NATURE OF OPERATIONS

Shake Shack Inc. was formed on September 23, 2014 as a Delaware corporation for the purpose of facilitating an initial public offering and other related transactions in order to carry on the business of SSE Holdings, LLC and its subsidiaries. Unless the context otherwise requires, references to "we," "us," "our," "Shake Shack" and the "Company" refer to Shake Shack Inc. and its subsidiaries, including SSE Holdings, LLC, which we refer to as "SSE Holdings."

We operate and license Shake Shack restaurants ("Shacks"), which serve hamburgers, hot dogs, chicken, crinkle cut fries, shakes, frozen custard, beer, wine and more. As of December 28, 2016, there were 114 Shacks in operation, system-wide, of which 64 were domestic company-operated Shacks, seven were domestic licensed Shacks and 43 were international licensed Shacks.

Initial Public Offering

On February 4, 2015, we completed an initial public offering ("IPO") of 5,750,000 shares of our Class A common stock at a public offering price of $21.00 per share, which includes 750,000 shares issued pursuant to the underwriters' over-allotment option. We received $112,298 in proceeds, net of underwriting discounts and commissions, which we used to purchase newly-issued membership interests from SSE Holdings at a price per interest equal to the initial public offering price of our Class A common stock.

Organizational Transactions

In connection with the IPO, we completed the following transactions (the "Organizational Transactions"):

▪

We amended and restated the limited liability company agreement of SSE Holdings (as amended, the "SSE Holdings LLC Agreement") to, among other things, (i) provide for a new single class of common membership interests in SSE Holdings ("LLC Interests"), (ii) exchange all of the membership interests of the then-existing holders of SSE Holdings for LLC Interests and (iii) appoint Shake Shack Inc. as the sole managing member of SSE Holdings. See Note 11.

▪

We amended and restated our certificate of incorporation to, among other things, (i) provide for Class B common stock with voting rights but no economic interests (where "economic interests" means the right to receive any distributions or dividends, whether cash or stock, in connection with common stock) and (ii) issue shares of Class B common stock to the then-existing holders of SSE Holdings on a one-to-one basis with the number of LLC Interests they own. See Note 11.

▪

We acquired, by merger, two entities that were owned by former indirect members of SSE Holdings, for which we issued 5,968,841 shares of Class A common stock as merger consideration (the "Mergers"). The only assets held by the two merged entities prior to the merger were 5,968,841 LLC Interests and a corresponding number of shares of Class B common stock. Upon consummation of the Mergers, we canceled the 5,968,841 shares of Class B common stock and recognized the 5,968,841 of LLC Interests at carrying value, as the Mergers are considered to be transactions between entities under common control.

Following the completion of the Organizational Transactions, we owned 33.3% of SSE Holdings. The non-controlling interest holders subsequent to the Merger owned the remaining 66.7% of SSE Holdings. As a result of the Organizational Transactions, we became the sole managing member of SSE Holdings and, although we had a minority economic interest in SSE Holdings, we had the sole voting power in, and control the management of, SSE Holdings. Accordingly, we consolidated the financial results of SSE Holdings and reported a non-controlling interest in our consolidated financial statements.

As the Organizational Transactions are considered transactions between entities under common control, the financial statements for periods prior to the IPO and Organizational Transactions have been adjusted to combine the previously separate entities for presentation purposes.

Secondary Offering

In August 2015, we completed a secondary offering of 4,000,000 shares of our Class A common stock at a price of $60.00 per share. All of the shares sold in the offering were offered by certain non-controlling interest holders. We did not receive any proceeds from the sale of shares of Class A common stock offered by the aforementioned non-controlling interest holders. The shares sold in the offering consisted of (i) 844,727 existing shares of Class A common stock held and (ii) 3,155,273 newly-issued shares of Class A common stock issued in connection with the redemption of 3,155,273 LLC Interests by the non-controlling interest holders that participated in the offering. Simultaneously, and in connection with the redemption, 3,155,273 shares of Class B common stock were surrendered by non-controlling interest holders and canceled. Additionally, in connection with the redemption, we received 3,155,273 LLC Interests, increasing our total ownership interest in SSE Holdings.

USC Merger

Pursuant to a Stockholders Agreement, dated as of February 4, 2015, as amended, by and among Daniel H. Meyer and his affiliates (the "Meyer Group") and other parties thereto, the Meyer Group has the right to cause all of the stock of Union Square Cafe Corp. ("USC") and Gramercy Tavern Corp. ("GT") to be converted into and exchanged for shares of our Class A common stock pursuant to a tax-free reorganization (each, a "Reorganization"). In December 2015, the Meyer Group exercised their right with respect to USC. The Reorganization was structured as a two-step merger, whereby (i) a newly-formed wholly-owned subsidiary of the Company merged with and into USC, then (ii) USC merged with and into the Company (the foregoing transactions are collectively referred to as the "USC Merger"). Prior to the USC Merger, USC owned 1,727,804 LLC Interests and an equivalent number of shares of our Class B common stock. In the USC Merger, (i) 1,727,804 shares of Class A common stock were issued to the stockholders of USC, with each stockholder receiving newly-issued shares of Class A common stock in an amount equivalent to the number of shares of USC held by such stockholders; (ii) 1,727,804 shares of Class B common stock held by USC were cancelled; and (iii) 1,727,804 LLC Interests held by USC were transferred to us.

As of December 28, 2016, we owned 69.1% of SSE Holdings and the non-controlling interest holders own the remaining 30.9% of SSE Holdings.
