AT&T INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1. PREPARATION OF INTERIM FINANCIAL STATEMENTS

Basis of Presentation Throughout this document, AT&T Inc. is referred to as “we,” “AT&T” or the “Company.” The consolidated financial statements include the accounts of the Company and subsidiaries and affiliates which we control. AT&T is a holding company whose subsidiaries and affiliates operate worldwide in the telecommunications and technology industries. You should read this document in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2023. The results for the interim periods are not necessarily indicative of those for the full year. These consolidated financial statements include all adjustments that are necessary to present fairly the results for the presented interim periods, consisting of normal recurring accruals and other items.

All significant intercompany transactions are eliminated in the consolidation process. Investments in subsidiaries and partnerships which we do not control but have significant influence are accounted for under the equity method. Earnings from certain investments accounted for using the equity method are included in our results on a one quarter lag. We also record our proportionate share of our equity method investees’ other comprehensive income (OCI) items, including translation adjustments.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions, including estimates of fair value, probable losses and expenses, that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

NOTE 2. EARNINGS PER SHARE

A reconciliation of the numerators and denominators of basic and diluted earnings per share is shown in the table below:

On April 5, 2023, we repurchased all our Series A Cumulative Perpetual Preferred Membership Interests in AT&T Mobility II LLC (Mobility preferred interests). For periods prior to repurchase, under Accounting Standards Update (ASU) No. 2020-06, “Debt—Debt With Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (ASU 2020-06), the ability to settle the Mobility preferred interests in stock was reflected in our diluted earnings per share calculation.

NOTE 3. OTHER COMPREHENSIVE INCOME

Changes in the balances of each component included in accumulated OCI are presented below. All amounts are net of tax.

NOTE 4. SEGMENT INFORMATION

Our segments are comprised of strategic business units or other operations that offer products and services to different customer segments over various technology platforms and/or in different geographies that are managed accordingly. We havetwo reportable segments: Communications and Latin America.

We also evaluate segment and business unit performance based on EBITDA and/or EBITDA margin, which is defined as operating income excluding depreciation and amortization. EBITDA is used as part of our management reporting and we believe EBITDA to be a relevant and useful measurement to our investors as it measures the cash generation potential of our business units. EBITDA does not give effect to depreciation and amortization expenses incurred in operating income nor is it burdened by cash used for debt service requirements and thus does not reflect available funds for distributions, reinvestment or other discretionary uses. EBITDA margin is EBITDA divided by total revenue.

The Communications segment provides wireless and wireline telecom and broadband services to consumers located in the U.S. and businesses globally. Our business strategies reflect integrated product offerings that cut across product lines and utilize shared assets. This segment contains the following business units:

•Mobility provides nationwide wireless service and equipment.

•Business Wireline provides advanced ethernet-based fiber services, IP Voice and managed professional services, as well as traditional voice and data services and related equipment to business customers. In the first quarter of 2024, we began offering our fixed wireless access product that provides internet services delivered over our 5G wireless network where available.

•Consumer Wireline provides broadband services, including fiber connections that provide multi-gig services to residential customers in select locations and our fixed wireless access product that provides home internet services delivered over our 5G wireless network where available. Consumer Wireline also provides legacy telephony voice communication services.

The Latin America segment provides wireless services and equipment in Mexico.

Corporate and Other reconciles our segment results to consolidated operating income and income before income taxes.

Corporate includes:

•DTV-related retained costs, which are costs previously allocated to the Video business that were retained after the transaction, net of reimbursements from DIRECTV Entertainment Holdings, LLC (DIRECTV) under transition service agreements.

•Parent administration support, which includes costs borne by AT&T where the business units do not influence decision making.

•Securitization fees associated with our sales of receivables (see Note 8).

•Value portfolio, which are businesses no longer integral to our operations or which we no longer actively market.

Other items consist of:

•Certain significant items, which includes items associated with the merger and integration of acquired or divested businesses, including amortization of intangible assets, employee separation charges associated with voluntary and/or strategic offers, asset impairments and abandonments and restructuring, and other items for which the segments are not being evaluated.

“Interest expense” and “Other income (expense) – net” are managed only on a total company basis and are, accordingly, reflected only in consolidated results.

The following table is a reconciliation of Segment Operating Income to “Income Before Income Taxes” reported in our consolidated statements of income:

NOTE 5. REVENUE RECOGNITION

Revenue Categories

The following tables set forth reported revenue by category and by business unit:

Deferred Customer Contract Acquisition and Fulfillment Costs

Costs to acquire and fulfill customer contracts, including commissions on service activations for our Mobility, Business Wireline and Consumer Wireline services, are deferred and amortized over the contract period or expected customer relationship life, which typically ranges from three years tofive years.

The following table presents the deferred customer contract acquisition and fulfillment costs included on our consolidated balance sheets:

The following table presents deferred customer contract acquisition and fulfillment cost amortization, which are primarily included in “Selling, general and administrative” and “Other cost of revenues,” respectively, for the six months ended:

Contract Assets and Liabilities

A contract asset is recorded when revenue is recognized in advance of our right to bill and receive consideration. The contract asset will decrease as services are provided and billed. For example, when installment sales include promotional discounts (e.g., trade-in device credits) the difference between revenue recognized and consideration received is recorded as a contract asset to be amortized over the contract term.

Our contract assets primarily relate to our wireless businesses. Promotional equipment sales where we offer handset credits, which are allocated between equipment and service in proportion to their standalone selling prices, when customers commit to a specified service period result in additional contract assets recognized. These contract assets will amortize over the service contract period, resulting in lower future service revenue.

When consideration is received in advance of the delivery of goods or services, a contract liability is recorded. Reductions in the contract liability will be recorded as we satisfy the performance obligations.

The following table presents contract assets and liabilities on our consolidated balance sheets:

Our beginning of period contract liability recorded as customer contract revenue during 2024 was $3,142.

Remaining Performance Obligations

Remaining performance obligations represent services we are required to provide to customers under bundled or discounted arrangements, which are satisfied as services are provided over the contract term. In determining the transaction price allocated, we do not include non-recurring charges and estimates for usage, nor do we consider arrangements with an original expected duration of less than one year, which are primarily prepaid wireless and residential internet agreements.

Remaining performance obligations associated with business contracts reflect recurring charges billed, adjusted to reflect estimates for sales incentives and revenue adjustments. Performance obligations associated with wireless contracts are estimated using a portfolio approach in which we review all relevant promotional activities, calculating the remaining performance obligation using the average service component for the portfolio and the average device price. As of June 30, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations was $38,744, of which we expect to recognize approximately 72% by the end of 2025, with the balance recognized thereafter.

NOTE 6. PENSION AND POSTRETIREMENT BENEFITS

Many of our employees are covered by one of our noncontributory pension plans. We also provide certain medical, dental, life insurance and death benefits to certain retired employees under various plans and accrue actuarially determined postretirement benefit costs. Our objective in funding these plans, in combination with the standards of the Employee Retirement Income Security Act of 1974, as amended (ERISA), is to accumulate assets sufficient to provide benefits described in the plans to employees upon their retirement. We do not have significant funding requirements in 2024.

We recognize actuarial gains and losses on pension and postretirement plan assets in our consolidated results as a component of “Other income (expense) – net” at our annual measurement date of December 31, unless earlier remeasurements are required.

The following table details qualified pension and postretirement benefit costs included in the accompanying consolidated statements of income. The service cost component of net periodic pension (credit) cost is recorded in operating expenses in the consolidated statements of income while the remaining components are recorded in “Other income (expense) – net.”

We also provide senior- and middle-management employees with nonqualified, unfunded supplemental retirement and savings plans. Net supplemental pension benefits costs not included in the table above were $16 and $18 in the second quarter and $33 and $37 for the first six months of 2024 and 2023, respectively.

NOTE 7. FAIR VALUE MEASUREMENTS AND DISCLOSURE

The Fair Value Measurement and Disclosure framework in ASC 820, “Fair Value Measurement,” provides a three-tiered fair value hierarchy based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs and Level 3 includes fair values estimated using significant unobservable inputs.

The level of an asset or liability within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Our valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs.

The valuation methodologies described above may produce a fair value calculation that may not be indicative of future net realizable value or reflective of future fair values. We believe our valuation methods are appropriate and consistent with other market participants. The use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. There have been no changes in the methodologies used since December 31, 2023.

Long-Term Debt and Other Financial Instruments

The carrying amounts and estimated fair values of our long-term debt, including current maturities, and other financial instruments are summarized as follows:

The carrying amount of debt with an original maturity of less than one year approximates fair value. The fair value measurements used for notes and debentures are considered Level 2 and are determined using various methods, including quoted prices for identical or similar securities in both active and inactive markets.

Following is the fair value leveling for investment securities that are measured at fair value and derivatives as of June 30, 2024 and December 31, 2023. Derivatives designated as hedging instruments are reflected as “Prepaid and other current assets,” “Other Assets,” “Accounts payable and accrued liabilities,” and “Other noncurrent liabilities” on our consolidated balance sheets.

Investment Securities

Our investment securities include both equity and debt securities that are measured at fair value, as well as equity securities without readily determinable fair values. A substantial portion of the fair values of our investment securities is estimated based on quoted market prices. Investments in equity securities not traded on a national securities exchange are valued at cost, less any impairment, and adjusted for changes resulting from observable, orderly transactions for identical or similar securities. Investments in debt securities not traded on a national securities exchange are valued using pricing models, quoted prices of securities with similar characteristics or discounted cash flows.

The components comprising total gains and losses in the period on equity securities are as follows:

At June 30, 2024, available-for-sale debt securities totaling $1,169 have maturities as follows - less than one year: $62; one to three years: $192; three to five years: $116; five or more years: $799.

Our cash equivalents (money market securities), short-term investments (certificate and time deposits) and nonrefundable customer deposits are recorded at amortized cost, and the respective carrying amounts approximate fair values. Short-term investments and nonrefundable customer deposits are recorded in “Prepaid and other current assets” and our investment securities are recorded in “Other Assets” on the consolidated balance sheets.

Derivative Financial Instruments

We enter into derivative transactions to manage certain market risks, primarily interest rate risk and foreign currency exchange risk. This includes the use of interest rate swaps, interest rate locks, foreign exchange forward contracts and combined interest rate foreign exchange contracts (cross-currency swaps). We do not use derivatives for trading or speculative purposes. We record derivatives on our consolidated balance sheets at fair value that is derived from observable market data, including yield curves and foreign exchange rates (all of our derivatives are Level 2). Cash flows associated with derivative instruments are presented in the same category on the consolidated statements of cash flows as the item being hedged.

Fair Value Hedging Periodically, we enter into and designate fixed-to-floating interest rate swaps as fair value hedges. The purpose of these swaps is to manage interest rate risk by managing our mix of fixed-rate and floating-rate debt. These swaps involve the receipt of fixed-rate amounts for floating interest rate payments over the life of the swaps without exchange of the underlying principal amount.

We also designate most of our cross-currency swaps and foreign exchange contracts as fair value hedges. The purpose of these contracts is to hedge foreign currency risk associated with changes in spot rates on foreign denominated debt. For cross-currency hedges, we have elected to exclude the change in fair value of the swap related to both time value and cross-currency basis spread from the assessment of hedge effectiveness. For foreign exchange contracts, we have elected to exclude the change in fair value of forward points from the assessment of hedge effectiveness.

Unrealized and realized gains or losses from fair value hedges impact the same category on the consolidated statements of income as the item being hedged, including the earnings impact of excluded components. In instances where we have elected to exclude components from the assessment of hedge effectiveness related to fair value hedges, unrealized gains or losses on such excluded components are recorded as a component of accumulated OCI and recognized into earnings over the life of the hedging instrument. Unrealized gains on derivatives designated as fair value hedges are recorded at fair value as assets, and unrealized losses are recorded at fair market value as liabilities. Except for excluded components, changes in the fair value of derivative instruments designated as fair value hedges are offset against the change in fair value of the hedged assets or liabilities through earnings. In the six months ended June 30, 2024 and 2023, no ineffectiveness was measured on fair value hedges.

Cash Flow Hedging We designate some of our cross-currency swaps as cash flow hedges to hedge our exposure to variability in expected future cash flows that are attributable to foreign currency risk and interest rate risk generated from our foreign-denominated debt. These agreements include initial and final exchanges of principal from fixed foreign denominated amounts to fixed U.S. dollar denominated amounts, to be exchanged at a specified rate that is usually determined by the market spot rate upon issuance. They also include an interest rate swap of a fixed or floating foreign denominated interest rate to a fixed U.S. dollar denominated interest rate.

Unrealized gains on derivatives designated as cash flow hedges are recorded at fair value as assets and unrealized losses are recorded at fair value as liabilities. For derivative instruments designated as cash flow hedges, changes in fair value are reported as a component of accumulated OCI and are reclassified into the consolidated statements of income in the same period the hedged transaction affects earnings.

Periodically, we enter into and designate interest rate locks to partially hedge the risk of changes in interest payments attributable to increases in the benchmark interest rate during the period leading up to the probable issuance of fixed-rate debt. We designate our interest rate locks as cash flow hedges. Gains and losses when we settle our interest rate locks are amortized into income over the life of the related debt. Over the next 12 months, we expect to reclassify $59 from accumulated OCI to “Interest expense” due to the amortization of net losses on historical interest rate locks.

Collateral and Credit-Risk Contingency We have entered into agreements with our derivative counterparties establishing collateral thresholds based on respective credit ratings and netting agreements. At June 30, 2024, we had posted collateral of $680 (a deposit asset) and held collateral of $0 (a receipt liability). Under the agreements, if AT&T’s credit rating had been downgraded two ratings levels by Fitch Ratings, one level by S&P and one level by Moody’s before the final collateral exchange in June, we would have been required to post additional collateral of $50. If AT&T’s credit rating had been downgraded three ratings levels by Fitch Ratings, two levels by S&P, and two levels by Moody’s, we would have been required to post additional collateral of $3,594. At December 31, 2023, we had posted collateral of $670 (a deposit asset) and held collateral of $5 (a receipt liability). We do not offset the fair value of collateral, whether the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) exists, against the fair value of the derivative instruments.

Following are the notional amounts of our outstanding derivative positions:

Following are the related hedged items affecting our financial position and performance:

In addition, the net swap settlements that accrued and settled in the periods above were offset against “Interest expense.”

The following table presents information for our cash flow hedging relationships:

NOTE 8. SALES OF RECEIVABLES

We have agreements with various third-party financial institutions pertaining to the sales of certain types of our accounts receivable. The most significant of these programs are discussed in detail below and generally consist of (1) receivables arising from equipment installment plans, which are sold for cash and beneficial interests, such as deferred purchase price, when applicable, and (2) revolving trade receivables, which are sold for cash. Under the terms of our agreements for these programs, we continue to service the transferred receivables on behalf of the financial institutions.

The following table sets forth a summary of cash proceeds received, net of remittances paid, from sales of receivables:

The sales of receivables did not have a material impact on our consolidated statements of income or to “Total Assets” reported on our consolidated balance sheets. We reflect cash receipts on sold receivables as cash flows from operations in our consolidated statements of cash flows. In the event cash is received on the beneficial interests, those receipts are classified as cash flows from investing activities, when applicable.

Our equipment installment and revolving receivables programs are discussed in detail below. The following table sets forth a summary of the receivables and accounts being serviced:

Equipment Installment Receivables Program

We offer our customers the option to purchase certain wireless devices in installments over a specified period of time and, in many cases, once certain conditions are met, they may be eligible to trade in the original equipment for a new device and have the remaining unpaid balance paid or settled.

We maintain a program under which we transfer a portion of these receivables through our bankruptcy-remote subsidiary in exchange for cash and beneficial interests. In the event a customer trades in a device prior to the end of the installment contract period, we agree to make a payment to the financial institutions equal to any outstanding remaining installment receivable balance. Accordingly, we record a guarantee obligation for this estimated amount at the time the receivables are transferred.

The following table sets forth a summary of equipment installment receivables sold under this program:

Beneficial interests, when applicable, and guarantee obligations are initially recorded at estimated fair value and subsequently adjusted for changes in present value of expected cash flows. The estimation of their fair values is based on remaining installment payments expected to be collected and the expected timing and value of device trade-ins. The estimated value of the device trade-ins considers prices offered to us by independent third parties and contemplates changes in value after the launch of a device model. The fair value measurements used for the beneficial interests and the guarantee obligation are considered Level 3 under the Fair Value Measurement and Disclosure framework (see Note 7).

The following table presents the previously transferred equipment installment receivables, which we repurchased in exchange for the associated beneficial interests:

At June 30, 2024 and December 31, 2023, our beneficial interests were $2,764 and $2,270, respectively, of which $1,639 and $1,296 are included in “Prepaid and other current assets” on our consolidated balance sheets, with the remainder in “Other Assets.” The guarantee obligation at June 30, 2024 and December 31, 2023 was $299 and $385, respectively, of which $106 and $111 are included in “Accounts payable and accrued liabilities” on our consolidated balance sheets, with the remainder in “Other noncurrent liabilities.” Our maximum exposure to loss as a result of selling these equipment installment receivables is limited to the total amount of our beneficial interests and guarantee obligation.

Revolving Receivables Program

During the first quarter of 2024, we expanded our revolving agreement to transfer up to $1,800 of certain receivables through our bankruptcy-remote subsidiaries to various financial institutions on a recurring basis in exchange for cash equal to the gross receivables transferred. This agreement is subject to renewal on an annual basis and the transfer limit may be expanded or reduced from time to time. As customers pay their balances, we transfer additional receivables into the program, resulting in our gross receivables sold exceeding net cash flow impacts (e.g., collect and reinvest). The transferred receivables are fully guaranteed by our bankruptcy-remote subsidiaries, which hold additional receivables in the amount of $1,260 that are pledged as collateral under this agreement. The transfers are recorded at fair value of the proceeds received and obligations assumed less derecognized receivables. Our maximum exposure to loss related to these receivables transferred is limited to the derecognized amount outstanding.

The following table sets forth a summary of the revolving receivables sold:

NOTE 9. TRANSACTIONS WITH DIRECTV

We account for our investment in DIRECTV under the equity method and record our share of DIRECTV earnings as equity in net income of affiliates, with DIRECTV considered a related party.

At June 30, 2024, our investment in DIRECTV was $293. The following table sets forth our share of DIRECTV’s earnings included in “Equity in net income of affiliates” and cash distributions received from DIRECTV:

For the three and six months ended June 30, 2024, we billed DIRECTV approximately $134 and $279 under commercial arrangements and transition service agreements, which were recorded as a reduction to the operations and support expenses incurred.

At June 30, 2024, we had accounts receivable from DIRECTV of $247 and accounts payable to DIRECTV of $50.

We are not committed, implicitly or explicitly, to provide financial or other support, other than as noted above, as our involvement with DIRECTV is limited to the carrying amount of the assets and liabilities recognized on our consolidated balance sheet.

NOTE 10. SUPPLIER AND VENDOR FINANCING PROGRAMS

Supplier Financing Program

We actively manage the timing of our supplier payments for operating items to optimize the use of our cash and seek to make payments on 90-day or greater terms, while providing suppliers with access to bank facilities that permit earlier payment at their cost. Our supplier financing program does not result in changes to our normal, contracted payment cycles or cash from operations.

At the supplier’s election, they can receive payment of AT&T obligations prior to the scheduled due dates, at a discounted price from the third-party financial institution. The discounted price paid by participating suppliers is based on a variable rate that is indexed to the overnight borrowing rate. We agree to pay the financial institution the stated amount generally within 90 days of receipt of the invoice. We do not have pledged assets or other guarantees under our supplier financing program.

Suppliers had elected to sell to the third-party financial institutions $3,059 and $2,844 of our outstanding payment obligations as of June 30, 2024 and December 31, 2023, respectively. These amounts are included in “Accounts payable and accrued liabilities” on our consolidated balance sheets. Our supplier financing programs are reported as operating or investing (when capitalizable) activities in our statements of cash flows when paid.

Direct Supplier Financing

We also have arrangements with suppliers of handset inventory that allow us to extend the stated payment terms by up to 90 days at an additional cost to us (variable rate extension fee). We had $3,432 of direct supplier financing outstanding at June 30, 2024 and $5,442 as of December 31, 2023, which are included in “Accounts payable and accrued liabilities” on our consolidated balance sheets. Our direct supplier financing is reported as operating activities in our statements of cash flows when paid.

Vendor Financing

In connection with capital improvements and the acquisition of other productive assets, we negotiate favorable payment terms of 120 days or more (referred to as vendor financing), which are reported as financing activities in our statements of cash flows when paid. For the six months ended June 30, 2024 and 2023, we recorded vendor financing commitments related to capital investments of $523 and $1,341, respectively. We had $1,827 of vendor financing payables at June 30, 2024, with $883 included in “Accounts payable and accrued liabilities” and $2,833 of vendor financing payables at December 31, 2023, with $1,975 included in “Accounts payable and accrued liabilities.”
