In January, Allegiant announced it was acquiring Sun Country in a transaction expected to close as early as May 13, 2026. The combination will form the leading, leisure-focused U.S. airline that is expected to expand affordable, convenient service to more vacation destinations domestically and internationally. After closing, the combined company will operate under the Allegiant name. The airlines will continue operating separately until receiving a single operating certificate from the FAA. There is expected to be no immediate change to ticketing or schedules, and customers can continue to book their flights through allegiant.com and suncountry.com."This combination marks a major achievement for both Allegiant and Sun Country, and we look forward to the Allegiant leadership team guiding the company forward," said Maurice J. Gallagher, Allegiant's founder and Board Chairman. He added, "The addition of Jude Bricker, Jennifer Vogel, and Thomas Kennedy to our Board reflects the governance structure established for the combined company in the Merger Agreement, and brings to the Allegiant Board even greater expertise in airlines, finance and corporate leadership that will benefit the shareholders, employees and customers of the combined companies."Joining the Board upon closing will be:Jude Bricker has served as President and CEO of Sun Country Airlines since 2017 and has been a Sun Country director since 2018. A seasoned aviation executive with two decades of industry experience, he previously served as Allegiant's Chief Operating Officer and held multiple leadership roles at Allegiant from 2006–2017, overseeing key commercial, operational, and financial functions. Earlier, he was a finance manager at American Airlines. He also served as an infantry officer in the United States Marine Corps from 1996 to 2002. Mr. Bricker holds a B.S. in Civil Engineering from Texas A&M University and an MBA from the University of Texas, and he is an independent director of SAS Airlines.Jennifer Vogel has served as Chair of the Sun Country Airlines Board since March 2023 and has been a director since 2022. She is a former senior airline legal and compliance executive, having served as Senior Vice President, General Counsel, Secretary, and Chief Compliance Officer of Continental Airlines (retired 2010). Ms. Vogel currently serves on the boards of AAR Corp. and the Telluride Regional Airport Authority and previously served on the board of Virgin America. She holds a BBA from the University of Iowa and a JD from the University of Texas.Thomas C. Kennedy has served on the Sun Country Airlines Board since 2021.

Mr. Kennedy is a former public-company CFO, including as CFO of Hertz Global Holdings, with earlier senior finance leadership roles at Hilton Worldwide and Northwest Airlines. He holds a BA in Economics from Tulane University and an MBA from Harvard University."We are excited to welcome these accomplished leaders to Allegiant's Board upon closing," said Gregory C. Anderson, CEO of Allegiant. "Their experience and perspective will be valuable as we continue building a stronger, differentiated airline that better serves the communities and customers across our combined network."The current Allegiant Board, led by Chairman Maurice J. Gallagher, will continue its oversight responsibilities, with the new members joining effective upon the completion of the Sun Country acquisition.Strategically, the combination brings together complementary route networks – Allegiant's focus on small and mid-sized markets and Sun Country's presence in larger cities – creating more than 650 routes (551 Allegiant routes and 105 Sun Country routes) and connecting Minneapolis–St. Paul to additional mid-sized markets while expanding nonstop access to popular leisure destinations.

Allegiant and Sun Country Achieve Key Regulatory Milestone with DOT ApprovalApril 15, 2026 5:00 PM
PR Newswire (US)

U.S. Department of Transportation Exemption Allows Both Airlines to Continue Operating Under Common Ownership Following Closing LAS VEGAS and MINNEAPOLIS, April 15, 2026 /PRNewswire/ -- Allegiant Travel Company (NASDAQ: ALGT) and Sun Country Airlines Holdings, Inc. (NASDAQ: SNCY) today announced that the U.S. Department of Transportation (DOT) has approved the joint interim exemption application of their respective airline subsidiaries that will allow both airlines to continue operating as separate carriers under common ownership after closing, pending further action by the DOT.

This milestone marks a significant step toward completing Allegiant's previously announced proposed acquisition of Sun Country.Under the terms of the approval, following the closing of the proposed transaction, Allegiant and Sun Country will continue to operate independently, preserving their unique business models, route networks, and customer experiences while advancing toward a single operating certificate. The companies believe this structure will enable both airlines to continue delivering value to customers, employees, and stakeholders while ensuring operational continuity."This approval underscores the strength of our shared vision and the thoughtful approach both teams have taken throughout this process," said Gregory C. Anderson, CEO of Allegiant. "We remain focused on bringing these organizations together in a way that builds on their strengths, while positioning the combined company for long-term growth and resilience."Jude Bricker, President and CEO of Sun Country, added: "We appreciate the DOT's review and approval of our joint request. This milestone allows us to move forward with confidence while continuing to serve our customers and communities without disruption."The grant of an exemption by the DOT satisfies the last remaining regulatory approval-related condition to the closing of the proposed transaction. The closing remains subject to the satisfaction or waiver of the remaining customary closing conditions, including the approval of the shareholders of each of Allegiant and Sun Country. Allegiant and Sun Country have scheduled their respective special meetings of shareholders for May 8, 2026. Subject to the satisfaction or waiver of the remaining conditions to closing, Allegiant and Sun Country now expect the closing to occur as early as May 13, 2026 following shareholder approval at the special meetings.The companies will continue to work collaboratively to prepare for closing and ensure a seamless transition that prioritizes safety, service, and operational excellence.About Allegiant – Together We Fly™
