February 13, 2020

To Brokers, Dealers, Banks, Trust Companies and Other Nominees:

MGM Resorts International, a Delaware corporation (the “Company”), has appointed us to act as Dealer Managers in connection with its offer to purchase for cash up to $1,250,000,000 in aggregate purchase price of its issued and outstanding shares of common stock, par value $0.01 per share (each, a “Share,” and collectively, the “Shares”), at a price calculated as described herein and in the Offer to Purchase that is a price not greater than $34.00 nor less than $29.00 per Share to the seller in cash, less any applicable withholding taxes and without interest, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated February 13, 2020 (together with any amendments or supplements thereto, the “Offer to Purchase”), the related Letter of Transmittal (together with any amendments or supplements thereto, the “Letter of Transmittal”) and other related materials as may be amended or supplemented from time to time (collectively, with the Offer to Purchase and the Letter to Transmittal, the “Offer”).

The Company will, upon the terms and subject to the conditions of the Offer, determine a single per Share price that it will pay for Shares properly tendered and not properly withdrawn from the Offer, taking into account the total number of Shares properly tendered and the prices specified, or deemed specified, by tendering shareholders. We will select this single per Share price (the “Final Purchase Price”) as the lowest single purchase price (in increments of $0.25), not greater than $34.00 nor less than $29.00 per Share, that would allow the Company to purchase the maximum number of Shares for an aggregate purchase price not exceeding $1,250,000,000, or all Shares properly tendered and not properly withdrawn in the event that less than $1,250,000,000 in aggregate purchase price of Shares is properly tendered and not properly withdrawn. All Shares purchased in the Offer will be purchased at the Final Purchase Price, including Shares tendered at a price lower than the Final Purchase Price, subject to “Odd Lot” priority and the conditional tender provisions described in the Offer to Purchase.

Capitalized terms used herein and not defined herein shall have the meanings given to them in the Offer to Purchase. The description of the Offer in this letter is only a summary and is qualified by the terms and conditions of the Offer set forth in the Offer to Purchase, the Letter of Transmittal and other related materials.

The Company will not purchase any Shares tendered at prices in excess of the Final Purchase Price. The term “Expiration Date” refers to the specific time and date on which the Offer expires. Upon the terms and subject to the conditions of the Offer, if $1,250,000,000 in aggregate purchase price of Shares or less is properly tendered and not properly withdrawn, the Company will purchase all Shares properly tendered at or below the Final Purchase Price and not properly withdrawn prior to the Expiration Date. Only Shares properly tendered at prices at or below the Final Purchase Price, and not properly withdrawn, will be purchased in the Offer upon the terms of and subject to the conditions of the Offer (including the “Odd Lot” priority, proration and conditional tender provisions described in the Offer to Purchase). Under no circumstances will interest be paid on the Final Purchase Price for the Shares regardless of any delay in making such payment. All Shares acquired in the Offer, if any, will be acquired at the Final Purchase Price, including those Shares tendered at a price lower than the

Final Purchase Price. The Company reserves the right, in its sole discretion, to change the per Share purchase price range and to increase or decrease the number of Shares sought in the Offer, subject to applicable law and the authority of the Company to conduct a share repurchase program of up to $3 billion in aggregate purchase price of its outstanding Shares (the “Board Authorization”). In accordance with the rules of the Securities and Exchange Commission, if more than $1,250,000,000 in aggregate purchase price of Shares is tendered in the Offer at or below the Final Purchase Price, subject to the Board Authorization, the Company may increase the number of Shares accepted for payment in the Offer by no more than 2% of the outstanding Shares without extending the Expiration Date.

The Company expressly reserves the right, in its sole discretion, to (i) upon the occurrence of any of certain conditions to the Offer more specifically described in the Offer to Purchase, (a) terminate the Offer and return all tendered Shares to the tendering shareholders, (b) extend the Offer and, subject to the withdrawal rights set forth in the Offer to Purchase, retain all of the tendered Shares until the expiration of the Offer as so extended, (c) waive a condition to the Offer and, subject to any requirement to extend the period of time during which the Offer is open, purchase all of the Shares properly tendered and not properly withdrawn prior to the Expiration Date or (d) delay acceptance of, or payment for, Shares, subject to applicable law, until satisfaction or waiver of such condition, or (ii) amend the Offer in any respect, subject to applicable law.

If the conditions to the Offer have been satisfied or waived and more than $1,250,000,000 in aggregate purchase price of Shares has been properly tendered and not properly withdrawn prior to the Expiration Date, the Company will purchase Shares on the following basis:

(i) first, the Company will purchase all Odd Lots of less fewer 100 Shares at the Final Purchase Price from shareholders who properly tender all of their Shares at or below the Final Purchase Price and who do not properly withdraw them before the Expiration Date. Tenders of less than all of the Shares owned, beneficially or of record, by such Odd Lot Holder will not qualify for this preference;

(ii) second, after purchasing all Odd Lots that were properly tendered at or below the Final Purchase Price, subject to the conditional tender provisions described in the Offer to Purchase (whereby a holder may specify the minimum number of such holder’s Shares that must be purchased if any such Shares are purchased), the Company will purchase all Shares properly tendered at or below the Final Purchase Price on a pro rata basis with appropriate adjustment to avoid purchases of fractional Shares; and

(iii) third, only if necessary to permit the Company to purchase $1,250,000,000 in aggregate purchase price of Shares (or such greater amount the Company may elect to purchase, subject to applicable law and the Board Authorization), the Company will purchase Shares conditionally tendered (for which the condition was not initially satisfied) at or below the Final Purchase Price, by random lot, to the extent feasible. To be eligible for purchase by random lot, shareholders whose Shares are conditionally tendered must have tendered all of their Shares at or below the Final Purchase Price. Random lot will be facilitated by the Company.

As a result of the foregoing priorities applicable to the purchase of Shares properly tendered, it is possible that fewer than all Shares tendered by a shareholder will be purchased or that, if a tender is conditioned upon the purchase of a specified number of Shares, none of those Shares will be purchased even though those Shares were properly tendered at prices at or below the Final Purchase Price and not properly withdrawn. Shares not purchased in the Offer, including Shares tendered at prices in excess of the Final Purchase Price and Shares not purchased because of proration or conditional tender, will be returned to the tendering shareholders at the Company’s expense promptly after the Expiration Date. See Section 1, Section 3 and Section 5 of the Offer to Purchase.

The Offer is subject to certain conditions. See Section 7 of the Offer to Purchase.
