Ladies and Gentlemen:

(“BofA”) and each of the other Underwriters named in Schedule A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 9 hereof), for whom BofA is acting as representative (in such capacity, the “Representative”), with respect to the issue and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amounts set forth in Schedule A of $850,000,000 aggregate principal amount of the Company’s 6.125% Senior Notes due 2029 (the “Notes”). The Notes are to be issued pursuant to an indenture to be dated as of April 9, 2024 (the “Base Indenture”) among the Company and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the second supplemental indenture to be dated as of September 17, 2024 (the “Second Supplemental Indenture” and, the Base Indenture as supplemented by the Second Supplemental Indenture, the “Indenture”) among the Company, the Subsidiary Guarantors (as defined below) and the Trustee. The Notes will be unconditionally guaranteed by those certain wholly-owned subsidiaries of the Company identified on the signature pages hereto (the “Subsidiary Guarantors”) which will guarantee, pursuant to guarantees included in the Indenture (the “Subsidiary Guarantees”), the interest and other amounts payable on the Notes. As used herein the term “Securities” shall include the Notes and the Subsidiary Guarantees.

The Company has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (No. 333-277326), including a related base prospectus, relating to the registration of debt and common stock of the Company (the “Shelf Securities”), including the Securities, which registration statement became effective upon filing under Rule 462(e) of the rules and regulations of the Commission (the “1933 Act Regulations”) pursuant to the Securities Act of 1933, as amended (the “1933 Act”). Such registration statement, at any given time, including the amendments thereto to such time, the exhibits and any schedules thereto at such time, the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act at such time and the documents otherwise deemed to be a part thereof or included therein by 1933 Act Regulations, including any required information deemed to be a part thereof pursuant to Rule 430B (“Rule 430B”) of the 1933 Act Regulations is herein called the “Registration Statement” and the related prospectus covering the Shelf Securities included in the Registration Statement at any given time, including the amendments thereto at such time, is herein called the “Base Prospectus.” The Registration Statement at the time it originally became effective is herein called the “Original Registration Statement.”

The Company has prepared, filed and delivered to each Underwriter, copies of a preliminary prospectus supplement dated September 3, 2024 in accordance with the provisions of Rule 430B and paragraph (b) of Rule 424 (“Rule 424(b)”) of the 1933 Act Regulations (together with the Base Prospectus (to the extent not superseded or modified), the “Preliminary Prospectus”), and has provided to each Underwriter the information set forth on Schedule C hereto (the “Pricing Supplement”), each for use by the Underwriters in connection with its solicitation of offers to purchase the Securities. The Preliminary Prospectus and the Pricing Supplement, together with the other Issuer Free Writing Prospectuses (as defined below), if any, identified on Schedule B-2 hereto and any other free writing prospectus (as defined below) that the parties hereto shall hereafter expressly agree in writing to treat as part of the Pricing Disclosure Package, are herein referred to as the “Pricing Disclosure Package”. All references herein to the terms “Pricing Disclosure Package” and “Prospectus” (as defined below) shall be deemed to mean and include all information filed under the Securities Exchange Act of 1934, as amended (the “1934 Act”) or the rules and regulations of the Commission under the 1934 Act (the “1934 Act Regulations”), prior to the Applicable Time and incorporated by reference in the Pricing Disclosure Package. “Applicable Time” means 4:40 p.m. (New York City time) on the date of this Agreement or such other time as agreed by the Company and the Representative.

Promptly after the Applicable Time, the Company will prepare and deliver to each Underwriter a final prospectus supplement dated the date hereof. The Base Prospectus (to the extent not superseded or modified) together with the final prospectus supplement in the form first furnished to the Underwriters for use in connection with the offering of the Securities is herein referred to as the “Prospectus”.

For purposes of this underwriting agreement (this “Agreement”), “free writing prospectus” has the meaning set forth in Rule 405 of the 1933 Act Regulations and “Issuer Free Writing Prospectus” means any issuer free writing prospectus, as defined in Rule 433 of the 1933 Act Regulations, relating to the Securities in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, the Pricing Disclosure Package and the Prospectus (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which are incorporated by reference in or otherwise deemed by the 1933 Act Regulations to be a part of or included in the applicable document; and all references herein to the terms “amend,” “amendment,” or “supplement” with respect to the Registration Statement, the Base Prospectus, the Preliminary Prospectus, any free writing prospectus or the Prospectus shall be deemed to mean and include all information filed under the 1934 Act or the 1934 Act Regulations on or before such time and incorporated by reference therein.

SECTION 1. Representations and Warranties by the Company and Subsidiary Guarantors. The Company and the Subsidiary Guarantors jointly and severally represent and warrant to each Underwriter as of the date hereof, the Applicable Time and as of the Closing Time as follows (references in this Section 1 to the Prospectus shall apply only in the case of representations and warranties made as of the Closing Time):

Any offer that is a written communication relating to the Securities made prior to the filing of the Original Registration Statement by the Company or any person acting on its behalf (within the meaning, for this paragraph only, of Rule 163(c) of the 1933 Act Regulations) has been filed with the Commission in accordance with the exemption provided by Rule 163 and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the 1933 Act provided by Rule 163.

SECTION 6. Indemnification.

(a) Indemnification of Underwriters. The Company and the Subsidiary Guarantors, jointly and severally, agree to indemnify and hold harmless (i) each Underwriter, (ii) each person, if any, who controls any Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act and (iii) the respective officers, directors, partners, employees, representatives, affiliates and agents of any Underwriter or person referenced in clause (ii) from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim, which expenses shall be paid as incurred) arising out of or based upon (x) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof (including any information deemed to be a part thereof pursuant to Rule 430B or Rule 430C of the 1933 Act Regulations) or 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 (y) or any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus, any preliminary prospectus (including the Preliminary Prospectus), the Pricing Disclosure Package or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or 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, in the light of the circumstances under which they were made, not misleading, except, in each case, insofar as such losses, claims, damages or liabilities arise out of or based upon any such untrue statement or omission or alleged untrue statement or omission 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 an Underwriter consists of the information described in Section 6(f)).

-21-

(b) Indemnification of Company and the Subsidiary Guarantors. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless (i) the Company, its directors, its officers who signed the Registration Statement and each Subsidiary Guarantor and each of the Subsidiary Guarantor’s directors and officers who signed the Registration Statement, (ii) each person, if any, who controls the Company and any Subsidiary Guarantor within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act and (iii) the respective officers, directors, partners, employees, representatives, affiliates and agents of the Company, any Subsidiary Guarantor or person referenced in clause (ii) to the same extent as the foregoing indemnity in Section 6(a) from the Company to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus (including the Preliminary Prospectus), the Pricing Disclosure Package or the Prospectus or any amendments or supplements thereto (it being understood and agreed that the only such information furnished by an Underwriter consists of the information described as such in Section 6(f)).

(c) Indemnification Procedures. In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either Section 6(a) or 6(b), such person (the “Indemnified Party”) shall promptly notify the person from whom such indemnity may be sought (the “Indemnifying Party”) in writing (provided that failure to so notify an Indemnifying Party shall not relieve such Indemnifying Party from any liability under Section 6(a) or 6(b) to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement) and the Indemnifying Party, upon request of the Indemnified Party, shall retain counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party and any others the Indemnifying Party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any Indemnified Party 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 Party, unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed in writing to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or different legal defenses available to them. It is understood that the Indemnifying Party shall not, in respect of the legal expenses of any Indemnified Party in connection with any proceeding or related proceedings 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 such Indemnified Parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representative, in the case of parties indemnified pursuant to Section 6(a) above, and by the Company, in the case of parties indemnified pursuant to Section 6(b) above. The Indemnifying Party 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 from and against any loss or liability 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 the first and second sentences of this paragraph, 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 90 days after receipt by such Indemnifying Party of the aforesaid

-22-

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 of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such proceeding and 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 Party.

(d) Contribution. To the extent the indemnification provided for in Section 6(a) or 6(b) is unavailable to an Indemnified Party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnified Party under such paragraph, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party 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 and the Subsidiary Guarantors on the one hand and the Underwriters on the other hand from the offering of the Securities, or (ii) if the allocation provided by Section 6(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in Section 6(d)(i) above but also the relative fault of the Company and the Subsidiary Guarantors on the one hand and of the Underwriters on the other hand 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 and the Subsidiary Guarantors on the one hand and the Underwriters on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of such Securities (before deducting expenses) received by the Company and the total underwriting discounts or commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Price to Public of the Notes. The relative fault of the Company and the Subsidiary Guarantors on the one hand and the Underwriters on the other hand 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 and the Subsidiary Guarantors or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 6 are several in proportion to the respective principal amounts of Notes they have purchased hereunder, and not joint.

(e) The Company, the Subsidiary Guarantors and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 6 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 Section 6(d). The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6, no Underwriter shall be required to contribute any amount in excess of the amount by which the underwriting discounts or commissions applicable to 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 1933 Act) shall be entitled to contribution from any person who was not liable for any such fraudulent misrepresentation. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Party at law or in equity. The obligations of the Underwriters to contribute pursuant to this Section 6 are several in proportion to their respective purchase obligations hereunder, and not joint.

-23-

(f) It is understood and agreed that the only information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: paragraph three (first sentence only), paragraph eight (third sentence only) and paragraph nine (first, second and third sentences only) under the caption “Underwriting”.

SECTION 7. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements, including indemnity and contribution provisions, contained in this Agreement, or contained in certificates of officers of the Company and the Subsidiary Guarantors submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Company, and shall survive the termination of this Agreement and the delivery of the Securities to the Underwriters.

SECTION 8. Termination of Agreement.

(a) Termination; General. This Agreement shall be subject to termination by notice given by the Representative to the Company, if (a) after the execution and delivery of this Agreement and prior to the Closing Time (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange, NYSE Amex Equities or the FINRA, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over the counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities, (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in the reasonable judgment of the Representative, is material and adverse or (v) there has been, since the Applicable Time or since the respective dates as of which information is given in the Prospectus or the Pricing Disclosure Package, any material adverse change in the condition, financial or otherwise, or in the results of operations, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business and (b) in the case of any of the events specified in Sections 8(a)(i) through 8(a)(v), such event, singly or together with any other such event, makes it, in the sole judgment of the Representative, impracticable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated in the Registration Statement, the Pricing Disclosure Package and the Prospectus.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof. Notwithstanding any such termination, the provisions of Section 6 shall remain in effect.

SECTION 9. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representative shall have the right, within 48 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other Underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 48-hour period, then:

(a) if the number of Defaulted Securities does not exceed 10% of the Notes, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

-24-

(b) if the number of Defaulted Securities exceeds 10% of the Notes, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default. In the event of any such default which does not result in a termination of this Agreement, either the Representative or the Company shall have the right to postpone the Closing Time, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section.

SECTION 10. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to the Representative c/o BofA Securities, Inc., 1540 Broadway, 26th Floor, New York, NY 10036, Attention: High Yield Legal Department with a copy at the same address to: BofA_HY_Legal_Notices@bofa.com, and with a copy to Cahill Gordon & Reindel LLP, 32 Old Slip, New York, NY 10005, attention of James J.

Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the parties hereto and their respective successors and the controlling persons, officers and directors referred to in Section 6 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the parties hereto and their respective successors, and said controlling persons, officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Notes from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 12. Governing Law and Time; Consent to Jurisdiction. This Agreement and any claim, controversy or dispute arising under or related to this Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and to be performed in said State. Specified times of day refer to New York City time unless otherwise expressly provided herein. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby shall be instituted in (i) the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan or (ii) the courts of the State of New York located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court.

SECTION 14. No Fiduciary Responsibility. Each of the Company and the Subsidiary Guarantors acknowledges and agrees that in connection with all aspects of each transaction contemplated by this Agreement (collectively, the “Transactions”), the Company and the Subsidiary Guarantors and each Underwriter and any affiliate through which it may be acting (each, a “Transaction Affiliate”) have an arm’s length business relationship that creates no fiduciary duty on the part of each Underwriter or any Transaction Affiliate and each expressly disclaims any fiduciary relationship with respect to any and all aspects of the Transactions.

SECTION 15. Waiver of Jury Trial. Each of the parties hereto irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

State Tech. §§ 301-309), as amended from time to time, or other applicable law) shall be effective as delivery of a manually executed counterpart thereof), each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

SECTION 17. Compliance with USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub.

(a) 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.

(b) 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.

In determining the Treasury Rate, we 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 September 15, 2026 (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 September 15, 2026 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 Date preceding the Redemption Date H.15 TCM is no longer published, we 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, September 15, 2026, as applicable. If there is no United States Treasury security maturing on September 15, 2026, but there are two or more United States Treasury securities with a maturity date equally distant from September 15, 2026, one with a maturity date preceding September 15, 2026 and one with a maturity date following September 15, 2026, we shall select the United States Treasury security with a maturity date preceding September 15, 2026. If there are two or more United States Treasury securities maturing on September 15, 2026 or two or more United States Treasury securities meeting the criteria of the preceding sentence, we 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 Pari Passu Liens granted pursuant to this provision shall be (A) granted concurrently with the granting of any such Liens, and (B) granted pursuant to instruments, documents and agreements which are no less favorable to the Trustee and the Holders of the Notes than those granted to secure the Existing Senior Notes. In connection with the granting of any such Pari Passu Liens, the Company and each Subsidiary Guarantor shall provide to the Trustee (y) policies of title insurance on customary terms and conditions, to the extent that policies of title insurance on the corresponding property are provided to the Holders of the Existing Senior Notes or their respective trustee (and in an insured amount that bears the same proportion to the principal amount of the outstanding Notes as the insured amount in the policies provided to the holders of the Existing Senior Notes bears to the aggregate outstanding amount of the Existing Senior Notes), and (z) legal opinions and other assurances as the Trustee may reasonably request; and

-12-

(ii) if the Company and the Subsidiary Guarantors become entitled to the release of any Initial Liens securing the Existing Senior Notes and Subsidiary Guarantees related thereto, and provided that no Default or Event of Default has then occurred and remains continuing, the Company and the Subsidiary Guarantors may in their sole discretion request that the collateral agent release any such Lien securing the Notes, the Existing Senior Notes and such other notes and guarantees, and in such circumstances the collateral agent (or the Trustee) shall so release such Initial Liens.

(c) Notwithstanding the foregoing, the Company or any Subsidiary Guarantor may create, assume or suffer to exist Liens not otherwise permitted as described above, provided that at the time of such incurrence, assumption or sufferance, after giving effect to such Lien, the sum of outstanding Indebtedness secured by such Liens (not including Liens permitted under Section 5.1(a) above) plus all Attributable Debt in respect of Sale and Lease-Back Transactions entered into (not including Sale and Lease-Back Transactions permitted under Section 5.2(a) below), measured, in each case, at the time the Lien is incurred, does not exceed 15% of Consolidated Net Tangible Assets and Liens securing Indebtedness in excess of such amount to the extent such Lien is incurred in connection with an extension, renewal, replacement or refinancing of Indebtedness (not to exceed the principal amount of such extended, renewed, replaced or refinanced Indebtedness plus fees, expenses and premium payable thereon) secured by a Lien incurred pursuant to the provisions of this Section 5.1(c) or any previous extension, renewal, replacement or refinancing of any such Indebtedness (which extended, renewed, replaced or refinanced Indebtedness shall, for the avoidance of doubt, thereafter be included in the calculation of such amount), provided that the foregoing shall not apply to any Liens that may at any time secure any of the Existing Senior Notes.

SECTION 5.2. Limitation on Sale and Lease-Back Transactions.

(a) Other than as provided in Section 5.2(b) below, neither the Company nor any Subsidiary Guarantor will enter into any Sale and Lease-Back Transaction, unless either:

(i) the Company or such Subsidiary Guarantor would be entitled, pursuant to the provisions described in clauses (i) through (xii) of Section 5.1(a) above, to create, assume or suffer to exist a Lien on the property to be leased without equally and ratably securing the Notes;

(ii) such Sale and Lease-Back Transaction is executed at the time of, or within 12 months after the latest of, the acquisition, the completion of construction or improvement, or the commencement of commercial operation of the applicable Principal Property;

(iii) an amount equal to the net cash proceeds of such sale is applied within 180 days to the retirement, discharge, repurchase, repayment or prepayment of its Funded Debt; or

(iv) an amount equal to the net cash proceeds of such sale is applied within 180 days to the purchase, construction, development, expansion or improvement of other property.

(b) Notwithstanding the restrictions set forth in Section 5.1 and Section 5.2 (a), the Company or any Subsidiary Guarantor may enter into Sale and Lease-Back Transactions not otherwise permitted as described above, provided that at the time of entering into such Sale and Lease-Back Transaction, after giving effect to such Sale and Lease-Back Transaction, the sum of outstanding Indebtedness secured by Liens (not including Liens permitted under Sections 5.1(a) and 5.1(b) above) plus all Attributable Debt in respect of Sale and Lease-Back Transactions entered into (not including Sale and Lease-Back Transactions permitted under Section 5.2(a) above), measured, in each case, at the time any such Sale and Lease-Back Transaction is entered into, does not exceed 15% of Consolidated Net Tangible Assets and Liens securing Indebtedness in excess of such amount to the extent such Lien is incurred in connection with an extension, renewal, replacement or refinancing of Indebtedness (not to exceed the principal amount of such extended, renewed, replaced or refinanced Indebtedness plus fees,

-13-

expenses and premium payable thereon) secured by a Lien incurred pursuant to the provisions of this Section 5.2(b) or any previous extension, renewal or replacement or refinancing of any such Indebtedness (which extended, renewed, replaced or refinanced Indebtedness shall, for the avoidance of doubt, thereafter be included in the calculation of such amount), provided that the foregoing shall not apply to any Liens that may at any time secure any of the Existing Senior Notes.

SECTION 5.3. Guarantee.

(a) The Company shall (i) cause each domestic Subsidiary of the Company that is a guarantor of Reference Indebtedness (other than MGM Yonkers and any other Subsidiary Guarantor subject to the oversight of the New York State Gaming Commission, unless and until New York Gaming Approval is obtained, and, with respect to MDDC and MDDHC, unless and until New Jersey Gaming Approval is obtained) to become on the Issue Date or, if such Subsidiary was not a guarantor of Reference Indebtedness as of the Issue Date but thereafter becomes a guarantor of Reference Indebtedness (whether or not such Subsidiary is acquired or created after the Issue Date) and is wholly-owned, directly or indirectly, by the Company (a “Wholly-Owned Subsidiary”), at the time such Wholly-Owned Subsidiary guarantees any Reference Indebtedness, a guarantor of the obligations of the Company under this Indenture and the Notes by executing this Indenture (directly, by supplemental indenture or by a joinder agreement, a form of which is attached hereto as Exhibit II) as a Subsidiary Guarantor or by executing a Guarantee pursuant to Section 1102 of the Base Indenture, as supplemented by this Second Supplemental Indenture; provided that any newly created or acquired Subsidiary that requires approval from a Gaming Authority in order to execute and deliver a Guarantee shall not be required to execute and deliver such Guarantee unless and until it receives the required approval from the applicable Gaming Authority, and shall execute and deliver the Guarantee in accordance with the provisions of this Section 5.3(a) upon receipt of approval from the applicable Gaming Authority; and provided further that the provision of a Guarantee by a Wholly-Owned Subsidiary after the Issue Date shall be subject to compliance with any applicable Gaming Laws and the Company agrees that (subject to Section 5.3(b)) it shall not have any such Wholly-Owned Subsidiary become a guarantor of Reference Indebtedness unless it is permitted to give such Guarantee under applicable Gaming Laws); and (ii) deliver to the Trustee an Opinion of Counsel that such Guarantee is the valid, binding and enforceable obligation of such Subsidiary Guarantor, subject to customary exceptions for bankruptcy, fraudulent transfer and equitable principles.

Notwithstanding the foregoing, for the avoidance of doubt with respect to any Subsidiary existing on the Issue Date that has executed this Second Supplemental Indenture as of the Issue Date but is required to obtain regulatory approval from a Gaming Authority in order to guarantee the Company’s obligations under this Second Supplemental Indenture and the Notes (including New York Gaming Approval, with respect to MGM Yonkers, and New Jersey Gaming Approval, with respect to MDDC and MDDHC), such Subsidiary shall not have any liability for, or be subject to any obligation to guarantee, the Company’s obligations under this Second Supplemental Indenture or the Notes unless and until such Subsidiary receives regulatory approval from the applicable Gaming Authority. Upon the receipt of such regulatory approval from the applicable Gaming Authority, such Subsidiary shall immediately and automatically, without any further action by such Subsidiary or by the Company, be and become a Subsidiary Guarantor for all purposes under this Second Supplemental Indenture and the Notes, subject to, without limitation, all liabilities and obligations of Subsidiary Guarantors described under Section 1101 of the Indenture with respect to the Notes.

(b) The actions set forth in Section 5.3(a) hereof shall be taken within 10 days of the time on which any Person is required to become a Subsidiary Guarantor pursuant to such Section 5.3(a), provided that if such Person is not permitted to give a Guarantee under applicable Gaming Laws, then, such 10-day period shall be extended as long as necessary for the Company to, and the Company shall

-14-

continue to use reasonable best efforts to, obtain the requisite approvals for such Guarantee from the applicable Gaming Authority. If any Subsidiary Guarantor no longer guarantees any Reference Indebtedness at any time, then such Subsidiary Guarantor shall be released from its obligations under its Guarantee, and the Trustee shall execute any documents reasonably required in order to evidence the release of such Subsidiary Guarantor from its obligations under its Guarantee upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such conditions to release such Guarantee have been satisfied.

(c) The Company will not permit any newly acquired or created Wholly-Owned Subsidiary to guarantee any Reference Indebtedness without making effective provision for such Wholly-Owned Subsidiary to become a Subsidiary Guarantor under this Indenture (unless such guarantee is not permitted under applicable Gaming Laws and the Company is complying with Section 5.3(b) hereof).

SECTION 5.4. Reports.

(a) Whether or not required by the Commission, so long as any Notes are outstanding, the Company shall furnish to the Trustee within 15 calendar days after the time periods specified in the Commission’s rules and regulations:

(1) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report thereon by the Company’s independent registered public accounting firm; and

(2) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports (it being understood that the availability of such information or report on the Commission’s EDGAR service (or any successor thereto) shall be deemed to satisfy the Company’s obligation to furnish the information or report referenced in clauses (a)(1) and (a)(2) of this Section 5.4 to the Trustee).

(b) In addition, whether or not required by the Commission, the Company will file a copy of all of the information and reports referred to in clauses (1) and (2) above with the Commission for public availability within the time periods specified in the Commission’s rules and regulations (unless the Commission will not accept such a filing) and make such information available to securities analysts and prospective investors upon request.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such reports, information and documents shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely conclusively on the Officer’s Certificate described in Section 1004 of the Base Indenture). The Trustee is under no duty to examine such reports, information or documents to ensure compliance with the provisions of this Second Supplemental Indenture or to ascertain the correctness or accuracy of the information or the statements contained therein. The Trustee is entitled to assume such compliance and correctness unless an Officer of the Trustee is informed in writing otherwise.

(b) default in the payment of principal of (or premium, if any, on) the Notes at their Maturity (upon acceleration, optional or mandatory redemption or otherwise); or

(c) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section 501 specifically dealt with), and continuance of such default or breach for a period of 60 calendar days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the outstanding Notes, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or

(d) the acceleration of the maturity of any Indebtedness of the Company or any Subsidiary Guarantor (other than Non-Recourse Indebtedness), at any time, in an amount in excess of the greater of (i) $250,000,000 and (ii) 5% of Consolidated Net Tangible Assets, if such acceleration is not annulled within 30 calendar days after written notice to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the outstanding Notes; or

(e) entry of final judgments against the Company or any Subsidiary Guarantor which remain undischarged for a period of 60 days, provided that the aggregate of all such judgments exceeds $250,000,000 and judgments exceeding $250,000,000 remain undischarged for 60 calendar days after written notice to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the outstanding Notes; or

If a failure to comply by the Company with Section 5.4 continues for 60 days after the Company receives notice of such failure to comply in accordance with clause (c) of the definition of “Event of Default” (such notice, the “Reports Default Notice”), and is continuing on the 60th day following the Company’s receipt of the Reports Default Notice, the Company will pay liquidated damages to all holders of Notes at a rate per annum equal to 0.25% of the principal amount of the Notes from the 60th day following the Company’s receipt of the Reports Default Notice to but not including the earlier of (x) the 121st day following the Company’s receipt of the Reports Default Notice and (y) the date on which the failure to comply by the Company with Section 5.4 shall have been cured or waived.

If the failure to comply by the Company with Section 5.4 shall not have been cured or waived on or before the 121st day following the Company’s receipt of the Reports Default Notice, then the failure to comply by the Company with Section 5.4 shall on such 121st day constitute an Event of Default. A failure to comply with Section 5.4 automatically shall cease to be continuing and shall be deemed cured at such time as the Company furnishes to the Trustee the applicable information or report (it being understood that the availability of such information or report on the Commission’s EDGAR service (or any successor thereto) shall be deemed to satisfy the Company’s obligation to furnish such information or report to the Trustee).

SATISFACTION AND DISCHARGE

SECTION 8.1. Satisfaction and Discharge.

Article IV of the Base Indenture shall be superseded in its entirety by the following language with respect to, and solely for the benefit of the Holders of the Notes; provided that this Article Eight shall not become part of the terms of any other series of Securities:

Section 402. Application of Trust Money.

Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Notes, and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Company may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee.

Section 403. Applicability of this Article.

Except as otherwise provided in Section 404, the Company may terminate its obligations under the Notes and this Indenture as set forth in Section 404.

Section 404. Defeasance upon Deposit of Moneys or U.S. Government Obligations.

At the Company’s option, either (x) the Company shall be deemed to have been Discharged (as defined below) from its obligations with respect to Notes and the Subsidiary Guarantors shall be deemed to have been discharged from their obligations under their Guarantees in respect of the Notes (“legal defeasance option”) or (y) the Company shall cease to be under any obligation to comply with any term, provision or condition set forth in Article VIII and Section 1004, and Sections 5.1, 5.2 and 5.3 of the Second Supplemental Indenture with respect to Notes and the Subsidiary Guarantors shall cease to be under any obligation to comply with any term, provision or condition set forth in Section 1111 (or comparable provisions of its Guarantee if not set forth in Article XI) with respect to their Guarantees in respect of the Notes (“covenant defeasance option”) at any time after the applicable conditions set forth below have been satisfied:

(e) The Company shall have deposited or caused to be deposited irrevocably with the Trustee as trust funds in trust, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of the Notes (i) money in an amount, or (ii) U.S. Government Obligations (as defined below) which through the payment of interest and principal in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination of items (i) and (ii), sufficient, in the opinion (with respect to items (i) and (ii)) of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge each installment of principal (including any mandatory sinking fund payments) of and premium, if any, and interest on, the outstanding Notes on the dates such installments of interest or principal and premium are due;

-20-

(f) Such deposit shall not cause the Trustee to have a conflicting interest as defined in Section 608 and for purposes of the TIA;

(g) Such deposit will not result in a breach or violation of, or constitute a default under, this Indenture or any other agreement or instrument to which the Company or any Subsidiary Guarantor is a party or by which it is bound;

(i) No Event of Default or Default shall have occurred and be continuing on the date of such deposit and, with respect to the legal defeasance option only, no Event of Default under Section 501(f) or Section 501(g) or event which with the giving of notice or lapse of time, or both, would become an Event of Default under Section 501(f) or Section 501(g) shall have occurred and be continuing on the 91st day after such date;

(j) The Company shall have delivered to the Trustee an Opinion of Counsel or a ruling from the Internal Revenue Service to the effect that the beneficial owners of the Notes will not recognize income, gain or loss for United States federal income tax purposes as a result of such deposit, defeasance or Discharge. Notwithstanding the foregoing, if the Company exercises its covenant defeasance option and an Event of Default under Section 501(f) or Section 501(g) or event which, with the giving of notice or lapse of time, or both, would become an Event of Default under Section 501(f) or Section 501(g) shall have occurred and be continuing on the 91st day after the date of such deposit, the obligations of the Company and the Subsidiary Guarantors referred to under the definition of covenant defeasance option with respect to such Notes shall be reinstated; and

(k) the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions) each stating that all conditions precedent provided for or relating to the legal defeasance or the covenant defeasance, as the case may be, have been complied with.

“Discharged” means that the Company and the Subsidiary Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by, and obligations under, the Notes and the Guarantees in respect of the Notes and to have satisfied all the obligations under this Indenture in respect of the Notes (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except (i) the rights of Holders of Notes to receive, from the trust fund described in clause (a) above, payment of the principal of (and premium, if any) and interest on such Notes when such payments are due, (ii) the Company’s obligations with respect to the Notes under Sections 304, 305, 306, 405 and 1002 and (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder.

“U.S. Government Obligations” means securities that are (i) direct obligations of the United States for the payment of which its full faith and credit is pledged, or (ii) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of the United States the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States, which, in either case under clause (i) or (ii), are not callable or redeemable at the option of the issuer thereof prior to the final Maturity Date of the Notes, and shall also include a depository receipt issued by

-21-

a bank or trust company as custodian with respect to any such U.S. Government Obligation or a specific payment of interest on or principal of any such U.S. Government Obligation held by such custodian for the account of the Holder of a depository receipt; provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the Holder of such depository receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of interest on or principal of the U.S. Government Obligation evidenced by such depository receipt.

Section 405. Deposited Moneys and U.S. Government Obligations to be Held in Trust.

The Company shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 404 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Section 406. Repayment to Company.

The Trustee and any Paying Agent shall promptly pay or return to the Company upon Company Request any moneys or U.S. Government Obligations held by them at any time that are not required for the payment of the principal of (and premium, if any) and interest on the Notes for which money or U.S. Government Obligations have been deposited pursuant to Section 404.

The provisions of the last paragraph of Section 1003 shall apply to any money held by the Trustee or any Paying Agent under this Article that remains unclaimed for two years after the Maturity of any Notes for which money or U.S. Government Obligations have been deposited pursuant to Section 404.

FORM OF REVERSE SIDE OF NOTE

6.125% Senior Note Due 2029

MGM RESORTS INTERNATIONAL, a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at the rate per annum shown above.

The Company shall pay interest semi-annually in arrears on March 15 and September 15 of each year commencing on March 15, 2025. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from September 17, 2024,¹ with respect to this Note. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

The Company shall pay interest (except defaulted interest) on the Notes to the Persons who are registered Holders of Notes at the close of business on the March 1 and September 1 immediately preceding the interest payment date even if Notes are canceled after the record date and on or before the interest payment date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, all payments in respect of this Note (including principal, premium, if any, and interest) must be made by wire transfer of immediately available funds to the accounts specified by the Holder hereof.

Initially, U.S. BANK TRUST COMPANY, NATIONAL ASSOCIATION (the “Trustee”) shall act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent or Registrar without notice to the Holders. The Company or any domestically organized Subsidiary may act as Paying Agent or Registrar.

The Company issued the Notes under an indenture dated as of April 9, 2024 (the “Base Indenture”), as amended by the Second Supplemental Indenture dated as of September 17, 2024 (the “Second Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), among the Company, the Subsidiary Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA. Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of those terms.

The Notes are unsecured senior obligations of the Company. Subject to the conditions set forth in the Indenture, the Company may issue Additional Notes in an unlimited principal amount. This Note is one of the Notes referred to in the Indenture. The Notes include the Initial Notes and the Additional Notes. The Initial Notes and the Additional Notes are treated as a single class of Notes under the Indenture. The Subsidiary Guarantors have, jointly and severally, unconditionally guaranteed the guaranteed obligations on a senior unsecured basis pursuant to the terms of the Indenture.

I-5

(a) On and after September 15, 2026, the Company may on any one or more occasions redeem the Notes, in whole or in part, upon not less than 10 nor more than 60 days’ notice mailed or otherwise delivered to each holder of Notes in accordance with the applicable procedures of DTC, at the redemption prices (expressed as a percentage of principal amount of the Notes to be redeemed) set forth below, plus accrued and unpaid interest on the Notes, if any, to the applicable date of redemption, if redeemed during the twelve-month period beginning on September 15 of each of the years indicated below:

(b) In addition, the Notes are redeemable at the election of the Company, in whole or in part, at any time or from time to time prior to September 15, 2026, at a redemption price (the “Redemption Price”) equal to the greater of:

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

(ii) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the notes matured on September 15, 2026) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points less (b) interest accrued to the date of redemption,

plus, in either of the above cases, accrued and unpaid interest to the Redemption Date on the Notes to be redeemed.

(c) Prior to September 15, 2026, the Company may also on any one or more occasions redeem in the aggregate up to 40% of the aggregate principal amount of the Notes (calculated after giving effect to any issuance of additional notes under the Indenture) with the net cash proceeds of one or more Equity Offerings, upon not less than 10 nor more than 60 days’ notice mailed or otherwise delivered to each Holder in accordance with the applicable procedures of DTC, at a redemption price equal to 106.125% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to the Redemption Date; provided that:

(i) at least 50% of the original aggregate principal amount of the Notes remains outstanding after each such redemption; and

(ii) such redemption occurs within 120 days after the closing of such Equity Offering

(d) Except as described in this paragraph 5, the Notes shall not be redeemable at the Company’s option prior to September 15, 2026.

I-6

Notices of redemption shall be mailed by first-class mail or otherwise delivered at least 10 (unless a shorter notice is acceptable to the Trustee) days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address all in accordance with the Indenture. Any notice to Holders of Notes of a redemption will state, among other things, the redemption price (or how the redemption price will be calculated if not a fixed amount or subject to change) and date. A notice of redemption may provide that the optional redemption described in such notice is conditioned upon the occurrence of certain events before the Redemption Date. Such notice of conditional redemption will be of no effect unless all such conditions to the redemption have occurred before the Redemption Date or have been waived the Company. If any of such events fail to occur and are not waived by the Company, the Company shall be under no obligation to redeem the Notes or pay the Holders any redemption proceeds and the Company’s failure to redeem the Notes shall not be considered a default or an Event of Default. If less than all of the Notes are to be redeemed at any time (other than pursuant to paragraph 5 above) the particular Notes to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the outstanding Notes not previously called for redemption, consistent with the procedures of DTC. On and after the Redemption Date, interest ceases to accrue on Notes or portions of them called for redemption.

In connection with any tender offer or other offer to purchase for all of the Notes, if holders of not less than 90% of the aggregate principal amount of the then outstanding Notes validly tender and do not validly withdraw such Notes in such tender offer and the Company, or any third party making such tender offer in lieu of the Company, purchases all of the Notes validly tendered and not validly withdrawn by such holders, the Company or such third party will have the right, upon not less than 10 nor more than 60 days’ notice following such purchase date, to redeem all Notes that remain outstanding following such purchase at a price equal to the price paid to each other holder in such tender offer, plus, to the extent not included in the tender offer payment, accrued and unpaid interest, if any, thereon, to, but excluding, the date of such redemption.

The Notes are in registered form without coupons in minimum denominations of $2,000 and whole multiples of $1,000. A Holder may transfer or exchange Notes in accordance with the Indenture. Upon any transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate transfer documents and to pay any taxes required by law or permitted by the Indenture. The Registrar shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 calendar days before the day of any selection of Notes for redemption and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

The registered Holder of this Note may be treated as the owner of it for all purposes.

If money for the payment of principal or interest remains unclaimed for two years, the Paying Agent shall pay the money back to the Company at its request, or if then held by the Company or a domestic Subsidiary, shall be discharged from such trust (unless an abandoned property law designates another Person for payment thereof). After any such payment, Holders entitled to the money must look only to the Company for payment thereof, and all liability of the Paying Agent with respect to such money, and all liability of the Company or such permitted Subsidiary as trustee thereof, shall thereupon cease.

I-7

Subject to certain conditions set forth in the Indenture, the Company at any time may terminate some or all of its obligations under the Indenture with respect to the Notes if, among other things, the Company deposits with the Trustee funds for the payment of principal and interest on the Notes to redemption or maturity, as the case may be.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time outstanding. The Indenture also contains provisions, with certain exceptions as therein provided, permitting the Holders of a majority in principal amount of the Notes at the time outstanding, on behalf of the Holders of all such Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. The Indenture also permits certain other amendments, modifications or waivers thereof only with the consent of all affected Holders of the Notes, while certain other amendments or modifications may be made without the consent of any Holders of Notes. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. The right of any Holder of a Note (or such Holder’s duly designated proxy) to participate in any consent required or sought pursuant to any provision of the Indenture (and the obligation of the Company to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of Notes as of a date set by the Company and identified by the Trustee in a notice furnished to Holders of the Notes in accordance with the terms of the Indenture.

Events of Default are set forth in the Indenture. If an Event of Default shall have occurred and be continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding Notes may declare the principal of, premium, if any, and accrued interest on all the Notes to be due and payable by notice in writing to the Company and, if given by the Holders, to the Trustee, specifying the respective Events of Default, and the same shall become immediately due and payable.

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal, premium, if any, or interest) if and so long as a committee of its Trust Officers in good faith determines that withholding notice is in the interest of the Holders.

I-8

Notwithstanding clause (c) of the definition of “Event of Default” in the Indenture or any other provision of the Indenture, except as provided in the final sentence of this paragraph, the sole remedy for any failure to comply by the Company with Section 5.4 of the Indenture shall be the payment of liquidated damages as described in the following sentence, such failure to comply shall not constitute an Event of Default, and holders of the Notes shall not have any right under the Indenture or the Notes to accelerate the maturity of the Notes as a result of any such failure to comply. If a failure to comply by the Company with Section 5.4 of the Indenture continues for 60 days after the Company receives notice of such failure to comply in accordance with clause (c) of the definition of “Event of Default” in the Indenture (such notice, the “Reports Default Notice”), and is continuing on the 60th day following the Company’s receipt of the Reports Default Notice, the Company will pay liquidated damages to all holders of Notes at a rate per annum equal to 0.25% of the principal amount of the Notes from the 60th day following the Company’s receipt of the Reports Default Notice to but not including the earlier of (x) the 121st day following the Company’s receipt of the Reports Default Notice and (y) the date on which the failure to comply by the Company with Section 5.4 of the Indenture shall have been cured or waived. On the earlier of the date specified in the immediately preceding clauses (x) and (y), such liquidated damages will cease to accrue. If the failure to comply by the Company with Section 5.4 of the Indenture shall not have been cured or waived on or before the 121st day following the Company’s receipt of the Reports Default Notice, then the failure to comply by the Company with Section 5.4 of the Indenture shall on such 121st day constitute an Event of Default. A failure to comply with Section 5.4 of the Indenture automatically shall cease to be continuing and shall be deemed cured at such time as the Company furnishes to the Trustee the applicable information or report (it being understood that the availability of such information or report on the Commission’s EDGAR service (or any successor thereto) shall be deemed to satisfy the Company’s obligation to furnish such information or report to the Trustee).

Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

No past, present or future director, officer, employee, stockholder or incorporator, as such, of the Company or any successor corporation shall have any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes.

THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

This Note endorsed hereon shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Note.

Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures the Company has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

The Company shall furnish to any Holder upon written request and without charge to the Holder a copy of the Indenture which has in it the text of this Note in larger type. Requests may be made to:

Dear Ladies and Gentlemen,

We have acted as New York counsel to MGM Resorts International, a Delaware corporation (the “Company”), in connection with the offer and sale of $850,000,000 aggregate principal amount of 6.125% Senior Notes due 2029 (the “Notes”) issued by the Company pursuant to the terms of the Underwriting Agreement dated September 3, 2024 (the “Underwriting Agreement”) by and among BofA Securities, Inc. as representative of the several underwriters named therein, the Company and the subsidiary guarantors named therein (the “Subsidiary Guarantors”). The Notes, when issued, will be guaranteed (the “Guarantees”) by the Subsidiary Guarantors. The Notes, together with the Guarantees, are referred to as the “Securities”.

In rendering the opinions expressed below, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such corporate records and agreements and other instruments, certificates of public officials, certificates of officers and representatives of the Company, the Subsidiary Guarantors and the Trustee and other documents as we have deemed necessary as a basis for the opinions hereinafter expressed, including (i) the registration statement on Form S-3, File No. 333-277326, filed on February 23, 2024 by the Company under the Securities Act of 1933, as amended (the “Securities Act”), with the Securities and Exchange Commission (the “Registration Statement”); (ii) the prospectus dated February 23, 2024 (the “Base Prospectus”); (iii) the preliminary prospectus supplement dated September 3, 2024 relating to the Securities; (iv) the prospectus supplement dated September 3, 2024; (v) the indenture, dated as of April 9, 2024, among the Company, the Subsidiary Guarantors named therein and U.S. Bank Trust Company, National Association, as Trustee (the “Trustee”), as supplemented by a second supplemental indenture, dated as of September 17, 2024 (together, the “Indenture”); and (vi) the Underwriting Agreement.

In such examination, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, conformed or photostatic copies and the authenticity of the originals of such latter documents. As to all questions of fact material to this opinion that have not been independently established, we have relied upon certificates or comparable documents of officers and representatives of the Company.

In connection with this opinion, we have also assumed that (i) except with respect to CityCenter Holdings, LLC, MGM Dev, LLC, MGM Detroit Holdings, LLC, MGM Lessee, LLC, MGM Lessee II, LLC, MGM Lessee III, LLC, Nevada Property 1 LLC, Nevada Restaurant Venture 1 LLC, Nevada Retail Venture 1 LLC, MGM Yonkers, Inc., MMNY Land Company, Inc. and NP1 Pegasus LLC, each of the Subsidiary Guarantors has been duly organized and is validly existing and in good standing in the jurisdiction in which it was formed, (ii) each of the Subsidiary Guarantors has the full power and authority to execute and deliver the Indenture and the Guarantees and to perform its obligations thereunder, and (iii) all action required to be taken by each of the Subsidiary Guarantors for the due and proper authorization, execution and delivery of the Indenture and the Guarantees and the consummation of the transactions contemplated thereby has been duly and validly taken.

Based upon and subject to the foregoing, and subject to the assumptions and qualifications set forth herein, and having regard to legal considerations we deem relevant, we are of the opinion that (assuming the due authentication by the Trustee):

(1) The Notes constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

(2) The Guarantees issued under the Indenture constitute valid and binding obligations of the Subsidiary Guarantors, enforceable against the Subsidiary Guarantors in accordance with their terms.

The opinions expressed above with respect to validity, binding effect and enforceability are subject to the effect of any applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution thereunder may be limited by federal or state securities laws or public policy relating thereto.

The foregoing opinions are limited to matters involving the law of the State of New York, the Delaware General Corporation Law and the federal law of the United States.

We hereby consent to the reference to us under the heading “Legal Matters” in the Base Prospectus constituting a part of the Registration Statement and in any related prospectus supplement and to the filing of this opinion as Exhibit 5.1 of the Registration Statement. By giving this consent, we do not 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 promulgated thereunder.

Exhibit 5.2

September 17, 2024

MGM Resorts International

3600 Las Vegas Boulevard South

Las Vegas, Nevada 89109

Ladies and Gentlemen:

We have acted as special Massachusetts counsel to MGM Resorts International, a Delaware corporation (the “Company”), and MGM MA SUB, LLC, a Subsidiary Guarantor under the Underwriting Agreement identified below and referred to herein as the “Massachusetts Guarantor,” with respect to matters of Massachusetts law arising in connection with the issuance by the Company of $850,000,000 aggregate principal amount of the Company’s 6.125% Senior Notes due 2029 (the “Notes”), pursuant to the Underwriting Agreement (the “Underwriting Agreement”), dated as of September 3, 2024, between the Company and BofA Securities, Inc., as representative of the several Underwriters named therein. The Notes are issued pursuant to an Indenture, dated as of April 9, 2024 (the “Base Indenture”) between the Company and U.S. Bank Trust Company, National Association, as Trustee (the “Trustee”), as supplemented by the Second Supplemental Indenture, dated as of September 17, 2024 (the “Supplemental Indenture”) among the Company, the Subsidiary Guarantors, and the Trustee, and the Notes are guaranteed as to payment of principal, premium, if any, and interest by the subsidiaries of the Company identified on the signature pages to the Supplemental Indenture (with respect to each subsidiary, a “Guarantee” and collectively, the “Guarantees”). The initial issuance and sale of the Notes by the Company and the granting of the Guarantees by the Subsidiary Guarantors is referred to herein as the “Transaction.”

This opinion letter, including the schedules hereto (the “Opinion Letter”), is being rendered at the request of the Company. All capitalized terms not otherwise defined herein shall have the same meaning as they are given in the Underwriting Agreement.

In connection with this Opinion Letter, we have examined the following documents (the “Transaction Documents”), each dated as of the date hereof unless otherwise specified:

MGM Resorts International

Page | 2

In addition to the Transaction Documents, we have also examined each of the other documents listed on Schedule A attached hereto, including the therein defined “Governing Document” (together with the Transaction Documents, the “Documents”).

We have, without independent investigation, relied upon the representations and warranties of the various parties as to matters of objective fact contained in the Documents. Except for the Documents, we have not examined the records of the Company or the Massachusetts Guarantor, nor of any court or any public, quasi-public, private or other office in any jurisdiction, and our opinions are subject to the matters that an examination of such records would reveal.

We have assumed that the Company and the Subsidiary Guarantors other than the Massachusetts Guarantor are duly incorporated, validly existing and in good standing under the laws of their respective jurisdictions of incorporation or organization, have all requisite corporate or other organizational power and authority to enter into, deliver, and perform their obligations under the Transaction Documents to which they are a party, and have taken all necessary corporate action to authorize the execution, delivery and performance by such entities of the Transaction Documents to which they are a party. We have assumed that the Transaction Documents constitute the valid, binding and enforceable obligations of all parties thereto other than the Massachusetts Guarantor. We have also assumed: (i) each natural person executing any of the Documents has sufficient legal capacity to enter into such Documents; (ii) there are no agreements or understandings among the parties to or bound by the Documents or involved in the Transaction, and there is no usage of trade or course of prior dealing among such parties, that would define, modify, waive, or qualify the terms of the Documents or any of the agreements relating to the Transaction. In the course of our representation of the Massachusetts Guarantor in connection with the Transaction, nothing has come to our attention which causes us to believe reliance upon any of those assumptions is inappropriate, and, with your concurrence, the opinions hereafter expressed are based upon those assumptions.

With your approval, our opinions hereafter expressed are limited to Chapters 156C and 156D of the Massachusetts General Laws (the “Applicable Massachusetts Law”) and the Federal law of the United States of America, except with respect to the opinions hereafter expressed in numbered paragraph 1, as to which we have relied solely on the certificate listed on Schedule A of the Secretary of the Commonwealth of The Commonwealth of Massachusetts. We express no opinion as to the laws of any other jurisdiction. We express no legal opinion upon any matter other than those explicitly addressed in numbered paragraphs 1 through 7 below, and our express opinions therein contained shall not be interpreted to be implied opinions upon any other matter. For example, without limiting the generality of the foregoing, unless expressly stated herein we are rendering no opinion upon the following legal issues, laws or provisions of the Documents: (a) securities laws of any jurisdiction; (b) state “Blue Sky” laws and regulations; (c) gaming laws of any jurisdiction; and (d) usury laws.

Based upon and subject to the foregoing, we are of the opinion that:

The opinions set forth herein are provided to you as legal opinions only and not as a guaranty or warranty of the matters discussed herein. The opinions expressed herein are as of the date hereof, and we expressly disclaim any responsibility to update any opinions after the date hereof.

We hereby consent to being named in the Registration Statement as having prepared this Opinion Letter and to the filing of this Opinion Letter as an exhibit to the Registration Statement. By giving this consent, we do not 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 promulgated thereunder.

The opinions set forth herein are expressly limited to the effect on the Transactions only of the internal laws of the State of Nevada, and we do not purport to be experts on, or to express any opinion with respect to the applicability thereto or to the effect thereon of the laws of any other jurisdiction or as to matters of local law or the laws, rules or regulations of local governmental departments or agencies within the State of Nevada. We express no opinion herein concerning, and we assume no responsibility as to laws or judicial decisions related to, or any orders, consents or other authorizations or approvals as may be required by, any federal laws, rules or regulations, including, without limitation, any federal securities laws, rules or regulations, any state securities or “Blue Sky” laws, rules or regulations, any federal or state banking, antitrust, bankruptcy or insolvency laws, rules or regulations, or the CARES Act or any other coronavirus-related legislation or federal or state laws, rules, regulations, orders or directives related thereto.

Based upon the foregoing, and subject to the qualifications, limitations, exceptions and assumptions set forth herein, we are of the opinion that:

1. Each of the Nevada Guarantors is validly existing as a corporation or limited liability company, as applicable, and is in good standing under the laws of the State of Nevada.

2. Each of the Nevada Guarantors has the corporate, limited liability company or general partnership, as applicable, power and authority to (a) execute and deliver each of the Notes Documents to which it is a party, perform its obligations thereunder and consummate the Transactions and (b) own, lease and operate its properties as described in the Registration Statement, the Preliminary Prospectus, and the Prospectus.

4. Each of the Nevada Guarantors has duly executed and delivered each of the Notes Documents to which it is a party.

5. The execution and delivery by each of the Opinion Parties of the Notes Documents to which it is a party, the performance by each of the Opinion Parties of its obligations thereunder and the consummation of the Transactions (including the issuance of the Notes and the Subsidiary Guarantees) do not violate the Governing Documents, any Applicable Nevada Law or any Applicable Nevada Order.

6. No Nevada Governmental Approval is required for the execution and delivery by any of the Opinion Parties of the Notes Documents to which it is a party or the consummation of the Transactions except (a) as set forth in the Registration Statement, the Preliminary Prospectus, and the Prospectus, (b) those that have been obtained or made on or prior to the date hereof and are in full force and effect, and (c) such filings with the Nevada Gaming Authorities as are referenced in qualification paragraph (A)(iii) below.

7. The statements made in the Registration Statement and the Prospectus under the captions “Risk Factors—Risks Relating to the Notes—We may require you to dispose of your notes or redeem your notes if any gaming authority finds you unsuitable to hold them”, “Risk Factors—Risks Related our Business—Our businesses are subject to extensive regulation and the cost of compliance or failure to comply with such regulations may adversely affect our business and results of operations”, “Regulation and Licensing” (including the statements incorporated by reference therein in Exhibit 99.1 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, under the heading “Licensing, Suitability and Qualification Determinations”), “Description of Notes—Mandatory Disposition Pursuant to Gaming Laws” and “Description of Notes—Compliance with Gaming Laws” have been reviewed by us and, insofar as such statements purport to constitute summaries of the Nevada Gaming Laws and matters arising thereunder, such statements constitute fair summaries thereof in all material respects.

The opinions expressed herein are subject to and limited by the following qualifications, assumptions and limitations:

(A) We have assumed that:

(i) neither the consummation of the Transactions nor the exercise of rights under the Notes Documents will result in any person acquiring “control” (as that term is defined under the Nevada Gaming Laws) of any Opinion Party that is licensed by or registered with the Nevada Gaming Authorities (collectively, the “Gaming Parties”) without first obtaining the approvals required by the Nevada Gaming Laws;

(ii) no party to the Notes Documents will exercise significant influence (as set forth in NRS 463.165) over the gaming activities or operations of the Gaming Parties without first securing the approvals required by the Nevada Gaming Laws; and

(iii) the Opinion Parties will file, on a timely basis, any applicable informational transaction reports with respect to the Transactions that may be required after the date hereof by NGC Regulation 8.130 and will provide all notices and make any filings that may be required after the date hereof by any order issued by the Nevada Gaming Authorities.

(B) We note that each of the Underwriters, the holders of the Notes, the Trustee and their respective successors and assignees are subject to being called forward by the Nevada Gaming Authorities, in their sole and absolute discretion, for a finding of suitability, and in this regard, we express no opinion as to whether the Nevada Gaming Authorities would call any such person forward for such a finding and, if they did, whether the Nevada Gaming Authorities would find any such person suitable.

(C) The opinions contained herein are subject to, and we express no opinion as to, the effect of bankruptcy, insolvency, reorganization, moratorium, anti-deficiency, and other similar laws, rules and regulations now or hereafter in effect relating to or affecting the enforcement of creditors’ rights generally, the federal Bankruptcy Code, the Uniform Fraudulent Transfer Act (as codified in NRS Chapter 112), and any other laws, rules or regulations relating to fraudulent or unlawful conveyances, distributions and transfers.

The opinions expressed herein are based upon the Applicable Nevada Law in effect and the facts in existence as of the date of this opinion letter. In delivering this opinion letter to you, we assume no obligation, and we advise you that we shall make no effort, to update the opinions set forth herein, or to conduct any inquiry into the continued accuracy of such opinions, or to apprise any addressee hereof, its counsel or its assignees of any facts, matters, transactions, events or occurrences taking place, and of which we may acquire knowledge, after the date of this opinion letter, or of any change in any Applicable Nevada Law or any facts occurring after the date of this opinion letter, which may affect the opinions set forth herein. No opinions are offered or implied as to any matter, and no inference may be drawn, beyond the strict scope of the specific issues expressly addressed by the opinions herein.

This opinion is intended solely for the use of the addressees in connection with the Notes Documents.

MGM Resorts International

Ladies and Gentlemen:

We have acted as special Mississippi counsel to MGM Resorts International, a Delaware corporation (the “Company” or “MGM Resorts”), in connection with that certain Underwriting Agreement dated September 3, 2024 among MGM Resorts, the Subsidiary Guarantors, and BofA Securities, Inc., as Representative of the several Underwriters named in Schedule A thereto (the “Underwriting Agreement”). This opinion is delivered pursuant to Section 5(b)(5) of the Underwriting Agreement. Capitalized terms used herein and not defined herein shall have the meanings given to them in the Underwriting Agreement and Exhibit E thereto.

In rendering this opinion, we have examined executed originals, counterparts or copies, certified or otherwise identified to our satisfaction as being true copies, of each of the documents referenced below:

BUTLER SNOW LLP

MGM Resorts International

September 17, 2024

Page 2

The documents listed above as A, B, C, D, E, F, G and H are collectively referred to herein as the “Transaction Documents.”

We have examined, and relied upon for purposes of this opinion, one or more certificates of officers and representatives of each of MGM Resorts and the Mississippi Subsidiary with respect to certain factual matters, which, with your permission, we have not independently verified. In addition, except as stated below, we have also examined, and relied upon for purposes of this opinion, originals or copies, certified or otherwise identified to our satisfaction, of (i) corporate records, agreements and other instruments and (ii) documents of public officials, and we have conducted such other investigations of fact or law as we have deemed necessary or advisable for purposes of this opinion.

Except as to the documents referenced above, we have not reviewed, and we express no opinion as to, any instrument or agreement referred to or incorporated by reference in the Transaction Documents. We have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of natural persons, the conformity to originals of all copies of all documents submitted to us, and the accuracy and totality of all such documents submitted to us as originals or copies. We have assumed that the most recent drafts of the Transaction Documents submitted to us do not vary in any material respect from their executed versions.

We have assumed that MGM Resorts and those of the Company Subsidiaries which are not the Mississippi Subsidiary (the “Other Subsidiaries”) are duly incorporated, validly existing and in good standing under the laws of their respective jurisdictions of incorporation or organization, have all requisite corporate or other organizational power and authority to enter into, deliver, and perform their obligations under the Transaction Documents to which they are a party, and have taken all necessary corporate action to authorize the execution, delivery and performance by such entities of the Transaction Documents to which they are a party. We have assumed that the Transaction Documents constitute the valid, binding and enforceable obligations of all parties thereto other than the Mississippi Subsidiary.

Based upon the foregoing, and subject to the foregoing and the further qualifications, assumptions, and limitations set forth below, we are of the opinion that, as of the date hereof:

(i) The Mississippi Subsidiary has been duly organized and, based solely on the Good Standing Certificate applicable to the Mississippi Subsidiary, is validly existing as a limited liability company in good standing under the laws of Mississippi. Assuming the capital contribution of the Company stated in the operating agreement was received by the Mississippi

MGM Resorts International

September 17, 2024

Page 3

Subsidiary, all of the issued and outstanding membership interests of the Mississippi Subsidiary have been validly issued and, based solely on our review of the operating agreement, are directly owned of record by the Company. Assuming the Company acquired such membership interests in good faith and without knowledge of any adverse claim, to our knowledge, except as disclosed in each of the Pricing Disclosure Package and the Prospectus, the Company holds such membership interests free and clear of any security interest, lien, encumbrance or other adverse claim. To our knowledge, except as disclosed in each of the Pricing Disclosure Package and the Prospectus, there is no outstanding subscription, option, warrant or other right calling for the issuance of any membership interests of the Mississippi Subsidiary or any security convertible into, exercisable for, or exchangeable for membership interests of the Mississippi Subsidiary.

(ii) The Mississippi Subsidiary has all requisite limited liability company power and authority to own, lease and license its assets and properties, to conduct its businesses as described in the Pricing Disclosure Package and the Prospectus, but only to the extent the same are currently conducted and operated, and to enter into and perform its obligations under the Underwriting Agreement, the Indenture and its Subsidiary Guarantee, to the extent that it is a party thereto.

(iii) The Mississippi Subsidiary has taken all necessary limited liability company action to authorize the execution and delivery of the Underwriting Agreement, the Indenture and its Subsidiary Guarantee, to the extent that it is a party thereto. The execution and delivery of the Underwriting Agreement, the Indenture and the Subsidiary Guarantees and performance of the Underwriting Agreement, the Indenture and the Subsidiary Guarantees by the respective parties thereto and the consummation of the transactions contemplated in the Underwriting Agreement, the Pricing Disclosure Package and the Prospectus and compliance by the Mississippi Subsidiary with their respective obligations thereunder will not, to our knowledge: (1) conflict with or constitute a breach of, or default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of any Mississippi Subsidiary pursuant to, any contract, indenture, mortgage, loan agreement, note, lease or other instrument to which any Mississippi Subsidiary is a party or by which it or any of them may be bound, or to which any of the property or assets of any Mississippi Subsidiary is subject which would result in a material adverse effect on the condition, financial or otherwise, or the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise; or (2) result in any violation of the provisions of (A) any applicable law, administrative regulation or administrative or court decree which would result in a material adverse effect on the condition, financial or otherwise, or the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise or (B) the certificate of formation or operating agreement of any Mississippi Subsidiary.

(iv) To our knowledge, the Mississippi Subsidiary is not in violation of any term or provision of its certificate of formation or operating agreement. Except as disclosed in each of the Pricing Disclosure Package and the Prospectus, to our knowledge, no default exists and no event has occurred which with notice or lapse of time, or both, would constitute a default in the due performance and observance of any express term, covenant or condition by such Mississippi Subsidiary of any indenture, mortgage, deed of trust, note or any other agreement or instrument to which such Mississippi Subsidiary is a party or by which it or any of its assets or properties or

businesses may be bound or affected, where the consequences of such default would have a material adverse effect on the assets, properties, business, results of operations, prospects or financial condition of the Company and its subsidiaries considered as one enterprise.

(v) No authorization, approval, consent, order, license, certificate or permit (each, a “Mississippi Permit”) required of or from any governmental or regulatory body (each, a “Mississippi Gaming Authority”) under the Mississippi Gaming Control Act and the rules and regulations promulgated thereunder (collectively, “Mississippi Gaming Laws”) is required for the performance by each Mississippi Subsidiary of the Underwriting Agreement or for the consummation of the transactions contemplated thereby or any other transaction described in each of the Pricing Disclosure Package and the Prospectus to be entered into in connection therewith (including the issuance of the Subsidiary Guarantees) except for such Mississippi Permits that have been obtained. The Underwriting Agreement, the Pricing Disclosure Package and the Prospectus have been presented to all Mississippi Gaming Authorities to the extent required by any Mississippi Gaming Laws, and such documents and the transactions contemplated hereby or thereby have been approved by or on behalf of such Mississippi Gaming Authorities to the extent required by any Mississippi Gaming Laws, or the requirement for approval has been waived, and such approvals or waivers have not been revoked, modified or rescinded.

(vi) The statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 included in Exhibit 99.1 under the heading “Description of Regulation and Licensing,” insofar as such statements purport to constitute summaries of the Mississippi Gaming Laws and matters arising thereunder and in each case as in effect at the date such statements were made, were true and correct in all material respects as of the Applicable Time and as of the Closing Time.

(vii) The Underwriting Agreement, the Indenture and the Subsidiary Guarantees have been duly and validly authorized, executed and delivered by the Mississippi Subsidiary party thereto.

(viii) To our knowledge, there are no material legal or governmental proceedings pending or threatened other than any regularly scheduled re-licensing proceedings now pending before any Mississippi Gaming Authority and other than those disclosed in the Pricing Disclosure Package and the Prospectus, the adverse determination of which would have a material adverse effect on the condition, financial or otherwise, or the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise.

(ix) The Mississippi Subsidiary is not, nor will it be upon the execution and delivery of the Transaction Documents, subject to regulation under any Mississippi statute or regulation limiting their ability to incur indebtedness for borrowed money, except the Mississippi Gaming Laws and any rules, ordinances or regulations of local regulatory authorities, the provisions of which have been complied with by the Mississippi Subsidiary.

In rendering the opinions expressed herein, we have assumed, without inquiry or investigation, that there has been no mutual mistake of fact or misunderstanding, fraud, duress, or undue influence involved with respect to any party, and that each party has complied with any requirement of good faith, fair dealing and conscionability.

Ladies and Gentlemen:

As special New Jersey counsel for MGM Resorts International, a Delaware corporation (the “Company”); AC Holding Corp. II, a Nevada corporation (the “Nevada Subsidiary”); and Marina District Development Company, LLC, a New Jersey limited liability company (“MDDC”), Marina District Development Holding Co., LLC, a New Jersey limited liability company (“MDDHC”) and MAC, CORP., a New Jersey corporation (“MAC”, and together with MDDC and MDDHC, individually, a “New Jersey Subsidiary” and collectively, the “New Jersey Subsidiaries”), we have been requested by our clients to render an opinion pursuant to Section 5(b)(3) of the Underwriting Agreement dated as of September 3, 2024 (the “Underwriting Agreement”) between the Company, BofA Securities, Inc. (“BofA”) and each of the other Underwriters named in Schedule A thereto (collectively, the “Underwriters”) for whom BofA is acting as representative with respect to the issuance and sale by the Company of $850,000,000 aggregate principal amount of the Company’s 6.125% Senior Notes due 2029 (the “Notes”). All capitalized terms not defined herein shall have the same definitions as those ascribed to them in the Underwriting Agreement.

In rendering the opinions set forth herein, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents (the “Transaction Documents”), each dated as of the date hereof unless otherwise specified:

Except as to the documents identified above, we have not reviewed, and express no opinion as to, any instrument or agreement referred to or incorporated by reference in the Transaction Documents.

We have also examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents (the “Company Documents”), each dated as of the date hereof unless otherwise specified:

Page 3

We call to your attention that we have not examined any court, real estate or commercial financing records. We have also made such examination of law as we have deemed necessary for purposes of this opinion.

In our examination, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to the original documents of all documents submitted to us as certified or photocopies, the authenticity of the originals of such latter documents, the accuracy and completeness of all documents and records reviewed by us, the accuracy, completeness and authenticity of each certificate issued by any government official, office or agency and the absence of change in the information contained therein from the effective date of any such certificate.

We have assumed that each of the parties to the Transaction Documents other than the New Jersey Subsidiaries (the “Other Parties”) has satisfied all applicable legal requirements necessary to make the Transaction Documents enforceable against it and has complied with all legal requirements pertaining to its status as such status relates to its rights to enforce the Transaction Documents against the New Jersey Subsidiaries, or any of them. We have also assumed that the conduct of the parties to the Transaction Documents complies with any requirements of good faith, fair dealing and absence of unconscionability, and there has not been any mutual mistake of fact, fraud, duress or undue influence.

Without limiting the effect of the preceding paragraph, we have also assumed that (i) each of the Company, the Nevada Subsidiary and Mirage Resorts, LLC, a Nevada limited liability company (“MRL”), has all requisite corporate power and authority to enter into, deliver and perform its obligations under the Transaction Documents to which it is a party; (ii) each of the Company, the Nevada Subsidiary and MRL has taken all necessary corporate action to authorize the execution, delivery and performance by it of the Transaction Documents to which it is a party; (iii) each of the Company, the Nevada Subsidiary and MRL has validly executed and delivered the Transaction Documents to which it is a party; and (iv) the Company’s obligations and those of the Nevada Subsidiary, MRL and the New Jersey Subsidiaries pursuant to the Transaction Documents, to the extent that any of them is a party thereto, are the legal, valid and binding obligations of the Company, the Nevada Subsidiary, MRL and the New Jersey Subsidiaries, respectively, enforceable in accordance with the terms of such documents.

As to any facts material to our opinions expressed herein, we have relied upon the representations and warranties of the Company, the Nevada Subsidiary, MRL and the New Jersey Subsidiaries contained in the Transaction Documents and upon a certificate of the Assistant Secretary of the Company, the Nevada Subsidiary, MRL and the New Jersey Subsidiaries, with respect to certain factual matters (collectively, the “Officer’s Certificate”). In this regard, we have assumed the due authorization, execution and delivery of the Transaction Documents by all of the Other Parties thereto, that all of the Other Parties thereto have full power and legal right to enter into the Transaction Documents and to consummate the transactions contemplated thereby, and that each of the Transaction Documents constitutes a legal, valid and binding obligation of each of the Other Parties thereto.

To the extent that a statement herein is qualified by the phrases “to our knowledge” or “known to us”, or by similar phrases, it is intended to indicate that, during the course of our representation of the Company, the Nevada Subsidiary, MRL and the New Jersey Subsidiaries in connection with the Transaction Documents, and based upon an inquiry of the attorneys presently in this firm who have rendered substantive legal services in connection with the representation of the Company, the Nevada Subsidiary, MRL and the New Jersey Subsidiaries with respect to the Transaction Documents, no information that would give us current actual knowledge of the inaccuracy of such statement has come to the attention of those attorneys presently in this firm who have rendered substantive legal services in connection with the representation of any of the Company, the Nevada Subsidiary, MRL and the New Jersey Subsidiaries with respect to the Transaction Documents. Except as expressly set forth above, such phrase does not mean that we have undertaken any independent investigation or review to determine the accuracy of any such statement. No inference as to our knowledge of any matters bearing on the accuracy of any such statement should be drawn from the fact of our representation of the Company, the Nevada Subsidiary, MRL and the New Jersey Subsidiaries.

Our opinion is limited in all respects to the laws of the United States and the State of New Jersey.

Based upon and subject to the foregoing and the qualifications hereinafter set forth, we are of the opinion that:

1. MAC has been duly incorporated and, based solely upon the MAC Good Standing Certificate, is validly existing as a corporation in good standing under the laws of New Jersey. All of the issued and outstanding shares of capital stock of MAC have been duly authorized and validly issued, and, to our knowledge and based on the Officer’s Certificate, are fully paid and nonassessable and are directly owned of record by MRL. Assuming MRL acquired such shares of MAC without knowledge of any security interest, lien, encumbrance or other adverse claim, then to the best of our knowledge, MRL holds such shares free and clear of any security interest, lien, encumbrance or other adverse claim. To our knowledge, except as disclosed in each of the Pricing Disclosure Package and the Prospectus, there is no outstanding subscription, option, warrant or other right calling for the issuance of any share of stock of MAC or any security convertible into, exercisable for, or exchangeable for stock of MAC.

Assuming MAC and the Company each acquired their respective limited liability company membership interests of MDDHC without knowledge of any security interest, lien, encumbrance or other adverse claim, then to the best of our knowledge, MAC and the Company each hold their respective limited liability company membership interests free and clear of any security interest, lien, encumbrance or other adverse claim. To our knowledge, except as disclosed in each of the Pricing Disclosure Package and the Prospectus, there is no outstanding subscription, option, warrant or other right calling for the issuance of any limited liability company membership interests of MDDHC or any security convertible into, exercisable for, or exchangeable for limited liability company membership interests of MDDHC.

Assuming MDDHC acquired such limited liability company membership interests of MDDC without knowledge of any security interest, lien, encumbrance or other adverse claim, then to the best of our knowledge, MDDHC holds such limited liability company membership interests free and clear of any security interest, lien, encumbrance or other adverse claim. To our knowledge, except as disclosed in each of the Pricing Disclosure Package and the Prospectus, there is no outstanding subscription, option, warrant or other right calling for the issuance of any limited liability company membership interests of MDDC or any security convertible into, exercisable for, or exchangeable for limited liability company membership interests of MDDC.
