Allegiant Travel Company and Sun Country Airlines have received early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act for Allegiant’s proposed acquisition of Sun Country, marking a key regulatory milestone for the transaction.
Early termination indicates that the US Department of Justice has completed its initial antitrust review without requiring a more extensive investigation, effectively clearing the deal from a US competition standpoint.
The companies said the transaction remains subject to additional closing conditions, including approval from the US Department of Transportation for an interim exemption application as well as shareholder approval from both airlines.
Allegiant CEO Greg Anderson said the companies were “pleased to receive US antitrust clearance” and remained confident the combination would create a stronger leisure-focused airline with a broader network and more travel options.
The companies now expect the transaction to close in the second or third quarter of 2026.
