QUESTIONS & ANSWERS

        The following are some questions that you may have regarding the combination, the issuance of shares of Liberty Broadband stock to GCI Liberty stockholders in connection with the combination, and other matters being considered at the Liberty Broadband special meeting of stockholders (the “Liberty Broadband special meeting”) and GCI Liberty special meeting of stockholders (the “GCI Liberty special meeting”) and the answers to those questions. Liberty Broadband and GCI Liberty urge you to carefully read the entirety of this joint proxy statement/prospectus, including the annexes hereto and the information incorporated herein, because the information in this section does not provide all the information that might be important to you with respect to the combination, the issuance of shares of Liberty Broadband stock in connection with the combination, and the other matters being considered at the Liberty Broadband special meeting and the GCI Liberty special meeting.

Q:    What is the combination?

A:

Liberty Broadband Corporation (“Liberty Broadband”), GCI Liberty, Inc. (“GCI Liberty”), Grizzly Merger Sub 1, LLC, a wholly owned subsidiary of Liberty Broadband (“Merger LLC”), and Grizzly Merger Sub 2, Inc., a wholly owned subsidiary of Merger LLC (“Merger Sub”), have entered into an Agreement and Plan of Merger (as may be amended from time to time, the “merger agreement”) that provides for the acquisition of GCI Liberty by Liberty Broadband. Subject to approval of the stockholders of Liberty Broadband and GCI Liberty and the satisfaction or (to the extent permitted) waiver of certain other closing conditions, Liberty Broadband will acquire GCI Liberty through the merger of Merger Sub with and into GCI Liberty, with GCI Liberty surviving the first merger and becoming an indirect wholly owned subsidiary of Liberty Broadband (the “first merger”). Immediately following the first merger, GCI Liberty, as the surviving corporation of the first merger, will merge with and into Merger LLC, with Merger LLC surviving the upstream merger as a wholly owned subsidiary of Liberty Broadband (the “upstream merger,” and, together with the first merger, the “combination”). If the combination is completed, holders of GCI Liberty capital stock (as defined below) will receive the merger consideration, as described further below. The principal terms and conditions of the combination are contained in the merger agreement, which is attached as Annex A to this joint proxy statement/prospectus. We encourage you to read this agreement carefully and in its entirety, as it is the legal document that governs the combination.

In connection with the transactions contemplated by the merger agreement, John C. Malone, the Chairman of the Board of Liberty Broadband and GCI Liberty (“Mr. Malone”), and certain members of the Malone Group (as defined below) have committed to vote all of the shares owned by them, representing approximately 48.3% of the aggregate voting power of Liberty Broadband as of August 31, 2020 and approximately 27.0% of the aggregate voting power of GCI Liberty as of August 31, 2020, in favor of the combination. See “Special Factors—Other Agreements Related to the Combination—Liberty Broadband Voting Agreement” and “Special Factors—Other Agreements Related to the Combination—GCI Liberty Voting Agreement.”

In addition, Liberty Broadband entered into an exchange agreement (the “exchange agreement”) with Mr. Malone and a revocable trust of which Mr. Malone is the sole trustee and beneficiary (the “JCM Trust”), pursuant to which the JCM Trust waived the right to receive shares of Liberty Broadband Series B common stock, par value $0.01 per share (“Liberty Broadband Series B common stock”), in the combination with respect to certain shares of GCI Liberty Series B common stock, par value $0.01 per share (“GCI Liberty Series B common stock”), owned by it and will instead receive an equal number of shares of Liberty Broadband Series C common stock, par value $0.01 per share (“Liberty Broadband Series C common stock”) so that Mr. Malone's aggregate voting power at Liberty Broadband (including shares held in certain trusts not party to the voting agreements (as defined below)) remains at approximately, but would not exceed, 49%

immediately following the effective time (as defined below), which is approximately equal to Mr. Malone's current voting power in Liberty Broadband. Following the effective time, Mr. Malone and the JCM Trust may exchange a number of shares of Liberty Broadband Series C common stock on a one-for-one basis for the waived shares of Liberty Broadband Series B common stock in order to preserve Mr. Malone's target voting power of approximately 49% (subject to reduction in the event of certain transfers by Mr. Malone and the JCM Trust) (“target voting power”) following the occurrence of certain voting dilution events which would result in Mr. Malone's voting power falling below the target voting power less 0.5% and in certain other circumstances. Conversely, following any repurchase, redemption or certain other events that would result in Mr. Malone's voting power exceeding the target voting power plus 0.5%, Mr. Malone and the JCM Trust will be required to transfer shares of Liberty Broadband Series B common stock owned by them to Liberty Broadband in exchange for an equal number of shares of Liberty Broadband Series C common stock, but only as necessary in order to preserve the target voting power. See “Special Factors—Other Agreements Related to the Combination—Exchange Agreement.”

Certain other agreements have been entered into in connection with the combination, including certain joinder agreements, which are described in more detail in “Special Factors—Other Agreements Related to the Combination—Additional Transaction Agreements.”

Q:    Why am I receiving this joint proxy statement/prospectus?

A:

Liberty Broadband and GCI Liberty are sending these materials to their respective stockholders to help them decide how to vote their shares of Liberty Broadband common stock and GCI Liberty capital stock, respectively, with respect to the combination and other matters to be considered at the Liberty Broadband special meeting and the GCI Liberty special meeting.

The combination cannot be completed unless Liberty Broadband stockholders approve the share issuance. Additionally, pursuant to the merger agreement, it is a non-waivable condition that the merger agreement be approved by the affirmative vote of the holders of a majority of the aggregate voting power of the shares of Liberty Broadband common stock outstanding and entitled to vote on the proposal at the Liberty Broadband special meeting, voting together as a single class, excluding all outstanding shares beneficially owned, directly or indirectly, by GCI Liberty and its subsidiaries, Mr. Malone and certain other parties, as described below. Liberty Broadband is holding a special meeting of its stockholders to vote on the proposals necessary to complete the combination. Information about the Liberty Broadband special meeting, the combination, the merger agreement and the other business to be considered by Liberty Broadband stockholders at the Liberty Broadband special meeting is contained in this joint proxy statement/prospectus.

The combination also cannot be completed unless GCI Liberty stockholders approve the adoption of the merger agreement. In addition, pursuant to the merger agreement, it is a non-waivable condition that the merger agreement be approved by the affirmative vote of the holders of a majority of the aggregate voting power of the shares of GCI Liberty capital stock outstanding and entitled to vote on the proposal at the GCI Liberty special meeting, voting together as a single class, excluding all outstanding shares beneficially owned, directly or indirectly, by Liberty Broadband and its subsidiaries, Mr. Malone and certain other parties, as described below. GCI Liberty is holding a special meeting of its stockholders to vote on the proposals necessary to complete the combination. Information about the GCI Liberty special meeting, the combination, the merger agreement and the other business to be considered by GCI Liberty stockholders at the GCI Liberty special meeting is contained in this joint proxy statement/prospectus.

This joint proxy statement/prospectus constitutes both a proxy statement of Liberty Broadband and GCI Liberty and a prospectus of Liberty Broadband. It is a joint proxy statement because the

Liberty Broadband board of directors (the “Liberty Broadband Board”) and the GCI Liberty board of directors (the “GCI Liberty Board”) are soliciting proxies from their respective stockholders. It is a prospectus because Liberty Broadband will issue shares of its capital stock upon the conversion of the outstanding shares of GCI Liberty capital stock in the combination. This joint proxy statement/prospectus includes important information about the combination, the merger agreement and the special meetings. Liberty Broadband stockholders and GCI Liberty stockholders should read this information carefully and in its entirety. The enclosed voting materials allow Liberty Broadband stockholders and GCI Liberty stockholders to vote their shares by proxy without attending the applicable special meeting in person via the Internet.

Q:    When is the Liberty Broadband special meeting?

A:

The Liberty Broadband special meeting will be held at [    ·    ] [a].m., Mountain time, on [    ·    ], 202[    ·    ].

Q:    When is the GCI Liberty special meeting?

A:

The GCI Liberty special meeting will be held at [    ·    ] [a].m., Mountain time, on [    ·    ], 202[    ·    ].

Q:    Will the Liberty Broadband special meeting or GCI Liberty special meeting be held virtually due to concerns about the COVID-19 pandemic?

A:

Yes. To enter the Liberty Broadband special meeting and the GCI Liberty special meeting, Liberty Broadband stockholders and GCI Liberty stockholders will need the 16-digit control number that is printed in the box marked by the arrow on their proxy cards. Each company recommends that its respective stockholders log in at least fifteen minutes before the applicable special meeting to ensure that they are logged in when the meeting starts. Online check-in will start shortly before the meeting on [    ·    ], 202[    ·    ].

Q:    What will GCI Liberty stockholders receive for their shares of GCI Liberty capital stock?

A:

At the effective time of the first merger (the “effective time”):

•

each share of GCI Liberty Series A common stock, par value $0.01 per share (“GCI Liberty Series A common stock”) issued and outstanding immediately prior to the effective time (other than excluded treasury shares (as defined below)) will be converted into the right to receive 0.580 of a share of Liberty Broadband Series C common stock (the “Series A merger consideration”);

•

each share of GCI Liberty Series B common stock issued and outstanding immediately prior to the effective time (other than excluded shares (as defined below)) will be converted into the right to receive 0.580 of a share of Liberty Broadband Series B common stock (the “Series B merger consideration”); and

•

each share of GCI Liberty Series A Cumulative Redeemable Preferred Stock, par value $0.01 per share (“GCI Liberty Preferred Stock,” and together with the GCI Liberty Series A common stock and GCI Liberty Series B common stock, the “GCI Liberty capital stock”) issued and outstanding immediately prior to the effective time (other than excluded treasury shares) will be converted into the right to receive one share of Liberty Broadband Series A Cumulative Redeemable Preferred Stock, par value $0.01 per share (“Liberty Broadband Preferred Stock” or the “preferred merger consideration”).

In lieu of issuing fractional shares of Liberty Broadband Series C common stock and Liberty Broadband Series B common stock that otherwise would be issued as part of the merger

consideration, cash will instead be paid as described later in this joint proxy statement/prospectus. The shares of Liberty Broadband Series C common stock, Liberty Broadband Series B common stock and Liberty Broadband Preferred Stock issuable in exchange for shares of GCI Liberty capital stock and the cash payable in lieu of the fractional shares are referred to as the “merger consideration.” The merger consideration will not be deliverable with respect to (x) shares of GCI Liberty capital stock held by GCI Liberty as treasury stock or by any of GCI Liberty's wholly owned subsidiaries or owned by Liberty Broadband or its wholly owned subsidiaries (the “excluded treasury shares”) or (y) shares of GCI Liberty Series B common stock held by any stockholders who have perfected and have not waived, effectively withdrawn or lost their appraisal rights pursuant to Section 262 of the General Corporation Law of the State of Delaware (collectively with the excluded treasury shares, the “excluded shares”). The 0.580 of a share of Liberty Broadband Series C common stock or Liberty Broadband Series B common stock that is a component of the calculation of the merger consideration is referred to as the “exchange ratio.” Holders of Liberty Broadband Series C common stock are not entitled to any voting powers, except as otherwise required by Delaware law. Holders of Liberty Broadband Series B common stock are entitled to ten votes per share, and holders of Liberty Broadband Preferred Stock will be entitled to one-third of a vote per share. The merger consideration is described in more detail in “Special Factors—The Merger Agreement—Merger Consideration.”

Q:    Will Liberty Broadband issue fractional shares of Liberty Broadband Series C common stock or Liberty Broadband Series B common stock as part of the merger consideration?

A:

Liberty Broadband will not issue fractional shares of Liberty Broadband Series C common stock or Liberty Broadband Series B common stock as part of the merger consideration. To the extent that the combination would result in a GCI Liberty stockholder of record being issued a fractional share, such GCI Liberty stockholder of record will instead receive a cash payment in an amount based on the aggregation and sale of all fractional shares by Liberty Broadband's exchange agent for the combination at prevailing market prices on behalf of such GCI Liberty stockholder. Amounts payable in lieu of such fractional shares will be payable from the proceeds of the aggregation and sale of the fractional shares as soon as practicable following the completion of the combination. No GCI Liberty stockholder will be entitled to dividends, voting rights or any other rights with respect to any fractional shares.

Q:    What happens if the market price of the Liberty Broadband Series C common stock, Liberty Broadband Series B common stock or GCI Liberty capital stock changes before the closing of the combination?

A:

No change will be made to the merger consideration if the market price of Liberty Broadband Series C common stock, Liberty Broadband Series B common stock or GCI Liberty capital stock changes before the combination. Because the exchange ratio is fixed, the value of the consideration to be received by GCI Liberty stockholders in connection with the combination will depend on the market price of Liberty Broadband Series C common stock and Liberty Broadband Series B common stock at the time of the combination.

Although the number of shares of Liberty Broadband Series C common stock and Liberty Broadband Series B common stock that holders of GCI Liberty Series A common stock and GCI Liberty Series B common stock, respectively, will receive is fixed, the market value of Liberty Broadband Series C common stock and Liberty Broadband Series B common stock will fluctuate and will not be known at the time Liberty Broadband stockholders or GCI Liberty stockholders vote to approve the Liberty Broadband stockholder proposals or GCI Liberty stockholder proposals, respectively. Based on the closing price of Liberty Broadband Series C common stock on the Nasdaq Global Select Market and the last sale price of Liberty Broadband Series B

common stock on the OTC Markets, in each case, on June 29, 2020, the last trading day before the public announcement of the merger consideration, the exchange ratio represented approximately $72.49 in value for each share of GCI Liberty Series A common stock and $71.92 in value for each share of GCI Liberty Series B common stock. Based on the closing price of Liberty Broadband Series C common stock on September 10, 2020 and the last sale price of Liberty Broadband Series B common stock on September 4, 2020, which in each case was the last practicable trading day before the date of this joint proxy statement/prospectus, the exchange ratio represented approximately $78.94 in value for each share of GCI Liberty Series A common stock and $80.62 in value for each share of GCI Liberty Series B common stock. We urge you to obtain current market quotations for shares of GCI Liberty capital stock, Liberty Broadband Series C common stock and Liberty Broadband Series B common stock. GCI Liberty Series A common stock and GCI Liberty Preferred Stock are each listed on the Nasdaq Global Select Market under the symbols “GLIBA” and “GLIBP,” respectively, and GCI Liberty Series B common stock is quoted on the OTC Markets under the symbol “GLIBB,” but it is not actively traded. Liberty Broadband Series C common stock trades on the Nasdaq Global Select Market under the symbol “LBRDK,” and Liberty Broadband Series B common stock is quoted on the OTC Markets under the symbol “LBRDB,” but it is not actively traded. The Liberty Broadband Preferred Stock to be issued in connection with the combination will have been authorized for listing on Nasdaq under the symbol “LBRDP,” subject to official notice of issuance, on or before the closing of the combination.

Q:    What equity stake will GCI Liberty stockholders hold in Liberty Broadband immediately following the combination?

A:

Upon the effective time, based solely on their ownership of GCI Liberty capital stock and excluding any shares of Liberty Broadband common stock held by such stockholders prior to the combination, former GCI Liberty stockholders (in the aggregate) are expected to receive in the combination shares of Liberty Broadband Series C common stock, Liberty Broadband Series B common stock and Liberty Broadband Preferred Stock representing approximately 10.5%, 24.1% and 100.0%, respectively, of the total number of outstanding shares of Liberty Broadband Series C common stock, Liberty Broadband Series B common stock and Liberty Broadband Preferred Stock, respectively, based on approximately 170.9 million, 3.2 million and 7.2 million shares of Liberty Broadband Series C common stock, Liberty Broadband Series B common stock and Liberty Broadband Preferred Stock, respectively, currently expected to be outstanding at the effective time and after giving effect to the exchange agreement. As a result, former GCI Liberty stockholders (in the aggregate) are expected to own shares of Liberty Broadband Series B common stock and Liberty Broadband Preferred Stock representing approximately 16.7% of the aggregate voting power of outstanding shares of Liberty Broadband Series A common stock, par value $0.01 per share (“Liberty Broadband Series A common stock,” and together with Liberty Broadband Series B common stock, Liberty Broadband Series C common stock, “Liberty Broadband common stock,” and together with Liberty Broadband Preferred Stock, “Liberty Broadband capital stock”), Liberty Broadband Series B common stock and Liberty Broadband Preferred Stock, based on approximately 26.5 million, 3.2 million and 7.2 million shares of Liberty Broadband Series A common stock, Liberty Broadband Series B common stock and Liberty Broadband Preferred Stock, respectively, currently expected to be outstanding at the effective time and after giving effect to the exchange agreement.

Q:    What are Liberty Broadband stockholders being asked to vote on, and why is this approval necessary?

A:

Liberty Broadband stockholders are being asked to vote on the following proposals:

1.

Liberty Broadband Merger Proposal: A proposal to approve the adoption of the merger agreement, which is referred to as the “Liberty Broadband merger proposal” and is further described in the section titled “The Merger Agreement.” A copy of the merger agreement is attached as Annex A to this joint proxy statement/prospectus.

2.

Share Issuance Proposal: A proposal to approve the issuance of shares of Liberty Broadband Series C common stock, Liberty Broadband Series B common stock and Liberty Broadband Preferred Stock to GCI Liberty stockholders in connection with the combination contemplated by the merger agreement and shares of Liberty Broadband Series C common stock and Liberty Broadband Series B common stock to Mr. Malone or the JCM Trust pursuant to the exchange agreement (collectively, the “share issuance” and such proposal, the “share issuance proposal”).

The Liberty Broadband Series C common stock and Liberty Broadband Series A common stock are listed on (and the Liberty Broadband Preferred Stock to be issued will be listed on) the Nasdaq Global Select Market, and as a result, Liberty Broadband is subject to the Nasdaq Listing Rules, including with respect to stockholder approval requirements. Nasdaq Listing Rule 5635(a) states: “Shareholder approval is required prior to the issuance of securities in connection with the acquisition of the stock or assets of another company if: . . . (1) where, due to the present or potential issuance of common stock . . . other than a public offering for cash . . . the common stock has or will have upon issuance voting power equal to or in excess of 20% of the voting power outstanding before the issuance of stock or securities convertible into or exercisable for common stock; or (2) any director, officer or substantial shareholder . . . of the [c]ompany has a 5% or greater interest (or such persons collectively have a 10% or greater interest), directly or indirectly, in the [c]ompany . . . to be acquired or in the consideration to be paid in the transaction or series of related transactions and the present or potential issuance of common stock, or securities convertible into or exercisable for common stock, could result in an increase in outstanding common shares or voting power of 5% or more.” In connection with the combination, Liberty Broadband expects that the aggregate voting power of Liberty Broadband Series B common stock and Liberty Broadband Preferred Stock to be issued, or which may become issuable, in connection with the combination and the exchange agreement will exceed 20% of its outstanding voting power prior to such share issuance. In addition, Mr. Malone, Chairman of the Board of Liberty Broadband and GCI Liberty, Richard R. Green and J. David Wargo, who are members of the Liberty Broadband Board, and the Parent Section 16 Officers (as defined in the merger agreement) collectively have a greater than 10% interest in GCI Liberty, and the share issuance will result in an increase in outstanding common stock and voting power of 5% or more. Furthermore, Liberty Broadband is required by the terms of the merger agreement to submit the share issuance proposal to its stockholders at a special meeting.

3.

Liberty Broadband Adjournment Proposal: A proposal to approve the adjournment of the Liberty Broadband special meeting from time to time to solicit additional proxies in favor of the Liberty Broadband merger proposal or the share issuance proposal if there are insufficient votes at the time of such adjournment to approve the Liberty Broadband merger proposal or the share issuance proposal or if otherwise determined by the chairperson of the meeting to be necessary or appropriate (the “Liberty Broadband adjournment proposal”).

Completion of the combination is conditioned on Liberty Broadband stockholders approving the Liberty Broadband merger proposal and the share issuance proposal. The completion of the combination is not conditioned on the approval of the Liberty Broadband adjournment proposal.

Q:    What votes are required to approve the Liberty Broadband merger proposal, the share issuance proposal and the Liberty Broadband adjournment proposal?

A:

Approval of the Liberty Broadband merger proposal requires the affirmative vote of the holders of a majority of the aggregate voting power of the shares of Liberty Broadband common stock outstanding and entitled to vote on the proposal at the Liberty Broadband special meeting, voting together as a single class, excluding all outstanding shares beneficially owned, directly or indirectly, by GCI Liberty and its subsidiaries, Mr. Malone and certain affiliated persons of Mr. Malone (collectively, the “Malone Group”), Mr. Gregory B. Maffei, a director and the President and Chief Executive Officer of Liberty Broadband and GCI Liberty, and certain affiliated persons of Mr. Maffei (collectively, the “Maffei Group”) each of the Affiliates (as defined in the merger agreement) of the Malone Group or the Maffei Group, the directors of Liberty Broadband and GCI Liberty, the Parent Section 16 Officers, the Company Section 16 Officers (as defined in the merger agreement) or immediate family members of any of the foregoing. Approval of each of the share issuance proposal and the Liberty Broadband adjournment proposal requires the affirmative vote of the holders of a majority of the aggregate voting power of the shares of Liberty Broadband common stock that are present in person via the Internet or represented by proxy at the Liberty Broadband special meeting and entitled to vote on the proposal at the Liberty Broadband special meeting, voting together as a single class.

Q:    What are GCI Liberty stockholders being asked to vote on, and why is this approval necessary?

A:

GCI Liberty stockholders are being asked to vote on the following proposals:

1.

GCI Liberty Merger Proposal: A proposal to approve the adoption of the merger agreement, which is referred to as the “GCI Liberty merger proposal” and further described in the section titled “Special Factors—The Merger Agreement.” A copy of the merger agreement is attached as Annex A to this joint proxy statement/prospectus; and

2.

Completion of the combination is conditioned on GCI Liberty stockholders approving the GCI Liberty merger proposal. The completion of the combination is not conditioned on the approval of the GCI Liberty adjournment proposal.

Q:    What votes are required to approve the GCI Liberty merger proposal and the GCI Liberty adjournment proposal?

A:

Approval of the GCI Liberty merger proposal requires both (i) the affirmative vote of the holders of a majority of the aggregate voting power of the shares of GCI Liberty capital stock outstanding and entitled to vote on the proposal at the GCI Liberty special meeting, voting together as a single class, and (ii) the affirmative vote of the holders of a majority of the aggregate voting power of the shares of GCI Liberty capital stock outstanding and entitled to vote on the proposal at the GCI Liberty special meeting, voting together as a single class, excluding all outstanding shares beneficially owned, directly or indirectly, by Liberty Broadband and its subsidiaries, the Malone Group, the Maffei Group, each of the Affiliates of the Malone Group or the Maffei Group, the

Q:    How many votes do Liberty Broadband stockholders have with respect to the Liberty Broadband special meeting?

A:

Each stockholder of record of Liberty Broadband is entitled to one vote for each share of Liberty Broadband Series A common stock and ten votes for each share of Liberty Broadband Series B common stock, in each case, held on of 5:00 p.m., New York City time, on [    ·    ], 2020 (the “record date”). The holders of record of Liberty Broadband Series C common stock are not entitled to any voting powers, except as required by Delaware law, and may not vote on the proposals to be presented at the Liberty Broadband special meeting.

On the record date, there were [    ·    ] shares of Liberty Broadband Series A common stock outstanding and [    ·    ] shares of Liberty Broadband Series B common stock outstanding.

In connection with the transactions contemplated by the merger agreement, Mr. Malone and certain members of the Malone Group entered into a voting agreement with Liberty Broadband and GCI Liberty (the "Liberty Broadband voting agreement"). Pursuant to the Liberty Broadband voting agreement, Mr. Malone and certain members of the Malone Group have committed to vote all of their shares of Liberty Broadband common stock, representing approximately 48.3% of the aggregate voting power of the issued and outstanding shares of Liberty Broadband common stock as of August 31, 2020, in favor of the share issuance proposal and the Liberty Broadband adjournment proposal. The Liberty Broadband voting agreement is described in more detail in “Special Factors—Other Agreements Related to the Combination—Liberty Broadband Voting Agreement.”

Q:    How many votes do GCI Liberty stockholders have with respect to the GCI Liberty special meeting?

A:

Each stockholder of GCI Liberty is entitled to one vote for each share of GCI Liberty Series A common stock, ten votes for each share of GCI Liberty Series B common stock and one-third of a vote for each share of GCI Liberty Preferred Stock, in each case, held on the record date.

On the record date, there were [    ·    ] shares of GCI Liberty Series A common stock outstanding, [    ·    ] shares of GCI Liberty Series B common stock outstanding and [    ·    ] shares of GCI Liberty Preferred Stock outstanding.

In connection with the transactions contemplated by the merger agreement, Mr. Malone and certain members of the Malone Group entered into a voting agreement with GCI Liberty and Liberty Broadband (the “GCI Liberty voting agreement,” and, together with the Liberty Broadband voting agreement, the “voting agreements”). Pursuant to the GCI Liberty voting agreement, Mr. Malone and certain members of the Malone Group have committed to vote all of their shares of GCI Liberty capital stock, representing approximately 27.0% of the aggregate voting power of the issued and outstanding shares of GCI Liberty capital stock as of August 31, 2020, in favor of the GCI Liberty merger proposal and the GCI Liberty adjournment proposal. The GCI Liberty voting agreement is described in more detail in “Special Factors—Other Agreements Related to the Combination—GCI Liberty Voting Agreement.”

Q:    What constitutes a quorum for the Liberty Broadband special meeting and GCI Liberty special meeting?

A:

In order to conduct the business at either special meeting, a quorum must be present.

Liberty Broadband. The presence at the Liberty Broadband special meeting online, in person via the Internet or represented by proxy, of the holders of a majority in total voting power of the shares of Liberty Broadband common stock outstanding on the record date and entitled to vote at the Liberty Broadband special meeting will constitute a quorum for the transaction of business at the Liberty Broadband special meeting. Abstentions will count for the purpose of determining the presence of a quorum for the transaction of business at the Liberty Broadband special meeting.

GCI Liberty. Similarly, the presence at the GCI Liberty special meeting online, in person via the Internet or represented by proxy, of the holders of a majority in total voting power of the shares of GCI Liberty capital stock outstanding on the record date and entitled to vote at the GCI Liberty special meeting will constitute a quorum for the transaction of business at the GCI Liberty special meeting. Abstentions will count for the purpose of determining the presence of a quorum for the transaction of business at the GCI Liberty special meeting.

Because applicable rules of the New York Stock Exchange and the Nasdaq Stock Market LLC (“Nasdaq”) do not permit discretionary voting by brokers with respect to any of the proposals to be acted upon at either special meeting, if you hold your shares of Liberty Broadband common stock or GCI Liberty capital stock through banks or brokers, your shares will not count as present and entitled to vote for purposes of determining a quorum, unless you instruct your bank or broker on how to vote your shares. This may make it more difficult to establish a quorum at the Liberty Broadband special meeting and the GCI Liberty special meeting.

Q:    How do the boards of directors of Liberty Broadband and GCI Liberty recommend that stockholders vote?

A:

Liberty Broadband. The Liberty Broadband Board, after considering various factors and acting on the unanimous recommendation of the Liberty Broadband special committee (as defined below), has unanimously determined that the merger agreement and the other transaction documents, and the transactions contemplated thereby (including the transactions contemplated by the voting agreements and the exchange agreement), are advisable and fair to, and in the best interests of, Liberty Broadband and its stockholders (other than GCI Liberty, the Malone Group, the Maffei Group, each of their respective Affiliates and the Parent Section 16 Officers) and unanimously recommends that Liberty Broadband stockholders vote “FOR” the Liberty Broadband merger proposal, “FOR” the share issuance proposal and “FOR” the Liberty Broadband adjournment proposal. For the factors considered by the Liberty Broadband special committee in making its recommendation to the Liberty Broadband Board and by the Liberty Broadband Board in reaching its decision to approve the merger agreement and the other transaction documents and to recommend the share issuance proposal and Liberty Broadband merger proposal to the Liberty Broadband stockholders, see “Special Factors—Liberty Broadband, Merger Sub and Merger LLC's Purpose and Reasons for the Combination; Recommendations of the Liberty Broadband Special Committee and Liberty Broadband Board of Directors.”

Q:    Have any Liberty Broadband stockholders or GCI Liberty stockholders agreed to vote their shares in favor of any of the proposals?

A:

Liberty Broadband. Pursuant to the Liberty Broadband voting agreement, Mr. Malone and certain members of the Malone Group have committed to vote all of their shares of Liberty Broadband common stock, representing approximately 48.3% of the aggregate voting power of the issued and outstanding shares of Liberty Broadband common stock as of August 31, 2020, in favor of the share issuance proposal and the Liberty Broadband adjournment proposal.

GCI Liberty. Pursuant to the GCI Liberty voting agreement, Mr. Malone and certain members of the Malone Group have committed to vote all of their shares of GCI Liberty capital stock, representing approximately 27.0% of the aggregate voting power of the issued and outstanding shares of GCI Liberty capital stock as of August 31, 2020, in favor of the GCI Liberty merger proposal and the GCI Liberty adjournment proposal.

Q:    What were the roles of the Liberty Broadband special committee and the GCI Liberty special committee?

A:

Liberty Broadband. The Liberty Broadband Board established the Liberty Broadband special committee, consisting solely of independent and disinterested directors of Liberty Broadband (the “Liberty Broadband special committee”), to determine whether to pursue the combination or any alternative transaction and to review, negotiate and evaluate the terms of the combination on behalf of the unaffiliated stockholders of Liberty Broadband (which excludes the Malone Group, the Maffei Group, each of their respective Affiliates and the Parent Section 16 Officers), with the assistance of its legal and financial advisors. On August 5, 2020, after extensive consultation with, and acting with the advice of, its own independent legal and financial advisors, the Liberty Broadband special committee unanimously (i) determined that the merger agreement and the other transaction documents and the transactions contemplated thereby (including the transactions contemplated by the voting agreements and the exchange agreement), are advisable and fair to, and in the best interests of, Liberty Broadband and the Liberty Broadband stockholders (other than GCI Liberty, the Malone Group, the Maffei Group, each of their respective Affiliates and Parent Section 16 Officers), and (ii) recommended that the Liberty Broadband Board approve and declare advisable the merger agreement and the other transaction documents and the transactions contemplated thereby (including the transactions contemplated by the voting agreements and the

exchange agreement), and submit the share issuance proposal and Liberty Broadband merger proposal to the Liberty Broadband stockholders.

GCI Liberty. The GCI Liberty Board established the GCI Liberty special committee, consisting solely of independent and disinterested directors of GCI Liberty (the “GCI Liberty special committee”), to determine whether to pursue the combination or any alternative transaction and to negotiate, review and evaluate the terms and conditions of, and determine the advisability of, the combination on behalf of the unaffiliated stockholders of GCI Liberty (which excludes the Malone Group, the Maffei Group, each of their respective Affiliates and the Company Section 16 Officers), each with the assistance of its legal and financial advisors. On August 6, 2020, after extensive consultation with, and acting with the advice of, its own independent legal and financial advisors, the GCI Liberty special committee unanimously (i) determined that the merger agreement and the other transaction documents, and the transactions contemplated by the transaction documents (including the transactions contemplated by the voting agreements and the exchange agreement), are advisable and fair to, and in the best interests of, GCI Liberty and its stockholders (other than the Malone Group, the Maffei Group, each of their respective Affiliates and the Company Section 16 Officers) and (ii) recommended that the GCI Liberty Board approve and declare advisable the merger agreement and the other transaction documents, and the transactions contemplated by the transaction documents (including the transactions contemplated by the voting agreements and the exchange agreement), and submit the GCI Liberty merger proposal to the GCI Liberty stockholders.

Q:    Did a majority of independent directors of Liberty Broadband or a majority of independent directors of GCI Liberty retain an unaffiliated representative to act solely on behalf of unaffiliated security holders of Liberty Broadband or GCI Liberty, respectively, for purposes of negotiating the terms of the combination and/or preparing an opinion concerning the fairness of the combination?

A:

As described more fully in the section entitled “Special Factors—Background of the Combination,” prior to any negotiations, including any discussions regarding a possible exchange ratio or regarding any potential arrangements with Mr. Malone, the Liberty Broadband special committee and GCI Liberty special committee, each consisting solely of independent and disinterested directors, were established and agreed with each other and with Mr. Malone that any potential business combination transaction between Liberty Broadband and GCI Liberty would be subject to and conditioned upon, among other things, the negotiation by, and approval of, each special committee. In addition, the Liberty Broadband special committee retained Perella Weinberg Partners LP (“Perella Weinberg Partners”) as its financial advisor and for purposes of preparing an opinion as to the fairness of the Series A merger consideration and the Series B merger consideration in connection with the first merger, from a financial point of view, to all stockholders of Liberty Broadband other than GCI Liberty, the Malone Group, the Maffei Group, each of their respective Affiliates and the Parent Section 16 Officers. For a description of this report, see “Special Factors—Opinion of the Liberty Broadband Special Committee's Financial Advisor.” Also, the GCI Liberty special committee retained Evercore Group L.L.C. (“Evercore”) as its financial advisor and for purposes of preparing an opinion as to the fairness, from a financial point of view, of the exchange ratio in the first merger to the holders of GCI Liberty Series A common stock and GCI Liberty Series B common stock (together, “GCI Liberty common stock”), other than the Malone Group, the Maffei Group and their respective Affiliates and the Company Section 16 Officers. For a description of Evercore's opinion, see “Special Factors—Opinion of the GCI Liberty Special Committee's Financial Advisor.”

Q:    What does the opinion of Perella Weinberg Partners provide?

A:

The Liberty Broadband special committee requested that Perella Weinberg Partners evaluate the fairness of the Series A merger consideration and the Series B merger consideration (together, the “Common Consideration”) in connection with the first merger, from a financial point of view, to all stockholders of Liberty Broadband other than GCI Liberty, the Malone Group, the Maffei Group, each of their respective Affiliates and the Parent Section 16 Officers. Perella Weinberg Partners rendered its oral opinion to the Liberty Broadband special committee on August 5, 2020, which was subsequently confirmed in writing, that, as of August 5, 2020 and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth therein, the Common Consideration to be paid in connection with the first merger pursuant to the merger agreement was fair, from a financial point of view, to the stockholders of Liberty Broadband other than GCI Liberty, the Malone Group, the Maffei Group, each of their respective Affiliates and Parent Section 16 Officers.

The full text of Perella Weinberg Partners' written opinion, dated August 5, 2020, which sets forth, among other things, the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by Perella Weinberg Partners, is attached to this joint proxy statement/prospectus as Annex B and is incorporated by reference herein.

Perella Weinberg Partners provided its opinion for the information and assistance of the Liberty Broadband special committee and the Liberty Broadband Board in connection with, and for the purposes of their evaluation of, the first merger. The opinion was not intended to be and does not constitute a recommendation to the Liberty Broadband special committee or the Liberty Broadband Board or to any other persons in respect of the first merger, including as to whether or how any holder of the Liberty Broadband Series A common stock or Liberty Broadband Series B common stock should vote or otherwise act with respect to the first merger or any other matter. In addition, Perella Weinberg Partners expressed no opinion as to the fairness of the first merger to, or any consideration received in connection with the first merger by, holders of any class of securities, creditors or other constituencies of Liberty Broadband other than GCI Liberty, the Malone Group, the Maffei Group, each of their respective Affiliates and the Parent Section 16 Officers. In addition, Perella Weinberg Partners' opinion was rendered as of August 5, 2020 and did not consider, and does not give effect to, the sale of Evite on September 14, 2020. The summary of the opinion of Perella Weinberg Partners in the section entitled “Special Factors—Opinion of the Liberty Broadband Special Committee's Financial Advisor” is qualified in its entirety by reference to the full text of the opinion.

Q:    What does the opinion of Evercore provide?

A:

On August 6, 2020, at a meeting of the GCI Liberty special committee, Evercore rendered to the GCI Liberty special committee its oral opinion, subsequently confirmed by delivery of its written opinion, that, as of August 6, 2020, and based upon and subject to the assumptions, qualifications, limitations and other matters described in its written opinion, the exchange ratio in the first merger was fair, from a financial point of view, to the holders of GCI Liberty common stock, other than the Malone Group, the Maffei Group and their respective Affiliates and the Company Section 16 Officers. At the request of the GCI Liberty special committee, subsequently on August 6, 2020, Evercore also rendered its opinion to the GCI Liberty Board.

The full text of Evercore's written opinion, dated August 6, 2020, which sets forth, among other things, the assumptions made, procedures followed, matters considered and qualifications and limitations on the scope of review undertaken by Evercore in rendering its opinion, is attached as Annex C to this joint proxy statement/prospectus and is incorporated herein by reference in its entirety. The description of Evercore's opinion set forth in this joint proxy statement/prospectus is

qualified in its entirety by the full text of such opinion. GCI Liberty stockholders are encouraged to read Evercore's opinion carefully and in its entirety. Evercore's opinion was addressed to, and provided for the information and benefit of, the GCI Liberty special committee, and, at the GCI Liberty special committee's request, the GCI Liberty Board in connection with their respective evaluations of the combination. The opinion does not constitute a recommendation to the GCI Liberty special committee, the GCI Liberty Board or to any other person in respect of the combination, including as to how any holder of shares of GCI Liberty common stock should vote or act in respect of the combination. Evercore's opinion does not address the relative merits of the combination as compared to other business or financial strategies that might be available to GCI Liberty, nor does it address the underlying business decision of GCI Liberty to engage in the combination. In addition, Evercore's opinion was rendered as of August 6, 2020 and did not consider, and does not give effect to, the sale of Evite on September 14, 2020.

Q:    Did the parties agree to any conditions in connection with the negotiation of the combination?

A:

Prior to any negotiations, including any discussion regarding the exchange ratio, the Liberty Broadband special committee and GCI Liberty special committee agreed with each other and with Mr. Malone that any potential business combination transaction between Liberty Broadband and GCI Liberty would be subject to and conditioned upon the negotiation by, and approval of, each special committee and a non-waivable condition requiring the approval of the holders of a majority of the voting power of the outstanding shares of each company not owned by Mr. Malone or any other interested parties.

Q:    What is the accounting treatment for the combination?

A:

Liberty Broadband and GCI Liberty prepare their financial statements, respectively, in accordance with accounting principles generally accepted in the United States (“GAAP”). Liberty Broadband will account for the acquisition of GCI Liberty as a business combination and the repurchase of Liberty Broadband shares held by GCI Liberty as a transaction separate from the business combination. Therefore, Liberty Broadband will account for the acquired GCI Liberty assets and liabilities as a business combination at their respective acquisition date fair values, and the acquisition of Liberty Broadband shares held by GCI Liberty as a share repurchase. For more information, see “Special Factors—Accounting Treatment.”

Q:    What regulatory approvals are required to complete the combination?

A:

Liberty Broadband and GCI Liberty submitted applications to the United States Federal Communications Commission (the “FCC”) for authorization to transfer control from GCI Liberty to Liberty Broadband of certain FCC licenses, authorizations, approvals and registrations currently held indirectly by GCI Liberty. The FCC must approve such transfer of control, and the FCC approval(s) must become a final order before the combination may take place.

Liberty Broadband and GCI Liberty submitted applications to the Regulatory Commission of Alaska (the “RCA”) for approval for Liberty Broadband to acquire a controlling interest in certificates of public convenience and necessity held by certain subsidiaries of GCI Liberty. The RCA's approval must become a final order before the combination may take place.

The combination is subject to the requirements of the Hart-Scott-Rodino Act (the “HSR Act”), which provides that certain transactions may not be completed until required information and materials are furnished to the Antitrust Division of the Department of Justice (the “DOJ”), and the Federal Trade Commission (the “FTC”), and until certain waiting period requirements have been satisfied. Each of Liberty Broadband and GCI Liberty submitted a Notification and Report Form under the HSR Act with the DOJ and the FTC in connection with the combination on September 9, 2020. The waiting period is scheduled to expire at 11:59 p.m., Eastern Time, on October 9, 2020.

The DOJ, the FTC, state attorneys general, and others may challenge the combination on antitrust grounds after the expiration or termination of the applicable waiting period. Accordingly, at any time before or after the completion of the combination, any of the DOJ, the FTC or others could take action under the antitrust laws, including without limitation seeking to enjoin the completion of the combination or permitting completion subject to regulatory concessions or conditions. Neither Liberty Broadband nor GCI Liberty believes that the combination violates U.S. antitrust laws, but there can be no assurance that a challenge to the combination on antitrust grounds will not be made or, if such a challenge is made, that it would not be successful.

Q:    What do I need to do now?

A:

After carefully reading and considering the information contained in this joint proxy statement/prospectus, please vote your shares of Liberty Broadband common stock and/or GCI Liberty capital stock as soon as possible so that your shares will be represented at the applicable special meeting. Please follow the instructions set forth on the proxy card or on the voting instruction form provided by your broker, bank or other nominee.

Please do not submit your stock certificates at this time. If the combination is completed, GCI Liberty stockholders will receive instructions for surrendering their stock certificates in exchange for shares of Liberty Broadband Series B common stock, Liberty Broadband Series C common stock and/or Liberty Broadband Preferred Stock from the exchange agent.

Q:    Does my vote matter?

A:

Liberty Broadband Stockholders. Yes. Completion of the combination is conditioned on Liberty Broadband stockholders approving the Liberty Broadband merger proposal and the share issuance proposal. An abstention with respect to either of these proposals will have the same effect as a vote “AGAINST” such proposal. If you fail to submit a proxy or to vote via the Internet during the Liberty Broadband special meeting or you do not provide your broker, bank or other nominee with voting instructions, as applicable, this will have the effect of a vote “AGAINST” the Liberty Broadband merger proposal and it will have no effect on the outcome of the share issuance proposal (assuming a quorum is present). The Liberty Broadband Board unanimously recommends that Liberty Broadband stockholders vote “FOR” the Liberty Broadband merger proposal and “FOR” the share issuance proposal.

The completion of the combination is not conditioned on the approval of the Liberty Broadband adjournment proposal. An abstention will have the same effect as a vote “AGAINST” the Liberty Broadband adjournment proposal. If you fail to submit a proxy or to vote via the Internet during the Liberty Broadband special meeting or you do not provide your broker, bank or other nominee with voting instructions, as applicable, it will have no effect on the outcome of the Liberty Broadband adjournment proposal (assuming a quorum is present). The Liberty Broadband Board unanimously recommends that Liberty Broadband stockholders vote “FOR” the Liberty Broadband adjournment proposal.

GCI Liberty Stockholders.    Yes. Completion of the combination is conditioned on GCI Liberty stockholders approving the GCI Liberty merger proposal. An abstention with respect to this proposal will have the same effect as a vote “AGAINST” such proposal. If you fail to submit a proxy or to vote via the Internet during the GCI Liberty special meeting or you do not provide your broker, bank or other nominee with voting instructions, as applicable, this will have the effect of a vote “AGAINST” the GCI Liberty merger proposal. The GCI Liberty Board unanimously recommends that GCI Liberty stockholders vote “FOR” the GCI Liberty merger proposal.

The completion of the combination is not conditioned on the approval of the GCI Liberty adjournment proposal. An abstention will have the same effect as a vote “AGAINST” the GCI

Liberty adjournment proposal. If you fail to submit a proxy or to vote via the Internet during the GCI Liberty special meeting or you do not provide your broker, bank or other nominee with voting instructions, as applicable, it will have no effect on the outcome of the GCI Liberty adjournment proposal (assuming a quorum is present). The GCI Liberty Board unanimously recommends that GCI Liberty stockholders vote “FOR” the GCI Liberty adjournment proposal.

Q:    How do I vote?

A:

If you are a stockholder of record of Liberty Broadband and/or GCI Liberty on the record date, you are entitled to receive notice of, and vote at, the Liberty Broadband special meeting and/or GCI Liberty special meeting, as applicable. You may submit your proxy before the special meeting in one of the following ways:

•

Via the Internet—visit the website shown on your proxy card to vote via the Internet;

•

Telephone voting—use the toll-free number shown on your proxy card; or

•

Mail—complete, sign, date and return the enclosed proxy card in the enclosed postage-paid envelope.

If you send the proxy by mail, there may be unexpected delays in mail processing times as a result of the COVID-19 pandemic. You should allow a sufficient number of days to ensure delivery.

If you are a stockholder of record, you may also vote via the Internet during the applicable special meeting. Liberty Broadband stockholders of record may vote their shares via the Internet during the Liberty Broadband special meeting by visiting www.virtualshareholdermeeting.com/[    ·    ]. GCI Liberty stockholders of record may vote their shares via the Internet during the GCI Liberty special meeting by visiting www.virtualshareholdermeeting.com/[    ·    ]. To enter the Liberty Broadband special meeting and the GCI Liberty special meeting, Liberty Broadband stockholders and GCI Liberty stockholders, respectively, will need the 16-digit control number that is printed in the box marked by the arrow on their proxy cards. Each company recommends that its respective stockholders log in at least fifteen minutes before the applicable special meeting to ensure that they are logged in when the meeting starts. Online check-in will start shortly before the meeting on [    ·    ], 202[    ·    ].

If your shares are held in “street name,” through a broker, bank or other nominee, that institution will send you separate instructions describing the procedure for voting your shares. “Street name” stockholders who wish to vote at the meeting will need to obtain a “legal proxy” form from their broker, bank or other nominee.

Q:    What is the difference between holding shares as a stockholder of record and holding shares in “street name” as a beneficial owner?

A:

You are a “stockholder of record” if your shares are registered directly in your name with Broadridge Corporate Issuer Solutions, Inc., the transfer agent for Liberty Broadband and GCI Liberty. As the stockholder of record, you have the right to vote via the Internet during the applicable special meeting. You may also vote by Internet, telephone or mail, as described in the notice and above under the heading “How do I vote?” You are deemed to beneficially own shares in “street name” if your shares are held by a broker, bank or other nominee or other similar organization. Your broker, bank or other nominee will send you, as the beneficial owner, a package describing the procedure for voting your shares. You should follow the instructions provided by them to vote your shares. If you beneficially own your shares, you are invited to attend the special meeting; however, you may not vote your shares in person via the Internet at the special meeting unless you obtain a “legal proxy” from your broker, bank or other nominee that holds your shares, giving you the right to vote the shares at the special meeting.

Q:    If I am a record holder, what will happen if I return my signed proxy without indicating how to vote?

A:

If you are a record holder and sign and return your proxy without indicating how to vote on any particular proposal, stock represented by your proxy will be voted as recommended by the Liberty Broadband Board or GCI Liberty Board, as applicable.

Q:    May I change or revoke my vote after I have delivered my proxy or voting instruction form?

A:

Yes. Any stockholder giving a proxy has the power to revoke it at any time before the proxy is voted at the applicable special meeting. If you are a stockholder of record, you may revoke your proxy in any of the following ways:

•

by logging onto the Internet website specified on your proxy card in the same manner you would to submit your proxy electronically or by calling the telephone number specified on your proxy card, in each case, if you are eligible to do so;

•

by sending a notice of revocation or a completed proxy card bearing a later date than your original proxy card to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717; or

•

by attending and voting at the applicable special meeting.

Any signed proxy revocation or new signed proxy must be received before the beginning of the applicable special meeting. In addition, you may change your vote through the Internet or by telephone (if you originally voted by the corresponding method) not later than [11:59 p.m., New York City time], on [    ·    ], 202[    ·    ].

If your shares are held by a broker, bank or other nominee, you may change your vote by submitting new voting instructions to your broker, bank or other nominee. You must contact your broker, bank or other nominee to find out how to do so.

Q:    If my shares are held in “street name” by a broker, bank or other nominee, will my broker, bank or other nominee vote my shares for me?

A:

If your shares are held in “street name” in a stock brokerage account or by a broker, bank or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your broker, bank or other nominee. Please note that you may not vote shares held in street name by returning a proxy card directly to Liberty Broadband or GCI Liberty, as applicable, or by voting in person via the Internet at the applicable special meeting unless you provide a “legal proxy,” which you must obtain from your broker, bank or other nominee. Your broker, bank or other nominee is obligated to provide you with a voting instruction form for you to use.

Brokers who hold shares in street name for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are not allowed to exercise their voting discretion with respect to the approval of matters determined to be “non-routine” without specific instructions from the beneficial owner. It is expected that all of the proposals to be voted on at each of the special meetings are “non-routine” matters.

If you are a beneficial owner of shares and you do not instruct your broker, bank or other nominee on how to vote your shares:

•

your shares will not be counted as present and entitled to vote for purposes of determining a quorum;

•

Liberty Broadband stockholders—your broker, bank or other nominee may not vote your shares, which will have the effect of a vote “AGAINST” the Liberty Broadband merger proposal and will have no effect on the outcome of the share issuance proposal (assuming a quorum is present) and the Liberty Broadband adjournment proposal (assuming a quorum is present).



•

GCI Liberty stockholders—your broker, bank or other nominee may not vote your shares, which will have the effect of a vote “AGAINST” the GCI Liberty merger proposal and will have no effect on the outcome of the GCI Liberty adjournment proposal (assuming a quorum is present).

Q:    Do GCI Liberty stockholders need to do anything with their stock certificates now?

A:

No. You should not submit your GCI Liberty stock certificates at this time. Promptly after the effective time, if you held certificates representing GCI Liberty capital stock immediately prior to the effective time, Broadridge Corporate Issuer Solutions, Inc., the exchange agent for Liberty Broadband, will send you a letter of transmittal and instructions for exchanging your shares of GCI Liberty capital stock for the merger consideration. Upon surrender of the certificates for cancellation along with the executed letter of transmittal and other required documents described in the instructions, a holder of shares of GCI Liberty capital stock will receive the merger consideration.

Holders of shares of GCI Liberty capital stock in book-entry form immediately prior to the effective time will not need to take any action to receive the merger consideration.

Q:    What are the U.S. federal income tax consequences of the combination?

A:

GCI Liberty and Liberty Broadband intend that the combination will qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). It is a condition to each of GCI Liberty's and Liberty Broadband's obligation to complete the combination that it receive a written opinion from Skadden, Arps, Slate, Meagher & Flom, LLP (“Skadden”), which is GCI Liberty's special tax counsel, and Debevoise & Plimpton, LLP (“Debevoise”), which is counsel to the Liberty Broadband special committee, respectively, to the effect that the combination will qualify as a “reorganization” within the meaning of Section 368(a) of the Code (each a “reorganization tax opinion”). Assuming the receipt and accuracy of the opinions described above, a U.S. holder (as defined under “Material U.S. Federal Income Tax Consequences of the Combination”) of GCI Liberty capital stock will not recognize gain or loss for U.S. federal income tax purposes as a result of the combination, except with respect to any cash received in lieu of fractional shares of Liberty Broadband Series C common stock or Liberty Broadband Series B common stock.

Please carefully review the information set forth in the section entitled “Material U.S. Federal Income Tax Consequences of the Combination” for a discussion of the U.S. federal income tax consequences of the combination. Please consult your own tax advisors as to the specific tax consequences to you of the combination.

Q:    Are Liberty Broadband stockholders or GCI Liberty stockholders entitled to appraisal rights in connection with the combination?

A:

Liberty Broadband stockholders—Under Delaware law, Liberty Broadband stockholders are not entitled to dissenters' or appraisal rights in connection with the combination or issuance of the merger consideration as contemplated by the merger agreement. Liberty Broadband stockholders may vote against the Liberty Broadband merger proposal and the share issuance proposal if they do not favor such proposals.

GCI Liberty stockholders—Under Delaware law, holders of shares of GCI Liberty Series A common stock and GCI Liberty Preferred Stock are not entitled to dissenters' or appraisal rights in connection with the combination as contemplated by the merger agreement.

Holders of shares of GCI Liberty Series B common stock are entitled to seek appraisal of their shares of GCI Liberty Series B common stock under the General Corporation Law of the State of Delaware (“DGCL”) in connection with the combination if any such holder (i) does not vote in favor of the GCI Liberty merger proposal and (ii) otherwise complies with the other conditions established by Section 262 of the DGCL. Failure to follow precisely any of the statutory requirements could result in the loss of appraisal rights. A detailed description of the appraisal rights and procedures available is included in “Special Factors—Appraisal Rights.” For the full text of Section 262 of the DGCL, please see Annex M hereto.

Q:    What will happen to GCI Liberty's outstanding equity awards?

•

all outstanding stock options to purchase shares of GCI Liberty Series A common stock and GCI Liberty Series B common stock will be converted into options, with the same terms and conditions (including, except in the case of any non-employee director of GCI Liberty, vesting terms) as applied to such GCI Liberty stock options immediately prior to the effective time, to purchase the number of shares of Liberty Broadband Series C common stock and Liberty Broadband Series B common stock (rounded down to the nearest whole share), respectively, determined by multiplying the number of shares of GCI Liberty common stock subject to the GCI Liberty stock option by 0.580, at an exercise price determined by dividing the per-share exercise price of the GCI Liberty stock option by 0.580 and rounding the result up to the nearest whole cent;

•

all outstanding stock options to purchase shares of GCI Liberty Series A common stock and GCI Liberty Series B common stock held by any non-employee director of GCI Liberty will automatically accelerate and vest in full immediately prior to the effective time;

•

all outstanding awards of restricted stock units and performance-based restricted stock units in respect of shares of GCI Liberty Series A common stock (other than those held by non-employee directors of GCI Liberty) will be converted into restricted stock unit awards or performance-based restricted stock unit awards, as applicable, with the same terms and conditions (including service-based or performance-based vesting requirements) as were applicable to each such award immediately prior to the effective time, relating to the number of shares of Liberty Broadband Series C common stock determined by multiplying the number of shares of GCI Liberty Series A common stock subject to the GCI Liberty restricted stock unit or performance-based restricted stock unit, as applicable, by 0.580, rounded down to the nearest whole share;

Q:    Do any of the directors or executive officers of Liberty Broadband have interests in the combination that may be different from, or in addition to, the interests of Liberty Broadband stockholders?

A:

When considering the recommendation of the Liberty Broadband Board with respect to the Liberty Broadband merger proposal and the share issuance proposal, Liberty Broadband stockholders should be aware that certain of Liberty Broadband's directors and executive officers may be deemed to have interests in the combination and the transactions contemplated thereby that are different from, or in addition to, those of Liberty Broadband stockholders. These interests may present such persons with actual or potential conflicts of interest. The Liberty Broadband

Board and the Liberty Broadband special committee were aware of these interests during the deliberations of the merits of the combination, and the transactions contemplated thereby, and in deciding to recommend that you vote for each of the Liberty Broadband merger proposal, the share issuance proposal and the Liberty Broadband adjournment proposal.

All of the Liberty Broadband executive officers are also executive officers of GCI Liberty and will continue to provide services in such capacity following the combination. The Liberty Broadband executive officers hold GCI Liberty equity awards, which were granted in respect of their service as GCI Liberty executive officers. Those awards will remain outstanding, subject to the same terms, conditions and vesting requirements, and be converted into equity awards with respect to Liberty Broadband stock, as described in more detail above under “Questions & Answers—What will happen to GCI Liberty's outstanding equity awards?”.

With respect to the Liberty Broadband directors and executive officers, areas where their interests may differ from those of Liberty Broadband stockholders in general relate to the indemnification and insurance protections for their service as directors and executive officers pursuant to the Liberty Broadband organizational documents.

With respect to the Liberty Broadband directors serving on the Liberty Broadband special committee, areas where their interests may differ from those of Liberty Broadband stockholders in general relate to cash compensation for services on the Liberty Broadband special committee.

With respect to Mr. Malone, his interests may differ from those of Liberty Broadband stockholders in part due to the transactions contemplated by the exchange agreement. Pursuant to the exchange agreement, the JCM Trust waived its right to receive certain shares of Liberty Broadband Series B common stock in the combination (which number of such shares is subject to adjustment for subsequent exchanges between Mr. Malone and the JCM Trust on the one hand and Liberty Broadband on the other hand as further described below, the “waived B shares”) in respect of certain shares of GCI Liberty Series B common stock and, instead, agreed to receive an equal number of shares of Liberty Broadband Series C common stock so that Mr. Malone's voting power at Liberty Broadband (including shares held in certain trusts not party to the voting agreements) immediately following the effective time remains at approximately, but would not exceed, 49%. Following the effective time, there may be additional exchanges of Liberty Broadband Series B common stock and Liberty Broadband Series C common stock by Mr. Malone or the JCM Trust pursuant to the exchange agreement. For more information, please see “Special Factors—Other Agreements Related to the Combination—Exchange Agreement.”

Additionally, the Liberty Broadband Board and the GCI Liberty Board include three overlapping members: Mr. Malone, Mr. Maffei and Richard R. Green. Mr. Malone is a non-employee director and Chairman of the Board of Liberty Broadband, as well as Chairman of the Board of GCI Liberty. Mr. Maffei is President and Chief Executive Officer and a director of Liberty Broadband and GCI Liberty. Dr. Green is a non-employee director of Liberty Broadband and GCI Liberty.

For a detailed discussion of these and other interests, see “Special Factors—Interests of Liberty Broadband Directors and Executive Officers in the Combination.”

Q:    Do any of the directors or executive officers of GCI Liberty have interests in the combination that may be different from, or in addition to, the interests of GCI Liberty stockholders?

A:

When considering the recommendation of the GCI Liberty Board with respect to the GCI Liberty merger proposal, GCI Liberty stockholders should be aware that certain of GCI Liberty's directors and executive officers may be deemed to have interests in the combination and the transactions contemplated thereby that are different from, or in addition to, those of GCI Liberty stockholders. These interests may present such persons with actual or potential conflicts of interest. Excepting

only the Liberty Broadband Board's intention to appoint Gregg L. Engles and Sue Ann Hamilton as board members following the completion of the combination (as discussed below), which was not discussed with Mr. Engles or Ms. Hamilton nor were Mr. Engles or Ms. Hamilton aware of such intention prior to the execution of the merger agreement, the GCI Liberty Board and the GCI Liberty special committee were aware of these interests during the deliberations of the merits of the combination, and the transactions contemplated thereby, and in deciding to recommend that you vote for each of the GCI Liberty merger proposal and the GCI Liberty adjournment proposal.

With respect to the GCI Liberty directors and executive officers, areas where their interests may differ from those of GCI Liberty stockholders in general relate the indemnification and insurance protections for their service as directors and executive officers pursuant to the GCI Liberty organizational documents, which protections will be preserved following the combination. Additionally, any unvested GCI Liberty equity awards held by the GCI Liberty non-employee directors will vest immediately prior to the effective time.

With respect to the GCI Liberty directors serving on the GCI Liberty special committee, areas where their interests may differ from those of GCI Liberty stockholders in general relate to cash compensation for services on the GCI Liberty special committee.

With respect to Mr. Malone, his interests may differ from those of GCI Liberty stockholders in part due to the transactions contemplated by the exchange agreement. Pursuant to the exchange agreement, the JCM Trust waived its right to receive the waived B shares and, instead, agreed to receive an equal number of shares of Liberty Broadband Series C common stock so that the aggregate voting power of all of Liberty Broadband's securities over which Mr. Malone has beneficial ownership (including shares held in certain trusts not party to the voting agreements) immediately following the effective time will be approximately (but not more than) 49%. Following the effective time, there may be additional exchanges of Liberty Broadband Series B common stock and Liberty Broadband Series C common stock by Mr. Malone or the JCM Trust pursuant to the exchange agreement. For more information, please see “Special Factors—Other Agreements Related to the Combination—Exchange Agreement.”

Additionally, the Liberty Broadband Board and the GCI Liberty Board include three overlapping members: Mr. Malone, Mr. Maffei and Richard R. Green. Mr. Malone is a non-employee director and Chairman of the Board of Liberty Broadband, as well as Chairman of the Board of GCI Liberty. Mr. Maffei is President and Chief Executive Officer and a director of Liberty Broadband and GCI Liberty. Dr. Green is a non-employee director of Liberty Broadband and GCI Liberty.

The Liberty Broadband Board intends to, effective following the completion of the combination, increase its size from six directors to eight directors and appoint Gregg L. Engles and Sue Ann Hamilton, who are currently members of the GCI Liberty Board, to fill the vacancies created by such newly created directorships. Neither Mr. Engles nor Ms. Hamilton were aware of this intention, and no discussions occurred with Mr. Engles or Ms. Hamilton regarding their service on the Liberty Broadband Board following the completion of the combination prior to execution of the merger agreement.

For a detailed discussion of these and other interests, see “Special Factors—Interests of GCI Liberty Directors and Executive Officers in the Combination.”

Q:    What happens if I sell my shares of Liberty Broadband Series A common stock, Liberty Broadband Series B common stock or GCI Liberty capital stock after the record date but before the effective time?

A:

The record date for the Liberty Broadband special meeting (5:00 p.m., New York City time, on [    ·    ], 2020) is earlier than the date of the Liberty Broadband special meeting and earlier than

the date that the combination is expected to be completed. If you sell or otherwise transfer your shares of Liberty Broadband Series A common stock or Liberty Broadband Series B common stock after the record date but before the date of the special meeting, you will retain your right to vote at the Liberty Broadband special meeting, unless you have made arrangements to the contrary.

The record date for the GCI Liberty special meeting (5:00 p.m., New York City time, on [    ·    ], 2020) is earlier than the date of the GCI Liberty special meeting and earlier than the date that the combination is expected to be completed. If you sell or otherwise transfer your shares of GCI Liberty capital stock after the record date but before the date of the special meeting, you will retain your right to vote at the GCI Liberty special meeting, unless you have made arrangements to the contrary. However, you will not have the right to receive the merger consideration to be received by the GCI Liberty stockholders in the combination. In order to receive the merger consideration, you must hold your shares through the effective time. In addition, if you sell or otherwise transfer your shares of GCI Liberty Series B common stock prior to the effective time, you will lose any appraisal rights with respect to such shares.

Q:    Will the rights of GCI Liberty stockholders change as a result of the combination?

A:

GCI Liberty stockholders will have different rights once they become stockholders of Liberty Broadband due to differences between the governing documents of Liberty Broadband and GCI Liberty. These differences are described in detail under “Comparison of Rights of Liberty Broadband Stockholders and GCI Liberty Stockholders.” Holders of GCI Liberty Series A common stock will receive shares of non-voting Liberty Broadband Series C common stock in connection with the combination. Holders of GCI Liberty Preferred Stock will receive shares of Liberty Broadband Preferred Stock in connection with the combination, which will have substantially identical rights as compared to the GCI Liberty Preferred Stock.

Q:    What is the expected timing of the combination?

A:

Liberty Broadband and GCI Liberty are working to complete the combination in the first half of 2021. However, the combination is subject to various conditions, and it is possible that factors outside the control of Liberty Broadband and GCI Liberty could result in the combination being completed at a later time, or not at all. There may be a substantial amount of time between the respective Liberty Broadband special meeting and GCI Liberty special meeting and the completion of the combination. For more information, see “Risk Factors—Risks Related to the Combination.”

Q:    Is the completion of the combination subject to any conditions?

A:

As more fully described in “Special Factors—The Merger Agreement—Conditions to the Combination”, the completion of the first merger and the combination depends on a number of conditions being satisfied or (to the extent permitted) waived.

In addition to the approval of the GCI Liberty merger proposal, the Liberty Broadband merger proposal and the share issuance proposal, each of which cannot be waived, and any required approvals under the HSR Act, the obligations of GCI Liberty and Liberty Broadband to complete the first merger and the combination are subject to the satisfaction or waiver of certain other conditions, including:

•

the FCC having approved the application(s) for transfer of control and/or assignment of certain FCC licenses, authorizations, approvals and registrations and such FCC approvals having become a final order;

•

the RCA having issued a final order approving Liberty Broadband's application to acquire a controlling interest in certificates of public convenience and necessity held by certain subsidiaries of GCI Liberty;



•

the absence of any order or law that has the effect of enjoining or otherwise prohibiting the consummation of the combination or the transactions contemplated by the transaction documents;



•

the effectiveness of the registration statement on Form S-4 of which this joint proxy statement/prospectus forms a part;



•

the approval for listing on Nasdaq of the shares of Liberty Broadband Series C common stock and Liberty Broadband Preferred Stock to be issued in connection with the combination, subject to official notice of issuance;



•

the delivery of an opinion by Skadden to GCI Liberty to the effect that the transactions contemplated by the merger agreement will not impact the U.S. federal income tax treatment of the GCI Liberty Split-off (as defined below).


The respective obligation of each party to close also is conditioned on the satisfaction or waiver of the following conditions (among other things): (1) the receipt of an opinion from Skadden, GCI Liberty's special tax counsel, and the receipt of an opinion from Debevoise, counsel to the Liberty Broadband special committee, that, in each case, based on certain representations and assumptions, and subject to certain limitations and qualifications, the combination will qualify as a “reorganization,” as described in more detail in “Material U.S. Federal Income Tax Consequences of the Combination” and (2) the other party's representations and warranties being true and correct as of the date of the merger agreement (subject to customary exceptions), and the other party having performed in all material respects its obligations under the merger agreement.

We cannot be certain when, or if, the conditions to the combination will be satisfied or waived, or that the combination will be completed.

Q:    Can the parties solicit alternative transactions or can the Liberty Broadband Board or GCI Liberty Board change its recommendation?

A:

As more fully described in this joint proxy statement/prospectus and in the merger agreement, each of GCI Liberty and Liberty Broadband has agreed to non-solicitation obligations with respect to third-party acquisition proposals (including provisions restricting their ability to provide confidential information to third parties) and has agreed to certain restrictions on its and its representatives' ability to respond to any such proposals.

The GCI Liberty Board has agreed to recommend that GCI Liberty stockholders vote in favor of the adoption of the merger agreement, subject to its right to change its recommendation in response to a company superior proposal or company intervening event, each as described below in this joint proxy statement/prospectus, in each case if the GCI Liberty special committee or GCI Liberty Board (acting at the direction of the GCI Liberty special committee) determines in good faith after consultation with its outside counsel and financial advisor that failure to change its recommendation would be inconsistent with its fiduciary duties under applicable law. Notwithstanding any change in GCI Liberty's recommendation, the merger agreement is required to be submitted to the GCI Liberty stockholders at the GCI Liberty special meeting for the purposes of adopting the merger agreement unless the merger agreement is terminated by Liberty Broadband prior to such time.

The Liberty Broadband Board has agreed to recommend that Liberty Broadband stockholders vote in favor of the approval of the share issuance proposal and the adoption of the merger agreement, subject to its right to change its recommendation in response to a parent superior proposal or parent intervening event, each as described below in this joint proxy statement/prospectus, in each case if the Liberty Broadband special committee or Liberty Broadband Board (acting at the direction of the Liberty Broadband special committee) determines in good faith after consultation with its outside counsel and financial advisor that failure to change its recommendation would be inconsistent with its fiduciary duties under applicable law. Notwithstanding any change in Liberty Broadband's recommendation, the merger agreement is required to be submitted to the Liberty Broadband stockholders at the Liberty Broadband special meeting for the purposes of approving the share issuance proposal and adopting the merger agreement unless the merger agreement is terminated by GCI Liberty prior to such time.

For a more complete description of the limitations on solicitation of acquisition proposals from third parties and the ability of any of the GCI Liberty special committee, GCI Liberty Board, Liberty Broadband special committee or Liberty Broadband Board to change its recommendation in favor of the GCI Liberty merger proposal or Liberty Broadband merger proposal, see “Special Factors—The Merger Agreement—Covenants and Agreements—GCI Liberty No Solicitation,” “Special Factors—The Merger Agreement—Covenants and Agreements—Company Adverse Recommendation Change; Certain Prohibited Actions,” “Special Factors—The Merger Agreement—Covenants and Agreements—Liberty Broadband No Solicitation,” and “Special Factors—The Merger Agreement—Covenants and Agreements—Liberty Broadband Adverse Recommendation Change; Certain Prohibited Actions.”

Q:    Can the merger agreement be terminated by the parties?

The Exchange Agreement

        On August 6, 2020, Liberty Broadband, Mr. Malone and the JCM Trust entered into the exchange agreement.

        Pursuant to the exchange agreement, the JCM Trust waived its right to receive the waived B shares and, instead, agreed to receive an equal number of shares of Liberty Broadband Series C common stock so that, immediately following the effective time, Mr. Malone's voting power at Liberty Broadband (including shares held in certain trusts not party to the voting agreements) will be approximately (but not more than) 49%.

        Following the effective time, Mr. Malone and the JCM Trust may exchange a number of shares of Liberty Broadband Series C common stock on a one-for-one basis for the waived B shares in order to preserve Mr. Malone's target voting power following the occurrence of certain voting dilution events which would result in Mr. Malone's voting power falling below the target voting power less 0.5% and in certain other circumstances. Any shares of Liberty Broadband Series B common stock so received will decrease the number of waived B shares for purposes of the exchange agreement. Conversely, following any repurchase, redemption or certain other events that would result in Mr. Malone's voting power exceeding the target voting power plus 0.5%, Mr. Malone and the JCM Trust will be required to transfer shares of Liberty Broadband Series B common stock owned by them to Liberty Broadband in exchange for an equal number of shares of Liberty Broadband Series C common stock, but only as necessary in order to preserve the target voting power. These transferred shares of Liberty Broadband Series B common stock would increase the number of waived B shares for purposes of the exchange agreement.

        In addition, upon certain fundamental events resulting in holders of Liberty Broadband Series B common stock receiving securities of Liberty Broadband, securities of another person, property or cash

or a combination thereof, then either, at Liberty Broadband's sole discretion (as approved by a majority of its independent directors), (x) Liberty Broadband will provide for Mr. Malone or the JCM Trust to receive the same per share amount and form of consideration to be received by holders of Liberty Broadband Series B common stock on such event for his or its shares of Liberty Broadband Series C common stock (up to the number of waived B shares) or (y) in connection with certain such events, Mr. Malone will receive all remaining waived B shares in exchange for an equal number of shares of Liberty Broadband Series C common stock.

        For more information, please see “Special Factors—Other Agreements Related to the Combination—Exchange Agreement.”

        Subject to certain conditions, Mr. Malone and certain members of the Malone Group have granted the Chief Legal Officer of Liberty Broadband and GCI Liberty an irrevocable proxy to vote their respective shares of Liberty Broadband common stock in accordance with the Liberty Broadband voting agreement.

•

against any action, proposal, transaction, agreement or amendment of GCI Liberty's restated certificate of incorporation (the “GCI Liberty charter”) or its amended and restated bylaws (the “GCI Liberty bylaws”), in each case, that would reasonably be expected to (1) result in a breach of any covenant, representation or warranty or any other obligation or agreement of GCI Liberty contained in the merger agreement, or of Mr. Malone and certain members of the Malone Group contained in the GCI Liberty voting agreement for which Mr. Malone and those certain members of the Malone Group have received prior notice from GCI Liberty or Liberty Broadband that it reasonably expects that such action or proposal would result in such a breach, or (2) prevent, impede, interfere with, delay, postpone or adversely affect the consummation of the transactions contemplated by the merger agreement.

        Subject to certain conditions, Mr. Malone and certain members of the Malone Group have granted the Chief Legal Officer of Liberty Broadband and GCI Liberty an irrevocable proxy to vote their respective shares of GCI Liberty capital stock in accordance with the GCI Liberty voting agreement.
