This Amendment No. 1 to Schedule 13D (this “Amendment No. 1”) is being filed with respect to the Class A Common Stock, $0.001 par value (the “A-Common”), of Shake Shack, Inc., a Delaware corporation (the “Issuer”), to amend the Schedule 13D filed on February 17, 2015 (as amended by this Amendment No. 1, the “Schedule 13D”).  Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to them in the Schedule 13D filed on February 17, 2015.

ITEM 4.PURPOSE OF TRANSACTION

Item 4 of the Schedule 13D is amended to reflect the following:

The SEG Direct Holders participated in a registered secondary offering of A-Common shares of the Issuer, which closed on August 18, 2015 (the “Secondary Public Offering”).  In connection with the Secondary Public Offering, SEG and SEG II exchanged LLC Interests for A-Common shares on a one for one basis and sold such A-Common shares in the offering.  Simultaneously with the exchange, an equivalent number of B-Common shares held by SEG and SEG II were cancelled without consideration pursuant to the Amended and Restated Certificate of Incorporation of the Issuer.  In addition, SEG Offshore sold A-Common shares held by it in the Secondary Public Offering.

Each of Mr. Guillemin and the SEG Funds have agreed, pursuant to a lock-up agreement (the “Secondary Lock-Up Agreement”) with the underwriters for the Secondary Public Offering, that for 90 days following the date of the final prospectus with respect to the Secondary Public Offering, he or it will not, subject to limited exceptions and subject to extension in specified circumstances, offer, pledge, announce the intention to sell, sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, or take or propose to take actions to transfer to another, all or a portion of the economic consequences of ownership of, any shares of A-Common, B-Common, or any securities convertible into or exercisable or exchangeable for shares of the Issuer’s common stock.

Except as disclosed in this Schedule 13D, none of the members of the SEG Group, including none of the Reporting Persons, has any current plans or proposals which relate to or would result in any of the events described in clauses (a) through (j) of the instructions to Item 4 of Schedule 13D.  The Reporting Persons, however, will take such actions with respect to the Reporting Persons’ investments in the Issuer as they deem appropriate in light of existing circumstances from time to time and reserve the right to acquire or dispose of securities of the Issuer, to enter into hedging relationships with respect to such securities, or to formulate other purposes, plans, or proposals in the future depending on market conditions and/or other factors.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

Items 5(a) and 5(b) of the Schedule 13D are amended to reflect the following:

As of the date of this statement, (i) SEG is the record owner of 338,127 shares of B-Common and LLC Interests, (i) SEG II is the record owner of 1,267,658 shares of B-Common and LLC Interests, (iii) SEG Offshore is the record owner of  2,164,949 shares of A-Common, and (iv) Mr. Guillemin is the record owner of the Guillemin Options.  Each member of the SEG Group beneficially owns the number of shares of  A-Common, on an as-converted basis, as set forth below.  The percentage of A-Common beneficially owned by each such member of the SEG Group is based on 36,250,000 shares of A-Common outstanding, on an as-converted basis, as of August 5, 2015.

ReportingPersons	Number of Shares With Sole Voting and Dispositive Power	Number* of Shares With Shared Votingand Dispositive Power	AggregateNumber* ofSharesBeneficially Owned	Percentageof ClassBeneficially Owned

Other directors and officers of SEG Offshore	0	2,548,516	2,548,516	6.0%

*All share numbers presented in this table assume full conversion of B-Common and LLC Interests to A-Common.

Due to their relationships with the SEG Direct Holders, each of Select Equity, SEG Holdings, SEG II Holdings, Select Equity GP and Mr. Loening may be deemed to have shared voting and investment power with respect to the Equity Interests beneficially owned by the SEG Direct Holders. As such, Select Equity, SEG Holdings, SEG II Holdings, Select Equity GP and Mr. Loening may be deemed to have shared beneficial ownership over such Equity Interests.  SEG and SEG Holdings disclaim beneficial ownership of the Equity Interests held directly by SEG II and SEG Offshore;  SEG II and SEG II Holdings disclaim beneficial ownership of the Equity Interests held directly by SEG and SEG Offshore; and SEG Offshore disclaims beneficial ownership of the Equity Interests held directly by SEG and SEG II.

Page 11 of 14

Additionally, by virtue of the various agreements and arrangements among the SEG Funds described in this Schedule 13D and the other members of the Voting Group (the other members of the Voting Group, the “Non-SEG Members”), the Non-SEG Members may be deemed to be members of a “group” with the Reporting Persons.  None of the Non-SEG Members are Reporting Persons on this Schedule 13D, and any obligations any of them may have under Section 13(d) of the Act would have to be satisfied on one or more separate filings.  To the extent that any Non-SEG Member beneficially owns Equity Interests, the Reporting Persons may be deemed to beneficially own any such Equity Interests, but expressly disclaim, to the extent permitted by applicable law, beneficial ownership thereof.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER

Item 6 of the Schedule 13D is amended to reflect the following:

In connection with the Secondary Public Offering, Mr. Guillemin and the SEG Funds  have entered into the Secondary Lock-Up Agreement, as described in Item 4.
