Also on December 29, 2025, the Issuer, Charter Communications Holding Company, LLC ("Charter") and Pine Investor, LLC ("Pine" and, together with the Reporting Person and Charter, referred to herein collectively as the "Stockholders") entered into the previously disclosed Second Amended and Restated Stockholders Agreement (the "Second Amended and Restated SHA") and the Issuer entered into the previously disclosed amendment to its Registration Rights Agreement, dated as of March 10, 2021, by and among the Issuer and the other parties thereto (such amendment, the "RRA Amendment").

The full text of the Second Amended and Restated SHA and the RRA Amendment are included as Exhibit 7(d) and Exhibit 7(e) hereto, respectively, and are incorporated herein by reference.

The shares of Common Stock beneficially owned by the Reporting Person and described in this Statement are being held by the Reporting Person for investment purposes.

Notwithstanding the foregoing, the Reporting Person may determine to change its intentions with respect to the Issuer at any time in the future and may, for example, elect (i) to acquire additional securities of the Issuer in open market or privately negotiated transactions or (ii) to dispose of all or a portion of the Reporting Person's holdings of securities of the Issuer. In reaching any determination as to its future course of action, the Reporting Person will take into consideration various factors, such as the Issuer's business and prospects, other developments concerning the Issuer, other business opportunities available to the Reporting Person, tax considerations, liquidity needs and general economic and stock market conditions, including, but not limited to, the market prices of the securities.
