Dallas, Texas

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of AT&T Savings and Security Plan (Plan) as of December 31, 2023 and 2022, the related statement of changes in net assets available for benefits for the year ended December 31, 2023, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of AT&T Savings and Security Plan as of December 31, 2023 and 2022, and the changes in net assets available for benefits for the year ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

Basis of Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Report on Supplemental Information

The supplemental information in the accompanying schedule of assets (held at end of year) as of December 31, 2023, has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental schedule is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental schedule reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental schedule. In forming our opinion on the supplemental schedule, we evaluated whether the supplemental schedule, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the basic financial statements taken as a whole.

NOTE 1. PLAN DESCRIPTION

The AT&T Savings and Security Plan (Plan) is a defined contribution plan originally established by SBC Communications Inc. (SBC) to provide a convenient way for eligible employees to save on a regular and long-term basis.

The majority of eligible employees are represented by the Communications Workers of America who are employed by participating companies of AT&T. The following description of the Plan provides only general information. The Plan has detailed provisions covering participant eligibility, participant allotments from pay, participant withdrawals, participant loans, employer contributions and related vesting of contributions and Plan expenses. The Plan text and prospectus include complete descriptions of these and other Plan provisions. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA).

The Bank of New York Mellon Corporation (BNY Mellon) serves as the trustee for the Plan. Fidelity Investments Institutional Operations Company, Inc. (Fidelity) serves as recordkeeper for the Plan.

During 2023 and 2022, participants could invest their contributions in one or more of nine funds in 1% increments:

•    AT&T Shares Fund	•    Global Equity Fund
•    Bond Fund	•    Mid and Small Cap Stock Fund
•    Large Cap Stock Fund	•    International Stock Fund
•    Interest Income Fund	•    Warner Bros. Discovery Stock Fund *
•    AT&T Age-Based Asset Allocation Funds (based on retirement date)**

* Effective as of market close on April 8, 2022, the Warner Bros. Discovery Stock Fund was added to the Plan as a result of the sale of the WarnerMedia business. Effective as of market close on April 10, 2023, the fund was removed from the Plan.

** Effective as of market close on December 30, 2022, the AT&T Age-Based Asset Allocation Funds were added to the Plan.

Participants contribute to the Plan through payroll allotments. Participants may also contribute amounts representing distributions from other qualified defined benefit and defined contribution plans (rollovers). The Company contributes to the Plan by matching the participants’ contributions based on the provisions of the Plan. Company matching contributions are made solely in the form of shares of AT&T’s common stock held in an Employee Stock Ownership Plan (ESOP), which is part of the AT&T Shares Fund, within this Plan. Matching contributions made to the Plan can be immediately diversified into any of the fund options above.

Dividends on shares in the AT&T Shares Fund can either be reinvested in the AT&T Shares Fund on a quarterly basis, or paid into a short-term interest bearing fund for distribution before the end of the year. Interest earned on dividends held in the short-term interest-bearing fund are used to purchase additional units of the AT&T Shares Fund in the participant’s account. During 2023, Plan participants elected to receive $3,412 in dividend distributions. This amount is included in distributions on the Plan’s Statement of Changes in Net Assets Available for Benefits.

Each participant is entitled to exercise voting rights attributable to the AT&T shares allocated to their account and is notified by the Company prior to the time that such rights may be exercised. Subject to the fiduciary provisions of ERISA, the trustee will not vote any allocated shares for which instructions have not been given by a participant. The trustee votes any unallocated shares in the same proportion as it votes those shares that were allocated to the extent the proportionate vote is consistent with the trustee’s fiduciary obligations under ERISA. Participants have the same voting rights in the event of a tender or exchange offer.

Although it has not expressed any intent to do so, AT&T has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA and collective bargaining obligations. In the event that the Plan is terminated, subject to the conditions set forth by ERISA, the account balances of all participants shall be 100% vested.

On April 8, 2022, AT&T completed the separation and distribution of its WarnerMedia business, and merger of a wholly-owned subsidiary of AT&T formed to hold the WarnerMedia business, with a subsidiary of Discovery, Inc. The transaction resulted in the creation of a new Warner Bros. Discovery Stock Fund in the Plan to hold the new Warner Bros. Discovery common stock received as part of the transaction. The fund remained in the Plan as a temporary investment option until it was removed from the Plan on April 10, 2023.

Administrative Expenses The reasonable expenses of plan administration may be charged to the Plan in accordance with procedures adopted by the Plan administrator (as defined by the Plan). Brokerage fees, transfer taxes and other expenses incident to the purchase or sale of securities by the Trustee shall be deemed to be part of the cost of such securities, or deducted in computing the proceeds, as the case may be. Taxes, if any, on any assets held or income received by the Trustee will be charged appropriately against the accounts of Plan participants as determined by the Plan administrator. To the extent that expenses incident to the administration of the Plan are paid from the Plan, the Plan administrator will determine which expenses are to be charged to and paid from participant’s individual accounts, which expenses are to be charged to and paid from the accounts of all participants (and how they are to be allocated among such accounts), and which expenses are to be charged to and paid from the accounts of one or more identified groups of participants (and how they are to be allocated among such accounts). All expenses of administering the Plan that are not charged to the Plan will be borne by the Company.

NOTE 2. ACCOUNTING POLICIES

The accompanying financial statements were prepared in conformity with U.S. generally accepted accounting principles (GAAP), which require management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Distributions are recorded when paid.

Investment Valuation and Income Recognition Investments are stated at fair value, except those investments that are fully benefit-responsive investments, which are stated at contract value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. See Note 3 for discussion of fair value measurements. Investments in securities traded on a national securities exchange are valued at the last reported sales price on the last business day of the year. If no sale was reported on that date, they are valued at the last reported bid price. Shares of registered investment companies (i.e., mutual funds) are valued based on quoted market prices, which represent the net asset value of shares held at year-end. Common/collective trust funds are valued at quoted redemption values that represent the net asset values of units held at year-end.

Investment contracts held by a defined contribution plan are required to be reported at contract value. Contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. The Plan invests in fully benefit-responsive synthetic guaranteed investment contracts (Synthetic GICs). The underlying investments of the Synthetic GICs are comprised of corporate bonds and notes, registered investment companies and government securities. The contract value of the fully benefit-responsive investment contracts represents contributions plus earnings, less participant withdrawals and administrative expenses.

Purchases and sales of securities are reflected as of the trade date. Dividend income is recognized on the ex-dividend date. Interest earned on investments is recognized on the accrual basis. Net appreciation (depreciation) includes the Plan’s gains and losses on investments bought and sold as well as held during the year. Transfers in and out of Level 1 (quoted market prices), Level 2 (other significant observable inputs) and Level 3 (significant unobservable inputs) are recognized on the period ending date.

Notes Receivable from Participants Notes receivable from participants represent participant loans that are recorded at their unpaid principal balance plus any accrued, but unpaid interest. Interest income on notes receivable from participants is recorded when it is earned. Related fees are recorded as administrative expenses and are expensed when they are incurred. No allowance for credit losses has been recorded as of December 31, 2023 or 2022. If a participant ceases to make loan repayments and the Plan administrator deems the participant loan to be a distribution, the participant loan balance is reduced and a distribution is recorded.

NOTE 3. FAIR VALUE MEASUREMENTS

Accounting Standards Codification 820, Fair Value Measurement, establishes a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1    Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

Level 2    Inputs to the valuation methodology include:

•    Quoted prices for similar assets and liabilities in active markets;

•    Quoted prices for identical or similar assets or liabilities in inactive markets;

•    Inputs other than quoted market prices that are observable for the asset or liability;

•    Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3    Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

The valuation methodologies described in Note 2 may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while Plan management believes its 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 at December 31, 2023 and 2022.

The following table sets forth by level, within the fair value hierarchy, the Plan’s investments at fair value as of December 31, 2023:

	Plan Assets at Fair Value as of December 31, 2023

NOTE 4. INVESTMENTS

Fully Benefit-Responsive Investment Contracts

The Interest Income Fund consists of fully benefit-responsive investment contracts with various financial institutions and insurance companies that promise to repay principal plus accrued income at contract maturity, subject to the creditworthiness of the issuer. Interest crediting rates are generally established when the contract is purchased and are periodically reset. The Interest Income Fund invests in Synthetic GICs, also referred to as wrapper contracts. The assets supporting the Synthetic GICs are owned by the Plan and generally consist of high quality fixed income securities.

A bank or insurance company issues a wrapper contract that provides preservation of principal, maintains a stable interest rate and provides daily liquidity at contract value for participant directed transactions, in accordance with the provisions of the Plan. Wrapper contracts amortize the realized and unrealized gains and losses on the underlying fixed income investments through adjustments to the future interest crediting rate. The issuer of the wrapper contract provides assurance that the adjustments to the interest crediting rate do not result in a future interest crediting rate that is less than zero, which would result in a loss of principal or accrued interest.

In certain circumstances, the amount withdrawn from the wrapper contract could be payable at fair value rather than at contract value. These events include termination of the Plan, a material adverse change to the provisions of the Plan, if AT&T elects to withdraw from a wrapper contract in order to switch to a different investment provider or, in the event of a spin-off or sale of a division, if the terms of the successor plan do not meet the contract issuers’ underwriting criteria for issuance of a clone wrapper contract. Events that would permit a wrapper contract issuer to terminate a wrapper contract upon short notice include the Plan’s loss of its qualified status, un-cured material breaches of responsibilities or material and adverse changes to the provisions of the Plan. The Company does not believe any of these events are probable of occurring in the foreseeable future.

Interest Bearing Cash

At December 31, 2023 and 2022, the Plan held approximately $2,538 and $2,541, respectively, of unallocated interest bearing cash related to contributions, uncashed checks and fees pending allocation to participant accounts or clearance through the plan funds.

Investment Risk

Investments held by the Plan are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investments, it is at least reasonably possible that changes in the values of investments could occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefit. Plan participants’ accounts that are invested in the Company stock fund option are exposed to market risk in the event of a significant decline in the value of AT&T stock.

Additionally, the Plan invests in securities with contractual cash flows, such as asset-backed securities, collateralized mortgage obligations and commercial mortgage-backed securities. The value, liquidity and related income of these securities are sensitive to changes in economic conditions, including real estate values, delinquencies or defaults, or both, and may be adversely affected by shifts in the market’s perception of the issuers and changes in interest rates.

NOTE 5. PARTIES-IN-INTEREST TRANSACTIONS

Plan assets are invested in AT&T stock directly. Because the Company is the plan sponsor, transactions involving the Company’s stock qualify as party-in-interest transactions. In addition, certain investments held by the Plan are managed by BNY Mellon and Fidelity as trustee and record keeper, respectively, as defined by various agreements. Therefore, these transactions and fees paid to these entities qualify as parties-in-interest transactions. All of these transactions are exempt from the prohibited transaction rules.

The Plan may, at the discretion of the Plan’s participants or via the Company match, invest its assets in the Company’s common stock. The Plan held 15,279,458 and 15,834,876 shares of the Company’s common stock in the AT&T Shares Fund as of December 31, 2023 and 2022, respectively. Dividends earned by the Plan’s AT&T Shares Fund on the Company’s common stock were $13,816 for the year ended December 31, 2023.

NOTE 6. TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service (IRS) dated June 23, 2015, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (IRC) and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the IRC to maintain its qualification. Subsequent to this determination by the IRS, the Plan was amended. The Plan administrator has indicated that it will take the necessary steps, if any, to bring the Plan’s operations into compliance with the Code.

Accounting principles generally accepted in the United States require Plan management to evaluate uncertain tax positions taken by the Plan. The financial statement effects of a tax position are recognized when the position is more likely than not, based on the technical merits, to be sustained upon examination by the IRS. The Plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2023, there were no uncertain positions taken or expected to be taken. The Plan has recognized no interest or penalties related to uncertain tax positions. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.
