Derivative Financial Instruments

In the normal course of operations, Group Trust assets and liabilities held in the AT&T Stable Value Fund (Stable Value Fund) may include derivative financial instruments (futures and foreign currency forward contracts). These instruments involve, in varying degrees, elements of credit and market volatility risks in excess of more traditional investment holdings such as equity and debt instruments. The intent is to use derivative financial instruments as an economic hedge to manage market volatility and foreign currency exchange rate risk associated with the Stable Value Fund’s investment assets. The gains (losses) are located on the Statement of Changes in Net Assets Available for Benefits as Net Loss from Investment in AT&T Savings Plan Master Trust to the extent of the Plans’ ownership in the AT&T Master Trust. The Group Trust’s fiduciaries do not anticipate any material adverse effect on the Group Trust’s financial position resulting from its involvement in these instruments.

At December 31, 2025 and 2024, the fair value of derivative financial instruments held by the AT&T Master Trust was not material.
Futures Contracts

The primary risk managed by the Group Trust using futures contracts is the price risk associated with investments. On behalf of the AT&T Master Trust, investment managers for the Group Trust enter into various futures contracts to economically hedge investments in domestic securities. These contracts, which are considered derivatives under ASC Topic 815, Derivatives and Hedging are agreements between two parties to buy or sell a security or financial interest at a set price on a future date and are standardized and exchange-traded. Upon entering into such a contract on behalf of the Group Trust, the investment manager is required to pledge to the broker an amount of cash or securities equal to the minimum “initial margin” requirements of the exchange on which the contract is traded. Pursuant to the contract, the investment manager agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded on a daily basis by the trustee as a realized gain or loss equal to the difference in the value of the contract between daily closing prices. Upon entering into such contracts, the Group Trust bears the risk of interest or exchange rates or securities prices moving unexpectedly, in which case, the Group Trust may not achieve the anticipated benefits of the futures contracts and may realize a loss. With futures, there is minimal counterparty credit risk to the Group Trust since futures are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees the futures against default. The investments in the Group Trust are subject to equity price risk and interest rate risk, in the normal course of pursuing its investment objectives. The U.S. interest rate futures held in the portfolio as of December 31, 2025 and 2024 were used primarily to hedge and manage the duration risk of the portfolio.

Foreign Currency Contracts

The primary risks managed by the Group Trust using foreign currency forward contracts is the foreign currency exchange rate risk associated with the Group Trust’s investments denominated in foreign currencies. On behalf of the AT&T Master Trust, investment managers for the Group Trust enter into forward foreign currency contracts, which are agreements to exchange foreign currencies at a specified future date at a specified rate, the terms of which are not standardized on an exchange. These contracts are intended to minimize the effect of currency fluctuations on the performance of investments denominated in foreign currencies. Although in some cases, forward foreign currency contracts are used to express a view on the direction of a particular currency, risk arises both from the possible inability of the counterparties to meet the terms of the contracts (credit risk) and from movement in foreign currency exchange rates (market risk). Foreign currency forward contracts are entered into with major banks to minimize credit risk, and accordingly, no credit reserve has been established against these amounts. The contracts are recorded at fair value on the date the contract is entered into, which is typically zero.

The fair value of the foreign currency contracts are disclosed in unsettled trades and other of the Group Trust and are included in the Statement of Net Assets Available for Benefits to the extent of the Plans’ ownership in the AT&T Master Trust.

Fully Benefit-Responsive Investment Contracts

The Stable Value Fund consists of fully benefit-responsive investment contracts with various financial institutions and insurance companies which can be accounted for by the Plan at contract value. Generally contract value represents contributions made under the contract, plus earnings, less participant withdrawals and administrative expenses. The investments held by the Stable Value Fund as of December 31, 2025 and 2024 include Synthetic GICs which are fully benefit-responsive investment contracts. Synthetic GICs are constructed by combining a stable value insurance wrapper contract and a fixed income portfolio. The assets supporting the Synthetic GICs are owned by the Group Trust and generally consist of high quality fixed income securities. Traditional Guaranteed Investment Contracts (“Traditional GICs” also known as “General Account GICs”) are issued by insurance companies and typically pay a guaranteed fixed or floating rate of interest over the life of the contract with a repayment of principal at maturity. A Synthetic GIC is similar to a Traditional GIC but has unbundled the insurance and investment components of the Traditional GIC.

Wrapper contracts are typically issued by a bank or insurance company, and seek to provide preservation of principal by permitting daily liquidity at contract value for participant directed transactions, in accordance with the provisions of the Plans. Wrapper contracts amortize the realized and unrealized gains and losses on the underlying fixed income investments through adjustments to the future interest crediting rate of the contract. Wrapper contracts typically contain contractual provisions that prevent the interest crediting rate from falling below zero.

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 Plans, a material adverse change to the provisions of the Plans, 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 Plans’ loss of qualified status, un-cured material breaches of responsibilities or material and adverse changes to the provisions of the Plans. The Company does not believe any of the events are probable of occurring in the foreseeable future.

Interest Bearing Cash

At December 31, 2025 and 2024, ARSP held approximately $21,932 and $25,210, respectively, and ARSP-PR held approximately $78 and $122, 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 Group Trust and the AT&T Master Trust 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 benefits. Participants’ accounts that are invested in funds holding AT&T stock are exposed to market risk in the event of a significant decline in the value of AT&T stock.
Additionally, the Group Trust 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 value, 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.

Derivative Financial Instruments

In the normal course of operations, Group Trust assets and liabilities held in the AT&T Stable Value Fund (Stable Value Fund) may include derivative financial instruments (futures and foreign currency forward contracts). These instruments involve, in varying degrees, elements of credit and market volatility risks in excess of more traditional investment holdings such as equity and debt instruments. The intent is to use derivative financial instruments as an economic hedge to manage market volatility and foreign currency exchange rate risk associated with the Stable Value Fund’s investment assets. The gains (losses) are located on the Statement of Changes in Net Assets Available for Benefits as Net Loss from Investment in AT&T Savings Plan Master Trust to the extent of the Plans’ ownership in the AT&T Master Trust. The Group Trust’s fiduciaries do not anticipate any material adverse effect on the Group Trust’s financial position resulting from its involvement in these instruments.

At December 31, 2025 and 2024, the fair value of derivative financial instruments held by the AT&T Master Trust was not material.
Futures Contracts

The primary risk managed by the Group Trust using futures contracts is the price risk associated with investments. On behalf of the AT&T Master Trust, investment managers for the Group Trust enter into various futures contracts to economically hedge investments in domestic securities. These contracts, which are considered derivatives under ASC Topic 815, Derivatives and Hedging are agreements between two parties to buy or sell a security or financial interest at a set price on a future date and are standardized and exchange-traded. Upon entering into such a contract on behalf of the Group Trust, the investment manager is required to pledge to the broker an amount of cash or securities equal to the minimum “initial margin” requirements of the exchange on which the contract is traded. Pursuant to the contract, the investment manager agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded on a daily basis by the trustee as a realized gain or loss equal to the difference in the value of the contract between daily closing prices. Upon entering into such contracts, the Group Trust bears the risk of interest or exchange rates or securities prices moving unexpectedly, in which case, the Group Trust may not achieve the anticipated benefits of the futures contracts and may realize a loss. With futures, there is minimal counterparty credit risk to the Group Trust since futures are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees the futures against default. The investments in the Group Trust are subject to equity price risk and interest rate risk, in the normal course of pursuing its investment objectives. The U.S. interest rate futures held in the portfolio as of December 31, 2025 and 2024 were used primarily to hedge and manage the duration risk of the portfolio.

Foreign Currency Contracts

The primary risks managed by the Group Trust using foreign currency forward contracts is the foreign currency exchange rate risk associated with the Group Trust’s investments denominated in foreign currencies. On behalf of the AT&T Master Trust, investment managers for the Group Trust enter into forward foreign currency contracts, which are agreements to exchange foreign currencies at a specified future date at a specified rate, the terms of which are not standardized on an exchange. These contracts are intended to minimize the effect of currency fluctuations on the performance of investments denominated in foreign currencies. Although in some cases, forward foreign currency contracts are used to express a view on the direction of a particular currency, risk arises both from the possible inability of the counterparties to meet the terms of the contracts (credit risk) and from movement in foreign currency exchange rates (market risk). Foreign currency forward contracts are entered into with major banks to minimize credit risk, and accordingly, no credit reserve has been established against these amounts. The contracts are recorded at fair value on the date the contract is entered into, which is typically zero.

The fair value of the foreign currency contracts are disclosed in unsettled trades and other of the Group Trust and are included in the Statement of Net Assets Available for Benefits to the extent of the Plans’ ownership in the AT&T Master Trust.

Fully Benefit-Responsive Investment Contracts

The Stable Value Fund consists of fully benefit-responsive investment contracts with various financial institutions and insurance companies which can be accounted for by the Plan at contract value. Generally contract value represents contributions made under the contract, plus earnings, less participant withdrawals and administrative expenses. The investments held by the Stable Value Fund as of December 31, 2025 and 2024 include Synthetic GICs which are fully benefit-responsive investment contracts. Synthetic GICs are constructed by combining a stable value insurance wrapper contract and a fixed income portfolio. The assets supporting the Synthetic GICs are owned by the Group Trust and generally consist of high quality fixed income securities. Traditional Guaranteed Investment Contracts (“Traditional GICs” also known as “General Account GICs”) are issued by insurance companies and typically pay a guaranteed fixed or floating rate of interest over the life of the contract with a repayment of principal at maturity. A Synthetic GIC is similar to a Traditional GIC but has unbundled the insurance and investment components of the Traditional GIC.

Wrapper contracts are typically issued by a bank or insurance company, and seek to provide preservation of principal by permitting daily liquidity at contract value for participant directed transactions, in accordance with the provisions of the Plans. Wrapper contracts amortize the realized and unrealized gains and losses on the underlying fixed income investments through adjustments to the future interest crediting rate of the contract. Wrapper contracts typically contain contractual provisions that prevent the interest crediting rate from falling below zero.

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 Plans, a material adverse change to the provisions of the Plans, 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 Plans’ loss of qualified status, un-cured material breaches of responsibilities or material and adverse changes to the provisions of the Plans. The Company does not believe any of the events are probable of occurring in the foreseeable future.

Interest Bearing Cash

At December 31, 2025 and 2024, ARSP held approximately $21,932 and $25,210, respectively, and ARSP-PR held approximately $78 and $122, 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 Group Trust and the AT&T Master Trust 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 benefits. Participants’ accounts that are invested in funds holding AT&T stock are exposed to market risk in the event of a significant decline in the value of AT&T stock.
Additionally, the Group Trust 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 value, 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.
