This statement on Schedule 13D relates to the Reporting Persons’ (as defined in Item 2 below) beneficial ownership interest in the Class A Common Stock, par value $0.0001 per share (the “Common Stock”), of Landcadia Holdings, Inc., a Delaware corporation (the “Corporation” or the “Issuer”). The address of the principal executive office of the Corporation is 1510 West Loop South Houston, TX 77027.

This statement relates to shares of Common Stock held directly by Master Fund. The general partner of Master Fund is SHGP, and SHCM acts as the investment manager to Master Fund. AIC is the sole member of both SHGP and SHCM. Investors invest in one or more of the following feeder funds: Sunley House Capital Fund LP, Sunley House Capital Limited Partnership, Sunley House Capital Fund Ltd. and Sunley House Capital Ltd. (collectively, the “Sunley House Feeder Funds”), which are the limited partners of Master Fund. None of the Sunley House Feeder Funds owns shares of Common Stock directly and none has investment authority over the shares of Common Stock held directly by Master Fund. Information regarding the identity of the executive officers and directors of AIC is set forth on Schedule A attached to this Schedule 13D.

(b) The principal business address of each Reporting Person is 800 Boylston Street, Suite 3300, Boston, MA 02199-8069.

(c) The principal business of AIC is to operate as an investment advisory firm and to make private equity investments. The principal business of SHCM is to operate as an investment advisory firm and to make investments in publicly-traded securities. The principal business of the Master Fund is to provide risk capital for, and make investments in the securities of, publicly-traded companies and other businesses. SHGP serves as the general partner of the Master Fund.

(d) & (e) During the last five years, none of the Reporting Persons nor any person listed on Schedule A has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). During the last five years, none of the Reporting Persons nor any person listed on Schedule A has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which any such person was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, Federal or State securities laws or finding any violations with respect to such laws.

Master Fund used approximately $20,330,000 (including brokerage commissions) of its working capital in the aggregate to purchase the shares of Common Stock reported in this Schedule 13D. Such shares of Common Stock are or may be held from time to time by Master Fund in margin accounts established with

its brokers or banks and a portion of the purchase price for the Common Stock may be obtained through margin borrowing. Securities positions which may be held in the margin accounts, including the Common Stock, may be pledged as collateral security for the repayment of debit balances in the margin accounts.

Master Fund acquired the shares of Common Stock for investment in the ordinary course of business, as it believed that such shares represented an attractive investment opportunity. In addition, the Reporting Persons intend to engage in discussions with the Issuer concerning a potential investment in or other financing involving the Issuer.

In connection with the Master Fund’s investment in the Issuer, and as may be appropriate from time to time, each of the Reporting Persons may also consider the feasibility and advisability of various alternative courses of action with respect to such investment, including, without limitation: (a) the acquisition or disposition by the Reporting Persons of its shares of Common Stock, including through derivative transactions which may include security-based swaps and short sales; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) changes in the present board of directors or management of the Issuer; (e) a material change in the present capitalization or dividend policy of the Issuer; (f) other material changes in the Issuer’s business or corporate structure; (g) changes in the Issuer’s certificate of incorporation or bylaws or other actions that may impede the acquisition of control of the Issuer by any person; (h) causing any class of the Issuer’s securities to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) causing a class of equity securities of the Issuer to become eligible for termination of registration pursuant to Section 12 of the Exchange Act; or (j) any action similar to those enumerated above. The Reporting Persons may communicate with the Board, members of management and/or other stockholders from time to time with respect to operational, strategic, financial or governance matters or otherwise work with management and the Board. Except as described in Item 6 and this Item 4, the Reporting Persons do not currently have any plans or proposals that relate to or would result in any of the actions specified in clause (a) through (j) of this paragraph.

The Reporting Persons reserve the right, based on all relevant factors and subject to applicable law or other restrictions, at any time and from time to time, to acquire additional securities of the Issuer, dispose of some or all of the shares of Common Stock or such other securities, in each case in open market or private transactions, block sales or otherwise, and review or reconsider their position, change their purpose, take other actions (including actions that could involve one or more of the types of transactions or have one or more of the results described in clauses (a) through (j) of the foregoing paragraph of this Item 4) or formulate and implement plans or proposals with respect to any of the foregoing.

(a) & (b) As of the date hereof, the Reporting Persons beneficially own, in the aggregate, 2,000,000 shares of Common Stock, which represents approximately 8.6% of the Common Stock issued and outstanding.
