#### Merger Agreement Closing
On May 13, 2026 (the "<u>Closing Date</u>"), Allegiant Travel Company, a Nevada corporation ("<u>Allegiant</u>"), completed the previously announced acquisition of Sun Country Airlines Holdings, Inc., a Delaware corporation ("<u>Sun Country</u>"), pursuant to the Agreement and Plan of Merger (the "<u>Merger Agreement</u>"), dated January 11, 2026, by and among Allegiant, Sun Country, Mirage Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of Allegiant ("<u>Merger Sub 1</u>"), and Sawdust Merger Sub, LLC, a Nevada limited liability company and a direct wholly owned subsidiary of Allegiant ("<u>Merger Sub 2</u>"), providing for the merger of Merger Sub 1 with and into Sun Country (the "<u>First Merger</u>"), with Sun Country surviving the First Merger as a direct wholly owned subsidiary of Allegiant, and immediately following the effective time of the First Merger (the "<u>First Effective Time</u>"), the merger of Sun Country with and into Merger Sub 2 (the "<u>Second Merger</u>" and, together with the First Merger, the "<u>Mergers</u>"), with Merger Sub 2 surviving the Second Merger as a direct, wholly owned subsidiary of Allegiant. As a result of the Mergers, Sun Country became a wholly owned subsidiary of Allegiant on the Closing Date. Capitalized terms used herein but not otherwise defined have the meanings set forth in the Merger Agreement.

As previously disclosed, pursuant to the Merger Agreement and by virtue of the First Merger, at the First Effective Time, each issued and outstanding share ("<u>Share</u>") of common stock, par value $0.01 per share of Sun Country ("<u>Sun Country Common Stock</u>"), was converted into the right to receive (i) $4.10 in cash, without interest (the "<u>Per Share Cash Consideration</u>") and (ii) 0.1557 (the "<u>Merger Exchange Ratio</u>") shares of Allegiant common stock ("<u>Allegiant Common Stock</u>"), par value $0.001 per share (the "<u>Per Share Stock Consideration</u>" and, together with the Per Share Cash Consideration, the "<u>Merger Consideration</u>").

Pursuant to the Merger Agreement, effective as of immediately prior to the First Effective Time, by virtue of the Mergers:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• All outstanding stock options to purchase shares of Sun Country Common Stock granted pursuant to any Company Equity Award Plan, whether vested or unvested and regardless of
 exercise price, were automatically converted into stock options for Allegiant immediately before the First Effective Time, with no action required by the holder (the " Converted Options "
 and each a " Converted Option "). Each Converted Option covers a proportionately adjusted number of shares of Allegiant Common Stock and has a proportionately adjusted exercise
 price, in each case as determined in accordance with Section 2.5 of the Merger Agreement. The Converted Options continue to be governed by the same vesting schedules and terms, including any double-trigger vesting protections;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Each outstanding Company RSU Award was assumed by Allegiant and converted into a Parent RSU Award covering a number of shares of Allegiant Common Stock as determined in
 accordance with Section 2.5 of the Merger Agreement. The Parent RSU Awards continue to have the same terms and conditions as the Company RSU Awards, including any double-trigger vesting protections;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Each outstanding Company PRSU Award was assumed by Allegiant and converted into a Parent PRSU Award covering a number of shares of Allegiant Common Stock as determined in
 accordance with Section 2.5 of the Merger Agreement, with the underlying number of shares deemed to equal 125% of the target number of shares subject to the Company PRSU Award. The Parent PRSU Awards continue to have the same terms and
 conditions as the Company PRSU Awards, including any double-trigger vesting protections, provided that there will no longer be any performance-based vesting conditions, and the Parent PRSU Award is a time-vesting award eligible to vest on
 the last day of the performance period applicable to the Company PRSU Award; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• With respect to non-employee Sun Country board members and former employees/service providers to Sun Country, each Company Equity Award held by such individuals became fully vested (to the extent
 not yet vested), cancelled and converted into the right to receive the Merger Consideration.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

---

On the Closing Date, effective as of the effective time of the Second Merger, as approved by resolutions of Allegiant's board of directors (the "Allegiant Board") and pursuant to the terms of the Merger Agreement, the Allegiant Board approved and adopted an amendment to Allegiant's bylaws (the "Bylaws Amendment") to change the number of directors on the Board from eight to eleven, and three directors designated by Sun Country joined the Allegiant Board: (i) Jude Bricker, the President and CEO of Sun Country, and current member of the Sun Country board of directors (the "<u>Sun Country Board</u>"), (ii) Jennifer Vogel, a current member of the Sun Country Board, and (iii) Thomas Kennedy, a current member of the Sun Country Board. As approved by resolutions of Allegiant's Board, Ms. Vogel was placed on the Compensation Committee of the Board, and Mr. Kennedy was placed on the Audit Committee of the Board. Other than with respect to Mr. Bricker's fee arrangement pursuant to the Advisory Services Agreement (as defined below), Mr. Bricker, Ms. Vogel and Mr. Kennedy will receive compensation for service as a non-employee director consistent with the compensation arrangements applicable to Allegiant's other non-employee directors.

Mr. Bricker, age 52, has served as President and CEO of Sun Country 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.

Ms. Vogel, age 64, has served as Chair of the Sun Country 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.

Mr. Kennedy, age 60, has served on the Sun Country Board since 2021. He is President and CEO, North America at SIXT Rental Car since January 2025 and previously served as its President and CFO from 2020. 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.

As previously disclosed, on April 8, 2026, Allegiant entered into an Advisory Services Agreement with Jude Bricker (the "Advisory Services Agreement"), which will become effective the day after the consummation of the Mergers. Under the Advisory Services Agreement, Mr. Bricker will serve as an independent contractor and provide advisory services relating to the integration of Sun Country into Allegiant, obtaining a single operating certificate for Allegiant Air, LLC and Sun Country, retention of charter and cargo customers and Sun Country business, continuity of Sun Country business relationships and consultation regarding the airline industry and the businesses of Allegiant and Sun Country. Mr. Bricker will be paid $26,250 per month during the term of the Advisory Services Agreement and will also be reimbursed for reasonable out-of-pocket expenses in accordance with Allegiant's expense reimbursement procedures. This fee is separate from any compensation payable to him for service on the Allegiant Board. The Advisory Services Agreement continues until the earliest of Allegiant obtaining a single operating certificate for Sun Country, Mr. Bricker no longer serving on the Allegiant Board, or 15 days after Allegiant gives notice of termination, except that if any of those events occurs within the first 12 months after the effective date, the Advisory Services Agreement will remain in place until the first anniversary unless the parties agree otherwise. Mr. Bricker will not be eligible for employee benefits under the arrangement.

**WHEREAS**, the Company has entered into an Agreement and Plan of Merger, dated as of January 11, 2026, by and among the Company, Mirage Merger Sub, Inc., a Delaware corporation and a direct wholly owned Subsidiary of the Company ("<u>Merger Sub 1</u>"), Sawdust Merger Sub, LLC, a Nevada limited liability company and a direct wholly owned Subsidiary of the Company ("<u>Merger Sub 2</u>" and, together with Merger Sub 1, "<u>Merger Subs</u>") and Sun Country Airlines Holdings, Inc., a Delaware corporation (the "<u>Sun Country</u>" and, such agreement, the "<u>Merger Agreement</u>"), pursuant to which Merger Sub 1 will merge with and into Sun Country, with Sun Country surviving as a direct, wholly owned subsidiary of the Company and, immediately thereafter, Sun Country will merge with and into Merger Sub 2, with Merger Sub 2 surviving as a direct, wholly owned subsidiary of Allegiant (the "<u>Closing</u>") on the terms and subject to the conditions set forth therein;

**WHEREAS**, Advisor currently serves as the President and Chief Executive Officer of Sun Country pursuant to the Employment Agreement, dated as of April 11, 2023, by and between Sun Country and Advisor (the "<u>Employment Agreement</u>");

**WHEREAS**, effective as of, and contingent upon, the Closing, Advisor shall terminate employment from all employee, officer, manager, director and/or other similar positions held by Advisor at Sun Country and any of its subsidiaries in accordance with Section 4(a)(v) of the Employment Agreement; and

**WHEREAS**, the Company and Advisor (the "<u>Parties</u>") desire that Advisor provide advisory services to the Company commencing on the day immediately following the Closing (the "<u>Effective Date</u>") in accordance with the terms and conditions set forth in this Agreement.

**NOW**, **THEREFORE**, in consideration of the foregoing and the mutual promises and covenants herein contained, the Parties agree as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.&nbsp;&nbsp;&nbsp;&nbsp; <u>Services to be Rendered</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp; The Company hereby retains Advisor commencing on the Effective Date as an independent contractor to provide the advisory services to the Company set forth on <u>Exhibit A</u> attached hereto and such other services as reasonably requested by the Chief Executive Officer of the Company from time to time (collectively, the "<u>Services</u>").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp; Advisor shall provide the Services as reasonably requested in writing by the Chief Executive Officer of the Company, subject to reasonable limitations concerning time and place, and shall report to the Chief Executive Officer of the Company, for project work as clarified in the scope of the written request.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Advisor represents and warrants that Advisor shall act honestly and in good faith and in the best interests of the Company and its affiliates at all times while providing the Services, and that Advisor shall use all of Advisor's professional care, diligence and skill to ensure that the Services are provided and completed to the reasonable satisfaction of the Company. Advisor represents and warrants that Advisor shall comply with all applicable laws, regulations, rules, codes, orders and standards imposed by applicable federal, state, provincial, or local government authorities with respect to the provision of any Services, and Advisor shall not subcontract the provision of any Services to any third party without receiving prior written consent from the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.<u>Advisory Fees</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp; As compensation for the Services performed by Advisor, the Company shall pay Advisor $26,650 per month (the "<u>Monthly Payment</u>") over the duration of the Term (as defined below) of this Agreement. The Monthly Payment shall be made as soon as reasonably practicable following the final business day of the month for which the Services were performed and shall be prorated based on the number of full days during which Advisor was engaged by the Company for any partial months, as applicable. Such Monthly Payments shall be the only compensation due to Advisor for the performance of the Services hereunder and shall be separate from, and in addition to, any compensation or other amounts payable to Advisor in his capacity as a member of the Board of Directors of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp; In addition to the Monthly Payment set forth in Section 2(a), the Company shall reimburse Advisor for Advisor's reasonable out-of-pocket expenses incurred in connection with the Services in accordance with the Company's existing expense reimbursement procedures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The Company shall not withhold from compensation payable under this Agreement any income, social security, or other taxes. Advisor acknowledges that Advisor is solely responsible for the payment of all taxes that may result from performance of the Services and with respect to the payment of the advisory fees and the Company shall not be in any way liable for any such taxes or penalties. Advisor understands and agrees that the Company shall have no responsibility whatsoever regarding any tax consequences arising from any payments made under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.<u> </u><u>Term of Agreement; Termination</u>. The term of this Agreement (the "<u>Term</u>") shall begin on the Effective Date and shall continue in full force and effect until the earliest to occur of (x) the date that the Company receives a single operating certificate in respect of Sun Country, (y) the date that Advisor ceases to serve on the Board of Directors of the Company, or (z) fifteen (15) days after the Company provides Advisor with written notice (email is sufficient) that the Company wishes to terminate this Agreement; <u>provided</u>, that if (x), (y) or (z) occur within twelve (12) months following the Effective Date, the Term shall expire on the twelve (12) month anniversary of the Effective Date. The parties may mutually agree to extend this Agreement.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.&nbsp;&nbsp;&nbsp;&nbsp; <u>Status as Independent Contractor</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp; Advisor and the Company understand and acknowledge that, as of the Effective Date, Advisor's relationship with the Company shall be that of an independent contractor and nothing in this Agreement creates a partnership, joint venture or any employer-employee relationship between Advisor on the one hand and the Company on the other hand. The Company shall not have the authority to, nor shall it, supervise, direct or control the manner, means, details or methods utilized by Advisor to perform the Services under this Agreement. Nothing contained in this Agreement is intended to nor shall it prevent Advisor from simultaneously becoming engaged by any other person or entity during the Term; <u>provided</u>, however, Advisor shall remain bound by, and shall not violate the covenants set forth in the Employment Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp; Advisor acknowledges and agrees that (i) Advisor is not eligible to participate in and waives any claims he may have to any type of benefits offered to employees of the Company (other than those to which he might be entitled as a former employee of Sun Country) and (ii) neither Advisor nor any individual employed by Advisor or acting on Advisor's behalf shall be treated or regarded as a Company employee under the laws or regulations of any government or governmental agency.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp; It is further agreed that the Company (i) shall have no obligation to provide Advisor with any business registrations or licenses required to perform the Services; (ii) does not pay Advisor a salary; and (iii) shall not combine business operations with Advisor, but instead shall keep the operations of Advisor and the Company separate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp; Advisor is not an agent of the Company or its affiliates and shall have no authority to make any statement, representation, or commitment of any kind or to take any action binding upon the Company without the Company's prior written authorization and shall have no management authority with respect to the Company. Since Advisor is an independent contractor under this Agreement, any personal injury or property damage suffered by Advisor in the course of performing Services under this Agreement shall be Advisor's sole responsibility.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)The Company and Advisor acknowledge and agree that on the Closing Advisor had a "separation from service," within the meaning of section 409A of the Internal Revenue Code of 1986, as amended. The Parties reasonably expect that the performance of the Services will not require Advisor to provide more than twenty percent (20%) of the average level of services rendered by Advisor to the Company and its affiliates during the thirty-six (36) months immediately preceding the Effective Date; <u>provided</u>, <u>that</u>, the Parties understand and agree that, generally, the Services shall not require Advisor to work more than an average of fifteen (15) hours per month.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.&nbsp;&nbsp;&nbsp;&nbsp;<u> </u><u>Assignment</u>. Advisor shall not assign any of Advisor's rights under this Agreement, or delegate the performance of any of Advisor's duties hereunder, without the prior written consent of the Company, which it may withhold for any or no reason.

#### Allegiant Completes Acquisition of Sun Country Airlines, Creating the Leading Leisure-Focused U.S. Airline

*Combination expands network, enhances scale, and strengthens diversified operations*

**LAS VEGAS. May 13, 2026** – Allegiant Travel Company (<u>NASDAQ: ALGT</u>) today announced it has successfully completed its acquisition of Sun Country Airlines Holdings, Inc. (NASDAQ: SNCY), bringing together two complementary carriers focused on affordable leisure travel. The transaction closed following satisfaction of customary closing conditions, including receipt of required regulatory approvals and approval by the shareholders of each of Allegiant and Sun Country.

The combination strengthens Allegiant's position as a leading U.S. leisure airline by expanding its network, increasing scale, and enhancing its diversified operating model.

"Today marks a defining moment in Allegiant's history as we officially join forces with Sun Country to create the leading leisure-focused airline in the United States," said Allegiant CEO Gregory C. Anderson. "With a combined fleet of 195 aircraft serving nearly 175 cities, we are expanding access to affordable, reliable, and convenient travel for the communities that have long been the foundation of our business, while offering customers broader reach and more destinations. By bringing together two strong airlines with similar business models, we are creating a more differentiated and durable airline – one well positioned to deliver lasting value for our customers, team members, and shareholders. I want to recognize Team Allegiant and Team Sun Country, whose dedication and hard work made this day possible."

Customers can continue to book travel through existing channels, and there are no changes to current reservations, flight schedules, or travel plans. Both airlines will continue to operate as separate carriers in the near term, maintaining their respective brands. Allegiant Allways Rewards and Sun Country Rewards will remain separate in the near term, and members' points, benefits, and account status will retain their current value. Customers should continue to manage reservations, check in, and access customer service through the airline with which they booked travel. Over time, Allegiant expects to introduce additional benefits that make it easier for customers to access the combined network.

The combined company is committed to a thoughtful and disciplined integration process focused on maintaining safe, reliable operations and delivering a consistent customer experience. There are no immediate changes to frontline roles, and operational employees will continue in their current positions. The company will work closely with labor representatives throughout the integration process, and all existing collective bargaining agreements will remain in place. At the corporate level, some roles may overlap as functions are integrated. Any potential changes will be evaluated carefully, with a focus on fairness, respect, and clear communication.

Allegiant values Sun Country's deep roots in Minnesota and expects Minneapolis-St. Paul to remain an important operating center for the combined company. The combined company is committed to maintaining strong relationships with the communities, airports, customers, and partners served by both airlines, while continuing to support the leisure-focused markets that have been central to each company's success.

Together, Allegiant and Sun Country will serve approximately 22 million annual customers across nearly 175 cities, with more than 650 routes and a combined fleet of 195 aircraft.

The combination brings together complementary strengths, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Expanded access to leisure destinations across the U.S. and select international markets

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A diversified model supported by scheduled service, charter, and cargo operations

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increased scale to support long-term growth and operational resilience

Financially, the combination of Allegiant and Sun Country brings together two profitable airlines with complementary networks, diversified revenue streams and strong balance sheets, creating a platform with meaningful long-term value creation potential. Allegiant expects to realize approximately $140 million in annual synergies within three years following closing and integration, driven by expanded customer choice across the combined network, scale efficiencies, fleet optimization, and procurement benefits. The transaction is expected to be accretive to earnings per share in the first full year post-closing, while maintaining balance sheet flexibility.

Sun Country's cargo operations for Amazon Prime Air and charter contracts with casinos, Major League Soccer, collegiate sports teams, and the Department of Defense, complement Allegiant's existing charter business and further diversify the combined company's revenue base. With 195 aircraft at closing, 30 aircraft on order and an additional 80 options, the combined company will have greater flexibility to optimize aircraft deployment, improve utilization, and support long-term growth through economic cycles.

Greg Anderson will serve as Chief Executive Officer of the combined company, and Robert Neal will serve as President and Chief Financial Officer. Jude Bricker, Jennifer Vogel and Thomas C. Kennedy were appointed as members of Allegiant's Board of Directors.

In connection with the closing, Sun Country common stock has ceased trading on the NASDAQ, and Allegiant Travel Company will continue to trade on the NASDAQ under the ticker symbol "ALGT."
