This Amendment No. 2 (this “Amendment”) amends and supplements the Schedule 13D filed by the Reporting Persons, together with Fortress Mosaic Sponsor LLC and Principal Holdings I LP,
on January 21, 2020, as amended and supplemented by Amendment No. 1 thereto filed by the Reporting Persons on February 28, 2020 (the “Original Schedule 13D” and, as further amended and supplemented by this Amendment, the “Schedule 13D”),
relating to the shares of Class A common stock, par value $0.0001 per share (“Common Stock”), of Vivint Smart Home, Inc. (formerly Mosaic Acquisition Corp.), a Delaware corporation (the “Issuer”). Except as specifically provided
herein, this Amendment does not modify any of the information previously reported on the Original Schedule 13D. Capitalized terms not otherwise defined in this Amendment shall have the same meanings ascribed thereto in the Original Schedule

Item 4. Purpose of Transaction.
This Amendment amends and restates the last paragraph under the heading “Sponsor Agreement” in Item 4 of the Original Schedule 13D in
its entirety as follows:
“On January 17, 2020, upon the closing of the merger, 50% of the 5,171,642 shares of Common Stock held by Fortress Sponsor following
the automatic conversion of Founder Shares into Common Stock were unvested, and all of the private placement warrants held by Fortress Sponsor were unvested. On February 26, 2020, a $12.50 Stock Price Level was achieved, resulting in the vesting
of 50% of the unvested shares of Common Stock held by Fortress Sponsor, being 1,292,910.5 newly vested shares of Common Stock, and the vesting of 50% of the unvested private placement warrants held by Fortress Sponsor, being newly vested warrants
to purchase 1,483,333.5 shares of Common Stock. On March 11, 2020, a $15.00 Stock Price Level was achieved, resulting in the vesting of the remaining 50% of the unvested shares of Common Stock held by Fortress Sponsor, being 1,292,910.5 newly
vested shares of Common Stock, and the vesting of the remaining 50% of the unvested private placement warrants held by Fortress Sponsor, being newly vested warrants to purchase 1,483,333.5 shares of Common Stock.”

or incorporated in Items 2, 4 and 6 is incorporated by reference in its entirety into this Item 5.
The following disclosure is based on the 177,901,235 shares of Common Stock outstanding as of March 12, 2020 (adjusted, in respect of

outstanding immediately following the issuance of certain additional shares of Common Stock of the Issuer on March 12, 2020 as a result of the $15.00 Stock Price Level having been achieved, according to the Issuer.
Fortress Investor may be deemed to beneficially own and share the power to vote and dispose of the 17,357,339 shares of Common Stock
directly held by it, which represent 9.8% of the outstanding Common Stock.
