Future Outlook

The proposed acquisition of Sun Country Airlines is anticipated to close in the second half of 2026, expected to broaden the network and improve capacity flexibility. The company plans to continue leveraging higher aircraft utilization during peak demand periods in 2026, though limited ASM growth is expected to lead to an increase in CASM-ex during the year. Projected fleet growth after 2026 is expected to provide additional flexibility for network expansion. The next pilot contract is anticipated to reflect significantly higher industry-competitive rates. The company expects to complete the replacement of its flight and crew management systems with a next-generation platform powered by CAE and the redevelopment of certain internal-use software by the fourth quarter of 2026. The combined entity with Sun Country will operate approximately 195 aircraft, enhancing scale, fuel efficiency, and capacity. The company is also assessing sustainable aviation fuels as part of its 2030 emissions intensity reduction goal, acknowledging potential substantial impacts on fleet and operating costs from future environmental regulations.

Management Comments

• "Our vision is to be the leading airline in the communities we serve, offering reliable, nonstop travel at unbeatable value."
• "We believe the ability of our board of directors to issue one or more series of preferred stock will provide us with flexibility in structuring possible future financings and in meeting other corporate needs that might arise."
• "We believe this new aircraft purchase will be complementary with our low cost strategy."
• "Our intent to retain ownership of the aircraft, coupled with the longer useful life for depreciation purposes is resulting in similar ownership expense when compared with used aircraft in our fleet."
• "The expected fuel savings, improved operational reliability, and other savings expected from the use of these new aircraft should aid in improving our overall low cost structure, and the lower cost of operating this aircraft is expected to allow us to profitably add new service or routes."
• "We believe the proposed transaction aligns with our long-term strategic objectives and is expected to enhance our network breadth, operational flexibility, and ability to respond to demand shifts, while supporting scheduled service, charter and cargo operations of both airlines."
• "We believe the combination of our two financially strong leisure carriers in the U.S. will create benefits for customers, communities, employees, and partners by enhancing stability, expanding opportunities, and enabling continued investment and innovation."
• "We believe we have more than adequate liquidity resources through our cash, cash equivalents and short term investment balances, financing commitments, our undrawn capacity under existing credit facilities, operating cash flows and anticipated access to liquidity, to meet our current contractual obligations and remain in compliance with the debt covenants in our existing financing agreements for the next 12 months."
• "We continue to believe that the addition of the 737 MAX aircraft will be safe, reliable and accretive to our profitability."
• "We believe our under-served city strategy with less than daily service has reduced the intensity of competition we might otherwise face."
• "We believe our low cost structure is essential to competitive success in the airline industry, particularly as a solely leisure focused carrier."
• "We believe our co-brand credit card and non-card loyalty program may be particularly attractive to our customers in the small to mid-sized cities served by us as there are few other airlines that operate service from those cities and as a result, our loyalty programs offer rewards these customers may highly value."
• "We believe that solidifying our commitment to sustainability efforts is a natural integration into our long-term corporate strategy and will enable us to better serve our stakeholders."

Industry Context

StockSavvy.ai notes that Allegiant's focus on under-served cities and leisure travelers, coupled with its low-cost, high-ancillary revenue model, continues to differentiate it from legacy carriers and even other low-cost carriers that often target larger markets. The proposed acquisition of Sun Country Airlines, another leisure-focused carrier, suggests a strategic move to consolidate market share and achieve greater scale within this niche, potentially enhancing network breadth and operational flexibility in a highly competitive and volatile industry. The emphasis on direct distribution and data analytics aligns with broader industry trends towards personalized customer experiences and cost optimization. The ongoing pilot negotiations and expected wage increases reflect a significant industry-wide challenge in labor costs and talent retention, a common theme across the airline sector.

Comparison to Industry Standards

• The airline operating cost per available seat mile (CASM), excluding fuel, special charges, and Sunseeker Resort, was 8.04 cents in 2025, which is believed to be among the lowest in the industry and significantly lower than legacy carriers such as Delta Air Lines, American Airlines, and United Airlines.
• Operates to more cities than any non-legacy U.S. carrier, with 75% of its routes having no nonstop competition, indicating a unique market position compared to traditional hub-and-spoke models used by major airlines.
• The new Boeing 737 MAX aircraft are expected to burn up to 20% less fuel on a per-passenger basis compared to the existing used Airbus fleet, aligning with industry efforts for improved fuel efficiency and reduced emissions.
• Pilot pay scales have increased significantly across the industry, and the company expects its next contract to reflect these 'industry competitive rates,' indicating a response to broader labor market trends affecting airlines like Southwest Airlines, Spirit Airlines, and Frontier Airlines.
• The co-brand credit card has been voted the No. 1 Best Airline Credit Card for seven consecutive years, and the Allways Rewards program rated the No. 1 Best Frequent Flyer Program for two consecutive years by USA Today, suggesting superior performance in loyalty programs compared to competitors.

Management Changes

Corporate Governance

Legal Proceedings

• Subject to certain legal and administrative actions considered routine to business activities.
• Management believes the ultimate outcome of any pending legal or administrative matters will not have a material adverse effect on financial position, liquidity, or results of operations.
• Potential for litigation or arbitration by unions or individual employees related to the proposed Sun Country acquisition, which could delay or halt the merger or result in monetary damages.

Stakeholder Impact

• **Shareholders**: Potential for long-term value creation from the Sun Country acquisition and Allegiant ONE strategy, but also faces dilution from new share issuance, stock price volatility, and the indefinite suspension of dividends.
• **Employees**: Ongoing pilot negotiations are expected to result in significantly higher pay rates, and there is potential for labor disputes during the Sun Country integration. Corporate restructuring in April 2025 included voluntary separation packages for some personnel.
• **Customers**: Benefit from an expanded route network and improved operational reliability (99.9% controllable completion). Enhanced loyalty programs offer more value, but potential for higher fares exists due to increased operating costs (fuel, labor).
• **Suppliers**: Continued reliance on Boeing for aircraft deliveries, with potential for delays impacting fleet growth plans.
• **Creditors**: Increased indebtedness post-acquisition could limit financial flexibility, and covenants in debt agreements may restrict certain business activities.

Next Steps

• Closing of the proposed acquisition of Sun Country Airlines is expected in the second half of 2026, subject to shareholder and regulatory approvals.
• Integration of Sun Country's operations and employee groups, including negotiation of joint collective bargaining agreements where necessary, will commence post-acquisition.
• Completion of the replacement of flight and crew management systems with a next-generation platform powered by CAE is expected during 2026.
• Redevelopment of certain internal-use software is expected to be completed by the fourth quarter of 2026.
• Continued mediation with the International Brotherhood of Teamsters for a successor collective bargaining agreement for pilots is ongoing.
• Negotiations for a new collective bargaining agreement for dispatchers will commence as their current agreement becomes amendable in May 2026.
• Expected delivery of 11 Boeing 737 MAX aircraft in 2026, 15 in 2027, and the remainder in 2028.
• Continued focus on strategic utilization of the fleet, particularly during peak demand periods, with minimal scheduled service growth expected in 2026.
• Ongoing assessment of sustainable aviation fuels (SAF) as part of the sustainability strategy for reaching emissions intensity reduction goals by the end of 2030.
• The annual meeting of shareholders is scheduled for June 25, 2026.

Key Dates

Recommendation

Allegiant's 2025 performance shows strong operational improvements and strategic growth initiatives, particularly the Sun Country acquisition and network expansion. However, the reported net loss, significant special charges, and the substantial financial and integration risks associated with the merger, coupled with ongoing labor cost pressures and potential Boeing delivery delays, create considerable near-term uncertainty. A seasoned investor would likely maintain a "hold" position, awaiting clearer execution on the merger integration and resolution of labor negotiations before committing further capital, while acknowledging the long-term strategic potential.
