other fiduciaries. We will reimburse such persons for their reasonable expenses in connection therewith.

**2025 Annual Report**

We will furnish, without charge, a copy of our 2025 Annual Report, including consolidated financial statements but not including exhibits, to each of our stockholders of record on March 27, 2026, and to each beneficial stockholder on that date upon written request addressed to: Howard Diamond, Executive Vice President, Legal and Corporate Affairs, Frontier
