Item 1. Business

Overview

We are a leisure travel company focused on providing travel and leisure services and products to residents of under-served cities in the United States. We were founded in 1997 and, in conjunction with our initial public offering in 2006, we incorporated in the state of Nevada. Our unique business model provides diversified revenue streams from various travel services and product offerings which distinguish us from other travel companies. We operate a low-cost, low utilization passenger airline marketed primarily to leisure travelers in under-served cities, allowing us to sell air transportation both on a stand-alone basis and bundled with the sale of air-related and third party services and products. In addition, we provide air transportation under fixed fee flight arrangements. Our developed nation-wide route network, pricing philosophy, direct distribution, advertising, and product offerings built around relationships with premier leisure companies, are all intended to appeal to leisure travelers and make it attractive for them to purchase air travel and related services and products from us.

In connection with our leisure travel focus, we have recommenced the construction of our Sunseeker Resort in Southwest Florida. In October 2021, we entered into a credit agreement with affiliates of Castlelake L.P. to finance up to $350 million of the remaining construction cost. With this funding, we expect to open the Resort in early 2023.

Below is a brief description of the travel services and products we provide to our customers:

Scheduled service air transportation.  We provide scheduled air transportation on limited-frequency, nonstop flights predominantly between under-served cities and popular leisure destinations. As of February 14, 2022, our operating fleet consisted of 110 Airbus A320 series aircraft. As of that date, we were selling travel on 615 routes to 132 cities. In this document, references to "Airbus A320 series aircraft" are intended to describe both Airbus A319 and A320 aircraft.

Ancillary air-related products and services.  We provide unbundled air-related services and products in conjunction with air transportation for an additional cost to customers. These optional air-related services and products include baggage fees, advance seat assignments, our own travel protection product, change fees, use of our call center for purchases, priority boarding, a customer convenience fee, food and beverage purchases on board, and other air-related services. The revenue for ancillary air-related products and services is reflected in the Passenger revenue income statement line item, along with scheduled service air transportation revenue and travel point redemptions from the co-branded Allegiant World Mastercard® credit card and our non-card loyalty program.

Third party products and services.  We offer third party travel products such as hotel rooms and ground transportation (rental cars and hotel shuttle products) for sale to our passengers. The marketing component of revenue related to our co-branded credit card is also included for in this category.

Fixed fee contract air transportation.  We provide air transportation through fixed fee agreements and charter service on a year-round and ad-hoc basis.

Other revenue. We have generated revenue from our non-airline activities including our Sunseeker Resort related golf course (temporarily closed since March 2020 and now under renovation), family entertainment centers (no longer operated, having all been closed in 2020), and our management solution to golf courses around the country (business sold in April 2021).

Allegiant 2.0

We continue to sharpen our focus on offerings to meet more of the travel and leisure needs of our customers. We have coined this next stage of our Company strategy as "Allegiant 2.0" which includes the following Company goals:

–maintaining our foundation of providing affordably accessible air travel while refining and strengthening our air travel product;

–expanding our already broad domestic network as we have identified more than 1,400 incremental routes of which approximately 80 percent currently have no non-stop service;

–seeking to offer (subject to government approval) transborder international scheduled service into Mexico through our partnership with Viva Aerobus;

–utilizing our customer data to capture accretive, asset-light direct-to-consumer revenue opportunities;

–transforming our eCommerce strategy to seek to create a frictionless experience for our customers and drive increased air ancillary and third party revenue generation;

–expanding our co-branded credit card program with the launch in August 2021 of our first-ever non-card loyalty program;

–expanding our travel company focus and offerings with the construction of Sunseeker Resort-Charlotte Harbor (construction having recommenced in August 2021).

–refining our marketing investment dollars by entering into dynamic agreements, such as the naming rights agreement with the Raiders of the National Football League for Allegiant Stadium in Las Vegas

Unique Business Model

We have developed a unique business model that primarily focuses on leisure travelers in under-served cities. The business model has evolved as our experienced management team has looked differently at the traditional way business has been conducted in the airline and travel industries. Our focus on the leisure customer allows us to eliminate the significant costs associated with serving a wide variety of customers and to concentrate our product appeal on a customer base which is under-served by traditional airlines. We have consciously developed a business model which distinguishes us from the traditional airline approach:

	Traditional Airline Approach	Allegiant Approach
Customer Base:	Business and leisure	Leisure
Network:	Primarily large and mid-sized markets	Primarily small/medium-sized under-served markets
Competition:	High	Low
Schedule:	Uniform throughout the week	Low frequency/variable capacity
Distribution:	Sell through various intermediaries	Sell only directly to travelers
Fare Strategy:	High base fares/low ancillary revenue	Low base fares/high ancillary revenue

By separating base airfare from our air-related services and products such as baggage fees, advance seat assignments, travel protection, change fees, priority boarding, and food and beverage purchases, we are able to lower our airfares and target leisure travelers who are more concerned with price and the ability to customize their experience with us by only purchasing the additional conveniences they value. This strategy allows us to generate additional passenger revenues from our customers' decisions to purchase these ancillary products.

We have established a broad route network with a national footprint, providing service on 593 routes between 98 origination cities and 33 leisure destinations, and serving 43 states as of February 14, 2022. As of this same date, we were selling 615 routes. In most of these cities, we provide service to more than one of our leisure destinations which are offered either on a year-round or seasonal basis. Our vast network footprint, coupled with our low frequency scheduling, provides us with a diversified, resilient network. We operate to more cities than any non-legacy carrier, protecting us against overexposure to any one geographic location. Our 23 bases (including Flint and Appleton starting in February and March 2022, respectively) provide us the flexibility to redeploy capacity to best match demand trends around the country.

6

The geographic diversity of our route network protects us from regional variations in the economy and helps insulate us from competitive actions, as it would be difficult for a competitor to materially impact our business by targeting one city or region. Our widespread route network also contributes to the continued growth of our customer base. The below map illustrates our route network as of February 14, 2022, including service announcements as of that date. The orange dots represent leisure destinations and the blue dots represent origination cities.

We have identified up to 1,400 additional domestic routes which we could target in the future to further expand our network.

7

In developing a unique business model, our ancillary offerings (ancillary air-related items included in passenger revenue as well as the sale of third party products and services) have been a significant source of our revenue growth. We have increased revenue related to these ancillary items from $5.87 per passenger in 2004 to $64.73 per passenger in 2021. We own and manage our own eCommerce platform, which gives us the ability to modify our system to enhance third party product offerings based on specific needs, without being dependent on non-customized product upgrades from outside suppliers. We believe the control of our automation systems has allowed us to be innovators in the industry by providing our customers with a variety of different travel services and products, and allowing us to seek to increase revenues through testing of alternative revenue management approaches.

We believe the following strengths from our unique business model allow us to maintain a competitive advantage in the markets we serve:

Focus on leisure traffic from under-served cities

We believe small and medium-sized cities represent a large, under-served market, especially for leisure travel. Prior to the initiation of our service, leisure travelers from these markets had limited desirable options to reach leisure destinations because existing carriers are generally focused on connecting business customers through their hub-and-spoke networks.

We believe our low fare, nonstop service, along with our leisure company relationships, make it attractive for leisure travelers to purchase airfare and travel-related products from us. The size of the markets we serve, and our focus on the leisure customer, allow us to adequately serve these markets with less frequency, and to vary our air transportation capacity to match seasonal and day-of-the-week demand patterns.

By focusing primarily on under-served cities and routes, we believe we avoid the intense competition in high traffic domestic air corridors. In most of our markets, travelers previously faced high airfares and cumbersome connections, or long drives, to major airports in order to reach our leisure destinations. Based on published data from the U.S. Department of Transportation (“DOT”), we believe the initiation of our service stimulates demand, as we have typically seen a substantial increase in traffic subsequent to new service beginning. Our market strategy is neither hostile to legacy carriers, whose historical focus has been connecting small cities to business markets with regional jets, nor to traditional low cost or ultra-low cost carriers generally focused on larger markets. Additionally, major carriers have reduced service to medium-sized cities which we believe they no longer consider to be core hubs.

Capacity management

We actively manage our seat capacity to match leisure demand patterns. Our ability to quickly adjust capacity helps us maintain profitability in the dynamic travel industry. Because of highly variable cost structure, our flexibility allows us to uniquely match capacity with the demand environment.

Our core business model manages seat capacity by increased utilization of our aircraft during periods of high leisure demand and decreased utilization in low leisure demand periods. By way of illustration, in 2021, during our peak demand period in July, we averaged 9.4 system block hours per aircraft per day while in September, our lowest month for demand, we averaged only 4.9 system block hours per aircraft per day.

Our management of seat capacity also includes changes in weekly frequency of certain markets based on identified peak and off-peak travel demand throughout the year. Unlike other carriers which provide a fairly consistent number of flights every day of the week, we manage our capacity with a goal of being profitable on each route. We do this by flying only on days with sufficient market demand. In 2021, we were able to profitably fly a disproportionately low 13.1 percent of our scheduled ASMs on off-peak days (Tuesdays and Wednesdays).

To effectively hedge against fuel cost increases during periods of high fuel cost, we consider reducing capacity which allows us to raise average fares due to supply-demand dynamics and thereby offset the fuel cost increase.

Our strong revenue production from ancillary items, coupled with our ability to rapidly deploy or contract capacity, has allowed us to consistently operate profitably and produce industry leading margins in challenging macro environments, including periods of high fuel prices, economic recession and a pandemic.

Low cost structure

We believe a low cost structure is essential to competitive success in the airline industry, particularly as a solely leisure focused carrier. Our ASMs increased 8.1 percent in 2021 compared to 2019. Our adjusted operating expense per available seat mile ("CASM") was 9.12¢ in 2021 versus 9.13¢ in 2019. Excluding the cost of fuel, our adjusted operating CASM was 6.60¢ in 2021 versus 6.48¢ in 2019.

We continue to focus on maintaining low operating costs through the following tactics and strategies:

8

Low aircraft ownership costs. We achieve low aircraft ownership costs by primarily owning our aircraft. As of February 14, 2022, we own or finance lease all but 15 of the aircraft in our operating fleet. In addition, we believe that we properly balance lower aircraft acquisition costs and operating costs to minimize our total costs.

We primarily purchase used aircraft with meaningful remaining useful lives, at reduced prices. As of February 14, 2022, our operating fleet consists of 110 Airbus A320 series aircraft, of which 97 were acquired used.

In December 2021, we signed an agreement with The Boeing Company to purchase 50 newly manufactured 737MAX aircraft scheduled to be delivered in 2023 to 2025 with options to purchase an additional 50 737’s. We believe this new aircraft purchase is complimentary with our low cost strategy. Our intent to retain ownership of the aircraft, coupled with the longer useful life for depreciation purposes should result in similar ownership expense when compared with a used aircraft in our fleet. In addition, the expected fuel savings of up to 20 percent, improved operational reliability, and other savings expected from the use of these new aircraft should aid in improving our overall low cost structure.

Low distribution costs. Our nontraditional marketing approach results in very low distribution costs. We do not sell our product through outside sales channels, thus avoiding the fees charged by travel websites (Expedia, Orbitz or Travelocity) and traditional global distribution systems (“GDS”) (Sabre or Worldspan). Our customers can only purchase travel at our airport ticket counters or, for a fee, on our website or through our telephone reservation center. The purchase of travel through our website is the least expensive form of distribution for us and accounted for 94.7 percent of our scheduled service revenue during 2021.

Data driven. We are continuing to focus on capturing data to identify trends and patterns in an effort to gain efficiencies and decrease costs. For example, we utilize predictive maintenance to identify necessary aircraft maintenance before a problem arises, thereby avoiding unscheduled maintenance events which are costly and disruptive to our schedule. In addition, our direct to consumer distribution method results in significant sales and marketing cost savings.

Highly productive workforce. Our high level of employee productivity is due to our cost-driven scheduling, fewer unproductive labor work rules, and the effective use of automation and part-time employees. In an effort to control costs, we outsource major maintenance, stations and other functions to reliable third party service providers.

Simple product. We believe offering a simple product is critical to achieving low operating costs. As such, we sell only nonstop flights; we do not currently code-share or interline with other carriers; we have a single class cabin; we do not provide any free catered items - everything on board is for sale; we do not provide cargo or mail services; and we do not offer other perks such as airport lounges.

Under-served market airports. Our business model focuses on residents of under-served cities in the United States. Typically, the airports in these cities have lower operating costs than airports in larger cities. These lower costs are driven by less expensive passenger facilities, landing, and ground service charges. In addition to inexpensive airport costs, many of our airports provide marketing support.

Cost-driven schedule. We aim to build our scheduled service so that substantially all of our crews and aircraft return to base each night. This allows us to maximize crew efficiency, and more cost-effectively manage maintenance, spare aircraft and spare parts. Additionally, this structure allows us to add or subtract markets served by a base without incremental costs. We believe leisure travelers are generally less concerned about departure and arrival times than business travelers, so we are able to schedule flights at times that enable us to reduce costs while remaining desirable to our leisure customers.

Ancillary product offerings

We believe many leisure travelers are concerned primarily with purchasing air travel at the least expensive price. As such, we offer the unbundling of the air transportation product by charging fees for services many U.S. airlines have historically only bundled in their base fare. This pricing structure allows us to target travelers who are most concerned with low fare travel while also allowing travelers to customize their experience with us by purchasing only the additional conveniences they value. For example, we do not offer complimentary advance seat assignments; however, customers who value this product can purchase advance seat assignments for a small incremental cost. In addition, snacks and beverages are sold individually on the aircraft, allowing passengers to purchase only items they value. Our direct to consumer distribution method enables a variety of added revenue opportunities with direct “one-stop” shopping solutions and managed product offerings.

We offer various bundled ancillary products whereby customers can elect to purchase multiple ancillary products at a discount.

Revenue from ancillary items will continue to be a key component in our total average fare as we believe leisure travelers are less sensitive to ancillary fees than the base fare.

Our third party product offerings give our customers the opportunity to purchase hotel rooms, rental cars and airport shuttle service. Our third party offerings are available to customers based on our agreements with various travel and leisure companies. For example, we have partnered exclusively with Enterprise Holdings Inc. for the sale of rental cars packaged with air travel, which generated approximately 58 percent of our third party products revenue in 2021. The pricing of each product and our margin can be adjusted based on customer demand because our customers purchase travel directly through our booking engine.

Financial position

As of December 31, 2021, we had $1.19 billion of unrestricted cash, cash equivalents and investment securities, and total debt and finance lease obligations (net of related costs) of $1.74 billion. We had net debt (total debt and finance lease obligations less cash, cash equivalents and investment securities) of $557.5 million as of December 31, 2021, a 42.8 percent decrease from the $973.8 million balance as of December 31, 2020. Based on our assumptions about the future impact of COVID-19 on travel demand, which could be materially different due to the inherent uncertainties of the current operating environment, we expect to meet our cash obligations as well as remain in compliance with the debt covenants in our existing financing agreements for the next 12 months given our current level of unrestricted cash and short-term investments, our anticipated access to liquidity, and projected cash flows from operations.

Our financial position and discipline regarding use of capital allow us to have greater financial flexibility to grow our business and to efficiently and effectively adapt to changing economic conditions.

10

Routes and schedules

Our current scheduled air service (including seasonal service) predominantly consists of limited frequency, nonstop flights into leisure destinations from under-served cities across the continental United States. The scheduled service routes we are selling as of February 14, 2022 are summarized below (includes 593 routes we are currently serving, and 22 new announced routes on which will begin service in 2022):

Routes to Orlando	69
Routes to Las Vegas	63
Routes to Tampa/St. Petersburg	59
Routes to Punta Gorda	55
Routes to Phoenix	54
Routes to Destin	37
Routes to Los Angeles	42
Other routes	236
Total routes	615

The number of routes served varies from time to time as some routes are offered seasonally or on a temporary basis.

Marketing and Distribution

Core to Allegiant’s business model is our direct-to-consumer distribution. In lieu of the GDS distribution points used by most airlines, allegiant.com is our primary distribution method. This low-cost strategy results in significant cost savings by avoiding fees associated with GDS. It also enables a variety of added revenue opportunities with direct “one-stop” shopping solutions and managed product offerings.

Automation is key to this strategy as we continue to enhance our capabilities. Our redesigned website and mobile app streamline the booking process and strengthen our ability to sell air ancillary and third party products. Additionally, we expect other automation enhancements will create additional revenue opportunities by allowing us to capitalize on customer loyalty with additional product offerings.

Our direct-to-customer distribution method also enables us to gather valuable customer data. In addition to helping us better understand our customers, we utilize data like customer email addresses to market our products and services in a cost-effective way. Database marketing opportunities span the full customer journey including the time of travel purchase, between purchase and travel, and after travel is complete. To this end, we entered into a multi-year collaboration with Amazon Web Services to strengthen customer engagement through increased personalization across our digital channels, while affording a more elastic, reliable IT infrastructure with significant development advantages for marketing as well as for other business units across the company.

Beyond allegiant.com, we market our products and services through a combination of digital and traditional advertising including radio and television. Whether introducing new service to a community or promoting existing routes, our advertising is often supported by airport authorities and destination marketing organizations. We continue to see benefit from these cooperative marketing campaigns, as well as from high-profile sponsorships like Allegiant Stadium. Underpinning our advertising efforts, high-profile sponsorships add credibility to our brand, drive new customer acquisition and enhance our national profile.

Our co-branded Allegiant World Mastercard® incentivizes customers who fly more often to maximize their benefits with members-only promotions and travel perks like complimentary priority boarding. Cardholders are among our most engaged customers and book air ancillary and third party products at a higher rate than other customers. Our non-card loyalty program, Allways Rewards™, launched in August 2021, allows us to develop and maintain direct, long-term relationships with our customers. Similar to our cardholder program, we provide greater value to our Allways members through personalized promotions and targeted communications which we expect will result in customer loyalty and increased revenues over time.

Competition

The airline industry is highly competitive. Passenger demand and fare levels have historically been influenced by, among other things, the general state of the economy, international events, fuel prices, industry capacity, and pricing actions taken by other airlines. The principal competitive factors in the airline industry are price, schedule, customer service, routes served, types of aircraft, safety record and reputation, code-sharing relationships, and frequent flyer or loyalty programs.

Our competitors include legacy airlines, low cost carriers ("LCCs"), ultra-low cost carriers ("ULCC"), regional airlines, new entrant airlines, and other forms of transportation to a much lesser extent. Many of the airlines are larger, have significantly greater financial resources, are better known, and have more established reputations than us. In a limited number of cases, following our entry into a market, competitors have chosen to add service, reduce their fares, or both. Competitors may also choose to enter after we have developed a market.

11

We believe our under-served city strategy and less than daily service has reduced the intensity of competition we might otherwise face. As of February 14, 2022, we are the only mainline domestic scheduled carrier operating out of the Orlando Sanford International Airport and at 11 other airports in our network. We and Sun Country Airlines are the only mainline domestic scheduled carriers serving Phoenix Mesa Gateway Airport, Punta Gorda Airport, and St. Petersburg-Clearwater Airport. Although no other mainline domestic scheduled carriers operate in these airports, most U.S. airlines serve the major airport for Orlando, Phoenix, Fort Myers, and Tampa. In addition, many U.S. airlines serve our other leisure destinations. As a result, there is potential for increased competition on our routes.

As of February 3, 2022, we face mainline competition on approximately 27 percent of our operating and announced routes. We overlap with Southwest Airlines on 119 routes, Frontier Airlines on 60 routes, Spirit Airlines on 34 routes, American Airlines on 19 routes, Delta Airlines on 16 routes, Breeze Airways on 12 routes, United Airlines on ten routes, JetBlue Airlines on nine routes, Sun Country Airlines on seven routes and Alaska Airlines on two routes. In many cases, we face competition from more than one other airline on the same route, resulting in a total of 167 competitive routes as of that date. We may also experience additional competition based on recent route announcements of other airlines.

Indirectly, we compete with various carriers that provide nonstop service to our leisure destinations from airports near our cities. We also face indirect competition from legacy carriers offering hub-and-spoke connecting flights to our markets, although these fares tend to be substantially higher, with much longer elapsed travel times. Several airlines also offer competitive one-stop service from the cities we serve.

In our fixed fee operations, we compete with other scheduled airlines in addition to independent passenger charter airlines. We also compete with aircraft owned or controlled by large tour companies. The basis of competition in the fixed fee market is cost, equipment capabilities, service, reputation, and schedule flexibility.

Environmental, Social and Governance (ESG)

We recognize our responsibility to reduce environmental impact from our operations. As an integrated travel company with an expanding airline business, we believe that solidifying our commitment to ESG efforts is a natural integration into our long-term corporate strategy and will enable us to better serve our stakeholders. In 2022, we entered a 3-year partnership with Schneider Electric to develop a comprehensive ESG program. Through this partnership, we will:

–Identify and prioritize relevant ESG topics through a materiality assessment

–Establish ESG goals and environmental goal achievement plans

–Develop inaugural ESG report referencing the Global Reporting Initiative (GRI) and Sustainability Accounting Standards Board (SASB) frameworks

–Provide ongoing carbon emissions reporting of Scope 1, 2 and 3 greenhouse gas (GHG) emissions using Schneider Electric’s EcoStruxureTM Resource Advisor

–Support the communications efforts around our ESG program

In addition, we made recent investments in several ESG areas that will enable us to build a more resilient business, drive greater efficiencies and give back to our communities. These include the following:

–Environmental: Agreed to purchase 50 Boeing 737 aircraft, which burn up to 20% less fuel than our existing Airbus A320 fleet.

–Social: Sponsored Girls in Aviation Day in partnership with Women in Aviation Las Vegas and resumed in-kind travel for Make-a-Wish kids and their families in late 2021. Donated portions of proceeds from pink in-flight refreshment sales in October to the National Breast Cancer Foundation.

–Governance: Sought greater boardroom diversity and, as a result, achieved a board membership that is 25 percent female and 12.5 percent ethnically diverse. Selected Amazon Cloud Services (AWS) as our preferred cloud provider to ensure greater security and reliability in its IT infrastructure.

Environment

The aviation industry accounts for roughly two percent of global greenhouse gas emissions, almost all of which is attributable to aircraft fuel. In 2013, we began the process of transitioning our fleet from a mixture of MD-80 aircraft and Boeing 757 aircraft to an all-Airbus fleet with the transition concluding in November of 2018. Throughout this transition period and continuing through 2021, we saw significant improvement in fuel efficiency. During 2021, we consumed 205 million gallons of fuel averaging 85.4 ASMs per gallon of fuel, a 36 percent improvement when compared to 2012. We recently announced an agreement with Boeing and CFM International to purchase 50 Boeing 737 aircraft powered by LEAP 1-B engines, with deliveries beginning mid-2023. This aircraft is expected to burn up to 20 percent less fuel than our existing fleet, while offering increased seating capacity.

As of December 31, 2021, the composition of our fleet included a mix of A319 and A320 aircraft with seat configurations ranging from 156 to 186 seats, some of which are fitted with fuel-efficient Sharklets. As we grow the fleet over the next several years, the preference will be to continue adding 186-seat Airbus aircraft in addition to our Boeing 737 order. We expect to continue to see modest improvements in fuel efficiency due to further upgauging.

Despite the significant fuel efficiencies gained over the past decade, we recognize we have a responsibility to do more. We have an internal Fuel Steering Committee that meets monthly to discuss various alternatives to conserve fuel. In conjunction with the

12

focused efforts and contributions of our pilots, dispatchers, and stations personnel, we have implemented several fuel conservation practices, which include the following:

• Single engine taxi in and out, as time permits

• Constant descent angle approach, as permitted by air traffic

• Flaps 3 for landing, an Airbus green procedure creating less drag during the landing process, conditions permitting

• Idle thrust reverse for landing, conditions permitting

• Auxiliary power unit fuel optimization

• Route optimization

• Data collection by aircraft to identify performance deterioration and rectify where necessary

• Trial of several electric ground handling equipment

In addition to the above initiatives, the Fuel Steering Committee is currently researching sustainable aviation fuel to see if this could be a viable option on some of our routes.

Unlike many air carriers focused on business travel, our strategy is to provide access to affordable travel for leisure travelers who highly value their vacations and are likely to take vacations in any economic environment. We are a low utilization air carrier focusing on leisure travel, thus we seek to closely match our available capacity with demand trends in providing only non-stop service from under-served cities to leisure destinations. By way of example, in 2021 during our peak demand period in July, we averaged 9.4 system block hours per aircraft per day while in September, we averaged only 4.9 system block hours per aircraft per day when leisure demand is seasonally lower. This practice of significantly reduced flying during the off-peak periods leads to consistently high load factors, and further enhances fuel efficiency. During 2021, we consumed roughly 16.6 gallons of fuel per thousand revenue passenger miles compared with an industry average of 18.9 gallons per thousand revenue passenger miles, or 12 percent more efficient on a revenue passenger mile basis. We offer all non-stop flights, directly from 132 cities as of February 14, 2022, providing service in many markets abandoned or under-served by larger carriers. If not for Allegiant, many of the customers we serve would not have access to direct flights by virtue of either geography or price point. Prior to our initiation of service on these routes, many of these passengers either traveled by car, which is significantly less fuel efficient than air travel, or traveled by car to larger airports to fly, where higher cost connecting flights were the only option. As fuel consumption is greatest during take-off, the ability to travel to the destination with a single take-off, as opposed to at least two take-offs on connecting flights, is more fuel efficient.

Aircraft Fuel

The cost of fuel is volatile, as it is subject to many economic and geopolitical factors we can neither control nor predict. Significant increases in fuel costs could materially affect our operating results and profitability. We have not used financial derivative products to hedge our exposure to fuel price volatility in over 15 years, nor do we have any plans to do so in the future. Our largely variable cost structure allows us to adjust to capacity accordingly based on the fuel environment.

Data Security

We continue to invest heavily in cyber-security, cyber-risk, vendor-risk and privacy initiatives. We employ experienced staff dedicated to cyber-security and cyber-risk analysis, process and technology. We continue to evaluate and proactively implement new preventive and detective processes and technologies including forward-looking threat intelligence and data-centric security measures.

One of our current and ongoing data security initiatives is the migration of critical business applications into the cloud infrastructure, which will allow us to take advantage of analytics and automation functionality. These improvements also provide further opportunities to increase business intelligence and flexibility, improve business continuity and mitigate disaster scenarios. We intend to continue investing resources in cyber security to protect our data and our customers' privacy.

Employees

As of December 31, 2021, we employed 4,458 full-time equivalent employees, which consisted of 4,183 full-time and 550 part-time employees. Full-time equivalent employees consisted of approximately 1,100 pilots, 1,500 flight attendants, 350 airport operations personnel, 550 maintenance personnel, 200 reservation agents, 40 flight dispatchers, and 750 management and other personnel.

Our relations with labor organizations representing our airline employee groups are governed by the Railway Labor Act ("RLA"). Under this act, if direct negotiations do not result in an agreement, either party may request the National Mediation Board ("NMB") to appoint a federal mediator. If no agreement is reached in these mediated discussions, the NMB may offer binding arbitration to the parties. If either party rejects binding arbitration, a “cooling off” period begins. At the end of this “cooling-off” period, the parties may engage in self-help, which among other events, could result in a strike from employees or for us to hire new employees to replace any striking workers.

The collective bargaining agreement with our pilots is currently amendable and the parties have begun to discuss the terms of a new labor agreement for this work group.

13

The collective bargaining agreements for our flight attendants, dispatchers and maintenance technicians last for a contractual term of five years each, expiring in 2022, 2024 and 2026 respectively.

If we are unable to reach a labor agreement with any employee group, they may seek to institute work interruptions or stoppages following unsuccessful Federal mediation and other work stoppage protections provided for under the RLA. We have not previously experienced any work interruptions or stoppages from our non-unionized or unionized employee groups.

Human Capital

As part of our human capital resource objectives, we seek to recruit, retain, and develop our existing and future workforce. We strive to build and maintain a diverse environment that people want to join, and where team members want to stay to build their careers. Our total rewards philosophies support these objectives. Above all else, safety is our number one core value, along with achievement, flexibility, innovation, bias for action, teamwork, transparency and accountability, and outcome-based values that define our human capital mission.

We have long supported Diversity, Equity and Inclusion and operate a Diversity & Inclusivity Council made up of company leadership, and facilitate multiple company-wide network groups to inspire a more inclusive culture while giving a dedicated focus to our recruiting processes to continue driving diverse hiring.

Our total rewards philosophy is based around building a culture of high performance. We utilize competitive base salaries, discretionary performance-based bonuses, profit sharing and equity as attraction and retention tools for our team members.

As of December 31, 2021, we had approximately 4,700 team members (including both full-time and part-time employees), of whom approximately 72 percent are in front line positions such as flight crew, mechanics or airport personnel.

The safety and well-being of our team members is a top priority, and we believe each and every team member plays an essential role in creating a safe and healthy workplace. Our health and safety policies and practices are intended to protect not only our team members but also our customers in all things we do, and include our vigorous COVID-19 response. Additionally, our human capital focus has been externally recognized through Allegiant’s placement on Newsweek's Most Loved Workplaces 2021 and Forbes' America's 500 Best Employers in Diversity 2021.

Community Involvement

Allegiant has worked with the Make-A-Wish® Foundation since 2012 by flying "wish kids" and their families to their desired destinations, at no cost, and donating a portion of proceeds from our in-flight Wingz Kids Snack Pack to the organization. Beginning in 2020, the flights were suspended due to COVID-19 and have resumed as of December 31, 2021. Additionally, we donate the use of 7,500 square feet of office space at our headquarters campus to the Southern Nevada chapter of Make-A-Wish, providing a home for the nonprofit organization's administrative office at no cost. The site also serves as the host location for volunteer training, meetings and a place of support for families of children receiving wishes. Allegiant is considered a Wish Champion by Make-A-Wish America, recognizing more than $1 million in annual contributions.

We have also been a national partner with The Arc, a nonprofit organization dedicated to advocacy on behalf of people with intellectual and developmental disabilities. Allegiant partners with the organization to offer “Wings for All” educational programs in communities we serve, helping make travel accessible for individuals with autism and other developmental disabilities.

Allegiant supports Science, Technology, Engineering and Mathematics ("STEM") education programs that provide access to careers in aeronautical sciences in under-served communities. We have partnered with local high schools and with Embry-Riddle Aeronautical University to offer Allegiant Careers in Aviation Scholarships, assisting students pursuing careers in the aviation industry.

We also partner with the American Red Cross, supporting disaster preparedness, relief and recovery efforts in communities we serve. In this effort, we have provided no-cost supply flights and volunteer transport to support Red Cross hurricane recovery efforts in Florida and Puerto Rico. In addition, Allegiant has sponsored community blood drives and preparedness efforts such as home smoke detector installation in under-served neighborhoods.

During the COVID-19 pandemic and periodically, we provide additional support in our home community of Las Vegas, donating surplus in-flight food and beverage items such as juices, sodas and snacks to a local community food bank for distribution to families in need. We also provide flight vouchers on an annual basis to hundreds of local elementary and high school teachers as part of The Smith Center for the Performing Arts’ Heart of Education Awards program. Our goal is to help ensure that educators who continue to work tirelessly despite the incredible challenges of the pandemic have an opportunity to take a well-deserved vacation in the future.

Aircraft Maintenance

We have a Federal Aviation Administration ("FAA") approved maintenance program, which is administered by our maintenance department headquartered in Las Vegas. Technicians employed by us have appropriate experience and hold required licenses issued by the FAA. We provide them with comprehensive training and maintain our aircraft in accordance with FAA regulations. The maintenance performed on our aircraft can be divided into three general categories: line maintenance, major maintenance,

14

and component and engine overhaul and repair. Line maintenance is generally performed by our personnel in certain cities of our network and by contractors elsewhere. We contract with FAA-approved outside organizations to provide major maintenance and component and engine overhaul and repair. We have chosen not to invest in facilities or equipment to perform our own major maintenance, engine overhaul or component work. Our management supervises all maintenance functions performed by our personnel and contractors employed by us, and by outside organizations. In addition to the maintenance contractors we presently utilize, we believe there are sufficient qualified alternative providers of maintenance services that we can use to satisfy our ongoing maintenance needs.

Viva Aerobus Alliance

In December 2021, we announced plans for a fully-integrated commercial alliance agreement with Viva Aerobus, designed to expand options for nonstop leisure air travel between our markets in the United States and Mexico. We and Viva Aerobus have submitted a joint application to the DOT requesting approval of and antitrust immunity for the alliance. We believe this alliance is consistent with the DOT's goal of providing maximum benefits to the public, as the alliance is expected to increase competition, reduce transborder fares and provide increased nonstop service for our consumers traveling between the US and Mexico.

The alliance is anticipated to add new transborder routes and nonstop competition where currently only connecting service is available. More than 250 new potential nonstop route opportunities have been identified as part of the DOT application, though specific routes targeted for service wilI be announced at a later date, following the application's approval.

We and Viva Aerobus currently expect to offer flights under the alliance beginning in the first quarter of 2023, pending governmental approval of the applications.

In addition, we have made an equity investment of $50.0 million in Viva Aerobus, and our Chairman Maurice J. Gallagher, Jr. is expected to join the Viva Aerobus board of directors. The transactions are also subject to clearance by the Mexican Federal Economic Competition Commission.

Non-Airline Initiatives

Sunseeker Resort

We are developing a resort in Southwest Florida (the "Resort" or "Sunseeker Resort"). When completed, the Resort will feature approximately 500 hotel rooms, more than 180 extended-stay suites, 55,000 square feet of meeting and conference space, 19 restaurants and bars, a rooftop pool and a ground level pool, a fitness center and spa and retail outlets along a harbor walk. We also own a golf course which is a short drive from the Resort site and is considered to be an additional Resort amenity.

Construction on the Resort began in the first quarter of 2019 and was suspended in March 2020 so that we could conserve liquidity during the pandemic. The golf course closed for renovation just before the pandemic and the renovation was suspended to conserve liquidity during the pandemic. We recommenced construction on the Resort in August 2021 and commenced the golf course renovation in November 2021. In October 2021, we entered into a credit agreement with affiliates of Castlelake L.P. to finance up to $350 million of the remaining construction cost. With this funding, we expect to open the Resort in early 2023. We expect that the renovated golf course will open simultaneously with the Resort.

Teesnap

We previously operated Teesnap as a golf course management solution. In April 2021, we closed on a transaction to sell 85 percent of Teesnap, retaining a 15 percent ownership in the business.

Family Entertainment Centers

We previously opened two family entertainment centers ("FECs") in 2019 in Clearfield, UT and Warren, MI. We closed both FECs as a result of the pandemic and we have now disposed of those assets. We will no longer pursue this business line.

Other travel and leisure initiatives

Consistent with our travel and leisure company focus, we may pursue other travel and leisure initiatives from time to time in the future.

Insurance

We maintain insurance policies we believe are of types customary in the airline industry and as required by the DOT, and are in amounts we believe to be adequate to protect us against material loss. The policies principally provide coverage for public liability, war-risk, passenger liability, baggage and cargo liability, property damage, including coverages for loss or damage to our flight equipment and directors and officers, workers’ compensation. We also maintain what we believe to be customary insurance on Sunseeker Resort and as required by the terms of our construction loan. There is no assurance, however, that the amount of insurance we carry will be sufficient to protect us from material loss in all cases. Available commercial insurance in the future could be more expensive, could have material differences in coverage than is currently provided, and may not be adequate to protect us from risk of loss.

Government Regulation

15

We are subject to federal, state and local laws affecting the airline industry and to extensive regulation by the DOT, the FAA, and other governmental agencies.

DOT. The DOT primarily regulates economic issues affecting air transportation such as certification and fitness of carriers, consumer protection, competitive practices, insurance requirements, and statistical reporting. The DOT also regulates requirements for accommodation of passengers with disabilities, including those using service animals. The DOT monitors the continuing fitness of carriers and has the authority to promulgate regulations and to investigate (including by on-site inspections) and institute proceedings to enforce its regulations and related federal statutes, and may assess civil penalties, suspend or revoke operating authority, and seek criminal sanctions. The DOT also has authority to restrict or prohibit a carrier’s cessation of service to certain communities if such cessation would leave the community without scheduled airline service.

In addition, the DOT has authority to approve alliance or partnership agreements under which two or more air carriers collaborate and to grant immunity from U.S. antitrust laws for the provision of such collaboration. On December 1, 2021, we (i.e., our airline subsidiary) and Aeroenlaces Nacionales, S.A. de C.V. doing business as Viva Aerobus (“Viva”), a Mexican airline, submitted to DOT a joint application requesting approval of and antitrust immunity for a comprehensive alliance agreement applicable to all routes we and/or Viva may operate between points in the United States and points in Mexico. The joint application explains how the proposed Allegiant-Viva alliance is expected to benefit the traveling public by bringing significant new competition and service options, including lower fares, additional capacity on existing routes, and increased overall transborder capacity in the form of nonstop flights on routes now served only via connecting service. We and Viva have asked DOT to provide final approval of the alliance agreement and to issue antitrust immunity by July 31, 2022, to help facilitate inauguration of service under the agreement in the first quarter of 2023. Some previous applications involving other carriers have taken DOT far longer to process, and there is no assurance our proposed time frame will be achieved. Nor is there assurance DOT will ultimately approve the agreement and grant antitrust immunity.

We hold DOT certificates of public convenience and necessity authorizing us to engage in scheduled air transportation of passengers, property and mail within the United States, its territories and possessions, and between the United States and all countries that maintain a liberal aviation trade relationship with the United States (known as “open skies” countries). We also hold DOT authority to engage in scheduled air transportation of passengers, property and mail between the United States and Mexico. We also hold DOT authority to engage in charter air transportation of passengers, property, and mail on a domestic and international basis.

FAA. The FAA primarily regulates flight operations and safety, including matters such as airworthiness and maintenance requirements for aircraft, pilot, mechanic, dispatcher and flight attendant training and certification, flight and duty time limitations, and air traffic control. The FAA requires each commercial airline to obtain and hold an FAA air carrier certificate. This certificate, in combination with operation specifications issued to the airline by the FAA, authorizes the airline to operate at specific airports using aircraft certificated by the FAA. We have and maintain in effect FAA certificates of airworthiness for all of our aircraft, and we hold the necessary FAA authority to fly to all of the cities we currently serve. Like all U.S. certificated carriers, our provision of scheduled service to certain destinations may require specific governmental authorization. The FAA has the authority to investigate all matters within its purview, to modify, suspend or revoke our authority to provide air transportation, to approve or disapprove the addition of aircraft to our operation specifications, and to modify, suspend or revoke FAA licenses issued to individual personnel, for failure to comply with FAA regulations. The FAA can assess civil penalties for such failures and institute proceedings for the collection of monetary fines after notice and hearing. The FAA also has authority to seek criminal sanctions. The FAA can suspend or revoke our authority to provide air transportation on an emergency basis, without notice and hearing, if, in the FAA’s judgment, safety requires such action. A legal right to an independent, expedited review of such FAA action exists. Emergency suspensions or revocations have been upheld with few exceptions. The FAA monitors our compliance with maintenance, flight operations and safety regulations on an ongoing basis, maintains a continuous working relationship with our operations and maintenance management personnel, and performs pre-scheduled inspections as well as frequent spot inspections of our aircraft, employees and records.

The FAA also has the authority to promulgate rules and regulations and issue maintenance directives and other mandatory orders relating to, among other things, inspection, repair and modification of aircraft and engines, safety management systems, aircraft equipment requirements, noise abatement, mandatory removal and replacement of aircraft parts and components, mandatory retirement of aircraft, operational requirements and procedures, and employee drug and alcohol testing. Such rules, regulations and directives are normally issued after an opportunity for public comment; however, they may be issued without advance notice or opportunity for comment if, in the FAA’s judgment, safety requires such action. We believe we are operating in compliance with applicable DOT and FAA regulations, interpretations and policies and we hold all necessary operating and airworthiness authorizations, certificates and licenses.

The FAA periodically conducts extensive or targeted audits of our operations. We have satisfactorily responded to any and all findings on all Certificate Holder Evaluation Process and other inspections conducted.

Security. Within the United States, civil aviation security functions, including review and approval of the content and implementation of air carriers’ security programs, passenger and baggage screening, cargo security measures, airport security, assessment and distribution of intelligence, threat response, and security research and development are the responsibility of the Transportation Security Administration (“TSA”) of the Department of Homeland Security. The TSA has enforcement powers similar to the DOT’s and FAA’s described above. It also has the authority to issue regulations, including in cases of emergency, the authority to do so without advance notice, including issuance of a grounding order as occurred on September 11, 2001. In addition, TSA has authority over face mask requirements applicable to individuals across all U.S. public transportation networks,

16

including at airports and onboard commercial aircraft. In August 2021 TSA extended the face mask requirement through March 18, 2022; a further extension is possible.

Aviation Taxes and Fees. The authority of the federal government to collect most types of aviation taxes, which are used, in part, to finance the nation’s airport and air traffic control systems, and the authority of the FAA to expend those funds must be periodically reauthorized by the U.S. Congress. On October 5, 2018, the FAA Reauthorization Act of 2018 was signed into law extending certain commercial aviation taxes (known generally as Federal Excise Taxes or "FET") through September 30, 2023. All carriers are required to collect these taxes from passengers and pass them through to the federal government. In addition to FET, there are federal fees related to services provided by the TSA, and, in the case of international flights, U.S. Customs and Border Protection ("CBP"), U.S. Citizenship and Immigration Services (“CIS”), and the U.S. Department of Agriculture's Animal and Plant Health Inspection Service ("APHIS"). There are also FAA-approved Passenger Facility Charges ("PFCs") imposed by most of the airports we serve. Like FET, air carriers are required to collect these fees from passengers and pass them through to the respective federal agency or airport authority. These fees do not need to be reauthorized, although their amounts may be revised periodically.

In 2022 or thereafter, Congress may consider legislation that could increase the amount of FET and/or one or more of the other federally imposed or approved fees identified above. Increasing the overall price charged to passengers could lessen demand for air travel. Additionally, federal funding to airports and/or airport bond financing could be affected through future legislation, which could result in higher fees, rates, and charges at many of the airports we serve.

Environmental. We are subject to various federal, state and local laws and regulations relating to the protection of the environment and affecting matters such as aircraft engine emissions, aircraft noise emissions, and the discharge or disposal of materials and chemicals, which laws and regulations are administered by numerous state and federal agencies. These agencies have enforcement powers similar to the DOT’s and FAA’s described above. In addition, we may be required to conduct an environmental review of the effects projected from the addition of our service at airports.

In 2016 the U.S. Environmental Protection Agency (“EPA”) formally concluded that current and projected concentrations of greenhouse gases ("GHG") emitted by various aircraft, including all of the aircraft we and other air carriers operate, threaten public health and welfare. This finding may be a precursor to increased EPA regulation of commercial aircraft emissions in the United States, as has taken effect for operations within the European Union under EU legislation. Binding international measures adopted under the auspices of the International Civil Aviation Organization (“ICAO”), a specialized agency of the United Nations, are scheduled to become effective over the next several years, with the pilot phase having begun in 2021. In January 2021 the EPA adopted regulations setting emissions standards equivalent to ICAO’s for newly-designed aircraft, with immediate effect, and for in-production aircraft, effective 2028. Similarly, in December 2021, the EPA proposed particulate matter emission standards and test procedures applicable to certain classes of jet engines (including those commonly used in the airline industry) to replace the existing smoke standards for aircraft. These proposed standards and procedures would harmonize with ICAO requirements and apply to newly-designed and in-production aircraft engines. At present, the aircraft we operate are not affected by these standards.

We anticipate that in 2022 and thereafter, legislative and regulatory concern with the environmental impacts of the air transportation industry will increase, and that the longer-term effects on our fleet and operating costs may be substantial. In September 2021, the Biden Administration announced plans to release a comprehensive aviation climate action plan in the coming months. According to the White House announcement, civil aviation accounts for 11 percent of emissions by the U.S. transportation sector as a whole. Other executive actions taken by the Administration are intended to serve the goal of reducing aviation emissions by 20% by 2030 and unlocking the potential for a zero-carbon aviation sector as of 2050. We cannot predict whether these or similar initiatives will lead to legislation that will pass the Congress or, if enacted into law, how they ultimately would apply to our operations or the airline industry.

Federal law recognizes the right of airport operators with special noise problems to implement local noise abatement procedures so long as those procedures do not interfere unreasonably with interstate and foreign commerce and the national air transportation system. These restrictions can include limiting nighttime operations, directing specific aircraft operational procedures during takeoff and initial climb, and limiting the overall number of flights at an airport. None of the airports we serve currently imposes restrictions on the number of flights or hours of operation that have a meaningful impact on our operations. It is possible one or more such airports may impose additional future restrictions with or without advance notice, which may impact our operations.

Foreign Ownership. To maintain our DOT and FAA certificates, our airline operating subsidiary and we (as the airline’s holding company) must qualify continuously as citizens of the United States within the meaning of U.S. aeronautical laws and regulations. This means we must be under the actual control of U.S. citizens and we must satisfy certain other requirements, including that our president/chief executive officer and at least two-thirds of our board of directors and other managing officers are U.S. citizens, and that not more than 25 percent of our voting stock is owned or controlled by non-U.S. citizens. The amount of non-voting stock that may be owned or controlled by non-U.S. citizens is strictly limited as well. We believe we are in compliance with these ownership and control criteria.

Other Regulations. Air carriers are subject to certain provisions of federal laws and regulations governing communications because of their extensive use of radio and other communication facilities, and are required to obtain an aeronautical radio license from the Federal Communications Commission (“FCC”). To the extent we are subject to FCC requirements, we intend to continue to comply with those requirements.

17

The quality of water used for drinking and hand-washing aboard aircraft is subject to regulation by the EPA. To the extent we are subject to EPA requirements, we intend to continue to comply with those requirements.

Working conditions of cabin crewmembers while onboard aircraft are subject to regulation by the Occupational Safety and Health Administration ("OSHA") of the Department of Labor. To the extent we are subject to OSHA requirements, we intend to continue to comply with those requirements.

Our operations may become subject to additional federal requirements in the future under certain circumstances. During a period of past fuel scarcity, air carrier access to jet fuel was subject to allocation regulations promulgated by the Department of Energy. Changes to the federal excise tax and other government fees imposed on air transportation have been proposed and implemented from time to time and may result in an increased tax burden for airlines and their passengers.

We are also subject to state and local laws, regulations, and ordinances at locations where we operate and to the rules and regulations of various local authorities that operate the airports we serve. None of the airports in the cities in which we operate have slot control, gate availability, or curfews that pose meaningful limitations on our operations. However, some airports we serve have short runways that require us to operate some flights at less than full capacity.

International air transportation, whether provided on a scheduled or charter basis, is subject to the laws, rules, regulations, and licensing requirements of the foreign countries to, from, and over which the international flights operate. Foreign laws, rules, regulations and licensing requirements governing air transportation are generally similar, in principle, to the regulatory scheme of the United States as described above, although in some cases foreign requirements are comparatively less onerous and in others, more onerous. We must comply with the laws, rules and regulations of each country to, from, or over which we operate. Our proposed U.S.-Mexico alliance with Viva, described above, is subject to prior approval by Mexico’s Federal Economic Competition Commission (COFECE) in a manner generally similar to the DOT procedure; a joint application has been submitted to COFECE. International flights are also subject to U.S. Customs and Border Protection, Immigration and Agriculture requirements and the requirements of equivalent foreign governmental agencies.

Future Laws and Regulations. Congress, the DOT, the FAA, the TSA, and other governmental agencies have under consideration, and in the future may consider and adopt, new laws, regulations, interpretations and policies regarding a wide variety of matters that could affect, directly or indirectly, our operations, ownership, and profitability. We cannot predict what other matters might be considered in the future by the FAA, the DOT, the TSA, other agencies, or Congress, nor can we judge what impact, if any, the implementation of any of these proposals or changes might have on our business.

Civil Reserve Air Fleet. We are a participant in the Civil Reserve Air Fleet (“CRAF”) Program which affords the U.S. Department of Defense the right to charter our aircraft during national emergencies when the need for military airlift exceeds the capability of available military resources. During the Persian Gulf War of 1990-91 and on other occasions, CRAF carriers were required to permit the military to use their aircraft in this manner. As a result of our CRAF participation, we are eligible to bid on and be awarded peacetime airlift contracts with the military on a preferential basis.

Item 1A. Risk Factors

Readers should carefully consider the risks described below before making an investment decision. Our business, financial condition or results of operations could be materially and adversely affected by any of these risks. The trading price of our common stock could decline due to any of these risks, and investors may lose all or part of their investment.

Risks Related to the COVID-19 Pandemic

The COVID-19 pandemic has materially and adversely affected, and may continue to materially and adversely affect, our results of operations, financial position and liquidity.

In December 2019, an outbreak of COVID-19 was identified in Wuhan, China. The COVID-19 outbreak spread throughout the world. In March 2020, the President of the United States declared a national emergency. The COVID-19 pandemic has materially and adversely affected passenger demand and bookings for air travel, thereby materially and adversely affecting operating income and cash flows from operations. As a result, we incurred a net loss of $184 million in 2020, our first net loss since 2002.

The extent of the impact of the COVID-19 pandemic on our business and our financial and operational performance will depend on future developments, including the duration, spread, severity and recurrences of the COVID-19 or similar viruses; the possible imposition of testing requirements before domestic travel; the duration and scope of related federal, state and local government restrictions; the availability and effectiveness of vaccines against COVID-19 and any variants of the virus; the extent of the impact of the COVID-19 pandemic on overall demand for air travel; and our access to capital during the pandemic, all of which are highly uncertain and cannot be predicted.

The COVID-19 pandemic has caused public health officials to recommend precautions to mitigate the spread of the virus. Since the onset of the COVID-19 pandemic, federal, state and local authorities have at various times instituted measures such as imposing self-quarantine requirements, requiring testing before entry into certain states; issuing directives forcing businesses to temporarily close, restricting air travel and issuing shelter-in-place and similar orders limiting the movement of individuals. To the extent in effect in the future, such measures may depress demand for air travel, disrupt our operations, and materially adversely affect our business.

Instances of actual or perceived risk of infection among our employees, or our service providers’ employees, could further negatively impact our operations. We could also be materially adversely affected if we are unable to effectively maintain a suitably skilled and sized workforce, address employment-related matters, or maintain satisfactory relations with our employees or our employees’ labor representatives.

Particularly during December 2021 and January 2022, widespread positive COVID tests resulted in flight crew absences which have caused us to cancel numerous flights. These cancellations resulted in unusually high irregular operations costs as we compensate passengers on company-cancelled flights for inconvenience suffered in addition to the ticket price.

Moreover, the ability to attract and retain passengers depends, in part, upon the perception and reputation of our company and the public’s concerns regarding the health and safety of air travel generally. Actual or perceived risk of infection on our flights could have a material adverse effect on the public's comfort with air travel, which could harm our reputation and business. We expect we will continue to incur COVID-19 related costs as we sanitize airplanes and implement additional hygiene-related protocol to airplanes, and take other action to limit infection among our employees and passengers.

The COVID-19 pandemic continues to rapidly evolve. The ultimate impact of the COVID-19 pandemic is highly uncertain and subject to change.

Many attractions in the leisure destinations we serve, such as Walt Disney World in Orlando, Florida and Las Vegas hotels, temporarily closed during the pandemic, and many of these have reopened with restrictions in place, which have and will continue to impact travel to these destinations.

We have entered into agreements with the U.S. Treasury with respect to funding support pursuant to the Payroll Support Programs; pursuant to which we have agreed to certain restrictions on how we operate our business and use our cash and which could limit our ability to take actions that we otherwise might have determined to be in the best interests of our company and our shareholders.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act") was signed into law. The CARES Act provides liquidity in the form of grants and loans to air carriers, such as to us. Additional benefits were made available to us under a section of the Consolidated Appropriations Act, 2021 (the “PSP Extension Act”) enacted in December 2020 and the American Rescue Plan Act enacted in March 2021 ("PSP3"). In April 2020, January 2021 and April 2021, we reached agreements with the Treasury with respect to funding support pursuant to the Payroll Support Programs under the CARES Act, the PSP Extension Act and PSP3. Pursuant to these agreements, we have agreed to certain restrictions on our business and operations, including the following:

19

We are prohibited from repurchasing our common stock and from paying cash dividends on our common stock until October 1, 2022;

We must place certain restrictions on certain higher-paid employee and executive pay, including limiting pay increases and severance pay or other benefits upon terminations, until April 1, 2023;

Until March 1, 2022, we must comply with any requirement issued by the DOT that we maintain certain scheduled air transportation service as DOT deems necessary to ensure services to any point served by us before March 1, 2020.

These restrictions may require that we take, or limit taking, actions that we believe to be in the best interests of our company and our shareholders. For example, the restrictions could require that we change certain of our business practices, risk our ability to retain key personnel, and expose us to additional costs (including increased compliance costs).

Risks Related to Allegiant

Our reputation and financial results could be harmed in the event of an accident or restrictions affecting aircraft in our fleet. 

As of February 14, 2022, our operating fleet consists exclusively of 110 Airbus A320 series aircraft, of which all but 13 were acquired used. Our aircraft range from 3 to 24 years from their manufacture date at February 14, 2022, with an average age of 15 years.

An accident involving one of our aircraft, even if fully insured, could result in a public perception that we are less safe or reliable than other airlines, which would harm our business. Further, there is no assurance that the amount of insurance we carry would be sufficient to protect us from material loss. Because we are smaller than most airlines, an accident would likely adversely affect us to a greater degree than a larger, more established airline.

In-flight emergencies affecting our aircraft, and resulting media attention, could also contribute to a public perception regarding safety concerns and a loss of business.

The FAA could suspend or restrict the use of our aircraft in the event of actual or perceived mechanical problems or safety issues while it conducts its own investigation, whether involving our aircraft or another U.S. or foreign airline’s aircraft. Our business could also be significantly harmed if the public avoids flying our aircraft due to an adverse perception of the aircraft we utilize because of safety concerns or other problems, whether real or perceived, or in the event of an accident involving these aircraft.

A breach in the security of personal or credit card data could severely damage our reputation, cause considerable additional costs and result in regulatory penalties.

We receive, retain, and transmit certain personal information about our customers. Our on-line operations also rely on the secure transmission of this customer data. We use third party systems, software, and tools in order to protect the customer data we obtain through the course of our business. Although we use these security measures to protect this customer information, a compromise of our physical or network security systems through a cyber-security attack would create the risk that our customers’ personal information might be obtained by unauthorized persons. A compromise in our security systems could adversely affect our reputation, which could impact customers' willingness to do business with us using credit or debit cards, disrupt operations, and could also result in litigation or the imposition of penalties. In addition, it could be costly to remediate.

The way businesses handle customer data is subject to increasing legislation and regulation typically intended to protect the privacy of customer data received, retained, and transmitted. We could be adversely affected if we fail to comply with existing rules or practices, or if legislation or regulations are expanded to require changes in our business practices. These privacy developments are difficult to anticipate and could adversely affect our business, financial condition, and results of operations.

We rely heavily on automated systems to operate our business and any failure of these systems could harm our business.

We depend on automated systems to operate our business, including our air reservation system, telecommunication systems, our website, and other automated systems. Our continuing initiatives to enhance the capabilities of our automated systems could increase the risk of automation failures. Any failure by us to handle our automation needs could negatively affect our internet sales (on which we rely heavily) and customer service, and result in lost revenues and increased costs.

Our website and reservation system must be able to accommodate a high volume of traffic and deliver necessary functionality to support our operations. Our automated systems cannot be completely protected against events that are beyond our control, such as natural disasters, telecommunications failures, malware, ransom ware, security breaches or cyber-security attacks. Although we have implemented security measures and have information systems disaster recovery plans in place, we cannot assure investors that these measures are adequate to prevent disruptions or that the insurance would cover all losses. Substantial or repeated website, reservations system, or telecommunication system failures could decrease the attractiveness of our services.

20

Any disruption to these systems could result in the loss of important data and revenue, increase in expenses, and harm to our business.

Increases in fuel prices or unavailability of fuel would harm our business and profitability.

Fuel costs constituted approximately 30.5 percent of our total operating expenses in 2021 and the average cost per gallon increased by 45.3 percent in 2021 over 2020 and has continued to increase in first quarter 2022. Significant increases in fuel costs have negatively affected our operating results in the past, and future fuel cost volatility could materially affect our financial condition and results of operations.

Both the cost and availability of aircraft fuel are subject to many economic and political factors and events occurring throughout the world over which we have no control. Meteorological events may also result in short-term disruptions in the fuel supply. Aircraft fuel availability is also subject to periods of market surplus and shortage, and is affected by demand for heating oil, gasoline, and other petroleum products. Due to the effect of these events on the price and availability of aircraft fuel, our ability to control this cost is limited, and the price and future availability of fuel cannot be predicted with any degree of certainty. Due to the high percentage of our operating costs represented by fuel, a relatively small increase in the price of fuel could have a significantly negative impact on our operating costs. A fuel supply shortage or higher fuel prices could result in reduction of our service during the period affected.

We have made a business decision not to purchase financial derivatives to hedge against increases in the cost of fuel. This decision may make our operating results more vulnerable to the impact of fuel price increases.

Increased labor costs could result from industry conditions and could be impacted by labor-related disruptions.

Labor costs excluding the impact of the CARES Act grants constituted approximately 33.5 percent of our total operating costs in 2021, our largest expense line item. Labor costs are generally rising and it has become more difficult to find suitable candidates in the current economic environment.

Further, we have four employee groups (pilots, flight attendants, flight dispatchers and maintenance technicians) which have elected union representation. These groups represent approximately 71.0 percent of our employees.

In 2016, we reached a collective bargaining agreement with the International Brotherhood of Teamsters, representing our pilots. The pilot agreement is now amendable and the parties are in the process of negotiating a new labor agreement.

An agreement with the Transport Workers Union for the flight attendant group was approved in 2017 and becomes amendable during 2022. We also have agreements with the International Brotherhood of Teamsters for the flight dispatchers which was approved in May 2019 and for maintenance technicians which was approved in October 2021. These agreements will impact our costs over their respective five-year contract terms.

Future union contracts with these, or other, work groups could put additional pressure on our labor costs.

If we are unable to reach agreement on the terms of collective bargaining agreements in the future, or we experience wide-spread employee dissatisfaction, we could be subject to work slowdowns or stoppages. Any of these events could have an adverse effect on our operations and future results.

The successful development of our first Sunseeker Resort is dependent on commercial and economic factors, some of which are beyond our control.

We are developing a hotel resort in Southwest Florida. After suspension of construction during the pandemic, construction recommenced in August 2021. The successful development of the project will be subject to various risks inherent in construction projects (such as supply chain issues, cost overruns and construction delays) as well as risks of gaining sufficient interest from vacationers to stay in our hotel and suites, the desirability of the project’s location, competition and the ability to profitably operate the hotel and related offerings once open.

The success of our alliance with Viva Aerobus will depend on our ability to obtain necessary government approvals and other factors.

We will be able to implement the joint alliance with Viva Aerobus as planned only if the DOT grants us antitrust immunity and we receive similar approval from Mexican authorities. Although we believe we should qualify for these approvals, there can be no assurance we will be able to obtain them on a timely basis, or at all.

Many of the U.S. airports from which we hope to offer this service do not currently qualify to offer international service. The initiation of this service from these airports will depend on the airport satisfying the requirements for international service, for which we can provide no assurance.

21

Prior to offering international service on our website, we will need to implement the necessary systems to accommodate international travel and to meet the various requirements imposed by the U.S. and Mexico. There is no assurance that these requirements will be met in time for the expected launch of these services.

For Mexican routes to be operated by Viva Aerobus, we will be relying on them to provide our customers with the quality flight experience our customers expect when traveling on our airline. Otherwise, the success of the joint alliance and our reputation may suffer.

Increases in taxes could impact demand for our services.

In 2022, Congress may consider legislation that could increase the amount of Federal Excise Tax (“FET”) and/or one or more of the other government fees imposed on air travel. By increasing the overall price charged to passengers, any additional taxes or fees could lessen the demand for air travel or force carriers to lower fares to maintain demand. Increased taxes and fees per passenger may impact our load factors more than other airlines as our lower fares are designed to stimulate demand for our services.

FAA limitations could impact our ability to grow in the future.

As with all airlines, the FAA must approve all aircraft and cities to be added to our operation specifications. Although there are no restrictions in place at the current time, future limitations from the FAA could potentially hinder our growth.

Unfavorable economic conditions may adversely affect travel from our markets to our leisure destinations.

The airline industry is particularly sensitive to changes in economic conditions. Unfavorable U.S. economic conditions have historically driven changes in travel patterns and have resulted in reduced discretionary spending for leisure travel. Unfavorable economic conditions could impact demand for airline travel in our under-served cities to our leisure destinations. During difficult economic times, we may be unable to raise prices in response to fuel cost increases, labor, or other operating costs, which could adversely affect our results of operations and financial condition.

Our indebtedness, debt service obligations and other commitments could adversely affect our business, financial condition and results of operations as well as limit our ability to react to changes in the economy or our industry and prevent us from servicing our debt and operating our business.

Our debt and finance lease obligations as of December 31, 2021 totaled $1.74 billion net of related costs. In addition, in December 2021, we entered into a purchase agreement with The Boeing Company to purchase 50 Boeing 737 MAX aircraft to deliver in 2023 to 2025. This indebtedness, the Boeing purchase agreement and other commitments with debt service and fixed charge obligations could:

–make it more difficult for us to satisfy our obligations with respect to our indebtedness, and any failure to comply with the obligations of any of our debt instruments, including financial and other restrictive covenants, could result in an event of default under agreements governing our indebtedness;

–make it more difficult to satisfy our other future obligations, including our obligations to pay the purchase price in respect of current and future aircraft purchase contracts;

–require us to dedicate a substantial portion of our cash flow to pay principal and interest on our debt, which will reduce the funds available to fund internal growth through working capital, capital expenditures, and for other purposes;

–limit our flexibility in planning for, or reacting to, changes in our business, the competitive environment, legislation and our industry;

–make us more vulnerable to adverse changes in our business, economic, industry, market or competitive conditions and adverse changes in government regulation;

–expose us to interest rate and pricing increases on indebtedness and financing arrangements;

–restrict us from pursuing strategic acquisitions or exploiting certain business opportunities;

–subject us to a greater risk of non-compliance with financial and other restrictive covenants in financing arrangements;

–limit, among other things, our ability to obtain additional financing for working capital, capital expenditures, debt service requirements, execution of our business strategy and other purposes or raise equity capital in the future and increasing the costs of such additional financings; and

–place us at a competitive disadvantage compared to our competitors who may not be as highly leveraged or who have less debt in relation to cash flow.

In addition, our ability to service our indebtedness will depend on our future performance, which will be affected by prevailing economic conditions and financial, business, regulatory and other factors. Many of these factors are beyond our control and could materially adversely affect our business, results of operations, cash flows and financial condition.

At maturity, or in the event of an acceleration of payment obligations, we may be unable to pay our outstanding indebtedness with our cash and cash equivalents then on hand. In such event, we would be required to seek alternative sources of funding, which may not be available on commercially reasonable terms, terms as favorable as our current agreements, or at all. If we are unable to refinance our indebtedness or find alternative means of financing our operations, we may be required to take actions that are inconsistent with our current business practices or strategy.

22

The announced upcoming discontinuance of publishing LIBOR rates may impact the cost or availability of financing for us.

A large portion of our variable rate indebtedness ( $927.5 million of outstanding principal as of December 31, 2021) references the London interbank offered rates ("LIBOR") as a benchmark for establishing the interest rate. LIBOR is expected to be phased out by the end of 2022. Although all of our LIBOR-based borrowings offer prepayment without penalty, uncertainty as to the nature of alternative reference rates and as to potential changes or other reforms to LIBOR may adversely impact the cost and availability of borrowings on which we have relied and intend to rely in the future.

Covenants in our senior secured term loan, senior secured notes and construction loan could limit how we conduct our business, which could affect our long-term growth potential.

As of December 31, 2021, the principal balances of our Term Loan and Senior Secured Notes totaled $685.9 million and the principal balance of our Sunseeker construction loan was $175.0 million. The loan agreements contain covenants limiting our ability to, among other things, make certain types of restricted payments, including paying dividends, incur debt or liens, merge or consolidate with others, dispose of assets, enter into certain transactions with affiliates, engage in certain business activities or make certain investments. In addition, the loan agreements contain financial covenants, including requiring us, at the end of each calendar quarter, to maintain a maximum total leverage ratio of 5.00:1.00 and to maintain a minimum aggregate amount of liquidity of $300.0 million. We have pledged our assets to secure the Term Loan and Senior Secured Notes with the exceptions of aircraft and aircraft engines, the Sunseeker Resort and certain other exceptions. The Sunseeker Resort is pledged to secure a $350.0 million construction loan agreement to finance the completion of the construction of the Resort. This will limit our ability to obtain debt secured by these pledged assets while these loans are outstanding.

These loan agreements contain various events of default (including failure to comply with the covenants under the loan agreements), and upon an event of default the lenders may, subject to various cure rights, require the immediate payment of all amounts outstanding under the these loans.

As a result of these restrictive covenants, we may be limited in how we conduct business, and we may be unable to raise additional debt or equity financing to operate during difficult times or to take advantage of new business opportunities.

Any inability to obtain financing for aircraft under contract could harm our fleet growth plan.

We typically finance our aircraft through debt financing after purchase. Although we believe debt financing will be available

for the aircraft we will acquire and for required pre-delivery deposits for our Boeing order, we cannot provide assurance that we will be able to secure such financing on terms attractive to us or at all. To the extent we cannot secure such financing on acceptable terms or at all, we may be required to modify our aircraft acquisition plans, incur higher than anticipated financing costs, or use more of our cash balances for aircraft acquisitions than we currently expect.

Our maintenance costs may increase as our fleet ages.

In general, the cost to maintain aircraft increases as they age, and exceeds the cost to maintain newer aircraft. FAA regulations, including the Aging Aircraft Airworthiness Directives, require additional and enhanced maintenance inspections for older aircraft. These regulations can directly impact the frequency of inspections as an aircraft ages, and vary by aircraft or engine type, depending on the unique characteristics of each aircraft and/or engine.

In addition, we may be required to comply with any future law changes, regulations, or airworthiness directives. We cannot assure investors our maintenance costs will not exceed our expectations.

We rely on third parties to provide us with facilities, aircraft and services that are integral to our business.

We have entered into agreements with third party contractors to provide certain facilities and services required for our operations, such as aircraft maintenance, ground handling, baggage services, and ticket counter space. Our reliance on others to provide essential services on our behalf gives us less control over costs and the efficiency, timeliness and quality of contract services.

We also rely on Boeing and the owners of used aircraft under contract to be able to deliver aircraft in accordance with the terms of executed agreements in a timely manner. Our planned initiation of service with these aircraft in the future could be adversely affected if the third parties fail to perform as contractually obligated. 

23

We may not be able to maintain or grow our ancillary revenues.

Our business strategy includes expanding our ancillary products and services. We cannot ensure that passengers will pay for additional ancillary products and services we offer in the future, or that they will continue to pay for the ancillary products and services we currently offer. Regulatory changes could also adversely affect our ancillary revenue opportunities. Failure to maintain our ancillary revenues could have a material adverse effect on our results of operations, financial condition and stock price. If we are unable to maintain and grow these revenues, we may be unable to execute our strategy to continue to offer low base fares in order to stimulate demand.

Our business could be harmed if we lose the services of our key personnel.

Our business depends upon the efforts of our chief executive officer, Maurice J. Gallagher, Jr., president, John Redmond, and a small number of executive management and operating personnel. As of June 1, 2022, Mr. Gallagher will transition from chief executive officer to executive chairman and Mr. Redmond will assume the role of president and chief executive officer. We do not currently maintain key-man life insurance on Mr. Gallagher, Mr. Redmond or any other executives. We may have difficulty replacing management or other key personnel who leave and, therefore, the loss of the services of any of these individuals could harm our business.

Risks Associated with the Airline and Travel Industry

Our operating results could be affected by outbreaks of communicable diseases.

As has resulted from the COVID-19 pandemic, contagious illness and fear of contagion could have a material adverse impact on the airline industry. Any general reduction in airline passenger traffic as a result of an outbreak of disease or other travel advisories could dampen demand for our services even if not applicable to our markets. Resulting decreases in passenger volume would harm our load factors, could increase our cost per passenger and adversely affect our operating results.

The airline industry is highly competitive and future competition in our under-served markets could harm our business.

The airline industry is highly competitive. The under-served cities we serve on a scheduled basis have traditionally attracted considerably less attention from our potential competitors than larger markets, and in most of our small city markets, we are the only provider of nonstop service to our leisure destinations. If other airlines or new airline start-ups begin to provide nonstop services to and from these or similar markets, or otherwise target these or similar markets, the increase in the amount of direct or indirect competition could cause us to reconsider service to affected markets, could impact our margins or could impact our future planned service.

A future act of terrorism, the threat of such acts, or escalation of U.S. military involvement overseas could adversely affect our industry.

Even if not directed at the airline industry, a future act of terrorism, the threat of such acts, or escalation of U.S. military involvement overseas could have an adverse effect on the airline industry. In the event of a terrorist attack, the industry would likely experience significantly reduced demand for travel services. These actions, or consequences resulting from these actions, would likely harm our business and the airline and travel industry. If we are called on to provide aircraft in the event of national emergencies as a result of our participation in the CRAF program, our operations would be disrupted.

Changes in government laws and regulations imposing additional requirements and restrictions on our operations could increase our operating costs.

Airlines are subject to extensive regulatory and legal compliance requirements, both domestically and internationally, that involve significant costs. In the last several years, the FAA has issued a number of directives and other regulations relating to the maintenance and operation of aircraft that have required us to incur significant expenditures. FAA requirements cover, among other things, retirement of older aircraft, fleet integration of newer aircraft, safety management systems, collision avoidance systems, airborne windshear avoidance systems, noise abatement, weight and payload limits, assumed average passenger weight, employee drug and alcohol testing, pilot and flight attendant duty time limitations, and increased inspection and maintenance procedures to be conducted on aging aircraft. The future cost of complying with these and other laws, rules and regulations, including new federal legislative and DOT regulatory requirements in the consumer-protection area, cannot be predicted and could significantly increase our costs of doing business.

Over the past 13 years the DOT has adopted revisions and expansions to a variety of its consumer protection regulations and policies. Additional new regulations or policies may be proposed or take effect in 2022 or thereafter, whether on DOT's initiative or as directed by Congress. We are not able to predict the impact of any new consumer protection rules on our business, though we monitor the progress of potential rulings. We are subject to fines or other enforcement actions if the DOT believes we are not in compliance with these or other rules or regulations or with the federal consumer protection laws administered by the DOT.

Even if our practices are found to be in compliance with the DOT rules, we could incur substantial costs defending our practices. Additionally, federal funding to airports and/or airport bond financing could be affected through future deficit reduction legislation,

24

which could result in higher fees, rates, and charges at many of the airports we serve. From time to time legislative proposals have been made to re-regulate the airline industry in varying degrees - for example, to specify minimum seat-size and legroom requirements - which if adopted could affect our costs materially.

We (i.e., our airline subsidiary) and Viva, a Mexican airline, recently submitted to DOT a joint application requesting approval of and antitrust immunity for a comprehensive alliance agreement applicable to all routes we and/or Viva may operate between points in the United States and points in Mexico. We and Viva have asked DOT to provide final approval of the alliance agreement and to issue antitrust immunity by July 31, 2022, to help facilitate inauguration of service under the agreement in the first quarter of 2023. Some similar applications involving other carriers have taken DOT far longer to process, and there is no assurance our proposed time frame will be achieved. Nor is there assurance DOT will ultimately approve the agreement and grant antitrust immunity. Both parties have stated they do not intend to proceed under the agreement in the absence of antitrust immunity. In addition, performance under the agreement is contingent upon Mexican regulatory approval, as well as Mexico reattaining Category 1 status under the FAA’s International Aviation Safety Assessment program, a matter within the control of the FAA and the Government of Mexico. An adverse outcome in one or more of these respects would likely thwart our plans to enter the U.S.-Mexico market for a number of years, despite the effort and expense we have incurred and continue to incur on the project.

We anticipate that in 2022 and thereafter, legislative and regulatory concern with the environmental impacts of the air transportation industry will increase, and that the longer-term effects on our fleet and operating costs may be substantial. In the past, legislation to address climate change issues as they relate to the transportation industry has been introduced in the U.S. Congress, including a proposal to require transportation fuel producers and importers to acquire market-based allowances to offset the emissions resulting from combustion of their fuels. Similarly, as recently as February 2021, legislation was introduced in the U.S. Congress to incentivize the production of sustainable aviation fuel (also known as biofuel) and to assist the aviation industry in reducing emissions. In September 2021, the Biden Administration announced plans to release a comprehensive aviation climate action plan in the coming months. According to the White House announcement, civil aviation accounts for 11 percent of emissions by the U.S. transportation sector as a whole. Other executive actions taken by the Administration are intended to serve the goal of reducing aviation emissions by 20% by 2030 and unlocking the potential for a zero-carbon aviation sector as of 2050. We cannot predict whether this or any similar legislation will pass the Congress or, if enacted into law, how it ultimately would apply to our operations or the airline industry.

In addition, the EPA concluded in 2016 that current and projected concentrations of GHG emitted by various aircraft, including all of the aircraft we and other carriers operate, threaten public health and welfare. This finding may be a precursor to increased EPA regulation of commercial aircraft emissions in the United States, as has taken effect for operations within the European Union under EU legislation. Binding international measures adopted under the auspices of the International Civil Aviation Organization (“ICAO”), a specialized agency of the United Nations, are scheduled to become effective over the next several years, with the pilot phase having begun in 2021. In January 2021 the EPA adopted regulations setting emissions standards equivalent to ICAO’s for newly-designed aircraft, with immediate effect, and for in-production aircraft, effective 2028. Similarly, in December 2021, the EPA proposed particulate matter emission standards and test procedures applicable to certain classes of jet engines (including those commonly used in the airline industry) to replace the existing smoke standards for aircraft. These proposed standards and procedures would harmonize with ICAO requirements and apply to newly-designed and in-production aircraft engines. At present, the aircraft we operate are not affected by these standards, although as noted, we anticipate an ever-increasing legislative and regulatory focus on aviation’s impacts on the environment. These developments and any additional legislation or regulations addressing climate change are likely to increase our costs of doing business in the future and the increases could be material.

With respect to aircraft weight and balance, consumer protection, climate change, taxation, and other matters affecting the airline industry, whether the source of new requirements is legislative or regulatory, increased costs will adversely affect our profitability if we are unable to pass the costs on to our customers or adjust our operations to offset the new costs.

Existing and proposed state-specific labor laws could affect our ability to schedule and operate flights efficiently, and as a result could increase our operating costs and liability exposure.

Various states and localities across the country are attempting to impose requirements, such as wage and hour requirements, meal and rest break and sick leave laws, on flight attendants and pilots (“flight crew”) who spend the vast majority of their working hours in the air and in various states and jurisdictions on a daily basis. These requirements would create significant operational challenges for air carriers by creating a patchwork of state and local laws which undermine the federal deregulation of the airline industry and, in theory, could require airlines to simultaneously comply with rules which conflict with those of other jurisdictions and the provisions of labor agreements. Courts continue to remain divided on whether federal deregulation preempts these state laws and Congress has not addressed the issue. The impact on flight crew staffing, pay and scheduling technology may potentially increase our costs of doing business and could make certain routes cost prohibitive. Flight crews have filed class action lawsuits against air carriers in a number of states with varied results and, in many cases, the results have been appealed. We have been sued in California by a flight attendant seeking class action certification on claims involving these issues. Such suits are costly to defend and could result in sizeable liability exposure for any air carrier.

25

Airlines are often affected by factors beyond their control, including air traffic congestion, weather conditions, increased security measures, and a reduction in demand to any particular market, any of which could harm our operating results and financial condition.

Like other airlines, we are subject to delays caused by factors beyond our control, including air traffic congestion at airports and en route, adverse weather conditions, increased security measures, and the outbreak of disease. Delays frustrate passengers and increase costs, which in turn could affect profitability. During periods of fog, snow, rain, storms or other adverse weather conditions, flights may be canceled or significantly delayed. Cancellations or delays due to weather conditions, traffic control problems, and breaches in security could harm our operating results and financial condition.

A substantial proportion of our scheduled flights have Las Vegas, Orlando, Phoenix, Tampa/St. Petersburg, Los Angeles, Punta Gorda, or Destin as either their destination or origin. Our business could be harmed by any circumstances causing a reduction in demand for air transportation to one or more of these markets, or our other leisure destinations, such as adverse changes in local economic conditions, negative public perception of the particular city, significant price increases, or the impact of future terrorist attacks or natural disasters.

Risks Related to Our Stock Price

The market price of our common stock may be volatile, which could cause the value of an investment in our stock to decline.

The market price of our common stock may fluctuate substantially due to a variety of factors, many of which are beyond our control, including:

–the impact of pandemics and other communicable diseases on air travel and any related government restrictions impacting air travel

–fuel price volatility, and the effect of economic and geopolitical factors and worldwide oil supply and consumption on fuel availability

–announcements concerning our competitors, new market entrants, the airline industry, or the economy in general

–strategic actions by us or our competitors, such as acquisitions or restructurings

–media reports and publications about the safety of our aircraft or the aircraft types we operate

–new regulatory pronouncements and changes in regulatory guidelines

–announcements concerning our business strategy

–our ability to grow service in the future as rapidly as the market anticipates as we continue to add more cities to our network

–general and industry-specific economic conditions

–changes in financial estimates or recommendations by securities analysts

–substantial sales of our common stock or other actions by investors with significant shareholdings

–additional issuances of our common stock

–labor costs or work actions

–general market conditions

The stock markets in general have experienced substantial volatility that has often been unrelated to the operating performance of particular companies. These types of broad market fluctuations may adversely affect the trading price of our common stock.

In the past, stockholders have sometimes instituted securities class action litigation against companies following periods of volatility in the market price of their securities. Although we have insurance to cover these claims, these lawsuits or similar litigation could result in substantial costs, divert management’s attention and resources, and harm our business or results of operations.

26

Other companies may have difficulty acquiring us, even if doing so would benefit our stockholders, due to provisions under our corporate charter and bylaws, as well as Nevada law.

Provisions in our articles of incorporation, our bylaws, and under Nevada law could make it more difficult for other companies to acquire us, even if doing so would benefit our stockholders. Our articles of incorporation and bylaws contain the following provisions, among others, which may inhibit an acquisition of our company by a third party:

–advance notification procedures for matters to be brought before stockholder meetings

–a limitation on who may call stockholder meetings

–the ability of our board of directors to issue up to 5,000,000 shares of preferred stock without a stockholder vote

We are also subject to provisions of Nevada law that prohibit us from engaging in any business combination with any “interested stockholder,” meaning generally that a stockholder who beneficially owns 10 percent or more of our stock cannot acquire us for a period of time after the date this person became an interested stockholder, unless various conditions are met, such as approval of the transaction by our board of directors and stockholders.

Under U.S. laws and the regulations of the DOT, we must be under the actual control of U.S. citizens at all times. By law, our president/CEO and at least two-thirds of our board of directors and other managing officers must be U.S. citizens and not more than 25 percent of our voting stock may be owned or controlled by non-U.S. citizens (although consistent with DOT policy, our overall foreign economic ownership may be as high as 49 percent). Any of these restrictions as well as DOT prior-approval requirements could have the effect of delaying or preventing a change in control.

Our corporate charter and bylaws include provisions limiting voting by non-U.S. citizens.

To comply with restrictions imposed by federal law on foreign ownership of U.S. airlines, our articles of incorporation and bylaws restrict voting of shares of our capital stock by non-U.S. citizens. The restrictions imposed by federal law currently require no more than 25 percent of our stock be voted, directly or indirectly, by persons who are not U.S. citizens, and that our president and at least two-thirds of the members of our board of directors be U.S. citizens. Our bylaws provide no shares of our capital stock may be voted by or at the direction of non-U.S. citizens unless such shares are registered on a separate stock record, which we refer to as the foreign stock record. Our bylaws further provide no shares of our capital stock will be registered on the foreign stock record if the amount so registered would exceed the foreign ownership restrictions imposed by federal law. Registration on the foreign stock record is made in chronological order based on the date we receive a written request for registration. Non-U.S. citizens will be able to own and vote shares of our common stock only if the combined ownership by all non-U.S. citizens does not violate these requirements.

Ground Facilities

We lease facilities at the majority of our leisure destinations and several other airports we serve. Our leases for terminal passenger service facilities (which include ticket counter and gate space, and operations support areas) generally have a term ranging from month-to-month to several years, and may typically be terminated with a 30 to 90 day notice. We have also entered into use agreements at each of the airports we serve which provide for non-exclusive use of runways, taxiways, and other facilities. Landing fees under these agreements are based on the number of landings and weight of the aircraft.

The following details the airport locations we utilize as operational bases as of February 14, 2022:

Airport	Location
Asheville Regional Airport	Fletcher, North Carolina
Austin-Bergstrom International Airport	Austin, Texas

As of February 14, 2022, there were 175 holders of record of our common stock. Because many of our shares are held by brokers and other institutions on behalf of shareholders, we are unable to estimate the total number of beneficial holders.

Securities Authorized for Issuance under Equity Compensation Plans

The following table provides information regarding options, warrants and other rights to acquire equity securities under our equity compensation plans as of December 31, 2021:

	Number of Securities to be Issued upon Exercise of Outstanding Options, Warrants and Rights	Weighted-Average Exercise Price of Outstanding Options, Warrants and Rights	Number of Securities Remaining Available for Future Issuance under Equity Compensation Plans(2)
Equity compensation plans approved by security holders(1)	—	N/A	240,792

(1)There are no securities to be issued under any equity compensation plans not approved by our security holders.

(2)Our 2016 Long-Term Incentive Plan applies a fungible ratio such that a full-value award, such as a restricted stock grant or restricted stock unit grant, will be counted at two times its number for purposes of the plan limit. As a result, a maximum of 120,396 shares of restricted stock are remaining for future issuance under the 2016 Long-Term Incentive Plan.

Dividend Policy

We paid a quarterly dividend from 2015 through first quarter 2020 when we suspended all cash dividends upon the onset of the pandemic. In addition, in connection with the Payroll Support Program Agreements we entered into with the Treasury, we are required to comply with the relevant provisions of the CARES Act, PSP Extension Act and PSP3, including those prohibiting the repurchase of common stock and the payment of cash dividends until September 30, 2022. As a result, we have not paid any dividend since the quarterly dividend which was declared and paid in first quarter of 2020.    

Our Repurchases of Equity Securities

We agreed not to repurchase shares through September 30, 2022 in connection with receipt of financial support under the Payroll Support Program Agreements.

The following terms used in this section and elsewhere in this annual report have the meanings indicated below:

“Available seat miles” or “ASMs” represents the number of seats available for passengers multiplied by the number of miles the seats are flown.

“Average fuel cost per gallon” represents total aircraft fuel expense for our total system divided by the total number of fuel gallons consumed in our total system.

“Average stage length” represents the average number of miles flown per flight. 

“Block hours” represents the number of hours during which the aircraft is in revenue service, measured from the time of gate departure until the time of gate arrival at the destination.

“Load factor” represents the percentage of aircraft seating capacity utilized (revenue passenger miles divided by available seat miles).

“Operating expense per ASM” or “CASM” represents operating expenses divided by total system available seat miles.

“Operating CASM, excluding fuel” represents operating expenses, less aircraft fuel expense, divided by total system available seat miles. This statistic provides management and investors the ability to measure and monitor our cost performance absent fuel price volatility. Both the cost and availability of fuel are subject to many economic and political factors and therefore are beyond our control.

“Passengers” represents the total number of passengers flown on all flight segments.

“Revenue passenger miles” or “RPMs” represents the number of miles flown by revenue passengers.

“Total passenger revenue per ASM” or “TRASM” represents total passenger revenue divided by scheduled service available seat miles.

39

NETWORK

We manage capacity and route expansion through optimization of our flight schedule to, among other things, better match demand in certain markets. We continually adjust our network through the addition of new markets and routes, adjusting the frequencies into existing markets, and exiting under-performing markets, as we seek to achieve and maintain profitability on each route we serve.

TRENDS

COVID-19

The COVID-19 pandemic has significantly impacted our operating results for the years ended December 31, 2020 and 2021 and may continue to do so into the future. We believe that demand in the foreseeable future will continue to fluctuate in response to fluctuations in COVID-19 cases, variants of the virus, hospitalizations, deaths, treatment efficacy, the availability of vaccines, CDC recommendations, and government restrictions.

Despite the pandemic and airline industry challenges, since the beginning of 2021 and through December 31, 2021, we have announced service on 111 new routes and to eight new cities, including seasonal and temporary routes. We will continue to manage capacity to meet demand, which we believe is a core strength of our business model.

Boeing Agreement

In December 2021, we signed an agreement with The Boeing Company to purchase 50 newly manufactured 737MAX aircraft scheduled to be delivered in 2023 to 2025 with options to purchase an additional 50 737’s. We believe this new aircraft purchase is complimentary with our low cost strategy based on of our intent to retain ownership of the aircraft, the longer useful life for depreciation purposes, expected fuel savings and operational reliability from the use of these new aircraft.

Growth

We plan to continue to grow our aircraft fleet and route network and have executed agreements to acquire 69 incremental aircraft since January 1, 2021, of which 60 have yet to be delivered as of February 14, 2022. Our future profitability will be affected by the success of our growth initiatives.

Operations

Noncontrollable and controllable factors have contributed to a higher than normal level of cancellations beginning in second quarter 2021 and have resulted in increased irregular operations costs. The noncontrollable factors include labor shortages, weather, TSA delays generally and particularly at smaller airports, airport overcrowding and supply chain disruptions. Controllable issues relate to various aspects of our operations as we had to readjust to providing peak capacity while also facing a number of external issues as indicated above. We believe these issues are not unique to Allegiant nor do we believe they are systemic. Our irregular operations costs are also impacted by our policy to compensate passengers for their inconvenience in addition to the ticket price, which we believe is unique and incremental to what other airlines provide on cancellations.

We are investing incrementally in our operations in an attempt to improve performance and this may put pressure on unit costs in the near term. However, if these problems persist, we may suffer reputational damage and incur higher costs for irregular operations.

Union Negotiations

The collective bargaining agreement with our pilots is currently amendable and the parties have begun to discuss the terms of a new labor agreement for this work group. The terms of any new collective bargaining agreement will impact our costs over the term of the contract.

Aircraft Fuel

The cost of fuel is volatile, as it is subject to many economic and geopolitical factors we can neither control nor predict. Significant increases in fuel costs could materially affect our operating results and profitability. We have not sought to use financial derivative products to hedge our exposure to fuel price volatility, nor do we have any plans to do so in the future.

Engagement of Schneider Electric as ESG Consultant

We have entered into a three-year partnership with Schneider Electric to help us develop an Environmental, Social and Governance (ESG) program including:

–Identifying and prioritizing relevant ESG topics through a materiality assessment

–Establishing ESG goals and environmental goal achievement plans

–Developing an inaugural ESG report referencing the Global Reporting Initiative (GRI) and Sustainability Accounting Standards Board (SASB) frameworks

–Providing ongoing carbon emissions reporting of Scope 1, 2 and 3 greenhouse gas (GHG) emissions

–Supporting the communications efforts around our ESG program

Viva Aerobus Alliance

In December 2021, we announced plans for a fully-integrated commercial alliance agreement with Viva Aerobus, designed to expand options for nonstop leisure air travel between our markets in the United States and Mexico. We and Viva Aerobus have

41

submitted a joint application to the DOT requesting approval of and antitrust immunity for the alliance. The transactions are also subject to clearance by the Mexican Federal Economic Competition Commission.

We and Viva Aerobus currently expect to offer flights under the alliance beginning in the first quarter of 2023, pending governmental approval of the applications.

Sunseeker Resort

We recommenced the construction of our Sunseeker Resort in Southwest Florida in August 2021. In October 2021, we entered into a credit agreement with affiliates of Castlelake L.P. to finance up to $350 million of the remaining construction cost. With this funding, we expect to open the Resort in early 2023.

Our Operating Expenses

A brief description of the items included in our operating expense line items follows.

Aircraft fuel expense includes the cost of aircraft fuel, fuel taxes, into plane fees and airport fuel flowage, storage or through-put fees.

Salaries and benefits expense includes wages, salaries, and employee bonuses, sales commissions for in-flight personnel, as well as expenses associated with employee benefit plans, stock compensation expense related to equity grants, and employer payroll taxes.

RESULTS OF OPERATIONS

2021 compared to 2020

Operations during 2020 consisted of two months of pre-pandemic activity and the period from March 2020 through December 2020 which was substantially impacted by the pandemic. The comparisons below of the results for 2021 and 2020 should be read with this in mind.

As comparisons of our 2021 results to 2020 reflect disproportionate changes due to the impact of the pandemic on air travel, we have also provided analysis of certain revenue and expense line items to 2019 results where helpful to understand trends in our performance.

Operating Revenue

Passenger revenue. Passenger revenue increased 75.0 percent in 2021 compared with 2020. The increase was primarily attributable to the effects of COVID-19 in 2020, where a significant decline in passenger demand impacted operations from March to December 2020. Scheduled service passengers and average base fares in 2021 were up 57.9 percent and 11.5 percent, respectively, over 2020.

As compared to 2019, passenger revenue decreased by 6.2 percent, as the impact of a 13.6 percentage point decline in scheduled service load factor was partially offset by a 9.5 percent increase in capacity as we continued to restore capacity from 2020 levels and expand our route network.

Air ancillary average fare for 2021 increased by 10.0 percent when compared to 2020 and 12.3 percent when compared to 2019, the increase over 2019 more than offsetting a 5.0 percent decline in average base fares. The increase was primarily driven by an increased take rate on bundled air ancillary products.

Third party products revenue. Third party products revenue for 2021 increased 86.1 percent over 2020 and 23.5 percent when compared to 2019. The increase from 2020 was primarily the result of greater travel demand for rental cars and hotels than the early part of the pandemic. The increase from 2019 was attributable to growth in our co-branded credit card revenues, which more than offset declines in rental car days and hotel room nights.

Fixed fee contract revenue. Fixed fee contract revenue for 2021 increased 53.3 percent compared with 2020. This was primarily due to a 37.1 percent increase in related departures due to increased charter activity when compared to 2020, which was most impacted by the pandemic. During 2021, ad-hoc charters increased by 181.1 percent over 2020 levels as we benefited from March Madness which did not occur in 2020 due to the pandemic and also the return of a full college football season.

Fixed fee contract revenue for 2021 as compared to 2019 decreased by 36.7 percent due to continuing depressed demand for group charters compared to pre-pandemic periods.

Other revenue. Other revenue decreased by 87.6 percent for 2021, when compared to 2020. The decrease is due to decreased activity in our non-airline subsidiaries, including the closure of the family entertainment centers in 2020 and the sale of our Teesnap golf management business in April 2021.

Operating Expenses

The following table presents operating unit costs on a per ASM basis, defined as Operating CASM, for the indicated periods. Excluding fuel on a per ASM basis provides management and investors the ability to measure and monitor our cost performance absent fuel price volatility. Both the cost and availability of fuel are subject to many economic and political factors beyond our control.

Salaries and benefits expense. Salaries and benefits expense increased $106.7 million, or 28.3 percent, in 2021 compared to 2020. The increase is largely due to a 15.4 percent year over year increase in the average number of full-time equivalent employees. The increase was also driven by voluntary leave programs offered to employees, voluntary pay reductions, and suspension of the bonus accrual that were in effect during 2020 during the early stages of the pandemic.

Salaries and benefits expense increased by $34.1 million or 7.6 percent as compared to 2019. The increase is driven by a 2.2 percent increase in the average number of full time equivalent employees and annual increases in crew pay.

Aircraft fuel expense. Aircraft fuel expense increased $218.4 million, or 98.5 percent, in 2021 compared to the same period in 2020. The increase was due to the recovery from the COVID-19 pandemic as departures increased by 33.1 percent resulting in an increase of 36.9 percent in fuel gallons consumed along with a 45.3 percent increase in average fuel cost per gallon.

Aircraft fuel expense increased by $12.4 million or 2.9 percent in 2021 compared to 2019. This was primarily driven by a 5.9 percent increase in departures resulting in a 4.2 percent increase in fuel gallons consumed offset by a 1.4 percent decrease in average fuel cost per gallon.

Station operations expense. Station operations expense during 2021 increased $98.6 million or 68.1 percent over 2020 primarily due to a 33.1 percent increase in departures, increased costs associated with irregular operations, and increased airport and landing fees.

As compared to 2019, station operations expense increased by $71.9 million or 42.0 percent due to a 5.9 percent increase in departures, increased costs associated with irregular operations and airport fees. Irregular operations costs in 2021 were significantly attributable to COVID absences of flight crews which were highest in December 2021. These absences resulted in

44

numerous flight cancellations. The amount of irregular operations costs is significantly impacted by our decision to compensate impacted passengers for their inconvenience in addition to the ticket price. Unusually high cancellations due to flight crew COVID absences have continued into early 2022.

Depreciation and amortization expense. Depreciation and amortization expense during 2021 increased $4.8 million or 2.7 percent including a $2.9 million increase in amortization of deferred heavy maintenance as compared to 2020 as there was an increase of 5.7 percent in the average number of aircraft in service.

When compared to 2019, depreciation and amortization expense increased 16.2 percent including a 59.7 percent increase in amortization of deferred heavy maintenance as the average number of aircraft in service during the period increased 20.3 percent.

Maintenance and repairs expense. Maintenance and repairs expense during 2021 increased by $42.0 million or 65.8 percent compared to 2020. This was primarily due to a 5.7 percent increase in the average number of aircraft in service and an 18.6 percent increase in utilization year over year as capacity was 33.3 percent lower in 2020 as a result of the pandemic.

As compared to 2019, maintenance and repairs expense increased by $14.2 million or 15.5 percent as the number of aircraft in service increased by 20.3 percent, offset by the effect of a 12.5 percent decrease in utilization year over two year.

Sales and marketing expense. Sales and marketing expense during 2021 increased 67.2 percent compared to 2020. In 2020, advertising spend was intentionally pulled back beginning in March due to the pandemic. There was also an increase in net credit card fees in 2021 as a result of a 75.0 percent increase in passenger revenue year over year.

As compared to 2019, sales and marketing expense decreased by 7.8 percent due to our efforts to more adeptly deploy advertising spend.

Other operating expense. Other expense increased by $4.6 million or 5.8 percent year over year, due to increased flight operations year over year.

Payroll Support Programs grant recognition. We received a total of $203.9 million during 2021 from the U.S. Treasury through the payroll support programs. The direct grants were recognized as a credit to operating expense on our statement of income, over the periods for which the funds were intended to compensate.

During 2020, we received $176.9 million in funds through the payroll support programs. We recognized $152.4 million of the direct grants as an offset to operating expense on our statement of income.

Special charges. Special charges of $14.0 million were recorded within operating expenses during 2021 compared to $306.3 million in 2020. The special charges relate to expenses that were unique and specific to COVID-19. These charges in 2021 include accelerated retirements of two airframes and three engines, acceleration of certain existing stock awards and an impairment loss on a building associated with the Allegiant Nonstop family entertainment line of business. Special charges recorded during 2020 included accelerated retirements of aircraft and airframes, impairment charges primarily in our non-airline subsidiaries, a loss on sale-leaseback transactions we would not likely have transacted absent cash conservation efforts as a result of COVID, salaries and benefits expense, and other various expenses during 2020. See Note 2 of the Notes to Consolidated Financial Statement for further information.

Non-operating special charges. Special charges of $26.6 million were recorded within non-operating expenses during 2020. We did not have any non-operating special charges in 2021.

Income Tax Expense. We recorded a $44.8 million tax expense (22.8 percent effective tax rate) compared to a $176.9 million tax benefit (49.0 percent effective tax rate) during 2021 and 2020 respectively. The 22.8 percent effective tax rate for 2021 differed from the statutory federal income tax rate of 21.0 percent primarily due to state income taxes and the impact of ASU 2016-09 related to share-based payments. The 49.0 percent effective tax rate for 2020 differed from the statutory federal income tax rate of 21.0 percent primarily due to the tax accounting impact of the CARES Act which includes a $98.0 million federal income tax benefit related to the full utilization of 2018 and 2019 net operating losses as well as the ability to carryback the majority of the 2020 net operating loss at a 35.0 percent tax rate applicable in earlier years as well as the remeasurement of deferred taxes and state taxes.

2020 compared to 2019

The comparison of our 2020 results to 2019 results is included in our Annual Report on Form 10-K for the year ended December 31, 2020, under Part II Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations.

LIQUIDITY AND CAPITAL RESOURCES

Current liquidity

Cash, cash equivalents and investment securities (short-term and long-term) increased to $1.2 billion at December 31, 2021, from $685.2 million at December 31, 2020. Investment securities represent highly liquid marketable securities which are available-for-sale.

Restricted cash represents escrowed funds under fixed fee contracts, escrowed project funds and cash collateral against letters of credit required by hotel properties for guaranteed room availability, airports and certain other parties. Under our fixed fee flying contracts, we require our customers to prepay for flights to be provided by us. The prepayments are escrowed until the flight is completed and are recorded as restricted cash with a corresponding amount reflected as air traffic liability.

During 2021, we received a total of $203.9 million in assistance through the payroll support programs.

We suspended share repurchases and our quarterly cash dividend in first quarter 2020, as part of cash conservation efforts in response to the effects of COVID-19 on our business. In connection with our receipt of financial support under the payroll support programs, we agreed not to repurchase shares or pay cash dividends through September 30, 2022.

We believe we have more than adequate liquidity resources through our cash, cash equivalent and short term investment balances, operating cash flows and borrowings, to meet our current contractual obligations. We will continue to consider raising funds through debt financing on an opportunistic basis.

Debt

Our debt and finance lease obligations balance, without reduction for related issuance costs, increased from $1.68 billion as of December 31, 2020 to $1.77 billion as of December 31, 2021. During 2021, we borrowed $384.6 million and we made principal payments of $301.1 million, including $53.9 million on our senior secured revolving credit facility that matured on March 31, 2021 and $79.0 million in prepayments of debt secured by aircraft.

Sources and Uses of Cash

Operating Activities. Operating cash inflows are primarily derived from providing air transportation and related ancillary products and services to customers. During 2021, our operating activities provided $538.2 million of cash compared to $234.6 million during 2020. This change was mostly attributable to a $335.9 million increase in net income.

Investing Activities. Cash used in investing activities was $593.3 million during 2021 compared to $365.7 million in 2020. The change was due to an increase of $111.6 million of purchases of investment securities, net of maturities and a $50 million investment in 2021 in a note receivable to the counterparty in our announced joint venture alliance. In addition, there was $87.6 million related to proceeds from sale-leaseback transactions during 2020 compared to no such transactions in 2021. Purchases of property and equipment increased $25.6 million year over year.

Financing Activities. Cash provided by financing activities for 2021 was $285.5 million, compared to $164.6 million in 2020. The year-over-year change is mostly due to the equity offering completed on May 10, 2021 which resulted in the receipt of $335.1 million in cash. This was offset by the net effect of debt activity, as principal payments and debt issuance costs exceeded debt proceeds by $27.7 million during 2021, compared to $203.0 million of debt proceeds (net of related costs) in excess of principal payments during 2020. Additionally, there were no share repurchases or dividends paid in 2021, where there was $33.8 million and $11.4 million of such activity, respectively, in 2020.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amount of assets and liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of our financial statements based on events and transactions occurring during the periods reported. Note 3 to our Consolidated Financial Statements provides a detailed discussion of our significant accounting policies.

Critical accounting policies are defined as those policies that reflect significant judgments about matters that are inherently uncertain. Our actual results may differ from these estimates under different assumptions or conditions. We believe our critical accounting policies are limited to those described below. 

Affinity Credit Card Program

The Allegiant World Mastercard® is issued by Bank of America through which arrangement points are sold and consideration is received under an agreement which, as amended in September 2020, expires in 2029. Under this arrangement, we identified the following deliverables: travel points to be awarded (the travel component), use of our brand and access to our member lists, and certain other advertising and marketing elements (collectively the marketing component). Each of these deliverables is accounted for separately and allocation of the consideration from the agreement is determined based on the relative selling price of each deliverable. We applied a level of management judgment and estimation in determining the best estimate of selling price for each deliverable by considering multiple inputs and methods including, but not limited to, the redemption value of points awarded, discounted cash flows, brand value, volume discounts, published selling prices, number of points to be awarded and number of points expected to be redeemed.

Revenue from the travel component is deferred based on its relative selling price and is recognized into scheduled service revenue when the points are redeemed by cardholders and transportation is provided. Revenue from the marketing component is considered earned in the period in which points are sold and is therefore recognized into third party products revenue in the same period.

Accounting for Long-Lived Assets

We record impairment losses on long-lived assets used in operations, consisting principally of property and equipment, when events or changes in circumstances indicate, in management’s judgment, that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. In making these determinations, we utilize certain assumptions, including, but not limited to: (i) estimated fair value of the assets; and (ii) estimated future cash flows expected to be generated by those assets which are based on additional assumptions such as (but not limited to) asset utilization, average fare, block hours, fuel costs, length of service the asset will be used in operations, and estimated salvage values.

In estimating the useful lives and residual values of our aircraft, we have primarily relied upon actual experience with the same or similar aircraft types, current and projected future market information, and input from other industry sources. Subsequent revisions to these estimates could be caused by changing market prices of our aircraft, changes in utilization of the aircraft, and other fleet events. To the extent a change in estimate for useful lives or salvage values of our property and equipment occurs, there could be an acceleration of depreciation expense associated with the change in estimate. See Note 3 to the Consolidated Financial Statements for further detail.

Aircraft Maintenance and Repair Costs and Major Maintenance Deferral 

We account for major maintenance costs of Airbus airframes and the related CFM engines using the deferral method. Under this method, the cost of major maintenance events is capitalized and amortized as a component of depreciation and amortization expense over the estimated period until the next scheduled major maintenance event. The timing of the next major maintenance event is estimated based on assumptions including estimated cycles, hours and months, required maintenance intervals, and the age/condition of related parts. These assumptions may change based on forecasted aircraft utilization changes, updates to government regulations, and manufacturer maintenance intervals, as well as unplanned incidents causing damage requiring a major maintenance event prior to a scheduled visit. If the estimated timing of the next maintenance event changes, the related amortization period would also change.

Passenger Revenue

Sales of passenger tickets not yet flown are recorded in air traffic liability. Passenger revenue is recognized when transportation is provided. The air traffic liability primarily includes sales of passenger tickets with scheduled departure dates in the future as well as credit vouchers which can be applied as payment toward the cost of a ticket. Credit vouchers are typically issued as a result of canceled travel prior to the contractual expiration date.

48

We have experienced significant levels of canceled travel, particularly in the early months of the pandemic in 2020. During 2020, we suspended change and cancellation fees. In 2020, we announced that credit vouchers issued as a result of canceled travel beginning in January 2020 would have an extended expiration date of two years from the original booking date. This policy continued for credit vouchers issued through June 30, 2021. Effective July 1, 2021, credit vouchers issued have an expiration date of one year from the original booking date.Credit vouchers represented approximately 22 percent of the air traffic liability as of December 31, 2021. This compares to approximately 72 percent as of December 31, 2020 and approximately 8 percent prior to the onset of the COVID-19 pandemic.

We estimate the amount of credit vouchers not expected to be redeemed prior to their contractual expiration date ("credit voucher breakage") and recognize the associated passenger revenue at the time of issuance. Our credit voucher breakage estimates are primarily based on historical usage data, contract duration and resulting customer behavior. Given the impact of the COVID-19 pandemic on customer behavior and changes made in ticket validity terms, as well as the suspension of change and cancellation fees, our estimates of passenger revenue that will be recognized from the air traffic liability for credit voucher breakage may be adjusted in future periods as we periodically review our estimates based on actual experience to date.

For additional information on our significant accounting policies related to passenger ticket sales, see Note 3 of the Notes to the Consolidated Financial Statements.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

We are subject to certain market risks, including changes in interest rates and commodity prices (specifically, aircraft fuel). The adverse effects of changes in markets could pose potential loss, as discussed below. The sensitivity analysis does not consider the effects that such adverse changes may have on overall economic activity, nor does it consider additional actions we may take to mitigate our exposure to such changes. Actual results may differ.

Aircraft Fuel

Our results of operations can be significantly impacted by changes in the price and availability of aircraft fuel. Aircraft fuel expense during 2021 represented 30.5 percent of our total operating expenses. Increases in fuel prices, or a shortage of supply, could have a material impact on our operations and operating results. Based on our fuel consumption during 2021, a hypothetical ten percent increase in the average price per gallon of fuel would have increased fuel expense by approximately $44.9 million. We have not hedged fuel price risk for many years.

Interest Rates

As of December 31, 2021, we had $927.5 million of variable-rate debt, including current maturities and without reduction of $12.4 million in related costs. A hypothetical 100 basis point change in interest rates would have affected interest expense on variable rate debt by approximately $10.3 million during 2021.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors

Allegiant Travel Company:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Allegiant Travel Company and subsidiaries (the Company) as of December 31, 2021 and 2020, the related consolidated statements of income, comprehensive income, shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2021, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 1, 2022 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Estimated credit vouchers not expected to be redeemed

As discussed in Note 4 to the consolidated financial statements, the Company recorded an air traffic liability of $307.5 million, of which $67.0 million relates to credit vouchers for future travel as of December 31, 2021. In response to the COVID-19 pandemic, the contract duration for credit vouchers issued for canceled travel between January 1, 2020 and June 30, 2021 was extended from one to two years from the original booking date. The air traffic liability as of December 31, 2021 represents the value of credit vouchers for future travel, less an estimate for the amount of credit vouchers that are not expected to be redeemed prior to their contractual expiration date. The amount of such credit vouchers expected to expire unused is estimated based on the Company’s historical usage data for credit vouchers.

We identified the evaluation of certain credit vouchers used to determine the estimated air traffic liability as a critical audit matter. Subjective and challenging auditor judgment was required to evaluate the estimated amount of credit vouchers issued for canceled travel between January 1, 2020 and June 30, 2021 that are expected to expire unused. There is inherent uncertainty associated with management’s assumption of the historical usage data, which may differ from future usage of these credit vouchers.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s air traffic liability process, including controls related to the estimated amount of credit vouchers expected to expire unused. We assessed the

53

reasonableness of the Company’s estimate of credit vouchers issued between January 1, 2020 and June 30, 2021 expected to expire unused by comparing expected future usage to historical usage. We also evaluated the Company’s estimated amount of credit vouchers expected to expire unused by comparing it to our expectation, developed based on actual expirations of these credit vouchers that occurred subsequent to December 31, 2021.

ALLEGIANT TRAVEL COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For the years ended December 31, 2021, 2020 and 2019

Note 1 — Organization and Business of Company

Allegiant Travel Company (the “Company”) is a leisure travel company focused on providing travel services and products to residents of under-served cities in the United States. The Company operates a low-cost, low utilization passenger airline which sells air transportation both on a stand-alone basis and bundled with the sale of ancillary air-related and third party services and products. The Company also provides air transportation under fixed fee flying arrangements, generates other ancillary revenues, and operates non-airline related entities which include the development of Sunseeker Resort and related golf course. Previously, the Company also operated Allegiant Nonstop family entertainment centers and the Teesnap golf course management solution.

Scheduled service and fixed fee air transportation services have similar operating margins, economic characteristics, and production processes (check-in, baggage handling and flight services) which target the same class of customers, and are subject to the same regulatory environment. As a result, the Company believes its airline activities operate under one reportable segment and does not separately track expenses for scheduled service and fixed fee air transportation services. The Company's non-airline related entities represent separate reportable segments and include Sunseeker Resort, and other non-airline activities. Refer to Note 16 for additional information.

60

Note 2 — Impact of the COVID-19 Pandemic

The rapid spread of COVID-19 and the related government restrictions, social distancing measures, and consumer fears have impacted flight loads, resulted in unprecedented cancellations of bookings and substantially reduced demand for new bookings throughout the airline industry. Starting in March 2020, the Company and the airline industry experienced a severe reduction in air travel which continued into 2021 to some extent. Demand in the foreseeable future will continue to be affected by fluctuations in COVID-19 cases, variants, hospitalizations, deaths, treatment efficacy and the availability of vaccines. The Company is continuously reevaluating flight schedules and adjusting capacity based on demand trends.

During 2020 and 2021, Congress enacted various legislation which provided support for the airline industry. This included The Coronavirus Aid, Relief and Economic Security Act (the "CARES Act") enacted in March 2020, the Consolidated Appropriations Act, 2021 enacted in December 2020 (the “Payroll Support Program Extension”) and the American Rescue Plan Act enacted in March 2021) (the “ARPA”). On January 15, 2021, the Company through its airline operating subsidiary Allegiant Air, LLC entered into a Payroll Support Program Extension Agreement (the “PSP2”) with the Treasury and received $91.8 million under the Payroll Support Program Extension.

In April 2021, the Company received $13.8 million in additional funds related to the PSP2 which included a loan of $1.7 million. In consideration for these additional funds, the Company issued additional warrants ( the "PSP2 Warrants") to the Treasury to acquire 924 shares of common stock at a price of $179.23 per share (based on the price of the Company's common stock on the Nasdaq Global Select Market on December 24, 2020).

The funds under PSP2 were used exclusively for wages, salaries and benefits.

In April 2021, the Company through its airline operating subsidiary Allegiant Air, LLC entered into a Payroll Support Program 3 Agreement (the "PSP3") with the Treasury under the ARPA and received a total of $98.4 million. The funds were used exclusively for wages, salaries and benefits.

As of December 31, 2021, all Payroll Support Program funds have been fully utilized.

Note 3 — Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements include the accounts of Allegiant Travel Company and its majority-owned operating subsidiaries. The Company's investments in unconsolidated affiliates, which are 50 percent or less owned, are accounted for under the equity or cost method. All intercompany balances and transactions have been eliminated.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from these estimates.

Cash and Cash Equivalents

Cash and cash equivalents include investments and interest bearing instruments with original maturities of three months or less. Such investments are carried at cost which approximates fair value.

Restricted Cash

Restricted cash represents escrowed funds under fixed fee contracts, and cash collateral held against letters of credit required by hotel properties for guaranteed room availability, airports and certain other parties.

Accounts Receivable

Accounts receivable are carried at face amount which approximates fair value. In addition to income tax receivables, the accounts receivable consist primarily of amounts due from credit card companies associated with the sale of tickets for future travel. These receivables are short-term and generally settle within a few days of sale. There are also receivables related to commission amounts due from Enterprise Holdings Inc. based on terms in the rental car provider agreement and amounts due related to fixed fee charter agreements. If deemed necessary, the Company records charges to its allowance for doubtful accounts for amounts not expected to be collected, for which the balance was immaterial for all years presented.

Short-term and Long-term Investments

The Company’s investments in marketable securities are classified as available-for-sale and are reported at fair value with the net unrealized gain or (loss) reported as a component of accumulated other comprehensive income (loss) in shareholders’ equity. For investments in an unrealized loss position, the Company determines whether a credit loss exists by considering information about the collectability of the instrument and current market conditions. There have been no credit losses in the years presented. Investment securities with original maturities of three months or less are classified as cash equivalents. Investment securities with original maturities greater than three months are classified as either short-term investments or long-term investments based on the maturity date in relation to the balance sheet date. Short-term investments have a maturity date less than or equal to one year from the balance sheet date, and long-term investments have a maturity date greater than one year from the balance sheet date. 

The amortized cost of investment securities sold is determined by the specific identification method with any realized gains or losses reflected in other (income) expense. The Company had minimal realized losses during the years ended December 31, 2021, 2020, and 2019. The Company believes unrealized losses related to debt securities are not other-than-temporary and does not intend to sell these securities prior to amortized cost recoverability.

The Company attempts to minimize its concentration risk with regard to its cash, cash equivalents, and investment portfolio. This is accomplished by diversifying and limiting amounts among different counterparties, the type of investment, and the amount invested in any individual security, commercial paper, or money market fund.

Expendable Parts, Supplies and Fuel, Net

Expendable parts, supplies and fuel inventories are valued at cost using the first-in, first-out method. Such inventories are charged to expense as they are used in operations. An obsolescence allowance for expendable parts and supplies is based on salvage values and the average remaining useful life of the Airbus fleet. The obsolescence allowance for expendable parts and supplies was $6.0 million and $4.3 million at December 31, 2021 and 2020, respectively. Rotable aircraft parts inventories are included in property and equipment.

Deposits and Other Assets

Deposits and Other Assets consist primarily of airport deposits, aircraft purchase deposits, deposits as required by the construction loan agreement and a note receivable to the counter-party in the Company’s joint venture alliance. The Company also had outstanding receivables from third parties as of December 31, 2021 and 2020, of which $12.4 million and $10.9 million respectively, was due more than one year after the balance sheet date.

62

Operating Lease Right-of-Use Asset and Liability

The Company determines if an arrangement is a lease at inception and has lease agreements for aircraft, office facilities, office equipment, certain airport and terminal facilities, and other space and assets with non-cancelable lease terms. Certain real estate and property leases, aircraft leases, and various other operating leases are measured on the balance sheet with a lease liability and right-of-use ("ROU") asset. Airport terminal leases mostly include variable lease payments outside of those based on a fixed index, and are therefore excluded from consideration.

ROU assets represent the Company's right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make scheduled lease payments. ROU assets and liabilities are recognized on the lease commencement date based on the present value of lease payments over the lease term. The present value of lease payments is calculated using an estimated incremental borrowing rate at lease commencement, which takes into consideration recent debt issuances as well as other applicable market data available.

Lease payments include fixed payments, variable payments based on an index or rate, reasonably certain purchase options, termination penalties, and others as required by the Accounting Standards (ASU) 2016-02, Leases (Topic 842). Lease payments do not include variable lease payments other than those that depend on an index or rate, any guarantee by the lessee of the lessor’s debt, or any amount allocated to non-lease components.

Lease terms include options to extend when it is reasonably certain that the option will be exercised. Leases with a term of 12 months or less are not recorded on the balance sheet. Additionally, lease and non-lease components are accounted for as a single lease component for real estate agreements.

Property and Equipment

Property and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives less any estimated salvage value. Property under finance leases and related obligations are initially recorded at an amount equal to the present value of future minimum lease payments computed on the basis of the Company’s incremental borrowing rate, and depreciation is recorded on a straight-line basis and is included within depreciation and amortization expense. The estimated useful lives of the principal asset classes are shown below.

Aircraft, engines and related rotable parts	10-25 years
Buildings and leasehold improvements	10-25 years
Equipment	3-10 years
Computer hardware and software	3-10 years

In estimating the useful lives and residual values of aircraft, the Company primarily relies upon actual experience with the same or similar aircraft types, current and projected future market information, and input from other industry sources. Subsequent revisions to these estimates could be caused by changing market prices of the Company’s aircraft, changes in utilization of the aircraft, and other fleet events. Changes in the estimate for useful lives or residual values of the Company’s property and equipment could result in changes in depreciation expense.

Interest is capitalized using the Company’s weighted average borrowing rate and depreciated over the estimated useful life of the related asset(s) acquired/developed. Capitalized interest for the years ended December 31, 2021, 2020 and 2019 was $0.2 million, $4.1 million and $4.5 million, respectively.

Software Capitalization

The Company capitalizes certain internal and external costs related to the acquisition and development of computer software during the application development stage of projects. The Company amortizes these capitalized costs using the straight-line method over the estimated useful life of the software, which typically ranges from three to ten years. The Company had unamortized computer software development costs of $43.3 million and $42.3 million as of December 31, 2021 and 2020, respectively. Amortization expense related to computer software was $10.6 million, $9.6 million and $12.2 million for the years ended December 31, 2021, 2020 and 2019 respectively. Costs incurred during the preliminary and post-implementation stages are expensed as incurred.

Aircraft Maintenance and Repair Costs

The Company accounts for all non-major maintenance and repair costs incurred for its Airbus fleet under the direct expense method. Under this method, maintenance and repair costs for aircraft are charged to operating expenses as incurred. Maintenance and repair costs includes all parts, materials, and line maintenance activities required to maintain the Company's fleet.

63

The Company accounts for major maintenance costs of its Airbus airframes and the related CFM engines using the deferral method. Under this method, the Company capitalizes the cost of major maintenance events, which are amortized as a component of depreciation and amortization expense, over the estimated period until the next scheduled major maintenance event. During 2021 and 2020, the Company capitalized $23.3 million and $12.8 million of major maintenance costs for engines with associated amortization expense of $21.0 million and $17.6 million respectively. During 2021 and 2020, the Company capitalized $39.0 million and $22.6 million of major maintenance costs for airframes. Amortization expense related to major maintenance costs was $21.1 million, $19.9 million and $14.9 million for the years ended December 31, 2021, 2020 and 2019 respectively.

Measurement of Impairment of Long-Lived Assets

The Company records impairment losses on long-lived assets used in operations, consisting principally of property and equipment, when events or changes in circumstances indicate, in management’s judgment, that the assets might be impaired, and the undiscounted future cash flows estimated to be generated by those assets are less than the carrying amount of those assets. In making these determinations, the Company utilizes certain assumptions, including, but not limited to: (i) estimated fair value of the assets; and (ii) estimated future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, length of service for which the asset will be used in operations, and estimated salvage values.

For the year ended December 31, 2019, the Company did not incur any impairment losses.

For the year ended December 31, 2020, the Company recorded a $161.6 million impairment as a result of COVID-19.

For the year ended December 31, 2021, the Company recorded a $0.5 million impairment loss on a building in Chesterfield, Missouri associated with the Allegiant Nonstop family entertainment line of business.

Revenue Recognition

Passenger revenue

Passenger revenue includes scheduled service revenue, ancillary air-related charges, and travel point redemptions from the co-branded Allegiant World Mastercard® credit card and the Company's non-card loyalty program.

Scheduled service revenue consists of ticket revenue generated from nonstop flights in the Company’s route network, recognized either when the transportation is provided or when ticket voucher breakage occurs. Nonrefundable scheduled itineraries expire on the date of the intended flight, unless the date is extended by notification from the customer in advance. Itineraries sold for transportation not yet used, as well as unexpired credits, are included in air traffic liability.

Ancillary air-related charges include various services and products related to the flight such as baggage fees, the use of the Company’s website to purchase scheduled service transportation, advance seat assignments, and other services which are not included in the base ticket price. Revenues from air-related charges are recognized when the transportation is provided. If a customer cancels a flight, a voucher may be issued for a future flight, at which time the associated revenue is recognized upon completion of the future flight. Additionally, the Company estimates the value of vouchers that will expire unused and recognizes such revenue at the time of issuance.

Various taxes and fees, assessed on the sale of tickets to customers, are collected by the Company serving as an agent, and remitted to taxing authorities. These taxes and fees are not included as revenue in the Company’s consolidated statements of income and are recorded as a liability until remitted to the appropriate taxing authority.

Revenue from travel point redemptions from the co-branded credit card and the Loyalty program are described in the Affinity Credit Card Program and Allways Rewards Loyalty Program sections below.

Third party products revenue

Ancillary third party products revenue is generated from the sale of hotel rooms, rental cars and ticket attractions, as well as marketing revenue associated with the co-branded credit card. Revenue from the sale of third party products is recognized at the time the product is utilized, such as the time a purchased hotel room is occupied. Revenue from the sale of third party products is recorded net of amounts paid to wholesale providers, travel agent commissions, and transaction costs.

Pursuant to the co-brand arrangement with Bank of America, the Company has various performance obligations which are collectively referred to as the marketing component. These obligations consist of use of the Company’s brand and access to its member lists, and certain other advertising and marketing elements. The marketing component is recorded as third party products revenue in the period in which points are awarded to the credit card holders.

Fixed fee contract revenue

64

Fixed fee contract revenue consists of agreements to provide charter service on a year-round and ad hoc basis. Fixed fee contract revenue is recognized when the transportation is provided.

Other revenue

Other revenue is generated from non-airline activities as well as leasing aircraft and engines. Lease revenue is recognized ratably over the lease term.

Affinity Credit Card Program

The Allegiant World Mastercard® is issued by Bank of America through which arrangement points are sold and consideration is received under an agreement that expires in 2029. Under this arrangement, the Company identified the following deliverables: travel points to be awarded (the travel component), use of the Company’s brand and access to its member lists, and certain other advertising and marketing elements (collectively the marketing component). Each of these deliverables is accounted for separately and allocation of the consideration from the agreement is determined based on the relative selling price of each deliverable. The Company applied a level of management judgment and estimation in determining the best estimate of selling price for each deliverable by considering multiple inputs and methods including, but not limited to, the redemption value of points awarded, discounted cash flows, brand value, volume discounts, published selling prices, number of points to be awarded and number of points expected to be redeemed.

Revenue from the travel component is deferred based on its relative selling price and is recognized into passenger revenue when the points are redeemed by cardholders and transportation is provided. Revenue from the marketing component is considered earned in the period in which points are sold and is therefore recognized into third party products revenue in the same period.

Allways Rewards Loyalty Program

Allegiant’s Allways Rewards Loyalty Program enables program Members to earn points for every dollar they spend on the Company’s website. Under the program, which launched in August 2021, Members continue to accumulate points until the time they decide to redeem them. In addition to opportunities to redeem points for flights, lodging and rental cars, the program leverages Allegiant's partnerships to offer additional rewards to Members, including sports and live music event tickets and exclusive experiences. Members can also earn points by using their Allegiant World Mastercard®.

Under Allways Rewards, Members receive one point for every dollar spent at Allegiant.com, and two points per $1 for spending over $500 (excluding taxes and fees). The Company utilizes the deferred revenue method of accounting for points earned through the program based on the stand alone selling price and revenue is recognized when points are redeemed and the underlying service has been provided.

Advertising Costs

Advertising costs are charged to expense in the period incurred. Advertising expense was $31.3 million, $12.4 million and $29.1 million for the years ended December 31, 2021, 2020 and 2019, respectively. In 2019, the Company entered into a naming rights agreement with the Raiders of the National Football League for the professional football stadium in Las Vegas which opened in 2020. Prepayments and other associated advertising expenses began in mid-2020 and will continue through the term of this agreement.

Earnings per Share

Basic and diluted earnings per share are computed pursuant to the two-class method as opposed to the treasury method. Under the two-class method, the Company attributes net income to two classes, common stock and unvested restricted stock awards. Unvested restricted stock awards granted to employees under the Company’s Long-Term Incentive Plan are considered participating securities because they receive non-forfeitable rights to cash dividends at the same rate as common stock.

Diluted net income per share is calculated using the more dilutive of two methods. Under both methods, the exercise of employee stock options is assumed using the treasury stock method. The assumption of vesting of restricted stock, however, differs as described below:

1.Assume vesting of restricted stock using the treasury stock method.

2.Assume unvested restricted stock awards are not vested, and allocate earnings to common shares and unvested restricted stock awards using the two-class method.

65

For the years ended December 31, 2021 and 2019, the second method above was used in the computation because it was more dilutive than the first method. Given the loss position in 2020, both methods yield the same result. The following table sets forth the computation of net income (loss) per share on a basic and diluted basis for the periods indicated: 

	Year ended December 31,
(in thousands, except per share data)	2021		2020		2019
Basic:
Net income (loss)	$	151,853	$	(184,093)	$	232,117
Less income allocated to participating securities	(2,218)		(236)		(3,413)
Net income (loss) attributable to common stock	$	149,635	$	(184,329)	$	228,704
Earnings (loss) per share, basic	$	8.69	$	(11.53)	$	14.27
Weighted-average shares outstanding	17,212		15,992		16,027
Diluted:

Less income allocated to participating securities	(2,215)		(236)		(3,410)
Net income (loss) attributable to common stock	$	149,638	$	(184,329)	$	228,707
Earnings (loss) per share, diluted	$	8.68	$	(11.53)	$	14.26
Weighted-average shares outstanding	17,212		15,992		16,027
Dilutive effect of stock options and restricted stock	145		—		51
Adjusted weighted-average shares outstanding under treasury stock method	17,357		15,992		16,078
Participating securities excluded under two-class method	(126)		—		(37)
Adjusted weighted-average shares outstanding under two-class method	17,231		15,992		16,041

Stock awards outstanding of 815, 24,004, and 19,928 shares (not in thousands) as of December 31, 2021, 2020, and 2019, respectively, were excluded from the computation of diluted earnings per share as they were antidilutive.

Share-Based Compensation

The Company accounts for share-based compensation in accordance with accounting standards which require the compensation cost related to share-based payment transactions be recognized in the Company’s consolidated statements of income. The share-based cost is measured based on grant date fair value. The Company’s share-based employee compensation plan is more fully discussed in Note 13.

Income Taxes

The Company recognizes deferred income taxes based on the asset and liability method required by accounting standards. Deferred tax assets and liabilities are determined based on the timing differences between book basis for financial reporting purposes and tax basis of the asset and liability and measured using the enacted tax rates and provisions of the enacted tax law. A valuation allowance for deferred tax assets is provided if it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company determines the net non-current deferred tax assets or liabilities separately for federal, state, foreign and other local jurisdictions.

The Company’s income tax returns are subject to examination by the Internal Revenue Service (“IRS”) and other tax authorities in the jurisdictions where the Company operates. The Company assesses potentially unfavorable outcomes of such examinations based on the criteria set forth in uncertain tax position accounting standards. The accounting standards prescribe a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements.

Accounting standards for income taxes utilize a two-step approach for evaluating tax positions. Recognition (Step I) occurs when the Company concludes that a tax position, based on its technical merits, is more likely than not to be sustained upon examination. Measurement (Step II) is only addressed if the position is deemed to be more likely than not to be sustained. Under Step II, the tax benefit is measured as the largest amount of benefit that is greater than 50 percent likely of being realized upon settlement.

The tax positions failing to qualify for initial recognition are recognized in the first subsequent interim period they meet the “more likely than not” standard. If it is subsequently determined that a previously recognized tax position no longer meets the “more likely than not” standard, it is required that the tax position be derecognized. As applicable, the Company will recognize accrued penalties and interest related to unrecognized tax benefits in the provision for income taxes.

Recent Accounting Pronouncements

On June 16, 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments. The standard requires the use of an “expected loss” model on certain types of financial instruments. The standard also amends the impairment model for available-for-sale debt securities and requires estimated credit losses to be recorded as allowances instead of reductions to amortized cost of the securities. The Company adopted this accounting standard prospectively as of January 1, 2020, and it did not have a significant impact on its consolidated financial statements

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This standard is intended to simplify various aspects related to accounting for income taxes and is effective for fiscal years beginning after December 15, 2020, including interim periods therein, and early adoption is permitted. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application of Topic 740. The Company adopted ASU 2019-12 in the first quarter of 2021 and its adoption did not have a material effect on the Company's consolidated financial statements.

On November 17, 2021, the Financial Accounting Standards Board (the "FASB") issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. The new standard increases transparency of government assistance by focusing on the types of assistance given, an entity's accounting for the assistance, and the effect of the assistance on the entity's financial statements to allow for more comparable information for investors and other financial statement users. This standard is effective for all entities under the scope for financial statements issued for annual periods beginning after December 15, 2021, but early adoption is permitted. The Company adopted the standard early as of January 1, 2021. See Note 2 for further information on the Company's treatment of government assistance received.

Note 4 — Revenue Recognition

Passenger revenue

Passenger revenue is the most significant category in our reported operating revenues, as outlined below:

	Year Ended December 31,
(in thousands)	2021		2020		2019
Scheduled service	$	769,371	$	435,668	$	897,631
Ancillary air-related charges	788,064		453,545		770,206
Loyalty redemptions	21,001		12,974		15,118
Total passenger revenue	$	1,578,436	$	902,187	$	1,682,955

Sales of passenger tickets not yet flown are recorded in air traffic liability. Passenger revenue is recognized when transportation is provided. As of December 31, 2021, the air traffic liability balance was $307.5 million, of which approximately $240.5 million was related to forward bookings, with the remaining $67.0 million related to credit vouchers for future travel.

The normal contract term of passenger tickets is 12 months and passenger revenue associated with future travel will principally be recognized within this time frame. Of the $307.5 million that was recorded in the air traffic liability balance at December 31, 2020, 88.0 percent was recognized into passenger revenue during the 12 months ended December 31, 2021.

In 2020, the Company announced that credit vouchers issued for canceled travel beginning in January 2020 would have an extended expiration date of two years from the original booking date. This policy continued for credit vouchers issued through June 30, 2021. Estimates of passenger revenue to be recognized from air traffic liability for credit voucher breakage may be subject to variability and differ from historical experience due to the change in contract duration and uncertainty regarding demand for future air travel. Effective July 1, 2021, vouchers issued have an expiration date of one year from the original booking date.

The Company periodically evaluates the estimated amount of credit vouchers expected to expire unused and any adjustment is removed from air traffic liability and included in passenger revenue in the period in which the evaluation is complete.

Loyalty redemptions

In relation to the travel component of the co-branded credit card contract with Bank of America, the Company has a performance obligation to provide cardholders with points to be used for future travel award redemptions. Therefore, consideration received from Bank of America related to the travel component is deferred based on its relative selling price and is recognized into passenger revenue when the points are redeemed and the transportation is provided.

The following table presents the activity of the co-brand point liability as of the dates indicated:

	Year Ended December 31,
(in thousands)	2021		2020
Balance at January 1	$	21,841	$	15,613
Points awarded	39,650		19,202
Points redeemed	(21,001)		(12,974)
Balance at December 31	$	40,490	$	21,841

As of December 31, 2021 and 2020, $17.8 million and $10.9 million, respectively, of the current points liability is reflected in accrued liabilities and represents the current estimate of revenue to be recognized in the next 12 months based on historical trends, with the remaining balance reflected in other noncurrent liabilities and expected to be recognized into revenue in periods thereafter.

Term Loan and Senior Secured Notes

In February 2019, the Company entered into a Credit and Guaranty Agreement (the “Term Loan”) to borrow $450.0 million, guaranteed by all of the Company's subsidiaries, excluding Sunseeker Resorts Inc. and its subsidiaries, and other insignificant subsidiaries (the "Term Loan Guarantors"). In February 2020, the Company entered into an amendment to the Term Loan under which the interest rate was reduced by 150 basis points, and the principal amount of the debt was increased by a net amount of $100.0 million to $545.5 million. Quarterly principal payments increased under the amendment, but the remaining provisions were substantially unchanged, including the maturity date. The Term Loan is secured by substantially all property and assets of the Company and the Term Loan Guarantors, excluding aircraft and aircraft engines, and excluding certain other assets. The Term Loan bears interest based on LIBOR with a zero percent floor and provides for quarterly interest payments along with quarterly principal payments of $1.4 million through February 2024, at which time the Term Loan is due. The Term Loan may be prepaid at any time without penalty.

In October 2020, the Company closed on the private offering of $150.0 million principal amount of 8.5 percent Senior Secured Notes due 2024 (the "Senior Secured Notes"). The Senior Secured Notes and related guarantees are secured by first priority security interests in the same collateral package as securing the Term Loan and the debt is subject to an Intercreditor Agreement with the collateral agent for the Term Loan. The guarantors of the Notes include all significant subsidiaries other than Sunseeker Resorts, Inc. and its subsidiaries.

Consolidated Variable Interest Entities

The Company evaluates ownership, contractual lease arrangements and other interests in entities to determine if they are variable interest entities ("VIEs") based on the nature and extent of those interests. The Company consolidates a VIE when, among other criteria, it has the power to direct the activities that most significantly impact the VIE’s economic performance as well as the obligation to absorb losses or the right to receive benefits of the VIE, thus making the Company the primary beneficiary of the VIE.

In October 2019, the Company, through a wholly owned subsidiary, entered into agreements with a trust to borrow $23.5 million secured by one Airbus A320 series aircraft. The trust was funded on inception. The borrowing bears interest at a blended rate of

71

3.2 percent and is payable in monthly installments through October 2024, at which time the Company will have a purchase option at a fixed amount. As this transaction is a common control transaction, the Company, as the primary beneficiary, has measured and recorded the assets and liabilities at their carrying values, which were $18.6 million and $23.5 million, respectively, at the time of borrowing.

In March 2019, the Company, through a wholly owned subsidiary, entered into agreements with a trust to borrow $44.0 million secured by one Airbus A320 series aircraft. The trust was funded on inception. The borrowing bears interest at a blended rate of 3.8 percent and is payable in quarterly installments through April 2029, at which time the Company will have a purchase option at a fixed amount. As this transaction is a common control transaction, the Company, as the primary beneficiary, has measured and recorded the assets and liabilities at their carrying values, which were $38.5 million and $44.0 million, respectively, at the time of borrowing.

In September 2018, the Company, through a wholly owned subsidiary, entered into agreements with a trust to borrow $44.0 million secured by one Airbus A320 series aircraft. The trust was funded on inception. The borrowing bears interest at a blended rate of 4.0 percent and is payable in quarterly installments through September 2028, at which time the Company will have a purchase option at a fixed amount. As this transaction is a common control transaction, the Company, as the primary beneficiary, has measured and recorded the assets and liabilities at their carrying values, which were $37.8 million and $44.0 million, respectively, at the time of borrowing.

Payroll Support Program Loans

In 2020 and 2021, the Company entered into low-interest rate, senior unsecured term promissory notes (the "PSP Notes") with the Treasury under the Payroll Support Programs. The Notes mature in full after ten years, and bear interest at a rate of 1.0 percent per annum for the first five years and, thereafter, at the secured overnight financing rate (SOFR) plus 2 percent. The PSP Notes are prepayable at any time at par, without penalty.

As of December 31, 2021, the Company received $24.7 million in funds under the PSP Notes, which is recorded within noncurrent debt on the balance sheet.

In connection with the Payroll Support Programs, the Company is required to comply with the relevant provisions of the CARES Act, the Payroll Support Program Extension and ARPA, including those prohibiting the repurchase of common stock and the payment of common stock dividends through September 30, 2022, as well as those restricting the payment of certain executive compensation for periods through March 31, 2023.

Senior Secured Revolving Credit Facility

The senior secured revolving credit facility under which the Company was able to borrow up to $81.0 million matured on March 31, 2021 and the outstanding balance of $46.5 million was paid at that time

In March 2021, the Company entered into a new revolving credit facility under which it is entitled to borrow up to $50.0 million. The facility has a term of 24 months and the borrowing ability is based on the value of the Airbus A320 series aircraft placed into the collateral pool. The notes for amounts borrowed under the facility bear interest at a floating rate based on LIBOR and are due in March 2023. As of December 31, 2021, no aircraft collateral had been added to the collateral pool and the facility was undrawn.

Other Secured Debt

In September 2020, the Company borrowed $84.0 million under a loan agreement secured by aircraft and spare engines. The note bears interest at a fixed rate, payable in monthly installments maturing in September 2025 and September 2026 for the spare engines and aircraft, respectively.

In April 2020, the Company borrowed $31.0 million under a loan agreement secured by two aircraft. The note bears interest at a fixed rate, payable in quarterly installments with a maturity date in April 2028.

Construction Loan Agreement

In October 2021, Sunseeker Florida, Inc. (“SFI”), a wholly-owned subsidiary of the Company, entered into a Credit Agreement pursuant to which SFI may borrow up to $350.0 million funded by one or more entities directly or indirectly managed by Castlelake, L.P.(“Lender”) to fund the remaining construction of the initial phases of Sunseeker Resort at Charlotte Harbor (the "Resort"). The Loan is secured by the Resort. All of the shares in SFI are also pledged to secure the Loan. The Loan bears interest at 5.75 percent per annum payable semi-annually, provides for semi-annual principal payments of $26.0 million beginning in 2025 and matures in October 2028. The Credit Agreement includes covenants similar to the covenants in the Company’s Term Loan. To support the credit, the Company has guaranteed the full amount of the debt, has agreed to guarantee completion of the Project in accordance with approved plans and specifications and made a $30 million deposit into a construction disbursement account. As of December 31, 2021, $175.0 million has been advanced.

Sale-Leaseback Transactions

In March 2021, the Company entered into a sale-leaseback transaction involving three aircraft and generating $105.0 million of proceeds. The lease was classified as a finance lease and as a result, the transaction did not qualify as a sale. The aircraft were not removed from property and equipment in the Company's balance sheet and the Company recorded a financial liability in the amount of $105.0 million. The proceeds from this transaction are treated as cash inflows from finance lease obligations and reported in financing activities on the statement of cash flows.

During the year ended December 31, 2020, the Company entered into sale-leaseback transactions involving eight total aircraft. The transactions qualified as sales, and generated $87.6 million of proceeds. As a result of the sales, the aircraft were removed from property and equipment in the Company's balance sheet, resulting in a $53.2 million loss on the sales. The loss is reflected within operating special charges on the statement of income since the Company would not likely have completed the transactions absent cash conservation efforts as a result of COVID-19. The leased aircraft were subsequently recorded within operating lease right-of-use assets, with the related lease liabilities recorded within current and noncurrent operating lease liabilities on the balance sheet. The proceeds from the sales of aircraft in these transactions are treated as cash inflows from investing activities on the statement of cash flows.

Note 9 — Shareholders’ Equity

The Company is authorized by its Board of Directors to acquire the Company’s stock through open market purchases under its share repurchase program. As repurchase authority is exhausted, the Board of Directors has, to date, authorized additional expenditures for share repurchases. The Company suspended stock repurchases upon the onset of the pandemic and as part of accepting benefits from the Treasury under the Payroll Support Programs, the Company has agreed not to repurchase stock through September 30, 2022.

Share repurchases consisted of the following during the periods indicated:

Note 10 — Fair Value Measurements

Investments

The Company measures certain financial assets and liabilities at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Accounting standards pertaining to fair value measurements establish a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

    Level 1 - Defined as observable inputs such as quoted prices in active markets for identical assets or liabilities

Level 2 - Defined as inputs other than Level 1 inputs that are either directly or indirectly observable

Level 3 - Defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions

The Company uses the market approach valuation technique to determine fair value for investment securities. The assets classified as Level 1 consist of money market funds for which original cost approximates fair value. The assets classified as Level 2 consist of commercial paper, municipal debt securities, federal agency debt securities and corporate debt securities, which are valued using quoted market prices or alternative pricing sources including transactions involving identical or comparable assets and models utilizing market observable inputs. The Company has no investment securities classified as Level 3.

For those assets classified as Level 2 that are not in active markets, the Company obtains fair value from pricing sources using quoted market prices for identical or comparable instruments, and uses pricing models which include all significant observable inputs: maturity dates, issue dates, settlement dates, benchmark yields, reported trades, broker-dealer quotes, issue spreads, benchmark securities, bids, offers and other market related data. These inputs are observable or can be derived from, or corroborated by, observable market data for substantially the full term of the asset.

Financial instruments measured at fair value on a recurring basis:

There were no significant transfers between Level 1 and Level 2 assets for the years ended December 31, 2021 or 2020.

Long-term Debt

None of the Company's long-term debt is publicly traded. The Company has determined the estimated fair value of all of this debt to be Level 3, as certain inputs used to determine the fair value of these agreements are unobservable and, therefore, could be sensitive to changes in inputs.The Company utilizes the discounted cash flow method to estimate the fair value of Level 3 debt.

Carrying value and estimated fair value of long-term debt, including current maturities and without reduction for related costs:

	As of December 31, 2021				As of December 31, 2020

Non-publicly held debt	$	1,447,462	$	1,261,170	$	1,555,637	$	1,191,008	3

Other

Due to the short term nature, carrying amounts of cash, cash equivalents, restricted cash, accounts receivable and accounts payable approximate fair value.

Note 13 — Employee Benefit Plans

401(k) Plan

The Company has a defined contribution plan covering all eligible employees. Under the plan, employees may contribute up to 90 percent of their eligible annual compensation with the Company making matching contributions on employee deferrals of up to 5 percent of eligible employee wages. The matching contributions on pilot deferrals is 200 percent for the first 5 percent of eligible wages resulting from the pilot collective bargaining agreement.

The Company recognized expense under this plan of $21.4 million, $18.6 million, and $19.0 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Share-based employee compensation

The Company reserved 2,000,000 shares of common stock for the Company to grant stock options, restricted stock, cash-settled stock appreciation rights ("SARs") and other stock-based awards to certain officers, directors and employees of the Company under the 2016 Long-Term Incentive Plan (the "2016 Plan"). The 2016 Plan is administered by the Company’s compensation committee of the Board of Directors.

Employee Stock Purchase Plan

The Company reserved 1,000,000 shares of common stock for employee purchases under the 2014 Employee Stock Purchase Plan ("ESPP"). Shares are purchased semi-annually, at a discount, based on the market value at period-end. Employees may contribute up to 25 percent of their base pay per offering period, not to exceed $25,000 each calendar year, for the purchase of common stock. The ESPP is a compensatory plan under applicable accounting guidance and results in the recognition of compensation expense.

The following table provides information about the Company’s ESPP activity during 2021, 2020, and 2019:

	Total number of shares purchased in year	Average price paid per share		Weighted-average fair value of discount under the ESPP (1)
As of December 31, 2019	38,464	$	133.54	$	23.51
As of December 31, 2020	56,866	$	90.63	$	14.10
As of December 31, 2021	39,760	$	174.68	$	30.00

(1) The weighted-average fair value of the discount under the ESPP granted is equal to a percentage discount from the market value of the common stock at the end of each semi-annual purchase period. 15 percent is the maximum allowable discount under the ESPP.

Compensation expense

For the years ended December 31, 2021, 2020 and 2019, the Company recorded compensation expense of $17.2 million, $20.1 million and $19.2 million, respectively, related to restricted stock, stock options, cash-settled SARs and the ESPP. Forfeiture rates are estimated at the time of grant based on historical actuals for similar grants, and are matched to actuals over the vesting period.

The unrecognized compensation cost was $23.3 million as of December 31, 2021 for unvested restricted stock expected to be recognized over a weighted-average period of 2.22 years. As of December 31, 2021, there was no unrecognized compensation cost for either cash-settled SARs or stock options.

Restricted stock awards

The closing price of the Company's stock on the date of grant is used as the fair value for the issuance of restricted stock. A summary of the status of non-vested restricted stock grants during the years ended December 31, 2021, 2020 and 2019 is presented below:

	Shares	Weighted Average Grant Date Fair Value Per Share

Note 16 — Segments

Operating segments are components of a company for which separate financial and operating information is regularly evaluated and reported to the Chief Operating Decision Maker ("CODM"), and is used to allocate resources and analyze performance. The Company's CODM is the executive leadership team, which reviews information about the Company's two operating segments: Airline and Sunseeker Resort.

Airline Segment

The Airline segment operates as a single business unit and includes all scheduled service air transportation, ancillary air-related products and services, third party products and services, fixed fee contract air transportation and other airline-related revenue. The CODM evaluation includes, but is not limited to, route and flight profitability data, ancillary and third party product and service offering statistics, and fixed fee contract information when making resource allocation decisions with the goal of optimizing consolidated financial results.

Sunseeker Resort Segment

The Sunseeker Resort segment represents activity related to the development and construction of Sunseeker Resort in Southwest Florida, as well as the operation of Kingsway Golf Course. Plans for the resort include a 500-room hotel and two towers offering an estimated 180 one, two and three-bedroom suites, bar and restaurant options, and other amenities. The golf course is a short drive from the resort site and is considered, from a planning and strategic perspective, to be an additional resort amenity. The construction of Sunseeker Resort is an extension of the Company's leisure travel focus and it is expected that many customers flying to Southwest Florida on Allegiant will elect to stay at this resort and enjoy its amenities.

Other non-Airline Segment

The other non-airline segment includes the Teesnap golf course management solution and Allegiant Nonstop family entertainment centers. Allegiant Nonstop family entertainment centers featured games, attractions, and food facilities.

Due to the impacts of COVID-19, the Company permanently closed the Allegiant Nonstop locations in Warren, MI, Clearfield, Utah, and the Allegiant Nonstop location in West Jordan, Utah, which was being developed.

In April 2021, the Company closed on a transaction to sell 85 percent of Teesnap.

Item 9A.  Controls and Procedures

Evaluation of disclosure controls and procedures. As of the end of the period covered by this report, under the supervision and with the participation of our management, including our CEO and chief financial officer (“CFO”), we evaluated the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the “Exchange Act”). Based on that evaluation, management, including our CEO and CFO, has concluded that our disclosure controls and procedures are designed, and are effective, to give reasonable assurance that the information we are required to disclose is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to the Company’s management, including the CEO and the CFO, as appropriate to allow timely decisions regarding required disclosure.

Changes in internal controls. There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during the fourth quarter of our year ended December 31, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting. Management, under the supervision of the CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2021. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) Internal Control - Integrated Framework (2013 Framework). Based on the assessment, management has concluded that, as of December 31, 2021, our internal control over financial reporting was effective based on those criteria.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. As such, even those systems determined to be effective can provide only reasonable assurance of achieving their control objectives.

We intend to review and evaluate the design and effectiveness of our disclosure controls and procedures and internal control over financial reporting on a regular basis, to improve these controls and procedures over time, and to correct any deficiencies that may be discovered. Future events affecting our business may cause us to modify our controls and procedures.

Our independent registered public accounting firm has issued an attestation report regarding its assessment of the effectiveness of our internal control over financial reporting as of December 31, 2021.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors

Allegiant Travel Company:

Opinion on Internal Control Over Financial Reporting

We have audited Allegiant Travel Company and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2021 and 2020, the related consolidated statements of income, comprehensive income, shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2021, and the related notes (collectively, the consolidated financial statements), and our report dated March 1, 2022 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
