UNDERWRITING AGREEMENT

April 23, 2026

To the Representative(s)

named in Schedule I

hereto

of the Underwriters

named in Schedule II hereto

Ladies and Gentlemen:

AT&T Inc., a Delaware

corporation (the “Company”), may issue and sell from time to time series of its debt securities registered under the registration statement referred to in Paragraph 1(a) hereof (“Securities” and, individually,

“Security”). The Securities will be issued under an Indenture, dated as of May 15, 2013 (the “Indenture”), from the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee, in one or more series, which

series may vary as to interest rates, maturities, redemption provisions and selling prices, with all such terms for any particular series being determined at the time of sale. The Company proposes to sell to the underwriters named in Schedule II

hereto (“Underwriters”), for whom you are acting as representative(s) (“Representative”), the series of Securities of the designation, with the terms and in the aggregate principal amount specified in Schedule I hereto

(“Underwritten Securities” and, individually, “Underwritten Security”).

1. The Company represents and warrants

to, and agrees with, the several Underwriters that:

(a) A registration statement on Form

S-3 with respect to the Securities has been prepared by the Company in conformity with the requirements of the Securities Act of 1933, as amended (“Securities Act”), and the rules and regulations

(“Rules and Regulations”) of the Securities and Exchange Commission (“Commission”) thereunder and has become effective. As used in this Agreement:

(i) “Registration Statement” as of any time means the Registration Statement in the form then filed with the

Commission, including any amendment thereto, any document incorporated by reference therein and any information in a prospectus, preliminary prospectus supplement (where applicable) or prospectus supplement deemed or retroactively deemed to be a

part thereof pursuant to Rule 430B that has not been superseded or modified. “Registration Statement” without

reference to a time means the Registration Statement as of the time of the first contract of sale for the Underwritten Securities, which time shall be considered the “effective date”

of the Registration Statement relating to the Underwritten Securities. For purposes of this definition, information contained in a form of prospectus, preliminary prospectus supplement (where applicable) or prospectus supplement that is deemed

retroactively to be a part of the Registration Statement pursuant to Rule 430B shall be considered to be included in the Registration Statement as of the time specified in Rule 430B.

(ii) “Preliminary Prospectus,” when used, means any preliminary prospectus (including any preliminary prospectus

supplement) relating to the Securities filed with the Commission pursuant to Rule 424(b) under the Securities Act.

(iii)

“Statutory Prospectus” as of any time means the prospectus relating to the Underwritten Securities that is included in the Registration Statement immediately prior to that time, including any document incorporated by reference therein

and any basic prospectus or prospectus supplement deemed to be a part thereof pursuant to Rule 430B that has not been superseded or modified. For purposes of this definition, information contained in a form of prospectus (including a prospectus

supplement) that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430B shall be considered to be included in the Statutory Prospectus only as of the actual time that form of prospectus (including a prospectus

supplement) is filed with the Commission pursuant to Rule 424(b).

(iv) “Prospectus” means the Statutory

Prospectus that discloses the public offering price and other final terms of the Underwritten Securities and otherwise satisfies Section 10(a) of the Securities Act.

(v) “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule

433, relating to the Underwritten Securities in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g). “General Use Issuer Free

Writing Prospectus” means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors, as evidenced by its being specified in a schedule to this Agreement. “Limited Use Issuer Free Writing

Prospectus” means any Issuer Free Writing Prospectus that is not a General Use Issuer Free Writing Prospectus.

(vi)

“Applicable Time” means the time and date identified as such in Schedule I of this Agreement.

(b) The

Registration Statement and the Prospectus contain, and (in the case of any amendment or supplement to any such document, or any material incorporated by reference in any such document, filed with the Commission after the date as of which this

representation is being made) will contain at all times during the period specified in

-2-

Paragraph 9(c) hereof, all statements which are required by the Securities Act, the Securities Exchange Act of 1934, as amended (“Exchange Act”), the Trust Indenture Act of 1939, as

amended (“Trust Indenture Act”), and the rules and regulations of the Commission under such Acts; the Indenture, including any amendments and supplements thereto, pursuant to which the Underwritten Securities will be issued will conform

with the requirements of the Trust Indenture Act and the rules and regulations of the Commission thereunder; and the Registration Statement, the General Disclosure Package (as defined herein) and the Prospectus do not, and (in the case of any

amendment or supplement to any such document, or any material incorporated by reference in any such document, filed with the Commission after the date as of which this representation is being made) will not at any time during the period specified in

Paragraph 9(c) hereof, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading except that the Company makes no representation or

warranty as to information contained in or omitted from the Registration Statement, the General Disclosure Package (as defined herein) or the Prospectus in reliance upon and in conformity with information furnished in writing to the Company through

the Representatives by or on behalf of any Underwriter specifically for use therein, or as to any statements in or omissions from the Statement of Eligibility and Qualification of the Trustee under the Trust Indenture Act.

(c)

(i) (A) At the time of initial filing of the Registration Statement, (B) at the time of the most recent amendment thereto

for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), and

(C) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Underwritten Securities in reliance on the exemption of Rule 163, the Company was a

“well known seasoned issuer” as defined in Rule 405, including not having been an “ineligible issuer” as defined in Rule 405.

(ii) The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405, that

initially became effective within three years of the date of this Agreement. If immediately prior to the Renewal Deadline (as hereinafter defined), any of the Underwritten Securities remain unsold by the Underwriters, the Company will prior to the

Renewal Deadline file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Underwritten Securities, in a form satisfactory to the Representative. If the Company is no longer eligible

to file an automatic shelf registration statement, the Company will prior to the Renewal Deadline, if it has not already done so, file a new shelf registration statement relating to the Underwritten Securities, in a form satisfactory to the

Representative, and will use its best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline. The Company will take all other action necessary or appropriate to permit the public offering

-3-

and sale of the Underwritten Securities to continue as contemplated in the expired registration statement relating to the Underwritten Securities. References herein to the Registration Statement

shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be. “Renewal Deadline” means the third anniversary of the initial effective time of the Registration Statement.

(iii) The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to use of the automatic shelf

registration statement form. If at any time when Underwritten Securities remain unsold by the Underwriters the Company receives from the Commission a notice pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf

registration statement form, the Company will (i) promptly notify the Representative, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Underwritten Securities, in a form

satisfactory to the Representative, (iii) use its best efforts to cause such registration statement or post-effective amendment to be declared effective as soon as practicable, and (iv) promptly notify the Representative of such

effectiveness. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Underwritten Securities to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2)

notice or for which the Company has otherwise become ineligible. References herein to the Registration Statement shall include, or refer to, as applicable, such new registration statement or post-effective amendment, as the case may be.

(iv) The Company has paid or shall pay the required Commission filing fees relating to the Underwritten Securities within the time required by

Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

(d) (i) At

the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2)) of the Underwritten Securities and (ii) at the date of this

Agreement, the Company was not and is not an “ineligible issuer,” as defined in Rule 405.

(e) As of the

Applicable Time, neither (i) the General Use Issuer Free Writing Prospectus(es) issued at or prior to the Applicable Time, the Statutory Prospectus, any Preliminary Prospectus (where applicable) and the additional information, if any,

identified in Schedule I to this Agreement, all considered together (collectively, the “General Disclosure Package”), nor (ii) any individual Limited Use Issuer Free Writing Prospectus, when considered together with the General

Disclosure Package, included any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading except that

the Company makes no representation or warranty as to information contained in or omitted from any prospectus included in the Registration Statement or any Issuer Free Writing Prospectus in reliance upon and in conformity with

-4-

information furnished in writing to the Company through the Representative by or on behalf of any Underwriter specifically for use therein.

(f) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public

offer and sale of the Underwritten Securities or until any earlier date that the Company notified or notifies the Representative as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or

will conflict with the information then contained in the Registration Statement. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing

Prospectus conflicted or would conflict with the information then contained in the Registration Statement or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to

make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, (i) the Company has promptly notified or will promptly notify the Representative and (ii) the Company has promptly amended

or will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(g) The Company is not in violation of its corporate charter or bylaws or in default under any agreement, indenture or

instrument, the effect of which violation or default would be material to the Company; the execution, delivery and performance of this Agreement and any Delayed Delivery Contracts (as defined in Paragraph 3 hereof) and compliance by the Company with

the provisions of the Underwritten Securities and the Indenture will not conflict with, result in the creation or imposition of any lien, charge or encumbrance upon any of the assets of the Company or any of its material subsidiaries pursuant to the

terms of, or constitute a default under, any agreement, indenture or instrument, or result in a violation of the corporate charter or bylaws of the Company or any order, rule or regulation of any court or governmental agency having jurisdiction over

the Company; and except as required by the Securities Act, the Trust Indenture Act and applicable state securities laws, no consent, authorization or order of, or filing or registration with, any court or governmental agency is required for the

execution, delivery and performance of this Agreement, the Delayed Delivery Contracts, if any, and the Indenture. The Commission has not issued any order preventing or suspending the use of any part of the Registration Statement, any Preliminary

2. Subject to the terms and conditions and in reliance upon the representations and

warranties herein set forth, the Company agrees to sell to each Underwriter, and each Underwriter, severally and not jointly, agrees to purchase from the Company, at the purchase price and on the other terms set forth in Schedule I hereto, the

principal amount of the Underwritten Securities set forth opposite its name in Schedule II hereto. The Underwriters shall reimburse the Company in the aggregate for up to $4,650,000 of the Company’s expenses, each Underwriter to be responsible

Underwritten Securities set forth therein to be purchased by all of the Underwriters (in each case as adjusted by the Representative to avoid fractions of the minimum principal amount in which

the Underwritten Securities may be issued), except to the extent that the Representative determines, in its discretion, that such deduction shall be otherwise than in such proportion and so advises the Company.

6. The Company shall not be obligated to deliver any Underwritten Securities except upon

payment for all Immediate Delivery Underwritten Securities to be purchased pursuant to this Agreement as hereinafter provided.

Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Immediate Delivery Underwritten Securities which

the defaulting Underwriter agreed but failed to purchase in the respective proportions which the principal amount of Underwritten Securities set forth in Schedule II hereto to be purchased by each remaining

If the foregoing maximums are

exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representative who so agree, shall have the right, but shall not be obligated, to purchase, in such

proportion as may be agreed upon among them, all the Immediate Delivery Underwritten Securities. If the remaining Underwriters or other underwriters satisfactory to the Representative do not elect to purchase the Immediate Delivery Underwritten

Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, or the Company, except

that the Company will continue to be liable for the payment of expenses as set forth in Paragraph 9(h) hereof.

Nothing contained in this

Paragraph 7 shall relieve a defaulting Underwriter of any liability it may have to the Company for damages caused by its default. If other Underwriters are obligated or agree to purchase the Immediate Delivery Underwritten Securities of a defaulting

Registration Statement, the General Disclosure Package, the Prospectus or in any other document or arrangement.

8. Delivery of and payment

for the Immediate Delivery Underwritten Securities shall be made at such address, date and time as may be specified in Schedule I hereto. This date and time are sometimes referred to as the “Delivery Date.” On the Delivery Date, the

Company shall deliver the Immediate Delivery Underwritten Securities to the Representative for the account of each Underwriter against payment to or upon the order of the Company of the purchase price by certified or official bank check or checks or

wire transfer payable in Federal (same day) funds. Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder. Upon delivery, the

Immediate Delivery Underwritten Securities shall be in such form or forms and in such denominations as may be set forth in Schedule I. Immediate Delivery Underwritten Securities in registered form shall be in such authorized denominations and

registered in such names as the Representative shall request in writing not less than two full

-10-

business days prior to the Delivery Date. For the purpose of expediting the checking and packaging of the Immediate Delivery Underwritten Securities, the Company shall make the Immediate Delivery

Underwritten Securities available for inspection by the Representative in New York, New York not later than 2:00 P.M., local time, on the business day prior to the Delivery Date.

9. The Company agrees with the several Underwriters that:

(a) The Company will furnish promptly to the Representative and to counsel for the Underwriters signed copies of the

Registration Statement as originally filed and each amendment and supplement thereto filed prior to the date hereof and relating to or covering the Underwritten Securities, and a copy of the Prospectus filed with the Commission, including all

documents incorporated therein by reference and all consents and exhibits filed therewith;

(b) The Company will deliver

promptly to the Representative such reasonable number of the following documents as the Representative may request: (i) conformed copies of the Registration Statement (excluding exhibits other than the computation of the ratio of earnings to

fixed charges, the Indenture and this Agreement), (ii) the Prospectus, (iii) any Issuer Free Writing Prospectus and (iv) any documents incorporated by reference in the Prospectus or any Issuer Free Writing Prospectus;

(c) During any period when a prospectus relating to the Underwritten Securities is (or, but for the exemption in Rule 172,

would be) required by law to be delivered, the Company will not file any amendment of the Registration Statement nor will the Company file any amendment or supplement to the Prospectus (except for (i) an amendment or supplement consisting

solely of the filing of a document under the Exchange Act or (ii) a supplement relating to an offering of securities other than the Underwritten Securities), unless the Company has furnished the Representative with a copy of such proposed

amendment or supplement for its review prior to filing and will not file any such proposed amendment or supplement to which the Representative reasonably objects. Subject to the foregoing sentence, the Company will cause each Statutory Prospectus

(including the Prospectus), each Preliminary Prospectus (where applicable) and any amendment or supplement thereto to be filed with the Commission as required pursuant to Rule 424 under the Securities Act not later than the second business day

following the earlier of the date it is first used or the date of this Agreement. The Company will promptly advise the Representative (i) when each Statutory Prospectus, each Preliminary Prospectus (where applicable) or any amendment or

supplement thereto shall have been filed with the Commission pursuant to Rule 424 under the Securities Act, (ii) when any amendment of the Registration Statement shall have become effective, (iii) of any request by the Commission for any

amendment of the Registration Statement or amendment of or supplement to any Statutory Prospectus, Preliminary Prospectus (where applicable) or Issuer Free Writing Prospectus or for any additional information, (iv) of the issuance by the

Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose or under Section 8A of the Securities Act and (v) of the receipt by the Company of

any notification with respect to the suspension of the qualification of the Underwritten

-11-

Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose. The Company will promptly (upon filing thereof) furnish the Representative a copy of

any amendment or supplement to any Statutory Prospectus, Issuer Free Writing Prospectus or Registration Statement not furnished to the Representative for prior review pursuant to exception (i) or (ii) of the first sentence of this subsection

(c). The Company will use its best efforts to prevent the issuance of any such stop order and, if issued, to obtain as soon as possible the withdrawal thereof;

(d) If, at any time when a prospectus relating to the Underwritten Securities is (or, but for the exemption in Rule 172, would

be) required to be delivered under the Securities Act, any event occurs as a result of which the Registration Statement, as then amended, or the Prospectus, as then amended or supplemented, would include any untrue statement of a material fact or

omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it shall be necessary to amend the Registration Statement or to amend or supplement the

Prospectus to comply with the Securities Act or the Exchange Act or the respective rules thereunder, the Company promptly will (i) notify the Representative of the happening of such event, (ii) prepare and file with the Commission, subject

to the first sentence of paragraph (c) of this Paragraph 9, an amendment or supplement which will correct such statement or omission or an amendment or supplement which will effect such compliance and (iii) will supply any such amended or

supplemented Prospectus to the Representative in such quantities as the Representative may reasonably request;

(e) As soon

as practicable, the Company will make generally available to its security holders and to the Representative an earnings statement or statements of the Company which will satisfy the provisions of Section 11(a) of the Securities Act and Rule 158

under the Securities Act;

(f) During a period of five years after the date hereof, the Company will furnish to the

Representative copies of all reports and financial statements furnished by the Company to each securities exchange on which securities issued by the Company may be listed pursuant to requirements of or agreements with such exchange or to the

Commission pursuant to the Exchange Act or any rule or regulation of the Commission thereunder; provided, however, that the Company will be deemed to have furnished such reports and financial statements to the Representative to the extent they are

available through the Commission’s Electronic Data Gathering, Analysis and Retrieval system or any successor system;

(g) The Company will endeavor to qualify the Underwritten Securities for sale under the laws of such jurisdictions as the

Representative may designate and will maintain such qualifications in effect so long as required for the distribution of the Underwritten Securities, provided that in connection therewith the Company shall not be required to qualify as a foreign

corporation or take any action which would subject it to general or unlimited service of process in any jurisdiction where it is not now so subject;

(h) The Company will pay the costs incident to the authorization, issuance and delivery of the Underwritten Securities and any

taxes payable in that connection; the

-12-

costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement and any amendments, supplements and exhibits thereto; the costs of distributing the

Registration Statement as originally filed and each amendment and post-effective amendment thereof (including exhibits), any Statutory Prospectus, any Preliminary Prospectus (where applicable), the Prospectus and any documents incorporated by

reference in any of the foregoing documents; the costs incident to the preparation, printing and distribution of each Issuer Free Writing Prospectus to investors or prospective investors; the costs of producing this Agreement, the Delayed Delivery

Contracts, if any, and the Indenture; fees paid to rating agencies in connection with the rating of the Securities, including the Underwritten Securities; the fees and expenses of qualifying the Underwritten Securities under the securities laws of

the several jurisdictions as provided in this Paragraph and of preparing and printing a Blue Sky Memorandum and a memorandum concerning the legality of the Securities, including the Underwritten Securities, as an investment (including fees of

counsel to the Underwriters); and all other costs and expenses incident to the performance of the Company’s obligations under this Agreement; provided that, except as provided in this Paragraph and in Paragraph 13 hereof, the Underwriters

shall pay their own costs and expenses, including the fees and expenses of their counsel, any transfer taxes on the Underwritten Securities which they may sell and the expenses of advertising any offering of the Underwritten Securities made by the

Underwriters;

(i) Until the termination of the offering of the Underwritten Securities, the Company will timely file all

documents, and any amendments to previously filed documents, required to be filed by the Company pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act;

(j) During the period beginning on the date hereof and continuing to the Delivery Date, the Company will not offer, sell,

contract to sell or otherwise dispose of any senior debt securities of the Company or any guarantees or support obligations of debt securities of others, in any case with maturities longer than one year, other than Underwritten Securities to the

Underwriters and as otherwise disclosed in the Prospectus; provided, however, that this Paragraph 9(j) shall apply only to U.S. dollar-denominated senior debt securities of the Company;

(k) The Company represents and agrees that, unless it obtains the prior consent of the Representative, and each Underwriter

represents and agrees that, unless it obtains the prior consent of the Company and the Representative, it has not made and will not make any offer relating to the Underwritten Securities that would constitute an Issuer Free Writing Prospectus, or

that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Representative is hereinafter referred to

as a “Permitted Free Writing Prospectus.” The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has

complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping. The Company has complied and will comply with

Rule 433; and

-13-

(l) The Company has prepared a final term sheet, which is attached hereto as

Schedule IV, relating to the Underwritten Securities, containing only information that describes the final terms of the Underwritten Securities and otherwise in a form consented to by the Representative, and will file such final term sheet within

the period required by Rule 433(d)(5)(ii) following the date such final terms have been established for all classes of the offering of the Underwritten Securities. Any such final term sheet is an Issuer Free Writing Prospectus and a Permitted Free

Writing Prospectus for purposes of this Agreement. The Company also consents to the use by any Underwriter of a free writing prospectus only in the form of one or more term sheets relating to the Underwritten Securities and containing customary

information, it being understood that any such free writing prospectus referred to above shall not be an Issuer Free Writing Prospectus for purposes of this Agreement.

10. (a) The Company shall indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the

meaning of the Securities Act from and against any loss, claim, damage or liability, joint or several, and any action in respect thereof, to which that Underwriter or controlling person may become subject, under the Securities Act or otherwise,

insofar as such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement at any time, any Statutory Prospectus at any time,

any Preliminary Prospectus (where applicable), the Prospectus or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or arises out of, or is based

upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse each Underwriter and such controlling person for any legal and

other expenses reasonably incurred by that Underwriter or controlling person in investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred (but no more frequently than

annually); provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or

alleged omission made in the Registration Statement at any time, any Statutory Prospectus at any time, any Preliminary Prospectus (where applicable), the Prospectus or any Issuer Free Writing Prospectus in reliance upon and in conformity with

written information furnished to the Company through the Representative by or on behalf of any Underwriter specifically for use therein. The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any

Underwriter or controlling person.

(b) Each Underwriter shall indemnify and hold harmless the Company, each of their

directors, each of their officers who signed the Registration Statement and any person who controls the Company within the meaning of the Securities Act from and against any loss, claim, damage or liability, joint or several, and any action in

respect thereof, to which the Company, or any such director, officer or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, any

untrue statement or alleged untrue statement of a material fact contained in the Registration Statement at any time, any Statutory Prospectus at any time, any Preliminary Prospectus (where applicable), the Prospectus or any Issuer Free Writing

Prospectus, or arises out of, or is based upon, the

-14-

omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that

the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with information furnished in writing to the Company through the Representative by or on behalf of that Underwriter

specifically for use therein, and shall reimburse the Company for any legal and other expenses reasonably incurred by the Company or any such director, officer or controlling person in investigating or defending or preparing to defend against any

such loss, claim, damage, liability or action as such expenses are incurred (but no more frequently than annually). The foregoing indemnity agreement is in addition to any liability which any Underwriter may otherwise have to the Company or any of

its directors, officers or controlling persons.

(c) Promptly after receipt by an indemnified party under this Paragraph 10

of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Paragraph 10, notify the indemnifying party in writing of the claim or

the commencement of that action, provided that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under Paragraph 10(a) or (b). If any such claim or action

shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein, and, to the extent that it wishes, jointly with any other similarly notified

indemnifying party, to assume the defense thereof with counsel satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying

party shall not be liable to the indemnified party under this Paragraph 10 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation. If the

indemnifying party shall not elect to assume the defense of such action, such indemnifying party will reimburse such indemnified party for the reasonable fees and expenses of any counsel retained by them. In the event that the parties to any such

action (including impleaded parties) include both the Company and one or more Underwriters and either (i) the indemnifying party or parties and indemnified party or parties mutually agree or (ii) representation of both the indemnifying

party or parties and the indemnified party or parties by the same counsel is inappropriate under applicable standards of professional conduct or in the opinion of such counsel due to actual or potential differing interests between them, then the

indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party and will reimburse such indemnified party for the reasonable fees and expenses of any counsel retained by them and satisfactory to

the indemnifying party, it being understood that the indemnifying party shall not, in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be

liable for the reasonable fees and expenses of more than one separate firm of attorneys for all such indemnified parties, which firm shall be designated in writing by the Representative in the case of an action in which one or more Underwriters or

controlling persons are indemnified parties and by the Company in the case of an action in which the Company or any of its directors, officers or controlling persons are

-15-

indemnified parties. The indemnifying party or parties shall not be liable under this Agreement with respect to any settlement made by any indemnified party or parties without prior written

consent by the indemnifying party or parties to such settlement.

(d) If the indemnification provided for in this Paragraph

10 shall for any reason be unavailable to an indemnified party under Paragraph 10(a) or 10(b) hereof in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in

lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, in such proportion as is appropriate to reflect the

relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Underwritten Securities. If, however, this allocation is not permitted by applicable law, then each indemnifying party

shall contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, in such proportion as shall be appropriate to reflect the relative benefits received by the

Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Underwritten Securities and the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, with respect to the statements or

omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the

other hand, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Underwritten Securities (before deducting expenses) received by the Company bear to the total underwriting

discounts and commissions received by the Underwriters with respect to such offering. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a

material fact relates to information supplied by the Company or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or

payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Paragraph 10(d) shall be deemed to include, for purposes of this Paragraph 10(d), any legal or other

expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Paragraph 10(d), no Underwriter shall be required to contribute any amount in

excess of the amount by which the total price at which the Underwritten Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise paid or become

liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution

from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Paragraph 10(d) are several in proportion to their respective underwriting obligations and not joint.

-16-

(e) The agreements contained in this Paragraph 10 and the representations,

warranties and agreements of the Company in Paragraph 1 and Paragraph 9 hereof shall survive the delivery of the Underwritten Securities and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or

any investigation made by or on behalf of any indemnified party.

11. The obligations of the Underwriters under this Agreement may be

terminated by the Representative, in its absolute discretion, by notice given to and received by the Company prior to the delivery of and payment for the Immediate Delivery Underwritten Securities, if, on or after the Applicable Time,

(a) trading in securities generally on the New York Stock Exchange, Inc. is suspended or materially limited, or (b) a banking moratorium is declared by either Federal or New York State authorities, or (c) there shall have occurred any

outbreak or material escalation of hostilities or other calamity or crisis or the declaration by the United States of war or a national emergency the effect of which on the financial markets of the United States is material and adverse and is such

as to make it, in the reasonable judgment of the Representative, impracticable or inadvisable to market such Underwritten Securities on the terms and in the manner contemplated by the General Disclosure Package, or (d) the Company shall have

received notice that any rating of any of the Company’s unsecured senior debt securities, guarantees or support obligations shall have been lowered by any nationally recognized statistical rating organization (as defined in

Section 3(a)(62) of the Exchange Act) or any such organization has publicly announced that it has under surveillance or review, with possible negative implications, the ratings of any of the Company’s unsecured senior debt securities,

guarantees or support obligations, or (e) there shall have occurred any change, or any development involving a prospective change, in or affecting particularly the business or properties of the Company or its subsidiaries which, in the

Representative’s reasonable judgment, materially impairs the investment quality of the Underwritten Securities.

12. The respective

obligations of the Underwriters under this Agreement with respect to the Underwritten Securities are subject to the accuracy, on the date hereof and on the Delivery Date, of the representations and warranties of the Company contained herein, to

performance by the Company of its obligations hereunder, and to each of the following additional terms and conditions applicable to the Underwritten Securities:

(a) At or before the Delivery Date, no stop order suspending the effectiveness of the Registration Statement nor any order

directed to any document incorporated by reference in any Preliminary Prospectus (where applicable), the Prospectus or any Issuer Free Writing Prospectus shall have been issued, and prior to that time no stop order proceeding shall have been

initiated or threatened by the Commission and no challenge shall have been made by the Commission or its staff as to the accuracy or adequacy of any document incorporated by reference in any Preliminary Prospectus (where applicable), the Prospectus

or any Issuer Free Writing Prospectus; any request of the Commission for inclusion of additional information in the Registration Statement or any Statutory Prospectus or otherwise shall have been complied with; and after the date hereof the Company

shall not have filed with the Commission any amendment or supplement to the Registration Statement, any Statutory Prospectus, the Prospectus or any Issuer Free Writing Prospectus (or, in each case, any document incorporated by reference therein)

that shall have been disapproved by the Representative.

-17-

(b) No Underwriter shall have discovered and disclosed to the Company on or

prior to the Delivery Date that the Registration Statement, the General Disclosure Package, the Prospectus, or any Issuer Free Writing Prospectus contains an untrue statement of a fact which is material or omits to state a fact which is material and

is required to be stated therein or is necessary to make the statements therein not misleading.

(c) All corporate

proceedings and other legal matters incident to the authorization, form and validity of this Agreement, the Underwritten Securities and the Indenture and the form of the Registration Statement, the Prospectus (other than financial statements and

other financial data) and all other legal matters relating to this Agreement and the transactions contemplated hereby shall be satisfactory in all respects to Sullivan & Cromwell LLP, counsel for the Underwriters, and the Company shall have

furnished to such counsel all documents and information that they may reasonably request to enable them to pass upon such matters.

(d) Any of the (x) Senior Executive Vice President and General Counsel, (y) Senior Vice President, Secretary and

Chief Privacy Officer or (z) Assistant Vice President – Senior Legal Counsel and Assistant Secretary to the Company shall have furnished to the Representative his or her opinion addressed to the Underwriters and dated the Delivery Date,

as counsel, to the effect that:

(i) the Company has been duly incorporated and is validly existing as a corporation in

good standing under the laws of the State of Delaware; each material subsidiary of the Company has been duly incorporated and is validly existing as a corporation or limited liability company, as applicable, in good standing under the laws of the

jurisdiction in which it is chartered or organized; and each of the Company and its material subsidiaries has full corporate power and authority to own its properties and conduct its business as described in the General Disclosure Package, and is

duly qualified to do business as a foreign corporation and is in good standing under the laws of each jurisdiction which requires such qualification wherein it owns or leases properties or conducts business, except where the failure to so qualify

would not have a material adverse effect on the Company and its subsidiaries taken as a whole;

(ii) the Indenture has been

duly authorized, executed and delivered, has been duly qualified under the Trust Indenture Act, and constitutes a legal, valid and binding instrument enforceable against the Company in accordance with its terms (subject, as to enforcement of

remedies, to applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws of general applicability relating to or affecting creditors’ rights generally from time to time in effect and to general

principles of equity);

(iii) to the best knowledge of such counsel, there is no pending or threatened action, suit or

proceeding before any court or governmental agency, authority, body or any arbitrator involving the Company or any of its subsidiaries of a character required to be disclosed in the Registration Statement which is not

-18-

adequately disclosed in the General Disclosure Package, and there is no franchise, contract or other document of a character required to be described in the Registration Statement or the General

Disclosure Package, or to be filed as an exhibit, which is not described or filed as required; and the statements included or incorporated by reference in the General Disclosure Package describing any legal proceedings or material contracts or

agreements relating to the Company or any of its subsidiaries fairly summarize such matters; the Underwritten Securities, the Indenture and any Delayed Delivery Contracts conform to the descriptions thereof contained under the following (or

comparable) captions of the Prospectus: “Description of Debt Securities We May Offer” and “Plan of Distribution”;

(iv) the Immediate Delivery Underwritten Securities have been duly authorized and executed, and, when authenticated by the

Trustee and delivered by the Company to the Underwriters against payment therefor in accordance with the terms of this Agreement, will constitute valid and binding obligations of the Company entitled to the benefits of the Indenture and will be

enforceable against the Company in accordance with their terms;

(v) the Delayed Delivery Underwritten Securities, if any,

have been duly authorized and, when executed, authenticated, issued and delivered to, and paid for by, the respective purchasers thereof in accordance with the Indenture and the related Delayed Delivery Contracts, will be valid and legally binding

obligations of the Company entitled to the benefits of the Indenture;

(vi) the Registration Statement and any amendments

thereto have become effective under the Securities Act; to the best knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued, no proceedings for that purpose have been instituted or

threatened, and the Registration Statement, the Prospectus and each amendment thereof or supplement thereto as of their respective effective or issue dates (other than the financial statements and other financial and statistical information

contained therein or incorporated by reference therein and the Statement of Eligibility and Qualification of the Trustee on Form T-1 as to which such counsel need express no opinion) complied as to form in all

material respects with the applicable requirements of the Securities Act, the Exchange Act and the Trust Indenture Act and the respective rules and regulations thereunder;

(vii) such counsel has no reason to believe that the Registration Statement, or any amendment thereof, at the effective date

established by the Prospectus pursuant to Rule 430B(f), at the date of this Agreement or at the Delivery Date, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make

the statements therein not misleading; such counsel has no reason to believe that the documents specified in a schedule to such counsel’s letter, consisting of those included in the General Disclosure Package, as of the Applicable Time or at

the Delivery Date, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make

-19-

the statements therein, in the light of the circumstances under which they were made, not misleading; and such counsel has no reason to believe that the Prospectus, at the date of this Agreement

or at the Delivery Date, included or includes any untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading

(other than the financial statements and other financial and statistical information contained therein or incorporated by reference therein and the Statement of Eligibility and Qualification of the Trustee on Form

T-1);

(viii) this Agreement and the Delayed Delivery Contracts, if any, have been

duly authorized, executed and delivered by the Company;

(ix) no order, consent, approval, authorization, registration or

qualification of or with any governmental agency or body having jurisdiction over the Company or any of its properties is required under the Included Laws for the issue and sale of the Underwritten Securities or the consummation by the Company of

the transactions contemplated by this Agreement or the Indenture, except such as have been obtained under the Securities Act and the Trust Indenture Act and such consents, approvals, authorizations, registrations or qualifications as may be required

under state securities or Blue Sky laws in connection with the sale and distribution of the Underwritten Securities. The term “Included Laws” means: (i) the laws of the State of New York, (ii) the Delaware General Corporation

Law, and (iii) the Federal securities laws of the United States of America that are, in counsel’s experience, normally applicable to transactions of the type contemplated in this Agreement. The term “Included Laws” excludes

(a) laws of any counties, cities, towns, municipalities and special political subdivisions and agencies thereof; (b) state securities laws or Blue Sky laws; (c) the laws that apply to the Underwriters because of their legal or

regulatory status, including the rules and regulations of the Financial Industry Regulatory Authority Inc.; and (d) laws relating to land use, zoning and building code issues, taxes, environmental issues, intellectual property issues and

antitrust issues; and

(x) neither the execution and delivery of the Indenture, this Agreement or any Delayed Delivery

Contracts, the issue and sale of the Underwritten Securities, nor the consummation of any other of the transactions herein or therein contemplated nor the fulfillment of the terms hereof or thereof will conflict with, result in a breach of, or

constitute a default under, the charter or by-laws of the Company or the terms of any indenture or other agreement or instrument known to such counsel and to which the Company or any of its material

subsidiaries is a party or by which the Company, any such subsidiary or any of their assets is bound, or any order or regulation governed by Included Laws known to such counsel to be applicable to the Company or any such subsidiary of any court,

regulatory body, administrative agency, governmental body or arbitrator having jurisdiction over the Company or any such subsidiary.

-20-

In rendering such opinion, such counsel may rely, as to the execution of the Indenture by

the Trustee, upon a certificate of the Trustee setting forth the facts as to such execution.

In rendering such opinion, such counsel may

also rely (A) as to matters involving the application of laws of any jurisdiction other than the State of Delaware, upon the opinion of other counsel of good standing believed to be reliable, provided that such counsel states in such opinion

that such counsel and the Representative are justified in relying upon the opinion of such other counsel, and (B) as to matters or fact, to the extent deemed proper, on certificates of responsible officers of the Company and public officials.

In rendering such opinion with respect to clause (ix) above, insofar as it relates to regulatory authorities in the states in which

the Company or any material subsidiary operates, such counsel may rely on the opinions of local counsel satisfactory to such counsel.

(e) The Representative shall have received from Sullivan & Cromwell LLP, counsel for the Underwriters, such opinion or

opinions, dated the Delivery Date, with respect to the issuance and sale of the Underwritten Securities, the Indenture, the Registration Statement, the General Disclosure Package, the Prospectus and other related matters as the Representative may

reasonably require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(f) The Company shall have furnished to the Representative a certificate signed by its Chairman of the Board, its President, a

Senior Vice President, its Treasurer or an Assistant Treasurer stating that after reasonable investigation and to the best of their knowledge:

(i) the representations and warranties of the Company in this Agreement are true and correct in all material respects on and as

of the Delivery Date with the same effect as if made on the Delivery Date; the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied as a condition to the obligation of the

Underwriters to purchase the Underwritten Securities hereunder; and the conditions set forth in Paragraphs 12(a) and 12(h) have been fulfilled;

(ii) as of the Applicable Time and as of the Delivery Date, the Registration Statement and the General Disclosure Package did

not include any untrue statement of a material fact and did not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and

(iii) except as may have been publicly disclosed prior to the date of this Agreement, since the date of the most recent

financial statements included or incorporated by reference in the General Disclosure Package, there has been no material adverse change in the condition (financial or other), earnings, business or properties of the Company and its subsidiaries,

taken as a whole, whether or not

-21-

arising from transactions in the ordinary course of business, except as set forth in or contemplated in the General Disclosure Package.

(g) (i) The Company shall have furnished to the Representative letters of Ernst & Young LLP, addressed to the Board of

Directors of the Company and the Underwriters and dated the date of this Agreement and the Delivery Date, respectively, of the type described in the Public Company Accounting Oversight Board Guidance AS Section 6101 (“AS 6101”) with

respect to the Company and (ii) the Representative shall have received a letter, dated the Delivery Date and addressed to the Representative, of any other independent auditor whose report is included or incorporated by reference in the

Registration Statement of the type described in AS 6101, and in each of (i) and (ii), covering such financial statement items as counsel for the Underwriters may reasonably have requested.

(h) No order, consent, approval, authorization, registration or qualification of or with any governmental agency or body having

jurisdiction over the Company or any of its properties is required for the issue and sale of the Underwritten Securities or the consummation by the Company of the transactions contemplated by this Agreement or the Indenture, except such as have

been, or will have been prior to the Delivery Date, obtained under the Securities Act and the Trust Indenture Act and such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or Blue Sky

laws in connection with the purchase and distribution of the Underwritten Securities by the Underwriters.

All opinions, letters, evidence

and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance satisfactory to the Representative.

13. If the Company shall fail to tender the Immediate Delivery Underwritten Securities for delivery to the Underwriters for any reason

permitted under this Agreement, or if the Underwriters shall decline to purchase the Immediate Delivery Underwritten Securities for any reason permitted under this Agreement (other than pursuant to Paragraph 7 or Paragraphs 11(a)-(d) hereof),

the Company shall reimburse the Underwriters for the reasonable fees and expenses of their counsel and for such other out-of-pocket expenses as shall have been incurred

by them in connection with this Agreement and the proposed purchase of Immediate Delivery Underwritten Securities and the solicitation of any purchases of the Delayed Delivery Underwritten Securities, and upon demand the Company shall pay the full

amount thereof to the Representative. If this Agreement is terminated pursuant to Paragraph 7 hereof by reason of the default of one or more Underwriters or pursuant to Paragraph 11(a)-(d) hereof, the Company shall not be obligated to reimburse any

Underwriter on account of those expenses.

14. The Company shall be entitled to act and rely upon any request, consent, notice or agreement

by, or on behalf of, the Representative. Any notice by the Company to the Underwriters shall be sufficient if given in writing or by facsimile transmission confirmed promptly in writing addressed to the Representative at its address set forth in

Schedule I hereto, and any notice by the Underwriters to the Company shall be sufficient if given in writing or by facsimile transmission confirmed promptly in writing addressed to the Company at AT&T Inc.,

-I-2-

certain changes in the tax laws, at a redemption price equal to 100% of the principal amount of the 2033 Notes to be redeemed together with interest accrued thereon to, but excluding, the date fixed for redemption.

Investment Banker appointed by the Company.

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term (assuming

Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury

-I-3-

Dealer at 3:30 p.m., New York City time, on the third business day preceding such redemption date.

“Reference Treasury Dealer” means each of BofA Securities, Inc., Deutsche Bank Securities Inc., Morgan Stanley & Co. LLC, MUFG Securities Americas Inc., TD Securities (USA) LLC, Wells Fargo Securities, LLC and

their respective affiliates and, at the option of the Company, one other nationally recognized investment banking firm that is a primary U.S. Government Securities dealer in the United States (each, a “Primary Treasury Dealer”);

provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer.

“Remaining Scheduled Payments” means, with respect to each 2033 Note to be redeemed, the remaining scheduled payments of principal of and interest on such 2033 Notes that would be due after the related redemption date

through February 28, 2033 assuming the 2033 Notes matured on February 28, 2033 (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 2033 Notes, the amount of the next succeeding scheduled interest payment on the 2033 Notes will be reduced by the amount of interest accrued on the 2033 Notes to the redemption date.

On and after the redemption date, interest will cease to accrue on the 2033 Notes or any portion of the 2033 Notes called for redemption, unless the Company defaults in the payment of the redemption price and accrued interest. On or

before the redemption date, the Company will deposit with the Company’s paying agent or the Trustee money sufficient to pay the redemption price of and accrued interest on the 2033 Notes to be redeemed on that date. Any redemption or notice

may, at the Company’s discretion, be subject to one or more conditions precedent and, at the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions precedent included at the Company’s

discretion shall be satisfied (or waived by the Company) or the redemption date may not occur and such notice may be rescinded if all such conditions precedent included at the Company’s discretion

shall

-I-4-

not have been satisfied (or waived by the Company). In the case of any partial redemption, selection of the 2033 Notes to be redeemed, will be made in accordance with applicable procedures of the Depository Trust Company.

Form and Authorized Denominations:

Cede & Co., as nominee for The Depository Trust Company.

Delivery Date, Time and Location:

the delivery of and payment for the 2033 Notes, if, during the period beginning on the date of the Agreement to and including the Delivery Date, there shall have occurred any outbreak or material escalation of hostilities or other calamity or crisis

or the declaration by the United States of war or a national emergency or any change in national or international financial, political or economic conditions or currency exchange rates or exchange controls the effect of which on the financial

markets is material and adverse and is such as to make it, in the reasonable judgment of the Representatives, impracticable or inadvisable to market such 2033 Notes on the terms and in the manner contemplated by the Prospectus.

semiannually in arrears on April 30 and October 30 in each year, commencing on October 30, 2026 (each an “Interest Payment Date”) and on the Maturity Date, at the interest rate of 4.750% per annum, until the principal

the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The Notes will be issued in fully registered form only and in minimum denominations of $2,000 and integral multiples of $1,000

outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes at the time outstanding to waive compliance by AT&T with certain provisions of the Indenture and certain past

defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of

transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

No

Optional Redemption by AT&T

The Notes may be redeemed at any time prior to February 28, 2033, as a whole or in part, at AT&T’s option, at any time and from

time to time on at least 5 days’, but not more than 40 days’, prior notice mailed (or otherwise transmitted in accordance with DTC procedures) to the registered address of each holder of the Notes to be redeemed. The redemption price

will be calculated by AT&T 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 a semiannual basis (assuming a 360-day year consisting of twelve 30-day months), at a rate equal to the sum of the Treasury Rate (as defined below)

plus 15 basis points. 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 February 28, 2033, the Notes may be redeemed, as a whole or in

part, at AT&T’s option, at any time and from time to time on at least 5 days’, but not more than 40 days’, prior notice mailed (or otherwise transmitted in accordance with DTC procedures) to the registered address of each

holder of the Notes to be redeemed, 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, but excluding, the redemption date. AT&T will calculate the redemption

price in connection with any redemption hereunder.

“Treasury Rate” means, with respect to any redemption date for the Notes,

the rate per annum equal to the semiannual equivalent yield to maturity or interpolation (on a day count basis) of the interpolated Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its

principal amount) equal to the Comparable Treasury Price for such redemption date, as determined by AT&T or an Independent Investment Banker appointed by AT&T.

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker

as having an actual or interpolated maturity comparable to the remaining term (assuming that the Notes matured on February 28, 2033), of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary

financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of the Notes (assuming that the Notes matured on February 28, 2033).

“Independent Investment Banker” means one of the Reference Treasury Dealers, appointed by AT&T.

“Comparable Treasury Price” means, with respect to any redemption date for the Notes, (1) the average of the Reference

Treasury Dealer Quotations for such redemption date after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if AT&T obtains fewer than three such Reference Treasury Dealer Quotations, the average of all

such quotations.

2

“Reference Treasury Dealer Quotations” means, with respect to each Reference

Treasury Dealer and any redemption date for the Notes, the average, as determined by AT&T, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to

AT&T by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such redemption date.

“Reference Treasury Dealer” means BofA Securities, Inc., Deutsche Bank Securities Inc., Morgan Stanley & Co. LLC, MUFG

Securities Americas Inc., TD Securities (USA) LLC, Wells Fargo Securities, LLC and their respective affiliates and, at the option of AT&T, one other nationally recognized investment banking firm that is a primary U.S. Government Securities

dealer in the United States (each, a “Primary Treasury Dealer”); provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, AT&T will substitute therefor another Primary Treasury Dealer.

“Remaining Scheduled Payments” means, with respect to each Note to be redeemed, the remaining scheduled payments of principal of

and interest on such Notes that would be due after the related redemption date through February 28, 2033, assuming the Notes matured on February 28, 2033 (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 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 AT&T defaults in the payment of the redemption price and accrued interest. On or before the redemption date, AT&T will deposit with its 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 AT&T’s discretion, be subject to one or more

conditions precedent and, at AT&T’s discretion, the redemption date may be delayed until such time as any or all such conditions precedent included at AT&T’s discretion shall be satisfied (or waived by AT&T) or the redemption

date may not occur and such notice may be rescinded if all such conditions precedent included at AT&T’s discretion shall not have been satisfied (or waived by AT&T).

AT&T will, subject to the exceptions and limitations set forth below, pay as additional interest on this Note such additional amounts

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

this Note had no withholding or deduction been

3

voting power of all classes of stock of AT&T entitled to vote;

(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;

(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;

4

(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;

(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;

(6) to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar

tax, assessment or governmental charge;

(7) to any tax, assessment or other governmental charge any paying agent (which

term may include AT&T) 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

(8) in the case of any combination of the above items.

In addition, any amounts to be paid on this Note 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 section entitled “Payment of Additional Amounts” and under the heading “Redemption Upon a Tax Event”, AT&T shall 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.

5

Redemption Upon a Tax Event

If (a) AT&T becomes or will become obligated to pay 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 January 29, 2026 or (b) a taxing authority of the United States takes an action on or after January 29, 2026, whether or not with

respect to AT&T or any of its affiliates, that results in a substantial probability that AT&T will or may be required to pay such Additional Amounts, then AT&T may, at its 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 AT&T 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 AT&T will or may be

required to pay the Additional Amounts and AT&T shall have delivered to the Trustee a certificate, signed by a duly authorized officer, stating that based on such opinion, AT&T is entitled to redeem the Notes pursuant to their terms.

Further Issues

AT&T

reserves the right from time to time, without notice to or the consent of the Holders of the Notes, to 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, 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 the board of directors of AT&T, a supplement to the Indenture, or under an officers’ certificate pursuant to the Indenture.

Notes in Definitive Form

with the Indenture, or (2) the Depository is at any time unwilling or unable to continue as depository and a successor depository is not appointed by AT&T within 90 days, AT&T may issue notes in definitive form in exchange for this

Note. In either instance, an owner of a beneficial interest in the Notes will be entitled to the physical delivery in definitive form in exchange for this Note, equal in principal amount to such beneficial interest and to have such Notes registered

in its name.

Notes so issued in definitive form will be issued as registered notes in minimum denominations of $2,000 and integral

multiples of $1,000 thereafter, unless otherwise specified by AT&T.

charge that may be imposed in connection with any exchange or registration of transfer of definitive Notes.

Default

Dollars ($500,000,000) on October 30, 2036 (the “Maturity Date”), and to pay interest on said principal sum from April 30, 2026 or from the most recent Interest Payment Date to which interest has been paid or duly provided for,

semiannually in arrears on April 30 and October 30 in each year, commencing on October 30, 2026 (each an “Interest Payment Date”) and on the Maturity Date, at the interest rate of 5.250% per annum, until the principal

hereof is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Note (or one or more

predecessor Notes) is registered at the close of business on the Regular Record Date for such interest, which shall be the close of business on the fifteenth day preceding the respective Interest

Payment Date (each, a “Regular Record Date”). Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name

principal or any interest on this Note that remains unclaimed for two years after the date upon which the principal and interest are due and payable, will be repaid to AT&T upon AT&T’s 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 this Note will be able to seek any payment to which such Holder may be entitled to

collect only from AT&T.

If the Notes are issued in definitive form, payment of the principal and interest on this Note due at the

Maturity Date or upon redemption will be made at the Maturity Date or upon redemption, as the case may be, upon presentation of this Note, in immediately available funds, at the office of The Bank of New York Mellon Trust Company, N.A., the Paying

and Transfer Agent and Registrar for the Notes, currently located at 601 Travis Street, 16th Floor, Houston, Texas 77002.

Payment of

interest on this Note due on an Interest Payment Date, other than interest at maturity or upon redemption, may be paid by check mailed to the address of the Holder entitled thereto as such address shall appear in the Note register. Notwithstanding

the foregoing, (1) the Depository as Holder of the Notes or (2) a Holder of more than U.S.$5,000,000 in aggregate principal amount of Notes in definitive form is entitled to require the Paying Agent to make payments of interest, other than

instructions not less than ten days prior to the applicable Interest Payment Date.

Reference is hereby made to the further provisions

of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual or electronic

indenture and all indentures supplemental thereto (collectively, the “Indenture”) reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, AT&T and

the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The Notes will be issued in fully registered form only and in minimum denominations of $2,000 and integral multiples of $1,000

thereafter. This Note is one of the series designated on the face hereof initially limited in aggregate principal amount to $1,750,000,000.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations

of AT&T and the rights of the Holders of the Notes under the Indenture at any time by AT&T and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time outstanding. The Indenture also contains

provisions permitting the Holders of specified percentages in principal amount of the Notes at the time outstanding to waive compliance by AT&T with certain provisions of the Indenture and certain past defaults under the Indenture and their

consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or

in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

No reference herein to the Indenture and no

provision of this Note or of the Indenture shall alter or impair the obligation of AT&T, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency, herein

Registrar and Paying Agent

AT&T shall maintain in the Borough of Manhattan, The City of New York, an office or agency where Notes may be surrendered for registration

of transfer or exchange (“Registrar”) and an office or agency where Notes may be presented for payment or for exchange (“Paying Agent”). AT&T has initially appointed the Trustee, The Bank of New York Mellon Trust

Company, N.A., as its Registrar and Paying Agent. AT&T may vary or terminate the appointment of any of its paying or transfer agencies, and may appoint additional paying or transfer agencies.

Optional Redemption by AT&T

The Notes may be redeemed at any time prior to July 30, 2036, as a whole or in part, at AT&T’s option, at any time and from time

to time on at least 5 days’, but not more than 40 days’, prior notice mailed (or otherwise transmitted in accordance with DTC procedures) to the registered address of each holder of the Notes to be redeemed. The redemption price will be

calculated by AT&T 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 a semiannual basis (assuming a 360-day year consisting of twelve 30-day months), at a rate equal to the sum of the Treasury Rate (as defined below) plus 15

basis points. 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 July 30, 2036, the Notes may be redeemed, as a whole or in part, at

AT&T’s option, at any time and from time to time on at least 5 days’, but not more than 40 days’, prior notice mailed (or otherwise transmitted in accordance with DTC procedures) to the registered address of each holder of the

Notes to be redeemed, 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, but excluding, the redemption date. AT&T will calculate the redemption price in

connection with any redemption hereunder.

“Treasury Rate” means, with respect to any redemption date for the Notes, the rate

per annum equal to the semiannual equivalent yield to maturity or interpolation (on a day count basis) of the interpolated Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal

amount) equal to the Comparable Treasury Price for such redemption date, as determined by AT&T or an Independent Investment Banker appointed by AT&T.

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker

as having an actual or interpolated maturity comparable to the remaining term (assuming that the Notes matured on July 30, 2036), of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary

financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of the Notes (assuming that the Notes matured on July 30, 2036).

“Independent Investment Banker” means one of the Reference Treasury Dealers, appointed by AT&T.

“Comparable Treasury Price” means, with respect to any redemption date for the Notes, (1) the average of the Reference

Treasury Dealer Quotations for such redemption date after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if AT&T obtains fewer than three such Reference Treasury Dealer Quotations, the average of all

such quotations.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any

redemption date for the Notes, the average, as determined by AT&T, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to AT&T by such Reference

Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such redemption date.

2

“Reference Treasury Dealer” means J.P. Morgan Securities LLC, Mizuho Securities

USA LLC, Santander US Capital Markets LLC, Societe Generale, New York Branch, SMBC Nikko Securities America, Inc., and their respective affiliates and, at the option of AT&T, one other nationally recognized investment banking firm that is a

primary U.S. Government Securities dealer in the United States (each, a “Primary Treasury Dealer”); provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, AT&T will substitute therefor another

Primary Treasury Dealer.

“Remaining Scheduled Payments” means, with respect to each Note to be redeemed, the

remaining scheduled payments of principal of and interest on such Notes that would be due after the related redemption date through July 30, 2036, assuming the Notes matured on July 30, 2036 (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 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 AT&T defaults in the payment of the redemption price and accrued interest. On or before the redemption date, AT&T will deposit with its 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 AT&T’s

discretion, be subject to one or more conditions precedent and, at AT&T’s discretion, the redemption date may be delayed until such time as any or all such conditions precedent included at AT&T’s discretion shall be satisfied (or

waived by AT&T) or the redemption date may not occur and such notice may be rescinded if all such conditions precedent included at AT&T’s discretion shall not have been satisfied (or waived by AT&T).

In the case of any partial redemption, selection of the Notes to be redeemed will be made in accordance with applicable procedures of DTC.

Payment of Additional Amounts

AT&T will, subject to the exceptions and limitations set forth below, pay as additional interest on this Note such additional amounts

(“Additional Amounts”) as are necessary so that the net payment by AT&T or its Paying Agent of the principal of and interest on this Note 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

this Note 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.

3

The foregoing obligation to pay Additional Amounts shall not apply:

(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:

(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;

(b) is or was a citizen or resident or is or was treated as a resident of the United States;

(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;

(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

(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;

(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;

(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;

4

(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;

(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;

(6) to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar

tax, assessment or governmental charge;

(7) to any tax, assessment or other governmental charge any paying agent (which

term may include AT&T) 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

(8) in the case of any combination of the above items.

In addition, any amounts to be paid on this Note 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 section entitled “Payment of Additional Amounts” and under the heading “Redemption Upon a Tax Event”, AT&T shall 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) AT&T becomes or will become obligated to pay 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 April 23, 2026 or (b) a taxing authority of the United States takes an action on or after April 23, 2026, whether or not with

respect to AT&T or any of its affiliates, that results in a substantial probability that AT&T will or may be required to pay such Additional

5

Amounts, then AT&T may, at its 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 AT&T 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 AT&T will or may be required to pay the Additional Amounts and AT&T shall have delivered to the Trustee a

certificate, signed by a duly authorized officer, stating that based on such opinion, AT&T is entitled to redeem the Notes pursuant to their terms.

Further Issues

AT&T

reserves the right from time to time, without notice to or the consent of the Holders of the Notes, to 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, 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 the board of directors of AT&T, a supplement to the Indenture, or under an officers’ certificate pursuant to the Indenture.

Notes in Definitive Form

with the Indenture, or (2) the Depository is at any time unwilling or unable to continue as depository and a successor depository is not appointed by AT&T within 90 days, AT&T may issue notes in definitive form in exchange for this

Note. In either instance, an owner of a beneficial interest in the Notes will be entitled to the physical delivery in definitive form in exchange for this Note, equal in principal amount to such beneficial interest and to have such Notes registered

in its name.

Notes so issued in definitive form will be issued as registered notes in minimum denominations of $2,000 and integral

multiples of $1,000 thereafter, unless otherwise specified by AT&T.

Notes so issued in definitive form may be transferred by

presentation for registration to the Registrar at its New York office and must be duly endorsed by the Holder or the Holder’s attorney duly authorized in writing, or accompanied by a written instrument or instruments of transfer in form

satisfactory to AT&T or the Trustee duly executed by the Holder or his attorney duly authorized in writing.

AT&T may require

payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any exchange or registration of transfer of definitive Notes.

6

Default

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal hereof may be declared, and upon

such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

Miscellaneous

purposes of the Notes, a Business Day means a business day in The City of New York.

No director, officer, employee or stockholder, as

such, of AT&T shall have any liability for any obligations of AT&T under this Note, the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting this Note waives and

releases all such liability. The waiver and release are part of the consideration for the issue of this Note.

The Notes are the unsecured

and unsubordinated obligations of AT&T and will rank pari passu with all other evidences of indebtedness issued in accordance with the Indenture.

Dollars ($500,000,000) on October 30, 2066 (the “Maturity Date”), and to pay interest on said principal sum from April 30, 2026 or from the most recent Interest Payment Date to which interest has been paid or duly provided for,

semiannually in arrears on April 30 and October 30 in each year, commencing on October 30, 2026 (each an “Interest Payment Date”) and on the Maturity Date, at the interest rate of 6.300% per annum, until the principal

This Note is one of a duly authorized issue of debt securities of AT&T of the series specified on the face hereof, issued under and

indenture and all indentures supplemental thereto (collectively, the “Indenture”) reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, AT&T and

the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The Notes will be issued in fully registered form only and in minimum denominations of $2,000 and integral multiples of $1,000

thereafter. This Note is one of the series designated on the face hereof initially limited in aggregate principal amount to $1,000,000,000.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations

of AT&T and the rights of the Holders of the Notes under the Indenture at any time by AT&T and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time outstanding. The Indenture also contains

provisions permitting the Holders of specified percentages in principal amount of the Notes at the time outstanding to waive compliance by AT&T with certain provisions of the Indenture and certain past defaults under the Indenture and their

consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or

in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

No reference herein to the Indenture and no

provision of this Note or of the Indenture shall alter or impair the obligation of AT&T, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency, herein

prescribed.

Registrar and Paying Agent

AT&T shall maintain in the Borough of Manhattan, The City of New York, an office or agency where Notes may be surrendered for registration

of transfer or exchange (“Registrar”) and an office or agency where Notes may be presented for payment or for exchange (“Paying Agent”). AT&T has initially appointed the Trustee, The Bank of New York Mellon Trust

Company, N.A., as its Registrar and Paying Agent. AT&T may vary or terminate the appointment of any of its paying or transfer agencies, and may appoint additional paying or transfer agencies.

Optional Redemption by AT&T

The Notes may be redeemed at any time prior to April 30, 2066, as a whole or in part, at AT&T’s option, at any time and from

time to time on at least 5 days’, but not more than 40 days’, prior notice mailed (or otherwise transmitted in accordance with DTC procedures) to the registered address of each holder of the Notes to be redeemed. The redemption price

will be calculated by AT&T 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 a semiannual basis (assuming a 360-day year consisting of twelve 30-day months), at a rate equal to the sum of the Treasury Rate (as defined below)

plus 25 basis points. 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 April 30, 2066, the Notes may be redeemed, as a whole or in part,

at AT&T’s option, at any time and from time to time on at least 5 days’, but not more than 40 days’, prior notice mailed (or otherwise transmitted in accordance with DTC procedures) to the registered address of each holder of

the Notes to be redeemed, 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, but excluding, the redemption date. AT&T will calculate the redemption price in

connection with any redemption hereunder.

“Treasury Rate” means, with respect to any redemption date for the Notes, the rate

per annum equal to the semiannual equivalent yield to maturity or interpolation (on a day count basis) of the interpolated Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal

amount) equal to the Comparable Treasury Price for such redemption date, as determined by AT&T or an Independent Investment Banker appointed by AT&T.

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker

as having an actual or interpolated maturity comparable to the remaining term (assuming that the Notes matured on April 30, 2066), of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary

financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of the Notes (assuming that the Notes matured on April 30, 2066).

“Independent Investment Banker” means one of the Reference Treasury Dealers, appointed by AT&T.

“Comparable Treasury Price” means, with respect to any redemption date for the Notes, (1) the average of the Reference

Treasury Dealer Quotations for such redemption date after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if AT&T obtains fewer than three such Reference Treasury Dealer Quotations, the average of all

such quotations.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any

redemption date for the Notes, the average, as determined by AT&T, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to AT&T by such Reference

Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such redemption date.

2

“Reference Treasury Dealer” means J.P. Morgan Securities LLC, Mizuho Securities

USA LLC, Santander US Capital Markets LLC, Societe Generale, New York Branch, SMBC Nikko Securities America, Inc., and their respective affiliates and, at the option of AT&T, one other nationally recognized investment banking firm that is a

primary U.S. Government Securities dealer in the United States (each, a “Primary Treasury Dealer”); provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, AT&T will substitute therefor another

Primary Treasury Dealer.

“Remaining Scheduled Payments” means, with respect to each Note to be redeemed, the

remaining scheduled payments of principal of and interest on such Notes that would be due after the related redemption date through April 30, 2066, assuming the Notes matured on April 30, 2066 (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 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 AT&T defaults in the payment of the redemption price and accrued interest. On or before the redemption date, AT&T will deposit with its 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 AT&T’s

discretion, be subject to one or more conditions precedent and, at AT&T’s discretion, the redemption date may be delayed until such time as any or all such conditions precedent included at AT&T’s discretion shall be satisfied (or

waived by AT&T) or the redemption date may not occur and such notice may be rescinded if all such conditions precedent included at AT&T’s discretion shall not have been satisfied (or waived by AT&T).

In the case of any partial redemption, selection of the Notes to be redeemed will be made in accordance with applicable procedures of DTC.

Payment of Additional Amounts

AT&T will, subject to the exceptions and limitations set forth below, pay as additional interest on this Note such additional amounts

(“Additional Amounts”) as are necessary so that the net payment by AT&T or its Paying Agent of the principal of and interest on this Note 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

this Note 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.

voting power of all classes of stock of AT&T entitled to vote;

(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;

(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;

4

(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;

(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;

(6) to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar

tax, assessment or governmental charge;

(7) to any tax, assessment or other governmental charge any paying agent (which

term may include AT&T) 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

(8) in the case of any combination of the above items.

In addition, any amounts to be paid on this Note 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 section entitled “Payment of Additional Amounts” and under the heading “Redemption Upon a Tax Event”, AT&T shall 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.

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

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 AT&T 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 AT&T will or may be required to pay the Additional Amounts

and AT&T shall have delivered to the Trustee a certificate, signed by a duly authorized officer, stating that based on such opinion, AT&T is entitled to redeem the Notes pursuant to their terms.
