Allegiant Travel Company has agreed to acquire Sun Country Airlines in a transaction valued at approximately $1.5 billion, representing a nearly 20% premium to Sun Country’s recent trading levels. Under the terms, Sun Country shareholders will receive $4.10 in cash plus 0.1557 shares of Allegiant common stock for each share held. The combined airline is projected to generate up to $140 million in annual cost synergies by the end of the third year post‐closing, driven by fleet optimization, shared maintenance facilities and consolidated administrative functions. The deal, which aims to create a more diversified leisure carrier with expanded route networks and improved unit economics, is expected to close in the second half of 2026 subject to regulatory and shareholder approvals.
