Key Financial Metrics
This filing is a current report regarding a corporate event and does not contain financial statements, revenue, profit, cash flow, margin, debt, or liquidity metrics for Allegiant Travel Co. or Sun Country Airlines.
Material Changes
The primary material change reported is the early termination of the statutory waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (HSR Act) for the proposed merger.
