Cancellation of Prior Equity Securities

In accordance with the 2024 Bankruptcy's Plan of Reorganization, all equity securities in Spirit Airlines outstanding prior to the Effective Date, including Spirit Airlines' common stock, par value $0.0001 per share (the “Old Common Stock”), were canceled, released, and extinguished, and of no further force or effect and without any need for a holder of Old Common Stock to take further action with respect thereto. Furthermore, all of Spirit Airlines' equity award agreements under any incentive plan, and the awards granted pursuant thereto, were extinguished, canceled, and discharged and have no further force or effects.

Issuance of Spirit Equity Securities

On the Effective Date, in connection with 2024 Bankruptcy and in reliance on the exemption from the registration requirements of the Securities Act provided by Section 1145 of the Bankruptcy Code, Spirit issued 7,618,664 shares of

Common Stock and 5,203,899 Warrants to equitize the $410.0 million of then-outstanding Senior Secured Notes and $385.0 million of then-outstanding Convertible Notes.

In addition, on the Effective Date, in connection with the Company’s emergence from the 2024 Bankruptcy and in reliance on the exemption from registration requirements of the Securities Act provided by Section 4(a)(2) of the Securities Act or Regulation S under the Securities Act, based in part on representations made by these certain parties to the Backstop Commitment Agreement, Spirit issued 678,587 shares of Common Stock and 5,670,853 Warrants to specified parties to the Backstop Commitment Agreement dated November 18, 2024. An aggregate of 3,849,442 of such shares of Common Stock and such Warrants were issued for aggregate consideration of $53,892,188.

On December 30, 2024, the Company launched an equity rights offering (the “ERO”) of equity securities of the reorganized Company in an aggregate amount of $350.0 million at a purchase price of $14.00 per share. The final expiration date for the Equity Rights Offering occurred on February 20, 2025. On the emergence of the 2024 Bankruptcy and in reliance on the exemption from the registration requirements of the Securities Act provided by Section 1145 of the Bankruptcy Code, Spirit closed the ERO, issuing 7,770,054 shares of Common Stock and 13,380,504 Warrants to ERO participants, for aggregate consideration of $296,107,812. Refer to Note 4, Emergence from Voluntary Reorganization under the 2024 Chapter 11 Bankruptcy, for additional information.

The Common Stock and the Warrants are described further below under “—Common Stock” and “—Warrants,” respectively.

Registration Rights Agreement

On the Effective Date, holders of the Common Stock who were party to its Backstop Commitment Agreement became party to the Registration Rights Agreement and are entitled to rights with respect to the registration of certain of their shares of Common Stock under the Securities Act.

Warrants

In connection with the Company's emergence from the 2024 Bankruptcy, on the Effective Date, Spirit entered into two warrant agreements with Equiniti Trust Company, LLC as warrant agent (the “Warrant Agreements”) pursuant to which Spirit issued an aggregate of 24,255,256 Warrants for the Common Stock to certain specified investors, consisting of 3,617,385 Warrants issued under a Tranche 1 Warrant Agreement ("the Tranche 1 Warrants") and 20,637,871 Warrants issued under a Tranche 2 Warrant Agreement (the "Tranche 2 Warrants") pursuant to the Plan. Each Warrant entitles the holder to purchase one share of Common Stock for a nominal exercise price of $0.0001 per Warrant. During the nine months ended September 30, 2025, 10.7 million Warrants were exercised and converted into shares of the Company's Common Stock.

Duration and Exercise Price. Each Warrant has an initial exercise price equal to $0.0001 per share of Common Stock. The Tranche 1 Warrants were immediately exercisable, and the Tranche 2 Warrants are exercisable at any time after the date on which the Common Stock is first listed on a securities exchange, which occurred on April 29, 2025. All Warrants may be exercised at any time until such Warrants are exercised in full. The exercise price and number of shares issuable upon exercise are subject to appropriate proportional adjustment in the event of certain dividends, subdivisions or combinations of the Company's Common Stock, or similar events affecting the Company's Common Stock and the exercise price.

Exercisability. A holder may not exercise any portion of its Warrants to the extent that the holder, together with its affiliates and any other persons acting as a group together with any such persons, would own more than 9.9% of the number of shares of Common Stock outstanding immediately after exercise (the “Beneficial Ownership Limitation”) calculated in accordance with Section 13(d) of the Exchange Act. Upon not less than sixty-one (61) days advance written notice to the Company at any time or from time to time, a holder in its sole discretion, may exempt itself from the Beneficial Ownership Limitation. However, under any circumstance, a holder may not exercise the Warrant if such exercise would cause such holder’s beneficial ownership (as defined by Section 13(d) of the Exchange Act) of the Common Stock to exceed 19.9% of its total issued and outstanding Common Stock.

Cashless Exercise. The Warrants may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the holder shall be entitled to receive upon such exercise (either in whole or in part) the net number of shares of Common Stock determined according to a formula set forth in the Warrant Agreements.

Fractional Shares. No fractional shares of Common Stock will be issued upon the exercise of the Warrants and no cash will be distributed in lieu of the issuance of such fractional shares. If more than one Warrant is presented for exercise in full at

the same time by the same holder, the full number of shares of Common Stock that will be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of shares of Common Stock purchasable on exercise of the Warrants so presented. If any fraction of a share of Common Stock or other security deliverable upon proper exercise of the Warrant (a "Warrant Share") would, except pursuant to the Warrant, be issuable on the exercise of any Warrants (or specified portion thereof), as applicable, such Warrant Share shall be rounded up to the next highest whole number.

Transferability. Subject to applicable laws, a Warrant may be transferred at the option of the holder upon surrender of the Warrant to Spirit together with the appropriate instruments of transfer and funds sufficient to pay any transfer taxes payable upon such transfer.

Trading Market. There is no trading market available for the Warrants on any securities exchange or nationally recognized trading system. Spirit does not intend to list the Warrants on any securities exchange or nationally recognized trading system.

Rights as a Stockholder. Except as otherwise provided in the Warrants or by virtue of such holder’s ownership of shares of Common Stock, the holders of the Warrants do not have the rights or privileges of holders of the Company's Common Stock, including any voting rights, until they exercise their Warrants.

Fundamental Transaction. In the event of a fundamental transaction, as described in the Warrants and generally including any reorganization, recapitalization or reclassification of the shares of Common Stock, the sale, transfer or other disposition of all or substantially all of its properties or assets, the Spirit's consolidation or merger with or into another person, the holders of the Warrants will be entitled to receive upon exercise of the Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Warrants immediately prior to such fundamental transaction.

Rights to Dividends and Distributions on Common Stock. Holders of the Tranche 1 Warrants are entitled to dividends and other distributions on Common Stock that such holder would have received had the Warrants been exercised. Such distributions to holders of Tranche 1 Warrants will be made simultaneously with the distribution to holders of Common Stock. Tranche 2 Warrants are not entitled to dividends and other distributions on Common Stock.

In addition, the Tranche 2 Warrant Agreement provides that the shares of Common Stock issuable upon exercise of Tranche 2 Warrants shall be subject to the limitations on ownership by non-U.S. citizens as set forth in the Charter (as defined below).

Exchange Rights of Holders of Tranche 2 Warrants. Holders of Tranche 2 Warrants may exchange such Tranche 2 Warrants for Tranche 1 Warrants in accordance with the Warrant Agreements.

Accounting Policy. The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480, Distinguishing Liabilities from Equity (ASC 480) and ASC 815, Derivatives and Hedging (ASC 815). The assessment considers whether the warrants (i) are freestanding financial instruments pursuant to ASC 480, (ii) meet the definition of a liability pursuant to ASC 480, and (iii) meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company's own stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. For warrants that meet all criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital, on the condensed consolidated statements of stockholders’ deficit at the time of issuance.

The Company concluded that the Warrant Agreements are classified as equity, recorded at fair value upon issuance within the Company’s condensed consolidated balance sheets. On the Emergence Date, the Warrants were valued based on the derived Successor Equity Value detailed in Note 5, Fresh Start Accounting - 2024 Bankruptcy, at issuance. Equity-classified contracts are initially measured and recorded at fair value; subsequent changes in fair value are not recognized as long as the contract continues to be classified as equity. The Company recorded $441.7 million, net of issuance costs, in additional paid-in-capital ("APIC"), related to the fair value of the warrants issued.

Common Stock

Pursuant to the 2024 Bankruptcy's Plan of Reorganization, Spirit amended and restated its certificate of incorporation (the “Charter”) and bylaws (the “Bylaws”), each of which became effective on the Effective Date.

The Charter authorizes Spirit to issue up to 400,000,000 shares of Common Stock.

Dividend Rights. Subject to the rights of holders of any series of then outstanding preferred stock and the limitations under the Delaware General Corporation Law ("DGCL"), each holder of Common Stock has equal rights of participation in the dividends in cash, stock, or property of Spirit, when, as and if the Board declare such dividends from time to time out of assets or funds legally available.

Voting Rights. Each holder of the Company's Common Stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. The holders of Common Stock exclusively possess all voting power; provided, however, that as except as otherwise required by law, holders of Common Stock are not entitled to vote on any amendment to the Charter (or on any amendment to a certificate of designations of any series of preferred stock) that alters or changes the powers, preferences, rights or other terms of one or more outstanding series of preferred stock if the holders of such affected series of preferred stock are entitled to vote, either separately or together with the holders of one or more other such series, on such amendment pursuant to the Charter (or pursuant to a certificate of designations of any series of preferred stock) or pursuant to the DGCL. Spirit's stockholders are not entitled to cumulative voting.

Liquidation. Subject to the rights of holders of any series of then outstanding preferred stock, each holder of Common Stock has equal rights to receive the assets and funds of Spirit available for distribution to stockholders in the event of any liquidation, dissolution, or winding up of the affairs of Spirit, whether voluntary or involuntary.

Rights and Preferences. Holders of Common Stock have no preemptive, conversion, subscription or other rights, and there are no redemption or sinking fund provisions applicable to Common Stock. The rights, preferences and privileges of the holders of Common Stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of Spirit's preferred stock that Spirit may designate in the future.

Limited Voting by Foreign Owners. To comply with restrictions imposed by federal law on foreign ownership of U.S. airlines, the Charter restricts voting of shares of its capital stock by non-U.S. citizens. The restrictions imposed by federal law currently require that no more than 25% of Spirit's voting stock be voted, directly or indirectly, by persons who are not U.S. citizens, and that its president and at least two-thirds of the members of the Board and senior management be U.S. citizens. The Charter provides that no shares of its capital stock may be voted by or at the direction of non-U.S. citizens unless such shares are registered on a separate stock record, which it refers to as the foreign stock record. The Charter further provides that no shares of its capital stock will be registered on the foreign stock record if the amount so registered would exceed the foreign ownership restrictions imposed by federal law.
