Executive Overview

The following Management’s Discussion and Analysis (MD&A) should be read in conjunction with the audited consolidated financial statements and notes of Telephone and Data Systems, Inc. (TDS) for the year ended December 31, 2024, and with the description of TDS’ business included herein. Certain numbers included herein are rounded to millions for ease of presentation; however, certain calculated amounts and percentages are determined using the unrounded numbers.

This report contains statements that are not based on historical facts, which may be identified by words such as “believes,” “anticipates,” “estimates,” “expects,” “plans,” “intends,” “projects,” “will” and similar expressions. These statements constitute and represent “forward looking statements” as this term is defined in the Private Securities Litigation Reform Act of 1995. Such forward looking statements involve known and unknown risks, uncertainties and other factors that may cause actual results, events or developments to be significantly different from any future results, events or developments expressed or implied by such forward looking statements. See the disclosure under the heading Private Securities Litigation Reform Act of 1995 Safe Harbor Cautionary Statement elsewhere in this report for additional information.

The accounting policies of TDS conform to accounting principles generally accepted in the United States of America (GAAP). However, TDS uses certain “non-GAAP financial measures” in the MD&A and the business segment information. A discussion of the reasons TDS determines these metrics to be useful and reconciliations of these measures to their most directly comparable measures determined in accordance with GAAP are included in the disclosure under the heading Supplemental Information Relating to Non-GAAP Financial Measures within the MD&A of this report.

General

TDS is a diversified telecommunications company that provides high-quality communications services to approximately 5.5 million connections nationwide. TDS provides wireless services and leases tower space to third-party carriers on owned towers through its 83%-owned subsidiary, United States Cellular Corporation (UScellular). TDS also provides broadband, video, voice and wireless services through its wholly-owned subsidiary, TDS Telecommunications LLC (TDS Telecom). TDS operates entirely in the United States.

During the second quarter of 2024, TDS and UScellular modified their reporting structure due to the planned disposal of the UScellular wireless operations and, as a result, disaggregated the UScellular operations into two reportable segments – Wireless and Towers. This presentation reflects how TDS' and UScellular's chief operating decision maker allocates resources and evaluates operating performance following this strategic shift. Prior periods have been updated to conform to the new reportable segments. See Note 20 — Business Segment Information in the Notes to Consolidated Financial Statements for additional information about TDS' segments.

TDS Mission and Strategy

TDS’ mission is to provide outstanding communications services to its customers and meet the needs of its shareholders, its people, and its communities. In pursuing this mission, TDS seeks to grow its businesses, create opportunities for its associates, support the communities it serves, and build value over the long term for its shareholders. Since its founding, TDS has been committed to bringing high-quality communications services to rural and underserved communities. TDS continues to make progress on developing and enhancing its Environmental, Social and Governance (ESG) program, including the publication of the most recent TDS ESG Report in August 2024, which is available on the TDS website.

TDS’ historical long-term strategy has been to re-invest the majority of its operating capital in its businesses to strengthen their competitive positions and financial performance, while also returning value to TDS shareholders primarily through the payment of a regular quarterly cash dividend. In the second quarter of 2024, TDS reset its approach to capital allocation and declared dividends in the second, third, and fourth quarters of 2024 at approximately 20% of the first quarter of 2024 dividend for TDS Common and Series A shares. This shift in approach is expected to free up additional capital that can be used to support TDS' fiber program, among other purposes. It is uncertain at this time how the outcome of the ongoing strategic alternatives review process for UScellular, TDS' available opportunities to reinvest in its businesses, or TDS' ongoing liquidity needs, may impact the decisions of the TDS Board of Directors regarding the declaration of future dividends.

Announced Transactions and Strategic Alternatives Review

On August 4, 2023, TDS and UScellular announced that the Boards of Directors of both companies decided to initiate a process to explore a range of strategic alternatives for UScellular. On May 28, 2024, UScellular announced that its Board of Directors unanimously approved the execution of a Securities Purchase Agreement (Securities Purchase Agreement) by and among TDS, UScellular, T-Mobile US, Inc. (T-Mobile) and USCC Wireless Holdings, LLC, pursuant to which, among other things, UScellular agreed to sell its wireless operations and select spectrum assets to T-Mobile for a purchase price, subject to adjustments, as specified in the Securities Purchase Agreement, of $4,400 million, which is payable in a combination of cash and the assumption of up to approximately $2,000 million in debt. The purchase price includes $100 million contingent on the satisfaction of certain financial and operational metrics. The purchase price also includes $400 million allocated to certain wireless spectrum licenses held by entities in which UScellular is a non-controlling limited partner. The closing with respect to these wireless spectrum licenses is contingent upon UScellular's purchase, which is pending receipt of regulatory approval, of the remaining equity in the entities that UScellular does not currently own. The Securities Purchase Agreement also contemplates, among other things, a Short-Term Spectrum Manager Lease Agreement and Short-Term Spectrum Manager Sublease Agreements that will become effective at the closing date, which provide T-Mobile with an exclusive license to use certain UScellular spectrum assets and leases at no cost for up to one-year for the sole purpose of providing continued, uninterrupted service to customers. The sale of the wireless business to T-Mobile is expected to close in mid-2025, subject to the receipt of regulatory approvals and the satisfaction of customary closing conditions.

To effect the disposition and wind down of the wireless operations in accordance with the terms of the Securities Purchase Agreement, UScellular expects that if the closing of the transaction were to occur that such closing will trigger or accelerate the recognition of certain cash and non-cash obligations. Such obligations include contingent advisory fees, employee compensation and severance, employee stock award costs, debt extinguishment, income tax expense, administrative costs, restructuring expenses and other wind down costs. UScellular also expects to incur significant decommissioning costs for certain towers that UScellular elects to retire, and such decommissioning costs are also expected to include remaining obligations under related ground leases. These costs are expected to have a significant impact on TDS' financial statements.

On October 17, 2024, UScellular, and certain subsidiaries of UScellular, entered into a License Purchase Agreement (Verizon Purchase Agreement) with Verizon Communications Inc. (Verizon) to sell certain AWS, Cellular and PCS wireless spectrum licenses and agreed to grant Verizon certain rights to lease such licenses prior to the transaction close for total proceeds of $1,000 million. As of December 31, 2024, UScellular's book value of the wireless spectrum licenses to be sold was $586 million. The transaction is subject to regulatory approval and other customary closing conditions, and is contingent on the closing of the T-Mobile transaction and the termination of the T-Mobile Short-Term Spectrum Manager Lease Agreement.

On November 6, 2024, UScellular, and certain subsidiaries of UScellular, entered into a License Purchase Agreement (AT&T Purchase Agreement) with New Cingular Wireless PCS, LLC (AT&T), a subsidiary of AT&T Inc. to sell certain 3.45 GHz and 700 MHz wireless spectrum licenses and agreed to grant AT&T certain rights to lease and sub-lease such licenses prior to the transaction close for total proceeds of $1,018 million, subject to certain purchase price adjustments. As of December 31, 2024, UScellular's book value of the wireless spectrum licenses to be sold was $859 million. The transaction is subject to regulatory approval and other customary closing conditions and substantially all of the licenses subject to the transaction are contingent on the closing of the T-Mobile transaction. The purchase price includes $232 million allocated to certain wireless spectrum licenses that are held by an entity in which UScellular is a non-controlling limited partner. The closing with respect to these wireless spectrum licenses is contingent upon UScellular's purchase, which is pending receipt of regulatory approval, of the remaining equity in the entity that UScellular does not currently own.

The strategic alternatives review process is ongoing as UScellular works toward closing the transactions signed during 2024, including the T-Mobile, Verizon and AT&T transactions and continues to seek to opportunistically monetize its spectrum assets that are not subject to the Securities Purchase Agreement, the Verizon Purchase Agreement, or the AT&T Purchase Agreement.

TDS incurred third-party expenses related to the announced transactions and strategic alternatives review of $56 million and $13 million for the years ended December 31, 2024 and 2023, respectively.

Equity in earnings of unconsolidated entities represents TDS’ share of net income from entities in which it has a noncontrolling interest and that are accounted for using the equity method or the net asset value practical expedient. TDS’ investment in the Los Angeles SMSA Limited Partnership (LA Partnership) contributed pre-tax income of $62 million and $65 million for 2024 and 2023, respectively. See Note 9 — Investments in Unconsolidated Entities in the Notes to Consolidated Financial Statements for additional information.

Interest expense

Interest expense increased in 2024 due primarily to an increase in borrowings under the TDS term loan agreements, partially offset by a decrease in the average principal balance outstanding on the receivables securitization agreement. See Market Risk for additional information regarding maturities of long-term debt and weighted average interest rates.

Income tax expense

Income tax expense decreased in 2024 due primarily to the deferred tax impact of the wireless spectrum license impairment charge recorded in the third quarter of 2024 and a decrease in state tax expense in 2024, partially offset by the deferred tax impact of the Goodwill impairment recorded in the fourth quarter of 2023.

Operating Revenues

(Dollars in millions)

Service revenues consist of:

▪Retail Service – Postpaid and prepaid charges for voice, data and value-added services and cost recovery surcharges

▪Other Service – Amounts received from the Federal USF, inbound roaming, miscellaneous other service revenues and Internet of Things (IoT)

Equipment revenues consist of:

▪Sales of wireless devices and related accessories to new and existing customers, agents, and third-party distributors

Key components of changes in the statement of operations line items were as follows:

2024-2023 Commentary

Total operating revenues

Retail service revenues decreased in 2024 primarily as a result of a decrease in average postpaid and prepaid connections, partially offset by an increase in Postpaid ARPU as previously discussed in the Operational Overview section.

Equipment sales revenues decreased in 2024, due primarily to a decline in smartphone devices sold due to lower upgrades and gross additions, partially offset by a higher average price of new smartphone sales.

Wireless service providers have been aggressive promotionally and on price to attract and retain customers. This includes both traditional carriers and cable wireless companies. UScellular expects promotional aggressiveness by traditional carriers to continue and pricing pressures from cable wireless companies and new entrants to increase into the foreseeable future. Additionally, other larger wireless service providers have more developed networks and coverage as well as lower costs per subscriber than UScellular, which has negatively affected and may continue to negatively affect UScellular's ability to compete over time. Operating revenues and Operating income (loss) have been negatively impacted by these factors in current and prior periods, and are expected to be negatively impacted in future periods.

System operations expenses

System operations expenses decreased in 2024, due primarily to a decrease in expenses driven by the shutdown of the 3G Code Division Multiple Access (CDMA) network in the first quarter of 2024, partially offset by increases in outbound roaming usage and maintenance, utilities, and cell site expenses.

40

Index to MD&A

Cost of equipment sold

Cost of equipment sold decreased in 2024, due primarily to a decline in smartphone devices sold due to lower upgrades and gross additions, partially offset by a higher average cost of new smartphone sales.

Selling, general and administrative expenses

Selling, general and administrative expenses decreased in 2024, due primarily to decreases in various general and administrative and sales related expenses, partially offset by an increase in the strategic alternatives review expenses of $27 million.

Loss on impairment of licenses

Loss on impairment of licenses increased in 2024 due to the wireless spectrum license impairment charge recorded during the third quarter of 2024. See Note 8 — Intangible Assets for a detailed discussion regarding this impairment.

2023-2022 Commentary

Total operating revenues

Retail service revenues decreased in 2023 primarily as a result of a decrease in average postpaid and prepaid connections, partially offset by an increase in Postpaid ARPU as previously discussed in the Operational Overview section.

Other service revenues decreased in 2023, resulting from decreases in inbound roaming revenues, primarily driven by lower data revenues resulting from lower rates.

Equipment sales revenues decreased in 2023, due primarily to a decline in smartphone upgrades and gross additions, partially offset by a higher average price of new smartphone sales.

Total operating expenses

Total operating expenses in 2023 include $9 million of severance and related expenses associated with a reduction in workforce that was recorded in the first quarter of 2023. These severance expenses are included in System operations expenses and Selling, general and administrative expenses.

System operations expenses

System operations expenses decreased in 2023, due primarily to decreases in roaming and customer usage expenses, partially offset by an increase in maintenance, utility, and cell site expenses. The decrease in roaming expense was driven by a decrease in roaming rates partially offset by an increase in usage.

Cost of equipment sold

Cost of equipment sold decreased in 2023, due primarily to a decline in smartphone upgrades and gross additions, partially offset by a higher average cost per unit sold.

Selling, general and administrative expenses

Selling, general and administrative expenses decreased in 2023, due primarily to decreases in bad debts expense, commissions, facilities and employee-related expenses, partially offset by an increase in advertising expenses as well as $8 million of expenses related to the strategic alternatives review.

Depreciation, amortization and accretion

Depreciation, amortization and accretion expenses decreased in 2023 due primarily to enhancements that extended the useful life of a software platform.

Towers Operations

2024-2023 Commentary

Number of colocations

Number of colocations increased in 2024 due to an increase in new tenant and equipment change executions partially offset by terminations. Colocation terminations decreased in 2024 compared to 2023 in part due to a decrease in legacy Sprint colocation terminations which decreased from 44 to 21 year over year.

Key components of changes in the statement of operations line items were as follows:

2024-2023 Commentary

Total tower revenues

Total tower revenues increased in 2024 due primarily to an increase in intra-company revenues primarily as a result of an increase in the intra-company rate charged by Towers to Wireless and an increase in the number of owned towers.

Upon closing of the transaction to dispose of the wireless operations and select spectrum assets to T-Mobile, UScellular expects an increase in Third-party revenues that will be recognized under the Master License Agreement that will go into effect under the Securities Purchase Agreement. However, at such time Intra-company revenues would cease, resulting in significantly lower Tower revenues in the periods following the close.

42

Index to MD&A

Total operating expenses

Total operating expenses increased in 2024 due to an increase in System operations expenses as a result of increases in cell site ground rent and maintenance expenses.

Upon and following closing of the transaction to dispose of the wireless operations and select spectrum assets to T-Mobile, UScellular expects expenses may be incurred to affect the separation including costs to decommission certain towers and record remaining ground lease obligations on such decommissioned towers. These factors and other uncertainties in how the ongoing tower operations will be supported in the long-term may significantly impact operating expenses recorded in periods following the close.

Capital expenditures

Total capital expenditures decreased in 2024 due primarily to a decrease in the number of owned towers placed into service to support UScellular's wireless network.

2023-2022 Commentary

Total tower revenues

Total tower revenues increased in 2023 due primarily to an increase in third-party revenues primarily as a result of new colocator agreements and rent escalations.

Capital expenditures

Total capital expenditures increased in 2023 due primarily to an increase in the leasehold improvements on owned towers and an increase in perpetual easements and outright land purchases.

Operating Revenues

(Dollars in millions)

Residential revenues consist of:

•Broadband services

•Video services, including IPTV, traditional cable programming and satellite offerings

•Voice services

•Wireless services

Commercial revenues consist of:

•High-speed and dedicated business internet services

•Video services

•Voice services

Wholesale revenues consist of:

•Network access services primarily to interexchange and wireless carriers for carrying data and voice traffic on TDS Telecom's networks

•Federal and state regulatory support, including E-ACAM

Key components of changes in the statement of operations items were as follows:

Total operating revenues

Residential revenues increased for 2024 due primarily to price increases and growth in broadband connections, partially offset by a decline in voice and video connections.

Commercial revenues decreased for 2024 due primarily to declining connections in CLEC markets, partially offset by increases in ad revenue.

Cost of services

Cost of services decreased for 2024 due primarily to lower employee-related expenses, plant and maintenance costs, costs to provide legacy services, and information processing costs, partially offset by higher video programming costs.

Selling, general and administrative

Selling, general and administrative expenses decreased for 2024 due primarily to decreases in employee-related expenses and professional fees, partially offset by higher property taxes and IT infrastructure costs.

Depreciation, amortization and accretion

Depreciation, amortization and accretion increased for 2024 due primarily to increased capital expenditures on new fiber assets and customer premise equipment.

Loss on impairment of intangible assets

During the fourth quarter of 2023, TDS Telecom recorded a $547 million loss on impairment of Goodwill. See Note 8 — Intangible Assets in the Notes to Consolidated Financial Statements for additional information.

Liquidity and Capital Resources

Sources of Liquidity

TDS and its subsidiaries operate capital-intensive businesses. In the past, TDS’ existing cash and investment balances, funds available under its financing agreements, preferred share offerings, and cash flows from operating and certain investing and financing activities, including sales of assets or businesses, provided sufficient liquidity and financial flexibility for TDS to meet its day-to-day operating needs and debt service requirements, to finance the build-out and enhancement of markets, pay dividends and to fund acquisitions. There is no assurance that this will be the case in the future. TDS has incurred negative free cash flow at times in past periods, and this could occur in future periods.

TDS believes that existing cash and investment balances, funds available under its financing agreements, its ability to obtain future external financing, potential dispositions and expected cash flows from operating and investing activities will provide sufficient liquidity for TDS to meet its day-to-day operating needs and debt service requirements. In addition, TDS retains the ability, as described below, to reduce its capital expenditures to lower its funding needs.

TDS may require substantial additional funding for, among other uses, capital expenditures, making additional investments including new technologies, fiber deployments and E-ACAM builds, agreements to purchase goods or services, leases, repurchases of shares, or payment of dividends. It may be necessary from time to time to increase the size of its existing credit facilities, to amend existing or put in place new credit agreements, to obtain other forms of financing, issue equity securities, or to divest assets in order to fund potential expenditures. TDS' liquidity would be adversely affected if it is unable to obtain short or long-term financing on acceptable terms.

TDS will continue to monitor the rapidly changing business and market conditions and is taking and intends to take appropriate actions, as necessary, to meet its liquidity needs. Due to its lack of scale and structural disadvantages, UScellular has higher costs per subscriber than its competitors and is balancing the timing of investments, such as its continued 5G deployment, with liquidity considerations. TDS Telecom has entered into and may continue to enter into agreements to divest of certain non-strategic assets, including in certain cases the associated E-ACAM build-out obligations, as well as slow the pace of and reprioritize its fiber deployment plans and reduce or defer planned capital expenditures as a means to lower its funding needs and meet its obligations. It is possible that TDS Telecom will be required, if it is unable to access capital on acceptable terms, to substantially reduce its plans for fiber deployment, in both the short and long-term, which may result in fewer opportunities to deploy fiber as competitors continue their deployments.

Cash and Cash Equivalents

Cash and cash equivalents include cash and money market investments. The primary objective of TDS’ Cash and cash equivalents investment activities is to preserve principal. TDS does not have direct access to UScellular cash.

Cash and Cash Equivalents

(Dollars in millions)

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. Refer to the Consolidated Cash Flow Analysis for additional information related to changes in Cash and cash equivalents.

Index to MD&A

In addition to Cash and cash equivalents, TDS and UScellular had available undrawn borrowing capacity from the following debt facilities at December 31, 2024. See the Financing section below for further details.

Financing

Revolving Credit Agreements

TDS and UScellular have unsecured revolving credit agreements with maximum borrowing capacities of $400 million and $300 million, respectively. Amounts under the revolving credit agreements may be borrowed, repaid and reborrowed from time to time until maturity in July 2026. During 2024, TDS borrowed $100 million and repaid $200 million under its revolving credit agreement. As of December 31, 2024, TDS' and UScellular’s unused borrowing capacity was $399 million and $300 million, respectively.

As of December 31, 2024, TDS has borrowed the full amounts available under the agreements and the outstanding borrowings were $487 million.

In May 2024, TDS entered into a $375 million unsecured term loan credit agreement. At closing, $300 million was drawn, less original issue discount, and the remaining $75 million may be drawn until November 2025. The maturity date of the agreement is May 2029. As of December 31, 2024, the outstanding borrowings under the agreement were $298 million.

UScellular has unsecured term loan agreements with maximum borrowing capacities of $800 million. The maturity dates for the agreements range from July 2026 to July 2031. During 2024, UScellular repaid $40 million, in addition to required quarterly installments, under its unsecured term loan agreement due July 2026. As of December 31, 2024, UScellular has borrowed the full amount available under the agreements and the outstanding borrowings were $723 million.

Secured Term Loan Agreement

TDS has a $300 million senior secured term loan credit agreement. In February 2025, TDS amended the agreement to extend the maturity date to the earlier of (i) September 2026 and (ii) the scheduled maturity date of TDS' existing revolving credit agreement (which maturity date is currently July 2026). As of December 31, 2024, the outstanding borrowings under the agreement were $300 million, which is the full amount available under the agreement.

This term loan is secured by a perfected security interest in certain assets of TDS, including 26 million common shares in UScellular, TDS' equity interest in certain wholly-owned subsidiaries, and all or substantially all of TDS' personal property that does not constitute equity interests. This term loan is also secured by a perfected security interest in certain assets of certain wholly-owned subsidiaries of TDS that are also guarantors, including without limitation and subject to customary exceptions, equity interests in certain wholly-owned subsidiaries of such subsidiaries and all or substantially all of the personal property of such guarantor subsidiaries that does not consist of equity interests. This agreement includes representations and warranties, covenants, events of default and other terms and conditions that are substantially similar to TDS' existing term loan and revolving credit agreements or otherwise customary for similar secured credit facilities.

Export Credit Financing Agreements

TDS and UScellular each have a $150 million term loan credit facility with Export Development Canada to finance (or refinance) imported equipment, including equipment purchased prior to entering the term loan facility agreement. The maturity date for the TDS agreement is December 2027 and for the UScellular agreement is January 2027. As of December 31, 2024, TDS and UScellular have both borrowed the full amount available under the agreements.

Receivables Securitization Agreement

UScellular, through its subsidiaries, has a receivables securitization agreement that permits securitized borrowings using its equipment installment plan receivables. Amounts under the agreement may be borrowed, repaid and reborrowed from time to time until September 2025. Unless the agreement is amended to extend the maturity date, repayments based on receivable collections commence in October 2025. During 2024, UScellular borrowed $40 million and repaid $188 million under the agreement. As of December 31, 2024, the outstanding borrowings under the agreement were $2 million and classified as Current portion of long-term debt in the Consolidated Balance Sheet, and the unused borrowing capacity was $448 million, subject to sufficient collateral to satisfy the asset borrowing base provisions of the agreement.

Debt Covenants

The TDS and UScellular revolving credit agreements, term loan agreements including the secured term loan, export credit financing agreements and the UScellular receivables securitization agreement require TDS or UScellular, as applicable, to comply with certain affirmative and negative covenants, which include certain financial covenants that may restrict the borrowing capacity available. TDS and UScellular are required to maintain the Consolidated Leverage Ratio as of the end of any fiscal quarter at a level not to exceed the following: 4.25 to 1.00 from January 1, 2023 to March 31, 2024; 4.00 to 1.00 from April 1, 2024 through March 31, 2025; 3.75 to 1.00 from April 1, 2025 and thereafter. TDS and UScellular 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 UScellular believe that they were in compliance as of December 31, 2024 with all such financial covenants.

The term loan agreement entered into in May 2024 requires TDS to comply with certain affirmative and negative covenants, which includes a financial covenant that may restrict the borrowing capacity available. TDS is required to maintain the Consolidated Leverage Ratio as of the end of any fiscal quarter at a level not to exceed the following: 4.50 to 1.00 from April 1, 2024 through March 31, 2025; 4.25 to 1.00 from April 1, 2025 and thereafter. TDS believes that it was in compliance as of December 31, 2024 with such financial covenant.

TDS believes that it and/or its subsidiaries were in compliance as of December 31, 2024, with all covenants and other requirements set forth in the TDS and UScellular long-term debt indentures. TDS and UScellular have not failed to make nor do they expect to fail to make any scheduled payment of principal or interest under such indentures.

Other Long-Term Financing

TDS and UScellular each have an effective shelf registration statement on Form S-3 to issue senior or subordinated debt securities, preferred shares and depositary shares. The proceeds from any such issuances may be used for general corporate purposes, including the possible reduction of other short-term or long-term debt; spectrum purchases; capital expenditures; acquisition, construction and development programs; working capital; additional investments in subsidiaries; or the repurchase of shares. The ability of TDS or UScellular to complete an offering pursuant to such shelf registration statements is subject to market conditions and other factors at the time.

TDS and UScellular, at their discretion, may from time to time seek to retire or purchase their outstanding debt through cash purchases and/or exchanges for other securities, in open market purchases, privately negotiated transactions, tender offers, exchange offers or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Refer to Market Risk — Long-Term Debt for additional information regarding required principal payments and the weighted average interest rates related to TDS’ Long-term debt.

See Note 13 — Debt in the Notes to Consolidated Financial Statements for additional information related to the financing agreements.

Credit Ratings

In certain circumstances, TDS’ and UScellular’s interest cost on their various agreements may be subject to increase if their current credit ratings from nationally recognized credit rating agencies are lowered, and may be subject to decrease if the ratings are raised. The agreements do not cease to be available nor do the maturity dates accelerate solely as a result of a downgrade in TDS’ or UScellular’s credit rating. However, downgrades in TDS’ or UScellular’s credit rating could adversely affect their ability to renew the agreements, obtain consents, waivers, or amendments, or obtain access to other credit agreements in the future.

TDS and UScellular are rated as sub-investment grade issuers. The TDS and UScellular issuer credit ratings as of December 31, 2024, and the dates such ratings were issued were as follows:

The TDS and UScellular credit ratings may be impacted in the future based on the outcomes of the T-Mobile, Verizon and AT&T transactions and the remaining UScellular business, among other factors.

Capital Requirements

The discussion below is intended to highlight some of the significant cash outlays expected during 2025 and beyond and to highlight the spending incurred in current and prior years for these items. This discussion does not include cash required to fund normal operations, and is not a comprehensive list of capital requirements. Significant cash requirements that are not routine or in the normal course of business could arise from time to time.

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 2025 and future years with the continued deployment of 5G technology for UScellular, and the continued deployment of fiber for TDS Telecom.

Capital expenditures (i.e., additions to property, plant and equipment and system development expenditures; excludes wireless spectrum license additions), which include the effects of accruals and capitalized interest, in 2024, 2023 and 2022 were as follows:

Capital Expenditures

(Dollars in millions)

UScellular’s capital expenditures were $577 million, $611 million and $717 million in 2024, 2023 and 2022, respectively. In 2024, UScellular's capital expenditures were used for the following purposes:

•Continue to deploy 5G using mid-band spectrum to provide additional speed and capacity to accommodate increased data usage by current customers; and

•Invest in information technology to support existing and new services and products.

TDS Telecom’s capital expenditures were $324 million, $577 million and $556 million in 2024, 2023 and 2022, respectively. In 2024, these capital expenditures were used for the following purposes:

•Continue to expand fiber deployment primarily in expansion markets;

•Support broadband growth and success-based spending; and

•Maintain and enhance existing infrastructure including build-out requirements of state broadband and E-ACAM programs.

TDS Telecom's capital expenditures for 2025 are expected to be between $375 million and $425 million. These expenditures are expected to be used for similar purposes as those listed above.

TDS intends to finance its capital expenditures for 2025 using primarily Cash flows from operating activities, existing cash balances and additional debt financing from its existing agreements and/or other forms of available financing.

Divestitures

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

See Note 7 — Divestitures in the Notes to Consolidated Financial Statements for additional information related to divestitures.

53

Index to MD&A

Other Obligations

TDS will require capital for future spending on existing contractual obligations, including long-term debt obligations; preferred stock dividend obligations; lease commitments; commitments for device purchases, network facilities and transport services; E-ACAM obligations; agreements for software licensing; long-term marketing programs; and other agreements to purchase goods or services. TDS has taken and expects to continue to take steps to reduce and defer capital expenditures to lower its funding needs. Refer to Liquidity and Capital Resources within this MD&A for additional information.

Variable Interest Entities

TDS consolidates certain “variable interest entities” as defined under GAAP. See Note 16 — Variable Interest Entities in the Notes to Consolidated Financial Statements for additional information related to these variable interest entities. TDS may elect to make additional capital contributions and/or advances to these variable interest entities in future periods to fund their operations.

Common Share Repurchase Programs

TDS had no share repurchases during 2024. As of December 31, 2024, the maximum dollar value of TDS Common Shares that may yet be purchased under TDS' program was $132 million.

During 2024, UScellular repurchased 939,999 Common Shares for $55 million at an average cost per share of $58.06. At December 31, 2024, the total cumulative amount of UScellular Common Shares authorized to be repurchased is 986,942.

Depending on its future financial performance, construction, development and acquisition programs, and available sources of financing, TDS and UScellular may not have sufficient liquidity or capital resources to make share repurchases. Therefore, there is no assurance that TDS and UScellular will make any share repurchases in the future.

For additional information related to the current TDS and UScellular repurchase authorizations, see Note 18 — Shareholders’ Equity in the Notes to Consolidated Financial Statements.

Dividends

TDS paid quarterly dividends per outstanding share of $0.19 in the first quarter of 2024 and $0.04 in each of the second, third and fourth quarters of 2024. TDS paid quarterly dividends per outstanding share of $0.185 in 2023 and $0.180 in 2022. It is uncertain at this time how the outcome of the ongoing strategic alternatives review process for UScellular, TDS' available opportunities to reinvest in its businesses, or TDS' ongoing liquidity needs, may impact the decisions of the TDS Board of Directors regarding the declaration of future dividends.

TDS paid quarterly dividends per outstanding Series UU depositary share (each representing 1/1,000th of a Preferred Share) of $0.414 in 2024, 2023 and 2022.

TDS paid quarterly dividends per outstanding Series VV depositary share (each representing 1/1,000th of a Preferred Share) of $0.375 in 2024, 2023 and 2022.

Consolidated Cash Flow Analysis

TDS operates a capital-intensive business. TDS makes substantial investments to acquire wireless spectrum licenses and to construct and upgrade communications networks and facilities with a goal of creating long-term value for shareholders. In recent years, rapid changes in technology and new opportunities have required substantial investments in potentially revenue‑enhancing and cost-saving upgrades to TDS’ networks. Revenues from certain of these investments are long-term and in some cases are uncertain. To meet its cash-flow needs, TDS may need to delay or reduce certain investments, dividend payments or sell assets. Refer to Liquidity and Capital Resources within this MD&A and Note 7 — Divestitures in the Notes to Consolidated Financial Statements for additional information. Cash flows may fluctuate from quarter to quarter and year to year due to seasonality, timing and other factors. The following discussion summarizes TDS’ cash flow activities in 2024 and 2023. For a discussion of 2022, refer to Management's Discussion and Analysis of Financial Condition and Results of Operations in TDS' Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 16, 2024.

2024 Commentary

TDS’ Cash, cash equivalents and restricted cash increased $114 million. Net cash provided by operating activities was $1,145 million due to net loss of $26 million adjusted for non-cash items of $1,070 million and distributions received from unconsolidated entities of $169 million, including $75 million in distributions from the LA Partnership. This was partially offset by changes in working capital items which decreased net cash by $68 million. The working capital changes were primarily driven by an increase in receivable balances and the timing of vendor payments, partially offset by reduced inventory balances.

Distributions from certain equity method investments operated by Verizon are expected to include incremental discrete amounts in 2025 related to proceeds received by Verizon in the tower transaction with Vertical Bridge that closed in December 2024. The process of administering these distributions is in progress and it is uncertain whether such incremental discrete amounts will result in an increase in total distributions from these partnerships in 2025 relative to 2024 given that the final amount of the incremental distributions is not known, and total distributions are dependent upon the operations of the underlying operating companies, and the general partners’ decisions on the amount and timing of any distributions, among other factors.

Cash flows used for investing activities were $754 million, due primarily to payments for property, plant and equipment of $884 million and payments for wireless spectrum licenses of $20 million, partially offset by cash received from divestitures of $147 million.

Cash flows used for financing activities were $277 million, due primarily to $200 million in repayments on the TDS revolving credit agreement, $188 million in repayments on the UScellular receivables securitization agreement, $67 million in repayments on the TDS and UScellular term loan agreements, payment of $104 million in dividends, cash paid for software licenses of $67 million and the repurchase of $54 million of UScellular Common Shares. These were partially offset by $300 million borrowed under the TDS term loan agreements, $100 million borrowed under the TDS revolving credit agreement and $40 million borrowed under the receivables securitization agreement.

2023 Commentary

TDS’ Cash, cash equivalents and restricted cash decreased $129 million. Net cash provided by operating activities was $1,142 million due to a net loss of $487 million adjusted for non-cash items of $1,496 million and distributions received from unconsolidated entities of $150 million, including $69 million in distributions from the LA Partnership. This was partially offset by changes in working capital items which decreased net cash by $17 million. The working capital changes were primarily driven by the timing of vendor payments and an increase in receivables, partially offset by reduced inventory balances and a federal income tax refund of $57 million received during the second quarter of 2023.

Cash flows used for investing activities were $1,327 million, which included payments for property, plant and equipment of $1,211 million and payments for wireless spectrum licenses of $130 million.

Cash flows provided by financing activities were $56 million, due primarily to $365 million borrowed under the TDS revolving credit agreement, $315 million borrowed under the UScellular receivables securitization agreement, $300 million borrowed under the TDS secured term loan agreement, and $100 million borrowed under the TDS export credit agreement. These were partially offset by $440 million in repayments on the UScellular receivables securitization agreement, $265 million in repayments on the TDS revolving credit agreement, a $60 million repayment on the UScellular EIP receivables repurchase agreement, payment of $153 million in dividends and cash paid for software license agreements of $66 million.

Application of Critical Accounting Policies and Estimates

TDS prepares its consolidated financial statements in accordance with GAAP. TDS’ significant accounting policies are discussed in detail in Note 1 — Summary of Significant Accounting Policies, Note 2 — Revenue Recognition and Note 11 — Leases in the Notes to Consolidated Financial Statements.

Management believes the application of the following critical accounting policies and the estimates required by such application reflect its most significant judgments and estimates used in the preparation of TDS’ consolidated financial statements.

Wireless Spectrum License Impairment – UScellular

Wireless spectrum licenses represent a significant component of UScellular’s consolidated assets. Wireless spectrum licenses, including those with FCC build-out requirements that have not yet been satisfied, are considered to be indefinite-lived assets, and therefore, are not amortized but are tested for impairment annually or more frequently if there are events or circumstances that cause UScellular to believe that their carrying values exceed their fair values. Wireless spectrum licenses are tested for impairment at the level of reporting referred to as a unit of accounting.

As a result of executing the Securities Purchase Agreement with T-Mobile during the second quarter of 2024, UScellular bifurcated its historical single unit of accounting into two units of accounting – wireless spectrum licenses to be sold under the Securities Purchase Agreement and wireless spectrum licenses to be retained. During the third quarter of 2024, UScellular’s efforts to monetize its spectrum assets not subject to the Securities Purchase Agreement provided new evidence that the highest and best use of the retained spectrum to current buyers would be in separate tranches. As a result, UScellular further divided its wireless spectrum licenses units of accounting from one retained unit into eleven units, resulting in twelve total units of accounting. UScellular concluded that there were events and circumstances in the third quarter of 2024 that caused UScellular to believe the carrying values of five of the units of accounting may exceed their respective fair values (i.e. triggering event), and accordingly a quantitative impairment assessment was performed for those units. There was no triggering event for the other units of accounting.

A market approach was used for purposes of the quantitative impairment assessment to value the wireless spectrum licenses for the five units tested, using a range of values established largely through industry benchmarks, FCC auction data, and precedent transactions. The midpoint of the range was established as the estimate of fair value for each unit of accounting. Based on this valuation, the fair value of the wireless spectrum licenses exceeded their respective carrying values by amounts ranging from 9% to 80% for three of the units of accounting. For two of the units of accounting, the fair value of the wireless spectrum licenses was less than the respective carrying value, and a $136 million impairment was recorded to Loss on impairment of licenses in the Consolidated Statement of Operations within UScellular’s Wireless segment during the third quarter of 2024. Substantially all of the impairment loss related to the retained high-band spectrum unit of accounting which includes the 28 GHz, 37 GHz and 39 GHz frequency bands, the carrying value of which was $161 million after the impairment loss. The impairment loss is driven by the change in the units of accounting described above combined with lower fair value primarily attributed to high-band spectrum as a result of industry-wide challenges encountered related to the operationalization of this spectrum.

For purposes of its annual impairment test as of November 1, 2024, UScellular performed a qualitative test for all twelve of its units of accounting. The test considered several factors, including the results of the quantitative impairment assessment performed in the third quarter of 2024 as well as purchase prices of executed agreements to sell certain wireless spectrum licenses and other market factors. Based on these assessments, UScellular concluded that it was more likely than not that the fair value of each unit of accounting exceeded its respective carrying value. Therefore, no quantitative impairment evaluation was completed.

For purposes of its 2023 impairment test, UScellular had one unit of accounting and used a quantitative market approach to value the wireless spectrum license portfolio. The wireless spectrum licenses were pooled by band, and a range of values was established using industry benchmarks, FCC auction data, and precedent transactions. The midpoint of the range was established as the point estimate for the value of each band, and the sum of the band values was used as the point estimate value of UScellular's wireless spectrum license unit of accounting. Based on this valuation, the fair value of the wireless spectrum licenses exceeded the respective carrying value by 17% and there was no impairment of wireless spectrum licenses.

Income Taxes

The amounts of income tax assets and liabilities, the related income tax provision and the amount of unrecognized tax benefits are critical accounting estimates because such amounts are significant to TDS’ financial condition and results of operations.

The preparation of the consolidated financial statements requires TDS to calculate a provision for income taxes. This process involves estimating the actual current income tax liability together with assessing temporary differences resulting from the different treatment of items for tax purposes. These temporary differences result in deferred income tax assets and liabilities which are included on a net basis in TDS’ Consolidated Balance Sheet. TDS must then assess the likelihood that deferred income tax assets will be realized based on future taxable income and, to the extent management believes that realization is not likely, establish a valuation allowance. Management’s judgment is required in determining the provision for income taxes, deferred income tax assets and liabilities and any valuation allowance that is established for deferred income tax assets.

57

Index to MD&A

TDS recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on management’s judgment as to the possible outcome that has a greater than 50% cumulative likelihood of being realized upon ultimate resolution.

See Note 5 — Income Taxes in the Notes to Consolidated Financial Statements for additional information.

Regulatory Matters

5G Fund

On October 27, 2020, the FCC adopted rules creating the 5G Fund for Rural America, which will distribute up to $9 billion over ten years to bring 5G wireless broadband connectivity to rural America. The 5G Fund will be implemented through a two-phase competitive process, using multiround auctions to award support. The winning bidders will be required to meet certain minimum speed requirements and interim and final deployment milestones. The order provides that the 5G Fund be in lieu of the previously proposed fund (the Phase II Connect America Mobility Fund) for the development of 4G LTE. The order also provides that over time a growing percentage of the legacy support a carrier receives must be used for 5G deployment. On September 22, 2023, the FCC adopted a Further Notice of Proposed Rulemaking (FNPRM) to continue implementation of the 5G Fund. The FCC sought comment on, among other things, the definition of areas eligible for 5G Fund support, adjustment factors and metrics used to identify winning bids, and the potential inclusion of cybersecurity and supply chain management requirements for those receiving 5G Fund support. On August 29, 2024, the FCC adopted new rules to move forward with targeted investments in the deployment of advanced, 5G mobile wireless broadband services in rural communities through the 5G Fund auction process. The start date of the auction was not announced.

UScellular cannot predict at this time when the 5G Fund auction will occur, when the phase down period for its existing legacy support from the Federal USF will commence, or whether the 5G Fund auction will provide opportunities to UScellular to offset any loss in existing support.

Spectrum Auctions

On February 24, 2021, the FCC announced by way of Public Notice that UScellular was the provisional winning bidder of 254 wireless spectrum licenses in the 3.7-3.98 GHz bands for $1,283 million in Auction 107. UScellular paid $30 million of this amount in 2020 and the remainder in March 2021 and the wireless spectrum licenses were granted by the FCC in July 2021. Additionally, UScellular was obligated to pay relocation costs and accelerated relocation incentive payments of $8 million, $122 million, $8 million and $36 million in the years ended December 31, 2024, 2023, 2022 and 2021, respectively. Such additional costs were estimated, accrued and capitalized at the time the licenses were granted and have been adjusted as such costs were finalized. UScellular received full access to the spectrum in the third quarter of 2023.

FCC Enhanced Alternative Connect America Cost Model (E-ACAM)

On July 24, 2023, the FCC released an order adopting the E-ACAM program for the purpose of supporting widespread deployment of 100/20 Mbps service speeds in eligible rural areas. The program is offered and extended to carriers currently receiving ACAM or legacy rate-of-return support.

On September 28, 2023, TDS Telecom notified the FCC of its decision to accept 24 of the 25 state offers received for E-ACAM support. The enhanced program will help enable TDS Telecom to deploy high-speed internet to approximately 300,000 locations, including those eligible for E-ACAM support and those passed along the route. Starting in 2024, TDS Telecom expects to receive support of approximately $90 million per year for 15 years in exchange for meeting the 100/20 Mbps service requirement. The support replaces the prior ACAM program support received for the 24 states where TDS Telecom has wireline operations. On October 30, 2023, the Wireline Competition Bureau issued a public notice authorizing the Universal Service Administrative Company to disburse the appropriate amounts. TDS Telecom will incur capital expenditures over the next several years to meet its obligations to serve the required locations with 100/20 Mbps service.

Announced Transaction and Strategic Alternatives Review Risk Factors

▪TDS and UScellular entered into a Securities Purchase Agreement dated as of May 24, 2024 with T-Mobile and USCC Wireless Holdings, LLC, pursuant to which, among other things, UScellular has agreed to sell its wireless operations and select spectrum assets to T-Mobile. In addition, UScellular, and certain subsidiaries of UScellular, entered into the Verizon Purchase Agreement on October 17, 2024, and the AT&T Purchase Agreement on November 6, 2024 to sell certain wireless spectrum licenses. There is no guarantee that the transactions contemplated by the Securities Purchase Agreement, the Verizon Purchase Agreement, or the AT&T Purchase Agreement will be able to be consummated or that UScellular will be able to find buyers at mutually agreeable prices for its spectrum assets not subject to the Securities Purchase Agreement, the Verizon Purchase Agreement, or the AT&T Purchase Agreement. Costs and uncertainties related to the transactions could have adverse effects on TDS’ financial condition or results of operations.

▪If the T-Mobile, Verizon and AT&T transactions are not consummated, substantial changes will be required to the manner in which UScellular’s wireless business is conducted, and we expect there will be a material adverse effect on TDS' financial condition and results of operations.

▪If the T-Mobile, Verizon and AT&T transactions are consummated, substantial costs will be triggered and substantial changes will be required to the manner in which UScellular’s remaining business is conducted, which could have a material adverse effect on TDS' financial condition and results of operations.

Operational Risk Factors

▪A delay or failure by TDS to complete significant network construction and systems implementation activities as part of its plans to improve the quality, coverage, capabilities and capacity of its network, support and other systems and infrastructure as well as renew wireless spectrum licenses, could adversely affect its operations.

▪Intense competition involving products, services, pricing, promotions and network speed and technologies could adversely affect TDS’ revenues or increase its costs to compete.

▪TDS’ lack of scale and structural disadvantages, particularly in the wireless business, relative to larger competitors that may have greater financial and other resources than TDS has caused and could continue to cause TDS to be unable to compete successfully, which has adversely affected and could continue to adversely affect its business, financial condition or results of operations.

▪Changes in roaming practices or other factors could cause TDS’ roaming revenues to decline from current levels, roaming expenses to increase from current levels and/or impact TDS’ ability to service its customers in geographic areas where TDS does not have its own network, which could have an adverse effect on TDS’ business, financial condition or results of operations.

▪An inability to attract people of outstanding talent throughout all levels of the organization, to develop their potential through education and assignments, and to retain them by keeping them engaged, challenged and properly rewarded could have an adverse effect on TDS' business, financial condition or results of operations.

▪Changes in various business factors, including changes in demand, consumer preferences and perceptions, price competition, cost increases, churn from customer switching activity and other factors, could have an adverse effect on TDS’ business, financial condition or results of operations.

▪A failure by TDS to obtain access to adequate radio spectrum to meet current or anticipated future needs and/or to accurately predict future needs for radio spectrum could have an adverse effect on TDS’ business, financial condition or results of operations.

▪Advances or changes in technology could render certain technologies used by TDS obsolete, could put TDS at a competitive disadvantage, could reduce TDS’ revenues or could increase its costs of doing business.

▪Complexities associated with deploying new technologies present substantial risk and TDS’ investments in unproven technologies may not produce the benefits that TDS expects.

▪Costs, integration problems or other factors associated with acquisitions, divestitures or exchanges of properties or wireless spectrum licenses and/or expansion of TDS’ businesses could have an adverse effect on TDS’ business, financial condition or results of operations.

▪Difficulties involving third parties with which TDS does business, including changes in TDS’ relationships with or financial or operational difficulties, including supply chain disruptions, of key suppliers or independent agents and third-party national retailers who market TDS’ services, could adversely affect TDS’ business, financial condition or results of operations.

▪A failure by TDS to maintain flexible and capable telecommunication networks or information technologies, or a material disruption thereof, could have an adverse effect on TDS’ business, financial condition or results of operations.

Financial Risk Factors

▪Uncertainty in TDS’ or UScellular's future cash flow and liquidity or the inability to access capital, deterioration in the capital markets, changes in interest rates, other changes in TDS’ or UScellular's performance or market conditions, changes in TDS’ or UScellular's credit ratings or other factors could limit or restrict the availability of financing on terms and prices acceptable to TDS, which has required and is expected in the future to require TDS to reduce or delay its construction, development or acquisition programs, divest assets or businesses, and/or reduce or cease share repurchases and/or the payment of common shareholder dividends.

▪TDS has a significant amount of indebtedness which could adversely affect its financial performance and in turn adversely affect its ability to make payments on its indebtedness, comply with terms of debt covenants and incur additional debt.

▪TDS has entered into a Senior Secured Credit Agreement that imposes certain restrictions on its business and operations that may affect its ability to operate its business and make payments on its indebtedness.

▪TDS’ assets and revenue are concentrated primarily in the U.S. telecommunications industry. Consequently, its operating results may fluctuate based on factors related primarily to conditions in this industry.

▪TDS has significant investments in entities that it does not control. Losses in the value of such investments could have an adverse effect on TDS’ financial condition or results of operations.

Regulatory, Legal and Governance Risk Factors

▪Failure by TDS to timely or fully comply with any existing applicable legislative and/or regulatory requirements or changes thereto could adversely affect TDS’ business, financial condition or results of operations.

▪TDS receives significant regulatory support, and is also subject to numerous surcharges and fees from federal, state and local governments – the applicability and the amount of the support and fees are subject to uncertainty, including the ability to pass through certain fees to customers, and this uncertainty could have an adverse effect on TDS’ business, financial condition or results of operations.

▪Settlements, judgments, restraints on its current or future manner of doing business and/or costs resulting from pending and future legal and policy proceedings could have an adverse effect on TDS’ business, financial condition or results of operations.

▪The possible development of adverse precedent in litigation or conclusions in professional or environmental studies to the effect that potentially harmful emissions from devices or network equipment, including but not limited to radio frequencies emitted by wireless signals or due to contamination from network cabling, may cause harmful health or environmental consequences, including cancer, tumors or otherwise harmful impacts, or may interfere with various electronic medical devices or frequencies used by other industries, could have an adverse effect on TDS’ wireless and/or wireline business, financial condition or results of operations.

▪Claims of infringement of intellectual property and proprietary rights of others, primarily involving patent infringement claims, could prevent TDS from using necessary technology to provide products or services or subject TDS to expensive intellectual property litigation or monetary penalties, which could have an adverse effect on TDS’ business, financial condition or results of operations.

▪Certain matters, such as control by the TDS Voting Trust and provisions in the TDS Restated Certificate of Incorporation, may serve to discourage or make more difficult a change in control of TDS or have other consequences.

▪TDS has experienced, and in the future expects to experience, cyber-attacks or other breaches of network or information technology security of varying degrees on a regular basis, which could have an adverse effect on TDS' business, financial condition or results of operations.

▪Disruption in credit or other financial markets, a deterioration of U.S. or global economic conditions or other events could, among other things, impede TDS’ access to or increase the cost of financing its operating and investment activities and/or result in reduced revenues and lower operating income and cash flows, which would have an adverse effect on TDS’ business, financial condition or results of operations.

▪The impact of public health emergencies on TDS' business is uncertain, but depending on duration and severity could have a material adverse effect on TDS' business, financial condition or results of operations.

Market Risk

Long-Term Debt

As of December 31, 2024, approximately 50% of TDS' long-term debt was in fixed-rate senior notes and approximately 50% in variable-rate debt. Fluctuations in market interest rates can lead to volatility in the fair value of fixed-rate notes and interest expense on variable-rate debt.

The following table presents the scheduled principal payments on long-term debt, lease obligations and the related weighted average interest rates by maturity dates at December 31, 2024:

1The total long-term debt obligation differs from Long-term debt in the Consolidated Balance Sheet due to unamortized debt issuance costs on all non-revolving debt instruments, and unamortized discounts related to UScellular's 6.7% Senior Notes. The 2025 amount includes repayment of $2 million of outstanding borrowings under the receivables securitization agreement. If the maturity date of the facility is not extended, principal repayments begin in October 2025. If the T-Mobile transaction is consummated, TDS expects to repay outstanding borrowings under certain long-term debt obligations. See Note 13 — Debt in the Notes to Consolidated Financial Statements for additional information.

2Represents the weighted average stated interest rates at December 31, 2024, for debt maturing in the respective periods.

Fair Value of Long-Term Debt

At December 31, 2024 and 2023, the estimated fair value of long-term debt obligations, excluding lease obligations, the current portion of such long-term debt and debt financing costs, was $4,015 million and $3,651 million, respectively, and the book value was $4,119 million and $4,139 million, respectively. See Note 3 — Fair Value Measurements in the Notes to Consolidated Financial Statements for additional information.

Supplemental Information Relating to Non-GAAP Financial Measures

TDS sometimes uses information derived from consolidated financial information but not presented in its financial statements prepared in accordance with GAAP to evaluate the performance of its business. Certain of these measures are considered “non-GAAP financial measures” under U.S. Securities and Exchange Commission Rules. Specifically, TDS has referred to the following measures in this Form 10-K Report:

▪EBITDA

▪Adjusted EBITDA

▪Adjusted OIBDA

▪Free cash flow

▪Intangible assets impairment, net of tax

Following are explanations of each of these measures:

EBITDA, Adjusted EBITDA and Adjusted OIBDA

EBITDA, Adjusted EBITDA and Adjusted OIBDA are defined as Net income (loss) adjusted for the items set forth in the reconciliation below. EBITDA, Adjusted EBITDA and Adjusted OIBDA are not measures of financial performance under GAAP and should not be considered as alternatives to Net income (loss) or Cash flows from operating activities, as indicators of cash flows or as measures of liquidity. TDS does not intend to imply that any such items set forth in the reconciliation below are non-recurring, infrequent or unusual; such items may occur in the future.

Adjusted EBITDA is a segment measure reported to the chief operating decision maker for purposes of assessing the segments' performance. See Note 20 — Business Segment Information in the Notes to Consolidated Financial Statements for additional information.

Management uses Adjusted EBITDA and Adjusted OIBDA as measurements of profitability, and therefore reconciliations to applicable GAAP income measures are deemed appropriate. Management believes Adjusted EBITDA and Adjusted OIBDA are useful measures of TDS’ operating results before significant recurring non-cash charges, nonrecurring expenses, gains and losses, and other items as presented below as they provide additional relevant and useful information to investors and other users of TDS’ financial data in evaluating the effectiveness of its operations and underlying business trends in a manner that is consistent with management’s evaluation of business performance. Adjusted EBITDA shows adjusted earnings before interest, taxes, depreciation, amortization and accretion, gains and losses, and expenses related to the strategic alternatives review of UScellular, while Adjusted OIBDA reduces this measure further to exclude Equity in earnings of unconsolidated entities and Interest and dividend income in order to more effectively show the performance of operating activities excluding investment activities. The following tables reconcile EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measures, Net income (loss) and/or Operating income (loss). Income and expense items below Operating income (loss) are not provided at the individual segment level for Wireless and Towers; therefore, the reconciliations begin with EBITDA and the most directly comparable GAAP measure is Operating income (loss) rather than Net income (loss) at the segment level.

Free Cash Flow

The following table presents Free cash flow, which is defined as Cash flows from operating activities less Cash paid for additions to property, plant and equipment and Cash paid for software license agreements. Free cash flow is a non-GAAP financial measure which TDS believes may be useful to investors and other users of its financial information in evaluating liquidity, specifically, the amount of net cash generated by business operations after deducting Cash paid for additions to property, plant and equipment and Cash paid for software license agreements.

Intangible assets impairment, net of tax

The following non-GAAP financial measure isolates the total effects on net income of the Loss on impairment of intangible assets at TDS Telecom and UScellular, including tax impacts. TDS believes this measure may be useful to investors and other users of its financial information to assist in comparing financial results with periods that were not impacted by impairment charges.
