Item 7.01. Regulation FD Disclosure

In connection with, and in furtherance of, the previously announced spin-off of GCI Liberty, Inc., a Nevada corporation (“GCI Liberty”), from Liberty Broadband Corporation, a Delaware corporation (“Liberty Broadband”), on May 5, 2025, Liberty Broadband entered into a Series A Preferred Stock Purchase Agreement (the “Purchase Agreement”) with GCI Liberty, and each of Janus Henderson Income ETF, a series of the Detroit Street Trust, a Delaware Business Trust, and Janus Henderson Multi-Sector Income Fund, a series of the Janus Investment Fund, a Massachusetts Business Trust (collectively, the “Buyers”), whereby, subject to the terms thereof, Liberty Broadband will sell 10,000 shares of GCI Liberty’s 12% Series A Cumulative Redeemable Non-Voting Preferred Stock, par value $0.01 per share (the “Shares”), to the Buyers in exchange for $10 million (the “Transaction”).

The closing of the Transaction is conditioned on, among other things, the satisfaction (or, if permissible, waiver) of (i) the absence of any order or law prohibiting the consummation of the Transaction and (ii) the completion of an internal reorganization of Liberty Broadband and GCI Liberty, pursuant to which Liberty Broadband will transfer certain assets, including 100% of the outstanding equity interests in GCI, LLC, to GCI Liberty in exchange for GCI Liberty stock, including the Shares, and the assumption of certain liabilities (collectively, the “Reorganization”). In connection with such Reorganization, GCI Liberty will file a Certificate of Designations with the Secretary of State of the State of Nevada setting forth the rights, preferences and privileges of the Shares (the “Certificate of Designations”).

The Shares will be subject to, among other things, mandatory redemption on the date that is seven years after the date the Shares are first issued (the “Scheduled Redemption Date”) to Liberty Broadband in the Reorganization (the “Original Issuance Date”) at a price equal to the liquidation price plus all unpaid dividends (whether or not declared) on such shares accrued from (and including) the most recent dividend payment date to (but not including) (i) the Scheduled Redemption Date or (ii) in the case of Shares that remain outstanding following the Scheduled Redemption Date, the date on which such shares are redeemed pursuant to the Certificate of Designations. As of any date of determination, the “liquidation price” of each Share is equal to the sum of (i) $1,000, plus (ii) all accrued and unpaid dividends (whether or not declared) that have been added to and then remain part of the liquidation price as of such date pursuant to the Certificate of Designations.

At the option of GCI Liberty by action of the board of directors of GCI Liberty, on or after the fifth anniversary of the Original Issuance Date and prior to the Scheduled Redemption Date, GCI Liberty may redeem all or a portion of the outstanding Shares (an “Optional Redemption”), at a price per share equal to the sum of the liquidation price plus all unpaid dividends (whether or not declared) accrued from (and including) the most recent dividend payment date but not including the date of such Optional Redemption.
