Industry Context

This merger signifies a strategic move within the U.S. airline industry towards consolidation and specialization, particularly in the leisure travel segment. By combining two financially strong, leisure-focused carriers, Allegiant and Sun Country aim to create a more adaptable and resilient airline model. This aligns with broader industry trends seeking to optimize capacity, diversify revenue streams (e.g., through charter and cargo operations), and enhance customer offerings to navigate competitive pressures and economic fluctuations. The expansion into international leisure destinations also reflects a growing market opportunity for U.S. carriers.

Comparison to Industry Standards

• The combined entity aims to create "one of the most adaptable and resilient airline models in the industry," suggesting a benchmark against other airlines' operational flexibility and market responsiveness.
• The target Net Adjusted Debt to EBITDAR of less than 3.0x post-closing is a common leverage metric, indicating a commitment to maintaining a strong financial position relative to industry peers.
• The combined fleet of approximately 195 aircraft (with 30 on order and 80 options) positions the company as a significant player in the U.S. market, comparable in scale to other major carriers.
• The ability to own and operate both Airbus and Boeing aircraft provides a strategic advantage in fleet flexibility and sourcing, differentiating it from many airlines that typically operate a single manufacturer's fleet.
• Sun Country's diversified revenue streams, including a multi-year agreement with Amazon Prime Air for freighter operations and charter contracts with casinos, Major League Soccer, collegiate sports teams, and the Department of Defense, offer a more robust and resilient business model compared to purely passenger-focused airlines, which is a key industry differentiator.
