Ladies and Gentlemen:

MGM Resorts International, a Delaware corporation (the “Company”), confirms its agreement with BofA Securities, Inc. (“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., ▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: High Yield Legal Department with a copy at the same address to: ▇▇▇▇_▇▇_▇▇▇▇▇_▇▇▇▇▇▇▇@▇▇▇▇.▇▇▇, and with a copy to ▇▇▇▇▇▇ ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, ▇▇ ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, attention of ▇▇▇▇▇ ▇. ▇▇▇▇▇, and notices to the Company shall be directed to it at ▇▇▇▇ ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇, attention of ▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Executive Vice President, General Counsel and Secretary, with a copy to Milbank LLP, ▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, attention of ▇▇▇ ▇▇▇▇▇▇.

SECTION 11. Parties. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the 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.

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.

(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.
