        <footnote id="F1">This transaction reflects the transfer of shares by the John P. Scripps Trust FBO Douglas A. Evans U/A dated 12/28/1984, of which Barbara Victoria Scripps Evans is trustee, to the Douglas A. Evans 2017 Trust dated 8/24/2017, of which the reporting person is trustee.</footnote>
        <footnote id="F2">6,818 of these shares were inadvertently reported as directly held on the reporting person's previously filed Form 4, but such shares were contributed on October 11, 2017 to the Douglas A. Evans 2017 Trust dated 8/24/2017, of which the reporting person is trustee.</footnote>
        <footnote id="F3">These shares are owned directly by the Douglas A. Evans 2017 Trust dated 8/24/2017 and indirectly by Douglas A. Evans, as trustee of the Douglas A. Evans 2017 Trust dated 8/24/2107.</footnote>
    </footnotes>

    <remarks>The reporting person may be deemed to have shared voting power with respect to more than 10% of the Class A Common Shares of the Issuer (due solely to the convertibility of Common Voting Shares of the Company into Class A Common Shares on a share-for-share basis) due to the voting provisions of the Amended and Restated Scripps Family Agreement dated May 19, 2015, as amended on March 29, 2017, to which the reporting person is a party. The reporting person filed a Schedule 13D with the Commission on January 24, 2013, as last amended on August 22, 2018.</remarks>
