Basis of Presentation	(1) Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of Liberty Broadband Corporation (“Liberty Broadband,” the “Company,” “us,” “we,” or “our” unless the context otherwise requires). Liberty Broadband is primarily comprised of an equity method investment in Charter Communications, Inc. (“Charter”). Liberty Broadband and its subsidiaries completed an internal reorganization preceding the GCI Divestiture (as defined below) to transfer the GCI Business (as defined below) to GCI Liberty, Inc. (“GCI Liberty”). Following the internal reorganization, GCI Liberty owns, directly or indirectly, GCI, LLC and the operations comprising, and the entities that conduct, the GCI Business (collectively, “GCI”). GCI Liberty was a wholly owned subsidiary of Liberty Broadband until the GCI Divestiture, which was completed on July 14, 2025. GCI Liberty is presented as a discontinued operation in the Company’s condensed consolidated financial statements. See note 2 for details of the GCI Divestiture. On December 18, 2020, the original GCI Liberty, Inc. (“prior GCI Liberty”), the previous parent company of GCI, was acquired by Liberty Broadband. The accompanying (a) condensed consolidated balance sheet as of December 31, 2024, which has been derived from audited financial statements, and (b) interim unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the results for such periods have been included. The results of operations for any interim period are not necessarily indicative of results for the full year. Additionally, certain prior period amounts have been reclassified for comparability with current period presentation. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in Liberty Broadband's Annual Report on Form 10-K for the year ended December 31, 2024. All significant intercompany accounts and transactions have been eliminated in the condensed consolidated financial statements. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Company considers (i) the application of the equity method of accounting for its affiliate, (ii) non-recurring fair value measurements of non-financial instruments and (iii) accounting for income taxes to be its most significant estimates. Through a number of prior years’ transactions, Liberty Broadband has acquired an interest in Charter. The investment in Charter is accounted for using the equity method. Liberty Broadband does not control the decision making process or business management practices of this affiliate. Accordingly, Liberty Broadband relies on the management of this affiliate to provide it with accurate financial information prepared in accordance with GAAP that the Company uses in the application of the equity method. In addition, Liberty Broadband relies on audit reports that are provided by the affiliate's independent auditor on the financial statements of such affiliate. The Company is not aware, however, of any errors in or possible misstatements of the financial information provided by its equity affiliate that would have a material effect on Liberty Broadband's condensed consolidated financial statements. Recent Events On November 12, 2024, the Company entered into a definitive agreement (the “Merger Agreement”) under which Charter has agreed to acquire Liberty Broadband (the “Combination”, together with the other transactions contemplated by the Merger Agreement, the “Transactions”). At the special meeting held on February 26, 2025, the requisite holders of Liberty Broadband’s Series A common stock (“LBRDA”), Series B common stock (“LBRDB”) and Series A cumulative redeemable preferred stock (“Liberty Broadband preferred stock”) approved the adoption of the Merger Agreement, pursuant to which, among other things, Liberty Broadband will combine with Charter and divest the business of GCI (the “GCI Business”). As discussed above, as a condition to closing the Combination, Liberty Broadband agreed to divest the GCI Business by way of a distribution to the holders of Liberty Broadband common stock (the “GCI Divestiture”), which was completed on July 14, 2025. The GCI Divestiture was taxable to Liberty Broadband and its stockholders, with Charter bearing the corporate level tax liability upon completion of the Combination. If such corporate level tax liability exceeded $420 million, Liberty Broadband (and Charter upon completion of the Combination) would be entitled under a tax receivables agreement to the portion of the tax benefits realized by GCI Liberty corresponding to such excess; however, the corporate level tax liability from the GCI Divestiture is estimated to be significantly less than $420 million. In addition, in connection with the entry into the Merger Agreement, Charter, Liberty Broadband and Advance/Newhouse Partnership (“A/N”) entered into an amendment (the “Stockholders and Letter Agreement Amendment”) to (i) that certain Second Amended and Restated Stockholders Agreement, dated as of May 23, 2015 (as amended, the “Stockholders Agreement”), by and among Charter, Liberty Broadband, and A/N, and (ii) that certain Letter Agreement, dated as of February 23, 2021 (the “Letter Agreement”), by and between Charter and Liberty Broadband. Details of this agreement are further described in note 5. On May 16, 2025, Charter and Cox Communications (“Cox”) announced that they entered into a definitive agreement to combine their businesses. In connection with this transaction, Liberty Broadband has agreed to accelerate the closing of its acquisition by Charter to occur contemporaneously with Charter’s combination with Cox. There are no changes to any other transaction terms of the pending Liberty Broadband and Charter transaction. During the nine months ended September 30, 2025, we did not repurchase any shares of Liberty Broadband common stock, which is currently restricted by the Merger Agreement. During the nine months ended September 30, 2024, we repurchased 1.1 million shares of Liberty Broadband Series C common stock (“LBRDK”) for a total purchase price of $89 million. As of September 30, 2025, the amount remaining under the authorized repurchase program is approximately $1,685 million, which is currently restricted by the Merger Agreement. In connection with the GCI Divestiture, Martin E. Patterson was appointed to the role of President and Chief Executive Officer of Liberty Broadband, effective July 14, 2025. Upon effectiveness of Mr. Patterson’s appointment, John C. Malone resigned as President and Chief Executive Officer but remains Chairman of the Board. Exchange Agreement with Chairman On June 13, 2022, Liberty Broadband entered into an Exchange Agreement with its Chairman of the board of directors, John C. Malone, and a revocable trust of which Mr. Malone is the sole trustee and beneficiary (the “JM Trust”) (the “Exchange Agreement”). Under the Exchange Agreement and the Malone exchange side letter (described below), the JM Trust has exchanged 2,098,189 total shares of LBRDB for the same number of LBRDK as of September 30, 2025. On November 12, 2024, in connection with the entry into the Merger Agreement, Liberty Broadband entered into the Malone exchange side letter with Mr. Malone and certain trusts related to Mr. Malone (collectively, the “Malone Exchange Holders”), whereby, among other things, the Malone Exchange Holders agreed to an arrangement under which Liberty Broadband had the right, in connection with the GCI Divestiture, to exchange certain shares of LBRDB held by such Malone Exchange Holders for shares of LBRDK on a one-for-one basis (the “Malone exchange”) to avoid the application of certain related party rules that otherwise could limit the availability of certain tax benefits to the divested GCI entity following the GCI Divestiture. If the Merger Agreement is terminated without the completion of the Combination having occurred but following the consummation of the Malone exchange (the “Malone exchange closing”), and unless otherwise agreed to in writing by the Malone Exchange Holders and Liberty Broadband, the Malone exchange will be automatically rescinded and treated as if neither the Malone exchange nor the Malone exchange closing had ever occurred. Further, pursuant to the terms of the Malone exchange side letter, the parties thereto amended certain provisions of the Exchange Agreement to provide that (i) solely in connection with the GCI Divestiture, Malone Series C Exchangeable Shares (as defined in the Exchange Agreement) would not be exchanged for shares of LBRDB and the holders of such Malone Series C Exchangeable Shares would receive the same per share consideration received by holders of shares of LBRDK, (ii) Liberty Broadband waived its right to obligate the Malone Exchange Holders to enter into an exchange agreement with the divested GCI entity in connection with the GCI Divestiture, (iii) the Exchange Agreement would not be terminated as a result of the Malone Exchange Holders falling below 20% voting power in connection with the GCI Divestiture, and (iv) following the Malone exchange and prior to any termination of the Merger Agreement, none of the Malone Series C Exchangeable Shares would be exchanged for shares of LBRDB. In accordance with the Malone exchange side letter and concurrent with the GCI Divestiture, the Malone Exchange Holders exchanged 1,617,040 shares of LBRDB for 1,617,040 shares of LBRDK on July 14, 2025. Historical Spin-Off Arrangements During May 2014, the board of directors of Liberty Media Corporation and its subsidiaries (“Liberty”) authorized management to pursue a plan to spin-off to its stockholders common stock of a wholly owned subsidiary, Liberty Broadband, and to distribute subscription rights to acquire shares of Liberty Broadband’s common stock (the “Broadband Spin-Off”). In connection with the Broadband Spin-Off, Liberty and Liberty Broadband entered into certain agreements in order to govern certain of the ongoing relationships between the two companies and to provide for an orderly transition, including a tax sharing agreement, services agreement and a facilities sharing agreement. Additionally, in connection with a prior transaction, prior GCI Liberty and QVC Group, Inc., formerly Qurate Retail, Inc. (“QVC Group”) entered into a tax sharing agreement, which was assumed by Liberty Broadband as a result of the combination of prior GCI Liberty and Liberty Broadband. The tax sharing agreement provides for the allocation and indemnification of tax liabilities and benefits between QVC Group and Liberty Broadband and other agreements related to tax matters. Under the facilities sharing agreement, Liberty Broadband shares office space with Liberty and related amenities at Liberty’s corporate headquarters. Pursuant to the services agreement, Liberty provides Liberty Broadband with general and administrative services including legal, tax, accounting, treasury, information technology, cybersecurity and investor relations support. Liberty Broadband reimburses Liberty for direct, out-of-pocket expenses incurred by Liberty in providing these services which are negotiated semi-annually, as necessary. Under these various agreements, amounts reimbursable to Liberty were approximately $2 million and $2 million for the three months ended September 30, 2025 and 2024, respectively, and $7 million and $5 million for the nine months ended September 30, 2025 and 2024, respectively. Liberty Broadband had a tax sharing receivable with QVC Group of approximately $10 million and $20 million as of September 30, 2025 and December 31, 2024, respectively, included in Other assets in the condensed consolidated balance sheets. New Accounting Pronouncements Not Yet Adopted In September 2025, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”), which amends certain aspects of the accounting for and disclosure of software costs under Subtopic 350-40. The amendments improve the operability of the guidance by removing all references to software development project stages so that the guidance is neutral to different software development methods, including methods that entities may use to develop software in the future. ASU 2025-06 is effective for annual periods beginning after December 15, 2027 (year ending December 31, 2028 for the Company). The Company is currently evaluating the impact the adoption of ASU 2025-06 will have on its consolidated financial statements.
