As previously reported, on April 20,
2020, United Airlines Holdings, Inc. (“UAL” and, together with United Airlines, Inc., the “Company”)
entered into a warrant agreement with the United States Department of the Treasury (“Treasury”) in connection with
the Payroll Support Program established under the Coronavirus Aid, Relief, and Economic Security Act (the “PSP Warrant Agreement”).
Pursuant to the PSP Warrant Agreement, UAL has issued to Treasury warrants to purchase up to 4,763,841 shares of common stock (the
“PSP Warrants”). The PSP Warrant Agreement entitles Treasury to customary registration rights.
Also as previously reported, on June 15,
2020, UAL entered into an equity distribution agreement (the “Distribution Agreement”) with Citigroup Global Markets
Inc., BofA Securities, Inc. and J.P. Morgan Securities LLC (collectively, the “Managers”), relating to the issuance
and sale from time to time by UAL, through the Managers, of up to 28,000,000 shares of UAL’s common stock, par value $0.01
per share (the “ATM Shares”). Sales of the ATM Shares, if any, under the Distribution Agreement may be made in any
transactions that are deemed to be “at the market offerings” as defined in Rule 415 under the Securities Act of
1933, as amended. Under the terms of the Distribution Agreement, UAL may also sell ATM Shares to any Manager, as principal for
its own account, at a price agreed upon at the time of sale. If UAL sells ATM Shares to a Manager as principal, UAL will enter
into a separate terms agreement with such Manager.
On November 17, 2020, the Company filed
a shelf registration statement on Form S-3 (File No. 333-250153) (the “Registration Statement”). The Registration
Statement provides for the sale of securities, including shares of common stock and warrants of the Company, from time to time
by UAL, its wholly-owned subsidiary United Airlines, Inc. and selling security holders who may be named in a prospectus supplement.
On the date hereof, UAL filed (i) a prospectus supplement providing for the sale of the remaining 25,322,567 of the ATM Shares
(the “ATM Securities”) and (ii) a prospectus supplement providing for the resale of the PSP Warrants by one or
more selling security holders from time to time, as well as the resale of up to 4,763,841 shares of common stock issuable upon
exercise of such PSP Warrants (collectively, the “Warrant Securities”).
