for Allegiant’s Proposed Acquisition of Sun Country
LAS VEGAS and MINNEAPOLIS, March 16, 2026 – (PRNewswire) – Allegiant Travel Company (NASDAQ: ALGT) (“Allegiant”) and Sun Country
Airlines (NASDAQ: SNCY) (“Sun Country”) today announced the early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 in connection with Allegiant’s previously announced proposed
acquisition of Sun Country. Receiving U.S. antitrust clearance is an important step toward completing the combination of the two airlines.
The proposed
transaction remains subject to other customary closing conditions, including approval from the U.S. Department of Transportation (DOT) of an interim exemption application and the approval of the shareholders of each of Allegiant and Sun Country. The
transaction is now expected to close in the second or third quarter of 2026.
“We are pleased to receive U.S. antitrust clearance from the
Department of Justice,” said Allegiant CEO Greg Anderson. “We remain confident that this combination will deliver meaningful benefits for our customers, team members and the communities we serve. Together, Allegiant and Sun Country will
create a stronger leisure-focused airline, offering a broader network, more travel options and increase long-term value creation for our shareholders.”
