On September 23, 2020, the board of directors (the “Board”) of Liberty Broadband Corporation (“Liberty Broadband”) approved the following changes to the Board, subject to and immediately following the completion of the proposed combination (the “Combination”) of Liberty Broadband and GCI Liberty, Inc. (“GCI Liberty”) and the other transactions contemplated by the Agreement and Plan of Merger, dated as of August 6, 2020, by and among Liberty Broadband, GCI Liberty, Grizzly Merger Sub 1, LLC and Grizzly Merger Sub 2, Inc.: (i) the size of the Board will increase from six to eight directorships; (ii) the newly created directorships resulting from such increase will be a Class II directorship and a Class III directorship, with a term expiring at the annual meeting of stockholders in 2022 and 2023, respectively and (iii) Sue Ann R. Hamilton and Gregg L. Engles will be appointed to the Board to fill the newly created directorships and will serve as a Class II director and a Class III director, respectively.

The Board has determined that Ms. Hamilton and Mr. Engles each qualify as an independent director for purposes of the rules of The Nasdaq Stock Market LLC as well as applicable rules and regulations adopted by the Securities and Exchange Commission.

If the Combination is completed and Ms. Hamilton and Mr. Engles are appointed to the Board, it is expected that they will each receive the same compensation as Liberty Broadband’s other nonemployee directors, which is summarized in Liberty Broadband’s proxy statement for the annual meeting of stockholders held on May 19, 2020, which was filed with the Securities and Exchange Commission on April 10, 2020.
