Telephone and Data Systems Announces It Is No Longer Pursuing the Acquisition of Public Shares of Array Digital Infrastructure

TDS Expects to Recommence Repurchase Program

CHICAGO, Sept. 1, 2026 /PRNewswire/ — Telephone and Data Systems, Inc. (NYSE: TDS) (the “Company” or “TDS”) today announced that it is no longer pursuing the acquisition of the Common Shares of Array Digital Infrastructure, Inc. (NYSE: AD) (“Array”) that it does not already own and has withdrawn its previously announced proposal. Under the terms of the proposal, each Array Common Share not 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 continue to hold its approximately 82% ownership interest in Array.

“While we remain confident that the combination presents substantial benefits, we no longer believe that now is the right time to complete such a transaction. Despite extensive review on both sides, we were not able to reach agreement on the form of consideration and value,” said Walter Carlson, President and Chief Executive Officer of TDS. “We appreciate the time and effort that the Special Committee of the Board of Directors of Array devoted to this process. We remain confident in Array’s business and long-term prospects and are committed to supporting Array’s continued success as a leading owner and operator of wireless communications infrastructure. Similarly, we remain confident in the long-term prospects of TDS Telecom as we execute our strategy to expand our marketable fiber service footprint and deliver value for customers and our shareholders.”

TDS continues to support Array’s previously disclosed intention to opportunistically monetize its remaining wireless spectrum assets. TDS and Array intend in the near term to increase their efforts to pursue opportunities to monetize such assets.

With the withdrawal of the proposal to Array, TDS expects to recommence repurchases of TDS Common Shares under its previously announced share repurchase programs, including the additional $500 million share repurchase authorization announced in November 2025. As of June 30, 2026, approximately $523.9 million remained available under TDS’s share repurchase programs. The timing, manner and amount of any repurchases will be determined by TDS in its discretion and will depend on market conditions, applicable legal requirements and other factors.
