ARRAY DIGITAL INFRASTRUCTURE, INC.

In November 2009, UScellular announced by Form 8-K that the Board of Directors of UScellular authorized the repurchase of up to 1,300,000 additional Common Shares on an annual basis beginning in 2009 and continuing each year thereafter, on a cumulative basis. In December 2016, the UScellular Board amended this authorization to provide that, beginning on January 1, 2017, the increase in the authorized repurchase amount with respect to a particular year will be any amount from zero to 1,300,000 Common Shares, as determined by the Pricing Committee of the Board of Directors, and that if the Pricing Committee did not specify an additional amount for any year, such additional amount would be zero for such year. The Pricing Committee has not specified any increase in the authorization since that time. The Pricing Committee also was authorized to decrease the cumulative amount of the authorization at any time, but has not taken any action to do so at this time. The authorization provides that share repurchases will be made pursuant to open market purchases, block purchases in compliance with Rule 10b-18 of the Exchange Act or Rule 10b5-1 of the Exchange Act, or pursuant to accelerated share repurchase arrangements, prepaid share repurchases, private purchases, or otherwise, depending on market prices and other conditions. This authorization does not have an expiration date. UScellular did not determine to terminate the foregoing Common Share repurchase program, as amended, or cease making further purchases thereunder, during the first quarter of 2025.

The following table provides certain information with respect to all purchases made by or on behalf of UScellular, or any open market purchases made by any "affiliated purchaser" (as defined by the SEC) of UScellular, of UScellular Common Shares during the quarter covered by this Form 10-Q. The purchases below were made under a Rule 10b5-1 stock repurchase plan, which terminated on March 31, 2025.
