The Merger Agreement and the transactions contemplated thereby were unanimously approved by the Executive Committee of the Issuer (the “Executive Committee”) upon the unanimous recommendation of a special committee of the board of directors of the Issuer (the “Special Committee” and, such recommendation, the “Special Committee Recommendation”)—a committee comprised solely of independent and disinterested directors that was established by the Executive Committee to review, evaluate and negotiate the Merger Agreement, make a determination as to whether the Transactions (as defined below) are fair to, and in the best interests of, the Issuer, its stockholders, and the equityholders of Manager and OpCo and make a recommendation to the Executive Committee with respect to the Transactions.

If the Mergers are consummated, the Class A Common Stock will be delisted from the New York Stock Exchange and deregistered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Delivery of Stockholder Written Consent

On April 2, 2024, (a) the HoldCos and (b) Ariel Emanuel and Patrick Whitesell and each of their respective personal revocable trusts that holds shares of Common Stock and/or OpCo Membership Interests, and the Executive Holdcos (together, the “Management Holders” and, together with the HoldCos, the “Specified Stockholders”), which collectively hold a majority of the combined voting power of the outstanding shares of Class A Common Stock, Class X Common Stock and Class Y Common Stock at that time, executed and delivered to the Issuer a written consent (the “Written Consent”) adopting and approving the Merger Agreement and the Transactions, including the Mergers. No further approval of the stockholders of the Issuer is required to adopt and approve the Merger Agreement.

Treatment of Equity Awards

As a result of the Company Merger, each outstanding restricted stock unit subject to service-based vesting conditions (each, a “Company RSU”) or performance-based vesting conditions (each, a “Company PSU”), pursuant to which the holder has a right to receive Company Class A Common Stock (or cash in an amount determined by reference to the

7

value thereof) following the vesting or lapse of restrictions applicable to such restricted stock unit, that is vested, but not yet settled as of the Effective Time will automatically be cancelled and converted into the right to receive an amount in cash equal to the product of (x) the Company Merger Consideration and (y) the number of shares of Class A Common Stock subject to such Company RSU or Company PSU, subject to certain tax deductions or withholdings as a result of the Transactions (the “RSU/PSU Consideration”), payable as soon as practicable following the the Effective Time. Each Company PSU that is unvested as of the Effective Time will, at the Effective Time, automatically be cancelled without any cash payment being made in respect thereof.

The treatment of each Company RSU that is not vested as of the Effective Time will be determined by the Executive Committee prior to the Effective Time, or, if not determined prior to the Effective Time in any event within forty (40) Business Days following the Effective Time, by the administrator of the Issuer stock plan as soon as reasonably practicable following the Effective Time.

In addition, at the Effective Time, each outstanding option to acquire Class A Common Stock (each, a “Company Option”) that is vested will automatically be cancelled and converted into the right to receive an amount in cash, without interest and subject to certain tax deductions or withholdings as a result of the Transactions, as soon as reasonably practicable after the Effective Time equal to the product of (a) the number of shares of Class A Common Stock subject to such Company Option, multiplied by (b) the Company Merger Consideration less the exercise price per share of such Company Option, in effect immediately prior to the Effective Time. Any Company Option that is not vested at the Effective Time or that has an exercise price per share equal to or greater than the Company Merger Consideration will be cancelled without any cash payment being made in respect thereof.

Termination and Fees

Either the Issuer, acting with the prior approval of the Special Committee, or the Parent Entities, may terminate the Merger Agreement in certain circumstances, including if (i) the Mergers are not completed by April 2, 2025 (the “Outside Date”), subject to certain limitations and as such date may be extended pursuant to the terms of the Merger Agreement or by the mutual written consent of the Company (acting with the prior approval of the Special Committee) and the Parent Entities, (ii) a governmental authority of competent jurisdiction, except a gaming authority, has enacted, issued, promulgated, enforced or entered any law permanently prohibiting the Mergers, and (iii) the other party breaches its representations, warranties or covenants in the Merger Agreement, subject in certain cases to the right of the breaching party to cure the breach. In addition, the Issuer, acting with the prior approval of the Special Committee, may terminate the Merger Agreement if the Parent Entities fail to consummate the closing after the Issuer has delivered written notice that all conditions to closing have been satisfied and the Issuer is prepared to consummate the closing. The Parent Entities and the Issuer (acting with the prior approval of the Special Committee) may also terminate the Merger Agreement by mutual written consent.

If the Merger Agreement is terminated in certain circumstances, including in connection with the Issuer’s entry into a Superior Proposal, OpCo would be required to pay the Parent Entities a termination fee of $288,500,000. If the Merger Agreement is terminated in certain circumstances, including a breach of Parent Entities’ obligations under the Merger Agreement, failure of the Specified Stockholders to provide the Written Consent, or Parent Entities’ failure to consummate the closing when required by the Merger Agreement, the Parent Entities would be required to pay OpCo a termination fee of $705,000,000 (the “Parent Termination Fee”).

Other Terms of the Merger Agreement

Each of the Company Entities, the Parent Entities and the Merger Subs has made customary representations, warranties and covenants in the Merger Agreement, including, among others, with respect to the Company Entities, covenant (i) to conduct their business in the ordinary course during the period between the date of the Merger Agreement and the consummation of the Transactions and (ii) not to engage in specified types of transactions or take specified actions during this period unless agreed to in writing by the Parent Entities. The parties have also agreed to use reasonable best efforts to consummate the Transactions as promptly as reasonably practicable, including taking all actions necessary to obtain the regulatory approvals necessary to complete the Transactions, subject to certain limitations.

The representations, warranties and covenants contained in the Merger Agreement have been made solely for the purposes of the Merger Agreement and as of specific dates; were made solely for the benefit of the parties to the Merger Agreement; are not intended as statements of fact, but rather as a way of allocating the risk between the parties in the event the statements therein prove to be inaccurate; have been modified or qualified by certain confidential disclosures that were made between the parties in connection with the negotiation of the Merger Agreement, which disclosures are not reflected in the Merger Agreement itself; may no longer be true as of a given date; and may apply standards of materiality in a way that is different from what may be viewed as material by Issuer stockholders or other security holders.

Voting and Support Agreement

Concurrently with the execution of the Merger Agreement, the HoldCos entered into a voting and support agreement (the “Voting and Support Agreement”) with the Issuer, Manager and OpCo, pursuant to which each of the HoldCos agreed that, until the earlier of the effective time of the Merger and the termination of the Merger Agreement, it will vote all of its shares of Common Stock (i) to the extent the Written Consent has been revoked, superseded or modified, in favor of the adoption of the Merger Agreement and the transactions contemplated thereby, (ii) in favor of any other matter necessary for the transactions contemplated by the Merger Agreement to be timely consummated, (iii) in favor of any other matter in which the approval of stockholders is unanimously requested by the Executive Committee in connection with the stockholders’ approval of the Merger Agreement and the transactions contemplated thereby, (iv) against any action, agreement or proposal which could reasonably be expected to impede, interfere with, delay or adversely affect the Mergers or the other transactions contemplated by the Merger Agreement, and (v) against any action, proposal, transaction or agreement that could reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Company Entities, Parent Entities and Merger Sub under the Merger Agreement, or of such HoldCo under the Voting and Support Agreement.

The holders of Class A Common Stock, Class X Common Stock and Class Y Common Stock will vote together as a single class on all matters submitted to stockholders for their vote or approval, except as required by applicable law.

By virtue of the Stockholder Agreement and the obligations and rights thereunder and certain other arrangements with such persons, the Reporting Persons acknowledge and agree that they are acting as a “group” with the Executive Parties within the meaning of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The Reporting Persons expressly disclaim beneficial ownership over any shares of Class A Common Stock that they may be deemed to beneficially own solely by reason of the Stockholder Agreement. Certain entities affiliated with the Executive Parties have separately made a Schedule 13D filing reporting their beneficial ownership of shares of Class A Common Stock.

As a result of the execution and delivery of the Preferred Equity Commitment Letter by Thirty Fifth Investment Company L.L.C., an affiliate of Mubadala Investment Company PJSC (“Mubadala”), the HoldCos may be deemed to have formed a “group” within the meaning of Section 13(d) of the Exchange Act with Mubadala in connection with Thirty Fifth Investment Company L.L.C.’s commitment to contribute amounts to the Parent Entities or the Merger Subs pursuant to the Preferred Equity Commitment Letter. The Reporting Persons have been notified that Mubadala is intending to separately file a Schedule 13D reporting its beneficial ownership of shares of Class A Common Stock. The beneficial ownership of the Reporting Persons does not include any shares of Class A Common Stock which may be beneficially owned by Mubadala and each of the Reporting Persons disclaims beneficial ownership over any such shares.

As a result of the execution and delivery of a Rollover Agreement by Mark Shapiro, HoldCos may be deemed to have formed a “group” within the meaning of Section 13(d) of the Exchange Act with Mark Shapiro in connection with his Rollover Interests pursuant to such Rollover Agreement. Based on information provided by Mark Shapiro to the Reporting Persons, as of the date hereof, Mark Shapiro beneficially owns 2,499,120 shares of Class A Common Stock, representing approximately 0.8% of the outstanding shares of Class A Common Stock.

(c) None of the Reporting Persons has effected any transaction in Class A Common Stock in the past 60 days.
