Ladies and Gentlemen:

Introductory. Equifax Inc., a Georgia corporation (the “Company”), proposes, subject to the terms and conditions stated herein, to issue and sell to the several underwriters named in Schedule A hereto (the “Underwriters”), acting severally and not jointly, the respective amounts set forth in such Schedule A of $650,000,000 aggregate principal amount of the Company’s 4.800% Senior Notes due 2029 (the “Securities”). BofA Securities, Inc., J.P. Morgan Securities LLC, Mizuho Securities USA LLC and Wells Fargo Securities, LLC, have agreed to act as representatives of the several Underwriters (in such capacity, the “Representatives”) in connection with the offering and sale of the Securities.

The Securities will be issued pursuant to, and will form a separate series of senior debt securities under, the indenture, dated as of May 12, 2016 (the “Base Indenture”), between the Company and U.S. Bank Trust Company, National Association (successor in interest to U.S. Bank National Association), as indenture trustee (the “Trustee”). Certain terms of the Securities will be established pursuant to a supplemental indenture (the “Supplemental Indenture”) to the Base Indenture (together with the Base Indenture, the “Indenture”). The Securities will be issued in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”).

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-266290), which contains a base prospectus (the “Base Prospectus”), to be used in connection with the public offering and sale of senior debt securities, including the Securities, of the Company under the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations promulgated thereunder (the “Securities Act Regulations”), and the offering thereof from time to time in accordance with Rule 415 under the Securities Act. Such registration statement, including the financial statements, exhibits and schedules thereto, in the form in which it became effective under the Securities Act, including any required information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430B under the Securities Act, is called the

“Registration Statement.” The term “Prospectus” shall mean the final prospectus supplement relating to the Securities, together with the Base Prospectus, that is first filed pursuant to Rule 424(b) after the date and time that this Agreement is executed (the “Execution Time”) by the parties hereto. The term “Preliminary Prospectus” shall mean any preliminary prospectus supplement relating to the Securities, together with the Base Prospectus, that is first filed with the Commission pursuant to Rule 424(b). Any reference herein to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents that are or are deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act prior to 1:50 p.m. on August 12, 2024 (the “Initial Sale Time”). All references in this Agreement to the Registration Statement, the Preliminary Prospectus, the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included,” “described,” or “stated” in the Registration Statement, the Prospectus or the Preliminary Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which are or are deemed to be incorporated by reference in the Registration Statement, the Prospectus or the Preliminary Prospectus, as the case may be, prior to the Initial Sale Time; and all references in this Agreement to amendments or supplements to the Registration Statement, the Prospectus or the Preliminary Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder (collectively, the “Exchange Act”), which is incorporated or deemed to be incorporated by reference in the Registration Statement, the Prospectus or the Preliminary Prospectus, as the case may be, after the Initial Sale Time.

The Company hereby confirms its agreements with the Underwriters as follows:

SECTION 1. Representations and Warranties. The Company hereby represents, warrants and covenants to each Underwriter as of the date hereof, as of the Initial Sale Time and as of the Closing Date (in each case, a “Representation Date”) and agrees with each of the Underwriters as follows:

(a) Compliance with Registration Requirements. The Company meets the requirements for use of Form S-3 under the Securities Act. The Registration Statement has become effective under the Securities Act and no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are threatened by the Commission, and any request on the part of the Commission for additional information has been complied with. In addition, the Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, and the rules and regulations promulgated thereunder (the “Trust Indenture Act”).

At the respective times the Registration Statement and any post-effective amendments thereto became effective and at each Representation Date, the Registration Statement and any amendments thereto (i) complied and will comply in all material respects with the requirements of the Securities Act and the Trust Indenture Act, and (ii) did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that, with respect to clause (ii) hereof, the Company makes no representations or warranties as to those parts of the Registration Statement which shall constitute Statements of Eligibility and Qualification on Form T-1 (the “Form T-1”) under the Trust Indenture Act. At the date of the Prospectus and at the Closing Date, neither the Prospectus nor any amendments or supplements thereto included or will include an untrue statement of a material fact or omitted or will omit to state a material fact

2

necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, the representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement or any post-effective amendment or the Prospectus or any amendments or supplements thereto made in reliance upon and in conformity with information furnished to the Company in writing by any of the Underwriters through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 8(b) hereof.

The Preliminary Prospectus and the Prospectus, at the time each was filed with the Commission, complied in all material respects with the Securities Act, and the Preliminary Prospectus and the Prospectus delivered to the Underwriters for use in connection with the offering of the Securities will, at the time of such delivery, be identical to any electronically transmitted copies thereof filed with the Commission through EDGAR, except to the extent permitted by Regulation S-T.

(b) Disclosure Package. The term “Disclosure Package” shall mean (i) the Preliminary Prospectus dated August 12, 2024, (ii) the issuer free writing prospectuses as defined in Rule 433 of the Securities Act (each an “Issuer Free Writing Prospectus”), if any, identified in Annex I hereto and (iii) any other free writing prospectus that the parties hereto shall hereafter expressly agree in writing to treat as part of the Disclosure Package and identified in Annex II hereto. As of the Initial Sale Time, the Disclosure Package did not contain any untrue statement of a material fact or omit 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. The preceding sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 8(b) hereof.

(c) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus (collectively, the “Incorporated Documents”) (i) at the time they were or hereafter are filed with the Commission complied and will comply, as the case may be, as of their respective dates of filing, in all material respects with the requirements of the Exchange Act and the rules and regulations of the Commission thereunder (the “Exchange Act Regulations”) and (ii) when read together with the other information in the Disclosure Package, at the Initial Sale Time, and when read together with the other information in the Prospectus, at the date of the Prospectus and at the Closing Date, did not or will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) Company is a Well-Known Seasoned Issuer. (i) At the time of filing the Registration Statement, (ii) 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), (iii) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) of the Securities Act) made any offer relating to the Securities in reliance on the exemption of Rule 163 of the Securities Act, and (iv) as of the Execution Time, the Company was and is a “well known seasoned issuer” as defined in Rule 405 of the Securities Act. The Registration Statement is an “automatic shelf registration statement,” as

Each “employee pension benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401 of the Code is so qualified and the Company is not aware of any circumstances likely to cause the loss of such qualification.

(hh) IT Systems and Data Compliance. (i) (x) Except as described or incorporated by reference in each of the Disclosure Package and the Prospectus the Company is not aware of any material security breach or other compromise of or relating to any of the information technology and computer systems, networks, websites, applications, hardware, software, data (including the data of customers, employees, suppliers, vendors and any other third party data), equipment or technology (collectively, “IT Systems and Data”) used in the Company’s and its subsidiaries’ business and (y) the Company and its subsidiaries have not been notified of, and have no knowledge of, any event or condition that would reasonably be expected to result in, any material security breach or other compromise to their IT Systems and Data; (ii) the Company and its subsidiaries are presently in compliance with all applicable laws or statutes and all judgments, orders, rules and regulations of any court or arbitrator or governmental or regulatory authority relating to the privacy and security of IT Systems and Data and to the protection of such IT Systems and Data from unauthorized use, access, misappropriation or modification; and (iii) the Company and its subsidiaries believe they have implemented commercially reasonable privacy policies and security, backup and disaster recovery technology for all IT Systems and Data used in its business, including with respect to enabling the Company to fulfill relevant applicable contractual obligations, except as such would not, in the case of clause (ii) above, individually or in the aggregate, have a Material Adverse Effect.

Any certificate signed by an officer of the Company and delivered to the Representatives or to counsel for the Underwriters shall be deemed to be a representation and warranty by the Company to each Underwriter as to the matters set forth therein.

SECTION 2. Purchase, Sale and Delivery of the Securities.

On the basis of the representations, warranties and agreements herein contained, and upon the terms but subject to the conditions herein set forth, the Underwriters agree, and each Underwriter, severally and not jointly, agrees to purchase from the Company the aggregate principal amount of Securities set forth in Schedule A opposite the name of such Underwriter, plus any additional principal amount of Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 18 hereof, at a purchase price of 99.368% of the principal amount of the Securities, plus accrued interest, if any, from August 15, 2024 to the Closing Date (as defined below), payable on the Closing Date.

(b) The Closing Date. Delivery of certificates for the Securities in global form to be purchased by the Underwriters and payment of the purchase price therefor shall be made at the offices of Simpson Thacher and Bartlett LLP, 425 Lexington Avenue, New York, New York 10017 (or such other place as may be agreed to by the Company and the Representatives) at 9:00 a.m. New York City time, on August 15, 2024 (unless postponed in accordance with the provisions of Section 18), or such other time and date as the Underwriters shall designate by notice to the Company (the time and date of such closing are called the “Closing Date”).

(c) Public Offering of the Securities. The Representatives hereby advise the Company that the Underwriters intend to offer for sale to the public, as described in the Disclosure Package and the Prospectus, their respective portions of the Securities as soon after the Execution Time as the Representatives, in their sole judgment, have determined is advisable and practicable.

(d) Payment for the Securities. Payment for the Securities shall be made at the Closing Date by wire transfer of immediately available funds to the order of the Company.

It is understood that the Representatives have been authorized, for their own accounts and for the accounts of the several Underwriters, to accept delivery of and receipt for, and make payment of the purchase price for, the Securities that the Underwriters have agreed to purchase. The Representatives may (but shall not be obligated to) make payment for any Securities to be purchased by any Underwriter whose funds shall not have been received by the Representatives by the Closing Date for the account of such Underwriter, but any such payment shall not relieve such Underwriter from any of its obligations under this Agreement.

(e) Delivery of the Securities. The Company shall deliver, or cause to be delivered, to the Representatives for the accounts of the several Underwriters certificates for the Securities at the Closing Date against the irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefor. The certificates for the Securities shall be in such denominations specified by the Representatives in writing at least one business day preceding the Closing Date and registered in the name of Cede & Co., as nominee of the Depositary, and shall be made available for inspection on the business day preceding the Closing Date.

SECTION 3. Additional Covenants. The Company further covenants and agrees with each Underwriter as follows:

(a) Compliance with Securities Regulations and Commission Requests. The Company, subject to Section 3(b), will comply with the requirements of Rule 430B of the Securities Act Regulations, and will promptly notify the Representatives, and confirm the notice in writing, of (i) the effectiveness during the Prospectus Delivery Period (as defined below) of any post-effective amendment to the Registration Statement or the filing of any supplement or amendment to the Preliminary Prospectus or the Prospectus, (ii) the receipt of any comments from the Commission during the Prospectus Delivery Period, (iii) any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Preliminary Prospectus or the Prospectus or for additional information, and (iv) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of the Preliminary Prospectus or the Prospectus, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will promptly effect the filings necessary pursuant to Rule 424 and will take such steps as it deems necessary to ascertain promptly whether the Preliminary Prospectus and the Prospectus transmitted for filing under Rule 424 was received for filing by the Commission and, in the event that it was not, it will promptly file such document. The Company will use its reasonable best efforts to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments. During such period beginning on the date of this Agreement and ending on the later of the Closing Date or such date as, in the reasonable opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered in connection with sales of the Securities by an Underwriter or dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 of the Securities Act Regulations (the “Prospectus Delivery Period”), the Company will give the Representatives notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b) of the Securities Act Regulations), or any amendment, supplement or revision to the Disclosure Package or the Prospectus, whether pursuant to the Securities Act, the Exchange Act or otherwise, the Company shall furnish to the Representatives for review a copy of each such document a reasonable amount of time prior to such proposed filing or use, and the Company shall not file or use any such document to which the Representatives or counsel to the Underwriters reasonably object.

(c) Continued Compliance with Securities Laws. The Company will comply with the Securities Act and the Securities Act Regulations and the Exchange Act and the Exchange Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Registration Statement, the Disclosure Package and the Prospectus. If at any time during the Prospectus Delivery Period, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel to the Underwriters or for the Company, to amend the Registration Statement in order that the Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or to amend or supplement the Disclosure Package or the Prospectus in order that the Disclosure Package or the Prospectus, as the case may be, will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements made therein, in the light of the circumstances existing at the Initial Sale Time or at the time it is delivered or conveyed to a purchaser, not misleading, or if it shall be necessary, in the opinion of either such counsel, at any such time to amend the Registration Statement or amend or supplement the Disclosure Package or the Prospectus in order to comply with the requirements of any law, the Company will (1) promptly notify the Representatives of any such event, development or condition and (2) will promptly prepare and file with the Commission, subject to Section 3(b) hereof, such amendments or supplements as may be necessary to correct such statement or omission or to make the Registration Statement, the Disclosure Package or the Prospectus comply with such law, and the Company will furnish to the Underwriters, without charge, such number of copies of such amendments or supplements as the Underwriters may reasonably request.

12

(d) Delivery of Registration Statements. If requested by the Representatives, the Company will deliver to the Representatives and counsel for the Underwriters, without charge, signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and signed copies of all consents and certificates of experts. The Registration Statement and each amendment thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission through EDGAR, except to the extent permitted by Regulation S-T.

(e) Delivery of Prospectuses. The Company will deliver to each Underwriter, without charge, as many copies of the Preliminary Prospectus as such Underwriter may reasonably request, and the Company hereby consents to the use of such copies for purposes permitted by the Securities Act. The Company will furnish to each Underwriter, without charge, during the Prospectus Delivery Period, such number of copies of the Prospectus as such Underwriter may reasonably request. The Preliminary Prospectus and the Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission through EDGAR, except to the extent permitted by Regulation S-T.

(f) Blue Sky Compliance. The Company shall cooperate with the Representatives and counsel for the Underwriters to qualify the Securities for offer and sale under (or obtain exemptions from the application of) the Blue Sky or state securities laws of such jurisdictions as the Representatives shall reasonably request, shall comply with such laws and shall maintain such qualifications and exemptions in effect so long as required for the distribution of the Securities. The Company shall not be required to qualify as a foreign corporation or a dealer in securities or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation in respect of doing business in a jurisdiction in which it is not otherwise so subject. The Company will advise the Representatives promptly of the suspension of the qualification of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification or exemption, the Company shall use its reasonable best efforts to obtain the withdrawal thereof as promptly as possible.

(g) Use of Proceeds. The Company shall use the net proceeds received by it from the sale of the Securities sold by it in the manner described under the caption “Use of Proceeds” in the Preliminary Prospectus and the Prospectus.

(h) The Depositary. The Company will cooperate with the Underwriters and use its reasonable best efforts to permit the Securities to be eligible for clearance and settlement through the facilities of the Depositary.

During the period commencing on the date hereof and ending on the Closing Date, the Company will not, without the prior written consent of the Representatives (which consent may be withheld at the sole discretion of the Representatives), directly or indirectly, sell, offer, contract or grant any option to sell, pledge, transfer or establish an open “put equivalent position” within the meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or transfer, or announce the offering of, or file any registration statement under the Securities Act in respect of, any debt securities of the Company similar to the Securities or securities exchangeable for or convertible into debt securities similar to the Securities (other than as contemplated by this Agreement with respect to the Securities).

(k) Final Term Sheet. The Company will prepare a final term sheet containing only a description of the Securities, and will file such term sheet pursuant to Rule 433(d) under the Securities Act within the time required by such rule (such term sheet, the “Final Term Sheet”). Any such Final Term Sheet is an Issuer Free Writing Prospectus for purposes of this Agreement. A form of the Final Term Sheet for the Securities is attached hereto as Exhibit B.

(l) Permitted Free Writing Prospectuses. The Company represents that it has not made, and agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter represents that it has not made, and agrees that, unless it obtains the prior written consent of the Company and the Representatives, it will not make, any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 of the Securities Act) required to be filed by the Company with the Commission or retained by the Company under Rule 433 of the Securities Act; provided that the prior written consent of the Representatives shall be deemed to have been given in respect of any Issuer Free Writing Prospectuses included in Annex I to this Agreement. Any such free writing prospectus consented to or deemed to be consented to by the Representatives and the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (ii) has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 of the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping. The Company consents to the use by any Underwriter of a free writing prospectus that (a) is not an “issuer free writing prospectus” as defined in Rule 433, and (b) contains only (i) information describing the preliminary terms of the Securities or their offering, (ii) information permitted by Rule 134 under the Securities Act or (iii) information that describes the final terms of the Securities or their offering and that is included in the Final Term Sheet of the Company contemplated in Section 3(k).

(m) Notice of Inability to Use Automatic Shelf Registration Statement Form. If at any time during the Prospectus Delivery Period, 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 Representatives, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Securities, in a form satisfactory to the Representatives, (iii) use its reasonable best efforts to cause such registration statement of post-effective amendment to be declared effective and (iv) promptly notify the Representatives of such effectiveness. The Company will take all other action necessary or appropriate to permit the public offering and sale of the 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 such new registration statement or post-effective amendment, as the case may be.

(n) Filing Fees. The Company agrees to pay the required Commission filing fees relating to the Securities within the time required by and in accordance with Rule 456(b)(1) and 457(r) of the Securities Act.

14

(o) Compliance with Sarbanes-Oxley Act. During the Prospectus Delivery Period, the Company will comply with all applicable securities laws, rules and regulations, including, without limitation, the Sarbanes-Oxley Act, and use its reasonable best efforts to cause the Company’s directors and officers, in their capacities as such, to comply with such laws, rules and regulations, including, without limitation, the provisions of the Sarbanes-Oxley Act.

(p) No Manipulation of Price. The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, under the Exchange Act or otherwise, the stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Securities.

The Representatives, on behalf of the several Underwriters, may, in their sole discretion, waive in writing the performance by the Company of any one or more of the foregoing covenants or extend the time for their performance.

Except as provided in this Section 4, Section 6, Section 8 and Section 9 hereof, the Underwriters shall pay their own expenses, including the fees and disbursements of their counsel.

SECTION 5. Conditions of the Obligations of the Underwriters.

The indemnity agreement set forth in this Section 8 shall be in addition to any liabilities that the Company may otherwise have.

(b) Indemnification of the Company, its Directors and Officers. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company and each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company or any such director, officer or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based (i) upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) upon any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in

18

the Registration Statement, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; and to reimburse the Company, or any such director, officer or controlling person for any legal and other expenses as such expenses are reasonably incurred by the Company, or any such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Company hereby acknowledges that the only information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) are the statements set forth in (i) the last paragraph on the front cover of the Preliminary Prospectus and Prospectus regarding delivery of the Securities, (ii) the fourth full paragraph under the caption “Underwriting” in the Preliminary Prospectus and the Prospectus, and (iii) the eighth full paragraph under the caption “Underwriting” in the Preliminary Prospectus and the Prospectus; and the Underwriters confirm that such statements are correct. The indemnity agreement set forth in this Section 8 shall be in addition to any liabilities that each Underwriter may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 8 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party (the Representatives in the case of Section 8(b) and Section 9), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

19

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8 hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

SECTION 9. Contribution. If the indemnification provided for in Section 8 is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) 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 Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, 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, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial offering price of the Securities as set forth on such cover. The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such 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, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8 with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8 for purposes of indemnification.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 9.

20

Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Securities underwritten by it and distributed to the public.

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’ respective obligations to contribute pursuant to this Section 9 are several, not joint, in proportion to their respective underwriting commitments set forth opposite their names in Schedule A. For purposes of this Section 9, each director, officer, employee or agent of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company.

SECTION 10. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representatives by notice given to the Company if at any time (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or by the New York Stock Exchange; (ii) trading in securities generally on either the Nasdaq Stock Market or the New York Stock Exchange shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or FINRA; (iii) a general banking moratorium shall have been declared by any federal, New York or Georgia authorities; (iv) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to market the Securities in the manner and on the terms described in the Disclosure Package or the Prospectus or to enforce contracts for the sale of the Securities; (v) since the execution of this Agreement or since the respective dates as of which information is given in the Disclosure Package, there shall have occurred any Material Adverse Change the effect of which, in the judgment of the Representatives, makes it impracticable or inadvisable to proceed with the completion of the offer or the sale of and payment for the Securities; (vi) the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Representatives may interfere materially with the conduct of the business and operations of the Company regardless of whether or not such loss shall have been insured; or (vii) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services in the United States. Any termination pursuant to this Section 10 shall be without liability on the part of the Company to any Underwriter, except that the Company shall be obligated to reimburse the expenses of the Underwriters pursuant to Sections 4 and 6 hereof, any Underwriter to the Company, or of any party hereto to any other party except that the provisions of Section 8 and Section 9 shall at all times be effective and shall survive such termination.

SECTION 11. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company, of its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of its or their partners, officers, directors, employees or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

SECTION 14. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto, including any substitute Underwriters pursuant to Section 18 hereof, and to the benefit of the agents, employees, officers and directors and controlling persons referred to in Section 8 and Section 9, and in each case their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Company and their respective successors and the controlling person referred to in Sections 8 and 9 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters and the Company and their respective successors, and the controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm, corporation or employees. The term “successors” shall not include any purchaser of the Securities from any of the Underwriters merely by reason of such purchase.

SECTION 15. Partial Unenforceability. The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof.

SECTION 16. Governing Law Provisions. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE.

SECTION 17. Consent to Jurisdiction. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New York or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding.

The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum.

23

SECTION 18. Default of One or More of the Several Underwriters. If any one or more of the several Underwriters shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the other non-defaulting Underwriters shall be obligated, severally, in the proportions that the number of Securities set forth opposite their respective names on Schedule A bears to the aggregate number of Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Underwriters with the consent of the non-defaulting Underwriters, to purchase all of the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If any one or more of the Underwriters shall fail or refuse to purchase Securities and the aggregate number of Securities with respect to which such default occurs exceeds 10% of the aggregate number of Securities to be purchased on the Closing Date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of the non-defaulting Underwriters and the Company except that the provisions of Section 4, Section 6, Section 8 and Section 9 shall at all times be effective and shall survive such termination. In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus or any other documents or arrangements may be effected.

As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 18. Any action taken under this Section 18 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

SECTION 19. No Fiduciary Duty. The Company acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of the Company or its affiliates, stockholders, creditors or employees or any other party; (iii) no Underwriter has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Company with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement; (iv) the several Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and that the several Underwriters have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

24

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the several Underwriters with respect to the subject matter hereof. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the several Underwriters with respect to any breach or alleged breach of agency or fiduciary duty.

SECTION 20. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Agreement or any document to be signed in connection with this Agreement shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

SECTION 21. Recognition of the U.S. Special Resolution Regimes. In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States. In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

For the purposes of this Section 21:

“BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k).

“Covered Entity” means any of the following:

“Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable.

“U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

25

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return the enclosed copies hereof, whereupon this instrument, along with all counterparts hereof, shall become a binding agreement among the Underwriters and the Company in accordance with its terms.

Selling Restrictions

European Economic Area

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. The prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of notes in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of notes. The prospectus supplement and the accompanying prospectus are not a prospectus for the purposes of the Prospectus Regulation.

United Kingdom

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom (“UK”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (“EUWA”); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, “FSMA”) and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA (the “UK Prospectus Regulation”). Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation. The prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of notes in the UK will be made pursuant to an exemption under the UK Prospectus Regulation from the requirement to publish a prospectus for offers of notes. The prospectus supplement and the accompanying prospectus are not a prospectus for the purposes of the UK Prospectus Regulation.

The notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principals that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations.

The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Subject to Section 1.10 hereof, the aggregate principal amount of the Notes that may be issued under this Twelfth Supplemental Indenture is initially limited to $650,000,000.

(ii) 100% of the principal amount of the Notes to be redeemed;

(e) The Issuer will mail notice of such redemption to the registered Holders of the Notes to be redeemed not less than 10 nor more than 60 days prior to the Redemption Date.

(a) If a Change of Control Triggering Event occurs, unless the Issuer has exercised its option to redeem the Notes, the Issuer shall be required to make an offer (the “Change of Control Offer”) to each Holder of the Notes to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes on the terms set forth herein.

(b) In the Change of Control Offer, the Issuer shall be required to offer payment in cash equal to 101% of the principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Issuer’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, the Issuer shall mail or deliver electronically a notice to the Trustee and to Holders of the Notes describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the notice, which date shall be no earlier than 10 days and no later than 60 days from the date such notice is mailed or delivered electronically (the “Change of Control Payment Date”). The notice shall, if mailed or delivered electronically prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

(c) In order to accept the Change of Control Offer, the Holder must deliver to the Paying Agent, at least three Business Days prior to the Change of Control Payment Date, the Note together with the form entitled “Option of Holder to Elect Purchase” (which form is annexed to the Note) duly completed, or a telegram, telex, facsimile transmission or a letter from a member of a national securities exchange, or the Financial Industry Regulatory Authority, Inc., or a commercial bank or trust company in the United States setting forth:

(i) the name of the Holder of the Note;

(ii) the principal amount of the Note;

(iii) the principal amount of the Note to be repurchased;

(iv) the certificate number or a description of the tenor and terms of the Note;

(d) Any exercise by a Holder of its election to accept the Change of Control Offer shall be irrevocable. The Change of Control Offer may be accepted for less than the entire principal amount of the Notes, but in that event the principal amount of the Notes remaining outstanding after repurchase must be equal to $2,000 or an integral multiple of $1,000 in excess thereof.

(e) On the Change of Control Payment Date, the Issuer shall, to the extent lawful:

6

(i) accept for payment all Notes or portions of such Notes properly tendered pursuant to the Change of Control Offer;

(f) The Issuer shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Issuer, and the third party purchases all Notes properly tendered and not withdrawn under its offer. In addition, the Issuer shall not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture with respect to the Notes, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

(g) The Issuer shall comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Issuer shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.

(h) The Trustee has no obligation to determine whether a Change of Control Triggering Event has occurred and the Trustee has no obligation to provide notice to the Holders of the Notes of the occurrence of any Change of Control Triggering Event.

(iv) any contracts for production, research or development with or for the Government, directly or indirectly, providing for advance, partial or progress payments on such contracts and for a lien, paramount to all other liens, upon money advanced or paid pursuant to such contracts, or upon any material or supplies in connection with the performance of such contracts to secure such payments to the Government; and liens or other evidences of interest in favor of the Government, paramount to all other liens, on any equipment, tools, machinery, land or buildings hereafter constructed, installed or purchased by the Issuer or a Subsidiary primarily for the purpose of manufacturing or producing any product or performing any development work, directly or indirectly, for the Government to secure Indebtedness incurred and owing to the Government for the construction, installation or purchase of such equipment, tools, machinery, land or buildings.

4.800% Senior Notes due 2029

Equifax Inc., a Georgia corporation (the “Issuer,” which term includes any successor under the Original Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co. or its registered assigns, the principal sum of [•] Dollars on September 15, 2029 (the “Maturity Date”), and to pay interest thereon from August 15, 2024 (or from the most recent interest payment date to which interest has been paid or duly provided for) in U.S. dollars semi-annually in arrears on March 15 and September 15 of each year (each, an “Interest Payment Date”), commencing on March 15, 2025, and on the Maturity Date, at the rate of 4.800% per annum, until payment of said principal sum has been made or duly provided for.

The interest so payable and punctually paid or duly provided for on any Interest Payment Date and on the Maturity Date will be paid to the Holder in whose name this Note (or one or more predecessor Notes) is registered at the close of business on the “Record Date” for such payment, which will be March 1 and September 1 (regardless of whether such day is a Business Day). Any interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Record Date, and shall be paid to the Holder in whose name this Note (or one or more predecessor Notes) is registered at the close of business on a subsequent Record Date for the payment of such defaulted interest (which shall be not more than 15 days and not less than 10 days prior to the date of the payment of such defaulted interest) established by notice given by mail by or on behalf of the Issuer to the Holders of the Notes not less than 10 days preceding such subsequent Record Date. Interest on this Note will be computed on the basis of a 360-day year of twelve 30-day months.

The principal of this Note payable on the Maturity Date will be paid against presentation and surrender of this Note at the office or agency of the Issuer maintained for that purpose in The Borough of Manhattan, The City of New York. The Issuer hereby initially designates U.S. Bank Global Corporate Trust Services – New York, 100 Wall Street, Suite 1600, New York, NY 10005 as the office to be maintained by it where Notes may be presented for payment, registration of transfer, or exchange and where notices or demands to or upon the Issuer in respect of the Notes or the Indenture referred to on the reverse hereof may be served.

Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest accrued from and including the immediately preceding Interest Payment Date (or from and including August 15, 2024, in the case of the initial Interest Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be. If any Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the required payment of interest or principal or both, as the case may be, will be made on the next succeeding Business Day with the same force and effect as if it were made on the date such payment was due and no interest will accrue on the amount so payable for the period from and after such Interest Payment Date or the Maturity Date, as the case may be.

Payments of principal and interest in respect of this Note will be made by wire transfer of immediately available funds in such coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts.

Reference is made to the further provisions of this Note set forth on the reverse hereof. Such further provisions shall for all purposes have the same effect as though fully set forth at this place.

[REVERSE OF NOTE]

EQUIFAX INC.

4.800% Senior Notes due 2029

This security is one of a duly authorized issue of debentures, notes, bonds, or other evidences of indebtedness of the Issuer (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of May 12, 2016 (hereinafter called the “Original Indenture”), duly executed and delivered by the Issuer to U.S. Bank Trust Company, National Association (successor in interest to U.S. Bank National Association), as Trustee (hereinafter called the “Trustee,” which term includes any successor trustee under the Original Indenture with respect to the series of Securities of which this Note is a part), and a Twelfth Supplemental Indenture, dated as of August 15, 2024, between the Issuer and the Trustee (the “Twelfth Supplemental Indenture;” the Original Indenture as modified and supplemented by the Twelfth Supplemental Indenture is herein called the “Indenture”), to which reference is hereby made for a description of the rights, limitations of rights, obligations, duties, and immunities thereunder of the Trustee, the Issuer, and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. Capitalized terms used herein without definition shall have the meanings set forth in the Indenture. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), and may otherwise vary as provided in the Indenture or any indenture supplemental thereto. This Security is one of a series designated as the 4.800% Senior Notes due 2029 of the Issuer (the “Notes”), initially limited in aggregate principal amount to $650,000,000.

In case an Event of Default with respect to the Notes shall have occurred and be continuing, the principal hereof together with accrued interest to the date of declaration, if any, 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.

Except as otherwise may be specified herein or in the Twelfth Supplemental Indenture, prior to August 15, 2029 (one month prior to their maturity date) (the “Par Call Date”), the Issuer may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (the “Optional Redemption Price”) (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (i) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points, less (b) interest accrued to the Redemption Date; and (ii) 100% of the principal amount of the Notes to be redeemed; plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date.

On or after the Par Call Date, the Issuer may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

The Issuer will mail notice of such redemption to the registered Holders of the Notes to be redeemed not less than 10 nor more than 60 days prior to the Redemption Date. If Notes are only partially redeemed pursuant to the Twelfth Supplemental Indenture, the Notes to be redeemed will be selected by the Trustee in such manner as in its sole discretion it shall deem appropriate and fair; provided that if at the time of redemption the Notes to be redeemed are registered as a Global Note, the Depository shall determine, in accordance with its procedures, the principal amount of the Notes to be redeemed held by each of its

A-6

participants that holds a position in such Notes. The Optional Redemption Price shall be paid prior to 12:00 noon, New York time, on the Redemption Date or at such later time on such date as is then permitted by the rules of the Depository for the Notes (if then registered as a Global Note); provided that the Issuer shall deposit with the Trustee an amount sufficient to pay the Optional Redemption Price by 10:00 a.m., New York time, on the date such Optional Redemption Price is to be paid.

If a Change of Control Triggering Event occurs, unless the Issuer has exercised its option to redeem the Notes, the Issuer shall be required to make an offer (the “Change of Control Offer”) to each Holder of the Notes to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes on the terms set forth herein. In the Change of Control Offer, the Issuer shall be required to offer payment in cash equal to 101% of the principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Issuer’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, the Issuer shall mail or deliver electronically a notice to the Trustee and to Holders of the Notes describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the notice, which date shall be no earlier than 10 days and no later than 60 days from the date such notice is mailed or delivered electronically (the “Change of Control Payment Date”). The notice shall, if mailed or delivered electronically prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

In order to accept the Change of Control Offer, the Holder must deliver to the Paying Agent, at least three Business Days prior to the Change of Control Payment Date, this Security together with the form entitled “Option of Holder to Elect Purchase” (which form is annexed hereto) duly completed, or a telegram, telex, facsimile transmission or a letter from a member of a national securities exchange, or the Financial Industry Regulatory Authority, Inc., or a commercial bank or trust company in the United States setting forth:

(i) the name of the Holder of the Note;

(ii) the principal amount of the Note;

(iii) the principal amount of the Note to be repurchased;

(iv) the certificate number or a description of the tenor and terms of the Note;

(v) a statement that the Holder is accepting the Change of Control Offer; and

(vi) a guarantee that the Note, together with the form entitled “Option of Holder to Elect Purchase” duly completed, will be received by the Paying Agent at least three Business Days prior to the Change of Control Payment Date.

Any exercise by a Holder of its election to accept the Change of Control Offer shall be irrevocable. The Change of Control Offer may be accepted for less than the entire principal amount of the Notes, but in that event the principal amount of the Notes remaining outstanding after repurchase must be equal to $2,000 or an integral multiple of $1,000 in excess thereof. On the Change of Control Payment Date, the Issuer shall, to the extent lawful (1) accept for payment all Notes or portions of such Notes properly tendered pursuant to the Change of Control Offer, (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of such Notes properly tendered, and (3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of such Notes being repurchased.

A-7

The Issuer shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Issuer and the third party purchases all Notes of this series properly tendered and not withdrawn under its offer. In addition, the Issuer shall not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture with respect to the Notes, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

The Issuer shall comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Issuer shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.

We have also assumed the validity and constitutionality of each relevant statute, rule, regulation and agency action covered by this opinion letter.

This opinion letter is based as to matters of law solely on the applicable provisions of laws of the State of New York (but not including any laws, statutes, ordinances, administrative decisions, rules or regulations of any political subdivision below the state level), as currently in effect.

Insofar as the opinions expressed herein relate to or are dependent upon matters governed by Georgia law, we have relied, without independent investigation, upon, and our opinions expressed herein are subject to all of the qualifications, assumptions and limitations expressed in, the opinion dated August 15, 2024 of John J. Kelley III, Chief Legal Officer of the Company, filed as Exhibit 5.2 to the Current Report on Form 8-K relating to the offer and sale of the Notes.

The opinion expressed above with respect to the valid and binding nature of obligations may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or other laws affecting creditors’ rights and remedies (including, without limitation, the effect of statutory and other law regarding fraudulent conveyances and fraudulent, preferential or voidable transfers) and by the exercise of judicial discretion and the application of principles of equity, good faith, fair dealing, reasonableness, conscionability and materiality (regardless of whether the Notes are considered in a proceeding in equity or at law), including, without limitation, principles limiting the availability of specific performance and injunctive relief.

This opinion letter has been prepared for use in connection with the filing by the Company of a Current Report on Form 8-K, which Form 8-K will be incorporated by reference in the Registration Statement, and speaks as of the date hereof. We assume no obligation to advise of any changes in the foregoing subsequent to the delivery of this opinion letter.

We hereby consent to the filing of this opinion letter as Exhibit 5.1 to the above-described Form 8-K and to the reference to this firm under the caption “Legal Matters” in the prospectus dated August 15, 2024 that forms a part of the Registration Statement.
