CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING AND OTHER STATEMENTS

This Proxy Statement contains forward-looking statements within the meaning of the federal securities laws. Forward-looking statements are those that predict or describe future events or trends and that do not relate solely to historical matters. Forward-looking statements may be identified by words like “anticipate,” “expect,” “believe,” “plan,” “may,” “estimate,” “intend” and other similar words. These forward-looking statements are based on our beliefs, assumptions and estimates using information available to us at the time and are not intended to be guarantees of future events or performance. Forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from historical experience or the Company’s present expectations. Factors that may cause actual results to differ materially from those contemplated by the statements in this Proxy Statement can be found in our most recent Annual Report on Form 10-K filed with the SEC and in the Quarterly Reports on Form 10-Q that we have filed or will file hereafter under the heading “Risk Factors” and “Safe Harbor for Forward-Looking Statements.” Some of these risks include competition; labor costs, relations, and availability; general economic conditions; increases in operating costs, including fuel; geopolitical developments, including military operations, sanctions and related impacts on fuel cost and airspace availability; uncertainties regarding the ability to successfully integrate the operations of the acquisition of Hawaiian Holdings, Inc. and the ability to realize anticipated benefits from such acquisition; inability to meet cost reduction and other strategic goals; seasonal fluctuations in demand and financial results; supply chain risks; events that negatively impact aviation safety and security; the ability to use net operating loss carryforwards; and changes in laws and regulations that impact our business.

The forward-looking statements speak only as of the date of this Proxy Statement and undue reliance should not be placed on these statements. We disclaim any intention or obligation to publicly update or revise any forward-looking statements. This cautionary statement is applicable to all forward-looking statements contained in this document.

This Proxy Statement contains statements regarding individual and Company performance objectives and targets. These objectives and targets are disclosed in the limited context of our compensation plans and programs and should not be understood to be statements of management’s future expectations or estimates of future results or other guidance. We specifically caution investors not to apply these statements to other contexts.

Furthermore, certain statements in this Proxy Statement, particularly pertaining to our sustainability performance, goals and initiatives, are subject to additional risks and uncertainties, including regarding: gathering and verification of information and related methodological considerations; our ability to implement various initiatives under expected timeframes, cost, and complexity; our dependency on third-parties to provide certain information and to comply with applicable laws and policies; our reference to various sustainability reporting standards and frameworks (including standards for the measurement of underlying data), which continue to evolve; and other unforeseen events or conditions. These factors, as well as others, may cause results to differ materially and adversely from those expressed in any of our forward-looking statements. Additionally, we may provide information herein that is not necessarily “material” under the federal securities laws for SEC reporting purposes but that is informed by various sustainability standards and frameworks (including standards for the measurement of underlying data) and the interest of various stakeholders. However, we cannot guarantee strict adherence to framework recommendations and much of this information is subject to assumptions, estimates or third-party information that is still evolving and subject to change, and our disclosures based on these frameworks may change due to revisions in framework requirements, availability of information, changes in our business or applicable governmental policy, or other factors, some of which may be beyond our control.
