INFORMATION REQUIRED IN REGISTRATION STATEMENT

On December 4, 2020, the board of directors (the “Board”) of United Airlines Holdings, Inc., a Delaware corporation (the “Company”), adopted a tax benefits preservation plan and declared a dividend of one right (a “Right”) for each outstanding share of Company common stock, par value $0.01 per share (“Common Stock”), to stockholders of record at the close of business on December 14, 2020 (the “Record Date”). Each Right entitles its holder, under the circumstances described below, to purchase from the Company one one-thousandth of a share of Series A Junior Participating Serial Preferred Stock, without par value (“Preferred Stock”), of the Company at an exercise price of $250.00 per Right, subject to adjustment. The description and terms of the Rights are set forth in the tax benefits preservation plan, dated as of December 4, 2020 (the “Tax Benefits Preservation Plan”), between the Company and Computershare Trust Company, N.A., as rights agent (and any successor rights agent, the “Rights Agent”).

The Company adopted the Tax Benefits Preservation Plan in order to protect against a possible limitation on the Company’s ability to use its net operating losses (the “NOLs”) and certain other tax attributes to reduce potential future U.S. federal income tax obligations. The NOLs and certain other tax attributes are valuable assets to the Company, which may inure to the benefit of the Company and its stockholders. However, if the Company experiences an “ownership change,” as defined in Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), its ability to fully utilize the NOLs and certain other tax attributes will be substantially limited and the timing of the usage of the NOLs and other tax attributes could be substantially delayed, which could significantly impair the value of those assets. Generally, an “ownership change” occurs if the percentage of the Company’s stock owned by one or more of its “5-percent shareholders” (as such term is defined in Section 382 of the Code) increases by more than 50 percentage points over the lowest percentage of stock owned by such stockholder or stockholders at any time over a three-year period. The Tax Benefits Preservation Plan is intended to prevent against such an “ownership change” by deterring any person or group, together with its affiliates and associates, from acquiring beneficial ownership of 4.9% or more of the Company’s securities.

The Tax Benefits Preservation Plan should not interfere with any merger or other business combination approved by the Board.

The Rights. The Rights will attach to any shares of Common Stock that become outstanding after the Record Date and prior to the earlier of the Distribution Time (as defined below) and the Expiration Time (as defined below), and in certain other circumstances described in the Tax Benefits Preservation Plan.

Until the Distribution Time, the Rights are associated with Common Stock and evidenced by Common Stock certificates or, in the case of uncertificated shares of Common Stock, the book-entry account that evidences record ownership of such shares, which will contain a notation incorporating the Tax Benefits Preservation Plan by reference, and the Rights are transferable with and only with the underlying shares of Common Stock.

Until the Distribution Time, the surrender for transfer of any shares of Common Stock will also constitute the transfer of the Rights associated with those shares. As soon as practicable after the Distribution Time, separate rights certificates will be mailed to holders of record of Common Stock as of the Distribution Time. From and after the Distribution Time, the separate rights certificates alone will represent the Rights.

The Rights are not exercisable until the Distribution Time. Until a Right is exercised, its holder will have no rights as a stockholder of the Company, including the right to vote or to receive dividends.

Separation and Distribution of Rights; Exercisability. Subject to certain exceptions, the Rights become exercisable and trade separately from Common Stock only upon the “Distribution Time,” which occurs upon the earlier of:

The Board may determine that any person is an Acquiring Person if such person becomes the beneficial owner of 4.9% of the then-outstanding shares of Common Stock under the regulations promulgated under the Code.

An Acquiring Person does not include:

In addition, the Tax Benefits Preservation Plan provides that no person or group will become an Acquiring Person as a result of share purchases or issuances directly from the Company or through an underwritten offering approved by the Board. Also, a person or group will not be an Acquiring Person if the Board determines that such person or group has become an Acquiring Person inadvertently and such person or group as promptly as practicable divests a sufficient number of shares so that such person or group would no longer be an Acquiring Person. There are also certain exceptions for an “investment advisor” to mutual funds or a trustee of trusts qualified under Section 401(a) of the Code sponsored by unrelated corporations, unless the Board determines, in its reasonable discretion, that such investment advisor or trustee is deemed to beneficially own 4.9% or more of the shares of Common Stock then outstanding under specified regulations promulgated under the Code.

Certain synthetic interests in securities created by derivative positions, whether or not such interests are considered to be ownership of the underlying Common Stock or are reportable for purposes of Regulation 13D of the Securities Exchange Act of 1934, as amended, are treated as beneficial ownership of the number of shares of Common Stock equivalent to the economic exposure created by the derivative position, to the extent actual shares of Common Stock are directly or indirectly held by counterparties to the derivatives contracts. In addition, for purposes of the Tax Benefits Preservation Plan, a person or group is deemed to beneficially own shares that such person is deemed to directly, indirectly or constructively own (as determined for purposes of Section 382 of the Code or the regulations promulgated under the Code), and Warrants and Warrant Shares (as each is defined in the Warrant Agreement, dated as of April 20, 2020, between the Company and the United States Department of the Treasury and the Warrant Agreement, dated as of September 28, 2020, between the Company and the United States Department of the Treasury) are disregarded for purposes of determining beneficial ownership.

Expiration Time. The Rights will expire on the earliest to occur of (a) the close of business on December 4, 2023 (the “Final Expiration Time”), (b) the time at which the Rights are redeemed or exchanged by the Company (as described below), (c) the close of business on the first business day following the certification of the voting results of the Company’s 2021 annual meeting of stockholders, if stockholder approval of the Tax Benefits Preservation Plan has not been obtained at such meeting, (d) upon the closing of any merger or other acquisition transaction involving the Company pursuant to a merger or other acquisition agreement that has been approved by the Board before any person or group becomes an Acquiring Person or (e) the time at which the Board determines that the NOLs and certain other tax attributes are utilized in all material respects or that an ownership change under Section 382 of the Code would not adversely impact in any material respect the time period in which the Company could use the NOLs and other tax attributes or materially impair the amount of NOLs and other tax attributes that could be used by the Company in any particular time period, for applicable tax purposes (the earliest of (a), (b), (c), (d) and (e) being herein referred to as the “Expiration Time”).

Flip-in Event. In the event that any person or group (other than certain exempt persons) becomes an Acquiring Person (a “Flip-in Event”), each holder of a Right (other than such Acquiring Person, any of its affiliates or associates or certain transferees of such Acquiring Person or of any such affiliate or associate, whose Rights automatically become null and void) will have the right to receive, upon exercise, Common Stock having a value equal to two times the exercise price of the Right.

For example, at an exercise price of $250.00 per Right, each Right not owned by an Acquiring Person (or by certain related parties) following a Flip-in Event would entitle its holder to purchase $500.00 worth of Common Stock for $250.00. Assuming that Common Stock had a per share value of $50.00 at that time, the holder of each valid Right would be entitled to purchase ten shares of Common Stock for $250.00.

Flip-over Event. In the event that, at any time following the Stock Acquisition Date, any of the following occurs (each, a “Flip-over Event”):

each holder of a Right (except Rights which previously have been voided as described above) will have the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the exercise price of the Right.

Preferred Stock Provisions. Each share of Preferred Stock, if issued: will not be redeemable, will entitle the holder thereof, when, as and if declared, to quarterly dividend payments equal to the greater of $1,000 per share and 1,000 times the amount of all cash dividends plus 1,000 times the amount of non-cash dividends or other distributions paid on one share of Common Stock, will entitle the holder thereof to receive $1,000 plus accrued and unpaid dividends per share upon liquidation and, if shares of Common Stock are exchanged via merger, consolidation or a similar transaction, will entitle the holder thereof to a per share payment equal to the payment made on 1,000 shares of Common Stock.

Anti-dilution Adjustments. The exercise price payable, and the number of shares of Preferred Stock or other securities or property issuable, upon exercise of the Rights are subject to adjustment from time to time to prevent dilution:

With certain exceptions, no adjustment in the exercise price will be required until cumulative adjustments amount to at least 1% of the exercise price. No fractional shares of Preferred Stock will be issued and, in lieu thereof, an adjustment in cash will be made based on the market price of the Preferred Stock on the last trading day prior to the date of exercise.

Redemption; Exchange. At any time prior to the earlier of (i) the close of business on the tenth (10th) day following the Stock Acquisition Date or (ii) the Final Expiration Time, the Company may redeem the Rights in whole, but not in part, at a price of $0.001 per Right (subject to adjustment and payable in cash, Common Stock or other consideration deemed appropriate by the Board). Immediately upon the action of the Board authorizing any redemption or at such later time as the Board may establish for the effectiveness of the redemption, the Rights will terminate and the only right of the holders of Rights will be to receive the redemption price.

At any time after any Acquiring Person, together with all of its affiliates and associates, becomes the beneficial owner of 50% or more of the outstanding shares of Common Stock, the Company may exchange the Rights (other than Rights owned by the Acquiring Person, any of its affiliates or associates or certain transferees of Acquiring Person or of any such affiliate or associate, whose Rights will have become null and void), in whole or in part, at an exchange ratio of one share of Common Stock, or one one-thousandth of a share of Preferred Stock (or of a share of a class or series of the Company’s preferred stock having equivalent rights, preferences and privileges), per Right (subject to adjustment).

Exemption Requests. A person desiring to either (i) effect a transaction that might result in such person becoming a beneficial owner of 4.9% or more of the then-outstanding shares of Common Stock or (ii) effect a transaction that might result in such person owning additional shares of Common Stock when such person already owns 4.9% or more of the then-outstanding shares of Common Stock may, by following the procedures outlined in the Tax Benefits Preservation Plan, request that the Board determine that such person would not be an Acquiring Person. In such case, the Board may grant the exemption notwithstanding the effect on the Company’s NOLs and other tax attributes, if the Board determines that such approval is in the best interests of the Company. The Board may impose any conditions that it deems reasonable and appropriate in connection with any such determination, including restrictions on the ability of the requesting person to transfer shares acquired by it in the transaction requiring approval.

Amendment of the Tax Benefits Preservation Plan. The Company and the Rights Agent may from time to time amend or supplement the Tax Benefits Preservation Plan without the consent of the holders of the Rights. However, on or after the Stock Acquisition Date, no amendment can materially adversely affect the interests of the holders of the Rights (other than the Acquiring Person, any of its affiliates or associates or certain transferees of Acquiring Person or of any such affiliate or associate).

Miscellaneous. While the distribution of the Rights will not be taxable to stockholders or to the Company, stockholders may, depending upon the circumstances, recognize taxable income in the event that the Rights become exercisable for Common Stock (or other consideration) or for common stock of the acquiring company or in the event of the redemption of the Rights as described above.
