Potential Recapitalization Transaction with Preferred Stockholders On September 26, 2025, the Company entered into separate Stock Exchange Agreements (the "Exchange Agreements") with each of Charter Communications Holding Company, LLC ("Charter"), Liberty Broadband Corporation ("Liberty"), and Pine Investor, LLC ("Pine," and together with Charter and Liberty, the "Preferred Stockholders"), pursuant to which, at the closing of the transactions contemplated thereby (the "Closing"), each Preferred Stockholder will exchange the 31,928,301 shares of Series B Convertible Preferred Stock, par value $0.001 per share, of the Company (the "Preferred Stock") currently owned by such Preferred Stockholder for (i) 4,223,621 shares of a new series of convertible preferred stock to be designated as Series C Convertible Preferred Stock, par value $0.001 per share ("Series C Preferred Stock"), which will be convertible into shares of common stock, par value $0.001 per share, of the Company ("Common Stock") and (ii) 3,286,825 shares of Common Stock (such transactions, collectively, the "Exchange"). The Closing is subject to various closing conditions, including approval by the Company's stockholders. The Company currently intends to hold a special meeting of stockholders in December 2025 to seek approval of the Exchange and related matters and, if approved, to complete the Closing shortly thereafter. If the Exchange is consummated, the Company will retire the shares of Preferred Stock acquired by the Company pursuant to the Exchange Agreements and will eliminate from its Amended and Restated Certificate of Incorporation all matters set forth in the Certificate of Designations of the Preferred Stock, including the annual dividend rights provided therein. In addition, the Company and the Preferred Stockholders will enter into an amended and restated stockholders agreement that, among other things, will eliminate the Preferred Stockholders' current right to a special dividend of at least $47.0 million. The Exchange Agreements include certain termination rights for the Company and each of the Preferred Stockholders. In addition, the Exchange Agreements contain customary representations and warranties from the Preferred Stockholders and the Company, and each party has agreed to certain covenants. Each party has also agreed, on behalf of itself and certain related parties, to a release of claims relating to the ownership and transfer of the existing shares of Preferred Stock, subject to certain exceptions. Provided that the Closing occurs, the Company has agreed to make a one-time cash payment of $2.0 million to each of the Preferred Stockholders on June 30, 2028, regardless of whether the Preferred Stockholder continues to own any securities of the Company on such date. On September 26, 2025, in connection with the execution of the Exchange Agreements, the Company entered into an amendment to its senior secured financing agreement, dated as of December 31, 2024, among the Company as borrower, each subsidiary of the Company from time to time party thereto as a guarantor, each lender from time to time party thereto, and Blue Torch Finance LLC, as administrative agent and collateral agent (the "Credit Agreement") to permit the Exchange and the issuance of Series C Preferred Stock in connection with the Exchange.
