The information contained in Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following information: On May 16, 2025, the Issuer entered into a Transaction Agreement (the "Cox Transaction Agreement") with Cox Enterprises, Inc. ("Cox"), and Charter Communications Holdings, LLC, pursuant to which, among other things, the Issuer will acquire the Cabot Business (as defined in the Cox Transaction Agreement) from Cox in a series of transactions described therein (the "Cox Transactions"). In connection with the Cox Transactions, the Reporting Person has agreed to enter into certain ancillary agreements pursuant to which (1) the closing of the Reporting Person's pending transaction with the Issuer ("Liberty Closing") would accelerate in connection with the closing of the Cox Transactions or, at the Reporting Person's election, the termination of the Cox Transaction Agreement and (2) the Reporting Person would agree to provide its voting support for the Cox Transactions, in each case as described in more detail below. In connection with the Issuer's entry into the Cox Transaction Agreement, on May 16, 2025, the Reporting Person, the Issuer, Merger LLC and Merger Sub entered into a side letter (the "Side Letter"), pursuant to which, among other things, the parties agreed to accelerate the date of the Liberty Closing, as contemplated by the Merger Agreement, to occur on the earlier of (a) immediately prior to the closing of the Cox Transactions, (b) the later of (i) June 30, 2027 and (ii) the third (3rd) business day after all conditions set forth in Article VI of the Merger Agreement have been satisfied or waived (to the extent waivable), or at such other date and time as agreed to by the parties in writing or pursuant to Section 5.11(f) of the Merger Agreement and (c) solely if the Cox Transaction Agreement is terminated in accordance with its terms (the "Cox Transaction Termination"), at the Reporting Person's election, the later of (i) the tenth (10th) business day after the Cox Transaction Termination and (ii) the third (3rd) business day after all conditions set forth in the Merger Agreement shall have been satisfied or waived (to the extent waivable), or at such other date and time as agreed to by the parties in writing or pursuant to Section 5.11(f) of the Merger Agreement. In addition, the Reporting Person has agreed to cause each of its director designees serving on the board of directors of the Issuer to resign, with such resignation conditioned on the occurrence of, and effective as of immediately prior to, the effective time of the Liberty Closing. Further, in connection with the Issuer's entry into the Cox Transaction Agreement, on May 16, 2025, the Reporting Person, the Issuer and Cox entered into a voting agreement (the "Voting Agreement"), pursuant to which the Reporting Person has committed to vote all shares of Common Stock beneficially owned by the Reporting Person as of the applicable record date for the applicable meeting, in favor of, among other things, the Certificate of Amendment (as defined in the Cox Transaction Agreement) and the Cabot Parent Issuance (as defined in the Cox Transaction Agreement); except that in the event that the board of directors of the Issuer changes its recommendation, then the Reporting Person will only be obligated to vote such shares of Common Stock held by the Reporting Person equal in the aggregate to 20.0% of the total voting power of the Common Stock and the Issuer's Class B common stock (on an as-exchanged basis) (the "Covered Shares"), in favor thereof, and any shares that are not Covered Shares may be voted in the Reporting Person's discretion (other than Proportional Voting Shares, which are addressed below). The foregoing voting obligations will not apply to shares of Common Stock beneficially owned by the Reporting Person that exceed the voting cap applicable to the Reporting Person under the Stockholders Agreement (such shares, the "Proportional Voting Shares"), which Proportional Voting Shares, pursuant thereto, must be voted in the same proportion as all other votes cast with respect to the applicable matter (such proportion determined without inclusion of the votes cast by the Reporting Person, A/N and other persons that beneficially own 10% or more of the total voting power of the Issuer). The foregoing descriptions of the Side Letter and the Voting Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of the Side Letter and the Voting Agreement, respectively, which are included as Exhibit 7(gg) and Exhibit 7(hh) of this Amendment, respectively, and are incorporated into this Item 4 by reference. In addition, for further information on the Side Letter and Voting Agreement, see the Current Report on Form 8-K filed by the Reporting Person on May 19, 2025.
