Management Comments

• "We believe there are many benefits to this combination. We are creating a leading, more competitive leisure-focused U.S. airline."
• "Together, we will be more competitive and deliver meaningful value for our team, customers and the communities we serve."
• "Our networks are highly complementary, which means expanded choices for our customers, particularly in and out of Minneapolis-St. Paul (MSP)."
• "Since the merger is designed to increase the size of the airline, we do not expect any reductions to front-line positions."
• "MSP will remain a key anchor city for the combined airline and we will maintain a significant presence in Minneapolis-St. Paul."
• "Allegiant recognizes how important MSP is to Sun Country, as well as our operations in the region. As a combined company with more scale and resources, we will plan on growing our presence in MSP."
• "Our charter business is a core differentiator that Allegiant fully intends to grow alongside its own charter business with the expanded resources that will come from the combined company."
• "There is no impact on our partnership with Amazon. Supporting Amazon remains an important part of our operations, and we remain focused on delivering safe, reliable freight service."

Industry Context

This merger represents a significant consolidation within the U.S. leisure airline sector, aiming to create a larger, more resilient player. By leveraging complementary networks, the combined entity seeks to expand its reach and service offerings, potentially intensifying competition for other low-cost carriers and traditional airlines in leisure markets. The emphasis on unique business models, including charter and cargo operations, suggests a strategic move to diversify revenue streams beyond traditional passenger services, a trend observed in parts of the aviation industry to mitigate market volatility and enhance adaptability.

Comparison to Industry Standards

• The combined entity's scale, with nearly 175 cities, over 650 routes, and a fleet of 195 aircraft, positions it as a substantial player in the U.S. leisure market, comparable to other mid-tier U.S. airlines focusing on specific market segments.
• The strategy of combining complementary networks and unique business models (charter, cargo) aims to differentiate the new entity from larger legacy carriers (e.g., Delta, American, United) and even other low-cost carriers (e.g., Southwest, Spirit, Frontier) by offering a broader range of services and market reach in leisure destinations.
• With 22 million annual passengers, the combined airline would be a top-tier specialized leisure airline, potentially challenging the market presence of companies like Frontier or Spirit in certain leisure-focused routes, though still smaller than the largest U.S. carriers.

• **Suppliers/Business Partners**: Potential for adverse reactions or changes in business relationships due to the merger, as noted in the risk factors.

Next Steps

• Sun Country and Allegiant will continue to operate separately until the transaction closes.
• A joint cross-functional integration planning team will be formed to determine how to most effectively bring the businesses together.
• Required shareholder and regulatory approvals must be obtained for the transaction to close.
• Allegiant intends to file a registration statement on Form S-4 (including a prospectus and joint proxy statement/prospectus) with the SEC.
• The definitive joint proxy statement will be mailed to stockholders of Allegiant and Sun Country.
• Following close, the corporate entity will be named Allegiant.
• Each airline will operate separately until a single operating certificate is obtained from the FAA, consolidating operations, procedures, and safety protocols.

Key Dates

Recommendation

The proposed merger between Sun Country and Allegiant presents strategic benefits, including enhanced market position, expanded networks, and diversified business models, which could unlock significant synergies. However, the transaction is subject to substantial regulatory and shareholder approvals, with an expected closing in the second half of 2026, introducing a prolonged period of uncertainty. The filing also highlights numerous integration risks, potential management transitions, and dilution for Allegiant shareholders. While the long-term outlook appears positive, the immediate future involves considerable execution risk and a lengthy timeline. Therefore, a 'hold' recommendation is appropriate for seasoned investors to monitor the progress of approvals, integration planning, and the realization of anticipated benefits before making further investment decisions.
