Ladies and Gentlemen:

Introductory. National Fuel Gas Company, a New Jersey corporation (the “Company”), proposes to issue and sell to the several underwriters named in Schedule A (the “Underwriters”), acting severally and not jointly, the respective amounts set forth in such Schedule A of $500,000,000 aggregate principal amount of the Company’s 5.50% Notes due 2030 (the “2030 Notes”) and $500,000,000 aggregate principal amount of the Company’s 5.95% Notes due 2035 (the “2035 Notes”, and together with the 2030 Notes, the “Notes”). BofA Securities, Inc., J.P. Morgan Securities, LLC and PNC Capital Markets 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 Notes. If there are no Underwriters named in Schedule A other than the Representatives, then the terms “Underwriters” and “Representatives” shall each be deemed to refer to the Underwriters.

The Notes will be issued pursuant to an indenture, dated as of October 1, 1999, between the Company and The Bank of New York Mellon (formerly The Bank of New York), as trustee (the “Trustee”), including an Officer’s Certificate pursuant thereto (the “Indenture”). The Notes will be issued in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”), pursuant to a Blanket Letter of Representations, dated February 4, 2025 (the “DTC Agreement”), between the Company and 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. 333-273926), which contains a base prospectus (the “Base Prospectus”), to be used in connection with the public offering and sale of debt securities, including the Notes, and other securities of the Company under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the

1

“Securities Act”), 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, at each time of effectiveness 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 Notes, together with the Base Prospectus, that is first filed with the Commission pursuant to Rule 424(b) under the Securities Act 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 Notes, together with the Base Prospectus, that is first filed with the Commission pursuant to such Rule 424(b) prior to the time of filing the Prospectus. 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 2:20 p.m., New York City time, on the date of this Agreement (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 that is “contained,” “included,” “set forth,” “disclosed” or “stated” (or other references of like import) in the Registration Statement, the Prospectus or the Preliminary Prospectus shall be deemed to mean and include all such financial statements and schedules and other information that is or is 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 include the filing of any document under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”) that is or is 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 of the Company

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”), 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 contemplated or 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 (collectively, the “Trust Indenture Act”).

2

At the respective times the Registration Statement and any 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. 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 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 Section 1(a) 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 9 hereof.

Each 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 Notes will, at the time of such delivery, be identical to any electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(b) Disclosure Package. The term “Disclosure Package” shall mean (i) the Preliminary Prospectus dated February 4, 2025, (ii) any Issuer Free Writing Prospectus (as defined below), excluding any road show within the meaning of Rule 433 under the Securities Act and (iii) any other “free writing prospectus” (as defined in Rule 405 under the Securities Act) that the parties hereto shall hereafter expressly agree in writing to treat as part of the Disclosure Package. 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 9 hereof. For purposes of this Agreement, an “Issuer Free Writing Prospectus” means each “issuer free writing prospectus” (as defined in Rule 433 under the Securities Act) identified in Annex I hereto, including, without limitation, any road show within the meaning of Rule 433 under the Securities Act.

(c) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus (i) at the time they were or hereafter are filed with the Commission, complied or will comply in all material respects with the requirements of the Exchange Act and (ii) when read together with the other information in the Disclosure Package, at the Initial Sale Time, and when read together with

3

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 by virtue of the filing of any post-effective amendment, any document incorporated by reference therein pursuant to Section 13(a) or 15(d) of the Exchange Act or any form of prospectus pursuant to Rule 424(b) under the Securities Act) and (iii) at the Execution Time (with the date thereof being used as the determination date for purposes of this clause (iii)), the Company was and is a “well-known seasoned issuer” (as defined in Rule 405 under the Securities Act). The Registration Statement is an “automatic shelf registration statement” (as defined in Rule 405 under the Securities Act) that automatically became effective within three years of the date hereof. The Company has not (A) received from the Commission any notice pursuant to Rule 401(g)(2) under the Securities Act objecting to the use of the automatic shelf registration statement form or (B) ceased to be eligible to use the automatic shelf registration statement form.

(e) Company is not an Ineligible Issuer. (i) At the time of filing the Registration Statement and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii)), the Company was not and is not an Ineligible Issuer (as defined in Rule 405 under the Securities Act), without taking account of any determination by the Commission pursuant to such Rule 405 that it is not necessary that the Company be considered an Ineligible Issuer.

(f) Issuer Free Writing Prospectuses. Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the offering of the Notes under this Agreement or until any earlier date that the Company notified or notifies the Representatives 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 contained in the Registration Statement, the Preliminary Prospectus or the Prospectus. Each Issuer Free Writing Prospectus, when considered together with 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. If at any time following the issuance of an Issuer Free Writing Prospectus and during the Prospectus Delivery Period (as defined in Section 3(e) hereof), 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 contained in the Registration Statement, the Preliminary Prospectus or the Prospectus, the Company has promptly notified or will promptly notify the Representatives and has promptly amended or supplemented or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict. The foregoing two sentences do not apply to statements in or omissions from any Issuer Free Writing Prospectus 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 9 hereof.

4

(h) The Underwriting Agreement. This Agreement has been duly authorized, executed and delivered by the Company.

(i) Authorization of the Notes and the Indenture. The Notes have been duly authorized by the Company and, when the Notes have been duly executed by the Company and authenticated by the Trustee, in accordance with the provisions of the Indenture and upon payment and delivery in accordance with this Agreement, the Notes will constitute valid and legally binding obligations of the Company entitled to the benefits provided by the Indenture; the Indenture has been duly authorized by the Company and qualified under the Trust Indenture Act and constitutes a valid and legally binding instrument of the Company; and the Indenture is, and the Notes, when executed and authenticated and upon payment and delivery as aforesaid, will be enforceable in accordance with their respective terms, except as the same may be limited by (i) bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium or other similar laws affecting the enforcement of creditors’ rights and remedies generally and (ii) the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), including, without limitation, (A) the possible unavailability of specific performance, injunctive relief or any other remedy and (B) concepts of materiality, reasonableness, good faith, fair dealing and equitable subordination.

(j) Description of the Notes and the Indenture. The Notes and the Indenture conform in all material respects to the descriptions thereof contained in the Disclosure Package and the Prospectus.

The interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus fairly presents the information called for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto.

Each of National Fuel Gas Distribution Corporation, National Fuel Gas Supply Corporation, National Fuel Gas Midstream Company, LLC and Seneca Resources Company, LLC (“Seneca”) is a significant subsidiary of the Company (as such term is defined in Rule 1-02(w) of Regulation S-X) (each, a “Significant Subsidiary” and, collectively, the “Significant Subsidiaries”), has been duly incorporated or organized and is validly existing as a corporation or limited liability company, as applicable, in good standing under the laws of the jurisdiction of its incorporation or organization, as applicable, has corporate or limited liability company, as applicable, power and authority to own, lease and operate its properties and to conduct its business as described in the Disclosure Package and the Prospectus and is duly qualified as a foreign corporation or limited liability company, as applicable, to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or to be in good standing would not, individually or in the aggregate, result in a Material Adverse Change; all of the issued and outstanding capital stock or membership interests of each such Significant Subsidiary has been duly authorized and validly issued, and, in the case of capital stock, is fully paid and non-assessable and is owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance or claim. The Company did not have any subsidiary not listed on Exhibit 21 to the Annual Report on Form 10-K for the fiscal year ended September 30, 2024 that was required to be so listed.

6

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 security breach or other compromise to their IT Systems and Data, except as would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Change.

If, during the period that delivery of a prospectus is required at any time in connection with the offering or sale of the Notes, including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act (the “Prospectus Delivery Period”), any event shall occur as a result of which the Prospectus as then amended or supplemented would 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 when such Prospectus is delivered, not misleading, or, if for any other reason it shall be necessary during the Prospectus Delivery Period to amend or supplement the Prospectus in order to comply with the Securities Act, the Exchange Act or the Trust Indenture Act, the Company will notify the Representatives thereof and upon their reasonable request to file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to correct such statement or omission or to make the Prospectus so comply, and the Company will furnish without charge to each Underwriter and to any dealer in securities such number of copies of such amendment or supplement as the Representatives may reasonably request.

(f) Blue Sky Compliance. The Company shall cooperate with the Representatives and counsel for the Underwriters to qualify or register the Notes for sale under (or obtain exemptions from the application of) the state securities or “blue sky” laws of those jurisdictions designated by the Representatives, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Notes. The Company shall not be required to qualify to transact business or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified

11

or where it would be subject to taxation as a foreign business. The Company will promptly advise the Representatives of the receipt by the Company of any notification with respect to the suspension of the qualification or registration of (or any such exemption relating to) the Notes for offering, sale or trading in any jurisdiction or the initiation or threatening of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its reasonable best efforts to obtain the withdrawal thereof at the earliest possible moment.

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

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

(j) Agreement Not to Offer or Sell Additional Securities. 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 Notes or securities exchangeable for or convertible into debt securities similar to the Notes (other than as contemplated by this Agreement with respect to the Notes).

(k) Final Term Sheet. The Company will prepare a final term sheet containing only a description of the Notes and the offering thereof, in a form approved by the Underwriters and attached as Exhibit D hereto, 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.

(l) 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) under the Securities Act 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 Notes, in a form satisfactory to the Representatives, (iii) use its best efforts to cause such registration statement or 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 Notes to continue as contemplated in the registration statement that was the subject of such notice under Rule 401(g)(2) under the Securities Act 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.

12

(m) Filing Fees. The Company agrees to pay the required Commission filing fees relating to the Notes within the time required by Rule 456(b)(1) under the Securities Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) under the Securities Act.

(n) Earnings Statement. The Company will make generally available to its security holders and the Representatives as soon as practicable an earnings statement that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 of the Commission promulgated thereunder covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the “effective date” (as defined in Rule 158) of the Registration Statement.

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.

Section 4. 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, it will not make, any offer relating to the Notes that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act) required to be filed by the Company with the Commission or retained by the Company under Rule 433 under 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 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) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 under the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping. Each Underwriter represents and agrees that, unless it obtains the prior written consent of the Company and the Representatives, it has not and will not make any offer relating to the Notes that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act) that would be required to be filed with the Commission, other than information contained in the Final Term Sheet prepared and filed pursuant to Section 3(k) hereof. Prior to the preparation of the Final Term Sheet in accordance with Section 3(k) hereof, the Company and the Representatives consent to the use of the information with respect to the final terms of the Notes in communications by the Underwriters conveying information relating to the offering thereof to investors.

Section 5. Payment of Expenses. The Company agrees to pay all costs, fees and expenses incurred in connection with the performance of its obligations hereunder and in connection with the transactions contemplated hereby, including, without limitation, (i) all expenses incident to the issuance and delivery of the Notes (including all printing and engraving costs), (ii) all necessary issue, transfer and other stamp taxes in connection with the issuance and sale of the Notes to the Underwriters, (iii) all fees and expenses of the Company’s counsel, independent public or certified public accountants and other advisors to the Company, (iv) all costs and expenses incurred in connection with the preparation, printing, filing, shipping and distribution of the Registration

(the “FINRA”) of the terms of the sale of the Notes, (vii) the fees and expenses of the Trustee, including the reasonable fees and disbursements of counsel for the Trustee in connection with the Indenture and the Notes, (viii) any fees and expenses in connection with the rating of the Notes with the ratings agencies, (ix) all fees and expenses (including reasonable fees and expenses of counsel) of the Company in connection with approval of the Notes by the Depositary for “book-entry” transfer, (x) all other fees, costs and expenses referred to in Item 14 of Part II of the Registration Statement and (xi) all other fees, costs and expenses incurred in connection with the performance of its obligations hereunder for which provision is not otherwise made in this Section 5. Except as provided in this Section 5 and Sections 7, 9 and 10 hereof, the Underwriters shall pay their own costs and expenses, including the fees and disbursements of their counsel, transfer taxes on resale of any of the Notes by them and any advertising expenses connected with any offers they may make.

Section 6. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Notes as provided herein on the Closing Date shall be subject to the accuracy of the representations and warranties on the part of the Company set forth in Section 1 hereof as of each Representation Date as though then made and to the timely performance by the Company of its covenants and other obligations hereunder, and to each of the following additional conditions:

Section 9. Indemnification.

(a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its directors, officers, employees, agents and affiliates (as such term is defined in Rule 501(b) under the Securities Act (each, an “Affiliate”), and each person, if any, who controls any Underwriter within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter or such director, officer, employee, agent, Affiliate 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 the Company), 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; and to reimburse each Underwriter and each such director, officer, employee, agent, Affiliate and controlling person for any and all expenses (including the reasonable fees and disbursements of counsel chosen by the Representatives) as such expenses are reasonably incurred by such Underwriter or such director, officer, employee, agent, Affiliate or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written 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). The indemnity agreement set forth in this Section 9(a) 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, 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)

17

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 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 any 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 expense 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 regarding delivery of the Notes by the Underwriters set forth in the last paragraph on the cover page of, and the concession and reallowance figures and the paragraphs relating to stabilization of the Notes appearing under the caption “Underwriting” in, the Preliminary Prospectus and the Prospectus. The indemnity agreement set forth in this Section 9(b) 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 9 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 9, 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 that it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 9 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, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, such indemnified party shall have the right to employ its own counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party, unless: (i) the employment of such counsel has been specifically authorized in writing by the indemnifying party; (ii) the indemnifying party has failed promptly to assume the defense and employ counsel reasonably satisfactory to the indemnified party; or (iii) the named parties to any such action (including any impleaded parties) include both such indemnified party and the indemnifying party or any affiliate of the indemnifying party, and such indemnified party shall have reasonably concluded that either (x) there may be one or more legal defenses available to it that are different from or additional to those available to the indemnifying party or such affiliate of the indemnifying party or (y) a conflict may exist between such indemnified party and the indemnifying party or such affiliate of the indemnifying party (it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to a single firm of local counsel) for all such indemnified

18

parties, which firm shall be designated in writing by the Representatives and that all such reasonable fees and expenses shall be reimbursed as they are incurred). 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 9 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence, in which case the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 9 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 9(c) 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 30 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 (i) 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 (ii) 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 10. Contribution. If the indemnification provided for in Section 9 is for any reason held to be unavailable to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party hereunder, 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 in such proportion as is appropriate to reflect (i) the relative benefits received by the Company and the Underwriters from the offering of the Notes pursuant to this Agreement, (ii) the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses and (iii) any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters in connection with the offering of the Notes pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes 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 front cover page of the Prospectus bear to the aggregate initial public offering price of the Notes 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.

19

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 9(c), any reasonable legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 10 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 that does not take account of the equitable considerations referred to in this Section 10.

Notwithstanding the provisions of this Section 10, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such 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 pursuant to this Section 10 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their names in Schedule A. For purposes of this Section 10, each director, officer, employee, agent and Affiliate 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 11. Default of One or More of the Several Underwriters. If, on the Closing Date, any one or more of the several Underwriters shall fail or refuse to purchase Notes that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Notes, which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate principal amount of the Notes to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportion to the aggregate principal amounts of such Notes set forth opposite their respective names on Schedule A bears to the aggregate principal amount of such Notes set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Representatives (excluding any defaulting Underwriter) with the consent of the non-defaulting Underwriters, to purchase such Notes that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase such Notes and the aggregate principal amount of such Notes with respect to which such default occurs exceeds 10% of the aggregate principal amount of Notes to be purchased on such date, and arrangements satisfactory to the Representatives (excluding any defaulting Underwriter) and the Company for the purchase of such Notes are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the

20

provisions of Sections 5, 7, 9, 10 and 18 hereof 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, 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 11. Any action taken under this Section 11 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

Section 12. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representatives by written notice given to the Company if at any time since the Execution Time (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or the New York Stock Exchange, or trading in securities generally on either the Nasdaq Stock Market or the New York Stock Exchange shall have been suspended or materially limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or the FINRA; (ii) a general banking moratorium shall have been declared by any of federal or New York authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity involving the United States, 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 offer, sell or deliver the Notes in the manner and on the terms described in the Disclosure Package or to enforce contracts for the sale of securities; or (iv) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services. Any termination pursuant to this Section 12 shall be without liability of any party to any other party except as provided in Sections 5 and 7 hereof, and provided further that Sections 5, 7, 9, 10 and 18 hereof shall survive such termination and remain in full force and effect.

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.

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 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 (i) will remain operative and in full force and effect, regardless of any (A) investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the officers or employees of any Underwriter, or any person controlling the Underwriter, the Company, the officers or employees of the Company, or any person controlling the Company, as the case may be or (B) acceptance of the Notes and payment for them hereunder and (ii) will survive delivery of and payment for the Notes sold hereunder and any termination of this Agreement.

NATIONAL FUEL GAS COMPANY

5.50% NOTES DUE 2030

NATIONAL FUEL GAS COMPANY, a corporation duly organized and existing under the laws of the State of New Jersey (herein referred to as the “Company,” which term includes any successor Person under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to         or registered assigns, the principal sum of         on the Maturity Date specified above, and to pay interest thereon at the Interest Rate specified above, subject to adjustment as set forth on the reverse hereof under “Interest Rate Adjustment,” semiannually on the Interest Payment Dates specified above of each

year and on the Maturity Date, from the Original Interest Accrual Date specified above or from the most recent Interest Payment Date to which interest has been paid, unless the Company shall default in the payment of interest due on such Interest Payment Date, in which case interest shall be payable from the next preceding Interest Payment Date to which interest has been paid, or, if no interest has been paid on this Security, from the Original Interest Accrual Date. In the event that the Maturity Date or any date fixed for redemption is not a Business Day, then payment of principal and interest payable on such date shall be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of such delay) with the same force and effect as if made on such Maturity Date or date fixed for redemption. In the event that any Interest Payment Date is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of such delay) with the same force and effect as if made on such Interest Payment Date. The Initial Interest Payment Date shall be September 15, 2025, and the payment on that date shall include all interest accrued from the Original Interest Accrual Date. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date shall, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be (a) the Business Day immediately preceding such Interest Payment Date so long as Securities of this series remain in book-entry only form or (b) the 15th calendar day prior to such Interest Payment Date if Securities of this series do not remain in book-entry only form; provided, however, that interest payable at Maturity shall be paid to the Person to whom principal shall be paid. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice of which shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture.

Payment of the principal of and premium, if any, and interest on this Security shall be made at the office or agency of the Company maintained for that purpose in The City of New York, the State of New York in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that (a) at the option of the Company, interest on this Security may be paid by check mailed to the address of the person entitled thereto, as such address shall appear on the Security Register or by wire transfer to an account designated by the person entitled thereto, and (b) upon the written request of a Holder of not less than $10 million in aggregate principal amount of Securities of this series delivered to the Company and the Paying Agent at least ten days prior to any Interest Payment Date, payment of interest on such Securities to such Holder on such Interest Payment Date shall be made by wire transfer of immediately available funds to an account maintained within the continental United States specified by such Holder or, if such Holder maintains an account with the entity acting as Paying Agent, by deposit into such account.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

[FORM OF CERTIFICATE OF AUTHENTICATION]

CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated therein referred to in the within- mentioned Indenture.

Dated: February 19, 2025

[Signature Page to the Certificate of Authentication (2030 Notes)]

[FORM OF REVERSE OF NOTE]

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture (For Unsecured Debt Securities), dated as of October 1, 1999 (herein, together with any amendments or supplements thereto, called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon (formerly known as The Bank of New York), as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture, including the Board Resolutions and Officer’s Certificate filed with the Trustee on February 19, 2025 creating the series designated on the face hereof, for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The acceptance of this Security shall be deemed to constitute the consent and agreement by the Holder hereof to all terms and provisions of the Indenture.

Optional Redemption

Prior to February 15, 2030 (one month prior to their maturity date) (the “Par Call Date”), the Company may redeem the Securities at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Securities 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 date of redemption, and

(2) 100% of the principal amount of the Securities to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the redemption date.

On or after the Par Call Date, the Company may redeem the Securities, 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 Securities being redeemed plus accrued and unpaid interest thereon to the redemption date.

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor

designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The Company shall notify the Trustee of the redemption price promptly after the calculation thereof and the Trustee will not be responsible or liable for any calculation of the redemption price or of any component thereof, or for determining whether manifest error has occurred.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of Securities to be redeemed. As provided in the Indenture, notice of redemption at the election of the Company as aforesaid may state that such redemption shall be conditional upon the receipt by the applicable Paying Agent or Agents of money sufficient to pay the principal of and premium, if any, and interest, if any, on the Securities on or prior to the date fixed for such redemption; a notice of redemption so conditioned shall be of no force or effect if such money is not so received and, in such event, the Company shall not be required to redeem the Securities.

- 2 -

In the case of a partial redemption, selection of the Securities for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Securities of a principal amount of $2,000 or less will be redeemed in part. If any Security is to be redeemed in part only, the notice of redemption that relates to the Security will state the portion of the principal amount of the Security to be redeemed. Except in the case of global notes, a new Security in a principal amount equal to the unredeemed portion of the Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. In the case of the global notes, DTC, or its nominee, will determine the allocation of the redemption price amongst the ownership interest of each actual purchaser of notes in such global note in accordance with the policies and procedures of the depositary.

Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Securities or portions thereof called for redemption.

Interest Rate Adjustment

The interest rate payable on the Securities will be subject to adjustments from time to time if an Interest Rate Adjustment Triggering Event occurs or, if following an Interest Rate Adjustment Triggering Event, any of Moody’s, S&P or Fitch, or any Substitute Rating Agency, subsequently upgrades the debt rating assigned to the Securities, in each case in the manner described below. The interest rate payable on the Securities is also subject to adjustments if any of the Rating Agencies ceases to rate the Securities or fails to make a rating of the Securities publicly available for reasons outside the Company’s control, subject to the conditions described below.

If an Interest Rate Adjustment Triggering Event occurs, the interest rate payable on the Securities will increase from the interest rate payable on the Securities on the date of their issuance by an amount equal to the sum of the percentages set forth in the following tables opposite the ratings of the Securities immediately following such Interest Rate Adjustment Triggering Event; provided, that only the two lowest ratings assigned to the Securities will be taken into account for purposes of any interest rate adjustment:

- 3 -

If at any time after an Interest Rate Adjustment Triggering Event has occurred, any Rating Agency (or, in either case, a Substitute Rating Agency therefor), as the case may be, subsequently increases its rating of the Securities to any of the threshold ratings set forth above, the interest rate payable on the Securities will be decreased such that the interest rate payable for the Securities equals the interest rate payable on the Securities on the date of their issuance plus (if applicable) the percentages set forth opposite the ratings from the tables above with respect to the two lowest ratings assigned to the Securities in effect immediately following the increase. If at any time after an Interest Rate Adjustment Triggering Event has occurred, Moody’s (or any Substitute Rating Agency therefor) subsequently increases its rating of the Securities to Baa3 (or its equivalent, in the case of a Substitute Rating Agency) or higher, S&P (or any Substitute Rating Agency therefor) increases its rating to BBB- (or its equivalent, in the case of a Substitute Rating Agency) or higher and Fitch (or any Substitute Rating Agency therefor) increases its rating to BBB- (or its equivalent, in the case of a Substitute Rating Agency) or higher, the interest rate payable on the Securities will be decreased to the interest rate payable on the Securities on the date of their issuance (and if any two Rating Agencies increase their ratings assigned to the Securities to Baa3, BBB- or BBB- or higher, as the case may be, and the third Rating Agency does not, the interest rate payable on the Securities will be decreased so that it does not reflect any increase attributable to the upgrading Rating Agencies). In addition, the interest rates on the Securities will permanently cease to be subject to any adjustment described above (notwithstanding any subsequent decrease in the ratings by any or all Rating Agencies) if the Securities become rated Baa1, BBB+ or BBB+, as the case may be (or the equivalent of any such rating, in the case of a Substitute Rating Agency), or higher by any two of Moody’s, S&P and Fitch (or, in any case, a Substitute Rating Agency thereof), respectively.

Each adjustment required by any decrease or increase in a rating set forth above, whether occasioned by the action of any of the Rating Agencies (or, in either case, a Substitute Rating Agency therefor), shall be made independent of any and all other adjustments. In no event shall (1) the interest rate for the Securities be reduced to below the interest rate payable on the Securities on the date of their issuance or (2) the total increase in the interest rate payable on the Securities exceed 2.00% above the interest rate payable on the Securities on the date of the issuance.

- 4 -

No adjustments in the interest rate payable on the Securities shall be made solely as a result of a Rating Agency ceasing to provide a rating of the Securities. If at any time a Rating Agency ceases to provide a rating of the Securities for a reason beyond the Company’s control, the Company will use its commercially reasonable efforts to obtain a rating of the Securities from another Rating Agency, to the extent one exists, and if another such Rating Agency rates the Securities (such Rating Agency, a “Substitute Rating Agency”), for purposes of determining any increase or decrease in the interest rate payable on the Securities pursuant to the tables above (a) such Substitute Rating Agency will be substituted for the last Rating Agency to provide a rating of the Securities but which has since ceased to provide such rating and (b) the relative ratings scale used by such Substitute Rating Agency to assign ratings to senior unsecured debt shall be determined in good faith by an independent investment banking institution of national standing appointed by the Company and, for purposes of determining the applicable ratings included in the applicable table above with respect to such Substitute Rating Agency, such ratings will be deemed to be the equivalent ratings used by Moody’s, S&P or Fitch, as applicable, in such table. If a Rating Agency has ceased to provide a rating of the Securities for any reason and the Company is unable to or otherwise does not designate a successor Rating Agency, that Rating Agency shall be deemed to have rated the Securities at the lowest level contemplated by the tables above; however, if only one of the Rating Agencies ceases to provide a rating of the Securities for any reason, the deemed rating of that Rating Agency shall be disregarded for purposes of all interest rate adjustments. If two of the Rating Agencies cease to provide a rating of the Securities for any reason and the Company is unable to or otherwise does not designate a successor Rating Agency for both Rating Agencies, the deemed rating of only one of such two Rating Agencies shall be disregarded. If all three Rating Agencies cease to provide a rating of the Securities for any reason and the Company is unable to or otherwise does not designate a successor Rating Agency for all three Rating Agencies, the interest rate on the Securities will increase to, or remain at, as the case may be, 2.00% above the interest rate payable on the Securities on the date of their issuance.

Any interest rate increase or decrease described above will take effect from the first day of the semi-annual interest period commencing after the date on which a rating change occurs that requires an adjustment in the interest rate.

If the interest rate payable on the Securities is increased as described in this “Interest Rate Adjustment,” the term “interest,” as applicable to the Securities, will be deemed to include any such additional interest unless the context otherwise requires.

The Company shall give the Trustee prompt written notice of any such increase or decrease, pursuant to this section, in the interest rate on the Securities, which notice shall set forth the amount of such increase or decrease, the basis therefor and the date from which such increase or decrease shall take effect. The Trustee shall have no duty to independently monitor or determine whether any such increase or decrease has occurred, the amount of such increase or decrease or the date from which such increase or decrease shall take effect and shall be fully- protected in relying on an officer’s certificate stating that an interest rate adjustment has occurred and the amount of such adjustment.

[FORM OF CERTIFICATE OF AUTHENTICATION]

CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated therein referred to in the within- mentioned Indenture.

Dated: February 19, 2025

[Signature Page to the Certificate of Authentication (2035 Notes)]

[FORM OF REVERSE OF NOTE]

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture (For Unsecured Debt Securities), dated as of October 1, 1999 (herein, together with any amendments or supplements thereto, called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon (formerly known as The Bank of New York), as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture, including the Board Resolutions and Officer’s Certificate filed with the Trustee on February 19, 2025 creating the series designated on the face hereof, for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The acceptance of this Security shall be deemed to constitute the consent and agreement by the Holder hereof to all terms and provisions of the Indenture.

Optional Redemption

Prior to December 15, 2034 (three months prior to their maturity date) (the “Par Call Date”), the Company may redeem the Securities at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Securities 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 25 basis points less (b) interest accrued to the date of redemption, and

(2) 100% of the principal amount of the Securities to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the redemption date.

On or after the Par Call Date, the Company may redeem the Securities, 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 Securities being redeemed plus accrued and unpaid interest thereon to the redemption date.

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor

designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The Company shall notify the Trustee of the redemption price promptly after the calculation thereof and the Trustee will not be responsible or liable for any calculation of the redemption price or of any component thereof, or for determining whether manifest error has occurred.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of Securities to be redeemed. As provided in the Indenture, notice of redemption at the election of the Company as aforesaid may state that such redemption shall be conditional upon the receipt by the applicable Paying Agent or Agents of

- 2 -

money sufficient to pay the principal of and premium, if any, and interest, if any, on the Securities on or prior to the date fixed for such redemption; a notice of redemption so conditioned shall be of no force or effect if such money is not so received and, in such event, the Company shall not be required to redeem the Securities.

In the case of a partial redemption, selection of the Securities for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Securities of a principal amount of $2,000 or less will be redeemed in part. If any Security is to be redeemed in part only, the notice of redemption that relates to the Security will state the portion of the principal amount of the Security to be redeemed. Except in the case of global notes, a new Security in a principal amount equal to the unredeemed portion of the Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. In the case of the global notes, DTC, or its nominee, will determine the allocation of the redemption price amongst the ownership interest of each actual purchaser of notes in such global note in accordance with the policies and procedures of the depositary.

Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Securities or portions thereof called for redemption.

Interest Rate Adjustment

The interest rate payable on the Securities will be subject to adjustments from time to time if an Interest Rate Adjustment Triggering Event occurs or, if following an Interest Rate Adjustment Triggering Event, any of Moody’s, S&P or Fitch, or any Substitute Rating Agency, subsequently upgrades the debt rating assigned to the Securities, in each case in the manner described below. The interest rate payable on the Securities is also subject to adjustments if any of the Rating Agencies ceases to rate the Securities or fails to make a rating of the Securities publicly available for reasons outside the Company’s control, subject to the conditions described below.

If an Interest Rate Adjustment Triggering Event occurs, the interest rate payable on the Securities will increase from the interest rate payable on the Securities on the date of their issuance by an amount equal to the sum of the percentages set forth in the following tables opposite the ratings of the Securities immediately following such Interest Rate Adjustment Triggering Event; provided, that only the two lowest ratings assigned to the Securities will be taken into account for purposes of any interest rate adjustment:

- 3 -

If at any time after an Interest Rate Adjustment Triggering Event has occurred, any Rating Agency (or, in either case, a Substitute Rating Agency therefor), as the case may be, subsequently increases its rating of the Securities to any of the threshold ratings set forth above, the interest rate payable on the Securities will be decreased such that the interest rate payable for the Securities equals the interest rate payable on the Securities on the date of their issuance plus (if applicable) the percentages set forth opposite the ratings from the tables above with respect to the two lowest ratings assigned to the Securities in effect immediately following the increase. If at any time after an Interest Rate Adjustment Triggering Event has occurred, Moody’s (or any Substitute Rating Agency therefor) subsequently increases its rating of the Securities to Baa3 (or its equivalent, in the case of a Substitute Rating Agency) or higher, S&P (or any Substitute Rating Agency therefor) increases its rating to BBB- (or its equivalent, in the case of a Substitute Rating Agency) or higher and Fitch (or any Substitute Rating Agency therefor) increases its rating to BBB- (or its equivalent, in the case of a Substitute Rating Agency) or higher, the interest rate payable on the Securities will be decreased to the interest rate payable on the Securities on the date of their issuance (and if any two Rating Agencies increase their ratings assigned to the Securities to Baa3, BBB- or BBB- or higher, as the case may be, and the third Rating Agency does not, the interest rate payable on the Securities will be decreased so that it does not reflect any increase attributable to the upgrading Rating Agencies). In addition, the interest rates on the Securities will permanently cease to be subject to any adjustment described above (notwithstanding any subsequent decrease in the ratings by any or all Rating Agencies) if the Securities become rated Baa1, BBB+ or BBB+, as the case may be (or the equivalent of any such rating, in the case of a Substitute Rating Agency), or higher by any two of Moody’s, S&P and Fitch (or, in any case, a Substitute Rating Agency thereof), respectively.

Each adjustment required by any decrease or increase in a rating set forth above, whether occasioned by the action of any of the Rating Agencies (or, in either case, a Substitute Rating Agency therefor), shall be made independent of any and all other adjustments. In no event shall (1) the interest rate for the Securities be reduced to below the interest rate payable on the Securities on the date of their issuance or (2) the total increase in the interest rate payable on the Securities exceed 2.00% above the interest rate payable on the Securities on the date of the issuance.

- 4 -

No adjustments in the interest rate payable on the Securities shall be made solely as a result of a Rating Agency ceasing to provide a rating of the Securities. If at any time a Rating Agency ceases to provide a rating of the Securities for a reason beyond the Company’s control, the Company will use its commercially reasonable efforts to obtain a rating of the Securities from another Rating Agency, to the extent one exists, and if another such Rating Agency rates the Securities (such Rating Agency, a “Substitute Rating Agency”), for purposes of determining any increase or decrease in the interest rate payable on the Securities pursuant to the tables above (a) such Substitute Rating Agency will be substituted for the last Rating Agency to provide a rating of the Securities but which has since ceased to provide such rating and (b) the relative ratings scale used by such Substitute Rating Agency to assign ratings to senior unsecured debt shall be determined in good faith by an independent investment banking institution of national standing appointed by the Company and, for purposes of determining the applicable ratings included in the applicable table above with respect to such Substitute Rating Agency, such ratings will be deemed to be the equivalent ratings used by Moody’s, S&P or Fitch, as applicable, in such table. If a Rating Agency has ceased to provide a rating of the Securities for any reason and the Company is unable to or otherwise does not designate a successor Rating Agency, that Rating Agency shall be deemed to have rated the Securities at the lowest level contemplated by the tables above; however, if only one of the Rating Agencies ceases to provide a rating of the Securities for any reason, the deemed rating of that Rating Agency shall be disregarded for purposes of all interest rate adjustments. If two of the Rating Agencies cease to provide a rating of the Securities for any reason and the Company is unable to or otherwise does not designate a successor Rating Agency for both Rating Agencies, the deemed rating of only one of such two Rating Agencies shall be disregarded. If all three Rating Agencies cease to provide a rating of the Securities for any reason and the Company is unable to or otherwise does not designate a successor Rating Agency for all three Rating Agencies, the interest rate on the Securities will increase to, or remain at, as the case may be, 2.00% above the interest rate payable on the Securities on the date of their issuance.

Any interest rate increase or decrease described above will take effect from the first day of the semi-annual interest period commencing after the date on which a rating change occurs that requires an adjustment in the interest rate.

If the interest rate payable on the Securities is increased as described in this “Interest Rate Adjustment,” the term “interest,” as applicable to the Securities, will be deemed to include any such additional interest unless the context otherwise requires.

The Company shall give the Trustee prompt written notice of any such increase or decrease, pursuant to this section, in the interest rate on the Securities, which notice shall set forth the amount of such increase or decrease, the basis therefor and the date from which such increase or decrease shall take effect. The Trustee shall have no duty to independently monitor or determine whether any such increase or decrease has occurred, the amount of such increase or decrease or the date from which such increase or decrease shall take effect and shall be fully- protected in relying on an officer’s certificate stating that an interest rate adjustment has occurred and the amount of such adjustment.
