This Item 4 is being updated by the following information. On September 1, 2026, TDS issued a press release (the "Press Release") announcing that it is no longer pursuing the acquisition of the Array Common Shares that it does not already own and has withdrawn its previously disclosed proposal. Under the terms of that proposal, each Array Common Share not already owned by TDS would have been exchanged for 0.86 of a TDS Common Share, subject to the assumptions set forth in the proposal. TDS will retain its approximately 82% ownership interest in Array. A copy of the Press Release is filed herewith as Exhibit 2. TDS may in the future recommence its efforts to acquire the Array Common Shares it does not own or pursue other potential transactions involving TDS and Array and may, from time to time, acquire additional Array Common Shares or engage in discussions with Array or members of its Board of Directors regarding any such transactions. The trustees of the Voting Trust have advised TDS that they intend to maintain the ability to keep or dispose of the voting control of TDS. The trustees of the Voting Trust have further advised TDS that the trustees of the Voting Trust intend that TDS maintain the ability to keep or dispose of the voting control of the Issuer. TDS and the trustees of the Voting Trust also retain the right to change their intent, to acquire additional securities from time to time or to dispose of all or part of the securities beneficially owned by TDS or the Voting Trust in any manner permitted by the terms of the Voting Trust and/or applicable law. Except as disclosed or incorporated by reference herein, TDS and the Voting Trust do not have any current intention, plan or proposal with respect to any of the matters specified in paragraphs (a) through (j) of Item 4 of Schedule 13D.
