The principal executive offices of each of the Reporting Persons are located at 130 King Street West, Suite 300, P.O. Box 399, Toronto, Ontario M5X 1E1.

The Partnership is the indirect holding company of BKH. Each of the Reporting Persons is an indirect holding company for The TDL Group Corp. (“Tim Hortons”) and its consolidated subsidiaries, Burger King Worldwide, Inc. (“Burger King”) and its consolidated subsidiaries (including BKC and its parent), and Popeyes Louisiana Kitchen, Inc.

As the sole general partner of Partnership, RBI may also be deemed to indirectly beneficially own the shares of Carrols Common Stock beneficially owned by Partnership.

Item 3 of the Schedule 13D is hereby amended and supplemented by the following information:

On April 30, 2019, the Issuer consummated the transactions contemplated by the Agreement and Plan of Merger dated as of February 19, 2019 (the “Cambridge Merger Agreement”) by and among the Issuer, OldCRG, GRC MergerSub Inc. (“Carrols MergerSub”), GRC MergerSub LLC (“Carrols CFP MergerSub”) and Cambridge Franchise Partners, LLC (“CFP”), Cambridge Franchise Holdings, LLC, a wholly owned subsidiary of CFP (“Cambridge Holdings”), and New CFH, LLC (“New CFH”) which consisted of (i) the merger and of Carrols MergerSub and OldCRG with OldCRG as the surviving entity which resulted in OldCRG becoming a wholly-owned subsidiary of the Issuer, (the “Holding Company Reorganization”) and (ii) the merger of Carrols CFP MergerSub and New CFH with New CFH as the surviving entity pursuant to which the Issuer purchased the business of the subsidiaries of Cambridge Holdings, which includes 165 Burger King® restaurants, 55 Popeyes® restaurants, six convenience stores and certain real property in consideration of shares of 7,364,413 shares of Carrols Common Stock and 10,000 shares of Series C Convertible Preferred Stock, par value $0.01 per share, of NewCRG (the “NewCRG Series C Preferred Stock”). The NewCRG Series C Preferred Stock is subject to certain restrictions on conversion (the “Cambridge Conversion Limitation”). However, pursuant to the Cambridge Merger Agreement, the Issuer agreed to propose at the next annual meeting of the Issuer’s stockholders and any subsequent meeting of the Issuer’s stockholders, if necessary, a proposal to remove the Cambridge Conversion Limitation.

Pursuant to the Holding Company Reorganization, each share of Carrols Common Stock issued and outstanding immediately prior to the Holding Company Reorganization was automatically converted into an equivalent corresponding share of Carrols Common Stock, having the same designations, rights, powers and preferences and the qualifications, limitations and restrictions as the corresponding share of Carrols Common Stock being converted. Each share of OldCRG Series B Convertible Preferred Stock, par value $0.01 per share (the “OldCRG Series B Convertible Preferred Stock”), issued and outstanding immediately prior to the Holding Company Reorganization (and held by the Investors was automatically converted into an equivalent corresponding share of NewCRG Series B Convertible Preferred Stock, par value $0.01 per share (the “NewCRG Series B Preferred Stock”), having the same designations, rights, powers and preferences and the qualifications, limitations and restrictions as the corresponding share of OldCRG Series B Convertible Preferred Stock being converted. Accordingly, upon consummation of the Holding Company Reorganization, the Investors became stockholders of the Issuer. Following the consummation of the Holding Company Reorganization, shares of Carrols Common Stock will continue to trade on the NASDAQ Global Market symbol “TAST”.

On April 30, 2019, two subsidiaries of the Reporting Persons (Burger King Corporation (“BKC”) and Blue Holdco 1, LLC) (collectively the “Investors”), Cambridge Holdings and the Issuer entered into a Voting Agreement (the “Cambridge Voting Agreement”), pursuant to which (i) the Investors will agree to vote their respective shares of NewCRG Series B Convertible Preferred Stock that they hold in favor of a proposal at any annual or special meeting of the Issuer’s stockholders, or execute written consents in lieu of any annual or special meeting, to remove the Cambridge Conversion Limitation and against any action, proposal, transaction or agreement that would reasonably be expected to impede, interfere with, delay, disadvantage or adversely effect the removal of the Cambridge Conversion Limitation and (ii) Cambridge Holdings will agree to vote its shares of Carrols Common Stock that it holds in favor of a proposal at any annual or special meeting of the Issuer’s stockholders, or execute written consents in lieu of any annual or special meeting, to amend the Certificate of Designations of the NewCRG Series B Preferred Stock (the “Series B Certificate of Designations”) changing the definition of (A) the Director Step-Down Date (as defined in the Series B Certificate of Designations) to occur upon the first date on which the number of shares of Carrols Common Stock into which the outstanding shares of NewCRG Series B Preferred Stock held by the Investors are then convertible constitute less than 11.5% of the total number of outstanding shares of Carrols Common Stock and (B) Director Cessation Date (as defined in the NewCRG Series B Certificate of Designations) as the first date on which the number of shares of Carrols Common Stock into which the outstanding shares of NewCRG Series B Preferred Stock held by the Investors are then convertible constitute less than 7.5% of the total number of outstanding shares of Carrols Common Stock (collectively the “Director Step Down Definitions”). The Voting Agreements will terminate upon the date on which the removal of the Cambridge Conversion Limitation and the Director Step Down Definitions are approved by the Issuer’s stockholders.

On April 30, 2019, the Investors, OldCRG, Carrols Corporation and the Issuer entered into the Consent Agreement (the “Consent Agreement”) which provides, among other things, that the Issuer (i) include in the Issuer’s proxy statement for the next annual meeting of stockholders, a proposal soliciting the Issuer’s stockholders’ affirmative vote at such annual meeting of stockholders for approval of a modification of the following definitions

included in the Series B Certificate of Designations: (a) “Director Step-Down Date” to be modified by replacing the percentage set forth therein (14.5%) with 11.5% and (b) “Director Cessation Date” to be modified by replacing the percentage set forth therein (10%) with 7.5% to reflect the increase in the number of directors of the Issuer (the “Stockholder Approval”) and (ii) use its commercially reasonable efforts to solicit its stockholders’ approval of such proposal and to cause the board of directors of the Issuer to recommend to the stockholders that they vote in favor of such proposal, unless the board of directors of the Issuer determines, after consultation with outside legal counsel, that making such recommendation would reasonably be expected to cause the board of directors to be in breach of its fiduciary duties under applicable law. If the Stockholder Approval is not obtained at an annual meeting of stockholders of the Issuer, then the Issuer will use its commercially reasonable efforts (including continuing to recommend the Stockholder Approval to the stockholders) to obtain the Stockholder Approval at each of the following meetings of the stockholders of the Issuer until such Stockholder Approval is obtained. The Issuer entered into the forgoing obligations in consideration for the consent of the Investors under the Series B Certificate of Designations for certain matters related to the mergers and the Holding Company Reorganization.

The foregoing summaries of the Cambridge Voting Agreement and the Consent Agreement are not intended to be complete and are qualified by reference to the copy of such documents included as an exhibit to this Schedule 13D and incorporated herein by reference.

The disclosures in Item 3 above are hereby incorporated by reference into this Item 4.

Item 4 of the Schedule 13D is hereby amended and supplemented by the following information:

(d) Pursuant to the Series B Certificate of Designations, the Investors have the right to elect two members of the Issuer’s Board of Directors (the “Board”) as Class B Directors (as defined in the Series B Certificate of Designations) until the date on which the number of shares of Carrols Common Stock into which the outstanding shares of NewCRG Series B Preferred Stock held by the Investors are then convertible constitutes less than 14.5% of the total number of outstanding shares of Carrols Common Stock (the “Director Step-Down Date”). From the Director Step-Down Date to the date on which the number of shares of Carrols Common Stock into which the outstanding shares of NewCRG Series B Preferred Stock held by the Investors are then convertible constitute less than 10% of the total number of outstanding shares of Carrols Common Stock, the Investors will have the right to elect one member to the Board as a Class B Director. The Class B Directors are a separate class of directors on the Board from the Class I, Class II and Class III directors of the Board. José E. Cil and Matthew Dunnigan, executive officers of the Reporting Persons, are the two directors designated by the Investors to serve as the Class B Directors of the Issuer.

At the Issuer’s next annual meeting annual meeting of the Issuer’s stockholders and any subsequent meeting of the Issuer’s stockholders, if necessary, the Issuer will include a proposal to amend the Series B Certificate of Designations to amend the Director Step Down Definitions, as described above.

The foregoing summary of the Series B Certificate of Designations is not intended to be complete and is qualified by reference to the copy of such document included as an exhibit to this Schedule 13D and incorporated herein by reference.

Such shares of Carrols Common Stock represent 17.5% of the outstanding Carrols Common Stock as of the date of this Amendment. As the sole general partner of Partnership, RBI may be deemed to indirectly beneficially own the shares of Carrols Common Stock directly beneficially owned by Partnership’s indirect wholly-owned subsidiaries.

As a result of the Cambridge Voting Agreement, the Reporting Persons and Cambridge Holdings have formed a “group” for purposes of Section 13(d)(3) of the Exchange Act, and Rule 13d-5(b)(1) thereunder. The group formed thereby beneficially owns an aggregate of 16,778,993 shares of Carrols Common Stock, or 31.2% of the outstanding shares of Carrols Common Stock. Based solely on information provided by Cambridge Holdings, Cambridge Holdings beneficially owns 7,364,413 shares of Carrols Common Stock, or 16.6% of the outstanding shares of Carrols Common Stock. Each of the Reporting Persons expressly disclaims beneficial ownership over any shares of Carrols Common Stock that they may be deemed to beneficially own solely by reason of the Cambridge Voting Agreement.
