Sources of Liquidity

TDS believes that existing cash and investment balances, dividends, distributions from unconsolidated entities, expected cash flows from operating activities and funds available under its financing agreements will provide sufficient liquidity for TDS to meet its funding needs. TDS requires funding for, among other uses, day-to-day operations, capital expenditures, fiber deployments and E-ACAM builds, payment of dividends, debt service requirements, repurchases of shares and potential acquisitions of land, land easements or additional towers.

Cash and Cash Equivalents

Cash and cash equivalents include cash and money market investments. TDS does not have direct access to Array cash.

In the second quarter of 2026, Array closed on various sales of certain wireless spectrum licenses to Verizon and T-Mobile for total proceeds of $1,167.6 million and expects a cash income tax liability on the transactions of approximately $170.0 million, most of which will be paid during the third quarter of 2026.

Cash and Cash Equivalents

The majority of TDS’ Cash and cash equivalents are held in money market funds that purchase only debt issued by the U.S. Treasury or U.S. government agencies and bank deposit accounts. Refer to the Consolidated Cash Flow Analysis for additional information related to changes in Cash and cash equivalents.

Financing

Revolving Credit Agreements

TDS and Array have unsecured revolving credit agreements with maximum borrowing capacities of $400.0 million and $100.0 million, respectively. Amounts under the agreements may be borrowed, repaid and reborrowed from time to time until maturity in December 2030. As of June 30, 2026, there were no outstanding borrowings under the agreements, except for letters of credit, and TDS' and Array's unused borrowing capacity was $399.5 million and $99.9 million, respectively.

Debt Covenants

The TDS and Array revolving credit agreements and the Array term loan agreement with CoBank require TDS or Array, as applicable, to comply with certain affirmative and negative covenants, which include certain financial covenants that may restrict the borrowing capacity available. TDS and Array are required to maintain a Consolidated Leverage Ratio, as defined in the agreements, as of the end of any fiscal quarter at a level not to exceed 3.50 to 1.00. TDS and Array are also required to maintain the Consolidated Interest Coverage Ratio at a level not lower than 3.00 to 1.00 as of the end of any fiscal quarter. TDS and Array believe that they were in compliance as of June 30, 2026 with all such financial covenants.

Capital Expenditures

TDS makes substantial investments to acquire, construct and upgrade telecommunications networks and facilities to remain competitive and as a basis for creating long-term value for shareholders. In recent years, changes in technology have required substantial investments in TDS’ networks to remain competitive; this is expected to continue in 2026 and future years with the continued deployment of fiber for TDS Telecom.

Capital expenditures for continuing operations (i.e., additions to property, plant and equipment), which include the effects of accruals and capitalized interest, for the six months ended June 30, 2026 and 2025, were as follows:

Capital Expenditures

TDS Telecom’s capital expenditures for the six months ended June 30, 2026 and 2025, were $305.2 million and $149.1 million, respectively.

Capital expenditures for the full year 2026 are expected to be between $625.0 million and $675.0 million. These expenditures are expected to be used principally for the following purposes:

▪Continue fiber deployment in expansion markets and to meet E-ACAM build-out requirements;

▪Support broadband growth and success-based spending; and

▪Maintain and enhance existing infrastructure.

Array's capital expenditures for the six months ended June 30, 2026 and 2025, were $12.5 million and $9.1 million, respectively.

Array's capital expenditures for 2026 are expected to be between $25.0 million and $35.0 million. These capital expenditures are expected to be used for purchases of land interests which are opportunistic in nature, tower maintenance, tower builds and one-time costs of migrating the tower light monitoring function to Array's long-term solution.

TDS intends to finance its capital expenditures for 2026 using existing cash balances and cash flows from operating activities.

Acquisitions and Divestitures

TDS is engaged and may in the future be engaged in negotiations (subject to all applicable regulations) relating to the acquisition or divestiture of companies, properties and assets. In general, TDS does not disclose such transactions until there is a definitive agreement.
