Republic’s development of long-term relationships with multiple major airlines has enabled Republic to diversify its revenue base and to reduce Republic’s dependence on any single, mainline customer. For the year ended December 31, 2025, Republic’s departures for American Airlines, Delta Air Lines, and United Airlines were divided in the following proportions:

Due to the merger of Republic Airways Holdings Inc. and Mesa Air Group, Inc., whereby the Company merged with and into Mesa Air Group, Inc. (the “Merger”) in November 2025, Republic expects its departures to increase

significantly in 2026. The Company expects an approximate increase of 24% block hours during the year ending December 31, 2026.

The Essential Role of Regional Airlines

Regional airlines play an essential, daily role in the U.S. airline industry and constitute the only local access point to the global air travel system for hundreds of U.S. cities. According to the Regional Airline Association (“RAA”), 32% of all scheduled airline flights in the United States in 2024 were performed by regional airlines, and approximately 134 million passengers were carried on those flights. Of the U.S. airports with scheduled passenger service, 64% are served exclusively by regional airlines.

Regional airlines work in close cooperation with their major airline partners, rather than in competition with them. Like many large organizations, the U.S. major airlines outsource certain operating functions to independent providers that demonstrate outstanding specialization and cost-efficiency in their respective functional areas. Examples include payroll processing, call center operations, and aircraft maintenance, among others. Among the most visible and commercially important of these outsourced functions is the job of providing safe, clean, reliable, and efficiently scheduled flights for the millions of passengers each year who travel between small markets and the large-market hubs of the major airlines. Republic believes few major airline hubs would be viable today without the regional airline flights that build schedule density and transport passenger traffic to the hub.

The vast majority of regional flying in the United States today is performed under CPAs. Republic’s CPAs stipulate that Republic operates flights under the Partner Airlines’ two-letter flight designation codes (also known as “code-sharing”), paint Republic’s aircraft in the style of the Partner Airlines, and otherwise use the Partner Airlines’ American Eagle, Delta Connection, or United Express branding elements. the Partner Airlines control route selection, pricing, marketing, and scheduling and provide Republic with fuel, ground support services, airport landing slots, and gate access, allowing Republic to focus all of its efforts on delivering safe, clean, and reliable regional service. the Partner Airlines retain all the revenue from the passengers and cargo aboard Republic’s flights and, in exchange, pay Republic the fixed amounts specified under Republic’s CPAs. Republic benefits because Republic’s CPAs shelter Republic from many of the elements that cause volatility in airline financial performance, including fuel prices, variations in ticket prices, and passenger load factors.

Republic’s Strengths

Republic believes the following strengths create competitive advantages that make Republic an employer of choice for airline professionals starting their careers and a key strategic partner for the Partner Airlines:

Long-Duration Contracts with Three Major Airlines. Republic’s contracts have individual aircraft expirations ranging from 2026 into the late 2030s, and Republic’s average contract expiration is in October 2031. Republic’s contracts provide for minimum aircraft utilization levels, fixed payments per month for each aircraft under contract, fixed payments for each block hour or flight performed, provision of fuel by the Partner Airlines, and reimbursement of certain direct operating expenses, such as insurance and aircraft property taxes. Having the three Partner Airlines has allowed Republic to diversify its financial and operational risk. Republic believes this diversity allows it to not be limited by the rate at which any one of the Partner Airlines can, or wishes to, grow. By flying for different Partner Airlines, Republic is also able to leverage the cost of Republic’s overhead expenses across multiple parties. If travel demand should be interrupted or follow an unexpected pattern, Republic’s CPA contracts still afford Republic better revenue visibility and downside protection than air carriers that have full exposure to adverse movements in passenger load factors, fuel prices, and airfares.

Republic Airways has maintained a partnership with American Airlines and its predecessors for more than 50 years, which Republic believes is a result of Republic’s distinct focus on operational excellence. Republic Airways subsequently expanded its partnership reach to Delta Air Lines in 2002 and United Airlines in 2004 and have operated under the same mission of unparalleled service each year. Mesa has maintained a partnership with United Airlines since 1990. Additionally, Republic’s commitment to safety is experienced by Republic’s passengers every day and Republic has a perfect passenger safety record over Republic’s 50-year history of operating commercial aircraft.

Operational Excellence and Reliability. During the year ended December 31, 2025, Republic completed 99.99% of its flights adjusting for weather and other non-controllable events, which Republic defines as controllable completion factor (“CCF”). Despite Republic’s contracted routes being concentrated in regions which experience severe air traffic congestion and weather-related disruptions, Republic has continued to be a leading performer in the industry in terms of on-time arrival performance. Republic believes that the amount charged to the Partner Airlines for services and Republic’s ability to reliably operate regional jet flights are the two most important factors weighed by the Partner Airlines in awarding new flying contracts, and that Republic’s completion percentage is a significant factor in assessing Republic’s reliability. Because Republic operates in some of the most logistically challenging air spaces for the Partner Airlines, any operational issue affects a series of connecting flights, and therefore the Partner Airlines value Republic’s reliability more in these locations than in less congested airports.

Financial Strength and Risk Management. As of December 31, 2025, Republic had total cash, cash equivalents, restricted cash, and marketable securities of $319.9 million, equivalent to approximately 19% of Republic’s 2025 annual revenues, and $1,225.3 million of total debt and lease obligations (operating and financing leases). Approximately 93% of Republic’s aircraft and engine debt is comprised of aircraft and engine mortgages with maturities that closely match their respective original CPA expiries. Provided Republic performs to satisfactory operational levels and no Partner default occurs, the payments received under Republic’s CPAs are structured to cover the mortgage principal and interest payments, and to reduce mortgage principal balances to zero by the end of the initial CPA term. Republic owns outright 33% of its aircraft fleet and expects to own 49% of the fleet by the end of 2028. Republic believes its prudent financial management and strong balance sheet will allow Republic to aggressively pursue opportunities to expand its flying as opportunities become available.

Strong Culture Drives Recruitment and Retention. Since inception, Republic has built a reputation as the employer and career path of choice for aviation professionals. Current staffing levels should position Republic for future growth opportunities.

Republic believes there are several qualitative factors that contribute to Republic’s success in pilot, flight attendant, maintenance technician, and dispatcher recruitment and retention:

•Attractive Culture: Republic believes it offers a positive work environment and culture for its employees, and strives to provide a favorable quality of life. For example, Republic has made significant investments in proprietary technology, including in its mobile application, to ensure Republic can take action to quickly recover from irregular operations, such as by finding alternative routes, crews, and hotel accommodations.

•Training Focus: Republic opened a new state-of-the-art aviation campus in 2023 that provides an inclusive campus atmosphere with a dedicated facility to provide overnight accommodations. The new campus provides training for Republic’s pilots, flight attendants, maintenance technicians, and dispatchers, which Republic believes sets Republic apart from its competition and assists in attracting new aviation professionals to the industry.

•Career Advancement Opportunities: Republic provides its employees exposure to all three of the Partner Airlines’ airline networks and believes its employees value this broad exposure since it may lead to placement advantages for those ultimately looking to progress from Republic to American Airlines, Delta Air Lines, or United Airlines. Republic only flies large, dual class regional jets with advanced flight deck avionics, which Republic believes aviation professionals hold in high regard due to their performance and comfort.

•Favorable Contracts: Republic Airways has CBAs with its pilots, flight attendants, and dispatchers. Mesa Airlines has CBAs with its pilots and flight attendants. Republic believes its CBAs are among the most favorable in the industry in terms of the wages and benefits offered.

Republic’s Strategy

Republic’s business strategy consists of the following principal elements:

CPA Flying Only. Substantially all of Republic’s regional flying is performed under CPAs, which is a low risk business model due to guaranteed levels of operations.

Positioning Republic for Future Growth. Republic regularly engages with the Partner Airlines to anticipate their long-term regional capacity requirements and to support their regional airline capacity needs as they adapt or enter into new markets. Republic believes that future regional aircraft flying opportunities will be awarded to the regional airlines demonstrating outstanding operational reliability at an efficient cost and an ability to staff the flying commitment. Republic intends to compete aggressively for opportunities to expand its base of CPA flying.

Focus on Complementary Aircraft Types. All of Republic’s operating regional jet aircraft are dual class Embraer E170/175 aircraft. Republic has significant experience with operating dual class regional aircraft and will consider organic growth opportunities that would allow Republic to operate other large, dual class regional aircraft types.

Emphasize Quality Service. Safety, reliability, and passenger service are at the core of Republic’s business strategy. Republic believes providing superior performance to the Partner Airlines will make Republic a preferred alternative when the Partner Airlines develop requirements for additional regional flying or seek to reallocate existing regional flying from one provider to another. Republic focuses on providing excellent passenger service through well-trained personnel, clean aircraft, consistent in-flight amenities, and on-time performance. Republic’s operational excellence is exemplified by its flight completion factors and ability to quickly recover following inclement weather events. Republic believes its CCF of 99.99% for the year ended December 31, 2025 is particularly notable given the concentration of Republic’s flight routes at logistically challenging airports. Republic believes its focus on passenger service, cleanliness, safety, and reliability helps the Partner Airlines build customer loyalty and compete better in their own right.

Differentiated Pilot Development and Other Career Opportunities. Republic’s ability to recruit and retain pilots has been key to Republic’s business. Republic intends to continue to offer competitive compensation packages, foster a positive work environment, and provide opportunities to fly state-of-the-art, large, dual class regional jets to differentiate Republic from other regional carriers and make Republic an attractive place to work and build a career. For pilot associates seeking to shift to careers at major airlines, Republic believes the quality of experience obtained at Republic, including the opportunity to fly for all three major carriers, raises Republic’s pilots likelihood of moving directly to their preferred air carrier.

Republic believes it has a distinct competitive advantage in its ability to train pilots in a single location at Republic’s state-of-the-art aviation campus that provides necessary flight instruction and flight simulator time, including full motion simulators.

In addition, Republic believes it is leading the industry in its strategic approach to attracting and developing new pilots, technicians, and dispatchers. Republic works with over 20 flight training programs across the country for recruitment, has established more than 25 meaningful partnerships with colleges and flight schools for hiring pathways, and owns one of the only proprietary flight schools in the regional airline industry, LIFT Academy, based in Indianapolis, Indiana. LIFT Academy’s mission is to attract a new generation of aviation professionals to flight careers by providing superior flight training while addressing the economic and structural barriers to entry. The program is structured so that LIFT Academy graduates will have a defined career pathway to being a First Officer with Republic. In addition, Republic secured a partnership with Hyannis Air Service Inc. d/b/a Cape Air and Nantucket Airlines (“Cape Air”) to create a flow program of talented aviators from LIFT Academy to Cape Air to supplement their workforce in exchange for flight hours and valuable experience. This creates a stronger pathway for both airlines. Since its founding in 2018, LIFT Academy has expanded its operations with additional flight school locations in Columbia, S.C, Myrtle Beach, SC, Galveston, TX, Columbus, IN, and at Moton Field in partnership with Tuskegee University in Tuskegee, AL. In return for the high-quality training Republic provides, LIFT graduates will contractually commit to work at Republic for at least five years or at least two years as a Captain upon graduation. LIFT Academy admitted its first class of students in September 2018 and has the

6

Table of Contents

potential to train over 500 students each year. With the Merger with Mesa, Republic acquired Bridge Air (formerly Mesa Pilot Development Program) which provides a low-cost option for pilots needing the FAA minimum hour requirement by flying designated missions to work for airlines such as Republic Airways or Mesa Airlines.

Both Republic Airways and LIFT Academy offer an Aviation Maintenance Technician (“AMT”) Apprenticeship Program in partnership with the U.S. Department of Labor (“DOL”) to provide hands-on training and one-on-one instruction with Republic and LIFT Academy licensed maintenance technicians for individuals seeking employment as licensed AMTs with Republic. The program takes less than three years to complete, and upon completion of their training and successful Airframe and Powerplant (“A&P”) examinations, AMT apprentices have a direct pathway to a career at Republic. To address dispatcher development, Republic has created an aircraft dispatcher apprenticeship program that allows individuals with little or no airline experience to train in a six-to-eight-week paid program to learn the skills and knowledge required to become a Federal Aviation Administration (“FAA”) certified aircraft dispatcher.

In addition, Republic has a partnership with Ivy Tech Community College to support full-time associates who have not yet attained a college degree or a professional certification. For eligible associates, Republic contributes a portion of tuition towards eligible associate degree and certificate programs each year.

Continue to Develop Republic’s Aircraft Platform. Republic intends to continue to focus its operations on the most modern, large, dual class regional jets. In anticipation of long-term fleet replacement needs and the potential to capture additional regional flying, Republic has an order for 29 Embraer regional jets (E175), and expects three aircraft to be delivered during the three months ended March 31, 2026, with the 26 remaining deliveries scheduled for delivery in 2027 through 2029. Republic believes the use of larger, dual class regional jets allows Republic to offer a higher quality service to the Partner Airlines without incurring increased operating costs relative to its competitors.

Markets and Routes

Markets

Republic provides scheduled passenger service on approximately 1,300 flights daily to approximately 130 cities in the United States, Canada, Mexico, and the Caribbean.

The following map illustrates the routes Republic flies for Republic’s Partner Airlines:

Capacity Purchase Agreements with the Partner Airlines

Republic’s fixed-fee CPAs are structured so that revenues are generally derived from (i) a fixed fee per departure, flight hour, and/or block hour of time incurred in addition to overall aircraft in service and aircraft per day fees, payable on a monthly basis, and (ii) a premium amount, which is earned by maintaining a minimum aircraft utilization and exemplary operating results. These rates are generally subject to periodic economic adjustment. Republic additionally receives reimbursement from its Partner Airlines for direct expenses incurred in operations, such as qualifying maintenance activities, aircraft insurance, and property taxes. Republic refers to Partner reimbursements as “pass-through” charges. Certain charges such as fuel, landing fees, and certain ownership costs, are paid directly by the Partner Airlines, although the charges were incurred by Republic in its ongoing operations. Republic refers to these charges as “Partner direct charges.”

Pursuant to Republic’s CPAs, Republic provides passenger service on behalf of American Airlines, Delta Air Lines, and United Airlines, and Republic is authorized to use the Partner Airlines’ two-character flight designator codes (American Airlines—“AA,” Delta Air Lines—“DL,” and United Airlines—“UA”) to identify Republic’s flights directly within each Partner’s reservation systems and to outfit Republic’s interior and exterior aircraft livery with the Partner Airlines’ colors, logos, and service marks, allowing for joint marketing of Republic’s flights by Republic and each of the Partner Airlines. Passenger tickets are issued by each of the Partner Airlines, who therefore bear the risk associated with fare competition and management of seat inventory. In addition, under Republic’s fixed-fee CPAs with American Airlines, Delta Air Lines, and United Airlines, Republic’s passengers are eligible for participation in the Partner Airlines’ frequent flyer loyalty programs: AAdvantage®, SkyMiles®, and MileagePlus®, respectively. Support services such as reservations, ticketing, ground handling services, baggage handling, fuel procurement, commuter slot rights, and airport facilities, among others, are additionally provided by the Partner Airlines. Significant provisions in Republic’s CPAs, which are amended from time to time, are discussed below.

United Airlines

As of December 31, 2025, Republic had 126 aircraft under operation for United Airlines.

The Company entered into a CPA with United Airlines during the year ended December 31, 2021, for the replacement of 38 E170 aircraft with new E175 aircraft for scheduled passenger service over a 12-year term, including certain customary right-of-use aircraft leasing terms. The Company placed 34 aircraft into service since inception of the CPA. Additionally, the Company further repositioned 34 E170 aircraft from the United Airlines CPAs based on scheduled United Airlines CPA expiries during the years then ended. The remaining four aircraft are expected to be operating on the United Airlines CPA during the year ending December 31, 2026, which includes one aircraft delivered during the year ended December 31, 2025, which had not yet commenced revenue service.

Further, on November 25, 2025, in connection with the Merger, the Company entered into a new 10-year CPA with United Airlines and Mesa, to operate an additional 60 E175 aircraft owned by United Airlines and operated by Mesa Airlines, Inc.

All of Republic’s leased aircraft are leased pursuant to finance leases, with current lease expirations ranging from 2030 to 2031.

From time to time, Republic enters into purchase commitments for future aircraft and engine deliveries. The Company regularly makes pre-delivery deposit payments (“PDPs”) to support aircraft and engines on order. PDPs are retained and applied against the historical cost of the corresponding aircraft or engine at the time of its acquisition or expensed when deposit amounts are no longer expected to be returned from the manufacturer.

Republic has an order for 29 Embraer regional jets (E175), and expects three aircraft to be delivered during the three months ended March 31, 2026, with the remaining 26 aircraft deliveries beginning in 2027 through 2029.

Employees and Collective Bargaining Agreements (“CBAs”)

As of December 31, 2025, Republic employed approximately 8,400 employees. Of Republic’s total headcount, approximately 71% of employees are represented by CBAs as follows:

Collective bargaining agreements between the Company and each of IBT, Local 357; IBT, Local 135; Association of Flight Attendants and TWU, Local 592 become amendable during the year ending December 31, 2027. The CBA between Mesa Airlines and ALPA is currently amendable.

Although the Company has never had a work interruption or stoppage, the Company is subject to risks of work interruption or stoppage. Such conditions would materially impact the Company’s financial position, results of operations and cash flows, should they occur.

The Railway Labor Act (“RLA”) governs Republic’s relations with labor organizations. Under the RLA, CBAs generally do not expire but instead become amendable as of a stated date. If either party wishes to modify the terms of any such agreement, they must notify the other party in an agreed-upon manner. After receipt of such notice, the parties must meet for direct negotiations, and if no agreement is reached, either party may request that the National Mediation Board (“NMB”) appoints a Federal mediator. The RLA prescribes no set timetable for the direct negotiation and mediation process. It is not unusual for those processes to last for many months, extending into years. If no agreement is reached in mediation, the NMB in its discretion may declare at some time that an impasse exists, and if an impasse is declared, the NMB proffers binding arbitration to the parties. Either party may decline to submit to arbitration. If arbitration is rejected by either party, a

11

Table of Contents

30-day “cooling off” period commences. During that period (or after), a Presidential Emergency Board (“PEB”) may be established, which examines the parties’ positions and recommends a solution. The PEB process lasts for 30 days and is followed by another “cooling off” period of 30 days. At the end of a “cooling off” period, unless an agreement is reached, or action is taken by Congress, the labor organization may strike, and the airline may resort to “self-help,” including the imposition of any or all of its proposed amendments and the hiring of new employees to replace any striking workers. Congress and the President have the authority to prevent “self-help” by enacting legislation that, among other things, imposes a settlement on the parties.

The FAA regulations require pilots to have an Air Transport Pilot (“ATP”) license with specific ratings for aircraft to be flown and to be medically certified as physically fit to fly. FAA and medical certifications are subject to periodic renewal requirements, including recurrent training and recent flying experience. Maintenance technicians, quality-control inspectors, and flight dispatchers must be certificated and qualified for specific aircraft. Flight attendants must have initial and periodic competency training and qualification. Training programs are subject to approval and monitoring by the FAA. Management personnel directly involved in the supervision of flight operations, training, maintenance, and aircraft inspection must also meet experience standards prescribed by FAA regulations. All safety-sensitive employees are subject to pre-employment, random, and post-accident drug testing.

The airline industry has from time to time experienced a shortage of qualified personnel, particularly with respect to pilots and maintenance technicians. In addition, as is common with most of Republic’s competitors, Republic has faced considerable turnover of its employees. Regional pilots, flight attendants, and maintenance technicians often leave to work for larger airlines, which generally offer higher salaries and more comprehensive benefit programs than regional airlines are financially able to offer. Republic’s turnover is expected to increase when hiring expands at major carriers, cargo carriers, or low-cost carriers.

Attracting, Developing, and Retaining Talent

Recruitment Strategies

Republic strives to be the employer of choice for aviation professionals pursuing a career in the regional airline industry, and Republic continually advances its recruiting strategies to attract quality aviation professionals. Republic adapts its recruitment efforts based on the supply of eligible aviation professionals and Republic’s outlook for anticipated future flight demand. Republic’s recruiting focus generally targets key aviation technical roles, particularly pilots and maintenance technicians. Republic seeks qualified individuals throughout all positions on both internal and external career websites, supporting professional development leads, and investment in targeted advertising, social media outreach, employee referrals, and relationships with community-based organizations and educational institutions.

School Partnerships and Development

Republic prioritizes workforce development investments and maintains relationships with numerous flight schools and educational institutions across the country that are focused on developing the next generation of aviation professionals. Republic focuses recruitment efforts on pilots and maintenance technicians that have completed required coursework from an accredited flight or maintenance school, respectively, and have obtained other applicable certifications. Republic has established additional robust programs to enhance Republic’s recruiting efforts toward individuals who are new industry entrants or are in the process of completing their training, including the following programs:

•Republic owns one of the only proprietary flight schools in the regional airline industry, LIFT Academy. Republic’s mission is to attract a new generation of aviation professionals to flight and maintenance careers by providing superior aviation training, while addressing the economic and structural barriers to entry to the aviation industry. The program is structured so that LIFT Academy graduates will have a defined career pathway to become a pilot or aviation maintenance technician with Republic. In addition, Republic has secured a partnership with Cape Air to create a flow program of talented aviators from LIFT Academy to Cape Air to supplement their workforce in exchange for flight hours and valuable experience. In addition, our Bridge Air program allows for economically advantageous flight hour time building. These programs create a stronger pathway for both airlines

12

Table of Contents

and breaks down even more barriers for future aviation professionals. In return for the high-quality training Republic will provide, LIFT graduates contractually commit to working at Republic for at least five years or at least two years as a Captain upon graduation. LIFT Academy has the potential to train over 500 students each year.

•Republic works with more than 20 flight training programs across the country for recruitment and has established more than 25 meaningful partnerships with colleges and flight schools for hiring pathways. The purpose of these partnerships is to increase Republic’s access to qualified applicants for employment and to increase employment opportunities for students who attend these programs. These partnerships will have access to the preferential interview process for the respective schools’ students and marketing rights for both the flight school/university and Republic. The Partner Airlines are also invited to attend its annual faculty/staff roundtable, allowing for industry and academia to partner and remain apprised of the continuous changes in commercial aviation.

•The Pilot Ambassador Program is currently staffed by approximately 75 flight students and instructors, representing flight and educational institutions throughout the country. Selected students partner with Republic to serve as brand ambassadors on their respective campuses and are consistent and on-site resources for their peers who are interested in employment with us. Ambassadors play a key role in the pipeline of Republic’s RJET Cadet Program. Each Ambassador has a conditional employment offer and will join Republic as a First Officer upon completion of their flight training requirements.

•The RJET Cadet Program is a pathway from classroom to flight deck for all flight school students. Students currently attending a flight school can interview with Republic for a conditional employment offer for a pilot position following the completion of their instrument certification. Republic has over 1,000 students enrolled in the Cadet program. Each student holds a conditional offer of employment to join Republic as a pilot upon completion of their flight training requirements.

•The AMT Apprenticeship Program provides a career path for individuals seeking employment as licensed AMTs with us. In this DOL certified program, participants “earn while they learn,” and are compensated while they complete on-the-job training alongside licensed professionals over the course of 30 months. Upon completion of their training and successful A&P examinations, AMT apprentices have a direct pathway to a career at Republic. Republic offers a similar program through LIFT Academy with training alongside LIFT licensed maintenance professionals.

On-going Training and Retention

Republic invests in retaining its professionals by providing a range of talent development opportunities, including mandatory compliance training, new hire training, and general professional development, as well as engaging in the training of leaders through leadership development courses. Republic’s training programs include full-motion flight simulators for pilots, cabin trainers for flight attendants, and on-the-job training for Republic’s maintenance technicians. In 2023, Republic completed a state-of-the-art aviation campus that houses simulators, cabin trainers, and classrooms to train its pilots, flight attendants, maintenance technicians, dispatchers, and other employees. Republic also reinforces its guiding principles, as well as through Republic’s employee appreciation and recognition programs. These programs are intentionally built upon Republic’s guiding principles: to be good stewards of Republic’s resources, to encourage a culture of fun and action, to strive for excellence in everything Republic does, and to trust, respect, and care for one another.

Total Rewards

Republic operates in a customer-focused, team-based environment and provides opportunities for dedicated individuals to develop their careers, while receiving competitive compensation, benefits, and rewards. Republic’s employees receive several compensation benefits, including but not limited to:

•Competitive wages and incentives based on Republic’s operating and financial performance goals.

•Multiple insurance options, including health care and life insurance.

•Access to retirement savings plans with matching contributions.

•Employee assistance programs, which include confidential counseling services.

•A variety of resources that allow for scheduling flexibility with paid time off from work.

•Space-available travel privilege program for employees and eligible family members through the Partner Airlines.

•Access to financial wellness programs, continuing education partnerships, and other work-life effectiveness programs.

Employee Reporting

Republic’s Code of Conduct contains general guidelines for conducting business in an ethical manner. Republic is committed to a working environment that is safe and supports open and honest communication. Republic has established a reporting system for any employee to report a violation of Republic’s policy, including harassment, discrimination, drug and alcohol use, fraudulent financial practices, or a breach involving safety or security. A general grievance may also be filed even if an employee has already utilized their chain of command or chooses to remain anonymous. Reports can be filed using a toll-free hotline that is published internally.

Maintenance of Aircraft and Training

Using a combination of FAA certified maintenance vendors and Republic’s own employees and facilities, Republic maintains its aircraft on a scheduled and “as-needed” basis. Republic emphasizes preventive maintenance and inspects its aircraft engines and airframes, as required by FAA regulation to enhance reliability and avoid excess costs from the avoidance of irregular operation events.

Under Republic’s maintenance agreements, Republic is charged for covered services based on a fixed rate for each flight hour or flight cycle accumulated by the engines or airframes in service each month. Rates are subject to annual revisions, generally based on certain inflation indices published by the DOL Bureau of Labor Statistics. Republic believes its ongoing maintenance program reduces the likelihood of unexpected maintenance expense levels for its engines, avionics, wheels and brakes, and other spare parts. Certain of these agreements contain minimum guarantee amounts, penalty provisions for the early removal of aircraft, and termination for activity levels below the minimums.

Republic performs overnight maintenance at its facilities in Columbus, OH; El Paso, TX; Indianapolis, IN; Louisville, KY; Pittsburgh, PA; Houston, TX; and Dulles, VA. Republic also performs routine maintenance services from select line maintenance locations. Republic’s heavy maintenance is performed by its vendors in Windsor, Ontario, Canada; Oklahoma City, OK; and Nashville, TN.

All maintenance technicians and avionics specialists employed by Republic have appropriate training and experience and hold required licenses issued by the FAA. Republic provides periodic in-house and outside training for its maintenance and flight personnel and also takes advantage of manufacturers’ training programs that are offered when Republic acquires new aircraft.

Republic Airways owns one full-motion flight simulator, and leases seven simulators that are all housed in its state-of-the-art aviation campus in Carmel, Indiana. Mesa also has an agreement to obtain additional simulator time for up to two additional simulators located in Arizona. Republic believes its lease arrangements will be able to provide adequate and cost-effective flight simulator training for its pilots.

Safety and Security

Republic is dedicated to ensuring the safety and security of Republic’s customers and associates. Republic has taken numerous measures, both voluntarily and as required by regulatory authorities, to increase the safety and security of Republic’s operations. Republic is committed to complying with future safety and security requirements.

Table of Contents

Republic expects its employees to think, plan, communicate, and act appropriately to prevent injury, illness, or harm to themselves, fellow associates, passengers, and its aircraft.

Republic’s ongoing focus on safety relies on training its employees to proper 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 Republic’s operation including: dispatch, flight operations, in-flight, and maintenance.

The Transportation Security Administration (“TSA”) and the U.S. Customs and Border Protection (“U.S. CBP”), each a division of the U.S. Department of Homeland Security, are responsible for certain civil aviation security matters, including passenger and baggage screening at U.S. airports, and international passenger prescreening prior to entry into or departure from the United States. International flights are subject to customs, border, immigration, and similar requirements of equivalent foreign governmental agencies. Republic currently complies, in all material respects, with all directives issued by such agencies. Republic maintains active, open lines of communication with the TSA at all of its locations to ensure proper standards for security of its personnel, equipment, and facilities are exercised throughout the operation.

Competition and Economic Conditions

The airline industry is highly competitive. We compete primarily with independent and wholly-owned U.S. regional airlines that currently hold or compete for CPAs with major airlines. Republic’s competition includes nearly every other domestic regional airline, including Endeavor (wholly-owned by Delta Air Lines); Envoy, PSA, and Piedmont (each, wholly-owned by the parent company of American Airlines); and SkyWest Airlines, Inc. Certain information regarding Republic and Republic’s primary competitors, published by the RAA, is listed below:

(1)Certain smaller independent regional airlines with code-share relationships or CPAs with major airlines have been excluded due to size.

Major airlines typically offer CPAs to regional airlines on the basis of the following criteria: (i) availability of labor resources; (ii) proposed contract economic terms; (iii) reliable and on-time flight operations; (iv) corporate financial resources, including ability to procure and finance aircraft; and (v) customer service levels. Additionally, each major airline may be limited in the number and type of regional jet aircraft it may use in its network due to agreements major airlines have with their own labor groups, commonly referred to in the industry as “scope limitations.” Given the Partner Airlines’ scope limitations, Republic currently does not operate regional jet aircraft configured with more than 76 seats.

Certain of Republic’s competitors are larger and have significantly greater financial and other resources than Republic. Moreover, economic downturns combined with competitive pressures, have contributed to a number of reorganizations, bankruptcies, liquidations, and business combinations among major airlines and regional carriers in recent years. The effect of economic downturns is somewhat mitigated by Republic’s reliance on Republic’s CPAs with revenue-guarantee provisions, but the renewal and continued profitability of these partnerships with the Partner Airlines is not guaranteed. If, however, any of the Partner Airlines experience a prolonged decline in the number of passengers or are negatively affected by low ticket prices or high fuel prices, they may seek rate reductions in future CPAs, or materially reduce scheduled flights in order to reduce their costs. In addition, adverse weather conditions or air traffic controller

staffing can impact Republic’s ability to complete scheduled flights and can have a negative impact on Republic’s operations and financial condition. Also, major airline scope limitations may restrict growth opportunities for regional carriers.

Government Regulation

Aviation Regulation

The airline industry is heavily regulated, especially by the Federal government. Two of the primary regulatory authorities overseeing civil air transportation in the United States are the Department of Transportation (“DOT”), and the FAA, an organization within the DOT. The DOT and FAA have regulatory authority over air transportation to, from, and within the United States. The DOT has authority to issue certificates of public convenience and necessity, exemptions, and other economic authority required for airlines to provide interstate and foreign air transportation. International routes and international code-sharing arrangements are regulated by the DOT and by the governments of the foreign countries involved.

A U.S. airline’s ability to operate flights to and from international destinations is subject to the air transport agreements between the United States and the foreign country and the carrier’s ability to obtain the necessary authority from the DOT and the applicable foreign government. The U.S. government has negotiated “open skies” agreements with many countries, which generally allow unrestricted access between the United States and the applicable foreign country and to points beyond the foreign country on flights serving the foreign country. With certain other countries, however, the United States has a restricted air transportation agreement. Changes in the aviation policies of the United States or any foreign country that Republic serves, changes with respect to air transportation agreements, or changes in the relationship between the U.S. and a foreign country that Republic serves could result in the alteration or termination of the corresponding air transport agreement, diminish the value of Republic’s international route authorities, or otherwise affect Republic’s operations to or from these countries.

The FAA is responsible for regulating and overseeing matters relating to the safety of air carrier flight operations, including the control of navigable air space; the qualifications of flight personnel; flight training practices; pilot flight, duty, and rest requirements; compliance with FAA airline operating certificate requirements; aircraft certification, registration, inspection, and maintenance requirements; and other matters affecting air safety and operations. The FAA requires commercial airlines like Republic to obtain and hold an FAA Air Carrier Certificate. In addition, the FAA requires, among other things: operating, airworthiness, and other certifications; approval of personnel who may engage in flight maintenance or operations activities; record keeping procedures in accordance with FAA requirements; and FAA approval of flight training and retraining programs.

Generally, governmental agencies, such as the DOT and FAA, enforce their regulations through, among other mechanisms, routine audits, investigations, and proceedings, which can result in civil or criminal penalties and/or suspension or revocation of operating authority.

Republic believes that it is operating in compliance with DOT and FAA regulations, in all material respects, and holds all necessary operating and airworthiness certificates and licenses. Republic incurs substantial costs in maintaining its current certifications and otherwise complying with the laws, rules, and regulations to which Republic is subject. Republic’s flight operations, maintenance, inspection, record keeping, and training programs are conducted under FAA approved procedures.

The airline industry is subject to legislative actions that may have an impact on operations and costs. In 2024, the U.S. Congress approved a five-year reauthorization for the FAA, which encompasses significant aviation tax and policy-related issues. The law includes a range of policy changes related to enhancing aviation safety, improving and modernizing air traffic control, and strengthening the aviation workforce. Implementation of some items continues into the new Administration, and depending on how they are implemented, could impact Republic’s operations and costs. Additionally, the U.S. Congress may consider legislation related to environmental issues or increases to the U.S. federal corporate income tax rate, which could impact the airline industry.

Consumer Protection Regulation

The DOT also has jurisdiction over certain economic issues affecting air transportation and consumer protection matters, including unfair or deceptive practices and unfair methods of competition by air carriers and ticket agents, airline advertising, denied boarding compensation, ticket refunds, baggage liability, lengthy tarmac delays, contracts of carriage, consumer notices and disclosures, customer service commitments, customer complaints, and transportation of passengers with disabilities. The DOT frequently adopts new consumer protection regulations, and it may adopt new consumer protection regulations in the future, which could impose additional requirements. The DOT also has authority to review certain joint venture agreements, marketing agreements, code-sharing agreements (where an airline places its designator code on a flight operated by another airline), and wet-leasing agreements (where one airline provides aircraft and crew to another airline) between carriers and regulates other economic matters.

Foreign Ownership

Under Federal law and DOT policy, Republic must be owned and controlled by U.S. citizens. The restrictions imposed by Federal law and DOT policy require that Republic’s most senior officer and at least two-thirds of Republic’s Board of Directors and other managing officers be U.S. citizens; that at least 75% of Republic’s voting stock must be owned and controlled, directly and indirectly, by persons or entities who are U.S. citizens; and that Republic be under the actual control of U.S. citizens. In addition, at least 51% of Republic’s total outstanding stock must be owned and controlled by U.S. citizens and no more than 49% of Republic’s stock may be owned or controlled, directly or indirectly, by persons or entities who are not U.S. citizens and are from countries that have entered into “open skies” air transport agreements with the United States which allow unrestricted access between the United States and the applicable foreign country and to points beyond the foreign country on flights serving the foreign country.

Airport Access

Flights at three major domestic airports (Ronald Reagan Washington National Airport (DCA) in Washington, D.C. and New York’s LaGuardia Airport (LGA) and John F. Kennedy International Airport (JFK)) are federally regulated by the DOT and FAA through allocations of landing and take-off authority (i.e. slots, slot exemptions, and operating authorizations (collectively, “Slots”)) or similar regulatory mechanisms, which limit departures and landings at those airports. Each Slot represents the authorization to land at or depart from the particular airport on a particular day during a specified time period.

Republic’s operations at these airports require the allocation of Slots. Republic or the Partner Airlines currently have sufficient Slots to operate Republic’s existing flights, but there is no assurance that Republic will be able to do so in the future because, among other reasons, such Slot allocations are subject to changes in government regulations and policies. Republic has one Slot exemption at DCA which is subject to an expiration date, for which Republic will attempt to seek extension. There is no assurance that the Slot exemption will be extended. Republic’s ability to retain Slots is subject to “use-or-lose” provisions of the governing FAA regulations or orders, and Republic’s ability to expand service at Slot-controlled airports similarly is limited. The DOT and FAA also regulate Slot transactions between airlines. The FAA can grant, and has granted, waivers meeting certain criteria for limited periods that, subject to certain conditions, allow carriers, including us, to maintain existing Slots at Slot-controlled airports while not complying with the use-or-lose provisions of the governing FAA regulations or orders, but future waivers are not assured.

Environmental Regulation

Federal law generally recognizes the proprietary rights of airport operators to implement local noise abatement programs, so long as such programs satisfy various criteria including that they do not interfere unreasonably with interstate or foreign commerce or the national aviation system. Federal law set forth in the Airport Noise and Capacity Act, 49 U.S.C. § 47521, et seq. (“ANCA”) generally limits local laws impacting air space use and management, air traffic control, safety, and the regulation of aircraft noise at its source. The ANCA generally requires FAA approval of local noise restrictions on commercial aircraft. However, certain airports have imposed curfews and noise restrictions that have been

17

Table of Contents

grandfathered under ANCA. In some instances, these restrictions have caused airlines to curtail service or have increased airline operating costs. Such restrictions could limit Republic’s ability to commence or expand its operations at affected airports. While Republic has had sufficient scheduling flexibility to accommodate local noise restrictions imposed to date, Republic’s operations could be adversely affected if locally imposed regulations become more restrictive or widespread.

Republic is subject to various Federal, state, and local laws, and regulations related to the protection of the environment and affecting matters such as aircraft engine emissions and the discharge or disposal of materials and chemicals. The Environmental Protection Agency (“EPA”) regulates aircraft emissions, including air carrier operations, which affect the quality of air in the United States. Republic believes the aircraft in its fleet meet all emission standards issued by the EPA. Republic may become subject to additional taxes or regulations related to greenhouse gas emissions, including reporting requirements, emissions limitations and/or requirements to obtain permits for greenhouse gas emissions.

In addition to other potential regulations, certain U.S. airport authorities are exploring ways to limit de-icing fluid discharges to groundwater, which can result in additional costs to and restrictions on airlines required to participate in the construction of new or modified airports. Additionally, air quality initiatives at the state and local level (including state implementation plans for achieving national ozone standards) could, in the future, result in curtailments in services, increased operating costs, limits on expansion, or further emission reduction requirements. Certain airports and/or state governments either have or are seeking to establish environmental fees and other requirements applicable to carbon emissions, local air quality pollutants, and/or noise.

Security Regulation

The TSA and the U.S. CBP are responsible for certain civil aviation security matters, including passenger and baggage screening at U.S. airports, and international passenger prescreening prior to entry into or departure from the United States. International flights are subject to customs, border, immigration, and similar requirements of equivalent foreign governmental agencies.

Other Regulations

Republic is subject to various other Federal, state, local, and foreign laws and regulations. For example, the U.S. Department of Justice has jurisdiction over certain airline competition matters. Labor relations in the airline industry are generally governed by the RLA. The privacy and security of passenger and employee data is regulated by various U.S. and foreign laws and regulations.

The U.S. government and foreign governments may consider and adopt new laws, regulations, interpretations, and policies regarding a wide variety of matters that could directly or indirectly affect Republic’s results of operations and the price of our common stock. Republic cannot predict what laws, regulations, interpretations, and policies might be considered in the future, nor can Republic judge what impact, if any, the implementation of any of these proposals or changes might have on Republic’s business.

Aircraft Fuel

Republic’s CPAs provide that the Partner Airlines source, procure, and directly pay third party vendors for substantially all fuel used in carrying out passenger service under those agreements. Accordingly, Republic does not recognize fuel expenses or revenues for fuel reimbursement for flying under Republic’s CPAs, and Republic faces very limited exposure to fuel price fluctuations, as these charges are characterized as Partner direct charges.

Insurance

Republic maintains insurance policies that it believes are customary in the industry and in amounts it believes are adequate to protect against material loss and as required by the DOT, lessors, financing parties, and the Partner Airlines under the terms of Republic’s CPAs. The policies principally provide coverage for public liability, passenger liability, baggage and cargo liability, property damage, including coverage for loss or damage to Republic’s flight equipment, and

18

Table of Contents

workers’ compensation insurance. Republic is not insured against cyber risk liability and business interruption. There is no assurance, however, that the amount of insurance Republic carries will be sufficient to protect Republic from material loss. Each of Republic’s CPAs requires Republic to maintain specified types and amounts of insurance.

Community Partnerships

As an Indianapolis-based company with employees who live across the United States, it is an important part of Republic’s culture to support the communities in which Republic works and lives. Republic has several key community partnership initiatives, some of which are:

•Republic Plane Pull: an annual event where teams from areas throughout the Indianapolis and surrounding communities and aviation industry pull one of Republic’s E170/175 aircraft to raise money for several local charities.

•Samaritan’s Feet: a partnership to provide shoes to underprivileged children across the world and engage in Republic’s local communities in Indianapolis and other cities where Republic has significant operations to provide shoes for children in grade schools as well as shelters.

•Food for the Poor: a global partnership that Republic supports financially as well as with mission trips with Republic’s associates to underdeveloped countries to build communities and provide tools and resources to improve access to basic necessities.

•Habitat for Humanity: to support the global need for decent and affordable housing, Republic sponsors the construction of a home with Habitat for Humanity in the hangar each year. The work and partnerships open doors to new possibilities and new realities for community members.

•Wreaths Across America: as a highlight to Republic’s mission to support the military and Remember, Honor, and Teach, each December on National Wreaths Across America Day, Republic’s associates coordinate wreath-laying ceremonies at Arlington National Cemetery and more than 3,700 additional locations in all 50 U.S. states, at sea and abroad.

•Junior Achievement: an extension of Republic’s commitment to workforce development in which Republic provides support and funds to educate children on financial literacy, leadership, and career readiness while also exposing them to opportunities within the aviation industry. Republic also provides various other volunteering opportunities for its employees.

Seasonality

Republic’s results of operations for any interim period are not necessarily indicative of those for the entire year, in part because the airline industry is subject to seasonal fluctuations and changes in general economic conditions. A significant portion of Republic’s CPAs are based on completing flights as scheduled and Republic typically has more scheduled flights during the summer months. Republic generally experiences a significantly higher number of weather cancellations during the winter and active thunderstorm summer months, which negatively impacts Republic’s revenues during these times of year.

Legal Proceedings

Republic is involved in various legal actions in the ordinary course of business. Contingent losses expected to arise because of pending legal matters, which could include expected future settlements, judgments, and legal fees, are recorded when probable and estimable. Republic’s management believes the ultimate outcome of any pending legal matters will not have a material adverse effect on Republic’s consolidated financial statements as a whole.

Additional Information

Republic is incorporated under the laws of the State of Delaware. Republic’s principal executive offices are located at 2 Brickyard Lane, Carmel, Indiana 46032, and Republic’s primary telephone number is (317) 484-6000.
