Item 1.01    Entry into a Material Definitive Agreement.

Amendment to Merger Agreement

On June 24, 2022, Spirit Airlines, Inc., a Delaware corporation (“Spirit”), Frontier Group Holdings, Inc., a Delaware corporation (“Frontier”), and Top Gun Acquisition Corp., a Delaware corporation and a direct, wholly owned subsidiary of Frontier ( “Merger Sub”), entered into Amendment No. 2 (the “Second Amendment”) to the Agreement and Plan of Merger, dated as of February 5, 2022 (as previously amended, the “Merger Agreement”), by and among Spirit, Frontier and Merger Sub, pursuant to which and subject to the terms and conditions therein, Merger Sub will merge with and into Spirit, with Spirit continuing as the surviving entity (the “Merger”).

The Second Amendment amends the Merger Agreement to increase the amount of the cash consideration payable to Spirit stockholders by an additional $2.00 per share, for an aggregate cash amount, without interest, equal to $4.13 per share of Spirit common stock, minus, to the extent paid or payable, the $2.22 per share dividend described in the following paragraph (the “Per Share Cash Consideration”).

The Second Amendment also provides that, following a Spirit stockholder vote in favor of the Merger Agreement, a portion of the cash consideration will be paid in advance in the form of a cash dividend to Spirit stockholders as of a record date to be determined (the “Prepayment Dividend”) equal to $2.22 per share of Spirit common stock (the “Prepayment Dividend Amount”) on October 3, 2022, or any other date determined by Spirit and consistent with applicable law (the “Dividend Payment Date”). Frontier will make a non-interest bearing loan to Spirit in an amount equal to $241,100,000 in connection with the dividend. In the event that the Merger Agreement is terminated and the reverse termination fee is payable, the amount of this loan would be offset against the reverse termination fee owed by Frontier to Spirit.

The Second Amendment also provides that outstanding Spirit restricted stock units (including Spirit performance market stock units) and Spirit performance share awards granted in fiscal year 2022 will be converted into the right to receive a Frontier restricted stock unit award and an amount of cash equal to the sum of (x) the Per Share Cash Consideration and (y) the Prepayment Dividend Amount, solely to the extent the Prepayment Dividend has been paid or is payable to Spirit stockholders and no adjustment or payment has been made in respect of the related Spirit equity awards prior to the closing under the Spirit equity award plan to reflect the Prepayment Dividend. Further, Spirit performance share awards granted prior to fiscal year 2022 will entitle each holder to receive the number of shares of Spirit common stock that are earned based on target performance as of immediately prior to the closing, pro-rated based on the number of whole months elapsed from the first day of the applicable performance period until the closing date, with any such shares of Spirit common stock so delivered converted into the right to receive an amount of cash equal to the sum of (x) the Per Share Cash Consideration and (y) the Prepayment Dividend Amount, solely to the extent the Prepayment Dividend has been paid or is payable to Spirit stockholders and no adjustment or payment has been made in respect of the related Spirit performance share award prior to the closing under the Spirit equity award plan to reflect the Prepayment Dividend. Further, any outstanding Spirit restricted stock units (including performance market stock units), Spirit performance share awards granted prior to fiscal year 2022 or Spirit performance share awards granted in fiscal year 2022 that vest during the period commencing on the Dividend Payment Date and ending on the day immediately prior to the closing date shall receive an amount of cash equal to the Prepayment Dividend Amount upon the vesting of such equity awards, provided that no adjustment or payment has been made in respect of the related Spirit equity awards prior to the closing under the Spirit equity award plan to reflect the Prepayment Dividend.

The Second Amendment also increases the reverse termination fee payable by Frontier to $350,000,000.

The Second Amendment also increases the number of board seats of the combined company to be determined by the board of directors of Frontier by one and decreases the number of board seats of the combined company to be determined by the board of directors of Spirit by one.

Except as modified by the Second Amendment, the terms of the Merger Agreement in the form filed by Spirit as Exhibit 2.1 to the Current Report on Form 8-K filed by Spirit on February 7, 2022 with the U.S. Securities and Exchange Commission (“SEC”), as amended by the Amendment to the Agreement and Plan of Merger, dated June 2, 2022, by and among Spirit, Frontier and Merger Sub, are unchanged.

The foregoing description of the Second Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Second Amendment, which is attached hereto as Exhibit 2.1 and is incorporated by reference herein.

communication and attributable to Frontier, Spirit, JetBlue or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this communication.

Actual results could differ materially from these forward-looking statements due to numerous factors including, without limitation, the following: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the Merger Agreement; failure to obtain applicable regulatory or Spirit stockholder approval in a timely manner or otherwise and the potential financial consequences thereof; failure to satisfy other closing conditions to the proposed transactions; failure of the parties to consummate the transaction; risks that the new businesses will not be integrated successfully or that the combined companies will not realize estimated cost savings, value of certain tax assets, synergies and growth, or that such benefits may take longer to realize than expected; failure to realize anticipated benefits of the combined operations; risks relating to unanticipated costs of integration; demand for the combined company’s services; the growth, change and competitive landscape of the markets in which the combined company participates; expected seasonality trends; diversion of managements’ attention from ongoing business operations and opportunities; potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the transaction; risks related to investor and rating agency perceptions of each of the parties and their respective business, operations, financial condition and the industry in which they operate; risks related to the potential impact of general economic, political and market factors on the companies or the proposed transaction; that Frontier’s cash and cash equivalents balances, together with the availability under certain credit facilities made available to Frontier and certain of its subsidiaries under its existing credit agreements, will be sufficient to fund Frontier’s operations including capital expenditures over the next 12 months; Frontier’s expectation that based on the information presently known to management, the potential liability related to Frontier’s current litigation will not have a material adverse effect on its financial condition, cash flows or results of operations; that the COVID-19 pandemic will continue to impact the businesses of the companies; ongoing and increase in costs related to IT network security; the outcome of any discussions between JetBlue and Spirit with respect to a possible transaction, including the possibility that the parties will not agree to pursue a business combination transaction or that the terms of any such transaction will be materially different from those described herein; the conditions to the completion of the possible transaction, including the receipt of any required stockholder and regulatory approvals and, in particular, the companies’ expectation as to the likelihood of receipt of antitrust approvals; JetBlue’s ability to finance the possible transaction and the indebtedness JetBlue expects to incur in connection with the possible transaction; the possibility that JetBlue may be unable to achieve expected synergies and operating efficiencies within the expected timeframes or at all and to successfully integrate Spirit’s operations with those of JetBlue, and the possibility that such integration may be more difficult, time-consuming or costly than expected or that operating costs and business disruption (including, without limitation, disruptions in relationships with employees, customers or suppliers) may be greater than expected in connection with the possible transaction; and other risks and uncertainties set forth from time to time under the sections captioned “Risk Factors” in Frontier’s, Spirit’s and JetBlue’s reports and other documents filed with the SEC from time to time, including their Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q.

Conversion of Securities in the Merger. Section 2.1(a) of the Merger Agreement is hereby amended to delete clause (i) of the first sentence thereof in its entirety and substitute therefor: “(i) an amount in cash, without interest, equal to (x) $4.13 minus (y) to the extent paid pursuant to Section 5.19(a) (or, in the event that the Closing Date occurs after the record date for the Prepayment Dividend but before the Dividend Payment Date, to the extent payable after the Closing Date pursuant to Section 5.19(a)), the Prepayment Dividend Amount (the “Per Share Cash Consideration”) and” 2. Treatment of Company Equity Awards; Stock Plans. (a) Section 2.5(a) of the Merger Agreement is hereby amended and restated to read in its entirety as follows with deleted language indicated by strikethrough and newly added language indicated by double underlining: (a) Treatment of Company RSU Awards. Effective as of immediately prior to the Effective Time, each outstanding award of restricted stock units (other than Company Performance Share Awards and 2022 Company Performance Share Awards, but including, for clarity, performance market stock unit awards denominated in Company Common Stock granted pursuant to any Company Equity Award Plan (each, a “Company

2 1007950653v2 MSU Award”)) denominated in Company Common Stock granted pursuant to any Company Equity Award Plan (each, a “Company RSU Award”), shall be assumed by Parent and converted into (i) for each share of Company Common Stock underlying the related Company RSU Award as of immediately prior to the Effective Time (treating for this purpose any performance-based vesting condition to which a Company MSU Award is subject as having been achieved based on target performance as of immediately prior to the Effective Time), the right to receive an amount of cash equal to the sum of (x) the Per Share Cash Consideration plus (y) solely to the extent (1) the related Company RSU Award has not been otherwise equitably or discretionarily adjusted under Section 14.2 of the Company Equity Award Plan and no amount has been otherwise paid in respect of the related Company RSU Award to the holder thereof under Section 14.2 of the Company Equity Award Plan, in each case, to reflect the Prepayment Dividend, and (2) paid pursuant to Section 5.19(a) (or, in the event that the Closing Date occurs after the record date for the Prepayment Dividend but before the Dividend Payment Date, to the extent payable after the Closing Date pursuant to Section 5.19(a)), the Prepayment Dividend Amount, which cash will be subject to the same vesting schedule applicable to the related Company RSU Award, and (ii) a Parent restricted stock unit award (a “Parent RSU Award”) denominated in Parent Common Stock in accordance with this Section 2.5(a).

Any Shares so delivered in respect of Company Performance Share Awards shall be deemed to be issued and outstanding as of immediately prior to the Effective Time and treated in accordance with Section 2.1(a), provided that solely to the extent (i) the related Company Performance Share Award has not been otherwise equitably or discretionarily adjusted under Section 14.2 of the Company Equity Award Plan and no amount has been otherwise paid in respect of the related Company Performance Share Award to the holder thereof under Section 14.2 of the Company Equity Award Plan, in each case, to reflect the Prepayment Dividend and (ii) the Prepayment Dividend Amount was paid pursuant to Section 5.19(a) (or, in the event that the Closing Date occurs after the record date for the Prepayment Dividend but before the Dividend Payment Date, to the extent the Prepayment Dividend Amount is payable after the Closing Date pursuant to Section 5.19(a)), the holder of each such share shall be entitled to receive the Prepayment Dividend Amount in addition to the Per Share Cash Consideration.

(d) Section 2.5(e) of the Merger Agreement is hereby amended and restated to read in its entirety as follows with deleted language indicated by strikethrough and newly added language indicated by double underlining: (e) Corporate Actions. At or prior to the Effective Time, the Company, Parent, the Company Board (or a duly authorized committee thereof) and the Parent Board (or a duly authorized committee thereof), as applicable, shall adopt any resolutions and take any actions which are necessary to effectuate the provisions of this Section 2.5.

At or prior to the Dividend Payment Date, the Company Board (or a duly authorized committee therof) shall adopt any resolutions and take any actions to ensure that each outstanding Company RSU Award, Company Performance Share Award or 2022 Company Performance Share Award that vests during the period commencing on the Dividend Payment Date through the day immediately prior to the Closing Date shall receive an amount of cash equal to the Prepayment Dividend Amount upon the vesting of such equity award (provided that solely to the extent the related Company RSU Award, Company Performance Share Award or 2022 Company Performance Share Award has not been otherwise equitably or discretionarily adjusted under Section 14.2 of the Company Equity Award Plan). 3. Governance Matters.
