The statement on Schedule 13D originally filed with the Securities and Exchange Commission (the “SEC”) by the Reporting Person, Mr. Gregory B.

This amended statement on Schedule 13D/A (this “Amendment”) constitutes Amendment No. 6 to the Schedule 13D. This Amendment is the final amendment to the Schedule 13D and an exit filing for the Reporting Person. Capitalized terms not defined herein have the meanings given to such terms in the Schedule 13D. Except as set forth herein, the Schedule 13D is unmodified.

Item 4. Purpose of the Transaction.

The information contained in Item 4 of the Schedule 13D is hereby amended to add the following information at the end of such Item:

On December 18, 2020, Liberty Broadband Corporation (“Liberty Broadband”) completed its previously announced combination (the “Combination”) with the Issuer, which was effected by (i) a merger of Grizzly Merger Sub 2, Inc. (“Merger Sub”), a Delaware corporation and wholly owned subsidiary of Grizzly Merger Sub 1, LLC (“Merger LLC”), with and into the Issuer (the “Merger”) with the Issuer surviving as an indirect wholly owned subsidiary of Liberty Broadband and (ii) the merger of the Issuer (as the surviving corporation in the Merger) with and into Merger LLC (the “Upstream Merger”), with Merger LLC surviving the Upstream Merger as a wholly owned subsidiary of Liberty Broadband. In accordance with the terms and conditions of the Agreement and Plan of Merger (the “Merger Agreement”), dated as August 6, 2020, by and among Liberty Broadband, Merger LLC, Merger Sub and the Issuer, (i) each share of Series A Common Stock issued and outstanding immediately prior to the effective time of the Merger (the “Effective Time”) (except for shares held by GCI Liberty as treasury stock) was converted into the right to receive 0.580 of a share of Series C common stock, par value $0.01 per share, of Liberty Broadband (the “LBRD Series C Common Stock”) (the “Series A Consideration”) and (ii) each share of Series B Common Stock issued and outstanding immediately prior to the Effective Time (except for shares held by GCI Liberty as treasury stock and for shares of Series B Common Stock to which the holder thereof properly demands and does not withdraw its demand for or otherwise lose its right to, appraisal of such shares) was converted into the right to receive 0.580 of a share of Series B common stock, par value $0.01 per share, of Liberty Broadband (the “LBRD Series B Common Stock”) (the “Series B Consideration” and, together with the Series A Consideration, the “Common Consideration”), and (iii) each share of Series A Cumulative Redeemable Preferred Stock, par value $0.01 per share, of GCI Liberty (“Preferred Stock”) issued and outstanding immediately prior to the Effective Time (except for shares held by GCI Liberty as treasury stock) was converted into the right to receive one share of newly-issued Series A Cumulative Redeemable Preferred Stock, par value $0.01 per share, of Liberty Broadband (the “LBRD Preferred Stock”) (the “Preferred Consideration” and, together with the Common Consideration, the “Merger Consideration”). Prior to the consummation of the Merger, without giving effect to the transactions described in Item 5(c) below, the Reporting Person beneficially owned approximately 1.2% of the outstanding shares of Series A Common Stock and approximately 26.9% of the outstanding shares of Series B Common Stock as calculated in accordance with Rule 13d-3 under the Securities Exchange Act of 1934, as amended, after adjustment for the assumed exercise of all options and other rights to acquire shares of Common Stock held by Mr. Maffei and exercisable within 60 days after December 18, 2020. No fractional shares of LBRD Series C Common Stock or LBRD Series B Common Stock were issued in the Combination. Cash will be paid in lieu of fractional shares as described in the joint proxy statement/prospectus forming a part of Amendment No. 2 to Liberty Broadband’s Registration Statement on Form S-4, filed with the Securities and Exchange Commission on October 30, 2020.

Item 5. Interest in Securities of the Issuer.

The information contained in Item 5 of the Schedule 13D is hereby amended and restated in its entirety to read as follows:

(a) Mr. Maffei beneficially owns no shares of Series A Common Stock or Series B Common Stock.

(b) Not applicable.

(c) As previously disclosed in the Schedule 13D, Mr. Maffei agreed to and did convert each outstanding share of Series B Common Stock he beneficially owned immediately prior to the Effective Time into one share of Series A Common Stock. Except as provided in this Amendment, Mr. Maffei has not effected any other transactions with respect to the Common Stock since Amendment No. 5 to the Statement on Schedule 13D was filed with the SEC on November 30, 2020.

(d) Not Applicable.

(e) Mr. Maffei ceased to be the beneficial owner of more than five percent of the Series A Common Stock and Series B Common Stock on December 18, 2020.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

The information contained in Item 6 of the Schedule 13D is hereby amended to add the following information at the end of such Item:

On December 18, 2020, Liberty Broadband completed its previously announced Combination with the Issuer, which was effected by the Merger and the Upstream Merger. As a result, all shares of Common Stock beneficially owned by the Reporting Person were converted into the right to receive the Merger Consideration subject to the terms and conditions of the Merger Agreement.
