Allegiant Travel Company (ALGT) announced Sunday that it's buying Sun Country Airlines Holdings Inc. (SNCY) in a move that creates a larger leisure-focused airline with broader reach and a more diversified earnings profile. The deal values Sun Country at about $1.5 billion and offers shareholders a mix of 0.1557 Allegiant shares plus $4.10 in cash per share, implying a total value of $18.89 per share. That's roughly a 20% premium to where Sun Country closed on January 9.

Building a Bigger Leisure Network

Once combined, the airline would handle about 22 million passengers annually across nearly 175 cities, operating more than 650 routes with a fleet of approximately 195 aircraft. The strategic logic here is fairly straightforward: Allegiant's strength in smaller markets pairs nicely with Sun Country's presence in larger cities and international leisure destinations. Together, they'll offer more nonstop options to popular vacation spots, which is exactly where both carriers make their money.

More Than Just Passenger Seats

What makes Sun Country particularly attractive isn't just its scheduled flights. The airline has locked in long-term cargo and charter contracts that provide steadier cash flow through the inevitable ups and downs of leisure travel demand. That includes a multi-year agreement with Amazon.com, Inc. (AMZN) for Amazon Prime Air, plus charters for sports teams, casinos, and government clients. Allegiant already runs its own charter business, so combining these operations should smooth out revenue volatility.

The Financial Math

Allegiant's management is projecting $140 million in annual synergies by the third year after closing. They also expect the deal to boost earnings per share in the first full year of combined operations. On the balance sheet side, management forecasts net leverage below 3.0x at closing, which preserves some financial flexibility. For context, Allegiant reported total available liquidity of $1.2 billion as of September 30, 2025, including $991.2 million in cash and investments plus $175 million of undrawn revolving credit facilities.

Both boards have approved the transaction, which is expected to close in the second half of 2026, subject to regulatory and shareholder approvals. Allegiant will stay headquartered in Las Vegas and maintain a significant presence in Minneapolis–St. Paul, where Sun Country is based.

Price Action: Allegiant Travel shares were down 2.10% at $92.98 during premarket trading on Monday, while Sun Country Airlines shares jumped 12.87%.
