Introductory Note

On December 14, 2016, pursuant to the Agreement and Plan of Merger (the “Merger Agreement”), dated as of April 1, 2016, by and among Virgin America Inc., a Delaware corporation (“Virgin America” or the “Company”), Alaska Air Group, Inc., a Delaware corporation (“Alaska”), and Alpine Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of Alaska (“Merger Sub”), Merger Sub merged with and into Virgin America, with Virgin America surviving as a direct wholly-owned subsidiary of Alaska (the “Merger”).

The description of the Merger Agreement and the Merger in this Current Report on Form 8-K does not purport to be complete and is subject, and qualified in its entirety by reference, to the full text of the Merger Agreement, which is attached as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on April 4, 2016 and incorporated herein by reference.

The disclosures under the Introductory Note are incorporated herein by reference.

As previously disclosed, the Company entered into a Note Purchase Agreement, dated as of November 19, 2014, by and between Virgin Management Limited, a limited liability company organized under the laws of England and Wales (the “Virgin Group”) and the Company (the “Note Purchase Agreement”), pursuant to which the Company issued to Virgin Group a $50.0 million promissory note bearing interest at a rate of 5.0% per annum, compounded annually (the “Post-IPO Note”). In connection with the Merger, all outstanding amounts under the Post-IPO Note will be paid in full and all commitments and obligations under the Note Purchase Agreement will be terminated and released and will become null and void.

The description of the Note Purchase Agreement and the Post-IPO Note in this Current Report on Form 8-K does not purport to be complete and is subject, and qualified in its entirety by reference, to the full text of the Note Purchase Agreement and the form of Post-IPO Note, which are attached as Exhibit 99.3 to the Company’s Current Report on Form 8-K filed with the SEC on November 19, 2014 and incorporated herein by reference.

The disclosures under the Introductory Note are incorporated herein by reference.

At the effective time of the Merger (the “Effective Time”), each share of Virgin America voting common stock, par value $0.01 per share (the “Voting Common Stock”), and Virgin America non-voting common stock, par value $0.01 per share (the “Non-Voting Common Stock” and, together with the Voting Common Stock, the “Virgin America Common Stock”, and shares of Virgin America Common Stock are hereinafter referred to as the “Shares”) issued and outstanding immediately prior to the Effective Time (other than Shares held by Virgin America, or Alaska or its subsidiaries, including Merger Sub) was converted into the right to receive $57.00 in cash, without interest (the “Merger Consideration”).

Immediately prior to the Effective Time, (i) each unexpired and unexercised option to purchase Shares (each, an “Option”), whether or not then exercisable or vested, vested and was canceled and, in exchange therefor, each holder of any such Option became entitled to receive an amount in cash equal to the product of (A) the total number of Shares subject to such Option and (B) the excess, if any, of the Merger Consideration over the exercise price per Share of such Option; (ii) each outstanding award of Virgin America restricted stock units vested, became free of any restrictions and was canceled in exchange for the right to receive a cash payment equal to the Merger Consideration for each unit subject to the award; and (iii) each outstanding award of Virgin America Common Stock that was subject to restrictions based on performance or continuing service (each, an “RSA”) vested (treating for this purpose any performance-based vesting condition to which such RSA is subject as having been attained at “maximum” level), became free of any restrictions and was converted into the right to receive payment of the Merger Consideration. In each case, such payments were made without interest and subject to deduction for any required tax withholdings.

The aggregate consideration paid to stockholders and other equity holders of Virgin America by Alaska to acquire Virgin America was approximately $2.6 billion, without giving effect to related transaction fees and expenses.

The foregoing description of the Merger and the Merger Agreement is not complete and is subject to, and qualified in its entirety by reference to, the full text of the Merger Agreement, which was filed as Exhibit 2.1 to Virgin America’s Current Report on Form 8-K filed with the SEC on April 4, 2016, and is incorporated herein by reference.

Prior to the Merger, the Shares were registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and listed on The NASDAQ Global Select Market (“NASDAQ”) under the symbol “VA.” Trading of the Shares on NASDAQ was halted before the opening of trading on December 14, 2016 and will be suspended before the opening of trading on December 15, 2016. Virgin America has requested that NASDAQ file a Form 25 with the SEC to withdraw the Shares from listing and terminate the registration of the Shares under Section 12(b) of the Exchange Act. Virgin America also intends to file a Form 15 with the SEC to terminate the registration of the Shares under the Exchange Act and suspend its reporting obligations under Section 15(d) of the Exchange Act.
