Management Comments

• Gregory C. Anderson (Allegiant CEO): "This combination is an exciting next chapter in Allegiant and Sun Countrys shared mission in providing affordable, reliable, and convenient service from underserved communities to premier leisure destinations. We have long admired Sun Country for their well-run, flexible, and diversified business model that optimizes for year-round utilization and strong margins. Together, our complementary networks will expand our reach to more vacation destinations including international locations. With our combined strengths including operational excellence, consistent profitability, strong balance sheets, and fleet ownership, we will create an even more resilient and agile airline that delivers greater value to travelers, partners, Team Members, shareholders, and the communities we serve."
• Jude Bricker (Sun Country President & CEO): "Over Sun Countrys 43-year history, we have grown to become one of the nations most respected low-cost, leisure airlines with a unique business model for serving scheduled service and charter passengers as well as delivering cargo, with a strong brand and deep roots in Minnesota.

Importantly, we believe this transaction delivers significant value to Sun Country shareholders and an opportunity to continue to benefit from our growth plans as a combined company."
• Gregory C. Anderson (Allegiant CEO): "In our industry, size, scale, and relevancy have their advantages. Currently, five airlines control approximately 85 percent of the domestic market.

Since the onset of the pandemic, most of these carriers have faced significant financial difficulties and losses – except for Sun Country and our company, both of which have consistently reported positive earnings."
• Gregory C. Anderson (Allegiant CEO): "Another positive feature, there is no overlap between our bases. This independence will minimize the traditional friction that has occurred in past other airline combinations."
• Gregory C. Anderson (Allegiant CEO): "As the acquiring airline, its important we handle this process with professionalism, humility, and respect toward our future colleagues. Sun Country runs a solid operation with talented people. In many ways, we are cut from the same cloth. Given the close connections between our two companies, I am confident that together, we will build an even stronger airline."
• Jude Bricker (Sun Country President & CEO): "I’ve had the privilege of working with both airlines and I can say with confidence that this combination is an exceptional fit in every way – for our customers, our employees, and our communities. In fact, Sun Country’s first ever flight landed in Las Vegas, Allegiant’s headquarters."

Industry Context

The merger creates a larger, more competitive leisure-focused U.S. airline in an industry where five major carriers control approximately 85% of the domestic market. Both Allegiant and Sun Country have demonstrated consistent profitability since the pandemic, unlike many other smaller leisure carriers that faced significant financial difficulties. This combination leverages their similar flexible capacity models and diversified revenue streams (scheduled service, charter, cargo) to enhance resilience and market position, particularly in underserved leisure markets and international destinations. The move reflects a trend towards consolidation and strategic partnerships to achieve scale, optimize operations, and improve financial stability in a volatile industry.

Comparison to Industry Standards

• Both Allegiant and Sun Country are highlighted as having 'industry leading margins' and 'successful, flexible capacity, operating models' compared to 'Big Four Carriers' (American, Delta, Southwest, United) and 'Other U.S. Carriers' (Alaska, Frontier, JetBlue, Spirit, Breeze, Avelo).
• The combined company is positioned as 'highly profitable while other leisure carriers lose money,' based on cumulative adjusted net income since 2021, contrasting with other leisure carriers like Frontier, Spirit, JetBlue, Breeze, and Avelo which show cumulative losses.
• The combined entity's flexible capacity model, which allows for concentrating flying during peak leisure demand, is presented as superior to 'less capacity optimization' and 'more diffuse flying' of other leisure carriers.
• The combined fleet's embedded equity value of $2.2 billion and the ability to operate both Airbus and Boeing aircraft provide 'significant future fleet optionality' and 'enhanced fleet optimization' compared to potentially less flexible or more leveraged fleets of competitors.
• The combined company's diversified revenue streams, including cargo and charter contracts, are noted to provide 'unique stability among airlines' and 'greater resilience through economic cycles' compared to solely passenger-focused models.

Key Dates

Recommendation

The merger presents a compelling strategic rationale, combining two profitable leisure-focused airlines with complementary networks and diversified business models. The significant expected synergies ($140 million annually), projected EPS accretion within the first year, and a strong combined balance sheet (Net Adjusted Debt to EBITDAR < 3.0x) indicate substantial value creation for shareholders. The premium offered to Sun Country shareholders is attractive, and Allegiant shareholders retain a majority stake in a more resilient and agile airline. The lack of significant route overlap and the diversified revenue streams (passenger, charter, cargo) mitigate industry volatility risks, positioning the combined entity for sustained long-term growth and profitability.
