Item 1.01

Entry into a Material Definitive Agreement

On June 8, 2026, ATI Inc. (the “Company”) completed its offering and sale of $450 million aggregate principal amount of the Company’s unsecured 5.875% Senior Notes due 2033 (the “Notes”). The offering and sale of the Notes (the “Offering”) were made pursuant to the Company’s shelf registration statement filed with the Securities and Exchange Commission.

The Notes were issued pursuant to the Indenture, dated as of September 14, 2021 (the “Indenture”), between the Company and Computershare Trust Company, N.A., as successor trustee to Wells Fargo Bank, National Association, as trustee (the “Trustee”), as supplemented by the Third Supplemental Indenture, dated as of June 8, 2026 (the “Supplemental Indenture”), between the Company and the Trustee.

The Notes will accrue interest at the rate of 5.875% per annum and will mature on June 15, 2033. The Notes will be payable in cash semi-annually in arrears on each June 15 and December 15, commencing December 15, 2026.

Prior to June 15, 2029, the Company may redeem the Notes at its option, at any time in whole or from time to time in part, at a redemption price equal to 100% of the principal amount of the Notes redeemed plus an applicable premium determined as set forth in the Supplemental Indenture as of, and accrued and unpaid interest to but not including, the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

On and after June 15, 2029, the Company may redeem the Notes, at its option, at any time in whole or from time to time in part, at redemption prices specified in the Supplemental Indenture, plus accrued and unpaid interest to but not including the redemption date on the principal amount of the Notes to be redeemed.

In addition, at any time prior to June 15, 2029, the Company may, at its option and at any time, redeem up to 35% of the aggregate principal amount of the Notes at a redemption price equal to 105.875% of the aggregate principal amount thereof, plus accrued and unpaid interest to but not including the redemption date on the principal amount of the Notes to be redeemed, with the net proceeds of one or more of certain equity offerings; provided that at least 65% of the aggregate principal amount of the Notes remain outstanding immediately after the occurrence of each such redemption.

If an event of default with respect to the Notes occurs, the principal amount of the Notes, plus premium, if any, and accrued and unpaid interest may be declared immediately due and payable, subject to certain conditions. These amounts automatically become due and payable in the case of certain types of bankruptcy, insolvency or reorganization events of default involving the Company.

The foregoing is a summary of the material terms and conditions of the Indenture, as supplemented by the Supplemental Indenture, and is not a complete discussion. Accordingly, the foregoing is qualified in its entirety by reference to the full text of the Indenture and the Supplemental Indenture, which are filed as Exhibit 4.1 and Exhibit 4.2, respectively, to this Current Report on Form 8-K, each of which is incorporated herein by reference.

Schedule I hereto

c/o Goldman Sachs & Co. LLC

200 West Street

New York, NY 10282

Ladies and Gentlemen:

ATI Inc., a Delaware

corporation (the “Company”), proposes to issue and sell to the several Underwriters listed in Schedule I hereto (the “Underwriters”), for whom you are acting as Representative (the “Representative”), an aggregate

of $450,000,000 principal amount of its 5.875% Senior Notes due 2033 (the “Securities”). The Securities are to be issued under a base indenture, dated as of September 14, 2021 (the “Base Indenture”), as supplemented by

the Third Supplemental Indenture, to be dated as of the Closing Date (as defined below) (the “Third Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and Computershare Trust

Company, N.A., as successor trustee to Wells Fargo Bank, National Association (the “Trustee”).

The Company hereby confirms

its agreement with the several Underwriters concerning the purchase and sale of the Securities (this “Agreement”), as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”)

under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), an automatic shelf registration statement, as defined in Rule 405 of the Securities Act, on

Form S-3 (File No. 333-277308) including a base prospectus (the “Base Prospectus”), relating to various securities to be issued from time to time by the

Company, including the Securities. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration

statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means the Base Prospectus and any

prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act that omits Rule 430 Information, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers

pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Securities. Any reference in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and

include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary

Prospectus or the Prospectus, as the case may be and any reference to “amend”, “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed

to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be

incorporated by reference therein. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the time when sales of the Securities were first made (the “Time of

Sale”), the Company had prepared the following information (collectively, the “Time of Sale Information”): a Preliminary Prospectus dated June 3, 2026, and each “free writing prospectus” (as defined pursuant to

Rule 405 under the Securities Act) listed on Schedule IIA hereto as constituting part of the Time of Sale Information.

Purchase of the Securities by the Underwriters.

Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the

Company the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule I hereto at a price equal to 98.875% of the principal amount thereof plus accrued interest, if any, from June 8, 2026 to the Closing

Date.

(b) The Company understands that the Underwriters intend to make a public offering of the Securities as soon after the

facilities of The Depository Trust Company (“DTC”) and shall be in global form unless the Representative shall instruct otherwise, with any transfer taxes payable in connection with the sale of such Securities duly paid by the Company.

(e) The Company acknowledges and agrees that each Underwriter is acting solely in the capacity of an arm’s length contractual

counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any

other person. Additionally, none of the Representative or any other Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its

own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with

respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the

(b) Time of Sale Information. The Time of Sale Information, at the Time of Sale, did not, and at the Closing Date will not,

included in the Prospectus has been omitted from the Time of Sale Information and no statement of material fact included in the Time of Sale Information that is required to be included in the Prospectus has been omitted therefrom.

(c) Issuer Free Writing Prospectus. The Company (including its agents and representatives, other than the Underwriters in their

capacity as such) has not prepared, made, used, authorized, approved or referred to and will not prepare, make, use, authorize, approve or refer to any “written communication” (as defined in Rule 405 under the Securities Act) that

Underwriter through the Representative expressly for use in any Issuer Free Writing Prospectus, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in

Section 7(b) hereof.

the Commission and no proceeding for that purpose or pursuant to Section 8A of the Securities Act against the Company or related to the offering has been initiated or, to the knowledge of the Company, threatened by the Commission; as of each

date and time the Registration Statement, and any post-effective amendment or amendments thereto, became or becomes effective, the Registration Statement complied and will comply in all material respects with the Securities Act and the Trust

Indenture Act of 1939, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Trust Indenture Act”), and did not and will not contain any untrue statement of a material fact or omit to state a material

are true and correct, (ii) confirming that the other representations and warranties of the Company in this Agreement are true and correct and that the Company has complied with all agreements and satisfied all conditions on its part to be

negative assurance letter, dated the Closing Date and addressed to the Underwriters, in form and substance reasonably satisfactory to the Representative, to the effect set forth in Annex B hereto.

(h) Opinion of Counsel for the Underwriters. The Representative shall have received on and as of the Closing Date an opinion and

negative assurance letter of Cravath, Swaine & Moore LLP, counsel for the Underwriters, dated the Closing Date, with respect to such matters as the Representative may reasonably request, and such counsel shall have received such documents

and information as they may reasonably request to enable them to pass upon such matters.

(i) No Legal Impediment to Issuance.

No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any federal, state or foreign governmental or regulatory authority that would, as of the Closing Date, prevent the issuance

or sale of the Securities; and no injunction or order of any federal, state or foreign court shall have been issued that would, as of the Closing Date, prevent the issuance or sale of the Securities.

(j) Good Standing. The Representative shall have received on and as of the Closing Date satisfactory evidence of the good standing of

the Company and its Significant Subsidiaries in their respective jurisdictions of organization and their good standing as foreign entities in such other jurisdictions as the Representative may reasonably request, in each case in writing or any

standard form of telecommunication from the appropriate governmental authorities of such jurisdictions.

All opinions, letters, certificates and evidence mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the

7. Indemnification

and Contribution.

(a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each

Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses,

claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several,

that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be

stated therein or necessary in order to make the statements therein, not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer

Free Writing Prospectus or any Preliminary Prospectus, or caused by any

omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each

case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any

Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information

described as such in subsection (b) below.

(b) Indemnification of the Company. Each Underwriter agrees, severally and

not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or

Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission

or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use in the

Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Preliminary Prospectus, it being understood and agreed upon that the only such information furnished by any Underwriter

consists of the following information in the Preliminary Prospectus and Prospectus furnished on behalf of each Underwriter: the discount figures appearing in the third paragraph under the caption “Underwriting” and the information

contained in the eighth, ninth and tenth paragraphs under the caption “Underwriting”.

If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or

(b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the

Indemnifying Person shall not relieve it from any liability that it may have under this Section 7 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and

provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 7. If any such proceeding shall be brought

or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others

entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any

Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually

agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be

legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the

Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any

proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or

reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons

of such Underwriter shall be designated in writing by the Representative and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any

control persons of the Company shall be designated in writing by the Company. The Indemnifying Person 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 Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an

Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person 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 the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in

accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement, compromise or consent to the entry of judgment in any pending or

threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement, compromise or consent (x) includes an

unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to

or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If

the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such

paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (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 from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such

proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions that

resulted in such losses, claims, damages or liabilities, 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 shall be deemed to be in the same

respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as

set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other

things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent,

knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 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 paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and

liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding

the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and

commissions received by such Underwriter with respect to the offering of the Securities 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 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not

exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company, if after

the execution and delivery of this Agreement and prior to the Closing Date: (i) trading generally shall have been suspended or materially limited on or by the New York Stock Exchange; (ii) trading of any securities issued or guaranteed by

the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been

declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in

the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the Closing Date on the terms and in the manner contemplated by this Agreement,

the Time of Sale Information and the Prospectus.

10. Defaulting Underwriter. (a) If, on the Closing Date, any Underwriter

defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other

persons satisfactory to the Company on the terms contained in this Agreement. If, within thirty-six (36) hours after any such default by any Underwriter, the

non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six (36) hours

within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a

defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date for up to five (5) full business days in order to effect any changes that in the opinion of

counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the

Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in

Schedule I hereto that, pursuant to this Section 10, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased on the Closing Date does not exceed one-eleventh of the aggregate principal amount of all of the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the

principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such

defaulting Underwriter or Underwriters for which such arrangements have not been made.

defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased on

the Closing Date exceeds one-eleventh of the aggregate principal amount of all of the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall

terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that

the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

11. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or

cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any

taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale

Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the

Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions

as the Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters); (vi) any fees charged by the rating agencies for rating the

Securities; (vii) the fees and expenses of the Trustee and the paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with any filing with, and

clearance of the offering by, the Financial Industry Regulatory Authority; and (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; provided, however, that

except as provided in Section 7 or this Section 11, the Underwriters shall pay their own costs and expenses, including without limitation the fees and disbursements of their counsel and any advertising expenses (other than with respect to

any road show presentation) connected with any offers they make.

(b) If (i) this Agreement is terminated pursuant to Section 9,

(ii) the Company for any reason fails to tender the Securities for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement, the Company agrees to reimburse the

Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this

Agreement and the offering contemplated hereby.

12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the

benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Underwriter referred to in Section 7 hereof. Nothing in

this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Underwriter shall be

deemed to be a successor merely by reason of such purchase.

13. Survival. The respective indemnities, rights of contribution, representations,

warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery

of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Underwriters.

14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term

“affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and

15. Miscellaneous.

(a) Authority of the Representative. Any action by the Underwriters hereunder may be taken by the Representative on behalf of

the Underwriters, and any such action taken by the Representative shall be binding upon the Underwriters.

(b) Notices. All

notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted and confirmed by any standard form of telecommunication. Notices to the Underwriters shall be given to the

Representative c/o Goldman Sachs & Co. LLC, 200 West Street, New York, New York 10282-2198 (Attention: Registration Department, Email: registration-syndops@ny.email.gs.com). Notices to the Company shall be given to it at 2021 McKinney

(c)

Governing Law. This Agreement and any claim, controversy or dispute arising under or relating to this Agreement shall be governed by and construed in accordance with the laws of the State of New York.

and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

(e) Recognition of the U.S. Special Resolution Regime.

(i) 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.

(ii) 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.

As used in this Section 15(e):

“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).

We expect that delivery of the Notes will be made to investors on or about June 8, 2026, which will be the third business

day following the date of the final prospectus supplement (such settlement being referred to as “T+3”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the

secondary market are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to one business day before delivery will be required, by virtue of

the fact that the notes initially settle in T+3, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes prior to their date of delivery

hereunder should consult their advisors.

The Issuer has filed a registration statement (including a preliminary prospectus supplement) with the

SEC for the offering to which this communication relates. Before you invest, you should read the preliminary prospectus supplement included in that registration statement and other documents we have filed with the SEC for more complete information

about us and this offering. You may get these documents for free by visiting EDGAR on the SEC website at www.sec.gov. Alternatively, we or the underwriters will arrange to send you the prospectus if you request it by calling Goldman Sachs &

Co. LLC toll-free at (866) 471-2526.

the Company Order for the authentication and delivery of the Notes pursuant to Section 303 of the Base Indenture. In addition, the Company may issue, from time to time in accordance with the provisions of the Indenture, additional Notes having

the same terms and conditions as the Notes issued on the date hereof in all respects (except for the payment of interest accruing prior to the issue date of such additional Notes), so that such additional Notes shall be consolidated and form a

single series with the Notes issued on the date hereof and shall be governed by the terms of the Indenture.

SECTION 2.02.

Maturity. The principal amount of the Notes shall be due and payable on June 15, 2033.

SECTION 2.03. Form

and Payment. The Notes shall be issued in substantially the form set forth on Exhibit A hereto and shall have the terms set forth in such form and shall initially be Global Securities for purposes of the Base Indenture. The

Notes shall be issued in fully registered book-entry form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The Depositary in respect of the Notes represented by Global Securities shall be The Depository Trust Company. The Global Securities

representing the Notes shall be deposited with, or on behalf of, the Depositary and shall be registered in the name of its nominee, Cede & Co. Except as otherwise set forth in Section 305 of the Base Indenture, the Global Securities

may be transferred, in whole and not in part, only to another nominee of the Depositary or to a successor of the Depositary or its nominee.

The Trustee shall act as Paying Agent for the Notes. The Company may choose to pay interest by mailing checks or making wire or other

electronic funds transfers. All money paid by the Company to any Paying Agent that remains unclaimed at the end of two years after the amount is due to Holders shall be repaid to the Company, subject to any applicable abandoned property laws. After

such two-year period, Holders may look only to the Company for payment and not to the Trustee, any other Paying Agent or anyone else. The Company may also arrange for additional payment offices, and may cancel

or change these offices, including any use of the Trustee’s Corporate Trust Office. The Company may appoint and change the Paying Agent without prior notice to the Holders.

SECTION 2.04. Interest. Interest on the Notes shall accrue at the rate of 5.875% per annum. Interest on the Notes shall

accrue from June 8, 2026 or the most recent Interest Payment Date to which interest was paid or duly provided for. Interest on the Notes shall be payable in cash semiannually in arrears on June 15 and December 15, commencing on

December 15, 2026 (each an “Interest Payment Date”), to the Holders in whose names the Notes are registered at the close of business on the June 1 and December 1, as the case may be, immediately preceding such Interest

Payment Date (whether or not a Business Day, each a “Regular Record Date”). Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve

30-day months.

SECTION 2.05. No Sinking Fund. The provisions of Article XII of

the Base Indenture shall not be applicable to the Notes.

ARTICLE III

ADDITIONAL COVENANTS

addition to the covenants set forth in Article X of the Base Indenture, the Company also covenants and agrees for the benefit of Notes, but not Securities of any other series, as follows:

SECTION 3.01. Limitations on Liens. The Company shall not, and will not permit any of its Domestic Subsidiaries, directly

or indirectly, to issue, assume or guarantee any Debt if that Debt is secured by any Lien upon any Principal Property (or portion thereof) of the Company or of any Domestic Subsidiary of the Company or any shares of stock or Debt of any Domestic

Subsidiary, whether owned on September 14, 2021 or thereafter acquired, without effectively securing the Notes equally and ratably with that Debt, so long as such Debt is so secured. The foregoing restriction does not apply to:

(i) Liens on any property acquired, constructed or improved by the Company or any Domestic Subsidiary of the Company after

September 14, 2021, which are created or assumed contemporaneously with or within three years after its acquisition, or completion of construction or improvement (or within six months thereafter pursuant to a firm commitment for financing

arrangements entered into within that three-year period) to secure or provide for the payment of the Purchase Price or cost thereof, or Liens existing on any property at the time of its acquisition;

(ii) Liens existing on any property, shares of stock or indebtedness acquired from a Person merged with or into the Company or

a Domestic Subsidiary of the Company after September 14, 2021;

(iii) with respect to any corporation that becomes a

Domestic Subsidiary of the Company after September 14, 2021, Liens on property of, or shares of stock or indebtedness issued by, any such corporation existing at the time it becomes a Domestic Subsidiary and not incurred in connection with or

in anticipation of such corporation becoming a Domestic Subsidiary;

(iv) Liens to secure Debt of a Domestic Subsidiary

owed to the Company or Debt of one of the Domestic Subsidiaries of the Company owed to another Domestic Subsidiary of the Company;

(v) Liens in favor of governmental bodies to secure partial, progress, advance or other payments pursuant to any contract or

statute;

(vi) any Lien existing on September 14, 2021; or

(vii) Liens for the sole purpose of extending, renewing or replacing Debt, in whole or in part, secured by any Lien referred to

in the foregoing clauses (i) to (vi), inclusive; provided, however, that the principal amount of Debt secured by that Lien shall not exceed the principal amount of Debt so secured at the time of such extension, renewal or

replacement, and that such extension, renewal or replacement shall be limited to the property that secured the Lien so extended, renewed or replaced (plus improvements on such property).

The limitation on Liens described in this Section 3.01 shall not apply to the issuance, assumption or guarantee by the Company or any

Domestic Subsidiary of the Company of Debt secured by a Lien which would otherwise be subject to the foregoing restrictions up to an aggregate amount which, together with all other Debt of the Company and of the Domestic Subsidiaries of the Company

secured by Liens (not including Liens permitted under the foregoing exceptions) and the Attributable Debt with respect to Sale and Leaseback Transactions existing at that time (other than Sale and Leaseback Transactions in which the property

involved would have been permitted to be subject to a Lien under clause (i) above), does not exceed 10% of Consolidated Net Tangible Assets.

SECTION 3.02. Limitations on Sale and Leaseback Transactions. The Company and the Domestic Subsidiaries of the Company

are prohibited from entering into Sale and Leaseback Transactions unless:

(i) the Company or such Domestic Subsidiary of

the Company would be entitled to incur Debt secured by a Lien on the Principal Property to be leased without equally and ratably securing the Notes, pursuant to clauses (i) - (vii) under Section 3.01 above; or the Attributable Debt

with respect thereto would be an amount permitted under the last paragraph of Section 3.01 above; or

(ii) the Company

or such Domestic Subsidiary of the Company shall, within 180 days of the effective date of any such arrangement, apply an amount equal to the proceeds from such Sale and Leaseback Transaction to the payment or other retirement of Debt that ranks

senior to or equal with the Notes (other than, in either case, Debt owed by the Company or any Subsidiary), or to the purchase of other Principal Property.

SECTION 3.03. Limitations on Guarantees. The Company and the Domestic Subsidiaries of the Company are prohibited from

entering into any agreement pursuant to which any such Domestic Subsidiary of the Company guarantees the payment of Debt incurred by the Company without providing that the Notes be equally and ratably guaranteed by such Domestic Subsidiary of the

Company.

ARTICLE IV

SECTION 4.01. Optional Redemption. On and after June 15, 2029, the Company may redeem all or a part of the Notes,

Year

Redemption

Price

2031 and thereafter

100.000

At any time prior to June 15, 2029, the Company may redeem on any one or more occasions up to 35.0% of

the aggregate principal amount of the Notes (calculated after giving effect to any issuance of additional Notes), upon not less than 15 nor more than 60 days’ prior notice to Holders as provided under Section 1104 of the Base Indenture,

at a redemption price of 105.875% of the principal amount thereof, plus accrued and unpaid interest to (but not including) the Redemption Date, with the net cash proceeds of one or more Equity Offerings; provided, however, that

(1) at least 65.0% of the original aggregate principal amount of Notes (calculated after giving effect to any issuance of additional Notes) remain outstanding immediately after the occurrence of each such redemption and (2) the redemption

occurs within 180 days of the consummation of any such Equity Offering.

At any time prior to June 15, 2029, the Company may redeem

all or a part of the Notes, upon not less than 15 nor more than 60 days’ prior notice to Holders as provided under Section 1104 of the Base Indenture, at a redemption price equal to 100% of the principal amount of the Notes to be

redeemed, plus the Applicable Premium as of, and accrued and unpaid interest to (but not including), the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the Notes on the relevant

interest payment date).

For purposes of determining the optional redemption price, the following definitions are applicable:

“Applicable Premium” means, with respect to the Notes at the Redemption Date, the greater of (i) 1% of the principal amount of the

Notes and (ii) the excess (if any) of (A) the present value at the Redemption Date of (1) the redemption price of such Notes on June 15, 2029 (such redemption price being set forth in the first paragraph in this

Section 4.01) plus (2) all required remaining scheduled interest payments due on the Notes through June 15, 2029 (but excluding accrued and unpaid interest to the Redemption Date), computed using a discount rate equal to the Treasury

Rate plus 0.50% over (B) the principal amount of the Notes outstanding on the Redemption Date. The Trustee shall have no obligation to calculate or verify the calculation of the Applicable Premium or of any component thereof.

“Comparable Treasury Issue” means the United States Treasury security selected

by an Independent Investment Banker as having a maturity comparable to the remaining term (the “Remaining Life”) of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial

practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes (assuming for the purposes of this definition, for the avoidance of doubt, that the Notes matured on June 15, 2029).

“Comparable Treasury Price” means, with respect to any Redemption Date, the average of the Reference Treasury Dealer Quotations

obtained by the Company for that Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or, if the Company is unable to obtain at least four such Reference Treasury Dealer Quotations, the average of all

Reference Treasury Dealer Quotations obtained by the Company.

“Disqualified Stock” means, for the Notes, with respect to any

Person, any capital stock of such Person which, by its terms, or by the terms of any security into which it is convertible or for which it is putable or exchangeable, or upon the happening of any event, matures or is mandatorily redeemable, other

than as a result of a change of control or asset sale, pursuant to a sinking fund obligation or otherwise, or is redeemable at the option of the holder thereof, other than as a result of a change of control or asset sale, in whole or in part, in

each case prior to the date 91 days after the earlier of the maturity date of the Notes or the date the Notes are no longer outstanding; provided that if such capital stock is issued pursuant to any plan for the benefit of employees of the

Company or its Subsidiaries or by any such plan to such employees, such capital stock shall not constitute Disqualified Stock solely because it may be required to be repurchased by the Company or its Subsidiaries in order to satisfy applicable

statutory or regulatory obligations.

“Equity Offering” means any public or private sale of common shares or preferred shares

of the Company (excluding Disqualified Stock), other than (a) public offerings with respect to the Company’s common shares registered on Form S-8 and (b) any sales to the Company or any of its

Subsidiaries.

“Independent Investment Banker” means Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC and their

respective successors, as selected by the Company or, if such firms are unwilling or unable to select the applicable Comparable Treasury Issue or the applicable ratings scale for any Substitute Rating Agency, an independent investment banking

institution of national standing appointed by the Company.

“Reference Treasury Dealer” means Goldman Sachs & Co. LLC

and its successors, and three other independent investment banking institutions of national standing appointed by the Company (each, a “Primary Treasury Dealer”); provided, however, that if any of the foregoing shall cease

to be a Primary Treasury Dealer, the Company shall substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer

Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date for the Notes to be redeemed, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue, expressed in each

case as a percentage of its principal amount, quoted in writing to the Independent Investment Banker by the Reference Treasury Dealer at 3:30 p.m., New York City time, on the third business day preceding the Redemption Date.

“Treasury Rate” means, with respect to any Redemption Date, (i) the yield,

under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “Selected Interest Rates (Daily) – H.15” or any successor publication which

is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,”

for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Remaining Life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be

determined and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounded to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the

calculation date or does not contain such yields, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its

principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding such Redemption Date. For the avoidance of any doubt, the Trustee shall have no obligation

to calculate or verify the calculation of the Treasury Rate.

SECTION 4.02. Purchase of Notes Upon a Change of Control

Repurchase Event. If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem the Notes as described under Section 4.01 above, the Company will be required to make an offer to each Holder of the

Notes to repurchase all or any part (in minimum principal amounts of $2,000 and in integral multiples of $1,000 in excess thereof) of that Holder’s Notes at a repurchase price (the “Purchase Price”) in cash equal to 101% of

the aggregate principal amount of the Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to, but not including, the date of repurchase. Within 30 days following any Change of Control Repurchase Event or, at the

Company’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Company will mail or send a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that

constitute or may constitute the Change of Control Repurchase Event and offering to repurchase the Notes on the payment date specified in the notice (the “Repurchase Date”), which date will be no earlier than 30 days and no later

than 60 days from the date such notice is mailed or sent. The notice shall, if mailed or sent prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on a Change of Control Repurchase Event

occurring on or prior to the payment date specified in the notice. The Company will comply with the requirements of Rule 14e-1 under 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 Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the

Change of Control Repurchase Event provisions of the Notes, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached the Company’s obligations under the Change of Control Repurchase

Event provisions of the Notes by virtue of such conflict. The Trustee shall have no obligation to independently determine or verify if any Change of Control has occurred, nor any obligation to independently determine or verify if a Change of Control

Repurchase Event has occurred or verify that the Company has complied with its obligations under this Section 4.02.

On the Repurchase Date following a Change of Control Repurchase Event, the Company will, to

the extent lawful:

(i) accept for payment all the Notes or portions of the Notes properly tendered pursuant to the

Company’s offer;

(ii) deposit with the Paying Agent an amount equal to the aggregate Purchase Price in respect of

all the Notes or portions of the Notes properly tendered; and

(iii) 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 being purchased by the Company.

The Paying Agent will promptly deliver to each Holder of Notes properly tendered, the Purchase Price for the Notes, and the Trustee will

promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered.

The Company will not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase 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 Company and such third party purchases all Notes properly tendered and not withdrawn under its offer.

For purposes hereof, the following definitions are applicable:

“Change of Control” means the occurrence of any one of the following:

(i) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or

consolidation), in one or a series of related transactions, of all or substantially all of the assets of the Company and its Subsidiaries taken as a whole to any Person (including any “person” (as that term is used in

Section 13(d)(3) of the Exchange Act)) other than to the Company or one of its Subsidiaries;

(ii) the consummation of

any transaction (including, without limitation, any merger or consolidation) the result of which is that any Person (including any “person” (as that term is used in Section 13(d)(3) of the Exchange Act)) becomes the

“beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of

the Company, measured by voting power rather than number of shares;

(iii) the Company consolidates with, or merges with or

into, any Person, or any Person consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of the Company or such other Person is converted into or exchanged for

cash, securities or other property, other than any such transaction where the shares of the Voting Stock of the Company outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting

Stock of the surviving Person immediately after giving effect to such transaction; or

(iv) the adoption of a plan relating to the liquidation or dissolution of

the Company.

“Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Ratings

Event.

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor

Rating Categories of Moody’s), a rating of BBB- or better by S&P (or its equivalent under any successor Rating Categories of S&P) and the equivalent Investment Grade credit rating from any

additional Rating Agency or Rating Agencies selected by the Company.

“Moody’s” means Moody’s Investors

Service, Inc., and its successors.

“Rating Agency” means (1) each of Moody’s and S&P and (2) if

either of Moody’s or S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of the control of the Company, a Substitute Rating Agency thereof.

“Rating Category” means (i) with respect to S&P, any of the following categories: BBB, BB, B, CCC, CC, C and D (or

equivalent successor categories); (ii) with respect to Moody’s, any of the following categories: Baa, Ba, B, Caa, Ca, C and D (or equivalent successor categories); and (iii) the equivalent of any such category of S&P or Moody’s

used by another Rating Agency. In determining whether the rating of any Notes has decreased by one or more gradations, gradations within Rating Categories (+ and - for S&P; 1, 2 and 3 for Moody’s; or the equivalent gradations for

another Rating Agency) shall be taken into account (e.g., with respect to S&P, a decline in a rating from BB+ to BB, as well as from BB- to B+, will constitute a decrease of one gradation).

6.01. Ratification of Base Indenture. The Base Indenture, as heretofore supplemented and as supplemented by this Supplemental Indenture, is in all respects ratified and confirmed, and this Supplemental Indenture shall be deemed

part of the Base Indenture in the manner and to the extent herein and therein provided. Reference to this Supplemental Indenture need not be made in the Indenture or any other instrument or document executed in connection therewith, or in any

certificate, letter or communication issued or made pursuant to, or with respect to, the Indenture, any reference in any of such items to the Indenture being sufficient to refer to the Indenture as amended hereby.

SECTION 6.02. Trust Indenture Act Controls. If any provision hereof limits, qualifies or conflicts with the duties

imposed by Section 310 through 317 of the Trust Indenture Act, the imposed duties shall control.

SECTION 6.03. Conflict

with Indenture. To the extent not expressly amended or modified by this Supplemental Indenture, the Base Indenture, as heretofore supplemented, shall remain in full force and effect. If any provision of this Supplemental Indenture relating

to the Notes is inconsistent with any provision of the Base Indenture, as heretofore supplemented, the provision of this Supplemental Indenture shall control.

SECTION 6.04. GOVERNING LAW AND WAIVER OF JURY TRIAL. THIS SUPPLEMENTAL INDENTURE AND THE NOTES SHALL BE GOVERNED BY, AND

CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. EACH OF THE COMPANY AND THE TRUSTEE HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR

instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. This Supplemental Indenture shall be valid,

binding, and enforceable against a party when executed and delivered by an authorized individual on behalf of the party by means of (i) an original manual signature; (ii) a faxed, scanned, or photocopied manual signature; or (iii) any

other electronic signature permitted by the federal Electronic Signatures in Global and National Commerce Act, state enactments of the Uniform Electronic Transactions Act, and/or any other relevant electronic signatures law, including any relevant

electronic signature, of any other party and shall have no duty to investigate, confirm or otherwise verify the validity or authenticity thereof. This Supplemental Indenture may be executed in any number of counterparts, each of which shall be

2. Indenture.

This Global Security is one of a duly authorized issue of securities of the Company (herein called the “Notes”) issued under

the Indenture, dated as of September 14, 2021 (the “Base Indenture”), between the Company and Computershare Trust Company, N.A., as successor trustee to Wells Fargo Bank, National Association, as Trustee (the “Trustee”), as

supplemented by the Third Supplemental Indenture, dated as of June 8, 2026 (the “Supplemental Indenture”, and together with the Base Indenture as so supplemented, the “Indenture”), between the Company and the Trustee.

Capitalized terms used herein are used as defined in the Indenture unless otherwise indicated. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are

subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the

terms of the Indenture, the terms of the Indenture will control.

The Notes are general unsecured obligations of the Company. The

Indenture limits the original aggregate principal amount of the Notes to $450,000,000 but additional Notes may be issued pursuant to the Indenture, and the originally issued Notes and all such additional Notes vote together for all purposes as a

single class.

3. Redemption and Repurchase; Discharge Prior to Redemption or Maturity.

This Note is subject to redemption by the Company at any time, as further described in the Indenture. This Note is subject to repurchase by

the Company at the option of the holder upon the occurrence of a Change of Control Repurchase Event (as defined in the Supplemental Indenture). There is no sinking fund or mandatory redemption applicable to this Note.

If the Company deposits with the Trustee money or U.S. Government Securities sufficient to pay the then Outstanding principal of, premium, if

4. Registered Form; Denominations; Transfer; Exchange.

The Notes are in registered form without coupons in denominations of $2,000 principal amount and any multiple of $1,000 in excess thereof. A

Holder may register the transfer or exchange of Notes in accordance with the Indenture. The Company or Security Registrar may require a Holder to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law

or permitted by the Indenture. Pursuant to the Indenture, there are certain periods during which the Company will not be required to issue, register the transfer of or exchange any Note or certain portions of a Note.

5. Defaults and Remedies.

If an Event

of Default (other than certain bankruptcy defaults), as defined in the Indenture, occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Notes then Outstanding may declare all the Notes to be due and payable.

If certain bankruptcy defaults with respect to the Company occur and are continuing, the Notes automatically become due and payable. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require

indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the Notes then Outstanding may direct the Trustee in its exercise of remedies.

6. Amendment and Waiver.

Subject to

certain exceptions, the Indenture and the Notes may be amended, or default may be waived, with the consent of the Holders of a majority in principal amount of the Outstanding Notes. Without notice to or the consent of any Holder, the Company and the

Trustee may amend or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency.

ATI Inc.

2021 McKinney Avenue, Suite 1100

Dallas, Texas 75201

Ladies and Gentlemen:

We have acted as

transaction counsel to ATI Inc., a Delaware corporation (the “Company”), in connection with the issuance and sale by the Company of $450,000,000 aggregate principal amount of its 5.875% Notes due 2033 (the “Notes”), under the

Indenture (as defined below), pursuant to the Underwriting Agreement, dated June 3, 2026 (the “Underwriting Agreement”), between the Company and Goldman Sachs & Co. LLC, as representative of the several underwriters listed

on Schedule I thereto (collectively, the “Underwriters”). The Notes are being offered and sold to the Underwriters in an offering registered under the Securities Act of 1933, as amended (the “Securities Act”).

The following documents are referred to collectively in this opinion letter as the “Transaction Documents”:

The Underwriting Agreement;

The Indenture, dated as of September 14, 2021, between the Company and Computershare Trust Company, N.A.,

as successor trustee to Wells Fargo Bank, National Association, as trustee (the “Trustee”), as supplemented by the Third Supplemental Indenture, dated as of June 8, 2026, between the Company and the Trustee (the “Third

Supplemental Indenture”) (as so supplemented, the “Indenture”); and

A specimen of the Notes attached as Exhibit A to the Third Supplemental Indenture.

In connection with rendering the opinions set forth below, we have examined (i) the Registration Statement on Form S-3 (File No. 333-277308) (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) on February 23,

2024; (ii) the base prospectus, dated February 23, 2024, forming a part of the Registration Statement (the “Base Prospectus”); (iii) the preliminary prospectus supplement, dated June 3, 2026, relating to the Notes, as filed by

the Company with the Commission on June 3, 2026 pursuant to Rule

424(b) under the Securities Act; (iv) the Final Term Sheet relating to the Notes, as filed by the Company with the Commission on June 3, 2026 pursuant to Rule 433 under the Securities

Act; (v) the final prospectus supplement, dated June 3, 2026, reflecting the final terms of the Notes and the terms of the offering thereof, as filed by the Company with the Commission on June 4, 2026 pursuant to Rule 424(b) under the

Securities Act (together with the Base Prospectus, the “Prospectus”); (vi) the Transaction Documents; (vii) the Company’s Restated Certificate of Incorporation, as amended, as filed with the Commission and the Company’s

Fifth Amended and Restated Bylaws dated as of May 16, 2025; (viii) a copy of the resolutions adopted by the Board of Directors of the Company on February 22, 2024, relating to the filing of the Registration Statement; and (ix) a copy

of the resolutions adopted by the Board of Directors of the Company on May 12, 2026, relating to the issuance and sale of the Notes by the Company. We also have made such investigation of law as we have deemed appropriate.

For the purposes of this opinion letter, we have made the assumptions that are customary in opinion letters of this kind, including that

(i) each document submitted to us is accurate and complete; (ii) each such document that is an original is authentic; (iii) each such document that is a copy conforms to an authentic original; and (iv) all signatures on each such

document are genuine. We also have assumed for purposes of this opinion letter (i) the legal capacity of natural persons; (ii) that each party to each of the Transaction Documents has the legal capacity or authority and has satisfied all

legal requirements that are applicable to that party to the extent necessary to make each Transaction Document to which it is a party enforceable against it; (iii) that each party to the Transaction Documents complied with all state and federal

statutes, rules and regulations applicable to such party arising out of the transactions set forth in such Transaction Document; (iv) that there are no documents or agreements between any of the parties to the Transaction Documents that have

not been provided to us and that are not listed in this opinion letter that could affect any of the opinions expressed in this opinion letter and no undisclosed modifications, waivers or amendments (whether written or oral) to any agreements

reviewed by us; (v) none of the Underwriters is an interested stockholder (within the meaning of Section 203(c) of the General Corporation Law of the State of Delaware (the “DGCL”)) of the Company; and (vi) there are no

contracts with one or more current or prospective stockholders of the Company (or one or more beneficial owners of stock of the Company), in its or their capacity as such, within the meaning of Section 122(18) of the DGCL. We have not verified

any of the foregoing assumptions.

The opinions expressed in this opinion letter are limited to (i) solely with respect to the

opinion in clause (a) in the paragraph below, the DGCL and (ii) solely with respect to the opinion in clause (b) in the paragraph below, the law of the State of New York, other than its law relating to choice of law (other than

Sections 5-1401 and 5-1402 of the General Obligations Law of the State of New York). We are not opining on, and we assume no responsibility for, the applicability to or

effect on any of the matters covered herein of any other laws, the laws of any county, municipality or other political subdivision or local governmental agency or authority.

ATI Inc.

Based on and subject to the foregoing and to the additional qualifications and other matters

set forth below, it is our opinion that the Notes (a) have been duly authorized, executed, and delivered by the Company and (b) when authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the

Underwriters pursuant to the Underwriting Agreement, will constitute valid and binding obligations of the Company, entitled to the benefits set forth in the Indenture (subject to the effect of applicable bankruptcy, insolvency, orderly liquidation

or resolution, fraudulent transfer and conveyance, preference, reorganization, receivership, conservatorship, moratorium, and other similar laws affecting the rights and remedies of creditors generally, and to the effects of general principles of

equity, whether considered in a proceeding at law or equity, including but not limited to principles limiting the availability of specific performance and injunctive relief, and concepts of materiality, reasonableness, good faith, and fair dealing).

In addition, we express no opinion as to any provision in the Transaction Documents: (i) that purports to release, exculpate, or

exempt a party from, or require indemnification or contribution of a party for, liability for its own negligence or misconduct; (ii) that purports to allow any party to unreasonably interfere in the conduct of the business of another party;

(iii) the effect of which is governed by the law of a jurisdiction other than the State of New York, the DGCL, or the applicable federal securities laws of the United States; (iv) that purports to require any party to pay any amounts due

to another party without a reasonable accounting of the sums purported to be due; (v) that purports to prohibit the assignment of rights that may be assigned pursuant to applicable law regardless of an agreement not to assign such rights;

(vi) that purports to require that amendments to any agreement be in writing; (vii) relating to powers of attorney, severability or set-off; (viii) that purports to restrict access exclusively

to any particular courts; or (ix) providing that decisions by a party are conclusive or may be made in its sole discretion.

This

opinion is limited to the matters stated in this letter, and no opinions may be implied or inferred beyond the matters expressly stated in this letter. This opinion is being given as of the date hereof and we assume no obligation to update or

supplement any of our opinions to reflect any changes of law or fact that may occur.

We hereby consent to the filing of this opinion with

the Commission as an exhibit to the Company’s Current Report on Form 8-K, the incorporation by reference of this opinion into the Registration Statement and the reference to this firm under the heading

“Legal Matters” in the Prospectus forming a part thereof. In giving this consent, we do not thereby admit that we are experts with respect to any part of the Registration Statement or the Prospectus within the

meaning of the term “expert” as used in Section 11 of the Securities Act or the rules and regulations promulgated thereunder by the Commission, nor do we admit that we are within

the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.
