**PART I**

**ITEM 1. BUSINESS**

**GENERAL**

AT&T Inc. ("AT&T," "we" or the "Company") is a holding company incorporated under the laws of the State of Delaware in 1983 and has its principal executive offices at 208 S. Akard St., Dallas, Texas, 75202 (telephone number 210-821-4105). We maintain an internet website at www.att.com. (This website address is for information only and is not intended to be an active link or to incorporate any website information into this document.) We file electronically with the Securities and Exchange Commission (SEC) required reports on Form 8-K, Form 10-Q and Form 10-K; proxy materials; registration statements on Forms S-3 and S-8, as necessary; and other forms or reports as required. The SEC maintains a website (www.sec.gov) that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC. We make available, free of charge, on our website our annual report on Form 10-K, our quarterly reports on Form 10-Q, current reports on Form 8-K and all amendments to those reports as soon as reasonably practicable after such reports are electronically filed with, or furnished to, the SEC. We also make available on that website, and in print, if any stockholder or other person so requests, our "Code of Ethics" applicable to all employees and Directors, our "Corporate Governance Guidelines," and the charters for all committees of our Board of Directors, including Audit, Human Resources and Governance and Policy committees. Any changes to our Code of Ethics or waiver of our Code of Ethics for senior financial officers, executive officers or Directors will be posted on that website.

A reference to a "Note" refers to the Notes to Consolidated Financial Statements in Item 8.

**History**

AT&T, formerly known as SBC Communications Inc. (SBC), was formed as one of several regional holding companies created to hold AT&T Corp.'s (ATTC) local telephone companies. On January 1, 1984, we were spun-off from ATTC pursuant to an anti-trust consent decree, becoming an independent publicly traded telecommunications services provider.

Following our formation, we expanded our communications footprint and operations, most significantly:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our subsidiaries merged with incumbent local exchange carriers (ILEC) Pacific Telesis Group in 1997 and Ameritech Corporation in 1999.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In 2005, we merged one of our subsidiaries with ATTC, creating one of the world's leading telecommunications providers. In connection with the merger, we changed the name of our company from "SBC Communications Inc." to "AT&T Inc."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In 2006, we acquired ILEC BellSouth Corporation (BellSouth), which included BellSouth's 40% economic interest in AT&T Mobility LLC (AT&T Mobility), formerly Cingular Wireless LLC, resulting in 100% ownership of AT&T Mobility.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In 2014, we completed the acquisition of wireless provider Leap Wireless International, Inc.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In 2015, we acquired wireless properties in Mexico and acquired DIRECTV, a leading provider of digital television entertainment services in both the United States (included in our former Video business) and Latin America (referred to as Vrio, which was sold in November 2021).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In July 2021, we closed our transaction with TPG Capital (TPG) to form a new company named DIRECTV Entertainment Holdings, LLC (DIRECTV). With the close of the transaction (DIRECTV Transaction), we separated our Video business, comprised of our U.S. video operations, and began accounting for our investment in DIRECTV under the equity method. In July 2025, we sold our remaining interest in DIRECTV to TPG.

**General**

We are a leading provider of telecommunications and technology services globally. The services and products that we offer vary by market and utilize various technology platforms in a range of geographies. Our reportable segments are organized as follows:

The ***Communications segment*** provides wireless and wireline telecom and broadband services to consumers located in the United States 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, fixed wireless services, IP Voice and managed professional services, as well as legacy voice and data services and related equipment, to business customers.

• **Consumer Wireline** provides broadband services, including fiber connections that provide multi-gig services, and our fixed wireless access product (AT&T Internet Air or "AIA") that provides internet services delivered over our 5G wireless network, to residential customers in select locations. Consumer Wireline also provides legacy telephony voice communication services.

The ***Latin America segment*** provides wireless service and equipment in Mexico.

Corporate support costs, including administrative support costs borne by AT&T where business units do not influence decision making, and results from business no longer integral to our operations are reported as *Corporate* and *Other*, which reconciles our segment results to consolidated operating income and income before income taxes.

**Areas of Focus**

We are a leader in providing connectivity services through our market focus areas of 5G and fiber. Fiber underpins the connectivity we deliver, both wired and wireless. Building on that fiber foundation is our solid spectrum portfolio, strengthened through Federal Communications Commission (FCC) auctions, other spectrum acquisitions and 5G deployment. We believe our fixed wireline and mobile approach will differentiate our services and provide us with additional convergence growth opportunities in the future as bandwidth demands continue to grow. We will continue to demonstrate our commitment to ensure management attention is sharply focused on growth areas and operational efficiencies.

Our integrated telecommunications network utilizes different technological platforms to provide instant connectivity at the higher speeds made possible by our fiber network expansion and wireless network enhancements. Streaming, augmented reality, "smart" technologies, user generated content and artificial intelligence (AI) are expected to continue to drive greater demand for broadband, which we believe will allow us to capitalize on our fiber and 5G deployments. During 2026, we are focused on the core capabilities of our products, our infrastructure and our network. We will also focus on accelerating our fiber expansion, organically and through our pending acquisition of substantially all of Lumen's Mass Markets fiber business. We will continue to deploy low- and mid-band spectrum to improve speed and capacity, including spectrum to be acquired from our pending transactions with EchoStar Corporation (EchoStar) and other spectrum acquisitions. Our concentration is to aggregate the most traffic on the largest, lowest marginal cost, converged network through efficient spectrum deployment and construction of the largest high-capacity broadband solutions in the United States, while also working with regulators and customers to decommission high-cost legacy technologies over the next several years.

*Wireless Service* We continue to experience rapid growth in data usage as consumers are demanding seamless access across their wireless and wired devices, and businesses and municipalities are connecting an increasing number of equipment and facilities to the internet. The deployment of 5G, which allows for faster connectivity, lower latency and greater bandwidth, requires modifications of existing cell sites to add equipment supporting new frequencies, like the C-Band and the 3.45 GHz band. The increased speeds and network operating efficiency expected with 5G technology has enabled massive deployment of devices connected to the internet as well as faster delivery of data services. As the wireless industry has matured, with nearly full penetration of smartphones in the U.S. population, future wireless growth will depend on our ability to offer innovative services, plans and devices that bundle product offerings, add converged customer relationships and take advantage of our 5G wireless network.

To support higher mobile data usage, our priority is to best utilize a wireless network that has sufficient spectrum and capacity to support these innovations on as broad a geographic basis as possible. We expect to continue to invest significant capital in expanding our network capacity, as well as obtaining additional spectrum, when needed and available, that meets our long-term needs. We participate in FCC spectrum auctions, acquire spectrum licenses from third parties as it becomes available and redeploy existing spectrum previously used for more basic services to support more advanced mobile internet services.

In North America, our network covers over 441 million people with 4G LTE and over 322 million with 5G technology. In the United States, our network covers all major metropolitan areas and more than 337 million people with our LTE technology and more than 322 million people with our 5G technology.

*Broadband Technology* Fiber is a core priority for our business and over the last several years we have enhanced our focus to expand our fiber footprint and grow customers. At December 31, 2025, we had 10.4 million fiber consumer wireline broadband customers, adding 1.1 million during the year. The expansion builds on our recent investments to convert to a software-based network, managing the migration of wireline customers to services using our fiber infrastructure to provide broadband technology. Software-based technologies align with our global leadership in software defined network (SDN) and network function virtualization (NFV). This network approach delivers a demonstrable cost advantage in the deployment of next-generation technology over the traditional, hardware-intensive network approach. Our virtualized network supports next-generation applications like 5G and broadband-based services quickly and efficiently. At December 31, 2025, we had 16.0 million broadband connections, compared to 15.3 million broadband connections in the prior year.

In areas where fiber services are not available, in recent years we have offered fixed wireless access under our AT&T Internet Air (AIA) brand. At December 31, 2025, we had 1.5 million AIA connections, adding 875,000 during the year. With recent spectrum acquisitions, including our pending transaction with EchoStar we are expanding the capacity of the wireless network over which these services are provided to support this growth initiative.

*Copper Decommissioning* While building the network of the future, we are actively working to exit our legacy copper network operations across the large majority of our wireline footprint. Our exit strategy includes migrating customers to fiber and wireless alternatives, and working with policy-makers to decommission our inefficient and less reliable copper network. At December 31, 2025, we had 2.1 million customer location switched access lines in service and 2.8 million legacy consumer internet connections compared to 2.7 million customer location switched access lines in service and 4.1 million legacy consumer internet connections in the prior year.

Additional information on our geographical distribution of revenues is contained in Note 4 of Item 8.

**GOVERNMENT REGULATION**

Facilities-based wireless communications providers in the United States, like AT&T, must be licensed by the FCC to provide communications services at specified spectrum frequencies within defined geographic areas and must comply with FCC rules and policies governing the use of the spectrum. The FCC's rules have a direct impact on whether the wireless industry has sufficient spectrum available to support the high-quality, innovative services our customers demand. Wireless licenses are issued for a fixed time period, typically 10 to 15 years, and we must seek renewal of these licenses. While the FCC has generally renewed licenses, the FCC has authority to both revoke a license for cause and to deny a license renewal if a renewal is not in the public interest. Additionally, while wireless communications providers' prices and service offerings have historically not been subject to prescriptive regulation, the federal government and various states periodically consider new regulations and legislation relating to various aspects of wireless services.

The Communications Act of 1934 and other related laws give the FCC authority to regulate the U.S. operations of our interstate telecommunications services. In addition, our ILEC subsidiaries are subject to regulation by state governments, which may regulate intrastate services, provided such state regulation is consistent with federal law. Some states have eliminated or reduced regulations on our retail offerings. AT&T subsidiaries are also subject to the jurisdiction of the FCC with respect to intercarrier compensation, interconnection, and interstate and international services, including interstate access charges. Access charges are a form of intercarrier compensation designed to reimburse our wireline subsidiaries for the use of their networks by other carriers.

We continue to support regulatory and legislative measures and efforts at both the federal and state levels to minimize and/or moderate regulatory burdens that are no longer appropriate in a competitive communications market and that inhibit our ability to compete more effectively and offer services wanted and needed by our customers, including initiatives to transition services from traditional networks to all IP-based networks. At the same time, we also seek to ensure that legacy regulations are not further extended to broadband or wireless services, which are subject to vigorous competition.

Our subsidiaries operating outside the United States are subject to the jurisdiction of national and supranational regulatory authorities in the market where service is provided.

For a discussion of significant regulatory issues directly affecting our operations, please see the information contained under the headings "Operating Environment and Trends of the Business" and "Regulatory Landscape" of Item 7, which information is incorporated herein by reference.

**IMPORTANCE, DURATION AND EFFECT OF LICENSES**

Certain of our subsidiaries own or have licenses to various patents, copyrights, trademarks and other intellectual property necessary to conduct business. Many of our subsidiaries also hold government-issued licenses or franchises to provide wireline or wireless services. Additional information relating to regulations affecting those rights is contained under the heading "Regulatory Landscape" of Item 7. We actively pursue patents, trademarks and service marks to protect our intellectual property within the United States and abroad. We maintain a significant global portfolio of patents, trademarks and service mark registrations. We have also entered into licenses that permit other companies to utilize certain of our patents, trademarks,

------

| **AT&T Inc.** |
| Dollars in millions except per share amounts |

---

service marks, and technologies, in exchange for payments and subject to appropriate safeguards and restrictions. As we transition our network from a switch-based network to an IP, software-based network, we have increasingly entered into licensing agreements with software developers.

We periodically license third-party patents and other intellectual rights in exchange for payments. We also receive claims from third parties asserting that our products, services or technologies infringe on their patents or other intellectual property rights. These claims could require us to pay damages or acquire license rights, stop offering the relevant products or services, and/or cease network functions or other activities. While the outcome of any litigation is uncertain, we do not believe that the resolution of any of these infringement claims or the expiration or non-renewal of any of our intellectual property rights would have a material adverse effect on our results of operations.

**MAJOR CUSTOMERS**

No customer accounted for 10% or more of our consolidated revenues in 2025, 2024 or 2023.

**COMPETITION**

Competition continues to increase for communications and digital services from traditional and nontraditional competitors. Technological advances have expanded the types and uses of services and products available. In addition, lack of or a reduced level of regulation of comparable legacy services has lowered costs for alternative communications service providers. As a result, we face continuing competition as well as some new opportunities in significant portions of our business.

**Wireless** We face substantial competition in our wireless businesses. Under current FCC rules, multiple licensees, who provide wireless services on the cellular, PCS, Advanced Wireless Services, 700 MHz and other spectrum bands, may operate in each of our U.S. service areas. Our competitors include two national wireless providers; a larger number of regional providers and resellers of each of those providers' services; and certain cable companies. In addition, we face competition from providers who offer voice, text messaging and other services as applications on data networks. We are one of three facilities-based providers in Mexico (retail and wholesale), with the most significant market share controlled by América Móvil. We may experience significant competition from companies that provide similar services using other communications technologies and services. While some of these technologies and services are now operational, others are being developed or may be developed. We compete for customers based principally on service/device offerings, price, network quality, coverage area and customer service.

**Broadband** The desire for high-speed data on demand, including data-intensive activities, is continuing to lead customers to terminate their traditional wired or copper-based services and use our fiber or fixed wireless services or competitors' fixed wireless, satellite and internet-based services. In most U.S. markets, we compete for customers with large cable companies and wireless broadband providers for high-speed internet and voice services.

**Legacy Voice and Data** We continue to lose legacy voice and data customers due to industry-wide secular declines and competitors (e.g., wireless, cable and VoIP providers) who can provide comparable services at lower prices because they are not subject to traditional telephone industry regulation (or the extent of regulation they are subject to is in dispute), utilize different technologies or promote a different business model. In most U.S. markets, we compete for customers with large cable companies and other smaller telecommunications companies.

Additionally, we provide local and interstate telephone and switched services to other service providers, primarily large internet service providers using the largest class of nationwide internet networks (internet backbone), wireless carriers, other telephone companies, cable companies and systems integrators. These services are subject to additional competitive pressures from the development of new technologies, the introduction of innovative offerings and increasing satellite, wireless, fiber-optic and cable transmission capacity for services.

**RESEARCH AND DEVELOPMENT**

AT&T scientists and engineers conduct research in a variety of areas, including IP networking, advanced network design and architecture, network and cybersecurity, network operations support systems and data analytics. The majority of the development activities are performed to create new services and to invent tools and systems to manage secure and reliable networks for us and our customers. Research and development expenses were $843 in 2025, $955 in 2024, and $954 in 2023.

**HUMAN CAPITAL**

**Number of Employees** As of December 31, 2025, we employed approximately 133,030 persons.

**Employee Development** We believe our success depends on our employees' success and that all employees must have the skills they need to thrive. We offer training and elective courses that give employees the opportunity to enhance their skills. We also intend to help cultivate the next generation of talent that will lead our company into the future by providing employees with educational opportunities through our internal training organization.

**Labor Contracts** Approximately 43% of our employees are represented by the Communications Workers of America (CWA), the International Brotherhood of Electrical Workers (IBEW) or other unions. After expiration of collective bargaining agreements, work stoppages or labor disruptions may occur in the absence of new contracts or other agreements being reached. The main contracts set to expire in 2026 include the following:

• A contract covering approximately 9,000 employees across 36 states and the District of Columbia is set to expire in February.

• A contract covering approximately 4,300 employees across five states is set to expire in April.

• Two wireline contracts covering approximately 1,800 employees across all 50 states as well as the U.S. Virgin Islands and Puerto Rico are set to expire in April.

**Compensation and Benefits** In addition to salaries, we provide a variety of benefit programs to help meet the needs of our employees. These programs cover active and former employees and may vary by subsidiary and region. These programs include 401(k) plans, pension benefits, and health and welfare benefits, among many others. In addition to our active employee base, at December 31, 2025, we had approximately 477,000 retirees and dependents who were eligible to receive retiree benefits.

We review our benefit plans to maintain competitive packages that reflect the needs of our workforce. We also adapt our compensation model to provide fair and inclusive pay practices across our business. We are committed to pay equity for employees who hold the same jobs, work in the same geographic area, and have the same levels of experience and performance.

**Employee Wellness** We provide our employees access to flexible and convenient health and welfare programs and workplace accommodations. We have prioritized self-care and emphasized a focus on wellness and providing flexible scheduling or time-off options.

**ITEM 1A. RISK FACTORS**

In addition to the other information set forth in this document, including the matters contained under the heading "Cautionary Language Concerning Forward-Looking Statements," you should carefully read the matters described below. We believe that each of these matters could materially affect our business. Most, if not all, of these factors are beyond our ability to control.

**Macro-Economic Factors:**

**Adverse changes in the U.S. securities markets, a higher interest rate environment, rising inflation and medical costs could materially increase our benefit plan costs and future funding requirements.** 

Our costs to provide current benefits and funding for future benefits are subject to increases, primarily due to continuing increases in medical and prescription drug costs, in part due to inflation, and can be affected by lower returns on assets held by our pension and other benefit plans, which are reflected in our financial statements for that year. In calculating the recognized benefit costs, we have made certain assumptions regarding future investment returns, interest rates and medical costs. These assumptions could change significantly over time and could be materially different than originally projected. Lower than assumed investment returns, an increase in our benefit obligations, and higher than assumed medical and prescription drug costs will increase expenses.

The Financial Accounting Standards Board (FASB) requires companies to recognize the funded status of defined benefit pension and postretirement plans as an asset or liability in their statement of financial position and to recognize changes in that funded status in the year in which the changes occur. We have elected to reflect the annual adjustments to the funded status in our consolidated statement of income. Therefore, an increase in our costs or adverse market conditions will have a negative effect on our operating results.

Significant adverse changes in capital markets could result in the deterioration of our defined benefit plans' funded status.

**Inflationary pressures on costs, such as inputs for devices we sell and network components, labor and distribution costs, may impact our network construction, our financial condition or results of operations.**

As a provider of telecommunications and technology services, we sell handsets, wireless data cards, wireless computing devices and customer premises equipment manufactured by various suppliers for use with our voice and data services and depend on suppliers to provide us, directly or through other suppliers, with items such as network equipment, customer premises equipment, and wireless-related equipment such as mobile hotspots, handsets, wirelessly enabled computers, wireless data cards and other connected devices for our customers. In recent years, the costs of these inputs and the costs of labor necessary to develop, deploy and maintain our networks and our products and services have increased. In addition, many of these inputs are subject to price fluctuations from a number of factors, including, but not limited to, market conditions, demand for raw

------

| |
|:---|
| **AT&T Inc.** |
| Dollars in millions except per share amounts |

---

materials used in the production of these devices and network components, severe weather, energy costs, currency fluctuations, supplier capacities, governmental actions, import and export requirements (including tariffs), and other factors beyond our control. Recent spending by hyperscalers and others to support AI is beginning to pressure supply chains for goods such as semiconductors and other network components. Inflationary and supply pressures may continue into the future and could have an adverse impact on our ability to source materials.

Our attempts to offset these cost and supply pressures, such as through increases in the selling prices of some of our products and services, may not be successful. Higher product or service prices may result in reductions in sales volume or increases in subscriber churn. Consumers may be less willing to pay a price differential for our products and services and may increasingly purchase lower-priced offerings from us or our competitors, or may forego some purchases altogether, during a period of inflationary pressure or an economic downturn. To the extent that price increases are not sufficient to offset these increased costs adequately or in a timely manner, and/or if they result in significant decreases in sales volume, our business, financial condition or operating results may be adversely affected. Furthermore, we may not be able to offset any cost increases through productivity and cost-saving initiatives.

**Adverse changes in global financial markets could limit our ability and our larger customers' and suppliers' ability to access capital or increase the cost of capital needed to fund business operations.**

In recent years, uncertainty surrounding global growth rates, inflation and the interest rate environment produced volatility in the credit, currency and equity markets. Volatility may affect companies' access to the credit markets, leading to higher borrowing costs, or, in some cases, the inability to fund ongoing operations. In addition, we contract with large financial institutions to support our own treasury operations, including contracts to hedge our exposure to interest rates and foreign exchange and the funding of credit lines and other short-term debt obligations, including commercial paper. These financial institutions face stricter capital-related and other regulations in the United States and Europe, as well as ongoing legal and financial issues concerning their loan portfolios, which may hamper their ability to provide credit or raise the cost of providing such credit.

While we have been successful in continuing to access the credit and fixed income markets when needed, adverse changes in the financial markets could render us either unable to access these markets or able to access these markets only at higher interest costs and with restrictive financial or other conditions, severely affecting our business operations. Additionally, downgrades of our credit rating by the major credit rating agencies could increase our cost of borrowing and also impact the collateral we would be required to post under certain agreements we have entered into with our derivative counterparties, which could negatively impact our liquidity. Further, valuation changes in our derivative portfolio due to interest rates and foreign exchange rates could require us to post collateral and thus may negatively impact our liquidity.

**Our international operations increase our exposure to political instability, to changes in the international economy and to regulation on our business, and these risks could offset our expected growth opportunities.**

We have international operations, particularly in Mexico, and other countries worldwide where we need to comply with a wide variety of complex local laws, regulations and treaties, and are subject to evolving political environments. In addition, we are exposed to, among other factors, fluctuations in currency values, changes in relationships between U.S. and foreign governments, war or other hostilities, and other regulations that may materially affect our earnings. Involvement with foreign firms also exposes us to the risk of being unable to control the actions of those firms and therefore exposes us to risks associated with our obligation to comply with the Foreign Corrupt Practices Act (FCPA). Violations of the FCPA could have a material adverse effect on our operating results.

**Industry-Wide Factors:**

**Changes to federal, state and foreign government regulations and decisions in regulatory proceedings, as well as private litigation, could further increase our operating costs and/or alter customer perceptions of our operations, which could materially adversely affect us.**

Our subsidiaries providing wired services are subject to significant federal and state regulation, while many of our competitors are not. In addition, our subsidiaries and affiliates operating outside the United States are also subject to the jurisdiction of national and supranational regulatory authorities in the markets where service is provided. Our wireless subsidiaries are regulated to varying degrees by the FCC and in some instances, by state and local agencies. Adverse regulations and rulings by the courts, the FCC or states relating to broadband and wireless deployment could impede our ability to manage our networks and recover costs and lessen incentives to invest in our networks. The continuing growth of IP-based services, especially when accessed by wireless devices, has created or potentially could create conflicting regulation between the FCC and various state and local authorities, which may involve lengthy litigation to resolve and may result in outcomes unfavorable to us. In addition, increased public focus on a variety of issues related to our operations, such as privacy issues, government requests or orders for customer data, state rate regulation of broadband and concerns about global climate change, have led to proposals or new

------

---

| |
|:---|
| **AT&T Inc.** |
| Dollars in millions except per share amounts |

---

legislation at state, federal and foreign government levels to change or increase regulation on our operations, which could result in additional costs of compliance or litigation. Enactment of new privacy laws and regulations could, among other things, adversely affect our ability to collect data and offer targeted advertisements or result in additional costs of compliance or litigation. Should customers decide that our competitors offer a more customer-friendly environment, our competitive position, results of operations or financial condition could be materially adversely affected.

**Extreme weather events and other potential effects of climate change may impose risk of damage to our infrastructure, our ability to provide services, and may cause changes in federal, state and foreign government regulation, all of which may result in potential adverse impact to our financial results.**

The potential physical effects of extreme weather events and other potential effects of climate change, such as increased frequency and severity of storms, floods, fires, freezing conditions, sea-level rise and other climate-related events, could damage our networks and cause disruptions in our services, which could adversely affect our operations, infrastructure and financial results. Operational impacts resulting from the potential physical effects of climate change, such as damage to our network infrastructure, could result in increased costs and loss of revenue. While we currently do not believe the potential losses or costs associated with the physical effects of climate change will be material, it is difficult to accurately and precisely calculate the future impacts of the physical effects of climate change given the dynamic nature of its impacts on the environment.

**Continuing growth in and the converging nature of wireless and broadband services will require us to deploy significant amounts of capital and require ongoing access to spectrum in order to provide attractive services to customers.**

Wireless and broadband services are undergoing rapid and significant technological changes and a dramatic increase in usage, including, in particular, the demand for faster and seamless usage of data across mobile and fixed devices. Recent world events and trends accelerated these changes and also resulted in higher network utilization, as more customers consumed bandwidth. Streaming, augmented reality, "smart" technologies, user generated content and AI are expected to continue to drive greater demand for broadband. We must continually invest in our networks in order to improve our wireless and broadband services to meet this increasing demand and changes in customer expectations while remaining competitive. Improvements in these services depend on many factors, including continued access to and deployment of adequate spectrum and the capital needed to expand our wireline network to support transport of these services. In order to stem broadband connectivity losses to cable competitors in our non-fiber wireline areas, we have been expanding our all-fiber wireline network and where we offer our fixed wireless access product. We must maintain and expand our network capacity and coverage for transport of data, including video, and voice between cell and fixed landline sites. To this end, we participate in spectrum auctions and continue to deploy software and other technology advancements in order to efficiently invest in our network.

We have spent, and plan to continue spending, significant capital and other resources on the ongoing development and deployment of our 5G and fiber networks. This deployment and other network service enhancements and product launches may not occur as scheduled or at the cost expected due to many factors, including unexpected inflation, delays in determining equipment and wireless handset operating standards, supplier delays, software issues, increases in network and handset component costs, regulatory permitting delays for tower sites or enhancements, or labor-related delays. Deployment of new technology also may adversely affect the performance of the network for existing services. If we cannot acquire needed spectrum, if our 5G and fiber standalone or converged offerings fail to gain acceptance in the marketplace or if we otherwise fail to deploy the services customers desire on a timely basis with acceptable quality and at reasonable costs, then our ability to attract and retain customers, and, therefore, maintain and improve our operating margins, could be materially adversely affected.

**Increasing competition could materially adversely affect our operating results.**

We have multiple wireless competitors in each of our service areas and compete for customers based principally on service/device offerings, price, network quality, reliability, speed, coverage area and customer service. In addition, we are facing growing competition from providers offering services using advanced wireless technologies and IP-based networks, among others. We expect market saturation to continue, which may cause the wireless industry's customer growth rate to moderate in comparison with historical growth rates, leading to increased competition for customers, including from strategic alliances in converged connectivity. Our share of industry sales could be reduced due to aggressive pricing or promotional strategies pursued by competitors. We also expect that our customers' growing demand for high-speed video and data services will place constraints on our network capacity. These competition and capacity constraints will continue to put pressure on pricing and margins as companies compete for potential customers. Additionally, we may not be able to accurately predict future consumer demands or the success of new services in markets. Our ability to address these issues will depend, among other things, on continued improvement in network quality and customer service and our ability to price our products and services competitively as well as effective marketing of attractive products and services. These efforts will involve significant expenses and require strategic management decisions on, and timely implementation of, equipment choices, network deployment and service offerings. In addition, a sustained decline in a reporting unit's revenues and earnings has resulted in the past, and may

again result in the future, in a significant negative impact on its fair value, requiring us to record an impairment charge, which could have an adverse impact on our results of operations.

**Intellectual property rights may be inadequate to take advantage of business opportunities, which may materially adversely affect our operations.** 

We may need to spend significant amounts of money to protect our intellectual property rights. Any impairment of our intellectual property rights, including due to changes in U.S. or foreign intellectual property laws or the absence of effective legal protections or enforcement measures, could materially adversely impact our operations.

**Incidents or public assertions leading to damage to our reputation or questions about our business conduct, and any resulting lawsuits, claims or other legal proceedings, could have a material adverse effect on our business.**

We believe that our brand image, awareness and reputation strengthen our relationship with consumers and contribute significantly to the success of our business. Our reputation and brand image could be negatively affected by a number of factors, including the safety, quality or reliability of our services, products and operations; cybersecurity incidents and data breaches, including our actual or perceived responses thereto; regulatory compliance; governance issues; our actual or perceived position or lack of position on social and other sensitive matters; and the conduct of our employees and former employees. Our ability to attract and retain employees is highly dependent upon our commitment to an inclusive workplace, ethical business practices and other qualities.

We currently are, and may in the future be, named as a defendant in lawsuits, claims and other legal proceedings that arise in or outside the ordinary course of our business based on alleged acts of misconduct by employees, contractors or other third parties. These actions seek, among other things, compensation for alleged personal injury (including claims for loss of life), workers' compensation, employment discrimination, sexual harassment, workplace misconduct, wage and hour claims and other employment-related damages, compensation for breach of contract, statutory or regulatory claims, negligence or gross negligence, punitive damages, consequential damages, and civil penalties or other losses or injunctive or declaratory relief. The outcome of any allegations, lawsuits, claims or legal proceedings is inherently uncertain and could result in significant costs, damage to our brands or reputation and diversion of management's attention from our business. In 2023, *The Wall Street Journal* published a series of articles alleging that lead-clad telecommunications cables are a public health hazard or may pose environmental risks. We are currently subject to litigation and have received inquiries from government authorities as a result of these assertions. We may be subject to additional litigation, government investigations and potentially new regulation or legislation relating to lead-clad cables. Any damage to our reputation or payments of significant amounts as a result of any of these issues, even if reserved, could materially and adversely affect our business, ability to serve customers, reputation, financial condition, results of operations and cash flows.

**Our business is subject to risks related to public health crises.**

Public health crises and resulting mitigation measures have in the past, and may in the future, cause a negative effect on our operating results. These effects include, but are not limited to, closure of retail stores; impact on our customers' ability to pay for our products and services; reduction in international roaming revenue; and reduced staffing levels in call centers and field operations. We also have in the past, and may in the future, incur significantly higher expenses attributable to infrastructure investments and increased labor costs due to public health crises.

**Company-Specific Financial Factors:**

**Customer adoption of new software-based technologies may require higher-quality services from us, and meeting these demands could create supply chain issues and could increase capital costs.** 

The communications industry has experienced rapid changes in the past several years. An increasing number of our customers are using mobile devices for using AI-enabled applications and as their primary means of viewing video. In addition, businesses and government bodies are broadly shifting to wireless-based services for homes and infrastructure to improve services to their respective customers and constituencies. We have spent, and continue to spend, significant capital to shift our wired network to software-based technology and are expanding 5G wireless technology to address these demands. We have entered and continue to enter into a significant number of software licensing agreements and continue to work with software developers to provide network functions in lieu of installing switches or other physical network equipment in order to respond to rapid developments in wireless demand. While software-based functionality can be changed much more quickly than, for example, physical switches, the rapid pace of development means that we may increasingly need to rely on single-source and software solutions that have not previously been deployed in production environments. Should this software not function as intended or our license agreements provide inadequate protection from intellectual property infringement claims, we could be forced to either substitute (if available) or else spend time to develop alternative technologies at a much higher cost and incur harm to our reputation for reliability, and, as a result, our ability to remain competitive could be materially adversely affected.

**We depend on various suppliers to provide equipment to operate our business and satisfy customer demand, and interruption or delay in supply can adversely impact our operating results.**

We depend on suppliers to provide us, directly or through other suppliers, with items such as network equipment, customer premises equipment and wireless-related equipment such as mobile hotspots, handsets, wirelessly enabled computers, wireless data cards and other connected devices for our customers. In some instances, we depend on key single-source suppliers to provide important inputs where there are few alternative suppliers available. These suppliers could fail to provide equipment on a timely or cost-effective basis, or fail to meet our performance expectations, for a number of reasons, including difficulties in obtaining export licenses for certain technologies, inflationary pressures, inability to secure component parts, general business disruption, natural disasters, safety issues, economic and political instability, including the outbreak of war and other hostilities, and public health emergencies. In certain circumstances, we could be liable for the actions of our suppliers and other third parties we do business with. These factors have caused, and may again cause, delays in the development, manufacturing (including the sourcing of key components) and shipment of products to the extent that we or our suppliers are impacted. In certain limited circumstances, suppliers have been unable to supply products in a timely fashion, affecting our ability to provide products and services precisely as and when requested by our customers. It is possible that, in some circumstances, we could be forced to switch to a different key supplier or be unable to meet customer demand for certain products or services. Because of the cost and time lag that can be associated with transitioning from one supplier to another, our business could be substantially disrupted if we were required to, or chose to, replace the products of one or more key suppliers with products from another source, especially if the replacement became necessary on short notice. Any such disruption could increase our costs, decrease our operating efficiencies and have a negative effect on our operating results.

**Increasing costs to provide services and failure to renew agreements on favorable terms, or at all, could adversely affect operating margins.**

Our operating costs, including customer acquisition and retention costs, could continue to put pressure on margins and customer retention levels.

A number of our competitors offering comparable legacy services that rely on alternative technologies and business models are typically subject to less regulation, and therefore are able to operate with lower costs. These competitors generally can focus on discrete customer segments since they do not have regulatory obligations to provide universal service. Also, these competitors have cost advantages compared to us, due in part to operating on newer, more technically advanced and lower-cost networks with a nonunionized workforce, lower employee benefits and fewer retirees. We are transitioning services from our copper-based network and seeking regulatory approvals, where needed, at both the state and federal levels. If we do not obtain regulatory approvals for our network transition or obtain approvals with onerous conditions, we could experience significant cost and competitive disadvantages.

**A significant portion of our workforce is represented by labor unions, and we could incur additional costs or experience work stoppages as a result of the renegotiation of our labor contracts.**

As of December 31, 2025, approximately 43% of our workforce was represented by the Communications Workers of America (CWA), the International Brotherhood of Electrical Workers (IBEW) or other unions. While we have labor contracts in place with these unions, with subsequent negotiations we have in the past and could in the future incur additional costs and/or experience work stoppages, which could adversely affect our business operations.

**We may not realize or sustain the expected benefits from acquisitions, joint ventures or our business transformation initiatives, including dispositions, which could have a material adverse effect on our business, operations, financial condition, results of operations and competitive position.**

We have been and will be undertaking certain transformation initiatives and investments, which are designed to reduce costs, enable legacy rationalization, streamline and modernize distribution and customer service, improve our products and services, remove redundancies and simplify and improve processes and support functions. Our focus is on supporting added customer value with an improved customer experience. We intend for these efficiencies to enable increased investments in our strategic areas of focus, which include improving broadband connectivity (for example, fiber and 5G). We also expect these initiatives to drive efficiencies and improved margins. If we do not successfully manage and timely execute these initiatives and investments, which may include acquisitions, joint ventures, particularly those aimed at enhancing our fiber serviceable locations, and other strategic transactions, or if they are inadequate or ineffective, we may fail to meet our financial goals and achieve anticipated benefits, improvements may be delayed, not sustained or not realized, and our business, operations and competitive position could be adversely affected. In addition, any such initiative or investment entails certain risks and could present financial, managerial and operational challenges. Further, we are using and intend to further use AI-driven efficiencies in our network design and operations, software development, sales, marketing, customer support services and general and administrative costs. The models used in those products or operations, particularly generative AI models, may produce output or take action that is incorrect, release private or confidential information, reflect biases included in the data on which they are trained, infringe on the intellectual property rights of others, or be otherwise harmful. AI-related laws and regulations continue to remain uncertain and may vary from jurisdiction to jurisdiction. There can be no assurance that the usage of AI will meaningfully enhance our

------

---

products or operations, and any of these risks could expose us to liability or adverse legal or regulatory consequences and harm our reputation and the public perception of our business or the effectiveness of our security measures.

**Unfavorable litigation or governmental investigation results could require us to pay significant amounts or lead to onerous operating procedures.**

We are subject to a number of lawsuits both in the United States and in foreign countries, including, at any particular time, claims relating to antitrust, patent infringement, wage and hour, personal injury, environmental, customer data and privacy violations, cyberattacks, regulatory proceedings, breach of contract, and selling and collection practices. We also spend substantial resources complying with various government standards, which may entail related investigations and litigation. In the wireless and wireline area, we also face current and potential litigation relating to alleged adverse health effects on customers or employees who use such technologies including, for example, wireless devices. We may incur significant expenses defending such suits or government charges and may be subject to injunctions or required to pay amounts or otherwise change our operations in ways that could materially adversely affect our operations or financial results.

**Cyberattacks impacting our networks, systems or data or those of our suppliers or vendors may have a material adverse effect on our operations or results of operations.**

Cyberattacks – including through the use of malware, computer viruses, distributed denial of services attacks, ransomware attacks, credential harvesting, social engineering and other means for obtaining unauthorized access to or disrupting the operation of our networks and systems or accessing our data and those of our suppliers, vendors and other service providers – could have a material adverse effect on our operations or results of operations. As a critical infrastructure service provider, we believe that we are a particularly attractive target for such cyberattacks, including from nation states and highly sophisticated, state-sponsored, or otherwise well-funded actors, and we experience heightened risk from time to time as a result of geopolitical events.

Cyberattacks have caused, and may in the future cause, equipment or network failures, copying or loss of information, including sensitive personal information of customers or employees or proprietary information, as well as disruptions to our or our customers', suppliers' or vendors' operations, which have and in the future could result in significant expenses, potential investigations and legal liability, a loss of current or future customers and reputational damage. Additional resources and management attention may be necessary to respond to government inquiries and requirements, including potentially conflicting demands and requirements from multiple government agencies. Moreover, the amount and scope of insurance that we maintain against losses resulting from any such events or security breaches may not be sufficient to cover our losses or otherwise adequately compensate us for any disruptions to our business that may result. As our networks evolve, they are becoming increasingly reliant on software and cloud technologies to handle growing demands for data consumption. Cyberattacks against us and our suppliers and vendors have occurred in the past, including from highly sophisticated, state-sponsored actors as noted above, and will continue to occur in the future and are increasing in frequency, scope and potential harm over time. For example, in July 2024, we disclosed a cybersecurity incident on Item 1.05 of Form 8-K relating to the copying of mobile customer call data.

Due to the complexity and interconnectedness of our systems and those of our suppliers, vendors and other service providers, the process of enhancing our protective measures can itself create a risk of systems disruptions and security issues. Further, the use of artificial intelligence and machine learning by cybercriminals may increase the frequency and severity of cybersecurity attacks against us or our suppliers, vendors and other service providers. In addition, despite our efforts to detect unlawful intrusions, an attack may persist for an extended period of time before being detected, and, following detection, it may take considerable time for us to obtain sufficient information about the nature, scope and timing of the incident as well as the impact or reasonably likely impact on us. Indeed, as cyberattacks become increasingly sophisticated, a post-attack investigation may not be able to ascertain the entire scope of the attack's impact.

Extensive and costly efforts are undertaken to develop and test systems before deployment and to conduct ongoing monitoring and updating to prevent and withstand such attacks. While we may have contractual rights to assess the effectiveness of many of our suppliers' and vendors' systems and protocols, we cannot know or assess the effectiveness of all of our providers' systems and controls at all times. While, to date, we have not been subject to a cyberattack that has had a material adverse effect on our operations or results of operations, the preventive actions we take, or our suppliers or vendors take, to reduce the risks associated with cyberattacks may be insufficient to repel or mitigate the effects of a major cyberattack in the future.

**Natural disasters, extreme weather conditions or terrorist or other hostile acts could cause damage to our infrastructure and result in significant disruptions to our operations.**

Our business operations could be subject to interruption by equipment or network failures caused by human error, system failures, unauthorized access to our network and critical infrastructure, power outages, terrorist or other hostile acts, including acts of war, and natural disasters, such as flooding, hurricanes and forest fires. Such events could cause significant damage to the infrastructure upon which our business operations rely, resulting in degradation or disruption of service to our customers, as well as significant recovery time and expenditures to resume operations. Our system redundancy and other measures we take to

------

---

protect our infrastructure and operations from the impacts of such events may be ineffective or inadequate to sustain our operations through all such events. Any of these occurrences could result in lost revenues from business interruption, damage to our reputation and reduced profits.

**Increases in our debt levels to fund spectrum purchases, or other strategic decisions could adversely affect our ability to finance future debt at attractive rates and reduce our ability to respond to competition and adverse economic trends.**

We intend to and have incurred debt to fund significant acquisitions, as well as spectrum purchases needed to compete in our industry. While we believe such decisions were prudent and necessary to take advantage of both growth opportunities and respond to industry developments, we did experience credit rating downgrades from historical levels. Banks and potential purchasers of our publicly traded debt may decide that these strategic decisions and similar actions we may take in the future, as well as expected trends in the industry, will continue to increase the risk of investing in our debt and may demand a higher rate of interest, impose restrictive covenants or otherwise limit the amount of potential borrowing. Additionally, our capital allocation plan is focused on, among other things, managing our debt level. Any failure to successfully execute this plan could adversely affect our cost of funds, liquidity, competitive position and access to capital markets.

**Our business may be impacted by changes in tax laws and regulations, judicial interpretations of the same or administrative actions by federal, state, local and foreign taxing authorities.**

Tax laws are dynamic and subject to change as new laws are passed and new interpretations of the law are issued or applied. In many cases, the application of existing, newly enacted or amended tax laws may be uncertain and subject to differing interpretations, especially when evaluated against ever-changing products and services provided by our global telecommunications and technology businesses. In addition, tax legislation has been introduced or is being considered in various jurisdictions that could significantly impact our tax rate, tax liabilities and carrying value of deferred tax assets or deferred tax liabilities. Any of these changes could materially impact our financial performance and our tax provision, net income and cash flows.

We are also subject to ongoing examinations by taxing authorities in various jurisdictions. Although we regularly assess the likelihood of an adverse outcome resulting from these examinations to determine the adequacy of provisions for taxes, there can be no assurance as to the outcome of these examinations. In the event that we have not accurately or fully described, disclosed or determined, calculated or remitted amounts that were due to taxing authorities or if the ultimate determination of our taxes owed is for an amount in excess of amounts previously accrued, we could be subject to additional taxes, penalties and interest, which could materially impact our business, financial condition and operating results.

**ITEM 1B. UNRESOLVED STAFF COMMENTS**

Not applicable.

**ITEM 1C. CYBERSECURITY**

**Governance**

**Board and Audit Committee Oversight**

Our Board of Directors has delegated to the Audit Committee the oversight responsibility to review and discuss with management the Company's privacy and data security, including cybersecurity, risk exposures, policies and practices, and the steps management has taken to detect, monitor and control such risks and the potential impact of those exposures on our business, financial results, operations and reputation. The full Board and Audit Committee regularly receive reports and presentations on privacy and data security, which address relevant cybersecurity issues and risks and span a wide range of topics. These reports and presentations are provided by officers with responsibility for privacy and data security, who include our Chief Information Security Officer (CISO), Chief Technology Officer (CTO) and AT&T's Legal team. In addition to regular reports to the Audit Committee, we have protocols by which certain security incidents are escalated within the Company and, where appropriate, reported in a timely manner to the Audit Committee.

**Chief Security Office/CISO**

We maintain a Chief Security Office (CSO), which is charged with management-level responsibility for all aspects of network and information security within the Company. Led by our CISO and comprised of a large team of highly trained security professionals across multiple countries, the CSO is responsible for:

&nbsp;&nbsp;&nbsp;&nbsp;a.establishing the policies, standards and requirements for the security of AT&T's computing and network environments;

&nbsp;&nbsp;&nbsp;&nbsp;b.protecting AT&T-owned and -managed assets and resources against unauthorized access by monitoring potential security threats, correlating network events and overseeing the execution of corrective actions;

&nbsp;&nbsp;&nbsp;&nbsp;c.promoting compliance with AT&T's security policies and network and information security program in a consistent manner on network systems and applications; and

&nbsp;&nbsp;&nbsp;&nbsp;d.providing security thought leadership in the global security arena.

Our CISO plays the key management role in assessing and managing our material risks from cybersecurity threats. The CISO also works closely with AT&T Legal to oversee compliance with legal, regulatory and contractual security requirements. The CISO has extensive technical leadership experience and cybersecurity expertise, gained from over 20 years of experience, including serving as the Chief Information Security Officer and Director of the Office of Cybersecurity at a U.S. government agency, in addition to serving as the Chief Information Security Officer of two large public companies. Prior to that, he served for 20 years in the U.S. military, in various information technology roles of increasing seniority. The security professionals in the CSO have cybersecurity backgrounds and expertise relevant to their roles, including, in certain circumstances, relevant industry certifications.

**Risk Management and Strategy**

We maintain a network and information security program that is reasonably designed to protect our information, and that of our customers, from unauthorized risks to their confidentiality, integrity or availability. Our program encompasses the CSO and its policies, platforms, procedures and processes for assessing, identifying and managing risks from cybersecurity threats, including third-party risk from vendors and suppliers. The program is integrated into our overall risk management framework and is generally designed to identify and respond to security incidents and threats in a timely manner to minimize the loss or compromise of information assets and to facilitate incident resolution.

We maintain continuous and near-real-time security monitoring of the AT&T network for investigation, action and response to network security events. This security monitoring leverages tools, where available, such as near-real-time data correlation, situational awareness reporting, active incident investigation, case management, trend analysis and predictive security alerting. We assess, identify and manage risks from cybersecurity threats through various mechanisms, which from time to time may include tabletop exercises to test our preparedness and incident response process, business unit assessments, control gap analyses, threat modeling, impact analyses, internal audits, external audits, penetration tests and engaging third parties to conduct analyses of our information security program. When circumstances warrant, we also retain external cybersecurity experts to assist the CSO. We conduct vulnerability testing and assess identified vulnerabilities for severity, the potential impact to AT&T and our customers, and likelihood of occurrence. We regularly evaluate security controls to maintain their functionality in accordance with security policy. We also obtain cybersecurity threat intelligence from recognized forums, third parties and other sources as part of our risk assessment process. In addition, as a critical infrastructure entity, we collaborate

------

| **AT&T Inc.** |
| Dollars in millions except per share amounts |

---

with numerous agencies in the U.S. government to help protect U.S. communications networks and critical infrastructure, which, in turn, informs our cybersecurity threat intelligence.

With respect to incident response, the Company has adopted a Cybersecurity Incident Response Plan, as well as a Data Privacy Incident Response Plan that applies if customer information has been compromised (together, the "IRPs"), to provide a common framework for responding to security incidents. This framework establishes procedures for identifying, validating, categorizing, documenting and responding to security events that are identified by or reported to the CSO. The IRPs apply to all AT&T personnel (including contractors and partners) that perform functions or services that require securing AT&T information and computing assets, and to all devices and network services that are owned or managed by the Company.

The IRPs set out a coordinated, multi-functional approach for investigating, containing and mitigating incidents, including reporting findings to senior management and other key stakeholders and keeping them informed and involved as appropriate. In general, our incident response process follows the NIST (National Institute of Standards and Technology) framework and focuses on four phases: preparation; detection and analysis; containment, eradication and recovery; and post-incident remediation.

**Impact of Cybersecurity Risk**

In 2025, we did not identify and were not aware of any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that we believe have materially affected or are reasonably likely to materially affect our business strategy, results of operations or financial condition. For a discussion of cybersecurity risk, please see the information contained under the heading "Cyberattacks impacting our networks, systems or data or those of our suppliers or vendors may have a material adverse effect on our operations or results of operations" of Item 1A.

**ITEM 2. PROPERTIES**

Our properties do not lend themselves to description by character and location of principal units. At December 31, 2025, of our total property, plant and equipment, outside plant (including cable, wiring and other non-central office network equipment) represented 29%; other equipment, comprised principally of wireless network equipment attached to towers, furniture and office equipment and vehicles and other work equipment, represented 26%; central office equipment represented 25%; land, building and wireless communications towers represented 12%; and other miscellaneous property represented 8%.

For our Communications segment, substantially all of the installations of central office equipment are located in buildings and on land we own. Many garages, administrative and business offices, wireless towers, telephone centers and retail stores are leased. Property on which communications towers are located may be either owned or leased.

**ITEM 3. LEGAL PROCEEDINGS**

We are a party to numerous lawsuits, regulatory proceedings and other matters arising in the ordinary course of business. As of the date of this report, we do not believe any pending legal proceedings to which we or our subsidiaries are subject are required to be disclosed as material legal proceedings pursuant to this item.

**ITEM 4. MINE SAFETY DISCLOSURES**

**ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

**OVERVIEW**

AT&T Inc. is referred to as "we," "AT&T" or the "Company" throughout this document. AT&T products and services are provided or offered by subsidiaries and affiliates of AT&T Inc. under the AT&T brand and not by AT&T Inc., and the names of the particular subsidiaries and affiliates providing the services generally have been omitted. AT&T is a holding company whose subsidiaries and affiliates operate worldwide in the telecommunications and technology industries. You should read this discussion in conjunction with the consolidated financial statements and accompanying notes (Notes).

Our Management's Discussion and Analysis of Financial Condition and Results of Operations included in this document generally discusses 2025 and 2024 items and year-to-year comparisons between 2025 and 2024. Discussions of 2023 items and year-to-year comparisons between 2024 and 2023 that are not included in this document can be found in "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II, Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

We have two reportable segments: Communications and Latin America. Our segment results presented in Note 4 and discussed below follow our internal management reporting. Each segment's percentage calculation of total segment operating revenue is derived from our segment results table in Note 4. Segment operating income is primarily attributable to our Communications segment due to prior-years operating losses in Latin America. Percentage increases and decreases that are not considered meaningful are denoted with a dash.

**OVERVIEW**

**Operating revenues** increased in 2025, reflecting higher Mobility and Consumer Wireline revenues, partially offset by declines in Business Wireline. Operating revenues in Mexico were also higher, overcoming unfavorable foreign exchange impacts during the first half of 2025.

**Operations and support expenses** increased in 2025, reflecting higher sales volumes in our Mobility business unit, which drove higher equipment, advertising, selling and bad debt expenses. Also contributing to higher costs were approximately $440 of apportioned legal settlements during 2025, higher network-related expenses and advertising costs due to the launch of a new campaign in 2025. Increases were partially offset by declines from our continued transformation efforts and lower content licensing fees.

**Asset impairments and abandonments and restructuring** decreased in 2025, with higher impairments in 2024. Noncash charges in 2024 primarily related to a goodwill impairment charge of $4,422 associated with our Business Wireline reporting unit as well as restructuring charges, including termination fees associated with our network modernization program to deploy commercial scale open radio access network (Open RAN). Expenses in 2025 primarily relate to restructuring severance charges.

**Depreciation and amortization** expense increased in 2025, primarily due to ongoing capital spending for strategic initiatives such as fiber and network upgrades, partially offset by lower depreciation from fully depreciated legacy assets and impacts from our Open RAN network modernization efforts.

**Operating income** increased in 2025 and decreased in 2024. Our operating margin was 19.2% in 2025, compared to 15.6% in 2024, and 19.2% in 2023.

**Interest expense** increased in 2025, primarily due to lower capitalized interest associated with spectrum acquisitions. The increase was partially offset by lower average commercial paper balances.

**Equity in net income of affiliates** decreased in 2025, reflecting our sale of DIRECTV in July 2025. The decrease was partially offset by cash distributions received by AT&T in excess of the carrying amount of our investment in DIRECTV prior to disposition (see Notes 10 and 19).

**Other income (expense) – net** increased in 2025. The increase was primarily due to a gain of approximately $5,600 recognized on the sale of our interest in DIRECTV (see Note 10). The increase was also driven by a gain on a prior disposition and noncash impairment charges for a held-for-sale business and our SKY Mexico equity investment. Partially offsetting the increases were lower pension and postretirement benefit credits and lower returns on other benefit-related investments.

**Income tax expense** decreased in 2025, primarily due to a lower effective tax rate driven by a tax-free gain on sale of DIRECTV in 2025 and a goodwill impairment in 2024, which is not deductible for tax purposes.

Our effective tax rate was 13.4% in 2025, 26.6% in 2024, and 21.3% in 2023, reflecting the nonrecognition of income taxes on the DIRECTV gain and larger discrete tax benefits in 2025, and the goodwill impairment in 2024, which was not deductible for tax purposes.

**Segment Results** 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 evaluate segment performance based on operating income as well as EBITDA and/or EBITDA margin. See "Discussion and Reconciliation of Non-GAAP Measures" for a reconciliation of EBITDA and EBITDA margin to the most comparable financial measures calculated and presented in accordance with U.S. generally accepted accounting principles (GAAP).

**Operating revenues** increased in 2025, driven by increases in Mobility service revenue and our Consumer Wireline business unit, driven by gains in wireless and broadband services. Partially offsetting these increases were declines in our Business Wireline business unit, which reflects lower demand for legacy services.

**Operating income** increased in 2025 and decreased in 2024. The 2025 operating income reflects an increase in operating income from our Mobility and Consumer Wireline business units, partially offset by a decrease in our Business Wireline business unit. Our Communications segment operating income margin was 23.1% in 2025, 23.0% in 2024 and 23.6% in 2023. Our Communications segment EBITDA margin was 39.6% in 2025, 39.5% in 2024 and 38.3% in 2023.

**Service** revenue increased during 2025, largely due to growth from subscriber gains, partially offset by promotional activity.

*ARPU*

Postpaid ARPU increased in 2025 reflecting pricing actions that were largely offset by increased promotional activity, growth in our converged customer relationships, and our success in attracting customers in underpenetrated segments with lower ARPUs but attractive lifetime values, such as age 55-plus in our "value customers."

*Churn*

The effective management of subscriber churn is critical to our ability to maximize revenue growth and to maintain and improve margins. Postpaid churn and postpaid phone churn were higher in 2025, partially driven by an increase in our customer base that reached the end of device financing periods, which normalized in the second half of 2025.

**Equipment** revenue increased in 2025, primarily driven by higher wireless device sales volumes.

**Operations and support** expenses increased in 2025, primarily due to higher sales volumes, which drove higher equipment, advertising, selling and bad debt expenses. The increase also reflected higher advertising due to the launch of a new campaign, and higher network costs that were partially offset by lower content licensing fees and expense declines from transformation efforts.

**Depreciation** expense increased in 2025, primarily due to ongoing capital spending for network upgrades and expansion, partially offset by lower depreciation impacts from our network modernization efforts.

**Operating income** increased in 2025 and 2024. Our Mobility operating income margin was 30.4% in 2025, 30.9% in 2024 and 30.8% in 2023. Our Mobility EBITDA margin was 42.0% in 2025, 42.8% in 2024 and 40.9% in 2023.

**Legacy and other transitional services** revenues decreased in 2025, driven by lower demand for legacy and VPN services, which we expect to continue as we decommission our copper-based legacy network. These revenue declines were partially offset by targeted pricing actions in the first quarter of 2025.

**Fiber and advanced connectivity services** revenues increased in 2025, driven by higher fiber and fixed wireless revenues.

**Equipment** revenues decreased in 2025, driven by lower customer premises equipment sales, which can vary from year to year based on the nature of services purchased.

**Operations and support** expenses decreased in 2025, primarily driven by lower personnel and customer support costs associated with ongoing transformation initiatives. Expense declines also include lower network and advertising costs.

**Depreciation** expense increased in 2025, primarily due to ongoing capital investment for strategic initiatives such as fiber, partially offset by fully depreciated legacy assets.

**Broadband** revenues increased in 2025, driven by an increase in fiber revenues of 17.0%. Higher fiber revenues reflect an increase in fiber customers, which we expect to continue as we invest further in building our fiber footprint, and higher ARPU. This increase also includes growth in AIA revenues and was partially offset by declines in copper-based broadband services.

**Legacy voice and data service** revenues decreased in 2025, reflecting the continued decline in demand for these services in favor of other technologies, such as wireless and fiber services.

**Other service and equipment** revenues decreased in 2025, reflecting the continued decline in the number of VoIP customers.

**Operations and support** expenses decreased in 2025, driven by lower customer support costs and content licensing fees, offset by higher network-related expenses and marketing costs.

**Depreciation** expense increased in 2025, primarily due to ongoing capital spending for strategic initiatives such as fiber and network upgrades and expansion, partially offset by fully depreciated legacy assets.

**Operating income** increased in 2025 and 2024. Our Consumer Wireline operating income margin was 10.9% in 2025, 6.4% in 2024 and 4.9% in 2023. Our Consumer Wireline EBITDA margin was 37.0% in 2025, 33.4% in 2024 and 31.3% in 2023.

**OPERATING ENVIRONMENT AND TRENDS OF THE BUSINESS**

**2026 Revenue Trends** We expect revenue growth in our wireless and broadband businesses as customers demand instant connectivity and higher speeds made possible by wireless network enhancements through 5G deployment and our fiber network expansion. We believe that our simplified go-to-market strategy for 5G in underpenetrated markets will continue to contribute

to wireless subscriber and service revenue growth and that expansion of our fiber and AIA serviceable locations will drive greater demand for broadband services. We expect that an increasing portion of our revenues will come from converged customers with seamless connectivity through an innovative product portfolio and strong customer relationships.

As we expand our fiber reach, we will be orienting our business portfolio to leverage this opportunity to offset continuing declines in legacy Business Wireline products by growing connectivity with small to mid-sized businesses. We plan to use our strong fiber and wireless assets, broad distribution and integrated product offerings to strengthen our overall market position. We will continue to rationalize our product portfolio with a longer-term shift of the business to fiber and wireless connectivity, and growth in value-added services. As customers are demanding faster and more reliable services, we are decommissioning our legacy copper network and enhancing our offerings to include services that provide better experiences over newer technologies, such as AT&T Internet Air.

**2026 Expense Trends** During 2026, we expect expense trends consistent with the prior year, and that we will continue to focus on efficiency, led by our cost transformation initiative. We expect the spending required to support growth and efficiency initiatives, primarily our continued deployment of fiber and 5G, to pressure expense trends in 2026. These investments will help prepare us to meet the continued increase in customer demand for enhanced wireless and broadband services, including on-the-go video streaming, augmented reality, "smart" technologies, user generated content and AI. Our network modernization efforts should result in a more efficient use of capital and lower network-related expenses in the coming years. Furthermore, access to our network and newer technology may drive customers to upgrade devices and equipment, the expenses associated with those equipment sales are expected to contribute to higher costs.

We continue to transform our operations to be more efficient and effective. We are restructuring businesses, working with regulators and customers to sunset legacy networks, improving customer service and ordering functions through digital transformation, sizing our support costs and staffing with current activity levels, and reassessing overall benefit costs. We also expect cost savings through AI-driven efficiencies in network design and operations, software development, sales, marketing, customer support services and general and administrative costs.

**Market Conditions** In recent years, uncertainty surrounding global growth rates, tariffs, inflation and a higher interest rate environment continued to produce volatility in the credit, currency and equity markets. We expect ongoing pressure on pricing during 2026 as we respond to the geopolitical and macroeconomic environment and our competitive marketplace, especially in wireless services.

Included on our consolidated balance sheets are assets held by benefit plans for the payment of future benefits. Our pension plans are subject to funding requirements of the Employee Retirement Income Security Act of 1974, as amended (ERISA). We plan to voluntarily contribute approximately $350 to our pension plans in 2026 and expect only minimal ERISA contribution requirements. Investment returns on these assets depend largely on trends in the economy, and a weakness in the equity, fixed income and real asset markets could require us to make future contributions to the pension plans. In addition, our policy of recognizing actuarial gains and losses related to our pension and other postretirement plans in the period in which they arise subjects us to earnings volatility caused by changes in market conditions; however, these actuarial gains and losses do not impact segment performance as they are required to be recorded in "Other income (expense) – net." Changes in our discount rate, which are tied to changes in the bond market, and changes in the performance of equity markets, may have significant impacts on the valuation of our pension and other postretirement obligations at the end of 2026 (see "Critical Accounting Policies and Estimates").

**Expected Growth Areas** Over the next few years, we expect our growth to come from wireless and IP-based fiber broadband services. We provide integrated services to diverse groups of customers in the United States. on a converged telecommunications network utilizing different technological platforms. In 2026, our key initiatives include:

• Continuing our wireless subscriber momentum and 5G deployment, with expansion of wireless subscribers in underpenetrated markets and converged connectivity.

• Continuing our fiber deployment, improving fiber penetration, growing AT&T Internet Air services, accelerating connectivity growth and increasing broadband revenues, inclusive of impact of integrating recent acquisitions of spectrum and fiber assets.

• Continuing our deployment of Open RAN to build a more robust ecosystem of network infrastructure providers and suppliers, fostering lower network costs, improved operational efficiencies and allowing for continued investment in our fast-growing broadband network.

• Continuing to drive efficiencies and a competitive advantage through cost transformation initiatives, including modernization of our IT infrastructure and product simplification.

*Wireless* We expect to continue to deliver revenue growth in the coming years. We are in a period of rapid growth in wireless video and data usage and believe that there are substantial opportunities available for next-generation integrated services that

combine technologies and services. As of December 31, 2025, we served 145 million wireless subscribers in North America, with 120 million in the United States.

Our LTE technology covers over 441 million people in North America, and in the United States, we cover all major metropolitan areas and over 337 million people. At December 31, 2025, our network covers more than 322 million people with 5G technology in the United States and North America. When combined with our upgraded backhaul network, we provide enhanced network capabilities and superior mobile broadband speeds for data and video services.

Our networks covering both the United States and Mexico have enabled our customers to use wireless services without roaming on other companies' networks. At December 31, 2025, we provided LTE coverage to over 104 million people in Mexico.

*Integration of Wireless and Fiber Services* The communications industry has evolved into internet-based technologies capable of converging the offering of wireline and wireless services. As the owner and operator of scaled wireless and fiber networks, we plan to continue to focus on expanding our wireless network capabilities and providing broadband offerings that allow customers to integrate their home or business fixed services with their mobile service. We intend to continue to develop and provide unique integrated mobile and broadband/fiber solutions.

**REGULATORY LANDSCAPE**

AT&T subsidiaries operating within the United States are subject to federal and state regulatory authorities. While these issues may apply only to certain subsidiaries, the words "we," "AT&T" and "our" are used to simplify the discussion. The following discussions are intended as a condensed summary of the issues rather than as a comprehensive legal analysis and description of all of these specific issues.

**International Regulation** 

Our subsidiaries operating outside the United States are subject to the jurisdiction of regulatory authorities in the territories in which the subsidiaries operate. Our licensing, compliance and advocacy initiatives in foreign countries primarily enable the provision of enterprise (i.e., large business) services globally and wireless services in Mexico.

The General Data Protection Regulation went into effect in Europe in May of 2018. This regulation created a range of new compliance obligations and significantly increased financial penalties for noncompliance. AT&T processes and handles personal data of its customers and subscribers, employees of its enterprise customers and its employees.

**U.S. Regulation** 

In the Telecommunications Act of 1996 (Telecom Act), Congress established a national policy framework intended to bring the benefits of competition and investment in advanced telecommunications facilities and services to all Americans by opening all telecommunications markets to competition and reducing or eliminating regulatory burdens that harm consumer welfare. Nonetheless, since then, the FCC and some state regulatory commissions have maintained, re-imposed or expanded certain regulatory requirements that were imposed decades ago on our traditional wireline subsidiaries when they operated as legal monopolies. Recently, the FCC's regulatory approach has depended on control of the executive branch, eliminating a variety of antiquated and unnecessary regulations in a number of areas, while imposing or re-imposing regulations in other areas. We continue to support regulatory and legislative measures and efforts, at both the state and federal levels, to reduce inappropriate regulatory burdens that inhibit our ability to compete effectively and offer needed services to our customers, including initiatives to transition services from traditional networks to all IP-based networks. At the same time, we also seek to ensure that legacy regulations are not further extended to broadband or wireless services, which are subject to vigorous competition. We have organized the following discussion by service impacted.

*Internet* Until 2015, the FCC classified fixed and mobile consumer broadband internet access services as information services subject to minimal regulation. In 2015, the FCC reclassified such services as telecommunications services subject to broader regulation by the FCC and imposed "net neutrality rules." Since then, the FCC has twice reversed course, most recently again reclassifying such services as telecommunications services subject to broader regulation by the FCC in an order adopted on April 25, 2024. Multiple trade associations and other parties challenged the FCC's reclassification decision in appeals consolidated in the U.S. Court of Appeals for the Sixth Circuit. The trade associations petitioned the Sixth Circuit to stay the FCC's order. On August 1, 2024, the Sixth Circuit issued a stay of the FCC order pending review of the appeals, holding that broadband providers are likely to succeed on the merits. On January 2, 2025, the Sixth Circuit issued an order granting the petition for review and setting aside the FCC net neutrality order, holding that broadband internet access service is an information service.

In 2021, New York enacted the Affordable Broadband Act (ABA), requiring ISPs offering "fixed" mass-market broadband service, including fixed wireless, to offer discounted plans to low-income customers. In June 2021, the ABA was enjoined by a federal district court, which found the ABA preempted by federal law. In April 2024, the Second Circuit overruled and vacated the district court order. The Supreme Court subsequently denied the trade association's request for review. Under an agreement

with the New York Attorney General, the law began to be enforced on January 15, 2025. A number of state legislatures have since considered legislation regulating the rates of fixed broadband service, with Connecticut adopting a law requiring wireline ISPs that are state contractors to stand up a discounted broadband offering to low-income customers.

Since 2018, some states have adopted legislation or issued executive orders that established state net neutrality rules, including California, Maine, Minnesota, Vermont and Washington. Additional states may seek to impose net neutrality requirements in the future.

On November 15, 2023, the FCC adopted rules to "facilitate" equal access to broadband and prevent digital discrimination in broadband access. The rules, which became effective March 22, 2024, prohibit covered entities from implementing policies or practices not justified by genuine issues of technical or economic feasibility, that differentially impact consumers' access to broadband internet access service based on prohibited characteristics (including income level, race and ethnicity) or that have such differential impact, whether intentional or not. The rules broadly apply prospectively to all aspects of an ISP's service that could impact a consumer's ability to access broadband, including deployment, marketing and credit checks, among other things. We may be required to answer complaints alleging that the company has violated the FCC rules, and those complaints may seek relief, including changes to our business practices or civil forfeitures that could result in significant costs or reputational harm. It is currently uncertain how the FCC will enforce these new rules. Several business associations have filed appeals challenging the rules and several of those appeals have been consolidated in the Eighth Circuit, which held oral argument on September 25, 2024.

Privacy-related legislation continues to be adopted or considered in a number of jurisdictions. Legislative, regulatory and litigation actions could result in increased costs of compliance, further regulation or claims against broadband internet access service providers and others, and increased uncertainty in the value and availability of data.

*Infrastructure Investment* On November 15, 2021, the Infrastructure Investment and Jobs Act (IIJA) was signed into law. The legislation appropriates $65,000 to support broadband deployment and adoption. The National Telecommunications and Information Agency (NTIA) is responsible for distributing more than $48,000 of this funding, including $42,500 in state grants for broadband deployment projects in unserved and underserved areas through the Broadband, Equity, Access and Deployment (BEAD) Programs. NTIA and states are in the process of administering these grants. Where appropriate, AT&T has applied for, and in some cases has been awarded, and may continue to apply for grants under this or other government infrastructure programs.

*Wireless* Industry-wide network densification and 5G technology expansion efforts, which are needed to satisfy extensive demand for video and internet access, will involve significant deployment of "small cell" equipment. This increases the importance of local permitting processes that allow for the placement of small cell equipment in the public right-of-way on reasonable timelines and terms. The FCC has adopted multiple Orders streamlining federal, state and local wireless structure review processes that had the tendency to delay and impede deployment of small cell and related infrastructure used to provide telecommunications and broadband services. Additional spectrum will be needed industrywide for 5G and future services. On July 4, 2025, as part of the omnibus reconciliation package (One Big Beautiful Bill (OBBB)), the President signed into law a provision that reauthorized, for 10 years, FCC statutory authority to conduct spectrum auctions and further required auction of 800 MHz of spectrum within eight years. The FCC's implementation of this legislation will have a direct impact on whether the wireless industry has sufficient spectrum to support future wireless services. As a first step, in November 2025, the FCC opened a rulemaking to consider the auctioning of spectrum in the upper C-Band, as required by OBBB.

**ACCOUNTING POLICIES AND STANDARDS** 

**Critical Accounting Policies and Estimates** Because of the size of the financial statement line items they relate to or the extent of judgment required by our management, some of our accounting policies and estimates have a more significant impact on our consolidated financial statements than others.

**Pension and Postretirement Benefits** Our actuarial estimates of retiree benefit expense and the associated significant weighted-average assumptions are discussed in Note 14. Our assumed weighted-average discount rates for pension and postretirement benefits of 5.50% and 5.30%, respectively, at December 31, 2025, reflect the hypothetical rate at which the projected benefit obligations could be effectively settled or paid out to participants. We determined our discount rate based on a range of factors, including a yield curve composed of the rates of return on several hundred high-quality, fixed income corporate bonds available at the measurement date and corresponding to the related expected durations of future cash outflows for the obligations. These bonds had an average rating of at least Aa3 or AA- by the nationally recognized statistical rating organizations, denominated in U.S. dollars, and generally not callable, convertible or index linked. For the year ended December 31, 2025, when compared to the year ended December 31, 2024, we decreased our pension discount rate by 0.20%, resulting in an increase in our pension plan benefit obligation of $680, and decreased our postretirement discount rate by 0.30%, resulting in an increase in our postretirement benefit obligation of $167.

Our expected long-term rate of return is 7.75% on pension plan assets and 4.00% on postretirement plan assets for 2025 and 2026. Our expected return on plan assets is calculated using the actual fair value of plan assets. If all other factors were to remain unchanged, we expect that a 0.50% decrease in the expected long-term rate of return would cause 2026 combined pension and postretirement cost to increase $139, which under our accounting policy would be adjusted to actual returns in the current year upon remeasurement of our retiree benefit plans.

We recognize gains and losses on pension and postretirement plan assets and obligations immediately in "Other income (expense) – net" in our consolidated statements of income. These gains and losses are generally measured annually as of December 31, and accordingly, will normally be recorded during the fourth quarter, unless an earlier remeasurement is required. Should actual experience differ from actuarial assumptions, the projected pension benefit obligation and net pension cost and accumulated postretirement benefit obligation and postretirement benefit cost would be affected in future years. See Note 14 for additional discussions regarding our assumptions.

**Asset Valuations and Impairments** Goodwill and other indefinite-lived intangible assets are not amortized but tested at least annually on October 1 for impairment. For impairment testing, we estimate fair values using models that predominantly rely on the expected cash flows to be derived from the reporting unit or use of the asset. Long-lived assets are reviewed for impairment whenever events or circumstances indicate that the book value may not be recoverable over the remaining life. Inputs underlying the expected cash flows include, but are not limited to, subscriber counts, revenue per user, capital investment and acquisition costs per subscriber, and ongoing operating costs. We based our assumptions on a combination of our historical results, trends, business plans and marketplace participant data.

*Annual Goodwill Testing*

Goodwill is tested on a reporting unit basis by comparing the estimated fair value of each reporting unit to its book value. If the fair value exceeds the book value, then no impairment is measured. We estimate fair values using an income approach (also known as a discounted cash flow model) and market multiple approaches. The income approach utilizes our future cash flow projections with a perpetuity value discounted at an appropriate weighted average cost of capital. The market multiple approach uses the multiples of publicly traded companies whose services are comparable to those offered by the reporting units.

As of October 1, 2025, the calculated fair values of the reporting units with remaining goodwill exceeded their book values in all circumstances in excess of 10%. If either the projected long-term growth rates declined by 0.5%, if the projected long-term EBITDA margin declined by 0.5%, or if the weighted average cost of capital increased by 0.5%, the fair values would still be higher than the book value of the reporting units.

The fair values of our remaining reporting units could be negatively impacted by future sustained declines in macroeconomic or business conditions, higher discount rates or declines in the value of AT&T stock and could result in goodwill impairment charges in future periods.

*U.S. Wireless Licenses*

We have the option to first perform a qualitative assessment to determine whether it is more likely than not that the book value of our wireless licenses exceeds the fair value. On a periodic basis, or if the qualitative assessment indicates potential impairment, we will perform a quantitative impairment test.

Our quantitative assessment involves assessing the fair value of U.S. wireless licenses using a discounted cash flow model (the Greenfield Approach) and a qualitative corroborative market approach based on auction prices, depending upon auction activity. The Greenfield Approach assumes a company initially owns only the wireless licenses and makes investments required to build an operation comparable to current use. These licenses are tested annually for impairment on an aggregated basis, consistent with their use on a national scope for the United States. For impairment testing, we assume subscriber and revenue growth will trend up to projected levels, with a long-term growth rate reflecting expected long-term inflation trends. We assume churn rates will initially exceed our current experience but decline to rates that are in line with industry-leading churn.

During 2025, we performed a qualitative impairment assessment that considered several factors, including macroeconomic conditions, industry and regulatory considerations, recent and projected performance of the reporting unit and the prior quantitative impairment testing results. The qualitative assessment indicated it is more likely than not that the fair value of our wireless licenses exceeded the book value; thus, a quantitative assessment was not performed.

For our most recent quantitative assessment, which was performed in 2024, we used a discount rate of 8.75%, based on the optimal long-term capital structure of a market participant and its associated cost of debt and equity for the licenses, to calculate the present value of the projected cash flows. The quantitative impairment assessment indicated the fair value of our wireless licenses exceeded their book value by more than 10%. If either the projected rate of long-term growth of cash flows or revenues

------

---

| |
|:---|
| **AT&T Inc.** |
| Dollars in millions except per share amounts |

---

declined by 0.5%, or if the discount rate increased by 0.5%, the fair values of these wireless licenses would still be higher than the book value.

**Income Taxes** Our estimates of income taxes and the significant items giving rise to the deferred assets and liabilities are shown in Note 13 and reflect our assessment of actual future taxes to be paid on items reflected in the financial statements, giving consideration to both timing and probability of these estimates. Actual income taxes could vary from these estimates due to future changes in income tax law or the final review of our tax returns by federal, state or foreign tax authorities.

We use our judgment to determine whether it is more likely than not that we will sustain positions that we have taken on tax returns and, if so, the amount of benefit to initially recognize within our financial statements. We regularly review our uncertain tax positions and adjust our unrecognized tax benefits (UTBs) in light of changes in facts and circumstances, such as changes in tax law, interactions with taxing authorities and developments in case law. These adjustments to our UTBs may affect our income tax expense. Settlement of uncertain tax positions may require use of our cash.

**New Accounting Standards**

See Note 1 for discussion of recently issued or adopted accounting standards.

**OTHER BUSINESS MATTERS** 

**Environmental** We are subject from time to time to judicial and administrative proceedings brought by various governmental authorities under federal, state or local environmental laws. We reference in our Forms 10-Q and 10-K certain environmental proceedings that could result in monetary sanctions (exclusive of interest and costs) of three hundred thousand dollars or more. However, we do not believe that any of those currently pending will have a material adverse effect on our results of operations.

We had $18,234 in cash and cash equivalents available at December 31, 2025, increasing $14,936 since December 31, 2024. Cash and cash equivalents included cash of $3,521 and money market funds and other cash equivalents of $14,713. Approximately $1,330 of our cash and cash equivalents were held in accounts outside of the United States and may be subject to restrictions on repatriation. Our cash and cash equivalents at December 31, 2025 was elevated in anticipation of the consummation of announced transactions. (See Note 6)

In 2025, cash inflows were primarily provided by cash receipts from operations, including cash from our sale and transfer of our receivables to third parties, and the disposition of our investment in DIRECTV. These inflows exceeded cash used to meet the needs of the business, including, but not limited to, payment of operating expenses, including higher device payments from higher sales volumes. The cash generated from operating activities was primarily used to fund capital improvements, make dividend payments to stockholders, repurchase preferred and common stock, and repay long-term debt. We maintain availability under our credit facilities and our commercial paper program to meet our short-term liquidity requirements.

Refer to "Contractual Obligations" discussion below for additional information regarding our cash requirements.

**Cash Provided by Operating Activities** 

During 2025, cash provided by operating activities was $40,284, compared to $38,771 in 2024, driven by operational growth and lower cash tax payments. Partially offsetting this increase and lowering cash from operations during 2025 were voluntarily pension contributions of approximately $1,150 and advanced cash payments of about $900 to Frontier Communications, a subsidiary of Verizon Communications Inc.

We actively manage the timing of our supplier payments for operating items to optimize the use of our cash. Among other things, we seek to make payments on 90-day or greater terms, while providing the suppliers with access to bank facilities that

------

---

| |
|:---|
| **AT&T Inc.** |
| Dollars in millions except per share amounts |

---

permit earlier payments at their cost (referred to as supplier financing program). In addition, for payments to suppliers of handset inventory, as part of our working capital initiatives, we have arrangements that allow us to extend the stated payment terms by up to 90 days at an additional cost to us (referred to as direct supplier financing). The net impact of direct supplier financing, including principal and interest payments, was to improve cash from operating activities $443 in 2025 and $661 in 2024. All supplier financing payments are due within one year. (See Note 22)

**Cash Used in Investing Activities**

During 2025, cash used in investing activities totaled $18,777, consisting primarily of $20,842 (including interest during construction) for capital expenditures. During 2025, investing activities also included $148 of FirstNet sustainability receipts net of investment and $620 for our investment in a new strategic partner, DriveNets, related to wireline network transformation accounted for under the equity method of accounting.

On July 2, 2025, we completed the sale of our interest in DIRECTV to TPG and recorded a current note receivable of approximately $3,600, of which we had received $3,100 by the end of 2025, and a long-term note receivable of $500. (See Note 10)

We enter into multi-year software licensing arrangements, which are typically paid over the license terms of two to five years and referred to as vendor financing. Additionally, for capital improvements, we have negotiated favorable vendor payment terms of 120 days or more with some of our vendors, which are also referred to as vendor financing. Vendor financing is excluded from capital expenditures and reported as financing activities. Vendor financing payments were $1,181 in 2025, compared to $1,792 in 2024. Capital expenditures in 2025 were $20,842, and when including $1,181 cash paid for vendor financing, capital investment was $22,023 ($32 lower than the prior year).

The vast majority of our capital expenditures are spent on our networks, including product development and related support systems. In 2025, we placed $1,594 of productive assets in service under vendor financing arrangements (compared to $700 in 2024).

In November 2024, we agreed to purchase select spectrum licenses from United States Cellular Corporation (UScellular) for approximately $1,000, subject to closing conditions, including the consummation of UScellular's sale of its wireless operations and select spectrum assets to T-Mobile US, Inc. We completed our acquisition of these licenses on January 13, 2026, with a cash payment of $1,018.

On May 21, 2025, we agreed to acquire substantially all of Lumen's Mass Markets fiber business for $5,750 in cash, subject to purchase price adjustments. At the time of signing, the pending acquisition covered approximately one million fiber customers, and also included fiber network assets that reached more than four million fiber locations. On February 2, 2026, we completed the transaction and expect to manage the customer relationships in our Consumer Wireline business and place the fiber network assets in a new, wholly owned subsidiary. We plan to sell a controlling interest in the subsidiary to an equity partner that will co-invest in the ongoing business, and, as such, it is expected to meet the criteria for discontinued operations.

On August 25, 2025, we agreed to purchase FCC licenses in the 600 MHz and 3.45 GHz bands from EchoStar for approximately $23,000, subject to certain adjustments. The transaction is expected to close in early 2026 and is subject to regulatory approval and other closing conditions. The FCC licenses will be used to expand our 5G network, meet future capacity demands and support future wireless communications services. We signed a short-term spectrum manager lease on the 3.45 GHz spectrum, which was deployed in cell sites covering nearly two-thirds of the U.S. population.

The amount of capital expenditures is influenced by demand for services and products, capacity needs and network enhancements. In 2026, we expect that our capital investment, which includes capital expenditures and cash paid for vendor financing, will be in the $23,000 to $24,000 range.

**Cash Provided by or Used in Financing Activities** 

In 2025, cash used in financing activities totaled $6,386 and was comprised of dividend payments, common and preferred stock repurchases, debt repayments and vendor financing payments, partially offset by issuances of long-term debt and issuances of preferred interests in a subsidiary.

A tabular summary of our debt activity during 2025 is as follows:

The weighted average interest rate of our long-term debt portfolio, including credit agreement borrowings and the impact of derivatives, was approximately 4.2% as of December 31, 2025 and 2024. We had $134,718 of total notes and debentures outstanding at December 31, 2025. This also included Euro, British pound sterling, Canadian dollar, Australian dollar and Swiss franc denominated debt that totaled approximately $35,307.

At December 31, 2025, we had $9,011 of long-term debt maturing within one year. We had no outstanding commercial paper borrowings or other short-term borrowings on December 31, 2025.

During 2025, we paid $1,181 of cash under our vendor financing program, compared to $1,792 in 2024. Total vendor financing payables included in our December 31, 2025 consolidated balance sheet were $1,892, with $956 due within one year (in "Accounts payable and accrued liabilities") and the remainder predominantly due within five years (in "Other noncurrent liabilities").

During 2025, we repurchased approximately 159 million shares totaling $4,269 under our $10,000 common stock repurchase authorization approved by the Board of Directors in December 2024, excluding brokerage fees and the one percent excise tax imposed by the Inflation Reduction Act of 2022. At December 31, 2025, we had approximately $5,731 remaining under this 2024 repurchase authorization. On January 27, 2026, the Board approved an authorization to repurchase an additional $10,000 of common stock.

We paid dividends on common and preferred shares of $8,180 in 2025, compared with $8,208 in 2024. Dividends on common stock declared by our Board of Directors totaled $1.11 per share in 2025 and in 2024. Our dividend policy considers the expectations and requirements of stockholders, capital funding requirements of AT&T and long-term growth opportunities.

Financing activities in 2025 also included the issuance of $2,250 of nonconvertible cumulative preferred interests in Telco LLC, with the funds used to redeem all outstanding Series B preferred stock for $2,075 (see Note 16). We also received approximately $850 in upfront cash proceeds from a structured sale-leaseback of real estate.

On February 5, 2026, we issued $6,500 principal amount of global notes due 2031 to 2056 with a weighted average coupon of 5.2%. We intend to use the net proceeds from this issuance for general corporate purposes, which may include debt repayments and pending acquisitions.

Our 2026 financing activities will focus on managing our debt level, funding pending acquisitions, paying dividends, subject to approval by our Board of Directors, and repurchasing common stock when deemed appropriate. We plan to fund our financing

uses of cash through a combination of cash from operations, issuance of debt and asset sales. The timing and mix of any debt issuance and/or refinancing will be guided by credit market conditions and interest rate trends.

**Credit Facilities**

The following summary of our various credit and loan agreements does not purport to be complete and is qualified in its entirety by reference to each agreement filed as exhibits to our Annual Report on Form 10-K.

We use credit facilities as a tool in managing our liquidity status. On November 3, 2025, we entered into (i) a $12,000 Second Amended and Restated Credit Agreement (Revolving Credit Agreement), with Citibank, N.A., as agent, amending and restating our existing $12,000 Amended and Restated Credit Agreement, dated as of November 18, 2022, and (ii) a $17,500 Delayed Draw Term Loan Credit Agreement (Term Loan), with Bank of America, N.A., as agent. No amount was outstanding under the Revolving Credit Agreement or the Term Loan as of December 31, 2025. (See Note 11)

We also utilize other external financing sources, which include various credit arrangements supported by government agencies to support network equipment purchases as well as a commercial paper program.

The Revolving Credit Agreement and the Term Loan contain covenants that are customary for an issuer with investment grade senior debt credit ratings, including a net debt-to-EBITDA financial ratio covenant requiring us to maintain, as of the last day of each fiscal quarter, a ratio of not more than 3.75-to-1. As of December 31, 2025, we were in compliance with the covenants for our credit facilities.

**Collateral Arrangements**

Most of our counterparty collateral arrangements require cash collateral posting by AT&T only when derivative market values exceed certain thresholds. Under these arrangements, which cover the majority of our $35,741 derivative portfolio, counterparties are still required to post collateral. During 2025, we posted $11 of cash collateral, on a net basis. Cash postings under these arrangements vary with changes in credit ratings and netting agreements. (See Note 12)

**Other**

Our total capital consists of debt (long-term debt and debt maturing within one year), redeemable noncontrolling interest and stockholders' equity. Our capital structure does not include debt issued by our equity method investments. At December 31, 2025, our debt ratio was 51.4%, compared to 50.7% at December 31, 2024 and 53.5% at December 31, 2023. The debt ratio is affected by the same factors that affect total capital, and reflects our recent debt issuances, repayments and reclassifications related to redemption of noncontrolling interests.

A significant amount of our cash outflows is related to tax items, acquisition of spectrum and benefits paid for current and former employees:

• Total taxes incurred, collected and remitted by AT&T during 2025 and 2024 were $16,326 and $16,968. These taxes include income, franchise, property, sales, excise, payroll, gross receipts and various other taxes and fees.

• Total domestic spectrum acquired primarily through FCC auctions, including cash, exchanged spectrum, auction deposits and spectrum relocation and clearing costs, was approximately $379 in 2025, $380 in 2024 and $2,940 in 2023.

• Total health and welfare benefits provided to certain active and retired employees and their dependents totaled approximately $2,490 in 2025 and $2,550 in 2024, with $483 paid from plan assets in 2025, compared to $736 in 2024. Of those benefits, approximately $2,220 related to medical and prescription drug benefits in 2025, compared to $2,290 in 2024. We paid $2,957 of pension benefits out of plan assets in 2025, compared to $2,447 in 2024.

**Contractual Obligations**

Our contractual obligations as of December 31, 2025, and the estimated timing of payment, are in the following table:

---

<sup>1</sup>Represents principal or payoff amounts of notes, debentures and credit agreement borrowings at maturity (see Note 11). Foreign debt includes the impact from hedges, when applicable.

<sup>2</sup>Includes credit agreement borrowings.

<sup>3</sup>We expect to fund the purchase obligations with cash on hand, which may include cash provided by operations or through incremental borrowings. The minimum commitment for certain obligations is based on termination penalties that could be paid to exit the contracts. (See Note 21)

<sup>4</sup>Represents operating lease payments (see Note 8).

<sup>5</sup>Represents contractual commitment to make sustainability payments over the 25-year contract. These sustainability payments represent our commitment to fund FirstNet's operating expenses and future reinvestment in the network, which we own and operate. FirstNet has a statutory requirement to reinvest funds that exceed the agency's operating expenses, which we anticipate to be $15,000. (See Note 20)

<sup>6</sup>The noncurrent portion of the UTBs is included in the "More than 5 Years" column, as we cannot reasonably estimate the timing or amounts of additional cash payments, if any, at this time (see Note 13).

<sup>7</sup>Represents future minimum payments under the Crown Castle and other arrangements (see Note 18), payables subject to extended payment terms (see Note 22) and finance lease payments (see Note 8).

<sup>8</sup>Excludes debt transactions, pending acquisitions and other investment funding completed after December 31, 2025 (see Note 6).

Certain items were excluded from this table because the year of payment is unknown and could not be reliably estimated, we believe the obligations are immaterial, or the settlement of the obligation will not require the use of cash. These items include: deferred income tax liability of $58,312 (see Note 13); net postemployment benefit obligations of $9,113 (including current portion); and other noncurrent liabilities of $7,155.

**DISCUSSION AND RECONCILIATION OF NON-GAAP MEASURES**

We also evaluate segment and business unit performance based on EBITDA, which is defined as operating income excluding depreciation and amortization, and/or EBITDA margin, which is defined as EBITDA divided by total revenue. 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. There are material limitations to using these non-GAAP financial measures. EBITDA and EBITDA margin, as we have defined them, may not be comparable to similarly titled measures reported by other companies.

**ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

We are exposed to market risks primarily from changes in interest rates and foreign currency exchange rates. These risks, along with other business risks, impact our cost of capital. It is our policy to manage our debt structure and foreign exchange exposure in order to manage capital costs, control financial risks and maintain financial flexibility over the long term. In managing market risks, we employ derivatives according to documented policies and procedures, including interest rate swaps, interest rate locks, foreign currency exchange contracts and combined interest rate foreign currency contracts (cross-currency swaps). We do not use derivatives for trading or speculative purposes. We do not foresee significant changes in the strategies we use to manage market risk in the near future.

One of the most significant assumptions used in estimating our postretirement benefit obligations is the assumed weighted-average discount rate, which is the hypothetical rate at which the projected benefit obligations could be effectively settled or paid out to participants. We determined our discount rate based on a range of factors, including a yield curve composed of the rates of return on several hundred high-quality, fixed income corporate bonds available at the measurement date and corresponding to the related expected durations of future cash outflows for the obligations. In recent years, the discount rates have been increasingly volatile, and on average have been lower than in historical periods. Lower discount rates used to measure our pension and postretirement plans result in higher obligations. Future increases in these rates could result in lower obligations, improved funded status and actuarial gains.

**Interest Rate Risk**

The majority of our financial instruments are medium- and long-term fixed-rate notes and debentures. Changes in interest rates can lead to significant fluctuations in the fair value of these instruments. The principal amounts by expected maturity, average interest rate and fair value of our liabilities that are exposed to interest rate risk are described in Notes 11 and 12. In managing interest expense, we control our mix of fixed- and floating-rate debt through term loans, floating-rate notes, and interest rate swaps. We have established interest rate risk limits that we closely monitor by measuring interest rate sensitivities in our debt and interest rate derivatives portfolios.

Our foreign-denominated long-term debt has been swapped from fixed-rate or floating-rate foreign currencies to fixed-rate U.S. dollars at issuance through cross-currency swaps, removing interest rate risk and foreign currency exchange risk associated with the underlying interest and principal payments. Likewise, periodically we enter into interest rate locks to partially hedge the risk of increases in the benchmark interest rate during the period leading up to the probable issuance of fixed-rate debt. We expect gains or losses on our cross-currency swaps and interest rate locks to offset the losses and gains in the financial instruments they hedge.

We had no interest rate swaps and no interest rate locks at December 31, 2025.

**Foreign Exchange Risk**

We principally use foreign exchange contracts to hedge costs and debt denominated in foreign currencies. We are also exposed to foreign currency exchange risk through our foreign affiliates and equity investments in foreign companies.

Through cross-currency swaps, our foreign-denominated debt has been swapped from fixed-rate or floating-rate foreign currencies to fixed-rate U.S. dollars at issuance, removing interest rate and foreign currency exchange risk associated with the underlying interest and principal payments. We expect gains or losses in our cross-currency swaps to offset the gains and losses in the financial instruments they hedge. We had cross-currency swaps with a notional value of $35,741 and a fair value of $(1,174) outstanding at December 31, 2025.

For the purpose of assessing specific risks, we use a sensitivity analysis to determine the effects that market risk exposures may have on the fair value of our financial instruments and results of operations. We had no foreign exchange forward contracts at December 31, 2025.

**AT&T Inc.**

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM** 

To the Stockholders and the Board of Directors of AT&T Inc.

**Opinion on the Financial Statements** 

We have audited the accompanying consolidated balance sheets of AT&T Inc. (the Company) as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, cash flows and changes in stockholders' equity for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 9, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion** 

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company 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. 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.

**Critical Audit Matters** 

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

| | **Discount rates used in determining pension and postretirement benefit obligations**  |
| *Description of the Matter* | At December 31, 2025, the Company's defined benefit pension obligation was $30,627 million and exceeded the fair value of pension plan assets of $28,677 million, resulting in an unfunded benefit obligation of $1,950 million. Additionally, at December 31, 2025, the Company's postretirement benefit obligation was $6,477 million and exceeded the fair value of postretirement plan assets of $722 million, resulting in an unfunded benefit obligation of $5,755 million. As explained in Note 14 to the consolidated financial statements, the Company updates the assumptions used to measure the defined benefit pension and postretirement benefit obligations, including discount rates, at December 31 or upon a remeasurement event. The Company determines the discount rates used to measure the obligations based on the development of a yield curve using high-quality corporate bonds selected to yield cash flows that correspond to the expected timing and amount of the expected future benefit payments.  |

|:---|:---|
| | Auditing the defined benefit pension and postretirement benefit obligations was complex due to the judgmental nature of the actuarial assumptions made by management, primarily the discount rates, used in the Company's measurement process. The discount rates have a significant effect on the measurement of the defined benefit pension and postretirement benefit obligations, and auditing the discount rates was complex because it required an evaluation of the credit quality of the corporate bonds used to develop the discount rates and the correlation of those bonds' cash inflows to the timing and amount of future expected benefit payments. |
| *How We <br>Addressed the Matter in Our <br>Audit* | We obtained an understanding, evaluated the design and tested the operating effectiveness of certain controls over management's review of the determination of the discount rates used in the defined benefit pension and postretirement benefit obligations calculations.  |
| *How We <br>Addressed the Matter in Our <br>Audit* |  |
| *How We <br>Addressed the Matter in Our <br>Audit* | To test the determination of the discount rates used in the calculation of the defined benefit pension and postretirement benefit obligations, we performed audit procedures that focused on evaluating, with the assistance of our actuarial specialists, the determination of the discount rates, among other procedures. For example, we evaluated the selected yield curve used to determine the discount rates applied in measuring the defined benefit pension and postretirement benefit obligations. As part of this assessment, we considered the credit quality of the corporate bonds that comprised the yield curve and compared the timing and amount of cash flows at maturity with the expected amounts and duration of the related benefit payments. |
|  | **Evaluation of goodwill for impairment** |
| *Description of the Matter* | At December 31, 2025, the Company's goodwill balance was $63,425 million. As discussed in Note 1 to the consolidated financial statements, reporting unit goodwill is tested at least annually for impairment. Estimating fair value in connection with the impairment evaluation involves the utilization of discounted cash flow and market multiple approaches. |
| *Description of the Matter* |  |
| *Description of the Matter* | Auditing management's annual goodwill impairment test for the Consumer Wireline reporting unit was complex because the estimation of fair value involves subjective management assumptions, such as the projected long-term EBITDA margin and weighted average cost of capital, and complex valuation methodologies, such as the discounted cash flow and market multiple approaches. Assumptions used in these valuation models are forward-looking, and changes in these assumptions can have a material effect on the determination of fair value. |
| *How We Addressed the<br>Matter in Our <br>Audit* | We obtained an understanding, evaluated the design and tested the operating effectiveness of certain controls over the Company's impairment evaluation processes. Our procedures included testing controls over management's review of the valuation models and its determination of the significant assumptions described above. |
| *How We Addressed the<br>Matter in Our <br>Audit* |  |
| *How We Addressed the<br>Matter in Our <br>Audit* | Our audit procedures to test management's impairment evaluation included, among others, assessing the valuation methodologies and significant assumptions discussed above and the underlying data used to develop such assumptions. For example, we compared the significant assumptions to current industry, market and economic trends, and other guideline companies in the same industry. Where appropriate, we evaluated whether changes to the Company's business and other factors would affect the significant assumptions. We also assessed the historical accuracy of management's estimates and performed independent sensitivity analyses. We involved our valuation specialists to assist us in evaluating the methodologies and auditing the assumptions used to calculate the estimated fair value of the Consumer Wireline reporting unit.  |

**AT&T Inc.**

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Stockholders and the Board of Directors of AT&T Inc.

**Opinion on Internal Control Over Financial Reporting** 

We have audited AT&T Inc.'s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, AT&T Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2025 consolidated financial statements of the Company and our report dated February 9, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion** 

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Report of Management. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**Definition and Limitations of Internal Control Over Financial Reporting** 

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

**Notes to Consolidated Financial Statements**

**NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

**Basis of Presentation** Throughout this document, AT&T Inc. is referred to as "AT&T," "we" 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.

The consolidated financial statements include our controlled subsidiaries, as well as variable interest entities (VIE) where we are deemed to be the primary beneficiary. All significant intercompany transactions are eliminated in consolidation. Investments in entities that we do not control but have significant influence are accounted for under the equity method. We also record our proportionate share of our equity method investees' other comprehensive income (OCI) items, including translation adjustments. We treat distributions received from equity method investees as returns on investment and classify them as cash flows from operating activities until those distributions exceed our cumulative equity in the earnings of that investment. We treat the excess amount as a return of investment and classify it as cash flows from investing activities. In the event we receive dividends in excess of the carrying amount of the investment, and we have no obligation to provide financial support to the equity method investee, we treat those dividends as returns on investment and classify them as cash flows from operating activities.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions, including other 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. Moreover, unfavorable changes in market conditions, including interest rates, could adversely impact those estimates and result in asset impairments. Certain prior-period amounts have been conformed to the current period's presentation, providing further disaggregation of activities within Cash from Operations in our consolidated statements of cash flows and additional revenue categories for our Business Wireline and Consumer Wireline business units.

**Adopted and New Accounting Standards**

***Income Taxes*** In December 2023, the Financial Accounting Standards Board (FASB) issued ASU No. 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" (ASU 2023-09). Beginning with our 2025 annual reporting, we adopted, through retrospective application, ASU 2023-09, which requires that a public entity disclose specific categories in its annual income tax rate reconciliation table and provide additional qualitative information for reconciling items representing at least 5% of pre-tax income or loss from continuing operations, using the federal statutory tax rate. The standard also requires an annual breakdown of income taxes paid by jurisdiction (i.e., federal, state and foreign), with further disaggregation by jurisdictions representing at least 5% of total income taxes paid.

***Segment Reporting*** In November 2023, the FASB issued ASU No. 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" (ASU 2023-07). Beginning with our 2024 annual reporting, we adopted, through retrospective application, ASU 2023-07, which requires that a public entity disclose, on an interim and annual basis, significant segment expense categories and amounts that are regularly provided to its chief operating decision maker (CODM) and included in each reported measure of segment profit or loss. An entity must also disclose, by reportable segment, the amount and composition of other expenses. The standard requires an entity disclose the title and position of its CODM and explain how the CODM uses these reported measures in assessing segment performance and determining how to allocate resources.

***Convertible Instruments*** Beginning with 2022 interim reporting, we adopted, through retrospective application, 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). ASU 2020-06 requires that instruments which may be settled in cash or stock are presumed settled in stock in calculating diluted earnings per share. Prior to the April 2023 repurchase, settlement of our Series A Cumulative Perpetual Membership Interests in AT&T Mobility II LLC (Mobility preferred interests) could have resulted in additional dilutive impact, the magnitude of which was influenced by the fair value of the Mobility preferred interests and the average AT&T common stock price during the reporting period, which varied from period-to-period (see Note 16).

***Disaggregation of Income Statement Expenses*** In November 2024, the FASB issued ASU No. 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses" (ASU 2024-03), which requires that a public entity disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation and (d) intangible asset amortization included in each relevant expense caption presented on the face of the income statement. The standard also requires an entity to disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively as well as disclose the total

| **AT&T Inc.** |
| Dollars in millions except per share amounts |

---

amount of selling expenses and, annually, the entity's definition of selling expenses. ASU 2024-03 will be effective for annual periods beginning after December 15, 2026, with either retrospective or prospective application. The standard allows for early adoption of these requirements; we are currently evaluating the disclosure impacts of our adoption.

***Internal-Use Software*** In September 2025, the FASB issued ASU No. 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (ASU 2025-06). ASU 2025-06 removes references to prescriptive and sequential software development stages and requires software cost capitalization when management has authorized and committed to funding, and it is probable that the project will be completed, and the software used for its intended function. ASU 2025-06 will be effective for annual reporting periods beginning after December 15, 2027. We are evaluating the impacts of our adoption of ASU 2025-06 and currently do not expect that it will have a material impact on our financial statements.

**Accounting Policies**

**Income Taxes** We record deferred income taxes for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the computed tax basis of those assets and liabilities. We record valuation allowances against the deferred tax assets (included, together with our deferred income tax assets, as part of our reportable net deferred income tax liabilities on our consolidated balance sheets), for which the realization is uncertain. We review these items regularly in light of changes in federal, state and foreign tax laws and changes in our business.

On July 4, 2025, the One Big Beautiful Bill Act was enacted, which restores or makes permanent certain expiring business tax provisions from the Tax Cuts and Jobs Act of 2017. As a result of the legislation, we reduced our taxable income position in 2025. The legislation did not materially impact our income tax expense, but we expect it will result in a material decrease to cash taxes paid relative to our expectations. (See Note 13)

**Cash and Cash Equivalents** Cash and cash equivalents include all highly liquid investments with original maturities of three months or less. The carrying amounts approximate fair value. At December 31, 2025, we held $3,521 in cash and $14,713 in money market funds and other cash equivalents. Of our total cash and cash equivalents, $1,330 resided in foreign jurisdictions, some of which is subject to restrictions on repatriation.

**Allowance for Credit Losses** We record expense to maintain an allowance for credit losses for estimated losses that result from the failure or inability of our customers to make required payments deemed collectible from the customer when the service was provided or product was delivered. When determining the allowances for trade receivables and loans, we consider the probability of recoverability of accounts receivable based on past experience, taking into account current collection trends and general economic factors, including bankruptcy rates. We also consider future economic trends to estimate expected credit losses over the lifetime of the asset. Credit risks are assessed based on historical write-offs, net of recoveries, as well as an analysis of the aged accounts receivable balances with allowances generally increasing as the receivable ages. Accounts receivable may be fully reserved for when specific collection issues are known to exist, such as catastrophes or pending bankruptcies.

**Inventories** Inventories primarily consist of wireless devices and accessories and are valued at the lower of cost or net realizable value.

**Property, Plant and Equipment** Property, plant and equipment is stated at cost, except for assets acquired through business combinations, which are initially recorded at fair value. The cost of additions and substantial improvements to property, plant and equipment is capitalized, and includes internal compensation costs for these projects. The cost of maintenance and repairs of property, plant and equipment is charged to operating expenses. Property, plant and equipment costs are depreciated using straight-line methods over their estimated economic lives. Certain subsidiaries follow composite group depreciation methodology. Accordingly, when a portion of their depreciable property, plant and equipment is retired in the ordinary course of business, the gross book value is reclassified to accumulated depreciation, and no gain or loss is recognized on the disposition of these assets.

Property, plant and equipment is reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. We recognize an impairment loss when the carrying amount of a long-lived asset is not recoverable. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. (See Note 7)

The liability for the fair value of an asset retirement obligation is recorded in the period in which it is incurred if a reasonable estimate of fair value can be made. In periods subsequent to initial measurement, we recognize period-to-period changes in the

| Dollars in millions except per share amounts |

---

liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate. The increase in the carrying value of the associated long-lived asset is depreciated over the corresponding estimated economic life.

**Software Costs** We capitalize certain costs incurred in connection with developing or obtaining internal-use software. Capitalized software costs are included in "Property, Plant and Equipment – Net" on our consolidated balance sheets.

We amortize our capitalized software costs over a three-year to seven-year period, reflecting the estimated period during which these assets will remain in service.

**Goodwill and Other Intangible Assets** We have the following major classes of intangible assets: goodwill; licenses, which include Federal Communications Commission (FCC) and other wireless licenses; customer lists and relationships; and trademarks, trade names and various other finite-lived intangible assets (see Note 9).

Goodwill represents the excess of consideration paid over the fair value of identifiable net assets acquired in business combinations.

Wireless licenses provide us with the exclusive right to utilize certain radio frequency spectrum to provide wireless communications services. While wireless licenses are issued for a fixed period of time (generally 10 years), renewals of domestic wireless licenses have occurred routinely and at nominal cost. We have determined that there are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful lives of our FCC wireless licenses. Cash paid, including spectrum deposits (net of refunds), capitalized interest, and any payments for incentive and relocation costs are included in "Acquisitions, net of cash acquired" in our consolidated statements of cash flows. Interest is capitalized until the spectrum is ready for its intended use.

We amortize our wireless licenses in Mexico over their average remaining economic life of 25 years.

We acquired the rights to the AT&T and other trade names in previous acquisitions, classifying certain of those trade names as indefinite-lived. We have the effective ability to retain these exclusive rights permanently at a nominal cost.

Goodwill, FCC wireless licenses and other indefinite-lived intangible assets are not amortized but are tested at least annually for impairment (see Note 9). The testing for Goodwill and other indefinite-lived intangible assets is performed on the value as of October 1 each year and compares the book values of the assets to their fair values. Goodwill is tested by comparing the carrying amount of each reporting unit, deemed to be our principal operating segments or one level below them, to the fair value using both discounted cash flow as well as market multiple approaches. Trade names are tested by comparing their book values to their fair values calculated using a discounted cash flow approach on a presumed royalty rate derived from the revenues related to each brand name.

For FCC wireless licenses, we have the option to first perform a qualitative assessment to determine whether it is more likely than not that the book value exceeds their fair value. We consider several factors under the qualitative assessment, including macroeconomic conditions, industry and regulatory considerations, recent and projected performance of the business and the prior quantitative impairment testing results. On a periodic basis, or if the qualitative assessment indicates potential impairment, we perform a quantitative impairment test on the value as of October 1. FCC wireless licenses are tested on an aggregate basis, consistent with our use of the licenses on a national scope, using a discounted cash flow approach. We last performed a quantitative test in 2024.

Intangible assets that have finite useful lives are amortized over their estimated economic lives (see Note 9). Customer lists and relationships are amortized using primarily the sum-of-the-months-digits method of amortization over the period in which those relationships are expected to contribute to our future cash flows. Finite-lived trademarks and trade names are amortized using the straight-line method over the estimated useful life of the assets. The remaining finite-lived intangible assets are generally amortized using the straight-line method. These assets, along with other long-lived assets, are reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable.

**Advertising Costs** We expense advertising costs for products and services or for promoting our corporate image as incurred (see Note 23).

**Foreign Currency Translation** Our foreign subsidiaries and foreign investments generally report their earnings in their local currencies. We translate their foreign assets and liabilities at exchange rates in effect at the balance sheet dates. We translate their revenues and expenses using average rates during the year. The resulting foreign currency translation adjustments are recorded as a separate component of accumulated OCI on our consolidated balance sheets (see Note 3).

On April 5, 2023, we repurchased all of our Mobility preferred interests (see Note 16). For periods prior to repurchase, under ASU 2020-06, the ability to settle the Mobility preferred interests in stock was reflected in our diluted earnings per share calculation (see Note 1).

**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 have two reportable segments: Communications and Latin America.

Our chief operating decision maker (CODM) is our Chief Executive Officer and President. Our CODM uses operating income to evaluate performance and allocate resources, including capital allocations, when managing the business. Our CODM manages operations through the review of actual and forecasted "Operations and Support Expenses" information at a segment and business unit level, with Communications and Latin America segments primarily evaluated on a direct cost basis and comprised of equipment, compensation, network and technology, sales, advertising and other costs.

Additionally, business unit expenses within the Communications segment include direct and shared costs. Direct costs are incurred in support of products and services offered by the business units, such as equipment costs (predominantly wireless devices), network access, rents, leases, sales support, customer provisioning and commission expenses. Shared costs amongst the business units generally include information technology, network engineering and construction costs, advertising and other general and administrative expense.

The ***Communications segment*** provides wireless and wireline telecom and broadband services to consumers located in the United States 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, fixed wireless services, IP Voice and managed professional services, as well as legacy voice and data services and related equipment, to business customers.

• **Consumer Wireline** provides broadband services, including fiber connections that provide multi-gig services, and our fixed wireless access product (AT&T Internet Air or "AIA") that provides internet services delivered over our 5G wireless network, to residential customers in select locations. Consumer Wireline also provides legacy telephony voice communication services.

The ***Latin America segment*** provides wireless service 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. With the sale of our remaining interest in DIRECTV, we will no longer report these costs in 2026 (see Note 10).

• *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 17).

• *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.

**NOTE 5. REVENUE RECOGNITION**

We report our revenues net of sales taxes and record certain regulatory fees, primarily Universal Service Fund (USF) fees, on a net basis. No customer accounted for more than 10% of consolidated revenues in 2025, 2024 or 2023.

We offer service-only contracts and contracts that bundle equipment used to access the services and/or with other service offerings. Some contracts have fixed terms and others are cancelable on a short-term basis (i.e., month-to-month arrangements).

Examples of service revenues include wireless, fiber and other advanced connectivity, transitional and legacy voice and data. These services represent a series of distinct services that is considered a separate performance obligation. Service revenue is recognized when services are provided, based upon either period of time (e.g., monthly service fees) or usage (e.g., bytes of data processed).

Some of our services require customer premises equipment that, when combined and integrated with AT&T's specific network infrastructure, facilitates the delivery of service to the customer. In evaluating whether the equipment is a separate performance obligation, we consider the customer's ability to benefit from the equipment on its own or together with other readily available resources and if so, whether the service and equipment are separately identifiable (i.e., is the service highly dependent on, or highly interrelated with the equipment). When equipment is a separate performance obligation, we record the sale of equipment when title has passed and the products are accepted by the customer. For devices sold through indirect channels (e.g., national retailers), revenue is recognized when the retailer accepts the device, not upon activation.

Our equipment and service revenues are predominantly recognized on a gross basis, as most of our services do not involve a third party and we typically control the equipment that is sold to our customers.

Revenue recognized from fixed-term contracts that bundle services and/or equipment is allocated based on the standalone selling price of all required performance obligations of the contract (i.e., each item included in the bundle). Promotional discounts are attributed to each required component of the arrangement, resulting in recognition over the contract term. Standalone selling prices are determined by assessing prices paid for service-only contracts (e.g., arrangements where customers bring their own devices) and standalone device pricing.

We offer the majority of our customers the option to purchase certain wireless devices in installments over a specified period of time, and, in many cases, they may be eligible to trade in the original equipment for a new device and have the remaining unpaid balance paid or settled. For customers that elect these equipment installment payment programs, at the point of sale, we recognize revenue for the entire amount of revenue allocated to the customer receivable net of fair value of the trade-in right guarantee, when applicable. The difference between the revenue recognized and the consideration received is recorded as a note receivable when the devices are not discounted and our right to consideration is unconditional. When installment sales include promotional discounts that are earned by customers over the contract term (e.g., "buy one get one free" or equipment discounts with trade-in of a device), notes receivable are recognized net of discounts and the difference between revenue recognized and consideration received is recorded as a contract asset to be amortized over the contract term.

Less commonly, we offer certain customers highly discounted devices when they enter into a minimum service agreement term. For these contracts, we recognize equipment revenue at the point of sale based on a standalone selling price allocation. The difference between the revenue recognized and the cash received is recorded as a contract asset that will amortize over the contract term.

Our contracts allow for customers to frequently modify their arrangement, without incurring penalties in many cases. When a contract is modified, we evaluate the change in scope or price of the contract to determine if the modification should be treated as a new contract or if it should be considered a change of the existing contract. We generally do not have significant impacts from contract modifications.

Revenues from transactions between us and our customers are recorded net of revenue-based regulatory fees and taxes. Cash incentives given to customers are recorded as a reduction of revenue. Nonrefundable, upfront service activation and setup fees associated with service arrangements are deferred and recognized over the associated service contract period or customer relationship life.

**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 to five years.

**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 at December 31:

---

| | | |
|:---|:---|:---|
| ***Consolidated Balance Sheets*** | **2025** | 2024 |
| **Contract asset** | $**7816** | $6855 |
| &nbsp;&nbsp;&nbsp;&nbsp;Current portion in "Prepaid and other current assets" | **4131** | 3845 |
| **Contract liability** | **4409** | 4272 |
| &nbsp;&nbsp;&nbsp;&nbsp;Current portion in "Advanced billings and customer deposits" | **4136** | 3981 |

---

Our beginning of period contract liabilities recorded as customer contract revenue during 2025 was $3,981.

**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 December 31,

2025, the aggregate amount of the transaction price allocated to remaining performance obligations was $43,989, of which we expect to recognize approximately 88% by the end of 2027, with the balance recognized thereafter.

**NOTE 6. ACQUISITIONS, DISPOSITIONS AND OTHER ADJUSTMENTS**

**Spectrum Auctions** In February 2021, the FCC announced that AT&T was the winning bidder for 1,621 C-Band licenses, comprised of a total of 80 MHz nationwide, including 40 MHz in Phase I. We received the licenses in July 2021 and classified the auction deposits, related capitalized interest and billed relocation costs as "Licenses – Net" on our December 31, 2021 consolidated balance sheet. In December 2021, we paid $955 of Incentive Payments upon clearing of Phase I spectrum and paid $2,112 upon clearing of Phase II spectrum in 2023.

***Pending Acquisitions***

**Spectrum** On August 25, 2025, we agreed to purchase FCC licenses in the 600 MHz and 3.45 GHz bands from EchoStar Corporation for approximately $23,000, subject to certain adjustments. The transaction is expected to close in early 2026 and is subject to regulatory approval and other closing conditions. The FCC licenses will be used to expand our 5G network, meet future capacity demands and support future wireless communications services. We signed a short-term spectrum manager lease on the 3.45 GHz spectrum, which was deployed in cell sites covering nearly two-thirds of the U.S. population.

**Fiber** On May 21, 2025, we agreed to acquire substantially all of Lumen's Mass Markets fiber business for $5,750 cash, subject to purchase price adjustments. At the time of signing, the pending acquisition covered approximately one million fiber customers, and also included fiber network assets that reached more than four million fiber locations. On February 2, 2026, we completed the transaction and expect to manage the customer relationships in our Consumer Wireline business and place the fiber network assets in a new, wholly owned subsidiary. We plan to sell a controlling interest in the subsidiary to an equity partner that will co-invest in the ongoing business, and, as such, it is expected to meet the criteria for discontinued operations.

**NOTE 7. PROPERTY, PLANT AND EQUIPMENT**

Property, plant and equipment is summarized as follows at December 31:

---

Our depreciation expense was $20,746 in 2025, $20,421 in 2024 and $18,593 in 2023. Depreciation expense included amortization of software totaling $3,209 in 2025, $3,076 in 2024 and $3,023 in 2023.

In conjunction with the decommissioning of our copper-based legacy network, we retired approximately $16,600 of fully depreciated assets that were no longer in use. These assets were primarily related to our network and central offices.

**NOTE 8. LEASES**

We have operating and finance leases for certain facilities and equipment used in our operations. Our leases generally have remaining lease terms of up to 15 years. Some of our operating leases (e.g., for towers and real estate) contain renewal options that may be exercised, and some of our leases include options to terminate the leases within one year.

We have recognized a right-of-use asset for both operating and finance leases, and a corresponding lease liability that represents the present value of our obligation to make payments over the lease term. The present value of the lease payments is calculated using the incremental borrowing rate for operating and finance leases, which was determined using a portfolio approach based

------

---

| |
|:---|
| **AT&T Inc.** |
| Dollars in millions except per share amounts |

---

on the rate of interest that we would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. We use the unsecured borrowing rate and risk-adjust that rate to approximate a collateralized rate in the currency of the lease, which will be updated on a quarterly basis for measurement of new lease liabilities.

The components of lease expense were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **2025** | 2024 | 2023 |
| **Operating lease cost** | $**5927** | $5776 | $5577 |

**NOTE 9. GOODWILL AND OTHER INTANGIBLE ASSETS**

We test goodwill for impairment at a reporting unit level, which is deemed to be our principal operating segments or one level below, using the methodology described in Note 1. With our annual impairment testing as of October 1, the calculated fair value of each reporting unit exceeded its book value.

Changes to our goodwill in 2024 resulted from a third-quarter noncash goodwill impairment charge of $4,422 in our consolidated statements of income, which represented the entirety of our Business Wireline reporting unit goodwill. The decline in fair value was primarily due to the change in the long-term strategic plan of our Business Wireline reporting unit, which reflected lower long-term projected future cash flows associated with the industry-wide secular decline, including a faster-than-previously anticipated decline of legacy services.

Our Communications segment has three reporting units: Mobility, Consumer Wireline and Business Wireline. Business Wireline goodwill was fully impaired in 2024. The reporting unit is deemed to be the operating segment for Latin America and its goodwill was fully impaired in 2022. At December 31, 2025, accumulated goodwill impairments totaled $29,234.

The following table sets forth the changes in the carrying amounts of goodwill for the Communications segment:

| **Total** | $**63432** | $**(7)** | $**63425** | $67854 | $(4422) | $63432 |

---

We review amortizing intangible assets for impairment whenever events or circumstances indicate that the carrying amount may not be recoverable over the remaining life of the asset or asset group.

In 2025, we performed a qualitative impairment assessment, which indicated it was more likely than not that the fair value of our FCC wireless licenses exceeded the book value and did not result in an impairment. In 2024, we performed a quantitative impairment assessment, which reflected the fair value of our FCC wireless licenses exceeded their book value.

FCC wireless licenses increased in 2025 primarily due to spectrum acquisitions and capitalized interest. FCC wireless licenses increased in 2024 primarily due to compensable relocation and incentive payments and $199 of capitalized interest. (See Notes 6 and 23)

| Trade names | **5241** | 5241 |
| Total | $**130711** | $130316 |

---

Amortized intangible assets are definite-life assets, and, as such, we record amortization expense based on a method that most appropriately reflects our expected cash flows from these assets. Amortization expense for definite-life intangible assets was $140 for the year ended December 31, 2025, $159 for the year ended December 31, 2024 and $184 for the year ended December 31, 2023. Estimated amortization expense for the next five years is: $178 for 2026, $178 for 2027, $178 for 2028, $178 for 2029 and $176 for 2030.

**NOTE 10. EQUITY METHOD INVESTMENTS**

Investments in partnerships, joint ventures and less than majority-owned subsidiaries in which we have significant influence are accounted for under the equity method.

Our investments in equity affiliates at December 31, 2025, primarily included our interests in DriveNets and Gigapower. On July 2, 2025, we sold our interest in DIRECTV to TPG Capital (TPG).

**DIRECTV** Prior to its sale, we accounted for our investment in DIRECTV under the equity method of accounting. DIRECTV was considered a VIE for accounting purposes. As DIRECTV was jointly governed by a board with representation from both AT&T and TPG, with TPG having tie-breaking authority on certain key decisions, most significantly the appointment and removal of the CEO, we concluded that we were not the primary beneficiary of DIRECTV.

Our ownership interest in DIRECTV included $4,250 of junior preferred interests, an additional distribution preference of $4,200 and a 70% economic interest in common units.

In third-quarter 2024, our investment in DIRECTV was reduced to zero on our consolidated balance sheet, as a result of aggregate cash receipts exceeding our initial investment balance plus our cumulative equity in DIRECTV earnings. As we were not committed, implicitly or explicitly, to provide financial or other support to DIRECTV, we recorded cash distributions received in excess of our share of DIRECTV's earnings in "Equity in net income of affiliates" in the consolidated statements of income and as cash provided by operations in the consolidated statements of cash flows.

Prior to sale, during 2025, 2024 and 2023, we recognized $1,926, $2,027 and $1,666 of equity in net income of affiliates and received total distributions of $1,926, $2,955 and $3,715, respectively, from DIRECTV. The book value of our investment in DIRECTV was $0 at December 31, 2025 and 2024.

Upon the sale of our interests in DIRECTV in July 2025, we recorded a current note receivable of approximately $3,600 and a long-term receivable of $500. The disposition of DIRECTV also resulted in the release of approximately $2,900 of historical deferred tax liabilities. We recorded a gain on the sale of DIRECTV of approximately $5,600, which includes the impact of the transfer of deferred tax liabilities, indemnification liabilities and unfavorable contracts, in "Other income (expense) – net" in the

consolidated statements of income in 2025. As of December 31, 2025, we have received $3,100 of cash on the current note receivable, which was included in "Dispositions" in the consolidated statements of cash flows.

**DriveNets** We hold a 16.6% interest in DriveNets, which designs and builds high-scale networking solutions for service providers and AI infrastructures.

**Gigapower** We hold a 50% interest in our joint venture Gigapower, LLC (Gigapower), which provides a fiber network in select areas to internet service providers and other businesses across the United States.

**SKY Mexico** In June 2024, we sold our 41.3% interest in SKY Mexico, a leading pay-TV provider in Mexico.

On February 5, 2026, we issued $6,500 principal amount of global notes due 2031 to 2056 with a weighted average coupon of 5.2%. We intend to use the net proceeds from this issuance for general corporate purposes, which may include debt repayments and pending acquisitions.

**Credit Facilities**

*General* 

On November 3, 2025, we entered into (i) a $12,000 Second Amended and Restated Credit Agreement (Revolving Credit Agreement), with Citibank, N.A., as agent, amending and restating our existing $12,000 Amended and Restated Credit Agreement, dated as of November 18, 2022, and (ii) a $17,500 Delayed Draw Term Loan Credit Agreement (Term Loan), with Bank of America, N.A., as agent. No amount was outstanding under either the Revolving Credit Agreement or the Term Loan as of December 31, 2025.

The Revolving Credit Agreement and the Term Loan contain covenants that are customary for an issuer with investment grade senior debt credit ratings, including a net debt-to-EBITDA financial ratio covenant requiring us to maintain, as of the last day of each fiscal quarter, a ratio of not more than 3.75 to 1.

The events of default under the Revolving Credit Agreement and the Term Loan are customary for agreements of this type and such events would result in the acceleration of, or permit the requisite lenders to accelerate, as applicable, required payments under the relevant agreement and could increase the applicable margin under the relevant agreement by 2.00% per annum.

*Revolving Credit Agreement*

Advances under the Revolving Credit Agreement denominated in U.S. dollars will bear interest, at our option, either:

• at a variable annual rate equal to: (1) the highest of (but not less than zero) (a) the rate of interest announced publicly by Citibank in New York, New York, from time to time, as Citibank's base rate, (b) 0.5% per annum above the federal funds rate, and (c) the forward-looking term rate based on the secured overnight financing rate (Term SOFR) for a period of one

month plus 1.00%, plus (2) an applicable margin, as set forth in the Revolving Credit Agreement (Applicable Margin for Base Advances); or

• at a rate equal to: (i) Term SOFR for a period of one, three or six months, as applicable, plus (ii) an applicable margin, as set forth in the Revolving Credit Agreement (Applicable Margin for Benchmark Rate Revolving Advances).

Advances under the Revolving Credit Agreement denominated in Euro will bear interest at the Euro Interbank Offered Rate (EURIBOR) plus the Applicable Margin for Benchmark Rate Revolving Advances.

Advances under the Revolving Credit Agreement denominated in Sterling will bear interest at the Sterling Overnight Index Average (SONIA) plus the Applicable Margin for Benchmark Rate Revolving Advances.

The Applicable Margin for Benchmark Rate Revolving Advances will be equal to 0.690%, 0.805%, 0.920% or 1.045% per annum depending on our senior unsecured long-term debt ratings. The Applicable Margin for Base Rate Revolving Advances will be equal to the greater of (x) 0.00% and (y) the relevant Applicable Margin for Benchmark Rate Revolving Advances minus 1.00% per annum, depending on our senior unsecured long-term debt ratings.

We will also pay a facility fee of 0.06%, 0.07% or 0.08% per annum of the amount of the lender commitments, depending on AT&T's credit rating under the Revolving Credit Agreement.

The obligations of the lenders under the Revolving Credit Agreement to provide advances to us will terminate on November 3, 2030, unless the commitments are terminated in whole prior to that date. All advances must be repaid no later than the date on which lenders are no longer obligated to make any advances under the Revolving Credit Agreement.

The Revolving Credit Agreement provides that we and the lenders representing more than 50% of the facility amount may agree to extend their commitments under the Revolving Credit Agreement for two one-year periods beyond the initial termination date. We have the right to terminate, in whole or in part, amounts committed by the lenders under the Revolving Credit Agreement in excess of any outstanding advances; however, any such terminated commitments may not be reinstated.

The proceeds of the advances shall be solely for general corporate purposes.

*Delayed Draw Term Loan Credit Agreement*

The Term Loan is comprised of (i) a $6,000 364-day delayed draw term loan facility (364-Day Term Loan Facility) and (ii) a $11,500 two-year delayed draw term loan facility (Two-Year Term Loan Facility). Each of the 364-Day Term Loan Facility and Two-Year Term Loan Facility is available for a single draw at any time before November 3, 2026. The proceeds of the Term Loan will be used for general corporate purposes, which may include financing acquisitions of additional spectrum.

Advances will bear interest, at our option, either:

• at a variable annual rate (Base Rate) equal to: (1) the highest of (but not less than zero) (a) the prime rate quoted by Bank of America, N.A., (b) 0.5% per annum above the federal funds rate, and (c) the forward-looking SOFR term rate administered by the Chicago Mercantile Exchange (or any successor administrator) and published on the applicable Reuters screen page (or such other commercially available source providing such quotations) (Term SOFR Screen Rate) for a period of one month plus 1.00%, plus (2) an applicable margin, as set forth in the Term Loan (Applicable Margin for Base Rate Term Advances); or

• at a variable annual rate based upon Term SOFR (SOFR Rate) equal to: (1) the Term SOFR Screen Rate with a term equivalent to the applicable interest period of the advance plus (2) an applicable margin, as set forth in the Term Loan (Applicable Margin for SOFR Rate Term Advances).

The Applicable Margin for SOFR Rate Term Advances will be equal to 0.450%, 0.575%, 0.825%, 0.950% and 1.075% per annum for the 364-Day Term Loan Facility and 0.550%, 0.675%, 0.925%, 1.050% and 1.175% per annum for the Two-Year Term Loan Facility, in each case, depending on our senior unsecured long-term debt ratings. The Applicable Margin for Base Rate Term Advances under the Term Loan will be equal to the greater of (x) 0.00% and (y) the relevant Applicable Margin for SOFR Rate Term Advances minus 1.00% per annum, depending on our unsecured long-term debt ratings.

Commencing March 3, 2026, we will also pay a fee of 0.05%, 0.06%, 0.07%, 0.08% or 0.10% per annum of the amount of unused lender commitments, depending on our senior unsecured long-term debt ratings.

The Term Loan is not subject to amortization, and the entire principal amount of (i) the 364-Day Term Loan Facility will be due and payable 364 days after the date on which the borrowing is made and (ii) the Two-Year Term Loan Facility will be due and payable two years after the date on which the borrowing is made.

**NOTE 12. 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, 2024.

**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:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **December 31, 2025** | **December 31, 2025** | December 31, 2024 | December 31, 2024 |

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 December 31, 2025 and December 31, 2024. Derivatives designated as hedging instruments are reflected as "Prepaid and other current assets,"

**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:

---

| | | | |
|:---|:---|:---|:---|
| For the years ended December 31, | **2025** | 2024 | 2023 |
| Total gains (losses) recognized on equity securities | $**85** | $209 | $257 |
| Gains (losses) recognized on equity securities sold | **1** | (52) | 89 |
| Unrealized gains (losses) recognized on equity securities held at end of period | $**84** | $261 | $168 |

---

At December 31, 2025, available-for-sale debt securities totaling $587 have maturities as follows - less than one year: $13; one to three years: $125; three to five years: $183; five or more years: $266.

Our cash equivalents (money market securities) and short-term investments (certificate and time deposits) are recorded at amortized cost, and the respective carrying amounts approximate fair values. Short-term investments 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

------

---

| |
|:---|
| **AT&T Inc.** |
| Dollars in millions except per share amounts |

---

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 in 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 years ended December 31, 2025 and 2024, 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.

On September 30, 2022, we de-designated most of our cross-currency swaps from cash flow hedges and re-designated these swaps as fair value hedges. The amount remaining in accumulated other comprehensive loss related to cash flow hedges on the de-designation date was $1,857. The amount will be reclassified to earnings when the hedged item is recognized in earnings or when it becomes probable that the forecasted transactions will not occur. The election of fair value hedge designation for cross-currency swaps does not have an impact on our financial results.

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 December 31, 2025, we had posted collateral of $513 (a deposit asset) and held collateral of $314 (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 December, we would have been required to post additional collateral of $49. 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 $1,405. At December 31, 2024, we had posted collateral of $188 (a deposit asset) and held collateral of $0 (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.

**Nonrecurring Fair Value Measurements**

In addition to assets and liabilities that are recorded at fair value on a recurring basis, impairment indicators may subject goodwill and long-lived assets to nonrecurring fair value measurements. The implied fair values of the Business Wireline, Consumer Wireline and Mexico reporting units were estimated using both the discounted cash flow as well as market multiple approaches (see Note 9). The inputs to these models are considered Level 3.

**NOTE 13. INCOME TAXES**

Significant components of our deferred tax liabilities (assets) are as follows at December 31:

---

| | | |
|:---|:---|:---|
| | **2025** | 2024 |
| Depreciation and amortization | $**37570** | $36531 |
| Licenses and nonamortizable intangibles | **21742** | 20660 |

| Lease liabilities | **(5464)** | (5107) |
| Employee benefits | **(2585)** | (3017) |
| Deferred fulfillment costs | **1657** | 1788 |
| Equity in partnership | **14** | 2716 |
| Net operating loss and other carryforwards | **(5567)** | (5619) |

| Less: Noncurrent deferred tax assets | **(72)** | (80) |
| Net deferred tax liabilities | $**58240** | $58859 |

---

At December 31, 2025, we had combined net operating and capital loss carryforwards (tax effected) for federal income tax purposes of $695, state of $545 and foreign of $2,227, expiring through 2045. Additionally, we had federal credit carryforwards of $645 and state credit carryforwards of $1,454, expiring primarily through 2045.

We recognize a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. Our valuation allowances at December 31, 2025 and 2024 related primarily to state and foreign net operating losses and state credit carryforwards.

We consider post-1986 unremitted foreign earnings subjected to the one-time transition tax not to be indefinitely reinvested as such earnings can be repatriated without any significant incremental tax costs. We consider other types of unremitted foreign earnings to be indefinitely reinvested. U.S. income and foreign withholding taxes have not been recorded on temporary differences related to investments in certain foreign subsidiaries as such differences are considered indefinitely reinvested. The amount of unrecognized deferred tax liability does not have a material impact on the financial statements.

We recognize the financial statement effects of a tax return position when it is more likely than not, based on the technical merits, that the position will ultimately be sustained. For tax positions that meet this recognition threshold, we apply our judgment, taking into account applicable tax laws, our experience in managing tax audits and relevant GAAP, to determine the amount of tax benefits to recognize in our financial statements. For each position, the difference between the benefit realized on our tax return and the benefit reflected in our financial statements is recorded on our consolidated balance sheets as an unrecognized tax benefit (UTB). We update our UTBs at each financial statement date to reflect the impacts of audit settlements and other resolutions of audit issues, the expiration of statutes of limitation, developments in tax law and ongoing discussions with taxing authorities.

Periodically we make deposits to taxing jurisdictions which reduce our UTB balance but are not included in the reconciliation above. The amount of deposits that reduced our UTB balance was $2,894 at December 31, 2025, $2,282 at December 31, 2024 and $2,361 at December 31, 2023. Current tax assets on our consolidated balance sheets were $2,772 at December 31, 2025, $2,236 at December 31, 2024 and $2,079 at December 31, 2023.

Accrued interest and penalties included in UTBs were $2,604 as of December 31, 2025, $2,223 as of December 31, 2024 and $1,785 as of December 31, 2023. We record interest and penalties related to federal, state and foreign UTBs in income tax expense. The net interest and penalty expense included in income tax expense was $476 for 2025, $474 for 2024 and $324 for 2023.

We file income tax returns in the U.S. federal jurisdiction and various state, local and foreign jurisdictions. As a large taxpayer, our income tax returns are regularly audited by the Internal Revenue Service (IRS) and other taxing authorities.

The IRS has completed field examinations of our tax returns through 2015. All audit periods prior to 2006 are closed for federal examination purposes, and we have effectively resolved all outstanding audit issues for years through 2010 with the IRS Appeals Division.

The components of income tax expense (benefit) are as follows:

**NOTE 14. PENSION AND POSTRETIREMENT BENEFITS**

We offer noncontributory pension programs covering the majority of domestic nonmanagement employees in our Communications business. Nonmanagement employees' pension benefits are generally calculated using one of two formulas: a flat dollar amount applied to years of service according to job classification, or a cash balance plan with negotiated annual pension band credits as well as interest credits. Most employees can elect to receive their pension benefits in either a lump sum payment or an annuity.

Pension programs covering U.S. management employees are closed to new entrants. These programs continue to provide benefits to participants that were generally hired before January 1, 2015, who receive benefits under either cash balance pension programs that include annual or monthly credits based on salary as well as interest credits, or a traditional pension formula (i.e., a stated percentage of employees' adjusted career income).

We also provide a variety of medical, dental and life insurance benefits to certain retired employees under various plans and accrue actuarially determined postretirement benefit costs as active employees earn these benefits.

In 2023, AT&T and State Street Global Advisors Trust Company, as independent fiduciary of the AT&T Pension Benefit Plan (Plan), entered into a commitment agreement with subsidiaries of Athene Holding Ltd. (Athene) under which AT&T agreed to purchase nonparticipating single premium group annuity contracts that would transfer to Athene $8,067 of the Plan's defined benefit pension obligations related to certain retirees, participants and beneficiaries under the Plan. This transaction with Athene was considered a settlement for accounting purposes and required us to remeasure our pension plan assets and obligations at quarter-end for the second and third quarters of 2023.

**Obligations and Funded Status**

For defined benefit pension plans, the benefit obligation is the projected benefit obligation, the actuarial present value, as of our December 31 measurement date, of all benefits attributed by the pension benefit formula to employee service rendered to that date. The amount of benefit to be paid depends on a number of future events incorporated into the pension benefit formula, including estimates of the average life of employees and their beneficiaries and average years of service rendered. It is measured based on assumptions concerning future interest rates and future employee compensation levels as applicable.

For postretirement benefit plans, the benefit obligation is the accumulated postretirement benefit obligation, the actuarial present value as of the measurement date of all future benefits attributed under the terms of the postretirement benefit plans to employee service.

The following table presents the change in the projected benefit obligation for the years ended December 31:

---

|:---|:---|:---|:---|:---|

We recognize gains and losses on pension and postretirement plan assets and obligations immediately in "Other income (expense) – net" in our consolidated statements of income. These gains and losses are generally measured annually as of December 31 and accordingly, will normally be recorded during the fourth quarter, unless an earlier remeasurement is required. Should actual experience differ from actuarial assumptions, the projected pension benefit obligation and net pension cost and accumulated postretirement benefit obligation and postretirement benefit cost would be affected in future years.

*Discount Rate* Our assumed weighted-average discount rates for pension and postretirement benefits of 5.50% and 5.30% respectively, at December 31, 2025, reflect the hypothetical rate at which the projected benefit obligation could be effectively settled or paid out to participants. We determined our discount rates based on a range of factors, including a yield curve composed of the rates of return on several hundred high-quality, fixed income corporate bonds available at the measurement date and corresponding to the related expected durations of future cash outflows. These bonds had an average rating of at least Aa3 or AA- by the nationally recognized statistical rating organizations, denominated in U.S. dollars, and generally not callable, convertible or index linked. For the year ended December 31, 2025, when compared to the year ended December 31, 2024, we decreased our pension discount rate by 0.20%, resulting in an increase in our pension plan benefit obligation of $680, and decreased our postretirement discount rate by 0.30%, resulting in an increase in our postretirement benefit obligation of $167. For the year ended December 31, 2024, when compared to the year ended December 31, 2023, we increased our pension

discount rate by 0.70%, resulting in a decrease in our pension plan benefit obligation of $1,994, and increased our postretirement discount rate by 0.60%, resulting in a decrease in our postretirement benefit obligation of $317.

We utilize a full yield curve approach in the estimation of the service and interest components of net periodic benefit costs for pension and other postretirement benefits. Under this approach, we apply discounting using individual spot rates from a yield curve composed of the rates of return on several hundred high-quality, fixed income corporate bonds available at the measurement date. These spot rates align to each of the projected benefit obligations and service cost cash flows. The service cost component relates to the active participants in the plan, so the relevant cash flows on which to apply the yield curve are considerably longer in duration on average than the total projected benefit obligation cash flows, which also include benefit payments to retirees. Interest cost is computed by multiplying each spot rate by the corresponding discounted projected benefit obligation cash flows. The full yield curve approach reduces any actuarial gains and losses based upon interest rate expectations (e.g., built-in gains in interest cost in an upward-sloping yield curve scenario), or gains and losses merely resulting from the timing and magnitude of cash outflows associated with our benefit obligations. Neither the annual measurement of our total benefit obligations nor annual net benefit cost is affected by the full yield curve approach.

*Expected Long-Term Rate of Return* In 2026, our expected long-term rate of return is 7.75% on pension plan assets and 4.00% on postretirement plan assets. Our long-term rates of return reflect the average rate of earnings expected on the funds invested, or to be invested, to provide for the benefits included in the projected benefit obligations. In setting the long-term assumed rate of return, management considers capital markets' future expectations, the asset mix of the plans' investment and average historical asset return. Actual long-term returns can, in relatively stable markets, also serve as a factor in determining future expectations. We consider many factors that include, but are not limited to, historical returns on plan assets, current market information on long-term returns (e.g., long-term bond rates) and current and target asset allocations between asset categories. The target asset allocation is determined based on consultations with external investment advisers. If all other factors were to remain unchanged, we expect that a 0.50% decrease in the expected long-term rate of return would cause 2026 combined pension and postretirement cost to increase $139. However, any differences in the rate and actual returns will be included with the actuarial gain or loss recorded in the fourth quarter when our plans are remeasured.

*Composite Rate of Compensation Increase* Our expected composite rate of compensation increase cost of 3.00% in 2025 and 2024 reflects the long-term average rate of salary increases.

*Healthcare Cost Trend* Our healthcare cost trend assumptions are developed based on historical cost data, the near-term outlook and an assessment of likely long-term trends. Based on our assessment of expectations of healthcare industry inflation, our 2026 assumed annual healthcare prescription drug cost trend and medical cost trend for eligible participants is 8.25%, grading down to an ultimate trend rate of 4.25% in 2035. For 2025, our assumed annual healthcare prescription drug cost trend and medical cost trend for eligible participants was 8.25%, grading down to an ultimate trend rate of 4.25% in 2032.

**Plan Assets**

Plan assets consist primarily of private and public equity, government and corporate bonds, and real assets (real estate and natural resources). The asset allocations of the pension plans are maintained to meet ERISA requirements. Any plan contributions, as determined by ERISA regulations, are made to a pension trust for the benefit of plan participants. We do not have significant ERISA required contributions to our pension plans for 2026. We voluntarily contributed $1,150 to our pension plans during 2025, and intend to voluntarily contribute $350 during 2026.

We maintain VEBA trusts to partially fund postretirement benefits; however, there are no ERISA or regulatory requirements that these postretirement benefit plans be funded annually.

The principal investment objectives are to ensure the availability of funds to pay pension and postretirement benefits as they become due under a broad range of future economic scenarios, maximize long-term investment return with an acceptable level of risk based on our pension and postretirement obligations, and diversify broadly across and within the capital markets to insulate asset values against adverse experience in any one market. Each asset class has broadly diversified characteristics. Substantial biases toward any particular investing style or type of security are sought to be avoided by managing the aggregation of all accounts with portfolio benchmarks. Asset and benefit obligation forecasting studies are conducted periodically, generally every two to three years, or when significant changes have occurred in market conditions, benefits, participant demographics or funded status. Decisions regarding investment policy are made with an understanding of the effect of asset allocation on funded status, future contributions and projected expenses. During 2025, the pension trust entered into a series of derivative contracts as part of an additional interest rate hedging strategy. This hedging strategy better aligns the pension asset duration with the liability duration and improves the interest rate hedge ratio. The notional amount of the contracts was approximately $7,300 as of December 31, 2025.

At December 31, 2025, AT&T securities represented less than 1% of assets held by our pension trust. The VEBA trusts do not hold AT&T securities.

*Investment Valuation*

Investments are stated at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability at the measurement date.

Investments in securities traded on a national securities exchange are valued at the last reported sales price on the final business day of the year. If no sale was reported on that date, they are valued at the last reported bid price. Investments in securities not traded on a national securities exchange are valued using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Shares of registered investment companies are valued based on quoted market prices, which represent the net asset value of shares held at year-end.

Other commingled investment entities are valued at quoted redemption values that represent the net asset values of units held at year-end, which management has determined approximates fair value.

Real estate and natural resource direct investments are valued at amounts based upon appraisal reports. Fixed income securities valuation is based upon observable prices for comparable assets, broker/dealer quotes (spreads or prices), or a pricing matrix that derives spreads for each bond based on external market data, including the current credit rating for the bonds, credit spreads to Treasuries for each credit rating, sector add-ons or credits, issue-specific add-ons or credits as well as call or other options.

Purchases and sales of securities are recorded as of the trade date. Realized gains and losses on sales of securities are determined on the basis of average cost. Interest income is recognized on the accrual basis. Dividend income is recognized on the ex-dividend date.

Non-interest bearing cash and overdrafts are valued at cost, which approximates fair value.

*Fair Value Measurements*

**Estimated Future Benefit Payments**

Expected benefit payments are estimated using the same assumptions used in determining our benefit obligation at December 31, 2025. Because benefit payments will depend on future employment and compensation levels; average years employed; average life spans; and payment elections, among other factors, changes in any of these assumptions could significantly affect these expected amounts. The following table provides expected benefit payments under our pension and postretirement plans:

---

| | | |
|:---|:---|:---|
| | Pension Benefits | Postretirement Benefits |
| 2026 | $3460 | $664 |
| 2027 | 2955 | 641 |
| 2028 | 2893 | 623 |
| 2029 | 2830 | 520 |
| 2030 | 2765 | 538 |
| Years 2031 - 2035 | 12516 | 2536 |

**Supplemental Retirement Plans**

We also provide certain senior- and middle-management employees with nonqualified, unfunded supplemental retirement and savings plans. While these plans are unfunded, we have assets in a designated non-bankruptcy remote trust that are independently managed and used to provide for certain of these benefits. These plans include supplemental pension benefits as well as compensation-deferral plans, some of which include a corresponding match by us based on a percentage of the compensation deferral. For our supplemental retirement plans, the projected benefit obligation was $1,199 and the net supplemental retirement pension cost was $92 at and for the year ended December 31, 2025. The projected benefit obligation was $1,305 and the net supplemental retirement pension cost was $18 at and for the year ended December 31, 2024.

We use the same significant assumptions for the composite rate of compensation increase in determining our projected benefit obligation and the net pension and postemployment benefit cost. Our discount rates of 5.10% at December 31, 2025 and 5.50% at December 31, 2024 were calculated using the same methodologies used in calculating the discount rates for our qualified pension and postretirement benefit plans.

Deferred compensation expense was $96 in 2025, $152 in 2024 and $101 in 2023.

**Contributory Savings Plans**

We maintain contributory savings plans that cover substantially all employees. Under the savings plans, we match in cash or company stock a stated percentage of eligible employee contributions, subject to a specified ceiling. There are no debt-financed shares held by the Employee Stock Ownership Plans, allocated or unallocated.

Our match of employee contributions to the savings plans is fulfilled with purchases of our stock on the open market or company cash. Benefit cost, which is based on the cost of shares or units allocated to participating employees' accounts or the cash contributed to participant accounts, was $546, $565 and $570 for the years ended December 31, 2025, 2024 and 2023.

**NOTE 15. SHARE-BASED COMPENSATION**

Under our various share-based compensation plans, senior and other management employees and nonemployee directors have received performance stock units and other nonvested stock units.

As of December 31, 2025, we were authorized to issue up to approximately 41 million shares of common stock (including shares that may be issued upon exercise of outstanding options or upon vesting of performance stock units or other nonvested stock units) pursuant to these various plans:

• Performance stock units, which are nonvested stock units, which are valued based upon the market price of our common stock at the date of grant and performance expectations. These distribute in the form of AT&T common stock and cash at the end of a three-year period, subject to the achievement of certain performance goals. We treat the cash-settled portion of these awards as a liability.

• Restricted stock and restricted stock units are valued at the market price of our common stock at the date of grant and do not have any performance conditions. Restricted stock predominantly vests over a three- to ten-year period and restricted stock units predominantly vest over a three-year period.

We account for our share-based compensation arrangements based on the fair value of the awards on their respective grant date, which may affect our ability to fully realize the value shown on our consolidated balance sheets of deferred tax assets associated with compensation expense. We record a valuation allowance when our future taxable income is not expected to be sufficient to recover the asset. Accordingly, there can be no assurance that the current stock price of our common shares will rise to levels sufficient to realize the entire tax benefit currently reflected on our consolidated balance sheets. However, to the extent we generate excess tax benefits (i.e., those additional tax benefits in excess of the deferred taxes associated with compensation expense previously recognized) the potential future impact on income would be reduced.

Our consolidated statements of income include the share-based compensation cost recognized for the plans described above as "Selling, general and administrative" expense. Those expenses, as well as the associated tax benefits, are reflected in the table below:

---

| | | | |
|:---|:---|:---|:---|
| | **2025** | 2024 | 2023 |
| Performance stock units | $**152** | $127 | $79 |
| Restricted stock and stock units | **384** | 378 | 400 |
| Total | $**536** | $505 | $479 |
| Income tax benefit | $**130** | $123 | $118 |

As of December 31, 2025, there was $584 of total unrecognized compensation cost related to nonvested share-based compensation arrangements outstanding. That cost is expected to be recognized over a weighted-average period of 1.89 years. The total fair value of shares vested during the year was $464 for 2025, compared to $452 for 2024 and $592 for 2023.

**NOTE 16. STOCKHOLDERS' AND MEZZANINE EQUITY**

**Authorized Shares** We have authorized 14 billion common shares of AT&T stock and 10 million preferred shares of AT&T stock, each with a par value of $1.00 per share. Cumulative perpetual preferred shares consist of the following:

• Series A: 48 thousand shares outstanding at December 31, 2025 and December 31, 2024, with a $25,000 per share liquidation preference and a dividend rate of 5.000%.

• Series B: no shares outstanding at December 31, 2025 and 20 thousand shares outstanding at December 31, 2024, with a €100,000 per share liquidation preference, and an initial rate of 2.875%. We redeemed all outstanding Series B cumulative preferred shares on March 3, 2025. The shares had a total liquidation preference of €2.0 billion and were redeemed for $2,075.

• Series C: 70 thousand shares outstanding at December 31, 2025 and December 31, 2024, with a $25,000 per share liquidation preference, and a dividend rate of 4.75%.

So long as the quarterly preferred dividends are declared and paid on a timely basis on each series of preferred shares, there are no limitations on our ability to declare a dividend on or repurchase AT&T common shares. The preferred shares are optionally redeemable by AT&T at the liquidation price on or after five years from the issuance date, or upon certain other contingent events.

**Stock Repurchase Program** From time to time, we repurchase shares of common stock. Over the past few years, these repurchases have generally been for distribution through our employee benefit plans or in connection with certain acquisitions. In December 2024, the Board approved an authorization to repurchase up to $10,000 of common stock (the "2024 Authorization") and terminated the March 2014 authorization. During 2025, we repurchased approximately 159 million shares totaling $4,269 under this authorization, excluding brokerage fees and the one percent excise tax imposed by the Inflation Reduction Act of 2022. On January 27, 2026, the Board approved an authorization to repurchase an additional $10,000 of common stock (the "2026 Authorization").

To implement repurchase authorizations, we have used open market repurchases, relying on Rule 10b5-1 of the Securities Exchange Act of 1934, where feasible. We have also used accelerated share repurchase agreements with large financial institutions to repurchase our stock. During 2024, we repurchased approximately 36 thousand shares totaling $1 under the March 2014 authorization.

**Dividend Declarations** In December 2025 and December 2024, AT&T declared a quarterly preferred dividend of $36. In December 2025 and December 2024, AT&T declared a quarterly common dividend of $0.2775 per share of common stock.

**Preferred Interests Issued by Subsidiaries** We have issued cumulative perpetual preferred membership interests in certain subsidiaries. The preferred interests are entitled to cash distributions, subject to declaration.

*Mobility II Preferred Interests* 

In 2018, we issued 320 million Series A Cumulative Perpetual Preferred Membership Interests in Mobility II (Mobility preferred interests), which paid cash distributions of 7% per annum, subject to declaration. So long as the distributions were declared and paid, the terms of the Mobility preferred interests did not impose any limitations on cash movements between affiliates, or our ability to declare a dividend on or repurchase AT&T shares. All Mobility preferred interests were repurchased as of April 2023.

Prior to repurchase, a holder of the Mobility preferred interests could put the interests to Mobility II, or Mobility II could have redeemed the interests upon a change in control of Mobility II or on or after September 9, 2022, with either option only allowed to be exercised during certain periods. The redemption price was to be paid with cash, AT&T common stock, or a combination of cash and AT&T common stock, at Mobility II's sole election.

*Tower Holdings Preferred Interests*

In 2019, we issued $6,000 nonconvertible cumulative preferred interests in a wireless subsidiary (Tower Holdings) that holds interests in various tower assets and has the right to receive approximately $6,000 if the purchase options from the tower companies are exercised.

The membership interests in Tower Holdings consist of (1) common interests, which are held by a consolidated subsidiary of AT&T, and (2) two series of preferred interests (collectively the "2019 Tower preferred interests"). The 2019 Tower preferred

interests were subject to reset in December 2024 and included a September series (Tower Class A-1) totaling $1,500 that paid an initial preferred distribution of 5.0%, and a December series (Tower Class A-2) totaling $4,500 that paid an initial preferred distribution of 4.75%.

In August 2024, we amended the 2019 Tower preferred interests, effective November 2024, to reset the rate and restructure the membership interests whereby all of the 2019 Tower preferred interests are now designated Fixed Rate Class A Limited Membership Interests (Tower Fixed Rate Interests). A portion of the Tower Fixed Rate Interests will move to Floating Rate Class A Limited Membership Interests (Tower Floating Rate Interests) each year over a five-year period. The Tower Fixed Rate Interests pay a preferred distribution of 5.90%, and the Tower Floating Rate Interests pay a preferred distribution equal to the Secured Overnight Financing Rate (SOFR) plus 250 basis points, as defined in the agreement. Distributions are paid quarterly, subject to declaration, and reset every five years. Any failure to declare or pay distributions on the Tower Fixed Rate Interests or Tower Floating Rate Interests (collectively, the "Tower preferred interests") would not impose any limitation on cash movements between affiliates, or our ability to declare a dividend on or repurchase AT&T shares. We can call the Tower preferred interests at the issue price beginning in November 2029, and we can call the Tower Floating Rate Interests at any time. We redeemed $65 of the Tower Floating Rate Interests in November 2025. If not called, the remaining Tower Floating Rate Interests could equal $460 by 2028. The Tower preferred interests are included in "Noncontrolling interest" on the consolidated balance sheets.

The holders of the Tower preferred interests have the option to require redemption upon the occurrence of certain contingent events, such as the failure of AT&T to pay the preferred distribution for two or more periods or to meet certain other requirements, including a minimum credit rating. If notice is given upon such an event, all other holders of equal or more subordinate classes of membership interests in Tower Holdings are entitled to receive the same form of consideration payable to the holders of the preferred interests, resulting in a deemed liquidation for accounting purposes.

*Telco LLC Preferred Interests*

In September 2020, we issued $2,000 nonconvertible cumulative preferred interests (Telco Class A-1) out of a newly created limited liability company (Telco LLC) that was formed to hold telecommunications-related assets. In April 2023, we expanded our September 2020 transaction and issued an additional $5,250 of nonconvertible cumulative preferred interests (Telco Class A-2 and A-3). In March 2025, we issued an additional $2,250 of nonconvertible cumulative preferred interests in Telco LLC (Telco Class A-4). The Telco Class A-4 interests will pay an initial preferred distribution of 5.94% annually, subject to declaration, and subject to reset on November 1, 2028, and every four years thereafter. The Telco Class A-4 interests can be called at issue price beginning on November 1, 2028, and are subject to the same redemption and liquidation rights as the Telco Class A-1, A-2 and A-3 interests. As of December 31, 2025 and 2024, cumulative preferred interests in our Telco LLC totaled $9,500 and $7,250 (collectively the "Telco preferred interests").

Members' equity in Telco LLC consists of (1) members' interests, which are held by a consolidated subsidiary of AT&T, (2) Telco Class A-1 preferred interests, which pay an initial preferred distribution of 4.25% annually, subject to declaration, and subject to reset every seven years, and (3) Telco Class A-2 and A-3 preferred interests, which pay an initial preferred distribution of 6.85% annually, subject to declaration, and subject to reset on November 1, 2027, and every seven years thereafter. Failure to pay distributions on the Telco preferred interests would not limit cash movements between affiliates, or our ability to declare a dividend on or repurchase AT&T shares. We can call the Telco preferred interests at the issue price beginning seven years from the issuance date. The Telco preferred interests are included in "Noncontrolling interest" on the consolidated balance sheets.

The holders of the Telco preferred interests have the option to require redemption upon the occurrence of certain contingent events, such as the failure of Telco LLC to pay the preferred distribution for two or more periods or to meet certain other requirements, including a minimum credit rating. If notice is given, all other holders of equal or more subordinate classes of members' equity are entitled to receive the same form of consideration payable to the holders of the preferred interests, resulting in a deemed liquidation for accounting purposes.

*Mobility II Redeemable Noncontrolling Interests*

In June 2023, we issued two million Series B Cumulative Perpetual Preferred Membership Interests in Mobility II LLC (Mobility noncontrolling interests), which pay cash distributions of 6.8% per annum, subject to declaration. So long as the distributions are declared and paid, the terms of the Mobility noncontrolling interests will not impose any limitations on cash movements between affiliates, or our ability to declare a dividend on or repurchase AT&T shares.

The Mobility noncontrolling interests are required to be initially recorded at fair value less issuance costs and will accrete to redemption value of $2,000 through "Net Income Attributable to Noncontrolling Interest." The Mobility noncontrolling interests are considered Level 3 under the Fair Value Measurement and Disclosures framework (see Note 12) and included in "Redeemable Noncontrolling Interest" on the consolidated balance sheets.

A holder of the Mobility noncontrolling interests may put the interests to Mobility II on or after the earliest of certain events or each June 15 and December 15, beginning on June 15, 2028. Mobility II may redeem the interests on each March 15 and September 15, beginning on March 15, 2028. The price at which a put option or a redemption option can be exercised is the sum of (a) $1,000 per Mobility noncontrolling interest plus (b) any accrued and unpaid distributions. The redemption price must be paid in cash.

**NOTE 17. 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 for the years ended December 31:

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 at December 31:

**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.

------

| **AT&T Inc.** |
| Dollars in millions except per share amounts |

---

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:

---

| | | | |
|:---|:---|:---|:---|
| | **2025** | 2024 | 2023 |
| Gross receivables sold<sup>1</sup> | $**12513** | $10696 | $11104 |

---

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 12).

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

---

| | | | |
|:---|:---|:---|:---|
| | **2025** | 2024 | 2023 |

At December 31, 2025 and December 31, 2024, our beneficial interests were $2,067 and $3,185, respectively, of which $1,338 and $1,906 are included in "Prepaid and other current assets" on our consolidated balance sheets, with the remainder in "Other Assets." The guarantee obligation at December 31, 2025 and December 31, 2024 was $410 and $301, respectively, of which $216 and $150 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 2025, we expanded our revolving agreement to transfer up to $2,940 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 $425 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.

**NOTE 18. TOWER TRANSACTION**

In December 2013, we closed our transaction with Crown Castle International Corp. (Crown Castle) in which Crown Castle gained the exclusive rights to lease and operate 9,048 wireless towers and purchased 627 of our wireless towers for $4,827 in cash. The leases have various terms with an average length of approximately 28 years. As the leases expire, Crown Castle will have fixed price purchase options for these towers totaling approximately $4,200, based on their estimated fair market values at the end of the lease terms. We are subleasing space on the towers from Crown Castle over an estimated original term of 20 years, at current market rates, subject to further optional renewals in the future.

We determined that we did not transfer control of the tower assets, which prevented us from achieving sale-leaseback accounting for the transaction, and we accounted for the cash proceeds from Crown Castle as a financing obligation on our consolidated balance sheets. We record interest on the financing obligation using the effective interest method at a rate of approximately 3.9%. The financing obligation is increased by interest expense and estimated future net cash flows generated and retained by Crown Castle from operation of the tower sites, and reduced by our contractual payments. We continue to include the tower assets in "Property, Plant and Equipment – Net" on our consolidated balance sheets and depreciate them accordingly. At December 31, 2025 and 2024, the tower assets had a balance of $569 and $608, respectively. Our depreciation expense for these assets was $39 for each of 2025, 2024 and 2023.

Payments made to Crown Castle under this arrangement were $274 for 2025. At December 31, 2025, the future minimum payments under the sublease arrangement are $280 for 2026, $285 for 2027, $291 for 2028, $297 for 2029, $303 for 2030 and $1,086 thereafter.

**NOTE 19. TRANSACTIONS WITH DIRECTV**

Prior to its sale, we accounted for our investment in DIRECTV under the equity method and recorded our share of DIRECTV earnings as equity in net income of affiliates, with DIRECTV considered a related party. On July 2, 2025, we sold our interest in DIRECTV to TPG. (See Note 10)

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:

---

| | | | |
|:---|:---|:---|:---|
| | **2025** | 2024 | 2023 |
| DIRECTV's earnings included in Equity in net income of affiliates | $**1926** | $2027 | $1666 |
| Distributions classified as operating activities | $**1926** | $2027 | $1666 |
| Distributions classified as investing activities | **—** | 928 | 2049 |
| Cash distributions received from DIRECTV | $**1926** | $2955 | $3715 |

---

For the years ended December 31, 2025, 2024 and 2023, we billed DIRECTV approximately $240, $536 and $730 under commercial arrangements and transition service agreements, which were recorded as a reduction to the operations and support expenses incurred.

**NOTE 20. FIRSTNET**

In 2017, the First Responder Network Authority (FirstNet) selected AT&T to build and manage the first nationwide broadband network dedicated to America's first responders. Under the 25-year agreement, FirstNet provides 20 MHz of valuable telecommunications spectrum and success-based payments of $6,500 to support network buildout, which has been substantially completed. We are required to construct a network that achieves coverage and nationwide interoperability requirements and have a contractual commitment to make sustainability payments of $18,000 over the 25-year contract. These sustainability payments represent our commitment to fund FirstNet's operating expenses and future reinvestments in the network which we own and operate, which we estimate in the $3,000 or less range over the life of the 25-year contract. After FirstNet's operating expenses are paid, we anticipate the remaining amount, expected to be in the $15,000 range, will be reinvested into the network. On January 30, 2024, FirstNet agreed to reinvest up to $6,300 in the network over 10 years, subject to authorization.

During 2025, we submitted $420 in sustainability payments, with future payments under the agreement of $896 for 2026, $1,566 for 2027, $1,658 for 2028, $1,474 for 2029, $1,115 for 2030, and $9,320 thereafter. Amounts paid to FirstNet, which are not expected to be returned to AT&T to be reinvested into our network, will be expensed in the period paid. In the event FirstNet does not reinvest any funds to construct, operate, improve and maintain this network, our maximum exposure to loss is the total amount of the sustainability payments, which would be reflected in higher expense.

**NOTE 21. CONTINGENT LIABILITIES** 

We are party to numerous lawsuits, regulatory proceedings and other matters arising in the ordinary course of business. In evaluating these matters on an ongoing basis, we take into account amounts already accrued on the balance sheet. In our opinion, although the outcomes of these proceedings are uncertain, they should not have a material adverse effect on our financial position, results of operations or cash flows. See Note 12 for a discussion of collateral and credit-risk contingencies.

We have contractual obligations to purchase certain goods or services from various other parties. Our purchase obligations are expected to be approximately $8,545 in 2026, $10,698 in total for 2027 and 2028, $2,505 in total for 2029 and 2030 and $2,890 in total for years thereafter.

**NOTE 22. 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 to 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.

Our outstanding payment obligations are included in "Accounts payable and accrued liabilities" on our consolidated balance sheets and are reported as operating or investing (when capitalizable) activities in our statements of cash flows when paid.

The following table presents the change in the supplier financing obligation for the years ended December 31:

---

| | | |
|:---|:---|:---|
| | **2025** | 2024 |
| Confirmed obligations outstanding at the beginning of year | $**2498** | $2844 |
| Invoices received | **17939** | 15510 |

**Direct Supplier Financing**

We also have arrangements with suppliers of handset inventory that allow us to extend the stated payment terms by generally 90 days at an additional cost to us (variable rate extension fee). Direct supplier financing outstanding is included in "Accounts payable and accrued liabilities" on our consolidated balance sheets and is reported as operating activities in our statements of cash flows when paid.

The following table presents the change in the direct supplier financing obligation for the years ended December 31:

**DESCRIPTION OF THE COMPANY'S COMMON STOCK**

*The following summary of AT&T Inc.'s ("AT&T") common stock is based on and qualified by the Company's Restated Certificate of Incorporation and Bylaws as of December 31, 2025. For a complete description of the terms and provisions of the Company's equity securities, including its common stock, refer to the Restated Certificate of Incorporation and the Bylaws, both of which are filed as exhibits to AT&T's Annual Report on Form 10-K for the year ended December 31, 2025. Throughout this exhibit, references to "we," "our," "us" and "the Company" refer to AT&T.*

**General**

Our authorized share capital consists of 14,010,000,000 shares, of which 14,000,000,000 are common shares having a par value of $1.00 per share and 10,000,000 are shares of preferred stock, par value $1.00 per share. As of December 31, 2025, 7,037,495,711 shares of common stock were outstanding and 118,000 shares of preferred stock were outstanding.

Our common stock is listed on the New York Stock Exchange and NYSE Texas under the symbol "T".

------

The transfer agent for the common stock is Computershare Trust Company, N.A., P.O. Box 505005, Louisville, Kentucky 40233.

We typically do not issue physical stock certificates. Instead, we record evidence of stock ownership solely on our corporate records. However, we will issue a physical stock certificate if a stockholder so requests.

Holders of common stock do not have any conversion, redemption, preemptive or cumulative voting rights. In the event of our dissolution, liquidation or winding-up, common stockholders share ratably in any assets remaining after all creditors are paid in full, including holders of our debt securities and after the liquidation preference of holders of preferred stock has been satisfied.

Some of the provisions of our Restated Certificate of Incorporation and our Bylaws may tend to deter any potential unfriendly tender offers or other efforts to obtain control of us. At the same time, these provisions will tend to assure continuity of management and corporate policies and to induce any persons seeking control or a business combination with us to negotiate on terms acceptable to our then-elected board of directors.

**Dividends**

Common stockholders are entitled to participate equally in dividends when dividends are declared by our board of directors out of funds legally available for dividends.

**Voting Rights**

Each holder of common stock is entitled to one vote for each share for all matters voted on by common stockholders.

***Election of Directors***

Holders of common stock may not cumulate their votes in the election of directors. In an election of directors, each director must be elected by the vote of the majority of the votes cast with respect to that director's election. If a nominee for director is not elected and the nominee is an incumbent director, such incumbent director must promptly tender his or her resignation to the board of directors, subject to acceptance by the board of directors. The Corporate Governance and Policy Committee of the board of directors (the "Corporate Governance and Policy Committee") will make a recommendation to the board of directors as to whether to accept or reject the tendered resignation, or whether other action should be taken. The board of directors will act on the tendered resignation, taking into account the Corporate Governance and Policy Committee's recommendation, and publicly disclose (by a press release, a filing with the Securities and Exchange Commission or other broadly disseminated means of communication) its decision regarding the tendered resignation and the rationale behind the decision within 90 days from the date of certification of election results. The Corporate Governance and Policy Committee in making its recommendation and the board of directors in making its decision may each consider any factors or other information that they consider appropriate and relevant. Any incumbent director who tenders his or her resignation following such failure to be elected will not participate in the recommendation of the Corporate Governance and Policy Committee or the decision of the board of directors with respect to his or her resignation.

If the number of persons properly nominated for election as directors as of the date that is 10 days before the record date for the meeting at which such vote is to be held exceeds the number of directors to be elected, then the directors shall be elected by a plurality of the votes cast.

For purposes of the election of directors, a majority of votes cast shall mean that the number of shares voted "for" the election of a director exceeds the number of votes cast "against" the election of such director.

***Other Matters***

Except with respect to the election of directors as described above, all other matters are determined by a majority of the votes cast, unless otherwise required by law or the certificate of incorporation for the action proposed.

For these purposes, a majority of votes cast shall mean that the number of shares voted "for" a matter exceeds the number of votes cast "against" such matter.

***Quorum***

At least 40% of the shares entitled to vote at the meeting must be present in person or by proxy, in order to constitute a quorum.

**Board of Directors**

Our Bylaws provide that all directors are required to stand for re-election every year. At any meeting of our board of directors, a majority of the total number of the directors constitutes a quorum.

------

**Action without Stockholder Meeting**

Our Restated Certificate of Incorporation also requires that stockholders representing at least two-thirds of the total number of shares outstanding and entitled to vote thereon must sign a written consent for any action without a meeting of the stockholders.

**Advance Notice Bylaws**

Our Bylaws establish advance notice procedures with regard to stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of our stockholders. These procedures provide that notice of such stockholder proposals must be timely given in writing to the Secretary of AT&T prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the anniversary date of the annual meeting for the preceding year. The notice must contain certain information, representations and agreements specified in the Bylaws.

**Proxy Access**

Our Bylaws permit any stockholder or group of up to twenty stockholders who have maintained continuous qualifying ownership of 3% or more of our outstanding common stock for at least the previous three years to include up to a specified number of director nominees in our proxy materials for an annual meeting of stockholders. The maximum number of stockholder nominees permitted under the proxy access provisions of our Bylaws shall be the greater of two or 20% of the total number of directors of AT&T on the last day a notice of nomination may be submitted.

Notice of a nomination pursuant to the proxy access provisions of our Bylaws must be submitted to the Secretary of AT&T at our principal executive office no earlier than 150 days and no later than 120 days before the anniversary of the date that we mailed our proxy statement for the previous year's annual meeting of stockholders. The notice must contain certain information, representations and agreements specified in our Bylaws.

**Section 203 of the General Corporation Law of the State of Delaware**

We are also subject to Section 203 of the General Corporation Law of the State of Delaware. Section 203 prohibits us from engaging in any business combination (as defined in Section 203) with an "interested stockholder" for a period of three years subsequent to the date on which the stockholder became an interested stockholder unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prior to such date, our board of directors approves either the business combination or the transaction in which the stockholder became an interested stockholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owns at least 85% of the outstanding voting stock (with certain exclusions); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the business combination is approved by our board of directors and authorized by a vote (and not by written consent) of at least 66 2/3% of the outstanding voting stock not owned by the interested stockholder.

For purposes of Section 203, an "interested stockholder" is defined as an entity or person beneficially owning 15% or more of our outstanding voting stock, based on voting power, and any entity or person affiliated with or controlling or controlled by such an entity or person.

A "business combination" includes mergers, asset sales and other transactions resulting in financial benefit to a stockholder. Section 203 could prohibit or delay mergers or other takeover or change of control attempts with respect to us and, accordingly, may discourage attempts that might result in a premium over the market price for the shares held by stockholders.

Such provisions may have the effect of deterring hostile takeovers or delaying changes in control of management or us.

**DESCRIPTION OF THE DEPOSITARY SHARES<br>AND 5.000% PERPETUAL PREFERRED STOCK, SERIES A**

*The following summary of AT&T's above referenced securities is based on and qualified by the pertinent sections of our Restated Certificate of Incorporation, including the Certificate of Designations creating the 5.000% Perpetual Preferred Stock, Series A (the "Series A"). For a complete description of the terms and provisions of the depositary shares and the Series A, please refer to our Restated Certificate of Incorporation, which is filed as an exhibit to AT&T's Annual Report on Form 10-K for the year ended December 31, 2025 and to the Certificate of Designations, which is filed an exhibit to a Form 8-A filed with the Securities and Exchange Commission on December 12, 2019.*

*References to the "holders" of the Series A shall mean Computershare Inc. and Computershare Trust Company, N.A., (the "Depositary"). References to "holders" of depositary shares mean those who own depositary shares registered in their own names, on the books that we or the Depositary maintain for this purpose, and not indirect holders who own beneficial interests in depositary shares registered in street name or issued in book-entry form through the Depositary Trust Company ("DTC"). Holders of the depositary shares are entitled through the Depositary to exercise their proportional rights and preferences of the Series A, as described under "Description of the Depositary Shares."*

**DESCRIPTION OF THE 5.000% PERPETUAL PREFERRED STOCK, SERIES A**

**General**

Under our Restated Certificate of Incorporation, we have the authority to issue up to 10,000,000 shares of preferred stock, par value $1.00 per share. Our board of directors (or a duly authorized committee of the board) is authorized without further stockholder action to cause the issuance of shares of preferred stock, including the Series A. The Series A represents a single series of our authorized preferred stock.

We have issued 48,000 shares of the Series A, which remains the amount outstanding, subject to our ability to reopen and issue additional shares and/or increase or decrease the number of designated shares of Series A as described below. The shares of Series A are fully paid and nonassessable and are not convertible into, or exchangeable for, shares of our common stock or any other class or series of our other securities and are not subject to any sinking fund or any other obligation of us for their repurchase or retirement. The shares of Series A have a "stated amount" per share of $25,000 and are held solely by the Depositary as described under "Description of the Depositary Shares" below.

The number of designated shares of Series A may from time to time be increased (but not in excess of the total number of shares of preferred stock authorized under our Restated Certificate of Incorporation, less shares of any other series of preferred stock designated at the time of such increase) or decreased (but not below the number of shares of Series A then outstanding) by resolution of the board (or a duly authorized committee of the board), without the vote or consent of the holders of the Series A. Shares of Series A that are redeemed, purchased or otherwise acquired by us will be cancelled and shall revert to authorized but unissued shares of preferred stock undesignated as to series. We have the authority to issue fractional shares of Series A.

**Ranking**

With respect to the payment of dividends and distributions of assets upon any liquidation, dissolution or winding up, the Series A ranks:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• senior to our common stock and any class or series of our stock that ranks junior to the Series A in the payment of dividends or in the distribution of assets upon our liquidation, dissolution or winding up (including our common stock, "junior stock");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• senior to or on a parity with each other series of our preferred stock we may issue (except for any senior series that may be issued upon the requisite vote or consent of the holders of at least two thirds of the shares of the Series A at the time outstanding and entitled to vote, voting together with any other series of preferred stock that would be adversely affected by such issuance substantially in the same manner and entitled to vote as a single class in proportion to their respective stated amounts) with respect to the payment of dividends and distributions of assets upon any liquidation, dissolution or winding up of the Company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• junior to all existing and future indebtedness and other non-equity claims on us.

------

**Dividends**

Holders of Series A shall be entitled to receive, when, as and if declared by our board (or a duly authorized committee of the board), but only out of funds legally available therefor, cumulative cash dividends at the annual rate of 5.000% of the stated amount per share, and no more, payable quarterly in arrears on the 1st day of each February, May, August and November, respectively, in each year, beginning on February 1, 2020 (each, a "dividend payment date"), with respect to the dividend period (or portion thereof) ending on the day preceding such respective dividend payment date, to holders of record on the 15th calendar day before such dividend payment date or such other record date not more than 60 nor less than 10 days preceding such dividend payment date fixed for that purpose by our board (or a duly authorized committee of the board) in advance of payment of each particular dividend. The amount of the dividend per share of Series A for each dividend period (or portion thereof) is calculated on the basis of a 360-day year consisting of twelve 30-day months. If any dividend payment date is not a business day, the applicable dividend will be paid on the first business day following that day without adjustment. We will not pay interest or any sum of money instead of interest on any dividend payment that may be in arrears on the Series A.

"Dividend period" means each period commencing on (and including) a dividend payment date and continuing to (but not including) the next succeeding dividend payment date, except that the first dividend period for the initial issuance of shares of Series A shall commence on (and include) the original issue date.

A "business day" means each Monday, Tuesday, Wednesday, Thursday or Friday on which banking institutions in The City of New York are not authorized or obligated by law, regulation or executive order to close.

**Restrictions on Dividends, Redemption and Repurchases**

So long as any share of Series A remains outstanding, unless full accrued dividends on all outstanding shares of Series A through and including the most recently completed dividend period have been paid or declared and a sum sufficient for the payment thereof has been set aside for payment:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) no dividend may be declared or paid or set aside for payment on any junior stock, other than a dividend payable solely in stock that ranks junior to the Series A in the payment of dividends and in the distribution of assets on any liquidation, dissolution or winding up of the Company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) no monies may be paid or made available for a sinking fund for the redemption or retirement of junior stock, nor shall any shares of junior stock be purchased, redeemed or otherwise acquired for consideration by us, directly or indirectly, other than:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• as a result of (x) a reclassification of junior stock, or (y) the exchange or conversion of one share of junior stock for or into another share of stock that ranks junior to the Series A in the payment of dividends and in the distribution of assets on any liquidation, dissolution or winding up of the Company; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through the use of the proceeds of a substantially contemporaneous sale of other shares of stock that ranks junior to the Series A in the payment of dividends and in the distribution of assets on any liquidation, dissolution or winding up of the Company; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchases, redemptions or other acquisitions of shares of junior stock in connection with any employment contract, benefit plan, or other similar arrangement with or for the benefit of employees, officers, directors or consultants.

"Accrued dividends" means, with respect to shares of Series A, an amount computed at the annual dividend rate for Series A from, as to each share, the date of issuance of such share to and including the date to which such dividends are to be accrued (whether or not such dividends have been declared), less the aggregate amount of all dividends previously paid on such share.

If our board (or a duly authorized committee of the board) elects to declare only partial instead of full dividends for a dividend payment date and related dividend period on the shares of Series A or any class or series of our stock that ranks on a parity with Series A in the payment of dividends ("dividend parity stock"), then to the extent permitted by the terms of the Series A and each outstanding series of dividend parity stock such partial dividends shall be declared on shares of Series A and dividend parity stock, and dividends so declared shall be paid, as to any such dividend payment date and related dividend period in amounts such that the ratio of the partial dividends declared and paid on each such series to full dividends on each such series is the same. As used in this paragraph, "full dividends" means, as to the Series A and any dividend parity stock that bears dividends on a

------

cumulative basis, the amount of dividends that would need to be declared and paid to bring the Series A and such dividend parity stock current in dividends, including undeclared dividends for past dividend periods (that is, for Series A, full accrued dividends). To the extent a dividend period with respect to the Series A or any series of dividend parity stock (in either case, the "first series") coincides with more than one dividend period with respect to another series as applicable (in either case, a "second series"), for purposes of the immediately preceding sentence our board (or a duly authorized committee of the board) may, to the extent permitted by the terms of each affected series, treat such dividend period for the first series as two or more consecutive dividend periods, none of which coincides with more than one dividend period with respect to the second series, or may treat such dividend period(s) with respect to any dividend parity stock and dividend period(s) with respect to the Series A for purposes of the immediately preceding sentence in any other manner that it deems to be fair and equitable in order to achieve ratable payments of dividends on such dividend parity stock and the Series A.

Subject to the foregoing, and not otherwise, such dividends (payable in cash, stock or otherwise) as may be determined by our board (or a duly authorized committee of the board) may be declared and paid on any junior stock from time to time out of any funds legally available therefor, and the shares of Series A shall not be entitled to participate in any such dividend.

**Optional Redemption**

The Series A is perpetual and has no maturity date. We may, at our option, redeem the shares of Series A:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in whole or in part, at any time on or after December 12, 2024, at a cash redemption price equal to the stated amount (*i.e.*, $25,000 per share of Series A) (equivalent to $25.00 per depositary share), plus (except as otherwise provided herein) an amount equal to all accrued and unpaid dividends thereon (whether or not declared), to, but not including, the date fixed for redemption; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) in whole but not in part at any time within 90 days after the conclusion of any review or appeal process instituted by us following the occurrence of a ratings event at a cash redemption price equal to $25,500 per share of Series A (equivalent to $25.50 per depositary share), plus (except as otherwise provided herein) an amount equal to all accrued and unpaid dividends thereon (whether or not declared) to, but not including, the date fixed for redemption.

"Ratings event" means that any nationally recognized statistical rating organization as defined in Section 3(a)(62) of the Exchange Act or in any successor provision thereto, that then publishes a rating for us (a "rating agency") amends, clarifies or changes the criteria it uses to assign equity credit to securities such as the Series A, which amendment, clarification or change results in:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the shortening of the length of time the Series A is assigned a particular level of equity credit by that rating agency as compared to the length of time they would have been assigned that level of equity credit by that rating agency or its predecessor on the initial issuance of the Series A; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the lowering of the equity credit (including up to a lesser amount) assigned to the Series A by that rating agency as compared to the equity credit assigned by that rating agency or its predecessor on the initial issuance of the Series A.

The redemption price for any shares of Series A shall be payable on the redemption date to the holder of such shares against surrender of the certificate(s) evidencing such shares to us or our agent, if the shares of Series A are issued in certificated form. Any accrued but unpaid dividends payable on a redemption date that occurs subsequent to the applicable record date for a dividend period shall not be paid to the holder entitled to receive the redemption price on the redemption date, but rather shall be paid to the holder of record of the redeemed shares on such record date relating to the applicable dividend payment date.

In case of any redemption of only part of the shares of Series A at the time outstanding, the shares to be redeemed shall be selected either *pro rata* from the holders of record of Series A in proportion to the number of shares of Series A held by such holders or by lot. Subject to the provisions hereof, our board (or a duly authorized committee of the board) shall have full power and authority to prescribe the terms and conditions on which shares of Series A shall be redeemed from time to time. If we shall have issued certificates for the Series A and fewer than all shares represented by any certificates are redeemed, new certificates shall be issued representing the unredeemed shares without charge to the holders thereof.

**Redemption Procedures**

A notice of every redemption of shares of Series A shall be given by first class mail, postage prepaid, addressed to the holders of record of the shares to be redeemed at their respective last addresses appearing on our

------

books. Such mailing shall be at least 30 days and not more than 60 days before the date fixed for redemption. Any notice mailed as provided in this paragraph shall be conclusively presumed to have been duly given, whether or not the holder receives such notice, but failure duly to give such notice by mail, or any defect in such notice or in the mailing thereof, to any holder of shares of Series A designated for redemption shall not affect the validity of the proceedings for the redemption of any other shares of Series A. Notwithstanding the foregoing, if the Series A or any depositary shares representing interests in the Series A are issued in book-entry form through The Depository Trust Company or any other similar facility, the Depositary Trust Company or such other facility will provide notice of redemption by any authorized method to holders of record of the applicable Series A or depositary shares representing interests in the Series A not less than 30, nor more than 60, days prior to the date fixed for redemption of the Series A and related depositary shares.

Each notice of redemption given to a holder shall state:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the redemption date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the number of shares of the Series A to be redeemed and, if less than all shares of the Series A held by such holder are to be redeemed, the number of shares to be redeemed from such holder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the redemption price;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the place or places where certificates for such shares are to be surrendered for payment of the redemption price; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• that dividends will cease to accrue on the redemption date.

If notice of redemption has been duly given, and if on or before the redemption date specified in the notice all funds necessary for the redemption have been set aside by us, separate and apart from our other funds, in trust for the *pro rata* benefit of the holders of the shares called for redemption, so as to be and continue to be available for that purpose, then, notwithstanding that any certificate for any share so called for redemption has not been surrendered for cancellation in the case that the shares of Series A are issued in certificated form, on and after the redemption date dividends shall cease to accrue on all shares so called for redemption, all shares so called for redemption shall no longer be deemed outstanding and all rights with respect to such shares shall forthwith on such redemption date cease and terminate, except only the right of the holders thereof to receive the amount payable on such redemption, without interest. Any funds unclaimed at the end of two years from the redemption date, to the extent permitted by law, shall be released from the trust so established and may be commingled with our other funds, and after that time the holders of the shares so called for redemption shall look only to us for payment of the redemption price of such shares.

The Series A is not subject to any mandatory redemption, sinking fund or other similar provisions. Holders of Series A do not have the right to require redemption of any shares of Series A.

**Liquidation Right**

In the event of any liquidation, dissolution or winding up of the affairs of the Company, whether voluntary or involuntary, before any distribution or payment out of our assets may be made to or set aside for the holders of any junior stock, holders of Series A will be entitled to receive out of our assets legally available for distribution to our stockholders an amount equal to the stated amount per share, together with an amount equal to all accrued dividends to the date of payment whether or not earned or declared (the "liquidation preference").

If our assets are not sufficient to pay the liquidation preference in full to all holders of Series A and all holders of any class or series of our stock that ranks on a parity with Series A in the distribution of assets on liquidation, dissolution or winding up of the Company (the "liquidation preference parity stock"), the amounts paid to the holders of Series A and to the holders of all liquidation preference parity stock shall be *pro rata* in accordance with the respective aggregate liquidation preferences of Series A and all such liquidation preference parity stock. In any such distribution, the "liquidation preference" of any holder of our stock other than the Series A means the amount otherwise payable to such holder in such distribution (assuming no limitation on our assets available for such distribution), including an amount equal to any declared but unpaid dividends in the case of any holder of stock on which dividends accrue on a noncumulative basis and, in the case of any holder of stock on which dividends accrue on a cumulative basis, an amount equal to any unpaid, accrued, cumulative dividends, whether or not earned or declared, as applicable. If the liquidation preference has been paid in full to all holders of Series A and all holders of any liquidation preference parity stock, the holders of junior stock will be entitled to receive all of our remaining assets according to their respective rights and preferences.

------

For purposes of the liquidation rights, the merger, consolidation or other business combination of us with or into any other corporation, including a transaction in which the holders of Series A receive cash, securities or property for their shares, or the sale, conveyance, lease, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of our assets, shall not constitute a liquidation, dissolution or winding up of the Company.

**Voting Rights**

Except as indicated below or otherwise required by law, the holders of the Series A do not have any voting rights.

*Right to Elect Two Directors on Nonpayment Events*. If and whenever dividends payable on Series A have not been declared and paid in an aggregate amount equal to full dividends for at least six quarterly dividend periods or their equivalent (whether or not consecutive) (a "nonpayment event"), the number of directors then constituting our board shall be automatically increased by two and the holders of Series A, together with the holders of any and all other series of outstanding voting preferred stock then entitled to vote for additional directors, voting together as a single class in proportion to their respective stated amounts, shall be entitled to elect the two additional directors (the "preferred stock directors"); *provided* that our board shall at no time include more than two preferred stock directors (including, for purposes of this limitation, all directors that the holders of any series of voting preferred stock are entitled to elect pursuant to like voting rights).

"Voting preferred stock" means any other class or series of preferred stock that ranks equally with the Series A as to the payment of dividends and as to the distribution of assets upon liquidation, dissolution or winding up of the affairs of the Company and upon which like voting rights have been conferred and are exercisable.

In the event that the holders of Series A and such other holders of voting preferred stock shall be entitled to vote for the election of the preferred stock directors following a nonpayment event, such directors shall be initially elected following such nonpayment event only at a special meeting called at the request of the holders of record of at least 20% of (i) the stated amount of the Series A and (ii) each other series of voting preferred stock then outstanding (unless such request for a special meeting is received less than 90 days before the date fixed for the next annual or special meeting of our stockholders, in which event such election shall be held only at such next annual or special meeting of stockholders), and at each subsequent annual meeting of our stockholders. Such request to call a special meeting for the initial election of the preferred stock directors after a nonpayment event shall be made by written notice, signed by the requisite holders of Series A or voting preferred stock, and delivered to our Secretary in such manner as provided for in the certificate of designations creating the Series A, or as may otherwise be required or permitted by applicable law. If our Secretary fails to call a special meeting for the election of the preferred stock directors within 20 days of receiving proper notice, any holder of Series A may call such a meeting at our expense solely for the election of the preferred stock directors, and for this purpose and no other (unless provided otherwise by applicable law) such Series A holder shall have access to our stock ledger.

At each meeting of stockholders at which holders of the Series A and such other holders of voting preferred stock are entitled to vote for the election of the preferred stock directors, the holders of record of 40% of the total number of the Series A and voting preferred stock (determined on a series by series basis) entitled to vote at the meeting, present in person or by proxy, will constitute a quorum for the transaction of business. Each preferred stock director will be elected by a vote of the majority of the votes cast with respect to that preferred stock director's election.

When (i) accrued dividends have been paid in full on the Series A after a nonpayment event, and (ii) the rights of holders of any voting preferred stock to participate in electing the preferred stock directors shall have ceased, the right of holders of the Series A to participate in the election of preferred stock directors shall cease (but subject always to the revesting of such voting rights in the case of any future nonpayment event), the terms of office of all the preferred stock directors shall immediately terminate, and the number of directors constituting our board shall automatically be reduced accordingly.

Any preferred stock director may be removed at any time without cause by the holders of record of a majority of the outstanding shares of Series A and voting preferred stock, when they have the voting rights described above (voting together as a single class in proportion to their respective stated amounts). The preferred stock directors elected at any such special meeting shall hold office until the next annual meeting of the stockholders if such office shall not have previously terminated as above provided. In case any vacancy shall occur among the preferred stock directors, a successor shall be elected by our board to serve until the next annual meeting of the stockholders on the nomination of the then remaining preferred stock director or, if no preferred stock director remains in office, by the vote of the holders of record of a majority of the outstanding shares of Series A and such

------

voting preferred stock for which dividends have not been paid, voting as a single class in proportion to their respective stated amounts. The preferred stock directors shall each be entitled to one vote per director on any matter that shall come before our board for a vote.

***Other Voting Rights***

So long as any shares of the Series A are outstanding, in addition to any other vote or consent of stockholders required by law or by our Restated Certificate of Incorporation, the vote or consent of the holders of at least two-thirds of the shares of Series A at the time outstanding, voting together with any other series of preferred stock that would be adversely affected in substantially the same manner and entitled to vote as a single class in proportion to their respective stated amounts (to the exclusion of all other series of preferred stock), given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, will be necessary for effecting or validating:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Amendment of Restated Certificate of Incorporation or Bylaws**. Any amendment, alteration or repeal of any provision of our Restated Certificate of Incorporation or Bylaws that would alter or change the voting powers, preferences or special rights of the Series A so as to affect them adversely; *provided*, *however*, that the amendment of the Restated Certificate of Incorporation so as to authorize or create, or to increase the authorized amount of, any class or series of stock that does not rank senior to the Series A in either the payment of dividends or in the distribution of assets on any liquidation, dissolution or winding up of the Company shall not be deemed to affect adversely the voting powers, preferences or special rights of the Series A;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Authorization of Senior Stock**. Any amendment or alteration of the certificate of incorporation to authorize or create, or increase the authorized amount of, any shares of any class or series or any securities convertible into shares of any class or series of our capital stock ranking prior to Series A in the payment of dividends or in the distribution of assets on any liquidation, dissolution or winding up of the Company; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Share Exchanges, Reclassifications, Mergers and Consolidations and Other Transactions**. Any consummation of (x) a binding share exchange or reclassification involving the Series A or (y) a merger or consolidation of the Company with another entity (whether or not a corporation), unless in each case (A) the shares of Series A remain outstanding or, in the case of any such merger or consolidation with respect to which we are not the surviving or resulting entity, the shares of Series A are converted into or exchanged for preference securities of the surviving or resulting entity or its ultimate parent and such surviving or resulting entity or ultimate parent, as the case may be, is organized under the laws of the United States or a state thereof, and (B) such shares remaining outstanding or such preference securities, as the case may be, have such rights, preferences, privileges and voting powers, and limitations and restrictions, and limitations and restrictions thereof, taken as a whole, as are not materially less favorable to the holders thereof than the rights, preferences, privileges and voting powers, and restrictions and limitations thereof, of the Series A immediately prior to such consummation, taken as a whole.

To the fullest extent permitted by law, without the consent of the holders of the Series A, so long as such action does not adversely affect the special rights, preferences, privileges and voting powers, and limitations and restrictions thereof, of the Series A, we may amend, alter, supplement or repeal any terms of the Series A contained in our Restated Certificate of Incorporation or the certificate of designations for the following purposes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) to cure any ambiguity, omission, inconsistency or mistake in any such instrument; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) to make any provision with respect to matters or questions relating to the Series A that is not inconsistent with the provisions of the certificate of designations.

The foregoing voting provisions will not apply if, at or prior to the time when the act with respect to which the vote would otherwise be required shall be effected, all outstanding shares of the Series A have been redeemed or called for redemption on proper notice and sufficient funds have been set aside by us for the benefit of the holders of

------

the Series A to effect the redemption, unless in the case of a vote or consent required to authorize senior stock if the shares of Series A are being redeemed with the proceeds from the sale of the stock to be authorized.

Under current provisions of the Delaware General Corporation Law, the holders of issued and outstanding preferred stock are entitled to vote as a class, with the consent of the majority of the class being required to approve an amendment to our Restated Certificate of Incorporation if the amendment would increase or decrease the aggregate number of authorized shares of such class or increase or decrease the par value of the shares of such class.

**No Preemptive and Conversion Rights**

Holders of the Series A do not have any preemptive rights. The Series A is not convertible into or exchangeable for property or shares of any other series or class of our capital stock.

**Additional Classes or Series of Stock**

We have the right to create and issue additional classes or series of stock ranking equally with or junior to the Series A as to dividends and distribution of assets upon our liquidation, dissolution, or winding up without the consent of the holders of the Series A, or the holders of the related depositary shares.

**Transfer Agent and Registrar**

Computershare Trust Company, N.A. is the transfer agent and registrar for the Series A as of the original issue date. We may terminate such appointment and may appoint a successor transfer agent and/or registrar at any time and from time to time, provided that we will use our best efforts to ensure that there is, at all relevant times when the Series A is outstanding, a person or entity appointed and serving as transfer agent and/or registrar. The transfer agent and/or registrar may be a person or entity affiliated with us.

**DESCRIPTION OF THE DEPOSITARY SHARES**

**General**

We have issued fractional interests in shares of the Series A in the form of depositary shares. Each depositary share represents a 1/1,000th ownership interest in a share of the Series A and is evidenced by a depositary receipt.

The Series A represented by depositary shares has been deposited under a deposit agreement among us, Computershare Inc. and Computershare Trust Company, N.A., as the Depositary, and the holders from time to time of the depositary receipts evidencing the depositary shares. Subject to the terms of the deposit agreement, each holder of a depositary share is entitled, through the Depositary, in proportion to the applicable fraction of a share of the Series A represented by such depositary shares, to all the rights and preferences of the Series A represented thereby (including dividend, voting, redemption and liquidation rights).

The depositary shares are listed on the NYSE under the symbol "T PRA".

**Dividends and Other Distributions**

Each dividend on a depositary share will be in an amount equal to 1/1,000th of the dividend declared on the related share of the Series A.

The Depositary distributes any cash dividends or other cash distributions received in respect of the deposited Series A to the record holders of depositary shares relating to the underlying Series A in proportion to the number of depositary shares held by each holder on the relevant record date. The Depositary distributes any property received by it other than cash to the record holders of depositary shares entitled to those distributions in proportion to the number of depositary shares held by each such holder, unless it determines that the distribution cannot be made proportionally among those holders or that it is not feasible to make such distribution. In that event, the Depositary may, with our approval, sell such property received by it and distribute the net proceeds from the sale to the holders of the depositary shares entitled to such distribution in proportion to the number of depositary shares they hold.

Record dates for the payment of dividends and other matters relating to the depositary shares are the same as the corresponding record dates for the Series A.

The amounts distributed to holders of depositary shares are reduced by any amounts required to be withheld by the Depositary or by us on account of taxes or other governmental charges.

**Redemption of Depositary Shares**

If we redeem the Series A represented by the depositary shares, in whole or in part, a corresponding number of depositary shares will be redeemed from the proceeds received by the Depositary resulting from the redemption of the Series A held by the Depositary. The redemption price per depositary share will be equal to

------

1/1,000th of the redemption price per share payable with respect to the Series A, plus an amount equal to any dividends thereon that, pursuant to the provisions of the Certificate of Designations, are payable upon redemption. Whenever we redeem shares of the Series A held by the Depositary, the Depositary will redeem, as of the same redemption date, the number of depositary shares representing shares of the Series A so redeemed.

In case of any redemption of less than all of the outstanding depositary shares, the depositary shares to be redeemed will be selected by the Depositary either *pro rata* or by lot. In any such case, we will redeem depositary shares only in increments of 1,000 depositary shares and any integral multiple thereof.

The Depositary will provide notice of redemption by any authorized method to holders of the depositary shares not less than 30 and not more than 60 days prior to the date fixed for redemption of the Series A and the related depositary shares.

After the date fixed for redemption, the depositary shares called for redemption will no longer be deemed to be outstanding, and all rights of the holders of those shares will cease, except the right to receive the amount payable and any other property to which the holders were entitled upon the redemption. To receive this amount or other property, the holders must surrender the depositary receipts evidencing their depositary shares to the depositary. Any funds that we deposit with the Depositary for any depositary shares that the holders fail to redeem will be returned to us after a period of two years from the date we deposit the funds.

**Voting the Shares**

Because each depositary share represents a 1/1,000th interest in a share of the Series A, holders of depositary shares are entitled to a 1/1,000th of a vote per depositary share under those limited circumstances in which holders of the Series A are entitled to a vote, as described above in "Description of the 5.000% Perpetual Preferred Stock, Series A-Voting Rights."

When the depositary receives notice of any meeting at which the holders of the Series A are entitled to vote, the Depositary will mail (or otherwise transmit by an authorized method) the information contained in the notice to the record holders of the depositary shares relating to the Series.

Each record holder of the depositary shares on the record date, which will be the same date as the record date for the Series A, may instruct the Depositary to vote the amount of the Series A represented by the holder's depositary shares. Although each depositary share is entitled to 1/1,000th of a vote, the Depositary can only vote whole shares of Series A. To the extent possible, the Depositary will vote the amount of the Series A represented by depositary shares in accordance with the instructions it receives. We will agree to take all reasonable actions that the Depositary determines are necessary to enable the Depositary to vote as instructed. If the Depositary does not receive specific instructions from the holders of any depositary shares representing the Series A, it will not vote the amount of the Series A represented by such depositary shares.

**Form of the Depositary Shares**

The depositary shares are issued in book-entry form through DTC. The Series A is issued in registered form to the Depositary.

*References to the "holders" of the Series C shall mean Computershare Inc. and Computershare Trust Company, N.A., (the "Depositary"). References to "holders" of depositary shares mean those who own depositary shares registered in their own names, on the books that we or the Depositary maintain for this purpose, and not indirect holders who own beneficial interests in depositary shares registered in street name or issued in book-entry* 

------

*form through the Depositary Trust Company ("DTC"). Holders of the depositary shares are entitled through the Depositary to exercise their proportional rights and preferences of the Series C, as described under "Description of the Depositary Shares."*

**DESCRIPTION OF THE 4.750% PERPETUAL PREFERRED STOCK, SERIES C**

**General**

Under our Restated Certificate of Incorporation, we have the authority to issue up to 10,000,000 shares of preferred stock, par value $1.00 per share. Our board of directors (or a duly authorized committee of the board) is authorized without further stockholder action to cause the issuance of shares of preferred stock, including the Series C. The Series C represents a single series of our authorized preferred stock.

We have issued 70,000 shares of the Series C, which remains the amount outstanding, subject to our ability to reopen and issue additional shares and/or increase or decrease the number of designated shares of Series C as described below. The shares of Series C are fully paid and nonassessable and are not convertible into, or exchangeable for, shares of our common stock or any other class or series of our other securities and are not subject to any sinking fund or any other obligation of us for their repurchase or retirement. The shares of Series C have a "stated amount" per share of $25,000 and are held solely by the Depositary as described under "Description of the Depositary Shares" below.

The number of designated shares of Series C may from time to time be increased (but not in excess of the total number of shares of preferred stock authorized under our Restated Certificate of Incorporation, less shares of any other series of preferred stock designated at the time of such increase) or decreased (but not below the number of shares of Series C then outstanding) by resolution of the board (or a duly authorized committee of the board), without the vote or consent of the holders of the Series C. Shares of Series C that are redeemed, purchased or otherwise acquired by us will be cancelled and shall revert to authorized but unissued shares of preferred stock undesignated as to series. We have the authority to issue fractional shares of Series C.

**Ranking**

With respect to the payment of dividends and distributions of assets upon any liquidation, dissolution or winding up, the Series C ranks:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• senior to our common stock and any class or series of our stock that ranks junior to the Series C in the payment of dividends or in the distribution of assets upon our liquidation, dissolution or winding up (including our common stock, "junior stock");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• senior to or on a parity with each other series of our preferred stock we have issued or may issue (except for any senior series that may be issued upon the requisite vote or consent of the holders of at least two thirds of the shares of the Series C at the time outstanding and entitled to vote, voting together with any other series of preferred stock that would be adversely affected by such issuance substantially in the same manner and entitled to vote as a single class in proportion to their respective stated amounts) with respect to the payment of dividends and distributions of assets upon any liquidation, dissolution or winding up of the Company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• junior to all existing and future indebtedness and other non-equity claims on us.

**Dividends**

Holders of Series C shall be entitled to receive, when, as and if declared by our board (or a duly authorized committee of the board), but only out of funds legally available therefor, cumulative cash dividends at the annual rate of 4.750% of the stated amount per share, and no more, payable quarterly in arrears on the 1st day of each February, May, August and November, respectively, in each year, beginning on May 1, 2020 (each, a "dividend payment date"), with respect to the dividend period (or portion thereof) ending on the day preceding such respective dividend payment date, to holders of record on the 10th day of the month before such dividend payment date or such other record date not more than 60 nor less than 10 days preceding such dividend payment date fixed for that purpose by our board (or a duly authorized committee of the board) in advance of payment of each particular dividend. The amount of the dividend per share of Series C for each dividend period (or portion thereof) is calculated on the basis of a 360-day year consisting of twelve 30-day months. If any dividend payment date is not a business day, the applicable dividend will be paid on the first business day following that day without adjustment.

------

We will not pay interest or any sum of money instead of interest on any dividend payment that may be in arrears on the Series C.

"Dividend period" means each period commencing on (and including) a dividend payment date and continuing to (but not including) the next succeeding dividend payment date, except that the first dividend period for the initial issuance of shares of Series C shall commence on (and include) the original issue date.

A "business day" means each Monday, Tuesday, Wednesday, Thursday or Friday on which banking institutions in The City of New York are not authorized or obligated by law, regulation or executive order to close.

**Restrictions on Dividends, Redemption and Repurchases**

So long as any share of Series C remains outstanding, unless full accrued dividends on all outstanding shares of Series C through and including the most recently completed dividend period have been paid or declared and a sum sufficient for the payment thereof has been set aside for payment:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) no dividend may be declared or paid or set aside for payment on any junior stock, other than a dividend payable solely in stock that ranks junior to the Series C in the payment of dividends and in the distribution of assets on any liquidation, dissolution or winding up of the Company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) no monies may be paid or made available for a sinking fund for the redemption or retirement of junior stock, nor shall any shares of junior stock be purchased, redeemed or otherwise acquired for consideration by us, directly or indirectly, other than:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• as a result of (x) a reclassification of junior stock, or (y) the exchange or conversion of one share of junior stock for or into another share of stock that ranks junior to the Series C in the payment of dividends and in the distribution of assets on any liquidation, dissolution or winding up of the Company; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through the use of the proceeds of a substantially contemporaneous sale of other shares of stock that ranks junior to the Series C in the payment of dividends and in the distribution of assets on any liquidation, dissolution or winding up of the Company; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchases, redemptions or other acquisitions of shares of junior stock in connection with any employment contract, benefit plan, or other similar arrangement with or for the benefit of employees, officers, directors or consultants.

"Accrued dividends" means, with respect to shares of Series C, an amount computed at the annual dividend rate for Series C from, as to each share, the date of issuance of such share to and including the date to which such dividends are to be accrued (whether or not such dividends have been declared), less the aggregate amount of all dividends previously paid on such share.

If our board (or a duly authorized committee of the board) elects to declare only partial instead of full dividends for a dividend payment date and related dividend period on the shares of Series C or any class or series of our stock that ranks on a parity with Series C in the payment of dividends ("dividend parity stock"), then to the extent permitted by the terms of the Series C and each outstanding series of dividend parity stock such partial dividends shall be declared on shares of Series C and dividend parity stock, and dividends so declared shall be paid, as to any such dividend payment date and related dividend period in amounts such that the ratio of the partial dividends declared and paid on each such series to full dividends on each such series is the same. As used in this paragraph, "full dividends" means, as to the Series C and any dividend parity stock that bears dividends on a cumulative basis, the amount of dividends that would need to be declared and paid to bring the Series C and such dividend parity stock current in dividends, including undeclared dividends for past dividend periods (that is, for Series C, full accrued dividends). To the extent a dividend period with respect to the Series C or any series of dividend parity stock (in either case, the "first series") coincides with more than one dividend period with respect to another series as applicable (in either case, a "second series"), for purposes of the immediately preceding sentence our board (or a duly authorized committee of the board) may, to the extent permitted by the terms of each affected series, treat such dividend period for the first series as two or more consecutive dividend periods, none of which coincides with more than one dividend period with respect to the second series, or may treat such dividend period(s) with respect to any dividend parity stock and dividend period(s) with respect to the Series C for purposes of the immediately preceding sentence in any other manner that it deems to be fair and equitable in order to achieve ratable payments of dividends on such dividend parity stock and the Series C.

------

Subject to the foregoing, and not otherwise, such dividends (payable in cash, stock or otherwise) as may be determined by our board (or a duly authorized committee of the board) may be declared and paid on any junior stock from time to time out of any funds legally available therefor, and the shares of Series C shall not be entitled to participate in any such dividend.

**Optional Redemption**

The Series C is perpetual and has no maturity date. We may, at our option, redeem the shares of Series C:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in whole or in part, at any time on or after February 18, 2025, at a cash redemption price equal to the stated amount (*i.e.*, $25,000 per share of Series C) (equivalent to $25.00 per depositary share), plus (except as otherwise provided herein) an amount equal to all accrued and unpaid dividends thereon (whether or not declared), to, but not including, the date fixed for redemption; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) in whole but not in part at any time within 90 days after the conclusion of any review or appeal process instituted by us following the occurrence of a ratings event at a cash redemption price equal to $25,500 per share of Series C (equivalent to $25.50 per depositary share), plus (except as otherwise provided herein) an amount equal to all accrued and unpaid dividends thereon (whether or not declared) to, but not including, the date fixed for redemption.

"Ratings event" means that any nationally recognized statistical rating organization as defined in Section 3(a)(62) of the Exchange Act or in any successor provision thereto, that then publishes a rating for us (a "rating agency") amends, clarifies or changes the criteria it uses to assign equity credit to securities such as the Series C, which amendment, clarification or change results in:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the shortening of the length of time the Series C is assigned a particular level of equity credit by that rating agency as compared to the length of time they would have been assigned that level of equity credit by that rating agency or its predecessor on the initial issuance of the Series C; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the lowering of the equity credit (including up to a lesser amount) assigned to the Series C by that rating agency as compared to the equity credit assigned by that rating agency or its predecessor on the initial issuance of the Series C.

The redemption price for any shares of Series C shall be payable on the redemption date to the holder of such shares against surrender of the certificate(s) evidencing such shares to us or our agent, if the shares of Series C are issued in certificated form. Any accrued but unpaid dividends payable on a redemption date that occurs subsequent to the applicable record date for a dividend period shall not be paid to the holder entitled to receive the redemption price on the redemption date, but rather shall be paid to the holder of record of the redeemed shares on such record date relating to the applicable dividend payment date.

In case of any redemption of only part of the shares of Series C at the time outstanding, the shares to be redeemed shall be selected either *pro rata* from the holders of record of Series C in proportion to the number of shares of Series C held by such holders or by lot. Subject to the provisions hereof, our board (or a duly authorized committee of the board) shall have full power and authority to prescribe the terms and conditions on which shares of Series C shall be redeemed from time to time. If we shall have issued certificates for the Series C and fewer than all shares represented by any certificates are redeemed, new certificates shall be issued representing the unredeemed shares without charge to the holders thereof.

**Redemption Procedures**

A notice of every redemption of shares of Series C shall be given by first class mail, postage prepaid, addressed to the holders of record of the shares to be redeemed at their respective last addresses appearing on our books. Such mailing shall be at least 30 days and not more than 60 days before the date fixed for redemption. Any notice mailed as provided in this paragraph shall be conclusively presumed to have been duly given, whether or not the holder receives such notice, but failure duly to give such notice by mail, or any defect in such notice or in the mailing thereof, to any holder of shares of Series C designated for redemption shall not affect the validity of the proceedings for the redemption of any other shares of Series C. Notwithstanding the foregoing, if the Series C or any depositary shares representing interests in the Series C are issued in book-entry form through The Depository Trust Company or any other similar facility, the Depositary Trust Company or such other facility will provide notice of redemption by any authorized method to holders of record of the applicable Series C or depositary shares representing interests in the Series C not less than 30, nor more than 60, days prior to the date fixed for redemption of the Series C and related depositary shares.

------

Each notice of redemption given to a holder shall state:<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the redemption date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the number of shares of the Series C to be redeemed and, if less than all shares of the Series C held by such holder are to be redeemed, the number of shares to be redeemed from such holder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the redemption price;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the place or places where certificates for such shares are to be surrendered for payment of the redemption price; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• that dividends will cease to accrue on the redemption date.

If notice of redemption has been duly given, and if on or before the redemption date specified in the notice all funds necessary for the redemption have been set aside by us, separate and apart from our other funds, in trust for the *pro rata* benefit of the holders of the shares called for redemption, so as to be and continue to be available for that purpose, then, notwithstanding that any certificate for any share so called for redemption has not been surrendered for cancellation in the case that the shares of Series C are issued in certificated form, on and after the redemption date dividends shall cease to accrue on all shares so called for redemption, all shares so called for redemption shall no longer be deemed outstanding and all rights with respect to such shares shall forthwith on such redemption date cease and terminate, except only the right of the holders thereof to receive the amount payable on such redemption, without interest. Any funds unclaimed at the end of two years from the redemption date, to the extent permitted by law, shall be released from the trust so established and may be commingled with our other funds, and after that time the holders of the shares so called for redemption shall look only to us for payment of the redemption price of such shares.

The Series C is not subject to any mandatory redemption, sinking fund or other similar provisions. Holders of Series C do not have the right to require redemption of any shares of Series C.

**Liquidation Right**

In the event of any liquidation, dissolution or winding up of the affairs of the Company, whether voluntary or involuntary, before any distribution or payment out of our assets may be made to or set aside for the holders of any junior stock, holders of Series C will be entitled to receive out of our assets legally available for distribution to our stockholders an amount equal to the stated amount per share, together with an amount equal to all accrued dividends to the date of payment whether or not earned or declared (the "liquidation preference").

If our assets are not sufficient to pay the liquidation preference in full to all holders of Series C and all holders of any class or series of our stock that ranks on a parity with Series C in the distribution of assets on liquidation, dissolution or winding up of the Company (the "liquidation preference parity stock"), the amounts paid to the holders of Series C and to the holders of all liquidation preference parity stock shall be *pro rata* in accordance with the respective aggregate liquidation preferences of Series C and all such liquidation preference parity stock. In any such distribution, the "liquidation preference" of any holder of our stock other than the Series C means the amount otherwise payable to such holder in such distribution (assuming no limitation on our assets available for such distribution), including an amount equal to any declared but unpaid dividends in the case of any holder of stock on which dividends accrue on a noncumulative basis and, in the case of any holder of stock on which dividends accrue on a cumulative basis, an amount equal to any unpaid, accrued, cumulative dividends, whether or not earned or declared, as applicable. If the liquidation preference has been paid in full to all holders of Series C and all holders of any liquidation preference parity stock, the holders of junior stock will be entitled to receive all of our remaining assets according to their respective rights and preferences.

For purposes of the liquidation rights, the merger, consolidation or other business combination of us with or into any other corporation, including a transaction in which the holders of Series C receive cash, securities or property for their shares, or the sale, conveyance, lease, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of our assets, shall not constitute a liquidation, dissolution or winding up of the Company.

**Voting Rights**

Except as indicated below or otherwise required by law, the holders of the Series C do not have any voting rights.

------

*Right to Elect Two Directors on Nonpayment Events*. If and whenever dividends payable on Series C have not been declared and paid in an aggregate amount equal to full dividends for at least six quarterly dividend periods or their equivalent (whether or not consecutive) (a "nonpayment event"), the number of directors then constituting our board shall be automatically increased by two and the holders of Series C, together with the holders of any and all other series of outstanding voting preferred stock then entitled to vote for additional directors, voting together as a single class in proportion to their respective stated amounts, shall be entitled to elect the two additional directors (the "preferred stock directors"); *provided* that our board shall at no time include more than two preferred stock directors (including, for purposes of this limitation, all directors that the holders of any series of voting preferred stock are entitled to elect pursuant to like voting rights).

"Voting preferred stock" means any other class or series of preferred stock that ranks equally with the Series C as to the payment of dividends and as to the distribution of assets upon liquidation, dissolution or winding up of the affairs of the Company and upon which like voting rights have been conferred and are exercisable.

In the event that the holders of Series C and such other holders of voting preferred stock shall be entitled to vote for the election of the preferred stock directors following a nonpayment event, such directors shall be initially elected following such nonpayment event only at a special meeting called at the request of the holders of record of at least 20% of (i) the stated amount of the Series C and (ii) each other series of voting preferred stock then outstanding (unless such request for a special meeting is received less than 90 days before the date fixed for the next annual or special meeting of our stockholders, in which event such election shall be held only at such next annual or special meeting of stockholders), and at each subsequent annual meeting of our stockholders. Such request to call a special meeting for the initial election of the preferred stock directors after a nonpayment event shall be made by written notice, signed by the requisite holders of Series C or voting preferred stock, and delivered to our Secretary in such manner as provided for in the certificate of designations creating the Series C, or as may otherwise be required or permitted by applicable law. If our Secretary fails to call a special meeting for the election of the preferred stock directors within 20 days of receiving proper notice, any holder of Series C may call such a meeting at our expense solely for the election of the preferred stock directors, and for this purpose and no other (unless provided otherwise by applicable law) such Series C holder shall have access to our stock ledger.

At each meeting of stockholders at which holders of the Series C and such other holders of voting preferred stock are entitled to vote for the election of the preferred stock directors, the holders of record of 40% of the total number of the Series C and voting preferred stock (determined on a series by series basis) entitled to vote at the meeting, present in person or by proxy, will constitute a quorum for the transaction of business. Each preferred stock director will be elected by a vote of the majority of the votes cast with respect to that preferred stock director's election.

When (i) accrued dividends have been paid in full on the Series C after a nonpayment event, and (ii) the rights of holders of any voting preferred stock to participate in electing the preferred stock directors shall have ceased, the right of holders of the Series C to participate in the election of preferred stock directors shall cease (but subject always to the revesting of such voting rights in the case of any future nonpayment event), the terms of office of all the preferred stock directors shall immediately terminate, and the number of directors constituting our board shall automatically be reduced accordingly.

Any preferred stock director may be removed at any time without cause by the holders of record of a majority of the outstanding shares of Series C and voting preferred stock, when they have the voting rights described above (voting together as a single class in proportion to their respective stated amounts). The preferred stock directors elected at any such special meeting shall hold office until the next annual meeting of the stockholders if such office shall not have previously terminated as above provided. In case any vacancy shall occur among the preferred stock directors, a successor shall be elected by our board to serve until the next annual meeting of the stockholders on the nomination of the then remaining preferred stock director or, if no preferred stock director remains in office, by the vote of the holders of record of a majority of the outstanding shares of Series C and such voting preferred stock for which dividends have not been paid, voting as a single class in proportion to their respective stated amounts. The preferred stock directors shall each be entitled to one vote per director on any matter that shall come before our board for a vote.

***Other Voting Rights***

So long as any shares of the Series C are outstanding, in addition to any other vote or consent of stockholders required by law or by our Restated Certificate of Incorporation, the vote or consent of the holders of at least two-thirds of the shares of Series C at the time outstanding, voting together with any other series of preferred stock that would be adversely affected in substantially the same manner and entitled to vote as a single class in

------

proportion to their respective stated amounts (to the exclusion of all other series of preferred stock), given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, will be necessary for effecting or validating:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Amendment of Restated Certificate of Incorporation or Bylaws**. Any amendment, alteration or repeal of any provision of our Restated Certificate of Incorporation or Bylaws that would alter or change the voting powers, preferences or special rights of the Series C so as to affect them adversely; *provided*, *however*, that the amendment of the Restated Certificate of Incorporation so as to authorize or create, or to increase the authorized amount of, any class or series of stock that does not rank senior to the Series C in either the payment of dividends or in the distribution of assets on any liquidation, dissolution or winding up of the Company shall not be deemed to affect adversely the voting powers, preferences or special rights of the Series C;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Authorization of Senior Stock**. Any amendment or alteration of the certificate of incorporation to authorize or create, or increase the authorized amount of, any shares of any class or series or any securities convertible into shares of any class or series of our capital stock ranking prior to Series C in the payment of dividends or in the distribution of assets on any liquidation, dissolution or winding up of the Company; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Share Exchanges, Reclassifications, Mergers and Consolidations and Other Transactions**. Any consummation of (x) a binding share exchange or reclassification involving the Series C or (y) a merger or consolidation of the Company with another entity (whether or not a corporation), unless in each case (A) the shares of Series C remain outstanding or, in the case of any such merger or consolidation with respect to which we are not the surviving or resulting entity, the shares of Series C are converted into or exchanged for preference securities of the surviving or resulting entity or its ultimate parent and such surviving or resulting entity or ultimate parent, as the case may be, is organized under the laws of the United States or a state thereof, and (B) such shares remaining outstanding or such preference securities, as the case may be, have such rights, preferences, privileges and voting powers, and limitations and restrictions thereof, taken as a whole, as are not materially less favorable to the holders thereof than the rights, preferences, privileges and voting powers, and restrictions and limitations thereof, of the Series C immediately prior to such consummation, taken as a whole.

To the fullest extent permitted by law, without the consent of the holders of the Series C, so long as such action does not adversely affect the special rights, preferences, privileges and voting powers, and limitations and restrictions thereof, of the Series C, we may amend, alter, supplement or repeal any terms of the Series C contained in our Restated Certificate of Incorporation or the certificate of designations for the following purposes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) to cure any ambiguity, omission, inconsistency or mistake in any such instrument; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) to make any provision with respect to matters or questions relating to the Series C that is not inconsistent with the provisions of the certificate of designations.

The foregoing voting provisions will not apply if, at or prior to the time when the act with respect to which the vote would otherwise be required shall be effected, all outstanding shares of the Series C have been redeemed or called for redemption on proper notice and sufficient funds have been set aside by us for the benefit of the holders of the Series C to effect the redemption, unless in the case of a vote or consent required to authorize senior stock if the shares of Series C are being redeemed with the proceeds from the sale of the stock to be authorized.

Under current provisions of the Delaware General Corporation Law, the holders of issued and outstanding preferred stock are entitled to vote as a class, with the consent of the majority of the class being required to approve an amendment to our Restated Certificate of Incorporation if the amendment would increase or decrease the aggregate number of authorized shares of such class or increase or decrease the par value of the shares of such class.

**No Preemptive and Conversion Rights**

------

Holders of the Series C do not have any preemptive rights. The Series C is not convertible into or exchangeable for property or shares of any other series or class of our capital stock.

**Additional Classes or Series of Stock**

We have the right to create and issue additional classes or series of stock ranking equally with or junior to the Series C as to dividends and distribution of assets upon our liquidation, dissolution, or winding up without the consent of the holders of the Series C, or the holders of the related depositary shares.

**Transfer Agent and Registrar**

Computershare Trust Company, N.A. is the transfer agent and registrar for the Series C as of the original issue date. We may terminate such appointment and may appoint a successor transfer agent and/or registrar at any time and from time to time, provided that we will use our best efforts to ensure that there is, at all relevant times when the Series C is outstanding, a person or entity appointed and serving as transfer agent and/or registrar. The transfer agent and/or registrar may be a person or entity affiliated with us.

**DESCRIPTION OF THE DEPOSITARY SHARES**

**General**

We have issued fractional interests in shares of the Series C in the form of depositary shares. Each depositary share represents a 1/1,000th ownership interest in a share of the Series C and is evidenced by a depositary receipt.

The Series C represented by depositary shares has been deposited under a deposit agreement among us, Computershare Inc. and Computershare Trust Company, N.A., as the Depositary, and the holders from time to time of the depositary receipts evidencing the depositary shares. Subject to the terms of the deposit agreement, each holder of a depositary share is entitled, through the Depositary, in proportion to the applicable fraction of a share of the Series C represented by such depositary shares, to all the rights and preferences of the Series C represented thereby (including dividend, voting, redemption and liquidation rights).

The depositary shares are listed on the NYSE under the symbol "T PRAC".

**Dividends and Other Distributions**

Each dividend on a depositary share will be in an amount equal to 1/1,000th of the dividend declared on the related share of the Series C.

The Depositary distributes any cash dividends or other cash distributions received in respect of the deposited Series C to the record holders of depositary shares relating to the underlying Series C in proportion to the number of depositary shares held by each holder on the relevant record date. The Depositary distributes any property received by it other than cash to the record holders of depositary shares entitled to those distributions in proportion to the number of depositary shares held by each such holder, unless it determines that the distribution cannot be made proportionally among those holders or that it is not feasible to make such distribution. In that event, the Depositary may, with our approval, sell such property received by it and distribute the net proceeds from the sale to the holders of the depositary shares entitled to such distribution in proportion to the number of depositary shares they hold.

Record dates for the payment of dividends and other matters relating to the depositary shares are the same as the corresponding record dates for the Series C.

The amounts distributed to holders of depositary shares are reduced by any amounts required to be withheld by the Depositary or by us on account of taxes or other governmental charges.

**Redemption of Depositary Shares**

If we redeem the Series C represented by the depositary shares, in whole or in part, a corresponding number of depositary shares will be redeemed from the proceeds received by the Depositary resulting from the redemption of the Series C held by the Depositary. The redemption price per depositary share will be equal to 1/1,000th of the redemption price per share payable with respect to the Series C, plus an amount equal to any dividends thereon that, pursuant to the provisions of the Certificate of Designations, are payable upon redemption. Whenever we redeem shares of the Series C held by the Depositary, the Depositary will redeem, as of the same redemption date, the number of depositary shares representing shares of the Series C so redeemed.

In case of any redemption of less than all of the outstanding depositary shares, the depositary shares to be redeemed will be selected by the Depositary either *pro rata* or by lot. In any such case, we will redeem depositary shares only in increments of 1,000 depositary shares and any integral multiple thereof.

------

The Depositary will provide notice of redemption by any authorized method to holders of the depositary shares not less than 30 and not more than 60 days prior to the date fixed for redemption of the Series C and the related depositary shares.

After the date fixed for redemption, the depositary shares called for redemption will no longer be deemed to be outstanding, and all rights of the holders of those shares will cease, except the right to receive the amount payable and any other property to which the holders were entitled upon the redemption. To receive this amount or other property, the holders must surrender the depositary receipts evidencing their depositary shares to the depositary. Any funds that we deposit with the Depositary for any depositary shares that the holders fail to redeem will be returned to us after a period of two years from the date we deposit the funds.

**Voting the Shares**

Because each depositary share represents a 1/1,000th interest in a share of the Series C, holders of depositary shares are entitled to a 1/1,000th of a vote per depositary share under those limited circumstances in which holders of the Series C are entitled to a vote, as described above in "Description of the 4.750% Perpetual Preferred Stock, Series C-Voting Rights."

When the depositary receives notice of any meeting at which the holders of the Series C are entitled to vote, the Depositary will mail (or otherwise transmit by an authorized method) the information contained in the notice to the record holders of the depositary shares relating to the Series.

Each record holder of the depositary shares on the record date, which will be the same date as the record date for the Series C, may instruct the Depositary to vote the amount of the Series C represented by the holder's depositary shares. Although each depositary share is entitled to 1/1,000th of a vote, the Depositary can only vote whole shares of Series C. To the extent possible, the Depositary will vote the amount of the Series C represented by depositary shares in accordance with the instructions it receives. We will agree to take all reasonable actions that the Depositary determines are necessary to enable the Depositary to vote as instructed. If the Depositary does not receive specific instructions from the holders of any depositary shares representing the Series C, it will not vote the amount of the Series C represented by such depositary shares.

**Form of the Depositary Shares**

The depositary shares are issued in book-entry form through DTC. The Series C is issued in registered form to the Depositary.

**DESCRIPTION OF THE 3.550% GLOBAL NOTES DUE 2032**

*The following summary of AT&T's above referenced debt securities is based on and qualified by the indenture, dated as of November 1, 1994, with The Bank of New York Mellon acting as trustee (the "Indenture") and the 3.550% Global Notes due 2032 (the "Notes"). For a complete description of the terms and provisions of the Notes, please refer to the Indenture, which is filed as an exhibit to AT&T's Annual Report on Form 10-K for the year ended December 31, 2025 and to the form of Notes, which is filed as an exhibit to the Form 8-A filed with the Securities and Exchange Commission on December 17, 2012.*

**General**

The Notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• were issued in an aggregate initial principal amount of €1,000,000,000 and an additional aggregate principal amount of €400,000,000 was subsequently issued such that €1,400,000,000 remains the amount outstanding, subject to our ability to issue additional Notes which may be of the same series as the Notes as described under "- Further Issues";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mature on December 17, 2032;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• bear interest at the rate of 3.550% per annum, payable annually in arrears;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are repayable at par at maturity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are redeemable by us at the time described below under "- Optional Redemption" and in connection with certain tax events as described below under "- Redemption Upon a Tax Event"; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are not subject to any sinking fund.

------

The Notes are unsecured and unsubordinated obligations and rank *pari passu* with all other indebtedness issued under our Indenture. The Notes constitutes a separate series under the Indenture. The Notes are issued in fully registered form only and in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. Principal and interest payments on the Notes are payable by us in euro. Payments of principal, interest and additional amounts, if any, in respect of the Notes will be made to Euroclear System, Clearstream Banking S.A. or such nominee or common depositary, as the case may be, as registered holder thereof.

For purposes of the Notes, a business day means a business day in the City of New York and London.

**Interest**

The Notes bear interest at the rate of 3.550% per annum.

We pay interest on the Notes annually in arrears on December 17, commencing on December 17, 2013, to the persons in whose names the Notes are registered at the close of business on the December 1 preceding the interest payment date.

The Notes will mature on December 17, 2032.

Interest on the Notes is computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes, to but excluding the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

**Optional Redemption**

At any time prior to the applicable Par Call Date (as set forth in the table below), the Notes will be redeemable, as a whole or in part, at our option, at any time and from time to time on at least 30 days', but not more than 60 days', prior notice mailed to the registered address of each holder of the Notes of such series to be redeemed. The redemption price will be equal to the greater of (1) 100% of the principal amount of the Notes of such series to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) discounted to the redemption date, on an annual basis (ACTUAL/ACTUAL (ICMA)), at a rate equal to the Treasury Rate (as defined below) plus a number of basis points equal to the applicable Make-Whole Spread (as set forth in the table below). In either case, accrued interest will be payable to the redemption date. At any time on or after the applicable Par Call Date (as set forth in the table below), we have the option to redeem the Notes, as a whole or in part, on at least 30 days', but not more than 60 days', prior notice mailed to the registered address of each holder of the Notes of such series to be redeemed, at a redemption price equal to 100% of the principal amount of such series of Notes to be redeemed. Accrued interest will be payable to the redemption date.

| **Series** | **Par Call Date** | **Make-Whole Spread** |
| 3.550% 2032 Notes | September 17, 2032 | 25 bps |

---

"*Treasury Rate*" means the price, expressed as a percentage (rounded to three decimal places, 0.0005 being rounded upwards), at which the gross redemption yield on the Notes of the applicable series, if they were to be purchased at such price on the third dealing day prior to the date fixed for redemption, would be equal to the gross redemption yield on such dealing day of the Reference Bond (as defined below) on the basis of the middle market price of the Reference Bond prevailing at 11:00 a.m. (London time) on such dealing day as determined by either the Company or an investment bank appointed by the Company.

"*Reference Bond*" means, in relation to any Treasury Rate calculation, a German government bond whose maturity is closest to the maturity of the Notes of the applicable series, or if the Company or an investment bank appointed by the Company considers that such similar bond is not in issue, such other German government bond as the Company or an investment bank appointed by the Company may, with the advice of three brokers of, and/or market makers in, German government bonds selected by the Company or an investment bank appointed by the Company, determine to be appropriate for determining such Treasury Rate.

"*Remaining Scheduled Payments*" means, with respect to each Note of a series to be redeemed, the remaining scheduled payments of principal of and interest on such Note that would be due after the related redemption date but for the redemption. If that redemption date is not an interest payment date with respect to the

applicable series of Notes, the amount of the next succeeding scheduled interest payment on the Notes will be reduced by the amount of interest accrued on the Notes to the redemption date.

------

On and after the redemption date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with a paying agent or the trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date.

In the case of any partial redemption, selection of the Notes to be redeemed will be made by the trustee by lot or by such other method as the trustee in its sole discretion deems to be fair and appropriate.

**Redemption for Taxation Reasons** 

If (a) as a result of any change in, or amendment to, the laws or regulations of a Relevant Jurisdiction (as defined below under "Interpretation"), or any change in the official interpretation of the laws or regulations of a Relevant Jurisdiction, which change or amendment becomes effective after December 11, 2012, on the next Interest Payment Date we would be required to pay additional amounts as provided or referred to below under "- Payment Without Withholding" and (b) the requirement cannot be avoided by our taking reasonable measures available to us, we may at our option, having given not less than 30 nor more than 60 days' notice to the holders of the Notes (which notice shall be irrevocable), redeem all, but not a portion of, the Notes at any time at their principal amount together with interest accrued to, but excluding, the date of redemption provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which we would be obliged to pay such additional amounts were a payment in respect of the Notes then due. Prior to the publication of any notice of redemption pursuant to this paragraph, we shall deliver to the trustee a certificate signed by two of our executive officers stating that the requirement referred to in (a) above will apply on the next Interest Payment Date and setting forth a statement of facts showing that the conditions precedent to the right of AT&T so to redeem have occurred, cannot be avoided by us taking reasonable measures available to us and an opinion of independent legal advisers of recognized international standing to the effect that AT&T has or will become obliged to pay such additional amounts as a result

of the change or amendment, in each case to be held by the trustee and made available for viewing at the offices of the trustee on request by any holder of the Notes.

**Payment Without Withholding** 

All payments in respect of the Notes by or on behalf of AT&T shall be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature ("Taxes") imposed, collected, withheld, assessed or levied by or on behalf of the Relevant Jurisdiction, unless the withholding or deduction of the Taxes is required by law. In that event, we will pay such additional amounts to a holder who is a United States Alien (as defined below) as may be necessary in order that the net amounts received by the holder after the withholding or deduction shall equal the respective amounts which would have been receivable in respect of the Notes in the absence of the withholding or deduction; except that no such additional amounts shall be payable in relation to any payment in respect of any Note:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) where such withholding or deduction would not have been so imposed but for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in the case of payment by AT&T, the existence of any present or former connection between the holder of the Note (or between a fiduciary, settlor, shareholder, beneficiary or member of the holder of the Note, if such holder is an estate, a trust, a corporation or a partnership) and the United States, including, without limitation, such holder (or such fiduciary, settlor, shareholder, beneficiary or member) being or having been a citizen or resident or treated as a resident thereof, or being or having been engaged in trade or business or presence therein, or having or having had a permanent establishment therein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) in the case of payment by AT&T, the present or former status of the holder of the Note as a personal holding company, a foreign personal holding company, a passive foreign investment company, or a controlled foreign corporation for United States federal income tax purposes or a corporation which accumulates earnings to avoid United States federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) in the case of payment by AT&T, the past or present or future status of the holder of the Note as the actual or constructive owner of 10% or more of either the total combined voting power of all classes of stock of AT&T entitled to vote if AT&T was treated as a corporation, or the capital or profits interest in AT&T, if AT&T is treated as a partnership for United States federal income tax purposes or as a bank receiving interest described in Section 881(c) (3) (A) of the Internal Revenue Code of 1986, as amended; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the failure by the holder of the Note to comply with any certification, identification or other reporting requirements concerning the nationality, residence, identity or connection with the United States (in the case of payment by AT&T) of such holder, if compliance is required by statute or by regulation as a precondition to exemption from such withholding or deduction;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) in the case of payment by AT&T to any United States Alien, if such person is a fiduciary or partnership or other than the sole beneficial owner of any such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such partnership or the beneficial owner would not have been entitled to the additional amounts had such beneficiary, settlor, member or beneficial owner been the bearer of such Note. As used herein, "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) to the extent that the withholding or deduction is as a result of the imposition of any gift, inheritance, estate, sales, transfer, personal property or any similar tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) to, or to a third party on behalf of, a holder who is liable for the Taxes in respect of the Notes by reason of his having any or some present or former connection, including but not limited to fiscal residency, fiscal deemed residency and substantial interest shareholdings, with the Relevant Jurisdiction, other than the mere holding of the Notes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) presented for payment more than 30 days after the Relevant Date except to the extent that a holder would have been entitled to additional amounts on presenting the relevant Notes for payment on the last day of the period of 30 days assuming that day to have been an Interest Payment Date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) any tax, assessment or other governmental charge required to be withheld by any paying agent from any payment of principal or of interest on any Notes, if such payment can be made without withholding by any other paying agent;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of our Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) any combination of (a), (b), (c), (d), (e), (f), (g) or (h).

**Interpretation** 

As used in this description:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) "Relevant Date" means the date on which the payment first becomes due but, if the full amount of the money payable has not been received by the trustee on or before the due date, it means the date which is seven days after the date on which, the full amount of the money having been so received, notice to that effect shall have been duly given to the holders of Notes by us; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) "Relevant Jurisdiction" means the State of Delaware and the United States or any political subdivision or any authority thereof or therein having power to tax or any other jurisdiction or any political subdivision or any authority thereof or therein having power to tax to which we become subject in respect of payments made by it of principal and interest on the Notes.

**Additional Amounts** 

Any reference in the terms of the Notes of each series to any amounts in respect of the Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

**Further Issues** 

We may from time to time, without notice to or the consent of the holders of the Notes, create and issue further notes ranking equally and ratably with the Notes in all respects, or in all respects except for the payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date of those further notes. Any further notes will have the same terms as to status, redemption or otherwise as the Notes. Any further notes shall be issued pursuant to a resolution of our board of directors, a supplement to the Indenture, or under an officers' certificate pursuant to the Indenture.

**Governing Law**

The Notes will be governed by and interpreted in accordance with the laws of the State of New York.

**Special Situations Covered by Our Indenture**

------

***Mergers and Similar Transactions***

We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company, or to buy substantially all of the assets of another company. However, we may not take any of these actions unless all the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Where we merge out of existence or sell our assets, the company we merge into or sell to may not be organized under the laws of a foreign country. It must be a corporation organized under the laws of the United States, any State thereof, or the District of Columbia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company we merge into or sell to must agree to be legally responsible for our debt securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merger, sale of assets or other transaction must not cause a default on the securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described below under "- Default and Related Matters - Events of Default - What Is an Event of Default?" A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded.

***Modification and Waiver of Holders' Contractual Rights***

Under certain circumstances, we can make changes to the Indenture and the securities (including the Notes). Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

*Changes Requiring Approval of Holders.* First, there are changes that cannot be made to the securities without specific approval of holders. The following is a list of those types of changes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the percentage of holders of securities who must consent to a waiver or amendment of the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the rate of interest on any security or change the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the principal due on any security or change the fixed maturity of any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to waive a default in the payment of principal or interest on any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the currency of payment on a security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of convertible or exchangeable securities, to make changes to conversion or exchange rights that would be adverse to the interests of holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the right of holders to waive an existing default by majority vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the amount of principal or interest payable to holders following a default or change any conversion or exchange rights, or impair the right of holders to sue for payment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change to this list of changes that requires specific approval of holders.

*Changes Requiring a Majority Vote.* The second type of change to the Indenture and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except for clarifying changes and certain other changes that would not adversely affect holders of the securities. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain each holder's individual consent to the waiver.

*Changes Not Requiring Approval of Holders.* The third type of change does not require any vote by holders of securities. This type includes, among others, clarifications of ambiguous contract terms and other changes that would not materially adversely affect holders of the securities.

*Further Details Concerning Voting.* When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent determined on the date of original issuance of these securities.

------

Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for the applicable holders money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the Indenture. However, the Indenture does not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

***Holders who hold in "street name" and other indirect holders, including holders of any securities issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the Indenture or the securities or request a waiver.***

**Discharge of Our Obligations**

We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for the applicable holders with the trustee and certain other conditions are met. The deposit must be held in trust for the benefit of all direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities.

If we accomplish full discharge, as described above, holders will have to rely solely on the trust deposit for repayment of the securities. Holders could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the trustee and holders against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations.

**Liens on Assets**

The Indenture does not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

**Default and Related Matters**

***Ranking Compared to Other Creditors***

The securities are not secured by any of our property or assets. Accordingly, ownership of securities means each holder is one of our unsecured creditors. The securities are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee has a right to receive payment for its administrative services prior to any payment to security holders after a default.

***Events of Default***

Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

*What Is an Event of Default?* The term "event of default" with respect to any series of securities means any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any interest payment on the securities of such series when it is due, and we do not cure this default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any payment of principal when it is due at the maturity of such series of securities or upon redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to comply with any of our other agreements regarding a particular series of securities or with a supplemental indenture, and after we have been notified of the default by the trustee or holders of 25% in principal amount of the series, we do not cure the default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We file for bankruptcy, or other events in bankruptcy, insolvency or reorganization occur.

***Remedies if an Event of Default Occurs***

Holders and the trustee will have the following remedies if an event of default occurs:

------

*Acceleration.* If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived.

*Special Duties of Trustee.* If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the Indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

*Other Remedies of Trustee.* If an event of default occurs, the trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the Indenture, including bringing a lawsuit.

*Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests*. The trustee is not required to take any action under the Indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an "indemnity". If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the Indenture.

*Individual Actions Holders May Take if the Trustee Fails to Act.* Before a holder bypasses the trustee and brings such holder's own lawsuit or other formal legal action or take other steps to enforce such holder's rights or protect such holder's interests relating to the securities, the following must occur:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such holder must give the trustee written notice that an event of default has occurred and remains uncured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The holders of 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer indemnity reasonably satisfactory to the trustee against the cost and other liabilities of taking that action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the 60-day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with the request.

However, a holder is entitled at any time to bring an individual lawsuit for the payment of the money due on such holder's security on or after its due date.

***Waiver of Default***

The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on a holder's debt security, however, without such holder's individual approval.

***We Will Give the Trustee Information About Defaults Annually***

Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the Indenture and all the securities under it, or else specifying any default.

The trustee may withhold from holders notice of any uncured default, except for payment defaults, if it determines that withholding notice is in holders' interest.

**Holders who hold in "street name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to make or cancel a declaration of acceleration.**

**Regarding the Trustee**

The Bank of New York Mellon is the trustee under the Indenture. In addition, affiliates of The Bank of New York Mellon may perform various commercial banking and investment banking services for us and our subsidiaries from time to time in the ordinary course of business.

**DESCRIPTION OF THE 3.500% GLOBAL NOTES DUE 2025 AND THE 3.375% GLOBAL NOTES DUE 2034**

*The following summary of AT&T's above referenced debt securities is based on and qualified by the indenture, dated as of May 15, 2013, with The Bank of New York Mellon Trust Company, N.A., acting as trustee (the "Indenture") and the 3.500% Global Notes due 2025 (the "2025 Notes") and the 3.375% Global Notes due 2034 (the "2034 Notes" and, together with the 2025 Notes, the "Notes"). For a complete description of the terms and provisions of the Notes, please refer to the Indenture, which is filed as an exhibit to AT&T's Annual Report on Form 10-K for the year ended December 31, 2025 and to the forms of Notes, which are filed as exhibits to the Form 8-As filed with the Securities and Exchange Commission on November 13, 2013 and June 11, 2014.* 

**General** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The 2025 Notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• were issued in an aggregate initial principal amount of €1,000,000,000, which remains the amount outstanding, subject to our ability to issue additional 2025 Notes which may be of the same series as the 2025 Notes as described under "- Further Issues";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• matured on December 17, 2025;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• bear interest at the rate of 3.500% per annum, payable annually in arrears;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are repayable at par at maturity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are redeemable by us at the time described below under "- Optional Redemption" and in connection with certain tax events as described below under "- Redemption Upon a Tax Event"; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are not subject to any sinking fund.

The 2034 Notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• were issued in an aggregate initial principal amount of €500,000,000, which remains the amount outstanding, subject to our ability to issue additional 2034 Notes which may be of the same series as the 2034 Notes as described under "- Further Issues";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mature on March 15, 2034;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• bear interest at the rate of 3.375% per annum, payable annually in arrears;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are repayable at par at maturity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are redeemable by us at the time described below under "- Optional Redemption" and in connection with certain tax events as described below under "- Redemption Upon a Tax Event"; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are not subject to any sinking fund.

The Notes are unsecured and unsubordinated obligations and rank *pari passu* with all other indebtedness issued under our Indenture. Each series of Notes constitutes a separate series under the Indenture. The Notes are issued in fully registered form only and in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. Principal and interest payments on the Notes are payable by us in euro. Payments of principal, interest and additional amounts, if any, in respect of the Notes will be made to Euroclear System, Clearstream Banking S.A. or such nominee or common depositary, as the case may be, as registered holder thereof. Under the terms of the Indenture, if the euro ceases to exist when payments on the Notes are due under any circumstances, AT&T may supplement the Indenture to allow for payment in U.S. dollars. The principal and interest payable in U.S. dollars on a Note at maturity, or upon redemption, will be paid by wire transfer of immediately available funds against presentation of a Note at the office of the paying agent.

For purposes of the Notes, a business day means a business day in the City of New York and London.

**Interest**

------

The 2025 Notes bear interest at the rate of 3.500% per annum and the 2034 Notes bear interest at the rate of 3.375% per annum.

We pay interest on the 2025 Notes annually in arrears on December 17, commencing on December 17, 2014, to the persons in whose names the 2025 Notes are registered at the close of business on the December 1 preceding the interest payment date. We pay interest on the 2034 Notes annually in arrears on March 15, commencing on March 15, 2015, to the persons in whose names the 2034 Notes are registered at the close of business on the business day preceding the interest payment date.

The 2025 Notes matured on December 17, 2025 and the 2034 Notes will mature on March 15, 2034.

Interest on the Notes is computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes, to but excluding the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

**Optional Redemption**

At any time prior to the applicable Par Call Date (as set forth in the table below), the Notes will be redeemable, as a whole or in part, at our option, at any time and from time to time on at least 30 days', but not more than 60 days', prior notice mailed to the registered address of each holder of the Notes of such series to be redeemed. The redemption price will be equal to the greater of (1) 100% of the principal amount of the Notes of such series to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) discounted to the redemption date, on an annual basis (ACTUAL/ACTUAL (ICMA)), at a rate equal to the Treasury Rate (as defined below) plus a number of basis points equal to the applicable Make-Whole Spread (as set forth in the table below). In either case, accrued interest will be payable to the redemption date. At any time on or after the applicable Par Call Date (as set forth in the table below), we have the option to redeem the Notes, as a whole or in part, at our option, at any time and from time to time, on at least 30 days', but not more than 60 days', prior notice mailed to the registered address of each holder of the Notes of such series to be redeemed, at a redemption price equal to 100% of the principal amount of such series of Notes to be redeemed. Accrued interest will be payable to the redemption date.

| | | |
|:---|:---|:---|
| **Series** | **Par Call Date** | **Make-Whole Spread** |
| 2025 Notes | September 17, 2025 | 30 bps |
| 2034 Notes | December 15, 2033 | 20 bps |

---

"*Treasury Rate*" means the price, expressed as a percentage (rounded to three decimal places, 0.0005 being rounded upwards), at which the gross redemption yield on the Notes of the applicable series, if they were to be purchased at such price on the third dealing day prior to the date fixed for redemption, would be equal to the gross redemption yield on such dealing day of the Reference Bond (as defined below) on the basis of the middle market price of the Reference Bond prevailing at 11:00 a.m. (London time) on such dealing day as determined by the Company or an investment bank appointed by the Company.

"*Reference Bond*" means, in relation to any Treasury Rate calculation, a German government bond whose maturity is closest to the maturity of the Notes of the applicable series, or if the Company or an investment bank appointed by the Company considers that such similar bond is not in issue, such other German government bond as the Company or an investment bank appointed by the Company, with the advice of three brokers of, and/or market makers in, German government bonds selected by the Company or an investment bank appointed by the Company, determine to be appropriate for determining such Treasury Rate.

"*Remaining Scheduled Payments*" means, with respect to each Note of a series to be redeemed, the remaining scheduled payments of principal of and interest on such Note that would be due after the related redemption date but for the redemption. If that redemption date is not an interest payment date with respect to the applicable series of Notes, the amount of the next succeeding scheduled interest payment on the Notes will be reduced by the amount of interest accrued on the Notes to the redemption date.

------

On and after the redemption date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with a paying agent or the trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date.

In the case of any partial redemption, selection of the Notes of a series to be redeemed will be made by the trustee by lot or by such other method as the trustee in its sole discretion deems to be fair and appropriate.

**Redemption for Taxation Reasons**

If (a) as a result of any change in, or amendment to, the laws or regulations of a Relevant Jurisdiction (as defined below under "Interpretation"), or any change in the official interpretation of the laws or regulations of a Relevant Jurisdiction, which change or amendment becomes effective after November 5, 2013 with respect to the 2025 Notes and after June 4, 2014 with respect to the 2034 Notes, on the next Interest Payment Date we would be required to pay additional amounts as provided or referred to below under "- Payment Without Withholding" and (b) the requirement cannot be avoided by our taking reasonable measures available to us, we may at our option, having given not less than 30 nor more than 60 days' notice to the holders of the Notes (which notice shall be irrevocable), redeem all, but not a portion of, the Notes at any time at their principal amount together with interest accrued to, but excluding, the date of redemption provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which we would be obliged to pay such additional amounts were a payment in respect of the Notes then due. Prior to the publication of any notice of redemption pursuant to this paragraph, we shall deliver to the trustee a certificate signed by two of our executive officers stating that the requirement referred to in (a) above will apply on the next Interest Payment Date and setting forth a statement of facts showing that the conditions precedent to the right of AT&T so to redeem have occurred, cannot be avoided by us taking reasonable measures available to us and an opinion of independent legal advisers of recognized international standing to the effect that AT&T has or will become obliged to pay such additional amounts as a result of the change or amendment, in each case to be held by the trustee and made available for viewing at the offices of the trustee on request by any holder of the Notes.

**Payment Without Withholding** 

All payments in respect of the Notes by or on behalf of AT&T shall be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature ("Taxes") imposed, collected, withheld, assessed or levied by or on behalf of the Relevant Jurisdiction, unless the withholding or deduction of the Taxes is required by law. In that event, we will pay such additional amounts to a holder who is a United States Alien (as defined below) as may be necessary in order that the net amounts received by the holder after the withholding or deduction shall equal the respective amounts which would have been receivable in respect of the Notes in the absence of the withholding or deduction; except that no such additional amounts shall be payable in relation to any payment in respect of any Note:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) where such withholding or deduction would not have been so imposed but for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in the case of payment by AT&T, the existence of any present or former connection between the holder of the Note (or between a fiduciary, settlor, shareholder, beneficiary or member of the holder of the Note, if such holder is an estate, a trust, a corporation or a partnership) and the United States, including, without limitation, such holder (or such fiduciary, settlor, shareholder, beneficiary or member) being or having been a citizen or resident or treated as a resident thereof, or being or having been engaged in trade or business or presence therein, or having or having had a permanent establishment therein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) in the case of payment by AT&T, the present or former status of the holder of the Note as a personal holding company, a foreign personal holding company, a passive foreign investment company, or a controlled foreign corporation for United States federal income tax purposes or a corporation which accumulates earnings to avoid United States federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) in the case of payment by AT&T, the past or present or future status of the holder of the Note as the actual or constructive owner of 10% or more of either the total combined voting power of all classes of stock of AT&T entitled to vote if AT&T was treated as a corporation, or the capital or profits interest in AT&T, if AT&T is treated as a partnership for United States federal income tax purposes or as a bank receiving interest described in Section 881(c) (3) (A) of the Internal Revenue Code of 1986, as amended; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the failure by the holder of the Note to comply with any certification, identification or other reporting requirements concerning the nationality, residence, identity or connection with the United States (in the case of

------

payment by AT&T) of such holder, if compliance is required by statute or by regulation as a precondition to exemption from such withholding or deduction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) in the case of payment by AT&T to any United States Alien, if such person is a fiduciary or partnership or other than the sole beneficial owner of any such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such partnership or the beneficial owner would not have been entitled to the additional amounts had such beneficiary, settlor, member or beneficial owner been the bearer of such Note. As used herein, "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) to the extent that the withholding or deduction is as a result of the imposition of any gift, inheritance, estate, sales, transfer, personal property or any similar tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) to, or to a third party on behalf of, a holder who is liable for the Taxes in respect of the Notes by reason of his having any or some present or former connection, including but not limited to fiscal residency, fiscal deemed residency and substantial interest shareholdings, with the Relevant Jurisdiction, other than the mere holding of the Notes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) presented for payment more than 30 days after the Relevant Date except to the extent that a holder would have been entitled to additional amounts on presenting the relevant Notes for payment on the last day of the period of 30 days assuming that day to have been an Interest Payment Date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) any tax, assessment or other governmental charge required to be withheld by any paying agent from any payment of principal or of interest on any Notes, if such payment can be made without withholding by any other paying agent;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of our Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) any combination of (a), (b), (c), (d), (e), (f), (g) or (h).

**Interpretation** 

As used in this description:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) "Relevant Date" means the date on which the payment first becomes due but, if the full amount of the money payable has not been received by the trustee on or before the due date, it means the date which is seven days after the date on which, the full amount of the money having been so received, notice to that effect shall have been duly given to the holders of Notes by us; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) "Relevant Jurisdiction" means the State of Delaware and the United States or any political subdivision or any authority thereof or therein having power to tax or any other jurisdiction or any political subdivision or any authority thereof or therein having power to tax to which we become subject in respect of payments made by it of principal and interest on the Notes.

**Additional Amounts** 

Any reference in the terms of the Notes to any amounts in respect of the Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

**Further Issues** 

We may from time to time, without notice to or the consent of the holders of the Notes, create and issue further notes ranking equally and ratably with such series of Notes in all respects, or in all respects except for the payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date of those further notes. Any further notes will have the same terms as to status, redemption or otherwise as the Notes. Any further notes shall be issued pursuant to a resolution of our board of directors, a supplement to the Indenture, or under an officers' certificate pursuant to the Indenture.

**Governing Law**

The Notes will be governed by and interpreted in accordance with the laws of the State of New York.

------

**Special Situations Covered by Our Indenture**

***Mergers and Similar Transactions***

We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company. However, we may not take any of these actions unless all the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Where we merge out of existence or sell our assets, the company we merge into or sell to may not be organized under the laws of a foreign country. It must be a corporation organized under the laws of the United States, any State thereof, or the District of Columbia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company we merge into or sell to must agree to be legally responsible for our debt securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merger, sale of assets or other transaction must not cause a default on the securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described below under "- Default and Related Matters - Events of Default - What Is an Event of Default?" A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded.

Further, we may buy substantially all of the assets of another company without complying with any of the foregoing conditions.

***Modification and Waiver of Holders' Contractual Rights***

Under certain circumstances, we can make changes to the Indenture and the securities (including the Notes). Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

*Changes Requiring Approval of Holders.* First, there are changes that cannot be made to the securities without specific approval of holders. The following is a list of those types of changes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the percentage of holders of securities who must consent to a waiver or amendment of the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the rate of interest on any security or change the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the principal due on any security or change the fixed maturity of any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to waive a default in the payment of principal or interest on any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the currency of payment on a security, unless the security provides for payment in a currency that ceases to exist;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of convertible or exchangeable securities, to make changes to conversion or exchange rights that would be adverse to the interests of holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the right of holders to waive an existing default by majority vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the amount of principal or interest payable to holders following a default or change any conversion or exchange rights, or impair the right of holders to sue for payment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change to this list of changes that requires specific approval of holders.

*Changes Requiring a Majority Vote.* The second type of change to the Indenture and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except as set forth in the following paragraph. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain each holder's individual consent to the waiver.

*Changes Not Requiring Approval of Holders.* The third type of change does not require any vote by holders of securities. This type includes, among others, clarifications of ambiguous contract terms, changes to make securities payable in U.S. dollars (if the stated denomination ceases to exist) and other changes that would not materially adversely affect holders of the securities.

------

*Further Details Concerning Voting.* When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent determined on the date of original issuance of these securities.

Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for the applicable holders money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the Indenture. However, the Indenture does not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

***Holders who hold in "street name" and other indirect holders, including holders of any securities issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the Indenture or the securities or request a waiver.***

**Discharge of Our Obligations**

We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for the applicable holders with the trustee and certain other conditions are met. The deposit must be held in trust for the benefit of all direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities.

If we accomplish full discharge, as described above, holders will have to rely solely on the trust deposit for repayment of the securities. Holders could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the trustee and holders against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations.

**Liens on Assets**

The Indenture does not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

**Default and Related Matters**

***Ranking Compared to Other Creditors***

The securities are not secured by any of our property or assets. Accordingly, ownership of securities means each holder is one of our unsecured creditors. The securities are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee has a right to receive payment for its administrative services prior to any payment to security holders after a default.

***Events of Default***

Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

*What Is an Event of Default?* The term "event of default" with respect to any series of securities means any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any interest payment on the securities of such series when it is due, and we do not cure this default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any payment of principal when it is due at the maturity of such series of securities or upon redemption.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to comply with any of our other agreements regarding a particular series of securities or with a supplemental indenture, and after we have been notified of the default by the trustee or holders of 25% in principal amount of the series, we do not cure the default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We file for bankruptcy, or other events in bankruptcy, insolvency or reorganization occur.

***Remedies if an Event of Default Occurs***

Holders and the trustee will have the following remedies if an event of default occurs:

*Acceleration.* If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived.

*Special Duties of Trustee.* If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the Indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

*Other Remedies of Trustee.* If an event of default occurs, the trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the Indenture, including bringing a lawsuit.

*Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests*. The trustee is not required to take any action under the Indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an "indemnity". If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the Indenture.

*Individual Actions Holders May Take if the Trustee Fails to Act.* Before a holder bypasses the trustee and bring such holder's own lawsuit or other formal legal action or take other steps to enforce such holder's rights or protect such holder's interests relating to the securities, the following must occur:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such holder must give the trustee written notice that an event of default has occurred and remains uncured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The holders of 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer indemnity reasonably satisfactory to the trustee against the cost and other liabilities of taking that action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the 60-day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with the request.

However, a holder is entitled at any time to bring an individual lawsuit for the payment of the money due on such holder's security on or after its due date.

***Waiver of Default***

The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on a holder's debt security, however, without such holder's individual approval.

***We Will Give the Trustee Information About Defaults Annually***

Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the Indenture and all the securities under it, or else specifying any default.

------

The trustee may withhold from holders notice of any uncured default, except for payment defaults, if it determines that withholding notice is in holders' interest.

**Holders who hold in "street name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to make or cancel a declaration of acceleration.**

**Regarding the Trustee**

The Bank of New York Mellon Trust Company, N.A. is the trustee under the Indenture. In addition, affiliates of The Bank of New York Mellon Trust Company, N.A. may perform various commercial banking and investment banking services for us and our subsidiaries from time to time in the ordinary course of business.

The Notes are unsecured and unsubordinated obligations and rank *pari passu* with all other indebtedness issued under our Indenture. Each series of Notes constitutes a separate series under the Indenture. The Notes are issued in fully registered form only and in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. Principal and interest payments on the Notes are payable by us in euro. Payments of principal, interest and additional amounts, if any, in respect of the Notes will be made to Euroclear System, Clearstream Banking S.A. or such nominee or common depositary, as the case may be, as registered holder thereof. Under the terms of the Indenture, if the euro ceases to exist when payments on the Notes are due under any circumstances, AT&T may supplement the Indenture to allow for payment in U.S. dollars. The principal and interest payable in U.S. dollars on a Note at maturity, or upon redemption, will be paid by wire transfer of immediately available funds against presentation of a Note at the office of the paying agent.

For purposes of the 1.800% 2026 Notes, 2.350% 2029 Notes, 2.600% 2029 Notes and the 2036 Notes, a business day means any day other than a Saturday or Sunday and that, in the City of New York or the City of London, is not a day on which banking institutions are generally authorized or obligated by law to close, and is a day

------

on which the Trans-European Automated Real-time Gross Settlement Express Transfer (TARGET) System, or any successor thereto, operates.

For purposes of the 2035 Notes, a business day means a business day in the City of New York and London.

**Interest**

The interest rate per annum, annual interest payment date, date of commencement of interest payment and the maturity date of each series of Notes are set forth in the table below. We pay interest on the Notes annually in arrears to the persons in whose names the Notes are registered at the close of business on the business day preceding the respective interest payment date.

| | | | | |
|:---|:---|:---|:---|:---|
| **Series** | **Interest Rate** | **Interest Payment Date** | **Commencement of Interest Payment** | **Maturity Date** |
| 1.800% 2026 Notes | 1.800% | September 4\* | September 4, 2019 | September 5, 2026 |
| 2.350% 2029 Notes | 2.350% | September 4\* | September 4, 2019 | September 5, 2029 |

| 2036 Notes | 3.150% | September 4 | September 4, 2017 | September 4, 2036 |

---

\* We will also pay interest on this series of Notes on its maturity date in an amount calculated for the one day period since the last annual interest payment date.

Interest on the Notes is computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes, to but excluding the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

**Optional Redemption** 

Each series of Notes may be redeemed at any time prior to the applicable Par Call Date (as set forth in the table below), as a whole or in part, at our option, at any time and from time to time on at least 30 days', but not more than 60 days', prior notice sent to the registered address of each holder of the Notes of such series to be redeemed. The redemption price will be calculated by us and will be equal to the greater of (1) 100% of the principal amount of the Notes of such series to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) discounted to the redemption date, on an annual basis (ACTUAL/ACTUAL (ICMA)), at a rate equal to the Treasury Rate (as defined below) plus a number of basis points equal to the applicable Make-Whole Spread (as set forth in the table below). In the case of each of clauses (1) and (2), accrued interest will be payable to the redemption date. Each series of Notes may be redeemed at any time on or after the applicable Par Call Date, as a whole or in part, at our option, at any time and from time to time, on at least 30 days', but not more than 60 days', prior notice sent to the registered address of each holder of the Notes of such series, at a redemption price equal to 100% of the principal amount of such series of Notes to be redeemed. Accrued interest will be payable to the redemption date. We will calculate the redemption price in connection with any redemption hereunder.

------

"*Treasury Rate*" means the price, expressed as a percentage (and, with respect to the 2.600% 2029 Notes, rounded to three decimal places, 0.0005 being rounded upwards), at which the gross redemption yield on the Notes of the applicable series, if they were to be purchased at such price on the third dealing day prior to the date fixed for redemption, would be equal to the gross redemption yield on such dealing day of the applicable Reference Bond (as defined below) on the basis of the middle market price of the Reference Bond prevailing at 11:00 a.m. (London time) on such dealing day as determined by the Company or an investment bank appointed by the Company.

"*Reference Bond*" means, in relation to any Treasury Rate calculation, a German government bond whose maturity is closest to the maturity of the Notes of the applicable series, or if the Company or an investment bank appointed by the Company considers that such similar bond is not in issue, such other German government bond as the Company or an investment bank appointed by the Company, with the advice of three brokers of, and/or market makers in, German government bonds selected by the Company or an investment bank appointed by the Company, determine to be appropriate for determining such Treasury Rate.

"*Remaining Scheduled Payments*" means, with respect to each Note of a series to be redeemed, the remaining scheduled payments of principal of and interest on such Note that would be due after the related redemption date but for the redemption. If that redemption date is not an interest payment date with respect to the applicable series of Notes, the amount of the next succeeding scheduled interest payment on the Notes will be reduced by the amount of interest accrued on the Notes to, but not including, the redemption date.

On and after the redemption date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with a paying agent or the trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date.

In the case of any partial redemption, selection of the Notes of a series to be redeemed will be made by the trustee by lot or (i) with respect to the 1.800% 2026 Notes, 2.350% 2029 Notes and 2036 Notes, pursuant to applicable depositary procedures and (ii) with respect to the 2.600% 2029 Notes and 2035 Notes, by such other method as the trustee in its sole discretion deems to be fair and appropriate.

**Payment of Additional Amounts** 

We will, subject to the exceptions and limitations set forth below, pay as additional interest on the Notes such additional amounts as are necessary so that the net payment by us or our paying agent of the principal of and interest on the Notes to a person that is a United States Alien, after deduction for any present or future tax, assessment or governmental charge of the United States or a political subdivision or taxing authority thereof or therein, imposed by withholding with respect to the payment, will not be less than the amount that would have been payable in respect of the Notes had no withholding or deduction been required. As used herein, "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust.

Our obligation to pay additional amounts shall not apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner, or a fiduciary, settlor, beneficiary or member of the beneficial owner if the beneficial owner is an estate, trust or partnership, or a person holding a power over an estate or trust administered by a fiduciary holder:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) is or was present or engaged in a trade or business in the United States, has or had a permanent establishment in the United States, or has any other present or former connection with the United States or any political subdivision or taxing authority thereof or therein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) is or was a citizen or resident or is or was treated as a resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) is or was a foreign or domestic personal holding company, a passive foreign investment company or a controlled foreign corporation with respect to the United States or is or was a corporation that has accumulated earnings to avoid United States federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) is or was a bank receiving interest described in Section 881(c)(3)(A) of the Internal Revenue Code of 1986, as amended (the "Code"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) is or was an actual or constructive owner of 10% or more of the total combined voting power of all classes of stock of AT&T entitled to vote;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) to any holder that is not the sole beneficial owner of the Notes, or a portion thereof, or that is a fiduciary or partnership, but only to the extent that the beneficial owner, a beneficiary or settlor with respect to the fiduciary, or a member of the partnership would not have been entitled to the payment of an additional amount had such beneficial owner, beneficiary, settlor or member received directly its beneficial or distributive share of the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of the Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) to any tax, assessment or governmental charge that is imposed other than by deduction or withholding by AT&T or a paying agent from the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) to any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that is announced or becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar tax, assessment or governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) to any tax, assessment or other governmental charge any paying agent (which term may include us) must withhold from any payment of principal of or interest on any Note, if such payment can be made without such withholding by any other paying agent; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) in the case of any combination of the above items.

In addition, any amounts to be paid on the Notes will be paid net of any deduction or withholding imposed or required pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code, and no additional amounts will be required to be paid on account of any such deduction or withholding.

The Notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable. Except as specifically provided under this heading "-Payment of Additional Amounts" and under the heading "-Redemption Upon a Tax Event," we do not have to make any payment with respect to any tax, assessment or governmental charge imposed by any government or a political subdivision or taxing authority.

Any reference in the terms of the Notes of each series to any amounts in respect of the Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

**Redemption Upon a Tax Event**

If (a) we become or will become obligated to pay additional amounts with respect to any Notes as described herein under the heading "-Payment of Additional Amounts" as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein), or any change in, or amendments to, any official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective, on or after the date set forth in the table below with respect to the relevant series of Notes or (b) a taxing authority of the United States takes an action on or after the date set forth in the table below with respect to the relevant series of Notes, whether or not with respect to us or any of our affiliates, that results in a substantial probability that we will or may be required to pay such additional amounts, then we may, at our option, redeem, as a whole, but not in part, the Notes on any interest payment date on not less than 30 nor more than 60 calendar days' prior notice, at a redemption price equal to 100% of their principal amount, together with interest accrued thereon to, but not including, the date fixed for redemption. No redemption pursuant to (b) above may be made unless we shall have received an opinion of independent counsel to the effect that an act taken by a taxing authority of the United States results in a substantial probability that we will or may be required to pay the additional amounts described herein under the heading "-Payment of Additional Amounts" and we shall have delivered to the trustee a certificate, signed by a duly authorized officer, stating that based on such opinion we are entitled to redeem the Notes pursuant to their terms.

**Further Issues** 

We may from time to time, without notice to or the consent of the holders of any series of the Notes, create and issue further notes ranking equally and ratably with such series in all respects, or in all respects except for the payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date of those further notes. Any further notes will have the same terms as to status, redemption or otherwise as, and will be fungible for United States federal income tax purposes with, the Notes of the applicable series. Any further notes shall be issued pursuant to a resolution of our board of directors, a supplement to the Indenture, or under an officers' certificate pursuant to the Indenture.

**Governing Law**

The Notes will be governed by and interpreted in accordance with the laws of the State of New York.

**Special Situations Covered by Our Indenture**

***Mergers and Similar Transactions***

We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company. However, we may not take any of these actions unless all the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Where we merge out of existence or sell our assets, the company we merge into or sell to may not be organized under the laws of a foreign country. It must be a corporation organized under the laws of the United States, any State thereof, or the District of Columbia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company we merge into or sell to must agree to be legally responsible for our debt securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merger, sale of assets or other transaction must not cause a default on the securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described below under "- Default and Related Matters - Events of Default - What Is an Event of Default?" A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded.

Further, we may buy substantially all of the assets of another company without complying with any of the foregoing conditions.

***Modification and Waiver of Holders' Contractual Rights***

Under certain circumstances, we can make changes to the Indenture and the securities (including the Notes). Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

*Changes Requiring Approval of Holders.* First, there are changes that cannot be made to the securities without specific approval of holders. The following is a list of those types of changes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the percentage of holders of securities who must consent to a waiver or amendment of the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the rate of interest on any security or change the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the principal due on any security or change the fixed maturity of any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to waive a default in the payment of principal or interest on any security;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the currency of payment on a security, unless the security provides for payment in a currency that ceases to exist;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of convertible or exchangeable securities, to make changes to conversion or exchange rights that would be adverse to the interests of holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the right of holders to waive an existing default by majority vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the amount of principal or interest payable to holders following a default or change any conversion or exchange rights, or impair the right of holders to sue for payment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change to this list of changes that requires specific approval of holders.

*Changes Requiring a Majority Vote.* The second type of change to the Indenture and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except as set forth in the following paragraph. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain each holder's individual consent to the waiver.

*Changes Not Requiring Approval of Holders.* The third type of change does not require any vote by holders of securities. This type includes, among others, clarifications of ambiguous contract terms, changes to make securities payable in U.S. dollars (if the stated denomination ceases to exist) and other changes that would not materially adversely affect holders of the securities.

*Further Details Concerning Voting.* When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent determined on the date of original issuance of these securities.

Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for the applicable holders money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the Indenture. However, the Indenture does not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

***Holders who hold in "street name" and other indirect holders, including holders of any securities issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the Indenture or the securities or request a waiver.***

**Discharge of Our Obligations**

We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for the applicable holders with the trustee and certain other conditions are met. The deposit must be held in trust for the benefit of all direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities.

If we accomplish full discharge, as described above, holders will have to rely solely on the trust deposit for repayment of the securities. Holders could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the trustee and holders against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations.

**Liens on Assets**

The Indenture does not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

**Default and Related Matters**

***Ranking Compared to Other Creditors***

The securities are not secured by any of our property or assets. Accordingly, ownership of securities means each holder is one of our unsecured creditors. The securities are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee has a right to receive payment for its administrative services prior to any payment to security holders after a default.

***Events of Default***

Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

*What Is an Event of Default?* The term "event of default" with respect to any series of securities means any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any interest payment on the securities of such series when it is due, and we do not cure this default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any payment of principal when it is due at the maturity of such series of securities or upon redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to comply with any of our other agreements regarding a particular series of securities or with a supplemental indenture, and after we have been notified of the default by the trustee or holders of 25% in principal amount of the series, we do not cure the default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We file for bankruptcy, or other events in bankruptcy, insolvency or reorganization occur.

***Remedies if an Event of Default Occurs***

Holders and the trustee will have the following remedies if an event of default occurs:

*Acceleration.* If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived.

*Special Duties of Trustee.* If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the Indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

*Other Remedies of Trustee.* If an event of default occurs, the trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the Indenture, including bringing a lawsuit.

*Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests*. The trustee is not required to take any action under the Indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an "indemnity". If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the Indenture.

*Individual Actions Holders May Take if the Trustee Fails to Act.* Before a holder bypasses the trustee and brings such holder's own lawsuit or other formal legal action or take other steps to enforce such holder's rights or protect such holder's interests relating to the securities, the following must occur:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such holder must give the trustee written notice that an event of default has occurred and remains uncured.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The holders of 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer indemnity reasonably satisfactory to the trustee against the cost and other liabilities of taking that action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the 60-day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with the request.

However, a holder is entitled at any time to bring an individual lawsuit for the payment of the money due on such holder's security on or after its due date.

***Waiver of Default***

The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on a holder's debt security, however, without such holder's individual approval.

***We Will Give the Trustee Information About Defaults Annually***

Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the Indenture and all the securities under it, or else specifying any default.

The trustee may withhold from holders notice of any uncured default, except for payment defaults, if it determines that withholding notice is in holders' interest.

**Holders who hold in "street name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to make or cancel a declaration of acceleration.**

**Regarding the Trustee**

The Bank of New York Mellon Trust Company, N.A. is the trustee under the Indenture. In addition, affiliates of The Bank of New York Mellon Trust Company, N.A. may perform various commercial banking and investment banking services for us and our subsidiaries from time to time in the ordinary course of business.

The Notes are unsecured and unsubordinated obligations and rank *pari passu* with all other indebtedness issued under our Indenture. Each series of Notes constitutes a separate series under the Indenture. The Notes are issued in fully registered form only and in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. Principal and interest payments on the Notes are payable by us in euro. Payments of principal, interest and additional amounts, if any, in respect of the Notes will be made to Euroclear System, Clearstream Banking S.A. or such nominee or common depositary, as the case may be, as registered holder thereof. Under the terms of the Indenture, if the euro ceases to exist when payments on the Notes are due under any circumstances, AT&T may supplement the Indenture to allow for payment in U.S. dollars. The principal and interest payable in U.S. dollars on a Note at maturity, or upon redemption, will be paid by wire transfer of immediately available funds against presentation of a Note at the office of the paying agent.

For purposes of the Notes, a business day means any day that is not a Saturday or Sunday and that, in the City of New York or the City of London, is not a day on which banking institutions are generally authorized or obligated by law to close.

**Interest**

The 0.250% 2026 Notes bear interest at the rate of 0.250% per annum, the 2028 Notes bear interest at the rate of 1.600% per annum, the 2030 Notes bear interest at the rate of 0.800% per annum, the 2.050% 2032 Notes bear interest at the rate of 2.050% per annum, the 2038 Notes bear interest at the rate of 2.600% per annum and the 2039 Notes bear interest at the rate of 1.800% per annum.

We pay interest on the 0.250% 2026 Notes and the 2030 Notes annually in arrears on each March 4, commencing on March 4, 2020, to the persons in whose names the 0.250% 2026 Notes and the 2030 Notes are registered at the close of business on the business day preceding the interest payment date. We pay interest on the 2028 Notes, the 2.050% 2032 Notes and the 2038 Notes annually in arrears on each May 19, commencing on May 19, 2021, to the persons in whose names the 2028 Notes, the 2.050% 2032 Notes and the 2038 Notes are registered at the close of business on the business day preceding the interest payment date. We pay interest on the 2039 Notes annually in arrears on each September 14, commencing on September 14, 2020, to the persons in whose names the 2039 Notes are registered at the close of business on the business day preceding the interest payment date.

The 0.250% 2026 Notes will mature on March 4, 2026, the 2028 Notes will mature on May 19, 2028, the 2030 Notes will mature on March 4, 2030, the 2.050% 2032 Notes will mature on May 19, 2032, the 2038 Notes will mature on May 19, 2038 and the 2039 Notes will mature on September 14, 2039.

Interest on the Notes will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes (or September 11, 2019 with respect to the 0.250% 2026 Notes, the 2030 Notes and 2039 Notes and May 27, 2020 with respect to the 2028 Notes, the 2.050% 2032 Notes and the 2038 Notes, if no interest has been paid on the Notes), to but excluding the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

------

Because the first payment of interest on the 2039 Notes is more than one year from the issue date of the 2039 Notes, the 2039 Notes will be treated for U.S. federal income tax purposes as issued with original issue discount ("OID") in an amount equal to the excess of the principal amount and interest payments on the 2039 Notes over the issue price for the 2039 Notes. Accordingly, United States holders of the 2039 Notes will generally be required to accrue such OID for U.S. tax purposes on a constant yield basis over the term of the 2039 Notes even if the holder is otherwise subject to the cash basis method of tax accounting. Such holders, however, will generally not be required to include the stated interest payments on the 2039 Notes in income for U.S. tax purposes.

**Optional Redemption**

At any time prior to the applicable Par Call Date (as set forth in the table below), (i) the 0.250% 2026 Notes, the 2030 Notes and the 2039 Notes may be redeemed, as a whole or in part, at our option, at any time and from time to time, on at least 30 days', but not more than 60 days', prior notice sent to the registered address of each holder of the Notes of such series to be redeemed, and (ii) the 2028 Notes, the 2.050% 2032 Notes and the 2038 Notes may be redeemed, as a whole or in part, at our option, at any time and from time to time, on at least 10 days', but not more than 40 days', prior notice sent to the registered address of each holder of the Notes of such series to be redeemed. In each case, the redemption price will be calculated by us and will be equal to the greater of (1) 100% of the principal amount of the Notes of such series to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) discounted to the redemption date, on an annual basis (ACTUAL/ACTUAL (ICMA)), at a rate equal to the Treasury Rate (as defined below) plus a number of basis points equal to the applicable Make-Whole Spread (as set forth in the table below). In the case of each of clauses (1) and (2), accrued interest will be payable to the redemption date. At any time on or after the applicable Par Call Date (as set forth in the table below), (i) the 0.250% 2026 Notes, the 2030 Notes and the 2039 Notes may be redeemed, as a whole or in part, at our option, at any time and from time to time, on at least 30 days', but not more than 60 days', prior notice sent to the registered address of each holder of the Notes of such series to be redeemed, and (ii) the 2028 Notes, the 2.050% 2032 Notes and the 2038 Notes may be redeemed, as a whole or in part, at our option, at any time and from time to time, on at least 10 days', but not more than 40 days', prior notice sent to the registered address of each holder of the Notes of such series to be redeemed, in each case, at a redemption price equal to 100% of the principal amount of such series of Notes to be redeemed.

"*Treasury Rate*" means the price, expressed as a percentage, at which the gross redemption yield on the Notes of the applicable series, if they were to be purchased at such price on the third dealing day prior to the date fixed for redemption, would be equal to the gross redemption yield on such dealing day of the applicable Reference Bond (as defined below) on the basis of the middle market price of the Reference Bond prevailing at 11:00 a.m. (London time) on such dealing day as determined by the Company or an investment bank appointed by the Company.

"*Reference Bond*" means, in relation to any Treasury Rate calculation, a German government bond whose maturity is closest to the maturity of the Notes of the applicable series, or if the Company or an investment bank appointed by the Company considers that such similar bond is not in issue, such other German government bond as the Company or an investment bank appointed by the Company, with the advice of three brokers of, and/or market makers in, German government bonds selected by the Company or an investment bank appointed by the Company, determine to be appropriate for determining such Treasury Rate.

"*Remaining Scheduled Payments*" means, with respect to each Note of a series to be redeemed, the remaining scheduled payments of principal and interest on such Note that, but for the redemption, would be due

------

after the related redemption date through the applicable Par Call Date, assuming the applicable series of Notes matured on the Par Call Date (not including any portion of payments of interest accrued as of the redemption date). If that redemption date is not an interest payment date with respect to the applicable series of Notes, the amount of the next succeeding scheduled interest payment on the Notes will be reduced by the amount of interest accrued on the Notes to the redemption date.

On and after the redemption date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with our paying agent or the trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date.

In the case of any partial redemption, selection of the Notes of a series to be redeemed will be made by the trustee by lot or pursuant to applicable depositary procedures.

**Payment of Additional Amounts**

We will, subject to the exceptions and limitations set forth below, pay as additional interest on the Notes such additional amounts as are necessary so that the net payment by us or our paying agent of the principal of and interest on the Notes to a person that is a United States Alien, after deduction for any present or future tax, assessment or governmental charge of the United States or a political subdivision or taxing authority thereof or therein, imposed by withholding with respect to the payment, will not be less than the amount that would have been payable in respect of the Notes had no withholding or deduction been required. As used herein, "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust.

Our obligation to pay additional amounts shall not apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner, or a fiduciary, settlor, beneficiary or member of the beneficial owner if the beneficial owner is an estate, trust or partnership, or a person holding a power over an estate or trust administered by a fiduciary holder:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) is or was present or engaged in a trade or business in the United States, has or had a permanent establishment in the United States, or has any other present or former connection with the United States or any political subdivision or taxing authority thereof or therein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) is or was a foreign or domestic personal holding company, a passive foreign investment company or a controlled foreign corporation with respect to the United States or is or was a corporation that has accumulated earnings to avoid United States federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) is or was a bank receiving interest described in Section 881(c)(3)(A) of the Internal Revenue Code of 1986, as amended (the "Code"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) is or was an actual or constructive owner of 10% or more of the total combined voting power of all classes of stock of AT&T entitled to vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) to any holder that is not the sole beneficial owner of the Notes, or a portion thereof, or that is a fiduciary or partnership, but only to the extent that the beneficial owner, a beneficiary or settlor with respect to the fiduciary, or a member of the partnership would not have been entitled to the payment of an additional amount had such beneficial owner, beneficiary, settlor or member received directly its beneficial or distributive share of the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of the Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) to any tax, assessment or governmental charge that is imposed other than by deduction or withholding by AT&T or a paying agent from the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) to any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that is announced or becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar tax, assessment or governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) to any tax, assessment or other governmental charge any paying agent (which term may include us) must withhold from any payment of principal of or interest on any Note, if such payment can be made without such withholding by any other paying agent; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) in the case of any combination of the above items.

In addition, any amounts to be paid on the Notes will be paid net of any deduction or withholding imposed or required pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code, and no additional amounts will be required to be paid on account of any such deduction or withholding.

The Notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable. Except as specifically provided under this heading "- Payment of Additional Amounts" and under the heading "- Redemption Upon a Tax Event," we do not have to make any payment with respect to any tax, assessment or governmental charge imposed by any government or a political subdivision or taxing authority.

Any reference in the terms of the Notes of each series to any amounts in respect of the Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

If (a) we become or will become obligated to pay additional amounts with respect to any Notes as described herein under the heading "- Payment of Additional Amounts" as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein), or any change in, or amendments to, any official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective, on or after the date set forth in the table below with respect to the relevant series of Notes or (b) a taxing authority of the United States takes an action on or after the date set forth in the table below with respect to the relevant series of Notes, whether or not with respect to us or any of our affiliates, that results in a substantial probability that we will or may be required to pay such additional amounts, then we may, at our option, redeem, as a whole, but not in part, the Notes on any interest payment date on not less than 30 nor more than 60 calendar days' prior notice with respect to the 0.250% 2026 Notes, the 2030 Notes, and the 2039 Notes and not less than 10 nor more than 40 calendar days' prior notice with respect to the 2028 Notes, the 2.050% 2032 Notes and the 2038 Notes, at a redemption price equal to 100% of their principal amount, together with interest accrued thereon to the date fixed for redemption. No redemption pursuant to (b) above may be made unless we shall have received an opinion of independent counsel to the effect that an act taken by a taxing authority of the United States results in a substantial probability that we will or may be required to pay the additional amounts described herein under the heading "- Payment of Additional Amounts" and we shall have delivered to the trustee a certificate, signed by a duly authorized officer, stating that based on such opinion we are entitled to redeem the Notes pursuant to their terms.

**Further Issues**

We may from time to time, without notice to or the consent of the holders of any series of the Notes, create and issue further notes ranking equally and ratably with such series in all respects, or in all respects except for the

------

payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date of those further notes. Any further notes will have the same terms as to status, redemption or otherwise as, and will be fungible for United States federal income tax purposes with, the Notes of the applicable series. Any further notes shall be issued pursuant to a resolution of our board of directors, a supplement to the Indenture, or under an officers' certificate pursuant to the Indenture.

**Governing Law**

The Notes will be governed by and interpreted in accordance with the laws of the State of New York.

**Special Situations Covered by Our Indenture**

***Mergers and Similar Transactions***

We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company. However, we may not take any of these actions unless all the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Where we merge out of existence or sell our assets, the company we merge into or sell to may not be organized under the laws of a foreign country. It must be a corporation organized under the laws of the United States, any State thereof, or the District of Columbia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company we merge into or sell to must agree to be legally responsible for our debt securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merger, sale of assets or other transaction must not cause a default on the securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described below under "- Default and Related Matters - Events of Default - What Is an Event of Default?" A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded.

Further, we may buy substantially all of the assets of another company without complying with any of the foregoing conditions.

***Modification and Waiver of Holders' Contractual Rights***

Under certain circumstances, we can make changes to the Indenture and the securities (including the Notes). Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

*Changes Requiring Approval of Holders.* First, there are changes that cannot be made to the securities without specific approval of holders. The following is a list of those types of changes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the percentage of holders of securities who must consent to a waiver or amendment of the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the rate of interest on any security or change the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the principal due on any security or change the fixed maturity of any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to waive a default in the payment of principal or interest on any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the currency of payment on a security, unless the security provides for payment in a currency that ceases to exist;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of convertible or exchangeable securities, to make changes to conversion or exchange rights that would be adverse to the interests of holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the right of holders to waive an existing default by majority vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the amount of principal or interest payable to holders following a default or change any conversion or exchange rights, or impair the right of holders to sue for payment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change to this list of changes that requires specific approval of holders.

------

*Changes Requiring a Majority Vote.* The second type of change to the Indenture and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except as set forth in the following paragraph. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain each holder's individual consent to the waiver.

*Changes Not Requiring Approval of Holders.* The third type of change does not require any vote by holders of securities. This type includes, among others, clarifications of ambiguous contract terms, changes to make securities payable in U.S. dollars (if the stated denomination ceases to exist) and other changes that would not materially adversely affect holders of the securities.

*Further Details Concerning Voting.* When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent determined on the date of original issuance of these securities.

Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for the applicable holders money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the Indenture. However, the Indenture does not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

***Holders who hold in "street name" and other indirect holders, including holders of any securities issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the Indenture or the securities or request a waiver.***

**Discharge of Our Obligations**

We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for the applicable holders with the trustee and certain other conditions are met. The deposit must be held in trust for the benefit of all direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities.

If we accomplish full discharge, as described above, holders will have to rely solely on the trust deposit for repayment of the securities. Holders could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the trustee and holders against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations.

**Liens on Assets**

The Indenture does not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

**Default and Related Matters**

***Ranking Compared to Other Creditors***

The securities are not secured by any of our property or assets. Accordingly, ownership of securities means each holder is one of our unsecured creditors. The securities are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee has a right to receive payment for its administrative services prior to any payment to security holders after a default.

***Events of Default***

Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

------

*What Is an Event of Default?* The term "event of default" with respect to any series of securities means any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any interest payment on the securities of such series when it is due, and we do not cure this default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any payment of principal when it is due at the maturity of such series of securities or upon redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to comply with any of our other agreements regarding a particular series of securities or with a supplemental indenture, and after we have been notified of the default by the trustee or holders of 25% in principal amount of the series, we do not cure the default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We file for bankruptcy, or other events in bankruptcy, insolvency or reorganization occur.

***Remedies if an Event of Default Occurs***

Holders and the trustee will have the following remedies if an event of default occurs:

*Acceleration.* If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived.

*Special Duties of Trustee.* If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the Indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

*Other Remedies of Trustee.* If an event of default occurs, the trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the Indenture, including bringing a lawsuit.

*Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests*. The trustee is not required to take any action under the Indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an "indemnity". If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the Indenture.

*Individual Actions Holders May Take if the Trustee Fails to Act.* Before a holder bypasses the trustee and brings such holder's own lawsuit or other formal legal action or take other steps to enforce such holder's rights or protect such holder's interests relating to the securities, the following must occur:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such holder must give the trustee written notice that an event of default has occurred and remains uncured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The holders of 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer indemnity reasonably satisfactory to the trustee against the cost and other liabilities of taking that action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the 60-day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with the request.

However, a holder is entitled at any time to bring an individual lawsuit for the payment of the money due on such holder's security on or after its due date.

***Waiver of Default***

------

The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on a holder's debt security, however, without such holder's individual approval.

***We Will Give the Trustee Information About Defaults Annually***

Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the Indenture and all the securities under it, or else specifying any default.

The trustee may withhold from holders notice of any uncured default, except for payment defaults, if it determines that withholding notice is in holders' interest.

**Holders who hold in "street name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to make or cancel a declaration of acceleration.**

**Regarding the Trustee** 

The Bank of New York Mellon Trust Company, N.A. is the trustee under the Indenture. In addition, affiliates of The Bank of New York Mellon Trust Company, N.A. may perform various commercial banking and investment banking services for us and our subsidiaries from time to time in the ordinary course of business.

The Notes are unsecured and unsubordinated obligations and rank pari passu with all other indebtedness issued under our Indenture. Each series of Notes constitutes a separate series under the Indenture. The Notes are issued in fully registered form only and in minimum denominations of $100,000 and integral multiples of $1,000 thereafter. Principal and interest payments on the Notes registered in the name of the depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner.

For purposes of the Notes, a business day means a business day in The City of New York and Taipei, Taiwan.

**Interest**

The 2049 Notes bear interest at the rate of 4.000% per annum, the 4.250% 2050 Notes bear interest at the rate of 4.250% per annum and the 3.750% 2050 Notes bear interest at the rate of 3.750% per annum.

We pay interest on the 2049 Notes in arrears on each June 1 and December 1, commencing on June 1, 2020, to the persons in whose names the 2049 Notes are registered at the close of business on the fifteenth day preceding the interest payment date. We pay interest on the 4.250% 2050 Notes in arrears on each March 1 and September 1, commencing on March 1, 2020, to the persons in whose names the 4.250% 2050 Notes are registered at the close of business on the fifteenth day preceding the interest payment date. We pay interest on the 3.750% 2050 Notes in arrears on each March 1 and September 1, commencing on September 1, 2020, to the persons in whose names the 3.750% 2050 Notes are registered at the close of business on the fifteenth day preceding the interest payment date.

The 2049 Notes will mature on June 1, 2049, the 4.250% 2050 Notes will mature on March 1, 2050 and the 3.750% 2050 Notes will mature on September 1, 2050.

Interest on the Notes is computed on the basis of the number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes, to but excluding the next scheduled interest payment date (such number of days being calculated on the basis of a year of 360 days with 12 30-day months). This payment convention is referred to as 30/360.

**Optional Redemption** 

We have the option to redeem all, but not less than all, of each series of the Notes then outstanding on the applicable Redemption Date (as set forth in the table below). In addition, on the first Redemption Date on which we opt to redeem any series of the Notes, we also have the option to instead only redeem 50% of the aggregate principal amount of such series of Notes then outstanding. If we opt to redeem 50% of the aggregate principal amount of a series of the Notes then outstanding on a Redemption Date, any remaining Notes of such series can be redeemed at our option on a future Redemption Date in whole but not in part. Any redemption described in this paragraph must be on not less than 10 nor more than 40 days' notice and will be at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest to the date of redemption. We will calculate the redemption price in connection with any redemption hereunder.

------

---

| | |
|:---|:---|
| **Series** | **Redemption Date** |
| 2049 Notes | Each June 1 on or after June 1, 2025 |
| 4.250% 2050 Notes | Each March 1 on or after March 1, 2025 |
| 3.750% 2050 Notes | Each September 1 on or after September 1, 2025 |

---

On and after the redemption date, interest will cease to accrue on the Notes or the portion of the Notes called for redemption unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with our paying agent or the trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date.

If less than all of any series of the Notes are to be redeemed, the Notes to be redeemed shall be selected pro rata or in accordance with applicable depositary procedures.

**Payment of Additional Amounts** 

We will, subject to the exceptions and limitations set forth below, pay as additional interest on the Notes such additional amounts as are necessary so that the net payment by us or our paying agent of the principal of and interest on the Notes to a person that is a United States Alien, after deduction for any present or future tax, assessment or governmental charge of the United States or a political subdivision or taxing authority thereof or therein, imposed by withholding with respect to the payment, will not be less than the amount that would have been payable in respect of the Notes had no withholding or deduction been required. As used herein, "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust.

Our obligation to pay additional amounts shall not apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner, or a fiduciary, settlor, beneficiary or member of the beneficial owner if the beneficial owner is an estate, trust or partnership, or a person holding a power over an estate or trust administered by a fiduciary holder:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) is or was present or engaged in a trade or business in the United States, has or had a permanent establishment in the United States, or has any other present or former connection with the United States or any political subdivision or taxing authority thereof or therein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) is or was a citizen or resident or is or was treated as a resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) is or was a foreign or domestic personal holding company, a passive foreign investment company or a controlled foreign corporation with respect to the United States or is or was a corporation that has accumulated earnings to avoid United States federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) is or was a bank receiving interest described in Section 881(c)(3)(A) of the Internal Revenue Code of 1986, as amended (the "Code"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) is or was an actual or constructive owner of 10% or more of the total combined voting power of all classes of stock of AT&T entitled to vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) to any holder that is not the sole beneficial owner of the Notes, or a portion thereof, or that is a fiduciary or partnership, but only to the extent that the beneficial owner, a beneficiary or settlor with respect

to the fiduciary, or a member of the partnership would not have been entitled to the payment of an additional amount had such beneficial owner, beneficiary, settlor or member received directly its beneficial or distributive share of the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of the Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) to any tax, assessment or governmental charge that is imposed other than by deduction or withholding by AT&T or a paying agent from the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) to any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that is announced or becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar tax, assessment or governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) to any tax, assessment or other governmental charge any paying agent (which term may include us) must withhold from any payment of principal of or interest on any Note, if such payment can be made without such withholding by any other paying agent; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) in the case of any combination of the above items.

In addition, any amounts to be paid on the Notes will be paid net of any deduction or withholding imposed or required pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code, and no additional amounts will be required to be paid on account of any such deduction or withholding.

The Notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable. Except as specifically provided under this heading "-Payment of Additional Amounts" and under the heading "-Redemption Upon a Tax Event," we do not have to make any payment with respect to any tax, assessment or governmental charge imposed by any government or a political subdivision or taxing authority.

Any reference in the terms of the Notes of each series to any amounts in respect of the Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

**Redemption Upon a Tax Event**

If (a) we become or will become obligated to pay additional amounts with respect to any Notes as described herein under the heading "-Payment of Additional Amounts" as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein), or any change in, or amendments to, any official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective, on or after the date set forth in the table below with respect to the relevant series of Notes or (b) a taxing authority of the United States takes an action on or after the date set forth in the table below with respect to the relevant series of Notes, whether or not with respect to us or any of our affiliates, that results in a substantial probability that we will or may be required to pay such additional amounts, then we may, at our option, redeem, as a whole, but not in part, the Notes on any interest payment date on not less than 10 nor more than 40 calendar days' prior notice, at a redemption price equal to 100% of their principal amount, together with interest accrued thereon to the date fixed for redemption. No redemption pursuant to (b) above may be made unless we shall have received an opinion of independent counsel to the effect that an act taken by a taxing authority of the United States results in a substantial probability that we will or may be required to pay the additional amounts described herein under the heading "-Payment of Additional Amounts" and we shall have delivered to the trustee a certificate, signed by a duly authorized officer, stating that based on such opinion we are entitled to redeem the Notes pursuant to their terms.

**Further Issues** 

We may from time to time, without notice to or the consent of the holders of any series of the Notes, create and issue further notes ranking equally and ratably with such Notes in all respects, or in all respects except for the payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date

------

of those further notes. Any further notes will have the same terms as to status, redemption or otherwise, and, to the extent permitted by applicable authorities in the Republic of China and subject to the receipt of all necessary regulatory and listing approvals from such authorities, including but not limited to the Taipei Exchange and the Taiwan Securities Association, will be fungible for United States federal income tax purposes with, the Notes of the applicable series. Any further notes shall be issued pursuant to a resolution of our board of directors, a supplement to the Indenture, or under an officers' certificate pursuant to the Indenture.

**Notices**

Notices to holders of the Notes will be given only to the depositary, in accordance with its applicable policies as in effect from time to time.

**Prescription Period**

Any money that we deposit with the trustee or any paying agent for the payment of principal or any interest on a Note that remains unclaimed for two years after the date upon which the principal and interest are due and payable will be repaid to us upon our request unless otherwise required by mandatory provisions of any applicable unclaimed property law. After that time, unless otherwise required by mandatory provisions of any unclaimed property law, the holder of the Note will be able to seek any payment to which that holder may be entitled to collect only from us.

**Governing Law**

The Notes are governed by and interpreted in accordance with the laws of the State of New York.

**Special Situations Covered by Our Indenture**

***Mergers and Similar Transactions***

We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company. However, we may not take any of these actions unless all the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Where we merge out of existence or sell our assets, the company we merge into or sell to may not be organized under the laws of a foreign country. It must be a corporation organized under the laws of the United States, any State thereof, or the District of Columbia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company we merge into or sell to must agree to be legally responsible for our debt securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merger, sale of assets or other transaction must not cause a default on the securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described below under "- Default and Related Matters - Events of Default - What Is an Event of Default?" A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded.

Further, we may buy substantially all of the assets of another company without complying with any of the foregoing conditions.

***Modification and Waiver of Holders' Contractual Rights***

Under certain circumstances, we can make changes to the Indenture and the securities (including the Notes). Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

*Changes Requiring Approval of Holders.* First, there are changes that cannot be made to the securities without specific approval of holders. The following is a list of those types of changes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the percentage of holders of securities who must consent to a waiver or amendment of the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the rate of interest on any security or change the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the principal due on any security or change the fixed maturity of any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to waive a default in the payment of principal or interest on any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the currency of payment on a security, unless the security provides for payment in a currency that ceases to exist;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of convertible or exchangeable securities, to make changes to conversion or exchange rights that would be adverse to the interests of holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the right of holders to waive an existing default by majority vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the amount of principal or interest payable to holders following a default or change any conversion or exchange rights, or impair the right of holders to sue for payment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change to this list of changes that requires specific approval of holders.

*Changes Requiring a Majority Vote.* The second type of change to the Indenture and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except as set forth in the following paragraph. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain each holder's individual consent to the waiver.

*Changes Not Requiring Approval of Holders.* The third type of change does not require any vote by holders of securities. This type includes, among others, clarifications of ambiguous contract terms, changes to make securities payable in U.S. dollars (if the stated denomination ceases to exist) and other changes that would not materially adversely affect holders of the securities.

*Further Details Concerning Voting.* When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent determined on the date of original issuance of these securities.

Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for the applicable holders money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the Indenture. However, the Indenture does not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

***Holders who hold in "street name" and other indirect holders, including holders of any securities issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the Indenture or the securities or request a waiver.***

**Discharge of Our Obligations**

We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for the applicable holders with the trustee and certain other conditions are met. The deposit must be held in trust for the benefit of all direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities.

If we accomplish full discharge, as described above, holders will have to rely solely on the trust deposit for repayment of the securities. Holders could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the trustee and holders against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations.

**Liens on Assets**

The Indenture does not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

**Default and Related Matters**

------

***Ranking Compared to Other Creditors***

The securities are not secured by any of our property or assets. Accordingly, ownership of securities means each holder is one of our unsecured creditors. The securities are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee has a right to receive payment for its administrative services prior to any payment to security holders after a default.

***Events of Default***

Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

*What Is an Event of Default?* The term "event of default" with respect to any series of securities means any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any interest payment on the securities of such series when it is due, and we do not cure this default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any payment of principal when it is due at the maturity of such series of securities or upon redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to comply with any of our other agreements regarding a particular series of securities or with a supplemental indenture, and after we have been notified of the default by the trustee or holders of 25% in principal amount of the series, we do not cure the default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We file for bankruptcy, or other events in bankruptcy, insolvency or reorganization occur.

***Remedies if an Event of Default Occurs***

Holders and the trustee will have the following remedies if an event of default occurs:

*Acceleration.* If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived.

*Special Duties of Trustee.* If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the Indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

*Other Remedies of Trustee.* If an event of default occurs, the trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the Indenture, including bringing a lawsuit.

*Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests*. The trustee is not required to take any action under the Indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an "indemnity". If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the Indenture.

*Individual Actions Holders May Take if the Trustee Fails to Act.* Before a holder bypasses the trustee and brings such holder's own lawsuit or other formal legal action or take other steps to enforce such holder's rights or protect such holder's interests relating to the securities, the following must occur:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such holder must give the trustee written notice that an event of default has occurred and remains uncured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The holders of 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer indemnity reasonably satisfactory to the trustee against the cost and other liabilities of taking that action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the 60-day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with the request.

However, a holder is entitled at any time to bring an individual lawsuit for the payment of the money due on such holder's security on or after its due date.

***Waiver of Default***

The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on a holder's debt security, however, without such holder's individual approval.

***We Will Give the Trustee Information About Defaults Annually***

Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the Indenture and all the securities under it, or else specifying any default.

The trustee may withhold from holders notice of any uncured default, except for payment defaults, if it determines that withholding notice is in holders' interest.

**Holders who hold in "street name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to make or cancel a declaration of acceleration.**

**Regarding the Trustee**

The Bank of New York Mellon Trust Company, N.A. is the trustee under the Indenture. In addition, affiliates of The Bank of New York Mellon Trust Company, N.A. may perform various commercial banking and investment banking services for us and our subsidiaries from time to time in the ordinary course of business.

**DESCRIPTION OF THE 5.350% GLOBAL NOTES DUE 2066**

*The following summary of AT&T's above referenced debt securities is based on and qualified by the indenture, dated as of May 15, 2013, with The Bank of New York Mellon Trust Company, N.A., acting as trustee (the "Indenture") and the 5.350% Global Notes due 2066 (the "Notes").

The Notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• were issued in an aggregate initial principal amount of $1,322,500,000, which remains the amount outstanding, subject to our ability to issue additional Notes which may be of the same series as the Notes as described under "- Further Issues";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mature on November 1, 2066;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• bear interest at the rate of 5.350% per annum, payable quarterly in arrears;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are repayable at par at maturity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are redeemable by us at the time described below under "- Optional Redemption" and in connection with certain tax events as described below under "- Redemption Upon a Tax Event"; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are not subject to any sinking fund.

The Notes are unsecured and unsubordinated obligations and rank pari passu with all other indebtedness issued under our Indenture. The Notes are issued in fully registered form only and in minimum denominations of $25 and integral multiples of $25 thereafter. Principal and interest payments on the Notes registered in the name of

------

the depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the global notes.

For purposes of the Notes, a business day means a business day in the City of New York.

**Interest**

The Notes bear interest at the rate of 5.350% per annum.

We pay interest on the Notes on each February 1, May 1, August 1 and November 1, commencing on February 1, 2018, to the persons in whose names the Notes are registered at the close of business on the fifteenth day preceding the respective interest payment date.

The Notes will mature on November 1, 2066.

**Optional Redemption** 

We may, at our option, redeem the Notes, in whole or in part, at any time and from time to time on or after November 1, 2022, on at least 30 days', but not more than 60 days', prior notice mailed (or otherwise transmitted in accordance with The Depository Trust Company ("DTC") procedures) to the registered address of each holder of the Notes to be redeemed. The redemption price will be equal to 100% of the principal amount of the Notes to be redeemed plus accrued but unpaid interest to, but excluding, the redemption date.

On and after the redemption date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption, unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with our paying agent or the trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date. In the case of any partial redemption, selection of the Notes of a series to be redeemed will be made in accordance with applicable procedures of DTC.

**Payment of Additional Amounts** 

We will, subject to the exceptions and limitations set forth below, pay as additional interest on the Notes such additional amounts as are necessary so that the net payment by us or our paying agent of the principal of and interest on the Notes to a person that is a United States Alien, after deduction for any present or future tax, assessment or governmental charge of the United States or a political subdivision or taxing authority thereof or therein, imposed by withholding with respect to the payment, will not be less than the amount that would have been payable in respect of the Notes had no withholding or deduction been required. As used herein, "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust.

Our obligation to pay additional amounts shall not apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner, or a fiduciary, settlor, beneficiary or member of the beneficial owner if the beneficial owner is an estate, trust or partnership, or a person holding a power over an estate or trust administered by a fiduciary holder:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) is or was present or engaged in a trade or business in the United States, has or had a permanent establishment in the United States, or has any other present or former connection with the United States or any political subdivision or taxing authority thereof or therein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) is or was a citizen or resident or is or was treated as a resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) is or was a foreign or domestic personal holding company, a passive foreign investment company or a controlled foreign corporation with respect to the United States or is or was a corporation that has accumulated earnings to avoid United States federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) is or was a bank receiving interest described in Section 881(c)(3)(A) of the Internal Revenue Code of 1986, as amended (the "Code"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) is or was an actual or constructive owner of 10% or more of the total combined voting power of all classes of stock of AT&T entitled to vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) to any holder that is not the sole beneficial owner of the Notes, or a portion thereof, or that is a fiduciary or partnership, but only to the extent that the beneficial owner, a beneficiary or settlor with respect to the fiduciary, or a member of the partnership would not have been entitled to the payment of an additional amount had such beneficial owner, beneficiary, settlor or member received directly its beneficial or distributive share of the payment;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of the Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) to any tax, assessment or governmental charge that is imposed other than by deduction or withholding by AT&T or a paying agent from the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) to any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that is announced or becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar tax, assessment or governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) to any tax, assessment or other governmental charge any paying agent (which term may include us) must withhold from any payment of principal of or interest on any Note, if such payment can be made without such withholding by any other paying agent; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) in the case of any combination of the above items.

In addition, any amounts to be paid on the Notes will be paid net of any deduction or withholding imposed or required pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code, and no additional amounts will be required to be paid on account of any such deduction or withholding.

The Notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable. Except as specifically provided under this heading "- Payment of Additional Amounts" and under the heading "- Redemption Upon a Tax Event," we do not have to make any payment with respect to any tax, assessment or governmental charge imposed by any government or a political subdivision or taxing authority.

Any reference in the terms of the Notes of each series to any amounts in respect of the Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

**Redemption Upon a Tax Event** 

If (a) we become or will become obligated to pay additional amounts with respect to any Notes as described herein under the heading "- Payment of Additional Amounts" as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein), or any change in, or amendments to, any official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective, on or after October 25, 2017 or (b) a taxing authority of the United States takes an action on or after October 25, 2017, whether or not with respect to us or any of our affiliates, that results in a substantial probability that we will or may be required to pay such additional amounts, then we may, at our option, redeem, as a whole, but not in part, the Notes on any interest payment date on not less than 30 nor more than 60 calendar days' prior notice, at a redemption price equal to 100% of their principal amount, together with interest accrued thereon to the date fixed for redemption. No redemption pursuant to (b) above may be made unless we shall have received an opinion of independent counsel to the effect that an act taken by a taxing authority of the United States results in a substantial probability that we will or may be required to pay the additional amounts described herein under the heading "- Payment of Additional Amounts" and we shall have delivered to the trustee a certificate, signed by a duly authorized officer, stating that based on such opinion we are entitled to redeem the Notes pursuant to their terms.

**Further Issues** 

We may from time to time, without notice to or the consent of the holders of the Notes, create and issue further notes ranking equally and ratably with such series in all respects, or in all respects except for the payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date of those further notes. Any further notes will have the same terms as to status, redemption or otherwise as, and will be fungible for United States federal income tax purposes with, the Notes of the applicable series. Any further notes shall be issued pursuant to a resolution of our board of directors, a supplement to the Indenture, or under an officers' certificate pursuant to the Indenture.

**Notices** 

------

Notices to holders of the Notes will be given only to the depositary, in accordance with its applicable policies as in effect from time to time.

**Prescription Period** 

Any money that we deposit with the trustee or any paying agent for the payment of principal or any interest on any global note of any series that remains unclaimed for two years after the date upon which the principal and interest are due and payable will be repaid to us upon our request unless otherwise required by mandatory provisions of any applicable unclaimed property law. After that time, unless otherwise required by mandatory provisions of any unclaimed property law, the holder of the global note will be able to seek any payment to which that holder may be entitled to collect only from us.

**Governing Law** 

The Notes will be governed by and interpreted in accordance with the laws of the State of New York.

**Special Situations Covered by Our Indenture**

***Mergers and Similar Transactions***

We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company. However, we may not take any of these actions unless all the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Where we merge out of existence or sell our assets, the company we merge into or sell to may not be organized under the laws of a foreign country. It must be a corporation organized under the laws of the United States, any State thereof, or the District of Columbia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company we merge into or sell to must agree to be legally responsible for our debt securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merger, sale of assets or other transaction must not cause a default on the securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described below under "- Default and Related Matters - Events of Default - What Is an Event of Default?" A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded.

Further, we may buy substantially all of the assets of another company without complying with any of the foregoing conditions.

***Modification and Waiver of Holders' Contractual Rights***

Under certain circumstances, we can make changes to the Indenture and the securities (including the Notes). Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

*Changes Requiring Approval of Holders.* First, there are changes that cannot be made to the securities without specific approval of holders. The following is a list of those types of changes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the percentage of holders of securities who must consent to a waiver or amendment of the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the rate of interest on any security or change the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the principal due on any security or change the fixed maturity of any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to waive a default in the payment of principal or interest on any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the currency of payment on a security, unless the security provides for payment in a currency that ceases to exist;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of convertible or exchangeable securities, to make changes to conversion or exchange rights that would be adverse to the interests of holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the right of holders to waive an existing default by majority vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the amount of principal or interest payable to holders following a default or change any conversion or exchange rights, or impair the right of holders to sue for payment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change to this list of changes that requires specific approval of holders.

*Changes Requiring a Majority Vote.* The second type of change to the Indenture and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except as set forth in the following paragraph. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain each holder's individual consent to the waiver.

*Changes Not Requiring Approval of Holders.* The third type of change does not require any vote by holders of securities. This type includes, among others, clarifications of ambiguous contract terms, changes to make securities payable in U.S. dollars (if the stated denomination ceases to exist) and other changes that would not materially adversely affect holders of the securities.

*Further Details Concerning Voting.* When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent determined on the date of original issuance of these securities.

Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for the applicable holders money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the Indenture. However, the Indenture does not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

***Holders who hold in "street name" and other indirect holders, including holders of any securities issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the Indenture or the securities or request a waiver.***

**Discharge of Our Obligations**

We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for the applicable holders with the trustee and certain other conditions are met. The deposit must be held in trust for the benefit of all direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities.

If we accomplish full discharge, as described above, holders will have to rely solely on the trust deposit for repayment of the securities. Holders could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the trustee and holders against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations.

**Liens on Assets**

The Indenture does not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

**Default and Related Matters**

***Ranking Compared to Other Creditors***

The securities are not secured by any of our property or assets. Accordingly, ownership of securities means each holder is one of our unsecured creditors. The securities are not subordinated to any of our other debt obligations

------

and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee has a right to receive payment for its administrative services prior to any payment to security holders after a default.

***Events of Default***

Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

*What Is an Event of Default?* The term "event of default" with respect to any series of securities means any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any interest payment on the securities of such series when it is due, and we do not cure this default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any payment of principal when it is due at the maturity of such series of securities or upon redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to comply with any of our other agreements regarding a particular series of securities or with a supplemental indenture, and after we have been notified of the default by the trustee or holders of 25% in principal amount of the series, we do not cure the default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We file for bankruptcy, or other events in bankruptcy, insolvency or reorganization occur.

***Remedies if an Event of Default Occurs***

Holders and the trustee will have the following remedies if an event of default occurs:

*Acceleration.* If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived.

*Special Duties of Trustee.* If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the Indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

*Other Remedies of Trustee.* If an event of default occurs, the trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the Indenture, including bringing a lawsuit.

*Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests*. The trustee is not required to take any action under the Indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an "indemnity". If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the Indenture.

*Individual Actions Holders May Take if the Trustee Fails to Act.* Before a holder bypasses the trustee and brings such holder's own lawsuit or other formal legal action or take other steps to enforce such holder's rights or protect such holder's interests relating to the securities, the following must occur:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such holder must give the trustee written notice that an event of default has occurred and remains uncured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The holders of 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer indemnity reasonably satisfactory to the trustee against the cost and other liabilities of taking that action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the 60-day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with the request.

------

However, a holder is entitled at any time to bring an individual lawsuit for the payment of the money due on such holder's security on or after its due date.

***Waiver of Default***

The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on a holder's debt security, however, without such holder's individual approval.

***We Will Give the Trustee Information About Defaults Annually***

Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the Indenture and all the securities under it, or else specifying any default.

The trustee may withhold from holders notice of any uncured default, except for payment defaults, if it determines that withholding notice is in holders' interest.

***Holders who hold in "street name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to make or cancel a declaration of acceleration.***

**Regarding the Trustee** 

The Bank of New York Mellon Trust Company, N.A. is the trustee under the Indenture. In addition, affiliates of The Bank of New York Mellon Trust Company, N.A. may perform various commercial banking and investment banking services for us and our subsidiaries from time to time in the ordinary course of business.

**DESCRIPTION OF THE 7.000% GLOBAL NOTES DUE 2040 AND THE 4.875% GLOBAL NOTES DUE 2044**

*The following summary of AT&T's above referenced debt securities is based on and qualified by the indenture, dated as of November 1, 1994, with The Bank of New York Mellon, acting as trustee (the "Indenture") and the 7.000% Global Notes due 2040 (the "2040 Notes") and the 4.875% Global Notes due 2044 (the "2044 Notes" and, together with the 2040 Notes, the "Notes"). For a complete description of the terms and provisions of the Notes, please refer to the Indenture, which is filed as an exhibit to AT&T's Annual Report on Form 10-K for the year ended December 31, 2025 and to the forms of Notes, which are filed as exhibits to the Form 8-As filed with the Securities and Exchange Commission on May 1, 2009 and May 30, 2012.*

**General** 

The 2040 Notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• were issued in an aggregate initial principal amount of £1,100,000,000, which remains the amount outstanding, subject to our ability to issue additional 2040 Notes which may be of the same series as the 2040 Notes as described under "- Further Issues";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mature on April 30, 2040;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• bear interest at the rate of 7.000% per annum, payable annually in arrears;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are repayable at par at maturity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are redeemable by us at the time described below under "- Optional Redemption" and in connection with certain tax events as described below under "- Redemption Upon a Tax Event"; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are not subject to any sinking fund.

The 2044 Notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• were issued in an aggregate initial principal amount of £1,250,000,000, which remains the amount outstanding, subject to our ability to issue additional 2044 Notes which may be of the same series as the 2044 Notes as described under "- Further Issues";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mature on June 1, 2044;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• bear interest at the rate of 4.875% per annum, payable annually in arrears;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are repayable at par at maturity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are redeemable by us at the time described below under "- Optional Redemption" and in connection with certain tax events as described below under "- Redemption Upon a Tax Event"; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are not subject to any sinking fund.

The Notes are unsecured and unsubordinated obligations and rank *pari passu* with all other indebtedness issued under our Indenture. Each series of Notes constitutes a separate series under the Indenture. The Notes are issued in fully registered form only and (i) with respect to the 2040 Notes, in minimum denominations of £50,000 and integral multiples of £50,000 thereafter and (ii) with respect to the 2044 Notes, in minimum denominations of £100,000 and integral multiples of £1,000 in excess thereof. Principal and interest payments of the Notes are payable by us in pound sterling. Payments of principal, interest and additional amounts, if any, in respect of the Notes will be made to the Depository Trust Company, Euroclear System, Clearstream Banking S.A. or such nominee or common depositary, as the case may be, as registered holder thereof.

For purposes of the 2040 Notes, a business day means any day other than a Saturday or Sunday or a day on which banking institutions in the City of New York or the City of London are authorized or required by law or executive order to close.

For purposes of the 2044 Notes, a business day means a business day in the City of New York and London.

**Interest**

The 2040 Notes bear interest at the rate of 7.000% per annum and the 2044 Notes bear interest at the rate of 4.875% per annum.

We pay interest on the 2040 Notes annually in arrears on April 30, commencing on April 30, 2010, to the persons in whose names our 2040 Notes are registered at the close of business on the April 15 preceding each interest payment date. We pay interest on the 2044 Notes annually in arrears on June 1, commencing on June 1, 2013, to the persons in whose names the 2044 Notes are registered at the close of business on the May 15 preceding the interest payment date.

The 2040 Notes mature on April 30, 2040 and the 2044 Notes will mature on June 1, 2044.

Interest on the Notes is computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes, to but excluding the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

**Optional Redemption of the Notes** 

The Notes of each series will be redeemable, as a whole or in part, at our option, at any time and from time to time on at least 30 days', but not more than 60 days', prior notice mailed to the registered address of each holder of the Notes of that series. The redemption price will be equal to the greater of (1) 100% of the principal amount of the Notes of that series to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) discounted to the redemption date, on an annual basis (actual/actual (ICMA)), at a rate equal to the Treasury Rate (as defined below) and 25 basis points for each series of the Notes. In either case, accrued interest will be payable to the redemption date.

"*Treasury Rate*" means the price, expressed as a percentage (rounded to three decimal places, 0.0005 being rounded upwards), at which the gross redemption yield (as calculated by the trustee) on the Notes of the applicable series, if they were to be purchased at such price on the third dealing day prior to the date fixed for redemption, would be equal to the gross redemption yield on such dealing day of the Reference Bond (as defined below) on the basis of the middle market price of the Reference Bond prevailing at 11:00 a.m. (London time) on such dealing day as determined by the trustee.

"*Reference Bond*" means, in relation to any Treasury Rate calculation, at the discretion of the trustee, a United Kingdom government bond whose maturity is closest to the maturity of the Notes of the applicable series, or if the trustee in its discretion considers that such similar bond is not in issue, such other United Kingdom government bond as the trustee may, with the advice of three brokers of, and/or market makers in, United Kingdom government bonds selected by the trustee, determine to be appropriate for determining the Treasury Rate.

"*Remaining Scheduled Payments*" means, with respect to each Note of a series to be redeemed, the remaining scheduled payments of principal of and interest on the Note that would be due after the related

------

redemption date but for the redemption. If that redemption date is not an interest payment date with respect to the applicable series of Notes, the amount of the next succeeding scheduled interest payment on the Notes will be reduced by the amount of interest accrued on the Notes to the redemption date.

On and after the redemption date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with a paying agent or the trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date.

In the case of any partial redemption, selection of the Notes of a series will be made by the trustee by lot or by such other method as the trustee in its sole discretion deems to be fair and appropriate.

**Redemption for Taxation Reasons** 

If (a) as a result of any change in, or amendment to, the laws or regulations of a Relevant Jurisdiction (as defined below under "Interpretation"), or any change in the official interpretation of the laws or regulations of a Relevant Jurisdiction, which change or amendment becomes effective after April 24, 2009 with respect to the 2040 Notes and May 22, 2012 with respect to the 2044 Notes, on the next Interest Payment Date we would be required to pay additional amounts as provided or referred to below under "- Payment Without Withholding" and (b) the requirement cannot be avoided by our taking reasonable measures available to us, we may at our option, having given not less than 30 nor more than 60 days' notice to the holders of Notes of each applicable series (which notice shall be irrevocable), redeem all, but not a portion of, the applicable series of Notes at any time at their principal amount together with interest accrued to, but excluding, the date of redemption provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which we would be obliged to pay such additional amounts were a payment in respect of the applicable series of Notes then due. Prior to the publication of any notice of redemption pursuant to this paragraph, we shall deliver to the trustee a certificate signed by two of our executive officers stating that the requirement referred to in (a) above will apply on the next Interest Payment Date and setting forth a statement of facts showing that the conditions precedent to the right of AT&T so to redeem have occurred, cannot be avoided by us taking reasonable measures available to us and an opinion of independent legal advisers of recognized international standing to the effect that AT&T has or will become obliged to pay such additional amounts as a result of the change or amendment, in each case to be held by the trustee and made available for viewing at the offices of the trustee on request by any holder of each applicable series of Notes.

**Payment Without Withholding** 

All payments in respect of the Notes by or on behalf of AT&T shall be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature ("Taxes") imposed, collected, withheld, assessed or levied by or on behalf of the Relevant Jurisdiction, unless the withholding or deduction of the Taxes is required by law. In that event, we will pay such additional amounts to a holder who is a United States Alien (as defined below) as may be necessary in order that the net amounts received by the holder after the withholding or deduction shall equal the respective amounts which would have been receivable in respect of each applicable series of the Notes in the absence of the withholding or deduction; except that no such additional amounts shall be payable in relation to any payment in respect of any Note:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) where such withholding or deduction would not have been so imposed but for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in the case of payment by AT&T, the existence of any present or former connection between the holder of the Note (or between a fiduciary, settlor, shareholder, beneficiary or member of the holder of the Note, if such holder is an estate, a trust, a corporation or a partnership) and the United States, including, without limitation, such holder (or such fiduciary, settlor, shareholder, beneficiary or member) being or having been a citizen or resident or treated as a resident thereof, or being or having been engaged in trade or business or presence therein, or having or having had a permanent establishment therein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) in the case of payment by AT&T, the present or former status of the holder of the Note as a personal holding company, a foreign personal holding company, a passive foreign investment company, or a controlled foreign corporation for United States federal income tax purposes or a corporation which accumulates earnings to avoid United States federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) in the case of payment by AT&T, the past or present or future status of the holder of the Note as the actual or constructive owner of 10% or more of either the total combined voting power of all classes of stock of AT&T entitled to vote if AT&T was treated as a corporation, or the capital or profits interest in AT&T, if AT&T is

------

treated as a partnership for United States federal income tax purposes or as a bank receiving interest described in Section 881(c) (3) (A) of the Internal Revenue Code of 1986, as amended; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the failure by the holder of the Note to comply with any certification, identification or other reporting requirements concerning the nationality, residence, identity or connection with the United States (in the case of payment by AT&T) of such holder, if compliance is required by statute or by regulation as a precondition to exemption from such withholding or deduction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) in the case of payment by AT&T to any United States Alien, if such person is a fiduciary or partnership or other than the sole beneficial owner of any such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such partnership or the beneficial owner would not have been entitled to the additional amounts had such beneficiary, settlor, member or beneficial owner been the bearer of such Note. As used herein, "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) to the extent that the withholding or deduction is as a result of the imposition of any gift, inheritance, estate, sales, transfer, personal property or any similar tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) to, or to a third party on behalf of, a holder who is liable for the Taxes in respect of the Notes by reason of his having any or some present or former connection, including but not limited to fiscal residency, fiscal deemed residency and substantial interest shareholdings, with the Relevant Jurisdiction, other than the mere holding of the Notes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) presented for payment more than 30 days after the Relevant Date except to the extent that a holder would have been entitled to additional amounts on presenting the relevant Notes for payment on the last day of the period of 30 days assuming that day to have been an Interest Payment Date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) any tax, assessment or other governmental charge required to be withheld by any paying agent from any payment of principal or of interest on any Notes, if such payment can be made without withholding by any other paying agent;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of our Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) any combination of (a), (b), (c), (d), (e), (f), (g) or (h).

**Interpretation** 

As used in this description:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) "Relevant Date" means the date on which the payment first becomes due but, if the full amount of the money payable has not been received by the trustee on or before the due date, it means the date which is seven days after the date on which, the full amount of the money having been so received, notice to that effect shall have been duly given to the holders of Notes by us; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) "Relevant Jurisdiction" means the State of Delaware and the United States or any political subdivision or any authority thereof or therein having power to tax or any other jurisdiction or any political subdivision or any authority thereof or therein having power to tax to which we become subject in respect of payments made by it of principal and interest on the Notes.

**Additional Amounts** 

Any reference in the terms of the Notes to any amounts in respect of the Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

**Further Issues** 

We may from time to time, without notice to or the consent of the holders of any series of the Notes, create and issue further notes ranking equally and ratably with such series in all respects, or in all respects except for the payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date

------

of those further notes. Any further notes will have the same terms as to status, redemption or otherwise as the Notes of the applicable series. Any further notes shall be issued pursuant to a resolution of our board of directors, a supplement to the Indenture, or under an officers' certificate pursuant to the Indenture.

**Governing Law** 

The Notes will be governed by and interpreted in accordance with the laws of the State of New York.

**Special Situations Covered by Our Indenture**

***Mergers and Similar Transactions***

We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company, or to buy substantially all of the assets of another company. However, we may not take any of these actions unless all the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Where we merge out of existence or sell our assets, the company we merge into or sell to may not be organized under the laws of a foreign country. It must be a corporation organized under the laws of the United States, any State thereof, or the District of Columbia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company we merge into or sell to must agree to be legally responsible for our debt securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merger, sale of assets or other transaction must not cause a default on the securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described below under "- Default and Related Matters - Events of Default - What Is an Event of Default?" A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded.

***Modification and Waiver of Holders' Contractual Rights***

Under certain circumstances, we can make changes to the Indenture and the securities (including the Notes). Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

*Changes Requiring Approval of Holders.* First, there are changes that cannot be made to the securities without specific approval of holders. The following is a list of those types of changes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the percentage of holders of securities who must consent to a waiver or amendment of the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the rate of interest on any security or change the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the principal due on any security or change the fixed maturity of any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to waive a default in the payment of principal or interest on any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the currency of payment on a security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of convertible or exchangeable securities, to make changes to conversion or exchange rights that would be adverse to the interests of holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the right of holders to waive an existing default by majority vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the amount of principal or interest payable to holders following a default or change any conversion or exchange rights, or impair the right of holders to sue for payment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change to this list of changes that requires specific approval of holders.

*Changes Requiring a Majority Vote.* The second type of change to the Indenture and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except for clarifying changes and certain other changes that would not adversely affect holders of the securities. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain each holder's individual consent to the waiver.

------

*Changes Not Requiring Approval of Holders.* The third type of change does not require any vote by holders of securities. This type includes, among others, clarifications of ambiguous contract terms and other changes that would not materially adversely affect holders of the securities.

*Further Details Concerning Voting.* When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent determined on the date of original issuance of these securities.

Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for the applicable holders money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the Indenture. However, the Indenture does not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

***Holders who hold in "street name" and other indirect holders, including holders of any securities issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the Indenture or the securities or request a waiver.***

**Discharge of Our Obligations**

We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for the applicable holders with the trustee and certain other conditions are met. The deposit must be held in trust for the benefit of all direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities.

If we accomplish full discharge, as described above, holders will have to rely solely on the trust deposit for repayment of the securities. Holders could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the trustee and holders against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations.

**Liens on Assets**

The Indenture does not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

**Default and Related Matters**

***Ranking Compared to Other Creditors***

The securities are not secured by any of our property or assets. Accordingly, ownership of securities means each holder is one of our unsecured creditors. The securities are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee has a right to receive payment for its administrative services prior to any payment to security holders after a default.

***Events of Default***

Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

*What Is an Event of Default?* The term "event of default" with respect to any series of securities means any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any interest payment on the securities of such series when it is due, and we do not cure this default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any payment of principal when it is due at the maturity of such series of securities or upon redemption.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to comply with any of our other agreements regarding a particular series of securities or with a supplemental indenture, and after we have been notified of the default by the trustee or holders of 25% in principal amount of the series, we do not cure the default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We file for bankruptcy, or other events in bankruptcy, insolvency or reorganization occur.

***Remedies if an Event of Default Occurs***

Holders and the trustee will have the following remedies if an event of default occurs:

*Acceleration.* If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived.

*Special Duties of Trustee.* If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the Indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

*Other Remedies of Trustee.* If an event of default occurs, the trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the Indenture, including bringing a lawsuit.

*Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests*. The trustee is not required to take any action under the Indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an "indemnity". If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the Indenture.

*Individual Actions Holders May Take if the Trustee Fails to Act.* Before a holder bypasses the trustee and bring such holder's own lawsuit or other formal legal action or take other steps to enforce such holder's rights or protect such holder's interests relating to the securities, the following must occur:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such holder must give the trustee written notice that an event of default has occurred and remains uncured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The holders of 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer indemnity reasonably satisfactory to the trustee against the cost and other liabilities of taking that action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the 60-day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with the request.

However, a holder is entitled at any time to bring an individual lawsuit for the payment of the money due on such holder's security on or after its due date.

***Waiver of Default***

The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on a holder's debt security, however, without such holder's individual approval.

***We Will Give the Trustee Information About Defaults Annually***

Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the Indenture and all the securities under it, or else specifying any default.

The trustee may withhold from holders notice of any uncured default, except for payment defaults, if it determines that withholding notice is in holders' interest.

------

**Holders who hold in "street name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to make or cancel a declaration of acceleration.**

**Regarding the Trustee**

The Bank of New York Mellon is the trustee under the Indenture. In addition, affiliates of The Bank of New York Mellon may perform various commercial banking and investment banking services for us and our subsidiaries from time to time in the ordinary course of business.

**DESCRIPTION OF THE 4.250% GLOBAL NOTES DUE 2043**

*The following summary of AT&T's above referenced debt securities is based on and qualified by the indenture, dated as of May 15, 2013, with The Bank of New York Mellon Trust Company, N.A., acting as trustee (the "Indenture") and the 4.250% Global Notes due 2043 (the "Notes"). For a complete description of the terms and provisions of the Notes, please refer to the Indenture, which is filed as an exhibit to AT&T's Annual Report on Form 10-K for the year ended December 31, 2025 and to the form of Notes, which is filed as an exhibit to the Form 8-A filed with the Securities and Exchange Commission on May 15, 2013.*

**General**

The Notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• were issued in an aggregate initial principal amount of £1,000,000,000, which remains the amount outstanding, subject to our ability to issue additional Notes which may be of the same series as the Notes as described under "- Further Issues";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mature on June 1, 2043;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• bear interest at the rate of 4.250% per annum, payable annually in arrears;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are repayable at par at maturity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are redeemable by us at the time described below under "- Optional Redemption" and in connection with certain tax events as described below under "- Redemption Upon a Tax Event"; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are not subject to any sinking fund.

The Notes are unsecured and unsubordinated obligations and rank *pari passu* with all other indebtedness issued under our Indenture. The Notes constitute a single series under the Indenture. The Notes are issued in fully registered form only and in minimum denominations of £100,000 and integral multiples of £1,000 in excess thereof. Principal and interest payments on the Notes are payable by us in pound sterling. Payments of principal, interest and additional amounts, if any, in respect of the Notes will be made to Euroclear System, Clearstream Banking S.A. or such nominee or common depositary, as the case may be, as registered holder thereof. Under the terms of the Indenture, if the pound sterling ceases to exist when payments on the Notes are due under any circumstances, AT&T may supplement the Indenture to allow for payment in U.S. dollars. The principal and interest payable in U.S. dollars on a Note at maturity, or upon redemption, will be paid by wire transfer of immediately available funds against presentation of a Note at the office of the paying agent.

For purposes of the Notes, a business day means a business day in the City of New York and London.

**Interest**

The Notes bear interest at the rate of 4.250% per annum.

We pay interest on the Notes annually in arrears on June 1, commencing on June 1, 2014, to the persons in whose names the Notes are registered at the close of business on the May 15 preceding the interest payment date.

The Notes will mature on June 1, 2043.

Interest on the Notes is computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes, to but excluding the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

**Optional Redemption** 

------

At any time prior to December 1, 2042, the Notes will be redeemable, as a whole or in part, at our option, at any time and from time to time on at least 30 days', but not more than 60 days', prior notice mailed to the registered address of each holder of the Notes. The redemption price will be equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) discounted to the redemption date, on an annual basis (ACTUAL/ACTUAL (ICMA)), at a rate equal to the Treasury Rate (as defined below) and 20 basis points for the Notes. In either case, accrued interest will be payable to the redemption date. At any time on or after December 1, 2042, we have the option to redeem the Notes, as a whole or in part, on at least 30 days', but not more than 60 days', prior notice mailed to the registered address of each holder of the Notes at a redemption price equal to 100% of the principal amount of the Notes to be redeemed. Accrued interest will be payable to the redemption date.

"*Treasury Rate*" means the price, expressed as a percentage (rounded to three decimal places, 0.0005 being rounded upwards), at which the gross redemption yield on the Notes, if they were to be purchased at such price on the third dealing day prior to the date fixed for redemption, would be equal to the gross redemption yield on such dealing day of the Reference Bond (as defined below) on the basis of the middle market price of the Reference Bond prevailing at 11:00 a.m. (London time) on such dealing day as determined by the Company or an investment bank appointed by the Company.

"*Reference Bond*" means, in relation to any Treasury Rate calculation, a United Kingdom government bond whose maturity is closest to the maturity of the Notes, or if the Company or an investment bank appointed by the Company considers that such similar bond is not in issue, such other United Kingdom government bond as the Company or an investment bank appointed by the Company, with the advice of three brokers of, and/or market makers in, United Kingdom government bonds selected by the Company or an investment bank appointed by the Company, determine to be appropriate for determining such Treasury Rate.

"*Remaining Scheduled Payments*" means, with respect to each Note to be redeemed, the remaining scheduled payments of principal of and interest on the Note that would be due after the related redemption date but for the redemption. If that redemption date is not an interest payment date with respect to a Note, the amount of the next succeeding scheduled interest payment on the Note will be reduced by the amount of interest accrued on the Note to the redemption date.

On and after the redemption date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with a paying agent or the trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date.

In the case of any partial redemption, selection of the Notes will be made by the trustee by lot or by such other method as the trustee in its sole discretion deems to be fair and appropriate.

**Redemption for Taxation Reasons**

If (a) as a result of any change in, or amendment to, the laws or regulations of a Relevant Jurisdiction (as defined below under "Interpretation"), or any change in the official interpretation of the laws or regulations of a Relevant Jurisdiction, which change or amendment becomes effective after May 8, 2013, on the next Interest Payment Date we would be required to pay additional amounts as provided or referred to below under "- Payment Without Withholding" and (b) the requirement cannot be avoided by our taking reasonable measures available to us, we may at our option, having given not less than 30 nor more than 60 days' notice to the holders of Notes (which notice shall be irrevocable), redeem all, but not a portion of, the Notes at any time at their principal amount together with interest accrued to, but excluding, the date of redemption provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which we would be obliged to pay such additional amounts were a payment in respect of the Notes then due. Prior to the publication of any notice of redemption pursuant to this paragraph, we shall deliver to the trustee a certificate signed by two of our executive officers stating that the requirement referred to in (a) above will apply on the next Interest Payment Date and setting forth a statement of facts showing that the conditions precedent to the right of AT&T so to redeem have occurred, cannot be avoided by us taking reasonable measures available to us and an opinion of independent legal advisers of recognized international standing to the effect that AT&T has or will become obliged to pay such additional amounts as a result of the change or amendment, in each case to be held by the trustee and made available for viewing at the offices of the trustee on request by any holder of the Notes.

**Payment Without Withholding** 

------

All payments in respect of the Notes by or on behalf of AT&T shall be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature ("Taxes") imposed, collected, withheld, assessed or levied by or on behalf of the Relevant Jurisdiction, unless the withholding or deduction of the Taxes is required by law. In that event, we will pay such additional amounts to a holder who is a United States Alien (as defined below) as may be necessary in order that the net amounts received by the holder after the withholding or deduction shall equal the respective amounts which would have been receivable in respect of the Notes in the absence of the withholding or deduction; except that no such additional amounts shall be payable in relation to any payment in respect of any Note:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) where such withholding or deduction would not have been so imposed but for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in the case of payment by AT&T, the existence of any present or former connection between the holder of the Note (or between a fiduciary, settlor, shareholder, beneficiary or member of the holder of the Note, if such holder is an estate, a trust, a corporation or a partnership) and the United States, including, without limitation, such holder (or such fiduciary, settlor, shareholder, beneficiary or member) being or having been a citizen or resident or treated as a resident thereof, or being or having been engaged in trade or business or presence therein, or having or having had a permanent establishment therein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) in the case of payment by AT&T, the present or former status of the holder of the Note as a personal holding company, a foreign personal holding company, a passive foreign investment company, or a controlled foreign corporation for United States federal income tax purposes or a corporation which accumulates earnings to avoid United States federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) in the case of payment by AT&T, the past or present or future status of the holder of the Note as the actual or constructive owner of 10% or more of either the total combined voting power of all classes of stock of AT&T entitled to vote if AT&T was treated as a corporation, or the capital or profits interest in AT&T, if AT&T is treated as a partnership for United States federal income tax purposes or as a bank receiving interest described in Section 881(c)(3)(A) of the Internal Revenue Code of 1986, as amended; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the failure by the holder of the Note to comply with any certification, identification or other reporting requirements concerning the nationality, residence, identity or connection with the United States (in the case of payment by AT&T) of such holder, if compliance is required by statute or by regulation as a precondition to exemption from such withholding or deduction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) in the case of payment by AT&T to any United States Alien, if such person is a fiduciary or partnership or other than the sole beneficial owner of any such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such partnership or the beneficial owner would not have been entitled to the additional amounts had such beneficiary, settlor, member or beneficial owner been the bearer of such Note. As used herein, "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) to the extent that the withholding or deduction is as a result of the imposition of any gift, inheritance, estate, sales, transfer, personal property or any similar tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) to, or to a third party on behalf of, a holder who is liable for the Taxes in respect of the Notes by reason of his having any or some present or former connection, including but not limited to fiscal residency, fiscal deemed residency and substantial interest shareholdings, with the Relevant Jurisdiction, other than the mere holding of the Notes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) presented for payment more than 30 days after the Relevant Date except to the extent that a holder would have been entitled to additional amounts on presenting the relevant Notes for payment on the last day of the period of 30 days assuming that day to have been an Interest Payment Date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) any tax, assessment or other governmental charge required to be withheld by any paying agent from any payment of principal or of interest on any Notes, if such payment can be made without withholding by any other paying agent;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of our Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) any combination of (a), (b), (c), (d), (e), (f), (g) or (h).

***Interpretation***

As used in this description:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) "Relevant Date" means the date on which the payment first becomes due but, if the full amount of the money payable has not been received by the trustee on or before the due date, it means the date which is seven days after the date on which, the full amount of the money having been so received, notice to that effect shall have been duly given to the holders of Notes by us; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) "Relevant Jurisdiction" means the State of Delaware and the United States or any political subdivision or any authority thereof or therein having power to tax or any other jurisdiction or any political subdivision or any authority thereof or therein having power to tax to which we become subject in respect of payments made by it of principal and interest on the Notes.

***Additional Amounts***

Any reference in the terms of the Notes to any amounts in respect of the Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

**Further Issues** 

We may from time to time, without notice to or the consent of the holders of the Notes, create and issue further notes ranking equally and ratably with such Notes in all respects, or in all respects except for the payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date of those further notes. Any further notes will have the same terms as to status, redemption or otherwise as the Notes. Any further notes shall be issued pursuant to a resolution of our board of directors, a supplement to the Indenture, or under an officers' certificate pursuant to the Indenture.

**Governing Law**

The Notes will be governed by and interpreted in accordance with the laws of the State of New York.

**Special Situations Covered by Our Indenture**

***Mergers and Similar Transactions***

We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company. However, we may not take any of these actions unless all the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Where we merge out of existence or sell our assets, the company we merge into or sell to may not be organized under the laws of a foreign country. It must be a corporation organized under the laws of the United States, any State thereof, or the District of Columbia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company we merge into or sell to must agree to be legally responsible for our debt securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merger, sale of assets or other transaction must not cause a default on the securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described below under "- Default and Related Matters - Events of Default - What Is an Event of Default?" A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded.

Further, we may buy substantially all of the assets of another company without complying with any of the foregoing conditions.

***Modification and Waiver of Holders' Contractual Rights***

Under certain circumstances, we can make changes to the Indenture and the securities (including the Notes). Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

------

*Changes Requiring Approval of Holders.* First, there are changes that cannot be made to the securities without specific approval of holders. The following is a list of those types of changes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the percentage of holders of securities who must consent to a waiver or amendment of the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the rate of interest on any security or change the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the principal due on any security or change the fixed maturity of any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to waive a default in the payment of principal or interest on any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the currency of payment on a security, unless the security provides for payment in a currency that ceases to exist;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of convertible or exchangeable securities, to make changes to conversion or exchange rights that would be adverse to the interests of holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the right of holders to waive an existing default by majority vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the amount of principal or interest payable to holders following a default or change any conversion or exchange rights, or impair the right of holders to sue for payment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change to this list of changes that requires specific approval of holders.

*Changes Requiring a Majority Vote.* The second type of change to the Indenture and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except as set forth in the following paragraph. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain each holder's individual consent to the waiver.

*Changes Not Requiring Approval of Holders.* The third type of change does not require any vote by holders of securities. This type includes, among others, clarifications of ambiguous contract terms, changes to make securities payable in U.S. dollars (if the stated denomination ceases to exist) and other changes that would not materially adversely affect holders of the securities.

*Further Details Concerning Voting.* When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent determined on the date of original issuance of these securities.

Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for the applicable holders money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the Indenture. However, the Indenture does not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

***Holders who hold in "street name" and other indirect holders, including holders of any securities issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the Indenture or the securities or request a waiver.***

**Discharge of Our Obligations**

We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for the applicable holders with the trustee and certain other conditions are met. The deposit must be held in trust for the benefit of all direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities.

------

If we accomplish full discharge, as described above, holders will have to rely solely on the trust deposit for repayment of the securities. Holders could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the trustee and holders against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations.

**Liens on Assets**

The Indenture does not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

**Default and Related Matters**

***Ranking Compared to Other Creditors***

The securities are not secured by any of our property or assets. Accordingly, ownership of securities means each holder is one of our unsecured creditors. The securities are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee has a right to receive payment for its administrative services prior to any payment to security holders after a default.

***Events of Default***

Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

*What Is an Event of Default?* The term "event of default" with respect to any series of securities means any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any interest payment on the securities of such series when it is due, and we do not cure this default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any payment of principal when it is due at the maturity of such series of securities or upon redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to comply with any of our other agreements regarding a particular series of securities or with a supplemental indenture, and after we have been notified of the default by the trustee or holders of 25% in principal amount of the series, we do not cure the default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We file for bankruptcy, or other events in bankruptcy, insolvency or reorganization occur.

***Remedies if an Event of Default Occurs***

Holders and the trustee will have the following remedies if an event of default occurs:

*Acceleration.* If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived.

*Special Duties of Trustee.* If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the Indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

*Other Remedies of Trustee.* If an event of default occurs, the trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the Indenture, including bringing a lawsuit.

*Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests*. The trustee is not required to take any action under the Indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an "indemnity". If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the Indenture.

------

*Individual Actions Holders May Take if the Trustee Fails to Act.* Before a holder bypasses the trustee and brings such holder's own lawsuit or other formal legal action or take other steps to enforce such holder's rights or protect such holder's interests relating to the securities, the following must occur:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such holder must give the trustee written notice that an event of default has occurred and remains uncured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The holders of 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer indemnity reasonably satisfactory to the trustee against the cost and other liabilities of taking that action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the 60-day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with the request.

However, a holder is entitled at any time to bring an individual lawsuit for the payment of the money due on such holder's security on or after its due date.

***Waiver of Default***

The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on a holder's debt security, however, without such holder's individual approval.

***We Will Give the Trustee Information About Defaults Annually***

Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the Indenture and all the securities under it, or else specifying any default.

The trustee may withhold from holders notice of any uncured default, except for payment defaults, if it determines that withholding notice is in holders' interest.

**Holders who hold in "street name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to make or cancel a declaration of acceleration.**

**Regarding the Trustee**

The Bank of New York Mellon Trust Company, N.A. is the trustee under the Indenture. In addition, affiliates of The Bank of New York Mellon Trust Company, N.A. may perform various commercial banking and investment banking services for us and our subsidiaries from time to time in the ordinary course of business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mature on December 4, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• bear interest at the rate of 2.900% per annum, payable annually in arrears;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• were issued in an aggregate initial principal amount of £745,000,000, which remains the amount outstanding, subject to our ability to issue additional 4.375% 2029 Notes which may be of the same series as the 4.375% 2029 Notes as described under "- Further Issues";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mature on September 14, 2029;

The 2033 Notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• were issued in an aggregate initial principal amount of £342,361,000, which remains the amount outstanding, subject to our ability to issue additional 2033 Notes which may be of the same series as the 2033 Notes as described under "- Further Issues";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mature on November 18, 2033;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• bear interest at the rate of 5.200% per annum, payable annually in arrears;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are not subject to any sinking fund.

The Notes are unsecured and unsubordinated obligations and rank *pari passu* with all other indebtedness issued under our Indenture. Each series of Notes constitutes a separate series under the Indenture. The Notes are issued in fully registered form only and in minimum denominations of £100,000 and integral multiples of £1,000 in excess thereof. Principal and interest payments on the Notes are payable by us in pound sterling. Payments of principal, interest and additional amounts, if any, in respect of the Notes will be made to Euroclear System, Clearstream Banking S.A. or such nominee or common depositary, as the case may be, as registered holder thereof. Under the terms of the Indenture, if the pound sterling ceases to exist when payments on the Notes are due under any circumstances, AT&T may supplement the Indenture to allow for payment in U.S. dollars. The principal and interest payable in U.S. dollars on a Note at maturity, or upon redemption, will be paid by wire transfer of immediately available funds against presentation of a Note at the office of the paying agent.

For purposes of the 2.900% 2026 Notes, a business day means a business day in the City of New York or the City of London.

For purposes of the 4.375% 2029 Notes and 2033 Notes, a business day means any day other than a Saturday or Sunday and that, in the City of New York or London, is not a day on which banking institutions are generally authorized or obligated by law to close, and is a day on which the Trans-European Automated Real-time Gross Settlement Express Transfer (TARGET) System, or any successor thereto, operates.

------

**Interest**

The 2.900% 2026 Notes bear interest at the rate of 2.900% per annum, the 4.375% 2029 Notes bear interest at the rate of 4.375% per annum and the 2033 Notes bear interest at the rate of 5.200% per annum.

We pay interest on the 2.900% 2026 Notes annually in arrears on each December 4, commencing on December 4, 2018, to the persons in whose names the 2.900% 2026 Notes are registered at the close of business on the business day preceding the interest payment date. We pay interest on the 4.375% 2029 Notes annually in arrears on September 14, commencing on September 14, 2016, to the persons in whose names the 4.375% 2029 Notes are registered at the close of business on the business day preceding the interest payment date. We pay interest on the 2033 Notes annually in arrears on November 18, commencing on November 18, 2016, to the persons in whose names our 2033 Notes are registered at the close of business on the business day preceding the interest payment date.

The 2.900% 2026 Notes will mature on December 4, 2026, the 4.375% 2029 Notes will mature on September 14, 2029 and the 2033 Notes will mature on November 18, 2033.

Interest on the Notes is computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes, to but excluding the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

**Optional Redemption**

At any time prior to September 4, 2026, the 2.900% 2026 Notes may be redeemed, as a whole or in part, at our option, at any time and from time to time on at least 30 days', but not more than 60 days', prior notice sent to the registered address of each holder of the Notes to be redeemed. The redemption price will be calculated by us and will be equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) discounted to the redemption date, on an annual basis (ACTUAL/ACTUAL (ICMA)), at a rate equal to the Treasury Rate (as defined below) plus 25 basis points. In either case, accrued but unpaid interest will be payable to the redemption date. At any time on or after September 4, 2026, the Notes may be redeemed, as a whole or in part, at our option, at any time and from time to time on at least 30 days', but not more than 60 days', prior notice sent to the registered address of each holder of the Notes, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed. Accrued but unpaid interest will be payable to the redemption date.

The 4.375% 2029 Notes and the 2033 Notes may be redeemed as a whole or in part, at our option, at any time and from time to time on at least 30 days', but not more than 60 days', prior notice mailed to the registered address of each holder of the applicable series of Notes. The redemption price will be equal to the greater of (1) 100% of the principal amount of the applicable series of Notes to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) discounted to the redemption date, on an annual basis (ACTUAL/ACTUAL (ICMA)), at a rate equal to the Treasury Rate (as defined below) plus, for the 4.375% 2029 Notes, 35 basis points, and for the 2033 Notes, 25 basis points. In either case, accrued but unpaid interest will be payable to the redemption date. We will calculate the redemption price in connection with any redemption hereunder.

"*Treasury Rate*" means the price, expressed as a percentage (and, with respect to the 4.375% 2029 Notes and the 2033 Notes, rounded to three decimal places, 0.0005 being rounded upwards), at which the gross redemption yield on the Notes of the applicable series, if they were to be purchased at such price on the third dealing day prior to the date fixed for redemption, would be equal to the gross redemption yield on such dealing day of the Reference Bond (as defined below) on the basis of the middle market price of the Reference Bond prevailing at 11:00 a.m. (London time) on such dealing day as determined by the Company or an investment bank appointed by the Company.

"*Reference Bond*" means, in relation to any Treasury Rate calculation, a United Kingdom government bond whose maturity is closest to the maturity of the Notes of the applicable series, or if the Company or an investment bank appointed by the Company considers that such similar bond is not in issue, such other United Kingdom government bond as the Company or an investment bank appointed by the Company, with the advice of three brokers of, and/or market makers in, United Kingdom government bonds selected by the Company or an investment bank appointed by the Company, determine to be appropriate for determining such Treasury Rate.

"*Remaining Scheduled Payments*" means, with respect to each Note of a series to be redeemed, the remaining scheduled payments of principal of and interest on the Note that would be due after the related

------

redemption date but for the redemption. If that redemption date is not an interest payment date with respect to the applicable series of Notes, the amount of the next succeeding scheduled interest payment on the Notes will be reduced by the amount of interest accrued on the Notes to the redemption date.

On and after the redemption date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with a paying agent or the trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date.

In the case of any partial redemption, selection of the Notes of a series to be redeemed will be made by the trustee by lot or, with respect to the 2.900% 2026 Notes, pursuant to applicable depositary procedures and, with respect to the 4.375% 2029 Notes and the 2033 Notes, by such other method as the trustee in its sole discretion deems to be fair and appropriate.

**Payment of Additional Amounts** 

We will, subject to the exceptions and limitations set forth below, pay as additional interest on the Notes such additional amounts as are necessary so that the net payment by us or our paying agent of the principal of and interest on the Notes to a person that is a United States Alien, after deduction for any present or future tax, assessment or governmental charge of the United States or a political subdivision or taxing authority thereof or therein, imposed by withholding with respect to the payment, will not be less than the amount that would have been payable in respect of the Notes had no withholding or deduction been required. As used herein, "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust.

Our obligation to pay additional amounts shall not apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner, or a fiduciary, settlor, beneficiary or member of the beneficial owner if the beneficial owner is an estate, trust or partnership, or a person holding a power over an estate or trust administered by a fiduciary holder:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) is or was present or engaged in a trade or business in the United States, has or had a permanent establishment in the United States, or has any other present or former connection with the United States or any political subdivision or taxing authority thereof or therein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) is or was a citizen or resident or is or was treated as a resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) is or was a foreign or domestic personal holding company, a passive foreign investment company or a controlled foreign corporation with respect to the United States or is or was a corporation that has accumulated earnings to avoid United States federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) is or was a bank receiving interest described in Section 881(c)(3)(A) of the Internal Revenue Code of 1986, as amended (the "Code"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) is or was an actual or constructive owner of 10% or more of the total combined voting power of all classes of stock of AT&T entitled to vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) to any holder that is not the sole beneficial owner of the Notes, or a portion thereof, or that is a fiduciary or partnership, but only to the extent that the beneficial owner, a beneficiary or settlor with respect to the fiduciary, or a member of the partnership would not have been entitled to the payment of an additional amount had such beneficial owner, beneficiary, settlor or member received directly its beneficial or distributive share of the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of the Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) to any tax, assessment or governmental charge that is imposed other than by deduction or withholding by AT&T or a paying agent from the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) to any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that is announced or becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar tax, assessment or governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) to any tax, assessment or other governmental charge any paying agent (which term may include us) must withhold from any payment of principal of or interest on any Note, if such payment can be made without such withholding by any other paying agent; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) in the case of any combination of the above items.

In addition, any amounts to be paid on the Notes will be paid net of any deduction or withholding imposed or required pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code, and no additional amounts will be required to be paid on account of any such deduction or withholding.

The Notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable. Except as specifically provided under this heading "-Payment of Additional Amounts" and under the heading "-Redemption Upon a Tax Event," we do not have to make any payment with respect to any tax, assessment or governmental charge imposed by any government or a political subdivision or taxing authority.

Any reference in the terms of the Notes of each series to any amounts in respect of the Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

**Redemption Upon a Tax Event** 

If (a) we become or will become obligated to pay additional amounts with respect to any Notes as described herein under the heading "-Payment of Additional Amounts" as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein), or any change in, or amendments to, any official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective, on or after March 21, 2016 with respect to the 4.375% 2029 Notes and the 2033 Notes and September 6, 2018 with respect to the 2.900% 2026 Notes or (b) a taxing authority of the United States takes an action on or after March 21, 2016 with respect to the 4.375% 2029 Notes and the 2033 Notes and September 6, 2018 with respect to the 2.900% 2026 Notes, whether or not with respect to us or any of our affiliates, that results in a substantial probability that we will or may be required to pay such additional amounts, then we may, at our option, redeem, as a whole, but not in part, the applicable series of Notes on any interest payment date on not less than 30 nor more than 60 calendar days' prior notice, at a redemption price equal to 100% of their principal amount, together with interest accrued thereon to the date fixed for redemption. No redemption pursuant to (b) above may be made unless we shall have received an opinion of independent counsel to the effect that an act taken by a taxing authority of the United States results in a substantial probability that we will or may be required to pay the additional amounts described herein under the heading "-Payment of Additional Amounts" and we shall have delivered to the trustee a certificate, signed by a duly authorized officer, stating that based on such opinion we are entitled to redeem the Notes pursuant to their terms.

**Further Issues** 

We may from time to time, without notice to or the consent of the holders of any series of the Notes, create and issue further notes ranking equally and ratably with such series in all respects, or in all respects except for the payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date of those further notes. Any further notes will have the same terms as to status, redemption or otherwise as, and will be fungible for United States federal income tax purposes with, the Notes of the applicable series. Any further notes shall be issued pursuant to a resolution of our board of directors, a supplement to the Indenture, or under an officers' certificate pursuant to the Indenture.

**Governing Law** 

The Notes will be governed by and interpreted in accordance with the laws of the State of New York.

**Special Situations Covered by Our Indenture**

***Mergers and Similar Transactions***

We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company. However, we may not take any of these actions unless all the following conditions are met:

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Where we merge out of existence or sell our assets, the company we merge into or sell to may not be organized under the laws of a foreign country. It must be a corporation organized under the laws of the United States, any State thereof, or the District of Columbia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company we merge into or sell to must agree to be legally responsible for our debt securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merger, sale of assets or other transaction must not cause a default on the securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described below under "- Default and Related Matters - Events of Default - What Is an Event of Default?" A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded.

Further, we may buy substantially all of the assets of another company without complying with any of the foregoing conditions.

***Modification and Waiver of Holders' Contractual Rights***

Under certain circumstances, we can make changes to the Indenture and the securities (including the Notes). Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

*Changes Requiring Approval of Holders.* First, there are changes that cannot be made to the securities without specific approval of holders. The following is a list of those types of changes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the percentage of holders of securities who must consent to a waiver or amendment of the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the rate of interest on any security or change the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the principal due on any security or change the fixed maturity of any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to waive a default in the payment of principal or interest on any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the currency of payment on a security, unless the security provides for payment in a currency that ceases to exist;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of convertible or exchangeable securities, to make changes to conversion or exchange rights that would be adverse to the interests of holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the right of holders to waive an existing default by majority vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the amount of principal or interest payable to holders following a default or change any conversion or exchange rights, or impair the right of holders to sue for payment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change to this list of changes that requires specific approval of holders.

*Changes Requiring a Majority Vote.* The second type of change to the Indenture and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except as set forth in the following paragraph. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain each holder's individual consent to the waiver.

*Changes Not Requiring Approval of Holders.* The third type of change does not require any vote by holders of securities. This type includes, among others, clarifications of ambiguous contract terms, changes to make securities payable in U.S. dollars (if the stated denomination ceases to exist) and other changes that would not materially adversely affect holders of the securities.

*Further Details Concerning Voting.* When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent determined on the date of original issuance of these securities.

------

Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for the applicable holders money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the Indenture. However, the Indenture does not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

***Holders who hold in "street name" and other indirect holders, including holders of any securities issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the Indenture or the securities or request a waiver.***

**Discharge of Our Obligations**

We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for the applicable holders with the trustee and certain other conditions are met. The deposit must be held in trust for the benefit of all direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities.

If we accomplish full discharge, as described above, holders will have to rely solely on the trust deposit for repayment of the securities. Holders could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the trustee and holders against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations.

**Liens on Assets**

The Indenture does not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

**Default and Related Matters**

***Ranking Compared to Other Creditors***

The securities are not secured by any of our property or assets. Accordingly, ownership of securities means each holder is one of our unsecured creditors. The securities are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee has a right to receive payment for its administrative services prior to any payment to security holders after a default.

***Events of Default***

Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

*What Is an Event of Default?* The term "event of default" with respect to any series of securities means any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any interest payment on the securities of such series when it is due, and we do not cure this default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any payment of principal when it is due at the maturity of such series of securities or upon redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to comply with any of our other agreements regarding a particular series of securities or with a supplemental indenture, and after we have been notified of the default by the trustee or holders of 25% in principal amount of the series, we do not cure the default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We file for bankruptcy, or other events in bankruptcy, insolvency or reorganization occur.

***Remedies if an Event of Default Occurs***

------

Holders and the trustee will have the following remedies if an event of default occurs:

*Acceleration.* If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived.

*Special Duties of Trustee.* If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the Indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

*Other Remedies of Trustee.* If an event of default occurs, the trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the Indenture, including bringing a lawsuit.

*Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests*. The trustee is not required to take any action under the Indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an "indemnity". If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the Indenture.

*Individual Actions Holders May Take if the Trustee Fails to Act.* Before a holder bypasses the trustee and brings such holder's own lawsuit or other formal legal action or take other steps to enforce such holder's rights or protect such holder's interests relating to the securities, the following must occur:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such holder must give the trustee written notice that an event of default has occurred and remains uncured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The holders of 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer indemnity reasonably satisfactory to the Trustee against the cost and other liabilities of taking that action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the 60-day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with the request.

However, a holder is entitled at any time to bring an individual lawsuit for the payment of the money due on such holder's security on or after its due date.

***Waiver of Default***

The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on a holder's debt security, however, without such holder's individual approval.

***We Will Give the Trustee Information About Defaults Annually***

Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the Indenture and all the securities under it, or else specifying any default.

The trustee may withhold from holders notice of any uncured default, except for payment defaults, if it determines that withholding notice is in holders' interest.

**Holders who hold in "street name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to make or cancel a declaration of acceleration.**

**Regarding the Trustee**

------

The Bank of New York Mellon Trust Company, N.A. is the trustee under the Indenture. In addition, affiliates of The Bank of New York Mellon Trust Company, N.A. may perform various commercial banking and investment banking services for us and our subsidiaries from time to time in the ordinary course of business.

The Notes are unsecured and unsubordinated obligations and rank *pari passu* with all other indebtedness issued under our Indenture. Each series of Notes constitutes a separate series under the Indenture. The Notes are issued in fully registered form only and in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. Principal and interest payments on the Notes are payable by us in euro. Payments of principal, interest and additional amounts, if any, in respect of the Notes will be made to Euroclear System, Clearstream Banking S.A. or such nominee or common depositary, as the case may be, as registered holder thereof.

For purposes of the Notes, a "business day" means any day that is not a Saturday or Sunday and that in the City of New York or the City of London, is not a day on which banking institutions are generally authorized or obligated by law to close, and is a day on which the Trans-European Automated Real-time Gross Settlement Express Transfer (TARGET) System, or any successor thereto, operates.

**Interest**

The 3.550% 2025 Notes bear interest at the rate of 3.550% per annum, the 3.950% 2031 Notes bear interest at the rate of 3.950% per annum and the 4.300% 2034 Notes bear interest at the rate of 4.300% per annum.

We pay interest on (i) the 3.550% 2025 Notes and the 4.300% 2034 Notes annually in arrears on each November 18, commencing on November 18, 2023, and (ii) the 3.950% 2031 Notes annually in arrears on each April 30, commencing on April 30, 2024, in each case to the persons in whose names the Notes are registered at the close of business on the business day preceding the interest payment date. The 3.550% 2025 Notes matured on November 18, 2025, the 3.950% 2031 Notes will mature on April 30, 2031 and the 4.300% 2034 Notes will mature on November 18, 2034.

Interest on the Notes will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes (or May 18, 2023, if no interest has been paid on the Notes), to but excluding the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

**Optional Redemption**

Each series of Notes may be redeemed at any time prior to the applicable Par Call Date (as set forth in the table below), as a whole or in part, at our option, at any time and from time to time on at least 5 days', but not more than 40 days', prior notice sent to the registered address of each holder of the Notes of such series to be redeemed. The redemption price will be calculated by us and will be equal to the greater of (1) 100% of the principal amount of the Notes of such series to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) discounted to the redemption date, on an annual basis (ACTUAL/ACTUAL (ICMA)), at a rate equal to the sum of the Treasury Rate (as defined below) plus a number of basis points equal to the applicable Make-Whole Spread (as set forth in the table below). In the case of each of clauses (1) and (2), accrued but unpaid interest will be payable to, but excluding, the redemption date. At any time on or after the applicable Par Call Date (as set forth in the table below), the Notes may be redeemed, as a whole or in part, at our option, at any time and from time to time, on at least 5 days', but not more than 40 days', prior notice sent to the registered address of each holder of the Notes of such series to be redeemed, at a redemption price equal to 100% of the principal amount of such series of Notes to be redeemed. Accrued but unpaid interest will be payable to, but excluding, the redemption date.

&nbsp;&nbsp;&nbsp;&nbsp;*"Treasury Rate"* means the price, expressed as a percentage, at which the gross redemption yield on the Notes of the applicable series, if they were to be purchased at such price on the third dealing day prior to the date fixed for redemption, would be equal to the gross redemption yield on such dealing day of the applicable Reference Bond (as defined below) on the basis of the middle market price of the Reference Bond prevailing at 11:00 a.m. (London time) on such dealing day as determined by us or an investment bank appointed by us.

*"Reference Bond"* means, in relation to any Treasury Rate calculation, a German government bond whose maturity is closest to the maturity of the Notes of the applicable series, or if we or an investment bank appointed by us considers that such similar bond is not in issue, such other German government bond as we or an investment bank appointed by us, with the advice of three brokers of, and/or market makers in, German government bonds selected by us or an investment bank appointed by us, determine to be appropriate for determining such Treasury Rate.

*"Remaining Scheduled Payments"* means, with respect to each Note of a series to be redeemed, the remaining scheduled payments of principal and interest on such Note that, but for the redemption, would be due after the related redemption date through to the applicable Par Call Date, assuming the applicable series of Notes matured on the Par Call Date (not including any portion of payments of interest accrued as of the redemption date). If that redemption date is not an interest payment date with respect to the applicable series of Notes, the amount of the next succeeding scheduled interest payment on the Notes will be reduced by the amount of interest accrued on the Notes to the redemption date.&nbsp;&nbsp;&nbsp;&nbsp;

On and after the redemption date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with our paying agent or the trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date.

Any redemption or notice may, at our discretion, be subject to one or more conditions precedent and, at our discretion, the redemption date may be delayed until such time as any or all such conditions precedent included at our discretion shall be satisfied (or waived by us) or the redemption date may not occur and such notice may be rescinded if all such conditions precedent included at our discretion shall not have been satisfied (or waived by us).

In the case of any partial redemption, selection of the Notes of a series to be redeemed will be made by the trustee by lot or pursuant to applicable depositary procedures.

<br>**Payment of Additional Amounts**

We will, subject to the exceptions and limitations set forth below, pay as additional interest on the Notes such additional amounts as are necessary so that the net payment by us or our paying agent of the principal of and interest on the Notes to a person that is a United States Alien, after deduction for any present or future tax, assessment or governmental charge of the United States or a political subdivision or taxing authority thereof or therein, imposed by withholding with respect to the payment, will not be less than the amount that would have been payable in respect of the Notes had no withholding or deduction been required. As used herein, "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust.

------

Our obligation to pay additional amounts shall not apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner, or a fiduciary, settlor, beneficiary or member of the beneficial owner if the beneficial owner is an estate, trust or partnership, or a person holding a power over an estate or trust administered by a fiduciary holder:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) is or was present or engaged in a trade or business in the United States, has or had a permanent establishment in the United States, or has any other present or former connection with the United States or any political subdivision or taxing authority thereof or therein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) is or was a citizen or resident or is or was treated as a resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) is or was a foreign or domestic personal holding company, a passive foreign investment company or a controlled foreign corporation with respect to the United States or is or was a corporation that has accumulated earnings to avoid United States federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) is or was a bank receiving interest described in Section 881(c)(3)(A) of the Internal Revenue Code of 1986, as amended (the "Code"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) is or was an actual or constructive owner of 10% or more of the total combined voting power of all classes of stock of AT&T entitled to vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) to any holder that is not the sole beneficial owner of the Notes, or a portion thereof, or that is a fiduciary or partnership, but only to the extent that the beneficial owner, a beneficiary or settlor with respect to the fiduciary, or a member of the partnership would not have been entitled to the payment of an additional amount had such beneficial owner, beneficiary, settlor or member received directly its beneficial or distributive share of the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of the Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) to any tax, assessment or governmental charge that is imposed other than by deduction or withholding by AT&T or a paying agent from the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) to any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that is announced or becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar tax, assessment or governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) to any tax, assessment or other governmental charge any paying agent (which term may include us) must withhold from any payment of principal of or interest on any Note, if such payment can be made without such withholding by any other paying agent; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) in the case of any combination of the above items.

In addition, any amounts to be paid on the Notes will be paid net of any deduction or withholding imposed or required pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code, and no additional amounts will be required to be paid on account of any such deduction or withholding.

------

The Notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable. Except as specifically provided under this heading "—Payment of Additional Amounts" and under the heading "—Redemption Upon a Tax Event," we do not have to make any payment with respect to any tax, assessment or governmental charge imposed by any government or a political subdivision or taxing authority.

Any reference in the terms of the Notes of each series to any amounts in respect of the Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

**Redemption Upon a Tax Event**

If (a) we become or will become obligated to pay additional amounts with respect to any Notes as described herein under the heading "—Payment of Additional Amounts" as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein), or any change in, or amendments to, any official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective, on or after May 11, 2023or (b) a taxing authority of the United States takes an action on or after May 11, 2023, whether or not with respect to us or any of our affiliates, that results in a substantial probability that we will or may be required to pay such additional amounts, then we may, at our option, redeem, as a whole, but not in part, the applicable series of Notes on any interest payment date on not less than 5 nor more than 40 calendar days' prior notice, at a redemption price equal to 100% of their principal amount, together with interest accrued thereon to, but excluding, the date fixed for redemption. No redemption pursuant to (b) above may be made unless we shall have received an opinion of independent counsel to the effect that an act taken by a taxing authority of the United States results in a substantial probability that we will or may be required to pay the additional amounts described herein under the heading "—Payment of Additional Amounts" and we shall have delivered to the trustee a certificate, signed by a duly authorized officer, stating that based on such opinion we are entitled to redeem the Notes pursuant to their terms.

**Further Issues**

We may from time to time, without notice to or the consent of the holders of a series of the Notes, create and issue further notes ranking equally and ratably with such series in all respects, or in all respects except for the payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date of those further notes. Any further notes will have the same terms as to status, redemption or otherwise as, and will be fungible for United States federal income tax purposes with, the Notes of the applicable series. Any further notes shall be issued pursuant to a resolution of our board of directors, a supplement to the Indenture, or under an officers' certificate pursuant to the Indenture.

**Governing Law**

The Notes will be governed by and constructed in accordance with the laws of the State of New York.

**Special Situations Covered by Our Indenture**

***Mergers and Similar Transactions***

We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company. However, we may not take any of these actions unless all the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Where we merge out of existence or sell our assets, the company we merge into or sell to may not be organized under the laws of a foreign country. It must be a corporation organized under the laws of the United States, any State thereof, or the District of Columbia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company we merge into or sell to must agree to be legally responsible for our debt securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merger, sale of assets or other transaction must not cause a default on the securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of

------

this no-default test, a default would include an event of default that has occurred and not been cured, as described below under "— Default and Related Matters — Events of Default — What Is an Event of Default?" A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded.

Further, we may buy substantially all of the assets of another company without complying with any of the foregoing conditions.

***Modification and Waiver of Your Contractual Rights***

Under certain circumstances, we can make changes to the indentures and the securities. Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

*Changes Requiring Your Approval.* First, there are changes that cannot be made to your securities without your specific approval. The following is a list of those types of changes:<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the percentage of holders of securities who must consent to a waiver or amendment of the applicable indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the rate of interest on any security or change the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the principal due on any security or change the fixed maturity of any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to waive a default in the payment of principal or interest on any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the currency of payment on a security, unless the security provides for payment in a currency that ceases to exist;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of convertible or exchangeable securities, to make changes to your conversion or exchange rights that would be adverse to your interests;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the right of holders to waive an existing default by majority vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the amount of principal or interest payable to you following a default or change your conversion or exchange rights, or impair your right to sue for payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change to this list of changes that requires your specific approval; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to modify any of the provisions of the subordinated indenture in a manner that adversely affects the superior position of the holders of senior indebtedness then outstanding.

*Changes Requiring a Majority Vote.* The second type of change to the indentures and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except as set forth in the following paragraph. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain your individual consent to the waiver.

*Changes Not Requiring Your Approval.* The third type of change does not require any vote by holders of securities. This type includes, among others, clarifications of ambiguous contract terms, changes to make securities payable in U.S. dollars (if the stated denomination ceases to exist) and other changes that would not materially adversely affect holders of the securities.

*Further Details Concerning Voting.* When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For original issue discount securities, we will use the principal amount that would be due and payable on the voting date if the maturity of the securities were accelerated to that date because of a default.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent determined on the date of original issuance of these securities.

------

Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for you money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the indentures. However, the indentures do not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

***Holders who hold in "street name" and other indirect holders, including holders of any securities issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the indentures or the securities or request a waiver.***

**Discharge of Our Obligations**

We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for you with the trustee and certain other conditions are met. The deposit must be held in trust for your benefit and the benefit of all other direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities.

If we accomplish full discharge, as described above, you will have to rely solely on the trust deposit for repayment of the securities. Holders could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the trustee and you against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations.

**Liens on Assets**

The indentures do not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

**Default and Related Matters**

***Ranking Compared to Other Creditors***

The securities are not secured by any of our property or assets. Accordingly, your ownership of securities means you are one of our unsecured creditors. The securities are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee under each indenture has a right to receive payment for its administrative services prior to any payment to security holders after a default.

***Events of Default***

Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

*What Is an Event of Default?* The term "event of default" with respect to any series of securities means any of the following:<br>

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any interest payment on a security when it is due, and we do not cure this default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any payment of principal when it is due at the maturity of any security or upon redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to comply with any of our other agreements regarding a particular series of securities or with a supplemental indenture, and after we have been notified of the default by the trustee or holders of 25% in principal amount of the series, we do not cure the default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We file for bankruptcy, or other events in bankruptcy, insolvency or reorganization occur.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Any other event of default described in the prospectus supplement occurs.

***Remedies if an Event of Default Occurs***

Holders and the trustee will have the following remedies if an event of default occurs:

*Acceleration.* If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived.

*Special Duties of Trustee.* If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the applicable indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

*Other Remedies of Trustee.* If an event of default occurs, the trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the applicable indenture, including bringing a lawsuit.

*Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests*. The trustee is not required to take any action under the applicable indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an "indemnity". If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the applicable indenture.

*Individual Actions You May Take if the Trustee Fails to Act.* Before a holder bypasses the trustee and brings such holder's own lawsuit or other formal legal action or takes other steps to enforce such holder's rights or protect such holder's interests relating to the securities, the following must occur:<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such holder must give the trustee written notice that an event of default has occurred and remains uncured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The holders of 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer indemnity reasonably satisfactory to the trustee against the cost and other liabilities of taking that action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the 60-day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with the request.

However, a holder is entitled at any time to bring an individual lawsuit for the payment of the money due on such holder's security on or after its due date.

***Waiver of Default***

------

The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on a holder's debt security, however, without such holder's individual approval.

***We Will Give the Trustee Information About Defaults Annually***

Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the indentures and all the securities under it, or else specifying any default.

The trustee may withhold from you notice of any uncured default, except for payment defaults, if it determines that withholding notice is in your interest.

**Holders who hold in "street name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to make or cancel a declaration of acceleration.**

**Regarding the Trustee**

The Bank of New York Mellon Trust Company, N.A. is the trustee under the Indenture. In addition, affiliates of The Bank of New York Mellon Trust Company, N.A. may perform various commercial banking and investment banking services for us and our subsidiaries from time to time in the ordinary course of business.

The Notes are unsecured and unsubordinated obligations and rank *pari passu* with all other indebtedness issued under our Indenture. Each series of Notes constitutes a separate series under the Indenture. The Notes are issued in fully registered form only and in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. Principal and interest payments on the Notes are payable by us in euro. Payments of principal, interest and additional amounts, if any, in respect of the Notes will be made to Euroclear System, Clearstream Banking S.A. or such nominee or common depositary, as the case may be, as registered holder thereof.

&nbsp;&nbsp;&nbsp;&nbsp;For purposes of the Notes, a business day means any day that is not a Saturday or Sunday and that, in the City of New York or the City of London, is not a day on which banking institutions are generally authorized or obligated by law to close, and is a day on which the Trans-European Real-time Gross Settlement Express Transfer (TARGET) System, or any successor thereto, operates.

**Interest**

The 3.150% 2030 Notes bear interest at the rate of 3.150% per annum, the 3.600% 2033 Notes bear interest at the rate of 3.600% per annum and the 4.050% 2037 Notes bear interest at the rate of 4.050% per annum.

We pay interest on the Notes annually in arrears on each June 1, commencing on June 1, 2025, to the persons in whose names the Notes are registered at the close of business on the business day preceding the interest payment date. The 3.150% 2030 Notes will mature on June 1, 2030, the 3.600% 2033 Notes will mature on June 1, 2033 and the 4.050% 2037 Notes will mature on June 1, 2037.

Interest on the Notes will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes (or March 31, 2025, if no interest has been paid on the Notes), to but excluding the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

**Optional Redemption**

------

Each series of Notes may be redeemed at any time prior to the applicable Par Call Date (as set forth in the table below), as a whole or in part, at our option, at any time and from time to time on at least 5 days', but not more than 40 days', prior notice sent to the registered address of each holder of the Notes of such series to be redeemed. The redemption price will be calculated by us and will be equal to the greater of (1) 100% of the principal amount of the Notes of such series to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) discounted to the redemption date, on an annual basis (ACTUAL/ACTUAL (ICMA)), at a rate equal to the sum of the Treasury Rate (as defined below) plus a number of basis points equal to the applicable Make-Whole Spread (as set forth in the table below). In the case of each of clauses (1) and (2), accrued but unpaid interest will be payable to, but excluding, the redemption date. At any time on or after the applicable Par Call Date (as set forth in the table below), the Notes may be redeemed, as a whole or in part, at our option, at any time and from time to time, on at least 5 days', but not more than 40 days', prior notice sent to the registered address of each holder of the Notes of such series to be redeemed, at a redemption price equal to 100% of the principal amount of such series of Notes to be redeemed. Accrued but unpaid interest will be payable to, but excluding, the redemption date.

---

| | | |
|:---|:---|:---|
| **Series** | **Par Call Date** | **Make-Whole Spread** |
| 3.150% 2030 Notes | May 1, 2030 | 15 bps |
| 3.600% 2033 Notes | March 1, 2033 | 15 bps |
| 4.050% 2037 Notes | March 1, 2037 | 20 bps |

---

&nbsp;&nbsp;&nbsp;&nbsp;"*Treasury Rate*" means the price, expressed as a percentage, at which the gross redemption yield on the Notes of the applicable series, if they were to be purchased at such price on the third dealing day prior to the date fixed for redemption, would be equal to the gross redemption yield on such dealing day of the applicable Reference Bond (as defined below) on the basis of the middle market price of the Reference Bond prevailing at 11:00 a.m. (London time) on such dealing day as determined by the Company or an investment bank appointed by the Company.

"*Reference Bond*" means, in relation to any Treasury Rate calculation, a German government bond whose maturity is closest to the maturity of the Notes of the applicable series, or if the Company or an investment bank appointed by the Company considers that such similar bond is not in issue, such other German government bond as the Company or an investment bank appointed by the Company, with the advice of three brokers of, and/or market makers in, German government bonds selected by the Company or an investment bank appointed by the Company, determine to be appropriate for determining such Treasury Rate.

"*Remaining Scheduled Payments*" means, with respect to each Note of a series to be redeemed, the remaining scheduled payments of principal and interest on such Note that, but for the redemption, would be due after the related redemption date through to the applicable Par Call Date, assuming the applicable series of Notes matured on the Par Call Date (not including any portion of payments of interest accrued as of the redemption date). If that redemption date is not an interest payment date with respect to the applicable series of Notes, the amount of the next succeeding scheduled interest payment on the Notes will be reduced by the amount of interest accrued on the Notes to the redemption date.&nbsp;&nbsp;&nbsp;&nbsp;

On and after the redemption date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with our paying agent or the trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date. The Trustee shall have no responsibility to calculate the redemption price or determine the Treasury Rate.

Any redemption or notice may, at our discretion, be subject to one or more conditions precedent and, at our discretion, the redemption date may be delayed until such time as any or all such conditions precedent included

------

at our discretion shall be satisfied (or waived by us) or the redemption date may not occur and such notice may be rescinded if all such conditions precedent included at our discretion shall not have been satisfied (or waived by us).

In the case of any partial redemption, selection of the Notes of a series to be redeemed will be made by the trustee by lot or pursuant to applicable depositary procedures.

<br>**Payment of Additional Amounts**

We will, subject to the exceptions and limitations set forth below, pay as additional interest on the Notes such additional amounts as are necessary so that the net payment by us or our paying agent of the principal of and interest on the Notes to a person that is a United States Alien, after deduction for any present or future tax, assessment or governmental charge of the United States or a political subdivision or taxing authority thereof or therein, imposed by withholding with respect to the payment, will not be less than the amount that would have been payable in respect of the Notes had no withholding or deduction been required. As used herein, "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust.

Our obligation to pay additional amounts shall not apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner, or a fiduciary, settlor, beneficiary or member of the beneficial owner if the beneficial owner is an estate, trust or partnership, or a person holding a power over an estate or trust administered by a fiduciary holder:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) is or was present or engaged in a trade or business in the United States, has or had a permanent establishment in the United States, or has any other present or former connection with the United States or any political subdivision or taxing authority thereof or therein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) is or was a citizen or resident or is or was treated as a resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) is or was a foreign or domestic personal holding company, a passive foreign investment company or a controlled foreign corporation with respect to the United States or is or was a corporation that has accumulated earnings to avoid United States federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) is or was a bank receiving interest described in Section 881(c)(3)(A) of the Internal Revenue Code of 1986, as amended (the "Code"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) is or was an actual or constructive owner of 10% or more of the total combined voting power of all classes of stock of AT&T entitled to vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) to any holder that is not the sole beneficial owner of the Notes, or a portion thereof, or that is a fiduciary or partnership, but only to the extent that the beneficial owner, a beneficiary or settlor with respect to the fiduciary, or a member of the partnership would not have been entitled to the payment of an additional amount had such beneficial owner, beneficiary, settlor or member received directly its beneficial or distributive share of the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of the Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) to any tax, assessment or governmental charge that is imposed other than by deduction or withholding by AT&T or a paying agent from the payment;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) to any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that is announced or becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar tax, assessment or governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) to any tax, assessment or other governmental charge any paying agent (which term may include us) must withhold from any payment of principal of or interest on any Note, if such payment can be made without such withholding by any other paying agent; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) in the case of any combination of the above items.

In addition, any amounts to be paid on the Notes will be paid net of any deduction or withholding imposed or required pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code, and no additional amounts will be required to be paid on account of any such deduction or withholding.

The Notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable. Except as specifically provided under this heading "—Payment of Additional Amounts" and under the heading "—Redemption Upon a Tax Event," we do not have to make any payment with respect to any tax, assessment or governmental charge imposed by any government or a political subdivision or taxing authority.

Any reference in the terms of the Notes of each series to any amounts in respect of the Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

**Redemption Upon a Tax Event**

If (a) we become or will become obligated to pay additional amounts with respect to any Notes as described herein under the heading "—Payment of Additional Amounts" as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein), or any change in, or amendments to, any official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective, on or after March 24, 2025 or (b) a taxing authority of the United States takes an action on or after March 24, 2025, whether or not with respect to us or any of our affiliates, that results in a substantial probability that we will or may be required to pay such additional amounts, then we may, at our option, redeem, as a whole, but not in part, the applicable series of Notes on any interest payment date on not less than 5 nor more than 40 calendar days' prior notice, at a redemption price equal to 100% of their principal amount, together with interest accrued thereon to, but excluding, the date fixed for redemption. No redemption pursuant to (b) above may be made unless we shall have received an opinion of independent counsel to the effect that an act taken by a taxing authority of the United States results in a substantial probability that we will or may be required to pay the additional amounts described herein under the heading "—Payment of Additional Amounts" and we shall have delivered to the trustee a certificate, signed by a duly authorized officer, stating that based on such opinion we are entitled to redeem the Notes pursuant to their terms.

**Further Issues**

We may from time to time, without notice to or the consent of the holders of any series of the Notes, create and issue further notes ranking equally and ratably with such series in all respects, or in all respects except for the payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date of those further notes. Any further notes will have the same terms as to status, redemption or otherwise as, and will be fungible for United States federal income tax purposes with, the Notes of the applicable series. Any further notes

------

shall be issued pursuant to a resolution of our board of directors, a supplement to the indenture, or under an officers' certificate pursuant to the indenture.

**Governing Law**

The Notes will be governed by and interpreted in accordance with the laws of the State of New York.

**Special Situations Covered by Our Indenture**

***Mergers and Similar Transactions***

We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company. However, we may not take any of these actions unless all the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Where we merge out of existence or sell our assets, the company we merge into or sell to may not be organized under the laws of a foreign country. It must be a corporation organized under the laws of the United States, any State thereof, or the District of Columbia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company we merge into or sell to must agree to be legally responsible for our debt securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merger, sale of assets or other transaction must not cause a default on the securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described below under "— Default and Related Matters — Events of Default — What Is an Event of Default?" A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded.

Further, we may buy substantially all of the assets of another company without complying with any of the foregoing conditions.

***Modification and Waiver of a Holder's Contractual Rights***

Under certain circumstances, we can make changes to the indentures and the securities. Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

*Changes Requiring a Holder's Approval.* First, there are changes that cannot be made to a holder's securities without the holder's specific approval. The following is a list of those types of changes:<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the percentage of holders of securities who must consent to a waiver or amendment of the applicable indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the rate of interest on any security or change the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the principal due on any security or change the fixed maturity of any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to waive a default in the payment of principal or interest on any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the currency of payment on a security, unless the security provides for payment in a currency that ceases to exist;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of convertible or exchangeable securities, to make changes to a holder's conversion or exchange rights that would be adverse to a holder's interests;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the right of holders to waive an existing default by majority vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the amount of principal or interest payable to a holder following a default or change a holder's conversion or exchange rights, or impair a holder's right to sue for payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change to this list of changes that requires a holder's specific approval; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to modify any of the provisions of the subordinated indenture in a manner that adversely affects the superior position of the holders of senior indebtedness then outstanding.

------

*Changes Requiring a Majority Vote.* The second type of change to the indentures and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except as set forth in the following paragraph. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain a holder's individual consent to the waiver.

*Changes Not Requiring a Holder's Approval.* The third type of change does not require any vote by holders of securities. This type includes, among others, clarifications of ambiguous contract terms, changes to make securities payable in U.S. dollars (if the stated denomination ceases to exist) and other changes that would not materially adversely affect holders of the securities.

*Further Details Concerning Voting.* When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For original issue discount securities, we will use the principal amount that would be due and payable on the voting date if the maturity of the securities were accelerated to that date because of a default.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent determined on the date of original issuance of these securities.

Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for a holder money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the indentures. However, the indentures do not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

***Holders who hold in "street name" and other indirect holders, including holders of any securities issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the indentures or the securities or request a waiver.***

**Discharge of Our Obligations**

We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for a holder with the trustee and certain other conditions are met. The deposit must be held in trust for a holder's benefit and the benefit of all other direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities and the prospectus supplement.

If we accomplish full discharge, as described above, a holder will have to rely solely on the trust deposit for repayment of the securities. A holder could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the trustee and a holder against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations.

**Liens on Assets**

------

The indentures do not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

**Default and Related Matters**

***Ranking Compared to Other Creditors***

The securities are not secured by any of our property or assets. Accordingly, a holder's ownership of securities means a holder is one of our unsecured creditors. The senior debt securities are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee under each indenture has a right to receive payment for its administrative services prior to any payment to security holders after a default.

***Events of Default***

Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

*What Is an Event of Default?* The term "event of default" with respect to any series of securities means any of the following:<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any interest payment on a security when it is due, and we do not cure this default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any payment of principal when it is due at the maturity of any security or upon redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to comply with any of our other agreements regarding a particular series of securities or with a supplemental indenture, and after we have been notified of the default by the trustee or holders of 25% in principal amount of the series, we do not cure the default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We file for bankruptcy, or other events in bankruptcy, insolvency or reorganization occur.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Any other event of default described in the prospectus supplement occurs.

***Remedies if an Event of Default Occurs***

Holders and the trustee will have the following remedies if an event of default occurs:

*Acceleration.* If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived.

*Special Duties of Trustee.* If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the applicable indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

*Other Remedies of Trustee.* If an event of default occurs, the trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the applicable indenture, including bringing a lawsuit.

*Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests*. The trustee is not required to take any action under the applicable indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an "indemnity". If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the applicable indenture.

------

*Individual Actions a Holder May Take if the Trustee Fails to Act.* Before a holder bypasses the trustee and brings their own lawsuit or other formal legal action or take other steps to enforce their rights or protect their interests relating to the securities, the following must occur:<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such holder must give the trustee written notice that an event of default has occurred and remains uncured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The holders of 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer indemnity reasonably satisfactory to the trustee against the cost and other liabilities of taking that action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the 60-day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with the request.

However, a holder is entitled at any time to bring an individual lawsuit for the payment of the money due on a holder's security on or after its due date.

***Waiver of Default***

The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on a holder's debt security, however, without a holder's individual approval.

***We Will Give the Trustee Information About Defaults Annually***

<br> Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the indentures and all the securities under it, or else specifying any default.

The trustee may withhold from a holder notice of any uncured default, except for payment defaults, if it determines that withholding notice is in a holder's interest.

***Holders who hold in "street name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to make or cancel a declaration of acceleration.***

**Regarding the Trustee**

The Bank of New York Mellon Trust Company, N.A. is the trustee under the Indenture. In addition, affiliates of The Bank of New York Mellon Trust Company, N.A. may perform various commercial banking and investment banking services for us and our subsidiaries from time to time in the ordinary course of business.

**DESCRIPTION OF THE FLOATING RATE GLOBAL NOTES DUE 2027**

*The following summary of AT&T's above referenced debt securities is based on and qualified by the indenture, dated as of May 15, 2013, with The Bank of New York Mellon Trust Company, N.A., acting as trustee (the "Indenture") and the Floating Rate Global Notes due 2027 (the "Notes"). For a complete description of the terms and provisions of the Notes, please refer to the Indenture, which is filed as an exhibit to AT&T's Annual Report on* 

------

*Form 10-K for the year ended December 31, 2025 and to the form of Notes, which is filed as an exhibit to the Form 8-A filed with the Securities and Exchange Commission on September 16, 2025.*

**General**

The Notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• were issued in an aggregate initial principal amount of €2,250,000,000, which remains outstanding, subject to our ability to issue additional Notes which may be of the same series as the Notes as described under "-Further Issues";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mature on September 16, 2027;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• bear interest at the applicable interest rate on the Notes in effect for each day of the Floating Rate Interest Period (as defined below) equal to the Applicable EURIBOR Rate plus 40 basis points (0.400%), payable quarterly in arrears;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are repayable at par at maturity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are redeemable by us in connection with certain tax events as described below under "-Redemption Upon a Tax Event"; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are not subject to any sinking fund.

The Notes are unsecured and unsubordinated obligations and will rank *pari passu* with all other indebtedness issued under our indenture. The Notes will constitute a single series under the indenture. The Notes are issued in fully registered form only and in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. Principal and interest payments on the Notes are payable by us in euro. Payments of principal, interest and additional amounts, if any, in respect of the Notes will be made to Euroclear System, Clearstream Banking S.A. or such nominee or common depositary, as the case may be, as registered holder thereof.

For purposes of the Notes, a business day means any day that is not a Saturday or Sunday and that, in the City of New York or the City of London, is not a day on which banking institutions are generally authorized or obligated by law to close, and is a day on which the Trans-European Automated Real-time Gross Settlement Express Transfer (TARGET) System, or any successor thereto, operates.

**Interest**

The Notes will bear interest from September 16, 2025 at a floating rate determined in the manner provided below, payable on March 16, June 16, September 16 and December 16 of each year (each such day, a "Floating Rate Interest Payment Date"), commencing on December 16, 2025, to the persons in whose names the Notes were registered at the close of business on the 15th day preceding the respective Floating Rate Interest Payment Date, subject to certain exceptions. The per annum interest rate on the Notes (the "Floating Interest Rate") in effect for each day of a Floating Rate Interest Period (as defined below) will be equal to the Applicable EURIBOR Rate plus 40 basis points (0.400%). The Floating Interest Rate for each Floating Rate Interest Period will be set on March 16, June 16, September 16 and December 16 of each year, and will be set for the initial Floating Rate Interest Period on September 16, 2025 (each such date, a "Floating Rate Interest Reset Date") until the principal on the Notes is paid or made available for payment (the "Floating Rate Principal Payment Date"). If any Floating Rate Interest Reset Date (other than the initial Floating Rate Interest Reset Date occurring on September 16, 2025) and Floating Rate Interest Payment Date would otherwise be a day that is not a EURIBOR business day, other than the interest payment date that is also the date of maturity, such Floating Rate Interest Reset Date and Floating Rate Interest Payment Date shall be the next succeeding EURIBOR business day, unless the next succeeding EURIBOR business day is in the next succeeding calendar month, in which case such Floating Rate Interest Reset Date and Floating Rate Interest

------

Payment Date shall be the immediately preceding EURIBOR business day; and provided further, that if the date of maturity is not a EURIBOR business day, payment of principal and interest will be made on the next succeeding business day and no interest will accrue for the period from and after such date of maturity.

"EURIBOR business day" means any day that is not a Saturday or Sunday and that, in the City of New York or the City of London, is not a day on which banking institutions are generally authorized or obligated by law to close, and is a day on which the TARGET System, or any successor thereto, operates.

"Floating Rate Interest Period" shall mean the period from and including a Floating Rate Interest Reset Date to but excluding the next succeeding Floating Rate Interest Reset Date and, in the case of the last such period, from and including the Floating Rate Interest Reset Date immediately preceding the maturity date or Floating Rate Principal Payment Date, as the case may be, to but not including such maturity date or Floating Rate Principal Payment Date, as the case may be. If the Floating Rate Principal Payment Date or maturity date is not a EURIBOR business day, then the principal amount of the Notes plus accrued and unpaid interest thereon shall be paid on the next succeeding EURIBOR business day and no interest shall accrue for the maturity date, Floating Rate Principal Payment Date or any day thereafter.

The "Applicable EURIBOR Rate" shall mean the rate determined in accordance with the following provisions:

(1) Two prior TARGET days on which dealings in deposits in euros are transacted in the euro-zone interbank market preceding each Floating Rate Interest Reset Date (each such date, an "Interest Determination Date"), The Bank of New York Mellon Trust Company, N.A. (the "Calculation Agent"), as agent for AT&T, will determine the Applicable EURIBOR Rate which shall be the rate for deposits in euro having a maturity of three months commencing on the first day of the applicable interest period that appears on the Bloomberg Screen BBAM Page as of 11:00 a.m., Brussels time, on such Interest Determination Date. "Bloomberg Screen BBAM Page" means the display designated on page "BBAM" on Bloomberg (or such other page as may replace the "BBAM" page on that service or any successor service for the purpose of displaying euro-zone interbank offered rates for euro-denominated deposits of major banks). If the Applicable EURIBOR Rate on such Interest Determination Date does not appear on the Bloomberg Screen BBAM Page, the Applicable EURIBOR Rate will be determined as described in (2) below.

(2) With respect to an Interest Determination Date for which the Applicable EURIBOR Rate does not appear on the Bloomberg Screen BBAM Page as specified in (1) above, the Applicable EURIBOR Rate will be determined on the basis of the rates at which deposits in euro are offered by four major banks in the euro-zone interbank market selected by AT&T (the "Reference Banks") at approximately 11:00 a.m., Brussels time, on such Interest Determination Date to prime banks in the euro-zone interbank market having a maturity of three months, and in a principal amount equal to an amount of not less than €1,000,000 that is representative for a single transaction in such market at such time. AT&T or its designee will request the principal euro-zone office of each of such Reference Banks to provide a quotation of its rate. If at least two such quotations are provided, the Applicable EURIBOR Rate on such Interest Determination Date will be the arithmetic mean (rounded upwards) of such quotations. If fewer than two quotations are provided, the Applicable EURIBOR Rate on such Interest Determination Date will be the arithmetic mean (rounded upwards) of the rates quoted by three major banks in the euro-zone selected by AT&T at approximately 11:00 a.m., Brussels time, on such Interest Determination Date for loans in euro to leading European banks, having a maturity of three months, and in a principal amount equal to an amount of not less than €1,000,000 that is representative for a single transaction in such market at such time; provided, however, that if the banks so selected as aforesaid by AT&T are not quoting as mentioned in this sentence, the relevant Floating Interest Rate for

------

the Floating Rate Interest Period commencing on the Floating Rate Interest Reset Date following such Interest Determination Date will be the Floating Interest Rate in effect on such Interest Determination Date (i.e., the same as the rate determined for the immediately preceding Floating Rate Interest Reset Date).

The amount of interest for each day that the Notes are outstanding (the "Daily Interest Amount") will be calculated by dividing the Floating Interest Rate in effect for such day by 360 and multiplying the result by the principal amount of the Notes (known as the "Actual/360" day count). The amount of interest to be paid on the Notes for any Floating Rate Interest Period will be calculated by adding the Daily Interest Amounts for each day in such Floating Rate Interest Period.

The Floating Interest Rate and amount of interest to be paid on the Notes for each Floating Rate Interest Period will be determined by the Calculation Agent. The Floating Interest Rate will in no event be lower than zero or higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application. The Calculation Agent will, upon the request of any holder of the Notes, provide the interest rate then in effect with respect to the Notes. All calculations made by the Calculation Agent shall in the absence of manifest error be conclusive for all purposes and binding on AT&T and the holders of the Notes. So long as the Applicable EURIBOR Rate is required to be determined with respect to the Notes, there will at all times be a Calculation Agent. In the event that any then acting Calculation Agent shall be unable or unwilling to act, or that such Calculation Agent shall fail to duly establish the Applicable EURIBOR Rate for any Floating Rate Interest Period, or that AT&T proposes to remove such Calculation Agent, AT&T shall appoint itself or another person which is a bank, trust company, investment banking firm or other financial institution to act as the Calculation Agent.

**Payment of Additional Amounts**

We will, subject to the exceptions and limitations set forth below, pay as additional interest on the Notes such additional amounts as are necessary so that the net payment by us or our paying agent of the principal of and interest on the Notes to a person that is a United States Alien, after deduction for any present or future tax, assessment or governmental charge of the United States or a political subdivision or taxing authority thereof or therein, imposed by withholding with respect to the payment, will not be less than the amount that would have been payable in respect of the Notes had no withholding or deduction been required. As used herein, "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust.

Our obligation to pay additional amounts shall not apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner, or a fiduciary, settlor, beneficiary or member of the beneficial owner if the beneficial owner is an estate, trust or partnership, or a person holding a power over an estate or trust administered by a fiduciary holder:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) is or was present or engaged in a trade or business in the United States, has or had a permanent establishment in the United States, or has any other present or former connection with the United States or any political subdivision or taxing authority thereof or therein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) is or was a citizen or resident or is or was treated as a resident of the United States;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) is or was a foreign or domestic personal holding company, a passive foreign investment company or a controlled foreign corporation with respect to the United States or is or was a corporation that has accumulated earnings to avoid United States federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) is or was a bank receiving interest described in Section 881(c)(3)(A) of the Internal Revenue Code of 1986, as amended (the "Code"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) is or was an actual or constructive owner of 10% or more of the total combined voting power of all classes of stock of AT&T entitled to vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) to any holder that is not the sole beneficial owner of the Notes, or a portion thereof, or that is a fiduciary or partnership, but only to the extent that the beneficial owner, a beneficiary or settlor with respect to the fiduciary, or a member of the partnership would not have been entitled to the payment of an additional amount had such beneficial owner, beneficiary, settlor or member received directly its beneficial or distributive share of the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of the Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) to any tax, assessment or governmental charge that is imposed other than by deduction or withholding by AT&T or a paying agent from the payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) to any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that is announced or becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar tax, assessment or governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) to any tax, assessment or other governmental charge any paying agent (which term may include us) must withhold from any payment of principal of or interest on any Note, if such payment can be made without such withholding by any other paying agent; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) in the case of any combination of the above items.

In addition, any amounts to be paid on the Notes will be paid net of any deduction or withholding imposed or required pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code, and no additional amounts will be required to be paid on account of any such deduction or withholding.

The Notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable. Except as specifically provided under this heading "—Payment of Additional Amounts" and under the heading "—Redemption Upon a Tax Event," we do not have to make any payment with respect to any tax, assessment or governmental charge imposed by any government or a political subdivision or taxing authority.

------

Any reference in the terms of the Notes to any amounts in respect of the Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

**Redemption Upon a Tax Event**

If (a) we become or will become obligated to pay additional amounts with respect to any Notes as described herein under the heading "—Payment of Additional Amounts" as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein), or any change in, or amendments to, any official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective, on or after September 9, 2025 or (b) a taxing authority of the United States takes an action on or after September 9, 2025, whether or not with respect to us or any of our affiliates, that results in a substantial probability that we will or may be required to pay such additional amounts, then we may, at our option, redeem, as a whole, but not in part, the Notes on any interest payment date on not less than 5 nor more than 40 calendar days' prior notice, at a redemption price equal to 100% of their principal amount, together with interest accrued thereon to the date fixed for redemption. No redemption pursuant to (b) above may be made unless we shall have received an opinion of independent counsel to the effect that an act taken by a taxing authority of the United States results in a substantial probability that we will or may be required to pay the additional amounts described herein under the heading "—Payment of Additional Amounts" and we shall have delivered to the trustee a certificate, signed by a duly authorized officer, stating that based on such opinion we are entitled to redeem the Notes pursuant to their terms.

**Further Issues**

We may from time to time, without notice to or the consent of the holders of the Notes, create and issue further notes ranking equally and ratably with such Notes in all respects, or in all respects except for the payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date of those further notes. Any further notes will have the same terms as to status, redemption or otherwise as, and will be fungible for United States federal income tax purposes with, the Notes. Any further notes shall be issued pursuant to a resolution of our board of directors, a supplement to the indenture, or under an officers' certificate pursuant to the indenture.

**Governing Law**

The Notes will be governed by and interpreted in accordance with the laws of the State of New York.

**Special Situations Covered by Our Indenture**

***Mergers and Similar Transactions***

We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company. However, we may not take any of these actions unless all the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Where we merge out of existence or sell our assets, the company we merge into or sell to may not be organized under the laws of a foreign country. It must be a corporation organized under the laws of the United States, any State thereof, or the District of Columbia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The company we merge into or sell to must agree to be legally responsible for our debt securities.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merger, sale of assets or other transaction must not cause a default on the securities, and we must not already be in default, unless the merger or other transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described below under "— Default and Related Matters — Events of Default — What Is an Event of Default?" A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded.

Further, we may buy substantially all of the assets of another company without complying with any of the foregoing conditions.

***Modification and Waiver of Your Contractual Rights***

Under certain circumstances, we can make changes to the indentures and the securities. Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

*Changes Requiring Your Approval.* First, there are changes that cannot be made to your securities without your specific approval. The following is a list of those types of changes:<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the percentage of holders of securities who must consent to a waiver or amendment of the applicable indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the rate of interest on any security or change the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the principal due on any security or change the fixed maturity of any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to waive a default in the payment of principal or interest on any security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the currency of payment on a security, unless the security provides for payment in a currency that ceases to exist;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of convertible or exchangeable securities, to make changes to your conversion or exchange rights that would be adverse to your interests;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to change the right of holders to waive an existing default by majority vote;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to reduce the amount of principal or interest payable to you following a default or change your conversion or exchange rights, or impair your right to sue for payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change to this list of changes that requires your specific approval; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to modify any of the provisions of the subordinated indenture in a manner that adversely affects the superior position of the holders of senior indebtedness then outstanding.

*Changes Requiring a Majority Vote.* The second type of change to the indentures and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except as set forth in the following paragraph. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain your individual consent to the waiver.

*Changes Not Requiring Your Approval.* The third type of change does not require any vote by holders of securities. This type includes, among others, clarifications of ambiguous contract terms, changes to make securities payable in U.S. dollars (if the stated denomination ceases to exist) and other changes that would not materially adversely affect holders of the securities.

------

*Further Details Concerning Voting.* When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For original issue discount securities, we will use the principal amount that would be due and payable on the voting date if the maturity of the securities were accelerated to that date because of a default.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent determined on the date of original issuance of these securities.

Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for you money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the indentures. However, the indentures do not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

***Holders who hold in "street name" and other indirect holders, including holders of any securities issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the indentures or the securities or request a waiver.***

**Discharge of Our Obligations**

We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for you with the trustee and certain other conditions are met. The deposit must be held in trust for your benefit and the benefit of all other direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities.

If we accomplish full discharge, as described above, you will have to rely solely on the trust deposit for repayment of the securities. Holders could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the trustee and you against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations.

**Liens on Assets**

The indentures do not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

**Default and Related Matters**

***Ranking Compared to Other Creditors***

------

The securities are not secured by any of our property or assets. Accordingly, your ownership of securities means you are one of our unsecured creditors. The securities are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee under each indenture has a right to receive payment for its administrative services prior to any payment to security holders after a default.

***Events of Default***

Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

*What Is an Event of Default?* The term "event of default" with respect to any series of securities means any of the following:<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any interest payment on a security when it is due, and we do not cure this default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to make any payment of principal when it is due at the maturity of any security or upon redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We fail to comply with any of our other agreements regarding a particular series of securities or with a supplemental indenture, and after we have been notified of the default by the trustee or holders of 25% in principal amount of the series, we do not cure the default within 90 days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We file for bankruptcy, or other events in bankruptcy, insolvency or reorganization occur.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Any other event of default described in the prospectus supplement occurs.

***Remedies if an Event of Default Occurs***

Holders and the trustee will have the following remedies if an event of default occurs:

*Acceleration.* If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived.

*Special Duties of Trustee.* If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the applicable indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

*Other Remedies of Trustee.* If an event of default occurs, the trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the applicable indenture, including bringing a lawsuit.

*Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests*. The trustee is not required to take any action under the applicable indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an "indemnity". If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the applicable indenture.

------

*Individual Actions You May Take if the Trustee Fails to Act.* Before a holder bypasses the trustee and brings such holder's own lawsuit or other formal legal action or takes other steps to enforce such holder's rights or protect such holder's interests relating to the securities, the following must occur:<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such holder must give the trustee written notice that an event of default has occurred and remains uncured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The holders of 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer indemnity reasonably satisfactory to the trustee against the cost and other liabilities of taking that action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the 60-day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with the request.

However, a holder is entitled at any time to bring an individual lawsuit for the payment of the money due on such holder's security on or after its due date.

***Waiver of Default***

The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on a holder's debt security, however, without such holder's individual approval.

***We Will Give the Trustee Information About Defaults Annually***

Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the indentures and all the securities under it, or else specifying any default.

The trustee may withhold from you notice of any uncured default, except for payment defaults, if it determines that withholding notice is in your interest.

**Holders who hold in "street name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to make or cancel a declaration of acceleration.**

**Regarding the Trustee**

The Bank of New York Mellon Trust Company, N.A. is the trustee under the Indenture. In addition, affiliates of The Bank of New York Mellon Trust Company, N.A. may perform various commercial banking and investment banking services for us and our subsidiaries from time to time in the ordinary course of business.

**AT&T Inc.**

**Non-Employee Director Stock and Deferral Plan**

**Article 1. Purpose**

The purpose of the Non-Employee Director Stock and Deferral Plan (the "Plan") (formerly the Deferred Compensation Plan for Non-Employee Directors) is to promote the achievement of long-term objectives of AT&T Inc. by linking the personal interests of Non-Employee Directors to those of the Company's stockholders and to attract and retain Non-Employee Directors of outstanding competence.

**Article 2. Definitions**

Whenever used in the Plan, the following terms shall have the meanings set forth below and, when the defined meaning is intended, the initial letter of the word is capitalized:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)**"Annual Retainer" or "Retainer"** means the payments made to Directors for their annual Board service. It includes any additional Retainer paid to Committee Chairpersons or the Board Chairperson. **"Base Annual Retainer" means** the Annual Retainer without any additional amounts for Committee Chairpersons, Board Chairpersons or otherwise.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)**"Award"** means, individually or collectively, an award under this Plan of Stock Units.

For purposes of the Plan, an individual whose only employment relationship with the Company is as a Director shall not be deemed to be an Employee.

1

------

**Article 3. Eligibility and Administration**

**1.1Eligibility**. Persons eligible to participate in the Plan are limited to Non-Employee Directors.

**1.2The Committee**. The Plan shall be administered by the Governance and Policy Committee of the Board (the "Committee"), subject to the restrictions set forth in the Plan.

**1.3Administration by the Committee**. The Committee shall have the full power, discretion, and authority to interpret and administer the Plan in a manner consistent with the Plan's provisions. However, in no event shall the Committee have the power to determine Plan eligibility, or to determine the number, the value, the vesting period, or the timing of Awards to be made under the Plan (all such determinations being automatic pursuant to the provisions of the Plan).

**1.4Decisions Binding**. All determinations and decisions made by the Committee pursuant to the Plan, and all related orders or resolutions of the Committee shall be final, conclusive, and binding on all persons, including the Company, its stockholders, Participants, and their estates and beneficiaries.

**Article 4. Shares Previously Acquired Under Plan**

Effective December 31, 2008, no Shares may be issued under this Plan. However, any Shares previously acquired by a Director under this Plan may not be sold for one year after acquisition. Thereafter, such Shares shall only be sold pursuant to an effective registration statement or pursuant to an exemption from the Securities Act of 1933, including sales pursuant to Rule 144 thereunder. The Company may place a legend on the certificates for such Shares evidencing this restriction.

**Article 5. Award of Deferred Stock Units for Non-Employee Directors**

**1.1Award of Deferred Stock Units for Non-Employee Directors**. Effective the day of each annual meeting of the Company's stockholders, beginning with the 2026 annual meeting, each newly-elected or continuing Non-Employee Director shall be granted that number of Stock Units that is equal to $230,000 divided by the Fair Market Value of a Share on the last Trading Day in the calendar month in which such Award is made. Each Award is intended to be in consideration for service until the next annual meeting of stockholders, but will be fully earned on the date of the Award and credited to the Non-Employee Director's account on the day the number of Stock Units is determined. Provided, however, if the Director terminates service on or before the day of the annual meeting of stockholders, the related Award to be earned on such meeting date will not be made.

Effective, June 1, 2021, a Non-Employee Director who is first elected to the Board on a day other than the day of the annual meeting of stockholders, shall be granted a pro-rated number of Stock Units based on the number of days served prior to the next annual meeting (using the

2

------

methodology and initial value formula set forth above and an assumed next annual meeting date one year following the last annual meeting). Such award is intended to be in consideration for

3

------

service until the next annual meeting of stockholders, but will be fully earned on the date of the award.

**1.2Deferral of Retainers into Stock Units**. Each Non-Employee Director may elect to defer all (100%) or fifty percent (50%) of the Director's Annual Retainer paid during the relevant calendar year into Stock Units. The number of Stock Units acquired shall equal the portion of the Annual Retainer being deferred into Stock Units in a calendar month, divided by the Fair Market Value of a Share on the last Trading Day in such calendar month, and such Stock Units shall be credited to the Non-Employee Director's account effective the day the number of Stock Units is determined. Amounts are deferred at the time they otherwise would have been paid were it not for the relevant deferral election.

Any deferral election under this Section 5.2 shall be made prior to the beginning of, and will be effective for, the calendar year in which such payments would be made; provided, however, any newly elected Director shall have thirty (30) days after being elected to the Board to make such elections and may elect to defer all (100%) or fifty percent (50%) of any of the Director's Annual Retainers (including any pro-rated amounts) paid during the calendar year in which the Director is elected to the Board into Stock Units, as permitted by Section 409A of the Internal Revenue Code of 1986. Unless the Non- Employee Director notifies the Secretary of the Company otherwise prior to the beginning of each subsequent calendar year, each election hereunder will renew automatically for an additional calendar year.

**1.3Payout of Deferred Stock Units**. Each Stock Unit shall be paid out in cash equal to the Fair Market Value of a Share; a fractional Share Unit shall be entitled to cash equal to the equivalent fraction of a Share.

The Participant shall elect the timing of the payout for Stock Unit Awards no later than the last day of the calendar year prior to the first scheduled payment of such Stock Units. Notwithstanding the foregoing:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)persons who become Directors after November 19, 2004, shall elect the timing of the payout of their Stock Units (their "Post 2004 Stock Units") no later than the time they first make a deferral election into Stock Units or thirty (30) days after their original election to the Board, whichever is sooner (the Corporate Governance and Nominating Committee may extend only the 30 day deadline and may do so only so long as such extension is permitted by Section 409A of the Internal Revenue Code of 1986, as amended ("Section 409A")); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)each Participant in the Plan as of November 19, 2004 who has not irrevocably elected the timing of the payout of Stock Units shall make such an election by December 31, 2004 with respect to all Stock Units from deferrals of Awards made or Annual Retainer or fees earned after December 31, 2004 (also known as "Post 2004 Stock Units").

One election will apply to all Post 2004 Stock Units, whether from deferrals, annual Awards or otherwise, and Stock Units earned thereon (each such payout schedule is hereinafter referred to as a "Stock Unit Schedule"); and a separate election shall apply to all other Stock Units and earnings

4

------

thereon. Stock Units acquired under this Plan shall, with respect to each Stock Unit Schedule (if more than one), be paid out in a lump sum payment or in up to three (3) annual installments, as elected by the Participant. The lump sum payment or the first installment, as the case may be, for each Stock Unit Schedule shall be payable on the first Business Day of February of the year following the calendar year of the termination of the Participant's service as a Director. Each subsequent annual installment shall be payable on the first Business Day of February. If the Director fails to make a timely election as to the number of installments for any Stock Unit Schedule, such Stock Units shall be paid out in a lump sum.

For Participants electing a payout (or payouts, as the case may be) of Stock Units in installments, the number of Stock Units to be paid out for each Stock Unit Schedule in each installment shall equal the number of Stock Units available for payout under such Stock Unit Schedule, divided by the number of remaining installments (including the installment being made).

**1.4Stock Units**. Each Stock Unit shall represent an unfunded and unsecured promise by the Company to issue cash equal in value to the Stock Unit. Participants holding Stock Units (or fractions thereof) shall earn dividend equivalents paid in the form of additional Stock Units added to their account. The number of Stock Units so added shall equal the dividend on a Share multiplied by the number of Stock Units held by the Participant on the record date for such dividend, divided by the Fair Market Value of a Share on the last Trading Day in the calendar month in which the record date for such dividend occurs. The Stock Units shall be credited to a Participant's account on the day the number of Stock Units is determined.

**Article 6. Cash Deferral Account**

**1.1Cash Deferral Account**. A cash deferral account (the "Cash Deferral Account") shall be established and maintained by the Company for each Participant that makes a cash deferral election under the Plan. Each Cash Deferral Account shall be credited as of the date the amount deferred otherwise would have become due and payable to the Participant and shall be credited to reflect the interest return thereon until paid. The establishment and maintenance of such Cash Deferral Accounts, however, shall not be construed as entitling any Participant to any specific assets of the Company and shall represent an unfunded and unsecured promise of the Company with respect to the amounts due thereunder.

**1.2Cash Deferral Elections**. Effective for payments on or after January 1, 1998, each Non- Employee Director may elect to defer all (100%) or fifty percent (50%) of the Director's Annual Retainer paid during the relevant calendar year into the Director's Cash Deferral Account. Amounts are deferred at the time they otherwise would have been paid were it not for the relevant deferral election.

Any deferral election under this Section 6.2 shall be made prior to the beginning of, and will be effective for, the calendar year in which such payments would be made; provided, however, any newly elected Director shall have thirty (30) days after being elected to the Board to make such elections and may elect to defer all (100%) or fifty percent (50%) of any of the Director's Annual Retainers (including any pro-rated amounts) paid during the calendar year in

5

------

which the Director is elected to the Board into the Director's Cash Deferral Account, as permitted by Section 409A of the Internal Revenue Code of 1986. Unless the Non- Employee Director notifies the Secretary of the Company otherwise prior to the beginning of each subsequent calendar year, each election hereunder will renew automatically for an additional calendar year.

Deferral elections under the Plan made prior to November 21, 1997, shall be credited to the Cash Deferral Account and continue to earn interest in accordance with Section 6.3.

**1.3Interest on Cash Deferral Accounts**. The annual rate of interest on amounts in the Cash Deferral Accounts for 1997 and subsequent calendar years shall be Moody's Long-Term Corporate Bond Yield Average as published by Moody's Investor Service, Inc. (or any successor thereto) for the month of September before the calendar year in question (if such yield is no longer published,a substantially similar average selected by the Committee) or such other rate as the Committee shall determine prior to the year for which the interest rate would be applicable. Such interest shall be compounded quarterly, in arrears, on all unpaid amounts and shall be recorded on Participant's statements quarterly.

**1.4Form and Timing of Payout of Cash Deferral Accounts**. Cash Deferral Accounts shall be paid out in cash. The Participant shall elect the timing of the payout for the Participant's Cash Deferral Account no later than the last day of the calendar year prior to the first scheduled payment thereof. Notwithstanding the foregoing:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)persons who become Directors after November 19, 2004, shall elect the timing of the payout of their Cash Deferral Account (their "Post 2004 CDA Deferrals") no later than the time they first make a deferral election into their Cash Deferral Account;

One election shall apply to a Participant's Post 2004 CDA Deferrals and earnings thereon (each such payout schedule is hereinafter referred to as a "Cash Account Schedule"); and a separate election shall apply to amounts that are not Post 2004 CDA Deferrals and earnings thereon.

A Participant's Cash Deferral Account shall, with respect to each Cash Account Schedule (if more than one), be paid out in a lump sum payment or in up to three (3) annual installments, as elected by the Participant. The lump sum payment or the first installment, as the case may be, for each Cash Account Schedule shall be payable on the first Business Day of February of the year following the calendar year of the termination of the Participant's service as a Director. Each subsequent annual installment shall be payable on the first Business Day of February. If the Director fails to make a timely election as to the number of installments for any Cash Account Schedule, the Participant's Cash Deferral Account shall be paid out in a lump sum. Each installment shall equal the amount available for payout under such Cash Account Schedule, divided by the number of remaining installments (including the installment being made).

**1.5Conversion of Non-Employee Director's Cash Deferral Account to Deferred Stock Units**. Each year, on or before the close of trading in Shares on the NYSE on the tenth day (if the tenth day is not a Trading Day, then the next preceding Trading Day) following the Company's public release of its annual summary statement of earnings (typically in January of each year)

6

------

(such Trading Day to be the "Conversion Date"), a Non-Employee Director may elect to convert all or part of the balance of his or her Cash Deferral Account into Stock Units. Notwithstanding the foregoing, however, no such conversion of Post 2004 CDA Deferrals shall be permitted unless the payout schedules for such Participant's Post 2004 CDA Deferrals and Post 2004 Stock Units are identical. Each such election shall become irrevocable as of the last time such election may be made. A Non-Employee Director who elects to convert his or her Cash Deferral Account shall receive the number of Stock Units found by dividing the Non-Employee Director's balance in the Cash Deferral Account, together with all accrued but not yet credited interest, or such lesser amount of the Cash Deferral Account elected by the Non-Employee Director, by the Fair Market

Value of a Share on the Conversion Date. Upon such conversion, the Participant's Cash Deferral Account shall be reduced by the amount so converted.

**Article 7. Amendment, Modification, and Termination**

**1.1Amendment, Modification, and Termination**. Subject to the terms set forth in this Article 7, the Board may terminate, amend, or modify the Plan at any time and from time to time.

**1.2Awards Previously Granted**. Unless required by law, no termination, amendment, or modification of the Plan shall in any material manner adversely affect any Award previously provided under the Plan, without the written consent of the Participant holding the Award.

**Article 8. Miscellaneous**

**1.1Elections**. All elections and notices of any kind hereunder shall be in writing and provided to the Secretary of the Company in a form prescribed by the Secretary. Unless marked as irrevocable, an election may be modified or revoked at any time prior to, and shall not be effective until, the deadline for making such election.

**1.2Assignment**. Except as otherwise expressly provided herein, no rights under this Plan may be assigned by a Participant.

**1.3Savings Clause.** In the event any provision of the Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provision had not been included. Notwithstanding any provision to the contrary in this Plan, each provision in this Plan shall be interpreted to permit the deferral of compensation in accordance with Section 409A of the Internal Revenue Code of 1986, as amended, and any provision that would conflict with such requirements shall not be valid or enforceable.

**1.4Death of a Director/Beneficiary Designation**. Each Participant under the Plan may, from time to time, name any beneficiary or beneficiaries (who may be named primarily or contingently) to whom any benefit under the Plan is to be paid in the event of his or her death. Each designation will revoke all prior designations by the same Participant, shall be in a form prescribed by the Secretary of the Company, and will be effective only when provided by the Participant in writing to the Secretary during such Participant's lifetime. In the absence of any

7

------

such designation, benefits remaining unpaid at the Participant's death shall be paid to the Participant's estate.

In the event of the death of a Participant before full payment of all amounts due hereunder, the balance shall be paid in a lump sum as soon as administratively possible in accordance with the foregoing. Notwithstanding this, if the Participant so elects as part of the Participant's deferral elections, the Stock Units and/or the Cash Deferral Account will be paid out in the number of annual installments elected by the Participant, beginning on the first Business Day of February following the calendar year of the Participant's death and occurring annually thereafter; provided, however, if distributions to the Participant have already commenced at the time of the Participant's death, then under this election, distributions will continue as scheduled.

8

------

**1.5No Right of Nomination**. Nothing in the Plan shall be deemed to create any obligation on the part of the Board to nominate any Director for reelection by the Company's stockholders.

**1.6Successors**. All obligations of the Company under the Plan with respect to Awards granted hereunder shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company.

**1.7Requirements of Law**. The granting of Awards under the Plan shall be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required.

**1.8Governing Law**. The Plan and all agreements hereunder, shall be construed in accordance with and governed by the internal, substantive laws of the State of Texas.

**1.9Adjustments.** In the event of a merger, reorganization, consolidation, recapitalization, separation, liquidation, stock dividend, stock split, share combination, or other change in the corporate structure of the Company affecting the Shares, such adjustment shall be made in the number of outstanding Stock Units as may be determined to be appropriate and equitable by the Board, in its sole discretion, to prevent dilution or enlargement of rights.
